Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wastewater purification, in particular to a wastewater stratified purification device. Background Technique
[0002] With the improvement of people's living standards, a large amount of wastewater is discharged every day in both industrial production and people's daily life. Most of this wastewater contains oil stains, chemical metal substances, etc. Wastewater purification is to use physical, chemical, and biological methods to treat wastewater, purify the wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources.
[0003] Existing wastewater purification equipment needs to include a solid-liquid separation part. Generally, solid-liquid separation is carried out through a filter screen, and oil-water separation is achieved through natural density stratification and penetration. Then, the separated wastewater is discharged. Due to the long-term use of the wastewater purification equipment, the filter screen for solid-liquid separation is easily blocked by the filtered solid debris. It is inconvenient for operators to disassemble and clean the filter screen. At the same time, it is difficult for operators to master when and the degree of blockage. Frequent disassembly and installation of the wastewater purification equipment are likely to increase the usage loss of the equipment, which is not conducive to extending the service life. Manual cleaning consumes a lot of time and energy, which is not conducive to reducing production costs.
[0004] Therefore, a wastewater stratified purification device is proposed. Content of the Utility Model
[0005] The purpose of the utility model is: to solve the problems mentioned in the above background technique, the utility model provides a wastewater stratified purification device.
[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:
[0007] A wastewater stratified purification device includes a purification tank. A water inlet pipe is fixedly installed on the top surface of the purification tank. A partition is fixedly installed on the inner wall surface of the purification tank. A coarse filter screen is fixedly installed between the top surface of the partition and the top surface of the inner wall of the purification tank. A silt removal mechanism is arranged on the right surface of the purification tank. A cleaning mechanism is arranged on the inner wall surface of the purification tank. The cleaning mechanism is located on the left side of the coarse filter screen and above the partition. A drainage port is opened on the surface of the partition. A miscellaneous storage cabin is arranged below the partition. A fine filter screen and an activated carbon filter screen are fixedly installed between the outer side wall of the miscellaneous storage cabin and the inner wall of the purification tank. The fine filter screen and the activated carbon filter screen are arranged vertically. A water level sensor is fixedly installed on the left inner wall surface of the purification tank. The number of water level sensors is several and they are arranged in a row from front to back.
[0008] Furthermore, the silt removal mechanism includes a first electric push rod, which is fixedly installed on the right side surface of the purification box, and a push plate is fixedly installed on the telescopic end of the first electric push rod. The push plate is slidably arranged close to the surface of the purification box and the partition, and a cleaning cone is fixedly installed on the side surface of the push plate facing the coarse filter screen. The number of the cleaning cones is several and evenly distributed, and the size and number of the cleaning cones are the same as the size and number of the filter holes on the surface of the coarse filter screen.
[0009] Furthermore, there are a plurality of drainage openings which are evenly distributed on the right side of the partition surface.
[0010] Furthermore, the cleaning mechanism includes a second electric push rod, which is fixedly installed on the back of the purification box, and a scraper is fixedly installed on the telescopic end of the second electric push rod. The scraper is slidably arranged close to the surface of the partition, and a lower silt opening is opened on the surface of the partition, and the lower silt opening is located on the left side of the coarse filter.

[0013] The beneficial effects of the present invention are as follows: when the coarse filter is blocked, wastewater is difficult to discharge in the solid-liquid separation layer, causing the water level to rise and overflow the water level sensor. At this time, the water level sensor works and sends a signal to the desilting mechanism, so that the desilting mechanism can slide to the side of the coarse filter and clean up the debris clogged on the surface of the filter holes of the coarse filter. The cleaned debris falls on the left side of the coarse filter. When the desilting mechanism resets the wastewater level and drops to below the water level sensor for a period of time, a signal is sent to the cleaning mechanism through the water level sensor to start working, so that the debris in the solid-liquid separation layer can be cleaned into the storage compartment. The operator does not need to frequently clean and replace the filter screen to clean the filter screen, which saves a lot of time and energy, and is conducive to improving work efficiency and extending the service life of the equipment.

[0023] Such as Figures 1 to 3As shown in the figure, a wastewater stratified purification device includes a purification tank 1. A water inlet pipe 12 is fixedly installed on the top surface of the purification tank 1. A partition plate 2 is fixedly installed on the inner wall surface of the purification tank 1. A coarse filter screen 3 is fixedly installed between the top surface of the partition plate 2 and the top inner wall surface of the purification tank 1. A silt removal mechanism 4 is provided on the right surface of the purification tank 1. A cleaning mechanism 5 is provided on the inner wall surface of the purification tank 1. The cleaning mechanism 5 is located on the left side of the coarse filter screen 3 and above the partition plate 2. A drain port 6 is formed on the surface of the partition plate 2. A miscellaneous storage compartment 9 is provided below the partition plate 2. A fine filter screen 7 and an activated carbon filter screen 8 are fixedly installed between the outer wall of the miscellaneous storage compartment 9 and the inner wall of the purification tank 1. The fine filter screen 7 and the activated carbon filter screen 8 are arranged vertically. A water level sensor 11 is fixedly installed on the left inner wall surface of the purification tank 1. The number of the water level sensors 11 is several and they are arranged in a row front and back.
