Description

Technical Field

[0001] This utility model relates to the field of electrode testing equipment, and in particular to an electrode pressure testing device for a polycrystalline silicon reduction furnace. Background Technology

[0002] As a key basic material for the photovoltaic and electronic information industries, the development of its production technology and equipment is crucial. The polysilicon reduction furnace is the core equipment in the polysilicon production process, and the electrodes are indispensable components, playing a vital role in transmitting current and providing energy for silicon rod growth. With the continuous expansion of the polysilicon industry and increasingly stringent product quality requirements, polysilicon reduction furnaces are developing towards larger scale, higher efficiency, and greater intelligence, which places higher demands on the performance and reliability of the electrodes.

[0003] Existing electrode testing devices primarily rely on pressure testing. After the reduction furnace is assembled, a pressure test is performed on the entire system. This method treats the reduction furnace as a single unit, injecting gas or liquid at a specific pressure into the furnace and then monitoring pressure changes and observing for leaks to determine the sealing and pressure resistance of the electrodes and the entire system. The operational procedure is as follows: First, assemble all components of the reduction furnace and connect all pipes and interfaces; then, use a common medium pipeline to inject the test medium into the furnace, gradually increasing the pressure to the specified value according to a predetermined pressure curve; finally, during the pressure holding phase, operators visually inspect the furnace surface and electrode connections for signs of leakage such as bubbles or liquid seepage, while simultaneously recording pressure fluctuations using pressure monitoring instruments.

[0004] However, existing technologies have the following drawbacks:

[0005] First, pressure testing the entire reduction furnace system involves a large number of devices and components, making test preparation cumbersome. Furthermore, when problems occur during pressure testing, it is difficult to quickly determine whether the fault lies with the electrodes or other parts of the system, making it impossible to accurately assess the condition of the electrodes.

[0006] Secondly, during the overall pressure test, the presence of other components in the system may interfere with the judgment of the actual pressure resistance and sealing performance of the electrodes, which may easily lead to misjudgment and prevent some potential electrode problems from being discovered and resolved in a timely manner. Utility Model Content

[0007] In view of this, the present invention provides a polycrystalline silicon reduction furnace electrode pressure testing device, the main purpose of which is to provide a polycrystalline silicon reduction furnace electrode pressure testing device that can quickly detect and judge the electrodes.

[0008] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0009] This utility model embodiment provides an electrode pressure testing device for a polycrystalline silicon reduction furnace, the device comprising:

[0010] A water supply component, comprising a water tank and a water supply pipeline, wherein the outlet end of the water supply pipeline extends into the water tank;

[0011] The pressure testing component includes an air supply line, a detection component, and an electrode. The air supply line passes through the side wall of the water tank and includes an outer line and an inner line. The outer line is connected to the inner line, the inner line is located inside the water tank, and the outer line is located outside the water tank. The electrode is connected to the inner line, and the detection component is connected to the outer line.

[0012] Furthermore, the gas supply line also includes a quick connector, which is installed on the inner pipeline, and the electrode is connected to the quick connector.

[0013] Furthermore, the inner pipeline includes a connecting pipeline and a branch pipeline. The two ends of the connecting pipeline pass through the side wall of the water tank and are connected to the outer pipeline. One end of the branch pipeline is connected to the connecting pipeline, and the other end is connected to the electrode.

[0014] Furthermore, the pressure testing component also includes a first valve and a second valve, which are respectively installed on the external pipelines on both sides of the water tank.

[0015] Furthermore, the pressure testing component also includes an inflation component, which is connected to one end of the external pipeline.

[0016] Furthermore, the detection component includes a pressure sensor and a display, with the detection end of the pressure sensor extending into the outer pipeline and the pressure sensor connected to the display.

[0017] Furthermore, the water supply component also includes a drainage component, which is disposed at the lower part of the water tank.

[0018] Furthermore, the water supply component also includes a water supply valve, which is installed on the water supply pipeline.

