Description

Technical Field

[0001] The present invention belongs to the technical field of plastic particle sorting, and in particular relates to intelligent sorting equipment and a method for producing plastic particles. Background Art

[0002] During the production, recycling or processing of plastics, some tiny metal particles or impurities will be mixed in. These metal impurities will affect the purity and quality of plastic particles. In some high-end applications or specific fields, the purity and quality requirements of plastic particles are very high. Any tiny metal impurities may have adverse effects on the product. Therefore, in order to improve product quality, the metal impurities in plastic particles need to be screened out; Based on the prior art, it is found that when metal particles or impurities in plastic particles are screened out, magnetic adsorption is mostly used. After the metal particles or impurities in the plastic particles are screened out, when the next screening operation is carried out, the screened plastic particles need to be transferred to another sorting equipment for sorting. This method makes the entire sorting process cumbersome and labor-intensive. In addition, in some recycled plastics, after the plastics are crushed into plastic particles, the plastic particles are easily wrapped with metals. However, it is difficult to screen out the plastic particles wrapped with metals by only sorting through magnetic adsorption, which further affects the purity and quality of the plastic particles.

[0014] The advantages and positive effects of the present invention are: (1) By pouring water into the sorting barrel and then pouring plastic particles into the sorting barrel, the water can make the plastic particles float on the water surface, while the metal debris and plastic particles wrapped with metal in the plastic particles will be at the bottom of the inner side of the sorting barrel and loaded into the carrying plate.

[0024] A drain pipe 11 is installed at the front of the chassis 1 to drain the water and plastic particles overflowing from the sorting bucket 2 .

[0025] The driving mechanism includes an electric actuator 201, a bracket 202, a housing 204, a motor II 205, a gear I 206 and a gear II 208; two electric actuators 201 are fixedly connected to the lower surface of the chassis 1, and the electric actuators 201 are electric push rods; the telescopic parts of all electric actuators 201 are fixedly connected to a bracket 202; the bracket 202 is rotatably connected to the filter disc 203; the middle part of the lower surface of the bracket 202 is fixedly connected to the housing 204; the motor II 205 is fixedly connected to the inside of the housing 204; the output shaft of the motor II 205 is fixedly connected to the gear I 206; the upper part of the sieve disc 207 is fixedly connected to the gear II 208; the gear II 208 is meshed with the gear I 206.

[0026] The inflation mechanism includes an intake ring 211, a cylinder I 216 and a disturbance plate 217; the intake ring 211 is rotatably connected to the upper part of the circular tube 210, and a through hole I connected to the intake ring 211 is opened on the circular tube 210; the lower part of the intake ring 211 is fixedly connected and connected to the cylinder I 216, and an electromagnet is arranged inside the cylinder I 216; four disturbance plates 217 are equidistantly fixedly connected and connected to the outer ring surface of the cylinder I 216.

[0027] The magnetic separation mechanism includes a carrying plate 212, a circular ring 213, a nozzle 214 and a magnetic attraction plate 215; the carrying plate 212 is installed on the inner bottom of the sorting barrel 2; the circular ring 213 is fixedly connected to the lower surface of the sorting barrel 2; two nozzles 214 are fixedly connected and connected to the circular ring 213, and a circular hole matching the nozzle 214 is opened on the carrying plate 212; the magnetic attraction plate 215 is fixedly connected to the inner bottom of the carrying plate 212.

[0028] A filter screen is provided inside the nozzle 214 to prevent the nozzle 214 from being blocked by plastic particles.

[0029] It also includes a guide plate 21; the guide plate 21 is fixedly connected to the outer side of the sorting barrel 2; the chassis 1 is arranged in a horizontal shape, and the sorting barrel 2 is arranged in an inclined shape as a whole.

