Description

A sewage treatment equipment

Technical Field

The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment.

Background technique

Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

Existing sewage treatment equipment includes screen machines, sewage treatment tanks, sedimentation tanks and multi-core backwash precision filters. The multi-core precision filter is composed of a stainless steel shell and a filter element. It is a widely used filter device in industry. The raw water passes through the filter element from the outside to the inside, gathers together and flows out from the center. The granular impurities in the raw water are trapped on the surface of the filter element, thereby achieving the purpose of filtration and purification.

The existing multi-core backwash precision filter needs to start the backwash system to flush the inner wall of the filter element when the filter element is blocked during use. However, when the filter element is in use, the sediment in the sewage is usually close to the bottom of the sewage, and the lower half of the filter element is blocked by the particles in the sewage to a greater extent and with greater blocking force. The impact force on the surface of the filter element during backwashing is the same, and the blockage in the lower half of the filter element is not easy to be flushed out. Long-term use of the filter element will cause the filter element to be blocked, and the filter element needs to be replaced, which affects the service life of the filter element. To this end, we propose a sewage treatment device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 9, the present invention provides a technical solution:

Example 1

A sewage treatment device, comprising: a body 001;

Also includes;

The conditioning chamber 002 is arranged at the lower side of the machine body 001;

Treatment chamber 003, which is disposed on the upper side of the body 001 and is used to treat sewage;

Filter cartridge 004, filter cartridge 004 is arranged inside treatment chamber 003, and filter cartridge 004 is used to filter sewage;

An adjusting component 005 is disposed inside the processing chamber 003 and rotates according to the position of the filter cartridge 004;

The filter assembly 006 is arranged inside the filter cartridge 004. After the adjustment assembly 005 rotates to the bottom of the filter cartridge 004 that needs to be cleaned, the filter assembly 006 docks the filter cartridge 004 with the adjustment assembly 005, so that the filter cartridge 004 is cleaned gradually upward along the inner wall of the bottom of the cartridge.

Sewage enters the regulating chamber 002 through the water inlet pipe 210, and enters the treatment chamber 003 through the filter cartridge 004 under water pressure. The filter cartridge 004 intercepts impurities such as particles and suspended matter in the sewage on the inner wall of the filter cartridge 004, and the filtered water flows into the outside through the outlet pipe 220. The staff can further process the filtered water. After the device has been used for a certain period of time, solid particles are intercepted inside the filter cartridge 004, and the filtering pressure of the filter cartridge 004 increases. The controller 250 detects that the pressure difference between the regulating chamber 002 and the treatment chamber 003 is too large, and the adjustment component 005 will be started to gradually adjust and align the adjustment component 005 with respect to the position of the filter cartridge 004. The inside of the filter cartridge 004 begins to recoil, so that the impurities inside the filter cartridge 004 enter the sewage pipe 520 through the flushing arm 506. At the same time, the filter component 006 is started, so that the turbulence fan 602 slides inside the filter cartridge 004, thereby increasing the recoil speed of the filter cartridge 004 and further improving the cleaning efficiency of the filter cartridge 004.

One side of the regulating chamber 002 is connected to a water inlet pipe 210, and the other side of the processing chamber 003 is connected to a water outlet pipe 220. Valves 230 are installed on the outer walls of the water inlet pipe 210 and the water outlet pipe 220. A balancing pipe 240 is arranged between the regulating chamber 002 and the processing chamber 003, and a controller 250 is installed on the outer wall of the balancing pipe 240.

There are multiple filter cartridges 004 , which are symmetrically distributed about the processing chamber 003 . The bottom end of the filter cartridge 004 is fixedly connected with a fixing plate 410 , and the filter cartridge 004 is connected to the regulating chamber 002 through the fixing plate 410 .

The controller 250 can detect the water pressure difference between the regulating chamber 002 and the processing chamber 003. If the pressure difference is too large, the reduction motor 501 can be controlled to start, so that the reduction motor 501 drives the regulating component 005 to clean the filter cartridges 004 one by one.

