Description

Technical Field

[0001] This utility model belongs to the field of polyaluminum chloride production and processing technology, specifically a pretreatment device for aluminum trichloride mother liquor. Background Technology

[0002] The main function of polyaluminum chloride (PAC) is to aggregate pollutants such as suspended solids and colloidal substances in water into larger particles, thereby purifying and clarifying the water. Its production usually uses aluminum trichloride aqueous solution as raw material. However, aluminum trichloride aqueous solution contains a small amount of organic matter, which makes it difficult to effectively control the production process parameters of PAC and affect product quality. Therefore, it is necessary to design a special pretreatment device to treat the wastewater in a targeted manner to degrade the raw materials in the wastewater and improve the effectiveness and rationality of wastewater reuse.

[0003] However, the following problems were found in the implementation of the relevant technology: Although the existing device can remove organic matter from aluminum trichloride solution, the mixing efficiency between the treatment agent and the solution is not high enough, resulting in a long time for removing organic matter. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a pretreatment device for aluminum trichloride mother liquor. The device rotates and dispenses the treatment agent simultaneously, allowing it to be evenly sprayed onto the solution. This accelerates the mixing and reaction between the treatment agent and the solution, and has the advantage of processing organic matter in aluminum trichloride solution in a short time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for aluminum trichloride mother liquor, comprising a base plate and a pretreatment tank installed on top of the base plate. An installation column is installed on one side of the top of the base plate, and an installation plate is installed on the top of the installation column. A motor is connected to one side of the bottom of the installation plate, and the output end of the motor is connected to a turntable located inside the pretreatment tank. Two sets of material barrels are symmetrically inserted into the top of the turntable, and a cover plate is hinged to the top of the material barrels. A discharge pipe is inserted into the bottom of the material barrels, and a control valve is installed on the discharge pipe. A rotating rod is connected to the center of the bottom of the turntable, and multiple stirring rods are evenly connected to the side wall of the rotating rod. An inlet pipe is inserted into the upper part of one side wall of the pretreatment tank.

[0006] Preferably, a drain pipe is inserted into the bottom of one side wall of the pretreatment tank, and a flange is welded to the end of the drain pipe away from the pretreatment tank.

[0007] Preferably, a blocking plate is hinged to the lower part of one side wall of the pretreatment box, and a rubber layer is bonded to the connection between the blocking plate and the pretreatment box. A locking buckle is installed between the blocking plate and the corresponding side of the pretreatment box.

[0008] Preferably, the stirring rod has a rectangular structure, and the side wall of the stirring rod has multiple through holes arranged in a row.

[0009] Preferably, the side wall of the turntable is constructed with a limiting ring, and the inner wall of the pretreatment box is constructed with an annular groove to accommodate the limiting ring.

[0010] Preferably, the top of the base plate is provided with a threaded hole, and the bottom of the mounting post is screwed into the inside of the threaded hole.

[0011] Preferably, the top of the base plate has two rows of fixing holes arranged side by side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model drives the material barrel to rotate while simultaneously dispensing the treatment agent through the discharge pipe below the barrel. This allows the treatment agent to be evenly sprayed onto the aluminum chloride solution. By stirring the aluminum chloride solution while dispensing the treatment agent, the mixing reaction between the treatment agent and the aluminum chloride solution can be effectively accelerated, reducing the time required to remove organic matter.

