Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: it uses a cutter to cut the fibrous dirt to prevent it from winding around the impeller, but even after cutting, all the dirt must pass through the impeller, and if the cutting is not thorough, the impeller still has the risk of winding

Embodiment 1

[0033] An anti-winding mechanism for an intelligent sewage pump, such as figure 1 , 2 , 3, including a filter part 1, the filter part 1 is welded by the swirl tube 8 and the filter tube 9 using laser seamless welding technology, the inside of the filter tube 9 is provided with a filter assembly 14, the filter Component 14 comprises filter plate 16 and sealing frame 25, and described filter plate 16 and sealing frame 25 axial place inwalls are welded with same slide bar 21, and slide bar 21 is slidably connected on the inwall of filter tube 9, and the other of slide bar 21 One side outer wall is fixed with limiting plate 20 by bolt, and the outer wall of slide bar 21 is sheathed with spring 19, and one side inner wall of filter tube 9 is provided with uniform permeable hole 2 18, and the outer wall of sealing frame 25 is integrally formed with permeable hole 2 The sealing protrusion 24 corresponding to the position 18, the inner wall of the filter plate 16 is provided with the...

Embodiment 2

[0036] An anti-winding mechanism for an intelligent sewage pump, such as figure 2 As shown, in order to solve the problem of flow direction; this embodiment makes the following improvements on the basis of embodiment 1: the inner wall of the swirl tube 8 is fixed with a helical blade 15 .

[0037] When this embodiment is in use, when the water flow enters, the fibrous dirt is almost parallel to the direction of the water flow, that is, the axial direction of the pipeline, so it is easy to enter from the second permeable hole 18, and the device is provided with a helical blade 15, so that the water flow from When flowing in the swirl tube 8, it will form a swirl shape to ensure that the fibrous dirt can be preliminarily filtered by the side wall of the filter tube 9, further improving its filtering effect and preventing the dirt from entering the sewage pump.

Embodiment 3

[0039] An anti-winding mechanism for an intelligent sewage pump, such as figure 1 , 4 , 5, in order to further solve the winding problem; this embodiment makes the following improvements on the basis of embodiment 2: the outer wall of one side of the filter part 1 is welded with a flange-2, and the outer wall of one side of the flange-2 passes through The connecting bolt 6 is connected with the flange 2 4, and the outer wall of the connecting bolt 6 is connected with the fastening nut 7 through threads, and a gasket 3 is arranged between the flange 1 2 and the flange 2 4, and the outer wall of one side of the flange 2 4 is welded There is a cutting part 5, the cutting part 5 is welded by the power pipe 10 and the cutting pipe 11 by seamless laser welding technology, the diameter of the power pipe 10 is smaller than the diameter of the cutting pipe 11, and one side of the cutting pipe 11 The outer wall is welded with a flange three 12, and the inner wall of the cutting pipe 11...

Abstract

The invention discloses an anti-winding mechanism for an intelligent sewage pump, relates to the technical field of water pumps, and aims to solve the problem that sewage enters a sewage pump and winds around an impeller of the sewage pump. The anti-winding mechanism specifically comprises a filtering part; the filtering part is formed by welding a rotational flow pipe and a filtering pipe througha laser seamless welding technology; a filtering assembly is arranged in the filtering pipe and comprises a filtering plate and a sealing frame; the same sliding rod is welded to the inner wall of the axis of the filtering plate and the inner wall of the axis of the sealing frame; the sliding rod is slidably connected to the inner wall of the filtering pipe; a limiting plate is fixed to the outerwall of the other side of the sliding rod through a bolt; the outer wall of the sliding rod is sleeved with a spring; uniform second water permeable holes are formed in the inner wall of one side ofthe filtering pipe; sealing protrusions corresponding to the second water permeable holes in position are integrally formed on the outer wall of the sealing frame; and first water permeable holes staggered with the second water permeable holes are formed in the inner wall of the filtering plate. With the anti-winding mechanism, fibrous dirt cannot enter the sewage pump to wind around the impeller,and the service life of the sewage pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to an anti-winding mechanism for an intelligent sewage pump. Background technique [0002] In industrial production, submersible pumps are widely used in various industries because they can meet many special purposes. The structure of submersible pumps is also being continuously improved. All kinds of scum, plastic products and other fibers such as cotton yarn, hemp rope, rags, etc., or other similar substances, these impurities directly enter the submersible pump, which will easily lead to unsmooth sewage discharge, affect the normal operation of the submersible pump, and cause impeller wear , Impurities will also wrap around the impeller, causing damage to the motor, reducing the working efficiency of the submersible pump and shortening the service life. [0003] After searching, the Chinese patent publication number is CN106438379A, which discloses an anti-clogging and anti-...