[0030] When sorting plastic particles, take the six fan-shaped filter screens on the filter disc 203 as an example. The six fan-shaped filter screens are divided into three groups: the three groups of filter screens on the filter disc 203 are divided into three levels of large, medium and small according to the size of the filter screen aperture. The external pump for air transmission is connected to the air inlet ring 211 and the ring 213 in advance, and water is injected into the sorting barrel 2, and the water injection amount is not more than two-thirds of the volume of the sorting barrel 2. The initial position of the filter disc 203 is located above the sorting barrel 2, so that the crushed The plastic particles are poured into the sorting barrel 2. After the plastic particles are poured into the sorting barrel 2, the dust in the plastic particles will be fused in the water, and the gravel in the plastic particles will settle to the inner bottom of the sorting barrel 2 and be loaded into the carrying plate 212. At the same time, the plastic particles will float on the water surface, and the metal debris in the plastic particles will settle to the inner bottom of the sorting barrel 2, and some of the plastic particles wrapped with metal will also settle to the inner bottom of the sorting barrel 2 and be loaded into the carrying plate 212. At the same time, the magnetic attraction plate 215 is powered on to absorb the metal debris and the plastic particles wrapped with metal, so that the metal debris and the plastic particles wrapped with metal are absorbed into the carrier plate 212, reducing the possibility of the metal debris and the plastic particles wrapped with metal floating up, and impurities such as dust and gravel in the plastic particles can be screened out by water.

[0031] Then, the two electric actuators 201 are controlled to start and drive the bracket 202 to move downward. The movement of the bracket 202 drives all the connected parts to move, so that the filter plate 203 and the sieve plate 207 are moved into the sorting barrel 2, and the plastic particles are squeezed through the filter plate 203. At the same time, the motor II 205 is controlled to start, and the output shaft of the motor II 205 rotates to drive the gear I 206 to rotate, and the gear I 206 rotates to drive the gear II 208 to rotate, and the gear II 208 rotates to drive the sieve plate 207 to rotate, so that the two fan-shaped through grooves 2071 on the sieve plate 207 are aligned with the group of filter screens with the smallest aperture on the filter plate 203, so that Water and small plastic particles can pass through a group of filters with the smallest aperture on the filter disc 203 and two fan-shaped through grooves 2071 on the sieve disc 207, and the external air pump is controlled to operate to transport gas into the air intake ring 211 and the circular ring 213, so that the gas enters the cylinder I 216 along the circular tube 210, and finally ejects from all the disturbance plates 217, and the gas enters the nozzle 214 along the circular ring 213 and ejects from the nozzle 214. Since the nozzle 214 is higher than the magnetic attraction plate 215, the gas ejected from the nozzle 214 will not blow directly to the metal debris and plastic particles wrapped with metal adsorbed by the magnetic attraction plate 215; When the gas is blown into the water, bubbles are formed and move upward, thereby turning over the plastic particles floating on the water surface through the gas, so that the plastic particles move in the water, and then the small plastic particles can pass through the group of filters with the smallest aperture on the filter plate 203 and the two fan-shaped through grooves 2071 on the sieve plate 207. At the same time, the motor I 209 is controlled to start, and the output shaft of the motor I 209 rotates to drive the circular tube 210 to rotate, and the rotation of the circular tube 210 drives the cylinder I 216 to rotate, and the rotation of the cylinder I 216 drives all the disturbance plates 217 to rotate, so that the plastic particles are disturbed by the rotation of all the disturbance plates 217, so that the water and plastic particles are further mixed more evenly. When the filter plate 203 moves downward to the limit, the motor I 209 is controlled to stop working, and the external pump is controlled to stop working. At this time, the water surface is still, and the plastic particles that have not passed through the group of filter screens with the smallest aperture on the filter plate 203 will always be against the lower surface of the filter plate 203 due to the existence of buoyancy, and the plastic particles that have passed through the filter screens will continue to float on the surface of the water above the filter plate 203. Then, the two electric actuators 201 are controlled to start and drive the bracket 202 to gradually move upward, thereby driving the small plastic particles to move upward. As the filter disc 203 moves upward, the water located on the upper part of the filter disc 203 will flow out through a group of filter screens with the smallest aperture on the filter disc 203. At the same time, the small plastic particles will remain in the filter disc 203 because the large plastic particles will always press against the lower surface of the filter disc 203, and will be located on the upper surface of the sieve disc 207 until the filter disc 203 and the sieve disc 207 are separated from the water surface. When the filter disc 203 and the sieve disc 207 are separated from the water surface, the filter disc 203 and the sieve disc 207 are separated from the continuous upward movement, thereby causing the filter disc 203 to contact and separate from the sorting barrel 2, thereby pouring the small plastic particles onto the guide plate 21 through the inclined filter disc 203 and the sieve, and then collecting the plastic particles through the external collection box, thereby completing the sorting operation of the small plastic particles.

