Technical Field

[0001] This utility model relates to the field of furnace charge crushing technology, and in particular to a furnace charge crushing device for blast furnace combustion. Background Technology

[0002] A blast furnace uses steel plates as its outer shell, lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: the throat, the body, the waist, the belly, and the hearth. The furnace charge consists of broken small pieces of coke, with a particle size similar to sintered ore.

[0003] Small pieces of coke are crushed by a crushing device. The small pieces of coke crushed by the existing crushing device are discharged by an external trolley for collection. However, the trolley needs to be pushed into the machine body. Due to the limited space inside the machine body, the trolley cannot be accurately positioned after being pushed in.

[0004] In view of this, we propose a furnace charge crushing device for blast furnace combustion. Utility Model Content

The outer end of the inner rod of the telescopic rod body is fixedly connected to the bottom of the moving frame. The outer end of the sleeve of the telescopic rod body is fixedly connected to the top of the universal wheel. A spring is sleeved on the telescopic rod body.

[0014] Preferably, limiting blocks are fixed on both sides of the outer opening of the movable frame, and a baffle is connected between the two limiting blocks. The two ends of the baffle are respectively inserted into the slots opened on the inner side of the two limiting blocks.

[0015] Preferably, the groove on the inner side of the limiting block is closed at the bottom and open at the top.

[0016] Preferably, the top side of the outer end of the movable frame is provided with slots, which are engaged with the end of the baffle.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting up a support frame, a movable frame and a slide rail, has the advantage that the movable frame can be pulled out from the machine body and a trolley can be pushed in from the outside to restrict the material.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: A blast furnace charge crushing device, see [link to example]. Figures 1 to 5 It includes the crusher body 1, as well as the support frame 2 and the movable frame 3;

[0031] The support frame 2 is fixedly installed in the frame below the discharge end of the crusher body 1; the movable frame 3 is movably installed in the support frame 2; wherein, the two sides of the movable frame 3 are movably connected to the two inner side walls of the support frame 2 through the slide rails 4 respectively.

[0032] This utility model, by setting up a support frame 2, a movable frame 3 and a slide rail 4, has the advantage that the movable frame 3 can be pulled out from the machine body and a trolley can be pushed in from the outside to restrict the material. After being pushed in, the trolley can accurately receive the material. This solves the problem that the space inside the machine body is limited and the trolley cannot be accurately positioned after being pushed in.

[0033] Specifically, four movable structures 5 are arranged in a rectangular array on the bottom side of the movable frame 3; the movable structure 5 includes casters 501;

[0034] The caster wheel 501 is located below the bottom side of the movable frame 3. The top of the caster wheel 501 is connected to the bottom side of the movable frame 3 via the telescopic rod body 502. The outer end of the inner rod of the telescopic rod body 502 is fixedly connected to the bottom side of the movable frame 3. The outer end of the sleeve of the telescopic rod body 502 is fixedly connected to the top of the caster wheel 501. A spring 503 is sleeved on the telescopic rod body 502. The two ends of the spring 503 are fixedly connected to the bottom side of the movable frame 3 and the top of the caster wheel 501, respectively. The elastic coefficient of the spring 503 shall be selected and used by the technical personnel of this profession according to the actual situation.

[0035] This utility model, by setting up a universal wheel 501, a telescopic rod body 502 and a spring 503, has the advantages of assisting the movement of the support frame 2, and that when the moving frame 3 moves out of or into the support frame 2, the height of the universal wheel 501 is adaptively adjusted and changed without affecting the rolling of the universal wheel 501.

[0036] Furthermore, limiting blocks 301 are fixed on both sides of the outer opening of the movable frame 3, and a baffle 6 is connected between the two limiting blocks 301. The two ends of the baffle 6 are respectively inserted into the slots opened on the inner side of the two limiting blocks 301. The bottom end of the slot opened on the inner side of the limiting block 301 is closed and the top end is open.

[0037] This utility model, by setting a limiting block 301 and a baffle 6, has the advantage that after a trolley is placed in the moving frame 3, the trolley is blocked by the docking of the limiting block 301 and the baffle 6, so that the trolley is stable within the moving frame 3.

[0038] Furthermore, slots 302 are provided on both sides of the top outer end of the movable frame 3. The slots 302 are engaged with the end of the baffle 6. When the baffle 6 is removed, it can be positioned on the top side of the movable frame 3, making it less likely to be lost and easier to use.

[0039] Working principle: Using the device of this utility model, the movable frame 3 is pulled out from the support frame 2. When the universal wheel 501 changes from the bottom wall of the support frame 2 to contact the ground, under the action of the compressed spring 503, the telescopic rod body 502 extends, so that the universal wheel 501 rolls in contact with the ground until the movable frame 3 is completely pulled out of the machine body. The trolley is placed into the movable frame 3. The two ends of the baffle 6 are respectively inserted into the grooves opened on the inner side of the two limit blocks 301 to block the trolley. The movable frame 3 is pushed into the support frame 2. The universal wheel 501 changes from the ground to contact the bottom wall of the support frame 2. The spring 503 is compressed, and the telescopic rod body 502 shortens until the movable frame 3 is completely pushed into the support frame 2. Then the material is sent into the crusher body 1 for crushing. The crushed material falls into the trolley from the discharge end of the crusher body 1.

[0040] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
