Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a deodorization device for environmentally friendly wastewater treatment. Background Technology

[0002] With the continuous development of the economy, the protection of the ecological environment and the rational and effective use of resources have become the focus of people's increasing attention. Among them, sewage deodorization has always been the primary task of sewage treatment, due to its strong odor diffusion and great harm.

[0003] The odor from sewage is mainly caused by the presence of pollutants such as starch, protein powder, and minerals. These organic substances ferment continuously, producing foul-smelling gases, which then diffuse into the air as the sewage flows.

[0004] Currently, there are many methods for wastewater treatment, but most of them require sedimentation and sludge removal. During this process, a large amount of odor is generated in the pretreatment room of the wastewater treatment plant. The main sources of odor are the primary sedimentation tank and lime slurry tank. The wastewater is also accompanied by foul odors. Existing technologies often use adsorption materials such as activated carbon to effectively purify and deodorize the wastewater. However, the wastewater also contains fine sludge and other solid particles, which seriously affects the purification efficiency and service life of adsorption materials such as activated carbon, increasing the cost of wastewater treatment. Therefore, further improvements are needed. Summary of the Invention

[0005] In order to reduce the particulate content in wastewater and improve the purification efficiency of adsorption materials, this application provides a deodorization device for wastewater environmental treatment.

[0006] This application provides a deodorization device for wastewater environmental treatment, which adopts the following technical solution: An odor control device for wastewater environmental treatment includes a tank, a water supply pipe passing through the tank for conveying wastewater into the tank, a filter plate disposed within the tank for wastewater filtration, a cleaning mechanism disposed within the tank for cleaning impurities filtered on the filter plate, an exhaust mechanism for absorbing odors emitted from the wastewater, a drain pipe disposed within the tank for discharging the filtered wastewater, and an adsorption deodorization box for adsorbing and deodorizing the wastewater in the drain pipe. The filter plates are spaced apart along the height of the tank. The cleaning mechanism includes a sludge discharge pipe with a sludge discharge port, a control component disposed on the sludge discharge pipe for opening and closing the sludge discharge port, a cleaning scraper disposed on the sludge discharge pipe for scraping impurities from the filter plate to the sludge discharge port, and a drive component for driving the cleaning scraper to rotate around the axis of the filter plate. The lower end of the sludge discharge pipe passes through the tank.

[0007] By adopting the above technical solution, a filter plate is installed to further filter some unfiltered impurities in the water. However, impurities that settle on the filter plate will affect the flow of subsequent water after a period of filtration, thus requiring regular cleaning. Specifically, the water is drained into the tank, then the control component is activated to open the sludge discharge port on the sludge discharge pipe, and the drive component is activated to drive the cleaning scraper to scrape the impurities on the filter plate to the sludge discharge port on the sludge discharge pipe. This cleans the impurities on the filter plate, reducing the need to open the tank for cleaning, as it can be done inside the tank. With the filtration of the filter plate, the particulate content in the wastewater is reduced, thereby improving the efficiency of subsequent purification of the wastewater by the adsorption material.

[0008] As some odorous gases in the wastewater flow to the extraction mechanism for deodorization, the filtered wastewater is discharged through the drain pipe into the adsorption and deodorization box for further adsorption and deodorization.

[0009] Preferably, the cleaning scraper abuts against the upper surface of the filter plate, the cleaning scraper is arc-shaped, the filter plate is conical, the tip of the filter plate faces the bottom wall of the tank, and the sludge discharge pipe passes through the middle of the filter plate and is coaxial with the filter plate.

[0010] By adopting the above technical solution, the cleaning scraper is set in an arc shape. Impurities of the same diameter on the filter plate are first scraped from the end of the cleaning scraper away from the sludge discharge pipe. As the cleaning scraper rotates, impurities of the same diameter are gradually scraped. The filter plate is set in a conical shape with the tip of the filter plate facing the bottom wall of the tank. This allows the impurities scraped by the cleaning scraper to move towards the sludge discharge pipe under the influence of gravity and fall into the sludge discharge port. Because the cleaning scraper is set in an arc shape, impurities away from the sludge discharge pipe are scraped down first. Then, due to the arc shape of the cleaning scraper itself, they can gradually move towards the sludge discharge port, which has a certain pushing effect on the impurities and allows them to enter the sludge discharge port. This reduces the possibility of impurities of the same diameter remaining between the cleaning scraper and the filter plate after being scraped.

[0011] Preferably, the cleaning scraper includes a plate body and a push plate rotatably connected to the plate body. The end of the push plate away from the sludge discharge pipe is a free end. The push plate is provided with a connecting belt connected to the control component and a reset member for abutting the push plate against the plate body for resetting.

