Description

Technical Field

[0001] This utility model relates to the technical field of pipeline antifreeze equipment, and in particular to an antifreeze protection device for dimethyl carbonate conveying pipelines. Background Technology

[0002] The dimethyl carbonate (DMC) pipeline antifreeze protection device is a protective system specifically designed to prevent blockages or pipeline ruptures caused by the solidification and freezing of the medium in low-temperature environments. It uses a temperature monitoring module to sense the pipeline temperature in real time. When the temperature falls below a set threshold, it automatically activates the heating components to maintain the medium flow temperature, and works in conjunction with the insulation layer to reduce heat loss. It also features over-temperature protection and fault alarm functions, is adaptable to different pipe diameters, and ensures the safe and stable transportation of DMC under low-temperature conditions. It is widely used in material handling systems in the chemical and pharmaceutical industries.

[0003] However, most existing antifreeze equipment is an integral structure. When the antifreeze equipment is damaged or malfunctions and needs to be replaced urgently, it can only be completely disassembled and replaced. This greatly affects the replacement efficiency and increases the replacement cost. At the same time, existing pipes and antifreeze equipment are easily corroded by external moisture, humidity, corrosive gases, and trace amounts of corrosive media volatilized from dimethyl carbonate, causing parts to rust and age faster, resulting in a shorter service life of the equipment, increased replacement costs and equipment downtime for maintenance.

[0004] Therefore, we propose an antifreeze protection device for dimethyl carbonate transport pipelines to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dimethyl carbonate (DMC) transport pipeline antifreeze protection device includes a mounting base. Two guide grooves are formed on one side of the mounting base. A linkage column is slidably installed on the inner side of each of the two guide grooves. A displacement base is fixedly installed at one end of each of the two linkage columns. A displacement sleeve assembly is fixedly installed on one side of each of the two displacement sleeve assemblies. An installation sleeve assembly is provided on one side of each of the two displacement sleeve assemblies.

[0007] Specifically, silicone pads are fixedly installed on the inner sides of the two displacement sleeve assemblies and the two mounting sleeve assemblies to enhance the tightness of the connection between the two displacement sleeve assemblies and the pipeline.

[0008] Specifically, the interiors of the two displacement sleeve assemblies and the two mounting sleeve assemblies are each provided with multiple heating grooves, and electric heating rods are fixedly installed on the inner side of each heating groove to facilitate heating and freezing of the pipeline.

[0009] Specifically, the antifreeze sleeve consists of two displacement sleeve assemblies and two mounting sleeve assemblies. The outer side of the antifreeze sleeve is covered with heat shrink film, which can not only prevent dust but also enhance the antifreeze effect of the equipment.

[0010] Specifically, the mounting base has an adjustment chamber inside, and two guide grooves are connected to the same adjustment chamber. A turntable is rotatably installed on one inner wall of the adjustment chamber, and a worm gear is fixedly sleeved on the outer side of the turntable. Two linkage ports are opened on one side of the turntable, and corresponding linkage columns are slidably installed on the inner side of the two linkage ports respectively. The rotation of the turntable can drive the two linkage columns to move.

[0011] Specifically, the mounting base has a drive groove inside, which is connected to the adjustment chamber. A worm gear is rotatably mounted on one inner wall of the drive groove, and the worm gear meshes with a worm wheel. A servo motor is fixedly mounted on the top inner wall of the drive groove, and the output shaft of the servo motor is fixedly connected to the worm gear. The servo motor can drive the worm gear to rotate.

[0012] Specifically, a displacement metal block is fixedly installed on one side of each of the two displacement sleeve assemblies, and two nuts are fixedly inserted through one side of each of the two displacement metal blocks.

[0013] Specifically, a mounting metal block is fixedly installed on one side of each of the two mounting sleeve assemblies. Two mounting holes are opened on one side of each of the two mounting metal blocks. Threaded rods are slidably installed on the inner side of each of the four mounting holes. The four threaded rods are threadedly connected to the corresponding nuts, which facilitates the connection of the displacement metal block with the corresponding mounting metal block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting two displacement sleeve assemblies and two installation sleeve assemblies, they can be combined to form an antifreeze sleeve that is fitted on the outside of the pipe for heat preservation and antifreeze. When the antifreeze sleeve is damaged, it can be replaced at the damaged part without the need for overall disassembly and replacement, which improves the replacement efficiency and reduces maintenance costs. In addition, the heat shrink film can block external moisture, humidity, corrosive gases, and trace amounts of corrosive media volatilized from dimethyl carbonate, preventing them from corroding equipment parts, causing parts to rust and age faster, and extending the service life of the equipment.

A linkage column 8 is slidably installed on the inner side of each of the two guide grooves. A displacement base 7 is fixedly installed at one end of each of the two linkage columns 8. A displacement sleeve assembly 3 is fixedly installed on one side of each of the two displacement sleeve assemblies 7. An mounting sleeve assembly 4 is provided on one side of each of the two displacement sleeve assemblies 3.

