[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-3 As shown, a dust collection device for the feed inlet of a slanted zipper in one embodiment of the present invention includes a slanted zipper body 1 and a dust collection device body 2.

[0030] like Figures 1-3 As shown, the inclined zipper body 1 includes a feed inlet 11 and a hopper 12. The feed inlet 11 is located directly above the hopper 12. The molten material cooled in the grate cooler is fed into the feed inlet 11 and then into the hopper 12 for conveying by the inclined zipper machine. A base 16 is fixedly connected to the bottom of the hopper 12, which ensures the stability of the inclined zipper installation.

[0031] like Figures 1-3 As shown, the feed inlet 11 consists of an upper tapered tube and a lower round tube. The upper tapered tube of the feed inlet 11 is designed with a large opening at the top and a small opening at the bottom, which makes it convenient for the feed inlet 11 to transport the clinker.

[0032] like Figures 1-3 and Figure 2 As shown, multiple wear-resistant barbs 13 are fixedly connected to the inner wall of the tapered tube at the upper end of the feed inlet 11. The multiple wear-resistant barbs 13 are arranged in an interlaced manner so that the clinker in the feed inlet 11 will be guided and limited by the wear-resistant barbs 13 during conveying.

[0033] like Figure 3 As shown, a guide pipe 14 is fixedly connected inside the circular tube at the lower end of the feed inlet 11, through which the clinker is guided. A wear-resistant layer 15 is provided on the inner side wall of the guide pipe 14. The wear-resistant layer 15 is provided on the guide pipe 14 to prevent the clinker from wearing down the guide pipe 14.

[0034] like Figures 2-4As shown, the draft tube 14 is set as a tapered pipe with a large upper end and a small lower end. The diameter of the upper end opening of the draft tube 14 matches the inner diameter of the lower end circular tube of the feed port 11, so that the clinker in the feed port 11 is gathered to the center when flowing out of the lower end of the feed port 11 after being guided by the draft tube 14, thereby reducing the amount of leaked clinker between the feed port 11 and the hopper 12 when the clinker enters the hopper 12 from the feed port 11.

[0035] As shown, Figures 2-4 The dust collection device body 2 includes a material blocking plate 21 for blocking the leaked clinker when the clinker enters the hopper 12 from the feed port 11. The material blocking plate 21 is provided with a plurality of material blocking plates 21 which are respectively press-bonding on the outer side walls of the hopper 12 in a movable manner, so that the material blocking plate 21 can block all the side walls of the hopper 12 and block the leaked clinker in all directions. At the same time, the material blocking plate 21 is installed in a movable manner, so that the tightness between the material blocking plate 21 and the hopper 12 can be adjusted. The side of the material blocking plate 21 away from the side wall of the hopper 12 is provided with a fixed plate 22, which assists in adjusting the tightness between the material blocking plate 21 and the hopper 12. The material blocking plate 21 is fixedly connected with a plurality of first threaded rods 23 away from the side wall of the hopper 12, and the ends of the first threaded rods 23 away from the material blocking plate 21 are movably penetrated through the fixed plate 22 and placed outside the fixed plate 22, so that the first threaded rods 23 can move on the fixed plate 22, thereby adjusting the distance between the material blocking plate 21 and the fixed plate 22. The first threaded rod 23 is sleeved with a compression spring 24, which is arranged between the material blocking plate 21 and the fixed plate 22. Adjusting the distance between the material blocking plate 21 and the fixed plate 22 can change the elastic force of the compression spring 24 on the material blocking plate 21 and the fixed plate 22, thereby adjusting the tightness between the material blocking plate 21 and the hopper 12.

[0036] Preferably, the connection between the material blocking plate 21 and the hopper 12 adopts the press-bonding manner, so that the tightness between the material blocking plate 21 and the hopper 12 can be adjusted, and at the same time, when the amount of leaked clinker is large, the impact force of the leaked clinker on the side wall of the material blocking plate 21 can be effectively buffered by the compression spring 24, so that the material blocking plate 21 has good flexibility in blocking the leaked clinker, thereby increasing the practicability of the device.

[0037] As shown, Figures 1-3 and Figure 3As shown, the side wall of the fixed plate 22 is provided with a through hole, and the first threaded rod 23 is movably penetrated through the fixed plate 22 through the through hole at the end away from the material blocking plate 21, so that the material blocking plate 21 can drive the fixed plate 22 to move on the first threaded rod 23, thereby adjusting the distance between the material blocking plate 21 and the fixed plate 22. The end of the first threaded rod 23 outside the fixed plate 22 is threadedly connected with a pair of limiting nuts 25, and the end of the first threaded rod 23 outside the fixed plate 22 is threadedly connected with a pair of limiting nuts 25. The distance between the material blocking plate 21 and the fixed plate 22 is limited by the limiting nuts 25; at the same time, the limiting nuts 25 are provided with a pair, so that the limiting nuts 25 stably clamp the material blocking plate 21 and the fixed plate 22, avoiding loosening of the limiting nuts 25 due to vibration during use, resulting in change of the distance between the material blocking plate 21 and the fixed plate 22.

