Description

Technical Field

[0001] The utility model relates to the technical field related to purification and ventilation, and specifically to a purification and ventilation device for a smart laboratory. Background Art

[0002] Driven by new-generation information technologies such as 5G, artificial intelligence, the Internet of Things, and digital twins, China's laboratory industry is experiencing leapfrog development. Building "smart laboratories" has become a consensus, and smart laboratories are an inevitable trend of development. Human wisdom and intelligent technology are integrated into the design, construction, operation, management, and development of laboratories, enabling laboratories to play their role in technical support in related fields. In order to protect the health of personnel, ensure the accuracy of experiments, and improve the working environment, during the use of smart laboratories, clean air needs to be injected into the smart laboratories through purification and ventilation devices. For example, the patent document with publication number CN213348156U in the prior art provides a smart laboratory microbial purification and ventilation device. The device can drive the fixing ring and the brush at its bottom to move left and right through the second fixing rod. The brush can clean the surface of the filter plate, avoiding manual cleaning of the filter plate, which is time-consuming and labor-intensive, and saving a lot of time.

[0003] However, the device can only brush off the impurities on the surface of the filter plate through the brush, but cannot recover these raised impurities. After a certain period of time, these dusts will still fall on the surface of the filter plate, causing the filter plate to be blocked. This obviously has a major defect. For this reason, we proposed a smart laboratory purification and ventilation device. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This intelligent laboratory purification and ventilation device, through the meshing connection between the driving gear and the driven gear, enables the driving motor to drive the rotating frame to rotate on the upper end of the filter plate. Since the air moves faster at the filter plate than in each filter chamber, the pressure difference between the rotating frame and the filter plate changes, so that impurities on the surface of the filter plate can be pushed into the rotating frame. With the help of the air guide cavity, the limit rotating frame and the slag discharge pipe, these impurities can be recovered to avoid further clogging of the filter plate and improve the filtering effect of the filter plate.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-7 The utility model provides a technical solution: a smart laboratory purification and ventilation device, including a processing chamber 1, an air inlet pipe 15 and an exhaust pipe 13 are fixedly installed on the upper end and outer wall of the processing chamber 1 respectively, a fan 16 is fixedly installed in the air inlet pipe 15, a filter plate 2 and a plurality of filter chambers 3 are provided in the inner cavity of the processing chamber 1, a rotating rod 27 is rotatably installed on the upper end of the inner cavity of the processing chamber 1, a rotating frame 23 is fixedly installed on the lower end of the rotating rod 27, the length of the rotating frame 23 matches the radius of the filter plate 2, and the lower end of the rotating frame 23 is in contact with the upper end of the filter plate 2, and a rotating frame 23 is fixedly installed on the lower side of the inner cavity of the rotating frame 23. A brush plate 271 is in surface contact, a slag discharge pipe 12 is fixedly installed on the outer wall of the processing bin 1, a limit rotating frame 24 fixedly connected to the slag discharge pipe 12 is provided in the processing bin 1, the rotating rod 27 is rotatably installed in the limit rotating frame 24, an air guide cavity 272 which is interconnected with the rotating frame 23 is opened on the periphery of the rotating rod 27, the air guide cavity 272 is provided in the limit rotating frame 24, a driven gear 28 is fixedly installed on the periphery of the upper end of the rotating rod 27, a driving motor 25 is fixedly installed on the upper end of the processing bin 1, and a driving gear 26 which is meshed with the driven gear 28 is fixedly installed on the lower end of the driving motor 25 through its output shaft.

[0028] Working principle: When the air inlet pipe 15 guides the outside air into the processing chamber 1 through the fan 16, the dust and other solid impurities in the air can be filtered through the filter plate 2.

[0029] When it is necessary to recover impurities on the surface of the filter plate 2, the drive motor 25 is started, and through the active gear 26 and the driven gear 28, and in conjunction with the rotating rod 27, the drive motor 25 can drive the rotating frame 23 to rotate on the surface of the filter plate 2 through its output shaft. Since the filter plate 2 is a primary filtration, it mostly adopts a mesh structure, and each filter chamber 3 is a deep filtration, which mainly adopts activated carbon and microbial soil. This makes the air flow rate in the filter plate 2 greater than the flow rate in the filter chamber 3, so that when the rotating rotating frame 23 is aligned with the surface of the filter plate 2, a pressure difference change will occur at the alignment point, so that the impurities on the surface of the filter plate 2 can be pushed upward into the rotating frame 23, and then in conjunction with the air guide cavity 272, the limiting rotating frame 24 and the slag discharge pipe 12, the impurities can be discharged outward, thereby improving the impurity recovery effect and the recovery effect of the filter plate 2.

