Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of stirrers, more particularly to a kind of spiral stirrer that strengthens raw material dispersion mixing. BACKGROUND

[0002] Semi-finished glue solution is a substance in the intermediate stage in the process of manufacturing final glue products (such as glue, adhesive tape, etc.). It is mainly composed of a suspended mixture of organic solvents, resins and inorganic fillers. The dispersion effect of inorganic fillers is directly affected by the stirring method and stirring time.

[0003] According to the patent with the patent authorization announcement number CN218307728U, a glue solution viscosity adjusting tank with uniform viscosity adjustment is disclosed, which comprises a viscosity adjusting tank body, a cover assembly, and a low-speed stirring unit. The top opening of the viscosity adjusting tank body is provided with a cover assembly, and the middle part of the cover assembly is provided with a low-speed stirring unit. The bottom of the viscosity adjusting tank body is semispherical, and the bottom end of the viscosity adjusting tank body is connected to a glue solution releasing assembly. Two pipe installation assemblies are arranged on the upper side of the fixed cover of the cover assembly, and a new glue inlet pipe and a viscosity adjusting solvent pipe are respectively fixedly connected to the two pipe installation assemblies. The bottom ends of the new glue inlet pipe and the viscosity adjusting solvent pipe extend to the top inside of the viscosity adjusting tank body, and the bottom ends of the new glue inlet pipe and the viscosity adjusting solvent pipe are fixed to the lower surface of the fixed cover of the cover assembly through a stable reinforcement assembly. A high-shear emulsifier is installed on the fixed cover of the cover assembly between the new glue inlet pipe and the viscosity adjusting solvent pipe. The bottom end of the high-shear emulsifier extends to the bottom inside of the viscosity adjusting tank body. The bottom of the new glue inlet pipe is connected to a new glue injection port, and the bottom of the viscosity adjusting solvent pipe is connected to a viscosity adjusting solvent injection port. The new glue injection port and the viscosity adjusting solvent injection port are both directed towards the high-shear emulsifier.

[0004] In the existing patent, the stirring blade in the low-speed stirring unit is a rectangular plate, and the contact area between the stirring blade and the inorganic fillers is limited. Secondly, the stirring rod is connected to the middle part of the cover, and the stirring blade can only contact the inorganic fillers in the middle of the tank body. This makes the stirring blade have poor dispersion and stirring effect on the raw materials in actual work, and long-time stirring is required, which affects the production efficiency. SUMMARY

[0005] In order to overcome the shortcomings of the existing patent, such as low dispersion and stirring effect of the stirring blade on the raw materials, long-time stirring required, and impact on production efficiency, the purpose of the utility model is to provide a spiral stirrer that strengthens raw material dispersion mixing.

[0006] The utility model discloses a technical scheme for a spiral agitator for intensifying raw material dispersion and mixing, which comprises an agitator tank, a top cover, a rotating motor, a rotating frame, a connecting shaft, a connecting plate, a driving motor, an agitator rod, a support plate, an inclined plate and spiral stirring blades.

[0007] Further, the utility model also comprises a viscometer, which is arranged at the lower right end of the agitator tank.

[0008] Further, the utility model also comprises a circular ring handle, which is symmetrically arranged at the top end of the top cover.

[0009] Further, the utility model also comprises a glue feeding pipe and a viscosity adjusting solvent pipe, which are arranged at the right and left sides of the top end of the top cover respectively.

[0010] Further, the utility model also comprises a ball valve, which is connected to the glue feeding pipe and the viscosity adjusting solvent pipe.

[0011] Further, the utility model also comprises a liquid discharge pipe, which is arranged at the bottom end of the agitator tank.

[0012] Further, the utility model also comprises a bolt, which is arranged in the same thread hole at the top end of the agitator tank and the top cover.

[0013] The utility model has the following advantages: 1. The driving motor drives the connecting shaft to rotate at a low speed, so that the agitator rod drives the spiral stirring blades to move in a circular motion around the inside of the agitator tank, thereby increasing the contact range of the spiral stirring blades and the liquid in the agitator tank. The rotating motor drives the agitator rod and the spiral stirring blades to rotate, so that the solution in the agitator tank is stirred uniformly, the stirring time of the solution is shortened, and the generation efficiency is improved.

[0014] 2. The viscometer is installed at the lower right end of the agitator tank, and the probe is inserted into the tank. The viscometer can monitor the viscosity change of the solution in real time and provide feedback information for people to close the rotating motor and the driving motor in time.
