Description

Technical Field

[0001] The invention relates to the technical field of PET bottle cleaning and recycling equipment, in particular to a pneumatic vibration separation device. Background Art

[0002] In the PET bottle cleaning and recycling industry, PET bottles need to be crushed, cleaned, dried, and other processes in sequence. In order to obtain higher-quality PET chips, separation equipment is usually used to remove the labels and powder remaining in the PET bottle chips after drying. Currently, known separation equipment includes: a rack, a vertical box body installed above the rack, a feed port provided above the vertical box body, a suction fan installed on the left side of the feed port, a discharge port provided below the vertical box body, and several miscellaneous outlets provided below the feed port and on the left side of the vertical box body. A miscellaneous outlet pipe is installed at the miscellaneous outlet, and the miscellaneous outlet pipe is connected to the suction port of the suction fan. When the separation equipment is working, PET bottle chips containing labels and powder enter the vertical box body from the feed port. During the falling process, due to the action of the suction fan, the labels and powder are sucked out of the box body by the suction fan, and the PET bottle chips are discharged from the discharge port. To maximize the suction fan's functionality, the material entering the vertical box must be evenly distributed so the suction fan can fully affect the labels and powder. However, this separation device lacks this functionality. Furthermore, the vertical box is at a certain height, and the suction fan is located above it. This results in the suction fan's effectiveness gradually decreasing from top to bottom within the vertical box. Consequently, the suction fan cannot fully function throughout the vertical box, seriously affecting the final quality of the PET bottle flakes. Therefore, those skilled in the art have provided a pneumatic vibration separation device to address the issues raised in the aforementioned background art. Summary of the Invention

DETAILED DESCRIPTION

[0011] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0012] See Figure 1 —— Figure 3As shown, this specific embodiment adopts the following technical solution: it includes a base frame 1, the upper end of the base frame 1 is connected to a vibration trough body 4 through an elastic vibration support 3, a vibration motor 5 is installed on the outside of the vibration trough body 4, and a feed port 6 and a discharge port 8 are respectively provided at both ends of the vibration trough body 4, a rotary valve 7 is installed on the feed port 6, and a partition 9 is installed in the vibration trough body 4. The material enters the partition 9 in the vibration trough body 4 from the feed port 6, and is evenly distributed on the partition 9 under the action of the vibration motor 5 and moves to the discharge port 8. Two air troughs 10 are provided on the partition 9, and the bottom of the air trough 10 is respectively connected to an air guide cover 11, and the air outlet of the wind knife 12 faces the air guide cover 11, and the air inlet of the wind knife 12 is connected to the vortex air pump 2 on the base frame 1 through the air volume regulating valve 13. Through the pipeline connection, the airflow generated by the vortex air pump 2 enters the wind knife 12 through the pipeline, and is blown to the material passing through the wind trough 10 through the wind guide hood 11; the vibration trough body 4 is provided with an air collecting hood 14, and the air collecting hood 14 is located above the wind trough 10. The air collecting hood 14 is connected to the induced draft fan 15 through a pipeline, and the air outlet of the induced draft fan 15 is connected to the dust collector 16 through a pipeline. The bottom of the dust collector 16 is connected to a collecting hopper 17, and a material level meter 18 is installed on the side wall of the collecting hopper 17. A pneumatic plug valve 19 is installed at the bottom of the collecting hopper 17. A collection box 20 is provided under the collecting hopper 17. The blown-away labels and powders are collected in the collecting hopper 17 by the induced draft fan 15 and the dust collector 16 for collection, and finally fall into the collection box 20 for convenient transportation.

[0013] The elastic vibration support 3 includes a spring bracket 31 and a connecting piece 32. The two spring brackets 31 are fixed on the connecting piece 32 at an angle of 85°~95°. The upper spring bracket 31 is fixed to the vibration trough body 4, and the lower spring bracket 31 is fixed to the base frame 1. The elastic vibration support 3 is used for the elastic support connection between the base frame 1 and the vibration trough body 4 to protect the base frame 1 from being damaged by vibration.

[0014] The working principle of the present invention is as follows: the material is transported to the rotary valve 7 by the upper equipment, and falls into the feed port 6 of the vibrating trough 4 under the action of the rotary valve 7. Driven by the vibrating motor 5, the material is evenly distributed on the partition 9 and transported to the discharge port 8. When passing through the wind trough 10, the airflow generated by the vortex air pump 2 enters the wind knife 12 through the pipeline. By adjusting the air volume regulating valve 13, the airflow size is adjusted to be appropriate. Under the joint action of the wind trough 10, the air guide cover 11 and the wind knife 12, the labels and powder are blown away from the PET slices, and under the action of the induced draft fan 15, they enter the air collecting cap 14 and enter the dust collector 16 through the pipeline. After the dust collector 16 unloads the airflow, it falls into the collecting hopper 17. After working for a period of time, when the labels and powder in the collecting hopper 17 accumulate to the material level meter 18, the material level meter 18 outputs a signal to control the opening of the pneumatic plug-in valve 19, and the labels and powder in the collecting hopper 17 fall into the collecting box 20.
