Description
Technical Field
[0001] The invention relates to the technical field of calcining Chinese medicinal materials, in particular to a calcining machine used for calcining Chinese medicinal materials in a pot. Background Art
[0002] In the field of Chinese medicine processing, the pot-lock calcination method is an important processing method, which is often used to prepare some specific Chinese medicines, such as blood charcoal. The heating method of traditional calcination equipment is relatively simple, and there is a lack of effective monitoring means to understand the state of the calcination process in real time. It is impossible to accurately judge whether the calcination process in different areas of the equipment is consistent. With the continuous development of the Chinese medicine industry, the quality requirements for Chinese medicine processing are getting higher and higher, and it is also required to improve production efficiency and reduce energy consumption. Traditional calcination equipment can no longer meet these needs. There is an urgent need for a new type of calcination machine that can achieve precise temperature control, real-time monitoring of the calcination process, and automatically adjust the heating power according to actual conditions to improve the quality and efficiency of Chinese medicine pot-lock calcination production.
[0003] For example, China Patent Publication No.: CN116270232A, the invention discloses a calcining device and a calcining method for Chinese herbal medicine slices, the invention provides a calcining device and a calcining method for Chinese herbal medicine slices that can uniformly carbonize Chinese herbal medicines and improve the calcination quality of Chinese herbal medicines, a calcining device for Chinese herbal medicine slices, including a calcining rack, a heater and a lower calcining pot, etc., the inner bottom wall of the calcining rack is connected to the heater, the lower middle part of the calcining rack is connected to the lower calcining pot, and also includes an exhaust mechanism and a stirring mechanism. The upper left side of the upper calcining pot is provided with an exhaust mechanism, and the upper right side of the upper calcining pot is provided with a stirring mechanism. The invention extracts the gas between the upper calcining pot and the lower calcining pot through the exhaust member, which can speed up the calcining speed and improve the calcining efficiency, and stirs the Chinese herbal medicines through the stirring rack, so that the Chinese herbal medicines are heated evenly, thereby achieving the effect of uniform carbonization of the Chinese herbal medicines.
[0004] The prior art still has the following problems:
[0005] The existing technology does not take into account the fact that during the continuous calcination of Chinese medicinal materials, the uneven residual heat inside the equipment and the uneven distribution of medicinal materials lead to different heating rates of medicinal materials in different areas of the equipment during the calcination process, which in turn leads to differences in the calcination process. The existing technology cannot judge the differences in the calcination process based on the smoke color characteristics that are highly representative of the production process, and cannot make targeted adjustments to the heating power, which affects the uniformity of the continuous calcination of medicinal materials. Summary of the invention
[0006] To this end, the present invention provides a calcining machine for the production of Chinese medicine calcination in a buckled pot, so as to overcome the problems in the prior art that the calcination process difference cannot be judged based on the smoke color characteristics with strong representativeness in the production process, and the heating firepower cannot be adjusted in a targeted manner.
[0007] To achieve the above object, the present invention provides a medicine calcining machine for Chinese medicine calcining production, comprising:
[0008] The machine body comprises a calcining bin for containing Chinese medicinal materials for calcining and a bin cover arranged on the top of the calcining bin for sealing the calcining bin;
[0009] A temperature control assembly, which is arranged at the bottom of the machine body, comprises a rotating shaft and a burner connected to the rotating shaft through a symmetrical bracket for heating the calcined medicine bin, and the burner rotates with the rotating shaft;
[0010] A plurality of monitoring components, including a plurality of monitoring pipeline loops arranged at preset intervals on the side of the calcining bin and a smoke detector arranged on each monitoring pipeline loop to obtain the color intensity of smoke in each monitoring pipeline loop;
[0011] Wherein, both ends of each monitoring pipeline loop are connected to the calcined medicine bin, so that the smoke in the calcined medicine bin passes through each monitoring pipeline loop;
[0012] A process analysis module, which is connected to a plurality of monitoring components, includes a region division unit and a smoke analysis unit, wherein the region division unit is used to divide the calcining bin into a plurality of calcining sub-regions according to the positions of the monitoring pipeline loops;
[0013] The smoke analysis unit is used to determine whether there is a difference in the forging process of each forging sub-area according to the fluctuation of the smoke color intensity of each monitoring pipeline loop within a preset time, and to screen the characteristic forging sub-area;
[0014] A production control module is connected to the process analysis module and the temperature control component, and is used to adjust the heating power of the burner on each characteristic forging sub-area according to the difference in smoke color intensity of each characteristic forging sub-area.
