DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 3 In an embodiment of the utility model, an interception device for a sewage treatment pool includes an interception box 1, the interior of the interception box 1 is divided into an interception area 2 and a filtration area 3, and the interception area 2 is located above one side of the filtration area 3, and the interior of the interception area 2 is provided with an interception mechanism for intercepting and treating bag-shaped floating objects in sewage, the interception mechanism includes a sealing cylinder 41, an interception rod 42, a cleaning plate 43 and a connecting rod 44, one side of the interception box 1 is slidably connected with a sealing cylinder 41 extending to the interception area 2, one side of the inner wall of the interception area 2 is welded with a plurality of interception rods 42 in parallel, the other ends of the interception rods 42 are slidably inserted into one side of the sealing cylinder 41, the surface of the interception rod 42 is penetrated by a cleaning plate 43 that is slidably connected, and both ends of the cleaning plate 43 close to the sealing cylinder 41 are welded with connecting rods 44, and the other ends of the connecting rods 44 are welded to the side of the sealing cylinder 41.

[0022] When in use, the sewage is transported into the interception area 2 from the water inlet at the top of the interception box 1. At this time, the interception rod 42 can intercept bag-shaped, long strip-shaped and other floating objects in the sewage, and the intercepted garbage is hung on the interception rod 42. When all the sewage passes through the interception area 2 and is discharged into the interception box 1, when it is necessary to clean the garbage on the surface of the interception rod 42, the operator pulls the handle on one side of the sealing cylinder 41 to make the sealing cylinder 41 separate from the interception box 1. When the sealing cylinder 41 separates from the interception box 1, it is also separated from one end of the interception rod 42. When the sealing cylinder 41 is pulled and moved, the cleaning plate 43 is driven by the connecting rod 44 to slide along the surface of the interception rod 42. When the cleaning plate 43 moves, the garbage hanging on the surface of the interception rod 42 can be pulled together, so that the garbage is moved to the outside of the interception box 1 along with the cleaning plate 43 by continuously pulling the sealing cylinder 41. At this time, a trash can can be placed on one side of the interception box 1 to facilitate the collection of garbage.

[0023] The bottom of the filter area 3 is welded with a first slope 9 and a second slope 10 in sequence, and the bottom ends of the inclined surfaces of the first slope 9 and the second slope 10 are provided with a storage mechanism for storing garbage in sewage, and the storage mechanism includes a storage frame 51 and a limiting rod 52. The bottom ends of the inclined surfaces of the first slope 9 and the second slope 10 are slidably connected with the storage frame 51 located at the bottom of the filter area 3, and a limiting groove 11 is provided on one side of the inner wall of the interception box 1 close to the storage frame 51, and the inside of the limiting groove 11 is slidably connected to the limiting rod 52, and the other end of the limiting rod 52 is welded to one side of the storage frame 51. The storage frame 51 is similar to a shovel shape and has through holes 53 on all sides. The through holes 53 are provided for sewage to flow out of the storage frame 51.

[0024] The top of the storage frame 51 is connected to a lifting mechanism located at the top of the interception box 1 for lifting it and discharging sewage. The lifting mechanism includes a fixed plate 61, a first motor 62, a round rod 63, a winding drum 64 and a pulling rope 65. A through slot 12 connected to the filtration area 3 and located above the storage frame 51 is opened on the top of the interception box 1. Fixed plates 61 located at the top of the interception box 1 are welded on both sides of the through slot 12. One side of one group of fixed plates 61 is bolted side by side with the first motor 62. The output end of the first motor 62 is fixedly connected to the round rod 63 through a rotating shaft. The other end of the round rod 63 passes through the fixed plate 61 and is rotatably connected to the inside of another fixed plate 61. The surface of the round rod 63 is symmetrically welded with a winding drum 64, and the surface of the winding drum 64 is wrapped with a pulling rope 65. Fixed hooks 66 distributed in a rectangular shape are welded to the top of the storage frame 51, and the end of the pulling rope 65 away from the winding drum 64 is hung on the fixed hook 66.

[0025] A filtering mechanism for filtering block garbage in sewage is provided on one side of the storage frame 51 away from the bottom ends of the inclined surfaces of the first slope 9 and the second slope 10, and is located in the filtering area 3. The filtering mechanism includes a first filter plate 71 and a second filter plate 72. A mounting plate 13 located in the filtering area 3 is welded to one side of the storage frame 51 away from the bottom ends of the inclined surfaces of the first slope 9 and the second slope 10. The tops of the mounting plates 13 are respectively and sequentially fixedly connected with the first filter plates 71 and the second filter plates 72. The top ends of the first filter plates 71 and the second filter plates 72 are fixedly installed on the inner wall of the interception box 1, and the filtering holes of the first filter plates 71 are larger than the filtering holes of the second filter plates 72, so as to filter and block block garbage of different sizes in turn.

