Description

Technical Field

[0001] The invention relates to the technical field of PET bottle recycling equipment, in particular to a high-speed double-turbulence hot washing separation device. Background Art

[0002] In the PET bottle recycling industry, the PET bottles need to be crushed, cleaned, dehydrated, dried and other processes in sequence. Since the discarded PET bottles themselves have a certain degree of turbidity and will be subject to a certain degree of secondary pollution during storage and transportation, in order to achieve the recycling and reuse of PET bottles, the PET bottles need to be cleaned. At present, the device for cleaning the crushed PET bottle flakes includes: a base frame, a cylindrical tank body is arranged on the base frame, a stirring device is installed at the center of the cylindrical tank body, the stirring device is driven to rotate by a driving device, a discharge port is arranged on one side of the bottom of the cylindrical tank body, the discharge port is used in conjunction with the stirring device, and a discharge screw conveyor is installed at the discharge port. When the above-mentioned cleaning device is working, after the crushed PET bottle flakes enter the cylindrical tank body, due to the physical characteristics of the PET bottle flakes, their density is greater than the cleaning solution. Under the action of the stirring device, the PET bottle flakes gradually rotate and sink, fall into the bottom of the cylindrical tank body, enter the discharge screw conveyor through the discharge port, and are transported out of the cleaning device under the action of the discharge screw conveyor. When the cleaning device of this structure cleans PET bottle flakes, the impurities such as mud, gravel and the like with a density greater than that of the cleaning solution mixed in the PET bottle flakes fall into the bottom of the cylindrical tank body together with the PET bottle flakes. As the working time increases, the impurities in the cylindrical tank body gradually accumulate and are transported out of the cleaning device together with the PET bottle flakes, failing to achieve an effective cleaning effect. Moreover, the PET bottle flakes fall into the bottom of the cylindrical tank body and are deposited in a relatively short time, and the cleaning solution does not fully clean the PET bottle flakes. Therefore, those skilled in the art provide a high-speed dual-turbulence hot washing separation device to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0011] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. 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 creative labor.

[0012] See Figure 1 —— Figure 2 As shown, this specific embodiment adopts the following technical scheme: it comprises a base frame 1, a cleaning tank body 2, a steam heating coil 3, a feed port 4, a high-speed turbulence device 6 and a cache separation device 17; the cleaning tank body 2 is installed on the base frame 1, the steam heating coil 3 is installed in the cleaning tank body 2, the top of the cleaning tank body 2 is provided with a feed port 4, an inspection hole 5 and two groups of high-speed turbulence devices 6, the high-speed turbulence device 6 comprises a rotating base 7, a rotating shaft 8 and turbulence blades 9, the rotating shaft 8 is inserted in the cleaning tank body 2, and the rotating shaft 8 The upper part is installed in the rotating base 7 through a bearing, the rotating shaft 8 is connected to the driving motor through a pulley, and turbulent blades 9 are evenly installed on the rotating shaft 8 at a certain angle. The rotating shafts 8 on the two groups of high-speed turbulent devices 6 rotate at high speed driven by the driving motor. Under the action of the turbulent blades 9, two groups of turbulence are generated in the cleaning tank body 2, so that the PET bottle pieces rotate at high speed with the turbulence and are fully in contact with the cleaning solution. Under the action of high-speed rotation, the suspension time of the PET bottle pieces in the cleaning tank body 2 is increased, thereby achieving the best cleaning effect.

[0013] A discharge port 14 is provided at the bottom of the cleaning tank body 2, and a connecting pipe 16 is connected to the discharge port 14, and a pneumatic gate valve 15 is installed on the connecting pipe 16; the cache separation device 17 comprises a separation tank body 18, a conveying screw 19, a separation screen 20 and a cache solution tank 21, the bottom of the connecting pipe 16 is connected to the separation tank body 18, and a conveying screw 19 is installed at the bottom of the separation tank body 18, and the conveying screw 19 is driven by a motor. A separation screen 20 is provided below the conveying screw 19, and a cache solution tank 21 is provided below the separation screen 20. A drainage pump 22 is installed on one side of the cache solution tank 21, and a cleaning and maintenance port 23 is installed on the other side.

[0014] An observation window 10 is provided on one side of the cleaning tank body 2 , and a pneumatic angle seat valve 11 and a steam trap 12 are installed on the other side. The pneumatic angle seat valve 11 is installed and connected to the steam heating coil 3 , and a temperature sensor 13 is installed on the side wall of the cleaning tank body 2 .

[0015] The working principle of the present invention is as follows: the crushed PET bottle flakes enter the cleaning tank body 2 from the feed port 4. Since the density of the PET bottle flakes is greater than that of the cleaning solution, the PET bottle flakes entering the cleaning tank body 2 fall to the bottom of the cleaning tank body 2. During the falling process, the two sets of high-speed turbulence devices 6 clean the crushed PET bottle flakes. When the PET bottle flakes reach the set cleaning time, the pneumatic gate valve 15 is opened, and the cleaning solution and the PET bottle flakes in the cleaning tank body 2 pass through the discharge port 14, the pneumatic gate valve 15 and the connecting pipe 16 at the bottom of the cleaning tank body 2 in turn, and enter the separation tank body 18 of the buffer separation device 17. Under the action of the separation partition 20, the PET bottle flakes remain in the separation tank body 18 and are transported to the next equipment under the action of the conveying screw 19 at the bottom of the separation tank body 18. The cleaning solution containing impurities such as mud, sand, and gravel enters the buffer solution box 21 below the separation partition 20, and is transported to the cleaning solution filtering equipment under the action of the drainage pump 22 on the left side of the buffer solution box 21.
