Description

Technical Field

[0001] The utility model relates to the technical field of grain and oil food production, in particular to an online moisture regulation system for powdery particles. Background Art

[0002] In modern wheat flour milling, after wheat is conditioned by water, it undergoes a series of grinding, sieving, and grading processes to produce different in-process and finished products. The in-process products are then further ground, sifted (purified), and graded. Flour of similar quality from each sifted process is then aggregated through conveying equipment to produce finished products and by-products of varying grades. After inspection and sifting, the flour is either stored in a temporary silo or directly packaged for storage. In existing processes, moisture adjustment is not performed in any of the various systems after conditioned wheat. However, due to the varying moisture loss in different flour milling processes, depending on the requirements of different flour qualities, the moisture content of the flour in the flour milling process, including at the front, middle, and back stages, and in the by-products, varies significantly.

[0003] Therefore, a system capable of online moisture adjustment of powdered particles was developed. This system was deployed at the back end of each different process step in the product and at the front end of the inspection screen. This system selectively adjusts the moisture content of the finished products or by-products obtained from each process before entering the inspection screen, based on their moisture content. This increases the moisture content of low-moisture online powdered particles, ensuring that they meet national moisture standards, meet storage conditions and product shelf life, increase yields, and improve the company's economic benefits. Furthermore, depending on the situation, the moisture content of high-moisture online powdered particles can also be reduced to meet the requirements of online moisture adjustment of powdered particles.

[0022] Preferably, the method of use further comprises:

[0023] Receive the material signal fed back by the first material level sensor.

[0025] Preferably, the method of use further comprises:

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] The utility model provides an online moisture regulation system for powdered particulate matter, comprising a three-way distributor A1, a three-way pipeline 2, a material homogenizing bin 3, a shaker 4, an air shutoff device 5, a supply source station 6 and a negative pressure lifting system. The three-way distributor A1 and the three-way pipeline 2 are both arranged on the input pipeline of the inspection screen 7, and the three-way pipeline 2 is located between the three-way distributor A1 and the inspection screen 7. The other output end of the three-way distributor A1 is connected to the feed port of the material homogenizing bin 3 through a pipeline, and the discharge port of the material homogenizing bin 3 is connected to the air inlet of the shaker 4 through a pipeline. The air shutoff device 5 is arranged at the lower end of the shaker 4, and its inlet is connected to the discharge port of the shaker 4. The outlet of the air shutoff device 5 is connected to the other input end of the three-way pipeline 2 through a pipeline, and the outlet of the supply source station 6 is connected to the spray assembly of the material homogenizing bin 3 through a pipeline, and the negative pressure lifting system is connected to the exhaust port of the shaker 4. In order to facilitate the observation of the direction of the entire system, straight lines and arrows are used instead of pipes to indicate the connection relationship between each device.

[0039] Among them, the three-way material distributor has several starting modes such as electro-hydraulic, electric, pneumatic, and manual, so it is also called electro-hydraulic three-way material distributor, electric three-way material distributor, pneumatic three-way material distributor, and manual three-way material distributor. In this embodiment, the three-way material distributor A can be any of the electro-hydraulic three-way material distributor, electric three-way material distributor, and pneumatic three-way material distributor, preferably a pneumatic three-way material distributor, which is convenient for connection with the control system. According to the feedback information, the material reversal is controlled so that the material selectively enters the detection screen or the material homogenization bin.

[0040] The inspection screen is an original process equipment and is electrically connected to the control system. The inlet of the inspection screen is connected to the outlet of the previous equipment through an input pipe. This system is arranged between the inspection screen and the previous equipment. The control system obtains the moisture content of the powdery particulate material and compares it with the standard moisture content to determine whether the powdery particulate material enters the inspection screen or the system.

