Description

Technical Field

[0001] The present invention relates to the technical field of sewage pretreatment, in particular to an environmentally friendly urban sewage purification pretreatment device. Background Art

[0002] As the primary link in the sewage treatment system, urban sewage pretreatment mainly carries out preliminary separation and removal of the following five types of garbage (large particles of solid waste, suspended matter, oil and grease pollutants, organic particulate matter, inorganic sediments) and pollutants to reduce the subsequent treatment load and protect the safe operation of equipment.

[0003] Urban sewage treatment requires the centralized collection of sewage through the sewer system and its transportation to a unified sewage treatment plant for treatment.

[0004] During urban sewage pretreatment, workers often use handheld scoop nets to fish out fallen leaves, branches, and other debris from the pretreatment fences. Relying solely on manual labor to clear debris clogged at the fences is time-consuming and labor-intensive, and treatment is often delayed, which can easily lead to blockages at sewer entrances. Blockages prevent sewage from draining properly and cause it to backflow into homes through outlets like floor drains and toilets, soaking and damaging floors and furniture. Furthermore, the fermentation of organic matter in the sewage releases harmful gases like hydrogen sulfide, producing a pungent odor. Low-rise residents are particularly susceptible to backflow due to unbalanced pipe pressure, which damages their living environment. Severe blockages require water shutoffs for repairs, resulting in water outages. This reduces daily drainage efficiency, causing sinks and bathrooms to drain more slowly or even become completely unusable.

[0005] Therefore, in order to reduce the frequency of sewer blockage, an environmentally friendly urban sewage purification pretreatment device is proposed. Summary of the Invention

[0006] In order to solve the technical problems raised in the background technology, the present invention provides an environmentally friendly urban sewage purification pretreatment device.

[0008] Among them, an outer filter cylinder is arranged in the cylinder block. The outer filter cylinder and the cylinder block are arranged coaxially with a gap between the two. A filtering mechanism is arranged on the top of the outer filter cylinder. The filtering mechanism can clean the garbage entering it along the grille and clean the garbage to the bottom of the filtering mechanism for collection.

[0009] The lifting mechanism is used to drive the outer filter cartridge to drive the filter mechanism to move vertically.

[0010] As a further improvement of the above scheme, the grille is composed of horizontal section one, inclined section and horizontal section two from top to bottom, among which horizontal section one is closer to the direction of the cylinder block, so that the inclined section and horizontal section two form an obtuse angle, and positioning blocks are provided on both sides of the top of horizontal section one at the connection with the guide frame to ensure the stability of the grille when placed.

[0011] As a further improvement of the above scheme, the filtering mechanism includes an outer filter cartridge, which is coaxially arranged on the upper part of the cartridge block. Two connecting blocks are symmetrically fixedly connected on both sides of the top of the outer filter cartridge. The inner sides of the two connecting blocks are respectively clamped with plug-ins. The inner sides of the two plug-ins are fixedly connected with an inner filter cartridge. Two placement holes are symmetrically opened at the bottom end of the inner filter cartridge. Collection filter cartridges are clamped in the two placement holes. The collection filter cartridge is used to collect garbage and can be quickly disassembled and cleaned. The top of the collection filter cartridge is flush with the bottom of the inner wall of the inner filter cartridge.

[0012] As a further improvement of the above scheme, a connecting concave block is fixedly connected to the middle part of the bottom end of the inner filter cartridge, and the connecting concave block is coaxially arranged with the inner filter cartridge. The top of the connecting concave block is rotatably connected to the bottom rotating block, and the top of the bottom rotating block is fixedly connected to a rotating plate.

The top of the plug plate is fixedly connected to the inner rod, and the top of the inner rod is coaxially fixedly connected to the round block, and the top of the round block is connected to the lifting mechanism.

[0013] As a further improvement of the above scheme, connecting pipes are symmetrically opened on both sides of the bottom end of the movable cavity along the middle of the extension direction of the rotating plate, and the connecting pipes are connected to the outside of the rotating plate, which is used to suck the garbage at the inner filter cylinder when the plug plate slides vertically back and forth, so as to avoid the garbage from blocking the inner filter cylinder.

