Description

Technical Field

[0001] The invention relates to the field of adhesive production, in particular to a dissolving and mixing device for adhesive production. Background Art

[0002] Adhesives can form a strong connection between two or more objects through their special chemical or physical properties. The principles mainly include physical adsorption and chemical reaction. Physical adsorption is the interaction force between the adhesive molecules and the molecules on the surface of the adherend, such as van der Waals force, which makes the two tightly bonded. The chemical reaction is that the chemical components in the adhesive react with the molecules on the surface of the adherend to form strong chemical bonds such as covalent bonds and ionic bonds, thereby achieving a strong bond. In the production process of adhesives, it is usually necessary to mix a variety of raw materials, some of which are in liquid state and some are in solid powder state. When dissolving each raw material in a water solvent, a dissolving and mixing device is required.

[0003] In the existing dissolving and mixing device for adhesive production, solid powder and liquid raw materials are usually put into the mixing tank from the top, and stirred by a stirring device in the mixing tank so that the solid powder and liquid raw materials are fully dissolved and mixed in the water solvent. For example, the invention patent with application number 202110675961.2 discloses a reactor for producing water-based adhesives. The invention radially rotates and stirs the adhesive in the inner cylinder through the main shaft connected to the bottom of the motor, and drives one of the four transmission shafts to rotate through the synchronous belt. The transmission shaft drives the reciprocating screw and the planetary gear to rotate, and then this set of planetary gears drives the main gear to rotate, and the main gear drives the other three sets of planetary gears to rotate. It can be seen that all four sets of reciprocating screws rotate, and when the four sets of reciprocating screws rotate, they drive the lifting mechanism to slide back and forth up and down. When sliding up and down, the matching gear meshing rack inside it rotates, and the reels on both sides of the matching gear drive two sets of rigid ropes and the lifting blocks and disturbance plates connected at their ends at the bottom of the inner cylinder to rise, so that the disturbance plate performs axial lifting and lowering motion inside the inner cylinder. It can be seen that not only the stirring rod rotates radially inside the inner cylinder, but also the disturbance plate performs axial reciprocating lifting and lowering motion inside the inner cylinder, thereby diversifying the trajectory of adhesive stirring and mixing, making the adhesive stirring and mixing reaction more uniform.

[0004] However, when the reactor of the above invention is used, solid materials are added to the inner cylinder through the feed pipe that penetrates the top cover and the top plate and extends to the inner cylinder. Due to the dampness of the solid materials, the solid powders are easy to aggregate and form powder lumps, which are not easy to be broken up by the stirring rod after entering the reactor. In addition, after the solid materials enter the inner cylinder, the materials float on the surface of the liquid, and a large number of agglomerates, aggregates and lumps are likely to appear. The agglomerates, aggregates and lumps cannot be broken up by the stirring rod alone, so that the solid materials and other raw materials are fully dissolved and mixed, thereby affecting the production efficiency and quality of the adhesive.

[0005] Therefore, it is necessary to develop a dissolving and mixing device for adhesive production in view of the above-mentioned defects. Summary of the invention

[0006] The purpose of the present invention is to provide a dissolving and mixing device for adhesive production, which can crush and disperse the solid powder material entering the mixing tank in advance, and at the same time can make the solid powder material be evenly dispersed into the liquid to avoid the formation of agglomerates and lumps, thereby improving the mixing efficiency and quality of the solid material and the liquid raw material.

[0037] Specifically, a bracket (not shown in the figure) is fixedly connected to the inner bottom surface of the mixing tank 1, and the bottom end of the rotating shaft 4 is rotatably connected to the bracket through a bearing, and the bearing is specifically a waterproof bearing.

[0038] In a specific embodiment of the present invention, Figures 6 to 9 As shown, the driving member includes a driving gear 1104, four driven gears 1105 and four connecting plates 1106, one end of the four connecting plates 1106 is fixedly connected to the inner wall of the premixing tube 9, and the other end of the four connecting plates 1106 is fixedly connected to a connecting ring 1107, and the rotating shaft 4 passes through the connecting ring 1107 and is rotatably connected thereto; the top ends of the four stirring rods 1101 are respectively and rotatably connected to the bottom surfaces of the connecting plates 1106 in a one-to-one correspondence, the driven gear 1105 is fixedly sleeved on the outer wall of the stirring rod 1101, the driving gear 1104 is fixedly sleeved on the outer wall of the rotating shaft 4, and the driving gear 1104 is respectively meshed with the four driven gears 1105.

[0039] The rotation of the rotating shaft 4 can drive the driving gear 1104 to rotate, and then drive the four driven gears 1105 meshing therewith to rotate, so as to achieve synchronous driving of the stirring rods 1101 to rotate.

[0040] Specifically, the width of the connecting plate 1106 is greater than the outer diameter of the driven gear 1105 , and the outer diameter of the connecting ring 1107 is greater than the outer diameter of the driving gear 1104 .

The scraper 1108 can scrape the material accumulated on the connecting plate 1106 and the connecting ring 1107, so that it falls from the gap between the connecting plates 1106 to the bottom of the premixing barrel 9.

