[0040] Compared with the prior art, the present invention has the following significant advantages:

[0041] First, the present invention opens the sealing cover and pours the concentrated liquid to be processed into the interior of the feeding tank. The concentrated liquid flows into the interior of the processing tank along the inner wall of the feeding tank, and the impurities in the concentrated liquid are filtered through the filter screen to ensure that the concentrated liquid is clean; through the mutual cooperation of the positioning slide and the positioning slider, the positioning frame can rotate synchronously with the drive shaft. Since the push rod is fixedly installed on the top of the positioning frame and the side wall of the guide block is inclined, when the positioning frame rotates, the push rod can push the positioning frame to move upward, shortening the distance between the partition cover and the filter screen. The concentrated liquid between the partition cover and the filter screen is therefore squeezed, thereby accelerating the filtration 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 squeezed by the partition cover, and the residual concentrated liquid therein can be effectively squeezed out, thereby avoiding the waste of concentrated liquid, and the concentrated liquid with impurities filtered out is discharged outwardly through the discharge pipe; the problem of waste of concentrated liquid in the existing impurities is solved.

[0042] Secondly, the present invention allows the filter cloth to penetrate the interior of the treatment tank, so that the filter cloth can further filter the concentrated liquid and further reduce the impurities in the concentrated liquid. By locating the portion of the filter cloth that passes through the treatment tank at the bottom of the winding drum, when the winding drum rolls up the filter cloth, the impurities on the surface of the filter cloth can be wrapped up, which is convenient for collecting the impurities. At the same time, the filter cloth will be squeezed when it is rolled up, and the concentrated liquid accumulated on the filter cloth will be squeezed out and reflux to the interior of the treatment tank through the reflux frame, further avoiding the waste of the concentrated liquid.

[0043] Third: In the present invention, when the driving shaft drives the positioning frame to rotate, the guide block will contact the side wall of the sliding rod, pushing the sliding rod to move downward, and the linkage block will therefore push the extrusion block and the piston plate to move toward the inside of the air storage frame, sucking the air inside the processing tank into the interior of the air storage frame. The internal top of the processing tank is sealed by the partition cover, so that the internal bottom end of the processing tank generates negative pressure, so that the concentrated liquid on the surface of the filter cloth is accelerated to pass through the filter cloth under the action of the pressure difference, and the impurities in the concentrated liquid are trapped on the surface of the filter cloth, thereby improving the filtration speed of the filter cloth.

[0044] Fourthly, the present invention utilizes the elasticity of the return spring to pull the pressing plate upward, so that there is a gap between the pressing plate and the filter cloth, which is convenient for winding the filter cloth; when the positioning frame moves downward, the distance between the second magnetic block and the first magnetic block 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 processing tank is in a sealed state, which is convenient for the exhaust component to extract the air inside the processing tank; the pressure applied by the pressing plate to the side wall of the filter cloth is buffered by the sealing strip, and the gap on the filter cloth is filled at the same time, thereby improving the sealing effect of the sealing component.

[0045] Fifth: In the present invention, when the movement of piston plate one drives the extended end of the hydraulic rod to extend, the extended end of the mounting bracket on the mounting bracket contracts, and piston plate two moves accordingly, so that negative pressure is generated inside the mounting frame and the airflow tube, and the concentrated liquid on the filter cloth is therefore sucked into the interior of the airflow tube through the connecting hole, and the concentrated liquid remaining on the filter cloth is further processed to avoid waste of the concentrated liquid. When the movement of piston plate one drives the extended end of the hydraulic rod to contract, the extended end of the mounting bracket on the mounting bracket extends, and piston plate two pushes the concentrated liquid inside the airflow tube to move toward the interior of the reflux tube, so that the concentrated liquid flows back to the interior of the treatment tank.

[0056] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] The present invention provides an improved device for removing impurities from raw material extract concentrate for medicinal food processing. The technical solution of the present invention is:

[0058] like Figure 1-Figure 5 As shown, a device for removing impurities from raw material extract concentrate for medicinal food processing includes a processing tank 1, a plurality of support legs are fixedly installed on the bottom wall of the processing tank 1, a discharge pipe 9 is fixedly installed on the bottom wall of the processing tank 1, a sealing plug is provided inside the discharge pipe 9, and a discharge assembly is provided on the top of the processing tank 1, which includes a feeding tank 21, a driving motor 23, a positioning frame 26 and a positioning frame 25;

[0059] The feeding tank 21 is fixedly mounted on the top wall of the treatment tank 1. The side wall of the feeding tank 21 is inclined. A sealing cover 22 is clamped on the top wall of the feeding tank 21.

