Description

Technical Field

[0001] The utility model relates to the technical field of material storage, in particular to a segregation-proof cloth storage system. Background Art

[0002] During the stacking process of large industrial material storage bins, due to uneven cloth feeding, the materials will be piled up in a conical shape in the storage bin (i.e., a material cone appears). The appearance of the material cone will cause the large particles in the stacking process to roll secondary along the inclined surface of the material cone and tend to move towards the bin wall. As a result, there are more large particles at the position tending to the bin wall and more small particles at the position tending to the center of the bin, thus resulting in the segregation phenomenon of the materials. This segregation phenomenon will reduce the quality of the materials in the storage bin and the economic benefits of the materials.

[0003] Currently, to solve the above segregation phenomenon, the commonly adopted measure is to decompose the original large material cone in the bin into multiple small material cones. In this way, the secondary rolling distance of the large particles along the diameter direction of the bin will be greatly reduced, thereby reducing the segregation phenomenon. Implementing the above measure usually involves changing the original single central feeding port into multiple feeding ports and feeding simultaneously. For example, the feeding structures disclosed in Chinese patents with publication numbers CN103538940A and CN 207404251U.

[0004] Although the above measure divides the large material cone into multiple small material cones, the material cone still exists. Although the secondary rolling distance of the large particles can be greatly reduced, there will still be secondary rolling, so the segregation phenomenon will still inevitably occur. In this regard, the applicant believes that it is necessary to further solve the phenomenon of secondary rolling of large particles to further avoid material segregation. Summary of the Utility Model

[0005] Aiming at the problem that even if the large material cone is divided into multiple small material cones during the stacking process as described in the above background art, there is still secondary rolling of large particles and the segregation phenomenon will still inevitably occur. The utility model provides a segregation-proof cloth feeding method and a segregation-proof cloth storage system to avoid the appearance of a material cone during stacking and further avoid the occurrence of the material segregation phenomenon.

[0006] The technical solution adopted by the utility model to solve its technical problems is: In the first aspect, the utility model provides a segregation-proof cloth feeding method. The cloth feeding method feeds materials into the bin through a cloth feeder arranged at the top of the bin. Among them, the materials discharged by the cloth feeder are thrown out from the side of the cloth feeder.

[0007] During the cloth feeding process, the cloth feeder rotates continuously around a vertical rotation center line. During the rotation process, by changing the rotation speed of the cloth feeder, the translation distance of the materials in the bin relative to the throwing point is gradually adjusted to make the materials spread layer by layer in the bin.

[0008] Preferably, in the above anti-segregation cloth laying method, during the process of laying materials layer by layer, each layer of materials is gradually laid from the inside to the outside or from the outside to the inside;

[0009] Among them, the rotation speed of the spreader is changed as follows: when laying materials gradually from the inside to the outside, the rotation speed of the spreader is gradually increased to gradually increase the translation distance of the materials in the silo relative to the throwing point until the falling point of the materials adheres to the side wall of the silo; when laying materials gradually from the outside to the inside, the rotation speed of the spreader is gradually decreased to gradually decrease the translation distance of the materials in the silo relative to the throwing point until the falling point of the materials is near the center of the silo.

[0010] In the above anti-segregation cloth laying method, the movement trajectory of the materials is as follows: since the materials discharged by the spreader are thrown from the side of the spreader, assuming that the spreader does not rotate, then after the materials are discharged from the spreader, their movement trajectory will be a parabolic motion. However, in the above method, the spreader rotates continuously during cloth laying. Therefore, the movement trajectory of the materials discharged from the spreader will be a rotating parabolic motion, that is, the materials will superimpose a rotational motion when making a parabolic motion.

[0011] Since the spreader rotates continuously during the cloth laying process, the rotation speed of the spreader determines the initial speed of the materials when they are discharged from the spreader, that is, the faster the rotation speed of the spreader, the greater the initial speed of the materials when they are discharged from the spreader, and vice versa. Based on this, only by changing the rotation speed of the spreader can the translation distance of the materials in the silo relative to the throwing point be adjusted by changing the initial speed of the materials. Therefore, during the cloth laying process, the materials can be gradually and smoothly laid from the inside to the outside or from the outside to the inside by changing the rotation speed of the spreader. And after each layer of materials is laid, the rotation speed of the spreader is changed in the opposite direction, and then the subsequent layer of materials can be gradually laid. For example, if the rotation speed of the spreader is gradually increased when laying the previous layer of materials, then when laying the subsequent layer of materials, the rotation speed of the spreader needs to be gradually decreased, and so on, so as to realize the layer-by-layer laying of the materials.

[0012] It can be seen that in the above anti-segregation cloth laying method, during the cloth laying process, the materials are laid layer by layer step by step, and each layer of materials is gradually and smoothly laid from the inside to the outside or from the outside to the inside. Therefore, the material cone mentioned in the background art will not appear, and further, the phenomenon of secondary rolling of large particles will not occur, thus avoiding the material segregation phenomenon caused by the secondary rolling of large particles.

[0013] Furthermore, during the cloth laying process, the maximum rotation speed of the spreader is determined by detecting the height of the materials already laid in the silo.

[0014] In a second aspect, the present utility model further provides a segregation-preventing cloth storage system, which includes:

[0015] A silo with a discharge opening provided at the bottom;

[0016] A cloth distributor provided at the top of the silo. The cloth distributor has a discharge opening through which materials are discharged from the side of the cloth distributor. The cloth distributor can rotate around a vertical rotation center line and the rotation speed is variable;

[0017] Wherein, during cloth distribution, the cloth distributor continuously rotates around the rotation center line. During the rotation process, the translation distance of the materials in the silo relative to the throwing point can be gradually adjusted by changing the rotation speed of the cloth distributor, so that the materials are laid layer by layer in the silo.

