Description

Technical Field

[0001] This utility model relates to the field of plastic granule manufacturing technology, and in particular to a vertical vibrating screen for heat dissipation of plastic granules. Background Technology

[0002] Vertical vibrating screens (or vertical vibrating elevators) generally use two vibrating motors to excite the conveyor tower, allowing granular materials to be vertically conveyed on the spiral conveyor plate on the conveyor platform. The spiral conveyor plate is made of metal, and the material has a certain heat dissipation and cooling effect when it comes into contact with the spiral conveyor plate, but the heat dissipation effect is relatively general. Therefore, the main function of vertical vibrating elevators that do not have water cooling or air cooling systems is to lift and convey.

[0003] Vertical vibratory elevators that require cooling and heat dissipation are equipped with water-cooling and / or air-cooling systems, such as the vertical vibratory elevator shown in prior art CN206939699U. The water-cooling system involves setting a sandwich structure inside the spiral conveyor plate, allowing cooling water to circulate within the sandwich of the spiral conveyor plate, carrying away the heat of the spiral conveyor plate and improving heat dissipation efficiency. However, the processing of setting a sandwich structure inside the spiral conveyor plate is relatively difficult, with high processing costs and high sealing requirements. In addition, the spiral conveyor plate vibrates continuously during operation, which can easily cause the structure to crack over time. If cooling water leakage occurs, it will affect the material.

[0004] The air-cooled system has air holes on the central tube of the spiral conveyor plate. Air is supplied to the central tube by an air supply device, and the central tube blows air onto the material on the spiral conveyor plate through the air holes to improve heat dissipation efficiency. However, when applied to the lifting, conveying and heat dissipation of plastic granules, it will spread the odor and powder of the plastic granules. The odor produced by the high-temperature plastic granules is strong and may contain volatile organic compounds that are harmful to the human body, which will cause serious pollution to the production site. Therefore, it is necessary to improve it. Utility Model Content

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] refer to Figure 1-3 An embodiment of this utility model shows a vertical vibrating screen for heat dissipation of plastic particles, including a base 1, a base 2, a conveying tower 3, and an oscillating motor 4.

[0036] The base 1 is fixedly installed, for example, on the ground of the production site, and the base 1 is used to provide stable support; the base 2 is installed on the base 1, and a vibration damping spring 11 is provided between the base 2 and the base 1. The vibration damping spring 11 can prevent the vibration of the base 2 from being transmitted to the base 1; the oscillation motor 4 is installed on the base 2. Generally, two oscillation motors 4 are provided, and the two oscillation motors 4 cause the base 2 to vibrate.

[0037] The conveying tower 3 is mounted on the base 2. The conveying tower 3 includes a vertically arranged central tube assembly 31, and a first spiral conveying plate 32 is arranged on the outer side of the central tube assembly 31. The central tube assembly 31 includes an outer tube 311 and an inner tube 312 disposed inside the outer tube 311. An exhaust duct 313 is formed between the outer tube 311 and the inner tube 312. An air inlet 3111 is opened on the side wall of the outer tube 311, and the air inlet 3111 communicates with the exhaust duct 313. A connecting part for connecting the exhaust device 100 is provided at the top of the central tube assembly 31. The design of the central tube assembly 31 with an outer tube 311 and an inner tube 312 can improve its structural strength.

[0038] The oscillating motor 4 causes the base 2 to vibrate, and the base 2 vibrates together with the conveying tower 3. The first spiral conveying plate 32 on the conveying tower 3 lifts the plastic particles upward. Conventionally, the top of the first spiral conveying plate 32 has an output end (not marked in the figure), and the plastic particles eventually leave from the output end of the first spiral conveying plate 32. During the above-mentioned conveying and lifting process, such as Figure 2As shown, the top of the central tube assembly 31 is connected to an external air extraction device 100 via an air extraction pipe 200. The air extraction device 100 extracts air, causing the air outside the conveying tower 3 to accelerate into the first spiral conveying plate 32 and enter the exhaust duct 313 through the air inlet 3111. The flowing air carries away the heat, odor, and powder of the plastic particles. In this vertical vibrating screen used for heat dissipation of plastic particles, heat dissipation of plastic particles is achieved by air extraction. This not only improves the heat dissipation effect but also absorbs the odor and powder carried by the plastic particles, which to a certain extent inhibits the diffusion of odor and powder from the plastic particles and helps maintain the breathing environment of the production site.

