Description

Technical Field

[0001] This utility model belongs to the technical field of ultrapure ammonia processing, and in particular relates to a residual recovery box for ultrapure ammonia liquid distillation. Background Technology

[0002] Ultrapure ammonia is a key raw material for silicon nitride masking films in microelectronics. The processing of ultrapure ammonia requires distillation, a separation process that utilizes the different volatility of components in a mixture to separate them. After distillation, a significant amount of ultrapure ammonia liquid remains inside the distillation equipment, necessitating the use of residual recovery systems for its recycling. However, this system still has the following drawbacks in practical application:

[0003] When using the residual recovery tank, since there is no way to monitor the recovery capacity of ultrapure ammonia, the internal filtration structure of the recovery tank will not function properly when the internal capacity is insufficient.

[0004] When using a residual material recovery box, a filter structure is usually used. However, in order to facilitate the disassembly of the filter plate, the stability of the filter plate cannot be guaranteed. Therefore, it is impossible to ensure that the filter plate can simultaneously have the functions of stability and quick disassembly. Utility Model Content

[0005] The purpose of this invention is to provide a residual recovery box for ultrapure ammonia distillation. By rotating the cover plate to move the contact bar and using the float to move the measuring block, it solves the problem of avoiding excessive recovery of ultrapure ammonia, which would prevent normal filtration and allows for quick disassembly and installation of the filter plate.

A telescopic rod with its sliding part inside the telescopic hole is fixed to the end face of the measuring block. A rubber rod with its part inside the measuring tube is fixed to the end of the telescopic rod. A float ball is fixed to the lower end of the rubber rod.

[0010] Further, the entering pipe is fixedly connected to the left side of the box above the filter plate, and the discharging pipe is fixedly connected to the left side wall of the box below the measuring pipe.

[0011] Further, the end of the discharging pipe is spirally connected with a threaded cover, and the lower surface of the filter plate is fixedly connected with a baffle inserted into the inner position of the sealing groove.

[0012] Further, the surface of the floating ball is fixedly connected with a pull rope, and the lower end of the pull rope is fixedly connected with a counterweight.

[0013] Further, the front and rear sides of the box are both provided with a rotating hole at the right position of the taking and placing opening, and the front and rear sides of the cover plate are both fixedly connected with a rotating rod rotating at the inner position of the rotating hole.

[0014] Further, the middle position of the left side wall of the cover plate is fixedly connected with a handle rod.

[0016] The utility model has the following beneficial effects:

[0017] 1. When the ultra-pure ammonia liquid is recovered too much, the ultra-pure ammonia liquid pushes the ball to float upwards, so that the ball floats to the position of the telescopic hole, and then the ball cannot continue to move, at this time, the measuring plate moves to the maximum extent and cannot continue to move, so the staff can directly judge the height of the ultra-pure ammonia liquid, and the threaded cover is unscrewed, the ultra-pure ammonia liquid can be discharged in time, and the excessive recovery of the ultra-pure ammonia liquid is avoided, so that the normal filtration is ensured.

[0018] 2. When the filter plate is disassembled, the cover plate is rotated upwards through the handle rod, so that the cover plate opens the taking and placing opening, and the filter plate can be directly taken out in the box, so that the baffle is taken out in the sealing groove, and the cover plate pushes the abutting plate to push the filter plate through the pushing of the spring, so that the filter plate is stably positioned in the inner position of the box, and the quick disassembly and installation of the filter plate are realized.
