Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a device which is convenient for cooling down polyvinyl chloride cable material particles and screening materials. Background Art

[0002] Polyvinyl chloride (PVC) cable material is an important material used in cable processing, with advantages such as good corrosion resistance and good bending performance.

[0003] At present, the production processes of PVC cable materials mainly include the water-cooled cutting process for drawing strips and the hot cutting process on the die surface. Among them, the hot cutting process on the die surface mainly discharges the PVC rubber compound from a twin-screw extruder or a single-screw extruder through a die cake and is directly cut into particles by a cutter. However, the temperature of the relevant particles is as high as about 150°C, which can easily cause the particles to stick together and agglomerate, thereby causing the quality of the particles to deteriorate. At the same time, the relevant particles are generally mixed with debris, which further causes the quality of the particles to deteriorate. Utility Model Content

[0038] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1 This embodiment provides a device for cooling and screening polyvinyl chloride cable material particles, including: a blower 1; an atomizer 2 for communicating with a pelletizer 6; a pipe 3 for communicating with the outlet of the pelletizer 6, one end of the pipe 3 being connected to the blower 1; a buffer ring 4 sleeved on the other end of the pipe 3; a vibrating screening assembly 5 in contact with the buffer ring 4, the other end of the pipe 3 extending into the feed port 515 of the vibrating screening assembly 5.

[0041] Specifically, the pelletizer 6 is used to cut the polyvinyl chloride cable material into particles through a die surface hot cutting process; the atomizer 2 is used to cool the particles to prevent the temperature of the particles from being too high, thereby preventing the particles from sticking and agglomerating, and thus ensuring the quality of the particles. The atomizer 2 may specifically include a number of correspondingly connected hoses 21 and a number of nozzles 22, and the several nozzles 22 are all facing the particles. The number of atomizers 2 is preferably four, and the four atomizers 2 form a square; the blower 1 is used to provide wind power, so that the particles enter the vibrating screen material assembly 5 through the pipe 3, and the temperature range of the wind blown by the blower 1 is 50°C-70°C, so that the blower 1 is also used to dry the moisture remaining on the particles; the pipe 3 is used to connect the pelletizer 6. The outlet of the pelletizer 6 and the feed port 515 of the vibrating screen assembly 5 facilitate the particles in the pelletizer 6 to enter the vibrating screen assembly 5. Since the other end of the pipe 3 extends into the feed port 515 of the vibrating screen assembly 5, when the vibrating screen assembly 5 vibrates, the other end of the pipe 3 and the feed port 515 of the vibrating screen assembly 5 remain connected to prevent particles from overflowing; the vibrating screen assembly 5 is used to screen the particles to facilitate removal of debris in the particles, thereby ensuring the quality of the particles; the buffer ring 4 is used to achieve soft contact between the other end of the pipe 3 and the feed port 515 of the vibrating screen assembly 5 to prevent the vibrating screen assembly 5 from interfering with the pipe 3 during vibration. The material of the buffer ring 4 can be soft materials such as rubber and silicone.

[0042] Further, such as Figure 3 The buffer ring 4 has a through hole 41, and the other end of the pipe 3 passes through the through hole 41. The through hole 41 is connected to the feed port 515 of the vibrating screen assembly 5. Specifically, the through hole 41 is used to pass the other end of the pipe 3, and the diameter of the through hole 41 is preferably smaller than the outer diameter of the pipe 3, so that the buffer ring 4 can be tightly fitted on the outside of the other end of the pipe 3.

[0043] Further, such as Figure 1 The outer diameter of the buffer ring 4 is larger than the diameter of the feed opening 515 of the vibrating screen material assembly 5. Specifically, the outer diameter of the buffer ring 4 is relatively large, and the diameter of the feed opening 515 of the vibrating screen material assembly 5 is relatively small, and the difference between the two diameters is about 60 cm. This facilitates the buffer ring 4 to still cover the feed opening 515 of the vibrating screen material assembly 5 when the vibrating screen material assembly 5 vibrates, further preventing particles from overflowing.

