DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

The side of the gear 209 meshes with the side of the gear block 211, the number of the rotating shaft 207 is set to be several, and is arranged in a circumferential array at the bottom of the turntable 205, and the bottom of the rotating rod 204 is fixedly connected with a scraper 210. The number of the stirring blades 208 is set to be several, and is arranged in a circumferential array on the circumferential surface of the rotating shaft 207, and the number of the gears 209 is set to be several, and is arranged in a circumferential array at the bottom of the turntable 205. The top of the support frame 101 is provided with a filter device 3, and the filter device 3 includes a belt 301, which is rotatably connected to the circumferential surface of the rotating rod 204, and the end of the belt 301 away from the rotating rod 204 is rotatably connected to the rotating rod 302, and the circumferential surface of the rotating rod 302 is fixedly connected to the bevel gear 304, and the side of the analyzer body 102 is penetrated by a rotating shaft 306, one end of the rotating shaft 306 is fixedly connected to a bevel gear 305, and the other end of the rotating shaft 306 is fixedly connected to an eccentric wheel 307. A fixing plate 303 is fixedly connected to the side of the analyzer body 102 , the circumferential surface of the rotating rod 302 penetrates the top of the fixing plate 303 , and the side of the bevel gear 305 meshes with the side of the helical gear 304 .The inner wall of the analyzer body 102 is fixedly connected with a positioning plate 309, the top of the positioning plate 309 is fixedly connected with a spring 310, and the end of the spring 310 away from the positioning plate 309 is fixedly connected with a filter plate 311. Since the rotating rod 204 drives the rotating disk 205, the spiral blade 206 and the scraper 210 to rotate, the water sample in the mixing barrel 202 can be effectively mixed and stirred, which ensures that various chemical substances and particulates in the water sample are evenly distributed, which is beneficial to the accuracy and reliability of subsequent water quality analysis. The design of the scraper 210 can be regularly cleaned and stirred. The eccentric wheel 307 is designed to move the water sample at the bottom of the stirring barrel 202 to prevent impurities from accumulating at the bottom. The design of the eccentric wheel 307 enables the filter disc 311 to move up and down quickly under the squeezing of the eccentric wheel 307, thereby accelerating the filtration process. By continuously squeezing the filter disc 311, the water sample is effectively pushed through the filter disc 311, thereby improving the filtration speed and efficiency.

Since the gear 209 and the tooth block 211 are meshed with each other, when the turntable 205 drives the rotating shaft 207 to revolve, the gear 209 will drive the rotating shaft 207 to rotate, thereby achieving the effect of uniformly stirring the water inside the mixing barrel 202. The rotation of the rotating rod 204 drives the scraper 210 to rotate, and the scraper 210 can stir the water at the bottom of the mixing barrel 202 to prevent impurities from accumulating.

[0036] The belt 301 is driven to rotate by the rotation of the rotating rod 204 during the above stirring process, and the rotating rod 302 is driven to rotate by the rotation of the belt 301, and the bevel gear 304 is driven to rotate by the rotation of the rotating rod 302, and the bevel gear 304 is driven to rotate by the rotation of the bevel gear 305, and the rotating shaft 306 is driven to rotate by the rotation of the bevel gear 305, and the eccentric wheel 307 is driven to rotate by the rotation of the rotating shaft 306. When the raised side of the eccentric wheel 307 squeezes the filter disc 311, the filter disc 311 will move upward, and when the raised side of the eccentric wheel 307 is separated from the filter disc 311, the filter disc 311 is reset by the elastic force of the spring 310, and the eccentric wheel 307 will continue to squeeze the filter disc 311. The water in the mixing barrel 202 enters the top of the filter disc 311 after being evenly stirred, and the filtering speed is accelerated by continuously squeezing the filter disc 311
