Description

Technical Field

[0001] The invention relates to the field of screening technology, and in particular to a screening and classification device for preparing traditional Chinese medicine. Background Art

[0002] Chinese medicine processing is a traditional craft that aims to perform necessary processing on Chinese medicinal materials through various methods to enhance the efficacy of the medicine, reduce toxicity or side effects, and facilitate storage and use. Stir-frying is one of the methods of Chinese medicine processing.

[0003] Chinese patent CN216261851U discloses a Chinese medicine preparation and screening device, which includes a box, a medicine inlet at the top of the box, and a collection box placed under the box for receiving residues. Among them, a first sieve plate and a second sieve plate are arranged in sequence from top to bottom in the box. The first sieve plate and the second sieve plate are both arranged at an angle. The first sealing plate and the second sealing plate are respectively arranged at the output ends of the first sieve plate and the second sieve plate, and the first sealing plate and the second sealing plate are both disassembled and assembled on one side of the box. A first collecting bin and a second collecting bin are respectively arranged below the first sealing plate and the second sealing plate. A power assembly is arranged in the box, and the power assembly constitutes the reciprocating sliding of the first sieve plate and the second sieve plate in the height direction or the horizontal direction.

[0004] During the preparation of Chinese medicine, the frying method is used, and other auxiliary materials are added during the processing. For example, bran frying is to add bran (wheat husk) during frying and fry it together with the medicinal materials. The effect of wheat husk can reduce the dryness or toxicity of the medicinal materials. However, in the frying process, the thickness of the medicinal materials is greater than the thickness of the wheat husk, which causes the wheat husk to be easily carbonized during the frying process. Therefore, it is necessary to screen and remove the carbonized wheat husk during the frying process to prevent the carbonized wheat husk from being mixed with the medicinal materials for a long time.

[0027] Beneficial effects of the present invention:

[0028] 1. Continuously transfer through the screening bucket, hollow cavity, uniform heat cavity and lift the receiving ring plate to the screening bucket for cyclic processing. On the one hand, the coked wheat husks in the medicinal materials are refined and screened. On the other hand, through the above circulation, the medicinal materials are heated by the screening bucket and then enter the top surface of the receiving ring plate for circulation, avoiding uneven heating caused by long-term heating of the medicinal materials. Through cyclic frying, the heating time and heat distribution of the medicinal materials will be more uniform, reducing local overheating and ensuring the quality of medicinal material preparation.

[0029] Second, by adding the medicinal materials that need to be fried, such as wheat husks and thick-sliced ​​medicinal materials, to the top of the screening bucket through the lower hopper, the wheat husks and medicinal materials that need to be fried enter the interior of the uniform heating chamber through the hollow cavity at the bottom of the screening bucket. At the same time, the rotating screening cylinder will drive the flip ring plate at its bottom to rotate and move on the side of the partition block, so that the wheat husks and medicinal materials on the top of the heating surface, that is, inside the uniform heating chamber, are periodically flipped on the top of the heating surface, reducing the uneven heating caused by the single side of the wheat husks and medicinal materials contacting the heating surface The pointed top protrusion of the heating surface will guide the fried wheat husks and medicinal materials on the top of the heating surface to move toward the top surface of the receiving ring plate, and the partition blocks arranged in a ring on the surface of the heating surface will temporarily block the heating of the wheat husks and medicinal materials on the surface of the heating surface, and the moving flip ring plate and the flow outlet will squeeze the fried wheat husks and medicinal materials that have been blocked by the partition blocks through the flow outlet along the surface curvature of the heating surface to the top surface of the receiving ring plate during the movement of the flip ring plate, thereby ensuring the heating time and effectiveness of the wheat husks and medicinal materials.