[0060] The drive motor 23 is fixedly mounted on the top wall of the feeding tank 21. The output shaft of the drive motor 23 is fixedly mounted with a drive shaft 24. The bottom end of the drive shaft 24 passes through the interior of the feeding tank 21 and extends to the interior of the processing tank 1.

[0061] The positioning frame 26 is slidably mounted on the side wall of the drive shaft 24. A filter screen 28 is fixedly mounted on the inner side wall of the positioning frame 26. A reinforcement frame 27 is fixedly mounted on the inner side wall of the positioning frame 26. The reinforcement frame 27 improves the internal strength of the positioning frame 26.

[0062] 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 into the interior of the processing tank 1 along the inner wall of the feeding tank 21. The impurities in the concentrated liquid are filtered through the filter 28 to ensure that the concentrated liquid is clean.

[0063] The positioning frame 25 is fixedly mounted on the inner side wall of the processing tank 1, and the bottom end of the driving shaft 24 is rotatably mounted on the side wall of the positioning frame 25;

[0064] The position of the drive shaft 24 is reinforced by the positioning frame 25 to ensure the stability of the position of the drive shaft 24;

[0065] A positioning assembly is provided on the top of the processing tank 1, and the positioning assembly includes a sliding frame 31, a fixed frame 33, a partition cover 35 and a positioning rod 34;

[0066] The sliding frame 31 slides through the top wall of the feeding tank 21, and the top wall of the sliding frame 31 is threaded with an adjusting screw 32;

[0067] The fixing bracket 33 is fixedly mounted on the top wall of the feeding tank 21, and the bottom end of the adjusting screw 32 is located inside the fixing bracket 33;

[0068] The partition cover 35 is slidably mounted on the side wall of the drive shaft 24 , and the bottom wall of the sliding frame 31 is fixedly mounted on the top wall of the partition cover 35 ;

[0069] The positioning rod 34 slides through the side wall of the fixing frame 33, and the positioning rod 34 passes through the side wall of the adjusting screw 32;

[0070] By inserting the positioning rod 34 through the side wall of the fixing frame 33 and the adjusting screw 32, the position of the sliding frame 31 and the partition cover 35 is fixed to prevent the partition cover 35 from sliding up and down easily;

[0071] The interior of the processing tank 1 is provided with an ejection assembly, which includes an ejector rod 41, a guide block 42, a positioning slide 44 and a contraction spring 43;

[0072] There are multiple push rods 41 and guide blocks 42. Multiple push rods 41 are fixedly mounted on the top wall of the positioning frame 25, and multiple guide blocks 42 are fixedly mounted on the bottom wall of the reinforcement frame 27. The positions of the guide blocks 42 are aligned with the positions of the push rods 41, and the side walls of the guide blocks 42 are inclined.

[0073] The positioning slot 44 is formed on the side wall of the drive shaft 24 , and a positioning slider 45 is slidably mounted inside the positioning slot 44 . The positioning slider 45 is fixedly mounted on the inner side wall of the positioning frame 26 .

[0074] The contraction 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 contraction spring 43 are fixedly connected to the bottom end of the positioning frame 26 and the top end of the positioning frame 25 respectively;

[0075] By utilizing the elasticity of the contraction spring 43, the downward force of the positioning frame 26 is increased, and the impact force between the positioning frame 26 and the push rod 41 is increased, so that the filter 28 is fully vibrated, which facilitates the flow of the concentrated liquid on the surface of the filter 28;

[0076] Through the mutual cooperation of the positioning slide 44 and the positioning slider 45, the positioning frame 26 can rotate synchronously with the drive shaft 24. Since the push rod 41 is fixedly installed on the top of the positioning frame 25 and the side wall of the guide block 42 is inclined, when the positioning frame 26 rotates, the push rod 41 can push the positioning frame 26 to move 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 therefore squeezed, thereby accelerating the filtration speed of the concentrated liquid. By adjusting the height of the positioning frame 25 by rotating the adjusting screw 32, when the filter screen 28 moves upward, the impurities on the surface of the filter screen 28 can be squeezed by the partition cover 35, and the residual concentrated liquid therein can be effectively squeezed out, thereby avoiding the waste of concentrated liquid, and the concentrated liquid with impurities filtered out is discharged outward through the discharge pipe 9.