[0041] In this embodiment, electrical equipment, such as three-way distributor A, air lock, source station and negative pressure lifting system are all electrically connected to the control system of the original process, which includes an electric control cabinet, control software installed in the electric control cabinet, etc. Figure 1-Figure 2 The original process's electrical control cabinet is shown in the figure. An air compressor system is also located outside the workshop. This system powers pneumatic equipment. When using a pneumatic three-way distributor, three-way distributor A requires compressed air as a power source. The high-pressure pulse dust collector also requires compressed air for dust removal.

[0042] Furthermore, in modern wheat flour milling, after being moistened with water, wheat is then ground, screened, and graded in a sequential process to produce different in-process and finished products. Since the in-process products are further ground, screened (purified), and graded, flour of similar quality from each process is collected through conveying equipment and, depending on the requirements of the flour quality, passed through a screening inspection screen before being placed in a temporary storage bin or directly packaged for storage. Due to the varying moisture loss in different flour paths, the moisture content of the front, middle, and back paths, as well as in the by-products, varies significantly. Since this system is deployed ahead of the inspection screen, the original process route remains unchanged. Therefore, while the original process remains unchanged, the moisture content of the product obtained from one process may meet or be below the standard, while the moisture content of the product obtained from another process may meet or exceed the standard. The situation in which the moisture content of the product obtained from one process is alternately below the standard and then above the standard is avoided. Therefore, the supply station is either the high-pressure water pump station 6-1 or the high-pressure steam generator 6-2. Depending on the moisture content of the products from each process, the high-pressure water pump station or the high-pressure steam generator is selectively deployed when implementing this system.

[0043] In the present embodiment, the material homogenizing bin 3 has two feed ports, and correspondingly, the system further includes a three-way divider B 8, the other output end of the three-way divider A 1 being connected to the input end of the three-way divider B 8 through a pipeline, and the two output ends of the three-way divider B 8 being connected to the two feed ports of the material homogenizing bin 3 through pipelines. The incoming material output by the three-way divider A is divided into two parts by the three-way divider B, which respectively enter the two feed ports of the material homogenizing bin for moisture adjustment. According to the experience of long-term use of three-way pipe material distribution, the material will not be divided into two even parts by the three-way pipe, and there will always be more in one part and less in the other. Therefore, the three-way divider B is preferably a manual three-way divider, which is manually debugged only when the system is installed to ensure that the material is divided into two relatively even parts and enters the material homogenizing bin.

[0044] Currently, flour mills use three conveying methods: negative pressure conveying, positive pressure conveying, and mechanical conveying. Most mills utilize pneumatic conveying (negative pressure) technology to complete material conveying tasks within the flour milling system. As long as the air volume and pressure meet the requirements, employing a high-pressure pulse dust collector and a high-pressure centrifugal blower is entirely feasible. In this embodiment, the negative pressure material conveying system includes a high-pressure pulse dust collector 9 and a high-pressure centrifugal blower 10. The air inlet of the high-pressure pulse dust collector 9 is connected to the exhaust port of the Shakron 4 via a duct, and the air outlet of the high-pressure pulse dust collector 9 is connected to the air inlet of the high-pressure centrifugal blower 10 via a duct. The air outlet of the high-pressure centrifugal blower 10 is connected to a duct, and the duct extends outside the workshop.

[0045] like Figure 3-Figure 8 As shown, the structure of the material homogenizing bin 3 in this system is as follows. Specifically, it includes a frame 3-1, a bin body 3-2 arranged on the frame, and a hopper 3-3 arranged at the bottom of the bin body and connected to the bin body. Two feed bins 3-4 connected thereto are symmetrically arranged on the top of the bin body 3-3. A feed port 3-41 is arranged on the top of the feed bin 3-4. An air inlet is opened on the top of the bin body located between the two feed bins 3-4. First homogenizing components 3-5 corresponding to the bottom of the feed bin are respectively arranged on the left and right sides of the bin body 3-2. Second homogenizing components 3-6 are respectively arranged on the left and right sides of the bin body. The second homogenizing component 3-6 is located below the first homogenizing component 3-5. A spray component is arranged inside the bin body, and the spray component is connected to the source station. The lower end of the hopper 3-3 is detachably connected to a discharge pipe 3-7 through a flange, and the opening of the discharge pipe forms a discharge port. Since the discharge pipe is detachably arranged at the lower end of the hopper, the direction of the discharge port of the discharge pipe can be adjusted according to the on-site conditions.

