Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge interception device. Background Technology

[0002] During the wastewater collection process, wastewater needs to undergo sludge removal treatment. This sludge removal operation is to remove large particles, suspended solids, and some solid waste from the water. This prevents these substances from clogging or damaging subsequent treatment facilities such as pumping stations, pipelines, and sedimentation tanks. Existing sludge removal methods mostly involve setting up screens or grates to intercept solid particles and debris larger than a certain size. While screens can effectively prevent larger particles from entering the downstream treatment system, they require regular manual cleaning, which increases labor costs and maintenance difficulty. Furthermore, the debris in wastewater often has a foul odor and may contain pathogens, so manually cleaning screens may pose certain risks to the health and safety of workers. Utility Model Content

A filter hole for filtering impurities is opened on one side of the filter pipe. A spiral conveyor rod is rotatably placed inside the conveying pipe, and the interiors of the filter pipe and the squeezing pipe are slidably connected to the spiral conveyor rod. One end of the spiral conveyor rod is provided with a squeezing part, which includes a squeezing plate slidably installed at the end of the spiral conveyor rod for squeezing out impurities and moisture. A spring is fixedly connected to the outside of the spiral conveyor rod to drive the squeezing plate to fit against the end of the squeezing pipe.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a slag-blocking device, comprising: a conveying pipe, the conveying pipe including a filter pipe 1 and a squeezing pipe 2 fixedly connected to its ends, the squeezing pipe 2 having a funnel-shaped structure, the larger diameter end of the squeezing pipe 2 being fixedly connected to the filter pipe 1, and a filter hole 4 for filtering impurities being opened on one side of the filter pipe; a spiral conveying rod 3 rotatably placed inside the conveying pipe, and the interiors of the filter pipe 1 and the squeezing pipe 2 being slidably connected to the spiral conveying rod 3, one end of the spiral conveying rod 3 being provided with a squeezing part, the squeezing part including a squeezing plate 7 slidably installed at the end of the spiral conveying rod 3 for squeezing impurities and moisture, a spring 8 fixedly connected to the outside of the spiral conveying rod 3 to drive the squeezing plate 7 to fit against the end of the squeezing pipe 2, a limiting block fixedly connected to one end of the spiral conveying rod 3, and one end of the limiting block being fixedly connected to the spring 8, one end of the spring 8 contacting the squeezing plate 7 and applying a certain thrust to the squeezing plate 7.

[0016] It should be noted that a control switch is provided in this embodiment. The control switch controls the drive motor 6 to be energized, and the drive motor 6 drives the spiral conveyor rod 3 to rotate. This spiral conveyor rod 3 transports impurities inside the filter holes 4 towards the squeezing pipe 2. After water enters the filter pipe 1, it flows out through the filter holes 4, while the impurities are filtered inside the filter pipe 1. The spiral conveyor rod 3 then transports these impurities along the filter pipe 1 and the squeezing pipe 2 towards the end of the squeezing pipe 2. When the impurities reach the end of the squeezing pipe 2, the squeezing plate 7, under the action of the spring 8, seals the end of the squeezing pipe 2, causing more and more impurities to accumulate at the end. Under the pushing action of the spiral conveyor rod 3, the water in the impurities is squeezed out. When the squeezing force exceeds the elastic force of the spring 8, the squeezing plate 7 compresses the spring 8 to one side, causing the squeezing plate 7 to separate from the end of the squeezing pipe 2. The squeezed impurities are discharged through the gap between the squeezing pipe 2 and the squeezing plate 7, thus achieving the collection of impurities after wastewater filtration and the squeezing treatment of impurities in the incoming water.

[0017] In one embodiment, the filter tube 1 has a water inlet at the top, and a water receiving funnel 16 is fixedly installed at the top of the water inlet.

[0018] It should be noted that in this embodiment, the sewage is introduced into the inlet through the water receiving funnel 16, and then enters the filter pipe 1 through the inlet. The water is filtered through the filter holes 4 on the side and end of the filter pipe 1.

[0019] In one embodiment, a connecting frame 5 is fixedly connected to the outside of the squeezing pipe 2, a drive motor 6 is fixedly connected to one end of the connecting frame 5, the output end of the drive motor 6 is fixedly connected to the screw conveyor 3, and a receiving trough 9 is fixedly connected to one end of the squeezing pipe 2.

[0020] It should be noted that in this embodiment, the drive motor 6 is connected to the squeezing pipe 2 via the connecting frame 5, which has a "U"-shaped structure. One end of the screw conveyor 3 rotates with the connecting frame 5, and the connecting frame 5 drives the screw conveyor 3 to rotate via a coupling, thereby conveying the debris to the end of the squeezing pipe 2. When the debris is squeezed and pushed open by the squeezing plate 7, the debris flows downward along the receiving trough 9, thereby collecting the debris.

[0021] In one embodiment, a second filter hole 11 is provided on the outer side of one end of the squeezing pipe 2 for discharging the squeezed water, and a water receiving groove 10 is fixedly connected to the outer side of the squeezing pipe 2 at the position corresponding to the second filter hole 11.

[0022] It should be noted that, in this embodiment, under the obstruction of the squeezing plate 7 and the spring 8, the debris is squeezed by the spiral conveying rod 3 towards one end of the squeezing pipe 2, and it accumulates at the end of the squeezing pipe 2 and at the position corresponding to the second filter hole 11. Under the squeezing force, the water of the impurities flows downward into the water receiving tank 10 through the second filter hole 11, and flows to the water pool through one end of the water receiving tank 10.

[0023] In one embodiment, two fixed plates 13 are symmetrically fixed to the outer side of the filter tube 1. A support frame 12 is rotatably connected to the outer side of the two fixed plates 13. A limiting part is provided on the outer side of the fixed plate 13 to limit the included angle between the support frame 12 and the filter tube 1. The limiting part includes a positioning pin 14 inserted into one side of the support frame 12. The fixed plate 13 has a positioning hole 15 that cooperates with the positioning pin 14.

[0024] It should be noted that, in this embodiment, when installing the filter pipe 1, the outlet of the squeezing pipe 2 is tilted upwards. The support frame 12 is rotated outside the fixed plate 13. When it is rotated to a suitable position, the positioning pin 14 is inserted through the support frame 12 into the positioning hole 15. Angle irons are fixed to both sides of the filter pipe 1. The angle irons are installed and connected to the sewage collection tank, so that the filter hole 4 is located above the inside of the sewage collection tank.
