Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for yellow phosphorus electric furnaces, in particular to a furnace blocking tool for controlling the slag flow rate of an electric furnace eye. Background Art

[0002] In the field of yellow phosphorus, electric furnace method is mostly used to produce phosphorus. The processed phosphate ore, white coal and silica are continuously added into the electric furnace in a certain ratio. Electric energy is converted into heat energy to melt them to produce a chemical reduction reaction, generating a mixture of yellow phosphorus and coal gas. At the same time, the high-temperature slag and ferrophosphorus are regularly discharged from the slag mouth and iron mouth of the electric furnace.

[0003] During the operation of the yellow phosphorus electric furnace, the furnace eye is a part that is easily worn out. After the newly replaced furnace eye has been used for a period of time, the furnace eye corrodes and becomes larger, resulting in an increase in the slag flow rate during the furnace discharge process, which is difficult to control and poses a greater safety risk. The usual practice is to insert wood or solid steel pipes into the furnace eye to control the flow of the electric furnace slag. However, the electric furnace is discharged about 10 times a day, and the slag flow time each time is about 40 minutes. Using wood to control the flow of the electric furnace slag consumes a lot of wood and is costly. Using solid steel pipes is bulky, inconvenient to operate, and more costly, which is uneconomical and unsafe. Summary of the invention

[0004] The technical problem to be solved by the utility model is that currently, wood sticks are used to seal furnace eyes, which results in large wood consumption and high cost, while steel pipes are used to seal furnace eyes, which results in poor safety and economy.

[0006] Preferably, a guide rod is fixedly provided on the outer side wall of the movable splint, and the guide rod passes through the connecting tube.

[0007] Preferably, the ends of the carbon rods are continuously provided with adapting grooves, and the opposite side walls of the fixed clamping plate and the movable clamping plate are both provided with engaging protrusions adapted to the adapting grooves.

[0008] Preferably, a positioning step is provided at one end of the carbon rod close to the adapting groove, and when the fixing clamp plate abuts against the side wall of the positioning step, the engaging protrusion faces the adapting groove.

[0009] Preferably, a cavity is provided at the connecting end of the connecting tube and the handle, and the cavity is filled with sealing filler.

[0010] Preferably, a cavity is provided at one end of the handle close to the connecting tube, and the cavity is filled with heat-insulating filler.

[0011] Preferably, an anti-scalding rope is fixedly wound around the outer wall of the end of the handle away from the connecting tube.

[0012] 1. The utility model provides a furnace blocking tool for controlling the slag flow rate of an electric furnace eye. The carbon rod and the handle are connected by a connecting tube.

[0020] like Figure 1-4 As shown, in order to extend the service life of the furnace blocking tool and enhance convenience. The utility model provides a furnace blocking tool for controlling the slag flow rate of an electric furnace, comprising a connecting tube 1, a carbon rod 8 buckled inside one end of the connecting tube 1, and a handle 2 fixedly connected to the other end of the connecting tube 1, an arc-shaped fixed clamping plate 3 is fixedly arranged on one side of the inner side of the connecting end of the connecting tube 1 and the carbon rod 8, and an arc-shaped movable clamping plate 4 is slidably arranged on the other side relative to the fixed clamping plate 3, the inner diameters of the fixed clamping plate 3 and the movable clamping plate 4 are equal to the outer diameter of the carbon rod 8, and a locking screw 7 for pressing the movable clamping plate 4 onto the carbon rod 8 is threadedly connected to the connecting tube 1.

[0021] The connecting tube 1 is made of a large-diameter steel pipe, and a radial plate is welded on one side of the inner wall of the connecting tube 1. A fixed splint 3 is welded through the radial plate. The fixed splint 3 and the movable splint 4 are cut from the same steel pipe, and the steel pipe is selected to be compatible with the carbon rod 8; one end of the carbon rod 8 is inserted into the connecting tube 1, and the locking screw 7 is rotated. The end of the locking screw 7 located in the connecting tube 1 pushes the movable splint 4 to move along the guide rod 5, and the carbon rod 8 is stably clamped by the movable splint 4 and the fixed splint 3.

[0022] A connecting threaded barrel 6 is fixedly provided on the outer wall of the connecting barrel 1 , and the connecting threaded barrel 6 is threadedly connected to the locking screw 7 .

[0023] The other end of the connecting tube 1 is sealed with a steel plate, and after sealing, a steel pipe smaller than the connecting tube 1 is connected to form a handle 2. The staff holds the handle 2 and uses a carbon rod 8 to seal the furnace eye of the yellow phosphorus electric furnace.

[0024] like Figure 1 and Figure 3 As shown, in order to ensure the stability of the movement of the movable clamping plate 4, the movable clamping plate 4 can stably clamp the carbon rod 8. A guide rod 5 is fixedly arranged on the outer side wall of the movable clamping plate 4, and the guide rod 5 passes through the connecting tube 1.

[0025] like Figure 1 and Figure 4 The ends of the carbon rods 8 are continuously provided with adapting grooves 9 , and the opposite side walls of the fixed clamping plate 3 and the movable clamping plate 4 are both provided with engaging protrusions adapted to the adapting grooves 9 .

[0026] When clamping the carbon rod 8, the adapter groove 9 is preferably set to a position corresponding to the bite protrusion. In the process of the movable splint 4 pushing the carbon rod 8 to move, the bite protrusions on the opposite side walls of the fixed splint 3 and the movable splint 4 enter the adapter groove 9, bite the carbon rod 8, achieve stable clamping, and avoid sliding during use.

[0027] like Figure 4 As shown, in order to facilitate the positioning of the bite protrusion and the adapting groove by the staff, a positioning step 11 is provided at one end of the carbon rod 8 close to the adapting groove 9, and when the fixing clamp plate 3 abuts against the side wall of the positioning step 11, the bite protrusion faces the adapting groove 9.

[0028] Unscrew the locking screw 7 and use the guide rod 5 to pull the movable splint 4 outward to increase the gap between the fixed splint 3 and the movable splint 4, so that the positioning step 11 can pass through the gap between the fixed splint 3 and the movable splint 4, and the fixed splint 3 abuts against the end wall of the positioning step 11. At this time, the positioning of the engaging protrusion and the adapter groove 9 is achieved, thereby improving the efficiency of positioning.

[0029] like Figure 4 The connection end of the connection tube 1 and the handle 2 is provided with a cavity, and the cavity is filled with a sealing filler 12. The sealing filler 12 is made of electrode paste to ensure the sealing of the connection tube 1.

[0030] like Figure 4 As shown. The handle 2 is provided with a cavity at one end close to the connecting tube 1, and the cavity is filled with a heat insulating filler 13. Using loess as the heat insulating filler 13 not only saves costs, ensures heat insulating performance, but also has a relatively light weight.

[0031] like Figure 1 As shown. The outer wall of the end of the handle 2 away from the connecting tube 1 is fixedly wound with an anti-scalding rope 10. The anti-scalding rope 10 is wound around the handle 2 to form an anti-scalding gripping portion.
