[0002] Polyaluminum chloride (PAC) is a new type of water purification material, an inorganic polymer coagulant, also known as polyaluminum chloride. PAC can be produced by chemically reacting calcium aluminate powder and hydrochloric acid in a high-temperature environment. The reaction requires a mixing device for thorough mixing.

[0003] Existing mixing devices for polyaluminum chloride, such as the polyaluminum chloride raw material mixing device disclosed in publication number CN213699499U, use a drive motor and gear transmission to rotate the horizontal and vertical stirring rods to stir the raw materials in different directions. However, during the addition of solid raw materials, a large amount of dust is easily generated due to the pouring and conveying friction of the materials. This dust not only pollutes the production environment and harms the health of operators, but long-term inhalation of dust may also cause occupational health problems such as respiratory diseases and pneumoconiosis. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing solid raw material mixing devices, which easily generate large amounts of dust during the addition of solid raw materials due to material dumping, conveying friction, etc. This dust not only pollutes the production environment and harms the health of operators, but long-term inhalation of dust may also cause occupational health problems such as respiratory diseases and pneumoconiosis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polyaluminum chloride raw material mixing device includes a mixing tank body. A drive motor is fixedly installed on the top of the mixing tank body.

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

[0020] Reference Figures 1-3 A polyaluminum chloride raw material mixing device includes a mixing tank body 1. The mixing tank body 1 is a prior art used in this field. Through the motor and gear structure inside the tank, the stirring rods in different directions are driven to rotate, thereby stirring the raw materials for producing polyaluminum chloride in different directions. The stirring direction is continuously changed while stirring, thereby improving the mixing effect. Details are omitted.

[0021] A drive motor 2 is fixedly installed on the top of the mixing tank body 1. The drive motor 2 is connected to a conveying box 3 through a material conveying structure. The material conveying structure includes a conveying cavity 9 opened inside the conveying box 3. A drive shaft 10 is rotatably connected inside the conveying cavity 9. A spiral blade 11 is fixedly installed on the outer wall of the drive shaft 10. One end of the drive shaft 10 passes through the outer wall of the conveying box 3 and is fixedly connected to the output end of the drive motor 2.

[0022] The cooperation between the spiral blade 11 and the drive shaft 10 in the material conveying structure makes the material conveying stable and reliable, greatly avoiding the problem of material blockage in the feeding hopper 4, and making the material conveying smoother.

[0023] The top of the conveying box 3 is connected to the feeding hopper 4. The outside of the feeding hopper 4 is provided with a dust suppression component 5 to reduce the dust generated during feeding. The dust suppression component 5 includes a left half ring 12 and a right half ring 13 sleeved on the outer wall of the feeding hopper 4. The outer walls of the left half ring 12 and the right half ring 13 are connected to the spray pipe 14. The spray pipe 14 is equipped with an atomizing nozzle. The outer walls of the left half ring 12 and the right half ring 13 are connected to the diversion pipe 15.

[0024] The nozzles 14 and atomizing nozzles on the left half-ring sleeve 12 and right half-ring sleeve 13 outside the feeding hopper 4 can continuously spray water mist during the feeding process, which can quickly absorb and settle the dust generated by the material pouring and conveying friction, effectively reducing the dust content in the production environment. The left half-ring sleeve 12 and right half-ring sleeve 13 are connected by a hinge, and both are hollow, so that water can be transported to the nozzle 14 through the left half-ring sleeve 12 and right half-ring sleeve 13.

[0025] The left outer wall of the mixing tank body 1 is provided with a water supply component 6 for providing water flow to the dust suppression component 5. The water supply component 6 includes a water supply pipe 16, a water tank 17 and a water pump 18. The water tank 17 is fixedly installed on the left outer wall of the mixing tank body 1, the water pump 18 is fixedly installed in the water tank 17, and the water supply pipe 16 is fixedly installed on the drain pipe of the water pump 18.

[0026] The shunt pipe 15 is made of silicone flexible tubing to facilitate the installation of the left half-ring 12 and the right half-ring 13. Rigid tubing would not allow the left half-ring 12 and the right half-ring 13 to open and close smoothly.

[0027] A transparent observation window 7 is fixedly installed on the front of the mixing tank body 1 to facilitate observation of the mixing effect.

[0028] The connection between the transparent observation window 7 and the mixing tank body 1 is equipped with high-temperature resistant waterproof adhesive to prevent leakage during mixing. The transparent observation window 7 provides operators with a direct window to observe the mixing effect, making it easy to monitor the state and degree of mixing of materials in real time, promptly detect and deal with possible problems such as uneven mixing and material accumulation, and improve the controllability and efficiency of the production process.

[0029] The mixing tank body 1 has a circular mixing chamber 8 inside, and the edge of the circular mixing chamber 8 is set in a semi-circular shape.

[0030] The circular mixing chamber 8 inside the mixing tank body 1 has a semi-circular edge. This unique structural design allows the material to flow and tumble more smoothly during the mixing process, eliminating dead corners and making discharge smoother.

[0031] The water supply pipe 16 is fixedly connected to the diversion pipe 15 via a tee. The diversion pipe 15 is made of silicone. The outer walls of the left half-ring 12 and the right half-ring 13 are both fixedly connected to the connecting blocks 19, and bolts and nuts 20 are inserted into the connecting blocks 19.

[0032] The left half-ring 12 and the right half-ring 13 in the dust suppression component 5 are connected by bolts and nuts 20, which facilitates disassembly, installation and maintenance.

[0033] It should be noted that the specific models and specifications of the drive motor 2 and water pump 18 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here. Both can be powered by external devices and controlled to turn on and off.

[0034] Working principle:

[0035] First, the operator feeds the raw materials for producing polyaluminum chloride into the conveying box 3 through the feeding hopper 4. After the drive motor 2 starts, it drives the transmission shaft 10 and the spiral blades 11 to rotate, and stably conveys the raw materials into the circular mixing chamber 8 of the mixing tank body 1. During this process, the left half ring 12 and the right half ring 13 of the dust suppression component 5 continuously spray water mist through the atomizing nozzles to effectively adsorb the dust generated during feeding and conveying. The water pump 18 in the water tank 17 supplies water to the spray pipe 14 through the water supply pipe 16 and the silicone diverter pipe 15 to ensure the dust suppression effect. At the same time, the transparent observation window 7 facilitates real-time monitoring of the material status.

[0036] Subsequently, the motor inside the mixing tank 1 drives the multi-directional stirring rod to alternately stir the raw materials. The semi-circular edge of the mixing chamber 8 design allows the materials to tumble and mix without dead corners. After mixing, the materials are discharged from the bottom. Operators can loosen the bolts and nuts 20 to disassemble the left half ring 12 and the right half ring 13 for cleaning and maintenance. The whole process realizes efficient material transportation, mixing and dust control, improving the safety of the production environment and mixing efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
