Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomass pyrolysis toner sorting technology, and in particular to a toner slurry sorting device. Background Technology
[0002] In the process of biomass pyrolysis to form carbon powder, due to differences in biomass sources and human factors, biomass often contains sediment and other sludge. Simultaneously, variations in biomass pyrolysis technology result in different oxygen contents in the furnace, leading to varying amounts of ash in the produced carbon powder. Traditional methods for separating carbon powder, sediment, and ash involve direct sieving using a filter screen. However, due to the different properties and particle sizes of sediment and ash, multiple sieving processes are required, which is labor-intensive and results in a low net carbon powder content. Therefore, there is an urgent need for equipment capable of separating carbon powder, sediment, and ash. Summary of the Invention
[0003] To address the problems of high workload and difficulty in screening toner using existing filters, this invention provides a toner slurry separation device. By installing two vortex-generating pipes in the lower part of the flotation tower, the toner slurry entering the tower body forms a vortex. An air blowing device then raises the vortexed slurry to an ultrasonic oscillating washer, where ultrasonic oscillation separates the toner slurry into toner, sediment, and ash, reducing workload.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A toner slurry separation device includes a flotation tower body. A vortex-generating pipe is installed at the lower part of the flotation tower body to allow the toner slurry to enter the interior of the flotation tower body, and the vortex-generating pipe is connected to the flotation tower body. An air blowing device is installed inside the flotation tower body to blow the toner slurry upwards, and a separation device for separating the toner slurry is installed above the air blowing device. A toner collection tank is installed inside the flotation tower body. The air blowing device and the separation device are fitted onto the outside of the toner collection tank. An ash collection device is also installed at the upper part of the flotation tower body. An exhaust port is opened at the top of the flotation tower body. A sludge discharge port is opened at the bottom of the flotation tower body.
[0005] Furthermore, there are two vortex-generating tubes, both with their inlet ends fitted into the side wall of the flotation tower body. This fitted arrangement of the two vortex-generating tubes against the side wall of the flotation tower body causes the carbon powder slurry entering the tower body to flow against the inner wall. The two streams of carbon powder slurry flowing against the inner wall form vortices under the action of impact and centrifugal force. These vortices facilitate gas-liquid mixing and flotation separation, making it easier to separate materials of different densities under centrifugal force.
[0006] Furthermore, the air blowing device includes an air distribution pipe and an air injection port. The air distribution pipe is annular and fixed inside the flotation tower body, with multiple air holes at its top. The air injection port is fixed outside the flotation tower body and passes through the flotation tower body, connecting to the air distribution pipe. The arrangement of the air distribution pipe and the air injection port allows the carbon powder slurry entering the flotation tower body to rise to the separation device under the blowing of gas.
[0007] Furthermore, the air blowing device also includes a second air distribution pipe and a second air injection port. The second air distribution pipe has the same structure as the first air distribution pipe and is located at the separation device. The second air injection port is fixed to the outside of the flotation tower body and passes through the flotation tower body, connecting with the second air distribution pipe. Through the second air distribution pipe and the second air injection port, the carbon powder and ash residue separated by oscillation rise upwards. The carbon powder enters the carbon powder collection tank, while the lighter ash residue is discharged from the ash residue discharge port after passing through the ash residue funnel.
[0008] Furthermore, the separation device includes an ultrasonic vibrating scrubber and a ring vibrator. The ultrasonic vibrating scrubber is located outside the flotation tower body and is fixedly connected to the ring vibrator, which is located inside the flotation tower body and fitted onto the outside of the toner collection tank. An ultrasonic transducer connects to the ring vibrator, transmitting the mechanical vibration generated by the transducer to the ring vibrator. The ring vibrator oscillates the rising toner slurry, separating the sludge, toner, and ash.
[0009] Furthermore, the upper part of the toner collection bucket has a mesh structure, and the lower part has a conical structure formed by solid sheets. The mesh structure at the top of the toner collection bucket can filter out toner slurry or ash residue that accidentally enters the toner collection bucket.
[0010] Furthermore, the flotation tower body is fixedly connected to a toner discharge port, which passes through the flotation tower body and communicates with the bottom of the toner collection tank; the toner discharge port is also connected to a pneumatic pump for extracting the filtered toner. The toner discharge port and pneumatic pump facilitate the extraction of toner collected in the toner collection tank.
