The slag is a high-temperature solid substance, about 1000℃, and a small amount of molten silicon liquid remains on the surface. In order not to affect the smooth progress of the process, the slag in the silicon bag needs to be cleaned in time.

[0003] The traditional industrial silicon furnace slag cleaning device is a slag scraper, which is constructed as a forklift. A connecting rod is provided at the front end of the forklift, and a rectangular steel plate is provided at the head of the connecting rod. After the silicon liquid is poured into the silicon bag, the silicon bag is kept horizontally on the support frame. The personnel drive the forklift to insert the connecting rod and the steel plate into the silicon bag, scrape the slag with the steel plate, peel the slag off the side wall of the silicon bag, and the slag falls into the slag box.

[0031] The traditional industrial silicon furnace slag cleaning device is a slag scraper, which is constructed as a forklift with a connecting rod at the front end and a rectangular steel plate at the head of the connecting rod. After the silicon liquid is poured into the silicon bag, the silicon bag is kept horizontally on the support frame. The personnel drive the forklift to insert the connecting rod and the steel plate into the silicon bag, scrape the slag with the steel plate, peel the slag off the side wall of the silicon bag, and the slag falls into the slag box.

[0032] Since the slag is distributed on the side walls and bottom of the silicon bag, personnel need to constantly insert or remove the connecting rods and the attached steel plates into or out of the silicon bag, and constantly adjust the position to scrape the slag clean. The operation is time-consuming, labor-intensive, and has low work efficiency. Moreover, when the operation time is long, the slag is completely solidified on the inner lining of the bag wall, making cleaning more difficult.

[0033] The main purpose of the utility model is to provide a slag cleaning device, aiming to solve the problem of how to reduce the labor intensity of cleaning slag and improve work efficiency.

[0035] In an embodiment of the utility model, the first drive component 21 is movably installed on the frame 1. When the slag in the silicon bag 200 needs to be cleaned, the first drive component 21 moves relative to the frame 1 in a direction close to the silicon bag 200 so as to send the spiral reamer 3 into the silicon bag 200. At the same time, the first drive component 21 drives the spiral reamer 3 to rotate relative to the silicon bag 200 through the rotating shaft 22, so that the spiral reamer 3 can break the slag in the silicon bag 200, and the broken slag can also move along the texture of the spiral reamer 3 until it is discharged from the silicon bag 200. After the slag is cleaned, the first drive component 21 moves relative to the frame 1 in a direction away from the silicon bag 200 so as to move the spiral reamer 3 out of the silicon bag 200 to complete the cleaning process.

Compared with the structure of using a slag removal vehicle, the slag located on the side wall and the bottom of the silicon bag 200 can be cleaned by the spiral reamer 3, and the broken slag can also move along the texture of the spiral reamer 3 until it is discharged from the silicon bag 200. There is no need for the staff to continuously operate the machine to adjust the position to clean the slag, which effectively reduces the labor intensity of the staff in cleaning the slag.

[0038] According to an embodiment of the utility model, the first drive assembly 21 includes a first drive member 211 and a mounting frame 212 which are connected to each other, the output end of the first drive member 211 is connected to the rotating shaft 22, and the mounting frame 212 is slidably matched with the frame 1; specifically, by setting the mounting frame 212 to slide with the frame 1, the first drive member 211 can move relative to the frame 1 with the mounting frame 212, thereby facilitating the spiral reamer 3 to clean the slag in the silicon bag 200.

[0039] In one embodiment, the mounting frame 212 includes a mounting plate 2121 and a roller 2122 that are connected to each other. The mounting plate 2121 is connected to the first driving member 211. A track (not shown) is provided on the frame 1. The track extends in a horizontal direction, and the roller 2122 cooperates with the track in a rolling manner. Specifically, the horizontal direction is the left-right direction, and the track extends in the left-right direction. Through the rolling cooperation between the roller 2122 and the track, the first driving member 211 can move along the track with the mounting plate 2121, thereby preventing the first driving assembly 21 and the spiral reamer 3 from shifting during the movement, so that the spiral reamer 3 can accurately extend into the silicon bag 200 to clean the slag, effectively improving the stability and reliability of the operation of the slag cleaning device 100.

In this embodiment, the second drive assembly can be transmission-connected to the mounting plate 2121 using a motor or a reducer, and the specific form of the second drive assembly is not limited in this embodiment.

[0042] In one embodiment, the slag cleaning device 100 also includes a controller (not shown in the figure), and the first drive component 21 is electrically connected to the controller; and / or, the second drive component is electrically connected to the controller; specifically, in order to improve the working environment of the staff and prevent the staff from being scalded by high-temperature substances and causing safety accidents, in the present embodiment, the first drive component 21 and the second drive component are both electrically connected to the controller, and the first drive component 21 and the second drive component can be remotely controlled by setting the controller.

