Description

Technical Field

[0001] This utility model provides a high-efficiency calcining furnace for Chinese medicinal materials, belonging to the technical field of Chinese medicinal material calcination equipment, and particularly relates to a high-efficiency calcining furnace for gypsum. Background Technology

[0002] A traditional Chinese medicine calcination furnace is a specialized piece of equipment used for the calcination and processing of Chinese medicinal herbs. It provides a controllable high-temperature environment to meet the specific calcination requirements of different herbs. Gypsum, a commonly used Chinese medicinal herb, undergoes a transformation in its medicinal properties after calcination, acquiring effects such as astringency, tissue regeneration, wound healing, and hemostasis.

[0003] When calcining gypsum, rapid temperature changes can easily cause cracks on the surface. To avoid this, a two-stage calcination method is typically used: a preheating stage and a dehydration stage. In the preheating stage, a lower temperature is used for slow heating to prevent cracking due to rapid temperature changes. In the dehydration stage, the temperature is increased to accelerate dehydration. However, continuous calcination requires repeated temperature adjustments within the furnace. Initially, a low-temperature preheating is needed, followed by an increase in temperature. However, it takes time for the furnace to reach the appropriate calcination temperature after the heating column or wire has been raised, inevitably reducing calcination efficiency. Furthermore, when the previous batch of gypsum is calcined, the furnace remains at a high temperature. Adding the next batch at this point can easily cause cracks. Therefore, it is necessary to wait for the furnace temperature to drop to the appropriate preheating temperature before adding new gypsum. The slow cooling rate after the furnace temperature rises is detrimental to the efficiency of continuous calcination. To address these issues, a high-efficiency calcination furnace for traditional Chinese medicine is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the two-stage calcination method for gypsum results in low continuous calcination efficiency.

[0005] To address the aforementioned problems, the proposed technical solution is as follows: a high-efficiency calcining furnace for traditional Chinese medicinal materials, comprising a furnace body with an end cover; a support plate fixedly installed on the inner wall of the furnace body, with a heating column installed within the support plate; a feed hole on the end cover and a discharge hole at the bottom of the furnace body; further comprising:

[0006] A breathable mesh frame is fixedly installed inside the furnace body; two interlocking partition plates are slidably installed inside the mesh frame, with a preheating layer above the partition plates and a calcination layer below the partition plates, and the heating column is positioned corresponding to the calcination layer; a sliding component capable of driving the partition plates to slide is provided on the furnace body.

[0007] The rotating motor and the stirring assembly are mounted on the end cover and are fixedly connected to the output shaft of the rotating motor. The stirring assembly passes through the preheating layer and the calcination layer.

[0008] As an improvement, a fixed plate is fixedly installed on the outer wall of the furnace body, and a sliding assembly is installed on the fixed plate; the sliding assembly is an electric telescopic rod, which is fixedly installed on the fixed plate, and the working end of the electric telescopic rod passes through the wire mesh frame and is fixedly connected to the partition plate.

[0009] As an improvement, the sliding component is provided with two sets corresponding to the partition plate, and the partition plate is provided with a number of evenly distributed ventilation holes.

[0010] As an improvement, the stirring assembly includes a rotating shaft, a first stirring blade, and a second stirring blade. The rotating shaft is fixedly connected to the output shaft of a rotating motor. The first stirring blade and the second stirring blade are both fixedly connected to the rotating shaft. The first stirring blade is located in the preheating layer, and the second stirring blade is located in the calcination layer.

[0011] As an improvement, the partition plate is provided with a through hole, which is located at the position where the two partition plates meet, and the rotating shaft passes through the through hole.

[0012] As an improvement, the bottom of the mesh frame is provided with a connection hole corresponding to the discharge hole, and a sealing plug for insertion into the connection hole is screwed into the discharge hole; the furnace body is provided with an air outlet.

[0013] The beneficial effects of this utility model are:

[0014] The area above the partition plate is the preheating layer, and the area below it is the calcination layer, with the heating columns corresponding to the calcination layers. By setting two heating layers within the same frame and aligning the heating columns with the calcination layers, different temperatures can be achieved in different functional layers. The preheating layer has a lower temperature for preheating gypsum, while the calcination layer has a higher temperature for calcining gypsum. The sliding partition plate allows gypsum to quickly move from the preheating layer to the calcination layer, reducing the waiting time for the furnace to heat up. Furthermore, once the calcined gypsum has been removed, or even without removal, new gypsum can be directly added to the preheating layer for preheating, improving the efficiency of continuous gypsum calcination.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] according to Figure 1-4 As shown: This utility model provides a high-efficiency calcining furnace for Chinese medicinal materials: it includes a furnace body 1, with an end cover 2 on the furnace body 1; a support plate 10 is fixedly installed on the inner wall of the furnace body 1, and a heating column 9 is installed inside the support plate 10; a feed hole 3 is opened on the end cover 2, and a discharge hole 5 is opened at the bottom of the furnace body 1; an air outlet 4 is opened on the furnace body 1; it also includes:

