Description

Technical Field

[0001] This utility model relates to the technical field of wastewater filtration environmental protection equipment, and in particular to a circulating water supply wastewater filtration environmental protection equipment. Background Technology

[0002] In some large factories, especially in energy-intensive industries such as chemical, power, and metallurgy, large amounts of circulating water are needed to cool high-temperature equipment during production to ensure stable operation and prevent overheating damage. However, during long-term circulation, the circulating water is prone to gradual deterioration due to the presence of rust products (such as iron oxide particles) from pipes, metal debris from equipment wear, dust settling from the air, and microbial growth. These impurities not only reduce the water's thermal conductivity and affect cooling performance but can also clog pipes, corrode equipment, and even shorten the lifespan of critical components. Therefore, to ensure the stability and energy efficiency of the circulating water system, it is essential to use high-efficiency filtration and environmental protection equipment to purify wastewater in real time, removing suspended solids, sediments, and other pollutants to maintain water cleanliness and ensure the long-term efficient operation of the cooling system.

[0003] Based on this, the applicant disclosed a circulating water supply wastewater filtration environmental protection device in patent publication number CN211367179U, including a filter bucket, a base, and a housing. A baffle plate is welded to the top of the base, and the filter bucket is threadedly connected to the outer side of the top of the base. The housing is bolted to the top of the filter bucket, and infrared heating lamps are bolted to both sides inside the housing. An electric hydraulic cylinder is bolted to the top of the housing via a mounting bracket, and a frame is bolted to the bottom output shaft of the electric hydraulic cylinder. A first filter screen is bolted to the inside of the frame, and a second filter screen is bolted to one side of the first filter screen. This utility model, by setting up a stainless steel filter screen, a first filter screen, and a second filter screen, can effectively filter wastewater and also has a heating function, which can improve the service life of the first and second filter screens, making it suitable for widespread promotion and use.

[0004] However, after long-term use, the applicant found that although this circulating water supply wastewater filtration environmental protection equipment can effectively filter wastewater by setting up stainless steel filter screens, filter plate number one, and filter plate number two, and the heating function can extend the service life of filter plate number one and filter plate number two, the stainless steel filter screens are prone to clogging after long-term use. This requires manual disassembly and cleaning by staff, which is cumbersome, time-consuming, and labor-intensive, reducing maintenance efficiency. Furthermore, when using chemicals (such as corrosion inhibitors, scale inhibitors, or bactericides) to treat circulating water, relying solely on the natural diffusion of the water flow can lead to insufficient contact between the chemicals and the circulating water. This not only reduces the utilization rate of the chemicals but also makes it difficult to ensure the mixing effect between the chemicals and the circulating water, affecting the filtration effect. Therefore, the applicant is making further improvements and optimizations to this circulating water supply wastewater filtration environmental protection equipment. Utility Model Content

[0028] Example 1: This utility model proposes an environmental protection device for circulating water supply and sewage filtration.

[0029] In one embodiment of this utility model, a circulating water supply sewage filtration environmental protection device includes a base 1, a box 2 and a box cover 3, and also includes a filter screen plate 4, a scraper 5, a stirring assembly 6, a filtering assembly 7 and a decontamination assembly 8. A partition 9 is provided inside the box 2, which divides the inner cavity of the box 2 into a connected filtering chamber 10 and a clean water chamber 11. A water inlet pipe 12 is provided on the outer wall of the filtering chamber 10. The stirring assembly 6 and the filter screen plate 4 are both provided in the filtering chamber 10 and are used to stir the circulating water and filter out impurities, respectively. The scraper 5 is connected to the stirring assembly 6 and is used to push and scrape the filter screen plate 4. A sewage pipe 17 is provided at the bottom of the filtering chamber 10. A water outlet pipe 13 is provided at the bottom of the water purification chamber 11. The decontamination component 8 is provided on the cover 3 and is used to clean impurities on the filter component 7. The filter component 7 is movably installed in the water purification chamber 11 and can extend into or out of the decontamination component 8.

[0030] Working Principle: This utility model discloses a circulating water supply and wastewater filtration environmental protection device. Circulating water is transported to the filter chamber 10 within the housing 2 via the inlet pipe 12. The stirring component 6 within the filter chamber 10 agitates the circulating water, and operators can add chemicals and other purification materials, allowing the stirring component 6 to thoroughly mix the chemicals and circulating water to improve filtration efficiency. Simultaneously, the stirring component 6 drives the scraper 5 to automatically clean the accumulated impurities on the filter screen 4, improving maintenance efficiency. Furthermore, after primary filtration by the filter screen 4, the circulating water flows into the purified water chamber 11. Here, the filter component 7 within the purified water chamber 11 performs secondary filtration, and the fully filtered circulating water can flow out through the outlet pipe 13 for reuse.

[0031] Specifically, such as Figures 1 to 5 As shown, in this utility model of a circulating water supply wastewater filtration environmental protection device, by setting the tank 2 on the base 1, the tank 2 can be stably installed in the preset position through the base 1, and the tank 2 can hold circulating water. The circulating water is filtered and purified by the filter screen plate 4, scraper 5, stirring assembly 6 and filter assembly 7 inside the tank 2. During the filtration process, the tank 2 can be sealed by the tank cover 3 to prevent external dust or impurities from falling into the tank 2 and affecting the filtration effect.

