Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated production wastewater treatment device. Background Technology
[0002] Industrial wastewater refers to liquid waste containing various pollutants generated during various production processes such as industrial production, agricultural production, and commercial activities. Its composition and properties vary depending on the production industry, process, and raw materials. If discharged directly without effective treatment, it will pollute the ecological environment such as surface water, soil, and groundwater, affect the ecological balance, damage the natural landscape, and may also endanger human health. Therefore, it is necessary to use appropriate physical, chemical, and biological treatment methods according to its characteristics to achieve standard discharge or recycling.
[0003] When treating industrial wastewater, the first step is usually filtration. Filtration can effectively remove suspended solid particles from the wastewater, including large impurities, silt, fibers, and other insoluble substances, to prevent clogging and wear in subsequent treatment processes, which would affect the treatment effect and the normal operation of the equipment, thereby improving the efficiency and stability of the entire wastewater treatment system.
[0004] Commercially available wastewater filtration devices primarily use filter baskets to filter particulate matter. Water passes through the filter holes, while the contaminants remain inside the basket. However, when the contaminants accumulate in the filter basket to a certain extent, the basket is usually removed from the filtration equipment for cleaning. This process of disassembling and assembling the filter basket is time-consuming and labor-intensive, and frequent disassembly and assembly can damage the basket and its connecting parts to the main body of the equipment, thus affecting the lifespan of the device. Utility Model Content
[0005] The purpose of this invention is to provide an integrated production wastewater treatment device that effectively solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution.
[0007] An integrated production wastewater treatment device includes an outer tank, a bottom cylinder fixed to the bottom of the outer tank, the bottom end of the bottom cylinder extending through to the bottom of the outer tank, a drain port for discharging filtered dirt on the bottom end of the bottom cylinder, a vertically extending filter cylinder fixed to the top of the bottom cylinder, a top cover fixed to the top of the filter cylinder, a sewage inlet pipe for introducing production wastewater into the filter cylinder on the top cover, and a drain port located on one side of the bottom cylinder at the bottom of the outer tank.
[0008] Furthermore, a drain valve is installed inside the drain outlet, and a drain valve is installed inside the drain outlet.
[0009] Furthermore, the drain outlet is coaxially arranged with the bottom cylinder, and the inner diameter of the drain outlet is smaller than the inner diameter of the bottom cylinder. A disc is installed inside the bottom cylinder, which is located directly above the drain outlet, and the outer diameter of the disc is smaller than the inner diameter of the drain outlet. Several arc-shaped guide plates are fixed in an array on the outer peripheral wall of the disc, and each arc-shaped guide plate slides against the inner bottom wall of the bottom cylinder. A drive mechanism is provided on the outer tank body to drive the disc to rotate.
[0010] Furthermore, the outer tank is equipped with a backwashing mechanism to rinse the filter holes on the filter cartridge from the outside in.
[0011] Furthermore, the backwashing mechanism includes an annular pipe, vertical pipes, nozzles, and a flushing water inlet pipe. The annular pipe is fixed to the top of the outer tank and surrounds the filter cartridge. Several vertical pipes, all extending vertically downwards, are arranged in a circular array around the filter cartridge on the annular pipe. Several nozzles are arranged at intervals from top to bottom on each vertical pipe, and each nozzle extends toward the axis of the filter cartridge. One end of the flushing water inlet pipe is connected to the cleaning water supply equipment, and the other end extends through the outer tank and connects to the annular pipe.
[0012] Furthermore, the height of the top end face of the bottom cylinder is higher than the height of the bottom wall inside the outer tank.
[0013] Furthermore, the drive mechanism includes a mounting bracket, a drive motor, and a shaft. The inverted L-shaped mounting bracket is fixed to the side of the outer tank, the drive motor is fixed to the cantilever of the mounting bracket, one end of the shaft is fixed to the output shaft of the drive motor, and the other end extends through the top cover into the filter cartridge and is fixed to the top of the disc.
[0014] Furthermore, the ends of each arc-shaped guide plate furthest from the disc slide against the inner edge of the bottom cylinder.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.
[0016] This utility model integrates the outer tank, filter cartridge, and bottom cylinder into one design. By setting a special drain port at the bottom of the bottom cylinder for sewage discharge, when the sewage accumulates in the filter cartridge to a certain amount, the sewage can be discharged by adjusting and opening the drain valve, thus eliminating the need to remove the filter cartridge for internal cleaning.
