The dust inside the waste residue falls into the receiving box through the vibration screen plate for storage. The receiving box is located on the top of the electronic scale, which is convenient for weighing and recording the screened dust. The blocky waste residue slides out of the discharge pipe and enters the collection box due to the inclined guide of the vibration screen plate. Several baffles installed at the lowest point of the vibration screen plate are tilted in an "eight" shape to guide the waste residue. The pipe mouth of the discharge pipe coincides with the groove formed between the several baffles to avoid the discharge port being too large, resulting in the dispersion of waste residue and affecting the unified discharge. The waste residue is automatically transported and then automatically screened, avoiding the time and manpower consumption caused by the staff carrying and screening again, and at the same time avoiding the dust generated by the waste residue from spreading in the air, which reduces the air quality of the power plant workshop.

[0017] 3. The staff controls the electric structure of the automatic conveying device through the electric control box and starts the cylinder support. The telescopic end of the cylinder support rises away from the ground, releasing the fixed connection of the base. The staff pushes the automatic conveying device, and the universal wheel drives the automatic conveying device to move away from the boiler body, making it easier for the automatic conveying device to move and facilitating the separation of the automatic conveying device from the boiler body for maintenance and inspection.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Refer to the attached Figure 1 -Attached Figure 8, an automatic conveying device for boiler slag discharge in a power plant, comprising a conveying box 1, a first lifting frame 3 and a second lifting frame 4. A boiler body 2 is provided on the top of the conveying box 1. The bottom end of the boiler body 2 is fixedly connected to a feed pipe 103 by bolts.

The first lifting frame 3 and the second lifting frame 4 are both movably connected to the plurality of ear plates. The structure of the second lifting frame 4 is the same as that of the first lifting frame 3. The first lifting frame 3 includes a wire Rod 301, slide rod 302 and servo motor 303, servo motor 303 is fixedly connected to the bottom end of screw rod 301, screw rod 301 and slide rod 302 are both located on the same side of conveying box 1, screw rod 301 is threadedly connected to the ear plate on one side of conveying box 1, slide rod 302 is through-connected to the other ear plate on one side of conveying box 1, a seat box 5 is provided at the bottom of conveying box 1, the bottom end of slide rod 302 is fixedly connected to the top of seat box 5, the bottom end of screw rod 301 is through-connected to the top of seat box 5, and servo motor 303 is fixedly connected inside seat box 5.

[0030] During use, when the bottom end of the boiler body 2 needs maintenance, the staff uses tools to remove the bolts on the feed pipe 103 to cancel the fixed connection between the conveying box 1 and the boiler body 2, and then starts the first lifting frame 3 and the second lifting frame 4. The servo motor 303 runs to drive the screw rod 301 to rotate, and the screw rod 301 drives the conveying box 1 to slide downward, so that the conveying box 1 is located on the top of the seat box 5, and the conveying box 1 is away from the slag discharge port of the boiler body 2. The slide rod 302 cooperates with the screw rod 301 to limit the two sides of one end of the conveying box 1. At the same time, the first lifting frame 3 and the second lifting frame 4 keep the overall device of the conveying box 1 stable, avoid imbalance at both ends of the conveying device affecting the lifting, and facilitate the staff to perform regular maintenance on the boiler body 2.

[0031] In this embodiment, the first lifting frame 3 and the second lifting frame 4 are respectively located on both sides of the conveying box 1, and a number of square grooves 501 are respectively opened on both sides of the outside of the seat box 5. The inner wall of the square groove 501 is opened with sliding grooves 502 twice, and a number of limit rods 503 are provided inside the sliding groove 502. A drawer 6 is provided between the screw rod 301 and the sliding rod 302, and the drawer 6 is slidably connected to the inside of the square groove 501.

[0032] During use, when the automatic conveying device breaks down and needs maintenance, the staff pulls out the drawers 6 on both sides of the seat box 5, and the slides 601 on both sides are subjected to force, driving the drawers 6 to slide in the slide groove 502, so that the drawers 6 move out of the square groove 501, and the limit rod 503 limits the slide groove 502 to prevent the slide 601 from derailing during the movement of the drawer 6, causing the drawer 6 to fall and affect the storage use.

