Description

Technical Field

[0001] This utility model relates to the field of constant temperature storage technology, specifically a constant temperature storage device for finished varnish products. Background Technology

[0002] Varnish is a type of paint. Painted varnish can only be used one month after application before moving in. The absence of an irritating odor simply means the formaldehyde levels have reached a physiologically acceptable level. Compared to traditional paints, water-based paints are more environmentally friendly, harmless to the human body, and more suitable. Varnish is typically stored in a constant-temperature storage tank. According to existing technology, such as the circulating constant-temperature storage device for lubricating oil described in Chinese patent document CN202121543776.X, which is easy to clean, a fixed rod is fixedly connected to one end of a screw inside the constant-temperature tank. An installation rod is slidably connected to the fixed rod, and a scraper is rotatably connected to the installation rod. The scraper is tightly attached to the inner wall of the constant-temperature tank, and the upper and lower ends of the scraper's side closest to the inner wall are rounded. A fixed column is fixedly connected to the installation rod. This invention enables automatic cleaning of the tank without opening it, making it convenient to use.

[0003] According to its publicly available technical solutions, in the existing technology, long-term placement of varnish in a constant temperature tank may cause it to harden. At the same time, the temperature control device of the constant temperature tank cannot ensure that the varnish inside is heated evenly, thus making it impossible to accurately control the state of the varnish. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a constant temperature storage device for finished varnish products to solve the problems mentioned in the background technology. This utility model uses a motor-driven stirring device to prevent the varnish from curing, and at the same time uses a fan to drive the heating gas to circulate in the tank and pipes to ensure uniform heating inside.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a constant temperature storage device for finished varnish products, comprising the storage device itself, the storage device including a tank, a stirring device, a heating device and a ventilation device, a motor installed on the top of the tank, the motor being connected to the stirring device via a gear set, an inner tank being provided inside the tank, a first rotating rod connected below the gear set, the first rotating rod being connected to the ventilation device via a toothed belt, and a discharge valve installed on the side of the tank.

[0006] Furthermore, the stirring device includes a stirring rod, an internal pipe, and an air inlet. The air inlet is located on the side of the stirring rod, and the stirring rod is installed inside the internal tank.

[0007] Furthermore, the stirring rod has an internal pipe, and a brush is installed above the internal pipe, with the brush in close contact with the inner wall of the internal tank.

[0008] Furthermore, the air supply device includes a second rotating rod, a fan, and an air supply valve. The top end of the second rotating rod is installed on the top of the tank, and the lower half of the second rotating rod is installed on the top of the inner cavity.

[0009] Furthermore, a fan is installed at the tail end of the second rotating rod, and the air supply valve is installed on the side of the tank.

[0010] Furthermore, the heating device is installed at the bottom of the inner cavity, and the heating device includes a heating rod and a fixing frame.

[0011] Furthermore, a heating rod is installed in the middle of the fixing frame, and the fixing frame is fixedly connected to the inner wall of the tank.

[0012] Furthermore, a temperature sensor is installed inside the discharge valve, and the inner cavity of the inner tank is connected to the inside of the dispensing port.

[0013] The beneficial effects of this utility model are:

[0014] 1. The constant temperature storage equipment for finished varnish products uses a fan to drive the gas heated by the heating device to circulate inside the tank, thereby achieving uniform heating of the internal tank and ensuring that the varnish inside the tank is heated evenly.

[0015] 2. In the constant temperature storage equipment for the finished varnish product, the heated gas circulates inside the tank and the built-in pipes. The high-temperature gas flow, through the high thermal conductivity of the pipe wall metal material, conducts continuous and stable heat exchange with the varnish flowing outside the pipe. This design achieves uniform heating from the inside of the medium by greatly expanding the heat transfer surface area. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides the following technical solution: a constant temperature storage device for finished varnish products, including the storage device itself, the storage device including a tank 4, a stirring device 3, a heating device 20 and a ventilation device 9, a motor 1 installed on the top of the tank 4, the motor 1 being connected to the stirring device 3 through a gear set 7, an inner tank 14 being provided inside the tank 4, a first rotating rod 10 being connected below the gear set 7, the first rotating rod 10 being connected to the ventilation device 9 through a toothed belt 6, a discharge valve 5 being installed on the side of the tank 4, and starting the motor 1, the motor 1 driving the stirring device 3 and the ventilation device 9 to operate.

