Description

Technical Field

[0001] The present invention relates to the technical field of bottom-drawn silo pumps, and in particular to an anti-clogging bottom-drawn silo pump. Background Art

[0002] The bottom-draw silo pump is a conveying equipment that attracts powder or granular materials through vacuum. Its working principle is to attract the materials to be transported into the pump through negative pressure, and then transport them to the designated location through the pipeline. The bottom-draw silo pump generates vacuum attraction through a high-power motor to attract the materials to be transported into the pump. After the material enters the pump, it is transported to the designated location through the pipeline, realizing the material transportation process. This transportation method is efficient and convenient, and is particularly suitable for the transportation of powder materials such as cement, lime, flour, sawdust, etc. At present, due to the large volume of the silo itself, when there are more powdery materials inside the silo, the materials at the bottom of the silo are under great pressure. Long-term accumulation can easily cause the powdery materials to form arches and block the discharge port, which can easily affect the discharge of the silo pump. Therefore, it is necessary to design an anti-blocking bottom-draw silo pump to solve the problem. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an anti-clogging down-drawing silo pump, which overcomes the deficiencies in the prior art and aims to solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-clogging down-drawing silo pump, comprising a base, a pillar fixedly installed on the top of the base, and a lower silo pump connected to the top of the pillar, an upper silo pump fixedly installed on the top of the lower silo pump, and an injection pipe and a discharge pipe connected to both sides of the upper silo pump, a feed hopper is arranged on the top of the upper silo pump, and a sealing valve is connected between the upper silo pump and the feed hopper, a gasification plate is fixedly installed in the upper silo pump, and an air supply pipe is connected to the bottom of the lower silo pump; The bottom inner wall of the lower warehouse pump is rotatably connected with a connecting frame, and the bottom of the connecting frame is communicated with the air supply pipe through the lower warehouse pump, a stirring pipe is fixedly installed on the top of the connecting frame, the stirring pipe is rotatably connected with the injection pipe and the gasification plate respectively, and the two ends of the stirring pipe are connected with stirring frames, a plurality of air nozzles are connected and installed on the top of the connecting frame, a rotating frame is connected and installed on the bottom of the connecting frame, a driving motor is fixedly installed on the bottom of the lower warehouse pump, and the output shaft of the driving motor is connected with a driving gear through the lower warehouse pump.

[0005] As a preferred technical solution of the present invention, the gasification plate adopts an inclined structure design, and one end of the gasification plate is flush with the lower end of the discharge pipe, which can increase fluidity and avoid material accumulation in one place.

[0006] As a preferred technical solution of the present invention, the stirring tube is connected to the air supply tube, and a plurality of exhaust holes are opened at the lower end of the stirring tube, which can accelerate the stirring efficiency of the material through the fluidity of the gas, and can apply pressure from the upper warehouse pump position to facilitate the discharge of the material.

[0007] As a preferred technical solution of the present invention, the cross-section of the rotating frame adopts an L-shaped structural design to ensure the stability of the rotating frame during rotation, and the inner side is meshed with the driving gear and is provided with a gear groove adapted to the driving gear, so that the driving gear is used to control the rotation of the rotating frame.

[0008] As a preferred technical solution of the present invention, a central tube is provided in the injection tube, and the central tube is located outside the stirring tube to prevent gas from leaking from the connection between the injection tube and the stirring tube. The central tube is located on one side of the discharge pipe and is connected to an injection valve, and a plurality of through holes are provided on the outside of the stirring tube, so that gas can be discharged while rotating, thereby increasing the air pressure.

[0009] As a preferred technical solution of the present invention, the injection pipe is connected to the branch pipes on both sides of the central pipe, so that the airflow blocked by the central pipe can flow through the branch pipe to avoid a reduction in the flow rate of gas.

[0010] Beneficial effects of the present invention: The present invention guides the airflow by designing the injection pipe so that it will not diffuse in other directions, thereby accelerating the discharge efficiency, and supports the material by arranging a gasification plate inside, and can inject gas through the air supply pipe, and discharge it through the air nozzle and use the gasification plate to divert the flow to give the material an upward force, thereby avoiding material accumulation, so that the material can be better discharged into the discharge pipe by the air flow in the injection pipe. Compared with the ordinary down-drawn warehouse pump, the discharge pipe is not arranged at the bottom but at one side, which can effectively avoid the blockage of the discharge port, and the stirring pipe can accelerate the stirring efficiency and apply pressure through the gas in the air supply pipe while stirring the material with the stirring frame, and cooperate with the injection pipe and the air nozzle to squeeze the material out from three directions by air pressure, thereby completing the discharge, greatly reducing the possibility of material blockage, and because the driving motor for controlling the stirring pipe is arranged at the bottom, more space is given to the upper part, and more material can be injected through the feed hopper, thereby accelerating the feeding efficiency and facilitating better discharge work.
