Description
Technical Field
The utility model belongs to the field of cement production equipment, and particularly relates to a pollution-free crushing device for cement production.
Background
Cement is a powdered hydraulic inorganic cementitious material. Water is added and stirred to form slurry which can be hardened in air or water and can firmly bond sand, stone and other materials together.
The cement raw materials mainly comprise limestone raw materials, clay raw materials, iron ore, coal and the like, most raw materials are crushed in the cement production process, limestone is the raw material with the largest cement production amount, the particles before crushing are large, and the hardness of the limestone is high, so the limestone for producing the cement is required to be crushed.
However, the existing crushing equipment is provided with a feeding port and a discharging port, and the feeding port and the discharging port are not provided with dust collecting related devices, so that a large amount of dust generated by crushing can fly to the air from the feeding port and the discharging port, the environmental pollution around a production site is caused, and the health of production personnel is also harmed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a pollution-free crushing device for cement production, and aims to solve the technical problem that a large amount of dust flies into the air in the use process of crushing equipment in the prior art.
The pollution-free crushing device for cement production comprises a crushing mechanism, wherein the crushing mechanism comprises a crushing box body, a feeding port and a discharging port, the feeding port and the discharging port are arranged on the crushing box body, the crushing device further comprises a feeding channel, the feeding port is arranged on the side wall of the upper end of the crusher, the feeding channel is communicated with the feeding port, the discharging port is communicated with a discharging channel, the discharging channel is communicated with a dust collecting pipeline, and an exhaust fan is arranged in the dust collecting pipeline; one end of the dust collecting pipeline, which is far away from the discharge channel, is communicated with a water pool or a dust purification tank containing water, and the end of the dust collecting pipeline, which is far away from the discharge channel, is positioned below the liquid level.
The working principle of the scheme is as follows: the breaker of this scheme compares with conventional breaker, the lateral wall of the broken box that the dog-house set up, throw simultaneously a pay-off passageway of feed inlet department intercommunication, dust in kibbling in-process broken box mainly can be followed dog-house and discharge gate department and raised out, the pay-off passageway in this case then mainly is the distance that the dust that flies out in order to increase the feed inlet department spreads, let a large amount of dust subside in the pay-off passageway and reduce the dust that flies out through the discharge gate, so when implementing the present case, the length of pay-off passageway is enough long, can decide according to the size of broken box volume, the volume is the big more that raises dust greatly, then the pay-off passageway is longer, generally more than 3 meters.
The cement raw materials placed in the feeding channel can be pushed inwards by using the rake with a longer handle.
The discharge outlet is communicated with a discharge channel, the discharge channel is communicated with a dust collecting pipeline, an exhaust fan is installed in the dust collecting pipeline, and the exhaust fan is started to suck a large amount of air with dust at the discharge outlet into the dust collecting pipeline under the action of strong air flow. Because one end of the discharge channel of the dust collecting pipeline principle is communicated with a water pool or a dust purification tank containing water, and the end is positioned below the liquid level, air with dust enters the liquid level, a large amount of dust is settled in the water, and the purified air is discharged from the water and then discharged into the outside air.
The beneficial technical effect of this scheme is: this scheme is at the main raise dust position of broken box, dog-house and discharge gate department carry out subsiding of dust promptly, two kinds of modes have been adopted, firstly, set up the dispersion distance of longer conveying line extension dust, reduce the inertia of dust and subside, secondly, adopt the mode of convulsions air current with higher speed to concentrate the dust of collecting discharge gate department, and introduce the aquatic and subside, and then a large amount of and obvious reduction fly upward the dust volume in the external environment, and then show the environmental pollution degree that causes in the reduction production process and the injury degree to personnel.
Furthermore, the feeding channel is obliquely arranged towards the crushing box body. When the rake is used for pushing raw materials, the feeding channel can be slightly inclined towards the crushing box body in order to enable the cement raw materials to roll more easily under the inertia.
Further, pollution-free breaker is used in cement manufacture still includes transport mechanism, transport mechanism's discharge end is located the pay-off passageway, and transport mechanism's feed end is located outside the pay-off passageway. The conveying mechanism is used for replacing manual work to push the rake, so that labor can be saved, labor intensity is reduced, and efficiency is improved.
Furthermore, a flexible shielding curtain is arranged at the top of one end, away from the crushing box body, of the feeding channel, and the end of the feeding channel is shielded by the shielding curtain when the shielding curtain naturally hangs down. Although a longer feeding channel is arranged to enable dust to settle in the feeding pipeline, the air always flows, and a small amount of dust inevitably flies into the outside air, and a shielding curtain is arranged to shield the dust in order to further reduce the dust content in the outside air.
Furthermore, the top of the crushing box body is provided with a dust raising port which is communicated with a dust collecting pipeline. The mass of dust is lighter, and it is easier to go upwards, so set up raise dust mouth at the top of crushing box, the dust volume of collecting from raise dust mouth is bigger, so the volume of centralized processing is also big.
Further, the dust purification tank include jar body and with jar water filling port of body intercommunication, jar body top is equipped with the gas outlet, the bottom of jar body is the infundibulate, and jar body bottom is equipped with the drain, drain department is equipped with the drain valve. The water state is kept in the funnel-shaped bottom of the tank body, the dust collecting pipeline is positioned below the liquid level, and the funnel-shaped bottom of the tank body is arranged, so that dust dissolved into water is favorably settled, and the dust is collected in a centralized manner and is convenient to drain.
Furthermore, the water injection port is communicated with the top of the tank body, a plurality of horizontal water-stop plates are arranged in the tank body, the water-stop plates are arranged in a staggered mode from top to bottom, a water flowing port is arranged between each water-stop plate and the inner wall of the tank body, and one water flowing port corresponds to the position right above each water-stop plate. Such design makes the water filling port position be higher than the water proof sheet of the top, and the water that flows into the jar internal from the water filling port can flow through each water proof sheet with this, and the water of every water proof sheet flows down from the discharge orifice and forms cascade or water curtain, and the water proof sheet sets up in the crisscross simultaneously for the dusty air flows the in-process bending flow that makes progress, has prolonged the flow distance, and all obtains washing of water through the cascade at every turn, and dust removal effect is better.
Furthermore, a plurality of water holes are uniformly distributed on each water-stop plate from the second water-stop plate above to the lowest water-stop plate. Under the continuous water flow of the water holes, the dust-containing air can be flushed by water in the flowing process, and the purification effect is best.
