Abstract
The utility model relates to a blocking preventing filter which is suitable for a pesticide sprayer, and a circular spongy body and gratings are arranged in a spherical shell. The effective filtration area is a multiple of sectional area of a rubber pipe and the cellular filtering of the entire spongy body, so the water quality can be purified, and the problem of the spraying hole easy blocking by impurities can be solved. The utility model has safe and convenient operation, which is suitable for low volume spraying.
Description
The utility model is the filter about the anti-blocking usefulness of pesticide spray.
The sprayer that is used for spraying insecticide stops up spray gun for preventing the soup suspended impurity, makes soup remove impurity by a filter earlier usually before entering spray gun.In the prior art, this filter is a tubular filter net, and it is loaded in the pipe of the sebific duct of sprayer and spray gun link.Because the filter screen filter opening is bigger, and effective filtration area is less, so filter effect is relatively poor, cause minute impurities still can enter spray gun by filter opening, cause spray orifice to stop up, especially use micropore ozzle disc or micropore to revolve the water device and carry out low-gallonage spraying, the easier obstruction of spray orifice.Get rid of spray orifice and stop up not only time-consumingly, and increased that human body directly contacts medicine and the possibility of poisoning.
In view of the foregoing, the purpose of this utility model provides a kind of safe in utilization, convenient, and the anti-block filtering device of good filtration effect thoroughly solves the easily stifled problem of spray orifice.
For achieving the above object, the utility model adopts sponge to replace porous filter screen to increase thickness of filter bed and filter opening density.Concrete scheme is, filter comprises a spherical shell that has inlet tube m and outlet n, certain thickness sponge filter course (2) is housed in this spherical shell, for preventing the excessive sponge torsional deformation that causes of hydraulic pressure, the exporter of this filter in housing is provided with lattice-shaped or cavernous fence (5), works to block and support sponge.For making this device be convenient to install and clean, spherical shell is formed to be threaded by two hemisphere (1) and (4), and the centre seals with packing ring (3).This filter by the external screw thread on the internal thread on the inlet tube m and the outlet n respectively with sprayer air chamber (6) on water out adapter (7) and the nut (9) of sebific duct (8) front end be connected.
The utility model filter is because of being connected between air chamber (6) and the sebific duct (8), be not subjected to the restriction of sebific duct sectional area, therefore suitably increase the diameter of housing and sponge, compare with the existing screen pack that is loaded in the sebific duct, not only effective filtration area is big, and the sponge pore density is big, certain thickness is arranged, form whole micropore, thereby under the effect of air chamber pressurization, soup can be smooth and easy flow through and by high purification, solved the easily stifled problem of spray gun, and this filter is installed, cleaned and to change sponge very convenient.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is the profile of present embodiment filter.
Fig. 2 is present embodiment filter scheme of installation on sprayer.
Number in the figure is respectively:
1,4-hemispherical shell, 2-spongy layer, 3-packing ring, 5-fence, 6-air chamber, 7-air chamber water out adapter, 8-sebific duct, 9-nut, m-inlet tube, n-outlet.
The spherical shell of present embodiment and fence can metal or plastics make.
The housing of the utility model filter is not limited to sphere, also can be designed to cylindrical or other shape.
Claims (2)
1, the filter of the anti-blocking usefulness of a kind of pesticide sprayer is characterized in that, a spherical hull shape that has inlet tube m and outlet n is arranged, and is provided with sponge filter course (2) and fence (5) in the housing.
As the described filter of above-mentioned claim 1, it is characterized in that 2, spherical shell is formed to be threaded by two hemisphere (1) and (4).
