Description

Technical Field

[0001] This utility model relates to the field of waste heat boiler technology, and in particular to an automatic sewage discharge device for waste heat boilers in waste heat power generation equipment. Background Technology

[0002] Waste heat power generation is a technology that converts excess heat energy from production processes into electrical energy. It not only saves energy but also benefits the environment. A key piece of equipment in waste heat power generation is the waste heat boiler. It uses the heat or combustible material in waste gas, waste liquid, or other working fluids as a heat source to produce steam for power generation. Because the working fluid temperature is not high, the boiler is large and consumes a lot of metal; therefore, waste heat boilers require wastewater treatment during operation.

[0003] However, existing waste heat boilers typically require workers to manually test and treat the water inside the boiler before manually turning the valve to discharge the waste heat, which increases the labor intensity of workers. Furthermore, the inconvenience of automatically turning the valve to discharge the waste heat results in low efficiency during the discharge process, thus reducing the practicality of the discharge device. Therefore, this invention proposes an automatic waste heat boiler discharge device for waste heat power generation equipment to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic sewage discharge device for the waste heat boiler of a waste heat power generation equipment. This solves the problem that in the prior art, it is inconvenient to automatically turn the valve to automatically discharge sewage from the waste heat boiler, resulting in low efficiency during sewage discharge and thus reducing the practicality of the sewage discharge device in use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic sewage discharge device for a waste heat power generation equipment, including a base, a boiler body installed at the top of the base, a feed pipe installed at the bottom of the boiler body, a gate valve installed at one end of the feed pipe, an external valve installed at one end of the gate valve, a sewage discharge pipe installed at one end of the external valve, an installation frame installed at the front end of the base, a first power mechanism provided above the gate valve, a second power mechanism provided above the external valve, and a cleaning mechanism provided inside the sewage discharge pipe;

[0006] The first power mechanism includes a first electric telescopic rod, a mounting cavity, a first servo motor, a worm gear, a worm wheel, and a first rotating block. The first electric telescopic rod is mounted on the top of the mounting frame, and its bottom end extends to the bottom of the mounting frame. The output end of the first electric telescopic rod is fitted with the mounting cavity. The first servo motor is mounted on one end of the mounting cavity. A worm gear is mounted on one side inside the mounting cavity. The output end of the first servo motor is connected to one end of the worm gear. A worm wheel meshes with one side of the worm gear, and a first rotating block is mounted below the worm wheel.

[0007] A further improvement is that the first rotating block has a U-shaped design and is located on the inner side of the upper rotating wheel of the gate valve.

[0008] A further improvement is made in that: the second power mechanism includes a second electric telescopic rod, a mounting plate, a second servo motor, a rotating rod, a second rotating block, and a limiting structure. The second electric telescopic rod is mounted on the top of the mounting frame, and the bottom end of the second electric telescopic rod extends to the bottom of the mounting frame. A mounting plate is mounted on the bottom end of the second electric telescopic rod, a second servo motor is mounted on the top of the mounting plate, and a rotating rod is mounted on the bottom end of the mounting plate. The output end of the second servo motor is connected to one end of the rotating rod, and a second rotating block is mounted on the lower end of the rotating rod. The second rotating block is located outside the handle above the outer valve.

[0009] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened inside the mounting plate, and the limiting block is set inside the limiting groove. The bottom end of the limiting block is connected to the top end of the rotating rod.

[0010] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0011] A further improvement is that the cleaning mechanism includes a mounting base, a positioning groove, a positioning block, and a brush. The mounting base is installed on the top of the mounting frame. A positioning groove is provided on the inner side of the mounting base. A positioning block is provided inside the positioning groove. A brush is installed at one end of the positioning block. The brush is located inside the drain pipe.

[0012] The beneficial effects of this utility model are as follows: By setting a first power mechanism and a second power mechanism above the gate valve and the outer valve respectively, the gate valve and the outer valve can be automatically opened and closed by the cooperation between the first electric telescopic rod, mounting cavity, first servo motor, worm gear, worm wheel, and first rotating block of the first power mechanism and the second electric telescopic rod, mounting plate, second servo motor, rotating rod, second rotating block, limit groove, and limit block of the second power mechanism. This eliminates the need for manual operation of the gate valve and the outer valve, making sewage discharge more convenient and faster, thus greatly improving the practicality of the device. Furthermore, by setting a cleaning mechanism inside the sewage pipe, the cleaning mechanism's mounting base, positioning groove, positioning block, and brush cooperate to clean the inner wall of the sewage pipe, which may be affected by reduced water flow impact after passing through the two valves. This allows workers to manually rotate the brush to clean the inner wall of the sewage pipe, improving the device's effectiveness and overall usability. Attached Figure Description

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatic waste heat boiler sewage discharge device for waste heat power generation equipment, including a base 1, a boiler body 2 installed at the top of the base 1, a feed pipe 3 installed at the bottom of the boiler body 2, a gate valve 4 installed at one end of the feed pipe 3, an external valve 5 installed at one end of the gate valve 4, a sewage discharge pipe 6 installed at one end of the external valve 5, an mounting frame 7 installed at the front end of the base 1, a first power mechanism arranged above the gate valve 4, a second power mechanism arranged above the external valve 5, and a cleaning mechanism arranged inside the sewage discharge pipe 6.

