[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] In existing technologies, unreacted raw material particles often remain within the sodium bromate solution during filtration, affecting the purity of the final solution. Furthermore, filtration can easily clog the filter, impacting production quality and efficiency. Please refer to [the relevant documentation / reference]. Figures 1-5 The embodiment provides an impurity adsorption and filtration device for sodium bromate production, which can effectively improve the solubility of raw materials in the solution, thereby reducing the impact of undissolved raw materials on subsequent filtration and adsorption. The impurity adsorption and filtration device for sodium bromate production includes a filter box 1. Conveying and pressurizing devices are installed on the left and right sides and the front of the filter box 1. A mixing device is installed at the left end inside the filter box 1, and a filtration and adsorption device is installed at the right end inside the filter box 1.

[0027] The mixing device includes a stirring structure and a heating structure, with the heating structure installed inside and at the top of the stirring structure. The stirring structure includes an asynchronous motor 201, with a transmission component 202 connected to the output end of the asynchronous motor 201. A stirring shaft 203 is installed inside the transmission component 202, a stirring rod 204 is installed in the middle of the outer surface of the stirring shaft 203, and a scraper 205 is installed at the bottom end of the stirring shaft 203. The heating structure includes a heating tube 206, with a connector 207 installed at the top end of the heating tube 206, and a wire 208 connected to the middle of the top surface of the connector 207.

[0028] The asynchronous motor 201 is detachably installed on the top surface of the filter box 1. The outer surface of the stirring shaft 203 is installed in the installation hole on the top surface of the filter box 1 through a sealed bearing near the top. The bottom surface of the scraper 205 is slidably connected to the bottom surface inside the filter box 1. The bottom surface of the connector 207 is rotatably connected to the top of the stirring shaft 203.

[0029] By setting up a mixing device, the asynchronous motor 201 is started to drive the transmission component 202 and the stirring shaft 203 for transmission. The stirring rod 204, scraper 205 and heating tube 206 are used for heating and stirring, which helps to further dissolve the unblended raw material particles.

[0030] When adsorbing and filtering the sodium bromate solution, the asynchronous motor 201 is started to drive the transmission component 202. The output end of the asynchronous motor 201 drives the worm to rotate. The outer surface of the worm meshes with the outer surface of the worm wheel, thereby driving the stirring shaft 203 to rotate. When the stirring shaft 203 rotates, it drives the stirring rod 204 and the scraper 205 to rotate, thereby mixing and stirring the sodium bromate solution to ensure the dissolution rate of the raw materials. At the same time, the heating tube 206 is started by the wire 208 and the connector 207 to heat the solution, keeping the stirred sodium bromate solution within a certain temperature range, which facilitates the further dissolution of undissolved raw materials. Example

[0031] Based on Implementation 1, existing technologies still suffer from low filtration efficiency and difficulty in cleaning the filter structure. Please refer to... Figures 1-5This embodiment provides an impurity adsorption and filtration device for sodium bromate production, which effectively solves the problems of low filtration efficiency and inconvenience in cleaning and replacing the filter structure. The impurity adsorption and filtration device for sodium bromate production includes a conveying and pressurizing device comprising an air pump 101. An air inlet pipe 102 is connected to the input end of the air pump 101, and an air delivery pipe 103 is connected to the output end of the air pump 101. A liquid inlet pipe 104 is located on the left rear side of the air pump 101, and a liquid outlet pipe 105 is located on the right rear side of the air pump 101. The air pump 101 is installed on the front of the filter box 1 near the left end. The end of the air delivery pipe 103 away from the air pump 101 is internally connected to the front of the filter box 1 near the left end through a connection hole. The liquid inlet pipe 104 is installed on the left middle part of the filter box 1 near the top, and the liquid outlet pipe 105 is installed on the right middle part of the filter box 1 near the bottom.

[0032] The filtration and adsorption device includes an electric push rod 301, the output end of which is connected to a lifting plate 302. A slot 303 is installed near both ends on the bottom center of the lifting plate 302. A locking block 304 is connected to the bottom center of the slot 303, and a filter plate 305 is connected to the bottom surface of the locking block 304. The electric push rod 301 is detachably installed on the top surface of the filter box 1. The top of the outer surface of the locking block 304 engages with a convex groove in the bottom center of the slot 303. The outer surface of the filter plate 305 is slidably connected to the inner wall of a rectangular hole near the right end of the top surface of the filter box 1.

[0033] By activating the filtration and adsorption device, the electric push rod 301 is activated to lift the filter plate 305 using the lifting plate 302, which facilitates timely disassembly and cleaning of the filter plate 305, thereby ensuring the filtration and adsorption effect.

[0034] When filtering sodium bromate solution, the solution is transported into the filter box 1 through the inlet pipe 104. Then, the air pump 101 is started to draw nitrogen through the air inlet pipe 102 and deliver the nitrogen into the filter box 1 through the air delivery pipe 103, thereby pressurizing the left end of the filter box 1 and improving the filtration efficiency of the filter structure. When the filter plate 305 needs to be disassembled, cleaned and replaced after filtration, the electric push rod 301 is started to drive the lifting plate 302 to rise and fall. The locking of the slot 303 and the locking block 304 drives the filter plate 305 to rise and fall. At the same time, the locking of the locking block 304 and the slot 303 facilitates the replacement and cleaning of the filter plate 305, ensuring the filtration effect.
