Description

Technical Field

[0001] The invention relates to the technical field of sand mills, in particular to a high-efficiency sand mill for producing suspension agents. Background Art

[0002] The working principle of the sand mill is to use a material pump to input the solid-liquid mixture that has been pre-dispersed and wetted by the mixer into the cylinder. The material and the grinding media in the cylinder are stirred by the high-speed rotating disperser, so that the solid particles in the material and the grinding media produce stronger collision, friction and shearing effects with each other, so as to accelerate the grinding of particles and disperse aggregates. In the production process of suspension agents, it is necessary to obtain suspension agents that meet standard quality, which is inseparable from the grinding of suspension agent raw materials by sand mills.

[0003] According to the Chinese patent with the announcement number CN213000351U, a horizontal sand mill for suspending agent processing is disclosed. The utility model can make the main shaft of the sand mill work in the optimal working temperature range, and the utility model can also make the material temperature more uniform; According to the Chinese patent with the announcement number CN115350772B, a horizontal sand mill for producing pesticides is disclosed. The horizontal sand mill for producing pesticides can effectively solve the problem that in the prior art, most sand mills use the high-speed rotation of dispersing blades or rod pins to generate centrifugal force between ingredients and grinding media, thereby dispersing the ingredients of the pesticide suspension. However, since the particle size of the ingredients initially introduced is relatively large, the sand mill is not equipped with a pretreatment mechanism, and the centrifugal force generated by the rotation of the dispersing blades or rod pins is limited, so that the ingredients cannot be ground quickly, which greatly reduces the grinding efficiency of the grinding media and accelerates the wear and breakage of the grinding media. When the above technical solution is used, the raw materials are stirred and mixed in the barrel, and grinding is completed through the contact between the raw materials and the grinding medium. During the grinding process, the raw materials will accumulate in local positions, resulting in the inability to fully grind the raw materials, and the grinding and crushing efficiency of the suspension product is low.

[0007] Preferably, a guide rod with a polygonal column structure is fixed to one end of the push-pull rod away from the extrusion disk, and a return spring is sleeved on the outer side of the guide rod.

[0014] Preferably, a liquid storage tank is provided inside the machine base, and a discharge pipe communicating with the liquid storage tank is connected to one side of the machine base.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The high-efficiency sand mill used for the production of suspensions is provided with a quick-installation mechanism, a counter-grinding mechanism and a recoil disk linkage setting, so that the multiple quick-installation mechanisms with staggered distribution can install the counter-grinding mechanism in an equidistant and staggered manner. When the agitator shaft drives the grinding disk of the counter-grinding mechanism to rotate and grind the raw materials, the two adjacent grinding disks perform transverse counter-grinding grinding on the raw materials through intermittent flipping, and at the same time, the recoil disk is used to perform flow recoil on the transversely flowing raw materials, thereby ensuring that the mixed raw materials for producing the suspension are efficiently ground in the sand mill.

[0016] 1. The high-efficiency sand mill for the production of suspension concentrate uses a motor to drive multiple groups of grinding discs of the counter-grinding mechanism on the stirring shaft to shear and grind the mixed raw materials. The intermittent extrusion of the two extrusion discs can drive the grinding discs to intermittently push the mixed raw materials laterally when grinding the raw materials, so that the raw materials are laterally counter-balanced between the barrel and the conical head. When the two adjacent grinding discs are adjusted from a state of being away from each other to a state of being close to each other, the two adjacent grinding discs will squeeze the mixed raw materials between them to rotate. When the two adjacent grinding discs are adjusted from a state of being close to each other to a state of being away from each other, the two edges of the two grinding discs will concentrate on grinding the mixed raw materials, thereby ensuring that the sand mill can achieve efficient grinding of the suspension concentrate raw materials and conveniently accelerate the grinding processing speed of the suspension concentrate products; 2. The high-efficiency sand mill used for the production of suspension can make the mixed raw materials flow in a circle between two adjacent recoil discs when the stirring shaft rotates rapidly, and grind the mixed raw materials through the grinding protrusions. At the same time, the rotation of the grinding protrusions can make the raw materials between the two recoil discs flow toward the barrel at an inclined angle. Therefore, when the counter-grinding mechanism pushes the ground mixed raw materials horizontally to the conical head position, the recoil disc can make the raw materials tilted in the opposite direction and thrown to the barrel position, ensuring that the mixed raw materials can achieve reciprocating flow grinding in the sand mill.

