Abstract
The invention relates to a double-cylinder dirt separator. The aim of the invention is to solve the problem that the prior dirt separator fails to achieve a required dire separation effect during use, is susceptible to blockage caused by large-sized dirt and flotage and has a short maintenance period, uneasy maintenance and influence on heat supply effect when a larger amount of impurities exist in a heat supply system. The lower end of a coaxial sleeve pipe of the dirt separator is communicated with the upper end of an outer cylinder, the upper end of the coaxial sleeve pipe is communicated with the lower end of an inlet sleeve pipe, a water outlet pipe is arranged in the inlet sleeve pipe and the coaxial sleeve pipe, an inner cylinder is arranged on the upper part of the outer cylinder, the upper end of the water outlet pipe is fixedly connected with an outlet flange, and the lower end of the water outlet pipe is communicated with the upper end of the inner cylinder. The dirt separator can remove more than 90 percent of molding sand with a grain diameter of 1 millimeter under a condition of an inlet flow of less than 3m/s, and can remove more than 80 percent of molding sand with a grain diameter of 0.5 millimeter under a condition of an inlet flow of less than 2.0m/s.
Description
Technical field
The present invention relates to a kind of dirt separator.
Background technology
Because employed cast-iron radiator inner chamber scab in the existing heating system constantly comes off in the process of using, because the particle diameter of molding sand is very little, employed dirt separator is unsatisfactory to its removal effect in the existing heating system.In order to address the above problem, China Patent No. be ZL02210839.4, Granted publication number be that the utility model patent that February 12 in 2003, day, were called " centrifugal high effective dirt separator " discloses a kind of dirt separator for CN2535663Y, Granted publication day, this dirt separator does not in use reach the scrubbing effect described in the patent specification, for bigger dirt and floating thing, stop up easily.In heating system impurity more in, the maintenance period of dirt separator is shorter, not easy care and influence heating effect.
Summary of the invention
The objective of the invention is in use not reach due scrubbing effect,, stop up easily for bigger dirt and floating thing for solving existing dirt separator.In heating system impurity more in, the maintenance period of dirt separator is shorter, easy care and influence the problem of heating effect does not provide a kind of double-drum type dirt remover.The present invention comprises outlet(discharge) flange, inlet cannula, the inlet short tube, urceolus, inner core, the hand hole flange, sewage draining exit, the rectification orifice plate, suction flange, coaxial sleeve and outlet pipe, sewage draining exit is connected outer tube bottom, the hand hole flange is connected on the sidewall of urceolus, the lower end of coaxial sleeve is connected with the upper end of urceolus, the upper end of coaxial sleeve is connected with the lower end of inlet cannula, suction flange is fixedly connected on the inlet short tube of inlet cannula front end, outlet pipe is arranged in inlet cannula and the coaxial sleeve, outlet pipe is fixedlyed connected with inlet cannula, inner core is arranged on the top in the urceolus, the bottom of inner core is open, the upper end of outlet pipe is fixedly connected with outlet(discharge) flange, the lower end of outlet pipe is connected with the upper end of inner core, the rectification orifice plate is fixed on the top in the inner core, outlet pipe is an aquaporin with the coaxial setting of coaxial sleeve, the space between outlet pipe and the coaxial sleeve.
In design process of the present invention, in order to obtain interior flow field preferably, with the basic structure design of dirt separator is axisymmetric version, and has proposed the version of the inside and outside bitubular of novel dirt separator main body, and go out on enterprising, the import and export scheme of coaxial sleeve.In order to reduce dirt separator internal flow flow velocity effectively, make its interior flow field more even, installed the rectification orifice plate additional on inner core top.Owing to adopted the version of the inside and outside bitubular, increased dirt separator inner fluid flow process, reduced the volume of dirt separator effectively.The import and export of dirt separator are designed to the version that goes out on enterprising, in the process of scrubbing, have made full use of the inertia and the gravity of solid particle.At importing and exporting coaxial problem, designed inlet cannula.The present invention adopts low speed sedimentation principle, and the heating system backwater enters dirt separator through inlet flange and enters behind aquaporin in the dirt separator urceolus, and the solid particle divided flow settling is to the bottom of dirt separator in urceolus.Upwards by inner core, after shunting was slowed down through the rectification orifice plate, solid particle is sedimentation once more, arrives outlet sleeve at last, flows out dirt separator through outlet(discharge) flange again through the fluid after the sedimentation.Thereby realize efficient scrubbing.
Invention effect:, obtain the removal efficient of this dirt separator to solid particle through theory and sunykatuib analysis.Be lower than under the situation of 3m/s at the inlet flow velocity, its removal efficient to the molding sand of 1mm particle diameter has reached more than 90%; Be lower than under the situation of 2.0m/s at the inlet flow velocity, for the removal efficient of the molding sand of 0.5mm particle diameter more than 80%.