[0046] During use, the material enters through the three-way distributor B and is relatively evenly divided into two parts, which enter two symmetrical feed bins. During the falling process, the two parts of material pass through the first and second leveling components below the feed bins, forming a dispersed material thin layer waterfall. The two thin material waterfalls form an angle with each other. After a certain delay, the source station is activated to deliver water or air to the spray assembly. The spray assembly sprays high-pressure water or high-pressure superheated steam towards the cross-material waterfall. Under the action of negative pressure, it is fully mixed with the material. The mixed material falls into the hopper and is drawn out from the discharge port of the discharge pipe. It enters the Shakron for gas-solid separation. Under the action of the negative pressure lifting system, air continuously enters the silo from the air inlet at the top of the silo. Under the action of the air, the material can be fully mixed and drawn out through the discharge pipe.

[0047] In this embodiment, the first material refining assembly 3-5 includes a first fixed plate 3-51 and a first adjustment plate 3-52. The first fixed plate 3-51 is disposed on the top inner side of the silo body 3-1 and arranged along the length of the feed silo. Its ends are attached to the inner sidewall of the silo. The first fixed plate 3-51 has a downward-facing vertical plate and an inclined plate connected to the vertical plate at an obtuse angle. The first adjustment plate 3-52 is disposed on the inner sidewall of the silo below the feed silo and can move up and down along the inner sidewall. The first adjustment plate 3-52 is arranged along the length of the feed silo. Its ends extend to the inner sidewall of the silo but are not fixed. The first adjustment plate 3-52 has an inclined plate connected at an obtuse angle. The lower end of the inclined plate of the first adjustment plate 3-52 cooperates with the upper surface of the oblique edge of the first fixed plate 3-51 to form a first material refining channel. Material passes through the first material refining channel to form a thin layer of material.

[0048] The first adjustment plate 3-52 moves up and down along the inner wall of the hopper body to adjust the size of the first material distribution channel. Specifically, the first adjustment plate 3-52 is adjustably mounted on the inner wall of the hopper body via a plurality of star-shaped handles 3-8, which are spaced apart along the length of the feed hopper. The sidewall of the hopper body 3-2 is provided with a plurality of first oblong through-holes 3-9 at positions corresponding to the star-shaped handles 3-8. These first oblong through-holes 3-9 are vertically defined, and the star-shaped handles 3-8 are threadedly connected to the first adjustment plate 3-52 through the first oblong through-holes 3-9. Releasing the star-shaped handles causes the second vertical plate to move up and down along the first oblong through-holes, thereby driving the second inclined plate away from or closer to the first inclined plate via the second vertical plate, thereby increasing or decreasing the width of the first material distribution channel.

[0049] The second material leveling assembly 3-6 includes a second fixed plate 3-61, a second adjustment plate 3-62, and a dispersion plate 3-63. The second fixed plate 3-61 is arranged on the inner wall of the bin body and is arranged along the length direction of the feed bin, and its two ends are arranged on the inner wall of the bin body. The second fixed plate 3-61 has an obtuse downward inclined plate, and the second adjustment plate 3-62 is vertically arranged in the bin body and arranged along the length direction of the feed bin, and its two ends are adjustably arranged on the inner wall of the bin body. The lower end of the second adjustment plate 3-62 cooperates with the upper surface of the inclined plate of the second fixed plate 3-61 to form a second material leveling channel; the dispersion plate 3-63 is arranged on the lower surface of the inclined plate of the second fixed plate 3-61, parallel to the hypotenuse and extending out of the hypotenuse, and its two ends are arranged on the inner wall of the bin body. The lower part of the dispersion plate is provided with a number of dispersion columns 3-64 along its length direction, and the dispersion columns 3-64 are arranged perpendicular to the material distribution plate 3-63.

