Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment for soy sauce brewing, specifically a slag bin and a soy sauce slag conveying system with a slag bin. Background Technology

[0002] During soy sauce production, soy sauce residue is generated. Since soy sauce production is a continuous or batch process, the subsequent handling of the residue (such as transportation and processing) is not always synchronized with production. Therefore, a buffer zone is needed between soy sauce production and residue handling. Typically, soy sauce production plants have residue bins to collect and store this residue. Once a predetermined amount has accumulated in the bins, the residue is transferred to transport equipment for further processing.

[0003] In existing technologies, augers are typically installed at the discharge port of the slag bin to push the sauce residue out of the bin. However, sauce residue is generally flaky and contains a certain amount of moisture. When it accumulates in the slag bin, it easily forms clumps, causing blockage at the bin outlet. Furthermore, because slag bins are usually designed to be wider at the top and narrower at the bottom, the sauce residue may also bridge above the auger, preventing it from contacting the auger and causing the residue to fail to discharge. Using multiple augers for sauce residue discharge would increase energy consumption and thus raise the cost of sauce residue processing. Utility Model Content

[0004] To address the above problems, this utility model provides a slag bin that can quickly and conveniently transfer sauce residue from the bin to a transport device without using an auger.

[0005] The first aspect of this utility model provides a slag bin for storing sauce residue. The slag bin includes a bin body, a bin door, and a drive unit. The bin body has a lower opening. The bin door includes a door body and a connecting part, which is rotatably connected to the bin body. The rotation stroke of the door body includes a first position located on the side of the bin body and a second position covering and closing the lower opening. The drive unit is fixedly connected to the bin body, and the output end of the drive unit is connected to the bin door to drive the rotation of the door body.

[0006] Optionally, the container body is a cuboid, and the container body also includes an upper opening, the upper opening and the lower opening having the same surface area.

[0007] Optionally, the slag bin also includes a frame structure, which is fixedly installed on the outer surface of the bin body and the door. The frame structure includes multiple crossbeams, with drive units installed at both ends of two of the crossbeams.

[0008] Optionally, the drive unit is a hydraulic cylinder.

[0009] Optionally, the warehouse doors include a first warehouse door and a second warehouse door that are symmetrically arranged with the same shape and size, and the cross-sectional shape of the warehouse doors is fan-shaped.

[0010] Optionally, the output end of the drive unit is connected to the position of the door located between the door body and the door body's rotation axis.

[0011] Optionally, the hydraulic cylinder includes a cylinder liner and a piston rod, the piston rod is movably connected to the cylinder liner, and the piston rod can extend and retract inside and outside the cylinder liner, with one end of the piston rod connected to the door.

[0012] Optionally, a second aspect of this utility model provides a sauce residue conveying system having the aforementioned residue bin.

[0013] Optionally, the sauce residue conveying system also includes a transport vehicle that can be moved below the residue bin to receive the sauce residue sent out through the lower opening. The transport vehicle includes a bucket with an upper surface area greater than half the surface area of ​​the lower opening.

[0014] This invention provides a slag bin for storing sauce residue. When the sauce residue from different batches accumulates to the preset capacity of the bin or reaches the designated processing date, the bottom door of the bin is opened by a drive unit, allowing the accumulated residue to fall naturally under its own weight and be discharged from the bottom opening of the bin. This invention eliminates the need for an auger and effectively avoids problems such as bridging of residue within the bin or blockage at the discharge port, greatly simplifying the bin structure and reducing energy consumption.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During the soy sauce brewing process, a certain amount of solid soy sauce residue is usually generated. This residue can be processed professionally and then transported to agricultural and industrial sectors for secondary use. Therefore, the residue separated from the soy sauce production line needs to be properly collected and stored; otherwise, it will cause a messy production environment and affect normal soy sauce brewing. To address this, the first aspect of this invention provides a residue bin 100 for the centralized collection and storage of the aforementioned residue, facilitating centralized subsequent processing and secondary utilization.

[0020] In this embodiment, the slag bin 100 includes a bin body 1, a bin door 2, and a drive unit 3. (See reference) Figure 1 The silo 1 has a lower opening 11 located at the bottom, through which the sauce residue stored in the silo 1 can be discharged to the outside of the silo 1. Additionally, the silo 1 also includes an upper opening 12 at the top. After the sauce residue is separated from the production line and transferred to the residue silo 100, it can be poured into the silo 1 through the upper opening 12 for temporary storage. When the sauce residue from different batches accumulates to the preset capacity of the silo 1 or reaches the designated sauce residue processing date, the sauce residue in the silo 1 will be discharged from the lower opening 11 and transferred to other processes for further processing.

