Description

Technical Field

[0001] This utility model relates to a processing device, and more particularly to a slag water quenching processing device. Background Technology

[0002] Fly ash produced during waste incineration contains a large amount of harmful substances, which will cause serious environmental pollution if not treated. Electric furnace melting is an important method for treating fly ash from waste incineration. The fly ash is heated to above 1100℃ in the electric furnace to form liquid slag, thereby removing the harmful substances. The slag after the fly ash is melted must be rapidly cooled through processes such as water quenching.

[0003] However, while the existing technology for collecting molten slag by water quenching can collect the slag after cooling, it still has the following drawbacks: single-layer water spraying leads to uneven cooling of the slag, low granulation rate, poor water quenching effect, and cannot meet the application requirements.

[0004] Therefore, it is necessary to develop a new type of slag water quenching treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a slag water quenching treatment device.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a slag water quenching treatment device, comprising:

[0007] A guide channel for guiding molten slag is inclined and has a downward-facing horizontal outlet at its end.

[0008] The water quenching chamber has a reaction cylinder installed at an incline inside. A slag inlet adapted to the horizontal outlet is formed on the reaction cylinder, and its end passes through the chamber to form a discharge outlet.

[0010] A vibration mechanism connected to the reaction cylinder includes a swing block. One end of the swing block is movably connected to the reaction cylinder through a connecting cover, and the other end is connected to a transmission mechanism. The vibration mechanism drives the reaction cylinder to swing horizontally.

[0011] The slag collection hopper is located below the discharge outlet.

[0012] Preferably, the transmission mechanism includes a motor, the output shaft of which is connected to a rotating handle, and the other end of the rotating handle is connected to a swinging member via a connecting rod.

A rotating shaft is provided between the limiting block and the transmission rod. A toggle block is provided on the top surface of the rotating shaft. The toggle block is movably connected to the swinging block.

[0014] Preferably, the swing block has an elongated groove with an opening facing downwards, and the top of the actuating block has a slider that cooperates with the elongated groove. The slider can slide along the elongated groove and drive the swing block to swing back and forth.

[0015] Preferably, a hollow groove is formed on the transmission rod, and a fixing block is provided in the hollow groove, which is movably connected to the connecting rod.

[0016] Preferably, the connecting cover is cylindrical, which is fitted outside the reaction cylinder and fastened to it, and the swing block is connected to the connecting cover through a rotating shaft.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-3 The slag water quenching treatment apparatus shown includes:

[0027] The guide channel 1 is used for guiding the molten slag. The guide channel 1 is set at an inclination and has a horizontal outlet 11 with an opening facing downward at its end.

[0028] The guide channel 1 has an inclination angle of 25-40°, and an electric regulating valve for controlling the molten slag flow rate is installed at the end of the guide channel 1; a vibration motor is installed at the bottom of the guide channel 1, with a vibration frequency of 20-50Hz to prevent molten slag adhesion. By setting the inclined guide channel, it is beneficial to vibrate and disperse the high-temperature molten slag, and the flow rate of the molten slag can be controlled by setting the electric regulating valve.

[0029] By setting a horizontal outlet and creating a slag inlet on the surface of the reaction cylinder that matches the horizontal outlet, the slag in the guide channel can directly enter the reaction cylinder, facilitating subsequent cooling of the slag. The outer wall of guide channel 1 is equipped with a water-cooled jacket, using circulating water to pre-cool the slag to 1000-1200℃, reducing the amount of spray water required. The inner wall of guide channel 1 is lined with a 5-10mm thick high-temperature resistant silicon carbide ceramic layer. The silicon carbide ceramic layer has a thickness of 8-15mm and a temperature resistance ≥1600℃, thus extending its service life.

[0030] The water quenching chamber 2 has a reaction cylinder 21 installed at an incline inside. The reaction cylinder 21 has a slag inlet that is adapted to the horizontal outlet, and its end passes through the chamber to form a discharge outlet. The end of the reaction cylinder extends out of the water quenching chamber to facilitate the collection of slag.

[0031] An inclined reaction cylinder is installed inside the water quenching tank, which allows the molten slag to quickly enter the slag collection hopper under the action of gravity, which is beneficial for slag collection.

[0032] The multi-layer water spray pipes 9 are located inside the reaction cylinder. Each layer of water spray pipes 9 is arranged in a ring array. The direction of water spraying is at a 45-90° angle to the direction of molten slag falling. Each layer of water spray pipes 9 is connected to 12-24 atomizing nozzles.

[0033] By setting multiple layers of water spray pipes inside the reaction cylinder, with the water spray direction forming an angle opposite to the direction of molten slag falling, a cross water curtain is formed, avoiding uneven slag cooling caused by single-layer water spray, and enhancing the granulation rate and water quenching effect.

[0034] The vibration mechanism 3 is connected to the reaction cylinder. The vibration mechanism 3 includes a swing block 31. One end of the swing block 31 is movably connected to the reaction cylinder through the connecting cover 5, and the other end is connected to the transmission mechanism 6. The vibration mechanism drives the reaction cylinder to swing horizontally.

[0035] To enhance the water quenching effect within the reaction cylinder, the reaction cylinder is connected to a vibration mechanism. This allows the vibration mechanism to drive the reaction cylinder to vibrate, preventing slag adhesion while simultaneously enhancing the water quenching effect. Specifically, the end of the reaction cylinder is connected to a connecting cover, which in turn causes the reaction cylinder to oscillate. One end of a swing block is connected to the connecting cover, and the other end is connected to a transmission mechanism. The transmission mechanism then drives the swing block to rotate, which in turn causes the connecting cover to rotate.

