[0002] Due to the soaring use of plastics, the domestic and foreign recycling infrastructure cannot keep up, resulting in serious ocean pollution of waste plastics. With the increasing emphasis on environmental protection, the recycling of waste plastics has risen to a national strategic issue. The rationality and reliability of the structure of the cleaning pipe greatly determine the cleaning effect of the recycling and cleaning of waste plastics. The existing cleaning pipe structure on the market at home and abroad is mostly in the form of a single short pipe, similar to an ordinary tubular screw conveyor, and a stirring and conveying rod (the existing stirring and conveying rod generally includes a main shaft and stirring blades) is arranged in the pipe. Due to the short effective stroke of the existing cleaning pipe, the stirring blades must be driven at high speed to apply corresponding blade striking force to the material to achieve an ideal cleaning effect. The disadvantage of the existing cleaning pipe structure is that high-speed cleaning will cause damage to the material due to the high rotation speed and large striking force on the material, and in severe cases, the material will be ground into powder.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] This invention provides a multi-pipe combined plastic cleaning channel and a waste plastic cleaning device using this plastic cleaning channel. Specifically, the material cleaned in this embodiment is waste plastic sheets, and the cleaning media used are sand and water.
[0027] refer to Figures 1-5 The plastic cleaning channel in this embodiment includes multiple cleaning pipes 1 connected in sequence. Each of the multiple cleaning pipes 1 has a built-in stirring and conveying rod 11. For two adjacent cleaning pipes 1, the cleaning pipe 1 in front can stir and convey the material to the cleaning pipe 1 in the back through the stirring and conveying rod 11.
[0028] Specifically, the first cleaning pipe 1 among the multiple cleaning pipes 1 is provided with an inlet 2 for the plastic cleaning channel, and each of the remaining cleaning pipes 1 is provided with an input port 12 for communicating with the preceding cleaning pipe 1. The last cleaning pipe 1 among the multiple cleaning pipes 1 is provided with an outlet 3 for the plastic cleaning channel, and each of the remaining cleaning pipes 1 is provided with an output port 13 for communicating with the following cleaning pipe 1.
[0029] Specifically, a connecting pipe 4 is connected between two adjacent cleaning pipes 1, one end of the connecting pipe 4 is connected with the output port 13 of the cleaning pipe 1 in the front position, and the other end is connected with the input port 12 of the cleaning pipe 1 in the rear position. Specifically, the connecting pipe 4 is a pipe flange.
[0030] Specifically, the output port 13 connected by the same connecting pipe 4 is higher than the input port 12 connected by the same connecting pipe 4, that is, for two adjacent cleaning pipes, the height of the output port 13 of the front pipe is higher than the height of the input port 12 of the rear pipe, so that the material can smoothly enter the rear pipe from the front pipe.
[0031] Specifically, two adjacent cleaning pipes 1 and the connecting pipe 4 therebetween jointly form a bent pipe, so that the plastic cleaning channel forms a circuitous channel structure, which can increase the effective cleaning stroke while reducing the space occupation.
[0032] Specifically, in order to make the output port 13 connected by the same connecting pipe 4 higher than the input port 12 connected by the same connecting pipe 4, the cleaning pipe 1 of the embodiment can be arranged as follows: the plurality of cleaning pipes 1 are arranged in the horizontal direction, and the output port 13 and the input port 12 are arranged in the horizontal direction of the cleaning pipe 1, the plurality of cleaning pipes 1 all form an upward angle relative to the horizontal plane, and the upward directions of the two adjacent cleaning pipes 1 are opposite.
[0033] Specifically, the bottom of each cleaning pipe 1 is provided with a first supporting leg 14 and a second supporting leg 15, which are detachably connected with the cleaning pipe 1 to facilitate the maintenance of the cleaning pipe 1, and the height of the first supporting leg 14 is lower than the height of the second supporting leg 15, so that the cleaning pipe 1 forms an upward angle, specifically, the size of the upward angle is 4 degrees.
[0034] Specifically, the stirring and conveying rod 11 includes a main shaft 111, the main shaft 111 alternately has a spiral blade 112 and a stirring blade 113, and the end of the stirring and conveying rod 11 is provided with a reverse spiral piece 114, and a push plate 115 is arranged between the reverse spiral piece 114 and the spiral blade 112 closest to the reverse spiral piece 114.
[0035] The plastic cleaning channel of the multi-pipe combination and the waste plastic cleaning device using the plastic cleaning channel provided by the embodiment comprise a plurality of cleaning pipes 1 connected in sequence, each of the cleaning pipes 1 is internally provided with a stirring and conveying rod 11, and for two adjacent cleaning pipes 1, the cleaning pipe 1 in the front position can stir and convey the material to the cleaning pipe 1 in the rear position through the stirring and conveying rod 11, so that the material can be sequentially cleaned by the cleaning pipes 1. The embodiment increases the effective cleaning stroke through the structure of the multi-pipe combination, so that the material and the cleaning medium can be fully stirred and cleaned by using the low-speed operation mode, that is, through the combination of the long stroke and the low speed, the disadvantages of insufficient stirring and cleaning and damage to the material can be effectively avoided.
[0036] To realize the combination of the long stroke and the low speed, it is necessary to ensure that the material and the cleaning medium can smoothly pass through each cleaning pipe 1 of the plastic cleaning channel, and two points must be ensured: first, the material and the cleaning medium can be stirred and transported to the position where the output port 13 or the discharge port 3 is located in the same cleaning pipe 1, that is, the effective stirring and transportation in the pipe are ensured; second, the material and the cleaning medium can be smoothly transferred from the front pipe to the rear pipe, that is, the effective transportation between the pipes is ensured.
[0037] Since the stirring rod of the prior art is mainly suitable for high-speed centrifugal cleaning, it has the problem of low conveying efficiency, and when it operates at a low speed, it often cannot effectively convey the material, especially for long-stroke material conveying, and the material at the tail end of the pipe is prone to blockage. Since the stirring and conveying rod 11 of the embodiment is provided with alternating helical blades 112 and stirring blades 113 on the main shaft 111, the effective stirring and cleaning and the effective transportation of the material in the pipe can be ensured, that is, the effective stirring and transportation in the pipe are realized; and the end of the stirring and conveying rod 11 is provided with a reverse helical blade 114 to prevent the material from blocking, and a push plate 115 is arranged between the reverse helical blade 114 and the most adjacent helical blade 112, which can conveniently and smoothly transfer the material and the cleaning medium to the next cleaning pipe 1, that is, the effective transportation between the pipes is realized.
[0038] The working process of the embodiment is as follows: the material and the cleaning medium are sent to the inlet port 2 by the conveyor, the motor of the cleaning pipe 1 drives the stirring and conveying rod 11 to rotate at a low speed, the material is conveyed forward while being fully stirred with the cleaning medium, a friction cleaning effect is achieved, the pipe flange used for connecting the pipes can make the material smoothly slide from the front pipe to the rear pipe, and finally the material is output from the discharge port 3 to the next process.
[0039] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the protection scope of the present application.
