Description

Styrofoam pulverizer

technical field

The utility model relates to a pulverizer for pulverizing waste foam plastics.

Background technique

In the prior art, industrialized recycling and reuse of waste foam plastics requires primary crushing and processing. For a long time, the crushing processing equipment used by each primary crushing processing unit only has the crushing function. Due to the dirty and bad environment of the primary processing units, especially the waste recycling points, the processing sites are polluted, there are many types of waste materials, disorderly, and some waste foam blocks are accompanied by other types of sundries and other factors, resulting in the crushed The material contains a certain amount of impurities such as sediment, rotten cloth strips, cigarette butts, waste nail heads, etc., which seriously affects the quality of the crushed material and reduces the level of reuse of the material.

At present, a foam plastic pulverizer is widely used in the industry, which consists of four parts: feeding hopper, crushing mechanism, collecting hopper and material output pipe. In the feeding hopper, the foamed plastic block is soon crushed by the crushing mechanism set under the feeding hopper, and then the crushed material enters the material output pipe through the collecting hopper set at the lower part of the crushing mechanism, and is discharged from the material output pipe to the outside of the machine body . Although the crushing efficiency of this model is high and the crushing effect is good, because it only has the crushing function like other types of foam plastic crushers, impurities in the foam plastic materials after crushing by the crusher with this structure still exist. It makes the majority of primary crushing and processing units very helpless.

Contents of the invention

The purpose of this utility model is to provide an improved foam plastic pulverizer, which can not only pulverize foam plastic blocks with high efficiency and high quality, but also remove impurities in the pulverized materials, so that the pulverizer can output The crushed material is clean and less impurity.

The purpose of this utility model is achieved in this way: with the above-mentioned foamed plastic pulverizer consisting of the feeding hopper, the pulverizing mechanism, the collecting hopper and the material output pipe as the base body, the pulverized material is discharged downstream of the pulverizing mechanism. A set of impurity removal and cleaning device that can remove impurities in the crushed material is installed on the body, so that the crushed material passes through the set impurity removal and cleaning device during the discharge process and is cleaned by the impurity removal, so that the pulverizer can discharge clean impurities with less impurities. Shred material.

The above impurity removal and cleaning device may be one of the following three structures, or may be a structure composed of two or three structures. The impurity removal and cleaning devices of these three structures are:

A miscellaneous plate is installed horizontally on the lower lip of the outlet of the collecting hopper, and a miscellaneous outlet is made on the bottom panel of the collecting hopper on the upstream side of the miscellaneous plate. When the crushed material passes through the outlet of the collecting hopper, the impurities shaken off on the bottom panel of the collecting hopper will be discharged from the outlet, and the impurities mixed in the material will be intercepted by the trash plate and discharged from the outlet .

Install a miscellaneous plate horizontally at the bottom of the end of the material output pipe, and make a miscellaneous outlet at the bottom of the material output pipe on the upstream side of the miscellaneous plate. When the crushed material passes through the material output pipe, the mixed in the material Impurities will be intercepted by the miscellaneous plate and discharged from the miscellaneous outlet.

Make a screen structure in a certain area on the material output pipe, and close the area formed by the screen structure from the outside of the material output pipe by the opening of a funnel-shaped shell, and make the rear end of the funnel-shaped shell contact with a negative pressure The source is connected. This structure can suck out the impurities in the pulverized material passing through the material output pipe through the suction of the negative pressure source.

Since the utility model only needs to make simple openings on some parts of the existing mature and shaped foam plastics, and does not change the specific structure of each main function component and the configuration structure between each main function component, the utility model The new structure is simple, and the original crushing performance is not affected. At the same time, because the impurities in the crushed materials are removed, the reuse level of the crushed materials is improved, and the economic benefits of the processing unit are increased.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
