Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, and in particular to an experimental device for comparing the performance of water treatment filter media. Background Technology

[0002] Water treatment filter media are filtration materials used in water treatment systems. Their main function is to remove suspended solids, organic matter, microorganisms and other pollutants from water through mechanisms such as physical interception, adsorption and sedimentation.

[0003] Common water treatment equipment includes multi-media filters, which primarily use multiple layers of filter media with different particle sizes and densities to remove suspended solids, particles, and impurities from water. Filter media typically include quartz sand, anthracite, activated carbon, magnetite, garnet, porous ceramics, and plastic balls. The different specific gravities, particle sizes, and thicknesses of these filter media result in varying filtration effects. To verify the impact of filter media type, particle size, and thickness on the filtration efficiency for suspended solids, particles, and impurities in water, relevant experiments are required.

[0004] Experiments to verify the effects of filter media type, particle size, and thickness on the filtration efficiency of suspended solids, particles, and impurities in water require wastewater filtration experiments with various different filter media, while maintaining a consistent influent rate. Laboratory conditions are limited, making it difficult to verify excessively thick filter media, and the operation is complex with challenges in controlling variables. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a comparative experimental device for water treatment filter media performance, which facilitates related operations in the laboratory and further improves experimental efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An experimental apparatus for comparing the performance of water treatment filter media includes a water tank and an inlet pipe. Experimental liquid is pumped into the water tank through the inlet pipe. The water tank is arranged at an angle and has a notch at the bottom. A fin-shaped groove is provided on the outer side of the lower end of the water tank. The fin-shaped groove includes a guide part opposite to the notch and a storage part installed at the lower end of the guide part. The guide part and the storage part form a receiving chamber for accommodating filter media. The side of the storage part away from the guide part is rotatably connected to the lower end of the water tank. The guide part is fin-shaped, and the lateral dimension of the upper end of the guide part is smaller than the lateral dimension of the lower end of the guide part. The storage part is connected to a drain pipe for discharging the experimental liquid.

[0008] Preferably, a locking device and a sealing structure are provided between the flow guide and the water tank.

[0009] Preferably, a support plate is provided at the lower end of the water tank, and a bracket is provided between the water tank and the support plate to adjust the tilt of the water tank.

[0010] Preferably, the upper surface of the support plate is provided with a plurality of limiting grooves, and the lower end of the bracket is provided with a limiting protrusion that matches the limiting grooves.

[0011] Preferably, the bottom of the guide section is arc-shaped, and the drain pipe is opposite to the lowest point of the arc of the guide section.

[0012] Preferably, the inlet pipe is connected in series with a peristaltic pump for pumping the experimental liquid.

[0013] Preferably, the water tank is further provided with a baffle, which is located on the upper surface of the storage section.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] By incorporating a tilted water tank and fin-shaped grooves, a larger amount of filter media can be filled into the storage compartment to form a thicker filter media layer, facilitating laboratory operations. Simultaneously, the guide section directs the incoming liquid, ensuring precise and stable liquid entry. Furthermore, by controlling the fin grooves away from the water tank, the liquid is controlled to clean the storage compartment from the drain pipe, rapidly discharging the filter media. The guide section further guides the discharged filter media, increasing the discharge rate and facilitating related laboratory operations, thus improving experimental efficiency.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0024] To address the problems mentioned in the background art, see Appendix Figure 1 - Appendix Figure 5 A water treatment filter media performance comparison experimental device includes a water tank 3 and an inlet pipe 2. The experimental liquid is pumped into the water tank 3 through the inlet pipe 2. The water tank 3 is arranged at an inclination, and the experimental liquid located at the higher position of the water tank 3 can flow downward under the action of gravity. There is a notch at the bottom of the water tank 3, and a fin groove 4 is provided on the lower outer side of the water tank 3. The fin groove 4 includes a guide part 401 opposite to the notch and a storage part 402 installed on the lower side of the guide part 401. The guide part 401 and the storage part 402 form a receiving chamber for accommodating the filter media. By setting the guide part 401, the experimental liquid can be guided and uniformly guided into the storage part 402 for filtration by the filter media for comparison.

[0025] The storage section 402 is rotatably connected to the lower end of the water tank 3 on the side away from the guide section 401. The guide section 401 is fin-shaped, and the lateral dimension of the upper end of the guide section 401 is smaller than the lateral dimension of the lower end of the guide section 401. The storage section 402 is connected to a drain pipe 8 for discharging experimental liquid.

[0026] During the experiment, the fin groove 4 is controlled to fit against the lower end of the water tank 3 to prevent the experimental liquid from flowing out from the gap at the bottom of the water tank 3. The experimental liquid can pass through the guide part 401 and the storage part 402 from top to bottom and finally be discharged from the drain pipe 8. By testing the filtered liquid at the drain pipe 8, the filtration performance of the filter media in different storage parts 402 can be compared, realizing rapid comparison. During the experiment, the guide part 401 can accurately guide the experimental liquid to ensure the accuracy of the experiment.

[0027] After the experiment, the control fin groove 4 is separated from the water tank 3. The position of the control guide part 401 is lower than that of the storage part 402. The cleaning liquid is pumped in reverse from point 8, which can quickly discharge the filter media in the storage part 402. During this process, the guide part 401 in the fin state can also play a role in guiding the filter media, so as to achieve the rapid discharge of the filter media.

