Abstract
Description
Technical Field
[0001] This utility model relates to the field of membrane filtration device technology, and in particular to a novel membrane filtration device. Background Technology
[0002] In the current field of membrane filtration technology, the connection methods between filter cartridges and caps in many filtration devices have significant shortcomings. Many traditional devices use flange connections or bolted connections. Taking flange connections as an example, installation and disassembly require the use of wrenches and other tools to tighten or loosen multiple bolts one by one. This process is not only tedious and time-consuming, but also requires a certain level of skill and physical strength from the operators. Especially in scenarios where filter cartridges need to be replaced frequently or the internal parts of the filtration device need to be cleaned and maintained, this connection method greatly reduces work efficiency and increases labor costs. For example, on some chemical production lines, the filtration device may need to be maintained multiple times a day. Using traditional connection methods, each maintenance may take tens of minutes or even longer, seriously affecting the continuity of production and overall efficiency.
[0003] Bolted fastening connections also have similar problems. As the service life increases, bolts may rust or loosen, leading to a decrease in the sealing performance of the connection and causing liquid leakage. This not only wastes materials but may also pollute the production environment and even cause safety accidents. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel membrane filtration device. By utilizing the cooperation of the screw-on assembly and the installation assembly, operators can replace the filter membrane cartridge, perform internal cleaning or maintenance without the need for complex tools, which greatly saves time and labor costs and improves work efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A novel membrane filtration device includes a base plate, on the upper end of which a plurality of legs are fixedly installed at equal intervals. A filter cylinder is fixedly installed on the upper end of the plurality of legs. A discharge pipe is fixedly installed on the side wall of the filter cylinder. A cylinder cover is detachably connected to the open end of the filter cylinder via a screw-on assembly.
[0007] A filter membrane cartridge is fixedly installed between the cylinder cover and the filter cartridge via an installation assembly.
[0008] A liquid storage tank is fixedly installed on the upper end of the base plate, and a centrifugal pump is fixedly installed on the side wall of the liquid storage tank. The output end of the centrifugal pump is connected to the filter cartridge through a liquid delivery pipe.
[0009] Preferably, the screw-on assembly includes a threaded ring fixedly installed on the top of the inner part of the cylinder cover, and the inner side of the open end of the filter cylinder is provided with an external thread that mates with the threaded ring.
[0010] Preferably, a first sealing groove is provided on the outer side of the open end of the filter cartridge, and a first sealing ring is embedded inside the first sealing groove.
[0011] Preferably, the mounting assembly includes a lower mounting seat fixedly mounted on the bottom of the filter cartridge, an upper mounting seat fixedly mounted on the top inner part of the cartridge cover, and the lower mounting seat communicating with the infusion tube.
[0012] Preferably, a lower mounting part is fixedly installed at the lower end of the filter membrane tube, and an upper mounting part is fixedly installed at the upper end. A second sealing ring is fitted on the outer side of both the lower mounting part and the upper mounting part.
[0013] Preferably, the lower mounting portion corresponds to the lower mounting base, and the upper mounting portion corresponds to the upper mounting base.
[0014] This utility model has the following beneficial effects:
[0015] The filter cartridge and cover are connected by a screw-on assembly. The use of a threaded ring and external threads allows for quick and easy installation and removal of the cover. This design eliminates the need for complex tools when replacing the filter cartridge, cleaning the interior, or performing maintenance, significantly saving time and labor costs and improving work efficiency.
[0016] Because the filter membrane cartridge is installed detachably between the filter cartridge and the cover, when the filter membrane becomes clogged due to prolonged use or reaches the end of its service life, a new filter membrane cartridge can be easily and quickly replaced without the need for large-scale disassembly and replacement of the entire filtration device, thus reducing operating costs and ensuring that the filtration device is always in optimal filtration condition.
[0017] A first sealing groove and a first sealing ring are provided on the outer side of the filter cartridge opening, effectively preventing liquid leakage at the connection between the filter cartridge and the cartridge cover, ensuring the sealing and stability of the filtration process. Simultaneously, second sealing rings are fitted on the outer sides of the lower and upper mounting portions of the filter membrane cartridge, respectively, tightly fitting with the lower and upper mounting seats, further enhancing the sealing of the filter membrane cartridge mounting area. This prevents liquid from bypassing the filter membrane cartridge and flowing out unfiltered, thus improving the filtration effect. Attached Figure Description
