Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a treatment device for high-concentration difficult-to-degrade organic wastewater. Background Art

[0002] UASB is generally used to treat high-concentration organic wastewater. The sewage containing a large amount of sludge (mud content 3000 mg / L) in the UASB outlet pipe is first mixed with the PAM added to the pipe in the pipe mixer. After the sludge and PAM are mixed, a large number of easily settleable flocs are formed. Then, the sludge and water are separated by entering the inclined tube sedimentation integrated device. The sludge is collected and concentrated at the bottom of the sedimentation tank, and the sewage flows out from the upper part of the sedimentation tank. The concentrated sludge is pumped back into the reactor through the sludge pump.

[0003] The existing related technologies often have the following defects: when discharging the sludge from the sludge discharge pipe, the connecting pipe on the sludge pump needs to be connected to the sludge discharge pipe. Because the existing connection method is to use a flange to connect the connecting pipe to the sludge discharge pipe, and the flange connection requires precise installation and adjustment, if it is not installed properly, it is easy to cause the connection to loosen or deviate, thereby affecting the tightness of the connection and may cause the risk of pipeline leakage.

[0016] Preferably, a plurality of protrusions are fixedly connected to the surface of the arc-shaped plate, and the protrusions are arc-shaped blocks.

[0017] The effect achieved by the above components is that the connecting pipe slides along the surface of the protrusion, and the protrusion reduces the friction between the arc plate and the connecting pipe, thereby facilitating the movement of the connecting pipe.

Two limiting rods 705 are fixedly connected to the surface of the clamping block 703, and the two limiting rods 705 both slide through the mud discharge pipe 5. When the limiting rod 705 moves, it will slide in the mud discharge pipe 5, and the limiting rod 705 reaches the effect of limiting the moving path of the clamping block 703, thereby preventing the clamping block 703 from rotating during movement. The arc surface of the mud discharge pipe 5 is provided with a plurality of limiting grooves 706, and the surface of the connecting pipe 6 is fixedly connected with a plurality of L-shaped plates 707, the size of the L-shaped plates 707 and the limiting grooves 706 are adapted, and the L-shaped plates 707 will slide with the inner wall of the limiting grooves 706, and the limiting grooves 706 and the L-shaped plates 707 are convenient for locating the position of the grooves 704, and then convenient for connecting the mud discharge pipe 5 with the connecting pipe 6. The arc surface of the connecting pipe 6 is fixedly connected with two sealing rings 708, and the sealing rings 708 are hollow inside, and the connecting pipe 6 will drive the sealing rings 708 to slide along the inner wall of the groove 704 when it moves, and the sealing rings 708 will be squeezed and deformed by the inner wall of the circular groove 702 when it moves, and the sealing rings 708 can improve the airtightness of the connection between the connecting pipe 6 and the mud discharge pipe 5. The arc surface of the mud discharge pipe 5 is slidably connected with a first clamping ring 709, and the arc surface of the mud discharge pipe 5 is slidably connected with a second clamping ring 710. Two bolts 711 are threaded through the surfaces of the first clamping ring 709 and the second clamping ring 710. The arc surface of the first clamping ring 709 is fixedly connected with two support rods 712. The ends of the two support rods 712 away from the first clamping ring 709 are fixedly connected with an arc plate 713. The connecting pipe 6 is placed on the surface of the arc plate 713, and the connecting pipe 6 will contact the surface of the arc plate 713. The arc plate 713 reaches the position of supporting the connecting pipe 6, thereby further facilitating the connection of the connecting pipe 6 with the mud discharge pipe 5. The surface of the arc plate 713 is fixedly connected with a plurality of protrusions 714, which are arc blocks. The connecting pipe 6 will slide along the surface of the protrusions 714.

The protective pad 715 can prevent the first clamping ring 709 and the second clamping ring 710 from being worn when clamped on the surface of the mud discharge pipe 5.

[0030] Working principle: when the sludge in the sedimentation tank 1 needs to be discharged into the reactor, the connecting pipe 6 needs to be connected to the sludge discharge pipe 5. First, turn the bolt 711. The bolt 711 will move in the first clamping ring 709 and the second clamping ring 710 with the help of the thread. When the bolt 711 moves to a suitable position, pull the first clamping ring 709 and the second clamping ring 710. The first clamping ring 709 and the second clamping ring 710 will slide along the arc surface of the sludge discharge pipe 5. When the first clamping ring 709 moves, it will drive the support rod 712 to move. The movement of the support rod 712 will drive the arc plate 713 to move. When the arc plate 713 moves to a suitable position, turn the bolt 711 in the opposite direction. The bolt 711 will drive The first clamping ring 709 and the second clamping ring 710 move towards each other until the first clamping ring 709 and the second clamping ring 710 drive the protective pad 715 to fit tightly on the arc surface of the mud discharge pipe 5, and the protective pad 715 can prevent the first clamping ring 709 and the second clamping ring 710 from being worn on the surface of the mud discharge pipe 5. Then the connecting pipe 6 is placed on the surface of the arc plate 713, and the connecting pipe 6 will contact the protrusion 714 on the surface of the arc plate 713. Then the connecting pipe 6 is pushed, and the connecting pipe 6 will slide along the surface of the protrusion 714.

The limiting groove 706 and the L-shaped plate 707 reach a position that is convenient for positioning the groove 704, thereby facilitating the connection of the mud discharge pipe 5 with the connecting pipe 6. When the connecting pipe 6 moves, it will drive the sealing ring 708 to slide along the inner wall of the groove 704. When moving, the sealing ring 708 will be squeezed and deformed by the inner wall of the circular groove 702. The sealing ring 708 can improve the airtightness of the connection between the connecting pipe 6 and the mud discharge pipe 5. When the connecting pipe 6 moves to a suitable position, the threaded rod 701 is rotated, and the screw The rotation of the threaded rod 701 will move in the mud discharge pipe 5 with the help of the thread. When the threaded rod 701 moves, it will drive the block 703 to move. The block 703 will move toward the direction close to the connecting pipe 6.

The limiting rod 705 reaches the limit of the moving path of the block 703, thereby preventing the block 703 from rotating during movement. When the block 703 moves to a suitable position, it will slide with the inner wall of the groove 704 until the block 703 completely slides into the groove 704. The block 703 reaches the position to limit the connecting pipe 6, thereby facilitating the connection of the connecting pipe 6 with the mud discharge pipe 5.
