Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a liquid bromine dripping device. Background Technology

[0002] In some chemical production processes, bromine needs to be added periodically and quantitatively to specific reaction devices. Bromine is liquid at room temperature and is highly volatile. Commercially available bromine is usually packaged in small bottles (500g / bottle), and to prevent bromine volatilization, a water-sealed bottle is typically used. However, water needs to be separated before use. After water-bromine separation, the amount of pure bromine to be added is weighed according to process requirements. This process is overly complex and time-consuming. Furthermore, because bromine is volatile and its volatile gases are toxic, the process can lead to liquid bromine volatilization, harming the operator's health. Therefore, a convenient device for adding liquid bromine is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a liquid bromine dripping device to solve the problems mentioned in the background art.

[0004] A liquid bromine dropping device is characterized by comprising an isolator, an operating glove on the isolator, an exhaust pipe at the top of the isolator connected to a waste gas treatment device, an exchange chamber inside the isolator, a weighing module inside the isolator, a glass separator fixedly connected to the weighing module, and a conduit at the bottom of the glass separator connected to a reaction vessel.

[0005] Preferably, the exhaust pipe is equipped with an air valve.

[0006] Preferably, the exchange chamber has two openings, and a first sealing door and a second sealing door are respectively provided at the two openings. The first sealing door separates the exchange chamber from the outside of the isolator, and the second sealing door separates the exchange chamber from the inside of the isolator.

[0007] Preferably, the top of the glass separator is provided with a rotating end cap, and the bottom of the glass separator is provided with a discharge valve, which is connected to a conduit.

[0008] Preferably, the conduit is provided with a three-way tube, and a sight glass is provided on the side of the three-way tube near the glass separator. The other two ports of the three-way tube are respectively provided with an inlet valve and a drain valve.

[0009] Preferably, the weighing module is electrically connected to a display screen.

[0010] Preferably, the isolator is a transparent box.

[0011] Preferably, the first sealing door opens outwards, and the second sealing door opens inwards.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This utility model includes a transparent isolator, with an exchange chamber fixedly installed on the inner casing of the isolator. The exchange chamber has two sealing doors, wherein the first sealing door controls the connection and sealing between the outside of the isolator and the inside of the exchange chamber, and the second sealing door controls the connection and sealing between the isolator and the exchange chamber. By alternately opening and closing the first and second sealing doors, the leakage of air inside the isolator can be minimized while transferring bottled liquid bromine to the exchange chamber connected to the isolator. The isolator is equipped with operating gloves, which allow for operation of the inside of the isolator from the outside. The operation effectively reduces workers' contact with volatile bromine, protecting their health. The alternating opening and closing of the two sealed doors also effectively prevents air from escaping from the isolator, further protecting workers' health and avoiding air pollution. The isolator is equipped with a glass separator, allowing for a more direct observation of the remaining liquid bromine. A three-way valve is installed on the conduit, with a sight glass at the front end, enabling precise observation of the exact position of the remaining liquid bromine in the conduit. The inlet valve can be closed in time before water passes through the valve, and all water in the glass separator can be discharged through the drain valve in the three-way valve.

[0013] The top of the isolator is connected to an exhaust pipe, which is connected to a waste gas treatment device to purify the air, remove liquid bromine from the air, and prevent liquid bromine from harming human health.

[0014] The glass separator is directly mounted on the weighing module, which can display the weight of the glass separator in real time, thereby obtaining the mass of the liquid bromine flowing out, facilitating precise control of the process flow and ensuring product quality.

