Description

Technical Field

[0001] This utility model belongs to the field of air purification and filtration application technology, specifically relating to a primary air supply filter bag. Background Technology

[0002] Primary air supply filter bags are characterized by stable efficiency, low resistance, large dust holding capacity, good air velocity uniformity, and long service life. They are usually used in conjunction with corresponding air purification equipment to complete the initial adsorption filtration of incoming air.

[0003] Currently, the problems with pre-filter bags available in the traditional market are: they employ a structure of multiple filter bags with corresponding fixed frames, which in practice can obstruct the airflow, affecting the uniformity of the incoming air velocity and indirectly impacting the purification effect. Furthermore, using a single profile frame also results in a lack of strength.

[0004] Therefore, based on the above problems, this utility model provides a primary air supply filter bag. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a primary air supply filter bag to solve the problems existing in the current use of primary air supply filter bags.

[0006] Technical solution: The primary air supply filter bag provided by this utility model includes a first profile frame and a second profile frame. The first profile frame and the second profile frame are respectively provided with a first profile frame through groove and a second profile frame through groove. A filter bag is provided on one side of the first profile frame. The four corner end faces of the first profile frame and the second profile frame are respectively provided with a first profile frame screw groove and a second profile frame screw hole. The first profile frame and the second profile frame are fixed together by bolts through the first profile frame screw groove and the second profile frame screw hole.

[0007] In this technical solution, the first profile frame and the second profile frame have the same dimensions, and the through groove of the first profile frame and the through groove of the second profile frame have the same dimensions.

[0008] In this technical solution, the first profile frame and the second profile frame are any one of galvanized sheet, aluminum sheet, or alloy stainless steel sheet.

[0009] In this technical solution, the filter bag is a non-woven fabric filter bag or an activated carbon filter bag.

[0010] In this technical solution, the screw hole of the second profile frame is a countersunk screw hole.

[0011] Compared with the prior art, the beneficial effects of the primary air supply filter bag of this utility model are as follows: 1. The simplified structure of the profile frame, the removal of the fixed frame plate, and the use of a single large-size filter bag make the air velocity uniform and unobstructed, thereby improving the air intake purification efficiency; 2. The use of a two-part split combination structure, the first profile frame and the second profile frame, makes it convenient to remove and replace or clean the filter bag without affecting normal use. At the same time, the double profile frame increases the strength of the overall structure, making it less prone to deformation and more durable. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be noted that the terms "top," "bottom," "one side," "the other side," "front," "back," "middle part," "inner," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 The primary air supply filter bag shown is... Includes a first profile frame 100 and a second profile frame 200. The first profile frame 100 and the second profile frame 200 are respectively provided with a first profile frame through groove 102 and a second profile frame through groove 203. A filter bag 101 is provided on one side of the first profile frame 100. The first profile frame 100 and the second profile frame 200 are respectively provided with first profile frame screw grooves 103 and second profile frame screw holes 201 in the four corner end faces. The first profile frame 100 and the second profile frame 200 are fixed together by bolts 202 through the first profile frame screw groove 103 and the second profile frame screw hole 201.

[0017] The working principle or structural principle is as follows: (1) The second profile frame 200 is stacked on the side of the first profile frame 100 containing the first profile frame screw groove 103; (2) The filter bag 101 passes through the first profile frame groove 102; (3) Ensure that the screw holes of the second profile frame are aligned with the screw grooves of the first profile frame 103, and then tighten the bolts 202 to fix the first profile frame 100 and the second profile frame 200 together through the screw grooves of the first profile frame 103 and the screw holes of the second profile frame 201.

[0018] When the filter bag 101 needs to be cleaned or replaced after a period of use (regularly), the first profile frame 100 and the second profile frame 200 can be separated by unscrewing the bolt 202. At this time, the filter bag 101 can be removed along with the second profile frame 200, and the filter bag 101 can be cleaned or replaced as needed.

[0019] In addition, preferably, the first profile frame 100 and the second profile frame 200 are the same size, and the first profile frame through groove 102 and the second profile frame through groove 203 are the same size. Specifically, the height of the first profile frame 100 and the second profile frame 200 before assembly is pre-set and processed according to the installation occasion. After assembly, they can be normally matched and installed at the air outlet of the purification equipment. The first profile frame through groove 102 and the second profile frame through groove 203 with the same size do not affect the obstruction of air intake.

[0020] In addition, preferably, the first profile frame 100 and the second profile frame 200 are any one of galvanized sheet, aluminum sheet, or alloy stainless steel sheet. Specifically, the first profile frame 100 and the second profile frame 200 are selected according to the appropriate profile type based on the scene equipment to be installed.

[0021] In addition, the filter bag 101 is preferably a non-woven filter bag or an activated carbon filter bag. Specifically, the filter bag 101 is selected according to the appropriate filter bag type based on the scene equipment to be installed.

[0022] In addition, preferably, the screw hole 201 of the second profile frame is a countersunk screw hole, so that the bolt 202 does not protrude from the surface of the screw hole 201 of the second profile frame after assembly, which will affect the overall structural installation and compatibility.

[0023] This type of primary air supply filter bag is suitable for use in filtration systems in industrial cleanrooms such as fresh air systems, pharmaceuticals, coating, semiconductors, large-scale farms, and cleanrooms.
