Description

Technical Field

[0001] The present invention relates to the technical field of incineration system maintenance equipment, and more specifically, to a pipeline coking treatment device and a use method thereof. Background Art

[0002] Incineration is a common technical means of hazardous waste treatment. A large amount of flue gas will be generated during the incineration process of hazardous waste. These flue gases will be discharged through the smoke exhaust pipe (output to the flue gas environmental protection treatment equipment for further treatment). Coking is the most common problem of the smoke exhaust pipe. After the hazardous waste incineration system has been running for a long time, a thick layer of coke will form inside the smoke exhaust pipe. After the smoke exhaust pipe is coked, it will seriously affect the normal operation of the hazardous waste incineration system (mainly causing poor smoke discharge). Therefore, it is necessary to monitor the coking situation in the pipe at all times. When the coking is serious, the pipe needs to be disassembled for decoking. The common pipeline decoking method is chemical decoking, which is to configure a chemical liquid for decoking and spray it into the inside of the pipe to perform decoking operations. However, this decoking method has the problems of high cost and difficult waste liquid treatment, and it is easy to cause personal injury risks to workers (risk of contact with chemical solutions).

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 6The pipeline coking treatment device shown is used for the coking layer removal operation of the straight pipeline, and includes a pipe seat 1, a first machine seat 2, a second machine seat 3 and a cutter head 5. A plurality of pipe seats 1 are arranged along a straight line, and the straight pipeline is placed transversely on the pipe seat 1. During the decoking operation, the straight pipeline needs to remain fixed, so the straight pipeline is fixedly connected to the pipe seat 1. The first machine seat 2 and the second machine seat 3 are installed respectively corresponding to the two end pipe openings of the straight pipeline. The first machine seat 2 and the second machine seat 3 are installed at the same height. A first turntable 21 is rotatably installed on the first machine seat 2, and a second turntable 31 is rotatably installed on the second machine seat 3. A plurality of sliding rods 4 are fixedly installed between the first turntable 21 and the second turntable 31, and the first turntable 21 and the second turntable 31 are fixedly connected by the sliding rod 4. The first turntable 21 and the second turntable 31 play a supporting role of the sliding rod 4, and the first turntable 21 and the second turntable 31 can rotate synchronously through the sliding rod 4, as shown in FIG. Figure 3 As shown, the number of slide bars 4 installed is not less than 6, and all slide bars 4 are evenly distributed on the same circumference line, so as to ensure the smooth progress of the rotation transmission. Figure 2 As shown, all the slide bars 4 are installed in the inner hole of the straight pipe, and the cutter disc 5 is matched and inserted into all the slide bars 4. When the first turntable 21 and the second turntable 31 rotate, the slide bar 4 can drive the cutter disc 5 to rotate. The slide bar 4 passes through the inner hole of the straight pipe for installation. The slide bar 4 is parallel to the central axis of the inner hole of the straight pipe. The cutter disc 5 just matches the inner hole size of the straight pipe. The high-speed rotation of the cutter disc 5 can remove the coking layer on the inner hole wall of the straight pipe. The first machine base 2 is equipped with a rotation drive mechanism 6, which is transmission connected to the first turntable 21. The rotation drive mechanism 6 can drive the first turntable 21 to rotate, and then drive the second turntable 31 to rotate synchronously through the slide bar 4. Since the cutter disc 5 is inserted into the slide bar 4, the cutter disc 5 can also rotate together. The first machine base 2 and the second machine base 3 are equipped with a transverse driving mechanism 7, which is transmission connected to the cutter disc 5. The slide bar 4 can drive the cutter disc 5 to rotate, but does not limit the cutter disc 5 moves along the length direction of the slide bar 4, the length direction of the slide bar 4 is the length direction of the inner hole of the straight pipe. When the cutter head 5 rotates, the cutter head 5 can be driven to move along the length direction of the inner hole of the straight pipe through the transverse driving mechanism 7. The cutter head 5 can completely move through the inner hole of the straight pipe to completely remove the coking layer on the inner hole wall of the straight pipe. The length of the slide bar 4 is designed to be slightly longer than the length of the pipe to ensure that the stroke of the cutter head 5 can cover the total length of the pipe. The present invention adopts a high-speed cutting method of the tool to complete the decoking operation inside the pipe. This is a physical decoking method. Compared with the existing chemical decoking method, no chemical agents are required, the cost is greatly reduced, there is no waste liquid to be processed after decoking, the burden of later processing is greatly reduced, workers do not need to contact chemical agents, and the safety of decoking operation is also greatly improved. Since the cutter head 5 of the present invention can only achieve linear movement, the present invention is only suitable for decoking operations in straight pipes.

