Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a treatment device for the green discharge of pectin wastewater. Background Art

[0002] As is well known, pectin itself is a macromolecular organic substance. In addition, the wastewater may also contain other organic substances such as sugars and proteins, resulting in relatively high chemical oxygen demand and biochemical oxygen demand of the wastewater. After fermentation in the wastewater, pectin will produce fruit acid, making the wastewater acidic. Therefore, compared with the treatment of ordinary domestic wastewater or industrial wastewater, it is more complex.

[0003] The problems existing in the prior art are as follows: The equipment required for normal pectin wastewater treatment is relatively cumbersome, and reagents need to be frequently added to cooperate with the air flotation system for treatment. Among them, a large number of equipment are required, and the floor area is also large, which is not conducive to the small-batch pectin production and processing environment. Based on the above-mentioned situation, we found that it is very difficult for the existing pectin wastewater treatment equipment to avoid the above problems at the same time. Even if it can be solved, it requires more processes and costs. Moreover, in steps such as acid neutralization, additional containers are required for treatment, and the efficiency is difficult to guarantee. At the same time, although large-size impurities can be quickly removed during the recycling of wastewater, it is also difficult to clean up the small-size solid waste residues after filtration, and it is inconvenient to use. Therefore, we propose a treatment device for the green discharge of pectin wastewater that can filter small-size waste residues directly when the raw water is put in, simultaneously perform acid balance treatment, can quickly clean the filtration equipment after operation, reduce the size of the device, integrate the equipment in the raw water treatment container, and is applicable to various scenarios. Summary of the Invention

[0004] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a treatment device for the green discharge of pectin wastewater, which has the advantages of being able to filter small-size waste residues directly when the raw water is put in, simultaneously perform acid balance treatment, can quickly clean the filtration equipment after operation, reduce the size of the device, integrate the equipment in the raw water treatment container, and is applicable to various scenarios.

[0005] (II) Technical Solutions The above technical object of the present invention is achieved through the following technical solutions: A treatment device for the green discharge of pectin wastewater, comprising a separation tank, a dissolved air cylinder, and a flocculation cylinder. The dissolved air cylinder and the flocculation cylinder are both fixedly connected to the bottom of the inner wall of the separation tank. A support rod is provided at the bottom of the flocculation cylinder, and the bottom of the support rod is welded to the separation tank. A transition frame is fixedly connected to the top of the inner wall of the separation tank, and a slag cylinder is fixedly connected to the top of the transition frame. A suspension rod is fixedly connected to the outside of the separation tank, and a suspension bracket is fixedly connected to the top of the suspension rod. An air flotation device is provided between the dissolved air cylinder and the flocculation cylinder; The slag cylinder includes an input pipe and a vertical cylinder. The left side of the vertical cylinder is integrally formed with the input pipe. A raw water valve is fixedly connected to the bottom of the vertical cylinder. A bottom hopper is provided outside the raw water valve. An isolation disk is fixedly connected to the inside of the vertical cylinder. Through holes are opened at the bottom of the isolation disk. A U-shaped frame is fixedly connected to the top of the isolation disk. A filter screen is fixedly connected to the top of the U-shaped frame. A top frame is fixedly connected to the top of the filter screen. A neutralization pipe is installed inside the U-shaped frame. A regulating valve is provided outside the neutralization pipe. The left side of the neutralization pipe penetrates through the U-shaped frame and the vertical cylinder and is externally connected to a lime milk pump. A slag removal component is provided between the filter screen and the vertical cylinder; The slag removal component includes an inverted disk, which is set as an annular structure with a semicircular cross-section. Fine screen meshes are provided on both the inner and outer sides of the top of the inverted disk, and a lifting frame integrally formed is provided between the outer fine screen mesh and the inner fine screen mesh; An adapter frame is fixedly connected to the outside of the vertical cylinder. A slag removal frame is slidably connected to the bottom of the adapter frame. A slag scraping plate is fixedly connected to the top of the slag removal frame, and the slag scraping plate is set to be inclined.

