Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing device for wastewater treatment. Background Technology

[0002] The development of industry has driven the rapid development of related industries, but at the same time it has damaged the natural environment, especially the serious pollution of water sources. It is necessary to protect water sources and treat sewage. Nowadays, sewage treatment mainly involves adding chemicals to separate heavy metal ions and impurities from sewage and adjusting the pH value of the water to the normal range. Therefore, chemical dosing devices are often used in sewage treatment.

[0003] According to Chinese patent CN213506022U, a dosing device for sewage treatment can be used to stir the chemical solution by driving a first rotating rod with a motor to make the first stirring blade stir the chemical solution. At the same time, the driving gear drives the driven gear to rotate, which causes the second rotating rod to drive the second stirring blade to rotate, so that the chemical solution is stirred more thoroughly.

[0004] However, there are still some shortcomings in this patent. In this device, the drug solution is fully stirred and mixed during the rotation of the first and second stirring blades. However, during the stirring process, the first and second stirring blades easily splash some of the drug solution, causing some of the drug solution to adhere to the inner wall of the shell. This can easily result in some of the drug solution not being fully mixed, affecting the stirring effect of the device. Therefore, we propose a dosing device for sewage treatment. Summary of the Invention

[0005] The purpose of this invention is to provide a dosing device for wastewater treatment, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dosing device for sewage treatment, comprising an installation plate and a stirring assembly disposed above the installation plate. The stirring assembly includes a stirring tank disposed above the installation plate. A feed hopper is connected to the top right side of the stirring tank. A first drive motor is fixedly connected to the top of the stirring tank. A first output shaft is fixedly connected to the output end of the first drive motor. The outer wall of the first output shaft is rotatably connected to the inner wall of the top of the stirring tank via a bearing. A stirring frame is fixedly connected to the bottom outer wall of the first output shaft. A rotating rod is rotatably connected to the top of the inner wall of the stirring frame via a bearing. A rotating plate is fixedly connected to the outer wall of the rotating rod. A scraper is fixedly connected to the side wall of the stirring frame. The side wall of the scraper is slidably connected to the inner wall of the stirring tank. By setting up the stirring assembly, the stirring frame can be rotated to achieve thorough mixing of sewage and chemical solution, thereby improving the sewage treatment effect of the device.

[0007] Preferably, the stirring assembly further includes a connecting pipe disposed on the right side of the bottom of the stirring tank, and a pump body disposed on the other end of the connecting pipe. The bottom of the pump body is fixedly connected to the top of the mounting plate, and a drain pipe is disposed on the output end of the pump body. After the chemical solution and sewage are treated, the operator turns on the pump body to cause the pump body to draw the treated sewage into the pump body through the connecting pipe and discharge it through the drain pipe.

[0008] Preferably, the bottom of the mounting plate is further provided with a vibration assembly. The vibration assembly includes a support frame fixedly connected to the bottom of the mounting plate. A second drive motor is fixedly connected to the inner wall of the bottom of the support frame. A second output shaft is fixedly connected to the output end of the second drive motor. The outer wall of the middle part of the second output shaft is rotatably connected to the inner wall of the mounting plate through a bearing. A circular plate is fixedly connected to the top of the second output shaft. The bottom of the circular plate is slidably connected to the top of the mounting plate. A first semicircular block is fixedly connected to the top of the circular plate. A second semicircular block is slidably connected to the top of the first semicircular block. The top of the second semicircular block is fixedly connected to the bottom of the mixing tank. A limit block is fixedly connected to the outer wall of the mixing tank. A limit post is slidably connected to the inner wall of the limit block. The bottom of the limit post is fixedly connected to the top of the mounting plate. An annular block is fixedly connected to the outer wall of the middle part of the limit post. A spring is fixedly connected to the top of the annular block. The other end is fixedly connected to the bottom of the limiting block. By setting a vibration component, during the mixing of sewage and medicine, in order to prevent some medicine from adhering to the inner wall of the mixing tank and affecting the mixing effect with sewage, the operator turns on the second drive motor to make the second output shaft rotate. During the rotation of the second output shaft, the circular plate will rotate, and during the rotation of the circular plate, the first semicircular block will rotate, causing the first semicircular block to squeeze the second semicircular block. This causes the mixing tank to move upward along the outer wall of the limiting column through the limiting block. When the first semicircular block stops squeezing the second semicircular block, under the action of the mixing tank's own weight, it is easy to move downward along the outer wall of the limiting column through the limiting block and squeeze the spring. This process is repeated to make the mixing tank vibrate up and down, thereby making it easier to shake off the medicine adhering to the inner wall of the mixing tank and improve the mixing effect of sewage and medicine.