[0036] Specifically, the transmission mechanism 6 includes a motor 61, the output shaft of which is connected to a rotating handle 62. The other end of the rotating handle 62 is connected to the swing member 8 via a connecting rod 63. The swing member 8 is movably connected to the swing block 31 and drives it to rotate.

[0037] The motor is installed inside the water quenching chamber. When the motor is started, it drives the rotating handle to rotate. The rotation of the rotating handle drives the connecting rod to reciprocate. The other end of the connecting rod is connected to the swinging component. Therefore, the swinging component swings back and forth under the drive of the connecting rod, which in turn drives the swinging block to swing.

[0038] Preferably, the swing member 8 includes a swing base 81 and a toggle block 82. The swing base 81 includes an upper limiting block 811 and a lower transmission rod 812. A rotating shaft 83 is provided between the limiting block 811 and the transmission rod 812. The top surface of the rotating shaft 83 is provided with a toggle block 82, and the toggle block 82 is movably connected to the swing block 31.

[0039] The swing component includes a swing base and a toggle block. The upper limit block of the swing base serves to limit the swing block, and the lower transmission rod serves to drive the linkage. A rotating shaft is provided between the limit block and the transmission rod, allowing the swing component to swing as a whole. The toggle block is in contact with the limit block and is located on the top surface of the rotating shaft. Therefore, the rotation of the rotating shaft can drive the toggle block to swing back and forth, and further drive the swing block to rotate through the toggle block.

[0040] Specifically, the top surface of the limiting block 811 is recessed downward to form an arc-shaped groove, and its two ends form symmetrical arc-shaped surfaces. The swing block is trident-shaped, with the middle fork movably connected to the actuating block. The other two forks are symmetrically formed on both sides of the middle fork. The edge of the swing block is arc-shaped to match the arc-shaped surface of the limiting block, so that the swing block can swing when the limiting block swings. The arc-shaped groove provides space for the swing of the middle fork. By setting the limiting block, the swing block can swing within a certain range, thereby controlling the swing amplitude of the swing block. The actuating block is an isosceles triangle. The center of the limiting block is tightly connected to the actuating block. The bottom surface of the actuating block is arc-shaped to match the top surface of the rotating shaft, so that it can move with the rotating shaft.

[0041] The specific working process is as follows: when the connecting rod drives the transmission rod to swing back and forth through the fixed block, since the fixed block is fixedly connected to the transmission rod and the transmission rod is equipped with a rotating shaft, the fixed block can drive the transmission rod to swing back and forth. Since the transmission rod and the limiting block are an integral structure, the limiting block and the actuating block swing together. During the swinging process of the limiting block and the actuating block, the slider at the top of the actuating block can slide along the long slide groove and slide into or out of the long slide groove. During this process, the slider drives the swinging block to swing back and forth, thereby realizing the shaking of the connecting cover.

[0042] Furthermore, an elongated groove 32 with an opening facing downwards is formed on the swing block 31, and a slider 821 that cooperates with the elongated groove is formed on the top of the actuating block 82. The slider 821 can slide along the elongated groove and drive the swing block to swing back and forth. By setting the elongated groove, the slider can slide along the elongated groove, and drive the swing block to swing back and forth during the sliding process.

[0043] Furthermore, a hollow groove is formed on the transmission rod 812, and a fixing block 813 is installed inside the hollow groove. The fixing block 813 is movably connected to the connecting rod 63. The swinging of the transmission rod drives the swinging seat to swing, which in turn drives the swinging block to swing.

[0044] To ensure the stability of the transmission mechanism, a fixed seat is provided on the rotating shaft, which is connected to the water quenching box. A fixed seat is also provided on the rotating shaft of the swing block, which is also connected to the water quenching box.

[0045] Specifically, the connecting cover 5 is cylindrical, which is fitted outside the reaction cylinder and fastened to it. The swing block 31 is connected to the connecting cover 5 through a rotating shaft.

[0046] By placing the connecting cover at the end of the reaction cylinder, the reaction cylinder shakes as the connecting cover rotates back and forth under the action of the swing block, thereby enhancing the water quenching effect and preventing slag from adhering to the bottom of the reaction cylinder.

[0047] The bottom of the reaction cylinder 21 is equipped with a support component, which includes three equally spaced support rods 7. Each support rod 7 has an annular clamp at its top, which fits and is fitted onto the outside of the reaction cylinder. The support rods provide support for the reaction cylinder and also ensure its stability.

[0048] The slag collection hopper 4 is located below the discharge outlet. Ultrasonic transducers with a frequency of 20-40kHz are installed on the side walls of the slag collection hopper to prevent slag particle caking. The slag collection hopper is connected to the spiral dewatering machine. The flushing water passes through a sedimentation tank → multi-stage filtration device (pore size ≤0.1mm) → plate heat exchanger → cooling tower, and is reused after the water temperature drops to 25-35℃. The subsequent processes for the slag collection hopper are existing technologies and will not be described further here.

[0049] The purpose of this utility model is to provide a slag water quenching treatment device. By setting multiple layers of reverse water spray pipes in the reaction cylinder for atomized spraying, the contact area with the slag is increased, the cooling rate of the slag is improved, and the granulation rate is high. At the same time, by setting a vibration mechanism, the reaction cylinder can swing, which further enhances the water quenching effect during the swinging process, thereby meeting the usage requirements.

[0050] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
