Description

Technical Field

[0001] The utility model relates to the field of natural copper forging equipment, in particular to natural copper forging equipment. Background Art

[0002] In traditional Chinese medicine, some Chinese medicines are often used to promote bone healing and regeneration in the treatment of orthopedic diseases. Among them, the mineral Chinese medicine natural copper is one of the most important drugs for treating bone fractures and tendon injuries, and has a significant effect on promoting fracture healing. Chinese scholars have used modern scientific methods to study the mechanism of action of natural copper in the fracture healing process. They believe that natural copper can provide a variety of trace elements necessary for fracture healing, enhance the activity of a variety of enzymes, contribute to the formation of bone matrix and the deposition of calcium salts, and promote the formation of bone tissue. Modern pharmacological studies have shown that natural copper in Chinese medicine has the effect of promoting cell proliferation and differentiation. Single Chinese medicine natural copper can increase the number of calcified nodules of osteoblasts, and can promote the expression of insulin-like growth factor in osteoblasts cultured in vitro. In addition, it also has the advantages of sterilization, antiviral, no toxic side effects, and low price. Therefore, natural copper in Chinese medicine has a series of advantages as a bone-inducing material instead of growth factors for bone repair.

[0003] The processing method of natural copper has a long history. From ancient times to the present, repeated calcination and calcination quenching methods are mostly used. The quenching liquid includes vinegar, which is easy to crisp and helps to relieve blood stasis and relieve pain; wine quenching, which is used to promote blood circulation and dredge collaterals; hay water quenching, which is used to harmonize the dryness and strong nature; children's urine quenching, which is used to stop bleeding due to its salty and cold nature and its heat-dissipating and blood-stasis-dissipating effects. According to the processing specifications of various regions and the previous editions of the "Chinese Pharmacopoeia", its modern processing varieties mainly include: natural copper and calcined natural copper. The 2005 edition of the "Chinese Pharmacopoeia" stipulates: Natural copper raw products, that is, take the original medicinal materials, remove impurities, wash, dry, and smash. For calcined natural copper, take the clean natural copper, put it in a refractory container, heat it with high heat, take it out immediately after calcining it until it is red, put it into vinegar liquid for quenching, take it out after cooling, continue to calcine the vinegar quenching until it is dark brown, the appearance is brittle, the luster disappears, the texture is crisp, take it out, spread it out to cool, dry it and crush it.

[0004] According to the 2005 edition of the Chinese Pharmacopoeia, it is not difficult to find that natural copper needs to be calcined at high temperature until it is red and the red natural copper needs to be put into vinegar for quenching. This process requires the natural copper in a high temperature state to be transported. Since the natural copper has been crushed before forging, the purpose of crushing is to enable the natural copper to be fully heated during the forging stage. In the prior art, the crushed natural copper is stirred during the heating process so that the heated natural copper is evenly heated, thereby avoiding the situation where some natural copper cannot reach the state described in the method of the 2005 edition of the Chinese Pharmacopoeia due to uneven heating of the natural copper. It is also because the natural copper in powder form needs to be stirred to achieve a better forging state, which will also cause the natural copper in powder form to be not easy to arrange due to the high dispersion after being fully heated, so that the temperature of the natural copper drops during the transportation from the forging furnace to the vinegar quenching tank, so that the natural copper undergoing vinegar quenching cannot meet the temperature requirements, and the natural copper after vinegar quenching cannot meet the vinegar quenching state described in the 2005 edition of the Chinese Pharmacopoeia. And further, since the natural copper after being heated is in powder form, it is also easy to fall from the container during the transportation process. If the natural copper in a high temperature state contacts the body of the staff, it will also cause unpredictable harm to the staff. Therefore, there is room for improvement in the process in which the natural copper in powder form is uniformly heated in the forging equipment and the natural copper in powder form is heated and then transported to the vinegar quenching tank, so as to meet the requirements of the 2005 edition of the Chinese Pharmacopoeia for the natural copper after vinegar quenching, and to reduce the unpredictable personal injury caused by the spillage of natural copper to the staff, and thus can also correspondingly improve work efficiency and market promotion.

