Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment, specifically a mixing device for processing modified polypropylene. Background Technology

[0002] Modified polypropylene (PP) is refined from polypropylene and various organic and inorganic materials using a special composite technology. In concrete, the product forms a three-dimensional, randomly distributed network of support, hindering the development of microcracks formed in the early stages of hardening. However, during the heating and mixing process of modified PP, existing mixing devices often fail to promptly remove adhering PP from their surfaces, leading to solidification and increased cleaning difficulty. Therefore, this paper proposes a mixing device for processing modified PP that can quickly remove adhering substances. Utility Model Content

[0003] The purpose of this invention is to provide a stirring device for processing modified polypropylene in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a stirring device for processing modified polypropylene, comprising strip-shaped stirring plates and a scraping component for scraping material, wherein two strip-shaped stirring plates are respectively slidably inserted into two rectangular holes, and the two rectangular holes are symmetrically opened on a rotating plate, the top ends of the two strip-shaped stirring plates are connected to each other by a connecting plate, and the middle part of the connecting plate is installed on the shaft end of a motor, the motor is installed at one end of a fan-shaped plate, and two electro-hydraulic push rods are symmetrically installed on one side of the back of the fan-shaped plate, the top two sides of the scraping component are respectively installed on both sides of the bottom opening of the same rectangular hole, and the scraping component has a portion of the strip-shaped stirring plate slidably inserted inside.

[0005] Preferably, the rotating plate is rotatably connected to the central annular hole of the ring frame via a bearing.

[0006] Preferably, the ring frame is installed at the opening of the mixing tank, and the guide rod located on the top side of the ring frame is slidably connected to the guide hole located on the sector plate.

[0007] Preferably, an outlet pipe is connected to the bottom of the mixing tank.

[0008] Preferably, a control valve is installed on the outlet pipe.

[0009] Preferably, the scraper is much higher than the highest surface of the material being mixed.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the electro-hydraulic actuator extends and pulls the motor and its connecting parts connected to the fan-shaped plate upward, causing the strip agitator to move up and detach from the material being stirred. Combined with the sliding contact between the edge of the corresponding port of the scraper and the surface of the strip agitator, it is beneficial to scrape off the material adhering to the strip agitator. At the same time, the motor drives the strip agitator to rotate continuously, so as to use centrifugal force to throw off the adhering material, which enhances the strength of the scraping and detachment, improves the cleaning effect of scraping the material from the strip agitator, and solves the problem of inconvenient cleaning of the material adhering to the surface of the stirring structure.

[0019] Please see Figure 1-3 As shown, a stirring device for processing modified polypropylene includes strip-shaped stirring plates 1 and scraper components 4 for scraping material. The two strip-shaped stirring plates 1 are slidably inserted into two rectangular holes 210, and the two rectangular holes 210 are symmetrically opened on a rotating plate 2. The top ends of the two strip-shaped stirring plates 1 are connected to each other by a connecting plate 3, and the middle part of the connecting plate 3 is installed on the shaft end of a motor 5. The motor 5 is installed at one end of a fan-shaped plate 7, and two electro-hydraulic push rods 9 are symmetrically installed on one side of the back of the fan-shaped plate 7. The top two sides of the scraper component 4 are respectively installed on both sides of the bottom opening of the same rectangular hole 210, and the scraper component 4 has a portion of the strip-shaped stirring plate 1 slidably inserted inside it.

[0020] The rotating plate 2 is rotatably connected to the central annular hole of the ring frame 6 via a bearing. The rotatable connection between the rotating plate 2 and the ring frame 6 ensures the responsiveness of the rotation between the rotating plate 2 and the strip stirring plate 1.

[0021] The ring frame 6 is installed at the opening of the mixing tank 10, and the guide rod 8 located on the top side of the ring frame 6 is slidably connected to the guide hole 710 located on the sector plate 7. By using the slidable connection between the guide rod 8 and the guide hole 710 located on the sector plate 7, the effect of vertical movement guidance is achieved.

[0022] The bottom of the mixing tank 10 is connected to an outlet pipe 12, and a control valve 11 is installed on the outlet pipe 12 to facilitate the discharge of the mixed materials.

[0023] Furthermore, the scraper 4 is much higher than the highest surface of the material being stirred.

[0024] Working principle: The motor 5 drives the two strip-shaped stirring plates 1 and the rotating plate 2 connected by the connecting plate 3 to rotate, thus completing the task of stirring the material inside the mixing tank 10.

[0025] When mixing is complete, since the polypropylene material is mostly mixed with other ingredients in a molten state, there is a problem of material adhering to the strip mixing plate 1. To address this, the electro-hydraulic actuator 9 extends and pulls the motor 5 and its connecting parts connected to the fan-shaped plate 7 upward, causing the strip mixing plate 1 to move upward and detach from the mixing material. Combined with the sliding contact between the edge of the corresponding port of the scraper 4 and the surface of the strip mixing plate 1, it is beneficial to scrape off the adhering material on the strip mixing plate 1. At the same time, the motor 5 drives the strip mixing plate 1 to rotate continuously, so as to use centrifugal force to throw off the adhering material, which enhances the strength of the scraping and detachment, improves the scraping and cleaning effect of the strip mixing plate 1, and solves the problem of inconvenient cleaning of the adhering material on the surface of the mixing structure.
