Description

Technical Field

[0001] The present invention relates to the technical field of material storage equipment, and in particular to a sorting storage bin equipment integrating storage, drying, cooling and sorting functions. Background Art

[0002] There are two main types of existing "activated silo" technologies. One is an activated silo with compressed air blowing or hammering at the bottom of the silo, and the other is an activated silo with a vibrating hopper at the bottom of the silo.

[0003] Regarding the first type, at the bottom of the silo, the material is prone to form a hardening or bridging. By blowing pulsed compressed air, the bridging material is broken and blown away, allowing the material to flow smoothly; or an electric percussion hammer is installed at the part of the silo that is prone to hardening and bridging. The percussion hammer can loosen the material and make it flow smoothly. This type of activated silo is mainly used for the storage of powdery or granular materials that are prone to bridging, such as gypsum, ammonium chloride, alkali and other materials.

[0004] Regarding the second type, the activated cone bucket of the silo and the main part of the silo are two separate and independent parts, which are connected by soft connections and springs. The high-frequency vibration of the vibration motor drives the activated cone bucket to vibrate as a whole. Vibration can prevent the material in the cone bucket from compacting or bulging, and at the same time, it can make the material fall evenly in the silo to prevent the occurrence of deviation flow and channel flow. Deviation flow refers to the material falling from one side of the silo, and channel flow refers to the material falling from several local parts of the silo, both of which are uneven material descent.

[0005] In summary, the function of the activated silo is only storage. In order to prevent the material from bridging in the silo and causing poor discharge, a compressed air blowing or knocking device is added under the silo to ensure smooth material falling and prevent blockage. The activated silo does not have the functions of drying, cooling, sorting, etc., and its application range is relatively narrow. It is mainly suitable for the storage of materials that are easy to expand.

[0006] The split type activation silo with bottom vibration cannot be made very large because the activation hopper is vibrating, and the storage capacity is small. It is mainly used in storage where the process requires the material to fall evenly, such as alkali cooling machine, etc. The compressed air blowing device of the activation silo needs to have electronic instruments such as solenoid valves and pulse controllers. If used in dusty devices and environments for a long time, the electronic components are easily damaged; due to the presence of the vibration motor, the soft connection and spring of the activation silo are all wearing parts, which are easily damaged over time and need to be replaced and repaired.

[0007] The existing drying and cooling processes for powdered materials such as salt, alkali, and nitrate are mainly processed using a fluidized bed. The principle is to use the hot air generated by a heat source to blow up the wet material in the fluidized bed to form a fluidized state, and take away the moisture in the material in the turbulent flow to meet the drying requirements. A cooling section can be set at the tail end of the fluidized bed to introduce cold air to cool the high-temperature material after drying, and then it is discharged from the equipment and can be directly packaged and stored.

[0008] In the production process of some materials such as soda ash and ammonium sulfate, a powder flow cooler is used. This cooler is a square indirect cooling device. The bin of the powder flow cooler is rectangular. The material enters from the feed port, passes through three groups (or more groups) of coolers with different functions, and is discharged from the discharge port. The cooler passes cooling water and indirectly contacts the high-temperature material in the bin to achieve the function of lowering the temperature of the material. The cooler is divided into high-temperature cooler, medium-temperature cooler, and low-temperature cooler from top to bottom. The coolers of different temperatures have different structures. The conventional high-temperature cooler is a coil structure, and the medium-temperature and low-temperature coolers are plate structures. The main function of this equipment is cooling, which reduces the temperature of the material through indirect heat exchange.

[0009] The existing drying and cooling process for powdered materials is relatively complicated. Although the fluidized bed can realize drying and cooling functions, it does not have storage functions and still needs to be transferred to downstream storage equipment. The process is long, the process equipment is complex, the floor space is large, and the investment is high. In addition, the drying process requires hot air to provide fluidization power for the material, which requires high wind power and high system energy consumption. Summary of the invention

[0010] The object of the present invention is to provide a sorting storage silo equipment which integrates storage, drying, cooling and sorting functions, and can select and combine the storage, drying, cooling, sorting and other functions according to the requirements of the application conditions, so as to solve at least one technical problem existing in the above-mentioned background technology.

