Description

Technical Field

[0001] The utility model relates to the technical field of folding filters, in particular to a stainless steel folding filter element. Background Art

[0002] The field of industrial filtration equipment involves various types of filter element designs. Among them, the stainless steel folding filter element, as an important filtration component, plays a key role in liquid and gas treatment. These filter elements are usually used to filter solid particles or other impurities with different particle sizes to ensure the smooth progress of the production process and the guarantee of product quality.

[0003] Traditional stainless steel folding filter elements often face several major problems during use. One of the main problems is the difficulty of cleaning and maintenance, especially the accumulation of sand scale or impurities inside the filter element or at the connection parts. These residues not only increase the complexity of cleaning but may also cause blockage or performance degradation during equipment operation. The traditional filter element design usually requires the entire filter element to be disassembled from the equipment for maintenance, which is not only time-consuming and laborious but may also increase the production downtime and affect production efficiency.

[0004] Therefore, we have proposed a stainless steel folding filter element. Content of the Utility Model

A plurality of metal docking cylinders 2 are connected between the two groups of connectors 1. Limit annular grooves 201 are opened at both the upper and lower ends of each group of metal docking cylinders 2. A filter element mesh cylinder that telescopically adjusts inside the corresponding two limit annular grooves 201 is arranged between two adjacent metal docking cylinders 2 up and down. By stacking the lengths between the two groups of connectors 1 through a plurality of metal docking cylinders 2 and the filter element mesh cylinder, according to the relative height of the used filter tank, by increasing or decreasing the number of metal docking cylinders 2 and the filter screen cylinder body 3, it can be used to adapt to the installation inside the corresponding filter tank. At the same time, the device adopts a modular design and stacking, and the mutually docked metal docking cylinders 2 and the filter screen cylinder body 3 are installed by a multi-point thread fixing method, and can be connected and fixed in advance outside the tank body. When cleaning, the stacked metal docking cylinders 2 and the filter screen cylinder body 3 can be disassembled and cleaned. And if there is wear at some positions of the entire folding filter element, the corresponding metal docking cylinder 2 or the filter screen cylinder body 3 can be disassembled and replaced, which is convenient for daily maintenance and also saves replacement costs.

[0028] Two circles of fixing bolts 202 are arranged on the inner side of the metal docking cylinder 2. The fixing bolts 202 on each circle are threadedly connected and extended into the corresponding limiting annular groove 201. The filter element mesh cylinder includes a filter mesh cylinder body 3 and elastic stretching connecting rings 301 at both the upper and lower ends of the filter mesh cylinder body 3. Docking screw holes 302 connected to the threads of the corresponding fixing bolts 202 are provided at the edges of the connecting rings 301. Elastic connecting rings 301 at both ends of the filter mesh cylinder body 3 are inserted into the limiting annular grooves 201 inside the metal docking cylinder 2, reducing wear at the connection ends of the metal docking cylinder 2 and the filter mesh cylinder body 3 and improving the protection effect of the connection ends of the metal docking cylinder 2 and the filter mesh cylinder body 3.

[0029] One end of the metal docking cylinder 2 at the upper and lower ends is fixedly welded to one end of the corresponding connector 1. Flange rings 101 are welded at the edges of the mutually remote ends of the two connectors 1. The flange rings 101 fix the entire device inside the applied tank body through fasteners.

[0030] Among them, the width ratio of the metal docking cylinder 2 to the filter element mesh cylinder is from one to one to one to one point five. In this technical solution, the width ratio of the metal docking cylinder 2 to the filter element mesh cylinder is one to one.

[0033] Easy to clean and maintain: The modular stacked installation of the device enables easy disassembly of multiple groups of metal docking cylinders and filter mesh cylinder bodies during cleaning. This design reduces the difficulty of cleaning and maintenance, saves maintenance time, and reduces downtime, which is beneficial to the continuous operation of production equipment.

[0034] Low cost of component replacement: Components of the filter element, such as the metal docking cylinder and the filter mesh cylinder body, can be individually disassembled and replaced. Especially when wear occurs at some positions, only the damaged components need to be replaced without replacing the entire filter element. This design effectively reduces the maintenance and replacement costs and increases the economy and sustainability of the device.

[0035] Connection end protection design: The connection end design of the filter element adopts elastic connecting rings and fixing bolts, reducing wear at the connection ends and improving the connection stability and protection effect. This helps to extend the service life and performance stability of the filter element.

[0036] Improved connection stability: Through multi-point threaded fixation and welding fixation, the stability between the connector and the metal docking cylinder is enhanced, avoiding loosening or breaking during operation.
