A screw-type centering adjustment method for a double-toothed roller crusher

Abstract

The invention relates to a screw rod centering method and a device of a double-geared roller crusher and belongs to the technical field of adjustment of the double-geared roller crusher. The invention adopts the technical scheme that a crushing system adjustment device is in an eccentric cup structure; a support plate is square; a lead screw nut mechanism is arranged at each of four corners; each lead screw nut mechanism consists of screw rods (1), a support plate (2), lock nuts (3), lower nuts (7), upper fixing nuts (4) and lower fixing nuts (5); a base (6) is fixed; and a plurality of strip-shaped mounting holes (8) are formed in the support plates. According to the method and the device, a horizontal center distance between two rollers of a crushing system is adjusted by adjusting the eccentric cup structure; free ascent and descent of the support plates is achieved by a lead screw adjustment structure; a horizontal position of a motor or a speed reducer is adjusted via the strip-shaped mounting holes, so as to achieve center height centering jointly; on-site particle size adjustment difficulty is reduced; overhaul time is shortened; and further, stable operation and a rated service life of the double-geared roller crusher are ensured.

Description

technical field [0001] The invention relates to a screw-type centering adjustment method of a double-toothed-roll crusher, belonging to the technical field of double-toothed-roll crusher adjustment. Background technique [0002] In the past ten years, large-scale mechanized mining of coal has realized large-scale centralized washing. High-efficiency clean coal technology needs to improve the production automation level and equipment large-scale level of washing equipment at the same time to improve washing efficiency. Crushing equipment is the necessary throat equipment for coal washing plants. Double-toothed roller crushers are widely used in major washing plants due to their obvious advantages such as simple manufacture, low energy consumption, convenient maintenance, low cost, and high crushing capacity. The double-toothed roller crusher crushes the material through the shearing, stretching and extrusion of the crushing teeth. After crushing for a certain period of time,...

Problems solved by technology

By rotating the eccentric cup, the center distance of the crushing roller can be adjusted to increase or decrease, but at the same time, it will also cause a change in the vertical height, and its center height will also change with its rotation. The double-toothed roller crusher motor reducer They are all fixed on the equipment base at the same level, and the horizontal movement is simple and easy, but the vertical movement needs to increase or decrease the backing plate, and the thickness of the backing plate must be processed according to the actual size of the alignment, which requires a relatively long maintenance time and Relatively professional fitter quality

The on-site production tasks are heavy and the maintenance time is tight. Therefore, after the particle size adjustment, it is necessary to re-align the equipment and process and replace the backing plate of the reducer, which greatly increases the difficulty of particle size adjustment of the crusher. Factors such as the quality of the maintenance workers and the processing conditions of the equipment determine the difficulty of adjusting the particle size of the eccentric cup structure, which brings inconvenience to the use site
