Description

Technical Field

[0001] This application relates to the technical field of rotary kilns, and in particular to a flow measurement device for a viscous waste oil-based slurry pipeline. Background Technology

[0002] Electromagnetic heating rotary kiln is an industrial kiln that uses the principle of electromagnetic induction for heating. It is mainly used for the heat treatment of materials, such as calcination, roasting, and drying. Compared with traditional fuel-heated rotary kilns, electromagnetic heating rotary kilns have advantages such as fast heating speed, precise temperature control, energy saving, and environmental protection.

[0003] A search revealed that Chinese Patent Publication No. CN218721511U discloses a rotary kiln, which includes an air intake combustion section disposed on a side plate and connected to an air inlet duct. This allows the combustion-supporting gas entering from the air intake combustion section to form a turbulent flow into the cylinder component after passing through the annular ventilation gap and the air inlet duct. This increases the combustion speed and ensures complete combustion of the waste inside the cylinder component, thus solving the problems of incomplete combustion and excessively long incineration time in existing rotary kilns.

[0004] Regarding the existing related technologies, the inventors discovered the following defects: During the commissioning of the system with material, it was found that the feed rate could not be accurately controlled during the feeding of viscous waste oil-based mud, the flow rate was uneven, and continuous feeding could not be guaranteed, which affected normal production. It is necessary to develop new or improve the original feeding device, otherwise it is difficult to achieve the function of continuous and stable feeding. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0022] This application discloses a pipeline flow measurement device for viscous waste oil-based mud.

[0023] like Figure 1 As shown, a flow measurement device for viscous waste oil-based mud pipeline includes a base plate 1, a feed pipe 10 is provided on the top of the base plate 1, a rotary kiln 11 is provided on one side of the feed pipe 10, and a quantitative feeding mechanism 2 is provided on the top of the base plate 1. The quantitative feeding mechanism 2 includes a feed box 214 for feeding and a feeding box 209 for feeding.

[0024] Please see Figure 4The quantitative feeding mechanism 2 includes a material box 201 fixedly installed on the top of the base plate 1, a feeding box 214 fixedly installed on one side of the material box 201, a metering pump 202 fixedly installed on the inner bottom wall of the material box 201, a conveying pipe 203 fixedly connected to the output end of the metering pump 202, and the other end of the conveying pipe 203 extending into the interior of the feeding box 209. The metering pump 202 is used to quantitatively extract materials to avoid excessive material extraction and blockage. To further explain, the metering pump 202 can be used to extract granular materials such as mortar and mud.

[0025] Please see Figure 4 A movable box 204 is fixedly connected to the top of the feed pipe 10. A threaded rod 205 is rotatably connected to the inner wall of the movable box 204. A sliding block 208 is threadedly connected to the outer wall of the threaded rod 205. A feeding box 209 is fixedly installed on the top of the sliding block 208. A motor housing 206 is fixedly installed on one side of the movable box 204. A motor 207 is fixedly installed on the inner wall of the motor housing 206. The output end of the motor 207 is connected to the threaded rod 205. The installed motor housing 206 is used to protect the motor 207 and prevent the motor 207 from being damaged by external impacts during operation.

[0026] Please see Figure 4 A driven rod 215 is fixedly installed on the inner wall of the movable box 204. The sliding block 208 is slidably connected to the driven rod 215. The driven rod 215 is used to maintain balance when the sliding block 208 moves, so as to avoid the sliding block 208 from deviating in angle during movement, which could lead to equipment damage.

[0027] Please see Figure 4 A storage box 210 is fixedly installed at the bottom of the sliding block 208. A sealing plate 211 is hinged to the bottom of the storage box 210. An intercepting plate 212 is fixedly installed on one side of the moving box 204, and the intercepting plate 212 is in contact with the sealing plate 211. An inlet 213 is opened on one side of the material box 201, and the inlet box 214 corresponds to the inlet 213. The slurry inside the material box 201 is extracted by starting the metering pump 202, and then transported through the conveying pipe 203. The material is fed into the feeding box 209, and then the starting motor 207 drives the threaded rod 205 to rotate, causing the storage box 210 to move under the action of the driven rod 215. During the movement, the blocking plate 211 is released from the interception plate 212, and the blocking plate 211 is opened, thereby feeding the feed pipe 10. This avoids the inability to accurately control the feed amount during the feeding process, which would prevent continuous feeding and affect normal production, and effectively ensures the smoothness of feeding.

[0028] A rotary connection mechanism 3 is provided on one side of the feed pipe 10. The rotary connection mechanism 3 includes a sealing gasket 303 for sealing.

[0029] Please see Figure 3 The rotary connection mechanism 3 includes a fixing ring 301 fixedly installed on one side of the feed pipe 10. A mounting groove 302 is provided on one side of the fixing ring 301. A sealing gasket 303 is fixedly installed inside the mounting groove 302. A fixing ring 306 is fixedly installed on one side of the rotary kiln 11. The fixing ring 306 is engaged with the fixing ring 301. The sealing gasket 303 is used to seal the feed pipe 10 and the rotary kiln 11 after connection, effectively improving the sealing performance.

[0030] Please see Figure 3 The inner wall of the first fixing ring 301 has multiple circular grooves 304, and steel balls 305 are rotatably connected inside the multiple circular grooves 304. An extension ring 307 is fixedly installed on one side of the second fixing ring 306, and a linkage groove 308 is opened on the outer side of the extension ring 307. The steel balls 305 are in contact with the linkage groove 308. A support box 309 is fixedly installed on the top of the bottom plate 1. A sliding groove 310 is opened on the top of the support box 309. The first fixing ring 301 and the second fixing ring 306 are in contact with the sliding groove 310. When the rotary kiln 11 rotates, the steel balls 305 are driven to rotate inside the linkage groove 308, so that the rotary kiln 11 rotates at the same time as it is connected, which effectively improves stability.

[0031] The quantitative feeding mechanism 2 is installed to feed materials quantitatively and feeds them into the rotary kiln 11 at regular intervals to avoid inaccurate control of the feed amount and uneven flow. The rotary connection mechanism 3 is used to improve stability and rotates simultaneously during connection.

[0032] The implementation principle of the viscous waste oil-based mud pipeline flow measurement device in this application embodiment is as follows: A quantitative feeding mechanism 2 is installed to feed materials quantitatively, and during feeding, materials are periodically added into the rotary kiln 11 to avoid inaccurate control of the feed amount, which could lead to uneven flow. A rotary connection mechanism 3 is used to improve stability, allowing it to rotate during connection and use. A metering pump 202 is installed to extract materials quantitatively, preventing excessive material extraction and blockage. Further explanation: The metering pump 202 can be used to extract granular materials such as mortar and mud. A motor housing 206 is installed to protect the motor 207. A driven rod 215 is installed to move the sliding block 208. During movement, maintaining balance, the slurry inside the material box 201 is extracted by starting the metering pump 202 and then transported into the feeding box 209 through the conveying pipe 203. Then, the starting motor 207 drives the threaded rod 205 to rotate, causing the storage box 210 to move under the action of the driven rod 215. During movement, the sealing plate 211 disengages from the interception plate 212, opening the sealing plate 211 to feed the feed pipe 10. The installed sealing gasket 303 is used to seal the feed pipe 10 and the rotary kiln 11 after connection. When the rotary kiln 11 rotates, the steel ball 305 rotates inside the linkage groove 308, causing the rotary kiln 11 to rotate simultaneously with the connection.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