[0033] In this embodiment, slides 601 are fixedly connected on both sides of the tail end of the square groove 501, and slides 601 are fixedly connected on both sides of the tail end of the square groove 501. The slides 601 are located in the slide 502, and both ends of the limit rod 503 pass through the slide 601 and are fixedly connected to the inner wall of the slide 502. The conveying box 1 includes an auger 101, a drive motor 102 and a discharge pipe 104. The two ends of the auger 101 are rotatably connected to both sides of the inner wall of the conveying box 1.

[0034] When in use, the drawer 6 has a large internal space and a storage function, which makes it convenient for the staff to place maintenance tools and parts in the drawer 6 for storage, avoiding the staff from wasting time looking for maintenance tools and affecting the efficiency of automatic transportation and screening of waste slag.

[0035] In this embodiment, the drive motor 102 is fixedly connected to the outer side panel of the conveying box 1, the output of the drive motor 102 passes through the conveying box 1 and is fixedly connected to the shaft at one end of the auger 101, the discharge pipe 104 is connected to the bottom of the tail end of the conveying box 1, and a screening box 7 is provided at the bottom of the conveying box 1. The top of the screening box 7 is fixedly connected to the cloth tube 702 by bolts, and the top of the cloth tube 702 is fixedly connected to the bottom of the discharge pipe 104 by bolts.

[0036] During use, the waste slag inside the boiler body 2 enters the conveying box 1 through the feed pipe 103, and the output end of the driving motor 102 drives the auger 101 to rotate, so that the waste slag follows the auger 101 to flip and move to the discharge pipe 104, and the waste slag enters the screening box 7 through the cloth tube 702. The cloth tube 702 blocks the dust generated by the waste slag discharge, preventing the dust generated by the waste slag discharge from diffusing into the air and reducing the air quality of the power plant workshop.

[0037] In this embodiment, the screening box 7 includes a vibrating screen plate 703, a baffle 704 and a discharge pipe 705. The vibrating screen plate 703 is fixedly connected to the inside of the screening box 7 at an angle. Several baffles 704 are fixedly connected to the top of the lowest end of the vibrating screen plate 703. The top of the baffle 704 is fixedly connected to the top of the screen box 7. The outer side of the screening box 7 is in contact with the side of the seat box 5. The side of the screening box 7 away from the seat box 5 is fixedly connected with the discharge pipe 705. The discharge pipe 705 is located on the side of the vibrating screen plate 703 and the baffle 704.

[0038] When in use, a cloth tube 702 is connected between the screening box 7 and the conveying box 1. The cloth tube 702 includes a top plate, a bottom plate and a cloth pipe. The cloth pipe is fixedly connected between the top plate and the bottom plate. The cloth pipe is formed by sewing cloth into a tubular shape and has folding and stretching properties. When the conveying box 1 is driven downward by the first lifting frame 3 and the second lifting frame 4, the discharge pipe 104 of the conveying box 1 presses down the cloth tube 702, and the cloth pipe folds, so that the top plate and the bottom plate of the cloth tube 702 are close to each other, which facilitates the up and down movement of the conveying box 1 and avoids the fixed volume of the cloth tube 702 affecting the lifting and lowering of the conveying box 1.

[0039] In this embodiment, a limit frame 706 is provided at the bottom of the vibrating screen plate 703, and the limit frame 706 is fixedly connected to the inner wall of the screening box 7. A vibration motor 707 is fixedly connected to the outer side of the screening box 7. A placement groove 701 is provided on the side of the screening box 7 close to the vibration motor 707. The placement groove 701 is located at the bottom of the limit frame 706, and the material receiving box 8 is movably connected inside the placement groove 701.

[0040] During use, the blocky waste residue is moved out of the discharge pipe 705 and into the collection box 9 due to the inclined guide sliding of the vibrating screen plate 703, so that the waste residue is automatically transported and then automatically screened, avoiding the time and manpower consumption of the staff in carrying and screening again.

[0041] In this embodiment, the bottom of the limit frame 706 is fittedly connected to the top of the material receiving box 8, the bottom of the screening box 7 is fixedly connected to the base 10, a collecting box 9 is provided on one side of the base 10, the collecting box 9 is located at the bottom of the discharge pipe 705, and an electronic scale 11 is fixedly connected to one side of the top of the base 10. The electronic scale 11 is located inside the placement slot 701, and the material receiving box 8 is slidably connected to the top of the electronic scale 11.

