Description

Technical Field

[0001] The utility model relates to the technical field of air filter cartridge components, and in particular to a fixed pleat-leveling device in an air filter cartridge. Background Art

[0002] An air filter element is a filter, also called an air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. The engine needs to inhale a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. The fixed pleat device in the air filter cartridge is a device used to fix and maintain the shape of the pleats in the air filter cartridge. The pleats are a key part of the air filter cartridge, which increases the surface area of ​​the filter material and improves the filtration efficiency. The function of the fixed pleat device is to ensure that the pleats remain uniform and will not deform or fold, and to maintain the stability of the filter cartridge and the effective filtration effect when the air flows through the filter cartridge. It is usually made of metal or plastic and is fixed inside the filter cartridge to maintain the shape of the pleats.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a pleated device is fixed in an air filter cartridge, including a pleated filter material 11, a support ring 1 is fixedly installed on the top of the pleated filter material 11, and a support ring 2 is fixedly installed on the bottom of the pleated filter material 11. An adjustable fixing mechanism 3 is arranged on the support ring 1, the pleated filter material 11, and the support ring 2. The adjustable fixing mechanism 3 includes a connecting block 31, and the connecting block 31 is fixedly installed on the outer wall of the support ring 1 and the support ring 2. A vertical cylinder 32 is fixedly installed on the outer wall of the connecting block 31, and a vertical column 33 is slidably connected to the inner wall of the vertical cylinder 32. The sides of the vertical cylinder 32 and the vertical column 33 are both provided with through holes 34, and a pin 35 is movably inserted in the inner cavity of the through hole 34. The pin 35 A receiving block 36 is fixedly installed on the outer wall of 5, and a matching wave strip 37 is fixedly installed at the end of the receiving block 36. The pin 35 can be movably inserted and positioned in the inner cavity of the through hole 34. The pin 35 is connected with the matching wave strip 37 through the receiving block 36, and the function of targeted fixing of the pleated filter material 11 according to the air pressure can be realized. If the passing air pressure of the inner cavity of the pleated filter material 11 is relatively large, five matching wave strips 37 are installed. If the passing air pressure of the inner cavity of the pleated filter material 11 is relatively low, two matching wave strips 37 are installed. When the air pressure is high, the number of matching wave strips 37 is increased to increase the support area and ensure the safety of the pleated filter material 11. When the air pressure is low, the number of matching wave strips 37 is reduced to reduce the support area and ensure the filtration efficiency of the pleated filter material 11.

[0021] As an implementation method in this embodiment, Figure 2As shown, an air hole 371 is opened on the outer surface of the fitting wave strip 37, and the fitting wave strip 37 fits with the outer wall of the pleated filter material 11. The fitting wave strip 37 is an arc-shaped structure as a whole. The material of the fitting wave strip 37 is set to be a shape memory alloy. The fitting wave strip 37 is elastic and can be bent to facilitate its fitting on the outer wall of the pleated filter material 11. Through the design of the air hole 371, the contact area between the fitting wave strip 37 and the pleated filter material 11 can be reduced, thereby improving the filtration efficiency of the pleated filter material 11.

[0022] As an implementation method in this embodiment, Figure 1 - Figure 4 As shown, an expansion platform 321 is fixedly installed on the outer wall of the vertical cylinder 32, an elastic member 322 is fixedly installed on the bottom of the expansion platform 321, and the bottom of the elastic member 322 is fixedly connected to the top of the vertical column 33. A pull handle 323 is slidably connected to the inner wall of the expansion platform 321, and the bottom of the pull handle 323 is fixedly connected to the top of the vertical column 33. The top of the pull handle 323 extends to the top of the expansion platform 321. A limit block 324 is fixedly installed on the top of the vertical cylinder 32, and the bottom of the limit block 324 is movably connected to the top of the vertical column 33. The pull handle 323 is pulled upward to cause the vertical cylinder 32 to move upward. The column 33 is subjected to a vertical upward force, which releases the initial elastic force of the elastic member 322 pressing down on the vertical column 33, and the pin 35 can be pulled out from the inside of the through hole 34, or the pin 35 can be inserted back into the inside of the through hole 34, and the pull handle 323 is released. The elastic force of the elastic member 322 applies a downward force to the vertical column 33, and the friction between the vertical column 33 and the pin 35 is used to complete the positioning of the pin 35, which is convenient for the operator to use. The limit block 324 is used to limit the pulled vertical column 33 so that the through hole 34 is aligned, which is convenient for the pin 35 to be inserted.

[0023] Working principle: Pull the handle 323 upward to release the initial elastic force of the elastic member 322 pressing down on the vertical column 33, and then the pin 35 can be pulled out from the inside of the through hole 34, or the pin 35 can be inserted back into the inside of the through hole 34, and then the handle 323 is released, and the elastic force of the elastic member 322 applies a downward force to the vertical column 33 to complete the positioning of the pin 35 and the matching wave strips 37. According to this design, the number of matching wave strips 37 can be increased when the air pressure is high, and the number of matching wave strips 37 can be reduced when the pressure is low, thereby realizing the function of targeted fixation of the pleated filter material 11 according to the air pressure.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
