Description

Technical Field

[0001] This utility model relates to the field of exhaust gas technology, and in particular to an exhaust gas treatment device for the extraction and production process of bile acid products. Background Technology

[0002] Bile acid products are a class of organic acid substances with a steroidal nucleus structure that are extracted, purified, or biosynthesized from animal bile.

[0003] When producing bile acid products, decompression, concentration, and drying processes generate exhaust gases containing impurities. Currently, the treatment of such exhaust gases often employs a combination of filtration and purification processes. However, during the filtration process, the long-term accumulation of impurities in the exhaust gas can clog the filter screen, leading to a reduction in filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tail gas treatment device for the extraction and production process of bile acid products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tail gas treatment device for the extraction and production process of bile acid products includes a treatment tank. A fixing plate is fixedly connected to the bottom of the treatment tank through an installation groove, and a cover plate is provided at the top of the treatment tank. A drive shaft is rotatably connected inside the cover plate. Multiple stirring paddles are fixedly installed on the surface of the drive shaft, and brushes are fixedly installed on the inner side of the stirring paddles.

[0007] Multiple mounting posts are fixedly installed on the top of the fixed plate. Pressure sensors are installed inside the mounting posts, and a filter screen is movably connected to the top of the mounting posts via a spring. The outer side of the filter screen contacts the inner side of the brush, and the spring is located outside the pressure sensor.

[0008] In addition, a preferred structure is that a scraper is fixedly installed on one side of the stirring paddle.

[0009] In addition, a preferred structure is that a drain outlet is provided at the bottom of the treatment tank.

[0010] In addition, a preferred structure is that the drive shaft is driven by a motor, which is located at the top of the cover plate.

[0011] In addition, a preferred structure is that a limiting groove is provided at the top of the filter screen, and the limiting groove is rotatably connected to the bottom of the drive shaft.

[0012] In addition, a preferred structure is that a sealing strip is adhered to the bottom of the cover plate, and the sealing strip is located inside the processing tank.

[0013] Furthermore, the preferred configuration is that the pressure sensor is model PX409-250GI.

[0014] The beneficial effects of this utility model are as follows: by setting a brush, impurities on the filter screen can be removed during the exhaust gas impurity treatment process, thereby preventing the filter screen from being clogged due to the accumulation of impurities during long-term use, and thus improving the filtration efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6A tail gas treatment device for the extraction and production process of bile acid products includes a treatment tank 1 and a fixed plate 2. The fixed plate 2 is fixedly connected to the bottom of the inner wall of the treatment tank 1 through a mounting groove 11. A cover plate 12 is bolted to the top of the treatment tank 1. A sealing strip 19 is adhered to the bottom of the cover plate 12 and is located inside the treatment tank 1. A drive shaft 13 is rotatably connected inside the cover plate 12. The drive shaft 13 is driven by a motor 17 located at the top of the cover plate 12. Multiple stirring paddles 14 are fixedly installed on the surface of the drive shaft 13 and are located inside the treatment tank 1. A brush 15 is fixedly installed on the inner side of the stirring paddle 14 and a scraper 16 is fixedly installed on one side of the stirring paddle 14. The bottom of the scraper 16 contacts the bottom of the inner wall of the treatment tank 1. In addition, a drain port 18 is opened at the bottom of the treatment tank 1.

[0024] Multiple mounting posts 22 are fixedly installed on the top of the fixed plate 2. Pressure sensors 24 are installed inside the mounting posts 22. The pressure sensors 24 are model PX409-250GI. A filter screen 21 is movably connected to the top of the mounting posts 22 through a spring 23. The outer side of the filter screen 21 contacts the inner side of the brush 15. The spring 23 is located outside the pressure sensor 24. A limit groove 25 is provided at the top of the filter screen 21. The limit groove 25 is rotatably connected to the bottom of the drive shaft 13.

[0025] In this embodiment, during use, exhaust gas containing impurities is transported into the treatment tank 1 through the air inlet on the front side of the treatment tank 1. Then, the exhaust pipe at the bottom of the treatment tank 1 is connected to the purifier through a pump and pipeline. The pump is then started, and the exhaust gas in the treatment tank 1 will be suctioned through the filter screen 21 and enter the exhaust pipe from the bottom of the filter screen 21 and the exhaust hole on the fixing plate 2. It is then transported to the purifier for purification through the pump and pipeline. During the process of the exhaust gas passing through the filter screen 21, the impurities in the exhaust gas will be adsorbed on the outer surface of the filter screen 21, thereby achieving the filtration of the exhaust gas.

[0026] After processing exhaust gas for an extended period, numerous impurities from the exhaust gas are adsorbed onto the filter screen 21. At this time, the weight of the filter screen 21 increases as the impurities accumulate. When the impurities reach a certain weight, the filter screen 21 moves downwards due to the weight of the impurities, thereby causing the spring 23 at the bottom to compress on the mounting column 22. Subsequently, the bottom of the filter screen 21 touches the pressure sensor 24. At this time, the motor 17 starts, thereby driving the transmission shaft 13 to rotate. The transmission shaft 13 drives multiple agitators 14 on the surface to rotate, and the agitators 14 drive the brush 15 to rotate, thereby cleaning the impurities on the surface of the filter screen 21. The cleaned impurities fall to the bottom of the inner wall of the treatment tank 1, and are pushed by the scraper 16 on one side of the agitator 14, and stored in the sludge hopper through the drain port 18.

[0027] After the impurities are removed, the filter screen 21 will be lifted by the spring 23 at the bottom due to the weight of the impurities, thus separating the bottom of the filter screen 21 from the pressure sensor 24. At this time, the motor 17 will not stop rotating immediately, but will continue to run for a period of time before stopping to prevent the sludge at the bottom of the treatment tank 1 from not being completely cleaned. After the motor 17 stops rotating, the negative pressure drain pipe at the bottom of the sludge hopper can be activated to clean the impurities in the sludge hopper. In addition, during the rotation, the installation groove 11, the fixing plate 2, and the limiting groove 25 can prevent the filter screen 21 from being displaced due to the force of the stirring paddle 14 during the rotation, and the sealing strip 19 at the bottom of the cover plate 12 can prevent the exhaust gas in the treatment tank 1 from leaking.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