[0021] The first power mechanism includes a first electric telescopic rod 8, a mounting cavity 9, a first servo motor 10, a worm gear 11, a worm wheel 12, and a first rotating block 13. The first electric telescopic rod 8 is mounted on the top of the mounting frame 7, and its bottom end extends to the bottom of the mounting frame 7. The output end of the first electric telescopic rod 8 is fitted with the mounting cavity 9. The first servo motor 10 is mounted on one end of the mounting cavity 9. The worm gear 11 is mounted on one side inside the mounting cavity 9. The output end of the first servo motor 10 is connected to one end of the worm gear 11, and a worm wheel 12 meshes with one side of the worm gear 11. 2. A first rotating block 13 is installed below the worm gear 12. The first rotating block 13 has a U-shaped design and is located inside the rotating wheel above the gate valve 4. In use, the first electric telescopic rod 8 is activated to drive the mounting cavity 9 and the first rotating block 13 to move downward, so that the first rotating block 13 is located inside the rotating wheel above the gate valve 4. At this time, the first servo motor 10 is activated to drive the worm gear 11 to rotate, thus driving the worm gear 12 to rotate. The worm gear 12 drives the first rotating block 13 to rotate, and the first rotating block 13 opens the gate valve 4, improving the convenience of the device in use.

[0022] The second power mechanism includes a second electric telescopic rod 14, a mounting plate 15, a second servo motor 16, a rotating rod 17, a second rotating block 18, and a limiting structure. The second electric telescopic rod 14 is mounted on the top of the mounting frame 7, and its bottom end extends below the mounting frame 7. The mounting plate 15 is mounted on the bottom end of the second electric telescopic rod 14. The second servo motor 16 is mounted on the top of the mounting plate 15, and the rotating rod 17 is mounted on the bottom end of the mounting plate 15. The output end of the second servo motor 16 is connected to one end of the rotating rod 17. The second rotating block 18 is mounted on the lower end of the rotating rod 17 and is located above the outer valve 5. On the outside of the hand, when in use, the second electric telescopic rod 14 is activated to drive the second rotating block 18 to move downward, so that the second rotating block 18 is located on the outside of the handle above the outer valve 5. Then, the second servo motor 16 is activated. Under the limit of the limit groove 19 and the limit block 20, the second servo motor 16 drives the rotating rod 17 to rotate, thereby opening the outer valve 5 and realizing the automatic sewage discharge of the boiler body 2. It can drive the gate valve 4 and the outer valve 5 to open and close automatically, without the need for workers to manually open and close the gate valve 4 and the outer valve 5. This makes the gate valve 4 and the outer valve 5 more convenient and faster when performing sewage discharge, thus greatly improving the practicality of the device in use.

[0023] The limiting structure includes a limiting groove 19 and a limiting block 20. The limiting groove 19 is formed inside the mounting plate 15, and the limiting block 20 is provided inside the limiting groove 19. The bottom end of the limiting block 20 is connected to the top end of the rotating rod 17. The cross-section of the limiting groove 19 is larger than the cross-section of the limiting block 20. The limiting groove 19 and the limiting block 20 form a sliding structure. In use, the mutual cooperation between the limiting groove 19 and the limiting block 20 can limit the movement of the rotating rod 17, making the rotating rod 17 more stable when moving.

[0024] The cleaning mechanism includes a mounting base 21, a positioning groove 22, a positioning block 23, and a brush 24. The mounting base 21 is installed on the top of the mounting frame 7. The positioning groove 22 is provided on the inner side of the mounting base 21. The positioning block 23 is provided inside the positioning groove 22. The brush 24 is installed at one end of the positioning block 23. The brush 24 is located inside the sewage pipe 6. During use, the impact force of the water flow may be reduced due to the sewage passing through two valves, which may cause garbage to adhere to the inner wall of the sewage pipe 6. With the cooperation of the positioning groove 22 and the positioning block 23, the brush 24 is driven to rotate, and the brush 24 is used to clean the inside of the sewage pipe 6, making the device more effective during use and greatly improving the overall effectiveness of the device.

[0025] Working principle: When it is necessary to drain the boiler body 2, the operator, with the cooperation of the positioning groove 22 and the positioning block 23, drives the brush 24 to rotate, using the brush 24 to clean the inside of the drain pipe 6. Then, the first electric telescopic rod 8 is activated to move the mounting cavity 9 and the first rotating block 13 downwards, so that the first rotating block 13 is located inside the rotating wheel above the gate valve 4. At this time, the first servo motor 10 is activated to drive the worm gear 11 to rotate, thus driving the worm wheel 12 to rotate. The worm wheel 12 drives the first rotating block 13 to rotate, using the first rotating block 13 to open the gate valve 4. Then, the second electric telescopic rod 14 is activated to move the second rotating block 18 downwards, so that the second rotating block 18 is located inside the gate valve 4. The rotating block 18 is located outside the handle above the outer valve 5. Then, the second servo motor 16 is started. Under the limit of the limit groove 19 and the limit block 20, the second servo motor 16 drives the rotating rod 17 to rotate, thereby opening the outer valve 5 and realizing the automatic sewage discharge of the boiler body 2. At this time, the second servo motor 16 is started to reverse and drive the outer valve 5 to close. The outer valve 5 is opened and closed repeatedly several times, and the water shakes up the slag, rust and other debris at the bottom of the boiler body 2 and removes them. After the sewage discharge is completed, the first servo motor 10 is started to reverse and drive the first rotating block 13 to reverse and close the gate valve 4. Then, the second servo motor 16 is started to close the outer valve 5.
