Description

Technical Field

[0001] This utility model belongs to the technical field of dehydration equipment, and specifically relates to a low-temperature epoxy adhesive dehydration device. Background Technology

[0002] Low-temperature epoxy adhesive dehydration equipment is an industrial device specifically designed to remove residual moisture or solvents from epoxy resin adhesives. Its core function is to achieve efficient dehydration through physical or chemical means under low-temperature conditions, while avoiding the damage to the epoxy resin molecular structure caused by high temperatures. Such devices typically consist of a vacuum system, a temperature control unit, a reaction vessel, a condensation recovery device, and an intelligent control system. Existing low-viscosity epoxy resin mixing devices suffer from significant defects in dispersing micron-sized encapsulated water due to the lack of dynamic shear field design. The core problem stems from the insufficient adaptability of traditional stirring structures to the hydrodynamic characteristics of low-viscosity systems. The laminar flow field generated by conventional propellers or anchor stirrers cannot form an effective shear gradient, making it difficult for water within the resin phase to overcome interfacial tension and migrate, resulting in the retention of inclusions. Therefore, a new structure is proposed to solve these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-temperature epoxy adhesive dehydration device to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a low-temperature epoxy adhesive dehydration device, comprising: a lifting tray and a stirring assembly, wherein the lifting tray is located below the inner side of the main body of the dehydration device, a stirring tank is placed above the inner side of the lifting tray, and a stirring assembly is provided inside the stirring tank.

[0005] The stirring assembly includes a drive shaft and a stirring component. The stirring component includes a connecting plate for connecting and fixing the stirring blades and the connecting sleeve. An electric heating plate is embedded inside the lifting tray.

[0006] In a preferred embodiment, a control base is provided below the main body of the dehydration equipment, and a hydraulic cylinder for driving the lifting tray to move up and down is installed inside the control base.

[0007] The top of the hydraulic cylinder passes through the bottom of the dehydration equipment body via a telescopic rod and is fixed to the center of the bottom of the lifting tray. A top cover is installed on the top of the dehydration equipment body, and a drive motor is installed on the top cover. A temperature sensor is installed on the right side of the drive motor.

[0008] In a preferred embodiment, the radius of the lifting tray matches the radius of the inner side of the dehydration equipment body, and the lifting tray has a U-shaped structure, with the radius of the downward-recessed portion at the top of the lifting tray matching the radius of the mixing tank.

[0009] In a preferred embodiment, the height of the mixing tank is less than the depth of the main body of the dewatering equipment, and the bottom of the mixing tank is fixed to the upper surface of the lifting tray by bolts.

[0010] In a preferred embodiment, the bottom output end of the drive motor is connected to the top of the transmission shaft below it via a coupling, and a heating mechanism for accelerating dehydration is installed inside the main body of the dehydration equipment.

[0011] The heating mechanism includes an electric heating wire, and the temperature sensor extends downward into the upper part of the dehydration device.

[0012] In a preferred embodiment, the drive shaft extends downward to the inner side of the dewatering equipment body, and two sets of stirring assemblies are installed on the outer side below the drive shaft. The inner side of the connecting sleeve in the stirring assembly is fixed to the outer side of the drive shaft.

[0013] In a preferred embodiment, a connecting plate is welded to each of the four sides of the connecting sleeve. The four connecting plates are arranged symmetrically around the center of the connecting sleeve, and the angle between the connecting plate and the horizontal plane is 30 degrees.

[0014] In a preferred embodiment, a set of stirring blades is fixed to the side of the connecting plate away from the connecting sleeve by four bolts, and the tilt angle of the stirring blades is the same as the tilt angle of the connecting plate.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a lifting tray and a stirring assembly, the bottom of the lifting tray is connected to the hydraulic cylinder inside the control base through a telescopic rod. A stirring tank is installed on the inner side of the upper surface of the lifting tray. The stirring tank is equipped with a drive shaft and two sets of upper and lower stirring assemblies. The stirring assembly includes four sets of stirring blades. In actual use, the drive shaft drives the two sets of stirring assemblies to stir the low-temperature epoxy adhesive liquid inside the stirring tank. The upper stirring assembly can stir the upper half of the low-temperature epoxy adhesive liquid, and the lower stirring assembly can stir the lower half of the low-temperature epoxy adhesive liquid. Then, the lifting tray pushes the stirring tank to move up and down at a constant speed repeatedly under the repeated up and down movement of the telescopic rod. Therefore, while keeping the positions of the drive shaft and the two sets of stirring assemblies fixed, the up and down movement of the low-temperature epoxy adhesive liquid is achieved by the up and down displacement of the stirring tank. This provides a dynamic shear force field, which greatly increases the shear force of the stirring assembly and improves the dehydration efficiency.

[0016] 2. By setting up a lifting tray, an electric heating plate is embedded inside the lifting tray. The electric heating plate is connected to the power supply mechanism inside the control base through wires. At the same time, a heating mechanism for accelerating dehydration is set inside the dehydration equipment. The heating mechanism includes electric heating wires, and a temperature sensor extends downward into the upper part of the dehydration equipment. Therefore, the temperature sensor can monitor the temperature inside the main body of the dehydration equipment in real time. Without damaging the properties of the low-temperature epoxy adhesive, the low-temperature epoxy adhesive can be appropriately heated to accelerate the removal of water. At the same time, the electric heating plate can provide auxiliary heating to the bottom of the mixing tank, thereby improving the dehydration efficiency. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-4 As the first embodiment of this utility model: a low-temperature epoxy adhesive dehydration device, including: a lifting tray 220 and a stirring assembly 300. The lifting tray 220 is located below the inner side of the dehydration equipment body 100, and a stirring tank 130 is placed above the inner side of the lifting tray 220. The stirring assembly 300 is provided inside the stirring tank 130.

