[0002] A flame retardant is a material added to flammable materials to inhibit combustion or reduce flame spread. Flame retardants can exert their flame retardant effects through various mechanisms, such as inhibiting heat transfer, covering the fire source, reducing the oxygen content, etc. During the flame retardant processing, a grinding device is required to process it into particles of a set particle size.

[0003] A flame retardant processing and grinding device and a grinding method with the publication number of CN118874613A improve the grinding efficiency and grinding effect of the flame retardant in a manner similar to an air mill. However, inside its roller, some of the grinding media continuously blown by high-pressure air nozzles at a fixed angle will accumulate at the corner positions of the inner wall of the roller and will not disperse as the roller rotates, resulting in a poor grinding effect of the applied grinding media. Therefore, improvements are needed. Summary of the Invention

[0019] Further, the drainage component includes,

[0020] A side cylinder shell, one side of the inner wall of the side cylinder shell close to the cylinder body component is in rolling connection with the outer surface of the outer rotating rod shell;

[0021] A pressure pump, the outer surface of the pressure pump is slidably connected to the center of the inner wall of the side cylinder shell, and the top end of the air outlet of the pressure pump is inserted into one end of the hollow inner cylinder, and the pressure pump can rotate relative to the hollow inner cylinder;

When the rotating cam rotates, it will periodically knock on the impact block, so that the wall-attached shell vibrates.

[0035] The beneficial effects of the present invention are as follows:

[0036] 1. The device can carry out ball milling work on the input flame retardant through the special nozzles inside and the self-rotating cylinder component. When the special nozzles spray air on the flame retardant particles inside the cylinder component, the filtering nozzle part will rotate as the spherical shell deflects, thereby achieving the effect of changing the spraying angle. Therefore, the airflow angle sprayed by the filtering nozzle is constantly changing, and the flame retardant inside the cylinder component will not gather at a fixed position inside the cylinder component due to the air spraying action of the special nozzles, resulting in caking and insufficient grinding problems.

[0037] 2. During the rotation of the cylinder, the internal grinding balls will roll, thereby grinding and refining the flame retardant contained inside. Since the special nozzle is not fixed on the outer rotating rod shell, when the rotation speed of the cylinder is too fast, the internal grinding balls may fly and then hit the filter nozzle of the special nozzle. At this time, the filter nozzle will drive the spherical shell to deflect, thereby achieving a force unloading effect and avoiding the problem of the fixed filter nozzle being bent, deformed or even broken due to the impact of the grinding balls.

[0038] 3. The internal blowing component of the device can rotate synchronously with the cylinder component, and can also change the function of controlling the motor speed to make the internal blowing component rotate in the opposite direction relative to the cylinder component, thereby accelerating the rotation angular velocity of the internal blowing component in disguise, so that the special nozzle can quickly blow off the material residue attached to the inner wall of the containing cylinder, and then the material residue contacts the grinding ball for refinement, thereby ensuring that the material residue has sufficient grinding time and ensuring that the flame retardant particles are relatively fine as a whole.

[0039] 4. Ball milling is performed inside the accommodating tube. The rotating motor inside the shell attached to the wall on both sides controls the rotating cam to rotate continuously, so that the shell attached to the wall on the side vibrates continuously by the rotating cam hitting the impact block, so that the flame retardant gathered on both sides of the inner wall of the accommodating tube is shaken and dispersed, and gathered to the middle position of the accommodating tube, and then blown away by a special nozzle, thereby avoiding the problem of the side part of the accommodating tube gathering the grinding ball shell flame retardant particles due to centrifugal force, and ensuring that the whole material is gathered in the middle grinding area for effective processing.

[0052] Example 1, please refer to Figures 1 - 6 , the present invention provides a technical solution: a flame retardant processing and frosting device, including:

[0053] A cylinder component 1, the inside of which is filled with grinding balls and flame retardant particles;

[0054] A suspension component 4, arranged on the ground, controlling the cylinder component 1 to roll, so that the grinding balls inside the cylinder component 1 perform ball milling;

[0055] The cylinder component 1 includes:

[0056] An internal air blowing component 2, arranged at the axis of the internal air blowing component 2, and both ends of the internal air blowing component 2 extend to the outside of the cylinder component 1, blowing air to the flame retardant particles inside the cylinder component 1;

[0057] A drainage component 3, pressurizing the inside of the internal air blowing component 2, so that the internal air blowing component 2 blows air into the inside of the cylinder component 1.

