Description

Technical Field

[0001] This utility model relates to the field of heating kettle technology, specifically a heating kettle for processing calcium stearate with a pressure relief structure. Background Technology

[0002] The heating reactor for calcium stearate processing is a key piece of equipment in the calcium stearate production process, mainly used for heating the reaction of stearic acid with calcium hydroxide (or calcium oxide) and subsequent salt formation. In the synthesis of calcium stearate, the heating reactor provides a stable thermal environment for the material reaction through precise temperature control, which is crucial for ensuring product purity, reaction efficiency, and subsequent processing performance. In the industrial production system of calcium stearate, the heating reactor is the core carrier of the reaction section—it maintains a suitable temperature (typically 120℃-150℃) through heat transfer, promoting the full reaction of stearic acid and alkaline calcium source to generate calcium stearate intermediates, and ensuring the stable progress of subsequent dehydration and purification steps through continuous temperature control. This equipment directly affects the final properties of calcium stearate, such as dispersibility, lubricity, and compatibility with polymer materials, thus influencing its application in plastics, rubber, coatings, and other fields.

[0003] As a fundamental piece of equipment in chemical production, the operational stability and process adaptability of heating reactors play a decisive role in the product quality of calcium stearate. Their temperature control precision and thermal efficiency not only affect the reaction rate and conversion rate but also directly impact energy consumption and production costs. With the expanding applications of calcium stearate in high-end plastics modification and environmentally friendly coatings, heating reactors are being optimized for more precise temperature control and more uniform heat field distribution to meet the stringent requirements of different formulations and processes. They are crucial technical equipment for ensuring the continuity, efficiency, and consistency of calcium stearate production.

[0004] The heating kettle used for calcium stearate processing suffers from a significant problem during operation: the pressure relief process is cumbersome and the response is slow, preventing the rapid release of high-pressure gas or steam. This directly impacts production safety, especially during abnormal overpressure reactions. Delayed pressure relief prolongs the duration of the dangerous situation, increasing the risk of equipment cracking and seal failure. It also increases safety hazards for operators, complicates emergency response, and reduces the reliability and controllability of the production process. Utility Model Content

[0005] The purpose of this invention is to provide a heating kettle for processing calcium stearate with a pressure relief structure, which solves the problem that it is inconvenient to relieve pressure when using a heating kettle for processing calcium stearate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heating vessel for processing calcium stearate with a pressure relief structure, comprising a vessel body, a sleeve fixedly connected inside the vessel body, a mounting base fixedly connected to the lower end of the sleeve, a fixing tube fixedly connected inside the mounting base, the fixing tube being fixedly connected to the sleeve, a connecting tube inserted into the outer side of the fixing tube, a sliding rod slidably connected inside the sleeve, a sealing gasket fixedly connected to the side of the sliding rod near the vessel body, the sealing gasket being slidably connected to the sleeve, a spring being provided on the outer side of the sliding rod, and a fixing mechanism being provided on the mounting base.

[0007] Preferably, a limiting ring is fixedly connected inside the sleeve. The limiting ring contacts the sealing gasket, and the design of the limiting ring can limit the sealing gasket.

[0008] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the sleeve. Through the design of the spring, the sealing gasket can be driven to reset.

[0009] Preferably, the fixing mechanism includes a fixing block, the lower end of the mounting base is fixedly connected to the fixing block, the fixing block is in contact with the connecting pipe, the outer side of the fixing block is rotatably connected to a limit sleeve, the outer side of the connecting pipe is fixedly connected to a positioning plate, and the upper end of the positioning plate is fixedly connected to a positioning rod. Through the design of the fixing mechanism, the connecting pipe and the fixing pipe can remain stable after being inserted.

[0010] Preferably, the limiting sleeve contacts the mounting base, and the limiting sleeve is connected to the connecting pipe by a thread. The design of the limiting sleeve can limit the movement of the connecting pipe.

[0011] Preferably, a protrusion is fixedly connected to the outer side of the fixing block, and the protrusion is slidably connected to the limiting sleeve. Through the design of the protrusion, the limiting sleeve can be limited.

