Description

Technical Field

[0001] The utility model belongs to the field of rotor scale equipment, in particular to a rotor scale with material accumulation prevention function. Background Art

[0002] The cement rotor scale is a device used to accurately measure and continuously transport materials during cement production. The current cement powder quantitative loading device has significant shortcomings. Due to the lack of a material accumulation prevention structure, it is very easy to have problems such as material blocking the channel, inaccurate metering, and material residue in actual operation. These shortcomings are mainly due to the characteristics of the cement powder itself. Its small particle size and certain viscosity make it easy to adhere to the inner wall of the device and the surface of components during transportation and loading. Conventional methods to deal with such problems include increasing the air purge force and increasing the conveying speed. However, although increasing the air purge force can reduce material adhesion to a certain extent, it may cause the material to fly, causing environmental pollution and material loss, while increasing energy consumption and equipment operating costs. Although increasing the conveying speed helps to reduce the residence time of the material in the device and reduce the risk of accumulation, it will bring many disadvantages. High-speed transportation can easily cause severe friction between materials and between materials and device components, which may cause the material to heat up, affect its physical and chemical properties, and thus affect the quality of cement. In addition, too fast a conveying speed will increase the wear of the equipment, shorten the service life of the equipment, increase the frequency and cost of maintenance, and cannot fundamentally solve the problems of material blockage and residue, which will still have an adverse effect on the efficiency and accuracy of loading. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

A vibration motor 211 is installed on the outer surface of the feed pipe 1 210. A mounting frame 240 is installed inside the feed barrel 230. A conveying auger 260 is installed on the lower surface of the mounting frame 240 through a rotating motor 250. A discharge pipe is installed at the discharge port on the lower surface of the rotor scale body 100. A stirring motor 310 is installed on the outer surface of the discharge pipe, and a stirring rod 311 is installed on the output shaft of the stirring motor 310 through a coupling.

[0021] See also Figures 1 to 3 As the first embodiment of the utility model: the rotor scale body 100 is a cylindrical structure, a feed pipe 210 is sealed and installed at the feed port on the upper side surface of the rotor scale body 100, the diameter of the feed port is the same as the inner diameter of the feed pipe 210, and two vibration motors 211 are symmetrically installed on the outer surface of the feed pipe 210;

[0022] The upper surface of the feed pipe 1 210 is sealedly connected to the feed pipe 2 220. The diameter of the feed pipe 1 210 is the same as that of the feed pipe 2 220. The end of the feed pipe 220 away from the feed pipe 1 210 is integrally formed with a feed barrel 230. The cross section of the feed barrel 230 is an inverted isosceles trapezoidal structure, and the upper surface of the feed barrel 230 is open.

[0023] A mounting frame 240 is installed at the center of the upper surface of the feed barrel 230, and both ends of the mounting frame 240 are connected to the inner wall of the feed barrel 230. An auger motor is installed at the center of the upper surface of the mounting frame 240, and the output shaft of the auger motor passes through the surface of the mounting frame 240;

[0024] A conveying auger 260 is installed on the lower surface of the mounting frame 240 through the rotation of the auger motor, and the outer surface of the conveying auger 260 abuts against the inner wall of the feed pipe 1 210 and the feed pipe 2 220;

[0025] When in use, the rotor scale body 100 is a prior art, and its specific working principle and structure are not described in detail here. Its model can be selected from the existing market models, as long as it meets the needs of the equipment. When cement is used through the rotor scale body 100, the cement powder will first be transported to the inside of the feed pipe 220 through the opening on the upper surface of the feed barrel 230. Then, when adding cement powder, the user first starts the rotating motor 250 on the upper surface of the mounting frame 240 and the vibrating motor 211 on the outer surface of the feed pipe 1 210, so that the feed pipe 1 210 and the feed pipe 2 The conveying auger 260 inside 220 rotates, thereby conveying the cement powder entering the inside of the feed pipe 220 to the inside of the rotor scale body 100 for operation. Since the conveying auger 260 can stably convey materials under the drive of the rotating motor 250, it helps to achieve uniform feeding, so that the cement material can enter the rotor scale at a relatively stable and consistent speed, thereby improving the accuracy of measurement. At the same time, the vibration motor 211 of the conveying auger 260 can make the feed pipe 1 210 vibrate, which helps to avoid blockage and accumulation of materials in the feed pipe 1 210, and promotes its smooth falling.

[0027] During use, when the cement powder is weighed inside the rotor scale body 100, it will be discharged from the discharge port of the rotor scale body 100. At this time, the user can start the stirring motor 310 on the outer surface of the discharge pipe to make the conveying shaft of the stirring motor 310 drive the stirring rod 311 to rotate. At this time, the rotating stirring rod 311 will rotate inside the discharge pipe (the horizontal stirring rod 311 will not block the discharge of materials due to its rotation. On the contrary, the rotating stirring rod 311 will make the discharge of materials smoother). Therefore, the rotation of the stirring rod 311 can effectively avoid the accumulation and agglomeration of materials in the discharge pipe, thereby preventing the discharge from being blocked and ensuring the smoothness of the discharge.