[0032] In order to prevent small plastic particles from remaining in the filter disc 203 and the sieve disc 207, when the filter disc 203 and the sieve disc 207 move up to the upper layer of the water body, that is, when the filter disc 203 and the sieve disc 207 are close to the water surface but have not yet left the water surface, the control motor II 205 is started, and the output shaft of the motor II 205 rotates to drive the gear I 206 to rotate, and the rotation of the gear I 206 drives all the connected parts to rotate, thereby driving the sieve disc 207 to rotate, and then all the filter screens on the filter disc 203 are blocked by the sieve disc 207, so that a small amount of water will be loaded in the filter disc 203 and the sieve disc 207, and then when the filter disc 203 and the sieve disc 207 pour out the plastic particles, the water and the plastic particles can be poured toward the guide plate 21 together, thereby avoiding the problem of plastic particles remaining in the filter disc 203 and the sieve disc 207.

[0033] And when the screening of small-volume plastic particles is completed, the sieve plate 207 is rotated in the same manner as described above to sort them in order from small to large. First, the two fan-shaped through grooves 2071 on the sieve plate 207 are aligned with a group of filter screens with medium apertures, and then the plastic particles are sorted. Finally, the two fan-shaped through grooves 2071 on the sieve plate 207 are aligned with a group of filter screens with the largest apertures, and then the plastic particles are sorted, thereby realizing the sorting of plastic particles by volume until all plastic particles are sorted.

[0034] Embodiment 2: Based on Embodiment 1, according to Figure 2 and Figure 7 As shown, it also includes an auxiliary sorting system; the auxiliary sorting system is connected to the sieve plate 207; the auxiliary sorting system includes a connecting rod 301, an air guide ring 302 and an air pipe 303; two connecting rods 301 are fixedly connected to the middle of the lower surface of the sieve plate 207; the lower ends of all the connecting rods 301 are commonly fixedly connected to an air guide ring 302; and a through hole II connected to the air guide ring 302 is opened on the circular tube 210; two air pipes 303 are fixedly connected and connected to the air guide ring 302, and the position of the air pipe 303 corresponds to the position of the fan-shaped through groove 2071 on the sieve plate 207, and the air outlet on the air pipe 303 faces upward.

[0035] When the plastic particles are filtered through each set of filter screens on the filter disc 203, some of the plastic particles will be blocked, resulting in the plastic particles corresponding to the filter screen aperture cannot be quickly filtered, resulting in low efficiency in sorting the plastic particles. To solve the above problem, when gas enters the circular tube 210, gas will enter the two air pipes 303 through the air guide ring 302, and because the positions of the two air pipes 303 correspond to the positions of the fan-shaped through grooves 2071 on the sieve disc 207, the air outlet holes on the air pipes 303 face upward, and then pass through the circular tube 210. The air pipe 303 can blow gas toward the fan-shaped through-groove 2071 on the sieve plate 207, thereby blowing the plastic particles toward the fan-shaped through-groove 2071 on the sieve plate 207, that is, it can make the plastic particles quickly move to a corresponding group of filter screens on the filter plate 203, so that the plastic particles corresponding to the filter screen aperture can quickly pass through the filter screen to complete the sorting, and rotate and disturb the plastic particles through all the disturbance plates 217, so that the plastic particles that do not meet the filtering conditions are kept away from the filter screen to avoid clogging the filter screen.

[0036] Embodiment 3: Based on Embodiment 2, according to Figure 2 and Figure 8-Figure 10 As shown, it also includes a secondary magnetic separation system; the secondary magnetic separation system is connected to the disturbance plate 217; the secondary magnetic separation system includes a barb 2171, a top block 2172, a cylinder II 401, a column 402, a telescopic column 4021, a truncated table 403 and an electromagnetic plate 404; a magnet is arranged at the lower part of the cylinder I 216; each disturbance plate 217 is fixedly connected to a barb 2171 at one end away from the cylinder I 216, and the barb 2171 is made of a metal spring; a slot matching the barb 2171 is opened on the carrier plate 212; each disturbance plate 217 are fixedly connected with a top block 2172; a cylinder II 401 is fixedly connected to the middle part of the lower surface of the sorting barrel 2; a column 402 is slidably connected to the inner side of the cylinder II 401, and a spring is fixedly connected between the column 402 and the cylinder II 401; four telescopic columns 4021 are fixedly connected to the upper part of the column 402; a round table 403 is slidably connected to the upper part of the column 402, and a groove matching the telescopic column 4021 is opened on the round table 403, and a magnet is arranged on the upper part of the round table 403; three electromagnetic plates 404 are fixedly connected to the lower part of the outer ring surface of the round table 403 in an equidistant manner.

