Description

Technical Field

[0001] The invention relates to the technical field of zinc stearate production, in particular to a pulverizing and grinding device for zinc stearate production. Background Art

[0002] As a chemical additive, zinc stearate is widely used in polyvinyl chloride heat stabilizers, plastic product lubricants, powder metallurgy release agents, rubber release agents, etc. In addition, zinc stearate can also be used as a polishing agent in coatings, especially as a polishing agent in coating primers, playing an irreplaceable role. At the same time, zinc stearate can also give the coating a certain thixotropy, improve the coating's anti-settling and filling properties. With the development of the industry and the improvement of people's environmental awareness, the process of improving powdered zinc stearate to granular has received more and more attention, and replacing powdered products is the trend and direction of future development; currently, a small number of granular zinc stearates have appeared on the market, but the production process is still not mature enough, and zinc stearate needs to be ground during its processing and production.

[0003] For example, a Chinese patent with the publication number "CN219051474U" discloses "a crushing and grinding device for zinc stearate production", whose main structure includes a working box, a cutting assembly is provided on the working box, and the cutting assembly includes cutting blades rotatably connected to both sides of the working box, and the two cutting blades are connected by a transmission unit, a grinding roller is provided inside the working box, a filter is provided inside the working box, and the filter is located below the grinding roller, and a servo motor is provided on the working box, and the servo motor drives the grinding roller to reciprocate through the reciprocating assembly, and the servo motor drives the grinding roller to move and drives the cutting assembly to rotate. The two cutting blades rotate in opposite directions under the transmission action of the transmission unit, and by providing the grinding roller, the raw materials after cutting can be ground, and the servo motor drives the grinding roller to move and drives the cutting assembly to rotate, which can reduce the use of the driving source, improve safety, and have a good use effect.

[0004] It can be known from the above description and the original technical solution that when the crushing and grinding device for zinc stearate production is actually working, the two cutting blades will first crush the zinc stearate raw material, and the crushed zinc stearate raw material will fall downward between the two grinding rollers, and then the two rotating grinding rollers will grind the fallen raw material. It has the following two defects: first, since the crushed zinc stearate raw material falls downward, part of the zinc stearate raw material will be separated from the grinding area of ​​the two grinding rollers due to collision and bounce, resulting in a relatively poor grinding effect; second, the crushed zinc stearate raw material is stuck between the two grinding rollers. Since the crushed raw material is relatively light in weight, and the grinding efficiency of the grinding roller is related to the downward pressure on the raw material, due to the strong mass, the pressure on the contact surface between the raw material and the grinding roller is relatively small, which will lead to slow grinding efficiency. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 and Figure 2A pulverizing and grinding device for zinc stearate production comprises a horizontal supporting base plate 1 with supporting legs 2 installed at the bottom, a driving motor 4 fixedly installed on the bottom surface of the horizontal supporting base plate 1 through a motor fixing shell 3, a vertical barrel body 6 fixedly installed on the upper end surface of the horizontal supporting base plate 1, a lower component movable cavity 7 arranged inside the vertical barrel body 6 and having an open bottom end, an upper component movable cavity 8 arranged at the top of the lower component movable cavity 7, a conical component installation cavity 9 arranged at the top of the upper component movable cavity 8, a raw material conveying hole 10 arranged at the top of the conical component installation cavity 9, and a raw material feeding hole 10 arranged at the top of the raw material conveying hole 10 and having an open top end. An inlet groove 11, a conical dividing plate 12 which is integrally arranged on the inner circumferential surface of the horizontal supporting substrate 1 and has a conical structure, and a raw material discharge port 13 which is arranged on the circumferential surface of the horizontal supporting substrate 1 and connected to the bottom area of ​​the conical dividing plate 12. In order to allow the powdered raw material to slide outward, it is necessary to make the upper diameter of the conical dividing plate 12 smaller than its lower diameter, and the lower diameter of the conical dividing plate 12 is consistent with the diameter of the movable cavity 7 of the lower component. It is used in conjunction with a hydraulic injection device, and the liquid circuit of the liquid injection device is connected to the No. 1 liquid flow hole 1515, and the zinc stearate raw material to be ground is put into the interior of the raw material input groove 11.

