Abstract
The utility model relates to a sand discharge type meshy filter, comprising a casing, a water inlet, a water outlet and a drain pipe, wherein the water inlet pipe is arranged in the center of the top of the casing; the water outlet is arranged in the middle of the side of the casing; the bottom of the casing is connected with the drain pipe through two branch pipes, and one branch pipe is provided with a manual control valve, and the other branch pipe is provided with an automatic control valve; a filter screen is arranged in the casing; a flow passage which is communicated with the water outlet is formed between the filter screen and the casing; a diversion body is arranged in the filter screen; the top end of the diversion body is in a circular arc shape; and a flow passage formed between the diversion body and the filter screen is communicated with the drain pipe through the two branch pipes. The utility model has the advantages of simple structure, convenient operation, low cost, long service life and convenient maintenance; since the diversion body is arranged in the filter screen, the flow in the sand discharge type meshy filter is turbulent flow, thus having good filter effect; and the filter screen is easy to clean.
Description
Technical field
The utility model relates to a kind of sewage filter device, relates in particular to a kind of sediment outflow type well strainer.
Background technology
Existing well strainer is provided with the current deflecting plate in the inside of water inlet pipe usually, by manual control, regulate the angle that current enter housing, operation is very loaded down with trivial details like this, enclosure interior is provided with impeller, blade, filter screen brush, not only complex structure, installation is loaded down with trivial details, cost is high, and because the drag effect of impeller, current are through behind the impeller, the current loss is big, continuous and the filter screen friction of filter screen brush that blade is provided with, as easy as rolling off a log damage, maintain and replace are also inconvenient, and service life is short.
The utility model content
The purpose of this utility model provides a kind of sediment outflow type well strainer, with overcome existing filtration device structure complexity, installations is loaded down with trivial details, cost is high, maintain and replace is inconvenient, the deficiency that lack service life.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of sediment outflow type well strainer comprises housing, water inlet, delivery port and blow-off pipe, and described case top center is provided with water inlet, and middle side part is provided with delivery port, and the bottom connects blow-off pipe by two branched pipes; One of them branched pipe is provided with hand control valve, and another branched pipe is provided with autocontrol valve; Enclosure interior is provided with filter screen, form a runner that is connected with delivery port between filter screen and the housing, be provided with baffle in the described filter screen, the top of baffle is circular-arc, and the runner that forms between described baffle and the filter screen is communicated with blow-off pipe by two branched pipes.
Beneficial effect described in the utility model is: simple in structure, easy to operate, cost is low, and filter screen inside is provided with baffle, can make current form turbulent flow, good filtration effect, and filter screen easily washes, and long service life is easy to maintenance.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the internal structure schematic diagram of the described sediment outflow type of the utility model embodiment well strainer.
Among the figure:
1, water inlet; 2, inspection socket; 3, baffle; 4, filter screen; 5, housing; 6, hand control valve; 7, blow-off pipe; 8, delivery port; 9, autocontrol valve 10, branched pipe.
The specific embodiment
As shown in Figure 1, the described a kind of sediment outflow type well strainer of the utility model embodiment, comprise housing 5, water inlet 1, delivery port 2 and blow-off pipe 7, described housing 5 top center are provided with water inlet 1, the sidepiece top is arranged with two inspection sockets 2, and middle side part is provided with delivery port 8, and the bottom connects blow-off pipe 7 by two branched pipes 10, a described branched pipe is provided with hand control valve 6, and another branched pipe is provided with autocontrol valve 9; Housing 5 inside are provided with filter screen 4, form a runner that is connected with delivery port 8 between filter screen 4 and the housing 5, be provided with baffle 3 in the described filter screen 4, the top of baffle 3 is circular-arc, and the runner that forms between described baffle 3 and the filter screen 4 is communicated with blow-off pipe 7 by two branched pipes 10.
During use, be respectively equipped with Pressure gauge at water inlet pipe and outlet pipe, current enter from water inlet 1, the baffle 3 of flowing through, because the effect of baffle 3, the water velocity in the runner increases, and forms turbulent flow, and impurity is short in the time that filter screen stops, and is difficult for stopping up filter screen like this; Current filter by filter screen 4, water purification is discharged from delivery port 8, and impurity then is deposited on two branched pipes 10, and whether the operator exists impurity in can judging by the pressure differential of water inlet and water outlet, thereby open autocontrol valve 9 or hand control valve 6, can discharge impurity from blow-off pipe 7.
