Description

Technical Field

[0001] This utility model relates to the technical field of laboratory computer room dust removal systems, and in particular to a laboratory computer room dust removal system. Background Technology

[0002] When conducting cleanroom experiments in a laboratory, a dust removal system is required to remove dust from the internal environment. In existing technologies, most methods employ negative pressure suction to circulate and refresh the gas within the laboratory. During the suction and exhaust process, filters such as screens or filter paper are used to filter and remove dust from the gas. Patent CN202410654086.3 discloses a dust removal structure for the air inlet of a cleanroom laboratory, specifically involving an axial flow fan installed inside the air inlet duct. This fan creates an airflow that carries dust, and a dust filter is used to filter and remove dust from the gas. The structure for cleaning the dust filter is also disclosed. However, in practical use, cleaning can cause scratches or deformation of the dust filter during cleaning. Especially under reverse airflow, the stress from repeated deformation can cause cracks at the joints of the warp and weft threads in the mesh, leading to a decrease in dust-proof effectiveness and a reduction in the cleanliness of the laboratory air. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing dustproof nets are scratched and deformed when dust is blown away, affecting the dust removal effect in the laboratory.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dust removal system for a laboratory computer room, including an axial flow fan, air inlet pipes installed on both sides of the axial flow fan, and a dust removal cylinder device installed on the air inlet pipes. The dust removal cylinder device includes a cylinder body, output covers installed at both ends of the cylinder body, and a filter element assembly installed in the cylinder body. The filter element assembly includes a support sleeve installed on the output cover, a mesh cover fixedly installed on the support sleeve, and a filter screen inserted in the mesh cover. The mesh cover has a clamping groove, the output cover has a clearance groove, and the mesh cover also has an installation groove. The installation groove communicates with the clamping groove, and the filter screen is inserted into the clamping groove and the clearance groove through the installation groove.

[0005] Furthermore, the mesh cover is provided with a clamping protrusion extending axially along the support sleeve, and the clamping groove is formed on the end face of the clamping protrusion.

[0006] Furthermore, a clamping screw is provided on the outer side of the clamping protrusion, and the end of the clamping screw is pressed into the filter screen after being tightened.

[0007] Furthermore, the mounting groove is formed on one side of the clamping screw, and the clamping screw fixes the mesh cover and the filter screen.

[0008] Furthermore, a support platform is provided at the middle position of the output cover, the end of the support sleeve is fixed on the support platform, and the clearance groove is formed on the support platform.

[0009] Furthermore, the sides of the support platform have a sloping structure.

[0010] Furthermore, the dust removal cylinder device also includes an input cover installed at the end of the cylinder body, and the input cover and the output cover are respectively located on both sides of the cylinder body.

[0011] Furthermore, both the input cover and the output cover are connected to the air inlet pipe.

[0012] The beneficial effects of this invention are that when the filter needs cleaning, simply remove the output cover from the cylinder. The output cover, along with the support sleeve and filter, is then removed from the cylinder. After the filter is removed from the clamping groove and the clearance groove, a new filter is installed from the mounting groove into the clamping groove and the clearance groove. This allows the old filter to be laid flat before cleaning, effectively preventing scratches and deformation. It also improves the efficiency of filter replacement, ensuring effective dust removal in the laboratory. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 5 As shown, this embodiment provides a laboratory computer room dust removal system, including an axial flow fan 10, an inlet pipe 20 and an outlet pipe 30 mounted on both sides of the axial flow fan 10, a dust collection cylinder device 40 mounted on the inlet pipe 20, and air inlets and outlets 50 disposed within the laboratory. After the axial flow fan 10 is started, it promotes the circulation of gas within the laboratory through the inlet pipe 20 and the outlet pipe 30. During the gas flow process, the gas passes through the dust collection cylinder device 40, and after being filtered for dust by the dust collection cylinder device 40, it enters the laboratory through the air inlets and outlets 50.

[0022] like Figure 1 As shown, the axial flow fan 10 is installed between the air inlet pipe 20 and the air outlet pipe 30, and the dust collector 40 is installed on the air inlet pipe 20. The ends of the air inlet pipe 20 and the air outlet pipe 30 are connected to the air inlet and outlet 50. The air inlet and outlet 50 are located on the wall of the laboratory. When the axial flow fan 10 is started, a circulating airflow is generated in the air inlet pipe 20 and the air outlet pipe 30. The air in the laboratory flows out from the air inlet and outlet 50 to the air outlet pipe 30. Driven by the axial flow fan 10, the air enters the air inlet pipe 20. After being cleaned by the dust collector 40, the airflow returns to the laboratory through the air inlet pipe 20 and the air inlet and outlet 50.

