Description

Technical Field

[0001] The present invention relates to the technical field of medicated diet food processing, and particularly to a device for removing impurities from the extraction and concentration liquid of raw materials for medicated diet food processing. Background Art

[0002] The concentrated liquid of medicated diet food refers to a liquid product made from raw and auxiliary materials that are both edible and medicinal or can be used in health foods according to traditional Chinese medicine theory and medicated diet formulas through modern food processing techniques such as extraction, filtration, concentration, and sterilization.

[0003] After retrieval, a Chinese patent with the publication number CN119657087A discloses an impurity removal device for a concentrated liquid of Qingtang tea saponin, including a device support column and a device housing fixedly installed at the top of the device support column. An inlet liquid column is arranged inside the device housing. The upper end of the inlet liquid column is provided with an inlet. A liquid storage tank is fixedly installed inside the device support column. A filtrate device is fixedly installed at the center of the top of the liquid storage tank. The bottom of the inlet liquid column is located at the center of the filtrate device. A filter mesh plate is arranged inside the filtrate device. A horizontal liquid distribution pipe and a vertical liquid distribution pipe are arranged at the top of the filter mesh plate. Through the coordinated action of the designed inlet liquid column, filtrate device, filter mesh plate, and filter agent embedding groove, the uniform penetration of the tea saponin concentrated liquid in the filter agent is realized, and the biological polysaccharide is effectively adsorbed and filtered by the composite filter agent, thus significantly increasing the proportion of pentacyclic triterpenoid saponins in the concentrated liquid.

[0004] In the above-mentioned prior art solution, through the coordinated action of the inlet liquid column, filtrate device, filter mesh plate, and filter agent embedding groove, the function of removing impurities in the material is realized. However, in the actual use process, some impurities have water absorption, so a certain amount of concentrated liquid will be contained in the impurities. During the process of removing impurities, the concentrated liquid adsorbed in the impurities is often easily overlooked, resulting in waste of the concentrated liquid. Summary of the Invention

[0005] To solve the above technical problems, the present invention proposes a device for removing impurities from the extraction and concentration liquid of raw materials for medicated diet food processing. The concentrated liquid to be processed is poured into the inside of the feeding tank. The concentrated liquid flows along the inner wall of the feeding tank into the inside of the processing tank. The impurities in the concentrated liquid are filtered through the filter mesh in the positioning frame. When the positioning frame rotates, the ejector rod can push the positioning frame upward, and the concentrated liquid between the partition cover and the filter mesh is thus squeezed, effectively extruding the remaining concentrated liquid therein, thereby avoiding the waste phenomenon of the concentrated liquid. The concentrated liquid with impurities filtered out is discharged outward through the discharge pipe.

A return spring is fixedly connected to the top wall surface of the pressing plate, the top end of the return spring is fixedly connected to the inner top wall surface of the receiving groove, and a sealing strip is fixedly installed on the bottom wall surface of the pressing plate.

[0014] In some embodiments, a return component is arranged outside the processing tank. The return component includes: An air flow pipe, the air flow pipe is rotatably connected to a nearby take-up reel through a bearing, an installation frame is fixedly installed on the side wall of the air flow pipe, hydraulic rods are fixedly installed on the side walls of the installation frame and the air storage frame, a connecting oil pipe is arranged outside the treatment tank, and the two hydraulic rods are interconnected through the connecting oil pipe. The extending end of the hydraulic rod on the installation frame is fixedly installed with a second piston plate, and the second piston plate is slidably installed inside the air flow pipe. A plurality of communication holes are provided on the side wall of the take-up reel corresponding to the air flow pipe; A return pipe, the return pipe is fixedly installed on the side wall of the air flow pipe, and the end of the return pipe away from the air flow pipe is fixedly installed on the side wall of the treatment tank. A one-way door is arranged inside the air flow pipe; A drainage frame, the drainage frame is fixedly installed on the inner side wall of the air flow pipe, and the air flow pipe is frustum-shaped.

