Description

Technical Field

[0001] The utility model belongs to the technical field of resin production waste treatment, and particularly relates to a resin wastewater treatment device. Background Art

[0002] Resin generally refers to an organic polymer that softens or melts within a certain temperature range when heated, has a tendency to flow under the action of external force during softening, and is solid, semi-solid, or sometimes liquid at room temperature. A large amount of wastewater is generated during the production process of resin. These wastewaters usually need to be treated before being discharged to prevent environmental pollution. The wastewater generally undergoes treatment steps such as solid-liquid separation, biochemical treatment, oxidation treatment, and flocculation precipitation. For example, an organic resin production wastewater treatment system disclosed in the patent with the application number CN202120588663.5 includes a wastewater treatment tank. A mixing rotating shaft is rotatably arranged between the upper and lower wall bodies of the wastewater treatment tank. The top end of the mixing rotating shaft extends out from the top of the wastewater treatment tank and is power-connected to a mixing motor.

[0043] Embodiment 1:

[0044] The embodiment of this application provides a resin wastewater treatment device, including: a filter box 1, a wastewater treatment chamber 2 is arranged inside the filter box 1, and a drain pipe 3 is arranged at the bottom of the filter box 1;

[0045] It further includes: a wastewater inlet 4, the wastewater inlet 4 is arranged at the top of the filter box 1 and communicates with the wastewater treatment chamber 2; a first wastewater filtration mechanism 5, the first wastewater filtration mechanism 5 includes a filter screen 50 arranged at the wastewater inlet 4 and a cleaning brush 51 for cleaning the filter screen 50; a second wastewater filtration mechanism 6, the second wastewater filtration mechanism 6 is arranged in the wastewater treatment chamber 2;

[0046] The second wastewater filtering mechanism 6 is located below the filter screen 50 .

[0047] In this embodiment, during the treatment of resin wastewater, the wastewater is passed into the wastewater inlet 4. After entering the wastewater inlet 4, the wastewater falls on the filter screen 50, and the impurities in the wastewater are filtered by the filter screen 50. Then the wastewater passes through the filter screen 50 and enters the wastewater treatment chamber 2. The second wastewater treatment mechanism can filter the impurities in the wastewater again. Finally, the wastewater falls on the bottom of the filter box 1 and is discharged through the drain pipe 3. After the wastewater is discharged from the drain pipe 3, it moves to the next treatment process. After filtering more impurities on the filter screen 50, the cleaning brush 51 can clean the filter screen 50 to prevent the filter screen 50 from being blocked. Compared with the prior art, the utility model effectively improves the treatment efficiency of wastewater.

[0048] Embodiment 2:

[0049] This embodiment provides a resin wastewater treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the first wastewater filtering mechanism 5 also includes: a rotating motor 52, which is fixedly arranged in the wastewater inlet 4 through a mounting frame; a debris discharge port 53, which is arranged on one side of the filter box 1 and communicated with the wastewater inlet 4;

[0050] The driving end of the rotating motor 52 is connected to the center of the cleaning brush 51 to drive the cleaning brush 51 to rotate.

[0051] The first wastewater filtering mechanism 5 further includes: a tooth plate 54, which is movably disposed on the cleaning brush 51 and is located on the inner side of the cleaning brush 51, and the tooth plate 54 can move toward the outer end of the cleaning brush 51 as the rotation speed of the cleaning brush 51 increases;

[0052] The tooth plate 54 is located below the cleaning brush 51 and the bristles of the cleaning brush 51 can be moved during the movement of the tooth plate 54 .

[0053] Moreover, two guide grooves 55 are provided on the surface of the cleaning brush 51. The two guide grooves 55 are symmetrically distributed along the length direction of the cleaning brush 51 with the center of the cleaning brush 51 as the symmetry point. A moving block and a return spring 56 are installed in the guide groove 55. The two ends of the return spring 56 are respectively connected to the guide groove 55 and the moving block. A support frame 57 is installed on the moving block. The two ends of the support frame 57 extend downward, and the two ends of the tooth plate 54 are connected to the two ends of the support frame 57.

[0054] In this embodiment, after a large amount of impurities are filtered out of the filter screen 50, the rotating motor 52 is started to drive the cleaning brush 51 to rotate. The bristles on the cleaning brush 51 can clean the impurities filtered out and attached to the surface of the filter screen 50. The cleaned impurities are driven by the continuously rotating cleaning brush 51 to gradually move toward the edge of the wastewater inlet 4, and finally move to the impurity discharge port 53 and be discharged from the impurity discharge port 53.

[0057] The squeezing frame 63 can continuously squeeze the water-absorbing and filtering sponge 62 during the reciprocating movement, and an opening corresponding to the maintenance hole 65 is opened on the side of the placement frame 60 .

[0058] The sealing strip 7 further comprises: a slot 8 , which extends axially along the sealing strip 7 , has a cross section in an isosceles trapezoid, and is arranged on the sealing surface of the sealing strip 7 .

[0059] Moreover, an elastic reset member 9 is installed between the extrusion frame 63 and the placement frame 60. The elastic reset member 9 can be a conventional elastic telescopic rod. A drive motor 10 is installed in the wastewater treatment chamber 2. An eccentric wheel 11 is installed on the driving end of the drive motor 10.

The extrusion frame 63 reciprocates in the vertical direction through the eccentric wheel 11 and the elastic reset member 9.

[0060] In this embodiment, the wastewater falls into the wastewater treatment chamber 2 after being treated by the first wastewater filtration mechanism 5. After the wastewater lands on the extrusion frame 63, it passes through a number of second water passing holes 64 and is absorbed by the water absorption and filtration sponge 62. Then, the extrusion frame 63 reciprocates in the vertical direction to squeeze the water absorption and filtration sponge 62. The wastewater absorbed by the water absorption and filtration sponge 62 is squeezed out of the sponge and lands on the bottom of the filtration box body 1, and finally is discharged by the drain pipe 3. The water absorption and filtration sponge 62 can effectively filter the tiny impurity particles in the wastewater, thus facilitating the subsequent treatment process of the wastewater and further improving the filtration effect of the wastewater. By opening the sealing door 66, the water absorption and filtration sponge 62 can be taken out from the maintenance hole 65 for replacement. After the water absorption and filtration sponge 62 is replaced, the sealing door 66 is closed again. The slot 8 on the sealing strip 7 can effectively improve the sealing effect of the sealing strip 7. When the wastewater penetrates into the slot 8, it will accumulate in the slot 8. After the wastewater fills the slot 8, it can squeeze the sealing strip 7, so that the sealing surface of the sealing strip 7 is tighter, reducing the occurrence of leakage and improving the sealing effect of the sealing strip 7.
