Description

Technical Field

[0001] This utility model relates to the field of coal powder separation technology, and in particular to a coal powder separation device in a coal powder mixture. Background Technology

[0002] During the coal charging process in a coke oven, high-pressure ammonia water needs to be turned on to ensure negative pressure suction and prevent smoke and dust from escaping into the environment. However, because the floating coal on top of the coal cake cannot be completely compacted, the coal dust on top of the coal cake will enter the gas purification section with the gas under the negative pressure generated by the high-pressure ammonia water.

[0003] The mixture of gas, ammonia, and pulverized coal from the coke oven undergoes a tar-ammonia separation process in the gas purification section. The ammonia is effectively separated, while the gas and partially separated pulverized coal continue flowing with the gas to the ammonium sulfate section. In the ammonium sulfate section, this pulverized coal mixes with the mother liquor, forming a pulverized coal mixture. This mixture then enters a settling tank for sedimentation, allowing the pulverized coal to settle naturally to the bottom. Next, workers manually scoop out the settled pulverized coal from the bottom of the tank – a time-consuming and labor-intensive process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a coal powder separation device in a coal powder mixture. The technical solution of this utility model is as follows:

[0007] Optionally, a support ring is fixedly connected to the inner side of the upper opening of the tank. The adsorption assembly includes a fixed plate and a support rod. The fixed plate is detachably connected to the support ring. The support rod is fixedly connected to the center of the lower surface of the fixed plate. Multiple adsorption plates are fixed to the outside of the support rod by two sets of fixing members. The two sets of fixing members are symmetrical to each other and distributed vertically.

[0008] Optionally, the upper surface of the support ring is provided with multiple sets of slots at equal intervals, and the lower surface edge of the fixing plate is provided with multiple sets of blocks at equal intervals. The multiple sets of blocks are respectively movably inserted into the slots at corresponding positions and the two are fixed together by bolts.

[0009] Optionally, the fastener includes two semi-circular buckles symmetrically arranged on the outside of the support rod. The two semi-circular buckles are interlocked and fixed together by bolts. The lower end of the semi-circular buckle is fixedly connected to a semi-cylinder. Multiple short columns are fixedly arranged circumferentially on the outer wall of the semi-cylinder.

[0014] The beneficial effects of this utility model through the above solution are as follows:

[0015] 1. In this invention, the pulverized coal mixture first enters the tank body from the buffer tank through the inlet pipe. After a period of sedimentation, the pulverized coal gradually settles at the bottom of the tank, forming a bottom sediment layer. At this time, the pump is started, and the pump sucks out the pulverized coal settled at the bottom of the tank through the discharge pipe, and then discharges it through the connecting pipe, three-way valve, and slag discharge pipe. When the level gauge detects that there is no sediment at the bottom of the tank, the pump stops working. Then, the three-way valve is adjusted to connect the connecting pipe and the discharge pipe, and then the pump is started again. The pump sucks out the remaining liquid in the tank through the discharge pipe, and then discharges it through the connecting pipe, three-way valve, and discharge pipe, thereby effectively collecting and treating the pulverized coal entering the ammonium sulfate section, and the treatment process is time-saving and labor-saving.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] Please see Figure 1-5This utility model provides a coal powder separation device in a coal powder mixture, including a tank 1 and a pump body 4. An inlet pipe 11 is fixedly connected to the upper end of one side of the tank 1, and the end of the inlet pipe 11 away from the tank 1 is fixedly connected to a buffer tank for receiving the incoming coal powder mixture. A discharge pipe 12 is fixedly connected to the lower end of the other side of the tank 1 for discharging the separated liquid and coal powder. A tank cover 2 is fixed to the upper opening of the tank 1 with bolts for easy maintenance and inspection of the tank 1's interior. An adsorption assembly 3 for adsorbing coal powder is detachably connected to the upper end of the tank 1's interior. The end of the discharge pipe 12 away from the tank 1 is connected to the inlet of the pump body 4. A connecting pipe 5 is fixedly connected to the outlet of the pump body 4, and a three-way valve 6 is fixedly connected to the end of the connecting pipe 5 away from the pump body 4. A slag discharge pipe 7 and a liquid discharge pipe 8 are fixedly connected to the two outlets of the three-way valve 6, respectively. The slag discharge pipe 7 discharges the separated coal powder, and the liquid discharge pipe 8 discharges the liquid, ensuring the separation of coal powder and liquid. A pulverized coal collection tank is installed below the slag discharge pipe 7. A level gauge 9 is fixedly connected to the upper inner wall of the tank body 1 to monitor the liquid level changes in the tank body 1 in real time. A material level gauge 10 is fixedly connected to the lower inner wall of the tank body 1 to detect the accumulation of pulverized coal in the tank body 1.

[0026] In this invention, the pulverized coal mixture first enters the tank 1 from the buffer tank via the inlet pipe 11. After a period of sedimentation, the pulverized coal gradually settles at the bottom of the tank 1, forming a bottom sediment layer. At this time, the pump 4 is started, and the pump 4 sucks out the pulverized coal settled at the bottom of the tank 1 through the outlet pipe 12, and then discharges it through the connecting pipe 5, the three-way valve 6, and the slag discharge pipe 7. When the level gauge 10 detects that there is no sediment at the bottom of the tank 1, the pump 4 stops working. Then, the three-way valve 6 is adjusted to connect the connecting pipe 5 with the outlet pipe 8, and then the pump 4 is started again. The pump 4 sucks out the remaining liquid in the tank 1 through the outlet pipe 12, and then discharges it through the connecting pipe 5, the three-way valve 6, and the outlet pipe 8, thereby effectively collecting and processing the pulverized coal entering the ammonium sulfate section.

