Waste plastic recycling dewatering machine

Abstract

The invention discloses a waste plastic recycling dehydrater which comprises a base, a machine shell, a screen drum and a main shaft with mixing blades. The bottom of the machine shell is fixed on the base, the screen drum is fixed in the machine shell, and the main shaft is horizontally installed in the center of the screen drum and penetrates through the screen drum and the machine shell. The two ends of the main shaft are fixed on the base through bearing pedestals, sealing devices are arranged at the connecting positions of the two ends of the main shaft and the machine shell respectively, and the main shaft is driven by a main shaft rotation power device to rotate. One end of the machine shell is provided with a feed port communicated with the interior of the screen drum, the other end of the machine shell is provided with a discharge port communicated with the interior of the screen drum, and a water outlet is formed in the bottom of the machine shell. The dewatering machine is reasonable in stress, and the sealing effect between the main shaft and the machine shell is good. In comparison with an existing structure, the main shaft of the dewatering machine is higher in speed, so that the dewatering effect is better.

Description

technical field [0001] The invention relates to a dehydrator, in particular to a dehydrator used for recycling waste plastics. Background technique [0002] The current plastic dehydrator generally includes a base, a casing, a screen and a main shaft with stirring blades. The casing is fixed on the base, and the two ends of the main shaft are rotated and installed on the casing through bearing seats, and the screen is fixed in the casing. , the blades on the main shaft are within the range of the screen, one end of the casing is provided with a feed port and the other end is provided with a discharge port, the main shaft is driven to rotate by the main shaft rotating power device, and the broken plastic film enters the screen and is agitated by the blades And produce a certain centrifugal force dehydration. However, the current crusher has the following deficiencies: 1. Since the main shaft is directly installed on the casing through the rotation of the bearing seat, the se...

AI Technical Summary

Problems solved by technology

However, the current crusher has the following disadvantages: 1. Since the main shaft is directly installed on the casing through the rotation of the bearing seat, the sealing requirements between the main shaft and the casing are very high, and the main shaft rotates at a high speed, and the casing bears The force of the dehydrator is very large, the casing is easily deformed at the connection with the main shaft, and then the seal will fail to cause water leakage, and the transmission reliability of the bearing seat after the water leakage cannot be guaranteed. Therefore, the structure of the current dehydrator is unreasonable. , high failure rate

2. Since the casing has to bear the force generated by the rotation of the main shaft, the rotational speed of the main shaft should not be too high. In this way, the dehydration effect of the material is poor and the dehydration time is long

3. The crushed material may have certain residues and fragments. During the dehydration process, these residues and fragments may remain on the screen. However, the cleaning mechanism of the current dehydrator generally adopts the method of washing with water. This method is extra Passing clean water, which causes the dehydration time of the dehydrator to be longer
