Description

Technical Field

[0001] This invention relates to glue boiling technology, and particularly to a sealed glue boiling heating tank. Background Technology

[0002] Currently, in the field of rubber testing, it is necessary to process the sampled rubber latex into samples suitable for analysis. The first step in this process is called "boiling," which involves manually extracting the liquid latex into a solid sample. The existing boiling process involves manually collecting a certain amount of latex through a sample container 1, then introducing high-temperature steam through a steam pipe 2 in an outdoor location. This causes the water and other chemical substances in the latex to evaporate, ultimately yielding a solid sample. The operational principle is illustrated in the diagram below. Figure 1 As shown. Existing glue-boiling processes have the following problems: 1. Open-air glue boiling, where harmful chemicals produced during the process volatilize into the atmosphere, polluting the environment; 2. The glue-boiling process requires manual supervision, and the released harmful gases can harm human health; 3. The glue-boiling process requires manual operation of the high-temperature steam pipe, which poses safety hazards if not operated properly; 4. Sample residue remains in the barrel after the glue-boiling process, which is difficult to clean. In view of this, the inventors of this application, through in-depth research, have developed an environmentally friendly closed glue-boiling device. Summary of the Invention

[0013] In a preferred embodiment, the bottom of the bucket lid is provided with a gas absorption device, which includes a fixing ring, multiple absorption tubes and a main pipe. The fixing ring has a cavity inside and is installed at the bottom of the bucket lid. The multiple absorption tubes are evenly spaced and fixed at both ends to the fixing ring.

A heating chamber 28 is formed between the outer wall of the inner tank 5 and the inner wall of the outer tank 16. The heating chamber 28 is provided with a heat medium inlet 29 and a heat medium outlet 32. The heat medium inlet 29 is connected to... The device includes a heat transfer valve 31, a lid 17 mounted on the inner drum 5, a water inlet pipe 6 and a gas outlet 8 on the side of the inner drum 5, a water inlet valve 7 on the water inlet pipe 6, a drain pipe 9 at the bottom of the inner drum 5, a drain valve 11 on the drain pipe 9, a condensation device 38 connected to the gas outlet 8, a waste gas recovery tank 40 connected to the condensation device 38, a liquid pump 39 connected to the waste gas recovery tank 40, and a vacuum generator 43 connected to the inner drum 5. The heat transfer valve 31, the water inlet valve 7, the drain valve 11, the condensation device 38, the liquid pump 39, the waste gas recovery tank 40, and the vacuum generator 43 are all electrically connected to the human-machine interface touch screen 37.

[0030] This embodiment describes an environmentally friendly, sealed glue-cooking device. Its working process is as follows: First, a certain amount of tap water is added to the glue-cooking tank 4 via the water inlet valve 7, which can be achieved through buttons on the explosion-proof electrical control cabinet 3 or the human-machine interface touchscreen 37; then, the tank lid 17 is opened, the glue sample is added, and then the lid 17 is closed; the task is started; the system begins to open the heat medium valve 31 to automatically introduce the heat medium. The heat medium can be steam or heat transfer oil. If the heat source is steam, the steam flow rate can be controlled through the heat medium valve 31 to control the temperature inside the tank. This control valve can be a proportional valve.

[0031] Compared with existing technologies, the environmentally friendly closed glue-cooking equipment of this embodiment has the following advantages: 1. It adopts a closed glue-cooking method, which is very environmentally friendly. The harmful chemicals generated during the glue-cooking process will not be released into the atmosphere, and these chemicals are condensed and recovered at the same time; 2. It adopts a jacketed indirect heating glue-cooking method, which is highly efficient and the heating is more uniform; 3. The equipment can choose between steam heating or heat transfer oil heating, which is highly flexible. If steam heating is selected, the whole machine can also be explosion-proof; the glue-cooking function is completed automatically without manual operation; the equipment can be expanded into a fully automatic glue-cooking method: that is, automatic opening and closing of the barrel lid 17, automatic addition of glue liquid, and automatic cleaning of the inner barrel 5.

[0032] An environmentally friendly, sealed glue-cooking equipment according to this embodiment also includes an electrostatic discharger 44, which is located outside the explosion-proof electrical control cabinet 3 and is used to release static electricity.

[0033] An environmentally friendly, sealed glue-cooking device according to this embodiment also includes a vacuum breaking valve. The vacuum breaking valve is located on the connection passage between the vacuum generating device 43 and the inner barrel 5 to prevent negative pressure from being generated inside the glue-cooking barrel 4 due to excessive air extraction, which would prevent the lid from being opened.

[0034] The vacuum generating device 43 can be configured as a vacuum generator or a vacuum pump.

