Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a multi-layer barrier filtration device for a river. Background Art

[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as initial rain runoff into drainage pipes. With the rapid development of cities, more and more wastewater is generated in people's lives. Many people do not pay attention to environmental protection and discharge sewage into rivers at will, making it difficult to control.

[0003] The sewage in the river will bring up some of the silt at the bottom of the riverbed during the suction and diversion process, resulting in blockage in the filter device when filtering the river sewage, affecting the filtration and separation efficiency of the equipment. In addition, the sewage will also be mixed with various floating garbage, which will also cause blockage during the separation process. Most wastewater treatment devices generally only filter through a single grid when filtering wastewater, which not only has poor filtering effect, but also is inconvenient to clean. Excessive impurities in the wastewater can easily cause the grid to become blocked, which has a certain impact on wastewater filtration. For this reason, we propose a multi-layer barrier filter device for rivers to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: a multi-layer barrier filtration device for a river channel, comprising a separation box 1, a sludge interception frame 2 and a separation screen frame 4 installed inside the separation box 1, a sealing plate 11 is installed on the top of the separation box 1, a circular groove is opened on the side wall of the separation box 1, and a water inlet pipe 12 is installed inside the circular groove, and the water inlet pipe 12 is higher than the sludge interception frame 2 and the separation screen frame 4, a pair of clamping frames are installed inside the separation box 1, and the sludge interception frame 2 and the separation screen frame 4 are both clamped inside the clamping frames;

[0032] At least one group of suspension frames 3 is installed on the sludge retention frame 2. The suspension frames 3 are floated on the top of the separation box 1. The suspension frames 3 can collect and clean floating dirt, etc. When the sewage needs to be cleaned, the sewage can be transferred to the inside of the separation box 1 under the action of an external water pump. During the transmission process, the sewage passes through the sludge retention frame 2 and the separation screen frame 4, and the sewage can be separated and screened layer by layer. Compared with the traditional single-layer grille, it can reduce the accidental blockage.

[0033] like Figure 4 As shown, sludge accumulation can easily cause blockage inside the filtration equipment. The sludge retention frame 2 is rectangular and has a plurality of fixed partitions 21 installed inside. The fixed partitions 21 are arranged in a uniform array inside the sludge retention frame 2. A plurality of movable plug plates 22 are inserted on the fixed partitions 21. The movable plug plates 22 and the fixed partitions 21 are vertically staggered. Elastic end blocks are provided at both ends of the movable plug plates 22, and the elastic end blocks are clamped inside the sludge retention frame 2 to control the range of movement of the movable plug plates 22. A grid screen plate is installed between the movable plug plates 22 and the fixed partitions 21, and the grid screen plate is elastic. As the movable plug plates 22 move, the grid screen plate can be pulled to move, which can reduce the stone debris in the sludge from being stuck inside the grid screen plate. At the same time, it can stir the water flow to prevent multi-level sludge and quickly screen and divert the incoming sewage.

[0034] like Figure 5 As shown, the sludge is also easily mixed with various debris and impurities. A reset plate 23 is installed on the top of the movable plug plate 22. The reset plate 23 is elastic and has a plurality of separation holes on its surface. A transmission frame 24 is installed on the top of the reset plate 23. The transmission frame 24 is clamped on the top of the movable plug plate 22. Connecting shafts 25 are installed at both ends of the transmission frame 24. The connecting shafts 25 are elastic. As the connecting shafts 25 move under the action of the suspension frame 3, the transmission frame 24 can move. The reset plate 23 can squeeze and mix the sludge clamped therebetween, and can quickly mix the sludge into the water flow, separate the residual debris and aquatic plant roots inside, and reduce the accumulation and aggregation thereof leading to local blockage.

[0035] like Figure 3 As shown, in order to reduce the situation where floating objects remain in the sewage, limit plates 31 are installed at both ends of the suspension frame 3, the bottom of the limit plate 31 is hook-shaped, and the bottom of the limit plate 31 is clamped on the connecting shaft 25;

[0036] A positioning ring 33 is installed at the top of the suspension frame 3. The positioning ring 33 is elastic and has a plurality of toggle shafts 34 on the side wall. The toggle shafts 34 are arc-shaped. A plurality of through grooves are provided on the suspension frame 3. Part of the toggle shafts 34 are movably arranged inside the through grooves. A plurality of semicircular grooves are provided on the inner wall of the toggle shaft 34, and a plurality of metal hooks are installed inside the semicircular grooves. With the help of the toggle shaft 34, floating garbage floating on the surface of the sewage can be collected, and with the help of the metal hooks, the surface of the floating objects can be scratched. When the sewage is screened, the residual sewage in the floating garbage can be reduced, which is convenient for subsequent collection and prevents it from falling on the top of the sludge retention frame 2 along the gap of the toggle shaft 34 under the action of gravity.

[0037] like Figure 3 As shown, in order to reduce the floating garbage and the like from flowing along the water flow to the top of the sludge interception frame 2, a plurality of barrier rings 35 are installed on the outer wall of the toggle shaft 34. The barrier rings 35 are arranged in a uniform array on the outer side of the toggle shaft 34. A plurality of straight grooves are opened on the barrier ring 35, and a plurality of positioning shafts are clamped inside the straight grooves to limit the winding of the floating plastic bag garbage and the like, thereby enhancing the limiting and collecting function of the device.