[0006] With the above technical solution, by setting a separation tank as the container for raw water treatment, and separating the internal area of the separation tank into different treatment uses through a dissolved air cylinder and a flocculation cylinder, the slag cylinder installed through the transition frame is used to input raw water into the device. After the raw water is filtered by the slag cylinder and flows along the transition frame into the separation tank, it is mixed with the flocculant, and then enters between the dissolved air cylinder and the flocculation cylinder along the bottom of the flocculation cylinder. At this time, dissolved air water is generated by the air flotation device, and the dissolved air water adheres to the outside of the flocculated suspended matter, and enters the outside of the dissolved air cylinder for separation under the continuous input of raw water. The suspended matter with a large number of microbubbles attached has a smaller overall density, so the flocs and bubbles will float on the surface of the separation tank, that is, floating slag is formed, achieving the effect of solid-liquid separation. The connecting frame located outside the slag cylinder cooperates with the slag removal frame. When the slag removal frame rotates along the connecting frame, the entire inclined scraping plate moves circumferentially at the top of the separation area of the separation tank, scraping the surface floating slag at the same time and shoveling it out of the separation tank. At this time, the water inside the separation tank can be continuously pumped by the pump equipment for subsequent treatment. After the raw water is injected into the vertical cylinder through the input pipe, it will be located between two layers of fine screens. At this time, the liquid can flow normally, while small-sized crushed slag will be filtered by the fine screens and deposited on the top of the inverted plate. The liquid will enter the middle of the vertical cylinder after passing through the fine screens and the filter screens. When the liquid passes between the two layers of filter screens, the neutralization pipe outputs alkaline lime milk to neutralize the fruit acid and make the wastewater closer to neutral. During the continuous flow and output process, it will also assist in mixing the lime milk with the raw water. Subsequently, the liquid can pass through the bottom hopper and the raw water feeder and be input into the separation tank for flocculation operation. After periodic operation, the entire slag removal assembly can be lifted by the lifting frame, which is convenient for cleaning the solid crushed slag accumulated in the slag removal assembly. After long-term use, clean water can be input to the bottom of the top frame, and the water flow can wash from the inside to the outside of the filter screen to flush out the impurities in the mesh holes, which is convenient for cleaning. Integrating multiple processes and optimizing the layout can effectively improve the treatment efficiency of wastewater during the treatment of pectin wastewater, while reducing the demand for floor space and facilitating installation and use in various sites.

The internal area of the separation tank is divided by a dissolved air cylinder and a flocculation cylinder for different treatment purposes. The slag cylinder installed through a transition frame is used to input raw water into the device. After the raw water is filtered by the slag cylinder and flows along the transition frame into the separation tank, it is mixed with a flocculant and enters the space between the dissolved air cylinder and the flocculation cylinder along the bottom of the flocculation cylinder. At this time, dissolved air water is generated by an air flotation device. The dissolved air water adheres to the outside of the flocculated suspended matter and enters the outside of the dissolved air cylinder for separation under the continuous input of the raw water. The suspended matter with a large number of microbubbles attached has a relatively small overall density, so the flocs and bubbles will float on the surface of the separation tank, that is, floating slag is formed, achieving the effect of solid-liquid separation. The connection frame located outside the slag cylinder cooperates with the slag removal frame. When the slag removal frame rotates along the connection frame, the entire inclined slag scraping plate moves circumferentially at the top of the separation area of the separation tank, scraping the surface floating slag at the same time and shoveling it out of the separation tank. At this time, the water inside the separation tank can be continuously pumped by a pump device for subsequent treatment.

