Description

Analytical measuring device for ammonium fluoride production

Technical Field

The invention relates to the technical field of ammonium fluoride production, in particular to an analysis and determination device for ammonium fluoride production.

Background technique

Ammonium fluoride is widely used and is an important chemical material. It is an ionic compound that is insoluble in ethanol but soluble in water. It is mainly formed by the neutralization of anhydrous hydrofluoric acid and liquid ammonia. Leakage of large amounts of liquid ammonia can lead to a series of accidents, such as poisoning, explosion, burns, fire, and frostbite.

In the prior art, when liquid ammonia is transported, the pipeline will leak to a certain extent due to the long-term transportation, and ammonia is a colorless gas. When the on-site monitoring equipment detects that the toxic gas is leaking and the concentration exceeds the standard, it will prompt the personnel to leave or take corresponding measures, but the system's response speed in taking emergency measures is slow; in addition, in the prior art, although the personnel were evacuated urgently, the leakage continued and could not be sealed in time, which caused great economic losses to the manufacturer to a certain extent, and the strong toxic and irritating odor would cause harm to the human body. In addition, it would also cause certain difficulties to the maintenance work during the subsequent maintenance; furthermore, although the alarm system would sound an alarm, it would take time for the crowd to evacuate, and there were no effective countermeasures in the prior art during this period.

Therefore, we proposed an analytical measuring device for ammonium fluoride production to solve the above problems.

technical problem

In view of the deficiencies in the prior art, the present invention provides a multifunctional analytical and measuring device for ammonium fluoride production, which can detect gas leakage in the first time when it occurs, rather than issuing an alarm only when the concentration reaches a certain value; and can seal the gas while issuing an alarm; and can preliminarily process the leaked gas according to its chemical properties, thereby reducing poisoning and minimizing casualties, so as to solve the problems raised in the above-mentioned background technology.

Technical Solutions

To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an analysis and determination device for ammonium fluoride production, comprising a pipeline, a detection component is arranged on the outer periphery of the pipeline, a plugging component is arranged on the detection component, and a spraying component is arranged on one side of the plugging component; a flat plate is arranged in the detection component, an auxiliary plate is arranged on the flat plate, a vertical block is fixedly connected to the auxiliary plate, a circular opening is opened on the vertical block, a rope is inserted in the circular opening, a trigger column cavity is arranged on the same vertical surface of the rope, one end of the rope in the trigger column cavity is fixedly connected to a first magnet, the other end of the rope in the trigger column cavity is fixedly connected to a second magnet, and a magnetic switch is arranged on the side of the first magnet away from the second magnet and located at one end of the inner wall of the trigger column cavity.

Preferably, a fixed block is provided in the sealing component, the fixed block is fixedly connected with an annular cavity, a push column is inserted in the annular cavity, a special-shaped sliding block is slidably connected in the annular cavity, and a notch is formed at the upper end of the special-shaped sliding block.

Preferably, an alarm is provided on the surface of the annular cavity, and a first spring is provided between the pipeline and the annular cavity.

Preferably, an elastic buckle is provided on the inner cavity of the annular cavity, a through hole is opened on the special-shaped sliding block, and a second spring is provided on the special-shaped sliding block.

Preferably, an air pipe is plugged into the annular cavity, a ventilation block is plugged into the annular cavity, a moving block is plugged into the lower end of the ventilation block, and a connecting rod is fixedly connected to the bottom end of the moving block.

Preferably, a fixing plate is fixedly connected to the flat plate, a first electrical contact is arranged on the bottom surface of the fixing plate, a second electrical contact is arranged below the first electrical contact, and a third spring is arranged between the pipe and the fixing plate.

Preferably, an annular water trough is arranged on the side of the annular cavity, a water outlet is opened on the annular water trough, and a water pipe is inserted into the annular water trough.

Preferably, a telescopic rod is provided on the inner side surface of the annular water tank, and a sealing piece is fixedly connected to one end of the telescopic rod.

Preferably, the trigger column cavity is fixed on the fixing block via a column rod.

Preferably, there is an electrical connection between the telescopic rod and the first electrical contact and the second electrical contact.

Beneficial Effects

Compared with the prior art, the present invention provides an analytical measuring device for ammonium fluoride production, which has the following beneficial effects: 1. In the present invention, as the vertical block expands, the first magnet and the second magnet located in the trigger column cavity will move away from each other during this expansion period, wherein the first magnet will gradually approach the magnetic switch arranged on the inner wall of the trigger column cavity. When the distance is close, the magnetic switch will control the alarm electrically connected to it to sound an alarm, thereby reminding the staff that the gas is leaking. This setting is different from the untimely nature of the existing concentration detection equipment, and can sound an alarm in time to prompt personnel to leave or take corresponding measures, and the reaction speed is relatively fast; 2. In the present invention, under the action of the air pump, the gas will enter the annular cavity through the air pipe, and enter the ventilation block with the assistance of the through hole. As the gas enters, the gas will move downward against the moving block and the auxiliary plate fixedly connected to its bottom end by the connecting rod, that is, the auxiliary plate moving downward at this time will press the flat plate originally pushed open by the leaked gas, that is, the setting of the sealing component can be used in the gas. The initial plugging work is carried out at the first time when the plate is lifted up when leakage occurs, which not only reduces the economic losses of the manufacturer to the greatest extent, but also reduces the difficulty of subsequent maintenance because the leakage of ammonia with a strong irritating odor is less. 3. In the present invention, when the plate is lifted up, the first electrical contact and the second electrical contact that were originally in contact will be separated. At this time, the water pump arranged at one end of the water pipe will transport water, and the telescopic rod electrically connected to the first electrical contact and the second electrical contact will also bring the plugging sheet to release the blockage of the water outlet. At this time, water will spray out from the water outlet. Due to the property that ammonia is easily soluble in water, part of the leaked ammonia will be dropped to the ground by the sprayed water belt, so the gas in the air will be relatively less at this time. This setting can reduce the amount of inhalation by personnel and minimize casualties. 4. In the present invention, when the plate is lifted up by the leaking gas, the detection component, the plugging component and the spraying component are all triggered. This setting that works at the first time of gas leakage can reduce leakage to a minimum and minimize damage.

