[0016] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0017] like Figures 1 to 4As shown, a refractory material crushing device described in the utility model comprises a shell 1, the top of the shell 1 is open, which is convenient for feeding, and the bottom of the shell 1 is provided with supporting legs, and the bottom of the shell 1 between the supporting legs is connected to a diversion bin 2, so that the crushed materials can be discharged in time; a crushing roller 3 is arranged in the shell 1, and the crushing roller 3 is driven by a motor 4. Specifically, the motor 4 can use the transmission between the pulley and the belt to realize the rotation of the crushing roller 3, and a protective cover is arranged outside the pulley to ensure the safety during operation. Since this transmission method is the existing technology commonly used in this field, the specific setting of the pulley will not be described in detail; wherein the crushing roller 3 is a hollow structure inside, and a crushing toothed disc 5 is arranged outside it at intervals, A dust suction hole 6 which is connected to the inside of the crushing roller 3 is provided on the crushing roller 3 between adjacent crushing tooth discs 5; a dust collecting box 7 which is connected to the inside of the crushing roller 3 is provided on one side of the shell 1, and a dust suction fan 8 is provided on the dust collecting box 7; a filter cover is provided between the dust suction fan 8 and the dust collecting box 7; it can ensure that dust enters the dust collecting box 7; a door panel 9 is hinged on one side of the dust collecting box 7, which is convenient for timely cleaning of the dust collected inside; when working, by turning on the dust suction fan 8, the dust generated in the crushing process will be sucked into the cavity in the middle of the crushing roller 3 through the dust suction hole 6, and enter the dust collecting box 7 from the cavity in the middle of the crushing roller 3 for temporary storage; the amount of dust escaping into the surrounding environment during the crushing process can be greatly reduced, while reducing the harm to the staff.

[0018] Furthermore, in the present embodiment, a filter screen 10 is provided in the dust suction hole 6, and the filter screen 10 is used to intercept granular debris to prevent the granular debris from entering the cavity in the crushing roller 3; preferably, the filter screen 10 is a hemispherical structure recessed toward the inside of the crushing roller 3, so as to ensure the dust suction efficiency while preventing the filter screen 10 from protruding or being flush with the surface of the crushing roller 3, which may cause the filter screen 10 to deform or break due to contact and compression with the block raw materials during the crushing process, thereby ensuring the service life of the filter screen 10; in addition, in the present embodiment, the dust suction holes 6 in two adjacent columns are preferably arranged in a staggered state, which can ensure the dust suction effect while staggering the opening positions of the dust suction holes 6 to ensure the strength of the crushing roller 3.

[0019] In addition, a reinforcing edge 11 is protrudingly provided on the crushing roller 3 between two adjacent crushing tooth discs 5. The reinforcing edge 11 is preferably integrally formed with the crushing roller 3, and the dust suction hole 6 is located between adjacent reinforcing edges 11; the setting of the reinforcing edge 11 can not only enhance the structural strength of the crushing roller 3, but also intercept the particulate raw material and reduce the probability of the particulate material entering the dust suction hole 6; the spacing between the two reinforcing edges 11 can be set at a certain angle, that is, the spacing close to the crushing roller 3 is large, and the spacing away from the crushing roller 3 is small, so as to achieve strict entry and wide exit of dust and reduce the probability of particulate raw material entering.

[0020] Furthermore, a plurality of cleaning plates 12 are arranged on the inner wall of the shell 1, and the cleaning plates 12 are arranged at one end of the two crushing rollers away from each other, and the end of each cleaning plate 12 is correspondingly located between two adjacent crushing tooth disks 5; the cleaning plates 12 are arranged in an inclined state, and are located at the upper part of the crushing roller close to one end of the side wall of the shell 1. With the relative rotation of the two crushing rollers, the cleaning plates 12 can promptly remove the granular materials stuck between the two crushing tooth disks 5 to avoid affecting the dust collection work; in addition, cleaning teeth are preferably also provided at the bottom of the cleaning plate 12, and the cleaning teeth are located between two adjacent reinforcing edges 11. With the rotation of the crushing roller, the small granular materials stuck between the adjacent reinforcing edges 11 can be promptly removed, providing convenience for the normal dust collection work.

[0021] When the utility model is in use, with the addition of block materials, the motor 4 is started to drive the crushing roller 3 to rotate, so as to realize the extrusion and crushing operation of the material. At the same time, the dust suction fan 8 is turned on to timely suck the dust generated in the crushing process into the dust collecting box 7, and finally the inside of the dust collecting box 7 is cleaned. The utility model has a simple structure and is easy to use. It greatly reduces the amount of dust escaping into the surrounding environment when the material is crushed, improves the working environment, and reduces the adverse effects on the staff. It is highly practical.