[0044] Further, such as Figure 1The vibrating screening assembly 5 includes: a screening bin 51, a feed port 515 provided in the screening bin 51, and the screening bin 51 is also provided with a discharge port 516; an outer cover 52 connected to the outside of the screening bin 51; a debris channel 53 formed between the screening bin 51 and the outer cover 52; and a vibration unit 54 connected to the screening bin 51. Specifically, when screening materials, the vibration unit 54 drives the screening bin 51 and the outer cover 52 to vibrate. The screening bin 51 is used to screen materials so that particles are discharged from the discharge port 516 and debris is discharged from the debris channel 53. Among them, the feed port 515 facilitates the entry of particles into the screening bin 51. The outer cover 52 cooperates with the screening bin 51 to form a debris channel 53. The debris channel 53 is used to discharge debris. The width of the debris channel 53 is about 20 cm, which means that the screening bin 51 and the outer cover 52 are about 20 cm apart. The vibration unit 54 is used to drive the screening bin 51 and the outer cover 52 to vibrate. The vibration unit 54 may include a vibration motor 541, etc.

[0045] Further, such as Figure 1 The screening bin 51 includes: a bin body 511, a feed port 515 and a discharge port 516 are both provided in the bin body 511; a screen plate 512 and a baffle 513 connected in sequence along the feeding direction, and the screen plate 512 and the baffle 513 are both connected to the bin body 511; a conical cavity 514 is formed between the screen plate 512 and the baffle 513, and the conical cavity 514 is connected to the debris channel 53. Specifically, the silo body 511 is used to support the feed port 515 and the discharge port 516; the screen 512 is used to screen the material so that the particles remain in the silo body 511, allowing the debris to pass through the screen 512 and enter the debris channel 53 along the baffle 513; the conical cavity 514 makes it convenient for the debris to enter the debris channel 53 along the baffle 513 under the action of gravity; the specific number of screens 512 and baffles 513 is not limited, and a number of screens 512 and baffles 513 can be set along the particle feeding direction to ensure that the particles are screened thoroughly.

[0046] Further, such as Figure 1 The screening bin 51 further includes an arc-shaped guide plate 517 connected between the bin body 511 and one end of the screen 512 away from the baffle 513. Specifically, the arc-shaped guide plate 517 is convenient for guiding the particles to prevent them from remaining, and is convenient for changing the direction of the wind.

[0047] Further, such as Figure 1 The vibrating screen assembly 5 further includes a cleaning door 55 movably connected to the outer cover 52. The cleaning door 55 and the screen 512 are correspondingly provided. Specifically, it is convenient for the staff to clean the screen 512 through the cleaning door 55. The cleaning door 55 is preferably provided on the extension line of the screen 512. The number of the cleaning door 55 and the number of the screen 512 are equal, and preferably multiple cleaning doors 55 and screens 512 are provided.

[0048] Further, such as Figure 1The screen 512 is horizontal, and the baffle 513 is inclined. Specifically, the horizontal screen 512 facilitates uniform movement of particles; the inclined baffle 513 facilitates the movement of debris along the baffle 513 under the action of gravity into the debris channel 53; the angle α between the screen 512 and the baffle 513 is preferably 15°.

[0049] Further, such as Figure 1 The vibration unit 54 includes a vibration motor 541; a bracket 542 connected to the output shaft of the vibration motor 541; and an elastic member 543, one end of which is connected to the screening bin 51, and the other end of which is connected to the bracket 542. Specifically, the vibration motor 541 is used to sequentially drive the bracket 542, the elastic member 543, and the screening bin 51 to vibrate, thereby facilitating particle screening. The bracket 542 and the elastic member 543 are correspondingly provided, and preferably, there are multiple of each. The elastic member 543 can be made of spring steel, rubber, or the like.

[0050] Further, such as Figure 1 The vibration screening material assembly 5 further includes a debris collecting bucket 56 communicated with the debris channel 53 . Specifically, the debris collecting bucket 56 is used to collect debris from the debris channel 53 .

[0051] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention.
