The modified resin is difficult to be fully mixed unless the stirring is quite violent. Moreover, a long time is needed for stirring to ensure full mixing, and the standard time for stirring is difficult to determine.

[0004] Moreover, violent stirring easily makes the solvent and solute volatile at a high speed. Even if the solvent has the characteristic of high flash point, the solvent is still troublesome and has great safety hazards in the case of contacting air. SUMMARY

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown, the present invention includes an inlet 101, an external fixed tube 102, a support frame 103, a flexible tube 104, a rigid tube 105, an outlet tube 106, and a spherical tube 109. Multiple spherical tubes 109 are provided and connected to each other by connecting tubes 110. An outlet 113 is provided on the side wall of the lowermost connecting tube 110. The inlet 101 is connected to the uppermost spherical tube 109.

[0023] Multiple external fixing tubes 102 are provided and fixedly connected to the support frame 103. A flexible tube 104 is provided between adjacent external fixing tubes 102. The rigid tube 105 is fixedly connected to the lowermost external fixing tube 102. The discharge tube 106 is fixedly connected to the uppermost external fixing tube 102. The flexible tube 104, rigid tube 105 and discharge tube 106 are sleeved on the ball tube 109 and the connecting tube 110 and are interconnected. The lowermost connecting tube 110 is connected to the rigid tube 105 through the liquid outlet 113.

[0024] An internal fixation tube 111 is also fixed inside the external fixation tube 102. A spherical component 114 is provided inside the spherical tube 109. The internal fixation tube 111 passes through the spherical tube 109 and is fixedly connected to the spherical tube 109 and the spherical component 114. A liquid spraying port 115 is also provided on the upper side of the internal fixation tube 111 between the spherical tube 109 and the spherical component 114.

[0025] Particularly, the spherical member 114 is internally provided with a closed inner cavity 117, the connecting sliding block 118 is slidingly connected in the closed inner cavity 117, the upper end of the connecting sliding block 118 is fixedly connected with the extending rod 119, the upper end of the extending rod 119 is fixedly connected with the arc-shaped plate 120, the arc-shaped plate 120 is a metal plate, and the top of the spherical tube 109 is provided with the permanent magnet 116 corresponding to the arc-shaped plate 120, the lower end of the connecting sliding block 118 is fixedly connected with the connecting sliding rod 123, the connecting sliding rod 123 is externally provided with the spring 124, and the upper and lower ends of the spring 124 are respectively connected to the connecting sliding block 118 and the fixed plate 122 at the bottom of the closed inner cavity 117. The spherical member 114 below the fixed plate 122 is further provided with the open inner cavity 121, the open inner cavity 121 is open at the bottom, the piston plate 125 is slidingly connected in the open inner cavity 121, the piston plate 125 is fixedly connected to the lower end of the connecting sliding rod 123, and the connecting sliding rod 123 passes through and is slidingly connected with the fixed plate 122.

[0026] Therefore, when the modified resin moves in the spherical tube 109, the modified resin is flattened on the outer surface of the spherical member 114 in the spherical tube 109, and the solvent is quantitatively sprayed in the proportion in the liquid spraying port 115 on the inner fixed tube 111 between the spherical tube 109 and the spherical member 114, so that the mixing of the modified resin and the solvent is promoted, and finally the desired modified water-based paint is mixed.

[0027] When entering the next spherical tube 109, the piston plate 125 reciprocates up and down once, which plays a role in pushing and pulling the viscous mixed solvent, and promotes the mixing and dispersion of the mixed solvent. The pushing process of the piston plate 125 causes the modified resin in the next connecting tube 110 to enter the next spherical tube 109 in the form of spraying, thereby improving the dispersion effect.

[0028] In addition, the outer side of the hose 104 is provided with the pump liquid cam 108 connected to the output shaft of the driving motor.

[0029] The pump liquid cam 108 on the outer side of the hose 104 is continuously rotated, so that an upward hydraulic pressure is formed in the hose 104, the modified resin is promoted to flow, and finally exits through the discharge pipe 106.

