Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to filter technology. Background Art

[0002] An air filter for wind power generation requires a large filtering area. Therefore, when the filter element assembly is a single piece, its volume is too large and heavy.

[0003] Since the filter for wind power generation is installed in a high-altitude environment, during high-altitude operations, the space for pulling out and inserting the filter element is limited, which is very unfavorable for disassembly and assembly. If it is made into a multi-side disassembly and assembly structure, it will increase the complexity of high-altitude operations, and the multi-side disassembly and assembly structure is complex and not conducive to actual use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pull-out filter adopting a filter element assembly structure to solve at least one of the above technical problems.

[0005] The technical problems solved by the utility model can be realized by adopting the following technical solutions:

[0006] A pull-out filter adopting a filter element assembly structure includes a mounting bracket. The mounting bracket includes an upper frame, a lower frame, a left frame, and a right frame. A guide rail is arranged between the left frame and the right frame. The guide rail includes an upper rail and a lower rail;

[0007] It further includes at least two filter elements;

[0008] The filter element is slidably connected to the guide rail;

[0009] The left frame is provided with an opening allowing the filter element to pass through, and a detachable fixing plate is arranged on the opening;

[0010] A snap-lock structure is arranged on both sides of the filter element. The snap-lock structure includes a long strip plate fixedly connected to the side. A chute is reserved between the long strip plate and the side of the filter element. The chute has a gap for accommodating the long strip plate of the adjacent filter element;

[0011] For two adjacent filter elements, the chute on the snap-lock structure of one filter element accommodates the long strip plate of the other filter element, forming a connection relationship that mutually locks and restricts left and right displacement.

[0012] In the above design, the four frames enclose to form a mounting bracket. A guide rail is arranged in the mounting bracket. The upper and lower ends of at least two filter elements are placed in the guide rail and can slide on the guide rail. The left frame is provided with an opening allowing the filter element to pass through.

[0013] In the above design, a snap-lock structure is provided on both sides of the filter element. The snap-lock structure includes a long strip. One side of the long strip is fixed to the side of the filter element, and a chute is left between the side of the filter element and the long strip. The reserved chute can accommodate the long strip on the side of the adjacent filter element. When the long strips of two adjacent filter elements are accommodated in the chute, the adjacent filter elements are restricted from moving left and right and can only be separated up and down.

[0014] Specific usage process: First, push the first filter element into the guide rail through the opening of the left frame, leaving one side of the filter element outside the left frame. The second filter element is placed from top to bottom, and the long strips of each other are placed into the chutes left by the other party. After docking, push the second filter element together with the previous one into the guide rail, and leave the side of the second filter element outside the left frame. Connect the subsequent filter element in the same way as the second filter element, and repeat until the guide rail is full of filter elements. Then insert the fixing plate into the card slot to enclose the filter elements in the guide rail.

[0015] When the filter element needs to be cleaned, first pull out the fixing plate upward from the card slot, then pull out the first filter element from the opening to the outside of the left frame, and then lift the filter element upward until the long strip on the side of the filter element is separated from the side of the subsequent filter element, completing the complete separation of the filter element; then continue to pull out the next filter element and repeat the separation action of the previous filter element until the last filter element is directly pulled out from the opening, completing the removal process of the filter element.

[0016] Furthermore, the lower rail of another guide rail is stacked on the upper rail of the guide rail to form a multi-layer guide rail structure.

[0017] In the above design, the guide rail is stacked on the guide rail to form a multi-layer guide rail structure. By using the multi-layer guide rail to separately arrange the filter elements, it helps to divide the single filter element into multiple filter elements, making the multiple filter elements smaller in size, lighter in weight, easier to disassemble and assemble, thus reducing the complexity of high-altitude operations.

[0018] Furthermore, pulleys are provided at the lower end of the filter element.

[0019] In the above design, pulleys are provided at the lower end of the filter element, which can make the filter element slide more easily on the guide rail and the extraction more labor-saving.

[0020] Furthermore, the width of the fixing plate is greater than the width of the opening allowing the filter element to pass through;

[0021] The detachable connection is a card slot connection;

[0022] The card slot is provided on the frame.

[0023] In the above design, the width of the fixing plate is greater than the width of the opening, which is used to enclose the filter element on the guide rail. The card slot structure can realize the detachable connection of the fixing plate on the frame, facilitating disassembly and assembly.

[0024] Furthermore, a handle is provided on the fixing plate.

[0025] In the above design, the handle is provided for two purposes. On the one hand, it facilitates the disassembly and assembly of the fixing plate. On the other hand, it allows the fixing plate to be placed using the handle.

[0026] Furthermore, a wire mesh is provided as an air filter element on the side of the guide rail where the air intake is located.

[0027] In the above design, the wire mesh serves as a primary air filter. Its beneficial effect is to protect the filter element, extend the service life of the filter element, and reduce the usage cost.

[0028] In the present utility model, a guide rail is provided inside the mounting bracket, a filter element is provided inside the guide rail, and a snap-lock structure is provided on both sides of the filter element. The snap-lock structure forms an inseparable connection relationship in the left-right direction and a separable relationship in the up-down direction. The inseparable connection relationship in the left-right direction enables the filter elements to be connected in series inside the guide rail, and pulling the outermost filter element can continuously take out all the filter elements inside the guide rail; the separable relationship in the up-down direction facilitates disassembly and assembly.

[0029] Its beneficial effect is that the filter element is split into multiple assembled filter elements, with a simple structure, reduced size, and lighter weight, making it easier to disassemble and assemble in the limited space at high altitude, reducing the complexity of high-altitude operations, and improving the disassembly and assembly efficiency of the filter.
