Description

Technical Field

[0001] This utility model relates to the field of ceramic filter membrane application technology, and in particular to a ceramic filter membrane replacement device for sewage treatment. Background Technology

[0002] Ceramic filter membranes are high-precision separation media made of inorganic ceramic materials. They are formed into a porous structure through high-temperature sintering, using pressure difference as the driving force to create cross-flow of liquid on the membrane surface to achieve filtration. They are widely used in liquid separation, impurity filtration, and wastewater treatment. Their main components are inorganic ceramic materials such as alumina, zirconium oxide, and silicon carbide, manufactured through a high-temperature sintering process. Therefore, they possess very stable physical properties and resistance to chemical corrosion, allowing them to be reused after cleaning and restoration.

[0003] When ceramic filter membranes are used for wastewater treatment, they need to be replaced periodically, depending on the nature of the wastewater, the treatment volume, and the porosity of the ceramic filter membrane. Currently, replacing ceramic filter membranes often requires shutting off the wastewater flow first, and then restarting the wastewater treatment process after the ceramic filter membrane has been replaced.

[0004] Generally, wastewater treatment often requires multi-stage filtration using numerous ceramic filter membranes. Different stages of these membranes have varying porosity. The upstream primary filtration typically uses microfiltration (>0.1μm) ceramic filter membranes, while the downstream secondary filtration requires even smaller pore sizes, such as ultrafiltration (0.01-0.1μm) ceramic filter membranes. Since ceramic filter membranes with different pore sizes filter different substances, their operating conditions are difficult to maintain consistently.

[0005] Therefore, when replacing ceramic filter membranes, not all membranes are replaced at once. Instead, each membrane is replaced individually when it reaches the replacement requirement, resulting in more frequent replacements. Furthermore, replacing the ceramic filter membrane after shutting off wastewater flow would frequently interrupt wastewater treatment, disrupting the normal process.

[0006] However, if the sewage flow is not shut off, removing the ceramic filter membrane may affect the sewage treatment effect due to its absence. Furthermore, replacing the ceramic filter membrane may cause sewage leakage, leading to adverse consequences. Utility Model Content

[0007] In view of this, the purpose of this utility model is to propose a ceramic filter membrane replacement device for sewage treatment, so as to solve the technical problem in the prior art that the replacement of ceramic filter membranes can only be carried out after the sewage flow is shut off, which affects the normal process of sewage treatment.

[0008] To achieve the above objectives, this utility model provides a ceramic filter membrane replacement device for sewage treatment, including a filter chamber installed in a sewage pipe, and the replacement device further includes;

[0009] A detachable filter unit connected inside the filter chamber, the filter unit being detached and installed via an inlet and outlet at the top of the filter chamber;

[0010] A metal base plate is slidably connected inside the filter chamber. The metal base plate is located at the bottom of the filter unit. The filter unit is also equipped with a negative pressure adsorption mechanism for adsorbing the metal base plate onto the bottom of the filter unit.

[0011] An electromagnet located at the bottom edge of the inlet / outlet is used to attract the metal base plate to seal the inlet / outlet.

[0012] Furthermore, the filtration unit includes a ceramic filter membrane and a sealing cover plate fixedly connected to the upper end of the ceramic filter membrane. The upper end of the sealing cover plate is also provided with a handle. The length and width dimensions of the ceramic filter membrane are the same as the length and width dimensions of the inlet and outlet, and the length and width dimensions of the sealing cover plate are larger than the length and width dimensions of the inlet and outlet.

[0013] Furthermore, the sewage pipe is equipped with multi-stage filtration chambers, and the ceramic filter membranes used in different filtration chambers have different pore sizes, with the pores of the ceramic filter membranes in the downstream filtration chambers becoming smaller.

[0014] Furthermore, the filter chamber is provided with multiple sets of filter units, and the filter units in the same filter chamber use ceramic filter membranes with the same pore size.

[0015] Furthermore, the outer wall of the filter chamber is provided with an electrical connector that can be connected to an external power source, and the electromagnet is connected to the electrical connector.

[0016] Furthermore, a plastic film with a thickness of 5-10 mm is connected to the bottom of the electromagnet.

[0017] Furthermore, an elastic pad is fixedly connected to the left and right sides and the bottom of the ceramic filter membrane.

[0018] Furthermore, the negative pressure adsorption mechanism includes an inner pipe disposed inside the ceramic filter membrane and the sealing cover plate. A piston is slidably connected inside the inner pipe. A connecting rod is fixedly connected to the upper end of the piston. The upper end of the connecting rod is fixedly connected to a connecting cap. The connecting cap is located above the sealing cover plate. An adsorption hole communicating with the inner pipe is opened on the elastic rubber pad at the bottom of the ceramic filter membrane.