[0054] Example 1

[0055] like Figures 1 to 5As shown, in this embodiment 1, a sorting storage bin device is provided, which integrates storage, drying, cooling and sorting functions. According to the requirements of the application conditions, the storage, drying, cooling, sorting and other functions can be randomly combined. The device is provided with a main bin body and a sorting bin body, wherein an air inlet pipe, a fluidizing pipe and an internal heat exchange device are arranged in the main bin body. During operation, the external heat exchange device indirectly heats the external process air and enters the main bin body through the air inlet pipe; the material flows with the assistance of hot air and enters the fluidizing pipe that is reasonably arranged and arranged, and the material is microfluidized in the fluidizing pipe, and the moisture in the material is brought into the fluidizing pipe. The sorting bin body is connected to the induced draft fan, and the hot air in the main bin body is led out by the fluidizing pipe. By controlling the hot air pressure and wind speed, the fine particles in the material are taken away in the fluidizing pipe. Different wind speeds have different particle sizes of the taken away particles, so as to realize the sorting of fine dust of the material; at the same time, an internal heat exchange device is arranged in the discharge part of the main bin body to cool the material and realize the cooling function.

[0056] The external heat exchange device and the internal heat exchange device can use different heat exchange media according to different process requirements to achieve cooling or drying functions. For example, if the external heat exchange device passes through a refrigerant, such as chilled water, the process gas entering the device is cooling air, and the cooling and sorting functions are achieved by loosening the materials; if the internal heat exchange device passes through a hot medium, such as hot water or steam, the materials are heated to remove moisture from the materials, and the function achieved at this time is the drying function.

[0057] Combination Figure 1 , Figure 2 As shown, in this embodiment 1, the specific structure of the sorting storage bin equipment includes:

[0058] Main bin body 1 and sorting bin body 2;

[0059] The main bin body 1 is provided with a feed inlet 3, and the material to be processed can be put into the main bin body 1 through the feed inlet 3. Figure 1 As shown, the feed inlet 3 is arranged at the top of the main bin body 1, and the material falls into the main bin body 1 from the feed inlet 3. The material can be dried, sorted and cooled during the falling process in the main bin body 1.

[0060] At the same time, an air inlet pipe 7 is provided inside the main bin body 1, and hot air or cooling air is introduced through the air inlet pipe 7 to achieve drying or cooling of the material.

[0061] The main bin body 1 and the sorting bin body 2 are connected through a fluidizing pipe 5, a part of which extends into the main bin body 1; the sorting bin body 2 is provided with an air inlet 4, and the sorting bin body 2 is connected with an air inlet device 6 through the air inlet 4. Under the suction of the air inlet device 6, the wind entering the main bin body 1 through the air inlet pipe 7 enters the sorting bin body through the fluidizing pipe 5, and the particles with large particle sizes continue to fall from the fluidizing pipe 5, and the particles with smaller particle sizes enter the sorting bin body 2 with the wind and fall into the sorting bin body 2, thereby realizing the sorting of materials.

[0062] At the same time, an internal heat exchange device 8 is also provided in the main bin body 1, and a hot medium or a cold medium is introduced into the internal heat exchange device 8 to achieve further drying or cooling of the material.

[0063] Combination Figure 1 , Figure 3 As shown, the air inlet pipe 7 in this embodiment 1 includes a main pipe 9 and a branch pipe 10, the branch pipe 10 is connected to the radial end surface of the main pipe 9, and the main pipe 9 is connected to the blowing device 11. The blowing device 11 can be used to introduce flowing air into the main pipe 9, and the flowing air enters the branch pipe 10 from the main pipe 9. The branch pipe 10 is provided with a plurality of jet holes 12, and the flowing air is further dispersed and sprayed from the jet holes 12 into the main bin body 1, and fully contacts with the materials falling from the feed port 3.

