A wastewater circulation filtration reaction device

Abstract

This utility model discloses a wastewater circulation filtration reaction device, relating to the field of wastewater treatment technology. It includes an interception cylinder, with a reaction tank fixedly connected to the top of the interception cylinder and support legs fixedly installed at the bottom. A filter barrel is rotatably connected within the support legs. By opening a first valve, wastewater can circulate through a circulation outlet mechanism into the reaction tank. Combined with the filter holes to intercept pollutants, the wastewater can be repeatedly circulated and purified, achieving a thorough purification effect. Secondly, by switching the drive mechanism, the filter barrel and partitions are driven to rotate, moving the impurities intercepted by the filter holes to a side away from the reaction tank. Simultaneously, the unblocked filter holes and partitions are aligned with the reaction tank, allowing for continued wastewater filtration and purification. When the filter holes are vertically downwards, due to gravity, some of the intercepted impurities can automatically fall from the bottom of the interception cylinder. Using this structure, the intercepted impurities can be discharged and treated without disassembling the filter barrel, improving the efficiency of wastewater treatment.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater circulation filtration reaction device. Background Technology

[0002] In the wastewater treatment process, one of the treatment methods is to add chemicals to the wastewater so that the chemicals react with the pollutants in the wastewater, transforming pollutants that are difficult to filter and purify directly into forms that are easily intercepted (such as sediments and flocs), and then using filtration to separate the pollutants.

[0003] However, existing wastewater treatment devices typically only perform a single filtration after the wastewater reacts with the chemicals, which is insufficient to fully react with and intercept pollutants in the wastewater. Furthermore, after a period of use, the filter screen becomes clogged with a large amount of pollutants, affecting the wastewater treatment efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a sewage circulation filtration reaction device to solve the problems that it is difficult to fully react and intercept pollutants in sewage after a single filtration, and that the filter screen will become clogged with a lot of pollutants after a period of use, which affects the sewage treatment efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sewage circulation filtration reaction device, including an intercepting cylindrical barrel, a reaction chamber fixedly connected to the top of the intercepting cylindrical barrel, a support foot fixedly installed at the bottom of the intercepting cylindrical barrel, a filter barrel rotatably connected inside the support foot, a switching drive mechanism capable of driving the filter barrel to rotate provided on the outer side of the intercepting cylindrical barrel, filter holes evenly distributed on the filter barrel, multiple partitions evenly arranged on the outer side of the filter barrel, and the side of the partition away from the filter barrel can fit against the inner wall of the intercepting cylindrical barrel, a plugging pipe fixedly installed inside the intercepting cylindrical barrel, the filter barrel movably sleeved on the outer surface of the plugging pipe, a filter outlet opened at the top of the plugging pipe, a circulation outlet mechanism provided on the outer side of the intercepting cylindrical barrel and the reaction chamber, a partition plate fixedly installed inside the reaction chamber, a circular pipe fixedly connected to the middle of the partition plate, and a first valve provided on the circular pipe.

[0006] Preferably, the maximum spacing between two adjacent partitions is equal to the width of the reaction chamber, and the minimum spacing is equal to the width of the filter outlet. The partition plate is an arc-shaped structure with the opening facing upwards.

[0007] Preferably, the switching drive mechanism includes a first motor, which is fixedly installed on the outside of the intercepting cylinder. The output end of the first motor is connected to a first bevel gear, and one end of the filter barrel passes through the intercepting cylinder and is fixedly connected to a second bevel gear. The first bevel gear meshes with the second bevel gear.

[0008] Preferably, the circulating water outlet mechanism includes a liquid pump, which is fixedly installed on the outside of the intercepting cylinder. The input end of the liquid pump is connected to one end of the plug pipe, and the output end of the liquid pump is fixedly connected to a three-way pipe, which is fixedly mounted on the intercepting cylinder. A second valve capable of switching the direction of sewage transport is provided on the three-way pipe. One output end of the three-way pipe is fixedly connected to a circulation pipe, and the other output end is fixedly connected to a water outlet pipe. The end of the circulation pipe away from the three-way pipe is fixedly connected to the reaction tank.

