Description

Technical Field

[0001] The utility model relates to the technical field of petroleum resins, and more specifically, it relates to a hydrogenated petroleum resin mixing and melting device. Background Technique

[0002] Petroleum resin gets its name because its source is petroleum derivatives. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, is chemically stable to acids and alkalis, and has the characteristics of good viscosity regulation and thermal stability. Petroleum resin is generally not used alone, but is used together with other resins as a promoter, regulator, modifier, etc.;

[0003] Hydrogenated petroleum resin, also known as hydrogenated petroleum resin, is white or light yellow, with a relative density of 1.01. It has a lighter color and improved aging resistance. In order to improve the compatibility of hydrogenated petroleum resin with other polymers, improve water solubility, optimize performance, and expand the application range, during use, according to the usage requirements, the petroleum resin is mixed and melted with other materials and additives, so as to meet the usage requirements. Therefore, a mixing and melting device is needed;

[0004] In the related technology, for a hydrogenated petroleum resin mixing and melting device, after the hydrogenated petroleum resin material is melted, the control valve is opened to discharge the melted hydrogenated petroleum resin material. The telescopic rod is controlled to extend, and the telescopic rod makes the push plate descend, which can effectively improve the discharging speed of the hydrogenated petroleum resin, and the push plate can scrape off the high hydrogenated petroleum resin on the inner part of the heating and melting tank;

[0005] The above-mentioned existing technical solutions have the following defects: when putting the hydrogenated petroleum resin, it is not only the petroleum resin that is put in, but also other materials and additives need to be added according to the usage requirements. When melting the petroleum resin, additives and other materials, it will cause uneven mixing, resulting in the melted petroleum resin not meeting the usage requirements. And when a push plate is arranged in the heating tank and the materials in the heating tank are discharged by the descending of the push plate, it cannot achieve a good cleaning effect on the inner wall of the heating tank.

[0037] Specifically, one side of the outer shell 1 is connected with a first support frame 9, the top of the first support frame 9 is connected with a second support frame 10, one side of the second support frame 10 is connected with a driving motor 11, the top end of the first rotating shaft 4 passes through the first support frame 9 movably and is connected to the output shaft of the driving motor 11, a first transmission gear 12 is connected to the first rotating shaft 4, the first transmission gear 12 is located above the heating tank 3, a second transmission gear 17 is rotatably connected to the second rotating shaft 16, the second transmission gear 17 is located above the material transfer cylinder 14, the first transmission gear 12 and the second transmission gear 17 are in the same plane, and the first transmission gear 12 and the second transmission gear 17 are connected and driven by a chain 18.

[0038] By adopting the above technical solution, through the driving motor 11, it is convenient to drive the stirring frame 5 and the spiral scraper 6 in the heating tank 3 to rotate. Through the first transmission gear 12, the second transmission gear 17, the chain 18 and the second rotating shaft 16, etc., while the first rotating shaft 4 drives the stirring frame 5 in the heating tank 3 to rotate and stir, the feeding operation is carried out on the heating tank 3 through the feeding cylinder 14, making the mixing effect of the materials better.

At this time, when the first rotating shaft 4 rotates, it synchronously drives the second transmission gear 17 to rotate on the second rotating shaft 16, and the auger 15 in the feeding cylinder 14 will not rotate.

[0041] Embodiment 2:

[0042] On the basis of Embodiment 1, please refer to Figure 2 and Figure 3 .

[0043] Specifically, a feed pipe 22 is connected to the bottom of one side of the feeding cylinder 14. The feed pipe 22 is communicated with the feeding cylinder 14. The other end of the feed pipe 22 is connected with a feed hopper 23. A first discharge pipe 24 is connected to the top of the other side of the feeding cylinder 14. The first discharge pipe 24 is communicated with the feeding cylinder 14. A second discharge pipe 25 is sleeved on the first discharge pipe 24. A feed inlet 7 is opened on the top of the heating tank 3, and the second discharge pipe 25 is matched with the feed inlet 7.

[0044] By adopting the above technical solution, through the feed pipe 22 and the feed hopper 23, it is convenient to sequentially add the materials to be melted. Through the first discharge pipe 24 and the second discharge pipe 25, it is convenient to be matched with the feed inlet 7 on the heating tank 3 to put the materials into the heating tank 3. After the feeding is completed, the second discharge pipe 25 is pushed, so as to conveniently seal the feed inlet 7 on the heating tank 3.

