Abstract
Description
Technical Field
[0001] The utility model belongs to the field of crushing equipment, and particularly relates to an anti-caking mechanism for the slag discharge port of a slag scraper in a waste incineration power plant. Background Technique
[0002] Waste power generation refers to a form of power generation in which municipal solid waste is burned in a special incineration boiler and then electricity is generated through a steam turbine generator set. Waste power generation is divided into two categories: waste incineration power generation and landfill gas power generation. By generating electricity from waste, the power plant can not only alleviate the problem of waste pollution, but also produce energy, turning waste into treasure. The waste residue generated by waste incineration power generation is conveyed out from the bottom of the boiler by a slag scraper, and then collected and transported by a truck. The residue generated after waste incineration is easy to agglomerate together. After the agglomerated waste residue is conveyed into the interior of the transportation tool, it occupies a large space, and the gap between adjacent waste residues is large, which will reduce the load capacity of the truck.
[0003] After the residue generated by waste incineration is conveyed out by the slag scraper, the current existing technology uses an anti-caking mechanism to prevent the waste from agglomerating into blocks. The anti-caking mechanism is generally a crushing roller. The waste residue generated by incineration falls on the crushing roller, and the crushing roller crushes the residue. Some larger waste residues need a certain amount of time to pass through the crushing roller when being crushed, resulting in the larger waste residues staying between the crushing rollers, affecting the passage of small waste residues, and further affecting the crushing efficiency, causing the waste residue to accumulate on the crushing roller. Content of the Utility Model
[0004] The utility model provides an anti-caking mechanism for the slag discharge port of a slag scraper in a waste incineration power plant to solve the technical problems mentioned in the background technique.
[0005] To achieve the above object, the utility model adopts the following technical scheme: an anti-caking mechanism for the slag discharge port of a slag scraper in a waste incineration power plant, including a material distribution box and a material distribution plate. The material distribution box includes a box body, the box body is a shell structure that is vertically through, the bottom end of the box body is integrally connected with an aggregate hopper, the bottom end of the aggregate hopper is integrally connected with a square tube, the material distribution plate is fixed in the middle of the box body in the height direction and separates the box body horizontally, a material dropping hole is opened on the material distribution plate, discharge holes are symmetrically opened on both sides of the position above the material distribution plate on the box body, feed holes are symmetrically opened on both sides of the position below the material distribution plate on the box body, crushing components are arranged at the discharge holes and the feed holes, and a crushing mechanism is installed at the square tube.
[0006] By adopting the above technical solutions, when the mechanism processes the garbage incineration residue during use, the slag scraper conveys the garbage residue incinerated in the power plant. When the incinerated garbage residue is conveyed to the slag outlet, it falls into the interior of the box body. First, the garbage residue slides along the side wall of the material distribution plate. During the sliding process, the small residue falls downward through the material dropping holes on the surface of the material distribution plate, and the large garbage residue falls into the interior of the crushing component through the material discharging hole for crushing. There are two material distribution plates. The upper material distribution plate can separate the relatively large residue and guide it into the interior of the crushing component, and the lower material distribution plate can separate the relatively small residue and guide it into the interior of the crushing component, improving the screening efficiency.
[0007] Preferably, the crushing component includes a housing fixedly connected to the outer wall of the box body. The housing is a shell structure facing the opening of the box body and covers the material discharging hole and the feeding hole. A partition plate is fixed inside the housing at the top of the feeding hole. A number of material dropping holes are evenly formed on the surface of the partition plate. An L-shaped support plate is fixedly installed on the outer side of the housing away from the box body. An electric push rod is fixedly installed on the L-shaped support plate along the horizontal direction. An opening is formed on the housing, and the end of the electric push rod is fixedly connected to a squeezing plate that can penetrate in and out of the housing.
[0008] By adopting the above technical solutions, the garbage residue that falls into the interior of the crushing component lands on the partition plate, and the electric push rod is extended to drive the squeezing plate to advance to squeeze and crush the garbage residue. Then the electric push rod is retracted, and the crushed garbage residue falls through the material dropping holes to the bottom end of the housing and slides along the bottom end of the housing and finally returns to the interior of the box body through the feeding hole again.
