[0001] The invention relates to the technical field of toughening agent production, in particular to cooling equipment for processing plastic toughening agent raw materials. Background Art

[0002] With the rapid development of the plastics industry, plastic materials have become an important part of modern manufacturing and are widely used in industries such as automobiles, electronics, packaging, and construction. However, the brittleness and toughness of plastics limit their application in certain usage scenarios, especially the impact performance in low-temperature environments. In addition, the requirement for higher comprehensive properties such as impact resistance, tensile strength, and wear resistance has prompted researchers and manufacturers to continuously seek ways to improve them.

[0003] In the production process of toughening agents, cooling is a key link that directly affects their physical properties and subsequent performance. Traditional cooling equipment mostly uses water cooling or air cooling, which is insufficient in cooling rate and efficiency. Especially for liquid toughening agents, if the cooling is uneven and incomplete, it is very easy to cause problems such as toughening agent aggregation or uneven crystallization, which in turn affects the performance of the toughening agent and the overall quality of the plastic product.

[0006] Furthermore, the upper portion of the cooling tube is connected to a fixed seat, and the stirring device includes a rotating rod, a stirring shaft and an impeller. The rotating rod is rotatably installed on the inner wall of the fixed seat along the width direction of the cooling tube, and the bottom of the stirring shaft is rotatably connected to the bottom end of the inner wall of the cooling tube. The middle outer surface of the rotating rod is sleeved with a first bevel gear, and the top end of the stirring shaft is sleeved with a second bevel gear. The first bevel gear and the second bevel gear are meshingly connected for transmission. The impeller is fixedly sleeved on both sides of the outer surface of the rotating rod, the upper half of the impeller is located in the fixed seat, and the lower half is located inside the cooling tube. The input high-pressure gas drives the impeller to rotate, thereby driving the stirring shaft thereunder to rotate.

[0007] Furthermore, two groups of stirring devices are arranged in the cooling tube, and the two groups of stirring devices are respectively located at the middle side of the front half and the middle side of the rear half of the cooling tube.

[0008] Furthermore, a cooling plate is provided at the bottom of the cooling cylinder, and a continuous S-shaped water passage cavity is opened inside the cooling plate. The water inlet end and the water outlet end of the water passage cavity are respectively connected to the water inlet valve and the second water outlet valve arranged on the outer wall of the cooling cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention has a compact structure, reasonable design and convenient operation. Through the setting of the cooling pipe with an inclined structure, the entering toughening agent will flow in the cooling pipe due to gravity. Compared with the traditional cooling in a cooling chamber, the toughening agent gathers together, resulting in the inability to dissipate internal heat, resulting in insufficient heat exchange and low heat exchange efficiency. The flowing and spread toughening agent in the present invention can effectively increase the heat dissipation area, and utilizes a dual cooling method combining water cooling and air cooling to fully cover the toughening agent for heat absorption, thereby ensuring that the toughening agent is evenly cooled during the cooling process, thereby improving production efficiency and product quality.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a cooling device for processing plastic toughening agent raw materials comprises a cooling pipe 1 and a cooling cylinder 2. The cooling pipe 1 is installed on the upper part of the cooling cylinder 2 at a certain tilt angle and is communicated with the inside of the cooling cylinder 2. The other end of the cooling pipe 1 is connected with a feed pipe 3 for inputting a to-be-cooled object, and the input to-be-cooled object falls from the tilted cooling pipe 1 into the cooling cylinder 2 under the action of gravity. An air valve 4 is arranged at one end of the cooling pipe 1 away from the cooling cylinder 2. The air valve 4 is connected to an external air source for conveying high-pressure gas into the cooling cylinder 2, so as to realize air cooling of the to-be-cooled object. At least one set of stirring devices 5 is arranged inside the cooling pipe 1. The stirring device 5 stirs the to-be-cooled object passing through under the drive of the high-pressure gas. A cooling chamber 6 is arranged along its length direction at the lower part of the cooling pipe 1. One end of the cooling chamber 6 is communicated with a water pump 7, and the other end is provided with a first drain valve 11. The water pump 7 inputs cooling water into the cooling chamber 6, so that the cooling water absorbs the heat of the toughening agent in contact with the inner wall of the cooling tube 1, while the heat of the toughening agent not in contact with the cooling tube 1 is absorbed by the high-pressure gas thereon, thereby achieving an all-round cooling effect.

[0020] See also Figure 2 and Figure 6 As shown, two groups of stirring devices 5 are arranged in the cooling tube 1, and the two groups of stirring devices 5 are respectively located at the middle side of the front half and the middle side of the rear half of the cooling tube 1. The upper part of the cooling tube 1 is connected with a fixed seat 12. The stirring device 5 includes a rotating rod 51, a stirring shaft 52 and an impeller 53. The rotating rod 51 is rotatably installed on the inner wall of the fixed seat 12 along the width direction of the cooling tube 1. The bottom of the stirring shaft 52 is rotatably connected with the bottom end of the inner wall of the cooling tube 2. The middle outer surface of the rotating rod 51 is sleeved with a first bevel gear 54, and the top end of the stirring shaft 52 is sleeved with a second bevel gear 55. The first bevel gear 54 and the second bevel gear 55 are meshed and transmission-connected. Impellers 53 are fixedly sleeved on both sides of the outer surface of the rotating rod 51. The upper half of the impeller 53 is located in the fixed seat 12, and the lower half is located inside the cooling tube 1. The input high-pressure gas drives the impeller 53 to rotate, thereby linking the stirring shaft 52 thereunder to rotate. The function of the high-pressure gas input into the air pump is, firstly, to absorb the heat on the upper part of the toughening agent and cool it down by air; secondly, when the high-pressure gas passes through the impeller 53, it will blow the impeller 53 to rotate, and the rotation of the impeller 53 will drive the rotating rod 51 to rotate, so that the rotating rotating rod 51 drives the stirring shaft 52 thereunder to rotate through the transmission effect of the first bevel gear 54 and the second bevel gear 55, so that the stirring shaft 52 stirs the toughening agent flowing through there, so that the heat inside the toughening agent is dissipated, and it is turned over to change the part in contact with the high-pressure gas and cooling water, so that it can be cooled more evenly; by reasonably utilizing the high-pressure gas to drive the stirring shaft 52 to rotate, no additional power device is required.

