The following problems may occur during the water replenishment process: 1. Manual water replenishment is inefficient; 2. During the automatic water replenishment process controlled by the solenoid valve, water is easy to splash onto the furnace top bricks and damage them; 3. Scale and other foreign objects will form on the automatic water replenishment pipe when it is immersed in the heated water of the water seal seat for a long time, clogging the pipe opening. Utility Model Content

[0003] The purpose of this utility model application is to improve the problems of low efficiency, high maintenance frequency and easy damage to the furnace top bricks in the existing water filling method of furnace top water seal seat. This application provides an automatic water filling device for furnace top water seal seat.

[0004] The automatic water supply device for a furnace top water seal seat provided in this application adopts the following technical solution:

[0005] An automatic water filling device for a furnace top water seal seat, comprising:

[0006] A water storage tank is connected to a drain pipe with a valve, which supplies water to the water storage tank.

[0007] The connecting pipe is connected to the water storage tank and is installed horizontally. The position of the connecting pipe is higher than the height of the water seal seat water tank.

[0008] Multiple water inlet pipes are connected to the connecting pipes, and their bottom ends are inserted into the water tank of the water seal seat but not submerged in the water of the water seal seat tank;

[0009] The splash guard is installed at the bottom of the water inlet pipe, with its bottom submerged in the water tank of the water seal seat;

[0010] The sealing component, located at the splash guard, can seal the bottom of the water supply pipe when the water level in the water seal seat tank rises to a certain position.

[0011] Water in the storage tank flows into the corresponding water seal seat trough through connecting pipes and water inlet pipes, thus realizing the automatic water filling function of the water seal seat trough. When the water level in the water seal seat trough reaches the required level, the bottom of the water inlet pipe is sealed by a sealing component, and the splash guard effectively reduces water splashing during water filling, improving the protection effect on the furnace top bricks.

[0012] Optionally, the enclosure assembly includes a float a, a connector a, and a top plug a;

[0013] The connecting body a is a frame structure, with its top rotatably connected to the bottom of the water inlet pipe. The float a is fixed at the bottom of the connecting body and can float on the water surface.

[0014] The top plug a is fixed on the connecting body a. After the connecting body a rotates, the top plug a will seal the bottom end of the water supply pipe.

[0015] Optionally, the bottom of the connector a extends out from the bottom of the splash guard and then bends upward, so that the float a is located outside the splash guard;

[0016] A protective cylinder is fixed on the outer wall of the splash guard, directly opposite the position of the float a, and the float a is located inside the protective cylinder.

[0017] Optionally, the bottom of the water inlet pipe is inclined, with the inclined surface facing the top plug a.

[0018] Optionally, the enclosure assembly includes a float b, a connector b, and a top plug b;

[0019] Connector b is located below the water supply pipe, and a guide frame is fixed on the top of connector b. The guide frame is slidably connected to the bottom of the water supply pipe.

[0020] The top plug b is fixed to the top of the connecting body b, and the float b is fixed to the bottom of the connecting body. The float b can float on the water surface, and the top plug b can seal the bottom of the water supply pipe.

[0021] Optionally, a limiting ring is fixed at the top of the guide frame, and a limiting block is fixed at the bottom of the water supply pipe. The limiting block is located below the limiting ring and their positions are opposite.

[0022] Optionally, a water-retaining ring plate is provided on the guide frame, and when the top plug b closes the water supply pipe, the water-retaining ring plate is located above the bottom end of the water supply pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The water in the storage tank is automatically filled into the water tank of the corresponding water seal seat through the connecting pipe and the water filling pipe. During the process of the water level in the water tank of the water seal seat rising, the float a will rise with the water level and drive the connecting body a to rotate. The connecting body a will seal the water filling pipe through the top plug a. After the water level drops, water will continue to be added through the water filling pipe, so as to realize the automatic water filling of multiple water seal seats.