[0018] Preferably, in the above segregation-preventing cloth storage system, during the process of laying materials layer by layer, each layer of materials is gradually laid from the inside out or from the outside in;

[0019] Wherein, the rotation speed of the cloth distributor is changed in the following manner: when laying materials gradually from the inside out, the rotation speed of the cloth distributor is gradually increased to gradually increase the translation distance of the materials in the silo relative to the throwing point until the material dropping point adheres to the side wall of the silo; when laying materials gradually from the outside in, the rotation speed of the cloth distributor is gradually decreased to gradually decrease the translation distance of the materials in the silo relative to the throwing point until the material dropping point is near the center of the silo.

[0020] Further, a sensor for detecting the height of the materials in the silo is provided in the silo; during the cloth distribution process, the maximum rotation speed of the cloth distributor is determined based on the material height detected by the sensor.

[0021] Further, the number of the sensors is multiple, and the sensors are arranged in sequence from bottom to top along the inner side wall of the silo, and each sensor is respectively used to detect whether there are materials at the height where it is located.

[0022] The above segregation-preventing cloth storage system is a specific device designed based on the foregoing segregation-preventing cloth method. The operation mode and segregation-preventing principle during cloth distribution of the system can refer to the above segregation-preventing cloth method, which has been elaborated in detail in the above segregation-preventing cloth method, so it will not be repeated here.

[0023] Similarly to the aforementioned anti-segregation cloth feeding method, when the above anti-segregation cloth feeding and storage system works, materials enter through the feeding hopper of the cloth feeder and then are discharged from the discharging port of the cloth feeder. During the cloth feeding process, the cloth feeder rotates continuously and the rotation speed changes in the manner described above. Therefore, the materials discharged from the discharging port are gradually and smoothly laid layer by layer in the silo, so there is no situation of forming a material cone as described in the background art, and further, the phenomenon of secondary rolling of large particle materials is avoided, thus preventing the occurrence of material segregation phenomenon.

[0024] Furthermore, the above anti-segregation cloth feeding and storage system further includes a cyclone dust collector;

[0025] The cyclone dust collector has an air inlet pipe, a dust discharging port and a cylinder body; wherein, the air inlet pipe is communicated with the top of the silo, and the dust discharging port is communicated with the position at the top of the silo and close to the side wall of the silo. When the cyclone dust collector operates, the air inlet pipe can suck small particle materials suspended in the space at the top of the silo into the cylinder body, and then after cyclone separation in the cylinder body, the materials are discharged from the dust discharging port.

[0026] In the above technical solution, the cyclone dust collector plays a role in translating small particle materials. After the small particle materials suspended in the space at the top of the silo are sucked into the air inlet pipe, they are cyclone separated in the cylinder body and then discharged from the dust discharging port, so that the translation distance of such small particle materials is increased, and they can cover the vicinity of the side wall of the silo, thus improving the situation that there are obvious differences between the central area of the silo and the materials near the side wall of the silo, and increasing the proportion of small particle materials near the side wall of the silo, thereby further solving the problem of possible material segregation during the cloth feeding process.

[0027] Furthermore, the cyclone dust collector further has an exhaust pipe; the exhaust port of the exhaust pipe is arranged in cooperation with the discharging port of the cloth feeder and can jet gas from near the discharging port towards the side wall of the silo to provide power to assist the small particle materials to increase their translation distance.

[0028] In the above technical solution, the dust removal gas discharged during the operation of the cyclone dust collector is ingeniously and reasonably utilized. The dust removal gas is guided to the vicinity of the discharging port of the cloth feeder to provide power to assist the small particle materials to increase their translation distance, and further ensure that the small particle materials can cover the vicinity of the side wall of the silo, increasing the proportion of small particle materials near the side wall of the silo, and further avoiding the generation of segregation phenomenon.

[0029] Preferably, the exhaust port of the exhaust pipe is arranged above or below the rotation plane of the discharging port; when the cyclone dust collector operates, the exhaust port jets gas towards the side wall of the silo to assist the small particle materials released from the discharging port to increase their translation distance.

[0030] Alternatively, preferably, the exhaust pipe is inserted through the distributor, and the exhaust port of the exhaust pipe is located below the rotation plane of the discharge port, and the exhaust port can rotate synchronously with the discharge port; when the cyclone dust collector operates, the exhaust port jets gas towards the side wall of the silo to assist the small particle materials released from the discharge port to increase their translation distance.

[0031] Furthermore, a part of the wall of the exhaust pipe is composed of a sieve mesh, and the sieve mesh is located in the distributor, which can screen the small particle materials in the distributor to enter the exhaust pipe and be ejected from the exhaust port along with the gas in the exhaust pipe.

[0032] Or, preferably, the cyclone dust collector further has an exhaust pipe; the exhaust port of the exhaust pipe is connected to the distributor; when the cyclone dust collector operates, the exhaust port mixes high-pressure gas into the distributor, and uses the high-pressure gas to assist the small particle materials to increase their translation distance when being discharged from the discharge port.

[0033] Furthermore, the distance that the gas discharged from the exhaust port assists the small particle materials to translate changes in a positive correlation with the rotation speed of the distributor.

[0034] In addition, the above anti-segregation cloth storage system may not be provided with a cyclone dust collector, but instead a single exhaust pipe is introduced; the exhaust port of the exhaust pipe is arranged in cooperation with the discharge port of the distributor, and can jet gas from near the discharge port towards the side wall of the silo to provide power to assist the small particle materials to increase their translation distance.

