Description

Technical Field

[0001] This utility model relates to the field of polysilicon production technology, and in particular to a conveying device and a batching equipment. Background Technology

[0002] While current automated polysilicon packaging lines have automated the initial processes such as crushing, screening, and bagging, manual intervention is still required in the critical weighing and counterweighting stages. Operators must continuously perform three high-risk actions: ①. Real-time monitoring of the electronic scale reading (±0.2kg accuracy range) and calculation of the difference; ②. Frequently bending over to a 1.2m high work platform to grab bulk silicon material (each grabbing amount is about 50-200g); ③. Performing micro-feeding or material reduction operations in a confined work space. This not only results in high labor intensity for operators but also significant occupational health hazards (labor injury and electrostatic adsorption damage caused by excessive contact with silicon material). At the same time, the accuracy and efficiency of weighing are relatively low. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a conveying device and a batching equipment, which solves the technical problem that the existing polycrystalline silicon weighing and counterweighting process needs to be completed manually, which not only involves high labor intensity and health risks, but also has low accuracy and efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a conveying device on one side of the feeding unit. The conveying device, via a lifting mechanism, lowers the conveying carrier, allowing the material container to be fully supported by the weighing unit.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1-3 As shown in the figure, the present utility model application provides a conveying device, including a frame 1, a weighing unit 2, a conveying carrier 3 and a lifting mechanism 4.

[0038] Weighing unit 2 is mounted on frame 1 and is used to weigh materials. Conveying carrier 3 is movably mounted above frame 1 and is used to carry and transport material containers. Lifting mechanism 4 is driven to the conveying carrier 3, causing the conveying carrier 3 to move vertically up and down along the weighing unit 2, so that the material container is carried by the weighing unit 2 or by the conveying carrier 3, and can switch between the two states.

[0039] In use, after the lifting mechanism 4 lowers the conveying carrier 3, the material container is completely supported by the weighing unit 2. At this time, the material container is in a weighing state. When the weight reaches the preset value, the lifting mechanism 4 raises the conveying carrier 3, so that the material container contacts and is transferred to the conveying carrier 3. Through the above setting, not only can the material container be stably weighed on the weighing unit 2, but also, after the weighing is completed, the conveying carrier 3 can immediately transport the material container under the action of the lifting mechanism 4. This conveying device meets both the requirements of weighing and the requirements of material transportation, is convenient to use, and has high efficiency.

[0040] Furthermore, the conveying device also includes a control module, which is electrically connected to the weighing unit 2 and the lifting mechanism 4. The control module receives the detection signal from the weighing unit 2 and regulates the lifting action of the lifting mechanism 4.

[0041] The weighing unit 2 includes a support structure and a weighing sensor mounted on the support structure. The support structure is connected to the frame 1, and the weighing sensor is mounted on the support structure to detect the weight of the material in real time. The support structure includes multiple spaced support sections, and the conveying carrier 3 has clearance spaces adapted to the support sections, that is, the conveying carrier 3 has space to accommodate the support sections.

[0042] In this implementation scenario, the support structure includes multiple upright plates 21, and the support part is formed by multiple upright plates 21. There is at least one load cell, which is mounted on the upright plate 21. The output end of the load cell is electrically connected to the input end of the control module, and the output end of the control module is electrically connected to the input end of the lifting mechanism.

[0043] Optionally, the conveying carrier 3 may include, but is not limited to, rollers, belts, or chains. Preferably, the conveying carrier 3 is a conveying roller.

[0044] Optionally, the lifting mechanism 4 may include, but is not limited to, a cylinder.

[0045] In one implementation scenario, the conveying carrier 3 includes a mounting frame 31 and multiple rollers 32 rotatably disposed within the mounting frame 31. There is a gap between adjacent rollers 32, and a through groove 311 is provided at the bottom of the mounting frame 31 corresponding to this gap. A vertical plate 21 passes through the through groove 311 and is fixedly connected at one end to the frame 1. That is, the gap between adjacent rollers 32 and the through groove 311 together form a clearance space, and the vertical plate 21 is located within this clearance space. For example, five vertical plates 21 are used, distributed between two adjacent rollers 32, and the lower end of each vertical plate 21 is connected to the top of the frame 1 after passing through the through groove 311.

[0046] Optionally, the lifting mechanism 4 is installed on the horizontal plate of the frame 1, and its movable end is connected to the bottom of the mounting frame 31. The mounting frame 31 can move up or down under the drive of the lifting mechanism 4.

