Description

Technical Field

[0001] The invention relates to the technical field of building water supply and drainage, and in particular to a combined sewage discharge device suitable for building water supply and drainage. Background Art

[0002] The building water supply and drainage system is a key infrastructure to ensure the normal operation of building functions. The performance of sewage discharge devices directly affects environmental sanitation, pipeline maintenance costs and system stability. Traditional sewage discharge devices usually adopt a single device (such as floor drains, drain pipes, inspection wells, etc.) to operate independently, which has many limitations. It only has preliminary drainage functions and lacks filtering devices. Hair, debris, etc. can easily enter the pipes and cause blockages; although some floor drains are equipped with filters, they are cleaned frequently and the sealing is insufficient, resulting in odor. They are mainly used for pipeline connection and maintenance, and some only have simple sedimentation tanks. The treatment effect on grease, suspended solids, etc. in sewage is poor, and regular dredging is required. The labor cost is high. For example, grease separators, septic tanks, etc., although they can achieve some treatment functions, the equipment is independently set up, occupying a large area, the pipeline connection is complex, and it is difficult to coordinate efficiently with the building drainage system.

[0003] In conjunction with the above content, it should be noted that: Chinese patent application number CN2022108207584 discloses a water-saving building water supply and drainage device and drainage method, which uses a pressing block to squeeze the wastewater in the filtered debris, so that the wastewater in the debris is discharged, which is convenient for puncturing sealed containers such as plastic bags or plastic bottles in the debris. The debris accumulated after squeezing is automatically discharged and reset by the debris discharge mechanism, ensuring the reliable, stable and continuous operation of the water supply and drainage system;

[0004] In fact, the above-mentioned device can effectively filter out drainage impurities through the one-way reciprocating extrusion structure, but the overall device structure has limitations, resulting in a certain amount of operating interval time during a single drainage impurity treatment, thereby affecting the drainage treatment efficiency under large load conditions.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a combined sewage discharge device suitable for building water supply and drainage, including a combined rotary filter frame 1, a cartridge frame 7 is provided in the center of the combined rotary filter frame 1, and a plurality of groups of extrusion plates 704 are arranged in a circular array on the outer peripheral wall of the cartridge frame 7. An extrusion slag discharge frame 3 that cooperates with the cartridge frame 7 is provided on the top of one end of the combined rotary filter frame 1, a pressing plate 305 is provided in a sliding sleeve inside the extrusion slag discharge frame 3, and a slide plate 303 extending to the interior of the combined rotary filter frame 1 is provided on the side of the extrusion slag discharge frame 3.

[0034] Sewage flows in along the semicircular groove in the middle of the buffer unloading plate 6. After the sewage is collected inside the combined rotary filter frame 1, it is first filtered by the main filter frame 207, intercepting impurities in the sewage and retaining them at the bottom of the combined rotary filter frame 1. The sewage is connected to the drain port 201 along the main discharge port 102 and guided to flow into the next stage.

[0035] One end of the combined rotary filter rack 1 is provided with several groups of spliced sealing plates 101, the bottom of the sealing plate 101 is provided with a main discharge port 102 and a side discharge port 103, and a detachable special-shaped grid is provided inside the side discharge port 103. The top two ends of the combined rotary filter rack 1 are symmetrically provided with frame columns 104 that are connected to the cartridge rack 7.

[0036] A driving motor 701 is sleeved inside the cartridge rack 7, and a rotating sleeve 702 connected to the driving motor 701 is sleeved on the outer peripheral wall of the cartridge rack 7. The outer peripheral wall of the rotating sleeve 702 is fixedly connected to a plurality of extrusion plates 704. A plurality of groups of holes are provided on the plate body of the extrusion plate 704 close to the rotating sleeve 702, and a driven ring frame 703 sleeved with the combined rotary filter rack 1 is provided on the plate body of the extrusion plate 704 away from the rotating sleeve 702.

[0037] During the period when the combined rotary filter frame 1 continuously filters and intercepts sewage, the driving motor 701 drives the rotating sleeve 702 to rotate along the outer periphery of the cartridge frame 7. The driving motor 701 and the rotating sleeve 702 are connected by couplings, reduction gears and other accessories. The rotating sleeve 702 drives the extrusion plate 704 to perform circular rotational motion between the outer periphery of the cartridge frame 7 and the interior of the combined rotary filter frame 1. The driven ring frame 703 slides along the inner wall of the combined rotary filter frame 1 to maintain the rotational stability of the extrusion plate 704. An auxiliary motor connected to the driven ring frame 703 can be provided on the inner wall of the combined rotary filter frame 1 to cooperate with the rotation of the extrusion plate 704.

[0038] The squeezing plates 704 collect and carry the impurities accumulated inside the combined rotary filter frame 1 by rotating. When the squeezing plates 704 approach the frame column 104, the sewage in the impurities is collected in the hole area under the traction of its own weight and gravity, and flows back to the bottom of the combined rotary filter frame 1 along the hole. When this group of squeezing plates 704 approaches the frame column 104 and the previous group passes the frame column 104, the partially propelled hydraulic arm 301 drives the slide plate 303 to move along the inside of the sliding sleeve 302 toward the inside of the combined rotary filter frame 1 and is stuck between the corresponding frame columns 104, so that the area between the approaching squeezing plates 704 and the slide plate 303 is blocked, forming a temporary squeezing cavity. As the squeezing plates 704 continue to approach, the temporary squeezing cavity is continuously reduced, and the impurities between the squeezing plates 704 and the slide plate 303 are continuously compressed, so that the sewage in the impurities is squeezed out, part of the sewage is discharged along the hole, and part of the sewage enters the bottom of the squeezing slag discharge frame 3 and is discharged along the leakage groove 304.

