The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electric energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production. A boiler that generates steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises. Boilers for different purposes have slightly different requirements for water quality. The water quality requirements of boilers are determined by water use requirements. At the same time, the internal water quality of boilers also affects the operation safety of boilers.

Detailed implementation manners

[0022] The preferred implementation manners of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0023] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] There are differences in the water body at different depths inside the boiler, especially for particulate matter, which generally deposits at the bottom of the boiler. Therefore, if the sampling is improper, it will affect the result of water quality detection.

[0026] In view of this, the present utility model provides a boiler water quality detection device. Through the cooperation among the guide pipe, the return pipe, the telescopic rod and the leather cup, the water body inside the boiler can be driven to flow before detection, which is conducive to the balance of the water quality of the water body inside the boiler, making the water in the guide pipe have sufficient representativeness. The sensor can detect a result closer to the water body inside the boiler body, making the result more accurate and avoiding the problem of affecting the detection result due to improper sampling.

[0027] To solve the above problems in the prior art, this embodiment provides a boiler water quality detection device, including a boiler body 1. A guiding pipe 2 is connected to the bottom on one side of the boiler body 1. The upper part on one side of the guiding pipe 2 is connected to the upper part of the side of the boiler body 1 through a reflux pipe 3. A circulating detection assembly is arranged inside the guiding pipe 2. The circulating assembly includes a head 4, a telescopic rod 5, a leather cup 6 and a sensor 7. The bottom of the head 4 is threadedly connected to the inner wall of the guiding pipe 2. The bottom of the head 4 is fixedly connected to the telescopic rod 5. The bottom of the telescopic rod 5 is equipped with the leather cup 6. The sensor 7 is arranged above the leather cup 6.

[0028] In the specific implementation process, the shape of the boiler body 1 can be any shape, such as cylindrical, square, etc., as long as it meets the technical solutions recorded in this embodiment. The guiding pipe 2 and the reflux pipe 3 form a pipeline structure, which are respectively connected to the lower part and the upper part of the boiler body 1. The head 4 seals the top of the guiding pipe 2 to prevent the water inside the boiler body 1 from overflowing due to the increased pressure at high temperature. The telescopic rod 5 can drive the leather cup 6 to move up and down inside the guiding pipe 2. It can be understood that when the leather cup 6 moves downward along the guiding pipe 2, due to the concave design of the leather cup 6, the leather cup 6 will deform, so that the water flow and air move to the upper part of the leather cup 6. When the leather cup 6 moves upward along the inner wall of the guiding pipe 2, it will not deform, and then the water flow is introduced from the boiler body 1 into the guiding pipe 2 and flows back into the boiler body 1 through the reflux pipe 3. After multiple cycles, the water quality inside the boiler body 1 is balanced, ensuring that the water quality inside the guiding pipe 2 is basically the same as that inside the boiler body 1. The water inside the guiding pipe 2 is used as a detection sample, which is more reliable, and is detected by the sensor 7, such as detecting ions, particulate matters, etc. in the water. The specific model of the sensor 7 is not limited, as long as it meets the use requirements.

[0029] In an implementable manner, please refer to Figure 2 and Figure 3 , an installation unit is arranged at the bottom of the telescopic rod 5. The installation unit includes a connecting rod 8 and a fixing plate 9. The top of the connecting rod 8 is fixedly connected to the bottom of the telescopic rod 5. The bottom of the connecting rod 8 is fixedly connected to the leather cup 6. The outer wall of the connecting rod 8 is fixedly connected to the fixing plate 9. The top of the fixing plate 9 is fixedly connected to the sensor 7.

[0030] In the specific implementation process, the specific model of the telescopic rod 5 is not limited. For example, the telescopic rod 5 can be composed of two metal rods with different inner diameters. The metal rod with a larger diameter is the mother rod, and the metal rod with a smaller diameter is the son rod. A clamping block is arranged at one end of the son rod that penetrates into the mother rod. A sliding track is arranged inside the mother rod. The son rod moves along the track of the sliding track of the mother rod through the clamping block. Through the connecting rod 8 and the fixing plate 9, the leather cup 6 and the sensor 7 are fixed. Of course, the size of the fixing plate 9 is smaller than the outer diameter of the leather cup 6, which will not affect the guiding effect of the leather cup 6 when it reciprocates.

[0031] In addition, a protective net 10 fixed to the fixed disk 9 is provided on the outer wall of the sensor 7. In the specific implementation process, the purpose of setting the protective net 10 is to protect the sensor 7 and prevent large particles inside the boiler body 1 from damaging the sensor 7.

[0032] In an implementable manner, please refer to Figure 1 、 Figure 2 and Figure 3 , a reserved hole 11 is provided on the surface of the head 4. A wire 12 extending into the head 4 is arranged inside the reserved hole 11. The wire 12 is electrically connected to the telescopic rod 5, and a sealant 13 is filled between the wire 12 and the reserved hole 11.

[0033] In the specific implementation process, it is particularly worth noting that the reserved hole 11 is provided to facilitate the connection of the telescopic rod 5 to an external power supply. Of course, through the filling of the sealant 13, the sealing effect of the reserved hole 11 is ensured.

[0034] Furthermore, a handle 14 is fixedly connected to the outer wall of the head 4. In the specific implementation process, it is particularly worth noting that the handle 14 can be a grip rod extending outward. Both hands can hold the grip rod. The design of the handle 14 facilitates the user to rotate the head 4, which is beneficial for maintenance and repair.

[0035] In an implementable manner, please refer to Figure 1 and Figure 4 , a support 15 is sleeved on the outer wall of the guiding pipe 2. The support 15 is fixedly connected to the outer wall of the boiler body 1 by bolts. In the specific implementation process, it is particularly worth noting that multiple supports 15 are provided. For example, the supports 15 can be three and are arranged at intervals in the vertical direction. The guiding pipe 2 can be fixed by the supports 15.

[0036] In an implementable manner, the bottom of the guiding pipe 2 is connected to the boiler body 1 through a valve 16. In the specific implementation process, it is particularly worth noting that the design purpose of the valve 16 is that when not in detection, the valve 16 can be closed, and through the retraction of the telescopic rod 5, the water above the leather cup 6 can be returned to the inside of the boiler body 1.

[0037] In an implementable manner, a drain valve 17 is provided at the bottom of the guiding pipe 2. In the specific implementation process, it is particularly worth noting that the drain valve 17 can drain the residual water inside the guiding pipe 2 after the valve 16 is closed, avoiding the formation of scale and the like due to long-term water accumulation inside the guiding pipe 2.

[0038] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, those skilled in the art can easily understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