[0038] An expansion ball 32 is installed inside the suspension frame 3, and the bottom of the expansion ball 32 is against the bottom end of the toggle shaft 34. When the water flows, the expansion ball 32 can be deformed under the action of buoyancy, thereby driving the toggle shaft 34 to swing, and can push and wind the floating garbage, etc., so that it is stuck on more than one positioning shaft to assist in limiting.

[0039] like Figure 6 As shown, the sewage filtering equipment is prone to blockage during long-term processing, resulting in reduced separation efficiency. A plurality of support frames 42 are installed inside the separation screen frame 4, and the support frames 42 are arranged in a uniform array inside the separation screen frame 4. A hollow sieve plate 41 is clamped inside the support frame 42, and a limiting groove 43 is provided between the side wall of the hollow sieve plate 41 and the separation screen frame 4, and a positioning plug plate 44 is clamped inside the limiting groove 43. A gap is provided between the top of the support frame 42 and the hollow sieve plate 41, and a plurality of elastic barbs are installed at the bottom of the inner wall of the support frame 42 for collecting debris and impurities to reduce blockage. When the sewage is transmitted to the top of the separation screen frame 4, as the top sludge retention frame 2 stirs the water flow, the debris in the sewage can be transmitted between the elastic barbs at the bottom of the support frame 42, which can reduce the dirt and the like remaining on the surface of the hollow sieve plate 41 to cause blockage, thereby ensuring the screening efficiency of the equipment.

[0040] like Figure 7 As shown, in order to further reduce impurities in sewage, a limiting tube 45 is installed at the top of the positioning plug plate 44, and a plurality of water inlet grooves are opened on the side wall of the limiting tube 45. A movable plug rod 46 is inserted inside the limiting tube 45, and a clamping frame 461 is installed at the top of the movable plug rod 46. The clamping frame 461 is clamped between the bottoms of the movable plug plates 22;

[0041] A plurality of fixing rings 471 are installed on the side wall of the limiting tube 45, an adsorption ring 47 is installed on the outer wall of the fixing ring 471, and a plurality of clamping pieces are installed on the inner wall of the adsorption ring 47. The movable plug plate 22 can drive the movable plug rod 46 to reciprocate, so that the water flows into the water inlet trough, and when the movable plug rod 46 is reset, the sewage inside the limiting tube 45 can be pushed out to flow along the adsorption ring 47, and the excess dirt inside can be stuck between the limiting pieces, which can play a role of auxiliary adsorption and can collect and process impurities suspended in the water.

[0042] like Figure 2 As shown, a pair of observation ports 14 are installed at the top of the sealing plate 11, and a fixed ladder 13 is installed on the side wall of one side of the observation port 14 to facilitate subsequent observation by the staff.

[0043] Working principle: First, when it is necessary to clean the sewage, the sewage can be transferred to the separation box 1 under the action of the external water pump. During the transmission process, the sewage passes through the sludge interception frame 2 and the separation screen frame 4, and the sewage can be separated and screened layer by layer. Compared with the traditional single-layer grille, it can reduce the accidental blockage. In addition, as the sewage is diverted, the sludge can be stuck between the fixed partition plate 21 and the movable plug plate 22. As the external sewage flows and is transmitted, the suspension frame 3 can swing under the action of the water flow, and the connecting shaft 25 can be pulled to move by the limit plate 31, so that the movable plug plate 22 can reciprocate during the transmission process, and the sludge at the bottom can be stirred to follow the water flow, so as to avoid the accumulation of the sludge at the top of the sludge interception frame 2 during the transmission process, so that the sewage can be quickly separated and discharged;

[0044] Then, during the activity of the suspension rack 3, debris and impurities floating on the sewage surface can be gathered between the toggle shafts 34, and the plastic garbage can be wound on its surface with the help of the positioning shaft. When there is water in the plastic garbage that is inconvenient to discharge, the plastic garbage can be brought into contact with the metal hook inside the toggle shaft 34, so that the plastic garbage can be cut and the sewage inside can be quickly discharged, so that the garbage debris accumulated on the top of the suspension rack 3 can be cleaned and maintained uniformly from the observation port 14 later.

[0045] Finally, when the sewage is transmitted to the top of the separation screen frame 4, as the top sludge retention frame 2 stirs the water flow, the debris in the sewage can be transmitted to the elastic barbs at the bottom of the support frame 42, which can reduce the dirt and the like remaining on the surface of the hollow screen plate 41 and causing blockage. The movable plug plate 22 can drive the movable plug rod 46 to reciprocate, so that the water flows into the water inlet trough. When the movable plug rod 46 is reset, the sewage inside the limiting tube 45 can be pushed out to flow along the adsorption ring 47, and the excess dirt inside can be stuck between the limiting pieces, which can play a role in auxiliary adsorption and facilitate subsequent maintenance and cleaning.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