[0024] Specifically, the partition plate 2 divides the purification tank 1 into two upper and lower spaces. The upper part is the solid-liquid separation layer. Wastewater enters the solid-liquid separation layer through the water inlet pipe 12. When the coarse filter screen 3 is blocked, it is difficult for the wastewater to drain out in the solid-liquid separation layer, resulting in the water level rising and overflowing the water level sensor 11. At this time, the water level sensor 11 works and sends a signal to the silt removal mechanism 4, enabling the silt removal mechanism 4 to slide towards the side of the coarse filter screen 3 and clean the sundries blocked on the surface of the filter holes of the coarse filter screen 3. The sundries being cleaned fall to the left side of the coarse filter screen 3. After the silt removal mechanism 4 resets and the wastewater level drops below the water level sensor 11 for a period of time, a signal is sent to the cleaning mechanism 5 through the water level sensor 11 to make the cleaning mechanism 5 start working. Thus, the sundries in the solid-liquid separation layer can be cleaned into the miscellaneous storage compartment 9. The water that has been preliminarily treated passes through the drain port 6 and then enters the lower part of the partition plate 2 and is further treated through the fine filter screen 7 and the activated carbon filter screen 8. The purified wastewater can be discharged through the water outlet 10. The operator does not need to clean and replace the filter screen frequently, saving a lot of time and energy, which is beneficial to the improvement of work efficiency. The filter screen can be cleaned without frequent disassembly, which is beneficial to the extension of the service life of the device. The water level sensors 11 are arranged in a row, which can effectively avoid the situation that the device fails to work due to the wastewater splashing on the surface of the water level sensors 11 when the water enters.
[0025] As Figures 2 to 3 shown in the figure, the silt removal mechanism 4 includes a first electric push rod 401. The first electric push rod 401 is fixedly installed on the right surface of the purification tank 1. A push plate 402 is fixedly installed at the telescopic end of the first electric push rod 401. The push plate 402 is slidably arranged in close contact with the surfaces of the purification tank 1 and the partition plate 2. A cleaning cone 403 is fixedly installed on the surface of the push plate 402 facing the coarse filter screen 3. The number of the cleaning cones 403 is several and they are evenly distributed. The size and number of the cleaning cones 403 are the same as the size and number of the filter holes on the surface of the coarse filter screen 3.
[0026] Specifically, the first electric push rod 401 can drive the push plate 402 to slide along the inner wall surface of the partition 2 and the purification box 1 toward the side of the coarse filter 3 until the surface of the push plate 402 is in close contact with the surface of the coarse filter 3. At this time, the cleaning cone 403 coincides with the filter holes on the surface of the coarse filter 3, and the debris in the filter holes can be pushed out, thereby realizing the cleaning function of the coarse filter 3.
[0027] like Figures 2 to 3 As shown, there are a plurality of drain ports 6 which are evenly distributed on the right side of the surface of the partition plate 2 .
[0028] Specifically, a large number of drainage ports 6 facilitates the rapid entry of preliminarily treated wastewater into the next layer for purification, which is beneficial to improving work efficiency.
[0029] like Figures 2 to 3 As shown, the cleaning mechanism 5 includes a second electric push rod 501, which is fixedly installed on the back of the purification box 1. A scraper 502 is fixedly installed on the telescopic end of the second electric push rod 501. The scraper 502 is slidably arranged close to the surface of the partition 2. A lower silt opening 503 is opened on the surface of the partition 2, and the lower silt opening 503 is located on the left side of the coarse filter 3. A third electric push rod 505 is fixedly installed on the top surface of the purification box 1, and a sealing plug 504 is fixedly installed on the telescopic end of the third electric push rod 505.
[0030] Specifically, when the cleaning mechanism 5 is working, the third electric push rod 505 drives the sealing plug 504 to move upward and detach from the surface of the lower silt outlet 503, and the second electric push rod 501 drives the scraper 502 to slide forward, so that the debris accumulated on the surface of the partition 2 is pushed to the lower silt outlet 503 and falls into the storage compartment 9 through the lower silt outlet 503, so that the debris on the surface of the partition 2 can be cleaned, and the scraper 502 and the sealing plug 504 can continue to be purified only after the reset.
[0031] like Figure 3 As shown, the specifications of the sealing plug 504 are compatible with the specifications of the lower silt outlet 503.
[0032] Specifically, the specifications of the lower silt opening 503 and the sealing plug 504 are adapted to each other so that the lower silt opening 503 can be sealed, and the wastewater will not leak out through the lower silt opening 503 when filtered in the solid-liquid separation layer, making the structure of the wastewater purification equipment safer and more reliable.
[0033] like Figures 1 to 3 As shown, the storage compartment 9 includes a cleaning port 901 , which is opened on the side wall of the purification box 1 , and a sealing door 902 is hingedly connected to the side wall of the purification box 1 , and the specification of the sealing door 902 is adapted to the cleaning port 901 .
[0034] Specifically, the cleared sundries accumulate inside the sundry storage cabin 9. By opening the sealing door 902, the sundries inside the sundry storage cabin 9 can be removed from inside the purification tank 1 through the cleaning port 901.
[0035] In summary: when the coarse filter screen 3 is blocked, the wastewater is difficult to drain in the solid-liquid separation layer, causing the water level to rise and overflow the water level sensor 11. At this time, the water level sensor 11 works to send a signal to the silt removal mechanism 4, enabling the silt removal mechanism 4 to slide towards the coarse filter screen 3 and clean the sundries blocked on the surface of the filter holes of the coarse filter screen 3. The cleared sundries fall to the left of the coarse filter screen 3. After the silt removal mechanism 4 resets and the wastewater level drops below the water level sensor 11 for a period of time, the water level sensor 11 sends a signal to the cleaning mechanism 5 to make the cleaning mechanism 5 start working. Thus, the sundries in the solid-liquid separation layer can be cleaned into the sundry storage cabin 9. The operator can clean the filter screen without frequently cleaning and replacing the filter screen, saving a lot of time and effort, which is beneficial to the improvement of work efficiency and the extension of the service life of the equipment.
