A plurality of first air ducts with inlets on the side wall of the cylindrical grinding wheel are uniformly arranged in the cylindrical grinding wheel. The output shaft and the cylindrical grinding wheel are driven to rotate by the rotating motor. The sand and stone material falling from the circular mounting plate falls onto the upper surface of the sand table and slides down between the cylindrical grinding wheel and the sand table. The relative motion between the outer side surface of the cylindrical grinding wheel and the inner side surface of the sand table drives the sandstone raw materials to rub in the horizontal direction each other in the falling process, and the sandstone raw materials rub against the outer side surface of the cylindrical grinding wheel and the inner side surface of the sand table, so that the sharp parts on the surface of the sandstone raw materials are rubbed.

The periodic communication of the vent hole and the third vent passage is realized through the rotation of the mounting column, so that periodic air pressure pulses are generated in the first vent passage, the second vent passage, the third vent passage, the fourth vent passage and the vent hole. When air vent and third air flue intercommunication, the separation blade is moved to the inboard under the effect of gas pressure to drive push rod and steel ball and move to the inboard, the flexure strip produces deformation to the inboard. When the vent hole and the third vent passage are separated from a communicated state, the elastic sheet recovers the initial state, the elastic sheet generates outward deformation under the action of inertia force after recovering the initial state, and drives the push rod, the blocking piece and the steel ball to move outwards for a certain distance, the steel ball moves to the outer sides of the inlets of the first vent passage and the second vent passage and collides with the sandstone raw material, and the sandstone raw material is overturned after receiving the collision force, so that the surface of the sandstone raw material between the outer side surface of the cylindrical grinding wheel and the inner side surface of the sand table can be ground flat; the sandstone raw material surface between erection column and the heating cylinder everywhere can both produce the contact with the heating cylinder, has improved the effect of grinding and flat and drying.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in figures 1 to 8, the embodiment provides a dry-mixed mortar grit raw material processing apparatus, dries to the grit raw material, including the cylindrical sealed section of thick bamboo 1, the vertical fixed mounting in sealed section of thick bamboo 1 bottom plate below has supporting leg 2. A rotating motor 3 is vertically and fixedly installed on the top plate of the sealing barrel 1 through a motor base, and an output shaft 4 of the rotating motor 3 penetrates through the top plate of the sealing barrel 1 and extends into the sealing barrel 1. An annular feed inlet 5 is arranged on a top plate of the sealing barrel 1 around the rotating motor 3, and an annular first material baffle 6 is arranged at the edge of the feed inlet 5 above the top plate. The sealing cylinder 1 is internally provided with a dispersing mechanism 7, a grinding mechanism 8 and a drying mechanism 9 from top to bottom in sequence. The cleaned sand and stone raw material is fed into the sealing cylinder 1 through the feeding port 5.
Horizontal fixed mounting of dispersion mechanism 7 is in the circular mounting disc 71 on output shaft 4, evenly sets up the logical groove that runs through from top to bottom of a plurality of on the circular mounting disc 71, leads to the inslot and radially rotates along circular mounting disc 71 and installs pivot 72, follows the even fixed mounting in its circumference in pivot 72 a plurality of and lead to groove edge complex dispersion board 73. The outer end of the rotating shaft 72 is fixedly provided with a bevel gear 74, and the inner side wall of the sealing cylinder 1 is horizontally and fixedly provided with a bevel gear ring 75 which is meshed with the bevel gear 74. The rotating motor 3 drives the output shaft 4, the circular mounting plate 71, the rotating shaft 72 and the bevel gear 74 to rotate, and the bevel gear 74 and the bevel gear ring 75 are in a mutually meshed state, so that the rotating shaft 72 and the dispersion plate 73 are driven to rotate by the bevel gear 74 while the bevel gear 74 rotates along with the circular mounting plate 71. The sandstone raw material entering the sealing cylinder 1 falls onto the circular mounting disc 71, is scattered by the dispersion plate 73 and then passes through the through groove to fall below the circular mounting disc 71. The dispersing mechanism 7 further includes an annular second retainer plate 76 and balls 77. The second retainer plate 76 is vertically and fixedly arranged at the edge of the upper surface of the circular mounting disc 71, and a ball 77 which is in rolling fit with the top plate of the sealing cylinder 1 is rotatably arranged at the top of the second retainer plate 76. In the rotating process of the circular mounting disc 71, the balls 77 abut against the lower surface of the top plate of the sealing barrel 1 to roll, and the second baffle plate 76 avoids the sandstone raw materials from falling from the edge of the circular mounting disc 71 under the action of centrifugal force, so that the sandstone raw materials are ensured to fall after being scattered after entering the through groove.