[0035] Preferably, the exhaust port of the exhaust pipe is located below the discharge port; the distance that the gas discharged from the exhaust port assists the small particle materials to translate changes in a positive correlation with the rotation speed of the distributor.

[0047] The present utility model will be further introduced in detail below in conjunction with specific embodiments, but the implementation manners of the present utility model are not limited thereto

[0048] The present utility model provides an anti-segregation cloth method. In this cloth method, the cloth distributor arranged at the top of the silo is used to distribute cloth into the silo. Among them, the material discharged by the cloth distributor is thrown from the side of the cloth distributor. The ejection angle of the throw can be tangent to the horizontal plane, or can be inclined upward at a certain angle relative to the horizontal plane, or can also be inclined downward at a certain angle relative to the horizontal plane

[0049] During the cloth distribution process of the above cloth method, the cloth distributor will continuously rotate around a vertical rotation center line. During the rotation process, the translation distance of the material in the silo relative to the throwing point can be gradually adjusted by changing the rotation speed of the cloth distributor, so that the material is laid layer by layer in the silo

[0050] Preferably, during the process of laying materials layer by layer, each layer of materials is laid gradually from the inside out or from the outside in. Among them, the rotation speed of the distributor is changed in the following manner: when laying materials gradually from the inside out, the rotation speed of the distributor is gradually increased to gradually increase the translation distance of the materials in the silo relative to the throwing point until the falling point of the materials adheres to the side wall of the silo; when laying materials gradually from the outside in, the rotation speed of the distributor is gradually decreased to gradually decrease the translation distance of the materials in the silo relative to the throwing point until the falling point of the materials is near the center of the silo.

[0051] The above-mentioned translation distance refers to the horizontal distance between the material falling point and its throwing point.

[0052] In the above anti-segregation feeding method, the movement trajectory of the materials is as follows: since the materials discharged by the distributor are thrown from the side of the distributor, assuming that the distributor does not rotate, then after the materials are discharged from the distributor, their movement trajectory will be a parabolic motion. However, in the above method, the distributor rotates continuously during feeding, so the movement trajectory of the materials discharged from the distributor will be a rotating parabolic motion, that is, the materials will superimpose a rotational motion when making a parabolic motion.

[0053] Since the distributor rotates continuously during the feeding process, the rotation speed of the distributor determines the initial speed of the materials when they are discharged from the distributor. That is, the faster the rotation speed of the distributor, the greater the initial speed of the materials when they are discharged from the distributor, and vice versa. Based on this, only by changing the rotation speed of the distributor can the initial speed of the materials be changed, and then the translation distance of the materials in the silo relative to the throwing point can be adjusted. Therefore, during the feeding process, the rotation speed of the distributor can be changed continuously or intermittently to make the materials gradually and smoothly laid from the inside out or from the outside in. And after laying each layer of materials, the rotation speed of the distributor is changed in the reverse direction, and then the subsequent layer of materials can be gradually laid. For example, when laying the previous layer of materials, the rotation speed of the distributor gradually increases, then when laying the subsequent layer of materials, the rotation speed of the distributor needs to gradually decrease, and so on, so as to realize the layer-by-layer laying of the materials.

[0054] It can be seen that in the above anti-segregation feeding method during the feeding process, the materials are laid layer by layer gradually, and each layer of materials is gradually and smoothly laid from the inside out or from the outside in. Therefore, there will be no material cone as mentioned in the background technology, and thus there will be no phenomenon of secondary rolling of large particles, thereby avoiding the material segregation phenomenon caused by the secondary rolling of large particles.

[0055] Among them, the difference between continuously changing the rotation speed of the distributor and intermittently changing the rotation speed of the distributor is as follows:

[0056] Continuously changing the rotation speed of the spreader means that the rotation speed of the spreader changes steplessly (i.e., the speed changes continuously). At this time, when laying a layer of material, the landing point of the material will move gradually in a spiral shape from the inside to the outside or from the outside to the inside. Refer to Figure 1 , in the figure, two moving trajectories of the landing point of the material in this case are shown, which are laying the material by gradually moving from the inside to the outside in a spiral shape and laying the material by gradually moving from the outside to the inside in a spiral shape;

[0057] Intermittently changing the rotation speed of the spreader means that the rotation speed of the spreader increases or decreases intermittently. At this time, when laying a layer of material, it is laid ring by ring. In each ring, the rotation speed of the spreader remains constant. After laying one ring, the rotation speed of the spreader increases or decreases appropriately, and then the next ring is laid, and so on; that is, at this time, the landing point of the material moves step by step from the inside to the outside or from the outside to the inside ring by ring. Refer to Figure 2 , in the figure, two moving trajectories of the landing point of the material in this case are shown, which are laying the material with the landing point of the material moving step by step from the inside to the outside ring by ring and laying the material with the landing point of the material moving step by step from the outside to the inside ring by ring. The numbers in the figure represent the laying sequence of each ring, and the smaller the number, the earlier it is laid. The arrows in the figure represent the moving direction of the landing point of the material when laying each ring. Of course, it is also possible that the moving direction of the landing point of the material is opposite to the direction of the arrows in the figure.

[0058] In some embodiments, when spreading the material, the maximum rotation speed of the spreader can be determined by detecting the height of the material already laid in the silo. Preferably, when detecting the height of the material already laid in the silo, it can be detected by a sensor provided on the inner side wall of the silo. For example, a plurality of pressure sensors are provided on the inner side wall of the silo, and the pressure sensors are arranged at intervals of a certain distance from bottom to top in sequence. When the material in the silo accumulates to the position where a certain sensor is located, the sensor will be triggered due to the pressure exerted by the material on it, and then transmit a signal to the background system, so that the background system knows the height of the material in the silo at this time. Of course, the sensor may not be a pressure sensor, but other types of sensors suitable for this scenario.