[0021] In existing technology, the bottom discharge port of the slag bin 100 is usually equipped with an auger to convey the soy sauce residue inside the bin 1 outward. To facilitate the use of the auger, the bin 1 is usually wider at the top and narrower at the bottom, allowing the soy sauce residue to accumulate more concentratedly on the auger blades. However, since most of the soy sauce residue separated in the soy sauce production line is flaky and contains a certain amount of moisture, when the internal structure of the bin 1 is designed to be wider at the top and narrower at the bottom, friction and adhesion may cause the soy sauce residue to form bridges in the bin 1 due to friction and adhesion. This can lead to the soy sauce residue clumping and blocking inside the bin 1, preventing it from falling smoothly out of the bin 1.

[0022] Therefore, in this embodiment, to avoid bridging of sauce residue within the storage chamber 1, the storage chamber 1 is designed as a cuboid, with the upper opening 12 and lower opening 11 having the same surface area, and the inner wall of the storage chamber 1 arranged along the direction of gravity. When the sauce residue accumulated in the storage chamber 1 needs to be discharged, the frictional and supporting forces provided by the inner wall of the storage chamber 1 to the sauce residue are relatively small, making it difficult to support the weight of the sauce residue itself, allowing the sauce residue to fall vertically from the lower opening 11 and be discharged from the storage chamber 1 smoothly.

[0023] In this embodiment, the silo door 2 is located below the slag silo 100, and includes a door body 21 and a connecting part 22, as shown in the reference. Figure 1The connecting part 22 is rotatably connected to the silo body 1, allowing the door 21 to pivot about the connection point between the connecting part 22 and the silo body 1 as the rotation axis 221. The silo door 2 includes a door body 21 and a connecting part 22, which is rotatably connected to the silo body 1. Specifically, the rotation stroke of the door body 21 includes a first position located on the side of the silo body 1, and a second position covering and closing the lower opening 11. To enable the door body 21 to reciprocate between the first and second positions, the slag silo 100 is also provided with a drive part 3, which is fixedly connected to the silo body 1. The output end of the drive part 3 is connected to the silo door 2 to drive the rotation of the door body 21. In this embodiment, to enable the drive unit 3 to provide more sufficient driving force to the door 2, the drive unit 3 is a hydraulic cylinder, which can be uniformly controlled by a hydraulic station (not shown in the figure). Specifically, the hydraulic cylinder includes a cylinder liner 31 and a piston rod 32. When the door 2 switches between the first position and the second position, in order to save the driving force required by the hydraulic cylinder and extend the service life of the hydraulic cylinder, refer to... Figure 1 The output end of the hydraulic cylinder, i.e., one end of the piston rod 32, is connected to the position of the door 2 between the door body 21 and the rotation shaft 221 of the door body 21. When the hydraulic cylinder is activated, causing its piston rod 32 to retract into the cylinder sleeve 31, the piston rod 32 pulls the door body 21 to rotate to the first position, and the lower opening 11 of the compartment 1 is opened. At this time, the soy sauce residue in the compartment 1, having lost the upward support of the door body 21, will pass through the lower opening 11 of the compartment 1 and be discharged from the inside of the compartment 1 under its own gravity. When the piston rod 32 is extended from the cylinder sleeve 31, the piston rod 32 pushes the door 2 to rotate to the second position, causing the door body 21 to cover and close the lower opening 11 again. At this time, newly generated soy sauce residue from the soy sauce production line can continue to be poured into the compartment 1.

[0024] In this embodiment, the surface of the silo body 1 is further provided with a frame structure 4, which includes multiple horizontal beams 41 and vertical beams 42. This frame structure 4 can be used to reinforce the silo body 1 and improve its load-bearing capacity for soy sauce residue. (Reference) Figure 1 and Figure 2 Two crossbeams 41 are perpendicular to the height of the silo body 1 and extend slightly beyond the outer surface of the silo body 1. Drive units 3 are installed at both ends of the two crossbeams 41. Specifically, the bottom of the cylinder liner 31 of the hydraulic cylinder is fixedly connected to the end of the crossbeam 41.

[0025] The second aspect of this utility model provides a sauce residue conveying system, which includes the aforementioned residue bin 100. In order to transfer the sauce residue temporarily stored in the bin 1 to other processes, the sauce residue conveying system also includes a transport vehicle (not shown in the figure). When the sauce residue produced by different batches in the bin 1 accumulates to the preset capacity of the bin 1 or reaches the specified sauce residue processing date, the transport vehicle can be moved to the bottom of the residue bin 100, and the upper surface of the transport vehicle's bucket (not shown in the figure) is aligned with the lower opening 11 of the bin 1 to receive the sauce residue sent out through the lower opening 11.

