Description

Technical Field

[0001] The utility model relates to the technical field of dipentaerythritol production, in particular to a dipentaerythritol production and purification device. Background Art

[0002] Dipentaerythritol (DPE) is a white powdery crystal, which is widely used in polymer industry, coating industry, printing and textile industry, and aerospace industry. Dipentaerythritol and most of its derivatives are biodegradable, non-toxic, environmentally friendly, and safe for human body. They are green chemicals and have become one of the most eye-catching new application raw materials in recent years. Dipentaerythritol is often used in the production of polyether, polyester, polyurethane, alkyd resin, and photosensitive resin film.

[0042] Furthermore, a plurality of connecting rods 6 are fixedly connected to the outer surface of the main rotating shaft 4;

[0043] The fixing ring 7 is arranged on a plurality of connecting rods 6, and one end of the connecting rod 6 away from the main rotating shaft 4 is fixedly connected to the inner wall of the fixing ring 7;

[0044] The gear ring 8 is fixedly sleeved on the inner wall of the fixing ring 7 .

[0045] Furthermore, a plurality of gears 9 are fixedly connected to the upper ends of the plurality of secondary rotating shafts 5;

[0046] Among them, a plurality of gears 9 are meshedly connected with the gear ring 8;

[0047] Wherein, a plurality of mixing rods 16 are fixedly connected to the outer surfaces of the main rotating shaft 4 and the secondary rotating shaft 5;

[0048] The mixing rod 16 is located inside the tank body 1 .

[0049] Furthermore, the sliding block 10 is fixedly connected to the outer surface of the main rotating shaft 4;

[0050] The outlet pipe 2 is fixedly connected to the outer surface of the tank body 1, and the outlet pipe 2 is communicated with the inside of the tank body 1;

[0051] The sliding groove 11 is formed on the upper surface of the sliding block 10 , and the sliding groove 11 extends downward from the lower surface of the sliding block 10 .

[0052] Furthermore, the motor 15 is fixedly connected to the upper surface of the tank body 1;

[0053] Wherein, the fixing rod 14 is fixedly connected to the rotating output shaft of the motor 15;

[0054] The fixing plate 13 is fixedly connected to the upper end of the fixing rod 14 .

[0055] Further, the fixing block 12 is fixedly connected to the upper surface of the fixing plate 13;

[0056] The fixing block 12 is slidably connected to the sliding groove 11 .

[0057] Furthermore, when in use, the motor 15 is started, and the motor 15 starts to drive the fixed rod 14 to rotate, and the rotation of the fixed rod 14 drives the fixed plate 13 and the fixed block 12 to rotate, and the fixed block 12 slides in the sliding groove 11 during the rotation process, and then synchronously drives the sliding block 10 to reciprocate around the main rotating shaft 4 as the center, and this rotation trajectory is fan-shaped, and the rotation of the main rotating shaft 4 synchronously drives the fixed ring 7 to rotate, and then, under the cooperation of the gear 9 and the gear ring 8, synchronously drives multiple secondary rotating shafts 5 to rotate;

[0058] As described above, when the motor 15 is started, the motor 15 starts to drive the main rotating shaft 4 and the secondary rotating shaft 5 to rotate, and then synchronously drives the mixing rod 16 to rotate, so as to stir and mix the raw materials for the production and purification of dipentaerythritol in the tank body 1, so that the purification effect of dipentaerythritol is better, the quality of dipentaerythritol is better, and the practicality of the dipentaerythritol production and purification device is increased;

[0059] As mentioned above, with the cooperation of the gear 9 and the gear ring 8, the main rotating shaft 4 synchronously drives the secondary rotating shaft 5 to rotate during the reciprocating rotation. Because the number of teeth of the gear 9 is small, when the main rotating shaft 4 reciprocates in a fan-shaped rotation, the secondary rotating shaft 5 is synchronously driven to perform reciprocating circular rotation, so that the mixing rods 16 on the main rotating shaft 4 and the secondary rotating shaft 5 have different rotation angles, so that the mixing rod 16 has a better effect and higher efficiency on mixing the raw materials for the production and purification of dipentaerythritol, thereby improving the efficiency of dipentaerythritol production, thereby ensuring that the purification device is more practical.

[0060] Working principle: When the device is used, the motor 15 is started, and the motor 15 starts to drive the fixed rod 14 to rotate. The rotation of the fixed rod 14 drives the fixed plate 13 and the fixed block 12 to rotate. The fixed block 12 slides in the sliding groove 11 during the rotation process, and then synchronously drives the sliding block 10 to reciprocate around the main rotating shaft 4 as the center. This rotation trajectory is fan-shaped. The rotation of the main rotating shaft 4 synchronously drives the fixed ring 7 to rotate, and then, with the cooperation of the gear 9 and the gear ring 8, it synchronously drives multiple secondary rotating shafts 5 to rotate;

[0061] As described above, when the motor 15 is started, the motor 15 starts to drive the main rotating shaft 4 and the secondary rotating shaft 5 to rotate, and then synchronously drives the mixing rod 16 to rotate, so as to stir and mix the raw materials for the production and purification of dipentaerythritol in the tank body 1, so that the purification effect of dipentaerythritol is better, the quality of dipentaerythritol is better, and the practicality of the dipentaerythritol production and purification device is increased;

[0062] As mentioned above, with the cooperation of the gear 9 and the gear ring 8, the main rotating shaft 4 synchronously drives the secondary rotating shaft 5 to rotate during the reciprocating rotation. Because the number of teeth of the gear 9 is small, when the main rotating shaft 4 reciprocates in a fan-shaped rotation, the secondary rotating shaft 5 is synchronously driven to perform reciprocating circular rotation, so that the mixing rods 16 on the main rotating shaft 4 and the secondary rotating shaft 5 have different rotation angles, so that the mixing rod 16 has a better effect and higher efficiency on mixing the raw materials for the production and purification of dipentaerythritol, thereby improving the efficiency of dipentaerythritol production, thereby ensuring that the purification device is more practical.