[0059] The maximum rotation speed of the distributor is determined by detecting the height of the material already laid in the silo. The purpose is as follows: Since the movement trajectory of the material after it is discharged from the distributor is a rotational parabolic motion, that is, it includes a parabolic motion. During the parabolic motion, the movement trajectory of the material is an arc motion. The greater the height difference of this arc motion, the farther the translation distance. Therefore, when the height of the material accumulated in the silo is relatively low, the height difference of the material is large, and the maximum rotation speed of the distributor does not need to be too large, and the material can still fall near the side wall of the silo. However, as the material in the silo gradually piles up, the height difference of the material will correspondingly decrease. At this time, if the maximum rotation speed of the distributor is still the same as before, then the material will not be able to fall near the side wall of the silo. Therefore, it means that at this time, the maximum rotation speed of the distributor needs to be increased to ensure that the material can fall near the side wall of the silo. So during the operation of the distributor, the maximum rotation speed of the distributor can be determined by detecting the height of the material already laid in the silo to ensure that the material can reach near the side wall of the silo when laying each layer of material.

[0060] Based on the above anti-segregation batching method, the present application provides the following specific embodiments.

[0061] Embodiment 1:

[0062] Refer to Figure 3 , this embodiment provides an anti-segregation batching storage system, which includes a silo 100 and a distributor 200.

[0063] A discharge port 110 is provided at the bottom of the silo 100. Among them, the present utility model does not limit the number of the discharge ports 110 provided at the bottom of the silo 100, and it can be one or more. For example, as Figure 3 shown, the discharge ports 110 shown in the figure are arranged in multiple rows, and three discharge ports 110 are provided in each row. When discharging, the loading vehicle can stop below the discharge port 110 to receive the material.

[0064] The distributor 200 is provided at the top of the silo 100. Refer to Figure 4 , the distributor 200 includes a riser 210, a discharge pipe 220 and a feed hopper 230. The discharge pipe 220 is connected to the bottom of the riser 210 and is inclined at a certain angle relative to the riser 210, and the discharge pipe 220 is usually an arc-shaped structure. The end of the discharge pipe 220 away from the riser 210 is the discharge port 221, and the material is discharged from the side of the distributor 200 through this discharge port 221. The feed hopper 230 is provided above the riser 210. Among them, the number of the discharge pipes 220 can be one, or multiple and evenly distributed. For example, as Figure 4As shown, the number of the discharging pipes 220 is four, and the discharging pipes 220 are evenly distributed around the vertical pipe 210 at equal intervals. The distributor 200 can be driven by a motor 240 through transmission mechanisms such as a belt 250 and belt pulleys to rotate around a vertical rotation center line a, and the rotation speed during the rotation process can be changed.

[0065] Among them, during the cloth feeding, the distributor 200 rotates continuously around the rotation center line a. During the rotation process, the translation distance of the material relative to the throwing point in the bin 100 can be gradually adjusted by changing the rotation speed of the distributor 200, so that the material is laid layer by layer in the bin 100.

[0066] Preferably, during the process of laying the material layer by layer, each layer of the material is gradually laid from the inside to the outside or from the outside to the inside. Among them, the change of the rotation speed of the distributor 200 is carried out in the following manner: when the material is gradually laid from the inside to the outside, the rotation speed of the distributor 200 is gradually increased to gradually increase the translation distance of the material relative to the throwing point in the bin 100 until the material falling point adheres to the side wall of the bin 100; when the material is gradually laid from the outside to the inside, the rotation speed of the distributor 200 is gradually decreased to gradually decrease the translation distance of the material relative to the throwing point in the bin 100 until the material falling point is near the center of the bin 100.

[0067] Consistent with the above anti-segregation cloth feeding method principle, in order to ensure that the material can reach near the side wall of the bin when laying each layer of the material, in this embodiment, a sensor 300 for detecting the height of the material in the bin 100 is provided in the bin 100. During the cloth feeding process, the maximum rotation speed of the distributor 200 is determined according to the material height detected by the sensor 300.

[0068] Preferably, the number of the sensors 300 is multiple, and the sensors 300 are arranged in sequence from bottom to top along the inner side wall of the bin 100. Each sensor 300 is respectively used to detect whether there is material at the height where it is located. The sensor 300 is a pressure sensor or other types of sensors applicable to this scenario.

[0069] The anti-segregation cloth feeding and storage system of this embodiment is a specific device designed based on the above anti-segregation cloth feeding method. The operation mode and anti-segregation principle during the cloth feeding in this embodiment can refer to the above anti-segregation cloth feeding method, which has been elaborated in detail in the above anti-segregation cloth feeding method, so this embodiment will not be repeated here.

[0070] Similarly to the above anti-segregation cloth method, when the anti-segregation cloth storage system of this embodiment works, the material enters from the feed hopper 230 of the spreader 200 and then is discharged from the discharge port 221 of the spreader 200. During the cloth spreading process, the spreader 200 rotates continuously and the rotation speed changes in the manner described above. Therefore, the material discharged from the discharge port 221 is gradually and gently laid layer by layer in the silo 100. So, there is no situation of forming a material cone as described in the background art, and further, there will be no phenomenon of secondary rolling of large particle materials, thus avoiding the material segregation phenomenon caused by the secondary rolling of large particle materials.

[0071] Application example effect of the above anti-segregation cloth storage system:

[0072] At present, serious segregation phenomena occur during the production of manufactured sand by major domestic mines, and segregation phenomena occur during the production of 10 - 25 mm or 16 - 25 mm stones. For example, the 16 - 25 mm stones are divided into 16 - 19 mm stones and 20 - 25 mm stones in the grading. During storage, the 20 - 25 mm stones tend to be distributed around the silo. After using the above anti-segregation cloth storage system of the present utility model, the above segregation phenomenon can be significantly improved.

