DETAILED DESCRIPTION

[0043] The content of the utility model will be described clearly and completely in combination with the drawings, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. In combination with the embodiments in the utility model, other embodiments obtained by the person skilled in the art without making creative labor all belong to the protection scope of the utility model.

[0044] Embodiment 1

[0045] In the embodiment, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a storage bin is provided, which comprises a bin barrel 1 and a plurality of fixed material discs 2;

[0046] The bin barrel 1 is provided with a cooling cavity, and the plurality of fixed material discs 2 are respectively arranged in the cooling cavity, wherein the plurality of fixed material discs 2 are arranged at intervals along the vertical direction, and the diameter of any fixed material disc 2 is parallel to the horizontal direction.

[0047] Any one fixed tray 2 is fixedly connected with the bin 1 respectively.

[0048] A plurality of fixed trays 2 are arranged in the vertical direction in the storage bin, that is, the storage bin is arranged in layers, and each layer is stacked with master batches, thereby increasing the contact area of the master batches with air; compared with the scheme of simply stacking the master batches for cooling, the scheme of using a plurality of fixed trays 2 in the embodiment can increase the contact area of the master batches with air in the same volume, so that the heat exchange efficiency of the master batches with air is higher, thereby quickly reducing the temperature of the master batches.

[0049] Further, in the foregoing scheme, when the master batches are put on each fixed tray 2, dust (the composition of the dust is the same as that of the master batches) contained in the master batches can cause dust flying phenomenon; after the master batches are put on any one fixed tray 2, if the storage bin is placed in an open area, when the natural wind blows through the master batches, dust flying phenomenon can also be caused; during the process of taking the master batches from any one fixed tray 2, dust flying phenomenon can also be caused; the above dust flying phenomenon respectively causes some pollution to the air environment, so the dust flying phenomenon should be reduced as much as possible.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the bin 1 of the storage bin in the embodiment includes a side panel 3, a top panel 4 and a bottom panel 5, the side panel 3 is constructed as a cylindrical structure with an upper and lower opening, the top panel 4 covers the upper opening, the bottom panel 5 covers the lower opening, and a cooling cavity is limited between the side panel 3, the top panel 4 and the bottom panel 5;

[0051] The cooling cavity is in an isolated state from the atmosphere through the side panel 3, the top panel 4 and the bottom panel 5;

[0052] Any one fixed tray 2 is fixedly connected with the side panel 3, and in the vertical direction, the plurality of fixed trays 2 divide the cooling cavity into a plurality of cooling areas.

[0053] The bin 1 is configured as a closable closed container structure through the side panel 3, the top panel 4 and the bottom panel 5; the cooling cavity in the bin 1 and the atmosphere outside the bin 1 are isolated through the bin 1; it should be understood that the closable closed container structure is described in detail in the following content, which is not described here.

[0054] In the process of putting the master batch into the fixed material tray 2 in the silo 1, the external master batch containing dust enters the cooling cavity in the silo 1, and the master batch containing dust falls on the fixed material tray 2 under the action of gravity, and is affected by the reaction force of the fixed material tray 2, some master batches and dust produce splashing state, thereby forming dust raising phenomenon; but, because the silo 1 is configured as a closed container structure, so that the dust raising phenomenon is limited in the cooling cavity in the silo 1, so that the dust in the silo 1 will not cause dust raising phenomenon outside the silo 1.

[0055] After the master batch is put into the fixed material tray 2, because the silo 1 is configured as a closable closed container, so that the air (natural wind or pressurized wind) outside the silo 1 enters the cooling cavity in the silo 1, and the air exchanges heat with the master batch in the cooling cavity, and then the air is discharged outside the silo 1, the position of the master batch blown by the air is still in the silo 1, so that the dust in the silo 1 will not cause dust raising phenomenon outside the silo 1; it should be understood that, in order to avoid the dust mixed with the air discharged outside the silo 1 causing dust raising phenomenon outside the silo 1, the mixture of the air and the dust discharged outside the silo 1 should be filtered by a dust remover or the like, but this is not the technical problem to be solved by the embodiment; even if facing this technical problem, the flow path of the mixture of the air and the dust discharged outside the silo 1 can be limited by a simple exhaust duct, so that the mixture of the air and the dust can not flow into the atmosphere.

