DETAILED DESCRIPTION

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise stated, directional words such as "up, down, top, bottom" refer to up, down, top, bottom in the direction of gravity during actual use. In addition, "inside and outside" refer to "inside and outside" relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0020] The present disclosure provides a storage device for biomass fuel, referring to Figures 1 to 4 As shown in the figure, the storage device includes: a storage bin 1, having a feed port 101 arranged at the top and a discharge port 102 arranged at the bottom; a dryer 2, having an air outlet (not shown in the figure); at least one first ventilation pipe 3, which is connected to the air outlet and the connection between the first ventilation pipe 3 and the air outlet is arranged at the bottom of the first ventilation pipe 3, the first ventilation pipe 3 is inserted into the storage bin 1 along the height direction of the storage bin 1 and a plurality of first ventilation holes (not shown in the figure) are opened on the pipe wall; a sealing slider 4 is sealingly arranged in the first ventilation pipe 3 to separate the first ventilation pipe 3 into a first branch pipe 31 and a second branch pipe 32 which are not connected to each other, and the first branch pipe 31 is arranged below the second branch pipe 32; and a driving member 5, which is transmission-connected to the sealing slider 4 and drives the sealing slider 4 to move along the extension direction of the first ventilation pipe 3.

[0021] Through the above technical solution, when the storage device provided by the present invention is in use, the wind flow generated by the dryer 2 can enter the first ventilation duct 3 from below, and be blown into the storage bin 1 through the first ventilation hole opened in the wall of the first ventilation duct 3, thereby realizing ventilation and drying of the materials stored in the storage bin 1. Among them, since the discharge port 102 is set at the bottom of the storage bin 1, as the material is discharged along the discharge port 102 at the bottom, the material height in the storage bin 1 will continue to decrease. Therefore, the present invention discloses a sealing slider 4 is sealed in the first ventilation pipe 3, and the sealing slider 4 divides the first ventilation pipe 3 into a first branch pipe 31 and a second branch pipe 32 that are not connected to each other, wherein the first branch pipe 31 is located below the second branch pipe 32, and the driving member 5 is transmission-connected to the sealing slider 4 and can drive the sealing slider 4 to move along the extension direction of the first ventilation pipe 3. In this way, the position of the sealing slider 4 in the first ventilation pipe 3 can be adjusted according to the discharge situation of the storage bin 1, so that the height of the first branch pipe 31 used for communication with the storage bin 1 is basically the same as the material height in the storage bin 1 through the sealing block. In this way, the airflow generated by the dryer 2 can be used for ventilation and drying of the material in the storage bin 1 through the first ventilation holes on the pipe wall of the first branch pipe 31 without being wasted. Therefore, the storage device can improve the utilization rate of energy.

[0022] Specifically, since the first ventilation pipe 3 is divided into the first branch pipe 31 and the second branch pipe 32 which are not connected to each other by the sealing slider 4, and the first ventilation pipe 3 is connected to the interior of the storage bin 1 through the first ventilation hole opened on its pipe wall, therefore, by adjusting the sealing slider 4 to be substantially the same as the height of the current material in the storage bin 1, the sealing slider 4 can be used to block the wind flow entering the first ventilation pipe 3, so that all wind flows can enter the area for storing materials below the storage bin 1 through the first ventilation hole opened on the pipe wall of the first branch pipe 31, so as to ventilate and dry the current materials in the storage bin 1, and avoid the wind flow entering the idle space above the storage bin 1 through the first ventilation hole opened on the pipe wall of the second branch pipe 32 and causing waste. Therefore, the storage device disclosed in the present invention can improve the utilization rate of energy.

[0023] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 3As shown in , in order to uniformly control the sealing sliders 4 in each first ventilation pipe 3, the storage device may further include a transmission mechanism 6, and the driving member 5 is connected to the sealing slider 4 through the transmission mechanism 6; the transmission mechanism 6 may include a screw 64 and a nut 65 connected in a transmission manner, the screw 64 is connected to the driving member 5, and the sealing slider 4 is arranged on the nut 65, so that a plurality of screws 64 can be driven to rotate simultaneously by a driving member 5, thereby driving the nut 65 arranged on each screw 64 to move back and forth along the screw 64, and then driving the sealing slider 4 arranged on each nut 65 to move back and forth along the screw, thereby adjusting the length of the first branch pipe 31 and the second branch pipe 32 in each first ventilation pipe 3 according to the actual height of the material in the storage bin 1. Here, the nut 65 may be made of metal material, and the sealing slider 4 may be made of rubber material, and the sealing slider 4 is fixed on the nut 65 by bonding or welding, wherein the sealing slider 4 is used to cooperate with the first ventilation pipe 3, and the nut 65 is used to cooperate with the screw 64.