The grinding disc 601 is a fan-shaped structure, and a U-shaped interface is provided on the inner side of the grinding disc 601. A drainage groove is provided on the surface of the grinding disc 601 close to the cutting edge 602. When the grinding disc 601 rotates, the raw material particles for producing the suspension are sheared by the cutting edge 602, and the flow direction of the raw material grinding can be changed by the drainage groove; the surface of the grinding disc 601 is provided with a through hole 603, and the gap between the two adjacent grinding discs 601 A support arm 604 is movably connected between the support arm 604 and the support arm 604 is a "V"-shaped structure. A traction rod 605 is movably connected to the hinged end in the middle of the support arm 604. The traction rod 605 is slidably inserted in the slide groove 505, and one end of the traction rod 605 inserted into the slide groove 505 is connected to a guide wheel. A push-pull rod 606 is slidably connected to the inside of the stirring shaft 201. A convex ring 607 that abuts against the guide wheel is equidistantly fixed to the outer side of the push-pull rod 606. An extrusion disk 8 is fixed to one end of the push-pull rod 606 and the inner wall of the baffle plate 402. The surface of the extrusion disk 8 is symmetrically provided with arc-shaped protrusions. Recoil disks 9 are sleeved on both ends of the stirring shaft 201 close to the conical head 4. A guide rod 608 with a multi-prism structure is fixed to one end of the push-pull rod 606 away from the extrusion plate 8, and a return spring 609 is sleeved on the outer side of the guide rod 608. A reserved groove is provided on the inner end of the stirring shaft 201 to prevent the guide rod 608 from sliding. A motor 202 is installed on the lower side of the driving seat 2, and a transmission device connecting the motor 202 and the stirring shaft 201 is arranged on the inner side of the driving seat 2. The transmission device adopts one of synchronous belt drive and chain drive. Both ends of the stirring shaft 201 are movably connected to the conical head 4 through sealed bearings.

[0021] In the specific implementation, first, the raw materials for producing the suspension are introduced through the feed port 301 at the top of the barrel 3, and the grinding materials are introduced into the two conical heads 4 from the grinding medium feeding pipe 401; then, the motor 202 is started, so that the motor 202 drives the stirring shaft 201 to rotate through the transmission device in the driving seat 2, so that the stirring shaft 201 can drive the grinding disc 601 outside the quick-loading mechanism 5 to rotate when rotating, so that the mixed raw materials flow from the gaps on both sides of the grinding disc 601, and because the grinding disc 601 can shear and stir the mixed raw materials through the cutting edge 602 on the surface when rotating, the raw materials collide with the grinding disc 601 to complete the crushing and grinding; When the stirring shaft 201 rotates, the push-pull rod 606 will be driven to rotate through the internal reserved groove and the guide rod 608 of the multi-prism structure. When the push-pull rod 606 rotates, the extrusion disk 8 at its end will be driven to rotate. Since the baffle plate 402 is installed on the outside of the conical head 4, the extrusion disk 8 inside the baffle plate 402 cannot rotate. Therefore, when the push-pull rod 606 rotates, the extrusion disk 8 at its end and the extrusion disk 8 inside the baffle plate 402 will produce relative rotational movement. When the two extrusion disks 8 are squeezed against each other through the arc-shaped protrusions, the push-pull rod 606 will be pushed into the inside of the stirring shaft 201 and compress the reset spring 609. At the same time, the push-pull rod 606 will squeeze the guide wheel at one end of the traction rod 605 through the outer convex ring 607. The traction rod 605 is pushed outward along the slide groove 505 of the driving sleeve 501, so that the traction rod 605 can push the "V"-shaped support arm 604 to open the angle, and then the support arm 604 will drive the two adjacent grinding discs 601 to rotate around the connecting piece 504; because the two adjacent connecting pieces 504 are meshed by gears, it can be ensured that the two adjacent grinding discs 601 can be synchronously moved away. Therefore, when the two extrusion discs 8 are squeezed against each other through the arc-shaped protrusions, the support arm 604 will push the two adjacent grinding discs 601 to quickly flip and move away laterally, so that the grinding discs 601 can intermittently push the mixed raw materials laterally while rotating in a circle to grind the raw materials, so that the raw materials are laterally offset between the barrel 3 and the conical head 4; When the arc-shaped protrusions of the two extrusion disks 8 are misaligned and separated, the push-pull rod 606 drives the protruding ring 607 away from the guide wheel at one end of the traction rod 605 through the elastic squeezing of the reset spring 609. Under the action of the centrifugal force generated by the rotation of the grinding disk 601, the two adjacent grinding disks 601 will move closer to each other, thereby reducing the angle of the support arm 604 of the "V"-shaped structure, and the two adjacent grinding disks 601 will be reset to their original state.

