Description

Technical Field

[0001] This utility model is used in sedimentation tanks of waterworks, specifically a sludge suction device for sedimentation tanks. Background Technology

[0002] The existing large-scale sludge suction devices (i.e., sludge suction trolleys) in the sedimentation tanks of existing water treatment plants cannot reach corners, resulting in dead zones where sludge accumulates severely. This accumulation of sludge in these corners can lead to changes in the water quality of the sedimentation tank. The main reason is that the angle and depth of the sludge suction hopper at the bottom of the existing sludge suction machine are fixed, and the suction path is also fixed during operation, thus making it impossible to treat the sludge in the corners. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a sludge suction device for sedimentation tanks, which can move horizontally and rotate to wash out sludge from dead corners.

[0004] (II) Technical Solution A sludge suction device for a sedimentation tank includes a sludge suction trolley device, and further includes a sludge suction trolley, a guardrail track, and a sludge discharge branch pipe. The guardrail track is provided along one side of the dead corner of the sludge suction trolley device. The sludge suction trolley slides and moves along the guardrail track. The bottom of the sludge suction trolley is provided with a downward-extending sludge suction pipe. The sludge suction trolley is connected to the sludge discharge branch pipe through a detachable sludge suction hose. The sludge discharge branch pipe is further connected to the sludge suction trolley device.

[0005] Preferably, the suction truck includes a sliding bracket and a universal quick-connect coupling mounted thereon.

[0006] Preferably, the sliding bracket is slidably connected to the guardrail track by two pairs of symmetrically arranged pulleys.

[0007] Preferably, the upper part of the universal quick connector is connected to the detachable suction hose via a pagoda connector, and the lower part is detachably connected to the suction pipe via a flange.

[0008] Preferably, the universal quick connector is rotatably connected to the sliding bracket via a bearing.

[0009] Preferably, the suction pipe is provided with a suction hopper at the bottom.

[0010] Preferably, the mud discharge branch pipe is provided with several valve quick-connect interfaces for connecting detachable mud suction hoses.

[0011] Preferably, the valve quick-connect interface has four pre-installed and evenly distributed ports.

[0012] Preferably, the sludge suction truck, guardrail track, and sludge discharge branch pipe are all made of stainless steel.

[0013] Preferably, the detachable suction hose is a PVC pipe.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a new type of sludge suction device for sedimentation tanks. This product sucks up sludge from corners through the flared mouth at the bottom. At the same time, its interface can rotate 360 ​​degrees. The original interface is fixed, so this product adopts a quick-release structure in many places. The depth is adjustable and it is flexible to use. This product can be used to clean up sludge without dead corners in any corner that the existing sludge suction machine cannot reach. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings, wherein the same parts are represented by the same reference numerals. It should be noted that the terms “front”, “rear”, “left”, “right”, “upper” and “lower”, “bottom” and “top” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific part, respectively.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Design concept: By combining the already installed sludge suction machine (sludge suction trolley device) and utilizing the existing sludge suction negative pressure device, a mobile sludge suction device can be added to achieve 360° rotation sludge suction, thus eliminating the problem of sludge suction in dead corners.

[0020] Example: like Figures 1-5 As shown, the present invention provides a sludge suction device for sedimentation tanks, including a sludge suction trolley device 1, and further including a sludge suction trolley 2, a guardrail track 3, and a sludge discharge branch pipe 4. The guardrail track 3 is provided along one of the dead corners of the sludge suction trolley device 1, and the sludge suction trolley 2 slides and moves along the guardrail track 3. The bottom of the sludge suction trolley 2 is provided with a downward-extending sludge suction pipe 5, and the bottom of the sludge suction pipe 5 is provided with a sludge suction hopper 7. The sludge suction trolley 2 is connected to the sludge discharge branch pipe 4 through a detachable sludge suction hose 6, which is a PVC pipe. The sludge discharge branch pipe 4 is further connected to the sludge suction trolley device 1.

[0021] The sludge suction cart 2 of this product includes a sliding bracket 21 and a universal quick connector 22 mounted on it. The sliding bracket 21 is slidably connected to the guardrail track 3 by two pairs of symmetrically arranged pulleys 23. The upper part of the universal quick connector 22 is connected to the detachable sludge suction hose 6 through the pagoda connector 24, and the lower part is detachably connected to the sludge suction pipe 5 through the flange 25. The depth can be adjusted by replacing the sludge suction pipe 5 with different lengths. In addition, the universal quick connector 22 is rotatably connected to the sliding bracket 21 through the bearing 26, which can realize 360° rotation sludge suction without leaving any dead angles.

[0022] The mud discharge branch pipe 4 of this product is equipped with several valve quick-connect interfaces 8 for connecting to the detachable mud suction hose 6. More specifically, four valve quick-connect interfaces 8 are reserved and evenly distributed, and their docking positions can be adjusted according to the moving position of the mud suction truck 2.
