Description

Technical Field

[0001] This utility model relates to the technical field of carbon storage tank conveying pipelines, specifically a rinsing structure and a carbon storage tank conveying pipeline for tanning wastewater treatment. Background Technology

[0002] Carbon storage tanks in tannery wastewater treatment are primarily used to store and manage carbon sources for biological treatment processes. In tannery wastewater, the concentration of organic matter may be unstable and insufficient to support efficient biological treatment. Therefore, it is necessary to add readily degradable carbon sources (such as methanol and acetic acid). The carbon storage tank is the container used to store these supplementary carbon sources. Typically, an external carbon tanker truck pumps the carbon source into the storage tank via a pump and input pipeline. The storage tank is also connected to an output pipeline, which connects to an anoxic tank. When the anoxic tank needs additional carbon source, a metering pump delivers a measured amount of carbon source to the anoxic tank through the output pipeline.

[0003] Currently, patent CN216890301U discloses a carbon source dosing system, belonging to the field of wastewater treatment. This system adds a carbon source storage tank and a dosing unit to the wastewater treatment process. The dosing unit extracts carbon source from the storage tank and inputs it into the reverse digestion filter via the carbon source dosing system. The system includes two sets of metering pumps and one standby pump, enabling uninterrupted operation in case of emergencies. A flow meter further stabilizes the carbon source input, allowing for adjustments to the peak flow rate based on site conditions, thus achieving controlled carbon source application. This device enables controllable carbon source dosing, thereby improving work efficiency.

[0004] The storage tank in the above-mentioned device can be filled with carbon source through a conveying pipeline. However, the conveying pipeline has the following shortcomings: the liquid carbon source may contain impurities such as suspended solids and particulate matter, and a scale layer may form on the inner wall of the pipeline, which will reduce the flow area of ​​the pipeline, increase the risk of blockage, and cause inconvenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rinsing structure and a carbon storage tank conveying pipeline for tanning wastewater treatment, which facilitates the rinsing and soaking of impurities adhering to the inside of the carbon tank's output pipeline.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flushing structure, including a flushing assembly connected to the outside of a conveying pipe located outside the carbon storage tank. The flushing assembly includes control valve structures connected to both ends of the conveying pipe. A first branch pipe is connected to the outer wall of the conveying pipe near the carbon storage tank. A water source pipe is also connected to the outside of the first branch pipe. A third solenoid valve is sealed between the water source pipe and the first branch pipe via a flange. A second branch pipe is connected to the outer wall of the end of the conveying pipe. A water outlet pipe is connected to the outer wall of the second branch pipe. A fourth solenoid valve is sealed between the water outlet pipe and the second branch pipe via a flange. A monitoring assembly is also connected to the outer wall of the conveying pipe. An external water source device is connected to the outer end of the water source pipe.

[0007] Furthermore, the control valve body structure includes a first solenoid valve and a second solenoid valve. A carbon tank output pipe is fixedly connected to the outer wall of the carbon storage tank. The two ends of the first solenoid valve are sealed to the ends of the carbon tank output pipe and the conveying pipe through flanges. The end of the conveying pipe is also connected to a dispensing pipe. The two ends of the second solenoid valve are sealed to the ends of the dispensing pipe and the conveying pipe through flanges.

[0008] Furthermore, the monitoring component includes multiple ultrasonic thickness detectors, which are electrically connected to a monitoring control unit via cables. The monitoring control unit is fixedly installed to the outer wall of the delivery pipe using fasteners.

[0009] Furthermore, a branch pipe is connected to the outside of the first branch pipe, and a gas source pipe is connected to the outer end of the branch pipe. A fifth solenoid valve is sealed between the gas source pipe and the branch pipe through a flange, and an external gas generating device is connected to the outer end of the gas source pipe.

[0010] Furthermore, the gas generating device can be an air compressor.

[0011] Furthermore, the first, second, third, and fifth solenoid valves are all electrically connected to the control unit in the carbon storage tank conveying system via cables.

[0012] This utility model also provides a carbon storage tank conveying pipeline for tanning wastewater treatment, which also includes the above-mentioned flushing structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes an ultrasonic thickness detector, a first branch pipe, a third solenoid valve, a second branch pipe, and a fourth solenoid valve to work together to open and close the flushing pipe. By connecting an external water source, the conveying pipe can be soaked and flushed, preventing the flow rate from being reduced due to deposits formed during the carbon source transport process. This further ensures the amount of carbon source added to the conveying pipe, avoids blockages that could cause downtime, and eliminates the need for manual disassembly and separate flushing of the conveying pipe, saving manpower.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a flushing structure includes a flushing assembly connected to the outside of a conveying pipe 1 located outside the carbon storage tank 2. The flushing assembly includes control valve body structures connected to both ends of the conveying pipe 1. A first branch pipe 5 is connected to the outer wall of the conveying pipe 1 near the carbon storage tank 2. A water source pipe 7 is also connected to the outside of the first branch pipe 5. A third solenoid valve 51 is sealed between the water source pipe 7 and the first branch pipe 5 through a flange. A second branch pipe 6 is connected to the outer wall of the end of the conveying pipe 1. A water outlet pipe 62 is connected to the outer wall of the second branch pipe 6. A fourth solenoid valve 61 is sealed between the water outlet pipe 62 and the second branch pipe 6 through a flange. A monitoring assembly is also connected to the outer wall of the conveying pipe 1. An external water source device is connected to the outer end of the water source pipe 7.

