DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0019] like Figure 1 and Figure 2As shown, a filter for clean rooms includes a filter element, a gas pipeline and an exhaust pipeline; a valve port 3 is installed at the gas delivery port of the gas pipeline 4, and two groups of gas pipelines 4 are connected through a joint pipeline 7. The joint pipeline 7 is provided with two groups of exhaust pipelines 8 in the horizontal direction, and a material receiving pipeline 6 is connected to the bottom of the exhaust pipeline 8. A recovery bag 11 is installed in the material receiving pipeline 6, and the recovery bag 11 is connected to the filter element 13, and the filter element 13 is installed between the valve port 3 and the joint pipeline 7. Among them, the gas pipeline 4 is divided into two groups of left and right horizontal structures, and the horizontal installation process is completed through the joint pipeline 7. When in use, the gas pipeline to be filtered can be connected to the gas supply of the gas pipeline 4, and the filter element 13 built into the gas pipeline 4 can be used to complete the further filtering process. However, in the process of long-term filtering, the filter element 13 needs to be replaced according to the demand. Because it is a double-pipeline structure, the gas pipelines 4 on the left and right sides can be used intermittently. At the same time, if the filtering demand is large, the double pipeline can also be used to carry out the gas filtering process at the same time. The joint pipeline 7, which serves as a supporting structure, has an exhaust pipeline 8 at its own level, and utilizes two sets of exhaust pipelines 8 to solve the post-filter gas exhaust process.

[0020] like Figure 1 and Figure 2 As shown, the joint pipeline 7 is fixedly installed with connecting plates 1 on both sides, and a horizontal axis 2 is inserted horizontally on the top of the connecting plate 1. The horizontal axis 2 belongs to the air conditioner positioning and installation structure. The joint pipeline 7 uses the connecting plate 1 and the horizontal axis 2 to complete the mounting process.

[0021] like Figure 1 and Figure 2 As shown, the outer side of the filter element 13 and the recovery bag 11 is equipped with a support grid 9, and two sets of support grids 9 are fixedly mounted on the inner wall of the gas transmission pipeline 4 and the inner wall of the material receiving pipeline 6 respectively. Among them, the recovery bag 11 and the filter element 13 are in a connected structure, and the large particles and impurities that cannot be attached to the inside of the filter element 13 can be collected by negative pressure collection in the later stage. The support grid 9 plays a role in structural protection, preventing the internal filter element 13 and the recovery bag 11 from being ruptured due to external impact during use.

[0022] like Figure 1 and Figure 2 As shown, the connection between the filter element 13 and the recovery bag 11 is provided with a bellows 10, and the bellows 10 has a docking hole along the exhaust pipe 8. The bellows 10 can change the bending angle at will, which also belongs to a set structure for protecting the pipeline.

[0023] like Figure 1 and Figure 2 As shown, a packaging cover 12 is installed at the bottom port of the recovery bag 11. The packaging cover 12 can prevent the airflow from overflowing from the recovery bag 11.

[0024] like Figure 1 and Figure 2 As shown, the material receiving pipeline 6 is connected to the negative pressure fan 5. The negative pressure fan 5 is a device responsible for recovering particulate impurities under negative pressure.

[0025] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