[0009] Preferably, the squeezing plate includes a vertical plate and a horizontal plate fixed to the top end of the vertical plate. The horizontal plate matches the opening of the housing.
[0010] By adopting the above technical solutions, during the retraction process of the squeezing plate, the garbage residue that falls on the top end of the squeezing plate will be pushed down inside the housing.
[0011] Preferably, two material distribution plates are arranged side by side at intervals in the height direction. The material dropping holes of the upper material distribution plate are wider than those of the lower material distribution plate, and the width of the material dropping holes is the same as that of the lower material dropping holes.
[0012] By adopting the above technical solutions, the falling speed of the material can be buffered to avoid accumulation.
[0013] Preferably, the material distribution plate is in an inverted V-shaped structure with the middle high and both ends low.
[0014] By adopting the above technical solutions, the falling material can be made to slide, facilitating the falling.
[0015] Preferably, the crushing mechanism includes two crushing rollers rotatably connected side by side inside a square cylinder, and two motors respectively corresponding to the crushing rollers are fixedly connected to the outside of the square cylinder.
[0016] By adopting the above technical solution, the crushing work is finally completed.
[0017] The beneficial effects of the present utility model are embodied in that when the mechanism processes the refuse incineration residue during use, the slag scraper conveys the incinerated refuse residue out. When the refuse residue is conveyed to the slag outlet, it drops into the interior of the box body. First, the refuse residue will slide along the side wall of the material distribution plate. During the sliding process, the small residue will drop downward through the material dropping holes on the surface of the material distribution plate, and the large residue will fall into the interior of the crushing component through the discharge holes for crushing. There are two material distribution plates. The upper material distribution plate can separate the relatively large residue and guide it into the interior of the crushing component, and the lower material distribution plate can separate the relatively small residue and guide it into the interior of the crushing component, improving the screening efficiency. The refuse residue that drops into the interior of the crushing component falls onto the partition plate, and the electric push rod is extended to drive the extrusion plate to advance to extrude and crush the refuse residue. Then the electric push rod is retracted, and the crushed refuse residue drops through the blanking hole to the bottom end of the outer shell and slides along the bottom end of the outer shell and finally returns to the interior of the box body again through the feed hole. During the retraction process of the extrusion plate, the refuse residue that drops onto the top end of the extrusion plate will be pushed down inside the outer shell. The refuse residue sorted by the two material distribution plates and the residue crushed by the crushing component fall into the interior of the square cylinder, and the two reduction motors drive the two crushing rollers to rotate to further pulverize the refuse residue, completely avoiding the caking of the refuse residue.

Detailed Implementation Manner
[0024] The technical solutions of the present utility model will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solutions of the present utility model, rather than being construed as a limitation to the technical solutions of the present utility model.
[0025] Combined with Figures 1-4 , a slag outlet anti-caking mechanism for a slag conveyor in a waste incineration power plant, includes a material distribution box 1 and a material distribution plate 2. The material distribution box 1 includes a box body 11. The box body 11 is a shell structure that is vertically through. The bottom end of the box body 11 is integrally connected with an aggregate hopper 12. The bottom end of the aggregate hopper 12 is integrally connected with a square cylinder 13. The material distribution plate 2 is fixed in the middle of the box body 11 in the height direction and separates the box body 11 horizontally. A blanking hole 21 is opened on the material distribution plate 2. Discharge holes 3 are symmetrically opened on both sides of the box body 11 at the position above the material distribution plate 2. Feed holes 4 are symmetrically opened on both sides of the box body 11 at the position below the material distribution plate 2. Crushing components 5 are arranged at the discharge holes 3 and the feed holes 4. A crushing mechanism 6 is installed at the square cylinder 13.
[0026] When this mechanism processes the waste incineration residues during use, the slag conveyor conveys the waste residues incinerated in the power plant. When the incinerated waste residues are conveyed to the slag outlet and fall into the interior of the box body 11, first, the waste residues will slide down along the side wall of the material distribution plate 2. During the sliding process, small residues will fall downward through the blanking holes 21 on the surface of the material distribution plate 2, and large waste residues will fall into the interior of the crushing component 5 through the discharge holes 3 for crushing. There are two material distribution plates 2. The upper material distribution plate 2 can separate relatively large residues and guide them into the interior of the crushing component 5, and the lower material distribution plate 2 can separate relatively small residues and guide them into the interior of the crushing component 5, improving the screening efficiency.
