Description

Technical Field

[0001] The present invention relates to the technical field of concentrators, and specifically to a double-effect concentrator. Background Art

[0002] A concentrator refers to equipment for the concentration production process in industries such as traditional Chinese medicine, health products, natural seasonings, food additives, food, and chemical engineering. Since the invention of the concentrator, it has been widely used in many fields such as the chemical industry, pharmaceutical production and processing industry, ore processing industry, and sewage treatment.

[0003] The double-effect concentrator uses double-effect simultaneous evaporation, and the secondary steam is fully utilized, which not only saves the investment in boilers but also saves energy consumption. The energy consumption is reduced by 50% compared with that of a single-effect concentrator. The double-effect concentrator adopts an external heating natural circulation and vacuum negative pressure method, with a fast evaporation speed and a large concentration ratio. The liquid material is concentrated without foam in a fully sealed state. The medicinal liquid concentrated by this equipment is pollution-free and has a strong medicinal flavor.

[0004] However, in addition to the evaporation operation, the traditional double-effect concentrator also requires heat treatment. The double heating will result in relatively large energy consumption. Secondly, the concentration effect of the double-effect concentrator is related to the vacuum treatment environment in the instrument. Due to the fixed structure of the traditional double-effect concentrator, its vacuum effect is poor. Moreover, the double-effect concentrator uses double-effect simultaneous evaporation and then direct condensation. The traditional equipment structure may cause the product to transfer to the condensation treatment before the evaporation is completed, thereby resulting in a poor concentration effect of the product.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , an embodiment provided by the present invention: a double-effect concentrator, including a bottom plate 1. One end of the top of the bottom plate 1 is provided with a first-effect concentrator 3. The top of the first-effect concentrator 3 is provided with a top cover 9. The top of the top cover 9 is provided with a liquid inlet 10 for feeding liquid from a high place. The top end inside the first-effect concentrator 3 is provided with a first-effect evaporation chamber 6. The circumferential side wall of the first-effect evaporation chamber 6 is provided with a heating side wall 7. By providing the heating side wall 7 on the side walls of the first-effect evaporation chamber 6 and the second-effect evaporation chamber 16, while heating the product, evaporation treatment can be carried out. By combining the heating treatment and the evaporation treatment, energy can be effectively saved. Electric control devices 8 are symmetrically installed at the middle position outside the heating side wall 7. The electric control devices 8 control the heating treatment of the heating side wall 7. The bottom of the first-effect evaporation chamber 6 is provided with an evaporation chamber bottom plate 17. The bottom of the evaporation chamber bottom plate 17 is provided with a control rotating plate 18. One end of the cylindrical side of the control rotating plate 18 is provided with an L-shaped handle 19. By the cooperation of the evaporation chamber bottom plate 17 and the control rotating plate 18 at the bottom of the first-effect evaporation chamber 6 and the second-effect evaporation chamber 16, the rotation of the control rotating plate 18 by the L-shaped handle 19 realizes the opening and closing of the through holes 25 on the control rotating plate 18 and the evaporation chamber bottom plate 17, thereby facilitating the control of the evaporated products inside the first-effect evaporation chamber 6 and the second-effect evaporation chamber 16. The bottom end inside the first-effect concentrator 3 is provided with a first-effect condensation chamber 4. The first-effect condensation chamber 4 is used to condense the evaporated gas in the first-effect evaporation chamber 6. The bottom of the first-effect concentrator 3 is provided with a liquid extraction pipe 12. One end of the liquid extraction pipe 12 connected to the first-effect concentrator 3 is sealed inside the vacuum chamber 2 at the bottom of the first-effect concentrator 3 through a sealing ring 11. A vacuum pump 13 is provided between the first-effect concentrator 3 and the second-effect concentrator 15 to convey the articles, and the liquid extraction pipe 12 and the liquid infusion pipe 14 are sealed and connected through the sealing ring 11, thereby ensuring the sealing effect of the double-effect concentrator. One end of the top of the bottom plate 1 far from the first-effect concentrator 3 is provided with a second-effect concentrator 15. The top end inside the second-effect concentrator 15 is provided with a second-effect condensation chamber 20. The circumferential side wall of the second-effect evaporation chamber 16 has the same structure as the circumferential side wall of the first-effect evaporation chamber 6. The bottom end inside the second-effect concentrator 15 is provided with a second-effect condensation chamber 20. The second-effect condensation chamber 20 is used for condensing the gas in the second-effect evaporation chamber 16.

