Numerical control boiler with fuel screening mechanism

Abstract

The invention discloses a numerical control boiler with a fuel screening mechanism. A coal adding opening is fixedly connected with a material storage box and communicated with one side of the material storage box. The other side of the material storage box is connected with a pushing mechanism. The pushing mechanism comprises an air cylinder, a pushing controller and a pushing block, and the pushing block is arranged in the material storage box and fixedly connected with a pushing rod of the air cylinder. The screening mechanism comprises a screening frame and an air cylinder. The screening frame is arranged above a conveying belt, the air cylinder is arranged close to the front portion of the screening frame, a contact sensor is arranged on the screening frame, and the contact sensor and the air cylinder are both connected with a screening controller. The numerical control boiler is provided with the screening mechanism, and when the dimension of fuel is too large, the air cylinders receive signals, and the fuel with the too large dimension is pushed down off the conveying belt, so that automatic filling work can be performed smoothly. Meanwhile, a timing feeding mechanism is arranged, the effectiveness of filling is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of boiler manufacturing, in particular to a numerically controlled boiler with a fuel screening mechanism. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . Numerical control technology is a technology that uses digital information to control mechanical movement and working process. Numerical control equipment is a mechatronic product formed by the penetration of new technologies represented by numerical control technology into traditional manufacturing industries and emerging manufacturing industries, so-called digital equipment , such as CNC machine tools, etc. Numerical control boilers refer to boilers that use digit...

Problems solved by technology

[0005] The purpose of the present invention is to provide a numerically controlled boiler with a fuel screening mechanism to solve the problem in the prior art that when the numerically controlled boiler is running for a long time, the operator needs to frequently add fuel to the numerically controlled boiler. If the shape is too large, it will block the coal filling port, thereby affecting the efficiency of fueling, increasing the labor intensity and complexity of the operator, and causing adverse effects on production and life.