[0015] This device can be operated quickly without causing pollution to the operator, making it highly convenient; it is also highly safe with minimal environmental pollution and harm to personnel. Attached Figure Description

Detailed Implementation

[0018] The following will describe specific embodiments and appendices. Figure 1 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0019] A liquid bromine dripping device includes an isolator 1, which is a transparent box made of tempered glass or transparent plastic sheet laminated together, allowing easy observation of the interior from the outside. An exchange chamber 2 is provided inside the isolator 1, fixedly mounted on one side of the isolator 1. The exchange chamber 2 has a cuboid structure with two openings at both ends. One end of the exchange chamber 2 is fixedly connected to the isolator 1, and the exchange chamber 2 penetrates the sealed chamber and communicates with the outside. A first sealing door 21 and a second sealing door 22 are respectively provided at the openings at both ends of the exchange chamber 2. The first sealing door 21 separates the exchange chamber 2 from the outside of the isolator 1, and the second sealing door 22 separates the exchange chamber 2 from the interior of the isolator 1. When transferring the liquid bromine bottle into the isolator 1, the leakage of air from the isolator 1 can be minimized. This is because the liquid bromine needs to be opened and circulated inside the isolator 1, which inevitably leads to its evaporation. In specific use, the first sealing door 21 should be opened first, and the sealed liquid bromine bottle should be placed into the exchange chamber 2. Then, the first sealing door 21 should be closed, and then the second sealing door 22 should be opened from the inside of the isolator 1. The first sealing door 21 opens outward, and the second sealing door 22 opens inward, so that the first sealing door 21 needs to be opened from the outside of the isolator 1, and the second sealing door 22 needs to be opened from the inside of the isolator 1. This operation can minimize the leakage of air from the isolator 1 into the exchange chamber 2, reducing the harm to external operators.

[0020] The isolator 1 is equipped with an operating glove 11, which is a rubber glove. Two operating holes are provided on the isolator 1. The cuffs of the rubber gloves are fixedly connected to the operating holes, allowing the staff to put their hands into the isolator 1 from the outside through the operating holes and directly wear the rubber gloves to operate inside the isolator 1. This isolates the staff from the environment where liquid bromine is processed, and can fully ensure that the staff will not inhale the volatile liquid bromine.

[0021] The isolator 1 is equipped with an exhaust pipe 12 at its top, and an exhaust valve 13 is provided on the exhaust pipe 12. The exhaust pipe 12 is connected to a waste gas treatment device. The waste gas treatment device is existing technology and can purify bromine gas and eliminate the toxicity of the exhaust air.

[0022] The isolator 1 also contains a weighing module 3, which is existing technology. The weighing module 3 is electrically connected to a display screen 31, located on the operating platform in the production workshop. The display screen 31 allows production staff to visually monitor the amount of liquid bromine used and assess the reaction progress. A glass separator 4 is fixedly connected to the weighing module 3. The glass separator 4 is used to hold liquid bromine with a water seal. Water and liquid bromine can be introduced together. After standing, the liquid bromine and water will clearly separate into layers, with the liquid bromine located at the bottom of the glass separator 4. The part is equipped with a conduit 5, which is connected to the glass separator 4. The other end of the conduit 5 is connected to the reaction vessel 6. The bottom end of the glass separator 4 is equipped with a discharge valve 42. The glass separator 4 is connected to the conduit 5 through the discharge valve 42. The liquid inside the glass separator 4 can flow out from the discharge valve 42. The discharge valve 42 is existing technology and can use common valve bodies, such as solenoid valves, which can be easily remotely controlled. The top of the glass separator 4 is equipped with a rotating end cap 41, which can be flipped open to facilitate the addition of liquid bromine to the glass separator 4.

[0023] A three-way pipe 51 is also provided on the conduit 5. The three-way pipe 51 has three ports, namely the liquid inlet end, the first liquid outlet end, and the second liquid outlet end. The liquid inlet end is connected to the conduit 5 near the glass separator 4. The liquid inlet end is provided with a sight glass 52. The sight glass 52 is transparent and can be used to directly observe the color of the liquid flowing through it. The end near the reactor 6 is provided with an inlet valve 53. When water is observed flowing from the glass separator 4 into the conduit 5 through the sight glass 52, the inlet valve 53 can be closed to maximize the flow of the remaining liquid bromine into the reactor 6, which is beneficial to saving raw materials. The other end, which is not connected to the conduit 5, is provided with an evacuation valve 54, which can drain the remaining water in the glass separator 4 for convenient subsequent use.

[0024] This device is fast and convenient to operate, allowing for easy operation while isolating personnel from liquid bromine, ensuring high safety and maximizing the safety of personnel.
