Description

Technical Field

[0001] The present invention relates to the field of plastic particle production, and particularly to a real-time cooling device for plastic particle production and processing. Background Art

[0002] As an important way to alleviate resource shortage and environmental pollution problems, plastic recycling usually involves granulating waste plastics after recycling for use as raw materials in subsequent blow molding and thermoforming processes. However, in the granulation process, when cooling the extruded strip through a cooling pool to transform the strip from a molten state to a solid state, due to the different requirements of plastic particle production of different materials for the process parameters of the extruder (such as temperature field distribution, cavity cleanliness): when the accuracy of the extruder temperature control system is insufficient (the fluctuation exceeds ±5 °C) or during the process of workers debugging the machine, the extruded strip will have a surface plasticized cortex (an aggregate of resin particles that are not completely melted) and dispersed particles (unmelted fillers or impurities). Then, in the initial stage when the extruded strip enters the cooling water tank (when the contact water temperature difference > 40 °C), due to the rapid solidification of the surface melt (cooling rate > 20 °C / s), shrinkage stress is generated, resulting in the peeling of the plasticized cortex and dispersed particles from the matrix interface, forming exfoliated residues floating on the water surface or deposited at the bottom of the water tank. For the exfoliated residues floating on the water surface, they are easily adhered to the surface of the extruded strip during the traction process of the extruded strip in and out of the water tank, forming pollution spots and affecting the quality of subsequent plastic particles. Furthermore, during the process of the extruded strip entering the water tank and the surface of the extruded strip rapidly cooling and solidifying, some plasticized cortex and dispersed particles that are strongly adhered to the extruded strip body will combine with the extruded strip body and are difficult to fall off, resulting in the rough surface of the subsequent cut plastic particles, and causing problems such as uneven plasticization, insufficient filling, dimensional deviation, and mold wear during subsequent blow molding processing.

[0021] The transmission component includes a fixing cover 108, a motor 109, a belt 110, a driving wheel 111 and a driven wheel 112; A fixing cover 108 is fixedly connected inside the cavity 10302.

[0022] The impurity removing component includes a connecting plate 104 and a filter screen 105; A connecting plate 104 is slidably connected to the front side of the partition plate 103; Three filter screens 105 are fixedly connected to the connecting plate 104, and the mesh holes of the filter screens 105 gradually become smaller from top to bottom; Each filter screen 105 is located inside the circulation groove 10301.

[0023] A handle 10401 is provided on the front side of the connecting plate 104, which facilitates workers to pull out the connecting plate 104 and the filter screen 105 to clean the impurities intercepted on the filter screen 105.

[0024] All the filter screens 105 are inclined from the upper left to the lower right.

[0025] It also includes a temperature sensor 117; a temperature sensor 117 is fixedly connected in each of the rapid cooling tank 1001 and the continuous curing tank 1002.

[0026] The working principle of the above embodiment is as follows: First, the worker connects the water inlet pipe 2 and the drain pipe 3 to the external cooling water conveying equipment; then starts the external cooling water conveying equipment. At this time, the cooling water flows into the water tank 1 through the water inlet pipe 2, and then the cooling water flows from left to right in the water tank 1 and finally is discharged through the drain pipe 3. During this process, the extruded strip 555 is conveyed from left to right in the water tank 1 by the conveying equipment. After the extruded strip 555 enters the water tank 1, the cooling water in the water tank 1 cools down the extruded strip 555; after the extruded strip 555 is cooled down, it will gradually solidify and form. It should be noted that after the extruded strip 555 enters the water tank 1, the first fixing block 4 and the limiting wheel 5 limit the extruded strip 555 to prevent the extruded strip 555 from being wound together during the movement.

