Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and in particular to a monitoring device for the discharge of waste liquid from acid-soluble phosphorus recovery treatment. Background Technology

[0002] Acid-dissolving phosphorus recovery is a method that uses acidic conditions to dissolve and recover phosphorus resources from wastewater using specific technologies. It is mainly used for the treatment and resource utilization of phosphorus pollution in industrial wastewater (such as from phosphate chemical, electroplating, and fertilizer production) or domestic wastewater. During this process, according to national environmental protection requirements, the wastewater generated must be tested and monitored to ensure it meets environmental standards before discharge.

[0003] The existing methods for detecting and monitoring waste liquid generally involve using sampling devices to transfer the waste liquid to a water quality analyzer for detection and monitoring. This method cannot achieve real-time monitoring of water quality, thus reducing the effectiveness of monitoring the discharged waste liquid.

[0004] Therefore, it is necessary to provide a new monitoring device for the discharge of waste liquid from acid-soluble phosphorus recovery treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a monitoring device for the discharge of waste liquid from acid-soluble phosphorus recovery treatment.

[0006] The acid-soluble phosphorus recovery wastewater discharge monitoring device provided by this utility model includes: an inlet pipe, with connecting pipes fixedly installed on both sides inside the inlet pipe, and a detection cylinder fixedly connected to and communicating with the two connecting pipes at their ends, and a detection component installed on the detection cylinder.

[0007] The detection assembly includes a support frame, which is fixedly installed on the outer wall of the detection cylinder. A water quality detector is fixedly connected to the top of the support frame. The water quality detector has two electrically connected detection heads, which are movably inserted into the detection cylinder.

[0008] Preferably, the top of the detection cylinder has an installation groove, a sealing cover is inserted into the installation groove, a cleaning frame is fixedly installed on the side of the sealing cover near the detection cylinder, the cleaning frame is located inside the detection cylinder, and the cleaning frame has symmetrically distributed cleaning holes inside.

[0009] Preferably, a guide hole is provided inside the sealing cover at the location opposite to the cleaning hole, and the inner walls of both the guide hole and the cleaning hole abut against and slide against the outer wall of the detection head.

[0010] Preferably, the detection head is fixedly mounted with a cylinder at the end of the sealing cover, and the top of the cylinder is fixedly connected to the inner top of the support frame.

[0011] Preferably, hydraulic cylinders are fixedly installed on both sides of the top of the sealing cover, and the top of the hydraulic cylinders is fixedly connected to the inner top of the support frame.

[0012] Preferably, a drain pipe communicating with the inside of the detection cylinder is fixedly installed on the side away from the water inlet pipe, and a drain valve is fixedly installed on the drain pipe.

[0013] Preferably, a return pipe is fixedly installed between the internal detection cylinder and the drain valve of the drain pipe, and a return valve is fixedly installed on the return pipe.

[0014] Preferably, the water inlet pipe is a tee pipe, and a control valve is fixedly connected to each of the parts of the water inlet pipe opposite to the two side adapter pipes.

[0015] Compared with related technologies, the acid-soluble phosphorus recovery wastewater discharge monitoring device provided by this utility model has the following advantages:

[0016] 1. By connecting the inlet pipe to the waste liquid discharge pipe of the recycling and treatment device, the detection head of the detection cylinder can monitor the internal flowing waste liquid in real time without the need to sample and test the waste liquid, thus improving the accuracy and efficiency of the device's detection.

[0017] 2. By designing the movable movement of the detection head, this utility model allows the detection heads on both sides to swing up and down in the cleaning hole during use through the staggered extension and retraction of each cylinder. During this process, the cleaning hole can clean the impurities adsorbed on the outer wall of the detection head by abutting against it. This not only reduces the impact of impurities on the detection accuracy of the detection head, but also reduces the corrosion caused by impurities adhering to the detection head.

[0018] 3. With the addition of a return pipe, this utility model allows the drain valve to be closed and the return valve to be opened when the terminal controller detects that the discharged waste liquid is substandard through the water quality tester during use. This enables the flowing waste liquid to be returned for further treatment through the return pipe.

