Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a sludge lift pump connection device that is easy to maintain. Background Technology

[0002] As we all know, in industrial and agricultural production processes, such as at the bottom of fishponds and lakes, a large amount of sludge is generated and accumulates. If this sludge undergoes processing, filtration, and solidification, it can be transformed from waste into valuable resources. The reprocessed and solidified sludge can not only be used for planting grass and flowers, but also for constructing roadbeds and slopes.

[0003] Sludge lift pumps are needed to lift sludge from the bottom of sewage tanks and other tanks. Sludge lift pumps are mostly used in underground water tanks or sealed equipment. During maintenance, the water in the container must be emptied before entering for maintenance, which poses the risk of suffocation in the confined space and the problem of difficulty in emptying the container. Utility Model Content

[0004] The purpose of this invention is to provide a sludge lift pump connection device that is easy to maintain, thereby solving the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a sludge lift pump connection device that is easy to maintain. It includes a sludge tank and two sludge lift pumps installed inside the sludge tank. The two sludge lift pumps are connected to each other by a connecting assembly. The sludge lift pumps are connected to the inner wall of the sludge tank by a first sliding assembly. One inlet end of the sludge lift pump is connected to a flexible hose via a flange, and one outlet end of the sludge lift pump is connected to a sewage discharge steel pipe via a flange. The sewage discharge steel pipe is Z-shaped, and the pipe body is connected to the inner wall of the sludge tank via a second sliding assembly. The other end of the sewage discharge steel pipe protrudes out of the sludge tank and is connected to a horizontal pipe via a flange.

[0007] Furthermore, the connecting assembly includes a connecting plate, the two ends of which are respectively connected to the two sludge lifting pumps.

[0008] Furthermore, the connecting plate is provided with several mud-draining holes.

[0009] Furthermore, the first sliding assembly includes a first slide rail installed on the inner wall of the sludge tank, and a first slider is connected to one end of the two sludge lifting pumps near the inner wall of the sludge tank via a linkage rod. The first slider is slidably connected to the first slide rail.

[0010] Furthermore, the top of the sludge tank is hinged with a cover plate, and the cover plate has a through hole for the sewage discharge steel pipe to pass through.

[0011] Furthermore, a handle is installed on the cover plate.

[0012] Furthermore, the second sliding assembly includes a second slide rail installed on the inner wall of the sludge tank and two upper and lower second sliders installed on the sewage discharge steel pipe, with the second sliders slidably connected to the second slide rail.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This invention uses two sets of sliding components to restrict the position of the sludge lifting pump and the sewage discharge steel pipe, which makes it easy to lift the sludge lifting pump and the sewage discharge steel pipe directly from the sludge tank and take them to an open space for maintenance during maintenance. This eliminates the need to drain the liquid from the sludge tank and avoids safety risks during maintenance. Attached Figure Description

[0020] like Figure 1-3 As shown, a sludge lift pump connection device that is easy to maintain includes a sludge tank 1 and two sludge lift pumps 2 disposed inside the sludge tank 1. The two sludge lift pumps 2 are connected to each other by a connecting assembly. The connecting assembly includes a connecting plate 6, with both ends of the connecting plate 6 connected to the two sludge lift pumps 2 respectively. The connecting plate 6 has a plurality of sludge dropping holes 7, which facilitates the sludge to fall from the sludge dropping holes 7 when the sludge lift pump 2 is lifted, thereby reducing the lifting resistance.

[0021] The sludge lift pump 2 and the inner wall of the sludge tank 1 are connected by a first sliding assembly. The first sliding assembly includes a first slide rail 8 installed on the inner wall of the sludge tank 1. A first slider 10 is connected to one end of each sludge lift pump 2 near the inner wall of the sludge tank 1 via a linkage rod 9. The first slider 10 is slidably connected to the first slide rail 8. The first sliding assembly limits the position of the sludge lift pump 2, ensuring accurate positioning when it is placed in the sludge tank 1 and preventing the wastewater in the sludge tank 1 from shifting the position of the sludge lift pump 2.

[0022] The inlet end of the sludge lifting pump 2 is connected to a flexible hose 3 via a flange, and the outlet end of the sludge lifting pump 2 is connected to a sewage discharge steel pipe 4 via a flange. The sewage discharge steel pipe 4 is Z-shaped, and its body is connected to the inner wall of the sludge tank 1 via a second sliding assembly. The second sliding assembly includes a second slide rail 14 installed on the inner wall of the sludge tank 1 and two upper and lower second sliders 15 installed on the sewage discharge steel pipe 4. The second sliders 15 are slidably connected to the second slide rail 14. The position of the sewage discharge steel pipe 4 is defined by the second sliding assembly.

[0023] The top of the sludge tank 1 is hinged with a cover plate 11. The cover plate 11 has a through hole 12 for the sewage discharge steel pipe 4 to pass through. The other end of the sewage discharge steel pipe 4 protrudes from the through hole 12 into the sludge tank 1 and is connected to a horizontal pipe 5 through a flange. A handle 13 is installed on the cover plate 11.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
