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.
The specific embodiment
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Referring to Fig. 1; The preferred embodiment of the blocking mechanism of a kind of groove jar of the present invention shown in it malleation cleaning equipment; Comprise the groove jar mouth 40 adaptive friction tops that are tightly connected 3 with the groove jar; Be equipped with on the said friction top 3 and lead to groove jar inner steam inlet duct 1-1 and blow-off pipe 2-1; Also be provided with air valve retaining mechanism 6 on said steam inlet duct 1-1 or the blow-off pipe 2-1, the inboard of said air valve retaining mechanism 6 is connected with said steam inlet duct 1-1, and the outside of air valve retaining mechanism 6 is connected with the groove tank skin 4 adaptive closures of said groove jar.
When malleation was cleaned, steam pressure promotes said piston plate 6-5 stretched out said extensible member 6-1, and adaptive closed and locked with said groove tank skin 4.Particularly; In use; At first blocking mechanism of the present invention is put in the groove jar mouth 40 of groove jar, got into through steam inlet duct 1-1 in the inner process of groove jar at malleation steam then through hanging device, protruding with the air valve retaining mechanism 6 that said steam inlet duct 1-1 is connected.Along with the increase of steam pressure, the distance of stretching out increases gradually, is connected with the groove tank skin 4 adaptive closures of said groove jar until the outside of air valve retaining mechanism 6, accomplishes block action thus.Preferably, the bottom of extensible member 6-1 of the present invention has certain rigid, makes that it is to having mutual locking action power between friction top 3 and the said groove jar mouth 40 behind the completion block action; Simultaneously, preferably, the axial top of said extensible member 6-1 and said groove jar mouth 40 is acute angle, so that described locking action power secure more.
Preferably; Air valve retaining mechanism 6 according to the invention comprises the vapor chamber 6-4 that is connected with said steam inlet duct 1-1, through the extensible member 6-1 that piston plate 6-5 and said vapor chamber 6-4 link to each other at interval, the far-end of said extensible member 6-1 is connected with said groove tank skin 4 adaptive closures.
More preferably, also be provided with spring 6-2 between said extensible member 6-1 and the said piston plate 6-5, in the process of using; Steam in the steam inlet duct 1-1 is full of vapor chamber 6-4 gradually; And along with the increase of pressure, promote piston plate 6-5 and move laterally, promote said extensible member 6-1 thus further and move laterally; The far-end of final extensible member 6-1 is connected with the groove tank skin 4 adaptive closures of said groove jar, accomplishes block action thus.
And reset when unblanking at needs, stop to infeed steam, and along with the decline of steam pressure, extensible member 6-1 of the present invention resets gradually to steam inlet duct 1-1.In the present embodiment; Through spring 6-2 piston plate 6-5 is produced reverse motive force; Move to vapor chamber 6-4 direction; Make the far-end of extensible member 6-1 and the groove tank skin 4 of said groove jar be separated from each other thus, and make blocking mechanism of the present invention reach the safe escape distance, thereby accomplish the release action with respect to groove jar mouth 40.
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 shown in Figure 1.
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 the blocking mechanism of above-mentioned groove jar malleation cleaning equipment, 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 the blocking mechanism of a kind of groove jar malleation cleaning equipment of the present invention, constitutes various types of blocking mechanisms.
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.
