Description

Technical Field

[0002] Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent, thermoplastic, lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high-wear resistance processing performance. However, polypropylene also has many disadvantages that affect its series of engineering applications. The large molding shrinkage of polypropylene, easy brittle cracking at low temperatures, insufficient toughness, and low wear resistance have greatly restricted the development of polypropylene. Therefore, polypropylene must be modified.

An inspection door is fixedly installed on the base surface of the motor box, and a transparent window is fixedly installed on the base surface of the stirring box. Discharge channels are fixedly installed on both sides of the stirring box, and a push baffle is fixedly installed on the top of the discharge channel. An agitator is fixedly installed inside the stirring box. A first weighing silo, a second weighing silo, a third weighing silo, and a fourth weighing silo are opened inside the batching box. A material guide through hole is opened at the center of the bottom of the batching box, and electronic hopper scales are fixedly installed around the material guide through hole.

[0004] However, it has been found that when the above-mentioned device is in use, the purpose of automatic quantity control can be achieved through an electronic hopper scale and a weighing silo.

[0005] Therefore, it is necessary to provide a new modified polypropylene batching device to solve the above technical problems. Utility Model Content

Therefore, the features limited to "one", "two", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0023] In the specific implementation process, Figure 1-Figure 3 As shown, the modified polypropylene batching device includes a mixing box 1 for mixing polypropylene raw materials and a box cover 2 buckled on the top of the mixing box 1, a plurality of batching boxes are respectively arranged on the top of the box cover 2, and a feed pipe 3 connected to the mixing box 1 is arranged at the bottom of each of the plurality of batching boxes. A valve 1 4 and a valve 2 5 are arranged opposite to each other up and down on each of the plurality of feed pipes 3. A liquid adding pipe 6 is also connected to one side of the feed pipe 3, and the liquid adding pipe 6 is located between the valve 1 4 and the valve 2 5. A valve 3 9 is arranged on the outer surface of the liquid adding pipe 6. A scale 10 is also arranged on the feed pipe 3 between the valve 1 4 and the valve 2 5. The scale 10 is for better controlling the batching amount. The polypropylene raw material is first added into the mixing box 1, and magnesium hydroxide, silane coupling agent and polytetrafluoroethylene powder are added into the batching box. An appropriate amount of water is added through the liquid adding pipe 6 for mixing and modification.

[0025] It should be noted that the use of the feed pipe 3 in conjunction with the liquid adding pipe 6 may include the following:

[0026] 1. The liquid in the liquid adding pipe 6 can be water.

[0027] 2. The liquid in the liquid adding pipe 6 can be water. When the valve 2 5 and the valve 3 9 are opened at the same time, the water is first input into the feeding pipe 3 through the liquid adding pipe 6 by means of water pump pressure increase, and then the valve 1 4 is opened, and the ingredients fall into the mixing box 1 along with the water, which is suitable for the situation where multiple ingredients are mixed with the polypropylene raw material at the same time.

[0028] 3. The liquid in the liquid adding pipe 6 can be water. When the ingredients fall into the mixing box 1, the valve 1 4 can be closed, and the valve 2 5 and the valve 3 9 can be opened to add water into the mixing box 1.

[0029] Specifically, the water pump is an external device, and one end of the liquid adding pipe 6 is connected to the water outlet of the water pump.

[0030] The material box includes a hopper 7 and a material cover 8. The inner cavity of the hopper 7 is provided with a through hole 15 connected to the inner cavity of the feeding tube 3. One end of the material cover 8 is hinged to the top end of the hopper 7. Both the hopper 7 and the material cover 8 are transparent.

The shaft rod 13 is rotated by starting the driving motor 11, and the rotation of the shaft rod 13 simultaneously drives the plurality of stirring blades 14 to rotate. It should be noted that the stirring blades 14 and the shaft rod 13 are detachably mounted by bolts.

[0034] The working principle provided by the utility model is as follows: when the device is used, first add the polypropylene raw material into the mixing box 1, add magnesium hydroxide, silane coupling agent and polytetrafluoroethylene powder into the ingredient box, add an appropriate amount of water through the liquid adding pipe 6 for mixing and modification, the liquid in the liquid adding pipe 6 can be water, when the valve 1 4 and the valve 2 5 are closed and the valve 3 9 is opened, the water is input into the feeding pipe 3 through the liquid adding pipe 6 by means of water pump pressurization, and then the valve 3 9 is closed, and the valve 1 4 is opened to mix the water and the ingredients, and the scale 10 is observed to control the ingredient amount. After mixing for a certain period of time, the valve 2 5 is opened, and the mixed ingredients fall into the mixing box 1, and the shaft 13 is rotated by starting the driving motor 11, and the rotation of the shaft 13 simultaneously drives the multiple stirring blades 14 to rotate for mixing and modification.
