Description

Technical Field

[0001] The present invention relates to the field of glycerol processing, and specifically to an auxiliary material feeding device for glycerol production. Background Art

[0002] With the development of industrial technology, modern glycerol processing has become increasingly perfect. Glycerol, also known as glycerin, has a wide range of uses. Glycerol can be used to manufacture antifreeze agents, lubricants, and food additives. The production of glycerol requires the mixing and heating of vegetable oil and alkaline solution for esterification reaction. However, the solution after the esterification reaction contains a lot of pigments, so it is necessary to put adsorption blocks into the solution to remove melanin.

[0003] For example, an auxiliary material feeding device for the production of triacetin proposed in Patent No. 202220915004.2 includes a driving motor, a rotating head, a cross frame, an annular guide rail, a hanging frame, a vibration motor, a first shock absorber, a second shock absorber, a solid material box, a liquid material box, and a liquid distributor. The utility model adopts a rotating feeding structure design and realizes the feeding of solid and liquid auxiliary materials, having the advantage of uniform feeding, which is conducive to the uniform dispersion of auxiliary materials, convenient for controlling the feeding amount of auxiliary materials according to the reaction process, reducing the waste of auxiliary materials, and reducing production costs.

[0004] When the invention is in use, it still has the following defects. After the device feeds the auxiliary materials, it is very difficult to fish out the unconsumed solid auxiliary materials and solid catalysts, which will result in a lot of residues of unconsumed solid auxiliary materials and solid catalysts in the product.

[0026] Please refer to Figures 1-5 , an auxiliary material feeding device for glycerol production, including a reaction tank 1. Vegetable oil and sodium hydroxide solution are filled inside the reaction tank 1. A sandwich layer is provided in the side wall of the reaction tank 1, and an electric heating wire is provided in the sandwich layer. The electric heating wire heats the solution to fifty degrees Celsius; rectangular slots are provided on the left and right sides of the reaction tank 1, and positioning rods 2 are provided in the rectangular slots. An adjusting plate 3 is provided at the top of the positioning rod 2. The positioning rod 2 is connected to a height adjusting mechanism; a stepping motor 5 is provided at the top of the adjusting plate 3. A telescopic shaft mechanism is provided at the output end of the stepping motor 5. The telescopic shaft mechanism is connected to a lifting mechanism. An activated carbon stirring disc is provided on the telescopic shaft mechanism, and activated carbon balls are hung on the activated carbon stirring disc. The activated carbon balls are placed on the activated carbon stirring disc, and the activated carbon stirring disc carries the activated carbon balls and sinks into the solution for stirring. The activated carbon balls can efficiently adsorb pigments in the solution during the stirring process. Compared with the adsorption method of powdered activated carbon, the powdered activated carbon still needs to be separated later. The activated carbon balls of the present invention can be directly fished out, which saves operation time.

[0027] The height adjusting mechanism includes positioning holes arranged in a linear array on the positioning rod 2. Locking holes are provided in the rectangular slots on the side wall of the reaction tank 1. The locking holes and the positioning holes are connected by pin rods. According to the processing requirements, the staff pulls out the pin rods on the positioning rod 2, and then inserts the pin rods back after the positioning rod 2 is adjusted to the appropriate height.

[0028] The activated carbon stirring disk includes a stirring disk 7. There are three arc-shaped blades 701 arranged on the outer side wall of the stirring disk 7. The inside of the arc-shaped blade 701 is hollow. Activated carbon balls are loaded into the inside of the arc-shaped blade 701. An opening is provided at the end of the arc-shaped blade 701. A receiving port 702 is provided on the inner arc side wall of the arc-shaped blade 701. A water filtering port 703 is provided on the outer arc side wall of the arc-shaped blade 701. A one-way valve flap is provided inside the receiving port 702, and the water flow direction of the one-way valve flap is from the outside of the arc-shaped blade 701 to the inside of the arc-shaped blade 701. A wire mesh is provided inside the water filtering port 703. When the stirring disk 7 rotates forward, the activated carbon balls inside the arc-shaped blade 701 are thrown out from the port of the arc-shaped blade 701 under the action of centripetal force, and the arc-shaped blade 701 will stir the activated carbon balls to move in the solution and adsorb pigments. When the stirring disk 7 rotates in the reverse direction, the activated carbon balls will penetrate into the arc-shaped blade 701 through the receiving port 702 for re-collection. The water filtering port 703 and the wire mesh inside it can balance the solution pressure inside the arc-shaped blade 701, and the receiving port 702 and the one-way valve flap inside it can prevent the activated carbon balls from running out again.

[0029] The outer side of the arc-shaped blade 701 is made of soft rubber, and an elastic steel sheet is inserted into the side wall of the arc-shaped blade 701. When the stirring disk 7 rotates towards the outer arc surface direction of the arc-shaped blade 701, the outer arc surface of the arc-shaped blade 701 will bend inward under the liquid pressure. When the stirring disk 7 rotates in the reverse direction, the arc-shaped blade 701 will expand away from the stirring disk 7, facilitating the collection of the activated carbon balls at the bottom of the solution.

[0030] The activated carbon stirring disk includes a torsion disk 8. Three arc-shaped tiles 801 are provided on the outer side wall of the torsion disk 8.

