[0037] Reference Figures 1-5For an embodiment of the utility model, propose a kind of vacuum pump feeding system with boost cleaning mechanism, including tank body 1, air inlet pipe 5 and discharge pipe 3, further include: air inlet branch pipe 6 one end is communicated with the inside of tank body 1, other end is communicated with air inlet pipe 5;Annular pipe 8 is set on the inner wall of tank body 1, annular pipe 8 is communicated with air inlet branch pipe 6;Jet pipe 9 has several, several jet pipe 9 is spaced apart on annular pipe 8, and several jet pipe 9 all are located annular pipe 8 far from air inlet branch pipe 6 side.

[0038] In the above scheme, tank body 1 is made of metal material, air inlet pipe 5 and discharge pipe 3 are connected to corresponding gas source and material receiving place respectively.Air inlet branch pipe 6 is metal pipe, one end passes through the top of tank body 1 and is communicated with the inside of tank body 1, other end is connected with air inlet pipe 5.Annular pipe 8 is annular metal pipe, is welded on the inner wall of tank body 1, annular pipe 8 is communicated with air inlet branch pipe 6.Jet pipe 9 adopts several small-bore metal pipes, is evenly spaced and installed on the side of annular pipe 8 far from air inlet branch pipe 6.

[0039] It needs to be explained that sludge vacuum pump further includes feed pipe 4, is set in the middle part of the top surface of tank body 1, further include gas distribution bag 2, gas distribution bag 2 has gas distribution pipe, gas distribution pipe is elbow pipe, gas distribution pipe one end extends into tank body 1, and gas distribution pipe in tank body 1 one end, gas distribution pipe in tank body 1 end opens upward.

[0040] Working process: when cleaning work is carried out after feeding is finished, high-speed airflow enters from air inlet pipe 5, part of airflow enters annular pipe 8 through air inlet branch pipe 6, then is sprayed from jet pipe 9.Due to the airflow sprayed from jet pipe 9 is close to the inner wall of tank body 1, especially close to the bottom of tank body 1, airflow sprayed from jet pipe 9 forms airflow disturbance in tank body 1, and the sludge possibly adhered to the inner wall of tank body 1 is impacted and blown, and a large amount of sludge adhered to the inner wall of tank body 1 is cleaned.

[0041] Specific working steps of sludge vacuum pump are as follows:

[0042] First step, sucking material: high-pressure, high-speed gas enters jet pipe assembly (high vacuum is generated by gas bag in jet pipe assembly) through air inlet pipe 5, and high vacuum is generated in tank body 1, and material is sucked.

[0043] Further specifically, gas flows into gas distribution bag 2 through air inlet pipe 5, and gas distribution bag 2 generates vacuum (limited flow appears the phenomenon of flow velocity increase when passing through the reduced flow section, and the flow velocity is inversely proportional to the flow section, and the increase of flow velocity is accompanied by the reduction of fluid pressure, and low pressure is generated near high-speed flowing fluid, thereby generating adsorption effect);

[0044] When low pressure is generated at the air suction port of gas distribution bag 2, the air in tank body 1 flows to gas distribution bag 2, and flows out with compressed gas, that is, vacuum is generated in tank body 1;

[0045] When the pressure inside the tank 1 is lower than the external pressure, the material will be sucked into the tank 1 under the action of the atmospheric pressure (the suction height of the clean water is 6-8 meters, and the suction depth is different for materials with different specific gravity and viscosity);

[0046] In the second step, the material is discharged: after the material suction process is completed, the compressed gas enters the storage tank 1, and the pressure in the tank 1 will become higher and higher. The material is discharged from the storage tank under the action of high pressure and flows to a remote place along with the compressed gas (the maximum horizontal distance can reach 500-1000 meters, and the conveying distance is different for materials with different specific gravity and viscosity).

[0047] Further, the nozzle 10 has a plurality of nozzles 10, and each nozzle 10 is in communication with the end of the air jet pipe 9.

[0048] In the above scheme, the gas flow flows from the air jet pipe 9 to the nozzle 10, and the nozzle 10 converges and guides the gas flow to be sprayed in a specific direction, thereby enhancing the scouring and cleaning ability of the sludge on the inner wall of the tank 1 and improving the cleaning effect. The nozzle 10 is the end part of the air jet pipe 9, and the nozzle 10 can change the spraying form of the gas flow, for example, through different internal structures, the gas flow can be sprayed in different shapes such as fan shape and cone shape.

[0049] Further, the nozzle 10 is rectangular, and the adjacent nozzles 10 have different inclination angles.

[0050] In the above scheme, the rectangular nozzle 10 is installed at the end of the air jet pipe 9, and the adjacent nozzles 10 have different inclination angles. For example, the first nozzle 10 is at an angle of 30 degrees with the horizontal direction, the adjacent second nozzle 10 is at an angle of 45 degrees with the horizontal direction, and so on.

[0051] Working process: The nozzles 10 with different inclination angles make the directions of the sprayed gas flow different, which can scour the inner wall of the tank 1 from multiple directions, avoid the cleaning dead angle caused by single direction scouring, and comprehensively clean the sludge attached to the inner wall of the tank 1. The shape of the rectangular nozzle 10 provides a relatively large gas outlet area, which is conducive to the stable spraying of the gas flow, and the different inclination angles form a multi-angle gas flow cleaning network in the tank 1.

[0052] Further, the bottom of the tank 1 is in the shape of an inverted cone, and the plurality of nozzles 10 are located above the conical bottom of the tank 1.

