Description

Technical Field

[0001] This utility model relates to the field of waste incineration slag treatment technology, specifically to a multi-stage buoyancy sorting device for waste incineration slag. Background Technology

[0002] Waste incineration is the process by which waste is reduced in volume through appropriate thermal decomposition, combustion, and melting reactions at high temperatures, turning it into residue or molten solid matter. Incineration residue is the general term for slag, leaked ash, boiler ash, and fly ash produced during waste incineration. In the process of treating waste incineration slag, it is usually necessary to sort it, with buoyancy-based sorting being the most commonly used technique.

[0003] Currently, when performing buoyancy separation of waste incinerator slag, aeration is usually carried out in the flotation tank. The aeration bubbles come into contact with the mineral particles, allowing the hydrophobic slag particles to float with the bubbles. However, since the direction of the air holes on the aeration pipe is often fixed, the direction range of the air jet is also fixed. Due to the existence of many dead zones, it is difficult to fully and effectively contact the slag in the water, which greatly affects the flotation efficiency of the slag and results in poor performance. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage buoyancy separation device for waste incineration slag. By setting up a loop-shaped pipeline on the flotation tank, multiple sets of aeration units are distributed along the loop-shaped pipeline. Each aeration unit consists of an air collecting cylinder, a jet pipe, a movable seat, and a connecting arm. With the help of a drive assembly, the multiple jet pipes on the air collecting cylinder can be controlled to simultaneously close inward or open outward. Air is then introduced into each air collecting cylinder through the loop-shaped pipeline and branch pipes. Afterward, air can be ejected from each jet pipe through a telescopic hose. With the cooperation of multiple aeration units, air can be evenly distributed throughout the water, allowing particles in the water to fully contact the aeration bubbles and float upward, greatly improving the flotation efficiency of the slag and achieving good results, thus overcoming the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage buoyancy sorting device for waste incineration slag, comprising:

[0006] A flotation tank, wherein a discharge pipe is provided in the middle of the bottom side of the flotation tank, and a loop pipe is provided on the outside of the flotation tank. One end of the loop pipe is connected to an air pump through a pipe, and multiple air ventilation units are provided on the side wall of the loop pipe.

[0007] A screening frame is located at the bottom of the flotation box near the discharge pipe, and a sieve plate is provided at the top of the screening frame. A conveyor belt is provided on one side of the screening frame near the bottom of the sieve plate.

[0008] The ventilation unit includes a branch pipe located inside the loop-shaped pipeline. One end of the branch pipe extends into the flotation tank and is connected to a gas collecting cylinder. Multiple fixing brackets are fixed in a circular array on the side wall of the gas collecting cylinder. An air jet pipe is rotatably connected to the end of each fixing bracket via a rotating shaft. A telescopic hose is connected between one end of the air jet pipe and the gas collecting cylinder, and a fixing sleeve is provided on the outer wall of the other end of the air jet pipe. A drive assembly is located in the middle of the side wall of the gas collecting cylinder between the multiple air jet pipes. A movable seat is connected to the output end of the drive assembly. A connecting arm is rotatably connected to each of the movable seat and the multiple fixing sleeves via a rotating shaft.

[0009] Preferably, a vibration motor is provided at one end of the screening frame, and a connecting block is connected to the output end of the vibration motor, and the connecting block is fixedly connected to the sieve plate.

[0010] Preferably, a drain pipe is provided at the bottom of the screening frame, and a water supply pipe is provided at the top of the flotation box.

[0013] Preferably, an electric push rod is provided on one side of the top of the flotation tank, and the output end of the electric push rod extends into the flotation tank and is provided with a push plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] By installing a loop-shaped pipeline on the flotation tank, multiple sets of aeration units are distributed on the loop-shaped pipeline. The aeration unit consists of a gas collecting cylinder, a jet pipe, a movable seat, and a connecting arm. With the help of the drive assembly, the multiple sets of jet pipes on the gas collecting cylinder can be controlled to synchronously close inward or open outward. Air is introduced into each gas collecting cylinder through the loop-shaped pipeline and branch pipes. Then, the air can be ejected from each jet pipe through the telescopic hose.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-4 The waste incinerator ash buoyancy multi-stage sorting device shown includes:

[0025] Flotation box 1, with a discharge pipe 3 in the middle of the bottom side of flotation box 1, and a loop pipe 10 on the outside of flotation box 1. One end of the loop pipe 10 is connected to an air pump 11 through a pipe, and multiple ventilation units 12 are provided on the side wall of the loop pipe 10.