Working process and principle: In the initial state: the flat plate 201 is tightly attached to the surface of the pipe 1 under the action of the first spring 211, the first magnet 207 and the second magnet 208 are adsorbed, the connecting port between the air pipe 309 and the annular cavity 302 is blocked by the right end of the special-shaped sliding block 304, and the first electrical contact 402 and the second electrical contact 403 are in contact.

The following is the working process of the detection component 2: Liquid ammonia is a colorless liquid. For the convenience of transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. When the pipeline 1 that transports it ruptures, the pressurized liquid ammonia will return to the gaseous state under the action of air pressure. At this time, the impact force of the ammonia leaked from the pipeline is relatively large.

During use, if the pipeline 1 leaks, the gas leaking from the pipeline 1 will lift the plate 201 on the surface of the pipeline 1. At this time, the first spring 211 is compressed, and the lifted plate 201 will expand outward with the pipeline 1 as the center through the auxiliary plate 202 and the vertical block 203 thereon during the upward movement. Since the length of the rope 205 is fixed, as the vertical block 203 expands, the first magnet 207 and the second magnet 208 located in the trigger column cavity 206 will move away from each other during this expansion period, and the first magnet 207 will gradually approach the magnetic switch 209 provided on the inner wall of the trigger column cavity 206. When the distance is close, the magnetic switch 209 will control the alarm 210 electrically connected to it to alarm, so as to remind the staff that the gas has leaked. This setting is different from the untimely nature of the existing concentration detection equipment. It can timely alarm to prompt personnel to leave or take corresponding measures, and the reaction speed is relatively fast. Please refer to Figures 1 to 5 for the above working process.

The following is the working process of the blocking component 3: Furthermore, when the flat plate 201 is lifted up by the gas leaking in the pipeline 1 to make the detection component 2 work, the push pin 303 fixed on the flat plate 201 will move upward in the annular cavity 302, please refer to Figure 8, at this time, the connecting rod 312 on the auxiliary plate 202 will move upward in the ventilation block 310 with the moving block 311 thereon, and further, as the push pin 303 moves upward, the push pin 303 will push the shaped sliding block 304 to move to the left through the inclined surface of the shaped sliding block 304. In this process, the right end of the shaped sliding block 304 will gradually release the blockage of the connecting port between the trachea 309 and the annular cavity 302, and because the magnetic switch 209 will also have an electrically connected relationship when controlling the alarm 210, the position The air pump at one end of the air pipe 309 is turned on, so at this time, under the action of the air pump, the gas will enter the annular cavity 302 through the air pipe 309, and enter the ventilation block 310 with the assistance of the through hole 307. As the gas enters, the gas will move downward against the moving block 311 and the auxiliary plate 202 fixedly connected to its bottom end by the connecting rod 312, that is, the auxiliary plate 202 moving downward at this time will press the flat plate 201 that was originally pushed open by the leaking gas, that is, through the setting of the blocking component 3, preliminary blocking work can be performed at the first time when the gas leaks and lifts up the flat plate 201, which not only reduces the economic losses of the manufacturer to the greatest extent, but also reduces the difficulty of subsequent maintenance due to the less leakage of ammonia with a strong irritating odor; please refer to Figures 6 to 11 for the above working process.

The following is the working process of the spray assembly 4: Furthermore, when the flat plate 201 is pushed upward, the first electrical contact 402 and the second electrical contact 403 that were originally in contact will separate, and at this time, the water pump set at one end of the water pipe 407 will transport water, and the telescopic rod 408 that is electrically connected to the first electrical contact 402 and the second electrical contact 403 will also bring the blocking piece 409 to release the blocking of the water outlet 406, and at this time, water will be sprayed out from the water outlet 406. Due to the property that ammonia is easily soluble in water, part of the leaked ammonia gas will be dropped to the ground by the sprayed water belt, so the gas in the air will be relatively less at this time. This arrangement can reduce the amount of inhalation by personnel and minimize casualties; please refer to Figures 8, 12 to 13 for the above working process.

Furthermore, when the flat plate 201 is lifted up by the leaking gas, the detection component 2, the blocking component 3 and the spraying component 4 are all triggered. This setting that works at the first moment of gas leakage can minimize the leakage and the damage.

By setting up the detection component 2, the gas leakage in the pipeline 1 can be detected in the first time, and with the assistance of the blocking component 3, the leakage part can be preliminarily blocked, and the inhalation amount of personnel can be reduced under the action of the spray component 4, which can minimize casualties.
