Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a folded plate flocculation horizontal flow sedimentation tank. Background Technology

[0002] The working principle of the baffled flocculation sedimentation tank is based on the principles of flocculation kinetics and fluid mechanics. By setting a certain number of baffles within the flocculation tank, water containing flocculant and after thorough mixing enters the turbulent flow channels. The scaling or turning between the baffles causes boundary layer separation and generates turbulent energy dissipation. Simultaneously, the horizontal flow structure stabilizes the water flow dynamics, helping to maintain stable treatment performance. This shortens the flocculation time and improves the settling performance of the flocs, thereby achieving the desired flocculation effect.

[0003] However, after prolonged use, suspended solids, grease, and other impurities can accumulate on the surface of the baffle plates. If not cleaned in time, this can lead to blockage of the baffle plates and affect the smoothness of water flow. Therefore, a sedimentation tank that facilitates the cleaning of the baffle plates is needed. Utility Model Content

[0004] To facilitate the cleaning of the folded plates, this application provides a folded plate flocculation horizontal flow sedimentation tank.

[0005] The folded plate flocculation horizontal flow sedimentation tank provided in this application adopts the following technical solution:

[0006] A folded-plate flocculation sedimentation tank includes a flocculation tank and a horizontal flow tank connected to the flocculation tank. Multiple sets of folded-plate assemblies are installed within the flocculation tank, with gaps between adjacent sets of folded plates and positioned on opposite sides of the flocculation tank. The bottom of the flocculation tank has mounting grooves for inserting the folded-plate assemblies. The folded-plate assemblies are connected to the inner wall of the flocculation tank using expansion bolts.

[0007] By adopting the above technical solution, an installation groove for inserting the disassembly plate assembly is opened at the bottom of the flocculation tank, and one end of the disassembly plate assembly is connected to the inner wall of the flocculation tank through expansion bolts, so as to realize the detachable connection between the disassembly plate assembly and the inner wall of the flocculation tank; after the disassembly plate assembly has been used for a long time, it can be easily removed from the flocculation tank to the outside for cleaning, thus improving the convenience of cleaning.

[0008] Optionally, the folding plate assembly includes multiple folding plate units connected in sequence. The folding plate units are V-shaped. The folding plate unit at the first end is connected to the inner wall of the flocculation tank by expansion bolts. One end of the folding plate unit is provided with a plug-in block. The adjacent folding plate units are provided with plug-in slots for the plug-in blocks to be inserted. The plug-in blocks are connected to the inner wall of the plug-in slots by connecting components.

[0009] By adopting the above technical solution, the folding plate assembly is composed of multiple V-shaped folding plate units connected in sequence, which can enhance the disturbance and mixing effect of water flow; and two adjacent folding plate units are connected by interlocking slots, which can replace the folding plate unit when it is damaged, thus reducing costs.

[0010] Optionally, the connecting assembly includes a connecting bolt and a nut that mates with the connecting bolt. The insertion slot has first connecting holes on opposite sides, and the insertion block has a second connecting hole that communicates with the two first connecting holes. The connecting bolt passes through the first connecting hole and the second connecting hole.

[0011] By adopting the above technical solution, the connection of the bolt and nut can prevent the bolt from coming loose from the first and second mounting holes. The structure is simple, inexpensive, and easy for workers to assemble.

[0012] Optionally, the connecting assembly includes a connecting block, a first spring, and an unlocking component. The inner wall of the plug-in block has a connecting groove, and the connecting block is movably installed in the connecting groove. The plug-in block has a fixing groove for the connecting block to be inserted into. The first spring is used to drive the connecting block to be inserted into the fixing groove in the normal state, and the unlocking component is used to drive the connecting block into the connecting groove.

[0013] By adopting the above technical solution, the plug-in engagement between the connecting block and the fixing groove can prevent the plug-in block from detaching from the plug-in groove. Moreover, this installation method is relatively convenient and can improve the assembly and disassembly efficiency of two adjacent folding plate units.

[0014] Optionally, the unlocking component includes an unlocking rod and a guide surface. The guide surface is located on the side of the connecting block away from the insertion slot and is used to guide the connecting block into the connecting slot. The upper surface of the insertion block has an unlocking slot that communicates with the fixing slot. The unlocking rod is inserted into the unlocking slot to drive the guide surface partially into the connecting slot.

[0015] By adopting the above technical solution, when it is necessary to disconnect the connection between two adjacent folding plate units, the unlocking rod is slid into the unlocking groove so that it abuts against the guide surface and drives the guide surface of the connecting block to partially enter the connecting groove; then the plug-in block is pulled out from the plug-in groove. At this time, the guide surface abuts against the inner wall of the fixed groove, and the connecting block enters the connecting groove under the guidance of the guide surface, so as to facilitate the extraction of the plug-in block from the plug-in groove.

