Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a device for stirring resin and metal powder. Background Art

[0002] In modern chemical industry, material science and manufacturing, the mixing technology of resin and metal powder is widely used in the manufacture of high-performance composite materials, coatings, adhesives, functional plastics and other products. At present, the mixing of resin and metal powder is to directly add the two into a stirring device for stirring and mixing. If the temperature in the stirring device is too high, the metal powder absorbs heat and its fluidity decreases, which will cause the material to settle at the bottom of the stirring device. If the temperature in the stirring device is too low, the material will stick in the stirring device, and the uniformity and stability of the prepared mixture cannot be guaranteed.

[0003] In order to effectively avoid the temperature inside the stirring device from being too high or too low, and to ensure the uniformity and stability of the prepared mixture, the Chinese utility model patent with the publication number of "CN217093152U" discloses a metal powder coating mixing and stirring device, which includes a mixing tank, a feeding port and a driving motor are provided at the top of the mixing tank, a discharge port is provided at the bottom, a spiral stirring rod is provided in the mixing tank, the spiral stirring rod is a hollow structure, the top of the mixing tank is penetrated, and a rotating joint is provided, and a bearing seat and a driven gear are provided on the outside, the rotating joint is externally connected to a branch liquid inlet pipe, and a heat source and a cold source are connected on the branch, a driving gear is provided on the output shaft of the driving motor, and the driving gear is meshed and driven with the driven gear. The bottom of the spiral stirring rod penetrates the mixing tank and is a liquid outlet, and a plurality of stirring rods are provided below the spiral stirring rod, and a plurality of stirring sticks are provided below the stirring rod. By providing a spiral stirring rod with a hollow structure, and then inputting a heat source or a cold source according to the situation, the temperature in the tank body is adjusted, which can effectively avoid the internal temperature being too high or too low to cause deposition or adhesion, and improve the use performance and practicality. However, the spiral stirring rod in this device can only stir the material in the upper part of the mixing tank, and the stirring rod and stirring stick can only stir the material at the bottom of the mixing tank. Since the slurry is deposited at the bottom of the mixing tank, the resin and metal powder are not mixed evenly, resulting in unstable properties of the final mixture. Utility Model Content

[0004] The utility model aims to provide a device for stirring resin and metal powder, so as to solve the problem that the existing device causes uneven mixing of resin and metal powder, resulting in unstable properties of the finally formed mixture.

[0005] In order to solve the above problems, the technical solutions provided are as follows:

[0006] A resin and metal powder stirring device comprises a mixing tank, wherein a stirring shaft is arranged in the mixing tank, a plurality of first stirring blades are arranged on the upper part of the stirring shaft, the blade ends of the first stirring blades are bent and folded downward, a plurality of second stirring blades are arranged on the lower part of the stirring shaft, the blade ends of the second stirring blades are bent and folded upward, and the top end of the stirring shaft extends out of the mixing tank and is fixedly connected to a motor.

[0007] The basic principle of the above technical solution is that: the raw materials enter the mixing tank, the motor is turned on to drive the stirring shaft to rotate, the raw materials are stirred and dispersed by the first stirring blade and the second stirring blade, and the slurry flows to the bottom from all sides. Since the top of the second stirring blade is in the opposite direction to the top of the first stirring blade, the mixture reaching the bottom returns to the top again, and the cycle is repeated, finally achieving uniform mixing of the resin and the metal powder raw materials, so that the properties of the final mixture are stable.

[0008] The beneficial effect of the above technical scheme is that compared with the existing spiral stirring rod, stirring rod and stirring stick which can only stir the materials in the mixing tank separately up and down, the first stirring blade and the second stirring blade with opposite directions at the top of the present scheme can continuously stir the materials in the upper and lower parts of the mixing tank, so that the resin and the metal powder raw materials are evenly mixed to form a mixture with stable properties.