[0050] The second adjustment plate 3-62 is adjustable at both ends on the inner wall of the hopper body to change the size of the second material-splitting channel. Specifically, the left and right outer sides of the hopper body 3-2 are respectively provided with a horizontal adjustment assembly, which can drive the second adjustment plate to move back and forth along the width direction of the feed hopper to change the size of the second material-splitting channel. The horizontal adjustment assembly includes a first baffle 3-10 and a horizontal screw 3-11, disposed on either side of the silo. Two sets of threaded sleeves 3-12 are disposed above and below the outer surface of the first baffle 3-10, with a vertical arm 3-13 disposed between the two sets of threaded sleeves 3-12. One end of the horizontal screw 3-11 is mounted on a fixed plate on one side of the silo, and the other end is threadedly connected to the vertical arm 3-13. Both ends of the second adjustment plate are fixed to a mounting plate 3-14. Two second oblong through-holes 3-15 are defined above and below the sidewall of the silo 3-2, corresponding to the mounting plate. These second oblong through-holes 3-15 are horizontally defined, and bolts pass through the threaded sleeves and second oblong through-holes of the first baffle and secure them to the mounting plate. Rotation of the horizontal screw causes the first baffle to move back and forth, which in turn drives the second adjustment plate, via the mounting plate, to move back and forth along the second oblong through-holes, approaching or moving away from the inclined plate of the second fixed plate, thereby reducing or increasing the width of the second material distribution channel.

[0051] The material flowing out of the first sparging channel enters between the second fixed plate and the second adjustment plate, and then flows out through the second sparging channel in thin layers. The first sparging channel can only ensure that the material flows down relatively flat, but cannot ensure the uniformity and flatness of the falling thin layer. The second sparging channel ensures that the material flows out as flatly and evenly as possible, thereby allowing the material to mix more evenly with the high-pressure water or superheated steam. After the material emerges from the second sparging channel in a thin layer, it will fall along the second fixed plate onto the dispersion plate. Under the action of the dispersion columns on the lower surface of the dispersion plate, a small amount of material flows out from the middle of the dispersion columns, while the majority of the material hits the dispersion columns and rises outward in a parabolic trajectory, increasing the dispersion of the material and allowing the thin layers of material on both sides to be better cross-mixed, thereby allowing the high-pressure water or superheated steam sprayed from the spray assembly to mix more evenly with the material.

[0052] In this embodiment, the spray assembly is designed as follows. The spray assembly includes a high-pressure pipe 3-16 disposed within the silo and a plurality of atomizing nozzles 3-17. The high-pressure pipe 3-16 is disposed between and parallel to the two second sparging assemblies. One end of the high-pressure pipe 3-16 extends through the silo to form an inlet, and the other end is sealed with a plug 3-18. A plurality of atomizing nozzles 3-17 are spaced apart within the silo, with the nozzles of the atomizing nozzles 3-17 facing downward. During operation, the high-pressure water pump station or high-pressure steam generator is activated and operated, and high-pressure water or high-pressure superheated steam enters the high-pressure pipe within the silo. The atomizing nozzles spray microscopic droplets of water or superheated steam toward the confluence of the two material waterfalls, thoroughly mixing the materials. Furthermore, first and second vertical adjustment assemblies are disposed on the left and right outer sides of the silo, respectively. These first and second vertical adjustment assemblies, disposed at either end of the high-pressure pipe, control the upward or downward movement of the high-pressure pipe. Since the high-pressure pipeline can be used without adjustment, it will not be described in detail.

[0053] To ensure that the incoming air is clean and free of dust and particulate matter, a filter device needs to be installed at the air inlet. Specifically, the top of the silo located between the two feed silos is concave to form a groove, and the air inlet is located at the bottom of the groove. A pull-out box body 3-19 is provided in the groove at the top of the silo, and the pull-out box body 3-19 is filled with filter cotton 3-20. The top opening of the pull-out box body facilitates air intake, and the bottom opening of the pull-out box body 3-19 facilitates air outlet. Air enters through the top opening of the pull-out box body, is filtered by the filter cotton, and then enters the silo through the bottom opening of the pull-out box body and the air inlet at the bottom of the groove.