[0011] Furthermore, the ash collection device includes an ash funnel and an ash discharge port. The ash funnel is located on the upper part of the carbon powder collection tank, and the ash discharge port is located at the connection between the ash funnel and the flotation tower body. By installing the ash collection device on the upper part of the flotation tower body, according to the principle of air flotation, as the liquid level in the flotation tower body increases, the ash floating on the air bubbles rises to the top of the ash funnel. The ash then flows with the air bubbles to the side wall of the ash funnel and is discharged from the ash discharge port.
[0012] Furthermore, a filter is connected to the exhaust port, and the filter is connected to the first and / or second air injection port via a pipe. The filter at the exhaust port filters out water vapor and impurities in the discharged gas, and the filtered gas is recycled through the pipe into the first and / or second air injection port.
[0013] The beneficial effects of this utility model through the above technical solution are: This invention separates the carbon powder slurry entering the flotation tower into sludge, carbon powder, and ash by installing an air blowing device and a separation device inside the tower body. Furthermore, by installing two vortex-generating pipes at the bottom of the tower body, this invention creates vortices in the carbon powder slurry entering the tower, which facilitates gas-liquid mixing and flotation, making it easier to separate materials of different densities under centrifugal force.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-5 As shown, a carbon powder slurry separation device includes a flotation tower body 1, which is a hollow cylindrical structure and has an inverted conical structure at the bottom; an exhaust port 4 is provided at the top of the flotation tower body 1 and a sludge discharge port 5 is provided at the bottom of the flotation tower body 1.
[0021] The lower part of the flotation tower body 1 is provided with vortex-generating tubes 2 to allow carbon powder slurry to enter the interior of the flotation tower body 1. In this embodiment, there are two vortex-generating tubes 2, which are centrally symmetrically arranged on both sides of the lower part of the flotation tower body 1. The inlet end of the vortex-generating tube 2 is connected to the flotation tower body 1 and is attached to the inner wall of the flotation tower body 1. The vortex-generating tube 2 is tangent to the flotation tower body 1. When the carbon powder slurry enters the interior of the flotation tower body 1 from the two vortex-generating tubes 2, the two streams of carbon powder slurry flow against the inner wall of the flotation tower body 1 and then merge. Under the action of impact force and centrifugal force, they merge to form a vortex. The vortex helps the gas-liquid mixture to float, and materials of different densities are more easily separated under the action of centrifugal force.
[0022] The flotation tower body 1 is equipped with an upward-flowing air blowing device for agitating the carbon powder slurry. This air blowing device is located below the vortex-generating tube 2 and includes an air distribution pipe 6 and an air injection port 7. The air distribution pipe 6 has an annular structure with multiple circumferential air holes at its top. The air distribution pipe 6 is located inside the flotation tower body 1, while the air injection port 7 is fixed to the outside of the flotation tower body 1. The air injection port 7 is located below the vortex-generating tube 2 and passes through the flotation tower body 1, communicating with the air distribution pipe 6. The arrangement of the air distribution pipe 6 and the air injection port 7 causes the carbon powder slurry entering the flotation tower body 1 to rise under the agitation of the gas.
[0023] Above the blowing device is a sorting device for separating carbon powder slurry. This sorting device includes an ultrasonic oscillating washer 10 and a ring oscillator 11. The ultrasonic oscillating washer 10 is located outside the flotation tower body 1. The ultrasonic oscillating washer 10 includes an ultrasonic generator, an ultrasonic transducer, and a control system. The ultrasonic generator and the ultrasonic transducer are electrically connected. The ultrasonic generator, also known as an ultrasonic power supply, drives the ultrasonic transducer. The ultrasonic transducer converts the high-frequency signal generated by the ultrasonic generator into mechanical vibration energy. The control system controls and adjusts the frequency and power of the ultrasonic generator and the ultrasonic transducer. The ultrasonic generator, ultrasonic transducer, and control system in this embodiment are all existing technologies and will not be described in detail.
