Description

Technical Field

[0001] This utility model relates to a high-frequency vibration drying device, belonging to the technical field of drying equipment. Background Technology

[0002] In the electronics industry, the preparation of high-purity chemical solids often requires steps such as crystallization, washing, and drying to improve purity. These chemical solids typically include polymers and small molecules such as resins and photosensitizers. These substances are characterized by their fine powder composition; once they form a viscous slurry, solid-liquid separation becomes difficult. Traditional drying equipment often struggles to meet the requirements for cleanliness and residue control.

[0003] Currently, common drying equipment on the market, such as three-in-one, single-cone, and double-cone models, typically employs a stirring structure and uses a jacket for indirect heat transfer during the drying process. However, during vacuum negative pressure drying, the product often adheres to the stirrer and the inner wall of the equipment, making it difficult to remove.

[0004] Another common drying equipment is the drying oven. Although it is widely used in the production process, the product is statically dried, which can easily lead to clumping. It also requires a lot of manual operation, which increases the risk of contamination and exposure. Utility Model Content

[0005] The purpose of this invention is to provide a high-frequency vibration drying device to solve the above-mentioned problems.

[0006] The technical solution adopted by this utility model is: a high-frequency vibration drying device, including a drying host, an online gas heating device, a solvent recovery host, a vacuum pump, and an automatic control system;

[0007] The drying host includes a vessel for holding materials. The top of the vessel is provided with a feeding port and the bottom is provided with a discharging port. A thermometer is installed on the outer surface of the vessel and the probe extends into the interior of the vessel.

[0008] The bottom of the vessel body is also provided with a support, which is connected to a vibration motor, and the vibration motor is placed at the top center of the base;

[0009] The bracket is provided with a support foot on each of its four sides, and a shock-absorbing spring is installed at the bottom of each support foot. The bottom of the shock-absorbing spring is connected to the top of the base.

[0010] The gas online heating device and the solvent recovery host are both connected to the vessel body, and the vacuum pump is connected to the solvent recovery host;

[0011] The automatic control system is used to monitor and adjust parameters such as temperature, vibration frequency, and vacuum level to achieve precise control and management of the drying process.

[0012] It also includes a cleanroom, where the feed port and discharge port of the vessel are both located.

[0013] Furthermore, the gas online heating device includes a jacket for heating disposed on the outer surface of the vessel body, a gas source is connected to the jacket through a gas pipeline, and a gas heater is disposed on the gas pipeline.

[0014] Furthermore, the inner wall of the reactor is coated with a perfluoroalkoxy resin coating to prevent metallic impurities from falling into the material to be dried.

[0015] Optionally, the solvent recovery unit includes a solvent buffer tank and a condenser, so that the solvent generated during the process enters the solvent buffer tank through the discharge port for temporary storage, and is condensed and recovered by the condenser, thereby realizing the effective reuse of the solvent;

[0016] The solvent buffer tank is connected to the condenser, and the vacuum pump is connected to the condenser;

[0017] The solvent buffer tank and the condenser are connected by a branch pipe, the other end of which is connected to the interior of the reactor body.

[0018] Beneficial effects:

[0019] This drying equipment operates in a cleanroom, reducing environmental contamination of the dried materials;

[0020] High-frequency vibration is applied to the bottom of the vessel to cause the material to be dried inside the vessel to circulate along the wall and flow radially up and down, thereby achieving the drying and mixing of particles and preventing the dried material particles from sticking to the inner wall of the vessel.

[0021] Meanwhile, without the need for a complex stirring mechanism, high-frequency oscillation can ensure that there is no clumping during the drying process, and the output is clean with good drying effect. Attached Figure Description
