[0002] The single filter plate dust collector is a type of filter dust collector. It is a device that allows the dust-laden airflow to pass through the filter material to separate and capture the dust. This device mainly uses fiber non-woven fabrics as filter materials and is often used in the dust removal of industrial exhaust gas. Its dust removal efficiency can generally reach more than 99%. Although it is one of the oldest dust removal methods, it is increasingly widely used due to its high efficiency, stable and reliable performance, and simple operation.

[0053] In this embodiment, when the filter plate dust collector is back-blown, compressed gas enters from the air outlet of the upper filter head, and the airflow is divided into two streams by the clips and enters the independent cavities on both sides respectively, so that the airflow acts on the filter paper 2 more evenly and powerfully, and the dust is cleaned more thoroughly;

[0054] The two filter papers 2 fit tightly against the clip 3 and are bonded together by adhesives such as glue, adhesive strips, and adhesive dots, so that the filter papers 2 fit more tightly and are more firmly bonded. During use, the filter papers 2 will be subjected to a certain amount of pressure, and the clip 3 plays a role of reinforcing support between the two filter papers 2, thereby improving the pressure resistance of the filter papers 2.

[0055] It also includes a mounting frame 1, two filter papers 2 are sealed and arranged on the inner side of the mounting frame 1, and the two filter papers 2 are arranged opposite to each other; a tightening device 4 is arranged on the mounting frame 1, and the tightening device 4 includes: a slide 401, which is slidably arranged on the mounting frame 1; a tightening member 402, which is arranged on the slide 401, and the tightening member 402 has a clamping portion 4021, which abuts against the filter paper 2, and corresponds to the position of the clamping piece 3 after sliding.

[0056] In this embodiment, a filter paper 2 is sealed and arranged on both sides of the mounting frame 1 in the length direction; each filter paper 2 is folded into a pointed wave shape; the upper and lower sides of each filter paper 2 are sealed and connected to the mounting frame 1 through a glue injection filter head, and the left and right sides of each filter paper 2 are sealed and connected to the mounting frame 1 through ultrasonic welding; a tightening device 4 is installed in the length direction of the mounting frame 1; the cross-section of the clamping part 4021 is a right-angled triangle structure, and the chamfer at the right angle tip is in the shape of an arc; when the operator seals the two filter papers 2 on both sides of the length direction of the mounting frame 1, the two filter papers 2 are adhered together by gluing, at this time, the clamping part 4021 and the folded groove of the filter paper 2 are in contact, and the operator drives the slide 401 to slide on the mounting frame 1, so that the two filter papers fit each other more closely and firmly, and prevent the two filter papers from separating due to loose adhesion.

[0057] This air filter element is used in conjunction with a stand-alone filter plate dust collector. The operator connects the assembled air filter element to the inside of the stand-alone filter plate dust collector along the height direction of the stand-alone filter plate dust collector through bolts. When the gas mixed with dust enters the inside of the stand-alone filter plate dust collector, the airflow passes through the filter papers 2 on both sides of the air filter element respectively. At this time, the filter papers 2 on both sides adsorb the dust in the airflow on the outer surface, and then the filtered airflow flows upward from between the two filter papers 2.

[0058] Furthermore, the mounting frame 1 includes: an upper filter head 101, having an air outlet 1011, and the air outlet 1011 is connected to the two filter papers 2; an edge seal 102, having two groups, and one end of the two groups of edge seals 102 are relatively arranged on both sides of the upper filter head 101; and a lower filter head 103, and both sides of the lower filter head 103 are respectively arranged at the other ends of the two groups of edge seals 102.

After the single-machine filter plate dust collector has been used for a period of time, a large amount of dust is accumulated on the outer surface of the air filter element. At this time, the operator drives the pulse dust cleaning spraying system on the single-machine filter plate dust collector to allow compressed air to enter the interior of the air filter element from the air outlet 1011 of the upper filter head 101. At this time, the filter papers 2 on both sides of the mounting frame 1 are affected by the compressed air in the middle and bulge to both sides respectively, shaking off the dust on the outer surface.

[0060] Furthermore, the clip 3 is located between the two groups of edge sealing 102 .

[0061] In this embodiment, the clip 3 is in the shape of a flat plate; the two sides of the clip 3 in the length direction are arranged between the two sets of edge sealing 102 by ultrasonic welding, and the two sides of the clip 3 in the width direction are sealed by the middle part of the upper filter head 101 and the middle part of the lower filter head 103 respectively, and have good sealing performance.

