Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology, specifically a pulse dust collector with outlet anti-clogging function. Background Technology

[0002] Pulse jet dust collectors are a type of high-efficiency industrial dust removal equipment, widely used in industries such as mining, metallurgy, chemical, and building materials. They are used to treat dust-laden gases and separate dust particles. Their core principle is to periodically clean the filter bags through a pulse jet system to ensure long-term stable filtration efficiency.

[0003] Existing pulse dust collectors have many shortcomings: the ash hopper is prone to blockage of the discharge port due to dust agglomeration or accumulation, leading to frequent shutdowns for cleaning and seriously affecting the continuity of operation; the anti-clogging structure mostly relies on additional motors or hydraulic drives, which increases energy consumption and equipment size, raises manufacturing costs, and the motor is prone to leakage and electric sparks in high dust environments, posing safety hazards and making it unsuitable for flammable and explosive scenarios. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a pulse dust collector with an outlet anti-clogging function, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulse dust collector with an outlet anti-clogging function, comprising a filter chamber, a dust hopper connected to the bottom of the filter chamber, a discharge port at the bottom of the dust hopper, a dust inlet on the side wall of the filter chamber, and a support base fixedly connected to the outer wall of the filter chamber. A compressed air tank and an air distribution chamber are fixedly connected to the top of the filter chamber. A clean air outlet is provided on one side of the air distribution chamber, and a pipe inlet is provided on the side of the air distribution chamber away from the clean air outlet. A blow pipe is fixedly connected to the pipe inlet. A venturi tube is connected to the blow pipe. The output end of the venturi tube passes through the filter chamber and is fitted with a filter bag. The blow pipe is connected to the compressed air tank, and a pulse valve is provided at the input end of the blow pipe.

[0006] As a further embodiment of this utility model: a wind turbine housing is fixedly connected to the air distribution chamber, a wind turbine is rotatably connected inside the wind turbine housing, an air outlet is provided on the wind turbine housing, and the wind turbine housing is connected to the blower pipe.

[0007] As a further embodiment of this utility model: the air distribution chamber is fixedly connected to a bevel gear box, and a driving bevel gear and a driven bevel gear are rotatably connected inside the bevel gear box. The input end of the driving bevel gear passes through the bevel gear box and the impeller housing and is fixedly connected to the impeller coaxially. The output end of the driven bevel gear passes through the bevel gear box and the filter chamber and is fixedly connected to a rotating shaft coaxially. A crushing roller is fixedly connected to the bottom of the rotating shaft.

[0008] As a further embodiment of this utility model: the driving bevel gear meshes with the driven bevel gear.

[0009] As a further embodiment of this utility model: a pulse controller is fixedly connected to the outside of the filter chamber, and the pulse controller is electrically connected to the pulse valve.

[0010] As a further embodiment of this utility model: the top of the filter chamber is provided with multiple ventilation holes, and a dust baffle is fixedly connected inside the filter chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The high-pressure airflow from the compressed air tank drives the impeller to rotate and generate a large torque. Combined with the bevel gear transmission mechanism, the rotating shaft and the crushing roller, a linkage anti-clogging structure is formed. This structure can not only stir the dust accumulated in the ash hopper, but also break up the clumps of dust. This prevents the clogging problem at the bottom outlet of the ash hopper caused by dust clumps or accumulation from the root, ensuring smooth discharge, reducing equipment downtime caused by material blockage, and improving the continuity of operation. 2. The high-pressure airflow driving the impeller comes directly from the device's own compressed air tank and shares the air source with the pulse cleaning system. There is no need to configure additional drive components such as motors and hydraulic systems. This saves energy consumption of independent power sources, simplifies the equipment structure, reduces equipment size and manufacturing costs, and avoids safety hazards caused by motor leakage and electric sparks in ash hopper areas with high dust concentrations. It is especially suitable for industrial scenarios with flammable and explosive materials or high dust sensitivity, and significantly improves safety. Attached Figure Description

