Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated steel rolling water filtration and treatment device. Background Technology

[0002] With the acceleration of industrialization and population growth, wastewater discharge is constantly increasing, with industrial wastewater accounting for a considerable proportion. Industrial wastewater typically contains various toxic and harmful substances, such as heavy metals, organic matter, and grease. These substances not only pollute water bodies but also pose serious threats to aquatic life and human health. Therefore, it is of great significance to carry out effective treatment of industrial wastewater to reduce its negative impact on the environment and human health.

[0003] Chinese utility model patent with announcement number CN218709730U and application number 202222581010.1 discloses an industrial wastewater treatment and recycling discharge device, including a sewage tank, a sedimentation tank, and a cleaning tank. A base tank is fixedly connected to the bottom of each of the sewage tank, sedimentation tank, and cleaning tank. Drainage pipes are fixedly connected to the surfaces of each of the three tanks, and a sewage discharge pipe is fixedly connected to the surface of the base tank. A cap is fitted onto the top of each of the three tanks. An inlet pipe is fixedly connected to the end face of one cap of the sewage tank, a flushing pipe is fixedly connected to the end face of one cap of the sedimentation tank, and a return pump is fixedly connected to the end face of one cap of the cleaning tank. A return pipe is fixedly connected to the output end of the return pump. Wastewater enters the sewage tank for primary filtration, then enters the sedimentation tank for secondary filtration, and finally passes through the cleaning tank for final filtration. The wastewater is then circulated back to the sewage tank and sedimentation tank through the return pipe for rinsing and cleaning.

[0004] This patented technology filters and degrades industrial wastewater multiple times, and the wastewater tank and sedimentation tank can be cleaned through the cleaning tank, realizing the recycling of wastewater. However, there are still some problems in the use of this technology: three tanks are required to complete the entire cleaning process, and the device occupies too much space. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated steel rolling slurry filtration and treatment device to solve the problem that three tanks are needed to complete the entire cleaning process and the device occupies too much space.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: an integrated steel rolling slurry filtration and treatment device, comprising a tank body, a main inlet pipe running through the tank body, a main inlet valve installed on the main inlet pipe, an upper inlet pipe and a lower inlet pipe connected to the main inlet pipe, a water storage filter element one and a water storage filter element two installed inside the tank body, the end of the upper inlet pipe away from the main inlet pipe connected to the water storage filter element one, and the end of the lower inlet pipe away from the main inlet pipe connected to the water storage filter element two, a drain pipe running through the tank body, a drain valve installed on the drain pipe, an upper outlet pipe and a lower outlet pipe connected to the drain pipe, the upper outlet pipe being away from the drain pipe... One end of the pipe is connected to the first water storage filter element, and the end of the lower outlet pipe away from the sewage pipe is connected to the second water storage filter element. The tank is equipped with a sterilization and purification layer, which is located below the first and second water storage filters. The tank is equipped with a lower shell, and a main outlet pipe is connected to the lower shell. A main outlet valve is installed on the main outlet pipe. The end of the main outlet pipe away from the lower shell is connected to a main return water pipe. An upper flushing pipe and a lower flushing pipe run through the tank. Both the upper flushing pipe and the lower flushing pipe are connected to a backwash main pipe. The backwash main pipe is connected to the main return water pipe. A booster pump is installed on the backwash main pipe, and a backwash water valve is installed on the backwash main pipe.

[0007] The principle and beneficial effects of this utility model are as follows: Wastewater flows into the main inlet pipe, and then enters the first and second water storage filter elements through the upper and lower inlet pipes respectively for the first stage of sedimentation and filtration. The settled sludge is discharged through the sludge discharge pipe. The sludge-free water flows through the upper and lower outlet pipes to the sewage discharge pipe, and then through the screen pipe into the sterilization and purification layer for the second stage of filtration. The water after the second filtration flows from the main outlet pipe to the main return pipe, and a portion of it enters the backwash main pipe through the booster pump. It then flows back into the tank through the upper and lower flushing pipes to flush away the sludge and scale adhering to the inside. The flushing water undergoes two more filtrations and is finally discharged through the main outlet pipe. This tank flushing device, which integrates sedimentation, filtration, and circulation, enhances wastewater purification through two internal filtration processes, reduces environmental pollution after wastewater discharge, reduces the footprint, and the circulating flushing reduces water waste and increases work efficiency.

[0008] Option 2, an optimized version of the basic option, includes a water storage filter element one comprising an inclined tube packing layer with a sleeve running through it. A water storage tank is connected inside the sleeve, and a water collection trough is located on the sleeve. A sludge collection hopper is located inside the tank, below the inclined tube packing layer. A sludge discharge pipe is connected to one side of the sludge collection hopper, and a sludge discharge valve is installed on the discharge pipe. The end of the discharge pipe furthest from the sludge collection hopper passes through the tank body. Water storage filter element one has the same structure as water storage filter element two, but it is located above it. Two inlet pipes connect to the sludge collection hopper and the water storage tank, respectively. Wastewater flows from the water storage tank to the sludge collection hopper. As the water rises, it first passes through the inclined tube packing layer, where sludge in the wastewater is simply adhered, before flowing into the water collection trough. Using two sets of water storage filters allows for the simultaneous filtration of large quantities of water in batches, increasing work efficiency.

