Description

Technical Field

[0001] This invention relates to the field of CDM pipeline heating technology, specifically to an internal pipeline heating system. Background Technology

[0002] Liquid chemical delivery systems involve a range of technologies and equipment to ensure the safe, efficient, and reliable delivery of chemicals. Some liquid chemicals are prone to solidification and are not suitable for delivery using conventional technologies, thus requiring heated delivery.

[0003] Existing traditional heating methods typically involve heating and insulating outdoor pipes, which can only control the temperature of a section of the outdoor pipe to ensure its stability, while the temperature of other sections cannot be kept stable. Chemical outer casings have a relatively large outer diameter, requiring multiple heating elements to be applied simultaneously. This necessitates several heating control boxes, which are difficult to centrally control and consume relatively large amounts of electricity; the cabling required for the heating control boxes also increases. The construction of the heating section is also challenging, involving winding heating elements and running signal cables; the construction is relatively difficult and wastes manpower. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an internal pipeline heating system. This solution overcomes the limitations of existing traditional heating methods, which typically only heat and insulate outdoor pipelines. These methods can only control the temperature of a section of the outdoor pipeline to ensure its stability, while the temperature of other sections remains unstable. Furthermore, chemical outer casings have large outer diameters, requiring multiple heating elements simultaneously, necessitating several heating control boxes. Centralized control is difficult, and power consumption is relatively high. The required cabling for the heating control boxes also increases. Construction of the heating section is also challenging, involving the winding of heating elements and the laying of signal cables, resulting in significant construction difficulties and wasted labor.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An internal heating system for pipelines includes a CDM device, in which a CDM pipeline is installed. An installation plate is fixedly connected to the right side of the inner wall of the CDM device, and a clamping mechanism is provided inside the installation plate. A heating device is also installed inside the CDM device, with a fixed base fixedly connected to the middle right side of the heating device. The clamping mechanism clamps the fixed base. An air pump is installed on the top of the heating device, with its input end connected to an air inlet hopper and its output end extending into the interior of the heating device. An acceleration mechanism is installed inside the heating device to heat gas, and the acceleration mechanism accelerates the discharge of the heated gas. A filter screen is installed inside the air inlet hopper via the installation mechanism. Inspection doors are rotatably connected to symmetrical positions on the left and right sides of the front of the CDM device.

[0007] Preferably, the clamping mechanism includes a rotating component. The mounting plate consists of a top plate and a bottom frame. The rotating component is rotatably connected inside the bottom frame of the mounting plate. An external gear and an internal gear are fixedly connected to the outer and inner walls of the rotating component, respectively. A set of main gears and several sets of driven gears are also rotatably connected inside the bottom frame of the mounting plate. The external gears mesh with the main gears, and the several sets of driven gears mesh with the internal gears. Several sets of clamping components are slidably connected inside the bottom frame of the mounting plate. A rack that meshes with the driven gear is fixedly installed on the clamping component. A servo motor is installed at the bottom of the top plate of the mounting plate, and the output end of the servo motor is fixedly connected to the middle of the top of the main gear.

[0008] Preferably, the outer surface of the fixing seat is provided with a transition groove, which is adapted to the thickness of the clamping member.

[0009] Furthermore, in this solution, the output end of the servo motor drives the main gear to rotate, causing the rotating parts, external gear and internal gear to rotate as a whole, thereby driving several sets of driven gears to rotate synchronously, so that several sets of clamping parts can move towards the center position of the mounting plate, realizing the clamping of the transition groove of the fixed seat, realizing the quick installation of the heating device inside the CDM equipment, and also facilitating disassembly by the staff.

[0010] Preferably, the installation mechanism includes two sets of connecting plates, which are respectively fixedly connected to the inner sides of the air inlet hopper. A fixing ring is fixedly installed between the two sets of connecting plates. A rotating ring is provided inside the fixing ring. Three sets of arc-shaped grooves are opened through the top surface of the rotating ring, and three sets of through grooves are opened through the circumference of the fixing ring. A sliding component is slidably connected inside the arc-shaped groove.

[0011] Preferably, the upper and lower ends of the sliding member are fixedly connected to the locking block through a connecting member. The connecting member is slidably connected inside the through groove. A rotating shaft is fixedly connected to the middle of the bottom end of the rotating ring. A first bevel gear is fixedly installed at the other end of the rotating shaft. A sleeve is also fixedly connected inside the air inlet hopper. A rotating rod is rotatably connected inside the sleeve. A second bevel gear that meshes with the first bevel gear is fixedly installed at one end of the rotating rod. The other end of the rotating rod extends to the outside of the air inlet hopper and is fixedly connected to a rotating wheel.

