Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a river wastewater sediment filtration device. Background Technology

[0002] River sewage contains not only silt but also garbage such as bags and fallen leaves, so filtration equipment is needed to filter out the silt and garbage in the sewage.

[0003] However, the following drawbacks still exist. In existing river sewage treatment filtration equipment, sewage is usually discharged into the same tank for centralized treatment of silt and garbage. Since the treatment methods for garbage and silt in river sewage are different, centralized treatment means that subsequent sorting is required, which not only reduces the efficiency of sewage treatment but also increases the difficulty of subsequent treatment. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a river sewage and sediment filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A river sludge and sediment filtration device includes a water tank, a U-shaped frame, and two base plates. A drain outlet is provided on one side of the bottom of the water tank, and a drain pipe is fixedly connected to the drain outlet. A filter plate is installed at one end of the drain pipe. Fixed columns are fixedly connected to the upper surfaces of both base plates. An L-shaped frame is movably connected to the outer side of the fixed columns. A sliding groove is provided on the top of the L-shaped frame. Mounting plates are fixedly connected to both sides of the top of the U-shaped frame, and the mounting plates are slidably connected to the corresponding sliding grooves. Multiple second threaded holes are provided on the mounting plates. Multiple first threaded holes are provided on the top of the L-shaped frame. Lead screws are movably connected to the first threaded holes and their corresponding second threaded holes. An electric push rod is fixedly connected to the upper surface of the base plates. A connecting plate is fixedly connected to one side of the L-shaped frame, and the connecting plate is fixed to the extended end of the electric push rod. A connecting frame is fixedly connected to the bottom of the U-shaped frame. Filter cylinders are provided in both rings of the connecting frame. Two stirring components extending into the filter cylinders are provided at the bottom of the U-shaped frame.

[0007] As a further embodiment of this utility model, the stirring assembly includes a motor, which is fixed to the top outer wall of the U-shaped frame by bolts. A rotating shaft is movably connected to the top inner wall of the U-shaped frame, and multiple stirring rods are fixedly connected to the bottom end of the rotating shaft. One end of the motor output shaft is fixed to the rotating shaft at the corresponding position, and the stirring rods extend into the filter cylinder.

[0008] As a further improvement of this utility model, a water inlet is provided on one side of the filter cartridge.

[0009] As a further embodiment of this utility model, two guide rods are fixedly connected to the upper surface of the base plate, and the L-shaped frame slides along the guide rods.

[0010] As a further improvement of this utility model, the U-shaped frame can drive the filter cartridge to extend into the water tank.

[0011] As a further embodiment of this utility model, a limiting ring is fixedly connected to the outer circumferential wall of the filter cartridge, and the limiting ring rests above the connecting frame.

[0012] As a further embodiment of this utility model, a locking nut is movably connected to the bottom end of the lead screw through the outer side of the L-shaped frame, and the locking nut is in contact with the L-shaped frame.

[0013] As a further improvement of this utility model, the bottom of the base plate is fixed with two universal wheels equipped with brakes by screws.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the combined use of filter cartridges and water tanks, facilitates the separate filtration of silt and garbage in river sewage. Compared with unified centralized filtration, it saves operation steps, facilitates subsequent further treatment, and improves the effectiveness of the device.

[0016] 2. This utility model uses a detachable connection between the L-shaped frame and the U-shaped frame, which makes it easy for workers to adjust and fix the distance between the two L-shaped frames, thereby enabling the device to be used with water tanks of different lengths and improving the flexibility of the device.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-3 A river sewage silt filtration device includes a water tank 11, a U-shaped frame 5 and two base plates 9. A drain outlet is provided on one side of the bottom of the water tank 11. A drain pipe is connected and fixed inside the drain outlet. A detachable filter plate is installed at one end of the drain pipe. The filter plate can filter the silt in the water tank 11. The drain pipe can be connected to an external pipe to discharge the filtered water in the water tank 11, which is convenient for subsequent filtration treatment.

[0024] In this scheme, the upper surfaces of the two base plates 9 are fixed with fixing columns 20 by bolts. An L-shaped frame 7 is slidably connected to the outside of the fixing column 20. A sliding groove 17 is opened on the top of the L-shaped frame 7. Mounting plates are welded to both sides of the top of the U-shaped frame 5, and the mounting plates are slidably connected to the sliding groove 17 at the corresponding positions.

[0025] The mounting plate has multiple second threaded holes 3, and the top of the L-shaped frame 7 has multiple first threaded holes 2. The first threaded holes 2 and the corresponding second threaded holes 3 are internally threaded with screw rods 1. Rotate the screw rods 1 to move them out of the second threaded holes 3 and the first threaded holes 2. Then pull the L-shaped frame 7 horizontally to move the mounting plate along the slide 17 to the required position. Then reinsert the screw rods 1 into the corresponding first threaded holes 2 and second threaded holes 3 to fix them. At this time, the distance between the two L-shaped frames 7 is changed, so that the device can be used for water tanks 11 of different lengths.