[0016] Optionally, a second spring is provided between the unlocking rod and the unlocking slot, and the elastic force of the second spring is used to drive the unlocking rod to move toward the side away from the unlocking slot; a detachable push rod is inserted into the unlocking slot, and the push rod is used to abut against the unlocking rod.

[0017] By adopting the above technical solution, the second spring and the unlocking rod are designed so that the unlocking rod is normally inserted into the unlocking groove, which can reduce the possibility of foreign objects entering the unlocking groove; and when it is necessary to disconnect the connection between two adjacent folding plate units, the push rod is used to abut against the unlocking rod, and the unlocking rod is pushed toward one side of the unlocking groove so that it abuts against the guide surface; thereby, the plug block can be disengaged from the plug groove.

[0018] Optionally, the inner wall of the flocculation tank is provided with a reinforcing column, the extension direction of the reinforcing column is in the same direction as the extension direction of the baffle assembly; a positioning strip is provided at the end of the baffle unit away from the insertion slot, and the reinforcing column has a positioning slot for the positioning strip to be inserted.

[0019] By adopting the above technical solution and setting up reinforcing columns, both ends of the baffle unit can be connected to the bottom of the flocculation tank and the reinforcing columns respectively, thereby increasing the stability of the baffle unit installed in the flocculation tank.

[0020] Optionally, the sidewall of the folding plate unit is provided with a baffle block.

[0021] By adopting the above technical solution and setting up turbulence blocks, the turbulence effect of the water flow can be increased, thereby improving the flocculation effect of the flocs.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By opening an installation slot at the bottom of the flocculation tank for inserting the disassembly plate assembly, and connecting one end of the disassembly plate assembly to the inner wall of the flocculation tank with expansion bolts, a detachable connection between the disassembly plate assembly and the inner wall of the flocculation tank can be achieved; after long-term use, the disassembly plate assembly can be easily removed from the flocculation tank for external cleaning, improving cleaning convenience.

[0024] 2. By setting up reinforcing columns, both ends of the baffle unit can be connected to the bottom of the flocculation tank and the reinforcing columns respectively, thereby increasing the stability of the baffle unit installed in the flocculation tank. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a folded plate flocculation horizontal flow sedimentation tank.

[0036] Reference Figure 1 A folded plate flocculation and horizontal flow sedimentation tank includes a flocculation tank 1 and a horizontal flow tank 2 connected to the flocculation tank 1. The flocculation tank 1 is provided with an inlet 11 for introducing sewage, and the horizontal flow tank 2 is provided with an outlet 21 for discharging sewage. The flocculation tank 1 is used to clump suspended solids in sewage, and the horizontal flow tank 2 helps to maintain the dynamic stability of the water flow, thereby improving the stability of sewage treatment.

[0037] Multiple baffle assemblies 3 are installed in the flocculation tank 1. All baffle assemblies 3 are spaced apart along the direction of sewage inflow to outflow in the flocculation tank 1, and two adjacent baffle assemblies 3 are respectively connected to the two inner side walls of the flocculation tank 1.

[0038] Reference Figure 2 The folding plate assembly 3 includes multiple folding plate units 31 connected in sequence. The folding plate unit 31 is V-shaped. A base 12 is provided on the inner wall of the flocculation tank 1. An installation plate is installed on the folding plate unit 31 at the first end. The installation plate is connected to the base 12 by expansion bolts 13.

[0039] Reference Figure 3The bottom wall of the flocculation tank 1 is provided with an installation groove 14, and one section of each of the baffle units 31 is inserted into the installation groove 14. By setting the installation groove 14, the contact area between the flocculation tank 1 and the baffle unit 31 can be increased, thereby improving the stability of the baffle assembly 3 in the flocculation tank 1.

[0040] The inner wall of the flocculation tank 1 is provided with a reinforcing column 4, the extension direction of the reinforcing column 4 is in the same direction as the extension direction of the baffle assembly 3; a positioning strip 42 is provided at the end of the baffle unit 31 away from the insertion slot 33, the extension direction of the positioning strip 42 is in the same direction as the extension direction of the baffle unit 31; the reinforcing column 4 has a positioning slot 41 for the positioning strip 42 to be inserted into, so that the baffle assembly 3 is installed in the flocculation tank 1 and the two ends of the baffle unit 31 are connected to the reinforcing column 4 and the mounting slot 14 respectively, further increasing the stability of the baffle assembly 3 installed in the flocculation tank 1.

[0041] Reference Figure 4 One end of the folding plate unit 31 is integrally formed with a plug-in block 32. Adjacent folding plate units 31 have plug-in slots 33 for the plug-in block 32 to be inserted into, and the plug-in block 32 is connected to the inner wall of the plug-in slot 33 through a connecting assembly 5. In this embodiment, the connecting assembly 5 includes a connecting bolt 51 and a nut 52. The plug-in slot 33 has first mounting holes 34 on both opposite side walls, and the plug-in block 32 has a second mounting hole 35 that communicates with the first mounting holes 34.