[0064] In this embodiment 1, in order to realize the first heating, drying or cooling of the material by flowing air, an external heat exchange device 13 is provided on the connecting pipe between the main pipe 9 and the blowing device 11. Under the action of the external heat exchange device 13, the flowing air provided by the blowing device 11 is heated or cooled, thereby providing flowing hot air or cold air to enter the main bin body 1, and heating, drying or cooling the material.

[0065] In this embodiment 1, the external heat exchange device can be a plate heat exchanger, which is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application, and long service life.

[0066] In this embodiment 1, the draft device 6 and the blowing equipment used can both be a blower, and the blower is mainly composed of the following six parts: a motor, an air filter, a blower body, an air chamber, a base (also an oil tank), and an oil drip nozzle. The blower operates eccentrically by the offset rotor in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and exhaled. The air output by the blowing equipment can enter the main bin body 1 through the air inlet pipe 7 after heat exchange in the plate heat exchanger. The draft device 6 inhales the air in the sorting bin body, and under the action of the pressure difference, the air in the main bin body 1 flows into the sorting bin body 2 through the fluidizing pipe 5. The air exhaled by the draft device 6 can be further passed into the dust removal device of the next step for dust removal.

[0067] like Figure 3 As shown, the cross section of the branch pipe 10 in this embodiment 1 is circular. Under the circular branch pipe 10, a plurality of circular holes (as air jet holes 12) are opened and evenly distributed to allow hot air to blow downward and sideways. The circular holes cannot be opened upward to prevent materials from falling into the branch pipe 10.

[0068] Combined with Figure 2 , Figure 4 , Figure 5 As shown, in this embodiment 1, one end of the fluidizing tube 5 is connected to the inner wall of the main bin body 1, and the other end of the fluidizing tube 5 passes through the side wall of the main bin body 1 and is communicated with the sorting bin body 2. One end of the fluidizing tube 5 is connected to the inner wall of the main bin body 1, and the other end passes through the inner wall of the main bin body 1 and is communicated with the sorting bin body 2, so that it can be ensured that the materials falling from the feed port 3 first enter the fluidizing tube 5 for sorting, rather than falling directly into the bottom of the main bin body 1.

[0069] Combination Figure 4 , Figure 5 As shown, in this embodiment 1, the fluidizing pipe 5 includes a main body 15. Specifically, one end of the main body 15 is connected to the inner wall of the main bin body 1, and the other end of the main body 15 passes through the inner wall of the main bin body 1 and extends into the sorting bin body 2, and an air outlet 16 is provided at this end; at the bottom of the main body 15, a drop opening 17 is provided along its length direction; air distribution plates 18 are connected to the tube walls on both sides of the drop opening 17, and wind shield plates 19 are connected to the ends of the air distribution plates 18.

[0070] like Figure 5As shown, the upper edge of the wind shield 19 extends into the main body 15, and a gap 20 is formed between the upper edge of the wind shield 19 and the side wall of the main body 1; there is a certain height difference between the lower edge of the wind shield 19 and the lower edge of the air distribution plate 18, and the height difference can prevent the material from entering the main body 15 through the drop opening between the two wind shields 19. The air distribution plate 18 is provided with a plurality of through holes, and the air-carrying material can enter the main body 15 through the through holes. The air outlet 16 is provided with a baffle plate 21, which can prevent large particles from entering the sorting bin 2 through the drop opening.

