Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a multi-membrane element filtering device. Background Art

[0002] Membrane elements are the separation core, consisting of a membrane. However, they lack a pressure-resistant housing and cannot be operated directly on a device. Membrane elements are typically part of small machines or instruments, and their design is based on reverse osmosis membrane elements. They are manufactured by sandwiching a flow guide layer between two flat membranes. Membrane elements play a key role in applications, particularly in water treatment systems, where their performance is influenced by multiple parameters, including water flux attenuation, salt permeability, maximum feed flow rate, minimum concentrate flow rate, and the saturation limit of sparingly soluble salts.

[0003] Although membrane technology has been widely used in existing filtration devices, some significant problems still exist, particularly in membrane replacement and filtration efficiency. In many filtration devices, the membrane installation structure is complex. The membrane is located inside the filtration device and is surrounded by numerous pipes, valves, and other structures. Replacing the membrane requires a significant amount of time to disassemble and assemble the filtration device, increasing the complexity of the operation. Due to their unique fixing method, the membranes of some filtration devices may utilize specially prepared, complex snap-on designs, which increases the difficulty of replacing the filtration device, potentially affecting production schedules and reducing production efficiency.

[0004] Most existing filtration devices lack effective dynamic stirring or shaking mechanisms, relying solely on the natural pressure of the water flow to force water through the membrane. This prevents impurities from being removed promptly from the membrane surface, easily leading to membrane clogging. When the membrane becomes clogged, the resistance to water flowing through the membrane increases, affecting the filtration rate. Therefore, this utility model addresses the issues of membrane replacement and filtration efficiency, designing a multi-element membrane filtration device. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0016] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0017] See also Figure 1 The present invention provides a multi-membrane element filtration device, which comprises:

[0018] A base 1 and a support plate 2, two of the support plates 2 are fixedly mounted on the base 1, and the support plate 2 is provided with a through opening; a shaking mechanism 3, which is mounted on the two support plates 2, and a filter box 4 is mounted on the shaking mechanism 3, and the shaking mechanism 3 is used to drive the filter box 4 to shake to speed up the filtering efficiency, and inlet and outlet are provided on both sides of the filter box 4, and a partition 5 is fixedly provided in the middle of the filter box 4, and the partition 5 is provided with a positioning groove; a water inlet mechanism 6, which is mounted on the upper end of the filter box 4, and is used to introduce sewage into the filter box 4 for filtering; a filtering mechanism 7, which is mounted in the filter box 4 and can be inserted or removed from the inlet and outlet, and is used to filter the sewage introduced into the filter box 4; a water outlet mechanism 8, which is mounted on the lower side of the support plate 2 and the water inlet end is arranged in the filter box 4, and is used to export the filtered sewage out of the filter box 4.

[0019] When using the multi-membrane element filtration device, first, the water to be filtered is introduced from the water inlet mechanism 6, and the sewage is filtered by multiple filter mechanisms 7 and then discharged from the water outlet mechanism 8. In order to improve the filtration efficiency, the shaking mechanism 3 is turned on, and the shaking mechanism 3 drives the filter box 4 to shake, thereby speeding up the filtration speed. The filtration performance of the filter mechanism 7 deteriorates after multiple filtrations, and the filter mechanism 7 can be removed from the entrance and exit for replacement.

[0020] like Figure 1As shown, as a preferred embodiment of the present invention, the shaking mechanism 3 includes: a guide rod 31, both ends of which are fixedly connected to the two support plates 2 and are provided with multiple ones, the filter box 4 is sleeved on the guide rod 31, and a reset spring 32 for pushing the filter box 4 to reset is fixedly connected between the filter box 4 and the support plate 2 on one side; a support 33, which is fixedly installed on the support plate 2 on the other side, and a power part 34 is fixedly installed on the support 33, and the output shaft of the power part 34 is fixedly connected to a cam 35 that is in sliding contact with the filter box 4.

[0021] In order to speed up the filtration rate, the power part 34 is turned on. The power part 34 is specifically a motor. The output shaft of the power part 34 drives the cam 35 to rotate. Under the elastic force of the return spring 32, the cam 35 causes the filter box 4 to swing back and forth along the guide rod 31, thereby speeding up the filtration rate.

[0022] like Figure 1 As shown, as a preferred embodiment of the present utility model, the water inlet mechanism 6 includes: a U-shaped tube 61, which is fixedly installed on the upper end of the filter box 4, and the two water outlet ends of the U-shaped tube 61 are distributed on both sides of the partition 5. A first water inlet pipe 62 is fixedly provided on the upper end of the U-shaped tube 61, and a first valve 63 installed on the U-shaped tube 61 is provided on both sides of the first water inlet pipe 62; a second water inlet pipe 64, which is fixedly installed on both sides of the U-shaped tube 61, and a second valve 65 is installed on the second water inlet pipe 64.

[0023] When filtering a single liquid, the liquid is introduced from the first water inlet pipe 62, the two first valves 63 are opened, and the second valve 65 is closed. The single liquid can be introduced into the filter box 4 through the U-shaped tube 61, and the filtering mechanism 7 can filter the water liquid. If two different liquids are to be filtered, in order to prevent the two liquids from mixing together, the two different liquids can be introduced from the two second water inlet pipes 64, the two second valves 65 are opened, and the two first valves 63 are closed. The two different liquids can be introduced from both sides of the U-shaped tube 61 into both sides of the filter box 4, thereby filtering the two different liquids.

[0024] like Figure 2 As shown, as a preferred embodiment of the present invention, the filtering mechanism 7 includes: a sealing plug 71, which is arranged in cooperation with the inlet and outlet opened by the filter box 4, and is used to close the inlet and outlet, and a handle 72 is fixedly provided on one side of the sealing plug 71; a placement groove 73, which is fixedly connected to the other side of the sealing plug 71 and is provided with a through hole, and a replaceable filter membrane 74 is provided on the placement groove 73, and the filter membrane 74 is used to filter the water flowing through; a positioning rod 75, which is fixedly connected to one end of the placement groove 73 away from the sealing plug 71, and the positioning rod 75 can be inserted into the positioning groove to maintain the stability of the placement groove 73.

[0025] When the liquid flows through the filter membrane 74, the filter membrane 74 can filter the liquid. When the filter membrane 74 needs to be replaced, pull the handle 72 to take out the placement groove 73 and the filter membrane 74 from the entrance and exit. After replacing the filter membrane 74, put the placement groove 73 and the filter membrane 74 into the entrance and exit, and insert the positioning rod 75 into the positioning groove. At this time, the sealing plug 71 can close the entrance and exit to prevent the liquid from flowing out.

[0026] like Figure 1 As shown, as a preferred embodiment of the present utility model, the water outlet mechanism 8 includes: an outlet pipe 81, which is fixedly installed on the lower side of the filter box 4, the outlet end of the outlet pipe 81 is connected to a hose 82, and the outlet end of the hose 82 is connected to a water outlet pipe 83 fixed on the support plate 2.

[0027] The filtered liquid can flow out from the outlet pipe 81 through the hose 82 and the outlet pipe 83, thereby completing the filtering process of the liquid.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
