Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical mechanical equipment, and in particular relates to a mud blasting machine used for a discharge port of a RKEF process electric furnace for laterite nickel ore. Background Art

[0002] Whether it is blast furnace smelting or electric furnace smelting, the mud gun machine is an indispensable equipment for plugging the furnace in front and behind. The function of the mud gun machine is to block the high-temperature melt discharge port, and the degree of blockage of the discharge port affects the hole-opening effect of the hole-opening machine when the melt is discharged next time. If the mud gun machine drives less mud into the discharge port and the depth is not enough, the slurry will solidify at the discharge port, causing the hole-opening machine to fail to drill smoothly and even damage the drill bit of the hole-opening machine. Therefore, the mud gun machine must be precisely controlled when driving the mud gun machine into the discharge port.

[0003] like Figure 1 As shown, the existing mud cannon machine usually adopts a connection method that is non-detachable or non-convenient to disassemble (such as flange, bolt assembly connection) between its mud cannon nozzle 100 and mud cylinder 200. Therefore, a mud adding port 300 needs to be set above the mud cylinder, and mud is added to the mud cylinder from the upper mud adding port. This mud adding method requires two people to cooperate with each other, one of whom controls the movement of the piston and the other adds mud, and the piston 400 needs to move back and forth many times to fill the mud cylinder. This method takes a long time to add mud, is cumbersome to operate, and has serious safety hazards. Once the two people do not cooperate well, it will cause serious personal safety. In addition, it is not conducive to the cleaning of residual mud residue.

[0004] At present, some smelters also use robots to add mud, but this method requires sufficient space to place the machine, and requires the specifications of the incoming materials to be consistent and neatly stacked. These conditions limit the use of robots. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a mud gun machine for the discharge port of the RKEF process electric furnace of laterite nickel ore, so as to reduce the mud adding time and improve the production efficiency. At the same time, it reduces the safety hazards in the mud adding process and improves the convenience of cleaning the residual mud.

[0006] The utility model solves the above problems through the following technical means:

[0007] A mud gun machine for the discharge port of an RKEF process electric furnace for laterite nickel ore comprises a mud gun nozzle, a mud cylinder and a piston which is sealingly and slidably assembled with the mud cylinder; mud gun nozzle pin seats are fixedly arranged on both sides of the mud gun nozzle, and mud cylinder pin seats are fixedly arranged on both sides of the mud cylinder, the mud gun nozzle pin seats and the mud cylinder pin seats on the same side are arranged correspondingly, and the two are hinged by a pin.

[0008] Furthermore, a stepped stop is provided at the joint between the mud cylinder and the mud gun nozzle, and the corresponding end of the mud gun nozzle is sealingly engaged with the stop.

[0009] Furthermore, the mud gun nozzle pin seat is inserted between the two mud cylinder pin seats on the corresponding side, and then the mud gun nozzle pin seat and the mud cylinder pin seat are hinged by inserting the pin.

[0010] Furthermore, the mud gun nozzle pin seat is fixed to the mud gun nozzle by welding or integrally connected and fixed.

[0011] Furthermore, the mud cylinder pin seat is fixed to the mud cylinder by welding or integrally connected thereto.

[0012] Furthermore, the piston is driven to reciprocate by an electric mechanism or a hydraulic mechanism.

[0014] 1. The utility model provides a mud gun machine for the discharge port of the RKEF process electric furnace of laterite nickel ore, wherein the mud gun nozzle can be conveniently opened in a hinged and flipped manner relative to the mud cylinder. After opening the mud gun nozzle, the mud cylinder can be filled with mud at one time, and there is no need to move the piston to add mud multiple times, which can effectively reduce the time for adding mud and improve working efficiency.

[0015] 2. When adding mud, two people are not required to cooperate. Just move the piston to the retraction point, and one person can complete the mud adding, avoiding personal injury caused by operating errors.

[0016] 3. Open the mud gun nozzle to remove the residual mud residue and other debris in the mud gun nozzle and mud tank to avoid contamination of the new mud material added again and to prevent mud residue from clogging the mud gun nozzle. BRIEF DESCRIPTION OF THE DRAWINGS
