Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and particularly relates to a bag mounting structure of a pulverizer dust remover for feed production. Background Art

[0002] At present, in feed production, the dust removers matched with pulverizers generally have the following core problems, which seriously affect the production efficiency: Extremely difficult bag replacement: A metal exhaust duct with a diameter of 600mm is welded on the top of the existing dust remover, and I-steel beams are arranged above it, which completely block the top disassembly and assembly passage; the dust remover is not designed with a special bag disassembly and assembly opening, so that the dust removal bag cannot be replaced for a long time, and the air permeability of the bag gradually decreases.

[0003] High structural transformation cost: If the bag is replaced by cutting the top exhaust duct and adjusting the I-steel beams, production must be stopped for transformation, and the transformation cycle is long with high cost, which cannot meet the production demand of feed mills for "low cost and less downtime".

[0004] There is no simple bag mounting solution for dust removers with limited top space in the prior art, and there is an urgent need for a mounting structure that does not need to modify the top structure, can be disassembled and assembled from the existing access opening, and can improve dust removal efficiency. Contents of the Utility Model

[0005] The purpose of the present application is to provide a bag mounting structure of a pulverizer dust remover for feed production, which has the advantage of facilitating bag replacement and solves the problems raised in the background art.

[0006] The bag mounting structure of a pulverizer dust remover for feed production provided by the present application adopts the following technical solution: A bag mounting structure of a pulverizer dust remover for feed production, comprising a dust remover body, a plurality of injection holes are opened at the inner top of the dust remover body, a dust removal bag assembly is installed below each of the injection holes, and a mounting assembly is arranged between the injection hole and the dust removal bag assembly; The dust removal bag assembly comprises a bag body and a top cover fixedly connected to the top end of the bag body, a communication hole is opened on the upper surface of the top cover, the mounting assembly comprises an external thread joint welded on the upper surface of the top cover, a connecting seat is welded on the outer surface of the injection hole, a venturi tube is welded on the inner wall of the connecting seat, an internal thread sleeve is welded on the outer surface of the venturi tube, the internal thread sleeve is in threaded connection with the external thread joint, and the bottom end of the venturi tube is inserted into the inner wall of the communication hole.

[0007] By adopting the above technical solution, the detachable connection between the dust collector bag assembly and the blowhole is achieved through the threaded engagement of the internal threaded sleeve and the external threaded connector in the installation component. No cutting or adjustment of the components on top of the dust collector or the I-beam above is required. Operators can simply reach through the inspection door on the front of the dust collector body to engage or disengage the external threaded connector and the internal threaded sleeve, thus enabling the installation or removal of the bag body. This solves the problem of the dust collector bag assembly being unable to be replaced due to blocked top channels. Simultaneously, the welded engagement of the connecting seat and the venturi tube stably receives the airflow from the blowhole, ensuring smooth airflow through the venturi tube into the dust collector bag assembly without disrupting the original airflow channels of the dust collector, guaranteeing normal operation of the dust removal function. Furthermore, the overall connection structure is based on the existing blowhole and dust collector bag assembly design, eliminating the need for additional complex components on the dust collector body, thus reducing the difficulty and cost of modification.

[0008] Preferably, a first silicone sealing gasket is fixedly connected to the upper surface of the top cover, and the first silicone sealing gasket is sleeved on the outer surface of the external thread connector.

[0009] By adopting the above technical solution, the first silicone sealing gasket is sleeved on the outside of the external threaded joint, which can directly cover the gap between the external threaded joint and the internal threaded sleeve. It can effectively prevent airflow from leaking from these gaps. Since the silicone material has good elasticity and sealing properties, even during long-term use, the first silicone sealing gasket can fill the gaps through its own deformation, avoiding the decrease in dust removal efficiency due to air leakage.

[0010] Preferably, the upper surface of the first silicone sealing gasket abuts against the bottom surface of the internal threaded sleeve.

[0011] By adopting the above technical solution, when the internal threaded sleeve and the external threaded connector are screwed into place, the upper surface of the first silicone sealing gasket is in close contact with the bottom surface of the internal threaded sleeve, which can further enhance the sealing effect. In the contact state, the first silicone sealing gasket can be subjected to the pressure of the internal threaded sleeve, thereby more fully adhering to the upper surface of the top cover and the bottom surface of the internal threaded sleeve, further eliminating the tiny gaps between the two components.

