Technical Field

[0001] The utility model relates to a release agent adding device, belonging to the technical field of adding devices. Background Art

[0002] In the process of producing epoxy asphalt, in order to achieve the modification of rubber raw materials, the rubber raw materials need to be crushed into rubber powder. However, since rubber has strong viscosity, the viscosity of rubber powder is even greater. In order to prevent the rubber powder from sticking together, an isolation agent needs to be added. However, some block isolation agents are mixed in the isolation agent. At present, in the production workshop, the isolation agent is manually weighed and put into the hopper. The isolation agent is mixed with the rubber powder through the pipeline. The problems of manual addition are: first, the block isolation agent cannot be fully crushed, and second, the manual weighing error is large.

[0003] Chinese patent (CN216368200U) discloses an automatic release agent adding device, including a horizontally arranged feeding barrel, a crushing feed box and a release agent silo are arranged above the feeding barrel in sequence, a feeding screw is passed through the inside of the feeding barrel, the shaft heads at both ends of the feeding screw are rotatably connected to the feeding barrel, a plurality of guide rods are arranged in the middle of the feeding screw, a first feeding screw is arranged on the outer wall of one end of the feeding screw, a second feeding screw is arranged on the outer wall of the other end of the feeding screw, and the spiral direction of the second feeding screw is opposite to that of the first feeding screw; guide pipes are respectively installed below the two ends of the feeding barrel, and the two guide pipes are symmetrically arranged; there are two crushing feed shafts rotating in opposite directions inside the crushing feed box. The automatic release agent adding device provided by the utility model can deliver release agents with uniform particle size to two dryers in a timely and quantitative manner, and can also ensure the accuracy of the release agent delivery amount.

[0004] The problem with the above patent is that the release agent will adhere to the feeding screw during the addition process, resulting in waste of the release agent and reducing the actual amount of release agent added, affecting the effect. Utility Model Content

[0008] The two screws have the same thread rotation direction, and the two screws are arranged to rotate in a direction close to each other. While the two screws fully crush the release agent, the two screws can clean the release agent remaining on the surface of each other to prevent the release agent from adhering to the screws, thereby ensuring the accuracy of the release agent delivery amount.

[0009] The stirring assembly includes a plurality of stirring plates, which are placed in the stirrer and connected to the transmission assembly through a stirring shaft. The stirring plates stir the release agent in the stirrer, so that the granular release agent collides with each other and is refined.

The bottom of the stirrer is provided with a movable gasket corresponding to the dosing mechanism. The dosing mechanism can accurately measure the weight of the release agent in the stirrer. When the weight of the release agent reaches a preset value, the gasket at the bottom of the stirrer opens to achieve quantitative delivery of the release agent.

[0012] The dosage mechanism is an electronic dosage valve. The electronic dosage valve is an electronic device with more accurate weighing precision.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model realizes automatic addition of the release agent and crushing of the release agent through a stirring component, a weighing component, a conveying component and a transmission component, thereby ensuring the accuracy of the release agent delivery amount.

[0015] (2) The stirring assembly includes a plurality of stirring plates, which are placed in the stirrer and connected to the transmission assembly through a stirring shaft. The stirring plates stir the release agent in the stirrer, causing the granular release agent to collide with each other and be refined.
