Description

Technical Field

[0001] This utility model relates to the field of rosin dissolving technology, and in particular to a rosin dissolving device with waste gas collection function. Background Technology

[0002] Rosin's main component is resin acid, which possesses excellent chemical stability and unique physical properties, thus finding important applications in numerous industries. Currently, rosin is no longer merely a raw material but plays a crucial role in industrial production as a highly efficient modifier and additive. In the coatings, inks, and paints industries, rosin improves product adhesion, abrasion resistance, and weather resistance, enhancing the overall performance of coatings. In the adhesives field, rosin strengthens bond strength and is suitable for bonding various materials such as wood and paper. In soldering fluxes, rosin helps improve welding efficiency and ensures weld quality. In the rubber industry, rosin acts as a plasticizer and softener, improving the processing and physical properties of rubber. In the paper industry, rosin is used in paper sizing to improve the paper's water resistance. In the biopharmaceutical field, the applications of rosin are also expanding, such as as a modifier for biomedical materials.

[0003] However, in the existing technology, rosin needs to be cooled to 200 degrees Celsius by a water cooling system before it can be discharged. During this process, the heat carried away by the water is not effectively utilized, which not only causes a direct loss of energy but also increases production costs and reduces energy efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1 , Figure 3 and Figure 4A rosin dissolving device with waste gas collection function includes a dissolving container 1 and a jacket 2. The jacket 2 is fitted around the outer periphery of the dissolving container 1. A feed pipe 3 communicating with the inner cavity of the dissolving container 1 is installed at the top of the dissolving container 1. An exhaust pipe 4 communicating with the inner cavity of the dissolving container 1 is also installed at the top of the dissolving container 1. An outlet 5 is opened at the bottom of the dissolving container 1. A heating component 6 is arranged inside the jacket 2. The device also includes a cold water tank assembly 7 and a heating water tank assembly. The cold water tank assembly 7 is provided with two output ends. Each of the two output ends is connected to a first connecting pipe 8 and a second connecting pipe 9 through a pump body. The pipes 9 are respectively arranged in a spiral winding manner on the outer periphery of the dissolving container 1 and the exhaust pipe 4, and the other ends of the first connecting pipe 8 and the second connecting pipe 9 are connected to the heating water tank assembly. The heating water tank assembly is provided with an output end, and the output end of the heating water tank assembly is equipped with a third connecting pipe 10 for outputting hot water. The first connecting pipe 8 is made of alumina ceramic, stainless steel or polytetrafluoroethylene, etc., which can maintain a good working effect under the heating of the heating component 6. The heating component 6 is a heating coil, and the heating coil and the first connecting pipe 8 are alternately wound or staggered in a position where one is inside and the other is outside, so that they will not interfere with each other.

[0021] In this embodiment, the rosin dissolving device is used alone. The other end of the third connecting pipe 10 is connected to the first connecting pipe 8. After the first connecting pipe 8 and the second connecting pipe 9 recover the heat from the exhaust pipe 4 and the dissolving container 1 to the heating water tank assembly through the pump body, when the next rosin dissolving is required, the water in the heating water tank body 11 can be reintroduced into the first connecting pipe 8 through the second water pumping assembly 12 to preheat the rosin dissolving process inside the dissolving container 1. The water after heat exchange then re-enters the cold water tank assembly 7.

[0022] When this device is in use, after the rosin in the dissolving container 1 is completely dissolved, it moves from the heat preservation stage to the cooling stage (after the rosin is completely melted, during the stirring process, auxiliary materials other than rosin need to be added to the dissolving container 1, and the temperature is raised to the specified reaction temperature (generally 230~270℃) and kept at that temperature for a period of time. After the temperature is kept at that temperature, samples are taken to test various product indicators. After the test is qualified, water cooling is performed and vacuum degassing is started (vacuum degassing is a subsequent process of this device and is not shown in this device)). Water is supplied to the first connecting pipe 8 and the second connecting pipe 9 through the two output ends of the cold water tank assembly 7 to cool the dissolving container 1. Then, the water that has absorbed the heat is allowed to enter the heating water tank assembly for storage. When this device performs the next rosin dissolution, it can first use the water that has absorbed the heat stored in the heating water tank assembly to preheat the inside of the dissolving container 1, and then heat it through the heating assembly 6. This can reduce energy consumption and solve the problem that the heat is not effectively utilized and the energy utilization efficiency is reduced in the prior art.

[0023] Furthermore, the heating water tank assembly includes a heating water tank body 11 and a second water pumping assembly 12 disposed on one side of the heating water tank body 11. One end of the third connecting pipe 10 is installed at the output end of the second water pumping assembly 12. Through the second water pumping assembly 12, the hot water in the heating water tank body 11 can be reintroduced into the first connecting pipe 8 to preheat the dissolving container 1.