[0056] After the master batch is cooled, in the process of taking the master batch from each fixed material tray 2, whether the master batch is taken manually by tools or the master batch flows out of the silo 1 naturally by gravity, the movement path of the master batch containing dust is always limited in the cooling cavity in the silo 1, so that the dust in the silo 1 will not cause dust raising phenomenon outside the silo 1; it should be understood that, the dust raising phenomenon outside the silo 1 caused by the master batch containing dust which has been transported outside the silo 1 is not the technical problem to be solved by the embodiment; even if facing this technical problem, the automatic discharging mode can be used, and a sealed master batch conveying device is arranged at the bottom of the silo 1, so that the dust can not splash into the atmosphere; in addition, the sealed master batch conveying device is similar to the sealed grain conveying device.

[0057] Further, the storage silo in the embodiment is configured to put the master batch into each fixed material tray 2 in an automatic manner, and is configured to discharge the master batch outside the storage silo in an automatic manner; however, because the plurality of fixed material trays 2 in the silo 1 are arranged in a vertical direction in layers, then how the master batch is put into each fixed material tray 2, and how the master batch on each fixed material tray 2 moves to the lower part of the fixed material tray 2, and then the master batch is discharged to the outside of the storage silo through the discharge port 10, become the technical problems to be solved.

[0058] Referring to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the side enclosure 3 of the storage bin in the embodiment is further provided with a feeding port 6, and each cooling area is respectively provided with a feeding port 6;

[0059] The fixed tray 2 is provided with a material passing port 7, and the fixed tray 2 further comprises a valve 8, which is located below the material passing port 7 and covers the material passing port 7. The valve 8 is detachably connected with the fixed tray 2. The fixed tray 2 is provided with a material scraping plate 9 above the fixed tray 2, which is in contact with the fixed tray 2 and movably connected with the fixed tray 2. The material scraping plate 9 is located below the feeding port 6;

[0060] The bottom enclosure 5 is provided with a material discharging port 10.

[0061] For the whole process of putting the master batch into the storage bin, a special feeding tool needs to be used. However, the special feeding tool is not the technical problem to be solved in the embodiment. Even if the technical problem exists, the existing lifting conveyor belt and the like can be used as the special feeding tool.

[0062] For the storage bin in the embodiment, a plurality of fixed trays 2 are arranged in the cooling cavities in the bin barrel 1, and the plurality of fixed trays 2 are arranged in layers and at intervals. This causes the master batch on the fixed tray 2 in the upper layer to be unable to fall onto the fixed tray 2 in the lower layer under the action of gravity, thereby causing the difficulty of putting the master batch into each fixed tray 2.

[0063] In the embodiment, a plurality of feeding ports 6 are arranged on the side enclosure 3, and each cooling area is respectively provided with a feeding port 6. Therefore, in the process of putting the master batch into the fixed tray 2, the special feeding tool as described above is used to put the master batch into each feeding port 6, so that the fixed tray 2 in each cooling area can respectively stack the master batch.

[0064] In the embodiment, the fixed tray 2 is provided with a material passing port 7, and the cooling area in the upper layer can be connected with the cooling area in the lower layer through the material passing port 7. This enables the master batch on the fixed tray 2 in the upper layer to fall onto the fixed tray 2 in the lower layer through the material passing port 7;

[0065] In the embodiment, in order to avoid the master batch on each fixed tray 2 from falling into the lower cooling area through the material outlet 7 of the fixed tray 2 during the cooling process, a valve 8 is arranged below the material outlet 7 of each fixed tray 2; when the valve core of the valve 8 is in the blocking state, the material outlet 7 is blocked by the valve core of the valve 8, so that the material outlet 7 cannot communicate the cooling area in the upper layer and the cooling area in the lower layer, and then the master batch on each fixed tray 2 cannot fall into the cooling area in the lower layer through the material outlet 7 during the cooling process; on the contrary, when the valve core of the valve 8 is in the conducting state, the material outlet 7 is not blocked by the valve core of the valve 8, so that after the master batch in each layer is cooled, it can fall into the cooling area in the lower layer through the material outlet 7.

