6 Function

6.1 General Function Description

The Bucket Rake Bar Screen comprises a basic frame, the Bucket Rake with wiper, the lateral guide for the Bucket Rake carriage, the rake grid, the rope drum and the required drives. In the further processing course of the raked goods, a container, conveyor or press may be located. The gross rake mechanically cleans liquids, mainly community and industrial sewage. The liquid flows through a channel into which the lateral guides for the Bucket Rake carriage are installed. Lifting and lowering the Bucket Rake takes place via rope drum with round strand ropes. The rake grid keeps back organic and inorganic coarse material. The retained coarse material covers the rake grid, reducing the free grid area. The throughput amount drops or the water level difference (calculated from water level height before and after the rake grid) increases. If a speci-fied threshold value is exceeded, the Bucket Rake is moved down by the rope drum drive. The Bucket Rake enters the open channel’s sewage until the lower end point is reached. The Bucket Rake is closed and then moved up with the collected coarse material. Before the up-per end point is reached, the Bucket Rake hits the wiper, which wipes the raked goods from the Bucket Rake by even lifting. The raked goods slide down an ejection chute and into a container. The gross rake is automatically started and stopped via control depending on water level difference (or after a set interval).

6.2 Electrical Control (for a suggestion, also see Chap. 7)

6.2.1 Regular Operation Use the selection switch Hand - 0 - Auto at the local control panel to pre-select the operating mode: In switch position “Auto”, the permissible movement directions are released and the gross rake automatically performs the cleaning programme. In switch position “Hand”, only the permitted motion directions are released. In switch position “0”, the plant is stopped. The following motion directions are possible: Open Bucket Rake , limited by limit switch or time. The limit switch is at the hydraulic linear drive. Time is implemented by a time component. Close Bucket Rake , limited by limit switch. The limit switch is at the hydraulic linear drive. Bucket Rake carriage down, limited by a rotary encoder. The rotary encoder is located at the rope drum.

32


Bucket Rake carriage up, limited by a rotary encoder. The rotary encoder is located at the rope drum. Locking areas: To ensure that the gross rake does not cause any damage to the ejection chute or the rake grid, two locked areas were integrated in the control. Locked area 1: The first locked area is between the Bucket Rake carriage end position “top” and approx. 0.5m below the ejection chute. The Bucket Rake carriage can move down only at “maximum” partially opened Bucket Rake in this locked area 1, so that the Bucket Rake teeth do not get caught at the ejection chute. Since the position “Bucket Rake maximum partial opening” has no limit switch, this position is im-plemented with a timer unit. This means that this locked area 1 will only permit opening of the Bucket Rake to the “maximum” partial opening. Opening of the Bucket Rake in partial steps is possible. When the Bucket Rake Bar Screen is in the “maximum” partially opened condition, the Bucket Rake is closed a little in this position and repeated opening of the Bucket Rake is only possible after the Bucket Rake has closed com-pletely and the limit switch “Bucket Rake closed” has been operated. Locked area 2: The second locked area is directly adjacent to the first and located below the one described above. This locked area 2 goes down to the “Bucket Rake carriage end position”. To move the Bucket Rake carriage all the way down in this locked area 2, the Bucket Rake must be opened completely. This means that the limit switch “Bucket Rake open” must be operated. Opening and closing the Bucket Rake is possible only with the Bucket Rake carriage stationary in this area. This is also possible in partial steps. Automatic process of a cleaning cycle: The gross rake is in the initial position. The Bucket Rake carriage is on top and the Bucket Rake is “maximum” partially opened. The starting command by the level measurement (water level difference measurement) or working time/break control starts downwards movement of the Bucket Rake carriage and full opening of the Bucket Rake . The carriage moves to the lower end position with the Bucket Rake open. When the end position is reached, the rope drum drive stops. The hydraulic linear drive closes the Bucket Rake , so that the raked goods in front of the rake grid can be taken up. When the Bucket Rake is closed, the rope drum drive changes its rotating direction and moves up with the full Bucket Rake . In a specified dripping position (above the rake grid), the Bucket Rake carriage stops for 15 sec-onds. After this item, the Bucket Rake carriage continues to move up. Before the upper end point is reached, the Bucket Rake moves past the ejection chute and then hits the wiper. While the Bucket Rake continually moves on to the upper end point, the wiper wipes the raked goods from the Bucket Rake . The raked goods fall into the ejection chute and slide down into a container, press or conveyor.

33


When the Bucket Rake has reached the upper end point, the rope drum drive is switched off. After a waiting time of 2 seconds, the Bucket Rake is moved to the position “maximum” partially opened. The cleaning cycle is completed and the gross rake is in its starting position. The cleaning cycle is repeated until the water level difference undercuts the switch-off value. When the water level difference exceeds the switch-on value again, another cleaning cycle starts and the above function process is repeated. Starting a cleaning cycle: When the gross rake is in the starting position (Bucket Rake carriage on top and Bucket Rake “maximum” partially opened) and the hand switch is put from zero to automatic operation, a clean-ing cycle is always started, independent of level difference or working time.

6.2.2 Irregular Operation If the level measurement fails, the rake is operated by work/break time control. If the following ma-chines are subject to interference or operating mode -0- (off) is selected, the rake is switched off to prevent damage and overfilling. When operating the emergency stop button, the machines associated with the emergency circuit are switched off. Repeated start-up of the machines takes place after confirmation.

6.2.3 Loose Rope Monitoring The rake is equipped with a loose rope monitoring unit for the Bucket Rake carriage. When the loose rope monitoring unit of the Bucket Rake carriage triggers during downward mo-tion, the drive is stopped immediately and the following process is started:

• The rope drum drive changes its rotating direction and lifts the Bucket Rake carriage until the message loose rope monitoring Bucket Rake carriage is no longer pending.

• The drive stops again. • The drive changes direction again and moves the Bucket Rake carriage to

the lower end position to complete the clearing cycle • When the loose rope monitoring unit triggers again before the lower end position is

reached, the above process repeats. • If the loose rope monitoring unit triggers three times in sequence during a cleaning cycle,

the machine will switch to interference,

6.2.4 Manual Operation The Toggle Switch Used to Select the Operating Mode is set to “Hand” Push the pushbutton “Open Bucket Rake carriage”: When the Bucket Rake carriage is in locked area 1, the opening process of the Bucket Rake is permitted until the “maximum” partial opening is reached. When the Bucket Rake carriage is in locked area 2, the Bucket Rake can be opened all the way.

34


Pushing the pushbutton “Close Bucket Rake ”: This process can be performed without limitation in the locked areas 1 and 2. Pushing the pushbutton “Lower Bucket Rake carriage”: In locked area 1, this process can only be performed at “maximum” partial opening and is stopped at the end of locked area 1. In locked area 2, this process can only be performed at maximum opened Bucket Rake . When the Bucket Rake carriage reaches its lower end position, the downwards motion is stopped. Pushing the pushbutton “Lift Bucket Rake carriage”: In locked area 1, this process can only be performed with the Bucket Rake closed completely. In locked area 2, this process can be performed independently of Bucket Rake position.