[0077] like Figure 2-Figure 6 As shown, in one embodiment, a filter assembly is provided at the bottom of the feeding tank 21, and the filter assembly includes a mounting frame 51, a filter cloth 55 and a reflux frame 56;

[0078] There are two mounting frames 51, which are fixedly mounted on both sides of the processing tank 1. A sealing door 52 is rotatably mounted on the wall surface of each mounting frame 51 that is away from each other. A winding drum 54 is rotatably mounted inside each mounting frame 51. A winding motor 53 is fixedly mounted on the side wall of the mounting frame 51, and the output shaft of the winding motor 53 is fixedly connected to the inner wall of the adjacent winding drum 54.

[0079] The filter cloth 55 is easily wound by the rotation of the winding motor 53;

[0080] The filter cloth 55 passes through the inner wall of the treatment tank 1, and the two ends of the filter cloth 55 are wound around the side wall of the winding drum 54. The filter cloth 55 is located at the bottom end of the filter screen 28;

[0081] By passing the filter cloth 55 through the interior of the treatment tank 1, the filter cloth 55 further filters the concentrated liquid, thereby further reducing impurities in the concentrated liquid;

[0082] The reflux frame 56 is fixedly mounted on the side wall of the treatment tank 1, and the top wall of the reflux frame 56 is fixedly mounted on the bottom wall of the mounting frame 51. The reflux frame 56 is located at the bottom of the winding drum 54 for collection, and the portion of the filter cloth 55 that passes through the treatment tank 1 is located at the bottom of the winding drum 54.

[0083] By positioning the portion of the filter cloth 55 passing through the treatment tank 1 at the bottom of the take-up drum 54, when the take-up drum 54 rolls up the filter cloth 55, impurities on the surface of the filter cloth 55 can be wrapped up, making it easier to collect the impurities. At the same time, the filter cloth 55 is squeezed when it is rolled up, and the concentrated liquid accumulated on the filter cloth 55 is squeezed out and flows back into the treatment tank 1 through the reflux frame 56, further avoiding waste of the concentrated liquid.

[0084] The processing tank 1 is provided with an exhaust assembly inside, which includes an air storage frame 61, a positioning block 65 and an extrusion block 64;

[0085] The gas storage frame 61 is fixedly mounted on the side wall of the processing tank 1. The gas storage frame 61 is in communication with the interior of the processing tank 1. A piston plate 62 is slidably mounted inside the gas storage frame 61. An extrusion spring 63 is fixedly connected to the inner side wall of the gas storage frame 61. The extrusion spring 63 is fixedly connected to the side wall of the piston plate 62.

[0086] By utilizing the elasticity of the extrusion spring 63, the piston plate 1 62 is conveniently pushed toward the interior of the processing tank 1;

[0087] The positioning block 65 is fixedly mounted on the inner side wall of the treatment tank 1. A bearing plate 68 is fixedly mounted on the side wall of the positioning block 65. The bearing plate 68 is located at the bottom of the filter cloth 55. The side wall of the positioning block 65 is in contact with the side wall of the filter cloth 55.

[0088] The gap between the filter cloth 55 and the inner wall of the treatment tank 1 is filled by the positioning block 65 to prevent the concentrated liquid from not being filtered. The filter cloth 55 is supported by the bearing plate 68 to prevent the concentrated liquid from deforming and affecting the filtration.

[0089] The extrusion block 64 is fixedly mounted on the side wall of the piston plate 1 62 close to the processing tank 1. The side wall of the extrusion block 64 is inclined. A linkage block 67 is attached to the side wall of the extrusion block 64. A sliding rod 66 is fixedly mounted on the top wall of the linkage block 67. The top end of the sliding rod 66 slides through the interior of the positioning block 65, and the sliding rod 66 is aligned with the position of the guide block 42.

[0090] When the driving shaft 24 drives the positioning frame 26 to rotate, the guide block 42 will contact the side wall of the sliding rod 66, pushing the sliding rod 66 to move downward, and the linkage block 67 will therefore push the extrusion block 64 and the piston plate 62 to move toward the inside of the air storage frame 61, sucking the air inside the processing tank 1 into the interior of the air storage frame 61. The inner top of the processing tank 1 is sealed by the partition cover 35, so that the inner bottom end of the processing tank 1 generates a negative pressure, so that the concentrated liquid on the surface of the filter cloth 55 is accelerated to pass through the filter cloth 55 under the action of the pressure difference, and the impurities in the concentrated liquid are trapped on the surface of the filter cloth 55, thereby improving the filtration speed of the filter cloth 55.