[0027] The stirring assembly 300 includes a drive shaft 310 and a stirring component 320. The stirring component 320 includes a connecting plate 322 for connecting and fixing the stirring blade 323 and the connecting sleeve 321. An electric heating plate is embedded inside the lifting tray 220.

[0028] A control base 200 is provided below the main body 100 of the dewatering equipment. A hydraulic cylinder for driving the lifting tray 220 to move up and down is installed inside the control base 200.

[0029] The top of the hydraulic cylinder passes through the bottom of the dewatering equipment body 100 via a telescopic rod 210 and is connected and fixed at the center of the bottom of the lifting tray 220. A top cover is installed on the top of the dewatering equipment body 100, and a drive motor 110 is installed on the top cover. A temperature sensor 120 is installed on the right side of the drive motor 110.

[0030] The radius of the lifting tray 220 matches the radius of the inner side of the dewatering equipment body 100, and the lifting tray 220 has a U-shaped structure. The radius of the downward-concave part at the top of the lifting tray 220 matches the radius of the mixing tank 130.

[0031] The height of the mixing tank 130 is less than the depth of the main body 100 of the dewatering equipment, and the bottom of the mixing tank 130 is fixed to the upper surface of the lifting tray 220 by bolts.

[0032] The drive shaft 310 extends downward to the inner side of the dewatering equipment body 100. Two sets of stirring components 300 are installed on the outer side below the drive shaft 310. The inner side of the connecting sleeve 321 in the stirring component 300 is fixed to the outer side of the drive shaft 310.

[0033] A connecting plate 322 is welded to each of the four sides of the connecting sleeve 321. The four connecting plates 322 are arranged symmetrically around the center of the connecting sleeve 321, and the angle between the connecting plate 322 and the horizontal plane is 30 degrees.

[0034] A set of stirring blades 323 is fixed to the side of the connecting plate 322 away from the connecting sleeve 321 by four bolts. The tilt angle of the stirring blades 323 is the same as the tilt angle of the connecting plate 322.

[0035] In actual use, the mixing tank 130 is filled with a low-viscosity epoxy adhesive. The mixing tank 130 is located inside the main body 100 of the dewatering equipment, and the main body 100 and its top cover work together to create a sealed environment inside. During use, the drive motor 110 drives the transmission shaft 310 to rotate, which in turn drives the two sets of mixing components 300 below to rotate. Thus, the two sets of mixing components 300 rotate in the upper and lower sections of the epoxy adhesive, respectively. The distance between the bottom of the lower mixing component 300 and the lower inner surface of the mixing tank 130 is one-third of the depth of the mixing tank 130. This design is intended to provide sufficient space for the lifting tray 220 to move the mixing tank 130 up and down. Then, the hydraulic cylinder can drive the telescopic rod 210 to push and pull the lifting tray 220 upwards (hydraulic cylinder and drive motor). 110 are all existing technologies, and their models can be selected according to the models available on the market (not described in detail). The lifting tray 220 drives the mixing tank 130 above it to move up and down at a uniform speed along the inner side of the dewatering equipment body 100. Since the positions of the drive shaft 310 and the two sets of mixing components 300 are fixed, the mixing tank 130 moves up and down under the drive of the lifting tray 220. Therefore, the mixing tank 130 can drive the low-viscosity epoxy adhesive inside it to move up and down, thereby changing the relative position of the two sets of mixing components 300 inside the low-viscosity epoxy adhesive. Therefore, the final effect is that the continuous up and down movement of the lifting tray 220 can drive the low-viscosity epoxy adhesive to continuously change the relative position between it and the two sets of mixing components 300, thereby providing a dynamic shear force field, increasing the shear force of the mixing components 300, and improving the dewatering efficiency.

[0036] Please see Figures 1-4 As a second embodiment of this utility model: based on the description in the above embodiments, further, the bottom output end of the drive motor 110 is connected to the top of the transmission shaft 310 below it through a coupling, and a heating mechanism for accelerating dehydration is installed inside the main body 100 of the dehydration equipment.

[0037] The heating mechanism includes an electric heating wire, and a temperature sensor 120 extends downward into the upper part of the dehydration device.

[0038] In actual use, the heating mechanism installed inside the main body 100 of the dehydration equipment can appropriately heat the low-temperature epoxy adhesive for dehydration without damaging its properties, thus promoting the dehydration process. The specific temperature is maintained between 60 and 80 degrees Celsius. Within this temperature range, the dehydration efficiency can be improved without damaging the properties of the low-temperature epoxy adhesive. During this period, the temperature inside the main body 100 of the dehydration equipment is monitored and controlled in real time by the temperature sensor 120 (the temperature sensor 120 and the heating mechanism are existing technologies, and their internal structure and working principle will not be described in detail here). During this period, the electric heating plate installed inside the lifting tray 220 can provide auxiliary heating to the bottom of the mixing tank 130. This is because the bottom of the mixing tank 130 is less susceptible to heat penetration than the inner wall above it. Therefore, the electric heating plate inside the lifting tray 220 can provide auxiliary heating to the bottom of the mixing tank 130, accelerating the removal of water and thus helping to improve the dehydration efficiency.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
