Description

Technical Field

[0001] This utility model belongs to the field of oxadiazon production technology, and specifically relates to an aluminum trichloride acidic wastewater treatment device for oxadiazon production. Background Technology

[0002] Oxalide is a selective pre-emergence herbicide mainly used in rice, soybean, and cotton fields. It controls annual grasses and broadleaf weeds by inhibiting photosynthesis or cell division. It is chemically stable, but its production often involves chlorination and condensation reactions, and may use aluminum trichloride as a catalyst or reaction medium, resulting in wastewater containing high concentrations of aluminum trichloride and acidic pollutants.

[0003] The common treatment process for acidic aluminum trichloride wastewater generated during production involves wastewater collection, neutralization reaction (pH adjusted to 6-8), flocculation and sedimentation, solid-liquid separation, sludge dewatering, and clean water discharge / reuse. During the neutralization reaction, alkaline agents (such as lime or sodium hydroxide) are added to neutralize the acidic wastewater, generating aluminum hydroxide precipitate. This results in a large amount of aluminum hydroxide sludge forming inside the reaction tank, which settles at the bottom and is inconvenient for workers to handle.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a treatment device for acidic wastewater of aluminum trichloride used in the production of oxadiazon, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a treatment device for acidic wastewater from aluminum trichloride production of oxadiazon, comprising a reaction tank, with several inlet pipes and a displacement assembly arranged on the outer surface of the reaction tank, a lifting assembly arranged on the top of the displacement assembly, a cleaning assembly arranged on the bottom of the lifting assembly, and an auxiliary assembly arranged on the outer surface of the lifting assembly. The displacement assembly is used to drive the lifting assembly and the cleaning assembly to move along the reaction tank, and the lifting assembly is used to drive the cleaning assembly to move up and down.

[0007] Furthermore, the displacement assembly includes a slide rail, an electric slider is slidably connected to the outer surface of the slide rail, a baffle is fixedly connected to the end of the slide rail, and both the slide rail and the baffle are fixedly installed on the top of the reaction tank.

[0008] Furthermore, the lifting assembly includes a support column, which is fixedly installed on the top of the electric slider. An electric push rod is fixedly connected inside the support column, and a sliding column is fixedly connected to the upper end of the electric push rod. A crossbar is fixedly installed at the upper end of the sliding column.

[0009] Furthermore, the decontamination assembly includes a connecting rod, which is fixedly connected to the bottom of the crossbar. A rotating shaft is rotatably connected to the outer surface of the connecting rod, and a decontamination hopper is rotatably connected to the outer surface of the rotating shaft. A screen is fixedly connected to the outer surface of the decontamination hopper.

[0010] Furthermore, the auxiliary component includes a connecting frame, which is fixedly installed on the outer surface of the support column. A pin is rotatably connected to the outer surface of the connecting frame, and a pulley is rotatably connected to the connecting frame via the pin.

[0011] Furthermore, a support is fixedly installed on the top of the reaction tank, and the support is fixedly connected to the water inlet pipe.

[0012] Furthermore, the outer surface of the support column is fixedly connected with ribs, and the outer surface of the support column is threaded with bolts. The support column is fixedly installed on the top of the electric slider by bolts.

[0013] This utility model has the following beneficial effects: This invention connects a lifting component and a cleaning component. When the displacement component moves the lifting component along the reaction tank, the cleaning component on the lifting component moves accordingly. The cleaning component moves along the bottom of the reaction tank, scraping away the aluminum hydroxide sludge at the bottom of the tank, leaving the sludge on the cleaning component. Then, the lifting component moves the cleaning component upwards along the inside of the reaction tank until it rises out of the tank. At this point, the inner wall of the reaction tank no longer restricts the cleaning component, and it rotates and tilts under the pressure of the auxiliary component and gravity, thus emptying the aluminum hydroxide sludge. This reduces the labor intensity of the workers and is convenient to use.