[0032] Furthermore, since a partition 9 is installed inside the housing 2, the inner cavity of the housing 2 can be divided into a filtration chamber 10 and a purified water chamber 11. An inlet pipe 12 is installed on the outer wall of the filtration chamber 10, allowing operators to connect the inlet pipe 12 to an external circulating water system, enabling circulating water to flow into the filtration chamber 10. A branch pipe can also be installed at the inlet pipe 12 for adding chemicals (such as corrosion inhibitors, scale inhibitors, or bactericides) and other related purification materials. When the chemicals and circulating water flow into the filtration chamber 10, the stirring component 6 inside the filtration chamber 10 operates to mechanically force-stir, ensuring thorough and uniform mixing of the chemicals and circulating water. This significantly improves the dispersion efficiency and reactivity of the chemicals, ensuring uniform distribution of the chemicals in the circulating water, and preventing excessively high local concentrations or sedimentation, thus guaranteeing the filtration and purification effect on the circulating water and ensuring reliable operation. Furthermore, since a filter screen plate 4 is also installed inside the filter chamber 10, when the stirring assembly 6 is running, the stirring assembly 6 can increase the flow of circulating water, allowing the circulating water to quickly pass through the filter screen plate 4 to filter out impurities in the circulating water, thereby improving filtration efficiency and achieving primary filtration of the circulating water. The structural design is simple and reasonable. Understandably, since the scraper 5 is connected to the stirring assembly 6 by transmission, when it is necessary to clean impurities on the filter screen plate 4, the stirring assembly 6 runs and can simultaneously drive the scraper 5 to push and scrape the impurities accumulated on the filter screen plate 4, thereby realizing automatic cleaning of the filter screen plate 4. There is no need for personnel to manually disassemble and install the filter screen plate 4, simplifying the cleaning operation steps of the filter screen plate 4, saving time and effort, and improving maintenance efficiency and work efficiency. It is worth noting that when cleaning and maintaining the filter screen plate 4, the filter chamber 10 is not filled with circulating water to prevent impurities pushed off the filter screen plate 4 from re-entering and contaminating the circulating water. The impurities can be discharged through the drain pipe 17 located at the bottom of the filter chamber 10, thereby ensuring the cleanliness of the filter chamber 10 and guaranteeing the subsequent filtration and purification effect on the circulating water, making it reliable in use.

[0033] Understandably, after the circulating water undergoes primary filtration through the filter screen 4, it flows into the purified water chamber 11. The purified water chamber 11 contains a filter assembly 7, which can be made of ceramic honeycomb mesh and activated carbon. This filter assembly 7 removes fine impurities from the circulating water, thus achieving secondary filtration. The design is simple and reasonable. After secondary filtration, the circulating water flows out from the outlet pipe 13 at the bottom of the purified water chamber 11 to the external circulating water system for reuse. Furthermore, when it is necessary to clean impurities from the filter assembly 7, the operator inserts it into the cleaning assembly 8. The cleaning assembly 8 can be a sleeve equipped with a heating element 22 or a high-pressure nozzle. This allows the high temperature of the cleaning assembly 8 to melt the fine impurities on the filter assembly 7, or the powerful water jet generated by the high-pressure nozzle to flush the filter micropores, thereby achieving efficient cleaning of the filter assembly 7 and restoring its filtration capacity, improving maintenance efficiency.

[0034] It should be noted that a control system is also installed on the side wall of the housing 2, which is communicatively connected to the stirring assembly 6 and the cleaning assembly 8. This facilitates the operation and start / stop of the stirring assembly 6 and the cleaning assembly 8 by the staff, making the operation simple and convenient. The control system is a mature existing technology and will not be described in detail here.

[0035] In one embodiment, the stirring assembly 6 includes a first driving member 14, a rotating shaft 15, and a plurality of stirring blades 16. The first driving member 14 is detachably mounted on the side wall of the housing 2. The power output end of the first driving member 14 extends into the filter chamber 10 and is detachably connected to the rotating shaft 15. A plurality of stirring blades 16 are spaced apart on the rotating shaft 15 along its extending direction. Specifically, as shown... Figures 1 to 3 As shown, the first driving component 14 can be a motor as in the prior art. By detachably connecting the rotating shaft 15 to the power output end of the first driving component 14 (such as through a threaded connection), the rotating shaft 15 and the several stirring blades 16 on the rotating shaft 15 can rotate relative to the housing 2 under the action of the first driving component 14 to stir the reagent and circulating water, ensuring that the reagent and circulating water can be fully and evenly mixed. It should be noted that the first driving component 14 can be detachably installed on the side wall of the housing 2 by means of bolt connection, which facilitates the disassembly and assembly of the first driving component 14 by the operator and is conducive to maintenance.