[0009] Preferably, the reaction chamber is provided with a stirring mechanism located above the partition plate. The stirring mechanism includes a second motor, which is fixedly installed on the outside of the reaction chamber. A stirring shaft is rotatably connected inside the reaction chamber, and the output end of the second motor is connected to one end of the stirring shaft. Several stirring rods are evenly distributed on the stirring shaft.

[0010] Preferably, the bottom of the intercepting cylinder is provided with a sewage discharge mechanism, which includes a sewage discharge frame. The sewage discharge frame is fixedly connected to the bottom of the intercepting cylinder. Two conveyor wheels are horizontally rotatably connected inside the sewage discharge frame. A conveyor belt is fitted on the two conveyor wheels. A third motor is fixedly installed on the sewage discharge frame. The output end of the third motor is connected to the end of one of the conveyor wheels.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention allows wastewater to circulate through a circulating outlet mechanism into the reaction tank by opening the first valve. Combined with filter holes to intercept pollutants, the wastewater can be repeatedly circulated for thorough purification. Secondly, by switching the drive mechanism, the filter barrel and baffles rotate, moving the impurities intercepted by the filter holes to a side away from the reaction tank. Simultaneously, the unblocked filter holes and baffles align with the reaction tank, allowing for continued wastewater filtration. When the filter holes are vertically downwards, if a large amount of impurities are intercepted, gravity will cause some of the intercepted impurities to fall automatically from the bottom of the interception barrel, effectively preventing complete blockage of the filter holes. Using this structure, the intercepted impurities can be discharged and treated without disassembling the filter barrel, improving wastewater treatment efficiency.

[0013] This invention uses a second motor to drive a stirring shaft and stirring rod to stir the wastewater, thereby improving the reaction efficiency between the wastewater and the reagent.

[0014] This invention uses a third motor to drive the conveyor wheel to rotate, which allows the conveyor belt to transport and collect contaminants to one side, making it easier to process the contaminants. Attached Figure Description

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 This utility model provides a wastewater circulation filtration reaction device, including an intercepting cylindrical barrel 1. A reaction chamber 2 is fixedly connected to the top of the intercepting cylindrical barrel 1. A support leg 3 is fixedly installed at the bottom of the intercepting cylindrical barrel 1. A filter barrel 4 is rotatably connected inside the support leg 3. A switching drive mechanism 5 capable of driving the filter barrel 4 to rotate is provided on the outer side of the intercepting cylindrical barrel 1. Filter holes 6 are evenly distributed on the filter barrel 4. Multiple partitions 7 are arrayed at equal intervals on the outer side of the filter barrel 4, and the side of the partitions 7 away from the filter barrel 4 can fit against the inner wall of the intercepting cylindrical barrel 1. A filter chamber 2 is also fixed inside the intercepting cylindrical barrel 1. A plug pipe 14 is installed, and a filter bucket 4 is movably fitted onto the outer surface of the plug pipe 14. A filter port 15 is opened at the top of the plug pipe 14. A circulating water outlet mechanism 8 is provided on the outside of the intercepting cylindrical barrel 1 and the reaction tank 2. A partition plate 11 is fixedly installed inside the reaction tank 2. A cylindrical pipe 12 is fixedly connected to the middle of the partition plate 11. A first valve 13 is provided on the cylindrical pipe 12. The maximum distance between two adjacent partition plates 7 is equal to the width of the reaction tank 2, and the minimum distance is equal to the width of the filter port 15. The partition plate 11 is an arc-shaped structure with the opening facing upward.

[0023] Among them, a partition channel can be formed between two adjacent partitions 7. The filter holes 6 are used to intercept pollutants and impurities after the reaction of the filter agents in the wastewater. The plug 14 is used to seal some of the filter holes 6. When the filter bucket 4 rotates, the partitions 7 only drive the intercepted material to rotate, reducing the amount of wastewater in the pollutants and impurities.