[0023] In this embodiment, the stirring device 3 includes a stirring rod 13, an internal pipe 18, and an air inlet 17. The air inlet 17 is located on the side of the stirring rod 13. The stirring rod 13 is installed inside the inner tank 14. The stirring rod 13 has an internal pipe 18 inside. A brush 16 is installed above the internal pipe 18. The brush 16 is in close contact with the inner wall of the inner tank 14. After the stirring device 3 is started, the stirring rod 13 agitates the varnish inside, keeping the varnish in motion for a long time and reducing the possibility of curing.

[0024] In this embodiment, the air supply device 9 includes a second rotating rod 12, a fan 11, and an air supply valve 8. The top end of the second rotating rod 12 is installed on the top of the tank body 4, the lower half of the second rotating rod 12 is installed on the top of the inner cavity 22, and the fan 11 is installed at the end of the second rotating rod 12. The air supply valve 8 is installed on the side of the tank body 4. The heating device 20 is installed at the bottom of the inner cavity 22. The heating device 20 includes a heating rod 19 and a fixing frame 21. The heating rod 19 is installed in the middle of the fixing frame 21, and the fixing frame 21 is fixedly connected to the inner wall of the tank body 4. The discharge valve 5 is equipped with a temperature sensor 15. The inner cavity of the inner tank 14 is connected to the inside of the inlet 2. After the air supply device 9 and the heating device 20 are started, the fan 11 sends the air from the air supply valve 8 to the heating device 20, heats it, and then circulates in the inner cavity 22. Some of the heated gas enters the air inlet, fills the built-in pipe 18, and is discharged through the top of the stirring rod 13. By increasing the heating area, the varnish is heated evenly. The internal temperature change is monitored in real time by the temperature sensor 15, which strengthens the control of the varnish state.

[0025] Working principle: After the motor 1 starts, it generates rotational kinetic energy. This mechanical energy is amplified and distributed through the precision meshing gear set 7, forming two parallel energy transmission paths: The main transmission path transmits power vertically to the stirring device 3 immersed in the varnish through the rigidly connected first rotating rod 10. After the stirring rod 13 obtains continuous rotational momentum, its geometric surface generates complex fluid-solid interaction with the high-viscosity varnish fluid, which not only generates effective radial and axial flow splitting motion to break the tendency of fluid internal coagulation, but also inhibits the solidification caused by Brownian motion through continuous shearing action. At the same time, the parallel auxiliary transmission path transmits part of the kinetic energy precisely to the second rotating rod 12 of the air supply device 9 through the flexible toothed belt 6, driving the fan 11 at its end to rotate at high speed. Based on Bernoulli's principle, a stable negative pressure zone is formed in the air inlet 17, continuously drawing ambient air into the system and converting it into a directional high-pressure airflow through the pressure gradient of the fan 11. After entering the heating device 20, the airflow undergoes forced convection heat exchange with the heating rod 19, which operates on the principle of resistance heating. As the air flows over the surface of the heating rod 19, it gains kinetic energy through collisions, and its temperature rapidly rises to a preset value, forming a low-density hot airflow. Driven by buoyancy and forced pressure, the heated airflow circulates along a predetermined path: part of the hot airflow rises along the inner wall of the tank 4 and transfers heat to the inner tank 14 through convection heat exchange; the other part of the hot airflow is forced into the internal pipe 18 of the stirring rod 13 through the air inlet 17 on the side wall of the stirring rod 13 under the action of the system pressure difference. When flowing through the internal pipe 18 of the stirring rod 13, the high-temperature airflow undergoes continuous and stable heat exchange with the varnish flowing outside the pipe due to the high thermal conductivity of the pipe wall metal material. This design achieves a thermal management strategy of uniform heating from the inside of the medium by greatly expanding the heat transfer surface area. After heat exchange, the airflow temperature is moderately reduced and discharged from the top outlet of the stirring rod 13 before re-entering the system's circulating airflow. During this process, the brush 16 installed at the top of the stirring rod 13 maintains mechanical friction with the inner wall of the inner tank 14 with constant contact pressure, which not only continuously removes potential surface scale but also significantly improves the wall heat transfer efficiency by breaking the thermal boundary layer. The thermodynamic balance of the entire system is monitored in real time by a high-precision temperature sensor 15, and the electrical signal generated by it is compared with the preset temperature value through a closed-loop feedback control system, thereby achieving precise adaptive control of the thermal state of the entire system and ensuring that the varnish is always maintained in the optimal storage temperature environment.

[0026] Temperature sensor 15 is an existing mature technology and is not within the protection scope of this utility model. The temperature sensor 15 used in this embodiment refers to a constant temperature storage device for detergent production provided in patent document CN202220628995.6, and the temperature sensor of the constant temperature storage device described in the patent is used to complete the above-mentioned signal transmission and control purposes in this application.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
