Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air filter structure with adjustable air intake and exhaust volume. Background Technology

[0002] Because industrial production generates a large amount of dust, workers who work in dusty environments for extended periods are susceptible to pneumoconiosis. Pneumoconiosis poses a significant threat to people's health and is difficult to cure. For the sake of workers' health, factories should install dust collectors to treat the dust. Filter cartridges are an important component of dust collectors. Filter cartridges, also known as air filter elements or air purifiers, are cylindrical filtration devices primarily used to intercept and remove particulate matter, dust, and other impurities from the air.

[0003] China Patent Network (patent publication number CN214345179U) discloses an air filtration cartridge, including a metal mesh support, a pleated filter material, a cover plate, and a base. A motor is detachably installed inside the base. The pleated filter material is detachably fixed to the metal mesh support. The metal mesh support has a bottom plate and an opening at the top. The rotating shaft of the motor is fixedly connected to the bottom plate for rotation. An extendable outer cover is fixed on the base. When the outer cover rises to completely cover the outside of the pleated filter material, the cover plate closes on the outer cover.

[0004] The aforementioned air filter cartridge, during use, uses a rotating metal mesh support to shake off dust from the filter media surface, facilitating cleaning and long-term use. However, this filter cartridge lacks adjustable inlet and outlet airflow during filtration, making it unable to quickly dilute pollutant concentrations in heavily polluted environments. Furthermore, it cannot reduce the load on the filter cartridge by decreasing the inlet and outlet airflow in everyday low-pollution environments, resulting in a short service life and a fixed, non-adjustable overall structure. Therefore, we propose an air filter cartridge structure with adjustable inlet and outlet airflow. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide an air filter structure with adjustable air intake and exhaust volume to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable air filter cartridge structure, comprising an outer frame, an adjustable filter mechanism fixed at one end of the outer frame, the adjustable filter mechanism comprising a device frame, a circuit control board fixed inside the device frame, a thermal wind speed sensor electrically connected to one side of the circuit control board, a servo motor fixed in the middle of the circuit control board, a rotating shaft connected to one end of the servo motor, an inner filter cartridge fixed to one end of the rotating shaft, an inner filter screen groove formed on the outer wall of the inner filter cartridge, a filter media cartridge fitted around the inner wall of the inner filter cartridge, a sealing plate engaged at one end of the device frame, connecting rods distributed around the sealing plate, an outer cover fixed to one end of the connecting rod, a handle bracket connected to the outer wall of the outer cover, and a rubber frame surrounding the four edges of the outer cover.

[0008] Furthermore, the thermal wind speed sensor and the servo motor are electrically connected to the circuit control board via wires, and one end of the inner filter cartridge forms a rotating structure with the servo motor via a rotating shaft.

[0009] Furthermore, the inner filter screen grooves are distributed in a ring around the inner filter cylinder and are continuous, and the inner filter cylinder is attached to the inner wall around the outer frame.

[0010] Furthermore, the filter media cartridge is evenly attached to the inner wall of the inner filter cartridge, and the filter media cartridge is made of activated carbon material.

[0011] Furthermore, the outer cover is fixedly connected to one side of the equipment frame via a connecting rod, and the rubber frame is evenly fitted along the four perimeter edges of the outer cover.

[0012] Furthermore, the outer frame includes an outer filter cylinder, and the outer wall of the outer filter cylinder is surrounded by and has an outer filter screen groove. One end of the outer filter cylinder is fixedly connected to a device frame, and a high-pressure nozzle is provided at the center of the other end of the outer filter cylinder. One end of the high-pressure nozzle is connected to a solenoid valve.

[0013] Furthermore, the center of the outer filter cartridge is aligned with the high-pressure nozzle, and the high-pressure nozzle is connected to the solenoid valve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The filter cartridge structure is controlled by a rotating shaft and servo motor connected to one end of the inner filter cartridge. The airflow within the air purification equipment can be monitored by a thermal wind speed sensor. Based on different wind speeds, the servo motor can be controlled to adjust the rotation of the inner filter cartridge. This allows the inner filter screen groove on the outer wall of the inner filter cartridge to form an alternating fit with the outer filter screen groove of the fitted outer filter cartridge. This, in turn, adjusts the size of the gap between the inner and outer filter screen grooves, thereby controlling the inlet and outlet airflow. This avoids continuous load in low-pollution environments and saves filter material resources.

[0016] When cleaning and maintaining the filter cartridge structure, the filter media cartridge that is locked inside the inner wall of the inner filter cartridge can be slid out directly during use and cleaning. At the same time, both the inner and outer filter screen grooves are equipped with mesh-like filter screens, which makes it easier to filter dust.

[0017] The filter cartridge in this air purification device mainly consists of an outer filter cartridge and an inner filter cartridge. The outer filter cartridge uses a circumferential mesh groove to filter and intercept dust in the gas. In conjunction with a high-pressure nozzle at one end of the outer filter cartridge, high-pressure gas can be injected into the interior of the outer filter cartridge during maintenance and cleaning by using the high-pressure nozzle connected to the air purification device itself to remove surface dust and facilitate subsequent processing.

