A fixed block is fixedly connected to the bottom of the discharge pipe, and the fixed block is fixedly connected to the top of the water inlet pipe.

[0018] The present invention provides a wastewater treatment device with an anti-blocking function. It has the following beneficial effects:

[0019] 1. When the filter barrel of the wastewater treatment device with an anti-blocking function rotates, it will drive the two spiral plates inside to move together, and the wastewater inside the filter barrel will be driven together. Thus, large-particle sand and gravel will be filtered inside the filter barrel, and the water will be thrown out of the filter barrel by centrifugal force, achieving a filtering effect. At the same time, when the spiral plates rotate, they will also press the wastewater inside the filter barrel downward, which can increase the pressure of the top water and accelerate the filtering efficiency.

[0020] 2. The wastewater treatment device with anti-blocking function. When the inclined plate rotates, it will push the wastewater that has been filtered once downward, increasing the top water pressure to enhance the filtration efficiency. The small granular sand and particulate suspensions accumulated on the top of the filter screen after filtration will be swept to the edge of the filter screen by the arc-shaped plate driven by the fixed rod, allowing them to fall into the mating gap between the mating pipe and the filter pipe, preventing accumulation near the filter screen, thereby increasing the filtration area and enhancing the filtration efficiency.

[0021] 3. The wastewater treatment device with anti-blocking function. Through the discharge mechanism, the sand and gravel that easily accumulate at the bottom of the filter barrel are rolled up and conveyed upward by the conveyor plate driven by the motor through the fixed rod, discharging the sand and gravel in the filter barrel. This can prevent the filter barrel from being blocked due to excessive accumulation of sand and gravel, thereby increasing the filtration efficiency.

[0022] 4. The wastewater treatment device with anti-blocking function. The filter barrel first filters the wastewater once, and the water filtered by the filter barrel will flow through the surface of the fixed rod, thereby cooling the motor inside the fixed rod, improving the discharge efficiency of the accumulated sand and gravel from the side, and enhancing the filtration efficiency from the side.

[0023] 5. The wastewater treatment device with anti-blocking function. When the second telescopic rod extends, the clamping block is inserted into the clamping ring, preventing the water flow from flowing out through the filter pipe. At this time, when the two second telescopic rods contract, the clamping ring will be pulled downward, allowing the water flow to flow out from the mating gap between the mating pipe and the filter pipe, flushing out the fine sand and gravel accumulated by the secondary filtration mechanism with water, and avoiding affecting the filtration efficiency due to accumulation.

[0024] 6. The wastewater treatment device with anti-blocking function. When the second telescopic rod extends upward and the clamping block is inserted into the clamping ring, at this time, cleaning water is continuously injected from the top of the baffle. The motor drives the connecting column to rotate, allowing the water flow to be discharged from the discharge cylinder, flushing the flow channel, and enabling rapid cleaning of the interior of the device, which is beneficial to improving the filtration efficiency.

The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] Embodiment 1

[0041] Spiral plate 63, the spiral plate 63 is fixedly connected inside the filter bucket 61.

[0042] There are two spiral plates 63. A discharge cylinder 64 is fixedly connected inside the blocking frame 62. The outer wall of the discharge cylinder 64 is provided with several drainage fine holes. A pulley 65 is fixedly connected outside the discharge cylinder 64.

A pulley motor 67 is fixedly connected to the outer wall of the water inlet pipe 1, and the pulley motor 67 is movably connected to the pulley 65 through the conveyor belt 66.

[0043] During use, the wastewater to be treated is discharged from the top of the blocking frame 62. At the same time, the pulley motor 67 drives the pulley 65 to rotate through the conveyor belt 66. The pulley 65 drives the discharge cylinder 64 to rotate.

[0045] Please refer to Figures 1-6 , on the basis of Embodiment 1, the present invention provides a technical solution:

[0046] The secondary filtering mechanism 7 includes a fixed rod 71.