[0026] The bottom end of the lead screw 1 is threaded through the outer side of the L-shaped frame 7 and a locking nut 14 is connected. The locking nut 14 is in contact with the L-shaped frame 7. The locking nut 14 can further restrict the position of the lead screw 1 and prevent the lead screw 1 from easily rotating in the opposite direction and affecting the connection effect.

[0027] An electric push rod 19 is fixed to the upper surface of the base plate 9 by bolts. A connecting plate 18 is fixed to one side of the L-shaped frame 7 by bolts, and the connecting plate 18 is fixed to the extended end of the electric push rod 19. Two guide rods 8 are fixed to the upper surface of the base plate 9 by bolts, and the L-shaped frame 7 slides along the guide rods 8. The guide rods 8 can guide the L-shaped frame 7 so that it can move up and down stably.

[0028] In this utility model, it should be noted that the bottom of the U-shaped frame 5 is fixed with a connecting frame 15 by bolts. The two rings of the connecting frame 15 are each provided with a filter cylinder 16. The bottom of the U-shaped frame 5 is provided with two stirring components that extend into the filter cylinder 16. The stirring components include a motor 6. The motor 6 is fixed to the top outer wall of the U-shaped frame 5 by bolts. The top inner wall of the U-shaped frame 5 is rotatably connected with a rotating shaft 4. One end of the output shaft of the motor 6 is fixed to the rotating shaft 4 at the corresponding position.

[0029] Multiple stirring rods 10 are fixed to the bottom of the rotating shaft 4 by couplings and bolts. The stirring rods 10 extend into the filter cylinder 16. The rotation of the motor 6 causes the rotating shaft 4 to drive the stirring rods 10 to rotate, thereby agitating the sewage impurities in the filter cylinder 16 and preventing sludge impurities from easily clogging the filter holes on the filter cylinder 16.

[0030] The U-shaped frame 5 can drive the filter cartridge 16 into the water tank 11. The outer circumference of the filter cartridge 16 is fixed with a limiting ring 13 by bolts. The diameter of the limiting ring 13 is not less than the diameter of the circular part of the connecting frame 15. The limiting ring 13 rests on the connecting frame 15. The limiting ring 13 can restrict the placement position of the filter cartridge 16 in the circular part of the connecting frame 15, making its installation more stable.

[0031] Two casters 12 with brakes are fixed to the bottom of the base plate 9 by screws. The electric push rod 19 extends to move the L-shaped frame 7 upward along the fixed column 20, thereby causing the U-shaped frame 5 to drive the two filter cartridges 16 on the connecting frame 15 to move upward, so that the filter cartridges 16 are removed from the water tank 11. Then the base plate 9 is pushed, so that the base plate 9, L-shaped frame 7 and U-shaped frame 5 and their connected components move as a whole through the casters 12, which makes it easier for the staff to separate the garbage in the filter cartridges 16 from the water tank 11.

[0032] Working principle: When it is necessary to filter river sewage, the river sewage is connected to the inlet of the two filter cylinders 16 through two external pipes, allowing the sewage to enter the filter cylinders 16 through the pipes. The sewage is filtered through the filter holes at the bottom of the filter cylinders 16, and the garbage is filtered into the filter cylinders 16. At the same time, the motor 6 is started. The rotation of the motor 6 causes the rotating shaft 4 to drive the stirring rod 10 to rotate, thereby agitating the sewage and impurities in the filter cylinders 16, preventing sludge and impurities from clogging the filter holes on the filter cylinders 16, and allowing the sludge to be discharged better.

[0033] At this point, the wastewater that has undergone one filtration enters the water tank 11. Then, the wastewater containing mud and sand in the water tank 11 is filtered through the filter plate in the drain pipe to remove the mud and sand, and the wastewater after filtration is discharged. The discharged wastewater is connected to the external water supply equipment for convenient subsequent treatment.

[0034] When it is necessary to process the impurities collected in the filter cartridge 16, the electric push rod 19 is activated. The electric push rod 19 extends, causing the L-shaped frame 7 to move upward along the fixed column 20. This causes the U-shaped frame 5 to move the two filter cartridges 16 on the connecting frame 15 upward, so that the filter cartridges 16 are removed from the water tank 11. Then, the base plate 9 is pushed, so that the base plate 9, the L-shaped frame 7, the U-shaped frame 5 and their connected components move as a whole through the casters 12, which makes it easier for the staff to separate the garbage in the filter cartridge 16 from the water tank 11.

[0035] When it is necessary to adjust the distance between the two L-shaped frames 7, the locking nut 14 is separated from the L-shaped frame 7, the screw 1 is rotated to move it out of the second threaded hole 3, and then the L-shaped frame 7 is pulled horizontally to move the mounting plate along the slide groove 17 to the required position. Then the screw 1 is reinserted into the corresponding first threaded hole 2 and second threaded hole 3 to fix it. At this time, the distance between the two L-shaped frames 7 is changed, so that the device can be used for water tanks 11 of different lengths.

[0036] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
