DETAILED DESCRIPTION

[0017] 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, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figures 1-4 The utility model provides a kind of technical scheme of flame retardant feeding device, including cylinder 1, the cylinder 1 is provided with feeding port 11, stirring mechanism is provided in the cylinder 1, the stirring mechanism includes shaft 15, the top of the shaft 15 is connected with motor 14, the shaft 15 is provided with fixed block 16, multiple stirring paddles 17 are distributed with equal distance in the side of the fixed block 16, the bottom end of the shaft 15 is connected with driving cone gear 19, which is penetrated through the top wall of drive box 18, the bottom wall of the drive box 18 is fixedly connected with cylinder 1 by fixed column 3, the side of driving cone gear 19 is engaged with driven cone gear 2, the side of driven cone gear 2 is coaxially connected with auxiliary stirring roller 21, the auxiliary stirring roller 21 is provided with helical feed piece 22, the side of cylinder 1 is connected with discharge pipe 23, the bottom opening of the discharge pipe 23 is provided with detachable discharge nozzle 24 by connecting mechanism, the discharge nozzle 24 is provided with filter assembly.

[0019] Adopt the stirring mode of combination of stirring paddle 17 and auxiliary stirring roller 21 with helical feed piece 22.Electric motor 14 drives shaft 15 to rotate, so that stirring paddle 17 carries out primary stirring to flame retardant, while driving cone gear 19 drives driven cone gear 2 and auxiliary stirring roller 21 to rotate, and helical feed piece 22 pushes material to circulate in the process of rotation, so that secondary stirring to flame retardant is realized.This double stirring structure effectively avoids stirring dead angle, so that flame retardant and other additives can be fully mixed, greatly improves stirring mixing effect, and ensures that the flame retardation performance of final product is stable.

[0020] Discharge nozzle can be disassembled and cleaned: discharge nozzle 24 is screwed with the threaded hole 26 in the bottom of discharge pipe 23 by screw joint 25, and this connection mode makes that discharge nozzle 24 can be disassembled.When discharge nozzle 24 is blocked by impurities in flame retardant, the entire discharge system does not need to be disassembled, and only needs to be simply unscrewed, so that the coarse sieve screen 27 and fine filter microporous plate 28 in it can be cleaned or replaced.This design greatly improves cleaning efficiency, reduces downtime caused by nozzle blockage, ensures the continuity of production, and reduces maintenance cost.

[0021] In the above scheme, the lower portion of the cylinder 1 is provided with a support column 12, and the support column 12 is arranged in the liquid collecting pan 13.

[0022] In the above scheme, the housing of the motor 14 is fixed above the cylinder 1.

[0023] In the above scheme, the shaft 15 and the auxiliary stirring roller 21 are respectively rotatably connected with the drive box 18 through bearings.

[0024] The connecting mechanism comprises a screw joint 25 arranged on the top of the discharging nozzle 24, which is screwed into a threaded hole 26 on the bottom of the discharging pipe 23.

[0025] The filter assembly comprises a coarse filter screen 27 and a fine filter micro-porous plate 28. The coarse filter screen 27 and the fine filter micro-porous plate 28 play a crucial role in filtering. The coarse filter screen 27 is arranged near the discharging pipe 23 and has large mesh holes, which are mainly used for intercepting large-particle impurities in the flame retardant, such as undissolved blocks and mixed foreign matters. If these large-particle impurities directly enter the fine filter micro-porous plate 28, the fine filter micro-porous plate 28 will be blocked quickly, which will affect the overall filtering efficiency and discharging effect. The coarse filter screen 27 is made of high-strength and corrosion-resistant metal material, and the mesh hole size is carefully designed and tested, which can effectively filter large impurities without causing too much obstruction to the flow rate of the flame retardant.

[0026] The fine filter micro-porous plate 28 is arranged downstream of the coarse filter screen 27, that is, closer to the outlet of the discharging nozzle 24. It has extremely small micro-porous diameter, which can filter out extremely fine particles and small impurities that cannot be intercepted by the coarse filter screen 27, further ensuring the purity of the sprayed flame retardant. The fine filter micro-porous plate 28 is usually made of special micro-porous ceramic or high-performance polymer material, which has good filtering precision and chemical stability and will not react with the flame retardant, ensuring that the performance of the flame retardant is not affected.

[0027] In the above scheme, the edge of the liquid collecting disc 13 is provided with a discharging valve.

[0028] Working principle:

[0029] The feeding device of the flame retardant is first placed in a suitable position to ensure that the supporting column 12 stably supports the cylinder 1 and the liquid collecting disc 13 is properly placed. The flame retardant and other additives are added into the cylinder 1 through the feeding opening 11.

[0030] The electric motor 14 is started, the electric motor 14 drives the rotating shaft 15 to rotate, the stirring paddle 17 on the rotating shaft 15 starts to stir the materials in the cylinder. At the same time, the driving bevel gear 19 at the bottom end of the rotating shaft 15 rotates to drive the driven bevel gear 2 and the auxiliary stirring roller 21 coaxial with the driven bevel gear 2 to rotate. The spiral feeding piece 22 on the auxiliary stirring roller 21 pushes the materials to flow in the cylinder and further stirs the materials during the rotation process, so that the flame retardant and other additives are fully mixed.

[0031] When the discharge is needed, the mixed flame retardant flows to the discharge nozzle 24 through the discharge pipe 23, and the coarse filter screen 27 and the fine filter microporous plate 28 filter the flame retardant in the discharge nozzle 24, so as to ensure that the sprayed flame retardant is uniform and free of impurities. If it is found that the discharge of the discharge nozzle 24 is not smooth or is blocked, the discharge nozzle 24 can be disassembled for cleaning or replacement by rotating the discharge nozzle 24, so that the screw joint 25 is unscrewed from the threaded hole 26 at the bottom of the discharge pipe 23. After cleaning, the discharge nozzle 24 is reinstalled, and the screw joint 25 is tightened to continue use; if the flame retardant drips during use, it will fall into the liquid collecting pan 13, and the collected liquid can be discharged through the discharge valve at the edge of the liquid collecting pan 13 at regular intervals to keep the working environment clean.

[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