[0030] 3. When the top cover is snapped onto the top of the processing chamber, the height of the uniform heating chamber formed between the docking surface and the heating surface is limited, so that when the medicinal materials and wheat husks fall into the uniform heating chamber, the thickness of the medicinal materials and wheat husks is controlled, thereby facilitating the heating surface to heat and fry the medicinal materials and wheat husks inside the uniform heating chamber, thereby avoiding uneven heating caused by the accumulation of medicinal materials and wheat husks inside the uniform heating chamber.

[0031] Fourth, after the wheat husks and medicinal materials are heated and fried on the heating surface, they will enter the top of the receiving ring plate. The wheat husks and medicinal materials that have entered the top of the receiving ring plate will be driven by the rotation of the screening cylinder to cause the flip folding plate inside the vertical groove to rotate synchronously, so that the flip folding plate can be rotated and scraped on the surface of the receiving ring plate as the screening cylinder rotates, so that the thickness of the wheat husks and medicinal materials on the top surface of the receiving ring plate can be controlled, and the wheat husks inside the medicinal materials on the top of the receiving ring plate can be more flattened and exposed under the scraping of the flip folding plate, reducing the regional accumulation of wheat husks and medicinal materials on the surface of the receiving ring plate, which is convenient for the subsequent lifting of the receiving ring plate to process the carbonized wheat husks inside the medicinal materials.

[0032] 5. After the flipping folding plate scrapes and spreads the wheat husks and medicinal materials on the top surface of the receiving ring plate, the base pushing source is started, so that the base pushing source drives the receiving ring plate to move upward along the movable cavity outside the screening cylinder, and in this process, the flipping folding plate moves upward accordingly, and finally the flipping folding plate enters the inside of the through-hole, so that the wheat husks and medicinal materials on the top of the receiving ring plate collide with the impact ring plate, and after the collision, the impact ring plate will also rotate with the screening cylinder, so that the impact ring plate keeps rotating after the top surface of the receiving ring plate is pressed and hit, so that the wheat husks on the top of the impact ring plate and the carbonized wheat husks in the medicinal materials are lifted up by the receiving ring plate and hit by the impact ring plate, and the rotation and grinding of the impact ring plate relative to the receiving ring plate, so that the volume of the carbonized wheat husks is refined and reduced.

[0033] 6. Start the pushing material discharge source so that the output shaft of the pushing material discharge source pushes the pushing plate to move toward the center of the screening cylinder, so that the pushing plate pushes the wheat husks on the top surface of the receiving ring plate and the medicinal materials into the surface of the screening bucket during the movement, and the screening cylinder rotates accordingly, so that the wheat husks refined by the impact ring plate are driven by the rotation of the screening cylinder to generate the rotational centrifuge of the screening bucket, and the refined wheat husks pass through the screening holes on the surface of the screening bucket into the storage cavity for storage, thereby realizing the refined screening of the coked wheat husks during the frying of wheat husks and medicinal materials, and reducing the influence of excessive mixing of the coked wheat husks into the medicinal materials during the frying on the subsequent frying.

[0078] The rest of the structure is the same as that of the first embodiment.

[0079] Operation process:

[0080] When the wheat husks and medicinal materials are heated and fried by the heating surface 2024, they will enter the top of the receiving ring plate 2012. The wheat husks and medicinal materials that have entered the top of the receiving ring plate 2012 will be driven by the rotation of the screening cylinder 204 to cause the flip folding plate 206 inside the vertical groove 2041 to rotate synchronously, so that the flip folding plate 206 can rotate and scrape on the surface of the receiving ring plate 2012 as the screening cylinder 204 rotates, so that the thickness of the wheat husks and medicinal materials on the top surface of the receiving ring plate 2012 can be controlled, and the wheat husks inside the medicinal materials on the top of the receiving ring plate 2012 can be flattened and exposed more by the scraping of the flip folding plate 206, thereby reducing the regional accumulation of wheat husks and medicinal materials on the surface of the receiving ring plate 2012, so that it is convenient for the subsequent lifting of the receiving ring plate 2012 to process the wheat husks that have been fried and carbonized inside the medicinal materials.

