The filter device is characterized in that the number of the primary filter is at least one; the primary filter is internally equipped with a filter screen; the number of the secondary filters is at least two; the secondary filters are internally equipped with filter screens and filter elements; the filter elements are mounted in the filter screens; the filter elements are quartz sand filter elements; and the filter screens are connected with the water outlets of the tanks.The device can effectively prevent silt in water from blocking a valve and a drip irrigation belt, and be widely applied to crop irrigation.

Description

A kind of drop irrigation filtering device

Technical field

The utility model relates to field irrigation technical field, particularly relates to a kind of drop irrigation filtering device.

Background technology

Shi Ge large agricultural country of China, also be the big country of lack of water simultaneously, especially in midwestern arid area, this also forces our the increasing drip irrigation technique that adopts in agricultural production, in a lot of drip irrigations water used, all carry silt, silt can stop up valve and drip irrigation zone, therefore, usually adopt a kind of simple hydrocyclone simply to process drip-irrigation water at the head end of drip irrigation zone, this method is simple, but this hydrocyclone can only be disposed the part silt in water, the water of processing is clean not enough, easily cause the obstruction of valve and drip irrigation zone, bring very large inconvenience also to people's work.

Utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of drop irrigation filtering device, comprise first order filter and the second level filter of series connection, described filter comprises tank body, screen pack, the tank body upper end of described filter is provided with delivery port, lower end is provided with water inlet, it is characterized in that, described first order filter is at least one filter, and described second level filter is at least two filters; In described first order filter, screen pack is housed; In the filter of the described second level, screen pack and filter core are housed, described filter core is arranged in screen pack, and described filter core is quartz sand filter core; Described screen pack is all connected with the delivery port of tank body.

Preferably, in described first order filter, screen pack is housed, described screen pack is stainless steel screen pack, and filtering accuracy is less than or equal to 60 orders.

Preferably, in the filter of the described second level, screen pack and filter core are housed, filter core is equipped with in described screen pack inside, and described screen pack is stainless steel screen pack, and filtering accuracy is less than or equal to 90 orders, and described filter core is quartz sand filter core.

Preferably, the top of described filter is also provided with air bleeding valve, the air pressure in controlled filter device; The water feeding pressure of described filter is more than or equal to 0.06Mpa, and backwash water feeding pressure is more than or equal to 0.16Mpa.

Preferably, described screen pack is communicated with the delivery port of tank body.

The filter process of this device: water enters from the lower end water inlet of first order filter, through the screen pack of first order filter, filter most silt and bulky grain object, water is discharged from the top of first order filter subsequently, enter second level filter, enter from filter lower end, second level water inlet, after the first order is filtered, in drainage, contained bulky grain object has been filtered most, and the filtering accuracy of second level filter is large compared to the filtering accuracy of first order filter, open air bleeding valve, ensure the inside and outside certain pressure differential of filter, the normal drainage of discharging.

The beneficial effects of the utility model are: (1) adopts the connected mode of series connection, and first order filter can filter out more than 70% silt and bulky grain object, and the filter core working time of second level filter is extended greatly; (2) compare with current existing apparatus, existing filter used after a period of time, and valve and drip irrigation zone will be stopped up, need to remove cleaning, adopt the utility model drip irrigation filter, greatly extended valve machine drip irrigation zone power lifetime, cost saving; (3) this device has been installed air bleeding valve, after the screen pack in first order filter uses a period of time, can open air bleeding valve, the pressure in controlled filter device, and the screen pack of backwash first order filter, practical.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As Fig. 1, for the utility model structural representation, a kind of drop irrigation filtering device, comprise the first order filter 1 and second level filter 2 of series connection, described filter comprises tank body 3, screen pack 4, tank body 3 upper ends of described filter are provided with delivery port 5, lower end is provided with water inlet 6, and described first order filter 1 is at least one filter, and described second level filter 2 is at least two filters; In described first order filter 1, screen pack 4 is housed; Screen pack 4 and filter core 7 are housed in described second level filter 1, and described filter core 7 is arranged in screen pack 4, and described filter core 4 is quartz sand filter core; Described screen pack 4 is all connected with the delivery port 6 of tank body 3.

In described first order filter 1, screen pack 4 is housed, described screen pack 4 is stainless steel screen pack, and filtering accuracy is less than or equal to 60 orders.

Screen pack 4 and filter core 7 are housed in the filter of the described second level, and filter core 7 is equipped with in described screen pack 4 inside, and described screen pack 4 is stainless steel screen pack, and filtering accuracy is less than or equal to 90 orders, and described filter core 7 is quartz sand filter core.

The top of described filter is also provided with air bleeding valve 8, the air pressure in controlled filter device; The water feeding pressure of described filter is more than or equal to 0.06Mpa, and backwash water feeding pressure is more than or equal to 0.16Mpa.
