Description

Technical Field

[0001] The invention relates to the technical field of cleaning and recycling equipment for plastic bottles, and in particular to a novel spray-washing and material-throwing type dehydrating machine. Background Art

[0002] The plastic recycling industry is an important industry for global environmental protection and resource recycling. With the widespread application of plastics in many fields such as packaging, construction, automobiles, electronics, etc., the amount of plastic waste is also increasing rapidly. The goal of the plastic recycling industry is to collect and convert these wastes into reusable resources to reduce dependence on non-renewable resources such as crude oil, reduce environmental pollution, reduce greenhouse gas emissions, and promote sustainable economic development. The material-throwing dehydrator plays a very critical role in the plastic recycling industry. Its main function is to quickly and efficiently throw out the water in plastic materials (such as fragments, particles, etc.) through centrifugal force, so as to achieve the purpose of dehydration. During the operation of the existing material-throwing dehydrator, a large amount of solid particles and impurities will accumulate on the screen. If it is not cleaned in time, the screen aperture will gradually decrease, thereby affecting the dehydration effect. The screen needs to be frequently disassembled and maintained, which is costly; and stains, grease, cleaning agents, etc. still remain on the surface of the plastic bottle pieces, affecting the quality of the final product. Therefore, those skilled in the art provide a new type of spray-washing material-throwing dehydrator to solve the problems raised in the above background technology. Summary of the invention

[0003] The object of the present invention is to provide a novel spray-washing and throwing-off type dehydrator to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: it comprises a dehydrator body, a box, a screen and a spray washing assembly; a spray washing assembly is arranged above the screen of the dehydrator body, and the spray washing assembly comprises a first spray pipe, an equal-diameter tee, a second spray pipe, a 90° elbow, a third spray pipe, a flexible joint and a fourth spray pipe; the water outlet end of the first spray pipe is connected with an equal-diameter tee, the two ends of the equal-diameter tee are respectively connected with the second spray pipe, the ends of the second spray pipe are respectively connected with the third spray pipe through 90° elbows, and the third spray pipe is connected with the fourth spray pipe through a flexible joint; the spray washing assembly is installed in the box of the dehydrator body, and a hole is opened on the box, and the first spray pipe passes through the hole and is connected to an external high-pressure water pump; the third spray pipe and the fourth spray pipe are provided with cleaning holes, and the cleaning holes are located on the outside of the horizontal cross-section of the third spray pipe and the fourth spray pipe, and form an angle α with the horizontal cross-section.

[0005] Furthermore, the angle α between the cleaning hole and the horizontal cross-sections of the third spray pipe and the fourth spray pipe is 28°~32°.

[0006] Furthermore, the length of the spray washing assembly is consistent with the length of the box.

[0007] After adopting the above structure, the beneficial effects produced by the present invention are as follows: a new type of spray-washing and material-throwing dehydrator described in the present invention performs spray washing before dehydration, which can effectively remove stains, grease, detergent residues, etc. on the surface of plastic bottle pieces, so that moisture can be better removed in the subsequent dehydration process; after dehydration, the solid particles and impurities on the screen are promptly rinsed clean to improve the cleaning efficiency; the plastic bottle pieces after spray washing will be cleaner, which helps to improve the quality of the final product; spray washing can remove most of the pollutants before dehydration, reducing the pollution and blockage of the dehydrator screen, thereby reducing the maintenance frequency and maintenance cost; the spray washing component automatically cleans the screen without manual operation, reducing the labor intensity of workers, and high-pressure water flow cleaning can avoid damage to the screen caused by manual cleaning.
