Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment in environmental monitoring laboratories, in particular to a wastewater treatment machine for experiments. Background Art

[0002] The environmental monitoring laboratory is an important environmental protection organization that is responsible for monitoring and analyzing environmental pollutants. Laboratory wastewater also contains various organic, inorganic and heavy metal pollutants. If not properly treated, it will cause serious harm to the environment and human health. Effective treatment of environmental monitoring laboratory wastewater is an important measure to protect the environment and human health.

[0003] Prior art, for example, the patent with announcement number "CN218860517U" discloses a laboratory environment detection wastewater treatment device, which treats wastewater by filtering, neutralizing, settling and sterilizing, and reasonably reaches the discharge index. However, the multiple filter plates of the above patents are embedded in the pipeline, and the filtered objects are easy to adhere to the filter screen and cause blockage; for example, the patent with announcement number "CN220047275U" discloses a sewage treatment device for an environmental monitoring laboratory. In the actual process of filtering sewage, the scraper bar is driven by the connecting rod to rotate inside the sewage treatment cylinder, so as to facilitate the scraping of dirt attached to the filter screen, so as to keep the whole filtering process smooth and prevent The invention can prevent the filter from being blocked and affecting the actual filtering efficiency, and the setting of the limit mechanism makes it easy to disassemble the cover plate and the water inlet, and at the same time, combined with the setting of the auxiliary rod, it is easy to loosen the limit of the filter and fully clean the inside of the sewage treatment cylinder and the filter. Although the above patent solves the problem of easy adhesion on the filter, the filter needs to be disassembled when cleaning the filter, which is time-consuming and laborious, and it takes a time period to clean the filter once. The filtered material adhered to the filter is easy to harden on the filter after long-term adhesion, and the filter is not easy to clean. Moreover, the filtered material under cleaning may carry toxic substances or chemicals, and cannot be cleaned according to the cleaning method of ordinary garbage. Utility Model Content

[0006] The working principle of the utility model is as follows: laboratory waste water is poured in from the water inlet, and the laboratory waste water flows to the inner bottom of the machine body after being filtered through the filter plate. After the laboratory waste water completely flows through the filter plate, the cleaning mechanism is started, and the cleaning mechanism begins to clean the filter material adhering to the filter plate. The filter material reaches the filter press box along with the cleaning mechanism, and the hydraulic cylinder and the rotating motor are started at this time. The pressing plate descends and rotates at the same time to repeatedly squeeze the filter material, and the water squeezed out returns to the machine body through the bottom of the filter box. At this time, the filter material that has passed the filter press is close to a dry state. At this time, the drawer is opened, and the dry filter material cake is directly taken out for direct treatment, and the drawer can be put back in place for continued use.

[0007] The beneficial effects of the utility model are as follows: in the process of filtering laboratory wastewater, a cleaning mechanism and a filter pressing mechanism are added, so that the filtered material on the filter screen can be cleaned in time, avoiding the situation where the filter screen is blocked and the wastewater is blocked. After cleaning, the filtered material can be pressed out of water in time by the filter pressing mechanism and formed into a fixed shape, which is convenient for subsequent removal.

[0008] Furthermore, the cleaning mechanism includes a linear motor and a brush, wherein the linear motor is connected to the top of the machine body, and the output shaft of the linear motor is connected to a downward connecting rod, and the bottom end of the connecting rod is connected to the brush. Through the arrangement of the brush, the filtered matter on the filter plate can be cleaned into the filter press box.

[0009] Further, both sides of the top in the drawer are provided with slide rails, and the extrusion plate is connected to the top in the drawer through the slide rails. Through the arrangement of the slide rails, the extrusion plate can be taken out from the drawer.

[0010] Furthermore, a small filter screen is provided at the bottom of the drawer, and the size of the small filter screen is consistent with the size of the connection between the bottom of the filter press box and the body. Through the provision of the small filter screen, the fine filtered matter in the filter press box that is squeezed and falls to the bottom of the drawer can be blocked.

[0011] Furthermore, a plurality of rotating discs are symmetrically arranged at the bottom of the body, one of which is connected to the output shaft of a small motor, and a plurality of rotating discs are connected to stirring blades, and the free ends of the plurality of stirring blades are connected through transmission blades. Through the arrangement of the stirring blades and the transmission blades, the rotation of one of the rotating discs drives the stirring blades to rotate, and the rotation of the stirring blades drives the other stirring blades to rotate through the transmission blades, so that the wastewater inside the body can be fully stirred.

[0012] Furthermore, the outer wall of the drawer is connected with a handle. The arrangement of the handle makes it more convenient to take the drawer. BRIEF DESCRIPTION OF THE DRAWINGS
