Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
nullSuch as Fig. 1、In embodiment shown in Fig. 2，A kind of twin screw conveying equipment possessing cold guarantor's function，Including outer pump case 1、Material conveyor chamber 21、Charging aperture、Discharging opening、Two conveying screw rods 22 being located in material conveyor chamber，Charging aperture all connects material conveyor chamber with discharging opening，Interior pump case 2 it is provided with in described outer pump case，Material conveyor chamber is in interior pump case，Cooling temperature control chamber 11 is formed between outer pump case and interior pump case，Outer pump case is provided with main feed tube 3、Main drain pipe 4，One cooling pump 31 is connected by main feed tube with cooling temperature control chamber，Main drain pipe connects with cooling temperature control chamber，Main feed tube is provided with main feed liquor on-off valve 32，Main feed tube is provided with feed liquor arm 5，The main feed tube of feed liquor arm inlet communication，Outer pump case is provided with some heat conduction columns 12，Heat conduction column sidewall is affixed with outer pump case sidewall，Heat conduction column lower end is provided with the cylinder feed tube 121 that connect internal with heat conduction column，Feed liquor branch outlet connects all cylinder feed tubes，Heat conduction column upper end is provided with the cylinder drain pipe 122 that connect internal with heat conduction column，Feed liquor arm is provided with a feed liquor on-off valve 51,Also include recovery tube 13，Recovery tube is provided with recovery liquid outlet、Some recovery inlets，Reclaim inlet and cylinder drain pipe one_to_one corresponding，Reclaim inlet to connect with corresponding cylinder drain pipe，Reclaim liquid outlet and connect a shower nozzle 14，At shower nozzle outside directly over pump case，The injection direction of shower nozzle is downward,Shower nozzle is provided with the shower nozzle on-off valve for switching shower nozzle on off operating mode，Recovery tube is provided with the drain collecting pipe 15 connected with recovery tube，Drain collecting pipe is provided with the collection on-off valve 151 for switching drain collecting pipe on off operating mode.Utilize the space between outer pump case and interior pump case to form cooling temperature control chamber, and the material conveyor chamber cooling down temperature control chamber and Quimby pump itself separates.Cooling pump cooling water (or coolant) can send into cooling temperature control chamber from water source through main feed tube, then discharges through main drain pipe, and cooling water takes away a part of heat in the process, thus can effectively temperature control and protection, prevent temperature too high.And as variousization machine equipment, cooling temperature control intracavity is likely to there will be the blocking caused because of the factor such as fouling, corrosion.And the existence of each heat conduction column; can continue Quimby pump is carried out temperature control protection when blocking, it is to avoid in production process, (when Quimby pump carries out material conveying, on production line, miscellaneous equipment is also being operated simultaneously in shutdown comprehensively; once shut down; need the most temporarily to stop production, thus affect rhythm of production and efficiency, and continue to Quimby pump work; until a production procedure terminates; as carried a batch materials, keep in repair the most again, then can smooth and easy and stable with effective guarantee production process).When blocking occurs in cooling temperature control chamber; a feed liquor on-off valve can be opened; cooling water reaches heat conduction column from feed liquor arm through each cylinder feed tube, and (heat conduction column can be made up of various typical thermal-conductive materials; such as copper, cast iron and alloy etc.); and there is heat exchange with Quimby pump inside; take away a part of heat, thus can continue to cool down temperature control and protected effect.The cooling water entering heat conduction column then can be discharged from cylinder drain pipe.And the cooling water discharged from cylinder drain pipe can be carried out unifying to reclaim and send into shower nozzle (now collect on-off valve closedown, shower nozzle on-off valve is opened) by recovery tube; cooling water is sprayed onto on outer pump case by shower nozzle; carry out external auxiliary cooling protection (after cooling water absorbs heat in heat conduction column; temperature is still far below interior pump case temperature; can also continue to heat absorption); thus further with cooling water, more energy-conserving and environment-protective, cooling temperature control effect is the most more preferably；If need not shower nozzle supplement heat rejecter, then the cooling water discharged from cylinder drain pipe can be carried out unifying to reclaim and send into drain collecting pipe (now collection on-off valve is opened, shower nozzle on-off valve is closed) by recovery tube, and cooling water is transported to retracting device or discharges by drain collecting pipe again.
Described feed liquor arm is provided with the protection unblank valve for switching feed liquor arm on off operating mode, protection unblank valve includes the valve seat 61 being located on feed liquor arm, the spool coordinated with valve seat slipper seal, the valve spring 62 being located in valve seat, spool is a rectangle partition panel 63, rectangle partition panel has two plate faces, two long sidewalls, two short sidewalls, two plate faces of rectangle partition panel, two long sidewalls all coordinate with slipper seal between spool inwall, rectangle partition panel is provided with the unblank hole 631 running through two plate faces of rectangle partition panel, valve seat has inner end plate 611, outer stomidium, one short sidewall of rectangle partition panel is just to inner end plate, another short sidewall of rectangle partition panel just externally stomidium, outer stomidium is connected with main feed tube by unblank bypass duct 64；
In valve seat: the space between outer stomidium and rectangle partition panel is unblank chamber 65, valve spring is between inner end plate and rectangle partition panel, and valve spring one end connects inner end plate, and the valve spring other end connects rectangle partition panel, when valve spring is in naturalness, standby feed liquor arm is cut off by rectangle partition panel.The communicating position of described unblank bypass duct and main feed tube is between cooling temperature control chamber and main feed liquor on-off valve, and unblank bypass duct is provided with unblank branch road on-off valve 641.
This programme unblank can protect road (feed liquor arm) automatically; before work; first unblank branch road on-off valve and a feed liquor on-off valve are opened (unblank branch road on-off valve can be normally open with a feed liquor on-off valve); when normally working; cooling water still walks to cool down temperature control chamber; and it is limited to cool down the thrust that current are applied on spool (rectangle partition panel); it is not enough to overcome the active force of valve spring that towards inner end plate, rectangle partition panel is promoted more distance; now unblank hole cannot connect with feed liquor arm, and feed liquor arm is in off-state.And when blocking occurs in cooling temperature control chamber; unblank intracavity hydraulic pressure increases; as a example by Fig. 2; now current can press rectangle partition panel and move right; unblank hole connects with feed liquor arm; cooling water can enter each heat conduction column through feed liquor arm, thus carries out cooling down temperature control and protection, it is achieved that the effect of " protection road starts automatically ".
Being provided with the limit base 66 for limiting spool displacement in described valve seat, limit base is fixed with valve seat, and limit base is between inner end plate and rectangle partition panel；During rectangle partition panel contact limit base, unblank hole is coaxial with feed liquor arm.During in order to prevent hydraulic pressure excessive, spool rectangle partition panel displacement is excessive, is provided with limit base, thus can ensure when hydraulic pressure is bigger, and spool still can be in rational position (will not excessively move inward), keeps good cooling water handling capacity.