[0073] However, it should be noted that although the material segregation phenomenon caused by the secondary rolling of large particle materials is eliminated during the operation of the above Embodiment 1, the following problems may still exist:

[0074] If the material contains a certain proportion of small particle materials with relatively small particle sizes (greatly affected by wind force), then after the material is thrown out from the discharge port 221, during the entire rotational parabolic motion process, the small particle materials and the large particle materials are affected by air resistance, and the motion trajectories may be significantly different; that is, among the materials thrown out at the same time, the large particle materials may have a relatively longer translation distance, and the small particle materials are significantly affected by air resistance and may have a relatively shorter translation distance. Even a large amount of small particle materials will form dust and float in the top space of the silo; therefore, that is to say, it is difficult for a large amount of small particle materials to cover the vicinity of the silo sidewall in terms of translation distance. Eventually, there will be an obvious difference between the materials in the area near the center of the silo and the materials in the area near the silo sidewall. In the area near the center of the silo, the proportion of small particle materials is relatively high, and in the area near the silo sidewall, the proportion of small particle materials is relatively low; so, during the cloth spreading process of the anti-segregation cloth storage system of Embodiment 1, there may still be a certain degree of segregation.

[0075] In response to this, the applicant made further improvements on the basis of Embodiment 1 to solve the above problems. For the specific improvement solutions, please refer to the following Embodiment 2 to Embodiment 5.

[0076] Embodiment 2:

[0077] See Figure 5 and Figure 6 In this embodiment, a cyclone dust collector 400 is additionally provided on the basis of Embodiment 1. The cyclone dust collector 400 is installed on the top of the silo 100 and has an air inlet pipe 410, a dust discharge port 420, and a cylinder body 430. Among them, the air inlet pipe 410 communicates with the top of the silo 100, and the dust discharge port 420 communicates with the top of the silo 100 and a position close to the side wall of the silo 100. When the cyclone dust collector 400 operates, the air inlet pipe 410 can suck small particle materials suspended in the space at the top of the silo 100 into the cylinder body 430, and then after cyclone separation by the cylinder body 430, the materials are discharged from the dust discharge port 420.

[0078] Among them, the cyclone dust collector 400 can adopt a conventional cyclone dust collector on the current market, and the number thereof can be multiple. In this embodiment, the number of cyclone dust collectors 400 is preferably four, and the four cyclone dust collectors 400 are respectively distributed at the front, rear, left, and right positions on the top of the silo 100.

[0079] Among them, the connection point of the air inlet pipe 410 and the top of the silo 100 is not particularly limited. It can be connected to a position slightly in the middle of the top of the silo 100 or a position slightly on the side of the top of the silo 100. This is because during the cloth feeding process, a large amount of small particle materials will float in the space at the top of the silo 100, and their concentration is relatively high. Therefore, setting the above connection point at any appropriate position can achieve the same material absorption effect.

[0080] During the cloth feeding process of the cloth feeder 200, a large amount of small particle materials may form dust and float in the space at the top of the silo 100, and the concentration is relatively high. At this time, start the cyclone dust collector 400. The air inlet pipe 410 of the cyclone dust collector 400 will form a negative pressure, suck the small particle materials floating on the top of the silo 100 into the air inlet pipe 410, and then after cyclone separation by the cylinder body 430 of the cyclone dust collector 400, the above materials will be discharged from the dust discharge port 420. Since the dust discharge port 420 is arranged at a position close to the side wall of the silo 100, the materials discharged from the dust discharge port 420 will be dispersed and gradually fall to a position close to the side wall of the silo 100 under the action of gravity. It can be seen that in this embodiment, the cyclone dust collector 400 plays a role in translating small particle materials, increasing their translation distance, enabling them to cover the vicinity of the side wall of the silo, thereby improving the situation where there are obvious differences in materials between the central area of the silo and the vicinity of the side wall of the silo, increasing the proportion of small particle materials near the side wall of the silo, and further solving the problem of possible segregation of materials during the cloth feeding process.

[0081] In order to further solve the problem that it is difficult for the above-mentioned translated small particle materials to cover the vicinity of the side wall of the silo, in some embodiments, the following further improvements can be made:

[0082] See Figure 6 , the cyclone dust collector 400 further has an exhaust pipe 440, and the exhaust port 441 of the exhaust pipe 440 is arranged in cooperation with the discharge port 221 of the distributor 200, and can jet gas from near the discharge port 221 to the side wall of the silo 100 to provide power assistance to small particle materials to increase their translation distance.

[0083] More specifically, the exhaust port 441 of the exhaust pipe 440 is arranged above or below the rotation plane of the discharge port 221. When the cyclone dust collector 400 operates, the exhaust port 441 jets gas towards the side wall of the silo 100 to assist the small particle materials released from the discharge port 221 to increase their translation distance.

[0084] Wherein, the rotation plane of the discharge port 221 mentioned above refers to: the plane enclosed by the path passed by the discharge port 221 during the rotation of the distributor 200 around the rotation center line a.

[0085] Whether the exhaust port 441 is arranged above or below the rotation plane of the discharge port 221 can achieve the purpose of assisting small particle materials to increase their translation distance. Among them, Figure 6 What is shown is that the exhaust port 441 is arranged above the rotation plane of the discharge port 221.

[0086] In the above technical solution, the dust removal gas discharged during the operation of the cyclone dust collector 400 is utilized skillfully and reasonably. Instead of wasting this part of the dust removal gas, it is skillfully guided to the vicinity of the discharge port 221 of the distributor 200 to provide power to assist small particle materials to increase their translation distance.