[0066] In addition, even if a plurality of feeding ports 6 are arranged and each cooling area is respectively provided with a feeding port 6, it is still easy to cause the master batch to form a large accumulation state near the feeding port 6 and a small accumulation state far from the feeding port 6, thereby causing the master batch to be unevenly stacked on each fixed tray 2;

[0067] In the embodiment, the material scraping plate 9 can rotate relative to the fixed tray 2, so that during the process of putting the master batch on each fixed tray 2, the master batch accumulated near the feeding port 6 can be pushed by the material scraping plate 9 to the position far from the feeding port 6, so that the master batch on each fixed tray 2 is evenly stacked;

[0068] In addition, during the process of discharging the master batch from the storage bin, the material scraping plate 9 can push the master batch far from the material outlet 7 to the position of the material outlet 7, so that the master batch on each fixed tray 2 is discharged from the current cooling area as much as possible and enters the cooling area in the lower layer, until the master batch falls to the position of the discharge port 10 of the bin barrel 1 and is discharged to the outside of the storage bin.

[0069] Further, on the basis of the foregoing scheme, how to drive the material scraping plate 9 to rotate relative to the fixed tray 2 is preferably achieved by the following technical scheme.

[0070] Referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 , the storage bin in the embodiment further comprises a motor 11, a speed reducer 12, a gear set 13 and an outer ring gear 14, the input shaft of the speed reducer 12 is connected with the motor 11, the output shaft of the speed reducer 12 penetrates the first hole 24 on the side wall 3, and the output shaft is coaxially connected with the gear set 13;

[0071] The outer gear ring 14 has an inner circumferential surface 17, and the space between the inner circumferential surface 17 is a mounting space, and the all end portions of the scrapers 9 are fixedly connected with the inner circumferential surface 17;

[0072] The outer teeth of the gear set 13 and the outer gear ring 14 are engaged.

[0073] Each of the scrapers 9 is respectively provided with a motor 11, a speed reducer 12, a gear set 13 and an outer gear ring 14, and the transmission mode and connection mode of the motor 11 and the speed reducer 12 are well known to those skilled in the art, and will not be described in detail in the present embodiment. The scraper 9 takes the motor 11 and the speed reducer 12 as a power source, and forms a transmission structure through the outer gear ring 14 on the scraper 9 and the gear set 13 connected with the output shaft of the speed reducer 12, so that the motor 11 can drive the scraper 9 to rotate in the circumferential direction relative to the fixed tray 2.

[0074] Further, in the foregoing scheme, how to speed up the air flow speed on the surface of the master batch on each fixed tray 2, and further improve the heat dissipation efficiency of the master batch, preferably using the following technical scheme to achieve.

[0075] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the side enclosure 3 of the storage bin in the present embodiment is provided with an air inlet 18 and an air outlet 19, and each cooling area is respectively provided with at least one air inlet 18 and at least one air outlet 19.

[0076] From the perspective of speeding up the air flow speed on the surface of the master batch, it is necessary to use an air pressurizing device, such as an air compressor, to obtain compressed air, but this is not the technical problem to be solved in the present embodiment; even if faced with this technical problem, the air compressor and pipeline in the prior art can be used.

