Description

A waste plastic washing machine

technical field

The utility model relates to the technical field of cleaning and recycling waste plastics, in particular to a waste plastic cleaning machine.

Background technique

At present, after waste plastics such as plastic bottles, plastic sheets, and plastic films are processed by a thermal cleaning machine, it is generally necessary to further remove the oil stains and glue remaining on the waste plastics through a waste plastic cleaning machine. The structure of the waste plastic washing machine currently used is: including a shell, the inside of which is divided into a relatively independent upper chamber and a lower chamber by a screen. There is a discharge port at the bottom, and a main shaft driven by a motor is movably supported between the front and rear ends of the upper chamber. A disconnecting screw is arranged on the shaft of the main shaft along the axial direction, and a row of The outlet is directed downwards to the cleaning pipe of the screen, and a drain is arranged at the bottom of the lower chamber. When in use, first start the motor to drive the main shaft to rotate at high speed, and open the cleaning pipe, so that the cleaning pipe can wash the screen, and then put the waste plastic into the upper chamber of the shell from the feeding port, and the waste plastic that enters the upper chamber Under the conveying of the main shaft, it will spiral forward to the discharge port. When the waste plastics travel to the discharge port, there will be mutual friction between the waste plastics and the waste plastics, and between the waste plastics and the high-speed rotating main shaft, thus Remove the residual oil and viscose on the waste plastic, and the removed oil and viscose will enter the lower chamber through the screen, and when the waste plastic travels to the discharge port, the water flow from the cleaning pipe will continue Flush the screen, flush the oil and viscose on the screen into the lower chamber, and the oil and viscose that enter the lower chamber are discharged from the drain. The disadvantages of the above-mentioned waste plastic cleaning machine are: the cleaning effect on waste plastics is poor, and the cleaning effect on the screen is poor, which leads to the fact that the screen is easily cleaned by extremely fine waste plastics and debris from waste plastics during the cleaning process of waste plastics. Oil and viscose clogging, once the screen is clogged, the waste plastics entering the equipment will not be cleaned, and the machine must be shut down to manually remove the extremely fine waste plastics, oil and viscose on the screen, which greatly affects the operation of the entire production line. Normal production greatly affects the production efficiency of the entire production line.

Detailed ways

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

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of waste plastic cleaning machine described includes: a frame 1, an organic barrel 2 is arranged on the frame 1, and a feeding port is arranged on the top of the front end of the barrel 2 3. A discharge port 4 is provided at the bottom of the rear end of the barrel 2. A spindle 5 driven by a driving mechanism and hollow inside is movably supported between the front and rear ends of the barrel 2. On one side of the spindle 5, the shaft end It is provided with a rotary joint 6 that communicates with the inside and is located outside the machine barrel 2. On the shaft body of the main shaft 5, a number of water spray holes 7 are arranged in the circumferential direction, and a number of shifting plates 8 are spirally arranged in the axial direction. The outside of the main shaft 5 between the mouth 3 and the discharge port 4 is surrounded by a cylindrical screen 9 installed on the inner wall of the barrel 2. The cylindrical screen 9 separates the inside of the barrel 2 from the feed port 3 and the discharge port. The inner chamber 10 that the mouth 4 communicates with, and the outer ring chamber 11 that communicates with the inner chamber 10 only through the cylindrical screen 9 mesh, is provided with on the side wall of the machine barrel 2 at the bottom of the outer ring chamber 11 The water outlet, the water outlet communicates with the water receiving box 12 arranged on the frame 1 below the machine barrel 2, and a water outlet 13 is provided on the lower side wall of the water receiving box 12; in the present embodiment, the water outlet of the water receiving box 12 13 is set on the side plate 121 of the water receiving box, the bottom plate 122 of the water receiving box 12 is gradually inclined downwards to the side of the water outlet, and the bottom plate 122 is just tangent to the water outlet 13, so that the machine barrel 2 can be discharged into the water receiving box The dirt of 10 is more smoothly discharged from the drain; A drive pulley 16 is installed on the output shaft of 15, and a belt 17 is wound between the drive pulley 16 and the passive pulley 15.
