Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a sludge removal system for a flocculation tank used in tap water treatment. Background Technology

[0002] A flocculation tank is a water purification tank where the flocculation process is completed. It creates suitable hydraulic conditions for particles with flocculation properties to aggregate through contact, forming larger flocs. It plays a crucial role in water purification. Suspended and solid substances in natural water have very small particle sizes. To remove these substances, coagulation is usually employed. This involves adding an appropriate coagulant to the raw water, thoroughly mixing it, destabilizing the colloidal particles, and adsorbing them onto the polymer phase of the coagulant in the water, thus giving the particles flocculation properties. The purpose of a flocculation tank is to create suitable hydraulic conditions for these flocculating particles to aggregate through contact, forming larger flocs.

[0003] Flocculation tanks are often used in combination with sludge discharge tanks. Several sludge discharge pipes installed at the bottom of the flocculation tank, along with a vacuum pump, transfer the sludge settled at the bottom of the flocculation tank to the sludge discharge tank for further sludge treatment. When the existing sludge discharge system discharges the sludge from the bottom of the flocculation tank through the sludge discharge pipes, it often carries away some unprecipitated water from the flocculation tank. This water often contains a large number of flocs that have not formed sediment. If it directly follows the sludge into the next treatment process, the purification will not be thorough enough, and it urgently needs to be improved. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a sludge removal system for a flocculation tank in tap water treatment. The system includes a flocculation tank, a sludge removal tank, and several sludge removal pipes equipped with a vacuum pump. All sludge removal pipes are located at the bottom of the flocculation tank, with one end open inside the sludge removal tank. A circulation tank is located on one side of the sludge removal tank, and a circulation device is provided on the circulation tank. The circulation device includes a pair of mounting rods, a water suction transfer plate, a rotary motor, a circulating water pump, several circulating water pipes, and a squeezing mechanism. The pair of mounting rods are fixedly mounted on the side walls adjacent to the circulation tank and the sludge removal tank. The rotary motor is located on one side of the mounting rods. The water suction transfer plate is rotatably connected to the pair of mounting rods, and one end of the water suction transfer plate is connected to the rotary motor. The circulating water pump is connected to the circulation tank and the flocculation tank respectively through several circulating water pipes. The squeezing mechanism includes a mounting plate, a drive cylinder, and a squeezing plate. The mounting plate is fixedly mounted on the edge of the circulation tank, the drive cylinder is mounted on the mounting plate, and the squeezing plate is fixedly connected to the piston rod of the drive cylinder.

[0005] Using the above technical solution, a circulation tank is set up on one side of the sludge discharge tank. At the same time, the sludge with some sewage at the bottom of the flocculation tank is discharged into the sludge discharge tank through the sludge discharge pipe. The circulation device on the circulation tank operates simultaneously. A rotating motor drives the water suction transfer plate to rotate back and forth in the sludge discharge tank and the circulation tank. The water that has not settled in the sludge discharge tank is adsorbed onto the water suction transfer plate, and then rotates to the wall of the circulation tank. At this time, the extrusion mechanism is activated. The extrusion plate is controlled by the drive cylinder to squeeze the water suction transfer plate attached to the wall of the tank, squeezing out the water it carries and letting it flow into the circulation tank. The water in the circulation tank is then periodically pumped back into the flocculation tank through the circulation water pump and circulation water pipe for further sedimentation, so that the water in the flocculation tank can settle as much as possible and the purification effect is better.

[0006] A further feature of this invention is that the water-absorbing transfer plate includes a connector and an absorbent sponge, and the connector and the absorbent sponge are detachably connected.

[0007] By adopting the above technical solution, since the water-absorbing transfer plate includes a connector and a water-absorbing sponge, and the connector is detachably connected to the water-absorbing sponge, the water-absorbing sponge can be replaced regularly to avoid the water-absorbing sponge losing its elasticity due to repeated squeezing.

[0008] A further feature of this invention is that the pair of mounting rods are also provided with a protective cover for preventing splashes. The protective cover includes a cover body and several mounting supports, and the cover body is connected to the pair of mounting rods through several mounting supports.

[0009] By adopting the above technical solution, since the pair of mounting rods are also provided with a protective cover for preventing splashing, the protective cover includes a cover body and several mounting supports. The cover body is connected to the pair of mounting rods through several mounting supports. The splash cover prevents sewage splashing that may occur during the rotation of the water absorption transfer plate.

