Abstract
The invention relates to a triangular rotary filter net mechanism caoable of intaking water from exterior. According to the technical scheme provided by the invention, the triangular rotary filter net mechanism caoable of intaking water from exterior comprises a rectangular net frame and a net covered on the net frame. The triangular rotary filter net mechanism is characterized in that a triangular end plate is installed on two parallel side frames of the net frame, one edge of the triangular end plate is fixed on the side frames of the net frame, the filter net is arranged on the other two edges of the triangular end plate, and the cross section of the filter net is triangular. The triangular rotary filter net mechanism of the invention is designed into a triangular structure, so that the rigidity of the equipment is strengthened, and the equipment can not deform easily, thereby prolonging the service life of the equipment. Meanwhile, the triangular structure has large sewage storing space, the effective filtering area is increased by 15-30%, the open area is large, the pressure difference is very small, impurities can not easily hang on the filter net, the sewage clearing capacity is enhanced, and water flow conditions are improved, thereby providing advantages for normal operation of a circulating water pump. The main body of the triangular rotary filter net mechanism of the invention is made of stainless steel materials, thereby greatly prolonging the overall service life of the equipment.
Description
Technical field
The present invention relates to a kind of equipment that is used for purification of water quality and dirt collection, specifically a kind of triangular rotary filter net mechanism capable of intaking water from exterior.
Background technology
Rotary sieve is the drainage sewage disposal apparatus of water conservancy electrical engineering, thermal power plant, metallurgy, chemical industry and municipal works supply and drain water system.It can tackle and remove foreign material such as discarded in aquatic organism such as weeds in the current, leaf, fishes and shrimps and industrial or agricultural and the urban life effectively, make filtered water reach certain condition of water quality, replace manually removing contamination, reducing labor intensity, satisfy that follow-up equipment purifies water and the job requirement of water pump.This device have filter reliable, current are unimpeded, scrubbing is effective, operate steadily, noise is little, it is big to bear hydraulic pressure, safe and reliable, simple in structure, easy to maintenance, be applicable to seawater, the different water quality requirement of fresh water, use with the liquid level difference control device and can realize automation mechanized operation.
In prior art, end plate and filter screen in the rotary filter net mechanism capable are generally plane form, and its rigidity is not so good, occur distortion easily, and it is bad to cause framework to be drawn, and cleaning performance is undesirable, has a strong impact on the normal operation of water circulating pump.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide that a kind of raising is rational in infrastructure, rigidity is strong, clean-up capability is strong, refuse cleaning triangular rotary filter net mechanism capable of intaking water from exterior completely.
According to technical scheme provided by the invention, described triangular rotary filter net mechanism capable of intaking water from exterior comprises the screen frame and the filter screen that covers on the screen frame of rectangle, it is characterized in that: on two parallel frames of screen frame, triangular end plates is installed, one side of triangular end plates is fixed on the screen frame frame, filter screen is contained on the other both sides of triangular end plates, and the cross section of filter screen is a triangle.
As a further improvement on the present invention, described filter screen is by the end plate press strip and laterally press strip is fastening, the shape of end plate press strip is corresponding with the shape of triangular end plates, and the end plate press strip is fixedlyed connected with triangular end plates, and the both sides of filter screen are clipped between end plate press strip and the triangular end plates; Described horizontal press strip utilizes securing member to be fixed on the parallel frame of two other of screen frame, and the other both sides of filter screen are clipped between horizontal press strip and the screen frame.
As a further improvement on the present invention, described triangular end plates be shaped as obtuse triangle, the longest edge of triangular end plates is fixed on two parallel frames of screen frame.
As a further improvement on the present invention, described securing member is made up of connecting bolt, packing ring and attaching nut.
As a further improvement on the present invention, described screen frame, triangular end plates, filter screen, end plate press strip and horizontal press strip all adopt stainless steel material to be made.
The present invention compared with prior art, advantage is: the present invention is designed to triangular structure, and the rigidity of equipment is strengthened to greatest extent, and is not yielding, big leap ahead the service life of equipment.The dirty space of the storage of triangular structure simultaneously is big, and effective filtration area has increased 15-30%, and area of passage is big, have very little pressure reduction, foreign material are not easy to hang on the filter screen, and clean-up capability strengthens, flow condition improves, for the normal operation of water circulating pump provides advantage.Main body of the present invention adopts stainless steel material to make, and the equipment bulk life time of making is greatly improved.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the novel preferred embodiment of this reality.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: the triangular rotary filter net mechanism capable of intaking water from exterior among the embodiment is mainly by screen frame 1, triangular end plates 2, filter screen 3, end plate press strip 4, laterally press strip 5, connecting bolt 6, packing ring 7 and attaching nut 8 form.Screen frame 1 is a rectangle, one side on two parallel frames that are fixed on screen frame 1 of triangular end plates 2; The shape of described triangular end plates 2 preferably is set to obtuse triangle, and the longest edge of triangular end plates 2 is fixed on two parallel frames of screen frame 1; Filter screen 3 is contained on the other both sides of triangular end plates 2, and the cross section of filter screen 3 is a triangle.Described filter screen 3 is by end plate press strip 4 and laterally press strip 5 is fastening, and the shape of end plate press strip 4 is corresponding with the shape of triangular end plates 2, and end plate press strip 4 is fixedlyed connected with triangular end plates 2, and the both sides of filter screen 3 are clipped between end plate press strip 4 and the triangular end plates 2; Described horizontal press strip 5 utilizes the securing member of being made up of connecting bolt 6, packing ring 7 and attaching nut 8 to be fixed on the parallel frame of two other of screen frame 1, and the other both sides of filter screen 3 are clipped between horizontal press strip 5 and the screen frame 1.
The present invention can also be provided with pressure sensor respectively in the front and back of filter screen 3, during operation, the pressure reduction before and after the net is responded to by pressure sensor, when pressure differential surpasses setting value, pressure sensor sends signal and gives the PLC control module, and the PLC control module washes automatically to whole filtering net mechanism.
Filter screen 3 flow surfaces among the present invention are triangle wire sides, and effective area has increased 15-30% than conventional plane, and area of passage increases, and it is big to store up dirty space, and clean-up capability is strong, and flow condition improves, for the normal operation of water circulating pump provides advantage.Simultaneously, foreign material are not easy again to hang on the filter screen 3, have guaranteed that all area of passages are able to effective application, not network blocking, thus the dirt that is dammed on filter screen 3 can not fallen into suction chamber.
