Description

Technical Field

[0001] The utility model relates to the technical field of degassing towers, in particular to a degassing tower for producing 5-methyltetrazolyl. Background Art

[0002] The existing degassing tower used to produce 5-methyltetrazolyl mainly includes a tower body, and a nozzle is used to spray the absorption liquid onto the tower plate. The absorption liquid seeps through the tower plate and is discharged through the bottom; the air used to remove the hydrazoic acid gas enters the degassing tower by utilizing the negative pressure formed in the pipeline. In the degassing tower, the air contacts the absorption liquid. Due to the effect of the tower plate, the absorption liquid is dispersed into many small streams or water droplets, forming gas-liquid convection mass transfer with the air to remove the hydrazoic acid gas.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing degassing tower for the production of 5-methyltetrazole does not have a good automatic opening and closing function of the air pump and the liquid pump. Since the absorption liquid is discharged through the through holes of the tower plate at a limited speed, accumulation will be formed, and the caretaker needs to regularly open and close the air pump and the liquid pump, which has high labor costs and is not opened and closed in time. Therefore, improvement is urgently needed. Therefore, we propose a degassing tower for the production of 5-methyltetrazole. Utility Model Content

[0004] The utility model aims to provide a degassing tower for producing 5-methyltetrazolyl, which solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a degassing tower for the production of 5-methyltetrazolyl, comprising a tower body, the top of the tower body is connected to a gas outlet, the bottom of one side of the tower body is connected to an air inlet pipe, and the other side of the tower body is provided with a liquid inlet pipe;

[0006] A tower plate is fixedly installed in the middle of the tower body, and a base is fixedly installed at the bottom of the tower body;

[0007] The two ends of the liquid inlet pipe respectively penetrate the top and bottom of the tower body, the top of the liquid inlet pipe is connected to a nozzle, and there are two groups of nozzles, and a liquid pump is fixedly installed in the middle of the liquid inlet pipe;

[0008] A servo motor is fixedly installed on one side of the liquid inlet pipe close to the nozzle, a brush plate is fixedly installed on the bottom of the transmission shaft of the servo motor, and a brush is fixedly installed on the top of the brush plate;

[0009] A horizontal plate is fixedly installed on the inner wall of one side of the tower body near the upper side of the tower plate, a movable rod is movably penetrated in the middle of the horizontal plate, a floating block is fixedly installed at the bottom end of the movable rod, and a stopper is fixedly installed at the top end of the movable rod;

[0010] A push-delay switch is fixedly installed on the front side of the horizontal plate, and the block presses against the upper side of the movable button of the push-delay switch. The signal output end of the push-delay switch is respectively connected to the signal input end of the air pump and the liquid pump, and can be used in combination with components such as the push-delay switch, the float block and the movable rod. During the use of the degassing tower for the production of 5-methyltetrazole, when the absorption liquid is gradually accumulated on the tower plate, the liquid causes the float block to gradually move up. When the block no longer squeezes the button of the push-delay switch, it means that there is too much absorption liquid on the tower plate. After a period of time, the air pump and the liquid pump stop operating, and the absorption liquid is discharged through the through holes of the tower plate. When it is at a certain liquid level, the block re-pressurizes the movable button. After a certain period of time, the air pump and the liquid pump restart. In this way, the liquid volume is controlled in a cycle to prevent the tower plate from being damaged by excessive pressure for a long time, thereby improving its service life.

[0011] As an optional scheme of the technical solution of the present application, a protrusion is fixedly installed on the upper side of the tower body close to the horizontal plate, and a proximity delay switch is fixedly installed on the bottom of the protrusion, and the signal output end of the proximity delay switch is connected to the signal input end of the servo motor, which can be used in conjunction with components such as the proximity delay switch and the servo motor. Whenever the block moves up to a certain position, the proximity delay switch is energized for a certain period of time, during which the servo motor can drive the brush plate to rotate, and the brush of the brush plate cleans the spray hole of the nozzle, thereby realizing intermittent cleaning of the nozzle, thereby reducing the frequency of manual entry into the tower for cleaning.

[0012] As an optional solution of the technical solution of the present application, a battery is fixedly installed on one side of the tower body close to the liquid pump. The battery is electrically connected to the press delay switch and the proximity delay switch through wires. The battery can provide electrical energy, so there is no need to pull too long wires, thereby reducing the cost required for power supply.

A detachable external pipeline can be connected through the connecting flange and its positioning holes, which meets the needs of later pipeline replacement and maintenance.

A sealing ring is fixedly installed in the wire hole, which can provide a protective effect through the cover body, and the wire is passed through the wire hole, and the gap between the wire hole and the wire is filled through the sealing ring.

[0016] 1. The utility model discloses a degassing tower for producing 5-methyltetrazole, which is provided with a push-delay switch, a floating block and a movable rod. When the degassing tower for producing 5-methyltetrazole is used, when absorption liquid is gradually accumulated on the tower plate, the liquid causes the floating block to gradually move upward. When the block no longer presses the button of the push-delay switch, it means that there is too much absorption liquid on the tower plate. After a period of time, the air pump and the liquid pump stop running, and the absorption liquid is discharged downward through the through hole of the tower plate. When the liquid level reaches a certain level, the block re-pressurizes the movable button. After a certain period of time, the air pump and the liquid pump restart. In this way, the liquid amount is controlled in a cycle to prevent the tower plate from being damaged by excessive pressure for a long time, thereby improving its service life.

Whenever the block moves up to a certain position, the proximity delay switch is energized for a certain period of time. During this period, the servo motor can drive the brush plate to rotate. The bristles of the brush plate clean the spray holes of the nozzle, thereby realizing intermittent cleaning of the nozzle and reducing the frequency of manual cleaning in the tower.

When the stopper 64 no longer presses the button of the push-delay switch 61, it means that there is too much absorption liquid on the tower plate 11. After a period of time, the air pump 71 and the liquid pump 31 stop running, and the absorption liquid is discharged downward through the through hole of the tower plate 11. When it reaches a certain liquid level, the stopper 64 re-presses the movable button. After a certain period of time, the air pump 71 and the liquid pump 31 are restarted, and the liquid volume is controlled in this cycle to prevent the tower plate 11 from being damaged by excessive pressure for a long time, thereby improving its service life.
