Technical Field

[0001] The utility model relates to a filter, belonging to the technical field of filters used for strong acids and alkalis. Background Art

[0002] A filter is a device that separates impurities, particulate matter, or harmful substances from fluids through physical or chemical methods. Depending on the type of filter media, filters can be categorized as cartridge filters, bag filters, water softening filters, activated carbon filters, and quartz sand filters. These filters can remove most impurities and particulate matter from fluids, ensuring fluid cleanliness.

[0003] When replacing the filter bag of traditional bag filters on the market, the staff needs to take out the filter bag for replacement. During the replacement process, the staff has a large contact area with the filter bag, and the strong acids and alkalis remaining on the filter bag increase the harm to the human body. Therefore, it is crucial to develop a filter. Utility Model Content

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1-Figure 3 As shown, a filter includes a lower reactor 2 and an upper reactor 4, a detachable filter screen 3 is provided between the lower reactor 2 and the upper reactor 4, the upper reactor 4 is provided with a sealable cover 5, the cover 5 is provided with a feed port 6, and a discharge port 7 is provided below the lower reactor 2.

[0022] Working principle: during installation, the lower reactor 2, filter screen 3 and upper reactor 4 are fixedly connected by bolts; when replacing the filter screen 3, the bolts on the lower reactor 2, filter screen 3 and upper reactor 4 are disassembled, the filter screen 3 is taken out and replaced with a new one to achieve quick replacement. Holding the edge of the filter screen 3 for replacement can effectively reduce the contact area and reduce the hazard factor. The detachable connection of the filter screen 3 is easy to maintain and convenient to clean and replace.

[0023] The lower reactor 2 is fixedly provided with a lifter 12, which is connected to the cover 5. The lifter 12 can effectively separate the cover 5 and the upper reactor 4 from the lower reactor 2, so that the filter 3 can be replaced.

[0024] The lower reactor 2 is provided with at least four fixedly connected supporting legs 10 .

[0025] A detachably connected base 1 is provided below the lower reactor 2, and the discharge port 7 is located at the bottom of the base 1. The base 1 is detachably connected to the lower reactor 2 for easy maintenance and cleaning.

[0026] The lower reactor 2 and the base 1 are both provided with a plurality of connection holes 11. Bolts pass through the connection holes 11 to facilitate detachable connection.

[0027] The lower reactor 2, the filter screen 3, the upper reactor 4 and the cover 5 are all provided with a plurality of connection holes 11. Bolts pass through the connection holes 11 to facilitate detachable connection.

[0028] The filter 3 is a tetrafluoroethylene filter, and both sides are provided with a filter handle 9. The filter handle 9 is convenient for holding and avoids contact with strong acids and alkalis.

[0029] An overflow port 8 is provided at the upper end of the upper reactor 4 .
