Accompanying drawing explanation
Fig. 1 is for repairing the structural representation of the spray gun of refractory material in the present invention.
Detailed description of the invention
With reference to Fig. 1, for repairing the spray gun of refractory material, the powder pipe 2 comprising shower nozzle 1 and be connected with shower nozzle 1, refractory powder enters in shower nozzle 1 by feed pipe 2, the sidewall of shower nozzle 1 is provided with water inlet 121, water enters in shower nozzle 1 by water inlet 121, to realize water and refractory powder is mixed into fireproof coating in shower nozzle 1.
With reference to Fig. 1, for increasing the area that water directly contacts with refractory powder, mixing device is provided with in the shower nozzle 1 of the present embodiment, mixing device comprises conduit assembly, described conduit assembly comprises the flow pipe 3 and some points of branching pipes 4 that are connected with water inlet 121, some points of branching pipes 4 are connected on flow pipe 3, divide on branching pipe 4 and be provided with some apopores 41, after water in water inlet 121 flows through flow pipe 3 and point branching pipe 4 successively, enter in shower nozzle 1 from apopore 41, mix with refractory powder to realize water.
In this structure, the existence of point branching pipe can increase the area that water directly contacts with refractory powder, but even if divide a branching pipe to set out water hole, the quantity of apopore is also limited, and therefore, the refractory powder of diverse location and the mixability of water are also different.In the present embodiment, for realizing water and refractory powder Homogeneous phase mixing, described mixing device also comprises at least one block of batch mixing plate.
With reference to Fig. 1, concrete, the inwall of shower nozzle 1 between conduit assembly and nozzle is provided with annular protrusion 122 and some first lock teeth 123, the thickness that annular protrusion 122 and first locks gap between tooth 123 and batch mixing plate 5 is basically identical.Batch mixing plate 5 is provided with can with first lock tooth 123 sealed second lock tooth 52, batch mixing plate 5 inserts shower nozzle 1, and the end face of batch mixing plate 5 and annular protrusion 123 against time, rotate batch mixing plate 5 can realize the first lock tooth 123 and second to lock tooth 52 sealed, batch mixing plate 5 can be fixed in shower nozzle 1 by this structure, to realize disconnecting the pipeline of shower nozzle 1 between conduit assembly and nozzle.Batch mixing plate 5 is provided with some batch mixing holes 51, at disconnection shower nozzle 1 between conduit assembly and nozzle when pipeline, shower nozzle 1 is positioned at the refractory powder of conduit assembly one end and water can only enter by batch mixing hole 51 tube wall that shower nozzle 1 is positioned at nozzle one end, therefore, refractory powder and water realize first time by batch mixing hole 51 and mutually mixs, to be undertaken that second time is mutual to be mixed at the fireproof coating after first time batch mixing by nozzle.Through twice mutually mixing fireproof coating more than the fireproof coating only through mixed once mix more even.
Certainly, for obtaining the more uniform fireproof coating of batch mixing, the batch mixing plate of at least two pieces can be set in shower nozzle.
With reference to Fig. 1, for convenience of rotating batch mixing plate 5, lock the sealed of tooth 52 to realize the first lock tooth 123 with second or be separated, the end face of batch mixing plate 5 towards the second lock tooth 52 is provided with operating grip 53, operating grip 53 conveniently can order about batch mixing plate 5 and rotate relative to the first lock tooth 123.
With reference to Fig. 1, because fireproof coating has viscosity, when spray gun is used to complete, needs cleaning batch mixing plate 5 and point branching pipe 4, blocked by fireproof coating to avoid batch mixing hole 51 and apopore 41.Based on this reason, in the present embodiment, shower nozzle 1 comprises head body 11 and mixing tube 12, and water inlet 121, annular protrusion 122 and the first lock tooth 123 are arranged in mixing tube 12 respectively.Meanwhile, for reducing the manufacture difficulty of mixing tube 12, the first lock tooth 123 is connected by screw with mixing tube 12.
In the present embodiment, flow pipe end is provided with bending section, and some points of branching pipes are arranged on bending section respectively, this structure for increasing shower nozzle on cross section, the area that water and refractory powder directly contact.
In the present embodiment, batch mixing hole is greater than the aperture of batch mixing hole towards nozzle one end towards the aperture of conduit assembly one end, and this structure can avoid fireproof coating to paste on batch mixing hole, thus by batch mixing hole plug.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and those of ordinary skill in the art should be understood that and the present invention includes but be not limited to accompanying drawing and the description content above in detailed description of the invention.But any amendment not departing from function and structure principle of the present invention all will comprise within the scope of the appended claims.
