[0002] Chemical powder mixing equipment is a key piece of equipment used in industries such as chemical, pharmaceutical, food, and building materials to uniformly mix various solid powders (or powders containing a small amount of liquid). Its core function is to break the agglomeration between material particles through mechanical action, achieve a uniform spatial distribution of different components, and ensure the stability of subsequent reactions, molding, or product quality.

[0003] Chinese Patent Application No. 202221577108.3 discloses a powder mixing device, including a tank and a stirring mechanism, and further including an adjusting rod, a wall scraper, a linkage rod and a lifting mechanism; the adjusting rod is coaxially arranged with the tank and is slidably connected to the tank; the wall scraper is rotatably connected to the adjusting rod and is capable of scraping the powder off the inner wall of the tank.

[0004] The powder mixing equipment in the aforementioned patent simply mixes the powder by stirring the materials with a stirring rod. This method of powder mixing is inefficient and results in uneven mixing of various materials, failing to achieve a fast and efficient powder mixing effect. Utility Model Content

[0005] The purpose of this invention is to provide a chemical powder mixing device that can accelerate the mixing efficiency of powders through internal circulation, thereby achieving a better powder mixing effect and solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chemical powder mixing device includes a mixing tank. A material cylinder is welded to the lower end of the mixing tank for mixing chemical powders. A feed hopper is welded to the lower end of the material cylinder, and an opening is provided on one side of the lower end of the material cylinder to facilitate the entry of powder.

[0008] An auger roller is installed inside the mixing tank. The upper end of the auger roller is equipped with a stirring paddle that extends to the upper end of the tank top cover and is connected to the drive assembly. The tank top cover is fixed to the top of the mixing tank. The drive assembly is fixed to the tank top cover.

[0009] The mixing tank has an inclined plate at the lower end of its interior. A negative pressure material pipe is connected to the outside of the mixing tank near the inclined plate. The negative pressure material pipe is connected to the inlet of the centrifugal feeder, and the outlet of the centrifugal feeder is connected to the mixing tank through the feeding pipe.

[0010] As a further technical solution of this utility model, a through hole is provided in the middle position of the inclined plate to facilitate the passage of the auger roller; then the bottom of the inclined plate is welded to the material cylinder.

[0011] As a further technical solution of this utility model, an inspection port is movably connected to one side of the upper end of the mixing tank; a cleaning chamber is movably connected to the outer side of the feed hopper connecting to the material cylinder.

[0012] As a further technical solution of this utility model, the negative pressure material pipe is provided with a discharge port on the bottom side of one end near the mixing tank; a butterfly valve is connected to the discharge port.

[0013] As a further technical solution of this utility model, the mixing tank is fixed on the support body; a controller is also fixed on one side of the support body; the controller is electrically connected to the drive assembly and the centrifugal feeder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, driven by the drive component, the auger roller conveys the powder upward through the material cylinder. When the powder reaches the top of the material cylinder, it falls to the sides, achieving the initial simple mixing of the powder. Then, the centrifugal feeder is turned on, and the powder is drawn into the negative pressure material pipe, and then conveyed to the mixing tank through the feeding pipe. The rotating stirring paddle disperses the falling powder. Through continuous internal circulation, the material can be quickly and evenly mixed, greatly improving the mixing efficiency of the powder.

[0016] 2. In this utility model, after the powder is mixed, the centrifugal feeder is turned off; the inclined plate setting gives the powder a self-flowing effect, allowing the powder to flow to the front end of the negative pressure feed pipe and discharge the mixed powder from the discharge port.

The material cylinder 2 is welded to a feed hopper 3 at its lower end, and an opening is provided on one side of the lower end of the material cylinder 2 to facilitate the entry of powder.

[0025] An auger roller 6 is installed inside the material cylinder 2. The upper end of the auger roller 6 is equipped with a stirring paddle, which extends to the upper end of the tank top cover 9 and is connected to the drive assembly 7. The tank top cover 9 is fixed to the top of the mixing tank 4. The drive assembly 7 is fixed to the tank top cover 9.

[0026] The lower end of the mixing tank 4 is inclined with an inclined plate 5. A negative pressure material pipe 10 is connected to the outside of the mixing tank 4 near the inclined plate 5. The negative pressure material pipe 10 is connected to the inlet of the centrifugal feeder 11, and the outlet of the centrifugal feeder 11 is connected to the mixing tank 4 through the feeding pipe 12.

[0027] By adopting the above technical solution, when mixing powders, firstly, one or more powders are proportioned according to a certain ratio, and then poured into the feed hopper 3. Under the drive of the drive component 7, the auger roller 6 conveys the powder upward through the material cylinder 2. When it is conveyed to the top of the material cylinder 2, the powder will fall to all sides, realizing the initial simple mixing of the powder. Then, the centrifugal feeder 11 is turned on, and the powder is drawn into the negative pressure material pipe 10, and then conveyed to the mixing tank 4 through the feeding pipe 12. The rotating stirring paddle disperses the falling powder. Through continuous internal circulation, the material can be quickly and evenly mixed, which greatly improves the mixing efficiency of the powder.

[0028] In this embodiment, the inclined plate 5 has a through hole in the middle position to facilitate the passage of the auger roller 6; the bottom of the inclined plate 5 is welded to the material cylinder 2. The negative pressure material pipe 10 has a discharge port 15 on the bottom side of one end near the mixing tank 4; a butterfly valve is connected to the discharge port 15.

[0029] The inclined plate 5 allows the powder to flow freely. When the centrifugal feeder 11 is not in operation, the powder can flow to the front end of the negative pressure feed pipe 10 and be discharged from the discharge port 15.

[0031] The inspection port 13 allows observation of whether internal components are damaged. Additionally, if there is bridging or poor powder flow inside, a cleaning rod can be inserted into the inspection port 13 to break up the bridging.

[0032] The cleaning chamber 16 is designed to clean the powder in the feed cylinder 2, preventing the accumulation of powder and thus preventing contamination of the equipment when mixing other powders.

[0033] In this embodiment, the mixing tank 4 is fixed on the support body 1; a controller 14 is also fixed on one side of the support body 1; the controller 14 is electrically connected to the drive assembly 7 and the centrifugal feeder 11.

[0034] The working principle of this utility model is as follows: When mixing powders, firstly, one or more powders are proportioned according to a certain ratio and then poured into the feed hopper 3. Under the drive of the drive component 7, the auger roller 6 conveys the powder upward through the material cylinder 2. When it reaches the top of the material cylinder 2, the powder will fall to the sides, achieving the initial simple mixing of the powder. Then, the centrifugal feeder 11 is turned on, and the powder is drawn into the negative pressure material pipe 10, and then conveyed to the mixing tank 4 through the feeding pipe 12. The rotating stirring paddle disperses the falling powder. Through continuous internal circulation, the material can be quickly and evenly mixed, greatly improving the mixing efficiency of the powder.
