A crushing device and crushing method for producing refractory materials

Abstract

The invention relates to the field of crushing equipment, in particular to a crushing device and a crushing method for producing a fireproof material. The crushing device comprises a crushing and stirring mechanism, a material grinding mechanism and a feeding box which is obliquely arranged, wherein the crushing and stirring mechanism and the material grinding mechanism are both communicated withthe feeding box; the material grinding mechanism comprises a material grinding cabinet, a material grinding assembly and an arc-shaped plate, wherein a discharging funnel is arranged at the bottom ofthe material grinding cabinet; four supporting frames are arranged below the arc-shaped plate; a buffer spring is arranged between the top of each supporting frame and the bottom of the arc-shaped plate; a discharging opening is formed in the center of the bottom of the arc-shaped plate; and a sealing assembly is arranged below the arc-shaped plate. The crushing device has the beneficial effects that the raw materials of the fireproof material can be subjected to secondary crushing operation through the crushing mechanism and the material grinding mechanism, so that the situation that the rawmaterials are incomplete is avoided, and dust in the crushing cabinet can be subjected to dust reduction operation through a spray dust reduction assembly, and therefore, potential safety hazards caused by too much dust to the health of workers are avoided.

technical field [0001] The invention relates to the field of crushing equipment, in particular to a crushing device and a crushing method for producing refractory materials. Background technique [0002] Refractory materials are a kind of inorganic non-metallic materials with a refractoriness not lower than 1580 degrees Celsius. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. Most refractory materials are made of natural Ores are processed, and crushing devices are needed at this time. Traditional crushing devices will generate a lot of dust during work, which will bring respiratory diseases and other occupational diseases to workers, and bring greater safety hazards to workers; The traditional crushing device crushes the raw materials at one time, and the raw materials will not be crushed completely if the crushing operation is performed only once, which brings troubles to the follow-up ...

Problems solved by technology

[0002] Refractory materials are a kind of inorganic non-metallic materials with a refractoriness not lower than 1580 degrees Celsius. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. Most refractory materials are made of natural Ores are processed, and crushing devices are needed at this time. Traditional crushing devices will generate a lot of dust during work, which will bring respiratory diseases and other occupational diseases to workers, and bring greater safety hazards to workers; The traditional crushing device crushes the raw materials at one time, and the raw materials will not be crushed completely if only one crushing operation is performed, which brings troubles to the follow-up work of the workers.

CN203842662U is a crushing device for refractory raw materials, which takes into account the dust-proof problem in the crushing work, but has a good dust-absorbing effect on the dust near the pipe through the dust-absorbing pipeline, and has a good dust-absorbing effect on the dust caused by the collision of raw materials. The dust in a higher space cannot be effectively sucked away;

[0003] The crushing device for refractory materials disclosed in CN106944195A also adopts the design of exhaust fan and dust collection box to remove dust, and also has the disadvantage of limited adsorption range

The crushing device disclosed in CN105381857A takes into account fan dust suction and spray dust removal during dust removal. However, during the processing of refractory materials, changes in humidity will have a certain impact on the fire resistance and fire resistance of materials. Therefore, the existence of spray is inevitable. It will cause the material in processing to absorb a certain amount of water, which will affect the performance of the material and cause unnecessary damage