[0038] As shown in Figure 5 , the upper end of the material blocking plate 21 is provided with a filter cloth 26, and the end of the filter cloth 26 away from the material blocking plate 21 is installed on the outer side wall of the feed inlet 11. Through the material blocking plate 21 and the filter cloth 26, the gap between the feed inlet 11 and the hopper 12 can be blocked, so that the clinker leaked between the feed inlet 11 and the hopper 12 is blocked and cannot leak out, and the clinker blocked by the filter cloth 26 flows into the hopper 12 under the action of gravity. The filter cloth 26 not only intercepts the clinker but also intercepts the dust generated by the clinker, avoiding dust leakage to affect the environment. At the same time, the filter cloth 26 is made of flexible material, so that it has a certain deformation space during use, ensuring that there is no leakage at the joint during use. The filter cloth 26 is made of high-temperature resistant material, and since the temperature of the clinker is high, the filter cloth 26 can withstand the high temperature of the clinker.

[0039] As shown in Figures 1-3 and Figure 3 , the side wall of the material blocking plate 21 close to the hopper 12 is provided with an elastic pad 27. In order to make the material blocking plate 21 be tightly sealed by pressing on the side wall of the hopper 12, the elastic pad 27 is arranged between the material blocking plate 21 and the hopper 12, so as to avoid leakage of the clinker. The elastic pad 27 is made of high-temperature resistant material, and since the temperature of the clinker is high, the elastic pad 27 can withstand the high temperature of the clinker.

[0040] As shown in Figure 5 , Figure 2 and Figure 3As shown, the second threaded rod 29 is slidably connected to the fixed plate 22 in a penetrating manner, one end of the second threaded rod 29 is fixedly connected to the limiting block 211 on the inner side of the fixed plate 22, and the other end of the second threaded rod 29 is threadedly connected to the adjusting nut 210 on the outer side of the fixed plate 22. By rotating the adjusting nut 210, the fixed plate 22 can be pushed to slide on the second threaded rod 29, thereby adjusting the distance between the blocking plate 21 and the fixed plate 22. The smaller the distance between the blocking plate 21 and the fixed plate 22, the greater the pushing force of the compression spring 24 on the blocking plate 21, so that the tightness of the pressing between the blocking plate 21 and the hopper 12 can be adjusted by adjusting the distance between the blocking plate 21 and the fixed plate 22 through the movement of the fixed plate 22 on the second threaded rod 29. At the same time, under the action of the plurality of first threaded rods 23, the movement of the fixed plate 22 is stable when adjusting the distance between the blocking plate 21 and the fixed plate 22.

[0041] As shown in the drawings, Figure 5 Figures 1-3 As shown, the second threaded rod 29 is slidably connected to the fixed plate 22 in a penetrating manner, one end of the second threaded rod 29 is fixedly connected to the limiting block 211 on the inner side of the fixed plate 22, and the other end of the second threaded rod 29 is threadedly connected to the adjusting nut 210 on the outer side of the fixed plate 22. By rotating the adjusting nut 210, the fixed plate 22 can be pushed to slide on the second threaded rod 29, thereby adjusting the distance between the blocking plate 21 and the fixed plate 22. The smaller the distance between the blocking plate 21 and the fixed plate 22, the greater the pushing force of the compression spring 24 on the blocking plate 21, so that the tightness of the pressing between the blocking plate 21 and the hopper 12 can be adjusted by adjusting the distance between the blocking plate 21 and the fixed plate 22 through the movement of the fixed plate 22 on the second threaded rod 29. At the same time, under the action of the plurality of first threaded rods 23, the movement of the fixed plate 22 is stable when adjusting the distance between the blocking plate 21 and the fixed plate 22.

[0042] In use, when the grate cooler delivers the cooled clinker into the feeding port 11, the clinker will flow in the feeding port 11, and then enter the flow guide pipe 14 after being guided and limited by the wear-resistant barbs 13, and then flow out of the feeding port 11 in a central gathering manner after being guided by the flow guide pipe 14, and then enter the hopper 12. The clinker leaked from the feeding port 11 and the hopper 12 will be intercepted by the blocking plate 21 and the filter cloth 26, and the intercepted clinker will flow into the hopper 12 under the action of gravity. Since the blocking plate 21 and the filter cloth 26 enclose the gap between the feeding port 11 and the hopper 12, the clinker is prevented from leaking out, and the setting of the blocking plate 21 and the filter cloth 26 will not affect the normal operation of the cable-stayed chain. In order to make the blocking plate 21 press and compact on the side wall of the hopper 12, the adjusting nut 210 is rotated to push the fixed plate 22 to slide on the second threaded rod 29, and at the same time the fixed plate 22 will slide on the plurality of first threaded rods 23, so that the compression spring 24 can be compressed, the elastic force of the compression spring 24 on the blocking plate 21 is greater, and the blocking plate 21 is tightly pressed on the side wall of the hopper 12.