[0015] Furthermore, the area division unit is used to surround the central axis of the calcining bin and draw rays from the central axis to the surrounding areas at the same angle intervals, thereby dividing the internal area of the calcining bin into a number of calcining sub-areas, each of which corresponds to a unique monitoring component, and the central axis is perpendicular to the plane where the bin cover is located.
[0016] Furthermore, the monitoring pipeline loop also includes a switch valve arranged at a conducting position with the calcining medicine bin to control the flow of smoke at the conducting position, wherein a first switch valve is arranged at a conducting position far from the top of the calcining medicine bin, and a second switch valve is arranged at a conducting position close to the top of the calcining medicine bin.
[0017] Furthermore, each monitoring pipeline loop controls the second switch valve to close and controls the first switch valve to open for a preset time in response to the forging start instruction, so as to collect smoke in the monitoring pipeline loop within the preset time.
[0018] Furthermore, the smoke detector obtains smoke color intensity in each monitoring pipeline loop, including smoke red light intensity, smoke green light intensity and smoke blue light intensity.
[0019] Furthermore, the smoke analysis unit is used to calculate the standard deviation of the smoke red light intensity based on the smoke red light intensity in each monitoring pipeline loop, calculate the standard deviation of the smoke green light intensity based on the smoke green light intensity in each monitoring pipeline loop, and calculate the standard deviation of the smoke blue light intensity based on the smoke blue light intensity in each monitoring pipeline loop.
[0020] Furthermore, the smoke analysis unit is used to calculate a smoke color intensity fluctuation value based on the standard deviation of the smoke red light intensity, the standard deviation of the smoke green light intensity and the standard deviation of the smoke blue light intensity, and the smoke color intensity fluctuation value is positively correlated with the standard deviation of the smoke red light intensity, the standard deviation of the smoke green light intensity and the standard deviation of the smoke blue light intensity.
[0021] Further, the smoke analysis unit is used to compare the smoke color intensity fluctuation value with a preset smoke color intensity fluctuation reference value;
[0022] If the smoke color intensity fluctuation value is greater than the smoke color intensity fluctuation reference value, the smoke analysis unit determines that there is a difference in the forging progress between the forging sub-areas.
[0023] Furthermore, the smoke analysis unit is also used to calculate the intensity difference value between the smoke blue light intensity and the smoke blue light intensity comparison value in each monitoring pipeline loop, and select the forging sub-region where the monitoring pipeline loop where the absolute value of the intensity difference value is greater than the absolute value of the intensity difference reference is located as the characteristic forging sub-region;
[0024] The smoke blue light intensity contrast value is determined according to the average value of the smoke blue light intensity in each monitoring pipeline loop.
[0025] Furthermore, the production control module is also used to adjust the heating power of the burner on each characteristic forging sub-area according to the intensity difference value, and the heating power is positively correlated with the intensity difference value.
[0026] Compared with the prior art, the beneficial effect of the present invention lies in that, by setting a body, a temperature control component, several monitoring components, a process analysis module and a production control module, the present invention heats the calcining chamber through the temperature control component, obtains the smoke color intensity in each monitoring pipeline loop through the smoke detector, divides the calcining chamber into several calcining sub-areas through the area division unit, determines whether there is a calcining process difference in each calcining sub-area through the smoke analysis unit and screens the characteristic calcining sub-area, and adjusts the heating firepower of the burner to each characteristic calcining sub-area through the production control module, thereby realizing the judgment of the calcining process difference according to the smoke color characteristics with strong representativeness in the production process, and the targeted adjustment of the heating firepower, thereby ensuring the uniformity of the continuous calcination of medicinal materials and improving the quality and efficiency of the Chinese medicine calcination production.
