Description

Technical Field

[0001] This utility model relates to the technical field of equipment for particleboard production, and in particular to a large particleboard buffer silo. Background Technology

[0002] Particleboard, also known as chipboard, is a type of engineered wood product made by cutting various branches, small-diameter timber, fast-growing wood, and wood chips into fragments of a certain size, drying them, mixing them with adhesives, hardeners, and waterproofing agents, and then pressing them under specific temperature and pressure conditions. After the raw materials are cut into fragments, they are typically fed into a silo for buffering or temporary storage. However, the material is difficult to mix evenly between the silo and the outlet, resulting in particleboard with poor strength consistency when used directly. Furthermore, transferring the material from the silo to the particleboard production line requires a screw or scraper conveyor system, which results in uneven material distribution, hindering the formation of particleboard with consistent thickness. While rectangular silos have been used to alleviate these technical problems, their ability to evenly mix the material is limited, and the location of the outlet makes them prone to clogging due to insufficient power during discharge, failing to solve the problem of uniform material distribution. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a shavings buffer silo that helps to improve the uniform mixing ability and effect of materials in the silo, and provides sufficient and uniform discharge power.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a shavings buffer silo, including a box-type silo body, a chain rake mechanism installed at the top of the silo body, a loosening conveying mechanism installed at the bottom of the silo body, an inlet opening through the top wall of the silo body, a staggered material distribution plate fixedly installed in the silo body corresponding to the inlet, and the staggered material distribution plate is disposed through the chain rake mechanism, a bulk material output mechanism for cooperation is provided in the silo body at the discharge end of the loosening conveying mechanism, and a discharge port is provided through the bottom wall of the silo body corresponding to the discharge end of the bulk material output mechanism.

[0005] As a preferred technical solution, the staggered material distribution plate includes a material receiving part fixedly connected between the two inner walls of the silo body, and a staggered material dropping part is fixedly connected to one end of the material receiving part facing the bulk material output mechanism, and the staggered material dropping part is gradually narrowed from the material receiving part towards the bulk material output mechanism.

[0006] As a preferred technical solution, the material receiving part is configured as a rectangular structure, and the staggered material dropping part is configured as a triangular or trapezoidal structure.

[0007] As a preferred technical solution, the bulk material output mechanism includes an inclined bulk material output frame, on which a bulk material output roller is rotatably mounted. Each of the bulk material output rollers is radially arranged with a bulk material output deflector. One end of each bulk material output roller extends to the outside of the hopper body and is rotatably assembled with the hopper body. The end of the bulk material output roller located on the outside of the hopper body is connected to a bulk material output motor, and the power of at least the bottom bulk material output motor is greater than the power of the other bulk material output motors above it.

[0008] As a preferred technical solution, the power of each of the bulk material output motors is set to gradually increase from top to bottom.

[0009] As a preferred technical solution, the width of at least the bottom material output deflector is greater than the width of the other material output deflectors above it.

[0010] As an improvement to the above technical solution, the width of each of the bulk material output deflectors is gradually widened from top to bottom.

[0011] Due to the adoption of the above technical solution, the particleboard buffer silo includes a box-type silo body. A chain-type rake mechanism is installed at the top of the silo body, and a loosening conveying mechanism is installed at the bottom of the silo body. An inlet is provided through the top wall of the silo body. A staggered-time distribution plate is fixedly installed inside the silo body corresponding to the inlet, and the staggered-time distribution plate passes through the chain-type rake mechanism. A cooperating bulk material output mechanism is provided at the discharge end of the loosening conveying mechanism inside the silo body, and an outlet is provided through the bottom wall of the silo body corresponding to the discharge end of the bulk material output mechanism. The present invention has the following beneficial effects: the material fed in through the feed inlet is first temporarily received by the staggered feeding plate. As the chain rake mechanism moves forward, the material is gradually rake-pushed from the staggered feeding plate into the silo body. The material will form a mixing effect during the rake-pushing process, and will also form a mixing effect when falling into the silo body. This unloading method will cause the material on the side of the silo near the bulk material output mechanism to pile up. When the pile reaches a certain height, it can contact the chain rake mechanism and be rake-pushed to the other side of the silo body with the help of the chain rake mechanism, which can further mix the material and significantly improve the mixing degree and effect of the material.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figures 1 to 6 As shown, the large particleboard buffer silo is used to store materials for particleboard production. It allows for multiple mixing processes from material entry to exit, thereby improving mixing capacity and effectiveness, and ensuring material uniformity during particleboard formation. The large particleboard buffer silo includes a rectangular box-shaped silo body 1, typically over five meters in length, with a large capacity. For ease of inspection and maintenance, a safety ladder 2 can be installed on the outside of the silo body 1.

