[0023] Embodiment 1

[0024] Please refer to Figure 1-6 , the present utility model provides a technical solution: an anti-blocking mechanism for an acid regeneration unit using converter gas as fuel, including a sewage discharge section 2, an electric control valve 3, a flow measurement section 4 and a driving device 9. A sewage discharge pipe 6 is fixedly installed at the front end of the sewage discharge section 2. A flow measurement section 4 is fixedly installed at the front end of the sewage discharge pipe 6. An inner connecting pipe 1 is fixedly installed at the front end of the flow measurement section 4. A tail shaft pipe 5 is fixedly installed at the rear end of the sewage discharge section 2. An inner sewage discharge spiral vane rod 10 is rotatably installed in the sewage discharge pipe 6. The tail end of the inner sewage discharge spiral vane rod 10 is rotatably installed in the tail shaft pipe 5. A driving device 9 is fixedly installed at the rear end of the tail shaft pipe 5. The output end of the driving device 9 is fixedly connected to the tail end of the inner sewage discharge spiral vane rod 10. The upper end of the sewage discharge section 2 is fixedly installed with the electric control valve 3 through a lower connecting pipe 7. An outer connecting pipe 8 is fixedly installed at the upper end of the electric control valve 3.

[0025] The sewage discharge section 2 is the central connection structure of the device and can effectively discharge the sediments discharged inside. The sewage discharge pipe 6, the sewage discharge section 2 and the tail shaft pipe 5 form an overall through structure, so that the inner sewage discharge spiral vane rod 10 installed inside can effectively discharge the sediments through its own rotation. The inner connecting pipe 1 is connected to the atomization pipeline in the furnace, and the outer connecting pipe 8 is connected to the external waste acid liquid supply equipment. The driving device 9 provides controllable power for the inner sewage discharge spiral vane rod 10. When the device discharges sewage, the electric control valve 3 can effectively close the return pipeline, thereby avoiding the blockage of the return pipeline.

[0026] Specifically, the sewage discharge section 2 includes a box section body 201. A sewage storage cavity 202 is integrally formed at the lower part of the box section body 201. An upper interface 205 is integrally formed at the upper part of the box section body 201. A front interface 203 is integrally formed at the front end of the box section body 201. A tail interface 204 is integrally formed at the rear end of the box section body 201.

[0027] The box section body 201 is the main structure of the sewage discharge section 2. The storage cavity effectively stores the sediments exported by the inner sewage spiral blade rod 10 temporarily, and then conducts unified export and cleaning. The upper interface 205 provides an installation basis for the lower connecting pipe 7. The front interface 203 provides an installation basis for the sewage pipe 6. The tail interface 204 provides an installation basis for the tail shaft pipe 5.

[0028] Specifically, the flow measurement section 4 includes a section pipe 401. A speedometer 402 is fixedly installed at the upper part of the section pipe 401. The speed measurement end of the speedometer 402 extends into the section pipe 401. A reflection lining 403 is embedded in the inner wall of the section pipe 401, and the reflection lining 403 faces the speedometer 402.

[0029] The section pipe 401 is the main structure of the flow measurement section 4 and provides an installation basis for the structures thereon at the same time. The speedometer 402 effectively monitors the flow rate therein, and the reflection lining 403 can effectively provide a better environment for the feedback monitoring of the speedometer 402.

[0030] Specifically, the driving device 9 includes a housing 901. A terminal controller 902, a servo motor 903 and a gearbox 904 are fixedly installed in the housing 901. The output end of the servo motor 903 is fixedly connected to the input end of the gearbox 904. An output shaft rod 905 is fixedly installed at the output end of the gearbox 904, and the output shaft rod 905 is fixedly connected to the tail end of the inner sewage spiral blade rod 10.

[0031] The housing 901 provides an installation basis for the internal structure. The terminal controller 902 is made based on a single-chip microcomputer and includes a motor control module, a wireless module and a WiFi module, which controls the operation of the device. The servo motor 903 outputs controllable power, and then controls the operation of the inner sewage spiral blade rod 10 through the output shaft rod 905.

[0032] Specifically, the terminal controller 902 is signal-connected to the upper computer. The terminal controller 902 is control-signal-connected to the servo motor 903 and the electric control valve 3. The terminal controller 902 is feedback-signal-connected to the speedometer 402.

[0033] The end controller 902 is connected to the host computer for signal connection, thus facilitating effective presetting of the control of the entire device. At the same time, it controls the servo motor 903 and the electric control valve 3. The tachometer 402 is connected to the end controller 902 through a feedback signal, enabling the setting of an overall control closed loop.

[0034] Specifically, a limiting edge is integrally formed inside the lower port of the sewage storage cavity 202, and a detachable sealing plate is embedded in the lower port of the storage cavity.

[0035] Through the setting of the limiting edge, the detachable sealing plate can be effectively limited and installed. The setting of the detachable sealing plate facilitates the opening of the sewage storage cavity 202, thus facilitating cleaning.

[0036] Working principle: During use, the device is connected and installed in the waste acid liquid supply pipeline of the acid regeneration hydrolysis roasting furnace, and then the circuit is connected. When the flow rate measured by the flow measurement section 4 in the pipe is less than the set threshold, it is fed back to the end controller 902 of the driving device 9, causing the electric control valve 3 to close. At the same time, the servo motor 903 drives the inner sewage discharge spiral vane rod 10 through a transmission and an output shaft rod 905. Through the operation of the inner sewage discharge spiral vane rod 10, the sundries deposited in the sewage discharge pipe 6 are effectively discharged into the sewage storage cavity 202 of the sewage discharge section 2, and then the sewage storage cavity 202 can be cleaned, thereby greatly reducing the blockage of the atomization structure in the furnace.
