Description

TECHNICAL FIELD

[0001] The present application relates to the field of purification tank, in particular to a chamber partition plate suitable for assembled purification tank and the purification tank. BACKGROUND

[0002] The purification tank is used for the staged treatment of decentralized domestic sewage or similar domestic sewage in the cavity, and the solid particles and soluble organic matter are removed through sedimentation separation and biological treatment. The interior of the purification tank is divided into multiple chambers by the partition plate, and the sewage is treated in stages in the chambers. The assembled purification tank can reduce the transportation volume, thereby improving the transportation efficiency, and by adjusting the position of the partition plate inside the purification tank, the chamber size can be changed.

[0003] After the sewage enters the assembled purification tank, the pre-anoxic chamber performs pretreatment to remove particles and suspended solids with a relatively large specific gravity, thereby improving the biodegradability of the sewage. Then, the sewage sequentially passes through the partition plate into the anoxic chamber, the aerobic chamber and the sedimentation and disinfection chamber. The anoxic chamber and the aerobic chamber are respectively provided with different carriers, and under the action of the biofilm of the carriers, the soluble organic matter is removed. Finally, the sedimentation and disinfection chamber is provided with a disinfection device arranged on the water pass triangular weir to disinfect the effluent. Due to the different sewage purification functions of different chambers in the purification tank, different functional components need to be installed on the partition plates of the corresponding chambers to meet the needs of water passing, filtering or blocking, etc. in the purification tank. For the assembled purification tank, the chambers are provided with partition plates of different structures to meet the functional needs of sewage purification at different stages.

[0004] At present, the partition plates of the assembled purification tank are mostly special structures, and the structures of the partition plate bases are quite different. The partition plate bases are not suitable for the installation of various functional components. On the one hand, the non-universal partition plate bases increase the production cost, and on the other hand, the partition plate slots corresponding to the purification tank need to be designed separately. A type of chamber partition plate cannot be installed in the slot area of another type of chamber partition plate, which makes it difficult to meet the needs of freely adjusting the position of the partition plate in the assembled purification tank to adjust the state of the chamber. This results in high overall cost of the assembled purification tank equipment, thereby reducing its use rate in the field of sewage treatment. SUMMARY

DETAILED DESCRIPTION

[0037] Embodiment 1

[0038] In a typical embodiment of the present application, as shown in Figures 1-13 a chamber partition plate suitable for the assembled purification tank is provided.

[0039] For the existing assembled purification tank 1, the structure of the partition plate is configured according to the function of the corresponding chamber, and the structure of the partition plate cannot be unified, so that the partition plates of different chambers can only be installed in fixed positions, which is not conducive to installing partition plates with the same structure in each chamber during actual use, resulting in high overall cost of the assembled purification tank 1, thereby reducing the use rate of the assembled purification tank 1 in the field of sewage treatment, and also having the defect of poor compression resistance.

[0040] Based on this, the embodiment provides a chamber partition plate suitable for an assembled purification tank, which adopts a unified structure of a partition plate base body 2 to improve structural consistency and increase use rate, obtains partition plates required by different chambers by opening functional holes and installing functional components on the partition plate base body 2, and improves installation convenience by using a universal plug-in structure for the edge of the partition plate base body 2, improves the strength of the partition plate by combining the recess, the protrusion and the reinforcing rib 7, and meets the multiple requirements of the assembled purification tank 1 for the partition plate.

[0041] Next, the chamber partition plate suitable for the assembled purification tank will be described in detail in combination with the drawings.

[0042] Referring to Figure 1 , the main structure of the chamber partition plate suitable for the assembled purification tank is a partition plate base body 2, which is configured with corresponding functional holes and functional components according to the arrangement position in the purification tank 1 to meet the functional requirements of the partition plate in the specified position.