[0014] This utility model connects a sludge removal hopper and a screen. The sludge removal hopper is equipped with a front slope and two sets of ramps. The front slope of the sludge removal hopper facilitates the scooping up of aluminum hydroxide sludge from the reaction tank, while the two sets of ramps on the sludge removal hopper facilitate water flow, allowing the water carried by the sludge removal hopper to pass through the screen and return to the reaction tank, thereby achieving solid-liquid separation and facilitating subsequent processes.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-8 As shown, this utility model is a device for treating acidic wastewater of aluminum trichloride used in the production of oxadiazon, including a reaction tank 1. The outer surface of the reaction tank 1 is provided with several inlet pipes 2 and a displacement component 3. The top of the displacement component 3 is provided with a lifting component 4, the bottom of the lifting component 4 is provided with a cleaning component 5, and the outer surface of the lifting component 4 is provided with an auxiliary component 6. The displacement component 3 is used to drive the lifting component 4 and the cleaning component 5 to move along the reaction tank 1, and the lifting component 4 is used to drive the cleaning component 5 to move up and down.

[0022] Several inlet pipes 2 are used to inject acidic wastewater of aluminum trichloride, alkaline wastewater from alkaline agents or other processes into the reaction tank 1 for mixing. Aluminum hydroxide is generated in the reaction tank 1. The displacement component 3 is activated to move the lifting component 4. The lifting component 4 moves the cleaning component 5 along the bottom of the reaction tank 1. During the movement, the cleaning component 5 can scrape off the aluminum hydroxide sludge at the bottom of the reaction tank 1. After moving to one side of the reaction tank 1, the lifting component 4 is activated. The lifting component 4 moves the cleaning component 5 upward along the inner wall of the reaction tank 1 until the cleaning component 5 rises from the reaction tank 1. The cleaning component 5 is then squeezed by the auxiliary component 6 and subjected to gravity, causing the cleaning component 5 to rotate. At this time, the aluminum hydroxide sludge on the cleaning component 5 can slide off the cleaning component 5, reducing the labor intensity of the workers and making cleaning more convenient.

[0023] This invention connects the lifting assembly 4 and the cleaning assembly 5. When the displacement assembly 3 moves the lifting assembly 4 along the reaction tank 1, the cleaning assembly 5 on the lifting assembly 4 can move accordingly. The cleaning assembly 5 moves along the bottom of the reaction tank 1, scraping away the aluminum hydroxide sludge at the bottom of the reaction tank 1, leaving the sludge on the cleaning assembly 5. Then, the lifting assembly 4 moves the cleaning assembly 5 upward along the inside of the reaction tank 1 until the cleaning assembly 5 rises from the inside of the reaction tank 1. The inner wall of the reaction tank 1 no longer limits the cleaning assembly 5. Under the squeezing of the auxiliary assembly 6 and the action of gravity, the cleaning assembly 5 rotates and tilts, thereby pouring out the aluminum hydroxide sludge, reducing the labor intensity of the workers and making it more convenient to use.

[0024] In one embodiment, the displacement component 3 includes a slide rail 301, an electric slider 302 is slidably connected to the outer surface of the slide rail 301, and a baffle 303 is fixedly connected to the end of the slide rail 301. Both the slide rail 301 and the baffle 303 are fixedly installed on the top of the reaction tank 1.

[0025] There are two sets of slide rails 301, which are located on both sides of the cavity of reaction tank 1. Each set of slide rails 301 has two sets of baffles 303. When the electric slider 302 is activated, the electric slider 302 can move along the slide rail 301. The baffles 303 on the slide rail 301 limit the movement distance of the electric slider 302 to prevent the electric slider 302 from falling off the slide rail 301.

[0026] In one embodiment, the lifting assembly 4 includes a support column 401, which is fixedly installed on the top of the electric slider 302. An electric push rod 402 is fixedly connected inside the support column 401. A sliding column 403 is fixedly connected to the upper end of the electric push rod 402. A crossbar 404 is fixedly installed at the upper end of the sliding column 403.

[0027] The electric slider 302 drives the support column 401 to move. The support column 401 drives the electric push rod 402, the sliding column 403 and the crossbar 404 to move synchronously. When the electric push rod 402 is activated, the movable end of the electric push rod 402 drives the sliding column 403 and the crossbar 404 to move up and down. The electric push rod 402 is located inside the support column 401, and the support column 401 can protect the electric push rod 402.