[0012] Preferably, the top of the connecting plate is provided with a positioning groove, and both sides of the bottom of the filter screen are fixedly connected with positioning plates that are adapted to the positioning groove. The bottom of the filter screen is also fixedly connected with three sets of arc-shaped plates, and the inner side of the arc-shaped plates is provided with a slot adapted to the card block.

[0013] Furthermore, in this solution, when installing the filter screen, the positioning plate is placed inside the positioning groove. By rotating the rotating wheel, the rotating rod and the second bevel gear rotate synchronously, driving the first bevel gear and the rotating shaft to rotate synchronously. This causes the rotating ring to rotate, causing the sliding part to slide along the inside of the arc groove, and the connecting part to slide inside the through groove. This causes the locking block to move and extend into the locking slot to fix the filter screen. Conversely, the filter screen can be disassembled. By installing the filter screen, dust and other impurities are prevented from entering the interior of the heating device, thus meeting the needs of the staff.

[0014] Preferably, the acceleration mechanism includes a frame, and the heating device has frames fixedly connected to both sides of the interior. A threaded rod is rotatably connected inside the frame, and the threads at both ends of the outer surface of the threaded rod have opposite directions. A fixed rod is also fixedly installed inside the frame, and a first movable seat and a second movable seat are slidably connected to the outer surface of the fixed rod. The first movable seat and the second movable seat are respectively threaded to the two ends of the outer surface of the threaded rod.

[0015] Preferably, the acceleration mechanism further includes extrusion plates, and two sets of extrusion plates are provided and slidably connected to both sides inside the heating device. Guide rails are fixedly connected to the sides of the two sets of extrusion plates that are far apart from each other. A first sliding seat and a second sliding seat are slidably connected to both sides of the outer surface of the guide rails. Baffles are fixedly installed at both ends of the extrusion plates. The interiors of the first sliding seat and the second sliding seat are rotatably connected to both ends of one side of the telescopic member, and the other ends of the telescopic member are rotatably connected to the first movable seat and the second movable seat.

[0016] Preferably, a stepper motor is fixedly installed on the outside of the frame, the output end of the stepper motor extends into the inside of the frame and is fixedly connected to one end of the threaded rod, a limiting groove is also opened inside the heating device, a limiting member adapted to the limiting groove is fixedly connected to the extrusion plate, and the limiting member is slidably connected inside the limiting groove.

[0017] Preferably, the air outlet of the heating device is connected to several sets of nozzles, which are evenly distributed at equal intervals and have a structure that is wide at both ends and narrow in the middle.

[0018] Furthermore, in this solution, after the hot gas is heated by the heating device, the nozzle is intelligently controlled. During the heating process, the nozzle is in a closed state, and when the hot gas is released, the nozzle automatically opens.

[0019] Compared with the prior art, the present invention provides an internal heating system for pipelines, which has the following beneficial effects:

[0020] 1. This invention drives the main gear to rotate through the output end of the servo motor, causing the rotating parts, external gear and internal gear to rotate as a whole, thereby driving several sets of driven gears to rotate synchronously, so that several sets of clamping parts can move towards the center position of the mounting plate, realizing the clamping of the transition groove of the fixed seat, realizing the rapid installation of the heating device inside the CDM equipment, occupying a small space and being easy to control.

[0021] 2. Secondly, by placing the positioning plate inside the positioning groove, the rotating wheel is rotated so that the rotating rod and the second bevel gear rotate synchronously, which drives the first bevel gear and the rotating shaft to rotate synchronously. In turn, the rotating ring rotates, causing the sliding member to slide along the inside of the arc groove, and the connecting member to slide inside the through groove, which drives the locking block to move and extend into the locking groove to fix the filter screen, thus preventing dust and other impurities from entering the interior of the heating device.

[0022] 3. The present invention also drives the threaded rod to rotate through the output end of the stepper motor, so that the first movable seat and the second movable seat move closer to each other, and the first sliding seat and the second sliding seat also move closer to each other. The telescopic component is in an extended state, which causes the two sets of extrusion plates to move closer to each other, thereby extruding the hot gas and accelerating the release speed of the hot gas. It is worth noting that since the nozzle has a structure that is wide at both ends and narrow in the middle, the gas that has been accelerated for the first time will be accelerated and released for the second time through the "narrow" part, so that the hot gas can quickly fill the interior of the CDM equipment, making the entire CDM pipeline heat evenly and preventing the liquid inside the CDM pipeline from solidifying.

