Description

TECHNICAL FIELD

[0001] The application relates to the technical field of semi-coke production, and particularly discloses a raw material crushing device for semi-coke production. BACKGROUND

[0002] Semi-coke is a high-efficiency and environment-friendly coal substitute, which is usually made of high-quality anthracite or lump coal with low ash content through dry distillation. The main components of semi-coke are fixed carbon, volatile matter, and a small amount of ash and sulfur. The fixed carbon content of semi-coke is as high as 80% or more, and the volatile matter is less than 10%, so that semi-coke has the characteristics of high calorific value and low pollution, and is widely used in the chemical industry, smelting, gas making and other industries.

[0003] In the production process of semi-coke, the raw coal is first crushed into small pieces, and then the crushed raw coal is sent into a carbonization furnace for carbonization treatment. In the carbonization process, the raw coal undergoes stages of drying, pyrolysis, coking and graphitization, and generates semi-coke and raw coal gas. Finally, the carbonized semi-coke is cooled and screened, and the semi-coke product is obtained.

[0004] However, in the process of crushing the raw coal, a large amount of dust is generated due to the friction, impact of the coal blocks with the crushing machinery and the mutual collision between the coal blocks. The dust not only pollutes the production environment, but also threatens the health of the workers. At present, the dust in the process of crushing the raw coal is usually blocked by a cover plate at the feeding port of the crusher, which can effectively reduce the overflow of dust in the process of crushing the raw coal. However, when the cover plate is opened after crushing to feed the next batch of raw coal, some dust will still overflow from the feeding port, polluting the surrounding production links and threatening the health of the workers.

[0005] Therefore, the inventors provide a raw material crushing device for semi-coke production to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at solving the problem that in the process of crushing the raw coal, part of the dust overflows from the feeding port of the crusher, pollutes the surrounding production links and threatens the health of the workers.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a raw material crushing device for semi-coke production, which comprises a shell, a crushing assembly arranged in the shell and used for extruding and crushing the raw coal, and a driving member used for driving the crushing assembly.

[0008] The top and bottom of the shell are respectively provided with a feeding port and a discharging port. The inner wall near the feeding port in the shell is hingedly connected with a hinge plate which is turned inside the shell. The side surface of the hinge plate facing the inside of the shell is uniformly provided with a plurality of spray heads. The outside of the shell is provided with a water inlet pipeline which is in communication with the spray heads.

[0009] The principle and effect of the basic scheme are:

[0010] Compared with the prior art, the utility model discloses a hinge plate is arranged in the shell and is turned to the inside of the shell, so that when raw coal is loaded, the gravity of raw coal drives the hinge plate to rotate to enter the shell for crushing, without disassembling or manually opening the hinge plate, raw coal loading is more convenient, and a spray head is arranged on the hinge plate, so that the spray head carries out water spraying treatment in the process of raw coal crushing, dust overflow is avoided, and the problem that in the process of traditional raw coal crushing, part of dust overflows from the feeding port of the crusher, pollutes surrounding production links and threatens the health of workers is solved.

[0011] Further, the shell is also provided with a baffle, the baffle is located on the side of the hinge plate towards the inside of the shell, and the spray head faces the hinge plate. Through the arrangement of the baffle, not only can the water flow sprayed by the spray head flow along the baffle and flow down in the form of a waterfall surface to better absorb and block dust, but also the impact of the water flow on the baffle causes the spray head and the hinge plate to be subjected to the reaction force of the water flow, thereby improving the fitting effect of the hinge plate and the inner wall of the shell and reducing the gap between the hinge plate and the inner wall of the shell, so as to further avoid dust overflow.

[0012] Further, the mounting surface perpendicular to the inner wall of the feeding port is arranged at the connection between the inner wall of the shell and the feeding port, and the hinge plate is hinged to the mounting surface. In order to facilitate the installation of the hinge plate.

[0013] Further, the mounting surface is symmetrically provided with hinge ears, a hinge shaft is arranged between the hinge ears, one end of the hinge plate is provided with a hinge sleeve sleeved on the hinge shaft, and a torsional spring is arranged between the hinge shaft and the hinge sleeve. The torsional spring can reset the hinge plate in time after turning over, thereby improving the fitting effect of the hinge plate and the inner wall of the shell.

[0014] Further, the hinge plate comprises a plurality of hinge plates connected in sequence. This arrangement facilitates the passage of raw coal into the shell.

[0015] Further, the water inlet pipeline and the spray head are respectively provided with wrinkle pipelines or soft pipelines that can be lengthened and shortened and bent. The arrangement of the wrinkle pipelines or soft pipelines can avoid the rupture of the connection between the water inlet pipeline and the spray head during the rotation of the hinge plate, thereby preventing water leakage.

[0016] Further, the crushing assembly comprises an extrusion roller rotatably connected in the shell and an extrusion plate arranged in the shell, an extrusion gap is formed between the extrusion roller and the extrusion plate, and the side wall of the extrusion roller is uniformly provided with a plurality of hammer blocks. The hammer blocks are rotated by the extrusion roller in the rotating process, so that the hammer blocks extrude the raw coal in the extrusion gap, thereby achieving the effect of crushing the raw coal.