[0027] In particular, the present invention divides the internal area of the calcining bin into several calcining sub-areas through the area division unit. Those skilled in the art can understand that by drawing rays from the central axis to the surrounding areas to divide the several calcining sub-areas, the temperature distribution characteristics of different positions of the calcining bin can be covered, thereby realizing a comprehensive division of the heated area of the calcining bin and improving the accuracy of monitoring the progress of medicinal material calcining.
[0028] In particular, the present invention monitors the switch valve set at the conduction position of the pipeline loop to control the flow of smoke. Those skilled in the art can understand that the medicinal materials contain various organic substances and a large amount of water. Under the high temperature conditions of calcination, these components will decompose to form smoke. The color of the smoke generated during the production process of the calcining machine can represent the progress of the calcination of traditional Chinese medicine. The present invention collects the smoke generated by each calcination sub-area during the calcination process by monitoring the opening and closing of the switch valve of the pipeline loop, thereby realizing the judgment of the calcination process difference based on the smoke color characteristics with strong representativeness in the production process, thereby improving the accuracy of calcination process monitoring.
[0029] In particular, the present invention obtains the red light intensity of the smoke, the green light intensity of the smoke, and the blue light intensity of the smoke in each monitoring pipeline loop through a smoke detector. Those skilled in the art will understand that the three primary colors of red, green, and blue have different wavelength ranges and characteristics, and can effectively distinguish different colors. The impact of environmental interference on color detection can be reduced through a comprehensive analysis of the three primary colors. During the calcination process of medicinal materials, the color of the smoke will change with the progress of calcination and changes in the composition of the medicinal materials. Collecting red, green, and blue primary color data can accurately identify color changes. The present invention obtains the red light intensity of the smoke, the green light intensity of the smoke, and the blue light intensity of the smoke in each monitoring pipeline loop through a smoke detector, thereby realizing the judgment of calcination process differences based on the smoke color characteristics with strong representation in the production process, thereby improving the accuracy of calcination process monitoring.
[0030] In particular, the present invention determines whether there is a difference in the calcination process of each calcination sub-area through a smoke analysis unit. Those skilled in the art can understand that the smoke color intensity fluctuation value can characterize the degree of difference in the distribution of heat in different areas in the calcination chamber. The larger the smoke color intensity fluctuation value, the more obvious the heat difference between the calcination sub-areas, and the smaller the smoke color intensity fluctuation value, the more uniform the heat distribution of each calcination sub-area. Therefore, the problem of uneven heating of medicinal materials is discovered in time, thereby improving the quality and efficiency of the production of Chinese medicine calcination in a pot.
[0031] In particular, the present invention adjusts the heating power of the burner to each characteristic calcining sub-area according to the intensity difference value through the production control module. Those skilled in the art can understand that, during the calcining process, the larger the absolute value of the intensity difference between the blue light intensity of the smoke in the calcining sub-area and the contrast value of the blue light intensity of the smoke, the more abnormal the heating rate of the medicinal materials in the calcining sub-area is, and the more it is necessary to adjust the calcining heating power of the area. Furthermore, it is realized that the calcining process difference can be judged according to the smoke color characteristics with strong representativeness in the production process, the heating power can be adjusted in a targeted manner, and the uniformity of continuous calcination of medicinal materials is improved.

[0048] A process analysis module, which is connected to a plurality of monitoring components, includes a region division unit and a smoke analysis unit, wherein the region division unit is used to divide the calcining bin 1 into a plurality of calcining sub-regions according to the positions of the monitoring pipeline loops 6;
[0049] The smoke analysis unit is used to determine whether there is a difference in the forging process of each forging sub-area according to the fluctuation of the smoke color intensity of each monitoring pipeline loop 6 within a preset time, and to screen the characteristic forging sub-area;
[0050] The production control module is connected to the process analysis module and the temperature control component, and is used to adjust the heating power of the burner 5 on each characteristic forging sub-area according to the difference in smoke color intensity of each characteristic forging sub-area.
