DETAILED DESCRIPTION

[0024] 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.

[0025] The utility model provides technical schemes: as Figure 1 、 Figure 2 and Figure 3 indicate, in the embodiment, a discharging and scattering mechanism for superfine vertical mill, including the discharge pipe 1, the inside installation of discharge pipe 1 has scattering subassembly 4, and the top of discharge pipe 1 circumferential inner wall is provided with mounting ring, and the mounting ring top is placed with filter screen 2, and filter screen 2 is connected with mounting ring through bolt and is dismantled, and the nozzle 405 is set below filter screen 2, and scattering subassembly 4 includes the air inlet pipe 401 fixedly inserted in the discharge pipe 1 circumferential inner wall, and the one end fixed sleeve of air inlet pipe 401 inside discharge pipe 1 is provided with swivel joint 402, and the swivel joint 402 rotating end inside fixedly inserted has installation pipe 403, and the top one end fixed sleeve of installation pipe 403 is provided with air outlet pipe 404, and air outlet pipe 404 is horizontally arranged, and the top outer wall of air outlet pipe 404 is provided with multiple equidistance distribution nozzles 405, and multiple nozzles 405 are all arranged in inclined upward.

[0026] As Figure 4 indicate, the top fixed sleeve of air inlet pipe 401 circumferential outer wall is provided with connecting plate 409, and the top outer wall of connecting plate 409 is fixedly installed with motor 407, and the coaxial fixed gear 408 of motor 407 output end is fixedly inserted with gear ring 406 on the bottom of installation pipe 403 circumferential outer wall, and gear 408 is engaged with gear ring 406.

[0027] The material after grinding is blown up and moves upward under the action of wind, then contacts the back of filter screen 2, and the unqualified material is intercepted, thereby gradually forming material accumulation, and the external fan is started, and the airflow enters swivel joint 402 through air inlet pipe 401, then enters the inside of air outlet pipe 404 through installation pipe 403, and finally is sprayed outward through multiple nozzles 405, since the nozzles 405 are arranged in inclined, the airflow generated thereby can exert a horizontal thrust in addition to the vertical upward thrust, thereby greatly improving the scattering effect, and the motor 407 in the connecting plate 409 is started, and the output end drives gear 408 to rotate, and gear 408 can drive installation pipe 403 to rotate through the engagement of gear ring 406, and then air outlet pipe 404 will perform circumferential motion, thereby greatly improving the scattering effect.

[0028] As Figure 1 and Figure 2 indicate, the outside of discharge pipe 1 is provided with sealing assembly 5, and the bottom of discharge pipe 1 circumferential outer wall is provided with through groove 3, and sealing assembly 5 is located at the position of one side of through groove 3.

[0029] The closed assembly 5 comprises a mounting frame 501 fixedly connected to the middle part of the outer wall of the discharge pipe 1, two horizontally arranged limiting rods 503 fixedly connected to the outer wall of one side of the mounting frame 501, a moving frame 504 slidably sleeved with the outer part of the two limiting rods 503, a vertical sealing plate 505 fixedly connected to the outer wall of one side of the moving frame 504, the sealing plate 505 being capable of sealing the through groove 3, a lead screw 502 rotatably connected to the middle part of the outer wall of one side of the mounting frame 501, and the lead screw 502 being in transmission cooperation with the moving frame 504.

[0030] With the increase of the use time, if the components inside the discharge pipe 1 need to be overhauled, the lead screw 502 is only rotated by the handle, and since the sealing plate 505 is small in size, the weight of the sealing plate 505 will not press the lead screw 502 to bend, and the moving frame 504 will move away from the discharge pipe 1 along the limiting rods 503 under the cooperation of the lead screw 502 and the two limiting rods 503, and then the sealing plate 505 will be driven by the moving frame 504 to move away from the through groove 3, so that the operator can observe the inside of the discharge pipe 1 and operate through the through groove 3.

[0031] As shown in Figure 4 The protective cover 410 is detachably connected with the connecting plate 409 by bolts, and the protective cover 410 can completely surround the gear 408 and the tooth ring 406, so that the installation pipe 403 can normally rotate, and dust cannot be between the gear 408 and the tooth ring 406 to cause transmission obstacles.

[0032] As shown in Figure 2 The reinforcing frame 411 is detachably connected with the protective cover 410 by bolts, and the state of the protective cover 410 will be more stable under the action of the reinforcing frame 411, so as to ensure that the states of the installation pipe 403 and the air outlet pipe 404 are stable enough.

[0033] The utility model provides a kind of discharging and scattering mechanism for superfine vertical mill, and specific working principle is as follows:

[0034] When the device works, the ground material is blown up and moves upward under the action of wind force, then contacts the back of filter screen 2, and unqualified material is intercepted, thereby gradually forming material accumulation,

[0035] The external fan is started, air flows into the rotary joint 402 through the air inlet pipe 401, then enters the air outlet pipe 404 through the installation pipe 403, and finally is sprayed outward through the multiple spray heads 405. Since the spray heads 405 are arranged obliquely, the air flow generated thereby can exert a horizontal thrust in addition to the vertical upward thrust, thereby greatly improving the scattering effect. Meanwhile, the motor 407 inside the connecting plate 409 is started, the output end of the motor 407 drives the gear 408 to rotate, the gear 408 drives the installation pipe 403 to rotate through the tooth ring 406 engaged with the gear 408, and the air outlet pipe 404 then performs a circular motion, thereby greatly improving the scattering effect.

[0036] With the increase of the use time, if it is necessary to overhaul the components inside the discharge pipe 1, the handle is used to drive the screw rod 502 to rotate. Since the individual sealing plate 505 is small, the weight of the sealing plate 505 will not press the screw rod 502 to bend. The moving frame 504 is driven by the screw rod 502 and cooperates with the two limiting rods 503, so as to move away from the discharge pipe 1 along the limiting rods 503. The sealing plate 505 is driven by the moving frame 504 to move away from the through slot 3. The operator can observe the internal condition of the discharge pipe 1 through the through slot 3 and perform the operation.

[0037] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
