Description

TECHNICAL FIELD

[0001] The application relates to a dust filtering device for a bag cutting machine for improving air pollution. BACKGROUND

[0002] In the field of industrial dust filtration, a filtering device using a circular filter plate matched with a sleeve is widely used in dust control scenes such as chemical industry and machining due to its compact structure and convenient installation. The device usually fixes the filter plate at the bottom end of the sleeve, and realizes gas-solid separation through negative pressure formed by the upper end suction pump, so as to discharge the treated gas meeting environmental protection requirements. However, a series of technical problems to be solved are derived based on this.

[0003] In actual operation, the center area of the filter plate is prone to bulging deformation under the action of suction negative pressure and dust particle impact, which will cause the fixed area of the filter plate edge and the sleeve to be warped due to the center bulging, and will cause the edge sealing structure to fail. No matter whether a flange is pressed tightly, a buckle is connected or a glue is sealed, the filter plate warping will damage the edge adhesion, causing the dust-containing airflow to leak from the fixed area. This not only causes the dust to bypass the filter plate and enter the suction system, causing abnormal wear of downstream equipment such as suction pump impeller and pipeline, but also causes the dust emission concentration to exceed the standard, violating environmental protection requirements.

[0004] In addition, the bulging deformation of the filter plate will also significantly affect the uniformity of the dust distribution on its surface. The surface curvature of the deformed filter plate changes, the airflow velocity in the center area increases to form a "high-speed scouring area", and the edge area becomes a "dust retention area" due to the reduced flow rate. The high-speed area dust particle penetration rate increases, resulting in a decrease in filtration accuracy, and the retention area is locally blocked due to dust accumulation, aggravating the pressure difference between the two sides of the filter plate. This uneven load distribution will cause the filter plate material to bear periodic alternating stress, especially in the transition area between the bulging area and the fixed edge, which is prone to stress concentration, causing the filter plate to appear fatigue cracks or damage prematurely. In the dust suction environment, this problem is particularly prominent, and the filter plate often needs to be replaced frequently, which seriously affects the production continuity.

[0005] In addition, the adhesion of the deformed filter plate and the sleeve is poor, causing the disassembly to be stuck during maintenance. The bulging edge of the filter plate will mechanically interfere with the inner wall of the sleeve, especially when a precision-fitted metal sleeve is used. The jamming phenomenon will increase the disassembly time, and even cause the filter plate to tear due to forced disassembly. At the same time, the curved structure of the bulging part greatly increases the difficulty of dust cleaning, and the traditional back-blowing or mechanical vibration cleaning method cannot effectively remove the residual dust in the recessed part. Manual cleaning not only consumes a lot of manpower, but also damages the surface of the filter plate due to improper operation, forming a vicious cycle.

[0006] Therefore, the application provides a dust filtering device for a bag cutting machine to improve air pollution to solve the above problems. SUMMARY

[0019] Compared with the prior art, the present application provides a dust filtering device for a bag cutting machine for improving air pollution, which has the following

[0020] Advantages:

[0021] 1. The convenient and detachable dust filtering mechanism can replace the filter plate in the dust filtering device as a whole, which can bring the following benefits to the overall work:

[0022] Solve the problem of stuck disassembly: the mechanism adopts a whole replacement method, which can avoid mechanical interference between the protruding filter plate edge and the inner wall of the sleeve, greatly reduce the disassembly time, avoid the risk of filter plate tearing caused by sticking, improve the maintenance efficiency, and reduce the maintenance cost.

[0023] Improve the convenience of maintenance: the traditional dust cleaning method cannot clean the residual dust in the concave part of the protruding part, but the whole replacement can directly take out the filter plate with residual dust, without the need for complex cleaning operation in the device, reducing the workload and difficulty of manual cleaning, avoiding the problem of damage to the surface of the filter plate caused by improper manual cleaning operation, thereby breaking the vicious cycle of maintenance, making the maintenance work more convenient and efficient.