The grinding mechanism 8 comprises a cylindrical grinding wheel 81 horizontally and fixedly arranged on the output shaft 4, and an annular sand table 82 with the upper surface inclined towards the center is arranged on the inner side wall of the sealing cylinder 1. The outer side surface of the cylindrical grinding wheel 81 is in sliding fit with the inner side surface of the sand table 82. A plurality of first air ducts 83 with inlets on the side wall of the cylindrical grinding wheel 81 are uniformly arranged in the cylindrical grinding wheel 81. The output shaft 4 and the cylindrical grinding wheel 81 are driven to rotate by the rotating motor 3. The sand raw material falling from the circular mounting plate 71 falls onto the upper surface of the sand table 82 and slides down between the cylindrical grinding wheel 81 and the sand table 82. The relative motion between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82 drives the sandstone raw materials to generate friction in the horizontal direction in the falling process, and the sandstone raw materials also generate friction with the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82, so that the sharp parts on the surface of the sandstone raw materials are ground. The sand raw material falls down after being ground flat between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82. The bottom of the cylindrical grinding wheel 81 is fixedly provided with a guide cylinder 84, a guide rod 85 is horizontally and movably arranged in the guide cylinder 84, and the outer end of the guide rod 85 is bent upwards and rotatably provided with a rolling ball 86 matched with the lower surface of the sand table 82. A spring 87 is mounted between the inner end of the guide rod 85 and the inner end surface of the guide cylinder 84. The lower surface of the sand table 82 is in an arc shape which is bent upwards, and the sand table 82 is in up-and-down sliding fit with the inner side wall of the sealing cylinder 1. The output shaft 4 and the cylindrical grinding wheel 81 are driven to intermittently rotate by the rotating motor 3, so that the guide cylinder 84 is driven to intermittently rotate. During the period from the standstill to the maximum rotational speed of the guide cylinder 84, the guide rod 85 slides outward of the guide cylinder 84 by centrifugal force, and the spring 87 is stretched. In the process that the guide rod 85 slides outwards, the rolling ball 86 always props against the lower surface of the sand table 82 and pushes the sand table 82 to move upwards. In the process that the guide cylinder 84 is at a standstill from the maximum rotating speed, the centrifugal force applied to the guide rod 85 is gradually reduced, the guide rod 85 slides towards the inner side of the guide cylinder 84 to the initial position under the action of the tensile force of the spring 87, the rolling ball 86 always props against the lower surface of the sand table 82 in the process that the guide rod 85 slides towards the inner side, and the sand table 82 moves downwards to the initial position under the action of gravity. The sand table 82 moves up and down to move relative to the outer side of the cylindrical grinding wheel 81, so that vertical friction is applied to sand raw materials between the outer side of the cylindrical grinding wheel 81 and the inner side of the sand table 82, the sand raw materials continuously rotate under the combined action of horizontal friction and vertical friction, and the sharp part on the surface of the sand raw materials is fully ground. And threaded friction strips 88 which are matched with each other are fixedly arranged on the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82. The inlets of the first air channels 83 are spaced apart from top to bottom between the thread-like rubbing strips 88. After entering between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82, the sand raw material slides downwards along the thread-shaped friction strip 88 in a spiral manner, so that the time for applying horizontal and vertical friction force on the sand raw material by the thread-shaped friction strip 88 is prolonged, and the grinding effect is further improved.
