Description

TECHNICAL FIELD

[0001] The utility model relates to detection field especially, it relates to a filter container and detection appearance of smooth drainage. BACKGROUND

[0002] At present, the general method for determining the content of free silicon dioxide in dust is to use the pyrophosphoric acid method. A crucial link in this process is to place the sample in a filtering device and repeatedly add water until the filtrate no longer shows acidity. The detection equipment used in this process includes a funnel, a beaker and other basic tools. Among them, the funnel is used to support and fix the filter paper. When in use, the filter paper is tightly attached to the inner wall of the funnel without leaving enough space for the liquid to flow smoothly. Therefore, the liquid can only slowly penetrate the pores of the filter paper by relying on gravity, and only a limited flow area is formed at the bottom of the funnel, which directly leads to slow filtration rate and low efficiency. In addition, hot distilled water must be continuously supplied for flushing during the filtration to prevent the pyrophosphoric acid from forming a gelatinous substance that is difficult to filter when the temperature drops below 50℃, thus making the entire detection process time-consuming and labor-intensive. In summary, the existing filtering device for silicon dioxide detection needs to be optimized and upgraded. SUMMARY

[0003] The utility model aims at solving the problem of low filtration efficiency and time-consuming and labor-intensive when assisting in flushing and filtering the sample through the existing funnel, and provides a filtering container with smooth drainage.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] The filtering container with smooth drainage includes a filter cup body, the filter cup body is provided with a filter cavity with an open upper end, the bottom of the filter cavity is provided with a liquid outlet hole, a flow guide channel is arranged on the inner wall of the filter cavity, and the bottom of the flow guide channel is connected with the liquid outlet hole to guide the liquid filtered by the filter paper from the flow guide channel to the liquid outlet hole.

[0006] Compared with the prior art, the filtering container of the utility model has a flow guide channel design. While retaining the function of supporting and fixing the filter paper of the filtering body, it can increase the flow space of the filter cup body, so that the liquid filtered by the filter paper can flow along the inner wall of the filter cavity to the liquid outlet hole. Moreover, the flow guide channel guides the liquid, further improves the filtration rate and shortens the filtration time. When applied to the filtering device for silicon dioxide detection, it can significantly improve the filtration efficiency, save time and labor cost, and reduce the detection difficulty.

[0007] As a preferred solution of the flow guide channel, the flow guide channel comprises a first flow guide channel arranged in a spiral shape. This solution enables the flow guide channel to form a longer path on the limited area of the inner wall of the filter cavity, thereby increasing the flow space. In the limited space, the spiral flow guide channel can guide the fluid to flow in a spiral path, which can reduce the speed and vortex of the fluid and reduce the resistance of the fluid flow. Alternatively, the flow guide channel comprises a second flow guide channel arranged longitudinally, and the first flow guide channel and the second flow guide channel are staggered. In this solution, the second flow guide channel also has a flow guiding effect, which cooperates with the first flow guide channel to further increase the flow space and improve the filtering efficiency. By arranging such a flow guide channel, the drainage speed of the filter container can be increased by 5 times.

[0008] As another preferred solution of the flow guide channel, the flow guide channel comprises a first flow guide channel arranged transversely and a second flow guide channel arranged longitudinally, which are staggered to form a mesh structure, and the bottom of the second flow guide channel is connected to the liquid outlet hole. In this solution, the first flow guide channel and the second flow guide channel are staggered to form a mesh or warp and weft line-shaped flow guide channel, which is different from the above-mentioned solution in that the first flow guide channel is arranged transversely, and the flow ultimately needs to pass through the second flow guide channel to be guided to the liquid outlet hole.

[0009] Further, the flow guide channel extends from the upper part of the inner wall of the filter cavity to the liquid outlet hole. This ensures that the liquid is guided by the flow guide channel throughout the filtering process, thereby avoiding the disorderly flow and accumulation of the liquid in the filter cavity.

[0010] Further, the filter cavity is designed in a circular arc shape that gradually narrows from top to bottom. In this solution, the shape of the filter cavity not only resembles the shape of a funnel and matches the shape of the folded filter paper, but also meets the filtering requirements and enables maximum area loading.

[0011] Further, the cross section of the flow guide channel is in a groove shape.

[0012] Further, the overall shape of the filter cup body is in a column shape. This solution can improve the structural stability of the filter container and enable stable placement. Alternatively, the outer part of the filter cup body is in a waist shape, which facilitates the user's grip while maintaining the structural stability of the filter container.

[0013] Further, the filter cup body is made of a plastic material that is resistant to high temperature and corrosion; or the filter cup is made of glass.

[0014] Further, the outer wall of the filter cup body is provided with a mounting structure for cooperation with a silicon dioxide detection device.

[0015] Further, the mounting structure comprises a connecting protrusion arranged at the lower part of the outer side wall of the filter cup body, and a recess is formed between the connecting protrusion and the side of the filter cup body.

[0016] The utility model discloses a further invention purpose at providing a kind of detector, it includes organism and the filter container of above-mentioned scheme, filter container is located on organism. Compared with prior art, the detector of the utility model because of the filter container of above-mentioned scheme is applied, therefore, it has all the advantages of above-mentioned scheme. It can significantly improve efficiency, save time and manpower cost, reduce test difficulty. BRIEF DESCRIPTION OF DRAWINGS

[0034] As a preferred scheme of the flow guide channel 4, the flow guide channel 4 comprises a first flow guide channel 41 arranged in a spiral shape. This scheme makes the flow guide channel 4 form a longer path on the limited area of the inner wall of the filter cavity 2, thereby increasing the flow space. In the limited space, the spiral flow guide channel can guide the fluid to flow in a spiral path, and this flow form can reduce the speed and vortex of the fluid and reduce the resistance of the fluid flow. Alternatively, the flow guide channel 4 comprises a second flow guide channel 41 arranged longitudinally, and the first flow guide channel 41 and the second flow guide channel 41 are staggered with each other. In this scheme, the second flow guide channel 41 also has a flow guide effect, and cooperates with the first flow guide channel 41 to further increase the flow space and improve the filtering efficiency.

[0035] As another preferred scheme of the flow guide channel 4 (not shown in the figure), the flow guide channel 4 comprises a first flow guide channel 41 arranged transversely and a second flow guide channel 41 arranged longitudinally, and the two are staggered to form a mesh structure, and the bottom of the second flow guide channel 41 is connected with the liquid outlet hole 3. In this scheme, the first flow guide channel 41 and the second flow guide channel 41 are staggered to form a mesh or warp and weft line-shaped distributed flow guide channel 4, and the difference from the above scheme is that, since the first flow guide channel 41 is arranged transversely, the flow finally needs to pass through the second flow guide channel 41 to be guided to the liquid outlet hole 3. The above first flow guide channel 41 is provided with one, and the second flow guide channel 41 is uniformly provided with 2-4.

[0036] To ensure that the liquid can be guided by the flow guide channel 4 during the whole filtering process, avoid the disorder flow and accumulation of the liquid in the filter cavity 2, the flow guide channel 4 extends from the upper portion of the inner wall of the filter cavity 2 to the liquid outlet hole 3.

[0037] To increase the capacity of the filter cavity 2 while ensuring the supporting and fixing functions, the filter cavity 2 is designed in a circular arc shape which gradually narrows from top to bottom.

[0038] To avoid the shape deformation of the filter paper caused by the flow guide channel 4, the cross section of the flow guide channel 4 is in a groove shape.
