Description

Technical Field

[0001] This utility model relates to the technical field of air compressor systems for cell laboratories and their purification and filtration devices, and in particular to an air compressor system for cell laboratories and its purification and filtration device. Background Technology

[0002] In cell biology laboratories, experiments require specific values ​​for ambient air pressure, quality, and cleanliness. Therefore, cell biology laboratories are often equipped with compressed air systems to replace the air and ensure its freshness. For example, patent number CN202121635152.0 discloses a positive / negative pressure laboratory conversion device, which includes a pipeline with a purification unit. Both the fresh air duct and return air duct in the pipeline connect to the interior of the laboratory, regulating the air pressure and cleanliness during the circulation process. When this equipment is applied to a cell biology laboratory, if the device stops intake and adjusts to a negative pressure or sealed environment, the experimenter needs to close the air inlet. Existing technologies mostly use electrically controlled valves or ball valves to control the intake process. Because these valves are often large and installed outside the laboratory, operators need to go outside to adjust them, significantly impacting the laboratory's adjustment efficiency. Utility Model Content

[0003] The technical problem this invention aims to solve is that the valve control process in laboratory air compressor systems is too cumbersome, affecting the efficiency of laboratory regulation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a purification and filtration device, including a filter box, a control sleeve installed at the air outlet of the filter box, a control plate fixed on the inner wall of the control sleeve, and a control component installed in the middle of the control plate. The filter box purifies and filters the input air. The control plate and the inner wall of the control sleeve are sealed together. The control plate has a vent hole. The control component includes a drive plate installed between the control plate and the filter box, a plug installed on the drive plate, and a control column installed on the drive plate. The plug can be inserted to block the vent hole. One end of the control column is fixed on the drive plate, and the other end of the control column extends out of the control sleeve. The control column can slide through the control plate.

[0005] Furthermore, the control component also includes a spring installed between the drive plate and the control plate, with both ends of the spring fixed to the drive plate and the control plate respectively.

[0006] Furthermore, the control component also includes a push plate mounted on the end of the control column, a pin mounted on the push plate, and a rotating ring corresponding to the pin. A chuck is mounted on the end of the pin, and the rotating ring is rotatably mounted on the control sleeve. The pin and the chuck can be inserted into the surface of the rotating ring.

[0007] Furthermore, a clearance hole is formed on the surface of the rotating ring facing the pin, and a control groove is formed below the clearance hole. The chuck can pass through the clearance hole and be inserted into the control groove.

[0008] Furthermore, the control panel has a sliding hole, the vent is arranged around the sliding hole, and the control post can slide through the sliding hole.

[0009] Furthermore, a cell laboratory compressed air system includes a purification and filtration device as described in any of the preceding claims.

[0010] Furthermore, it also includes an inlet / outlet device and a pipeline device connecting the inlet / outlet device and the purification and filtration device. The inlet / outlet device includes an air inlet and an air outlet, and the filter box is installed on the air inlet.

[0011] Furthermore, the piping system includes a return air pipe connected to the air inlet, an air outlet pipe connected to the air outlet, and an air inlet pipe connected to the return air pipe.

[0012] Furthermore, a circulating fan is installed on the return air duct, an outlet air fan is installed on the outlet air duct, and a fresh air valve is installed on the inlet air duct.

[0013] The beneficial effect of this utility model is that the control column is driven to slide relative to the control plate outside the control sleeve, thereby controlling the plug to block the vent hole or pull it out from the vent hole, thereby controlling the opening and closing of the air inlet of the laboratory. Since the filter and purification device is small in size and located at the air inlet, the control column and control sleeve are located in the laboratory room, and the operator can easily adjust it according to the needs.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 5 As shown, this embodiment provides a cell laboratory air compressor system 100, including an inlet / outlet device 10 installed on the inner wall of the laboratory, a purification and filtration device 20, and a pipeline device 30 connecting the inlet / outlet device 10 and the purification and filtration device 20 and extending to the outside of the laboratory. Gas inside the laboratory is discharged through the inlet / outlet device 10 and the pipeline device 30, while fresh outside air is introduced. After the fresh air passes through the purification and filtration device 20 and reaches the required air cleanliness level, it is discharged into the room through the inlet / outlet device 10.

[0023] like Figure 1 As shown, the inlet and outlet device 10 includes an air inlet 110 and an air outlet 120 installed on the laboratory wall. The purification and filtration device 20 is installed on the air inlet 110. Fresh air can be introduced into the laboratory through the air inlet 110 and the air in the laboratory can be discharged through the air outlet 120, thereby promoting the air circulation in the laboratory.

[0024] like Figure 1 and Figure 2As shown, the purification and filtration device 20 includes a filter box 210 installed on the air inlet 110, a control sleeve 220 installed at the air outlet of the filter box 210, a control plate 230 fixed on the inner wall of the control sleeve 220, and a control component 240 installed in the middle of the control plate 230.

