[0001] The present invention relates to the technical field of solid waste storage and transportation, and in particular to a solid waste storage and transportation system for coordinating the treatment of multiple solid wastes with a coal-fired boiler. Background Art

[0002] In the prior art, coal-fired boilers generate a large amount of solid waste after use. The solid waste mainly includes various types, including cyanamide filter residue, coal slime and sludge, which are transported to the solid waste storage bin in the power plant by dump trucks. The solid waste storage bin is a temporary storage space for materials, which can be temporarily stored. When it needs to be processed, it is transported to the processing station for processing by a transport device. Based on this, the present application proposes a solid waste storage and transportation system for the coordinated treatment of multiple solid wastes by coal-fired boilers;

[0003] After searching, the Chinese patent application number 202320301900.4 discloses a solid waste recycling, screening and storage device, comprising: a device shell; a guide plate arranged inside the device shell; a magnetic attraction mechanism mounted under the guide plate; a screening mechanism arranged under the magnetic attraction mechanism; a storage mechanism located under the screening mechanism; a transmission mechanism arranged on the device shell for driving the screening mechanism to move; and a dust handling mechanism arranged on the device shell; wherein the screening mechanism comprises: a first screening plate and a second screening plate, a screen is arranged inside the first screening plate, and a transition arc edge is arranged at one end of the first screening plate.

[0004] A solid waste recovery, screening and storage device in the above patent has the following shortcomings: when using the first screening plate for screening, the solid waste intercepted by the first screening plate cannot be discharged in time, and if the solid waste contains moisture, it will adhere to the first screening plate, thereby affecting the screening efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a solid waste storage and transportation system for the coordinated treatment of multiple solid wastes by coal-fired boilers.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The cam is connected to the upper and lower ends of the cam, and the cam is connected to the upper and lower ends of the cam by a screw bolt, and the cam is connected to the upper and lower ends of the cam by a screw bolt.

[0008] Preferably, a hopper is welded at the bottom of the storage box, and a screw conveyor is fixed at the bottom of the hopper.

[0009] Preferably, the conveying part comprises a conveyor 1 and a weighing assembly, and the conveyor 1 is in a "Z" shape.

[0010] Preferably, the weighing assembly comprises a weighing device and a fixed plate, the fixed plate is fixed to a top of the conveyor, and the weighing device is fixed to an outer wall of the top of the fixed plate.

[0011] Preferably: the material distribution part comprises conveyor 2, conveyor 3 and a support platform, and conveyor 3 and conveyor 2 are both placed on the top of the support platform.

[0012] Preferably: a material distribution conveyor for feeding materials to the second conveyor and the third conveyor is also placed on the top of the support platform.

[0013] Preferably: a slide, a driving rod and a retaining plate are fixed to the top outer wall of the conveyor, the slide is fixed to the top of the conveyor, the retaining plate is movably connected to the inner wall of the slide, and the driving rod is movably connected between the inner walls on both sides of the retaining plate.

[0014] On the basis of the above scheme: a vertical plate is fixed on the top outer wall of the conveyor, and a rotating rod is movably connected between the two vertical plates, a toggle rod is welded on the outer wall of the rotating rod, and a waist-shaped hole matching the outer diameter of the driving rod is opened on the surface of the toggle rod.

[0015] Based on the above solution, preferably: a driving motor is fixed to the outer wall of one side of the vertical plate, and the output end of the driving motor is connected to one end of the rotating rod through a coupling.

[0016] Based on the above solution, it is further preferred that: a shifting plate is welded to the outer wall of the bottom of the lifting frame, and transverse rods are welded on both sides of the shifting plate.

[0018] 1. The hydraulic cylinder can be used to drive the hydraulic cylinder to open or close, so that when solid waste needs to be stored, the cover can be opened to ensure that the solid waste can be introduced into the storage box through the gap between the cover and the storage box.

[0019] 2. The slide groove and the slide seat are used to drive the scraper frame to move up and down along the inner wall of the storage box during the opening and closing process. The scraper frame scrapes off the solid waste attached to the inner wall of the storage box during the up and down movement.

[0020] 3. The downward movement of the lifting frame allows the two groups of cross plates to move relative to each other, thereby driving the two groups of push plates to move relative to each other to push the solid waste on the cross plates. The inclined plates can be used to guide the solid waste attached to the cross plates out of the openings on the side walls of the storage box.