When the liquid passes between the two layers of filter nets, the neutralization pipe outputs alkaline lime milk to neutralize the fruit acid to make the wastewater closer to neutral, and it will also assist in mixing the lime milk with the raw water during the continuous flow and output process. Subsequently, the liquid can pass through the bottom hopper and the raw water distributor and be input into the separation tank for flocculation operation. After periodic operation, the entire slag removal assembly can be lifted by a lifting frame, which is convenient for cleaning the solid crushed slag accumulated in the slag removal assembly. After long-term use, clean water can be input to the bottom of the top frame, and the water flow flushes from the inside to the outside of the filter net to wash out the impurities in the mesh holes, which is convenient for cleaning. Integrating multiple processes and optimizing the layout can effectively improve the treatment efficiency of the wastewater during the pectin wastewater treatment process, while reducing the demand for floor space and facilitating installation and use in various sites.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1-8 , a treatment device for green discharge of pectin wastewater, including a separation tank 1, a dissolved air cylinder 2 and a flocculation cylinder 3. The dissolved air cylinder 2 and the flocculation cylinder 3 are both fixedly connected to the bottom of the inner wall of the separation tank 1. A support rod is provided at the bottom of the flocculation cylinder 3, and the bottom of the support rod is welded to the separation tank 1. A transition frame 4 is fixedly connected to the top of the inner wall of the separation tank 1, and a slag cylinder 5 is fixedly connected to the top of the transition frame 4. A suspension rod 6 is fixedly connected to the outside of the separation tank 1, and a suspension bracket 7 is fixedly connected to the top of the suspension rod 6. An air flotation device is provided between the dissolved air cylinder 2 and the flocculation cylinder 3; The slag cylinder 5 includes an input pipe 501 and a vertical cylinder 502. A connection bracket 8 is fixedly connected to the outside of the vertical cylinder 502. A slag removal frame 9 is slidably connected to the bottom of the connection bracket 8. A scraper 10 is fixedly connected to the top of the slag removal frame 9, and the scraper 10 is set to be inclined; By setting the separation tank 1 as the container for raw water treatment, and separating the internal area of the separation tank 1 into different treatment uses through the dissolved air cylinder 2 and the flocculation cylinder 3, the slag cylinder 5 installed through the transition frame 4 is used to input the raw water into the device. After the raw water is filtered by the slag cylinder 5 and flows along the transition frame 4 into the separation tank 1, it is mixed with the flocculant, and then enters between the dissolved air cylinder 2 and the flocculation cylinder 3 along the bottom of the flocculation cylinder 3. At this time, the dissolved air water is generated by the air flotation device. The dissolved air water adheres to the outside of the flocculated suspended matter, and enters the outside of the dissolved air cylinder 2 for separation under the continuous input of the raw water. The suspended matter attached with a large number of microbubbles has a smaller overall density, so the flocs and bubbles will float on the surface of the separation tank 1, that is, the scum is formed, achieving the effect of solid-liquid separation. The connecting frame 8 located outside the slag cylinder 5 cooperates with the slag removal frame 9. When the slag removal frame 9 rotates along the connecting frame 8, the entire inclined scraping plate 10 moves circumferentially at the top of the separation area of the separation tank 1, while scraping the surface scum at the same time, so that it is shoveled out of the separation tank 1. At this time, the water inside the separation tank 1 can be continuously pumped by the pump equipment for subsequent treatment.

[0030] Among them, a transmission bracket 20 is fixedly connected to the outer side of the vertical cylinder 502, a reduction motor 21 is fixedly connected to the bottom of the transmission bracket 20, an internal gear 22 is fixedly connected to the inner side of the slag removal frame 9, an external gear 23 is fixedly connected to the output end of the reduction motor 21, and the internal gear 22 and the external gear 23 are meshed and connected. By setting the transmission bracket 20 to install the reduction motor 21, the reduction motor 21 drives the external gear 23 to rotate. While rotating, the internal gear 22 meshes and drives the external gear 23 to rotate. At this time, the connected slag removal frame 9 will be driven to rotate, so as to enable the slag scraping plate 10 to continuously perform the slag scraping action. A slag guiding flow channel 24 is fixedly connected to the outer side of the separation tank 1, and the slag guiding flow channel 24 is set to be inclined. By setting the slag guiding flow channel 24, after the slag scraping plate 10 scrapes off the floating slag, it will fall into the slag guiding flow channel 24 and flow along its inclined surface for convenient unified collection and treatment. A tank bracket 25 is provided at the bottom of the separation tank 1, a mixing motor 26 is provided at the bottom of the separation tank 1, the bottom of the mixing motor 26 is fixed to the installation position, and a hollow shaft 27 is installed at the output end of the mixing motor 26. By setting the tank bracket 25 to install the separation tank 1, the provided mixing motor 26 and the hollow shaft 27 are used to drive the structure to mix and stir the passing raw water. A check valve 28 is fixedly connected to the outer side of the hollow shaft 27, and a stirring shaft 29 is fixedly connected to the outer side of the hollow shaft 27. By setting the check valve 28, it is convenient for the flocculant to flow out of the check valve 28 after being input into the hollow shaft 27. The provided stirring shaft 29 can facilitate the mixing of the input flocculant and wastewater. The hollow shaft 27 includes a short section 271, a connecting column 272 is fixedly connected to the top of the short section 271, a long section 273 is fixedly connected to the top of the connecting column 272, the check valve 28 is installed inside the long section 273, the bottom of the short section 271 is fixedly connected to the output shaft of the mixing motor 26, a rotating ring 274 is movably connected to the outer side of the short section 271, the left side of the rotating ring 274 is externally connected to a flocculant supply pump, and the inner side of the rotating ring 274 is rotatably connected to the long section 273. By setting the short section 271 in cooperation with the connecting column 272 and the long section 273, the inside of the entire hollow shaft 27 allows the input of liquid, and through the hollow part of the connecting column 272, it is convenient to input the flocculant into the hollow shaft 27 through the flocculant supply pump and the rotating ring 274. When the mixing motor 26 drives the hollow shaft 27 to rotate along the rotating ring 274, the flocculant can be normally supplied. A shaft seal 30 is installed on the outer side of the long section 273, the shaft seal 30 is installed at the bottom of the separation tank 1, and a seal is provided on the inner side of the rotating ring 274. By setting the shaft seal 30, it can be avoided that the structure has poor sealing and causes water leakage, and the seal inside the rotating ring 274 can prevent the flocculant from leaking, ensuring normal supply.