[0024] The annular oscillator 11 is fixedly connected to the ultrasonic transducer. In this embodiment, there are two ultrasonic transducers, and each of the two ultrasonic transducers is fixedly connected to the annular oscillator 11. The annular oscillator 11 is an annular stainless steel ring. The two annular oscillators 11 are located in the middle of the flotation tower body 1. The annular oscillators are connected to the ultrasonic transducers so that the mechanical vibration generated by the ultrasonic transducers is transmitted to the annular oscillators 11. The annular oscillators 11 oscillate and separate the rising carbon powder slurry into sludge, carbon powder and ash.
[0025] The flotation tower body 1 is equipped with a carbon powder collection tank 3 inside, and the gas distribution pipe 6 and the annular oscillator 11 are both fitted onto the outside of the carbon powder collection tank 3. The carbon powder collection tank 3 has a mesh structure, and the lower part is a conical structure formed by solid sheets. A carbon powder discharge port 12 is fixedly connected to the lower part of the flotation tower body 1, and the carbon powder discharge port 12 passes through the flotation tower body 1 and communicates with the bottom of the carbon powder collection tank 3.
[0026] A slag collection device is also provided on the upper part of the flotation tower body 1. The slag collection device includes an slag funnel 14 and an slag discharge port 15. The slag funnel 14 is located on the upper part of the carbon powder collection tank 3 and is fixedly connected to the flotation tower body 1. The sidewall of the slag funnel 14 has a mesh structure, and the pore size of the mesh on the sidewall of the slag funnel 14 is smaller than the diameter of the carbon powder. The slag discharge port 15 is located at the lower part of the slag funnel 14 where it connects to the flotation tower body 1.
[0027] To further improve the separation and toner slurry flow effect, the air blowing device also includes a second air distribution pipe 8 and a second air injection port 9. The second air distribution pipe 8 has the same structure as the first air distribution pipe 6, and is located between the two annular oscillators 11. The second air distribution pipe 8 is fitted onto the outside of the toner collection tank 3. The second air injection port 9 is fixed to the outside of the flotation tower body 1, and passes through the flotation tower body 1 to communicate with the second air distribution pipe 8. In this embodiment, both the first air injection port 7 and the second air injection port 9 are connected to an external air source to inject air or nitrogen into the first air injection port 7 and the second air injection port 9.
[0028] A filter 16 is connected to the exhaust port 4. The filter 16 is connected to the first air injection port 7 and / or the second air injection port 9 through a pipe. After the exhaust port 4 discharges impurities from the gas through the filter 16, it enters the first air injection port 7 and / or the second air injection port 9 through the pipe for recycling.
[0029] When in use, unsorted carbon powder is mixed with water and ground to form a carbon powder slurry. The grinding process changes the surface properties of the carbon powder, making it more hydrophilic. The carbon powder slurry is injected into the flotation tower body 1 through the vortex-generating pipe 2. The two streams of carbon powder slurry flow along the inner wall of the flotation tower body 1 and then merge. Under the action of impact and centrifugal force, they merge to form a vortex. At the same time, the gas injection port-7 is connected to an external gas source and delivers gas to the gas distribution pipe-6. The gas ejected from the gas hole blows the carbon powder slurry formed by the vortex upward from the bottom of the vortex. Under the action of centrifugal force and impact force, it spirals upward to the separation device. The mechanical vibration generated by the ultrasonic transducer of the ultrasonic oscillating scrubber 10 of the separation device is transmitted to the annular oscillator 11. The annular oscillator 11 oscillates and separates the rising carbon powder slurry into sludge, carbon powder, and ash.
[0030] Because the sludge is denser than water, it sinks to the bottom of the flotation tower body 1 and is discharged from the sludge discharge port 5. The carbon powder collecting tank 3 collects the carbon powder floating on the liquid surface, while the lighter ash forms foamy scum that floats on top of the carbon powder layer. At this point, increasing the carbon powder slurry flow rate at the vortex generator 2 raises the liquid level inside the flotation tower body 1. When the foamy scum is higher than the ash funnel opening 14, the foamy scum formed by the ash flows to both sides of the ash funnel opening 14 and is discharged from the ash discharge port 15. After collecting the carbon powder floating on the liquid surface, the carbon powder in the carbon powder collecting tank 3 is extracted from the bottom of the carbon powder collecting tank 3 by the pneumatic pump 13.
[0031] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
