[0012] The present invention provides a sewage treatment device for tunnel bottom karst cave construction. It has the following beneficial effects: 1. The sewage treatment equipment constructed in the tunnel bottom cave will push the sediment out of the sediment discharge pipe through the barrier plate, and then let the sediment fall into the top of the enrichment filter inside the enrichment box. The water mixed with the sediment will gradually seep downwards, pass through the enrichment filter and fall into the bottom of the enrichment box, and then flow back to the inside of the filter tube through the return pipe, and be discharged from the bottom of the filter tube together with the filtered water, so as to more fully treat the sewage.

[0013] 2. The sewage treatment equipment constructed in the karst cave at the bottom of the tunnel rotates the fan blades on the outer wall through the first connecting rod. The rotation of the fan blades will continuously push the external gas into the inside of the filter tube, increasing the air pressure on the top of the filter plate, thereby allowing the air pressure to push the sewage through the top of the filter plate for filtration, which can make the sewage more fully filtered and reduce the water mixed in the sediment.

[0014] 3. The sewage treatment equipment constructed in the karst cave at the bottom of the tunnel pushes the air through the filter plate through the fan blades, generating a flowing airflow inside the filter tube. According to the Bernoulli principle, the return pipe will generate an inhaled airflow, which will act on the sediment on the top of the enrichment filter. The inhaled airflow generated by the return pipe will accelerate the water on the sediment on the top of the enrichment filter to fall into the enrichment box, and then return to the filter tube through the return pipe, which can promote the recovery of water in the sediment.

[0015] 4. The sewage treatment equipment constructed in the karst cave at the bottom of the tunnel is continuously extended and retracted by the telescopic rod, so that the filter plate vibrates up and down. The vibration can destroy the initial accumulation structure of sediment formed on the filter screen. At the same time, it helps to shake off the sediment in the pores inside the filter plate, which can promote the filtration of sediment. At the same time, the lifting rod will vibrate up and down with the enrichment box, so that the sediment on the top of the enrichment filter screen vibrates up and down together, which promotes the water on the sediment on the top of the enrichment filter screen to pass through the enrichment filter screen and return to the inside of the filter tube through the return pipe at the bottom of the enrichment box, which can further filter out the water mixed in the sediment and can more fully treat the sewage.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0020] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: a sewage treatment equipment for tunnel bottom cave construction, comprising a filter tube 1, a water suction pipe 2 is fixedly connected to the outer wall of the filter tube 1, a water suction head 3 is fixedly connected to the end of the water suction pipe 2 away from the filter tube 1, a water suction motor 4 is fixedly connected to the water suction head 3, a water wringing screw 5 is provided inside the water suction head 3, and the water wringing screw 5 is fixedly connected to the output shaft of the water suction motor 4, a filter plate 6 is provided inside the filter tube 1, a filter fixing frame 9 is fixedly connected to the outer wall of the filter tube 1, a filter pressing mechanism 7 is fixedly connected to the outer wall of the water suction head 3, and an enrichment mechanism 8 is fixedly connected to the outer wall of the filter tube 1; The filter press mechanism 7 comprises: The barrier net 701 is fixedly connected to the outer wall of the water suction head 3; A sweeping rod 702, which is movably connected to the outside of the barrier net 701 and fixedly connected to the water-tightening screw rod 5; The fan blade 707 is arranged inside the filter tube 1 and located on the top of the filter plate 6.

[0021] Fix the equipment through the filter fixing frame 9, start the water suction motor 4, and let the water suction motor 4 drive the water screw 5 to rotate. The rotation of the water screw 5 will send the sewage into the inside of the filter tube 1 through the suction pipe 2. At the same time, the barrier net 701 will prevent large pieces of gravel from entering the inside of the filter tube 1 through the suction pipe 2 along with the sewage. When the water screw 5 is driven to rotate, the sweeping rod 702 will be rotated, thereby preventing the debris from accumulating on the barrier net 701 and affecting the smooth flow of water. The sewage is filtered through the filter plate 6 inside the filter tube 1, and the filtered water will be discharged from the bottom of the filter tube 1.

[0022] A motor fixing bracket 703 is fixedly connected to the top of the filter tube 1, a rotating motor 704 is fixedly connected inside the motor fixing bracket 703, a first connecting rod 705 is fixedly connected to the bottom of the rotating motor 704, and the first connecting rod 705 is fixedly connected to the output shaft of the rotating motor 704, and the fan blade 707 is fixedly connected to the outer wall of the first connecting rod 705.

[0023] When sewage treatment is carried out, the rotating motor 704 is started at the same time, and the rotating motor 704 drives the first connecting rod 705 to rotate. When the first connecting rod 705 rotates, the fan blades 707 on the outer wall will rotate. The rotation of the fan blades 707 will continuously push the external gas into the inside of the filter tube 1, so that the air pressure on the top of the filter plate 6 increases, thereby allowing the air pressure to push the sewage through the top of the filter plate 6 for filtration.

[0024] The bottom of the first connecting rod 705 is movably connected to the second connecting rod 706, and the first connecting rod 705 can rotate with the second connecting rod 706. The outer wall of the second connecting rod 706 is located at the top of the second connecting rod 706 and is fixedly connected to a sweeping plate 708. The top of the second connecting rod 706 is located inside the first connecting rod 705 and is fixedly connected to a spring 709. The spring 709 will push the second connecting rod 706 downward so that the bottom of the sweeping plate 708 is always in contact with the filter plate 6.