[0024] In addition, in order to improve the drying effect of the material, a plurality of first ventilation holes may be evenly spaced on the wall of the first ventilation pipe 3, so that all-round drying of the material can be achieved in the vertical and horizontal directions.

[0025] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 1 to 5 As shown in , the number of the first ventilation ducts 3 can be multiple, and each first ventilation duct 3 is provided with a lead screw 64 and a nut 65, wherein the driving member 5 can be constructed as a motor 51, and the transmission mechanism 6 can also include a driving wheel 61, a transmission belt 63 and a plurality of driven wheels 62, the motor 51 is arranged above the driving wheel 61 and is transmission-connected to the driving wheel 61, the driving wheel 61 is transmission-connected to the plurality of driven wheels 62 through transmission belts 63, wherein the driving wheel 61 and the plurality of driven wheels 62 are transmission-connected to the plurality of lead screws 64 one by one, respectively, so that when in use, the driving wheel 61 can be driven to rotate by the motor 51, and the driving wheel 61 then drives the driven wheel 62 to rotate through the transmission belt 63, thereby realizing the synchronous rotation of the driving wheel 61 and the driven wheel 62.

[0026] Among them, since the first ventilation pipes 3 include multiple ones, and each of the first ventilation pipes 3 is provided with a lead screw 64 and a nut 65 matched with the lead screw 64, and the lead screw 64 provided in one of the first ventilation pipes 3 is connected to the driving wheel 61 by transmission, and the lead screws 64 provided in the remaining first ventilation pipes 3 are connected to a driven wheel 62 by transmission, therefore, with the synchronous movement of the driving wheel 61 and the driven wheel 62, the lead screw 64 connected to the driving wheel 61 and the lead screw 64 connected to the driven wheel 62 can be driven to rotate synchronously, thereby driving the nut 65 provided in all the first ventilation pipes 3 to move upward or downward synchronously along the corresponding lead screw 64, thereby realizing the synchronous adjustment of the movement of the sealing sliders 4 provided in these first ventilation pipes 3. For ease of understanding, the above relationship will be further explained by examples below: Exemplarily, when the first ventilation ducts 3 include four as shown in the figure, a lead screw 64 and a nut 65 are correspondingly arranged in each first ventilation duct 3, and the driving wheel 61 includes one, and the driven wheels 62 include three, so that the driving wheel 61 is transmission-connected to a lead screw 64 in a first ventilation duct 3, and each driven wheel 62 is transmission-connected to each lead screw 64 in the remaining three first ventilation ducts 3.

[0027] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 5 to 7 As shown in , the storage device may also include a tensioning adjustment mechanism 7, which may include a tensioning wheel 71 and an actuating structure, wherein the tensioning wheel 71 abuts against the outer side of the transmission belt 63, and the actuating structure is used to drive the tensioning wheel 71 to move along the thickness direction of the transmission belt 63. Through such a setting, the tightness of the transmission belt 63 tensioned on the driving wheel 61 and the driven wheel 62 can be adjusted. In this way, when the transmission belt 63 is too loose, the braking structure can drive the tensioning wheel 71 to move toward the inner side of the transmission belt 63 along the thickness direction of the transmission belt 63 until it is adjusted to a suitable position; and when the transmission belt 63 is too tight, the braking structure can drive the tensioning wheel 71 to move toward the outer side of the transmission belt 63 along the thickness direction of the transmission belt 63 until it is adjusted to a suitable position, thereby realizing the adjustment of the tension of the transmission belt 63 to ensure that the transmission belt 63 can be transmitted reliably.