[0045] Specifically, a support base 2 is connected to the bottom of the outer shell 1, a discharge port 26 is provided at the bottom of the heating tank 3, the discharge port 26 is located below the outer shell 1, a heating device is provided between the outer shell 1 and the heating tank 3, and the heating device used by the heating device is not shown in the figure to heat the heating tank 3, thereby completing the operation of melting the material. An exhaust pipe 8 is provided at the top of the heating tank 3, and the exhaust pipe 8 is communicated with the heating tank 3.

[0046] By adopting the above technical solution, through the discharge port 26, it is convenient to discharge the melted material. Through the exhaust pipe 8, the waste gas generated by heating the material is discharged and put into the waste gas treatment mechanism for treatment operation (the waste gas treatment mechanism is not shown in the figure).

[0047] The working principle of the present utility model is as follows: When in use, the staff puts other materials such as petroleum resin and additives into the feed hopper 23 successively according to the use requirements, and the material falling into the feed hopper 23 slides through the feed pipe 22 and falls to the bottom of the feeding cylinder 14;

[0048] The staff pushes the stop rod 20 on the top plate 19 to make the stop rod 20 insert into the limit hole 21 on the second transmission gear 17 to limit the second transmission gear 17, so that the second transmission gear 17 and the second rotating shaft 16 become an integral body. Powered by an external power supply, the drive motor 11 starts to work, drives the first rotating shaft 4 to rotate, drives the first transmission gear 12 connected to the first rotating shaft 4 to rotate, and thus drives the second transmission gear 17 to rotate through the transmission of the chain 18, drives the second rotating shaft 16 to rotate on the top of the feeding cylinder 14, drives the auger 15 in the feeding cylinder 14 to rotate, and rotates and conveys the material accumulated at the bottom of the feeding cylinder 14;

[0049] When the material rises to the position of the first discharge pipe 24 of the feeding cylinder 14, the staff slides the second discharge pipe 25 on the first discharge pipe 24, so that the outlet position of the second discharge pipe 25 inserts into the feed port 7 of the heating tank 3. A channel is connected through the first discharge pipe 24 and the second discharge pipe 25 to make the material completely enter the heating tank 3. After the material in the feeding cylinder 14 is conveyed to the upper part of the feeding cylinder 14, it is discharged at the first discharge pipe 24 and enters the heating tank 3 through the second discharge pipe 25;

[0050] When the first rotating shaft 4 rotates, it synchronously drives the stirring frame 5 and the spiral scraper 6 located in the heating tank 3 to rotate, stir and mix the material put into the heating tank 3, and through the cooperation of the stirring frame 5 and the spiral scraper 6, the material is mixed more evenly;

[0051] After the feeding of the material is completed, the staff member moves the second discharge pipe 25 by pushing it, so that the second discharge pipe 25 moves away from the feed inlet 7 of the heating tank 3 and is sleeved on the first discharge pipe 24. Then, the position of the feed inlet 7 of the heating tank 3 is sealed. By pulling the stop lever 20 to raise it on the top plate 19, the stop lever 20 is removed from the limit hole 21, so that the second transmission gear 17 cannot limit the second rotating shaft 16. At this time, when the first rotating shaft 4 rotates, the first transmission gear 12 drives the second transmission gear 17 to rotate on the second rotating shaft 16 through the chain 18, and does not drive the second rotating shaft 16 to rotate. Therefore, the auger 15 in the feeding cylinder 14 stops working and the feeding operation is stopped;

[0052] The heating tank 3 is heated by the heating device provided between the outer shell 1 and the heating tank 3, and the put-in material is melted. At this time, the stirring frame 5 and the spiral scraper 6 in the heating tank 3 still keep rotating to assist in the melting operation. After the melting operation is completed, the driving motor 11 rotates in the reverse direction, and the spiral scraper 6 rotates in the reverse direction to scrape the residual material on the inner wall of the heating tank 3 downward for cleaning, so that the material smoothly falls below the heating tank 3. The staff member places a container for holding the material on the support base 2, and discharges the material through the discharge port 26. The exhaust gas generated by heating is discharged through the exhaust pipe 8 provided above the heating tank 3 and is sent into the exhaust gas treatment mechanism for treatment operation.

[0053] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