[0019] like Figure 6 As shown, a V-shaped notch 11 is provided on the upper end surface of the tube seat 1, and the V-shaped notch 11 can stabilize the tube body of the pipeline. The tube seat 1 of the present invention adopts an electromagnetic seat body, and the tube seat 1 can generate magnetic force when it is energized. This design fully considers the material properties of the existing pipeline. After the tube seat 1 generates magnetic force, the pipeline can be firmly adsorbed on the tube seat 1 to ensure that there is no displacement of the pipeline during the decoking operation. Of course, the tube seat 1 can also use traditional fixing methods such as bundling to fix the pipeline.

[0020] like Figure 3 As shown, a plurality of scrapers 51 are fixedly installed on the outer edge of the cutter disc 5, and the plurality of scrapers 51 are evenly distributed along the outer edge contour line of the cutter disc 5. When the cutter disc 5 rotates, the scrapers 51 move in height. As the cutter disc 5 moves laterally, the cutter disc 5 enters the pipeline, and the scrapers 51 contact the coking layer and effectively remove it.

[0021] like Figure 2 As shown, the rotation drive mechanism 6 includes a first motor 61 and a driving gear 62. The first motor 61 is fixedly mounted on the first machine base 2. The driving gear 62 is connected to the output end of the first motor 61. A circle of transmission gear ring 63 is connected to the outer edge of the first turntable 21. The driving gear 62 is meshed with the transmission gear ring 63. The first motor 61 drives the driving gear 62 to rotate, and then drives the first turntable 21 to rotate through the meshing relationship between the driving gear 62 and the transmission gear ring 63. When the first turntable 21 rotates, the slide bar 4 moves synchronously to drive the second turntable 31 to rotate synchronously. The knife disc 5 on the slide bar 4 can also be driven to rotate to form a high-speed rotation effect of the scraper 51.

[0022] like Figure 2 As shown, a first boss 22 is provided on the first machine base 2, and the first turntable 21 is rotatably connected to the outer wall of the first boss 22. A second boss 32 is provided on the second machine base 3, and the second turntable 31 is rotatably connected to the outer wall of the second boss 32. The first boss 22 and the second boss 32 serve to install the transverse driving mechanism 7. The above design ensures that the rotation of the first turntable 21 and the second turntable 31 does not interfere with the transverse driving mechanism 7.

[0023] like Figure 2 and Figure 3As shown, the transverse driving mechanism 7 includes a disc seat 71, a rod seat 72, a transmission rod 73, a driving screw 74 and a second motor 76. The disc seat 71 is a carrier of the cutter disc 5. Since the cutter disc 5 is rotatably connected to the outer wall of the disc seat 71, the rotation of the cutter disc 5 is not affected by the disc seat 71. The rod seat 72 is rotatably mounted on the first boss 22, and the transmission rod 73 is rotatably mounted on the second boss 32. The rod seat 72 and the transmission rod 73 are carriers of the driving screw 74. One end of the driving screw 74 is fixedly connected to the rod seat 72, and the other end of the driving screw 74 is fixedly connected to the transmission rod 73. Since the rod seat 72 and the transmission rod 73 are both rotatably mounted, the driving screw 74 is also rotatably mounted. The second motor 76 is fixedly mounted on the second machine base 3, one end of the transmission rod 73 extends toward the direction of the second motor 76, and the output end of the second motor 76 is connected to the transmission rod 73. The second motor 76 drives the rotation of the driving screw 74 through the transmission rod 73. Limit rods 75 are respectively installed on both sides of the driving screw 74, as shown in FIG. Figure 4 The limit rod 75 is fixedly installed and parallel to the driving screw 74 (the two ends of the limit rod 75 are respectively fixedly connected to the first boss 22 and the second boss 32, and the disc seat 71 is installed on the two limit rods 75 and is threadedly connected to the driving screw 74. The limit rod 75 plays a role in limiting the movement of the disc seat 71. When the driving screw 74 rotates, the disc seat 71 can move along the length direction of the driving screw 74. The slide rod 4 determines the lateral movement direction of the cutter disc 5, and the driving screw 74 determines the lateral movement direction of the disc seat 71. The present invention sets the driving screw 74 and the slide rod 4 in parallel, so that the lateral movement direction of the disc seat 71 coincides with the lateral movement direction of the cutter disc 5, and the disc seat 71 can drive the cutter disc 5 to move laterally. Since the cutter disc 5 is rotatably installed on the disc seat 71, the lateral movement of the disc seat 71 does not affect the rotation of the cutter disc 5, and finally a lateral movement effect of the cutter disc 5 under high-speed rotation can be formed. This effect enables the cutter disc 5 to pass through the inner hole of the straight pipe in a straight line to complete the decoking operation of the inner hole wall.

