[0023] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] During the chemical analysis process, filtration is a common basic operation. Currently, during filtration in a laboratory, it is generally carried out on a funnel rack, and waste liquid is collected using a waste liquid cup during filtration. Moreover, each funnel corresponds to a waste liquid cup. This structure can meet the requirements for the chemical analysis of a small number of samples, and the waste liquid cup can accommodate all the waste liquid. However, during some gravimetric analysis filtrations, due to the large number of washings, the waste liquid cup cannot accommodate all the waste liquid, and the waste liquid cup needs to be replaced multiple times, resulting in cumbersome operations, time-consuming, and laborious. At the same time, when replacing the waste liquid cup, there will also be an overflow of waste liquid, polluting the workbench surface. If the waste liquid is corrosive, it will also cause harm to the operator.

[0025] The Chinese patent with the publication number CN218553293U discloses a chemical analysis filtration device, which includes a filtration rack and a filtrate tank. The filtration rack successively has from top to bottom: a top plate, a partition plate and a grid plate. A filtrate tank is arranged below the filtration rack. The filtration rack can accommodate multiple filtration funnels, and the filtrate of each funnel can be directly discharged into the filtrate tank and centrally collected by the filtrate tank. On the one hand, this structure can simultaneously conduct chemical analysis tests on multiple samples. On the other hand, the filtrate tank has a relatively large volume, so when performing some gravimetric analysis filtrations, there is no need to consider the situation of replacing the waste liquid cup. Moreover, the above device is equipped with a support structure that can adjust the positions of the partition plate and the grid plate on the filtration rack, and can collect useful filtrate during chemical analysis through a variety of containers, greatly increasing the compatibility with funnels and filtrate collection containers. As can be seen from the above, although the above chemical analysis filtration device can avoid the problem of cumbersome operation and time-consuming and laborious work caused by the need to replace the waste liquid cup multiple times because the waste liquid cup cannot accommodate all the waste liquid due to a large number of washing times during gravimetric analysis filtration, it cannot detect and analyze the components of the filtered impurities.

[0026] To solve the above problems, with reference to Figures 1 to 5 as shown, the present utility model provides an analysis filtration device, which includes: a filtration assembly 10, including a first box body 11 and a filtration structure, the filtration structure is installed in the inner cavity of the first box body 11 and is located at the discharge end of the first box body 11, and a feed port communicating with the inner cavity of the first box body 11 is arranged on the first box body 11; an analysis assembly 20, including a second box body 21 and an analysis and detection unit, the second box body 21 has a receiving cavity 211, the receiving cavity 211 communicates with the discharge end of the first box body 11, the analysis and detection unit is installed in the receiving cavity 211 and is located at the feed end of the second box body 21, the analysis and detection unit includes a spectral emitter 221, a spectral receiver 222 and a reflection grating 223, the spectral receiver 222 and the spectral emitter 221 are located on the same side, the reflection grating 223 is arranged opposite to the spectral emitter 221, the reflection grating 223 is located within the beam coverage area emitted by the spectral emitter 221, and the spectral receiver 222 is located within the beam coverage area reflected by the reflection grating 223.

[0027] In this embodiment, the material and the reaction solution respectively enter the inner cavity of the first box body 11 through the feed ports. The two react in the inner cavity of the first box body 11 to generate precipitate impurities. The filtering structure is located at the discharge end of the first box body 11. The precipitate impurities generated by the reaction of the material and the reaction solution are preliminarily separated by the filtering structure. Impurity particles with larger particles can be intercepted in the first box body, while impurity particles with smaller particles can enter the accommodation cavity 211 through the discharge end of the first box body 11 along with the solution. Then, the light beam emitted by the spectral emitter 221 passes through the impurities and shoots towards the reflection grating 223. After the light beam shoots towards the reflection grating 223, it will be reflected. The reflected light beam is received by the spectral receiver 222. The wavelength and intensity of the light are detected and recorded by the spectral receiver 222, so as to detect the chemical composition of the impurities.

[0028] It should be noted that the material refers to the sample that needs to be analyzed and tested, which can be solid particles, powders or liquids. For example, in the process of water treatment, the material can be suspended solid particles. The reaction solution refers to the liquid that reacts chemically with the material and usually contains chemical reagents for precipitation reactions. For example, when detecting heavy metals in a water sample, the reaction solution can be a sodium hydroxide solution for generating precipitates of heavy metal ions.

[0029] In one embodiment, the filtering structure is a filter screen. By controlling the aperture size of the mesh holes of the filter screen, the separation effect of intercepting impurity particles with larger particles in the first box body 11 and allowing impurity particles with smaller particles to pass through can be achieved.

[0030] Refer to Figures 1 to 5 As shown in the figure, in one embodiment of the present utility model, the analysis and filtering device further includes a weighing assembly. The weighing assembly includes a feed pipe 30 and a weighing structure 40. The weighing structure 40 is installed in the feed pipe 30. The discharge end of the feed pipe 30 is communicated with the feed port. The weighing structure 40 includes a supporting member 41 and a weighing sensor 42 arranged at the bottom of the supporting member 41.

[0031] In this embodiment, in the initial state, the bottom of the supporting member 41 is not communicated with the discharge end of the feed pipe 30. The material enters the feed pipe 30 from the feed end of the feed pipe 30 and then falls on the supporting member 41. The material is weighed by the weighing sensor 42 at the bottom of the supporting member 41. When the material reaches the preset weight, the bottom of the supporting member 41 is communicated with the discharge end of the feed pipe 30. At this time, the material enters the inner cavity of the first box body 11 through the discharge end of the feed pipe 30 and the feed port. Through the above settings, the weight of the added material can be effectively measured, and the addition of a preset weight of material into the inner cavity of the first box body 11 can be realized. In this way, the addition amount of the reaction solution can be adjusted and controlled according to the added amount of the material, and the waste of the reaction solution can be avoided.

Through the above settings, the installation stability of the weighing structure 40 can be ensured, ensuring that the load cell 42 can accurately measure the weight of the material. At the same time, the above settings not only enable the load cell 42 to be reliably installed in the feed pipe 30, but also ensure that the support member 41 can remain stable during the weighing process, thereby improving the weighing accuracy.