[0054] In addition, a first material level sensor 3-21 is provided on at least one feed bin at the top of the bin body 3-2, and a second material level sensor 3-22 is provided on the hopper. Both the first material level sensor and the second material level sensor are paddle-rotation material level sensors.

[0055] When the system is installed and debugged, the feeding speed will be adjusted based on the falling speed of the material through the first and second sizing components and the speed of the negative pressure lifting material, so that the feeding and discharging are in a relatively balanced state, and there is basically no possibility of material accumulation.

[0056] However, when the material flows from three-way distributor A to three-way distributor B, the incoming material may increase instantly in some cases. At this time, the feed bin, the pipe between three-way distributor B and the feed bin, and even the three-way distributor B will be filled with materials. If the materials are not processed, they will only accumulate more and more. The first material level sensor is arranged on the upper part of the feed bin to detect whether there is material at this position. If there is material, it is assumed that a blockage has occurred. The control system alarms and issues instructions to control the three-way distributor A to move, so that the material passes through the three-way pipe and enters the detection screen; at the same time, the high-pressure water pump station or high-pressure steam generator is turned off to cut off the entry of high-pressure water or superheated steam. Wait for a certain period of time to allow the material remaining in the feed bin and above it to flow down. When the first material level sensor can no longer detect the material, the material amount in the feed bin is assumed to return to normal, and the relevant equipment can be started again. If the abnormality still occurs, turn off the negative pressure lifting system, close the air shutoff, and perform maintenance.

[0057] In addition, when the negative pressure lifting system fails, causing the lifting speed to slow down or stop, the water spray from the water mist nozzle causes the material to clump and stick to the inner wall of the hopper, which will cause the material to accumulate in the hopper. The second material level sensor is set in the hopper to detect whether there is a blockage in the hopper. When the material is blocked at the hopper outlet, the material level sensor will transmit a signal to the control system, which will alarm and issue a command to control the three-way distributor A to operate, allowing the material to enter the detection screen through the three-way pipe. At the same time, the high-pressure water pump station or high-pressure steam generator will be shut down to cut off the high-pressure water or superheated steam from entering. At the same time, the negative pressure lifting system will be shut down, the air shutoff will be closed, and the negative pressure lifting system will be repaired. At the same time, the discharge pipe will be removed to clear the material in the hopper.

[0058] In addition, the present invention also provides a method for using the powdery particulate matter moisture online regulation system, comprising the following steps:

[0059] (1) Obtain the moisture content of the powdered granular material and compare it with the standard moisture content. If it is equal to the standard moisture content, the powdered granular material passes through the three-way distributor A and the three-way pipe and enters the inspection screen; if it is less than or greater than the standard moisture content, the negative pressure feeding system is turned on, the air shutoff is turned on, the three-way distributor A is activated, the output end connected to the three-way pipe is closed, and the output end connected to the material homogenization bin feed port is opened. The powdered granular material passes through the three-way distributor B and is divided into two parts and enters the material homogenization bin;

[0060] For example, an automatic moisture detection system is used to periodically measure the moisture content of incoming powdered granules. This system is located on a device connected to the inspection screen. The system transmits the moisture content it obtains to the control system, which compares it with a programmed standard moisture value to determine whether the material should enter the online moisture adjustment system for moisture adjustment. Alternatively, the moisture content of incoming powdered granules can be manually measured periodically and the data input into the control system for comparison.

[0061] Under normal operating conditions, the powdery particles enter the inspection sieve by default through the three-way distributor A and the three-way pipe; the moisture content of the incoming material is obtained. If it is equal to the standard moisture content, the control system does not issue relevant instructions and the three-way distributor A does not operate. At this time, the powdery particles still enter the inspection sieve. If it is less than or greater than the standard moisture content, the control system issues an instruction to make the powdery particles enter the material homogenization bin.

