Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a chemical solution filtration device. Background Technology

[0002] In chemical experiments, solutions need to be filtered. Currently, during filtration, a vacuum pump is used to create negative pressure inside the filter bottle. Atmospheric pressure forces the solution in the upper storage bottle down into the lower filter bottle, and the foreign matter is filtered out by the filter screen.

[0003] However, traditional filtration methods use air pressure to force the solution downwards. As the solution passes through the filter screen, foreign objects are left on the screen. As the solution flows, the number of pores on the filter screen decreases, leading to a decrease in filtration efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a chemical solution filtration device that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical solution filtration device, comprising a filtrate bottle, a storage bottle, and a filter screen. The storage bottle has an inlet at its upper end and is positioned above the filtrate bottle. The filter screen is positioned between the connecting ends of the storage bottle and the filtrate bottle. A connecting suction pipe is fixedly connected to the side wall of the filtrate bottle. A motor is fixedly connected to the upper end of the storage bottle. A rotating rod is fixedly connected to the output end of the motor. A stirring element is fixedly connected to the side wall of the rotating rod. A placement groove is provided at the lower end of the rotating rod. An auxiliary feeding element is provided inside the placement groove, and the auxiliary feeding element abuts against the upper end of the filter screen. A sealing element is provided at the edge of the connecting end between the storage bottle and the filtrate bottle.

[0006] Furthermore, the auxiliary unloading component includes: a guide rod, which is connected within the placement groove, with a support rod fixedly connected to the lower end of the guide rod, and the support rods are symmetrically arranged. A pressure roller is rotatably connected to one of the support rods, and a scraper is fixedly connected to the other support rod. The scraper has toothed grooves at both ends, and the number of toothed grooves is multiple. A spring is fixed within the placement groove, and the lower end of the spring is fixedly connected to the upper end of the guide rod.

[0007] Furthermore, the stirring component includes a stirring rod, which is fixedly disposed on the side wall of the rotating rod, and a stirring blade is fixedly connected to the end of the stirring rod, and the stirring rod is inclined downward.

[0008] Furthermore, the sealing element includes: a sealing sleeve, which is semi-circular and is fitted onto the edge of the liquid storage bottle and the filtrate bottle. A sealing ring is fixedly connected to the inner wall of the sealing sleeve, and a fixing handle is fixedly connected to the outer end of the sealing sleeve.

[0009] Furthermore, a baffle is fixedly connected to the inner wall of the filtrate bottle. The baffle is positioned above the suction pipe and is inclined downwards.

[0010] Furthermore, the outer connecting end of the extraction pipe is folded.

[0011] Compared to the aforementioned background technology, the chemical solution filtration equipment provided in this application includes filtration equipment with very mature technology today, and core components such as auxiliary feeding parts, stirring parts and sealing parts. Its principle relies on the rotation of the support rod driven by the guide rod, and the scraper and pressure roller working together to scoop up and press down foreign objects on the filter screen. Through round after round of operation, the permeability of the filter screen can be increased, thereby improving the penetration rate of the solution.

[0012] This invention provides a chemical solution filtration device. Compared with the prior art, it has the following advantages:

[0013] This chemical solution filtration equipment, by setting up a stirring component, an auxiliary feeding component, and a sealing component, uses the rotation of a guide rod to drive a support rod, which in turn drives a pressure roller and a scraper to rotate on the filter screen. The scraper scoops up foreign objects on the filter screen, and the pressure roller presses the scooped-up foreign objects downwards, thus improving the solution penetration efficiency of the filter screen.