[0021] 4. By providing a moving plate and a transverse rod, the solid waste can be moved in the process of moving up and down, so as to avoid the accumulation of solid waste in the hopper.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Embodiment 1:

[0037] A solid waste storage and transportation system for the coordinated treatment of multiple solid wastes by coal-fired boilers, such as Figures 1 to 10As shown, it includes a storage part, a conveying part and a material distribution part. The storage part includes a storage box 1, a sealing plate 19 and a cover plate 20. A heating plate 35 is fixed to the outer wall of one side of the storage box 1 by bolts. The sealing plate 19 is fixed to the outer wall of the top of the storage box 1 by bolts, and the cover plate 20 is connected to one end of the sealing plate 19 by a hinge. A hydraulic cylinder 2 is rotatably connected between the sealing plate 19 and the cover plate 20, and a slide groove 26 is provided at the bottom of the cover plate 20. A scraper frame 21 is slidably connected to the inner wall of the storage box 1, and a lifting frame 31 is welded to the bottom of the scraper frame 21. A vertical rod 28 is welded on the top of the scraper frame 21, and one end of the vertical rod 28 is rotatably connected to a slide seat 27, and the slide seat 27 and the slide slot 26 are slidably connected. A cross plate 29 is slidably connected to the top of the lifting frame 31, and a push plate 30 is welded on one end of the cross plate 29, and the two cross plates 29 are cross-arranged, and an adjustment seat 2 34 is welded on the inner wall of one side of the storage box 1, and an adjustment seat 1 32 is welded on the bottom of the cross plate 29, and a connecting rod 33 is rotatably connected between the adjusting seat 1 32 and the adjusting seat 2 34, and an inclined plate 22 is welded on the outer wall of one side of the connecting rod 33;

[0038] When solid waste needs to be stored, the hydraulic cylinder 2 is first used to drive the output end thereof to move so that the cover plate 20 is unfolded along the sealing plate 19, and the solid waste is loaded by using the gap between the cover plate 20 and the storage box 1. The cover plate 20 drives the slide seat 27 to move by using the slide groove 26 during the opening process, and the slide seat 27 drives the vertical rod 28 and the scraper frame 21 to move up in the vertical direction during the movement process, and the scraper frame 21 drives the lifting frame 31 to move synchronously during the upward movement process. When the two cross plates 29 block the top of the lifting frame 31, the cross plates 29 can be used to buffer larger solid waste attached to the cross plates 29. When the solid waste storage is completed and the solid waste attached to the cross plates 29 needs to be cleaned, the hydraulic cylinder 2 is used to drive the cover plate 20 to gradually move from the open state to the closed state. During the resetting process of the cover plate 20, the slide seat 27 is driven to slide along its inner wall by using the slide groove 26. The vertical rod 28 drives the scraper frame 21 to move downward along the top of the storage box 1. The scraper frame 21 scrapes the solid waste attached to the inner wall of the storage box 1 during the movement. The scraper frame 21 drives the lifting frame 31 to move downward during the downward movement. The connecting rod 33 is used to convert the vertical movement of the lifting frame 31 into the lateral movement of the cross plate 29 along the lifting frame 31. The movement directions of the two cross plates 29 are opposite. During the relative movement of the two cover plates 20, the push plate 30 pushes the solid waste attached to the cross plate 29. The pushed solid waste attached to the cross plate 29 slides along the inclined plate 22 and is finally discharged through the opening of the side wall of the storage box 1. The cover plate 20 can clean the solid waste attached to the cross plate 29 while covering it. The heating plate 35 can be provided to heat the solid waste when the temperature is low to avoid freezing of the solid waste due to the influence of temperature and causing blockage.

[0039] Six temperature points are designed around the storage box 1 to monitor the temperature of the solid waste storage bin, and a material level alarm is designed on the top of the storage box 1 to monitor the material level in the solid waste storage bin.

[0040] Furthermore, a hopper 23 is welded to the bottom of the storage box 1, and a screw conveyor 7 is fixed to the bottom of the hopper 23 by bolts;

[0041] The solid waste is collected by providing a hopper 23 , and when the solid waste needs to be transported, the screw conveyor 7 is used to transport the solid waste horizontally to the transporting part for transportation.

[0042] Further, the conveying part includes a conveyor 3 and a weighing assembly, the conveyor 3 is in a "Z" shape, and the weighing assembly includes a weighing device 11 and a fixing plate 12, the fixing plate 12 is fixed to the top of the conveyor 3 by bolts, and the weighing device 11 is fixed to the outer wall of the top of the fixing plate 12;

[0043] By setting the conveyor 3 into a "Z" shape, the solid waste can be transported to a certain height. In this embodiment, the inclined section angle of the "Z"-shaped belt conveyor is preferably 38°.