[0017] This invention, by setting the top end face of the bottom cylinder higher than the bottom wall of the outer tank, allows for the continued supply of water through the sewage inlet pipe after the dirt in the filter cartridge is discharged through the drain port. Since the drain valve is closed and the top of the bottom cylinder is higher than the bottom wall of the outer tank, water will accumulate in the outer tank and the liquid level will gradually rise. When the liquid level is higher than the bottom cylinder, the water will flow back into the bottom cylinder, while the drain valve is open, allowing the water entering the bottom cylinder to be discharged through the drain port, thus flushing out the dirt retained in the bottom cylinder and improving the cleaning effect on the filter cartridge and the bottom cylinder.
[0018] This invention uses a drive motor to operate, whose output shaft drives the shaft to rotate. The rotating shaft drives the disc and the arc-shaped guide plate to rotate. Because the arc-shaped guide plate extends in an arc shape, as it rotates, it can push the dirt upwards towards the drain outlet, ultimately causing the dirt to fall into the drain outlet and be discharged. This avoids dirt residue on the bottom wall of the bottom cylinder and further improves the cleaning effect.
[0019] This invention delivers cleaning water to a ring pipe via a flushing water inlet pipe, which then distributes the water to various vertical pipes. Finally, the water is sprayed out through each nozzle toward the axis of the filter cartridge, which can flush out the dirt accumulated and blocked in the filter holes of the filter cartridge and let it fall into the drain port, thus preventing the filter holes of the filter cartridge from becoming clogged due to excessive dirt accumulation and affecting the filtration effect.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0028] Example 1
[0029] The integrated production wastewater treatment device includes an outer tank 1, which is made of 304 stainless steel with a thickness of 3-5mm. A bottom cylinder 3 is fixed inside the bottom of the outer tank 1. The bottom end of the bottom cylinder 3 extends through to the bottom of the outer tank 1. A drain port 31 is provided on the bottom end of the bottom cylinder 3 for discharging the filtered dirt. The drain port 31 has a narrowing angle of 15°-30° to ensure that the dirt slides down smoothly.
[0030] A drain valve 32 is installed inside the drain outlet 31. A vertically extending filter cylinder 2 is fixed on the top of the bottom cylinder 3. A top cover 21 is fixed on the top of the filter cylinder 2. A sewage inlet pipe 22 for introducing production wastewater into the filter cylinder 2 is provided on the top cover 21. A drain outlet 11 is provided at the bottom of the outer tank 1 on one side of the bottom cylinder 3. A drain valve 12 is installed inside the drain outlet 11.
[0031] When using this treatment device to filter production wastewater, the drain valve 32 is closed and the drain valve 12 is open. The production wastewater is transported to the filter cartridge 2 through the sewage inlet pipe 22. The water enters the outer tank 1 located outside the filter cartridge 2 through the filter holes on the filter cartridge 2 and is finally discharged through the drain outlet 11. Particulate matter and other pollutants are filtered out in the filter cartridge 2 and accumulate, thus achieving the primary filtration treatment process of the production wastewater.
[0032] When the amount of dirt filtered out in the top cover 21 accumulates to a certain level, it is necessary to clean the dirt in the filter cartridge 2. First, stop the water supply by adjusting the sewage inlet pipe 22, adjust the drain valve 12 to the closed state, and at the same time adjust the drain valve 32 to the open state. The dirt accumulated in the filter cartridge 2 is discharged through the drain port 31 and the drain valve 32, thereby cleaning the dirt in the filter cartridge 2.
[0033] The top end face of the bottom cylinder 3 is higher than the inner bottom wall of the outer tank 1, with a specific height difference of 60-100mm. After the dirt in the filter cartridge 2 is discharged through the drain port 31, the sewage inlet pipe 22 continues to supply water. Since the drain valve 12 is closed, and the top of the bottom cylinder 3 is higher than the inner bottom wall of the outer tank 1, the water in the outer tank 1 will accumulate and the liquid level will gradually rise. When the liquid level is higher than the bottom cylinder 3, the water will flow back into the bottom cylinder 3. The drain valve 32 is open, and the water entering the bottom cylinder 3 can be discharged through the drain port 31, flushing out the dirt retained in the bottom cylinder 3 and improving the cleaning effect on the filter cartridge 2 and the bottom cylinder 3.
[0034] As can be seen, this device integrates the outer tank 1, filter cartridge 2 and bottom cylinder 3 into one unit. By setting a drain port 31 at the bottom of the bottom cylinder 3 for sewage discharge, when the sewage in the filter cartridge 2 accumulates to a certain amount, the sewage can be discharged by adjusting and opening the drain valve 32, thus eliminating the need to remove the filter cartridge 2 for cleaning.
