Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick production, in particular to a refractory brick raw material crushing device. Background Art

[0002] Refractory bricks, also known as firebricks, are a type of refractory material with a specific shape and size. They are primarily used in smelting furnaces and can withstand temperatures of 1580°C to 1770°C. There are many types of refractory bricks, including silicon-alumina refractory bricks, alkaline refractory bricks, carbon-containing refractory bricks, zirconium-containing refractory bricks, and insulating refractory bricks, depending on their composition. Refractory brick crushing equipment is crucial to refractory brick production, as it affects the processing efficiency and quality of the raw materials.

[0003] In the actual production process, the existing device uses a roller crushing box to crush the raw materials, but there are raw materials with different particle sizes in the raw materials. For raw materials of different sizes (especially large pieces of raw materials), a single roller crushing has the problem of low crushing efficiency; and the grinding wheel has a low processing efficiency for the raw materials in the middle of the roller crushing box, and there is a crushing "dead zone", which is not conducive to the continuous crushing of the raw materials. Utility Model Content

[0004] In view of the above deficiencies in the existing technology, the purpose of the present invention is to provide a refractory brick raw material crushing device, which pre-screens the raw materials through the coordinated use of a discharge separation cylinder and an extrusion crushing box. Raw materials with smaller particle sizes fall by gravity onto the hemispherical buffer disperser in the roller compaction box and are dispersed into the roller compaction box for grinding. Raw materials with larger particles enter the extrusion crushing box for crushing and then enter the roller compaction box, thereby greatly improving the raw material crushing efficiency. Through the setting of the hemispherical protrusion, the raw materials are not easy to gather in the center, thereby greatly improving the continuous crushing effect of the raw materials.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The refractory brick raw material crushing device includes a discharge separation cylinder, a roller compaction box, and an extrusion crushing box. A separation screen is provided below the discharge separation cylinder. The separation screen is connected to the roller compaction box through a material collection guide. The discharge separation cylinder is connected to the extrusion crushing box, and the extrusion crushing box is connected to the roller compaction box. A hemispherical protrusion is provided below the roller compaction box.

[0007] The raw materials from the discharge separation cylinder flow into the roller crushing box and the extrusion crushing box by gravity.

[0008] The discharge and separation drum is tilted, with its lower end connected to the crushing box. A raised block is provided at the junction of the drum and the crushing box. This block acts as a buffer for the raw materials, preventing them from being discharged too quickly and causing excessive amounts of small particles to enter the crushing box.

[0009] The interior of the extrusion crushing box is provided with an extrusion crushing roller, and two extrusion crushing rollers are used in combination.

[0010] A grinding wheel driven by a stirring motor is provided inside the roller-type crushing box, and a supporting base is provided below the roller-type crushing box.

[0011] The hemispherical protrusion is located at the center of the support base, and the hemispherical protrusion does not contact the rolling wheel.

[0012] A material guide pipe is provided between the extrusion crushing box and the roller crushing box. A hemispherical buffer disperser is provided inside the roller crushing box. The hemispherical buffer disperser is located just below the aggregate guide.

[0013] The roller compaction box is provided with a buffer tank, and the buffer tank is connected with an induced draft fan.

[0014] The working principle of this utility model is:

[0015] After entering the discharge separation drum, the refractory brick raw materials slide along the separation screen by gravity. Small-sized raw materials, after passing through the separation screen, freely fall into the aggregate guide, then fall onto the hemispherical buffer disperser in the roller compaction box, where they are dispersed and crushed by the rollers. Larger particles enter the extrusion crushing box for crushing, and then enter the roller compaction box for further crushing. The buffer tank and induced draft fan begin operation. Raw materials from the discharge separation drum enter the roller compaction box and the extrusion crushing box by gravity.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By adopting the refractory brick raw material crushing device of the present invention, the raw materials are pre-screened through the coordinated use of the discharge separation cylinder and the extrusion crushing box. Raw materials with smaller particle sizes fall by gravity onto the hemispherical buffer disperser in the roller compaction box and are dispersed into the roller compaction box for grinding by the roller. Raw materials with larger particles enter the extrusion crushing box for crushing and then enter the roller compaction box, which greatly improves the raw material crushing efficiency. The setting of the hemispherical protrusion makes it difficult for the raw materials to gather in the center, which greatly improves the continuous crushing effect of the raw materials.
