Description

Technical Field

[0001] This utility model relates to the field of catalyst development technology, and in particular to an analyzer for developing BOD series catalysts. Background Technology

[0002] BOD series catalysts have wide applications in wastewater treatment and environmental monitoring.

[0003] The working principle of BOD series catalysts is mainly to accelerate the rate of biochemical reactions by reducing the activation energy required for the oxidation of organic matter. In BOD determination, the catalyst can accelerate the oxidation process of organic matter in water samples, enabling it to be decomposed by microorganisms in a short time, thus more accurately reflecting the biodegradability of the water sample.

[0004] In existing technologies, catalysts play a crucial role in the chemical industry, accelerating chemical reaction rates, improving production efficiency, and reducing energy consumption and costs. Therefore, developing efficient, stable, and environmentally friendly catalysts is of great significance for promoting the development of the chemical industry. Most existing analyzers can only analyze single catalysts, while catalyst development requires simultaneous analysis of multiple batches of catalysts. Therefore, existing analyzers that only analyze single catalysts significantly impact the efficiency of catalyst development. Utility Model Content

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 The present invention discloses an analyzer for developing BOD series catalysts, including a reaction liquid storage tank 1 and a catalytic reaction tank 2. The top side wall of the reaction liquid storage tank 1 is provided with a connecting pipe 3 that communicates with the catalytic reaction tank 2. The catalytic reaction tank 2 is provided with a support cylinder 4. The support cylinder 4 is provided with several separation chambers 5. Catalytic tubes 6 are inserted into the separation chambers 5. A reaction sensor is provided at the bottom of the catalytic tubes 6. The top of the catalytic tubes 6 are connected to a mounting plate 7. A hexagonal shaft 8 is provided at the center of the mounting plate 7. A flow splitting structure 9 is provided at the top of the mounting plate 7. A driving structure 10 is provided at the top of the catalytic reaction tank 2.

[0028] The flow divider structure 9 includes a flow divider cavity 91, a connecting plate 92 is rotatably provided at the bottom end of the flow divider cavity 91, a connector 93 corresponding to the catalyst tube 6 is provided at the bottom end of the connector 92, and a connecting hose 94 is provided at the position corresponding to the connecting tube 3 in the flow divider cavity 91.

[0029] In this embodiment, during use, the liquid to be catalyzed is introduced into the interior of the reaction liquid storage tank 1, and then different catalysts are placed into different catalyst tubes 6. The catalytic reaction tank 2 and the reaction liquid storage tank 1 are connected by the connecting pipe 3. After the catalyst is placed, the catalyst tube 6 is inserted into the interior of the separation chamber 5. The diversion structure 9 is then inserted into the top of the mounting plate 7. After the diversion structure 9 is inserted into the top of the mounting plate 7, the connecting hose 94 of the diversion structure 9 corresponds to the connecting pipe 3, so that the diversion chamber 91 and the connecting pipe 3 are connected to each other, and the insertion pipe 93 is inserted into the upper port of the catalyst tube 6.

[0030] At this time, the liquid inside the reaction liquid storage tank 1 is introduced into the inside of the diversion structure 9. After being diverted by the diversion mechanism, the liquid to be catalyzed enters the inside of different catalytic tubes 6, so that the reaction liquid reacts with the participation of different catalysts. After a period of reaction, the reaction effect is measured by the reaction sensor built into the catalytic tube 6, thereby achieving the goal of simultaneously measuring multiple batches of catalysts to improve the efficiency of catalyst development. The drive structure 10 drives the hexagonal shaft 8 to rotate, so that the catalytic tube 6 rotates to improve the reaction efficiency between the catalyst and the liquid, reduce the reaction time of the catalyst, and improve the efficiency of catalyst development.

[0031] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the drive structure 10 includes a drive motor 101, a motor bracket 102 is provided at the bottom of the drive motor 101, and a hexagonal insert 103 is rotatably provided at the bottom of the motor bracket 102. The hexagonal insert 103 is coaxially arranged with the motor shaft of the drive motor 101 and is fixedly connected.

[0032] In this embodiment, the drive motor 101 is fixedly installed on the top of the catalytic reaction tank 2 by the motor bracket 102, and the motor bracket 102 and the catalytic reaction tank 2 are fixedly connected by a quick-release clamp. The motor shaft of the drive motor 101 is connected to the hexagonal shaft 8 by the hexagonal tube 103, so that the hexagonal shaft 8 can be rotated by the drive motor 101.

[0033] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the reaction liquid storage tank 1 is equipped with a closed piston 11 inside, a closed plate 12 is threadedly connected to the top of the reaction liquid storage tank 1, and a pushing structure 13 is provided at the bottom of the reaction liquid storage tank 1.

[0034] In this embodiment, by setting the sealing plate 12, when the liquid to be catalyzed is added into the interior of the reaction liquid storage tank 1, the sealing plate 12 is used to seal the upper opening of the reaction liquid storage tank 1, and the sealing piston 11 is pushed upward by the pushing structure 13, so that the liquid moves upward, so that the reaction liquid can enter the interior of the catalytic reaction tank 2 through the connecting pipe 3.

[0035] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the pushing structure 13 includes a connecting bend 131. One end of the connecting bend 131 is fixedly connected to the bottom end of the reaction liquid storage tank 1 and communicates with the reaction liquid storage tank 1. A compressed air pump 132 is provided at the end of the connecting bend 131 away from the reaction liquid storage tank 1.

[0036] In this embodiment, outside air is compressed by the air compressor 132 and introduced into the bottom of the reaction liquid storage tank 1 through the connecting bend pipe 131, thereby pushing the closed piston 11 to move upward by the air pressure.

[0037] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the bottom end of the closed piston 11 is provided with a cross-shaped guide groove 111, and the bottom wall edge of the closed piston 11 is set at an angle.

[0038] In this embodiment, the cross-shaped guide groove 111 allows air to be evenly distributed at the bottom of the closed piston 11, thereby improving the stability of the closed piston 11 when it moves upward.

[0039] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, a hexagonal insertion hole 41 that slides with the hexagonal shaft 8 is provided at the center of the support cylinder 4, and several bearings 42 are embedded in the outer wall of the support cylinder 4 for rotating connection between the support cylinder 4 and the catalytic reaction tank 2.

[0040] In this embodiment, the hexagonal socket 41 facilitates the positioning of the hexagonal shaft 8, and the bearing 42 enables the support cylinder 4 to be rotatably connected to the catalytic reaction tank 2, making the support cylinder 4 rotate more smoothly.

[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
