[0002] A control cabinet, also known as an electrical control cabinet, is a cabinet used to install electrical components that participate in circuit control. Boiler control cabinets may be exposed to high temperature and high humidity environments for extended periods. High humidity not only makes the control cabinet more susceptible to corrosion but can also interfere with the operation of electrical components. Furthermore, in high-temperature environments, the control tubes require cooling, increasing the likelihood of condensation. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 and Figure 2 This utility model discloses a moisture-proof boiler control cabinet, including a cabinet body 1. Electrical components are installed inside the cabinet body 1. A dehumidification box 2 is fixedly installed on one side of the cabinet body 1. The dehumidification box 2 is fixedly installed with multiple partitions 3, which divide the dehumidification box 2 into multiple accommodating spaces from top to bottom. Some accommodating spaces are filled with silica gel desiccant 4 to form silica gel desiccant 4 layers. An unfilled accommodating space is set between adjacent silica gel desiccant 4 layers. A drying pipe 51 and a return air pipe 52 are respectively set at the bottom of the dehumidification box 2. The drying pipe 51 connects the top of the dehumidification box 2 and the top of the cabinet body 1. The return air pipe 52 connects the bottom of the dehumidification box 2 and the bottom of the cabinet body 1. A circulating fan 521 is installed on the return air pipe 52. A heating wire 6 is embedded in the side wall of the accommodating space where the silica gel desiccant 4 is placed. A dehumidification exhaust pipe 61 is fixedly installed on the dehumidification box 2. A first solenoid valve 63 is installed on the dehumidification exhaust pipe 61.

[0028] Specifically, multiple compartments are set up inside the dehumidification chamber 2, with silica gel desiccants 4 placed at intervals. Air is circulated between the cabinet 1 and the dehumidification chamber 2 by a circulating fan 521. During the circulation process, the silica gel desiccants 4 absorb moisture. Heating wires 6 are embedded in the side walls of the compartments. The heating wires 6 heat the silica gel desiccants 4, causing the moisture to evaporate and be discharged through the exhaust pipe 61.

[0029] In this way, by setting up a dehumidification box 2, the gas inside the cabinet 1 is circulated and dehumidified, reducing the air humidity inside the cabinet 1, which is convenient for use in high humidity environments such as boiler environments.

[0030] In some feasible configurations, the dehumidifier box 2 is rectangular, and the partition 3 is a rectangular perforated plate. To prevent the silica gel desiccant 4 from falling off, the pore size of the partition 3 should be smaller than the particle size of the silica gel desiccant 4. By setting multiple layers of silica gel desiccant 4, the airflow is dehumidified multiple times, improving dehumidification efficiency. The heating wire 6 can be a resistance wire, which heats the silica gel desiccant 4 to a suitable temperature, causing the droplets in the micropores to evaporate and be discharged to the outside through the exhaust pipe 61. For easy heating, two thermally conductive metal plates are fixedly installed in the middle of the accommodating space, with the heating wire 6 located between the two metal plates and the silica gel desiccant 4 located on the side of the two metal plates away from the heating wire 6. To facilitate the control of the humidity inside the cabinet 1 and the heating temperature of the heating wire 6, a humidity sensor is installed inside the cabinet 1, and the humidity sensor signal is connected to the circulating fan 521. A temperature sensor is installed inside the dehumidifier box 2.

[0031] As one specific embodiment of a moisture-proof boiler control cabinet provided in the application, the first solenoid valve 63 is a two-position four-way valve with two inlets and two outlets.

[0032] Overall, by setting up a two-position four-way valve with two inlets and two outlets, it is easy to switch between the exhaust pipe 61 and the drying pipe 51, reducing the possibility that the moisture discharged by the silica gel desiccant 4 will re-enter the drying pipe 51.

[0033] Furthermore, the dehumidification box 2 is fixedly installed with an air inlet pipe 62, and a second solenoid valve 64 is fixedly installed on the air inlet pipe 62. The second solenoid valve 64 is a two-position three-way valve with dual inputs. The return air pipe 52 is connected to the input end of the second solenoid valve 64, and the circulating fan 521 is located at the output end of the second solenoid valve 64.

[0034] It should be understood that by setting up an air inlet pipe 62 and connecting the air inlet pipe 62 to the circulating fan 521, when the silica gel desiccant 4 discharges moisture, air is introduced through the air inlet pipe 62 to accelerate the discharge of moisture.

[0035] Furthermore, the exhaust pipe 61 and the air inlet pipe 62 include multiple branch pipes, which are fixedly connected to both sides of the unfilled accommodating space. A third solenoid valve 65 is installed at the output end of the circulating fan 521. The third solenoid valve 65 is a dual-output two-position three-way valve. The return air pipe 52 and the air inlet pipe 62 are connected to the two output ends of the dehumidification box 2, respectively.

[0036] It should be understood that by setting multiple branch pipes, when the silica gel desiccant 4 discharges moisture, the airflow of the exhaust pipe 61 and the air inlet pipe 62 circulates through the unfilled accommodating space, thereby reducing the impact of the moisture drawn in by the air inlet pipe 62 on the dried silica gel desiccant 4.

[0037] In some feasible configurations, the first solenoid valve 63 is a two-way, two-position, four-way valve with two inlets and two outlets. The drying pipe 51 and the exhaust pipe 61 are each connected to one channel of the first solenoid valve 63. When the drying pipe 51 is opened, the exhaust pipe 61 is cut off, and vice versa. The circulating fan 521 includes a cylindrical outer casing with a fan inside. Both ends of the casing are connected to the third solenoid valve 65 and the second solenoid valve 64 via pipes. This allows the circulating fan 521 to function both as a dehumidifying circulating airflow within the cabinet 1 and as a replacement gas when the silica gel desiccant 4 discharges moisture.

[0038] As another specific embodiment of the moisture-proof boiler control cabinet provided in the application, the partition plate 3 with at least 4 layers of silica gel desiccant is installed at an angle, and the accommodating space of the 4 layers of silica gel desiccant is equipped with removable sealing plates 31 on both sides.

[0039] Depending on the specific application scenario, after the silica gel desiccant 4 has been used for a long time, it needs to be replaced. By setting up the inclined partition plate 3 and the detachable sealing plate 31, it is easy for the silica gel desiccant 4 to flow out and be loaded.

[0040] In some feasible methods, the sealing plate 31 is a rectangular plate, and L-shaped sliding rails are provided on both sides of the dehumidification box 2 at the upper and lower positions of the sealing plate 31, and the sealing plate 31 is inserted and installed.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
