Vibration screening mechanism

Technical Field

The invention relates to a vibration screening mechanism.

Background

In the traditional cement manufacturing process, the screening of cement raw materials plays a critical role in the continuous production of cement, at present, the cement screening is mainly realized by means of a vibration screening mechanism, a sieve plate in the existing vibration screening mechanism is made of steel, the size is large, the weight is heavy, the vibration amplitude of the sieve plate under the action of a vibration motor is very small, the screening effect is poor, if a high-power vibration motor is selected, the energy consumption is increased, and the sieve plate and a foundation are damaged after long-time operation; meanwhile, the grids of the sieve plate are often blocked, frequent shutdown and manual removal are needed, and therefore production efficiency is low and further improvement is needed.

Disclosure of Invention

In view of the current situation of the prior art, the technical problem to be solved by the invention is to provide a vibrating screening mechanism which can greatly improve the screening effect without selecting a high-power vibrating motor, thereby avoiding the increase of energy consumption, avoiding the damage to a screen plate and a foundation and simultaneously improving the production efficiency.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a vibration screening mechanism which characterized in that: the hopper is arranged below the vibration component, the sliding plate is obliquely arranged below the right end of the vibration component, and the vibration component comprises a plurality of vibration units; a plurality of the vibration unit is arranged from the past backward in proper order, the vibration unit includes sieve, stand, vibrating motor, spring and bracket, the sieve slope sets up, the left end downside at the sieve is fixed to the bracket, vibrating motor fixes in the bracket, the below of bracket with the right-hand member below of sieve all is equipped with the stand of a plurality of vertical distributions, left every the downside at the bracket, every are all fixed through a spring in the upper end of stand the upper end of right side the right-hand member downside at the sieve is also all fixed through a spring in the upper end of stand.

Preferably, the left end of the sliding plate is matched with the right end of the sieve plate in the plurality of vibration units.

Preferably, the inclination of the screen deck is matched with the inclination of the slide plate.

Compared with the prior art, the invention has the advantages that: according to the invention, the materials are uniformly divided into a plurality of material piles by virtue of the plurality of vibration units and are screened independently, and the vibration amplitude of the sieve plate can be greatly increased without selecting a high-power vibration motor, so that the screening effect is greatly improved, the increase of energy consumption is avoided, and the sieve plate and the foundation are prevented from being damaged; meanwhile, the inclined arrangement of the sieve plate and the sliding plate better solves the problem of frequent material blockage of sieve plate grids, thereby greatly reducing the frequency of shutdown and manual removal and improving the production efficiency.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in fig. 1 to 3, a vibrating screening mechanism comprises a vibrating assembly, a hopper 4 and a sliding plate 5, wherein the hopper 4 is arranged below the vibrating assembly, the sliding plate 5 is obliquely arranged below the right end of the vibrating assembly, and the vibrating assembly comprises a plurality of vibrating units; a plurality of vibrating unit from the past backward arrange in proper order, vibrating unit includes sieve 6, stand 3, vibrating motor 1, spring 2 and bracket 7, the slope setting of sieve 6, the slope of sieve 6 and the slope of slide 5 are mutually supported, bracket 7 fixes the left end downside at sieve 6, vibrating motor 1 fixes in bracket 7, the below of bracket 7 and the right-hand member below of sieve 6 all are equipped with the stand 3 of a plurality of vertical distributions, the downside at bracket 7 is all fixed through a spring 2 to the upper end of every left stand 3, the right-hand member downside at sieve 6 is also all fixed through a spring 2 to the upper end of every stand 3 on right side, the left end of slide 5 and the right-hand member of the sieve 6 in a plurality of vibrating unit all mutually support.

When in use: the grab bucket grabs the materials and moves to the upper part of the vibration assembly and releases the materials, the materials fall onto the sieve plates 6 in the plurality of vibration units immediately, qualified materials pass through the sieve plates 6 and are concentrated in the hopper 4, unqualified materials slide onto the sliding plates 5 along the sieve plates 6 and slide into the storage bin through the sliding plates 5, and therefore the materials are screened.

A plurality of sieve 6 divide equally into a plurality of material piles with the material for the weight that every sieve 6 bore reduces greatly, and the vibration range greatly increased under the effect of a vibrating motor 1 that corresponds of every sieve 6, thereby has promoted the screening effect by a wide margin.

According to the invention, the materials are uniformly divided into a plurality of material piles by virtue of the plurality of vibration units and are screened independently, and the vibration amplitude of the sieve plate 6 can be greatly increased without selecting the high-power vibration motor 1, so that the screening effect is greatly improved, the increase of energy consumption is avoided, and the sieve plate and the foundation are prevented from being damaged; meanwhile, the inclined arrangement of the sieve plate 6 and the sliding plate 5 well solves the problem of frequent material blockage of sieve plate grids, so that the frequency of shutdown and manual removal is greatly reduced, and the production efficiency is improved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