[0022] In this embodiment, silicone pads 5 are fixedly installed on the inner sides of the two displacement sleeve assemblies 3 and the two mounting sleeve assemblies 4 to enhance the tightness of the connection between the two displacement sleeve assemblies 3 and the two mounting sleeve assemblies 4 and the pipeline.

[0023] In this embodiment, multiple heating grooves are provided inside the two displacement sleeve assemblies 3 and the two mounting sleeve assemblies 4, and electric heating rods 6 are fixedly installed on the inner side of the multiple heating grooves to facilitate heating and antifreeze of the pipeline.

[0024] In this embodiment, two displacement sleeve assemblies 3 and two mounting sleeve assemblies 4 form an antifreeze sleeve. The outer side of the antifreeze sleeve is covered with a heat shrink film 2, which can not only prevent dust but also enhance the antifreeze effect of the equipment.

[0025] In this embodiment, the mounting base 1 has an adjustment chamber inside, and two guide grooves are connected to the same adjustment chamber. A turntable 9 is rotatably installed on one inner wall of the adjustment chamber. A worm gear 11 is fixedly sleeved on the outer side of the turntable 9. Two linkage ports 10 are opened on one side of the turntable 9. Corresponding linkage columns 8 are slidably installed on the inner side of the two linkage ports 10 respectively. The rotation of the turntable 9 can drive the two linkage columns 8 to move.

[0026] In this embodiment, a drive groove is provided inside the mounting base 1. The drive groove is connected to the adjustment chamber. A worm gear 12 is rotatably mounted on one inner wall of the drive groove. The worm gear 12 meshes with the worm wheel 11. A servo motor 13 is fixedly mounted on the top inner wall of the drive groove. The output shaft of the servo motor 13 is fixedly connected to the worm gear 12. The servo motor 13 can drive the worm gear 12 to rotate.

[0027] In this embodiment, a displacement metal block 14 is fixedly installed on one side of each of the two displacement sleeve assemblies 3, and two nuts 15 are fixedly inserted through one side of each of the two displacement metal blocks 14.

[0028] In this embodiment, a mounting metal block 16 is fixedly installed on one side of each of the two mounting sleeve assemblies 4. Two mounting holes are opened on one side of each of the two mounting metal blocks 16. Threaded rods 17 are slidably installed on the inner side of each of the four mounting holes. The four threaded rods 17 are threadedly connected to the corresponding nuts 15, which facilitates the connection of the displacement metal block 14 to the corresponding mounting metal block 16.

[0029] Working Principle: During use, after the pipeline is installed, the mounting base 1 is fixed to the wall near the pipeline using expansion bolts. Then, the servo motor 13 is started, driving the worm gear 12 to rotate. The worm gear 12 rotates, driving the worm wheel 11 to rotate, which in turn drives the turntable 9 to rotate. Two linkage ports 10 are provided on one side of the turntable 9, and linkage columns 8 are slidably installed inside each port 10. One end of each linkage column 8 is fixedly connected to a corresponding displacement base 7. Two guide grooves are provided on one side of the mounting base 1, and the two linkage columns 8 are slidably installed inside their respective guide grooves. Therefore, when the turntable 9 rotates, it moves the two linkage ports 10, causing the corresponding linkage columns 8 to move along their respective guide grooves. The two displacement bases 7 move, causing their respective displacement sleeve assemblies 3 to move closer together. The pipe is clamped close to each other, and then the workers assemble the two installation sleeve assemblies 4 with the corresponding displacement sleeve assemblies 3 respectively, so that the two mounting holes on one side of the two displacement sleeve assemblies 3 are aligned with the corresponding nuts 15. Then, the threaded rod 17 is passed through the mounting hole and threadedly connected to the nut 15 to complete the installation and fixation of the two installation sleeve assemblies 4. At this time, the two displacement sleeve assemblies 3 and the two installation sleeve assemblies 4 form an antifreeze sleeve to insulate the pipe. After the workers put the heat shrink film 2 on the outside of the antifreeze sleeve, they use a hot air blower to shrink it. The heat shrink film 2 wraps the antifreeze sleeve, which can prevent dust, impurities, oil stains, etc. from entering the equipment, avoid the bracket adjustment jamming or malfunction caused by the accumulation of foreign objects, and effectively isolate moisture, humidity, corrosive gases, and trace amounts of corrosive media that may volatilize during the transportation of dimethyl carbonate from the external environment, thus extending the service life of the equipment.

[0030] The technological advancements of this invention compared to existing technologies are as follows: it can be assembled into an antifreeze sleeve and fitted onto the outside of the pipe for insulation and antifreeze protection. When the antifreeze sleeve is damaged, it can be replaced only at the damaged part, eliminating the need for complete disassembly and replacement. This improves replacement efficiency and reduces maintenance costs. Furthermore, the heat-shrinkable film 2 can block external moisture, humidity, corrosive gases, and trace amounts of corrosive media volatilized from dimethyl carbonate, preventing them from corroding equipment components, causing rust and accelerated aging, and extending the service life of the equipment.
