Technical Field

The present invention relates to the technical field of sewage treatment, in particular to an integrated multi-stage sewage treatment device.

Background Art

Before sewage is recycled or discharged, it needs to be treated to meet certain reuse standards or discharge standards to avoid wasting water resources or polluting the environment. When sewage is treated, multiple filter structures are generally used to perform multi-stage filtration treatment on the sewage. However, after working for a period of time, a lot of impurities will accumulate on the filter, which needs to be cleaned before it can continue to work. The filter is generally located inside the treatment equipment, which makes cleaning inconvenient.

The patent publication number is CN215365166U, which is a sewage multi-stage filtration integrated treatment equipment. Its structure mainly includes a bearing ring plate, a support ring plate and four stabilizing rods. A multi-stage sewage treatment mechanism is arranged between the bearing ring plate and the support ring plate. The multi-stage sewage treatment mechanism includes four groups of sewage treatment tanks. A telescopic support member is arranged between two adjacent groups of sewage treatment tanks, and a filtering mechanism is arranged in the inner cavity of the sewage treatment tank. The sewage is subjected to multi-stage filtration treatment by the four groups of sewage treatment tanks, thereby reducing the residual impurities and foreign bodies of different sizes in the sewage, and the four groups of sewage treatment tanks are separated by the telescopic support member so as to clean the impurities therein.

However, when the above-mentioned equipment is cleaning impurities, the equipment needs to be stopped before cleaning can be carried out, which causes the cleaning work and the filtering work to affect each other, thereby affecting the working efficiency of the equipment, etc., and when cleaning, it is necessary to manually clean the four groups of sewage treatment tanks one by one, which is inconvenient.

DETAILED DESCRIPTION

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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Embodiment 1

Please refer to the accompanying drawings, the present invention provides a technical solution:

An integrated multi-stage sewage treatment device includes a treatment box 100, wherein three water inlet pipes 204 are arranged on the top surface of the treatment box 100, a dosing pipe 107 is arranged in the middle of the side wall, and a vertical drain pipe 104 is arranged in the middle of the bottom, and valves are arranged in the water inlet pipe 204, the dosing pipe 107 and the drain pipe 104;

A coarse filter assembly is fixed above the treatment box 100, and the top ends of the three water inlet pipes 204 are fixedly connected to the bottom of the coarse filter assembly;

A rotating assembly 300 is provided at the upper part of the inner cavity of the treatment box 100, and a stirring assembly is provided at the lower part of the inner cavity. Four filtering mechanisms are evenly fixed in the rotating assembly 300 along the circumferential direction. A collecting trough 102 is provided on the inner side wall of the treatment box 100 at a position corresponding to the lower part of one of the filtering mechanisms. The tops of the other three filtering mechanisms are connected to three water inlet pipes 204 at corresponding positions. A notch is provided at a position of the treatment box 100 corresponding to the collecting trough 102, and a cover plate 103 is detachably connected to the notch.

The filtering mechanism includes a horizontal rotating cross plate 304 fixed in the rotating assembly 300, and the middle of the rotating cross plate 304 is connected to the first filter assembly 400 through a spring. The bottom end of the water inlet pipe 204 is correspondingly connected to the top of the first filter assembly 400, and a second filter assembly 500 is provided at the bottom of the first filter assembly 400. Both sides of the second filter assembly 500 are connected to the rotating cross plate 304 through a lifting assembly. The second filter assembly 500 is provided with a flip structure at one end close to the side wall of the treatment box 100, and a limiting structure at the other end.

When treating sewage, the sewage is transported to the treatment equipment through an external conveying device, etc., and the sewage is primarily filtered through a coarse filter component, and then enters the corresponding three filtering mechanisms through three water inlet pipes 204, so that the sewage can be multi-stage filtered through the first filter component 400 and the second filter component 500 to improve the filtering effect. The sewage is then located at the bottom of the treatment box 100, and sewage treatment agents are added to the treatment box 100 through the dosing pipe 107, and stirred and mixed through the stirring component, thereby accelerating the sewage treatment and reaction speed, and realizing multi-stage filtration and chemical treatment in the treatment box 100. After the treatment is completed, the treated sewage is discharged through the drain pipe 104.

After working for a period of time, the coarse filter assembly on the top of the processing box 100 can be cleaned to avoid clogging inside the coarse filter assembly.

When switching the position of the filter mechanism, the second filter assembly 500 is moved downward by the lifting assembly, and the first filter assembly 400 is moved downward accordingly under the action of the spring and is separated from the water inlet pipe 204, so that the positions of the four filter mechanisms are switched by the rotating assembly 300, each time rotating 90°. After switching the positions, the first filter assembly 400 and the second filter assembly 500 at the water inlet pipe 204 are moved back to their positions and connected to the water inlet pipe 204 to continue filtering.

