Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment experiments, in particular to a sewage treatment experiment box. Background Art

[0002] The recycling of water resources has always received widespread attention from all walks of life. In order to better treat various sewage and improve the purification effect, researchers will collect data through various sewage treatment experiments for evaluation. In the prior art, such as the patent technology of patent number CN208485619U, a simple treatment box for sewage treatment experiments is proposed, including a positioning component, a device body and a mounting plate, etc. The device body also includes a static transparent box, a box cover, a suction pipe, a filter bucket and a pin rod, etc. The suction pipe is fixed by a mounting plate and a rubber ring, and the position of the nut on the screw is changed at the same time to achieve the purpose of adjusting the suction height. No manual support is required, manpower is saved, and the suction quality is improved. The problem of the lack of suction positioning function in the original simple treatment box for sewage treatment experiments is solved. When using an external suction pump to extract the stratified sewage, it is necessary to support the suction pipe for a long time, which is not only labor-intensive, but also uncomfortable. It is easy to bring out a large amount of bottom sludge due to hand shaking, which has a great impact on the experimental results.

[0003] However, the above technical solution still has shortcomings. Since the design relies on a suction tube to absorb the upper clear liquid and there is no blocking component, when the suction port of the suction tube comes into contact with the flocculent precipitate in the lower layer, the precipitate will still be sucked away, causing solid precipitates to still exist in the sucked out filtrate, affecting the filtration effect. At the same time, since there is still a large amount of liquid in the precipitate after the reaction that has not been extracted, only extracting the upper layer of liquid will greatly affect the sewage treatment data, and it is impossible to accurately record the degree of sewage pollution or the effect of sewage treatment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-5The cam 35 is provided with a plurality of cams 36, 37 and 38, and the cam 36 is provided with a plurality of cams 37. The cam 36 is provided with a plurality of cams 38, and the cam 36 is provided with a plurality of cams 38. The cam 36 is provided with a plurality of cams 38, and the cam 36 is provided with a plurality of cams 38. When in use, first put chemical reagents into the experimental box body 1 to purify sewage. After the reaction produces solid precipitation at the bottom of the box, the bottom plate 4 is pulled out to leak out the filter plate 5. The filter plate 5 separates the solid precipitation from the purified water. At this time, turn on the pump to quickly separate the water and the precipitation through the suction pipe 7 to improve the filtration efficiency. After most of the liquid is sucked out, move the slide rod assembly 3 to squeeze the solid precipitation downward through the pressure plate 8 to further squeeze out the liquid. This design not only avoids the problem of the suction pipe 7 in the original design that the solid precipitation is easily extracted, but also can provide accurate data of sewage and purified water, thereby ensuring the data accuracy of the sewage treatment experiment.

[0026] like Figure 4 As shown, further, the interior of the experimental box body 1 is cylindrical, and one side of the pressure plate 8 matches the curvature of the inner wall of the experimental box body 1. The pressure plate 8 matches the interior of the experimental box body 1, and the user presses the button block 32 by hand to drive the slider 34 to separate from the top cover 2, and the slide bar assembly 3 can slide freely. The solid precipitate is squeezed by the pressure plate 8, and the liquid in the solid precipitate can be squeezed out to measure the water quality data after sewage purification, thereby ensuring the accuracy of the experimental data.

[0027] like Figure 3 As shown, the slider 34 is in a triangular prism shape, and the inclined surface of the slider 34 is facing upward. Pressing the button block 32 drives the slider 34 to separate from the top cover 2. After use, the slide bar assembly 3 is slid upward to make the inclined surface of the slider 34 abut against the top cover 2. Since the inclined surface of the slider 34 is facing upward, the top cover 2 squeezes the slider 34, making it easy for the slider 34 to be re-inserted into the top cover 2, thereby optimizing the convenience of use.

[0028] like Figure 2As shown, further, a shovel blade 13 is fixedly connected to the side wall of the experimental box body 1, and the blade edge of the shovel blade 13 abuts against the upper surface of the bottom plate 4. A baffle bar 9 is fixedly connected to one side of the upper surface of the bottom plate 4. A rubber sealing ring 10 is fixedly connected to the opening of the experimental box body 1 and the bottom plate 4. When the bottom plate 4 is pulled, the shovel blade 13 scrapes out the sediment on the surface of the bottom plate 4, and the two ends of the baffle bar 9 are fixedly connected to the upper surface of the bottom plate 4, leaving a distance between the middle and the upper surface of the bottom plate 4, so as to facilitate the scraping of solids and prevent the bottom plate 4 from being pulled out. The rubber sealing ring 10 prevents the outflow of water when pulling.

[0029] like Figure 1 As shown, further, the filter plate 5 includes a frame 51 and a filter layer 52, and the filter layer 52 is plugged into the frame 51. The pluggable filter plate 5 is convenient for replacing the filter layer 52 after each experiment, thereby optimizing the convenience of use of the device.

[0030] like Figure 1 and Figure 2 As shown, further, the outer surface of the bottom plate 4 is connected to a first handle 11, and the outer surface of the filter plate 5 is connected to a second handle 12. This design sets force application points on the outer sides of the bottom plate 4 and the filter plate 5, which is convenient for the user to apply force to pull the bottom plate 4 and the filter plate 5, further optimizing the use experience.

[0031] Working principle: When in use, first put chemical reagents into the experimental box body 1 to purify sewage. After the reaction produces solid precipitation at the bottom of the box, the bottom plate 4 is pulled out to leak out the filter plate 5. The filter plate 5 separates the solid precipitation from the purified water body. At this time, turn on the pump to quickly separate the water body and the precipitation through the suction pipe 7 to improve the filtration efficiency. After most of the liquid is sucked out, the user presses the button block 32 by hand to drive the slider 34 to detach from the top cover 2, and the slide bar assembly 3 can slide freely. The moving slide bar assembly 3 squeezes the solid precipitation downward through the pressure plate 8 to further squeeze out the liquid. This design not only avoids the problem that the suction pipe 7 in the original design easily extracts the solid precipitation, but also can provide accurate data of sewage and purified water, thereby ensuring the data accuracy of the sewage treatment experiment.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