[0053] In the above scheme, the bottom of the tank 1 is in the shape of an inverted cone, and the sludge is easily attached to the conical surface. The plurality of nozzles 10 are installed above the conical bottom of the tank 1, for example, at a distance of 3-10 centimeters from the upper surface of the conical bottom, and are evenly distributed on the annular pipe 8.

[0054] Working process: when the gas flow is sprayed from the nozzle 10, due to the conical structure of the bottom of the tank body 1, the gas flow will slide along the conical surface after impacting the sludge in the inner wall of the tank body 1, and the cleaned sludge will be concentrated at the center of the bottom of the tank body 1, which is convenient for subsequent discharge from the tank body 1. The conical shape of the bottom of the tank body 1 cooperates with the position of the nozzle 10, which utilizes the dual action of gravity and gas flow, which is beneficial to the cleaning of the sludge and facilitates the collection and discharge of the sludge.

[0055] Further, the fixed plate 11 has a plurality of fixed plates 11, and the plurality of fixed plates 11 are arranged on the annular pipe 8 in a spaced manner, and the annular pipe 8 is connected with the inner wall of the tank body 1 through the fixed plate 11.

[0056] In the above scheme, a plurality of fixed plates 11 are welded on the annular pipe 8 in a spaced manner, and the fixed plate 11 is made of a metal plate, such as a steel plate. One end of each fixed plate 11 is welded with the annular pipe 8, and the other end is welded with the inner wall of the tank body 1, so as to firmly fix the annular pipe 8 on the inner wall of the tank body 1. During the working process of the vacuum pump, due to the impact and vibration of the gas flow, the annular pipe 8 may shake, and the fixed plate 11 can provide stable support force to ensure the position stability of the annular pipe 8 and the jet pipe 9, so as to ensure the normal jet of the gas flow and the stable operation of the cleaning mechanism.

[0057] Further, the exhaust branch pipe 7 is arranged on the outside of the tank body 1, one end of the exhaust branch pipe 7 is communicated with the side wall of the air inlet branch pipe 6, and the other end of the exhaust branch pipe 7 is communicated with the horizontal section of the discharge pipe 3.

[0058] In the above scheme, the exhaust branch pipe 7 is installed on the outside of the tank body 1, and the exhaust branch pipe 7 is made of a metal pipe, one end of which is communicated with the side wall of the air inlet branch pipe 6 through a tee joint, and the other end is communicated with one side of the horizontal section of the discharge pipe 3. The exhaust branch pipe 7 can also assist the discharge of the discharge pipe 3 to prevent the accumulation of sludge or slurry in the discharge pipe 3.

[0059] Working process: part of the gas flow enters the annular pipe 8 and the jet pipe 9 inside the tank body 1 through the air inlet branch pipe 6, and the other part of the gas flow directly enters the discharge pipe 3 through the exhaust branch pipe 7. This part of the gas flow can play a role in assisting the material conveying in the discharge pipe 3, such as pushing the material to flow more smoothly in the discharge pipe 3, preventing the material from blocking the discharge pipe 3.

[0060] Further, the first valve 601 is arranged on the air inlet branch pipe 6.

[0061] In the above scheme, the first valve 601 is installed on the air inlet branch pipe 6, and the first valve 601 can be a ball valve or a butterfly valve. The valve is installed on one end of the air inlet branch pipe 6 close to the air inlet pipe 5, and is operated by the handle or electric control device of the valve.

[0062] Working process: when the gas flow into the annular pipe 8 inside the tank 1 needs to be adjusted, the first valve 601 can be operated to achieve. For example, when the sludge is less and does not need to be cleaned, the valve can be appropriately closed to reduce the gas flow into the annular pipe 8; and when the sludge is more or needs to be cleaned, the valve is opened to increase the gas flow.

[0063] Further, the second valve 701 is arranged on the exhaust branch pipe 7.

[0064] In the above scheme, the second valve 701 is installed on the exhaust branch pipe 7, and a ball valve or a butterfly valve can also be selected. It is installed at the end of the exhaust branch pipe 7.

[0065] Working process: by controlling the opening of the second valve 701, the gas flow through the exhaust branch pipe 7 into the discharge pipe 3 can be adjusted. For example, when the material in the discharge pipe 3 flows more smoothly, the second valve 701 can be appropriately closed to make more gas flow into the cleaning mechanism inside the tank 1; and when the discharge pipe 3 shows signs of material blockage, the second valve 701 is opened to increase the gas flow of the exhaust branch pipe 7 to dredge the material.

[0066] Further, the air inlet branch pipe 6 is located on one side of the top surface of the tank 1.

[0067] In the above scheme, one end of the air inlet branch pipe 6 is arranged on one side of the top surface of the tank 1, for example, away from the center of the top surface of the tank 1 or close to the center. Such air inlet branch pipe 6 can not affect the feeding of the top feeding port, and at the same time will not occupy too much storage position inside the tank 1.

[0068] Further, the annular pipe 8 has a mounting cylinder 12 at the bottom, and the air jet pipe 9 is arranged on the bottom surface of the annular pipe 8 through the mounting cylinder 12.

[0069] In the above scheme, the mounting cylinder 12 is welded at the bottom of the annular pipe 8, and the mounting cylinder 12 is a hollow metal cylinder. One end of the air jet pipe 9 is inserted into the mounting cylinder 12 and is fixed by welding or threaded connection. The inner diameter of the mounting cylinder 12 matches the outer diameter of the air jet pipe 9 to ensure the tightness and stability of the connection.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the present application can be modified or replaced by the equivalent, without departing from the spirit and scope of the technical scheme of the present application, which should be covered in the scope of the claims of the present application.
