Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to an anti-blocking device for a rotary kiln feed port. Background Art

[0002] Rotary kiln is widely used in many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc. Rotary cylinder equipment is used to mechanically, physically or chemically treat solid materials. The main structure includes a kiln head part, a kiln body part and a kiln tail part. The kiln tail part is also an important part of the rotary kiln. The shape of the feed end is similar to the cover of a rotary bed kiln. It mainly undertakes the feeding and sealing functions. During the feeding process, the material is easy to block the feed port; the existing rotary kiln feed port has certain disadvantages when in use. When the material is put into the feed port, it is easy to stick to the inner wall of the feed barrel, thereby causing a waste of resources and difficult to clean. The residual material is easy to mix with other materials when used next time. When the material enters the inside of the kiln body, it is easy to cause blockage due to agglomeration, etc., affecting the subsequent work procedures. For this reason, we propose a rotary kiln feed port anti-blocking device. Utility Model Content

[0020] Reference Figure 1-5 , a rotary kiln feed port anti-blocking device, comprising a feed structure 1, a cleaning structure 2 is embedded and installed on the upper surface of the feed structure 1, and an anti-blocking structure 3 is fixedly installed on the lower surface of the feed structure 1;

[0021] The feeding structure 1 includes a hinge 101, a door panel 102, a first handle 103, a first conical bucket 104, a horizontal plate 105, a feeding barrel 106, a sleeve 107, and a sealing ring 108. The first conical bucket 104 is embedded and installed on the upper surface of the feeding barrel 106, the horizontal plate 105 is embedded and installed on the upper surface of the first conical bucket 104, the sleeve 107 is embedded and installed on the upper surface of the horizontal plate 105, and the sealing ring 108 is embedded and installed on the lower surface of the sleeve 107. The upper surface of the horizontal plate 105 is located at both sides and is movably connected to the door panel 102 through the hinge 101. The door panel 102 is divided into two groups, and the hinge 101 is divided into four groups. The first handle 103 is fixedly installed at the edge of the surface; the cleaning structure 2 includes a second handle 201, a connecting rod 202, a scraper 203, a triangular plate 204, and a connecting ring 205. The scraper 203 is fixedly installed on the upper surface of the connecting ring 205. The cross-section of the scraper 203 is triangular, and its outer surface is tightly attached to the inner surface of the feed barrel 106. The inner surface of the connecting ring 205 is embedded with a triangular plate 204. The triangular plate 204 is triangular, so that it is difficult for materials to fall on the triangular plate 204 and cause resource residue. The upper surface of the triangular plate 204 is fixedly installed with a connecting rod 202, and the upper surface of the connecting rod 202 is fixed. A second handle 201 is fixedly installed; the feeding structure 1 and the cleaning structure 2 are embedded and installed in the sealing ring 108 through a connecting rod 202, and the second handle 201 is located above the horizontal plate 105; the anti-blocking structure 3 includes a conveying frame 301, a second conical bucket 302, a discharge pipe 303, a driving motor 304, a screw rod 305, a rubber plate 306, a motor shaft 307, and a discharge port 308. The upper surface of the conveying frame 301 is embedded and installed with a discharge pipe 303 at one side, and the upper surface of the discharge pipe 303 is fixedly installed with a second conical bucket 302. A discharge port 308 is opened at the bottom of one side surface of the conveying frame 301. A motor shaft 307 is embedded in the other side surface of the frame 301, and a driving motor 304 is fixedly installed on one side surface of the motor shaft 307. The surface of the motor shaft 307 is located inside the conveying frame 301 and is sleeved with a screw rod 305. The surface of the screw rod 305 is sleeved with a rubber plate 306. The inner surface of the conveying frame 301 is cylindrical. When the screw rod 305 rotates, it can drive the rubber plate 306 to rotate, so that the rubber plate 306 is tightly attached to the inner surface of the conveying frame 301 to scrape the material on the inner surface of the conveying frame 301; the anti-blocking structure 3 is fixedly installed on the lower surface of the feed barrel 106 through the second conical bucket 302.

[0022] The implementation principle of the embodiment of the rotary kiln feed port anti-blocking device of the present application is as follows: when in use, the material enters through the feed structure 1, the anti-blocking structure 3 performs anti-blocking treatment, and the cleaning structure 2 cleans the inner wall of the feed structure 1. The user pinches the first handle 103, opens the door panel 102 through the hinge 101, and inputs the material into the feed barrel 106 through the first conical bucket 104. The material falls downward under the action of its own gravity and reaches the interior of the conveying frame 301 through the second conical bucket 302 and the discharge pipe 303. The drive motor 304 is started, and the drive motor 304 drives the electric motor 106 to rotate. The machine shaft 307 rotates, thereby conveying the material through the screw rod 305 and discharging it from the discharge port 308. At the same time, the rubber plate 306 continuously contacts the inner wall of the conveying frame 301 to clean the inner wall of the conveying frame 301 to prevent blockage. When the material is completely put into the first conical bucket 104, the second handle 201 is pinched and pulled up and down, so that the connecting rod 202 inside the sleeve 107 drives the triangular plate 204 to move up and down, so that the connecting ring 205 drives the scraper 203 to rub on the inner wall of the feed barrel 106, and then scrapes off the residual material on the feed barrel 106.
