Description

Technical Field

[0001] This utility model relates to the field of industrial silicon raw material processing technology, and specifically to an incoming processing system for industrial silicon raw materials. Background Technology

[0002] In the production process of industrial silicon (also known as metallic silicon or crystalline silicon), the unloading, storage, batching and feeding of raw materials generally suffer from problems such as low efficiency, high safety risks and high operating costs.

[0003] Specifically, after raw materials (silica, washed coal, wood chips, etc.) are transported to the production site by truck, most companies use closed warehouses to store them to keep them dry. However, some companies still use open-air storage methods, which makes the raw materials susceptible to environmental influences. In addition, the storage of coal poses a risk of spontaneous combustion.

[0004] Although the batching process uses an automated system, it still relies on manual loader feeding, resulting in low efficiency, high operational safety risks, and rising labor and equipment maintenance costs. In the feeding process, after the mixed material is conveyed to the top silo of the electric arc furnace by belt conveyor, the furnace operator needs to remotely control the vibratory feeder to add material, indicating insufficient overall automation.

[0005] The above process involves frequent manual intervention, significant safety hazards (such as the risk of spontaneous combustion and mechanical injury), and high costs. There is an urgent need for a fully automated solution covering the entire process from raw material unloading, storage, batching to loading, in order to improve the efficiency, safety, and economy of industrial silicon production.

[0055] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0056] Example:

[0057] See Figure 1 This embodiment discloses an inbound processing system for industrial silicon raw materials, including an unloading unit 10, a screening and washing unit 20, a storage unit 30, a feeding unit 40, and a belt conveyor network 50. The unloading unit 10 guides vehicles to corresponding unloading areas based on their cargo information, with each unloading area corresponding to a different type of cargo. Each unloading area is equipped with an unloading platform 11, which tilts the vehicle, causing the cargo inside to spill onto the belt conveyor network 50. The belt conveyor network 50 then transports the different cargoes to the screening and washing unit 20 or the storage unit 30.

[0058] The screening and washing unit 20 is used to process silica and wood chips. The clean coal is directly transported to the storage unit 30. The silica and wood chips processed by the screening and washing unit 20 are also transported to the storage unit 30 for storage.

[0059] The storage unit 30 includes at least three storage areas, each capable of storing silica, wood chips, and refined coal separately.

[0060] The feeding unit 40 is used to feed silica, coking coal and wood chips onto the mixing belt in proportions required by the process. The output end of the mixing belt is located in the furnace top silo in the workshop.

[0061] In this embodiment, the unloading unit 10 guides the vehicle loaded with raw materials to the designated unloading area, and the unloading platform 11 automatically unloads the goods. Then, the goods are transported to the screening, washing unit 20 or storage unit via the belt network 50. Finally, the goods are delivered to the workshop via the feeding unit 40. The entire process is highly automated, which can effectively improve efficiency and reduce safety risks.

[0062] In one specific embodiment:

[0063] The unloading unit 10 includes an information input module 12 and a visual guidance module 13. The information input module 12 is used to record vehicle license plate information and cargo information carried by the vehicle, and the visual guidance module 13 is used to guide the vehicle to the corresponding unloading area.

[0064] Specifically, information entry equipment is set up at the gate of the site, such as a computer connected to a license plate recognition camera. When a truck is detected entering the site, a person (usually a gatekeeper) selects the type of raw materials carried by the vehicle, thereby completing the information entry.

[0065] The visual guidance module 13 includes multiple monitoring devices, each with a built-in voice broadcast module. Multiple monitoring devices are installed on the roads leading from the site entrance to all unloading areas. The voice broadcast module guides vehicles to their designated unloading areas based on license plate information identified by the monitoring devices.

[0066] In addition, the visual guidance module 13 can also be multiple variable guidance signs composed of light-emitting diodes set at key intersections, which change the directional arrows according to the vehicle license plate information, thereby guiding the vehicle to the corresponding unloading area.

[0067] The unloading platform 11 includes a drive mechanism and a hydraulic drive assembly. The drive mechanism includes a support structure, and the hydraulic drive assembly includes a hydraulic system that provides power and a telescopic structure that performs actions. The support structure is connected to the telescopic structure, and the telescopic structure drives the support structure to move in the vertical direction, thereby achieving the purpose of tilting the vehicle.

[0068] During operation, the telescopic structure drives the support structure (with the vehicle already on the support structure). Then, under hydraulic power, the support structure and the vehicle together tilt the front of the vehicle upwards by 0-55°, thereby unloading all the raw materials from the vehicle's cargo box. After unloading, the structure is reset.

[0069] The raw materials unloaded from the vehicle enter a hopper, and a belt network 50 is installed below the hopper. The belt network 50 transports silica and wood chip raw materials to the screening and washing unit 20, and transports clean coal raw materials to the storage unit 30. The belt network 50 refers to a conveyor belt structure that is connected by multiple conveyor belts and can transport materials over long distances.