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: A pulse dust collector with outlet anti-clogging function includes a filter chamber 1, a dust hopper 2 connected to the bottom of the filter chamber 1, a discharge port 3 at the bottom of the dust hopper 2, a dust inlet 4 on the side wall of the filter chamber 1, and a support base 5 fixedly connected to the outer wall of the filter chamber 1. The top of the filter chamber 1 is fixedly connected to a compressed air tank 6 and an air distribution chamber 7. A clean air outlet 8 is provided on one side of the air distribution chamber 7, and a pipe inlet is provided on the side of the air distribution chamber 7 away from the clean air outlet 8. A blow pipe 9 is fixedly connected to the pipe inlet. A venturi tube 10 is connected to the blow pipe 9. The output end of the venturi tube 10 passes through the filter chamber 1 and is fitted with a filter bag 11. The blow pipe 9 is connected to the compressed air tank 6. A pulse valve 12 is provided on the input end of the blow pipe 9. Specifically, dusty gas enters through dust inlet 4, and dust adheres to the surface of filter bag 11, which purifies the gas. When the dust adhering to the surface of filter bag 11 reaches a certain thickness and affects the filtration efficiency, pulse controller 18 controls pulse valve 12 to open according to a preset program. At this time, high-pressure compressed air in compressed air tank 6 is quickly ejected through blowpipe 9. Through the guiding effect of venturi tube 10, a high-speed airflow is formed and rushes into the interior of filter bag 11 in the opposite direction. Filter bag 11 expands and vibrates rapidly under the impact of high-pressure airflow, and the dust adhering to the surface is shaken off and falls into the dust hopper 2 below after leaving filter bag 11. The air distribution chamber 7 is fixedly connected to the impeller housing 13, the impeller housing 14 is rotatably connected to the impeller housing 13, the impeller housing 13 is provided with an air outlet, and the impeller housing 13 is connected to the blow pipe 9. Specifically, during pulse cleaning, the high-pressure airflow ejected from the blowpipe 9 will simultaneously enter the impeller housing 13, directly impacting the impeller 14 to make it rotate at high speed. The air distribution chamber 7 is fixedly connected to a bevel gear box 15. A driving bevel gear 16 and a driven bevel gear 17 are rotatably connected inside the bevel gear box 15. The input end of the driving bevel gear 16 passes through the bevel gear box 15 and the impeller housing 13 and is fixedly connected to the impeller 14 on the same axis. The output end of the driven bevel gear 17 passes through the bevel gear box 15 and the filter chamber 1 and is fixedly connected to a rotating shaft on the same axis. A crushing roller 20 is fixedly connected to the bottom of the rotating shaft. The driving bevel gear 16 and the driven bevel gear 17 mesh with each other. Specifically, the rotation of the impeller 14 drives the coaxially fixed driving bevel gear 16 to rotate within the bevel gear box 15. Since the driving bevel gear 16 meshes with the driven bevel gear 17, the power is transmitted to the driven bevel gear 17, which in turn drives the coaxially fixed shaft of the driven bevel gear 17 to rotate. The crushing roller 20 at the bottom of the shaft rotates synchronously with the shaft, continuously stirring the dust accumulated in the ash hopper 2, and crushing any agglomerated dust that may form. This prevents dust from accumulating and caking at the bottom of the ash hopper 2 and blocking the discharge port 3, ensuring that the dust can smoothly gather and be discharged from the discharge port 3.

[0016] A pulse controller 18 is fixedly connected to the outside of the filter chamber 1. The pulse controller 18 is electrically connected to the pulse valve 12. Multiple air vents are opened on the top of the filter chamber 1. A dust baffle 19 is fixedly connected inside the filter chamber 1. Specifically, when dust-laden gas enters the filter chamber 1, the dust baffle 19 acts as a buffer and guide for the high-speed dust. Larger dust particles fall into the dust hopper 2 immediately, while smaller particles are adsorbed onto the filter bag 11. Clean air enters the air distribution chamber 7 through the vent holes and is finally discharged from the clean air outlet 8.

[0017] The working principle of this utility model is as follows: First, when dust-laden gas enters the filter chamber 1 from the dust inlet 4, the dust baffle 19 will buffer and guide the high-speed dust. Larger dust particles will fall into the dust hopper 2 immediately, while smaller particles will be adsorbed onto the filter bag 11, thus purifying the gas. Secondly, when the dust adhering to the surface of the filter bag 11 reaches a certain thickness and affects the filtration efficiency, the pulse controller 18 will control the pulse valve 12 to open according to the preset program. At this time, the high-pressure compressed air in the compressed air tank 6 is quickly ejected through the blow pipe 9. Through the guiding effect of the venturi tube 10, a high-speed airflow is formed and rushes into the interior of the filter bag 11 in the opposite direction. The filter bag 11 expands and vibrates rapidly under the impact of the high-pressure airflow, and the dust adhering to the surface is shaken off and falls into the ash hopper 2 below after leaving the filter bag 11. While pulse cleaning is in progress, the high-pressure airflow ejected from the blowpipe 9 will simultaneously enter the impeller housing 13, directly impacting the impeller 14 and causing it to rotate at high speed. The rotation of the impeller 14 drives the coaxially fixed active bevel gear 16 to rotate in the bevel gear box 15. Since the active bevel gear 16 meshes with the driven bevel gear 17, the power is transmitted to the driven bevel gear 17, which in turn drives the coaxially fixed shaft of the driven bevel gear 17 to rotate. The crushing roller 20 at the bottom of the shaft rotates synchronously with the shaft, continuously stirring the dust accumulated in the ash hopper 2, and at the same time crushing any agglomerated dust that may be formed, preventing dust from accumulating and caking at the bottom of the ash hopper 2 and blocking the discharge port 3, ensuring that the dust can smoothly gather and be discharged from the discharge port 3. Finally, the clean air enters the air distribution chamber 7 through the vent and is then discharged from the clean air outlet 8.

[0018] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
