Description

Technical Field

[0001] The utility model belongs to the technical field of industrial silicon smelting, and particularly relates to a wooden stick lengthening device for industrial silicon furnace discharge. Background Art

[0002] Industrial silicon, also known as metallurgical-grade silicon, is industrially purified elemental silicon. Due to different raw material structures, it is mostly divided into two categories: chemical-grade metallic silicon and metallurgical-grade metallic silicon. It is mainly used as the main raw material for the production of organic silicon, polysilicon, and single-crystal silicon, the preparation of high-purity semiconductor materials, and the formulation of alloys (aluminum alloys) for special purposes. The main controlled trace elements are Fe, Al, and Ca, and different production grades are defined by their different contents.

[0003] During the industrial silicon smelting process, in order to reduce the impact of iron materials and tools entering the silica stone on the quality of the alloy, wooden sticks are used to clear the furnace eye when discharging silicon in front of the furnace, ensuring that the furnace eye is unobstructed and silicon can be discharged smoothly. During normal production, the wooden sticks used are 30-80mm in diameter and about 6 meters in length. When discharging silicon, the operator holds the thick end of the wooden stick and stands on a platform more than 2 meters away from the furnace eye to poke the furnace eye. This operation method has the following problems: First, the wooden stick's poking effect is poor, and the goal of deep poking of the furnace eye cannot be achieved, resulting in a large amount of wooden stick waste. The normal furnace eye depth is 800-1000mm. If the operator stands 2 meters away from the furnace eye, there is about 2.8-3 meters of wooden stick that cannot be used, resulting in a large waste of wooden sticks when poking the furnace eye. At the same time, the wooden sticks need to be frequently replaced for operation, affecting the poking time and efficiency. Second, the wooden stick is irregular, and the personnel directly hold the thick end to poke the hole, which affects the poking force of the personnel and makes the poking force uneven, and also poses a safety risk; third, in order to improve the poking effect, the personnel poke the hole close to the furnace eye. The temperature is high during the process of taking the hole out of the furnace, and there is a risk of silicone water splashing and scalding when poking the hole. Utility Model Content

[0004] The utility model aims to provide a wooden stick lengthening device for industrial silicon furnace discharge, so as to solve the problems of insufficient wooden stick length, poor poking effect and large waste of wooden sticks when directly using wooden sticks to poke the furnace eyes during the process of industrial silicon furnace discharge.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device for extending wooden sticks for unloading an industrial silicon furnace comprises a handle and a sleeve arranged at one end of the handle. The side wall of the sleeve is connected to the side wall of the handle. The central axes of the sleeve and the handle are parallel. A screw hole is provided on the side wall of the sleeve. A fastening screw is screwed into the screw hole and is perpendicular to the central axis of the sleeve.

[0007] In order to further realize the present invention, the length of the connection between the sleeve and the handle is 200 mm.

[0008] In order to further realize the present invention, the length of the sleeve is 500 mm and the diameter is 80 mm.

[0009] In order to further realize the present invention, the length of the handle is 2000 mm and the diameter is 30 mm.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The function of the sleeve with the fastening screw designed in the utility model is to tighten the wooden stick placed inside the sleeve to prevent it from loosening during the process of the wooden stick poking the furnace eye. During the process of industrial silicon being taken out of the furnace, the thick end of the wooden stick with a diameter of 30-80 mm and a length of 6 meters used for poking the furnace eye is deeply inserted into the sleeve, and the fastening screw is used to tighten the wooden stick. When poking the furnace eye, the staff can hold the handle and poke the wooden stick back and forth deep into the furnace eye.

[0012] The utility model solves the problems of insufficient length of wooden sticks, poor poking effect, and large waste of wooden sticks when directly using wooden sticks to poke the furnace eye during the process of industrial silicon being taken out of the furnace, improves the poking efficiency and utilization rate of wooden sticks in front of the furnace, and reduces the risk of scalding caused by being too close to the furnace eye during the poking operation. It has been promoted and applied in all industrial silicon furnaces.

[0013] The utility model is fast, practical, economical and has high safety performance, and creates conditions for the safety of the silicon discharge process in front of the industrial silicon furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of the utility model;

[0015] The meanings of the accompanying figures are as follows: 1. handle; 2. sleeve; 3. screw hole; 4. fastening screw. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, a wooden stick extension device for unloading an industrial silicon furnace comprises a handle 1 and a sleeve 2 arranged at one end of the handle 1. The side wall of the sleeve 2 is connected to the side wall of the handle 1. The central axes of the sleeve 2 and the handle 1 are parallel. A screw hole 3 is provided on the side wall of the sleeve 2. A fastening screw 4 is screwed into the screw hole 3 and is perpendicular to the central axis of the sleeve 2. The length of the connection between the sleeve 2 and the handle 1 is 200 mm. The length of the sleeve 2 is 500 mm and the diameter is 80 mm. The length of the handle 1 is 2000 mm and the diameter is 30 mm.

[0018] A handle 1 is made of a seamless steel pipe with a diameter of 30mm and a length of 2000mm. It is welded to a sleeve 2 with a diameter of 80mm and a length of 500mm. The joint between the sleeve 2 and the handle 1, i.e., the weld overlap, is 200mm long. A screw hole 3 and a fastening screw 4 are set in the middle of the sleeve 2. A fastening device is made using bolts. Its function is to tighten the wooden stick placed inside the sleeve 2 to prevent it from loosening during the process of poking the furnace eye with the wooden stick. During the process of industrial silicon being taken out of the furnace, the thick end of a wooden stick with a diameter of 30-80mm and a length of 6 meters is inserted into the sleeve 2, and the fastening screw 4 is passed into the screw hole 3 to tighten the wooden stick. When poking the furnace eye, the operator holds the handle 1, stands at a distance of more than 3 meters from the furnace eye, and pokes the wooden stick back and forth deep into the furnace eye. The extension device is simple to operate, and it is convenient, quick and efficient to extend wooden sticks, effectively improving the effect of poking the furnace eye and the efficiency of using wooden sticks, and reducing the amount of wooden sticks used by 1 / 3; during operation, personnel hold the flat sleeve handle, which is convenient for operation and force; at the same time, due to the addition of a 2-meter sleeve handle, personnel do not need to work close to the furnace eye, reducing the safety risk of burns to personnel.