[0024] 2. Through the design of the pressure equalizing support leak prevention mechanism, the following advantages are achieved in maintaining dust uniformity and providing reverse support:

[0025] Maintain dust uniformity, improve filtration efficiency and quality: the design of the flexible scraper can maintain the uniformity of the dust on the flat filter plate, allowing each part of the filter plate to fully play its filtering role, avoiding filtration failure caused by local dust accumulation or penetration, thereby improving the cleanliness of the filtered gas, achieving higher filtration precision and quality standards, and better meeting environmental protection and production requirements.

[0026] Prolong the service life of the filter plate: uniform distribution of dust can balance the stress on each area of the filter plate, prevent local areas from accelerating material aging and damage due to excessive pressure and wear, reduce stress concentration, slow down material fatigue, thereby prolonging the service life of the filter plate, reducing the replacement frequency, and saving maintenance costs.

[0027] Lower operating energy consumption: uniform dust distribution can maintain low and stable airflow resistance, avoid airflow resistance increase caused by local blockage, so that the suction pump does not need to consume excessive energy to maintain operation, thereby reducing energy consumption, saving energy cost, and improving the economy of system operation.

[0028] Provide reverse support and enhance the stability of the filter plate: the reverse support of the impact wind flow on the filter plate in the plane state by the telescopic rod can effectively resist the force caused by the suction negative pressure and the impact of dust particles, reduce the deformation of the filter plate, especially prevent the center area from bulging due to stress, maintain the plane state of the filter plate, and enhance its stability during operation;

[0029] Protect the edge sealing structure: since the filter plate is not easy to deform, the edge and the fixed area of the sleeve can maintain good fit, avoiding the destruction of the edge sealing structure caused by warping deformation due to center bulging;

[0030] Reduce the maintenance workload: the stable filter plate structure can reduce the failure rate caused by deformation, reduce the additional maintenance operation due to serious local dust accumulation or sealing failure, and also facilitate the use of standardized and efficient dust cleaning method, making the cleaning work more convenient and thorough, reducing the working intensity and maintenance frequency of the maintenance personnel, and improving the maintenance efficiency.

[0031] 3、The cooperation of the dust uniform adjustment assembly and the anti-deformation support assembly in the application can optimize the performance of the filter system from multiple dimensions, and the following are the specific beneficial effects brought by them:

[0032] Significantly improve the stability of the filter system and reduce airflow impact unevenness: the cooperation of the two can effectively reduce the airflow impact unevenness caused by uneven dust distribution, make the external force on the filter plate more balanced, avoid abnormal vibration or shaking caused by excessive local stress, thereby improving the stability of the entire filter system during operation, reducing the noise and the risk of loose parts caused by vibration of the equipment;

[0033] Reduce the deformation of the filter plate: by optimizing the uniformity of dust distribution and weakening the influence of airflow impact unevenness, the possibility of deformation of the filter plate is greatly reduced, the problem of center bulging caused by deformation is prevented, and the structural integrity of the filter plate is maintained, providing reliable protection for stable operation of the system;

[0034] Efficiently suppress dust-containing airflow leakage and protect the edge seal: deformation of the filter plate is an important reason for the loose edge seal and dust-containing airflow leakage; the cooperation of the two components suppresses the deformation of the filter plate, thereby protecting the sealing structure of the filter plate edge and the fixed area of the sleeve, preventing the destruction of the edge fit caused by warping deformation, effectively preventing dust-containing airflow from leaking from the fixed area, avoiding dust bypassing the filter plate into the suction system, and reducing the abnormal wear of downstream equipment such as the impeller of the suction pump and the pipeline.

[0035] Relieve material fatigue: uniform dust distribution and balanced airflow impact force make the stress on the filter plate material more uniform, avoid stress concentration phenomenon, reduce the periodic alternating stress on the filter plate material, effectively relieve material fatigue, delay the appearance of fatigue cracks or damage, thereby prolong the service life of the filter plate;

[0036] Improve the perfection and practicality of the mechanism function, and optimize the performance: the dust uniform adjustment assembly and the anti-deformation support assembly cooperate with each other to solve the problem from two key angles of dust distribution and structural support, forming a whole that is complementary in function and synergistic in effect. Compared with the effect of a single component, it can more comprehensively and effectively solve various problems faced by the filter plate, significantly improve the performance of the pressure equalizing and supporting leakage prevention mechanism. The perfect pressure equalizing and supporting leakage prevention mechanism can better adapt to the dust filtration needs under different working conditions.

