Description

Technical Field

[0001] The utility model relates to the technical field of building water supply and drainage, and particularly to a water-saving building water supply and drainage device. Background Technique

[0002] The water supply and drainage system is a general term for facilities that provide water supply and wastewater drainage for people's living, production, municipal administration, and fire protection. With energy conservation and environmental protection becoming the mainstream of the current era's development, applying the concept of energy conservation and environmental protection to the building water supply and drainage system has also become an important part of the current construction of the water supply and drainage system. Therefore, in the current water supply and drainage system, most of the wastewater is filtered through a filter screen to remove impurities, and then the wastewater is recycled.

[0003] The Chinese patent "A water-saving building water supply and drainage device" with the authorization announcement number "CN 220620402U" uses a filter screen to filter the garbage in the water flow. Under the action of the water flow impact, the garbage on the filter screen is impacted, so that the garbage flows to the other side, and the cleaning plate and the brush reciprocate to clean the remaining garbage on the filter screen, thus avoiding the phenomenon that the garbage not washed away by the water flow adheres to the filter screen, resulting in the blockage of the filter screen, so that the filter screen can efficiently filter the garbage in the water flow.

[0004] Although the impurities on the filter plate can be cleaned in the above application, during the process of the brush moving for cleaning, the impurities around the mesh holes of the filter plate may enter the mesh holes, causing blockage. And during the cleaning process, the smaller impurities in the mesh holes of the filter plate will be loosened, and under the action of the water flow, some smaller impurities will penetrate through the mesh holes of the filter screen, thus affecting the filtering effect of the wastewater.

[0005] Therefore, a water-saving building water supply and drainage device is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a water-saving building water supply and drainage device to solve the above problems, improving the problem that during the process of the brush moving for cleaning, the impurities around the mesh holes of the filter plate may enter the mesh holes, causing blockage, and during the cleaning process, the smaller impurities in the mesh holes of the filter plate will be loosened, and under the action of the water flow, some smaller impurities will penetrate through the mesh holes of the filter screen, thus affecting the filtering effect of the wastewater.

[0007] The present utility model realizes the above object through the following technical solutions. A water-saving building water supply and drainage device includes: a water pipe and a treatment tank. Both ends of the treatment tank are communicated with the water pipe. A collection tank is arranged on one side of the treatment tank, and a treatment mechanism is arranged inside the treatment tank. Among them, the treatment mechanism includes a filter plate fixedly connected to the inner wall of the treatment tank. Equal-column distributed fixing plates are embedded and installed on the inner wall of the filter plate. Equal-column distributed filter frames are fixedly connected to the top of the filter plate. Equal-column distributed through holes are formed on the surface of the filter frame. A moving plate is slidably connected to the upper end of the inner wall of the treatment tank. Equal-column distributed cleaning brushes are fixedly connected to the bottom end of the moving plate. A motor is fixedly connected to the other side of the treatment tank. A reciprocating lead screw is rotatably connected to the inner wall of the treatment tank. One end of the reciprocating lead screw penetrates the treatment tank and is fixedly connected to the output shaft of the motor. A spring telescopic rod is arranged on the surface of the reciprocating lead screw. The bottom end of the spring telescopic rod is fixedly connected to the top end of the moving plate.

[0008] Preferably, the treatment mechanism further includes a leakage frame slidably connected to the lower end of the inner wall of the treatment tank. A brush is fixedly connected to the top end of the leakage frame. Connecting rods are fixedly connected to both ends of the moving plate. The other ends of the two connecting rods are respectively fixedly connected to both ends of the leakage frame. The top end of the brush is attached to the bottom end of the filter plate. Using the brush to clean the filter plate from below the filter plate is beneficial to discharging the impurities in the filter holes of the filter plate to above the filter plate, and flowing to the collection tank through the inclined surface of the filter plate. Under the action of the leakage frame, it is beneficial to intercept the smaller impurities discharged during cleaning, thereby ensuring the filtering effect of the wastewater.

[0009] Preferably, a trigger block is fixedly connected to the inner wall of the treatment tank. A spherical ball is fixedly connected to one side of the spring telescopic rod. Under the interaction of the spherical ball and the trigger block, it is beneficial to make a certain distance between the bottom end of the cleaning brush and the fixing plate, so as to facilitate the better discharge of the impurities on the other side of the cleaning brush through the water flow, and avoid the accumulation of impurities on the other side of the cleaning brush.

[0010] Preferably, an isosceles trapezoid is formed between the vertical section of the filter frame and the horizontal plane. The diameter of the through hole is larger than the diameter of the filter hole of the filter plate. It is beneficial to make the intercepted larger impurities slide down to the fixing plate better.

[0011] Preferably, an included angle is formed between the bottom end of the leakage frame and the horizontal plane. It is beneficial to make the impurities in the leakage frame gather at the lower part of the inner bottom wall of the leakage frame, ensuring the normal drainage operation of the leakage frame.

