The pressure compensating channel is provided with a water inlet communicated with the turbulent channel, and a pressure compensating unit is formed. The utility model also provides a practical processing method and a production device of the film drip irrigation belt.
Description
Technical field:
The utility model relates to and is used for required film irrigate band and production technology and the equipment of farmland droplet irrigation.
Background technology:
The exploitation of new round new agricultural technology new product at present, water-saving irrigation plays a key effect.Droplet irrigate with its water-saving, volume increase, saving of labor, province ground, strong to landform and soil suitability, can in conjunction with fertilising and fertilizer efficiency height, minimizing level land the weeding workload, be easy to automation and many-sided advantage such as pour water and extensively promoted by countries in the world, and grow continuously and fast.Developed the various types of membranes irrigate band to adapt to the needs in market for this reason.
One class film irrigate band is extrusion type internally-inlaid film irrigate band, mainly is the product of Israel, is combined in the inwall of film irrigate band (pipe) by minisize maze injection water dropper (sheet or tubular) edge.The labyrinth flow-path structural rigidity of a this class film irrigate band is good, but total length cutting back area is little, so water outlet uniformity height, and is also high to water quality requirement.
Another kind of film irrigate band is the film irrigate band of the U.S., as United States Patent (USP) US5732887; The irrigate band of introducing on the US 5957391, it is by the film seal or paste into pipe, and envelope is scalded at folded mutually place of interior adventitia or two inner membrance side direction folded mutually.The labyrinth total length of this irrigate band is long, and sectional area is big, and is lower to water quality requirement, but the water outlet lack of homogeneity.Its shortcoming is: it is not firm sometimes that (1) envelope is scalded the place; (2) it is limited to be used to the film length of producing, and replacing film frequently therefore must stop in process.
Summary of the invention
The purpose of this utility model just provides the compensation film of a kind of novel turbulent pressure irrigate band, this film irrigate band easily processes, cost is low, intensity is high, anti-stop up, evenly drip and bonding firmly.
Another purpose of the present utility model provides the production method and the process equipment of described film irrigate band.
Goal of the invention of the present utility model realizes in the following way:
This turbulent pressure compensation film irrigate band, comprise gluing turbulent flow passageway and the pressure compensation channel that forms that connect of a continuous films pipe main channel and the longitudinal folding sealing of film tube, wherein, described drip irrigation has a film tube main channel, a turbulent flow passageway and a pressure compensation channel, and form along the longitudinal folding sealing of film tube.
Described turbulent flow passageway is a labyrinth-like projection runner, the water inlet that is communicated in described film tube inner chamber main channel is arranged and be communicated in the outlet of pressure compensation channel, and form independently flow regulating unit of each sections.
Described pressure compensation channel has water inlet to be connected with turbulent flow passageway, the water stream channel that communicates with delivery port is arranged, the water stream channel cross section changes with the pressure of film tube main channel, film tube main channel pressure increases, the water stream channel cross section diminishes, film tube main channel pressure reduces, and it is big that the water stream channel cross section becomes, and forms pressure and flow-compensated.
The crowning of described turbulent flow passageway labyrinth-like projection runner contacts with the film tube main channel inwardly, when film tube main channel pressure increases, thin film tube wall compressing labyrinth-like projection runner diminishes the water stream channel cross section, film tube main channel pressure reduces, then the water stream channel cross section becomes big, forms pressure and flow-compensated.
The production equipment of described film irrigate band, the optics that it comprises the extruder (1) that forms film tube, decide external diameter to film tube are calibrated and are cut into two cutting device (4), longitudinally device (5), critical process position non-contact temperature measuring device (6), air channel cooling device (7), bosh (8), draw-gear (9), coiler device (10), the production line comprehensive detection control system (11) of the folding gluing one-tenth pressure compensation channel of sealing after control diameter device (2), labyrinth-like projection runner moulding and thermocompression bonding seal apparatus (3), the moulding.
In labyrinth-like projection runner moulding and the thermocompression bonding seal apparatus (3), vacuum negative pressure device and cooling water system are housed on the mould.
Longitudinally in the device (5) of the folding gluing one-tenth pressure compensation channel of sealing, resin glue heating extrusion device and film irrigate band thermocompression bonding seal apparatus are housed on the mould.
In the critical process position non-contact temperature measuring device (6), supporting have a cooling air control device.
The utility model compared with prior art has following advantage:
This irrigate band easily processes, cost is low, intensity is high, anti-stop up, drip evenly and bonding firmly; Adaptability to landform is strong, the quantity of the irrigate band that same arm can be arranged and length can increase greatly, and the irrigate band can processing and manufacturing get thinner, further reduced the expense of pipeline, the irrigate band amount of dripping is insensitive to variation of temperature simultaneously, can improve the uniformity of land for growing field crops water-saving irrigation.
