Недостатком данной конструкции гидроциклона вл етс то, что вследствие отсутстви автоматического регулировани ширины кольцевого канала при осветлении в аппарате жидкости , имеющей механические примеси с раз15 мерами частиц, превышающими ширину кольцевого канала, последний частично забиваетс , в результате чего ухудшаетс гидродинамика потока в аппар.ате, увеличиваетс сопротивление и давление в корпусе гидроциклона, происхо20 дит вьшос сгущенного продукта в сливной патрубок.The disadvantage of this hydrocyclone design is that, due to the absence of automatic adjustment of the width of the annular channel when clarifying a fluid in the apparatus, having mechanical impurities with particle sizes exceeding the width of the annular channel, the latter partially clogs up, as a result of which the hydrodynamics of the flow in the arrester deteriorates The resistance and pressure in the hydrocyclone case increases, and the condensed product exits into the drain pipe.

Claims

The purpose of the invention is to improve the hydrodynamics of the flow, in the apparatus, and to reduce the output of the condensed product into the drain pipe by automatically adjusting the width of the annular channel. The goal is achieved by the fact that a hydrocyclone containing a cylindrical housing open at the bottom with a tangential supply nozzle, coaxially mounted in the housing a hollow conical insert with openings in the upper part located a large base at a distance from the lower part of the housing, an annular channel for removal of the condensed product and the outlet pipe of the clarified liquid, provided with a glass with a spring and a stem placed inside it. The drawing shows a hydrocyclone general view. The hydrocyclone consists of a cylindrical tank I with a tangential supply nozzle 2, a hollow conical insert 3 with openings 4 in its upper part, a drain pipe 5, a canal 6, a spring 7, a rod 8, a clamping ring 9 and a cover 10. Insert 3 forms with the housing 1 an annular channel 11 for the withdrawal of the condensed product. Hydrocyclone works as follows. The liquid to be cleaned tangentially along the supply nozzle 2 is fed into the housing 1 and receives a rotational movement. Under the action of centrifugal forces mechanical impurities are thrown to the walls of the housing and discharged through the annular channel P. The clarified liquid enters through the opening 4 into the cavity of the conical insert 3 and is discharged through the drain nipple 5. If the annular channel 11 is behind; beats large particles of mechanical impurities, then. The pressure in the case of the hydrocyclone increases and under the action of the vertical parting force of the floor pressure, the conical insert 3, compressing the spring 7, descends, the width of the annular channel increases and the contaminated material jumps out. The pressure inside the apparatus is restored and the insert 3 is returned to its original position by the action of the spring 7. The rod 8 is screwed into the cover 10 and serves to adjust the initial compression of the spring. When cleaning suspensions containing polydisperse fractions of particles, in the hydrocyclone of a known construction, the annular channel clogs with particles of a large fraction, which ultimately reduces the efficiency of the apparatus, whereas in the hydrocyclone of the proposed construction such an effect is not observed. DETAILED DESCRIPTION OF THE INVENTION Gndrocyclone for purification of natural and waste waters from mechanical impurities, comprising a cylindrical housing open at the bottom with a tangential supply nozzle, coaxially mounted in the housing a hollow conical insert with openings in the upper part located a large base at a distance from the lower part of the body, an annular the channel for removal of the condensed product and the outlet of the clarified liquid, differing in 1 and in order to improve the hydrodynamics of the flow in the apparatus and reduce the height of the condensed gas THE PRODUCT in the spout by automatically adjusting the width of the annular channel, the hydrocyclone is provided with a cup placed inside the spring and the rod.