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a chemical solution filtration device, including a filter bottle 1, a storage bottle 2, and a filter screen 4. The upper end of the storage bottle 2 is provided with an inlet 3, and the storage bottle 2 is placed above the filter bottle 1. The filter screen 4 is positioned between the connecting ends of the storage bottle 2 and the filter bottle 1. A connecting suction pipe 20 is fixedly connected to the side wall of the filter bottle 1. A motor 8 is fixedly connected to the upper end of the storage bottle 2, and a rotating rod 9 is fixedly connected to the output end of the motor 8. A stirring element is fixedly connected to the side wall of the rotating rod 9. A placement groove 12 is opened at the lower end of the rotating rod 9, and an auxiliary feeding element is provided inside the placement groove 12. The auxiliary feeding element abuts against the upper end of the filter screen 4. A sealing element is provided at the edge of the connecting end between the storage bottle 2 and the filter bottle 1. During chemical solution filtration, the storage bottle 2 is placed above the filter bottle 1. A filter screen 4 is placed between the storage bottle 2 and the filter bottle 1. After the solution is poured into the storage bottle 2, air is drawn through the suction pipe 20 on the side wall of the filter bottle 1 to create a negative pressure, thereby allowing the solution in the storage bottle 2 to enter the filter bottle 1. The solution is filtered through the filter screen 4. A motor 8 is placed at the top of the storage bottle 2, which drives the rotating rod 9 to rotate. The rotating rod 9 drives the stirring component to fully stir the solution. A placement groove 12 is provided at the lower end of the rotating rod 9, and an auxiliary feeding component is set in the placement groove 12. The auxiliary feeding component rotates with the rotation of the rotating rod 9, which can scrape and crush the impurities that have been filtered at the top of the filter screen 4, thereby increasing the filtration efficiency of the filter screen 4 and making the solution flow faster. When the storage bottle 2 and the filter bottle 1 are connected, they are sealed with a sealing component to prevent solution leakage.

[0023] like Figure 6As shown, the auxiliary unloading components include: a guide rod 14, which is connected within the placement groove 12. A support rod 15 is fixedly connected to the lower end of the guide rod 14, and the support rods 15 are symmetrically arranged. A pressure roller 16 is rotatably connected to one support rod 15, and a scraper 17 is fixedly connected to the other support rod 15. Multiple toothed grooves 18 are provided at both ends of the scraper 17. A spring 13 is fixed within the placement groove 12, and its lower end is fixedly connected to the upper end of the guide rod 14. The guide rod 14 is movable up and down within the placement groove 12, and the spring 13 is fixed to its upper end. Spring 13 is fixed inside placement groove 12. Symmetrical support rods 15 are fixed at the lower end of guide rod 14. Pressure roller 16 rotates on one of the support rods 15, and scraper 17 is fixed on the other support rod 15. Gear groove 18 is opened on the lower edge of scraper 17. In this way, rotating rod 9 drives spring 13 to rotate, and spring 13 drives guide rod 14 to rotate. Guide rod 14 drives two symmetrical support rods 15 to rotate on filter screen 4. Pressure roller 16 presses the foreign objects scooped up by scraper 17 onto filter screen 4. When scraper 17 scrapes up foreign objects, it can make filter screen 4 pass through, thereby accelerating the penetration of solution.

[0024] like Figure 2 As shown, the stirring component includes: a stirring rod 10, which is fixedly installed on the side wall of the rotating rod 9. A stirring blade 11 is fixedly connected to the end of the stirring rod 10, and the stirring rod 10 is inclined downward. The stirring rod 10 is fixed on the side wall of the rotating rod 9. Multiple stirring rods 10 can drive the solution in the storage bottle 2 to be fully mixed in the upper, middle and lower sections. The stirring blade 11 is fixed to the end of the stirring rod 10, which can improve the mixing efficiency of the solution.

[0025] like Figure 2 and Figure 5 As shown, the sealing element includes: a sealing sleeve 5, which is semi-circular and is fitted onto the edge of the liquid storage bottle 2 and the filter bottle 1. A sealing ring 7 is fixedly connected to the inner wall of the sealing sleeve 5, and a fixing handle 6 is fixedly connected to the outer end of the sealing sleeve 5. The cross-section of the sealing sleeve 5 is U-shaped, which wraps around the edges of the liquid storage bottle 2 and the filter bottle 1 from top to bottom. The sealing ring 7 is fixed at both the upper and lower ends of the inner wall of the sealing sleeve 5. When the sealing ring 7 is squeezed, it will deform, thereby achieving a sealing effect and preventing leakage at the connection between the liquid storage bottle 2 and the filter bottle 1. The fixing handle 6 on the outer side of the sealing sleeve 5 facilitates the insertion of the sealing sleeve 5.

[0026] like Figure 3As shown, a baffle 19 is fixedly connected to the inner wall of the filtrate bottle 1. The baffle 19 is located above the suction pipe 20 and is inclined downward. When the solution enters the filtrate bottle 1 from the storage bottle 2, the baffle 19 can prevent the solution from falling to the end of the suction pipe 20 located inside the filtrate bottle 1, thus preventing the suction pipe 20 from drawing out the solution.

[0027] like Figure 2 As shown, the outer connecting end of the suction pipe 20 is folded; the folded suction pipe 20 can form a bend path, thereby preventing the solution from being sucked out.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