[0077] In the present embodiment, since the fixed tray 2 is arranged in the bin barrel 1, the master batch is put on the fixed tray 2, so that the master batch in the bin barrel 1 is isolated from the atmosphere outside the bin barrel 1 by the bin barrel 1 itself, and therefore, the air flow speed on the surface of the master batch cannot be increased by increasing the air flow speed outside the bin barrel 1 by an electric fan or the like; therefore, in the present embodiment, mainly consider the compressed air obtained by the foregoing air pressurizing device, and how to introduce the compressed air into the bin barrel 1, and consider discharging the compressed air in the bin barrel 1 to the outside of the bin barrel 1;

[0078] In the embodiment, at least one air inlet 18 is arranged in each cooling area, and the air inlet 18 is communicated with the air pressurizing device, so that each cooling area can obtain compressed air through the air inlet 18, and the air in each cooling area is discharged to the outside of the barrel 1 through the air outlet 19; because the flow speed of the compressed air is relatively high, the flow speed of the compressed air flowing through the surface of the master batch is higher than the flow speed of the air flowing through the surface of the master batch under natural pressure, so that the heat dissipation efficiency of the master batch is improved.

[0079] Further, in the foregoing scheme, how to determine whether the master batch is stacked on each fixed tray 2, and the cooling area still has a gap that can make the air circulate, becomes a technical problem to be solved.

[0080] Referring to Figure 2 and Figure 11 , the storage bin in the embodiment further comprises a laser emitter 16, a laser receiver 15 and a controller 23, and each cooling area is respectively provided with the laser emitter 16 and the laser receiver 15;

[0081] In the same cooling area, the laser receiver 15 is used to receive the laser emitted by the laser emitter 16, and the laser emitter 16 and the laser receiver 15 are detachably connected with the side coaming 3; along the vertical direction, the positions of the laser emitter 16 and the laser receiver 15 are respectively above the scraping plate 9 and below the feeding port 6; along the circumferential direction of the side coaming 3, the laser emitter 16 and the laser receiver 15 are respectively spaced apart from the feeding port 6;

[0082] Each laser emitter 16 and each laser receiver 15 are electrically connected with the controller 23.

[0083] In the process of feeding the master batch to the fixed tray 2, the laser emitter 16 and the laser receiver 15 are started, at this time, because the height of the master batch stack is relatively low, the laser receiver 15 can receive the laser emitted by the laser generator; after the laser receiver 15 receives the laser, photoelectric conversion is generated to form an electric signal, and the electric signal is defined as a height electric signal; the height electric signal is sent to the controller 23 by the laser receiver 15, so that when the controller 23 receives the height electric signal, the controller 23 obtains the judgment result that the master batch of the current fixed tray 2 is not full; as the master batch gradually increases, when the stacking height of the master batch is higher than the laser emitted by the laser emitter 16, the laser is blocked by the master batch, so that the laser receiver 15 cannot receive the laser, the foregoing height electric signal is eliminated, and the control mechanism loses the height electric signal to obtain the judgment result that the master batch of the current fixed tray 2 is full.

[0084] Since the laser transmitter 16 and the laser receiver 15 are respectively located below the feeding port 6, when the master batch is stacked to a certain height and blocks the laser of the laser transmitter 16, the height of the current master batch is parallel to or lower than the height of the feeding port 6, so that the phenomenon that the master batch is discharged from the feeding port 6 to the outside of the silo 1 is avoided, and the top surface formed after the master batch is stacked still has a spacing between the upper fixed tray 2 or the top surrounding plate 4 of the silo 1, so that air can flow in the cooling area.

[0085] Further, in the foregoing scheme, how to judge whether the master batch in the silo 1 has completed cooling is preferably realized by the following technical scheme.

[0086] Referring to Figure 11 , the storage silo in the embodiment further comprises a temperature sensor 22 and an audible and visual alarm, and one temperature sensor 22 is arranged in each cooling area;

[0087] The audible and visual alarm is arranged outside the silo 1, and each temperature sensor 22 is electrically connected with a controller 23, and the controller 23 is electrically connected with the audible and visual alarm.

