[0001] The present invention relates to the technical field of slag conveyors, and specifically, to a water replenishing and silt cleaning device for a slag conveyor. Background Art

[0002] In a waste incineration project, the water tank of the slag conveyor is prone to siltation, and the float valve often causes water replenishment failure due to the influence of floating slag, resulting in water shortage or overflow of the slag conveyor. In related technologies, it is necessary to add an external water tank, and the designed pipeline is complex, increasing the difficulty of daily operation, maintenance and overhaul. Summary of the Invention

[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] As Figure 1 and Figure 2 shown, the slag scraper water replenishment and silt cleaning device according to an embodiment of the present invention includes: a water replenishment tank 1, a flushing assembly 2 and a sewage discharge assembly 3.

[0029] The water replenishment tank 1 is connected to the slag scraper and is located inside the slag scraper. The water replenishment tank 1 is arranged opposite to the slag outlet 100 of the slag scraper. A baffle is provided inside the water replenishment tank 1, and the baffle divides the cavity of the water replenishment tank 1 into a water injection area 12 and a buffer area 13. The top of the water injection area 12 is communicated with the top of the buffer area 13, and the bottom of the buffer area 13 is communicated with the slag outlet 100 of the slag scraper. The flushing assembly 2 includes a flushing pipeline 21. The outlet end of the flushing pipeline 21 is located on one side of the buffer area 13 adjacent to the slag outlet 100 of the slag scraper, and the outlet end of the flushing pipeline is arranged adjacent to the bottom of the water replenishment tank 1. The flushing assembly 2 is used to introduce a flushing medium into the bottom of the water replenishment tank 1. The sewage discharge assembly 3 includes a sewage discharge pipe 31. The sewage discharge pipe 31 is connected to the water replenishment tank 1, and the sewage discharge port of the sewage discharge pipe 31 is located on one side of the buffer area 13 adjacent to the slag outlet 100 of the slag scraper.

[0030] Specifically, as Figure 1 and Figure 2As shown in the figure, according to the internal space layout of the slag scraper, the makeup water tank 1 is arranged in the internal idle space of the slag scraper to avoid occupying additional external space. The makeup water tank 1 is arranged on the left side of the slag discharge port 100 of the slag scraper, so that the makeup water tank 1 can directly supply makeup water to the slag scraper, and the position setting may be related to the water flow and slag flow directions in the slag scraper, facilitating the reasonable introduction of the water in the makeup water tank 1 into the working area of the slag scraper. A baffle is provided inside the makeup water tank 1. The baffle can be composed of multiple components. The baffle divides the cavity of the makeup water tank 1 into a water injection area 12 and a buffer area 13. The water injection area 12 is located on the left side of the buffer area 13. The top of the water injection area 12 is communicated with the top of the buffer area 13, and the bottom of the buffer area 13 is communicated with the slag discharge port 100 of the slag scraper, so that the water injected into the makeup water tank 1 can flow along a specific flow path in the makeup water tank 1, that is, the water flows into the buffer area 13 from the top of the water injection area 12 and then flows from the bottom of the buffer area 13 to the slag discharge port of the slag scraper.

[0031] The outlet end of the flushing pipeline 21 is arranged adjacent to the bottom of the makeup water tank 1. This means that the flushing assembly 2 can directly transport the flushing medium (such as water or compressed air, etc.) to the position near the bottom of the makeup water tank 1 close to the slag discharge port of the slag scraper for flushing this area. The sewage discharge pipe 31 is connected to the bottom of the makeup water tank 1, so that after the flushing pipeline 21 is used to flush the makeup water tank 1 to generate slag-containing sewage, the sewage can be discharged from the makeup water tank 1 through the sewage discharge pipe 31.

[0032] Thus, the flushing assembly 2 of the slag scraper makeup water and silt cleaning device in the embodiment of the present invention introduces the flushing medium into the bottom of the makeup water tank 1, which can directly scour the accumulated slag, loosen the slag and make it flow with the water flow, preventing the slag from excessively accumulating near the bottom of the makeup water tank 1 and the slag discharge port of the slag scraper, and ensuring the normal slag discharge and makeup water functions of the slag scraper. When the flushing assembly 2 flushes the slag to form slag-containing sewage, the sewage discharge pipe 31 can timely discharge this sewage from the makeup water tank 1, avoiding the sewage staying in the makeup water tank 1 and causing re-accumulation, further ensuring the cleanliness and normal operation of the makeup water tank 1 and maintaining the stability of the makeup water system of the slag scraper.

