Description
Technical field
The present invention relates to a kind of be suitable for tunnel type baking oven can the transmission valve of rapid-maintenance.
Background technology
Many new high-tech materials all need the baking of very high request, if electrodes of lithium-ion batteries is after coating baking, also need deeper vacuum to toast, to reach the requirement of manufacturing battery.The degree of depth baking of present most of electrodes of lithium-ion batteries is also in single case baking stage, namely will be coated with in bake process, the battery pole piece of rolling puts into independent vacuum bakeout case, carries out heat temperature raising, vaccum dewatering and after several stage that cools, proceeds to later process; The disadvantage of this deep processing side is obvious, makes the production of whole battery pole piece exactly, from coating, elementary be baked to the degree of depth baking can not become continuous print active line, be not suitable for industrialization continuous operations.The applicant proposed in 2013 the patent application (see CN103398558A) that denomination of invention is " Full-automatic combination module new energy materials vacuum bakeout method and vacuum bakeout line ", wherein the technical scheme of vacuum bakeout line is: vacuum bakeout line comprises the function casing being with splice successively at least two functions of heat-insulation layer different, vacuum drying casing is at least included in described function casing, all functions casing is independent sealed, and be spliced into a complete body, a function casing of foremost is provided with front hermatic door, backmost a function casing is provided with rear hermatic door, respective separation and heat insulation door is provided with between adjacent function casing, make the structure that each function casing Inner Constitution independently seals, according to the function of function casing, corresponding function source established by each function casing, the inner bottom surface of described function casing is provided with and a upper station will be baked the transmitting device controlled by control device that object is sent to next station.The production line that this baking line can make existing new energy materials make, realizes pipelining.Want the streamlined operation realizing baking line, separation and heat insulation door (the transmission valve namely in the application) is very important, and namely it will have the effect of parting seal, has the effect that can be communicated with adjacent two function casings again.
The transmission valve (separate case proposes patent application) of the applicant's design, as shown in Figure 7 and Figure 8, transmission valve 1000 is between the first adjacent function casing 100 and the second function casing 200, for separating or being communicated with the first function casing 100 and the second function casing 200, comprise the seal closure 300 of the abutting end for sealing the first function casing 100 and the second function casing 200, be arranged at the first hermatic door 310 and the second hermatic door 320 in described seal closure 300, and hermatic door travel mechanism 330, described hermatic door travel mechanism 330 is set to when the first function casing 100 and the second function casing 200 need airtight, described first hermatic door 310 and the second hermatic door 320 open by described hermatic door travel mechanism 330, described first hermatic door 310 compresses the first sealing ring 340 be positioned on the first function casing 100 end face and is sealed by described first function casing 100, described second hermatic door 320 compresses the second sealing ring 350 be positioned on the second function casing 200 end face and is sealed by described second function casing 200, when the first function casing 100 needs to be communicated with the second function casing 200, what described first hermatic door 310 and the second hermatic door 320 were moved to described seal closure 300 by described hermatic door travel mechanism 330 dodges in space 3001, with realize the first function casing 100 and the second function casing 200 through, so that the baked article 400 in the first function casing 100 is transferred in the second function casing 200, obviously, the baked article 500 in the second function casing 200 also can transmit valve by another one transfers to down (not shown) in functional compartment body once.
Under normal circumstances, described hermatic door travel mechanism 330 includes but not limited to the gear 3302 that driven by motor 3301 and tooth bar 3303, and tooth bar 3303 is connected with described first hermatic door 310 and the second hermatic door 320 with second connecting rod 3305 respectively by first connecting rod 3304.
As everyone knows, each link of industrialization streamline operation must be its maximum productivity of competence exertion that normally works, and all can have an impact to its last process and next procedure if which link goes wrong, time serious, whole piece streamline all can pause.Tunnel type baking line is also like this, if the transmission valve 1000 between the first adjacent function casing 100 and the second function casing 200 goes wrong, can not rapid-maintenance, also can have influence on whole production line, and existing transmission valve 1000 is due to the reason of structure, must select when keeping in repair and remove seal closure 300, just can maintenance failure point, after fixing, then to again install seal closure 300, maintenance once generally needs 8-15 hour, and this pipeline operation is unallowed; How ensureing in 30 minutes, just can fix transmission valve 1000, is that tunnel type toasts line problem in the urgent need to address.