[0043] In a specific embodiment of the present invention, Figures 2 to 5As shown, the crushing assembly 7 includes a crushing roller 701, a brush plate 702 and a screen plate 703. There are two crushing rollers 701 and two brush plates 702. A plurality of crushing needles 704 are fixedly connected to the outer walls of the two crushing rollers 701. The two crushing rollers 701 are symmetrically arranged and one end is rotatably connected to the outer walls of the rotating shaft 4 on both sides; a plurality of bristles 705 are fixedly connected to the bottom surfaces of the two brush plates 702. The two brush plates 702 are symmetrically arranged and one end is fixedly connected to the outer walls of the rotating shaft 4 on both sides; a plurality of sieve holes 706 are opened on the screen plate 703, and the screen plate 703 is arranged in the crushing box 6, and the bottom ends of the crushing needles 704 and the bristles 705 are both arranged in contact with the top surface of the screen plate 703.

[0044] The rotation of the rotating shaft 4 drives the crushing roller 701 and the brush plate 702 to rotate, and the crushing needles 704 on the crushing roller 701 can crush the solid powder materials that have fallen on the screen plate 703 and agglomerated, and the bristles 705 on the brush plate 702 can scrape the solid powder materials on the screen plate 703, and the screen holes 706 on the screen plate 703 allow smaller particles of solid powder materials to pass through the screen holes 706 and fall into the guide hopper 8 below.

[0045] Specifically, a scraper bar 713 made of elastic material is fixedly connected to the side surface of one end of the two brush plates 702 close to the crushing box 6 , and the scraper bar 713 is in contact with the inner wall of the crushing box 6 .

[0046] The scraper strip 713 can remove the materials stuck on the inner wall of the crushing box 6 .

[0047] Specifically, a plurality of connection seats 707 are fixedly connected to the inner wall of the bottom end of the crushing box 6, and an elastic member is fixedly connected to the top surface of each connection seat 707.

[0049] Through the cooperation between the crushing roller 701 and the protrusion 712, when the crushing roller 701 rotates to the protrusion 712, downward pressure is generated to squeeze the screen plate 703, so that the screen plate 703 slides downward along the inner wall of the crushing box 6, and at the same time drives the connecting rod 711 and the pressing plate 710 to slide downward in the inner wall of the slide 708 and squeeze the compression spring 709. After the crushing roller 701 passes the protrusion 712, the screen plate 703 is driven to move upward under the action of the restoring force of the compression spring 709. The up and down movement of the screen plate 703 can break the adhesion between the materials, so that the materials can pass through the screen hole 706 more easily.

Both ends of each group of first stirring paddles 1201 are fixedly connected with vertically arranged connecting columns 1202. A plurality of horizontally arranged second stirring paddles 1203 are fixedly connected with the side walls of the connecting columns 1202 at intervals along their length direction. The second stirring paddles 1203 are arranged toward the premixing barrel 9 and are spaced apart from the outer wall of the premixing barrel 9.

[0053] Working principle of the present invention: When the present invention is used, liquid material and water solvent are injected into the mixing tank 1 through the liquid inlet 13, the motor 3 is turned on, the rotating shaft 4 is driven to rotate, and then solid material is added into the mixing tank 1 through the feed port 5. After the solid material enters the mixing tank 1, it first falls onto the sieve plate 703 in the crushing box 6, and the rotating shaft 4 rotates to drive the crushing roller 701 and the brush plate 702 to rotate. The crushing needle 704 on the crushing roller 701 can crush the solid powder material that has agglomerated on the sieve plate 703, and the bristles 705 on the brush plate 702 can scrape the solid powder material on the sieve plate 703, and the sieve holes 706 on the sieve plate 703 allow smaller particles of solid powder material to pass through the sieve holes 706 and fall into the guide hopper 8 below it.

After premixing, the concentration in the premixing barrel 9 is high, and a concentration gradient is formed between the low-concentration solution outside the premixing barrel 9. The diffusion hole 10 provides a flow channel for the inside and outside of the premixing barrel 9. Under the combined action of the concentration gradient and molecular thermal motion, the high-concentration solid material solution will continuously migrate to the outside of the premixing barrel 9 through the diffusion hole 10 until the inside and outside of the premixing barrel 9 reach the same concentration. The solution in the premixing barrel 9 is stirred by the first stirring component 11 in the premixing barrel 9, the second stirring rod 1103 is driven to rotate by the rotation of the rotating shaft 4, and the first stirring rod 1102 is driven to rotate by the rotation of the four stirring rods 1101, which can enhance the stirring effect of the solution in the premixing barrel 9. At the same time, the first stirring rod 1102 on the stirring rod 1101 and the second stirring rod 1103 on the rotating shaft 4, which are staggered in the upper and lower intervals, can generate mutually superimposed stirring forces during the stirring process, which can further enhance the stirring intensity, so that the solid powder material is subjected to stronger shear and collision during the stirring process, avoiding the formation of agglomerates and lumps, so that the solid powder material can be evenly dispersed in the liquid, thereby improving the dissolution and mixing efficiency and quality of the solid material and the liquid raw material.
