Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a frame for fixing a filter screen and an air processing device. Background Art

[0002] Traditional central air conditioning units need to be equipped with a filter inside to filter the air. Since the air flow inside the central air conditioning unit is relatively large, a single filter cannot meet the flow requirements. Since it is necessary to ensure that the filter does not deform too much when air flows through it, the area of ​​the single filter cannot be further increased. Therefore, the frame of the fixed filter of the existing central air conditioning unit can be spliced ​​with multiple frame units. A single frame unit is generally rectangular and a filter can be installed on it. Multiple frame units can be spliced ​​horizontally and vertically to form a total frame, so as to achieve the required total filtering area of ​​the filter.

[0003] At present, the above-mentioned assembled total frame has the following shortcomings: when the single frame units are connected and assembled to form the total frame of the entire large-sized filter wall, except for the frame units located at the edge, the four sides of the other frame units need to be spliced ​​with other frame units, and there are gaps at the splicing points, so that at least 4 air leakage gaps will be formed on the four sides, which will easily lead to the problem of air leakage. The total frame of the entire large-sized filter wall structure composed of single small-sized rectangular frame units connected to each other does not have sufficient rigidity, and will be distorted and deformed when the wind blows, and even cause the structure to collapse. It is necessary to add crossbeams and vertical beams on the back of the total frame to reinforce the frame units. This method has low installation efficiency and high cost. In addition, the frame unit is the smallest unit. Due to its rectangular shape, the volume occupied is relatively large, and too many small-sized frame units cannot be efficiently packaged and transported. Utility Model Content

[0051] In order to solve the problem of too many air leakage gaps between frame units when the frame units are assembled, a frame 1 for fixing the filter screen is proposed in the embodiment of the present application. Figure 2 This is a schematic diagram of the structure of a frame for fixing the filter screen in an embodiment of the utility model. Figure 3 Schematic diagram of the structure of the frame unit in the embodiment of the utility model, as shown in Figure 2 and Figure 3As shown, the frame 1 for fixing the filter net may include: at least two frame units 10. One frame unit 10 may be connected to an adjacent frame unit 10 to form an integral frame 1 for fixing the filter net.

[0052] Figure 4 This is a schematic diagram of the structure of the vertical beam of the frame unit in the embodiment of the utility model. Figure 5 Schematic diagram of the structure of the crossbeam of the frame unit in the embodiment of the utility model, as shown in Figures 2 to 5 As shown, the frame unit 10 may include: a first vertical beam 101 and a second vertical beam 102 arranged in parallel; a first horizontal beam 103 connecting the upper ends of the first vertical beam 101 and the second vertical beam 102; a second horizontal beam 104 connecting the lower ends of the first vertical beam 101 and the second vertical beam 102; and at least one third horizontal beam 105, the two ends of the third horizontal beam 105 respectively connecting the first vertical beam 101 and the second vertical beam 102, and the third horizontal beam 105 is located between the first vertical beam 101 and the second vertical beam 102. It should be noted that the vertical beam may extend in the vertical direction, and the horizontal beam may extend in the horizontal direction; in other embodiments, the horizontal beam may extend in the vertical direction, and the vertical beam may extend in the horizontal direction.

[0053] The frame unit 10 is connected to the second vertical beam 102 of the adjacent frame unit 10 via the first vertical beam 101, thereby forming an integral frame 1 for fixing the filter screen.

[0054] In the above structure, since each frame unit 10 has at least one third crossbeam 105, the space between the first crossbeam 103 and the second crossbeam 104 has been divided into a plurality of areas for installing the filter screen by the third crossbeam 105. Therefore, when forming an integral frame 1 for fixing the filter screen, the frame unit 10 only needs to be spliced ​​on the side of the first vertical beam 101 or the second vertical beam 102, and there is no need to splice on the side of the first crossbeam 103 and the second crossbeam 104. In this way, during splicing, only a gap may be generated between the first vertical beam 101 and the second vertical beam 102, and no gap will be generated at the first crossbeam 103 and the second crossbeam 104, which greatly reduces the number of air leakage gaps formed between the frame units 10 during assembly, and the possibility of air leakage and the amount of air leakage can be effectively reduced.

[0055] Specifically, for each frame unit 10, the area between the first vertical beam 101, the second vertical beam 102, the first cross beam 103 and the third cross beam 105 forms a filter installation space 107 or a sealing plate installation space. The area between the first vertical beam 101, the second vertical beam 102, the second cross beam 104 and the third cross beam 105 forms a filter installation space 107 or a sealing plate installation space.

[0056] When the number of the third cross beams 105 is greater than or equal to two, the first vertical beam 101, the second vertical beam 102 and the area between two adjacent third cross beams 105 form a filter installation space 107 or a sealing plate installation space.

