Description

Rotor balance Technical Field The utility model relates to the technical field of rotor scales, in particular to a rotor scale. Background The rotor scale is an industrial equipment specially used for dynamic metering and continuous feeding control of powder materials, and is widely applied to industries such as cement, chemical industry, electric power, metallurgy and the like. The core design integrates the gravity calculation and balance balancing principles, and ensures high precision, stability and long-term reliability. The rotor scale solves the problems of jet flow, temperature change interference and the like in powder material metering by combining a balance structure with an intelligent control system, and becomes a key device for high-precision continuous feeding. The modularized design is suitable for severe industrial environments with high temperature and multiple dust, and is irreplaceable in scenes such as pulverized coal supply, chemical proportioning and the like of a cement kiln. In the prior art, a rotor scale mainly comprises a frame, a rotor scale shell, a feed inlet, a discharge outlet, a driving mechanism, a rotor assembly, a supporting mechanism and a weighing mechanism. The rotor assembly divides the rotor scale inner bin into a plurality of sub bins, powder enters the rotor sub bins through the feeding machine, evenly flows along with the rotation of the blades to a half circumference area, the weighing sensor detects the weight of materials in real time, the speed measuring sensor synchronously collects the rotating speed of the rotor, the control system synthesizes weight and speed signals, the instantaneous flow is calculated, and the rotating speed of the motor is regulated through the frequency converter, so that the closed-loop control of the flow is realized. Because the rotor scale has a relatively high precision requirement, the rotor scale needs to be periodically overhauled and maintained, for example, the rotor assembly is periodically checked, and the problem that the gap between the rotor scale and the rotor scale shell is increased due to serious blade abrasion, and the excessive gap can cause gas channeling to influence the measurement precision is solved. However, the shell of the rotor scale in the prior art is often an integral cylindrical shell, and then the top plate and the bottom plate are matched to form the inner bin of the rotor scale, when the rotor scale is overhauled, the top plate or the bottom plate is required to be disassembled, the rotor scale is reloaded after the overhauling is finished, the disassembly and assembly process is complicated, the overhauling speed of the rotor scale is influenced, and the overhauling efficiency of the rotor scale is lower. Disclosure of utility model Aiming at the problems, the utility model provides a rotor scale to solve the problems that in the prior art, the dismounting process of the rotor scale in the overhaul process is complicated, so that the overhaul efficiency of the rotor scale is low. The rotor balance is realized by the following technical scheme that the rotor balance comprises a top plate provided with a feed inlet and a bottom plate provided with a discharge outlet, a main shell is arranged between the top plate and the bottom plate, the top plate is arranged on a frame through a supporting mechanism, a weighing mechanism is arranged between the frame and the bottom plate, a rotor assembly which can be driven by a driving motor is arranged in the main shell, the main shell comprises a plurality of identical arc-shaped sub-shells, the head end and the tail end of the sub-shells are in butt joint to form a cylindrical main shell, the butt joint positions of the end faces of two adjacent sub-shells are in detachable fixed connection, and a hinge mechanism is arranged at the butt joint position of one part of the end faces. Through the structure, when the rotor balance is required to be overhauled, the fixed connection of the end-to-end joint of the partial shell can be relieved, the upper limit and the lower limit of the partial shell are relieved, the partial shell can be rotated through the hinge mechanism, the main shell can be opened to conveniently overhaul the rotor assembly inside the rotor balance through the opening, after the overhauling is finished, the opened partial shell is also required to be rotated back, and then the end-to-end joint and the top and the bottom are fixed again for use, so that the disassembly and assembly process in the overhauling process of the rotor balance is simpler and more convenient to use, and the overhauling efficiency of the rotor balance is improved. Preferably, the split shells are provided with four in total, two hinge mechanisms are provided, and the two hinge mechanisms are arranged at the joint at intervals. Through the setting of four sub-shells and the articulated mechanism that two intervals set up for every sub-shell can all be opened alone, and t
