Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to an air filter housing. Background Art

[0002] In the air handling system, large-flow air filters play a vital role. They are responsible for removing impurities such as particles, dust, pollen, etc. in the air to ensure that the air quality meets specific standards.

[0003] The existing Chinese utility model patent with application number 202222559380.5 discloses a large-flow air filter, which intercepts and filters large particles in the air and protects the precision filter by setting a conical coarse filter layer in the pipeline. The above scheme has the following problems. First, due to the large air flow, dust and impurities can be accumulated quickly on the surface of the coarse filter, which not only reduces the filtration efficiency, but also may hinder air circulation and affect the overall performance of the system. Secondly, the process of cleaning the filter usually relies on manual operation, and professionals are required to regularly disassemble, clean or replace the filter. The addition of a coarse filter not only increases the maintenance cost, but also increases the labor intensity. Utility Model Content

[0004] The utility model provides an air filter housing, which solves the problem of time-consuming and labor-intensive maintenance and cleaning of the filter screen in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] An air filter housing comprises a pipeline, wherein a one-way plate, a filter device and a fan are sequentially arranged from the air inlet end to the air outlet end of the pipeline, the pipeline between the one-way plate and the filter device is connected with an ash discharge pipeline, and an ash discharge valve is arranged on the ash discharge pipeline, the one-way plate comprises a plurality of limit rods staggered and fixed in the pipeline, a plurality of baffles are hinged on the side of the limit rod close to the filter device, the top end of the baffle is hinged to the horizontal limit rod in a one-to-one correspondence, when the pipeline stops passing air, the baffles will overlap in sequence and close the pipeline, and the airflow generated by the fan is now directed toward the filter device.

[0008] Furthermore, the toggle device is placed between the filter device and the fan. The support rod is not only used to transmit vibration to clean the filter plate, but also provides additional support for the filter plate, helping the filter plate to withstand the wind force generated by the fan when running, reducing the risk of deformation or damage of the filter plate caused by excessive wind force.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , 2 As shown in Figures 6 and 7, the embodiment of the utility model provides an air filter housing, including a pipeline 1, a one-way plate 2, a filter device 3 and a fan 4 are sequentially arranged from the air inlet end to the air outlet end of the pipeline 1, the pipeline 1 between the one-way plate 2 and the filter device 3 is connected with an ash discharge pipeline 5, and an ash discharge valve is arranged on the ash discharge pipeline 5, the one-way plate 2 includes a plurality of limit rods 7 staggered and fixed in the pipeline 1, and a plurality of baffles 8 are hinged on the side of the limit rod 7 close to the filter device 3, and the top of the baffle 8 is hinged with the horizontal limit rod 7 one by one, when the pipeline 1 stops passing air, the baffles 8 will overlap in sequence and close the pipeline 1, and the airflow generated by the fan 4 is directed toward the filter device 3. The fan 4 is a prior art.

[0026] In the process of filtering air, the air will blow the one-way plate 2, causing the baffle 8 on the one-way plate 2 to rotate, and the end of the baffle 8 will be away from the limit rod 7. Then the air passes through the filter device 3, and the dust in the air is blocked on the side of the filter device 3 close to the one-way plate 2. When the filter device 3 needs to be cleaned, the air intake of the pipeline 1 is closed, and then the baffle 8 is automatically closed under the action of gravity, and then the dust discharge valve is opened, and the fan 4 is started at the same time. The fan 4 provides airflow to the filter device 3, and the airflow blows off the dust remaining on the filter device 3 and drives the dust to be discharged from the dust discharge pipeline 5. The airflow generated by the fan 4 reversely sweeps the filter device 3, which can efficiently remove the dust accumulated on the filter device 3, avoiding the cumbersome problems of traditional manual cleaning. The dust discharge is facilitated by the dust discharge pipeline 5 and the dust discharge valve, reducing the difficulty and time cost of maintenance. The characteristic of the baffle 8 automatically closing under the action of gravity enables the equipment to naturally form a sealed state when it stops working, preventing dust and other pollutants from entering the pipeline 1 again.

[0027] like Figure 3-5 As shown, the filtering device 3 includes a frame 9 clamped in the pipeline 1, a serrated filter plate 10 is arranged in the frame 9, a toggle device is arranged on one side of the filter plate 10, and the toggle device includes a driving motor 11, the driving motor 11 is connected to a driving rod 12, the driving rod 12 is connected to a rack 14 through a half gear 13, both ends of the rack 14 are sleeved with support tubes 15, the support tubes 15 are respectively fixed on both sides of the pipeline 1, one of the support tubes 15 is provided with a spring 16, the spring 16 is against the end of the rack 14, and the side wall of the rack 14 is connected to a plurality of support rods 17, the support rods 17 are respectively placed in the tooth grooves of the filter plate 10, and correspond to the tooth grooves one by one.

