Description

Technical Field

[0001] This utility model relates to the technical field of filtration devices, specifically to a mobile high-strength multi-layer filtration device for cooling tower water collection tanks. Background Technology

[0002] Currently, in industrial circulating cooling water systems, to better save costs and optimize water use, used water needs to be cooled down by a cooling tower before being recycled to reduce water loss and achieve optimal water utilization. In existing designs, high-temperature water is typically cooled by a spray packing material and then flows into a lower collection tank through a drain at the bottom of the collection trough, where it is pumped back to the production equipment for reuse. A filter screen is installed at the drain at the bottom of the collection trough to prevent debris from entering, but this screen is easily clogged by broken packing material, flocculants, sludge, and other debris. Clogging causes water to overflow from the collection tank and prevents timely return, thus affecting the overall water circulation system and causing production stoppages that directly impact economic losses. Therefore, the existing technology suffers from the technical problem of unstable circulating water return. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a mobile high-strength multi-layer filtration device for cooling tower water collection tank, which includes a base plate, an inner layer filtration structure, an outer layer filtration structure and a frame structure. This mobile high-strength multi-layer filtration device for cooling tower water collection tank has the advantage of stable return water.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A mobile high-strength multi-layer filtration device for cooling tower water collection tanks includes a base plate, an inner layer filtration structure, an outer layer filtration structure, and a frame structure.

The two ends of the baffle plate are fixedly connected to the first inner filter plate and the weir plate, respectively. The frame structure is connected to both the weir plate and the first inner filter plate.

[0006] This design prevents debris from clogging the inner and outer filter layers, ensuring smooth water return. It effectively reduces water overflow caused by blockages, extending equipment lifespan, minimizing economic losses from production stoppages, and achieving stable water return.

[0007] Preferably, there are two first inner filter plates, which are located at both ends of the second inner filter plate and on the same side of the second inner filter plate.

[0008] This configuration balances the forces on the second inner filter plate, improving the stability and reliability of the inner filtration structure.

[0010] This setting reduces the water flow rate, preventing impurities denser than water from being washed to the serrated edges, thus promoting sedimentation and improving filtration efficiency.

[0011] Preferably, the first inner filter plate is provided with a plurality of third filter holes, the diameter of the third filter holes being larger than the diameter of the second filter holes, and the third filter holes being located above the first filter holes.

The first transverse rod and the second transverse rod are both fixedly connected to the longitudinal rod. Both ends of the first transverse rod and the second transverse rod are fixedly connected to the cofferdam plate. Both ends of the longitudinal rod are fixedly connected to the cofferdam plate and the baffle plate, respectively. The first transverse rod passes through the first inner filter plate and is fixedly connected to the first inner filter plate. The second transverse rod is fixedly connected to the second inner filter plate.

[0014] This setup enables the cofferdam plate, the first inner filter plate, and the second inner filter plate to support each other through a frame structure.

[0015] Preferably, the first transverse rod, the second transverse rod, and the second inner filter plate are parallel, and the second transverse rod is attached to the side of the second inner filter plate away from the water inlet tank.

The first partition is parallel to the first inner layer filter plate, and the second partition is parallel to the second inner layer filter plate. The two first partitions are fixedly connected to both ends of the second partition.

[0022] This design effectively reduces the amount of debris floating on the liquid surface that is discharged from the filter device, thereby improving the filtration effect.

[0023] Preferably, the base plate is fixedly connected to a support plate, and the support plate is fixedly connected to the first inner filter plate.

[0025] Compared with the prior art, this utility model has achieved beneficial technical effects:

[0026] 1. In this application, water is filtered through an inner filtration structure and an outer filtration structure.

However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0036] refer to Figure 1 A mobile high-strength multi-layer filtration device for cooling tower water collection tank includes a base plate 10, an inner layer filtration structure 20, a middle layer filtration structure 50, an outer layer filtration structure 30, and a frame structure 40. The inner layer filtration structure 20 and the outer layer filtration structure 30 are both fixed on the base plate 10.

