Description

Technical Field

[0001] The utility model belongs to the technical field related to water supply pipe networks, and specifically relates to a filtering and sewage discharge device used in water supply pipe networks. Background Art

[0002] The water supply network is a part of the urban tap water network. It is the source of water supply to the water plant. The source water is pumped to the water plant for filtration, sedimentation and other treatments, and the clean tap water is delivered to urban residents. In the process of extracting source water from the water supply network, the source water needs to be filtered and discharged to prevent garbage and impurities in the source water from clogging the water supply pipes and increasing the staff's attention on tap water.

[0003] The existing filtering and sewage discharge device for water supply network has the following disadvantages during use:

[0004] On the one hand, only a single filter structure is set in the water supply network structure to intercept dirt. However, when the filter needs to be replaced, the water valve needs to be manually closed to stop the water supply before the filter structure can be replaced, which affects the use of residents during the replacement.

[0005] Secondly, when replacing the filter, a bolt structure is generally used for fixing or loosening. However, since the environment in which the water supply network structure is located is generally humid, the bolts are prone to rust, which can easily cause great inconvenience when disassembling and replacing the filter structure. For this reason, we propose a filtering and sewage discharge device for a water supply network. Utility Model Content

[0006] The purpose of the utility model is to provide a filtering and sewage discharge device for a water supply network to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering and sewage discharge device for a water supply network, comprising a filter box, a water inlet at the left edge of the top end of the filter box is fixedly connected to a water inlet pipe, a water outlet at the left edge of the bottom end of the filter box is fixedly connected to a water outlet pipe, a rotating plate is movably installed on the inner wall of the filter box, the top end of the rotating plate is connected to the filter box through a rotating dividing structure, two symmetrically arranged insertion channels are provided on the rotating plate, and filter screens with I-shaped structures in vertical cross-section are movably inserted in the insertion channels, the rotating dividing structure can realize the rotation of the rotating plate, and realize the position exchange of the two filter screens, and a large partition is fixedly connected to the middle of the bottom end of the rotating plate;

[0008] An inspection port is provided on the right side wall of the filter box, in which a sealing plate with a convex vertical cross-section is movably installed. A convenient clamping structure is connected between the top of the sealing plate and the outside of the filter box. The convenient clamping structure facilitates clamping and fixing of the sealing plate, thereby facilitating removal and replacement of the filter screen close to the sealing plate.

[0009] As a preferred embodiment, the rotating shifting structure includes a rotating cylinder fixed at the top center of the rotating plate, small partitions are fixed on the front and rear sides of the rotating cylinder, and a motor is fixed at the top center of the filter box on a side wall away from the two small partitions. The output shaft of the motor passes through the filter box and is fixed to the top center of the rotating cylinder.

[0010] As a preferred embodiment, magnetic plates are fixedly connected to the opposite side walls of the two filter screens, and magnetic slots matching the magnetic plates are opened in the inner walls of the two insertion channels, and the magnetic plates and the magnetic slots are magnetically attracted to each other.

[0011] As a preferred embodiment, the convenient clamping structure includes two symmetrically arranged positioning holes on the top of the sealing plate, positioning columns are inserted in the positioning holes, and the tops of the two positioning columns are fixedly connected to the same arc-shaped synchronization rod, which is slidably connected to the outside of the filter box through a slider with a convex cross-section.

[0012] As a preferred embodiment, the slider is slidably connected to a slide groove provided on the outside of the filter box, and the top end of the slider is connected to the inner top wall of the slide groove through a spring.

[0013] As a preferred implementation, the depth of the positioning hole is smaller than the thickness of the arc-shaped synchronization rod.

[0014] Compared with the prior art, the filtering and sewage discharge device for a water supply network provided by the utility model has at least the following beneficial effects:

[0015] (1) By setting the rotating gear structure, after starting the motor, the rotating drum drives the rotating plate and the two small partitions and the large partition to rotate 180 degrees, thereby driving the positions of the two filter screens to be swapped. When the left filter screen needs to be replaced, the right filter screen can be replaced in time, so that the filter screen can be replaced without closing the valve, thereby avoiding the problem of affecting the water use of residents;

[0016] (2) By setting up a convenient clamping structure, when the nearby filter needs to be replaced, the arc-shaped synchronization rod can be manually lifted up, so that the two positioning columns are disengaged from the positioning holes set at the top of the sealing plate, and the slider presses the spring. After that, the sealing plate can be taken out from the inspection port, so that the corresponding nearby filter can be pulled out from the insertion channel, and then the filter can be replaced, which is very convenient.

[0024] Example

[0025] On the one hand, only a single filter structure is provided in the water supply network structure to intercept dirt. However, when the filter 51 needs to be replaced, the water valve needs to be manually closed to stop the water supply before the filter structure can be replaced, which affects the use of the residents during the replacement.

