Description

Technical Field

[0001] The invention relates to the field of preparation of medical preparations, and in particular to a device for preparing a nose protection composition. Background Art

[0002] Existing medical, dental or cosmetic preparations often need to extract effective groups from plants. For example, natural ingredients are extracted from Xanthium sibiricum to prepare nasal protection compositions. Xanthium sibiricum is an annual herb of the genus Xanthium in the Asteraceae family. Xanthium sibiricum is bitter, pungent and cold in nature. It can dispel wind and heat, detoxify and kill insects. It is mainly used to treat headaches, dizziness and vertigo. It has pharmacological effects on lowering blood sugar, respiratory system, cardiovascular system and anti-inflammatory effects, and can be used to treat rhinitis.

[0003] In the related art, the production process of Xanthium sibiricum extract is to crush the Xanthium sibiricum, decoct it in sesame oil with other auxiliary medicinal materials for a period of time, and then filter the medicinal materials. The retained sesame oil contains the effective components of Xanthium sibiricum. Although the above method can extract the effective components of Xanthium sibiricum, it is mostly manual operation, with complicated steps and low preparation efficiency. For example, the Chinese patent document with application publication number CN 103040890 A discloses a method for enriching and purifying total saponins of Xanthium sibiricum, in which the raw materials are coarsely crushed and then put into the feeding hopper, the main machine of the extraction tank group rotates, and the materials are slowly pushed backward from the front end of the unit, and the extraction solvent enters the extraction tank from the liquid inlet pipe at the end of the unit, and flows from the rear end of the tank through the moving material to the front end, and the solid-liquid two-phase substances are fully contacted in this reverse motion, so as to extract the effective components in the medicinal materials, and the dregs are forced to be pushed to the slag outlet by the discharging conveyor and discharged, and a special juicer squeezes the dregs, squeezes the residual liquid from the dregs out of the medicinal material tissue, and reduces the residual liquid content of the dregs. Although this method has achieved a certain degree of automation, the work is not continuous enough during the extraction process, resulting in low work efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, a nasal protection composition preparation device provided by an embodiment of the present invention includes an extraction cylinder 110, a liquid feeding mechanism and a material feeding mechanism; an extraction chamber is formed inside the extraction cylinder 110, and a feed port, a discharge port 1151, an oil inlet and an oil outlet connected to the extraction chamber are provided on the extraction cylinder 110, and the oil inlet and the oil outlet are located between the feed port and the discharge port 1151, and the oil inlet is located above the oil outlet.

[0022] The liquid delivery mechanism includes an oil inlet pipeline 217, an oil outlet pipeline 213 and a circulation body which are connected to each other. The circulation body is connected to the oil inlet and the oil outlet. The circulation body is used to transport the extract to the inside of the extraction chamber and make the extract circulate. The oil inlet pipeline 217 is used to pass the external extract into the circulation body. The oil outlet pipeline 213 is used to discharge the extract with qualified concentration. A first switch valve 2131 is arranged on the oil outlet pipeline 213, and a second switch valve 2171 is arranged on the oil inlet pipeline 217. The oil flow rate of the first switch valve 2131 and the second switch valve 2171 can be adjusted.

[0023] The feeding mechanism is used to feed the material from the feed port into the extraction chamber and push the material from top to bottom. During the material operation, the material contacts the extraction liquid in the extraction chamber. When it runs to the bottom, the extraction liquid is discharged from the oil outlet to the liquid feeding mechanism, and the residue is discharged from the outlet 1151.

[0024] It should be explained that, during operation, the material continuously enters the extraction cylinder 110 from the feed port and continuously moves downward under the action of the feeding mechanism. The liquid feeding mechanism feeds a certain amount of extraction liquid into the extraction chamber inside the extraction cylinder 110 and contacts with the material. At the same time, under the action of the liquid feeding mechanism, the extraction liquid circulates. After the concentration of the extraction liquid reaches the requirement, part of the qualified extraction liquid is released from the oil outlet pipe 213, and at the same time, new extraction liquid is added from the oil inlet pipe 217 to continue to participate in the circulation, thereby realizing continuous and uninterrupted extraction of the material with high extraction efficiency.

[0025] In a further embodiment, the circulation body includes an outer cylinder 210, an inner cylinder 209, an oil return pipeline 219 and an oil delivery pipeline 205; the outer cylinder 210 is connected to the oil outlet.

