Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a sewage interception grille with a modular combination structure. Background Art

[0002] With the continuous improvement of environmental awareness in modern society, environmental protection projects play an increasingly important role in modern society. Among the many environmental protection facilities, sewage interception screens are widely used in the fields of sewage treatment, river management, etc. In the sewage treatment process, sewage often contains various solid debris, such as branches, leaves, plastic bags, etc. If these debris are not intercepted, they are very likely to cause damage to subsequent treatment equipment. The emergence of sewage interception screens effectively solves the above problems. Among them, the Chinese patent with patent publication number CN221637546U discloses an interception device for sewage treatment in a sewage treatment pool. The interception device for sewage treatment in a sewage treatment pool is coordinated with devices such as a frame, a grid rack and a roller, so that the device can easily intercept and clean impurities in sewage, and clean impurities such as plastic bags attached to the tooth rake, so as to avoid the accumulation of impurities affecting the interception effect of the device. However, in the process of intercepting impurities, various tiny debris such as fine particles and fibers can easily get stuck in the pores of the filter screen in the interception device of the above scheme, and as the use time increases, the blockage will become more serious, which will not only greatly reduce the interception efficiency of the interception device, but also affect the operation effect of the entire environmental protection project.

[0003] Therefore, how to provide a sewage interception grille device that can extend the sewage interception operation time and facilitate the cleaning of impurities stuck and blocked in the grille pores has become one of the important technical problems that need to be solved urgently in this field. Utility Model Content

[0004] The technical problem to be solved by this technical solution is how to extend the sewage interception operation time of the sewage interception grille and facilitate the disassembly, cleaning and maintenance of the grille device.

[0005] In order to solve the above technical problems, the technical scheme provides a sewage intercepting grid with a modular combination structure, which comprises an X-shaped frame body, a fixed grid and a movable grid. The X-shaped frame body is mainly composed of a horizontally arranged bottom plate and two vertically arranged side plates. The lower ends of the two side plates are fixedly combined with the two ends of the bottom plate to form a setting space with an upper opening in the X-shaped frame body. The fixed grid is mainly composed of a fixed frame plate, a plurality of vertical rods, an upper extension plate, a lower extension plate and a horizontal moving mechanism. The fixed frame plate is vertically arranged and has a rectangular opening formed in the inside thereof and extending through the two side surfaces thereof. The plurality of vertical rods are vertically arranged and fixedly combined in the rectangular opening at the same interval. The upper and lower extension plates are horizontally arranged and have the same side edges fixedly combined with the upper and lower ends of the fixed frame plate, respectively, so that the upper and lower extension plates are parallel to each other. The horizontal moving mechanism is arranged on the upper extension plate. The fixed grid can be slidably installed in the setting space through the upper opening and tightly abut against the upper surface of the bottom plate and the opposite sides of the two side plates of the fixed frame plate. The movable grid is mainly composed of a movable frame plate, a plurality of horizontal rods and a moving connection part. The movable frame plate is vertically arranged and has a rectangular opening formed in the inside thereof and extending through the two side surfaces thereof, corresponding to the rectangular opening of the fixed frame plate. The plurality of horizontal rods are horizontally arranged and fixedly combined in the rectangular opening at the same interval. The moving connection part is fixedly combined with the upper end of the movable frame plate. The moving connection part is movably installed on the horizontal moving mechanism, so that the rectangular opening and the rectangular opening are aligned, and the movable grid can move horizontally in the moving space formed by the fixed frame plate, the upper extension plate and the lower extension plate. Accordingly, the plurality of vertical rods in the rectangular opening of the fixed grid and the plurality of horizontal rods in the rectangular opening of the movable grid are stacked to form a grid for intercepting impurities in sewage. At the beginning of use of the grid, the fixed grid and the movable grid can be abutted against each other by adjusting the horizontal moving mechanism, so as to reduce the pores formed between the vertical rods and the horizontal rods, thereby improving the interception effect of the impurities. As the use time of the grid increases, various small impurities will be gradually stuck and clogged in the pores of the grid. At this time, the horizontal moving mechanism is adjusted to gradually move the movable grid away from the fixed grid, so that the pores between the vertical rods and the horizontal rods are gradually increased, thereby gradually reducing the adverse effects of the stuck and clogged impurities on the grid to ensure that the grid has a continuously good interception effect of the impurities, thereby prolonging the sewage intercepting operation time of the grid in a way of dynamically adjusting the size of the pores of the grid. When the sewage intercepting grid accumulates a large amount of impurities and needs to be thoroughly cleaned and maintained, the fixed grid together with the movable grid can be taken out from the setting space of the X-shaped frame body, so that the cleaning and maintenance of the grid body (i.e. the fixed grid and the movable grid) can be realized. After the cleaned grid body is reinstalled in the setting space, the grid can be put into operation again. The above convenient installation and removal operation of the grid body can greatly shorten the shutdown and maintenance time of the grid body, thereby improving the overall operation efficiency of the sewage intercepting system.

