Description

Technical Field

[0001] This utility model relates to the field of chemical analysis and detection technology, and in particular to a filtration auxiliary device for chemical analysis and detection. Background Technology

[0002] Chemical analysis primarily involves detecting the composition of substances and determining their concentrations. In chemical analysis experiments, the solution being tested needs to be filtered to remove impurities to ensure the accuracy of the results.

[0003] Publication number CN218653267U discloses a filtration auxiliary device for chemical analysis and detection. However, in the implementation of this solution, if the solution is filtered through a traditional filter screen, impurities adhere to the surface of the filter screen and are easily clogged, making the device unusable and affecting the filtration efficiency of the device. Therefore, a filtration auxiliary device for chemical analysis and detection is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a filtration auxiliary device for chemical analysis and detection that can solve the problems in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This chemical analysis and detection filtration auxiliary device introduces solution into the device through a feed pipe. A baffle blocks the solution, causing the liquid level to rise as more solution is added. Impurities settle at the bottom of the liquid due to their own weight, preventing them from clogging the filter holes. The relatively clean solution is filtered through the filter holes at the top of the filter box. After the solution has been completely poured into the feed pipe, the baffle is moved upwards, allowing the solution that could not pass through the filter box to enter the filter plate position. Impurities at the first support plate position move less, and the remaining solution is filtered through the filter plate, thus preventing impurities from clogging the filter screen and affecting the use and filtration efficiency of the device.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a filtration auxiliary device for chemical analysis and detection, including a housing 2. A first support plate 15, dividing the internal space of the housing 2, is fixedly connected inside the housing 2. A limiting strip 19, which limits the position of a baffle 18, is fixedly connected to the upper surface of the first support plate 15. A baffle 18, which separates the solution, is slidably connected inside the limiting strip 19. A second limiting block 17, which limits the position of a threaded rod 5, is fixedly connected to the upper surface of the baffle 18. A threaded rod 5, which drives the baffle 18 upward, is rotatably connected inside the second limiting block 17. A first... The first limiting block 3 is threadedly connected to the outer surface of the threaded rod 5. The upper surface of the first support plate 15 is fixedly connected to a filter box 14 for filtering the solution. The back of the first support plate 15 is fixedly connected to a filter plate 16 for filtering the remaining solution. The inside of the box 2 is fixedly connected to a third support plate 25 that divides the internal space of the box 2. The inside of the third support plate 25 is fixedly connected to a feed pipe 10 for guiding the solution. The top end of the feed pipe 10 is fixedly connected to the lower surface of the first support plate 15. The outer surface of the feed pipe 10 is provided with slots 23 to facilitate the solution passing through the filter plate 16 into the elastic hose 22.

[0026] During operation, rotating the handle 4 causes the threaded rod 5 to rotate with the first limiting block 3, moving the baffle 18 downwards until it contacts the first support plate 15. Opening the cover 6 allows the solution to be filtered to be introduced into the upper surface of the first support plate 15 through the feed pipe 7. The solution slowly rises until it overflows the filter holes on the filter box 14. Impurities settle at the bottom due to their own weight, preventing clogging of the filter holes. The relatively clean solution at the top passes through the filter box 14 and enters the lower device through the feed pipe 10, completing the filtration process. When no more solution is injected into the feed pipe 7, reversing the handle 4 moves the baffle 18 upwards. At the position of the first support plate 15, impurities move less, and the solution passes through the filter plate 16, completing the static filtration of the remaining solution. The remaining solution flows into the lower device through the slot 23, preventing impurities from clogging the filter screen and affecting filtration efficiency.

[0027] A handle 4 is fixedly connected to the upper surface of the threaded rod 5 to facilitate rotation of the threaded rod 5.

[0028] During operation, the threaded rod 5 drives the baffle 18 to move upward.

[0029] The inside of the housing 2 is fixedly connected to the feed pipe 7 that guides the solution into the device, and the upper surface of the feed pipe 7 is provided with a cover 6 of the sealing device.

[0030] During operation, the solution is transported through the feed pipe 7.

[0031] The lower surface of the feed pipe 10 is fixedly connected to an elastic hose 22 for easy temporary material removal, and the bottom end of the elastic hose 22 is fixedly connected to an infusion head 20 for easy solution output.

[0032] During operation, the flexible tubing 22 facilitates the removal of the infusion head 20 to temporarily extract the solution.

[0033] The inside of the housing 2 is fixedly connected to a second support plate 21 that supports and limits the housing tube 24, and the inside of the second support plate 21 is fixedly connected to the housing tube 24 that supports the infusion head 20.

[0034] During operation, the tube 24 serves to support and limit the position of the infusion head 20.

[0035] A discharge pipe 9 is fixedly connected to the lower surface of the box 2, and a push rod 8 is fixedly connected to the front of the box 2.

[0036] During operation, the material solution is output through the discharge pipe 9.

[0037] The lower surface of the housing 2 is provided with casters 1 to facilitate the movement of the device, and the right side of the housing 2 is fixedly connected to a second fixing block 13 with a limiting first fixing block 12.

[0038] During operation, the casters 1 facilitate the movement of the device.

[0039] The lower surface of the second fixing block 13 is rotatably connected to the first fixing block 12 that connects to the box door 11, and the back of the first fixing block 12 is fixedly connected to the box door 11 that facilitates the sealing device.

[0040] During operation, the box door 11 facilitates the removal of the infusion head 20 for temporary material retrieval.

[0041] Working principle: The solution to be filtered is introduced into the device through the feed pipe 7. The baffle 18 is moved to fit tightly against the first support plate 15, preventing the solution from entering the filter plate 16. As the solution continues to enter the device, the liquid surface rises until it is level with the filter screen opening above the filter box 14. Impurities in the solution first settle at the bottom due to their own weight, without clogging the filter screen opening. The solution then passes through the filter screen opening above the filter box 14 to filter out the smaller amount of impurities. The filtered solution flows into the device below through the feed pipe 10. After the solution has been completely poured into the feed pipe 7, the handle 4 is turned, utilizing the space between the threaded rod 5 and the first limiting block 3. The threaded drive moves the baffle 18 upward, so that the baffle 18 is no longer blocking the remaining solution from entering the filter plate 16. The filter plate 16 filters the solution in the device that cannot be filtered by the filter box 14, and completes the static filtration of the remaining solution. The remaining solution flows into the device below through the slot 23, where the impurities settle by their own weight, avoiding the impurities from clogging the filter screen and affecting the filtration efficiency. When temporary material removal is required, the box door 11 is opened, and the infusion head 20 is taken out from inside the box tube 24 to complete the temporary material removal. Then, the infusion head 20 is placed inside the box tube 24. Magnetic material is provided at the contact position between the infusion head 20 and the box tube 24 to ensure airtightness.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
