Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling pipes, in particular to an anti-falling pipe device for circulating water outside an aluminum electrolysis medium-frequency furnace. Background Art

[0002] A medium frequency furnace is a power supply device that converts 50Hz AC power into medium frequency (300Hz to 1000Hz). It rectifies the three-phase AC power into DC power, and then converts the DC power into an adjustable medium frequency current. It supplies the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, cutting the metal material contained in the induction coil, and generating large eddy currents in the metal material.

[0003] The inlet and outlet hoses of the external circulating water of the medium frequency furnace serve as a cooling water medium and play an important role in the normal smelting process of the medium frequency furnace through the hoses. Generally, the inlet and outlet hoses of the external circulating water of the medium frequency furnace are fixed with two double steel wire clamps. Due to the need to continuously tilt the furnace, it is easy to cause the hose to continuously fall and bend, and the water pressure causes vibration on the hose fixing clamps. It is easy for the inlet and outlet hoses of the external circulating water of the medium frequency furnace to suddenly fall off during use. Once the hose falls off, it is very easy to cause an explosion accident when the medium frequency furnace is smelting molten iron. The danger and harm to on-site personnel are very huge. The existing technology also lacks a safe and stable anti-falling pipeline for the external circulating water of the aluminum electrolysis medium frequency furnace. Its durability Both usability and practicality need to be improved. At the same time, the utility model patent with announcement number CN203413963U discloses a cooling water circulation system for a medium frequency furnace, including a cooling circulating water pipe, a heat dissipation pool, a water pump and a pressure gauge. The heat dissipation pool, water pump, pressure gauge and cooling circulating water pipe are connected in a circular manner. A water distribution pipe is added between the water pump and the pressure gauge to the heat dissipation pool. The water distribution pipe is located on the heat dissipation pool and is provided with multiple water spray holes. The circulating water pipe is not safe and stable enough, and the anti-falling effect after installation is poor. Utility Model Content

[0031] This embodiment connects the entire pipeline device to the aluminum electrolysis medium frequency furnace, and can transport external circulating water through the inlet and outlet water pipes, making it easier for it to function as a cooling water medium. By setting the anti-falling components on the inlet and outlet water pipes, the inlet and outlet water pipes can be firmly fixed near the aluminum electrolysis medium frequency furnace with the cooperation of the fixed back plate and the adhesive layer, so as to prevent the water pipes from falling off, thereby ensuring the stability of the external circulating water transportation and further improving the practicality and safety of the entire pipeline device. The specific implementation is as follows:

[0032] like Figures 1 to 5As shown, a pipe device for preventing the external circulation water of an aluminum electrolysis medium frequency furnace includes an inlet and outlet water pipe 1, an anti-shedding component 2 and a monitoring box 3. The monitoring box 3 is installed in the middle of the inlet and outlet water pipe 1.

The anti-shedding component 2 includes a fixed backplate 4, a fixed frame 5 and an adhesive layer 15. The fixed frame 5 is sleeved on the outside of the inlet and outlet water pipe 1 and fixedly connected to the fixed backplate 4. The side of the fixed backplate 4 away from the fixed frame 5 is provided with an adhesive layer 15. By connecting the entire pipeline device to the aluminum electrolysis medium frequency furnace, external circulating water can be transported through the inlet and outlet water pipes 1, so that it can function as a cooling water medium. By setting the anti-falling component 2 on the inlet and outlet water pipes 1, the inlet and outlet water pipes 1 can be firmly fixed near the aluminum electrolysis medium frequency furnace with the cooperation of the fixed backboard 4 and the adhesive layer 15, so as to achieve the purpose of preventing the water pipe from falling off, thereby ensuring the stability of the external circulating water transportation and further improving the practicality and safety of the entire pipeline device.

[0033] A plurality of fixing holes 6 are formed on the fixed back plate 4, and a fixing bolt matched therewith is connected in each fixing hole 6. Through the fixing holes 6, the water pipe can be fixed by the fixing bolt, and the fixed firmness is greatly improved.

[0034] The fixed frame 5 is U-shaped. The fixed back plate 4 has an arcuate groove 16 formed on one side of the fixed frame 5 that matches the inlet and outlet pipes 1.

[0040] A display 7 is mounted on the monitoring box 3, and the display 7 is electrically connected to the pressure detector 10. By setting the display 7, pressure data can be displayed, which is convenient for staff to view and manage.

[0041] A pressure relief valve 9 is installed on the water inlet and outlet pipes 1. By the provision of the pressure relief valve 9, the water inlet and outlet pipes 1 can be decompressed to improve pipeline safety.

[0042] Working principle: The entire pipeline device is connected to the aluminum electrolysis medium frequency furnace, and external circulating water can be transported through the inlet and outlet water pipes to facilitate its role as a cooling water medium. The anti-falling components arranged on the inlet and outlet water pipes can be used to firmly fix the inlet and outlet water pipes near the aluminum electrolysis medium frequency furnace with the cooperation of the fixed back plate and the adhesive layer to prevent the water pipes from falling off, thereby ensuring the stability of the external circulating water transportation and further improving the practicality and safety of the entire pipeline device. The monitoring box arranged on the inlet and outlet water pipes can monitor the internal pressure of the pipeline through the pressure detector. When the pressure is abnormal, the alarm can be sounded through the alarm to facilitate timely inspection and processing by the staff. The reinforcing sleeve and rubber sleeve arranged on the outside of the inlet and outlet water pipes can improve the strength of the pipeline, making it not easy to bend and break, and improve the buffering protection performance of the outer surface. The anti-seepage inner pipe arranged inside the inlet and outlet water pipes can improve the anti-seepage ability and avoid leakage.