[0087] In this embodiment, a jet ejector 510 can be connected to the end of the exhaust port 441 to increase the flow rate of the discharged gas so that it is ejected in a high-pressure form. Preferably, see Figure 7 , three jet ejectors 510 with different ejection angles can be connected to the end of the exhaust port 441 to increase the coverage area of the airflow. Among them, the high-pressure airflow provided by the jet ejector 510 is more conducive to helping small particle materials overcome air resistance and increase their translation distance.

[0088] Preferably, see Figure 6 , a high-pressure sprayer 520 can also be installed at the front end of the jet ejector 510. The high-pressure sprayer 520 generates atomized gas with a certain humidity in the exhaust pipe 440 at the front end of the jet ejector 510. After the atomized gas is ejected by the jet ejector 510, its water molecules can combine with the small particle materials at the top of the silo 100, and part of the small particle materials can be wrapped on the surface of the materials with larger particle sizes, so that they can move along with the materials with larger particle sizes, and thus obtain a greater translation distance.

[0089] Preferably, referring to Figure 6 , a negative pressure port 511 can also be provided at the bottom of the ejector 510. During jetting, the rapid flow of gas generates negative pressure, and some small particle materials discharged from the discharge port 221 will enter the ejector 510 through the negative pressure port 511, and then be ejected with the airflow. Among them, the small particle materials entering the ejector 510 can be mixed with the water molecules in the airflow and then ejected to obtain a greater translation distance.

[0090] In this embodiment, the exhaust port 441 is fixedly arranged and does not rotate with the discharge port 221. During operation, since the exhaust ports 441 of the four cyclone dust collectors 400 are respectively located around the distributor 200, and the end of each exhaust port 441 is connected to three ejectors 510 with different ejection angles, the area that the ejector 510 can cover is relatively wide. During the rotation of the discharge port 221, most of the discharged materials will be within the influence range of the ejector 510. Therefore, a large amount of small particle materials will be affected by the ejector 510 and increase their translation distance, and finally this part of the small particle materials can cover near the side wall of the silo, further increasing the proportion of small particle materials near the side wall of the silo, thereby further solving the problem of possible segregation of materials during the feeding process.

[0091] Of course, it should be noted that: the above arrangement of the exhaust port 441 of the exhaust pipe 440 of the cyclone dust collector 400 in cooperation with the discharge port 221 of the distributor 200 (which can jet gas from near the discharge port 221 towards the side wall of the silo 100 to provide power to assist small particle materials to increase their translation distance) belongs to a preferred implementation manner. That is to say, in the process of specific implementation and application of the anti-segregation feeding and storage system of this embodiment, there are at least two setting methods: (1) setting the cyclone dust collector 400, only using the intake pipe 410 of the cyclone dust collector 400 to suck in small particle materials, and then after cyclone separation, discharging the small particle materials to a position near the side wall of the silo 100 through the ash discharge port 420; (2) on the basis of the first setting method, arranging the exhaust port 441 of the exhaust pipe 440 of the cyclone dust collector 400 in cooperation with the discharge port 221 of the distributor 200, and being able to jet gas from near the discharge port 221 towards the side wall of the silo 100 to provide power to assist small particle materials to increase their translation distance.

[0092] Embodiment 3:

[0093] This embodiment belongs to a replacement design for the positional relationship between the exhaust pipe 440 and the distributor 200 in Embodiment 2, specifically as follows:

[0094] Referring to Figure 8, in this embodiment, the exhaust pipe 440 enters the distributor 200 from one side of the distributor 200, coaxially penetrates through the riser 210 of the distributor 200, and the exhaust pipe 440 extends out from below the riser 210. The exhaust port 441 is located below the rotation plane of the discharge port 221, and the exhaust port 441 can rotate synchronously with the discharge port 221. Among them, the upper half of the distributor 200 is fixed, and the lower half can rotate driven by a transmission mechanism such as a motor 240, a belt 250, and a pulley. The exhaust pipe 440 extends into the distributor 200 from the upper half of the distributor 200. The pipe body above the exhaust port 441 is connected to the bottom of the riser 210 of the distributor 200 and is also hermetically connected to the exhaust pipe 440 in the distributor 200. Therefore, the exhaust port 441 can rotate synchronously with the lower half of the distributor 200 and can also ensure the real-time discharge of air flow.

[0095] When the cyclone dust collector 400 operates, the exhaust port 441 injects gas towards the side wall of the silo 100 to assist the small particle material released from the discharge port 221 to increase its translation distance.

[0096] Among them, an axial balance compensator 600 is provided on the pipe body above the exhaust port 441 and is connected to the riser 210. When the distributor 200 rotates, since the center of gravity will deviate from the axis and cause imbalance, the axial balance compensator 600 is added to balance this phenomenon. Among them, the setting of the axial balance compensator 600 belongs to a conventional technical means.

[0097] In this embodiment, the discharge port 221 is located above, and the exhaust port 441 is located below. When the two rotate synchronously, materials and air flow are discharged respectively. The air flow can act on the small particle materials in real time to increase their translation distance.

[0098] Similarly, this embodiment can also refer to Embodiment 2 and set the corresponding ejector 510 and high-pressure sprayer 520.

[0099] Embodiment 4:

[0100] Based on Embodiment 3, corresponding changes are made to the exhaust pipe 440 in this embodiment, which are specifically as follows:

[0101] See Figure 9 , in this embodiment, a section of the wall body of the part where the exhaust pipe 440 penetrates through the riser 210 of the distributor 200 is formed by enclosing a screen 442. That is, the screen 442 is located in the distributor 200, so it can screen the small particle materials in the distributor 200 to make them enter the exhaust pipe 440, and then be discharged from the exhaust port 441 along with the high-pressure gas in the exhaust pipe 440.

