Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a constant temperature mixing device for acrylic varnish. Background Technology

[0002] In the field of coating production, the constant temperature stirring device for acrylic varnish is a key piece of equipment to ensure product quality. This device, through continuous stirring and precise temperature control, ensures that acrylic resin, solvent, and additive raw materials are mixed evenly and maintained at a suitable temperature. This prevents the varnish from curing or deteriorating due to abnormal temperature during the stirring process, ensuring the stability of its performance indicators such as drying speed, gloss, and weather resistance. In industries with stringent requirements for coating quality, such as automotive painting and furniture surface treatment, the mixing uniformity and temperature control accuracy of acrylic varnish directly affect the decorativeness and durability of the final product. Therefore, the performance of this device is of paramount importance.

[0003] Early acrylic varnish constant-temperature stirring devices used a single heating element to directly heat the outer wall of the container, coupled with a common paddle agitator. This structure had significant drawbacks. Firstly, heating with the heating wire caused localized overheating, making it difficult to evenly transfer heat to the inside of the container, resulting in uneven heating of the varnish. This, in turn, affected the compatibility of the resin and solvent, reducing the film quality of the varnish. Secondly, the common agitator had low mixing efficiency for high-viscosity varnishes and could not effectively promote heat transfer. To solve these problems, existing devices use a jacketed constant-temperature structure, indirectly heating through circulating heat transfer oil or water, and have been upgraded to... Multi-layered agitators enhance convection; however, existing devices still have limitations. Due to the gap between the jacket and the container wall, and the uneven flow rate distribution of the heat transfer medium during circulation, the heat transfer efficiency is still insufficient when processing high-viscosity acrylic varnish. Especially in the initial stage of device startup, the outer side of the jacket heats up rapidly, but the varnish inside, due to its high viscosity and poor fluidity, cannot quickly absorb heat through natural convection. This leads to a temperature difference between the central area of ​​the container and the contact area with the jacket, which not only prolongs the overall heating time but also causes localized curing of the varnish due to excessively high local temperatures, affecting product stability.

A hollow rotating rod 205 is rotatably connected to the bottom end of the interior of the mixing tank 5. A hollow stirring assembly 206 is provided at the bottom end of the outer wall of the hollow rotating rod 205. A dispersing assembly 207 is provided in the middle of the outer wall of the hollow rotating rod 205. Multiple L-shaped dispersing blocks 208 are fixedly connected to the top end of the outer wall of the hollow rotating rod 205. A driving assembly 209 is provided at the top end of the cover plate 4.

The outer walls of the perforated mixing blades 2061 are respectively connected to the inner walls of the corresponding connecting holes 2062. The top end of the outer wall of the perforated mixing blades 2061 is fixedly connected to multiple guide strips 2063. When the hollow rotating rod 205 rotates, the perforated mixing blades 2061 installed at the bottom end of its outer wall rotate accordingly. Through the guide strips 2063, the acrylic varnish is pushed to form a strong bottom vortex, enters the perforated mixing blades 2061, and is sprayed out from the holes on the blades, further enhancing the mixing effect.

The middle part of the inner wall of the hollow rotating rod 205 Multiple connecting recesses 2072 are provided, and the outer walls of the multiple connecting recesses 2072 are respectively connected to the outer walls of the corresponding hollow plates 2071.

