Description

Technical Field

[0001] The utility model relates to the technical field of magnesite processing, in particular to a crushing and separation device for magnesite processing. Background Art

[0002] Magnesite is a carbonate of magnesium. Magnesite often contains iron, manganese, calcium, etc. Its color ranges from white to slightly yellow, blue, red, gray, and even brown-black. According to the different crystal states, it can be divided into crystalline magnesite and amorphous magnesite. Magnesite needs to be crushed after mining to facilitate the subsequent dissolution and purification production. In the process of crushing, different sizes often appear, which leads to different dissolution rates during subsequent dissolution, affecting production. For this reason, it is necessary to separate the crushed magnesite. The existing separation device is separated from the crushing device, which wastes time and cannot meet the needs of use.

[0003] For example, Chinese patent announcement No. CN218637450U discloses a magnesite crushing and separation. When in use, the magnesite is placed inside a feed pipe. If the magnesite is large, a hydraulic rod is used to push an extrusion plate to perform preliminary crushing on it. After crushing, it is introduced to the top of a crushing roller through a first guide plate, and crushing is achieved with the cooperation of the crushing roller and crushing teeth. After crushing, it is screened through a screen vibrated by a vibration motor. The large ones are discharged through a discharge pipe, and the small ones are introduced to the top of a conveyor belt through a second guide plate and discharged through the conveyor belt.

[0004] However, the magnesite crushing and separation in the above application, after the magnesite is crushed, the crushed ore is passed through a screen for screening and separation, but the crushed ore may clog the screen, thereby affecting the screening work, therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a crushing and separation device for magnesite processing. Utility Model Content

[0006] The purpose of the utility model is to provide a crushing and separation device for magnesite processing, so as to solve the problem of magnesite crushing and separation proposed in the above-mentioned background technology. After the magnesite is crushed, the crushed ore is passed through a screen for screening and separation, but the crushed ore may clog the screen, thereby affecting the screening work.

[0008] The separation device comprises a screening unit, a vibration unit, a driving unit and a scraping unit.

[0009] The screening unit includes a screening plate, a mounting bin, and a vibration spring. The screening plate is installed in the middle part of the separation box. The four mounting bins are respectively opened in the four corners of the middle part of the separation box. Four groups of vibration springs are respectively fixedly connected to the upper and lower sides of the four corners of the screening plate in groups of two, and are installed in the interior of the mounting bin. The crushed ore falls onto the screening plate, and the ore that meets the specifications directly passes through the screening plate, thereby completing the separation and screening of the ore.

When the ore falls onto the screening plate, the vibration motor is started to drive the rotating shaft to rotate, which in turn drives the striking plate to rotate and hit the screening plate, causing the screening plate to vibrate up and down on the vibration spring, thereby facilitating rapid separation and screening of the ore.

[0011] A further improvement is that the drive unit includes a drive motor, a transmission member, a limit rod, and a sliding sleeve. The drive motor is installed at the rear end of the right outer surface of the separation box, the transmission member is connected to the output end of the drive motor, the limit rod is fixedly connected to the internal front end of the separation box, and the sliding sleeve is slidably connected to the limit rod.

[0012] A further improvement is that the scraper unit includes a connecting rod and a scraper plate, the front and rear ends of the connecting rod are respectively fixedly connected between the transmission member and the sleeve, and the scraper plate is fixedly connected to the bottom of the connecting rod. When unqualified ore accumulates on the screening plate, the drive motor is started to drive the screw in the transmission member to rotate, thereby driving the threaded sleeve on the screw to move, and because a connecting rod is connected between the threaded sleeve and the sleeve, the scraper plate at the bottom of the connecting rod is driven to move from right to left to scrape off large pieces of ore, thereby preventing the screening plate from being blocked and affecting the separation and screening effect.

[0013] A further improvement is that a discharge port is provided on the left outer surface of the separation box, a discharge pipe is fixedly connected to the bottom of the separation box, and screening holes are evenly provided on the upper surface of the screen plate. The separation and screening of the ore are achieved through the screening holes, and the large pieces of ore on the screen plate are scraped off to the discharge port for discharge, while the ore that meets the specifications after separation is discharged from the discharge pipe.

[0014] A further improvement is that the crushing device includes a crushing motor, a crushing shaft, a gear, and a crushing knife group. The crushing motor is installed at the rear end of the right outer surface of the crushing box through a mounting seat. The two crushing shafts are rotatably connected to the front and rear sides of the crushing box through sealed bearings, and the right end of the rear end crushing shaft is connected to the output end of the crushing motor. The two gears are fixedly connected to the right end of the outer surface of the crushing shaft, and the two are meshingly connected. The two crushing knife groups are fixedly connected to the outer surface of the crushing shaft. Starting the crushing motor drives the rear end crushing shaft to rotate, and then drives the gear on it to rotate, meshing and rotating with the gear on the outer surface of the front end crushing shaft, thereby driving the crushing knife groups on the two crushing shafts to rotate, thereby crushing the ore.

[0015] A further improvement is that a controller is installed on the left side of the front of the separation box, and the separation device and the crushing device are electrically connected to the controller, and the operation of the device is controlled by the controller.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The crushing and separation device for magnesite processing, when the crushed ore falls onto the screening plate, starts the vibration motor to drive the rotating shaft to rotate, and then drives the striking plate to rotate and hit the screening plate, so that the screening plate vibrates up and down on the vibration spring, which is convenient for rapid separation and screening of the ore.

[0018] 2. When unqualified ore accumulates on the screening plate, the driving motor is started to drive the screw in the transmission part to rotate, thereby driving the threaded sleeve on the screw to move. Because a connecting rod is connected between the threaded sleeve and the sleeve, the scraper plate at the bottom of the connecting rod is driven to move from right to left to scrape off large pieces of ore, thereby preventing the screening plate from being blocked and affecting the separation and screening effect.