[0025] 2. During the process of the water level rising in the water tank of the water seal seat, the float b will rise with the water level and drive the connecting body b to move upward, which in turn causes the top plug b to move upward, so that the top plug b seals the bottom of the water filling pipe. After the water level drops, water will be automatically added through the water filling pipe. The setting of the baffle ring plate can effectively reduce the splashing of water during the process of sealing the water filling pipe.

[0026] 3. The splash guard not only effectively reduces liquid splashing during water addition, but also effectively shields the bottom of the water inlet pipe, reducing corrosion and preventing the water inlet pipe from contacting the water in the water seal seat tank, thus extending the service life of the water inlet pipe. On the other hand, the splash guard also keeps the water level in the waterproof cylinder stable, reducing the impact on the sealing components. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses an automatic water filling device for a furnace top water seal seat.

[0034] Example 1

[0035] refer to Figure 1The automatic water supply device for the furnace top water seal seat includes a water storage tank 1, a connecting pipe 2, a water supply pipe 3, and a splash guard 4. The water storage tank 1 is connected to a drain pipe with a valve, which supplies water to the water storage tank 1. The connecting pipe 2 is connected to the water storage tank 1 and is horizontally positioned above the water tank trough of the water seal seat. In this embodiment, two water storage tanks 1 are configured for water supply in one row of water seal seats, sharing the same connecting pipe 2, meaning that both ends of the connecting pipe 2 are connected to different water storage tanks 1. In this embodiment, the bottom of the connecting pipe 2 is supported by a frame. There are multiple water supply pipes 3, the number of which is the same as the number of water seal seats in one row. The water supply pipes 3 are connected to the connecting pipe 2, and their bottom ends are inserted into the water tank of the water seal seat. The bottom ends of the water supply pipes 3 are not submerged in the water in the water tank of the water seal seat. The splash guard 4 is mounted on the bottom end of the water supply pipes 3, with the bottom of the splash guard 4 submerged in the water in the water tank of the water seal seat, covering the bottom of the water supply pipes 3. The splash guard 4 is equipped with a sealing component 5, which can seal the bottom of the water supply pipe 3 when the water level in the water seal seat rises to a certain position.

[0036] Water in the storage tank 1 flows into the water tank of the water seal seat through the connecting pipe 2 and the water filling pipe 3, automatically adding water to the corresponding water tank. When the water in the water tank reaches the corresponding position, the sealing component 5 seals the bottom of the water filling pipe 3, stopping the water filling, thus realizing automatic water filling of multiple water seal seats. The waterproof sleeve not only prevents the bottom of the water filling pipe 3 from extending into the water tank of the water seal seat, improving its service life, but also reduces water splashing during the water filling process, improving the protection of the furnace roof bricks.

[0037] refer to Figure 2 The sealing component 5 includes a float a5a2, a connector a5a1, and a top plug a5a3. The connector a5a1 is a frame structure, with its top rotatably connected to the bottom of the water inlet pipe 3. The float a5a2 is fixed to the bottom of the connector and can float on the water surface. The float a5a2 can be made of various lightweight or hollow materials, such as foam; in this embodiment, the float a5a2 is a hollow plastic sphere. The top plug a5a3 is fixed to the connector a5a1 and is made of rubber. As the float a5a2 moves up the water surface, it allows the connector a5a1 to rotate to a position where the top plug a5a3 seals the bottom of the water inlet pipe 3. The bottom of the water inlet pipe 3 is inclined, with the inclined surface facing the top plug a5a3. The bottom of the connector a5a1 extends from the bottom of the splash guard 4 and then bends upward, so that the float a5a2 is located outside the splash guard 4. A protective cylinder 41 is fixed on the outer wall of the splash shield 4, directly opposite the position of the float a5a2, and the float a5a2 is located inside the protective cylinder 41.

[0038] As the float a5a2 moves upwards on the water surface, it causes the connecting body a5a1 to rotate, ultimately causing the top plug a5a3 to seal the bottom end of the water supply pipe 3. The inclined surface at the bottom end of the water supply pipe 3 works in conjunction with the rotation of the connecting body a5a1, improving the sealing effect of the top plug a5a3 on the water supply pipe 3. Furthermore, the inclined surface at the bottom end of the water supply pipe 3 also reduces upward splashing water droplets as the top plug a5a3 approaches, causing the splashing water droplets to fly out to the sides and horizontally, improving the interception effect of the splash shield 4. The outward extension of the connecting body a5a1 effectively increases its rotation radius, thereby improving the stability and pressure of the top plug a5a3 when sealing the water supply pipe 3. The protective cylinder 41, positioned outside the splash shield 4, covers the float a5a2, reducing the degree of water surface turbulence on the float a5a2 portion. It also allows for a smaller diameter design of the protective cylinder 41, improving its interception effect on splashing water droplets.

[0039] The implementation principle of Embodiment 1 of this application is as follows: Water is supplied to the connecting pipe 2 through the water storage tanks 1 at both ends of the connecting pipe 2. The water in the connecting pipe 2 enters the water tank of the corresponding water seal seat through the water filling pipe 3, realizing automatic water filling of the water tank of the water seal seat. During the process of the water level rising in the water tank of the water seal seat, the float a5a2 moves upward and drives the connecting body a5a1 to rotate upward until the top plug a5a3 seals the bottom end of the water filling pipe 3, stopping the water filling. In this way, automatic water filling of multiple water seal seats is realized. The splash guard 4 can effectively reduce the splashing of water droplets onto the furnace top, improving the protection effect on the furnace top bricks.

[0040] Example 2

[0041] refer to Figure 3 and Figure 4The difference between Embodiment 2 and Embodiment 1 lies in the implementation principle: the bottom end of the water inlet pipe 3 is flat. The sealing component 5 includes a float b5b2, a connector b5b1, and a top plug b5b3. The connector b5b1 is located below the water inlet pipe 3, and a guide frame 5b11 is fixedly mounted on the top of the connector b5b1. The guide frame 5b11 is vertically slidably connected to the bottom of the water inlet pipe 3. A limiting ring 5b13 is fixedly mounted on the top of the guide frame 5b11, and a limiting block is fixedly mounted at the bottom of the water inlet pipe 3. The limiting block is located below the limiting ring 5b13 and is positioned opposite to it, thus preventing the guide frame 5b11 from detaching from the bottom of the water inlet pipe 3. The top plug b5b3 is fixedly mounted on the top of the connector b5b1, and the float b5b2 is fixedly mounted on the bottom of the connector. The float b5b2 can float on the water surface and can be made of various lightweight or hollow materials, such as foam. In this embodiment, the float b5b2 is a hollow plastic sphere. The float b5b2 can move with the water surface to the position where the top plug b5b3 seals the bottom end of the water supply pipe 3. A water-retaining ring plate 5b12 is provided on the guide frame 5b11. When the top plug b5b3 seals the water supply pipe 3, the water-retaining ring plate 5b12 is located above the bottom end of the water supply pipe 3. The central part of the water-retaining ring plate 5b12 is the top, and it is set to slope downwards from the center to the surrounding area.

[0042] The difference in implementation principle between Embodiment 2 and Embodiment 1 lies in the following: The float b5b2 moves the connecting body b5b1 upwards as the water level rises. The guide frame 5b11 enhances the stability of the connecting body b5b1's sliding motion. Furthermore, the positional relationship between the anti-detachment block 31 and the limiting ring 5b13 ensures that the connecting body b5b1 hangs on the water supply pipe 3 when the water level is low, thus improving the stability of the connecting body b5b1's position. As the water level rises, the top plug b5b3 seals the bottom end of the water supply pipe 3. During this process, the baffle ring 5b12 intercepts upward-splashing water, thereby reducing the probability of water droplets splashing upwards and flying out of the anti-detachment cylinder, and improving the protection effect on the furnace top bricks of the water seal seat.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
