Example Embodiment

[0017] The present invention will be further described in detail below through specific embodiments.

[0018] The high temperature mentioned in this embodiment does not mean that the high temperature is higher than a specific temperature value. The high temperature raised in the present invention means that the temperature range that can change the color of the PVC or PC bottle is called high temperature.

[0019] Such as figure 1 , 2 As shown, a PET bottle pre-cleaning separator includes a frame 1, a roller 2, a roller drive device 6. The roller 2 is rotatably mounted on the frame 1, and the roller drive device 6 is mounted on the frame 1 and The drive connection with the roller 2 can drive the roller 2 to rotate. The frame 1 includes at least three fixed supports, which are evenly distributed along the length of the roller 2, and each fixed support is installed below the roller 2 At least two support rollers 10, at least two limit rollers 11 are installed on the fixed support abo...

Abstract

The invention discloses a pre-cleaning separator for a PET (Polyethylene Terephthalate) bottle. The pre-cleaning separator comprises a frame, a rotary drum and a drum drive device, wherein the drum is rotatably arranged on the frame and is driven to rotate by the drum drive device, a feed inlet is formed in one end of the rotary drum, a discharge port is formed in the other end of the rotary drum, an upstream section, which is close to the feed inlet, of the body of the rotary drum is arranged to a circumferential closed section, a separation section with sieve holes is arranged on a downstream section, the body, which is close to the discharge hole, of the body of the rotary drum, spiral material push blades are arranged on the inner wall of the rotary drum, and rinsing baths, which are extended in a spiral manner, are further fixed on the inner wall of the upstream section of the rotary drum; a sundries discharge bucket is arranged on a screen drum below the separation section, and a high-temperature water injection pipe is further arranged on the upstream section of the rotary drum. According to the separator, before separation, washing through the rinsing bath is performed in advance, and then impurities are separated, so that the PET bottle is cleaner after separation, clean bottle flakes are provided for subsequent crushing, damage to a crushing knife due to excessive impurities can be avoided, and the service life of a crushing machine is prolonged.

Description

technical field [0001] The invention relates to a separator for separating PVC and PC from PET bottles, in particular to a PET bottle pre-cleaning separator. Background technique [0002] PVC bottles or PC bottles are often mixed in the recycling of PET bottles. Since PVC and PC have different high-temperature discoloration properties than PET bottles, the current separator is just using this characteristic for separation. The separated PET bottles need to be crushed in the crusher. However, when separated in the separator, there are some other impurities that cannot be separated, such as soil and sand pasted on the PET bottle. Once these impurities enter the crusher directly It may cause damage to the crushing knife of the crusher and reduce the service life of the crusher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PET bottle pre-cleaning separator, which is washed in a high-temperature water washing ta...
