Description

Chinese Herbal Medicine Concentration Device

TECHNICAL FIELD The invention relates to the technical field of Chinese herbal medicine processing, in particular to a Chinese herbal medicine concentration device.

BACKGROUND Chinese Medica therapeutics adopts Chinese traditional medicine: Chinese traditional medicine is mainly composed of plant medicine (roots, stems, leaves and fruits), animal medicine (viscera, skin, bones, organs, etc.) and mineral medicine. Because herbal plant accounts for the majority of Chinese medicine, Chinese medicine is also called Chinese herbal medicine. Because of the uniqueness of TCM theory, patients can apply TCM to treat diseases, which can effectively avoid the drug resistance of western medicine. And because China is the birthplace of Chinese herbal medicine, there are about 12,000 kinds of medicinal plants in China at present, which are not available in other countries, and we have a monopoly advantage in Chinese herbal medicine resources.

Concentrated traditional Chinese medicine refers to concentrated pills, which are pills made by concentrating and refining the active ingredients in raw materials or some raw materials (some weak and bulky medicinal materials in the prescription) with high-tech equipment to make fluid extract or extract, and mixing with other raw materials fine powder or suitable excipients in the prescription.

In the prior art, traditional Chinese medicine concentration equipment is generally used for concentration of traditional Chinese medicine, such as Chinese patent, the announcement number is CN 212941862 U, a traditional Chinese medicine concentrator, which comprises a concentration tank body structure, and the upper end of the concentration tank body structure is provided with an upper cover structure; The upper end of the thickening tank body structure is also provided with a compression motor structure, the lower end of the compression motor structure is provided with a concentrated solution suction pipe structure, one side of the compression motor structure is provided with a water suction pump structure, one side of the water suction pump structure penetrating through the inside of the thickening tank body structure is provided with a water suction pipe structure, and the side away from the water suction pump structure is provided with a drain pipe structure, and the drain pipe structure is connected with a storage device; The lower end of the inner cavity of the thickening tank body structure is provided with a rotary motor structure, the upper end of the rotary motor structure is connected with a solution containing cavity structure, and the side walls of the solution containing cavity structure are all provided with stirring screw structures. The concentration equipment is convenient for cleaning, but the energy consumption of the concentration equipment is high and the concentration efficiency is low.

SUMMARY The invention aims to provide a Chinese herbal medicine concentration device to improve the concentration efficiency of Chinese herbal medicines. In order to achieve the above purpose, the invention adopts the following technical scheme: a Chinese herbal medicine concentration device comprises an inner cylinder with an upper opening and a cover plate for closing the opening; The cover plate is fixed with a reversing valve, a meter and a driver, one inlet end of the reversing valve is communicated with a feed pump, and the other inlet end of the reversing valve is communicated with a negative pressure pump; The cover plate is fixed with a plurality of support shafts uniformly distributed along its circumferential direction, and the support shafts are fixed with spirally uniformly distributed pipelines which are provided with a plurality of through holes and are communicated with the outlet end of the reversing valve; A support plate is fixed in the inner cylinder, a valve is fixed on the support plate, a hollow rotating shaft located in the inner cylinder is rotatably connected to the support plate, the upper end of the rotating shaft is detachably connected with the output shaft of the driver, the lower end of the rotating shaft is fixed with a power supply, a heater is fixed in the rotating shaft, the heater is electrically connected with the power supply, and a plurality of stirring blades located above the support plate are fixed at the lower part of the rotating shaft.

The principle and advantages of this scheme are as follows: (1) In this scheme, when the inner cylinder is vacuumized, the negative pressure pump is used to vacuumize and the meter is used to measure, so as to maintain the vacuum degree in the inner cylinder. After the vacuum pumping is completed, the reversing valve is used for reversing, and the medicine juice of Chinese herbal medicines is sent into the inner cylinder by the feed pump. When the medicine juice is sent into a certain amount, the negative pressure pump and the meter are used to maintain a certain vacuum degree, which is convenient for adjusting the vacuum degree of the inner cylinder.

(2) Start the power supply to supply power to the heater. The heater heats and concentrates the medicinal juice, and the generated water vapor is discharged by the negative pressure pump. In the process of discharging the water vapor, the negative pressure pump sucks the medicinal juice through the pipeline, and because there is a through hole in the pipeline, the medicinal juice falls back into the inner cylinder. In the process of falling back, the high temperature of the water vapor and the high temperature of the heater heat the medicinal juice, thereby increasing the heating of the medicinal juice and further improving the concentration efficiency of the medicinal juice.

(3) Inthe process of heating and concentrating the medicinal juice, the driver is started, and the driver drives the rotating shaft and the stirring blade to rotate, so as to stir the medicinal juice and further improve the concentration efficiency of the medicinal juice.