[0024] Specifically, after the wastewater reacts with the reagent in the reaction tank 2, the first valve 13 is opened, allowing the wastewater to pass sequentially through the circular pipe 12, the partition channel, the filter hole 6, the filter outlet 15, and the plug 14. It is then circulated back into the reaction tank 2 by the circulating water outlet mechanism 8, undergoing multiple cycles to purify the wastewater and achieve thorough purification. When the filter hole 6 above the filter outlet 15 has intercepted a significant amount of pollutants, the first valve 13 is closed. The circulating water outlet mechanism 8 then circulates the water in the partition channel between the baffles 7 back into the reaction tank 2. The switching drive mechanism 5 then drives the filter bucket 4 and the baffles 7 to rotate, moving the impurities intercepted by the filter hole 6 away from the reaction tank 2. Simultaneously, the unblocked filter holes 6 and baffles 7 are aligned with the reaction tank 2, allowing for continued wastewater filtration and purification. When the filter hole 6 is vertically downwards, if a large amount of impurities are intercepted, gravity will cause some of the intercepted impurities to fall automatically from the bottom of the interception cylinder 1, effectively preventing the filter hole 6 from becoming completely blocked. Using this structure, the intercepted impurities can be discharged and treated without disassembling the filter bucket 4, improving the efficiency of wastewater treatment.

[0025] Preferably, the switching drive mechanism 5 includes a first motor 51, which is fixedly installed on the outside of the intercepting cylinder 1. The output end of the first motor 51 is connected to a first bevel gear 52. One end of the filter barrel 4 passes through the intercepting cylinder 1 and is fixedly connected to a second bevel gear 53. The first bevel gear 52 and the second bevel gear 53 mesh with each other.

[0026] Specifically, by driving the first bevel gear 52 to mesh with the second bevel gear 53 through the first motor 51, the filter barrel 4 can be rotated to switch the partition 7.

[0027] Preferably, the circulating water outlet mechanism 8 includes a liquid pump 81, which is fixedly installed on the outside of the intercepting cylinder 1. The input end of the liquid pump 81 is connected to one end of the plug pipe 14, and the output end of the liquid pump 81 is fixedly connected to a three-way pipe 82. The three-way pipe 82 is fixedly installed on the intercepting cylinder 1. A second valve 83 capable of switching the sewage conveying direction is provided on the three-way pipe 82. One output end of the three-way pipe 82 is fixedly connected to a circulation pipe 84, and the other output end is fixedly connected to a water outlet pipe 85. The end of the circulation pipe 84 away from the three-way pipe 82 is fixedly connected to the reaction tank 2.

[0028] The second valve 83 is a valve for switching existing three-way pipes, which will not be described in detail. The sewage can be drawn out from the blockage pipe 14 by the liquid pump 81 and circulated into the reaction tank 2 through the three-way pipe 82 and the circulation pipe 84 in sequence for multiple filtrations, or the purified sewage can be transported to the next process through the three-way pipe 82 and the outlet pipe 85 in sequence.

[0029] Furthermore, the reaction chamber 2 is equipped with a stirring mechanism 9 located above the partition plate 11. The stirring mechanism 9 includes a second motor 91, which is fixedly installed on the outside of the reaction chamber 2. A stirring shaft 92 is rotatably connected inside the reaction chamber 2, and the output end of the second motor 91 is connected to one end of the stirring shaft 92. Several stirring rods 93 are evenly distributed on the stirring shaft 92.

[0030] Specifically, during the reaction between wastewater and chemicals, the stirring shaft 92 and stirring rod 93 can be driven by the second motor 91 to stir the wastewater and chemicals, thereby improving the reaction efficiency.

[0031] Preferably, a sewage discharge mechanism 10 is provided at the bottom of the intercepting cylinder 1. The sewage discharge mechanism 10 includes a sewage discharge frame 101, which is fixedly connected to the bottom of the intercepting cylinder 1. Two conveyor wheels 102 are horizontally rotatably connected inside the sewage discharge frame 101. A conveyor belt 103 is fitted on the two conveyor wheels 102. A third motor 104 is fixedly installed on the sewage discharge frame 101. The output end of the third motor 104 is connected to the end of one of the conveyor wheels 102.

[0032] Specifically, the intercepted impurities fall from the interception cylinder 1 onto the conveyor belt 103. The third motor 104 drives the conveyor wheel 102 to rotate, which allows the conveyor belt 103 to transport and gather the contaminated impurities to one side, making it easier to process the contaminated impurities.
