Description

Technical Field

[0001] This invention relates to the field of rotary calcining furnace technology, specifically to a special integrated calcining and quenching furnace for seven-calcination and eight-quenching of actinolite and its processing technology. Background Technology

[0002] As a traditional Chinese medicinal material, the scientific and standardized processing techniques of actinolite directly determine its efficacy and safety. In traditional actinolite processing practices, conventional calcination and quenching methods are the main techniques used. However, these traditional methods have many core defects that urgently need to be addressed, which seriously restrict the clinical application value and industrial development of actinolite.

[0003] First, the traditional calcination and quenching method has limitations in optimizing efficacy. This process can only achieve the basic goals of removing some of the toxicity of yangqi stone and enhancing its warming, tonifying, kidney-tonifying, and astringent effects. It cannot specifically regulate the yin-yang and five-element attributes and meridian tropism of yangqi stone, making it difficult to meet the needs of precise matching of medicinal properties in clinical diagnosis and treatment. Second, potential safety risks have not been effectively eliminated. Existing yangqi stone products processed using traditional methods still primarily belong to the kidney meridian and have not completely removed the toxicity of the mineral. In clinical application, this can easily lead to adverse reactions such as liver yang hyperactivity, increasing the risk of medication. Third, the lack of a quality control system results in insufficient stability of efficacy. The traditional processing lacks standardized process parameter control and quality evaluation indicators. Different batches and products prepared by different processors show significant differences in the content of active ingredients and the intensity of pharmacological effects, making it impossible to guarantee the consistency of clinical efficacy.

[0004] To address the shortcomings of traditional processing methods, there is an urgent need to develop a refined processing technique for yangqi stone to achieve precise control over its medicinal properties, thoroughly reduce toxicity, and ensure efficacy stability. However, the realization of this refined processing technique relies heavily on specialized equipment. Existing equipment is insufficient to meet the stringent processing conditions required for refined processing, becoming a key bottleneck restricting the upgrading of yangqi stone processing technology.

[0005] Specifically, existing processing equipment is mostly of a split structure, requiring manual transfer of medicinal materials during calcination and quenching. This not only makes it impossible to achieve continuous calcination and quenching operations, but also easily leads to the medicinal materials coming into contact with oxygen during the transfer process, making it difficult to meet the requirements of the oxygen-free environment for refined processing. At the same time, manual operation makes it difficult to accurately control key parameters such as calcination temperature, constant temperature time, quenching time and number of cycles, which cannot guarantee the stability and standardization of the processing process. In addition, existing equipment lacks precise support and guiding mechanisms for the calcination and quenching of medicinal materials, making it difficult to ensure uniform heating and sufficient quenching of batches of medicinal materials, thus restricting the efficiency of industrial production and the uniformity of finished product quality. Summary of the Invention

[0006] This invention provides a special calcination and quenching integrated furnace and processing technology for seven-calcination and eight-quenching of actinolite, to solve the problem that existing calcination equipment is not easy to implement rapid quenching.

[0007] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0008] A special calcination and quenching integrated furnace for seven-calcination and eight-quenching of actinolite includes a rotary furnace mechanism, a quenching mechanism connected to one side of the rotary furnace mechanism, and a conveying mechanism disposed inside the rotary furnace mechanism.

[0009] The conveying mechanism includes an annular chain that drives inside the rotary furnace mechanism. Multiple limiting rings are installed on the annular chain, and multiple calcining cylinders are slidably connected inside the limiting rings. Mesh holes are opened on the side wall of the calcining cylinder.

[0010] The conveying mechanism also includes a pad, the portion of the pad inside the rotary furnace mechanism is flat, and the portion outside the rotary furnace mechanism is concave. Two arc-shaped baffles are connected to both sides of the concave surface. The concave surface of the pad and the two arc-shaped baffles together form a quenching tank. The quenching mechanism supplies quenching solution to the quenching tank.

[0011] During the ring chain drive, multiple calcining cylinders can move between the rotary furnace mechanism and the quenching tank, thereby calcining and quenching the actinolite.