[0035] Specifically, after the DC motor 2091 is powered on, it begins to rotate at high speed. Through the engaging connection between the engaging post 2092 and the engaging post 2093, power is transmitted to the hollow rotating rod 205, causing it to rotate at high speed. As the hollow rotating rod 205 rotates, the perforated stirring paddle 2061 installed at the bottom of its outer wall rotates accordingly. Through the guide strip 2063, the acrylic varnish is pushed to form a strong bottom vortex, entering the perforated stirring paddle 2061 and being ejected from the holes in the paddle blades, further enhancing the mixing effect. The hollow plate 2071 located in the middle of the hollow rotating rod 205, during rotation, utilizes the internal connecting notch 2072 to connect with the hollow plate 2071. The connecting rod 205 disperses the varnish, breaking up any clumps. The L-shaped dispersing block 208 at the top strikes the liquid surface during rotation, preventing air bubbles from forming and aiding in material dispersion. Simultaneously, the heater 202, when energized, heats the heat-conducting medium in the heating tank 201. The heat is transferred through the heat-conducting cavity 203 and annular heat-conducting ring 204 at the bottom of the mixing tank 5, and also through the connecting hole 2062 and connecting notch 2072 to the perforated stirring paddle 2061 and hollow plate 2071, giving them a certain amount of heat and ensuring that the heat is evenly transferred to the material.

A conical ring 302 is fixedly connected to the bottom end of the outer wall of the cover plate 4. A limiting conical ring 303 is fixedly connected to the top end of the outer wall of the mixing tank 5. Multiple limiting holes 304 are opened at the top end of the mixing tank 5. The cover plate 4 is tightly fixed to the top of the mixing tank 5 through the cooperation of the locking cylinders 301 and the limiting holes 304, and the locking of the conical ring 302 and the limiting conical ring 303, ensuring the sealing of the device during operation.

A feed pipe 306 is connected to the left side of the top end of the cover plate 4. The feed pipe 306 can be used to add raw materials.

[0037] Specifically, the feed pipe 306 can be used to add raw materials, while the automatic exhaust pipe 305 automatically discharges the gas generated by the temperature rise during the stirring process to maintain stable pressure inside the tank. The cover plate 4 is tightly fixed to the top of the mixing tank 5 by the engagement of the locking cylinder 301 and the limiting hole 304, and the engagement of the conical ring 302 and the limiting conical ring 303, ensuring the sealing of the device during operation. When maintenance is required, the cover plate 4 can be moved to the top to release the engagement of the locking cylinder 301 and the limiting hole 304, thereby quickly performing maintenance or cleaning inside the mixing tank 5.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The control component 8 includes a control cabinet 801, the bottom of which is fixedly connected to the top right side of the support plate 1. An operation panel 802 is fixedly connected to the top front of the control cabinet 801. The operation panel 802 sets parameters such as stirring temperature, stirring time, and the speed of the DC motor 2091. These instructions are transmitted to the control system inside the control cabinet 801, which coordinates and controls the operation of the heater 202 and the DC motor 2091. An emergency button 803 is fixedly connected to the bottom front of the control cabinet 801. When the emergency button 803 is pressed, the control cabinet 801 will immediately cut off all power to the device. A warning light 804 is fixedly connected to the top of the control cabinet 801. When the device malfunctions, the sensor inside the control cabinet 801 will send a signal back to the control system. At this time, the warning light 804 will light up red and flash.

[0039] Specifically, parameters such as stirring temperature, stirring time, and DC motor speed 2091 are set via the operation panel 802. These commands are transmitted to the control system inside the control cabinet 801, which coordinates the operation of the heater 202 and DC motor 2091. During operation, the operation panel 802 displays real-time temperature data in the stirring tank 5, the rotation speed of the hollow rotor 205, and the water temperature information in the heating water tank 201, allowing operators to monitor the device's operating status at any time. When an abnormal situation occurs, such as excessive temperature or motor overload, the sensors inside the control cabinet 801 will send a signal back to the control system. At this time, the warning light 804 will light up red and flash, and an alarm will sound to remind the staff that there is a malfunction in the device. In case of emergency, the operator can quickly press the emergency button 803, and the control cabinet 801 will immediately cut off all power to the device, causing the heater 202 to stop heating and the DC motor 2091 to stop rotating, preventing the accident from escalating further.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A filling pipe 7 is connected to the top left side of the heating water tank 201. The filling pipe 7 is connected to the top left side of the heating water tank 201. Its function is to facilitate the operator to add heat transfer medium into the water tank. A discharge pipe 6 is connected to the bottom front side of the mixing tank 5, which can smoothly discharge the evenly mixed acrylic varnish. The outer wall of the locking cylinder 301 is locked with the inner wall of the corresponding limiting hole 304, forming a fastening connection structure between the cover plate 4 and the mixing tank 5. An observation window 9 is fixedly connected to the front side of the mixing tank 5. The observation window 9 is installed on the front side of the mixing tank 5 and is made of a high temperature resistant, high strength and transparent material.