[0081] It should be noted that the thickness of the flattening cavity 209 represents the thickness of the mixed fried wheat husks and medicinal materials on the top surface of the receiving ring plate 2012. The flip fold plate 206 can be lowered to the bottom of the vertical groove 2041 without being pushed by its own weight, and the bottom of the flip fold plate 206 can be in contact with the top surface of the heating surface 2024 for support, so that the heating surface 2024 supports the flip fold plate 206, so that a flattening cavity 209 for controlling the thickness of the wheat husks and medicinal materials on the top surface of the receiving ring plate 2012 is formed between the flip fold plate 206 and the receiving ring plate 2012. Of course, in order to better control the effect, such as Fig.10 As shown, a pushing and lifting source 2063 can also be installed on the top of the top cover 203, so that the output shaft of the pushing and lifting source 2063 controls the position of the flip folding plate 206 inside the vertical groove 2041 through the reciprocating rod 2062, so that the thickness of the flattening cavity 209, that is, the scraped thickness of the wheat husks and medicinal materials on the top of the receiving ring plate 2012, can be controlled.

[0082] After the flipping plate 206 scrapes and spreads the wheat husks and medicinal materials on the top surface of the receiving ring plate 2012, the base driving source 2011 is started, so that the base driving source 2011 drives the receiving ring plate 2012 to move upward along the moving cavity 205 outside the screening cylinder 204, and in this process, the flipping plate 206 moves upward accordingly, and finally the flipping plate 206 enters the inside of the through opening 20441, so that the wheat husks and medicinal materials on the top of the receiving ring plate 2012 collide with the impact ring plate 2044, and after the collision, the impact ring plate 2044 will also rotate with the screening cylinder 204, so that the impact ring plate 2044 After the top surface of the receiving ring plate 2012 is pressed and hit, it keeps rotating, so that the wheat husks on the top of the impact ring plate 2044 and the carbonized wheat husks in the medicinal materials are lifted up by the receiving ring plate 2012, hit by the impact ring plate 2044, and the rotation and grinding of the impact ring plate 2044 relative to the receiving ring plate 2012, so that the volume of the carbonized wheat husks is refined and reduced. After the impact ring plate 2044 rotates the receiving ring plate 2012 for a preset time, the receiving ring plate 2012 moves downward under the control of the base driving source 2011, so that the top surface of the receiving ring plate 2012 is flush with the top surface of the screening cylinder 204.

[0083] Of course, in order to stop the rotation of the screening cylinder 204 when the receiving ring plate 2012 is lifted, the impact ring plate 2044 will not rotate after the receiving ring plate 2012 and the impact ring plate 2044 collide, so that the volume of the carbonized wheat husks can be refined by the closed extrusion of the receiving ring plate 2012 and the impact ring plate 2044, so as to facilitate the subsequent screening bucket 2042 to screen the refined wheat husks. The thickness of the wheat husks is less than that of the thick-cut medicinal materials. Therefore, under the heating of the heating surface 2024, the carbonization of the wheat husks is earlier than that of the thick-cut medicinal materials. Therefore, when the receiving ring plate 2012 and the impact ring plate 2044 are closed and squeezed, the medicinal materials will not be excessively crushed, and in the initial stage of processing, the area of ​​the medicinal material slices is larger than the area of ​​the wheat husks. In the later stage after multiple cycles, if the medicinal materials are crushed, the volume will also be larger than the volume of the wheat husks before refinement. Of course, in order to further avoid the waste of medicinal materials, after the storage chamber 2046 stores a certain amount of refined wheat husks, the refined wheat husks inside it can be discharged through the discharge port 20461, and artificial screening can be carried out to screen out a small amount of fine medicinal materials and wheat husks inside, thereby further avoiding the waste of a small amount of medicinal materials during frying.