[0028] To achieve the crushing and grinding of zinc stearate raw materials, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up a raw material crushing and grinding mechanism 14, which is provided with a conical fixed cover 141 fixedly installed in the conical component installation cavity 9, a cutting blade 149 located in the raw material input groove 11 and capable of crushing the surrounding raw materials when rotating, a spiral blade 148 located in the raw material conveying hole 10 and capable of generating downward conveying pressure on the surrounding raw materials when rotating, and an inner conical rotating column 144 located in the conical fixed cover 141 and capable of grinding the raw materials located in the conical fixed cover 141 when rotating. The zinc stearate raw material is put into the raw material input groove 11 and is crushed into smaller raw materials after encountering the high-speed rotating cutting blade 149. After the raw materials that meet the size enter the raw material conveying hole 10, due to the spiral blade 14 The high-speed rotation of 8 will cause the smaller raw materials to move downward under the action of the spiral blades 148, forcing the smaller raw materials to be pressed into the gap between the inner wall of the conical fixed cover 141 and the outer circumferential surface of the inner conical rotating column 144. Since the gap size between the conical circumferential surface of the inner conical cavity 142 and the inner wall of the inner conical cavity 142 gradually decreases from top to bottom, the smaller raw materials will be gradually ground and finally enter between the upper grinding plate 143 and the lower grinding plate 145 to be ground again, thereby achieving the crushing and grinding of the zinc stearate raw materials. The ground powdered raw materials will fall on the outer inclined surface of the conical dividing plate 12 under the action of gravity. Under the action of gravity, the powdered raw materials are discharged outward through the raw material discharge port 13, and the outflowing powdered raw materials can be collected.

[0029] For the specific structure of the raw material crushing and grinding mechanism 14, please refer to Figure 3 and Figure 4, including a conical fixed cover 141 and an inner conical rotating column 144 fixedly mounted inside the conical component mounting cavity 9, the conical fixed cover 141 is provided with an inner conical cavity 142 inside, the bottom circumferential surface of the conical fixed cover 141 is provided with an upper grinding plate 143 extending outward, the inner conical rotating column 144 is located in the inner conical cavity 142, the bottom circumferential surface of the inner conical rotating column 144 is provided with a lower grinding plate 145 with an integral structure therewith, the bottom end of the inner conical rotating column 144 is provided with an inner concave upper shaft fixing groove 146, the top end of the inner conical rotating column 144 is provided with an upper rotating shaft 147 with an integral structure therewith and extending upward, the upper rotating shaft 147 is provided with an upper rotating shaft 147 with an integral structure therewith and extending upward, The shaft body of the shaft 147 passes through the raw material conveying hole 10 and the raw material input groove 11. The upper rotating shaft 147 is provided with a spiral blade 148 which is an integral structure with the upper rotating shaft 147 on the periphery of the shaft body located inside the raw material conveying hole 10. In order to prevent the raw material from moving in the gap, it is necessary to have a gap between the spiral blade 148 and the inside of the raw material conveying hole 10 and the gap is not enough to allow the crushed raw material to move longitudinally along the gap. The upper rotating shaft 147 is fixedly installed with a cutting blade 149 which rotates with the upper rotating shaft 147 on the periphery of the shaft body located inside the raw material input groove 11. The structural radius of the circumferential surface of the lower grinding plate 145 is larger than the upper diameter of the conical dividing plate 12.

