Description

Technical Field

[0001] This invention relates to the field of waste liquid treatment, specifically to an integrated waste liquid collection and treatment device. Background Technology

[0002] In hospitals, laboratories and other places, there are often waste liquids generated from testing and experiments. These waste liquids often contain bacteria and pollutants, so appropriate treatment equipment is needed to treat them before they can be discharged.

[0003] Filtration is the most basic operation for treating these waste liquids. For example, an integrated laboratory waste liquid collection and treatment device with publication number CN109179751A filters experimental waste liquids through multiple processes.

[0004] However, the waste liquid in the existing technology is not as easy to filter as ordinary sewage, especially the waste liquid generated in hospitals. This waste liquid often contains blood, sputum, pus and some secretions produced by other diseases. These liquids are generally viscous and are very easy to adhere to filter screens, gauze and other filter components during filtration, thus causing blockage and affecting subsequent filtration work.

[0005] In addition, in order to remove pollutants from the waste liquid, flocculants need to be added to the waste liquid to make the pollutants in the waste liquid coagulate into flocs, and then let them settle to separate the pollutants. In the existing technology, when the liquid is large and deep, the sediment generated in the top layer of liquid often takes a long time to fall to the bottom layer, which increases the sedimentation time and reduces the sedimentation efficiency. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an integrated waste liquid collection and treatment device. By setting up a partition, the waste liquid inside the sedimentation tank is separated according to height before sedimentation. The sediment generated in the top area of ​​the partition falls directly onto the partition, so the sediment at higher positions does not need to be moved to the bottom of the sedimentation tank for sedimentation, which can effectively solve the problems in the prior art.

[0008] (II) Technical Solution

[0010] The sedimentation tank has multiple first slots on its inner wall. The first slots are distributed on the inner walls of both sides of the sedimentation tank. Two first slots of the same height on the inner walls of both sides of the sedimentation tank are grouped together. The first slots are divided into multiple groups according to height. The distance between any two adjacent first slots in any two groups is the same. The outer ends of the two sides of the partition are respectively inserted into two first slots in one group, so that the partition is installed inside the sedimentation tank.

[0011] The partition has a through hole that penetrates the partition. A support plate is provided at the bottom of the partition. The support plate is located directly below the through hole and its size is larger than the through hole. Two connecting rods connected to the partition are fixed at the top of the support plate.

[0012] Furthermore, both the filter box and the sedimentation box have access doors on their front sides via hinges, and each access door is inlaid with a glass plate.

One end of the liquid extraction pipe is connected to the sedimentation box, and a balance pipe with a valve is fixedly installed at the top of the sedimentation box.

[0014] Furthermore, a drain hose with a valve is fixedly installed on one side of the sedimentation tank, and one end of the drain hose extends into the interior of the sedimentation tank and is fixedly fitted with a buoyancy ball.

[0015] Furthermore, a collection box is fixedly provided at the top of the filter box, and a sealing plate is provided at the opening at the top of the collection box. The sealing plate is provided with a hinge assembly that can be hinged to the collection box.

[0016] The bottom of the collection box is fixed with two inclined blocks that allow waste liquid to collect. The bottom of the collection box is also fixed with a connecting channel that extends into the filter box. The connecting channel is located between the two inclined blocks.

[0017] The filter box is equipped with a filter screen that performs a filtering function. The filter screen is located at the bottom of the connecting channel. A second slot is provided on both sides of the inner wall of the filter box, and the two ends of the filter screen are respectively inserted into the two second slots.

[0018] Furthermore, the hinge assembly includes a bracket fixedly disposed on the rear side of the collection box, the bracket having a central rod inside, both ends of which are fixedly connected to the inner wall of the bracket;

[0019] The outer end of the central rod is fitted with a sleeve, and the outer end of the sleeve is fixedly fitted with a connecting plate connected to the sealing plate. Both ends of the sleeve are fitted with a spring, and the two ends of the spring are fixedly connected to the inner wall of the sleeve and the bracket, respectively.

[0020] The outer end of the central rod is inlaid with a first electrode plate, and the inner wall of the sleeve is fixedly provided with a second electrode plate.

