Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traditional Chinese medicine extraction, in particular to a steam condenser for traditional Chinese medicine extraction. BACKGROUND

[0002] In the extraction process of traditional Chinese medicine, concentrators and condensers are needed. The concentrator evaporates the water in the medicinal liquid by heating to extract medicinal liquid with higher concentration. The condenser cools the high-temperature steam discharged from the concentrator, so that the medicinal liquid components contained in the high-temperature steam can flow back to the concentration tank for further extraction.

[0003] For example, the patent number CN210874185U discloses a traditional Chinese medicine steam condenser. Its main structure includes a condensing sleeve, a drainage opening is provided on the outer wall of the condensing sleeve, a sealing cover is threadedly connected to one end of the condensing sleeve, a sealing plate is embedded on one side of the sealing cover, a first sealing ring is embedded between the sealing plate and the condensing sleeve, a connecting pipe is penetratingly provided on one end of the inner wall of the condensing sleeve and one side of the sealing plate, a condensing branch pipe is inserted between the corresponding connecting pipes, a water inlet groove is fixedly provided on the other side of the sealing plate, a water inlet is fixedly connected to one side of the water inlet groove, an air inlet is penetratingly provided on one end of the inner wall of the condensing sleeve, and an air outlet is penetratingly provided on the other end of the condensing sleeve. In use, the condensing sleeve is arranged as a hollow U-shaped pipe, and a plurality of condensing branch pipes are arranged in the condensing pipe, so that the water in the hollow part of the condensing sleeve and the condensing branch pipes can fully transfer heat with the medicinal liquid steam flowing into the inner wall of the condensing sleeve, thereby improving the condensing efficiency.

[0004] From the above description, it can be seen that the device can only be used for condensing high-temperature steam in the concentrator under normal atmospheric pressure. In order to improve the efficiency and condensing effect of the existing concentrator, the inside of the condensing cavity is in a vacuum or negative pressure state during heating, which causes the internal pressure of the concentrator to be much lower than the external atmospheric pressure. Once the air inlet of the traditional Chinese medicine steam condenser is connected to the exhaust port of the concentrator, the low-pressure area will cause the internal high-temperature steam to be unable to move, and the high-temperature steam will not flow according to the predetermined route, resulting in failure to work.

In order to pre-store the condensed liquid in the condensing cavity 3, the horizontal height of the liquid discharge port 14 needs to be lower than that of the gas discharge port 15. The condensed liquid is gathered in the condensing cavity 3. Once the liquid volume reaches the position of the gas discharge port 15, the liquid is discharged outward through the gas discharge port 15. When the staff observes the liquid outflow, it indicates that the collection amount of the liquid has reached the maximum degree that needs to be reflowed to the concentration tank for further concentration, thereby playing a warning role.

[0030] In order to realize the condensing effect of the flowing high-temperature steam, please refer to Figure 1 and Figure 2, need to set the spiral water cooling structure 11, located in the condensation cavity 3 inside, and both ends through the corresponding structure of vertical tank 1, the inside of the spiral water cooling structure 11 is provided with the liquid circulation flow hole 114 for circulating flow of condensed water, after the liquid in the liquid circulation flow hole 114 inside flow, and in the liquid refrigeration effect, will be cooled in its surrounding flow of high temperature steam cooling effect, due to the high temperature steam temperature decreases, will gather into liquid state, finally under the action of gravity can fall in the bottom area of condensation cavity 3, so as to realize the condensation effect of high temperature steam, so that the high temperature steam reaggregation into liquid, and the liquid due to containing some drug ingredients, therefore, can cause concentration, improve the effective utilization rate of traditional Chinese medicine.

[0031] Regarding the specific structure of the spiral water cooling structure 11, please refer to Figure 3 , including the spiral pipe body 111 inside the condensation cavity 3, in order to have excellent heat transfer effect, preferably the spiral pipe body 111 is made of spiral structure of excellent thermal conductivity material, the top and bottom ports of the spiral pipe body 111 are provided with the first and second horizontal pipe body 112 and 113 of one-piece structure and through the corresponding structure of vertical tank 1, the center of the spiral pipe body 111, the first and second horizontal pipe body 112 and 113 are provided with the liquid circulation flow hole 114 for circulating flow of condensed water, the first and second horizontal pipe body 112 and 113 are connected with the circulation port of a liquid cooler, when the liquid cooler works, the liquid in the low temperature state can flow inside the liquid circulation flow hole 114, and the heat in the high temperature steam will be transferred to the spiral pipe body 111, and finally to the low temperature liquid, in the exchange of heat, the temperature of the high temperature steam decreases, and the steam will recondense into liquid state.

