Description

Technical Field

[0001] This utility model relates to the field of fixed bed technology, and in particular to a catalyst fixed bed device for advanced oxidation of traditional Chinese medicine wastewater. Background Technology

[0002] A fixed-bed reactor is a reactor that is filled with granular solid catalysts or solid reactants to form a bed of a certain height. Gas or liquid materials flow through the gaps between the particles through the stationary fixed bed, while a heterogeneous reaction process is achieved. The characteristic of this type of reactor is that the solid particles filled in the equipment are fixed and do not move. The catalyst fixed-bed device for advanced oxidation of traditional Chinese medicine wastewater is a key piece of equipment for treating traditional Chinese medicine wastewater.

[0003] However, the wastewater from traditional Chinese medicine contains fixed impurities, while the catalyst in the fixed bed usually has a certain porous structure to increase the contact area with the wastewater. If the wastewater is directly put into the fixed bed for reaction, the solid impurities in the wastewater will enter and accumulate, which will block these pores, preventing the wastewater from fully contacting the catalyst and affecting the reaction efficiency. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixed-bed catalyst device for advanced oxidation of traditional Chinese medicine wastewater. Through the combination of structures such as push rods, springs, and cams, the filter screen can be shaken upwards, accelerating the separation of solid impurities and wastewater. This prevents solid impurities from entering the catalyst layer and clogging the pores of the catalyst, thereby improving reaction efficiency.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fixed-bed catalyst device for advanced oxidation of traditional Chinese medicine wastewater includes a fixed-bed body. A cover plate is installed at the upper end of the fixed-bed body, and a feed pipe is connected to the upper end of the cover plate. A discharge pipe is connected to the inner bottom of the fixed-bed body. A filter screen is installed inside the fixed-bed body. A partition plate is fixedly connected to the inner wall of the fixed-bed body, and an opening is formed in the partition plate. A catalyst layer is fixedly connected to the inner wall of the fixed-bed body. Fixed plates are fixedly connected to both inner walls of the fixed-bed body. Two abutment rods are fixedly connected to the lower end of the filter screen, and the lower ends of the two abutment rods penetrate the corresponding fixed plates. Springs are fitted onto the outer walls of the two abutment rods, and the two ends of the two springs are elastically connected to the lower end of the filter screen and the upper end of the corresponding fixed plate, respectively. A rotating shaft is rotatably connected between the two inner walls of the fixed-bed body. Two cams are fixedly connected to the outer wall of the rotating shaft, and the two cams cooperate with the corresponding abutment rods. A sealing door is provided on one side wall of the fixed-bed body.

[0007] Preferably, the lower end of the fixed bed body is fixedly connected to two support legs, and the lower ends of the two support legs are provided with anti-slip texture.

[0008] Preferably, a motor is installed on the outer wall of the fixed bed body, and the end of the output shaft of the motor extends into the interior of the fixed bed body and is fixedly connected to one end of the rotating shaft.

[0009] Preferably, the lower end of the partition is rotatably connected to a rotating disk, and the outer wall of the rotating disk is fixedly connected to multiple rotating plates. Each rotating plate is hollow inside and communicates with the interior of the rotating disk. Each rotating plate has multiple liquid outlets at its inner bottom.

[0010] Preferably, a drive shaft is fixedly connected to the inner bottom of the rotating disk, and bevel gears are fixedly connected to both the drive shaft and the rotating shaft, with the two bevel gears meshing.

[0011] Preferably, heating boxes are fixedly connected to both outer walls of the fixed bed body, and electric heating tubes are installed in both heating boxes.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The filter screen is set up with a push rod, spring and cam structure. The continuous rotation of the cam makes the filter screen shake up and down, thereby accelerating the separation of solid impurities and wastewater. In this way, the fixed impurities are separated out, which can prevent the fixed impurities from entering the catalyst layer and blocking the pores of the catalyst, thus preventing the wastewater from fully contacting the catalyst and improving the reaction efficiency.

[0014] 2. The system is equipped with a rotating disc, rotating plates, and bevel gears. The rotating disc drives multiple rotating plates to rotate, which increases the spray range of wastewater under the action of centrifugal force. This allows the wastewater to enter the catalyst layer evenly and react fully with the catalyst. In addition, a heating box and electric heating tubes are installed to heat the fixed bed body, further improving the reaction efficiency. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-Figure 5 A fixed bed catalyst device for advanced oxidation of traditional Chinese medicine wastewater includes a fixed bed body 1. Two support legs 2 are fixedly connected to the lower end of the fixed bed body 1, and both support legs 2 have anti-slip textures at their lower ends. A cover plate 3 is installed at the upper end of the fixed bed body 1, and a feed pipe 4 is connected to the upper end of the cover plate 3. A discharge pipe 5 is connected to the inner bottom of the fixed bed body 1, and a solenoid valve is installed inside the discharge pipe 5. A filter screen 6 is installed inside the fixed bed body 1, and solid impurities that cannot pass through the mesh of the filter screen 6 will remain on the filter screen 6. A partition plate 7 is fixedly connected to the inner wall of the fixed bed body 1, and an opening is provided in the partition plate 7. A catalyst layer 8 is fixedly connected to the inner wall of the fixed bed body 1. Fixed plates 9 are fixedly connected to the inner walls on both sides of the fixed bed body 1. Two abutment rods 10 are fixedly connected to the lower end of the filter screen 6, and the lower ends of the two abutment rods 10 are both arc-shaped surfaces, with the lower ends of the two abutment rods 10 penetrating the corresponding fixed plates 9.

