Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for environmental engineering. Background Technique

[0002] Environmental engineering refers to the application of scientific and engineering principles to improve the environment, including the quality of air, water and land resources, to protect human health and ecosystems. By comprehensively applying technologies, management and policy means, it aims to solve environmental problems, promote sustainable development, and ensure the balance of human health and ecosystems. Among them, in the field of water resource management, sewage treatment devices are needed to treat sewage.

[0003] Sewage treatment needs to be carried out step by step through sedimentation tanks, anoxic tanks, reaction tanks and disinfection tanks, etc. Generally, inclined tube sedimentation is used in sedimentation tanks. After sewage enters the sedimentation tank, it will float upward along the inclined tubes, while sludge will sink along the inner wall of the inclined tubes under the action of gravity, and the supernatant will be discharged from the top of the inclined tubes. However, in this process, sludge will gradually accumulate on the inner wall of the inclined tubes, resulting in poor subsequent sewage treatment effect. At present, the inclined tubes are all fixed in the sedimentation tank separately by bolts. If the inclined tubes need to be cleaned, the water in the sedimentation tank needs to be drained first and then disassembled for cleaning, resulting in troublesome installation, disassembly and cleaning of the inclined tubes. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a sewage treatment device for environmental engineering.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a sewage treatment device for environmental engineering, including a sedimentation tank, a water inlet pipe is fixed on one side of the top of the sedimentation tank, a water outlet pipe is fixed on the side wall of the sedimentation tank opposite to the water inlet pipe, a sludge tank is arranged at the bottom of the sedimentation tank, a sloping plate is fixed on the inner side of the sedimentation tank and close to the water inlet pipe, and a bottom grid plate is fixed at the bottom of the sloping plate. A plurality of inclined tubes are arranged on the upper surface of the bottom grid plate. A support assembly for supporting the inclined tubes is fixed between the sloping plate and the inner wall of the sedimentation tank. A top grid plate is arranged above the tops of the plurality of inclined tubes. An extrusion assembly for extruding the top grid plate is arranged on the top of the sedimentation tank. A sludge pump is fixed on the outer side wall of the sedimentation tank.

[0006] Further, the support assembly includes a cross plate, and the cross plate is located above the bottom grid plate. A plurality of inclined holes for passing through the inclined tubes are opened on the cross plate.

[0008] Further, a backing plate is fixed on the inner side wall of the sedimentation tank and below the water outlet pipe. The lower surface of the top grid plate is attached to the backing plate and the tops of the plurality of inclined tubes.

[0009] Furthermore, the water outlet pipe is located above a plurality of inclined pipes.

[0010] Furthermore, the extrusion assembly includes a U-shaped plate clamped to the top of the side wall of the sedimentation tank, a side plate is fixed to the bottom end of the U-shaped plate, and a round tube is fixed to the lower surface of the side plate, a movable rod is slidably connected inside the round tube, and a pressure plate is fixed to the bottom end of the movable rod, and the pressure plate is located on the upper surface of the top grid plate, the top of the movable rod and the top wall of the round tube are fixedly connected with a spring, and a locking bolt is passed through and threadedly connected to the side wall of the U-shaped plate.

A support assembly 8 for supporting the inclined tubes 7 is fixed between the inclined plate 5 and the inner wall of the sedimentation tank 1. A top grille plate 9 is arranged above the plurality of inclined tubes 7. An extrusion assembly 11 for extruding the top grille plate 9 is arranged on the top of the sedimentation tank 1. A sludge pump 12 is fixed on the outer side wall of the sedimentation tank 1.

[0023] The support assembly 8 includes a horizontal plate 81, and the horizontal plate 81 is located above the bottom grille plate 6. A plurality of inclined holes 82 for passing through the inclined tubes 7 are formed in the horizontal plate 81.

[0024] When installing the inclined tubes 7, the inclined tubes 7 can be directly inserted into the inclined holes 82, and the inclined tubes 7 are supported and limited by the inclined holes 82 on the horizontal plate 81.

[0025] A sealing ring is arranged on the inner side wall of the inclined hole 82, and the sealing ring is attached to the outer wall of the inclined tube 7.

[0026] The sealing ring can increase the sealing performance between the inclined tube 7 and the inclined hole 82, so that the sewage can only flow along the inside of the inclined tube 7.

[0027] A padding plate 10 is fixed on the inner side wall of the sedimentation tank 1 and below the outlet pipe 3. The lower surface of the top grille plate 9 is attached to the padding plate 10 and the top ends of the plurality of inclined tubes 7.

[0028] The upper and lower positions of a number of inclined tubes 7 can be limited and fixed by the top grid plate 9 and the bottom grid plate 6, and the installation and fixation of the inclined tubes 7 are realized in cooperation with the support assembly 8.

[0029] The water outlet pipe 3 is located above a number of inclined tubes 7. After the clear water is discharged from the top of the inclined tubes 7, it is then discharged from the water outlet pipe 3.

[0030] The extrusion assembly 11 includes a U-shaped plate 111 clamped to the top end of the side wall of the sedimentation tank 1. A side plate 112 is fixed to the bottom end of the U-shaped plate 111, and a round tube 113 is fixed to the lower surface of the side plate 112. A movable rod 114 is slidably connected inside the round tube 113, and a pressing plate 116 is fixed to the bottom end of the movable rod 114.

After all the inclined tubes 7 are inserted, place the top grid plate 9 on the top of a number of inclined tubes 7, then clamp the U-shaped plate 111 to the top end of the side wall of the sedimentation tank 1, and tighten the locking bolt 117 to fix the U-shaped plate 111. At this time, the bottom of the U-shaped plate 111 squeezes the movable rod 114 and the pressing plate 116 through the spring 115, and the pressing plate 116 is used to tightly fix the top grid plate 9. When disassembling, first loosen the locking bolt 117 to disassemble the U-shaped plate 111, then remove the top grid plate 9, and then pull out the inclined tubes 7 upward, which is convenient for replacing or cleaning the inclined tubes 7.

[0033] Working principle: Sewage is added to the sedimentation tank 1 through the water inlet pipe 2. After the sewage enters the sedimentation tank 1, the sludge in the sewage first passes through the bottom grid plate 6 and enters the inclined tubes 7. The sludge slides down along the inner wall of the inclined tubes 7 under the action of gravity and finally falls into the sludge tank 4, while the clear water passes through the top grid plate 9 and is discharged along the water outlet pipe 3. When there is more sludge in the sludge tank 4, the sludge can be pumped out through the sludge pump 12.
