DETAILED DESCRIPTION

Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

Embodiment: Please refer to Figures 1-8. The bottom mounting plate 1 is equipped with an adjustable feeding multi-station magnetic grinding structure A, a pressurized spraying rotary powder spraying grinding structure B, and a replaceable pressurized cleaning structure C.

When using the adjustable feeding multi-station magnetic grinding structure, the equipment base A1 is used to support the upper equipment. When preparing for grinding, open the sealing thread A22 installed on the powder replenishing port A4, and put the ground abrasive walnut shell powder into the storage barrel A2 through the powder replenishing port A4. After the replenishment is completed, tighten the sealing thread A22 to ensure the sealing of the storage barrel A2, operate the controller matched with the equipment to start the equipment, and the first electromagnetic coil A5 installed above the inside of the powder storage chamber A3 is energized and started to generate a magnetic field under the control of the control system. The first electromagnetic coil A5 attracts the movable body installed on the lifting frame A7 below through the magnetic field. The movable lower magnet A8 moves upward at a uniform speed, and the movable lower magnet A8 moves upward at a uniform speed and slowly on the sliding frame A6 through the lifting frame A7, so that the abrasive walnut shell powder enters the first powder discharge hopper A13 and the second powder discharge hopper A15. The abrasive in the second powder discharge hopper A15 is transported to the feed pipe A12 through the auxiliary powder discharge pipe A14 to realize the collection of the abrasive. The abrasive is transported to the feed pipe A12 fixed on the door-shaped bracket A11 through the first powder discharge hopper A13 and the second powder discharge hopper A15. When feeding, the two conical powder discharge hoppers cooperate to discharge the material mainly to prevent the abrasive from being blocked due to pressure when entering the hopper mouth. The powder discharge pressure can be shared by cooperating with the double powder discharge hoppers to prevent abrasive clogging. At the same time, the clogging pressure sensor A24 installed on the second powder discharge hopper A15 monitors the pressure at the hopper mouth in real time. When it is found that the pressure is too high and a blockage may occur, the compressed air pump A16 installed on the side wall of the storage barrel A2 starts to compress the air and increase the gas pressure to produce high-pressure gas. The high-pressure gas is ejected through the anti-blocking air inlet pipe A17, and the high-pressure gas is injected to the position of the second powder discharge hopper A15, which effectively prevents abrasive clogging. When the abrasive inside the storage barrel A2 is used up and needs to be replenished, the controller sends a control signal to change the first electromagnet coil A5. The direction of the current makes the first electromagnet coil A5 generate a magnetic field that repels the moving lower magnet A8, thereby controlling the moving lower magnet A8 to move downward to the bottom of the powder storage chamber A3, and realizing the resetting of the moving lower magnet A8. When variable speed feeding is required, the air pressure pump A9 can cooperate with the air delivery pipe A10 to output high-speed airflow, and the electromagnetic valve A23 embedded on the lower wall of the powder storage chamber A3 is opened to allow the high-speed airflow to enter the powder storage chamber A3. The abrasive is driven to enter the first powder discharge hopper A13 and the second powder discharge hopper A15 by the way of lifting the abrasive driven by the airflow. The speed of powder feeding is adjusted by adjusting the airflow velocity to realize variable speed discharging.

After entering the feed pipe A12, the abrasive is transported to the right, and the lower pipe mouth of the metal capillary is placed in the cavity in the middle of the fixed shell A25 installed on the upper wall of the grinding fixed table A20, so that the tube wall of the metal capillary is in the middle position of the fixed shell A25 and the fixed spring piece A28 installed on the grinding fixed table A20 through the rod bracket. The controller sends a control signal to control the second electromagnet coil A27 installed in the installation cavity A26 to be energized and started to generate a magnetic field. The magnetic field generated by the second electromagnet coil A27 attracts the fixed spring piece A28 in the metal capillary, and the strip metal sheets on both sides of the fixed spring piece A28 are deformed by the magnetic attraction and press against the inner wall of the metal capillary, thereby cooperating with the second electromagnet coil A27 to fix the metal capillary. The switch valve A18 is opened, and the abrasive is transported downward through a pair of feed pipes A19 to grind The material enters the metal capillary. When the abrasive falls to the bottom of the metal capillary due to gravity, it is blocked due to the fixed spring piece A28. The controller sends an electrical signal to control the current of the second electromagnet coil A27 to adjust the magnetic field strength. The fixed support force on the metal capillary is changed by changing the magnetic force of the second electromagnet coil A27, so that the metal capillary moves downward and gradually penetrates the through hole opened on the grinding fixed table A20. When the metal capillary moves back and forth up and down, the fixed spring piece A28 drives the abrasive to move in the metal capillary to grind and polish the inner wall, thereby achieving the purpose of feeding and grinding and polishing through magnetic force. After the grinding and polishing is completed, the metal capillary is taken away, and the abrasive will fall into the recovery box A21 installed under the grinding fixed table A20 to realize the recycling of the abrasive.

