Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an acid-base neutralization tank. Background Technology

[0002] Wastewater generated during existing production processes is generally treated centrally in acid-base neutralization tanks to meet environmental emission standards before being discharged. Existing acid-base neutralization tanks typically use aeration components to stir the wastewater and add chemicals to ensure thorough mixing of the wastewater and chemicals.

[0003] However, since the aeration components are located at the bottom of the pool, they are easily blocked by sediment in the wastewater. Some existing technologies have eliminated the aeration components and changed to a stirring method, but the stirring is still incomplete, resulting in uneven mixing of wastewater and chemicals in the acid-base neutralization pool, which can easily lead to non-compliance with environmental protection standards. Utility Model Content

[0004] The main purpose of this utility model is to provide an acid-base neutralization tank to solve the problem of incomplete stirring in the existing technology, which leads to uneven mixing of wastewater and reagents in the acid-base neutralization tank and easily causes non-compliant emissions.

[0005] To solve the above problems, the present invention adopts the following technical solution: an acid-base neutralization tank, comprising a tank body, a drug dilution tank provided on one side of the top of the tank body, the drug dilution tank being connected to the tank body on one side, a submersible pump provided on one side of the bottom of the tank body, the output end of the submersible pump being connected to the drug dilution tank and the outside of the tank body respectively through pipelines, a stirring device being slidably provided on the top of the tank body, and a first power unit for driving the stirring device to reciprocate along the length of the tank body on one side.

[0006] Furthermore, two slide rails are fixedly provided at a distance from the top of the pool body. The stirring device includes a moving component and a stirring component. The upper part of the moving component is slidably disposed on the two slide rails, and the stirring component is rotatably disposed on the lower part of the moving component. A second power unit for driving the stirring component to rotate is fixedly provided at the top of the moving component.

[0007] Furthermore, the moving assembly includes a moving plate slidably connected to the two slide rails and a housing fixed to the bottom end of the moving plate. The stirring assembly includes two shafts, which are respectively horizontally arranged on opposite sides of the housing and rotatably connected to the housing. A plurality of stirring rods are uniformly fixed on the shaft located on the outside of the housing. The second power unit includes a drive rod vertically arranged inside the housing and a first motor fixed to the top surface of the moving plate for driving the drive rod to rotate. A first helical gear is fixed to the bottom end of the drive rod. One end of each of the two shafts passes through the side wall of the housing and extends into the interior of the housing, and is respectively fixed with a second helical gear meshing with the first helical gear.

[0008] Furthermore, the first power unit includes a lead screw rotatably mounted at the top of the pool body and a second motor mounted on one side of the pool body. The output end of the second motor is fixedly connected to one end of the lead screw, and the other end of the lead screw extends through the movable plate to the other side of the pool body, and the lead screw is screwed to the movable plate.

[0009] Furthermore, a scraping assembly is fixedly installed at the bottom of the housing.

[0010] Furthermore, the scraping assembly includes two spaced-apart support rods, the top ends of which are fixedly connected to the bottom end of the housing, and the bottom ends of which extend toward the bottom surface of the pool and are fixedly provided with scrapers, the long axis of which is parallel to the width direction of the pool.

[0011] Furthermore, the scraper has a trapezoidal structure that is narrower at the top and wider at the bottom.

[0012] Furthermore, the pipeline includes a first connecting pipe connected to the output end of the submersible pump. The end of the first connecting pipe away from the submersible pump is respectively connected to a second connecting pipe and a third connecting pipe. The output end of the second connecting pipe extends into the interior of the drug dilution tank, and the output end of the third connecting pipe extends outward from the tank. Solenoid valves are respectively provided on the second connecting pipe and the third connecting pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up submersible pumps and pipelines to connect the drug dilution tank and the outside of the tank respectively, the wastewater in the tank can be circulated internally or externally. In the internal circulation state, the submersible pump can suck out the undissolved alkali at the bottom of the tank and discharge it back into the tank through the drug dilution tank, so that the alkali can be fully dissolved and the dissolution time can be reduced. At the same time, the submersible pump discharges the water in the tank into the drug dilution tank, which can dissolve the drug in advance.

