A high-efficiency crushing device for coal block for coal processing

Abstract

The invention discloses an efficient coal briquette crushing device for coal processing. The crushing device comprises a crushing chamber, and the crushing chamber is of a U-shaped structure; a horizontal plate is horizontally connected between the feeding ports, and a first motor is arranged on the horizontal plate; a longitudinal sliding block is arranged in a longitudinal sliding way in a sliding mode, a transverse sliding block is arranged in a transverse slide way in a sliding mode, and the upper end of a horizontal push rod is hinged to the longitudinal sliding block; a crushing cavity communicating with discharging passages is arranged in the crushing chamber, and the lower end of a longitudinal pushing rod is positioned in the crushing cavity; two hanging brackets are symmetricallyarranged on the lower surface of a bottom plate relative to the longitudinal push rod; the upper ends of rotating rods are hinged to the lower end of the longitudinal push rod; and a rotating shaft is coaxially and fixedly installed on an output shaft of a second motor, and the rotating shaft extends upwards into the crushing cavity. According to the efficient coal briquette crushing device, coalbriquettes entering the crushing chamber through the feeding ports are subjected to transverse impact crushing of impact hammers, then subjected to repeated knocking of knocking blocks and finally subjected to rotary crushing of spiral blades, and therefore the coal briquettes can be fully crushed and refined through the three time crushing effects.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to an efficient coal crushing device for coal processing. Background technique [0002] Coal, referred to as coal, is the remains of ancient plants, buried under the stratum, and subjected to the pressure and temperature of the crust to isolate the air, resulting in carbonized fossil minerals, black solid minerals composed of carbon, hydrogen, oxygen, nitrogen and other elements, mainly Mined by humans for fuel. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. Coal has been widely used as a fuel for industrial production since the industrial revolution at the end of the 18th century. With the invention and use of steam engines, coal has been widely used as a fuel for industrial production, bringing unprecedented productivity to society. [0003] Due to the large volume of ...

Problems solved by technology

[0003] Due to the large volume of the coal mined from the coal mine, it is necessary to crush and refine the coal during the production and processing of coal to facilitate subsequent production operations. The existing coal crushing device does not have a good crushing effect on the coal , usually only through a single crushing action, the crushing efficiency is low, and it is difficult to completely crush and refine the coal block