[0033] In some embodiments, in the direction from the makeup water tank 1 pointing to the slag discharge port 100 of the slag scraper, the bottom plate 11 of the makeup water tank 1 is inclined, and the bottom plate 11 of the makeup water tank 1 on the side far from the slag discharge port 100 of the slag scraper is higher than the bottom plate 11 of the makeup water tank 1 on the side adjacent to the slag discharge port 100 of the slag scraper.

[0034] Specifically, as Figure 1 and Figure 2As shown, the bottom plate 11 of the makeup water tank 1 is arranged obliquely in the left-to-right direction, and the left end of the bottom plate 11 of the makeup water tank 1 is higher than the right end of the bottom plate 11 of the makeup water tank 1, so that water can more easily flow into the buffer area 13 from the top of the water injection area 12 and then flow from the bottom of the buffer area 13 to the slag discharge port of the slag scraper. That is to say, the bottom plate 11 of the makeup water tank 1 is arranged obliquely, so that the water and slag in the makeup water tank 1 can flow along the inclined bottom plate 11 towards the slag discharge port of the slag scraper under the action of gravity. This facilitates the subsequent flushing and discharging of the slag.

[0035] It can be understood that the inclined bottom plate 11 utilizes the action of gravity to make the slag accumulated in the makeup water tank 1 move more easily towards the slag discharge port 100 of the slag scraper. In the absence of the inclined bottom plate 11, the slag may accumulate at various positions at the bottom of the makeup water tank 1 and is difficult to be discharged naturally. The inclined design allows the slag to slide towards the lower slag discharge port side under the action of the component force of its own gravity, reducing the residence time and accumulation amount of the slag in the makeup water tank 1 and reducing the risk of makeup water failure caused by slag accumulation.

[0036] When the flushing assembly 2 passes the flushing medium into the bottom of the makeup water tank 1, the inclined bottom plate 11 helps the flushing medium to better carry the slag and flow towards the discharge port of the sewage pipe 31. When the flushing medium flows on the inclined bottom plate 11, a smoother water flow can be formed, effectively flushing the slag to the vicinity of the discharge port, facilitating the sewage discharge assembly 3 to timely discharge the sewage containing slag from the makeup water tank 1 and improving the efficiency and effect of dredging.

[0037] In some embodiments, the baffle includes a first baffle 14 and a second baffle 15. The first baffle 14 and the second baffle 15 are arranged at intervals in the length direction of the makeup water tank 1. The first baffle 14 and the makeup water tank 1 define the water injection area 12, and the first baffle 14, the makeup water tank 1 and the second baffle 15 define the buffer area 13. A filter screen 16 is provided at the bottom of the second baffle 15, and the outlet of the flushing pipeline 21 is arranged adjacent to the filter screen 16.

[0038] Specifically, as Figure 1 and Figure 2 shown, the first baffle 14 is located on the left side of the second baffle 15, and there is a gap between the upper end of the first baffle 14 and the top of the makeup water tank 1, so that the water injection area 12 located on the left side of the first baffle 14 is communicated with the buffer area 13 located on the right side of the first baffle 14. The filter screen 16 provided at the bottom of the second baffle 15 can communicate the buffer area 13 with the slag discharge port 100 of the slag scraper, so that the slag discharged by the slag scraper can be deposited on the right side of the second baffle 15, facilitating the subsequent slag discharge work.

[0039] It can be understood that the filter screen 16 at the bottom of the second baffle 15 can effectively block larger particulate slag, preventing it from entering the water injection area 12 from the buffer area 13, ensuring the cleanliness of the water quality in the water injection area 12. This helps to maintain the normal operation of the entire water replenishment and sediment removal system, reducing the damage and blockage of the water replenishment equipment (such as the float valve, etc.) by the slag. While blocking the slag, the filter screen 16 allows water to pass through smoothly, ensuring the smooth flow channel of the water from the buffer area 13 to the slag discharge port of the slag scraper. It can disperse and rectify the water flow to a certain extent, making the water flow more evenly towards the slag discharge port of the slag scraper, improving the water replenishment effect.