[0088] After the master batch is put on the fixed tray 2, the temperature sensor 22 is started, the temperature of the master batch is detected through the temperature sensor 22, and a temperature electric signal is obtained; the temperature sensor 22 transmits the temperature electric signal to the controller 23, the controller 23 converts the temperature electric signal into temperature data, and compares the temperature data with the natural temperature or the preset reference temperature, if the temperature data is equal to or lower than the natural temperature or the preset reference temperature, then the controller 23 obtains a judgment result that the current master batch completes cooling; otherwise, if the temperature data is higher than the natural temperature or the preset reference temperature, then the controller 23 obtains a judgment result that the current master batch does not complete cooling.

[0089] Further, referring to Figure 6 and Figure 7 , the number of the material passing ports 7 on each fixed tray 2 of the storage silo in the embodiment is at least two;

[0090] On the same fixed tray 2, each material passing port 7 is located between the circumferential edge and the center of the fixed tray 2.

[0091] In the embodiment, the master batch on each fixed tray 2 should be discharged to the outside of the storage silo as much as possible, however, the actual difficulty is that after the master batch on each fixed tray 2 is driven by the scraping plate 9, some master batches still remain on the fixed tray 2 and move with the rotation of the scraping plate.

[0092] For this phenomenon, the embodiment is provided with a plurality of material passing ports 7, and the positions of each material passing port 7 are different; specifically,

[0093] Assuming that each fixed tray 2 is provided with two material passing openings 7, then,

[0094] The first scheme, the sum of the diameters of the two material passing openings 7 should be slightly smaller than the diameter of the fixed tray 2, so that the two material passing openings 7 can be closely arranged along one of the radii of the fixed tray 2 and do not affect the connection of the valve 8 and the fixed tray 2, or one of the material passing openings 7 can be arranged near the circumferential edge of the fixed tray 2, and the other material passing opening 7 can be arranged near the center of the fixed tray 2.

[0095] The second scheme, the two material passing openings 7 can be arranged separately along two radii of the fixed tray 2, one of the material passing openings 7 is arranged near the circumferential edge of the fixed tray 2, and the other material passing opening 7 is arranged near the center of the fixed tray 2.

[0096] Assuming that each fixed tray 2 is provided with three or four material passing openings 7, then, the three or four material passing openings 7 can be arranged in the same radius direction or in the same diameter direction according to the first scheme described above, or the three or four material passing openings 7 can be arranged in different radius directions according to the second scheme described above.

[0097] No matter which one of the first scheme or the second scheme described above is adopted, the actual arrangement positions of the multiple material passing openings 7 can be converted to the same radius or diameter of the fixed tray 2, respectively, which makes the circumferential areas determined by any one of the material passing openings 7 adjacent to each other or overlap with each other, so that the master batch is moved in any one of the circumferential areas by the scraper 9 during the rotation of the scraper 9, and the master batch in any one of the circumferential areas falls into the lower cooling space through one of the material passing openings 7, thereby reducing the number of master batch accumulated on the fixed tray 2.

[0098] Further, the valve 8 of the storage bin in the embodiment is an electric disc valve or an electric ball valve.

[0099] Further, referring to Figure 1 , Figure 2 and Figure 3 , the storage bin in the embodiment further comprises a support 20, the support 20 comprises a first supporting portion 21 connected to the bin barrel 1 and a second supporting portion away from the bin barrel 1, the first supporting portion 21 and the second supporting portion have a spacing therebetween, and the discharge opening 10 is located between the first supporting portion 21 and the second supporting portion.

[0100] The support 20 is used to support the storage bin, so that the discharge opening 10 is away from the ground.

[0101] The use process of the utility model is as follows:

[0102] When the master batch is fed, the master batch enters the inside of the storage bin through the feeding port 6, which can be simultaneously fed through multiple feeding ports 6 or sequentially fed through the feeding ports 6 from top to bottom or from bottom to top, and the feeding mode is not limited herein.

[0103] In the same cooling area, the motor 11 is started when the feeding is started, and the motor 11 sequentially transmits power to the speed reducer 12, the gear set 13 connected with the output shaft of the speed reducer 12, and the outer ring gear 14 engaged with the gear set 13, so as to drive the scraper plate 9 to rotate relative to the fixed tray 2 in the circumferential direction, so that the master batch is uniformly distributed on each fixed tray 2 during the feeding process, and the master batch is prevented from blocking the feeding port 6 in the storage bin.