[0028] When multiple fin grooves 4 are arranged side by side, a water distributor 9 can be installed at the top of the water tank 3. The water inlet pipe 2 is connected to the water distributor 9. The water distributor 9 can disperse the liquid, and the dispersed liquid can flow along the inclined water tank 3 to achieve precise dispersion and guidance, ensuring the accuracy of subsequent experimental results.

[0029] A locking device and a sealing structure are provided between the flow guide 401 and the water tank 3. The locking device ensures the stability between the fish fin groove 4 and the water tank 3, and the sealing structure ensures a certain degree of liquid sealing and enhances the sealing effect at the connection. The locking device can be an existing locking buckle or a magnetic buckle, and the sealing structure is a sealing ring. The direction of the sealing ring is adapted to the shape of the bottom cut of the water tank 3.

[0030] A support plate 6 is provided at the lower end of the water tank 3, and a bracket 5 is provided between the water tank 3 and the support plate 6 to adjust the inclination of the water tank 3. By adjusting the inclination of the water tank 3, the flow rate of the water can be adjusted to meet the process effect of different types of filter media. In particular, when the filter media filters slowly, it can prevent the experimental liquid from not being able to completely enter the storage section 402 for filtration, thus avoiding affecting normal filtration.

[0031] Furthermore, the upper surface of the support plate 6 is provided with several limiting grooves 601, and the lower end of the bracket 5 is provided with limiting protrusions 501 that are adapted to the limiting grooves 601. By controlling the limiting protrusions 501 to be opposite to different limiting grooves 601, the two can be controlled to engage. Through the above structural settings, the friction between the limiting protrusions 501 and the limiting grooves 601 can be increased, the support effect can be enhanced, and accidents can be avoided during the filtration experiment.

[0032] Furthermore, the bottom of the guide section 401 is arc-shaped, and the drain pipe 8 is opposite to the lowest point of the arc of the guide section 401. The arc-shaped bottom of the guide section 401 can better guide the experimental liquid and filter media. In addition, the drain pipe 8 is opposite to the bottom of the guide section 401, and the reverse cleaning liquid at the drain pipe 8 can push the filter media in the fin groove 4. The overall friction is smaller, which can realize the rapid discharge of the filter media and avoid the impact.

[0033] A peristaltic pump 1 is connected in series in the water inlet pipe 2 to pump the experimental liquid. By setting 1, the pumping volume and rate of the experimental pump can be precisely controlled, ensuring the accuracy of the experiment.

[0034] Inside the water tank 3, a baffle 7 is also installed. The baffle 7 is located on the upper surface of the storage section 402. By setting the baffle 7, the upper part of the storage section 402 can be blocked during the experiment to prevent the filter material from being discharged under the flushing of the experimental liquid. At the same time, at the beginning of the experiment, the baffle 7 can be opened to realize the rapid addition of filter material, which further improves the efficiency of the experiment. The baffle 7 and the water tank 3 can also be connected by magnetic buckles or other means to ensure the stability and sealing of the connection.

[0035] Finally, it should be noted that...

[0036] 1. The bracket 5 is made of soft PVC material, which has a certain degree of elasticity. It can be fixed by pinching the lower end and aligning it with the corresponding limiting groove 601. The limiting groove 601 in different positions corresponds to different slopes.

[0037] 2. Adjust the slope of the plastic water tank by adjusting the bracket 5 at different positions in the limiting groove 601, thereby adjusting the water flow speed.

[0038] 3. The peristaltic pump 1 is used to draw wastewater for testing, and the water distributor 9 makes the wastewater flow evenly and flat into the plastic water tank, making the water distribution more uniform.

[0039] 4. The upper end of the fish fin groove 4 is smooth and downward, forming an arc-shaped guide section. The arc-shaped guide section guides all the sewage on the upper side to the filter media, so that the filter media and sewage are in full contact, ensuring the accuracy of the experiment. The maximum tangent angle of the arc-shaped guide section should be greater than 60° to ensure the uniformity and stability of the filter media in the tank. The bottom end of the groove is vertical, serving as the filter media storage section. The water tank 3 is equipped with multiple continuous fish fin grooves 4, which can simultaneously test multiple different filter media.

[0040] 5. A drain pipe is provided at the bottom vertical part of the fin groove 4. The diameter of the drain pipe is ≤1cm and a filter screen is installed (the filter screen pore size is lower than the filter media gradation) to prevent the filter media from flowing out of the pipe.

[0041] 6. The filtered wastewater flows out through drain pipe 8. The experimenters collect it in a clean beaker, measure relevant parameters, and judge the filtration effect of different filter media.

[0042] 7. The size of the groove baffle 7 should cover the lower half of the fin groove 4 to prevent the filter media from tipping over and falling out of the storage part of the fin groove 4.

[0043] 8. The thickness of the filter media can be adjusted by varying the amount of filter media added, thereby improving experimental efficiency and the feasibility of laboratory research on filter media with higher thicknesses.

[0044] 9. The tilt angle can be adjusted by adjusting the bracket to control the water flow speed, thereby improving the experimental efficiency and accuracy of comparing the filtration performance of various filter media.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
