Abstract

The utility model discloses an inner filter type filter, which is mainly suitable for transporting liquid containing silt and other particles, and plays the role of filtering and purifying the liquid. It includes a liquid inlet pipe 1, a lock nut 2, a sealing gasket 3, a filter upper cover 4, a filter lower cover 5, and a filter screen 6 connected with the filter upper cover 3. Its characteristics are: there is a boss on the outer wall of the liquid inlet pipe 1, which is connected with the filter cover 4 through the lock nut 2, and there is a sealing gasket 3 between the liquid inlet pipe 1 and the lock nut 2, which acts as a seal for the liquid. 6 Inside the filter lower cover 5, it is connected with the filter upper cover 4 through bolts, and the filter upper cover 4 is also connected with the filter lower cover 5 through bolts. The liquid with particles flows into the filter from the liquid inlet pipe and passes through the filter screen 6, the particles remain inside the filter screen, and the filtered and purified liquid flows out of the filter through the side outlet on the filter lower cover 5, thereby achieving the effect of filtering the particles in the liquid.

Description

an internal filter

Technical field

The utility model relates to a filter device for liquid-solid separation, which is mainly used for transporting liquid containing solid particles.

Background technique

Filters are widely used in the occasion of transporting liquids containing particles. These filters can better filter solid particles such as sediment and wooden holes in the liquid. Most of the existing filters are mostly pressure filters, such as cartridge filters. devices, vacuum filters, etc. At present, most filters isolate the particulate matter in the liquid from the outside of the filter screen through the filter screen. For example, the Chinese utility model patent of patent No. ZL97204064.1 (CN2298052Y) has just announced this filter. Outflow, the filter screen is easy to block, and many of them require complex power mechanisms. These filter equipment are mostly large and complex structures, with high energy consumption, high equipment cost, high filter cleaning cost, huge operating costs, and low economic benefits.

Contents of the invention

In order to overcome the existing disadvantages of complicated filter structure, difficulty in cleaning the filter screen, many complex power mechanisms, high energy consumption, high equipment cost, high cost of filter screen washing, huge operating costs, and low economic benefits, this utility model The novel disclosure discloses an inner filter type filter, which has the advantages of simple structure, low operating cost, convenient cleaning of the filter screen, high reusability and the like.

The technical solution adopted by the utility model to solve the technical problem is: an inner filter type filter, which is mainly suitable for transporting liquid containing particles such as sediment, and plays the role of filtering and purifying the liquid. It includes a liquid inlet pipe 1, a lock nut 2, a sealing gasket 3, a filter upper cover 4, a filter lower cover 5, and a filter screen 6 connected with the filter upper cover 4. Its characteristics are: there is a boss on the outer wall of the liquid inlet pipe 1, which is connected with the filter cover 4 through the lock nut 2, and there is a sealing washer 3 between the liquid inlet pipe 1 and the lock nut 2, which acts as a seal for the liquid. 6 Inside the filter lower cover (5), it is connected with the filter upper cover 4 by bolts, and the filter upper cover 4 and the filter lower cover 5 are also connected by bolts, and the liquid with particles flows into the filter from the liquid inlet pipe 1, After being filtered by the filter screen 6, the particulate matter remains inside the filter screen, and the filtered and purified liquid flows out of the filter through the side outlet on the lower filter cover 5, thereby achieving the effect of filtering the particulate matter in the liquid. This type of filter has the advantages of simple structure, convenient disassembly and assembly, low operating cost, convenient filter cleaning, and large filter area.

The beneficial effect of the utility model is that, compared with the existing technology, this type of filtering device has the advantages of simple structure, convenient installation, good filtering effect, large filtering area of the filter screen, and not easy to be blocked.
