Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to a calcium carbonate ore crusher. Background Art

[0002] Calcium carbonate ore is a mineral resource whose main component is calcium carbonate (CaCO3). This ore has a wide range of applications in industry, including but not limited to building materials, papermaking, coatings, plastics, chemicals, medicine, food and environmental protection. Due to its rich calcium resources, calcium carbonate ore plays an important role in many industries. After mining, calcium carbonate ore needs to be crushed.

[0003] The existing crushers perform crushing processing by means of crushing rollers, on which crushing teeth are arranged. However, the crushing teeth and the crushing rollers are an integrated structure. Therefore, when the crushing teeth are worn or damaged, the entire crushing roller may need to be replaced, increasing maintenance costs and work downtime. In addition, a large amount of dust is generated in the process of crushing the calcium carbonate ore, which will not only spread to the surrounding environment and pollute the air and soil, but also may cause dust accumulation and blockage of the equipment, affecting the normal use of the equipment. Utility Model Content

[0004] The utility model aims to provide a calcium carbonate ore crusher which is convenient for replacing crushing teeth, reduces maintenance costs and work downtime, and reduces the impact of dust.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A calcium carbonate ore crusher comprises a bottom plate, a shell is installed on the upper surface of the bottom plate, a pair of crushing rollers are rotatably installed inside the shell through a driving mechanism, mounting grooves are evenly provided on the outer surface of the crushing rollers, mounting plates are provided inside the mounting grooves, and crushing teeth are evenly installed on the outer surface of the mounting plates. A limiting groove is provided on the lower surface of the mounting plate along its length direction, a limiting rod is provided inside the mounting groove, and the limiting rod is matched with the limiting groove, and a fixing mechanism capable of fixing the mounting plate is provided on the side surface of the crushing roller.

[0007] It can be seen that the purpose of crushing calcium carbonate ore can be achieved by driving the two crushing rollers to rotate through the driving mechanism. The setting of the fixing mechanism makes it easy to disassemble and assemble the mounting plate. Therefore, when the crushing teeth are worn or damaged, only the mounting plate with the crushing teeth installed needs to be replaced, and there is no need to replace the entire crushing roller, thereby reducing maintenance costs and work downtime, which is beneficial to the production and operation of the enterprise. In addition, the crushing roller can be replaced with crushing teeth of corresponding models according to the types of crushed objects, thereby expanding the scope of use of the device.

[0008] Furthermore, the driving mechanism includes a driving motor installed on the outer surface of the shell, a first pulley is installed on the end of the output shaft of the driving motor, a second pulley is rotatably installed on the outer surface of the shell, and the second pulley is connected to one of the crushing rollers, the outer surfaces of the first pulley and the second pulley are jointly meshed with a transmission belt, and two transmission gears are rotatably installed on a side of the shell facing away from the second pulley, and the two transmission gears are respectively connected to the two crushing rollers, and the two transmission gears are meshed with each other.

[0009] When the driving motor is started, its output shaft drives the first pulley to rotate, and through the transmission action of the transmission belt, the crushing roller connected to the second pulley can be driven to rotate, and one of the transmission gears can be driven to rotate. Because the two transmission gears are meshed with each other, the two crushing rollers can rotate at the same time, thereby achieving the purpose of crushing the calcium carbonate ore.

[0010] Furthermore, the fixing mechanism includes a fixing block installed on the side surface of the crushing roller, a telescopic rod is installed on the outer surface of the fixing block, an insert block is installed on the end of the telescopic rod, a spring is sleeved on the outer surface of the telescopic rod, and the two ends of the spring are respectively abutted against the fixing block and the insert block, a slot is opened on the lower surface of the mounting plate, and the insert block is adapted to the slot.

[0011] When the crushing tooth is worn or damaged and needs to be replaced, the insert block can be pushed downward to compress the spring so that its end is pulled out of the slot. At this time, the mounting plate loses its fixation and the mounting plate can be pulled out of the mounting slot. Then, the new mounting plate is inserted horizontally into the mounting slot and the limit rod is inserted into the limit slot. The limit rod and the limit slot can limit the mounting plate. Then, the insert block is reinserted into the slot to fix the mounting plate, thereby completing the rapid replacement of the mounting plate and realizing the replacement of the crushing tooth.

[0012] Furthermore, multiple dust suction tubes are connected to both side surfaces of the shell near its upper end, a first connecting tube is commonly installed at the ends of the multiple dust suction tubes, the ends of the two first connecting tubes are commonly connected to a second connecting tube, a fan is installed on the upper surface of the base plate, a bellows is connected to the suction end of the fan, the end of the bellows is connected to the second connecting tube, and a dust collecting bag is connected to the output end of the fan.

[0013] During the crushing of calcium carbonate ore, the fan is started, and the suction force generated by the fan acts on the dust suction pipe. The dust can be sucked away by the suction force at the end of the dust suction pipe during the process of floating upward, and is finally discharged into the dust collecting bag for collection through the first connecting pipe, the second connecting pipe and the bellows, thereby reducing the diffusion of dust to the surrounding environment, providing a good working environment for the work site, and through the setting of the bellows, the vibration generated during the crushing process can be prevented from affecting its structure.

[0014] Furthermore, a filter is provided at the connection between the dust suction pipe and the shell, and the filter is made of stainless steel.

[0015] The setting of the filter can prevent small fragments from flying into the dust collection pipe during the crushing process, thereby preventing the fan from being damaged.

[0016] Furthermore, a push block is installed on the outer surface of the insert block.

[0017] By setting the push block, a force point can be provided, which facilitates the pushing operation of the slot.

[0018] Furthermore, an inspection door is provided on the outer surface of the shell.

[0019] When replacing the mounting plate, the inspection door can be opened and the mounting plate can be replaced through the inspection door without large-scale dismantling of the entire shell, thereby improving the inspection efficiency.

[0020] Furthermore, four dust suction pipes are connected to both sides of the shell near its upper end, and the four dust suction pipes are equidistantly distributed.

[0021] By setting up four dust suction pipes, the dust suction range can be expanded and the dust escape can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS
