Description

Technical Field

[0001] This utility model relates to the field of drying agent preparation technology, specifically a drying agent catalyst reaction device. Background Technology

[0002] A drying agent is a substance that accelerates the drying of a coating film by catalytic oxidation polymerization, shortening the drying time. It is commonly used in oxidative coatings. Practically valuable drying agents include oxides and salts of metals such as cobalt, manganese, lead, iron, zinc, and calcium, as well as their organic acid soaps. Drying agents are prepared using a reaction apparatus. In the prior art, patent publication number CN 215823017 U discloses a catalyst reactor that allows the efficient drying agent CY-7 to fully react. The reactor includes a main body, with legs fixedly connected to the bottom, a cover fixedly connected to the top, a drive motor fixedly connected to the top of the cover, a stirring paddle fixedly connected to the output shaft of the drive motor, a feed pipe and a feed cylinder fixedly connected to the top of the cover, a connecting pipe fixedly connected to the bottom of the feed cylinder, and a receiving tank fixedly connected to the bottom of the connecting pipe. This catalyst reactor, which allows the efficient drying agent CY-7 to fully react, utilizes a connecting pipe, a solenoid valve, a receiving tank, and a pressure pump. The combination of the annular tube and the nozzle allows the catalyst inside the barrel to be evenly sprayed onto the surface of the reactants inside the reactor. Under the action of the stirring paddle, it quickly comes into contact with the reactants, thereby increasing the reaction rate and facilitating its widespread use. In the process of catalytic reaction of the drying agent, the stirring paddle is used to mix the drying agent raw material and the catalyst. However, the stirring paddle has a simple structure and a fixed coverage area for the raw material in the device, which needs improvement. Moreover, the unidirectional rotation of the stirring paddle is prone to generating vortex dead zones, which affects the mixing rate of the drying agent raw material and the catalyst. Therefore, we propose a catalytic reaction device for the drying agent. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a drier catalyst reaction device. This device employs two sets of stirring rods, each of which revolves around the device's axis via a transmission element. By increasing the stirring range, the mixing rate of the drier raw material and catalyst is improved. Simultaneously, the device uses a transmission element to make the two sets of stirring rods rotate in opposite directions, thereby avoiding vortex dead zones caused by unidirectional rotation of the stirring rods. This further improves the mixing rate of the drier raw material and catalyst, accelerates the reaction preparation rate of the drier, and effectively solves the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drying agent catalyst reaction device, comprising a shell, wherein a feed pipe is provided through the upper end of the inner wall of the shell, and a discharge pipe is provided through the conical bottom wall of the shell, and further comprising a mixing mechanism; Mixing mechanism: It includes a first rotating shaft, a rotating rod, a second rotating shaft, a stirring rod, and a transmission assembly.

This device uses two sets of stirring rods. Through the transmission element, each set of stirring rods revolves around the axis of the device. By increasing the stirring range, the mixing rate of the drier raw material and the catalyst is increased. At the same time, the device uses the transmission element to make the two sets of stirring rods rotate in opposite directions, thereby avoiding the vortex dead zone caused by unidirectional rotation of the stirring rods, further improving the mixing rate of the drier raw material and the catalyst, and accelerating the reaction preparation rate of the drier.

[0005] Furthermore, it also includes a microcontroller, which is located outside the housing and its input terminal is electrically connected to an external power supply, facilitating the control of electrical components within the device.

The lower side of the circular shell is rotatably connected to the circular plate via a sealed bearing. The lower side of the circular plate is fixedly connected to the upper side of the rotating rod.

The inner arc wall of the circular shell is equipped with an internal gear ring, which meshes with the gear on the right side, causing a set of stirring elements in the drier catalyst reaction device to rotate in the opposite direction.

[0008] Furthermore, the transmission assembly also includes an external gear ring, which is disposed on the top wall of the cylindrical shell and meshes with the gear on the left side, causing a set of stirring elements inside the drier catalyst reaction device to rotate in the forward direction.

[0009] Furthermore, the mixing mechanism also includes a servo motor, which is located on the upper side of the housing. The input end of the servo motor is electrically connected to the output end of the microcontroller, and the output shaft of the servo motor is fixedly connected to the upper end of the rotating shaft to provide power for the operation of the stirring element inside the drier catalyst reaction device.

[0010] Furthermore, the top wall of the outer shell is provided with an annular tube through a ring of evenly distributed fixing rods. The lower end of the inner wall of the annular tube is provided with evenly distributed through holes. The top wall of the outer shell is provided with a feeding pipe, the lower end of which is connected to the annular tube. This allows the catalyst in the drying catalyst reaction device to be evenly sprayed through the through holes at the bottom of the annular tube.

It also includes a microcontroller 2 located outside the shell 1, with its input terminal electrically connected to an external power source. A solenoid valve 4 is connected in series in the middle of the feed pipe 3, and a solenoid valve 6 is connected in series in the middle of the discharge pipe 5. The input terminals of both solenoid valves 4 and 6 are electrically connected to the output terminal of the microcontroller 2. An annular tube 8 is provided on the top wall of the shell 1 via uniformly distributed fixed rods. Uniformly distributed through holes penetrate the lower end of the inner wall of the annular tube 8. A feed pipe 9 penetrates the top wall of the shell 1, with the lower end of the feed pipe 9... When using the drier catalyst reaction device connected to the annular pipe 8, the microcontroller 2 opens the solenoid valve 4 and uses the feed pipe 3 to transport the drier raw material into the device via an external conveying device. Then, the microcontroller 2 closes the solenoid valve 4 and uses an external gear pump as a power source to transport the catalyst required for the reaction of the drier raw material through an external pipeline via the feed pipe 9 to the annular pipe 8. The catalyst is sprayed downwards in a uniform ring along the through hole at the bottom of the annular pipe 8. By increasing the initial contact range between the catalyst and the drier raw material, the reaction preparation rate of the drier raw material is increased. After the drier preparation is completed, the microcontroller 2 opens the solenoid valve 6 and collects the drier through the discharge pipe 5. The device also includes a mixing mechanism 7. Mixing mechanism 7: It includes a first rotating shaft 71, a rotating rod 72, a second rotating shaft 73, a stirring rod 74, and a transmission assembly 75. The first rotating shaft 71 is rotatably connected to the top wall of the outer casing 1 via a sealed bearing 1. Rotating rods 72 are provided at both the upper and lower ends of the first rotating shaft 71. The two rotating rods 72 are rotatably connected to the second rotating shaft 73, which is symmetrically distributed laterally, via a sealed bearing 2. Stirring rods 74 are provided on the outer side of the second rotating shaft 73. A transmission assembly 75 is provided between the second rotating shaft 73, the upper rotating rods 72, and the outer casing 1. The transmission assembly 75 includes a first fixed rod 751, a circular shell 752, a circular plate 753, a gear 754, and an internal gear ring 755. The circular shell 752 is provided to the top wall of the outer casing 1 via the annularly distributed first fixed rods 751. The lower part of the circular shell 752... A circular plate 753 is rotatably connected to the side via a sealed bearing 3. The lower side of the circular plate 753 is fixedly connected to the upper side of the rotating rod 72 on the upper side. The middle part of the rotating shaft 71 is rotatably connected to the middle parts of the circular shell 752 and the circular plate 753 via a sealed bearing 4. The upper end of the rotating shaft 73 passes through the circular plate 753 and is equipped with a gear 754. The inner arc wall of the circular shell 752 is provided with an internal gear ring 755, which meshes with the gear 754 on the right side. The transmission assembly 75 also includes an external gear ring 756, which is disposed on the top wall of the circular shell 752 and meshes with the gear 754 on the left side. The mixing mechanism 7 also includes a servo motor 76, which is disposed on the upper side of the outer shell 1. The input of the servo motor 76 is... The servo motor 76 is electrically connected to the output of the microcontroller 2. The output shaft of the servo motor 76 is fixedly connected to the upper end of the rotating shaft 71. The microcontroller 2 starts the servo motor 76, causing its output shaft to drive the rotating shaft 71 to rotate in the forward direction. The rotating shaft 71 drives the rotating rod 72 to rotate around its own axis. The rotating rod 72 drives the two rotating shafts 73 and the circular plate 753 to revolve synchronously around the axis of the rotating shaft 71. During the revolve of the left rotating shaft 73 around the device axis, the gear 754 on its upper end meshes with the external gear ring 756, so that the left rotating shaft 73 revolves around the device axis while driving the corresponding stirring rod 74 to rotate in the forward direction around its own axis. The right rotating shaft 73, through the gear 754 on its upper end meshes with the internal gear ring 756, drives the corresponding stirring rod 74 to rotate in the forward direction around its own axis. The meshing connection between 55 allows the right-side rotating shaft 73 to revolve around the device's axis while simultaneously driving the corresponding stirring rod 74 to rotate in the opposite direction around its own axis. The device employs two sets of stirring rods 74, each rotating in opposite directions relative to the device's axis via a transmission element. This increases the stirring range, thereby improving the mixing rate of the drier raw material and catalyst. Simultaneously, the transmission element causes the two sets of stirring rods 74 to rotate in opposite directions relative to each other, avoiding vortex dead zones caused by unidirectional rotation. This further enhances the mixing rate of the drier raw material and catalyst, accelerating the reaction preparation rate of the drier.