[0015] In some embodiments, the air flow pipe is in a "C" shape. The hydraulic rod on the air storage frame has a larger radius. The extending end of the hydraulic rod on the air storage frame is fixedly installed on the side wall of a nearby first piston plate. The air flow pipe is communicated with the inside of the treatment tank through the return pipe. The top end of the one-way door is rotatably installed on the inner side wall of the air flow pipe, and the bottom end of the one-way door is inclined.

[0016] Compared with the prior art, the significant advantages of the present invention are: First: In the present invention, by opening the sealing cover and pouring the concentrated liquid to be treated into the inside of the feeding tank, the concentrated liquid flows along the inner side wall of the feeding tank into the inside of the treatment tank, and the impurities in the concentrated liquid are filtered through the filter screen to ensure the cleanliness of the concentrated liquid; through the mutual cooperation of the positioning chute and the positioning slider, the positioning frame can rotate synchronously with the driving shaft. Since the ejector rod is fixedly installed on the top of the positioning frame and the side wall of the guiding block is inclined, when the positioning frame rotates, the ejector rod can push the positioning frame upward, shortening the distance between the partition cover and the filter screen. The concentrated liquid between the partition cover and the filter screen is thus squeezed, accelerating the filtering speed of the concentrated liquid. By rotating the adjusting screw to adjust the height of the positioning frame, when the filter screen moves upward, the impurities on the surface of the filter screen can be effectively extruded of the remaining concentrated liquid through the extrusion of the partition cover, thus avoiding the waste phenomenon of the concentrated liquid. The concentrated liquid with impurities filtered out is discharged outward through the discharge pipe; it solves the problem that the concentrated liquid in the existing impurities is wasted.

[0017] Second: In the present invention, by passing a filter cloth through the inside of the treatment tank, the filter cloth further filters the concentrated liquid, further reducing the impurities in the concentrated liquid. The part of the filter cloth passing through the treatment tank is located at the bottom of the take-up reel. When the take-up reel winds up the filter cloth, it can wrap up the impurities on the surface of the filter cloth, facilitating the collection of the impurities. At the same time, the filter cloth will be squeezed when it is wound up, and the concentrated liquid accumulated on the filter cloth is thus extruded and flows back to the inside of the treatment tank through the return frame, further avoiding the waste of the concentrated liquid.

[0018] Thirdly: In the present invention, when the drive shaft drives the positioning frame to rotate, the guiding block will contact the side wall of the sliding rod and push the sliding rod to move downward. As a result, the linkage block will push the extrusion block and the piston plate I to move into the interior of the air storage frame, sucking the air inside the treatment tank into the interior of the air storage frame. The top end inside the treatment tank is sealed by the partition cover. Therefore, negative pressure is generated at the bottom end inside the treatment tank, causing the concentrated liquid on the surface of the filter cloth to accelerate through the filter cloth under the action of the pressure difference, while the impurities in the concentrated liquid are intercepted on the surface of the filter cloth, improving the filtering speed of the filter cloth.

[0019] Fourthly: In the present invention, by utilizing the elasticity of the return spring, the pressing plate is pulled upward to create a gap between the pressing plate and the filter cloth, facilitating the winding of the filter cloth. When the positioning frame moves downward, the distance between the second magnet and the first magnet is shortened, and under the influence of magnetism, the push rod and the pressing plate are pushed downward to press the filter cloth, ensuring that the interior of the treatment tank is in a sealed state, facilitating the air extraction assembly to extract the air inside the treatment tank; the pressure applied by the pressing plate on the side wall of the filter cloth is buffered by the sealing strip, and at the same time, the gaps on the filter cloth are filled, improving the sealing effect of the sealing assembly.

