Description

Technical Field

[0001] The utility model relates to the technical field of flow - equalizing plate air filters, and particularly relates to a flow - equalizing plate air filter. Background Art

[0002] Air purification filters are widely used. The uniformity of the wind speed after filtration is an important index for installing air purification filtration equipment. The filter is made by folding a filter paper with the same density into a wavy shape, and the resistance of its filter material is basically the same. When using the filter, usually an air inlet and a wind hood are installed on the upper part of the filter. The area of the air inlet is smaller than that of the filter, and the air outlet in the middle of the air inlet is large while the air outlet near the pipe wall around is small, resulting in a large local pressure. At the place with large pressure, the filtered air volume is large and the wind speed is fast, while at the place with small pressure, the filtered air volume is small and the wind speed is slow. Eventually, the wind speed at the bottom of the filter is uneven, and the use efficiency of the filter is low. Content of the Utility Model

The pressing plate is correspondingly pressed and limited with a plurality of the limiting components.

[0005] Further, the outer frame is provided with two groups of first frame bodies and two groups of second frame bodies.

The two groups of first frame bodies are both slidably matched with the fixed frame. A plurality of the limiting components are correspondingly arranged at the bottoms of the two groups of second frame bodies. Both ends of the first frame body are provided with guide grooves and positioning holes. The positioning holes are correspondingly arranged in the middle of the guide grooves. Both ends of the second frame body are provided with guide plates and mounting holes. The mounting holes are arranged in the middle of the guide plates. The guide grooves and the guide plates are in guiding cooperation. The central points of the mounting holes and the positioning holes are located on the same straight line.

[0006] Further, the first frame body is further provided with a sliding groove and a guide rod connecting plate. The sliding groove is arranged at the bottom of the first frame body and is in sliding fit with the fixed frame. The guide rod connecting plate is arranged in the middle of the first frame body.

The openings of a plurality of the first guide rods face downward, and the openings of a plurality of the second guide rods face upward.

[0008] Further, the second frame body is further provided with a supporting plate and a pressing rod. The supporting plate is arranged in the middle of the second frame body and is in supporting cooperation with the side of the filter medium. The pressing rod is connected to the upper part of the second frame body and presses and limits both sides of the filter medium.

[0009] Further, the limiting assembly includes a limiting seat, at least one group of elastic members, a pushing plate, a connecting frame and a pressing wheel. The limiting seat is arranged at the bottom of the outer frame. The limiting seat is provided with at least one group of limiting holes.

Subsequently, after the second frame body on the other side is guided and installed on the first frame body, the push plate and the elastic component on the other side push against the fixed frame, and cooperate with the pressing wheel and the sliding groove to achieve limiting in the X, Y, and Z axis directions; the uniform distribution component adopts a uniform distribution film and a uniform flow net structure. The uniform distribution film adjusts the gas flow rate through the micropores on the film. By adjusting the micropore size, the gas flow rate at the position with a large air volume in the middle is slowed down, and the blocked gas flows out from the places with relatively small wind force on the four sides of the uniform distribution film, thereby realizing uniform gas outflow, and at the same time not affecting the pressure loss during the gas flow of the filtration system. The uniform flow net is used to support the uniform distribution film without affecting the air flow rate through the equally spaced ventilation holes, making the gas outflow more uniform.

[0022] As Figures 1 to 8 shown, in this embodiment, the utility model includes an outer frame 1, a filter medium 2, at least two groups of limit components 3 and a uniform distribution component 4. A plurality of the limit components 3 are symmetrically arranged at the bottom of the outer frame 1 along the length direction of the outer frame 1. The outer frame 1 is provided with a guide rod group 5 along the width direction. The filter medium 2 is arranged along the length direction of the outer frame 1 and is guided and limited by the guide rod group 5. The two sides of the outer frame 1 and the filter medium 2 are pressed and limited. The uniform distribution component 4 includes a fixed frame 41, a uniform distribution film 42 and a pressing plate 43. The fixed frame 41 is slidably matched with the outer frame 1 and is pushed and limited by the limit components 3. The uniform distribution film 42 is arranged on one side of the fixed frame 41. The fixed frame 41 is formed with a pressing groove 44. The pressing plate 43 is connected to the four sides of the uniform distribution film 42 and is limitedly matched with the pressing groove 44. The pressing plate 43 is correspondingly pressed and limited by a plurality of the limit components 3. The outer frame 1 is rectangular, and a square groove for air flow is formed in the middle;

