Description

Technical Field

[0001] The utility model relates to the technical field of water-based resin particle refinement, in particular to a low-temperature freezing and crushing water-based resin particle refinement device. Background Art

[0002] The refinement of water-based resin particles is an important process to improve the performance and application performance of water-based resins. The main purpose is to obtain a more uniform and delicate resin dispersion, thereby improving the gloss, adhesion, weather resistance and other properties of the final product. Low-temperature freezing crushing is a technology that uses low temperature to make the material brittle and then refines the particles through crushing.

[0003] Currently, when using low-temperature freezing and crushing technology, the material needs to be pre-cooled first, then cryogenically frozen, and then transferred to the crushing equipment for crushing. The above method requires multiple stages of operation, which is more troublesome and energy-intensive.

[0004] Therefore, in order to solve the above problems, a low-temperature freezing and crushing water-based resin particle refining device has been developed, which can realize integrated operation and pre-cool the material during the feeding process by the residual temperature during freezing. It is relatively convenient and energy-saving. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned method that requires multi-stage operation, is relatively troublesome, and has high energy consumption, the utility model provides a low-temperature freezing and crushing water-based resin particle refining device that can achieve integrated operation and pre-cool the material during the feeding process through the residual heat during freezing, which is relatively convenient and energy-saving.

[0006] The technical scheme is: a low-temperature freezing and crushing water-based resin particle refining device, including a bracket, a fluid mill bin, a discharge fan, a convex block, a discharge pipe, a cold air pipe, an inner pipe, a jet pipe, a jet nozzle, a precooling bin, a solenoid valve, a cover plate, a reflux pipe and a filter element. The upper part of the bracket is connected to the fluid mill bin, the bottom of the fluid mill bin is connected to the discharge fan, the inside of the fluid mill bin is connected to the convex block, the upper middle side of the fluid mill bin is connected to the discharge pipe, the left side of the fluid mill bin is connected to the cold air pipe, the cold air pipe is connected to the inner pipe, the upper side of the cold air pipe is connected to the jet pipe, the upper left part of the jet pipe is connected to the jet nozzle, the upper middle side of the jet pipe is connected to the precooling bin, the lower part of the precooling bin is connected to the solenoid valve, the top of the precooling bin is clamped with a cover plate, and the fluid mill bin and the precooling bin are connected. A reflux pipe is connected to which a filter element is connected, so that the material is located in the pre-cooling bin, which is closed by a cover plate, and the material in the pre-cooling bin is discharged by controlling the solenoid valve. During the discharge process, the material passes through the jet pipe at high speed into the inner pipe under the action of the jet nozzle, and is low-temperature frozen under the action of the cold air pipe. Then, the material continues to enter the fluid mill bin under the action of the high-speed jet and collides with the bump, thereby crushing the material. The material crushed to a specified size flows upward to the discharge pipe under the action of the discharge fan for discharge. The residual heat during freezing flows back to the pre-cooling bin through the reflux pipe to pre-cool the material, and the material is filtered through the filter element to avoid clogging the reflux pipe.

[0007] Optionally, a guide plate is also included. The left part of the fluid mill bin is connected with the guide plate, and the material is guided by the guide plate to be evenly dispersed in the fluid mill bin.

[0008] Optionally, the guide plate is an arc-shaped structure.

[0009] Optionally, a connecting flange is provided on the discharge pipe.

[0010] Optionally, a spoiler is also included. The inner tube is connected with the spoiler to disturb the material and improve its collision effect.

[0011] Optionally, the lower part of the pre-cooling bin is a conical structure, which is convenient for gathering and guiding the materials.

[0012] The utility model has the following advantages: the utility model allows the material to pass through the jet tube at high speed under the action of the jet nozzle, and freezes it at low temperature under the action of the cold air pipe. The frozen material enters the fluid grinding chamber for crushing, and the residual heat generated during freezing flows back to the pre-cooling chamber through the reflux pipe, which can realize integrated operation and pre-cool the material during the unloading process through the residual heat during freezing, which is more convenient and energy-saving.