[0037] The electromagnetic plates 404 and the magnetic attraction plates 215 are arranged in a staggered manner to better absorb metal debris and plastic particles wrapped with metal.

[0038] An intelligent sorting method for plastic granule production comprises the following steps: S1: flotation, water is poured into the sorting bucket 2, and all plastic particles are poured into the sorting bucket 2, so that the plastic particles float on the water surface, while metal debris and plastic particles wrapped with metal will settle; S2: Magnetic separation, the magnetic suction plate 215 is powered on to absorb the metal debris and the plastic particles wrapped with metal; S3: sorting by volume, by aligning the two fan-shaped through grooves 2071 on the sieve plate 207 with a set of filter screens on the filter plate 203; S4: Spraying gas into the water through the disturbance plates 217 and the nozzles 214, and rotating and disturbing the plastic particles through all the disturbance plates 217; S5: Discharging, pouring out the plastic particles by moving the inclined filter plate 203 and the sieve plate 207 upward, and pouring out the metal scraps and the plastic particles wrapped with metal in the carrying plate 212.

[0039] As the plastic particle sorting continues, the amount of metal debris and metal-wrapped plastic particles contained in different batches of plastic particles will be different, resulting in the gradual increase of metal debris and metal-wrapped plastic particles in the plastic particles during the continuous sorting operation, which in turn causes the adsorption performance of the magnetic suction plate 215 to decrease. By controlling the two electric actuators 201 to start and drive the bracket 202 to move downward, the movement of the bracket 202 drives all the connected parts to move, thereby causing the cylinder I 216 and the four disturbance plates 217 to move downward synchronously until the cylinder I 216 moves to the inside of the truncated table 403, and then the electromagnet in the cylinder I 216 is controlled to be energized and operated, thereby attracting the magnet on the upper part of the truncated table 403, as shown in FIG. Fig.10 As shown, and the barb 2171 does not contact the slot on the carrier plate 212, and then the two electric actuators 201 are controlled to start and drive the bracket 202 to move upward, thereby driving all the connected parts to move upward, so that the cylinder I 216 moves to drive the round table 403 to move, and the round table 403 moves to drive the electromagnetic plate 404 to move upward, until the two grooves below the round table 403 move to the two telescopic columns 4021 above the column 402, and the round table 403 is limited by the two telescopic columns 4021 above, and at the same time, the electromagnet provided in the cylinder I 216 is controlled to be powered off, so that all the electromagnetic plates 404 move upward, and the electromagnetic plates 404 and the magnetic suction plates 215 are staggered, so that the three electromagnetic plates 404 can continuously absorb metal debris and plastic particles wrapped with metal, so that the sorting operation can be carried out continuously, thereby achieving the improvement of the magnetic suction effect while improving the sorting efficiency of plastic particles.

[0040] When the plastic particles floating on the water surface are evenly sorted, it is necessary to pour out the metal scraps and the plastic particles wrapped with metal, and the two electric actuators 201 are controlled in the same way as above to start and drive the bracket 202 to move downward, and the movement of the bracket 202 drives all the connected parts to move, so that the cylinder I 216 and the four disturbance plates 217 move downward synchronously until the cylinder I 216 moves to the inside of the round table 403. At this time, all the top blocks 2172 squeeze the round table 403, so that the round table 403 moves downward and resets. At the same time, the cylinder I 216 squeezes the column 402, so that the column 402 moves downward and compresses the column 402. The spring between the column 402 and the cylinder II 401 enables all the disturbance plates 217 to move downward continuously, so that the four barbs 2171 move downward to the corresponding slots on the carrier plate 212, and then the carrier plate 212 is hooked by the four barbs 2171, and then the two electric actuators 201 are controlled to start and drive the bracket 202 to move upward and reset, until the carrier plate 212 moves upward to the top of the sorting barrel 2, and then the metal debris and plastic particles wrapped in metal loaded in the carrier plate 212 are manually poured out, so as to clean the carrier plate 212, thereby realizing automatic cleaning and effectively reducing the manpower burden.
