Description

Technical Field

[0001] The invention relates to the technical field of Chinese patent medicine production, in particular to a concentrating device for Chinese patent medicine production. Background Art

[0002] Chinese patent medicines are made from Chinese medicinal materials. Under the guidance of traditional Chinese medicine theory, in order to prevent and treat diseases, they are processed into Chinese medicine products of a certain dosage form according to the prescribed prescriptions and preparation processes. The production of Chinese patent medicines involves multiple links, including raw material procurement, processing and extraction, concentration, quality control and packaging. In this process, the concentration process of Chinese medicine extracts consumes the most energy. At present, the concentration of Chinese patent medicines is generally achieved through three methods: MVR concentrators, double-effect external circulation forced concentrators and pure electric circulation concentrators. Among them, the pure electric circulation concentrator is based on the principle of heat pumps and the working principle of the classic double-effect concentrator, which can save the most concentration costs.

[0003] During the use of the pure electric circulation concentrator, when the condensed heat source heats the concentrator, minerals or scale are likely to remain on the surface of the container that has been in contact with the heat source for a long time, which can easily affect the subsequent heating effect, reduce production efficiency, and be inconvenient to clean, which is time-consuming and labor-intensive. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a concentration device for the production of Chinese patent medicines, which solves the problem that minerals or scale are easily left on the surface of containers that are in contact with the heat source for a long time, which easily affects the subsequent heating effect, reduces production efficiency, is inconvenient to clean, and is time-consuming and labor-intensive.

[0032] Two screw mechanisms are respectively arranged on the sides of the first effect concentrator 4 and the second effect concentrator 5, and are used to drive the cleaning assembly 7 to move up and down. The screw mechanism includes a fixed plate 8 arranged on the sides of the two concentrators, a first motor 9 is fixedly connected to the bottom of the inner side of the fixed plate 8, and a screw 10 is fixedly connected to the output end of the first motor 9, a slide plate 11 is slidably arranged on the inner side of the fixed plate 8, and a vertical rod 12 is fixedly connected to the bottom of the slide plate 11, and the bottom end of the vertical rod 12 is fixedly connected to the top of the annular plate 71;

[0033] The first-effect concentrator 4 and the second-effect concentrator 5 both include an outer cylinder 13 and an inner cylinder 14 fixed inside the outer cylinder 13 , a heating chamber 15 is provided between the outer cylinder 13 and the inner cylinder 14 , and an annular groove 16 adapted to the sealing plate 6 is provided on the top of the outer cylinder 13 .

[0034] Through the arrangement of the above structure, after opening the sealing plate 6, the screw mechanism can drive the nozzles 72 inside and outside the annular plate 71 to spray the cleaning agent evenly in the heating chamber 15 up and down. Then, after being stationary for a period of time, the screw mechanism drives the annular cleaning brush 75 to move up and down again, and cooperates with the external flushing system to brush the inner wall of the outer cylinder 13 and the outer wall of the inner cylinder 14 to remove minerals or scale on the surface of the cylinder wall, making cleaning more convenient, saving manpower and material resources, and reducing the difficulty of cleaning.

[0035] Embodiment 2

[0036] Based on Example 1, please refer to Figure 2 , Figure 4 and Figure 5 As shown, the specific improvements are as follows: a feed pipe 21 is provided at the top of the first effect concentrator 4, and both sides of the inner wall of the feed pipe 21 are fixedly connected with a limit plate 22 for limiting the installation position of the filter screen 23, and a filter screen 23 is provided on the top of the limit plate 22;

[0037] An L-shaped plate 24 is fixedly connected to the top of the filter screen 23, and the top of the feed pipe 21 is clamped with the L-shaped plate 24 through an installation assembly.

[0039] Embodiment 3

[0040] In conjunction with Example 1 and Example 2, please refer to Figure 1 and Figure 2 As shown, the specific improvements are as follows: a stirring assembly is arranged inside the inner cylinder 14, a second motor 17 is fixedly connected to the bottom of the outer cylinder 13, the stirring assembly includes a stirring rod 18 fixed to the output end of the second motor 17, a plurality of stirring blades 19 are fixedly connected to the surface of the stirring rod 18, and a stirring paddle 20 is fixedly connected to the bottom of the stirring rod 18.

[0041] Through the arrangement of the above structure, while heating, the rotation of multiple groups of stirring blades 19 and stirring paddles 20 can stir the medicine, accelerate the transfer of heat, make the medicine heated more evenly, and improve the heating efficiency.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0043] When in use, the medicine enters the first effect concentrator 4 through the feed pipe 21, and the filter 23 filters and removes impurities in the medicine to prevent impurities such as solid medicine residue from entering the concentrator and affecting the concentrated quality of the medicine. The low-pressure and low-temperature working medium absorbs external heat through the evaporator 1 and becomes a low-pressure and medium-temperature gas. Then, the low-pressure and medium-temperature gaseous working medium passes through the compressor 2 to do work and becomes a high-pressure and high-temperature gas. After the compressor 2, the compressed high-temperature and high-pressure gas enters the condenser 3, and the gas is converted into a high-temperature liquid, and then transported to the heating chamber 15 of the first effect concentrator 4 to heat and concentrate the medicine in the inner cylinder 14. At this time, the steam during heating provides a heat source for the second effect concentrator 5. When heating, the second motor 17 is started, and the stirring blade 19 and the stirring paddle 20 are driven to rotate through the stirring rod 18 to stir the medicine, so that the medicine is heated more evenly and the heating efficiency is improved.

[0044] After the filter 23 has been used for a long time, by pressing the protrusion 27, the protrusion 27 squeezes the spring 28 in the through groove 26, so that the protrusion 27 completely enters the protrusion 25, the L-shaped plate 24 can be moved upward, and the L-shaped plate 24 moves out of the protrusion 25, so that the filter 23 can be taken out of the feed pipe 21, which is convenient for cleaning the filter 23, opening the sealing plate 6, starting the first motor 9, driving the screw 10 to rotate, and under the sliding guide action of the slide plate 11, the cleaning component 7 can be driven to enter the heating chamber 15, and the nozzles 72 inside and outside the annular plate 71 evenly spray the cleaning agent in the heating chamber 15 up and down, and then after a period of static, the screw mechanism drives the cleaning component 7 to move up and down again, and the inner wall of the outer cylinder 13 and the outer wall of the inner cylinder 14 can be automatically scrubbed by the annular cleaning brush 75 to remove minerals or scale on the surface cylinder wall, making cleaning more convenient and saving manpower and material resources.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
