Description

Technical Field

[0001] This utility model belongs to the field of steam boilers, and in particular relates to a steam boiler with automatic water replenishment function. Background Technology

[0002] A steam boiler, also known as a steam furnace, is a device that heats water into steam by burning fuel or using electricity. It is widely used in industrial production, power generation, and heating. Depending on their structure and application, steam boilers can be classified into fire-tube boilers, water-tube boilers, and other types.

[0003] During the operation of a steam boiler, as steam is continuously consumed, the water level inside the boiler will gradually decrease. If this water level drop is not controlled in time, it may cause the boiler to overheat or even be damaged. Currently, most traditional boilers still use a manual monitoring and water replenishment mode, relying on operators to observe the water level gauge at regular intervals and make manual adjustments. This operating method not only has the problems of slow response and high labor intensity, but also may lead to major safety accidents due to personnel fatigue or negligence. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a steam furnace with automatic water replenishment function, which aims to solve the problems mentioned in the background art.

[0005] This utility model embodiment is implemented as follows: A steam boiler with automatic water replenishment function includes a steam boiler body and a water pump. The steam boiler body includes a boiler frame, a steam outlet, a sensor, and a water replenishment pipe. A first partition and a second partition are fixedly installed inside the boiler frame. The space between the first and second partitions separates the boiler frame and forms a water tank. A combustion chamber is fixedly installed inside the water tank. A smoke chamber is fixedly installed at one end of the combustion chamber. The side of the second partition opposite to the water tank forms a second smoke chamber, and the side of the first partition opposite to the water tank forms a third smoke chamber. Multiple smoke pipes are also installed inside the water tank. The system includes multiple heat exchange tubes 1 and 2. Heat exchange tube 1 connects smoke chamber 1 and smoke chamber 2, and heat exchange tube 2 connects smoke chamber 2 and smoke chamber 3. A flue gas outlet is fixedly opened on the side of the furnace body corresponding to the location of smoke chamber 3. A steam outlet is fixedly opened on the top of the furnace body and connected to a water tank. A sensor is fixedly installed on the top of the furnace body and extends into the water tank. A water supply pipe is bent in an "S" shape and installed in smoke chamber 2. One end of the water supply pipe is connected to the water tank, and the other end of the water supply pipe passes through the furnace body and extends to the outside, where it is fixedly connected to a water pump. Both the sensor and the water pump are electrically connected to an external control system.

[0006] As a further embodiment of this utility model: a burner is fixedly installed on the outside of the furnace body, and the burner extends through the furnace body and the partition plate into the combustion chamber.

[0007] As a further embodiment of this utility model: multiple parallel heat exchange plates are fixedly arranged at equal intervals on the outer side of the water supply pipe, and the heat exchange plates are metal plates.

[0008] As a further embodiment of this utility model: a filter assembly is also provided at one end of the water pump, the filter assembly including an upper cover, a base, multiple filter chambers and multiple filter membranes.

[0009] As a further embodiment of this utility model: a water outlet pipe is fixedly provided at one end of the upper cover, a water inlet pipe is fixedly provided at one end of the base, and the water outlet pipe is fixedly connected to the water pump inlet.

[0010] As a further embodiment of this utility model: multiple filter chambers and multiple filter membranes are alternately arranged and installed between the top cover and the base.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The present invention provides a steam boiler with an automatic water replenishment function. During use, a sensor detects the water level in the water tank. When the water level is low, the external control system controls the water pump to pump water into the water tank through the water replenishment pipe to replenish the water. At the same time, the heat from the high-temperature flue gas generated in the combustion chamber is fully released into the water tank through the flue to maximize heat utilization. The low-temperature water in the water replenishment pipe is preheated when passing through the water replenishment pipe to prevent the low-temperature water from being directly discharged into the water tank, which would cause drastic changes in the steam temperature.

[0013] 2. The present invention provides a steam boiler with automatic water replenishment function. By setting a heat exchange plate, the contact area between the water replenishment pipe and the high-temperature flue gas is increased, thereby improving the preheating efficiency of the low-temperature water in the water replenishment pipe and further recovering the residual heat in the flue gas.