[0026] Secondly, when the filter screen 51 is replaced, a bolt structure is generally used for fixing or loosening. However, since the environment in which the water supply network structure is located is generally humid, the bolts are prone to rust, which can easily cause great inconvenience when disassembling and replacing the filter structure.

[0027] To do this, see Figure 1-3 The utility model provides a filtering and sewage discharge device for a water supply network, comprising: a filter box 1, a water inlet at the left edge of the top of the filter box 1 is fixedly connected to a water inlet pipe 2, a water outlet at the left edge of the bottom of the filter box 1 is fixedly connected to a water outlet pipe 3, a rotating plate 5 is movably installed on the inner wall of the filter box 1, the top of the rotating plate 5 is connected to the filter box 1 through a rotating dividing structure 4, two symmetrically arranged insertion channels are provided on the rotating plate 5, and filter screens 51 with I-shaped structures in vertical cross-section are movably inserted in the insertion channels, the rotating dividing structure 4 can realize the rotation of the rotating plate 5, and realize the position exchange of the two filter screens 51, and a large partition plate 53 is fixedly connected to the middle part of the bottom end of the rotating plate 5;

[0028] An inspection port is provided on the right side wall of the filter box 1, in which a sealing plate 61 with a convex structure in vertical cross section is movably installed, and a convenient clamping structure 6 is connected between the top of the sealing plate 61 and the outer side of the filter box 1. The convenient clamping structure 6 is convenient for clamping and fixing the sealing plate 61, so as to facilitate the removal and replacement of the filter screen 51 close to the sealing plate 61.

[0029] Among them, the large partition 53 can divide the area below the rotating plate 5, that is, the inner side of the filter box 1, into two chambers, so that when water enters the water inlet pipe 2, it is filtered through the filter screen 51 and discharged from the water outlet pipe 3, and when replacing the filter screen 51 on the right side, it is not easily obstructed by the flowing water.

[0030] Further as Figure 1-3 As shown, it is worth explaining in detail that in order to be able to swap the positions of the two filter screens 51, a rotating shifting structure 4 is provided, including a rotating cylinder 42 fixed at the top center of the rotating plate 5, and small partitions 43 are fixed on the front and rear sides of the rotating cylinder 42. On a side wall away from the two small partitions 43, a motor 41 is fixed at the top center of the filter box 1, and the output shaft of the motor 41 passes through the filter box 1 and is fixed to the top center of the rotating cylinder 42. Magnetic plates 52 are fixed on the side walls opposite to each other of the two filter screens 51, and magnetic slots matching the magnetic plates 52 are provided in the inner walls of the two insertion channels, and the magnetic plates 52 and the magnetic slots are magnetically attracted to each other.

[0031] The length of the filter screen 51 is smaller than the length of the sealing plate 61 .

[0032] Further as Figure 1-3 As shown, it is worth explaining in detail that, in order to facilitate the disassembly and assembly of the sealing plate 61 and the quick disassembly and assembly of the filter screen 51, a convenient clamping structure 6 is provided, including two symmetrically arranged positioning holes provided at the top of the sealing plate 61, and positioning columns 62 are inserted in the positioning holes. The top ends of the two positioning columns 62 are fixedly connected with the same arc-shaped synchronization rod 63, and the arc-shaped synchronization rod 63 is slidably connected to the outside of the filter box 1 through a slider 64 with a convex cross-section. The slider 64 is slidably connected to a slide groove provided on the outside of the filter box 1, and the top end of the slider 64 is connected to the inner top wall of the slide groove through a spring 65. The depth of the positioning hole is smaller than the thickness of the arc-shaped synchronization rod 63.

[0033] Manually lifting the arc-shaped synchronization rod 63 causes the two positioning posts 62 to come out of the positioning holes. At this time, the sealing plate 61 is not restricted by clamping, so that the sealing plate 61 can be drawn out from the inspection port, thereby facilitating replacement of the filter screen 51.

[0034] In summary: when using the filtering and draining device for the water supply network, when the filter screen 51 on the left side needs to be replaced, the motor 41 is started, so that the rotating cylinder 42 drives the rotating plate 5 and the two small partitions 43 and the large partition 53 to rotate one hundred and eighty degrees, thereby driving the positions of the two filter screens 51 to be swapped, so that when the filter screen 51 on the left side needs to be replaced, the filter screen 51 on the right side can be replaced in time, so that the filter screen 51 can be replaced without closing the valve, thereby avoiding the problem of affecting the water use of the residents. Secondly, by manually lifting the arc-shaped synchronization rod 63, the two positioning columns 62 are disengaged from the positioning holes. At this time, the sealing plate 61 is not restricted by the clamping, so that the sealing plate 61 can be pulled out from the inspection port, thereby facilitating the replacement of the filter screen 51.
