Description

Technical Field

[0001] The present invention relates to the technical field of purification devices, in particular to a laboratory air adsorption purification device. Background Art

[0002] Air purification refers to providing comprehensive solutions to various indoor environmental problems, such as sterilization and disinfection, dust reduction and haze removal, and removal of harmful decoration residues and odors, to improve living and working conditions and enhance physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gases, mold, particulate matter, decoration residues, etc.

[0003] Laboratories often produce a large amount of waste gas when conducting laboratory work. If these waste gases are directly discharged into the air, they will cause pollution to the environment. Therefore, special purification equipment is generally prepared in the laboratory to purify the waste gas before discharging it into the atmosphere.

[0004] The existing Chinese patent with publication number CN218307072U discloses a laboratory air purification device with the function of removing odors. First, the ventilation duct is installed in the laboratory, and then the laboratory air enters the ventilation duct through the primary purification net. The activated carbon adsorption net and the sterilization net can adsorb and sterilize the odor in the laboratory air. Then, the flow of laboratory air is enhanced by the action of the exhaust fan, which can mix and react with the odor emitted by the deodorization box, thereby improving the deodorization effect of the laboratory air. Then, the odor is removed again by the cooperation of the ultraviolet sterilization lamp and the photocatalyst aluminum-based net, and finally discharged through the final purification net.

[0005] However, the above-mentioned purification device has the following problem: when the purification device is filtering, since the device is in continuous operation, impurities are easily accumulated on the surface of the filter, which makes the impurity filtering effect of the filter worse, thereby causing the adsorption effect of the filter to deteriorate.

[0006] Therefore, a laboratory air adsorption purification device is needed. Summary of the Invention

[0007] In order to solve all or part of the above problems, the purpose of the present invention is to provide a laboratory air adsorption purification device, so as to solve the problem that when the purification device is filtering, due to the continuous operation of the device, the surface of the filter screen is prone to excessive accumulation of impurities, which makes the impurity filtering effect of the filter screen worse, thereby causing the adsorption effect of the filter screen to worsen.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laboratory air adsorption purification device, comprising a purification device, an auxiliary exhaust device is provided at the upper end of the purification device, a control cabinet is provided on one side of the purification device, the purification device comprises a reaction shell, an air inlet is provided at one end of the reaction shell, an exhaust port is provided at the other end of the reaction shell, an adsorption component is provided inside the reaction shell, the adsorption component is connected to the air inlet, and the adsorption component comprises a U-shaped plate, two groups of elastic members are fixedly installed inside the U-shaped plate, one end of the two groups of elastic members are fixedly installed with sliding blocks, a slide groove is provided on the opposite side of the two groups of sliding blocks, and the interiors of the two groups of sliding blocks are An incomplete gear is rotatably installed, and tooth grooves are provided on the upper ends of the two sets of sliding blocks, which match the incomplete gears. A connecting rod 1 is rotatably installed on one side of the incomplete gear, and the end of the connecting rod 1 away from the incomplete gear is fixedly connected to the reaction housing. A rotating motor 1 is fixedly installed inside the U-shaped plate, and the interval between each rotation of the rotating motor 1 is 3 seconds. A bevel gear 1 is fixedly installed on the driving end of the rotating motor 1, and two sets of bevel gears 2 are meshed with each other on the upper end of the rotating motor 1. A connecting rod 2 is fixedly installed on the ends of the two sets of bevel gears 2 away from each other, and the end of the connecting rod 2 away from the bevel gear 2 is fixedly connected to the incomplete gear, and the connecting rod 2 is slidably connected to the slide groove 1;The ends of the two sets of sliding blocks away from the elastic member are fixedly installed with connecting rod three, and the ends of the two sets of connecting rod three away from the sliding blocks are slidably provided with an adsorption barrel, the connecting rod three passes through one end of the adsorption barrel and is fixedly installed with a piston disk on the outside, the piston disk matches the inner side of the adsorption barrel, and multiple sets of adsorption plates are rotatably installed on the inner side of the adsorption barrel, and the adsorption plates are rotatably connected to the adsorption barrel, the connecting rod three passes through multiple sets of adsorption plates and multiple sets of balls are fixedly installed on the outside of the connecting rod three, and spiral grooves are opened inside the adsorption plates, and the spiral grooves match the balls. When the balls on the connecting rod three come into contact with the spiral grooves, the adsorption plates are The ball moves back and forth in the spiral groove, driving the adsorption plate to rotate in the adsorption barrel. An exhaust groove is provided at the lower end of the adsorption barrel. Since the air inlet is connected to the exhaust reagent cabinet, fume hood and various facilities requiring exhaust in the biological and chemical laboratories through a pipe, when the waste purification process inside the laboratory is required, the device is operated as a whole by operating the control cabinet. The exhaust gas enters the air inlet through the air inlet, is filtered by various filtering devices, and is discharged into the adsorption component for bacteria and microorganism adsorption treatment. In the initial state, the two sets of piston discs are respectively located on both sides of the exhaust groove. By starting the rotating motor, the rotation of the rotating motor drives the bevel gear 1 to rotate, and then drives the two sets of connecting rods 2 to rotate in opposite directions. The two sets of connecting rods 2 drive the incomplete gears to rotate in opposite directions. The meshing tooth grooves of the incomplete gears drive the two sets of sliding blocks to move back and forth alternately, thereby driving the piston disc to reciprocate in the adsorption barrel. The reciprocating motion of the piston disc on both sides of the exhaust groove makes the gas in the adsorption barrel fully contact with the adsorption plate in the adsorption barrel. Since the interval between each rotation of the rotating motor 1 is 3 seconds, When the motor rotates one revolution, driving the two sets of connecting rods to move back and forth, the two sets of elastic members are squeezed and stretched, respectively, causing the two sets of connecting rods to reciprocate under the action of the two sets of elastic members, further improving adsorption efficiency while reducing motor losses. As the two sets of connecting rods reciprocate, the balls at the upper ends of the two sets of connecting rods slide in the spiral grooves inside the adsorption plate, causing the adsorption plate to rotate back and forth within the adsorption barrel. This, in turn, allows the air in the adsorption barrel to be tangent to the holes in the adsorption plate, making the adsorption force of the adsorption plate more uniform and improving the adsorption effect.

