Abstract
The invention relates to a vacuum insulation spinning box, which is mainly characterized in that a vacuum insulation mechanism is arranged outside a spinning box body and comprises an insulation shell which is coated outside the spinning box body and has an appearance similar to the appearance of the spinning box body, the shell is formed by welding a steel plate of 2-3mm, a basically identical gap is left between the insulation shell and the spinning box body, the insulation shell is also provided with a needle-shaped cut-off valve, one joint of the valve is connected with the insulation shell, and the other joint of the valve is connected with a vacuum pump. Due to the adoption of vacuum insulation, the invention has the advantages of low loss and good insulation effect, and not only can reduce the heat supplemented into the spinning box by about 30 percent, but also can decrease the production cost; the whole process of the manufacture of the spinning box and the production of the filament bundle causes no pollution to the human body and the environment; and the vacuum insulation spinning box is free of maintenance, thereby saving the maintenance cost.
Description
Technical field the present invention relates to a kind of equipment of processing and manufacturing synthetic fiber.
Background technology those skilled in the art knows that manifold is one of capital equipment of processing and manufacturing synthetic fiber, for guaranteeing the quality of synthetic fibre tows, must keep constant high temperature (more than 300 ℃) in this spinning manifold.For preventing its heat radiation, outside spinning manifold, be provided with heat preservation mechanism, this heat preservation mechanism is: be provided with the rock wool fibers layer outside spinning manifold, cover the iron sheet of one deck 1 millimeters thick in rock wool fibers layer outside.Its weak point is: 1. the principle of rock wool heat-preservation is that the heat conduction is slow, but also carries out the heat conduction, and it can make, and heat runs off in the manifold, and rule of thumb, heat runs off 30% approximately.Need heat medium additional heat in manifold constantly, this need consume the more energy for this reason.2. covering the outer iron sheet of rock wool each other can not be fixedly connected, and the position will change or come off when people trample or collide, so heat preservation mechanism will often keep in repair, and spends many maintenance costs.3., rock wool is a kind of to the virulent material of human body, and is not only toxic to the workman when the manifold heat-insulation layer is constructed, and rock wool fibers often exposes, it swims in the air, and is also toxic to the workman who produces tow.
Summary of the invention the object of the present invention is to provide the vacuum insulation spinning box of a kind of high insulating effect, energy-conservation, nuisanceless, freedom from repairs.
The present invention is provided with vacuum heat-preserving mechanism outside existing spinning manifold.This vacuum heat-preserving mechanism mainly includes insulation shell, support member and aciculiform stop valve.Wherein insulation shell is the housing that is coated on the basic and spinning manifold appearance similar in spinning manifold outside, this housing is to be welded by 2-3 millimeter steel plate, the parts intersection that insulation shell and spinning manifold stretch out body also is welded to connect, and makes the interlayer between spinning manifold and insulation shell become an annular seal space.Be provided with basic equidistant from distance between above-mentioned insulation shell and the spinning manifold, the size of this spacing will be selected according to the thermal capacity Q=cmt (Q thermal capacity, c specific heat, m quality, t temperature) of heat medium in the manifold, as thermal capacity when big, above-mentioned spacing is then big, otherwise just smaller, in general spacing is the 20-30 millimeter.For guaranteeing that above-mentioned spacing size is consistent and making insulation cladding physical efficiency bearing certain pressure, in the annular seal space of above-mentioned insulation shell and spinning manifold formation, be provided with the support member of interruption, this highly identical support member shape can have multiple, as flat board, orifice plate, deckle board and column etc., above-mentioned support member one end links to each other with manifold, and the relative other end links to each other with insulation shell.Above-mentioned insulation shell is provided with the aciculiform stop valve, and an interface of this valve links to each other with insulation shell, and another interface can link to each other with vavuum pump.During use, the valve rod of rotation aciculiform stop valve makes vavuum pump be connected with annular seal space between spinning manifold and the insulation shell by the aciculiform stop valve.Open vavuum pump and vacuumize operation.When vacuum reaches needed negative pressure value, then close vavuum pump.This negative pressure value is decided as required, as can on insulation shell, establishing temperature sensor or thermometer, insulation shell is observed, take all factors into consideration according to the actual conditions of each casing each side and establish the vacuum standard value, in general bigger good heat-insulation effect of vacuum, otherwise weak effect.
The present invention compared with prior art has following advantage:
1, vacuum heat-preserving heat loss is few, and high insulating effect can reduce additional heat in manifold, and is energy-conservation about 30%, reduced production cost simultaneously again.
2, vacuum heat-preserving is all without any side effects to human body with the overall process of producing tow in the manufacturing of manifold, and environment is not had any pollution yet, has really realized environmental protection.
3, the insulation shell profile is firm, avoids maintenance and has saved various maintenance costs.
4, vacuum pumping is simple, and portable vavuum pump just can be finished and vacuumize operation, and electricity consumption seldom.
Description of drawings
Fig. 1 is the main generalized section of looking of the present invention.
Fig. 2 is the enlarged diagram of A among Fig. 1.
The specific embodiment is looked in the generalized section the master of vacuum insulation spinning box shown in Figure 1, outside spinning manifold 1, be provided with vacuum heat-preserving mechanism, this heat preservation mechanism has the insulation shell 2 that is coated on spinning manifold outside (except the base) and spinning manifold appearance similar, this housing is by 3 millimeters airtight being welded of steel plate, and insulation shell and spinning manifold stretch out also airtight being weldingly connected in parts intersection of body.Be provided with 30 millimeters spacing between above-mentioned insulation shell and the spinning manifold.Be provided with the support member 3 of interruption in the annular seal space of above-mentioned insulation shell and spinning manifold formation, this highly identical flat support part one end links to each other with manifold, and the relative other end links to each other with insulation shell, as shown in Figure 2.Above-mentioned insulation shell is provided with aciculiform stop valve 4, is provided with valve rod 5 in the valve pocket of valve body, and the one end is positioned at the outer other end of valve body and is positioned at valve pocket, and an interface of this valve links to each other with insulation shell, and another interface 6 can link to each other with vavuum pump, as shown in Figure 2.
