A kind of suction filter
Technical field
The present invention relates to industrial sewage and the clean water treatment fields such as mine, cement, metallurgy, papermaking, the suction strainer valve member when particularly relating to sewage disposal.
Background technology
The normal wet method of putting out that adopts of coking plant mainly is that water pump sucks from the pond, water is through equipment such as elevated tanks, be sprayed to from the quenching tower top at last and connect burnt case, because water pump suction inlet strainer valve is in basin bottom for a long time, and have breeze etc. dirty the thing etch, screen pack also easily occur to stop up and the aperture diminishes even fully by shutoff, affect water yield, even normally quenching.So need often it to be cleared up, therefore continuously strainer valve cleared up and had a strong impact on the operation of coming out of the stove normally.
Simultaneously, because this strainer valve of cleaning need to all be drained the water in the pond, then the operating personnel enters basin bottom and carries out prune job, cause is limited by the unfavorable factors such as narrow space, the bottom eyelet can't touch, so clearance time is long, whole operation needs four to five hours, and on-the-spot many factors on the safety work impact is cleared up not only time-consuming but also take a lot of work.
Summary of the invention
The purpose of this invention is to provide a kind of the needs drains the water pool inner water, the suction filter that only just can directly clear up or change strainer valve under than the low water level state.
For this reason, the invention provides a kind of suction filter, comprise bend pipe, be installed on the strainer valve of bend pipe top, also comprise guide post, described guide post is positioned at the strainer valve axis, and its bottom is fixed with elbow internal wall, and returning apparatus lifts the hole on the upper surface of described strainer valve.At first increased this member of bend pipe, thereby changed vertical device strainer valve into by original horizontal device strainer valve, two end faces of strainer valve go to upper and lower distribution.Also set up simultaneously this member of guide post, the inwall of guide post and bend pipe is fixed, and passes from the axis of strainer valve, so that strainer valve can move up and down along guide post.The main outer power of the tractive force that strainer valve moves upward is to lifting the effect realization in hole, and it moves downward main gravity by strainer valve self and realizes.
In order to guarantee the stability of strainer valve and bend pipe, also include gland so the present invention further discloses, described gland is installed on the guide post outside, and locks by locking nut.That is to say that gland is positioned at the guide post outside, with guide post be that the gap arranges, and its upper end is by the locking of locking nut and guide post, thereby guaranteed closely to engage between strainer valve below it and the bend pipe, simultaneously since this pretightning force also so that filter the Operating stability of valve raising.
Certainly, in the middle of actual production process, for for convenience detach, the invention discloses described gland and formed by two or more short glands.
Simultaneously, when promoting for the ease of strainer valve, the combination of various elevators and strainer valve, the present invention further discloses the described hole that lifts is coaxial annulus, circular planes is vertical with the strainer valve end face.
In order further to improve the stability of guide post, the inventor discloses this member of connecting rod, and when not having the gland member, described connecting rod one end and guide post are fixed, and the other end and body of wall or other resistates are fixed; After gland was set up in the guide post outside, described connecting rod one end and gland were fixed, and the other end and body of wall or other resistates are fixed.Thereby on horizontal level, guaranteed the stability of guide post.
In sum, adopt technical scheme disclosed in this invention after, can directly strainer valve be left the water, and then carry out prune job.Thereby realized that the activity duration is short, cleaning is thorough, efficient is high, operational security is good, the technique effect little to the coke oven Influence of production.

The specific embodiment
Embodiment 1
As shown in Figure 1, the suction filter comprises that bend pipe 1, strainer valve 2, a left side lift hole 301, the right side lifts hole 302, bottom gland 401, top gland 402, lower locking nut 501, upper locking nut 502, guide post 601, front rod 701 and rear connecting rod 702.Guide post 6 is fixed installation with bend pipe 1; Guide post 6 is matched in clearance with strainer valve 2, bottom gland 401, top gland 402; Lower locking nut 501, upper locking nut 502 are thread connection with guide post, by the pretension of this screw thread, can make gland, suction valve and bend pipe relative fixing; Top gland 402 is thread connection with fixed bar 701,702.
During use, 90 degree bend pipes 1 are installed in water pump suction inlet pipeline top, and the top of this bend pipe 1 is equipped with long guide post 6, will absorb water strainer valve 2 devices on guide post 6, and in the upper surface of strainer valve 2 coaxial annulus is installed, namely a left side lifts hole 301, the right side lifts hole 302; In the time of need to lifting, outward winding locking nut 501 and 502, and utilize winding drum or chain block or on-the-spot coke breeze grab bucket elevator etc. to lift apparatus, by a left side lift hole 301, the right side lifts hole 302, strainer valve 2 is drawn to the top by the bottom of guide post 6, and further strainer valve 2 is taken out, and finish follow-up cleaning.
After finishing cleaning treatment, strainer valve 2 is slided into the bottom by guide post 6 tops, the guide post 6 of then bottom gland 401 and top gland 402 sequentially being packed into, and adopt locking nut 501 and 502 lockings on the top of top gland 502.Nut 501 and 502 lockings because top is locked, so strainer valve 2 is closely linked with bend pipe 1, strainer valve 2 is subject to the pretightning force of locking nut 501 and 502, has kept the stability of position, thereby has guaranteed that whole device is in the stability of vertical direction.
For preventing guide post 6 unstabilitys, on the top of top gland 402 connecting rod 701 and 702 are installed, this connecting rod other end and body of wall are fixed, and play guide post stabilization in the horizontal direction.
Above-mentioned gland and locking nut, connecting rod play respectively the stabilization of vertical direction and horizontal direction to device, thereby can select one according to actual conditions and select or select simultaneously.
