Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon production, in particular to a continuous pouring system for industrial silicon production. Background Art

[0002] At present, the pouring system of submerged arc furnace basically uses some relatively backward equipment with low automation. For example, when transferring and pouring silicon water bags, unpowered flat cars are used for human traction and transportation. Not only are there hazards such as silicon water splashing, scalding, high temperature, smoke and dust, and mechanical damage, but the production environment is relatively harsh, and production operators are in close or direct contact with equipment and products, which is prone to safety accidents. In addition, the high-load labor intensity and relatively poor working environment are prone to physical injuries.

[0003] Therefore, it is necessary for us to improve the continuity, systematicness and automation of the production process by optimizing the production equipment in the pouring process, and to solve practical problems such as low controllability of safety risks of the industrial silicon furnace pouring system, high labor intensity, low degree of automation, and loose process connection, so as to make the industrial silicon pre-furnace pouring production link more standardized, institutionalized and procedural, and create better production conditions for the smooth operation of the smelting production process and optimization of indicators of the ore-fired furnace. Utility Model Content

[0004] The utility model aims to disclose an industrial silicon production continuous pouring system to solve the problems of poor continuity of pouring production link, low production efficiency and loose connection between front and back processes in existing industrial silicon production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A continuous pouring system for industrial silicon production comprises silicon water bag transfer tracks arranged in parallel on both sides of the bottom of an ore-fired furnace, a silicon water bag transfer trolley is installed on the silicon water bag transfer tracks, and a silicon water bag is installed on the silicon water bag transfer trolley; a bag turner is installed at one end of the two silicon water bag transfer tracks away from the ore-fired furnace, an ingot mold transfer track perpendicular to the silicon water bag transfer track is arranged below the bag turner, an ingot mold transfer trolley is installed on the ingot mold transfer track, and a casting ingot mold is installed on the ingot mold transfer trolley.

[0007] It also includes an on-site PLC control cabinet and a monitoring camera. The on-site PLC control cabinet is respectively connected to the monitoring camera, the silicon water bag transfer trolley, the bag turning machine and the ingot mold transfer trolley by signals.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] After the improvement of the pouring system, the safety risks are effectively reduced. Personnel can remotely control the equipment to complete production links such as furnace unloading, pouring, and transfer. There is no need for close contact with high-temperature silicone water and high-temperature equipment, which effectively improves the working environment. Personnel do not need to work under high load, which reduces labor intensity. The connection between each process is smoother, which improves production efficiency and makes the operation of the entire production line more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0014] like Figure 1-2 As shown, a continuous pouring system for industrial silicon production includes silicon water bag transfer tracks 2 arranged in parallel on both sides of the bottom of a submerged arc furnace 1, silicon water bag transfer trolleys 3 are installed on the silicon water bag transfer tracks 2, and silicon water bags 4 are installed on the silicon water bag transfer trolleys 3; both ends of the two silicon water bag transfer tracks 2 away from the submerged arc furnace are installed with bag turning machines 5, and ingot mold transfer tracks 6 perpendicular to the silicon water bag transfer tracks 2 are arranged below the bag turning machines 5, ingot mold transfer tracks 6 are installed with ingot mold transfer trolleys 8, and casting ingot molds 9 are installed on the ingot mold transfer trolleys 8. It also includes an on-site PLC control cabinet 10 and a monitoring camera 7, and the on-site PLC control cabinet 10 is respectively connected to the silicon water bag transfer trolley 3, the bag turning machine 5, the ingot mold transfer trolley 8 and the monitoring camera 7 by signal.

[0015] The specific working process of the utility model is as follows:

[0016] During production, the operator first remotely controls a silicon water bag transfer trolley 3 on a silicon water bag transfer track 2 to the silicon outlet at the bottom of the ore-fired furnace 1 through the on-site PLC control cabinet 10. After the silicon is discharged, the silicon water bag transfer trolley 3 is remotely controlled to transfer the silicon water bag 4 filled with silicon water to the bag turning machine 5 at the end of the silicon water bag transfer track 2, and the ear shafts on both sides of the silicon water bag 4 are clamped into the grooves of the bag turning machine 5 by inertia. Then, the bag turning machine 5 can be remotely controlled to tilt the silicon water bag 4 for silicon water pouring. During pouring, the filling condition of the casting ingot mold 9 on the ingot mold transfer trolley 8 is checked in real time through the monitoring camera 7 (one ingot mold transfer trolley is equipped with a casting ingot mold). After one casting ingot mold 9 is filled, the ingot mold transfer trolley 8 is remotely controlled to move forward to perform the pouring operation of the next casting ingot mold 9.

[0017] According to field work experience, one silicon water bag can be used to cast five ingot mold carts. Therefore, five ingot mold transfer carts can be designed as a group of casting units, wherein the first ingot mold transfer cart 8 is a remote-controlled electric-driven cart, and the remaining ingot mold transfer carts 8 are traction-type unpowered carts. When the monitoring camera 7 observes that the fifth ingot mold cart of the previous group of casting units has begun to be cast, the silicon water bag transfer cart 3 on another silicon water bag transfer track 2 must transfer the silicon water bag 4 filled with silicon water to the bag turning machine 5 at the end of the track to wait. After the previous silicon water bag is cast, the bag turning machine 5 at the end of the other silicon water bag transfer track 2 is remotely controlled to dump the bag, and the casting operation of the next group of ingot mold carts 8 is completed. This cycle is repeated to achieve continuous casting.

[0018] Among them, the capacity of one silicon water bag is sufficient to support the transfer cycle of the next silicon water bag, that is, after the previous silicon water bag is poured, the capacity of the next silicon water bag is sufficient to support the previous silicon water bag to return to the ore-arc furnace to re-receive silicon water and then come back. The silicon water bag transfer trolley 3 and the ingot mold transfer trolley 8 both adopt the steel ladle electric drive transfer trolley or similar structure in the prior art, such as the electric steel ladle transfer device disclosed in CN201620542077.6. The signal transmission between the silicon water bag transfer trolley 3, the bag turning machine 5, the ingot mold transfer trolley 8 and the monitoring camera 7 and the on-site PLC control cabinet 10 can adopt the 5G, Bluetooth, WIFI and other communication means in the prior art, and there is no limitation here.

[0019] The utility model can realize gapless continuous pouring through two silicon water bags. The transportation efficiency of the silicon water bags on the electric transfer trolley is 4 to 5 times that of the original hand-pushed trolley. It also reduces the number of personnel, and only 2 to 3 people are needed to complete the entire operation of silicon discharge, casting and transportation, which saves more time, improves production efficiency, reduces the influence of human factors, and makes the system more stable and efficient.

[0020] Finally, it should be noted that, except for the technical features described in the specification, the rest not described are the prior art known to the technical personnel in this profession.
