Description

Technical Field

[0001] This utility model relates to the technical field of water replenishment devices for slag discharge machines, specifically to a stable water replenishment device and water replenishment system for a slag discharge machine. Background Technology

[0002] After boiler slag enters and exits the slag discharge machine, water needs to be added for cooling and dust suppression, and to form a water seal to prevent cold air from being drawn back into the furnace. However, the amount of slag discharged from the boiler is unstable, and the slag contains mud, sand, and lumps. Therefore, the water supply to the slag discharge machine must be adjusted according to the actual situation to prevent overflow or water shortage. The existing slag discharge machine uses manual water adjustment for water replenishment, which often results in overflow or water shortage, causing air leakage in the water seal and allowing cold air to flow back into the furnace cavity, affecting the cooling effect. Utility Model Content

[0003] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stable water supply device and water supply system for a slag discharge machine, which can effectively solve the problems in the existing technology.

[0004] Technical solution This utility model provides a stable water supply device for a slag discharge machine, including a control device. The control device includes a frame, a water supply device disposed within the frame, and connecting rods disposed on both sides of the water supply device. The water supply device includes a pipe, a drain port opened on the side wall of the pipe, and side grooves opened on both sides of the pipe. A sphere is disposed inside the pipe. Connecting blocks, pins fixed to the connecting blocks, and connecting rods fixed to the pins are fixed on both sides of the sphere. The other end of the connecting rod is connected to the valve stem in the valve for transmission.

[0005] Furthermore, the top of the frame is provided with a circular hole, and the frame is a hollow structure. The frame is symmetrically fixed with dividing plates inside, and the sphere is disposed at the top of the two sets of dividing plates.

[0006] Furthermore, the drain outlets are distributed in an equidistant array within the pipe body, and the height of the highest drain outlet from the bottom is less than the height of the side channel.

[0007] Furthermore, the connecting block is disposed in the side groove, the bottom of the pin passes through the middle of the connecting block, and a locking nut is sleeved on the bottom of the pin. A hook is fixed to the top of the connecting block, and the hook is hung and connected to the bottom of the connecting rod.

[0008] A stable water supply system for a slag discharge machine includes a control device, which is located inside a water supply tank. The pipe in the control device is connected to a valve outlet on the water supply tank. The bottom of the water supply tank is connected to a drain outlet, and one side of the water supply tank is connected to a cooling chamber.

[0009] Furthermore, the control device is located on the central side wall inside the water replenishment tank.

[0010] Beneficial effects This invention uses a connecting rod to drive the valve stem, keeping the pipe body connected to the valve outlet. Similar to a float valve, when the water level in the replenishment tank is below a threshold, the ball moves downwards under the influence of the liquid level. The connecting rod then connects with the valve stem, allowing liquid to enter the pipe body from the valve outlet. The liquid then flows out from the drain port on the pipe body, gradually filling the replenishment tank. The liquid then enters the cooling chamber from the replenishment tank, achieving a release function. When the liquid level is high, the ball prevents itself from moving upwards within the pipe body and blocks the drain port, preventing further liquid addition and achieving a sealing function to avoid interruption of cooling water flow.

