Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter cleaning technology, specifically to an automatic filter cleaning machine that integrates brushing, sweeping, blowing, and suction. Background Technology
[0002] With the continuous advancement of the national strategies of "carbon neutrality" and "carbon peaking," and the rapid development of new infrastructure such as 5G / 6G and artificial intelligence, the upgrading and iteration of wireless communication networks has entered a period of development. The density of equipment in communication base stations is increasing, as is the power consumption and heat generation. This has led to a surge in the configuration and energy consumption of base station air conditioning. According to statistics, air conditioning energy consumption accounts for about 50% of the total power consumption of a base station. The widespread application of fresh air systems with automatic cleaning filter units in base station equipment rooms has greatly reduced the frequency of air conditioning use and power consumption. The high efficiency and energy saving of the fresh air system in the equipment room are inseparable from its core components: the automatic and efficient cleaning fresh air filter unit and the multi-functional cleaning machine with automatic brushing, blowing, and suction. These components ensure the reliability of the ventilation volume and air exchange rate in the equipment room, laying the foundation for the durability and stability of the fresh air system.
[0003] Currently, when fresh air is introduced into the fresh air system in the base station equipment room, dust accumulates on the fresh air filter screen over time, resulting in increasing ventilation resistance. Since the base stations are scattered and no one maintains or replaces them regularly, the filter screen eventually becomes completely blocked, preventing the fresh air system from introducing outdoor fresh air. This leads to ineffective heat exchange indoors and ultimately causes the fresh air system to malfunction.
[0004] Therefore, this patent optimizes the design for automatic filter cleaning and proposes an integrated brush, sweep, blow, and suction machine for automatic filter cleaning. Utility Model Content
[0005] To solve the aforementioned technical problems, this utility model provides an integrated brush, sweep, blow, and suction machine for automatic filter cleaning.
[0006] This utility model is achieved using the following technical solution: an automatic filter cleaning brush, sweep, blow, and vacuum integrated machine, including a support frame, a primary filter, and a secondary filter. A bracket is installed on the inner wall of one side of the support frame, and a high negative pressure vacuum fan is fixedly installed on the bracket. A frame plate is bolted to the inner side wall of the support frame, and a cleaning mechanism is installed on the frame plate. The cleaning mechanism includes a mounting plate, a drive rotary motor, a differential pressure sensor, a primary rotating shaft, a connecting ring, a primary mesh brush, a secondary rotating shaft, a secondary sweeping and suction plate, a secondary mesh brush, and a secondary vacuum nozzle.
[0007] Preferably, the primary filter and the secondary filter are bolted to the inner wall of the frame on the front of the support frame, the primary filter is located in front of the frame plate, the secondary filter is located in front of the primary filter, the mounting plate is bolted to the back of the frame plate, and the drive rotary motor is mounted on the back of the mounting plate.
[0008] Preferably, the differential pressure sensor is installed on one side of the drive rotary motor, and the output end of the drive rotary motor extends through the front of the mounting plate and is connected to the primary shaft via a bearing.
[0009] Preferably, the connecting ring is installed on the outer periphery of the primary rotating shaft, and the primary mesh brush is installed on both sides of the connecting ring through connecting ear plates, with the bristles of the primary mesh brush close to the primary filter screen.
[0010] Preferably, the front end of the primary rotating shaft extends through the front of the primary filter screen and is connected to the secondary rotating shaft via a bearing. A secondary sweeping and suction plate is installed on the outer periphery of the secondary rotating shaft.
[0011] Preferably, a secondary mesh brush is installed at one end of the front of the secondary sweeping and suction plate, and a secondary vacuum nozzle is installed at the other end of the front of the secondary sweeping and suction plate. Both the secondary mesh brush and the secondary vacuum nozzle are close to the secondary filter.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The cleaning mechanism of this utility model consists of a mounting plate, a drive rotary motor, a differential pressure sensor, a primary rotating shaft, a connecting ring, a primary mesh brush, a secondary rotating shaft, a secondary sweeping and suction plate, a secondary mesh brush, and a secondary suction nozzle. The differential pressure sensor measures the pressure difference before and after the filter to reflect the change in filter resistance. As the filter gradually becomes clogged, the resistance increases, and the pressure difference before and after the filter also increases accordingly. When the pressure difference reaches a set threshold, the cleaning mechanism is automatically activated. At this time, the drive rotary motor starts, causing the primary and secondary bearings to rotate synchronously, which in turn causes the primary and secondary mesh brushes to rotate in contact with the primary and secondary filters respectively. By brushing away the floating dust and lint on the filter, the secondary suction nozzle simultaneously vacuums the filter while the brushes are circulating and sweeping it. At the same time, it blows away small particles, poplar and willow catkins on the primary filter during air intake, achieving an automatic cleaning function for the primary and secondary filters, effectively solving the problems of filter clogging and the need for regular manual maintenance.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] Please see Figure 1 - Figure 4 The automatic filter cleaning brush, sweep, blow and vacuum integrated machine of this embodiment includes a support frame 1, a primary filter 11 and a secondary filter 16. A bracket 2 is installed on the inner wall of one side of the support frame 1. A high negative pressure vacuum fan 3 is fixedly installed on the bracket 2. A frame plate 4 is installed on the inner wall of the support frame 1 by bolts. The primary filter 11 and the secondary filter 16 are installed at intervals on the inner wall of the front of the support frame 1 by bolts. The primary filter 11 is located in front of the frame plate 4, and the secondary filter 16 is located in front of the primary filter 11.