[0012] By adopting the above technical solution, since the connecting belt is set between the control component and the push plate, as the control component controls the opening of the sludge discharge port, the connecting belt becomes taut, thereby driving the push plate to move closer to the sludge discharge pipe. When the control component closes the sludge discharge port, the connecting belt becomes loose, and at this time the reset component is used to push the push plate against the plate body for reset.

[0013] Preferably, the control component includes an abutment sleeve that is slidably connected to the inner wall of the sludge discharge pipe and a drive component that drives the abutment sleeve to rise and fall. The height of the abutment sleeve is greater than the height of the sludge discharge port, and the connecting strip is connected to the abutment sleeve.

[0014] By adopting the above technical solution, the abutting sleeve abuts against the inner wall of the sludge discharge pipe to seal the sludge discharge port. When the sludge discharge port needs to be opened, the drive component is activated to lift the abutting sleeve, opening the sludge discharge port. Then, the drive assembly is activated to rotate the cleaning scraper, scraping the impurities deposited on the filter plate. As the filter plate moves closer to the sludge discharge port, the impurities fall into the sludge discharge pipe and are discharged into the tank. A connecting belt is installed on the abutting sleeve. As the abutting sleeve rises, the connecting belt becomes taut. As the abutting sleeve continues to rise, the push plate moves closer to the sludge discharge pipe, moving impurities closer to the sludge discharge port to accelerate impurity discharge. When the abutting sleeve descends, causing the connecting belt to relax, the push plate abuts against the plate body to reset under the action of the reset component.

[0015] Preferably, the bottom of the tank is provided with an mounting plate for mounting the drive assembly. The drive assembly includes a first drive motor fixedly connected to the mounting plate, a gear coaxially sleeved on the output shaft of the first drive motor, and a gear ring coaxially sleeved on the outer peripheral wall of the sludge discharge pipe. The gear meshes with the gear.

[0016] By adopting the above technical solution, since the abutting sleeve abuts against the inner wall of the sludge discharge pipe to block the sludge discharge port, when the sludge discharge port needs to be opened, the driving component is activated to drive the abutting sleeve to rise and open the sludge discharge port. At the same time, the first driving motor is activated to drive the gear and gear ring to rotate, thereby driving the sludge discharge pipe to rotate, so that the cleaning scraper rotates around the axis of the filter plate to scrape the impurities deposited on the filter plate. As the filter plate moves towards the direction of the sludge discharge port, it falls into the sludge discharge pipe and is discharged into the tank.

[0017] Preferably, the driving component includes a bracket fixedly connected to the inner wall of the sludge discharge pipe, a screw threaded through the bracket, and a fixing collar coaxially fixedly connected to the screw, with a connecting rod provided between the fixing collar and the abutting sleeve.

[0018] By adopting the above technical solution, and by setting a bracket fixedly connected to the inner wall of the sludge discharge pipe, the screw rotates as the sludge discharge pipe rotates, thereby causing the fixed collar to rotate along the screw. Specifically, when the sludge discharge pipe rotates forward, the fixed collar rises with the rotation of the screw to open the sludge discharge port; when the sludge discharge pipe rotates in reverse, the fixed collar falls with the rotation of the screw to close the sludge discharge port. By controlling the opening and closing of the sludge discharge port through the rotation of the sludge discharge pipe, the cost of separately controlling the raising and lowering of the abutment sleeve can be reduced.

[0019] Preferably, the abutting sleeve is provided with a sealing plate for sealing the sludge discharge port and an elastic element for pushing the sealing plate toward the sludge discharge port. The abutting sleeve has a sliding groove for the sealing plate to slide and connect, and the elastic element is built into the sliding groove. The sealing plate protrudes from the sludge discharge port, and a first guide surface is provided at the upper end of the sealing plate. The inner wall of the sludge discharge pipe near the sludge discharge pipe has a second guide surface for abutting against the first guide surface. When the abutting sleeve is raised, the sealing plate retracts into the sliding groove to open the sludge discharge port.

[0020] By adopting the above technical solution, since the filter plate is cone-shaped, most impurities will be located in the middle of the filter plate. Furthermore, due to the thickness difference between the abutting sleeve and the inner wall of the sludge discharge pipe, impurities located in the middle of the filter plate may accumulate at the sludge discharge port. When the abutting sleeve is opened subsequently, it may block the inner wall of the sludge discharge pipe at the sludge discharge port, affecting the flow of subsequent impurities. Therefore, by installing a sealing plate, when filtering wastewater, the abutting sleeve closes the sludge discharge port, and the sealing plate protrudes from the sludge discharge port as the elastic element pushes it, thus cleaning the impurities adhering to the sludge discharge port. To open the sludge discharge port, the sealing plate slides away from it when the abutting sleeve rises. The cooperation of the first and second guide surfaces causes the sealing plate to move closer to the abutting sleeve, thus opening the sludge discharge port.

