Description

Multi-stage dehydration device for recycled polypropylene fiber production line

technical field

The utility model relates to the field of recycled polypropylene production equipment, in particular to a multi-stage dehydration device for a recycled polypropylene production line.

Background technique

With the development of recycling technology, waste plastics can be recycled for the re-production of polypropylene. At present, the waste plastics required for the production of recycled polypropylene need to be cut and cleaned in order to meet the technical requirements of production, but after cleaning, the waste plastics need to be dehydrated and dried.

The current patent publication number 201308864Y provides a continuous centrifugal dehydration device for dehydrating plastic sheets, which includes an outer cylinder, a centrifugal drum disposed in the outer cylinder, and a transmission motor that drives the centrifugal drum to rotate. The top of the body is provided with a feed inlet, and the bottom is provided with a water outlet. The side wall of the centrifugal drum is provided with mesh holes, the inner wall is provided with dehydration blades, and the top of the side wall is provided with a discharge port.

The continuous centrifugal dehydration device provided above has a relatively complicated structure. The plastic sheet is driven upward to the discharge port by the dehydration blade, and the whole device is vertically arranged, which makes the dehydration efficiency of the plastic sheet low and uneven. Or, the number of dehydration device is only one, so it cannot guarantee that the waste plastics after cutting can reach the drying degree required by production, if drying is required, it will also increase the difficulty of drying.

Utility model content

The utility model provides a multi-stage dehydration device for a recycled polypropylene fiber production line. The main purpose of the utility model is to overcome the problems of low dehydration efficiency and uneven dehydration of the existing dehydration device.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

The multi-stage dehydration device of the recycled polypropylene production line includes a plurality of dehydration bodies arranged in sequence. Each dehydration body includes a shell, a hollow drum inside the shell, and a transmission motor that drives the drum to rotate. The two shells Both ends of the drum are provided with a feed port and a discharge port. Both ends of the drum are provided with openings. The feed port and the discharge port are respectively connected with the openings at both ends of the drum. There are a plurality of dehydration holes, and a communication pipe is connected between the discharge port and the feed port of two adjacent dehydration bodies, and a fan for absorbing materials is arranged in the communication pipe.

The dehydration device also includes a drying mechanism, a material pipeline is connected between the drying mechanism and the discharge port of the dehydration body at the end of the arrangement, and a fan for absorbing materials is arranged in the material pipeline.

A water outlet is provided at the bottom of the housing, and a support frame is provided at the bottom.

The number of the dehydrating bodies is two.

The drum is horizontally installed in the casing.

From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: the waste plastics after cleaning can enter the drum from the feed port, and the drum can rotate at a high speed driven by the drive motor. In this way, the water is thrown out from the dehydration holes, and the waste plastics are transported between the adjacent two dehydration bodies through connecting pipes and fans. After dehydration by multiple dehydration bodies, the waste plastics are drier, and the drying time can be reduced during drying. Dry difficulty, shorten drying time. In addition, the drum is horizontally installed in the casing, which can make the dehydration of waste plastics more uniform. This dehydration method has higher dehydration efficiency than the existing dehydration method.
