Description

Technical Field

[0001] The invention relates to the field of environmental protection equipment, in particular to the problem of clogging of suction pipes of sludge suction machines in large-scale sewage treatment plants and water plants. Background Art

[0002] At present, most of the sludge suction machines in sewage treatment plants and water plants are Figure 1 As shown in the figure, the suction pipe often gets clogged during operation, which reduces the suction effect and affects the water quality. Therefore, it is particularly important to clean the suction pipe after a certain period of use.

[0003] The existing cleaning methods are mostly divided into the following two types: 1. Use a bamboo pole to reach into the pipe and stir it manually to clean the pipe, which is not only time-consuming and laborious, but also has unsatisfactory cleaning effects. 2. Use pressurized water for backwashing, which is more troublesome and requires the sludge suction machine to be stopped first and the pressurized water source (such as fire water and pumps, etc.) to be connected; this cleaning method takes a long time to operate and will seriously affect the normal use of the equipment. Summary of the invention

[0004] In view of the above problems, the present invention proposes a sludge suction pipe cleaning tool which has a sophisticated structure, is easy to use, has good stability, good cleaning effect and high working efficiency. The tool can efficiently clean the suction pipe in the sludge suction machine without stopping the sludge suction machine, thereby avoiding various problems caused by suction pipe blockage.

[0011] S3, quick lifting: The operator holds the piston rod and quickly lifts the piston plate until the piston plate is pulled out of the mud suction pipe;

[0012] S4, judging whether the mud suction pipe is unobstructed, if yes, then the process ends, otherwise, the process returns to step S2.

[0013] It also includes a slow-insert and quick-lift assembly, which includes a base, a threaded rod, a threaded seat and a pair of drive assemblies. The cleaning tool has a piston rod and a piston plate. The outer wall of the piston rod is provided with an external thread to form a threaded rod.

[0014] The base is placed in the groove above the mud suction pipe, the threaded seat is slidably connected in the base, and a threaded hole matching the threaded rod is opened in the threaded seat;

[0031] The present invention Figure 1-11 As shown, the sludge suction machine includes a plurality of sludge suction pipes 2, a flow regulating valve 1 is provided at the top of the sludge suction pipe 2, and the sludge suction pipe cleaning tool includes a piston plate 4 and a piston rod 5, the piston plate 4 is in the shape of a disc adapted to the inner wall of the sludge suction pipe 2, and the piston plate 4 and the inner wall of the sludge suction pipe 2 are gap-matched, the piston rod 5 is arranged perpendicular to the piston plate 4, and one end of the piston rod 5 is fixedly connected to the center of the piston plate 4.

[0032] There are a plurality of piston rods 5 , the axes of which are distributed on the same straight line, and adjacent piston rods 5 are detachably connected via joints 6 .

[0033] The piston plate 4 is a 3mm thick steel plate, the piston rod 5 is a four-element flat water pipe, and the joint 6 is a four-element external joint. In this way, all components in this case are made of common materials on the market as raw materials, which has the advantages of low production cost and low use cost.

[0034] A method for cleaning a sludge suction pipe is performed by following the steps below:

[0035] S1. Arrange cleaning tools: Take a number of piston rods and complete the detachable connection between adjacent piston rods, wherein a piston plate is fixedly connected to one of the piston rods;

[0036] S2, slow insertion: the operator first opens the flow regulating valve 1, then holds the piston rod and slowly inserts the piston plate into the blocked mud suction pipe; at this time, due to the clearance between the piston plate and the mud suction pipe, that is, during the slow downward movement of the steel plate, there is a gap between the steel plate and the pipe wall, so the steel plate can slowly move downward without being blocked by air pressure or water pressure;

[0037] S3, quick lifting: the operator holds the piston rod and quickly lifts the piston plate until the piston plate is pulled out of the mud suction pipe; as the steel plate quickly moves upward, the gap between it and the mud suction pipe is not enough to allow air or water to quickly enter the bottom of the steel plate, so that the pressure difference between the inside and outside of the pipe increases suddenly, and finally, the blockage in the pipe can be squeezed out under the static pressure;

[0038] S4, judging whether the mud suction pipe is unobstructed, if yes, then end, otherwise return to step S2. In this way, the mud suction pipe in the mud suction machine can be efficiently cleaned without stopping the mud suction machine, thereby avoiding various problems caused by pipe blockage.

[0039] like Figure 4-11 As shown, the mud suction pipe cleaning tool also includes a slow insertion and quick lifting assembly, which includes a base 71, a threaded rod 72, a threaded seat 73 and a pair of driving assemblies. The cleaning tool has a piston rod and a piston plate. The outer wall of the piston rod is provided with an external thread to form the threaded rod 72.

[0040] The base 71 is placed in the groove above the mud suction pipe, the threaded seat 73 is slidably connected in the base 71, and a threaded hole adapted to the threaded rod 72 is opened in the threaded seat 73;

[0041] A pair of driving components are symmetrically arranged on both sides of the threaded seat 73. The driving components include a connecting rod 74, a sleeve 1 75, a sleeve 2 76 and a linear driving mechanism 77 (which can be a linear driver such as a pneumatic rod, a hydraulic rod, an electric push rod or a linear motor). The bottom end of the linear driving mechanism 77 is fixedly connected to the base 71, and its top end is hinged to the sleeve 1 75. The sleeve 2 76 is hinged to the middle of the base 71. One end of the connecting rod 74 is hinged to the side wall of the threaded seat 73, and the sleeve 1 75 and the sleeve 2 76 are passed through. In this way, the linear motion of the linear driving mechanism will drive the threaded seat to reciprocate up and down in the base under the transformation of the connecting rod.

[0042] When using, the operator can follow the steps below:

[0043] A1. Initialization: First, install the threaded rod into the threaded seat, and make the piston plate as close to the bottom of the threaded seat as possible; then start the linear drive mechanism to make the threaded seat move down to the lower limit position; due to the clearance between the piston plate and the mud suction pipe, the steel plate can move down slowly without being blocked by air pressure or water pressure;

[0044] A2, Slow insertion: The operator can use tools such as hand wheels and wrenches to rotate the threaded rod to drive the piston plate to gradually move downward;

[0045] A3. Quick lifting: The operator can start the linear drive mechanism, so that the sleeve drives the connecting rod to rotate quickly, thereby driving the threaded seat to rise quickly until the piston plate is pulled out of the mud suction pipe; as the piston plate quickly rises, the pressure difference between the inside and outside of the pipe suddenly increases, and finally, the blockage in the pipe can be squeezed out under the action of static pressure;

[0046] A4: Determine whether the mud suction pipe is unobstructed. If yes, the process ends; otherwise, the process returns to step A1.

[0047] The distance between the sleeve 2 76 and the linear drive mechanism 77 is smaller than the distance between the sleeve 2 76 and the threaded seat 73. Thus, a "lever" mechanism is formed by using the connecting rod to better achieve the quick lifting action.