[0030] For grind size adjustability, see Figure 1 , Figure 2 , Figure 5 and Figure 6 , it is necessary to set up a grinding size control mechanism 15, which is internally provided with a polygonal telescopic shaft 1513 that can rotate with the rotor 5 of the driving motor 4 and can drive the inner conical rotating column 144 to rotate, and a piston body 1512 that generates an upward movement under the action of liquid pressure and drives the polygonal telescopic shaft 1513 to move upward. Before work, a hydraulic injection device is used to inject liquid into the annular liquid flow hole 158 through the No. 1 liquid flow hole 1515. Due to the fluidity of the liquid, an upward force is exerted on the piston body 1512, so that the piston body 1512 drives the polygonal telescopic shaft 1513 to move upward, and drives the inner conical rotating column 144 to move upward, thereby changing the distance between the inner conical rotating column 144 and the inner surface of the conical fixed cover 141, thereby changing the size of the raw material being ground. When the liquid injection is completed, the hydraulic injection device is removed, and the port of the No. 1 liquid flow hole 1515 is closed using a plunger.

[0031] For the specific structure of the grinding size control mechanism 15, please refer to Figure 5 and Figure 6, including a rotating hollow shell 151 and an annular hollow shell 157 located inside the movable cavity 7 of the lower component, the center of the annular hollow shell 157 is provided with a component mounting hole 1510 with upper and lower openings, the circumferential surface of the annular hollow shell 157 is provided with a plurality of horizontal fixing rods 1511 with an integral structure therewith and one end of which is fixed to the inner wall of the horizontal supporting base plate 1, one end of one of the horizontal fixing rods 1511 passes through the circumferential surface of the corresponding part of the vertical barrel body 6 and extends to the external space of the vertical barrel body 6, and the interior of the horizontal fixing rod 1511 is provided with a No. 1 liquid flow hole 1515 with an open end, and the interior of the annular hollow shell 157 is provided with a No. 1 liquid flow hole 1515 connected to the No. 1 liquid flow hole 1515 The annular liquid flow hole 158 at the other end, the interior of the rotating hollow shell 151 is provided with a longitudinal component movement cavity 154, the bottom end of the rotating hollow shell 151 is provided with a hollow rotating shaft 152 which is an integral structure with it and passes through the component mounting hole 1510, the bottom end of the hollow rotating shaft 152 is fixedly installed with an upper fixed plate 153, the interior of the hollow rotating shaft 152 is provided with a No. 2 liquid flow hole 156 which is connected to the bottom end of the longitudinal component movement cavity 154 at the top, the circumferential surface of the hollow rotating shaft 152 is installed in the component mounting hole 1510 through two mechanical sealing structures, and the circumferential surface of the hollow rotating shaft 152 is provided with three connecting liquid flow holes 156 and the annular liquid flow hole 158 The rotating hollow shell 151 has a liquid flow hole 159, and a piston body 1512 capable of axially moving along the longitudinal component movement cavity 154 is placed inside the longitudinal component movement cavity 154. The top area of ​​the rotating hollow shell 151 passes through the upper diameter of the conical dividing plate 12, and there is a movement gap between the circumferential surface of the rotating hollow shell 151 and the inner wall of the conical dividing plate 12. The top of the rotating hollow shell 151 is provided with a polygonal axial hole 155 connecting the external space and the longitudinal component movement cavity 154, and the upper end surface of the piston body 1512 is fixedly mounted with a polygonal telescopic shaft 1513 passing through the polygonal axial hole 155. In order to prevent the component from self-rotating, the polygonal axial hole 15 5 is consistent with the structural shape of the horizontal cross-section of the polygonal telescopic shaft 1513, both of which are polygonal structures, and the structural dimensions of the horizontal cross-section of the polygonal shaft hole 155 match the structural dimensions of the horizontal cross-section of the polygonal telescopic shaft 1513. The top end of the polygonal telescopic shaft 1513 is fixedly installed inside the upper shaft body fixing groove 146, and a coil spring 1514 in a compressed state is placed on the upper end surface of the piston body 1512, and the elastic strength of the coil spring 1514 is sufficient to keep the inner conical rotating column 144 in a stable state during operation. The mechanical sealing structure is required to form a closed area between the annular liquid flow hole 158 and the No. 3 liquid flow hole 159.