[0041] Specifically, the filling pipe 7 is connected to the top left side of the heating water tank 201. Its function is to facilitate the operator to add heat transfer medium into the water tank. Sufficient heat transfer medium can be injected before the device starts operating, or replenished during operation according to the medium loss, ensuring the continuity and stability of the heat transfer process. The discharge pipe 6 is located at the bottom front of the mixing tank 5, which can smoothly discharge the uniformly mixed acrylic varnish. Because it is located at the bottom of the tank, gravity can be used to assist in the discharge, reducing varnish residue. At the same time, the front position facilitates connection to subsequent conveying pipes or containers, making it convenient to transfer the varnish to the storage tank or use it directly for subsequent spraying processes, realizing high efficiency in the production process. The locking cylinder 301 in the maintenance and filling mechanism 3 cooperates with the limiting hole 304 on the mixing tank 5 to form a tight connection structure between the cover plate 4 and the mixing tank 5. The locking of the outer wall of the locking cylinder 301 and the inner wall of the limiting hole 304 can firmly fix the cover plate 4 to the top of the mixing tank 5, preventing the cover plate 4 from loosening or shifting due to vibration or internal pressure changes during the mixing process. The observation window 9 is installed on the front side of the mixing tank 5 and is made of high temperature resistant, high strength and transparent material. Its main function is to allow the operator to directly observe the mixing status of the acrylic varnish inside the mixing tank 5 without opening the cover plate 4 during the operation of the device.

[0042] Working principle: First, after the DC motor 2091 is powered on, it begins to rotate at high speed. Power is transmitted to the hollow rotating rod 205 through the engaging connection between the engaging concave post 2092 and the engaging post 2093, causing it to rotate at high speed. As the hollow rotating rod 205 rotates, the perforated stirring paddle 2061 rotates synchronously, pushing the acrylic varnish with the help of the guide strip 2063, forming a strong bottom vortex. Meanwhile, the hollow plate 2071 in the middle of the hollow rotating rod 205, during rotation, utilizes its internal connecting notch 2072 and the connection between the hollow plate 2071 and the hollow rotating rod 205 to disperse the varnish, breaking up the polymer... The varnish clumps are dispersed, and the L-shaped dispersing block 208 at the top strikes the liquid surface when rotating, which can prevent the formation of air bubbles on the varnish surface and assist in dispersing the material. At the same time, after the heater 202 is powered on, it heats the heat-conducting medium in the heating water tank 201. The heat is transferred through the heat-conducting cavity 203 and the annular heat-conducting ring 204 at the bottom of the mixing tank 5. At the same time, the heat can also be transferred through the connecting hole 2062 and the connecting notch 2072 to the perforated stirring paddle 2061 and the hollow plate 2071, so that it has a certain amount of heat, thereby ensuring that the heat can be evenly transferred to the material.

[0043] Furthermore, through the maintenance and filling mechanism 3, the feed pipe 306 can be used to add raw materials, and the automatic exhaust pipe 305 automatically discharges the gas generated by the temperature rise during the stirring process to maintain the stability of the pressure inside the tank. The cover plate 4 is tightly fixed to the top of the mixing tank 5 by the cooperation of the locking cylinder 301 and the limiting hole 304 and the locking of the conical ring 302 and the limiting conical ring 303, ensuring the sealing of the device during operation. When maintenance is required, the cover plate 4 only needs to be moved to the top to release the locking cylinder 301 and the limiting hole 304, so that the inside of the mixing tank 5 can be quickly inspected or cleaned.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