[0062] If, during N comparisons, the powdered particles enter the material homogenizing bin, and during the subsequent N+1 comparisons, the moisture content of the powdered particles obtained equals the standard moisture content, three-way distributor A activates, closing the output end connected to the material homogenizing bin feed port and opening the output end connected to the three-way pipe. The powdered particles enter the inspection screen through the three-way pipe, the high-pressure water pump station or high-pressure steam generator stops, the negative pressure feed system shuts down, and the air shutoff device closes. Here, N is a positive integer greater than 0.

[0063] (2) The powdered particles enter the material homogenization bin, forming two cross material waterfalls, controlling the action of the high-pressure water pump station or high-pressure steam generator, and achieving humidification or drying through the spray assembly. The mixed powdered particles enter the Shakeron for gas-solid separation. The gas is filtered and discharged to the outside under the action of the negative pressure lifting system. The powdered particles flow out from the air shutoff at the lower end of the Shakeron and enter the inspection screen for screening.

[0064] For example, whether humidification or drying is achieved is determined by the moisture content of the product of the entire process. Due to the different moisture losses in different powder routes, the moisture content of the front, middle, and back routes and by-products varies greatly. Since this system is arranged at the front end of the detection screen, it does not change the original process route. Under the condition that the original process remains unchanged, the moisture content of the product obtained by this process is either equal to or lower than the standard moisture content, or equal to or higher than the standard moisture content. There is no situation where the moisture content of the product is sometimes lower than the standard moisture content and sometimes higher than the high-pressure standard moisture content. Therefore, according to the moisture content of the product obtained by this process, it is sufficient to selectively arrange a high-pressure water pump station or a high-pressure steam generator.

[0065] Specifically, the control of the high-pressure water pump station or high-pressure steam generator to achieve humidification or drying through the spray assembly includes:

[0066] When the source station is a high-pressure water pump station and the moisture content of the powdered particles is lower than the standard moisture content, the high-pressure water pump station will start, and high-pressure water will enter the high-pressure pipe in the material homogenization bin. The atomizing nozzle will spray the high-pressure water in the form of mist on the powdered particles and fully mix it with the powdered particles to achieve humidification.

[0067] Correspondingly, the moisture content of the product obtained by this process is equal to or lower than the standard moisture content. When the moisture online adjustment system is arranged in this process, a high-pressure water pump station needs to be equipped for selective humidification.

[0068] When the source station is a high-pressure steam generator and the moisture content of the incoming powdered particles is greater than the standard moisture content, the high-pressure steam generator will operate, and high-pressure superheated steam will enter the high-pressure pipe in the material homogenization bin. The atomizing nozzle will spray the high-pressure superheated steam onto the powdered particles and fully mix it with the powdered particles to achieve drying.

[0069] Correspondingly, the moisture content of the product obtained by this process is equal to or higher than the standard moisture content. When the moisture online adjustment system is arranged in this process, a high-pressure steam generator needs to be equipped for selective drying.

[0070] In addition, the method of use also includes:

[0071] Receive the material signal fed back by the first material level sensor. If the material signal indicates that there is material, it is determined that the material is blocked in the feed bin of the material homogenizing bin. At this time, an alarm is issued and a command is issued to control the action of the three-way distributor A, cut off the output end connected to the feed port of the material homogenizing bin, open the output end connected to the three-way pipe, and allow the material to enter the detection screen;

[0072] After a period of time, the material signal fed back by the first material level sensor is received again. If the material signal is no material, it is judged that the material is not blocked. At this time, the three-way distributor A is controlled to operate, the output end connected to the three-way pipe is cut off, and the output end connected to the material homogenization bin feed port is opened to allow the material to enter the material homogenization bin, and the system works normally. If the material signal is material, it is judged that the material is still blocked, and the high-pressure water pump station or high-pressure steam generator is closed, the negative pressure lifting system is closed, the air shutoff is closed, and maintenance is carried out.