[0012] Preferably, the quenching mechanism includes a first medicine box and a second medicine box, wherein the first medicine box and the second medicine box are respectively filled with medicine solution A and medicine solution B.

[0013] Preferably, the first medicine tank and the second medicine tank are connected to the quenching tank by a discharge pipe and a return pipe, and a water pump is connected to the discharge pipe.

[0014] Preferably, both the first medicine box and the second medicine box are fixedly connected to a bracket, and a cylinder is fixedly connected to the bracket. A piston plate is fixedly connected to the output end of the cylinder. The two piston plates slide on the first medicine box and the second medicine box respectively. The two cylinders are shortened respectively, so that the medicine soup A or medicine soup B in the quenching tank can flow back to the corresponding first medicine box or second medicine box through the corresponding discharge pipe.

[0015] Preferably, the rotary furnace mechanism includes a furnace body, a double-leaf door is installed on one side of the furnace body, and a sliding door is slidably connected to the other end. The sliding door has an opening for the calcining cylinder to pass through, and an upward-opening door is hinged to the opening.

[0016] Preferably, the conveying mechanism includes two rotating shafts rotatably connected to the furnace body, each of which is fixedly connected to a sprocket, and the annular chain drive is connected to the two sprockets.

[0017] Preferably, a counterweight is connected to one side of the sliding door. When the sprocket is driven, the limiting ring can push the sliding door to slide through the inner wall of the opening, and when the limiting ring moves out of the opening, the counterweight pulls the sliding door to reset.

[0018] When the limiting ring moves into the opening, it can push the upward-opening door to flip up and open.

[0019] Preferably, a limiting protrusion is provided on the side of the sliding door away from the counterweight, and the limiting protrusion abuts against the outer wall of the furnace body.

[0020] Preferably, a transmission rope is connected between the sliding door and the counterweight, a support rod is fixedly connected to the outer wall of the furnace body, a guide wheel is rotatably connected to the end of the support rod, and the transmission rope is wound around the guide wheel.

[0021] A process for processing actinolite through a seven-calcination and eight-quenching method, utilizing a dedicated integrated calcination and quenching furnace for seven-calcination and eight-quenching of actinolite, includes the following steps:

[0022] Material selection: Pure natural actinolite ore (Ca2(Mg,Fe)5Si8O) is selected. 22 (OH)2), the volume of the raw ore single element to be used is determined by the water displacement method to be 800±50ml, the appearance is bluish-gray base, the bluish distribution area is ≥70%, the surface has a typical silicate mineral layered cleavage structure, the raw ore of actinolite is raw actinolite, with a clear and regular wood grain-like crystal structure.

[0023] Crushing and washing: Mechanically crush the ore to a particle size of 5-7cm, and rinse with naturally flowing water until no obvious debris flows out;

[0024] Acid purification: The crushed ore is soaked in an acid solution containing high-concentration white vinegar with an acetic acid concentration of ≥15%, one part licorice, and one part Achyranthes bidentata extract at a ratio of 20:1 for twelve hours. The liquid surface covers the medicinal material by ten centimeters. After soaking, the ore is taken out and rinsed with running water until the pH is ≥5.

[0025] Preliminary soaking: The ore is placed in a quartz crucible and heated to 1000℃ in an environment with an oxygen content of ≤5%. Then it is immediately transferred to medicinal solution A for soaking for 72 hours. The ingredients of medicinal solution A are: 300 liters of water, 8 kg of fresh donkey penis (including eggs), 2 kg of fresh donkey kidney, 1 kg of Eucommia ulmoides, 1 kg of Achyranthes bidentata, 500 g of Poria cocos, 300 g of ginseng, and 800 g of wolfberry.

[0026] Seven quenchings and seven calcinations: The ore after initial soaking is placed in a calcining cylinder and heated at a constant temperature of 1400℃ for 30 minutes in an oxygen-free environment. The shaft rotates, driving each calcining cylinder to stay in the furnace for 30 minutes for heating. After that, it is removed and placed in a quenching tank containing medicinal solution A for no more than 20 seconds for quenching. The heating and quenching operation is repeated seven times for the ore in each calcining cylinder. During this process, inert gas is used to purge the calcining cylinder to isolate oxygen. After seven times, the ore is soaked in medicinal solution A for two hours until the liquid temperature is no more than 30 degrees Celsius.