[0014] 2. After the aluminum trichloride solution is discharged through the drain pipe, the blocking plate can be opened to maintain the interior of the pretreatment tank, making the maintenance of the pretreatment tank relatively convenient. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a pretreatment device for aluminum trichloride mother liquor, including a base plate 1 and a pretreatment tank 2 mounted on top of the base plate 1 by multiple sets of bolts. A mounting column 3 is mounted on one side of the top of the base plate 1, and a mounting plate 4 is bolted to the top of the mounting column 3. A motor 5 is connected to the bottom side of the mounting plate 4 via a motor mount, and the output end of the motor 5 is bolted to a turntable 6 located inside the pretreatment tank 2. The output end of the motor 5 can drive the turntable 6 to rotate. Two sets of material buckets 7 are symmetrically fixedly inserted into the top of the turntable 6. The rotation of the turntable 6 drives the material buckets 7 to rotate. A cover plate 8 is hinged to the top of the material buckets 7; opening the cover plate 8 allows the treated liquid to be discharged. Treatment agents such as hydrogen peroxide and activated carbon are added to the inside of the material tank 7, and the cover plate 8 is closed to form a seal. A discharge pipe 9 is fixedly inserted into the bottom of the material tank 7, and a control valve is installed on the discharge pipe 9. The treatment agent can be discharged through the discharge pipe 9 by opening the control valve. A rotating rod 11 is connected to the bottom center of the turntable 6 by screws. When the turntable 6 rotates, it can drive the rotating rod 11 to rotate. Multiple stirring rods 12 are evenly connected to the side wall of the rotating rod 11 by multiple sets of screws. The rotation of the multiple stirring rods 12 on the side wall of the rotating rod can make the aluminum trichloride solution and the treatment agent fully mixed. An inlet pipe is inserted into the upper part of one side wall of the pretreatment tank 2. The aluminum trichloride solution can be put into the pretreatment tank 2 through the inlet pipe.

[0022] Specifically, a drain pipe 15 is inserted into the bottom of one side wall of the pretreatment tank 2. The pretreated aluminum chloride solution can be discharged by opening the drain pipe 15. A flange is welded to the end of the drain pipe 15 away from the pretreatment tank 2 to facilitate the connection of the drain pipe 15 to external pipes.

[0023] Furthermore, a blocking plate 16 is hinged to the lower part of one side wall of the pretreatment box 2. The blocking plate 16 is flush with the corresponding side wall of the pretreatment box 2 to ensure the integrity and aesthetics of the device. The interior of the pretreatment box 2 can be maintained from this side by opening the blocking plate 16. A rubber layer 17 is bonded to the connection between the blocking plate 16 and the pretreatment box 2. The rubber layer 17 can increase the sealing performance to avoid leakage at the connection. A latch is installed between the blocking plate 16 and the corresponding side of the pretreatment box 2. The blocking plate 16 can be opened by opening the latch.

[0024] Furthermore, the stirring rod 12 has a rectangular structure, and multiple through holes 13 are arranged side by side on the side wall of the stirring rod 12. The arrangement of multiple through holes 13 can reduce the resistance encountered by the stirring rod 12 when stirring the aluminum trichloride solution, so that the stirring rod 12 can rotate smoothly.

[0025] It is worth noting that the side wall of the turntable 6 is constructed with a limiting ring 14, and the inner wall of the pretreatment box 2 is constructed with an annular groove to accommodate the limiting ring 14, ensuring that the turntable 6 can rotate smoothly and improving the sealing performance of the pretreatment box 2.

[0026] It is worth noting that the top of the base plate 1 has a threaded hole 18, and the bottom of the mounting post 3 is screwed into the inside of the threaded hole 18, which facilitates the disassembly and assembly of the mounting post 3 for maintenance.

[0027] It is worth mentioning that the top of the base plate 1 has two rows of fixing holes 10 arranged side by side. Screws can be installed in the two rows of fixing holes 10 to increase the stability of the base plate 1, and the overall stability of the device can also be improved.

[0028] Among them, motor 5 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: The aluminum trichloride solution is fed into the pretreatment tank 2 through the inlet pipe. Two sets of material tanks 7 contain hydrogen peroxide and activated carbon respectively. The motor 5 is started, which drives the turntable 6 to rotate, thereby driving the material tanks 7 and the rotating rod 11 to rotate. The feed pipe 9 below the material tank 7 feeds the material. Since the feed pipe 9 rotates with the material tank 7, the hydrogen peroxide can be sprayed more evenly above the aluminum trichloride solution. The multiple rotating stirring rods 12 can accelerate the mixing reaction of organic matter and hydrogen peroxide in the aluminum trichloride solution. The organic matter removed by the reaction is adsorbed by the activated carbon. After the reaction is completed, the drain pipe 15 is opened to discharge the pretreated aluminum trichloride solution.
