Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic submersible pumps, in particular to an anti-clogging nozzle plate of a pneumatic submersible pump for a mine. Background Art

[0002] The pneumatic submersible pump uses compressed air to pass through the nozzle plate. The design of the nozzle plate allows the compressed air to effectively impact the turbine and make the turbine rotate. The turbine is connected to the pump shaft. When the turbine rotates, it drives the impeller on the pump shaft to rotate at high speed, thereby generating centrifugal force, throwing water from the inside of the pump body to the outlet to achieve the purpose of drainage.

[0003] However, during the use of the submersible pump, the external wind is directly introduced into the submersible pump through the nozzle plate, which leads to blockage inside the submersible pump and causes blockage of the nozzle plate during use; therefore, the present application proposes an anti-blocking nozzle plate for a pneumatic submersible pump for mining.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes an anti-clogging nozzle plate for a pneumatic submersible pump for mining, comprising:

[0022] Nozzle disc, used in pneumatic submersible pump 1;

[0023] A nozzle plate assembly 2 mounted on a pneumatic submersible pump 1; the nozzle plate assembly 2 comprises a nozzle plate body 3 mounted on the pneumatic submersible pump 1, a filter box 4 mounted on the nozzle plate body 3, an air inlet located above a circular mesh plate 14 being provided through the filter box 4; a circular mesh plate 14 is mounted in the filter box 4, the circular mesh plate 14 is made of stainless steel and has a certain thickness, and can support the rotation of the rotating tube 11, and a dustproof net can be attached and fixed on the surface thereof for filtering the air; a mounting frame is fixed on the inner wall of the filter box 4, the circular mesh plate 14 is fixed in the mounting frame, the outer wall of the mounting frame is fixedly connected to the inner wall of the filter box 4, the inner part is circular, and the circular mesh plate 14 is fixed in the inner part of the mounting frame 14;

[0024] A coaxial rotating tube 11 is provided through the circular mesh plate 14, a motor 7 is installed on the upper end of the filter box 4, a short rod 10 is fixed to the output end of the motor 7, and a transmission wheel 8 is installed on the short rod 10 and the rotating tube 11, and the two transmission wheels 8 are connected by a belt 9;

[0025] Two cleaning brushes 16 in the shape of arc plates located on the upper and lower sides of the circular mesh plate 14 and abutting against the circular mesh plate 14 are fixed to the rotating tube 11. A dust suction pipe 17 connected to the rotating tube 11 is fixed through the cleaning brush 16 on the upper side. The dust suction pipe 17 is penetrated by a plurality of dust suction holes opposite to the circular mesh plate 14. The dust suction pipe 17 is connected to the rotating tube 11 through a curved pipe 15. The width and length of the cleaning brush 16 are greater than the length and width of the dust suction pipe 17, so the dust suction pipe 17 can be covered.

[0026] A negative pressure mechanism for generating negative pressure at the dust suction hole is installed on the filter box 4, and the negative pressure mechanism includes a dust suction box 5 fixed on the upper end of the filter box 4, and a negative pressure fan 6 is installed on the dust suction box 5. The air inlet end of the negative pressure fan 6 is connected to the dust suction box 5, and the dust suction box 5 is connected to the rotating tube 11 through a connecting pipe 12. A dust collecting net is installed in the dust suction box 5, and the connecting pipe 12 and the negative pressure fan 6 are located on both sides of the dust collecting net. A rotating joint 13 is installed on the upper end of the rotating tube 11, and the connecting pipe 12 is connected to the rotating joint 13.

[0027] The detailed working process of the utility model is as follows:

[0028] When the pneumatic submersible pump 1 is working, the external air enters the filter box 4 through the air inlet, and after being filtered by the circular mesh plate 14, the air enters the pneumatic submersible pump 1 through the nozzle plate body 3. The circular mesh plate 14 can filter the air to avoid clogging the nozzle plate body 3.

[0029] During use or when the circular mesh plate 14 needs to be cleaned, the motor 7 and the negative pressure fan 6 are started, and the motor 7 drives the short rod 10 to rotate. Under the transmission of the transmission wheel 8 and the belt 9, the rotating tube 11 can be rotated, and the rotation of the rotating tube 11 drives the two cleaning brushes 16 and the dust suction tube 17 to rotate. The circular mesh plate 14 can be cleaned by the cleaning brush 16, and the bristles of the cleaning brush 16 on the lower side can push the dust onto the circular mesh plate 14 from the bottom, so as to prevent the circular mesh plate 14 from being blocked and cleaned;

[0030] The negative pressure fan 6 works to exhaust the air in the dust box 5, and the air enters the dust box 5 through the dust suction hole, the dust suction pipe 17, the bent pipe 15, the rotating pipe 11 and the connecting pipe 12, so that negative pressure is generated at the dust suction hole, so that the dust generated by cleaning can be sucked into the dust box 5 and finally filtered through the dust collecting net, thus completing the cleaning of the circular mesh plate 14; wherein, since the width and length of the cleaning brush 16 are both greater than the length and width of the dust suction pipe 17, the dust suction pipe 17 can be covered, so when the air passes through the circular mesh plate 14, the cleaning brush 16 blocks the dust suction hole of the dust suction pipe 17, and since the external air passes through the circular mesh plate 14, the direction of dust suction is opposite to the direction of air passing through the circular mesh plate 14, and the dust suction hole of the dust suction pipe 17 is blocked by the cleaning brush 16, it can be prevented that the air affects the dust suction work, so that the circular mesh plate 14 can be cleaned more effectively.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
