Abstract
The utility model discloses a gas circuit switching device capable of supplying air for a rotating air cylinder in the premixer. The gas circuit switching device comprises a switching base; an air inlet channel and an air return channel are arranged in the switching base; a movable switching ring is movably arranged on the outer side walls of the air inlet of the air inlet channel and the air outlet of the air return channel in a sealed way; an annular air inlet cavity and an annular air return cavity which are mutually isolated are arranged in the movable switching ring; and the annular air inlet cavity is communicated with the air inlet of the air inlet channel; the annular air return cavity is communicated with the air outlet of the air return channel; a connecting seat is fixedly arranged on the outer side of the movable switching ring; the connecting seat is provided with an air inlet joint communicated with the annular air inlet cavity, and an air return joint communicated with the annular air return cavity; the air outlet of the air inlet channel is connected with an air intake; the air inlet of the air return channel is connected with an air return pipe. The gas circuit switching device can be broadly used in premixers.
Description
Technical field
The utility model relates to premix machine field, especially the gas path switching device in the premix machine.
Background technique
The premix machine is mainly used to mix producing required various materials, its groundwork process is: material is packed in the mixing charging basket of premix machine, to mix the charging basket jacking to desired location by cylinder, mixing charging basket then does forward and backwardly to wave and rotatablely move under the effect of drive unit simultaneously, meanwhile, be arranged on the paddle that mixes the charging basket top and in charging basket, ceaselessly stir, finally realize the purpose of homogeneous mixture of material.Because cylinder rotates together along with mixing charging basket in the working procedure, must could be connected therefore for the tracheae of cylinder air feed by a swivel joint with the cylinder of rotation, but common swivel joint can not directly be used in the premix machine.
The model utility content
Technical problem to be solved in the utility model is: will provide a kind of can be to the gas path switching device of the rotary cylinder air feed in the premix machine.
For solving the problems of the technologies described above, the gas path switching device that is used for the premix machine described in the utility model, comprise a switching base, be provided with gas-entered passageway and return gas channel in the switching base, movable adapter ring is movable and be arranged on hermetically on the outer side wall of air outlet of the suction port of gas-entered passageway and return gas channel, be provided with isolated mutually annular inlet chamber and annular return-air chamber in the movable adapter ring, and annular inlet chamber communicates with the suction port of gas-entered passageway, and annular return-air chamber communicates with the air outlet of return gas channel; The outside at movable adapter ring is fixed with connecting base, be provided with intake interface that communicates with annular inlet chamber and the return-air interface that communicates with annular return-air chamber in the connecting base, the air outlet of gas-entered passageway is connected with suction tude, and the suction port of return gas channel is connected with muffler.
The beneficial effects of the utility model are: use above-mentioned gas path switching device in the premix machine, just can realize giving the purpose of rotary cylinder air feed.
Description of drawings
Fig. 1 is the structural representation of gas path switching device described in the utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the described gas path switching device that is used for the premix machine, comprise a switching base 1, be provided with gas-entered passageway 3 and return gas channel 2 in the switching base 1, movable adapter ring 4 is movable and be arranged on hermetically on the outer side wall of air outlet of the suction port of gas-entered passageway 3 and return gas channel 2, be provided with isolated mutually annular inlet chamber 42 and annular return-air chamber 41 in the movable adapter ring 4, and annular inlet chamber 42 communicates with the suction port of gas-entered passageway 3, and annular return-air chamber 41 communicates with the air outlet of return gas channel 2; Be fixed with connecting base 5 in the outside of movable adapter ring 4, be provided with intake interface 52 that communicates with annular inlet chamber 42 and the return-air interface 51 that communicates with annular return-air chamber 41 in the connecting base 5, the air outlet of gas-entered passageway 3 is connected with suction tude 31, and the suction port of return gas channel 2 is connected with muffler 21.
The working principle of the gas path switching device of said structure is: during use, the base 1 of will transferring is fixed together with cylinder 6, and suction tude 31 is connected with a ventilating hole of cylinder 6, and muffler 21 is connected with another ventilating hole of cylinder 6.When cylinder 6 rotations, switching base 1 is and then rotation together also in the work, and movable adapter ring 4 and connecting base 5 then maintain static; To be connected with intake interface 52 to a tracheae of cylinder air feed, another root tracheae is connected with return-air interface 51.Like this, even cylinder 6 and switching base 1 are not stopping rotation, still can pass through annular inlet chamber 42 and annular return-air chamber 41 and gas-entered passageway 3, suction tude 31 and return gas channel 2 and muffler 21 all the time to the gas circuit of cylinder 6 air feed and keep being communicated with, make cylinder 6 energy proper functioning with cylinder 6.
