Description

Technical Field

[0001] This invention relates to the field of air purification and ventilation device technology, specifically to a high-throughput air purification and ventilation device for laboratories and its usage method. Background Technology

[0002] Laboratory environments generally have high requirements. Providing a stable environment for researchers is crucial for the accuracy of experimental data. However, the air in the laboratory inevitably exchanges with the outside air. In addition to providing the oxygen needed by the people in the laboratory, the outside air also brings bacteria and dust from the outside air into the laboratory. Moreover, the air exchange capacity required by the laboratory is relatively large. Therefore, high-throughput air purification and ventilation devices are often used in laboratories.

[0003] However, in the existing high-throughput air purification and ventilation devices, the filter components are usually disassembled and cleaned during the air filtration process. This makes it inconvenient to automatically replace and clean the filter components, which affects the cleaning capacity, filtration effect, and filtration efficiency of the device. Therefore, based on the shortcomings of the technology, a laboratory air purification and ventilation device and its usage method are proposed to solve the above problems. Summary of the Invention

[0015] The beneficial effects of this invention are: The rotating plate and the filter tank on the second gear in the cleaning assembly perform multi-stage filtration of air, and facilitate the intermittent transmission and replacement of the filter tank. It also facilitates the cleaning operation of the replaced filter tank, which is beneficial to improving the cleaning capacity of the device, the filtration effect of the device, the ability to replace the filter tank, and the working efficiency of the device's filtration and purification. The heating rod in the drying assembly, together with the absorbent cotton, facilitates the heating and drying of the filter tank. After drying, the filter tank enters the air supply pipe for filtration, which helps to improve the heating and drying capacity of the device and improve the filtration efficiency of the device. The rotating rod in the swing assembly facilitates the rotation of the rotating shaft, and the swing blades are driven to swing within the mounting frame by the pull rope under the action of the spring. This makes it easy to change the direction of the airflow from the air supply duct into the laboratory, and facilitates flexible swing operation. This improves the flexibility and applicability of the device, enhances the device's ability to change the airflow direction, and improves the user experience of the device.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 12 As shown, the present invention is a laboratory high-throughput air purification and ventilation device, including a housing 1. A blower 3 is fixedly installed at the bottom of the housing 1. The blower 3 facilitates drawing external air into the air supply pipe 2, which is then filtered and purified before being blown into the laboratory. The top of the blower 3 is connected to the air supply pipe 2. The vertical cross-section of the air supply pipe 2 is inverted L-shaped. A fixing plate 7 is fixedly installed between the top of the housing 1 and the air supply pipe 2. There are multiple fixing plates 7, which are used to fix the air supply pipe 2. A cleaning assembly 4 is provided inside the housing 1. The cleaning assembly 4 includes a second gear 45 and a rotating plate 46 that are slidably mounted on the air supply duct 2. Both the second gear 45 and the rotating plate 46 are provided with filter grooves 47. The diameter of the filter holes in the filter groove 47 on the second gear 45 is larger than the diameter of the filter holes in the filter groove 47 on the rotating plate 46. The second gear 45, together with the rotating plate 46, performs multi-stage filtration and purification of the air in the air supply duct 2. In addition, the filter grooves 47 facilitate the transport of filtered dust and impurities out of the air supply duct 2 for processing. A first motor 43 is fixedly mounted on the side of the fixed plate 7 near the blower 3. A rotating shaft with a first gear 42 is rotatably mounted between the fixed plate 7 and the inner wall of the housing 1. 44. The first gear 42 is fixedly mounted on the rotating shaft 44. The first gear 42 and the second gear 45 mesh with each other. An mounting plate 410 is fixedly mounted on the inner wall of one side of the housing 1. The mounting plate 410 serves to mount and fix the cleaning plate 48. Two cleaning plates 48 are fixedly mounted on both sides of the rotating plate 46 and the second gear 45. The two cleaning plates 48 serve to clean the front and back sides of the rotating plate 46 and the second gear 45 simultaneously. Spray nozzles 49 are connected and installed on the corresponding sides of the two cleaning plates 48. An extension plate 414 is fixedly mounted on the bottom of one cleaning plate 48, and a cleaning brush 418 is fixedly mounted on the bottom of the other cleaning plate 48. The brush 418 facilitates cleaning of the filter tank 47 when the rotating plate 46 or the second gear 45 rotates. An electric telescopic rod 416 is fixedly installed on the side of the extension plate 414 closest to the filter tank 47. The electric telescopic rod 416 facilitates the extension of the cleaning disc 417 into the filter tank 47. The cleaning disc 417 is fixedly installed on the side of the electric telescopic rod 416 away from the extension plate 414. A second motor 415 is fixedly installed on the side of the extension plate 414 away from the electric telescopic rod 416. The output end of the second motor 415 slides through the extension plate 414 and is fixedly installed on the electric telescopic rod 416. The cleaning disc 417 is engaged within the filter tank 47. The machine 415 drives the electric telescopic rod 416 and the cleaning disc 417 to rotate and clean in the filter tank 47, and is equipped with a nozzle 49 to rinse the filter tank 47. A water tank 41 is fixedly installed on the inner bottom wall of the housing 1. A water receiving tank 412 and a water pump 413 are fixedly installed on the top of the water tank 41. The water receiving tank 412 serves to receive the sewage after rinsing. A water pipe 411 is connected to the top of the water pump 413. The other end of the water pipe 411 is connected to the mounting plate 410. The mounting plate 410 and the cleaning plate 48 are connected to each other to facilitate the transportation of water in the water pipe 411 to the nozzle 49. An intermittent transmission unit is provided between the second gear 45 and the rotating plate 46.

