Description

Technical Field

[0001] The present application relates to the field of water treatment technology, and in particular to a detachable and liftable filtering device. Background Art

[0002] Daily urban life generates a wide variety of waste, with food waste being a significant component. Food wastewater refers to the high-concentration organic wastewater containing edible waste oil, suspended solids, and other substances after solid-liquid separation. Ultrafiltration of food wastewater effectively removes pollutants such as suspended solids, organic matter, bacteria, and viruses, ensuring that the treated water meets national emission standards and can be used for urban greening, road cleaning, and landscaping.

[0003] Conventional methods for filtering food wastewater use multiple filtration devices within the wastewater tank, each comprising multiple filter assemblies connected in parallel. Because these filter units are arranged in parallel, if one filter unit fails, the internal fluid pressure significantly decreases, rendering the remaining filter units and assemblies unusable. In this case, the wastewater tank must be emptied before the filter assemblies can be inspected and replaced.

[0004] The daily output of food wastewater is high, and the filtration and treatment process is a heavy task. If the filtration equipment fails, it will seriously affect the treatment progress of this wastewater. In addition, emptying the wastewater tank is also very time-consuming, difficult and inconvenient. Utility Model Content

They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this patent. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0037] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0038] See also Figure 1 As shown, the embodiment of the present application provides a detachable and elevating filtering device 100 for filtering and treating wastewater. Specifically, the detachable and elevating filtering device 100 includes at least one filtering device 2 and a lifting device 4. The filtering device 2 is arranged in a wastewater pool 90 to be filtered, as shown in FIG. Figure 5 As shown, the filter device 2 includes one or more parallel filter assemblies 21 , and the lifting device 4 is disposed on the top of the wastewater tank 90 for detachably connecting to the filter device 2 through the top opening 91 of the wastewater tank 90 and lifting the filter device 2 .

[0039] Specifically, when filtering device 2 is performing filtering operations, it is submerged below the wastewater level. When filtering device 2 needs to be replaced, repaired, or inspected, at least a portion of filtering device 2 (e.g., at least one filter assembly 21) can be lifted above the wastewater level using lifting device 4. At this point, the portion of filtering device 2 above the wastewater level can be repaired or replaced. If a portion of filtering device 2 (e.g., at least one filter assembly 21) remains submerged below the wastewater level, the submerged portion can continue to perform filtering operations.

[0040] When existing filtration equipment and wastewater tanks are constructed, no provision is made for changing the position of the filtration equipment. The filtration equipment is fixed as a whole in the wastewater tank 90 after assembly. The wastewater tank 90 is generally also a concrete structure or a large metal part, with only an opening designed at the top for adding wastewater to be treated.

[0041] The detachable and elevating filtering device 100 provided in the embodiment of the present application is equipped with a lifting device 4 located at the top of the wastewater tank 90. ​​Through the detachable connection between the lifting device 4 and the filtering device 2, and the lifting of the filtering device 2 by the lifting device 4, at least one filtering component 21 in the filtering device 2 can be lifted above the wastewater liquid level. In this way, one or more filtering components 21 can be repaired or replaced. During the repair or replacement process, there is no need to empty the wastewater in the wastewater tank 90. ​​Other filtering components 21 or filtering devices 2 in the wastewater tank 90 can continue to work without stopping. The maintenance and replacement of the filtering device 2 are more convenient and time-consuming, which is conducive to ensuring the progress of water treatment.

[0042] For one example, see Figure 1 As shown, the detachable and elevatable filtration apparatus 100 includes multiple filtration devices 2, each of which is disposed within a wastewater tank 90 and submerged below the wastewater level to perform normal filtration operations. The multiple filtration devices 2 are arranged in parallel, and their filtration paths do not affect each other. A lifting device 4 is detachably connected to each filtration device 2, allowing the corresponding filtration device 2 to be lifted when needed.

[0043] See also Figure 5 As shown, in one embodiment, the filter device 2 further includes a bracket 27 and a connector 29. The plurality of filter assemblies 21 are detachably fixed to the bracket 27. The connector 29 is provided at the upper end of the bracket 27 and is used to connect to the lifting device 4. The bracket 27 is used to hold the plurality of filter assemblies 21 in a fixed position and allows the filter assemblies 21 to be removed from the bracket 27 in whole or in part.

