Description

Technical Field

[0001] This utility model relates to the field of PVC waste material particle cleaning technology, specifically a PVC waste material cleaning device. Background Technology

[0002] Polyvinyl chloride (PVC) is a polymer formed by the free radical polymerization of vinyl chloride monomer under the action of initiators such as peroxides and azo compounds, or under the action of light and heat. It appears as a white powder, is non-toxic and odorless, and has a relative molecular mass of generally 50,000 to 110,000 (pure PVC produced in industry). Its relative density is 1.35 to 1.45. It has very low water absorption and air permeability (pure PVC). It is insoluble in water, gasoline, alcohol, and vinyl chloride, but soluble in ketones, esters, and chlorinated hydrocarbon solvents.

[0003] Polyvinyl chloride (PVC) is a widely used plastic material, and the recycling of its waste materials is of great significance to environmental protection and resource recycling. Traditional PVC waste particle cleaning methods mostly use a single stirring shaft structure, which makes it difficult to thoroughly clean the PVC waste particles, resulting in poor cleaning effect and affecting the quality of subsequent recycling. Therefore, a PVC waste particle cleaning device is needed. Utility Model Content

[0021] 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.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A PVC waste material cleaning device includes a cleaning tank 1, and a cleaning mesh cylinder 2 is installed inside the cleaning tank 1.

[0025] Four stirring shafts 3 are rotatably connected to the top of the inner part of the cleaning screen cylinder 2. The top of each stirring shaft 3 passes through the cleaning screen cylinder 2 and extends to its outside. A synchronous wheel 4 is fixedly connected to the top of each stirring shaft 3. Multiple sets of stirring blades 5 are fixedly connected to both ends of each stirring shaft 3. The four synchronous wheels 4 are connected to each other by a synchronous belt 6. A first motor 7 is installed on the top of the cleaning screen cylinder 2.

[0026] The output shaft of the first motor 7 is fixedly connected to one of the stirring shafts 3, and the four stirring shafts 3 are arranged in a ring array.

[0027] The front and rear ends of the cleaning net cylinder 2 are respectively fixedly connected with support plates, and one end of each support plate is fixedly connected to the cleaning box 1.

[0028] A discharge pipe 8 is fixedly connected to the left side of the cleaning tank 1, and a valve is installed on the discharge pipe 8. A feed hopper 9 is installed on the top of the cleaning screen cylinder 2.

[0029] Through the above technical solution, the cleaning tank 1 is the external container of the entire device, providing space for the cleaning process. The cleaning mesh cylinder 2 is located inside the cleaning tank 1 and is the place where PVC waste particles are cleaned. The mesh structure of the mesh cylinder allows the cleaning water to fully contact the PVC waste particles during the cleaning process, while facilitating the discharge of wastewater. Four stirring shafts 3 are rotatably connected to the inner top of the cleaning mesh cylinder 2, arranged in a circular array. The synchronous pulley 4 at the top of each stirring shaft 3 is connected by a synchronous belt 6. When the first motor 7 drives one of the stirring shafts 3 to rotate, the other three stirring shafts 3 will also rotate synchronously through the transmission of the synchronous belt 6. The multiple sets of stirring blades 5 at both ends of the stirring shafts 3 will stir the PVC waste particles and cleaning water in the cleaning mesh cylinder 2 when the stirring shafts 3 rotate, causing the PVC waste particles to tumble fully in the cleaning water. To achieve better cleaning results, the first motor 7 serves as the power source, with its output shaft fixedly connected to one of the stirring shafts 3, providing power for the rotation of the stirring shaft 3. This, in turn, drives the stirring blades to stir and clean the PVC waste material particles. The four stirring shafts 3 are arranged in a ring, covering the internal space of the cleaning screen cylinder 2, improving the uniformity of cleaning. The synchronous wheel 4 and the synchronous belt 6 ensure that the speed of each stirring shaft 3 is consistent. The support plates at the front and rear ends of the cleaning screen cylinder 2 fix the cleaning screen cylinder 2 inside the cleaning box 1, playing a role in supporting and fixing the cleaning screen cylinder 2, ensuring the stability of the cleaning screen cylinder 2 during the stirring process. The discharge pipe 8 on the left side of the cleaning box 1 is used to discharge the wastewater after cleaning. The valve can control the opening and closing of the discharge pipe, making it convenient to discharge wastewater at the appropriate time. The feed hopper 9 is located at the top of the cleaning screen cylinder 2 and is used to add the PVC waste material particles to be cleaned into the cleaning screen cylinder.

[0030] Example 2

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: a sleeve 10 is fixedly connected inside the cleaning screen cylinder 2, a spiral auger 11 is provided inside the sleeve 10, the top of the sleeve 10 penetrates through the cleaning screen cylinder 2 and extends to its outside, and a second motor 12 is fixedly connected to the top of the sleeve 10.

[0032] The bottom of the sleeve 10 is fixedly connected to the inner bottom wall of the cleaning screen cylinder 2, and the bottom of both ends of the sleeve 10 are respectively provided with feed ports.

[0033] The output end of the second motor 12 is fixedly connected to the spiral auger 11, and the top right side of the sleeve 10 is fixedly connected to the discharge pipe 13.

[0034] Through the above technical solution, the sleeve 10 is fixedly connected inside the cleaning screen cylinder 2, and its bottom is fixedly connected to the inner bottom wall of the cleaning screen cylinder 2. Feed ports are opened at both ends of the bottom. The spiral auger 11 is set inside the sleeve 10. When the second motor 12 drives the spiral auger 11 to rotate, the PVC waste particles in the cleaning screen cylinder 2 will enter the sleeve 10 through the feed port, thereby conveying the PVC waste particles entering the sleeve upward. The discharge pipe 13 on the top right side of the sleeve 10 is used to discharge the cleaned PVC waste particles conveyed by the spiral auger 11, realizing the automatic discharge of PVC waste particles and reducing manual intervention.

[0035] In actual operation, when this device is in use, firstly, PVC waste material particles to be cleaned are added to the cleaning screen cylinder 2 through the feed hopper 9, and an appropriate amount of cleaning water is injected into the cleaning tank 1. The first motor 7 is started, which drives one of the stirring shafts 3 to rotate. Through the transmission of the synchronous wheel 4 and the synchronous belt 6, the four stirring shafts 3 rotate synchronously. The stirring blades 5 stir the PVC waste material particles and the cleaning water to clean the PVC waste material particles. After cleaning, the valve on the discharge pipe 8 on the left side of the cleaning tank 1 is opened to discharge the wastewater. If the PVC waste material particles are not cleaned, more cleaning water can be added to clean them until they are clean. After the wastewater is discharged, the second motor 12 is started, which drives the spiral auger 11 to rotate. The PVC waste material particles in the cleaning screen cylinder 2 enter the sleeve 10 through the feed ports at the bottom of both ends of the sleeve 10, are conveyed upward by the spiral auger 11, and finally discharged from the device through the discharge pipe 13 at the top right side of the sleeve 10.