[0022] A chain-type rake mechanism 3 is installed at the top of the interior of the silo body 1, and a loosening conveying mechanism 4 is installed at the bottom of the interior of the silo body 1. An inlet 5 is provided through the top wall of the silo body 1. Material is fed into the silo body 1 through the inlet 5. The chain-type rake mechanism 3 is used to rake and mix the material in the silo, so that the silo body 1 can accommodate the material to the maximum extent. The chain-type rake mechanism 3 generally includes rake rollers arranged opposite each other, a chain-type rake belt sleeved between the two rake rollers, and a rake motor that drives one of the rake rollers to rotate. Rake teeth are arranged on the chain-type rake belt. Driven by the rake motor, the two rake rollers rotate, causing the chain-type rake belt to rotate cyclically. During this process, the rake teeth level the piled material in the silo, ensuring that material is distributed at both ends of the silo body 1. The loosening conveying mechanism 4 is a slow-moving conveyor belt mechanism to assist in material discharge. The chain-type rake mechanism 3 and the loosening and conveying mechanism 4 are both well known to those skilled in the art and will not be described in detail here.

[0023] In this embodiment, a staggered material distribution plate 6 is fixedly installed inside the silo body 1 corresponding to the feed inlet 5, and the staggered material distribution plate 6 is disposed through the chain rake mechanism 3. In fact, the staggered material distribution plate 6 passes through the reciprocating chain rake belt. When material is fed in through the feed inlet 5, it will first fall on the staggered material distribution plate 6, and due to the characteristics of free fall of material, it is easy to accumulate in a pile on the staggered material distribution plate 6. The silo body 1 is provided with a bulk material output mechanism at the discharge end of the loose material conveying mechanism 4, and a discharge port 11 is provided through the bottom wall of the silo body 1 corresponding to the discharge end of the bulk material output mechanism.

[0024] Specifically, the staggered material distribution plate 6 includes a material receiving part 61 fixedly connected between the two inner walls of the hopper body 1. The material receiving part 61 is configured as a rectangular structure. A staggered material dropping part 62 is fixedly connected to one end of the material receiving part 61 facing the bulk material output mechanism. The staggered material dropping part 62 is gradually narrowed from the material receiving part 61 towards the bulk material output mechanism. The staggered material dropping part 62 is configured as a triangular structure or a trapezoidal structure. When the material is fed in, it accumulates on the material receiving part 61. During the process of the material being fed into the accumulation part, there is actually an initial mixing of the material. During the circulation of the chain rake belt, each rake tooth will contact the material pile in turn and break it up to form a second mixing of the material. At the same time, the rake teeth will also drive the material forward. When the material moves to the staggered dropping part 62, due to the gradually changing width of the staggered dropping part 62, the gap between its two sides and the inner wall of the hopper body 1 becomes larger and larger. The material will gradually fall into the hopper body 1 from the gaps on both sides and form a third mixing of the material. When the material falls into the hopper body 1, it will also form a material pile. After it reaches a certain height, it will contact the circulating chain rake belt. The rake teeth can sweep the other side of the hopper body 1, which will form a fourth mixing of the material.

[0025] Specifically, the bulk material output mechanism includes an inclined bulk material output frame 7, on which bulk material output rollers 8 are rotatably mounted. Bulk material output deflectors 9 are radially arranged on each of the bulk material output rollers 8. One end of each bulk material output roller 8 extends to the outside of the hopper body 1 and is rotatably assembled with it. A bulk material output motor 10 is drively connected to the end of the bulk material output roller 8 located outside the hopper body 1. At least the bottom bulk material output motor 10 has a higher power than the other top bulk material output motors 10. In this embodiment, the power of the two bottom bulk material output motors 10 is increased. Due to the gravity effect of the accumulated material, the material at the bottom experiences greater force and greater discharge resistance. Increasing the power of the bottom bulk material output motors 10 ensures sufficient material-pulling power at the bottom, allowing all the bulk material output deflectors 9 to discharge material. Of course, the power of each of the bulk material output motors 10 can be set to gradually increase from top to bottom, which can also achieve the effect of sufficient discharge power and good discharge consistency. During the discharge process, the slow operation of the loosening conveying mechanism 4 can loosen the material, which is more conducive to smooth discharge. Moreover, during discharge, the layered arrangement of the bulk material output rollers 8 in terms of height, in cooperation with the loosening conveying mechanism 4, realizes automatic discharge, and a fifth mixing of materials can be formed during the discharge process.

[0026] Due to the high-power bulk material output motor 10, the width of the bulk material output deflector 9 at the bottom is greater than the width of the other bulk material output deflectors 9 above it, corresponding to the two high-power bulk material output motors 10 in this embodiment. The two bottommost bulk material output deflectors 9 are also wider. Of course, when the power of each bulk material output motor 10 gradually increases from top to bottom, the width of each bulk material output deflector 9 should also gradually increase from top to bottom to appropriately match the bulk material output motor 10 and achieve efficient and uniform material output.

[0027] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