[0021] See also Figure 4 and Figure 5 As shown, a cooling plate 21 is provided at the bottom of the cooling cylinder 2, and a continuous S-shaped water passage cavity 22 is provided inside the cooling plate 21. The water inlet end and the water outlet end of the water passage cavity 22 are respectively connected to a water inlet valve 23 and a second water discharge valve 24 provided on the outer wall of the cooling cylinder 2. The water inlet valve 23 is connected to the water pump 7 so as to pass cooling water into the water passage cavity 22 to cool the top surface of the cooling plate 21. The bottom of the cooling cylinder 2 is detachably equipped with a storage cylinder 8, a discharge port 25 is provided on the side of the cooling plate 21 away from the cooling tube 1, and the discharge port 25 is communicated with the storage cylinder 8, a push shaft 26 is rotatably provided in the middle of the top end of the cooling cylinder 2, and the bottom end of the push shaft 26 is rotatably connected to the middle of the cooling plate 21, a motor 27 is provided at the top of the cooling cylinder 2, and the output pipe of the motor 27 extends through and is transmission-connected to the push shaft 26, and a plurality of push plates 28 are evenly spaced and connected to the lower surface of the push shaft 26; When the toughening agent flows out of the cooling pipe 1 and enters the cooling cylinder 2, if there is a part that is not completely cooled, it will continue to be cooled by the cooling plate 21 at the bottom until it is completely cooled; The continuously rotating push shaft 26 and the push plate 28 on the cooling plate 21 will push the toughening agent newly flowing into the cooling cylinder 2 to move toward the discharge port 25. On the one hand, the toughening agent can be kept in motion during the pushing process, so that the heat inside it can be dissipated. In addition, the toughening agent will continuously contact different areas of the cooling plate 21 during the pushing process, avoiding the problem of temperature rise in the area of ​​the cooling plate 21 due to long-term contact with the same area. On the other hand, the completely cooled toughening agent is pushed by the push plate 28 to fall from the discharge port 25 into the storage barrel 8. This design can avoid the toughening agent falling directly from the cooling tube 1 into the storage barrel 8, which will affect the temperature of the previously stored toughening agent and cause the previous toughening agent to reheat and experience material performance degradation, decomposition or thermal degradation.

[0022] See also Figure 2 and Figure 3As shown, a water storage chamber 81 is provided on the side wall of the storage barrel 8, the input end of the water pump 7 is connected to the bottom of the water storage chamber 81 through a pipeline, the first drain valve 11 and the second drain valve 24 are connected to the input end of the water drain radiator 9 through a pipeline, and the output end of the water drain radiator 9 is connected to the upper part of the water storage chamber 81 through a pipeline; The water storage chamber 81 provided in the storage barrel 8 is used to store cooling water for the water pump 7 to draw and input into the cooling chamber 6 and the water passage chamber. On the other hand, the cooling water in the water storage chamber 81 can also play a role in heat insulation and heat preservation, thereby ensuring that the internal temperature of the storage barrel 8 will not be affected by the external environment, so that the toughening agent that has been cooled is stored at a suitable temperature. After absorbing the heat of the toughening agent, the cooling water in the cooling chamber 6 and the water passage chamber 22 flows into the water drain radiator 9, and then flows back into the water storage chamber 81 after the water drain radiator 9 dissipates heat and cools the water, so as to realize water circulation cooling without the participation of external water flow, thereby achieving water-saving effect.

[0023] See also Figure 2 As shown, a discharge pipe 82 is provided in the middle of the bottom end of the storage barrel 8, and a discharge valve is provided on the discharge pipe 82. The bottom surface inside the storage barrel 8 is a structure with the edge inclined toward the middle. A hot gas outlet 29 is provided at the top of the cooling barrel 2 near the cooling pipe 1, and the hot gas outlet 29 is connected to an external exhaust gas treatment device. The design of the discharge pipe 82 allows the staff to directly open the discharge valve to discharge the cooled toughening agent, and the bottom surface of the storage barrel 8 is inclined, on the one hand, to facilitate the outflow of the toughening agent, and on the other hand, Figure 2 As shown, the volume of the water storage chamber 81 can be increased to store more cooling water; When the high-pressure gas input into the air pump passes through the cooling pipe 1 and cools the toughening agent by air cooling, the high-pressure gas absorbs the heat of the toughening agent, thereby increasing its own temperature. At the same time, it also takes away the harmful gases released by the toughening agent due to the high temperature. Finally, the high-temperature harmful gases leave the cooling pipe 1 and are discharged from the hot gas outlet 29, and are passed into the exhaust gas treatment device to recover the heat in the gas, and then the gas is purified and safely discharged.