When the filter mechanism passes through the three water inlet pipes 204 in sequence and accumulates a lot of impurities inside, it switches position again and moves to the aggregate trough 102. Then the second filter component 500 moves down and disengages from the first filter component 400, so that the impurities in the first filter component 400 can directly fall into the second filter component 500, and leave enough space between the first filter component 400 and the second filter component 500 so that the second filter component 500 can be turned downward, so that the impurities in the second filter component 500 fall into the aggregate trough 102, completing the impurity cleaning of the filter mechanism without manual cleaning one by one, and the other three filter mechanisms are still filtering normally, so that the cleaning work and filtering work can be carried out simultaneously, thereby improving the sewage treatment efficiency.

Among them, the rotating component 300 includes a fixed table 301 fixed to the upper part of the inner cavity of the processing box 100, and a circular groove is provided in the fixed table 301, in which a first ring table 302 is rotatably connected, a rotating ring gear 303 is fixed to the outer side of the first ring table 302, and the bottom of the rotating gear 307 is in sliding contact with the top of the fixed table 301, and a rotating gear 307 is meshed on one side of the rotating ring gear 303, the rotating gear 307 is rotatably connected to the fixed table 301, and is connected to a motor, and the motor is connected to the fixed table 301, a fixed column 101 is provided at the upper center of the processing box 100, and the upper part of the fixed column 101 is rotatably connected to the second ring table 305, and the two ends of the four rotating horizontal plates 304 are fixedly connected to the first ring table 302 and the second ring table 305 respectively.

When the positions of the four filtering mechanisms need to be switched, the rotating gear 307 is driven by a motor, and the first ring platform 302 drives the four rotating transverse plates 304 and the first filter assembly 400 and the second filter assembly 500 thereon to rotate and switch positions through the transmission of the rotating gear 307 and the rotating ring gear 303. The position stability of the first ring platform 302 is improved by making the rotating ring gear 303 slide in contact with the top of the fixed platform 301. The second ring platform 305 is provided on the fixed column 101 and connected to the inner end of the rotating transverse plate 304 to improve the position stability of the inner end of the four rotating transverse plates 304, thereby improving the position stability of the filtering mechanism.

Among them, the first filter component 400 includes a vertical movable tube 404 slidably connected to the center of the rotating horizontal plate 304, the bottom ends of the three water inlet pipes 204 are slidably connected to the three movable tubes 404 at corresponding positions, and an annular spring plate 405 is fixed to the outer side of the top end of the movable tube 404, the bottom of the spring plate 405 is connected to the rotating horizontal plate 304 through a spring, and vertical sliding shafts 406 are symmetrically fixed on both sides of the bottom of the spring plate 405, the bottom end of the sliding shaft 406 passes through the rotating horizontal plate 304, and is jointly fixed with an annular end plate 401, and the bottom end of the movable tube 404 is fixed at the center of the end plate 401, a vertical first filter screen cylinder 402 is fixed to the inner side of the bottom of the end plate 401, and a vertical second filter screen cylinder 403 is fixed to the outer side of the bottom, and the bottom ends of the first filter screen cylinder 402 and the second filter screen cylinder 403 are both connected to the second filter component 500 accordingly.

After the sewage is initially filtered by the coarse filter assembly, it enters the mobile pipe 404 at the corresponding position through the water inlet pipe 204. The bottom ends of the first filter screen cylinder 402 and the second filter screen cylinder 403 are sealed by the corresponding structure in the second filter assembly 500, so that after the sewage enters the first filter screen cylinder 402, it is subjected to secondary filtering treatment by the first filter screen cylinder 402 and the second filter screen cylinder 403, thereby improving the filtering effect, and the filtered sewage is discharged into the second filter assembly 500 for further filtering treatment;

When the lifting assembly drives the second filter assembly 500 to move downward, structures such as the spring plate 405 and the end plate 401 move downward accordingly under the action of the spring, so that the movable tube 404 is separated from the water inlet pipe 204, so as to switch the positions of the four filtering mechanisms, and when the second filter assembly 500 continues to move downward, the bottom ends of the first filter mesh cylinder 402 and the second filter mesh cylinder 403 are separated from the second filter assembly 500, so that the impurities accumulated in the first filter mesh cylinder 402 and the second filter mesh cylinder 403 move downward and fall into the second filter assembly 500, so that they can be discharged together with the impurities in the second filter assembly 500 when the second filter assembly 500 is flipped later.

Among them, the second filter component 500 includes a circular filter tank 501, an annular filter screen 502 is fixed at the bottom of the inner cavity of the filter tank 501, a circular sealing plate 503 is fixed at the center of the arc filter screen, and the bottom ends of the first filter screen cylinder 402 and the second filter screen cylinder 403 are in contact with the top surface of the sealing plate 503, and two flip shafts 504 are symmetrically fixed on both sides of the filter tank 501, a lifting component is provided on the rotating horizontal plate 304, and the flip shaft 504 is rotatably connected to the lifting component, a flip shaft 504 close to the side wall of the processing box 100 is connected to the flip structure, and the other flip shaft 504 is connected to the limiting structure.

