Description

Technical Field

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

[0002] Wastewater treatment is the process of removing pollutants from wastewater through physical, chemical, and biological methods, so that it meets environmental standards and can be safely discharged or recycled. It includes methods such as physical filtration, sedimentation, biodegradation, and chemical oxidation. Among these, chemical treatment is a crucial part, which involves adding chemicals to wastewater to react and remove various pollutants and adjust water quality parameters. Before adding chemicals, a chemical mixing device is required.

[0003] For example, Chinese patent application number CN202420723133.0 discloses a wastewater treatment agent mixing device, relating to the field of wastewater treatment technology. It includes a base plate with a side plate installed on both the left and right sides of the upper part of the base plate. A turntable is rotatably connected to the right end of the left side plate, and a right-opening slot assembly is installed on the right end of the turntable. A limiting structure is rotatably connected inside the right side plate, and a fixed base is connected to the right end of the limiting structure via a rotating shaft. This invention only requires pulling out the fixed base, which causes the limiting structure to move away from the right side plate. At this point, the support shaft of the mixing chamber structure will disengage from the limiting structure. Then, the mixing chamber structure can be pulled out to the right for removal. Compared to flange and bolt connections, the disassembly and installation process is much more convenient and faster.

[0004] However, in actual use, the above-mentioned device is used to stir the wastewater treatment agent for a long time, and the agent crystals are easy to form on its inner wall. If these crystals are not cleaned, they can affect the effect of re-mixing and using the agent, and at the same time, they will cause waste of the agent. Utility Model Content

[0016] Compared with the prior art, the present invention provides a wastewater treatment agent mixing device, which has the following beneficial effects:

[0017] 1. This utility model uses the rotation of a threaded rod to drive the lifting ring frame on it to rise and fall along the thread of the lifting ring frame. At the same time, the lifting ring frame slides up and down along a limiting rod to limit the movement of the lifting ring frame. This allows the lifting ring frame to drive the bottom of the scraper ring to scrape off the crystals generated on the inner wall of the mixing cylinder during the descent. The crystals are scraped down to the bottom of the mixing cylinder and discharged from the discharge port, thereby cleaning the crystals on the inner wall of the mixing cylinder, preventing the crystals from affecting the overall mixing effect of the reagent, facilitating cleaning, and reducing the labor intensity of the workers.

[0018] 2. This utility model uses two connecting rods to rotate, which in turn drives the rotating rod, mixing rod, and scraper to rotate. The scraper scrapes up the precipitated agent at the bottom of the mixing cylinder for mixing, thereby preventing the added agent from settling. This ensures that the wastewater treatment agent added to the mixing cylinder is fully and comprehensively stirred and mixed, improving the mixing efficiency and ensuring the mixing effect.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown in Figure 1, this utility model provides a wastewater treatment agent mixing device, including a support base 1, a mixing cylinder 2 fixedly mounted on the top of the support base 1, a top box 3 fixedly mounted on the top of the mixing cylinder 2, connecting pipes 6 fixedly mounted on both sides of the top box 3, the bottom end of the connecting pipes 6 penetrating the bottom of the top box 3 and extending to the top of the mixing cylinder 2, an agent cylinder 7 fixedly mounted on the top of the connecting pipes 6, and an electric valve 8 fixedly mounted on the connecting pipes 6 for easy adjustment of the electric valve 8 to control the agent flow rate, a discharge port opened at the bottom of the mixing cylinder 2, a rotating bottom cover 12 connected to the inner wall of the discharge port by threads, a discharge pipe 11 fixedly mounted on one side of the bottom of the mixing cylinder 2, and both the discharge pipe 11 and the rotating bottom cover 12 are located inside the support base 1 for easy discharge of crystallized and mixed wastewater treatment agents, a control panel 10 for controlling the operation of the electric valve 8 fixedly mounted on the front side of the support base 1, and a box cover 9 connected to the center of the top of the top box 3 by a hinge.

[0029] like Figure 1-4 As shown, the mixing cylinder 2 is equipped with a wall scraping assembly 5 for scraping away crystals generated on the inner wall of the mixing cylinder 2. The wall scraping assembly 5 includes a threaded rod 51, the top and bottom of which are connected by bearings between the top and bottom of the mixing cylinder 2. A lifting ring frame 52 is threadedly connected to the threaded rod 51 and is located at the top of the mixing cylinder 2. A scraping ring 53 is fixedly provided at the bottom of the lifting ring frame 52 and contacts the inner wall of the mixing cylinder 2, facilitating the scraping ring 53 to descend and scrape away the crystals on the inner wall of the mixing cylinder 2. A limiting rod 54 is provided through the center of the rear side of the lifting ring frame 52, and the top and bottom of the limiting rod 54 are fixedly provided at the top and bottom of the mixing cylinder 2, respectively. A second motor 55 is fixedly provided at the center of the top box 3. The output shaft of the second motor 55 passes through the bottom of the top box 3 and is fixedly connected to the top of the threaded rod 51, facilitating the second motor 55 to drive the threaded rod 51 to rotate. The second motor 55 is controlled by the control panel 10.