[0014] As a further improvement of the above scheme, the lifting mechanism includes two hydraulic rods symmetrically fixedly connected to the outer wall of the cylinder block, the top of the telescopic ends of the two hydraulic rods are fixedly connected to a connecting plate, the inner bottom ends of the two connecting plates are fixedly connected to the top of the connecting block, the tops of the two connecting plates are respectively fixedly connected to vertical rods, the tops of the two vertical rods are fixedly connected to a horizontal plate, the bottom end of the horizontal plate is fixedly connected to hydraulic rod 2, the bottom end of hydraulic rod 2 is fixedly connected to the round block, the bottom end of the round block is coaxially fixedly connected to the outer cylinder, the outer cylinder is located on the outside of the inner rod, and the bottom of the inner wall of the outer cylinder is fixedly connected to a round protrusion.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example: Please combine Figure 1-Figure 7 The environmentally friendly urban sewage purification pretreatment device of this embodiment includes a guide frame 1 installed at the sewer outlet, a grille 3 installed on one side of the guide frame 1, and a cylinder block 2 installed at the bottom of the guide frame 1.

[0030] Specifically, the guide frame 1 is set at a height lower than the sewer position to facilitate the sewer water flow to enter the guide frame 1 and undergo preliminary filtration.

[0031] Among them, an outer filter cylinder 4 is arranged in the cylinder block 2. The outer filter cylinder 4 is coaxially arranged with the cylinder block 2 and there is a gap between the two. A filtering mechanism is arranged on the top of the outer filter cylinder 4. The filtering mechanism can clean the garbage entering it along the grille 3 and clean the garbage to the bottom of the filtering mechanism for collection.

[0032] The lifting mechanism is used to drive the outer filter cartridge 4 to drive the filter mechanism to move vertically.

[0033] Specifically, it is used to lift the entire filtering mechanism and easily remove the garbage collected inside, thereby facilitating cleaning.

[0034] The grille 3 is composed of a horizontal section 1, an inclined section and a horizontal section 2 from top to bottom. The horizontal section 1 is closer to the direction of the cylinder block 2, so that the inclined section and the horizontal section 2 form an obtuse angle. Positioning blocks are provided on both sides of the top of the horizontal section 1 at the connection with the guide frame 1 to ensure the stability of the grille 3 when it is placed.

[0035] Specifically, a limiting block is symmetrically arranged on one side of the top of the guide frame 1 near the water inlet, which can be vertically connected with the positioning block at the grille 3 to increase the grille 3's ability to withstand water pressure, and the plastic bags, branches and other garbage blocked by the grille 3 can be quickly removed to clean up.

[0036] The filtering mechanism includes an outer filter cartridge 4, which is coaxially arranged on the upper part of the cartridge block 2. Two connecting blocks 7 are symmetrically fixedly connected to the two sides of the top of the outer filter cartridge 4. The inner sides of the two connecting blocks 7 are respectively clamped with plug-in plates 9. The inner sides of the two plug-in plates 9 are fixedly connected with an inner filter cartridge 8. Two placement holes 10 are symmetrically provided at the bottom end of the inner filter cartridge 8. A collecting filter cartridge 11 is clamped in the two placement holes 10. The collecting filter cartridge 11 is used to collect garbage and can be quickly disassembled and cleaned. The top of the collecting filter cartridge 11 is flush with the bottom of the inner wall of the inner filter cartridge 8.

[0037] Specifically, the collecting filter cartridge 11 is kept flush with the inner filter cartridge 8 to facilitate the cleaning action of the rotating plate 21, and the excess garbage is cleaned into the collecting filter cartridge 11. After the lifting system rises, the rotating plate 21 is rotated to a state where it does not block the collecting filter cartridge 11. The collecting filter cartridge 11 can be quickly taken out and the interior can be cleaned. A sensor is provided on the top of the collecting filter cartridge 11 to sense the height of the collected garbage. When it is higher than the set threshold, an alarm will be issued and a reminder will be given, and the water inlet will be blocked to facilitate cleaning inside.

[0038] The middle part of the bottom end of the inner filter cartridge 8 is fixedly connected to a connecting concave block 12, which is coaxially arranged with the inner filter cartridge 8. The top of the connecting concave block 12 is rotatably connected to the bottom rotating block 26, and the top of the bottom rotating block 26 is fixedly connected to a rotating plate 21. Both sides of the rotating plate 21 are in contact with the inner wall of the inner filter cartridge 8. A movable cavity 24 is provided coaxially with the middle part of the rotating plate 21 and the middle part of the inner filter cartridge 8. A plug plate 18 is vertically slidably connected in the movable cavity 24. A sealing rubber ring is provided on the outer sleeve of the plug plate 18. The top of the plug plate 18 is fixedly connected to the inner rod 17. The top of the inner rod 17 is coaxially fixedly connected to the round block 16, and the top of the round block 16 is connected to the lifting mechanism.