[0027] It is considered that the cooling of the extruded strip 555 needs to go through two processes: rapid surface cooling and gradual internal cooling. To avoid excessive temperature difference between the extruded strip 555 and the cooling water when the extruded strip 555 first enters the water tank 1, which may cause cracking on the surface of the extruded strip 555, in the prior art, the temperature of the cooling water required for the rapid surface cooling of the extruded strip 555 is usually set at 15 - 25 °C. To ensure the cooling efficiency of the interior of the extruded strip 555, the temperature of the cooling water required for the gradual internal cooling of the extruded strip 555 is usually set at 5 - 15 °C. Therefore, the water tank 1 is divided into a rapid cooling tank 1001 and a continuous curing tank 1002 by the partition plate 103. The left side of the flow-through tank 10301 is the water inlet, and the right side is the water outlet. And on the partition plate 103, the height of the water inlet is higher than that of the water outlet. Therefore, the worker can control the water inflow of the water inlet pipe 2 and the water drainage of the drain pipe 3 to make the water level in the rapid cooling tank 1001 higher than the water inlet of the flow-through tank 10301, and the water level in the continuous curing tank 1002 lower than the water outlet of the flow-through tank 10301. At this time, the water in the rapid cooling tank 1001 will continuously flow into the continuous curing tank 1002 through the flow-through tank 10301. During this process, the extruded strip 555 first enters the rapid cooling tank 1001 for rapid cooling and curing, and then the extruded strip 555 passes through the cavity 10302 and the corresponding sealing ring 10304 into the continuous curing tank 1002 for continuous internal cooling and curing. It should be noted that the extruded strip 555 will closely fit with the sealing ring 10304 made of rubber material, thereby sealing the cavity 10302. Therefore, after the water tank 1 is divided into a rapid cooling tank 1001 and a continuous curing tank 1002 by the partition plate 103, the worker can add the optimal cooling water at 15 - 25 °C required for the rapid surface cooling of the extruded strip 555 into the rapid cooling tank 1001 through the water inlet pipe 2; when the cooling water that has absorbed heat in the rapid cooling tank 1001 flows into the continuous curing tank 1002, the worker can cool the heated cooling water in the continuous curing tank 1002 through the refrigeration sheet 116, and reduce the temperature of the cooling water in the continuous curing tank 1002 to 5 - 15 °C; thus avoiding the high temperature of the cooling water flowing into the continuous curing tank 1002 from affecting the cooling effect of the cooling water on the interior of the extruded strip 555. And after being separated by the partition plate 103, the cooling water will only flow from the rapid cooling tank 1001 into the continuous curing tank 1002. Therefore, when using the refrigeration sheet 116 to cool the cooling water in the continuous curing tank 1002, it will not affect the cooling water in the rapid cooling tank 1001.

[0028] Furthermore, considering that in the initial stage when the extruded strip 555 enters the cooling water tank 1 (the contact water temperature difference > 40°C), that is, when it enters the rapid cooling tank 1001, due to the rapid solidification of the melt on the surface of the extruded strip 555 (cooling rate > 20°C / s), shrinkage stress is generated, resulting in the peeling of the plasticized cortex and dispersed particles from the interface of the matrix, forming exfoliated residues floating on the water surface or deposited at the bottom of the water tank 1. For the exfoliated residues floating on the water surface, they are easily adhered to the surface of the extruded strip 555 during the process of the extruded strip 555 entering and leaving the water tank 1, forming pollution spots and affecting the quality of plastic particles. Therefore, when the cooling water on the surface of the rapid cooling tank 1001 flows into the continuous solidification tank 1002 through the flow channel 10301, the residues on the surface of the rapid cooling tank 1001 will flow into the flow channel 10301 along with the water flow. Then, the residues in the water flow are filtered by the filter screen 105. There are three filter screens 105, and the mesh sizes of the three filter screens 105 gradually decrease from top to bottom. Thus, the residues of different sizes are filtered layer by layer through the filter screens 105 with different mesh sizes. All the filter screens 105 are inclined from the upper left to the lower right. A connecting plate 104 is fixedly connected to the right sides of all the filter screens 105. Therefore, with the scouring of the water flow, the impurities intercepted on the surface of the filter screen 105 will be washed to the angle between the filter screen 105 and the connecting plate 104, preventing the filter screen 105 from being quickly blocked and affecting the flow of the cooling water. After using for a period of time, the worker can pull out the connecting plate 104, and then pull out the filter screen 105 to clean the residues in the filter screen 105. Thus, the residues on the surface of the rapid cooling tank 1001 are cleaned by this method, and at the same time, the residues are prevented from entering the continuous solidification tank 1002, ensuring the cleanliness of the cooling water in the continuous solidification tank 1002. Therefore, when the cooling water in the continuous solidification tank 1002 is discharged from the drain pipe 3 for circulating flow, there is no need to use additional filtering equipment to filter the cooling water in the continuous solidification tank 1002, saving costs and improving production efficiency. Moreover, when the water tank 1 is regularly cleaned later, only the residues deposited at the bottom of the rapid cooling tank 1001 need to be cleaned, and there is no need to clean the continuous solidification tank 1002, greatly reducing the cleaning difficulty of the equipment.