[0021] Furthermore, a diversion channel is fixedly provided on the inner wall of the collection box, and a water outlet groove is opened at the position where the bottom end of the diversion channel contacts the inner wall of the collection box, so that the water can flow along the inner wall of the collection box. A water guide pipe connected to the diversion channel is fixedly provided on one side of the collection box, and a solenoid valve electrically connected to the first electrode plate and the second electrode plate is fixedly provided on the water guide pipe.

[0022] The filter box has a water storage tank on the side away from the sedimentation tank. A cover plate is detachably installed on the top of the water storage tank.

One end of each insertion pipe extends into the filter box, and multiple shower heads are fixed on each insertion pipe. The shower heads are located on top of the filter screen and are positioned higher than the bottom of the connecting channel, thereby adding flocculant into the waste liquid.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides an integrated waste liquid collection and treatment device, which has the following beneficial effects:

[0026] 1. By setting up baffles, the waste liquid inside the sedimentation tank is separated according to height before sedimentation. The sediment generated in the top area of ​​the baffle falls directly onto the baffle. Therefore, the sediment at the higher position does not need to be moved to the bottom of the sedimentation tank to settle, which shortens the sedimentation distance and time and improves the sedimentation efficiency.

[0027] 2. When pouring waste liquid into the collection tank, water is injected into the diversion channel, allowing the water to flow into the collection tank along the inner wall. This cleans the inner wall of the collection tank while the water mixes with the waste liquid, diluting it. The diluted waste liquid has lower viscosity and can pass through the filter screen more easily, preventing the waste liquid from being too viscous and adhering to the filter screen, causing blockage.

[0039] To make the technical means, creative features, and achieved objectives and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0040] To address the shortcomings of existing technologies, such as Figure 1-10 As shown, the present invention provides an integrated waste liquid collection and treatment device, including a filter box 1 for filtering waste liquid and a sedimentation box 6 for settling pollutants in waste liquid, wherein the sedimentation box 6 is provided with a plurality of partitions 601 inside;

[0041] The sedimentation tank 6 has multiple first slots 602 on its inner wall. The first slots 602 are distributed on the inner walls of both sides of the sedimentation tank 6. Two first slots 602 at the same height on the inner walls of both sides of the sedimentation tank 6 are grouped together. The first slots 602 are divided into multiple groups according to their height. The spacing between any two adjacent groups of first slots 602 is the same. The outer ends of the two sides of the partition 601 are respectively inserted into two first slots 602 in one group, thereby installing the partition 601 inside the sedimentation tank 6.

[0042] The partition 601 has a through hole 603 that penetrates the partition 601. The bottom of the partition 601 is provided with a support plate 604. The support plate 604 is located directly below the through hole 603 and its size is larger than that of the through hole 603. Two connecting rods 605 that are connected to the partition 601 are fixedly provided at the top of the support plate 604.

[0043] After adding flocculant, the waste liquid is placed inside the sedimentation tank 6 and left to stand. The flocculant reacts with the harmful substances in the waste liquid, causing them to separate from the waste liquid and produce solid flocs. During the settling process, the flocculent solids in the waste liquid slowly move downwards until they reach the bottom of the sedimentation tank 6. The device has a partition 601 inside the sedimentation tank 6. The partition 601 is detachably installed in the sedimentation tank 6 through the first slot 602. The number and installation height of the partitions 601 can be adjusted according to the amount of waste liquid. After the partitions 601 are installed, they divide the space inside the sedimentation tank 6. However, due to the action of the through hole 603, the top and bottom of the partitions 601 are not completely sealed to each other.

[0044] During the sedimentation process, the sediment in the waste liquid at the top of the baffle 601 will settle to the top of the baffle 601 as it settles downwards. The sediment at the top of the through hole 603 will fall to the top of the corresponding support plate 604 through the through hole 603. Only the sediment generated in the waste liquid in the area between the bottom of the sedimentation tank 6 and the bottommost baffle 601 will settle to the bottom of the sedimentation tank 6. Therefore, by setting the baffle 601, the waste liquid inside the sedimentation tank 6 is separated according to height before sedimentation. The sediment at the higher position does not need to move to the bottom of the sedimentation tank 6 to settle, which shortens the sedimentation distance and time and improves the sedimentation efficiency.