[0040] That is to say, the outlet of the flushing pipeline 21 is arranged adjacent to the filter screen 16. When the flushing medium is ejected, it can directly scour the slag accumulated near the filter screen 16 with great force. On the one hand, it can prevent the filter screen 16 from being blocked by the slag, ensuring the filtering effect of the filter screen 16; on the other hand, it can wash up the slag near the filter screen 16, making it easier to be discharged through the sewage pipe 31 along with the water flow, enhancing the sediment removal effect.

[0041] In addition, it should be noted that the slag scraper water replenishment and sediment removal device of the embodiment of the present invention can also set multiple filter screens at different heights according to the actual use environment to adapt to different working conditions and increase the overall filtering effect of the sediment removal device.

[0042] In some embodiments, in the direction from the water replenishment tank 1 to the slag discharge port 100 of the slag scraper, the filter screen 16 protrudes towards the slag discharge port 100 of the slag scraper.

[0043] Specifically, as Figure 1 and Figure 2 shown, the filter screen 16 adopts a non-planar structure, but has a certain arc or convex shape, and its convex direction is consistent with the direction of the water flow and slag flow in the water replenishment tank 1 towards the slag discharge port of the slag scraper. Thus, the contact area between the filter screen 16 and the slag on the right side of the second baffle 15 increases, which can reduce the complete blockage of the filter screen 16 and ensure the normal water replenishment function of the water replenishment tank 1.

[0044] In other words, the convex filter screen 16 has a larger surface area compared to the planar filter screen 16. The larger filtering area allows more water and slag to pass through the filter screen 16 for filtration, improving the filtration efficiency. In the same time, it can handle more water flow, increasing the water flow rate from the buffer area 13 to the slag discharge port of the slag scraper, ensuring the timeliness of water replenishment, and at the same time, it can more effectively intercept the slag, preventing large particulate slag from entering the slag discharge port of the slag scraper, reducing the risk of wear and blockage of the slag scraper and subsequent equipment.

[0045] In addition, when the slag body rushes towards the filter screen 16 along with the water flow, the convex shape makes it difficult for the slag body to accumulate on the filter screen 16. Because the convex part will change the movement trajectory of the slag body, making it easier for the slag body to slide down along the convex curved surface to both sides of the bottom of the filter screen 16, and then under the action of the flushing assembly 2, it is more smoothly flushed towards the sewage discharge pipe 31 and discharged. Compared with the flat filter screen 16, the convex filter screen 16 reduces the residence time and accumulation amount of the slag body on the filter screen 16, reduces the probability of blockage of the filter screen 16, and ensures the long-term effective operation of the filter screen 16.

[0046] Optionally, the filter screen 16 is generally hemispherical to further reduce the probability of blockage of the filter screen 16 and ensure the long-term effective operation of the filter screen 16.

[0047] Preferably, there are multiple flushing pipelines 21, and the multiple flushing pipelines 21 are relatively arranged on both sides of the second baffle 15 along the length direction of the water replenishing tank 1. Specifically, as Figure 1 and Figure 2 shown, the multiple flushing pipelines 21 are respectively arranged on the left and right sides of the second baffle 15, so that when the flushing assembly 2 is working, it can flush the spaces on both sides of the second baffle 15. During the flushing process, the flushing medium can impact the filter screen 16 and the surrounding areas in all directions, avoiding the possible flushing dead angles of a single flushing pipeline 21. It can more effectively wash up the slag body attached to the filter screen 16 and the slag body deposited at the bottom of the water replenishing tank 1, improving the thoroughness of dredging. Among them, as Figure 2 shown, the arrows in the water replenishing tank 1 indicate the flow or disturbance streamline of the water flow.

[0048] That is to say, when the multiple flushing pipelines 21 work simultaneously, it greatly increases the flow rate and coverage range of the flushing medium, and can complete the dredging work of the bottom of the water replenishing tank 1 and the filter screen 16 in a shorter time. Compared with a single flushing pipeline 21, the design of multiple flushing pipelines 21 can significantly shorten the time required for dredging and improve the working efficiency of the entire slag dredging and water replenishing device of the slag collector.