[0075] The strip hole 7204 can be used for the suction air flow to pass through.

[0076] The dust uniformity adjusting assembly 71 can cooperate with the anti-deformation support assembly 72 to reduce the unevenness of the air flow impact force on the filter plate 610 caused by the uneven distribution of the dust on the premise of improving the uniformity, and reduce the dust-containing air flow leakage caused by the deformation of the filter plate 610.

[0077] The working principles of all the contents in the above embodiments are as follows:

[0078] The working process of the convenient disassembly dust filtering mechanism 6 is as follows:

[0079] In use, first, the head pipe 602, the threaded part 603, and the tail pipe 611 are assembled. The specific operation steps are that the threaded part 603 at the upper end and the lower end of the rotating body 608 is respectively screwed to the head pipe 602 and the tail pipe 611. In this process, the rotating body 608 moves in the adaptive cavity 604 opened in the threaded part 603, which provides stable assistance for the movement. When the assembly is completed, the external suction pump connected to the main pipe 601 can be used to perform dust suction treatment on the main pipe 601 and the auxiliary pipe composed of the head pipe 602, the rotating body 608, and the tail pipe 611 during the cutting process. That is, when the material to be cut 2 on the cutting frame 1 is conveyed by the transmission wheel 4 on the auxiliary frame 3 and cut by the cutting knife 5, the dust generated during the cutting is suctioned and transferred by the auxiliary pipe composed of the head pipe 602, the rotating body 608, and the tail pipe 611.

[0080] Further, the convenient disassembly dust filtering mechanism 6 adopts the head pipe 602, the rotating body 608, and the tail pipe 611 splicing mode, which can effectively replace the filter plate in the dust filtering device as a whole, effectively solving the disassembly jamming problem. That is, for the disassembly jamming problem caused by the poor fit of the deformed filter plate and the sleeve, the mechanism adopts the whole convenient replacement mode, which can avoid mechanical interference between the edge of the convex filter plate 610 and the inner wall of the sleeve, greatly reduce the disassembly time, avoid the tearing risk of the filter plate 610 caused by jamming, improve the maintenance efficiency, and reduce the maintenance cost.

[0081] Improve maintenance convenience: The traditional dust cleaning method is difficult to clean the residual dust in the convex part, and the whole replacement can directly take out the filter plate 610 with residual dust without complex cleaning operation in the equipment, reducing the workload and difficulty of manual cleaning, avoiding the problem of damaging the surface of the filter plate 610 due to improper manual cleaning operation, thereby breaking the vicious cycle of maintenance, making the maintenance work more convenient and efficient.

[0082] The above working process is described in detail in the following Figures 1 to 8 .

[0083] The working process of the dust uniform adjustment assembly 71 and the anti-deformation support assembly 72 in the pressure equalization support leakage prevention mechanism 7 is as follows:

[0084] Further, in the dust suction process, the screw rod 7102 on the outward expansion plate 7101 drives the rotating body 608 to rotate with the filter plate 610 fixedly installed therein through the screw groove 609 opened on the rotating body 608. In this process, the annular guide ring 605, the buckling ring 606 and the spring 607 in the adaptive cavity 604 provide assistance for the rotation. In the rotation, due to the centrifugal force, the dust impacting on the filter plate 610 is uniformly distributed to a certain extent thereon. Further, in addition thereto, the flexible scraper 7104 on the flow guide ring 7103 also uniformly distributes the dust on the filter plate 610 to avoid uneven distribution of the dust on the filter plate 610 under the action of the suction airflow.

[0085] Further, in the uniform distribution process of the flexible scraper 7104 on the bottom surface of the filter plate 610, the connecting rod 7202 fixedly connected in the head tube 602 through the four-corner piece 7201 brings the telescopic rod 7203 at the bottom end to limit the flatness of the top surface of the filter plate 610, that is, the filter plate 610 is in a symmetrical clamping and limiting state of the flexible scraper 7104 and the telescopic rod 7203.