[0102] Preferably, the aperture of the mesh holes of the screen 442 is approximately 1 mm.

[0103] During operation, there is material passing through the distributor 200 and high-pressure gas passing through the exhaust pipe 440. When the high-pressure gas passes through the screen 442, the negative pressure generated by the high-speed movement of the gas flow will suck the small-particle material with a particle size less than 1 mm in the distributor into the screen 442, and then move with the gas flow and be discharged from the exhaust port 441 of the exhaust pipe 440.

[0104] The function of the above-mentioned screen 442 is similar to that of the negative pressure port 511 of the ejector 510 in Embodiment 2, both of which are to suck the small-particle material into the gas flow and then eject it with the gas flow to obtain a greater translation distance.

[0105] Among them, Figure 10 FIG. is a three-dimensional structural diagram of a preferred embodiment of the cooperation relationship between the exhaust pipe 440 and the distributor 200 in Embodiment 3 and Embodiment 4. In the figure, the exhaust pipe 440 enters the distributor 200 from the feed hopper 230 at the top of the distributor 200, then coaxially penetrates the riser 210 of the distributor 200, and extends out from below the riser 210.

[0106] The above-mentioned Embodiments 2 to 4 show several structural forms in which the exhaust port 441 of the cyclone dust collector 400 is arranged in cooperation with the discharge port 221 of the distributor 200. Each structural form can play a role in assisting the small-particle material to increase its translation distance. In actual use, the structural form with better effect and better control of the translation distance of the small-particle material can be selected according to the characteristics of the material and the test results. Of course, the structural forms in which the exhaust port 441 is arranged in cooperation with the discharge port 221 of the distributor 200 in the above several embodiments are not exhaustive, and other structural forms with similar working principles that can be conceived by those skilled in the art should also be included within the protection scope of the present invention.

[0107] Embodiment 5:

[0108] This embodiment also belongs to the replacement design of the positional relationship between the exhaust pipe 440 and the distributor 200 in Embodiment 2, specifically as follows:

[0109] See Figure 11 , in this embodiment, the exhaust port 441 is directly connected to the riser 210 of the distributor 200, and the connection position is the non-rotating part of the distributor 200, that is, the lower half of the distributor 200 can be driven to rotate by transmission mechanisms such as the motor 240, the belt 250, and the belt pulley, while the upper half is fixed and immovable, and the exhaust port 441 is connected to the upper half of the distributor 200.

[0110] When the cyclone dust collector 400 is operating, the exhaust port 441 mixes high-pressure gas into the distributor 200, and the high-pressure gas is used to assist small-particle materials to increase the translation distance when they are discharged from the discharge port 221.

[0111] When the material enters the riser 210 of the distributor 200 from the hopper 230 of the distributor 200, the density of the material is relatively loose and there are many gaps. At this time, if high-pressure gas is directly mixed into the material, the mixed high-pressure gas can move along with the material, and when it is discharged from the discharge port 221 later, the high-pressure gas can assist the small-particle materials to increase their translation distance.

[0112] It should be noted that in this embodiment, humidified gas (such as the atomized gas in Embodiment 2) cannot be mixed into the exhaust pipe 440 to avoid the material in the distributor 200 from caking and causing the distributor 200 to be blocked.

[0113] In addition, in the above Embodiments 2 to 5, a receiving hopper (not shown in the figure) can be provided below the ash discharge port 420 of the cyclone dust collector 400. The receiving hopper can receive the material released from the ash discharge port 420 and also release the received material. The purpose of setting the receiving hopper is as follows:

[0114] After the cloth feeding is completed, although the distributor 200 stops releasing the material, the small-particle materials that previously floated on the top of the silo 100 still exist and will not disappear immediately. If these small-particle materials are not processed, after standing for a period of time, these small-particle materials will settle and accumulate on the surface layer of the material in the silo, thereby affecting the uniformity of the particle size of the material in the silo. Especially when cloth feeding next time, these small-particle materials will be sandwiched between the materials of the two cloth feedings, resulting in defects in the quality of the material during feeding. To this end, the above receiving hopper is specially added. After the cloth feeding is completed, the receiving hopper is moved to below the ash discharge port 420, and then the cyclone dust collector 400 is allowed to continue working for a period of time to suck away the small-particle materials floating on the top of the silo 100 and discharge them into the receiving hopper, so as to prevent these small-particle materials from spreading on the surface layer of the material in the silo and affecting the material quality. After that, when cloth feeding next time, the receiving hopper is allowed to gradually release the above small-particle materials, so as to ensure that the above small-particle materials can be gradually mixed into the materials of the next cloth feeding without affecting the material quality.

[0115] Preferably, in the above Embodiments 2 to 5, the distance by which the gas discharged from the exhaust port 441 assists the small-particle materials to translate changes positively with the rotation speed of the distributor.

[0116] Since the translation distance of small particulate materials assisted by gas is mainly affected by parameters such as air volume, air pressure, and wind speed, the greater the air volume, air pressure, and wind speed, the farther the translation distance; conversely, the smaller the translation distance. Therefore, during specific settings, the translation distance of small particulate materials assisted by gas can be adjusted by changing the magnitudes of the three parameters of air volume, air pressure, and wind speed of the gas discharged from the exhaust port 441, so that it changes positively with the rotation speed of the distributor. That is, the faster the rotation speed of the distributor, the greater the air volume, air pressure, and wind speed of the gas discharged from the exhaust port 441, and the farther the translation distance of the small particulate materials; conversely, the slower the rotation speed of the distributor, the smaller the air volume, air pressure, and wind speed of the gas discharged from the exhaust port 441, and the closer the translation distance of the small particulate materials.

