Description

Technical Field

[0001] The invention relates to the field of cable production, and in particular to a drying device and a production process for aluminum alloy medium-voltage cable production. Background Art

[0002] In the production process of aluminum alloy medium-voltage cables, in order to reduce the pollution caused by waste cable insulation layers to the environment and reduce production costs, plastic particles crushed from waste cable insulation layers can be recycled. Since the insulation layers of these waste cables are often attached with pollutants such as oil and dust, before reuse, the plastic particles need to be cleaned by special cleaning equipment and the residual moisture after cleaning is removed by a drying device. The plastic particles after cleaning and drying will then be sent to an extruder or other molding equipment for the manufacture of new cable products. This method not only helps to protect the environment, but also can effectively save resources and improve economic benefits.

[0003] A Chinese patent with publication number CN116945410A discloses a plastic particle drying device, which has an inclined circular plate so that the plastic particles can move upward along the circular plate when being dried, thereby avoiding the problem of plastic particle accumulation; however, when the wet plastic particles are dried, due to the centrifugal force, these particles will be squeezed against each other, and some plastic particles will aggregate into agglomerates.

[0036] The housing 3 is provided with a drainage hole 3001, and the drainage hole 3001 is connected to an external water storage device through a pipeline.

[0037] It also includes a baffle 9 and a rotating shaft 10; the rotating ring 6 is rotatably connected to two baffles 9; the supporting plate 2 is fixedly connected to the rotating shaft 10, and the rotating shaft 10 is rotatably connected to the baffle 9, and the rotating shaft 10 is configured to be hollow, and the rotating shaft 10 is provided with a plurality of air outlet holes, and the rotating shaft 10 is connected to an external hot air conveying device; the rotating ring 6 is provided with a plurality of air outlet grooves 6001, and the air outlet grooves 6001 are provided with filters to prevent plastic particles from entering the rotating ring 6 through the air outlet grooves 6001.

[0038] It also includes an electric push rod Ⅰ101 and a rotating plate 102; the workbench 1 is fixedly connected to two electric push rods Ⅰ101; the telescopic ends of all the electric push rods Ⅰ101 are commonly fixedly connected to the rotating plate 102; the support plate 2 is provided with a connecting block 2001, and the connecting block 2001 is slidably connected to the support plate 2; the rotating plate 102 is rotatably connected to the connecting block 2001.

[0039] It also includes a rotating roller 201, a sponge belt 202 and a motor III 203; two rotating rollers 201 are rotatably connected to the outer side of the outer shell 3; all the rotating rollers 201 are wrapped with a sponge belt 202, a plurality of air holes are opened on the sponge belt 202, and the sponge belt 202 passes through the inside and outside of the outer shell 3; the outer shell 3 is fixedly connected to the motor III 203, and the output shaft of the motor III 203 is fixedly connected to one of the rotating rollers 201.

[0040] The working steps of the above embodiment are: first, the staff opens the front cover 5001, and then inputs the cleaned plastic particles into the space between the rotating ring 6 and the water-spinning net 4. Since the housing 3, the water-spinning net 4 and the rotating ring 6 are inclined with the front higher and the back lower in the initial state, the plastic particles will slide backward when entering between the rotating ring 6 and the water-spinning net 4, so as to prevent the plastic particles from accumulating at the front end and affecting the feeding; then, when the rotating ring 6 and the water-spinning net 4 have entered half of the capacity of the plastic particles, the input of the plastic particles is stopped. Then the staff closes the front cover 5001; then the electric push rod Ⅰ101 pulls the rotating plate 102 to move downward, and pulls the support plate 2 and all the parts connected to it downward through the rotating plate 102, so that the connecting block 2001 slides on the support plate 2. When the lower side of the support plate 2 rotates to be parallel to the workbench 1, the electric push rod Ⅰ101 stops pulling, even if the rotating ring 6 and the water-spinning net 4 rotate to a horizontal state, to prevent the plastic particles from piling up to one side during the subsequent drying of the plastic particles, thereby affecting the drying of the plastic particles.

[0041] When the rotating ring 6 and the water-drying net 4 rotate to be parallel to the workbench 1, the control motor Ⅰ107 drives the gear Ⅰ104 to rotate. Since the gear Ⅰ104 is meshed with the gear ring Ⅰ103, it will drive the gear ring Ⅰ103, the water-drying net 4 and the fixed plate 5 to rotate. At the same time, the control motor Ⅱ108 drives the gear Ⅱ106 to rotate. Since the gear Ⅱ106 is meshed with the gear ring Ⅱ105, it will drive the gear ring Ⅱ105 and the rotating ring 6, and make the rotating ring 6 and the water-drying net 4 rotate synchronously, so as to drive the plastic particles to rotate through the water-drying net 4 and the rotating ring 6. During the rotation of the plastic particles, the water adhered to the plastic particles will be thrown out due to the centrifugal effect, and will eventually be thrown out from the water-drying net 4 to the shell 3, thereby drying the plastic particles. It should be noted that since the water-drying net 4 and the rotating ring 6 are in a circular shape and are parallel to the workbench 1, when the water-drying net 4 and the rotating ring 6 rotate, the plastic particles will be flatly attached to the water-drying net 4, and will not accumulate on one side to affect the drying effect.