[0021] The intermittent transmission unit includes a gear groove 419 formed on the rotating plate 46 near the second gear 45. A fixed disk 424 is rotatably mounted on the inner wall of the gear groove 419. A ring of teeth 421 is fixedly installed on the inner wall of the gear groove 419, for example, 20 teeth 421. The idler gear 420 has 10 teeth, and the half gear 422 has 5 teeth. Since the half gear 422 is connected by a connecting rod 423, the half gear 422 and the second gear 45 move synchronously. Therefore, when the second gear 45 rotates four times, the connecting rod 423 drives the half gear 422 to rotate four times. The four rotations of the half gear 422 drive the idler gear 420 to rotate two times. The idler wheel 420 drives the rotating plate 46 to rotate one revolution. Therefore, it can be concluded that the filter tank 47 is replaced four times when the second gear 45 rotates one revolution. Due to the drive of the intermittent transmission unit, the rotating plate 46 rotates one-quarter revolution on the air supply pipe 2, that is, the filter tank 47 is replaced once. A connecting rod 423 is fixedly installed on the side of the second gear 45 near the rotating plate 46. A half gear 422 is fixedly installed on the side of the connecting rod 423 near the gear groove 419. The idler wheel 420 is rotatably installed on the side of the fixed disk 424 near the half gear 422. The end of the half gear 422 away from the connecting rod 423 is rotatably installed on the fixed disk 424. The connecting rod 423 is located on the half gear 422. The rotating plate 46 rotates and connects to the fixed plate 424, facilitating stable installation of the second gear 45. The rotating shaft of the fixed plate 424 slides through the gear groove 419 and is fixedly mounted on the connecting rod 423 on the side of the rotating plate 46 away from the half gear 422, allowing the rotating plate 46 to rotate on the fixed plate 424. The idler gear 420 is installed between the half gear 422 and the tooth 421, with the half gear 422 and the idler gear 420 meshing with each other, and the idler gear 422 and the tooth 421 meshing with each other. The output end of the first motor 43 slides through the fixed plate 7 and is fixedly mounted on the rotating shaft 44, where the first gear 42 and the second gear 45 mesh with each other. The end of the connecting rod 423 on the second gear 45 away from the rotating plate 46 rotates. The rotating plate 46 is mounted on the air supply duct 2. The end of the connecting rod 423 on the rotating plate 46 away from the second gear 45 is fixedly mounted on the inner wall of the housing 1. This serves to stabilize the rotating plate 46, facilitate multi-stage filtration of air through the filter grooves 47 on the rotating plate 46 and the second gear 45, and facilitate intermittent transmission replacement of the filter grooves 47, minimizing the need for manual replacement and cleaning. It also facilitates cleaning of the replaced filter grooves 47, which is convenient for cleaning operations, improves the cleaning capacity of the device, improves the filtration effect of the device, improves the ability to replace the filter grooves 47, and improves the working efficiency of the device's filtration and purification.