[0039] After the extrusion plate 704 and the slide plate 303 have completed the initial extrusion of the impurities, the extrusion plate 704 returns to its original position and rotates a certain distance, so that the temporary extrusion cavity can accommodate the pressing plate 305. The pressing plate 305 is separated from the sliding cavity under the coordinated operation of several groups of propulsion hydraulic arms 301, and the impurities between the extrusion plate 704 and the slide plate 303 are squeezed for the second time until the impurities adhere to the inner wall of the fan plate 502, and the squeezed sewage is discharged outward along the hole.

[0040] A sliding cavity is provided on one end of the extrusion slag discharge frame 3 facing the combined rotary filter frame 1, and a pressing plate 305 is slidably sleeved inside the sliding cavity. A sliding sleeve 302 is provided on the outer wall of one side of the extrusion slag discharge frame 3, and a plurality of groups of propulsion hydraulic arms 301 are provided on the outer walls on both sides of the extrusion slag discharge frame 3, which are respectively connected to the pressing plate 305 and the slide 303. A leakage groove 304 is provided at the bottom of the extrusion slag discharge frame 3.

[0041] After waiting for the secondary pressurization to be completed, the pressing plate 305 resets and withdraws a distance, and the servo motor 503 drives the fan plate 502 to rotate through the coupling and gears. The fan plate 502 is stored in the groove at the bottom of the slag discharge port 501, so that the dehydrated impurities are exposed in the slag discharge port 501, and the hydraulic arm 301 is pushed to further drive the pressing plate 305 to move toward the slag discharge port 501, pushing the impurities into the slag discharge port 501. The extraction frame outside the slag discharge port 501 is provided with a transportation device for centralized transportation of the dehydrated impurities. During the continuous use of the combined rotary filter frame 1, the air filter continues to operate to extract the air at the top of the combined rotary filter frame 1 and continuously purify it.

[0042] Embodiment 2: This embodiment is a combined sewage discharge device suitable for building water supply and drainage, including a combined rotary filter frame 1 with a diverter partition frame 2 connected to an extrusion slag discharge frame 3 at the bottom of one end, an air purifier 4 arranged side by side with the extrusion slag discharge frame 3 on the top side of the diverter partition frame 2, a flow-blocking wall panel 206 and a main filter frame 207 are sleeved side by side on one side of the bottom of the diverter partition frame 2, a buffer unloading plate 6 is arranged at the bottom of the other end of the combined rotary filter frame 1, and a sealing cover 5 is arranged on the top of the buffer unloading plate 6.

[0043] The center of the bottom of the diversion partition frame 2 is provided with a drain port 1 201, and a drain port 2 202 is provided side by side on the side of the drain port 1 201. A lifting special-shaped plate 203 is provided on the top of the drain port 202. After the main filter frame 207 has been running for a certain period of time, the lifting special-shaped plate 203 is opened to keep the side discharge port 103 connected with the drain port 2 202, and the traction slide 205 drives the flow blocking wall plate 206 to approach the drain port 1 201, blocking the drain port 1 201, and at the same time pulling the main filter frame 207 away. The discharge outlet 201 is convenient for inspecting, maintaining or replacing the main filter frame 207. The main filter frame 207 will be reset after the replacement is completed. It should be noted that under normal circumstances, the side outlet 103 remains closed, and impurities are pulled into the main outlet 102 by sewage, reducing the damage to the detachable special-shaped grid in the side outlet 103. When the side outlet 103 is open, the pressure affects the silt and other small impurities attached to the surface of the detachable special-shaped grid, thereby ensuring the service life of the detachable special-shaped grid.

[0044] A middle partition frame 208 is provided in the middle of the side of the drain port 1 201 away from the drain port 2 202. A main filter frame 207 is slidably provided on the end of the middle partition frame 208 close to the combined rotary filter frame 1. A flow blocking wall panel 206 is slidably provided on the end of the middle partition frame 208 away from the combined rotary filter frame 1.

[0045] The bottom of the flow-blocking wall plate 206 and the main filter frame 207 are provided with a matching traction slide 205, and the top of the diversion partition frame 2 is provided with a supporting plate 204.

[0046] The buffer unloading plate 6 is symmetrically provided with several groups of triangular plates at the bottom of one end near the combined rotary filter frame 1. The middle part of the buffer unloading plate 6 is provided with a semicircular groove adapted to the combined rotary filter frame 1. When the sewage from the building water supply and drainage is collected and guided close to the combined discharge device, the sewage first contacts the buffer unloading plate 6. The buffer unloading plate 6 guides the unloading force jointly with the combined rotary filter frame 1 body through the triangular plate. At the same time, the two sides of the buffer unloading plate 6 are wider than the combined rotary filter frame 1, so it can be strengthened with the foundation on which the combined discharge device is installed to ensure the installation stability of the overall combined discharge device.

[0047] A slag discharge port 501 corresponding to the extrusion slag discharge frame 3 is provided on the top of the cover 5 , a fan plate 502 is nested at the bottom of the slag discharge port 501 , and a servo motor 503 connected to the fan plate 502 is provided at the bottom center of the cover 5 .

[0048] Combining Example 1 and Example 2, the present invention realizes multiple advantages from the perspective of structural design and functional integration. The buffer unloading plate 6, the triangular plate and the combined rotary filter frame 1 jointly unload the force, and the wide body design strengthens the foundation connection to ensure stable installation; the main filter frame 207 cooperates with the side discharge port 103 to achieve efficient filtration and convenient maintenance; the drive motor 701 links various components to automatically complete impurity collection and extrusion dehydration; the buffering, filtering, purification and other functions are integrated to suppress odor; the modular structure and self-cleaning design reduce wear and blockage, reduce operation and maintenance costs, and are both efficient and environmentally friendly, in line with the development needs of green buildings.
