Description

Technical Field

[0001] This utility model belongs to the field of pneumatic sludge pump technology, and more specifically relates to a structural component of a noise-reducing, high-suction pneumatic sludge pump. Background Technology

[0002] The mine pneumatic sludge and sewage pump comprises a tank with an inlet pipe and a discharge pipe at both ends. Both the inlet and discharge pipes have integrated bidirectional knife valves, which are connected to pneumatic actuators. These actuators are connected to a pneumatic control assembly to control and switch between the actuators, achieving orderly switching between suction and discharge during pump operation. A vacuum suction assembly is connected to the outside of the tank. Designed based on the Venturi effect principle, the vacuum suction assembly mainly consists of a nozzle that contracts before expanding, a negative pressure chamber, and an expansion pipe. The vacuum suction assembly has an air inlet pipe and an air outlet pipe, with a control valve on the air inlet pipe.

[0003] The pump is driven by compressed air. When the pneumatic control component cycles through the operation of the cylinder and the knife valve, the suction and discharge processes of the unit are completed. During suction, the venturi effect generates negative pressure. Since the knife valve at the pump discharge end is closed, the negative pressure inside the pump draws the sludge from the pump inlet into the negative pressure chamber. At the same time, high-pressure gas is discharged from the exhaust pipe of the vacuum suction component. During discharge, the knife valve at the pump inlet is closed, and the exhaust pipe of the vacuum suction component is closed. At this time, high-pressure gas enters the negative pressure chamber through the negative pressure pipe with a venturi structure, forcing the sludge in the negative pressure chamber out through the discharge pipe.

[0004] Although the exhaust pipe of the vacuum suction component is connected to a silencer, in actual application, it was found that the noise of the sludge pump was still very loud even with the silencer installed. Utility Model Content

[0005] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a structural component for a noise-reducing, high-suction pneumatic sludge pump;

[0006] The first technical problem to be solved was that even with a silencer, the compressed air from the pneumatic dredging pump was still very noisy after being discharged through the exhaust pipe via the venturi structure of the vacuum suction component.

[0007] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the structural components of the noise-reducing high-suction pneumatic dredging pump are arranged between the pump's vacuum suction component and the pump's discharge port, characterized in that: it includes a variable diameter expansion port joint, a noise-reducing connecting pipe, and a Y-type tee pipe.

[0008] One end of the variable diameter expansion port connector is detachably connected to the exhaust pipe of the exhaust end of the vacuum suction assembly; the other end of the variable diameter expansion port connector is detachably connected to the noise reduction connecting pipe; the noise reduction connecting pipe is connected to the pump discharge port and the discharge pipe respectively through a Y-shaped tee pipe.

[0009] Furthermore, the flare cone angle of the variable diameter expansion joint is 20~60 degrees.

[0010] Furthermore, the outer diameter of the noise-reducing connecting pipe is adapted to the variable diameter expansion port connector, and the inner diameter of the noise-reducing connecting pipe is larger than the inner diameter of the exhaust pipe.

[0011] Furthermore, the noise reduction connecting pipe is equipped with a valve for limiting the unidirectional flow of airflow.

[0012] Furthermore, the valve is a one-way valve or a shut-off valve.

[0013] Furthermore, a pneumatic valve is installed on the exhaust pipe.

[0014] The beneficial effects of this utility model are:

[0015] One advantage of this invention is that a structural component of a noise-reducing, high-suction pneumatic sludge cleaning pump is set between the vacuum suction assembly of the pump and the pump discharge port. This component can treat the noisy gas discharged from the vacuum suction assembly, and has a good noise reduction effect compared with traditional silencers.

[0016] One advantage of this invention is that the expansion cone angle of the variable diameter expansion port joint in the structural components of the noise-reducing, high-suction pneumatic sludge pump is 20~60 degrees. The gas is effectively released in the noise-reducing connecting pipe, and with the help of the flowing sludge in the discharge pipe with a long conveying distance, the noise generated during the operation of the pneumatic sludge pump is greatly reduced, and the working efficiency is higher.

[0022] The specific embodiment of this utility model: the structural components of the noise-reducing, high-suction pneumatic sludge pump.

[0023] The improvement of this utility model is that a reducing expansion joint 3, a noise reduction connecting pipe 2, and a Y-type tee pipe 1 are provided between the vacuum suction assembly 8 of the pump and the discharge port 7 of the pump.

[0024] One end of the variable diameter expansion port joint 3 is detachably connected to the exhaust pipe 5 at the exhaust end of the vacuum suction assembly 8; the other end of the variable diameter expansion port joint 3 is detachably connected to the noise reduction connecting pipe 2; the noise reduction connecting pipe 2 is connected to the pump discharge port 7 and the discharge pipe 6 respectively through the Y-type tee pipe 1.

[0025] Preferably, the flare cone angle of the variable diameter expansion joint 3 is 20~60 degrees.

[0026] Furthermore, the outer diameter of the noise reduction connecting pipe 2 is adapted to the diameter expansion port joint 3, and the inner diameter of the noise reduction connecting pipe 2 is larger than the inner diameter of the exhaust pipe 5.

[0027] As a preferred embodiment of this utility model, the noise reduction connecting pipe 2 is provided with a valve for limiting the unidirectional flow of airflow.

[0028] Furthermore, the valve is a one-way valve or a shut-off valve.

[0029] Furthermore, a pneumatic valve 4 is provided on the exhaust pipe 5.

[0030] It should be noted that this utility model is a structural component of a noise-reducing, high-suction pneumatic sludge pump. In specific operation...

[0031] 1. The working principle of the pneumatic sludge pump is detailed in the technical background and will not be repeated here. The problem solved by this utility model is that the compressed air of the pneumatic sludge pump is discharged through the exhaust pipe by the venturi structure of the vacuum suction component, and the noise of the sludge pump is still very loud even if a silencer is installed.

[0032] During the material suction stage, the venturi structure of the high-pressure gas vacuum suction component is discharged through the exhaust pipe 5 and enters the noise reduction connecting pipe 2 through the variable diameter expansion port connector 3. The variable diameter expansion port connector 3 has an expansion cone angle.

[0033] The outer diameter of the noise-reducing connecting pipe 2 is adapted to the diameter-adjusting expansion joint 3, and the inner diameter of the noise-reducing connecting pipe 2 is larger than the inner diameter of the exhaust pipe 5; in this way, the high-pressure gas has an effective space for release within the noise-reducing connecting pipe 2, which reduces the noise generated by the high-pressure, high-speed gas to a certain extent.

[0034] At the same time, the gas with reduced noise enters the discharge pipe 6. The long-distance discharge pipe contains flowing sludge, which greatly reduces the noise generated during the operation of the pneumatic sludge pump and makes the work more efficient.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
