Description

Technical Field

[0001] This utility model relates to the field of liquid filter technology, specifically a low-resistance, high-flow-rate liquid filter. Background Technology

[0002] To prevent impurities from clogging the pipelines transporting liquids such as battery paste or affecting the normal operation of water pumps, a pipeline filter is usually installed at the inlet of the centrifugal pump. Water flows through the filter screen inside the filter and flows out after being filtered, thus completing the filtration process. Liquid filters are an indispensable device in pipelines transporting media. They are typically installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media, protecting the valves and equipment. When fluid enters the filter cartridge containing a filter screen of a specific size, impurities are blocked, while clean filtrate is discharged from the filter outlet. When cleaning is required, simply remove the detachable filter cartridge, clean it, and reinstall it. Therefore, use and maintenance are extremely convenient.

[0003] A prior art low-resistance filter, patent application number 202321489040.8, includes a housing and a filter screen disposed within the housing. One end of a second filter section is connected to the water outlet via a filter cover, and the outer wall of the second filter section and the inner wall of the housing form a receiving cavity, which communicates with the water outlet. This invention ensures effective filtration of the water flow while reducing the filter's resistance to the water flow. However, the filtration effect of a single filter cartridge is generally poor, and it is inconvenient to inspect and clean the filter cartridge. Utility Model Content

[0004] The purpose of this invention is to provide a low-resistance, high-flow-rate liquid filter to solve the problems of the general filtration effect of a single filter cartridge in the prior art, and the inconvenience of filter cartridge maintenance and slag removal and cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-resistance, high-flow-rate liquid filter, comprising a machine base, a slag storage seat on the upper side of the machine base, a sealing ring on the opening at the upper part of the slag storage seat, an installation plate inserted into the upper part of the slag storage seat, a plurality of filter cylinders on the upper side of the installation plate via connecting seats, and each filter cylinder having an inlet pipe and an outlet pipe at its lower end, one end of the two inlet pipes being connected to a main inlet pipe via a connector, and one end of the two outlet pipes being connected to a main outlet pipe via a connector, and adjacent outlet pipes and inlet pipes being connected via connecting pipes, and two transverse sliding blocks on one side of the machine base via opposing threaded screws, with transverse sliding supports on the upper side of the two transverse sliding blocks, and a clamping bolt for pressing down the top of the installation plate on the upper middle part of the transverse sliding supports.

[0006] Furthermore, the lower end of the machine base is provided with a lower support, and the lower support is provided with pulleys at the four corners on the lower side.

[0007] Furthermore, the number of filter cartridges is one or more, the filter cartridges are provided with an inner filter cartridge inside, and the top of the filter cartridges is also provided with an exhaust valve.

[0008] Furthermore, the lead screw is rotatably mounted in a limiting groove on the side wall of the machine tool, and the two ends of the lead screw are provided with two opposite sets of external threads.

[0009] Furthermore, one end of the lead screw is provided with an adjustment handle, and the internal thread of the adjustment handle is provided with a locking bolt.

[0010] Furthermore, the lower end of the clamping bolt is provided with a pressure plate via a bearing seat and a bearing, and the outer diameter of the pressure plate is larger than the outer diameter of the clamping bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features multiple filter cartridges mounted on the mounting plate via connecting seats. Each filter cartridge has an inlet pipe and an outlet pipe at its lower end. Two inlet pipes are connected to a main inlet pipe via connectors at one end, and two outlet pipes are connected to a main outlet pipe via connectors at one end. Adjacent outlet pipes and inlet pipes are connected via connecting pipes. By connecting multiple inlet and outlet pipes to the main inlet pipe, connectors, connecting pipes, and main outlet pipe, filter cartridges are connected in series and then in parallel, achieving low-resistance, high-flow-rate filtration of battery slurry liquid. The filtration effect is good, and the structure is compact, making it easy to move and use.

[0013] 2. This utility model features a slag storage seat on the upper side of the machine platform, with a sealing ring at the opening of the upper part of the slag storage seat. An installation plate is inserted into the upper part of the slag storage seat, and multiple filter cylinders are installed on the upper side of the installation plate via connecting seats. It adopts an insert-type installation structure, which makes installation convenient and quick, and facilitates maintenance and slag removal and cleaning.

[0014] 3. In this utility model, two transverse sliding blocks are provided on one side of the machine base via opposing screw threads, and transverse sliding brackets are provided on the upper side of the two transverse sliding blocks. A clamping bolt is provided in the middle of the upper part of the transverse sliding bracket for pressing down the top of the mounting plate. By rotating the clamping bolt, it is pressed onto the upper part of both ends of the mounting plate, which is used to press and fix the mounting plate inserted on the upper part of the slag storage seat, thereby improving the stability of the mounting plate installed on the slag storage seat. At the same time, rotating the clamping bolt in the opposite direction disengages it from the mounting plate, and then rotating the screw causes the transverse sliding bracket to move laterally out of the upper part of the slag storage seat, thereby facilitating the disassembly of the mounting plate and the filter cylinder above it.

[0020] 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.

[0021] Please see Figure 1 , Figure 2 , Figure 3In this embodiment of the present invention, a low-resistance, high-flow-rate liquid filter includes a machine base 1. A lower support 2 is provided at the lower end of the machine base 1, and pulleys 22 are provided at the four corners of the lower side of the lower support 2 for easy movement and transport of the equipment. A slag storage seat 3 is provided on the upper side of the machine base 1. A sealing ring 7 is provided at the opening at the upper part of the slag storage seat 3. An installation plate 4 is inserted into the upper part of the slag storage seat 3. Multiple filter cylinders 5 are provided on the upper side of the installation plate 4 via connecting seats 6. The number of filter cylinders 5 is 4 or 6. An inner filter cylinder 20 is provided inside the filter cylinder 5. An insertion-type installation structure is adopted, which is convenient and quick to install and facilitates maintenance and slag removal of the filter cylinders 5. The filter cartridge 5 is clean, and each filter cartridge 5 is equipped with an inlet pipe 16 and an outlet pipe 21 at its lower end. One end of each inlet pipe 16 is connected to an inlet manifold 17 via a connector, and one end of each outlet pipe 21 is connected to an outlet manifold 18 via a connector. Adjacent outlet pipes 21 and inlet pipes 16 are connected by a connecting pipe 19. Through multiple inlet pipes 16 and outlet pipes 21, the filter cartridges 5 are connected in series and then in parallel via the inlet manifold 17, connector, connecting pipe 19 and outlet manifold 18, thereby achieving low-resistance, high-flow-rate filtration of battery slurry liquid. The structure is compact and easy to move and use.

[0022] like Figure 1 and Figure 2 As shown, to improve the stability of the mounting plate 4 on the slag storage seat 3, two transverse sliding blocks 10 are provided on one side of the machine base 1 via opposing threads of the lead screw 9, and a transverse support 11 is provided on the upper side of the two transverse sliding blocks 10. The other side of the transverse support 11 is also slidably connected to the other side of the machine base 1 via a guide rod and a slider. The lead screw 9 is rotatably set in the limiting slide groove 8 on the side wall of the machine base 1, and two sets of opposite external threads are provided at both ends of the lead screw 9.