[0035] To ensure timely discharge of waste liquid, the waste gas recovery tank 40 is equipped with a level gauge 42. When the collected liquid substance reaches a certain amount, it is discharged through the drain valve 41. If it needs to be pumped away, a liquid pump 39 is used to pump the waste liquid to a designated point. The liquid pump 39 can be specifically configured as a diaphragm pump.

[0036] To facilitate a sealed connection, the heat medium inlet 29 is provided with an inlet flange 30, the heat medium outlet 32 ​​is provided with an outlet flange 33, and the drain pipe 9 is provided with a drain flange 10.

[0037] In order to monitor the temperature and pressure during the glue boiling process, the inner barrel 5 is also provided with a temperature sensor mounting tube 12 and a pressure gauge mounting tube 13 on its side. The temperature sensor mounting tube 12 is equipped with a temperature sensor, and the pressure gauge mounting tube 13 is equipped with a pressure gauge.

[0038] To improve the structural strength of the heating cavity 28, a support plate 36 is provided in the heating cavity 28.

[0039] To achieve orderly flow of the heat medium, the top of the inner barrel 5 is provided with a liquid receiving ring 14, the barrel cover 17 is installed on the liquid receiving ring 14, the bottom of the liquid receiving ring 14 is provided with a drain pipe 15, and the heating chamber 28 is provided with a spiral plate 34. The spiral plate 34 surrounds the inner barrel 5 and forms a heat medium channel 35 in the heating chamber 28. The heat medium inlet 29 and the heat medium outlet 32 ​​are respectively connected to the beginning and end of the heat medium channel 35. The spiral arrangement makes the heating more uniform.

[0040] To achieve uniform and complete absorption of exhaust gas inside the container, a gas absorption device is provided at the bottom of the container lid 17. This device includes a fixing ring 19, multiple absorption tubes 20, and a main pipe 21. The fixing ring 19 has an internal cavity and is installed at the bottom of the container lid 17. The multiple absorption tubes 20 are evenly spaced and fixed at both ends to the fixing ring 19. The absorption tubes 20 and the main pipe 21 connect to the cavity. Multiple suction holes are provided on the walls of the absorption tubes 20. The main pipe 21 also connects to the gas outlet 8. With this structure, the multiple absorption tubes 20 cover the top area of ​​the inner container 5. When exhaust gas is generated, it is drawn into the absorption tubes 20. After passing through the absorption tubes 20, the cavity, and the main pipe 21, the exhaust gas enters the gas outlet 8 and is discharged. This prevents the exhaust gas from randomly moving and stagnating inside the container, ensuring timely discharge and preventing it from overflowing from the gap between the container lid 17 and the inner container 5, thus further reducing the possibility of environmental pollution.

[0041] Furthermore, a rotating hinge is provided between the bucket lid 17 and the inner bucket 5. The absorption tube 20 is spiral-shaped, and its length direction is parallel to the rotation plane of the bucket lid 17. A plurality of mounting grooves 18 are provided on the lower surface of the bucket lid 17. The plurality of mounting grooves 18 are arranged between the plurality of absorption tubes 20 in a straight line. A toggle guide 22 is provided in the mounting groove 18. The toggle guide 22 includes a bracket 23, a rotating shaft 24, a counterweight 25, and a toggle claw. The rotating shaft 24 is provided on the bracket 23. The counterweight 25 and the toggle claw are respectively provided at both ends of the bracket 23. The toggle claw includes a body 26 and a plurality of levers 27. The levers 27 are parallel to the rotating shaft 24. The rotating shaft 24 is installed in the mounting groove 18. During the glue boiling process, the bucket lid 17 is in a horizontal position. Under its own weight, the counterweight 25 extends out of the mounting groove 18, acting as a guide plate, causing the airflow to move along the length of the absorption pipe 20. This allows the exhaust gas to be quickly absorbed by the absorption pipe 20. During the opening process, due to the weight of the counterweight 25, it remains in the lower position of the agitator 22, causing the bucket lid 17 to rotate relative to the agitator. As the bucket lid 17 rotates, the counterweight... 25 gradually enters the mounting groove 18, and the actuating claw gradually extends out of the mounting groove 18. The actuating claw extending out of the mounting groove 18 actuates the absorption tube 20. Specifically, the actuating rod 27 actuates the absorption tube 20, causing the absorption tube 20 to vibrate, thereby shaking off the water condensed on the absorption tube 20. At the same time, the vibration of the absorption tube 20 also causes the bucket lid 17 to vibrate, so that the water condensed on the lower surface of the bucket lid 17 can also be shaken off, thereby preventing the condensed water from entering the bucket during the next glue boiling.

[0042] By setting the absorption pipe 20 in a spiral shape, more absorption holes can be set on the absorption pipe 20 to achieve more uniform and sufficient absorption of exhaust gas. In addition, the shaking effect can be enhanced to ensure that the condensate is fully shaken off.
