Description

Technical Field

[0001] This utility model relates to the field of water-based drying agent production technology, specifically to a water-based drying agent preparation device. Background Technology

[0002] Waterborne driers are additives used to accelerate the drying process of waterborne coatings. They are widely used in the coatings industry, especially in air-drying resin systems such as waterborne alkyd and epoxy ester resins. In the process of making waterborne driers, solid metal salts (such as cobalt isooctanoate and zinc naphthenate) or emulsifiers need to be dissolved in deionized water to achieve the formulation of solid particles. In the prior art, patent CN217698983U discloses a solid material dissolving tank, including a tank body, a feed inlet, a liquid inlet, and a discharge outlet. The top of the tank body is equipped with a stirring motor, which is connected to a stirring shaft. There are partitions between the two inner walls on the upper side of the tank body, and a screen is connected between the partitions. The stirring shaft passes through the top of the tank body and the screen and extends to the lower part of the tank body. Several crushing rods are fixedly installed on the part of the stirring shaft above the screen, and a stirring paddle is fixedly installed at the bottom end of the stirring shaft. The above-mentioned dissolving tank has some problems in actual use. For example, when the crushed solid particles fall into the tank, the size of the particles depends on the mesh size of the screen. When the mesh size is large, some particles will still sink to the bottom. At this time, the stirring shaft stirs these solid raw materials, and the dissolved particles at the bottom are dissolved slowly. Therefore, we propose a water-based drying agent preparation device.

[0014] 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.

[0015] Please see Figure 1-3 This embodiment provides a technical solution: an aqueous drying agent preparation device, including a preparation tank 1 and a rapid mixing mechanism 4; Preparation tank 1: A top cover 2 is fixedly connected to its upper side. A rotating plate 3 is rotatably connected to the lower side of the inner arc surface of the top cover 2 via a slewing bearing. A controller 13 is installed outside the preparation tank 1. The input terminal of the controller 13 is electrically connected to an external power source. The edge of the top cover 2 has evenly distributed feed pipes 6, all six of which extend into the interior of the preparation tank 1. A feed channel 7 is located on the upper right side of the preparation tank 1. A soft-seal butterfly valve is connected in series in the middle of the feed channel 7. The soft-seal butterfly valve is a D371X rubber soft-seal butterfly valve. The butterfly valve can be opened during feeding and closed after feeding is complete. A discharge pipe 9 is located at the bottom of the preparation tank 1 (a solenoid valve can be connected in series at the discharge pipe 9). The solenoid valve is then controlled by controller 13. Once the dissolution process is complete, the solenoid valve can be opened to discharge the liquid. The right end of the discharge pipe 9 is connected to an external collection device, and the upper ends of the six feed pipes 6 are connected to an external raw liquid supply device. The lower surface of the preparation tank 1 is provided with evenly distributed support legs 8. The inner wall of the preparation tank 1 is provided with a heating pipe 10. The lower inlet and upper outlet of the heating pipe 10 are respectively connected to an external heating liquid circulation device. Temperature sensors 12 are evenly distributed on the outer surface of the preparation tank 1. The measuring ends of the temperature sensors 12 all extend into the interior of the preparation tank 1. The temperature sensors 12 are bidirectionally electrically connected to the controller 13 (here). The temperature sensors 12 are at different heights. When multiple temperature sensors 12 are operating, the temperature sensors 12 at different heights measure the liquid temperature at different heights within the preparation tank 1, resulting in more accurate temperature feedback. A viewing window 11 is located on the front of the preparation tank 1. When the preparation equipment is needed, it is placed at the designated workstation using the support legs 8. Then, the external raw material supply equipment is adjusted to discharge a specified amount of deionized water into the preparation tank 1 through the feed pipe 6. Next, solid metal salts such as cobalt isooctanoate and zinc naphthenate are added into the preparation tank 1 through the feed channel 7. At this point, the external raw material supply equipment can be adjusted to heat... Liquid is input into the interior of heating pipe 10 through the lower inlet and then discharged through the upper outlet. The heating liquid continuously circulates inside the heating pipe 10. During the flow of the heating liquid through the heating pipe 10, it dissipates its own heat to the inner wall of the preparation tank 1 and then transfers it to the liquid in the preparation tank 1. At this time, the controller 13 can be controlled to operate the temperature sensor 12. The measuring end of the temperature sensor 12 contacts the liquid in the preparation tank 1. When the temperature inside the preparation tank 1 rises, the metal resistance value increases accordingly. The measuring circuit transmits the collected resistance signal to the controller 13. The controller 13 calculates the corresponding temperature value according to the preset standard formula. Rapid mixing mechanism 4: It includes a support bearing 42, a side rotating rod 43, a side stirring rod 44 (here, the side stirring rod 44 is an anchor-shaped stirring rod), a main rotating rod 45, and a main stirring blade 46 (here, the main stirring blade 46 is an inclined blade-type stirring blade). The main rotating rod 45 is fixedly sleeved in the middle of the rotating plate 3. The main stirring blade 46 is fixedly connected to the lower side of the main rotating rod 45. The left and right sides of the upper surface of the rotating plate 3 are respectively fixedly connected to the support bearing 42. The inner ring surfaces of the two support bearings 42 are respectively fixedly connected to the side rotating rod 43. The lower ends of the two side rotating rods 43 are respectively fixedly connected to the side... The stirring rod 44 and the rapid mixing mechanism 4 also include a gear ring 41 and a gear 47. The gear ring 41 is fixedly connected to the middle of the upper side wall of the top cover 2. The upper ends of the two side rotating rods 43 are respectively fixedly connected to gears 47, and the two gears 47 mesh with a gear ring 41. A motor 5 is fixedly connected to the middle of the upper surface of the top cover 2. The output shaft of the motor 5 is fixedly connected to the upper end of the main rotating rod 45, and the input end of the motor 5 is electrically connected to an external power source. (The rotating plate 3 divides the top cover 2 into two spaces, the upper space of which is sealed, and the transmission parts are located in the upper space to prevent transmission parts from being sealed.) (Contaminated), at this time, the controller 13 can be adjusted to operate the motor 5. The output shaft of the motor 5 rotates, driving the main rotating rod 45 to rotate, which in turn drives the main stirring blade 46 to rotate, which in turn drives the rotating plate 3 to rotate, which in turn drives the two side rotating rods 43 to rotate around the central axis of the main rotating rod 45. During this period, due to the meshing relationship between the gear ring 41 and the two gears 47, the two side rotating rods 43 will also rotate on their own when rotating around the central axis of the main rotating rod 45. At this time, the main stirring blade 46 on the main rotating rod 45 rotates, which will drive the liquid to move around the main stirring blade. Under the action of the stirring blade 46, the fluid flows radially from near the main rotating rod 45 towards the wall of the preparation tank 1. After encountering the boundary layer of the tank wall of the preparation tank 1, it splits into two streams that flow upward and downward respectively, and then return to the blade tip. During this period, some solid metal salt particles are deposited on the lower side of the preparation tank 1. At this time, the outer surface of the side stirring rod 44 agitates the solid metal salt particles. At the same time, during the rotation, the outer surface of the side stirring rod 44 will squeeze the solid metal salt particles between the inner walls of the preparation tank 1, so that the solid metal salt particles are crushed and mixed into the radially flowing water flow with the agitation, and dissolved into the liquid.