[0071] In this embodiment 1, the baffle plate 21 can be adjusted up and down to control the height of the micro-material level. For example, a slide groove is provided on the tube wall of the main body 15, and a corresponding slide rail is provided on the surface of the baffle plate 21 corresponding to the tube wall. At the same time, a threaded through hole is provided on the baffle plate 21, and a tightening bolt is provided in the threaded through hole. When the height of the baffle plate 21 needs to be adjusted, it is adjusted to a suitable height, and the baffle plate 21 can be fixed at a desired height by tightening the bolt to support the tube wall of the main body 15.

[0072] In the present embodiment 1, the through holes provided on the air distribution plate 18 may be in the shape of elongated round holes, square holes, rectangular holes, etc. Different hole forms are selected according to different material properties.

[0073] In specific use, the air blown out from the jet hole 12 first contacts the material, and continues to fall under the action of gravity. At the same time, under the action of the air induced device 6, the air enters the fluidizing tube 5 through the through hole of the air distribution plate 18 on the fluidizing tube 5, and at the same time, carries the material in. After the air carries the material into the gap 20 in the fluidizing tube 5, it changes the flow direction under the blocking action of the wind shield 19, flows upward, enters the fluidizing tube, and the flow rate decreases. Under the action of gravity, the material continues to fall in the main bin 1 from the drop port 17. For particles with smaller particle sizes, the effect of wind force is greater than the effect of their own gravity, and they enter the sorting bin from the air outlet 16 with the flowing air. When the air enters the sorting bin, the flow rate is further reduced, and the particles with smaller particle sizes fall in the sorting bin 2.

[0074] like Figure 1 As shown, a connection frame 23 is provided on the top of the bracket 22, and the connection frame 23 connects the main bin body 1 and the sorting bin body 2 through a reinforcing plate 24. A discharge port 14 is provided at the bottom of the main bin body 1 and the sorting bin body 2. When materials need to be discharged, the materials can be obtained through the discharge port 14.

[0075] Combination Fig. 9 As shown, the working principle of the sorting storage bin device described in Example 1 of the present invention when in use is as follows:

[0076] The material enters the main bin body 1 from the feed port 3 above the main bin body 1, moves downward under the action of gravity, and is blown by the blowing equipment (blower). It first passes through the heat exchange of the external heat exchange device 13, and changes from normal temperature air to hot air or cold air (the external heat exchange device 13 is a plate heat exchanger. When a high-temperature working medium is introduced into the plate heat exchanger, it becomes hot air; when a low-temperature working medium is introduced, it becomes cold air). It enters the air inlet pipe, and enters the device evenly distributed through a plurality of densely distributed jet holes 12 on the air inlet pipe, and contacts the material in the main bin body 1. Under the action of the induced draft device 6, it enters the fluidizing pipe, driving the material to be sprayed and loosened, and the hot air or cold air is discharged from the fluidizing pipe outlet 16 to the sorting bin body, taking away the moisture and tiny particles in the fluidized material; this area is the drying and sorting stage of the entire device. One layer of air inlet pipe and one layer of fluidizing pipe form a group. Multiple groups can be set according to the requirements of the bin body, and each group can be provided with multiple air inlet pipes and fluidizing pipes;

[0077] Due to the effect of the wind shield, the material flows in from the air distribution plates on both sides below the fluidizing tube and falls from the middle of the fluidizing tube. During this movement, the wind loosens the material in the gap 20 on both sides of the main body 15 of the fluidizing tube, and then the wind carries part of the water vapor and fine powder and is discharged from the air outlet 16 into the sorting bin, vaporizing the fine powder and moisture in the material and taking it away, thereby realizing the heating, drying (or cooling) and sorting functions.

[0078] After being sorted, the material continues to fall from the drop port 17 and enters the internal heat exchange section of the main bin body. The heat exchange section is arranged with an indirect heat exchanger with coils or plates, through which a refrigerant or a heat medium can be introduced. The refrigerant is cooling water or chilled water, and the heat medium is steam or hot water, heat transfer oil, etc. The cold or heat is indirectly transferred to the material through the coil or plate heat exchanger, so that the material is cooled or heated, cooled to the required temperature or dried to the required moisture, and continues to fall.

