Description

Technical Field

[0001] The utility model belongs to the field of furnace eye blocking devices, in particular to a novel furnace eye blocking device. Background Art

[0002] Submerged arc furnace is also called electric arc furnace or electric resistance furnace. It is mainly used for reducing and smelting raw materials such as ore, carbonaceous reducing agent and solvent, and mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide.

[0003] Although the existing furnace eye plugging device can achieve the effect of quickly plugging the furnace eye under the control of a hydraulic cylinder or a motor, the diameter and height of the plugging rod are mostly fixed and difficult to adjust. The operation is relatively cumbersome when plugging furnace eyes of different apertures and heights. In addition, under the control of a hydraulic cylinder or a motor, it is easy to cause a certain impact on the furnace eye, which can easily cause the furnace eye to crack and be damaged, affecting the plugging effect. Utility Model Content

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the new furnace eye blocking device proposed in the utility model includes a base, and also includes an adjusting support mechanism and a blocking mechanism. The adjusting support mechanism is fixedly arranged on the upper part of the base. The adjusting support mechanism includes a lifting hydraulic cylinder. The lower end of the lifting hydraulic cylinder is fixedly connected to the upper part of the base. The upper end of the lifting hydraulic cylinder is fixedly provided with a mounting frame. The upper part of the mounting frame is fixedly provided with a fixed bracket. The blocking mechanism is arranged on the upper part of the fixed bracket. The blocking mechanism includes a control hydraulic cylinder. The fixed end of the control hydraulic cylinder is fixedly connected to the upper part of the fixed bracket. The movable end port of the control hydraulic cylinder is fixedly provided with a connecting rod. The front end of the connecting rod is provided with a spring and a damping. The outer ends of the spring and the damping are connected with a blocking rod. The blocking rod is set to a conical structure.

[0006] Furthermore, an auxiliary bracket is fixedly provided at the front end of the upper portion of the mounting frame, and the movable end of the control hydraulic cylinder is slidably connected to the upper portion of the auxiliary bracket.

[0007] Furthermore, a heat insulation layer is provided at the outer end of the blocking rod.

[0008] Furthermore, a counterweight block is provided at the rear of the base, and the counterweight block is movably connected to the upper part of the base.

[0009] Furthermore, a universal wheel is rotatably connected to the lower part of the base.

[0010] The beneficial effects achieved by the utility model using the above structure are as follows:

[0011] 1. The new furnace eye plugging device proposed in this scheme is characterized by arranging an adjustable support mechanism at the bottom of the plugging mechanism, controlling the height of the plugging mechanism by lifting the hydraulic cylinder, and setting the heat insulation layer to a conical structure. Under the control of the hydraulic cylinder, furnace eyes of different apertures and heights can be plugged, and the practicability is high.

[0012] 2. The new furnace eye blocking device proposed in this scheme can reduce the impact between the blocking rod and the furnace eye and avoid damage to the furnace eye during blocking by setting a spring and a damper between the connecting rod and the blocking rod.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1 and Figure 2As shown, a new type of furnace eye blocking device proposed in the utility model includes a base 1, and also includes an adjusting support mechanism 2 and a blocking mechanism 3. The adjusting support mechanism 2 is fixedly arranged on the upper part of the base 1, and the adjusting support mechanism 2 includes a lifting hydraulic cylinder 201, and the lower end of the lifting hydraulic cylinder 201 is fixedly connected to the upper part of the base 1, and the upper end of the lifting hydraulic cylinder 201 is fixedly provided with a mounting frame 202, and the upper part of the mounting frame 202 is fixedly provided with a fixed bracket 203, and the blocking mechanism 3 is arranged on the upper part of the fixed bracket 203, and the blocking mechanism 3 includes a control hydraulic cylinder 301, and the fixed end of the control hydraulic cylinder 301 is fixedly connected to the upper part of the fixed bracket 203, and the movable end port of the control hydraulic cylinder 301 is fixedly provided with a connecting rod 302, and the front end of the connecting rod 302 is provided with a spring 303 and a damping 304, and the outer ends of the spring 303 and the damping 304 are connected with a blocking rod 305, and the blocking rod 305 is set to a conical structure for blocking furnace eyes of various apertures.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, an auxiliary bracket 204 is fixedly provided at the front end of the upper part of the mounting frame 202, and the movable end of the control hydraulic cylinder 301 is slidably connected to the upper part of the auxiliary bracket 204 to assist in supporting the blocking mechanism 3. The outer end of the blocking rod 305 is provided with an insulating layer 306 to reduce the heat in the furnace from escaping from the furnace eye. A counterweight block 4 is provided at the rear part of the base 1, and the counterweight block 4 is movably connected to the upper part of the base 1 to adjust the center of gravity of the device to avoid tipping over due to the blocking mechanism 3 being positioned too forward. The lower part of the base 1 is rotatably connected with a universal wheel 5 to move the device.

[0021] During specific use, the device is pushed to the furnace eye that needs to be blocked by the universal wheel 5, and the lifting hydraulic cylinder 201 is started to control the height of the blocking mechanism 3 above the mounting frame 202, so as to facilitate the blocking of furnace eyes at different heights. The extension control hydraulic cylinder 301 is controlled to drive the connecting rod 302 and the blocking rod 305 to move forward. With the cooperation of the conical blocking rod 305, furnace eyes of different apertures can be blocked. At the same time, the spring 303 and the damping 304 at the connection between the blocking rod 305 and the connecting rod 302 can reduce the impact and shaking when the blocking rod 305 is connected to the furnace eye, and avoid the blocking rod 305 from having a large impact on the furnace eye under the control of the control hydraulic cylinder 301, thereby playing a certain protective role on the furnace eye.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
