Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary kilns, in particular to a kiln head cyclone sealing device. Background Art
[0002] A rotary kiln is used when firing cement. A kiln head hood is installed on the outside of the kiln head of the rotary kiln. During production operation, the kiln head hood gathers the clinker temperature to prevent the clinker from overflowing. Under the action of the exhaust fan, the hot air drawn from the cooler is sent into the kiln through the kiln head hood, so as to make full use of waste heat and reduce heat consumption.
[0003] The kiln head sealing ring will be worn out after long-term use, resulting in the problem that the sealing ring is not firmly sealed to the kiln head. After the kiln head is under negative pressure, the internal pressure-depleted material becomes cyclone-shaped, resulting in serious sand and material spraying at the kiln head and heavy dust. For this reason, we propose a kiln head cyclone sealing device to solve the existing problem. Utility Model Content
[0004] The utility model aims to solve the problems existing in the background technology and proposes a kiln head cyclone sealing device.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kiln head cyclone sealing device, comprising a kiln head, a sealing cover, a sealing hood and a supporting ring plate, wherein an opening is arranged at one end of the kiln head, a supporting ring plate is arranged inside the opening, a sealing cover is arranged at one end of the kiln head, a mounting ring groove is arranged inside one end of the sealing cover, a sealing ring is arranged between the supporting ring plate and the sealing cover, a sealing hood is arranged at one end of the kiln head, and a pressure sensor is embedded and installed inside the upper end of the sealing hood.
[0006] When using a kiln head cyclone sealing device in the present solution, the sealing ring is installed inside the installation ring groove, the sealing plate is rotated and closed on the supporting ring plate through a hinge, the sealing ring is squeezed into the extrusion ring groove, the sealing cover is connected to the docking ring groove, the docking plates are docked, the bolts are rotated and inserted into the docking plate to squeeze the sealing gasket, and the pressure sensor monitors the internal pressure of the sealing cover. If the pressure at one end is abnormal, a signal is sent out in time to alert the terminal personnel, and the leaked material at the closing point of the sealing cover and the kiln head is intercepted.
[0007] Preferably, a hinge is rotatably installed between the sealing cover and the kiln head. The sealing cover rotates at one end of the kiln head through the hinge.
[0008] Preferably, one end of the sealing ring is located inside the mounting ring groove, and an extrusion ring groove is provided inside one end of the supporting ring plate, and the extrusion ring groove corresponds to the sealing ring. The sealing ring is installed inside the supporting ring plate, and is a sealing component that closes the sealing cover and the kiln head opening, thereby increasing the sealing between the sealing cover and the opening.
[0009] Preferably, the kiln head and the outer wall of the sealing cover are both provided with a docking plate, and bolts are rotatably inserted inside the docking plate. The kiln head is docked with the sealing cover through the connecting plate, and the bolts are fixed to the docking plate.
[0010] Preferably, a butt joint groove is provided inside one end of the kiln head, one end of the sealing cover is located inside the butt joint groove, and a sealing gasket is provided on the inner wall of the butt joint groove. When one end of the sealing cover is pressed and fixed, the sealing gasket is pressed, and the sealing gasket shrinks and fills the joint between the sealing cover and the butt joint groove, so that the inside of the sealing cover is sealed.
[0011] Preferably, the inner wall of the sealing cover is provided with equidistantly distributed pressing plates, which press the sealing plate after the sealing cover is fixed, and the sealing plate is pressed and fixed by the pressing plates.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model provides a sealing cover on the outside of the sealing cover, and the sealing cover performs secondary sealing on the sealing cover and the outside of the kiln head. When the seal between the kiln head and the sealing cover is damaged and the seal is not firm, the sealing cover still seals the kiln head, thereby preventing the pressure inside the kiln head from changing, thereby causing serious sand and material spraying and large dust problems;
[0014] 2. By setting an extrusion ring groove at the joint between the sealing cover and the kiln head, the inner wall of the extrusion ring groove is smaller than the specification of the sealing ring, the sealing ring is tightly squeezed, and the fit between the sealing ring and the kiln head is increased.

An opening 8 is provided at one end of the kiln head 1, and a supporting ring plate 7 is provided inside the opening 8. A sealing cover 2 is provided at one end of the kiln head 1, and a hinge 12 is rotatably installed between the sealing cover 2 and the kiln head 1. A mounting ring groove 11 is provided inside one end of the sealing cover 2, and a sealing ring 10 is provided between the supporting ring plate 7 and the sealing cover 2. One end of the sealing ring 10 is located inside the mounting ring groove 11, and an extrusion ring groove 9 is provided inside one end of the supporting ring plate 7, and the extrusion ring groove 9 corresponds to the sealing ring 10.
[0022] Based on the implementation steps of Example 1: the opening 8 is the inspection port of the kiln head 1, and a sealing ring 10 is arranged inside one end of the sealing cover 2 relative to the supporting ring plate 7, and when the sealing ring 10 is squeezed into the extrusion ring groove 9, the sealing ring 10 behaves as one end of the extrusion ring groove 9 is pressurized and contracted by the sealing cover 2, while the side outer wall is pressurized by the side inner wall of the extrusion ring groove 9, and is squeezed by the lateral and longitudinal forces at the same time, so that the sealing ring 10 and the supporting ring plate 7 fit more firmly.
