Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and more specifically, to an automated conveying device for the production of chlorinated paraffin. Background Technology
[0002] Chlorinated paraffin is an organic compound, a chlorinated derivative of paraffin hydrocarbons. It possesses advantages such as low volatility, flame retardancy, good electrical insulation, and low cost, and can be used as a flame retardant and auxiliary plasticizer for polyvinyl chloride (PVC). It is widely used in the production of cable materials, flooring materials, hoses, artificial leather, rubber products, and as an additive in polyurethane waterproof coatings, polyurethane running tracks, lubricants, and more.
[0003] In the production of chlorinated paraffin, the conveying pipeline is a crucial link in ensuring continuous and efficient production. However, chlorinated paraffin has the characteristic of increasing viscosity and easy solidification as the temperature decreases. When the ambient temperature drops, especially in winter or some low-temperature production environments, the temperature inside the conveying pipeline also decreases, and chlorinated paraffin easily solidifies on the inner wall of the pipeline. This solidification of chlorinated paraffin on the inner wall of the conveying pipeline can cause a series of serious problems. On the one hand, the solidified layer will gradually thicken, resulting in a smaller inner diameter of the pipeline and a significant increase in conveying resistance. When the solidification is too thick, the corresponding conveying pressure needs to be increased to maintain the original conveying capacity, which not only increases energy consumption but also seriously affects the service life of the conveying equipment. On the other hand, the solidified chlorinated paraffin may detach locally and flow with the material, causing blockages in downstream equipment, such as filters and reactor inlets, thus leading to production interruptions.
[0004] Therefore, there is an urgent need for an automated conveying device for chlorinated paraffin production to improve the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to provide an automated conveying device for the production of chlorinated paraffin. It adopts a combination of steam heating and electric heating, which can control the temperature fluctuation of the pipeline within ±2℃, providing a reliable temperature guarantee for the stable conveying of chlorinated paraffin. Since the electric heating and steam heating effectively prevent the condensation of chlorinated paraffin on the inner wall of the pipeline, it solves the problem mentioned in the background art that chlorinated paraffin in the conveying pipeline is prone to condensation on the inner wall at low temperatures.
[0006] To achieve the above objectives, this utility model provides an automated conveying device for chlorinated paraffin production, including a conveying assembly, a conveying pipe, a heating assembly fixedly connected to the surface of the conveying pipe, the heating assembly including an electric heating tape wrapped around the surface of the conveying pipe, a temperature sensor fixedly connected to the surface of the conveying pipe, the electric heating tape activating to heat the conveying pipe when the temperature sensor detects a temperature drop, and a steam heating pipe for raising the temperature of the conveying pipe is provided on one side of the conveying pipe.
[0007] As a further improvement to this technical solution, the conveying pipeline is made of alloy steel.
[0008] As a further improvement to this technical solution, the surface of the conveying pipe is fitted with a clamp for fixing the conveying pipe, and a bracket is fixedly connected to the lower surface of the clamp.
[0009] As a further improvement to this technical solution, the lower end of the bracket is provided with a fixing hole, and the bracket is used to suspend the conveying pipeline to reduce heat loss.
[0010] As a further improvement to this technical solution, the conveying pipe is fitted with a limit clamp, and the limit clamp is used to connect the conveying pipe and the steam tracing pipe.
[0011] As a further improvement to this technical solution, the conveying pipe and the steam tracing pipe are spaced 5-10 cm apart.
[0012] As a further improvement to this technical solution, the electric heating tape is fixed to the outer wall of the conveying pipeline at intervals of 5-15 cm.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This automated conveying system for chlorinated paraffin production incorporates an electric heating tape, which automatically adjusts its output power based on pipeline temperature. When the pipeline temperature approaches the condensation temperature of chlorinated paraffin, the electric heating tape quickly activates, converting electrical energy into heat to heat the pipeline. Meanwhile, a steam heating tape releases heat through the flow of steam within the pipeline, working in synergy with the electric heating tape to further ensure uniform and stable pipeline temperature within a suitable range. In cold winter regions, the combination of steam and electric heating tapes can control pipeline temperature fluctuations within ±2℃, providing reliable temperature protection for the stable transport of chlorinated paraffin. Because the electric and steam heating tapes effectively prevent the condensation of chlorinated paraffin on the pipeline inner wall, the pipeline inner diameter remains constant, and the transport resistance is stable. This allows the conveying equipment to operate continuously and efficiently, eliminating the need for frequent shutdowns for maintenance due to pipeline blockage or increased resistance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figures 1-3 As shown, this embodiment provides an automated conveying device for chlorinated paraffin production, including a conveying component 1. The conveying component 1 includes a conveying pipe 100. A heating component 2 is fixedly connected to the surface of the conveying pipe 100. The heating component 2 includes an electric heating tape 202, which is wrapped around the surface of the conveying pipe 100. A temperature sensor 103 is fixedly connected to the surface of the conveying pipe 100. When the temperature sensor 103 detects a temperature drop, it turns on the electric heating tape 202 to heat the conveying pipe 100. A steam heating pipe 200 for raising the temperature of the conveying pipe 100 is provided on one side of the conveying pipe 100.