[0045] Those skilled in the art will understand that the main gear 206 is driven to rotate by the output end of the servo motor 208, causing the rotating part 201, the external gear 203 and the internal gear 202 to rotate as a whole, thereby driving several sets of driven gears 204 to rotate synchronously, so that several sets of clamping parts 205 can move toward the center position of the mounting plate 103, thereby clamping the transition groove 112 of the fixed seat 104, realizing the rapid installation of the heating device 105 inside the CDM equipment 1, and also facilitating disassembly by the staff.

[0046] Example 3

[0047] Please refer to Figure 8 and Figure 9 As shown, the installation mechanism 3 includes two sets of connecting plates 301, which are fixedly connected to the inside sides of the air inlet hopper 107 respectively. A fixing ring 303 is fixedly installed between the two sets of connecting plates 301. A rotating ring 304 is provided inside the fixing ring 303. Three sets of arc-shaped grooves 305 are opened through the top surface of the rotating ring 304, and three sets of through grooves 309 are opened through the circumference of the fixing ring 303. A sliding member 306 is slidably connected inside the arc-shaped grooves 305.

[0048] Please refer to Figure 9 and Figure 11 As shown, the upper and lower ends of the sliding member 306 are fixedly connected to the locking block 308 through the connecting member 307. The connecting member 307 is slidably connected inside the through groove 309. The bottom center of the rotating ring 304 is fixedly connected to the rotating shaft 310. The other end of the rotating shaft 310 is fixedly installed with the first bevel gear 311. The inside of the air inlet hopper 107 is also fixedly connected to the sleeve 312. The inside of the sleeve 312 is rotatably connected to the rotating rod 313. One end of the rotating rod 313 is fixedly installed with the second bevel gear 314 that meshes with the first bevel gear 311. The other end of the rotating rod 313 extends to the outside of the air inlet hopper 107 and is fixedly connected to the rotating wheel 315.

[0049] Please refer to Figure 10 As shown, the top of the connecting plate 301 is provided with a positioning groove 302, and the bottom two sides of the filter screen 108 are fixedly connected with positioning plates 109 that are compatible with the positioning groove 302. The bottom of the filter screen 108 is also fixedly connected with three sets of arc plates 110, and the inner side of the arc plate 110 is provided with a slot 111 that is compatible with the card block 308.

[0050] Those skilled in the art will understand that when installing the filter screen 108, by placing the positioning plate 102 inside the positioning groove 302, and rotating the rotating wheel 315, the rotating rod 313 and the second bevel gear 314 rotate synchronously, driving the first bevel gear 311 and the rotating shaft 310 to rotate synchronously, thereby rotating the rotating ring 304, causing the sliding member 306 to slide along the inside of the arc groove 305, and causing the connecting member 307 to slide inside the through groove 309, driving the locking block 308 to move and extend into the locking groove 104 to fix the filter screen 108. Conversely, the filter screen 108 can be disassembled. Furthermore, by providing the filter screen 101, dust and other impurities are prevented from entering the interior of the heating device 105, thus meeting the needs of the staff.

[0051] Example 4

[0052] Please refer to Figure 6 As shown, the acceleration mechanism 4 includes a frame 401. The heating device 105 is fixedly connected to both sides of the frame 401. A threaded rod 402 is rotatably connected inside the frame 401. The threads at both ends of the outer surface of the threaded rod 402 have opposite directions. A fixed rod is also fixedly installed inside the frame 401. A first movable seat 403 and a second movable seat 404 are slidably connected to the outer surface of the fixed rod. The first movable seat 403 and the second movable seat 404 are respectively threaded to the two ends of the outer surface of the threaded rod 402.

[0053] Please refer to Figure 6 As shown, the acceleration mechanism 4 also includes a pressing plate 405. Two sets of pressing plates 405 are provided and are slidably connected to both sides inside the heating device 105. The two sets of pressing plates 405 are fixedly connected to guide rails 406 on the side away from each other. The outer surfaces of the guide rails 406 are slidably connected to the first sliding seat 408 and the second sliding seat 409 respectively. The two ends of the pressing plate 405 are fixedly installed with baffles 407. The interiors of the first sliding seat 408 and the second sliding seat 409 are rotatably connected to the two ends of one side of the telescopic member 410, and the two ends of the other side of the telescopic member 410 are rotatably connected to the first movable seat 403 and the second movable seat 404 respectively.