The adjusting component 005 includes a reduction motor 501, the top of which is fixedly connected to a first fixed rod 502, the top of which is fixedly connected to a first transmission gear 503, one side of the first transmission gear 503 is meshingly connected to a second transmission gear 504, the top of the second transmission gear 504 is fixedly connected to a connecting pipe 505, the connecting pipe 505 is rotatably connected to the body 001, the top of the connecting pipe 505 is fixedly connected to a flushing arm 506, the shape of the flushing arm 506 is set to be a "丩" shape, the top of the flushing arm 506 passes through the fixed plate 410, the flushing arm 506 is rotatably connected to the body 001, one side of the flushing arm 506 is fixedly connected to a buffer cylinder 507, a pressure sensor 508 is set above the buffer cylinder 507, the pressure sensor 508 is fixedly connected to the filter cylinder 004, the pressure sensor 508 is set on the outside of the filter cylinder 004, and the buffer cylinder 507 is connected to the filter cylinder 004.

The reduction motor 501 mobilizes the first fixed rod 502 to rotate, and through the mutual cooperation of the first transmission gear 503 and the second transmission gear 504, the lateral rotation of the first fixed rod 502 is converted into the longitudinal rotation of the flushing arm 506. When the buffer cylinder 507 reaches the bottom of the filter cylinder 004 and the buffer cylinder 507 presses on the pressure sensor 508, the flushing arm 506 is located at the bottom of the filter cylinder 004. At the same time, the flushing arm 506 is aligned with the filter cylinder 004, and a pressure difference is formed between the filter cylinder 004 and the flushing arm 506. The water outside the filter cylinder 004 backwashes and flushes the impurities inside the flushing arm 506 downward to the inside of the flushing arm 506 until the sewage pipe 520 discharges the impurities to the outside. At the same time, after the pressure sensor 508 senses the position of the flushing arm 506, it can control the reduction motor 501 and the sewage valve 530 to open at the same time, which is convenient for the discharge of impurities. The filter cylinder 004 can be cleaned continuously without hindering the continued operation of the device.

The transmission assembly 007 is arranged inside the buffer cylinder 507, and a sealing ring 510 is arranged at the top of the buffer cylinder 507. The top of the sealing ring 510 is tightly attached to the bottom of the fixing plate 410, and the sealing ring 510 is made of silicone.

The provision of the sealing ring 510 facilitates the rapid connection between the flushing arm 506 and the filter cartridge 004 and prevents particles from leaking to the outside through the connection port, which would result in a poor cleaning effect.

The flushing arm 506 is rotatably connected to the fixed plate 410 , and a drain pipe 520 is movably connected to the top of the flushing arm 506 . The drain pipe 520 extends to the outside of the machine body 001 , and a drain valve 530 is installed on the outer wall of the drain pipe 520 .

The filter assembly 006 includes a lifting rod 601, the top outer wall of the lifting rod 601 is threadedly connected to a spoiler fan 602, the outer wall of the spoiler fan 602 is fixedly connected to a positioning ring 603, the front and rear ends of the positioning ring 603 are provided with positioning grooves 604, the interior of the positioning grooves 604 is provided with a mosaic plate 605, the bottom end of the mosaic plate 605 is fixedly connected to a sliding hook 606, the rear end of the mosaic plate 605 is fixedly connected to a plurality of telescopic rods 607 at equal intervals, the rear end of the telescopic rod 607 is slidably connected to a positioning shell 608, and the interior of the positioning shell 608 is provided with a return spring 609.

The transmission assembly 007 includes a stepper motor 701, the top of which is fixedly connected to a second fixed rod 702, the second fixed rod 702 and the connecting tube 505 are on the same vertical line, the second fixed rod 702 passes through the second transmission gear 504, a first connecting rod 703 is provided on one side of the second fixed rod 702, both ends of the first connecting rod 703 are fixedly connected to the first connecting gear 704, the sides of the first connecting gear 704 are meshedly connected to the second connecting gear 705, the second connecting gear 705 is fixedly connected to the second fixed rod 702, and the rear end of the first connecting gear 704 is fixedly connected to the second connecting rod 706, the top of the second connecting rod 706 is fixedly connected to a screw rod 707, the outer wall of the screw rod 707 is threadedly connected to a movable rod 708, and the top of the movable rod 708 is provided with a lifting frame 709.

