Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, and in particular to a high-temperature sintering equipment for porous wear-resistant films. Background Technology

[0002] High-temperature sintering equipment for porous wear-resistant films is used to manufacture porous materials and coatings with specific properties, especially those materials that require high-temperature treatment to achieve high strength and wear resistance. To ensure that the material does not oxidize or undergo other adverse reactions during sintering, an atmosphere control mechanism, such as nitrogen, argon, or hydrogen supply, can be connected to provide an inert or reducing atmosphere. For materials that need to be sintered in a vacuum atmosphere, a vacuum pump can be connected to extract air from the furnace to achieve the required vacuum level.

[0003] In common high-temperature sintering equipment, there are stagnant areas of gas inside, also known as dead zones. In these areas, the airflow may be very weak or even completely still, which means that it is impossible to collect samples from these areas and cannot accurately reflect the true atmospheric conditions inside the entire sintering chamber. Setting up a mobile sampling point is not only costly but also ineffective.

[0004] Therefore, to address the issue of not being able to obtain more representative gas samples when collecting and analyzing the internal gases in the aforementioned high-temperature sintering equipment, a porous wear-resistant membrane high-temperature sintering equipment can be designed. Through the configuration of pump body one, gas pipe one, gas pipe two, gas analysis box, delivery pump, and transport pipe, internal airflow can be achieved, ensuring that more representative gas samples can be obtained during sampling. This enhances the monitoring capability of gases generated during the sintering process and also helps to achieve uniform atmosphere distribution, reducing product quality differences caused by temperature and atmosphere inhomogeneity, thus solving the aforementioned problems.

One end of the gas pipe 10 is connected to the rear end of the pump body 8, and the other end of the gas pipe 10 is connected to the rear end surface of the sintering box 2. A fixing plate 3 is welded to the rear end of the base plate 1, and a gas analysis box 4 is installed on the upper end of the fixing plate 3.

One end of the conveying pipe 6 is fixedly connected to the outlet, and the other end of the conveying pipe 6 is fixedly connected to the cavity plate 7. The cavity plate 7 is installed on the rear end surface of the sintering box 2. The cavity plate 7 and the sintering box 2 are interconnected. After the pump body 8 is started, air is drawn from the center of the sintering box 2 through the gas pipe 9 and injected back into the sintering box 2 through the gas pipe 10. This creates a rotating gas flow pattern inside the sintering box 2, which allows the gas that was originally far away from the sampling mechanism to be sampled when sampling the gas. This allows for contact with more representative gas samples, making the gas analysis more accurate, improving the sintering quality and consistency, and enhancing the monitoring capability of the gas generated during the sintering process. At the same time, it can evenly distribute the atmosphere and reduce product quality differences caused by uneven temperature and atmosphere.

[0025] Please see Figures 1-5In this embodiment, a nitrogen storage tank 19, an argon storage tank 20, and a hydrogen storage tank 21 are installed on the upper surface of the base plate 1.

The nitrogen storage tank 19, argon storage tank 20, and hydrogen storage tank 21 are used to store different types of protective gases, nitrogen, argon, and hydrogen, respectively. These gases are crucial for atmosphere control during the sintering process, ensuring that the material does not oxidize or undergo other adverse reactions during sintering. One end of a pipe 22 is installed on the upper surface of each of the nitrogen storage tank 19, argon storage tank 20, and hydrogen storage tank 21. A gas mixing tank 24 is installed on the upper surface of the base plate 1, and the other ends of the three pipes 22 are installed on the upper surface of the gas mixing tank 24. Each storage tank 21 has a pipe 22 installed on one end of its upper surface. The pipe 22 guides the gas from each storage tank to the gas mixing tank 24. The gas mixing tank 24 receives and precisely mixes the gases from the three gas storage tanks to create an atmosphere suitable for the specific sintering process. A pump body 25 is installed on the right side surface of the gas mixing tank 24. One end of the pipe 26 is fixedly connected to the output end of the pump body 25.

A vacuum pump 12 is installed on the upper surface of the sintering box 2. The output end of the vacuum pump 12 is fixedly connected to the exhaust pipe 13.

The observation window 15 is located on the sealed box door 14. The operator can monitor the internal condition of the sintering box 2 through the observation window 15 without opening the box door, which is convenient for real-time monitoring and adjustment of process parameters.

[0027] During operation, after starting pump 8, air is drawn from the center of sintering chamber 2 through air pipe 9 and then injected back into sintering chamber 2 through air pipe 10. This creates a rotating gas flow pattern inside sintering chamber 2, allowing for the sampling of gases that were originally far from the sampling mechanism. This results in more representative gas samples, making gas analysis more accurate, improving sintering quality and consistency, enhancing the monitoring capability of gases generated during sintering, and ensuring uniform atmosphere distribution. This reduces product quality differences caused by temperature and atmosphere inhomogeneity. (Nitrogen storage tank 19...) Argon storage tank 20 and hydrogen storage tank 21 are used to store different types of protective gases, nitrogen, argon, and hydrogen, respectively. These gases are crucial for atmosphere control during the sintering process, ensuring that the material does not oxidize or undergo other adverse reactions. Pipeline 22 guides the gases from each storage tank to gas mixing tank 24. Gas mixing tank 24 is responsible for receiving and precisely mixing the gases from the three storage tanks to create atmosphere conditions suitable for specific sintering process requirements. Pump 25 is responsible for extracting the mixed gas from gas mixing tank 24 and transporting it through pipeline 26. The gas is fed into the sintering chamber 2. The solenoid valve 23 is used to precisely control the flow rate of each gas, so that the proportion of different gases entering the gas mixing chamber 24 can be adjusted as needed. The controller 11, as the central control unit of the entire device, is responsible for managing operations such as gas ratio adjustment, temperature control, and vacuum adjustment to ensure that the sintering process is carried out according to preset parameters. The temperature detection module 27 monitors the temperature change in the sintering chamber 2 in real time and feeds the data back to the controller 11 so as to accurately control the heating process and maintain the required sintering temperature. The waste gas treatment chamber 16 is mainly used to collect and treat the waste gas generated during the sintering process. The transport pump 17 is used to extract the waste gas in the sintering chamber 2 and transport it to the waste gas treatment chamber 16 for treatment. The vacuum pump 12 is used to extract the air in the sintering chamber 2 to create the required vacuum environment, which is suitable for materials that need to be sintered under oxygen-free conditions. The sealed chamber door 14 provides a safe and closed working environment to prevent external impurities from entering the sintering chamber 2 and affecting the process. The observation window 15 is located on the sealed chamber door 14. The operator can monitor the situation inside the sintering chamber 2 through the observation window 15 without opening the chamber door, which is convenient for real-time monitoring and adjustment of process parameters.

[0028] Through the above steps, after starting pump 8, air is drawn from the center of sintering chamber 2 through air pipe 9 and then injected back into sintering chamber 2 through air pipe 10. This creates a rotating gas flow pattern inside sintering chamber 2, allowing for the sampling of gases that were originally far from the sampling mechanism. This provides access to more representative gas samples, making gas analysis more accurate, improving sintering quality and consistency, and enhancing the monitoring capability of gases generated during sintering. It also ensures uniform atmosphere distribution, reducing product quality differences caused by uneven temperature and atmosphere. This solves the problem common in high-temperature sintering equipment where it is impossible to access more representative gas samples when collecting and analyzing internal gases.
