Description
Technical field
The utility model relates to a kind of low voltage difference transmission valve, especially relates to a kind of low voltage difference transmission valve being suitable for that the vacuum tunnel formula baking box of lithium battery or lithium battery pole slice uses.
Background technology
At present, in new energy materials manufacturing process, also need if desired to toast new energy materials, to remove moisture content, such as, the manufacture of electrodes of lithium-ion batteries or lithium ion battery, just needs electrodes of lithium-ion batteries or lithium ion battery to carry out degree of depth oven dry.What modal drying plant adopted is Inner eycle list casing baking box, it first loads in vacuum bakeout case by the lithium battery be baked or battery electrode, again vacuum bakeout case is sealed, at ambient pressure, first the material that is baked in casing is heated, heat up, after the temperature inside the box reaches requirement, when being incubated, removing moisture will be vacuumized in casing, after the water content of battery pole piece reaches requirement, again the electrode of lithium cell be baked in casing or battery are cooled, nature can be selected to cool or force cooling, the temperature of electrode of lithium cell or the battery core be baked is dropped to a certain degree, the electrode of lithium cell be baked or battery are taken out sealing preserve, water content due to battery pole piece needs to reach very high requirement, and therefore, in whole process, the sealing of inner loop list casing baking box has strict requirement, crowd knows, in the manufacture process of electrodes of lithium-ion batteries or lithium ion battery, the operations such as the electrode slice coating before baking operation or the manufacture of battery are all the forms of continuous print streamline, and when will enter Inner eycle list casing baking box, thing to be dried is now just needed first to accumulate a certain amount of, put into described Inner eycle list casing baking box again to heat, heat up, the operation such as to vacuumize, although this kind of Inner eycle list casing baking box sealing is better, but this single casing baking box just makes baking operation cannot be streamline form with operations such as coatings before, and at every turn all need thing to be dried to insert in Inner eycle list casing baking box or in Inner eycle list casing baking box and take out, so just cause operation numerous and diverse, reduce production efficiency.
In order to solve the problem, enhance productivity, pertinent art investigated a kind of tunnel type vacuum oven, as shown in Figure 2, Fig. 2 is two adjacent functional compartment body partial schematic diagrams of existing tunnel formula baking line, and whole piece tunnel type baking line is made up of the structure that more piece is such.The general structure of this tunnel type baking box is, comprise adjacent two working box 100, 200, working box 100 between described, 200 are provided with transmission valve, described transmission valve comprises the enclosed hood 300 be tightly connected with described working box, be located at the reciprocating drive mechanism 400 in described enclosed hood 300, and for doing for described reciprocating drive mechanism 400 the first guide be arranged in parallel spaced a predetermined distance and the second guide (not shown) that pump, described reciprocating drive mechanism 400 comprises reciprocating drive unit 410, the nut-screw rod structure 412 or gear & rack structure that motor 411 drives is generally with described reciprocating drive unit 410() the reciprocal driving gate 460 that is connected, and the hermatic door open-and-close mechanism 420 to be connected with reciprocal driving gate 460, described hermatic door open-and-close mechanism 420 is connected with the first hermatic door 430 and the second hermatic door 440, in described enclosed hood 300, be provided with for described reciprocal driving gate 400 move around dodge space 450, when two described hermatic doors 430,440 draw in, described reciprocal driving gate 400 moves to described predetermined when dodging in space 450, is communicated with between two described working box 100,200, on the contrary, the case mouth 110,210 of working box 100,200 is spaced by described hermatic door 430,440 and corresponding sealing ring 431,441 thereof by two described working box 100,200, in real work, when the pressure difference of adjacent two described working box is larger, the hermatic door of side working box less for pressure can tightly be pressed on the less side working box of pressure by the pressure in the side working box that pressure is larger, uses two working box to cut off, but when the pressure in two described working box is equal or pressure difference is less, when absolute value as the difference of the pressure P2 in the pressure P1 in the first working box 100 and the second working box 200 is less than 10,000 Pa, due between hermatic door 430, 440 and two working box 100, sealing ring 460 between 200, the bounce effect of 470, want to make two working box 100, by hermatic door 430 between 200, 440 separate completely, just need reciprocating drive unit 410 to hermatic door 430, 440 impose enough large power, and keep this power, just can make two working box 100, 200 cut off completely.Existing reciprocating drive unit 410 generally adopts motor by nut-screw rod structure or the reciprocal driving gate 460 of gear-rack drive, realize hermatic door 430,440 folding, but, existing working box will complete a procedure all needs the regular hour, if kept the sealing of hermatic door 430,440 for a long time by motor-driven mode, be easy to the life-span (burn-down of electric motor) shortening motor.In order to head it off, people devise and replace motor to drive reciprocal driving gate 400 with cylinder, but in the unstability due to air pressure, affect the sealing effectiveness of hermatic door 430,440, if adopt enough large atmospheric pressure to push down hermatic door open-and-close mechanism 420, although can sealing effectiveness be improved, for hermatic door open-and-close mechanism 420 designing requirement and with material require also very high, increase manufacturing cost; People devise again and replace motor to drive reciprocating drive mechanism 400 with oil cylinder, although have good sealing effectiveness, and, because oil cylinder needs a whole set of oil hydraulic system next supporting, cost is very high.How namely can adopt lower-cost motor drive mode, and motor service life can be extended, and neither be very high to the designing requirement of hermatic door open-and-close mechanism 420, can improve again the sealing effectiveness of hermatic door 430,440 well, be industry technical staff problem demanding prompt solution.