The top of the lifting frame 709 is fixedly connected to the brake frame 710, and the brake plate 720 is meshedly connected inside the brake frame 710. The brake plate 720 is fixedly connected to the lifting rod 601. The two ends of the lifting frame 709 are fixedly connected to the brake rod 730, and the outer wall of the brake rod 730 and the outer surface of the sliding hook 606 are both inclined.

The pressure sensor 508 can control the stepper motor 701 to start, so that it drives the second fixed rod 702 to rotate. Through the mutual cooperation of the first connecting gear 704 and the second connecting gear 705 on both sides of the first connecting rod 703, the second fixed rod 702 drives the second connecting rod 706 to rotate. At the same time, the second connecting rod 706 drives the screw rod 707 to rotate, and then the movable rod 708 and the lifting frame 709 rise and fall inside the buffer cylinder 507.

After the lifting frame 709 is raised, the brake frame 710 is automatically aligned with the brake plate 720 at the bottom of the lifting rod 601, and the stepper motor 701 drives the lifting rod 601 to rotate continuously through the brake frame 710, and then the spoiler fan 602 threadedly connected to the lifting rod 601 rises inside the lifting rod 601. During the rising process of the spoiler fan 602, the liquid pressure difference between the filter cartridge 004 and the flushing arm 506 is increased, the recoil speed is increased, and the stubborn particulate impurities at the bottom of the filter cartridge 004 are cleaned, so that the inside of the filter cartridge 004 is fully cleaned, the filtering effect of the filter cartridge 004 is improved, and the service life of the filter cartridge 004 is extended.

After the lifting frame 709 is raised, the brake rods 730 on both sides of the lifting frame 709 are automatically aligned with the sliding hooks 606. During the rising process, the brake rods 730 cause the sliding hooks 606 to gradually move toward the direction of the positioning groove 604 along the inclined direction, and then the interlocking plate 605 is embedded in the positioning groove 604, so that the spoiler fan 602 moves along the direction of the interlocking plate 605.

Example 2

In this embodiment 2, other structures remain unchanged. The difference from embodiment 1 is that a plurality of sliders 740 are fixedly connected to the outer wall annular array of the lifting frame 709. The sliders 740 are slidably connected to the buffer cylinder 507. The top of the sliders 740 is fixedly connected to a buffer spring 750.

Among them, when a filter cartridge 004 is filtered, the controller 250 drives the reduction motor 501 to continue to start, and then the flushing arm 506 starts to rotate. When the flushing arm 506 rotates, the first connecting rod 703 rotates accordingly, and the first connecting gear 704 on the side of the second connecting rod 706 cooperates with the second connecting gear 705 to make the second connecting rod 706 rotate in the opposite direction, and then the second connecting rod 706 drives the movable rod 708 to descend on the screw rod 707, so that the lifting frame 709 drives the brake rod 730 and the brake frame 710 to tighten the inside of the buffer cylinder 507 until the slider 740 and the lifting frame 709 reach the bottom of the buffer cylinder 507, so that the flushing arm 506 continues to rotate and ensures the operating stability of the flushing arm 506.

Among them, after the lifting frame 709 is retracted into the buffer cylinder 507, the interlocking plate 605 is retracted into the inner wall of the filter cylinder 004 under the action of the reset spring 609, and the interlocking plate 605 is not connected to the positioning groove 604. After the filter cylinder 004 continues to run, particulate impurities accumulate inside the filter cylinder 004, and the pressure difference inside the filter cylinder 004 gradually increases, and most of the particles accumulate at the bottom of the filter cylinder 004. The pressure difference between the upper and lower parts of the filter cylinder 004 is different. The turbulence fan 602 rotates under the pressure difference and gradually moves downward along the lifting rod 601 until it reaches the bottom of the filter cylinder 004.