[0020] Fifthly: In the present invention, when the movement of the piston plate I drives the extension end of the hydraulic rod to extend, the extension end of the mounting frame on the mounting frame contracts, and as a result, the piston plate II moves, causing negative pressure to be generated inside the mounting frame and the air flow pipe. The concentrated liquid on the filter cloth is thus sucked into the interior of the air flow pipe through the communication holes, further treating the residual concentrated liquid on the filter cloth and avoiding waste of the concentrated liquid. When the movement of the piston plate I drives the extension end of the hydraulic rod to contract, the extension end of the mounting frame on the mounting frame extends, and as a result, the piston plate II pushes the concentrated liquid inside the air flow pipe to move into the interior of the return pipe, causing the concentrated liquid to flow back into the interior of the treatment tank.

A filter screen 28 is fixedly mounted on the inner side wall of the positioning frame 26, and a reinforcing frame 27 is fixedly mounted on the inner side wall of the positioning frame 26; the strength inside the positioning frame 26 is increased through the reinforcing frame 27; By opening the sealing cover 22, the concentrated liquid to be processed is poured into the interior of the feeding tank 21. The concentrated liquid flows along the inner side wall of the feeding tank 21 into the interior of the processing tank 1, and impurities in the concentrated liquid are filtered through the filter screen 28 to ensure the cleanliness of the concentrated liquid; The positioning frame 25 is fixedly mounted on the inner side wall of the processing tank 1, and the bottom end of the drive shaft 24 is rotatably mounted on the side wall of the positioning frame 25; The position of the drive shaft 24 is reinforced through the positioning frame 25 to ensure the stability of the position of the drive shaft 24; A positioning assembly is provided at the top of the processing tank 1. The positioning assembly includes a sliding frame 31, a fixed frame 33, a partition cover 35, and a positioning rod 34; The sliding frame 31 slidably penetrates the top wall surface of the feeding tank 21, and an adjusting screw 32 threadedly penetrates the top wall surface of the sliding frame 31; The fixed frame 33 is fixedly mounted on the top wall surface of the feeding tank 21, and the bottom end of the adjusting screw 32 is located inside the fixed frame 33; The partition cover 35 is slidably mounted on the side wall of the drive shaft 24, and the bottom wall surface of the sliding frame 31 is fixedly mounted on the top wall surface of the partition cover 35; The positioning rod 34 slidably penetrates the side wall of the fixed frame 33, and the positioning rod 34 penetrates the side wall of the adjusting screw 32; By penetrating the side walls of the fixed frame 33 and the adjusting screw 32 with the positioning rod 34, the positions of the sliding frame 31 and the partition cover 35 are fixed to prevent the partition cover 35 from easily sliding up and down; An ejection assembly is provided inside the processing tank 1. The ejection assembly includes a top rod 41, a guiding block 42, a positioning chute 44, and a compression spring 43; There are multiple top rods 41 and guiding blocks 42. Multiple top rods 41 are fixedly mounted on the top wall surface of the positioning frame 25, and multiple guiding blocks 42 are fixedly mounted on the bottom wall surface of the reinforcing frame 27. The position of the guiding block 42 is aligned with the position of the top rod 41, and the side wall of the guiding block 42 is inclined; The positioning chute 44 is opened on the side wall of the drive shaft 24, and a positioning slider 45 is slidably mounted inside the positioning chute 44. The positioning slider 45 is fixedly mounted on the inner side wall of the positioning frame 26; The compression spring 43 is sleeved on the bottom end of the side wall of the drive shaft 24, and the upper and lower ends of the compression spring 43 are respectively fixedly connected to the bottom end of the positioning frame 26 and the top end of the positioning frame 25; By utilizing the elasticity of the contraction spring 43, the force for the downward movement of the positioning frame 26 is increased, the impact force between the positioning frame 26 and the ejector rod 41 is enhanced, enabling the filter screen 28 to vibrate sufficiently, facilitating the flow of the concentrated liquid on the surface of the filter screen 28; Through the mutual cooperation of the positioning chute 44 and the positioning slider 45, the positioning frame 26 can rotate synchronously with the driving shaft 24. Since the ejector rod 41 is fixedly installed at the top of the positioning frame 25 and the side wall of the guiding block 42 is inclined, when the positioning frame 26 rotates, the ejector rod 41 can push the positioning frame 26 upward, shortening the distance between the partition cover 35 and the filter screen 28. And the partition cover 35 remains fixed in position under the restriction of the sliding frame 31, the adjusting screw 32 and the fixing frame 33. The concentrated liquid between the partition cover 35 and the filter screen 28 is thus squeezed, accelerating the filtration speed of the concentrated liquid. By rotating the adjusting screw 32 to adjust the height of the positioning frame 25, when the filter screen 28 moves upward, the impurities on the surface of the filter screen 28 can be effectively extruded of the remaining concentrated liquid through the extrusion of the partition cover 35, thereby avoiding the waste phenomenon of the concentrated liquid. The concentrated liquid filtered from the impurities is discharged outward through the discharge pipe 9.

