Embodiment Construction

[0032] like figure 1 Shown is the dual hydraulic discharge port sealing device disclosed in the present invention, including the first hydraulic cylinder 10, the second hydraulic cylinder 11, the clamping plate 2, the insertion plate 3, the discharge port 40 and the plugging core 5;

[0033] like figure 2 and image 3 As shown, one end of the clamping plate 2 is connected to the first hydraulic cylinder 10, and one side of the clamping plate 2 is the first wedge surface 20;

[0034] like Figure 4 and Figure 5 As shown, one end of the flashboard 3 is a rotating end 30, and the other end is a driving end 31. The rotating end 30 is hinged at the discharge port 40, and the driving end 31 is connected to the second hydraulic cylinder 11. Hinged, one surface of the plug-in plate 3 is fixed with the plug core 5, and the other surface is a second wedge surface 33 that can be in contact with the first wedge surface 20;

[0035] like Figure 10 As shown, the discharge port 40 i...

Abstract

The invention discloses a double-hydraulic discharge port sealing device. The double-hydraulic discharge port sealing device comprises a first hydraulic cylinder, a second hydraulic cylinder, a jacking plate, an inserting plate, a discharge port and a plug core, wherein the jacking plate is connected with the first hydraulic cylinder; a first wedge surface is arranged on the jacking plate; one endof the inserting plate is hinged to the discharge port, and the other end of the inserting plate is driven by the second hydraulic cylinder; a second wedge surface is arranged on the inserting plate;the plug core is fixed on the inserting plate; the first hydraulic cylinder can drive the jacking plate to move; the second hydraulic cylinder can drive the inserting plate to rotate; when the firsthydraulic cylinder drives the jacking plate to move towards the driving end of the inserting plate, the first wedge surface can push the second wedge surface to contact the plug core on the insertingplate with the discharge port; and when the first hydraulic cylinder drives the jacking plate to move in the reverse direction, the jacking plate is separated from the inserting plate, and the secondhydraulic cylinder drives the inserting plate to rotate so as to open the discharge port. According to the double-hydraulic discharge port sealing device, larger sealing force on the discharge port can be obtained by applying smaller pushing force, the plug core and the discharge port are sealed in an inclined plane, and therefore, the sealing area is increased, so that the discharge port is better sealed.

Description

technical field [0001] The invention relates to the technical field of an internal mixer unloading device, in particular to a sealing device for a double hydraulic unloading port. Background technique [0002] In the internal mixer (or other equipment), it is usually necessary to add various raw materials in the internal mixing chamber (reaction chamber), and carry out extrusion or rolling processing with the added raw materials under a certain pressure and temperature. After the raw material is processed, the processed material is discharged through the discharge port for subsequent processing. During the processing of the material, the material generates a large pressure at the discharge port. [0003] The structure of the material door of the discharge port of the existing internal mixer is that one end is connected with the equipment through a pin shaft, and the other end is locked with a groove or a locking rod. The groove realizes the closure of the discharge port. Th...
