Description

Technical Field

[0001] The invention belongs to the technical field of poultry feed manufacturing and relates to an intelligent control system for poultry feed production. Background Art

[0002] In the feed production process, melt spray granulation technology is favored because it can efficiently convert raw materials into uniform and stable granular feed. Among them, temperature control is one of the key links to ensure the quality of feed pellets. Improper temperature management will not only lead to feed nutrient loss and poor particle structure, but also may cause equipment failure, increase energy consumption and maintenance costs. In order to slow down the quality loss in the feed pellet production process, the melt spray granulation technology needs to be continuously improved.

[0003] There are some shortcomings in the existing technology: 1. During the operation of the feed melting equipment, especially the temperature adjustment stage, the internal components of the equipment may be frequently subjected to thermal stress of sudden cooling and heating due to the lack of a progressive temperature control strategy, thereby accelerating equipment fatigue and shortening equipment life.

[0004] 2. When the existing technology controls the temperature of the temperature operating equipment in the feed spray granulation process, most of them are based on the operating deviation value between the operating temperature of the operating equipment and the set temperature. There is a lack of combining the solidification state of the feed particles with the equipment operating temperature to judge, and it is impossible to adjust the temperature in real time according to the solidification state of the particles, thus affecting the granulation effect.

[0005] 3. When cooling feed pellets, the prior art fails to determine the temperature start buffer time of the cooling equipment according to the actual state of the feed pellets, which may lead to excessive temperature difference between the inside and outside of the feed pellets during the cooling process, causing pellet breakage and increased pulverization rate, thereby affecting the product quality of the feed.

[0042] The feed melting state module is used to feed various molten raw materials into a melter according to a formula ratio, heat them to a liquid state through steam to form a molten slurry, collect images of the molten slurry in real time, and detect the melting index of the molten slurry.

[0043] In a specific embodiment of the present invention, the melting index of the molten slurry is detected by identifying the fineness and mixing uniformity of the molten slurry from the molten slurry image, and evaluating the melting index of the molten slurry according to a preset evaluation formula.

[0046] The preset evaluation formula specifically obtains the melting index of the molten slurry by multiplying the fine density of the molten slurry by the mixing uniformity.

[0047] The melting machine temperature control module is used to determine the melting state of the molten slurry at the end time corresponding to the specified melting period, including the under-melted state and the standard-melted state, and adjust the melting temperature of the melting machine.

[0048] In a specific embodiment of the present invention, the steps of adjusting the melting temperature of the melting machine are as follows: comparing the melting index of the molten slurry with the preset buffer index in real time, detecting whether the melting index of the molten slurry reaches the preset buffer index within the specified melting period; if the melting index of the molten slurry reaches the preset buffer index at a certain moment within the specified melting period, the melting state of the molten slurry at the current moment is recorded as the standard melting state, and the temperature control mode of the melting machine is determined to be the cooling mode at the current moment, thereby uniformly reducing the temperature of the melting equipment to prevent the sudden cooling of the melting equipment from affecting the equipment's loss.

[0049] If the melting index of the molten slurry at the end time corresponding to the specified melting period does not reach the preset buffer index, the melting state of the molten slurry at the end time corresponding to the specified melting period is recorded as an under-melted state, and the temperature control mode of the melting machine is determined to be the heating mode at the end time, thereby increasing the temperature of the melting equipment and accelerating the melting reaction until the preset buffer index is reached, and then starting the heat reduction mode.

[0050] The preset buffer index is specifically: the molten slurry has not reached but is close to the desired molten state.

[0051] The present invention adjusts the melting temperature of the melting machine by detecting whether the melting index of the molten slurry reaches the standard within a reserved period, ensuring that the melting machine performs a slow temperature reduction operation within the reserved period, avoiding thermal stress concentration caused by sudden temperature drop in the melting equipment, thereby reducing mechanical fatigue and damage to internal components of the equipment and extending the overall service life of the equipment.

[0052] The molten slurry spraying granulation module is used to transport the molten slurry to the nozzle of the spraying equipment through a high-pressure pump to generate atomized droplets, which are collided and bonded with other solid mixed raw materials in powder form inside the granulator to form thermal particles, and then the solidified form of the thermal particles is detected.

[0053] In a specific embodiment of the present invention, the specific contents of detecting the solidification morphology of the thermal particles include: collecting thermal particles to make images, identifying shape characteristics of each thermal particle, identifying the shape characteristics of each thermal particle based on image recognition technology, and analyzing the shape uniformity standard, surface looseness, and surface gelatinization degree of the thermal particles.

[0054] Specifically, the shape indicators of the thermal particles include apparent chromaticity, shape area and edge contour, and internal pore volume.

[0055] The contents of analyzing the uniform shape standard, surface porosity, and surface gelatinization degree of the thermal particles are as follows: extracting the outline of each thermal particle and its apparent chromaticity, shape area, and edge contour from the thermal particle production image, and using a similarity calculation method to compare the corresponding apparent chromaticity, shape area, and edge contour of each thermal particle outline to obtain the similarity between the thermal particle outlines, which is used as the uniform shape standard of the thermal particles.

