Detailed Description
The following description of the technical solutions in the embodiments of the present invention is made clearly and completely with reference to the accompanying drawings.
Example 1
As shown in the figure, a casting head having a dual-cavity structure comprises a casting head body 1, wherein the casting head body 1 mainly aims to uniformly distribute and extrude a melt added into a strand casting head into strands, and the casting head body 1 comprises a casting head shell 3 and a casting belt unit 4;
The casting head shell 3 is internally provided with a cavity, and in order to avoid the melt solidification or the melt performance change caused by the temperature drop of the melt when the melt passes through the casting head due to the higher temperature (about 300 degrees), the casting head body is designed into an integral shell consisting of an inner cavity and an outer cavity, namely the cavity comprises an inner cavity 301 for uniformly distributing the melt and an outer cavity 302 for circulating a heating medium, the inner cavity 301 is divided into two melt channels, the melt enters the inner cavity 301 through an inlet of a melt pipe 303 and is distributed to a distributing plate of a casting belt unit and a casting belt plate to form strands through the two melt channels; the outer cavity 302 is communicated with the heating medium inlet pipeline 201 and the heating medium outlet pipeline 202, the position of the heating medium outlet pipeline 202 is higher than that of the heating medium inlet pipeline 201, when the heating medium is introduced, the heating medium is low in and high out, the inner cavity of the casting belt head is guaranteed to have enough temperature, the heating medium is heating medium or heat conducting oil, and the whole shell formed by the inner cavity and the outer cavity is designed to be pre-distributed in the inner cavity before entering the casting belt unit for distribution, so that distribution is more uniform. Meanwhile, the processing of the double-cavity structure is easier to realize, the roughness can be higher, and the extrusion of the melt is facilitated.
Further, the larger the melt tube design, the slower the flow rate due to the higher melt viscosity, to ensure adequate production of the cast strip head.
Further, a preheating chamber 2 for preheating new casting belt units is arranged on the left side of the casting belt head main body 1, a supporting plate for placing the casting belt units is arranged in the preheating chamber, a sliding guide rail I is arranged on the supporting plate, a heating medium inlet pipeline 201 is arranged on the preheating chamber 2, and a heating medium outlet pipeline 202 is arranged at the top of the outer cavity 302;
The right side of the casting belt head main body 1 is also provided with a guiding-out frame 7 for placing the casting belt unit 4, the bottom end surface of the guiding-out frame 7 is provided with a sliding guide rail III, the bottom of the inner cavity of the casting belt head shell 3 can be also provided with a sliding guide rail II, the positions of the sliding guide rail I, the sliding guide rail II and the sliding guide rail III are sequentially lowered, and the casting belt unit 4 is conveniently pushed onto the sliding guide rail II from the sliding guide rail I in sequence and then pushed onto the sliding guide rail III;
The method comprises the following steps: when the cast strip units 4 need to be replaced, new cast strip units 4 can be placed in the preheating chamber 2 in advance for preheating, the used cast strip units 4 are removed and pushed out by the right guiding-out frame 7, the preheated cast strip units are replaced, and the cast strip units 4 are pushed into the sliding guide rails II from the sliding guide rails I of the preheating chamber, so that the replacement of the cast strip units is completed. The preheating chamber 2 and the guiding-out frame 7 are integrated on the casting belt head to mainly meet the requirements of customers for reducing cost and increasing safety, because the casting belt head needs to be heated by a heating medium, a preheating cavity is welded beside the cavity of the casting belt head, the cost is relatively low, and when the casting belt unit is replaced, the operation distance is short, and the operation is more convenient and safe. Otherwise the customer purchases the oven. The purpose of the lead-out rack 7 is then for the customer to place the replaced cast strip unit on the lead-out rack first and take it off after it has cooled. Thus avoiding scalding personnel.
A plurality of guide plates 5 are horizontally arranged in the outer cavity 302, one ends of the guide plates 5 are connected with the inner wall of the outer cavity 302, gaps 6 are arranged between the other ends of the guide plates 5 and the inner wall of the outer cavity 302, and the directions of the gaps 6 between the upper adjacent and the lower adjacent guide plates are opposite. The number of the guide plates 5 is 4, and the guide plates 5 are arranged to prolong the flow of the heating medium, so that the melt is heated fully and uniformly in the cavity.
Further, in order not to cause heat dissipation, a thermal insulation tray 8 is correspondingly arranged outside the cast strip head shell 3, and the thermal insulation tray 8 is filled with a thermal insulation material, such as thermal insulation mud for thermal insulation.
Further, the belt casting unit 4 comprises a distribution chamber, a distribution plate and a belt casting plate 9,
Because the melt has certain hardness, the pore diameter of the cast strip hole is continuously worn in the extrusion process, and the pore diameter becomes larger after the time is longer, so that the particle becomes thicker. So in order to extend the life of the cast strip, the cast strip hole 901 in the bottom of the cast strip 9 is provided with a cemented carbide sleeve 902, said cemented carbide sleeve 902 being welded to the cast strip hole 901 by means of a tightening ring 903, the cast strip aperture being designed as a cemented carbide inlaid structure in order to increase its wear resistance.
Further, a scraping device is further arranged on the casting belt head main body 1, the scraping device comprises a scraping plate 10, the scraping plate 10 scrapes the casting belt plate 9 of the casting belt unit through cylinder driving, the scraping device is designed into an automatic transmission mechanism, and the scraping device mainly acts on the cylinder through an electromagnetic valve of the air path control box 11, so that the scraping plate 10 moves at a high speed to scrape the casting belt plate. At the same time, the scraper blade 10 is arranged on the casting belt head, and the gap between the scraper blade 10 and the casting belt plate 9 is not changed due to the expansion of the casting belt head, so that a better scraping effect can be achieved. The die scraping device is designed to be interlocked with the granulator, and the die scraping device scrapes the cast strip plate every few seconds (can be arranged) before material receiving is needed, so that the cast strip head discharging and guide groove material receiving can be guaranteed to reach a better state, melt can not be accumulated on the starting head due to too early scraping, and scraping can not be caused to collide with the starting head due to too late scraping. When the large-yield die is driven, the die is better to scrape, so that the grain cutting cannot be influenced. The granulating equipment without the die scraping device can only be started in low yield, and the yield is improved after the granulating equipment is stabilized, so that the productivity of customers is affected, and the performances of materials are possibly affected due to the fact that the time of a melt in a polymerization kettle is too long.
Furthermore, the inner cavity parts of the cast strip head shell 3 are welded into a whole after being processed and ground by a numerical control machine tool, so that the processing is easy to realize, and the processing cost is low.
While the basic principles, principal features and advantages of the present invention have been shown and described, it will be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, which are described in the foregoing description merely illustrate the principles of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents.