[0051] Specifically, the present invention can drive the rotating shaft 3 to rotate by setting a motor, so that the rotating rotating shaft 3 drives the burner 5 to rotate through the symmetrical bracket 4. This is a common technical means used by technicians in this field and will not be repeated here.
[0052] Specifically, the present invention does not limit the specific structure of the burner 5. The combustion of the introduced gas is achieved through electronic ignition or spark ignition, and the size of the heating fire is controlled by controlling the amount of introduced gas. This is the prior art and will not be repeated here.
[0053] Specifically, the present invention does not limit the specific structure of the smoke detector 7. Preferably, it can be an RGB color sensor. Photosensitive elements such as photodiodes or photoresistors of the RGB color sensor can be used to sense light of different wavelengths respectively. These photosensitive elements convert the received light signals into electrical signals, and then obtain the light intensity values of the three primary colors of red, green and blue through internal circuit processing and calculation.

[0054] Specifically, the present invention does not limit the specific structure of the production control module, which can be composed of logic components. The logic components can be field programmable logic components, microprocessors, processors used in computers, etc., which will not be repeated here.
[0055] Specifically, the area division unit is used to surround the central axis of the calcined medicine bin 1 and draw rays from the central axis to the surrounding areas at the same angle intervals, thereby dividing the internal area of the calcined medicine bin 1 into a number of calcining sub-areas, each of which corresponds to a unique monitoring component, and the central axis is perpendicular to the plane where the bin cover 2 is located.
[0056] Specifically, the present invention does not limit the specific structure of the area division unit. Preferably, it can be a processor that performs virtual area division on the pre-built internal structure model of the calcined medicine bin 1 according to a pre-stored software algorithm. This is a prior art and will not be described in detail here.
[0057] Specifically, the present invention divides the internal area of the calcining bin 1 into several calcining sub-areas through the area division unit. Those skilled in the art can understand that by drawing rays from the central axis to the surrounding areas to divide several calcining sub-areas, the temperature distribution characteristics of different positions of the calcining bin 1 can be covered, thereby realizing a comprehensive division of the heated area of the calcining bin 1 and improving the accuracy of monitoring the progress of medicinal material calcining.
[0058] For more details, please refer to Figure 1 The monitoring pipeline loop 6 also includes a switch valve arranged at a conducting position with the calcining medicine bin 1 to control the flow of smoke at the conducting position, wherein a first switch valve 61 is arranged at a conducting position with a larger distance from the top of the calcining medicine bin 1, and a second switch valve 62 is arranged at a conducting position with a smaller distance from the top of the calcining medicine bin 1.
[0059] Specifically, each monitoring pipeline loop 6 controls the second switch valve 62 to close and controls the first switch valve 61 to open for a preset time in response to the forging start instruction, so as to collect smoke from the monitoring pipeline loop 6 within the preset time.
[0060] It is understandable that during the calcination of Chinese medicinal materials, smoke exhaust gases of different colors will be generated as the production process changes. The smoke exhaust gases float from the bottom of the calcination bin 1 to the top of the calcination bin 1. The present invention opens the first switch valve 61 to allow the smoke at the bottom of the calcination bin 1 to enter the monitoring pipeline loop 6. During this process, the second switch valve 62 is kept closed, so that the smoke entering the monitoring pipeline loop 6 remains in the monitoring pipeline loop 6.
[0061] Specifically, the present invention monitors the switch valve of the pipeline loop 6 at the conduction position to control the flow of smoke. Those skilled in the art will understand that medicinal materials contain various organic substances and a large amount of water. Under the high temperature conditions of calcination, these components will decompose to form smoke. The color of the smoke generated during the production process of the calcining machine can represent the progress of the calcination of traditional Chinese medicine. The present invention monitors the opening and closing of the switch valve of the pipeline loop 6, collects the smoke generated by each calcination sub-area during the calcination process, and further, realizes the judgment of the calcination process difference according to the smoke color characteristics with strong representativeness in the production process, thereby improving the accuracy of calcination process monitoring.
