Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an integrated agricultural water filter

BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to a filter for filtering foreign matter (sand, soil) contained in agricultural water and supplying the same to agricultural crops. More particularly, the present invention relates to a novel concept that the filter body is integrally formed,

Generally, in order to cultivate crops, the necessary water is supplied periodically. That is, crops such as vegetables or special crops cultivated in the field such as field crops or cultivated indoors such as plant crops are periodically cultivated by supplying water in an artificial manner by agricultural equipment for the period, time and proper temperature and humidity have.

In general, groundwater is used for such water, and a water supply pump (amniotic pump) is usually used for the water intake. The water taken by the water pump is supplied to a crop device through a water supply hose or a water pipe, for example, a sprinkler It is supplied to the same apparatus.

The intake of groundwater using the amphibious pump is required to filter basic filtration conditions, that is, soil, sand and other foreign substances, and directly supply the groundwater to the crops such as vegetables and special crops without filtering the water The foreign matter will accumulate on the agricultural equipments supplying the water and cause the breakdown and damage of the equipment. Therefore, the life of the agricultural equipments is ensured only when the water is supplied in the filtered state.

The filtration of foreign matter is provided by an agricultural water filter, and the agricultural water filter is composed of an upper body and a lower body which are separated and coupled, a water inlet and a water outlet are formed in the upper body, A drain valve is assembled to the lower drainage pipe, and a cylindrical filtration filter body is assembled in the upper and lower bodies.

As a prior art related to such an agricultural water filter, "Patent No. 1150957, name / agricultural water filter" has been proposed.

In the prior art, the assembly of the filtration filter body is adopted as a screw coupling method, so that the assembling work is simplified and the service life is extended by a rigid assembling structure, and the flow of the water is spirally guided, It is possible to easily discharge the water by the automatic drainage valve of the lower part in a state of falling apart, thereby prolonging the washing period of the filtration filter body, thereby maximizing ease of use.

The prior art has a structure in which the upper and lower tubular bodies separated from each other are engaged and then the band clamp is wrapped around the outer tube. However, since the injection molding is made of a synthetic resin, the assembly is exposed to sunlight for a long period of time, The upper tubular body and the lower tubular body are separated from each other in order to clean the filtration filter body, and then the tubular body is not properly assembled during the reassembling process, so that it is impossible to use the tubular tubular body and the lifetime of the product deteriorates.

In addition, it is easy to separate foreign matter of relatively large particles by inducing the flow of water spirally, but rather, foreign substances of small particles float up to the lower part due to vortex, so that they are easily attached to the filter net to advance the cleaning period of the filter filter body Resulting in inconveniences in maintenance and use.

In addition, foreign substances are trapped in the spring in the process of discharging foreign matter through the automatic drain valve, which hinders the vertical operation of the valve stem, and the opening and closing of the automatic drain valve is not smoothly performed.

In order to solve the above-described problems, the present invention provides a technique for significantly extending the service life of a product by assembling an integrated filter body by joining the upper and lower bodies to each other by heat welding.

The present invention also provides a technique for preventing vortices from being generated inside the filter body by using a plurality of vortex prevention baffles formed on the inner circumferential surface of the lower body.

The present invention also provides a technique for smoothly collecting foreign matter by rejecting foreign matter formed on the outer surface of a leakproof plug and smoothly discharging the foreign matter to the outside through a foreign matter drain pipe communicating with the foreign matter rejection.

According to the present invention, since the upper body and the lower body are joined together by thermal fusion bonding in a state where the upper body and the lower body are engaged with each other, the phenomenon such as deformation and warping occurring at the assembly site is fundamentally cut off, The user can conveniently remove the cover cap from the lower end of the cover assembly and then remove the filter assembly.

Further, the present invention provides the effect of increasing the cleaning cycle of the filter assembly by preventing the occurrence of vortexes in a plurality of vortex prevention baffles formed on the inner circumferential surface of the lower body, thereby preventing foreign matter from sticking to the filter net.

In addition, since the foreign matter collected by the foreign matter removing unit is smoothly discharged to the outside through the foreign matter drain pipe communicating with the foreign matter removing unit formed on the outer peripheral surface of the filter support, the foreign matter drain pipe is not clogged, Lt; / RTI >