[0043] A plurality of chambers need to be arranged in the purification tank 1, therefore, a plurality of partition plates are installed in the purification tank 1, the partition plates divide the purification tank 1 into a plurality of chambers, which are respectively set as a pre-anoxic chamber 13, an anoxic chamber 14, a first-stage aerobic chamber 15, a second-stage aerobic chamber 16 and a sedimentation and disinfection chamber 17. Adjacent chambers are separated by the partition plates and directly or indirectly communicated through the functional holes opened on the partition plates to meet the flow requirements during sewage treatment.

[0044] Specifically, as shown in Figure 2 and Figure 3 , one side of the partition plate base body 2 is a water-facing surface 3, and the other side is a backwater surface 4. The water-facing surface 3 faces the upstream side of the sewage flow direction in the purification tank 1, and the backwater surface 4 faces the downstream side of the sewage flow direction in the purification tank 1. The water-facing surface 3 and the backwater surface 4 are both provided with protrusions, and the adjacent protrusions form recesses. The protrusions on one side of the partition plate base body 2 correspond to the recesses on the other side of the partition plate base body 2, and the recesses on one side of the partition plate base body 2 correspond to the recesses on the other side of the partition plate base body 2.

[0045] As shown in Figure 2As shown, the convex portions distributed on the water-facing surface 3 of the baffle base 2 are main convex portions 5 and secondary convex portions 6. Two main convex portions 5 are arranged at intervals on the water-facing surface 3, and several secondary convex portions 6 are arranged between the two main convex portions 5. The main convex portions 5 and secondary convex portions 6 on the water-facing surface 3 are arranged at intervals in sequence. Reinforcing ribs 7 are provided in the recesses between the main convex portions 5 and the secondary convex portions 6, and in the recesses between the secondary convex portions 6. The shape of the reinforcing ribs 7 is adapted to the cross-sectional shape of the recess. The reinforcing ribs 7 combine with the inner wall of the recess to form a groove 8. Multiple reinforcing ribs 7 are arranged at intervals in the recess, thereby forming multiple grooves 8 that are distributed sequentially along the length direction of the recess in the groove 8.

[0046] Similarly, such as Figure 3 As shown, the back surface 4 of the partition substrate 2 has main protrusions 5 and secondary protrusions 6. Three main protrusions 5 are arranged at intervals on the back surface 4. Several secondary protrusions 6 are arranged between two adjacent main protrusions 5. The main protrusion 5 in the middle is located at the center line of the back surface 4. The main protrusions 5 and secondary protrusions 6 on the back surface 4 are arranged at intervals. Correspondingly, multiple reinforcing ribs 7 are also arranged at intervals in the recess of the back surface 4, thereby forming multiple grooves 8 arranged sequentially along the length direction of the recess in the groove 8.

[0047] In this embodiment, the cross-sectional shapes of the main protrusion 5, the secondary protrusion 6, and the concave part are all approximately trapezoidal. The reinforcing rib 7 installed in the groove 8 is an inverted trapezoidal plate, and the reinforcing rib 7 is arranged such that its plane is perpendicular to the length direction of the main protrusion 5.

[0048] By designing the structure of the water-facing side 3 and the water-returning side 4 of the baffle base 2, the strength of the baffle base 2 is improved to meet the pressure resistance requirements after installation in the purification tank 1. In addition, the length direction of the protrusion is perpendicular to the plane where the reinforcing rib 7 is located, so that it forms an approximately grid-like structure. The concave part, the protrusion, and the reinforcing rib 7 also serve as auxiliary positioning elements, which facilitates the positioning and installation of functional components on the baffle base 2, reduces the difficulty of positioning and installing functional holes and functional components, and improves processing efficiency.

[0049] Taking the partition base 2 after it is installed in the purification tank 1 as an example, the main protrusion 5, the secondary protrusion 6 and the groove 8 are all distributed vertically along the partition base 2, so that the water-facing surface 3 and the back surface 4 of the partition base 2 form concave and convex structures respectively. The circumferential edge of the partition base 2 forms an insertion part, which can match the preset insertion groove on the purification tank 1. The main protrusion 5 and the secondary protrusion 6 extend to the contact insertion part. The insertion part does not have the main protrusion 5 and the secondary protrusion 6. After the insertion part of the partition base 2 is matched with the insertion groove, the main protrusion 5 and the secondary protrusion 6 remain outside the insertion groove.

