Description

TECHNICAL FIELD

[0001] The present application relates to a detection device, in particular a barium sulfide detector. BACKGROUND

[0002] Barium sulfide is an important chemical raw material. Barium sulfide is an important raw material for producing various barium salts (such as barium chloride, barium carbonate, barium nitrate, etc.). These barium salts are widely used in the ceramics, glass, electronics, metallurgy and other industries; barium sulfide can be used as a vulcanizing agent for rubber, promoting the cross-linking of rubber molecular chains, improving the strength, wear resistance and aging resistance of rubber.

[0003] Barium sulfide is usually white or light gray crystal, easily soluble in water, and hydrolysis will generate barium hydroxide and hydrogen sulfide gas when dissolved; barium sulfide aqueous solution is strongly alkaline and has corrosive properties, and contact with the skin or mucous membrane will cause burns. Barium sulfide is a highly toxic substance that can enter the human body through inhalation, ingestion or skin contact, causing symptoms of poisoning such as nausea, vomiting, abdominal pain, and difficulty breathing, and even life-threatening in severe cases.

[0004] Due to the above characteristics of barium sulfide, the water content in barium sulfide needs to be strictly controlled during production. Before the barium sulfide is shipped out, different batches of barium sulfide are sampled multiple times for water content testing to meet the shipping requirements. The current testing method is generally manual testing by the tester. The barium sulfide sample is placed in a sealed container, such as a flask, the flask is heated, and the mass change before and after heating is measured to calculate the water content. This operation needs to be repeated, which is inefficient, and there is a risk of gas leakage during this process, which can cause harm to the tester. CONTENT OF THE INVENTION

[0016] In order to make the above-mentioned purposes, features and advantages of the present new type more obvious and easy to understand, the specific embodiments of the present new type are described in detail below with reference to the drawings, so that the above-mentioned and other purposes, features and advantages of the present new type will be more clear. The same reference signs in all the drawings indicate the same parts. The drawings are not drawn to scale, and the emphasis is on showing the main idea of the present new type.

[0017] As shown in Figure 1 , the barium sulfide detector of the present new type can detect the barium sulfide before leaving the factory. The detector can complete the detection of multiple batches and multiple samples at one time, which includes a box body 1. A sealable detection tank 2 is placed in the box body 1. A leakage sensor 4 for detecting gas leakage can be further arranged inside the box body 1. The leakage sensor 4 is mainly used for detecting toxic and harmful gases that may leak. When detection is carried out by using the detection tank 2, toxic and harmful gases such as hydrogen sulfide may escape from the detection tank 2 due to poor sealing and other reasons. These gases can be detected by the leakage sensor 4.

[0018] An alarm 5 is arranged in the box body 1. The alarm 5 can be an audible and visual alarm, such as a loudspeaker, etc. The alarm 5 is connected with the leakage detection sensor 4. When leakage is detected, an alarm is given through the alarm 5. A communication interface 3 is installed on the outside of the shell of the box body 1. The communication interface 3 is connected with the leakage detection sensor 4. The leakage signal detected by the leakage detection sensor 4 can be sent to a remote monitoring computer through the communication interface 3.

[0019] The structure of the detection tank 2 is shown in Figure 2 . It includes a tank body 15 and an upper cover 6. A plurality of screw rods 16 can be arranged on the outside of the tank body 15. Correspondingly, a plurality of holes 9 for the screw rods 16 to pass through are arranged on the edge of the upper cover 6. After the screw rods 16 pass through the holes 9, nuts 8 are tightened on the screw rods 16, so that the upper cover 6 and the tank body 15 are tightly closed together. A pressure gauge 7 can be installed on the upper cover 6. The pressure gauge 7 is used to measure the pressure inside the detection tank 2.

