Description

Technical Field

[0001] The utility model belongs to the technical field of polyvinyl chloride paste resin production equipment, in particular to a raw material dispersing equipment for preparing polyvinyl chloride paste resin. Background Art

[0002] PVC paste resin, also known as polyvinyl chloride paste resin, is mainly used in the production of gloves, artificial leather, coated cloth, flooring, conveyor belts, wallpaper, signs, shoes, toys, etc. In the production process of PVC paste resin, vinyl chloride monomer, deionized water, initiator and emulsifier are added to the dispersion tank in a certain proportion, and various fillers, diluents, wear-resistant agents, foaming agents and light stabilizers are added according to the needs of different products. In the process of adding raw materials, sufficient stirring is required. The existing equipment directly puts the raw materials into the stirring equipment for stirring, but does not disperse the raw materials, resulting in the raw materials directly piled up below the feed port, which is easy to cause local accumulation of raw materials during mixing and is not easy to mix evenly. The piled raw materials will affect the concentration during the reaction, thereby affecting the production rate and quality of the final product. Utility Model Content

[0042] like Figure 1-6 As shown, a raw material dispersing device for preparing polyvinyl chloride paste resin comprises a main body 1, on which a feed port 11 and a discharge port 12 are provided, wherein the feed port 11 is provided at the top of the main body 1, and the discharge port 12 is provided at the bottom of the main body 1;

[0043] A motor 2 is disposed on the top of the main body 1, and an output end of the motor 2 extends into the main body 1 and is fixedly connected to a first rotating shaft 3, and the bottom of the first rotating shaft 3 is rotatably connected to the bottom of the main body 1;

[0044] The upper end of the first rotating shaft 3 is fixedly connected to a material distribution ring 5 through a connecting rod 4. The annular surface of the material distribution ring 5 is arranged below the feed port 11. The material distribution ring 5 is provided with a plurality of material guide grooves 51, so that the raw materials can be drawn into the main body 1 along the material guide grooves 51.

[0045] A stirring mechanism 6 is slidably disposed at the lower end of the first rotating shaft 3;

[0046] The stirring mechanism 6 comprises a shaft sleeve 61, the shaft sleeve 61 is slidably sleeved on the first rotating shaft 3, and a plurality of stirring blades 63 are evenly arranged along the axial direction on the side of the shaft sleeve 61;

[0047] A support column 8 is provided at the bottom of the main body 1 .

[0048] After the raw materials enter the main body 1 from the feed inlet 11 , they are dispersed by the material distribution ring 5 and the material guide groove 51 , so that the raw materials fall evenly to the bottom of the main body 1 to avoid accumulation directly below the feed inlet 11 .

[0049] Preferably, a moving groove 31 is formed on the side surface of the lower end of the first rotating shaft, and a slider 62 is fixedly provided on the inner wall of the sleeve 61, and the slider 62 is slidably disposed in the moving groove 31;

[0050] An annular column 7 is fixedly disposed at the bottom of the main body 1. The annular column 7 is coaxially disposed with the first rotating shaft 3. The upper end surface of the annular column 7 is an inclined surface, and an annular groove 71 is formed on the upper end surface of the annular column 7.

[0051] An arc block 64 is fixedly provided on the lower end surface of the sleeve 61, and the arc block 64 is slidably set in the annular groove 71. The arc block 64 slides on the inclined surface of the annular column 7, so that the stirring mechanism 6 moves up and down along the moving groove 31 of the first rotating shaft 3 while rotating and stirring, so as to mix the raw materials evenly up and down.

[0052] Preferably, the cross section of the dividing ring 5 is conical and the top is arranged as an arc, so that the raw materials can slide along the two side surfaces of the dividing ring 5 to the bottom without causing the raw materials to accumulate on the top surface.

[0053] Preferably, both the inner and outer sides of the material distribution ring 5 are provided with material guide grooves 51 to facilitate better dispersion of the raw materials.

[0054] Preferably, the guide grooves 51 are of different sizes and are scattered on the side of the dividing ring 5. When the dividing ring 5 rotates, because the guide grooves 51 are of different sizes, the raw materials sliding down the guide grooves 51 take different times to slide down due to inertia, so the raw materials can be better dispersed.

[0055] Preferably, the material guide grooves 51 on both the inner and outer sides of the dividing ring 5 are both folded line grooves.

[0056] Preferably, the stirring blades 63 are distributed in a cross shape along the axis of the shaft sleeve 61 .

[0057] Preferably, the stirring blade 63 is propeller-shaped, which can generate thrust on the raw materials so that the upper layer and the lower layer of the raw materials are mixed evenly.

[0058] Preferably, four connecting rods 4 are provided and are distributed in a circular array around the axis of the first rotating shaft 3; the top of the connecting rod 4 is arc-shaped to avoid accumulation of raw materials.

[0059] The working principle of the utility model is as follows: the starting motor 2 rotates to drive the first rotating shaft 3 to rotate, and the rotation of the first rotating shaft 3 drives the dividing ring 5 to rotate, the raw material is put in from the feed port 11, and slides through the inclined side of the dividing ring 5, and the two side surfaces of the dividing ring 5 are provided with a broken line-shaped material guide groove 51, when the raw material falls into the upper part of the material guide groove 51, due to the inertia of the rotation of the dividing ring 5, the raw material will rotate with the material guide groove 51 and slide from the upper part of the material guide groove 51 through the corner to the lower part, and then fall into the bottom of the main body 1, because the material guide groove 51 is provided with different sizes, the raw material follows the different rotation angles due to inertia, thereby the raw material can be dispersed and fall into the inside of the main body 1, instead of piling up and falling below the feed port 11.

[0060] While the first rotating shaft 3 rotates, the stirring mechanism 6 arranged at the lower end of the first rotating shaft 3 rotates accordingly to stir the raw materials in time. Because the stirring blade 63 is propeller-shaped, it can generate thrust on the raw materials, so that the upper and lower layers of the raw materials are mixed evenly. The arc block 64 arranged on the lower end surface of the sleeve 61 slides in the annular groove 71. Because the upper end surface of the annular column 71 is an inclined surface, when the arc block 64 slides to the high point of the annular groove 71, the sleeve 61 moves upward on the movable groove 31 of the first rotating shaft 3 through the slider 62. When the arc block 64 slides from the high point to the low point of the annular groove 71, the sleeve 6 moves down vertically along the movable groove 31, thereby realizing that the sleeve 6 moves up and down while rotating, driving the stirring blade 63 to move up and down, and the raw materials are mixed and stirred more fully.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