[0032] To prevent damage to components due to excessive resistance caused by material jamming, please refer to Figure 1 , Figure 2 and Figure 7 , a torque type linkage mechanism 16 needs to be set, which is provided with an outer rotating shell 161 capable of driving the upper fixed plate 153 to rotate, an inner rotating column 166 rotating with the rotor 5 and located inside the outer rotating shell 161, and an annular airbag sheet 165 embedded in the outer rotating shell 161 and capable of driving the inner rotating column 166 to drive the outer rotating shell 161 to rotate. Before working, a liquid is injected into the outer chamber a using a liquid injection device. Under the pressure of the liquid, the inner surface of the annular airbag sheet 165 will wrap around and resist against the inner rotating column. The outer circumferential surface of 166 forms a maximum static friction force between the annular airbag sheet 165 and the inner rotating column 166. During operation, once the raw material is too hard to cause the component to get stuck, and the torque resistance caused by the sticking is greater than the maximum static friction force, the rotor 5 will continue to drive the inner rotating column 166 to rotate, and the annular airbag sheet 165 will form a relative rotation phenomenon with the inner rotating column 166, and the outer rotating shell 161 will not continue to rotate, thereby preventing the occurrence of component damage caused by excessive resistance caused by the sticking of the raw material.

[0033] For the specific structure of the torque type linkage mechanism 16, please refer to Figure 7 , including an outer rotating shell 161 and an inner rotating column 166, the upper end surface of the outer rotating shell 161 is provided with a lower fixed plate 162 which is an integral structure with it and fixedly connected to the upper fixed plate 153, the inner part of the outer rotating shell 161 is provided with a component rotating cavity 163, the center of the outer rotating shell 161 is provided with a component mounting chamber 164, the inner rotating column 166 is installed in the component mounting chamber 164 through a bearing, and the bottom of the inner rotating column 166 passes through the bottom structure of the outer rotating shell 161. The outer rotating shell 161 has an annular airbag sheet 165 embedded in the periphery of the inner rotating column 166, and the annular airbag sheet 165 divides the component rotating cavity 163 into an inner chamber b and an outer chamber a. The outer circumferential surface of the outer rotating shell 161 is provided with a liquid injection channel 167 connected to the outer chamber a, and a liquid valve 169 is installed inside the liquid injection channel 167.

[0034] The specific working principle of the present invention is to use a hydraulic injection device, connect the liquid circuit of the liquid injection device with the first liquid flow hole 1515, and put the zinc stearate raw material to be ground into the raw material input tank 11;

[0035] The driving motor 4 is started, and the rotor 5 drives the components to rotate through the torque linkage mechanism 16 and the grinding size control mechanism 15. The zinc stearate raw material is put into the raw material input groove 11, and is broken into smaller raw materials after encountering the high-speed rotating cutting blade 149. After the raw materials that meet the size enter the raw material conveying hole 10, the high-speed rotation of the spiral blade 148 causes the smaller raw materials to move downward under the action of the spiral blade 148, forcing the smaller raw materials to be pressed into the inner wall of the conical fixed cover 141 and the outer wall of the inner conical rotating column 144. In the gap between the circumferential surfaces, since the gap size between the conical circumferential surface of the inner conical cavity 142 and the inner wall of the inner conical cavity 142 gradually decreases from top to bottom, smaller raw materials will be gradually ground, and finally enter between the upper grinding plate 143 and the lower grinding plate 145 to be ground again, thereby achieving the crushing and grinding of the zinc stearate raw material. The ground powdered raw material will fall on the outer inclined surface of the conical dividing plate 12 under the action of gravity. Under the action of gravity, the powdered raw material is discharged outward through the raw material discharge port 13, and the outflowing powdered raw material can be collected.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