[0079] The cooled / dried materials enter the blanking section of the silo, where air inlet pipes and fluidizing pipes can be arranged again. Their functions are to further sort, heat, dry or cool the materials, and loosen them again in the fluidizing pipe to prevent them from being unable to fall due to swelling, thus ensuring the smoothness of the downward flow of the materials.

[0080] After the flowing air carrying part of water vapor and fine powder is discharged into the sorting bin, the wind speed decreases due to the expansion of volume, and the fine powder carried is settled and separated. The fine particle materials fall from the discharge port of the sorting bin, and the hot air is discharged from the induced draft device from the induced draft port of the sorting bin, and further to the dust removal system.

[0081] Example 2

[0082] like Figure 1 , Figure 2 , Figures 6 to 8As shown, this embodiment 2 provides a sorting storage silo device, which integrates storage, drying, cooling, and sorting functions. The storage, drying, cooling, sorting and other functions can be randomly combined according to the requirements of the application conditions.

[0083] The equipment is provided with a main bin and a sorting bin, wherein an air inlet pipe, a fluidizing pipe and an internal heat exchange device are arranged in the main bin 1. When working, the external heat exchange device indirectly heats the external process air and enters the main bin through the air inlet pipe; the material flows with the assistance of hot air and enters the fluidizing pipe arranged and arranged reasonably, and the material is micro-fluidized in the fluidizing pipe, and the moisture in the material is brought into the fluidizing pipe.

[0084] The sorting bin 2 is connected to the induced draft fan (induced draft device 6), and the hot air in the main bin 1 is led out through the fluidizing pipe. By controlling the hot air pressure and wind speed, the fine particles in the material are taken away in the fluidizing pipe. The wind speed is different, and the particle size of the particles taken away is different, so the fine dust of the material can be sorted. At the same time, an internal heat exchange device is set at the discharge part of the main bin to cool the material and realize the cooling function.

[0085] The external heat exchange device and the internal heat exchange device can use different heat exchange media according to different process requirements to achieve cooling or drying functions. For example, if the external heat exchange device passes through a refrigerant, such as chilled water, the process gas entering the device is cooling air, and the cooling and sorting functions are achieved by loosening the materials; if the internal heat exchange device passes through a hot medium, such as hot water or steam, the materials are heated to remove moisture from the materials, and the function achieved at this time is the drying function.

[0086] Combination Figure 1 , Figure 2 As shown, in this embodiment 2, the specific structure of the sorting storage bin equipment includes:

[0087] Main bin body 1 and sorting bin body 2;

[0088] The main bin body 1 is provided with a feed inlet 3, and the material to be processed can be put into the main bin body 1 through the feed inlet 3. Figure 1 As shown, the feed inlet 3 is arranged at the top of the main bin body 1, and the material falls into the main bin body 1 from the feed inlet 3. The material can be dried, sorted and cooled during the falling process in the main bin body 1.

[0089] At the same time, the main bin body 1 is provided with an air inlet pipe 7, through which hot air or cooling air is introduced to achieve drying or cooling of the material.

[0090] The main bin body 1 and the sorting bin body 2 are connected through a fluidizing pipe 5, a part of which extends into the main bin body 1; the sorting bin body 2 is provided with an air inlet 4, and the sorting bin body 2 is connected with an air inlet device 6 through the air inlet 4. Under the suction of the air inlet device 6, the wind entering the main bin body 1 through the air inlet pipe 7 enters the sorting bin body through the fluidizing pipe 5, and the particles with large particle sizes continue to fall from the fluidizing pipe 5, and the particles with smaller particle sizes enter the sorting bin body 2 with the wind and fall into the sorting bin body 2, thereby realizing the sorting of materials.

