Technical Field

[0001] This application relates to the field of air filters, and more particularly, to a polyurethane filter element air filter with high mechanical strength. Background Art

[0002] Filters are classified into: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, and air-conditioning filters according to different filtration functions.

[0003] The structure of the product can refer to an air filter element and an air filter disclosed in Chinese Patent Document No. 202321371951.0, which relates to the field of filters. It includes a top cover, a bottom cover, and a filter assembly disposed between the top cover and the bottom cover. The top cover is integrally connected to the filter assembly, and an external thread is provided on the outer side of the top cover; the filter assembly includes a nylon support layer, a filter screen layer, and a stainless steel woven mesh layer. The filter screen layer is coated on the outer side of the nylon support layer, and the stainless steel woven mesh layer is coated on the outer side of the filter screen layer. The air filter of this application can quickly disassemble and assemble the filter element. The filter element can be washed with water, with good washing effect, high washing efficiency, and can be reused after washing; the filter element can be regularly replaced through quick disassembly and assembly, and the operation is simple and convenient.

[0004] However, only one filter element is used for filtering dust in this patent, resulting in poor filtering effect. At the same time, the filter element in this patent is fixed, so that dust may block the filter element and affect the effect.

[0005] Now, a polyurethane filter element air filter with high mechanical strength is provided. Summary of the Invention

[0006] This part of the content of this application is used to briefly introduce the concepts, which will be described in detail in the following Detailed Description part. This part of the content of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the above background art section, some embodiments of the present application provide a polyurethane filter element air filter with high mechanical strength, including: a box body with an open top; a first filter net detachably installed on the top of the box body; fixing bolts threadedly connected to the first filter net and threadedly connected to the box body; a second filter net arranged inside the box body and below the first filter net; a moving brush movably arranged on the second filter net; a moving component arranged on the box body for moving the moving brush back and forth; a mounting plate fixedly connected inside the box body and below the second filter net; a dust suction fan fixedly connected to the mounting plate; a filter cartridge arranged below the dust collector, with an open top, and the filter cartridge is detachably installed inside the box body; a connecting plate fixedly connected inside the box body and arranged on the top of the filter cartridge, and the air outlet pipe of the dust suction fan is communicated with the connecting plate; an air outlet opened on the box body; a cleaning component arranged inside the box body for cleaning the filter cartridge.

[0008] When dust suction is required, first, the dust suction fan can be started, so that dust enters the box body through the top of the box body. Then, under the action of the first filter net, larger dust is initially isolated. Then the dust enters the box body, and under the action of the second filter net, larger dust is isolated again. At the same time, the double-shaft motor can be started, so that the output shaft of the double-shaft motor drives the driving bevel gear to rotate, thereby driving the driven bevel gear to rotate, so that the lead screw rotates back and forth, and the moving brush moves back and forth. Under the action of the cleaning brush, the second filter net is cleaned, thus preventing dust from blocking the second filter net and affecting the air intake effect of the second filter net. And the fixing bolts can be rotated to open the fixing bolts. Then part of the dust and air enter the filter cartridge through the air outlet pipe of the dust suction fan. Under the action of the filter cartridge, filtration is carried out again. At the same time, when the double-shaft motor is started, under the action of the two discs and the belt, the cleaning rod rotates, thereby cleaning the inner wall of the filter cartridge. And under the action of the first gear and the second gear, the output shaft of the double-shaft motor can drive the filter cartridge to rotate, so that the cleaning rod and the cleaning strip clean the inner wall of the filter cartridge, further preventing dust from blocking the filter cartridge. And when there is more dust in the filter cartridge, the mounting bolts can be rotated to remove the bottom plate of the box body. Then the mounting seat clamping component and the filter cartridge can be removed to clean the dust in the filter cartridge. At the same time, the screw can be rotated to move the clamping plate, so as to clamp or not clamp the filter cartridge, which is convenient for removing and installing the filter cartridge and improves the dust suction effect.