[0039] Specifically, when the plug plate 18 slides back and forth vertically along the movable chamber 24, the plug plate 18 can absorb the garbage or water in the contact area with the inner filter cartridge 8 through the connecting pipe 25 when it rises, and push the medium in the movable chamber 24 to be ejected outward along the connecting pipe 25 when the plug plate 18 descends, so as to clean the garbage that is blocked and adhered to the inner filter cartridge 8.

[0040] Connecting pipes 25 are symmetrically opened on both sides of the bottom end of the movable chamber 24 along the middle of the extension direction of the rotating plate 21, and the connecting pipes 25 are connected to the outer side of the rotating plate 21, and are used to suck the garbage at the inner filter cylinder 8 when the plug plate 18 slides vertically back and forth, so as to prevent the garbage from blocking the inner filter cylinder 8, wherein the bottom end of the inner filter cylinder 8 has a hole only at the hole 10.

[0041] Specifically, grooves are symmetrically provided on both sides of the rotating plate 21 , and elastic rubber is provided on the periphery of the connecting pipe 25 to concentrate the force when the connecting pipe 25 is sucked.

[0042] The lifting mechanism includes two hydraulic rods 5 symmetrically fixedly connected to the outer wall of the cylinder block 2, the top of the telescopic ends of the two hydraulic rods 5 are fixedly connected to a connecting plate 6, the inner bottom ends of the two connecting plates 6 are fixedly connected to the top of the connecting block 7, the tops of the two connecting plates 6 are respectively fixedly connected to vertical rods 13, the tops of the two vertical rods 13 are fixedly connected to a horizontal plate 14, the bottom end of the horizontal plate 14 is fixedly connected to a hydraulic rod 2 15, the bottom end of the hydraulic rod 2 15 is fixedly connected to the round block 16, the bottom end of the round block 16 is coaxially fixedly connected to the outer cylinder 19, the outer cylinder 19 is located on the outside of the inner rod 17, and the bottom of the inner wall of the outer cylinder 19 is fixedly connected to a round protrusion 20, wherein the hydraulic rod 1 5 and the hydraulic rod 2 15 are both waterproof.

[0043] A top cylinder block 22 is fixedly connected to the middle of the top of the rotating plate 21. A spiral driving groove 23 is opened on the outer wall of the top cylinder block 22. The driving groove 23 is slidably connected with the round protrusion 20. When the hydraulic rod 15 pushes the round block 16 to move vertically, the round protrusion 20 and the driving groove 23 slide down, so that the entire rotating plate 21 is rotated and connected at the connecting concave block 12. The top cylinder block 22 is coaxially arranged with the inner rod 17, and the inner rod 17 moves in the top cylinder block 22.

[0044] The implementation principle of the environmentally friendly urban sewage purification pretreatment device in the embodiment of the present application is:

[0045] First, close the water inlet. After the device is installed, release the sewage along the guide frame 1 into the cylinder block 2. First, the larger garbage will be blocked by the grille 3. As the blockage progresses, the water will continue to rise and pass over the grille 3, allowing excess water to enter the cylinder block 2. The water flows along the cylinder block 2 into the outer filter cylinder 4. The garbage that has been initially screened by the grille 3 will enter the inner filter cylinder 8.

[0046] The hydraulic rod 2 15 is synchronously started to reciprocate vertically, and the sliding of the round protrusion 20 and the driving groove 23 will drive the entire rotating plate 21 to rotate in the forward and reverse directions by relying on the bottom rotating block 26 and the connecting recessed block 12, wherein the plug plate 18 will synchronously slide vertically along the movable cavity 24, and the internal medium can be sprayed / absorbed outwardly through the connecting pipe 25, so that the garbage adhering to the inner side of the inner filter cartridge 8 can be cleaned by the rotating plate 21 that rotates forward and backward, and finally cleaned into the collection filter cartridge 11 that can be quickly disassembled and assembled along with the rotating plate 21.

[0047] When the sensor on the top of the collection filter cartridge 11 is excited or cleaned regularly, the sewage inlet is closed, and then the two hydraulic rods 15 are started to push the entire outer filter cartridge 4 upward, so that the grille 3 and the two collection filter cartridges 11 can be manually cleaned. After cleaning, they are returned to their original positions and put into use again.

[0048] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