[0042] After the water-spinning net 4 and the rotating ring 6 rotate for a period of time, the plastic particles are spun off, so that the time required for subsequent drying is greatly shortened. Then, hot air is input into the rotating shaft 10 through the hot air conveying device connected to the rotating shaft 10, and then the hot air is ejected from the air outlet on the rotating shaft 10, so that the inside of the rotating ring 6 is filled with a large amount of hot air, and then enters between the water-spinning net 4 and the rotating ring 6 through the air outlet groove 6001, so that the plastic particles are heated and dried by the hot air; and in the process of drying the plastic particles, the motor I 107 and the motor II 108 respectively drive the water-spinning net 4 and the rotating ring 6 to rotate, and make the water-spinning net 4 and the rotating ring 6 rotate in opposite directions to each other. During the rotation of the water-throwing net 4 and the rotating ring 6, the extrusion net Ⅰ7 and the extrusion net Ⅱ8 will be driven to rotate respectively. Since the mesh holes of the extrusion net Ⅰ7 and the extrusion net Ⅱ8 are larger than the size of the plastic particles, the plastic particles can pass through the extrusion net Ⅰ7 and the extrusion net Ⅱ8, while the agglomerated plastic particles cannot pass through the extrusion net Ⅰ7 and the extrusion net Ⅱ8, and will be pushed by the extrusion net Ⅰ7 and the extrusion net Ⅱ8 to move, and will eventually be pushed between the extrusion net Ⅰ7 and the extrusion net Ⅱ8. Since the rotating shaft Ⅰ7001 and the rotating shaft Ⅱ8001 are staggered, when the extrusion net Ⅰ7 and the extrusion net Ⅱ8 are in contact, the extrusion net Ⅰ7 and the extrusion net Ⅱ8 squeeze each other, forming a Fig.10 As shown, two adjacent extrusion nets Ⅰ7 rotate towards each other around the rotation axis Ⅰ7001, and two adjacent extrusion nets Ⅱ8 rotate towards each other around the rotation axis Ⅱ8001, so that all the extrusion nets Ⅰ7 and extrusion nets Ⅱ8 avoid each other, so that the rotation of the extrusion nets Ⅰ7 and the extrusion nets Ⅱ8 along the circumferential direction of the shell 3 will not be blocked, and in the process of contact between the extrusion nets Ⅰ7 and the extrusion nets Ⅱ8, the clumped plastic particles will be kneaded, so that the clumped plastic particles are rubbed into separate plastic particles, avoiding the problem in the prior art that some plastic particles are squeezed into clumps and affect the drying of the plastic particles.

[0043] It should be noted that, in the process of drying the plastic particles, the water thrown out will adhere to the inner wall of the shell 3, slide down along the inner wall of the shell 3 to the inner bottom of the shell 3, and then be discharged to the external water storage device through the drainage hole 3001. The water adhering to the upper inner part of the shell 3 will drip downward after accumulating a lot, and then pass through the water-throwing net 4, and return to between the water-throwing net 4 and the rotating ring 6, affecting the effect of drying the plastic particles. Therefore, the upper inner part of the shell 3 is shielded by the sponge belt 202, so that the thrown out water cannot contact the inner wall of the upper part of the shell 3, and the water thrown to the upper inner part of the shell 3 is absorbed by the sponge belt 202. When the plastic particles are dried, the motor III 203 drives the rotating roller 201 to rotate, thereby driving the sponge belt 202 to rotate, and continuously changing the position of the sponge belt 202 located on the upper inner part of the shell 3, so that the sponge belt 202 can continue to absorb more water; thereby avoiding the water adhering to the upper inner part of the shell 3 from dripping downward and affecting the drying effect.

[0044] It should be further noted that a large amount of water vapor will be generated during the drying process of the plastic particles, and the water vapor will condense on the inner wall of the outer shell 3. When the water vapor condenses on the upper inner side of the outer shell 3, it will drip downward, affecting the drying effect of the plastic particles. Therefore, by arranging air outlet holes on the upper side of the outer shell 3, the hot air after drying and the generated water vapor are discharged from the air outlet holes on the upper side of the outer shell 3 and the air holes on the sponge belt 202. In this process, the water vapor in the water vapor can also be absorbed by the sponge belt 202, thereby avoiding the problem of water vapor directly condensing on the inner wall of the upper part of the outer shell 3 and dripping downward.