It also avoids the situation where the slag adheres to the lining of the silicon bag 200 due to long-term slag cleaning.

[0043] According to an embodiment of the utility model, the slag cleaning device 100 also includes a controller, and the first drive component 21 is electrically connected to the controller; by setting the controller, remote control of the first drive component 21 can be achieved, and the controller can be set away from the silicon bag 200, so that the staff can avoid contact with the high temperature environment, ensuring the safety of the staff's work, and the first drive component 21 and the spiral reamer 3 can be started or stopped through the controller. The operation is convenient and efficient, which greatly saves time and labor costs, and can also avoid the situation where the slag sticks to the lining of the silicon bag 200 due to long-term slag cleaning.

[0044] According to another embodiment of the utility model, the slag cleaning device 100 also includes a controller, and the second drive assembly is electrically connected to the controller; by setting the controller, remote control of the second drive assembly can be achieved, and the controller can be set away from the silicon package 200, so that the staff can avoid contact with the high temperature environment, ensuring the safety of the staff's work, and the second drive assembly can be moved or stopped relative to the frame through the controller, which is convenient and efficient to operate, greatly saving time and labor costs.

[0045] In one embodiment, the first drive component 21 also includes a support frame 213, and the rotating shaft 22 is rotatably installed on the support frame 213, the support frame 213 is connected to the mounting frame 212, and the support frame 213 is used to support the rotating shaft 22; specifically, in order to improve the operating stability of the slag cleaning device 100, the first drive component 21 also includes a support frame 213, and the rotating shaft 22 is rotatably installed on the support frame 213, and the support frame 213 is used to support the rotating shaft 22, thereby preventing the rotating shaft 22 from shifting in the vertical direction, and effectively ensuring the operating stability of the slag cleaning device 100.

[0046] In one embodiment, the diameter of the spiral reamer 3 is 90% to 100% of the inner diameter of the silicon bag 200. Specifically, when a slag scraper is used to clean the slag, the staff needs to observe and judge the adhesion state of the high-temperature slag on the side wall and the bottom of the silicon bag 200. On the one hand, it is difficult for the staff to observe, and on the other hand, there is a risk of decreased vision for the staff to observe the high-temperature luminous red molten material for a long time. In this embodiment, the diameter of the spiral reamer 3 is 90% to 100% of the inner diameter of the silicon bag 200. When the spiral reamer 3 is inserted into the inner wall of the silicon bag 200 and rotates, the slag in various places in the silicon bag 200 can be accurately cleaned, without Manual observation and judgment of the adhesion state of the slag are required, which effectively reduces the manpower and workload and has a higher cleanliness. The slag cleaned out by the slag scraper is irregular, large-sized, and blocky. The particle size of some slag is more than 30 cm. If the slag is to be reused, additional crushing is required, which either requires a large amount of manpower to crush, which is time-consuming and labor-intensive, or requires a jaw crusher to crush, which increases the cost and is very inconvenient. However, by using the slag cleaning device 100, the particle size of the crushed slag is less than 5 cm, and the slag can be directly reused without additional crushing. It is efficient and convenient, and can meet user needs without additional crushing.

[0047] In one embodiment, the length of the spiral reamer 3 is not less than the depth of the silicon bag 200; specifically, the length of the spiral reamer 3 is greater than or equal to the depth of the silicon bag 200, so that the broken slag can move along the lines of the spiral reamer 3 until it is discharged from the silicon bag 200, and there is no need for manual assistance to transport the cleaned slag out of the silicon bag 200, which is more efficient and convenient.

[0048] In one embodiment, the spiral reamer 3 includes a heat-resistant spiral reamer; specifically, since the slag is a high-temperature solid substance, about 1000°C, and a small amount of molten silicon liquid remains on the surface, in order not to affect the subsequent process, a heat-resistant spiral reamer can be used to break the slag in a hot state, avoiding the traditional method of obtaining cold slag. The cold crushing of slag requires a lot of manpower or the use of additional machinery. The use of the slag cleaning device 100 effectively improves production efficiency and reduces the cost of use. The use of a heat-resistant spiral reamer can continue to work under high temperature conditions, thereby improving the strength and service life of the spiral reamer 3.

[0049] In one embodiment, the slag cleaning device 100 also includes a slag box 5, which is disposed below the outlet of the silicon bag 200, and is used to contain slag; specifically, the slag box 5 is disposed below the outlet of the silicon bag 200, and when the broken slag moves along the texture of the spiral reamer 3 until it reaches the outlet of the silicon bag 200, the slag automatically falls into the slag box 5, and there is no need to manually collect the slag, which is efficient and convenient, and effectively reduces the workload of the staff.
