[0002] During the oxygen-pressure ammonia leaching reaction of molybdenum concentrate, it is necessary to sample and test the pH value in the reactor. In order to facilitate sampling, a pipe joint can be used for connection. At present, when sampling, the pipe joint is generally installed on the pipeline, the pipeline valve in the reactor is driven, and the reaction liquid is led out from the joint along the pipeline to the collection container.

The skin of the staff may be contaminated with the sample. When the concentration of ammonia water is high, it is easy to cause skin irritation and burns, which endangers the health of the staff.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] During the oxygen-pressure ammonia leaching reaction of molybdenum concentrate, it is necessary to sample and test the pH value in the reactor. In order to facilitate sampling, a pipe joint can be used for connection. When the existing joint is connected to the pipeline, the joint is usually directly plugged into the pipeline without further processing the connection between the joint and the pipeline. The sealing of the connection is poor, and the joint is prone to loosening or even falling off, which may cause leakage of the reaction liquid. The skin of the staff may be contaminated with the sample. When the concentration of ammonia water is high, it is easy to cause skin irritation and burns, which endangers the health of the staff.

[0021] To solve the above defects of pipe joints in the sampling process, please refer to Figure 1-Figure 4The utility model provides a pipe joint for sampling and detecting the pH value of a molybdenum concentrate oxygen-pressure ammonia leaching reactor, which can improve the stability of the connection between the pipe and the joint, improve the sealing of the connection between the two, prevent the joint from falling off, avoid leakage of the reaction liquid, and protect the health of the staff. The device is based on the reactor body 1, and a liquid collection pipe 2 is arranged on the top of the reactor body 1. A liquid collection pipe 3 is installed on the liquid collection pipe 2, and the liquid collection pipe 3 is connected to the liquid collection pipe 2 through a connector 4. The liquid collection pipe 3 can be fixed on the liquid collection pipe 2 through the connector 4. A pipe valve is installed in the liquid collection pipe 2. The valve can be driven to guide the reaction liquid in the reactor body 1. The reaction liquid can be guided to an external collection container along the liquid collection pipe 2 and the liquid collection pipe 3, so as to complete the sampling of the reaction liquid. In order to enhance the stability of the connection between the liquid intake pipeline 2 and the connector 4 and ensure that the reaction liquid can smoothly enter the liquid intake pipe 3 from the liquid intake pipeline 2, a connecting ring 13, an inner sealing ring 10 and an outer sealing ring 5 are fixedly arranged in sequence from the inside to the outside inside the connector 4, an annular groove 6 for installing the inner sealing ring 10 is provided on the liquid intake pipeline 2, and a limiting ring 7 is fixedly installed on the outer wall of the inner sealing ring 10. Through holes 14 are provided on both sides of the liquid intake pipeline 2, and an anti-slip mechanism 8 for fixing the limiting ring 7 is provided in the through hole 14. The preliminary connection of the connector 4 can be completed by inserting the inner sealing ring 10 into the annular groove 6. After the connection, the inner sealing ring 10 can be limited by the cooperation of the anti-slip mechanism 8 and the limiting ring 7, thereby preventing the connector 4 from falling off from the liquid intake pipeline 2 and preventing the reaction liquid from leaking.

[0022] In order to achieve the preliminary fixation of the connecting head 4 and the liquid taking pipeline 2, a lead-out platform 9 is fixedly installed inside the liquid taking pipeline 2, and the connecting ring 13 is threadedly connected to the inner wall of the lead-out platform 9. After the inner sealing ring 10 is inserted into the ring groove 6, the connecting ring 13 corresponds to the lead-out platform 9. Continuing to rotate the connecting head 4 can install the connecting ring 13 in the lead-out platform 9, thereby completing the preliminary fixation of the connecting head 4 and the liquid taking pipeline 2.

[0023] In order to enhance the sealing performance when the liquid collection pipeline 2 and the connector 4 are connected, the height of the lead-out platform 9 is set smaller than the height of the liquid collection pipeline 2, and a sealing ring 12 adapted to the lead-out platform 9 is fixedly installed inside the connector 4. The sealing ring 12 is arranged between the inner sealing ring 10 and the connecting ring 13. After the connecting ring 13 is installed in the lead-out platform 9, the sealing ring 12 falls above the lead-out platform 9, and the connection between the connecting ring 13 and the lead-out platform 9 can be sealed. In combination with the inner sealing ring 10 and the outer sealing ring 5, the sealing performance of the liquid collection pipeline 2 and the connector 4 can be further improved to prevent leakage of the reaction liquid.

[0024] Since the threaded connection between the connecting ring 13 and the lead-out platform 9 may become loose, which may even cause the connector 4 to fall off in severe cases, in order to solve this technical problem, refer to Figure 3 and Figure 4As shown, the fixed rod 81 is fixedly installed on the outer wall of the liquid extraction pipeline 2, and a sliding rod 82 is slidably installed inside the fixed rod 81. The end of the sliding rod 82 is fixedly connected to an adapting block 83, and the end of the adapting block 83 is provided with a pressure slope 84. The bottom of the limiting ring 7 is provided with a pressure slope 11, and the slope of the pressure slope 11 is adapted to the slope of the pressure slope 84. The external fixed sleeve of the sliding rod 82 is provided with a connecting spring 85, and the connecting spring 85 is arranged between the fixed rod 81 and the adapting block 83. After the inner sealing ring 10 is inserted into the annular groove 6, as the connecting ring 13 rotates, The inner sealing ring 10 can continue to move downward in the annular groove 6 until the limiting ring 7 squeezes the adapting block 83, and the pressure-bearing slope 84 abuts against the pressure-applying slope 11, so as to squeeze the adapting block 83 to slide toward the fixing rod 81. At this time, the connecting spring 85 is deformed. When the limiting ring 7 slides down to the bottom of the adapting block 83, the pressure-bearing slope 84 can be reset by the elastic force of the connecting spring 85. At this time, the connecting spring 85 is above the limiting ring 7, and the limiting ring 7 can be automatically locked, thereby preventing the inner sealing ring 10 from falling off from the annular groove 6 and enhancing the stability of the connection between the liquid extraction pipeline 2 and the connector 4.

[0025] In order to facilitate the removal of the liquid intake pipe 3 from the liquid intake pipeline 2, magnet 1 86 is fixedly connected to both sides of the adaptation block 83, and magnet 2 87 is fixedly connected to both sides of the fixing rod 81. Magnet 1 86 and magnet 2 87 are opposite poles. By pulling the sliding rods 82 on both sides to merge magnet 1 86 and magnet 2 87, the adaptation block 83 can be removed from the limit ring 7, and the adaptation block 83 can be fixed by the magnetic force of magnet 1 86 and magnet 2 87, and then the connecting head 4 can be rotated to separate the connecting ring 13 from the lead-out platform 9, so that the liquid intake pipe 3 can be removed from the liquid intake pipeline 2.