[0026] A drain pipe 2 is installed on one side of the flotation tank 1, near the bottom of the loop pipe 10.

[0027] Screening frame 4 is located at the bottom of flotation box 1 near the discharge pipe 3, and a screen plate 6 is provided at the top of the screening frame 4. A conveyor belt 7 is provided on one side of the screening frame 4 near the bottom of the screen plate 6.

[0028] A vibration motor 22 is provided at one end of the screening box 4. A connecting block 23 is connected to the output end of the vibration motor 22. The connecting block 23 is fixedly connected to the sieve plate 6.

[0029] A drain pipe 5 is installed at the bottom of the screening box 4, and a water supply pipe is installed at the top of the flotation box 1.

[0030] An electric push rod 8 is provided on one side of the top of the flotation tank 1. The output end of the electric push rod 8 extends into the flotation tank 1 and is provided with a push plate 9.

[0031] When in use, the slag can be poured into the flotation box 1. At this time, some of the slag falls to the bottom of the flotation box 1 due to gravity, while the lighter slag can float on the water surface of the flotation box 1. After the slag has completely settled and floated and separated, the staff can scoop out the floating slag. The push plate 9 can be moved by the electric push rod 8, so that the push plate 9 can concentrate the floating slag in one place for scooping.

[0032] Furthermore, water can be discharged from the flotation box 1 through the drain pipe 2, and then the discharge pipe 3 can be opened through the control valve to discharge the slag at the bottom and let it fall into the screening frame 4, thereby quickly realizing the buoyancy separation of slag.

[0033] Afterwards, the slag can fall onto the screen plate 6 inside the screening frame 4. With the help of the vibration motor 22 and the connecting block 23, the screen plate 6 can be driven to vibrate, so that the slag can roll down along the screen plate 6 onto the conveyor belt 7. In this process, the residual moisture and sand on the slag can be shaken off to the bottom of the screening frame 4 for further sorting, which has a better effect.

[0034] The ventilation unit 12 includes a branch pipe 120 disposed inside the loop pipe 10. One end of the branch pipe 120 extends into the flotation tank 1 and is connected to a gas collecting cylinder 13. Multiple fixing brackets 17 are fixed in a ring array on the side wall of the gas collecting cylinder 13. The end of the fixing bracket 17 is rotatably connected to a jet pipe 19 via a rotating shaft. A telescopic hose 18 is connected between one end of the jet pipe 19 and the gas collecting cylinder 13, and a fixing sleeve 20 is provided on the outer wall of the other end of the jet pipe 19. A drive assembly is disposed in the middle of the side wall of the gas collecting cylinder 13 between the multiple jet pipes 19. The output end of the drive assembly is connected to a movable seat 16. A connecting arm 21 is rotatably connected between the movable seat 16 and the multiple fixing sleeves 20 via a rotating shaft.

[0035] The drive assembly includes a sealing cover 14 disposed on the air collection cylinder 13. A miniature cylinder 15 is embedded inside the sealing cover 14. The output end of the miniature cylinder 15 extends outside the sealing cover 14 and is fixedly connected to the movable seat 16.

[0036] In use, the air pump 11 can be started to supply air into the loop pipe 10. Then, the loop pipe 10 can supply air into each gas collecting cylinder 13 through the branch pipe 120. After that, the air can enter each jet pipe 19 through the telescopic hose 18. By starting the micro cylinder 15, the micro cylinder 15 can drive the movable seat 16 to move. Then, the movable seat 16 can drive multiple synchronous rotations, so that the connecting arm 21 drives the jet pipe 19 to rotate through the fixed sleeve 20. This can control the multiple sets of jet pipes 19 on the gas collecting cylinder 13 to synchronously close inward or open outward. With the cooperation of multiple sets of aeration units 12, air can be evenly supplied to all parts of the water, so that the particles in the water can fully contact the aeration bubbles and float up, which greatly improves the flotation efficiency of slag and has a good effect.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