[0006] As another implementation of the present technical solution, the horizontal moving mechanism is mainly composed of two fixed vertical plates, a lead screw and a rotating disc. A through slot is formed in the middle of the upper extension plate, and the length direction of the through slot is the same as the moving direction of the movable grid. The two fixed vertical plates are vertically fixed to the upper side of the upper extension plate and located at the two ends of the length direction of the through slot. The lead screw is rotatably fixed to the two fixed vertical plates through bearings, and the end of the lead screw away from the moving space is fixed to the central part of the disc surface of the rotating disc. The moving connection part is composed of a moving plate located above and a connecting plate located below. The width of the moving plate is greater than the width of the through slot. The moving plate is screwed onto the lead screw between the two fixed vertical plates through a ball nut pair. The width of the connecting plate is less than the width of the through slot, and the connecting plate is movably arranged in the through slot. The lower end of the connecting plate is fixedly connected to the central part of the upper end of the movable frame plate. The rotating disc drives the lead screw, the moving connection part and the movable frame plate to move horizontally. In this way, the distance between the fixed grid and the movable grid can be adjusted by rotating the rotating disc, so as to dynamically adjust the size of the grid gap.

[0007] As another implementation of the present technical solution, the horizontal moving mechanism further comprises a fixed block and a first screw. The fixed block is fixedly connected to the upper side of the upper extension plate and located beside the disc edge of the rotating disc. A through first screw hole is formed in the fixed block towards the direction of the rotating disc. The first screw hole has an internal thread. The first screw is screwed into the first screw hole. The disc edge is uniformly provided with a plurality of fixing holes along the circumferential direction. The end of the first screw close to the disc edge can be inserted into one of the fixing holes by screwing the first screw, so as to fix the rotating disc. In this way, the size of the grid gap can be indirectly fixed.

[0008] As another implementation of the present technical solution, the upper side of the lower extension plate is recessed to form two sliding grooves on both sides. The lower end of the movable frame plate is fixedly provided with two sliding blocks corresponding to the two sliding grooves. The two sliding blocks are movably embedded in the two sliding grooves. In this way, the position deviation of the movable grid during movement can be prevented by the embedded moving structure of the sliding groove and the sliding block.

[0009] As another implementation of the present technical solution, a recess is formed on the side of the fixed frame plate facing the movable frame plate above the rectangular opening. A protrusion is formed on the movable frame plate corresponding to the recess. When the movable frame plate moves towards the fixed frame plate and is attached, the protrusion is aligned and embedded in the recess. In this way, the stability of the movable frame plate after being attached to the fixed frame plate can be improved.

[0010] As another embodiment of this technical solution, two embedded plates are vertically fixedly connected to each side of the fixed frame. Two embedded grooves are respectively formed on the opposite sides of the two side plates, corresponding to the two embedded plates. The two embedded plates are movably slidably mounted in the two embedded grooves, so that the fixed frame can be removably fixed between the two side plates. Accordingly, the sliding connection between the embedded plates and the embedded grooves not only facilitates the installation and removal of the grille body and the U-shaped frame, but also enhances the horizontal stability of the grille body and the U-shaped frame after being connected.

[0011] As another embodiment of the present technical solution, the sewage intercepting grille further includes: two penetration blocks, two second screws, and two coupling blocks. The two penetration blocks are respectively fixedly coupled to the upper ends of the two side panels, and the two penetration blocks are respectively provided with second screw holes through them facing each other, and the second screw holes have internal threads. The two second screws are respectively screwed into the two second screw holes. The two coupling blocks are fixedly coupled to both sides of the upper end of the fixed frame plate corresponding to the two penetration blocks, and the two coupling blocks are respectively provided with insertion holes corresponding to the two second screw holes. By screwing the two second screws so that the ends close to the two coupling blocks can be inserted into the two insertion holes, the fixed frame plate is fixed. Accordingly, the grille body can be locked in the U-shaped frame, thereby strengthening the vertical stability of the grille body after being coupled to the U-shaped frame.