[0012] Preferably, a limiting ring is fixedly connected to the venturi tube segment, and a second silicone sealing gasket is fixedly connected to the bottom surface of the limiting ring.

[0013] By adopting the above technical solution, the limiting ring is fixed on the venturi tube section, which can limit the position of the dust collector bag assembly. When the dust collector bag assembly is connected to the internal threaded sleeve through the external threaded connector, the upper surface of the top cover will contact the second silicone sealing gasket. The limiting ring can limit the screwing depth of the external threaded connector, avoiding excessive stretching of the bag body due to excessive screwing or insufficient sealing due to insufficient screwing. The second silicone sealing gasket is set on the bottom surface of the limiting ring, which can not only avoid hard contact between the limiting ring and the top cover during the limiting process, playing a buffer protection role and preventing damage due to collision, but also further fill the gap between the limiting ring and the top cover, enhancing the sealing performance of the overall structure.

[0014] Preferably, the bottom surface of the second silicone sealing gasket abuts against the upper surface of the top cover.

[0015] By adopting the above technical solution, the bottom surface of the second silicone sealing gasket abuts against the upper surface of the top cover. On the one hand, the elastic deformation of the silicone material can completely fill the gap between the limiting ring and the top cover, preventing dust-laden airflow from entering the area above the limiting ring through the gap during equipment operation. On the other hand, the second silicone sealing gasket in the abutting state can provide a certain support force to the top cover. Combined with the limiting effect of the limiting ring, this ensures that the dust collector bag assembly maintains a stable installation position and a stable dust removal efficiency during equipment operation.

[0016] Preferably, the Venturi tube and the connecting seat are both coaxially arranged with the blow hole, and there is no air leakage at the weld.

[0017] By adopting the above technical solution, the coaxial arrangement of the venturi tube, connecting seat and blow hole can ensure that the airflow from the blow hole can enter the venturi tube in a straight line, avoiding local airflow turbulence or airflow loss caused by airflow direction deviation, so that the airflow can be more evenly distributed inside the venturi tube, and then smoothly enter the filter bag body, improving the filtration efficiency of the filter bag body.

[0018] Preferably, an exhaust pipe module is installed on the top of the dust collector body.

[0019] By adopting the above technical solution, the exhaust pipe module on the top of the dust collector body is used as the exhaust channel, without the need to install new exhaust pipes. This fully utilizes the existing equipment structure, reduces the cost of modification, and does not require any changes to the exhaust pipe module, meeting the feed mill's need for less downtime and lower cost of modification.

[0020] Preferably, an inspection door is installed on the front of the dust collector body, and a base frame is fixedly connected to the bottom of the dust collector body.

