Description

Technical Field

[0001] This utility model relates to the technical field of flame retardant masterbatch processing equipment, specifically a rotating separating screen for flame retardant masterbatch production. Background Technology

[0002] Flame retardant masterbatch, also known as flame retardant masterbatch or fireproof masterbatch, is a functional additive material designed to improve the fire resistance of plastic, rubber and other products. It is made by combining bromine-based, halogen-based and other flame retardants with a carrier, modifying them and then extruding and granulating them. Its core function is to achieve flame retardancy. The covering mechanism includes heat absorption and inhibition of chain reaction. It has the characteristics of good dispersibility, high flame retardant efficiency and little impact on the mechanical properties of materials. It can replace traditional powdered flame retardants.

[0003] Flame retardant masterbatch processing involves many steps. After cutting and shaping, it needs to be screened using a screening device. Shaftless drum screens have significant advantages in flame retardant masterbatch screening, such as avoiding entanglement, improving screening efficiency, increasing throughput, reducing maintenance costs, and strong adaptability. They can efficiently and stably complete the grading task of flame retardant masterbatch.

[0004] However, in practical applications, although shaftless drum screens are highly efficient, their screening holes are prone to clogging. This requires manual tapping of the drum screen during use to dislodge the flame retardant masterbatch blocking the holes. This not only affects the work efficiency of the staff but also easily damages the drum screen. Secondly, the transmission of drum screens mostly uses friction wheels, but drum screens do not have radial limiting functions. As the friction coefficient between the drum screen and the friction wheel naturally decreases, the transmission efficiency continues to decline, thus affecting the screening quality of flame retardant masterbatch. Utility Model Content

[0005] This utility model provides a rotary separator for the production of flame retardant masterbatch. By adjusting the vibration of the frame and the screening cylinder through a vibrating component, it can clean the flame retardant masterbatch clogging inside the screening holes. Furthermore, by using a limiting frame and a limiting rod, it can not only limit the radial movement of the screening cylinder, improving its stability under vibration, but also increase the friction between it and the friction wheel, further promoting the screening efficiency of the screening cylinder for flame retardant masterbatch. This solves the problems mentioned in the background art of easy clogging and decreased rotation efficiency of the screening cylinder during use.

[0006] This utility model provides the following technical solution:

[0007] A rotary separator for flame-retardant masterbatch production includes a frame and a friction wheel rotatably connected to the frame via a transmission rod. The friction wheel has a screening cylinder abutting its surface. A drive unit is mounted on the frame, and when the drive unit operates, the friction wheel tends to drive the screening cylinder to rotate. A limiting frame is fixedly connected to the frame, and a limiting rod abutting the surface of the screening cylinder is rotatably connected within the limiting frame. A base is rotatably connected to the bottom of the frame, and a vibrator for adjusting the vibration of the screening cylinder is mounted on the base.

[0008] As a preferred embodiment of this utility model, the driving component includes a drive motor fixedly mounted on the frame, a reducer fixedly connected to the output end of the drive motor, and the output end of the reducer fixedly connected to the transmission rod.

[0009] As a preferred embodiment of this utility model, the vibrating component includes: a servo motor, fixedly mounted on the base, wherein a cam is fixedly connected to the output end of the servo motor, the surface of the cam abuts against the bottom of the frame, and the end of the cam away from the servo motor is rotatably connected to the base; and a spring disposed on the base, the two ends of the spring being fixedly connected to the base and the frame respectively.

[0010] As a preferred embodiment of this utility model, a feed hopper is fixedly connected to the frame, the feed hopper is located at the feed end of the screening cylinder, and the discharge port of the feed hopper has a tendency to shrink inward.

[0011] As a preferred embodiment of this utility model, at least two baffles are fixedly connected inside the screening cylinder and are arranged sequentially along the axial direction of the screening cylinder. The shape of the baffles is spiral.

[0012] As a preferred embodiment of this utility model, the mounting surface of the frame is inclined at an angle of 15 degrees.