[0084] When the receiving ring plate 2012 is lifted up, the shielding member 20121 will be pulled up to seal the outside of the uniform heating chamber 208, so as to prevent the residual medicinal materials in the uniform heating chamber 208 from excessively flowing to the outside of the uniform heating chamber 208, i.e., the bottom of the movable chamber 205; when the receiving ring plate 2012 falls, the shielding member 20121 will be pressed down to the inside of the accommodating chamber 2022, so that the seal of the uniform heating chamber 208 is released.

[0085] When the top surface of the receiving ring plate 2012 is flush with the top of the screening cylinder 204, the pushing material source 2071 is started, so that the output shaft of the pushing material source 2071 pushes the pushing plate 2072 to move toward the center of the screening cylinder 204, so that the pushing plate 2072 pushes the wheat husks and medicinal materials on the top surface of the receiving ring plate 2012 into the surface of the screening bucket 2042 during the movement, and the screening cylinder 204 rotates accordingly, so that the wheat husks refined by the impact ring plate 2044 are driven by the rotation of the screening cylinder 204 to generate the rotation centrifugation of the screening bucket 2042, so that the refined wheat husks pass through the screening holes on the surface of the screening bucket 2042 and enter the storage chamber 2046 for storage, thereby realizing the refined screening of the coked wheat husks during the frying of wheat husks and medicinal materials, and reducing the influence of excessive mixing of the coked wheat husks into the medicinal materials during the frying on the subsequent frying;

[0086] Of course, the above process cannot fully guarantee that the coked wheat husks in the medicinal materials are completely screened out once. Therefore, it is necessary to repeat the above process a preset number of times to ensure that the influence of the coked wheat husks is reduced, and gradually increase the rotation speed of the screening cylinder 204 as the number of cycles of the above process increases, so that the flip ring plate 20471 squeezes and pushes the wheat husks and medicinal materials on the top surface of the screening cylinder 204 to speed up the speed, thereby avoiding multiple heating resulting in the heating time of the medicinal materials and wheat husks on the top surface of the heating surface 2024 being too long, and refining the screening process through multiple cycles of the above process. On the one hand, the content of coked wheat husks in the next frying cycle can be reduced, and on the other hand, the content of wheat husks in the medicinal materials can be gradually reduced through multiple cycles, thereby reducing the difficulty of screening after the wheat husks and medicinal materials are fried.

[0087] The continuous circulation through the screening bucket 2042, the hollow cavity 2045, the uniform heating cavity 208 and the lifting of the receiving ring plate 2012 to the screening bucket 2042 can, on the one hand, refine the screening of the coked wheat husks in the medicinal materials; on the other hand, through the above circulation, the medicinal materials are heated by the screening bucket 2042 and then enter the top surface of the receiving ring plate 2012 for circulation, thereby avoiding uneven heating caused by long-term heating of the medicinal materials. Through the circulation frying, the heating time and heat distribution of the medicinal materials will be more uniform, thereby reducing local overheating and ensuring the quality of the medicinal material preparation.

[0088] After the medicinal materials are fried for a preset time, the heating element 20232 and the processing rotating source 2031 are stopped, so that the top cover 203 is driven to open by the moving platform 104, thereby shoveling out the medicinal materials inside the processing cavity 202.

[0089] It should be noted that there are two ways for the flip folding plate 206 to move upward with the supporting ring plate 2012. When the top of the flip folding plate 206 is not equipped with a reciprocating rod 2062 controlled by a pushing and lifting source 2063, the supporting ring plate 2012 is lifted up to lift the flip folding plate 206 synchronously along the vertical groove 2041. If the top of the flip folding plate 206 is equipped with a reciprocating rod 2062 controlled by a pushing and lifting source 2063, the pushing and lifting source 2063 is synchronously contracted with the lifting of the base pushing source 2011, so that the pushing and lifting source 2063 pulls the flip folding plate 206 upward inside the vertical groove 2041 through the reciprocating rod 2062.
