[0001] The utility model relates to the technical field of slag discharge, and in particular to a chute used for a slag discharger. Background Art
[0002] The slag from the incinerator enters the slag discharger through the slag outlet. The wet slag from the slag discharger is sent into the chute by the reciprocating action of the scraper of the slag discharger, and then into the slag pit through the chute. The slag pit is generally completely isolated from the incineration workshop, and ventilation in the slag pit is achieved through the top ventilation fan.
[0003] In the related technology, the concrete walls of the chute and the slag pit cannot be effectively sealed, and the odor in the slag pit can easily leak into the incineration workshop. In addition, when the slag discharger needs to be repaired, a large amount of wet slag in the slag discharger needs to be cleaned out. Since the slag discharger and the slag pit are not in the same workshop, the cleaned wet slag cannot be transferred to the slag pit in time, and a large amount of wet slag is piled on the spot in the incineration workshop, which causes the local environment on site to deteriorate.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0027] like Figure 1-Figure 4 As shown, the chute for the slag discharger 100 according to the embodiment of the utility model includes a chute body 1 and a sealing assembly 2.
[0028] The first end of the chute body 1 is connected to the slag discharge port of the slag discharger 100, the second end of the chute body 1 passes through the wall 200 and is arranged adjacent to the slag pit 300, and the chute body 1 is tilted toward the slag discharger 100 in the direction in which the second end of the chute body 1 points to the first end of the chute body 1. The sealing assembly 2 includes an annular body 21, the inner peripheral wall of the sealing assembly 2 is connected to the outer peripheral wall of the chute body 1, the sealing assembly 2 is located on a side of the wall 200 adjacent to the slag pit 300, and the side wall of the sealing assembly 2 away from the slag pit 300 contacts the wall 200 to block the gap between the side wall of the second end of the chute body 1 and the wall 200.
[0029] Specifically, Figure 1 As shown, the right end of the chute body 1 (i.e., the first end of the chute body 1) can be detachably connected to the slag discharge port of the slag discharger 100 by bolts and other connectors, and the left end of the chute body 1 (i.e., the second end of the chute body 1) penetrates the wall 200 to facilitate the slag discharged by the slag discharger 100 to pass into the slag pit 300. The chute body 1 is generally arranged tilted toward the upper left. The annular body 21 is square ring-shaped, and the inner circumferential wall of the annular body 21 is adapted to the outer circumferential wall of the second end of the chute body 1, so that the annular body 21 can be sleeved on the outer circumferential surface of the chute body 1. The annular body 21 and the chute body 1 can be connected by welding, bonding or clamping, and the annular body 21 can also block the gap between the chute body 1 and the wall 200.
[0030] It is understandable that a through hole is provided on the wall 200, and the right end of the chute body 1 can pass through the through hole. There is a gap between the peripheral side wall of the chute body 1 and the hole wall of the through hole, which easily causes the odor of the slag pit 300 to flow to the incineration workshop through the gap, causing pollution to the production environment. Therefore, the annular body 21 is installed at the second end of the chute body 1 to block the gap between the peripheral side wall of the chute body 1 and the hole wall of the through hole, which can prevent the odor of the slag pit 300 from flowing to the incineration workshop through the gap.
[0031] Preferably, the annular body 21 is made of steel material, and the annular body 21 is connected to the chute body 1 by welding to improve the sealing effect between the annular body 21 and the chute body 1 .
[0032] That is to say, the chute for the slag discharger 100 of the embodiment of the utility model is equipped with an annular body 21 at the second end of the chute body 1, so that the annular body 21 can block the gap between the second end of the chute body 1 and the wall 200, thereby preventing the odor in the slag pit 300 from flowing from the gap between the second end of the chute body 1 and the wall 200 to the incineration workshop (i.e., the workshop where the slag discharger 100 is located).
[0033] In some embodiments, the sealing assembly 2 further includes a mounting member 22, the annular body 21 has a mounting hole 23, and the mounting hole 23 is formed along the thickness direction of the annular body 21 (eg Figure 1 The mounting member 22 passes through the mounting hole 23 and is connected to the wall 200.
[0034] It is understandable that if Figure 1-Figure 4 As shown, during installation, according to the matching relationship between the annular body 21 and the chute body 1, a hole is drilled on the wall at an appropriate height, and after the mounting hole 23 of the annular body 21 is aligned with the drilled hole, one end of the mounting member 22 is passed through the mounting hole 23 and placed in the drilled hole. At this time, due to the matching of the mounting hole 23 and the mounting member 22, the mounting member 22 can serve as a support for the annular body 21, which facilitates the subsequent welding process.
[0035] Optionally, the mounting hole 23 may be a threaded hole, and the mounting member 22 may be a bolt matching the threaded hole.
[0036] Preferably, the mounting hole 23 is located above the second end of the chute body 1, the mounting hole 23 is a strip-shaped hole, and the length direction of the mounting hole 23 is consistent with the horizontal direction.
