Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for washing. Background Technology

[0002] With the increasing volume of wastewater discharged from industrial production and daily life, how to efficiently treat this type of wastewater to meet environmental protection requirements has become an important issue that urgently needs to be addressed. Wastewater typically contains a large amount of solid impurities, foam, and chemical residues. Direct discharge or improper treatment can not only cause serious environmental pollution but may also adversely affect subsequent wastewater treatment processes.

[0003] Existing wastewater treatment devices for laundry typically employ simple filtration and sedimentation processes, but these methods have several shortcomings in practical applications. During operation, filtration systems easily accumulate debris on the filter screens, making cleaning difficult, leading to bacterial growth and unpleasant odors. Furthermore, the filtered impurities often carry a large amount of wastewater, potentially causing environmental pollution. In addition, the large amounts of foam generated in laundry wastewater, if not effectively treated, will adhere to the surface of the filtration device or float in the water, affecting subsequent treatment effectiveness and potentially causing secondary pollution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater treatment device for washing. A first filter screen traps large particles of impurities, while a hydraulic rod pushes a squeezing plate to the left, cleaning away debris and squeezing out water, thus preventing debris from carrying wastewater and polluting the environment. A transmission mechanism rotates a foam brush to spread foam, and a suction pump draws the foam into a foam collector, achieving efficient treatment and preventing pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for washing, comprising a treatment tank, a squeezing box fixedly connected to the upper end of the outer wall of the treatment tank, an inlet pipe fixedly connected to the front side of the squeezing box, a door rotatably connected to the left end of the squeezing box via a hinge, a hydraulic rod fixedly connected to the inner wall of the right side of the squeezing box, a squeezing plate fixedly connected to the driving end of the hydraulic rod, a first filter screen slidably connected to the rear end of the squeezing box, a motor fixedly connected to the outer wall of the treatment tank, a rotating shaft connected to the driving end of the motor via a linkage assembly, a foam brush fixedly connected to the outer wall of the upper end of the rotating shaft, a second filter screen disposed at the lower end of the foam brush, foam tubes disposed around the upper edge of the second filter screen, a suction pump fixedly connected to the upper end of the foam tubes, a foam collector fixedly connected to one end of the suction pump, a third filter screen disposed at the lower end of the second filter screen, and a stirrer fixedly connected to the outer wall of the lower end of the rotating shaft.

[0006] Furthermore, the linkage component includes a rotating rod fixedly connected to the motor drive end, a second conical wheel fixedly connected to one end of the rotating rod, a first conical wheel meshing with one side of the second conical wheel, and the first conical wheel fixedly connected to the outer wall of the rotating shaft.

[0007] Furthermore, a water outlet pipe is fixedly connected to the lower end of the outer wall of the treatment tank.

[0008] Furthermore, the foam collector is fixedly connected to the top of the processing tank.

[0009] Furthermore, the foam tube passes through the processing chamber and extends to the top of the processing chamber.

[0010] Furthermore, the second filter screen is fixedly connected to the inner wall of the processing chamber, the third filter screen is fixedly connected to the inner wall of the processing chamber, and activated carbon is disposed between the second filter screen and the third filter screen.

[0011] Furthermore, the extrusion plate is slidably connected to the inner wall of the extrusion chamber.

[0012] Furthermore, the right end of the box door is connected to the extrusion box via a switch.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, large particles of impurities are trapped by the first filter screen. Activating the hydraulic rod causes its drive end to push the extrusion plate to the left. During this movement, the extrusion plate not only pushes the filtered impurities to the left end of the extrusion chamber but also cleans the impurities remaining on the first filter screen. When the impurities are pushed to the left end of the extrusion chamber, the extrusion plate applies pressure to them, fully squeezing out the water and preventing the filtered impurities from carrying wastewater and polluting the environment.