[0062] Specifically, the smoke detector 7 obtains the smoke color intensity in each monitoring pipeline loop 6, including the smoke red light intensity, the smoke green light intensity and the smoke blue light intensity.
[0063] Specifically, the present invention obtains the red light intensity of the smoke, the green light intensity of the smoke, and the blue light intensity of the smoke in each monitoring pipeline loop 6 through the smoke detector 7. Those skilled in the art can understand that the three primary colors of red, green, and blue have different wavelength ranges and characteristics, and can effectively distinguish different colors. The impact of environmental interference on color detection can be reduced by comprehensive analysis of the three primary colors. During the calcination process of medicinal materials, the color of the smoke will change with the progress of calcination and the change of medicinal material components. Collecting the red, green, and blue primary color data can accurately identify the color change. The present invention obtains the red light intensity of the smoke, the green light intensity of the smoke, and the blue light intensity of the smoke in each monitoring pipeline loop 6 through the smoke detector 7, thereby realizing the judgment of the calcination process difference according to the smoke color characteristics with strong representation in the production process, thereby improving the accuracy of calcination process monitoring.
[0064] Specifically, the smoke analysis unit is used to calculate the smoke red light intensity standard deviation S based on the smoke red light intensity in each monitoring pipeline loop 6. R , based on the smoke green light intensity in each monitoring pipeline loop 6, calculate the smoke green light intensity standard deviation S G And based on the smoke blue light intensity in each monitoring pipeline loop 6, the smoke blue light intensity standard deviation S is calculated. B .
[0065] Specifically, the smoke analysis unit is used to analyze the smoke red light intensity based on the standard deviation S R , the standard deviation of the green light intensity of the smoke S G And the standard deviation S of the smoke blue light intensity B Calculate the smoke color intensity fluctuation value W, the smoke color intensity fluctuation value W and the smoke red light intensity standard deviation S R , the standard deviation of the green light intensity of the smoke S G And the standard deviation S of the smoke blue light intensity B Positively correlated.
[0066] The smoke color intensity fluctuation value W can be calculated according to the following formula:
[0067] W=μ×S R +β×S G +γ×S B ;
[0068] Among them, μ is the weight coefficient of smoke red light intensity, β is the weight coefficient of smoke green light intensity, γ is the weight coefficient of smoke blue light intensity, and the smoke red light intensity weight coefficient μ, smoke green light intensity weight coefficient β and smoke blue light intensity weight coefficient γ are weight values selected by technical personnel in this field according to the degree of influence of smoke red light intensity, smoke green light intensity and smoke blue light intensity on the calculation results in historical data, μ+β+γ=1, preferably, the smoke red light intensity weight coefficient μ=0.3, the smoke green light intensity weight coefficient β=0.3, and the smoke blue light intensity weight coefficient γ=0.4.
[0069] Specifically, see Figure 4 As shown in FIG. 1 , it is a logic flow chart of the smoke analysis unit of an embodiment of the present invention for determining whether there is a difference in the forging process in each forging sub-area. The smoke analysis unit is used to compare the smoke color intensity fluctuation value W with the preset smoke color intensity fluctuation reference value W. 0 Make a comparison;
[0070] If the smoke color intensity fluctuation value W is less than or equal to the smoke color intensity fluctuation reference value W 0 , the smoke analysis unit determines that there is no difference in the forging process of each forging sub-area;
[0071] If the smoke color intensity fluctuation value W is greater than the smoke color intensity fluctuation reference value W 0 , the smoke analysis unit determines that there are differences in the forging processes of each forging sub-area.
[0072] Smoke color intensity fluctuation reference value W 0 The value of can be set according to the accuracy requirement of smoke color detection, and the smoke color intensity fluctuation reference value W 0 The smaller the value of is, the more accurately the subtle changes in smoke color intensity can be detected. Preferably, the smoke color intensity fluctuation reference value W can be set to 0 The value range is [25, 50].
