Description

Single-drive double-geared roller crusher suitable for long and narrow space and convenient to assemble on site

Technical Field

The invention relates to the field of crushers, in particular to a single-drive double-geared roller crusher which is applicable to a long and narrow space and convenient to assemble on site.

Background

At present, the double-geared roller crusher is widely applied to the field of ore and coal crushing. Generally, a double-toothed roller crusher includes a base, a casing, a driving part, a pair of crushing toothed rollers, and the like. The double-geared roller crusher is divided into a double-drive crusher and a single-drive crusher according to the number of the drive motors. Wherein, two fluted rollers of the double-drive double-fluted roller crusher are driven by an independent driving part to rotate relatively, only one fluted roller of the single-drive double-fluted roller crusher is driven by the driving part, and gear transmission is adopted between the two fluted rollers so as to ensure synchronous relative rotation. The driving part is usually composed of a motor and a reducer, etc., or a motor and a belt transmission reducing mechanism, the latter generally occupies a larger width space. In general, two sets of driving parts are symmetrically arranged in the width direction of the double-drive double-geared roller crusher, so that the width of the double-drive crusher is larger. In order to ensure certain strength, the base and the box body are designed and manufactured into a whole, if the base and the box body are welded into a whole box body, the left baffle plate and the right baffle plate of the box body are integrally designed with a bearing seat for supporting the crushing toothed roller. According to the design scheme, the size and the weight of the base and the box body part of the crusher are large.

The Chinese patent with publication number CN104069913B, a double-geared roller crusher, has two sets of driving units symmetrically arranged in parallel at one end of the crusher, each set of driving unit comprises a motor and a speed reducer; as can be seen from the figures, the width of the driving part of the crusher exceeds the size of the crushing part.

The Chinese patent application with the publication number of CN102921499A, namely a novel toothed roller type coal crusher, and the Chinese patent application with the publication number of CN213825049U, namely a double-roller crusher, wherein two sets of transmission parts are adopted in the two patents and are respectively arranged at the two ends of the crusher, and each set of transmission system transmits the power of a motor to one of the crushing toothed rollers through belt transmission; with the arrangement, the two ends of the crusher are provided with the transmission parts, so that the length of the crusher is not reduced, but the width of the crusher is increased to a certain extent.

Generally, after the double-geared roller crusher is assembled and debugged in a production workshop, the whole crusher is transported to a working site and installed for use, and the external dimension of the crusher and the structures and weights of all parts are not limited too much in the condition. However, in some use occasions, the space of the installation position of the crusher is narrow and long, the width and the height are both limited, and the whole hoisting can not be carried out by using heavy equipment. Therefore, the crusher is required to be designed to satisfy a long and narrow working space and to be modularly designed so as to facilitate on-site assembly and later maintenance and repair.

Thus, the double-geared roller crusher 1000 of the present invention receives a material through the feeding chute 2000, and discharges the crushed material through the discharging chute 3000 after crushing.

In order to better satisfy the production requirements, the production system needs to be modified, and one link in the technical modification scheme is to install a double-geared roller crusher on an installation platform 4000 beside a scraper conveyor 6000 in front of a medium removing screen 5000 in fig. 10. The double-geared roller crusher crushes materials falling from a 5000-mesh screen of the disjointed screen and then discharges the crushed materials into a material mixing barrel 7000 below the mounting platform 4000; the space of the positions in which the double-toothed roller crusher is to be installed is drawn by a box filled with diagonal lines and marked with the letter I.

As can be seen from FIG. 10, the space I where the double-geared roller crusher can be installed is very narrow and narrow, and has severe requirements on parameters of the width and the height of the crusher; because numerous devices are installed on the periphery, the double-geared roller crusher cannot be hoisted to the installation position completely, and the installed double-geared roller crusher can only be assembled on site. The embodiment of the invention shown in figure 1 is used according to the production process requirements of the retrofit and the constraints of the field installation space.

Fig. 11 is a layout of equipment of a production system after installation of a crusher according to an embodiment of the present invention, and fig. 12 is a left side view of the layout of the equipment in fig. 11. As can be seen from fig. 11 and 12, the double-tooth-roller crusher 1000 according to the embodiment of the present invention is arranged at the block I shown in fig. 10, and the upper connecting flange 44 of the box body 4 of the double-tooth-roller crusher 1000 is connected to the lower opening of the feeding chute 2000, and the upper opening of the feeding chute 2000 is connected to the screen 5000, so as to guide the oversize material into the double-tooth-roller crusher 1000; the discharge opening 11 of the double-geared roller crusher 1000 is connected to a discharge chute 3000 below to guide the crushed material into the mixing barrel 7000.

When the double-toothed-roller crusher 1000 is installed, the rack 1 is firstly transported to the installation platform 4000 and fixedly connected with the installation platform 4000, then the supporting seat 2 is transported to the installation platform 4000, the supporting seat base 21 is connected with the rack 1, and then the driving toothed roller 31 and the driven toothed roller 32 of the pair roller assembly 3 are erected on the supporting hole 23 on the supporting seat base 21 and then connected with the supporting seat upper cover 22; then, after the side plates 41 and the baffle plates 42 of the box body 4 are transported to the installation platform 4000, the side plates 41 and the baffle plates 42 are connected with the rack 1, the dustproof sealing device 43 is assembled to form the box body 4, and then the steel plates forming the gear box 5 are transported to form the gear box 5; finally, all the components of the driving part 6 are transported to the mounting platform 4000 and connected; finally, the double-gear crusher 1000 is assembled on the mounting platform 4000, and the double-gear crusher 1000 is mounted.

After the feeding chute 2000 is connected to the discharging chute 3000, the connection between the dual-gear crusher 1000 and other equipment is completed. As can be seen, according to the double-geared roller crusher 1000 implemented by the technical solution of the present invention, because the technical solution of driving by a single motor and a reducer is adopted, the width of the driving portion 6 can be controlled within a certain smaller size range, and after the diameters of the driving toothed roller 31 and the driven toothed roller 32 of the pair roller assembly 3 are controlled within a smaller size, the handling capacity of the double-geared roller crusher 1000 can be satisfied by designing the length of the toothed roller segments; therefore, the double-geared roller crusher 1000 can be designed to have a narrow and long shape, and is suitable for a narrow and long working space; because the modularized design is adopted, the movable support can be decomposed into a plurality of small components, and is convenient for carrying, field assembly, maintenance and repair of the components.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
