Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to a device for cleaning raw materials for producing PVC plastic particles. Background Art

[0002] Plastics are polymer compounds made of monomers through addition polymerization or condensation polymerization, commonly known as plastics or resins. They can freely change their composition and shape. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In the plastic recycling process, the cleaning and classification of plastics are crucial. In the existing technology, plastics often need to be classified after cleaning. This process is cumbersome and wastes a lot of manpower and material resources. Summary of the invention

The installation box is arranged above the chassis and fixedly connected to the upper surface of the chassis. The feed pipe is arranged obliquely, arranged on the side of the installation box, fixedly connected to the side of the installation box, and communicated with the inside of the installation box. The first discharge port is arranged on the side of the installation box away from the feed pipe. The screening device is arranged inside the installation box, arranged below the feed pipe, arranged above the first discharge port, and connected to the installation box. The cleaning device is arranged above the screening device, the cleaning device is connected to the installation box, connected to the chassis, and fixedly connected to the screening device. The transportation device is arranged on the side of the installation box away from the feed pipe, arranged above the chassis, and fixedly connected to the upper surface of the chassis. The stopping device is arranged on the side of the installation box close to the transportation device, arranged above the transportation device, fixedly connected to the side of the installation box close to the transportation device, fixedly connected to the screening device, and fixedly connected to the transportation device.

The drying machine is arranged above the transport device and fixedly connected with the transport device.

[0004] When the plastic particles need to be cleaned, the staff pours the plastic particles to be cleaned from the feed pipe into the installation box. After the plastic particles enter the installation box, they fall onto the screening device. Then the staff opens the cleaning device, and the cleaning device cleans the plastic particles. When the staff opens the cleaning device, the staff opens the screening device, and the screening device starts to rotate up and down. The plastic particles on the screening device that do not meet the required size fall into the installation box during the rotation of the screening device, and the plastic particles that meet the size requirements will pass through the screening device and fall onto the transport device from the first discharge port. When the screening device starts to rotate up and down, the screening device will drive the cleaning device to rotate up and down, so that the cleaning device and the screening device maintain a certain distance, so that the cleaning device can clean the plastic particles rolling down from the screening device. At the same time, the cleaning device will limit the plastic particles to prevent the plastic particles from blocking the first discharge port. When the screening device rotates up and down, it will drive the stop device to control the movement and stop of the transport device. When the plastic particles pass through the first discharge port, the transport device starts to move. When the plastic particles cannot pass through the first discharge port, the screening device will stop the transport device through the stop device. When the plastic particles fall into the transport device, the transport device drives the plastic particles to move to the bottom of the dryer, and the dryer dries the plastic particles. Then the transport device transports the plastic particles to the collection device, and the water generated by the cleaning device and the water generated by the plastic particles passing through the transport device will flow into the collection device.

[0023] Beneficial effects of the present invention: 1. When the plastic particles need to be cleaned, the staff pours the plastic particles to be cleaned from the feed pipe into the installation box. After entering the installation box, the plastic particles fall onto the screening device. Then the staff turns on the cleaning device, and the cleaning device cleans the plastic particles. When the staff turns on the cleaning device, the staff turns on the screening device, and the screening device rotates up and down. The plastic particles on the screening device that do not meet the required size will pass through the screening device and fall into the installation box, and the plastic particles that meet the size requirements will pass through the screening device and fall from the first discharge port to the transport device. This achieves the cleaning and screening of the plastic particles.

[0024] 2. When the screening device rotates, the screening device will drive the cleaning device to rotate together. The cleaning device and the screening device maintain a fixed distance, so that the plastic particles can be cleaned when they roll down the screening device to prevent omissions. At the same time, the cleaning device can play a role in limiting the plastic particles, preventing them from accumulating and blocking the discharge port when they roll down the screening device.

[0025] 3. The screening device performs a periodic motion of alternating static and rotating motions. When the screening device is static, the screening device clamps the transport device through the stop device to stop the transport device from moving, thereby increasing the drying time of the plastic particles on the transport device, preventing water stains from remaining on the surface of the plastic particles, and facilitating subsequent processing.

[0026] 4. When the screening device rotates, the stopping device and the transport device begin to separate. When the plastic particles pass through the first discharge port, the stopping device separates from the transport device and the transport device starts to move, so that the plastic particles are evenly laid on the conveying device, which is convenient for subsequent processing by the staff.