[0070] The aforementioned screening and washing unit 20 includes a washing component 21, a screening component 22, and a homogenizing component. The washing component 21, screening component 22, and homogenizing component are located within the screening tower in the middle of the belt network 50 used for conveying silica.

[0071] The water washing assembly 21 includes multiple high-pressure water guns, which can rinse the silica and remove dirt and impurities from the silica surface. A sedimentation and recycling system is set below the high-pressure water guns to achieve the purpose of recycling water.

[0072] The screening component 22 is located below the washing component 21 and includes multiple vibrating screens. It separates coarse materials (large pieces of silica), fine materials (small pieces of silica and powder) and impurities according to the different aperture sizes of the screens on the vibrating screens.

[0073] The homogenization component is located downstream of the coarse material outlet of the screening component 22 and is equipped with a jaw crusher to crush the coarse material screened by the screening component 22 to the particle size required by the process.

[0074] Finally, the fine material screened by the screening component 22 and the silica that meets the requirements after being crushed by the homogenization component are returned to the belt network 50 and conveyed to the storage area for later use.

[0075] The storage area includes a silica silo 31 and a clean coal silo 32, an inert gas supply assembly, and a clean coal monitoring assembly. Since the clean coal is usually purchased directly, after the vehicles transporting the clean coal unload the clean coal in the unloading area, the clean coal falls through the hopper onto the belt network 50 used for transporting the clean coal and is directly transported to the clean coal silo 32 for storage.

[0076] The clean coal bin 32 is a closed structure. The inert gas supply component is used to input inert gas into the clean coal bin 32, usually nitrogen, to reduce the oxygen content in the clean coal bin 32 and form nitrogen inert protection to prevent the clean coal from spontaneously combusting.

[0077] Preferably, the inert gas supply assembly includes a nitrogen generator in the field area, which is connected to the inner wall of the coal bin 32 via a pipeline, and has multiple release holes arranged in a ring and evenly in the coal bin 32 for efficient and stable supply of nitrogen.

[0078] The clean coal monitoring component is located inside the clean coal silo 32. It includes a pressure sensor, an oxygen concentration sensor, and a temperature sensor to monitor the air pressure, oxygen concentration, and temperature inside the clean coal silo 32 in real time.

[0079] The aforementioned storage area also includes a wood chip bin 33, a spraying assembly, and a wood chip monitoring assembly. The vehicle transporting the wood chips travels to the unloading area, where the wood chips are unloaded into a hopper and fall onto a belt network 50 for transporting the wood chips, and then conveyed to the wood chip bin 33.

[0080] Both the spray system and the wood chip monitoring system are located inside the wood chip hopper 33. The spray system is situated at the top of the wood chip hopper 33 and can spray water downwards to increase the humidity of the wood chips. The wood chip monitoring system includes a temperature sensor and a humidity sensor to monitor the temperature and humidity of the wood chips in real time.

[0081] The spray system not only increases the humidity of the wood chips and inhibits spontaneous combustion, but also effectively reduces dust in the wood chip silo 33.

[0082] The feeding unit 40 includes a feeder and a weighing hopper. A feeder is provided in the wood chip bin 33, silica bin 31 and refined coal bin 32 respectively. The feeder is used to output silica, refined coal or wood chips. The weighing hopper is located at the output end of the feeder and is used to weigh silica, refined coal or wood chips.

[0083] Specifically, when the radar level gauge of the daily feed silo in the feeding unit 40 detects that the material level has reached the set safe level signal, the corresponding silos (coal silo 32, silica silo 31, and wood chip silo 33) receive a replenishment command and start the corresponding replenishment belts and feeders for discharging and replenishing. Among them, silica silo 31 is equipped with a vibrating feeder, coal silo 32 is equipped with a belt feeder, and wood chip silo 33 is equipped with a screw feeder. The feeders are frequency-controlled and the frequency is preset. Mid-process inspections or main control (monitoring inspection) are used to observe the situation and fine-tune the frequency to ensure stable operation.

[0084] When the radar level gauge in the reactor top hopper detects that the material level has reached the set safe level, the corresponding mixing belt of the feeding unit 40 receives the start command and starts the corresponding belt in a pre-set sequence. Silica, refined coal, and wood chips are discharged to the weighing hopper and metered and discharged to the mixing belt according to the set value. Each weighing hopper is equipped with 4 3200kg sensors (C6 accuracy, digital sensors).

[0085] First, the feeder of silica silo 31 starts feeding. When the mixed conveyor belt carrying silica runs to the bottom of clean coal silo 32, the clean coal feeder starts working. When the mixed conveyor belt carrying silica and clean coal runs to the bottom of wood chip silo 33, the feeder of wood chip silo 33 starts working.

[0086] The interval feeding time is preset according to the mixing belt speed and the hopper spacing. The frequency of each feeder is preset to control the thickness of the discharge layer and the length of the spreading material, so as to ensure that the material on the mixing belt is uniformly mixed.

[0087] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