[0026] The inner cylinder 209 is coaxially arranged inside the outer cylinder 210 with a gap between the inner cylinder 209 and the outer cylinder 210. A piston 211 is arranged inside the inner cylinder 209. The piston 211 can reciprocate along the axis of the inner cylinder 209. The piston 211 divides the inner cylinder 209 into an upper space and a lower space. The lower space of the inner cylinder 209 is connected to the outer cylinder 210. Specifically, the bottom of the inner cylinder 209 is open and further connected to the inner cylinder 209.

[0027] One end of the return oil pipeline 219 is arranged at the bottom of the outer cylinder 210 and connected to the interior of the outer cylinder 210, and the other end is arranged at the top of the inner cylinder 209 and connected to the upper space of the inner cylinder 209. A third switch valve 2191 is arranged on the return oil pipeline 219, and the third switch valve 2191 is used to control the on and off of the return oil pipeline 219.

[0028] The oil delivery pipeline 205 is spiraled around the peripheral wall of the extraction cylinder 110, the lower end of the oil delivery pipeline 205 is connected to the upper space of the inner cylinder 209 through the connecting pipeline 207, and the upper end of the oil delivery pipeline 205 is connected to the oil inlet. The oil inlet pipeline 217 is connected to the upper space of the inner cylinder 209, and the oil outlet pipeline 213 is set at the lower end of the outer cylinder 210 and connected to the outer cylinder 210.

[0029] Furthermore, the circulation body also includes a driving member, which is used to drive the piston 211 to reciprocate along the axis of the inner cylinder 209. In a preferred embodiment of the present invention, the driving member is a hydraulic cylinder 212. In other embodiments, the driving member can also be a pneumatic cylinder, an electric cylinder, or other power element that can achieve the same function.

[0030] At the beginning of the operation, first close the third switch valve 2191 and the first switch valve 2131, open the second switch valve 2171, and feed the extract into the upper space of the inner cylinder 209 through the oil inlet pipe 217. During the upward movement of the piston 211, the extract is fed into the extraction cylinder 110. After a certain amount of extract is introduced, close the second switch valve 2171, open the third switch valve 2191, and reciprocate the piston 211 to allow the extract to circulate through the return oil pipe 219. After the concentration of the extract meets the requirements, open the first switch valve 2131 and the second switch valve 2171. Each time the piston 211 moves downward, a certain amount of qualified extract is discharged through the oil outlet pipe 213, and a certain amount of new extract is added through the oil inlet pipe 217. Each time the piston 211 moves upward, the extract is pumped into the extraction cylinder 110 through the upper space of the inner cylinder 209, so that the effective substances of the material can be continuously and efficiently extracted. It should be noted that, referring to Figure 7 One-way valves 208 are provided on the oil outlet pipeline 213, the connecting pipeline 207, the oil return pipeline 219 and the oil inlet pipeline 217 to achieve directional circulation of the extract.

The main feeding blade 120 is fixedly arranged on the outer peripheral wall of the rotating shaft 121 and is located inside the extraction chamber. The main feeding blade 120 is a spiral blade and its pitch gradually decreases from top to bottom. During the rotation of the main feeding blade 120, the material is pushed from top to bottom. Since the pitch of the main feeding blade 120 decreases, the material is subjected to greater extrusion force as it moves downward. The extract in the material is squeezed out and discharged from the oil outlet to the outer cylinder 210, and the residue is discharged from the outlet 1151. By specially setting the pitch of the main feeding blade 120, the main feeding blade 120 can not only complete the feeding, but also complete the extrusion of the material, without the need to set up a separate extrusion device, so as to achieve continuous extraction of the material.

[0034] In a further embodiment, a laminate 117 is provided at the oil outlet of the extraction cylinder 110 , so as to filter the extraction liquid flowing from the extraction chamber to the outer cylinder 210 .

[0038] For ease of structural setting, refer to Figure 4 and Figure 8 The extraction cylinder 110 includes a main cylinder 111, a limiting ring 112, a supporting cylinder 113 and a protective cylinder 114; the main cylinder 111, the limiting ring 112 and the supporting cylinder 113 are arranged in sequence from top to bottom, a discharge tray 115 is arranged between the supporting cylinder 113 and the limiting ring 112, an extraction chamber is located above the discharge tray 115, and a discharge chamber is located below the discharge tray 115, that is, the main cylinder 111, the limiting ring 112 and the discharge tray 115 form an extraction chamber, the supporting cylinder 113 and the discharge tray 115 form a discharge chamber, the protective cylinder 114 is arranged on the outside of the limiting ring 112, and a transition chamber is formed between the protective cylinder 114 and the limiting ring 112.