[0009] Furthermore, sliders are installed at the upper and lower ends of the two groups of sliding blocks, and the sliders are matched with the U-shaped plate. When the two groups of sliding blocks move back and forth under the action of incomplete gears, the sliders slide in the U-shaped plate, maintaining its stability while making the air adsorption effect in the adsorption barrel better.

[0010] Furthermore, multiple groups of annular grooves are provided on the inner side of the adsorption barrel, and the annular grooves match the adsorption plate. When the two groups of connecting rods move back and forth, the balls at the upper ends of the two groups of connecting rods slide in the spiral grooves inside the adsorption plate, causing the adsorption plate to rotate back and forth inside the annular grooves of the adsorption barrel. The stability of the adsorption plate is maintained by the annular grooves, thereby achieving better adsorption effect of the adsorption plate.

[0011] Furthermore, a primary filter cotton is fixedly installed inside the air inlet, an exhaust pipe is provided at the lower end of the reaction shell, and multiple sets of anti-slip support feet are fixedly installed at the lower end of the reaction shell. The air discharged into the air inlet from the exhaust reagent cabinets, fume hoods and various facilities requiring exhaust in biological and chemical laboratories is preliminarily filtered through the primary filter cotton. The primary filter cotton utilizes its loose fiber structure with numerous pores. When air passes through, large particles of dust, hair, larger debris and other impurities will be intercepted on the surface of the filter cotton or stuck in the pores because they cannot pass through the gaps between the fibers smoothly, thereby making the purification effect inside the reaction shell better.

[0012] Furthermore, a connecting frame is fixedly installed at one end of the reaction shell near the air inlet, and a sterilization net is slidably installed inside the connecting frame. The upper end of the sterilization net is slidably connected to the reaction shell, and the sterilization net is fixedly connected to the reaction shell by screws. The air filtered by the primary filter cotton is sterilized by the sterilization net. A filter net woven from materials with bactericidal properties such as silver ions is usually used. Since silver ions can destroy the cell structure of microorganisms such as bacteria and fungi and interfere with their normal metabolic processes, the microorganisms are inactivated, thereby achieving the purpose of sterilization and making the purification effect inside the reaction shell better.

[0013] Furthermore, two groups of air inlet holes are opened on the side of the connecting frame away from the air inlet, and the two groups of air inlet holes are connected to the two groups of adsorption barrels. The air filtered by the primary filter cotton and the sterilization net is discharged into the two groups of adsorption barrels through the two groups of air inlet holes for adsorption treatment, thereby adsorbing and purifying tiny particles and some microorganisms.