[0025] As Figures 2-6 shown, in an embodiment, a filtering assembly is provided at the bottom of the feeding tank 21. The filtering assembly includes a mounting frame 51, a filter cloth 55 and a return flow frame 56; There are two mounting frames 51 in total. The two mounting frames 51 are respectively fixedly installed on both sides of the processing tank 1. Sealing doors 52 are rotatably installed on the side wall surfaces of the two mounting frames 51 away from each other. Reel drums 54 are rotatably installed inside the two mounting frames 51. A winding motor 53 is fixedly installed on the side wall of the mounting frame 51. The output shaft of the winding motor 53 is fixedly connected to the inner side wall of the adjacent reel drum 54; By the rotation of the winding motor 53, it is convenient to wind the filter cloth 55; The filter cloth 55 penetrates through the inner side wall of the processing tank 1, and both ends of the filter cloth 55 are wound around the side wall of the reel drum 54. The filter cloth 55 is located at the bottom end of the filter screen 28; By penetrating the filter cloth 55 inside the processing tank 1, the filter cloth 55 further filters the concentrated liquid, further reducing the impurities in the concentrated liquid; The return flow frame 56 is fixedly installed on the side wall of the processing tank 1. The top wall surface of the return flow frame 56 is fixedly installed on the bottom wall surface of the mounting frame 51. The return flow frame 56 is located at the bottom of the reel drum 54 for collection, and the part of the filter cloth 55 passing through the processing tank 1 is located at the bottom of the reel drum 54; By arranging the part of the filter cloth 55 passing through the treatment tank 1 at the bottom of the winding drum 54, when the winding drum 54 winds up the filter cloth 55, the impurities on the surface of the filter cloth 55 can be wrapped up, facilitating the collection of the impurities. At the same time, when the filter cloth 55 is wound up, it will be squeezed, and the concentrated liquid accumulated on the filter cloth 55 is thus squeezed out and flows back into the interior of the treatment tank 1 through the return frame 56, further avoiding the waste of the concentrated liquid; An air extraction component is arranged inside the treatment tank 1, and the air extraction component includes an air storage frame 61, a positioning block 65 and a pressing block 64; The air storage frame 61 is fixedly installed on the side wall of the treatment tank 1.

By the bearing plate 68, the filter cloth 55 is supported, avoiding the situation where the filter cloth 55 deforms due to receiving the concentrated liquid and affecting the filtration; The pressing block 64 is fixedly installed on the side wall surface of the first piston plate 62 close to the treatment tank 1.

The top end of the sliding rod 66 slidably penetrates through the inside of the positioning block 65, and the sliding rod 66 is aligned with the guiding block 42; When the driving shaft 24 drives the positioning frame 26 to rotate, the guiding block 42 will contact the side wall of the sliding rod 66 and push the sliding rod 66 to move downward. Therefore, the linkage block 67 will push the pressing block 64 and the first piston plate 62 to move into the air storage frame 61, sucking the air inside the treatment tank 1 into the air storage frame 61. The top end inside the treatment tank 1 is sealed by the partition cover 35. Therefore, negative pressure is generated at the bottom end inside the treatment tank 1, causing the concentrated liquid on the surface of the filter cloth 55 to accelerate through the filter cloth 55 under the action of the pressure difference, and the impurities in the concentrated liquid are intercepted on the surface of the filter cloth 55, improving the filtration speed of the filter cloth 55.