[0045] After the plastic particles are dried, the motor Ⅰ107 is used to rotate the fixed plate 5 to a state where the rear cover 5001 faces downward, and then the electric push rod Ⅰ101 pushes the rotating plate 102 upward again, so that the support plate 2 and all the parts connected thereto rotate upward, so that the water-spinning net 4 and the rotating ring 6 rotate back to an inclined state with the front higher and the back lower. Then the staff places a plastic particle storage container behind the workbench 1, and then opens the rear cover 5001. Then the plastic particles between the water-spinning net 4 and the rotating ring 6 will slide through the opened cover 5001 to the workbench 1. In the storage container behind the workbench 1, since the water-drying net 4 and the rotating ring 6 are in an inclined state with the front higher and the back lower at this time, the plastic particles between the water-drying net 4 and the rotating ring 6 can slide smoothly to the rear to prevent the plastic particles from remaining between the water-drying net 4 and the rotating ring 6. After the plastic particles between the water-drying net 4 and the rotating ring 6 are discharged, the staff closes the rear cover 5001, then opens the front cover 5001, and then inputs the next batch of plastic particles to be dried, thereby drying the next batch of plastic particles, and repeats this process to complete the drying of the plastic particles.

[0046] Example 2

[0047] On the basis of Example 1, Figure 7-Figure 9 As shown, it also includes an electric push rod II 204 and a squeezing roller 205; the housing 3 is fixedly connected to two electric push rods II 204; the telescopic ends of all the electric push rods II 204 are rotated together and connected to the squeezing roller 205, and the water in the sponge belt 202 is squeezed out through the squeezing roller 205.

[0048] It also includes an electric push rod III 206 and an extrusion block 207; the outer shell 3 is fixedly connected to two electric push rods III 206; the telescopic ends of all the electric push rods III 206 are commonly fixedly connected to the extrusion block 207, and an extrusion portion 20701 is provided on the side of the extrusion block 207 facing the water-throwing net 4, and the shape of the extrusion portion 20701 corresponds to the structure of the water-throwing net 4.

[0049] It also includes a water tank 208. The housing 3 is fixedly connected with the water tank 208, and the water tank 208 is located below the squeezing roller 205. A drainage pipe is provided on the lower side of the water tank 208, and the drainage pipe is connected to an external water storage device.

[0050] The production process of aluminum alloy medium voltage cable includes the following steps:

[0051] Step 1: crushing the insulation layer of the waste cable into plastic particles by a crushing device, and cleaning the plastic particles by a cleaning device;

[0052] Step 2: transporting the cleaned plastic particles to a drying device for aluminum alloy medium voltage cable production for drying;

[0053] Step 3: Feed the dried plastic granules into the extruder to produce the insulation layer of the aluminum alloy medium voltage cable.

[0054] The working steps of the above embodiment are: after the sponge belt 202 absorbs the thrown-out water, in order to prevent the sponge belt 202 from being saturated with water and losing its water absorption capacity, the electric push rod II 204 pushes the squeezing roller 205 to move towards the sponge belt 202 during the drying of the plastic particles, and the squeezing roller 205 cooperates with the rotating roller 201 to squeeze the sponge belt 202, thereby squeezing out the water in the sponge belt 202, and then the squeezed water will flow downward along the outer wall of the shell 3, and then flow into the water storage tank 208, and pass through the drain pipe. It flows into the external water storage device, and at the same time, the sponge belt 202 is driven to rotate by the motor III 203. Since the squeezing roller 205 is in contact with the sponge belt 202 at this time, the squeezing roller 205 will be driven by the sponge belt 202 to rotate, thereby squeezing the other parts of the sponge belt 202, so as to squeeze out the water in the sponge belt 202, so as to avoid the problem that the sponge belt 202 loses its water absorption capacity due to saturation of water after absorbing the thrown water; then after the drying is completed, the electric push rod II 204 pulls the squeezing roller 205 to reset.

[0055] When the plastic particles are spun dry, some of the plastic particles that are in contact with the water-spinning net 4 will be embedded in the mesh of the water-spinning net 4 due to the centrifugal effect, resulting in that when the plastic particles are subsequently discharged, the plastic particles embedded in the mesh of the water-spinning net 4 will not be able to be discharged, resulting in a reduction in the discharge of the plastic particles. After accumulation, the water-spinning net 4 will be blocked, affecting the drying and drying effects. Therefore, the electric push rod III 206 can be used to push the extrusion block 207 to move toward the direction close to the water-spinning net 4, so that the extrusion part 20701 is in contact with the water-spinning net 4. The shape corresponds to the structure of the water-throwing net 4, so the extrusion part 20701 will squeeze the mesh surface of the water-throwing net 4, and the water-throwing net 4 is in a rotating state, so the plastic particles embedded in the mesh holes of the water-throwing net 4 will be pushed into the water-throwing net 4 to avoid the problem that the plastic particles are embedded in the mesh holes of the water-throwing net 4 and block the water-throwing net 4, affecting the spinning and drying effects; and when the plastic particles are discharged, the above steps can also be executed to avoid the residual plastic particles and ensure the discharging effect. After the discharging is completed, the extrusion block 207 is pulled to reset by the electric push rod III 206.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