[0027] Eighth calcination modification: The ore after the seventh quenching is cooled to room temperature with liquid, and then sealed and soaked in medicinal decoction B for 72 hours. The temperature of medicinal decoction B is maintained at 40±2℃. The composition of medicinal decoction B is: 50 liters of water, 1 kg of Cornus officinalis, 1 kg of Schisandra chinensis, 150 g of Galla chinensis, 300 g of carbonized human hair, and 800 g of cuttlebone. The ore is heated to 1500℃ and kept at a vacuum of ≤10Pa for one hour to dry the medicinal decoction B. Then it is cooled to room temperature in the furnace to obtain calcined actinolite with completely collapsed crystal structure, rough surface, pores, and irregular new phases formed by fracture.

[0028] Mixed preparation: Grind calcined yangqi stone into powder, and mix 120 parts of donkey penis powder, 90 parts of calcined yangqi stone powder, 60 parts of calcined dragon bone powder and 60 parts of cistanche powder to make a preparation.

[0029] The beneficial effects of this invention are analyzed as follows:

[0030] A special integrated calcination and quenching furnace for seven-calcination and eight-quenching of actinolite includes a rotary furnace mechanism, a quenching mechanism connected to one side of the rotary furnace mechanism, and a conveying mechanism disposed inside the rotary furnace mechanism. The conveying mechanism includes an annular chain that drives inside the rotary furnace mechanism. Multiple limiting rings are installed on the annular chain, and multiple calcining cylinders are slidably connected inside the limiting rings. The side walls of the calcining cylinders are provided with mesh holes. The conveying mechanism also includes a pad plate. The part of the pad plate inside the rotary furnace mechanism is flat, and the part outside the rotary furnace mechanism is concave. Two arc-shaped baffles are connected to both sides of the concave surface. The concave surface of the pad plate and the two arc-shaped baffles together form a quenching tank. The quenching mechanism supplies quenching solution into the quenching tank. When the annular chain is driven, the multiple calcining cylinders can move between the rotary furnace mechanism and the quenching tank, thereby calcining and quenching the actinolite.

[0031] The rotary furnace mechanism can be operated by electric heating. A conveying mechanism, including a ring chain, is located inside the rotary furnace mechanism. The ring chain drives multiple calcining cylinders connected to it, moving them inside and outside the rotary furnace mechanism. Actinolite raw material is placed inside the calcining cylinders. When the calcining cylinders are inside the rotary furnace mechanism, the actinolite is in a calcining state; when the calcining cylinders move outside the rotary furnace mechanism, they are in a quenching state. The portion of the pad inside the rotary furnace mechanism is flat, supporting the calcining cylinders and preventing them from shifting downwards relative to the limiting ring. This ensures that the calcining cylinders remain within the temperature range inside the rotary furnace mechanism. In the higher region, one end of the pad extends out of the rotary furnace mechanism, and the outer region is concave. The concave surface of the pad transitions to the flat surface with an arc shape, ensuring that the calcining cylinder can move smoothly on the pad surface. Two arc-shaped baffles symmetrically installed on both sides of the concave surface together with the concave surface form a quenching tank. The quenching tank is filled with medicinal soup, so that quenching can be performed after the calcining cylinder moves into the quenching tank. When quenching the raw materials in the calcining cylinder, the calcination and quenching time of the actinolite can be controlled by adjusting the running speed of the ring chain and the time interval between each run.

Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Examples, such as Figure 1-6As shown, a special calcination and quenching integrated furnace for seven-calcination and eight-quenching of actinolite includes a rotary furnace mechanism 100, a quenching mechanism 300 connected to one side of the rotary furnace mechanism 100, and a conveying mechanism 200 disposed inside the rotary furnace mechanism 100. The conveying mechanism 200 includes an annular chain 230 that drives through the rotary furnace mechanism 100. Multiple limiting rings 240 are installed on the annular chain 230, and multiple calcining cylinders 250 are slidably connected within the limiting rings 240. Mesh openings are provided on the side walls of the calcining cylinders 250. The conveying mechanism 200 also... The system includes a pad 260, the portion of which is flat inside the rotary furnace mechanism 100 and concave outside the rotary furnace mechanism 100. Two arc-shaped baffles are connected to both sides of the concave surface. The concave surface of the pad 260 and the two arc-shaped baffles together form a quenching tank 270. The quenching mechanism 300 supplies quenching solution into the quenching tank 270. When driven by the annular chain 230, multiple calcining cylinders 250 can move between the rotary furnace mechanism 100 and the quenching tank 270, thereby calcining and quenching the actinolite.

[0049] The working mechanism of the integrated calcination and quenching furnace for seven-stage and eight-stage calcination of actinolite provided in this embodiment is as follows:

[0050] The rotary furnace mechanism 100 can be operated by electric heating. A conveying mechanism 200 is located within the rotary furnace mechanism 100 and includes an annular chain 230. The annular chain 230 drives multiple calcining cylinders 250 connected to the annular chain 230, moving them inside and outside the rotary furnace mechanism 100. Actinolite raw material is placed inside the calcining cylinders 250. When the calcining cylinders 250 are inside the rotary furnace mechanism 100, the actinolite is in a calcining state. When the calcining cylinders 250 move outside the rotary furnace mechanism 100, they are in a quenching state. The portion of the pad 260 inside the rotary furnace mechanism 100 is flat, supporting the calcining cylinders 250 and preventing them from shifting downwards relative to the limiting ring 240. The calcining cylinder 250 is located in a high-temperature area inside the rotary furnace mechanism 100. One end of the pad 260 extends out of the rotary furnace mechanism 100, and the area on the outside is concave. The concave surface of the pad 260 and the flat surface are connected by an arc-shaped transition to ensure that the calcining cylinder 250 can move smoothly on the surface of the pad 260. Two arc-shaped baffles symmetrically installed on both sides of the concave surface together with the concave surface form a quenching tank 270. The quenching tank 270 is filled with medicinal soup, so that quenching can be performed after the calcining cylinder 250 moves into the quenching tank 270. When quenching the raw materials in the calcining cylinder 250, the running speed of the ring chain 230 and the time interval of each run are adjusted to control the calcination and quenching time of the actinolite.

[0051] Among the optional methods in this embodiment, the more preferred one is:

[0052] The quenching mechanism 300 includes a first medicine box 310 and a second medicine box 320, which are respectively filled with medicine solution A and medicine solution B.

[0053] During the process of calcining and quenching actinolite seven times, the medicinal soup A in the first medicine box 310 is poured into the quenching tank 270 to perform seven quenching operations on the actinolite. After the actinolite in each calcining cylinder 250 has undergone seven calcinations and seven quenchings, all calcining cylinders 250 on the limiting rings 240 are removed and soaked in the medicinal soup A for two hours until the temperature of the medicinal soup A is not greater than 30 degrees. During the calcination and quenching process, when the calcining cylinders 250 are moved out and into the rotary furnace mechanism 100 and before the calcining cylinders 250 are completely immersed in the quenching tank 270, the calcining cylinders 250 are purged with inert gas to ensure that the actinolite in the calcining cylinders 250 does not come into contact with oxygen.

[0054] All calcination cylinders 250 can be placed directly into the quenching tank 270 for soaking, or a separate container can be used for soaking.

[0055] Among the optional methods in this embodiment, the more preferred one is:

[0056] The first medicine box 310 and the second medicine box 320 are connected to the quenching tank 270 by a discharge pipe 361 and a return pipe 362, and a water pump 360 is connected to the discharge pipe 361.

[0057] The first medicine tank 310 and the second medicine tank 320 can be set to temperature control type. During the quenching process of actinolite, the water pump 360 connected to the first medicine tank 310 runs, so that the medicine solution A in the quenching tank 270 and the medicine solution A in the first medicine tank 310 are in an exchange state, ensuring that the medicine solution in the quenching tank 270 will not be too hot. A filter screen can also be set on the return pipe 362 to prevent actinolite slag from entering the first medicine tank 310.