[0024] Furthermore, a stirring assembly is installed at the top of the dissolving container 1. The stirring assembly includes a mounting frame 13 at the top of the dissolving container 1, a rotary motor 14 mounted on the mounting frame 13, and a rotating rod 15 mounted at the drive end of the rotary motor 14. The rotating rod 15 moves through the dissolving container 1, and several stirring rods 16 are installed on the outer periphery of the rotating rod 15 for stirring the rosin in the dissolving container 1. When the heating assembly 6 heats the container, the rotary motor 14 can drive the rotating rod 15 to rotate, thereby driving the stirring rods 16 on the outer periphery of the rotating rod 15 to rotate and stir the rosin, so that the rosin is dissolved evenly.

[0025] Furthermore, a connecting plate 17 is installed at the bottom of the dissolving container 1, a third pumping assembly 18 is provided on one side of the cold water tank assembly 7, and the output end of the third pumping assembly 18 is connected to a first outlet pipe 19. A first inlet pipe 20 is installed on one side of the heating water tank body 11. A cavity 21 is opened inside the rotating rod 15, and a diverter plate 25 is vertically installed in the cavity 21, dividing the cavity 21 into two parts. One end of the first outlet pipe 19 and the first inlet pipe 20 are both semi-circular. The ends of the first outlet pipe 19 and the first inlet pipe 20 are joined together to form a circle, and the joined ends of the first outlet pipe 19 and the first inlet pipe 20 rotate with the rotating rod 15 through a sealed bearing. The connection is made so that the output and input ends of the first water outlet pipe 19 and the first water inlet pipe 20 are located on both sides of the diversion plate 25, and the height of the diversion plate 25 is lower than the height of the cavity 21. Through the third water pumping component 18, the water in the cold water tank component 7 can enter the cavity 21 through the first water outlet pipe 19 and the sealed bearing. The continuous water injection causes the water level in the cavity 21 to rise. When the water exceeds the diversion plate 25, the water can carry away the heat in the rosin and enter the heating water tank body 11 through the first water inlet pipe 20 for storage. When the water in the two pipes flows in opposite directions, heat feedback is achieved. The stirring rod preheats the dissolving container 1. At this time, both the third water pumping component 18 and the pump body must be bidirectional water pumps.

[0026] Furthermore, valves 22 are installed on the first connecting pipe 8, the third connecting pipe 10, and the first water inlet pipe 20, and the opening and closing of the first connecting pipe 8, the third connecting pipe 10, and the first water inlet pipe 20 are controlled by the valves 22.

[0027] Furthermore, a fan 23 is installed at one end of the exhaust pipe 4 to draw in water vapor and gas generated from the dissolution of rosin in the dissolving container 1, collect the waste gas, and send the waste gas into the waste gas treatment device. In this embodiment, the waste gas treatment device can be a catalytic combustion system.

[0028] The fan 23 can discharge the water vapor generated in the dissolving container 1 when the heating component 6 is heating. When rosin needs to be discharged (when the heating temperature is greater than 250 degrees, the cracking reaction will be intensified, producing harmful substances such as carbon black and polycyclic aromatic hydrocarbons (PAHs)), the fan 23 is started to drive the waste gas in the dissolving container 1 to flow. The waste gas is filtered first by the activated carbon filter plates set in front of and behind the fan 23. After filtration, the waste gas can be discharged into the catalytic combustion system through the pipeline for treatment to prevent greater pollution. Example

[0029] The difference between this embodiment and Embodiment 1 is that:

[0030] In this embodiment, multiple rosin dissolving devices are arranged for simultaneous use (not shown in the figure);

[0031] In this embodiment, the output end of the heating water tank assembly is equipped with a third connecting pipe 10 for outputting hot water, and the third connecting pipe 10 is connected to the first connecting pipe 8 of another rosin dissolving device, so that hot water can be directly supplied to the other rosin dissolving device for preheating.

[0032] In this embodiment, the heating water tank assembly further includes an electric heating component 24 disposed within the heating water tank body 11 (such as...). Figure 2 As shown in the figure, the electric heating component 24 can reheat the water after it has absorbed heat, thereby increasing the heat of the water and preventing the water from being too hot to complete the preheating. At the same time, the auxiliary heating coil heats the dissolving container. The electric heating component 24 can be monitored by the set temperature sensor, and its temperature rise and fall can be controlled according to its real-time temperature. After the heating is completed, the water is transported to the outer periphery of the dissolving container 1 to preheat the dissolving container 1.

[0033] The temperature sensor is a thermocouple or resistance temperature detector (RTD), etc. The temperature sensor is in contact with or close to the electric heating component 24 to accurately measure its temperature. The temperature sensor can convert the temperature into an electrical signal (voltage or resistance value), and the temperature rise and fall control of the electric heating component 24 can be realized through the control processor. This temperature sensor is existing technology and will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