[0020] The tank body 15 can be circular, hexagonal, square, etc. An outer support frame 13 and an inner support frame 11 are arranged in the tank body 15. The outer support frame 13 can be made of metal. The inner support frame 11 is located inside the support frame 13. The inner support frame 11 is integrally formed and has a plurality of independent cavities inside. These cavities are used to accommodate different detection units 10. The inner support frame 11 can be made of heat insulation material, for example, rock wool fibers, perlite powder, etc. can be mixed with a small amount of binder (such as phenolic resin, water glass), then put into a mold, extruded under a certain pressure (5-50 MPa) and temperature (room temperature or low temperature < 150℃), and then dried and solidified to form the inner support frame 11.

[0021] A control unit is provided at the bottom of the tank 15. The control unit is separated from the inner support frame 11 by a partition 12. The control unit is connected to the detection unit 10. The temperature of different detection units 10 can be controlled by the control unit, and the moisture content of barium sulfide in each detection unit 10 can be calculated.

[0022] like Figure 3 As shown, the detection unit 10 has an innermost sample cylinder 10.1. A heating wire 10.9 is wound around the outside of the sample cylinder 10.1, allowing the sample inside the sample cylinder 10.1 to be heated. The sample cylinder 10.1 can be made of a metal with good thermal conductivity, such as copper or aluminum, to improve the heating efficiency of the sample. An intermediate cylinder 10.2 is fitted over the sample cylinder 10.1. The intermediate cylinder 10.2 is made of a high-temperature resistant inorganic insulating material, such as ceramic, which has excellent high-temperature resistance and insulation properties. It can be alumina ceramic, magnesium oxide ceramic, aluminum nitride ceramic, etc. An outer cylinder 10.6 is fitted over the intermediate cylinder 10.2. The outer cylinder 10.6 can be made of stainless steel to ensure the structural strength of the detection unit 10 and increase its service life.

[0023] The intermediate cylinder 10.2 has an opening at the top to allow the sample cylinder 10.1 to be placed inside. The intermediate cylinder 10.2 has a bottom, on the inner side of which (facing the sample cylinder 10.1) are a temperature sensor 10.7 and a weight sensor 10.8. An interface module 10.3 is located on the outer side of the bottom. Cables supplying power to the heating wire 10.9, signal lines from the temperature sensor 10.7 and weight sensor 10.8 all pass through the bottom and connect to the interface module 10.3. A connection hole 10.10 is provided at the bottom of the outer cylinder 10.6, through which the wiring harness of the interface module 10.3 passes and connects to the control unit. The outer cylinder 10.6 may also have a bottom cover 10.5, which is fixed to the outer cylinder 10.6 by screws 10.4.

The signal plug can be connected to the communication interface 3 to send local measurement signals to a remote monitoring computer.

[0025] When detecting, a predetermined weight of barium sulfide is loaded in the detection bottle 17, different sampling points and different batches of barium sulfide can be loaded in each detection bottle 17, the sampling bottle 17 can be a ceramic bottle or a glass bottle, after completing the sampling and bottle loading, the detection bottle 17 is placed in different sample cylinders 10.1, the initial weight of the detection bottle 17 (containing barium sulfide) is read by the weight sensor 10.8, then the detection tank 2 is sealed and buckled, the upper cover 6 is covered on the tank body 15, and the nut 8 is tightened. Turn on the power, the control board controls the heating of the electric heating wire 10.9, the temperature in the different sample cylinders 10.1 is read by the temperature sensor 10.7, after the temperature reaches the set value, the temperature is kept for a predetermined time, so that the moisture in the barium sulfide can be fully volatilized, then the weight of the detection bottle 17 is read again by the weight sensor 10.8, at this time, due to the volatilization of water, the weight of the detection bottle 17 becomes lighter, and the water content of the barium sulfide can be calculated according to the difference between the two weights. During the detection process, if the detection tank 2 leaks, the leakage detection sensor 4 can detect the leakage and issue an alarm.

[0026] The barium sulfide detector of the new type is fully automatic, can detect multiple batches and multiple sampling points at a time, and greatly improves the detection efficiency; the detection process is carried out in a closed tank body, which can effectively avoid the leakage risk during the detection process and reduce the harm to the detection personnel.
