Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and more specifically to air purification equipment with sealing detection performance used in pharmaceutical workshops. Background Art

[0002] Air purification equipment is a product that can filter out or kill air pollutants and effectively improve air cleanliness. It is mainly used for household and commercial air purification equipment to remove indoor air pollution. Air purification equipment can filter out pollutants such as airborne particulate matter, bacteria, viruses, fungal spores, pollen, asbestos, and radon decay products.

[0003] When the existing air purification equipment with detection sealing performance is used in pharmaceutical workshops, the filter screen is fixedly installed. After the entire filter screen is used for a long time, the filter port of the filter screen is gradually blocked, causing the entire air flow rate to gradually decrease. In addition, after the existing purification equipment is used for a long time, it is inconvenient to disassemble and clean the filter screen.

[0004] For example, patent application number CN202122467721.1 discloses an air purification device for pharmaceutical workshops with sealing performance detection, including a base, a filter box, an air tightness detector, an air inlet pipe, a sleeve, a first plug-in board, an arc plate, an adsorption cotton block, a bonding plate, a first support plate, a fan, a first connecting column, a baffle, an air outlet pipe, a second connecting column, a limit nut, a first connecting plate, a HEPA filter, a top plate, a fixed plate, a second connecting plate, an activated carbon filter, a second plug-in board, a second support plate, a fan blade, a soft brush and a processing box. Through the setting of the cleaning mechanism, when the entire purification device is in use, the air flow inside the air outlet pipe begins to flow, and the flowing air flow flows out through the air outlet of the air outlet pipe, thereby causing the fan blade to start rotating, and the rotating fan blade drives the soft brush to clean the surface of the activated carbon filter, thereby avoiding the filter port of the activated carbon filter from being blocked, thereby facilitating the maintenance of the air pass rate.

[0005] In this structure, the airflow in the pharmaceutical workshop is purified by setting a filter plate and a filter net, and the filter plate is cleaned by fan blades and a soft brush. In this structure, the soft brush only cleans the sides of the fixed position of the filter plate, resulting in a poor cleaning effect. At the same time, the disassembly and cleaning of the internal components in this structure requires shutdown processing. The large number of operating steps also affects the purification efficiency of the equipment. Therefore, professionals in this field provide an air purification equipment for a pharmaceutical workshop to solve the above-mentioned problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4In the utility model, an air purification device with sealing performance detection for a pharmaceutical workshop comprises a filter box 1 and an air tightness detector 2 installed on the front thereof, an air intake pipe 3 and an exhaust pipe 4 which are both connected to the interior of the filter box 1 are fixedly connected on the left and right sides thereof, a fan 5 is installed on the inner wall of the air intake pipe 3, a filter plate 6 is installed on the inner wall of the filter box 1, a servo motor 7 is fixedly installed on the front of the filter box 1, an output shaft of the servo motor 7 passes through and extends to the interior of the filter box 1, a screw rod is fixedly connected to the output shaft of the servo motor 7, a bearing seat 8 is threadedly connected to the screw rod, a cleaning roller 9 is rotatably connected to the bottom of the bearing seat 8, the cleaning roller 9 is located on the left side of the filter plate 6, and the inner wall of the filter box 1 A rack 10 is fixedly connected to the top, a gear ring 11 is installed on the cleaning roller 9, the gear ring 11 is meshed with the rack 10, through grooves 12 are provided on the front and back of the filter box 1, a guide seat 13 is fixedly connected to the inner wall of the filter box 1, two sealing splints 14 are slidably connected to the inner wall of the guide seat 13, and evenly distributed springs 15 are fixedly connected to the sealing splints 14, and the other end of the spring 15 is fixedly connected to the inner wall of the guide seat 13, and a driving assembly 16 is arranged inside the guide seat 13, and a HEPA filter 17 is arranged inside the filter box 1, and the top and bottom of the HEPA filter 17 are respectively located inside the two guide seats 13, and the sealing splint 14 is in contact with the HEPA filter 17.

[0024] The driving assembly 16 includes two metal plates 1601 , which are fixedly connected to the sealing clamping plate 14 . Two electromagnetic seats 1602 are installed on the inner wall of the guide seat 13 , and the electromagnetic seats 1602 are magnetically connected to the metal plates 1601 .