The inside of the arc-shaped tile 801 is hollow, and the hollow interlayer inside the arc-shaped tile 801 is connected to the space inside the straight cylinder 802. Three pressure holes 805 are provided on the inner arc surface of the arc-shaped tile 801. Three shoveling tiles 806 are provided on the outer side wall of the torsion disk 8. The three shoveling tiles 806 are respectively attached to the root of the side wall of the inner arc surface of the arc-shaped tile 801. The arc-shaped tile 801 is made of aluminum alloy. The activated carbon balls to be processed are placed on the shoveling tiles 806 and sink into the solution. When the torsion disk 8 rotates towards the outer arc surface direction of the arc-shaped tile 801, after the bevel block 804 is subjected to the liquid pressure, the bevel block 804 and the telescopic piece 803 will contract into the straight cylinder 802 and stir the solution and the activated carbon balls. When the torsion disk 8 flips, the solution will apply liquid pressure to the inside of the arc-shaped tile 801 from the pressure holes 805, and the telescopic piece 803 will be pushed out by the liquid pressure. Furthermore, the telescopic piece 803 will be attached to the inner side wall of the reaction tank 1, and the activated carbon balls will finally be collected and fished up by the shoveling tiles 806.

[0031] The telescopic shaft mechanism includes a central tube 6. A rectangular channel is provided inside the central tube 6. A square shaft 501 is slidably inserted into the rectangular channel. The square shaft 501 is connected to the output shaft of the stepping motor 5. A buffer shaft assembly is provided at the bottom end of the central tube 6. The stepping motor 5 drives the square shaft 501 and the central tube 6 to rotate. During the lifting process of the central tube 6 and the activated carbon stirring disk at its bottom end, the square shaft 501 and the central tube 6 can be inserted and change in length, and the stepping motor 5 can always drive the activated carbon stirring disk to rotate.

[0032] The buffer shaft assembly includes a docking rod 604 below the central tube 6. A rubber block 602 is provided between the central tube 6 and the docking rod 604. Insertion pieces are provided at both the upper and lower ends of the rubber block 602. Slots matching the insertion pieces are provided on the central tube 6 and the docking rod 604. Pin holes 603 are provided on the central tube 6, the docking rod 604, and the insertion pieces. The upper and lower pin holes 603 are fixedly connected by inserting rods. The docking rod 604 is respectively connected to the axis of the stirring disk 7 or the torsion disk 8. The rubber block 602 can buffer the stirring power of the stirring disk 7 or the torsion disk 8, and the stepping motor 5 will not generate a rigid shock to the stirring disk 7 or the torsion disk 8 at the moment of starting or stopping.

[0033] The lifting mechanism includes a bearing 601 at the top end of the central tube 6. The inner ring of the bearing 601 is fixedly connected to the outer side wall of the central tube 6. A lifting plate 402 is fixedly installed on the outer ring of the bearing 601. The top end of the adjusting plate 3 is further provided with an electric push rod 4. The output end of the electric push rod 4 is equipped with a lifting rod 401. The end of the lifting rod 401 is connected to the top surface of the lifting plate 402. The electric push rod 4 drives the central tube 6 to lift and lower through the lifting plate 402 until the mixing disk 7 or the torsion disk 8 is disengaged from the opening of the reaction tank, and then the staff can replace the activated carbon balls.

[0034] Working principle: The activated carbon stirring disk carries activated carbon balls and sinks into the interior of the solution for stirring. During the stirring process, the activated carbon balls can efficiently adsorb the pigments in the solution. Compared with the adsorption method of powdered activated carbon, the powdered activated carbon still needs to be separated later. The activated carbon balls of the present invention can be directly fished out, which saves operation time. According to the processing requirements, the staff pulls out the pin on the positioning rod 2, and then inserts the pin back after the positioning rod 2 is adjusted to the appropriate height. When the stirring disk 7 rotates forward, the activated carbon balls inside the arc-shaped blade 701 are thrown out from the port of the arc-shaped blade 701 under the action of centripetal force, and the arc-shaped blade 701 will stir the activated carbon balls to move in the solution and adsorb pigments. When the stirring disk 7 rotates in the reverse direction, the activated carbon balls will penetrate into the arc-shaped blade 701 through the storage port 702 for re-collection and fishing. The water filter port 703 and the wire mesh inside it can balance the solution pressure inside the arc-shaped blade 701, and the storage port 702 and the one-way valve inside it can prevent the activated carbon balls from running out again. When the stirring disk 7 rotates towards the outer arc surface direction of the arc-shaped blade 701, the outer arc surface of the arc-shaped blade 701 will bend inward under the liquid pressure. When the stirring disk 7 rotates in the reverse direction, the arc-shaped blade 701 will expand away from the stirring disk 7, facilitating the collection of the activated carbon balls at the bottom of the solution. The activated carbon balls to be processed are placed on the shoveling tile 806 and sink into the solution. When the torsion disk 8 rotates towards the outer arc surface direction of the arc-shaped tile 801, after the inclined plane block 804 is subjected to the liquid pressure, the inclined plane block 804 and the telescopic piece 803 will contract into the interior of the straight cylinder 802 and stir the solution and the activated carbon balls. When the torsion disk 8 flips, the solution will apply liquid pressure to the interior of the arc-shaped tile 801 through the pressure hole 805, and the telescopic piece 803 will be pushed out by the liquid pressure. Then, the telescopic piece 803 will fit against the inner wall of the reaction tank 1, and the activated carbon balls will finally be collected on the shoveling tile 806 and fished out. The stepping motor 5 drives the square shaft 501 and the central tube 6 to rotate. During the lifting and lowering process of the central tube 6 and the activated carbon stirring disk at its bottom end, the square shaft 501 and the central tube 6 can be inserted and changed in length. The stepping motor 5 can always drive the activated carbon stirring disk to rotate. The rubber block 602 can buffer the stirring power of the stirring disk 7 or the torsion disk 8, and the stepping motor 5 will not generate a rigid shock to the stirring disk 7 or the torsion disk 8 at the moment of starting or stopping. The electric push rod 4 drives the central tube 6 to lift and lower through the lifting plate 402 until the stirring disk 7 or the torsion disk 8 is removed from the opening of the reaction tank, and the staff replaces the activated carbon balls.