[0091] like Figure 2-Figure 6 As shown, in one embodiment, a sealing assembly is provided inside the processing tank 1, and the sealing assembly includes a receiving groove 71 and a push rod 74;

[0092] There are two receiving grooves 71, both of which are opened on the side wall of the processing tank 1, and the receiving grooves 71 correspond to the filter cloth 55. A pressing plate 72 is slidably installed inside the receiving groove 71, and a return spring 73 is fixedly connected to the top wall of the pressing plate 72. The top end of the return spring 73 is fixedly connected to the top wall of the receiving groove 71.

[0093] A push rod 74 is disposed inside the processing tank 1 and is fixedly mounted on the side wall of the pressing plate 72. A first magnet 75 is fixedly mounted on the top wall of the push rod 74. A second magnet 76 is disposed on the top of the first magnet 75. The second magnet 76 is fixedly mounted on the bottom wall of the positioning frame 26. The adjacent ends of the first magnet 75 and the second magnet 76 have the same magnetic poles. A sealing strip 77 is fixedly mounted on the bottom wall of the pressing plate 72.

[0094] By utilizing the elasticity of the return spring 73, the pressing plate 72 is pulled upward to create a gap between the pressing plate 72 and the filter cloth 55, which is convenient for winding up the filter cloth 55. When the positioning frame 26 moves downward, the distance between the second magnetic block 76 and the first magnetic block 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 interior of the processing tank 1 is in a sealed state, which is convenient for the exhaust component to extract the air inside the processing tank 1; the pressure applied by the pressing plate 72 to the side wall of the filter cloth 55 is buffered by the sealing strip 77, and at the same time, the gap on the filter cloth 55 is filled to improve the sealing effect of the sealing component.

[0095] like Figure 2-Figure 7 As shown, in one embodiment, a reflux assembly is provided outside the processing tank 1, and the reflux assembly includes an air flow pipe 84, a reflux pipe 88 and a drainage frame 87;

[0096] The airflow tube 84 is rotatably connected to the adjacent winding drum 54 through a bearing. The airflow tube 84 is in a "C" shape. A mounting bracket 83 is fixedly mounted on the side wall of the airflow tube 84. Hydraulic rods 81 are fixedly mounted on the mounting bracket 83 and the side wall of the gas storage frame 61. The radius of the hydraulic rod 81 located on the gas storage frame 61 is larger. The extended end of the hydraulic rod 81 on the gas storage frame 61 is fixedly mounted on the side wall of the adjacent piston plate 1 62. A connecting oil pipe 82 is provided on the outside of the processing tank 1. The two hydraulic rods 81 are connected to each other through the connecting oil pipe 82. A piston plate 2 85 is fixedly mounted on the extended end of the hydraulic rod 81 on the mounting bracket 83. The piston plate 2 85 is slidably mounted on the inside of the airflow tube 84. A plurality of connecting holes 86 are provided on the side wall of the winding drum 54 corresponding to the airflow tube 84.

[0097] When the movement of the piston plate 1 62 drives the extension end of the hydraulic rod 81 to extend, the extension end of the mounting bracket 83 on the mounting bracket 83 contracts, and the piston plate 2 85 moves accordingly, so that negative pressure is generated inside the mounting frame 51 and the air flow tube 84. The concentrated liquid on the filter cloth 55 is thus sucked into the air flow tube 84 through the connecting hole 86, and the concentrated liquid remaining on the filter cloth 55 is further processed to avoid waste of the concentrated liquid.

[0098] The return pipe 88 is fixedly mounted on the side wall of the airflow pipe 84, and the end of the return pipe 88 away from the airflow pipe 84 is fixedly mounted on the side wall of the treatment tank 1. The airflow pipe 84 is connected to the interior of the treatment tank 1 through the return pipe 88. A one-way door 89 is provided inside the airflow pipe 84. The top end of the one-way door 89 is rotatably mounted on the inner side wall of the airflow pipe 84, and the bottom end of the one-way door 89 is inclined.

[0099] When the piston plate 1 62 moves and the extended end of the hydraulic rod 81 contracts, the extended end of the mounting bracket 83 on the mounting bracket 83 extends, and the piston plate 2 85 pushes the concentrated liquid in the air flow tube 84 to move into the inside of the return pipe 88, so that the concentrated liquid flows back into the interior of the treatment tank 1. Since the top of the one-way door 89 is rotatably mounted inside the air flow tube 84, when the one-way door 89 is no longer subjected to the thrust, 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 tube 84, and the bottom end of the one-way door 89 is inclined. When there is negative pressure inside the air flow tube 84, the inclined side wall of the bottom end of the one-way door 89 will prevent the one-way door 89 from rotating toward the inside of the air flow tube 84, ensuring that the inside of the air flow tube 84 is in a sealed state, making it convenient to suck the concentrated liquid in the filter cloth 55 into the interior of the air flow tube 84;

[0100] The guide frame 87 is fixedly mounted on the inner wall of the airflow tube 84, and the airflow tube 84 is in the shape of a prism;

[0101] The air flow tube 84 reduces the communicating area between the bottom and top ends of the air flow tube 84 , thereby preventing the concentrated liquid from flowing back into the installation frame 51 during the process of the piston plate 2 85 pushing the concentrated liquid into the reflux tube 88 .