[0044] When the solid waste is transported to the top of the conveyor 3, the solid waste can be weighed using the weighing device 11, so that the solid waste can be unloaded after being weighed to a certain weight.

[0045] Furthermore, the material distribution part includes a conveyor 2 4, a conveyor 3 5 and a support platform 6, the conveyor 3 5 and the conveyor 2 4 are both placed on the top of the support platform 6, and a material distribution conveyor 8 for feeding the conveyor 2 4 and the conveyor 3 5 is also placed on the top of the support platform 6;

[0046] The distribution conveyor 8 is provided to receive the solid waste outputted by the conveyor 1 3 . The conveyor belt of the distribution conveyor 8 can be reversed to make the solid waste fall onto the conveyor 2 4 or the conveyor 3 5 . The solid waste can be transported to different locations by means of the conveyor 2 4 and the conveyor 3 5 .

[0047] Furthermore, a moving plate 24 is welded to the outer wall of the bottom of the lifting frame 31, and transverse rods 25 are welded to both sides of the moving plate 24;

[0048] The provision of the moving plate 24 and the transverse rod 25 allows the solid waste to move in the process of moving up and down, thereby preventing the solid waste from accumulating and clogging in the hopper 23 .

[0049] When this embodiment is in use, the hydraulic cylinder 2 is first used to drive the cover plate 20 to open, and then the solid waste to be stored is introduced into the storage box 1. The cross plate 29 can be used to buffer stones and metals to reduce their impact on the hopper 23 and the screw conveyor 7. The solid waste is transported horizontally by the screw conveyor 7 and then moved to the conveyor 3. The conveyor 3 is used to lift the solid waste. When the solid waste is moved to the distribution conveyor 8, the forward and reverse rotation of the belt of the distribution conveyor 8 is controlled so that the solid waste is transported to the conveyor 2 4 or the conveyor 3 5 for feeding according to the set needs.

[0050] Embodiment 2:

[0051] A solid waste storage and transportation system for the coordinated treatment of multiple solid wastes by coal-fired boilers, such as Figures 1 to 10 As shown, in order to ensure the accuracy of solid waste weighing; this embodiment makes the following supplements on the basis of embodiment 1: the outer wall of the top of the conveyor 3 is fixed with a slide 9, a driving rod 13 and a retention plate 14 by bolts, the slide 9 is fixed to the top of the conveyor 3 by bolts, and the retention plate 14 is slidably connected to the inner wall of the slide 9, and the driving rod 13 is rotatably connected between the inner walls on both sides of the retention plate 14, the outer wall of the top of the conveyor 3 is fixed with a vertical plate 15 by bolts, and a rotating rod 18 is rotatably connected between the two vertical plates 15, the outer wall of the rotating rod 18 is welded with a toggle rod 10, and the surface of the toggle rod 10 is provided with a waist-shaped hole 17 adapted to the outer diameter of the driving rod 13, the outer wall of one side of the vertical plate 15 is fixed with a driving motor 16 by bolts, and the output end of the driving motor 16 is connected to one end of the rotating rod 18 through a coupling;

[0052] When it is necessary to weigh the solid waste, the driving motor 16 is first used to drive the rotating rod 18 and the toggle rod 10 to tilt toward the direction close to the end of the conveyor 3, and the waist-shaped hole 17 is used to convert the circular motion of the toggle rod 10 into the vertical motion of the interception plate 14 along the slide 9. The interception plate 14 temporarily intercepts the solid waste during the downward movement. At this time, the other interception plate 14 is driven by the toggle rod 10 to move up along its corresponding slide 9, so that the conveyor 3 can continue to transport the solid waste to the weighing At the top of the device 11, the solid waste is weighed by the weighing device 11. When the solid waste reaches the set weight, the driving motor 16 is used to drive the toggle rod 10 to rotate in the opposite direction, so that the two intercepting plates 14 switch positions with each other. The intercepting plates 14 that originally intercepted the solid waste move up, and the other set of intercepting plates 14 move down to intercept the solid waste transported by the conveyor 3, so that the solid waste that reaches the weighing weight on the weighing device 11 is transported by the conveyor 3 to the material distribution conveyor 8, thereby ensuring the accuracy of the solid waste weighing.