The equipment bracket B1 is equipped with a pressurized jet rotary powder spraying grinding structure. When in use, open the tightening thread B19 installed on the powder inlet B4 to ensure sealing, and put the abrasive walnut shell powder used for grinding into the powder chamber B3 opened inside the powder storage box B2 through the powder inlet B4 to ensure that there is enough abrasive in the powder chamber B3. Open the observation window B22, and put several metal capillaries that are bound and fixed into the middle position of the inner rotating sleeve B26. The several metal capillaries are interference fixed by the deformation of the rubber support ring B27 arranged on the inner wall of the inner rotating sleeve B26. When fixing, align the pipe mouths of the metal capillaries with the powder outlet of the spiral powder spraying head B17 one by one, and control the matching with the equipment. The controller starts the equipment. The controller sends out a start electrical signal to control the air compression pump B5 installed on the powder storage box B2 to start. The air compression pump B5 starts to compress the air pressure through the piston in the pump body, thereby increasing the air pressure. The compressed air is transported to the pressurized pipe B8 installed in the powder chamber B3 through the support frame B7 through a pair of air inlet connecting pipes B6. The compressed air in the pressurized pipe B8 is ejected from the air outlet on the pressurized jet pipe B9 installed below, blowing the abrasive in the powder chamber B3 to the right, and blowing the walnut skin powder abrasive into the powder inlet hopper B15. Since the pressurized jet pipe B9 continues to blow for a long time, the walnut skin powder particles are small and are subjected to wind pressure for a long time, and may become compacted. The stirring frame B12 mounted on the rotating shaft B11 is driven by the driving motor installed above the powder storage box B2, and cooperates with the first rotating bearing B20 on the shaft fixing block B10 to rotate slowly. The abrasive is stirred by the rotation of the stirring frame B12 to prevent the abrasive from being compacted. The abrasive enters the powder inlet hopper B15 along with the high-pressure airflow, and is transported through the conveying pipe B14. A number of spiral powder outlets are provided on the spiral powder spraying head B17 installed on the rotating connecting pipe head B16. Under the action of the high-pressure airflow, the spiral powder spraying head B17 cooperates with the rotating connecting pipe head B16 to perform rotating powder spraying. Due to the spiral powder spraying outlet cooperating with the rotation of the spiral powder spraying head B17 The spiral powder spraying head B17 rotates to make the sprayed abrasive in a spiral shape. When the spiral powder spraying head B17 rotates, the inner rotating sleeve B26 is driven to rotate through the connecting rod B21. The inner rotating sleeve B26 rotates on the outer supporting sleeve B24 installed in the grinding box B13 through the fixing rod B23 through the second rotating bearing B25. A pair of inner rotating sleeves B26 rotate synchronously with the spiral powder spraying head B17, so that the spiral powder spraying head B17 sprays the abrasive in a spiral shape into the metal capillary. The abrasive sprayed in a spiral shape can effectively increase the friction between the abrasive and the inner wall of the metal capillary to ensure the grinding effect. The abrasive after grinding falls into the waste box B18 installed below, thereby realizing the rotary powder spraying grinding of the metal capillary;

When using the replaceable pressurized cleaning structure, the fixed base C1 supports the entire device above, the observation box door C19 is opened, and the bound and fixed metal capillary is placed on the cleaning fixed grid C8 above the electric rotating seat C7 installed in the cleaning chamber C4 through the mounting bracket C6 for installation and fixing. After the fixing is completed, the observation box door C19 is closed to ensure the sealing during cleaning, and the controller matching the equipment is operated to start the equipment. The external controller sends a control signal to start the equipment. The delivery pump C11 installed on the mounting plate C10 through the fixing bolts C20 starts after receiving the control signal. The rotating impeller inside the delivery pump C11 starts to rotate at high speed, and the centrifugal force and the pressure difference on both sides cooperate with the suction pipe C12 to pump the water tank C The water in the cleaning tank C2 is pumped out upwards, and the water is continuously injected into the activated carbon filter box C14 installed on the side wall of the cleaning tank C2 through the supporting seat C21 through the connecting pipe C13. Since the activated carbon has a large number of micropores and mesopores, these micropores and mesopores provide a huge surface area, thereby increasing the ability of the activated carbon to adsorb pollutants. The pumped water is filtered and purified by adsorption and filtration. The purified water is transported to the water inlet position on the upper wall of the cleaning tank C2 through the water delivery pipe C15 to achieve the purpose of purifying water supply. While the water is injected, the booster pump C16 installed on the right side of the cleaning tank C2 is started. The booster pump C16 compresses the gas to increase the gas pressure. The high-pressure gas is transported to the water delivery pipe C17 connected to the water delivery pipe C2. 15 connection position, so as to adjust the pressure of the cleaning spray. When cleaning is carried out, the switch control valve C18 is opened, and the filtered and pressurized water is sprayed downward. The cleaning water is transported downward from the outlet opened on the water outlet connection block C23 connected to the switch control valve C18 and sprayed out through the micro outlet C26 installed on the lower wall surface. It is sprayed out through the fine water channel opened on the micro outlet C26. The smaller diameter pipeline can increase the water flow speed, thereby increasing the water pressure. The high-pressure sprayed water flow is used to rinse and clean the stubborn impurities left on the surface of the metal capillary due to grinding and polishing. When the preliminary cleaning is completed, the hydraulic push rod C28 installed in the cleaning box C2 through the fixing frame C27 starts the extension and retraction of the output end, and drives the hydraulic push rod C28 through the connecting block C29. The water outlet connection block C23 cooperates with the sliding sleeve C24 to move on the sliding rod frame C22, so that the micro water outlet C26 is replaced by the main water outlet C25 and connected to the switch control valve C18 for flushing and cleaning with normal water pressure. While flushing and cleaning, the electric rotating seat C7 rotates synchronously, and the rotation of the electric rotating seat C7 drives the metal capillary to rotate, thereby increasing the contact area with the water flow to ensure the cleaning effect. The waste water generated after cleaning leaks into the wastewater chamber C5 through the drainage grid C3 installed in the middle of the cleaning box C2, and the waste water is discharged through the drainage pipe set on the rear wall of the wastewater chamber C5, thereby achieving adjustable and replacement flushing and cleaning of the metal capillary to ensure the cleanliness of the metal capillary.
