[0002] Currently, in most thermal power plants, coal is generally used as the raw material for power generation. The slag formed after the coal enters the boiler and burns needs to be transported, crushed by the slag removal system, and finally enters the slag yard.

[0003] The slag falls on the conveyor belt of the dry slag discharger and is slowly transported to the crushing part by the conveyor belt. However, there is a gap between the conveyor belt and the side wall of the slag discharger, and the finer slag often falls through the gap to the bottom of the slag discharger.

[0004] In order to remove the fallen fine slag, a cleaning chain that moves cyclically is usually used to drive a scraper to scrape the slag to the crushing part. However, the fine slag has fluidity and is prone to accumulate fine slag at the slope position of the dry slag discharger, which may lead to derailment and deformation of the cleaning chain, and the slag removal system has to be shut down for maintenance.

[0005] To avoid this accident, the accident slag discharge door at the slope of the slag discharger is usually kept open for a long time, and the slag accumulated at the slope is discharged through the accident slag discharge door, which will cause problems such as more dust in the flue gas, serious wear of the boiler heating surface, and air leakage at the bottom of the boiler body.

[0039] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0041] Embodiment 1

[0042] Referring to Figures 1 to 3 , which is the first embodiment of the present invention. This embodiment provides a fine slag discharge mechanism, including a mounting component 100, a slag discharge component 200, and a slag cleaning component 300. The slag discharge component 200 and the slag cleaning component 300 are adaptively installed outside the mounting component 100;

[0043] Among them, the slag discharge component 200 and the slag cleaning component 300 are used for automatic slag discharge.

[0044] Specifically, the mounting component 100 includes a screening component 101, a guiding component 102 adaptively installed outside the screening component 101, and a collecting component 103 adaptively installed outside the guiding component 102;

[0045] Among them, the screening component 101 is used to screen out fine furnace slag, and the fine furnace slag enters the inside of the collecting component 103 through the guiding component 102.

[0046] Furthermore, the screening component 101 includes a mounting plate 101a and a sieve plate 101b fixedly connected to the outside of the mounting plate 101a;

[0047] The guiding component 102 includes a connecting frame 102a bolted to the outside of the mounting plate 101a and a funnel 102b fixedly connected to the outside of the connecting frame 102a;

[0048] The collecting component 103 includes an ash baffle 103a fixedly connected to the outside of the funnel 102b and a collecting cylinder 103b fixedly connected to the bottom end of the ash baffle 103a.

[0049] During use, the mounting plate 101a is mounted on the outside of the dry slag discharger through bolts, and the specific mounting position is as shown in the appendix. Figure 2 as shown.

[0050] When the slag inside the dry slag discharger passes through the sieve plate 101b, the finer slag will pass through the sieve plate 101b and enter the funnel 102b, and then be guided by the funnel 102b into the collection cylinder 103b. A base needs to be adapted at the bottom end of the collection cylinder 103b to prevent the fine slag from leaking out of the collection cylinder 103b.

[0051] The dust baffle 103a is fixedly connected to the top of the collection cylinder 103b and connected to the bottom end of the funnel 102b, so as to fix the collection cylinder 103b. In addition, when the fine slag enters the inside of the collection cylinder 103b, under the shielding of the dust baffle 103a, it can also prevent the floating dust from floating out, thus protecting the working environment of the workers.

[0052] Embodiment 2

[0053] Referring to Figure 3 and Figure 4 , this is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides that the slag discharging component 200 includes a driving component 201 and an auxiliary component 202 adaptively installed outside the collection cylinder 103b;

[0054] Among them, the driving component 201 is used to realize slag discharging, and the auxiliary component 202 is used to improve the stability of the driving component 201.

[0055] Specifically, the driving component 201 includes a main connecting rod 201a hinged outside the collection cylinder 103b, a support plate 201b hinged outside the main connecting rod 201a, and a hydraulic push rod 201c hinged outside the collection cylinder 103b;

[0056] Among them, the hydraulic push rod 201c is hinged outside the main connecting rod 201a, and the support plate 201b is arranged at the bottom end of the collection cylinder 103b.

[0057] Furthermore, the auxiliary component 202 includes a first auxiliary rod 202a and a second auxiliary rod 202b hinged outside the collection cylinder 103b, and a third auxiliary rod 202c hinged outside the second auxiliary rod 202b;

[0058] Among them, the third auxiliary rod 202c is hinged outside the support plate 201b, and the third auxiliary rod 202c is coaxially hinged with the main connecting rod 201a.

[0059] During use, when the hydraulic push rod 201c contracts, the support plate 201b will closely adhere to the bottom end of the collection cylinder 103b under the combined action of the hydraulic push rod 201c and the main connecting rod 201a.

[0060] When the fine slag falls into the inside of the collection cylinder 103b, it will be supported by the support plate 201b, so as to collect the fine slag inside the collection cylinder 103b.

