Description

Technical Field

[0001] This utility model relates to the field of air filter technology, and in particular to a backwashing air filter silencer. Background Technology

[0002] An air filter silencer is a device that can filter dust and impurities from the air and reduce aerodynamic noise. Its filtration principle usually utilizes structures such as centrifugal force, oil film, and filter screen to separate, adsorb, or intercept dust particles in the airflow, thereby purifying the air. The silencer principle includes using tangential air intake to increase air damping and segmentation, using porous sound-absorbing materials to absorb sound energy, reflecting sound waves through abrupt changes in the acoustic characteristics of the pipe, and setting a silencer cap and causing the air to expand multiple times to reduce noise propagation. It is commonly used in aerodynamic equipment such as air compressors and fans.

[0003] Currently, most mainstream air filter silencers on the market achieve noise reduction by simply increasing the thickness of the device or using reflectors. However, such structures have limited noise reduction effects due to relying solely on physical reflection, making it difficult to meet the demand for high-efficiency noise reduction. Furthermore, backwash filters are prone to dust leakage during long-term use or due to impact damage. Existing devices generally lack effective dust cleaning mechanisms, and internal dust accumulation further weakens the noise reduction performance, ultimately significantly reducing the practicality and service life of the device. Therefore, there is an urgent need to design a backwash air filter silencer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a backwashing air filter silencer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A backwash air filter silencer includes a main body, a housing is provided on one side of the main body, and a silencer assembly and a switching assembly are respectively provided inside the housing;

[0007] The noise reduction assembly includes a noise reduction base, a socket is inserted into the noise reduction base, a movement groove is formed inside the socket, a guide noise reduction plate is provided on the inner wall of the movement groove, a flow groove is formed on the inner wall of the movement groove near the guide noise reduction plate, a noise reduction groove is provided on the inner wall of the flow groove, and a flushing hole is formed on the inner wall of the noise reduction groove.

[0008] Preferably, the noise reduction component further includes a flow guide groove, which is connected to the motion groove.

[0009] Preferably, the top outer wall of the silencing base is provided with connecting pipes on both sides, and the connecting pipes are connected to the motion groove.

[0010] Preferably, the switching assembly includes a connecting pipe and a screw, the outer wall of the screw is threaded with a threaded sleeve, and the connecting pipe is slidably connected with a sealing plate.

[0011] Preferably, a sliding rod is bolted to the outer wall of the threaded sleeve, and the sliding rod is slidably connected to the sealing plate.

[0012] Preferably, a connecting rod is bolted to the outer wall of one end of the threaded sleeve, and a connecting plate is bolted to one end of the connecting rod.

[0013] Preferably, a connecting ring is bolted to one side of the outer wall of the connecting plate, and both the connecting ring and the connecting pipe have slots inside.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. With the sound-absorbing components in place, when noise enters the motion slot, it can be efficiently reduced by the synergistic effect of the guide sound-absorbing plate, the flow slot and the sound-absorbing slot. At the same time, the flushing hole equipped with the device supports regular flushing and maintenance, which can effectively remove internal dust and significantly improve the sound-absorbing performance, thereby greatly enhancing the practicality and long-term stability of the device.

[0016] 2. Through the innovative design of the switching component, when the rotating drive screw is driven, the screw can synchronously drive the slide bar and the connecting ring through the precision transmission of the threaded sleeve, ensuring that the airflow channel remains unobstructed during the backflushing air injection process. This design not only significantly improves the practical performance and backflushing effect of the device, but also effectively solves the problem of reduced filtration efficiency caused by obstructed backflushing airflow in traditional devices.