[0045] To facilitate observation of the interior of filter box 1 and sedimentation box 6, such as Figure 1 , 5As shown, both the filter box 1 and the sedimentation box 6 have access doors on their front sides via hinges, and each access door is inlaid with a glass plate.

[0046] The filter box 1 is fixedly provided with a liquid extraction pipe 5 on the side near the sedimentation box 6. A liquid extraction pump 2 is fixedly provided on the liquid extraction pipe 5. One end of the liquid extraction pipe 5 is connected to the sedimentation box 6. A balance pipe with a valve is fixedly provided at the top of the sedimentation box 6.

[0047] The sedimentation tank 6 is fixedly provided with a drain hose 4 with a valve on one side. One end of the drain hose 4 extends into the interior of the sedimentation tank 6 and is fixedly provided with a buoyancy ball 13.

[0048] The interiors of filter box 1 and sedimentation box 6 can be observed through the glass plate embedded in the inspection door, allowing for monitoring of the filtration and sedimentation progress. The suction pipe 5 and suction pump 2 can draw the filtered waste liquid with added flocculant from inside filter box 1 into the filter box 1 for sedimentation. The balance pipe balances the air pressure inside and outside sedimentation box 6. After sedimentation, the clear liquid is discharged through the drain hose 4. The buoyancy ball 13 keeps the drain hose 4 floating in the water during the discharge of clear liquid, preventing it from contacting the sediment and thus avoiding the discharge of sediment.

[0049] Waste liquid is collected using collection box 7, such as Figure 1 , 2 As shown in Figures 6 and 7, a collection box 7 is fixedly provided at the top of the filter box 1, and a sealing plate 8 is provided at the top opening of the collection box 7. A hinge assembly 12 that can be hinged to the collection box 7 is provided on the sealing plate 8.

[0050] The bottom of the collection box 7 is fixed with two inclined blocks 17 that can collect waste liquid. The bottom of the collection box 7 is fixed with a connecting channel 16 extending into the filter box 1. The connecting channel 16 is located between the two inclined blocks 17.

[0051] The filter box 1 is equipped with a filter screen 14 that plays a filtering role. The filter screen 14 is located at the bottom of the connecting channel 16. The inner walls on both sides of the filter box 1 are provided with second slots 21, and the two ends of the filter screen 14 are respectively inserted into the two second slots 21.

[0052] Lift the sealing plate 8 and pour the waste liquid into the collection box 7. Under the action of the inclined block 17, the waste liquid entering the collection box 7 is collected at the connecting channel 16 and discharged into the filter box 1 through the connecting channel 16. After reaching the filter box 1, the waste liquid passes through the filter screen 14, and the filter screen 14 is used to perform preliminary filtration of impurities in the waste liquid.

[0053] The dilution process is controlled by opening and closing the sealing plate 8, such as... Figure 1 , 2As shown in 3, 4, 6, 8, and 9, the hinge assembly 12 includes a bracket 1202 fixedly disposed on the rear side of the collection box 7. The bracket 1202 has a central rod 1207 inside, and both ends of the central rod 1207 are fixedly connected to the inner wall of the bracket 1202.

[0054] The outer end of the central rod 1207 is fitted with a sleeve 1203, and the outer end of the sleeve 1203 is fixedly fitted with a connecting plate 1201 connected to the sealing plate 8. Both ends of the sleeve 1203 are provided with a spring 1204, and both ends of the spring 1204 are fixedly connected to the inner wall of the sleeve 1203 and the bracket 1202, respectively.

[0055] The outer end of the central rod 1207 is inlaid with a first electrode plate 1205, and the inner wall of the sleeve 1203 is fixedly provided with a second electrode plate 1206.

[0056] When the sealing plate 8 is opened, the sealing plate 8 is lifted and drives the connecting plate 1201, which in turn drives the sleeve 1203 to rotate around the central rod 1207. During the rotation of the sleeve 1203, the spring 1204 is driven to tighten and become elastic. At the same time, after the sleeve 1203 rotates, it drives the second electrode plate 1206 to rotate. When the second electrode plate 1206 rotates to a certain angle, it will contact the first electrode plate 1205. When the sealing plate 8 is closed, the connecting plate 1201 and the sleeve 1203 will reverse, the second electrode plate 1206 will separate from the first electrode plate 1205, and the elastic force of the spring 1204 will be released, driving the sleeve 1203 and the connecting plate 1201 to make the sealing plate 8 cover the top of the collection box 7 tightly.