[0016] The working principle of the water-based drying agent preparation equipment provided by this utility model is as follows: When the equipment is needed, it is placed in the designated position by the support leg 8. Then, the external raw material supply equipment is adjusted to discharge a specified amount of deionized water into the preparation tank 1 through the feed pipe 6. Then, solid metal salts such as cobalt isooctanoate and zinc naphthenate are added into the preparation tank 1 through the feed channel 7. At this time, the external raw material supply equipment can be adjusted to input the heating liquid into the heating pipe 10 through the lower liquid inlet and then discharged through the upper liquid outlet. The heating liquid continuously circulates inside the heating pipe 10. During the flow of the heating liquid through the heating pipe 10, it will dissipate its own heat to the inner wall of the preparation tank 1 and then transfer it to the liquid in the preparation tank 1. At this time, the controller 13 can be adjusted to activate the temperature sensor 12. The measuring end of the temperature sensor 12 contacts the liquid in the preparation tank 1. When the temperature inside the preparation tank 1 rises, the metal resistance value increases accordingly. The measuring circuit transmits the collected resistance signal to the controller 13. The controller 13 calculates the corresponding temperature according to the preset standard formula. At this point, the controller 13 can be adjusted, the motor 5 will operate, and the output shaft of the motor 5 will rotate, driving the main rotating rod 45 to rotate, which in turn drives the main stirring blade 46 to rotate, which in turn drives the rotating plate 3 to rotate, which in turn drives the two side rotating rods 43 to rotate around the central axis of the main rotating rod 45. During this period, due to the meshing relationship between the gear ring 41 and the two gears 47, the two side rotating rods 43 will also rotate on their own when rotating around the central axis of the main rotating rod 45. At this time, the main stirring blade 46 on the main rotating rod 45 will rotate, which will drive the liquid to move around the main stirring blade. Under the action of 46, the fluid flows radially from near the main rotating rod 45 towards the wall of the preparation tank 1. After encountering the boundary layer of the tank wall of the preparation tank 1, it splits into two streams that flow upward and downward respectively, and then return to the blade tip. During this period, some solid metal salt particles are deposited on the lower side of the preparation tank 1. At this time, the outer surface of the side stirring rod 44 agitates the solid metal salt particles. At the same time, during the rotation, the outer surface of the side stirring rod 44 will squeeze the solid metal salt particles between the inner walls of the preparation tank 1, so that the solid metal salt particles are crushed and mixed into the radially flowing water flow with the agitation, and dissolved into the liquid.

[0017] It is worth noting that the core chip of the controller 13 disclosed in the above embodiments is a single-chip microcomputer, specifically the S7-200. The motor 5 and the temperature sensor 12 can be freely configured according to the actual application scenario. It is recommended that the motor 5 be a Y132S-4 three-phase asynchronous motor, and the temperature sensor 12 be a PT100 type resistance temperature sensor. The controller 13 controls the operation of the motor 5 and the temperature sensor 12 using methods commonly used in the prior art.