[0056] The bonding area between adjacent thermal particles is identified from the thermal particle production image, and this is used as an evaluation index to obtain the ratio between the bonding area and the preset reference bonding area, which is recorded as the apparent bonding degree of the thermal particles. .

[0057] Based on image recognition technology, the straightness of the edge line corresponding to the edge contour of each thermal particle is obtained The product of the apparent adhesion and its apparent surface porosity is recorded as the surface porosity of the thermal particles. , is the number of the thermal particle contour, .

[0058] The surface gelatinization degree is determined by the apparent chromaticity and internal pore volume of each thermal particle outline, that is, the internal structure image of each thermal particle outline is collected, and the internal pore volume of each thermal particle outline is extracted by image recognition technology. , calculate the surface gelatinization degree of thermal particles ,in For the The apparent chromaticity of the thermal particle outline, Preset regular color for thermal particles, Preset reference volume for interior holes.

[0059] Based on the shape uniformity standard of the thermal particles, it is determined whether the solidified morphology of the thermal particles is particle inhomogeneity.

[0060] Based on the surface porosity of the thermal particles, it is determined whether the cured state of the thermal particles is insufficient in hardness.

[0061] Based on the surface gelatinization degree of the thermal particles, determine whether the solidified state of the thermal particles is burnt material.

[0062] The method for determining whether the solidification morphology of the thermal particles is particle unevenness is as follows: comparing the shape uniformity standard of the thermal particles with a preset shape metric standard value; when the shape uniformity standard of the thermal particles exceeds the preset shape metric standard value, the solidification morphology of the thermal particles is recorded as particle unevenness.

[0063] The method for determining whether the solidified form of the thermal particles is insufficient in hardness is: comparing the surface porosity of the thermal particles with a preset porosity measurement standard value. When the surface porosity of the thermal particles exceeds the preset porosity measurement standard value, the solidified form of the thermal particles is recorded as insufficient in hardness.

[0064] The method for determining whether the solidified form of the thermal particles is a burnt material is as follows: the surface gelatinization degree of the thermal particles is compared with a preset gelatinization metric standard value. When the surface gelatinization degree of the thermal particles exceeds the preset gelatinization metric standard value, the solidified form of the thermal particles is recorded as a burnt material.

[0065] The temperature difference control module of the granulation equipment is used to determine the problem source equipment and its temperature control mode based on the solidification form of the thermal particles, and to correct the operating temperature of the problem source equipment accordingly.

[0066] In a specific embodiment of the present invention, the method of determining the problem source device and its temperature control mode is: When the solidification form of the thermal particles is uneven, the amount of thermal particles generated inside the granulator and the amount of molten slurry produced in the high-pressure pump of the spraying equipment are extracted from the equipment operation data control end, and the difference is used as the transportation retention amount of the molten slurry in the transportation pipeline , get the preset conventional delivery holdup ,when When , it indicates that the molten slurry is affected by the high temperature during the production process of the spraying equipment and causes losses, and then the problem source equipment is identified as the nozzle equipment corresponding to the spraying equipment or the conveying pipeline, and the temperature control mode of the problem source equipment is recorded as the downward adjustment mode.

[0067] ,when When the atomized droplets are generated, the thermal image acquisition technology is used to detect the morphology of the atomized droplets. The morphologies of the atomized droplets include uneven shapes and uniform shapes. If the atomized droplets are generated in an uneven shape, it indicates that the nozzle device of the spraying equipment is the problem source device, and the temperature of the nozzle device of the spraying equipment needs to be adjusted to make the atomized droplets smaller and evenly distributed, and then the temperature control mode of the problem source device is recorded as the upward adjustment mode; if the atomized droplets are generated in a uniform shape, it indicates that the atomization effect is ideal. The temperature setting at this time is recorded as a reference standard for subsequent production. At the same time, it reflects that the granulator equipment is too low in temperature, which hinders the solidification process of the material, making it difficult for the particles to form regular shapes, and then the granulator equipment is recorded as the problem source equipment, and the temperature control mode of the problem source equipment is recorded as the upward adjustment mode.

[0068] It is particularly noted that the specific detection method for the atomized droplet generation morphology is: through the thermal image acquisition technology, the thermal distribution image of the atomized droplets generated at the nozzle of the spraying equipment is collected and sprayed into the granulator. According to the above-mentioned molten slurry mixing uniformity identification method, the uniformity of the atomized droplet generation morphology is similarly identified, and it is compared with the preset uniformity threshold. When it exceeds the preset uniformity threshold, the atomized droplet generation morphology is recorded as uniform in shape; when it does not exceed the preset uniformity threshold, the atomized droplet generation morphology is recorded as uneven in shape.

