Abstract
The utility model discloses a pollution discharging structure of self-washing filter capable of absorbing a pollution discharging impact force and noise. The pollution discharging structure of self-washing filter comprises a pollution discharging pipe front section, a pollution discharging pipe tail section, a self-washing filter and a pollution discharging valve, wherein the pollution discharging valve is arranged at a pollution discharging hole of the self-washing filter, the pollution discharging pipe front section, a pollution discharging flexible pipe and the pollution discharging pipe tail section are sequentially arranged between the pollution discharging valve and a pollution discharging groove, the vertical distance between the pollution discharging valve and the pollution discharging groove is 1.5-3 m. According to the pollution discharging structure, a flexible pipe structure is adopted, that is, the middle section of an original pollution discharging pipe is changed into the flexible pipe; because the flexible pipe has better flexibility and elasticity, the flexible pipe is capable of absorbing vibration and also capable of absorbing noise generated by vibration of a unit. After the flexible pipe structure is adopted, the fatigue damage resisting capability of a system is improved, the service life of the pollution discharging pipe is prolonged; the noise is lowered. The pollution discharging structure is simple in structure, easy to make, convenient and simple to operate, safe to use, and capable of effectively absorbing the pollution discharging impact force and noise of the self-washing filter.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, further belongs to water circulation use equipment technical field, is specifically related to a kind of simple in structure, make easily, easy and simple to handle, use safety, can effectively absorb blowdown impulsive force and noise from flush filter pollution discharge structure.
Background technology
China is world Chan Gang big country, and steel-making has realized continuous casting operation, and in continuous casting operation, conticaster need to consume a large amount of water, and also higher to water quality requirement, especially cooling water, equipment clean circulating water etc.For saving water resource, water all recycles.Owing to having aborning dirt, enter water system, so must filter cooling water in water cycle process.Circular-arc type continuous casting machine is all generally to adopt flushing certainly (backwash) filter of Ford Ma Te to filter.Current is all to adopt carbon steel seamless steel pipe from flush filter blow-off pipe, and 15 meters of blow-off pipe length are with interior caliber requirement >=50mm, 15 meters of above requirement >=64mm.In current use, because reasons such as water quality inferiority, conticaster operating rate height, so filter is also very high from the frequency of rinsing, after rinsing, sewage flow to dirt discharge groove through blow-off pipe, then enters turbid circulating water system.Cleaning, during blowdown, the pressure of sewer often reaches 30bar, the time that each blowdown is rinsed is 12s-15s etc., so pressure and impulsive force that when rinsing, blow-off pipe is subject to are very large, make its generation vibrate and make a noise, blow-off line vibration is very serious, to causing very large potential safety hazard from equipment such as flush filters.Due to blow-off pipe vibration, not only shortened the service life of blow-off pipe, blowoff valve, increase the use amount of spare part, and affected the equipment of blow-off pipe periphery; Meanwhile, noise is large and frequent, serious harm operating personnel's physical and mental health, and then affect carrying out smoothly of production operation, affect the economic benefit of enterprise.For this reason, research and develop a kind of simple in structurely, make easily, easy and simple to handle, use safety, what can effectively absorb blowdown impulsive force and noise is the key addressing this problem from flush filter pollution discharge structure.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and makes easily, easy and simple to handle, uses safety, can effectively absorb blowdown impulsive force and noise from flush filter pollution discharge structure.
The purpose of this utility model is to realize like this, comprise blow-off pipe leading portion, blow-off pipe rear, from flush filter, blowoff valve, the described sewage draining exit place from flush filter arranges blowoff valve, between described blowoff valve and dirt discharge groove, set gradually blow-off pipe leading portion, blowdown flexible pipe, blow-off pipe rear, described blowoff valve and the vertical range between dirt discharge groove are 1.5 ~ 3m.
The utility model adopts hose construction, and the stage casing that is about to raw sewage disposal pipe changes flexible pipe into; Because flexible pipe has flexible, elasticity preferably, can absorb vibration, can absorb the noise that unit vibration produces, and absorb the noise that in piping, fluid pulsation produces simultaneously.Adopt after hose construction, improved the ability that system antifatigue is destroyed, extended the service life of blow-off pipe, reduced the use amount of blow-off pipe; Reduce noise simultaneously, improved operating personnel's working environment, protected equipment, improved the economic benefit of enterprise.The utility model is simple in structure, makes easily, easy and simple to handle, uses safety, can effectively absorb blowdown impulsive force and noise from flush filter.