[0021] Preferably, the control component includes an installation sleeve, an airbag coaxially sleeved outside the installation sleeve, and a control component for inflating or deflating the airbag. The airbag is elastic, and a cavity is left between the airbag and the installation sleeve. An installation rod is fixedly connected to the upper end of the installation sleeve, and the installation rod is fixedly connected to the inner wall of the sludge discharge pipe. The airbag is connected to the connecting belt.

[0022] By adopting the above technical solution, when it is necessary to filter the sewage in the tank, the control unit is activated to inflate the air bladder, causing the air bladder to expand and block the sludge discharge port. At this time, the connecting belt is in a loose state. When it is necessary to discharge impurities from the tank, the control unit is activated to suck the gas in the air bladder, causing the air bladder to retract and tighten the connecting rope. As the air bladder retracts, it causes the connecting rope to move closer to the air bladder, which in turn causes the push plate to move closer to the air bladder, pushing the scraped impurities to the sludge discharge port.

[0023] Preferably, the control component includes an air tube fixedly inserted into the airbag and an air pump fixedly connected to the air tube. The end of the air tube away from the airbag is fixedly inserted into the sludge discharge pipe, and the air pump is located outside the tank body.

[0024] In summary, this application has the following beneficial effects: The filter plates further filter unfiltered impurities in the water. After a certain filtration time, the control component is activated to open the sludge discharge port on the sludge discharge pipe, and the drive component is activated to drive the cleaning scraper to scrape the impurities on the filter plates to the sludge discharge port on the sludge discharge pipe. This cleans the impurities on the filter plates, reducing the need to open the tank for cleaning, which can be done inside the tank. As the filter plates filter, the particle content in the wastewater is reduced, thereby improving the efficiency of subsequent purification of the wastewater by the adsorption material.

[0027] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail below.

[0028] This application discloses an odor removal device for wastewater environmental treatment.

[0029] Example: A deodorization device for wastewater environmental treatment, referring to Figure 1 , Figure 2 It includes a tank 1, a water supply pipe 11 fixedly installed in the tank 1 for conveying sewage into the tank 1, a filter plate 12 installed in the tank 1 for filtering sewage, a cleaning mechanism 2 installed in the tank 1 for cleaning the impurities filtered on the filter plate 12, an air extraction mechanism 3 for absorbing the odor emitted from the sewage, a drain pipe 13 installed in the tank 1 for discharging the filtered sewage, and an adsorption and deodorization box 4 for adsorbing and deodorizing the sewage in the drain pipe 13.

[0030] The tank 1 has an open top wall and a lid 14 for opening and closing. Support legs 15 are fixedly connected to the bottom wall of the tank 1, and several support legs 15 are spaced apart along the axis of the tank 1. Valves 16 are installed on both the water supply pipe 11 and the drain pipe 13. In this embodiment, the filter plate 12 is conical, with its tip facing the bottom wall of the tank 1. Several filter plates 12 are spaced apart along the height of the tank 1; for example, two filter plates 12 are used, but the number can be adjusted according to requirements. The outer peripheral wall of the filter plate 12 is fixedly connected to the inner wall of the tank 1, and the specific fixing method can be achieved using bolts. Since this is existing technology, it will not be described in detail here.

[0031] Reference Figure 2 , Figure 3 The cleaning mechanism 2 includes a sludge discharge pipe 21, a control component 22, a cleaning scraper 23, and a drive component 24. Specifically, the sludge discharge pipe 21 is used to discharge impurities on the filter plate 12 to the outside of the tank 1. The sludge discharge pipe 21 has a sludge discharge port 211 so that impurities on the filter plate 12 can be discharged from the sludge discharge port 211. The control component 22 is used to open and close the sludge discharge port 211 as needed. In this embodiment, the sludge discharge pipe 21 is rotatably inserted through the bottom wall of the tank 1, extends into the tank 1, and rotatably inserts through the filter plate 12, and is coaxially arranged with the filter plate 12. Several sludge discharge ports 211 are provided at intervals along the height direction of the sludge discharge pipe 21. Since some impurities will also remain on the bottom wall of the tank body 1, in this embodiment, three sludge discharge ports 211 are provided, corresponding to the two filter plates 12 and the bottom wall of the tank body 1, respectively. The lower end of the sludge discharge port 211 provided near the filter plate 12 is flush with the upper surface of the filter plate 12, while the lower end of the sludge discharge port 211 provided near the bottom wall of the tank body 1 is flush with the inner bottom wall of the tank body 1.