[0028] The braking structure may be a manual braking structure or an automatic braking structure, which may be flexibly selected according to actual conditions, and the present disclosure does not limit this. Figures 5 to 7As shown in , the actuating structure may also include a traction frame 72, an operating member 73 and a column 74. The column 74 is fixedly arranged on the storage bin 1 and is located on the inner side of the transmission belt 63. A through hole 741 and a threaded hole 742 are opened in the column 74 in a direction perpendicular to its own height. The traction frame 72 is slidably arranged in the through hole 741, and a tensioning wheel 71 is arranged at one end. The operating member 73 includes a screw rod 731, a stopper portion 732 and a hand-held portion 733. One end of the screw rod 731 passes through the other end of the traction frame 72 and is threadedly engaged with the threaded hole 742, and the other end of the screw rod 731 is provided with a hand-held portion 733, wherein the stopper portion 732 is arranged to protrude along the circumference of the screw rod 731 to limit the screw rod 731 from disengaging from the traction frame 72. In this way, when the tightness of the transmission belt 63 needs to be adjusted, the traction frame 72 can be driven by the operating member 73 to move toward the column 74 or away from the column 74 along the thickness direction of the tensioning wheel 71. The hand-held portion 733 and the stopper 732 can be constructed in any suitable manner, and the present disclosure does not limit this. Alternatively, the hand-held portion 733 can be constructed as a disc handle protruding along the circumference of the screw rod 731, and the stopper 732 can be constructed as a stopper disc protruding along the circumference of the screw rod 731.

[0029] Specifically, when the transmission belt 63 is too loose, the hand-held portion 733 can be used to adjust the screwing depth of the screw rod 731 and the threaded hole 742 on the column 74 to reduce the screwing depth. In this way, the screw rod 731 will drive the traction frame 72 to move along the extension direction of the through hole 741 on the column 74 through the stop portion 732, thereby driving the tensioning wheel 71 provided at one end of the traction frame 72 to move along the thickness direction of the transmission belt 63 toward the inner side of the transmission belt 63, thereby adjusting the tension of the transmission belt 63. When 63 is too tight, the hand-held portion 733 can be used to adjust the engagement depth of the screw rod 731 and the threaded hole 742 on the column 74 to increase the engagement depth. Afterwards, since the stop portion 732 is disengaged from the traction frame 72, it is necessary to manually push the traction frame 72 to move along the extension direction of the through hole 741 on the column 74 so that the tensioning wheel 71 arranged at one end of the traction frame 72 moves toward the outside of the transmission belt 63 along the thickness direction of the transmission belt 63, thereby achieving the adjustment of the tension of the transmission belt 63.

[0030] Therefore, it can be known from the above embodiments that the stop portion 732 in the operating member 73 is fixedly connected to the screw rod 731, but is not fixedly connected to the traction frame 72. Therefore, as the degree of engagement between the screw rod 731 and the threaded hole 742 decreases, the screw rod 731 will drive the traction frame 72 to move synchronously through the stop portion 732. Conversely, as the degree of engagement between the screw rod 731 and the threaded hole 742 increases, the screw rod 731 will drive the stop portion 732 to disengage from the stop engagement with the traction frame 72. At this time, manual operation is required to drive the traction frame 72 to move.

[0031] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 , Figure 2 as well as Figure 4 As shown in , in order to protect the driving member 5 and the transmission mechanism 6, the storage device may further include a protective cover 8, which is disposed above the driving member 5 and the transmission mechanism 6 and is fixedly connected to the column 74. In addition, in order to facilitate the maintenance of the driving member 5 and the transmission mechanism 6, the storage device may further include a ladder 9, wherein the ladder 9 is disposed on the side wall of the storage bin 1 along the height direction of the storage bin 1.

[0032] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 , Figure 2 as well as Figure 4 As shown in, the storage device may further include an air equalizing duct 10 arranged at the bottom of the storage bin 1, wherein the air equalizing duct 10 is constructed in an annular shape and is connected between multiple first ventilation ducts 3 and the air outlet, wherein the connection point between the air equalizing duct 10 and the air outlet is far away from the connection point between the air equalizing duct 10 and the first ventilation duct 3. Through such a configuration, before the airflow generated by the dryer 2 flows into the first ventilation duct 3, it will first enter the annular air equalizing duct 10 to be fully evenly distributed, and then enter the storage bin 1 through each first ventilation duct 3. In this way, it can be ensured that the airflow introduced by each first ventilation duct 3 is basically uniform, thereby achieving uniform ventilation and drying of the material in the storage bin 1, and avoiding uneven drying effects of materials in various places in the storage bin 1 due to the different sizes of airflows introduced into the storage bin 1 by each first ventilation duct 3.

[0033] The ring-shaped setting can reduce the flow resistance of the airflow in the air balancing duct 10, which is more conducive to improving the uniformity of the airflow. In addition, the connection between the air balancing duct 10 and the air outlet is far away from the connection between the air balancing duct 10 and the first ventilation duct 3. Such a design can ensure that the airflow can stay in the air balancing duct 10 and achieve the air balancing effect, and avoid the airflow directly passing through the air balancing duct 10 into the first ventilation duct 3.

