Embodiment 1

[0032] This embodiment is basically as figure 1 and figure 2 Shown: The double-rotor continuous extrusion desulfurization rubber powder production device includes a driving motor 1, a material barrel 2, a first screw 3 and a second screw 4, and the output end of the driving motor 1 is coaxially fixedly connected with a rotating shaft 5. The right end is connected with the first screw rod 3 through a coupling. The first screw 3 and the second screw 4 are driven by a transmission belt 6 .

[0033] The first screw 3 is integrally formed with a forward helical blade a7 and a reverse helical blade a8, the outer diameter of the reverse helical blade a8 is smaller than the outer diameter of the forward helical blade a7, and the length of the reverse helical blade a8 is shorter than that of the forward helical blade. The length of blade a7. The second screw 4 is provided with a forward helical blade b9 , and the forward helical blade a7 and the reverse helical blade a8 on the firs...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that: image 3 and Figure 4 As shown, the second screw rod 4 is provided with a reverse helical blade b28, the outer diameter of the reverse helical blade b28 is smaller than the outer diameter of the forward helical blade b9, and the length of the reverse helical blade b28 is equal to the length of the reverse helical blade a8, The reverse helical blade b28 is arranged opposite to the reverse helical blade a8 and forms a reverse group. There are at least two groups of reverse groups, one of which is located in the barrel 2 of the cooling section, and the remaining groups are located in the barrel 2 of the heat preservation section 16 . In this embodiment, the number of reverse groups is two groups.

[0043] In this embodiment, when the rubber powder moves to the right in the reverse group of the insulation section 16, the reverse helical blade b28 and the reverse helical blade a8 exert leftward thrust on the...

Embodiment 3

[0046] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, both sides of the reverse helical blade a8 are provided with a number of grooves a29 along its radial direction, and both sides of the reverse helical blade b28 are provided with a number of grooves b30 along its radial direction. In this embodiment, the distance between two adjacent grooves a29 is 20 mm, and the distance between two adjacent grooves b30 is 20 mm.

[0047] In this embodiment, several grooves a29 are provided in the radial direction of the reverse spiral blade a8, so the surface of the reverse spiral blade a8 is uneven. Similarly, a number of grooves b30 are provided in the radial direction of the reverse spiral blade b28. The surface of the helical blade b28 is uneven. With the rotation of the first screw 3 and the second screw 4, the reverse helical blade a8 and the reverse helical blade b28 push the rubber powder to move to the left. During the process, the rotation ...

Abstract

The invention relates to the technical field of rubber production equipment, and specifically discloses a double-rotor continuous extrusion desulfurization rubber powder production device, including a driving motor, a barrel, a first screw and a second screw, and the rotation direction of the first screw and the second screw Similarly, the first screw rod is provided with a forward helical blade a and a reverse helical blade a, the outer diameter of the reverse helical blade a is smaller than the outer diameter of the forward helical blade a, and the second screw rod is provided with a forward helical blade b; One end of the barrel is connected with a feed pipe, and the other end of the barrel is connected with a discharge pipe. The barrel is divided into a heating section, a heat preservation section and a cooling section along the axial direction. In the present invention, the reverse helical blade a is used to push the material in the barrel to move in the reverse direction, while the forward helical blade a and the forward helical blade b push the material in the barrel to move forward, forcing the material to move forward as a whole. The material in the middle is squeezed in the axial direction to make it more compact, thus improving the compactness of the material after discharge.

Description

technical field [0001] The invention relates to the technical field of rubber production equipment, and specifically discloses a double-rotor continuous extrusion desulfurization rubber powder production device. Background technique [0002] The screw machine is the core of the polymer material transportation equipment commonly used at present. The rotor element in the screw machine is a thread-shaped conveying element. When the rotor element rotates, the material is automatically conveyed under the action of dragging. According to the number of screws, screw machinery can be divided into single-screw and twin-screw, among which, twin-screw has better mixing and exhaust functions than single-screw. Therefore, in the production process of rubber powder, a twin-screw extruder more suitable for powder processing is usually used for reaction and conveying. In the existing twin-screw extruder, the twin-screws mesh with each other and rotate in the same direction or reversely to ...