[0023] The filter medium 2 is non-woven fabric. The cross section of the filter medium 2 is wavy. Cooperating with the first guide rod 51 and the second guide rod 52 arranged at intervals up and down, the contact area with water or air can be increased. Compared with a flat filter screen, there are more mesh holes, the filtration efficiency is improved, and because the number of mesh holes increases, the service time of the filter screen can be extended and the maintenance frequency can be reduced;

[0024] The uniform distribution component 4 adopts a structure of a uniform distribution film 42 and a uniform flow net 45. The uniform distribution film 42 adjusts the gas flow through the micropores on the film. By adjusting the micropore size, the gas flow rate at the position with a large air volume in the middle is slowed down. The blocked gas flows out from the places with relatively small wind force on the four sides of the uniform distribution film 42, so as to realize uniform gas outflow. At the same time, it does not affect the pressure loss in the gas flow process of the filtration system. The uniform flow net 45 is used to support the uniform distribution film 42 without affecting the air flow rate through the equally spaced ventilation holes, so that the gas outflow is more uniform;

[0025] The limit component 3 is installed and disassembled in cooperation with the chute 111. During installation, the fixed frame 41 enters the outer frame 1 along the direction of the chute 111. The push plate 33 and the elastic member 32 on one side push against the fixed frame 41. The pressing wheel 35 applies a downward pressure to the pressing plate 43, so that the uniform distribution film 42 is tightly fixed on the fixed frame 41 to achieve preliminary limiting. Subsequently, after the second frame body 12 on the other side is installed and guided to the first frame body 11, the push plate 33 and the elastic member 32 on the other side push against the fixed frame 41, and in cooperation with the pressing wheel 35 and the chute 111, limiting in the X, Y, and Z axis directions is achieved.

[0026] In this embodiment, the outer frame 1 is provided with two groups of first frame bodies 11 and two groups of second frame bodies 12. The two groups of first frame bodies 11 are detachably connected to the two groups of second frame bodies 12. The guide rod group 5 is arranged between the two groups of first frame bodies 11. Both groups of first frame bodies 11 are slidably matched with the fixed frame 41. A plurality of limit components 3 are correspondingly arranged at the bottoms of the two groups of second frame bodies 12. Both ends of the first frame body 11 are provided with guide grooves 13 and positioning holes 14. The positioning holes 14 are correspondingly arranged in the middle of the guide grooves 13. Both ends of the second frame body 12 are provided with guide plates 15 and mounting holes 16. The mounting holes 16 are arranged in the middle of the guide plates 15. The guide grooves 13 are in guiding cooperation with the guide plates 15. The central points of the mounting holes 16 and the positioning holes 14 are located on the same straight line. The mounting holes 16 and the positioning holes 14 are connected and fixed by a locking plug 17. The locking plug 17 is made of rubber material and has a certain elasticity. A limit ring is provided at the lower end of the locking plug 17. The diameter of the limit ring is larger than the diameters of the mounting holes 16 and the positioning holes 14. During installation, the locking plug 17 is squeezed so that it passes through the mounting holes 16 and the positioning holes 14 until the upper part of the locking plug 17 fits against the first frame body 11. At this time, the limit ring at the lower part of the locking plug 17 locks and limits the second frame body 12, so that the first frame body 11 and the second frame body 12 are connected and limited. A slot is formed in the side wall of the first frame body 11. The slot is used for quickly putting in and taking out the filter material 2, which is convenient for the daily maintenance of the filter material 2.