[0057] Each of the above-mentioned filter installation spaces 107 can be installed with a filter, and multiple filters can be installed on the entire frame 1 for fixing the filter, and all the filters can filter the air flowing through. The sum of the areas of multiple filters can reach the required total filter area of ​​the filter. When the sum of the areas of multiple filters has reached the required total filter area of ​​the filter, the area at the edge of the frame can be used as a sealing plate installation space, and the sealing plate installation space is used to install the sealing plate, so as to block the sealing plate installation space. In addition, the length and width of the filter can be a limited model, and the remaining vertical beam direction dimensions at both ends after the filter located in the middle is arranged may not be able to install a filter of the minimum size specification. At this time, the area can be used as a sealing plate installation space, and the sealing plate is used to block it later. As a feasible method, the connection between the first crossbeam 103, the second crossbeam 104, and the third crossbeam 105 at both ends and the first vertical beam 101 and the second vertical beam 102 can be a splicing connection. In this way, each cross beam and vertical beam in the frame unit 10 can be spliced ​​at the installation site of the air handling device or the production site of the air handling device to form a spliced ​​frame unit 10. Through the above structure, each cross beam and vertical beam in the frame unit 10 is in a straight strip shape, all cross beams have the same basic length, and all vertical beams have the same basic length, which is convenient for efficient transportation after stacking and bundling, thereby reducing transportation costs. After the cross beams and vertical beams are transported to the destination, they are spliced ​​and installed to form a spliced ​​frame unit 10.

[0058] In a specific splicing connection mode, the two ends of the first cross beam 103, the second cross beam 104, and the third cross beam 105 are spliced ​​and connected to the first vertical beam 101 and the second vertical beam 102 respectively through the buckle structure 106. This splicing connection can greatly improve the speed and convenience of splicing.

[0059] In a specific splicing connection mode, the two ends of the first horizontal beam 103, the second horizontal beam 104, and the third horizontal beam 105 are spliced ​​and connected to the first vertical beam 101 and the second vertical beam 102 respectively by means of screw and nut matching or bolt and nut matching. This splicing connection can greatly improve the firmness of the splicing.

[0060] In other feasible implementations, the above two splicing connection methods may also be used simultaneously.

[0061] Similarly, the frame unit 10 can be connected to the second vertical beam 102 of the adjacent frame unit 10 by splicing through the first vertical beam 101, so that the frame units 10 are spliced ​​to form a complete frame 1 for fixing the filter screen.

[0062] As a feasible method, the frame unit 10 can be connected in a splicing manner through the first vertical beam 101 and the second vertical beam 102 of the adjacent frame unit 10 by means of a connection method in which screws and nuts cooperate or a connection method in which bolts and nuts cooperate. This splicing method has low cost, is easy to implement on site, and can be disassembled again later. Specifically, the first vertical beam 101 includes a first vertical beam body 1011 and a first vertical beam first flange 1012 located at the edge of the length. The second vertical beam 102 includes a second vertical beam 102 body and a second vertical beam 102 first flange located at the edge of the length. Holes for screws or nuts to pass through can be processed in advance on the first vertical beam body 1011 and the second vertical beam 102 body, so as to facilitate the splicing connection by workers later.

[0063] As feasible, the first beam 103 includes a first beam body 1031, a first beam first flange 1032 located at one end width edge, a first beam second flange 1033 located at another end width edge, and a first beam third flange 1034 located at a length edge. The flanges are all facing the same direction.

[0064] As for the method of achieving splicing connection through the snap-fit ​​structure 106, it is feasible that the first flange 1032 of the first horizontal beam is spliced ​​and connected with the first vertical beam body 1011 through the snap-fit ​​structure 106, and the second flange 1033 of the first horizontal beam is spliced ​​and connected with the second vertical beam 102 body through the snap-fit ​​structure 106.

[0065] Regarding the splicing connection achieved by means of a screw and nut connection method or a bolt and nut connection method, it is feasible that the third flange 1034 of the first horizontal beam is spliced ​​and connected with the first flange 1012 of the first vertical beam by means of a screw and nut connection method or a bolt and nut connection method, and the third flange 1034 of the first horizontal beam is spliced ​​and connected with the first flange of the second vertical beam 102 by means of a screw and nut connection method or a bolt and nut connection method.

[0066] Similarly, as feasible, the second beam 104 includes a second beam 104 body, a first flange of the second beam 104 located at an edge of one end width, a second flange of the second beam 104 located at an edge of the other end width, and a third flange of the second beam 104 located at an edge of the length.