[0044] For example, Figure 5 As shown, a plurality of filter assemblies 21 are arranged at intervals in the vertical direction. The filter assemblies 21 have substantially the same size and are substantially aligned in the vertical direction.

[0045] See also Figure 1 As shown, the connecting member 29 is a flexible member or a rigid member.

[0046] For example, connector 29 is a flexible member comprising a flexible connecting cord and a connecting structure attached to the connecting cord. It should be understood that the flexible member herein refers to a member that can change shape, not to a member that can be stretched or deformed when subjected to force. When not required to connect to lifting device 4, the connecting cord can be naturally positioned above filter assembly 21. When required to connect to lifting device 4, the connecting cord can be straightened.

[0047] For example, the connector 29 is a rigid member including a rigid connection structure fixedly connected to the bracket 27. The connector 29 remains fixed even when not connected to the lifting device 4. Of course, the shape and position of the connector 29 are preferably such that they do not affect the replacement and maintenance of the filter unit 210 in the filter assembly 21.

[0048] The specific form of the connecting member 29 is not limited.

[0049] For example, the connecting member 29 includes a connecting hook. In another example, the connecting member 29 includes a connecting ring.

[0050] See also Figure 6 and Figure 7 As shown, in one embodiment, each filter assembly 21 includes multiple parallel filter units 210. The filter units 210 may be filter media that physically isolate water molecules and other large-sized substances in the wastewater. The filter units 210 of each filter assembly 21 are fixed directly or at intervals to the bracket 27.

[0051] See also Figure 6 and Figure 7 As shown, in one embodiment, the filtration unit 210 includes a ceramic flat membrane 213 .

[0052] A plurality of ceramic flat membranes 213 are arranged at a certain distance to form a filter assembly 21 .

[0053] Specifically, see Figure 7 and Figure 8As shown, the ceramic flat membrane 213 includes two ceramic plates 2130 spaced apart, each of which is provided with a plurality of micropores 2135. The size of the micropores 2135 is set to allow water molecules to pass through, but not to allow other substances larger than the size of water molecules to pass through. The channel between the ceramic plates 2130 serves as the water outlet channel 2132. Adjacent ceramic flat membranes 213 are spaced apart. In this way, the wastewater to be treated is filled in the pores between the adjacent ceramic flat membranes 213, and water molecules can enter the water outlet channel 2132 through the ceramic plates 2130 of the ceramic flat membranes 213 on both sides.

[0054] See also Figure 7 As shown, the ceramic flat membrane 213 also includes a retaining structure 2131 arranged at both ends of the water outlet channel 2132, and the retaining structure 2131 is provided with a water outlet hole 2133. In addition to the water outlet hole 2133, the retaining structure 2131 closes both ends of the water outlet channel 2132 to ensure that unfiltered wastewater cannot reach the water outlet channel 2132, and the water molecules filtered through the micropores 2135 can be collected uniformly through the water outlet hole 2133.

[0055] like Figure 6 As shown, each filter assembly 21 further includes a first manifold 211 , and the water outlets 2133 of each filter unit 210 are connected in parallel to the first manifold 211 .

[0056] Please refer to Figure 5 As shown, the filtering device 2 further includes a second manifold 25 , and the water outlet ends of the first manifolds 211 are connected in parallel to the second manifold 25 .

[0057] Please refer to Figure 1 As shown, in the detachable and liftable filtering device 100 , multiple second collecting pipes 25 of multiple filtering devices 2 are arranged in parallel.

[0058] If one of the filter units 210 is damaged, such as when the ceramic plate 2130 breaks, some unfiltered wastewater will flow directly through the outlet channel 2132 and the outlet hole 2133 into the first manifold 211 and then into the second manifold 25. The filtered water collected at the ends of the multiple second manifolds 25 will become turbid. In this case, the multiple second manifolds 25 can be closed and then opened in sequence. By observing whether the filtered water remains turbid, it can be determined that the filter unit 2 has been damaged.

[0059] At this time, the filter device 2 is lifted to a suitable height by the lifting device 4, and each filter assembly 21 can be inspected to further identify the damaged filter assembly 21 and the damaged filter unit 210.