[0102] The specific working method is as follows: by opening the sealing cover 22, the concentrated liquid to be processed is poured into the interior of the feeding tank 21, and the concentrated liquid flows into the interior of the processing tank 1 along the inner wall of the feeding tank 21, and the impurities in the concentrated liquid are filtered through the filter screen 28 to ensure that the concentrated liquid is clean; through the mutual cooperation of the positioning slide 44 and the positioning slider 45, the positioning frame 26 can rotate synchronously with the drive shaft 24, because the push rod 41 is fixedly mounted on the top of the positioning frame 25, and the side wall of the guide block 42 is inclined, when the positioning frame 26 rotates, the push rod 41 can push the positioning frame 26 to move upward, shortening the distance between the partition cover 35 and the filter screen 28, and the partition cover 35 is kept in a fixed 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 therefore squeezed, thereby 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 squeezed by the partition cover 35, and the residual concentrated liquid therein can be effectively squeezed out, thereby avoiding the waste of concentrated liquid. By locating the part of the filter cloth 55 that passes through the processing tank 1 at the bottom of the winding drum 54, when the winding drum 54 rolls up the filter cloth 55, the impurities on the surface of the filter cloth 55 can be wrapped up, which is convenient for collecting impurities. At the same time, the filter cloth 55 will be squeezed when it is rolled up, and the concentrated liquid accumulated on the filter cloth 55 is therefore squeezed out and refluxed to the interior of the processing tank 1 through the reflux frame 56, further avoiding the waste of concentrated liquid. Waste, when the driving shaft 24 drives the positioning frame 26 to rotate, the guide block 42 will contact the side wall of the sliding rod 66, pushing the sliding rod 66 to move downward, and the linkage block 67 will therefore push the extrusion block 64 and the piston plate 1 62 to move toward the inside of the gas storage frame 61, and the air inside the processing tank 1 will be sucked into the inside of the gas storage frame 61. The internal top of the processing tank 1 is sealed by the partition cover 35, so the internal bottom end of the processing tank 1 generates a negative pressure, so that the concentrated liquid on the surface of the filter cloth 55 is accelerated to pass through the filter cloth 55 under the action of the pressure difference, and the impurities in the concentrated liquid are trapped on the surface of the filter cloth 55, thereby increasing the filtration speed of the filter cloth 55. When the movement of the piston plate 1 62 drives the extended end of the hydraulic rod 81 to extend, the extended end of the mounting bracket 83 on the mounting bracket 83 contracts, and the piston plate 2 85 is compressed. This movement creates negative pressure inside the mounting frame 51 and the airflow tube 84, and the concentrated liquid on the filter cloth 55 is therefore sucked into the airflow tube 84 through the connecting hole 86, further processing the concentrated liquid remaining on the filter cloth 55 to avoid waste of the concentrated liquid. When the movement of the piston plate 1 62 drives the extended end of the hydraulic rod 81 to retract, the extended end of the mounting bracket 83 on the mounting bracket 83 extends, and the piston plate 2 85 therefore pushes the concentrated liquid inside the airflow tube 84 to move inside the return pipe 88, causing the concentrated liquid to flow back into the processing tank 1. Since the top end of the one-way door 89 is rotatably mounted inside the airflow tube 84, when the one-way door 89 is no longer subjected to thrust, the one-way door 89 rotates downward due to the influence of gravity to seal the connection between the return pipe 88 and the airflow tube 84.The bottom end of the one-way door 89 is inclined. When negative pressure is generated inside the airflow tube 84, the inclined sidewall at the bottom end of the one-way door 89 prevents the one-way door 89 from rotating toward the inside of the airflow tube 84, thereby ensuring that the inside of the airflow tube 84 is sealed. This facilitates the suction of the concentrated liquid inside the filter cloth 55 into the airflow tube 84, and the discharge of the concentrated liquid after the impurities are filtered out through the discharge pipe 9.