[0019] Furthermore, a stud is fixedly connected to the connecting rod, and an internal thread is provided on the inner wall of the inner pipe, with the stud threadedly connected to the internal thread at that location.

[0020] The beneficial effects of this utility model are as follows: 1. It sets up multi-stage filtration chambers, and the ceramic filter membranes used in different filtration chambers have different pore sizes. Each filtration chamber is equipped with multiple sets of filtration units, and the filtration units in the same filtration chamber use ceramic filter membranes with the same pore size. Therefore, it can not only improve the sewage treatment effect, but also, when replacing a ceramic filter membrane, the temporary loss of a ceramic filter membrane will not have a significant impact on the sewage treatment effect, and the sewage flow does not need to be shut off.

[0021] 2. An inlet and outlet are installed at the top of the filter chamber for removing and installing the ceramic filter membrane. The length and width dimensions of the ceramic filter membrane are the same as those of the inlet and outlet, while the length and width dimensions of the sealing cover are larger than those of the inlet and outlet. Therefore, after installation, the ceramic filter membrane and sealing cover will completely block the inlet and outlet. During removal and installation, the ceramic filter membrane can block the inlet and outlet to prevent sewage leakage.

[0022] 3. A metal base plate is installed inside the filter chamber, and a negative pressure adsorption mechanism is also installed inside the filter unit to adhere the metal base plate to the bottom of the filter unit. Therefore, when disassembling the filter unit, the metal base plate can also be lifted. Thus, when the ceramic filter membrane is completely removed from the inlet and outlet, the metal base plate will block the bottom of the inlet and outlet. In addition, electromagnets at the bottom edges of the inlet and outlet are used to hold the metal base plate in place to seal the inlet and outlet. This ensures that the inlet and outlet remain sealed after the ceramic filter membrane is removed, ensuring that there is no wastewater leakage during the entire ceramic filter membrane replacement process.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when replacing ceramic filter membranes, not all membranes are replaced at once. Instead, each membrane is replaced individually when it reaches the replacement requirement, resulting in frequent replacements. If the wastewater flow is shut off before replacing the membrane, wastewater treatment is frequently interrupted, affecting the normal process. Conversely, if the wastewater flow is not shut off, removing the membrane may result in missing membranes, potentially impacting treatment effectiveness. Therefore, this design incorporates a filter chamber 102, installed at a point within the sewage pipe 101.

[0036] The filter chamber 102 is detachably connected to a filter unit 103, which can be removed and installed through the inlet and outlet 115 at the top of the filter chamber 102.

[0037] The filter unit 103 includes a ceramic filter membrane 105 and a sealing cover plate 106 fixedly connected to the upper end of the ceramic filter membrane 105. The upper end of the sealing cover plate 106 is also provided with a handle 107. The length and width dimensions of the ceramic filter membrane 105 are the same as the length and width dimensions of the inlet and outlet 115, and the length and width dimensions of the sealing cover plate 106 are larger than the length and width dimensions of the inlet and outlet 115.

[0038] Preferably, the sewage pipe 101 is provided with multi-stage filtration chambers 102, and the ceramic filter membranes 105 used in different filtration chambers 102 have different pore sizes, with the pores of the ceramic filter membranes 105 in the downstream filtration chambers 102 becoming smaller. In addition, multiple sets of filtration units 103 are provided in the filtration chambers 102, and the filtration units 103 in the same filtration chamber 102 use ceramic filter membranes 105 with the same pore size.

[0039] Therefore, it can not only improve the sewage treatment effect, but also when replacing a ceramic filter membrane 105, the temporary loss of a ceramic filter membrane 105 will not have a significant impact on the sewage treatment effect, and the sewage flow does not need to be shut off.

[0040] The second aspect of this utility model is as follows: Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, to prevent wastewater leakage during ceramic filter membrane replacement, an inlet / outlet 115 is provided at the top of the filter chamber 102 for removing and installing the ceramic filter membrane 105. The length and width dimensions of the ceramic filter membrane 105 are the same as those of the inlet / outlet 115, while the length and width dimensions of the sealing cover 106 are larger than those of the inlet / outlet 115. Therefore, after installation, the ceramic filter membrane 105 and the sealing cover 106 will completely block the inlet / outlet 115. During removal and installation, the ceramic filter membrane 105 can block the inlet / outlet 115, preventing wastewater leakage.

