Description

Technical Field

[0001] This utility model relates to the field of plastic cleaning and drying technology, specifically to a plastic cleaning and drying device. Background Technology

[0002] Plastics are high molecular weight compounds polymerized from monomers through addition or condensation reactions. They are commonly known as plastics or resins and their composition and shape can be freely changed. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastic masterbatch is a concentrated form made by adding plastic additives to resin in excessive amounts.

[0003] During the production of plastic masterbatch, dust and powder inevitably adhere to the masterbatch. Before bagging, slag removal is required to avoid excessive slag content in the masterbatch. Therefore, the plastic masterbatch also needs to be washed and dried with water. Generally, the density of plastic masterbatch is less than that of water. Since the plastic floats on the water, it is easier to manage and clean, and no additional equipment is needed to support or fix the plastic.

[0004] Existing equipment typically handles the cleaning, washing, and drying of plastic masterbatches independently. First, the washed plastic is drained of excess water, and then it is transferred to the drying equipment for drying. Not only is the plastic re-contaminated during the transfer process, but the process of draining the water and transferring the equipment also wastes a lot of time, resulting in low efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2This application proposes a plastic washing and drying equipment, including a washing cylinder 1 with a feed inlet 11 at the top, a stirring structure 2 at the bottom of the washing cylinder 1, a discharge port 12 at the upper side of the right side wall of the washing cylinder 1 corresponding to the receiving plate, a sealable cover plate 3 at the discharge port 12, a support frame 4 at the right side of the washing cylinder 1, a filter plate 5 at the upper side of the support frame 4, a drying component 6 at the upper side of the support frame 4 corresponding to the upper side of the filter plate 5, a water receiving trough 7 fixed in the middle of the support frame 4, a water pump 8 in the water receiving trough 7, a water supply pipe 9 connected to the water outlet of the water pump 8, the water supply pipe 9 extending to the top of the washing cylinder 1 and through the washing cylinder 1 to its interior;

[0024] Specifically, during plastic cleaning, an appropriate amount of water is first injected into the water receiving tank 7 and the cleaning drum 1. The liquid level inside the cleaning drum 1 should be at the discharge port 12. The plastic to be cleaned is then placed into the inlet 11 and stirred by the stirring component to clean the plastic. After cleaning, the cover plate 3 is opened, allowing the water to carry the cleaned plastic out of the discharge port 12. Since the density of plastic is less than that of water, it will float on the water surface. Therefore, the plastic will flow out of the discharge port 12 with the water flow and enter the filter plate 5, filtering the excess water into the water receiving tank 7. The drying component 6 is then used to dry the plastic. No transfer is required, which greatly improves the efficiency of plastic cleaning. At the same time, the water entering the water receiving tank 7 is pumped back into the cleaning drum 1 by the water pump 8. This ensures that the liquid level inside the cleaning drum 1 is at the discharge port 12, ensuring continuous water output and material discharge. It also allows for water recycling, saving water resources.

[0025] Further details can be found here. Figure 1 The stirring structure 2 includes a rotating shaft 21 rotatably connected to the inner bottom side of the cleaning cylinder 1. The top plate of the rotating shaft 21 is provided with a ring array of stirring blades 22.

One end of the rotating rod 25 is provided with a second bevel gear 26 that meshes with the first bevel gear 24, and the other end is rotatably inserted into the side wall of the movable cavity 23. A drive motor 27 that can drive the rotating rod 25 is provided on the side wall of the cleaning cylinder 1 corresponding to the insertion point of the rotating rod 25.

[0026] The drive motor 27 drives the rotating rod 25 to rotate, which in turn engages with the first bevel gear 24 and the second bevel gear 26, thereby driving the rotating rod 25 and the stirring blade 22 to rotate, so that the plastic placed in the cleaning cylinder 1 is thoroughly cleaned in water.

[0027] Meanwhile, an ultrasonic generator 28 is also provided at the bottom of the cleaning cylinder 1 to improve its cleaning effect. The ultrasonic generator 28 and its working method are existing technologies.

A fan 63 is provided on the horizontal plate 61 corresponding to the filter plate 5, and an electric heating wire 64 is provided on the lower side of the horizontal plate 61 corresponding to the fan 63. The fan 63 and the electric heating wire 64 work together to blow hot air onto the plastic particles on the filter plate 5 to dry them quickly.

[0029] The filter plate 5 is equipped with baffles 51 on both the front and rear sides to ensure that the plastic particles do not fall from the sides. Vibration motors 52 are installed on the opposite sides of the two baffles 51. The left and right ends of the lower side of the filter plate 5 are connected to the upper side of the support frame 4 by springs 53, which vibrate it during drying to accelerate the drying process of the plastic.

[0030] Meanwhile, the filter plate 5 is inclined downward from left to right. A baffle plate 54 is provided on the upper side of the filter plate 5 near the right end. The front and rear sides of the baffle plate 54 can be slidably inserted on the opposite side of the two baffle plates 51. The baffle plate 54 can block water and plastic from flowing out when the washing cylinder 1 is discharging. After drying, it can be removed to facilitate the discharge of dried plastic.

[0031] Further details can be found here. Figure 1 A filter screen 71 is installed in the water tank 7 corresponding to the water pump 8 to filter the water in the water tank 7 and ensure the cleanliness of the circulating water.

[0032] Further details can be found here.
