Description

Technical Field

[0001] This utility model belongs to the field of PVC plastic crushing technology, and in particular, it is a plastic scrap crushing device. Background Technology

[0002] The PVC plastic crushing process begins by crushing the recycled raw materials in a fully enclosed crushing workshop. After crushing, the PVC in the raw materials is broken down into PVC particles with a particle size of approximately 1mm, while the cotton is crushed into lint. During the crushing process, a dust collection hood is installed above the crusher. The cotton lint particles are collected by the dust collection hood and then enter a bag filter through pipes for treatment before being discharged through the DA001 exhaust pipe.

[0003] Currently, after PVC plastic is crushed, the cotton shreds are collected through a dust collection hood and a bag filter. However, some cotton shreds accumulate under the PVC plastic particles and cannot be collected, affecting the quality of the finished product.

[0004] Therefore, in view of this situation, there is an urgent need to design and produce a plastic scrap crushing device to meet the needs of practical use. Utility Model Content

[0005] The purpose of this invention is to provide a plastic scrap crushing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic scrap crushing device, comprising an outer shell, a rotating shaft rotatably connected inside the outer shell, a rotating box fixedly connected to the upper side of the rotating shaft, a filter plate installed on the side of the rotating box, a shielding cloth connected to the outer shell and connected to the upper side of the rotating box, a conveying device fixedly connected inside the outer shell, a push plate fixedly connected to the side of the conveying device, a support plate fixedly connected to the inner side of the outer shell, a return spring welded to the rotating box and welded to the upper side of the support plate, and a cover plate screwed to the upper side of the outer shell.

[0007] Preferably, a crushing inlet for crushing plastic scraps is installed on the upper side of the cover plate, and a conveying pipe is connected to the upper side of the crushing inlet.

[0008] Preferably, a first gas collecting hood is installed on the upper side of the cover plate, and the air inlet end of the first gas collecting hood is connected to a first gas supply pipe.

[0009] Preferably, a bag filter is connected to the end of the first gas supply pipe away from the first gas collecting hood, and a second gas collecting hood is installed on the lower side of the cover plate.

[0010] Preferably, the upper side of the second gas collecting hood is connected to a second air supply pipe that is connected to the bag filter, and an air jet pipe is installed inside the outer shell.

[0011] Preferably, a third gas supply pipe is connected to the side of the jet pipe, and a gas tank is connected to the end of the third gas supply pipe away from the jet pipe.

[0012] Preferably, a storage box is installed inside the outer casing.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The plastic scrap crushing device moves the push plate through the conveying device, which in turn drives the rotating box to rotate. The conveying device also drives the push plate to move in a cycle, which in turn drives the rotating box to rotate in a cycle. This causes the cotton dust and PVC plastic particles to move up and down, making it easier to collect the cotton dust on the lower side. At the same time, when the PVC plastic particles are filtered through the filter plate, the cotton dust will also be exposed and then collected through the first and second gas collection hoods.

[0015] At the same time, the gas tank and the third air supply pipe blow the filtered cotton dust to the second gas collection hood, where the cotton dust is collected at the bag filter for further collection. Attached Figure Description