[0015] 2. By setting up a stirring device in conjunction with the first power unit, the stirring device can move back and forth along the length of the tank, thereby fully stirring the wastewater in the tank and ensuring that the reagent and wastewater are fully mixed.

[0016] 3. By setting up a scraping component, the sediment deposited at the bottom of the tank can be scraped up and then stirred by the stirring component located on the tank, so that the wastewater in the tank is fully mixed. This avoids uneven mixing of wastewater and chemicals in the acid-base neutralization tank. At the same time, mixing the sediment with the wastewater also helps the submersible pump to discharge the wastewater, and avoids excessive sediment affecting the drainage of the submersible pump.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Please see Figures 1 to 2As shown, an acid-base neutralization tank includes a tank body 1, a drug dilution tank 2, a submersible pump 3, a stirring device 4, and a first power unit 5. The tank body 1 is used to receive wastewater. The drug dilution tank 2, located on one side of the top of the tank body 1, is used to hold the reagent (solid granules or powder, such as solid alkali). By setting up the drug dilution tank 2, the reagent can be pre-diluted to facilitate better mixing of the wastewater and the reagent. In this embodiment, one side of the drug dilution tank 2 is connected to the tank body 1 via a drain pipe 21.

[0024] A submersible pump 3 is fixed at the bottom of the tank 1 and is used to discharge the wastewater after it has been adjusted in the acid-base neutralization tank to the next process, that is, to discharge the adjusted wastewater out of the tank 1. In this embodiment, the output end of the submersible pump 3 is connected to the drug dilution tank 2 and the outside of the tank 1 through pipelines. In this embodiment, the pipelines include a first connecting pipe 6, a second connecting pipe 61, and a third connecting pipe 62. The bottom end of the first connecting pipe 6 is connected to the output end of the submersible pump 3, and the second connecting pipe 61 and the third connecting pipe 62 are respectively connected to the output end of the first connecting pipe 6. The output end of the second connecting pipe 61 extends into the inside of the drug dilution tank 2, and the output end of the third connecting pipe 62 extends into the outside of the tank 1, so that the wastewater in the tank 1 can be discharged to the drug dilution tank 2 or the outside of the tank 1, respectively.

[0025] It should be noted that the second connecting pipe 61 and the third connecting pipe 62 are respectively equipped with solenoid valves 611 as in the prior art, so as to control the flow of wastewater in the neutralization tank (to the outside of the drug dilution tank 2 or the tank body 1) by opening and closing the solenoid valves 611. In practice, when it is necessary to dilute the drug added to the drug dilution tank 2, the solenoid valve 611 of the second connecting pipe 61 is opened and the solenoid valve 611 of the third connecting pipe 62 is closed. At this time, the wastewater in the tank body 1 flows into the drug dilution tank 2 to dilute the drug. The diluted drug can then be discharged into the tank body 1 through the drain pipe 21. At this time, the wastewater in the tank body 1 forms an internal circulation. The submersible pump 3 can suck out the undissolved alkali at the bottom of the tank and discharge it back into the tank body 1 through the drug dilution tank 2, so that the alkali is fully dissolved and the dissolution time is reduced. When it is necessary to discharge the wastewater in the tank body 1 to the outside of the tank body 1, the solenoid valve 611 of the third connecting pipe 62 is opened and the solenoid valve 611 of the second connecting pipe 61 is closed.

[0026] In this embodiment, the upper part of the stirring device 4 is slidably disposed at the top of the tank body 1, and the bottom end of the stirring device 4 extends into the interior of the tank body 1 for stirring the wastewater in the tank body 1. Two slide rails 7 are fixedly spaced at the top of the tank body 1. The stirring device 4 includes a moving component 41 and a stirring component 42. The upper part of the moving component 41 is slidably disposed on the two slide rails 7, and the stirring component 42 is rotatably disposed at the lower part of the moving component 41. A second power unit 43 for driving the stirring component 42 to rotate is fixedly disposed at the top of the moving component 41.