(4) After the concentration is completed, the concentrated medicinal juice is discharged through the valve, and when the cover body is removed, the supporting shaft and the pipeline are also removed, and the pipeline scrapes off the side wall of the inner cylinder to reduce the medicinal juice remaining on the inner wall of the inner cylinder, thus facilitating the cleaning of the inner cylinder. Preferably, as an improvement, a bearing sleeved on the output shaft of the driver is fixed on the cover plate. The bearing has the advantages that the friction between the output shaft of the driver and the cover plate is reduced.

Preferably, as an improvement, an outer cylinder is sleeved outside the inner cylinder, the lower part of the outer cylinder is provided with an air inlet pipe communicated with the negative pressure pump, and the upper part of the outer cylinder is communicated with an air outlet pipe.

Beneficial effects: the negative pressure pump sends water vapor into the air inlet pipe, and then enters the outer cylinder from the air inlet pipe to keep the inner cylinder warm; because the air inlet pipe is located below the air outlet pipe, the flow time of water vapor is prolonged, and then the inner cylinder is fully kept warm.

Preferably, as an improvement, a shell for protecting the power supply is fixed on the support plate, and the shell is rotatably connected with the power supply. The utility model has the advantages that: the power supply is protected by the shell, so that the drug juice is prevented from adhering to the power supply; and meanwhile, the shell is rotationally connected with the power supply, so that the rotation of the power supply cannot be hindered.

Preferably, as an improvement, an auxiliary cylinder is fixed on the support plate, the upper part of the auxiliary cylinder is tapered, the lower part of the auxiliary cylinder is vertically connected with an extrusion plate in a sliding way, the lower part of the extrusion plate is fixed with an extrusion shaft, and the power supply is fixed with a push shaft which is against the extrusion shaft.

Beneficial effects: the medicinal juice will enter the auxiliary cylinder and be supported by the extrusion plate. When the power supply rotates with the rotating shaft, the push shaft will push the extrusion shaft and the extrusion plate to slide upwards, and the medicinal juice will be accelerated through the upper part of the auxiliary cylinder, so that the medicinal juice can quickly enter the inner cylinder and roll over in the inner cylinder, thereby increasing the heated area of the medicinal juice and improving the concentration efficiency of the medicinal juice.

Preferably, as an improvement, a stop block fixed on the auxiliary cylinder is arranged below the extrusion plate.

Beneficial effects: the limiting block limits the extrusion plate. Preferably, as an improvement, the lower part of the inner cylinder is tapered.

Beneficial effects: when the valve is opened to discharge the medicinal juice, it enters the lower part of the inner cylinder, and the lower part of the inner cylinder is tapered, so that the medicinal juice can be quickly discharged.

Preferably, as an improvement, a filter screen above the air inlet pipe is fixed in the outer cylinder.

Beneficial effects: The water vapor contains certain particles, and the particles are filtered through the filter screen, so that the particles are prevented from being discharged into the air when the water vapor is discharged.

Example 1 Basically, as shown in Fig. 1 to Fig. 3, a Chinese herbal medicine concentration device comprises a frame, on which a circular inner cylinder 12 is bolted, an opening is formed in the upper part of the inner cylinder 12, and a cover plate 13 for closing the opening is arranged above the inner cylinder 12.

A reversing valve 15 is bolted to the cover plate 13, and an inlet end of the reversing valve 15 is communicated with a feed pipe 17, and the feed pipe 17 is communicated with a feed pump (not shown in the figure); the other inlet end of the reversing valve 15 is connected with a negative pressure pump 18. The cover plate 13 is bolted with a gauge. In this embodiment, the gauge is a digital display vacuum gauge 18, which is used to detect the vacuum degree in the inner cylinder 12. The cover plate 13 is bolted with several supporting shafts 21, which are evenly distributed along the circumferential direction of the cover plate 13. The cover plate 13 is provided with pipes 22, one end of which is communicated with the outlet end of the reversing 5 valve 15, and the other end of which is communicated with the inner cylinder 12. The pipes 22 are spirally evenly distributed and fixed on the supporting shafts 21. The pipes 22 are provided with several through holes, and the pipes 22 abut against the inner side wall of the inner cylinder 12.

The cover plate 13 is bolted with a driver. In this embodiment, the driver is a motor 14, and the output shaft of the motor 14 penetrates through the cover plate 13. The output shaft of the motor 14 is sleeved with a bearing 141 fixed on the cover plate 13, and the bearing 141 is a ball bearing 141.

The bottom of the inner cylinder 12 is tapered. The lower part of the inner cylinder 12 is bolted with a support plate 25, on which a valve 24 is bolted. The support plate 25 is rotatably connected with a rotating shaft 23 located in the inner cylinder 12. The rotating shaft 23 is hollow, and the lower part of the rotating shaft 23 is bolted with several stirring blades 29, which are located above the supporting plate 25. The bottom of the rotating shaft 23 is provided with a power supply 27, which includes a shell and a storage battery in the shell. A heater 28, which is a heating rod, is screwed in the rotating shaft 23 and electrically connected with the storage battery. A shell for protecting the power supply 27 is bolted to the support plate 25, and the shell is rotatably connected with the shell.