[0009] Option 3, a preferred option of Option 2, comprises an inclined tube packing layer consisting of two partitions with several through holes, and several ceramic inclined tubes positioned between the partitions. Wastewater flows into the inclined tube packing layer through the through holes in the partitions, where the sludge is separated from the wastewater by the ceramic inclined tubes. The ceramic material of the inclined tubes is chosen for its strong adsorption capacity, which increases the adhesion of sludge and enhances the separation effect between water and sludge.

[0010] Option 4, an optimized version of the basic option, includes a sterilization and purification layer comprising a support plate connected to the inner wall of the tank. Several porous fiber balls are placed on the support plate, and several filter caps are threaded through it. A support rod is located at the bottom of the support plate and connected to the lower shell. Using porous fiber balls for secondary filtration and purification of wastewater allows for high-precision filtration, effectively removing bacteria, viruses, and large organic molecules. The filtration speed is also fast; compared to filters using quartz sand or anthracite, porous fiber balls can maintain a longer filtration cycle. The filter caps are made of stainless steel, which is corrosion-resistant, not easily damaged, extends service life, and reduces operating costs.

[0011] Option 5, a preferred option to Option 2, involves a drain pipe connected to a four-way pipe at one end inside the tank. Three screen pipes are connected to the other channels of the four-way pipe, and all three screen pipes are connected to the inner wall of the tank. The screen pipes can filter and isolate unsettled particulate impurities in the wastewater, preventing clogging and reducing maintenance frequency and costs during operation.

[0012] Option six, an optimal choice from the basic option, features a chemical inlet at one end of the main water inlet pipe located outside the tank. Introducing a catalyst to accelerate the separation of precipitates through this inlet enhances the separation effect.

[0013] Option 7, an optimal choice from the basic option, features a float-type vent valve at the top of the tank. During operation, this valve allows air generated inside the tank to escape, ensuring smooth water flow and preventing air blockages and pressure instability.

[0014] Option 8, a preferred option of the basic design, features two manholes on one side of the tank and a third manhole at the top, with manhole 1 located above manhole 2. Having manholes in three directions allows for multi-faceted observation of the wastewater filtration and structural condition within the tank. Attached Figure Description

[0022] The specific implementation method of this embodiment is as follows:

[0023] 1. During wastewater filtration and purification, the initial wastewater is diverted from the main inlet pipe 2 to the upper inlet pipe 3 and the lower inlet pipe 4. Wastewater entering the upper inlet pipe 3 first flows into the storage tank 17, where it accumulates. When the water reaches the opening of the storage tank 17, it flows downwards along the gap between the storage tank 17 and the sleeve 16 to the sludge collection hopper 19. As wastewater is input, the water level in the sludge collection hopper 19 rises, flowing upwards through the through-hole of the baffle 15. As it passes through the ceramic inclined tube 21, sludge is adsorbed. The adsorbed sludge settles into the sludge collection hopper 19. The wastewater that has adsorbed sludge continues to rise, flowing into the collection tank 18, and then from the upper outlet pipe 6 to the sewage discharge pipe 5. The wastewater in the lower inlet pipe 4 and... The sewage from the upper inlet pipe 3 undergoes the same process, and then flows from the lower outlet pipe 7 into the drain pipe 5. At this time, the drain pipe 5 and the sludge discharge pipe 22 are closed. The sewage from the drain pipe 5 is diverted through the four-way pipe 20 into several screen pipes 8. After passing through the screen pipes 8, it flows downward into the sterilization and purification layer. Several porous fiber balls 28 perform final sterilization and purification on the sewage. The purified water flows downward into the lower shell 9 through several filter caps 29, and finally is discharged into the water storage tank from the main outlet pipe 10. When all the water is discharged, the main inlet pipe 2 and the main outlet pipe 10 are closed, and the drain pipe 5 and the sludge discharge pipe 22 are opened. The sludge in the tank 1 is discharged from the sludge discharge pipe 22, and the sewage remaining in the tank 1 is discharged from the drain pipe 5.

[0024] 2. During backwashing, close the main inlet pipe 2 and the main outlet pipe 10. Part of the water flows through the pressure in the main return pipe 11 to the next tank. There are 16 identical tanks in series. Part of the water is drawn back from the backwash main pipe 14 by the booster pump 32. The drawn-back water is sprayed into the tank 1 from the upper flushing pipe 12 and the lower flushing pipe 13 respectively, cleaning the scale attached to the inner wall, inclined plate filter layer, sterilization and purification layer and other internal components of the tank 1 in sequence. The wastewater after cleaning is discharged from the drain pipe 5 and the sludge is discharged from the sludge discharge pipe 22. After the wastewater is discharged, the next round of wastewater filtration process can begin.