[0012] The cleaning brush of the present invention is a device for cleaning a cleaning surface of the cleaning surface, the cleaning brush being affixed to the cleaning surface of the cleaning surface and the like, and the cleaning brush being affixed to the cleaning surface of the cleaning surface. Based on this, some impurities stuck and blocked on the movable grille and the fixed grille can be brushed away to extend the operating time of the sewage interception grille.

[0013] As another embodiment of this technical solution, the grille cleaning mechanism further includes: two auxiliary fixing plates and a sliding rod. The two auxiliary fixing plates are respectively fixedly coupled to the outer sides of the upper and lower ends of the other guide slot. The ends of the sliding rod are fixed to the two auxiliary fixing plates. The mounting plate has sliding holes formed at positions corresponding to the sliding rods. The sliding rods are slidably mounted through the sliding holes, allowing the U-shaped plate to be guided by the sliding rods. This improves the stability of the U-shaped plate during its upward and downward movement.

[0014] As another embodiment of this technical solution, the grille cleaning mechanism further includes a drive motor mounted on the upper portion of the fixed plate, with the upper end of the reciprocating screw extending through the fixed plate and connected to the drive end of the drive motor. This improves the automation level of the sewage interception grille. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the present invention.

[0022] In the context of this specification, any two or more embodiments of the present invention can be arbitrarily combined, and the technical solutions thus formed belong to part of the original disclosure of this specification and also fall within the scope of protection of the present invention.

[0023] like Figure 1 、 2 Figures 3 and 4 are schematic diagrams of a specific embodiment of a modular sewage interception screen according to the present invention. This modular sewage interception screen (hereinafter referred to as the sewage interception screen) comprises a U-shaped frame 1, a fixed screen 2, and a movable screen 3. The U-shaped frame 1 is fixedly mounted on the bottom and side walls of a sewage channel, such as a river or ditch. The U-shaped frame 1 primarily comprises a horizontal bottom plate 11, perpendicular to the flow of sewage, and two vertical side plates 12. The lower ends of the two side plates 12 are fixedly coupled to the ends of the bottom plate 11, forming a space with an upper opening within the U-shaped frame 1. The fixed grille 2 is mainly composed of a fixed frame plate 21, a plurality of vertical rods 212, an upper extension plate 22, a lower extension plate 23 and a horizontal moving mechanism 24. The fixed frame plate 21 is vertically arranged and has a rectangular opening 211 running through its two side surfaces. The plurality of vertical rods 212 are vertically arranged and fixedly coupled to the rectangular opening 211 at the same intervals. The upper and lower extension plates 22, 23 are both horizontally arranged and the same side edges of the upper and lower extension plates 22, 23 are respectively fixedly coupled to the upper and lower ends of the fixed frame plate 21 so that the upper and lower extension plates 22, 23 are parallel to each other. The horizontal moving mechanism 24 is arranged on the upper extension plate 22. The fixed grille 2 can be slidably installed in the setting space through the upper opening of the U-shaped frame body 1 and make the lower side of the lower extension plate 23 and the two sides of the fixed frame plate 21 tightly fit with the upper side of the bottom plate 11 and the opposite sides of the two side plates 12. The movable grille 3 is primarily composed of a movable frame 31, a plurality of crossbars 312, and a movable connecting portion 32. The movable frame 31 is vertically arranged and has rectangular openings 311 extending through its two sides, corresponding to the rectangular opening 211. The crossbars 312 are horizontally arranged and fixedly coupled to the rectangular opening 311 at equal intervals. The movable connecting portion 32 is fixedly coupled to the upper end of the movable frame 31. By movably attaching the movable connecting portion 32 to the horizontally movable mechanism 24 of the fixed grille 2, the rectangular opening 211 is aligned with the rectangular opening 311, and the movable grille 3 is able to move horizontally within the movable space enclosed by the fixed frame 21, the upper extension plate 22, and the lower extension plate 23.

