Vibrating screening equipment which has intermittent feeding function and is used for granulate materials

Abstract

The invention provides vibrating screening equipment which has an intermittent feeding function and is used for granulate materials so as to achieve the purpose. The vibrating screening equipment comprises a machine shell. A ring-shaped supporting plate is arranged in the machine shell. A screen is fixedly connected to the bottom of the ring-shaped supporting plate. The screen is connected with the inner bottom of the machine shell through a screen vibrating device. A material disturbance device is arranged on the upper side of the screen and comprises a first rotating shaft. The top end of the first rotating shaft penetrates the machine shell and extends upwards. The top end of the first rotating shaft is fixedly connected with an output shaft of a first motor. The equipment has the following beneficial effects that the first rotating shaft drives a disturbance protrusion to rotate through a matching rod, the disturbance protrusion disturbs the materials on the screen so as to ensurenormal processing of the screening work, and the problem about material piling is effectively solved; and by means of a first spring arranged on the portion, the matching rod can move up and down in the rotating process, and thus the matching rod can adapt to the screen moving up and down.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a vibrating screening device for granular materials with intermittent feeding function. Background technique [0002] Screening is the process of using a sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be regarded as composed of two stages: material stratification and fine particle sieving; material stratification is the condition for separation, and fine particle sieving is the purpose of separation. [0003] In the industrial production process, granular materials often exist, and granular materials need to be screened to obtain the required particle size; those that do not meet the particle size requirements need to be pulverized again....

AI Technical Summary

Problems solved by technology

There are a lot of screening equipment at present, and the vibrating screen is generally used to screen materials. The vibrating screen is vibrated by a vibrating motor, but its vibration amplitude is small, and it is difficult to achieve a good screening effect; There is a disturbance device. When the granular materials are gathered together, it is difficult to achieve a better screening effect. In addition, the feeding of granular materials is also very important. When a large amount of materials are added at one time, the materials will accumulate on the screen and the screening effect will be poor. Poor; leads to waste of resources when adding less