A sealing strip 77 is fixedly installed on the bottom wall surface of the pressing plate 72; By utilizing the elasticity of the reset spring 73, the pressing plate 72 is pulled upward to create a gap between the pressing plate 72 and the filter cloth 55, facilitating the winding of the filter cloth 55. When the positioning frame 26 moves downward, the distance between the second magnet 76 and the first magnet 75 is shortened, and under the influence of magnetism, the push rod 74 and the pressing plate 72 are pushed downward to press the filter cloth 55, ensuring that the inside of the treatment tank 1 is in a sealed state, facilitating the air extraction assembly to extract the air inside the treatment tank 1; The sealing strip 77 buffers the pressure exerted by the pressing plate 72 on the side wall of the filter cloth 55 and fills the gaps on the filter cloth 55 at the same time, improving the sealing effect of the sealing assembly.

A connecting oil pipe 82 is arranged outside the treatment tank 1. The two hydraulic rods 81 are interconnected through the connecting oil pipe 82. The extended end of the hydraulic rod 81 on the installation frame 83 is fixedly installed with a second piston plate 85. The second piston plate 85 is slidably installed inside the air flow pipe 84. A plurality of communication holes 86 are formed on the side wall of the winding drum 54 corresponding to the air flow pipe 84; When the movement of the first piston plate 62 drives the extended end of the hydraulic rod 81 to extend, the extended end of the installation frame 83 on the installation frame 83 contracts, and the second piston plate 85 moves accordingly, creating a negative pressure inside the installation frame 51 and the air flow pipe 84. The concentrated liquid on the filter cloth 55 is thus sucked into the inside of the air flow pipe 84 through the communication holes 86, further treating the residual concentrated liquid on the filter cloth 55 and avoiding the waste of the concentrated liquid; The return pipe 88 is fixedly installed on the side wall of the air flow pipe 84, and one end of the return pipe 88 far away from the air flow pipe 84 is fixedly installed on the side wall of the treatment tank 1. The air flow pipe 84 is internally communicated with the treatment tank 1 through the return pipe 88. A check valve 89 is arranged inside the air flow pipe 84. The top end of the check valve 89 is rotatably installed on the inner side wall of the air flow pipe 84, and the bottom end of the check valve 89 is inclined; When the movement of the piston plate 62 drives the extension end of the hydraulic rod 81 to contract, the extension end of the mounting bracket 83 on the mounting bracket 83 extends. Therefore, the piston plate 85 pushes the concentrated liquid inside the air flow pipe 84 to move into the return pipe 88, so that the concentrated liquid flows back into the treatment tank 1. Since the top end of the check valve 89 is rotatably installed inside the air flow pipe 84, when the check valve 89 no longer receives a thrust force, the check valve 89 rotates downward due to the influence of gravity to seal the connection between the return pipe 88 and the air flow pipe 84. And the bottom end of the check valve 89 is inclined. When there is negative pressure inside the air flow pipe 84, the inclined side wall at the bottom end of the check valve 89 will prevent the check valve 89 from rotating into the air flow pipe 84, ensuring that the inside of the air flow pipe 84 is in a sealed state, which is convenient for sucking the concentrated liquid inside the filter cloth 55 into the air flow pipe 84; The drainage frame 87 is fixedly installed on the inner side wall of the air flow pipe 84, and the air flow pipe 84 is frustum-shaped; By the air flow pipe 84, the communication area between the bottom end and the top end of the air flow pipe 84 is reduced, avoiding the situation that the concentrated liquid flows back into the installation frame 51 during the process of the piston plate 85 pushing the concentrated liquid into the return pipe 88.