[0032] In order to realize the directional flow control of high temperature steam, please refer to Figure 1 , need to set the steam flow cavity 4, set in the top of high temperature steam discharge port 8, and the side bottom is provided with high temperature steam inlet 7 for high temperature steam into its inside, the inside of high temperature steam inlet 7 is installed with the first gas-liquid one-way valve 9 which can control the one-way flow of high temperature steam into the steam flow cavity 4, the inside of high temperature steam discharge port 8 is installed with the second gas-liquid one-way valve 10 which can control the one-way flow of high temperature steam into the condensation cavity 3, when the high temperature steam is discharged from the condenser tank and enters the steam flow cavity 4 through the high temperature steam inlet 7, due to the action of the first gas-liquid one-way valve 9, the steam will not flow back to the inside of the high temperature steam inlet 7, and finally can be discharged to the inside of the condensation cavity 3 through the high temperature steam discharge port 8, so as to realize the one-way movement of high temperature steam, prevent the backflow of steam from causing the phenomenon of not working.

[0033] In order to realize the function of inhaling and directional discharging of high temperature steam, please refer to Figure 1 , it is necessary to set a rotary linear motion structure 12, which is installed in the fixed shell 5 and the inside of the steam flow cavity 4, and is internally provided with a reciprocating sliding groove 124 rotating with the driving motor 6, a sliding rod 126 sliding along the reciprocating sliding groove 124 in a fixed direction and generating up and down reciprocating motion state, and an elastic air film 128 which can inhale high temperature steam from the high temperature steam inlet 7 and discharge it to the high temperature steam discharge port 8 when the sliding rod 126 moves. When the sliding rod 126 slides along the rotating reciprocating sliding groove 124, the elastic air film 128 will deform. When the elastic air film 128 is pulled up, the high temperature steam can be adsorbed into the area below the elastic air film 128. When the elastic air film 128 contracts, the high temperature steam below it will be pressed into the condensation cavity 3, thereby realizing the function of inhaling and directional discharging of high temperature steam. Since the elastic air film 128 itself has buffering and deformation ability, it can form a buffer driving effect for the low pressure inhalation and high pressure discharge of high temperature steam during deformation, thereby improving the stability of the component during work.

[0034] For the specific structure of the rotary linear motion structure 12, please refer to Figure 4 and Figure 5, including the hollow column 121 installed inside the fixed shell 5 and the hexagonal rod 125 penetrating through the top center structure of the vertical tank body 1, in order to enable the hexagonal rod 125 to produce a longitudinal movement effect but not a rotating movement, thereby offsetting the torque force when rotating, it is necessary to make the cross-sectional structural outline of the hexagonal rod 125 consistent with the cross-sectional structural outline of the through hole of the vertical tank body 1 at the penetrated part, both being hexagonal structures and matching in size in cross section, the top center of the hollow column 121 is provided with a shaft body installation groove 122 for fixing and installing the rotor structure of the driving motor 6, the bottom center of the hollow column 121 is provided with a component insertion groove 123, the hollow column 121 is provided with a reciprocating sliding groove 124 along the inner wall of the component insertion groove 123, in order to enable stable and relatively smooth up and down driving ability during rotation, it is necessary to make the projection of the reciprocating sliding groove 124 in the horizontal plane and the vertical plane both O-shaped structures, the top end of the hexagonal rod 125 is located inside the component insertion groove 123 and is provided on one side with a sliding rod 126 that can be inserted horizontally into the inside of the component insertion groove 123, the bottom end of the hexagonal rod 125 is located inside the steam flow cavity 4 and is installed with an annular embedded block 127, the annular elastic air film 128 is embedded in the annular groove of the annular embedded block 127, in order to enable the elastic air film 128 to have sufficient extrusion ability, thereby maximizing the high-pressure steam generation driving ability located below it, it is necessary to make the deformation resistance strength of the elastic air film 128 sufficient to enable high-pressure steam to be sucked out of the condensation tank in the working state, the circumferential surface of the elastic air film 128 is embedded in the inner wall of the steam flow cavity 4 and the embedded height is located above the high-temperature steam inlet 7, when the reciprocating sliding groove 124 rotates with the driving motor 6, since the hexagonal rod 125 cannot rotate and the contact height of the reciprocating sliding groove 124 and the sliding rod 126 constantly changes, when the contact height of the reciprocating sliding groove 124 and the sliding rod 126 increases, the elastic air film 128 will pull upwards, at this time, the high-pressure steam in the condensation tank will be sucked into the inside of the steam flow cavity 4, thereby enabling the high-temperature steam generated in the condensation tank to be sucked in time, and by controlling the rotation speed of the driving motor 6, the speed of the high-temperature steam being sucked in can be controlled, the amount of steam being sucked in can be controlled to basically match the amount of high-temperature steam generated in the condensation tank, which can not only ensure that the high-temperature steam is sucked in time and condensed, thereby improving the efficiency during condensation, but also ensure that the low-pressure state in the condensation tank remains basically consistent, thereby reducing the negative impact on the low-pressure state in the condensation tank.