[0019] This utility model provides an electrode pressure testing device for a polycrystalline silicon reduction furnace. The water supply component supplies and loads water, comprising a water tank and a water supply pipeline, with the outlet end of the pipeline extending into the water tank. The pressure testing component tests the electrodes, comprising an air supply pipeline, a detection component, and electrodes. The air supply pipeline passes through the side wall of the water tank and includes an outer pipeline and an inner pipeline. The outer pipeline is connected to the inner pipeline, which is located inside the water tank. The outer pipeline is located outside the water tank. The electrodes are connected... The detection component is connected to the external pipeline. Compared with the prior art, the first step is to assemble all components of the reduction furnace and connect all pipes and interfaces. Then, the test medium is introduced into the furnace through the common medium pipeline, and the pressure is gradually increased to the specified value according to the predetermined pressure curve. Finally, during the pressure holding stage, the operator visually observes the furnace surface, electrode connections, and other parts for signs of leakage such as bubbles or liquid seepage, and records pressure fluctuations using pressure monitoring instruments. However, the prior art has the following disadvantages: First, the entire reduction furnace system... Pressure testing involves numerous devices and components, leading to cumbersome preparation. Furthermore, when problems arise, it's difficult to quickly determine whether the fault lies with the electrode or another part of the system, hindering accurate assessment of the electrode's condition. Secondly, the presence of other components during the overall pressure test can interfere with the assessment of the electrode's actual pressure resistance and sealing performance, potentially causing misjudgments and preventing timely detection and resolution of potential electrode problems. This technical solution addresses this by installing the electrode and detection component on the air supply line, which is placed inside a water tank. When pressure testing is required, the water supply line is activated to fill the tank, followed by the air supply line, gradually increasing the pressure in both the electrode and the air supply line to the preset test pressure value. During the pressure holding process, the detection component monitors the pressure in the air supply line in real time. If bubbles appear in the water tank and the pressure in the air supply line decreases, it indicates a fault in the electrode near the bubbles. If no bubbles appear in the water tank and the pressure in the air supply line remains stable, the electrode is functioning normally. This facilitates pressure testing and detection of multiple electrodes. Attached Figure Description

[0025] This utility model provides an electrode pressure testing device for a polycrystalline silicon reduction furnace. The water supply component supplies and loads water, comprising a water tank and a water supply pipeline, with the outlet end of the pipeline extending into the water tank. The pressure testing component tests the electrodes, comprising an air supply pipeline, a detection component, and electrodes. The air supply pipeline passes through the side wall of the water tank and includes an outer pipeline and an inner pipeline. The outer pipeline is connected to the inner pipeline, which is located inside the water tank. The outer pipeline is located outside the water tank. The electrodes are connected... The detection component is connected to the external pipeline. Compared with the prior art, the first step is to assemble all components of the reduction furnace and connect all pipes and interfaces. Then, the test medium is introduced into the furnace through the common medium pipeline, and the pressure is gradually increased to the specified value according to the predetermined pressure curve. Finally, during the pressure holding stage, the operator visually observes the furnace surface, electrode connections, and other parts for signs of leakage such as bubbles or liquid seepage, and records pressure fluctuations using pressure monitoring instruments. However, the prior art has the following disadvantages: First, the entire reduction furnace system... Pressure testing involves numerous devices and components, leading to cumbersome preparation. Furthermore, when problems arise, it's difficult to quickly determine whether the fault lies with the electrode or another part of the system, hindering accurate assessment of the electrode's condition. Secondly, the presence of other components during the overall pressure test can interfere with the assessment of the electrode's actual pressure resistance and sealing performance, potentially causing misjudgments and preventing timely detection and resolution of potential electrode problems. This technical solution addresses this by installing the electrode and detection component on the air supply line, which is placed inside a water tank. When pressure testing is required, the water supply line is activated to fill the tank, followed by the air supply line, gradually increasing the pressure in both the electrode and the air supply line to the preset test pressure value. During the pressure holding process, the detection component monitors the pressure in the air supply line in real time. If bubbles appear in the water tank and the pressure in the air supply line decreases, it indicates a fault in the electrode near the bubbles. If no bubbles appear in the water tank and the pressure in the air supply line remains stable, the electrode is functioning normally. This facilitates pressure testing and detection of multiple electrodes.