[0026] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figure 1-4 An adjustable air filter cartridge structure is shown, including an outer frame 1. An adjustable filter mechanism 2 is fixed to one end of the outer frame 1. The outer frame 1 includes an outer filter cartridge 101. An outer filter screen groove 102 is arranged around the outer wall of the outer filter cartridge 101 and passes through it. An equipment frame 201 is fixedly connected to one end of the outer filter cartridge 101. A high-pressure nozzle 103 is arranged at the center of the other end of the outer filter cartridge 101. A solenoid valve 104 is connected to one end of the high-pressure nozzle 103.

[0029] To ensure the proper functioning of the entire filter cartridge within the air purification equipment, such as Figure 1-2 As shown, the filter cartridge in this air purification device mainly consists of an outer filter cartridge 101 and an inner filter cartridge 206. The outer filter cartridge 101 is surrounded by an outer filter screen groove 102, which provides filtration and interception of gas dust. In conjunction with the high-pressure nozzle 103 at one end of the outer filter cartridge 101, high-pressure gas is injected into the outer filter cartridge 101 through the high-pressure nozzle 103 connected to the air purification device itself during maintenance and cleaning, so that the surface dust can be discharged, which is convenient for subsequent treatment.

[0030] like Figure 2-4 As shown, the adjustable filter mechanism 2 includes a device frame 201. A circuit control board 202 is fixed inside the device frame 201. A thermal wind speed sensor 203 is electrically connected to one side of the inside of the circuit control board 202. A servo motor 204 is fixed in the middle of the inside of the circuit control board 202. A rotating shaft 205 is connected to one end of the servo motor 204. An inner filter cylinder 206 is fixed to one end of the rotating shaft 205. An inner filter screen groove 207 is opened on the outer wall of the inner filter cylinder 206. A filter material cylinder 208 is attached to the inner wall of the inner filter cylinder 206. A sealing plate 209 is engaged at one end of the device frame 201. Connecting rods 210 are distributed around the sealing plate 209. An outer cover 211 is fixed to one end of the connecting rod 210. A handle bracket 212 is connected to the outer wall of the outer cover 211. A rubber frame 213 is arranged around the four edges of the outer cover 211.

[0031] To provide adjustable filtration capacity for different environmental requirements, such as Figure 2-4As shown, this filter cartridge structure is controlled by a rotating shaft 205 and a servo motor 204 connected to one end of the inner filter cartridge 206. The airflow inside the air purification device can be monitored by a thermal wind speed sensor 203. Based on different wind speeds, the servo motor 204 can be controlled to adjust the rotation of the inner filter cartridge 206. This allows the inner filter screen groove 207 on the outer wall of the inner filter cartridge 206 to be staggered with the outer filter screen groove 102 of the outer filter cartridge 101, thereby adjusting the size of the gap between the inner filter screen groove 207 and the outer filter screen groove 102. This controls the airflow, thereby avoiding continuous load in low-pollution environments and saving filter material resources.

[0032] When cleaning and maintaining the above-mentioned filter cartridge structure, the filter media cartridge 208 that is engaged with the inner wall of the inner filter cartridge 206 can be slid out directly during use and cleaning. At the same time, the inner filter screen groove 207 and the outer filter screen groove 102 are both provided with mesh-like filter screens, which makes it easier to filter dust.

[0033] In summary, when this filter cartridge structure is in use, firstly, when the filter cartridge structure is inside the air purification equipment cavity for filtration, when air is blown into the air purification equipment by the fan, the airflow force of the blown air can be monitored by the thermal anemometer 203. When the external air purification equipment's fan force is adjusted to be large, the thermal anemometer 203 can transmit the real-time monitoring data to the circuit control board 202, and the controller in the circuit control board 202 controls the servo motor 204. The servo motor 204 drives the connected rotating shaft 205 and the inner filter cartridge 206 to rotate synchronously. At this time, the inner filter screen grooves 207 arranged around the inner filter cartridge 206 move along the outer filter cartridge 1. 01. The inner wall is rotated to fit the filter cartridge. At this time, the staggered openings of the inner filter screen groove 207 and the outer filter screen groove 102 are expanded and adjusted, so that the inlet and outlet of the filter cartridge are in line with the air volume of the purification equipment, thus making it more suitable for filtration. After filtration is completed, high-pressure air can be introduced through the high-pressure nozzle 103 connected to the air purification equipment. Then, after the solenoid valve 104 is opened, the high-pressure nozzle 103 is opened to inflate the inner filter cartridge 206, thereby blowing off the dust on the surface of the outer filter cartridge 101. Then, by holding the handle 212, the outer cover 211 and the entire filter cartridge are pulled out simultaneously, and the filter material cartridge 208 on the inner wall of the inner filter cartridge 206 can be removed, thus completing the cleaning.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