[0027] By incorporating adsorption component 3, coal powder can be effectively adsorbed during the sedimentation process of the coal powder mixture, reducing its suspension in the liquid. As the particle size of the coal powder gradually increases, the adsorbed coal powder will naturally fall off and settle to the bottom along with the sedimentation process, forming larger coal powder particles. This not only accelerates the sedimentation process of the coal powder but also promotes the stratification of the coal powder, making coal powder separation more efficient.

[0028] Furthermore, an inlet valve 111 is fixedly connected to the inlet pipe 11, and a discharge valve 121 is fixedly connected to the discharge pipe 12.

[0029] Specifically, the pulverized coal mixture enters tank 1 from the buffer tank. During this process, the level gauge 9 continuously monitors the liquid level in tank 1. Once the liquid level reaches a predetermined height, the inlet valve 111 is closed to prevent excessive pulverized coal mixture from continuing to enter tank 1. Secondly, during the sedimentation process, the outlet valve 121 is closed. When it is necessary to discharge pulverized coal or liquid, the outlet valve 121 is opened.

[0030] Furthermore, a support ring 13 is fixedly connected to the inner side of the upper opening of the tank 1. The adsorption assembly 3 includes a fixed plate 31 and a support rod 32. The fixed plate 31 is detachably connected to the support ring 13. The support rod 32 is fixedly connected to the center of the lower surface of the fixed plate 31. Multiple adsorption plates 34 are fixed to the outer side of the support rod 32 by two sets of fixing parts 33. The two sets of fixing parts 33 are symmetrical to each other and distributed vertically.

[0031] Specifically, when the pulverized coal mixture settles in tank 1, multiple sets of adsorption plates 34 can effectively adsorb the pulverized coal. The adsorption assembly 3 and tank 1 adopt a detachable structure, which facilitates the subsequent removal of the adsorption assembly 3 for cleaning.

[0032] Furthermore, the upper surface of the support ring 13 is provided with multiple sets of slots 131 at equal intervals in an annular shape, and the lower surface edge of the fixed plate 31 is provided with multiple sets of blocks 311 at equal intervals in an annular shape. The multiple sets of blocks 311 are respectively movably inserted into the slots 131 at corresponding positions and the two are fixed together by bolts.

[0033] Specifically, when it is necessary to remove the adsorption component 3 from the tank 1, first open the tank cover 2, then remove the bolts used to fix the locking block 311 and the slot 131, and then remove the fixing plate 31 from the support ring 13. Through the cooperation between the locking block 311 and the slot 131, the fixing plate 31 can be quickly positioned with the support ring 13 during installation.

[0034] Furthermore, the fastener 33 includes two semi-circular buckles 331 symmetrically arranged on the outside of the support rod 32. The two semi-circular buckles 331 are interlocked and fixed together by bolts. The lower end of the semi-circular buckle 331 is fixedly connected to a semi-cylinder 332. A plurality of short columns 333 are fixedly arranged circumferentially on the outer wall of the semi-cylinder 332. Each short column 333 is fixedly connected to a C-shaped clip 334 at the end away from the semi-cylinder 332. The upper and lower ends of the adsorption plate 34 on the side near the support rod 32 are respectively movably inserted into the corresponding C-shaped clips 334 and fixed together by bolts.

[0035] Specifically, the adsorption plate 34 is fixed to the outside of the support rod 32 with a detachable structure, facilitating subsequent maintenance and disassembly. When it is necessary to separate the support rod 32 and the adsorption plate 34 as a whole, the operator only needs to unscrew the bolts used to fix the semi-circular buckles 331 to easily separate the two interlocking semi-circular buckles 331, thereby completely separating all the adsorption plates 34 from the support rod 32. When it is necessary to remove a set of adsorption plates 34 individually, the bolts used to fix the adsorption plate 34 to the C-clamps 334 can be removed, so that the upper and lower ends of the adsorption plate 34 are released from the two sets of C-clamps 334 at the corresponding positions.

[0036] Furthermore, multiple sets of adsorption plates 34 are arranged in a ring around the support rod 32.

[0037] Specifically, this arrangement of the adsorption plates 34 not only effectively improves the adsorption area and efficiency, but also evenly distributes the adsorption force, ensuring the balance and efficient operation of the device during use.

[0038] Furthermore, the adsorption plate 34 adopts a high-voltage electrode plate.

[0039] Specifically, the process utilizes an electric field to efficiently adsorb coal powder from the mixture. When the high-voltage electrode plate is energized, the electric field creates a strong electro-attraction on its surface, causing coal powder particles to rapidly aggregate and adhere to the plate. As coal powder continues to be adsorbed, it gradually forms larger particles. When these particles reach a certain size, they gradually detach and settle to the bottom of tank 1 due to gravity or the weakening of the electric field, thus accelerating the sedimentation and stratification process. Furthermore, when the high-voltage electrode plate is de-energized, the disappearance of the electric field causes the coal powder adsorbed on its surface to lose its adsorption force, resulting in its detachment. This allows the coal powder to quickly settle to the bottom of tank 1, achieving rapid separation and sedimentation. The de-energization and energization of the high-voltage electrode plate makes the entire sedimentation process more controllable and allows for the rapid removal of adsorbed coal powder when needed.

[0040] Furthermore, pump body 4 adopts a slag discharge pump.

[0041] Specifically, the slag pump can not only handle coal powder sediment, but also effectively suck up the liquid in tank 1.

[0042] It should be noted that the inlet valve 111, outlet valve 121, adsorption plate 34, pump body 4, three-way valve 6, level gauge 9, and material level gauge 10 mentioned above are all electrically connected to the main controller to achieve automated control of the entire system. Furthermore, the main controller can be a computer, PLC, or other conventional known device with control functions.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