[0021] By adopting the above technical solution, the inspection door on the front of the dust collector body provides a convenient passage for the disassembly and assembly of the dust collector bag assembly. The staff only need to open the inspection door to reach into the dust collector body and complete the screwing or unscrewing operation of the external threaded connector and the internal threaded sleeve. The base frame on the bottom of the dust collector body can provide stable support for the entire dust collector.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This invention relates to a dust collector bag installation structure for a feed production crusher. Through the threaded engagement of the internal threaded sleeve and the external threaded connector in the installation assembly, operators can disassemble and assemble the dust collector bag assembly without modifying the exhaust pipe module at the top of the dust collector body or the upper I-beam. They can simply reach through the inspection door on the front of the dust collector body. This solves the problem of blocked top channels preventing bag replacement. Simultaneously, a first silicone sealing gasket is fitted over the external threaded connector and abuts against the internal threaded sleeve, while a second silicone sealing gasket, in conjunction with a limiting ring, fills the gap, providing a double seal to prevent air leakage. The limiting ring also restricts the movement of the dust collector bag assembly, preventing friction and wear between the bag body and the inner wall of the dust collector body. The venturi tube, connecting seat, and blowhole are coaxially arranged to ensure smooth airflow. Furthermore, the overall design relies on existing components, eliminating the need for complex additional structures. This reduces modification and maintenance costs while ensuring stable dust collection efficiency, meeting the needs of feed mills for low cost and minimal downtime. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A baghouse installation structure for a dust collector in a feed production grinder, referring to... Figure 1 , Figure 3 and Figure 4 The dust collector includes a dust collector body 1. Multiple blow holes 4 are provided on the inner top of the dust collector body 1. A dust collector bag assembly 5 is installed below each blow hole 4. An installation assembly 6 is provided between the blow holes 4 and the dust collector bag assembly 5. The dust collector bag assembly 5 includes a bag body 501 and a top cover 502 fixedly connected to the top of the bag body 501. A connecting hole 503 is provided on the upper surface of the top cover 502. The installation assembly 6 includes an external threaded connector 601 welded to the upper surface of the top cover 502. A connecting seat 604 is welded to the outer surface of the blow holes 4. A venturi tube 603 is welded to the inner wall of the connecting seat 604. An internal threaded sleeve 605 is welded to the outer surface of the venturi tube 603. The internal threaded sleeve 605 is threadedly connected to the external threaded connector 601. The bottom end of the venturi tube 603 is inserted into the connecting hole 503. In the inner wall of 03, the Venturi tube 603 and the connecting seat 604 are coaxially arranged with the blow hole 4, and there is no air leakage at the weld. The coaxial arrangement of the Venturi tube 603, the connecting seat 604 and the blow hole 4 ensures that the airflow from the blow hole 4 can enter the Venturi tube 603 in a straight line, avoiding local airflow turbulence or airflow loss caused by airflow direction deviation. This allows the airflow to be more evenly distributed inside the Venturi tube 603 and then smoothly enter the filter bag body 501, improving the filtration efficiency of the filter bag body 501. At the same time, the coaxial design ensures the docking accuracy between the Venturi tube 603 and the blow hole 4, reduces the deviation during welding, and facilitates the welding and fixing of the connecting seat 604 with the blow hole 4 and the Venturi tube 603. The air-leakage design at the weld can prevent the dust-laden airflow from leaking from the weld gap.

[0027] Reference Figure 3 , Figure 4 and Figure 5A first silicone sealing gasket 602 is fixedly connected to the upper surface of the top cover 502. The first silicone sealing gasket 602 is sleeved on the outer surface of the external threaded connector 601. The first silicone sealing gasket 602, sleeved on the outside of the external threaded connector 601, can directly cover the gap between the external threaded connector 601 and the internal threaded sleeve 605, effectively preventing airflow leakage from these gaps. Due to the good elasticity and sealing properties of silicone, even during long-term use, the first silicone sealing gasket 602 can fill the gaps through its own deformation, preventing a decrease in dust removal efficiency due to air leakage. It also prevents unfiltered dust-laden airflow from entering the venturi tube 603 or the blow hole 4, reducing dust accumulation in subsequent pipelines and lowering dust levels. The equipment maintenance frequency is such that the upper surface of the first silicone sealing gasket 602 abuts against the bottom surface of the internal threaded sleeve 605. When the internal threaded sleeve 605 is screwed into place with the external threaded connector 601, the upper surface of the first silicone sealing gasket 602 and the bottom surface of the internal threaded sleeve 605 are tightly abutted, which can further enhance the sealing effect. In the abutting state, the first silicone sealing gasket 602 can be subjected to the pressure of the internal threaded sleeve 605, thereby more fully fitting the upper surface of the top cover 502 and the bottom surface of the internal threaded sleeve 605, further eliminating the small gaps between the two parts. This design can effectively maintain the stability inside the dust collector body 1, and at the same time reduce energy waste caused by air leakage, and improve the economic efficiency of equipment operation.