[0027] Specifically, the moving component 41 includes a moving plate 411 and a housing 412. The moving plate 411 is a rectangular plate, and its two ends are slidably mounted on two slide rails 7. The housing 412 is fixed to the bottom surface of the moving plate 411 and is used to support the stirring component 42. The stirring component 42 includes two shafts 421 and multiple stirring rods 422. The two shafts 421 are respectively horizontally arranged on opposite sides of the housing 412, and the axial direction of the two shafts 421 is parallel to the width direction of the tank 1. One end of the two shafts 421 is rotatably connected to the housing 412. There are multiple stirring rods 422, which are evenly fixed on the shafts 421 located outside the housing 412, and are used to stir the wastewater in the tank 1.

[0028] Please see Figure 2 As shown, the second power unit 43 includes a drive rod 432 and a first motor 431. The first motor 431 is fixed to the top of the moving plate 411. The output end of the first motor 431 extends through the moving plate 411 into the interior of the housing 412. The drive rod 432 is vertically arranged inside the housing 412. The top end of the drive rod 432 is fixedly connected to the output end of the first motor 431. Thus, the first motor 431 can drive the drive rod 432 to rotate. The bottom end of the drive rod 432 extends towards the bottom of the housing 412 and is fixedly provided with a first helical gear 433. One end of each of the two shafts 421 passes through the side wall of the housing 412 and extends into the interior of the housing 412. Each shaft is fixedly provided with a second helical gear 434. The two second helical gears 434 mesh with the first helical gear 433 respectively.

[0029] During implementation, the first motor 431 is started, which drives the drive rod 432 to rotate, thereby driving the first helical gear 433 to rotate. At this time, the two second helical gears 434 meshing with the first helical gear 433 rotate simultaneously, thereby driving multiple stirring rods 422 to rotate through the two shafts 421, thereby fully stirring the wastewater in the tank 1 and avoiding uneven mixing of wastewater and reagents in the acid-base neutralization tank.

[0030] In this embodiment, the first power unit 5 is disposed on one side of the pool body 1 and is used to drive the stirring device 4 to move along the length direction of the pool body 1. Specifically, the first power unit 5 includes a lead screw 51 and a second motor 52, wherein the lead screw 51 is rotatably disposed at the top of the pool body 1, the second motor 52 is disposed on one side of the pool body 1, one end of the lead screw 51 is fixedly connected to the output end of the second motor 52, and the other end of the lead screw 51 extends through the moving plate 411 to the other side of the pool body 1, and the lead screw 51 is screwed to the moving plate 411.

[0031] In practice, the first motor 431 of the first power unit 5 is first started to drive the stirring rod 422 to stir the wastewater in the tank 1. Then the second motor 52 of the second power unit 43 is started to rotate forward or reverse, which in turn drives the lead screw 51 fixedly connected to the second motor 52 to rotate forward or reverse. Since the moving plate 411 is slidably set on the two slide rails 7 and screwed to the lead screw 51, the moving plate 411 will move back and forth along the length of the tank 1 during the forward or reverse rotation of the lead screw 51. In this way, the stirring device 4 will move back and forth along the length of the tank 1 to stir the wastewater in the tank 1 more thoroughly.

[0032] In this embodiment, a scraping assembly 8 is fixedly installed at the bottom of the housing 412. Specifically, the scraping assembly 8 includes two spaced-apart support rods 81, the top ends of which are fixedly connected to the bottom of the housing 412, and the bottom ends of which extend toward the bottom surface of the tank 1 and are fixedly provided with scrapers 82, the long axis of which is parallel to the width direction of the tank 1. In practice, while the second power unit 43 drives the stirring device 4 to move back and forth along the length direction of the tank 1, it can drive the sliding plate to scrape up the sediment deposited at the bottom of the tank 1. Then, the sediment is stirred by the stirring assembly 42 located on the housing 412, so that the wastewater in the tank 1 is fully mixed, avoiding uneven mixing of wastewater and chemicals in the tank 2. At the same time, mixing the sediment with the wastewater also helps the submersible pump 3 to discharge the wastewater, preventing excessive sediment from affecting the drainage of the submersible pump 3. Preferably, the scraper 82 has a trapezoidal structure that is narrow at the top and wide at the bottom to facilitate the removal of sediment in the tank 1.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