In this embodiment, the diameter of the outlet of the third vent passage 96 is the same as the diameter of the vent hole 13, and the distances between the axis of the outlet of the third vent passage 96, the axis of the vent hole 13 and the axis of the mounting post 91 are equal to each other, and the distance is not less than the radius of the vent hole 13. The first air duct 83 and the second air duct 92 are provided with a push rod 16 therein via an elastic piece 15. A baffle 17 is fixedly arranged at the inner end of the push rod 16, and steel balls 18 positioned at inlets of the first air passage 83 and the second air passage 92 are fixedly arranged at the outer end of the push rod 16. The periodic communication between the vent hole 13 and the third vent passage 96 is realized by the rotation of the mounting post 91, so that periodic air pressure pulses are generated in the first vent passage 83, the second vent passage 92, the third vent passage 96, the fourth vent passage 11 and the vent hole 13. When the vent hole 13 is communicated with the third vent passage 96, the blocking piece 17 moves inwards under the action of gas pressure, so that the push rod 16 and the steel ball 18 are driven to move inwards, and the elastic piece 15 deforms inwards. When the vent hole 13 and the third vent passage 96 are disconnected from each other, the elastic sheet 15 recovers to the initial state, and generates outward deformation under the action of inertia force after recovering to the initial state, and drives the push rod 16, the baffle 17 and the steel ball 18 to move outwards for a certain distance, the steel ball 18 moves to the outer sides of the inlets of the first vent passage 83 and the second vent passage 92 to collide with the sandstone raw material, and the sandstone raw material is overturned after receiving the collision force, so that all parts on the surface of the sandstone raw material between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82 can be ground flat; the surfaces of the sandstone raw materials between the mounting column 91 and the heating cylinder 94 can be contacted with the heating cylinder 94, so that the effects of flattening and drying are improved.
The working process of the embodiment is as follows: the sand and stone raw material is fed into the sealing cylinder 1 from the feed port 5. The rotating motor 3 drives the output shaft 4, the circular mounting disc 71, the rotating shaft 72 and the bevel gear 74 to periodically and intermittently rotate, and the bevel gear 74 and the bevel gear ring 75 are in a mutually meshed state, so that the rotating shaft 72 and the dispersion plate 73 are driven to rotate by the bevel gear 74 while the bevel gear 74 rotates along with the circular mounting disc 71. The sandstone raw material entering the sealing cylinder 1 falls onto the circular mounting disc 71, is scattered by the dispersion plate 73 and then passes through the through groove to fall below the circular mounting disc 71. The sand raw material falling from the circular mounting plate 71 falls onto the upper surface of the sand table 82 and slides down between the cylindrical grinding wheel 81 and the sand table 82. The relative motion between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82 drives the sandstone raw materials to rub in the horizontal and vertical directions in the falling process, and the sandstone raw materials rub against the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82, so that the sharp parts on the surface of the sandstone raw materials are rubbed. The sand raw material falls down after being ground flat between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82. The sand material is milled and falls between the mounting post 91 and the heating cartridge 94. Relative movement between the mounting posts 91 and the heating cartridges 94 causes the sand material to roll as it falls in a spiral. The water on the surface of the sand raw material is evaporated under the heating action of the heating cylinder 94. Air is pumped from the vent hole 13, the third vent passage 96, the second vent passage 92, the fourth vent passage 11 and the first vent passage 83 through the air pump 12, and fine particles generated in the process of grinding the sand and stone raw materials between the outer side surface of the cylindrical grinding wheel 81 and the inner side surface of the sand table 82 are discharged after passing through the first vent passage 83, the fourth vent passage 11, the third vent passage 96 and the vent hole 13; high-temperature steam generated in the process of drying the sandstone raw material between the mounting column 91 and the heating cylinder 94 is discharged after passing through the second vent channel 92, the third vent channel 96 and the vent hole 13. The dried gravel raw material falls into the discharge port 14 after falling from between the mounting post 91 and the heating cylinder 94, and the material receiving equipment in the prior art is adopted to receive the material.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
