Two sides of the partitioning plates are provided with the through holes, thus local flow static phenomenon on the rear sides of the partitioning plates can be effectively eliminated, thus the cooling efficiency of the vacuum cooling water tank is increased; and the vacuum cooling water tank has a simple structure, and is easy to process.
Description
Technical field
The utility model relate to a kind of plastic material in the extrusion molding process further to the finalize the design device of cooling of extruded parisons, but a kind of vacuum cooled water tank of mixed flow specifically.
Background technology
Just extruded plastic profile need cool off with water tank usually, and there is the typing hole that supplies section bar to pass through at this water tank two ends, and extrudes the fixing some shaped block of direction along section bar in the casing; Cooling fluid is injected by the section bar entrance point of casing; The section bar port of export of casing is provided with vavuum pump, and cooling fluid is taken away, takes the air in a part of casing simultaneously away; Make to form negative pressure state in the casing, and extrude at section bar and to form suction gradient on the direction.Owing to form certain negative pressure in the casing around the section bar cross section of hollow; And the hollow of section bar and external atmosphere pressure intercommunication; Thereby around the section bar cross section, form the shape that certain pressure differential guarantees section bar, the cooling medium around the section bar cools off section bar simultaneously.
The disclosed a kind of patent that comes to this of Chinese patent CN101053991B of the applicant's invention; Be provided with several dividing plates in the casing; Casing is extruded direction at section bar be separated into several chambers; Be provided with the hole that supplies section bar and cooling fluid to pass through in the middle of the dividing plate, each dividing plate is provided with shaped block in entrance point one side that section bar passes through, and the bottom of this shaped block and two side ends are connected with box sealing; Make the gap between shaped block and the dividing plate become the fluid course of front and back chamber, the height in the hole in the middle of the dividing plate is located at the liquid level below of next chamber; The passage that chamber communicated before and after the dividing plate upper end was provided with and makes.Cooling fluid is injected in the casing by the section bar arrival end; And next chamber is injected in the hole in the middle of shaped block top and dividing plate; Last chamber extruding direction adopts vavuum pump that cooling medium is taken away, also takes certain gas when cooling fluid is taken away away, makes to form negative pressure in the casing.Because the section bar that passes through is different, it does not highly wait, and the height of contour of the shaped block of its outer shape profile of decision moulding is also different, and the cooling fluid of chamber must climb over the shaped block upper end and flow into follow-up chamber, thereby realizes the automatic control of liquid level.
Yet there be stopping of dividing plate; Will be formed local static (the stagnant water phenomenon) of current by the dividing plate stop portions in the exit of water (flow) direction; Carry out continuously along with what section bar was extruded; The temperature of static place current will raise gradually, and has influence on the cooling effect of section bar afterwards, causes section bar production the defective of various abnormal conditions and section bar product to occur easily.
Summary of the invention
The purpose of the utility model is to the weak point that exists in the prior art, but a kind of vacuum cooled water tank of mixed flow is provided, and through increasing the mixed flow effect, can eliminate the local static phenomenon of membrane backside end current, improves cooling effect.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: the inherent section bar of casing is extruded direction and is separated into several chambers with dividing plate; Be provided with the hole that supplies section bar and cooling fluid to pass through in the middle of the dividing plate; Each dividing plate is provided with shaped block in entrance point one side that section bar passes through, and the bottom of this shaped block and two side ends are connected with box sealing, makes the gap between shaped block and the dividing plate become the fluid course of front and back chamber; The passage that chamber communicated before and after the dividing plate upper end was provided with and makes has the through hole that is communicated with forward and backward chamber at least in both sides, dividing plate bottom.
Take out in vacuum under the suction-operated of pipe, current flow to the local current of membrane backside through dividing plate lower end two side through hole and are prone to static position, to its disturbance, form mixed flow, make the static stagnant water of script begin to flow, thereby improve the cooling effectiveness of vacuum cooled water tank.
A preferred version of the utility model is: dividing plate is provided with downward fluid course in the cooling chamber both sides, and said through hole is communicated with fluid course with rear chamber.Current flow into rear chamber by the cooling chamber on the dividing plate through fluid course and through hole, and the direction in the time of can making flow flow to rear chamber is different, reaches the purpose of mixed flow.
In order to improve the mixed flow effect, the dividing plate both sides by down from have several are communicated with fluid course with rear chamber through hole.
Can know that by technique scheme the utility model forms mixed flow through offering through hole in the dividing plate both sides in the both sides of membrane backside; Can effectively eliminate in membrane backside and the static phenomenon of local current occur; Thereby improve the cooling effectiveness of vacuum cooled water tank, and simple in structure, be easy to processing.

The specific embodiment
Like Fig. 1, shown in Figure 2; Casing 1 inherent section bar is extruded direction and is separated into several chambers with dividing plate 2, is provided with the hole 22 that supplies section bar 4 and cooling fluid to pass through in the middle of the dividing plate 2, and each dividing plate 2 is provided with shaped block 3 in entrance point one side that section bar 4 passes through; The bottom of this shaped block 3 and two side ends are connected with box sealing; Gapped between shaped block 3 and the dividing plate, this gap forms the cooling chamber 21 that is communicated with forward and backward chamber, and cooling water flows to rear chamber 12 through cooling chamber 21 by hole 22 through shaped block 3 tops; The passage 26 that chamber communicated before and after dividing plate 2 upper ends were provided with and make; Cooling chamber 21 both sides have the fluid course 27 that communicates with cooling chamber 21 to dividing plate 2 in the liquid level lower part, both sides, dividing plate 2 rear end by down from have three through holes that communicate with fluid course 27 23,24,25.
This through hole 23,24,25 also can be set directly on the dividing plate 2 of cooling chamber 21 both sides forward and backward chamber 11,12 is communicated with.
When vacuum is taken out pipe 5 when vacuumizing; Cooling water flow to rear chamber 12 by front chamber 11 through cooling chamber 21, hole 22 under suction function; Form current 6 in the dividing plate both sides through fluid course 27 and through hole 23,24,25 simultaneously, as shown in Figure 3, these current 6 flow to the case sidewall direction; Form mixed flow, the static relatively phenomenon in part occurs thereby eliminate the both sides current.
