Automatic cleaning equipment for sludge on surface of inclined tube of inclined tube sedimentation tank

Abstract

The utility model aims to solve the problem that a large amount of sludge is accumulated on the surface of an inclined tube of an inclined tube sedimentation tank, and provides automatic cleaning equipment for sludge on the surface of the inclined tube of the inclined tube sedimentation tank. A traditional manual high-pressure water gun cleaning method for emptying the sedimentation tank is changed, sludge in the middle layer of the sedimentation tank is accurately locked through the sludge cleaning head, and a large amount of sludge is directly sucked into the siphon to be discharged. The bristles at the bottom of the cleaning head can destroy the awning-shaped sludge structure on the surface of the inclined pipe and enable the sludge to be separated from the inclined pipe body, the free sludge enters the siphon pipe from the uniformly distributed suction inlets under the siphon effect, and finally the sludge is accurately swept in the middle layer of the sedimentation tank. The movable trolley drives the siphon and the sludge cleaning head to move slowly, so that timed automatic sludge cleaning is realized. Compared with a traditional method, the automatic cleaning equipment can reduce the labor intensity of workers, can also reduce waste of energy and water resources, and guarantees the implementation of the'energy-saving and consumption-reducing plan 'for enterprises.

Description

1. Technical Field

[0001] The utility model belongs to the technical field of tap water treatment and is mainly used for cleaning sludge in the inclined tube sedimentation tank of a water treatment plant. 2. Background Technology

[0002] A large amount of sludge often accumulates on the top of the inclined tube of the inclined tube sedimentation tank, causing a large amount of alum flowers to float up into the filter tank, causing the filter tank to be overloaded and affecting the water quality. The current common measure is to empty the sedimentation tank first and then manually clean it with a high-pressure water gun. Some water plants first empty the sedimentation tank and then use an automatic spray system to clean it. Regardless of the cleaning method, a large amount of sedimentation water will be discharged each time, and the workload is large and the power consumption is high, resulting in a significant increase in water treatment costs. III. Summary of the invention

[0003] The utility model provides an automatic cleaning device for sludge on the surface of an inclined tube of an inclined tube sedimentation tank, which mainly comprises a sludge cleaning head, a siphon and auxiliary facilities. Figure 2 As shown in the figure, it is composed of a tube body, an end cover, bristles, and a flexible joint. Side suction ports and front and rear suction ports are evenly distributed on both sides of the bristles and the end cover. By making a physical object, the sludge can be cleaned manually, and the sludge cleaning effect is very significant. The entire design system is as follows Figure 2 As shown in the figure, the sludge cleaning heads are installed on the siphon tube at a certain distance, and the siphon tube and the sludge cleaning heads are driven by the mobile trolley to move slowly in the horizontal and vertical directions of the siphon tube. The trolley is automatically controlled to start by the time relay and automatically stopped by the travel switch, which can ensure automatic operation and cleaning once a day. The system has a simple structure, strong versatility, easy disassembly, and is easy to operate in the early installation and debugging and later maintenance and repair. Compared with traditional methods, automatic cleaning equipment can not only reduce the production cost of enterprises. IV. Description of the drawings

[0008] Combination Figure 1 and Figure 2The specific implementation mode of the utility model is described in detail, the sludge cleaning head ( Figure 1 (As shown in the figure) bristles 6 are implanted at the bottom of the tube body 2, end covers 3 are fixed at both ends, and side suction ports 4 and front and rear suction ports 5 are evenly opened on the tube body 2 on both sides of the bristles 6 and the end covers 3, and a flexible joint 1 is left at the upper end, which not only enables the sludge cleaning head to be connected to the siphon 9 at different angles in the horizontal direction, but also facilitates later replacement. The sludge cleaning heads 12 are installed in parallel on the siphon 9 according to the required distance. The tube body 2 is cut according to the actual needs of the installation site, and the height of the sludge cleaning head 12 in the vertical direction is adjusted so that the bristles 6 of the sludge cleaning head 12 just touch the upper surface of the inclined tube 11 of the sedimentation tank. When the siphon 9 is filled with water, the start-stop valve 10 is opened at a fixed time, and the mobile car 8 immediately starts to move slowly with the siphon 9 and the sludge cleaning head 12. The brush 6 at the bottom of the cleaning head 12 begins to destroy the tent-like sludge structure on the surface of the inclined tube 11 to make the sludge separate from the inclined tube body. Under the action of siphon, the free sludge enters the siphon 9 from the evenly distributed front and rear suction ports 5 and the side suction ports 4. The drainage port of the siphon (9) is lower than the liquid level of the sedimentation tank during normal operation to form a negative pressure, and finally the sludge cleaning head 12 is used to accurately lock the sludge in the middle layer of the sedimentation tank, and a large amount of sludge is directly sucked into the siphon 9 for discharge, so as to achieve the effect of automatic cleaning of sludge at a fixed time. When the travel switch is touched at the end of a travel, the system will immediately close the start-stop valve 10, stop the movement of the mobile car 8, and wait for a cycle before the system starts to move in the opposite direction again, so that the sludge can be cleaned periodically. The sludge cleaning head 12 can also be directly connected to a hose to make a handheld sludge cleaning device to clean the sludge in the dead corner of the sedimentation tank.