[0027] The crushing component 5 includes an outer shell 51 fixedly connected to the outer wall of the box body 11. The outer shell 51 is a shell structure that opens towards the box body 11 and covers the discharge holes 3 and the feed holes 4. A partition board 52 located at the top of the feed hole 4 is fixed inside the outer shell 51. A plurality of blanking holes 53 are evenly opened on the surface of the partition board 52. An L-shaped support plate 55 is fixed on the outer side of the outer shell 51 away from the box body 11. An electric push rod 56 along the horizontal direction is fixedly installed on the L-shaped support plate 55. An opening is made on the outer shell 51, and the end of the electric push rod 56 is fixedly connected to an extrusion plate 54 that can penetrate in and out of the outer shell 51.
[0028] The garbage residue that has fallen inside the shredding component 5 lands on the partition plate 52. The electric push rod 56 is extended to drive the extrusion plate 54 to advance and extrude and crush the garbage residue. Then, the electric push rod 56 is retracted, and the crushed garbage residue falls through the material discharge hole 53 to the bottom end of the outer shell 51, and slides along the bottom end of the outer shell 51 and finally returns to the inside of the box body 11 through the feed hole 4 again.
[0029] The extrusion plate 54 includes a vertical plate and a horizontal plate fixed at the top end of the vertical plate. The horizontal plate matches the opening of the outer shell 51. During the retraction process of the extrusion plate 54, the garbage residue that has fallen on the top end of the extrusion plate 54 will be pushed down by the inside of the outer shell 51.
[0030] Two material distribution plates 2 are arranged side by side at intervals in the height direction. The material dropping hole 21 of the upper material distribution plate 2 is wider than the material dropping hole 21 of the lower material distribution plate 2. The width of the material discharge hole 53 is the same as the width of the lower material dropping hole 21, which can buffer the material dropping speed and avoid accumulation.
[0031] The material distribution plate 2 has an inverted V-shaped structure with the middle high and both ends low, which can make the falling material slide and facilitate falling.
[0032] The crushing mechanism 6 includes two crushing rollers 61 rotatably connected side by side inside the square cylinder 13. Two motors 62 corresponding to the crushing rollers 61 are fixedly connected to the outside of the square cylinder 13, and finally the crushing work is completed.
[0033] The beneficial effects of the present utility model are reflected in that when the mechanism processes the garbage incineration residue during use, the slag collector conveys the incinerated garbage residue. When the garbage residue is conveyed to the slag outlet, it falls into the inside of the box body 11. First, the garbage residue will slide along the side wall of the material distribution plate 2. During the sliding process, the small residue will fall downward through the material dropping hole 21 on the surface of the material distribution plate 2, and the large residue falls through the material discharge hole 3 into the inside of the shredding component 5 for crushing. There are two material distribution plates 2. The upper material distribution plate 2 can separate the relatively large residue and guide it into the inside of the shredding component 5, and the lower material distribution plate 2 can separate the relatively small residue and guide it into the inside of the shredding component 5, improving the screening efficiency. The garbage residue that has fallen inside the shredding component 5 lands on the partition plate 52. The electric push rod 56 is extended to drive the extrusion plate 54 to advance and extrude and crush the garbage residue. Then, the electric push rod 56 is retracted, and the crushed garbage residue falls through the material discharge hole 53 to the bottom end of the outer shell 51, and slides along the bottom end of the outer shell 51 and finally returns to the inside of the box body 11 through the feed hole 4 again. During the retraction process of the extrusion plate 54, the garbage residue that has fallen on the top end of the extrusion plate 54 will be pushed down by the inside of the outer shell 51. The garbage residue sorted by the two material distribution plates 2 and the residue crushed by the shredding component 5 fall into the inside of the square cylinder 13. The two reduction motors 62 drive the two crushing rollers 61 to rotate to further crush the garbage residue, completely avoiding the caking of the garbage residue.
[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
