Description

Energy-conserving lime stone breaker
Technical Field
The invention relates to the technical field of mining machinery, in particular to an energy-saving limestone crushing device.
Background
Lime ore is calcined to form quicklime, the component of the quicklime is calcium oxide, which is a common building material and is also a main raw material for processing cement, generally, before limestone is used, the limestone needs to be crushed to facilitate transportation and reduce dust generation, and only the limestone needs to be crushed into small particles and then is subjected to crushing, grinding and other processes before the limestone is produced into cement. The existing limestone crushing equipment does not consider the arrangement of dust removal, so that the environment of the whole lime kiln is often very poor, and serious pollution is caused; some production machines have adopted the mechanism that removes dust in time now, generally have the mode that water smoke removed dust and negative pressure removed dust, because the lime stone composition is calcium oxide, if adopt water smoke to remove dust and can cause a large amount of steam, the calcium hydroxide that generates simultaneously has strong corrosivity, and equipment part of be suffers often to corrode and damage. Although the way of negative pressure is adopted to avoid the contact reaction of excessive moisture and quicklime. Each part in the crushing device can produce and leave a large amount of deposited dust (limestone powder), if the device is placed for a long time, limestone can react with water and carbon dioxide in the air to generate calcium salts with strong adhesive force such as calcium carbonate, and parts in the crushing device can be blocked, such as a sieve plate in the crushing device, so that the produced parts are unqualified in the next work, and even mechanical parts are damaged.
Disclosure of Invention
The problem of residual limestone dust accumulation in the crushing device in the prior art is serious, so that the crushing device is difficult to normally work is solved.
The application provides an energy-saving limestone crushing device which comprises a machine shell, a crushing roller and a negative pressure fan, wherein a feed port is formed above the machine shell, and a dust removal port is formed below the machine shell; broken rod sets up inside and being located the dog-house under the casing, negative-pressure air fan installs at the dust removal mouth, broken rod both sides and below are provided with screening mechanism, screening mechanism is including adopting the steel foil to make to have elastic screening net, the inside rotatory rod that passes through mount fixed connection that is equipped with of casing, the transmission of screening net is connected at rotatory rod surface, and screening net and rotatory rod form U type transfer passage, and rotatory rod surface is provided with the clearance post that agrees with the mesh of screening net, be connected with a plurality of screening nets on the rotatory rod side by side, be provided with the cutter between the adjacent screening net, the cutter is fixed on rotatory rod surface.
The application discloses energy-conserving lime stone breaker's theory of operation does: during the operation of the device, the fan is started, large limestone is put into the feed opening of the shell, the limestone crushed by the crushing roller is split and packaged by adding limestone particles through the discharge opening on the shell when the particle size is satisfied and the particle size is generally the best at five square millimeters; limestone smaller than the particle size is screened to the next outlet, and the negative pressure fan is used for collecting dust under the action of negative pressure, so that the dust enters the collecting bag, and the environment of the whole crushing operation is ensured.
The application discloses energy-conserving lime stone breaker's advantage lies in: 1. a screening net is arranged below the crushing roller and can move under the action of a rotating roller, so that when the screening net is hardened, the rotating roller drives the screening net to move, and particles attached to the screening net are cleaned in the reverse process; 2. rotatory rod surface is provided with the clearance post that agrees with the mesh of screening net, when the lime stone card that hardens passes the mesh through the clearance post and just can realize the clearance when the mesh, 3 in order to prevent the massive circumstances that hardens that appears on the sieve, this application will shine the net and divide into many, sets up the cutter between every, will harden like this and be cut into the fritter to the board knot thing can drop smoothly.
Further, in order to collect dust collected by the negative pressure fan, a clamping pipe is arranged on the machine shell below the negative pressure fan, and a clamping edge is arranged on the outer surface of the clamping pipe; when the dust collecting clamping pipe works, a cloth bag or other filter bags for collecting dust are fixed on the clamping pipe, and the clamping ribs arranged on the outer surface of the clamping pipe effectively prevent the cloth bag or the filter bags from falling.
Furthermore, after the equipment is placed for a period of time, because limestone dust and carbon dioxide and water in the air can produce calcium carbonate, the calcium carbonate is hardened in the equipment and blocks the sieve pores, in order to clean the hardened calcium carbonate in the crushing device, a waste material collecting plate is arranged below the sieving net, and two sides of the waste material collecting plate are connected to the inner wall of the machine shell in a sliding manner; when the waste collection plate needs to be cleaned, the waste collection plate is pushed into the machine shell; the scrap collecting panel is extracted if it is broken normally.
Furthermore, the crushing roller comprises two main rollers and a disturbance roller, the disturbance roller is arranged below the two main rollers, the two main rollers are respectively meshed with the disturbance roller gear in a single direction through a ratchet wheel, the two main rollers are both connected with a motor, the disturbance roller is provided with a belt pulley, and the belt pulley is in transmission with the two main rollers through a belt; wherein the idle running direction of the ratchet wheel is the same as the driving direction of the disturbing roller through the belt. The advantages of this arrangement are: when one of the main sticks drives the disturbing stick, the other main stick is driven by the disturbing stick and does not bear load, and vice versa; therefore, the alternate operation can reduce the loss of the main stick. 2. The disturbance wheel sets up the effect that plays the support limestone in two main rod below for the limestone rotates on the disturbance rod, makes limestone energy surface broken gradually like this, to the damage of broken tooth in the time of with the reduction breakage.
Furthermore, the two main rods and the disturbance rods are provided with crushing teeth, so that the three rods are crushed simultaneously, and the crushing efficiency is improved.
Finally, in order to facilitate the maintenance and management of the fan, the fan is independently hinged on the dust removal port; like this if the fan appears the blade and damages, sister can slide out the fan from the side, change can, unnecessarily dismantle whole equipment.