[0028] In one embodiment, the above-mentioned cleaning component 5 includes a connecting rod 501, which is fixedly connected to the bottom of the crossbar 404. A rotating shaft 502 is rotatably connected to the outer surface of the connecting rod 501. A cleaning hopper 503 is rotatably connected to the outer surface of the rotating shaft 502. A screen 504 is fixedly connected to the outer surface of the cleaning hopper 503.

[0029] The crossbar 404 drives the connecting rod 501 to move, and the connecting rod 501 drives the sludge removal hopper 503 to move through the rotating shaft 502. When the sludge removal hopper 503 is attached to the bottom of the reaction tank 1, the sludge removal hopper 503 cannot rotate through the rotating shaft 502. At this time, the sludge removal hopper 503 can remove the aluminum hydroxide sludge at the bottom of the reaction tank 1 during the movement. The sludge removal hopper 503 is provided with multiple slopes. When the crossbar 404 drives the sludge removal hopper 503 to move upward, the sludge removal hopper 503 abuts against the inner wall of the reaction tank. At this time, the sludge removal hopper 503 still cannot rotate. The water carried by the sludge removal hopper 503 passes through the screen 504 and returns to the reaction tank 1 under the action of the slope, realizing solid-liquid separation. Until the sludge removal hopper 503 rises from the reaction tank 1, the sludge removal hopper 503 rotates and tilts through the rotating shaft 502, and the aluminum hydroxide sludge can slide off the sludge removal hopper 503.

[0030] In one embodiment, the auxiliary component 6 includes a connecting frame 601, which is fixedly installed on the outer surface of the support column 401. A pin 602 is rotatably connected to the outer surface of the connecting frame 601, and a pulley 603 is rotatably connected to the connecting frame 601 via the pin 602.

[0031] During the upward movement, the sludge hopper 503 comes into contact with the pulley 603. The back of the sludge hopper 503 is sloped so that the pulley 603 can push the sludge hopper 503 to rotate through the rotating shaft 502.

[0032] In one embodiment, for the above-mentioned reaction tank 1, a support 7 is fixedly installed on the top of the reaction tank 1, and the support 7 is fixedly connected to the water inlet pipe 2.

[0033] In one embodiment, for the aforementioned support column 401, a rib plate 8 is fixedly connected to the outer surface of the support column 401, and a bolt 9 is threadedly connected to the outer surface of the support column 401. The support column 401 is fixedly installed on the top of the electric slider 302 by the bolt 9.

[0034] The support 7 is fixedly installed on the reaction tank 1 by bolts 9. The bolts 9 ensure connection stability while facilitating disassembly and maintenance of various components by staff.

[0035] Through the above technical solution, 1. By connecting the lifting assembly 4 and the cleaning assembly 5, when the displacement assembly 3 drives the lifting assembly 4 to move along the reaction tank 1, the cleaning assembly 5 on the lifting assembly 4 can move accordingly. The cleaning assembly 5 moves along the bottom of the reaction tank 1, which can scrape off the aluminum hydroxide sludge at the bottom of the reaction tank 1, leaving the sludge on the cleaning assembly 5. Then, the lifting assembly 4 drives the cleaning assembly 5 to move upward along the inside of the reaction tank 1 until the cleaning assembly 5 rises from the inside of the reaction tank 1. After that, the inner wall of the reaction tank 1 no longer limits the cleaning assembly 5, and the cleaning assembly 5 can move upward in an auxiliary manner. 1. The auxiliary component 6 rotates and tilts under the squeezing and gravity, thereby pouring out the aluminum hydroxide sludge, reducing the labor intensity of the staff and making it more convenient to use; 2. Through the connection of the sludge removal hopper 503 and the screen 504, the sludge removal hopper 503 is equipped with a front slope and two sets of ramps. The front slope of the sludge removal hopper 503 makes it easy to scoop up the aluminum hydroxide sludge in the reaction tank 1, and the two sets of ramps on the sludge removal hopper 503 facilitate the flow of water, so that the water carried by the sludge removal hopper 503 can pass through the screen 504 and return to the reaction tank 1, thereby realizing solid-liquid separation and facilitating the subsequent other processes.