[0030] In addition, the connecting part of the hose 104 and the pump liquid cam 108 is fixedly connected with the connecting rod 126, and the other end of the connecting rod 126 is fixedly connected with the liquid mixing plate 112.

[0031] Therefore, during the continuous rotation of the pump cam 108, the pump cam 108 continuously pushes the hose 104 to deform, and the hose 104 deforms to retract and drive the mixed liquid plate 112 to act, and the mixed liquid plate 112 continuously acts to stir the final modified water-based paint, which plays a role of stirring and dispersing.

[0032] DETAILED DESCRIPTION AND PRINCIPLES

[0033] First, the modified resin is input into the spherical tube 109 through the liquid inlet 101, wherein the spherical tube 109 and the connecting tube 110 are arranged vertically as a whole, vertically downward, and the modified resin moves downward in the spherical tube 109 and the connecting tube 110 under the action of its own gravity and hydraulic pressure,

[0034] During the input and movement of the modified resin, after a certain amount of modified resin accumulates in the connecting tube 110 connected to the liquid inlet 101, the gravity of the modified resin is greater than the attraction between the permanent magnet 116 and the arc-shaped plate 120 and the elastic force of the spring 124, the permanent magnet 116 and the arc-shaped plate 120 are separated, and the opening is exposed, so that the modified resin can smoothly enter the next spherical tube 109.

[0035] After a certain amount of modified resin is discharged, the arc-shaped plate 120 is reset under the elastic force of the spring 124, and in this process, the piston plate 125 in the opening inner cavity 12 at the bottom of the spherical part 114 also reciprocates up and down, thereby pushing and pulling the viscous modified resin, promoting the mixing and dispersion of the modified resin.

[0036] In addition, the upward movement of the piston plate 125 will bring the viscous modified resin into the opening inner cavity 121, and when the piston plate 125 moves downward, it will push the viscous modified resin to quickly leave the opening inner cavity 121 and quickly enter the next connecting tube 110, so that the hydraulic pressure in the next connecting tube 110 suddenly rises, and then the modified resin in the next connecting tube 110 enters the next spherical tube 109 in the form of jet, improving the dispersion effect.

[0037] When the modified resin moves in the spherical tube 109, the modified resin will be spread on the outer surface of the spherical part 114 in the spherical tube 109 and flow down along the outer surface of the spherical part 114, and the solvent mixed with the modified resin will be sprayed from the liquid outlet 115 on the inner fixed tube 111 between the spherical tube 109 and the spherical part 114 in proportion to the amount, and the sprayed solvent can better mix with the modified resin, which plays a better dispersion role, and after leaving the liquid outlet 113, the desired modified water-based paint is formed.

[0038] And the modified water-based paint from the last spherical tube 109, through the lowermost connecting pipe 110 liquid outlet 113 into the hard tube 105, and by hydraulic pressure to move into the hose 104, due to the pump liquid cam 108 is constantly rotating, so that the hose 104 form a similar to peristaltic pump upward hydraulic pressure, promote the modified resin flow, and finally through the discharge pipe 106 exit. And in this process, due to the pump liquid cam 108 constantly rotating, the pump liquid cam 108 will constantly push the hose 104 deformation, and the hose 104 deformation shrink and drive the mixing plate 112 action, mixing plate 112 constantly stirring the final modified water-based paint, play a stirring dispersion effect.

[0039] Based on the above, the present application by a variety of ways to promote mixing, coordination and synchronization of high flash point diluent mixing and dispersion, improve the dispersion effect. Including flat flow: diluent along the spherical outer wall flow; injection: solvent mixed with the modified resin by injection and mixed paint into the next spherical tube by injection; push and pull; stirring, etc. Each way through the diluent flow with the corresponding structure to achieve without adding various equipment, and using the flow of diluent, in the process of gradually mixed operation, improve the overall efficiency.

[0040] From the technical common sense, the present application can be realized by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments, in all aspects, are only illustrative and not restrictive. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