[0021] Furthermore, a cleaning mechanism is installed on the frame plate 4. The cleaning mechanism is composed of a mounting plate 5, a drive rotary motor 6, a differential pressure sensor 7, a primary rotating shaft 8, a connecting ring 9, a primary mesh brush 10, a secondary rotating shaft 12, a secondary sweeping and suction plate 13, a secondary mesh brush 14, and a secondary vacuum nozzle 15.
[0022] Specifically, the high negative pressure vacuum cleaner 13 is installed inside the upper part of the integrated machine support frame 1 via the bracket 2. The primary filter 11 and the secondary filter 16 are installed on the inner wall of the frame on the front of the integrated machine support frame 1. The frame plate 4 is installed inside the integrated machine support frame 1 to stably support the cleaning mechanism.
[0023] Furthermore, the primary mounting plate 5 is bolted to the back of the frame plate 4, the drive rotary motor 6 is mounted on the back of the mounting plate 5, the differential pressure sensor 7 is mounted on one side of the drive rotary motor 6, the output end of the drive rotary motor 6 extends through the front of the mounting plate 5 and is connected to the primary rotating shaft 8 through a bearing, the connecting ring 9 is mounted on the outer periphery of the primary rotating shaft 8, and the primary mesh brush 10 is mounted on both sides of the connecting ring 9 through connecting ear plates, with the bristles of the primary mesh brush 10 close to the primary filter screen 11.
[0024] Furthermore, the front end of the primary rotating shaft 8 extends through the front of the primary filter 11 and is connected to the secondary rotating shaft 12 via a bearing. A secondary sweeping and suction plate 13 is installed on the outer periphery of the secondary rotating shaft 12. A secondary mesh brush 14 is installed at one end of the front of the secondary sweeping and suction plate 13, and a secondary vacuum nozzle 15 is installed at the other end of the front of the secondary sweeping and suction plate 13. Both the secondary mesh brush 14 and the secondary vacuum nozzle 15 are close to the secondary filter 16.
[0025] Specifically, the primary rotating shaft 8 and the secondary rotating shaft 12 are connected to the output end of the drive rotary motor 6 via bearings. The primary mesh brush 10 is installed on the outer periphery of the primary rotating shaft 8 via a connecting ring 9. The secondary mesh brush 14 and the secondary suction nozzle 15 are installed on the outer periphery of the secondary rotating shaft 12 via a secondary sweeping and suction plate 13. When the primary filter screen 11 and the secondary filter screen 16 become clogged due to dust and other lint, the differential pressure sensor 7 measures the pressure difference across the filter screen to reflect the change in filter screen resistance. As the filter screen gradually becomes clogged, the resistance increases, and the pressure difference across the filter screen also increases accordingly. When the pressure difference reaches the set threshold, the cleaning mechanism is automatically activated.
[0026] At this time, the drive motor 6 starts and drives the primary bearing 8 and the secondary bearing 12 to rotate synchronously, which in turn drives the primary mesh brush 10 and the secondary mesh brush 14 to rotate and adhere to the primary filter screen 11 and the secondary filter screen 16 respectively. By brushing away the floating dust and lint on the filter screen, the secondary suction nozzle 15 simultaneously sucks up the dust while the filter screen is being circulated and brushed. At the same time, it blows away the small particles, poplar and willow catkins on the primary filter screen 11 when the air is introduced, achieving the automatic cleaning function of the primary filter screen 11 and the secondary filter screen 16, effectively solving the problems of filter screen clogging and manual periodic maintenance.
[0027] The self-cleaning mechanism designed in this application not only cleans the deposits on the primary filter but also removes fine dust from inside the filter, achieving automatic cleaning of both the primary and secondary filters. This greatly improves the heat exchange efficiency in the base station equipment room, extends the lifespan of the fresh air system, and ensures the energy-saving effect of the fresh air system.
