Detailed Implementation
[0022] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.
[0023] Example 1
[0024] refer to Figure 1 This embodiment provides a water replenishment system for a slag discharger, including a slag ship 1, a water replenishment component (not shown in the figure) and a control component (not shown in the figure) installed inside the slag ship 1. The water replenishment component includes a water replenishment valve 21, a float 22 and a connecting rod 23. The water replenishment valve 21 is installed on the slag ship 1 and has an inlet 211 and an outlet 212. The inlet 211 is connected to a water source through a water replenishment pipe 31, and the outlet 212 is connected to the interior of the slag ship 1. The float 22 is movably installed inside the slag ship 1. The float 22 can be linked with the water replenishment valve 21 through the connecting rod 23. When the float 22 moves with the rise and fall of the water level, it can push the water replenishment valve 21 to close or open through the connecting rod, thereby realizing the automatic adjustment of the opening of the water replenishment valve 21 according to the water level change inside the slag ship 1, thereby controlling the water level inside the slag ship within the normal range, improving the reliability of replenishing water to the slag discharger to a reasonable water level, and effectively ensuring production safety, environmental protection and stable equipment operation.
[0025] In this embodiment, the water replenishment valve 21 includes a valve body and a valve core. The valve body has an inlet 211 and an outlet 212. The valve core is movably disposed within the valve body and is used to control the communication state between the inlet 211 and the outlet 212. The float 22 is linked to the valve core via a connecting rod 23. When the water level in the slag ship 1 drops, the float 22 moves downward with the water level, driving the valve core to open the water replenishment valve 21 via the connecting rod 23. Water flows in from the outlet of the water replenishment valve 21 to replenish the water level. Conversely, when the water level in the slag ship 1 rises to a set height, the float 22 moves upward with the water level, pushing the valve core to close the water replenishment valve 21 via the connecting rod 23, thereby cutting off the water flow and ending the water replenishment.
[0026] In this embodiment, a water replenishment tank 11 and a slag receiving tank 12 are provided at intervals inside the slag ship 1. The slag receiving tank 12 is connected to the water replenishment tank 11 through a water inlet. The water replenishment component is installed inside the water replenishment tank 11, thus isolating the water replenishment component from impurities in the slag receiving tank 12 and preventing impurities from affecting the normal operation of the water replenishment component, effectively ensuring the normal water replenishment of the water replenishment component. Furthermore, a filter or a one-way valve can be added to the water inlet. The one-way valve is configured to allow water to flow unidirectionally from the water replenishment tank 11 to the slag receiving tank 12, thus preventing impurities in the slag receiving tank 12 from entering the water replenishment tank 11.
[0027] refer to Figure 1 Furthermore, it also includes a level sensor 42 and / or a scraper assembly 5. The level sensor 42 is installed on the slag ship 1 and electrically connected to the control assembly to detect the water level inside the slag ship 1. The control assembly is used to input the water level signal data detected by the level sensor 42 into the DCS monitoring screen to enhance the monitoring of the water level of the slag discharger, thereby checking whether the water supply component is working properly and whether the water seal is maintained, and avoiding abnormal water supply to the slag discharger. Once an abnormal water supply is detected, it is convenient to make timely adjustments or repairs, thereby avoiding abnormal situations such as dust generation from dry slag due to abnormal water supply to the slag discharger.
[0028] The scraper assembly 5 is movably mounted on the slag ship 1 and electrically connected to the control assembly, used to push the quenched hot residue inside the slag ship 1 toward the slag outlet. In this embodiment, the scraper assembly 5 includes a scraper body, a hydraulic cylinder 51, and a transmission rod. The hydraulic cylinder 51 is located at one end of the slag ship 1 near the water replenishment assembly. The hydraulic cylinder 51 is driven to the scraper body via the transmission rod. The hydraulic cylinder 51 is used to drive the pressure plate body to compress the hot residue and transport the hot residue toward the edge of the slag outlet.
[0029] The specific structure of the liquid level sensor 42 includes, but is not limited to, any of the following:
[0030] The first type of liquid level sensor 42 includes a first magnetic element, a second magnetic element, and a detection component. The first magnetic element is disposed on the float 22, and the second magnetic element is disposed on the slag ship 1 and electrically connected to the detection component. This allows the float 22 to move synchronously with the rise and fall of the water level, thereby causing the first magnetic element to move, which in turn changes the relative position of the first and second magnetic elements, resulting in a change in electrical quantity (or magnetic field magnitude). By detecting the change in electrical quantity (or magnetic field magnitude), the liquid level in the slag ship is reflected, and the relevant liquid level signal data is introduced into the DCS monitoring panel to enhance monitoring.
[0031] The second type involves a liquid level sensor 42 comprising a magnetic float and a reed switch. A guide groove, connected to the interior of the slag barge 1, is provided inside the slag barge 1. The magnetic float is positioned within the guide groove, moving up and down with the water level. The reed switch is located outside the slag barge 1, close to the magnetic float. When the magnetic float moves to a height relative to the reed switch with the water flow, it cuts magnetic lines of force, opening a circuit between the magnetic float and the reed switch. This allows for precise determination of the water level inside the slag barge 1 based on the circuit's continuity.
[0032] Example 2
[0033] refer to Figure 2 The difference between this embodiment and embodiment 1 is that a water storage tank 13 is provided inside the slag ship 1. The water storage tank 13 is connected to the water supply source through a water inlet component (not shown in the figure). The control component is electrically connected to the water inlet component. The water supply component is located inside the slag ship 1 and outside the water storage tank 13. The water inlet 211 of the water supply valve 21 is connected to the water supply port of the water storage tank 13 so as to realize the water supply to the inside of the slag ship 1 through the water storage tank 13.
[0034] In this embodiment, the water inlet assembly includes a water supply pipe 31 and a water inlet valve 32. The water storage tank 13 is connected to the water supply source through the water supply pipe 31. The water inlet valve 32 is installed on the water supply pipe 31 and electrically connected to the control assembly. It is used to control the flow of water through the water supply pipe 31. By controlling the water inlet assembly to inject a set amount of water into the water storage tank 13 at one time, the water injection frequency is reduced, which helps to improve the service life of the water inlet valve 32.
[0035] Furthermore, a water level detection component 41 electrically connected to the control component is provided on the water storage tank 13. The water level detection component 41 is used to detect the water level height of the water storage tank 13. When the water level in the water storage tank 13 drops to the lower limit, the water inlet component is controlled to inject water into the water storage tank 13 so that the water level in the water storage tank 13 is restored to the upper limit, thereby ensuring that the water storage tank 13 can normally replenish water for the slag ship 1.
[0036] Example 3
[0037] refer to Figure 3The difference between this embodiment and Embodiment 1 is that a temporary water inlet (not shown in the figure) is provided at the lower end of the side wall of the water storage tank 13, and a water outlet valve 14 electrically connected to the control component is provided on the temporary water inlet. Therefore, when the water replenishment component malfunctions and cannot automatically replenish water to the slag ship 1, the control component opens the water inlet valve 14, thereby enabling temporary emergency water replenishment to the slag ship 1 through the temporary water inlet, thus preventing abnormal situations such as dry slag and dust generation caused by water shortage in the slag discharge machine.
[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