[0026] The function of the aforementioned water supply component is to supply and load water. The water supply component includes a water tank and a water supply pipeline. The outlet end of the water supply pipeline extends into the water tank. The upper part of the water tank has an open structure to discharge excess gas. The water tank is made of stainless steel and welded into a cuboid or cube. The water supply pipeline can introduce high-purity demineralized water into the water tank. Optionally, the water supply component also includes a water supply valve, which is installed on the water supply pipeline to adjust the water flow rate. When the demineralized water submerges the electrode, the electrode is placed in an independent and sealed space. Optionally, the water supply component also includes a drainage component, which is located at the bottom of the water tank. The function of the drainage component is to facilitate the drainage of water from the water tank. The drainage component includes a drain pipe and a drain valve. The drain pipe is installed at the bottom of the water tank, and the drain valve is installed on the drain pipe.The pressure testing component is used to test the pressure of the electrodes. The component includes an air supply line, a detection component, and electrodes. The air supply line passes through the side wall of the water tank and includes an outer line and an inner line. The outer line is connected to the inner line, which is located inside the water tank. The outer line is located outside the water tank. The electrodes are connected to the inner line, and the detection component is connected to the outer line. Compressed air is introduced into the air supply line and enters the electrodes through the air supply line. The electrodes are located within the demineralized water. The detection component is installed on the outer line, enabling pressure testing. The system monitors the pressure within the gas supply pipeline in real time. Optionally, the monitoring component includes a pressure sensor and a display. The detection end of the pressure sensor extends into the outer pipeline, and the pressure sensor is connected to the display. The pressure sensor can monitor the pressure value within the gas supply pipeline in real time and then display the pressure value on the display. Personnel can observe the pressure data within the gas supply pipeline through the display. The inner pipeline is installed inside the water tank, and the outer pipeline is installed outside the water tank. Furthermore, the inner and outer pipelines are interconnected. Optionally, the gas supply pipeline also includes a quick connector, which is installed on the... On the inner pipeline, the electrode is connected to the quick connector. The quick connector allows for quick connection between the inner pipeline and the electrode. Specifically, the inner pipeline includes a connecting pipeline and branch pipelines. Both ends of the connecting pipeline pass through the side wall of the water tank and connect to the outer pipeline. One end of the branch pipeline is connected to the connecting pipeline, and the other end is connected to the electrode. Compressed air enters the inner pipeline and then enters the electrode through the quick connector. The remaining compressed air enters the outer pipeline, maintaining a stable pressure in the air supply pipeline. In this technical solution, the electrode is installed on the air supply pipeline, and the detection component is installed on the supply pipeline... The air supply line is placed inside a water tank. When pressure testing the electrodes, the water supply line is started to fill the tank, and then the air supply line is started, gradually increasing the pressure in the electrodes and the air supply line to the preset test pressure value. During the pressure holding process, the detection component monitors the pressure in the air supply line in real time. If air bubbles appear in the water tank and the pressure in the air supply line decreases, it indicates that the electrode near the air bubbles is faulty. If no air bubbles appear in the water tank and the pressure in the air supply line remains stable, it indicates that the electrode is normal. This achieves the technical effect of conveniently testing and inspecting multiple electrodes.

[0027] Furthermore, the pressure testing component also includes a first valve and a second valve, which are respectively installed on the external pipelines on both sides of the water tank. In this embodiment, the pressure testing component is further defined. The first and second valves are installed on the external pipelines, which include a first external pipeline and a second external pipeline. The first external pipeline passes through the water tank and connects to one end of the internal pipeline, while the second external pipeline passes through the water tank and connects to the other end of the internal pipeline. The first valve is installed on the first external pipeline, and the second valve is installed on the second external pipeline. When a pressure test is required, the second valve is closed, and the first valve is opened to introduce compressed air into the external and internal pipelines. When the pressure in the air supply pipeline and the electrode rises to a predetermined test pressure value, the first and second valves are closed, and a pressure holding process begins. During the pressure holding process, the detection component monitors the pressure in the air supply pipeline in real time. If bubbles appear in the water tank and the pressure in the air supply line decreases, it indicates that the electrode near the bubbles is faulty. If no bubbles appear in the water tank and the pressure in the air supply line remains stable, it indicates that the electrode is normal. This achieves the technical effect of facilitating pressure testing and detection of multiple electrodes. Optionally, the pressure testing component also includes an inflation component, which is connected to one end of the external pipeline. The inflation component uses an air pump or a compressed gas cylinder. Compressed gas enters the external pipeline from the inflation component and then enters the electrode. The inflation component is equipped with a pressure regulating valve, which can accurately adjust the pressure of the inflation gas according to the test requirements, thereby achieving the technical effect of adjusting the inflation pressure.
