Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flat-plate ceramic membrane wastewater filtration treatment device. Background Technology

[0002] Flat-plate ceramic membranes are a novel water treatment technology made from high-tech materials, exhibiting excellent filtration performance and stability. Primarily composed of ceramic materials such as alumina and zirconium oxide, they possess wear resistance, corrosion resistance, high-temperature resistance, and oxidation resistance, enabling them to adapt to wastewater treatment needs in various harsh environments. Wastewater treatment ceramic flat-plate membranes have a unique filtration mechanism, with micron-level pores distributed on their surface, effectively intercepting suspended solids, microorganisms, organic matter, and other impurities in wastewater, achieving highly efficient water purification. Furthermore, their smooth surface is not easily clogged, exhibiting strong anti-fouling capabilities and maintaining stable filtration performance over a long period.

[0003] Flat-plate ceramic membrane filtration systems require periodic disassembly and reassembly of the ceramic membrane modules for deep cleaning, inspection, and maintenance. However, commonly used ceramic membrane modules are typically fixed to supports on the inner wall of the water treatment tank using fasteners. This not only makes disassembly and reassembly cumbersome but also disrupts normal wastewater filtration during these processes, thus affecting wastewater treatment efficiency. Utility Model Content

The top surface of the water-passing cylinder has a centrally located top hole that matches the top of the plug. The top of the push rod assembly is threadedly sleeved on the middle of the top surface of the frame and the bottom end is sleeved in the first top hole. The bottom end of the push rod assembly is slidably sleeved with the second top hole.

[0006] Preferably, a top plate is fixed to the top surface of the frame, and a plurality of rectangular frames are fixedly fitted onto the top surface of the water treatment tank, which are vertically sliding and matched with the frame.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a flat-plate ceramic membrane wastewater filtration treatment device. An inlet connector 1.1 is fitted onto the top of the rear wall of a water treatment tank 1, and an outlet connector 1.2 is fitted onto the bottom of the front wall. A partition 1.3 extending horizontally is provided within the inner cavity of the water treatment tank 1, corresponding to the position above the outlet connector 1.2. Multiple rectangular frames 1.4 are fixedly fitted onto the top surface of the water treatment tank 1, arranged in a rectangular array. A sleeve hole 1.3.1 is provided on the partition 1.3 at the center of each rectangular frame 1.4, and multiple threaded holes are provided circumferentially around the sleeve holes 1.3.1 on the partition 1.3.

[0024] The ceramic membrane module 2 includes a frame 2.1 that slides and matches the rectangular frame 1.4, ceramic membrane plates 2.2 embedded in the front and rear ends of the cavity of the frame 2.1, and a bottom cylinder 2.5 fixedly sleeved in the middle of the bottom surface of the frame 2.1. The bottom cylinder 2.5 has a top hole 2.5.1 in the center of its top surface. A top plate 2.3 is fixed to the top surface of the frame 2.1, and the outer edge of the bottom surface of the top plate 2.3 is supported on the top surface of the rectangular frame 1.4. A circular groove 2.3.1 is provided in the middle of the top surface of the top plate 2.3, and an internally threaded sleeve 2.4 is fixedly sleeved in the middle of the bottom surface of the circular groove 2.3.1.

[0025] The water-passing connector 3 includes a water-passing cylinder 3.1 that fits into the bottom of the inner cavity of the bottom cylinder 2.5 and also fits into the sleeve hole 1.3.1; a fixing ring 3.2 fixed to the bottom of the inner cavity of the water-passing cylinder 3.1; a spring 3.3 supported in the middle of the top surface of the fixing ring 3.2; and a plug 3.4 fixed to the top of the spring 3.3. The top surface of the water-passing cylinder 3.1 has a centrally located top hole 3.1.1 that fits into the top of the plug 3.4. A connecting ring 3.1.2 is fixed to the middle of the outer peripheral wall of the water-passing cylinder 3.1, and is bolted to the partition plate 1.3. A central post 3.2.1, which fits into the bottom of the spring 3.3, is located in the middle of the inner cavity of the fixing ring 3.2. A strip 3.2.2 is fixedly connected between the bottom of the central post 3.2.1 and the inner peripheral wall of the fixing ring 3.2. That is, when the water-passing connector 3 is idle, the spring 3.3 pushes the plug body 3.4 upward, so that the top hole 3.1.1 is blocked.

[0026] The push rod assembly 4 includes a circular plate 4.4 that fits into the circular groove 2.3.1, a threaded post 4.1 fixed to the center of the bottom surface of the circular plate 4.4 and threadedly fitted into the internal threaded sleeve 2.4, a rod 4.2 whose top end abuts against the center of the bottom surface of the threaded post 4.1, and a plug 4.3 fixed to the bottom end of the rod 4.2 and slidably fitted into the first top hole 2.5.1 and the second top hole 3.1.1. A handle 4.5 is fixed to the top surface of the circular plate 4.4. That is, under normal circumstances, the plug 4.3 is located inside the first top hole 2.5.1 to achieve the effect of sealing the first top hole 2.5.1.

[0027] In summary, during use, wastewater enters the upper part of the inner cavity of the water treatment tank 1 through the inlet connector 1.1. When installing the ceramic membrane module 2, the bottom cylinder 2.5 is fitted onto the top of the corresponding water passage cylinder 3.1. By rotating the circular plate 4.4 through the handle 4.5, the circular plate 4.4 drives the threaded column 4.1 to rotate relative to the inner threaded sleeve 2.4. The top rod assembly 4 moves downward as a whole, causing the plug 4.3 to press down on the plug body 3.4. The plug body 3.4 then compresses the spring 3.3 and retracts into the inner cavity of the water passage cylinder 3.1. The outer diameter of the rod body 4.2 is smaller than the diameter of the top hole 1 2.5.1 and the top hole 2 3.1.1, so that the inner cavity of the frame 2.1 is connected to the cavity on the lower side of the partition plate 1.3. That is, after being filtered by the ceramic membrane plate 2.2, the wastewater enters the cavity on the lower side of the partition plate 1.3 through the top hole 1 2.5.1 and the top hole 2 3.1.1 in sequence, and then is discharged through the outlet connector 1.2.

[0028] When it is necessary to remove the ceramic membrane assembly 2, the handle 4.5 is rotated in the opposite direction to the entire push rod assembly 4, so that the entire push rod assembly 4 moves upward, that is, the plug 4.3 is retracted into the top hole 2.5.1, and the spring 3.3 pushes the plug 3.4 upward again, so that the top hole 3.1.1 is closed.

[0029] Then, lift the ceramic membrane assembly 2 upwards using handle 4.5.

[0030] In order to facilitate the uniform distribution of wastewater within the water treatment tank 1, an overflow trough 1.5 is fixed on the inner wall of the water treatment tank 1 at the position below the water inlet connector 1.1.
