Description

Glove box filter Technical Field

[0001] This utility model relates to the field of glove box equipment technology, specifically to glove box filters. Background Technology

[0002] As a closed operating device, glove boxes are widely used in laboratories, pharmaceutical production, and semiconductor processing. The cleanliness of their internal environment directly affects process quality and operational safety. Traditional glove box filters mostly adopt an integrated filter structure, with the filter screen fixed inside the filter unit. This means that replacing the filter screen requires disassembling the entire filter module or even stopping the machine, making the maintenance process cumbersome and time-consuming. Therefore, we propose the glove box filter. Summary of the Invention

[0009] Preferably, the pressure strip is arc-shaped, with its middle part corresponding to the tail end of the connecting column and screwed together by a threaded hole, so that both sides of the pressure strip are tightly attached to the filter screen unit.

[0010] Preferably, the annular array spacing of the connecting columns matches the sector angle of the filter unit to ensure that adjacent filter units form a continuous filter surface after being spliced ​​together.

[0011] Preferably, the cylinder includes an air inlet end and an air outlet end connected at both ends, and the air outlet end is provided with an air hole for exhausting air.

[0012] Preferably, the end of the air intake pipe extends outward toward the air intake end until the outer side of the air intake end connects with the air duct.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Referring to Figures 1-5, the glove box filter includes a cylinder 1 connected to the glove box, wherein the two ends of the cylinder 1 are sealed by an air inlet 11 and an air outlet 12. An air inlet pipe 2 is installed in the cylinder 1 along its axial direction, wherein one end of the air inlet pipe 2 extends outward toward the air inlet 11 until it communicates with the air duct on the outside of the air inlet 11. The air outlet 12 is provided with an air hole 13 for exhausting air, and the air holes 13 are distributed in a circular array around its axis, and a seal is left at its axis position to close the other end of the air inlet pipe 2.

[0024] Multiple filter units 3 are provided along the axial direction of the intake pipe 2. Each filter unit 3 includes a connecting post 31. The head of the connecting post 31 is connected to the intake pipe 2 by a thread. Multiple connecting posts 31 are connected in a ring on the intake pipe 2. A filter screen unit 32 is also provided between adjacent connecting posts 31. The filter screen unit 32 is connected to the intake pipe 2 and is located between adjacent connecting posts 31. A pressure strip 33 is provided at the tail end of the connecting post 31. The pressure strip 33 is fixed to the connecting post 31 by a nut. At the same time, both ends of the pressure strip 33 are pressed against the filter screen unit 32 to limit the position of the filter screen unit 32.

[0025] The filter unit 32 is arranged in a fan shape and includes a filter bag and a filter box with multiple through holes. The filter box includes a head and a tail that are interlocked with each other. The size of the filter box is consistent with the gap size between adjacent connecting posts 31. When the filter bag needs to be replaced, the head and tail of the filter box are separated and the filter bag is placed in it to complete the replacement.

[0026] During use, the air inlet 11 is connected to the air duct, and the air outlet 12 is connected to the glove box. When the air inlet 11 is connected to the air duct, the airflow enters from the air inlet pipe 2. Since the filter unit 3 is connected to the air inlet pipe 2, the airflow enters the filter screen unit 32. After being filtered by the filter bag in the filter screen unit 32, the airflow is discharged from the through hole of the filter box into the cavity of the cylinder 1 and discharged from the air hole 13 on the air outlet 12. Since the air outlet 12 of the cylinder 1 is connected to the cylinder 1, the filtered airflow can be introduced into the glove box.
