Description

Technical Field

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

[0002] Wastewater treatment refers to the technical process of removing or converting pollutants in wastewater into harmless substances through a series of physical, chemical and biological methods, so that the treated water quality meets the discharge standards or reuse standards.

[0003] Reference patent CN202482123U discloses a rapid-assembly modular non-powered biological filter bed, belonging to the field of wastewater treatment technology. This rapid-assembly modular non-powered biological filter bed includes a bed body with an inlet and an outlet. Artificial filler modules are installed within the bed body. Each artificial filler module consists of at least two layers of unit tanks filled with internal filler material, and the unit tanks are interconnected through permeable holes around their perimeter. This utility model not only improves water treatment efficiency but also facilitates installation, maintenance, disassembly, and cleaning, while saving costs.

[0004] The aforementioned patent utilizes the gaps between the packing materials to filter sewage, which saves on treatment costs compared to traditional filtration methods. However, after prolonged use, the packing materials accumulate a lot of dirt inside, requiring manual cleaning or replacement. This makes subsequent maintenance inconvenient and labor-intensive. To address these issues, we propose a modular combined sewage treatment integrated device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular integrated wastewater treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular integrated wastewater treatment device includes a wastewater treatment tank with a sedimentation tank inside. A sand washing assembly is provided on the side of the sedimentation tank. The sand washing assembly includes a sand washing trough, a first conveying cylinder, and a second conveying cylinder. A first motor is fixedly installed on the upper end of the first conveying cylinder, and a first rotating shaft is fixedly installed on the output end of the first motor. A first conveying auger is fixedly connected to the outer wall of the first rotating shaft. A second motor is fixedly installed on the upper end of the second conveying cylinder, and a second rotating shaft is fixedly installed on the output end of the second motor. A second conveying auger is fixedly connected to the outer wall of the second rotating shaft. A sand injection pipe is connected to the side of the first conveying cylinder, and a receiving pipe and a delivery pipe are respectively connected to the upper and lower sides of the second conveying cylinder. The sand injection pipe is inserted into the inner side of the receiving pipe.

[0008] Furthermore, both the settling tank and the washing tank are filled with coarse sand.

[0009] Furthermore, two sets of sand-washing rollers are rotatably installed inside the sand-washing trough, and an external motor is fixedly installed on the outer wall of the sand-washing trough. The output end of the external motor rotates through to the inside of the sand-washing trough and is connected to the sand-washing roller shaft coupling.

[0010] Furthermore, an installation plate is fixedly connected between the first conveying cylinder and the upper side of the sand washing tank, and a vertical plate is fixedly connected between the second conveying cylinder and the side wall of the sewage treatment tank.

[0011] Furthermore, a bottom support is fixedly connected to the bottom of the sand washing trough, a mesh plate is fixedly installed at the upper port of the bottom support, a drain outlet is connected to the lower side of the bottom support, a first solenoid valve is fixedly installed on the drain outlet, and a second solenoid valve is fixedly installed on the discharge pipe.

[0012] Furthermore, an inlet pipe and an outlet pipe are respectively connected and installed on both sides of the sewage treatment tank.

[0013] Furthermore, fine holes are provided on the side wall of the sedimentation tank, and a sleeve is fixedly connected to the upper side of the sedimentation tank. The sleeve is screwed onto the upper side of the sewage treatment tank.

[0014] Furthermore, a control switch is fixedly installed on the side wall of the sewage treatment tank.

[0015] Compared with related technologies, the modular combined wastewater treatment integrated device proposed in this utility model has the following beneficial effects:

[0016] In this utility model, a modular integrated wastewater treatment device is described. Through a sand-washing component, both a sedimentation tank and a washing tank are filled with coarse sand. The coarse sand in the sedimentation tank is responsible for adsorbing and filtering dirt in the water, while the coarse sand in the washing tank is cleaned by an externally driven washing roller. The coarse sand conveyed from the washing tank by a second conveyor is then washed clean. Subsequently, the coarse sand in the washing tank is conveyed to the first conveyor. The second motor reverses the direction of the conveying auger in the second conveyor, causing the coarse sand injected by the first conveyor to be conveyed from the upper side of the second conveyor to the sedimentation tank. This completes the cleaning and replacement of the coarse sand in the sedimentation tank, maintaining a good filtration and adsorption effect and improving the purification efficiency of wastewater. Furthermore, the entire coarse sand replacement and cleaning process is completed automatically by machinery, reducing manual labor and enhancing practicality. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-6 A modular integrated wastewater treatment device includes a wastewater treatment tank 1, a sedimentation tank 2 inside the wastewater treatment tank 1, and a sand washing assembly 6 on the side of the sedimentation tank 2. The sand washing assembly 6 includes a sand washing trough 61, a first conveying cylinder 67, and a second conveying cylinder 615. A first motor 69 is fixedly installed on the upper end of the first conveying cylinder 67, a first rotating shaft 610 is fixedly installed on the output end of the first motor 69, and a first conveying auger 611 is fixedly connected to the outer wall of the first rotating shaft 610. A second motor 618 is fixedly installed at the upper end of the second conveying cylinder 615. A second rotating shaft 619 is fixedly installed at the output end of the second motor 618. A second conveying auger 620 is fixedly connected to the outer wall of the second rotating shaft 619. A sand injection pipe 68 is connected to the side of the first conveying cylinder 67. A receiving pipe 617 and a delivery pipe 616 are respectively connected to the upper and lower sides of the second conveying cylinder 615. The sand injection pipe 68 is inserted into the inside of the receiving pipe 617. The inside of the sand settling tank 2 and the sand washing tank 61 are both filled with coarse sand.

