Abstract
The utility model relates to a guide device mechanism for an outside water-in and inside water-out downwards-spraying type rotary filtering net, which is characterized in that: the two ends of a connecting shaft are respectively connected with a shaft head through a shaft joint; the shaft head is connected with the connecting shaft by the shaft joint through a second connection bolt, so as to form a long transmission shaft; the shaft head is fixed between a lower support and an upper support by a third connection bolt, and is fixed on machine frame channel steel by a fourth connection bolt; and a chain wheel is sleeved on the shaft head. An oil-free lubricating bearing is sleeved at the inner side of the chain wheel; and the chain wheel is fixed on the shaft head by a pressing cover through a first connection bolt. The shaft head is supported by the lower support and the upper support; and a set screw penetrates through the upper support to fix the shaft head. The guide device ensures the flushing effect of equipment and has strong dirt cleaning capacity; trash cannot block off the filtering net, and the overflowing area is effectively applied; therefore, dirt remained on the filtering net cannot fall into a water-absorbing room, which provides favorable conditions for normal running of a circulating water pump and prolongs the service life of the equipment.
Description
Technical field
The utility model relates to the guider mechanism of the following spray rotary sieve of water outlet in a kind of outer water inlet, and specifically this utility model is used for rotary sieve, and this equipment is used for to the purification of water quality and the collection of dirt.
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 equipment has the filter efficiency height, dirty removal capacities is strong, equipment operates 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 control.
In prior art,, be adsorbed on the dirt on the web plate because web plate operates in vertical direction and washed by press water, be not easy to be washed away by press water, long-term accumulation causes filter screen to stop up, water level becomes big before and after the net, causes the screen frame distortion when serious, thereby influences the normal operation of water circulating pump.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides that a kind of clean-up capability is strong, the refuse cleaning guider of outside inflow inside outlet down-draft rotating type screen completely.
According to the technical scheme that the utility model provides, the guider of outside inflow inside outlet down-draft rotating type screen is made up of undersetting, upper bracket, holding screw, spindle nose, sprocket wheel, gland, first connecting bolt, shaft coupling, connecting axle, second connecting bolt, the 3rd connecting bolt, the 4th connecting bolt, Nonlubricated bearing and frame channel-section steel; Described connecting axle two ends connect spindle nose by shaft coupling respectively, shaft coupling connects to form a transmission long axis by second connecting bolt with spindle nose and connecting axle, spindle nose is fixed between undersetting and the upper bracket with the 3rd connecting bolt, and be fixed on the frame channel-section steel with the 4th connecting bolt, sprocket wheel is enclosed within on the spindle nose.
The inboard sheathed Nonlubricated bearing of described sprocket wheel, gland is fixed in sprocket wheel on the spindle nose by first connecting bolt.Described spindle nose is supported by undersetting and upper bracket, passes upper bracket by holding screw spindle nose is fixed.
Compared with the prior art the utility model has the following advantages:
The utility model can guarantee the developing result of equipment, and clean-up capability is strong, not network blocking of rubbish, area of passage is able to effective application, thereby the dirt that is dammed on filter screen can not fallen into suction chamber, for the normal operation of water circulating pump provides advantage, and can improve equipment service life.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise undersetting 1, upper bracket 2, holding screw 3, spindle nose 4, sprocket wheel 5, gland 6, first connecting bolt 7, shaft coupling 8, connecting axle 9, second connecting bolt 10, the 3rd connecting bolt 11, the 4th connecting bolt 12 and Nonlubricated bearing 13, frame channel-section steel 14.
Following spray rotary filter net mechanism capable described in the utility model, mainly be on the existing equipment basis, to add a cover jockey sprocket device, it mainly adopts at connecting axle 9 two ends, connect spindle nose 4 by shaft coupling 8 respectively, spindle nose 4 usefulness the 3rd connecting bolt 11 is fixed between undersetting 1 and the upper bracket 2, also is fixed on the frame channel-section steel 14 with the 4th connecting bolt 12, and sprocket wheel 5 is enclosed within on the spindle nose 4; Shaft coupling 8 is linked together spindle nose 4 and connecting axle 9 by second connecting bolt 10 and forms a transmission long axis; Described spindle nose 4 is supported by undersetting 1 and upper bracket 2 Houghs, links together by the 3rd connecting bolt 11, and after regulating the rigging position of transmission long axis, it is fixing with spindle nose 4 to pass upper bracket 2 by holding screw 3.Nonlubricated bearing 13 is enclosed within sprocket wheel 5 inboards, and gland 6 is fixed in sprocket wheel 5 on the spindle nose 4 by first connecting bolt 7.
Its web plate movement locus of the utility model changes the level run state into by original vertical operation, make screen pack running orbit when entering flush position that rubbish is housed change existing level into by original vertical direction, part rubbish relies on deadweight to fall, and along with powerful press water top-down flushing, rubbish is just poured tank, take away with water carriage system, clean-up capability strengthens, not network blocking of rubbish, area of passage is big, the dirt that dams on filter screen can not fallen into suction chamber, for the normal operation of water circulating pump provides advantage, has improved equipment service life.
