Numerical control boiler with fuel screening mechanism

[0011] In order to make the objectives, technical solutions, and beneficial effects of the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and not used to limit the protection scope of the present invention.

[0012] Such as figure 1 , figure 2 As shown, in order to achieve the purpose of the present invention, the present invention provides a numerically controlled boiler with a fuel screening mechanism. The numerically controlled boiler includes a shell, a water jacket, a combustion chamber, a heat exchange chamber, and an induced draft fan. The water jacket is The cavity is fixedly connected to the outer shell, and the inner cavity is provided with the combustion chamber and the heat exchange chamber, the combustion chamber and the heat exchange chamber are in communication, the induced draft fan is fixedly connected to the shell, and is connected to the The heat exchange chamber is in communication, the shell is provided with a coal charging port, a slag removal port and a carbon removal port, the coal charging port is fixedly connected with a storage box, and the coal charging port is connected to one side of the storage box In communication, the other side of the storage box is connected with a pushing mechanism, the pushing mechanism includes a cylinder, a pushing controller, and a pushing block, the pushing block is arranged inside the storage box, It is fixedly connected with the push rod of the air cylinder, and moves left and right inside the storage box under the drive of the air cylinder. The air cylinder is connected with the pushing controller, and the inner bottom surface of the storage box is provided There is an electronic scale, the push block slides on the electronic scale, a feeding mechanism is arranged above the storage box, and the feeding mechanism includes a transmission belt and a screening mechanism. One end of the transmission belt is grounded, and the other end is arranged at Above the storage box, the screening mechanism includes a screening frame and an air cylinder, the screening frame is arranged above the conveyor belt, the air cylinder is arranged immediately in front of the screening frame, and the screen frame is arranged There is a contact sensor, and both the contact sensor and the cylinder are connected with a screening controller.

[0013] Compared with the prior art, the present invention is equipped with a screening mechanism. When the shape of the fuel is too large, the cylinder receives a signal and pushes the fuel with the excessive shape down the conveyor belt, so that the automatic filling work can proceed smoothly. At the same time, the timing is set. The feeding mechanism reduces the manual participation of operators, reduces labor intensity, and ensures the effectiveness of filling.

[0014] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also It should be regarded as the protection scope of the present invention.