[0032] Reference Figure 3 , Figure 4 The control component 22 includes an abutment sleeve 221 slidably connected to the inner wall of the sludge discharge pipe 21 and a drive component 222 for driving the abutment sleeve 221 to rise and fall. In this embodiment, several abutment sleeves 221 are spaced apart along the height direction of the sludge discharge pipe 21, specifically three. The height of the abutment sleeves 221 is greater than the height of the sludge discharge port 211 to improve the sealing effect of the sludge discharge port 211. The connection between adjacent abutment sleeves 221 is specifically fixed by a fixing rod 2211. The drive component 222 is an electric push rod. A fixing plate 2221 is fixedly connected between the electric push rod and the inner wall of the sludge discharge pipe 21. The output shaft of the electric push rod is fixedly connected to a connecting rod 2222, which is fixedly connected to the inner wall of the lowest abutment sleeve 221. Activating the electric push rod drives the abutment sleeve 221 to rise or fall, thereby opening or closing the sludge discharge port 211.

[0033] Furthermore, to reduce the possibility of impurities blocking the sludge discharge port 211, in this embodiment, a sealing plate 5 and an elastic element 51 are provided on the abutment sleeve 221. The sealing plate 5 is used to seal the sludge discharge port 211. The abutment sleeve 221 has a sliding groove 2212 for the sealing plate 5 to slide and connect. The elastic element 51 is built into the sliding groove 2212. In this embodiment, the elastic element 51 is a spring. The elastic element 51 is used to push the sealing plate 5 to move towards the sludge discharge port 211. When the sealing plate 5 is set corresponding to the sludge discharge, the sealing plate 5 blocks the sludge discharge port 211 and is flush with the outer peripheral wall of the sludge discharge pipe 21. The upper end of the sealing plate 5 is provided with a first guide surface 52, and the inner wall of the mud discharge pipe 21 near the mud discharge pipe 21 is provided with a second guide surface 212 for abutting against the first guide surface 52. When the abutting sleeve 221 is raised, the sealing plate 5 is retracted into the slide groove 2212 to open the mud discharge port 211.

[0034] Reference Figure 2 , Figure 3 The cleaning scraper 23 is used to scrape impurities on the filter plate 12 to the sludge discharge port 211, and the drive assembly 24 is used to drive the cleaning scraper 23 to rotate around the axis of the filter plate 12 to scrape the impurities on the filter plate 12. In this embodiment, the cleaning scraper 23 is disposed on the outer peripheral wall of the sludge discharge pipe 21, and the cleaning scrapers 23 are spaced apart along the height direction of the sludge discharge pipe 21, with the number of scrapers being the same as the number of sludge discharge ports 211, respectively abutting against the upper surface of the filter plate 12 and the inner bottom wall of the tank 1.

[0035] Reference Figure 5 , Figure 6 The cleaning scraper 23 specifically includes a plate body 231, a push plate 232 rotatably connected to the plate body 231, and a rubber scraper 233 fixedly connected to the lower ends of the plate body 231 and the push plate 232 respectively. The end of the push plate 232 away from the mud discharge pipe 21 is a free end.

[0036] To push the push plate 232, in this embodiment, the push plate 232 is provided with a connecting band 6 connected to the sealing plate 5 and a reset member 7 for abutting the push plate 232 against the plate body 231 for resetting. When the sludge discharge port 211 is opened, the sealing plate 5 moves away from the sludge discharge port 211, so that the connecting band 6 is tightened, thereby driving the push plate 232 to move closer to the sludge discharge pipe 21; when the sludge discharge port 211 is closed, the connecting band 6 is loosened, and at this time the reset member 7 is used to abut the push plate 232 against the plate body 231 for resetting. In this embodiment, the reset member 7 is a reset spring, which forces the push plate 232 to move closer to the plate body 231. The side wall of the plate body 231 near the push plate 232 is provided with a mounting groove 2311 for fixing the reset spring, and the reset spring is located near the sludge discharge pipe 21.