[0023] like Figure 2 , Figure 4 as well as Figure 5 As shown, the dust collection cylinder device 40 includes a cylinder 410, an input cover 420 and an output cover 430 installed at both ends of the cylinder 410, and a filter element assembly 440 installed in the cylinder 410.

[0024] The cylinder 410 has a cylindrical cavity structure. An inlet cover 420 and an outlet cover 430 are respectively installed on both ends of the cylinder 410. Both the inlet cover 420 and the outlet cover 430 are connected to the air inlet pipe 20. Airflow in the air inlet pipe 20 enters the cylinder 410 through the inlet cover 420. After dust is filtered in the cylinder 410, the gas is discharged back into the air inlet pipe 20 through the outlet cover 430. The filter element assembly 440 includes a support sleeve 441 mounted on the outlet cover 430, a mesh cover 442 fixed on the support sleeve 441, and a filter screen 443 inserted into the mesh cover 442.

[0025] like Figures 2 to 5 As shown, the end of the support sleeve 441 is fixed to the output cover 430. A mesh 444 is opened on the side wall of the support sleeve 441. The support sleeve 441 and the output cover 430 are connected. The mesh cover 442 is rotatably and sealingly fitted onto the other end of the support sleeve 441. A clamping protrusion 445 is provided on the mesh cover 442 extending axially along the support sleeve 441. A clamping screw 446 is inserted through the outer side of the clamping protrusion 445. A circumferential opening is provided on the end face of the clamping protrusion 445. The clamping groove 447 has its end inserted into it. A mounting groove 448 is formed on the outer wall of the clamping protrusion 445, connecting to the clamping groove 447. The mounting groove 448 is located on one side of the clamping screw 446. The side of the filter screen 443 passes through the mounting groove 448 into the clamping groove 447. After the clamping screw 446 is tightened, its end presses against the groove wall of the clamping groove 447, thus securing the mesh cover 442 and the filter screen 443 together. The filter screen 443, constrained by the clamping groove 447, covers the support sleeve 441. After entering the cylinder 410, the gas is filtered by the filter screen 443 and then enters the mesh 444. The filter screen 443 filters dust from the air, and the filtered air is discharged through the output cover 430.

[0026] Preferably, a support platform 431 is provided in the middle of the output cover 430, the end of the support sleeve 441 is fixed on the support platform 431, and an exhaust port 432 is opened in the middle of the support platform 431, which is connected to the support sleeve 441 and the air inlet pipe 20.

[0027] Preferably, the support platform 431 has a clearance groove 433, which corresponds to the clamping groove 447. One side of the filter screen 443 is inserted into the clamping groove 447, and the other side of the filter screen 443 is inserted into the clearance groove 433. The two sides of the filter screen 443 are clamped and fixed by the clamping groove 447 and the clearance groove 433, respectively.

[0028] Preferably, the side of the support platform 431 of the output cover 430 has a sloping structure. After the dust on the filter screen 443 falls onto the support platform 431, it slides down the slope and accumulates between the support platform 431 and the cylinder 410.

[0029] When the above-mentioned laboratory computer room dust removal system is in use, after the axial flow fan 10 is started, the air in the computer room is introduced into the air inlet pipe 20 and the air outlet pipe 30. When the air passes through the air inlet pipe 20, the air enters the cylinder 410 through the inlet cover 420. After being filtered by the filter screen 443 inside the cylinder 410, it enters the support sleeve 441. After passing through the support sleeve 441, the dust removal air flows out from the outlet cover 430 into the air outlet pipe 30, and finally flows back into the laboratory computer room through the air inlet and outlet 50. After a long period of dust removal, loosen the output cover 430 from the cylinder 410 in the dust collector device 40. The output cover 430, carrying the filter element assembly 440, is taken out from the cylinder 410. When replacing the filter screen 443, first loosen the clamping screw 446, remove the old filter screen 443 from the clamping groove 447 and the clearance groove 433, and then insert the new filter screen 443 along the mounting groove 448 into the clamping groove 447 and the clearance groove 433. The filter element assembly 440 with the new filter screen 443 is then reassembled into the cylinder 410.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