[0009] Furthermore, a scraper bar in contact with the inner wall of the mixing tank is fixedly connected to the end of the second stirring blade. The scraper bar scrapes along the inner wall of the mixing tank as the second stirring blade rotates, and the material attached to the inner wall of the mixing tank is continuously scraped off for mixing and stirring, so as to avoid the material being attached to the inner wall of the mixing tank and thus not being stirred, resulting in uneven mixing and stirring.

[0010] Furthermore, the mixing tank is composed of an inner shell and an outer shell, a cavity is formed between the inner shell and the outer shell, a liquid inlet is provided on one side of the top of the cavity, a branch liquid inlet pipe is connected to the liquid inlet, and the branch is connected to the heat source and the cold source, a liquid outlet is provided on the other side, a coil is provided in the cavity, the two ends of the coil are respectively connected to the liquid inlet and the liquid outlet, and a mixed liquid of the heat source and the cold source flows in the coil. The mixed liquid of the heat source and the cold source is placed in the cavity, and the mixed liquid fully contacts the outer wall of the inner shell, so that the temperature of all spaces in the inner shell is kept consistent, and there will be no temperature difference problem.

[0011] Furthermore, the inner wall of the shell is provided with a heat insulation layer, which can prevent a large amount of heat from being lost in the cavity, thus causing energy waste.

[0012] Furthermore, the top of the mixing tank is provided with a feed inlet, and the bottom of the mixing tank is provided with a discharge port. The resin and metal powder before mixing enter the mixing tank through the feed inlet, and the mixed mixture flows out of the mixing tank through the discharge port.

[0013] Furthermore, a temperature sensor is provided inside the mixing tank, a controller is provided outside the mixing tank, solenoid valves are provided on the branches of the branch liquid inlet pipe, and the temperature sensor, the motor and the solenoid valve are all electrically connected to the controller. The controller controls the temperature sensor, the solenoid valve and the motor in a linkage manner to realize intelligent and automatic control of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The embodiment is basically as shown in the attached Figure 1 As shown:

[0018] A device for mixing resin and metal powder, such as Figure 1 As shown, it includes a mixing tank 1, in which a stirring shaft 2 is provided, and a plurality of first stirring blades 3 with blade ends folded and bent downward are provided on the upper part of the stirring shaft 2, and the first stirring blades 3 with blade ends folded and bent downward generate a downward rotary force to push the material in the mixing tank 1 downward, and a plurality of second stirring blades 4 with blade ends folded and bent upward are provided on the lower part of the stirring shaft 2, and the second stirring blades 4 with blade ends folded and bent upward generate an upward rotary force to stir the material in the mixing tank 1 upward, so that the mixture at the bottom of the mixing tank 1 returns to the upper part of the mixing tank 1 again, and the end of the second stirring blade 4 is fixedly connected to a laterally arranged connecting rod 5, and the end of the connecting rod 5 is fixedly connected to a scraper 6 arranged vertically and in contact with the inner wall of the mixing tank 1, and the scraper 6 scrapes along the inner wall of the mixing tank 1 as the second stirring blade 4 rotates, and the material attached to the inner wall of the mixing tank 1 is continuously scraped off for mixing and stirring, and the top end of the stirring shaft 2 extends out of the mixing tank 1 and is fixedly connected to the output shaft of the motor 7.

[0019] The mixing tank 1 is composed of an inner shell 1-1 and an outer shell 1-2, and a cavity 1-3 is formed between the inner shell 1-1 and the outer shell 1-2. A liquid inlet 1-4 is provided on one side of the top of the cavity 1-3. The liquid inlet 1-4 is connected to a branch liquid inlet pipe 8, and the branch is connected to a heat source 15 and a cold source 16. Electromagnetic valves 14 are provided on the branches of the branch liquid inlet pipe 8, and a liquid outlet 1-5 is provided on the other side. A coil 1-6 is provided in the cavity 1-3, and both ends of the coil 1-6 are respectively connected to the liquid inlet 1-4 and the liquid outlet 1-5. A mixed liquid of the heat source 15 and the cold source 16 flows in the coil 1-6, and an insulating layer 9 is provided on the inner wall of the outer shell 1-2.
