Description

Technical Field

[0001] The utility model relates to the technical field of dredging devices, in particular to a dredging device for a quenching slag groove of a yellow phosphorus electric furnace. Background Art

[0002] Phosphorus slag is one of the by-products of yellow phosphorus. For every ton of yellow phosphorus produced in the industry, about ten tons of phosphorus slag is produced. Of course, its output is related to the raw materials, proportions and production process of yellow phosphorus production. Phosphorus slag is usually used as raw material for silicate cement, slag bricks, silicon waste, white carbon black, etc.

[0003] The quenching slag pool and slag water circulation pool in the yellow phosphorus workshop are connected by a quenching slag ditch, and then the quenching slag water in the slag water circulation pool is used for quenching, cooling and lowering the temperature of the slag in front of the furnace by a slag flushing pump in front of the furnace. The quenching slag water overflows the sewage in the quenching slag pool to the slag water circulation pool through the quenching slag ditch. There is often fine phosphorus slag accumulation in the quenching slag ditch. If it is not discovered or dredged in time, it will lead to insufficient quenching slag water in the slag water circulation pool. If the amount of quenching slag water is insufficient when the furnace is discharged, and the slag flow is too large, there may be a risk of blocking the slag flushing ditch or explosion. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the phosphorus slag deposited in the quenching slag groove is easy to cause the quenching slag groove to be blocked, which poses a safety hazard.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a yellow phosphorus electric furnace quenching slag groove clearing device, including a mounting shaft and connecting ear plates fixed at both ends of the mounting shaft, the outer peripheral surface of the mounting shaft is provided with rake teeth, the rake teeth are evenly distributed along the axial direction of the mounting shaft and distributed around the axis of the mounting shaft, a slide is provided on one side of the mounting shaft, the slide is connected to the mounting shaft through a hinged rod, and the two ends of the hinged rod are respectively hinged to the same end of the mounting shaft and the slide.

[0006] Preferably, a roller is rotatably connected to the mounting shaft, and the rake teeth are arranged on the roller.

[0007] Preferably, annular protrusions are provided at both ends of the installation shaft, and the roller is located between the two annular protrusions.

[0008] Preferably, the cross section of the slide is trapezoidal.

[0009] Preferably, the rake teeth are in a truncated cone shape, and the outer diameter of the fixed end is larger than the outer diameter of the movable end.

[0010] The utility model provides a slag quenching groove dredging device for a yellow phosphorus electric furnace. Rake teeth are arranged on an installation shaft, and the installation shaft is dragged to move in the slag quenching groove. The rake teeth break up the sediments, and the sediments are shoveled up through a slide. After the slag flushing pump discharges water, the sediments can be further flushed, thereby achieving effective cleaning of the slag quenching groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1 and Figure 2 The utility model provides a slag ditch dredging device for a yellow phosphorus electric furnace, comprising a mounting shaft 1 and connecting ear plates 2 fixed at both ends of the mounting shaft 1, the outer peripheral surface of the mounting shaft 1 is provided with rake teeth 4, the rake teeth 4 are evenly distributed along the axial direction of the mounting shaft 1 and distributed around the axis of the mounting shaft 1, a slide 6 is provided on one side of the mounting shaft 1, the slide 6 is connected to the mounting shaft 1 through a hinge rod 5, and the two ends of the hinge rod 5 are respectively hinged to the same ends of the mounting shaft 1 and the slide 6.

[0016] Both ends of the installation shaft 1 are provided with connecting ear plates 2, and a circular hole is provided in the middle of the connecting ear plates 2. After the cover plate on the quenching slag groove is removed by passing a steel wire through the circular hole, the installation shaft 1 is placed in the quenching slag groove, and the installation shaft 1 is pulled along the quenching slag groove by artificial traction of the steel wire rope. During the movement, the phosphorus slag deposits inside the quenching slag groove are broken up by the rake teeth 4 on the outer peripheral surface of the installation shaft 1. After breaking up, the slide 6 behind the installation shaft 1 moves with the installation shaft 1, and shovels up the phosphorus slag when passing through the phosphorus slag deposits, so as to clean up the phosphorus slag deposits. Moreover, when cleaning the phosphorus slag deposits inside the quenching slag groove, the quenching slag water discharged by the slag flushing pump can further flush the broken phosphorus slag when passing through the quenching slag groove.

[0017] like Figure 1 As shown, in order to reduce the friction between the installation shaft 1 and the bottom of the quenching slag groove, a roller 3 is rotatably connected to the installation shaft 1, and the rake teeth 4 are arranged on the roller 3. The roller 3 arranged in a rolling manner can provide rolling support during the movement of the installation shaft 1, and the phosphorus slag deposits are crushed or scattered by the dense rake teeth 4.

[0018] like Figure 1 and Figure 2 As shown, in order to ensure the stability of the rotation of the drum 3, annular protrusions are arranged at both ends of the installation shaft 1, and the drum 3 is located between the two annular protrusions.

[0019] like Figure 1 and Figure 2As shown, in order to realize the shoveling of the phosphorus slag deposits at the bottom of the quenching slag groove by the slide 6, the cross section of the slide 6 is trapezoidal.

[0020] like Figure 1 and Figure 2 As shown, in order to increase the force of the rake teeth on the phosphorus slag deposits, the rake teeth 4 are truncated cone-shaped, and the outer diameter of the fixed end is larger than the outer diameter of the movable end. In addition, the movable end of the rake teeth 4 can also be set to a hemispherical structure to reduce wear.
