Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of granular material cleaning devices. BACKGROUND

[0002] With the wide application of various inorganic, organic, polymer and its composite granular materials in chemical industry, medicine and other fields, various granular materials often attach impurities (such as dust, oil stains, residual solvent, unreacted monomer, etc.) due to synthesis reaction, additive residue or environmental contact in the production process, and need to improve purity through cleaning process to meet the requirements of subsequent processing or final use. However, the traditional cleaning technology and device have significant limitations in practical application, and technical innovation is urgently needed to solve the industry pain points.

[0003] The traditional cleaning technology usually adopts soaking or spraying cleaning method, which needs to rely on a large amount of water resources or chemical solvents, resulting in high energy consumption, high wastewater treatment cost and environmental pollution risk. Moreover, the traditional cleaning technology usually has poor cleaning effect, and when the materials are stacked, cleaning dead angles are easily formed, the cleaning liquid penetrates unevenly, and the cleaning is not thorough, which finally leads to more solvent residue. Solvent residue may affect material performance, especially for medical or food grade polymer particles, which may pose a safety hazard. In addition, the traditional cleaning method cannot meet the demand of cleaning multiple materials at the same time, and needs to be operated in batches, which will increase the cost of time and economy. Although the cleaning technology of ultrasonic cleaning can improve the uniformity of cleaning, the equipment is complex, the maintenance cost is high, and the high-frequency vibration may damage the microstructure of the polymer particles, resulting in the increase of the breakage rate of brittle materials. Mechanical cleaning usually adopts stirring or centrifugal separation technology, but it has poor adaptability to particles with large size difference, and it is easy to have cleaning dead angles or particle agglomeration, with low efficiency. Moreover, during stirring, the granular materials with microstructure are easily damaged.

[0004] Therefore, a granular material cleaning device is proposed to solve the above problems. UTILITY MODEL CONTENTS

The lower end of cleaning basket main body 1 is connected with bottom support 3 and is placed in cleaning pool 5, and the bottom of cleaning pool 5 is provided with rotor 6,

[0024] Specifically, the lower end surface of cleaning pool 5 is connected with drain pipe 7. The drain pipe 7 can be multiple. Cleaning liquid is injected into cleaning pool 5. For the material that needs to be cleaned multiple times, the cleaning liquid can be directly discharged through the drain pipe and then new cleaning liquid is added. The liquid level of the cleaning liquid is higher than the height of the material in the cleaning basket, so that the material to be cleaned and the cleaning liquid are in full contact.

[0025] Specifically, the cleaning basket main body 1 is composed of a screen 4. The cleaning liquid and the material to be cleaned can be fully mixed, and the material to be cleaned will not leak out. The upper part, the bottom and the surrounding of the basket body are tightly fixed by stainless steel rods to avoid material being stuck or leaking out at the gap. The screen aperture is selected to be 80% of the smallest particle size of the particles, so that the material particles will not leak out of the cleaning basket.

[0026] Specifically, the cleaning basket main body 1 is cylindrical, and the side edge is provided with a taking opening. The material is convenient to put in and take out.

[0027] Specifically, the cleaning basket main body 1 is made of 316L stainless steel. It is corrosion-resistant and has long service life.

[0028] Specifically, the distance between the lower end surface of the cleaning basket main body 1 and the rotor 6 is 5CM. The height is appropriate.

[0029] Specifically, the rotor 6 can be driven by magnetic force, and the rotation speed of the rotor can be set as required.

A cleaning pool 5 is sleeved outside the cleaning basket, the bottom of the cleaning pool 5 is provided with a drain pipe 7, and the entire cleaning device is composed. During the cleaning process, the cleaning material is added in the cleaning basket main body 1, the rotor 6 is placed at the bottom of the cleaning pool 5, the cleaning liquid is added in the cleaning pool 5 and the container is sealed. After starting the rotor, the cleaning liquid vortex penetrates the material layer, and the impurities are stripped and discharged through the screen.

[0031] Specifically, in the process of cleaning a single material, the polymer-inorganic particle to be cleaned is loaded into the cleaning basket, and the mesh size is selected to be 80% of the smallest particle size (for example, if the particle size is 1 mm, the mesh size is 0.8 mm). The rotor 6 is placed in the container, and the cleaning basket is placed in the cleaning pool 5, and anhydrous ethanol is added as the cleaning liquid. The ratio of the mass of the material to the volume of anhydrous ethanol is 1:25. If the amount of material is small, after adding anhydrous ethanol according to the ratio, the liquid level does not completely submerge the material, then anhydrous ethanol is injected until the liquid level is 2 cm higher than the material layer. Then seal the container, start the rotor 6 and set the rotation speed to 100 r / min, set the temperature to 25°C, and set the cleaning time to 1 hour. Through the rotation of the rotor, the anhydrous ethanol penetrates the material layer and deeply cleans the material layer. The impurities and residual solvents in the material are washed away to ensure the purity of the material. After cleaning is completed, the cleaning basket body 1 is removed, the cleaning liquid is discharged through the drain pipe 7, the material is separated from the cleaning liquid, and high-purity material is obtained.

During the cleaning process, different types of materials are wrapped with nylon filters 8 respectively, and after ensuring that the materials are wrapped in the nylon filters 8 without leakage, the materials wrapped with nylon filters are placed in the cleaning basket body 1 in order, and the materials should not be pressed against each other during the placement process to prevent the structure of the particles from being damaged after being pressed. The rotor 6 is placed at the bottom of the cleaning pool 5, and the cleaning liquid is added in the cleaning pool 5 and the container is sealed. After starting the rotor, the cleaning liquid vortex penetrates the material layer and strips off the impurities, which are then discharged through the screen.

The screen aperture is selected to be 80% of the smallest particle size (for example, the particle size is 1 mm, and the screen aperture is 0.8 mm). The rotor 6 is placed in the container, and the cleaning basket is placed in the cleaning pool 5, and anhydrous ethanol is added as a cleaning liquid in the cleaning pool 5. The addition ratio is material mass: anhydrous ethanol volume = 1:25. If the amount of the material is small, and the liquid level does not completely submerge the material after the anhydrous ethanol is added in proportion, the anhydrous ethanol is injected until the liquid level is 2 cm higher than the material layer. Then the container is sealed, the rotor is started, the rotating speed is set to 100 r / min, the temperature is set to 25℃, and the cleaning time is set to 1 hour. Through the rotation of the rotor, the anhydrous ethanol penetrates the material layer to clean the material layer in depth.

After the cleaning is completed, the cleaning basket body 1 is taken out, the cleaning liquid is discharged through the drain pipe 7, the materials in the nylon filter screens are separated from the cleaning liquid, and high-purity materials are obtained.

[0036] The particle material cleaning device, the screen and the rotor cooperate to make the cleaning liquid and the material fully contact through dynamic vortex flushing, and the single treatment capacity and the treatment effect are significantly improved. The screen structure of the cleaning basket body considers the sealing property and the permeability, and is suitable for composite particles of various sizes and particle size ranges. The large container can accurately control the cleaning parameters such as the cleaning temperature, the rotor speed and the cleaning time, and the separate nylon filter screen design can clean a plurality of materials at the same time to avoid cross contamination.