[0031] Working principle of this embodiment: First, raw water enters the vertical cylinder 502 through the input pipe 501 of the slag cylinder 5, and is preliminarily filtered by the fine sieve mesh 510b of the slag removal assembly 510 in the vertical cylinder 502. Small-sized crushed slag is filtered out and precipitated on the top of the inverted plate 510a. The filtered raw water passes through the fine sieve mesh 510b and the filter mesh 507, and then through the bottom hopper 504 and the raw water valve 503, and flows into the separation tank 1 along the transition frame 4. The mixing motor 26 drives the hollow shaft 27 to rotate. The flocculant enters the hollow shaft 27 through the hollow part of the rotary ring 274 and the connecting column 272 by the flocculant supply pump, and then flows out from the one-way valve 28. The stirring shaft 29 mixes and stirs the flocculant and the raw water. The raw water mixed with the flocculant enters between the dissolved air cylinder 2 and the flocculation cylinder 3 along the bottom of the flocculation cylinder 3. The air flotation device generates dissolved air water, and the dissolved air water adheres to the outside of the flocculated suspended matter. Under the continuous input of raw water, it enters the outside of the dissolved air cylinder 2. Since the suspended matter with a large number of microbubbles attached has a relatively small overall density, the flocs and bubbles float on the surface of the separation tank 1 to form scum, realizing solid-liquid separation. The reduction motor 21 is installed through the transmission bracket 20, and it drives the outer gear 23 to rotate, meshes with the inner gear 22, and drives the slag removal frame 9 to rotate, so that the slag scraping plate 10 moves circumferentially at the top of the separation area of the separation tank 1 to scrape the surface scum. The scum falls into the inclined slag guiding channel 24 and flows along its inclined surface for unified collection and treatment. The water that has been preliminarily treated inside the separation tank 1 is continuously pumped by the pump equipment for subsequent treatment.

[0032] Embodiment 2: Refer to Figures 1-6 , a treatment device for the green discharge of pectin wastewater further includes a slag cylinder 5. Among them, the slag cylinder 5 includes an input pipe 501 and a vertical cylinder 502. The left side of the vertical cylinder 502 is integrally formed with the input pipe 501. The bottom of the vertical cylinder 502 is fixedly connected with a raw water valve 503. The outside of the raw water valve 503 is provided with a bottom hopper 504. The inner side of the vertical cylinder 502 is fixedly connected with a partition disk 505. The bottom of the partition disk 505 is provided with a through hole. The top of the partition disk 505 is fixedly connected with a U-shaped frame 506. The top of the U-shaped frame 506 is fixedly connected with a filter mesh 507. The top of the filter mesh 507 is fixedly connected with a top frame 508. A neutralization pipe 509 is installed inside the U-shaped frame 506. A regulating valve is provided outside the neutralization pipe 509. The left side of the neutralization pipe 509 penetrates through the U-shaped frame 506 and the vertical cylinder 502 and is externally connected to a lime milk pump. A slag removal assembly 510 is provided between the filter mesh 507 and the vertical cylinder 502; After the raw water is injected into the vertical cylinder 502 through the input pipe 501, it will be located between the two layers of fine screen meshes 510b. At this time, the liquid can flow normally, while the small-sized debris will be filtered down by the fine screen meshes 510b and deposited on the top of the inverted tray 510a. After the liquid passes through the fine screen meshes 510b and the filter net 507, it will enter the middle part of the vertical cylinder 502. When the liquid passes between the two layers of filter nets 507, the neutralization pipe 509 outputs alkaline lime milk to neutralize the fruit acid and make the wastewater closer to neutral. During the continuous flow and output process, it will also assist in mixing the lime milk with the raw water. Subsequently, the liquid can pass through the bottom hopper 504 and the raw water is sent to the separation tank 1 for flocculation operation. After the periodic operation, the entire slag removal assembly 510 can be lifted by the lifting frame 510c. At this time, it is convenient to clean the solid debris accumulated in the slag removal assembly 510. After long-term use, clean water can be input to the bottom of the top frame 508, and the water flow flushes outwards from the inner side of the filter net 507 to flush out the impurities in the mesh holes.

