Description

An air filter back-blowing self-cleaning device

Technical Field

The invention relates to the technical field of air filtration, in particular to an air filtration back-blowing self-cleaning device.

Background technique

An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Air is generally used as the compression medium because it is compressible, clear and transparent, easy to transport (non-condensing), harmless, safe, and inexhaustible.

Air filters for air compressors generally use wood pulp fiber or synthetic fiber filter elements. During use, dust and impurities gradually accumulate, resulting in increased pressure loss and decreased energy efficiency. Depending on the operating conditions, the replacement cycle ranges from 1000h to 4000h, which wastes resources and increases the user's use and maintenance costs.

Regularly cleaning the dust accumulated on the surface of the filter element can effectively reduce the pressure loss of the filter element and extend the service life of the filter element. For the air compressor industry, a large-flow pre-filter is usually added to the front of the unit. The fiber filter element also needs to be replaced regularly. The self-cleaning air filter can extend the service life of the pre-filter by regularly cleaning the outer surface of the filter element. However, the pre-filter still requires special manual regular maintenance. The location of some air filters is also difficult for staff to enter, which also increases the system cost. There is an urgent need for an air filter back-blowing self-cleaning device for air compressors that can effectively solve the dust accumulation problem of air filter elements.

Detailed ways

As shown in Figures 1-8, the present invention provides a technical solution: an air filter back-blowing self-cleaning device, including a mounting shell 1, a back-blowing mechanism 4 is arranged on the top of the mounting shell 1, and the back-blowing mechanism 4 includes: an output pipe 41, the top of the mounting shell 1 is fixed to the bottom of the output pipe 41, the inner wall of the output pipe 41 is fixed to the surface of the fixing ring 42, the inner wall of the output pipe 41 is fixed to the surface of the fixing block 43, the top of the fixing block 43 is hinged to the bottom of the trapezoidal plate 44, the inner wall of the output pipe 41 is fixed to one end of the connecting rod 45, the other end of the connecting rod 45 is fixed to the surface of the connecting sleeve 46, and the connecting sleeve 46 is fixed to the inner wall of the output pipe 41. The inner wall of the sleeve 46 is fixed to one end of the spiral spring 47, the other end of the spiral spring 47 is fixed to the surface of the connecting shaft 48, and the bottom of the connecting shaft 48 is fixed to the fan 49. When the air compressor stops working, the air is no longer blown upward, and the spiral spring 47 is released to drive the fan 49 to rotate through the connecting shaft 48. The fan 49 drives the air to flow downward, and the trapezoidal plates 44 return to their original positions under the action of gravity, so that the gap between the trapezoidal plates 44 is reduced, making the downward-flowing air more rapid, which is convenient for blowing the impurity particles on the surface of the air filter 24 downward, thereby playing a role in the self-cleaning of the air filter 24.

An air filter installation mechanism 2 is provided on the inner wall of the installation shell 1, and the air filter installation mechanism 2 includes a mounting groove 22. The inner wall of the installation shell 1 is provided with a mounting groove 22, and the inner wall of the mounting groove 22 is plugged into the surface of the air filter housing 21. An inclined surface 23 is provided at the bottom of the inner wall of the installation shell 1. The inner wall of the air filter housing 21 is fixed to the air filter 24. The air filter 24 is inserted into the mounting groove 22 so that the side with the air filter 24 enters the mounting groove 22, which is convenient for installing and removing the air filter 24.

A collecting mechanism 3 is provided on the top of the mounting shell 1. The collecting mechanism 3 includes an input pipe 31. The bottom of the mounting shell 1 is fixed to the top of the input pipe 31. The inner wall of the input pipe 31 is hinged to the left side of the baffle 32. The inner wall of the input pipe 31 is fixed to one end of a torsion spring 33. The other end of the torsion spring 33 is fixed to the bottom surface of the baffle 32. The inner wall of the input pipe 31 is fixed to the top of the fixing plate 34. The left inner wall of the input pipe 31 is fixed to one end of a spring 35. The other end of the spring 35 is fixed to the top of a limit block 36. The left inner wall of the input pipe 31 is plugged into the right side of the collecting frame 37. When the upward air stops, the torsion spring 33 drives the baffle 32 to return to its original position. When the baffle 32 returns to its original position, it will knock on the inner wall of the input pipe 31, and the knocking force is transmitted to the mounting shell 1. The knocking force makes it easier to remove the foreign particles on the surface of the air filter 24. When the baffle 32 returns to its original position, the foreign particles enter the collection frame 37 along the top surface of the baffle 32. Since the collection frame 37 is made of transparent material, when the collection frame 37 is found to be full, the collection frame 37 can be pulled to the left by hand. The top baffle 32 of the collection frame 37 contacts the limit block 36, so that the limit block 36 squeezes the spring 35 upward, releasing the limit of the collection frame 37 by the limit block 36. When the dumping is completed, the collection frame 37 is pressed into the inner wall of the input frame, which facilitates collection and cleaning.