[0027] The usage of this product is as follows: Figures 1 to 3 As shown, the following steps are included:

[0028] S1. Place the natural copper raw materials that have been crushed and meet the particle size requirements and have been weighed into the feed hopper 16. When all the natural copper raw materials are placed in the feed hopper 16, open the first drive motor 19 and the first plug-in butterfly valve 14. At this time, the natural copper raw materials are transported to the first conveying pipe 2 through the fourth conveying pipe 13. Under the guidance of the shape of the first conveying pipe 2 itself and the drive of the first spiral blade 6, the natural copper raw materials enter the drum 4; then open the calcining nozzle 9, and intermittently open the first drive motor 19 so as to keep the drum 4 reversed first and then reversed under the condition that the calcining nozzle 9 keeps heating the drum 4.

[0029] S2, connect the sixth delivery pipe 35 to the bottom outlet of the storage tank for storing the external vinegar liquid source, and then open the booster pump 36 and the second stop valve 41. At this time, the external vinegar liquid source enters the vinegar quenching tank 12 after being driven by the booster pump 36. When the liquid level sensor 30 on the vinegar quenching tank 12 reaches the preset liquid level height, close the booster pump 36 and the second stop valve 41.

[0030] S3, when the calcining nozzle 9 keeps heating the drum 4 for a preset time, the second driving motor 40 is turned on, and the second driving motor 40 drives the second driving shaft 37 to rotate, thereby driving the stirring blade 38 to make a corresponding rotational motion, thereby stirring the vinegar liquid in the vinegar quenching tank 12; then, the driving cylinder 25 is turned on, and the driving cylinder 25 drives the driving rod 23 to move in a direction away from the drum 4, thereby driving the cover 10 to make a corresponding translational motion until the inlet end of the third conveying pipe 11 is located between the cover 10 and the drum 4; finally, the first driving motor 19 and the second plug-in butterfly valve 28 are turned on, and at this time, the natural copper raw material that has been calcined in the drum 4 enters the inner cavity of the third conveying pipe 11 through the drum 4 and the second conveying pipe 3 and then enters the inner cavity of the vinegar quenching tank 12, thereby entering the vinegar liquid in the inner cavity of the vinegar quenching tank 12 in a stirring state. Since the natural copper raw material that has been calcined enters the vinegar liquid in a high temperature state, the gas formed by the evaporation of the vinegar liquid is released outward through the exhaust valve 29.

[0031] S4, remove the end of the sixth delivery pipe 35 away from the fifth delivery pipe 31 from the storage tank for storing the vinegar liquid source outside and connect the end of the sixth delivery pipe 35 away from the fifth delivery pipe 31 to the sewage treatment equipment; then, when the natural copper raw material that has completed calcination and the vinegar liquid in the inner cavity of the vinegar quenching tank 12 in a stirring state are mixed for a preset time, open the booster pump 36 and the second stop valve 41 again and turn off the second drive motor 40 to discharge part of the vinegar liquid in the inner cavity of the vinegar quenching tank 12. When the liquid level sensor 30 on the vinegar quenching tank 12 drops to the preset liquid level height, turn off the booster pump 36 and the second stop valve 41, and finally open the first stop valve 32. The remaining vinegar liquid in the vinegar quenching tank 12 carries the natural copper that has completed vinegar quenching and is discharged from the first stop valve 32 and collected by the staff to wait for further processing in the next step.

[0032] Through this embodiment, uniform heating of powdered natural copper is achieved, and the heated powdered natural copper is transferred to vinegar quenching equipment, and the vinegar quenching step is completed. The manual operation is reduced in the process from forging to vinegar quenching of powdered natural copper, and the time interval from the forging stage to the vinegar quenching stage due to the need for manual operation is reduced, thereby indirectly reducing the heat loss of the calcined natural copper.