[0034] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 and Figure 4As shown in the figure, the storage device may further include a second ventilation pipe 12, which is arranged in the storage bin 1 and extends in a direction perpendicular to the height direction of the storage bin 1, and the first ventilation pipe 3 is connected to the second ventilation pipe 12, wherein a second ventilation hole (not shown in the figure) is opened on the pipe wall of the second ventilation pipe 12, and the first ventilation pipe 3 is connected to the second ventilation pipe 12 through the first ventilation hole. Through such an arrangement, on the one hand, support for the first ventilation pipe 3 can be achieved to ensure that the first ventilation pipe 3 can be reliably fixed in the storage bin 1, and on the other hand, when the height of the material in the storage bin 1 is greater than the setting height of the second ventilation pipe 12, the second ventilation hole on the additional second ventilation pipe 12 can further make the airflow entering the storage bin 1 evenly distributed in the storage bin 1, thereby further improving the ventilation and drying effect of the storage bin 1.

[0035] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 , Figure 4 as well as Figure 8 As shown in the figure, in order to adjust the discharge volume of the storage bin 1 to achieve refined discharge, a discharge channel 13 can be provided at the bottom of the storage bin 1, and a discharge port 102 is formed at the bottom of the discharge channel 13. The discharge port 102 has a first side 1021 and a second side 1022 that are relatively arranged, and a first discharge baffle 14 is rotatably provided on the first side 1021, and a second discharge baffle 15 is rotatably provided on the second side 1022, wherein the first discharge baffle 14 and the second discharge baffle 15 rotate towards each other to adjust the size of the discharge port 102.

[0036] In the above embodiment, in order to facilitate the arrangement of the first discharge baffle 14 and the second discharge baffle 15, the discharge channel 13 can be designed as a square cylinder structure with a square cross section as shown in the figure. Adaptively, the discharge port 102 is constructed as a square port. In this case, one of the first discharge baffle 14 and the second discharge baffle 15 can be arranged on the first side 1021 of the square port, and the other can be arranged on the second side 1022 opposite to the first side 1021. In addition, in order to facilitate the discharge and avoid the interference between the first discharge baffle 14 and the second discharge baffle 15 during the rotation process, the first discharge baffle 14 and the second discharge baffle 15 can be arranged to be the same size and half the size of the discharge port 102. In this way, by controlling the first discharge baffle 14 and the second discharge baffle 15 to rotate towards each other at the same time, the size of the discharge port 102 can be adjusted, and the discharge port 102 can be closed when no discharge is needed.

[0037] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 8As shown in, in order to realize the automatic control of the opening and closing of the first discharge baffle 14 and the second discharge baffle 15, the storage device can be provided to further include a driving mechanism 16, and the driving mechanism 16 can include a pair of rotating shafts 161, a transmission rod 162, a slider 163 and an electric cylinder 164, and the pair of rotating shafts 161, the transmission rod 162 and the slider 163 are symmetrically arranged relative to the center line 1023 between the first side 1021 and the second side 1022, wherein the rotating shaft 161 is rotatably arranged on the first side 1021 or the second side 1022 and extending in a direction parallel to the center line 1023, one end of the first discharging baffle 14 or the second discharging baffle 15 is arranged on the rotating shaft 161, the rotating shaft 161 is connected with a transmission rod 162, a slide groove 1621 is provided on the transmission rod 162 along its length direction, a slider 163 is slidably arranged in the slide groove 1621, and the two sliders 163 are both connected to the electric cylinder 164, and the electric cylinder 164 is used to drive the two sliders 163 to move in the vertical direction, so as to drive the two rotating shafts 161 to rotate through the two transmission rods 162. Among them, the electric cylinder 164 is telescopic in the vertical direction, and the electric cylinder 164 is respectively connected to the two sliders 163 through a connecting member (such as a connecting block).

[0038] Through the above technical scheme, when it is necessary to control the opening and closing degree of the first discharge baffle 14 and the second discharge baffle 15, the electric cylinder 164 can be controlled to extend and retract in the vertical direction. In this way, the electric cylinder 164 will simultaneously drive the two sliders 163 to move in their respective slide grooves 1621 through the connecting piece, thereby driving the transmission rod 162 to rotate around the center of the rotating shaft 161, and at the same time driving the rotating shaft 161 to rotate around its own axis, thereby driving the first discharge baffle 14 or the second discharge baffle 15 set on the rotating shaft 161 to rotate, so that the size of the discharge port 102 can be adjusted.