[0011] In this device, the sphere is placed inside the tube. On the one hand, it can replenish the coolant, and on the other hand, the water seal in the water tank and the cooling chamber is always closed (or can be understood as the sphere contacting the tube), which avoids the situation of cold air backflow caused by water seal leakage.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example: A stable water supply device for a slag discharge machine, as shown in the attached document. Figure 2 -Appendix Figure 5 The system includes a control device 3, which includes a frame 31, a water replenishment device 32 disposed within the frame 31, and connecting rods 33 disposed on both sides of the water replenishment device 32. The water replenishment device 32 includes a pipe body 323, a drain port 321 opened on the side wall of the pipe body 323, and side grooves 322 opened on both sides of the pipe body 323. A ball 34 is disposed inside the pipe body 323. Connecting blocks 341, pins 342 fixed to the connecting blocks 341, and connecting rods 33 fixed to the pins 342 are fixed on both sides of the ball 34. The other end of the connecting rod 33 is connected to the valve stem in the valve. The frame 31 has a round hole at its top and is a hollow structure. Symmetrical partition plates 311 are fixed inside the frame 31, and the ball 34 is positioned at the top of the two partition plates 311. The hollow structure of the frame 31 and the positioning of the ball 34 via the partition plates 311 reduce the interference of water impact on the ball 34. The sliding fit between the connecting block 341 and the side groove 322, the fixing method of the pin 342 and the locking nut 344, and the hanging connection between the hook 343 and the connecting rod 33 ensure stable transmission between the ball 34 and the valve transmission mechanism, facilitate the disassembly and maintenance of components, and reduce the risk of failure due to structural loosening. The integrated design of the frame 31 and the water supply tank (fixed to the middle side wall) reduces the impact of external vibration on the control device 3 and improves the overall stability of the system.

[0018] The drain ports 321 are evenly distributed in an array within the pipe body 323, and the height of the highest drain port 321 from the bottom is less than the height of the side channel 322. In this device, the ball 34 is set inside the pipe body 323, which can replenish the coolant on the one hand, and the water seal in the water tank and cooling chamber is always closed (or can be understood as contact between the ball 34 and the pipe body 323), avoiding the situation of cold air backflow caused by water seal leakage. This technology, by setting an evenly distributed array of drain ports 321 on the pipe body 323, combined with the linkage design of the ball 34 and the valve transmission mechanism, can accurately control the number and opening degree of the drain ports 321 by the displacement of the ball 34 in the side channel 322, realizing the step adjustment of the water replenishment flow. At the same time, the design that the height of the highest drain port 321 is lower than the height of the side channel 322 ensures the continuity of water flow during the flow adjustment process, avoids sudden flow changes caused by local blockage, and meets the stable water replenishment needs of the slag discharger under different operating conditions.

[0019] The connecting block 341 is disposed in the side groove 322. The bottom of the pin 342 passes through the middle of the connecting block 341, and a locking nut 344 is sleeved on the bottom of the pin 342. A hook 343 is fixed on the top of the connecting block 341, and the hook 343 is hung and connected to the bottom of the connecting rod 33.

[0020] The connecting rod 33 is connected to the valve stem for transmission, and the pipe body 323 is kept in communication with the valve outlet. The principle is similar to that of a float valve. When the water level in the water tank is lower than the threshold, the ball 34 will move down under the action of the liquid level. The connecting rod 33 will be connected to the valve stem for transmission, and the liquid will enter the pipe body 323 from the valve outlet. The liquid will flow out from the drain port 321 on the pipe body 323 and gradually fill the water tank. The liquid will enter the cooling chamber from the water tank to achieve the function of release. When the liquid level is high, the ball 34 will prevent it from moving up in the pipe body 323 and block the drain port 321, so that the liquid will not continue to be added, achieving the function of sealing and preventing the cooling water from being interrupted.

[0021] like Figure 1 As shown, a stable water supply system for a slag discharge machine includes a control device 3, which is located inside a water supply tank 1. The pipe 323 in the control device 3 is connected to the valve outlet on the water supply tank 1. The bottom of the water supply tank 1 is connected to the drain outlet 5, and one side of the water supply tank 1 is connected to the cooling chamber 4.

[0022] The control device 3 is located on the middle side wall inside the water supply tank 1. The control device 3 is directly installed inside the water supply tank and is connected to the valve outlet, cooling chamber 4, drain outlet 5 and other components of the water supply tank, which simplifies the pipeline layout and reduces leakage points. The structural design of the frame 31 and the partition plate 311 provides independent working space for the internal components, avoiding contamination of the core components by water impurities. At the same time, through the transmission connection between the valve stem and the connecting rod 33, the valve and the flow control component can be linked and adjusted, which is convenient to dynamically adjust the water supply strategy according to the operating status of the slag discharger and adapt to the cooling and conveying needs under different loads.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