[0023] A permeable mesh frame 8 is fixedly installed inside the furnace body 1; two interlocking partition plates 16 are slidably installed inside the mesh frame 8, with a preheating layer 15 above the partition plate 16 and a calcination layer 18 below the partition plate 16, and the heating column 9 is positioned corresponding to the calcination layer 18; a sliding component capable of driving the partition plate 16 to slide is provided on the furnace body 1.

[0024] like Figure 3 , 4 As shown, a fixed plate 12 is fixedly installed on the outer wall of the furnace body 1, and a sliding assembly is installed on the fixed plate 12. The sliding assembly is an electric telescopic rod 11, which is fixedly installed on the fixed plate 12, and the working end of the electric telescopic rod 11 passes through the mesh frame 8 and is fixedly connected to the partition plate 16. The electric telescopic rod 11 allows for convenient sliding control of the partition plate 16; when the two partition plates 16 separate, the gypsum in the preheating layer 15 can quickly fall into the calcining layer 18. The sliding assembly has two sets corresponding to the partition plates 16, and the partition plates 16 have several evenly distributed vent holes 17 to ensure the hot air communication between the preheating layer 15 and the calcining layer 18.

[0025] The rotating motor 13 and the stirring assembly are mounted on the end cover 2. The stirring assembly is fixedly connected to the output shaft of the rotating motor 13 and passes through the preheating layer 15 and the calcining layer 18.

[0026] like Figure 4As shown, the stirring assembly includes a rotating shaft 14, a first stirring blade 20, and a second stirring blade 19. The rotating shaft 14 is fixedly connected to the output shaft of the rotating motor 13. Both the first stirring blade 20 and the second stirring blade 19 are fixedly connected to the rotating shaft 14. The first stirring blade 20 is located within the preheating layer 15, and the second stirring blade 19 is located within the calcining layer 18. Using a single rotating motor 13 and rotating shaft 14, the gypsum in both the preheating layer 15 and the calcining layer 18 can be stirred simultaneously, thereby increasing the uniformity of heating. Through holes are provided on the partition plates 16, located at the point where the two partition plates 16 meet. The rotating shaft 14 passes through these through holes, ensuring that the presence of the partition plates 16 does not affect the normal operation of the stirring assembly.

[0027] like Figure 2 , 3 As shown, the bottom of the mesh frame 8 is provided with a connecting hole 7 corresponding to the discharge hole 5, and a sealing plug 6 is screwed into the discharge hole 5 and inserted into the connecting hole 7. The gypsum in the calcined layer 18 can be taken out through the connecting hole 7 and the discharge hole 5.

[0028] The principle of this utility model

[0029] In the design of the furnace body 1 provided in this application, the heating column 9 corresponds to the position of the calcining layer 18, therefore the temperature of the calcining layer 18 is higher, while the preheating layer 15, being farther from the heating column 9, has a lower temperature. Figure 4 As shown, when using this application, gypsum is added to the preheating layer 15 through the feed hole 3 to preheat the gypsum. After preheating, the electric telescopic rod 11 is activated, which drives the partition plate 16 to slide away from the mesh frame 8, so that the gypsum in the preheating layer 15 falls directly into the calcination layer 18, and is immediately calcined using the high temperature of the calcination layer 18. Compared with the traditional integrated calcination furnace, there is no need to wait for the furnace body 1 to rise to the calcination temperature, which can achieve efficient calcination of gypsum.

[0030] When the gypsum is in the calcination layer 18 and the preheating layer 15 is empty, the electric telescopic rod 11 is activated to reset the partition plate 16. To ensure continuous and efficient calcination, new gypsum can be added directly to the preheating layer 15 through the feed hole 3, so that the mesh frame 8 can simultaneously perform both preheating and calcination. After calcination, the sealing plug 6 is opened, and the calcined gypsum is removed from the calcination layer 18. Then, the preheated gypsum in the preheating layer 15 is reintroduced into the calcination layer 18 for calcination. This cycle is repeated, which can greatly improve the efficiency of continuous calcination of gypsum.

[0031] During the calcination process, the rotating motor 13 can be started. Under the action of the first stirring blade 20 and the second stirring blade 19, the gypsum in the preheating layer 15 and the calcination layer 18 can be stirred at the same time, increasing the uniformity of heating and calcination.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