[0024] In more detail, combined with Figure 3As shown, the horizontal moving mechanism 24 is mainly composed of two fixed vertical plates 241, a screw rod 242 and a turntable 243. A through slot 221 is provided in the middle of the upper extension plate 22, which runs through both sides thereof. The length direction of the through slot 221 is the same as the moving direction of the movable grille 3. The two fixed vertical plates 241 are vertically fixedly coupled to the upper side of the upper extension plate 22 and are located at both ends of the length direction of the through slot 221. The screw rod 242 is rotatably fixed to the two fixed vertical plates 241 through a bearing (not shown in the figure), and the end of the screw rod 242 away from the moving space passes through the fixed vertical plate 241 and is coupled to the center of the disk surface of the turntable 243. Figure 2 As shown, the movable connecting portion 32 is composed of a movable plate 321 located at the top and a connecting plate 322 located at the bottom, which are fixedly connected to each other. The width of the movable plate 321 is greater than the width of the through slot 221, and the movable plate 321 is sleeved and screwed onto the screw rod 242 located between the two fixed vertical plates 241 through a ball nut pair (not shown in the figure), and the width of the connecting plate 322 is less than the width of the through slot 221, and the connecting plate 322 is movably inserted into the through slot 221, and the lower end of the connecting plate 322 is fixedly connected to the center of the upper end of the movable frame plate 31. By rotating the turntable 243 to drive the screw rod 242 and drive the movable connecting portion 32 and the movable frame plate 31 to move horizontally, the distance between the fixed grille 2 and the movable grille 3 can be adjusted, thereby dynamically adjusting the size of the grille gap. In addition, combined with Figure 3 As shown, the horizontal movement mechanism 24 may further include a fixing block 244 and a first screw 245. The fixing block 244 is fixedly coupled to the upper side of the upper extension plate 22 and is located next to the rim of the rotating disk 243. A first screw hole (not shown) is formed in the fixing block 244, extending toward the rotating disk 243. The first screw hole has an internal thread, and the first screw 245 is screwed into the first screw hole. The rim is uniformly circumferentially defined with a plurality of fixing holes 2431. By tightening the first screw 245 so that the end of the first screw 245 near the rim can be inserted into one of the fixing holes 2431, the rotating disk 243 is fixed, thereby indirectly fixing the size of the grille gap.

[0025] In this embodiment, in order to improve the stability of the movable grille 3 during movement, two sliding grooves 231 can be formed by recessing downward on both sides of the upper side surface of the lower extension plate 23, and two sliders 313 are fixedly provided on both sides of the lower end of the movable frame plate 31 corresponding to the two sliding grooves 231. The two sliders 313 are movably embedded in the two sliding grooves 231 respectively. The embedded movable structure of the sliding grooves 231 and the sliders 313 can prevent the movable grille 3 from positional deviation during movement. In addition, a groove 213 is formed on the side of the fixed frame plate 21 facing the movable frame plate 31 above the rectangular opening 211, and a protrusion (not shown in the figure) is protruded from the movable frame plate 31 corresponding to the groove 213. When the movable frame plate 31 moves toward the fixed frame plate 21 to fit together, the protrusion is aligned and embedded in the groove 213, thereby improving the stability of the movable frame plate 31 and the fixed frame plate 21 after fitting together, so as to facilitate the operation of inserting the grille main body (that is, the combination of the fixed grille and the movable grille) into the space set in the U-shaped frame 1.

[0026] In this embodiment, in order to enhance the horizontal stability of the grid body and the U-shaped frame 1, the grid body is connected to the U-shaped frame 1. Figure 2 As shown, two embedded plates 214 can be vertically fixedly combined on both sides of the fixed frame plate 21, and two embedded grooves 121 are respectively opened on the opposite sides of the two side plates 12 corresponding to the two embedded plates 214. The two embedded plates 214 can be movably slid into the two embedded grooves 121 so that the fixed frame plate 21 can be fixed between the two side plates 12 in a removable manner.

[0027] In this embodiment, in order to enhance the vertical stability of the grille body and the U-shaped frame 1 after being combined, the grille body is combined with the U-shaped frame 1. Figure 1 As shown, the sewage intercepting grille may also include two penetration blocks 122, two second screws 123 and two connecting blocks 215, wherein the two penetration blocks 122 are respectively fixedly connected to the upper end portions of the two side panels 12, and the two penetration blocks 122 are respectively provided with through second screw holes (not shown in the figure) facing each other, and the second screw holes have internal threads, and the two second screws 123 are respectively screwed into the two second screw holes, and the two connecting blocks 215 are fixedly connected to both sides of the upper end portion of the fixed frame plate 21 corresponding to the two penetration blocks 122, and the two connecting blocks 215 are respectively provided with insertion holes (not shown in the figure) corresponding to the two second screw holes, and the fixed frame plate 21 is fixed.