[0037] It is understandable that if Figure 2As shown, the mounting hole 23 is a strip-shaped hole, which facilitates the installation of the annular body 21 and the drilled hole on the wall 200, and avoids a certain position compensation between the drilled hole and the mounting hole 23. In addition, after the mounting member 22 is inserted into the drilled hole through the mounting hole 23, since the mounting hole 23 is a strip-shaped hole and extends in the horizontal direction, the annular body 21 can also be moved in the horizontal direction relative to the chute body 1, so that the relative position of the annular body 21 relative to the chute body 1 can be adjusted, which can ensure the welding position of the annular body 21 and the chute body 1, and avoid the existence of a gap between the annular body 21 and the wall 200.
[0038] In other embodiments, there are multiple mounting holes 23, and the multiple mounting holes 23 are arranged at intervals along the circumferential direction of the center line of the annular body 21. There are multiple mounting members 22, and the multiple mounting members 22 correspond to the multiple mounting holes 23. It is understandable that before welding the annular body 21 and the chute body 1, it is necessary to use a lifting device to transport the annular body 21 to the vicinity of the chute body 1, which is cumbersome and takes a long time. Therefore, the cooperation of multiple mounting holes 23 and mounting members 22 is used to pre-install the annular body 21 on the wall 200, which avoids the long-term use of lifting equipment and improves installation efficiency.
[0039] In some embodiments, the annular body 21 further includes an annular protrusion 24 . In a plane orthogonal to the center line of the annular body 21 , the projection profile of the annular protrusion 24 is similar to the projection profile of the annular body 21 . The annular protrusion 24 is located on the side of the annular body 21 adjacent to the wall 200 .
[0040] Specifically, Figure 3 As shown, the projection profile of the annular protrusion 24 is a square ring, the annular body 21 is connected to the chute body 1, and the annular protrusion 24 can be in sealing contact with the surface of the wall 200 to prevent the odor of the slag pit 300 from flowing into the incineration workshop.
[0041] It can be understood that the annular protrusion 24 is located on the side of the annular body 21 adjacent to the wall 200. When the annular body 21 is connected to the chute body 1, the annular protrusion 24 contacts the side wall surface of the wall 200, thereby avoiding a small gap between the annular body 21 and the wall 200 due to welding, and further ensuring the sealing function of the annular body 21.
[0042] Optionally, there are multiple annular protrusions 24, and the multiple annular protrusions 24 are arranged around the center line of the annular body 21, and there is a gap between two adjacent annular protrusions 24. It can be understood that Figure 3 As shown, a plurality of annular protrusions 24 are arranged in a concentric square ring structure in sequence to increase the contact area between the annular body 21 and the wall 200. In addition, the flow path between the surface of the wall 200 and the annular body 21 is increased. Figure 4 As shown, the presence of the plurality of annular protrusions 24 makes the flow path between the surface of the wall 200 and the annular body 21 S-shaped.
[0043] Preferably, the annular protrusion 24 is made of a soft material. It is understandable that the annular protrusion 24 can be made of a soft rubber material, or a sponge material with low air permeability, or of course other soft materials.
[0044] In some embodiments, the chute for the slag discharger 100 of the embodiment of the utility model further includes an inspection door 11, and the chute body 1 also has an inspection port, and the inspection door 11 is installed in the inspection port to seal the inspection port.
[0045] Specifically, Figure 1 As shown, the inspection port is opened at the front side of the chute body 1, and the inspection door 11 can be installed in the inspection port by hinges.
[0046] It is understandable that in actual production, the inspection door 11 is in a normally closed state to ensure that the slag passes into the slag pit 300 through the chute body 1. When the residue inside the chute body 1 needs to be cleaned or the slag discharger 100 needs to be repaired, the inspection door 11 can be opened to facilitate the operator to directly clean out the inspection door 11 or clean out a large amount of wet slag discharged from the slag discharger 100, avoiding the operator from transporting the slag multiple times between the two workshops, greatly improving the slag cleaning efficiency.
[0047] Preferably, the ratio of the distance between the inspection port and the wall 200 to the distance between the first end of the chute body 1 and the wall 200 is greater than or equal to 0.2 and less than or equal to 0.6. Figure 1 As shown, the distance between the inspection port and the wall 200 is a, and the distance between the first end of the chute body 1 and the wall 200 is b, then 0.2≤a / b≤0.6. In other words, the smaller the distance between the inspection port and the wall 200, the more inconvenient it is for the operator to perform the inspection; the larger the distance between the inspection port and the wall 200, the higher the height of the inspection port, which may cause certain safety hazards to the operator due to the oblique upward arrangement of the chute body 1.
[0048] Therefore, preferably, the ratio of the distance between the inspection port and the ground 400 to the distance between the first end of the chute body 1 and the ground 400 is less than or equal to 0.6. Figure 1 As shown, the distance between the inspection port and the ground 400 is c, and the distance between the first end of the chute body 1 and the ground 400 is d, then c / d≤0.6, so as to avoid safety hazards to operators due to the excessive height of the inspection port and improve the safety of production conditions.
