Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, and more specifically, to a water heat equalization mechanism for a steam boiler. Background Technology

[0002] Steam boilers can be classified according to fuel type, such as electric steam boilers, oil-fired steam boilers, and gas-fired steam boilers; according to fuel supply method, they can be classified as manually operated steam boilers and fully automatic chain grate steam boilers; according to structure, they can be classified as vertical steam boilers and horizontal steam boilers. Small steam boilers are mostly single- or double-pass vertical structures, while large steam boilers are mostly three-pass horizontal structures.

[0003] After searching, it was found that application number CN202410307381.1, entitled "A Waste Heat Power Generation System for Hazardous Waste Incineration," uses a boiler to heat water and utilize waste heat. During heating, the steam generated by the boiler drives a pneumatic vane to rotate, which, through a pulley and belt, drives an agitator to rotate, thus stirring and homogenizing the water. However, in actual use, the initial flow rate of steam inside the boiler is slow, making it difficult to drive the pneumatic vane to rotate. Furthermore, the application uses an intermediate transmission structure, resulting in a significant waste of kinetic energy during transmission, further affecting the drive of the agitator. This leads to low driving force and difficulty in stable rotation of the agitator, impacting the homogenization efficiency. Further improvements are needed.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a water heat equalization mechanism for steam boilers, which has the advantage of improved working efficiency, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned advantages of improved work efficiency, the specific technical solution adopted by this utility model is as follows:

[0009] A water homogenization mechanism for a steam boiler includes a boiler water tank and a gas chamber. The gas chamber is fixedly installed on the top surface of the boiler water tank, and a turbine is installed inside the gas chamber. A shaft is fixedly installed on the bottom surface of the turbine, extending into the boiler water tank. A stirring rod is fixedly installed on the outer surface of the shaft. A bent pipe is fixedly installed at one end of the top surface of the boiler water tank, and an air inlet hopper is connected through the bottom of the bent pipe. A reducing pipe is connected through the other end of the air inlet hopper, and an air inlet pipe is connected through the other end of the reducing pipe. The other end of the air inlet pipe is connected through the rightmost gas chamber. Multiple sets of gas chambers are arranged, and connecting pipes connect the gas chambers.

[0010] Furthermore, the air chambers are arranged at equal intervals from right to left, and the air chambers adopt a sealed structure.

[0011] Furthermore, the turbine top surface is rotatably connected to the top surface of the air chamber via a rotary connecting seat, and the turbine, shaft, and rotary connecting seat are arranged coaxially.

[0012] Furthermore, multiple sets of connecting pipes are arranged, and the diameter of the connecting pipes decreases sequentially along the steam flow direction.

[0013] Furthermore, the shaft passes through the top surface of the furnace water tank, and the shaft is rotatably connected to the top surface of the furnace water tank through a sealed bearing.

[0014] Furthermore, the diameter of one end of the reducing pipe is larger than the diameter of the other end, and the larger diameter end of the reducing pipe is connected to the other end of the bend, while the smaller diameter end of the reducing pipe is connected to the air intake pipe.

[0015] Furthermore, the diameter of the intake pipe is larger than the maximum diameter of the connecting pipe.

[0016] Furthermore, the diameter of the bottom opening of the air inlet is larger than the diameter of the bend pipe.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a water heat equalization mechanism for steam boilers, which has the following beneficial effects:

[0019] (1) This utility model adopts a variable diameter pipe and a turbine. When the steam boiler is working, the high temperature flue is installed in the boiler water tank. The water in the boiler water tank is heated by high temperature. After the water forms steam, it enters the bend pipe along the air inlet. At this time, the cross-sectional diameter of the bend pipe is large. When the steam passes through the variable diameter pipe, the diameter of the other end of the variable diameter pipe is reduced, and the steam velocity increases, thereby increasing the outlet velocity of the air inlet pipe, thereby increasing the blowing efficiency of the turbine and the rotation efficiency of the turbine. The turbine drives the shaft and stirring rod to rotate, stirring the water inside the boiler water tank and improving the uniformity of heat distribution. The turbine directly drives the stirring rod to rotate, eliminating the problem of increased friction loss caused by intermediate force transmission. The power output is direct and stable, improving the stirring efficiency and thus improving the working efficiency.