[0037] refer to Figure 1 and Figure 2The inner filtration structure 20 includes a first inner filter plate 21 and a second inner filter plate 22. Both the first inner filter plate 21 and the second inner filter plate 22 are fixedly connected to the base plate 10. The first inner filter plate 21 has multiple first filter holes 23. The first inner filter plate 21 and the second inner filter plate 22 surround each other to form an inlet groove 11. The first inner filter plate 21 and the second inner filter plate 22 are perpendicular to each other and are fixedly connected. A support plate 13 is fixedly connected to the base plate 10, and the support plate 13 is fixedly connected to the first inner filter plate 21. There are two first inner filter plates 21, which are located at both ends of the second inner filter plate 22 and on the same side of the second inner filter plate 22. A water inlet 12 is provided on the side of the water inlet tank 11 away from the second inner filter plate 22. The second inner filter plate 22 has multiple second filter holes 24, and a closed area 26 is provided at the lower end of the second inner filter plate 22. The multiple second filter holes 24 are located above the closed area 26. The first inner filter plate 21 has multiple third filter holes 25. The diameter of the third filter holes 25 is larger than the diameter of the second filter holes 24, and the third filter holes 25 are located above the first filter holes 23.

[0038] The outer filtration structure 30 includes a weir plate 31 and a baffle plate 32. The weir plate 31 is located on the side of the first inner filter plate 21 and the second inner filter plate 22 away from the inlet tank 11. The upper end of the weir plate 31 is provided with serrations 33. The two ends of the baffle plate 32 are fixedly connected to the first inner filter plate 21 and the weir plate 31, respectively. The baffle plate 32 is located at the end of the first inner filter plate 21 away from the second inner filter plate 22. The baffle plate 32 can block the water filtered by the inner filtration structure 20 and direct the water flow to the outer filtration structure 30, ensuring that the water after passing through the inner filtration structure 20 can pass through the outer filtration structure 30. The frame structure 40 is connected to the weir plate 31 and the first inner filter plate 21, respectively.

[0039] refer to Figure 1 and Figure 3The frame structure 40 includes a first transverse rod 41, a second transverse rod 42, and a longitudinal rod 43. Both the first transverse rod 41 and the second transverse rod 42 are fixedly connected to the longitudinal rod 43. Both ends of the first transverse rod 41 and the second transverse rod 42 are fixedly connected to the cofferdam plate 31. Both ends of the longitudinal rod 43 are fixedly connected to the cofferdam plate 31 and the baffle plate 32, respectively. The first transverse rod 41 passes through the first inner filter plate 21 and is fixedly connected to the first inner filter plate 21. The second transverse rod 42 is fixedly connected to the second inner filter plate 22. The frame structure 40 is located on the side of the cofferdam plate 31 closest to the inlet trough 11. The cofferdam plate 31 has two right-angle bends surrounding the frame structure 40, allowing both ends of the first transverse rod 41 and the second transverse rod 42 to be fixedly connected to the side of the cofferdam plate 31 closest to the drainage trough, respectively. The first transverse rod 41, the second transverse rod 42, and the second inner filter plate 22 are parallel, with the second transverse rod 42 fitting against the side of the second inner filter plate 22 away from the inlet trough 11.

Two longitudinal rods 43 are provided, each corresponding to one of the two first inner filter plates 21. This ensures that the two longitudinal rods 43 can support the two first inner filter plates 21 respectively, guaranteeing the stability of both first inner filter plates 21.

[0040] refer to Figure 1 and Figure 4 The middle layer filter structure 50 is located between the inner layer filter structure 20 and the outer layer filter structure 30. A water passage groove 53 is provided between the middle layer filter structure 50 and the bottom plate 10. The serrations 33 are located above the water passage groove 53. The middle layer filter structure 50 includes a first partition 51 and a second partition 52. Two first partitions 51 are provided. The first partitions 51 are parallel to the first inner layer filter plate 21, and the second partitions 52 are parallel to the second inner layer filter plate 22. The two first partitions 51 are fixedly connected to both ends of the second partition 52. A first transverse rod 41 and a second transverse rod 42 pass through the first partitions 51 and are fixedly connected to the first partitions 51. A longitudinal rod 43 passes through the second partitions 52 and is fixedly connected to the second partitions 52.

[0041] This embodiment has the following advantages:

[0042] The circulating water, cooled by the water-spraying packing, enters the inlet tank 11 through inlet 12. The water in the inlet tank 11 flows through the first filter holes 23 towards the weir plate 31. Larger impurities, unable to pass through the first filter holes 23, are blocked by the first inner filter plate 21 within the inlet tank 11, thus achieving water filtration. After flowing towards the weir plate 31, the water level is at the serrations 33, allowing water to be discharged through the upper end of the weir plate 31, while impurities denser than water settle downwards, further filtration. Because the weir plate 31 surrounds the outer side of the inner filter structure 20, and its length is greater than that of the first and second inner filter plates 21 and 22, the increased interception area when water flows from the first filter holes 23 to the weir plate 31 reduces the water velocity, facilitating the downward settling of denser impurities. This promotes the sedimentation of impurities denser than water between the weir plate 31 and the inner filter structure 20. The sawtooth 33 has grooves whose width gradually decreases from top to bottom. When water and impurities floating on the water surface pass through the grooves, the water can pass through the grooves, while impurities that are wider than the grooves are blocked by the sawtooth 33 and cannot pass through the grooves, thereby achieving a further filtration function and achieving the advantage of better filtration effect.