[0012] Preferably, a protective ring is fixedly connected to the upper end of the inner wall of the treatment tank. The reciprocating lead screw is arranged inside the protective ring. It is beneficial to protect the reciprocating lead screw.

[0013] Preferably, two guiding plates are fixedly connected to the inner wall of the treatment box, and the guiding plates are inclined to prevent impurities from entering the chute.

[0014] Preferably, a chute matching the connecting rod is formed in the inner wall of the treatment box to ensure the stability of the connecting rod during movement.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. When filtering the wastewater, the larger impurities in the wastewater are intercepted by the filter frame and the through holes. Under the action of the inclined surface of the filter frame, it is beneficial for the larger impurities to slide down the inclined surface to the fixed plate, preventing the impurities from staying around the through holes, which is beneficial for the cleaning brush to better clean the impurities and avoid blockage of the through holes when the cleaning brush cleans the impurities. At the same time, the filter plate is cleaned from below by the brush, which is beneficial for the impurities in the filter holes of the filter plate to be discharged above the filter plate and flow into the collection box through the inclined surface of the filter plate. Under the action of the leakage frame, it is beneficial to intercept the smaller impurities discharged during cleaning, thus ensuring the filtering effect of the wastewater.

When the cleaning brush moves above the higher end of the filter plate, under the interaction of the spherical ball and the trigger block, it is beneficial for the bottom end of the cleaning brush to have a certain distance from the fixed plate, so that the impurities on the other side of the cleaning brush can be better discharged through the water flow, preventing the impurities from accumulating on the other side of the cleaning brush.

Detailed implementation mode

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] During specific implementation: As Figures 1-5 shown, the water-saving building water supply and drainage device includes: a water pipe 1 and a treatment tank 2. Both ends of the treatment tank 2 are communicated with the water pipe 1. A collection tank 4 is arranged on one side of the treatment tank 2, and a treatment mechanism 3 is arranged inside the treatment tank 2; wherein, the treatment mechanism 3 includes a filter plate 31 fixedly connected to the inner wall of the treatment tank 2. Fixed plates 32 distributed in equal columns are embedded in the inner wall of the filter plate 31. Filter frames 33 distributed in equal columns are fixedly connected to the top end of the filter plate 31. Through holes 34 distributed in equal columns are formed on the surface of the filter frames 33. A moving plate 35 is slidably connected to the upper end of the inner wall of the treatment tank 2. Cleaning brushes 36 distributed in equal columns are fixedly connected to the bottom end of the moving plate 35. A motor 37 is fixedly connected to the other side of the treatment tank 2. A reciprocating lead screw 38 is rotatably connected to the inner wall of the treatment tank 2. One end of the reciprocating lead screw 38 penetrates through the treatment tank 2 and is fixedly connected to the output shaft of the motor 37. A spring telescopic rod 39 is arranged on the surface of the reciprocating lead screw 38. The bottom end of the spring telescopic rod 39 is fixedly connected to the top end of the moving plate 35.

[0026] The spring telescopic rod 39 ensures a fixed rod, a moving rod and a spring. The surface of the moving rod is slidably connected to the inner wall of the fixed rod. The spring is installed between the top end of the moving rod and the inner top wall of the fixed rod. The collection tank 4 is the same as in the original solution.

[0027] When filtering and treating wastewater, water flows into the treatment tank 2 from the top end of the treatment tank 2 through the water pipe 1. At this time, the filter frames 33 and the through holes 34 filter larger impurities in the water flow, so that the larger impurities will stay on the filter frames 33. The water flow discharged from the through holes 34 is secondarily filtered through the filter plate 31, and smaller impurities will stay on the filter plate 31. During cleaning, the motor 37 is started through the controller to drive the reciprocating lead screw 38 to rotate, so that the spring telescopic rod 39 drives the moving plate 35 to move reciprocally, thereby driving the cleaning brushes 36 to move reciprocally to clean the larger impurities above the fixed plates 32.

[0028] The reciprocating lead screw is in the form of two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating lead screw, the side of the spiral groove pushes the slider placed in the spiral groove to make an axial reciprocating motion.

[0029] AsFigure 3 , Figure 4 and Figure 5 As shown in Figure 4 , Figure 5 , the processing mechanism 3 further includes a leakage frame 311 slidably connected to the lower end of the inner wall of the processing box 2. A brush 312 is fixedly connected to the top end of the leakage frame 311. Connecting rods 313 are fixedly connected to both ends of the moving plate 35. The other ends of the two connecting rods 313 are respectively fixedly connected to both ends of the leakage frame 311. The top end of the brush 312 is in contact with the bottom end of the filter plate 31.

