Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a material flattening structure of a boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler is in the form of chemical energy in the fuel, electrical energy, thermal energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] After searching, the existing Chinese patent with publication number CN202120413668.4 discloses a biomass fuel boiler feeding device that improves combustion efficiency. The biomass pellet fuel is stored in a storage tank with a discharge port at the bottom of the storage tank. The material leaving the storage tank falls onto a receiving plate. When the material is stored on the receiving plate, the moisture on its surface can be initially evaporated before entering the boiler through a bulk channel. The bulk channel can disperse the material, preventing the material from being concentrated in a certain position in the boiler, making it difficult for the material to fully contact the air, resulting in incomplete combustion of the material and reduced combustion efficiency.

[0004] The above technical solution has the following defects: although such a boiler feeding structure can evenly distribute the fuel through the distribution plate, the fuel is also distributed in strips when it is actually put into the boiler. In order to further improve the uniformity of the material feeding process, a material flattening structure of the boiler is proposed, which can feed the particle fuel more evenly, so that the material can be more fully in contact with the air, so that the material can burn more fully and improve the combustion efficiency.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0008] The solution of the utility model to solve the above technical problems is as follows: a material paving structure of a boiler, comprising a boiler body and a material conveying pipe, the outer wall of the boiler body is fixedly installed with a sealing frame and an adjusting frame, a sealing door is slidably connected in the sealing frame, the adjusting frame is fixedly connected with a brake stepping motor, the brake stepping motor is fixedly connected with a reciprocating screw, the outer wall of the reciprocating screw is threadedly connected with a screw nut, the screw nut is fixedly connected with a load-bearing slider, the adjusting frame is fixedly installed with a load-bearing rod, the top of the load-bearing slider is fixedly connected to the material conveying pipe, the inner wall of the material conveying pipe is fixedly installed with a rotating motor, the driving end of the rotating motor is fixedly connected with a feeding screw rod, the material conveying pipe is evenly fixedly connected with a material discharge pipe, the material conveying pipe is fixedly connected with a feed hopper, and the inner wall of the feed hopper is rotatably connected with a crushing roller.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the sealing door is provided with a slot corresponding to the material conveying pipe.

[0014] Furthermore, a hopper cover is placed on the top of the feed hopper.

[0015] Furthermore, two crushing rollers are provided, and both crushing rollers are fixedly connected to load-bearing gears, and the load-bearing gears on both sides are meshed and connected. The outer wall of the feed hopper is fixedly connected to a motor box, and the motor box is fixedly connected to a drive motor, and the drive end of the drive motor is fixedly connected to the crushing roller.

[0016] The utility model provides a material flat-laying structure for a boiler, which has the following advantages:

[0017] 1. Open the hopper cover and pass the pellet fuel into the feed hopper. Start the motor box to rotate the crushing roller on one side. The bearing gears of the crushing rollers on both sides are meshed and connected, so that the crushing rollers on both sides can rotate synchronously to crush the pellet fuel passing through, thereby preventing blockage when conveying materials;

[0018] 2. The crushed fuel pellets can be transferred to the material conveying pipe. The brake stepper motor in the adjustment frame is activated to rotate the reciprocating screw, which can drive the material conveying pipe to slide back and forth in the boiler body.
