Description
1, technical field
The utility model relates to a kind of filter, especially a kind of self-cleaning filter.
2, background technology
The filter of prior art is broadly divided into filter-type and backwash filter type two big classes, and the former only has filtering function, and need pull down filter core during cleaning and manually clean, inconvenient operation, time-consuming taking a lot of work, and damage filter core in the cleaning process easily, maintenance capacity is big; Though the latter has the backwash filter function, but the cleaning blowdown that is in operation at any time, but complex structure, processing trouble, and cost height.
3, utility model content
In view of the deficiency that above-mentioned prior art exists, the utility model provides the self-cleaning filter that a kind of structural volume is little, processing is simple, easy for installation, cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: self-cleaning filter is by housing, water inlet, filter core, the self-cleaning mouth, delivery port, bottom and sewage draining exit are formed, its middle shell is by cylindrical shell, top board and shell flange constitute, cylindrical shell is duct-like vertical structure, top board is installed in cylindrical shell top, preparation has shell flange in the cylindrical shell bottom, by the shell flange preparation bottom is arranged in lower housing portion, bottom is made up of end socket and bottom flange, the cooperation place of bottom flange and shell flange is folded with sealing gasket, and connect by fastening bolt, water inlet is located on the cylindrical shell, and the water inlet center line is vertical with the cylindrical shell center line, the water inlet center line is symmetrically arranged with delivery port in the cylindrical shell upper edge, delivery port inserts housing by tube connector and is connected with filter core, filter core constitutes cup-shaped cylinder shape structure by filter cylinder and bottom shrouding, and on filter cylinder and shrouding the uniform filtering holes that offers, the top of filter core is installed on the top board, and on top board, offer the self-cleaning mouth, and the self-cleaning mouth is communicated in the filter core, end socket bottom at bottom is provided with sewage draining exit, and is equiped with blowoff valve at the sewage draining exit place.
During normal the operation, water inlet and delivery port are opened, self-cleaning mouth and blowoff valve are closed, current enter housing from water inlet, behind filter element filtering, flow out again from delivery port, impurity in the current is intercepted in the housing, should carry out self-cleaning when filtering holes more when the impurity of tackling in the housing or filter core is stopped up handles, at this moment, close delivery port and water inlet, open blowoff valve and self-cleaning mouth, the rinse water self-cleaning mouth of flowing through enters filter core washing and filtering hole, and the impurity in the housing discharged by sewage draining exit, reach filter core self-cleaning effect, and can realize blowdown at any time in service.
The utility model is compared than prior art, has that structural volume is little, processing is simple, easy for installation, cost is low, characteristics such as long service life and self-cleaning performance are good, and the blowdown at any time that can be in operation, and is widely used.
4, description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, housing, 2, water inlet, 3, filter core, 4, self-cleaning mouth, 5, tube connector, 6, delivery port, 7, sealing gasket, 8, fastening bolt, 9, bottom, 10, sewage draining exit, 11, blowoff valve, 101, cylindrical shell, 102, top board, 103, shell flange, 301, filter cylinder, 302, filtering holes, 303, shrouding, 901, end socket, 902, the bottom flange.