[0035] Example 2
[0036] Please see Figures 1-4 The difference between this embodiment and Embodiment 1 is that:
[0037] The drain outlet 31 is coaxially arranged with the bottom cylinder 3, and the inner diameter of the drain outlet 31 is smaller than the inner diameter of the bottom cylinder 3.
[0038] The bottom cylinder 3 is equipped with a disc 4, which is located directly above the drain outlet 31. The outer diameter of the disc 4 is smaller than the inner diameter of the drain outlet 31. Several arc-shaped guide plates 41 are fixed in an array on the outer peripheral wall of the disc 4. Each arc-shaped guide plate 41 slides and fits against the inner bottom wall of the bottom cylinder 3. The outer tank 1 is equipped with a drive mechanism 5, which is used to drive the disc 4 to rotate.
[0039] The drive mechanism 5 includes a mounting bracket 51, a drive motor 52, and a shaft 53. The inverted L-shaped mounting bracket 51 is fixed to the side of the outer tank 1. The drive motor 52 is fixed to the cantilever 511 of the mounting bracket 51. One end of the shaft 53 is fixed to the output shaft of the drive motor 52, and the other end extends through the top cover 21 into the filter cartridge 2 and is fixed to the top of the disc 4. The drive motor 52 is a geared motor with a power of 0.5-1.5kW and a speed of 10-30rpm.
[0040] The ends of each arc-shaped guide plate 41 that are away from the disc 4 slide against the inner edge wall of the bottom cylinder 3.
[0041] The drive motor 52 operates, and its output shaft drives the shaft 53 to rotate. The rotating shaft 53 drives the disc 4 and the arc-shaped guide plate 41 to rotate. As the arc-shaped guide plate 41 extends in an arc shape, it can push the dirt upwards towards the drain outlet 31 as it rotates, ultimately causing the dirt to fall into the drain outlet 31 and be discharged, thus avoiding dirt residue on the bottom wall of the bottom cylinder 3 and further improving the cleaning effect.
[0042] In addition, the bottom of the arc-shaped guide plate 41 slides against the inner wall surface of the bottom cylinder 3, and the end of the arc-shaped guide plate 41 slides against the inner edge wall of the bottom cylinder 3, so as to avoid excessive gaps between the arc-shaped guide plate 41 and the inner wall of the bottom cylinder 3, thereby improving the capture effect of dirt.
[0043] Example 3
[0044] Please see Figure 2 and Figure 4 The difference between this embodiment and Embodiment Two is that:
[0045] The outer tank 1 is also equipped with a backwashing cleaning mechanism, which is used to rinse the filter holes on the filter cartridge 2 from the outside to the inside.
[0046] Specifically, the backwashing mechanism includes an annular pipe 6, vertical pipes 61, nozzles 62, and a flushing water inlet pipe 63. The annular pipe 6 is fixed to the top of the outer tank 1 and is arranged around the filter cartridge 2. Several vertical pipes 61 are arranged in a circular array around the filter cartridge 2, all extending vertically downwards. Several nozzles 62 are arranged at intervals from top to bottom on each vertical pipe 61. Each nozzle 62 extends towards the axis of the filter cartridge 2. One end of the flushing water inlet pipe 63 is connected to the cleaning water supply equipment, and the other end extends through the outer tank 1 and connects to the annular pipe 6.
[0047] Specifically, the six vertical pipes 61 are arranged at 60° intervals around the circumference of the annular pipe 6.
[0048] When cleaning the inside of the filter cartridge 2, the cleaning water is delivered to the annular pipe 6 through the flushing water inlet pipe 63, and then distributed to each vertical pipe 61 through the annular pipe 6. Finally, it is sprayed out towards the axis of the filter cartridge 2 through each nozzle 62. This can flush out the dirt accumulated and blocked in the filter holes of the filter cartridge 2 and make it fall into the drain port 31, thus avoiding the filter holes of the filter cartridge 2 from being blocked due to excessive dirt accumulation, which would affect the filtration effect.
[0049] During backwashing, the flow rate of a single vertical pipe 61 is guaranteed to be 0.3-0.6 m³ / h, and the spray speed of the nozzle 62 is 15-25 m / s to effectively remove filter blockages.
[0050] In addition, several vertical pipes 61 are arranged in a ring around the filter cylinder 2, and several nozzles 62 are arranged on each vertical pipe 61 from top to bottom, so that the spray range of the nozzles 62 complements each other, so as to ensure that the backwash water covers the outer periphery of the filter cylinder 2 as much as possible, and improves the backwash cleaning effect on the filter holes on the filter cylinder 2.
[0051] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. Furthermore, the specific structure, model and coefficient index of all its components are its own technology. As long as it can achieve its beneficial effect, it can be implemented. Therefore, it will not be described in detail.
[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