[0025] A collecting box 21 is inserted into the left side of the filter box 1 , and the collecting box 21 is slidably connected to the inner wall of the filter box 1 .

[0026] When the purification equipment is in use, it is moved to the pharmaceutical workshop through the bottom pulley. The air tightness detector 2 can detect the air tightness of the equipment, and then the fan 5 is controlled to operate. The fan 5 generates suction to send the air flow inside the pharmaceutical workshop into the filter box 1 through the air inlet pipe 3. Then the air flow moves to the right and penetrates the filter plate 6, and the dust in the air flow will adhere to the filter plate 6 or be blocked by the filter plate 6. The dust goes down into the collection box 21 and is collected. Then the air flow continues to move to the right. It is restricted by the two sets of guide seats 13 so that the air flow passes through the middle HEPA filter 17 and is discharged from the exhaust pipe 4. The exhaust air flow will be purified and enter the pharmaceutical workshop. After operating for a period of time, the user can control the servo motor 7 to power on. After the servo motor 7 is powered on, it drives the screw rod fixed to it to rotate synchronously. The bearing seat 8 threadedly connected to the screw rod begins to slide inside the filter box 1. At this time, the cleaning roller 9 and the gear ring 11 move accordingly. Since the gear ring 11 is engaged with the rack 10, the gear ring 11 rolls on the rack 10, and the cleaning roller 9 and the gear ring 11 move accordingly. The drum 9 rotates accordingly, so that the dust attached to the filter plate 6 is cleaned and enters the collection box 21 under the action of gravity. The collection box 21 can be pulled out for processing. When the HEPA filter 17 needs to be replaced, the user controls the electromagnetic seat 1602 to be energized, and the electromagnetic seat 1602 generates magnetism to attract the metal plate 1601, so that the multiple groups of springs 15 are forced to shrink and pull the sealing splint 14 to separate from the HEPA filter 17. Then the user sends the prepared unused HEPA filter 17 into the front groove 12, and the used HEPA filter 17 begins to be discharged from the back groove 12. As the HEPA filter 17 pushes, the unused HEPA filter 17 is completely fitted with the guide seat 13, and the HEPA filter 17 on the back is pushed out. During this process, the purification equipment can operate continuously. Then the user controls the electromagnetic seat 1602 to be powered off, and the spring 15 pushes the sealing splint 14 to reset, so that the HEPA filter 17 can be limited and the quick replacement is completed.

[0027] In the utility model, the air in the pharmaceutical workshop is purified by the cooperation between the filter plate 6 and the HEPA filter 17. At the same time, the filter plate 6 is cleaned by the self-rotating cleaning roller 9, so that clogging can be avoided and the machine can be started for cleaning. No manual operation is required and the efficiency of the purification equipment will not be affected. The HEPA filter 17 is limited by the sealing clamping plate 14 connected by the driving component 16 and the spring 15. The guide seat 13 cooperates with the sliding of the through groove 12 to realize the rapid replacement of the HEPA filter 17 without stopping the machine, which reduces the operating steps of personnel and improves the efficiency of the purification equipment in purifying the air in the pharmaceutical workshop.

[0028] See also Figure 1 , wherein: a control panel 18 is fixedly installed on the front of the filter box 1 , and the servo motor 7 , the fan 5 and the driving assembly 16 are all electrically connected to the control panel 18 .

[0029] In the present invention, the setting of the control panel 18 allows the user to operate the device more simply and quickly, thereby reducing the steps required by the user to operate, thereby improving the purification efficiency of the air in the pharmaceutical workshop.

[0030] See also Figure 1 , wherein: the front and back sides of the filter box 1 are detachably connected with baffles 19 , and the two baffles 19 are respectively located on the opposite sides of the two through slots 12 .

[0031] In the present invention, the baffle 19 can seal the through groove 12, further improving the sealing between the HEPA filter 17 and the filter box 1, and also improving the aesthetics.

[0032] See also Figure 2 and 3 , wherein: a slide bar 20 is fixedly connected to the top of the bearing seat 8 , and the slide bar 20 is slidably connected to the inner wall of the filter box 1 .

[0033] In the present invention, the setting of the slide bar 20 can limit the bearing seat 8, so that the bearing seat 8 is always located inside the filter box 1 and keeps stable movement.

[0034] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto.