[0016] The working principle of the drier catalyst reaction device provided by this utility model is as follows: When using the drier catalyst reaction device, the microcontroller 2 opens the solenoid valve 4, and the drier raw material is transported into the device through the feed pipe 3 using an external feeding device. Then, the microcontroller 2 closes the solenoid valve 4, and then the external gear pump acts as a power source to transport the catalyst required for the reaction of the drier raw material through the external pipeline and the feed pipe 9 to the annular pipe 8. The catalyst is sprayed downwards in a ring shape along the through hole at the bottom of the annular pipe 8. By increasing the initial contact range between the catalyst and the drier raw material, the reaction preparation rate of the drier raw material is increased. At the same time, during this process, the microcontroller 2 starts the servo motor 76, which causes its output shaft to drive the rotating shaft 71 to rotate in the forward direction. The rotating shaft 71 drives the rotating rod 72 to rotate around its own axis. The rotating rod 72 drives the two rotating shafts 73 and the circular plate 753 to revolve synchronously around the axis of the rotating shaft 71. The rotating shaft 73 on the left revolves around the axis of the device. In the process, the gear 754 at its upper end meshes with the external gear ring 756, causing the left rotating shaft 73 to revolve around the device's axis while simultaneously driving the corresponding stirring rod 74 to rotate in the forward direction around its own axis. The right rotating shaft 73, through the meshing connection between its upper gear 754 and the internal gear ring 755, also causes the right rotating shaft 73 to revolve around the device's axis while simultaneously driving the corresponding stirring rod 74 to rotate in the reverse direction around its own axis. The simultaneous revolve and opposite rotation of the two stirring rods 74 around the device's axis increases the mixing range and speed of the drier raw materials. Simultaneously, the opposite rotation of the two stirring rods 74 prevents the formation of edging vortices, further enhancing the mixing speed of the drier raw materials and thus increasing the drier preparation rate. After the drier preparation is complete, the microcontroller 2 opens the solenoid valve 6, collecting the drier through the discharge pipe 5.

[0017] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM8S, the solenoid valve 4 and the solenoid valve 6 can both be ZCT-16, the servo motor 76 can be a TLMO-200-13C50B2A, and the microcontroller 2 controls the operation of the solenoid valve 4, the solenoid valve 6 and the servo motor 76 using methods commonly used in the prior art.
