Description

Technical Field

[0001] This utility model relates to the field of raw material tanks, specifically a raw material tank with heat preservation function. Background Technology

[0002] Raw material tanks are used to store, protect, and manage the raw materials required for production. They are widely used in the chemical, food, and brewing industries. In polyester production, 1,4-butanediol is an important organic liquid raw material. This raw material may crystallize when the temperature is too low in winter. Once crystallized, it will affect its subsequent use. Therefore, it is necessary to keep it warm and heat it.

[0003] The publication number CN213333652U discloses a 1,4-butanediol storage tank, which includes a tank body, a first, a second, and a connecting pipeline. The lower part of the inner cavity of the tank body is provided with a steam coil, and the first end of the first pipeline is connected to the bottom of the tank body.

[0004] The aforementioned storage tank can temporarily store large quantities of 1,4-butanediol as a raw material. However, during the slow heating process, the heating of the raw material at the top is relatively slow due to the height of the tank. In particular, once crystallization occurs, it may take a whole day to reheat the 1,4-butanediol. Moreover, the 1,4-butanediol crystals near the inner wall of the tank will adhere to the inner wall of the tank and dissolve relatively slowly when the tank is stationary inside.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1.

[0024] Combination Figures 1-4 A raw material tank with heat preservation function includes a tank body 1, a heating plate 2 installed at the bottom of the tank body 1, a heat equalization mechanism 3 installed inside the tank body 1, and a scraping assembly 4 installed on the inner wall of the tank body 1.

[0025] See Figure 3 Furthermore, the heating mechanism 3 includes a conduit 5, which is movably installed inside the tank 1. A base plate 6 is installed at the bottom end of the conduit 5. Several guide grooves 7 are opened on the outside of the conduit 5. A first motor 8 is installed at the top of the tank 1. A rotating rod 9 is installed at the bottom end of the output shaft of the first motor 8. A spiral blade 10 is provided on the outside of the rotating rod 9. The lower ends of the rotating rod 9 and the spiral blade 10 are close to but not close to the base plate 6.

[0026] The first motor 8 is fixedly installed on the top of the tank 1, and the guide tube 5 is fixedly installed between the base plate 6. The first motor 8 is used to drive the rotating rod 9 to rotate, and the raw material flows upward through the spiral blade 10.

[0027] The inside of the conduit 5 is hollow, and the inside of the conduit 5 is interconnected through the guide groove 7. The raw material is conveyed upward by the spiral blade 10 and discharged through the guide groove 7.

[0028] The rotating rod 9 is located inside the guide tube 5 and rotates movably. The rotating rod 9 is fixedly connected to the output shaft of the first motor 8. The spiral blade 10 is used for the vertical conveying of raw materials to realize the vertical circulation of raw materials.

[0029] Specifically, when crystallization occurs, the heating plate 2 heats the crystallizing raw material at the bottom of the tank 1 to a certain degree and turns it into liquid raw material. The first motor 8 is started to rotate the rotating rod 9. When there is little crystallization, the first motor 8 is started directly to rotate the rotating rod 9. The liquid raw material enters the guide tube 5 through the guide groove 7 and is conveyed upward through the spiral blade 10. It is discharged sequentially through the guide groove 7 at the top, thereby causing the raw material at the top to move downward and be heated alternately.

[0030] Example 2.

[0031] See Figure 4Furthermore, based on Embodiment 1, the scraping assembly 4 includes two scrapers 12, which are fixedly installed on the outside of the chassis 6. A second motor 11 is installed at the bottom of the chassis 6, and the scrapers 12 are installed on the outer side of the chassis 6. The vertical part of the scraper 12 is provided with a rubber scraper 14 adapted to the inner wall of the tank. Several stirring rods 13 are fixedly installed on the outside of the guide tube 5. A limiting groove is opened in the center of the bottom surface of the tank 1. The lower end of the chassis 6 is movably placed in the limiting groove, and at least 3 / 4 of its height extends out of the limiting groove. The limiting groove provides support and limiting for the chassis 6. Under the action of the second motor 11, the chassis 6 rotates circumferentially in the limiting groove on the bottom surface of the tank 1. The scraper 12 is an L-shaped plate, whose horizontal part does not contact the bottom surface of the tank 1, and whose vertical part is provided with a rubber scraper 14 that contacts the inner wall of the tank.

[0032] The output shaft of the second motor 11 is fixedly connected to the chassis 6. The stirring rod 13 surrounds the outside of the guide tube 5. The second motor 11 drives the chassis 6 to rotate, thereby causing the guide tube 5 to rotate. The rotation direction of the guide tube 5 is opposite to the rotation direction of the spiral blade 10 arranged on the rotating shaft. Both can work normally when started at the same time, or one can work while the other remains stationary.

[0033] Two scrapers 12 are arranged symmetrically to each other. The rubber scraper 14 located on the outer side of the scraper 12 can slide along the inner wall of the tank body 1. The raw material crystals adhering to the inner wall of the tank body 1 are scraped off by the rubber scraper 14. In the preferred embodiment, an annular boss 15 is provided on the inner side of the top surface of the tank body 1. A limiting groove is formed between the annular boss 15 and the circumferential side wall of the tank body 1. The top ends of the scraper 12 and the rubber scraper 14 are movably disposed in the limiting groove and can rotate in the limiting groove.

[0034] Specifically, the second motor 11 drives the guide tube 5 to rotate, which in turn drives the scraper 12 to rotate. This causes the rubber scraper 14 on the outside of the scraper 12 to slide along the inner wall of the tank 1, which can scrape off the raw material crystals adhering to the inner wall of the tank 1, accelerate dissolution, and improve the utilization rate of the raw materials.

[0035] In actual operation, the raw materials are added through the feed port of tank 1. A pump pipe is connected to the bottom of the outside of tank 1. The raw materials are transported to the mixing tank and reaction vessel for use through the pipeline and the transfer pump. Since 1,4-butanediol will crystallize at low temperature, affecting subsequent use, the raw materials can be slowly heated in advance by the heating plate 2 at the bottom of tank 1.

[0036] When heating raw materials, if the raw materials inside the tank 1 crystallize in a low-temperature environment, the raw materials need to be heated first by the heating plate 2. When the crystallized raw materials at the bottom of the tank 1 are heated into liquid raw materials, the first motor 8 is started to realize the circulation of raw materials up and down. When a small amount of raw materials crystallize, the first motor 8 can be started at the same time during heating to realize the circulation of raw materials up and down.

[0037] Because the tank 1 is relatively high, the first motor 8 is started, which drives the rotating rod 9 to rotate. The liquid raw material enters the guide tube 5 through the guide groove 7 and is transported upward by the spiral blade 10. At the same time, the raw material at the top of the tank 1 moves downward, so that the raw material inside the tank 1 is alternately heated.

[0038] The second motor 11 is started to rotate the guide tube 5, which in turn drives the two scrapers 12 to rotate. The rubber scraper 14 on the outside of the scraper 12 scrapes off the raw material crystals adhering to the inner wall of the tank 1, thereby improving the utilization rate of the raw materials. At the same time, the guide tube 5 drives the stirring rod 13 to rotate, thereby improving the flowability of the raw materials. The scraper 12 mainly plays a role when the raw materials crystallize and adhere to the inner wall. When there is no crystallization, the stirring rod 13 is mainly used to rotate to improve the flowability of the raw materials.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