[0043] In this application, water is filtered through an inner filter structure 20 and an outer filter structure 30. The filtered impurities are blocked on the inner filter structure 20 and the outer filter structure 30, respectively. This allows the impurities to be blocked on the inner filter structure 20 and the outer filter structure 30, thus dispersing the impurities and preventing them from clogging the inner filter structure 20 and the outer filter structure 30. This ensures smooth return of circulating water, effectively reduces the phenomenon of water overflow and failure to return water in time due to blockage, extends the service life of the equipment, reduces economic losses caused by production stoppage, and achieves the advantage of stable water return.

[0044] When debris accumulates on the inlet tank 11 and the weir plate 31, it can be removed directly above the bottom plate 10. This can clean the debris filtered out of the filter device while the water is returning, thus ensuring the stability of the return water of the circulating cooling water system.

[0045] The base plate 10 supports the cofferdam plate 31 and the first inner filter plate 21 from the bottom, and the frame structure 40 connects the cofferdam plate 31 and the first inner filter plate 21, so that the cofferdam plate 31 and the first inner filter plate 21 can support each other through the frame structure 40, thereby improving the structural stability and strength of the cofferdam plate 31 and the second inner filter plate 22.

[0046] The water is filtered simultaneously by two first inner filter plates 21, which improves the filtration efficiency. When the flowing water impacts the first inner filter plates 21, the two first inner filter plates 21 are located at opposite ends of the second inner filter plate 22, which balances the forces on the second inner filter plate 22, improves the stability and reliability of the inner filtration structure 20, and increases the structural strength.

[0047] When water flows into the inlet tank 11 through the inlet 12, the water flows towards the second inner filter plate 22. The closed area 26 blocks the flow of water, causing the flow direction to turn to the first inner filter plate 21. This reduces the water flow rate and prevents impurities with a density greater than water from being washed to the serrations 33. This promotes the downward sedimentation of impurities and improves the filtration effect.

[0048] When the water flow is too large and the liquid level in the inlet tank 11 rises to the third filter hole 25, the drainage speed can be increased through the third filter hole 25 with a larger aperture, so as to drain the water in time and prevent the circulating water level from overflowing due to excessive height.

[0049] The first transverse rod 41 is fixedly connected to the first inner filter plate 21 and the cofferdam plate 31, allowing the first inner filter plate 21 and the cofferdam plate 31 to transmit supporting forces through the first transverse rod 41. The second transverse rod 42 is fixedly connected to the second inner filter plate 22 and the cofferdam plate 31, allowing the second inner filter plate 22 and the cofferdam plate 31 to transmit supporting forces through the second transverse rod 42, realizing the function of mutual support between the cofferdam plate 31, the first inner filter plate 21 and the second inner filter plate 22 through the frame structure 40. The longitudinal rod 43 is fixed to the first transverse rod 41 and the second transverse rod 42, allowing the longitudinal rod 43, the first transverse rod 41 and the second transverse rod 42 to support each other, effectively improving the structural stability and strength of the filtration device.

[0050] The second transverse rod 42 is attached to the second inner filter plate 22, so that the second transverse rod 42 can stably support the second inner filter plate 22, preventing the second inner filter plate 22 from being deformed and damaged by the water flow in the water inlet tank 11, thus improving reliability.

[0051] The longitudinal rod 43 is attached to the first inner filter plate 21, so that the longitudinal rod 43 can stably support the first inner filter plate 21, preventing the first inner filter plate 21 from being deformed and damaged by the water flow in the water inlet tank 11, thus improving reliability.

[0052] Because the serrations 33 are located above the water channel 53, the water channel 53 is always below the liquid surface. When debris that can float on the liquid surface passes through the inner filter structure 20, most of the debris floating on the liquid surface is blocked by the first baffle 51 and the second baffle 52. Water then flows through the water channel 53 below the first baffle 51 and the second baffle 52 to the serrations 33, effectively reducing the amount of debris floating on the liquid surface discharged from the filter device and improving the filtration effect.

[0053] Since the first inner filter plate 21 has multiple first filter holes 23 and third filter holes 25, the support plate 13 further provides support to the first inner filter plate 21, thereby further ensuring the structural reliability of the first inner filter plate 21.

[0054] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