[0073] Specifically, the present invention determines whether there is a difference in the calcination process of each calcination sub-area through a smoke analysis unit. Those skilled in the art can understand that the smoke color intensity fluctuation value can characterize the degree of difference in the distribution of heat in different areas in the calcination bin 1. The larger the smoke color intensity fluctuation value, the more obvious the heat difference between the calcination sub-areas; the smaller the smoke color intensity fluctuation value, the more uniform the heat distribution of each calcination sub-area. Thus, the problem of uneven heating of medicinal materials is discovered in time, thereby improving the quality and efficiency of the production of Chinese medicine calcination in a pot.
[0074] Specifically, the smoke analysis unit is also used to calculate the blue light intensity L of the smoke in each monitoring pipeline loop 6.B Comparison value of blue light intensity with smoke L B0 The intensity difference value L 1 , where L 1 =L B -L B0 , the absolute value of the intensity difference |L 1 |greater than the absolute value of the intensity difference reference|L 1 The calcining sub-region where the monitoring pipeline loop 6 is located is screened as a characteristic calcining sub-region;
[0075] Among them, the smoke blue light intensity contrast value L B0 According to the average value L of the blue light intensity of the smoke in each monitoring pipeline loop 6 2 Sure.
[0076] Intensity difference reference absolute value |L 1 The value of '| is based on the average value L of the blue light intensity of the smoke in each monitoring pipeline loop 6 2 Calculated, |L 1 '|=δ×L 2 , δ is the reference absolute value factor of the intensity difference, the value range of δ is [0.05, 0.2], the reference absolute value of the intensity difference |L 1 The smaller the value of '|, the more characteristic calcined sub-regions are screened out.
[0077] It is understandable that different colors of smoke exhaust gas will be produced during the calcination of Chinese medicinal materials as the production process changes. In response to the calcination start instruction, as the temperature gradually increases, the moisture in the raw materials is evaporated first, and a small amount of white water vapor smoke will be produced at this time. As the temperature continues to rise, the organic matter in the raw materials decomposes to produce thicker smoke. Compared with the thicker colored smoke, the blue light intensity L of the smoke in the RGB value of the smoke color is B There will be obvious changes, so the blue light intensity L of the smoke can be B The numerical change of can be used to judge the speed of calcination of Chinese medicinal materials. The blue light intensity L of the smoke in the RGB value of the smoke color B The smaller it is, the faster the progress of the calcination of traditional Chinese medicinal materials into the stage of organic matter decomposition.
[0078] Specifically, the production control module is also used to adjust the heating power of the burner 5 to each characteristic forging sub-area according to the intensity difference value, and the heating power is proportional to the intensity difference value L. 1 Positively correlated.
[0079] Specifically, the present invention adjusts the heating power of the burner 5 to each characteristic calcining sub-area according to the intensity difference value through the production control module. It can be understood by those skilled in the art that during the calcining process, the greater the absolute value of the intensity difference between the blue light intensity of the smoke in the calcining sub-area and the contrast value of the blue light intensity of the smoke, the more abnormal the heating rate of the medicinal material in the calcining sub-area is, and the more it is necessary to adjust the calcining heating power of the area. When the intensity difference value is positive, the blue light intensity L of the smoke in the RGB value of the smoke color is greater than the absolute value of the intensity difference between the blue light intensity of the smoke in the calcining sub-area and the contrast value of the blue light intensity of the smoke. B The larger the value, the slower the progress of the Chinese medicinal materials in the decomposition stage of organic matter. It is necessary to increase the heating power to ensure the uniformity of the medicinal materials. When the intensity difference value is negative, the blue light intensity L of the smoke in the RGB value of the smoke color B The smaller it is, the faster the progress of the calcination of traditional Chinese medicine entering the stage of organic matter decomposition, and the need to reduce the heating power to ensure the uniformity of the calcination of the medicine. The present invention judges the abnormal calcination fire area and adjusts the heating power of the corresponding area through the intensity difference value of the blue light intensity of the smoke and the contrast value of the blue light intensity of the smoke. Furthermore, it realizes the judgment of the calcination process difference according to the smoke color characteristics with strong representativeness in the production process, and the targeted adjustment of the heating power, thereby improving the uniformity of the continuous calcination of the medicine.