[0022] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9As shown, a drying assembly 5 is provided on the cleaning plate 48. The drying assembly 5 includes an arc-shaped plate 51 fixedly installed on the top surface of the cleaning plate 48. The curvature of the arc-shaped plate 51 matches the curvature of the rotating plate 46 and the second gear 45, facilitating the drying operation of the rotating plate 46 and the second gear 45. A groove 52 is formed on the side of the two arc-shaped plates 51 that is close to each other. A heating rod 53 is fixedly installed in the groove 52. The heating rod 53 is controlled by the temperature controller 55 to heat and dry the filter tank 47. A water-absorbing cotton 54 is fixedly installed on the arc-shaped plate 51 near the cleaning plate 48. 54 is fixedly installed on the corresponding side of the two arc-shaped plates 51. The absorbent cotton 54 is convenient for absorbing excess water from the rotating plate 46 and the second gear 45, and for the heating rod 53 to dry the rotating plate 46 and the second gear 45. A temperature controller 55 is fixedly installed on the side of the housing 1 away from the first motor 43. The temperature controller 55 and the heating rod 53 are electrically connected, which facilitates heating and drying of the filter tank 47. After drying, the filter tank 47 enters the air supply pipe 2 for filtration, which helps to improve the heating and drying capacity of the device and improve the filtration efficiency of the device.

[0023] Please see Figure 1 , Figure 2 and Figure 4As shown, a swing assembly 6 is provided on the housing 1. The swing assembly 6 includes a mounting frame 61 fixedly installed on the side of the housing 1 near the temperature controller 55. The air supply duct 2 and the mounting frame 61 are interconnected. The mounting frame 61 facilitates the blowing of filtered and purified air from the air supply duct 2 into the laboratory. Multiple swing blades 62 are rotatably installed inside the mounting frame 61. Connecting ropes 63 are fixedly installed between the multiple swing blades 62. The connecting ropes 63 facilitate the synchronous movement of the multiple swing blades 62. During the swinging process, the swing blades 62 can easily change the air direction blown into the laboratory from the air supply duct 2. A spring 64 is fixedly installed on the top wall of the mounting frame 61. A rotating groove 66 is opened on the side of the housing 1 near the mounting frame 61. A rotating rod 67 is rotatably installed in the rotating groove 66. A pull rope 65 is fixedly installed at one end of the rotating rod 67. The rotating rod 67 drives the pull rope 65 to pull the swing blades 62 to swing within the mounting frame 61. The device is designed to be flexible and adaptable. A protective plate 68 is installed at an angle between the housing 1 and the mounting frame 61. The protective plate 68 protects the pull rope 65 and the rotating rod 67. The rotating shaft of the rotating rod 67 slides through the housing 1 and is fixedly mounted on the rotating shaft 44. The end of the pull rope 65 away from the rotating rod 67 slides through the mounting frame 61 and is fixedly mounted on the swing blade 62. The end of the spring 64 away from the mounting frame 61 is fixedly mounted on the swing blade 62. The spring 64 serves to elastically reset the swing blade 62, allowing the rotating rod 67 to swing within the mounting frame 61 by rotating the rotating shaft 44 and pulling the pull rope 65 under the action of the spring 64. This facilitates changing the direction of the airflow from the air supply pipe 2 into the laboratory, enabling flexible and adaptable swinging operation, improving the device's flexibility and adaptability, enhancing its ability to change airflow direction, and improving the user experience.