[0039] The oil outlet is opened on the side wall of the limiting ring 112. There are multiple oil outlets and they are evenly distributed along the circumferential direction of the limiting ring 112. The stack 117 is sleeved on the outside of the limiting ring 112 and is located in the transition chamber. The side wall of the protective tube 114 is provided with a connecting port 1141 for connecting with the outer tube 210 of the liquid feeding mechanism. The material is pushed and squeezed by the main feeding blades 120, and the extract in the material is discharged to the transition chamber through the oil outlet hole. During the discharge process, it is filtered by the stack 117 and then flows back to the inner tube 209 from the transition chamber through the connecting port 1141.

[0040] The discharge port 1151 is arranged on the peripheral wall of the discharge tray 115, that is, the discharge port 1151 is located below the oil outlet and the discharge port 1151 is connected to the extraction chamber and the discharge chamber, the guide plate 116 is arranged inside the supporting cylinder 113, the slag discharge port 1132 is arranged on the side wall of the supporting cylinder 113, and a supporting cover plate 1152 is arranged at the bottom of the discharge tray 115 for supporting the rotating shaft 121.

[0041] A top cover 1111 is provided on the top of the main cylinder body 111 . The top cover 1111 is detachable, a feed port is arranged at the center of the top cover 1111 , and the auger cylinder 125 and the support frame 1112 are both arranged on the top cover 1111 .

[0042] At the beginning of the operation, the second switch valve 2171 is opened, the first switch valve 2131 and the third switch valve 2191 are closed, the extraction liquid is introduced from the oil inlet pipeline 217, and the hydraulic cylinder 212 is started to move the piston 211 up and down. When the piston 211 moves downward, the extraction liquid is sucked into the upper space of the inner cylinder 209 from the oil inlet pipeline 217, and the inner cylinder 209 discharges gas into the extraction chamber. Then the piston 211 moves upward, and the extraction liquid in the upper space of the inner cylinder 209 is discharged from the connecting pipe into the oil delivery pipeline 205, and is discharged from the oil outlet ring 118 and falls into the extraction chamber.

[0043] When the amount of the introduced extracting liquid reaches a certain amount, the second switch valve 2171 is closed and the third switch valve 2191 is opened; the hydraulic cylinder 212 continues to work, and when the piston 211 moves downward, the extracting liquid moves from the outer cylinder 210 to the upper space of the inner cylinder 209 through the return oil pipeline 219; when the piston 211 moves upward, the extracting liquid is discharged from the upper space of the inner cylinder 209 through the oil pipeline 205 and the oil outlet ring 118 to the extraction cylinder 110, so that the extracting liquid circulates in the extraction chamber.

Alternatively, high-temperature heating liquid can be directly and continuously introduced into the heating chamber 133 from the heating liquid inlet 131, and the cooled heating liquid can be discharged from the heating liquid outlet 132. The heating liquid heats the extraction liquid in the oil pipeline 205, and at the same time heats and keeps the extraction cylinder 110 warm.

[0045] Afterwards, the motor 123 is started, and materials (such as crushed Xanthium sibiricum raw materials) are fed from the feeding hopper 126 to extract the essential oil; the auxiliary feeding blades 122 push the materials downward, and the thread lead angle of the auxiliary feeding blades 122 is small, which can make the sealing effect at the auger barrel 125 better and avoid pressure leakage; the materials fall into the extraction barrel 110 and are pushed downward by the main feeding blades 120. During this process, the extracting liquid contacts the materials at a faster speed and circulates continuously to continuously extract the effective substances in the materials.

[0046] The thread lead angle of the main feeding blade 120 decreases as it goes downward, squeezing the extracted material and the extract at the bottom. The extract is discharged from the stack 117 and enters the outer cylinder 210 , and the material residue is discharged from the discharge tray 115 .

[0047] After a period of extraction, when the concentration of the extract reaches the required concentration, the second switch valve 2171 and the first switch valve 2131 are opened, so that when the piston 211 is pressed down, a small part of the extract is discharged from the oil outlet pipe 213, and another large part of the extract enters the upper space of the inner cylinder 209 from the return oil pipe 219, and at the same time, a part of the new extract is replenished from the oil inlet pipe 217 and mixed with the original extract; the opening size of the second switch valve 2171 and the first switch valve 2131 can be freely adjusted according to the content of effective substances in Xanthium sibiricum; when the content of effective substances in Xanthium sibiricum is relatively high, the opening size of the first switch valve 2131 and the second switch valve 2171 can be increased to increase the working efficiency.

[0048] Finally, it is only necessary to feed materials from the feeding hopper 126 and add new extraction liquid from the oil inlet pipeline 217 to continuously extract the effective substances in the materials.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
