Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying material sealing pump technology, and in particular to a powder pneumatic conveying material sealing pump. Background Technology

[0002] Powder pneumatic conveying technology is mainly used in chemical, building materials, and grain processing industries. It uses the pressure difference formed by airflow in the pipeline to achieve continuous conveying of powdery materials (such as cement, flour, coal powder, etc.). It features high conveying efficiency, low pollution, and long-distance transmission, and is an important method of material transfer in industrial production.

[0003] Existing pneumatic conveying pumps for powders mostly adopt traditional pump body structures, mainly consisting of an air inlet device, a sealed cavity, a discharge pipe, and a drive system. They rely on the kinetic energy of compressed air or centrifugal fans to push powder materials from the inlet to the outlet, and are suitable for material conveying operations under normal working conditions.

[0004] When existing material conveying pumps operate under high load for extended periods, the friction between the drive motor and the airflow inside the pump body can generate a large amount of heat. This heat accumulation can lead to problems such as motor overheating and aging of seals. This not only affects the stability of conveying efficiency but can also cause powder materials to clump together and equipment failures due to high temperatures, making it difficult to meet the reliable operation requirements of continuous production or high-temperature conditions. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a powder pneumatic conveying material sealing pump, which aims to improve the problem of poor heat dissipation during high-load operation in the prior art, which causes equipment failure and affects production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A powder pneumatic conveying pump includes a pipe, a pump body, and a housing. A heat dissipation component is installed on the outside of the housing, and a cleaning component is installed inside the pipe.

[0008] The heat dissipation assembly includes a housing, with mounting holes inside the housing. The housing is fixedly connected to the outside of the mounting holes, and two brackets are fixedly connected inside the housing. A fan and a cooling fin are respectively installed inside the two brackets.

[0009] As a further description of the above technical solution:

[0010] The cleaning assembly includes a motor, which is fixedly connected to the outside of the pipe. A bevel gear one is fixedly connected to the output end of the motor. A mounting box is rotatably connected to the outside of the bevel gear one. A bevel gear two is rotatably connected inside the mounting box. The bevel gear one and the bevel gear two are interlocked with each other. A rotating shaft is rotatably connected inside the bevel gear two. A scraper is fixedly connected to one end of the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] A ventilation mesh is fixedly connected to the outer side of the outer casing, and the ventilation mesh is located on the outer side of the cooling element;

[0013] As a further description of the above technical solution:

[0014] Multiple fixing brackets are fixedly connected to the outside of the mounting box, and the other end of the multiple fixing brackets is fixedly connected to the inner wall of the pipe.

[0015] As a further description of the above technical solution:

[0016] A protective box is fixedly connected to the outside of the pipe, and the motor is installed inside the protective box;

[0017] As a further description of the above technical solution:

[0018] A solenoid valve is installed on the outside of the pipe, and the solenoid valve is located on the outside.

[0019] As a further description of the above technical solution:

[0020] A filter screen is fixedly connected inside the pipe, and the filter screen is located outside the scraper.

[0021] As a further description of the above technical solution:

[0022] A heat dissipation mesh is fixedly connected to the outside of the box.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, after prolonged operation, the pump body generates a large amount of heat. At this time, the cooling fins are activated to quickly cool the air, and then the fan is activated to draw the cold air out and spray it into the housing, achieving rapid cooling and heat dissipation, protecting the pump body from damage and extending its service life.

[0025] 2. In this invention, after prolonged operation, a large amount of dust accumulates on the filter screen surface due to electrostatic adsorption, leading to a decrease in the pump's blowing efficiency. At this time, starting the motor causes the bevel gear to rotate, which in turn drives the rotating shaft and scraper to quickly clean the dust adsorbed on the filter screen, thus improving work efficiency.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a powder pneumatic conveying material sealing pump, including a pipe 1, a pump body 20 and a housing 11. A heat dissipation component is installed on the outside of the housing 11, and a cleaning component is installed inside the pipe 1.