[0028] The following are several preferred embodiments or application embodiments to help those skilled in the art better understand the technical content of this utility model and the technical contributions made by this utility model compared with the prior art:

[0029] Example 1

[0030] A backwash air filter silencer includes a main body 1, a housing 4 is provided on one side of the main body 1, and a silencer assembly 2 and a switching assembly 3 are respectively provided inside the housing 4;

[0031] The noise reduction assembly 2 includes a noise reduction base 21, with a socket 22 inserted inside the noise reduction base 21. The socket 22 has a movement groove 29 inside, and a guide noise reduction plate 23 is provided on the inner wall of the movement groove 29. A flow groove 25 is provided on the inner wall of the movement groove 29 near the guide noise reduction plate 23, and a noise reduction groove 24 is provided on the inner wall of the flow groove 25. A flushing hole 26 is provided on the inner wall of the noise reduction groove 24. When air enters the interior of the movement groove 29, the air can first contact the guide noise reduction plate 23, which will reduce the noise. The air then enters the interior of the noise reduction groove 24 through the flow groove 25. At this time, other noise will also enter the interior of the noise reduction groove 24, causing the noise to come into contact with each other and thus achieve the purpose of noise reduction. Furthermore, the noise reduction is effectively improved by using the other movement groove 29 and connecting pipe 28.

[0032] The silencing component 2 includes a flow guide 27, which is connected to the movement groove 29. The flow guide 27 allows air to circulate more effectively. Connecting pipes 28 are provided on both sides of the top outer wall of the silencing base 21, and are connected to the movement groove 29. When air enters the connecting pipe 28, the connection with the movement groove 29 enhances airflow. The switching component 3 includes a connecting pipe 31 and a screw 32. A threaded sleeve 33 is threaded onto the outer wall of the screw 32. A sealing plate 34 is slidably connected inside the connecting pipe 31. When the screw 32 is rotated, the threaded connection between the screw 32 and the threaded sleeve 33 allows the threaded sleeve 33 to move. A sliding rod 35 is bolted to the outer wall of the threaded sleeve 33, and the sliding rod 35 slides against the sealing plate 34. The threaded sleeve 33 is dynamically connected. When the threaded sleeve 33 moves, it can drive the sliding rod 35 to move, allowing the sliding rod 35 to slide within the connecting pipe 31 through a sliding connection with the sealing plate 34. A connecting rod 36 is bolted to one end of the outer wall of the threaded sleeve 33, and a connecting plate 37 is bolted to one end of the connecting rod 36. When the threaded sleeve 33 moves, it can drive the connecting rod 36 to move, and the connecting rod 36 can drive the connecting plate 37 to move. A connecting ring 38 is bolted to one side of the outer wall of the connecting plate 37. Both the connecting ring 38 and the connecting pipe 31 have slots 39 inside. When the connecting plate 37 moves, it can drive the connecting ring 38 to move, and the connecting ring 38 can drive the slots 39 to move, allowing air to enter the interior of the connecting pipe 28.

[0033] Working principle: During use, when backflushing, simply inject air into the connecting pipe 31. This allows the device to backflush the main body 1 through the connection between the connecting pipe 31 and the main body 1. Then, by rotating the screw 32, the screw 32 can move through the threaded connection with the threaded sleeve 33. As the threaded sleeve 33 moves, it drives the sliding rod 35 to move. The sliding rod 35 can slide through the sealing plate 34, allowing the sealing plate 34 to slide inside the connecting pipe 31 and be fully inserted into the interior of the connecting pipe 31. At this time, the connecting rod 36 and the connecting plate 34... 7 and the connecting ring 38 can move, causing the slot 39 to move, allowing air to enter the interior of the silencer seat 21 through the slot 39. When the air enters the interior of the moving slot 29, it first contacts the guide silencer plate 23, which will silence the noise. Then, it enters the interior of the silencer slot 24 through the flow slot 25. At this time, other noise will also enter the interior of the silencer slot 24, causing the noise to come into contact with each other and thus achieve the purpose of silencing. Then, it enters another silencing step through the guide slot 27. Finally, through another connecting pipe 28, the air passes through the other side of the connecting pipe 31 and is finally discharged.
