Description

Technical Field

[0001] The utility model relates to the technical field of sewage pretreatment, and more specifically, to an ozone-oxidized chemical sewage pretreatment device. Background Art

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water, etc. discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thus endangering human health and affecting industrial and agricultural production. The main defects of the sewage pretreatment devices currently widely used are mainly reflected in insufficient dissolution when using reagents, difficulty in cleaning the equipment after sewage pretreatment, and inability to treat toxic gases generated during the treatment process.

[0003] After searching, the Chinese patent with publication number CN210313679U discloses an ozone oxidation chemical wastewater pretreatment equipment. On the one hand, the equipment completes the batch addition of different drugs in the wastewater treatment process by setting up a drug feeding box. On the other hand, it is provided with a drug feeding cover to prevent the escape of harmful gases after the drug feeding is completed. Secondly, a motor is provided, and the motor is movably connected with a stirring blade to complete the stirring of the treated wastewater, so that the drugs are mixed more evenly.

[0004] However, when this structure is actually used, since the stirring blades inside the shell do not completely cover all the space inside the shell, when the medicine is put into the shell through the feeding port, the medicine will be stirred unevenly, thereby reducing the final effect of sewage treatment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an ozone-oxidized chemical wastewater pretreatment device to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the stirring mechanism includes a rotating shaft, which is arranged inside the shell, and one end of the rotating shaft is provided with a connecting bent rod, and fixed disks are provided on the outer sides of both ends of the connecting bent rod, and a fixing plate is provided on the outer side of the fixing plate, and a connecting groove is provided on the surface of the fixing plate, and the number of the connecting grooves is set to be several, one end of the fixing plate is fixedly connected to the outer surface of the fixing disk, and a rectangular plate is provided on the outer side of the connecting bent rod, and a rectangular groove is provided on the surface of the rectangular plate, and the number of the rectangular grooves is set to be several, one side of the rectangular plate is fixedly connected to the outer surface of the connecting bent rod, and one end of the connecting bent rod is provided with a fixing seat, and one side of the fixing seat is fixedly connected to the inner wall of the shell, and one end of the connecting bent rod is movably connected to the fixing seat.

[0008] Through the above scheme, it can be seen that by installing a rotating shaft at the output end of the motor, the motor drives the connecting bent rod to rotate. At this time, the fixed plates on the outside of the two ends of the connecting bent rod will rotate with the connecting bent rod, thereby driving the fixed plate to stir the sewage inside the outer shell. During the stirring process, the middle section of the connecting bent rod will drive the rectangular plate to rotate, thereby realizing that the rectangular plate drives the sewage in the middle section of the outer shell to rotate. At this time, the rotation amplitude of the sewage in the middle section of the outer shell is different from that of the sewage on both sides, thereby improving the fusion effect of the sewage inside the outer shell and the medicine through impact, thereby improving the practicability of the device.

[0009] Preferably, a slide groove is provided on the top of the shell, and a protective cover is installed inside the slide groove, and the protective cover is movably connected to the slide groove, and an extension plate is provided on one side of the protective cover, and a circular hole is provided on the surface of the extension plate, and a fixed socket is provided on the top surface of the shell, and the extension plate and the fixed socket are detachably connected, and a limiting slide groove is provided on the top surface of the shell, and a movable card cover is provided inside the limiting slide groove, and one end of the movable card cover is movably connected to the limiting slide groove, and a fixing rod is provided on one side of the shell, and a fixing protrusion is provided on the bottom side of the movable card cover, and a threaded groove is provided on the surface of the fixing protrusion, and a feeding port is provided on the top of the shell, and the cross-sectional shape of the feeding port is set to be rectangular.

[0010] Through the above scheme, it can be seen that by opening a limiting slide groove on the top surface of the shell, and then utilizing the characteristic that one end of the movable card cover is movably connected to the limiting slide groove, the movable card cover and the ladder can be separated by manually pushing and pulling the movable card cover, and the fixed rod is overlapped with the fixed protrusion on the outside of the movable card cover, so that the position of the movable card cover can be fixed by connecting the screw and the threaded hole, thereby improving the stability of the device. The movable card cover can prevent the ladder from being corroded by rainwater, thereby improving the practicality of the device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a stirring mechanism, compared with the prior art, a rotating shaft is installed at the output end of the motor, and then the motor drives the connecting bent rod to rotate. At this time, the fixed plates on the outer sides of the two ends of the connecting bent rod will rotate with the connecting bent rod, thereby driving the fixed plate to stir the sewage inside the shell. During the stirring process, the middle section of the connecting bent rod will drive the rectangular plate to rotate, so that the rectangular plate drives the sewage in the middle section of the shell to rotate. At this time, the rotation amplitude of the sewage in the middle section of the shell is different from that of the sewage on both sides, thereby improving the fusion effect of the sewage inside the shell and the medicine through impact, thereby improving the practicality of the device;

[0013] 2. By setting up an active card cover and opening a limiting slide groove on the top surface of the shell, and then utilizing the feature that one end of the active card cover is movably connected to the limiting slide groove, the active card cover and the ladder can be separated by manually pushing and pulling the active card cover, and the position of the active card cover can be fixed by overlapping the fixing rod with the fixing protrusion on the outside of the active card cover, thereby connecting the screw and the threaded hole, thereby improving the stability of the device, and preventing the ladder from being corroded by rainwater through the active card cover, thereby improving the practicality of the device.
