For solving the problems of the technologies described above, the present invention adopts technical scheme to be: provide a kind of floatation and ink removing Self inhaling compound ejector, comprise compound jet pipe, described compound jet pipe is located at the side of induction chamber, the central authorities of described induction chamber are located in the outlet of described compound jet pipe, the opposite side of described induction chamber connects mixing chamber, described mixing chamber connects playpipe, wherein, described compound jet pipe comprises pulp import pipe, the first jet pipe and the second jet pipe, and described pulp import pipe, the first jet pipe are that nested, concentric is firmly connected with the second jet pipe ecto-entad; Described mixing chamber comprises slurry gas mixing chamber and one or more slurry gas homogenizing mixing chamber, and described slurry gas mixing chamber is connected with described induction chamber, and described slurry gas homogenizing mixing chamber is connected with described playpipe.
Further, the length of described second jet pipe is 3 ~ 50 millimeters, internal diameter is 2 ~ 20 millimeters.
Further, the length of described induction chamber is 5 ~ 50 millimeters, internal diameter is 2 ~ 20 times of described second jet pipe internal diameter.
Further, the length 2 ~ 50 millimeters of described slurry gas mixing chamber, internal diameter are 0.2 ~ 0.8 times of described induction chamber internal diameter.
Further, the length of described slurry gas homogenizing mixing chamber is 2 ~ 50 millimeters, internal diameter is 1.5 ~ 10 times of described slurry gas mixing chamber internal diameter.
The invention has the beneficial effects as follows: be different from traditional fresh air compressor floatation and ink removing equipment press-in air can not with slurry Homogeneous phase mixing, existing ejector velocity ratio when slurry passes through is lower, do not reach the effluxvelocity of high velocity jet, slurry is difficult to the eddy current forming various High Rotation Speed, make bubble fully can not arrest ink particle and tiny ink particle cannot be arrested, the situation of deinking efficiency difference, the compound jet pipe of the compound ejector of floatation and ink removing Self inhaling of the present invention can penetrate slurry at a high speed, produce negative pressure, automatic suction air enters induction chamber, slurry enters slurry gas mixing chamber in high-speed jet, slurry gas homogenizing mixing chamber, in the process of playpipe, the air sucked mixes more even with slurry, and form the different eddy current of various High Rotation Speed, make bubble fully arrest ink particle and tiny ink particle can be arrested, deinking efficiency is good.
Accompanying drawing explanation
Fig. 1 is the profile of the compound ejector of floatation and ink removing Self inhaling of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the compound ejector of floatation and ink removing Self inhaling of the present invention comprises compound jet pipe 1, induction chamber 2, mixing chamber 4 and playpipe 5, the side being located at induction chamber 2 of compound jet pipe 1, the central authorities of induction chamber 2 are located in the outlet of compound jet pipe 1, the sidewall of induction chamber 2 is provided with air entry 3, the opposite side of induction chamber 2 connects mixing chamber 4, and mixing chamber 4 connects playpipe 5.Compound jet pipe 1 comprises pulp import pipe 11, first jet pipe 12 and the second jet pipe 13, pulp import pipe 11, first jet pipe 12 is that nested, concentric is firmly connected with the second jet pipe 13 ecto-entad, and the length of the second jet pipe 13 is 3 ~ 50 millimeters, internal diameter is 2 ~ 20 millimeters; Mixing chamber 4 comprises slurry gas mixing chamber 41 and one or more slurry gas homogenizing mixing chamber 42, slurry gas mixing chamber 41 is connected with induction chamber 2, slurry gas homogenizing mixing chamber 42 is connected with playpipe 5,2 ~ 20 times that the length of induction chamber 2 is 5 ~ 50 millimeters, internal diameter is the second jet pipe 13 internal diameter, 0.2 ~ 0.8 times that the length of slurry gas mixing chamber 41 is 2 ~ 50 millimeters, internal diameter is induction chamber 2 internal diameter, 1.5 ~ 10 times that the length of slurry gas homogenizing mixing chamber 42 is 2 ~ 50 millimeters, internal diameter is slurry gas mixing chamber 41 internal diameter.
The operation principle of the compound ejector of floatation and ink removing Self inhaling of the present invention:
The pressure that slurry is produced by centrifugal pump enters pulp import pipe 11 by certain flow velocity, then the first jet pipe 12 is entered, because the internal diameter of the first jet pipe 12 is less than pulp import pipe 11, slurry is improved further by flow velocity after the first jet pipe 12, disposed slurry enter the second jet pipe 13, internal diameter due to the second jet pipe 13 is less than the first jet pipe 12, in like manner, slurry is improved again by flow velocity after the second jet pipe 13, the slurry of injection makes induction chamber 2 produce negative pressure at a high speed, thus automatically suck air, air enters induction chamber 2 by air entry 3, slurry and air enter starches gas mixing chamber 41, in slurry gas mixing chamber 41, slurry tentatively mixes with air, enter slurry gas homogenizing mixing chamber 42 afterwards, internal diameter due to slurry gas homogenizing mixing chamber 42 is greater than the internal diameter of slurry gas mixing chamber 41, after slurry enters slurry gas homogenizing mixing chamber 42, pressure declines suddenly formation negative pressure, flow rate of slurry reduces suddenly and forms strong eddy current, make the bubble in slurry and slurry fully contact and catch and grab ink, slurry is finally sprayed by playpipe 5.