[0023] The working principle is as follows: First, the conveying pipe 100 is used to transport chlorinated paraffin. When the device is running, the temperature sensor 103 installed on the surface of the conveying pipe 100 monitors the pipe temperature in real time. Since chlorinated paraffin easily condenses on the inner wall of the pipe when the temperature drops, once the temperature sensor 103 detects that the temperature has dropped to near the condensation temperature range of chlorinated paraffin, it will immediately send a signal to activate the heating component 2 that works in conjunction with it. The electric heating tape 202 in the heating component 2 is tightly wrapped around the surface of the conveying pipe 100. After receiving the activation signal, it quickly converts electrical energy into heat energy to heat the conveying pipe 100. At the same time, the steam heating pipe 200 located on one side of the conveying pipe 100 also begins to function. Steam flows in the pipe, continuously releasing heat. Together with the electric heating tape 202, the two layers work together to raise the temperature of the conveying pipe 100, ensuring that the temperature inside the pipe is always maintained within a suitable range that can effectively prevent the condensation of chlorinated paraffin, ensuring the fluidity of chlorinated paraffin during the transportation process, and achieving stable and efficient automated transportation.
[0024] To reduce heat loss by suspending the pipeline, in this embodiment, the conveying pipeline 100 is made of alloy steel. A clamp 102 is fitted onto the surface of the conveying pipeline 100 for fixing it. A bracket 101 is fixedly connected to the lower surface of the clamp 102, and the lower end of the bracket 101 has a fixing hole. The alloy steel material used for the conveying pipeline 100 provides good strength and thermal insulation performance, offering a fundamental guarantee for reducing heat loss. The clamp 102 fitted onto the pipeline surface plays a crucial connecting role, tightly wrapping around the conveying pipeline 100 to ensure a stable connection. The bracket 101 fixedly connected to the lower surface of the clamp 102 supports the conveying pipeline 100, allowing it to be suspended. The fixing hole at the lower end of the bracket 101 allows for secure fixing to the ground, wall, or other supporting structures using bolts or other connectors, preventing the bracket 101 from shaking or shifting. By using this overhead method, the contact area between the conveying pipeline 100 and the surrounding environment is reduced, and the conduction of heat to low-temperature areas such as the ground is greatly reduced, which effectively reduces heat loss, helps maintain the temperature of chlorinated paraffin inside the pipeline, ensures its fluidity, and improves conveying efficiency.
[0025] To secure the steam tracing pipe 200, in this embodiment, a limiting clamp 201 is fitted onto the conveying pipe 100. The limiting clamp 201 engages both the conveying pipe 100 and the steam tracing pipe 200, simultaneously engaging both. When installing the limiting clamp 201, it is accurately fitted onto the conveying pipe 100, and then the steam tracing pipe 200 is placed in the corresponding slot or engagement part of the limiting clamp 201. Through the fastening action of the limiting clamp 201, the steam tracing pipe 200 and the conveying pipe 100 maintain a relatively fixed positional relationship.
[0026] To ensure the heating device is positioned optimally and thus reduce energy consumption, in this embodiment, the conveying pipe 100 and the steam tracing pipe 200 are spaced 5-10 cm apart. The electric heating tape 202 is fixed to the outer wall of the conveying pipe 100 every 5-15 cm. This 5-10 cm interval ensures that the heat released from the steam tracing pipe 200 is efficiently transferred to the conveying pipe 100, while avoiding uneven heat distribution or safety hazards caused by excessive proximity. Within this interval, heat can be conducted at a suitable rate, ensuring uniform heating of the conveying pipe 100. Similarly, the electric heating tape 202, fixed to the outer wall of the conveying pipe 100 every 5-15 cm, also aims to achieve uniform and efficient heating.
[0027] In this embodiment, an automated conveying device for chlorinated paraffin production is used. Firstly, the conveying pipe 100 of the conveying component 1 is made of alloy steel, whose excellent strength and heat insulation provide a foundation for the entire conveying process. The surface-mounted clamps 102 and the connected brackets 101 are securely connected to the supporting structure through the fixing holes at the lower end of the brackets 101. This suspends the conveying pipe 100, effectively reducing heat conduction to low-temperature areas such as the ground and minimizing heat loss. Simultaneously, the limiting clamps 201 on the pipe securely connect the steam tracing pipe 200 to the conveying pipe 100, ensuring their relative position is stable and maintaining the stability of heat transfer.
[0028] Temperature sensors 103, installed on the surface of the conveying pipe 100, constantly monitor the temperature. Upon detecting a temperature drop, a response mechanism is immediately triggered. Electric heating tape 202, tightly wound around the outer wall of the pipe and fixed at 5-15 cm intervals, quickly activates, converting electrical energy into heat. Simultaneously, steam heating pipes 200, spaced 5-10 cm apart from the conveying pipe 100, release heat through internal steam flow. Working together, these two components raise the temperature of the conveying pipe 100 from both internal and external perspectives, precisely controlling temperature fluctuations within ±2℃. This effectively prevents chlorinated paraffin from condensing on the inner wall of the pipe, providing a robust and reliable temperature guarantee for the stable, efficient, and automated conveying of chlorinated paraffin.