[0049] In some embodiments, the slag dredging and water replenishing device of the embodiment of the present invention further includes a water replenishing component 4, and the water replenishing component 4 includes a water replenishing pipe 41, and the outlet end of the water replenishing pipe 41 is placed in the water injection area 12 and is arranged adjacent to the bottom plate 11 of the water replenishing tank 1.

[0050] Specifically, as Figure 1 and Figure 2As shown, the inlet end of the makeup water pipe 41 can be connected to a water pump. When water flows out of the makeup water pipe 41, it will first spread at the bottom of the water injection area 12. This can make the newly supplemented water mix more evenly with the original water in the water injection area 12, avoiding the problem that the water forms local water flow on the surface due to too high makeup water position, while the water at the bottom is not updated in time. Uniform makeup water helps to maintain the consistency of parameters such as water temperature and water quality in the water injection area 12, providing a good basis for stably supplying water to the buffer area 13 and the slag scraper later.

[0051] In addition, making up water near the bottom plate 11 of the makeup water tank 1 can promote the formation of a more reasonable water flow circulation in the water injection area 12. After the newly supplemented water accumulates at the bottom, it will gradually flow upward and exchange with the upper layer of water. This circulating flow can effectively prevent the occurrence of dead water areas in the water injection area 12, reduce the accumulation of impurities and sediments locally, and ensure the cleanliness of the water quality in the water injection area 12.

[0052] In some embodiments, the makeup water assembly 4 further includes an overflow pipe 42. The first end of the overflow pipe 42 is connected to the makeup water tank 1, and the port of the first end of the overflow pipe 42 is located above the water injection area 12.

[0053] Specifically, as Figure 1 and Figure 2 shown, arranging the overflow pipe 42 above the water injection area 12 enables it to monitor the water level in the water injection area 12, and the other end of the overflow pipe 42 can be connected to a suitable drainage place (such as a drainage pipe or a collection container, etc.) to drain the overflowed water out of the system.

[0054] That is to say, when the makeup water pipe 41 continuously supplies water to the water injection area 12, the water level in the water injection area 12 will gradually rise. Once the water level exceeds the height of the port of the first end of the overflow pipe 42, the excess water will flow out through the overflow pipe 42. This can ensure that the water level in the water injection area 12 always remains within a safe range, avoiding water overflowing from other parts of the makeup water tank 1 due to too high water level, and thus preventing the impact on the equipment and environment around the slag scraper, ensuring the normal operating environment of the equipment.

[0055] In some embodiments, the makeup water assembly 4 further includes a control member 43. The control member 43 is connected to the makeup water pipe 41. The control member 43 includes a control part 431. The control part 431 is placed in the buffer area 13 and contacts the liquid level in the buffer area 13. The control part 431 is used to monitor the liquid level height in the buffer area 13 so that the control member 43 can control the on-off of the makeup water pipe 41 according to the monitoring information of the control part 431.

[0056] It can be understood that the control member 43 in the water replenishing assembly 4 is connected to the water replenishing pipe 41, enabling the control member 43 to control the on-off of the water replenishing pipe 41, thereby regulating the amount of water replenished to the water injection area 12 of the water replenishing tank 1. The control member 43 includes a control portion 431, which is placed in the buffer area 13. The control portion 431 obtains the liquid level height information in real time in this area and feeds this information back to the control member 43, and then controls the working state of the water replenishing pipe 41.

[0057] That is to say, the control portion 431 can monitor the liquid level height in the buffer area 13 in real time. When the liquid level in the buffer area 13 drops to a certain extent, the control portion 431 transmits this information to the control member 43. The control member 43 opens the water replenishing pipe 41 according to this information, allowing water to flow into the water injection area 12, and then supplementing it into the buffer area 13 through the connection relationship between the water injection area 12 and the buffer area 13 to maintain an appropriate liquid level. Conversely, when the liquid level in the buffer area 13 reaches the set upper limit, the control portion 431 also feeds back the information to the control member 43, and the control member 43 closes the water replenishing pipe 41 to stop water replenishment. This way of replenishing water on demand can accurately meet the water demand of the slag scraper, avoiding the occurrence of over-water replenishment or insufficient water replenishment.