[0012] Preferably, the positioning plate contacts the limiting sleeve, and the positioning rod contacts the mounting base. Through the design of the positioning plate and the positioning rod, the connecting pipe can be limited.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model innovatively designs an automatic pressure relief structure that links the sleeve, sealing gasket, and fixed pipe. When the internal pressure of the vessel is too high, the pressure pushes the sealing gasket away from the opening of the fixed pipe, achieving rapid pressure relief. This solution precisely addresses the pain points of cumbersome and slow-response manual pressure relief operation in heating vessels. Through a pressure self-triggered mechanism, it ensures the timely release of high-pressure gas, significantly improving the safety and continuity of the calcium stearate processing process, and effectively avoiding risks such as equipment cracking and material leakage caused by untimely pressure relief.

[0014] 2. This utility model innovatively designs a leak-proof connection structure that coordinates a fixing block, a limiting sleeve, a positioning plate, and a positioning rod. The limiting sleeve axially limits the insertion of the connecting pipe and the fixing pipe, and the precise alignment of the positioning plate and positioning rod ensures a tight fit between the connecting pipe and the fixing pipe. This solution effectively solves the problems of easy loosening and poor sealing in traditional pipe connections, significantly improving the stability of fluid transmission in calcium stearate processing and avoiding material loss and safety hazards caused by leaks at the connection points.

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.

[0018] Please see Figure 1-5 A heating vessel for processing calcium stearate with a pressure relief structure includes a vessel body 1. A sleeve 2 is fixedly connected inside the vessel body 1. A mounting base 21 is fixedly connected to the lower end of the sleeve 2. A fixing pipe 22 is fixedly connected inside the mounting base 21. The fixing pipe 22 is fixedly connected to the sleeve 2. A connecting pipe 23 is inserted into the outside of the fixing pipe 22. A sliding rod 3 is slidably connected inside the sleeve 2. A sealing gasket 31 is fixedly connected to the side of the sliding rod 3 near the vessel body 1.

[0019] Please see Figure 2-5The sealing gasket 31 is slidably connected to the sleeve 2. The sleeve 2 is fixedly connected to the inside of the limiting ring 32, which is in contact with the sealing gasket 31. The limiting ring 32 can limit the sealing gasket 31 through its design. A spring 33 is provided on the outside of the slide rod 3. One end of the spring 33 is in contact with the slide rod 3, and the other end of the spring 33 is in contact with the sleeve 2. The spring 33 can drive the sealing gasket 31 to reset through its design. A fixing mechanism 4 is provided on the mounting base 21.

[0020] Please see Figure 2-5 The fixing mechanism 4 includes a fixing block 41, which is fixedly connected to the lower end of the mounting base 21. The fixing block 41 contacts the connecting pipe 23. A limiting sleeve 42 is rotatably connected to the outer side of the fixing block 41. The limiting sleeve 42 contacts the mounting base 21 and is threadedly connected to the connecting pipe 23. The limiting sleeve 42 is designed to limit the connection of the connecting pipe 23. A protrusion 43 is fixedly connected to the outer side of the fixing block 41. The protrusion 43 is slidably connected to the limiting sleeve 42. The protrusion 43 is designed to limit the connection of the limiting sleeve 42. A positioning plate 44 is fixedly connected to the outer side of the connecting pipe 23. A positioning rod 45 is fixedly connected to the upper end of the positioning plate 44. The positioning plate 44 contacts the limiting sleeve 42, and the positioning rod 45 contacts the mounting base 21. The positioning plate 44 and the positioning rod 45 are designed to limit the connection of the connecting pipe 23. The fixing mechanism 4 is designed to keep the connecting pipe 23 stable after it is inserted into the fixing pipe 22.

[0021] The specific implementation process of this utility model is as follows: In use, by inserting the connecting pipe 23 into the fixed pipe 22, the connecting pipe 23 drives the positioning rod 45 on the positioning plate 44 to slide into the mounting base 21. Then, the limiting sleeve 42 is rotated, so that the limiting sleeve 42 and the connecting pipe 23 undergo threaded movement, which can limit the connecting pipe 23. This can keep the connecting pipe 23 stable after it is inserted into the fixed pipe 22, and can prevent leakage at the connection between the connecting pipe 23 and the fixed pipe 22. When the internal pressure of the vessel body 1 is too high, the pressure is introduced into the sleeve 2, which causes the sealing gasket 31 to move within the sleeve 2. The sealing gasket 31 then moves the sliding rod 3, which in turn compresses the spring 33. This prevents the sealing gasket 31 from blocking the fixed pipe 22, allowing the air pressure to enter the fixed pipe 22 and then be discharged through the connecting pipe 23. This effectively relieves the pressure in the vessel body 1.
