Description

Technical Field

[0001] This utility model belongs to the technical field of blower room technology, and specifically relates to a filter device for the air inlet of a blower room. Background Technology

[0002] A blower room is a functional building space primarily used to house blower equipment. It is established to meet the needs of industrial production, municipal facilities, and other fields for blower systems. In terms of internal structure, it is laid out around the blower, with a solid floor and suitable space to support and install these devices. It is also equipped with corresponding pipe connection ports to facilitate the delivery of the airflow generated by the blower to the target usage location. Its building construction also takes into account the special requirements of the equipment during operation, such as ventilation and heat dissipation, sound insulation and noise reduction, thereby ensuring that the blower can work normally in a relatively stable and safe environment.

[0003] Chinese Patent No. CN207299329U discloses an air inlet filter device for a blower room. The device comprises a metal sound-insulating plate on the inner wall of its housing, with several grooves on the inner side of the plate. An air inlet cavity is located at the top of the housing, with metal filter screens on both sides. Baffles are arranged obliquely on the inner side of the filter screens. Air outlet cavities are located on both sides of the housing, with small fans inside and louvers on the outer surface. A shock-absorbing layer is located at the bottom of the housing, with several blowers above it and partitions between adjacent blowers. A temperature sensor is located at the top of the housing. This invention allows for the circulation of hot air within the blower room, accelerating air convection and achieving rapid cooling and heat dissipation. It also provides sound insulation and noise reduction.

[0004] While the aforementioned device demonstrated convenience to some extent during actual use, it still has some shortcomings. Specifically, the structure of the air inlet is relatively simple, employing only a filter to assist in dust filtration. Over long-term use, dust easily accumulates on the filter, and this accumulation significantly impacts the ventilation efficiency inside the blower room. Due to obstructed ventilation, the heat dissipation efficiency inside the blower room is also greatly reduced. Clearly, this situation affects the overall performance of the device, resulting in certain defects and deficiencies during its use. Therefore, to better utilize the device and improve its efficiency and performance, improvements are urgently needed. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a blower room air inlet filter device to solve the problem of lack of dustproof and cleaning structure during the application of the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A blower room air inlet filtration device includes a blower room body, a ventilation window is provided at the upper front end of the blower room body, mounting rails are fixedly installed on both sides of the ventilation window, a filter mechanism is slidably connected inside the mounting rails, the rear end of the filter mechanism extends and covers the interior of the ventilation window, an adjustment mechanism is fixedly installed at the lower front end of the blower room body, and a drive mechanism is fixedly installed at the top of the adjustment mechanism.

[0008] The filtration mechanism includes a movable plate that is slidably connected to the inside of a mounting rail.

A cleaning component is movably installed inside the conical filter screen.

[0009] As a preferred technical solution, the cleaning component includes a fixing member, which is fixedly installed on the front of the annular disk in a ring-shaped arrangement with equal spacing. A slip ring is rotatably connected to the inner side of the fixing member, and a brush plate is fixedly installed on the inner side of the slip ring with equal spacing. The outer side of the brush plate is in close contact with the inner wall of the conical filter screen.

[0010] As a preferred technical solution, the adjustment mechanism includes a slide rail, which is fixedly installed on the lower front of the blower room body. A slide plate is slidably connected inside the slide rail. The drive mechanism is fixedly installed on the front of the slide plate. A hand-tightening screw is threadedly connected to the lower end of the slide plate, and the end of the hand-tightening screw passes through the slide plate.

[0011] As a preferred technical solution, the slide rail has limit holes arranged linearly at equal intervals inside, and the end of the hand-tightening screw is inserted into the limit holes.

[0012] As a preferred technical solution, the drive mechanism includes a side arm and a gear ring. The side arm is fixedly installed on the front of the slide plate, and a drive motor is fixedly installed on the upper end of the side arm.