[0039] Compared to the air-cooled structure in the prior art, the vertical vibrating screen for heat dissipation of plastic particles can suppress the diffusion of odor and powder from the plastic particles; compared to the water-cooled structure in the prior art, the vertical vibrating screen for heat dissipation of plastic particles does not require processing of a sandwich structure and there is no risk of cooling water leakage affecting the materials; of course, in cases where heat dissipation requirements are higher, the vertical vibrating screen for heat dissipation of plastic particles in this application can also consider adding a water-cooling system.

[0040] In some embodiments, such as Figure 3 As shown, the connection at the top of the central tube assembly 31 is a flange connection plate 3112 disposed at the top of the outer tube 311. The extraction pipe 200 on the extraction device 100 forms a sealed flange connection with the flange connection plate 3112 at the top of the outer tube 311.

[0041] In some embodiments, a second spiral conveying plate 314 is provided between the outer tube 311 and the inner tube 312; a vertically arranged channel 21 is formed in the base 2, the top end of the channel 21 is connected to the exhaust duct 313, and the bottom end of the channel 21 is provided with an end cap 22.

[0042] The outer side of the second spiral conveyor plate 314 is welded to the inner wall of the outer tube 311, and the inner side of the second spiral conveyor plate 314 is welded to the outer wall of the inner tube 312. The second spiral conveyor plate 314 can increase the connection stability between the outer tube 311 and the inner tube 312. In addition, the second spiral conveyor plate 314 can also block materials that accidentally enter the exhaust duct 313, preventing them from being sucked away. Specifically, theoretically, the aperture of the air inlet 3111 should be smaller than the particle size of the material (plastic particles) to prevent plastic particles from passing through the air inlet 3111. However, some plastic particles may have a particle size smaller than the design range. These substandard particles may pass through the air inlet 3111 and enter the exhaust duct 313. The second spiral conveyor plate 314 can prevent these substandard particles from entering the exhaust device 100. These substandard particles will fall downwards and leave through the channel 21 of the base 2.

[0043] The end cap 22 is sealed at the bottom of the channel 21, and the end cap 22 can be a rubber plug. When evacuating, the end cap 22 is sealed on the channel 21 to make the evacuation device 100 stronger in evacuating the air inlet 3111. After production is completed, the end cap 22 can be opened to allow defective particles in the channel 21 to fall out.

[0044] Preferably, a receiving tray 5 is provided below the base 2 to collect defective particles falling from the channel 21.

[0045] Specifically, to further prevent plastic particles from entering the exhaust duct 313 through the air inlet 3111, the above solution includes, for example... Figure 3 As shown, there is a height difference d between the air inlet 3111 and the top surface of the first spiral conveyor plate 32, and the height difference d is at least 3cm.

[0046] Specifically, to further ensure that plastic particles do not enter the exhaust device, a mesh screen (not shown) is provided at the top of the exhaust duct 313. The mesh screen can be installed inside the exhaust duct 313 or inside the exhaust pipe 200.

[0047] The above-mentioned solutions are specific, such as Figure 1 As shown, a feeding tray 33 is provided below the conveying tower 3, and the feeding tray 33 is located between the conveying tower 3 and the base 2. In use, plastic granules can be added to the feeding tray 33, and the plastic granules in the feeding tray 33 will enter the input end below the first spiral conveyor plate 32.

[0048] In some embodiments, to facilitate the hoisting of the conveyor tower 3, such as Figure 3 As shown, the top of the inner tube 312 is provided with a lifting ring 3121.

[0049] In summary, this application provides a vertical vibrating screen for heat dissipation of plastic granules. This vertical vibrating screen dissipates heat from the plastic granules by means of air extraction, which not only improves the heat dissipation effect, but also removes the odor and powder carried by the plastic granules, thereby inhibiting the diffusion of odor and powder from the plastic granules to a certain extent and helping to maintain the breathing environment of the production site.

[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