[0091] At the same time, an internal heat exchange device 8 is also provided in the main bin body 1, and a hot medium or a cold medium is introduced into the internal heat exchange device 8 to achieve further drying or cooling of the material.

[0092] Combination Figure 1 , Figure 6 As shown, the air inlet pipe 7 in this embodiment 2 includes a main pipe 9 and a branch pipe 10, the branch pipe 10 is connected to the radial end surface of the main pipe 9, and the branch pipe 10 extends into the main bin body 1. The main pipe 9 is connected to a blowing device 11. The blowing device 11 can be used to introduce flowing air into the main pipe 9, and the flowing air enters the branch pipe 10 from the main pipe 9. The branch pipe 10 is provided with a plurality of jet holes 12, and the flowing air is further dispersed and sprayed from the jet holes 12 into the main bin body 1, and fully contacts with the materials falling from the feed port 3.

[0093] In this embodiment 2, in order to realize the first heating, drying or cooling of the material by the flowing air, an external heat exchange device 13 is provided on the connecting pipe between the main pipe 9 and the blowing device 11. Under the action of the external heat exchange device 13, the flowing air provided by the blowing device 11 is heated or cooled, thereby providing flowing hot air or cold air to heat, dry or cool the material.

[0094] In this embodiment 2, the external heat exchange device can be a plate heat exchanger, which is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application, and long service life.

[0095] The internal heat exchange device 8 is a coil structure. The coil can be placed horizontally or vertically. Both ends of the coil extend out of the main bin body 1 and are connected to the cold medium source or the hot medium source. The cold medium or the hot medium flows inside, and the material is cooled or heated by indirect heat exchange. The internal heat exchange device 8 can also be a plate heat exchanger. The internal heat exchange device 8 can further heat and dry or cool the material, so that the material discharged from the bin body reaches the required moisture or temperature, meeting the use requirements of the subsequent process.

[0096] In this embodiment 2, the draft device 6 and the blowing device 11 used can both be blowers, and the blower is mainly composed of the following six parts: a motor, an air filter, a blower body, an air chamber, a base (also an oil tank), and an oil drip nozzle. The blower operates eccentrically by the offset rotor in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and exhaled. The air exhaled by the blowing device can enter the main bin body 1 through the air inlet pipe 7 after heat exchange in the plate heat exchanger. The draft device 6 inhales the air in the sorting bin body, and under the action of the pressure difference, the air in the main bin body 1 flows into the sorting bin body 2 through the fluidizing pipe 5. The air exhaled by the draft device 6 can be further passed into the dust removal device of the next step for dust removal.

[0097] like Figure 6 As shown, the cross section of the branch pipe 10 in this embodiment 2 is square or diamond-shaped. If it is square or diamond-shaped, one side of the branch pipe 10 is on the top and the opposite side is on the bottom. Side blowing ports (air jets 12) are opened on the four side panels, and a protruding wind shield is set on the upper edge of the blowing port to make the wind flow downward or sideways and downward, so as to prevent materials from falling into the air inlet pipe.

[0098] like Figure 2 , Figure 7 , Figure 8 As shown, in this embodiment 2, one end of the fluidizing tube 5 is connected to the inner wall of the main bin body 1, and the other end of the fluidizing tube 5 passes through the side wall of the main bin body 1 and is communicated with the sorting bin body 2. One end of the fluidizing tube 5 is connected to the inner wall of the main bin body 1, and the other end passes through the inner wall of the main bin body 1 and is communicated with the sorting bin body 2, so that it can be ensured that the materials falling from the feed port 3 first enter the fluidizing tube 5 for sorting, rather than falling directly into the bottom of the main bin body 1.

