Abstract
Description
Technical Field
[0001] The utility model relates to the field of straw masterbatch production, in particular to a cooling device used for straw masterbatch production. Background Art
[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.
[0003] As a pigment material, straw masterbatch is primarily used to provide a variety of substrates such as plastics, rubber, textiles, etc. with rich colors and texture designs. Adding masterbatch during the manufacturing process can make the product obtain the desired color during the molding process, and the color is uniform and stable. Using straw masterbatch for coloring can significantly improve the appearance quality of the product and help ensure the consistency and quality of the product. Straw masterbatch usually does not contain harmful substances, meets environmental protection requirements, and is harmless to the human body and the environment.
[0004] The production process of straw masterbatch and traditional masterbatch is to mix the raw materials evenly according to the ratio, extrude the raw materials from the extruder head through a screw extruder, and cool the strip-shaped masterbatch strips after extrusion. For the cooling process of straw masterbatch and traditional masterbatch, the traditional masterbatch directly enters the cooling pool for water cooling, and then the masterbatch strips are air-dried. However, since the straw masterbatch contains straw components, it will expand when it comes into contact with water, thereby affecting the product performance. For this, the existing straw masterbatch cooling process is to arrange multiple fans at intervals in the production line to continuously blow air to the straw masterbatch strips, thereby cooling the straw masterbatch strips. However, for this method, the drying efficiency is low and it occupies a lot of resources. Therefore, it is necessary to improve the above cooling method. Utility Model Content
[0005] The purpose of the utility model is to provide a cooling device for the production of straw masterbatch, which is used in a straw masterbatch production line to cool the straw masterbatch strips. It can reasonably distribute the required air volume according to different positions in the production line, so that the cooling of the straw masterbatch strips is more reasonable, and the overall cooling of the straw masterbatch strips in the production line can be achieved by a fan.
[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0007] A cooling device for straw masterbatch production comprises a blower, an air inlet pipeline connected to the blower at one end, and a plurality of air outlet pipelines arranged in an array on the air inlet pipeline; the other end of the air inlet pipeline is closed, and the diameter of the air inlet pipeline or the air outlet pipeline is controlled so that the air volume of each air outlet pipeline corresponds to the wind speed required for cooling the straw masterbatch strips.
[0008] The air inlet pipeline is provided with multiple sections, and the diameters of the multiple air inlet pipelines gradually increase along the conveying direction of the production line.
[0009] The diameters of the multiple air outlet pipes gradually increase along the conveying direction of the production line.

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0019] The utility model is a cooling device for straw masterbatch production, as shown in the accompanying drawings of the specification. Figure 1 As shown, the main structure includes a blower 1, an air inlet pipeline 2 connected to the blower 1 at one end, and a plurality of air outlet pipelines 3 arranged in an array on the air inlet pipeline 2;
[0020] The blower 1 is a Roots blower, which is mostly used in industrial production. Compared with fans, it has stronger wind force and faster wind speed, and can provide sufficient air volume. The other end of the air inlet duct 2 is closed, so that the wind blown in through the blower 1 flows out from the air outlet duct 3 after entering the air inlet duct 2. For the straw masterbatch production line, when the straw masterbatch strips are just extruded from the head of the screw extruder, they are in a form similar to a viscous fluid, so the straw masterbatch strips at this time have not formed a solid, but are in a semi-fluid state. For this reason, the straw masterbatch strips need to be quickly cooled to prevent the straw masterbatch strips from causing changes in cross-sectional shape during the transportation process of the production line, resulting in uneven particle size of the straw masterbatch. Because for the masterbatch, the masterbatch strips need to be pelletized after cooling, and the masterbatch can be packaged after the particle size of the masterbatch is screened. Therefore, excessive deformation of the cross-sectional shape of the straw masterbatch strip will affect the screening of the masterbatch and increase the defective rate. Therefore, the corresponding straw masterbatch strip needs to be quickly cooled down when it is just extruded from the die head by the screw extruder. Correspondingly, the air volume here needs to be larger and decreases in sequence along the conveying direction of the production line. It can be concluded that the air volume of each air outlet duct 3 needs to correspond to the wind speed required for cooling the straw masterbatch strip.
[0021] According to the formula flow rate = flow rate / pipe cross-sectional area, it can be concluded that the smaller the pipe diameter, the faster the flow rate. Therefore, by controlling the pipe diameter of the air inlet pipe 2 or the air outlet pipe 3, the air volume of each air outlet pipe 3 corresponds to the wind speed required for cooling the straw masterbatch strips.
[0022] As shown in the attached figure of the instruction manual Figure 1 and Figure 2 As shown, when the diameter of the air inlet pipeline 2 is controlled, the air inlet pipeline 2 is provided with multiple sections, and the diameters of the multiple air inlet pipelines 2 gradually increase along the conveying direction of the production line. The air inlet pipeline 2 is set to multiple sections, and the number of sections of the air inlet pipeline 2 is the same as the position where the air blowing needs to be set, and the diameters of each section of the air inlet pipeline 2 are different and increase. At this time, since the diameter of the air outlet pipeline 3 is gradually increasing, the wind speed of each section of the air outlet pipeline 3 is gradually decreasing, so that the airflow flowing out of the air outlet pipeline 3 corresponds to the situation required by the straw masterbatch production line, and the resources in the production line can be better allocated, so that the cooling process of the straw masterbatch strips is more reasonable during the transportation of the production line.
[0023] As shown in the attached figure of the instruction manual Figure 3 As shown, when the diameter of the air outlet pipeline 3 is controlled, the diameters of the multiple air outlet pipelines 3 gradually increase along the conveying direction of the production line. At this time, the diameter of the air inlet pipeline 2 is fixed, and the diameter of each air outlet pipeline 3 gradually increases along the conveying direction of the production line. Similar to the above, this makes the airflow flowing out of the air outlet pipeline 3 change due to the influence of the diameter of the air outlet pipeline 3, and the diameter of the air outlet pipeline 3 is also inversely proportional to the flow rate. The distribution of multiple air outlet pipelines 3 with different diameters is adapted to the wind speed required for the production line to transport the straw masterbatch strands for cooling.
[0024] For the straw masterbatch strip production line, since the straw masterbatch strips are extruded from the head of the screw extruder in multiple strips and distributed in an array, in order to make the air volume and wind speed blowing to multiple straw masterbatch strips in the production line uniform, the outlet duct 3 has a duckbill shape. The duckbill flat mouth is set to make the air volume more concentrated and evenly distributed, which is beneficial to the uniform cooling of the straw masterbatch strips and the stable quality of the straw masterbatch.
[0025] In summary, this device is used in the straw masterbatch production line to cool the straw masterbatch strips. It can reasonably distribute the required air volume according to different positions in the production line, making the cooling of the straw masterbatch strips more reasonable, and the overall cooling of the straw masterbatch strips in the production line can be achieved through one fan.
