Description

Technical Field

[0001] This utility model belongs to the field of condensate treatment technology, specifically relating to a steam condensate recycling and conveying device. Background Technology

[0002] In modern industrial production, steam, as a widely used heat energy carrier, plays a crucial role in numerous fields. After releasing heat, steam produces a large amount of condensate. This condensate not only contains high levels of heat energy but is also relatively pure, making it highly valuable for recycling. Effective recycling of steam condensate can not only save water resources and reduce water costs for businesses but also decrease energy consumption, aligning with the development strategy of energy conservation and emission reduction.

[0003] However, existing steam condensate recycling and conveying systems have several shortcomings. Some systems have inadequate tank structure design, failing to effectively control the condensate level precisely. This can easily lead to overflow due to excessively high water levels or disruption of the conveying pump's normal operation due to excessively low water levels. Furthermore, the fixed installation position of the water level control components makes it difficult to adjust flexibly according to actual production needs, limiting the system's applicability. In addition, the tank's partition structure in some systems lacks stability and is prone to damage after prolonged use, affecting condensate separation and conveying efficiency, and reducing the reliability and service life of the steam condensate recycling and conveying system. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a steam condensate recycling and conveying device, including a water tank and a conveying pump. The inside of the water tank is divided into a water storage area and an overflow area by an overflow plate. The water storage area and the overflow area are connected by an overflow port located above the overflow plate. The water tank is provided with a water inlet and a water outlet. The water inlet is connected to a water inlet pipe, and the water outlet is connected to a water outlet pipe. The water inlet pipe is connected to the water storage area through the water inlet pipe. One end of the water outlet pipe is connected to the conveying pump, and the other end is connected to the overflow area through the water outlet pipe.

[0005] As a preferred embodiment of the above technical solution, an upper liquid level switch and a lower liquid level switch are installed in the overflow area.

[0006] As a preferred embodiment of the above technical solution, an adjusting column is provided in the overflow area. The adjusting column is vertically installed and fixedly connected to the water tank.

[0007] As a preferred embodiment of the above technical solution, the adjusting column is provided with a plurality of annular limiting grooves for clamping into which the clamps are inserted, and the annular limiting grooves are evenly spaced on the adjusting column.

[0008] As a preferred embodiment of the above technical solution, the water tank is covered with a lid.

[0009] As a preferred embodiment of the above technical solution, the overflow plate is composed of several baffles spliced ​​together from bottom to top, and the inner walls on both sides of the water tank and the bottom plate are respectively provided with slots for inserting the edges of the baffles.

[0010] The beneficial effects of this utility model are as follows: The steam condensate recycling and conveying device of this utility model achieves precise water level control through the combination of overflow plate partitioning and level switch, avoiding overflow, preventing the conveying pump from running dry, and extending its service life. The adjusting column, annular limiting groove, and clamp structure allow for flexible adjustment of the level switch installation height, adapting to various working conditions and significantly enhancing the applicability of the device.

[0012] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] like Figure 1 As shown, the steam condensate recycling and conveying device includes a water tank 1 and a conveying pump 2. The water tank 1 is internally divided into a storage area 4 and an overflow area 5 by an overflow plate 3. The storage area 4 and the overflow area 5 are connected by an overflow port 6 located above the overflow plate 3. The water tank 1 is provided with an inlet 7 and a drain 8. The inlet 7 is connected to an inlet pipe, and the drain 8 is connected to a drain pipe. The inlet pipe is connected to the storage area 4 through the inlet 7, and one end of the drain pipe is connected to the conveying pump 2, while the other end is connected to the overflow area 5 through the drain 8. The water tank 1 is internally divided into the storage area 4 and the overflow area 5 by the overflow plate 3. Steam condensate enters the storage area 4 from the inlet pipe through the inlet 7. When the water level in the storage area 4 exceeds the overflow port 6 above the overflow plate 3, the water overflows into the overflow area 5. The steam condensate in the overflow area 5 is discharged and recycled by the conveying pump 2.

[0016] Furthermore, an upper liquid level sensor 9 and a lower liquid level sensor 10 are installed in the overflow area 5. The upper liquid level sensor 9 is higher than the lower liquid level sensor 10, and the lower liquid level sensor 10 is higher than the drain outlet 8. The upper liquid level sensor 9 and the lower liquid level sensor 10 are electrically connected to the transfer pump 2. When the water level in the overflow area 5 rises to the position of the upper liquid level sensor 9, the upper liquid level sensor 9 sends a signal, and the electrically connected transfer pump 2 starts, draining the water from the overflow area 5 through the drain pipe. When the water level drops to the position of the lower liquid level sensor 10, the lower liquid level sensor 10 sends a signal, and the transfer pump 2 stops working. This allows for precise control of the start and stop of the transfer pump 2, keeping the water level in the water tank 1 within a certain range, preventing water from overflowing due to excessively high water levels, and avoiding the transfer pump 2 from running dry when the water level is too low, thus protecting the transfer pump 2, extending its service life, and ensuring the stability and reliability of the device operation.

[0017] Furthermore, an adjusting column 11 is provided within the overflow zone 5. The adjusting column 11 is vertically arranged and fixedly connected to the water tank 1. The upper liquid level sensor 9 and the lower liquid level sensor 10 are respectively clamped to the adjusting column 11 by clamps 12. By loosening the clamps 12, the liquid level sensor can be moved up and down along the adjusting column 11 to adjust its position. This allows for flexible adjustment of the liquid level sensor height according to different working conditions and actual needs, thereby adapting to different water level control requirements, enhancing the applicability and flexibility of the device, and meeting the different needs for steam condensate water level control in various industrial production scenarios.

[0018] Furthermore, the adjusting column 11 is provided with a plurality of annular limiting grooves 13 for the clamps 12 to engage, and the annular limiting grooves 13 are evenly spaced on the adjusting column 11. The annular limiting grooves 13 provide accurate positioning for the installation of the liquid level sensor, ensuring that the liquid level sensor can be stably fixed in the set position after adjustment, avoiding displacement of the liquid level sensor position due to vibration or other factors, and ensuring the accuracy and stability of water level control.

[0019] Furthermore, the water tank 1 is covered with a lid 14. The lid 14 isolates the interior of the water tank 1 from the external environment, providing a sealing function to prevent external dust, impurities, etc. from entering the water tank 1 and contaminating the condensate, thus ensuring the water quality of the condensate. At the same time, it also reduces the heat loss of the condensate to a certain extent, which is conducive to improving the recycling efficiency of the condensate.

[0020] Furthermore, the overflow plate 3 is composed of several baffles 15 assembled sequentially from bottom to top, and slots 16 for inserting the edges of the baffles 15 are respectively provided on the inner walls on both sides and the bottom plate of the water tank 1. The splicing structure facilitates installation and disassembly, and makes it easy to adjust the height of the overflow port 6.

[0021] It is worth mentioning that the technical features of the delivery pump, liquid level switch and other related technologies involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0022] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