[0028] Reference Figure 3 , Figure 4 and Figure 5A limiting ring 606 is fixedly connected to the pipe section of the venturi tube 603. A second silicone sealing gasket 607 is fixedly connected to the bottom surface of the limiting ring 606. The limiting ring 606 is fixed to the pipe section of the venturi tube 603 and can limit the position of the dust collector bag assembly 5. When the dust collector bag assembly 5 is connected to the internal thread sleeve 605 through the external threaded connector 601, the upper surface of the top cover 502 will contact the second silicone sealing gasket 607. The limiting ring 606 can limit the screwing depth of the external threaded connector 601 and prevent the bag body 5 from being damaged due to excessive screwing. 01. Excessive stretching or insufficient sealing due to shallow screwing can cause problems. Meanwhile, the limiting ring 606 restricts the shaking of the dust collector bag assembly 5 during equipment operation, preventing the bag body 501 from rubbing against the inner wall of the dust collector body 1 due to airflow impact, reducing wear on the bag body 501, and extending its service life. The second silicone sealing gasket 607 is located on the bottom surface of the limiting ring 606, preventing hard contact between the limiting ring 606 and the top cover 502 during the limiting process, thus providing cushioning protection and preventing damage due to collision. Furthermore, it can further fill the gap between the limiting ring 606 and the top cover 502, enhancing the overall sealing performance. The bottom surface of the second silicone sealing gasket 607 abuts against the upper surface of the top cover 502. On the one hand, through the elastic deformation of the silicone material, it can completely fill the gap between the limiting ring 606 and the top cover 502, preventing dust-laden airflow from entering the area above the limiting ring 606 through this gap during equipment operation, thereby preventing dust from accumulating in the venturi tube 603 or its interior. The accumulation of dust on the surface of the threaded sleeve 605 reduces thread jamming or airflow channel blockage caused by dust buildup, ensuring smooth assembly and disassembly of the dust collector bag assembly 5 and stable dust collection airflow. Furthermore, the second silicone sealing gasket 607 in its contact state provides support to the top cover 502. Combined with the limiting effect of the limiting ring 606, this ensures the dust collector bag assembly 5 maintains a stable installation position during equipment operation, preventing tilting or displacement due to uneven stress on the bag body 501 and maintaining stable dust collection efficiency. Example 2: A baghouse installation structure for a dust collector in a feed production grinder, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes that an exhaust pipe module 2 be installed on the top of the dust collector body 1. The existing exhaust pipe module 2 on the top of the dust collector body 1 serves as the exhaust channel, eliminating the need for additional exhaust pipes. This fully utilizes the existing equipment structure, reduces modification costs, and requires no alteration to the exhaust pipe module 2, meeting the feed mill's need for minimal downtime and low-cost modifications. An inspection door 3 is installed on the front of the dust collector body 1, and a base frame 7 is fixedly connected to the bottom of the dust collector body 1. The inspection door 3 on the top provides a convenient passage for the disassembly and assembly of the dust collector bag assembly 5. The staff only needs to open the inspection door 3 to reach into the dust collector body 1 and complete the engagement or disengagement of the external threaded connector 601 and the internal threaded sleeve 605. Unlike existing technologies, there is no need to try to disassemble and assemble the bag from the blocked top passage. This greatly reduces the difficulty of bag replacement, shortens maintenance time, and reduces the production downtime caused by the replacement of the dust collector bag assembly 5. The base frame 7 on the bottom of the dust collector body 1 can provide stable support for the entire dust collector.

[0029] The implementation principle of this application embodiment is as follows: When the pulverizer generates a dust-laden airflow, the airflow enters the dust collector body 1 and flows to each dust collector bag assembly 5. At this time, the dust in the dust-laden airflow is intercepted and filtered by the bag body 501, while the filtered clean airflow passes through the bag body 501, enters the external threaded connector 601 through the connecting hole 503 on the top cover 502, and then enters the venturi tube 603 through the mating channel between the external threaded connector 601 and the internal threaded sleeve 605. Subsequently, it flows upward along the venturi tube 603 to the blow hole 4, and finally exits the dust collector from the exhaust pipe module 2 connected to the blow hole 4. During this process, the first silicone sealing gasket 602 sleeved on the external threaded connector 601 abuts against the bottom surface of the internal threaded sleeve 605, and the mating limit is limited. The second silicone sealing gasket 607 on the bottom surface of the positioning ring 606 abuts against the upper surface of the top cover 502, which can effectively prevent unfiltered dust-laden airflow from leaking out of the gaps, ensuring that all airflow passes through the filter bag body 501 for filtration. When a lot of dust accumulates on the surface of the filter bag body 501, the jet cleaning system will introduce compressed airflow into the jet hole 4. The airflow is accelerated by the venturi tube 603 and then sprayed in reverse to blow the filter bag body 501, causing the dust on the surface of the filter bag body 501 to fall to the bottom of the dust collector body 1, thus achieving dust removal. If the filter bag needs to be replaced, the operator only needs to open the inspection door 3 on the front of the dust collector body 1, reach inside and unscrew the threaded connection between the external threaded connector 601 and the internal threaded sleeve 605, and the dust collector bag assembly 5 can be taken out and replaced without any modification to the top structure.