[0013] As a preferred embodiment of this utility model, the number of limiting rods is five, and the five limiting rods are distributed in a ring around the outer surface of the screening cylinder within the limiting frame.

[0014] As a preferred embodiment of this utility model, a collection shell is fixedly installed on the frame, and the collection shell is located at the lower end of the screening cylinder.

[0015] Compared with the prior art, this utility model provides a rotary separator for flame retardant masterbatch production, which has the following advantages:

[0016] 1. In this rotating separator screen for flame retardant masterbatch production, the driving force of the drive motor is transmitted to the reducer through the setting of the drive component. The reducer reduces the transmission speed, so that the transmission rod drives the friction wheel to rotate at a uniform speed, thereby ensuring that the screen cylinder can always maintain a stable state during the operation.

[0017] 2. In this rotary separator for flame retardant masterbatch production, the servo motor output drives the cam to rotate vertically via the vibrating components. When the cam rotates vertically, it presses against one end of the frame, causing the screening cylinder to move upward. When the cam rotates horizontally, the frame is pulled downward by the reaction force of the spring to reset. As the cam continues to rotate, the frame repeatedly moves up and down, generating continuous vibration. This vibration force is transmitted to the screening cylinder, effectively cleaning the flame retardant masterbatch clogging the screening holes, thereby improving the screening quality of the flame retardant masterbatch.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-6A rotary separator for flame-retardant masterbatch production includes a frame 1 with an inclined mounting surface at a 15-degree angle. This inclined mounting surface effectively guides the flame-retardant masterbatch within the screening cylinder 3, further improving screening efficiency. The separator also includes friction wheels 2, rotatably connected to the frame 1 via two transmission rods. Each transmission rod has two friction wheels 2 fixedly mounted on it. A screening cylinder 3, with annular rubber pads mounted on the screening cylinder 3, abuts against the friction wheels 2. A drive mechanism is mounted on the frame 1. When the drive mechanism operates, the friction wheels 2 tend to drive the screening cylinder 3 to rotate, thus improving the internal flame-retardant masterbatch. Flame retardant masterbatch screening; a limiting frame 5 is fixedly connected to the frame 1. The limiting frame 5 is U-shaped. A limiting rod 6 is rotatably connected inside the limiting frame 5, which abuts against the surface of the screening cylinder 3. There are five limiting rods 6, and the five limiting rods 6 are distributed in a ring along the outer surface of the screening cylinder 3 inside the limiting frame 5. A base 8 is rotatably connected to the bottom of the frame 1. A vibrating element is provided on the base 8 to adjust the vibration of the screening cylinder 3. When the vibrating element is working, the base 8 drives the screening cylinder 3 to vibrate, which can cause the flame retardant masterbatch blocking inside to fall off naturally, thereby cleaning and maintaining the screening cylinder 3. A collection shell is fixedly installed on the frame 1, and the collection shell is located at the lower end of the screening cylinder 3 for collecting smaller flame retardant masterbatch.

[0031] Specifically, the friction wheel 2 is driven to rotate by the driving component, causing the screening cylinder 3 to rotate axially, which enables the screening of the flame retardant masterbatch inside. At the same time, during the screening process, the limiting rod 6 is used to limit the radial movement of the screening cylinder 3, which increases its contact with the friction wheel 2 and ensures the stability of the transmission. Furthermore, the vibration of the screening cylinder 3 is adjusted by the vibrating component, which allows the flame retardant masterbatch blocking the inside to fall off naturally, effectively clearing the screen and further improving the screening efficiency and quality of the screening cylinder 3.

[0032] The driving component includes a drive motor 4 fixedly mounted on the frame 1. A reducer 41 is fixedly connected to the output end of the drive motor 4. The output end of the reducer 41 is fixedly connected to one of the transmission rods.

[0033] Specifically, through the configuration of the driving components, the driving force of the drive motor 4 is transmitted to the reducer 41, and the reducer 41 reduces the transmission speed, so that the transmission rod drives the friction wheel 2 to rotate at a uniform speed, thereby ensuring that the screening cylinder 3 can always maintain a stable state during the operation.

