Description

Technical Field

[0001] This utility model relates to the technical field of crushing and mixing devices, specifically a crushing and mixing device for environmentally friendly coal production. Background Technology

[0002] Environmentally friendly coal, also known as low-emission coal, refers to coal that has undergone special treatments such as washing, dehydration, and desulfurization. Compared with traditional raw coal, environmentally friendly coal has advantages such as higher calorific value and lower ash and sulfur content. Environmentally friendly coal is a green and environmentally friendly fuel choice and is widely used in power generation, metallurgy, chemical and other industries. Currently, with the increasing awareness of environmental protection, the market demand for environmentally friendly coal is gradually increasing. After the environmentally friendly coal is produced, it needs to be crushed to facilitate its use. In order to better crush environmentally friendly coal, a crushing and mixing device for the production of environmentally friendly coal is proposed.

[0003] For example, the environmentally friendly coal production crushing and mixing device disclosed in the authorization announcement number CN209271363U includes a base, the bottom of which is fixedly connected to multiple support rods, and the top of which is fixedly connected to a fixing plate via a fixing rod;

[0004] Although it achieves the coordinated action of the power mechanism, the second connecting mechanism, the third connecting mechanism, the second rotating shaft and the third rotating shaft, the motor drives the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft to rotate through the meshing of the first helical gear and the second helical gear. The second rotating shaft, through the meshing of the first gear and the second gear, drives the crushing teeth on the third rotating shaft and the crushing teeth on the second rotating shaft to crush the coal blocks relative to each other. Through the synergistic action of the base, the first connecting mechanism, the turntable, the mixing box and the mixing block, the first rotating shaft drives the pulley to rotate, which in turn drives the mixing box to rotate. At the same time, the mixing block is used to crush the crushed coal blocks a second time, and the turntable is used to assist the rotation of the mixing box.

[0005] However, the existing crushing and mixing device does not solve the problem that it is not convenient to mix and crush environmentally friendly coal in use, nor is it convenient to screen and classify the crushed environmentally friendly coal for output, and it affects the convenience of cleaning coal slag on the inner wall of the mixing box.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly coal crushing and mixing device, comprising an integrated frame and a filter box. The filter box is installed inside the integrated frame, and a crushing box is installed inside the integrated frame above the filter box. A mixing box is installed at the top of the integrated frame, and the bottom of the mixing box is connected to the crushing box. A feed inlet is installed at the top of the mixing box.

A movable shaft is symmetrically and movably installed inside the crushing box. Crushing rollers are fitted onto the surface of each movable shaft inside the crushing box, and crushing gears are fitted onto the surface of each movable shaft outside the crushing box. Two sets of crushing gears mesh with each other. A support block is installed on the outer wall of the integrated frame, and a crushing motor is installed at the top of the support block. The output end of the crushing motor is connected to a set of movable shafts.

[0008] Preferably, threaded rods are symmetrically installed on the inner wall of the mixing tank, and the threaded rods are movably connected to the mixing tank.

[0009] Preferably, a movable motor is installed on the outer wall of the mixing tank on both sides of the stirring motor, and the output end of the movable motor is connected to the threaded rod.

[0010] Preferably, the surface of the threaded rod is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the threaded rod. The threaded sleeve is also slidably connected to the mixing tank. A scraper is installed on the side wall of the threaded sleeve, and the scraper is slidably connected to the inner wall of the mixing tank.

[0011] Preferably, the filter box is provided with a mesh filter barrel inside, and multiple sets of equally spaced limiting wheels are symmetrically and movably installed on the inner wall of the filter box. The limiting wheels are slidably connected to the mesh filter barrel, and the mesh filter barrel is connected to the bottom of the crushing box.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the crushing and mixing device not only realizes convenient mixing and crushing of environmentally friendly coal, and facilitates the screening, classification and output of the crushed environmentally friendly coal, but also improves the convenience of cleaning coal slag on the inner wall of the mixing box.

[0016] (1) By feeding environmentally friendly coal into the mixing tank through the inlet, the mixing motor drives the linkage shaft to rotate, which in turn drives the pressure rod and threaded blades to rotate. The threaded blades transport the environmentally friendly coal from the right end of the mixing tank to the left end and drop it into the crushing tank. At the same time, the pressure rod applies a downward force to the environmentally friendly coal, allowing the crushing rollers to crush it more effectively. The crushing motor drives a set of crushing gears and crushing rollers to rotate through a set of movable shafts. One set of crushing gears drives another set of crushing gears to rotate, which in turn drives another set of movable shafts and crushing rollers to rotate. Under the interaction of the two sets of crushing rollers, the environmentally friendly coal is crushed and discharged from the crushing tank. The crushed coal is fed into the mesh filter barrel. The drive motor drives the drive shaft to rotate, which in turn drives the drive gear. The drive gear, through the gear ring, drives the mesh filter barrel to rotate inside the filter box. The limit wheel provides limit support for the mesh filter barrel. Small particles of environmentally friendly coal leak out through the holes on the surface of the mesh filter barrel and are output from the bottom of the filter box. Large particles of environmentally friendly coal are guided by the guide bar and discharged from the inside of the mesh filter barrel through the discharge tray. This process screens and classifies the crushed environmentally friendly coal, realizing convenient mixing and crushing of environmentally friendly coal, facilitating the screening and classification of the crushed environmentally friendly coal, and improving the convenience of use.

[0017] (2) After the environmentally friendly coal is crushed, the inner wall of the mixing box will be covered with coal slag. The moving motor drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move from right to left, and the threaded sleeve drives the scraper to move. With the sliding cooperation between the scraper and the mixing box, the scraper scrapes and cleans the coal slag on the inner wall of the mixing box, thereby improving the convenience of cleaning.
