DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Referring to Figures 1-3 A kind of even injection device for silane treating agent, including stirring drum 1, stirring assembly is arranged in stirring drum 1, stirring drum 1 bottom extends downward with discharge pipe 2, first valve 3 is fixedly installed in the middle of discharge pipe 2, injection cylinder 5 is fixedly connected with the two sides of the bottom end of discharge pipe 2 respectively by first connecting pipe 4, second valve 6 is fixedly installed at the bottom end of injection cylinder 5, ventilation hole 7 is formed in the top of injection cylinder 5, and ventilation assembly is arranged at ventilation hole 7.

[0025] Referring to Figures 3-4 Ventilation assembly includes sliding block 8 that is arranged in ventilation hole 7 up and down, the side of sliding block 8 is wavy, the high point of wavy shape realizes the limit of sliding block 8 in ventilation hole 7, and the low point of wavy shape realizes the ventilation between sliding block 8 and the side wall of ventilation hole 7.Sealing plate 9 is fixedly connected to the bottom of sliding block 8, and sealing plate 9 is lower than the top wall of injection cylinder 5, mounting plate 10 is fixedly connected to the top of sliding block 8, and a plurality of limiting blocks 11 are fixedly connected to the bottom surface of mounting plate 10 in circumferential array, and buoyancy ball 12 is fixedly connected to the bottom surface of sealing plate 9.

[0026] It further includes pressure balance assembly that communicates the lower parts of the two injection cylinders 5.

[0027] Referring to Figures 1-3 When using the even injection device for silane treating agent, first, silane treating agent is poured into stirring drum 1, stirring assembly is opened until silane treating agent is stirred evenly, then first valve 3 is opened, and silane treating agent is shunted into two injection cylinders 5 through two first connecting pipes 4, after completion, first valve 3 is closed, under the influence of pressure balance assembly, two injection cylinders 5 are communicated and make silane treating agent equal, then second valve 6 is opened, and the even injection of silane treating agent can be started.

[0028] When the silane treatment agent in the injection cylinder 5 is too much, the silane treatment agent drives the floating ball 12 to move upward, the sealing plate 9 moves upward and adheres to the inner top wall of the injection cylinder 5, thereby avoiding the silane treatment agent from escaping from the vent hole 7. At this time, the second valve 6 is opened until the silane treatment agent in the injection cylinder 5 returns to the appropriate position, the sliding block 8 moves downward under the influence of gravity until the bottom surface of the limiting block 11 adheres to the top surface of the injection cylinder 5, at this time, the gap between the side surface of the sliding block 8 and the vent hole 7 realizes the air pressure balance between the inside and outside of the injection cylinder 5.

[0029] Referring to Figure 2 , the stirring assembly comprises a stirring frame 13 rotatably arranged in the stirring cylinder 1, and a motor 14 fixedly arranged on the top surface of the stirring cylinder 1 and configured to drive the stirring frame 13 to rotate. The stirring frame 13 comprises a vertical rotating shaft and a plurality of horizontal stirring rods. The stirring assembly drives the rotating shaft to rotate through the motor 14, so as to realize the stirring of the silane treatment agent in the stirring cylinder 1 by the stirring rods.

[0030] In order to make the silane treatment agent in the stirring cylinder 1 completely flow out, the top surface of the injection cylinder 5 is lower than the bottom surface of the stirring cylinder 1, so as to avoid the silane treatment agent remaining in the stirring cylinder 1.

[0031] In order to make the silane treatment agent in the first connecting pipe 4 completely flow out, the first connecting pipe 4 is arranged in an inclined manner, and the inclined lower end of the first connecting pipe 4 is fixedly connected to the upper portion of the side surface of the injection cylinder 5.

[0032] The pressure balance assembly comprises a second connecting pipe 15 fixedly connected between the lower portions of the side surfaces of the two injection cylinders 5, and a third valve 16 arranged in the middle portion of the second connecting pipe 15. The pressure balance assembly realizes the communication between the two injection cylinders 5 through the second connecting pipe 15, so as to realize the pressure balance. After the first valve 3 is closed and before the second valve 6 is opened, the third valve 16 is closed, so as to ensure that the two injection cylinders 5 do not interfere with each other in the injection process, avoid affecting the injection consistency of the two injection cylinders 5 when the device is accidentally tilted during injection, and improve the treatment effect.

[0033] In order to make the silane treatment agent in the second connecting pipe 15 completely flow out, the middle portion of the second connecting pipe 15 is higher than the two ends.

[0034] Referring to Figure 1 , in order to facilitate personnel to monitor the injection amount, a scale bar 17 is arranged on the side surface of the injection cylinder 5, and the injection cylinder 5 is transparent. Since the scale bar 17 will be affected by the first connecting pipe 4 and the second connecting pipe 15, the bottom end of the scale bar 17 is higher than the top end of the second connecting pipe 15, and the top end of the scale bar 17 is lower than the bottom end of the first connecting pipe 4. In normal use, the liquid level of the silane treatment agent is located between the bottom end and the top end of the scale bar 17. At this time, since the silane treatment agent completely fills the second connecting pipe 15 and does not completely fill the first connecting pipe 4, the accuracy of the scale bar 17 is improved.

[0035] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
