Description

Technical Field

[0001] The utility model relates to the field of buoyancy boxes, in particular to a novel water pump suction pipe filter buoyancy box. Background Art

[0002] Currently, conventional pump suction pipe filters are fixed, facilitating drainage after filtration. However, in mining pits where water is heavily silted, rainwater washes sediment from surrounding areas into the pit, easily burying the suction port of the suction pipe filter and causing blockage. Even at high water levels, the fixed position still draws in a layer of silt, resulting in a high discharge volume, which can damage drainage equipment and cause frequent equipment failures. Therefore, it was necessary to develop a solution to this problem. Utility Model Content

[0003] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a new type of water pump suction pipe filter float, which can effectively solve the problem that the existing fixed filter is always in the mud and sand layer and is easily buried by mud and sand.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A novel water pump suction pipe filter float box includes a filter box and a connecting pipe; one end of the connecting pipe extends into the filter box, and the other end of the connecting pipe extends out of the filter box; the filter box is connected to a float that allows the filter box to be suspended in water.

[0006] Preferably, the connecting pipe includes a straight tube body and a 90° elbow. The straight tube body is vertically arranged, and the lower end of the straight tube body is inserted into the filter box from the top of the filter box and maintains a distance from the inner bottom of the filter box. One end of the 90° elbow is connected to the upper end of the straight tube body, and the other end of the 90° elbow is provided with a flange.

[0007] Preferably, the filter box is made of stainless steel wire mesh.

[0008] Preferably, two round steels are inserted into the upper end of the filter box and connected to a clamp through four rotating rods. The clamp clamps tightly hold the two buoys and are locked by bolts.

[0009] Preferably, the buoy is a cylindrical buoy.

[0010] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0011] By setting up a float, the filter box is suspended in the water and moves with the water level, keeping it suspended in the water. It always follows the change of the liquid level and always sucks in the upper water quality, so that the drainage impurity content is low, which can maintain normal drainage of the equipment and greatly reduce the equipment failure rate, thereby ensuring production safety.

[0023] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the present utility model, including a filter box 10 and a connecting pipe 20.

[0024] The filter box 10 is connected to a float 30 that suspends the filter box 10 in the water. In this embodiment, the filter box 10 uses a stainless steel wire mesh 101. Specifically, the filter box 10 includes an upper steel plate ring 11, a lower steel plate ring 12 and a plurality of support rods 13. The lower steel plate ring 12 is located below the upper steel plate ring 11. The plurality of support rods 13 are connected between the upper steel plate ring 11 and the lower steel plate ring 12 and are arranged in a circumferential manner. The stainless steel wire mesh 101 covers the upper steel plate ring 11, the lower steel plate ring 12 and the plurality of support rods 13. In addition, two round steels 14 are inserted into the upper end of the filter box 10 and are connected to a clamp 16 through four rotating rods 15. The clamp 16 clamps the two floats 30 and is locked by bolts 17. In addition, the float 30 is a cylindrical float.

[0025] One end of the connecting pipe 20 extends into the filter box 10, and the other end of the connecting pipe 20 extends outside the filter box 10. Specifically, the connecting pipe 20 includes a straight pipe body 21 and a 90° elbow 22. The straight pipe body 21 is arranged vertically, and the lower end of the straight pipe body 21 is inserted into the filter box 10 from the top and maintains a distance from the inner bottom of the filter box 10. One end of the 90° elbow 22 is connected to the upper end of the straight pipe body 21, and the other end of the 90° elbow 22 is provided with a flange 23.

[0026] During use, the entire filter box 10 can float on the water surface via two floats 30. To adapt to the drainage of mining pits with a lot of sediment and the easy formation of sediment layers, two cylindrical floats 30 are specially designed to float the entire filter box 10 on the upper layer of water and ensure that the suction port maintains a certain liquid depth at the water surface. Moreover, this liquid depth L can be designed according to the size of the suction port to ensure that the water pump will not drop water due to air intake during operation and be unable to continuously drain water. By providing four rotating rods 15, the filter box 10 sags downward due to its weight. The rotating rods 15 are movable and rotatable. Under the vertical gravity, the floats 30 will be pulled by the four rotating rods 15 and float horizontally on the water surface. The design depth of the suction port is designed through calculation, and the distance from the suction port to the bottom of the filter box 10 is also designed. Even if sediment accumulates in time and the filter box 10 runs aground, the sediment layer will not cover the suction port, maintaining a certain distance to protect the suction port when the pump is stopped. As long as the liquid level is reached, the suction port will automatically move away from the sediment layer and be ready for drainage at any time.

[0027] After the overall installation, the flange 23 is connected to a section of hose (not shown in the figure), and a clamp-type float (not shown in the figure) is installed on the hose near the filter box 10 to maintain the buoyancy of the filter box 10 evenly and without tilting. In this way, the filter box 10 can be kept floating steadily and horizontally on the water surface, and a liquid level linkage control is installed to facilitate the stability of drainage.

[0028] The design focus of the utility model is: by providing a float, the filter box is suspended in the water by using the float, and moves with the water level and remains suspended in the water, always following the changes in the liquid level, and always sucking in the upper layer of water, so that the drainage impurity content is small, which can maintain normal drainage of the equipment and greatly reduce the equipment failure rate, thereby ensuring production safety.

[0029] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