[0058] Among the optional methods in this embodiment, the more preferred one is:

[0059] A bracket 330 is fixedly connected to both the first medicine box 310 and the second medicine box 320. A cylinder 340 is fixedly connected to the bracket 330. A piston plate 350 is fixedly connected to the output end of the cylinder 340. The two piston plates 350 slide on the first medicine box 310 and the second medicine box 320 respectively. The two cylinders 340 are shortened respectively, so that the medicine soup A or medicine soup B in the quenching tank 270 can flow back to the corresponding first medicine box 310 or second medicine box 320 through the corresponding discharge pipe 361.

[0060] When cylinder 340 extends, it can drive piston plate 350 to move down into the corresponding medicine box, so that the medicine in the medicine box is forced out into quenching tank 270 through discharge pipe 361. When cylinder 340 is extended, water pump 360 on the corresponding medicine box runs, so that the medicine in quenching tank 270 and medicine box are in an exchange state. After quenching, cylinder 340 in the extended state is shortened, so that piston plate 350 moves up, so that negative pressure is generated in the corresponding medicine box, and the medicine in quenching tank 270 is drawn back into the corresponding medicine box.

[0061] Among the optional methods in this embodiment, the more preferred one is:

[0062] The rotary furnace mechanism 100 includes a furnace body 110. A double-leaf box door 120 is installed on one side of the furnace body 110, and a sliding door 130 is slidably connected to the other end. An opening 131 is provided on the sliding door 130 for the calcining cylinder 250 to pass through, and an upward-opening door 132 is hinged to the opening 131.

[0063] After the double-door 120 is opened, the port of the furnace body 110 forms a discharge port. The ring chain 230 is controlled to run, so that multiple limit rings 240 are aligned with the discharge port one by one. Then, the calcining cylinder 250 containing actinolite is placed into the limit ring 240. At this time, the pad 260 supports the calcining cylinder 250, and the ring chain 230 drives the calcining cylinder 250 to move through the limit ring 240.

[0064] After placing the calcining cylinder 250 completely behind the limiting ring 240, close the double-leaf box door 120, start the furnace body 110 to heat the yangqi stone, heat it to a suitable temperature and keep it at that temperature, control the ring chain 230 to run, so that the limiting ring 240 drives the calcining cylinder 250 to move to the sliding door 130 and push open the upturned door 132 connected to the opening 131 of the sliding door 130. At this time, the calcining cylinder 250 can enter the quenching tank 270.

[0065] Among the optional methods in this embodiment, the more preferred one is:

[0066] The conveying mechanism 200 includes two rotating shafts 210 rotatably connected inside the furnace body 110, and sprockets 220 are fixedly connected to each of the two rotating shafts 210. A ring chain 230 is driven to the two sprockets 220.

[0067] One of the rotating shafts 210 is driven by an external servo motor. The timing and speed of the servo motor are controlled by the control system, which sets the dwell time of the calcining cylinder 250 in the furnace body 110 and the quenching tank 270.

[0068] Among the optional methods in this embodiment, the more preferred one is:

[0069] A counterweight 170 is connected to one side of the sliding door 130. When the sprocket 220 is driven, the limiting ring 240 can push the sliding door 130 to slide through the inner wall of the opening 131. When the limiting ring 240 moves out of the opening 131, the counterweight 170 pulls the sliding door 130 back to its original position. When the limiting ring 240 moves into the opening 131, it can push the flip-up door 132 to flip up and open.

[0070] The counterweight 170 controls the initial position of the sliding door 130, so that the opening 131 on the sliding door 130 corresponds to the position of the calcining cylinder 250 to be moved out, ensuring that the calcining cylinder 250 to be moved out can move into the opening 131. At this time, the calcining cylinder 250 can push the flip-up door 132 to flip up to open. As the annular chain 230 continues to run, the limiting ring 240 can push the sliding door 130 to slide through the inner wall of the opening 131, ensuring that the calcining cylinder 250 can stably enter the quenching tank 270. As the annular chain 230 continues to run, the limiting ring 240 can move out of the opening 131. At this time, the counterweight 170 pulls the sliding door 130 to reset, and the flip-up door 132 swings down under gravity, causing the opening 131 to close, so that the furnace body 110 is in a closed state again to isolate oxygen.