[0022] like Figure 1 As shown, the rinsing structure and the carbon storage tank conveying pipeline for tanning wastewater treatment in this utility model are similar in structure to existing carbon source dosing systems. For example, patent publication number CN216890301U discloses a carbon source dosing system. The main improvement of this utility model is that it facilitates the rinsing and soaking of impurities adhering to the inside of the carbon tank's output pipeline. Figures 1 to 4 As shown, when the flushing structure and the carbon storage tank conveying pipeline for tanning wastewater treatment in this utility model are in use, the third solenoid valve 51 and the fourth solenoid valve 61 are both in the closed state when the conveying pipe 1 is normally conveying carbon source, that is, the first branch pipe 5 and the second branch pipe 6 are closed, and the conveying pipe 1 is conveying normally at this time.

[0023] Because a monitoring component is provided on the outside of the conveying pipe 1, the thickness of impurities on the inner wall of the conveying pipe 1 is monitored by the monitoring component. When the thickness exceeds the threshold set by the monitoring component, a prompt will be issued. At this time, the worker can drain the liquid carbon source in the conveying pipe 1 and close the control valve body structure, so that the conveying pipe 1 is cut off from the conveying state.

[0024] At this time, the third solenoid valve 51 and the external water source connection device at the outer end of the first branch pipe 5 are opened, so that the external water source connection device can send the clean water into the delivery pipe 1 through the first branch pipe 5. When the clean water is continuously delivered, the fourth solenoid valve 61 of the second branch pipe 6 is closed, so that the clean water can fully soak and soften the inner wall of the delivery pipe 1.

[0025] After soaking for a period of time, open the fourth solenoid valve 61 on the second branch pipe 6 to allow the clean water and impurities to be discharged through the outlet pipe 62.

[0026] At the same time, the third solenoid valve 51 and the fourth solenoid valve 61 can be opened simultaneously to continuously flush the delivery pipe 1 with clean water, thus improving the flushing effect.

[0027] The opening and closing of the flushing pipe is achieved through the cooperation of the first branch pipe 5, the third solenoid valve 51, the second branch pipe 6, and the fourth solenoid valve 61. By connecting to an external water source, the conveying pipe 1 can be soaked and flushed, avoiding the formation of deposits during the conveying of carbon source and thus preventing a reduction in flow rate. This further ensures the amount of carbon source added to the conveying pipe 1, preventing blockages that could lead to machine shutdown. There is no need for manual disassembly of the conveying pipe 1 for separate flushing, saving manpower.

[0028] like Figures 1 to 2As shown, the control valve body structure includes a first solenoid valve 11 and a second solenoid valve 12. The outer wall of the carbon storage tank 2 is fixedly connected to a carbon tank output pipe 21. The two ends of the first solenoid valve 11 are sealed to the ends of the carbon tank output pipe 21 and the conveying pipe 1 through flanges. The end of the conveying pipe 1 is also connected to a dispensing pipe 3. The two ends of the second solenoid valve 12 are sealed to the dispensing pipe 3 and the end of the conveying pipe 1 through flanges.

[0029] Specifically, by driving and closing the first solenoid valve 11 and the second solenoid valve 12, the carbon source delivery channel of the delivery pipe 1 can be cut off.

[0030] like Figures 1 to 2 As shown, the monitoring component includes multiple ultrasonic thickness detectors 4, which are electrically connected to a monitoring control unit 41 via cables. The monitoring control unit 41 is fixedly installed to the outer wall of the delivery pipe 1 by fasteners.

[0031] Specifically, in order to detect the thickness of the inner wall of the conveying pipe 1, a multi-node ultrasonic thickness detector 4 is used to detect the thickness of impurities on the inner wall of the conveying pipe 1. The roller type, in conjunction with the monitoring and control unit 41, can issue a prompt to the staff to perform a flushing operation on the pipe.

[0032] like Figure 4 As shown, a branch pipe 8 is connected to the outside of the first branch pipe 5. A gas source pipe 9 is connected to the outer end of the branch pipe 8. A fifth solenoid valve 81 is sealed between the gas source pipe 9 and the branch pipe 8 through a flange. An external gas generating device is connected to the outer end of the gas source pipe 9.

[0033] Specifically, after the conveying pipe 1 has been rinsed, in order to improve the drying efficiency of the water stains in the conveying pipe 1, the third solenoid valve 51 can be closed and the fifth solenoid valve 81 can be opened, so that the first branch pipe 5 is closed and the branch pipe 8 is opened. Then the gas generator is turned on, so that the gas enters the branch pipe 8 through the gas source connector 9, passes through the first branch pipe 5 and reaches the conveying pipe 1. At this time, the fourth solenoid valve 61 on the second branch pipe 6 is in the open state. This setting allows the water stains in the conveying pipe 1 to be dried by the gas, thereby improving the drying efficiency of the water stains inside the conveying pipe 1, so as to put it into the carbon source conveying work as soon as possible.

[0034] like Figures 1 to 2 As shown, the gas generating equipment can be an air compressor. The air compressor can deliver compressed gas into the gas source connector 9.

[0035] like Figures 1 to 2 As shown, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 51 and the fifth solenoid valve 81 are all electrically connected to the control unit in the carbon storage tank 2 conveying system via cables.

[0036] Specifically, in order to make the above-mentioned solenoid valve structure easy to drive, it can be electrically connected to the control unit in the carbon storage tank conveying system, which greatly improves the ease of operation.

[0037] In the above structure, the solenoid valve structure, air compressor equipment, and ultrasonic thickness gauge 4 are all existing mature technologies, so they will not be described in detail here.

[0038] This utility model also provides a carbon storage tank conveying pipeline for tanning wastewater treatment, which also includes the above-mentioned flushing structure.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