[0009] Preferably, four rollers are fixedly connected to the bottom of the mounting plate. The four rollers are equidistantly fixed to the four corners of the bottom of the mounting plate. By setting four rollers at the bottom of the mounting plate, it is convenient for operators to move the device.

[0010] Preferably, a push rod is fixedly connected to the top left side of the mounting plate. The push rod is located on the left side of the mixing tank. By setting the push rod, it is convenient for the operator to move the device by pushing the push rod.

[0011] Preferably, there are three stirring racks, all of equal size, and the three stirring racks are arranged in a circular array along the central axis of the first output shaft.

[0012] Preferably, one side of the scraper is slidably connected to the inner wall of the mixing tank, and the other side of the scraper is fixedly connected to the outer wall of the mixing frame. By setting a scraper inside the mixing tank, it is convenient to scrape off the liquid on the inner wall of the mixing tank, thereby improving the treatment effect of the device on sewage.

[0013] Preferably, the first semicircular block and the second semicircular block are of the same size, and the top of the first semicircular block and the bottom of the second semicircular block are slidably connected. By setting the first semicircular block and the second semicircular block, it is convenient to squeeze the second semicircular block through the first semicircular block, thereby causing the mixing tank to vibrate up and down.

[0014] This invention provides a dosing device for wastewater treatment. This wastewater treatment dosing device has the following beneficial effects:

[0015] (1) The dosing device for sewage treatment is equipped with a stirring component. When sewage needs to be treated, the operator feeds the sewage and the chemical solution into the inside of the stirring tank through the feed hopper. Then, the first drive motor is turned on to make the first output shaft rotate. During the rotation of the first output shaft, the stirring frame will rotate. During the rotation of the stirring frame, the sewage and the chemical solution will be fully stirred and mixed. During the stirring process, the operator can continuously add the chemical solution through the feed hopper. When the stirring frame rotates, the rotating rod will rotate, thereby causing the rotating plate to rotate, which improves the mixing effect of the sewage and the chemical solution inside the stirring tank. During the rotation of the stirring frame, the scraper will rotate, which makes it easier to scrape off the chemical solution adhering to the inner wall of the stirring tank during the stirring process, thereby improving the mixing effect of the device on the sewage and the chemical solution and improving the sewage treatment effect. After the chemical solution and sewage are treated, the operator turns on the pump body to make the pump body pump the treated sewage into the pump body through the connecting pipe and discharge it through the drain pipe.

[0016] (2) The dosing device for sewage treatment is equipped with a vibration component. During the process of mixing sewage and chemical solution, in order to avoid some chemical solution adhering to the inner wall of the mixing tank and affecting the mixing effect with sewage, the operator turns on the second drive motor to make the second output shaft rotate. During the rotation of the second output shaft, the circular plate will rotate. During the rotation of the circular plate, the first semicircular block will rotate, causing the first semicircular block to squeeze the second semicircular block. This causes the mixing tank to move upward along the outer wall of the limiting column through the limiting block. When the first semicircular block stops squeezing the second semicircular block, under the action of the mixing tank's own weight, it is easy to move downward along the outer wall of the limiting column through the limiting block and squeeze the spring. This process is repeated to make it easy to make the mixing tank vibrate up and down, thereby making it easy to shake off the chemical solution adhering to the inner wall of the mixing tank and improve the mixing effect of sewage and chemical solution.

