Description

Technical Field

[0001] The utility model relates to the field of crushers, and more specifically to a high-alumina brick waste crushing device. Background Art

[0002] High alumina bricks, also known as high alumina refractory bricks, are a type of refractory material mainly used in high-temperature industrial furnaces. They are called "high alumina" because their main component is alumina, and the content is usually high. In order to increase the utilization rate of high alumina bricks and reduce the waste of resources, it is generally necessary to crush the waste of high alumina bricks using crushing equipment to recycle the raw materials.

[0003] Although the existing crushing equipment has many advantages when used, its crushing mechanism is relatively simple, and the particles after being crushed by the crushing roller of the crusher are still relatively large. If you want to continue to obtain raw material particles with smaller particle size, you need to install a conveying equipment at the bottom of the crusher to convey the raw materials to the grinding equipment for secondary grinding. This not only increases the number of equipment installations and the floor space of the equipment, but also easily affects the grinding efficiency of the waste. Therefore, we proposed a high-alumina brick waste crushing equipment to solve the above problems. Utility Model Content

The top of the threaded shaft 11 passes through the corresponding position of the upper frame 3 and is threadedly connected to the inside of the corresponding internally threaded shaft seats 302.

[0026] The operating principle of this high alumina brick waste crushing equipment is:

[0027] First, start the crusher 1 and the secondary grinding mechanism 2, so that the motor on the crusher 1 drives the crushing roller inside the hopper to rotate, and the driving motor 7 drives the lower grinding disc 6 to rotate, and then the high-aluminum brick waste can be added through the hopper of the crusher 1, and crushed inside the crusher 1 (the specific principle and structure of the crusher here are already existing known technologies, so they will not be described in detail here), and the high-aluminum brick waste particles that have completed the primary crushing by the crusher 1 can directly fall into the opening 9 of the upper grinding disc 5 through the opening at the bottom of the hopper of the crusher 1, and then because the cross-sections of the upper grinding disc 5 and the lower grinding disc 6 are conical structures, the high-aluminum brick waste particles can fall into the grinding gap between the upper grinding disc 5 and the lower grinding disc 6, and are ground by the high-speed rotation of the lower grinding disc 6, and the ground high-aluminum brick waste particles can be thrown out through the outer edge of the bottom of the lower grinding disc 6, thereby completing the grinding work;

[0028] Since the upper frame 3 and the lower frame 4 are connected by a set of threaded shafts 11, and the bottom of the threaded shaft 11 is rotatably connected to the lower frame 4 through the shaft seat 402, and the top of the threaded shaft 11 is threadedly connected to the upper frame 3 through the internal threaded shaft seat 302, the lower frame 4 can be adjusted to rise and fall at the bottom of the upper frame 3 by rotating the threaded shaft 11 by adjusting the hand wheel, thereby achieving the effect of adjusting and controlling the grinding gap between the upper grinding disk 5 and the lower grinding disk 6, thereby achieving the effect of adjusting the grinding particle size.

[0029] Embodiment 2:

[0030] In view of the above embodiment 1, for further description, refer to Figure 3 The height of the lower grinding disc 6 is equal to that of the upper grinding disc 5 , and a spherical guide head is fixedly welded on the top of the lower grinding disc 6 , and a plurality of conical protrusions are fixedly connected to the grinding convex strip 8 at equal intervals.

[0031] By making the outer edge diameter of the bottom of the lower grinding disc 6 equal to the inner wall diameter of the bottom of the upper grinding disc 5 and the height of the lower grinding disc 6 equal to the height of the upper grinding disc 5, it is convenient to control the grinding gap between the upper grinding disc 5 and the lower grinding disc 6 when adjusting the lower grinding disc 6 to avoid interference during adjustment. The spherical material guide head fixedly welded on the top of the lower grinding disc 6 can play a certain material guiding role, making it convenient for high-aluminum brick waste to slide evenly into the grinding gap. The setting of the grinding convex strips 8 and the cone convex can increase the contact area of ​​the high-aluminum brick waste inside the grinding gap and improve the grinding effect.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