[0035] The heat dissipation assembly includes a housing 13 made of stainless steel, which is fixedly connected to the outside of the mounting hole 12 by welding to ensure a firm connection and good sealing. The mounting hole 12 is opened inside the housing 11, and the housing 13 is fixedly connected to the outside of the mounting hole 12. Two brackets 16 are fixedly connected inside the housing 13. The brackets 16 are provided with circular grooves around their perimeter to allow for air circulation and higher heat dissipation efficiency. A fan 15 and a cooling plate 17 are respectively installed inside the two brackets 16. When the cooling plate 17 is turned on, the air is quickly cooled. Then, the fan 15 is turned on to draw out the cold air generated by the cooling plate 17 and spray it into the housing 11 to achieve the goal of rapid cooling and heat dissipation, protect the pump body 20 from damage, and extend its service life. A ventilation mesh 18 is fixedly connected to the outside of the housing 13. The ventilation mesh 18 is made of metal wire mesh, which can ensure smooth air circulation and prevent foreign objects from entering the inside of the housing 13 and damaging the cooling plate 17 and fan 15. At the same time, it dissipates the heat generated by the cooling plate 17. The ventilation mesh 18 is located outside the cooling plate 17.

[0036] Reference Figure 1 and Figure 3 The cleaning assembly includes a motor 2, which is fixedly connected to the outside of the pipe 1. A bevel gear 5 is fixedly connected to the output end of the motor 2. A mounting box 4 is rotatably connected to the outside of the bevel gear 5. The mounting box 4 is made of plastic and protects the internal bevel gears 5 and 6. The bevel gear 6 is rotatably connected inside the mounting box 4, and the bevel gears 5 and 6 interlock. A rotating shaft 8 is rotatably connected inside the bevel gear 6. A scraper 9 is fixedly connected to one end of the rotating shaft 8. The scraper 9, made of wear-resistant rubber, is arc-shaped and can tightly adhere to the filter screen. On the surface of the 10th mounting box 4, multiple mounting brackets 7 are fixedly connected to the outside. The other end of the mounting brackets 7 is fixedly connected to the inner wall of the pipe 1. The mounting brackets 7 are made of stainless steel and are connected to the mounting box 4 by welding. The other end of the mounting brackets 7 is fixedly connected to the inner wall of the pipe 1 by bolts to ensure that the mounting box 4 is securely installed and to ensure the stability of the cleaning component during operation. A protective box 3 is fixedly connected to the outside of the pipe 1. The motor 2 is installed inside the protective box 3. The protective box 3 can effectively prevent the motor 2 from being corroded by external dust, water vapor and other factors, and extend the service life of the motor 2.

[0037] Reference Figure 1 , Figure 2 and Figure 5A solenoid valve 19 is installed on the outside of pipe 1. The solenoid valve includes a solenoid coil generating a magnetic field when energized, an armature driven by magnetic force to move, a valve core opening and closing the channel under the action of the armature, a valve body providing fluid flow space, and a spring reset mechanism to return the valve core to its original position. This is existing technology and will not be described in detail hereafter. The purpose of setting the solenoid valve 19 is to prevent the pump body 20 from being accidentally opened. The solenoid valve 19 is located on the outside of 4. A filter screen 10 is fixedly connected inside pipe 1. The filter screen 10 is located on the outside of scraper 9. The filter screen 10 is made of stainless steel woven mesh and is located on the outside of scraper 9. It can effectively filter impurities in powder materials and, together with scraper 9, realize the automatic cleaning function. A heat dissipation mesh 14 is fixedly connected to the outside of the box 11.

[0038] Working principle: First, after working for a long time, the pump body 20 generates a lot of heat. At this time, the cooling plate 17 is activated to quickly cool the air. Then, the fan 15 is activated to draw out the cold air generated by the cooling plate 17 and spray it into the interior of the housing 11 to achieve the purpose of rapid cooling and heat dissipation, protect the pump body 20 from damage, and extend its service life.

[0039] Secondly, after working for a long time, due to electrostatic adsorption, a lot of dust accumulates on the surface of the filter screen 10, which reduces the blowing efficiency of the pump body 20. At this time, the motor 2 is started, which makes the bevel gear 5 rotate. The bevel gear 5 drives the bevel gear 6 to rotate, which drives the rotating shaft 8 to rotate. At this time, the scraper 9 rotates, quickly cleaning the dust adsorbed on the filter screen 10 and improving the working efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