Detailed Implementation

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] A preferred embodiment of the dosing device for wastewater treatment provided by this utility model is, for example...Figures 1 to 5 As shown: A dosing device for wastewater treatment includes a mounting plate 1 and a stirring assembly 41 disposed above the mounting plate 1. The stirring assembly 41 includes a stirring tank 411 disposed above the mounting plate 1. A feed hopper 413 is connected to the top right side of the stirring tank 411. A first drive motor 412 is fixedly connected to the top of the stirring tank 411. A first output shaft 414 is fixedly connected to the output end of the first drive motor 412. The outer wall of the first output shaft 414 is rotatably connected to the inner top wall of the stirring tank 411 via a bearing. A stirring frame 415 is fixedly connected to the bottom outer wall of the first output shaft 414. A rotating rod 416 is rotatably connected to the top of the inner wall of the stirring frame 415 via a bearing. A rotating plate 417 is fixedly connected to the outer wall of the rotating rod 416. A scraper 418 is fixedly connected to the side wall of the stirring frame 415. The side wall of the scraper 418 is slidably connected to the inner wall of the stirring tank 411. By setting up the stirring assembly 41, when wastewater needs to be treated, the device can be operated... Personnel feed wastewater and chemicals into the mixing tank 411 through the feed hopper 413. Then, by activating the first drive motor 412, the first output shaft 414 rotates. This rotation causes the mixing frame 415 to rotate, ensuring thorough mixing of the wastewater and chemicals. During this mixing process, the operator can continuously add chemicals through the feed hopper 413. The rotation of the mixing frame 415 causes the rotating rod 416 to rotate, which in turn causes the rotating plate 417 to rotate, further improving the mixing effect of the wastewater and chemicals inside the mixing tank 411. The rotation of the mixing frame 415 also causes the scraper 418 to rotate, allowing the scraper to remove any chemicals adhering to the inner wall of the mixing tank 411 during the mixing process. This enhances the mixing effect of the wastewater and chemicals, thereby improving the wastewater treatment efficiency.

[0025] The stirring assembly 41 also includes a connecting pipe 419 connected to the bottom right side of the stirring tank 411. The other end of the connecting pipe 419 is connected to a pump body 4110. The bottom of the pump body 4110 is fixedly connected to the top of the mounting plate 1. The output end of the pump body 4110 is connected to a drain pipe 4111. After the chemical solution and sewage are treated, the operator turns on the pump body 4110 to cause the pump body 4110 to draw the treated sewage into the interior of the pump body 4110 through the connecting pipe 419 and discharge it through the drain pipe 4111.

[0026] A preferred embodiment of the dosing device for wastewater treatment provided by this utility model is, for example... Figures 1 to 5As shown: A vibration assembly 42 is also provided at the bottom of the mounting plate 1. The vibration assembly 42 includes a support frame 421 fixedly connected to the bottom of the mounting plate 1. A second drive motor 422 is fixedly connected to the inner wall of the bottom of the support frame 421. A second output shaft 423 is fixedly connected to the output end of the second drive motor 422. The outer wall of the middle part of the second output shaft 423 is rotatably connected to the inner wall of the mounting plate 1 through a bearing. A circular plate 424 is fixedly connected to the top of the second output shaft 423. The bottom of the circular plate 424 is slidably connected to the top of the mounting plate 1. The top of the circular plate 424 is fixed. A first semicircular block 425 is connected, and a second semicircular block 426 is slidably connected to the top of the first semicircular block 425. The top of the second semicircular block 426 is fixedly connected to the bottom of the mixing tank 411. A limit block 427 is fixedly connected to the outer wall of the mixing tank 411. A limit post 428 is slidably connected to the inner wall of the limit block 427. The bottom of the limit post 428 is fixedly connected to the top of the mounting plate 1. An annular block 429 is fixedly connected to the outer wall of the middle part of the limit post 428. A spring 4210 is fixedly connected to the top of the annular block 429. The other end of the spring 4210 is connected to the limit post 429. The bottom of block 427 is fixedly connected. By setting a vibration component 42, during the mixing of sewage and medicine, in order to prevent some medicine from adhering to the inner wall of the mixing tank 411 and affecting the mixing effect with sewage, the operator turns on the second drive motor 422 to cause the second output shaft 423 to rotate. During the rotation of the second output shaft 423, the circular plate 424 will rotate. During the rotation of the circular plate 424, the first semicircular block 425 will rotate, causing the first semicircular block 425 to rotate against the second semicircular block 426. The mixing drum 411 is squeezed, causing it to move upward along the outer wall of the limiting post 428 via the limiting block 427. When the first semicircular block 425 stops squeezing the second semicircular block 426, the mixing drum 411 moves downward along the outer wall of the limiting post 428 via the limiting block 427 under its own weight, and squeezes the spring 4210. This process is repeated to make the mixing drum 411 vibrate up and down, thereby making it easier to shake off the liquid medicine attached to the inner wall of the mixing drum 411 and improve the mixing effect of sewage and liquid medicine.

