Description

Technical Field

[0001] This utility model relates to the field of sebacic acid technology, and in particular to a sebacic acid granulation device. Background Technology

[0002] Sebacic acid, chemically known as diethyl sebacic acid, is an aliphatic dicarboxylic acid with the chemical formula C10H18O4. It is also called sebacic acid, octyl-1,8-dicarboxylic acid, etc. Sebacic acid is a white, flaky crystal at room temperature, slightly soluble in water, sparingly soluble in benzene, petroleum ether, and carbon tetrachloride, but readily soluble in ethanol and diethyl ether. Sebacic acid has a wide range of applications, primarily used to produce esters of sebacic acid.

The device also includes a screen, a packaging hopper, a powder collection box, and a return air pipe. A connecting rod is welded to the bottom of the conical collecting hopper; vibration holes are formed in the screen, with the end of the connecting rod passing through the vibration holes; the powder collection box is fixed below the screen; the packaging hopper is fixed to the discharge end of the screen; and the return air pipe is connected to the air inlet pipe via a pipe equipped with an exhaust fan. This invention produces uniform granulation, generates no dust, has no material loss, has a simple structure, and is easy to clean.

[0004] However, in the existing technology mentioned above, the process of granulating sebacic acid usually involves using a fan and a powder return pipe to send the ungranulated sebacic acid powder back into the tower. During the process of the sebacic acid powder flowing back into the tower, the powder will come into direct contact with the fan, which can easily damage the fan and thus affect the reflux effect of the equipment.

[0016] 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.

[0017] Reference Figure 1-5 This utility model provides a sebacic acid granulation device, including a tower body 1, a collection hopper 2 fixedly connected to the middle of the inner wall of the tower body 1, a vibrating screen 3 provided on the inner wall of the tower body 1 away from the bottom of the collection hopper 2, a packaging hopper 4 fixedly connected to one side of the vibrating screen 3, baffles 5 provided on the top of both the vibrating screen 3 and the packaging hopper 4, a collection box 6 provided on the inner wall of the tower body 1 away from the bottom of the vibrating screen 3, an adsorption tube 7 penetrating the tower body 1 provided at the bottom of the collection box 6, an anti-backflow mechanism connected to the top of the adsorption tube 7 provided on the outer contour of the tower body 1 near the middle, and a weight detection mechanism provided inside the collection box 6.

[0018] Sebacic acid powder to be granulated is fed into tower 1 through nozzles installed at the top of the inner wall of tower 1. Then, granulated sebacic acid granules and ungranulated sebacic acid powder are discharged onto vibrating screen 3 through collecting hopper 2. The powder is then filtered through vibrating screen 3 into collecting box 6, and then discharged and packaged through packaging hopper 4. The ungranulated powder collected in collecting box 6 is collected by a weight detection mechanism. When the weight in collecting box 6 reaches the preset value of the operator, the anti-backflow mechanism is activated, and the ungranulated sebacic acid powder collected in collecting box 6 is fed back into tower 1 for granulation. This effectively solves the problem that sebacic acid powder easily comes into contact with adsorption fan 14 during operation of existing equipment, which can easily damage adsorption fan 14, thus improving the practicality of the equipment.

[0019] The anti-backflow mechanism includes an equipment box 8 fixedly connected to the outer contour of the tower body 1 near the middle. A filter screen 11 is inclinedly arranged on the inner wall of the equipment box 8. An adsorption chamber 12 is formed on one side of the inner cavity of the equipment box 8 through the filter screen 11, and a backflow chamber 13 is formed on the other side of the inner cavity of the equipment box 8 through the filter screen 11. An adsorption fan 14 is fixedly connected to one side of the inner wall of the adsorption chamber 12. A discharge trough 15 is opened at the bottom of the backflow chamber 13. A backflow hopper 16 is fixedly connected to the bottom of the equipment box 8. A backflow pipe 9 penetrating the tower body 1 is fixedly connected to the bottom of the backflow hopper 16. The weight checking mechanism includes a receiving box 10 snapped into the inner wall of the collecting box 6. Weight sensors 101 are arrayed at the bottom of the inner wall of the collecting box 6. The bottom of the receiving box 10 is in contact with the top of the weight sensors 101.

[0020] When sebacic acid powder falls into the receiving box 10 that is snapped into the collecting box 6, the weight sensor 101 simultaneously detects the powder collected in the receiving box 101. When the weight sensor 101 detects that the weight in the receiving box 10 reaches the preset value set by the operator, the weight sensor 101 sends an electrical signal to the controller, causing the controller to start the adsorption fan 14. The suction force generated by the adsorption fan 14 in the adsorption chamber 12 sends the powder collected in the receiving box 10 through the adsorption tube 7 to the return chamber 13 formed in the equipment box 8. The powder is then filtered by the filter screen 11 as it enters the equipment box 8, preventing the powder from contacting the adsorption fan 14 and thus avoiding damage to the adsorption fan 14. This further improves the effectiveness of the equipment.

[0021] Both ends of the filter screen 11 are fixedly connected to mounting rods 17. The inner wall of the equipment box 8 is provided with a mounting groove 18 for the mounting rods 17 to be engaged. The top of the mounting rod 17 is provided with a fastening bolt 19 and is bolted to the inner wall of the mounting groove 18. The main view shape of the two mounting rods 17 is T-shaped, and the main view shape of the two mounting grooves 18 is the same as that of the two mounting rods 17.

[0022] During prolonged use of the equipment, when the filter screen 11 is damaged, the operator removes the fastening bolt 19 from the mounting rod 17, then pulls the filter screen 11 to move the mounting rod 17 out of the mounting groove 18. A new filter screen 11 is then removed, and the mounting rod 17 is inserted into the mounting groove 18. The fastening bolt 19 is then installed on the mounting rod 17 and the mounting groove 18, thus completing the replacement of the filter screen 11. Furthermore, the T-shaped mounting rod 17 and mounting groove 18 facilitate the positioning of the filter screen 11 during installation and provide a good limiting effect during use.

[0023] Working principle: First, the sebacic acid powder to be granulated is fed into the tower 1 through a nozzle set at the top of the inner wall of the tower 1. Then, the granulated sebacic acid granules and ungranulated sebacic acid powder are discharged onto the vibrating screen 3 through the collecting hopper 2. The powder is then filtered through the vibrating screen 3 into the collecting box 6. The sebacic acid granules are then discharged and packaged through the packaging hopper 4. When the sebacic acid powder falls into the receiving box 10 that is engaged in the collecting box 6, the weight sensor 101 simultaneously monitors the contents of the weight sensor 101. The collected powder is tested. When the weight sensor 101 detects that the weight in the collection box 10 reaches the preset value of the operator, the weight sensor 101 sends an electrical signal to the controller, which causes the controller to start the adsorption fan 14. The suction force generated by the adsorption fan 14 in the adsorption chamber 12 sends the powder collected in the collection box 10 through the adsorption tube 7 to the return chamber 13 formed in the equipment box 8. The powder is filtered by the filter screen 11 when it enters the equipment box 8 to prevent the powder from contacting the adsorption fan 14.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
