Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figs. 1-6 As shown in the figure, this embodiment proposes a fiberglass apparatus for producing hydrobromic acid, including a fiberglass tank 1.

A discharge pipe 5 is fixedly connected to the bottom of the fiberglass tank 1. A motor 6 is fixedly installed on the top of the sealing cover 3. A support frame 2 is fixedly connected to the outside of the fiberglass tank 1. A control box 10 is fixedly connected to the outside of the support frame 2. A motor switch electrically connected to the motor 6 is provided on the control box 10. A drive shaft 7 is fixedly connected to the output shaft of the motor 6. A negative pressure suction mechanism 8 is provided at the top of the inner side of the fiberglass tank 1, which, in conjunction with the rotation of the drive shaft 7, draws hydrobromic acid gas into an alkaline washing tower. A stirring mechanism 9 is provided at the bottom of the drive shaft 7, which, in conjunction with the rotation of the drive shaft 7, stirs the material.

[0029] By starting the motor 6, the drive shaft 7 is driven to rotate, which causes the stirring mechanism 9 to stir the material and make it fully mixed. At the same time, the negative pressure extraction mechanism 8 can extract the volatile hydrobromic acid gas and introduce it into the alkaline washing tower for neutralization treatment. This can prevent the hydrobromic acid gas from accumulating inside the fiberglass tank 1, which would increase toxicity and corrosiveness. It can also ensure that the inside of the fiberglass tank 1 is under negative pressure to prevent the leakage of hydrobromic acid gas.

[0030] Further, the negative pressure air extraction mechanism 8 comprises a cylinder body 81 fixedly connected to the top of the sealing cover 3 and communicating with the inside of the glass steel tank body 1, a suction impeller 82 rotatably connected to the inner side of the cylinder body 81, a gas guide pipe 83 fixedly connected to the top of the cylinder body 81 and communicating with the caustic lye washing tower, and a transmission member arranged at the bottom of the sealing cover 3 and driven to rotate the suction impeller 82 by cooperating with the rotation of the driving shaft 7.

The tooth number ratio of the gear one 86 to the gear two 87 is 1:10.

[0031] By starting the motor 6 to drive the driving shaft 7 to rotate, the gear two 87 is driven to rotate. Since the gear one 86 is engaged with the gear two 87 and the tooth number ratio of the two is 1:10, the gear one 86 rotates at a high speed, so that the suction impeller 82 rotates at a high speed, thereby reducing the pressure at the inlet end of the cylinder body 81, so that the hydrogen bromide gas in the glass steel tank body 1 is sucked into the inside of the cylinder body 81 and introduced into the caustic lye washing tower through the gas guide pipe 83 for neutralization treatment, thereby ensuring that the inside of the glass steel tank body 1 is in a negative pressure state to avoid the problem of hydrogen bromide gas leakage.

One end of each of the elastic rods 942 is fixedly connected to a scraper 943 abutting against the inner wall of the glass steel tank body 1.

[0033] By starting the motor 6 to drive the driving shaft 7 to rotate, the connecting shaft 91 is driven to rotate synchronously, the bracket 92 drives the helical blades 93 to rotate, so that the helical blades 93 stir the materials and make the materials fully mixed. At the same time, the elastic rods 942 drive the scrapers 943 to move circumferentially along the inner wall of the glass steel tank body 1, so that the scrapers 943 scrape off the materials attached to the inner wall of the glass steel tank body 1, thereby reducing the difficulty of subsequent cleaning and reducing the corrosive effect on the inner wall of the glass steel tank body 1.

[0034] Further, the elastic rod 942 comprises a sleeve joint part 9421, one end of the sleeve joint part 9421 is fixedly connected with the mounting seat 941, the other end of the sleeve joint part 9421 is inserted with a plug-in part 9422, the inner side of the sleeve joint part 9421 is slidably connected with a sliding block 9423, one end of the sliding block 9423 is fixedly connected with the plug-in part 9422, the inner side of the sleeve joint part 9421 is sleeved with a spring 9424, one end of the spring 9424 abuts against the sliding block 9423, the other end of the spring 9424 abuts against the inner wall of the sleeve joint part 9421. The design of the spring 9424 can dynamically compensate the scraper 943, so that the scraper 943 is always attached to the inner wall of the glass steel tank body 1 after wear, and the stability of the cleaning of the scraper 943 is ensured.

[0035] Working principle: first, the material is introduced into the glass steel tank body 1 through the feeding pipe 4, then the motor 6 is started to drive the driving shaft 7 to rotate, so that the connecting shaft 91 rotates synchronously, the support 92 drives the spiral blade 93 to rotate, so that the spiral blade 93 stirs and fully mixes the material, at the same time, the elastic rod 942 drives the scraper 943 to move circumferentially along the inner wall of the glass steel tank body 1, so that the scraper 943 scrapes the material attached to the inner wall of the glass steel tank body 1, reducing the difficulty of subsequent cleaning;

[0036] At the same time, the driving shaft 7 drives the gear two 87 to rotate, since the gear one 86 and the gear two 87 are engaged and the tooth number ratio of the two is 1:10, the gear one 86 rotates at a high speed, so that the suction impeller 82 rotates at a high speed, thereby reducing the pressure at the inlet end of the cylinder 81, so that the hydrogen bromide gas in the glass steel tank body 1 is sucked into the cylinder 81 and introduced into the alkali washing tower through the gas guide pipe 83 for neutralization treatment, thereby ensuring that the glass steel tank body 1 is in a negative pressure state to avoid the problem of hydrogen bromide gas leakage.