The output pipe 41 is a hollow cylindrical tube, the middle part of the fixing ring 42 is a circular ring, and the two sides of the fixing ring 42 are short rods. The fixing ring 42 is located at the top of the trapezoidal plate 44, and the fixing block 43 is a cylinder with a hexagonal prism groove. The number of trapezoidal plates 44 is six, and the two trapezoidal plates 44 are arranged in a circular array. The number of connecting rods 45 is two, and the two connecting rods 45 are arranged symmetrically. The connecting sleeve 46 is a cylinder with a cylindrical groove, and the connecting shaft 48 is a long rod. The connecting shaft 48 passes through the bottom of the connecting sleeve 46, and the connecting shaft 48 is slidably connected to the connecting sleeve 46. The air passes through the air filter 24 upward, and the impurity particles in the air are filtered. The air continues to blow the trapezoidal plate 44 upward to rotate with the hinge point as the center of the circle until the trapezoidal plate 44 conflicts with the fixing ring 42. The gap between the trapezoidal plates 44 increases, which is convenient for air to pass through. The air causes the fan 49 to rotate, and the fan 49 drives the volute spring 47 to store force.

One end of the air filter housing 21 is plugged into the inner wall of the mounting groove 22 , and the other end of the air filter housing 21 extends out of the surface of the mounting housing 1 , and the inclined surface 23 is a prism-shaped groove.

The input pipe 31 is a hollow rectangular parallelepiped, and a through groove is provided on the left surface of the input pipe 31. When the air compressor is turned on, air flows upward from the input pipe 31 through the mounting shell 1 and then enters the output pipe 41. The air blows the baffle 32, causing the baffle 32 to rotate around the hinge point until the left surface of the baffle 32 contacts the bottom of the fixed plate 34, and the air passes upward through the right side of the baffle 32.

The right side of the baffle 32 is in contact with the inner wall of the input tube 31, the surface of the limit block 36 is slidably connected to the left inner wall of the input tube 31, the bottom of the limit block 36 is semi-cylindrical, a horizontal plate is fixed on the top of the collection frame 37, the top horizontal plate of the collection frame 37 is in contact with the limit block 36, and the collection frame 37 is made of transparent material.

When in use, the air filter 24 is inserted into the installation groove 22 so that one side of the air filter 24 enters the installation groove 22 , which facilitates installation and removal of the air filter 24 .

When the air compressor is turned on, air flows upward from the input pipe 31 through the mounting shell 1 and then into the output pipe 41 . The air blows the baffle 32 , causing the baffle 32 to rotate around the hinge point until the left surface of the baffle 32 contacts the bottom of the fixing plate 34 , and the air passes upward through the right side of the baffle 32 .

The air continues to pass through the air filter 24 upward, and the impurity particles in the air are filtered. The air continues to blow the trapezoidal plate 44 upward to rotate with the hinge point as the center until the trapezoidal plate 44 contacts the fixing ring 42. The gap between the trapezoidal plates 44 increases to facilitate the passage of air. The air causes the fan 49 to rotate, and the fan 49 drives the volute spring 47 to store force.

When the air compressor stops working, the air is no longer blown upward, and the volute spring 47 is released to drive the fan 49 to rotate through the connecting shaft 48. The fan 49 drives the air to flow downward, and the trapezoidal plates 44 return to their original positions under the action of gravity, so that the gap between the trapezoidal plates 44 is reduced, making the downward-flowing air more rapid, making it easier to blow the impurity particles on the surface of the air filter 24 downward, thereby achieving the self-cleaning effect of the air filter 24.

When the upward air stops, the torsion spring 33 drives the baffle 32 to return to its original position, and the baffle 32 will knock on the inner wall of the input pipe 31 when returning to its original position. The knocking force is transmitted to the mounting shell 1, and the knocking force makes it easier to remove the foreign particles on the surface of the air filter 24.

When the baffle 32 returns to its original position, the foreign particles flow into the collection frame 37 along the top surface of the baffle 32. Since the collection frame 37 is made of transparent material, when the collection frame 37 is found to be full, the collection frame 37 can be pulled to the left by hand, and the top baffle 32 of the collection frame 37 contacts the limit block 36, so that the limit block 36 squeezes the spring 35 upward, releasing the limit of the collection frame 37 by the limit block 36. When the pouring is completed, the collection frame 37 is pressed into the inner wall of the input frame, which facilitates collection and cleaning.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