Several inclined plates 72 are fixedly connected to the outer wall of the fixed rod 71, and all the inclined plates 72 are located inside the connecting pipe 2. Three arc plates 73 are fixedly connected to the outer wall of the fixed rod 71 at the bottom of the inclined plates 72.

[0047] A filter net 74 is fixedly connected to the top of the filter pipe 5. The filter net 74 is located at the bottom of the three arc plates 73. A snap ring 75 is fixedly connected to the inner wall of the filter pipe 5. A first telescopic rod 77 is fixedly connected to the bottom of the filter pipe 5 inside the snap ring 75. A snap block 76 is fixedly connected to the top of the first telescopic rod 77 at the bottom of the snap ring 75.

[0048] An opening ring 78 is provided at the bottom of the outer wall of the filter pipe 5 and is located at the bottom of the mating pipe 3. A receiving groove 710 is fixedly connected to the bottom of the outer wall of the filter pipe 5. Two second telescopic rods 79 are fixedly connected to the bottom of the opening ring 78, and the two second telescopic rods 79 are fixedly connected to the top of the receiving groove 710.

[0049] During use, the water filtered by the primary filtration mechanism 6 flows into the connecting pipe 2 through the inside of the water inlet pipe 1. The flowing water is filtered again by the filter net 74. When flowing through the connecting pipe 2, the filter barrel 61 drives the fixed rod 71 to rotate during rotation. The fixed rod 71 drives several inclined plates 72 on the outer wall to rotate. When the inclined plates 72 rotate, they will push down the wastewater that has been filtered once to increase the top water pressure and thus increase the filtration efficiency. The small granular sand and particulate suspensions accumulated on the top of the filter net 74 will be swept to the edge of the filter net 74 by the arc-shaped plate 73 driven by the fixed rod 71, allowing them to fall into the mating gap between the mating pipe 3 and the filter pipe 5, preventing accumulation near the filter net 74, thereby increasing the filtration area and enhancing the filtration efficiency.

[0050] Embodiment 3

[0051] Please refer to Figures 1-8 , based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution:

[0052] The discharge mechanism 8 includes a motor 81. The motor 81 is fixedly connected inside the fixed rod 71. A connecting column 82 is fixedly connected to the top of the motor 81, and the connecting column 82 is fixedly connected to the output shaft top of the motor 81. Drainage fine holes are provided on the outer wall of the discharge cylinder 64.

[0053] A conveying plate 83 is fixedly connected to the outer wall of the connecting column 82. The conveying plate 83 is provided with several drainage fine holes, and several outward plates 84 are fixedly connected to the outer wall of the connecting column 82.

A fixed block 86 is fixedly connected to the bottom of the discharge pipe 85, and the fixed block 86 is fixedly connected to the top of the water inlet pipe 1.

[0055] During use, the rotation of the filter barrel 61 filters out water and accumulates large - particle sand and gravel at the inner bottom. Since the bottom cross - section of the filter barrel 61 is trapezoidal, it is easy for sand and gravel to accumulate at the bottom. The sand and gravel are rolled up and transported upward by the conveyor plate 83 driven by the electric motor 81 through the fixed rod 71. During the transportation process, the sand and gravel near the connecting column 82 are driven to rotate by the outer plate 84, and the inner sand and gravel generate centrifugal force, which squeezes the outer sand and gravel. As a result, the water adhering to the surface of the outer sand and gravel is discharged into the filter barrel through the small holes on the discharge cylinder 64. At the same time, during the upward transportation of the sand and gravel, the water on the surface of the sand and gravel flows down along the small holes on the conveyor plate 83 and returns to the filter barrel 61. The transported sand and gravel are sent to the discharge pipe 85 for discharge, discharging the sand and gravel in the filter barrel 61, which can prevent the sand and gravel in the filter barrel 61 from being blocked due to excessive accumulation, thereby increasing the filtration efficiency. The water filtered by the filter barrel 61 flows through the surface of the fixed rod 71, which can cool the electric motor 81 inside the fixed rod 71, and can improve the discharge efficiency of the accumulated sand and gravel from the side, thus enhancing the filtration efficiency from the side.