[0069] When the solidified form of the thermal particles is insufficiently hard, it indicates that the temperature inside the granulator is too low, which is insufficient to promote the full gelatinization of the starch in the material, resulting in a loose internal structure of the particles. The granulator equipment is then recorded as the problem source equipment, and the temperature control mode of the problem source equipment is recorded as the upward adjustment mode.

[0070] When the solidified form of the thermal particles is burnt material, it indicates that the temperature inside the granulator is too high, causing the material to gelatinize. The granulator equipment is then recorded as the problem source equipment, and the temperature control mode of the problem source equipment is recorded as the downward adjustment mode.

[0071] In a preferred embodiment, the method for identifying whether the problem source equipment is the nozzle equipment corresponding to the shotcrete equipment or the conveying pipeline is as follows: extract the amount of atomized droplets generated at the nozzle of the shotcrete equipment from the equipment operation data control end, subtract it from the amount of molten slurry produced in the high-pressure pump body of the shotcrete equipment, and obtain the conveying retention amount of the molten slurry in the conveying pipeline, and then compare it with the preset reasonable value of the conveying retention amount. If it exceeds the preset reasonable value of the conveying retention amount, it indicates that the temperature of the conveying pipeline is too high, causing the moisture in the material to evaporate rapidly, making the material viscous or even partially solidified, thereby increasing its viscosity with the conveying pipeline. The conveying pipeline corresponding to the shotcrete equipment is recorded as the problem source equipment, and the operating temperature of the conveying pipeline is appropriately lowered to reduce the viscosity between the molten slurry and the conveying pipeline. Otherwise, it means that the molten slurry is lost due to high-temperature evaporation when it is sprayed out by the nozzle equipment corresponding to the shotcrete equipment, and then the nozzle equipment corresponding to the shotcrete equipment is recorded as the problem source equipment.

[0072] In a further preferred embodiment, the step of correcting the operating temperature of the problem source device is as follows: , extract the problem source equipment and its temperature control mode. When the problem source equipment is the nozzle equipment corresponding to the spraying equipment and its temperature control mode is the downward adjustment mode, is the operating temperature correction value of the nozzle equipment corresponding to the shotcrete equipment, It is the current operating temperature of the nozzle equipment corresponding to the shotcrete equipment.

[0073] , when the problem source device is the nozzle device corresponding to the spraying device and its temperature control mode is the upward adjustment mode, obtain the difference amplitude between the uniformity of the atomized droplet generation morphology and the preset uniformity threshold ,by It is the operating temperature correction value of the nozzle equipment corresponding to the shotcrete equipment.

[0074] , When the source equipment is the corresponding delivery pipeline of the shotcrete equipment, is the operating temperature correction value of the corresponding delivery pipeline of the shotcrete equipment, It is the current operating temperature of the delivery pipeline corresponding to the shotcrete equipment, and then the operating temperature of the delivery pipeline corresponding to the shotcrete equipment is corrected according to the upward adjustment mode.

[0075] , when the problem source equipment is a granulator equipment and its control mode is the upward adjustment mode, obtain the difference amplitude between the shape uniformity standard of the thermal particles and the preset shape metric standard value , the difference between the surface porosity and the preset porosity metric value ,by is the operating temperature correction value of the granulator equipment, It is the current operating temperature of the granulator equipment.

[0076] , when the problem source equipment is a granulator equipment and its control mode is the downward adjustment mode, obtain the difference between the surface gelatinization degree of the thermal particles and the preset gelatinization metric standard value ,by It is the operating temperature correction value of the granulator equipment.

[0077] Specifically, the current operating temperature of the nozzle device corresponding to the spraying equipment, the current operating temperature of the conveying pipeline corresponding to the spraying equipment, and the current operating temperature of the granulator equipment are all extracted from the equipment operation data control terminal.

[0078] The present invention determines the problem source equipment and its temperature control mode in the molten slurry spraying granulation process by detecting the solidification form of thermal particles, and corrects the operating temperature of the problem source equipment accordingly, which can provide in-depth understanding of the weak links in the production process, provide data support for further optimization of the entire production process, and achieve refined management and continuous improvement.

[0079] The cooling device startup temperature control module is used to transport the hot particles to the cooling device through the transition section for natural heat dissipation, and then evaluate the degree of breakage and loss of the hot particles during transportation in the transition section, and determine the temperature startup buffer time of the cooling device accordingly.

[0080] In a specific embodiment of the present invention, the corresponding content of evaluating the degree of breakage and loss of thermal particles during transportation in the transition section is: collecting morphological images of the thermal particles at the initial position and the terminal position corresponding to the transition section, comparing the two images, identifying the crack and damage texture characteristics of the thermal particles based on image recognition technology, and obtaining the proportion of the crack and damage texture area of ​​the thermal particles in the morphological image corresponding to the terminal position, which is recorded as the degree of breakage and loss of the thermal particles during transportation in the transition section.
