Description

Technical Field

[0001] The utility model relates to the technical field of material discharge devices, in particular to a material discharge device for a rotary kiln. Background Art

[0002] A rotary kiln is a rotary calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the materials they process. When unloading materials, a unloading device is needed to ensure smooth unloading.

[0003] Publication No. CN206891153U discloses a rotary kiln sintered nickel ore powder rotary feeding device, comprising a feeding chamber, a conical feeding hopper is arranged below the feeding chamber, and the feeding chamber is connected with the conical feeding hopper, support frames are arranged on both sides of the feeding chamber, a feeding channel is arranged at one end of the conical feeding hopper away from the feeding chamber, a driving motor is installed at the center of one end of the feeding chamber away from the conical feeding hopper, the output shaft of the driving motor extends to the inside of the feeding chamber through a bearing, and is connected with a rotating shaft, a spiral feeding paddle is arranged on the rotating shaft, two groups of support rods are arranged from top to bottom on the rotating shaft, one end of the support rod away from the rotating shaft is movably sleeved in a telescopic rod, the telescopic rod is a hollow structure, and one end connected to the support rod is provided with an opening, a telescopic spring is arranged in the telescopic rod, the telescopic spring is connected to the support rod, one end of the telescopic rod away from the support rod is fixedly connected with a scraper rod, the scraper rod is arranged close to the inner wall of the feeding chamber, and a feeding port is arranged at the top of the feeding chamber. This type of unloading device not only increases the unloading speed, but also scrapes off the nickel ore powder attached to the inner wall to avoid the waste of raw materials. However, when the unloading chamber is congested, this type of unloading device needs to rely on manual knocking or other manual methods to clear it. This method not only requires the operator to monitor the operating status of the equipment at all times, but also requires immediate manual intervention measures once a blockage is found. Manual knocking is not only time-consuming and labor-intensive, but also has limited unblocking effects and cannot completely solve the problem of material accumulation. Therefore, improvements are needed. Utility Model Content