The upper frame bolt is fixed with an outer cylinder 11 which is sleeved outside the inner cylinder 12, the lower part of the outer cylinder 11 is fixed with an air inlet pipe, the upper part of the outer cylinder 11 is fixed with an air outlet pipe 111, and the air inlet pipe is communicated with the air outlet of the negative pressure pump 18.

The operation steps of this equipment are as follows.

Step 1: the operator adjusts the reversing valve 15, connects the negative pressure pump 18 with the pipeline 22, and vacuumizes the inner cylinder 12, and stops vacuumizing when a certain value is displayed on the meter.

Step 2: the operator adjusts the reversing valve 15 again, connects the feed pipe 17 with the pipe 22, and sends the medicinal juice into the inner cylinder 12. Then, the motor 14 and the heater 28 are started, and the heater 28 heats and concentrates the medicinal juice. The motor 14 drives the rotating shaft 23 and the stirring blades 29 to rotate, so as to stir the medicinal juice, increase the heated area of the medicinal juice and accelerate the concentration of the medicinal juice.

Step 3: because water vapor will be generated in the process of medicine juice concentration to change the vacuum condition of the inner cylinder 12, when the numerical value on the meter changes, the operator adjusts the reversing valve 15 to make the pipeline 22 communicate with the negative pressure pump 18, so as to pump the water vapor away, and of course, the medicine juice will also be pumped into the pipeline 22; However, because the pipe 22 is provided with a through hole, the medicinal juice will fall back into the inner cylinder 12, and the water vapor will be discharged. In the process of dropping the medicinal juice, the steam and heater 28 further heat the medicinal juice, thereby improving the concentration efficiency of the medicinal juice. The water vapor pumped by the negative pressure pump 18 enters the outer cylinder 11 to keep the inner cylinder 12 warm, and the beneficial air inlet pipe is located below the air outlet pipe 111, thus prolonging the flow time of the water vapor and fully keeping the medicine juice in the inner cylinder 12 warm.

Step 4: after concentration, the medicinal juice is discharged through the valve 24. Take off the cover plate 13. In the process of taking off the cover plate 13, the pipe 22 will scrape off the medicinal juice on the inner side wall of the inner cylinder 12 to reduce the residue of the medicinal juice in the inner cylinder 12.

Example 2: The difference between the second embodiment and the first embodiment lies in that, as shown in Fig. 4 and Fig. 5, several sub-cylinders 32 are fixed on the support plate 25, and the sub-cylinders 32 communicate with the inner cylinder 12. The upper part of the sub-cylinders 32 is tapered and has a smaller diameter than the lower part of the sub-cylinders 32. The lower part of the sub-cylinders 32 is vertically slidably connected with an extrusion plate 35, the bottom of the extrusion plate 35 is screwed with an extrusion shaft 34, and the lower part of the extrusion plate 35 is provided with a limiting block 36, and the limiting block 36 is screwed on. The screw on the power supply 27 is fixed with a push shaft 33 (that is, the push shaft 33 is fixed on the shell), and the upper end of the push shaft 33 is matched with the lower end of the extrusion shaft 34.

A filter screen 31 is fixed in the outer cylinder 11 by screws, which is located above the air inlet pipe. The water vapor contains some particles. After entering the outer cylinder 11, the water vapor is filtered through the filter screen 31 to reduce the probability of particles being discharged into the air, so as to avoid air pollution caused by gas with particles.

The specific implementation process is as follows: After the medicinal juice is put into the inner cylinder 12, part of the medicinal juice will enter the auxiliary cylinder 32 and be supported on the extrusion plate 35. When the rotating shaft 23 rotates, the rotating shaft 23 will drive the shell and the pushing shaft 33 to rotate. When the pushing shaft 33 abuts against the squeezing shaft 34, the squeezing shaft 34 will push the squeezing plate 35 to slide upwards, so that the squeezing plate 35 will squeeze the medicinal juice into the inner cylinder 12. Because the upper part of the sub-cylinder 32 is tapered and its diameter is smaller than that of the lower part of the sub-cylinder 32, the medicinal juice will be discharged into the inner cylinder 12 at an accelerated speed, so that the medicinal juice will tumble and work back and forth, thus further rapidly concentrating the medicinal juice.

What has been described above is only an example of the present invention, and common knowledge such as specific technical schemes and/or characteristics that are well known in the schemes are not described too much here.

It should be pointed out that for those skilled in the field, without departing from the technical scheme of the present invention, several modifications and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.

The scope of protection required by this application shall be subject to the content of its claim, and the specific implementation and other records in the specification can be used to interpret the content of the claim.