[0042] When the plug-in block 32 is fixed to the inner wall of the plug-in groove 33, the connecting bolt 51 passes through the two first mounting holes 34 and the second mounting hole 35. The nut 52 cooperates with the connecting bolt 51, so that the folding plate unit 31 is clamped between the heads of the nut 52 and the connecting bolt 51 on opposite sides, thereby preventing the plug-in block 32 from falling out of the plug-in groove 33. Moreover, this structure is simple, inexpensive, and easy for workers to assemble.

[0043] The implementation principle of Embodiment 1 of this application is as follows:

[0044] An installation slot 14 is provided at the bottom of the flocculation tank 1 for inserting the disassembly plate assembly, and one end of the disassembly plate assembly is connected to the inner wall of the flocculation tank 1 by an expansion bolt 13, which enables the disassembly plate assembly to be detachably connected to the inner wall of the flocculation tank 1; after the folding plate assembly 3 has been used for a long time, it can be easily removed from the flocculation tank 1 to the outside for cleaning, which improves the convenience of cleaning; and two adjacent folding plate units 31 are connected by the cooperation of the insertion slot 33, which can replace the folding plate unit 31 when it is damaged, which reduces costs.

[0045] Example 2:

[0046] This application discloses a folded plate flocculation horizontal flow sedimentation tank.

[0047] Reference Figure 5 and Figure 6 The difference between Embodiment 2 and Embodiment 1 is that the connecting component 5 includes a connecting block 53, a first spring 54 and an unlocking component 55. The inner wall of the insertion groove 33 is provided with a connecting groove 36, and the connecting block 53 is movably installed in the connecting groove 36. The first spring 54 is installed between the connecting block 53 and the inner wall of the connecting groove 36, and the elastic force of the first spring 54 is used to drive the connecting block 53 to move toward the side of the insertion block 32.

[0048] The plug-in block 32 has a fixing groove 37 for the connecting block 53 to be inserted. The plug-in block 32 and the fixing groove 37 can connect two adjacent folding plate units 31. This installation method is more convenient and improves the disassembly and assembly efficiency of the folding plate assembly 3.

[0049] Reference Figure 6 and Figure 7 The unlocking component 55 includes an unlocking rod 56, a push rod 57, a second spring 58, and a guide surface 59. The guide surface 59 is located on the side of the connecting block 53 away from the insertion slot 33. The side of the connecting block 53 near the insertion slot 33 is designated as a positioning surface. The distance from the guide surface 59 away from the connecting slot 36 to the positioning surface is less than the distance from the guide surface 59 near the connecting slot 36 to the positioning surface. When the insertion block 32 is fixed in the insertion slot 33, the connecting block 53 is inserted into the fixing slot 37, and the side of the connecting block 53 away from the insertion slot 33 abuts against the inner wall of the fixing slot 37.

[0050] The upper surface of the plug block 32 is provided with an unlocking groove 38 that communicates with the fixing groove 37. The unlocking rod 56 is movably installed in the unlocking groove 38 to abut against the guide surface 59. The two ends of the second spring 58 are respectively connected to the unlocking rod 56 and the inner wall of the unlocking groove 38. The elastic force of the second spring 58 is used to drive the unlocking rod 56 to move away from the unlocking groove 38 to cancel the abutment with the guide surface 59. The push rod 57 is inserted into the unlocking groove 38 to abut against the upper surface of the unlocking rod 56.

[0051] When it is necessary to cancel the connection between the connecting block 53 and the fixing groove 37, the push rod 57 is inserted into the unlocking groove 38 and abuts against the unlocking rod 56, and the unlocking rod 56 is driven to abut against the guide surface 59 of the connecting block 53, so that the connecting block 53 moves towards one side of the connecting groove 36 under the guidance of the guide surface 59, so that the guide surface 59 partially enters the connecting groove 36; so that when the plug-in block 32 is pulled out of the plug-in groove 33, the guide surface 59 abuts against the upper surface of the fixing groove 37, so that the connecting block 53 is fully entered into the connecting groove 36 under the guidance of the guide surface 59, so that the plug-in block 32 can be smoothly pulled out of the plug-in groove 33.

[0052] The implementation principle of Embodiment 2 of this application is as follows:

[0053] When it is necessary to disconnect the connection between two adjacent folding plate units 31, the unlocking rod 56 is slid in the unlocking groove 38 so that the unlocking rod 56 abuts against the guide surface 59 and drives the guide surface 59 of the connecting block 53 to partially enter the connecting groove 36; then the plug block 32 is pulled out from the plug groove 33. At this time, the guide surface 59 abuts against the inner wall of the fixing groove 37, and the connecting block 53 enters the connecting groove 36 under the guidance of the guide surface 59, so that the plug block 32 can be pulled out from the plug groove 33.

[0054] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