[0027] In this embodiment, the first frame body 11 is further provided with a chute 111 and a guide rod connecting plate 112. The chute 111 is arranged at the bottom of the first frame body 11 and is slidably matched with the fixed frame 41. The guide rod connecting plate 112 is arranged in the middle of the first frame body 11. The guide rod connecting plate 112 forms a connecting surface 113. The guide rod group 5 is fixedly connected to the connecting surface 113. The chute 111 forms a bayonet, and the bayonet is arranged at the front end of the chute 111 and is in limiting cooperation with the fixed frame 41.

[0028] In this embodiment, the guide rod group 5 is provided with a plurality of first guide rods 51 and a plurality of second guide rods 52. A plurality of the first guide rods 51 are fixedly connected to the guide rod connecting plate 112 at equal intervals, and a plurality of the second guide rods 52 are fixedly connected to the upper part of the first frame 11 at equal intervals. A plurality of the second guide rods 52 are correspondingly arranged between adjacent two groups of the first guide rods 51. Both the first guide rod 51 and the second guide rod 52 are in a C shape. The openings of a plurality of the first guide rods 51 face downward, and the openings of a plurality of the second guide rods 52 face upward. The first guide rod 51 bends upward, and the second guide rod 52 bends downward, alternately forming a wavy channel to provide a supporting and positioning effect on the wavy filter medium 2 and keep it wavy under the condition of strong wind.

[0029] In this embodiment, the second frame 12 is further provided with a support plate 121 and a pressing rod 122. The support plate 121 is arranged in the middle of the second frame 12 and is in supporting cooperation with the side of the filter medium 2. The pressing rod 122 is connected to the upper part of the second frame 12 and presses and limits both sides of the filter medium 2. The pressing rod 122 is in a C shape, and the opening of the pressing rod 122 faces upward. The pressing rod 122 presses and limits the filter medium 2 placed in cooperation with the support plate 121, and cooperates with the first guide rod 51 and the second guide rod 52 to support, so that the filter medium 2 remains stable during air filtration and improves the effectiveness of air filtration.

[0030] In this embodiment, the limiting assembly 3 includes a limiting seat 31, at least one group of elastic members 32, a push plate 33, a connecting frame 34 and a pressing wheel 35. The limiting seat 31 is arranged at the bottom of the outer frame 1. The limiting seat 31 is provided with at least one group of limiting holes 36. A plurality of the elastic members 32 are correspondingly arranged in a plurality of the limiting holes 36. One side of the push plate 33 is correspondingly connected to a plurality of the elastic members 32, and the other side of the push plate 33 is in top-pushing and limiting with the fixed frame 41. The connecting frame 34 is arranged on the upper part of the limiting seat 31. The connecting frame 34 is formed with a protruding part 37. The pressing wheel 35 is rotatably connected to the protruding part 37 and is in pressing and limiting with the pressing plate 43. The elastic member 32 is a spring. The limiting seat 31 is welded and fixed in the second frame. The pressing wheel 35 is made of rubber material and has a certain elasticity. The elastic member 32 cooperates with the push plate 33 to form a lateral thrust on the fixed frame 41, realizing top-pushing and limiting on both sides, ensuring that the uniform distribution film 42 of the uniform distribution assembly 4 is located in the middle of the outer frame 1 and improving the effect of uniform air flow out. The pressing wheel 35 applies a downward pressing force to the pressing plate 43, so that the uniform distribution film 42 is pressed and fixed on the fixed frame 41, avoiding the deviation of the uniform distribution film 42 caused by high-pressure air flow and affecting the air flow equalization efficiency.

[0031] In this embodiment, the fixed frame 41 is provided with a flow equalizing net 45. The flow equalizing net 45 is arranged in the middle of the fixed frame 41. The flow equalizing net 45 is formed with a plurality of equally spaced air holes.
