Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the open mode sketch map of locking device of the present invention;
Fig. 3 is the vertical view of structure shown in Figure 1.
The specific embodiment
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Referring to Fig. 1, Fig. 2 and Fig. 3; The preferred embodiment of a kind of groove jar of the present invention shown in it airtight positive pressure cleaning device; Comprise the groove jar mouth 40 adaptive friction tops that are tightly connected 3 with said groove jar; On said friction top 3, be equipped with and lead to inner steam inlet duct 1-1 of groove jar and the blow-off pipe 2-1 that leads to the groove pot bottom; After malleation steam cleaned said groove jar inside through said steam inlet duct 1-1, waste liquid that is produced or waste gas were under the effect of jar internal pressure, via said blow-off pipe 2-1 drain tank jar.Wherein, said cleaning device also comprises and the groove jar mouth 40 of groove jar or the groove tank skin 4 adaptive friction top locking devices that link to each other of groove jar.
Friction top locking device of the present invention can produce the structure of locking to said groove jar mouth 40 or groove tank skin 4 with said friction top 3 for various.In the present embodiment, said locking device is included in the locked groove 3-1 that is provided with on the said friction top 3 and is arranged on the said groove tank skin 4 and the clamping screw 6 that matches with said locked groove 3-1, and is as shown in Figure 3.
The present invention isolates inboard the sealing with the outside of groove jar through said friction top locking device, and in the groove jar, squeezes into steam through steam inlet duct 1-1, carries out airtight cleaning; Simultaneously, the barotropic state that matter utilization groove jar inside such as the waste water after will cleaning via the blow-off pipe 2-1 that leads to the groove pot bottom, waste liquid, waste gas are in is automatically outside the drain tank.
Further preferably, cleaning device according to the invention includes locked groove 3-1 and the clamping screw 6 that many groups cooperatively interact, in the present embodiment; Be provided with 4 groups of locked groove 3-1 that cooperatively interact and clamping screw 6; As shown in figures 1 and 3, certainly, 3 groups or 6 groups or the like can be set also.The present invention can also be as required at the arranged outside bolt frame 61 of said groove jar mouth 40 or groove tank skin 4; This bolt frame 61 is rotatably connected through pivot and said bolt 6; When needs are opened friction top 3, only need each bolt 6 be turned on respectively, and push open laterally like this; Be discharged into free state, can open said friction top 3.And said bolt 6 still can be arranged on the bolt frame 61, so that when next time friction top 3 being installed, continues to accomplish the friction top locking action.
Above-mentioned bolt type friction top locking device of the present invention has installs advantages such as simple, with low cost, that effect is obvious.
Further, also be provided with at least two steam guide pipes 8 that are connected with steam inlet duct 1-1 in the bottom of steam inlet duct 1-1 of the present invention.Can get into the inner steam of groove jar by water conservancy diversion through steam guide pipe 8 of the present invention, and steam is gone out to peripheral jet flow, let steam begin condensation far just now from a jar mouth.Then, under the effect of malleation, steam can be full of whole groove jar, just solved thus in traditional carwash technology clean from jar mouthful some zone far away less than problem.
In order to improve sealing effectiveness between friction top 3 and the groove jar mouth 40, the present invention also is provided with sealing ring 5 on said friction top 3 or groove jar mouth 40, as depicted in figs. 1 and 2.
Further, also be provided with the safeguard protection assembly on the friction top 3 according to the invention.Said safeguard protection assembly comprises monitoring groove jar pressure inside mechanism for monitoring 7-2, the 7-3 of temperature monitoring mechanism and steam outlet 7-1.General groove tank car all is a low pressure vessel, and the operate high pressure during design is about 0.15MPa, and safeguard protection assembly of the present invention can guarantee that the groove pressure tank is controlled at below the 0.12MPa when positive Pressure-washing apparatus.If it is unusual; For example pressure surpasses 0.12MPa; Can open rapidly through the quick pressure releasing valve in the safeguard protection assembly; And carrying out pressure release through steam outlet 7-1, said structure of the present invention can the handled easily personnel can be observed pressure and temperature in the positive Pressure-washing apparatus at any time, and carries out manual discharge of steam where necessary.
The present invention has realized the positive-pressure closing steam clean of groove jar through above-mentioned groove jar airtight positive pressure cleaning device, makes that volatile substances can not volatilize away in atmosphere easily in steam and the groove jar.At certain direct draught, steam is fully condensation in jar, because the groove jar is in low-pressure state, the groove tank skin is heated comparatively evenly like this, has solved traditional uncovered steaming washing trough tank skin problem of non-uniform of being heated.In addition, owing to be in low-pressure state, the more traditional uncovered steaming washing trough temperature of groove jar internal temperature has improved degree (can regulate according to washing trough jar technology) more than 10-40 ℃.Because temperature improves, and makes cooking speed improve greatly.And,, also solved traditional uncovered steaming washing trough air pollution, waste of steam is big, car-cleaning cost is high problem because the groove jar is in the positive seal state.Further, because the groove jar is in the positive seal state, solved the high-decibel noise problem that a large amount of steam of traditional uncovered steaming washing trough spread generation rapidly.Therefore, the present invention also has advantages such as environmental protection, energy-conservation, efficient, low cost.
Obviously, those of ordinary skill in the art can use a kind of groove jar airtight positive pressure cleaning device of the present invention, constitutes various types of malleation cleaning devices.
Should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not to its restriction; Although with reference to preferred embodiment the present invention has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can specific embodiments of the invention make amendment or the part technical characterictic is equal to replacement; And not breaking away from the spirit of technical scheme of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