[0028] Combine Figure 4FIG. 1 shows another embodiment of the present invention. The structure of this embodiment is substantially the same as that of the previous embodiment, except that the intercepting grate is further equipped with a grate cleaning mechanism 4. Specifically, the grate cleaning mechanism 4 is primarily composed of a V-shaped plate 41, a cleaning brush 42, two fixed plates 43, and a reciprocating screw 44. Vertical guide slots 124 are defined on the sides of the two side plates 12 facing the movable grate 3 away from the fixed frame plate 21. The V-shaped plate 41 primarily comprises a vertically disposed mounting plate 411 and two guide plates 412. One end of each guide plate 412 is fixedly coupled to the other end of the mounting plate 411, forming a mounting space within the V-shaped plate 41. The cleaning brush 42 is mounted on the side of the mounting plate 411 within the mounting space. The other ends of each guide plate 412 are slidably inserted into the two guide slots 124. The two fixed plates 43 are fixedly coupled to the outer sides of the upper and lower ends of one of the guide slots 124, respectively. The reciprocating screw 44 is rotatably fixed to the two fixed plates 43 via bearings (not shown). The mounting plate 411 is threadedly engaged with the reciprocating screw 44 via a ball nut pair (not shown). By rotating the reciprocating screw 44, the U-shaped plate 41 and the cleaning brush body 42 are driven up and down to clean the movable grille 3 and the fixed grille 2. This allows the impurities stuck on the movable grille 3 and the fixed grille 2 to be brushed away, thereby extending the operating time of the sewage interception grille. It should be noted that since the movable grille 3 is movable, that is, the distance between the movable grille 3 and the cleaning brush body 42 is variable, the hardness of the bristles of the cleaning brush body 42 should not be too high, otherwise the structure of the bristles will be damaged when the movable grille 3 approaches the cleaning brush body 42. In addition, the grille cleaning mechanism 4 may also include two auxiliary fixing plates (not shown) and a sliding rod (not shown). The two auxiliary fixing plates are respectively fixedly coupled to the outer sides of the upper and lower ends of the other guide groove. The two ends of the sliding rod are fixed to the two auxiliary fixing plates. The mounting plate is provided with a sliding hole (not shown) at the position corresponding to the sliding rod. The sliding rod is slidably mounted through the sliding hole so that the V-shaped plate can be guided by the sliding rod to move, thereby improving the stability of the V-shaped plate during the up and down movement. In addition, the grille cleaning mechanism 4 may also include a drive motor 45. The drive motor 45 is mounted on the upper part of the fixed plate 43 located above. The upper end of the reciprocating screw rod 44 passes through the fixed plate 43 and is connected to the drive end of the drive motor 44, thereby improving the degree of automation of the sewage interception grille.

[0029] In summary, the utility model can be composed of a plurality of vertical bars in the rectangular opening of the fixed grille and a plurality of horizontal bars in the rectangular opening of the movable grille, which are stacked to form a grille for intercepting impurities in sewage. At the beginning of the use of the grille, the fixed grille and the movable grille can be fitted together by adjusting the horizontal moving mechanism to reduce the pores formed between the vertical bars and the horizontal bars, thereby improving the interception effect of impurities; and as the grille is used for a longer time, various fine impurities will gradually get stuck and clogged in the pores of the grille. At this time, by adjusting the horizontal moving mechanism to make the movable grille gradually move away from the fixed grille, the pores between the vertical bars and the horizontal bars are gradually increased, thereby gradually reducing the adverse effects of the stuck and clogged impurities on the grille to ensure that the grille has a continuously better impurity interception effect, thereby extending the sewage interception operation time of the grille by dynamically adjusting the size of the grille gap. When the sewage interception grille accumulates a large amount of impurities and needs to be thoroughly cleaned and maintained, it is only necessary to extract the fixed grille together with the movable grille from the setting space of the U-shaped frame to achieve cleaning and maintenance of the grille body. Thereafter, the cleaned grille body is reinstalled into the setting space to put the grille back into operation. The above-mentioned convenient loading and unloading operations of the grille body can greatly shorten its shutdown and maintenance time, thereby improving the overall operating efficiency of the sewage interception system.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Other equivalent changes made using the patent concept of the present invention should fall within the patent protection scope of the present invention.