The bottom of the inner side of the inner rod 12 is fixedly connected with a tension spring 13. The top of the tension spring 13 is fixedly connected with the top of the inner side of the outer rod 11. By setting the outer rod 11 to cooperate with the inner rod 12, when it is necessary to clean the solid debris between the two layers of fine screen meshes 510b, a part of the inner rod 12 can be drawn out along the outer rod 11 together with the inverted tray 510a, so that there is enough space for the debris between the inverted tray 510a and the fine screen meshes 510b to be cleared out. When drawing out, the tension spring 13 is stretched and stores energy, and rebounds and drives the reset when there is no external force. The top of the suspension 7 is fixedly connected with a guide rail 14. The inner side of the guide rail 14 is rotatably connected with a lead screw 15. The outside of the lead screw 15 is threadedly connected with a slider 16. The outside of the slider 16 is slidably connected with the guide rail 14. The outside of the slider 16 is fixedly connected with an engagement ring 17. The bottom of the engagement ring 17 is fixedly connected with the lifting frame 510c. The outside of the engagement ring 17 is slidably connected with the suspension 7. By setting the guide rail 14 installed on the suspension 7 to cooperate with the lead screw 15, when the lead screw 15 rotates, the connected slider 16 will move vertically along the guide rail 14. During the movement of the slider 16, the connected engagement plate will move together with the lifting frame 510c to drive the slag removal assembly 510 to lift and lower. The bottom of the suspension 7 is fixedly connected with a pressing rod 18. The bottom of the pressing rod 18 is used in cooperation with the top of the inverted tray 510a. The inside of the suspension rod 6 is fixedly connected with a solid slag tray 19 used in cooperation with the inverted tray 510a. By setting the pressing rod 18 to cooperate with the inverted tray 510a, when the slag removal assembly 510 rises vertically, the top of the inverted tray 510a or the accumulated impurities will contact the pressing rod 18, and the inverted tray 510a is limited after contact. The fine screen meshes 510b and the outer rod 11 continue to rise along the inner rod 12 to expose the impurity cleaning space.

[0034] Working principle of this embodiment: First, raw water is injected into the vertical cylinder 502 from the input pipe 501 and located between the two layers of fine screens 510b of the slag removal component 510. Small-sized debris is filtered by the fine screen 510b and precipitated on the top of the inverted plate 510a, and the liquid passes through the fine screen 510b normally. When the liquid flows between the two layers of filter screens 507, the neutralization pipe 509 of the external lime milk pump outputs alkaline lime milk. The regulating valve controls the flow rate of lime milk to neutralize the fruit acid in the wastewater to make the wastewater closer to neutral. During the continuous flow and output of the water flow, the lime milk is further mixed with the raw water. After that, the liquid passes through the filter screen 507 and enters the middle part of the vertical cylinder 502, and then is input into the separation tank 1 through the bottom bucket 504 and the raw water valve 503 for subsequent flocculation operation. When it is necessary to clean the solid debris accumulated in the slag removal component 510, the screw rod 15 in the top guide rail 14 of the suspension 7 is rotated. The lead screw 15 drives the slider 16 threadedly connected thereto to move vertically along the guide rail 14, and the slider 16 drives the lifting frame 510c to rise through the connecting ring 17, thereby lifting the entire slag removal assembly 510. During the vertical rising process of the slag removal assembly 510, the top of the inverted plate 510a or the accumulated impurities contact the pressure rod 18 and are limited. At this time, the fine screen 510b and the outer rod 11 continue to rise along the inner rod 12, and the tension spring 13 at the bottom inner side of the inner rod 12 is stretched to store force, exposing the impurity cleaning space, which is convenient for cleaning the solid debris accumulated between the inverted plate 510a and the fine screen 510b. After cleaning, the external force is removed, and the tension spring 13 rebounds to drive the outer rod 11 and the fine screen 510b to reset. After long-term use, clean water is input to the bottom of the top frame 508, and the water flows from the inside of the filter 507 to the outside, flushing out the impurities in the mesh, thereby completing the cleaning of the filter 507.