[0037] Back Figure 3 For the installation of the drive assembly 24, the outer bottom wall of the tank body 1 is provided with a mounting plate 17 for mounting the drive assembly 24. The drive assembly 24 includes a first drive motor 241 fixedly connected to the mounting plate 17, a gear 242 coaxially sleeved on the output shaft of the first drive motor 241, and a gear ring 243 coaxially sleeved on the outer peripheral wall of the sludge discharge pipe 21. The gear 242 meshes with the gear ring 243. When the first drive motor 241 is started, it sequentially drives the gear 242, the gear ring 243, and the sludge discharge pipe 21 to rotate, thereby driving the cleaning scraper 23 set on the sludge discharge pipe 21 to scrape the impurities on the filter plate 12.

[0038] Back Figure 1 , Figure 2 The air extraction mechanism 3 includes an exhaust pipe fixedly installed at the upper end of the tank 1, an ultraviolet lamp (not shown in the figure) built into the exhaust pipe, and an air pump fixedly connected to the exhaust pipe outlet. It should be noted that the height of the exhaust pipe is higher than the height of the filter plate 12 and higher than the height of the conveying pipe. The height of the sewage liquid level entering the tank 1 needs to be less than the height of the exhaust pipe to reduce the sewage flow into the exhaust pipe.

[0039] Reference Figure 1 , Figure 7 The adsorption deodorization box 4 is equipped with a water spray pipe 41 connected to the drain pipe 13. Atomizing nozzles 411 are installed on the water spray pipe 41, with several atomizing nozzles 411 spaced apart along the length of the water spray pipe 41. An adsorption layer 42 is located below the atomizing nozzles 411 within the adsorption deodorization box 4. In this embodiment, the adsorption layer 42 can be an adsorbent material such as adsorbent carbon or activated coke, depending on the requirements. In this embodiment, a connecting pipe 43 is fixedly installed through the top wall of the adsorption deodorization box 4. The connecting pipe 43 is connected to an exhaust pipe so that the gas volatilized from the atomized wastewater enters the exhaust pipe through the connecting pipe 43 and is deodorized by an ultraviolet lamp at the exhaust pipe. The atomized water is then adsorbed and deodorized by the adsorption layer 42 below.

[0040] The implementation principle of the deodorization device for wastewater environmental treatment in this application embodiment is as follows: A filter plate 12 is installed to further filter some unfiltered impurities in the water. However, impurities that settle on the filter plate 12 will affect the flow of subsequent water after a period of filtration, thus requiring periodic cleaning. Specifically, the water is drained into the tank 1. Then, the control component 22 is activated to open the sludge discharge port 211 on the sludge discharge pipe 21, and the drive component 24 is activated to drive the cleaning scraper 23 to scrape the impurities on the filter plate 12 to the sludge discharge port 211 on the sludge discharge pipe 21. This cleans the impurities on the filter plate 12, reducing the need to open the tank 1 for cleaning, as the cleaning can be done inside the tank 1. With the filtration of the filter plate 12, the particulate content in the wastewater is reduced, thereby improving the efficiency of subsequent purification of the wastewater by the adsorption material.

[0041] Example 2: Reference Figure 8 The difference from Embodiment 1 is that the driving component 222 includes a bracket 2223 fixedly connected to the inner wall of the sludge discharge pipe 21, a screw 2224 threaded through the bracket 2223, and a fixing collar 2225 coaxially fixedly connected to the screw 2224. In this embodiment, the fixing collar 2225 is provided with one ring and is coaxially arranged with the abutment sleeve 221 located at the bottom. A connecting rod 2222 is also fixedly connected between the fixing collar 2225 and the abutment sleeve 221 to fix the fixing collar 2225 and the abutment sleeve 221. When the sludge discharge pipe 21 rotates, it drives the bracket 2223 to rotate, thereby driving the screw 2224 to rotate and rise. Example

[0042] Reference Figure 9 , Figure 10 The difference from Embodiment 1 is that the control component 22 includes a mounting sleeve 223, an airbag 224 coaxially sleeved outside the mounting sleeve 223, and a control component 225 for inflating or deflating the airbag 224. The mounting sleeve 223 is built into the sludge discharge pipe 21 and is coaxially arranged with the sludge discharge pipe 21. In this embodiment, the airbag 224 is elastic and has a cavity 2241 inside to allow gas to be retained. An mounting rod (not shown in the figure) is fixedly connected to the upper end of the mounting sleeve 223. The mounting rod is fixedly connected to the inner wall of the sludge discharge pipe 21. At this time, the connecting strap 6 is connected to the airbag 224.

[0043] The control component 225 includes an air pipe 2251 fixedly inserted into the airbag 224 and an air pump 2252 fixedly connected to the air pipe 2251. The end of the air pipe 2251 away from the airbag 224 is fixedly inserted into the mud discharge pipe 21, and the air pump 2252 is located outside the tank body 1.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