[0047] As one method of use: The weighing unit 2 corresponds to the outlet of the feeding device. A material container (box) for receiving silicon material is placed on the weighing unit 2. At this time (in the initial state), the bottom of the mounting frame 31 is close to the upper surface of the frame 1, and the upper ends of the multiple vertical plates 21 protrude from the upper surface of the conveying carrier 3. The material container is completely supported by the weighing unit 2. The weight sensor detects the weight of the material and transmits the detection signal to the control module. When the weight in the material container reaches the preset value, the control module regulates the lifting mechanism 4 to rise. At this time, the bottom of the mounting frame 31 is away from the upper surface of the frame 1, and the upper ends of the multiple vertical plates 21 are located in the gap or through groove between the rollers 32, so that the material container comes into contact with the conveying carrier 3 and is transferred through it.

[0048] Example 2

[0049] like Figures 4-8 As shown in the figure, this utility model application provides a batching device, including a conveying device 100 and a feeding device 200.

[0050] The conveying device 100 is located at the outlet end of the feeding device 200, and the conveying device 100 is the conveying device described in Embodiment 1. In use, the weighing unit 2 is aligned with the outlet of the feeding device 200.

[0051] In one embodiment, the feeding device 200 includes: a hopper 5, a graded conveying structure 6, and a vibration device 7.

[0052] The graded conveying structure 6 has an inlet 61 and an outlet 62. The inlet 61 of the graded conveying structure 6 is connected to the outlet of the hopper 5, and the outlet 62 corresponds to the weighing unit 2 of the conveying device 100. A vibration device 7 is installed below the graded conveying structure 6 to generate vibration on the graded conveying structure 6.

[0053] Optionally, the graded conveying structure 6 includes, sequentially from one end of the hopper 5, a feeding section 6a, an inclined section 6b, a horizontal section 6c, and a discharging section 6d. The feeding section 6a is horizontally positioned, the horizontal section 6c is positioned lower than the feeding section 6a, the inclined section 6b is inclined downwards from one end of the feeding section 6a towards the horizontal section 6c, and the discharging section 6d is inclined downwards from one end of the horizontal section 6c, with the lower inclined end of the discharging section 6d facing the weighing unit 2. Considering the flow characteristics of polycrystalline silicon particles, the graded conveying structure 6 can prevent material blockage or overfeeding.

[0054] Optionally, a vibration device 7 is provided below the feeding section 6a and the horizontal section 6c respectively.

[0055] Optionally, the feed inlet 61 is opened on the upper surface of the feed section 6a, and the hopper 5 has an extension 51 extending into the feed inlet 61 at its lower end.

[0056] Optionally, the hopper 5 and / or the graded conveying structure 6 are provided with an antistatic coating, which can effectively reduce the adsorption of polycrystalline silicon particles.

[0057] In one embodiment, the feeding device 200 further includes a housing 8 and a dust collection system. The graded conveying structure 6 and the vibration device 7 are both disposed inside the housing 8. The dust collection system is connected to the internal cavity of the housing 8 and is used to collect dust and prevent dust leakage. For example, the dust collection system includes an exhaust fan. The input end of the exhaust fan is connected to the inside of the housing 8 through a pipe 9, and the output end of the exhaust fan is connected to the dust collection device. In use, under the action of the exhaust fan, the dust inside the housing 8 is drawn into the dust collection device for collection.

[0058] As one method of use: Polycrystalline silicon material is fed into the hopper 5, and falls through the extension section 51 into the feeding section 6a of the graded conveying structure 6. Under the action of the vibration device, it passes sequentially through the inclined section 6b, the horizontal section 6c, and the discharge section 6d before falling into the material container (box) placed on the weighing unit 2. At this time, the weight sensor detects the weight of the material in real time and transmits the detection signal to the control module. When the weight in the material container reaches the preset value, the control module regulates the lifting mechanism 4 to rise, so that the material container contacts the conveying carrier 3 for transmission. Feeding, weighing, and transmission are all intelligently controlled by the control module, which not only realizes the automatic feeding and counterweight function and improves the degree of automation, but also effectively reduces the counterweight error compared to frequent manual operation.

[0059] It should be noted that neither the weighing sensor nor the control module is shown in the diagram of this utility model. The weighing sensor can be an existing high-precision weighing sensor (accuracy ±0.1g). The control module can be a PLC controller, which can receive weighing data in real time. For example, when the weight in the material container reaches 10kg, feeding will stop immediately (the feeding system can control the raw material flow through a double-screw feeder (coarse adjustment + fine adjustment mode). In the coarse adjustment stage, the material is quickly filled to 9.5kg, and in the fine adjustment stage, the material is replenished to reach the target value of 10kg; the PLC controller receives weighing data in real time, and after the material is fed to 10kg in the fine adjustment stage, it is automatically conveyed to the next stage of packaging).

[0060] Any aspects not described in detail in this embodiment are techniques known in the art.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