[0026] When in use, when sewage enters the filtering area 3 after preliminary treatment by the interception mechanism, the block garbage is filtered and blocked by the first filter plate 71 and the second filter plate 72 in sequence and falls into the storage frame 51 respectively. When the garbage in the storage frame 51 needs to be cleaned and poured out, the operator simultaneously starts the first motor 62 on one side of one of the fixed plates 61. When the output end of the first motor 62 rotates, the round rod 63 connected to it is driven to rotate accordingly, so that the winding drum 64 rotates and reels the pulling rope 65. When the pulling rope 65 is rotated and reeled, the storage frame 51 is moved upward through the fixed hook 66. Movement, when the storage frame 51 moves, the limit rod 52 slides and moves in the limit groove 11, and the limit rod 52 is used to limit the upward or downward position of the storage frame 51. When the storage frame 51 moves up to the top of the interception box 1 through the through groove 12, the external trash can is placed on the top of the interception box 1, and then the operator controls the first motor 62 close to the side of the trash can to stop running. At this time, the other first motor 62 is still running, so that the storage frame 51 tilts toward one side of the trash can, and then the garbage in the storage frame 51 is dumped out. The operation is simple and there is no need to manually clean the garbage in the storage frame 51, which saves trouble and effort.

[0027] The first filter plate 71 and the second filter plate 72 are each provided with a cleaning mechanism for cleaning the surface thereof on one side close to the storage frame 51, and the cleaning mechanism includes a cleaning brush 81, a support rod 82, a threaded rod 83 and a second motor 84. A cleaning brush 81 is each provided on one side of the first filter plate 71 and the second filter plate 72 close to the storage frame 51, and the brush ends of the cleaning brush 81 are in contact with the surfaces of the first filter plate 71 and the second filter plate 72, and a support rod 82 and a threaded rod 83 are respectively provided at the bottom and top ends of one side of the cleaning brush 81, and both ends of the support rod 82 pass through the cleaning brush 81 and are welded to the inner wall of the interception box 1, one end of the threaded rod 83 passes through the cleaning brush 81 and is rotatably connected to the inner wall of the interception box 1 through a bearing seat, a second motor 84 is symmetrically installed on one side of the interception box 1 through bolts, and the other end of the threaded rod 83 passes through the interception box 1 and is fixedly connected to the output end of the second motor 84 through a rotating shaft, the cleaning brush 81 is rotatably connected to the threaded rod 83 through a thread and is slidably connected to the support rod 82.

[0028] During use, when it is necessary to clean the surface of the first filter plate 71 and the second filter plate 72, the second motor 84 is started. When the output end of the second motor 84 rotates, the threaded rod 83 is driven to rotate accordingly, so that the cleaning brush 81 moves in a translational motion to clean the impurities and garbage on the surface of the first filter plate 71 and the second filter plate 72, thereby avoiding blockage caused by excessive impurities and garbage on the surface of the first filter plate 71 and the second filter plate 72, which affects the efficiency of filtering and draining. When the cleaning brush 81 moves in a translational motion, the bottom end of one side thereof slides on the surface of the support rod 82 at the same time. The support rod 82 is used to provide stable support for the cleaning brush 81 during the cleaning operation.

[0029] Working principle: When the interception device for the sewage treatment pool is to be used, the sewage is first transported from the water inlet into the interception box 1. When the sewage flows through the interception area 2, the bag-shaped floating objects mixed in the sewage are intercepted by the interception mechanism, and then the preliminarily treated sewage flows into the filtration area 3. At this time, the first filter plate 71 and the second filter plate 72 intercept and block the block garbage in the sewage in turn, and the blocked block garbage falls into the storage frame 51 in turn. Then the intercepted sewage is discharged through the sewage outlet at the bottom end of the side of the interception box 1. When the sewage interception treatment is completed and the intercepted garbage needs to be cleaned, at this time, by pulling the handle on one side of the sealing cylinder 41, the sealing cylinder 41 drives the cleaning plate 43 to the interception rod 4 through the connecting rod 44. 2 is pulled out of the interception box 1, and then the second motor 84 is started to control the cleaning mechanism to operate the garbage retained on the surfaces of the first filter plate 71 and the second filter plate 72 to clean the garbage into the storage frame 51, and then the first motor 62 is started to operate the lifting mechanism, and the pulling rope 65 is continuously wound by the winding drum 64, so that the storage frame 51 is moved up to the top of the interception box 1 through the through slot 12, and then the external trash can is placed on the top of the interception box 1, and the first motor 62 near the trash can is controlled to stop running. At this time, the other first motor 62 continues to run to tilt the storage frame 51, so that the garbage inside it is poured into the external trash can. The operation is simple, labor-saving and easy, and work efficiency is improved.