[0010] A further feature of this invention is that a pair of mounting beams are symmetrically arranged on both sides of the circulation pool, and a filter tray is provided on the mounting beams.

[0011] By adopting the above technical solution, since a pair of mounting beams are symmetrically arranged on the two side walls of the circulation tank, and a filter tray is provided on the mounting beam, the sewage squeezed down from the absorbent sponge can pass through the filter tray and flow into the circulation tank, thereby minimizing the situation where sludge is recycled back into the flocculation tank.

Detailed Implementation

[0015] like Figure 1-2 The illustrated sludge removal system for a flocculation tank in tap water treatment includes a flocculation tank 1, a sludge removal tank 2, and several sludge removal pipes 3 equipped with a vacuum pump. All sludge removal pipes are located at the bottom of the flocculation tank with one end open inside the sludge removal tank. A circulation tank 4 is located on one side of the sludge removal tank, and a circulation device 5 is provided on the circulation tank. The circulation device includes a pair of mounting rods 6, a water suction transfer plate 7, a rotary motor 8, a circulating water pump 9, several circulating water pipes 10, and a squeezing mechanism 11. The pair of mounting rods are fixedly mounted on the side walls adjacent to the circulation tank and the sludge removal tank. The rotary motor is located on one side of the mounting rods. The water suction transfer plate is rotatably connected to the pair of mounting rods, and one end of the water suction transfer plate is connected to the rotary motor. The circulating water pump is connected to the circulation tank and the flocculation tank respectively through several circulating water pipes. The squeezing mechanism includes a mounting plate 12, a drive cylinder 13, and a squeezing plate 14. The mounting plate is fixedly mounted on the edge of the circulation tank, the drive cylinder is mounted on the mounting plate, and the squeezing plate is fixedly connected to the piston rod of the drive cylinder.

[0016] A circulation tank is set up on one side of the sludge discharge tank. Sludge with some sewage at the bottom of the flocculation tank is discharged into the sludge discharge tank through the sludge discharge pipe. At the same time, the circulation device on the circulation tank operates. A rotating motor drives the suction transfer plate to rotate back and forth in the sludge discharge tank and the circulation tank. The sewage in the sludge discharge tank is adsorbed onto the suction transfer plate, and then rotated to the wall of the circulation tank. At this time, the extrusion mechanism is activated. The extrusion plate is controlled by the drive cylinder to squeeze the suction transfer plate attached to the wall of the tank, squeezing out the sewage it carries and letting it flow into the circulation tank. The sewage in the circulation tank is then periodically pumped back to the flocculation tank by the circulating water pump and circulating water pipe for further sedimentation. This allows the sewage in the flocculation tank to settle as much as possible, reducing the environmental impact caused by direct discharge due to incomplete sedimentation.

[0017] The water-absorbing transfer plate includes a connector 15 and a water-absorbing sponge 16, and the connector is detachably connected to the water-absorbing sponge.

[0018] Since the water-absorbing transfer plate includes a connector and a water-absorbing sponge, and the connector is detachably connected to the water-absorbing sponge, the water-absorbing sponge can be replaced periodically to avoid the water-absorbing sponge losing its elasticity due to repeated squeezing.

[0019] The pair of mounting rods are also provided with a protective cover 17 for preventing splashes. The protective cover includes a cover body 18 and a plurality of mounting supports 19. The cover body is connected to the pair of mounting rods through the plurality of mounting supports.

[0020] The pair of mounting rods are also equipped with a protective cover for preventing splashing. The protective cover includes a cover body and several mounting supports. The cover body is connected to the pair of mounting rods through several mounting supports. The splash cover prevents sewage splashing that may occur during the rotation of the water absorption transfer plate.

[0021] A pair of mounting beams 20 are symmetrically arranged on both sides of the circulation pool, and a filter tray 21 is provided on the mounting beam.

[0022] Because a pair of mounting beams are symmetrically arranged on the two side walls of the circulation tank, and a filter tray is provided on the mounting beam, the sewage squeezed down from the absorbent sponge can pass through the filter tray and flow into the circulation tank, thus minimizing the situation where sludge is recycled back into the flocculation tank.