[0026] To maximize the storage capacity of soy sauce residue generated during production, the silo body 1 is typically large. However, a larger silo body 1 results in two issues: firstly, increased weight of the residue necessitates a stronger load-bearing capacity for the silo door 2; secondly, a larger surface area for the lower opening 11. Since the upper surface area of ​​the transport vehicle's cargo bed is usually limited to a certain size to ensure maneuverability during transport, the surface area of ​​the lower opening 11 is generally larger than that of the transport vehicle's cargo bed. When the residue necessitates being poured from the silo body 1 into the transport vehicle's cargo bed, opening the silo door 2 completely would cause some residue to fall outside the cargo bed, contaminating the production workshop floor and affecting normal soy sauce production. Therefore, in this embodiment, the silo door 2 includes a first door 2A and a second door 2B of identical shape and size, symmetrically arranged. The first door 2A and the second door 2B each cover half of the surface area of ​​the lower opening 11. (Reference) Figure 1 and Figure 2 The first compartment door 2A and the second compartment door 2B both have a fan-shaped cross-section, and the middle positions of the front and rear fan-shaped surfaces of each compartment door 2 are respectively connected to hydraulic cylinders. In this embodiment, all the hydraulic cylinders connected to the compartment doors 2 can be controlled by a single hydraulic station (not shown in the figure) for extension and retraction, and the drive commands to different hydraulic cylinders are independent of each other, so that the rotation of the first compartment door 2A and the second compartment door 2B can also be independent of each other.

[0027] By dividing the storage door 2 into a first storage door 2A and a second storage door 2B, the weight of the sauce residue inside the storage body 1 can be evenly distributed on the inner surfaces of the door bodies 21 of the first and second storage doors 2A and 2B facing the storage body 1, thereby increasing the load-bearing capacity of the storage body 1 for sauce residue to a certain extent. On the other hand, in this embodiment, the surface area of ​​the truck bed is greater than half the surface area of ​​the lower opening 11. By individually driving the first storage door 2A or the second storage door 2B to rotate from the second position to the first position, the area where sauce residue falls inside the storage body 1 is only half the surface area of ​​the lower opening 11, which can greatly reduce the possibility of sauce residue falling outside the truck bed. The specific steps for discharging the sauce residue from silo 1 into the truck bed of the transport vehicle are as follows: When the sauce residue from different batches in silo 1 accumulates to the preset capacity of silo 1 or reaches the designated sauce residue processing date, the sauce residue in silo 1 needs to be discharged from the lower opening 11. The transport vehicle can be moved in advance to below the residue bin 100, so that the upper surface of the truck bed is directly below the door 21 of the first silo door 2A in the second position. Then, the hydraulic cylinder connected to the first silo door 2A is activated. By retracting the piston rod 32 into the cylinder sleeve 31, the door 21 of the first silo door 2A above the truck bed is rotated to the first position, while keeping the position of the second silo door 2B unchanged, so that it continues to cover the lower opening 11 of silo 1. At this time, the sauce residue in silo 1 will pass through the opened part of the lower opening 11 and fall into the truck bed directly below. Once the sauce residue in the truck bed has reached the predetermined volume or when no more sauce residue falls from the bin 1, the hydraulic cylinder connected to the first bin door 2A is activated again, causing its piston rod 32 to extend out of the cylinder sleeve 31, pushing the first bin door 2A from its first position back to the second position. After the lower opening 11 is completely covered again, the transport vehicle, along with the sauce residue in the truck bed, is transferred to the next process for sauce residue processing. Since there may still be accumulated sauce residue above the door 21 of the second bin door 2B, the transport vehicle can be moved again below the slag bin 100, so that the upper surface of the truck bed is directly below the door 21 of the second bin door 2B in its second position. Then, the hydraulic cylinder connected to the second bin door 2B is activated, and by retracting the piston rod 32 into the cylinder sleeve 31, the door 21 of the second bin door 2B above the truck bed is rotated to the first position, while keeping the first bin door 2A in its current position, so that it continues to cover the lower opening 11 of the bin 1. At this point, the remaining sauce residue in compartment 1 continues to fall into the truck bed of the transport vehicle. Once the sauce residue in the truck bed has reached the predetermined volume, or when no more sauce residue falls from compartment 1, the hydraulic cylinder connected to the second compartment door 2B is activated, causing its piston rod 32 to extend again from the cylinder sleeve 31. This pushes the second compartment door 2B, which was in the first position, back to the second position. After the lower opening 11 is completely covered again, the remaining sauce residue is transferred to the next process for sauce residue treatment. If, after the above steps, there is still residual sauce residue in compartment 1 that has not been completely discharged, the steps of opening the first compartment door 2A and the second compartment door 2B in sequence can be repeated until all the sauce residue is poured out.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