[0117] Specifically, especially in Embodiment 3, since the material and the air flow are ejected separately, with the material on top and the air flow below, during operation, the translation distance of large particulate materials is farther, and the translation distance of small particulate materials is closer. Therefore, the air flow mainly blows on the small particulate materials. During the cloth laying process, the rotation speed of the distributor is changing, and the translation distance of the large particulate materials changes accordingly. Therefore, the relationship between the air flow and the rotation speed of the distributor is preferably satisfied as follows: when the rotation speed of the distributor gradually increases, at this time the translation distance of the large particulate materials gradually becomes larger, so the air volume, air pressure, and wind speed of the air flow should also gradually increase, so as to enable the small particulate materials to gradually increase the translation distance and always be equivalent to the translation distance of the large particulate materials; conversely, when the rotation speed of the distributor gradually decreases, at this time the translation distance of the large particulate materials gradually becomes smaller, so the air volume, air pressure, and wind speed of the air flow should also gradually decrease, so as to enable the small particulate materials to gradually decrease the translation distance and always be equivalent to the translation distance of the large particulate materials.

[0118] For the above-mentioned Embodiment 3, since the material and the air flow are ejected separately, and the material is on the upper side and the air flow is on the lower side, during operation, the air flow mainly blows on the small particle materials and less on the large particle materials. Therefore, it is relatively easy to control the "air volume, air pressure, and wind speed" according to the "change of the rotating speed of the distributor" during the process, so as to achieve the purpose that the "translation distance of the small particle materials" changes dynamically with the "translation distance of the large particle materials" and the two are always roughly the same. For Embodiment 4, relatively few small particle materials are sucked into the exhaust pipe 440. Therefore, it also basically meets the conditions of "the material and the air flow are ejected separately" and "the material is on the upper side and the air flow is on the lower side". So, it is also relatively easy to achieve the purpose that the "translation distance of the small particle materials" changes dynamically with the "translation distance of the large particle materials" and the two are always roughly the same by controlling the relationship between the "air volume, air pressure, wind speed" and the "rotating speed of the distributor". For the implementation scheme in other Embodiment 2 where the air flow is above the material and the implementation scheme in Embodiment 5 where the air flow is mixed into the material, it is usually not easy to achieve the above purpose by controlling the relationship between the "air volume, air pressure, wind speed" and the "rotating speed of the distributor".

[0119] In the above-mentioned Embodiments 2 to 5, since the cyclone dust collector 400 is introduced, the following advantages are also provided: Generally, in a closed space, when there is sufficient oxygen and the dust concentration is too high (such as greater than 50 g / m 3 ) and the dust is in a floating state, at this time, if there is a fire source (such as an electric spark, a frictional spark), dust explosion is extremely likely to occur; while the introduction of the cyclone dust collector 400 can effectively reduce the dust concentration in the top space of the silo 100, thereby eliminating the possibility of dust explosion.

[0120] Embodiment 6:

[0121] The difference between this embodiment and the above-mentioned Embodiment 3 is that the anti-segregation cloth storage system may not be provided with a cyclone dust collector, but a single exhaust pipe 440 is introduced. One end of the exhaust pipe 440 is blown with high-pressure gas, and the exhaust port 441 of the exhaust pipe 440 is arranged in cooperation with the discharge port 221 of the distributor 200 and can jet gas from near the discharge port 221 towards the side wall of the silo 100 to provide power to assist the small particle materials to increase their translation distance. Among them, the specific way of arranging the exhaust port 441 in cooperation with the discharge port 221 in this embodiment can be set according to the positional relationship between the exhaust port 441 and the discharge port 221 in the above-mentioned Embodiments 2 to 5.

[0122] Preferably, in this embodiment, the arrangement of the exhaust pipe 440 is the same as that of the exhaust pipe 440 in Embodiment 3. The exhaust port 441 is also located below the discharge port 221, and the two also rotate synchronously. Moreover, the distance by which the gas discharged from the exhaust port 441 assists the translation of small particle materials varies positively with the rotation speed of the spreader. That is, consistent with the principle described above, when specifically setting, the distance by which the gas assists the translation of small particle materials can be adjusted by changing the magnitudes of the three parameters of the air volume, air pressure, and wind speed of the gas discharged from the exhaust port 441, so that it varies positively with the rotation speed of the spreader. The reason for such a design has been elaborated in the previous content, so it will not be repeated here.

[0123] In the above Embodiments 1 to 6, when the spreader is at the lowest rotation speed, affected by the gravitational acceleration, the material has a certain initial velocity when reaching the discharge port 221 and also undergoes a parabolic motion when discharging along the arc-shaped discharge pipe 220. Therefore, after the material falls, it has a certain translation distance, resulting in the formation of a groove in the middle of the silo 100. The appearance of this groove will cause the large particle materials to roll again to fill the groove. For this reason, in the above embodiments, holes can be opened at the bottom of the vertical pipe 210 of the spreader 200 (at the side of the axial balance compensator 600 when the axial balance compensator 600 is provided) to allow an appropriate amount of material to fall vertically to compensate for the above groove and avoid the secondary rolling of the large particle materials.

[0124] It should be noted that the small particle materials in the present invention mainly refer to materials with a particle size less than 1 mm (including dust-like materials), and the large particle materials mainly refer to materials with a particle size greater than or equal to 1 mm.

[0125] The anti-segregation spreading method and anti-segregation spreading storage system of the present invention can be applied to granite and limestone mines for dry production of high-quality manufactured sand and can be used by sand and gravel enterprises for temporary storage in the silo. Of course, it can also be used for the storage of other applicable granular materials to prevent segregation during storage.

[0126] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