[0014] 3. The present invention provides a steam boiler with automatic water replenishment function. Through the set filter components, the boiler water is filtered and purified, reducing the formation of scale and extending the service life of the boiler. At the same time, based on the installation structure of the filter chamber and filter membrane, multiple filter membranes can be connected in parallel to improve the filtration effect. The detachable structure also facilitates the cleaning and maintenance of the filter components in the later stage. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figures 1 to 4As shown, an embodiment of this utility model provides a steam boiler with an automatic water replenishment function, including a steam boiler body 1 and a water pump 2. The steam boiler body 1 includes a boiler body 11, a steam port 17, a sensor 18, and a water replenishment pipe 19. A first partition 111 and a second partition 112 are fixedly installed inside the boiler body 11. The partition 111 and the second partition 112 separate the boiler body 11 to form a water tank 12. A combustion chamber 13 is fixedly installed inside the water tank 12. A smoke chamber 131 is fixedly installed at one end of the combustion chamber 13.

Multiple smoke pipes 15 are also installed inside the water tank 12. The tube 15 includes multiple heat exchange tubes 151 and 152. The heat exchange tubes 151 connect smoke chamber 131 and smoke chamber 2132, and the heat exchange tubes 152 connect smoke chamber 2132 and smoke chamber 3133. The furnace body 11 has a flue gas outlet 16 fixedly opened on the side corresponding to the smoke chamber 3133. The steam outlet 17 is fixedly opened on the top of the furnace body 11 and connected to the water tank 12. The sensor 18 is fixedly installed on the top of the furnace body 11 and extends into the water tank 12. The water supply pipe 19 is bent in an "S" shape and installed in smoke chamber 2132. One end of the water supply pipe 19 is connected to the water tank 12, and the other end of the water supply pipe 19 passes through the furnace body 11 and extends to the outside and is fixedly connected to the water pump 2. The sensor 18 and the water pump 2 are both electrically connected to the external control system.

[0023] In one embodiment of this utility model, during use, the water level in the water tank 12 is detected by the sensor 18. When the water level is low, the water pump 2 is controlled to pump water into the water tank 12 through the water supply pipe 19 to replenish the water. At the same time, the heat from the high-temperature flue gas generated in the combustion chamber 13 is fully released into the water tank 12 through the flue pipe 15 to ensure maximum heat utilization. The low-temperature water in the water supply pipe 19 is preheated when passing through the water supply pipe 19 to prevent the low-temperature water from being directly discharged into the water tank 12, which would cause a drastic change in the steam temperature.

[0024] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a burner 14 is fixedly installed on the outside of the furnace body 11, and the burner 14 extends through the furnace body 11 and the partition plate 112 into the combustion chamber 13.

[0025] In one embodiment of this utility model, the burner 14 is provided to burn and release heat in the combustion chamber 13, which serves as the heat source for the steam furnace.

[0026] like Figure 2 and Figure 4As shown, in another embodiment of the present invention, a plurality of parallel heat exchange plates 191 are fixedly arranged at equal intervals on the outer side of the water supply pipe 19, and the heat exchange plates 191 are metal plates.

[0027] In one embodiment of this utility model, the heat exchange plate 191 is provided to increase the contact area between the water supply pipe 19 and the high-temperature flue gas, thereby improving the preheating efficiency of the low-temperature water in the water supply pipe 19 and further recovering the residual heat in the flue gas.

[0028] like Figure 2 and Figure 4 As shown, in another embodiment of the present invention, a filter assembly 3 is also provided at one end of the water pump 2. The filter assembly 3 includes an upper cover 31, a base 32, multiple filter chambers 33 and multiple filter membranes 34.

[0029] Specifically, a water outlet pipe 311 is fixedly installed at one end of the upper cover 31, and a water inlet pipe 321 is fixedly installed at one end of the base 32. The water outlet pipe 311 is fixedly connected to the water inlet of the water pump 2.

[0030] Specifically, multiple filter chambers 33 and multiple filter membranes 34 are staggered and installed between the upper cover 31 and the base 32.

[0031] In one embodiment of this utility model, the boiler water is filtered and purified by the filter assembly 3, reducing the formation of scale and extending the service life of the boiler. At the same time, based on the installation structure of the filter chamber 33 and the filter membrane 34, multiple filter membranes 34 can be connected in parallel to improve the filtration effect. The detachable structure also facilitates the cleaning and maintenance of the filter assembly 3 in the later stage.
