Abstract
The W-shaped water filter for large thermal power plant and nuclear power plant includes one cylinder with water inlet, water outlet and pollutant discharge port; one filter element; one pollutant discharge mechanism; one driving mechanism and one main shaft. It features the filter element, which has W-shaped axial section, comprises a skeleton and nets attached to the skeleton, and has ends set on the cylinder; the main shaft, which is installed in the center of the filter element and has one end connected to the drive mechanism and the other end with at least one pollutant discharge mechanism; and the pollutant discharge mechanism, which has one end contacting closely to the W-shaped filter element and is connected to the drainage pipe. The present invention has great flow capacity, small rotation inertia, small gap, low power consumption, and other advantages.
Description
Technical field the present invention relates to a kind of water filtering device, is the filter that is used for large thermal power plant and nuclear power station water, a kind of specifically W shape filter.
Background technology in the prior art, the filter of large thermal power plant and nuclear power station water is that people know.It is to remove attached to the foreign material on the filter core wire side by the backwash of fluid.This filter plant major defect is: owing to be to rotate blowdown by filter core, rotary inertia is big, and driving power is big, and the through-flow multiplying power of filter core is low, and resistance to water-flow is big, and filter effect is undesirable; Volume is big, the manufacturing cost height.
The summary of the invention the technical problem to be solved in the present invention provides a kind of W shape filter, little, the through-flow multiplying power of this filter rotary inertia is big, device volume reduces, compact conformation, easy to maintenance, driving power reduces, energy savings, particularly this device has adopted the strong pollutant-removing system that has the brush of removing contamination, and it is effective to remove contamination, and saves the water yield.
In order to solve the technical problem, the technical solution used in the present invention is: a kind of W shape filter, comprise cylindrical shell, and cylindrical shell is provided with water inlet, delivery port, sewage draining exit, filter core, blowdown mechanism, and transmission mechanism and main shaft; It is characterized in that: the axial section of filter core is W shape, and this W shape filter core is made up of skeleton and the wire side that is attached on the skeleton; The two ends of filter core are installed on the cylindrical shell; The filter core center is equipped with main shaft, and transmission mechanism links to each other with an end of main shaft, fixed installation at least one cover blowdown mechanism on the other end of main shaft, and an end of blowdown mechanism is close on the W shape filter core, and blowdown mechanism is connected with blow-off pipe.
Course of work summary of the present invention: power drive mechanism drives main axis rotation, because blowdown mechanism is fixedly installed on the main shaft, in the time of main axis rotation, blowdown mechanism and main shaft rotate synchronously, the Dirt-cleaning brush of blowdown mechanism is close to net tube inner surface on the W shape filter core around main axis rotation, foreign material that stick to net tube surface is flaked off in the feculence box, because of feculence box is connected with blow-off pipe, the foreign material of institute's filtering are concentrated to blow-off pipe and discharge, the conserve water resource.
The present invention has thoroughly solved the deficiency of traditional filtering device, and following advantage is arranged compared with the prior art:
1, transmission mechanism drives the Dirt-cleaning brush rotation, rather than drives the filter core rotation, thereby rotary inertia is little, driving power is little, energy savings, and also torque do not receive the influence of pressure reduction before and after the filter screen, and fault rate is low, and is safe and reliable;
2, adopt W shape filter core, than the filter table area increase of straight barrel shape filter core, through-flow multiplying power increases, and the filter volume reduces, and saves material, reduces cost; W shape filter core rigidity is big, can bear strong current and impact;
3, compacter than the traditional filtering apparatus structure of identical through-flow multiplying power, reduction takes up room, and is convenient to design arrangement;
4, the rotation feculence box of band wire brush is adopted in blowdown, can by force the foreign material attached to screen surface be brushed, and enters feculence box, and scrubbing is thoroughly clean, and the foreign material of feculence box directly enter blow-off pipe and concentrate blowdown, conserve water resource.
5, because adopted that web-roll core is fixed, the version of blowdown box rotation, thereby dynamic and static gaps is little, sealing is reliable easily, foreign material can be through the dynamic and static gaps clean water area of bleeding, reliability increases.
The invention will be further described below in conjunction with accompanying drawing for description of drawings.
Fig. 1 is the front view of W shape filter,
Fig. 2 is the enlarged drawing of M portion among Fig. 1,
Fig. 3 is the right view of W shape filter,
Fig. 4 is the axial cutaway view of W shape filter core,
Fig. 5 is the enlarged drawing of A portion among Fig. 4.
Among the figure: 1-cylindrical shell, 101-water inlet, 102-delivery port, 103-sewage draining exit, 104-blow-off pipe, 2-filter core, 201-skeleton, 202-wire side, 3-blowdown mechanism, 301-feculence box, 302-Dirt-cleaning brush, 4-power drive mechanism, 5-main shaft.
The specific embodiment is as shown in Figure 1: a kind of W shape filter, and by cylindrical shell 1, cylindrical shell 1 is provided with water inlet 101, delivery port 102, sewage draining exit 103, the filter core 2 that is positioned at cylindrical shell, blowdown mechanism 3, main shaft 5 and forms with power drive mechanism 4; Filter core 2 overall fixed are on cylindrical shell 1; Referring to Fig. 2 to Fig. 5: the axial section of filter core 2 is W shape, and this W shape filter core 2 is made up of skeleton 201 and the wire side 202 that is attached on the skeleton 201; The two ends of W shape filter core 2 are on cylindrical shell 1, and filter core 2 centers are equipped with main shaft 5, and transmission mechanism 4 links to each other with main shaft 5, fixed installation one cover blowdown mechanism 3 on the main shaft 5, and blowdown mechanism 3 is made up of feculence box 301 and the Dirt-cleaning brush 302 that is fixed on the feculence box 301; The free end of Dirt-cleaning brush 302 is close to the inner surface of the wire side 202 of W shape filter core 2; Feculence box 301 is connected with blow-off pipe 104.
As the part of improving of the present invention, the speed change commutation case that is positioned at the power drive mechanism 4 of cylindrical shell 1 adopts all-sealed structure, with the erosion that prevents that water from causing drive disk assembly, to guarantee service life.
Cylindrical shell is preferably taked split type, modular structure, and being about to cylindrical shell, to make several recombinants respectively be one, and like this, Maintenance and Repair are convenient.
