Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a special mixer for polyaluminium chloride. Background Art

[0002] Polyaluminium chloride is an inorganic substance, an emerging water purification material, an inorganic polymer coagulant, referred to as polyaluminium. It has a high degree of electrical neutralization and bridging effect on colloids and particulate matter in water, and can strongly remove micro-toxic substances and heavy metal ions. It has stable properties. Due to the bridging effect of hydroxide ions and the polymerization of multivalent anions, the produced polyaluminium chloride is an inorganic polymer water treatment agent with a large relative molecular mass and a high charge.

[0003] Upon checking, the disclosure (announcement) number: CN218689440U discloses a polyaluminium chloride polymerization tank. This technology discloses "including a machine body, a feed port is provided on the top of the machine body, a discharge port is provided on the bottom of the machine body, a No. 1 motor is bolted to the top of the machine body, an output end of the No. 1 motor passes through the top of the machine body and is bolted to a stirring rod, the stirring rod is arranged inside the machine body, the inner wall of the machine body is rotatably connected to two threaded rods, the threaded rods pass through and are threadedly connected to a cleaning ring, and a cleaning brush is arranged on the outer arc wall of the cleaning ring". The cleaning ring moves up and down by reciprocating up and down, and then the cleaning brush moves in contact with the inner wall of the tank body for cleaning, so that the residue inside the tank body during processing can be quickly cleaned without manual cleaning operations, thereby reducing manual workload, improving cleaning efficiency, and ensuring the quality of subsequent processing.

[0004] A reciprocating cleaning brush is arranged in the polymerization tank to clean the material adhered to the inner wall of the tank, so as to reduce the difficulty of subsequent cleaning. However, the cleaning structure and the stirring structure are independent of each other, and the cleaning structure needs to be installed separately, which makes the overall structure complicated and the use cost increased. In addition, when performing the stirring operation, the material is stirred directly by the stirring rod without setting a structure for cooling the material. When the material is stirred for a long time, especially the polyaluminum chloride raw material has a high friction coefficient, it is easy to accumulate too much heat after a long time of friction, resulting in changes in the properties of the material and affecting the product quality. For this reason, we propose a special mixer for polyaluminum chloride to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1-Figure 6 As shown; a special mixer for polyaluminium chloride comprises a mounting base 1, a support platform 2 and a mixing tank 4, the top of the mounting base 1 is hinged with the support platform 2, and the top of the support platform 2 is fixedly mounted with the mixing tank 4.

[0029] In this embodiment: after checking the public (announcement) number: CN218689440U discloses a polyaluminium chloride polymerization tank, which discloses "including a machine body, a feed port is provided on the top of the machine body, a discharge port is provided on the bottom of the machine body, a No. 1 motor is bolted to the top of the machine body, the output end of the No. 1 motor passes through the top of the machine body and is bolted to a stirring rod, the stirring rod is arranged inside the machine body, the inner wall of the machine body is rotatably connected to two threaded rods, the threaded rods pass through and are threadedly connected to a cleaning ring, and the outer arc wall of the cleaning ring is provided with a cleaning brush". The cleaning ring moves up and down by reciprocating up and down, and then the cleaning brush moves in contact with the inner wall of the tank body for cleaning, so that the residue inside the tank body during processing can be quickly cleaned without manual cleaning operations, thereby reducing the workload of manual labor, improving the efficiency of cleaning, and ensuring the quality of subsequent processing.

[0030] A reciprocating cleaning brush is arranged in the polymerization tank to clean the materials adhered to the inner wall of the tank, so as to reduce the difficulty of subsequent cleaning. However, the cleaning structure and the stirring structure are independent of each other, and a cleaning structure needs to be installed separately, which makes the overall structure complicated and increases the cost of use. In addition, when performing the stirring operation, the material is stirred directly by a stirring rod without a structure for cooling the material. When the material is stirred for a long time, especially the polyaluminium chloride raw material has a high friction coefficient, it is easy to accumulate too much heat after a long period of friction, resulting in changes in the properties of the material and affecting the product quality. In view of this, in order to solve this technical problem, a water guide plate 7, an outer ring cooling tube 8, an inner ring cooling tube 9 and a rotating connector 11 are added to the application document.

At the same time, the water pump 16 supplies water, so that the cooling water circulates along the outer ring cooling tube 8 and the inner ring cooling tube 9. While the outer ring cooling tube 8 and the inner ring cooling tube 9 cool the material, they also have the function of cooling the material, thereby avoiding overheating and denaturation of the material after long-term stirring; at the same time, since the stirring blades 10 on the outer ring cooling tube 8 are tangent to the inner wall of the stirring tank 4, the material adhered to the inner wall of the stirring tank 4 can be cleaned by the stirring blades 10 when the outer ring cooling tube 8 rotates, thereby reducing the difficulty of subsequent cleaning.

When the outer ring cooling tubes 8 drive the stirring blades 10 to rotate, the inner wall of the stirring tank 4 can be cleaned synchronously, thereby reducing the difficulty of subsequent cleaning.