[0026] In this embodiment, through holes 25 are provided on both the control rotating plate 18 and the bottom plate 17 of the evaporation chamber, and the control rotating plate 18 is clamped to the bottom of the bottom plate 17 of the evaporation chamber through the rotating circular track 24 at the top.

[0027] Through holes 25 are provided on both the control rotating plate 18 and the bottom plate 17 of the evaporation chamber for connection; a fixed convex groove 1801 is provided on the control rotating plate 18, and a fixed concave groove 1701 is provided on the bottom plate 17 of the evaporation chamber (as Figure 5 shown). The fixed concave groove 1701 and the fixed convex groove 1801 are used in combination, so that: firstly, the structure has a certain sealing performance, thus separating the first-effect evaporation chamber 6 and the first-effect condensation chamber 4; secondly, the cooperation of the fixed concave groove 1701 and the fixed convex groove 1801 also has a positioning function (as Figure 4 shown).

[0028] As Figure 6 shown, in order to effectively reduce the pressure damage of the evaporation liquid, at the same time facilitate the control of the evaporation liquid condensation speed, and also extend the service life of the equipment, a stepped connection method can be set.

[0029] That is, a first-stage through hole 2501 and a second-stage through hole 2502 are also provided on the control rotating plate 18; the first-stage through hole 2501 and the second-stage through hole 2502 are coaxially arranged with the through hole 25. The first-stage through hole 2501 and the second-stage through hole 2502 are both blind holes, but the edges of the three are connected to allow the passage of steam. Thus, the slow entry of the evaporation liquid can be achieved, that is, the first-effect condensation chamber 4 is used to condense the evaporation gas in the first-effect evaporation chamber 6.

[0030] The top of the second-effect concentrator 15 is hermetically connected with an infusion pipe 14 through a sealing ring 11, and the infusion pipe 14 and the liquid extraction pipe 12 are connected through a vacuum pump 13. The bottom of the second-effect evaporation chamber 16 is provided with a bottom plate 17 of the evaporation chamber and a control rotating plate 18 having the same structure as that at the bottom of the first-effect evaporation chamber 6. The circumferential side wall installation structure of the second-effect condensation chamber 20 is the same as that of the circumferential side wall of the first-effect condensation chamber 4. The bottom of the second-effect concentrator 15 is provided with a second-effect liquid outlet pipe 23, and the bottom end of the second-effect liquid outlet pipe 23 penetrates through the bottom of the bottom plate 1 and is provided with a sealing cover 27. A condensation wall 5 is installed on the circumferential side wall of the first-effect condensation chamber 4, and the condensation wall 5 is connected to the condensation liquid storage tanks 21 at both bottom ends on both sides of the first-effect concentrator 3 through a delivery pump 26 inside the delivery pump box 22.

[0031] Working principle: First, place the device at the position to be used. Through the liquid inlet 10 installed at the top of the top cover 9, feed the product to be concentrated into the first-effect concentrator 3, and control the heating side wall 7 through the electric control device 8 at the middle position outside the heating side wall 7. The product is heated and evaporated inside the first-effect evaporation chamber 6. When the heating and evaporation reach a certain degree, control the cooperation between the rotating plate 18 and the through hole 25 on the evaporation chamber bottom plate 17 by rotating the L-shaped handle 19, so that the evaporated product enters the first-effect condensation chamber 4. The transfer pump 26 transports the condensate in the condensate storage tank 21 to the condensation wall 5, thereby condensing the evaporated product. Subsequently, the condensed product is transported to the second-effect concentrator 15 through the vacuum pump 13, and then the same operations as those of the first-effect concentrator 3 are carried out.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