[0014] Furthermore, two groups of ultraviolet sterilization lamps are fixedly installed inside the reaction shell, and multiple groups of connecting nets are fixedly installed at the lower ends of the ultraviolet sterilization lamps. The upper ends of the connecting nets are evenly coated with photocatalyst materials, which are further formed into photocatalyst aluminum-based nets. The air after adsorption treatment by the two groups of adsorption barrels is sterilized by the ultraviolet sterilization lamps and the photocatalyst materials on the connecting nets. Under the irradiation of ultraviolet rays, the photocatalyst will be activated to produce active substances such as hydroxyl free radicals and superoxide anion free radicals with strong oxidizing properties. These active substances can undergo oxidation reactions with organic pollutants remaining in the air, decomposing them into harmless small molecules such as carbon dioxide and water, further purifying the air and removing odors. At the same time, it can also kill microorganisms that may have escaped the net again, and further purify the air after adsorption treatment.

[0015] Furthermore, a deodorization device is fixedly installed inside the reaction shell, and the deodorization device includes a rotating motor 2. Two groups of deodorization brushes are fixedly installed on the driving end of the rotating motor 2. The two groups of deodorization brushes are located directly below the two groups of exhaust slots. The deodorization brushes are driven to rotate by the rotating motor 2, and the air discharged from the exhaust slots is deodorized by the deodorization brushes, so that the air discharged from the external environment will not affect the atmosphere.

[0016] Furthermore, an exhaust fan is provided at one end of the reaction shell near the exhaust port, a cross frame is fixedly installed at one end of the exhaust fan, the cross frame is fixedly connected to the reaction shell, and the air in the reaction shell is discharged through the exhaust fan.

[0017] Furthermore, the auxiliary exhaust device is connected to the interior of the reaction shell. When emergency exhaust is required, the exhaust pressure of the reaction shell is dispersed by opening the auxiliary exhaust device to prevent damage to the device caused by excessive pressure inside the reaction shell.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention proposes a laboratory air adsorption purification device. Since the air inlet is connected to the exhaust reagent cabinets, fume hoods and various facilities that require exhaust in biological and chemical laboratories through pipes, when it is necessary to purify the waste inside the laboratory, the control cabinet is operated to operate the device as a whole. The exhaust gas enters the air inlet through the air inlet, is filtered by various filtering devices, and is discharged into the adsorption component for bacteria and microorganism adsorption treatment. In the initial state, the two groups of piston disks are respectively located on both sides of the exhaust groove. By starting the rotary motor, the rotation starts, and the rotation of the rotary motor drives the bevel gear to rotate, and then drives the two groups of connecting rods to rotate in opposite directions. The two groups of connecting rods drive the incomplete gears to rotate in opposite directions, and the meshing tooth grooves of the incomplete gears drive the two groups of sliding blocks to rotate alternately. After that, it moves, thereby driving the piston disk to move back and forth in the adsorption barrel. The piston disk reciprocates on both sides of the exhaust groove, so that the gas in the adsorption barrel is in full contact with the adsorption plate in the adsorption barrel. Since the interval between each rotation of the rotating motor 1 is 3 seconds, when the rotating motor 1 rotates one circle to drive the two sets of connecting rods 2 to move back and forth, the two sets of elastic members are squeezed and stretched respectively. Under the action of the two sets of elastic members, the two sets of connecting rods 2 are moved back and forth, further improving the adsorption efficiency while reducing the loss of the motor. While the two sets of connecting rods 2 reciprocate, the balls at the upper ends of the two sets of connecting rods 2 slide in the spiral groove inside the adsorption plate, causing the adsorption plate to rotate back and forth in the adsorption barrel, thereby making the air in the adsorption barrel tangent to the holes of the adsorption plate, making the adsorption force of the adsorption plate more uniform and the adsorption effect better.

Two groups of bevel gears 174 are meshed on the upper end of the rotating motor 173. The ends of the two groups of bevel gears 174 away from each other are fixedly installed with a connecting rod 2 1741. The end of the connecting rod 2 1741 away from the bevel gear 2 174 is fixedly connected to the incomplete gear 1724, and the connecting rod 2 1741 is slidably connected to the slide groove 1721.The ends of the two groups of sliding blocks 172 away from the elastic member 1711 are fixedly installed with a connecting rod 3 175, and the ends of the two groups of connecting rods 3 175 away from the sliding blocks 172 are slidably provided with an adsorption barrel 176.
