Abstract
The utility model relates to a grit filter comprising a filter body which is provided with a support at the bottom. The grit filter is characterized in that the interior of the filter body is divided into a plurality of cavities through clapboards; the top of each cavity is provided with a water inlet, the bottom of each cavity is provided with a water outlet, each cavity is internally provided with baffles which are arranged in a step manner, and a plurality of filter caps are uniformly distributed on the baffles which are connected with the clapboards. According to the utility model, a trapezoid cross section is adopted for filtering water, so that the area of a water filtering cross section is increased, the filtering flow of a system is greatly increased, the size of the grit filter is reduced, and materials are saved.
Description
Technical field
The utility model belongs to the agricultural water-saving irrigation equipment technical field, relates in particular to a kind of sandrock filter.
Background technology
At present, the stem Device Filters with the supporting application of drip irrigation system has centrifugal type filter, sandstone formula filter, well strainer, laminated filter.Different according to water quality, with the filter set of several kinds of structures altogether, form two-stage, the filtration more than three grades so as to realize precisely, high efficiency filter, guarantee the irrigation system clean water quality, douche is not blocked.Sandrock filter is used for irrigating the primary filter equipment with earth surface water source (reservoir, dyke, irrigation canals and ditches, lake, river and other exploitation water source), is used for the dried up algae of branch, planktonic organism, organic impurities etc.
Sandrock filter often utilizes aggregate grading to form a 3 D stereo filter core, when current through out-of-date, particle and organic matter are adsorbed on the sandstone surface in the water, reach the filtration purpose.When the sandrock filter inflow-rate of water turbine greater than 200m
3/ s, the sandrock filter volume is bigger than normal, and cost is high, brings difficulty for transportation and maintenance, and the bottom adopts horizontal baffle and attach the filter cap and carry out water outlet, and the cross-section of river is little, and inflow-rate of water turbine is little.Therefore, how through changing the structure of sandrock filter, dwindle the volume of sandrock filter, the inflow-rate of water turbine that increases sandrock filter just seems very important.
The utility model content
The utility model technical problem to be solved provide a kind ofly be convenient to process, volume is little, inflow-rate of water turbine is big sandrock filter.
For addressing the above problem, the described a kind of sandrock filter of the utility model comprises that the bottom is provided with the filter body of bearing, is characterized in that: be separated into several cavitys through dividing plate in the said filter body; The top of each said cavity is provided with water inlet, and its bottom is provided with delivery port, is provided with the baffle plate that is trapezoidal layout in it, is evenly equipped with several filter caps on this baffle plate, and links to each other with said dividing plate.
Said baffle plate links to each other with said filter body edge with said dividing plate.
The utility model compared with prior art has the following advantages:
1, owing to adopt the trapezoid cross section to cross water in the utility model, increases discharge section area, promptly increased the quantity of filter cap, therefore, improved the inflow-rate of water turbine of system greatly, dwindled the volume of sandrock filter, practiced thrift material.
2, the utility model is simple in structure, production cost is low, easy to process.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the backsight structural representation of the utility model.
Fig. 2 is the left TV structure sketch map of the utility model.
Among the figure: 1-cavity 2-dividing plate 3-filter cap 4-baffle plate 5-bearing.
The specific embodiment
Like Fig. 1, shown in Figure 2, sandrock filter comprises that the bottom is provided with the filter body of bearing 5.Be separated into several cavitys 1 through dividing plate 2 in the filter body; The top of each cavity 1 is provided with water inlet, and its bottom is provided with delivery port, is provided with the baffle plate 4 that is trapezoidal layout in it, is evenly equipped with several filter caps 3 on this baffle plate 4, and links to each other with dividing plate 2.
Wherein: baffle plate 4 links to each other with the filter body edge with dividing plate 2.
Claims (2)
1. a sandrock filter comprises that the bottom is provided with the filter body of bearing (5), is characterized in that: be separated into several cavitys (1) through dividing plate (2) in the said filter body; The top of each said cavity (1) is provided with water inlet, and its bottom is provided with delivery port, is provided with the baffle plate (4) that is trapezoidal layout in it, is evenly equipped with several filter caps (3) on this baffle plate (4), and links to each other with said dividing plate (2).
2. a kind of sandrock filter as claimed in claim 1 is characterized in that: said baffle plate (4) links to each other with said filter body edge with said dividing plate (2).