[0086] Further, through the design of the uniform pressure support and leakage prevention mechanism 7, the dust uniformity can be effectively maintained, the filtration efficiency and quality can be improved in terms of maintaining the dust uniformity and providing reverse support. Specifically, through the design of the flexible scraper 7104, the dust uniformity on the planar filter plate 610 can be maintained, and each part of the filter plate 610 can fully play a filtering role, avoiding filtering failure caused by local dust accumulation or penetration, thereby improving the cleanliness of the filtered gas, achieving higher filtration precision and quality standards, and better meeting environmental protection and production requirements.

[0087] In addition, uniform dust distribution can balance the stress of each region of the filter plate 610, prevent local areas from bearing excessive pressure and wear to accelerate material aging and damage, reduce stress concentration, slow down material fatigue, thereby prolonging the service life of the filter plate 610, reducing the replacement frequency, and saving maintenance costs.

[0088] Further, uniform dust distribution can maintain relatively low and stable airflow resistance, avoid increasing airflow resistance due to local blockage, and enable the suction pump to operate without consuming excessive energy, thereby reducing energy consumption, saving energy costs, and improving the economy of system operation.

[0089] At the same time, the reverse support of the impact airflow on the planar filter plate 610 by the telescopic rod 7203 can effectively resist the force caused by the suction negative pressure and dust particle impact, reduce the deformation of the filter plate 610, especially prevent the central region from protruding due to stress, maintain the planar state of the filter plate 610, and enhance the stability thereof in the working process.

[0090] Further, the cooperation of the dust uniform adjustment assembly 71 and the anti-deformation support assembly 72 can optimize the performance of the filtering system from multiple dimensions, significantly improve the stability of the filtering system, and reduce airflow impact unevenness. That is, the cooperation of the two can effectively reduce the airflow impact unevenness caused by uneven dust distribution, make the external force received by the filter plate 610 more balanced, avoid abnormal vibration or shaking caused by excessive local stress, thereby improving the stability of the entire filtering system during operation, reducing the noise and the risk of loosening of parts caused by vibration of the equipment;

[0091] In addition, the deformation of the filter plate 610 can be reduced, the possibility of deformation of the filter plate 610 is greatly reduced by optimizing the uniformity of dust distribution and weakening the influence of airflow impact unevenness, the problem of central bulging caused by deformation is prevented, the structural integrity of the filter plate 610 is maintained, and reliable protection is provided for stable operation of the system;

[0092] Moreover, the design can efficiently suppress dust-containing airflow leakage and protect the edge seal. Since the deformation of the filter plate 610 is an important reason for the loose edge seal and dust-containing airflow leakage, the cooperation of the two assemblies suppresses the deformation of the filter plate 610, thereby protecting the sealing structure of the edge of the filter plate 610 and the fixed area of the sleeve, preventing the destruction of the edge fit caused by warping deformation, effectively preventing dust-containing airflow from leaking from the fixed area, avoiding dust bypassing the filter plate 610 into the suction system, and reducing the abnormal wear of downstream equipment such as the impeller of the suction pump and the pipeline;

[0093] Further, material fatigue can be alleviated. Uniform dust distribution and balanced airflow impact make the stress on the material of the filter plate 610 more uniform, avoiding stress concentration and reducing the periodic alternating stress on the material of the filter plate 610, effectively alleviating material fatigue, delaying the occurrence of fatigue cracks or damage, and thereby prolonging the service life of the filter plate 610;

[0094] The lifting mechanism has perfect functionality and practicality, and the performance is optimized in cooperation. The dust uniform adjustment assembly 71 and the anti-deformation support assembly 72 cooperate with each other to solve problems from two key angles of dust distribution and structural support, forming a whole that is complementary in function and synergistic in effect. Compared with the function of a single component, the dust uniform adjustment assembly 71 and the anti-deformation support assembly 72 can more comprehensively and effectively solve various problems faced by the filter plate 610, significantly improve the performance of the pressure-equalizing support and leakage-suppressing mechanism 7, and the perfect pressure-equalizing support and leakage-suppressing mechanism 7 can better adapt to dust filtering needs under different working conditions. Whether it is a high-concentration dust environment or a working scene with complex airflow conditions, the mechanism can stably function, improving the adaptability and universality of the mechanism in actual application.
