Description

Technical Field

[0001] The invention relates to the technical field of laboratory cabinets, in particular to a laboratory cabinet with integrated filtering and purification functions. Background Art

[0002] Advanced laboratories are inseparable from professional laboratory cabinets. Since the laboratory is a special working environment, it will be exposed to various chemical substances during the experiment, so it is necessary to choose a professional laboratory cabinet.

[0003] However, not all laboratories will choose the same countertops, because the needs of each laboratory are completely different. Some laboratories may need some countertops with better load-bearing capacity, while some laboratories need some laboratory cabinets with strong corrosion resistance. At the same time, the laboratory cabinets also need to treat the sewage generated during use;

[0004] For example, the patent with publication number CN117181335A mentions that the used water in the laboratory is passed through the filter screen inside the pool to enter the sewage pipe, and the first water pump is driven to extract water from the water tank through the straight pipe. The water flows through the connecting pipe and the water pipe through the nozzle to spray the upper surface of the cabinet body to clean the sewage on the surface and prevent the sewage from remaining on it. The sewage is filtered for impurities through the filter plate and enters the filter device. The sewage is purified through the PP cotton filter layer, the activated carbon layer, the ultrafiltration membrane, and the reverse osmosis device. Then the second water pump is driven to extract the purified water, and the water flows through the U-shaped pipe to enter the filter device for filtering again, thereby ensuring that the sewage is filtered and purified multiple times. However, the sewage impurities are not distinguished during the purification process, resulting in the components used for filtering being under load for a long time, and the service life is shortened;

[0005] For this purpose, we propose laboratory cabinets with integrated filtration and purification functions. Summary of the invention

[0006] The object of the present invention is to provide a laboratory cabinet with integrated filtering and purification functions to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laboratory table cabinet with integrated filtering and purification functions, comprising a counter, a sink and a flushing faucet, wherein the countertop is provided with a sink, a flushing faucet is provided on the top of the counter and located at the side of the sink, a rotary flushing chamber and a purification chamber are respectively provided in the counter from top to bottom, a filter tank is provided in the purification chamber, a slag storage box is provided in the purification chamber and located at the side of the filter tank, and a split tank is fixed to the top of the slag storage box by bolts;

[0008] A rotating flushing mechanism is fixed in the rotary flushing cavity by bolts, and the bottom of the water tank is connected with the rotating flushing mechanism through a pipeline.

[0009] Furthermore, the rotary flushing mechanism includes a shell, a through pipe and a rotary barrel. The top inner wall of the rotary flushing chamber is fixed with the shell by bolts, the through pipe is fixedly connected to the inner walls on both sides of the shell, a rotary barrel is movably connected to the outer wall of the through pipe inside the shell, a motor is fixed with a gear at one end of the motor and meshes with the teeth on the outer wall of the rotary barrel, and a flushing channel is fixed with bolts inside the shell and at the top of the rotary barrel.

[0010] Furthermore, one side of the shell and the through pipe end are connected to the split tank through a connecting pipe, a water pump is fixed in the vortex cavity by bolts, and the water outlet of the water pump is connected to the shell, and the water inlet of the water pump is connected to the filter tank.

[0011] Furthermore, a filter layer is installed in the filter tank, a sewage outlet is provided on the filter tank and at the bottom of the filter layer, and one side of the split tank is connected to the filter tank through a connecting pipe.

[0012] Furthermore, a slide is slidably connected in the bottom slide of the purification chamber, a locking platform is fixedly connected to the top of the slide, a locking buckle is threadedly connected to one side of the locking platform, and the filter tank and the slag storage box are both placed in the locking platform.

[0013] Furthermore, a second motor is fixed to the top of the split tank by bolts, a transmission shaft is movably connected to the inner wall of the split tank, an output end of the second motor passes through the split tank and is connected to the transmission shaft, a rotary arm is symmetrically and movably connected to the outer wall of the transmission shaft, and a counterweight ball is fixed to one end of the rotary arm by welding.

[0014] Furthermore, a lifting plate is slidably connected in the split tank and located on the transmission shaft, a flow channel is opened on the lifting plate, a filter shell is welded and fixed on the top of the lifting plate and located on the outer wall of the transmission shaft, and filter holes are evenly opened on the filter shell.

[0015] The working method of this laboratory cabinet with integrated filtration and purification function is:

[0016] The sewage generated by the experiment is discharged from the sink into the shell. The motor drives the rotary barrel to rotate, and the sewage flows into the inner side of the rotary barrel. As the rotary barrel rotates, the solid impurities of the sewage adsorbed by the ceramic layer on the outer wall of the rotary barrel adhere to the outer wall and come to the bottom of the flushing channel. The purified water extracted by the water pump is discharged into the flushing channel, and is sprayed onto the surface of the rotary barrel from the outlet side after being pressurized, and the adhered solid impurities are washed down into the through pipe, and finally come to the split tank with the water flow;

[0017] The sewage intercepted by the impurities flows into the filter tank through the connecting pipe at the bottom of the shell, and is screened and purified step by step through the filter layers installed in the filter tank, and then discharged from the sewage outlet. The drainage is also sucked by the water pump for recycling.