[0020] (2) This utility model adopts multiple sets of air chambers, which are connected to multiple sets of shafts and stirring rods, improving the uniformity of stirring distribution and further improving the heat equalization efficiency of water. At the same time, the diameter of the connecting pipes connecting the air chambers decreases sequentially according to the steam flow direction, ensuring the stability of the steam flow rate and preventing the steam flow rate from significantly decreasing. This stabilizes the rotation speed of the multiple sets of shafts and the mixing efficiency of the stirring rods, further improving the working efficiency. Attached Figure Description

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a water heat equalization mechanism for a steam boiler is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a water homogenization mechanism for a steam boiler according to an embodiment of the present invention includes a boiler body water tank 1 and a gas chamber 6. The gas chamber 6 is fixedly installed on the top surface of the boiler body water tank 1, and the bottom surface of the gas chamber 6 is sealed to the top surface of the boiler body water tank 1. A turbine 7, a common device, is installed inside the gas chamber 6. A shaft 11 is fixedly installed on the bottom surface of the turbine. The shaft 11 is a smooth metal round rod that extends into the interior of the boiler body water tank 1. The distance between the bottom of the shaft 11 and the bottom surface of the boiler body water tank 1 is no more than 5 cm. A stirring rod 12 is fixedly installed on the outer surface. Multiple sets of stirring rods 12 are arranged from top to bottom and are distributed at equal angles along the central axis of the shaft 11. A bent pipe 3 is fixedly installed at one end of the top surface of the furnace water tank 1. The angle of the bent pipe 3 is 90°, and the bottom opening of the bent pipe 3 is connected to an air inlet hopper 2. The air inlet hopper 2 is located inside the furnace water tank 1, and the bottom opening of the air inlet hopper 2 is above the liquid surface. The other end of the air inlet hopper 2 is connected to a reducing pipe 4. The reducing pipe 4 has a frustum-shaped structure, and the other end of the reducing pipe 4 is connected to an air inlet pipe 5. The other end of pipe 5 is connected to the rightmost air chamber 6. The inlet pipe 5 and the rightmost connecting pipe 10 are staggered to facilitate steam flow and drive the turbine 7. Multiple sets of air chambers 6 are arranged, and connecting pipes 10 connect the air chambers 6. The connecting pipes 10 are staggered to facilitate steam flow and drive the turbine 7. When the steam boiler is working, the high-temperature flue pipe is installed in the boiler body water tank 1. The water in the boiler body water tank 1 is heated by the high temperature, and the water forms steam, which then enters the bend pipe 3 along the inlet hopper 2. At this time, the bend pipe 3 has a large cross-sectional diameter, allowing steam to pass through. When passing through the reducer pipe 4, the diameter of the other end of the reducer pipe 4 decreases, and the steam velocity increases, thereby increasing the outlet velocity of the inlet pipe 5, which in turn increases the blowing efficiency of the turbine 7 and the rotation efficiency of the turbine 7. The turbine 7 drives the shaft 11 and the stirring rod 12 to rotate, stirring the water inside the furnace water tank 1 and improving the uniformity of heat distribution. The turbine 7 directly drives the stirring rod 12 to rotate, eliminating the problem of increased friction loss caused by intermediate force transmission. The power output is direct and stable, improving the stirring efficiency and thus improving the working efficiency.

[0031] In one embodiment, the gas chambers 6 are arranged at equal intervals from right to left, and the gas chambers 6 adopt a sealed structure to avoid air leakage affecting the driving efficiency. The connecting pipe 10 connected to the exhaust end of the leftmost gas chamber 6 is connected to the boiler steam output end to facilitate the discharge of steam.