[0063] In this embodiment, the plug-in portion 6 is in a folded line shape, and the plug-in slot 1021 is adapted to the plug-in portion 6; the plug-in portions 6 are folded on both sides of the length direction of each filter paper 2, and the plug-in portion 6 is supported by a metal strip, and the plug-in portion 6 and the plug-in slot 1021 are snap-fitted, so that the two filter papers 2 are respectively sealed and arranged on both sides of the mounting frame 1. It can be additionally configured that the plug-in slot 1021 and the plug-in portion 6 are both friction surfaces, which ensures the stability of the plug-in portion 6 and the plug-in slot 1021 after plugging and fitting, and ensures that the filter paper 2 is sealed and arranged on the mounting frame to prevent air leakage.

[0064] Furthermore, it also includes: two adhesive layers 301 , the two adhesive layers 301 are respectively arranged on both sides of the clip 3 , and the two adhesive layers 301 are respectively attached to the two filter papers 2 .

[0065] In this embodiment, the adhesive layer 301 allows the two filter papers 2 to be respectively arranged on both sides of the clip 3, so that each filter paper 2 can fit tightly to the two sides of the clip 3, ensuring the stability of the air filter element structure. The adhesive layer 301 can be formed by items with adhesive functions such as adhesive strips and glue. The adhesive layer 301 can be in various forms such as strips and dots in a plane.

[0066] Furthermore, the adhesive layer 301 has a plurality of adhesive strips, and the plurality of adhesive strips are arranged on the clip 3 in an array parallel to the sliding direction of the slide seat 401 .

[0067] In this embodiment, the adhesive layer 301 uses a plurality of adhesive strips to bond the filter paper 2 and the clip 3 together. The adhesive strips increase the contact area between the filter paper 2 and the clip 3, further ensuring the stability of the air filter element structure.

[0068] Furthermore, the outer side of the edge banding 102 has a slide groove, and the tightening device 4 also includes: the slide seat 401 includes: two sliders 4011, and the two sliders 4011 are respectively slidably set on the slide grooves on both sides; there are two fixing rods 403, and the two fixing rods 403 are respectively set on both sides of the mounting frame 1, and the fixing rod 403 is connected to the two sliders 4011; there are a plurality of tightening members 402, and the plurality of tightening members 402 are arranged on the fixing rod 403 along the axial array of the fixing rod 403.

[0069] In this embodiment, after the operator has installed the air filter element, the operator can slide the slide seat 401 to allow the plurality of pressing members 402 to slide upward or downward along the height direction of the air filter element, so that the adhesion between the filter paper 2 and the clip 3 is more stable.

[0070] Furthermore, the tightening device 4 also includes: each of the sliders 4011 has a threaded hole 404; there are two fixing bolts 405, and each of the threaded holes 404 is threadedly connected with a fixing bolt 405, and the fixing bolt 405 is used to fix the slider 4011.

[0071] In this embodiment, after the operator drives the slide 401 to make the tightening part stick to the sticking part of the filter paper 2 and the clip 3 better, the slide 401 can be fixed to the side of the edge seal 102 by using the fixing bolt 405. At this time, the tightening part of the tightening member 402 is opposite to the sticking part between the filter paper 2 and the clip 3 to prevent the filter paper 2 and the clip 3 from separating.

[0072] Furthermore, the tightening device 4 also includes: a plurality of blocking rods 406, and the blocking rods 406 are arranged on both sides of the mounting frame 1. The blocking rods 406 are connected to the slider 4011, and the blocking rods 406 are arranged on both sides of the fixed rod 403 along the sliding direction of the slide seat 401.

[0073] In this embodiment, when the pulse cleaning spray system of the single-machine filter plate dust collector is started, the filter paper 2 on both sides of the filter element will bulge. At this time, the outer surfaces of the bulged filter papers 2 on both sides collide with the blocking rod 406, thereby increasing the vibration amplitude of the filter paper 2 and making the dust on the outer surface of the filter paper 2 more effectively shaken off.

[0074] Furthermore, the tightening device 4 has a plurality of slide seats 401 , and the plurality of tightening device 4 slide seats 401 are arranged in an array in a sliding direction on the mounting frame 1 .

[0075] In this embodiment, a plurality of tightening devices 4 cause different areas of the outer surface of the filter paper 2 on both sides to collide with the blocking rod 406, thereby improving the efficiency of cleaning. At the same time, each tightening member 402 in the plurality of tightening devices 4 presses different sticky parts of the filter paper 2 and the clip 3 to prevent the filter paper 2 and the clip 3 from separating.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