[0023] The outer walls of the two abutment rods 10 are fitted with springs 11. The two ends of the two springs 11 are elastically connected to the lower end of the filter screen 6 and the upper end of the corresponding fixing plate 9, respectively. The inner walls of the two sides of the fixed bed body 1 are rotatably connected to a rotating shaft 12. The outer wall of the rotating shaft 12 is fixedly connected to two cams 13. The two cams 13 are engaged with the corresponding abutment rods 10. Through the continuous rotation of the two cams 13, the lower ends of the two abutment rods 10 continuously abut against the corresponding cams 13 and move up and down with the rotation of the corresponding cams 13, thereby causing the filter screen 6 to shake up and down. This can accelerate the separation of solid impurities and wastewater and prevent solid impurities from entering the catalyst layer 8 and blocking the pores of the catalyst, which would prevent the wastewater from fully contacting the catalyst. The outer wall of the fixed bed body 1 is equipped with a motor 14. The output shaft of the motor 14 extends into the interior of the fixed bed body 1 and is fixedly connected to one end of the rotating shaft 12.

[0024] The lower end of the partition 7 is rotatably connected to a rotating disk 15. Multiple rotating plates 16 are fixedly connected to the outer wall of the rotating disk 15. Each rotating plate 16 is hollow and communicates with the interior of the rotating disk 15. Multiple liquid outlets 17 are opened at the bottom of each rotating plate 16. The rotating disk 15 cooperates with the outlets, allowing filtered wastewater to enter the rotating disk 15 through the outlets, then into the multiple rotating plates 16, and finally spray out through the multiple liquid outlets 17 into the catalyst layer 8 for reaction. The rotating disk 15 rotates the multiple rotating plates 16, increasing the spray range of the wastewater under centrifugal force, thereby... Wastewater can uniformly enter the catalyst layer 8 and react fully with the catalyst. A drive shaft 18 is fixedly connected to the inner bottom of the rotating disk 15. Both the drive shaft 18 and the rotating shaft 12 are fixedly connected to bevel gears 19, which mesh. Heating boxes 20 are fixedly connected to both outer walls of the fixed bed body 1. Electric heating tubes 21 are installed in both heating boxes 20. The fixed bed body 1 is heated by the electric heating tubes 21, thereby accelerating the reaction rate and improving the treatment efficiency. A sealing door 22 is provided on one side wall of the fixed bed body 1. The sealing door 22 can be opened to collect and treat solid impurities on the filter screen 6.

[0025] In this invention, when in use, traditional Chinese medicine wastewater is added into the fixed bed body 1 through the feed pipe 4. The motor 14 can be started, causing the rotating shaft 12 to rotate, which in turn causes the two cams 13 to rotate. During the rotation, when the two cams 13 contact the corresponding push rods 10, they push the two push rods 10 and move the filter screen 6 upward. When the two cams 13 separate from the corresponding push rods 10, under the elastic action of the two springs 11, the two push rods 10 move the filter screen 6 downward. In this way, the two push rods 10 continuously abut against the corresponding cams 13 and move up and down with the rotation of the corresponding cams 13, which causes the filter screen 6 to shake up and down, accelerating the separation of solid impurities and wastewater. This prevents solid impurities from entering the catalyst layer 8 and blocking the pores of the catalyst, thus preventing the wastewater from fully contacting the catalyst.

[0026] The filtered wastewater enters the rotating disk 15 through the inlet, then enters multiple rotating plates 16, and finally sprays out through multiple outlets 17 into the catalyst layer 8 for reaction. During the above process, after the motor 14 is started, it drives the drive shaft 18 to rotate through the transmission action of two bevel gears 19, which in turn causes the rotating disk 15 to rotate with multiple rotating plates 16. Under the action of centrifugal force, the spray range is increased, so that the wastewater can enter the catalyst layer 8 evenly and react fully with the catalyst. In addition, during this process, two electric heating tubes 21 can be activated to heat the fixed bed body 1, further improving the reaction efficiency.

[0027] 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.