[0029] Furthermore, in the initial stage when the extruded strip 555 enters the cooling water tank 1, during the process of the rapid cooling and solidification of the surface of the extruded strip 555, some plasticized cortex and dispersed particles that are strongly adhered to the body of the extruded strip 555 will combine with the body of the extruded strip 555 and are difficult to fall off, resulting in uneven surfaces of the subsequent cut plastic particles and rough finished products, seriously affecting the quality of the plastic particles after granulation. Therefore, as Figures 4-6As shown in the figure: When the extruded strip 555 passes through the corresponding sealing ring 10304 and enters the cavity 10302, the extruded strip 555 will pass through the scraping ring 114 and the fixed ring 113, and then the plasticized cortex and dispersive particles on the surface of the extruded strip 555 will be scraped off by the scraping ring 114; Further, during the process of cooling water flowing from the rapid cooling tank 1001 into the continuous curing tank 1002, a part of the filtered cooling water in the circulation tank 10301 will flow into the square tank 10303, then enter the guiding pipe 107, and then flow to the corresponding scraping ring 114 through the guiding pipe 107, and then use the filtered cooling water to wash the residues scraped on the scraping ring 114 to the bottom of the cavity 10302, and then discharge them through the slag discharge pipe 115, so as to avoid the accumulation of the scraped residues on the scraping ring 114, resulting in the residues being brought between the scraping ring 114 and the extruded strip 555 when the extruded strip 555 moves relative to the scraping ring 114, that is, to avoid causing surface defect problems of the extruded strip 555.

[0030] Further, it is also considered that when the residues scraped from the surface of the extruded strip 555 are rinsed with cooling water, the cooling water rinses from top to bottom, and the rinsing effect on the residues at the bottom of the extruded strip 555 is poor, resulting in the residues accumulated at the bottom of the scraping ring 114 still being brought between the scraping ring 114 and the extruded strip 555 when the extruded strip 555 moves relative to the scraping ring 114, resulting in the residues clamped between the scraping ring 114 and the extruded strip 555 scraping the surface of the extruded strip 555 during the traction movement of the extruded strip 555, causing damage to the surface of the extruded strip 555; Therefore, during the process of scraping the residues on the surface of the extruded strip 555 by the scraping ring 114, the motor 109 is started to drive the belt 110 and the driving wheel 111 to rotate regularly, and then drive the driven wheel 112, the fixed ring 113 and the scraping ring 114 to rotate regularly. Taking the left-to-right view as the reference, the scraping ring 114 is driven by the motor 109 to rotate counterclockwise one week per minute regularly, and then by this method, the contact part between the scraping ring 114 and the lower surface of the extruded strip 555 is continuously changed, so as to ensure the overall rinsing effect of the cooling water on the scraping ring 114.