[0067] As for the method of achieving splicing connection through the snap structure 106, it is feasible that the first flange of the second cross beam 104 is spliced ​​and connected with the first vertical beam body 1011 through the snap structure 106, and the second flange of the second cross beam 104 is spliced ​​and connected with the second vertical beam 102 body through the snap structure 106.

[0068] Regarding the splicing connection achieved by means of a screw and nut connection method or a bolt and nut connection method, it is feasible that the third flange of the second horizontal beam 104 is spliced ​​and connected with the first flange 1012 of the first vertical beam by means of a screw and nut connection method or a bolt and nut connection method, and the third flange of the second horizontal beam 104 is spliced ​​and connected with the first flange of the second vertical beam 102 by means of a screw and nut connection method or a bolt and nut connection method.

[0069] As a feasible method, the third cross beam 105 is formed by splicing two third cross beam members 1051. The general structure of the third cross beam member 1051 can be substantially the same as that of the first cross beam 103 or the second cross beam 104.

[0070] Specifically, the third cross beam 1051 includes a third cross beam 1051 body, a first flange of the third cross beam 1051 located at the edge of the width of one end, a second flange of the third cross beam 1051 located at the edge of the width of the other end, and a third flange of the third cross beam 1051 located at the edge of the length. The first flange of the third cross beam 1051, the second flange of the third cross beam 1051, and the third flange of the third cross beam 1051 are all facing the same side. Through this structure, the structure of the third cross beam 1051 is the same as that of the first cross beam 103 and the second cross beam 104, so all the components of the cross beams can be the same universal component.

[0071] In order to splice two third cross beams 1051 to form the third cross beam 105, it is feasible that the two third cross beams 1051 are placed with the sides of the third cross beams 1051 bodies without flanges and spliced ​​together by a connection method of screws and nuts or a connection method of bolts and nuts. Since the third cross beam 105 is spliced ​​first, the third cross beams 1051 bodies can be as tightly fitted as possible to minimize the size of the gap, or a seal can be added between the two.

[0072] Regarding the method of achieving splicing connection through the snap-fit ​​structure 106, it is feasible that the first flanges of the third cross beam members 1051 of the two third cross beam members 1051 are spliced ​​and connected with the first vertical beam body 1011 through the snap-fit ​​structure 106, and the second flanges of the third cross beam members 1051 of the two third cross beam members 1051 are spliced ​​and connected with the first vertical beam body 1011 through the snap-fit ​​structure 106.

[0073] Regarding the splicing connection achieved by means of a screw-nut connection or a bolt-nut connection, it is feasible that the third flanges of the third cross beam members 1051 of the two third cross beam members 1051 are spliced ​​and connected with the first flange 1012 of the first vertical beam by means of a screw-nut connection or a bolt-nut connection, and the third flanges of the third cross beam members 1051 of the two third cross beam members 1051 are spliced ​​and connected with the first flange of the second vertical beam 102 by means of a screw-nut connection or a bolt-nut connection.

[0074] In order to make the flanges of the horizontal beam and the vertical beam fit closely with the filter screen, thereby reducing the amount of air leakage, as a feasible method, the first vertical beam 101 has a depression 1013 at the first flange 1012 of the first vertical beam connecting the first horizontal beam 103, the second horizontal beam 104 and the third horizontal beam 105, and the depression 1013 is used to accommodate the third flange of the horizontal beam, so that the first flange 1012 of the first vertical beam is flush with the third flange of the horizontal beam for installing the filter screen. The second vertical beam 102 has a depression 1013 at the first flange of the second vertical beam 102 connecting the first horizontal beam 103, the second horizontal beam 104 and the third horizontal beam 105, and the depression 1013 is used to accommodate the third flange of the horizontal beam, so that the first flange of the second vertical beam 102 is flush with the third flange of the horizontal beam for installing the filter screen.

[0075] Furthermore, when the first flange 1012 of the first vertical beam, the first flange of the second vertical beam 102 and the third flange of the horizontal beam are spliced ​​and connected by means of screws and nuts or bolts and nuts, the screws and bolts can be countersunk type to avoid protrusions, so that the flange of the horizontal beam can fit tightly against the filter net.

[0076] The present application also proposes an air treatment device, Figure 1 FIG. 1 is a schematic diagram of the structure of an air treatment device having a frame for fixing a filter screen in an embodiment of the utility model. Figure 1 As shown, the air handling device comprises: a frame 1 for fixing a filter as described above; and a plurality of filters mounted on the frame 1 for fixing the filter. The frame is used to be mounted in the filter section of the air handling device.

[0077] As a feasible method, the frame 1 for fixing the filter screen can be connected and fixed to the housing of the air handling device by screws or nuts, etc., by using the holes originally processed in advance on the first vertical beam 101 and the second vertical beam 102 for screws or nuts to pass through.
