Description

Technical Field

[0001] The invention relates to a high-speed mixer for surface treatment of solid materials, belonging to the field of special equipment for preparing polymer modified materials. Background Art

[0002] High-speed mixers are widely used in polymer material processing, biology, medicine, mining and other industries. They have the characteristics of high mixing efficiency, easy operation and maintenance, and are mainly used for mixing solid and solid-liquid materials. When mixing solid-liquid materials, usually a certain amount of solid is added to the high-speed mixer from the feed port, and then a certain amount of liquid is added at once or in batches to mix the materials.

[0003] Although the existing high-speed mixer equipment and technology are simple and reliable, they also have obvious shortcomings and technical defects, especially when adding liquid surface treatment agent during solid-liquid mixing. If the liquid surface treatment agent is directly poured into the mixing pot of the high-speed mixer before mixing, or the liquid surface treatment agent is added dropwise during the stirring process, the liquid surface treatment agent using the above-mentioned feeding method is prone to local focusing and uneven dispersion, and a longer mixing time is required to obtain the expected mixing effect; especially when a small amount of liquid surface treatment agent is used to coat the solid material, a longer mixing time is required to achieve uniform mixing. Too long mixing time not only affects the mixing efficiency, but also causes overheating and decomposition of materials with poor heat resistance.

[0004] In addition, in the solid-liquid mixing feeding method of atomizing the liquid surface treatment agent and then spraying it into the mixing pot during the mixing process, although the liquid can be formed into smaller droplets, even below the micron level, the stirring effect during the mixing process will cause the flow direction and flow rate of the materials in the mixing pot to change, resulting in air flow fluctuations in the mixing pot. The atomized droplets will be affected by the air flow fluctuations and reduce the mixing effect. Some droplets with too small diameters will adhere to the top cover of the mixing pot, or diffuse into the environment with air flow fluctuations in the case of poor sealing, causing pollution, and also causing waste of the liquid surface treatment agent. In addition, when the amount of liquid surfactant added is large, the atomization addition requires a long atomization time, which will lead to a long cycle of the entire mixing process, reducing the mixing efficiency and economic benefits. Summary of the invention

[0005] The present invention provides a high-speed mixer for surface treatment of solid materials, which can effectively improve the mixing effect of solid-liquid mixing. The specific technical scheme is as follows:

[0006] A high-speed mixer for surface treatment of solid materials, characterized in that it includes a base and a motor, a mixing pot, a liquid storage tank and a spray pump arranged on the base, a stirrer is arranged at the bottom of the mixing pot, and the stirrer is connected to the motor through a belt; a guide plate is arranged on the inner side of the mixing pot, a diverter plate is arranged in front of the confluence area of ​​the guide plate, and the diverter plate is connected to the fixing device of the upper cover through a connecting rod; a tail nozzle is arranged at the tail of the outer arc surface of the diverter plate, near the confluence area of ​​the guide plate, and the tail nozzle is connected to the liquid storage tank containing a liquid surface treatment agent through a conduit.

[0007] The liquid storage tank containing the liquid surface treatment agent is connected to the spray pump, and the liquid surface treatment agent is pumped by the spray pump through a conduit to the tail nozzle of the diverter plate in the mixing pot. The material in the mixing pot forms a rotating flow under the high-speed rotation of the agitator, and the rotating flow forms an inner flow and an outer flow after passing through the front end of the diverter plate; the tail nozzle at the end of the diverter plate sprays the liquid surface treatment agent onto the surface of the solid particles of the inner flow and the outer flow, and an interlayer spraying area between the inner flow and the outer flow is formed at the tail of the diverter plate, so that the inner flow and the outer flow passing through the interlayer spraying area form an inner mixed flow and an outer mixed flow.

[0008] The confluence area of ​​the guide plate is an inner arc-shaped surface, and the confluence area of ​​the inner arc-shaped surface can make the inner mixed material flow with liquid surface treatment agent and the outer mixed material flow passing through the interlayer spraying area merge with each other to form a converged material flow; during the confluence process of the inner mixed material flow and the outer mixed material flow on the guide plate, the solids and liquids between different material flows produce friction, slip and diffusion with each other; the converged material flow formed by the confluence area of ​​the guide plate is introduced into the central area of ​​the mixing pot, and after being mixed and stirred by the agitator, it forms a rotating material flow again for mixing.

[0009] The cross-section of the diverter plate is crescent-shaped, and has an inner arc surface and an outer arc surface of the diverter plate; a catheter joint is provided on the top of the diverter plate, one end of the catheter joint is connected to the catheter, and the other end is connected to the nozzle flow channel on the diverter plate, the end of the nozzle flow channel is connected to the tail nozzle, and a nozzle groove is provided on the tail surface of the outer arc surface of the diverter plate, and the tail nozzle is located in the nozzle groove.

[0011] A discharge port is arranged on one side of the bottom of the mixing pot.

[0012] The upper cover is provided with a through hole through which the conduit can pass, and a dustproof rubber ring is provided between the through hole and the conduit to prevent impurities from entering the mixing pot; one end of the conduit is connected to the spray pump, and the other end is connected to the conduit connector on the diverter plate.

[0013] The agitator comprises a rotating shaft, an upper impeller and a lower impeller, wherein the upper impeller and the lower impeller are fixed on the rotating shaft, and a driven wheel is also arranged on the rotating shaft, and the driven wheel is connected to the motor through a belt, and the motor drives the belt to run, thereby driving the rotating shaft to rotate to achieve mixing of materials.

[0014] The output shaft of the motor is fixedly connected with a connecting shaft, and a driving wheel is arranged on the connecting shaft. The driving wheel is connected with the driven wheel via a belt. The motor provides power to drive the belt to run and then drive the agitator to rotate.

[0015] The length of the lower impeller is longer than that of the upper impeller, which can accelerate the mixing of materials in the mixing pot and make the mixing more uniform.

[0016] The beneficial effects of the present invention are as follows: 1. Through the combined structural design of the diverter plate and the guide plate, the solid material and the liquid surface treatment agent are mixed well, the mixing cycle is short, the cost is low, and the economic benefits are high. 2. The solid material and the liquid surface treatment agent are mixed evenly, the coating effect is good, and the utilization efficiency of the surface treatment agent can be effectively improved. 3. The interlayer spraying area formed by the diverter plate and the tail nozzle can effectively reduce the interference of the tiny droplets with the air flow fluctuation, reduce the loss of the liquid surface treatment agent, reduce environmental pollution, and have high economic benefits.