[0015] 2. In this invention, a rotating rod is driven by a click drive, which in turn drives the second conical wheel to rotate. Under meshing action, the second conical wheel drives the first conical wheel to rotate, thus causing the rotating shaft to rotate. The rotating shaft then drives the foam brush to rotate, brushing the foam filtered on the second filter screen outwards. A suction pump is then activated, drawing the foam into the foam tube and ultimately into the foam collector for centralized treatment. This design efficiently collects and treats foam, effectively preventing foam residue from polluting water bodies and the environment. Attached Figure Description

The inner wall of the first conical wheel 16 is fixedly connected to the first conical wheel 16. A rotating shaft 9 is fixedly connected to the upper outer wall of the rotating shaft 9. A foam brush 10 is fixedly connected to the lower end of the foam brush 10. A second filter screen 11 is provided at the lower end of the foam brush 10. Foam tubes 13 are provided around the upper end of the second filter screen 11. The foam tubes 13 pass through the treatment box 1 and extend to the top of the treatment box 1. A suction pump 14 is fixedly connected to the upper end of the foam tubes 13. A foam collector 15 is fixedly connected to one end of the suction pump 14. The foam collector 15 is fixedly connected to the top of the treatment box 1. A third filter screen 12 is provided at the lower end of the second filter screen 11. The second filter screen 11 is fixedly connected to the inner wall of the treatment box 1. The third filter screen 12 is fixedly connected to the inner wall of the treatment box 1. Activated carbon is provided between the second filter screen 11 and the third filter screen 12. A stirrer 20 is fixedly connected to the lower outer wall of the rotating shaft 9. A water outlet pipe 19 is fixedly connected to the lower end of the outer wall of the treatment box 1.

[0023] Specifically, when using this device to treat washing wastewater, the wastewater must first be introduced into the squeezing tank 2 through the inlet pipe 3. After entering the squeezing tank 2, the wastewater will be filtered and intercepted by the first filter screen 6, where large particles of impurities are effectively retained. The filtered wastewater then flows into the treatment tank 1. Subsequently, the hydraulic rod 8 is activated, and its drive end pushes the squeezing plate 7 to the left. During the movement, the squeezing plate 7 not only pushes the filtered debris to the left end of the squeezing tank 2, but also cleans the debris remaining on the first filter screen 6. When the debris is pushed to the left end of the squeezing tank 2, the squeezing plate 7 applies pressure to the debris, fully squeezing out the water and preventing the filtered debris from carrying wastewater and polluting the environment. After the squeezing operation is completed, simply operate the switch 5 to open the tank door 4 to clean the debris in the squeezing tank 2. The wastewater entering the treatment tank 1 will first be further filtered by the second filter screen 11, then deeply purified by activated carbon, and then enter the stirring area located below the third filter screen 12. At this time, chemicals need to be added to the wastewater and stirred for reaction. Because wastewater from washing often generates a large amount of foam during treatment, this foam, if not treated promptly, may pollute the water bodies and the environment below. Therefore, the motor 18 is started, its drive end rotates the rotating rod 22, which in turn rotates the second conical wheel 17. Under meshing action, the second conical wheel 17 drives the first conical wheel 16 to rotate, thus rotating the rotating shaft 9. The rotating shaft 9 drives the foam brush 10 to rotate, dispersing the foam brush 10 filtered from the surface of the second filter screen 11. Then, the suction pump 14 is started, drawing the foam into the foam pipe 13, and finally into the foam collector 15 for centralized treatment. This design efficiently collects and treats foam, effectively preventing foam residue from polluting water bodies and the environment. Simultaneously, the rotation of the rotating shaft 9 also drives the agitator 20 to rotate, thoroughly stirring the wastewater and chemicals in the treatment tank 1 to ensure a complete reaction. After the reaction is complete, the treated liquid can be discharged by opening the outlet pipe 19.

[0024] Working Principle: When using this device, wastewater first enters the squeezing tank 2, where it passes through the first filter screen 6 to intercept large particles of impurities, effectively separating solid waste from liquid. The filtered wastewater then enters the treatment tank 1. At this time, the hydraulic rod 8 is activated, pushing the squeezing plate 7 to squeeze and dehydrate the filtered solid impurities, ensuring that the water content of the solid waste is reduced to a minimum to avoid environmental pollution. The wastewater then enters the treatment tank 1 and passes through the second filter screen 11, the activated carbon adsorption layer, and the third filter screen 12 in sequence, effectively removing suspended solids, organic pollutants, and fine particulate matter. In the stirring reaction zone, treatment agents are added, and the stirring device is activated to ensure thorough mixing and reaction. Since washing wastewater usually produces a large amount of foam, the linkage component driven by the motor 18 drives the foam brush 10 to remove the foam from the filter screen surface. At the same time, the suction pump 14 is activated to transport the foam to the foam collector 15 for centralized treatment, preventing the foam from affecting subsequent treatment processes.
