Description

Technical Field

[0001] The present application relates to the technical field of plastic processing equipment, and in particular to a plastic pellet cleaning device. Background Art

[0002] During plastic processing, during equipment commissioning and production, some waste materials such as unqualified products will be generated. After these waste materials are crushed, recycled materials are obtained. The recycled materials are added to the raw materials in a certain proportion, which can reduce the production costs of enterprises. However, unqualified products and waste materials are usually piled up in waste bins or stored in the open air because they are not processed in time, resulting in dust attached to the upper part. Excessive dust mixed in the plastic can easily lead to a decrease in the voltage resistance of the molded power pipe. Therefore, after the waste is crushed, the company will also arrange personnel to wash the plastic particles and wash away the dust. However, manual cleaning is inefficient. For example, a high-transparency ABS plastic pellet production cleaning machine disclosed in application number 202221455478.X adopts a drum cleaning method, and the loading and discharging speeds are slow, the production efficiency is low, and the plastic pellets are easy to adhere to the inner wall after being wet, resulting in incomplete discharge. For the crushed plastic pellets, it is only necessary to simply wash away the dust. The longer loading and discharging process will reduce the cleaning speed. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a plastic pellet cleaning device to solve the problems of slow loading speed and easy adhesion of plastic pellets to the inner wall in the prior art.

[0004] This application is implemented through the following technical solutions:

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a plastic pellet cleaning device, including: a tank body 1, a spray ring 2, and a stirring paddle 3. The lower part of the tank body 1 is connected to the ground through a support frame 4; a cover body 5 is provided on the upper part of the tank body 1, and the cover body 5 is fixed to the tank body 1 by bolts; a stirring motor 6 is provided on the upper part of the cover body 5, and the stirring paddle 3 is installed in the tank body 1. The lower part of the stirring paddle 3 is connected to the bottom of the tank body 1 through a sleeve, and the upper part of the stirring paddle 3 is connected to the output shaft of the stirring motor 6; the spray ring 2 is installed below the cover body 5, and the stirring paddle 3 passes through the middle part of the spray ring 2, and a plurality of spray heads 7 are provided on the upper part of the spray ring 2.

[0022] During cleaning, workers feed the crushed plastic pellets into the feed hopper 9 by manual feeding or a negative pressure pump. The plastic pellets fall into the tank body 1 under the action of gravity. At the same time, the water inlet pipe 8 adds clean water into the tank body 1. After enough clean water is added, the stirring motor 6 is started. The stirring motor 6 drives the stirring paddle 3 to rotate, so that the plastic pellets rotate together with the clean water. The inner wall of the tank body 1 is provided with a protrusion, so that the water flow deflects at the protrusion during rotation, so that the plastic pellets collide with each other, thereby improving the cleaning efficiency. After stirring for a period of time, the dust attached to the plastic pellets enters the water flow. At this time, part of the water is discharged through the drain pipe 11, and then clean water is injected to After the second cleaning, open the valve on the discharge pipe 10 to discharge the clean water and plastic particles into the drain basket. The bottom and side of the drain basket are provided with water-permeable holes. The water drained from the drain basket flows back to the circulating water pool through the ditch, while the cleaned plastic particles remain in the drain basket. After a period of draining and drying, the plastic particles are sent to the drying tower, and after drying, they are mixed into the raw materials for the production of plastic products such as power pipes. The plastic particles after cleaning have less dust content, which can improve the voltage resistance performance of the power pipe and reduce the number of pitting on the appearance surface when making plastic parts, thereby improving product quality.

[0023] During discharge, since the discharge pipe 10 is connected to the tank body 1 along a tangent line, the rotating water flow carries the plastic particles and is quickly discharged from the discharge pipe 10 under the action of inertia. During discharge, the water inlet pipe 8 supplies water to the spray ring 2 to flush the interior of the tank body 1 to prevent the plastic particles from remaining in the tank body 1 and improve the discharge efficiency.

[0024] The dust content in plastic pellets is generally not high, and the water after cleaning can be recycled after filtration and sedimentation, reducing water consumption.

[0025] Specifically, a water inlet pipe 8 is provided on the upper part of the cover body 5, one end of the water inlet pipe 8 is connected to the clean water tank through a circulation pump, and the other end of the water inlet pipe 8 is connected to the spray ring 2 after passing through the cover body 5. The water inlet pipe 8 is used to add clean water to the tank body 1 so as to clean the dust on the plastic particles with clean water and reduce the content of dust impurities.

[0026] In a specific embodiment, the cover body 5 has a feed port on the top, and a feed hopper 9 is installed on the top of the feed port to facilitate the rapid addition of plastic pellets into the tank body 1 and improve the efficiency of loading.

[0027] In a specific embodiment, a discharge pipe 10 and a drain pipe 11 are provided at the lower part of the tank body 1. The discharge pipe 10 and the drain pipe 11 are both connected to the bottom of the inner cavity of the tank body 1. The discharge pipe 10 is connected to the tank body 1 along a tangent. During discharge, after the discharge valve is opened, the plastic particles can enter the discharge pipe 10 along the tangent direction under the action of inertia to complete the discharge, thereby increasing the discharge speed.

[0028] Preferably, a filter screen 12 is provided at the connection between the drain pipe 11 and the bottom of the tank body 1. The filter screen 12 is 5 cm to 10 cm higher than the bottom of the tank body 1. The raised filter screen 12 can increase the filtering area and increase the drainage speed. At the same time, behind the raised filter screen 12, plastic particles and water flow can flush it during cleaning to prevent the filter screen 12 from being blocked.

[0029] Preferably, a backwash pipe 13 is provided on the drain pipe 11, and backwash water can be passed into the drain pipe 11 to backwash the filter screen 12 to prevent the filter screen 12 from being blocked.

[0030] Preferably, the spray head 7 is directed toward the lower part of the cover 5, the inner wall of the tank 1, and the stirring paddle 3, respectively. When discharging, the water inlet pipe 8 supplies water to the spray ring 2 to flush the interior of the tank 1, thereby preventing plastic particles from remaining in the tank 1 and improving the discharging efficiency. In addition, since the cover 5 is provided with a feed port, the spray head 7 avoids this position to prevent clean water from splashing out of the tank 1.

[0031] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