[0025] When the first connecting rod 705 is rotated by the rotating motor 704, the second connecting rod 706 will be rotated together, and the second connecting rod 706 will rotate together with the sweeping plate 708 on the outer wall. The sweeping plate 708 will continuously sweep the mud and sand filtered from the top of the filter plate 6, and sweep the mud and sand on the top of the filter plate 6 to the edge through the action of centrifugal force, so as to avoid mud and sand clogging inside the filter plate 6.

[0026] Example 2: Please refer to Figure 1-9Based on the first embodiment, the present invention provides a technical solution: The enrichment mechanism 8 includes a sand discharge pipe 801, which is fixedly connected to the outer wall of the filter tube 1. Two rollers 802 are movably connected inside the sand discharge pipe 801. A conveyor belt 804 is provided inside the sand discharge pipe 801, and the conveyor belt 804 is movably connected to the outer walls of the two rollers 802. A sand discharge motor 803 is fixedly connected to the outer wall of the sand discharge pipe 801, and the output shaft of the sand discharge motor 803 is fixedly connected to one of the rollers 802. Several blocking plates 805 are fixedly connected to the outer wall of the conveyor belt 804, and the blocking plates 805 and the conveyor belt 804 will serve to close the internal cross-section of the sand discharge pipe 801.

[0027] When sewage treatment is being carried out, the sand discharge motor 803 is started at the same time. The sand discharge motor 803 will drive the corresponding roller 802 to rotate, and through cooperation with another roller 802, it will drive the conveyor belt 804 to move. The rotating sweeping of the sweeping plate 708 will allow the sediment to enter the sand discharge pipe 801. The movement of the conveyor belt 804 will allow the barrier plate 805 to continuously push the sediment to the outside, so that the sediment can be discharged from the inside of the filter tube 1.

[0028] The outer wall of the filter tube 1 is movably connected to an enrichment box 806 at the bottom of the sand discharge pipe 801, and an enrichment filter 807 is fixedly connected inside the enrichment box 806. The bottom of the enrichment box 806 is fixedly connected to a return pipe 808, and the bottom of the return pipe 808 is fixedly connected to the filter tube 1.

[0029] The sediment will be pushed out of the sediment discharge pipe 801 by the blocking plate 805, and then fall into the inside of the enrichment box 806. The discharged sediment will be on the top of the enrichment filter 807 on the top of the enrichment box 806. At this time, the water mixed in the sediment will gradually seep downward, pass through the enrichment filter 807 and fall into the bottom of the enrichment box 806, and then flow back to the inside of the filter tube 1 through the return pipe 808, and be discharged from the bottom of the filter tube 1 together with the filtered water.

[0030] The rotating motor 704 rotates with the fan blades 707 through the first connecting rod 705, pushing the air through the filter plate 6, and also generating a flowing airflow inside the filter tube 1. According to the Bernoulli principle, the flowing airflow has a relatively low pressure, which will cause the return pipe 808 to generate an inhaled airflow. This airflow will act on the sediment on the top of the enrichment filter 807. The inhaled airflow generated by the return pipe 808 will accelerate the water on the sediment on the top of the enrichment filter 807 to fall into the enrichment box 806, and then flow back to the inside of the filter tube 1 through the return pipe 808.

[0031] Inside the filter tube 1 , a fixing rod 812 is fixedly connected to the bottom of the filter plate 6 , a telescopic rod 811 is fixedly connected to the top of the fixing rod 812 , and the top of the telescopic rod 811 is fixedly connected to the bottom of the filter plate 6 .

[0032] When sewage treatment is being carried out, the telescopic rod 811 is started synchronously, and the telescopic rod 811 is continuously extended and retracted, thereby causing the filter plate 6 to vibrate up and down inside the filter tube 1. The vibration can destroy the initial accumulation structure of the sediment formed on the filter screen. At the same time, the up and down vibration also helps to shake off the sediment in the pores inside the filter plate 6.

[0033] The outer wall of the telescopic rod 811 is fixedly connected to a lifting rod 809 , and the lifting rod 809 is fixedly connected to the bottom of the enrichment box 806 .

[0034] A groove for the lifting rod 809 to move up and down is provided on the outer wall of the filter tube 1. A sealing plate 810 is fixedly connected to the outer wall of the lifting rod 809. The sealing plate 810 can seal the corresponding groove on the filter tube 1 to prevent the lifting rod 809 from moving up and down and allowing the water inside the filter tube 1 to leak out of the outer wall of the filter tube 1 through the corresponding groove.

[0035] The telescopic rod 811 continuously extends and retracts, and at the same time, it will cause the lifting rod 809 to vibrate up and down. The lifting rod 809 will cause the enrichment box 806 to vibrate up and down synchronously. The enrichment box 806 will cause the enrichment filter 807 and the sediment on the top of the enrichment filter 807 to vibrate up and down together. This will promote the water on the sediment on the top of the enrichment filter 807 to pass through the enrichment filter 807 and flow back to the inside of the filter tube 1 through the return pipe 808 at the bottom of the enrichment box 806.

[0036] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