[0071] Among the optional methods in this embodiment, the more preferred one is:

[0072] A limiting protrusion is provided on the side of the sliding door 130 away from the counterweight 170, and the limiting protrusion abuts against the outer wall of the furnace body 110.

[0073] The limiting protrusion restricts the position of the sliding door 130 when the counterweight 170 pulls the sliding door 130 to reset, preventing the sliding door 130 from detaching from the furnace body 110.

[0074] Among the optional methods in this embodiment, the more preferred one is:

[0075] A transmission rope 160 is connected between the sliding door 130 and the counterweight 170. A support rod 140 is fixedly connected to the outer wall of the furnace body 110. A guide wheel 150 is rotatably connected to the end of the support rod 140. The transmission rope 160 is wound around the guide wheel 150.

[0076] The transmission rope 160 connects the counterweight 170 to the sliding door 130. The support rod 140 provides installation support for the guide wheel 150, and the guide wheel 150 guides the transmission rope 160, so that the downward traction force of the counterweight 170 due to gravity is changed into the driving force for the sliding door 130 to slide and reset laterally.

[0077] like Figures 1-14 As shown, a process for processing actinolite using a seven-calcination and eight-quenching method utilizes a dedicated integrated calcination and quenching furnace for actinolite, and includes the following steps:

[0078] Material selection: Pure natural actinolite ore (Ca2(Mg,Fe)5Si8O) is selected. 22 (OH)2), the volume of the raw ore single unit to be used was determined by the water displacement method to be 800±50ml, the appearance was bluish-gray base, the bluish distribution area was ≥70%, and the surface had a typical silicate mineral layered cleavage structure.

[0079] Crushing and washing: Mechanically crush the ore to a particle size of 5-7cm, and rinse with naturally flowing water until no obvious debris flows out;

[0080] Acid purification: The crushed ore is soaked in an acid solution containing high-concentration white vinegar with an acetic acid concentration of ≥15%, one part licorice, and one part Achyranthes bidentata extract at a ratio of 20:1 for twelve hours. The liquid surface covers the medicinal material by ten centimeters. After soaking, the ore is taken out and rinsed with running water until the pH is ≥5.

[0081] Preliminary soaking: The ore is placed in a quartz crucible and heated to 1000℃ in an environment with an oxygen content of ≤5%. Then it is immediately transferred to medicinal solution A for soaking for 72 hours. The ingredients of medicinal solution A are: 300 liters of water, 8 kg of fresh donkey penis (including eggs), 2 kg of fresh donkey kidney, 1 kg of Eucommia ulmoides, 1 kg of Achyranthes bidentata, 500 g of Poria cocos, 300 g of ginseng, and 800 g of wolfberry.

[0082] Seven quenchings and seven calcinations: The ore after initial soaking is placed in a calcining cylinder and heated at a constant temperature of 1400℃ for 30 minutes in an oxygen-free environment. The shaft rotates, driving each calcining cylinder to stay in the furnace for 30 minutes for heating. After that, it is removed and placed in a quenching tank containing medicinal solution A for no more than 20 seconds for quenching. The heating and quenching operation is repeated seven times for the ore in each calcining cylinder. During this process, inert gas is used to purge the calcining cylinder to isolate oxygen. After seven times, the ore is soaked in medicinal solution A for two hours until the liquid temperature is no more than 30 degrees Celsius.

[0083] Eighth calcination modification: The ore after the seventh quenching is cooled to room temperature with liquid, and then sealed and soaked in medicinal decoction B for 72 hours. The temperature of medicinal decoction B is maintained at 40±2℃. The composition of medicinal decoction B is: 50 liters of water, 1 kg of Cornus officinalis, 1 kg of Schisandra chinensis, 150 g of Galla chinensis, 300 g of carbonized human hair, and 800 g of cuttlebone.