[0060] Next, see Figures 2 to 4As shown, according to the different arrangements of the filtering device 2 in the wastewater tank 90, the lifting device 4 can be arranged in different ways.

[0061] For one example, see Figures 2 to 4 As shown, the lifting device 4 includes a base 41 fixed to at least two opposite sides of the top of the wastewater tank 90, at least one crossbeam 42 mounted on the base 41, and at least one lifting member 43 mounted on the crossbeam 42. The base 41 is used to support the crossbeam 42 at a certain height, ensuring a certain height difference between the crossbeam 42 and the top of the wastewater tank 90. ​​This height difference allows at least one filter assembly 21 to be lifted above the wastewater level. The lower end of the lifting member 43 is detachably connected to the filter device 2 and is used to drive the filter device 2 up and down.

[0062] The lifting member 43 may be a structure capable of driving the filter device 2 to move in the vertical direction.

[0063] For example, in one embodiment, the lifting member 43 may include a hand chain hoist. In one embodiment, the lifting member 43 may include an electric hoist. In one embodiment, there may be multiple lifting members 43, including at least one of a manual hoist and an electric hoist.

[0064] See also Figure 4 As shown, in one embodiment, the lifting device 4 includes a plurality of beams 42 , which are fixedly distributed along a first direction X on a base 41 at intervals, and one or more lifting members 43 are fixedly provided on each beam 42 .

[0065] Specific as Figure 4 As shown, multiple (e.g., four) crossbeams 42 are fixedly arranged along a first direction X on a base 41 at intervals. Multiple (e.g., two) lifting members 43 are fixedly mounted on each crossbeam 42. Thus, the lifting device 4 includes a total of eight fixed lifting members 43. Within the wastewater tank 90, the filter devices 2 can be arranged in two rows and four columns, each corresponding to a lifting member 43. Each lifting member 43 is responsible for lifting a corresponding filter device 2.

[0066] See also Figure 2 As shown, the lifting device 4 includes one or more beams 42, each beam 42 being capable of sliding along a first direction X on a base 41, and one or more lifting members 43 being capable of sliding along a second direction Y on each beam 42. The first direction X and the second direction Y are inclined, or even perpendicular.

[0067] like Figure 2 As shown, a crossbeam 42 is provided on the base 41 , and a lifting member 43 is provided on the crossbeam 42 . Both ends of the crossbeam 42 can slide on the base 41 , and the lifting member 43 can slide on the crossbeam 42 .

[0068] The purpose of this arrangement is to eliminate the need for multiple crossbeams 42 and multiple lifting members 43, thereby reducing the number of crossbeams 42 and lifting members 43 and lowering the structural cost. In addition, in some cases, the lifting members 43 and crossbeams 42 can be moved to a suitable position so as not to affect the operation of adding wastewater to be treated through the top opening 91.

[0069] Depending on the length and structure of the base 41 along the first direction X and the length and structure of the crossbeam 42 along the second direction Y, multiple crossbeams 42 may be provided, and the movement stroke of each crossbeam 42 along the first direction X is a portion of the length of the base 41 along the first direction X. Multiple lifting members 43 may be provided, and the movement stroke of each lifting member 43 along the second direction Y is a portion of the length of the crossbeam 42 along the second direction Y.

[0070] For example, if the base 41 is relatively long along the first direction X, to prevent the central portion of the base 41 from bending excessively downward due to force, at least one support structure can be provided in the central portion of the base 41 along the first direction X. The crossbeam 42 slides along the first direction X and is limited on the crossbeam 42 by rollers clamped on the upper and lower surfaces of the base 41. The support structure prevents the rollers from sliding on the base 41. In this case, a slidable crossbeam 42 can be provided on both sides of the support structure.

[0071] For example, if the crossbeam 42 is relatively long along the second direction Y, to prevent the middle portion of the crossbeam 42 from bending downward excessively, at least one support structure is provided at the middle portion of the crossbeam 42 along the second direction Y. The support structure prevents the lifting member 43 from sliding on the crossbeam 42. In this case, the lifting member 43 can be provided on both sides of the support structure.

[0072] See also Figure 3 As shown, a plurality of beams 42 are fixedly distributed along a first direction X at intervals on the base 41 , and one or more lifting members 43 slide along a second direction Y on each beam 42 .

[0073] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