[0073] For example, the first material level sensor periodically sends a material signal to the control system. If the signal received by the control system is that there is material, it is assumed that the material in the feed bin is blocked. The control system will sound an alarm and issue a command to control the three-way distributor A to operate, so that the material enters the detection screen through the three-way pipe, and the interruption is for a certain period of time. During this interval period, the material no longer enters the three-way distributor B of the material homogenizing bin. Under the action of the negative pressure lifting system, the accumulated material continues to fall and flow. When the signal fed back by the first material level sensor is that there is no material, the material amount in the feed bin is assumed to return to normal. At this time, the three-way distributor A is controlled to operate, cut off the output end connected to the three-way pipe, open the output end connected to the material homogenizing bin feed port, allow the material to enter the material homogenizing bin, and the system operates normally. If after a period of time, the signal fed back by the first material level sensor is still that there is material, it is assumed that the feed bin is still blocked. At this time, the high-pressure water pump station or high-pressure steam generator, the negative pressure lifting system, and the air shutoff should be closed. The specific cause should be analyzed and repaired.

[0074] Here, we only give one or two examples of reasons why the feed bin becomes clogged. The specific reasons should be analyzed based on the on-site situation. The reason for the feed bin blockage can be understood as the processing capacity of the material homogenizing bin is less than the feed capacity. For example, in some cases, the incoming material will increase instantly. At this time, the feed bin, the pipe between the three-way distributor B and the feed bin, and even the three-way distributor B will be filled with materials; the first material mixing channel and the first material mixing channel are narrow, and the material falls slowly in the homogenizing bin, which is less than the feed speed. The process of cleaning the material in the feed box is as follows: the staff arrives at the site, manually adjusts the position of the first adjustment plate and the second adjustment plate, increases the width of the first material mixing channel and the second material mixing channel, allows the material to enter the hopper, removes the discharge pipe, and discharges the clogged material.

[0075] Furthermore, the method of use also includes:

[0076] Receive the material signal fed back by the second material level sensor. If the material information indicates that there is material, it is determined that the material is blocked in the hopper of the material homogenizing bin. At this time, an alarm is issued and a command is issued to control the action of the three-way distributor A, cut off the output end connected to the material homogenizing bin feed port, open the output end connected to the three-way pipe, allow the material to enter the detection screen, and at the same time shut down the high-pressure water pump station or high-pressure steam generator, shut down the negative pressure lifting system, close the air lock, and carry out maintenance.

[0077] For example, the second material level sensor periodically sends a material signal to the control system. If the control system receives a signal indicating that there is material, it is assumed that the material in the hopper is blocked. If a blockage occurs, the control system will alarm and issue an instruction to control the action of the three-way distributor A, so that the material enters the detection screen through the three-way pipe, shut down the high-pressure water pump station or high-pressure steam generator, cut off the entry of high-pressure water or superheated steam, and at the same time shut down the negative pressure lifting system, close the air shutoff device, analyze the specific cause, and perform repairs.

[0078] Here, we only provide one or two examples of possible causes of hopper blockage. The specific cause should be analyzed based on the on-site situation. For example, a malfunction in the negative pressure feeding system can slow or stop the feeding process, causing material to accumulate in the hopper. Alternatively, a burst of water mist nozzles can stick flour and other particles in the powdered material to the hopper walls. As the accumulation increases, it can block the hopper or discharge pipe outlet, further increasing the amount of material in the hopper. To clear the hopper, personnel will visit the site, dismantle the discharge pipe, and remove the clogged material.

[0079] This cleverly designed system selectively utilises high-pressure water pumping stations or steam generators to humidify or dry materials according to the material moisture content of each process, improving quality and overall profitability. Furthermore, the system's electrical equipment and high-pressure water pumping stations or steam generators are always under control, enabling automatic, non-stop system adjustments.