[0025] The filter box 210 purifies and filters the air input through the air inlet 110. Specifically, the filter box 210 can hold purification supplies such as activated carbon and dust-absorbing cotton. The air input through the air inlet 110 is treated to the required level of cleanliness within the filter box 210, and then input into the laboratory through the control sleeve 220. The control plate 230 is mounted parallel to the control sleeve 220, and the inner wall of the control plate 230 and the control sleeve 220 are sealed together. The control plate 230 has a sliding hole 231, and several ventilation holes 232 are arranged around the sliding hole 231, which connect to the spaces on both sides of the control plate 230.

[0026] like Figures 3 to 5 As shown, the control unit 240 includes a drive plate 241 installed between the filter box 210 and the control plate 230, a plug 242 installed on the drive plate 241, a control column 243 fixed in the middle position of the drive plate 241, a spring 244 sleeved on the control column 243, and a push plate 245 installed at the end of the control column 243.

[0027] The area of ​​the drive plate 241 is smaller than the inner cavity area of ​​the control sleeve 220, that is, there is a gap between the inner wall of the drive plate 241 and the control sleeve 220. There are multiple plugs 242, and the plugs 242 are correspondingly arranged with the vent holes 232. When the drive plate 241 moves toward the control plate 230, the plugs 242 can block the vent holes 232, cutting off the connection between the cavities on both sides of the control plate 230. The control column 243 can slide through the sliding hole 231 of the control plate 230. One end of the control column 243 is fixedly connected to the drive plate 241, and the other end extends to the outside of the control sleeve 220. Through the control column 243, the drive plate 241 can be driven to move closer to or away from the control plate 230 from the outside of the control sleeve 220, thereby driving the plugs 242 to block the vent holes 232 or pull them out from the vent holes 232. The two ends of the spring 244 are fixed to the drive plate 241 and the control plate 230, respectively. Under the action of the spring 244, the drive plate 241 maintains a tendency to move away from the drive plate 230. The push plate 245 and the drive plate 241 are respectively located at the two ends of the control column 243. The push plate 245 is fixed to the control column 243, and the operator can drive the control column 243 to move through the push plate 245.

[0028] Preferably, the control component 240 further includes a pin 246 mounted on the push plate 245 and a rotating ring 247 corresponding to the pin 246. One end of the pin 246 is fixed to the push plate 245, and a chuck 248 is fixedly mounted on the other end of the pin 246. The rotating ring 247 is rotatably mounted on the control sleeve 220. The pin 246 and the chuck 248 can be inserted into the surface of the rotating ring 247. A clearance hole 2471 is opened on the surface of the rotating ring 247 facing the pin 246. A control groove 2472 is provided below the clearance hole 2471. The diameter of the clearance hole 2471 is larger than the diameter of the chuck 248. The cross-section of the control groove 2472 is T-shaped. The chuck 248 can be inserted into the clearance hole 2471. After the chuck 248 is inserted, the rotating ring 247 is rotated. Through the clearance of the control groove 2472, the chuck 248 rotates relative to the pin 246. Under the limit of the control groove 2472, the pin 246 and the chuck 248 are fixed in the rotating ring 247. When the plunger 242 is inserted into the vent hole 232, the control sleeve 220 can be blocked, thereby blocking the air inlet 110 in the laboratory. Rotating the rotating ring 247 in the opposite direction again allows the chuck 248 to disengage from the clearance hole 2471. Under the action of the spring 244, the plunger 242 in the vent hole 232 is pulled out, and the cavities on both sides of the control plate 230 are connected.

[0029] The ductwork device 30 includes a return air duct 310 connected to the air inlet 110, an air outlet duct 320 connected to the air outlet 120, and an air inlet duct 330 connected to the return air duct 310. The other end of the return air duct 310 is also connected to another air outlet 120 of the laboratory. A circulating fan 340 is installed on the return air duct 310. After the circulating fan 340 is started, the air in the laboratory circulates in the return air duct 310. An air outlet fan 350 is installed on the air outlet duct 320. After the air outlet fan 350 is turned on, the air in the laboratory can be discharged from the air outlet duct 320. A fresh air valve 360 ​​is installed on the air inlet duct 330. After the fresh air valve 360 ​​is turned on, fresh air from the outside can enter the return air duct 310 from the fresh air duct 330 and be discharged into the laboratory through the air inlet 110.

[0030] When the aforementioned cell laboratory air compressor system 100 is in use, the ductwork 30 and the purification filter 20 are adjusted according to the laboratory's air requirements. When a negative pressure state is required, the purification filter 20 is closed, and the exhaust fan 350 is turned on to exhaust the air in the laboratory until the negative pressure standard is reached. When a sealed circulation air mode is required, the exhaust fan 350 and the fresh air valve 360 ​​are closed, the purification filter 20 is turned on, and the circulation fan 340 is turned on. The air in the laboratory can circulate in the return air duct 310. When the indoor air needs to be refreshed, the fresh air valve 360, the purification filter 20, the circulation fan 340, and the fresh air valve 360 ​​are opened. When the air in the laboratory is exhausted, outdoor fresh air enters the laboratory after passing through the filter box 210.

[0031] 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.
