Description

Technical Field

[0001] The utility model belongs to the technical field of slag removal in biochemical ponds, and particularly relates to a device for automatically removing slag in a biochemical pond without underwater installation. Background Art

[0002] At present, the sewage treatment process in urban sewage treatment plants mainly includes primary treatment, secondary treatment and advanced treatment. Primary treatment is the physical treatment of sewage, mainly removing floating and suspended substances. The main treatment methods and equipment used are screen, grille, microfilter, etc. If the plant has a long operation time and the machines in primary treatment are aging and malfunctioning, the floating slag will flow to the secondary treatment or even the advanced treatment section along with the water flow. If not treated, the floating slag will cause blockage of aeration holes, lift pumps and even water distribution holes, and in severe cases, it will lead to on-site shutdown for maintenance. Considering the high depth of the biochemical pond in the secondary treatment and advanced treatment process sections, the large pool surface area and a large amount of activated sludge deposition, the risk of underwater operation is extremely high and the cost is extremely high. And shutting down for operation requires emptying hundreds of thousands of tons of sewage and sludge, resulting in large economic losses and complicated approval procedures. Therefore, there are few devices for removing floating slag in biochemical ponds.

[0003] In view of the above situation, there is an urgent need to propose an automatic slag removal device on the biochemical pond that does not require underwater installation. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a device for automatically removing slag in a biochemical pond without underwater installation, which is used to clean floating slag in the secondary treatment section, and effectively solves the problems of high safety risk of underwater operation, large economic loss of emptying the biochemical pond, difficult collection and removal of floating slag in the biochemical pond, and floating slag affecting the operation of equipment.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A device for automatically removing slag in a biochemical pond without underwater installation includes a slag removal frame. The slag removal frame includes an outer frame and an inner leakage frame, and the inner leakage frame is detachably connected to the outer frame; the outer frame is connected to a hoist by a towing rope.

[0007] Preferably, the inner leakage frame is connected to the outer frame by a buckle, and the inner leakage frame is arranged inside the outer frame.

[0008] Preferably, a handle is arranged at the edge of the inner leakage frame.

[0009] Preferably, a slag guiding pipe is arranged beside the slag removal frame.

[0010] Preferably, the slag guiding pipe is connected to the pool side guardrail by a flexible steel wire rope, and the pool side guardrail is arranged beside the biochemical pond.

[0011] Preferably, the hoist is installed on a rack, and the rack is installed beside the biochemical pond.

[0012] The utility model can achieve the following beneficial effects:

[0013] (1) The utility model utilizes the gravity movement of sewage in the biochemical pool through the slag guide pipe to finally collect the floating slag in the slag scoop frame for collection, which can effectively solve the problem that the biochemical pool is wide and deep, and the slag is difficult to collect, thereby improving the slag scooping efficiency. In addition, considering that the slag on the biochemical pool is in a block-like shape and due to the gravity of the water pipe itself, the slag guide pipe is composed of three PE pipes, which can effectively intercept the slag and realize the complete collection of the slag.

[0014] (2) In the utility model, the slag collecting frame is placed into the pool by a crane to collect the floating slag. The slag collecting frame is then lifted by a crane, and the sewage is automatically screened out. The floating slag is collected in the inner filter frame. The buckle is opened, the inner filter frame is taken out, and the floating slag is poured out to complete the collection and cleaning of the floating slag, thus avoiding the problem of the slag collecting device needing to be installed in the water. In addition, the slag collecting efficiency is high and the labor cost is low, which greatly reduces the safety risks and time and labor costs of manual slag collecting.