[0030] When the moving plate 35 moves, the leakage frame 311 will be driven to move synchronously under the action of the connecting rod 313, thereby driving the brush 312 to move to clean the filter plate 31 from the bottom end of the filter plate 31, avoiding smaller impurities from clogging the filter holes of the filter plate 31. During the cleaning process, some smaller impurities will enter the leakage frame 311 under the action of the water flow, and under the action of the flowing water, the impurities will remain in the leakage frame 311, and the filtered water is discharged. The diameter of the leakage holes at the bottom end of the leakage frame 311 is smaller than the diameter of the filter holes of the filter plate 31.

[0031] As Figure 3 and Figure 5 shown in Figure 3 and Figure 5 , a trigger block 314 is fixedly connected to the inner wall of the processing box 2, and a spherical ball 315 is fixedly connected to one side of the spring telescopic rod 39. The trigger block 314 is in the shape of a semi-sphere, and the diameter of the spherical ball 315 is larger than the diameter of the trigger block 314. In the initial state of the device, the lower end surface of the spherical ball 315 abuts against the upper end surface of the trigger block 314, causing a gap to be formed between the bottom end of the cleaning brush 36 driven by the moving plate 35 and the fixed plate 32.

[0032] When driving the moving plate 35 to move, the contact between the spherical ball 315 and the trigger block 314 will be released. At this time, under the action of the spring telescopic rod 39, the bottom end of the cleaning brush 36 is always in contact with the fixed plate 32.

[0033] When the spring telescopic rod 39 drives the cleaning brush 36 to reset and move above the higher end of the filter plate 31, the trigger block 314 will abut against the spherical ball 315 again, thereby driving a gap to be formed again between the bottom end of the cleaning brush 36 and the fixed plate 32. At this time, the impurities on the other side of the cleaning brush 36 will flow downward under the action of the water flow.

[0034] As Figure 3 and Figure 4 shown in Figure 3 and Figure 4 , an isosceles trapezoid is formed between the vertical section of the filter frame 33 and the horizontal plane, and the diameter of the through hole 34 is larger than the diameter of the filter holes of the filter plate 31. The fixed plate 32 is installed between two adjacent filter frames 33. When the filter frames 33 and the through holes 34 filter larger impurities in the water flow, the larger impurities will remain on the filter frames 33 and slide down to the fixed plate 32 through the inclined surfaces of the filter frames 33, avoiding the accumulation of impurities on the through holes 34.

[0035] AsFigure 5 As shown, an angle is formed between the bottom end of the leakage frame 311 and the horizontal plane. During the cleaning process of the brush 312, when smaller impurities enter the leakage frame 311, under the action of the inclined surface at the bottom end of the leakage frame 311 and the water flow, the impurities will gather at the lower end of the inner bottom wall of the leakage frame 311.

[0036] As Figure 3 shown, a protective ring 316 is fixedly connected to the upper end of the inner wall of the treatment tank 2, and the reciprocating lead screw 38 is arranged inside the protective ring 316. A moving groove matching the spring telescopic rod 39 is opened at the lower end of the surface of the protective ring 316.

[0037] As Figure 2 shown, two guiding plates 317 are fixedly connected to the inner wall of the treatment tank 2, and the guiding plates 317 are inclined. The guiding plates 317 are arranged above the sliding groove 310. When the water flow enters the treatment tank 2, the guiding plates 317 are used to guide the water flow towards the middle of the filter plate 31.

[0038] As Figure 2 shown, a sliding groove 310 matching the connecting rod 313 is opened on the inner wall of the treatment tank 2. The shape of the sliding groove 310 is "U", and the sliding groove 310 is inclined and has the same movement path as the moving plate 35.

[0039] When the utility model is in use and filtering and treating wastewater, the water flow enters the treatment tank 2 from the top end of the treatment tank 2 through the water pipe 1. The filter frame 33 and the through hole 34 filter larger impurities in the water flow, so that the larger impurities slide down to the fixed plate 32 through the inclined surface of the filter frame 33, avoiding the accumulation of impurities on the through hole 34. At the same time, the water flow discharged from the through hole 34 is secondarily filtered through the filter plate 31, and smaller impurities will remain on the filter plate 31. When cleaning, the motor 37 is started to drive the reciprocating lead screw 38 to rotate, so that the spring telescopic rod 39 drives the moving plate 35 to reciprocate, thereby driving the cleaning brush 36 to reciprocate to clean the larger impurities above the fixed plate 32. When the cleaning brush 36 moves to one side of the collection box 4, the impurities cleaned by the cleaning brush 36 will enter the collection box 4. At the same time, under the action of the connecting rod 313, the moving plate 35 will drive the leakage frame 311 to move synchronously, thereby driving the brush 312 to move to clean the filter plate 31 from the bottom end of the filter plate 31. During the cleaning process, some smaller impurities will enter the leakage frame 311 under the action of the water flow, and under the action of the water flow, the impurities will remain in the leakage frame 311, and the filtered water is discharged.

[0040] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