[0030] By setting up the wall scraping component 5, when the inner wall of the mixing drum 2 needs to be cleaned after long-term use, the control panel 10 controls the second motor 55 inside the top box 3 to work. The second motor 55 drives the threaded rod 51 to rotate. The rotation of the threaded rod 51 drives the lifting ring frame 52 on it to rise and fall along the thread of the lifting ring frame 52. At the same time, the lifting ring frame 52 slides up and down along the limit rod 54 to limit the movement of the lifting ring frame 52. During the descent, the lifting ring frame 52 drives the bottom of the scraper ring 53 to scrape off the crystals generated on the inner wall of the mixing drum 2. The crystals are scraped off to the bottom of the mixing drum 2. Then, by rotating the bottom cover 12, the scraped crystals are discharged through the discharge port, thereby cleaning the crystals on the inner wall of the mixing drum 2, avoiding the crystals from affecting the overall mixing effect of the agent, facilitating cleaning, and reducing the labor intensity of the workers.

[0031] like Figure 1-3 As shown in Figure 5, the mixing cylinder 2 is equipped with a mixing component 4 for uniformly mixing wastewater treatment agents. The mixing component 4 includes two connecting rods 46. The top ends of the two connecting rods 46 are connected to the top of the mixing cylinder 2 via bearings. The two connecting rods 46 are respectively located on both sides of the threaded rod 51. The top ends of the two connecting rods 46 penetrate the top box 3 and are connected to the top of the top of the top box 3 via bearings. The bottom of the connecting rod 46 is provided with a rotating rod 41, and the bottom end of the rotating rod 41 contacts the center of the bottom of the mixing cylinder 2. Several evenly distributed mixing rods 42 are fixed on the rotating rod 41. The bottom end of the connecting rod 46 is threaded with a bolt for fixing the connecting rod 46 and the rotating rod 41, so that the rotating rod 41 at the bottom end of the connecting rod 46 can be disassembled by means of bolts.

[0032] The mixing rod 42 is located inside the mixing cylinder 2, which facilitates the rotation of the two connecting rods 46 to drive the rotating rod 41 and several mixing rods 42 thereon to rotate. Gears 43 are fixedly provided on the top ends of the two connecting rods 46, and the two gears 43 mesh with each other. A first motor 44 is fixedly provided on one side of the top of the top box 3. The output shaft of the first motor 44 passes through the top of the top box 3 and is fixedly connected to the top end of one of the connecting rods 46, which facilitates the first motor 44 to drive one of the connecting rods 46 to rotate. Several evenly distributed scraper rods 45 are fixedly provided at the bottom end of the rotating rod 41, and the bottom of the scraper rods 45 contacts the bottom end of the mixing cylinder 2, which facilitates the scraper rods 45 to scrape up the medicine settled at the bottom end of the mixing cylinder 2 for mixing, and at the same time facilitates subsequent discharge. The first motor 44 is controlled by the control panel 10.

[0033] By setting up the mixing component 4, the wastewater treatment agent to be mixed is added to two agent cylinders 7. Then, the rotating rod 41 is fixed to the bottom of the connecting rod 46 with bolts, which facilitates the disassembly of the rotating rod 41 for maintenance or replacement. Then, the control panel 10 controls the first motor 44 to work, and at the same time controls the two electric valves 8 to open, so that the agent inside the agent cylinder 7 flows into the mixing cylinder 2 through the connecting pipe 6. Then, the first motor 44 drives the connecting rod 46 to rotate, and drives the two gears 43 to mesh and rotate. The rotating gears 43 drive the two connecting rods 46 to rotate in opposite directions. The rotation of the connecting rod 46 drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the several mixing rods 42 and scraper 45 on it to rotate. The scraper 45 scrapes up the agent that has settled at the bottom of the mixing cylinder 2 for mixing, thereby avoiding the sedimentation of the added agent. The wastewater treatment agent added to the mixing cylinder 2 is thoroughly and comprehensively mixed. Finally, the agent can be discharged by opening the discharge pipe 11, which improves the mixing efficiency and ensures the mixing effect.