[0099] Combination Figure 7 , Figure 8 As shown, in this embodiment 1, the fluidizing pipe 5 includes a main body 15. Specifically, one end of the main body 15 is connected to the inner wall of the main bin body 1, and the other end of the main body 15 passes through the inner wall of the main bin body 1 and extends into the sorting bin body 2, and an air outlet 16 is provided at this end; at the bottom of the main body 15, a drop opening 17 is provided along its length direction; air distribution plates 18 are connected to the tube walls on both sides of the drop opening 17, and wind shield plates 19 are connected to the ends of the air distribution plates 18.

[0100] like Figure 5 As shown, the upper edge of the wind shield 19 extends into the main body 15, and a gap 20 is formed between the wind shield 19 and the side wall of the main body 1; the lower edge of the wind shield 19 is connected to the air distribution plate 18, and the main body 15 can be provided with an expansion section (such as Figure 8As shown, the side panels of the main body 15 on both sides above the gap protrude outward to form an expanded section of the main body 15 space) to reduce the wind speed, prevent particles with larger particle sizes from flowing into the sorting bin 2, and increase the sorting accuracy. The air distribution plate 18 is provided with a plurality of through holes, and the air-carrying materials can enter the main body 15 through the through holes. The air outlet 16 is provided with a baffle plate 21, which can control the height of the microfluidization.

[0101] In this embodiment 1, the baffle plate 21 can be adjusted up and down to control the height of the micro-material level. For example, a slide groove is provided on the tube wall of the main body 15, and a corresponding slide rail is provided on the surface of the baffle plate 21 corresponding to the tube wall. At the same time, a threaded through hole is provided on the baffle plate 21, and a tightening bolt is provided in the threaded through hole. When the height of the baffle plate 21 needs to be adjusted, it is adjusted to a suitable height, and the baffle plate 21 can be fixed at a desired height by tightening the bolt to support the tube wall of the main body 15.

[0102] In the present embodiment 2, the through holes provided on the air distribution plate 18 may be in the shape of elongated round holes, square holes, rectangular holes, etc. Different hole forms are selected according to different material properties.

[0103] In specific use, the air blown out from the jet hole 12 first contacts the material, and continues to fall under the action of gravity. At the same time, under the action of the air induced device 6, the air enters the fluidizing tube 5 through the through hole of the air distribution plate 18 on the fluidizing tube 5, and at the same time, carries the material in. After the air carries the material into the gap 20 in the fluidizing tube 5, it changes the flow direction under the blocking action of the wind shield 19, flows upward, enters the fluidizing tube, and the flow rate decreases. Under the action of gravity, the material continues to fall in the main bin 1 from the drop port 17. For particles with smaller particle sizes, the effect of wind force is greater than the effect of their own gravity, and they enter the sorting bin from the air outlet 16 with the flowing air. When the air enters the sorting bin, the flow rate is further reduced, and the particles with smaller particle sizes fall in the sorting bin 2.

[0104] like Figure 1 As shown, a connection frame 23 is provided on the top of the bracket 22, and the connection frame 23 connects the main bin body 1 and the sorting bin body 2 through a reinforcing plate 24. A discharge port 14 is provided at the bottom of the main bin body 1 and the sorting bin body 2. When materials need to be discharged, the materials can be obtained through the discharge port 14.

[0105] Combination Fig. 9 As shown, the working principle of the sorting storage bin device described in Example 2 of the present invention when in use is as follows:

[0106] The material enters the main bin body 1 from the feed port 3 above the main bin body 1, moves downward under the action of gravity, and is blown by the blowing equipment (blower). It first passes through the heat exchange of the external heat exchange device 13, and changes from normal temperature air to hot air or cold air (the external heat exchange device 13 is a plate heat exchanger. When a high-temperature working medium is introduced into the plate heat exchanger, it becomes hot air; when a low-temperature working medium is introduced, it becomes cold air). It enters the air inlet pipe, and enters the device evenly distributed through a plurality of densely distributed jet holes 12 on the air inlet pipe, and contacts the material in the main bin body 1. Under the action of the induced draft device 6, it enters the fluidizing pipe, driving the material to be sprayed and loosened, and the hot air or cold air is discharged from the fluidizing pipe outlet 16 to the sorting bin body, taking away the moisture and tiny particles in the fluidized material; this area is the drying and sorting stage of the entire device. One layer of air inlet pipe and one layer of fluidizing pipe form a group. Multiple groups can be set according to the requirements of the bin body, and each group can be provided with multiple air inlet pipes and fluidizing pipes;

