Detailed Description

Specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a fire retardant crushing device comprises a housing 1, a rotatable barrel net rack 2 is arranged in the housing 1, the two ends of the cylinder net rack 2 are sleeved on a left supporting body 3 and a right supporting body 4 which are fixedly connected with the shell 1, the cylinder net rack 2 is connected with a first motor 5 in a transmission way, the inner wall of the cylinder net rack 2 is provided with a strip-shaped clapboard 6 which extends axially, a pair of crushing rollers 7 are arranged in the cylinder net rack 2, the crushing rollers 7 are supported by a crushing rotating shaft 8, one end of the crushing rotating shaft 8 is rotatably connected to the right supporting body 4, the other end of the crushing rotating shaft penetrates through the left supporting body 3 and the shell 1 to be connected with a second motor 9, be provided with feeder hopper 10 on the shell 1, the discharge end 11 of feeder hopper 10 passes stretch into in the left branch body 3

barrel rack

2, 1 bottom of shell is provided with discharge gate 12.

Further, the top of smashing roller 7 is followed 2 axial of barrel rack is provided with the dispersion subassembly 13 that is used for conveying the fire retardant, dispersion subassembly 13 includes top open-ended silo 14, the both ends of silo 14 respectively with left branch body 3 with 4 fixed connection of right branch body, be provided with a plurality of blanking mouths 15 of arranging along 14 axial direction of silo on the 14 lateral walls of silo, be provided with first pivot 16 in the silo 14 and coil and be in helical blade 17 in the first pivot 16, the left end of first pivot 16 passes left branch body 3 with shell 1 is connected with third motor 18, the right-hand member with 4 rotatable coupling of right branch body. Adopt this kind of structure, fall into silo 14 when the fire retardant gets into barrel rack 2 in, pass through the rotation of coiling helical blade 17 on first pivot 16, make the fire retardant remove to blanking mouth 15 and fall in silo 14, pile up the left end of barrel rack 2 when having avoided the fire retardant to get into in barrel rack 2. Furthermore, the discharge end 11 extends into the trough 14, so that the flame retardant can completely enter the trough 14 for dispersion treatment, and the phenomenon that the flame retardant rebounds the trough 14 due to the rotation of the spiral blade 17 when falling from a high place is avoided. Furthermore, the trough 14 is U-shaped, and with the structure, the fire retardant is accumulated at the bottom of the U-shaped trough under the action of the gravity of the fire retardant, and the bottom of the U-shaped trough 14 is similar to the shape of the spiral blade 17, so that the fire retardant can be moved to the maximum extent when the spiral blade 17 pushes the fire retardant, and the fire retardant is prevented from scattering at the position where the spiral blade 17 cannot act. Furthermore, the plurality of blanking ports 15 are distributed in a step shape. By adopting the structure, when the flame retardant is pushed in the trough 14 and passes through the stepped blanking port 15, the flame retardant can be more uniformly dispersed and dropped on the crushing roller 7 for crushing, and the crushing efficiency of the flame retardant is improved.

Further, fixedly connected with brush 19 on the 1 roof of shell, and brush 19 and the contact of barrel rack 2 adopt this kind of structure, when barrel rack 2 rotated, fix brush 19 and the contact of pivoted barrel rack 2 on shell 1, brush 19 clears up barrel rack 2, makes the fire retardant of jam on barrel rack 2 drop to further smash in barrel rack 2, can prevent that the fire retardant from blockking up barrel rack 2 and causing the condition of unable screening fire retardant.

Furthermore, the circumferential convex teeth 20 on the outer wall of the cylinder net rack 2 are engaged with the gear body 21 connected to the rotating shaft of the first motor 5, and the transmission mode can also adopt other transmission structures, such as a worm and turbine transmission mode.

Further, the bottom surface of the housing 1 is inclined, and the discharge hole 12 is arranged at the lower end of the inclined surface. When the flame retardant which reaches the use standard falls on the bottom of the shell 1, the bottom surface is arranged to be an inclined structure, the flame retardant can slide along with the inclined surface under the action of the gravity of the flame retardant, and the discharge port 12 is arranged at the lower end of the inclined surface, so that the flame retardant can be discharged conveniently.

Further, the strip-shaped division bars are obliquely arranged. Adopt this kind of mechanism, the slope of bar baffle 6 sets up, forms between bar baffle 6 and the barrel rack 2 and holds putting the material space of fire retardant, when 2 circumferential direction of barrel rack, puts the material space and enables a large amount of fire retardants and falls down when the highest point along with 2 circumferential direction of barrel rack, has improved the crushing efficiency of fire retardant.

Further, the cylinder net rack 2 is connected with the left support body 3 and the right support body 4 through bearings, so that the friction force of the cylinder net rack 2 relative to the rotation of the support bodies is reduced when the structure is adopted, and the rotation is smoother.

Further, be provided with crushing blade on 2 inner walls of barrel rack, when the fire retardant was when 2 rotations of barrel rack, crushing blade on 2 inner walls of barrel rack also can smash the fire retardant, had improved the crushing efficiency of fire retardant.

By adopting the scheme, the fire retardant enters the left end of the barrel net rack 2 and falls into the trough 14 of the dispersion component 13 through the feeding port, the fire retardant is pushed to the right end along with the rotation of the helical blade 17 coiled on the first rotating shaft 16, when the fire retardant passes through the stepped blanking port 15 and falls onto the crushing roller 7 through the blanking port 15, the second motor 9 drives the crushing rotating shaft 8 to rotate, the crushing rotating shaft 8 drives the crushing roller 7 to rotate, the fire retardant is crushed through the crushing roller 7, the fire retardant which reaches the use standard falls onto the bottom of the shell 1 through the screening of the barrel net rack 2, the fire retardant which does not reach the use standard is left in the barrel net rack 2, along with the rotation of the barrel net rack 2, the fire retardant moves to the highest position under the action of the strip-shaped partition plate 6 and falls into the trough 14 of the dispersion component 13, and continues to uniformly fall onto the crushing roller 7 through the blanking port 15 along with the pushing of the rotating blade, the process is repeated until all the fire retardants in the barrel net rack 2 reach the use standard. In this scheme, not only can circulate and smash the fire retardant, can also add when kibbling needs kibbling fire retardant to the barrel rack 2 in, the volume that makes the interior kibbling fire retardant of needs of barrel rack 2 tends to stably, can not only make the crushing more thorough of fire retardant this moment, the size is more even, and need not artificially observe again and filter the fire retardant that does not reach standard and smash once more, the crushing state that can also make reducing mechanism remains stable, the rate of utilization of improving reducing mechanism.