[0058] The inner air-blowing component 2 includes,

[0059] An outer rotating rod shell 21, at both ends of the inner wall of the outer rotating rod shell 21, embedded balls 24 are symmetrically arranged, and spherical embedding grooves are evenly formed in the middle of the inner cavity of the outer rotating rod shell 21;

[0060] A hollow inner cylinder 22, the hollow inner cylinder 22 is arranged at the axis of the outer rotating rod shell 21, and both ends of the hollow inner cylinder 22 extend to the outside of the outer rotating rod shell 21, and the outer surface of the hollow inner cylinder 22 is in mutual extrusion with the outer surface of the embedded ball 24;

[0061] A special nozzle 25, the special nozzles 25 are evenly arranged on the outer surface of the hollow inner cylinder 22, and one end of the special nozzle 25 far from the hollow inner cylinder 22 extends to the outside of the outer rotating rod shell 21;

[0062] A protective end sleeve 23, at the axis of the inner wall of the protective end sleeve 23, it is fixedly connected to the outer surface of the outer rotating rod shell 21, and the middle of the inner cavity of the protective end sleeve 23 is rotationally connected to the inner cavity of the cylinder component 1 through a circumferential cutting groove.

[0063] The special nozzle 25 includes,

[0064] A spherical shell 251, the inside of the spherical shell 251 is a hollow structure, and on both sides of the inner cavity of the spherical shell 251, butt tubes 252 are symmetrically fixedly connected through through ports, and the outer surface of the spherical shell 251 is rotationally connected to the outer surface of the outer rotating rod shell 21 through a spherical embedding groove;

[0065] An elastic connecting tube 253, one end of the elastic connecting tube 253 is communicated with the inside of the spherical shell 251 through the butt tube 252, the other end of the elastic connecting tube 253 is communicated with the inside of the hollow inner cylinder 22 through an interface, and the part where the elastic connecting tube 253 is connected to the butt tube 252 is made of elastic rubber and can undergo bending deformation;

[0066] A filtering nozzle 254, the inner wall of the filtering nozzle 254 is sleeved with one end of the spherical shell 251 far from the elastic connecting tube 253 through the butt tube 252, and a filter element is arranged inside the filtering nozzle 254, which can simply filter the passing gas and prevent external objects from entering the inside of the spherical shell 251.

[0067] The flow guiding component 3 includes,

[0068] A side-position cylinder shell 31, on the side of the inner wall of the side-position cylinder shell 31 close to the cylinder component 1, it is in rolling connection with the outer surface of the outer rotating rod shell 21;

[0069] A pressure pump 32, the outer surface of the pressure pump 32 is slidably connected to the axis of the inner wall of the side-position cylinder shell 31, and the top of the air outlet of the pressure pump 32 is inserted into one end of the hollow inner cylinder 22, and the pressure pump 32 can rotate relative to the hollow inner cylinder 22;

[0070] The horizontal slide rail 34 is arranged on the side of the inner wall of the side cylinder shell 31 away from the hollow inner cylinder 22. The inner wall of the horizontal slide rail 34 is slidably connected with a control clamping arm 33 through a rotating belt. The outer surface of the control clamping arm 33 is mutually extruded with the outer surface of the pressure pump 32. The horizontal slide rail 34 drives the rod part of the control clamping arm 33 to move left and right, thereby driving the pressure pump 32 to slide relative to the side cylinder shell 31;

[0071] The control motor 35 is fixedly installed on the side of the inner wall of the side cylinder shell 31 close to the cylinder body component 1. An extrusion roller 36 is arranged on the outer surface of the output shaft of the control motor 35. The outer surface of the extrusion roller 36 is mutually extruded with the outer surface of the outer rotating rod shell 21.

[0072] After fixing the device on the ground, open the cylinder body component 1, directly add flame retardant particles and grinding balls into the inside of the cylinder body component 1, and then close the cylinder body component 1 to complete the preliminary preparation work.

[0073] The suspension component 4 controls the cylinder body component 1 to rotate, so that the internal grinding balls fit the inner wall of the cylinder body component 1 and roll, and perform ball milling on the internal flame retardant. During the rotation of the cylinder body component 1, the controls on both sides drive the outer rotating rod shell 21 to rotate through the extrusion roller 36, so that the outer rotating rod shell 21 rotates synchronously, and can also rotate the outer rotating rod shell 21 relative to the cylinder body component 1 by reducing the speed.

[0074] During the rotation of the outer rotating rod shell 21, the pressure pumps 32 on both sides will inflate and pressurize the inside of the hollow inner cylinder 22. At this time, the internal pressure of the hollow inner cylinder 22 increases, and the special nozzle 25 arranged in the middle blows air into the inside of the cylinder body component 1. After the air flow enters the inside of the cylinder body component 1 through the elastic connecting pipe 253, the spherical shell 251 and the filtering nozzle 254, it blows the flame retardant particles that are performing ball milling work inside the cylinder body component 1, so as to disperse the flame retardant that has aggregated due to the ball milling work. When the internal air blowing component 2 is working, the horizontal slide rails 34 on both sides drive their respective pressure pumps 32 to alternately move left and right through the control clamping arms 33. At this time, the hollow inner cylinder 22 drives the elastic connecting pipe 253 of the special nozzle 25 to slide left and right relative to the outer rotating rod shell 21. The sliding friction resistance received by the hollow inner cylinder 22 is reduced by the embedded ball 24. Since the bottom end of the elastic connecting pipe 253 is pulled by the hollow inner cylinder 22 and will undergo a bending deformation, at this time, the elastic connecting pipe 253 will drive the spherical shell 251 to twist relative to the outer rotating rod shell 21 through the connecting pipe 252, and further cause the nozzle angle of the filtering nozzle 254 to deflect. Therefore, when the special nozzle 25 is performing the air blowing work, the air blowing direction of the special nozzle 25 is not fixed, and since the special nozzle 25 can be deflected, there will be no air blowing dead angle.