[0022] See also Figure 2-Figure 8 The outer side of the stirring shaft 201 is composed of an arc surface and a plane, and the planes on the outer side of the stirring shaft 201 are symmetrically distributed, and plug interfaces communicating with the slide groove 505 are opened on the two side planes of the stirring shaft 201, and the central opening of the driving sleeve 501 is matched with the stirring shaft 201; The two sides of the driving sleeve 501 are symmetrically and slidably connected with the mounting seats 502, and the driving sleeve 501 and the mounting seats 502 are fastened by bolts. The side of the mounting seat 502 away from the driving sleeve 501 is embedded with a limiting shell 503, and the inner side of the limiting shell 503 is movably connected with two connecting members 504. The connecting member 504 is composed of a gear and a driving shaft fixed to the center of the gear, and the gears of two adjacent connecting members 504 are meshed with each other, and the driving shaft of the connecting member 504 extends out of the limiting shell 503 and is fixed to the U-shaped interface end of the grinding disc 601. Two limiting rings 7 for clamping the quick-loading mechanism 5 are also installed on the stirring shaft 201. By installing two limiting rings 7 on the stirring shaft 201, the installation of multiple quick-loading mechanisms 5 can be limited to prevent the quick-loading mechanism 5 from shifting.

[0023] In specific implementation, when assembling the counter-grinding mechanism 6 to the stirring shaft 201, first, the driving sleeve 501 with the slide groove 505 is staggered and sleeved on the outside of the stirring shaft 201, and the slide groove 505 of each driving sleeve 501 corresponds to the plug-in interface of the outer plane of the stirring shaft 201; then, the connecting piece 504 is docked to the limiting shell 503, and the limiting shell 503 is embedded and installed in the mounting seat 502, and then the driving shaft of the connecting piece 504 is fixed to the U-shaped interface of the grinding disc 601; finally, the mounting seat 502 is symmetrically slid and placed on both sides of the driving sleeve 501, and the driving sleeve 501 and the mounting seat 502 are fastened with bolts, so that the counter-grinding mechanism 6 can be quickly installed through the quick-installation mechanism 5; When the driving sleeve 501 with the slide groove 505 is offsetly sleeved on the outer side of the stirring shaft 201, the grinding discs 601 of the counter-grinding mechanism 6 will be equidistantly offset on the stirring shaft 201. When two adjacent grinding discs 601 are in a close state, the stirring shaft 201 drives the equidistantly offset grinding discs 601 to rotate, so as to grind the mixed raw materials concentrated in the barrel 3 at high speed. When the two adjacent grinding discs 601 are in a flipped away state, the equidistantly offset grinding discs 601 will push the mixed raw materials laterally to produce a counter-collision. At the same time, a through hole 603 is provided on the surface of the grinding disc 601, so that the counter-flowing mixed raw materials can produce a long-distance lateral movement. Therefore, the grinding intensity of the mixed raw materials can be enhanced by the grinding medium and the grinding disc 601. When two adjacent grinding discs 601 are adjusted from a state of being away from each other to a state of being close to each other, the two adjacent grinding discs 601 will squeeze the mixed raw materials between them to rotate, and the ground and crushed raw materials will be discharged to both sides from the through holes 603 on the surfaces of the grinding discs 601; when two adjacent grinding discs 601 are adjusted from a state of being close to each other to a state of being away from each other, the two interval grinding discs 601 will drive the cutting edges 602 to flip and approach each other, at this time, the cutting edges 602 on both sides of the two grinding discs 601 will concentrate on grinding the mixed raw materials, and at the same time, the ground and crushed raw materials will be discharged to both sides from the through holes 603 on the surfaces of the grinding discs 601, thereby ensuring that the sand mill can realize efficient grinding of the suspension raw materials, and conveniently accelerate the grinding processing speed of the suspension products.