[0028] During the cleaning process of the filter device 3, the drive motor 11 is started, and the drive motor 11 moves the rack 14 along the support tube 15 through the rotation of the half gear 13. The rack 14 compresses the spring 16 during the movement, and the rack 14 drives the multiple support rods 17 to move. The shaking of the support rods 17 is controlled to drive the filter plate 10 to vibrate, making it easier for particles attached to the filter plate 10 to fall off. Through effective cleaning, the blockage of the filter plate 10 is reduced, and its air permeability is maintained, thereby reducing equipment wear and failure caused by the accumulation of dust on the filter plate 10, and extending the service life of the entire filter device 3.

[0029] like Figure 2 As shown, the toggle device is placed between the filter device 3 and the fan 4. By placing the toggle device between the filter device 3 and the fan 4, the toggle device can reduce the shielding of the filter plate 10, so that the air can pass through the filter plate 10 more smoothly, thereby improving the utilization rate of the filter plate 10, and the support rod 17 of the toggle device can provide support for the filter plate 10, enhancing the structural stability of the filter plate 10, so that it can withstand greater wind force without being easily deformed or damaged, reducing the replacement frequency and maintenance cost.

[0030] like Figure 1 , 2 As shown in Figures 6 and 7, a filter through hole 18 is provided on the pipe 1, and a lifting rail 19 is fixed on the pipe 1 at the filter through hole 18. Two filter sleeves 20 slide on the lifting rail 19. The filter device 3 and the toggle device are both arranged in the filter sleeve 20, and the lifting rail 19 is sealed and slidably connected with the filter sleeve 20. The lifting rail 19 is a prior art. When the filter device 3 needs to be replaced, the filter sleeve 20 is controlled to move along the lifting rail 19, so that the filter sleeve 20 can quickly switch different filter devices 3 as needed, which is convenient for the disassembly and replacement of the filter device 3 and adapting to different filtering requirements or dealing with emergencies. And because the replacement process is simpler, the operator can check and replace the filter device 3 more frequently, so as to ensure that the equipment is always in the best working state, thereby improving the reliability and stability of the equipment. Since the filter device 3 can be replaced and upgraded relatively independently, the equipment can be easily modified and upgraded according to technological progress or application requirements.

[0031] like Figure 1 , 2 As shown in FIG. 6 , the end of the dust discharge pipe 5 is connected to a disposable filter bag 21. When the filter bag 21 is full of dust, the dust dropped from the filter plate 10 can be easily collected by the disposable filter bag 21. After the dust collection is completed, a new filter bag 21 can be directly replaced, which reduces the need for frequent cleaning or replacement of the traditional filter device 3, reduces maintenance costs, and improves work efficiency.

[0032] The filter through hole 18 is sealed and connected to the filter sleeve 20 via a sealing ring. The sealing ring is a prior art. As an intermediate piece connecting the filter through hole 18 and the filter sleeve 20, the sealing ring can effectively fill the small gap between the two, thereby improving the sealing performance of the filter through hole 18 and the filter sleeve 20, preventing air leakage, and ensuring the efficient operation of the filtration system.

[0033] like Figure 1 , 2 As shown, the filter through hole 18 is clamped with the filter sleeve 20 through an electromagnetic clamp 22. The electromagnetic clamp 22 is a prior art. The filter sleeve 20 is fixed by the electromagnetic clamp 22, which effectively prevents the filter sleeve 20 from accidentally falling off during operation, thereby avoiding damage to the filter device 3 or safety accidents caused by the filter sleeve 20 falling off, ensuring the stable operation of the equipment and the safety of personnel.

[0034] like Figure 2 As shown, a small wind turbine 6 is provided between the one-way plate 2 and the filter device 3. The small wind turbine 6 is a prior art. The small wind turbine 6 can generate electric energy by using the wind flowing in the pipeline 1, realizes energy recovery and reuse, reduces the dependence on external power supply, and the wind turbine consumes part of the kinetic energy of the air during rotation, thereby reducing the flow rate of the air passing through the filter device 3, which helps to make the air pass through the filter device 3 more evenly, improves the filtering efficiency, and at the same time, the reduced wind speed also gives the filter device 3 more time to capture and filter the particles in the air, further improving the filtering quality.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