[0050] It can be understood that the main convex part 5 and the auxiliary convex part 6 are convex relative to the plane of the insertion part of the partition base body 2, the width of the main convex part 5 is greater than the width of the auxiliary convex part 6, the height of the main convex part 5 is equal to the height of the auxiliary convex part 6, and is equal to the depth of the recess. The height of the reinforcing rib 7 installed in the recess is equal to the depth of the recess. In other alternative embodiments, the dimensions of the main convex part 5, the auxiliary convex part 6, the recess and the reinforcing rib 7 can be adaptively adjusted according to actual conditions.

[0051] The length and width of the main convex part 5, the auxiliary convex part 6 and the reinforcing rib 7 not only facilitate the fitting of the flange edge of the installed functional component, but also improve the strength of the partition base body 2 to avoid phenomena such as impact fracture or deformation. The distance between the convex parts can be used as a reference for arranging functional components or opening functional holes, facilitating quick positioning and installation and improving work efficiency.

[0052] The partition base body 2 is provided with functional holes and functional components, wherein the functional holes can be rectangular holes 18 or circular holes 19 of different sizes, the arrangement position, number and form of the functional holes are adjusted according to the external components to be matched, and different functional components such as the horizontal baffle 20, the water passing baffle 23, the slag baffle 21, the water passing mesh plate 22 or the water collecting tank 24 can be installed on the partition, and the partitions can be connected in series through the air pipe 26 or the sewage return pipe 25, and part of the functional holes are provided for the air pipe 26 or the sewage return pipe 25 to pass through.

[0053] The functional holes and functional components arranged on different partition base bodies 2 are different, which meets the requirements of installing functional components in different chambers and avoids the problems of complicated production and high cost caused by multiple sets of partition base body 2 molds. It should be noted that the functional holes do not damage the overall structural strength of the partition base body 2, and do not reduce the service life of the partition body.

[0054] As shown in Figure 4 , Figure 5 , one of the partition base bodies 2 corresponds to the pre-anoxic chamber 13, and the partition base body 2 is provided with functional holes and functional components as the first partition 9.

[0056] Specifically, the first partition plate 9 is provided with a rectangular hole 18 on the backwater surface 4 of the partition plate base 2, wherein rectangular holes 18 are respectively arranged on the left and right sides of the middle main convex part 5 of the fifth horizontal row from top to bottom of the reinforcing rib 7, the distance between the two rectangular holes 18 is the distance between the auxiliary convex parts 6 on the left and right sides of the middle main convex part 5 of the backwater surface 4, the width of the rectangular hole 18 is the distance between the fifth horizontal row and the sixth horizontal row of the reinforcing rib 7 from top to bottom of the backwater surface 4, and the length of the rectangular hole 18 is the distance between the left main convex part 5 and the left auxiliary convex part 6 of the middle main convex part 5 of the backwater surface 4.

[0057] The horizontal baffle 20 is arranged one by one corresponding to the rectangular hole 18, wherein the flange edges on the left and right sides of one horizontal baffle 20 are respectively arranged on the left main convex part 5 and the middle main convex part 5 of the backwater surface 4 of the first partition plate 9, and the flange edges on the left and right sides of the other horizontal baffle 20 are respectively arranged on the middle main convex part 5 and the right main convex part 5. The length of the horizontal baffle 20 is the distance between the top end of the main convex part 5 of the backwater surface 4 and the second horizontal row of the reinforcing rib 7 from top to bottom of the main convex part 5, and the width of the horizontal baffle 20 is the distance between the two main convex parts 5 of the backwater surface 4.

[0058] The flange edges on the left and right sides of the horizontal baffle 20 are fixed on the partition plate base 2 by fixing screws and completely fit on the surface of the main convex part 5 of the backwater surface 4, which plays a role in blocking the penetration of sewage.

