Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Key of the present invention is the unpowered circulation realizing glueballs.
The present invention as shown in drawings is a kind of unpowered condenser glueballs automatic on-line cleaning device, in order to reduce the impact of on-line cleaning device on cooling water circulation, bypass pipe 4 is set, the cooling water upstream end of described bypass pipe 4 and cooling water water side are connected with the cooling water inlet pipe 2 being connected condenser 1 respectively, are provided with stop valve 5, de Laval noz(zle) (i.e. Laval nozzle) 6 and the first check-valves 7 from bypass pipe 4 cooling water upstream end to cooling water water side successively.A small amount of cooling water enters bypass pipe, and cooling water inlet is controlled by the aperture of stop valve 5.De Laval noz(zle) (i.e. Laval nozzle) 6 is commercially available, de Laval noz(zle) is made up of two conical pipes, the collapsible tube of de Laval noz(zle) is cooling water water inlet end, described de Laval noz(zle) convergent divergent channel is cooling water water side, the throat of de Laval noz(zle) is connected with the outlet of service pipeline 8, described service pipeline is provided with motor-driven valve 9, is controlled the transmitting of bead by motor-driven valve 9, described service conduit entrance exports with storage spherical tank 10 and is connected.Storage spherical tank has visor 11.When on-line cleaning device is served a ball, motor-driven valve 9 is opened, and be communicated with service pipeline and de Laval noz(zle), in by-pass line, current flow through de Laval noz(zle), flow velocity increases suddenly, pressure reduces, and nozzle throat pressure is lower, and the glueballs thus in storage spherical tank sucks in bypass pipe by service pipeline, first check-valves 7 is set in bypass pipe, prevent current from flowing backwards, ensure that glueballs enters cooling water inlet pipe smoothly, complete the transmitting of glueballs.Service terminates, and motor-driven valve cuts out automatically.When on-line cleaning does not work, motor-driven valve cuts out, and glueballs is in storage spherical tank.The transmitting of glueballs is controlled by motor-driven valve, the unlatching duration of motor-driven valve 9 can be set according to different cooling water qualities, handpiece Water Chilling Units running status, glueballs quantity and open frequency realizes controlling cleaning frequency, more handpiece Water Chilling Units situations can be adapted to like this, reach better automatic on-line cleaning performance.Cooling water only has and enters in bypass pipe on a small quantity, does not substantially affect the operation of handpiece Water Chilling Units, comes unlatching or the closedown of matching purge device without the need to frequent adjustable cut-off valve 5.Be connected with the arrival end of ball collecting device 12 at the port of export in the cooling water outlet pipe road 3 connecting condenser 1, the outlet of described ball collecting device 12 is connected with the import of storage spherical tank 10 with the receipts bulb road 13 be flexible coupling by being equipped with the second check-valves.
Described ball collecting device 12 can adopt existing structure, ball collecting device 12 structure in the present embodiment comprises cylindrical shell 16, in described cylindrical shell 16, funnel-form filter screen 15 is installed, wherein the big opening end of filter screen 15 is connected by the port of export of flange with cooling water outlet pipe road 3, and the osculum end of filter screen 15 is connected with the arrival end receiving bulb road by connecting pipe 17.Ball collecting device sieve meshes diameter is less than glueballs diameter.
Glueballs enters condenser 1 along with cooling water, and after completing the cleaning to condenser, reclaimed by the ball collecting device 12 connected on the cooling water outlet pipe road 3 of condenser 1, the glueballs tackled enters in storage spherical tank 10 along receipts bulb road 13, completes circulation.Ball collecting device sieve meshes diameter is less than glueballs diameter, the mesh area of preferred filter screen 15 can reach 1.5 times of conduit cross-sectional area, can while interception glueballs, do not increase flow resistance as far as possible, ensure that current are connected with receipts bulb road normal through, tube connector 17, guarantee glueballs can reclaim smoothly, ball collecting device is connected with cooling water outlet pipe road by flange 14, installs simple and convenient.Storage spherical tank has visor 11, the situation of glueballs can be observed by visor at any time, determine that glueballs is the need of replacing.Connect on the receipts bulb road storing up spherical tank and pipeline of serving a ball and all there is valve, when need change glueballs, the valve at two ends can be closed, carry out glueballs replacing by visor, simple and convenient.