[0042] During use, the staff starts the vibration motor 707 through the electrical control box 12. The vibration motor 707 runs, and the vibrating screen plate 703 vibrates to screen the falling waste residue. The dust inside the waste residue falls into the material receiving box 8 through the vibrating screen plate 703 and is stored. The material receiving box 8 is located on the top of the electronic scale 11, which is convenient for weighing and recording the screened dust.

[0043] In this embodiment, a support frame 1001 is fixedly connected to the top of the base 10, and the top of the support frame 1001 is fixedly connected to the bottom of the seat box 5. An electric control box 12 is provided on one side of the support frame 1001, and the electric control box 12 is fixedly connected to one side of the top of the base 10. Several cylinder supports 13 are provided on both sides of the outside of the electric control box 12. The cylinder supports 13 are fixedly connected to the top of the base 10, and several universal wheels 14 are fixedly connected to the bottom of the base 10.

[0044] When in use, the staff controls the overall electric structure of the automatic conveying device through the electrical control box 12, starts the cylinder support 13, and the telescopic end of the cylinder support 13 rises away from the ground, so that the base 10 is released from the fixed connection. The staff pushes the automatic conveying device, and the universal wheel 14 drives the automatic conveying device to move away from the boiler body 2, which facilitates the displacement of the automatic conveying device and is conducive to separating the automatic conveying device from the boiler body 2 for maintenance and inspection.

[0045] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when the bottom end of the boiler body 2 needs to be maintained, the staff uses tools to remove the bolts on the feed pipe 103 to cancel the fixed connection between the conveying box 1 and the boiler body 2, and then starts the first lifting frame 3 and the second lifting frame 4. The servo motor 303 runs to drive the screw rod 301 to rotate, and the screw rod 301 drives the conveying box 1 to slide downward, so that the conveying box 1 is located on the top of the seat box 5, and the conveying box 1 is away from the slag discharge port of the boiler body 2. The slide rod 302 cooperates with the screw rod 301 to limit the two sides of one end of the conveying box 1. At the same time, the first lifting frame 3 and the second lifting frame 4 are started. The frame 3 and the second lifting frame 4 keep the overall device of the conveying box 1 stable, avoid the imbalance of the two ends of the conveying device affecting the lifting, and facilitate the staff to perform regular maintenance on the boiler body 2. The waste slag inside the boiler body 2 enters the conveying box 1 through the feeding pipe 103, and the output end of the driving motor 102 drives the auger 101 to rotate, so that the waste slag follows the auger 101 to flip and move to the discharge pipe 104. The waste slag passes through the cloth tube 702 and enters the screening box 7. The staff starts the vibration motor 707 through the electric control box 12. The vibration motor 707 runs, and the vibration screen plate 703 vibrates to screen the falling waste slag. The dust falls into the collecting box 8 through the vibrating screen plate 703 and is stored. The collecting box 8 is located on the top of the electronic scale 11, which is convenient for weighing and recording the screened dust. The blocky waste slag slides out of the discharge pipe 705 and enters the collection box 9 due to the inclined guide of the vibrating screen plate 703, so that the waste slag can be automatically transported and then automatically screened, avoiding the time and manpower consumption of the staff for carrying and screening again, and at the same time avoiding the dust generated by the waste slag from spreading in the air, reducing the air quality of the power plant workshop. When the automatic conveying device fails and needs maintenance, the staff pulls out the drawers 6 on both sides of the seat box 5 to move the drawers 6 out of the square slot 501. The drawer 6 has a storage function, which is convenient for storing maintenance tools and spare parts, avoiding the staff from wasting time looking for maintenance tools, which affects the efficiency of automatic transportation and screening of waste slag. The staff controls the overall electric structure of the automatic conveying device through the electric control box 12, starts the cylinder support 13, and the telescopic end of the cylinder support 13 rises away from the ground, so that the base 10 is released from the fixed connection. The staff pushes the automatic conveying device, and the universal wheel 14 drives the automatic conveying device to move away from the boiler body 2, which facilitates the displacement of the automatic conveying device and is conducive to the separation of the automatic conveying device and the boiler body 2 for maintenance and inspection.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
