Description

Technical Field

[0001] This utility model relates to the field of skid-mounted evaporation equipment, specifically to an intermediate electrical connection control cabinet for a skid-mounted evaporation system. Background Technology

[0002] Skid-mounted evaporation equipment divides the evaporation system into multiple independent, combinable modules, each with specific functions such as a feeding system, evaporator, condenser, and control system. Modular design facilitates easy skid-mounted integration, reducing on-site installation time and costs. Standardized interface specifications are established for each module to ensure seamless connectivity between different modules. Interfaces should include piping, valves, electrical, and instrumentation connections to simplify module docking and maintenance. The skid-mounted design considers the mechanical conditions of the equipment during transportation and on-site operation, strengthening the frame and support structure to ensure the stability of the skid-mounted equipment under various operating conditions. An advanced automated control system integrates the operating parameters of all modules into a central control system, enabling remote monitoring and intelligent operation. This not only optimizes operational efficiency but also reduces the need for on-site operators. The layout of the skid-mounted equipment is rationally arranged according to the site space and process flow, ensuring coordination between modules while considering maintenance space and personnel safety passages, improving space utilization and operational safety.

[0003] The intermediate electrical connection control cabinet of the evaporation system is a crucial component of the skid-mounted evaporation unit, primarily responsible for the evaporation of wastewater. Given the relatively low labor cost ratio in small-scale evaporation units, 95% of the work needs to be completed in the factory. This skid serves as a pilot unit (a small-scale test conducted before formal production to verify the product's feasibility and reliability, ensuring smooth testing and adjustments before mass production), requiring operation in various locations. Therefore, a rapid and error-proof structural design for the connection of highly specialized electronic components like electrical components is critical. This control cabinet is designed for easy relocation between different locations and allows for quick equipment connection even without specialized electrical personnel for installation.

[0004] For small evaporation units, the existing technology uses a method of connecting pumps, pressure, temperature, and flow sensors one by one to the control cabinet by setting labels. During transport, these labels are very easy to fall off, and damage requires on-site wiring checks, necessitating the dispatch of a professional electrical engineer for guidance. Incorrect connections can damage on-site sensors, causing project delays. Furthermore, the cables for the pumps and sensors need to be laid to the control cabinet, which requires movement between two skids and cannot be placed in the on-site cable trays, making them extremely susceptible to damage. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as damage to components due to label fall-off, easy damage to cables, and the need for on-site guidance from professional engineers. This invention provides an intermediate electrical connection control cabinet for a skid-mounted evaporator system. This invention improves upon small skid-mounted evaporators by quickly connecting male and female connectors, ensuring rapid connection of electrical components, accurate and reliable connection of pumps and instruments, improving the efficiency of skid installation on-site, and reducing on-site assembly time.

[0018] Furthermore, several openings are provided on the side wall of the control cabinet housing, and cable connectors or controller bases are connected through these openings. When cable connectors are used, the connection points are sealed as much as possible to prevent moisture from entering.

[0019] Furthermore, in addition to several control connectors, the control cabinet housing also includes intermediate relays. These intermediate relays connect to all electrical components on the heat exchanger skid; these electrical components include at least pumps, pressure sensors, temperature sensors, flow meters, and other instruments. The main control cabinet on the heat exchanger skid receives signals from the pressure, temperature, and flow sensors on the heat exchanger skid via intermediate connection cabinets, and controls the start and stop of the power components such as pumps on the heat exchanger skid. The function of the intermediate relays is to isolate the main circuit and the control circuit, and amplify the control signals.