[0034] The vibrating component includes: a servo motor 9, which is fixedly mounted on the base 8. The output end of the servo motor 9 is fixedly connected to a cam 91. The surface of the cam 91 abuts against the bottom of the frame 1. The end of the cam 91 away from the servo motor 9 is rotatably connected to the base 8. A spring 92 is set on the base 8. The two ends of the spring 92 are fixedly connected to the base 8 and the frame 1 respectively.

[0035] Specifically, through the setting of the vibrating component, when the output end of the servo motor 9 drives the cam 91 to rotate vertically, the cam 91 squeezes one end of the frame 1, causing it to drive the screening cylinder 3 to move upward. When the cam 91 rotates horizontally, under the reaction force of the spring 92, it pulls the frame 1 downward to achieve reset. As the cam 91 continues to rotate, the frame 1 continuously repeats the above-mentioned up-and-down movement process, thereby generating continuous vibration. After this vibration force is transmitted to the screening cylinder 3, it can effectively clean the flame retardant masterbatch blocking the screening holes, thereby improving the screening quality of the flame retardant masterbatch.

[0036] A feed hopper is fixedly connected to the frame 1. The feed hopper is located at the feed end of the screening cylinder 3, and the discharge port of the feed hopper has a tendency to shrink inward.

[0037] Specifically, the feeding hopper facilitates the addition of flame-retardant masterbatch to the inside of the screening cylinder 3 by staff, thereby further improving the processing efficiency of the screening cylinder 3.

[0038] At least two baffles 7 are fixedly connected inside the screening cylinder 3, preferably four, and are arranged sequentially along the axis of the screening cylinder 3. The shape of the baffles 7 is spiral.

[0039] Specifically, by setting up the baffle 7, the transfer efficiency of flame retardant masterbatch inside the screening cylinder 3 can be reduced, thereby improving the screening quality of the screening cylinder 3.

[0040] In this invention, the flame retardant masterbatch to be screened is poured into the screening cylinder 3. Then, the drive motor 4 is started by an external control switch. The output end of the drive motor 4 starts to rotate and drives the reducer 41 connected to it to operate. The output end of the reducer 41 further drives the transmission rod to rotate. During the rotation of the transmission rod, the friction wheel 2 rotates synchronously. The rotation of the friction wheel 2 directly drives the screening cylinder 3 to rotate. During the rotation of the screening cylinder 3, the flame retardant masterbatch inside it moves slowly along the inner wall of the screening cylinder 3 under the action of gravity. At this time, the smaller flame retardant masterbatch can be smoothly discharged through the screening holes on the screening cylinder 3, thereby achieving effective screening of the flame retardant masterbatch.

[0041] While the screening operation is underway, the operator can start the servo motor 9 via an external control switch. When the output end of the servo motor 9 rotates, it drives the cam 91 to rotate as well. When the cam 91 rotates to the vertical position, it will drive one end of the frame 1 to move upward. During this process, the frame 1 will stretch the spring 92. When the cam 91 rotates to the horizontal position, the spring 92, under the action of the reaction force, pulls one end of the frame 1 downward to achieve a reset. As the cam 91 continues to rotate, the frame 1 will continuously repeat the above up-and-down movement process, thereby generating continuous vibration. This vibration force is transmitted to the screening cylinder 3, which can effectively clean the flame retardant masterbatch that is blocked inside the screening holes, avoid the screening effect caused by the blockage of the screening holes, and thus significantly improve the screening quality of the flame retardant masterbatch.

[0042] In addition, when the frame 1 drives the screening cylinder 3 to vibrate, the limiting frame 5 and the limiting rod 6 play an important radial limiting role. On the one hand, they can effectively prevent the screening cylinder 3 from being damaged by vibration and extend the service life of the equipment; on the other hand, they can ensure that the screening cylinder 3 always remains in contact with the friction wheel 2, thereby ensuring the stable rotation efficiency of the screening cylinder 3 and ensuring the smooth progress of the screening operation.

[0043] It should be noted that components not described in detail in this article are existing technologies.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