[0026] With the above setup, coarse sand is filled in the sedimentation tank 2, forming a process adsorption system that can filter and adsorb fine impurities in the sewage onto the coarse sand, completing the initial purification process of the water. Compared with traditional filter screens and filter membranes, rubber is more cost-effective, and the subsequent maintenance cost is also lower.

[0027] In this method, two sets of sand washing rollers 613 are rotatably installed inside the sand washing trough 61, and an external motor 612 is fixedly installed on the outer wall of the sand washing trough 61. The output end of the external motor 612 rotates through to the inside of the sand washing trough 61 and is connected to the shaft coupling of the sand washing rollers 613.

[0028] With the above-mentioned setup, starting the external motor 612 can drive the inner sand-washing roller 613 to rotate, and simultaneously inject cleaning water into the sand-washing tank 61, thereby cleaning the adhering substances on the surface of the coarse sand.

[0029] In this method, a mounting plate 66 is fixedly connected between the first conveying cylinder 67 and the upper side of the sand washing tank 61, and a vertical plate 614 is fixedly connected between the second conveying cylinder 615 and the side wall of the sewage treatment tank 1.

[0030] In this method, a bottom support 62 is fixedly connected to the bottom of the sand dredging trough 61, a mesh plate 65 is fixedly installed at the upper port of the bottom support 62, a drain outlet 63 is connected to the lower side of the bottom support 62, a first solenoid valve 64 is fixedly installed on the drain outlet 63, and a second solenoid valve 621 is fixedly installed on the delivery pipe 616.

[0031] With the above configuration, when the second conveying cylinder 615 feeds material upwards, the second solenoid valve 621 remains open, allowing the material fed to the upper side of the second conveying cylinder 615 to be discharged from the feeding pipe 616 and fall into the sand washing trough 61. When the first conveying cylinder 67 feeds coarse sand into the receiving pipe 617 through the sand injection pipe 68, the second solenoid valve 621 remains closed, keeping the feeding pipe 616 closed to prevent the coarse sand from falling from the feeding pipe 616 when the second conveying cylinder 615 feeds coarse sand downwards. Impurities in the washed coarse sand fall into the bottom tray 62, which contains wastewater containing dirt. The mesh plate 65 at the upper end of the bottom tray 62 is used to prevent coarse sand from falling into the bottom tray. After the sand washing is completed, the first solenoid valve 64 is opened to discharge the wastewater in the bottom tray 62.

[0032] In this method, an inlet pipe 4 and an outlet pipe 5 are respectively connected and installed on both sides of the sewage treatment tank 1. A fine hole 21 is opened on the side wall of the sedimentation tank 2. A sleeve 22 is fixedly connected to the upper side of the sedimentation tank 2. The sleeve 22 is screwed onto the upper side of the sewage treatment tank 1. A control switch 3 is fixedly installed on the side wall of the sewage treatment tank 1.

[0033] By setting it in the above manner, control switch 3 is used to control the working status of each electrical component.

[0034] The working principle of the modular combined wastewater treatment integrated device provided by this utility model is as follows:

[0035] During operation, wastewater flows into the settling tank 2 within the wastewater treatment tank 1 through the inlet pipe 4. Because the settling tank 2 has fine holes 21 on its sidewalls and is filled with coarse sand, fine impurities in the wastewater are filtered and adsorbed by the coarse sand as it flows through, thus completing the initial purification treatment of the wastewater. When the coarse sand in the settling tank 2 has absorbed a large amount of dirt and needs cleaning, the second motor 618 is started to drive the second conveying auger 620 to rotate in the second conveying cylinder 615, conveying the coarse sand in the settling tank 2 into the sand washing tank 61. The external motor 612 is then started. The output end of the external motor 612 is connected to the sand washing rollers 613 via a coupling, driving the two sets of sand washing rollers 613 to rotate within the sand washing tank 61. Simultaneously, cleaning water is injected into the sand washing tank 61. The rotation of the sand washing roller 613, in conjunction with the cleaning water, effectively removes the adhering substances from the surface of the coarse sand. After cleaning, the first motor 69 is started, which drives the first rotating shaft 610 to rotate. This causes the first conveying auger 611 on the outer wall of the first rotating shaft 610 to rotate inside the first conveying cylinder 67, conveying the coarse sand in the sand washing tank 61 through the sand injection pipe 68 to the receiving pipe 617 of the second conveying cylinder 615. Then, the second motor 618 drives the second conveying auger 620 to reverse, conveying the coarse sand injected into the first conveying cylinder from the upper side of the second conveying cylinder into the sand settling tank. This completes the cleaning and replacement of the coarse sand in the sand settling tank, maintaining a good filtration and adsorption effect for the coarse sand in the sand settling tank and improving the purification efficiency of wastewater.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
