Description

Technical Field

[0001] This utility model relates to the field of PE material technology, specifically to a PE raw material processing and mixing device. Background Technology

[0002] PE is a common plastic, and products made from it have the characteristics of corrosion resistance, crack resistance, high pressure resistance, and light weight. Therefore, it is widely used in various fields. In order to avoid the instability of product performance and inconsistent quality caused by the agglomeration or uneven distribution of PE raw materials, it is necessary to mix them thoroughly.

[0003] Because PE raw materials have high hygroscopicity, improper storage can cause moisture to accumulate or clump, affecting the mixing effect and potentially leading to problems such as surface bubbles, whitening, and breakage in subsequent products, thus reducing product quality. In addition, raw materials containing moisture tend to adhere to the inner wall of the mixing device, requiring subsequent cleaning. The common solution is to clean the inner wall of the mixing device using a scraper linked to the mixing mechanism. However, this operation can easily damage the inner wall of the mixing drum in the long run, and the contact between the scraper and the inner wall of the drum may also affect the operating speed of the mixing mechanism. Therefore, a PE raw material processing mixing device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a PE raw material processing and mixing device to solve the problems of poor performance of existing PE raw material processing and mixing devices when mixing PE raw materials with moisture, and the inconvenience of cleaning the raw materials adhering to the inner wall.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PE raw material processing and mixing device includes a main body, a mixing motor, a mixing blade, an air conveying section, an exhaust section, and a control box.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A PE raw material processing and mixing device includes a main body 1, a mixing motor 2, a mixing blade 3, an air conveying section 4, an exhaust section 5, and a control box 6. The main body 1 includes a base 11, a cylinder 12 fixedly connected to the upper side of the base 11, a feed hopper 13 fixedly connected to the upper opening of the cylinder 12, a limit guide ring 14 fixedly connected to the upper inner wall of the cylinder 12, a discharge valve pipe 15 connected to the lower side of the cylinder 12, a motor 2 fixedly connected to the upper side of the cylinder 12, a mixing blade 3 fixedly connected to the end of the output shaft of the motor 2 inside the cylinder 12, and an air conveying section 4 installed on the upper side of the cylinder 12, the air conveying section 4 including an exhaust valve fixed to the upper side of the cylinder 12. Pump 41, the front side of the air pump 41 is connected to an air supply pipe 42, the front end of the air supply pipe 42 is connected to an electric heating box 43, the front side of the electric heating box 43 is connected to a diversion pipe 44, the left and right ends of the diversion pipe 44 are both set through the upper cylinder plate of the cylinder 12 and the limiting guide ring 14, an exhaust part 5 is installed on the inner side of the cylinder 12, the exhaust part 5 includes a transfer sleeve 51 rotatably connected to the limiting guide ring 14, the lower side of the transfer sleeve 51 is connected to an air supply frame 52, the lower end of the stirring blade 3 is fixedly connected to the upper plane of the air supply frame 52, and a number of jet nozzles 53 arranged at equal intervals are fixedly connected to the side of the air supply frame 52 away from the stirring blade 3.

[0028] A control box 6 is installed on the right side of the cylinder 12. The control box 6 is electrically connected to the motor 2, the air pump 41, and the electric heating box 43. This configuration allows the control box 6 to control the motor 2, the air pump 41, and the electric heating box 43. The center of the limiting guide ring 14 is aligned with the center of the output shaft of the motor 2. This configuration allows the motor 2 to drive the air conveying frame 52 and the transfer sleeve 51 to rotate with the limiting guide ring 14 as the limiting guide. The lower part of the inner cavity of the cylinder 12 has a tapered structure that is wider at the top and narrower at the bottom. This configuration facilitates subsequent material discharge from the cylinder 12. The air conveying frame 52 consists of a pair of vertical pipes, a pair of inclined pipes, and a central connecting block. There is a gap between the air conveying frame 52 and the inner wall of the cylinder 12, and there is also a gap between the jet nozzle 53 and the inner wall of the cylinder 12. This configuration prevents the rotating air conveying frame 52 and jet nozzle 53 from contacting the inner wall of the cylinder 12, thus diverting the flow. Pipe 44 is connected to the transfer housing 51, allowing the branch pipe 44 to supply gas into the transfer housing 51. The limiting guide ring 14 is a ring structure with an inverted T-shaped cross-section, and the transfer housing 51 is a ring structure with an open top. The upper end face of the transfer housing 51 is in contact with the upper inner wall of the cylinder 12, and the inner wall of the transfer housing 51 is in contact with the outer end face of the limiting guide ring 14. This arrangement allows the limiting guide ring 14 to limit the transfer housing 51. At the same time, air leakage is avoided between the transfer sleeve 51 and the limiting guide ring 14; a discharge port is provided on the lower side of the cylinder 12, and the discharge valve pipe 15 is located on the lower side of the discharge port of the cylinder 12. The discharge valve pipe 15 consists of a discharge pipe and a regulating valve installed on the discharge pipe. A gap is provided between the air conveying frame 52 and the discharge port of the cylinder 12. This setting allows the raw material in the cylinder 12 to be discharged from the discharge valve pipe 15 without interference from the air conveying frame 52.

[0029] Workflow: The mixing device operates as follows to mix various PE raw materials. Note that all electrical components of this equipment are externally powered and centrally controlled by control box 6. First, the PE raw materials are fed into the cylinder 12 through the feed hopper 13. Then, motor 2 is started using control box 6. Motor 2 drives the mixing blade 3 to rotate. The rotation of the mixing blade 3 mixes the PE raw materials in the cylinder 12 and simultaneously drives the air conveying frame 52 and the transfer sleeve 51 to rotate with the limit guide ring 14 as the limit guide. Simultaneously, the air pump 41 is started by control box 6 to draw air outwards. The drawn airflow is transported to the electric heating box 43 through the air conveying pipe 42. The electric heating box 43 heats the gas, turning it into a high-temperature airflow. The high-temperature airflow then enters the transfer sleeve 51 through the diversion pipe 44 and is transported to the air conveying frame 52, finally exiting from the transfer sleeve 51. The jet nozzle 53 ejects a high-temperature airflow that contacts the inner wall of the cylinder 12 and circulates across the entire inner wall of the cylinder 12 as the air conveying frame 52 rotates. This effectively cleans the material and prevents it from adhering to the inner wall of the cylinder 12. Simultaneously, the high-temperature airflow moves within the cylinder 12 and is eventually discharged from the feed hopper 13. During this process, the movement of the high-temperature airflow increases the fluidity of the PE raw materials, thereby improving the mixing effect of the equipment. On the other hand, it dries the PE raw materials and carries away the moisture from the raw materials from the cylinder 12. Through the above operations, the PE raw material processing and mixing device cleans the cylinder wall during the mixing process without damaging the cylinder wall. At the same time, it dries the PE raw materials and improves the mixing effect, effectively solving the problems of poor performance of existing PE raw material processing and mixing devices when mixing PE raw materials with moisture and the inconvenience of cleaning the material adhering to the inner wall.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