[0031] On the basis of the above technical effects, the present invention also has the following advantages: As Figure 4 shown: A handle 10401 is arranged on the front side of the connecting plate 104, which is convenient for workers to pull out the connecting plate 104 and the filter screen 105 to clean the impurities intercepted on the filter screen 105.

[0032] As Figure 2 and Figure 9As shown: The temperature of the cooling water in the rapid cooling tank 1001 and the continuous curing tank 1002 is detected in real time by the temperature sensor 117. Then, the worker can adjust the temperature of the cooling water in the rapid cooling tank 1001 and the continuous curing tank 1002 to the optimal state according to the real-time detection data, improving the cooling effect of the extruded strip 555.

[0033] Example 2: On the basis of Example 1, as Figure 1 , Figure 8 and Figure 9 shown, it further includes assembling blocks 101 and a cover plate 102; the right part of the water tank 1 is composed of three assembling blocks 101 and a cover plate 102. The assembling blocks 101 are bolted to each other, the assembling blocks 101 are bolted to the water tank 1, and the assembling blocks 101 are bolted to the cover plate 102.

[0034] It further includes sleeves 106; five sleeves 106 are fixedly connected to the upper side of the cover plate 102, and sponge blocks are arranged in each sleeve 106; each extruded strip 555 passes through the sponge block in the corresponding sleeve 106.

[0035] A method for using a real-time cooling device for plastic particle production and processing is as follows: Step 1, first, the worker installs or removes the assembling blocks 101 according to the usage requirements of plastic particles of different materials, and then connects the water inlet pipe 2 and the drain pipe 3 to an external cooling water conveying device and starts the external cooling water conveying device to make the cooling water flow in the water tank 1; Step 2, the worker sends the extruded strip 555 into the water tank 1 through a conveying device for cooling operation, and sends the cooled extruded strip 555 into a cutting device for granulation; Step 3, the worker regularly (4 hours - 8 hours) pulls out the connecting plate 104 to clean the residue on the filter screen 105, and regularly (1 week - 2 weeks) cleans the residue deposited at the bottom of the rapid cooling tank 1001.

[0036] The working principle of the above embodiments is as follows: Furthermore, after the surface of the extruded strip 555 comes into direct contact with water, it will quickly cool and solidify, while the cooling process inside the extruded strip 555 takes some time. Since the thermal conductivity of the extruded strip 555 made of different materials is different, the cooling time required for the extruded strip 555 of different materials is also different. When producing extruded strips 555 of different materials, the fixed length of the water tank 1 makes it impossible to flexibly adjust the residence time (i.e., cooling time) of the extruded strip 555 in the water tank 1. Therefore, the water tank 1 is composed of the water tank 1, the assembling block 101 and the cover plate 102. After the water tank 1 is divided into a rapid cooling tank 1001 and a continuous solidification tank 1002 by the partition plate 103, the length of the rapid cooling tank 1001 where the surface of the extruded strip 555 cools and solidifies remains unchanged. Workers can disassemble or add assembling blocks 101 according to the cooling time requirements of the extruded strip 555 of different materials, thereby shortening or lengthening the length of the continuous solidification tank 1002. Furthermore, without changing the conveying speed of the extruded strip 555, the residence time of the extruded strip 555 in the continuous solidification tank 1002 can be shortened or lengthened, ensuring the cooling effect inside the extruded strip 555 and improving the adaptability of the water tank 1.

[0037] Furthermore, considering that after the extruded strip 555 is cooled by water in the water tank 1, more or less part of the cooling water will be adsorbed on the surface of the extruded strip 555, resulting in the need to dry the extruded strip 555 subsequently, which affects the production efficiency and increases the production cost. Therefore, when the extruded strip 555 is pulled out of the water tank 1, it will pass through the sleeve 106 on the upper side of the cover plate 102. At this time, the extruded strip 555 will contact the sponge block in the sleeve 106, and then the cooling water on the surface of the extruded strip 555 will be wiped off by the sponge block.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