[0030] As a further description of the above technical solution: a first positioning ring 21 is fixedly installed on the upper side of the inner cavity of the processing chamber 1, the filter plate 2 is plugged and installed on the lower side of the first positioning ring 21, and a positioning clamping ring 22 is provided on the lower side of the filter plate 2 to be clamped with the first positioning ring 21.

[0031] Specifically, the filter plate 2 is installed on the lower side of the first positioning ring 21. When installing the filter plate 2, there is no need to adjust the position of the rotating frame 23, which improves the installation efficiency of the filter plate 2. The filter plate 2 can be positioned on the lower side of the first positioning ring 21 through the positioning clamp 22.

[0032] As a further description of the above technical solution: multiple second positioning rings 31 are slidably installed in the processing chamber 1, the filter chamber 3 is plugged into the upper end of the second positioning ring 31, and a limiting slide rail 32 is fixedly installed on the inner wall of the processing chamber 1. A limiting slide groove 33 that is slidably connected to the limiting slide rail 32 is provided on the outer periphery of the second positioning ring 31; a limiting rotation hole 36 is provided on one side of the upper end of the second positioning ring 31, and a threaded rod 35 is fixedly installed on the inner wall of the processing chamber 1 through a connecting seat 34. The threaded rod 35 is provided in the limiting rotation hole 36, and a threaded sleeve 37 threadedly connected to the threaded rod 35 is rotatably installed in the limiting rotation hole 36.

[0033] Specifically, according to the type, number and spacing of the filter chambers 3, the threaded sleeve 37 can be rotated in the limiting rotation hole 36. On the inner wall of the processing chamber 1, the sliding connection between the limiting slide rail 32 and the limiting slide groove 33 restricts the movement direction of the second positioning ring 31, so that the rotating threaded sleeve 37 can drive the second positioning ring 31 to move up and down through the threaded connection between it and the threaded rod 35, thereby achieving the effect of adjusting the position of each second positioning ring 31.

[0034] As a further description of the above technical solution: a water tank 4 is provided at the bottom of the inner cavity of the processing chamber 1, and a first connecting pipe 42 connected to the exhaust pipe 13 is fixedly installed on the surface of the water tank 4, a liquid injection pipe 14 is fixedly installed on the outer wall of the processing chamber 1, and a second connecting pipe 43 connected to the liquid injection pipe 14 is fixedly installed on the periphery of the water tank 4; a ventilation pipe 41 is fixedly installed in the middle of the upper end of the water tank 4, and a limiting sleeve 45 is fixedly installed in the ventilation pipe 41 through a connecting rod, a positioning hole 44 is opened at the bottom of the inner end of the processing chamber 1, and a positioning rod 47 whose lower end is connected to the positioning hole 44 is installed in the limiting sleeve 45, a sealing sleeve 46 is fixedly installed at the bottom of the inner cavity of the water tank 4, and a spring 48 is fixedly installed between the positioning rod 47 and the sealing sleeve 46.

[0035] Specifically, when installing the water tank 4, the positioning rod 47 is lifted upward in the ventilation pipe 41 so that the lower end of the positioning rod 47 moves into the sealing sleeve 46. The water tank 4 is then installed in the processing chamber 1, and the second connecting pipe 43 and the injection pipe 14 are plugged into each other. The positioning rod 47 is released, and the spring 48 restores its deformation, which drives the positioning rod 47 downward and plugs it into the positioning hole 44. The water tank 4 can be positioned in the processing chamber 1. Finally, the first connecting pipe 42 and the exhaust pipe 13 are connected to each other.

[0036] When the ventilation pipe 41 guides the air into the water tank 4 so that the air comes into contact with moisture, the moist air can be discharged to the outside through the first connecting pipe 42 and the exhaust pipe 13;

[0037] Through the second connecting pipe 43 and the liquid injection pipe 14 , the water tank 4 can be replenished with water outside the processing chamber 1 .

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