[0024] See also Figure 2-Figure 4 as well as Figure 14-16 At least two recoil discs 9 are provided near the inner side of the conical head 4, an elliptical opening is provided in the middle of the recoil disc 9, and the two sides of the recoil disc 9 near the elliptical opening are movably connected to the stirring shaft 201 through a polished rod screw 901, and a wear-increasing protrusion 902 is provided on the inner wall surface of the recoil disc 9.

[0025] In specific implementation, since the recoil disk 9 is movably connected to the stirring shaft 201 through the elliptical smooth rod screw 901, when the stirring shaft 201 rotates slowly, the centrifugal force of the recoil disk 9 is insufficient, which will cause the recoil disk 9 to follow the rotation of the stirring shaft 201 to achieve flipping and swinging, so that the mixed raw materials can be randomly swung from the conical head 4 to the barrel 3. When the stirring shaft 201 rotates rapidly, the centrifugal force of the recoil disk 9 is sufficient to cause the recoil disk 9 to follow the rotation of the stirring shaft 201 to achieve stable rotation, so that the mixed raw materials can generate a circumferential flow between two adjacent recoil disks 9, and the mixed raw materials are ground by the grinding protrusion 902. At the same time, the rotation of the grinding protrusion 902 can make the raw materials between the two recoil disks 9 flow toward the barrel 3 at an inclined angle. Therefore, when the counter-grinding mechanism 6 pushes the ground mixed raw materials horizontally to the position of the conical head 4, the action of the recoil disk 9 can make the raw materials be reversely tilted and swung to the position of the barrel 3, ensuring that the mixed raw materials are reciprocatingly flowed and ground in the sand mill.

[0026] See also Figure 1 and Figure 2 The bottom of the barrel 3 is connected with a discharge valve pipe 102, and a control valve is installed on the discharge valve pipe 102; a liquid storage tank 101 is arranged inside the machine base 1, and a discharge pipe connected with the liquid storage tank 101 is connected to one side of the machine base 1. When the mixed raw materials are ground to meet the quality requirements of the suspension product, the control valve on the discharge valve pipe 102 is opened, so that the product is transported to the liquid storage tank 101 along the discharge valve pipe 102, which is convenient for the liquid storage tank 101 to temporarily store the suspension, and the suspension is conveniently discharged through the discharge pipe on one side of the liquid storage tank 101.

[0027] In summary, the raw materials for producing the suspension are introduced along the feed port 301 at the top of the barrel 3, and the grinding material is introduced into the two conical heads 4 from the grinding medium feeding pipe 401, and the motor 202 is started to drive the stirring shaft 201 and the hedge grinding mechanism 6 to rotate, so that the mixed raw materials flow from the gaps on both sides of the grinding disk 601, and the mixed raw materials are sheared and stirred by the cutting edge 602 on the surface of the grinding disk 601, so that the raw materials collide with the grinding disk 601 to complete the crushing and grinding. When the mixed raw materials are ground to meet the quality requirements of the suspension product, the control valve on the discharge valve pipe 102 is opened, so that the product is transported and stored in the liquid storage tank 101 along the discharge valve pipe 102.