[0024] like Figure 2 As shown, a height adjuster 8 is installed below the first base 2 and the second base 3. Figure 5As shown, the height adjuster 8 includes a base frame 81, a lifting screw 83 and a base support plate 84. The base frame 81 is firmly fixed to the ground to ensure the stability of the first base 2 and the second base 3 during operation. Two columns 82 are fixedly installed on the top surface of the base frame 81. A guide hole 821 is opened in the column 82. The lifting screw 83 is vertically and rotatably installed on the base frame 81. The lifting screw 83 is arranged between the two columns 82 and is arranged parallel to the columns 82. The upper end surface of the base support plate 84 is fixedly connected to the first base 2 or the second base 3 (fixed with bolts), and the lower end surface of the base support plate 84 is connected to a threaded tube 841 and two linkage rods 842. The threaded tube 841 and the two linkage rods 842 are vertically installed. The threaded tube 841 is threadedly connected to the lifting screw 83, and the two linkage rods 842 are respectively arranged corresponding to the two columns 82. The linkage rod 842 is partially inserted into the guide hole 821, and a guide plunger 843 is connected to the bottom of the linkage rod 842. The outer diameter of the guide plunger 843 matches the guide hole 821. The guide plunger 843 limits the movement of the machine base support plate 84, so that the machine base support plate 84 can only move vertically. A hand wheel 831 is fixedly connected to the bottom of the lifting screw 83, and the lifting screw 83 can be driven to rotate by turning the hand wheel 831. When the lifting screw 83 rotates, due to the limiting effect of the guide plunger 843 of the linkage rod 842, the machine base support plate 84 can only move vertically. This brings about a height adjustment effect of the first machine base 2 and the second machine base 3. In actual use, the first machine base 2 and the second machine base 3 need to be adjusted to the same height, that is, the driving screw 74 is placed horizontally, so as to ensure that the decoking operation of the pipeline inner hole can proceed smoothly.

[0025] A method for using a pipeline coking treatment device is applied to a pipeline coking treatment device, comprising the following steps: (a) Arrange and lay a plurality of pipe seats 1 in a straight line, place a straight pipe transversely on the pipe seats 1, and energize the pipe seats 1 to generate magnetic force to fix the straight pipe; (b) Select a slide bar 4, a drive screw 74, and a limit rod 75 that match the length of the straight pipe, first pre-install the slide bar 4 and the drive screw 74 and the limit rod 75 of the transverse drive mechanism 7 through the inner hole of the straight pipe, and then place the first machine base 2 and the second machine base 3 at both ends of the pipe mouth of the straight pipe respectively, pre-adjust the height adjuster 8, and roughly align the first machine base 2 and the second machine base 3 with the pipe mouth; (c) Connect the disc seat 71 on which the cutter disc 5 is installed with the driving screw 74 and the limiting rod 75. The disc seat 71 is threadedly connected with the driving screw 74 and is simultaneously installed on the limiting rod 75. All the slide bars 4 are installed on the cutter disc 5. (d) Connect the two ends of the driving screw 74 and the limiting rod 75 to the first machine base 2 and the second machine base 3 respectively, connect the two ends of the driving screw 74 to the rod base 72 and the transmission rod 73 respectively, and fix the two ends of the limiting rod 75 to the first boss 22 and the second boss 32 respectively. Connect the two ends of all the sliding rods 4 to the first turntable 21 and the second turntable 31 respectively, and fix them with bolts. At this time, the transmission structure of the cutter disc 5 and the disc base 71 has been installed; (e) Finely adjust the height of the first machine base 2 and the second machine base 3 by operating the height adjuster 8 to make the first machine base 2 and the second machine base 3 equal in height. During the height adjustment process, pre-open the transverse drive mechanism 7 to make the cutter head 5 close to the opening of the inner hole of the straight pipe, observe whether the cutter head 5 matches the size of the inner hole of the straight pipe, and adjust the height until it matches; (f) Start the rotary drive mechanism 6 to rotate the cutter disc 5 at high speed, start the transverse drive mechanism 7 to move the cutter disc 5 along the length direction of the inner hole of the straight pipe, and the high-speed rotating cutter disc 5 transversely moves through the entire inner hole of the straight pipe to complete the removal of the coking layer on the inner hole wall.

[0026] After the operation is completed, the present invention is dismantled by reverse operation, and then the straight pipe is removed and tilted or erected, and the coke layer fragments removed can be poured out. The present invention has the advantage of convenient operation and can quickly complete the decoking operation in the straight pipe.

[0027] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