[0018] For sewage with a high net impurity content discharged into the split tank, motor 2 drives the entire transmission shaft to rotate, and the swing arm connected to the outer wall of the transmission shaft drives the counterweight ball to be suspended in the air. At the same time, the swing arm is used to expand and push the lifting plate up to seal the bottom of the entire filter shell. While the entire filter shell rotates, the sewage is thrown out and enters the filter tank for treatment through the connecting pipe. The dehydrated impurities come to the outer wall of the filter shell. As the speed of the transmission shaft decreases, the height of the lifting plate decreases, and the gap produced cooperates with the rotation of the filter shell, and finally the dehydrated impurities are discharged into the slag box. The slide must be pulled out regularly to clean the slag box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the sewage discharged from the laboratory cabinet is classified and controlled to avoid the long-term adsorption of solid impurities by the installed related filter components, which reduces the purification effect and shortens the service life of the filter components. For this reason, the impurities discharged into the sewage are first intercepted and treated by a rotating flushing mechanism installed in the rotary flushing cavity. Along with the cleaning of the flushing channel, the impurities will be discharged into the split tank along the through pipe, and automatically discharged into the slag storage box after centrifugal dehydration. As for the filtered sewage, the filter layer installed in the filter tank will fully treat the sewage. The classified control improves the overall purification effect and efficiency of the laboratory cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-6 , the present invention provides a technical solution:

[0032] Example 1: Laboratory cabinet with integrated filtration and purification function. Compared with simple filtration treatment, the wastewater produced by laboratory operators contains different impurities, some of which are soluble in water and some are insoluble in water. Direct unification will cause certain damage to the filter components installed in the laboratory cabinet. Figure 1 and Figure 2 As shown, the filter tank 8 and the slag storage box 11 are classified and controlled in the cabinet, and the sewage and the impurities contained therein are filtered and processed in an integrated manner to improve the filtering efficiency;

[0033] The sewage flows through the sink 2 arranged on the top of the counter 1 into the rotary flushing cavity 4 and the rotating flushing mechanism 6. At the same time, the flushing faucet 3 installed is connected to the external water inlet pipe, such as Figure 5 As shown, the entire rotating flushing mechanism 6 is provided with a rotating barrel 604, both sides of which extend inwardly, and sewage is directly discharged into the inner side of the rotating barrel 604, and a ceramic layer is evenly provided on the inner wall of the rotating barrel 604, and the ceramic layer has relatively large holes, so that impurities in the sewage are continuously lifted up with the rotation of the rotating barrel 604, and finally reach the bottom of the flushing channel 605;

[0034] At this time, the sewage purified by the filter tank 8 is pumped into the flushing channel 605 by the water pump 7 again, and is sprayed to the outer wall of the rotary barrel 604 after being pressurized. As the water flows from the outer wall of the rotary barrel 604 to the inside, the impurities adsorbed on the inner wall of the rotary barrel 604 are washed down to the through pipe 602, and enter the split tank 12 along with the water flow;

[0035] The sewage intercepted and filtered by the rotary drum 604 enters the filter tank 8 along the pipe connected to the bottom of the shell 601. Figure 6 As shown, the filter layer 9 is installed in the entire filter tank 8, and the filter layer 9 is composed of a composite filter component such as a PP cotton filter layer, an activated carbon layer, an ultrafiltration membrane, a reverse osmosis membrane, etc., and a fixing frame is arranged on its outer wall. When it is replaced later, it is only necessary to open the top cover of the filter tank 8, and the replacement is relatively simple. The sewage that has been intercepted and filtered is finally discharged from the counter 1 along the sewage outlet 10;

[0036] To facilitate the replacement and installation of the filter layer 9, a slide 22 is slidably connected to the inner wall of the bottom of the purification chamber 5, and a locking platform 21 is fixedly connected to the slide 22. The entire filter tank 8 and the slag storage box 11 are installed on the locking platform 21, and the two are fixed by a threaded lock buckle 23. At the same time, the length of the pipes installed on the filter tank 8 and the split tank 12 must meet the maximum stretching distance of the slide 22 to avoid the connecting pipes from falling off when the slide 22 is pulled out.