The length of the water passing mesh plate 22 is the distance between the right auxiliary convex part 6 of the left main convex part 5 of the backwater surface 4 and the left auxiliary convex part 6 of the right main convex part 5. The width of the water passing mesh plate 22 is the distance between the first horizontal row and the second horizontal row of the backwater surface 4. The water passing mesh plate 22 is fixed around by fixing screws and completely fits on the surface of the convex part and the reinforcing rib 7 of the backwater surface 4, thereby playing a role in blocking the carrier in the first-stage aerobic chamber 15 from flowing into the anoxic chamber 14. A circular hole 19 is formed on the right side of the upper end of the left main convex part 5 of the water surface 3 of the second partition plate 10. The diameter of the circular hole 19 is one-third of the width of the main convex part 5 of the water surface 3, thereby facilitating the installation of the gas pipeline.

[0071] The size of the water passing baffle 23 can be set to completely cover the rectangular hole 18, and the length of the water passing baffle 23 is the distance between the left auxiliary convex part 6 of the left main convex part 5 of the water surface 3 and the right auxiliary convex part 6 of the right main convex part 5 of the water surface 3, and the width of the water passing baffle 23 is the distance between the first horizontal row and the third horizontal row of reinforcing ribs 7 from top to bottom on the upper end of the water surface 3, and the upper and lower flange edges of the circular arc-shaped water passing baffle 23 are fixed on the partition plate base body 2 by fixing screws and completely adhere to the convex part of the water surface 3 and the surface of the reinforcing rib 7, thereby playing the role of blocking the carrier in the secondary aerobic chamber 16 from flowing into the sedimentation and disinfection chamber 17.

[0072] A circular hole 19 is formed in the right side of the upper end of the left side main convex part 5 of the water surface 3 of the fourth partition plate 12, and the diameter of the circular hole 19 is half the width of the main convex part 5 of the water surface 3, thereby facilitating the installation of the gas path pipe; a circular hole 19 is formed in the middle of the upper end of the right side main convex part 5 of the water surface 3 of the fourth partition plate 12, and the diameter of the circular hole 19 is the width of the main convex part 5 of the water surface 3, thereby facilitating the installation of the sewage backflow pipe 25.

[0073] Since a structure of the partition plate base body 2 is used in each chamber in the assembled purification tank 1, the overall cost of the assembled purification tank 1 product is greatly reduced; at the same time, the frequent replacement of the partition plate base body 2 mold during the production of the partition plate of the assembled purification tank 1 is avoided, which not only reduces the cost of opening multiple sets of molds, but also greatly improves the production efficiency, thereby promoting the use of the assembled purification tank 1 in the field of sewage treatment.

[0074] Example 2

[0075] In another typical embodiment of the present application, as shown in Figures 1-13 , a purification tank is given.

[0076] By using the chamber partition plate suitable for the assembled purification tank in example 1, the purification tank 1 is provided with a plug-in groove, and the plug-in part of the partition plate base body 2 is plug-in matched with the plug-in groove in the purification tank 1.

[0077] The purification tank 1 is provided with a plurality of partition plates, which are a first partition plate 9, a second partition plate 10, a third partition plate 11 and a fourth partition plate 12, and the partition plates divide the purification tank 1 into a plurality of chambers to form a pre-anoxic chamber 13, an anoxic chamber 14, a primary aerobic chamber 15, a secondary aerobic chamber 16 and a sedimentation and disinfection chamber 17 which are distributed in sequence, and the sewage is treated in stages in the chambers. The adjacent chambers are separated by the partition plates and directly or indirectly communicated through the functional holes formed on the partition plates, thereby meeting the flow demand during the sewage treatment.

[0078] The above description is merely that of the preferred embodiments of the application, and is not intended to limit the application. The application can be carried out in other variants, which will be apparent to those skilled in the art, without departing from the spirit and principles of the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the protection scope of the application.