[0027] Furthermore, four rollers 3 are fixedly connected to the bottom of the mounting plate 1. The four rollers 3 are equidistantly fixed to the four corners of the bottom of the mounting plate 1. By setting four rollers 3 at the bottom of the mounting plate 1, it is convenient for operators to move the device.

[0028] Furthermore, a push rod 2 is fixedly connected to the top left side of the mounting plate 1. The push rod 2 is located on the left side of the mixing tank 411. By setting the push rod 2, it is convenient for the operator to move the device by pushing the push rod 2.

[0029] Furthermore, there are three stirring racks 415, all of equal size, and the three stirring racks 415 are arranged in a circular array along the central axis of the first output shaft 414.

[0030] Furthermore, one side of the scraper 418 is slidably connected to the inner wall of the mixing tank 411, and the other side of the scraper 418 is fixedly connected to the outer wall of the mixing frame 415. By setting the scraper 418 inside the mixing tank 411, it is convenient to scrape the liquid on the inner wall of the mixing tank 411 through the scraper 418, thereby improving the treatment effect of the device on sewage.

[0031] In addition, the first semicircular block 425 and the second semicircular block 426 are the same size, and the top of the first semicircular block 425 is slidably connected to the bottom of the second semicircular block 426. By setting the first semicircular block 425 and the second semicircular block 426, it is convenient to squeeze the second semicircular block 426 through the first semicircular block 425, thereby causing the mixing tank 411 to vibrate up and down.

[0032] Working Principle: When wastewater needs treatment, the operator feeds the wastewater and chemical solution into the mixing tank 411 through the feed hopper 413. Then, by turning on the first drive motor 412, the first output shaft 414 rotates. During the rotation of the first output shaft 414, the mixing frame 415 rotates, achieving thorough mixing of the wastewater and chemical solution. During the mixing process, the operator can continuously add chemical solution through the feed hopper 413. As the mixing frame 415 rotates, it generates its own rotation through the rotating rod 416, thereby promoting... The rotating plate 417 rotates to improve the mixing effect of sewage and medicine inside the mixing tank 411. During the rotation of the mixing frame 415, the scraper 418 will rotate, which will facilitate the scraping of the medicine adhering to the inner wall of the mixing tank 411 during the mixing process. This improves the mixing effect of sewage and medicine and the treatment effect of sewage. After the medicine and sewage are treated, the operator turns on the pump body 4110 to pump the treated sewage into the pump body 4110 through the connecting pipe 419 and discharge it through the drain pipe 4111.

[0033] During the mixing of wastewater and chemical solution, to prevent some chemical solution from adhering to the inner wall of the mixing tank 411 and affecting the mixing effect with the wastewater, the operator activates the second drive motor 422, causing the second output shaft 423 to rotate. The rotation of the second output shaft 423 causes the circular plate 424 to rotate, which in turn causes the first semicircular block 425 to rotate. This causes the first semicircular block 425 to press against the second semicircular block 426, thus accelerating the mixing of wastewater and chemical solution in the mixing tank 411. 1. The limiting block 427 moves upward along the outer wall of the limiting post 428. When the first semicircular block 425 no longer squeezes the second semicircular block 426, under the action of the weight of the mixing tank 411 itself, it is easy to move downward along the outer wall of the limiting post 428 through the limiting block 427 and squeeze the spring 4210. Repeating this process makes it easy to make the mixing tank 411 vibrate up and down, thereby making it easy to shake off the liquid medicine attached to the inner wall of the mixing tank 411 and improve the mixing effect of sewage and liquid medicine.

[0034] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
