Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling devices, in particular to a rolling and stirring device. Background Art
[0002] Refractory materials refer to materials whose physical and chemical properties allow them to be used in high-temperature environments. They generally refer to inorganic non-metallic materials with a refractoriness of not less than 1,580 degrees Celsius. The refractoriness refers to the Celsius temperature at which a conical sample of a refractory material can resist high temperature without softening and melting under no load. Refractory materials need to be rolled and stirred during the production process, and the rolling process is often achieved through a rolling device.
[0003] During use of existing rolling devices, in order to improve the uniformity of rolling of refractory materials, a stirring rod is often used to stir the refractory materials. However, since the motion trajectory of the rolling roller is fixed, the refractory materials will deviate from the motion trajectory of the rolling roller after being rolled, resulting in reduced rolling efficiency and reduced rolling uniformity. In addition, some refractory materials will inevitably stick to the rolling roller during the rolling process, which will also reduce the rolling efficiency. Utility Model Content
[0004] In view of the shortcomings of the rolling device, the utility model provides a rolling and stirring device, which has the advantages of being able to sweep refractory materials into the motion trajectory of the rolling roller, preventing the refractory materials from adhering to the rolling roller, and improving the rolling effect. It solves the technical problems of refractory materials being squeezed away by the rolling roller and refractory materials adhering to the rolling roller.
[0005] The utility model provides the following technical solution: a rolling and stirring device, including a support frame, and also including:
[0006] A rolling cylinder is fixedly mounted on the top surface of the support frame, a sealing cover is hingedly connected to the top surface of the rolling cylinder through a hinge, a fixing rod is fixedly connected to the upper part of the side wall of the inner cavity of the rolling cylinder, one end of the fixing rod located in the middle of the rolling cylinder is fixedly connected to a mounting plate, and a motor is fixedly mounted in the middle of the top surface of the mounting plate;
[0007] A rotating shaft is fixedly connected to the output end of the motor, a turntable is fixedly sleeved on the outer surface of the bottom end of the rotating shaft, a transmission rod is fixedly connected to the bottom surface of the turntable, a rolling roller is movably sleeved on the outer surface of the transmission rod away from the turntable, and a stirring rod is fixedly connected to the outer surface of the bottom end of the rotating shaft.
[0008] Preferably, the stirring rod comprises:
[0009] The arc strip is fixedly connected to the end of the stirring rod away from the rotating shaft, the bottom surface of the arc strip is in sliding contact with the bottom surface of the inner cavity of the rolling cylinder, and the end of the arc strip away from the stirring rod is on the movement track of the rolling roller.
[0010] Preferably, the arc strip includes:
[0011] The blocking bar is fixedly connected to the middle part of the arc-shaped bar, and a closed circle is formed between the blocking bar and the arc-shaped bar.
[0012] Preferably, the transmission rod includes:
[0013] The fixing frame is fixedly connected to the outer surface of the transmission rod and is located on both sides of the rolling roller.
[0014] Preferably, the fixing frame includes:
[0015] The scraper is fixedly connected to the top of the fixing frame, and the bottom surface of the scraper is in sliding contact with the outer surface of the rolling roller.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. By designing arc bars and blocking bars, when the motor drives the rolling roller to roll the refractory material, the arc bars are driven to rotate through the stirring rod, so that the refractory material squeezed by the rolling roller will be scraped by the arc bars and return to the motion trajectory of the rolling roller, thereby improving the rolling effect. In addition, the blocking bar can effectively prevent the refractory material from moving to the middle of the rolling cylinder, so that the refractory material can always be on the motion trajectory of the rolling roller for rolling processing.
[0018] 2. By designing the fixed frame and scraper, since the rolling roller is in a rotating state inside the rolling cylinder, and the fixed frame is fixed on the transmission rod, the fixed frame is in a stationary state. At this time, as the rolling roller rotates, the refractory material adhered to the rolling roller will be scraped off by the scraper, and the refractory material scraped off by the scraper will fall back into the rolling cylinder for rolling, thereby improving the rolling efficiency.