[0024] A method of using a high-throughput air purification and supply device for laboratories, applicable to the aforementioned high-throughput air purification and supply device for laboratories, includes the following steps: Step 1: The device draws outside air into the air supply pipe 2 through the blower 3, filters it through the filter tank 47 for multiple stages, and then blows it into the laboratory through the mounting frame 61. Step 2: When cleaning the filter tank 47, first start the first motor 43, so that the first motor 43 drives the first gear 42 to rotate through the rotating shaft 44, so that the first gear 42 meshes and drives the second gear 45 to rotate in the air supply pipe 2, so that the second gear 45 replaces the new filter tank 47 for filtration. At the same time, the rotating plate 46 is intermittently driven by the half gear 422 on the connecting rod 423 to rotate in the air supply pipe 2 to update the new filter tank 47 for filtration and air purification. Step 3: Then start the water pump 413 to transport the water in the water tank 41 to the cleaning plate 48 through the water pipe 411, and spray it into the rotating plate 46 through the nozzle 49. When the filter tank 47 that needs to be cleaned moves to the cleaning disc 417, then start the electric telescopic rod 416 to make the cleaning disc 417 clean the nozzle 49 under the drive of the second motor 415. Step 4: After tilting the filter tank 47, it is dried by the absorbent cotton 54 and the heating rod 53. At the same time, as the rotating shaft 44 rotates, the rotating rod 67 drives the swing blade 62 to swing up and down in the mounting frame 61 through the pull rope 65, so as to change the direction of the air blown into the laboratory by the air supply pipe 2.

[0025] The working principle of the present invention: When using the device, first start the blower 3, so that the blower 3 draws the external air into the air supply pipe 2, and the air in the air supply pipe 2 passes through the filter groove 47 on the second gear 45 and the filter groove 47 on the rotating plate 46 for step-by-step filtration and purification. The filtered and purified air is blown into the laboratory through the mounting frame 61. When a certain amount of dust accumulates on one of the filter slots 47 on the rotating plate 46, the first motor 43 is started, causing the output end of the first motor 43 to drive the rotating shaft 44 to rotate. The rotating shaft 44 drives the first gear 42 to rotate, causing the first gear 42 to mesh and drive the second gear 45 to rotate on the air supply pipe 2. The second gear 45, through the half gear 422 on the connecting rod 423, drives the idler gear 420 to rotate, causing the idler gear 420 to mesh and drive the rotating plate 46 to rotate on the fixed plate 424. The rotating plate 46 rotates on the air supply pipe 2, and the second gear 45 rotates one revolution on the air supply pipe 2. After the filter tank 47 is replaced four times, the rotating plate 46 rotates one-quarter revolution on the air supply pipe 2 and completes one replacement of the filter tank 47. At the same time, the water pump 413 is started, which pumps the clean water in the water tank 41 into the water pipe 411 and transports it into the mounting plate 410 and the cleaning plate 48. The clean water is then sprayed onto the filter tank 47 through the nozzle 49 for cleaning. When the filter tank 47 moves to the cleaning disc 417, the electric telescopic rod 416 is first activated, causing it to drive the cleaning disc 417 into the filter tank 47. Then, the second motor 415 is activated, causing its output to rotate the electric telescopic rod 416 and the cleaning disc 417 within the filter tank 47 to clean the dust. The electric telescopic rod 416 is then retracted to pull the cleaning disc 417 out of the filter tank 47. Simultaneously, the rotating plate 46 and the second gear 45, under the action of the cleaning brush 418, perform a synchronized cleaning operation on the back of the filter tank 47 during rotation. After cleaning, the filter tank 47 is rinsed again by the spray nozzle 49 during rotation. Then, the temperature controller 55 is activated, causing the heating rod 53 to heat the filter tank 47, while simultaneously... After the filter tank 47 absorbs water through the absorbent cotton 54, it is dried by the heating rod 53, allowing the cleaned wastewater to flow into the water receiving tank 412. At the same time, the rotating shaft 44 rotates, driving the rotating rod 67 to rotate in the rotating groove 66. When the rotating rod 67 drives the pull rope 65 to its highest point, the pull rope 65 pulls the swing blade 62 to rotate upward in the mounting frame 61. Multiple swing blades 62 move synchronously under the drive of the connecting rope 63, and at the same time, the swing blades 62 compress the spring 64, keeping the spring 64 in a compressed state. Then, as the rotating rod 67 continues to rotate, it drives the pull rope 65 to its lowest point, and the elastic restoring force of the spring 64 drives the swing blade 62 to rotate downward in the mounting frame 61. At the same time, the pull rope 65 slides in the mounting frame 61, which facilitates changing the direction of the airflow from the air supply duct 2 into the laboratory.