Wear-resistant pads are fixedly connected to the outer surfaces of the sliding plate and the movable plate.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device uses a drive mechanism and a filter mechanism in conjunction. The drive motor is started to drive the gear to rotate, which in turn drives the gear ring to rotate and then drives the slip ring and brush plate to rotate inside the conical filter screen. The conical filter screen is conical, which increases the filtration and ventilation area and improves the filtration efficiency. Its inclined surface can quickly remove dust and improve the dust cleaning efficiency. The whole device can maintain the ventilation efficiency and heat dissipation effect inside the blower room for a long time, and maximize the service life of the blower. The rotation of the brush plate effectively brushes and cleans the inside of the conical filter screen, ensuring good ventilation.

[0017] Secondly, the adjustment mechanism facilitates the disassembly and assembly of the conical filter screen during use. When disassembly or assembly is required, loosen the hand-tightening screw to move it forward and disengage it from the limiting hole.

During installation, insert the filter mechanism into the ventilation window, adjust the movable plate to move upward, and insert the limiting rod into the positioning hole to limit the slide plate. At the same time, the gear and the gear ring mesh, and the drive motor can drive the brush plate to clean. The entire filter mechanism is easy to disassemble and assemble quickly, making the device convenient to use. Attached Figure Description

A filter mechanism 6 is slidably connected inside the mounting rails 4. The rear end of the filter mechanism 6 extends and covers the interior of the ventilation window 2. An adjustment mechanism 3 is fixedly installed at the lower front end of the blower room body 1. A drive mechanism 5 is fixedly installed on the top of the adjustment mechanism 3.

[0025] The filter mechanism 6 includes a movable plate 61, which is slidably connected to the interior of the mounting rail 4. An annular disc 62 is fixedly installed on the inner side of the movable plate 61, and a conical filter screen 63 is fixedly installed on the back of the annular disc 62. The conical filter screen 63 is inserted into the interior of the ventilation window 2 and covers the outer side of the ventilation window 2. A cleaning component 64 is movably installed inside the conical filter screen 63. The ventilation window 2 at the upper front end cooperates with the filter mechanism 6, which is slidably connected to the mounting rail 4 on the back. The movable plate 61 of the filter mechanism 6 slides within the mounting rail 4, ensuring easy installation and removal. For ease of use, the annular disc 62 on the inner side of the movable plate 61 and the conical filter 63 on the back can effectively cover the ventilation window 2 and filter the air entering the blower room 1. The conical filter 63 has a unique shape, which increases the filtration and ventilation area and improves filtration efficiency. On the other hand, its sloping surface can quickly remove dust and improve dust cleaning efficiency. The rear end of the filter mechanism 6 extends and covers the inside of the ventilation window 2 to ensure comprehensive filtration. The internal cleaning component 64 can clean the conical filter 63 to maintain the filter's good filtration performance and extend its service life.

[0026] refer to Figures 1-3 The cleaning component 64 includes a fixing member 641, which is fixedly installed on the front of the annular disk 62 in a ring-shaped arrangement with equal spacing. A slip ring 642 is rotatably connected to the inner side of the fixing member 641. A brush plate 643 is fixedly installed on the inner side of the slip ring 642 with equal spacing. The outer side of the brush plate 643 is in close contact with the inner wall of the conical filter screen 63.

[0027] refer to Figures 3-4The adjusting mechanism 3 includes a slide rail 31, which is fixedly installed on the lower front of the blower chamber 1. A slide plate 32 is slidably connected inside the slide rail 31. The drive mechanism 5 is fixedly installed on the front of the slide plate 32. A hand-tightening screw 33 is threadedly connected to the lower end of the slide plate 32, and the end of the hand-tightening screw 33 passes through the slide plate 32. Limiting holes 34 are linearly arranged at equal intervals inside the slide rail 31, and the end of the hand-tightening screw 33 is inserted into the limiting holes 34. Fixing members 641 are arranged in a ring at equal intervals and fixed on the front of the annular disc 62, providing stable support for the slip ring 642. The slip ring 642 can... The inner side of the fixing component 641 rotates, driving the brush plates 643, which are fixed at equal intervals on the inner side, to move. The outer side of the brush plates 643 is in close contact with the inner wall of the conical filter screen 63. When the slip ring 642 rotates, the brush plates 643 can effectively brush and clean the inner wall of the conical filter screen 63. This design can remove dust and other impurities attached to the conical filter screen 63 in a timely manner, preventing dust accumulation from affecting ventilation efficiency. At the same time, through continuous cleaning, the good filtration performance of the conical filter screen 63 can be maintained, extending the service life of the filter screen and ensuring that the blower room always maintains a good ventilation state, creating favorable conditions for the normal operation of the blower.