[0041] In addition, in this embodiment, a metal base plate 116 is provided in the filter chamber 102. The metal base plate 116 is slidably connected in the filter chamber 102 and is located at the bottom of the filter unit 103. The filter unit 103 is also provided with a negative pressure adsorption mechanism for adsorbing the metal base plate 116 to the bottom of the filter unit 103.

[0042] An electromagnet 117 is also installed at the bottom edge of the inlet / outlet 115 to attract the metal base plate 116 and seal the inlet / outlet 115. An electrical connector 104 that can be connected to an external power source is also provided on the outer wall of the filter chamber 102, and the electromagnet 117 is connected to the electrical connector 104.

[0043] Preferably, a plastic film with a thickness of 5-10 mm is also connected to the bottom of the electromagnet 117. An elastic pad 109 is fixedly connected to the left and right sides and the bottom of the ceramic filter membrane 105. A negative pressure adsorption mechanism is also provided inside the filter unit 103 to adsorb the metal base plate 116 onto the bottom of the filter unit 103. Therefore, when disassembling the filter unit 103, the metal base plate 116 can also be lifted, so that when the ceramic filter membrane 105 is completely removed from the inlet / outlet 115, the metal base plate 116 will block the bottom of the inlet / outlet 115. Additionally, the electromagnet 117 at the bottom edge of the inlet / outlet 115 is used to hold the metal base plate 116 to seal the inlet / outlet 115. This ensures that the inlet / outlet 115 is sealed after the ceramic filter membrane 105 is removed, ensuring that there is no sewage leakage during the entire replacement process of the ceramic filter membrane 105.

[0044] The negative pressure adsorption mechanism includes an inner pipe 111 disposed inside the ceramic filter membrane 105 and the sealing cover plate 106. A piston 113 is slidably connected inside the inner pipe 111. A connecting rod 112 is fixedly connected to the upper end of the piston 113. The upper end of the connecting rod 112 is fixedly connected to a connecting cap 108. The connecting cap 108 is located above the sealing cover plate 106. An adsorption hole 110 communicating with the inner pipe 111 is opened on the elastic rubber pad 109 at the bottom of the ceramic filter membrane 105.

[0045] A stud 114 is fixedly connected to the connecting rod 112. The inner wall of the inner pipe 111 has an internal thread, and the stud 114 is threaded onto this internal thread. Therefore, by simply rotating the connecting cap 108, the stud 114 rotates on the internal thread, causing the stud 114 to lift the connecting rod 112. The lifting of the connecting rod 112 then lifts the piston 113, causing the air pressure in the inner pipe 111 and the suction hole 110 below the piston 113 to drop, thereby attracting the metal base plate 116.

[0046] In summary, this utility model features a multi-stage filtration chamber 102, with different pore sizes of the ceramic filter membranes 105 used in each chamber 102. Each chamber 102 contains multiple sets of filtration units 103, and the filtration units 103 within the same chamber 102 use ceramic filter membranes 105 with the same pore size. Therefore, it not only improves wastewater treatment efficiency but also ensures that replacing a single ceramic filter membrane 105 does not significantly impact wastewater treatment performance, eliminating the need to shut off wastewater flow.

[0047] The ceramic filter membrane 105 is disassembled and installed by setting inlet and outlet 115 at the top of the filter chamber 102. The length and width dimensions of the ceramic filter membrane 105 are the same as those of the inlet and outlet 115, while the length and width dimensions of the sealing cover 106 are larger than those of the inlet and outlet 115. Therefore, after installation, the ceramic filter membrane 105 and the sealing cover 106 will completely block the inlet and outlet 115. During disassembly and installation, the ceramic filter membrane 105 can block the inlet and outlet 115 to prevent sewage leakage. A metal base plate 116 is set inside the filter chamber 102, and a negative pressure adsorption mechanism is also provided inside the filter unit 103 to adsorb the metal base plate 116 to the bottom of the filter unit 103. Therefore, when disassembling the filter unit 103, the metal base plate 116 can also be lifted. Thus, when the ceramic filter membrane 105 is completely removed from the inlet and outlet 115, the metal base plate 116 will block the bottom of the inlet and outlet 115. Additionally, an electromagnet 117 at the bottom edge of the inlet / outlet 115 is used to hold the metal base plate 116 in place to seal the inlet / outlet 115. This ensures that the inlet / outlet 115 is sealed after the ceramic filter membrane 105 is removed, preventing any wastewater leakage during the entire replacement process of the ceramic filter membrane 105.
