Description

A boiler coal feeding device Technical Field

[0001] The invention relates to the field of boiler coal delivery, in particular to a boiler coal delivery device. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. Most existing boilers generate heat by burning coal, which has many advantages. First, coal can provide efficient heating and hot water supply because coal is a fuel with high calorific value. Second, coal is relatively cheap, which can reduce energy costs. In addition, the supply of coal is relatively stable and not easily affected by weather or political factors, so it has high stability. In addition, coal boilers usually have a long service life and stable performance, and can provide continuous heating and hot water supply. Through advanced technology, coal boilers can reduce emissions and improve energy utilization efficiency, thereby reducing the impact on the environment.

[0003] In actual use, large coal-fired boilers are extremely high, reaching more than ten meters. It is very risky for operators to climb up directly with ladders. In large coal-fired boilers, since the coal stacking height changes over time, large coal-fired boilers are usually connected to multiple coal inlet pipes to adapt to the coal stacking height. When the coal in the raw coal bin is transported to each coal inlet pipe through a diverter device, the diverter device often has to withstand the impact of the coal and is easily damaged.

[0052] In this embodiment, when the operator needs the coal to fall out of the second branch pipe 201c, the branch pipe 203 is vertically facing the second branch pipe 201c, and the coal can fall vertically from the second branch pipe 201c; because the branch pipe 203 is in a vertical state, the branch pipe 203 does not need to bear the impact of the coal when it falls from the coal collecting pipe 202 into the branch pipe 203. At this time, the operator only needs to keep the drive assembly 301 stationary.

[0053] It should be noted that when the operator needs to fix the ladder, he can push the bottom of the ladder and squeeze the bevel on the fastening part 102c-4a to retract the fastening part 102c-4a into the fastening seat 102c-2. When the hanging ladder is completely pushed between the fastening seat 102c-2 and the support seat 102c-3, the fastening part 102c-4a extends under the elastic force of the fastening spring 102c-5 to fix the bottom of the ladder. When the operator needs the coal to fall out of the first branch pipe 201b, he must first control the drive motor 301a to make the telescopic rod 3 01b contracts, the contracted telescopic rod 301b will pull the hinge seat 301c. When the hinge seat 301c is pulled, the movable block 301c-3 will be pulled from the middle state of the movable cavity W-4 as shown in Figure 11 to the edge of the movable cavity W-4. At the same time, the second slider 301d-1 is squeezed out of the fourth slide hole W-7 by the first slider 301c-2 and is completely squeezed into the second slide hole W-5. When the branch pipe 203 is pulled to face the first branch pipe 201b, the first locking part 302b-2 will be pushed to the first lock part 302b-2. At the end of a lock hole W-2, during this process, the first locking portion 302b-2 will squeeze the rounded portion of the first locking block 201a-2, pressing the first locking block 201a-2 into the first lock seat 201a-1. When the second lock hole K-2 is facing the first locking block 201a-2, the first locking block 201a-2 will rebound into the second lock hole K-2 under the elastic force of the first spring 201a-3, completing the locking of the first locking portion 302b-2; after the first locking block 201a-2 rebounds into the second lock hole K-2, the end of the first locking block 201a-2 The first unlocking block 302b-4 will be squeezed, and the first unlocking block 302b-4 will squeeze the second unlocking block 302c-1 out of the pressure hole K-3. The third unlocking block 302c-2 will squeeze the pressure plate 301d-4 at the same time, and then squeeze the end of the locking rod 301d-3 into the second sliding hole W-5 under the second slider 301d-1; after that, the impact of the falling coal borne by the branch pipe 203 will be absorbed by the first lock seat 201a-1 through the first locking part 302b-2, and the impact on the drive motor 301a will be greatly reduced.

[0054] It should also be noted that, after the coal has fallen from the first branch pipe 201b, the operator only needs to control the drive motor 301a to extend the telescopic rod 301b to unlock the branch pipe 203; during this process, the telescopic rod 301b will push the hinge seat 301c, and when the hinge seat 301c is pushed, the movable block 301c-3 will be pushed back from the state of contacting the edge of the movable cavity W-4 to the state shown in Figure 11. At this time, the fourth sliding hole W-7 is again facing the second sliding hole W-5, and the second slider 301d-1 will also be pushed into the fourth sliding hole W-7 under the elastic force of the second spring 301d-2; in the process of the second slider 301d-1 being pushed, the second slider 301d-1 will press the locking rod 301d-3 out of the second sliding hole W-5, and the sliding locking rod 301d-3 will push the third unlocking block 302c-2 through the pressure plate 301d-4, and then the third unlocking block 302c-2 will push the second unlocking block 302c-1 into the pressure hole K-3. The second unlocking block 302c-1 pressed into the pressure hole K-3 will push the first unlocking block 302b-4 to squeeze the first locking block 201a-2, and press the first locking block 201a-2 out of the second lock hole K-2; after this, the branch pipe 203 is unlocked, and the operator can control the branch pipe 203 to turn to the second branch pipe 201c or the third branch pipe 201d.

[0055] It should be understood that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.