[0032] In one embodiment, the top surface of the turbine 7 is rotatably connected to the top surface inside the gas chamber 6 via a rotating connecting seat 8, and the turbine 7, shaft 11 and rotating connecting seat 8 are arranged coaxially to stabilize the rotation of the turbine 7 and prevent the turbine 7 from shaking. The shaft 11 and stirring rod 12 are arranged to avoid other equipment in the furnace water tank 1 to avoid collisions with other equipment.

[0033] In one embodiment, multiple sets of connecting pipes 10 are arranged, and the diameter of the connecting pipes 10 decreases sequentially along the steam flow direction. The decrease in the diameter of the connecting pipes 10 matches the decrease in steam velocity. Multiple sets of air chambers 6 connect multiple sets of shafts 11 and stirring rods 12, which improves the uniformity of stirring distribution and further improves the heat equalization efficiency of the water. At the same time, the diameter of the connecting pipes 10 of the connecting air chambers 6 decreases sequentially according to the steam flow direction, ensuring the stability of the steam velocity. The steam velocity will not decrease significantly, thereby stabilizing the rotation speed of the multiple sets of shafts 11 and the mixing efficiency of the stirring rods 12, further improving the working efficiency.

[0034] In one embodiment, the shaft 11 passes through the top surface of the furnace water tank 1, and the shaft 11 is rotatably connected to the top surface of the furnace water tank 1 through a sealed bearing 9, which prevents steam from leaking along the gap between the shaft 11 and the top surface of the furnace water tank 1 and improves the sealing performance.

[0035] In one embodiment, the diameter of one end of the reducer 4 is larger than that of the other end, and the larger diameter end of the reducer 4 is connected to the other end of the bend 3. The smaller diameter end of the reducer 4 is connected to the intake pipe 5. The reducer 4, the intake pipe 5 and the other end of the bend 3 are arranged coaxially to improve the smoothness of airflow.

[0036] In one embodiment, the diameter of the intake pipe 5 is larger than the maximum diameter of the connecting pipe 10, which facilitates the airflow to accelerate into the rear air chamber 6 when it flows out of the rightmost air chamber 6, thus reducing the problem of airflow velocity attenuation.

[0037] In one embodiment, the bottom diameter of the air inlet hopper 2 is larger than the diameter of the bend pipe 3, which improves the steam intake efficiency and is a common gas collection mechanism.

[0038] Working principle:

[0039] When the steam boiler is working, high-temperature flue pipes are installed in the boiler body water tank 1. The water in the boiler body water tank 1 is heated by high temperature, and the water turns into steam. After steam is generated, it enters the bend pipe 3 along the air inlet hopper 2. At this time, the cross-sectional diameter of the bend pipe 3 is large. When the steam passes through the reducer pipe 4, the diameter of the other end of the reducer pipe 4 decreases, and the steam velocity increases. This increases the outlet velocity of the air inlet pipe 5, thereby increasing the blowing efficiency of the turbine 7 and the rotation efficiency of the turbine 7. The turbine 7 drives the shaft 11 and the stirring rod 12 to rotate, stirring the water inside the boiler body water tank 1 and improving the uniformity of heat distribution. The turbine 7 directly drives... The rotation of the stirring rod 12 eliminates the problem of increased friction loss caused by intermediate force transmission, resulting in direct and stable power output, which improves stirring efficiency and thus work efficiency. At the same time, multiple sets of air chambers 6 connect multiple sets of shafts 11 and stirring rods 12, improving the uniformity of stirring distribution and further improving the heat dissipation efficiency of the water. Meanwhile, the diameter of the connecting pipes 10 connecting the air chambers 6 decreases sequentially according to the steam flow direction, ensuring the stability of the steam flow rate and preventing significant attenuation of the steam flow rate. This stabilizes the rotation speed of the multiple sets of shafts 11 and the mixing efficiency of the stirring rods 12, further improving work efficiency.