[0104] In the same cooling area, the laser emitter 16 and the laser receiver 15 are started by the controller 23 when the feeding is started, and whether the height of the currently stacked master batch reaches the preset height is judged by judging whether the laser emitted by the laser emitter 16 can be received by the laser receiver 15 during the feeding of the master batch. When the laser can be received by the laser receiver 15, it indicates that the laser is not blocked by the stacked master batch, and the height of the master batch on the fixed tray 2 has not reached the preset height, and the feeding should be continued. When the laser cannot be received by the laser receiver 15, it indicates that the laser is blocked by the stacked master batch, and the height of the master batch on the fixed tray 2 reaches or exceeds the preset height, at which time the feeding is completed, and the feeding should be stopped.

[0105] When the feeding is completed, the motor 11 is turned off, and the laser emitter 16 and the laser receiver 15 are turned off by the controller 23. After the feeding is completed, the master batch enters the cooling state.

[0106] When the master batch starts to cool, the air pressurizing device is started, the air pressurizing device blows air into the inside of the storage bin through the air inlets 18 of all the cooling areas, and the air in the inside of the storage bin leaves the inside of the storage bin through the air outlets 19 of the same cooling area after heat exchange with the master batch; when the master batch starts to cool, the temperature sensors 22 of all the cooling areas start to measure the temperature of the master batch, and the controller 23 judges whether the temperature of the master batch decreases to the preset temperature according to the signals transmitted by the temperature sensors 22. When the controller 23 judges that the temperature of the master batch decreases to the preset temperature, the controller 23 judges that the cooling is completed, and the controller 23 sends a signal to the sound-light alarm to alarm to remind the operator.

[0107] When the master batch is cooled, the air pressurizing device of the air inlet 18 and the temperature sensor 22 are turned off. After the master batch is cooled, the master batch enters the discharging state.

[0108] When the master granules start to be discharged, all the motors 11 and all the valves 8 on all the fixed trays 2 are opened, so that the valve cores of the valves 8 are switched from the cut-off state to the on state, the motors 11 transmit power to the scrapers 9, so that the scrapers 9 rotate relative to the fixed trays 2 in the circumferential direction, so that the scrapers 9 can push the master granules on the fixed trays 2 to the discharge ports 7; the valves of the discharge ports 7 of each layer of fixed trays 2 are opened, and in the vertical direction, the master granules of the upper fixed trays 2 fall to the lower fixed trays 2 through the discharge ports 7, and so on, the master granules fall to the lowermost fixed trays 2, and the master granules on the lowermost fixed trays 2 fall to the discharge port 10 through the discharge port 7 on the lowermost fixed trays 2, and the master granules leave the inside of the storage bin through the discharge port 10, and the discharging is completed.

[0109] The storage bin provided by the utility model, through setting multiple fixed trays 2 which are spaced apart in the vertical direction, the contact area of the master granules with air is increased; through setting the air inlet 18 and the air outlet 19, the air flow speed on the surface of the master granules is improved, the flow of the air which exchanges heat with the master granules is increased, so that the heat exchange speed of the master granules with air is accelerated, the master granules in the storage bin are rapidly cooled, the problem that the temperature of the master granules is too high when bagging is solved, so that the phenomenon that the master granules are broken due to mutual extrusion can be reduced, and the problem of dust generated in the reproduction process of the master granules is reduced.

[0110] Through setting the scrapers 9 which can rotate relative to the fixed trays 2 and the cooperation of the multiple discharge ports 7, the efficiency of the master granules passing through the discharge ports 7 is improved, so that the storage efficiency of the master granules in the storage bin is improved.

[0111] The preferred embodiments are only used to illustrate the utility model, and do not limit the patent range of the utility model, and any equivalent structural transformation or direct or indirect application in other related technical fields based on the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