[0054] Please refer to Figure 6 As shown, a stepper motor 412 is fixedly installed on the outside of the frame 401. The output end of the stepper motor 412 extends into the inside of the frame 401 and is fixedly connected to one end of the threaded rod 402. A limiting groove 411 is also opened inside the heating device 105. A limiting member that matches the limiting groove 411 is fixedly connected on the extrusion plate 405, and the limiting member is slidably connected inside the limiting groove 411.

[0055] Please refer to Figure 7As shown, the outlet of the heating device 105 is connected to several sets of nozzles 413. The several sets of nozzles 413 are evenly distributed at equal intervals, and the nozzles 413 have a structure that is wide at both ends and narrow in the middle.

[0056] As those skilled in the art will understand, after the hot gas is heated by the heating device 105, the nozzle 413 is intelligently controlled. During the heating process, the nozzle 413 is in a closed state, and when releasing the hot gas, the nozzle 413 automatically opens. First, the output end of the stepper motor 412 drives the threaded rod 402 to rotate, causing the first movable seat 403 and the second movable seat 404 to move closer to each other, and the first sliding seat 408 and the second sliding seat 409 to move closer to each other as well. The telescopic member 410 is in an extended state, which causes the two sets of extrusion plates 405 to move closer to each other, thereby extruding the hot gas and accelerating the release speed of the hot gas. It is worth noting that because the nozzle 413 has a structure that is wide at both ends and narrow in the middle, the gas that has been accelerated for the first time will be accelerated and released a second time through the "narrow" part, so that the hot gas quickly fills the interior of the CDM device 1, making the entire CDM pipeline 101 heated evenly, preventing the liquid inside the CDM pipeline 101 from solidifying, and meeting the needs of the staff.

[0057] The working principle and usage process of this device are as follows: During use, the output of the servo motor 208 drives the main gear 206 to rotate, causing the rotating component 201, external gear 203, and internal gear 202 to rotate as a whole. This, in turn, drives several sets of driven gears 204 to rotate synchronously, allowing several sets of clamping components 205 to move towards the center of the mounting plate 103, thus clamping the transition groove 112 of the fixed seat 104. This enables the heating device 105 to be quickly installed inside the CDM equipment 1. Next, the air pump 106 is installed, and then the positioning plate 102 is placed in the positioning groove 302. Internally, by rotating the rotating wheel 315, the rotating rod 313 and the second bevel gear 314 rotate synchronously, driving the first bevel gear 311 and the rotating shaft 310 to rotate synchronously. This causes the rotating ring 304 to rotate, causing the sliding member 306 to slide along the inside of the arc-shaped groove 305, and the connecting member 307 to slide inside the through groove 309. This drives the locking block 308 to move and extend into the locking slot 104, fixing the filter screen 108. The filter screen 101 prevents dust and other impurities from entering the heating device 105, meeting the needs of the operators. The air pump 106... Under the action of the nozzle, external gas enters the heating device 105 for heating. The nozzle 413 is in a closed state. After heating is completed, the nozzle 413 automatically opens, driving the threaded rod 402 to rotate through the output end of the stepper motor 412. This causes the first movable seat 403 and the second movable seat 404 to move closer to each other, and the first sliding seat 408 and the second sliding seat 409 to move closer to each other as well. The telescopic member 410 is in an extended state, which causes the two sets of extrusion plates 405 to move closer to each other, thereby compressing the hot gas and accelerating the release of the hot gas. It is worth noting that because the nozzle... 413 has a structure that is wide at both ends and narrow in the middle. The gas that is accelerated for the first time will be accelerated and released a second time through the "narrow" part, so that the hot gas can quickly fill the interior of the CDM device 1, making the entire CDM pipeline 101 heated evenly. This can prevent the liquid inside the CDM pipeline 101 from solidifying, which meets the needs of the staff. Moreover, this invention changes the traditional heating method, thereby eliminating the need for the installation and construction of heating belts and heating control boxes. It has practical significance and good application prospects. Furthermore, the heating device 105 is integrated inside the CDM device 1, which occupies less space and is easy to control.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