[0107] Due to the effect of the wind shield, the material flows in from the air distribution plates on both sides below the fluidizing tube and falls from the middle of the fluidizing tube. During this movement, the wind loosens the material in the gap 20 on both sides of the main body 15 of the fluidizing tube, and then the wind carries part of the water vapor and fine powder and is discharged from the air outlet 16 into the sorting bin, vaporizing the fine powder and moisture in the material and taking it away, thereby realizing the heating, drying (or cooling) and sorting functions.

[0108] After being sorted, the material continues to fall from the drop port 17 and enters the internal heat exchange section of the main bin body. The heat exchange section is arranged with an indirect heat exchanger with coils or plates, through which a refrigerant or a heat medium can be introduced. The refrigerant is cooling water or chilled water, and the heat medium is steam or hot water, heat transfer oil, etc. The cold or heat is indirectly transferred to the material through the coil or plate heat exchanger, so that the material is cooled or heated, cooled to the required temperature or dried to the required moisture, and continues to fall.

[0109] The cooled / dried materials enter the blanking section of the silo, where air inlet pipes and fluidizing pipes can be arranged again. Their functions are to further sort, heat, dry or cool the materials, and loosen them again in the fluidizing pipe to prevent them from being unable to fall due to swelling, thus ensuring the smoothness of the downward flow of the materials.

[0110] After the flowing air carrying part of water vapor and fine powder is discharged into the sorting bin, the wind speed decreases due to the expansion of volume, and the fine powder carried is settled and separated. The fine particle materials fall from the discharge port of the sorting bin, and the hot air is discharged from the induced draft device from the induced draft port of the sorting bin, and further to the dust removal system.

[0111] like Figure 2 As shown, in this embodiment 2, several groups of air inlet pipes and fluidizing pipes can be further arranged on the lower side of the internal heat exchange device 4 to continue sorting, heating and drying or cooling and loosening the materials.

[0112] To sum up, the sorting storage bin equipment described in the embodiment of the present invention integrates the functions of drying, sorting, cooling, loosening, etc. in the storage bin on the basis of the stored materials, and has diversified functions. Compared with the equipment with each function independently set, it can shorten the material flow, reduce the number of equipment, reduce investment, reduce maintenance, and reduce the floor space, etc.; an air inlet pipe and a fluidizing pipe are arranged in the bin body, so that hot air / cold air can be introduced into the storage bin, and in the process of moving together with the materials in the bin, the materials are loosened and the surface moisture in the materials is taken away, so that the loosening and drying functions can be realized at the same time; the wind introduced into the bin body can take away the moisture of the materials, and through the reasonable design of the fluidizing pipe structure, it can take away the fine powder in the materials while loosening the materials, and settle through the separation bin to realize the sorting of the fine powder, and the sorted fine powder materials are discharged through the discharge port of the sorting bin body, and the large particle materials are discharged through the discharge port at the bottom of the main bin body. A layer of air inlet pipes and a layer of air outlet pipes form a group, multiple air inlet pipes can be set on each layer, multiple fluidizing pipes can be set on each layer, and multiple groups of air inlet pipes and fluidizing pipes can be set in the warehouse body. Through reasonable arrangement, wind can be introduced into various parts of the warehouse body, and materials in various places can be blown and loosened. In the process of drying, sorting and loosening, it can ensure that the materials fall evenly and achieve simultaneous falling of the whole.

[0113] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative work on the basis of the technical solution disclosed in the present invention should be included in the scope of protection of the present invention.
