Embodiment Construction

[0025] As shown in Figure 15, this system is by pulverizer 26, raw material bin 4 ', screening dedusting machine 27 and powder bin 5 '.

[0026] Such as figure 1 , figure 2 , image 3 , Figure 5 As shown, the pulverizer includes a workbench 1, a feed hopper 2, a belt pulley 5, a transmission gear 6 and a control box 7. The pulverizer is provided with a feed hopper 2 in turn, and a crushing mechanism 3 is provided under the feed hopper. A grinding mechanism 4 is arranged under the mechanism; a belt cover and a gear cover are respectively arranged on the belt disc 5 and the transmission gear 6 .

[0027] Such as Figure 6 , The pulverizing mechanism is made up of the active pulverizing shaft 8 distributed in parallel, the driven pulverizing shaft 9, and the pulverizing knives 14 arranged on the shaft, and the pulverizing knives are arranged on the shaft according to a 45° helical distribution. Such as Figure 4 , Figure 7 , Figure 8 , the grinding mechanism is provid...

Abstract

The recovering system of expandable polystyrene consists of crusher and sieving and dedusting machine. The crusher has successively set worktable, feeding bin, crushing mechanism and grinding mechanism. The sieving and dedusting machine has material bin connected to the feeder, screw feeding shaft connected to the sieving shaft of the sieving mechanism, and stirring rod fixed onto the sieving shaft. The present invention has two-stage crushing mechanism with good crushing effect and adjustable granularity, and good sieving effect, and is safe, reliable and homogeneous in material feeding.

Description

Technical field: [0001] The invention relates to a recovery device for expandable polystyrene. Background technique: [0002] Because expandable polystyrene has good heat insulation, sound insulation, shockproof and other properties, its application is becoming more and more extensive. However, the recycling of expandable polystyrene products has been perplexing the development of the foam plastic industry. Under normal circumstances, the recycling of expandable polystyrene products mainly adopts the following methods: regeneration granulation, making lightweight insulation building materials, incineration to convert energy, etc. [0003] The treatment method of regeneration granulation is to obtain transparent styrene raw materials through processes such as crushing-melting-condensation-kneading-extrusion-cooling-granulation of the foamed expandable polystyrene waste. Not only the processing process is complicated, but also the cost is higher. The market has been looking...