After the sewage is filtered by the first filter screen cylinder 402 and the second filter screen cylinder 403, it enters the interior of the filter tank 501 and is filtered again by the annular filter screen 502 to further improve the filtering effect. When it is necessary to switch the positions of the four filtering mechanisms, the filter tank 501 is moved down by the lifting component, and the first filtering component 400 is moved down a distance under the action of the spring, so that the bottom end of the water inlet pipe 204 is separated from the moving pipe 404, so that the positions of the four filtering mechanisms can be switched by the rotating component 300;

When the filter mechanism moves to the aggregate trough 102, the lifting assembly drives the filter trough 501 to continue to move downward, so that the filter trough 501 is free from the restriction of the limiting structure and leaves enough space under the first filter assembly 400, and then the filter trough 501 is flipped downward by the flipping structure, so that impurities in the filter trough 501 are cleaned into the aggregate trough 102, and then the filter trough 501 is flipped upward and re-limited by the limiting structure, so that the filter trough 501 remains in an upward state and does not rotate at will, and moves back to its original position by the lifting assembly, so that the first filter assembly 400 and the second filter assembly 500 remain connected, and the bottom ends of the first filter screen cylinder 402 and the second filter screen cylinder 403 are closed to continue switching positions and participate in the filtering work.

Among them, the lifting assembly includes two vertical lifting rods 508, and the bottom end of the lifting rod 508 is fixed with a mounting tube 507, and the two flip shafts 504 are respectively rotatably connected to the mounting tube 507 on the corresponding side to realize the rotational connection between the filter tank 501 and the lifting assembly. The top of the lifting rod 508 passes through the rotating horizontal plate 304 and is slidably connected with the rotating horizontal plate 304 along the vertical direction. The lifting rod 508 is provided with a vertical groove, and a plurality of teeth are evenly fixed in the vertical groove, and a lifting gear 509 is meshed with the teeth. The lifting gear 509 is rotatably connected to the bottom of the rotating horizontal plate 304 and is connected to a motor, and the motor is fixed on the rotating horizontal plate 304. The lifting gear 509 is rotated by the motor, and through the action of the lifting gear 509 and the teeth, the lifting rod 508 drives the filter tank 501 and other structures to move.

Among them, the flipping structure includes a bevel gear 505, and the bevel gear 505 is fixed to the end of the flipping shaft 504 close to the side wall of the processing box 100, and an arc-shaped bevel rack 510 is fixed on the inner wall of the processing box 100 at a position above the collecting trough 102, and the bevel gear 505 is correspondingly connected to the arc-shaped bevel rack 510.

When the filter tank 501 rotates to the aggregate tank 102 and moves downward to disengage from the limiting structure, the bevel gear 505 contacts the arcuate bevel rack 510, and under the continued rotation of the rotating assembly 300 and the rotating cross plate 304 and other structures, the bevel gear 505 rotates along the arcuate bevel rack 510, thereby driving the flip shaft 504 and the filter tank 501 to rotate downward. At this time, the rotating assembly 300 stops rotating, and impurities in the filter tank 501 fall into the aggregate tank 102, so that the impurities in the filter tank 501 are cleaned. When the rotating assembly 300 continues to rotate and switches the positions of the four filtering mechanisms, the bevel gear 505 continues to rotate along the arcuate bevel rack 510, so that the opening of the filter tank 501 faces upward. At this time, the bevel gear 505 disengages from the arcuate bevel rack 510 and is re-limited by the limiting structure, so that the filter tank 501 remains in an upward state for subsequent filtering work.

Among them, the limiting structure includes a limiting block 506, which is fixed at the end of the flip axis 504 away from the side wall of the processing box 100, and a limiting hole is provided on the limiting block 506. Four vertical limiting shafts 306 are evenly fixed along the circumferential direction at the bottom of the second ring platform 305, and the limiting shafts 306 pass through the limiting holes at the corresponding positions and are connected with the limiting sliding.

When the filter tank 501 starts to move downward, the limit block 506 moves downward along the limit shaft 306. Through the action of the limit block 506 and the limit shaft 306, the filter tank 501 remains in an open upward state. When the bevel gear 505 is about to reach the position of the arcuate bevel rack 510, the filter tank 501 and the limit block 506 move downward under the action of the lifting assembly. When the limit block 506 disengages from the limit shaft 306, the bevel gear 505 contacts the arcuate bevel rack 510, so that the filter tank 501 is flipped over by the bevel gear 505 and the arcuate bevel rack 510 during subsequent movement. When the filter tank 501 is cleaned and flipped upward, the lifting assembly drives the filter tank 501 and the limit block 506 to move upward, the bevel gear 505 disengages from the arcuate bevel rack 510, and the limit block 506 is connected to the limit shaft 306, so that the filter tank 501 is limited again for subsequent filtering work.