[0036] In one embodiment, a scraper 5 is provided at the end of the rotating shaft 15 away from the first driving member 14, which abuts against the filter screen plate 4. A collection groove is provided at the bottom of the filter chamber 10 corresponding to the position of the scraper 5, and the collection groove is connected to the drain pipe 17. Specifically, as shown... Figures 1 to 3As shown, by setting the scraper 5 at the end of the rotating shaft 15 away from the first driving member 14, the scraper 5 can abut against the filter screen plate 4 and rotate relative to the filter screen plate 4 under the action of the first driving member 14, so as to push and scrape the impurities accumulated on the filter screen plate 4, thereby realizing the automatic cleaning operation of the filter screen plate 4 without the need for manual cleaning by the staff, which is convenient to use and improves maintenance efficiency. At the same time, after the scraper 5 scrapes off the impurities on the filter screen plate 4, the impurities fall into the collection tank. Since the collection tank is connected to the drain pipe 17, the impurities can flow into the drain pipe 17 along the collection tank and be discharged to the outside of the box 2 through the drain pipe 17, ensuring the cleaning effect of impurities and preventing impurities from falling from the filter screen plate 4 and accumulating in the filter chamber 10. It should be noted that the bottom of the collection tank slopes downwards towards the drain pipe 17, meaning that the bottom of the collection tank forms a slope, and the bottom of the slope is flush with the drain pipe 17. This effectively improves the flowability of impurities and facilitates their discharge. The structural design is ingenious and reasonable.

[0037] In one embodiment, a storage box 18 is movably installed at the bottom of the housing 2. The storage box 18 is spaced apart from the drain pipe 17, and a handle is provided on the storage box 18. Specifically, as shown... Figure 1 and Figure 2 As shown, staff can place medicines or other utensils in the storage box 18 for easy access and use, thus improving work efficiency. At the same time, the handle makes it easy for staff to pull out the storage box 18 to retrieve and put in items, making it convenient to operate and use.

[0038] In one embodiment, such as Figure 2 , Figure 4 and Figure 5As shown, the cover 3 has a through hole 19 for the filter assembly 7 to pass through. The cleaning assembly 8 includes a mounting base 20, a cover plate 21, and several heating elements 22. The mounting base 20 is hollow and detachably installed at the through hole 19. The top of the mounting base 20 is provided with a cover plate 21, and heat dissipation holes are provided on the side wall of the mounting base 20. Several heating elements 22 are all arranged inside the mounting base 20 and are used to heat the filter assembly 7. It can be understood that when it is necessary to clean the impurities on the cleaning assembly 8, the filter assembly 7 can be inserted into the mounting base 20 through the through hole 19 on the cover 3. Several heating elements 22 are arranged inside the mounting base 20. The heating elements 22 can be infrared heating lamps, etc., which can melt away the fine particulate impurities on the filter assembly 7, thereby realizing automatic cleaning of the filter assembly 7. The structural design is simple and reasonable. In addition, the operator can set the heating temperature and time of the heating element 22 through the control system. Combined with the heat dissipation holes on the side wall of the mounting base 20, this effectively prevents overheating and heat damage to the filter assembly 7, making operation convenient and reliable. Furthermore, by using bolts or other methods to attach the cover plate 21 to the mounting base 20, not only is the inner cavity of the mounting base 20 sealed, providing a stable heating environment for the filter assembly 7, but it also facilitates the operator in opening the cover plate 21 to install and remove the heating element 22.

[0039] In one embodiment, the filter assembly 7 includes a second drive member 23 and a plurality of filter plates 24. The second drive member 23 is detachably mounted on the side wall of the housing 2 and is used to drive the plurality of filter plates 24 to extend into or retract from the mounting base 20. Specifically, as shown... Figure 2 , Figure 3 and Figure 5 As shown, the second driving component 23 can be a motor, and the filter plates 24 can be made of ceramic honeycomb mesh and activated carbon, etc., so as to filter out fine impurities in the circulating water. At the same time, the second driving component 23 can drive the filter plates 24 to extend into or out of the mounting base 20, so that the heating components 22 can heat the filter plates 24, thereby melting away the fine impurities on the filter plates 24 and restoring their filtration performance, ensuring the filtration and purification effect on the circulating water.

[0040] In one embodiment, a feeding pipe 25 communicating with the filter chamber 10 is provided on the cover 3, and an end cap is detachably installed at the opening of the feeding pipe 25. Specifically, as shown... Figure 1 , Figure 2 and Figure 5 As shown, the end cap and the feeding pipe 25 can be detachably installed by means of snap-fit ​​or threaded connection, which allows the staff to quickly and easily open the end cap and put the medicine and other related purification materials into the feeding pipe 25, so that the medicine can be smoothly transported into the filter chamber 10 through the feeding pipe 25. The operation is simple and convenient.

[0041] In one embodiment, a plurality of lifting rings 26 are arranged in a rectangular array on the lid 3; a plurality of hooks 27 are provided along the circumference of the outer wall of the base 1. Specifically, as shown... Figure 3 and Figure 4 As shown, several lifting rings 26 facilitate the lifting and opening or closing of the box cover 3 by external hoisting equipment; several hooks 27 facilitate the retrieval by external hoisting equipment for handling or moving the entire equipment, which is beneficial for transportation.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
