Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen for preventing the sticking of plastic particles. Background Technology
[0002] Vibrating screens operate by utilizing the reciprocating rotary vibration generated by the excitation of a vibrator. The combined effect of these vibrations causes the screen surface to produce a complex rotary vibration. Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. Circular vibrating screens perform circular motion and are a multi-layered, high-efficiency new type of vibrating screen. They are characterized by reliable structure, strong excitation force, high screening efficiency, and low vibration noise, and are widely used in product grading in industries such as chemical polymers and energy.
[0003] Because plastic granules are greatly affected by high temperatures, they are prone to sticking together during vibrating screening, leading to an increase in the defect rate of plastic granules. This has a certain impact on the use of vibrating screens, reduces the applicable range of vibrating screening devices, and increases the cost of screening plastic granules. To address this issue, we propose an anti-sticking vibrating screen for plastic granules. Utility Model Content
[0004] The purpose of this invention is to provide a vibrating screen for preventing the sticking of plastic particles, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for preventing the sticking of plastic particles, comprising a base, with one end of several support springs fixedly connected to the top of the base, the other end of the support springs fixedly connected to a mounting base, a lower circular screen fixedly connected to the top of the mounting base, an upper circular screen fixedly connected to the top of the lower circular screen, a dust cover fixedly connected to the top of the upper circular screen, a feed pipe fixedly connected to the center of the top of the dust cover, an annular portion fixedly sleeved on the outside of the feed pipe, a material discharge chute fixedly connected to the inner wall of the feed pipe, and a support rod fixedly sleeved inside the material discharge chute;
[0006] A vibration motor is fixedly installed inside the mounting base. The top of the vibration motor is provided with a lower screen plate that is fixed to the lower circular screen, and the top of the lower screen plate is provided with an upper screen plate that is fixed to the upper circular screen.
[0007] Preferably, a lower discharge hopper is fixedly connected to one side of the bottom of the lower circular screen, and an upper discharge hopper is fixedly connected to one side of the bottom of the upper circular screen, with the upper discharge hopper and the lower discharge hopper being staggered.
[0008] Preferably, the support springs are evenly distributed around the circumference.
[0009] Preferably, the annular portion has a hollow annular cavity inside, and an inlet pipe is fixedly connected to the top of one side of the annular portion, and an outlet pipe is fixedly connected to the bottom.
[0010] Preferably, the material discharge chute has a spiral structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by injecting coolant into the annular part, the coolant is transported by a coolant circulation machine, and the feed pipe transports the plastic particles to be screened. When the plastic particles are transported in the feed pipe, they are guided by the spiral structure of the discharge slide, which slows down the flow rate of the plastic particles and increases the residence time of the plastic particles. In this way, the high temperature of the plastic particles is cooled by the coolant in the annular part, thus avoiding adhesion during screening. Attached Figure Description

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1
[0018] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a vibrating screen for preventing the sticking of plastic particles, including a base 1. The top end of the base 1 is fixedly connected to one end of several support springs 2. The other end of the support springs 2 is fixedly connected to a mounting base 3. The top of the mounting base 3 is fixedly connected to a lower circular screen 4. The top of the lower circular screen 4 is fixedly connected to an upper circular screen 5. The top of the upper circular screen 5 is fixedly connected to a dust cover 6. The top center of the dust cover 6 is fixedly connected to a feed pipe 8. An annular part 7 is fixedly sleeved on the outside of the feed pipe 8. A discharge slide 12 is fixedly connected to the inner wall of the feed pipe 8. A support rod 11 is fixedly sleeved inside the discharge slide 12.
[0019] A vibration motor 15 is fixedly installed inside the mounting base 3. The top of the vibration motor 15 is provided with a lower screen plate 14 fixed to the lower circular screen 4, and the top of the lower screen plate 14 is provided with an upper screen plate 13 fixed to the upper circular screen 5.
[0020] The feed pipe 8 connects to the plastic granule conveying end. The plastic granules to be screened are conveyed through the feed pipe 8 and enter the lower circular screen 4 for screening. At the same time, the coolant circulator is connected to the inlet pipe 71 and outlet pipe 72 through pipelines to provide circulating coolant to the annular cavity in the annular part 7. The high-temperature plastic granules enter the feed pipe 8 and are then guided by the spiral-structured drop slide 12, which slows down the conveying speed of the plastic granules and increases the residence time of the plastic granules. This allows the high-temperature plastic granules to be cooled by the coolant in the annular part 7, preventing them from sticking together during screening. During screening, the vibrating motor 15 is powered on and drives the lower circular screen 4 and the upper circular screen 5 to vibrate, thereby enabling the lower screen plate 14 and the upper screen plate 13 to perform screening. The screened plastic granules are finally discharged and collected through the lower discharge hopper 10 and the upper discharge hopper 9.
[0021] Example 2
[0022] Reference Figure 1-3 This is the second embodiment of the present invention, based on the previous embodiment. Specifically, a lower discharge hopper 10 is fixedly connected to one side of the bottom of the lower circular screen 4, and an upper discharge hopper 9 is fixedly connected to one side of the bottom of the upper circular screen 5. The upper discharge hopper 9 and the lower discharge hopper 10 are staggered. The vibrating motor 15 drives the lower circular screen 4 and the upper circular screen 5 to vibrate, thereby enabling the lower screen plate 14 and the upper screen plate 13 to perform screening. The screened plastic particles are finally discharged and collected through the lower discharge hopper 10 and the upper discharge hopper 9. The staggered arrangement of the upper discharge hopper 9 and the lower discharge hopper 10 facilitates the collection of plastic particles of different sizes screened.
[0023] Specifically, the support springs 2 are evenly distributed around the circumference, and the evenly distributed support springs 2 provide elastic support for the lower circular screen 4 and the upper circular screen 5.
[0024] Specifically, the annular part 7 has a hollow annular cavity inside. An inlet pipe 71 is fixedly connected to the top of one side of the annular part 7, and an outlet pipe 72 is fixedly connected to the bottom. The coolant circulator is connected to the inlet pipe 71 and the outlet pipe 72 through pipelines, thereby providing circulating coolant to the annular cavity inside the annular part 7.
[0025] Specifically, the discharge chute 12 has a spiral structure. The high-temperature plastic particles enter the feed pipe 8 and are then guided by the spiral structure of the discharge chute 12, which slows down the conveying speed of the plastic particles and increases the residence time of the plastic particles. This allows the high-temperature plastic particles to be cooled by the cooling liquid in the annular part 7, thus preventing them from sticking together during screening.
[0026] Example 3
[0027] Reference Figure 1-3 This is the third embodiment of the present invention. Based on the above two embodiments, in use, the feed pipe 8 is connected to the plastic particle conveying end. The plastic particles to be screened are conveyed through the feed pipe 8 and enter the lower circular screen 4 for screening. At the same time, the coolant circulator is connected to the inlet pipe 71 and the outlet pipe 72 through pipelines, thereby providing circulating coolant to the annular cavity in the annular part 7. The high-temperature plastic particles enter the feed pipe 8 and are then guided by the spiral structure of the discharge slide 12, which slows down the conveying speed of the plastic particles and increases the residence time of the plastic particles. This allows the high-temperature plastic particles to be cooled by the coolant in the annular part 7, preventing them from sticking together during screening. During screening, the vibration motor 15 is powered on and drives the lower circular screen 4 and the upper circular screen 5 to vibrate, thereby enabling the lower screen plate 14 and the upper screen plate 13 to perform screening. The screened plastic particles are finally discharged and collected through the lower discharge hopper 10 and the upper discharge hopper 9.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
