Problems solved by technology

However, the amount of materials to be burned is often different due to changes in the demand for heat energy. Therefore, the height of the stacked materials is often not enough to achieve the effect of blocking high-temperature smoke, resulting in the disadvantages of easy damage to the material pulling device and short service life.

Embodiment 1

[0019] See figure 1 , figure 2 A preferred embodiment of the material shifting control device of the present invention is applied to a burner 1. The burner 1 has an internal combustion furnace 11 that burns materials 10 to generate heat, a material shifting device 12 installed in the internal combustion furnace 11, and a material supply device 13 that conveys the material 10 into the internal combustion furnace 11. The internal combustion furnace 11 has a furnace wall 111 surrounding the axis, and a carrying plate 114 that is blocked on the inner surface of the furnace wall 11 and is formed with a combustion space 112 and an ash discharge space 113. The carrying board 114 is used to carry the material 10. The material shifting device 12 has a motor 121 disposed under the internal combustion furnace 11, a rotating shaft 122 coaxial with the motor 121 and penetrating the carrier plate 114, and a material shifting rod 123 fixed to the rotating shaft 122 and located on the carrier...

Embodiment 2

[0038] The same as the first embodiment, the difference is that this embodiment further includes the following steps:

[0039] Step 79: The first temperature sensor 41 senses the combustion temperature of the inner layer of the material 10 and sends it back to the central control module 5;

[0040] Step 80: The central control module 5 compares whether the combustion temperature of step 79 is higher than the preset value of the combustion temperature. If it is, it means that the combustion temperature of the inner layer of the material 10 is too high, and the combustion rate must be reduced, proceed to step 81, if If no, go to step 82.

[0041] Step 81: The central control module 5 controls the shift lever 123 through the motor 121 to be less than the initial speed V 0 The second speed V 2 Rotate a predetermined rotation time t 2 Then go back to step 73;

[0042] Step 82: The second temperature sensor 42 senses the ash temperature in the ash discharge space 113, and transmits it back ...

Abstract

The invention relates to a stirring detection and control method and a stirring control device for a burner. The stirring control device comprises an upper detector and a lower detector that are arranged at an internal combustion furnace, as well as a central control module connected and communicated with the upper detector and the lower detector. The upper detector and the lower detector detect material height, and the central control module controls a stirring rod to rotate at a first rotating speed higher than the initial rotating speed when the material height reaches the upper detection limit of the upper detector, and gives an abnormal alarm when the material height does not reach the lower detection limit of the lower detector. The rotating speed of the stirring rod can be determined and the material height in the internal combustion furnace can be maintained intelligently, so that a material at appropriate height can effectively divide a combustion space above the material and an ash discharge space below the material, and the service lives of related components in the ash discharge space are prolonged.

Description

Technical field [0001] The invention relates to a combustor, in particular to a material shifting control method and device of a combustor that generates heat energy from burning materials. Background technique [0002] Generally, the residual materials after grains are not edible, but they can produce a usable heat source after combustion, which achieves the effect of resource recovery and energy reuse, and has considerable utilization value. Therefore, the patent publication No. M304628 "Burner" and the patent No. M304629 "Burner with air duct system" that the applicant previously applied for and were approved in this case are mainly the use of burning materials. Generate usable heat sources to facilitate resource recovery and energy reuse. [0003] After the materials are shelled and burned, high-temperature flue gas of nearly a thousand degrees or more, a large amount of smoke and dust, and a large amount of residual ash will be generated. Therefore, in order to avoid the ash ...