[0028] refer to Figures 1-2 The drive mechanism 5 includes a side arm 51 and a gear ring 52. The side arm 51 is fixedly installed on the front of the slide plate 32. A drive motor 53 is fixedly installed on the upper end of the side arm 51. A gear 54 is fixedly installed through the output end of the drive motor 53. The gear ring 52 is fixedly installed on the front of the slip ring 642. The gear 54 and the gear ring 52 are meshed together. Positioning holes 55 are provided at the bottom of both the mounting rail 4 and the movable plate 61. Limiting rods 56 are fixedly installed on the upper ends of both sides of the slide plate 32. The ends of the limiting rods 56 are inserted into the positioning holes 55. The internal cross-sectional shape of the slide rail 31 and the mounting rail 4 is convex. The overall cross-sectional shape of the movable plate 61 and the slide plate 32 is also convex. Wear-resistant pads are fixedly connected to the outer surface. The gear 54 at the output end of the drive motor 53 mounted on the side arm 51 meshes with the gear ring 52 on the front of the slip ring 642, providing power for the operation of the cleaning component 64. This enables the brush plate 643 to efficiently clean the inner wall of the conical filter screen 63, ensuring the stability of each component during operation and improving the overall reliability of the device. The convex cross-section design of the slide rail 31, mounting rail 4, movable plate 61, and sliding plate 32 makes them more stable when sliding and less prone to misalignment. At the same time, the wear-resistant pads on the outer surface of the sliding plate 32 and movable plate 61 can reduce friction loss, extend the service life of the device, and ensure the long-term stable operation of the filtration and cleaning system in the blower room.

[0029] Operating principle and advantages: By setting the drive mechanism 5 and the filter mechanism 6 to cooperate with each other, the device can drive the gear 54 to rotate by starting the drive motor 53 during actual use. When the gear 54 rotates, it can drive the gear ring 52 to rotate. The rotation of the gear ring 52 can assist in driving the slip ring 642, which in turn drives the brush plate 643 to rotate inside the conical filter screen 63. Through the rotation of the brush plate 643, the inside of the conical filter screen 63 can be effectively brushed and cleaned. The conical filter screen 63 is conical, and this unique design can greatly increase its filtration and ventilation area, thereby significantly improving the filtration efficiency. At the same time, the inclined surface of the conical filter screen 63 has a good guiding effect, which can quickly export the cleaned dust, further improving the dust cleaning efficiency of the device. Overall, this design can maintain the ventilation efficiency inside the blower room 1 for a long time, thereby improving its overall ventilation and heat dissipation effect and maximizing the service life of the blower inside the blower room 1.

[0030] By setting the adjustment mechanism 3, when it is necessary to disassemble or assemble the conical filter screen 63 during use, the hand-tightening screw 33 can be loosened to move it forward. When the hand-tightening screw 33 disengages from the limiting hole 34, the sliding plate 34 can be adjusted to slide downwards. As the sliding plate 34 moves downwards, the limiting rod 56 disengages from the positioning hole 55. With the limiting rod 56 separating from the positioning hole 55, the movable plate 61 and the mounting rail 4 are no longer restricted, and the movable plate 61 can be pulled out from inside the mounting rail 4, thereby realizing the disassembly and assembly of the entire ventilation window's internal filter mechanism 6. When installation is required, simply reinsert the filter mechanism 6 into the internal slot of the ventilation window 2. At this time, by adjusting the slide plate 34 upward, on the one hand, the limiting rod 56 is inserted into the positioning hole 55, which can limit the movable plate 61 in the mounting rail 4; on the other hand, it can also drive the gear 54 and the gear ring 52 at the output end of the drive motor 53 to mesh and connect. At this time, the drive motor 53 can drive the gear 54 to drive the gear ring 52, causing the brush plate 643 to perform brushing and cleaning. It can be seen that the filter mechanism 6 is easy to disassemble and assemble quickly, which greatly facilitates the use of the device.
