Description

Technical Field

[0001] The utility model relates to plastic processing equipment, in particular to a dust removal device for recycled plastic particles which is convenient for taking out materials. Background Art

[0002] Plastic recycled granules refer to granules processed from waste plastics and are one of the raw materials for the production of plastic products. Since there is a lot of dust on the surface of waste plastics, some dust may still remain on the surface of the recycled plastic granules after the waste plastics are recycled and granulated. This may affect the quality of the product when producing recycled plastic products. Therefore, the recycled plastic granules need to be dusted before being put into production.

[0003] Some existing plastic particle dust removal devices adopt a water flushing method to flush the plastic particles through continuous flowing water, which consumes a large amount of water and the dust removal of the recycled plastic particles is uneven. In this regard, a recycled plastic particle dust removal device with a publication number of CN219686231U is disclosed. The patent places the plastic particles to be cleaned in a fixed frame, and then drives the fixed frame to sink into a water storage tank filled with clean water by a telescopic cylinder. The stirring component continuously stirs the frame, thereby solving the problem that the dust removal effect of the existing recycled plastic particle dust removal device is poor, resulting in adverse effects on the use of the recycled plastic particles.

[0004] After the plastic particles of this patent are cleaned, it is necessary to first lift the fixed frame and leave the liquid surface, and fix the container under the fixed frame, and then remove the bolts and remove the bottom plate at the bottom of the fixed box to take out the materials. The material taking process is relatively cumbersome, and the weight of the plastic particles increases after falling into the container. It is more difficult for workers to move the container from the bottom of the fixed frame. Therefore, we need a recycled plastic particle dust removal device that is convenient for taking out materials. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 6As shown, the utility model discloses a dust removal device for recycled plastic particles that is convenient for material collection, including a cleaning box 1, wherein a cleaning chamber 11 is provided in the cleaning box 1. The cleaning box 1 is fixedly connected with a water inlet pipe 12 on the upper side of the side wall of the cleaning chamber 11, and a drain pipe 13 is fixedly connected to the lower end of the cleaning box 1, and a solenoid valve 14 is fixedly connected to the drain pipe 13 (it should be noted here that the operator can connect the water inlet pipe 12 and the drain pipe 13 to the conveying mechanism or the circulating filter device through a hose, which belongs to the well-known technology of those skilled in the art, which is not drawn in the figure, so it will not be described in detail here). Furthermore, a discharge port 15 is provided on one side of the cleaning box 1, and a movable door 2 is provided on the discharge port 15 of the cleaning box 1. A rotating filter plate 3 is rotatably connected to the bottom end of the cleaning chamber 11, and a lifting plate 4 is provided on the top of the cleaning box 1. A feeding port 41 for feeding plastic particles is provided on the lifting plate 4, and a stirring mechanism is provided on the lifting plate 4. A through hole 16 for the stirring mechanism to pass through is provided at the upper end of the cleaning chamber 11 of the cleaning box 1.

[0026] Among them, lifting cylinders 7 are symmetrically arranged on both sides of the cleaning box 1, and the lifting plate 4 is fixedly connected to the piston rod of the lifting cylinder 7. The stirring mechanism includes a plurality of servo motors 81 and a plurality of stirring paddles. The servo motors 81 are symmetrically arranged on both sides of the feed port 41, and the stirring paddles are respectively fixedly connected to the output shafts of each servo motor 81.

[0027] Furthermore, a rotating pin 31 is fixedly connected to the rotating filter plate 3, and the rotating pin 31 is rotatably connected to the cleaning chamber 11. A rotating cylinder 6 is fixedly connected to the outside of the cleaning box 1, and the piston rod of the rotating cylinder 6 extends into the cleaning chamber 11 and is fixedly connected to the rotating pin 31.

[0028] Furthermore, the lower end of the movable door 2 is fixedly connected with a hinged portion 22, and the lower end of the cleaning box 1 is fixedly connected with a hinged frame 17, and the hinged portion 22 is hinged to the hinged frame 17 through a pin shaft. The cleaning box 1 is fixedly connected with a limit frame 18 at the lower end of the hinged portion 22, and the limit frame 18 can limit the rotation angle of the movable door 2, so that the slope of the movable door 2 after opening can make the plastic particles slide smoothly into the container. Generally speaking, the opening angle of the movable door 2 is between 110 and 120 degrees. In addition, the cleaning box 1 is fixedly connected with an electromagnet 9 at the upper end of the discharge port 15, and the upper end of the inner wall of the movable door 2 is fixedly connected with a metal strip 23, and the movable door 2 is adsorbed on the electromagnet 9 through the metal strip 23. The above structure can not only ensure the sealing between the movable door 2 and the sealing ring plate 5 during the cleaning operation, but also prevent the plastic particles from being stuck in the gap between the movable door 2 and the sealing ring plate 5 when pouring, resulting in the movable door 2 being unable to close. Side baffles 21 are symmetrically arranged on both sides of the movable door 2 to prevent the plastic particles from falling from both sides of the movable door 2 to the ground and being contaminated when pouring.

[0029] The working principle of the utility model is as follows: before starting to clean, the stirring paddle is located in the cleaning chamber 11, and the operator puts the plastic particles to be cleaned into the cleaning chamber 11 through the feeding device (not shown in the figure, no further description is given here), and then fills the cleaning chamber 11 with water through the water inlet pipe until the liquid level covers the plastic particles, and then starts the servo motor 81, and the stirring paddle drives the plastic particles in the cleaning chamber 11 to rotate so as to remove dust, and the movable door 2 is in a closed state during the cleaning process;

[0030] After the dust removal is completed, the solenoid valve 14 is opened and the cleaning box 1 is drained. After the cleaning box 1 is drained, the lifting cylinder 7 drives the stirring paddle to move upward to make room for the rotating filter plate 3. The rotating cylinder 6 drives the rotating filter plate 3 to rotate upward. At the same time, the operator turns off the power supply of the electromagnet 9 and opens the movable door 2 to rotate the movable door 2 downward. The plastic particles in the cleaning chamber 11 are then dumped onto the movable door 2. The operator can push the plastic particles into the container by hand or tools such as push rods. There is no need for the operator to manually fix the container, and the operation is simple and convenient.

[0031] In addition, in order to ensure the sealing of the cleaning chamber 11 during the cleaning process, the discharge port 15 is fixedly connected to a sealing ring plate 5 on the side close to the cleaning chamber 11. When the movable door 2 is in a closed state, the movable door 2 is abutted against the sealing ring plate 5 to prevent water in the cleaning chamber 11 from leaking and causing waste of water resources. The sealing ring plate 5 is provided with a first fitting groove 51 on the side close to the rotating filter plate 3. The rotating filter plate 3 is pressed in the first fitting groove 51 to avoid the plastic particles being stuck in the gap between the rotating filter plate 3 and the sealing ring plate 5 when pouring, resulting in the rotating filter plate 3 being unable to rotate upward.