[0075] After ball milling is completed, the horizontal slide rail 34 resets the control clamping arm 33. As Figure 6 shown, at this time, the hollow inner cylinder 22 returns to its initial position again. The elastic connecting pipe 253 remains in a straight tube shape and is not subjected to tensile force, and the spherical shell 251 also automatically resets.

[0076] Example 2, please refer to Figures 1 - 10 . The present invention provides a technical solution: on the basis of Example 1, the suspension member 4 includes,

[0077] a fixed base 41, the bottom of the fixed base 41 is installed on the ground;

[0078] a control outer sleeve 43, the bottom of the control outer sleeve 43 is installed on the top of the fixed base 41, and control rotating wheels 44 are uniformly arranged on the inner wall of the control outer sleeve 43. The inner wall of the control outer sleeve 43 is in rolling connection with the outer surface of the cylinder member 1 through the control rotating wheels 44;

[0079] a side-position clamping frame 42, the bottom of the side-position clamping frame 42 is installed on the side of the fixed base 41, and the inner wall of the side-position clamping frame 42 is sleeved with the outer surface of the side-position cylinder shell 31.

[0080] The cylinder member 1 includes,

[0081] a receiving cylinder 11, a discharge groove 12 is opened at the top of the inner cavity of the receiving cylinder 11;

[0082] a rotating cover 13, one end of the rotating cover 13 is rotatably connected to the inner cavity of the receiving cylinder 11 through the discharge groove 12;

[0083] side vibration members 14, the number of the side vibration members 14 is two, which are installed on the inner wall of the receiving cylinder 11 to vibrate the inner wall of the receiving cylinder 11.

[0084] The side vibration member 14 includes,

[0085] a wall-attached shell 141, the outer surface of the wall-attached shell 141 is fixedly connected to one side of the inner wall of the receiving cylinder 11, and impact blocks 142 are uniformly arranged on the inner wall of the wall-attached shell 141. The impact blocks 142 are made of metal steel, and the wall-attached shell 141 is a metal shell. Its cross-section is as Figure 9 shown, and the impact blocks 142 are arranged in the depressions on the inner wall of the wall-attached shell 141;

[0086] a rotating motor 144, a rotating cam 143 is installed on the outer surface of the output shaft of the rotating motor 144, and the outer surface of the rotating cam 143 is mutually pressed against the outer surface of the impact block 142. The outer surface of the rotating motor 144 is fixedly connected to the inner wall of the wall-attached shell 141 through a welding rod. When the rotating cam 143 rotates, it will periodically knock on the impact block 142, so that the wall-attached shell 141 vibrates.

[0087] Under the rolling action of the control runner 44 inside the control jacket 43, the cylinder body component 1 rotates around its own axis along the inner wall of the control jacket 43. At this time, the side cylinder shell 31 also rotates around its own axis along the inner wall of the side bracket 42. Since the side bracket 42 restricts the side cylinder shell 31 on both sides, the cylinder body component 1 will not shake during rotation.

[0088] After the flame retardant in the accommodating cylinder 11 is ball-milled into refined particles, the discharging chute 12 is rotated to the directly above position, and the rotating cover 13 is opened. A filter screen is installed at the discharging chute 12. Then, the accommodating cylinder 11 is rotated half a turn. At this time, the flame retardant particles inside the accommodating cylinder 11 fall through the filter screen into the lower receiving container for collection. The grinding balls inside the accommodating cylinder 11 are blocked by the filter screen. The accommodating cylinder 11 makes a small amplitude reciprocating deflection under the action of the control runner 44, so as to accelerate the discharging work inside. After the discharging is completed, the discharging chute 12 is rotated to the directly above position again, the filter screen is taken out, the next batch of flame retardant particles to be ground is added, the rotating cover 13 is closed, and the above-mentioned ball-milling work is carried out in a cycle.

[0089] During the ball-milling work inside the accommodating cylinder 11, the rotating motors 144 inside the wall-attached shells 141 on both sides will control the rotating cams 143 to rotate continuously around their own axes. Thus, by means of the rotating cams 143 knocking on the impact blocks 142, the wall-attached shells 141 on the sides are continuously vibrated. As a result, the flame retardant gathered on both sides of the inner wall of the accommodating cylinder 11 is shaken loose and gathers towards the middle position of the accommodating cylinder 11, and then is blown away by the special nozzle 25.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