[0037] Embodiment 2: For solid impurities generated by sewage filtration, the pipe connected to the end of the through pipe 602 is connected to the split tank 12, and the impurities enter the split tank 12 along with the water flow. Figure 7 and Figure 8 As shown, the motor 2 13 is installed on the top of the entire split tank 12, and the motor 1 603 is fixed to the top inner wall of the shell 601 by bolts, and the gear connected to the end of the motor 1 603 is meshed with the tooth pattern on the outer wall of the rotary barrel 604, which drives the rotary barrel 604 to rotate, and the installation of the motor 2 13 drives the transmission shaft 14 in the split tank 12 to rotate;

[0038] Since the outer wall of the transmission shaft 14 is symmetrically rotated with the swing arm 16, the swing arm 16 is "L" shaped, and the transmission shaft 14 rotates with the motor 13 working, the rotation of the transmission shaft 14 causes the weight ball 17 connected to the end of the entire swing arm 16 to unfold and rise, and when the speed of the motor 13 decreases, the rotation height of the weight ball 17 decreases;

[0039] A lifting plate 18 is also slidably connected to the outer wall of the transmission shaft 14, and the outer wall of the transmission shaft 14 located on the top of the lifting plate 18 is fixedly connected to the filter housing 15 through a bracket. The outer wall of the entire filter housing 15 is evenly provided with filter holes to facilitate the rapid passage of water flow, but to intercept solid impurities. The lifting plate 18 is located at the bottom of the filter housing 15, and the outer wall at the bottom of the lifting plate 18 is symmetrically rotatably connected to a connecting rod 20, and one end of the connecting rod 20 is movably connected to the end of the swing arm 16;

[0040] Whenever the swing arm 16 rotates at a high speed, the swing arm 16 rotates and expands to push the connecting rod 20 to rotate, and finally pushes the entire lifting plate 18 to slide upward on the outer wall of the transmission shaft 14, and the lifting plate 18 rises to squeeze the bottom of the filter housing 15 to form a closed container, and the sewage is discharged into the filter housing 15 along with impurities. The filter housing 15 rotates at a high speed, and the sewage continuously penetrates the outer wall of the filter housing 15 to the inner side of the split tank 12, and is discharged into the filter tank 8 again through the connecting pipe;

[0041] The impurities intercepted on the outer wall of the filter housing 15 are continuously enriched, and the thickness of the inner wall of the entire filter housing 15 decreases from top to bottom, causing the heavier impurities to slide downward continuously when the filter housing 15 rotates, and finally reach the junction of the lifting plate 18 and the filter housing 15. After a long period of high-speed centrifugal dehydration, the impurities at this time begin to become dry, and it is necessary to discharge the impurities into the slag storage box 11, and there is a cover shell on the top of the entire lifting plate 18;

[0042] When the speed of the entire motor 2 13 decreases, the speed of the transmission shaft 14 decreases, resulting in a decrease in the lifting height of the counterweight ball 17 on the entire rotary arm 16. At this time, the rotary arm 16 and the connecting rod 20 drive the entire lifting plate 18 to slide downward on the outer wall of the transmission shaft 14, forming a gap between the filter shell 15 and the lifting plate 18. With the low-speed rotation of the rotary shell, the dehydrated impurities are directly discharged from the bottom of the rotary shell, and are successfully intercepted by the cover shell and discharged from the flow channel 19 into the slag storage box 11. After centrifugal dehydration, they are automatically discharged into the slag storage box 11. Classification control improves the overall purification effect and efficiency of laboratory cabinets;

[0043] Likewise, the entire slag storage box 11 also needs to be manually cleaned regularly, and the inner wall of the entire slag storage box 11 is coated with an anti-corrosion coating to extend the service life.

[0044] The working principle of the present invention is as follows: the sewage generated by the experiment is discharged from the water tank 2 into the housing 601, the motor 1 603 drives the rotary barrel 604 to rotate, and the sewage flows into the inner side of the rotary barrel 604. As the rotary barrel 604 rotates, the sewage solid impurities adsorbed by the ceramic layer on the outer wall of the rotary barrel 604 adhere to the outer wall and come to the bottom of the flushing channel 605. The purified water extracted by the water pump 7 is discharged into the flushing channel 605, and is sprayed onto the surface of the rotary barrel 604 from the outlet side after being pressurized, and the adhered solid impurities are washed down into the through pipe 602, and finally come to the split tank 12 along with the water flow;

[0045] The sewage intercepted by the impurities flows into the filter tank 8 through the bottom connecting pipe of the housing 601, is screened and purified step by step by the filter layer 9 installed in the filter tank 8, and is discharged from the sewage outlet 10. The drainage is simultaneously accompanied by the suction of the water pump 7 for recycling;

[0046] As for the sewage with a high net impurity content discharged into the split tank 12, the motor 2 13 drives the entire transmission shaft 14 to rotate, and the swing arm 16 connected to the outer wall of the transmission shaft 14 drives the counterweight ball 17 to be suspended in the air. At the same time, the swing arm 16 is used to expand and push the lifting plate 18 to rise, so as to seal the bottom of the entire filter shell 15. While the entire filter shell 15 rotates, the sewage is thrown out and enters the filter tank 8 for treatment through the connecting pipe. The dehydrated impurities come to the outer wall of the filter shell 15. As the speed of the transmission shaft 14 decreases, the height of the lifting plate 18 is reduced at this time, and the gap generated cooperates with the rotation of the filter shell 15, and finally the dehydrated impurities are discharged into the slag storage box 11. The slide 22 needs to be pulled out regularly to clean the slag storage box 11.