[0061] When the fine slag inside the collection cylinder 103b accumulates too much, the staff activates the hydraulic push rod 201c to make the hydraulic push rod 201c expand, thereby pushing the main connecting rod 201a to drive the support plate 201b to move obliquely downward, and with the cooperation of the first auxiliary rod 202a, the second auxiliary rod 202b and the third auxiliary rod 202c, ensure the stable movement of the support plate 201b.

[0062] After the support plate 201b moves downward, the fine slag will flow out from the gap between the support plate 201b and the collection cylinder 103b. After the fine slag flows out, the staff drives the hydraulic push rod 201c to contract, so that the support plate 201b is in close contact with the collection cylinder 103b again.

[0063] Finally, the staff transports the discharged fine slag to the slag storage bin to complete the whole process.

[0064] Embodiment 3

[0065] Referring to Figure 3 、 Figure 5 and Figure 6 This is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides that the slag cleaning component 300 includes an inclined baffle 301 fixedly connected inside the collection cylinder 103b, and a blocking component 302 adaptively installed outside the collection cylinder 103b;

[0066] Among them, the blocking component 302 is used to realize automatic slag discharge and automatic reset.

[0067] Specifically, the blocking component 302 includes a hinge seat 302a fixedly connected to the outside of the collection cylinder 103b, a bottom plate 302b rotatably connected to the outside of the hinge seat 302a, a counterweight bolt 302c threadedly connected to the outside of the bottom plate 302b, and a magnet 302d clamped inside the bottom plate 302b;

[0068] Among them, the collection cylinder 103b is made of iron material.

[0069] When in use, since the collection cylinder 103b is made of iron material and the magnet 302d is clamped inside the bottom plate 302b, the bottom plate 302b will be closely attached to the bottom end of the collection cylinder 103b.

[0070] When the fine slag falls into the inside of the collection cylinder 103b, under the guiding action of the inclined baffle 301, it will accumulate at the front end of the bottom plate 302b.

[0071] When the fine slag accumulates too much, under the action of the gravity of the fine slag, the magnet 302d can no longer be adsorbed at the bottom end of the collection cylinder 103b, so that the bottom plate 302b rotates under the action of the hinge seat 302a, as shown in the Figure 6 attachment. The fine slag flows out from the gap between the bottom plate 302b and the collection cylinder 103b.

[0072] Since the outer side of the bottom plate 302b is connected with a counterweight bolt 302c, when the fine slag has flowed out, under the action of the gravity of the counterweight bolt 302c, the bottom plate 302b will rotate in the reverse direction to the initial position, so that the bottom plate 302b contacts the collection cylinder 103b again. Under the action of the magnet 302d, the bottom plate 302b and the bottom end of the collection cylinder 103b are tightly attached again.

[0073] In summary, through the mutual cooperation of the inclined baffle 301 and the blocking component 302, when the fine slag accumulates too much, the bottom plate 302b can automatically rotate to discharge the fine slag. When the fine slag has been discharged, the bottom plate 302b will automatically reset, thus completing the fully automatic discharging and resetting of the whole process without manual intervention. Since the human eye cannot observe the accumulation of fine slag inside the fine slag discharging mechanism, it is difficult to grasp the slag discharging timing. However, with this device, the fine slag can be automatically discharged when it accumulates too much without manual observation, thus reducing the burden on the staff.

[0074] Embodiment 4

[0075] Referring to Figures 1 to 6 , this is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a dry slag discharger, including a fine slag discharging mechanism, and

[0076] a main body mechanism 400, which includes a frame 401 arranged outside the installation component 100, a conveyor belt 402 adaptively installed outside the frame 401, a slag discharge port 403 opened inside the frame 401, and a slag pushing component 404 adaptively installed inside the frame 401;

[0077] Among them, the sieve plate 101b is arranged inside the slag discharge port 403, and the mounting plate 101a is bolted to the outside of the frame 401.

[0078] Specifically, the slag pushing component 404 includes a chain 404a adaptively installed inside the frame 401, and a push plate 404b fixedly connected to the outside of the chain 404a. A guide rail is arranged inside the frame 401, and the chain 404a moves along the guide rail.

[0079] In use, the slag after boiler combustion will fall onto the top of the conveyor belt 402, and there is a gap between the conveyor belt 402 and the frame 401. The finer slag will fall to the bottom of the frame 401. Therefore, it is necessary to drive the push plate 404b with the movable chain 404a to scrape the fine slag at the bottom into the slag bin. During this process, when the fine slag is scraped to the slope of the frame 401, it is difficult for the fine slag to be completely pushed up by the push plate 404b, so there will be more fine slag accumulating at the slope.

[0080] Now, the accident slag discharge door at the slope is enlarged to a slag discharge port 403, and the sieve plate 101b is clamped into the inside of the slag discharge port 403, so as to cooperate with the fine slag discharge mechanism to discharge the accumulated fine slag.