[0057] A diversion channel 18 is fixedly provided on the inner wall of the collection box 7. A water outlet groove 19 is opened at the bottom end of the diversion channel 18 where it contacts the inner wall of the collection box 7, so that the water can flow along the inner wall of the collection box 7. A water guide pipe 11 connected to the diversion channel 18 is fixedly provided on one side of the collection box 7. A solenoid valve electrically connected to the first electrode plate 1205 and the second electrode plate 1206 is fixedly provided on the water guide pipe 11.

[0058] The filter box 1 is provided with a water storage tank 10 on the side away from the sedimentation tank 6. The top of the water storage tank 10 is detachably equipped with a cover plate 20. One end of the water guide pipe 11 passes through the cover plate 20 and extends into the water storage tank 10. The top of the cover plate 20 is fixedly equipped with an air inlet pipe with a valve, which uses air pressure to add water into the collection box 7. The bottom of the sealing plate 8 is fixedly equipped with an ultraviolet lamp electrically connected to the first electrode plate 1205 and the second electrode plate 1206, which plays a role in sterilization and disinfection of the inside of the collection box 7.

[0059] Clean water is stored inside the water storage cylinder 10. During the process of storing water into the water storage cylinder 10, air is injected into the water storage cylinder 10 through the air inflator, so that the air pressure inside the water storage cylinder 10 is higher than that of the external environment. When the sealing plate 8 is closed, the solenoid valve on the water guide pipe 11 is closed. When the sealing plate 8 is opened and the first electrode plate 1205 and the second electrode plate 1206 are in contact, the solenoid valve on the water guide pipe 11 is opened. The air pressure drives the water inside the water storage cylinder 10 to flow into the diversion channel 18 along the water guide pipe 11 and out through the water outlet 19. The outflowing water flows along the inner wall of the collection box 7, which plays the role of cleaning the inner wall of the collection box 7.

[0060] Simultaneously, water enters the collection tank 7 and mixes with the waste liquid during the pouring process, thus diluting the waste liquid. The diluted waste liquid has reduced viscosity, making it easier to pass through the filter screen 14, preventing the waste liquid from being too viscous and adhering to the filter screen 14, causing blockage. At the same time, the first electrode plate 1205 and the second electrode plate 1206 control the ultraviolet lamp. When the sealing plate 8 is closed, the first electrode plate 1205 and the second electrode plate 1206 separate, and the ultraviolet lamp turns on, disinfecting the inside of the collection tank 7. When the sealing plate 8 is open, the first electrode plate 1205 and the second electrode plate 1206 come into contact, causing the ultraviolet lamp to turn off, thus automatically controlling it.

[0061] To ensure the flocculant and waste liquid are mixed evenly, such as Figure 2 , 6 As shown in Figure 10, a flocculant cylinder 9 is provided on the rear side of the collection box 7. A liquid addition pipe with a valve is fixed at the top of the flocculant cylinder 9. Two insertion pipes 15 with valves are fixed at the bottom of the flocculant cylinder 9. One end of the insertion pipe 15 extends into the filter box 1. Multiple shower heads 3 are fixed on the insertion pipe 15. The shower heads 3 are located on the top of the filter screen 14 and are higher than the bottom of the connecting channel 16, so as to add flocculant into the waste liquid.

[0062] Liquid flocculant is stored inside the flocculant cylinder 9. When adding flocculant, air is also injected into the flocculant cylinder 9 to maintain high pressure inside the flocculant cylinder 9. After the waste liquid is filtered, the solenoid valve on the insertion tube 15 is opened. Under the action of air pressure, the flocculant flows into the filter box 1 along the insertion tube 15 and is sprayed out through the shower head 3. The shower head 3 can make the flocculant fall into the filter box 1 as a dispersed water flow so that the flocculant and waste liquid are mixed more evenly. The amount of flocculant added is according to the amount of waste liquid.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
