Description

Technical Field

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

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

[0003] Laboratories often generate a large amount of waste gas when operating. 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 odor. First, the ventilation duct is installed in the laboratory, and then the laboratory air enters the ventilation duct through the primary purification net, and the odor in the laboratory air can be adsorbed and sterilized through the action of the activated carbon adsorption net and the sterilization net. Then, the flow of laboratory air is enhanced by the action of the exhaust fan, and it can mix and react with the odor emitted by the deodorization box, thereby improving the deodorization effect of the laboratory air. Then, the deodorization work is performed again through 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 purification device has the following problem: when the purification device is filtering, since the device is in continuous operation, the surface of the filter screen is prone to excessive accumulation of impurities, which deteriorates the impurity filtering effect of the filter screen, thereby causing the adsorption effect of the filter screen 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, because the device is constantly running, 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.

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 shell, and 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 at the driving end of the rotating motor 1, and two sets of bevel gears 2 are meshedly arranged on the upper end of the rotating motor 1, and connecting rods 2 are fixedly installed at the ends of the two sets of bevel gears 2 away from each other, and the ends of the connecting rods 2 away from the bevel gears 2 are fixedly connected to the incomplete gear, and the connecting rods 2 are 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 adsorption barrels, and the connecting rod three passes through one end of the adsorption barrel and is fixedly installed with a piston disk on the outside, and 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 outer side 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 pipeline, when it is necessary to purify the waste inside the laboratory, the device is operated as a whole by operating the control cabinet, and 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 rotating motor to rotate, the rotating 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. The incomplete gear meshing tooth groove drives the two groups of sliding blocks to move back and forth alternately, and then drives the piston disk to reciprocate in the adsorption barrel. The piston disk reciprocates on both sides of the exhaust groove, so that the gas in the adsorption barrel is fully in contact with the adsorption plate in the adsorption barrel. Since the interval between each rotation of the rotating motor 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 parts are squeezed and stretched respectively, and the two sets of connecting rods 2 are moved back and forth under the action of the two sets of elastic parts, further improving the adsorption efficiency while reducing the loss of the motor. When the two sets of connecting rods 2 move back and forth, the balls at the upper ends of the two sets of connecting rods 2 slide in the spiral grooves inside the adsorption plate, so that the adsorption plate rotates back and forth in the adsorption barrel, and then the air in the adsorption barrel is tangent to the holes of the adsorption plate, so that the adsorption force of the adsorption plate is more uniform and the adsorption effect is better. ;

[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.

[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 a plurality of 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 the 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 achieving a better purification effect inside the reaction shell.

[0012] Furthermore, a connection frame is fixedly installed at one end of the reaction shell near the air inlet, and a sterilization net is slidably installed inside the connection 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 with materials having 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 process, thereby making the microorganisms inactive, the purpose of sterilization is achieved, and the purification effect inside the reaction shell is 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 escape 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 need exhaust in biological and chemical laboratories through pipelines, when it is necessary to purify the waste inside the laboratory, the device is operated as a whole by operating the control cabinet, and the exhaust gas enters the air inlet through the air inlet, is filtered by various filtering devices, and then 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, and the rotating motor starts to rotate by starting. The rotation of the rotating motor drives the bevel gear one 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 two groups of sliding blocks are driven to rotate alternately through the meshing tooth grooves of the incomplete gears. The piston plate moves back and forth in the adsorption barrel, and the piston plate reciprocates on both sides of the exhaust groove to make 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 rotating motor 1 rotates one circle to drive the two groups of connecting rods 2 to reciprocate, the two groups of elastic parts are squeezed and stretched respectively. Under the action of the two groups of elastic parts, the two groups of connecting rods 2 are reciprocated, so as to further improve the adsorption efficiency and reduce the loss of the motor. When the two groups of connecting rods 2 reciprocate, the balls on the upper ends of the two groups of connecting rods 2 slide in the spiral groove inside the adsorption plate, so that the adsorption plate rotates back and forth in the adsorption barrel, so that the air in the adsorption barrel is tangent to the holes of the adsorption plate, so that the adsorption force of the adsorption plate is more uniform and the adsorption effect is better.
