Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filtration device for a detachable MBR system. Background Technology
[0002] MBR, or Membrane Bioreactor system, is a wastewater treatment and reuse technology that combines biological treatment processes with membrane separation technology. Its core lies in enhancing the treatment efficiency of traditional bioreactors through the highly efficient separation of membrane modules (such as ultrafiltration and microfiltration membranes). It is widely used in municipal wastewater, industrial wastewater treatment, and reclaimed water reuse. MBR systems require filtration devices to filter the wastewater.
[0003] In current MBR systems, when the filter unit needs to be disassembled, it is removed from the MBR system by hoisting. During this process, the filter unit shakes and may collide with other equipment, which reduces the efficiency of disassembling the MBR system filter unit. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable filtration device for MBR systems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A filtration device for a detachable MBR system includes a base plate. Two slide rails are mounted on the upper surface of the base plate. The upper ends of the two slide rails are slidably connected to two square plates. Four positioning pins are movably inserted through through holes on the upper surface of each square plate. The four positioning pins on each side are fixedly connected to the corresponding slide rail. The surfaces of the two square plates are threadedly connected to two fixing bolts. The two fixing bolts on each side movably penetrate a connecting plate. Both connecting plates are in contact with the two square plates.
[0007] Preferably, the upper ends of the two square plates are respectively equipped with corresponding brackets.
[0008] Preferably, multiple membrane modules are installed inside each of the two supports.
[0009] Preferably, the upper ends of the two brackets are provided with two air inlet pipes, and the upper surfaces of the two brackets are provided with water inlet pipes.
[0010] Preferably, each of the air inlet pipes is connected to a plurality of aeration pipes, and the surfaces of the plurality of aeration pipes are provided with a plurality of exhaust holes.
[0011] Preferably, each of the brackets has four lifting holes on its surface, and each lifting hole has a corresponding lifting ring snapped into its surface.
[0012] Preferably, every two of the lifting rings are fixedly connected to both ends of a lifting rope.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. With the positioning pins and square plate, since all four positioning pins move through a square plate, when the square plate needs to be disassembled and lifted, the square plate can only move vertically upward along the positioning pins. This ensures that the filter device will not collide with other equipment when it rises, which improves the working efficiency of the filter device in the MBR system during disassembly.
[0015] 2. With the support bracket, lifting holes, lifting rings, and lifting ropes in place, when a single filter unit needs to be disassembled, the operator secures the two lifting rings of the lifting rope to the lifting holes, then secures the lifting rope to the hook of the lifting device. The external lifting device is then activated, moving the support bracket and the lower square plate off the slide rail. Since the positioning pins are fixed inside the slide rail, when the square plate is lifted, it can only move vertically upwards along the four positioning pins. This method allows the operator to easily lift the filter unit of the MBR system. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1, referring to Figures 1 to 5 A detachable MBR system filtration device includes a base plate 1. Two slide rails 2 are installed on the upper surface of the base plate 1. The base plate 1 is the bottom of the MBR tank. The slide rails 2 can fix square plates 3. The upper ends of the two slide rails 2 are slidably connected to the two square plates 3 respectively. The square plates 3 are stuck on the slide rails 2. Four positioning pins 4 are movably passed through the upper surface of each square plate 3 through through holes. The positioning pins 4 fix the position of the square plate 3. The four positioning pins 4 on each side are fixedly connected to the corresponding slide rail 2. The positioning pins 4 are fixed on the slide rail 2. The surfaces of the two square plates 3 are threadedly connected to two fixing bolts 12 respectively. The fixing bolts 12 are screwed on the square plates 3. The two fixing bolts 12 on each side movably pass through a connecting plate 11. The fixing bolts 12 fix the position of the connecting plate 11. The two connecting plates 11 are in contact with the two square plates 3. The connecting plates 11 press against the square plates 3. With the positioning pins 4 and square plate 3 in place, since all four positioning pins 4 can move through a square plate 3, when the square plate 3 needs to be disassembled and lifted, the square plate can only move vertically upward along the positioning pins 4. This ensures that the filter device will not collide with other equipment when it rises, which improves the working efficiency of the filter device in the MBR system during disassembly.
[0024] In this embodiment, corresponding brackets 5 are respectively installed on the upper ends of the two square plates 3. The brackets 5 are fixed on the square plates 3. Multiple membrane modules 6 are installed inside the two brackets 5, supporting the membrane modules 6. Two air inlet pipes 7 are respectively opened at the upper ends of the two brackets 5, and water inlet pipes 8 are opened on the upper surface of the two brackets 5. Each air inlet pipe 7 is connected to multiple aeration pipes 9. Multiple exhaust holes 10 are opened on the surface of the multiple aeration pipes 9. When the membrane module 6 needs to filter sewage, air is supplied into the air inlet pipes 7. The gas is then discharged through the vent 10 on the surface of the aeration pipe 9. The gas then causes the membrane module 6 to vibrate, preventing dirt from adhering to the membrane module 6. The water to be filtered is then discharged to the membrane module 6 through the water inlet pipe 8. The above filtration method is existing technology. Each support 5 has four lifting holes 15 installed on its surface. Each lifting hole 15 has a corresponding lifting ring 13 attached to its surface. The lifting holes 15 fix the lifting ring 13. Every two lifting rings 13 are fixedly connected to the two ends of a lifting rope 14. The lifting rope 14 pulls the lifting ring 13 upward.
[0025] The working principle of this embodiment is as follows: When it is necessary to disassemble two sets of membrane modules 6, the operator first passes two fixing bolts 12 through the same connecting plate 11, and then screws the two fixing bolts 12 into the same side of the two square plates 3, so that the connecting plate 11 is pressed against the two square plates 3. Then, the other side of the two square plates 3 is fixed in the above manner. The two supports 5 are lifted at the same time by the hoisting equipment. When it is necessary to disassemble a single filter device, the operator fixes the two lifting rings 13 of the lifting rope 14 to the lifting hole 15, and then fixes the lifting rope 14 to the hook of the lifting device. Then, the external lifting device is activated to move the support 5 and the lower square plate 3 from the slide rail 2. At the same time, since the positioning pin 4 is inserted in the slide rail 2, when the square plate 3 is lifted, the square plate 3 can only move vertically upward along the four positioning pins 4. This ensures that a single filter device will not collide with another filter device when it is disassembled.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