[0028] The specific working method is as follows: Open the sealing cover 22, pour the concentrated liquid to be processed into the interior of the feeding tank 21. The concentrated liquid flows into the interior of the processing tank 1 along the inner side wall of the feeding tank 21, and the impurities in the concentrated liquid are filtered by the filter screen 28 to ensure the cleanliness of the concentrated liquid. Through the mutual cooperation of the positioning chute 44 and the positioning slider 45, the positioning frame 26 can rotate synchronously with the driving shaft 24. Since the ejector rod 41 is fixedly installed at the top of the positioning frame 25 and the side wall of the guiding block 42 is inclined, when the positioning frame 26 rotates, the ejector rod 41 can push the positioning frame 26 upward, shortening the distance between the partition cover 35 and the filter screen 28. And the partition cover 35 is fixed in position under the restriction of the sliding frame 31, the adjusting screw rod 32 and the fixing frame 33. The concentrated liquid between the partition cover 35 and the filter screen 28 is thus squeezed, accelerating the filtering speed of the concentrated liquid. By rotating the adjusting screw rod 32 to adjust the height of the positioning frame 25, when the filter screen 28 moves upward, the impurities on the surface of the filter screen 28 can be effectively extruded of the residual concentrated liquid therein through the extrusion of the partition cover 35, thus avoiding the waste of concentrated liquid. The part of the filter cloth 55 passing through the processing tank 1 is located at the bottom of the winding drum 54. When the winding drum 54 winds up the filter cloth 55, the impurities on the surface of the filter cloth 55 can be wrapped up, facilitating the collection of the impurities. At the same time, the filter cloth 55 will be squeezed when being wound up, and the concentrated liquid accumulated on the filter cloth 55 is thus extruded and flows back to the interior of the processing tank 1 through the return frame 56, further avoiding the waste of concentrated liquid. When the driving shaft 24 drives the positioning frame 26 to rotate, the guiding block 42 will contact the side wall of the sliding rod 66 and push the sliding rod 66 downward. The linkage block 67 will thus push the extrusion block 64 and the piston plate one 62 into the interior of the air storage frame 61, sucking the air inside the processing tank 1 into the interior of the air storage frame 61. The top end inside the processing tank 1 is sealed by the partition cover 35. Therefore, negative pressure is generated at the bottom end inside the processing tank 1, causing the concentrated liquid on the surface of the filter cloth 55 to accelerate through the filter cloth 55 under the action of the pressure difference, while the impurities in the concentrated liquid are intercepted on the surface of the filter cloth 55, improving the filtering speed of the filter cloth 55. When the movement of the piston plate one 62 drives the extension end of the hydraulic rod 81 to extend, the extension end of the mounting frame 83 on the mounting frame 83 contracts. The piston plate two 85 thus moves, causing negative pressure to be generated inside the mounting frame 51 and the air flow pipe 84. The concentrated liquid on the filter cloth 55 is thus sucked into the interior of the air flow pipe 84 through the communication hole 86, further processing the residual concentrated liquid on the filter cloth 55 and avoiding the waste of concentrated liquid. When the movement of the piston plate one 62 drives the extension end of the hydraulic rod 81 to contract, the extension end of the mounting frame 83 on the mounting frame 83 extends. The piston plate two 85 thus pushes the concentrated liquid inside the air flow pipe 84 to move into the interior of the return pipe 88, causing the concentrated liquid to flow back to the interior of the processing tank 1. Since the top end of the one-way door 89 is rotatably installed inside the air flow pipe 84, when the one-way door 89 no longer receives a thrust force, the one-way door 89 rotates downward due to the influence of gravity to seal the connection between the return pipe 88 and the air flow pipe 84.Moreover, the bottom end of the one-way door 89 is inclined. When there is negative pressure inside the air flow pipe 84, the inclined side wall at the bottom end of the one-way door 89 will prevent the one-way door 89 from rotating towards the inside of the air flow pipe 84, ensuring that the inside of the air flow pipe 84 is in a sealed state, facilitating the suction of the concentrated liquid inside the filter cloth 55 into the inside of the air flow pipe 84, and discharging the concentrated liquid filtered of impurities through the discharge pipe 9.