[0058] Thus, through real-time monitoring and dynamic control, the control member 43 of the water replenishing assembly 4 can keep the water level in the buffer area 13 within a relatively stable range. The stable water level helps to ensure the normal operation of the slag scraper water replenishing and silt cleaning device, provides a continuous and stable water source for the slag scraper, thereby ensuring that the slag discharging and water replenishing processes of the slag scraper are not affected by water level fluctuations, and improving the working efficiency and stability of the equipment.

[0059] Optionally, the control member 43 is a float valve. That is to say, when the control member 43 is a float valve, the float valve is connected to the water replenishing pipe 41, and it can control the on-off of the water replenishing pipe 41 to regulate the water flow. The control portion 431 of the float valve, that is, the float part, is placed in the buffer area 13 and contacts the liquid level in the buffer area 13. The water replenishing pipe 41 introduces water into the water injection area 12, and the float valve indirectly affects the water inflow of the water injection area 12 by controlling the opening and closing of the water replenishing pipe 41 according to the change of the liquid level height in the buffer area 13, and then affects the water replenishing situation of the entire water replenishing and silt cleaning device.

[0060] It should be noted that as Figure 1 and Figure 2As shown in the figure, the distance between the maximum height of the water surface in the water injection area 12 and the connection port of the overflow pipe 42 is H1, and the distance between the maximum height of the water surface in the water injection area 12 and the maximum height of the water surface in the buffer area 13 is H2. Since the buffer is internally connected to the slag scraper, the distance H3 between the working liquid level (the maximum height of the water surface in the buffer area 13) of the slag scraper and the water replenishing liquid level of the slag scraper. Then, when the liquid level in the slag scraper is below the water replenishing liquid level of the slag scraper, the water replenishing pipe 41 is opened to replenish water to the water injection area 12 until the liquid level in the slag scraper rises from the water replenishing liquid level to the working liquid level (that is, the liquid levels of the water injection area 12 and the buffer area 13 are at a height of H2), and then the water replenishing pipe 41 is closed.

[0061] Among them, when the water level in the slag scraper drops to the water replenishing liquid level of the slag scraper, the water replenishing component 4 is opened, and at the same time, the flushing component 2 is opened to disturb the sediment at the bottom of the water replenishing tank 1 and discharge sewage by using the sewage discharging component 3. When the water level in the slag scraper rises to the working liquid level of the slag scraper, the flushing component 2 is closed to avoid the liquid level fluctuation in the buffer area 13 and reduce the detection of the liquid level height of the buffer area 13 by the control part 43, so as to more accurately control the start and stop of the water replenishing component 4. In addition, when the water replenishing component 4 is opened, the overflow pipe 42 remains open to prevent abnormalities inside the water replenishing tank 1 from causing the water surface liquid level to be too high and affecting the internal equipment of the slag scraper.

[0062] In some embodiments, for the slag scraper water replenishing and silt cleaning device of the embodiment of the present invention, the sewage discharging component 3 further includes a sewage pump, and the sewage pump is arranged on the sewage pipe 31.

[0063] It can be understood that during the actual water replenishing and silt cleaning process of the slag scraper, the sewage pipe 31 may have a certain length and bend, and the sewage will be affected by the frictional force of the pipe inner wall and the local resistance at the elbow during the flow process. The setting of the sewage pump can provide additional power for the sewage to overcome these resistances and enable the slag-containing sewage to flow more smoothly from the water replenishing tank 1 through the sewage pipe 31. Especially when there is a certain height difference or a long distance between the water replenishing tank 1 and the sewage discharge destination, the role of the sewage pump is more obvious, ensuring that the sewage can be discharged in a timely and effective manner.

[0064] In addition, the concentration of slag in the sewage formed after the slag in the slag scraper is washed may be relatively high, and the fluidity of this high-concentration sewage is relatively poor. The powerful power of the sewage pump can push the high-concentration sewage to flow in the sewage pipe 31, avoiding the influence of slag precipitation and pipeline blockage in the sewage on the sewage discharge effect. It can smoothly transport the sewage containing larger particle slag and higher-concentration impurities, ensuring the normal operation of the sewage discharge system.