[0035] In order to enable the condensed traditional Chinese medicine liquid to be discharged into the condensation tank for condensation treatment after reaching the rated pressure, please refer to Figure 1, need to set up the elastic resistance pressure relief structure 13, fixedly installed in the liquid discharge port 14 discharge port, and internally provided with the elastic strength and the concentration tank in the work of low pressure strength is basically the same spiral spring 135 and the valve plate 136 squeezed by the spiral spring 135 and in the closed state, when need to make the condensed after the traditional Chinese medicine liquid is discharged again to the concentration tank in the concentration treatment, can improve the speed of the driving motor 6, due to the increase of the elastic gas film 128 movement speed, will make the high pressure steam and concentration tank in the suction speed increases, resulting in the pressure in the concentration tank decreases, at this time, the ultra low pressure state in the concentration tank will act on the bottom end surface of the valve plate 136, when the ultra low pressure intensity is greater than the elastic strength of the spiral spring 135, will make the valve plate 136 downward movement, so that the liquid can be sucked into the concentration tank through the valve plate 136 and the top end gap of the component movable cavity 134 and the liquid flow gap 137, so that the condensed after the traditional Chinese medicine liquid is discharged again to the concentration tank.

[0036] Regarding the specific structure of the elastic resistance pressure relief structure 13, please refer to Figure 6 And Figure 7 , including cylindrical hollow shell 131, the center of the cylindrical hollow shell 131 is provided with the component movable cavity 134, the top end of the cylindrical hollow shell 131 is provided with the top liquid flow port 132 which is fixedly installed in the liquid discharge port 14 discharge port and can make the liquid enter into the inside of the component movable cavity 134, the bottom end of the cylindrical hollow shell 131 is provided with the bottom liquid flow port 133 which can make the liquid discharge outward from the component movable cavity 134, the inside of the component movable cavity 134 is placed with the valve plate 136 which can resist in the bottom end of the top liquid flow port 132 and can block the bottom port of the top liquid flow port 132, the circumferential surface of the valve plate 136 is provided with a plurality of liquid flow gaps 137 which are recessed to the center and used for liquid flow, the bottom end of the valve plate 136 is placed with the spiral spring 135 in the compressed state, because the elastic strength of the spiral spring 135 in the initial state is basically the same as the low pressure strength in the work of the concentration tank, therefore, when the liquid discharge work is not needed, the spiral spring 135 can make the valve plate 136 block the discharge port of the top liquid flow port 132, so as not to have negative impact on the low pressure state in the concentration tank.

[0037] In use, the high-temperature steam is introduced into the steam inlet 7 through the high-pressure pipeline, and the steam outlet of the traditional Chinese medicine extraction vacuum or low-pressure concentration tank, the bottom liquid flow port 133 is connected with the liquid injection port of the concentration tank, and the first and second horizontal pipeline bodies 112 and 113 are connected with the circulation port of a liquid refrigerator. Then, the liquid refrigerator and the driving motor 6 are started. At this time, the rotation speed of the driving motor 6 is controlled to control the speed of the high-temperature steam being sucked, so that the amount of the steam being sucked is basically consistent with the amount of the high-temperature steam generated in the concentration tank. During operation, the condensed gas can be discharged through the gas discharge port 15. When liquid is discharged through the gas discharge port 15, the rotation speed of the driving motor 6 is increased. Due to the increase of the movement speed of the elastic air film 128, the suction speed of the high-pressure steam in the concentration tank is increased, which leads to the decrease of the pressure in the concentration tank. At this time, the ultra-low pressure state in the concentration tank acts on the bottom end face of the valve plate 136. When the intensity of the ultra-low pressure is greater than the elastic intensity of the spiral spring 135, the valve plate 136 moves downward, so that the liquid can be sucked into the concentration tank through the gap between the top end of the component movable cavity 134 and the valve plate 136 and the liquid flow gap 137, so that the condensed traditional Chinese medicine liquid is discharged into the concentration tank again for cyclic concentration.

[0038] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