[0019] 4. During use, when the water quality analyzer on one side needs maintenance, the control valve on the side requiring maintenance can be closed and the control valve on the other side opened, thereby changing the flow path of the wastewater and allowing the water quality analyzer on the other side to perform the test. Therefore, the device can perform continuous testing without shutting down. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 5 The present invention provides a monitoring device for the discharge of waste liquid from acid-soluble phosphorus recovery treatment. The monitoring device includes: an inlet pipe 1.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 5Both sides of the inlet pipe 1 are fixedly installed with connecting pipes 11. The ends of the two connecting pipes 11 are fixedly connected to and communicate with the inside of the pipes 11. The detection cylinder 3 is equipped with a detection component 4. The detection component 4 includes a support frame 41, which is fixedly installed on the outer wall of the detection cylinder 3. A water quality detector 42 is fixedly connected to the top of the support frame 41. The water quality detector 42 is equipped with two electrically connected detection heads 421, which are movably inserted into the detection cylinder 3. A drain pipe 2 is fixedly installed on the side of the detection cylinder 3 away from the inlet pipe 1 and communicates with the inside of the pipe. A drain valve 21 is fixedly installed on the drain pipe 2. A return pipe 5 is fixedly installed between the detection cylinder 3 and the drain valve 21 inside the drain pipe 2. A return valve 51 is fixedly installed on the return pipe 5. The inlet pipe 1 is a three-way pipe, and a control valve 12 is fixedly connected to the part of the inlet pipe 1 opposite to the two connecting pipes 11.

[0030] It should be noted that by connecting the water inlet pipe 1 to the waste liquid discharge pipe of the recycling and treatment device, the detection head 421 of the detection cylinder 3 can monitor the internal flowing waste liquid in real time without sampling and testing the waste liquid, thus improving the accuracy and efficiency of the device's detection.

[0031] It should also be noted that: by setting up the return pipe 5, during use, when the water quality detector 42 detects that the discharged sewage is unqualified, it can control the corresponding drain valve 21 to be closed and the corresponding water flow valve to be opened, so that the unqualified wastewater can be returned through the return pipe 5 for reprocessing.

[0032] By installing a control valve 12 on the inlet pipe 1, the flow path of wastewater can be changed by opening or closing the control valve 12 during subsequent use. In this way, when it is necessary to repair and maintain the water quality analyzer 42 on one side, the water quality monitoring component on the other side can perform real-time detection, thereby realizing uninterrupted detection of wastewater.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 5 The top of the inner part of the detection cylinder 3 is provided with an installation groove 31. A sealing cover 43 is inserted into the installation groove 31. A cleaning frame 44 is fixedly installed on the side of the sealing cover 43 near the detection cylinder 3. The cleaning frame 44 is located inside the detection cylinder 3 and has symmetrically distributed cleaning holes 441 inside. A guide hole 432 is provided inside the sealing cover 43 opposite to the cleaning hole 441. The inner walls of the guide hole 432 and the cleaning hole 441 are abutted against and slidably connected to the outer wall of the detection head 421. A cylinder 422 is fixedly installed at the end of the detection head 421 located on the sealing cover 43. The top of the cylinder 422 is fixedly connected to the top of the support frame 41. Hydraulic cylinders 431 are fixedly installed on both sides of the top of the sealing cover 43. The top of the hydraulic cylinders 431 is fixedly connected to the top of the support frame 41.

[0034] It should be noted that: with the hydraulic cylinder 431 in use, the working hydraulic cylinder 431 can drive the sealing cover 43 to move, thereby smoothly controlling the sealing state of the sealing cover 43 on the mounting groove 31. With the pneumatic cylinder 422 in use, the working pneumatic cylinder 422 will drive the detection head 421 to move vertically. During the movement of the detection head 421, the cleaning hole 441 in the cleaning frame 44 will scrape and clean the impurities adhering to the detection head 421 by abutting against the outer wall of the detection head 421, thereby reducing the impact of impurities adhering to the detection head 421 on the detection effect during use. In order to avoid physical scratches to the detection head by the cleaning hole 441 during the cleaning process, a gasket of flexible material can be set on the inner wall of the cleaning hole 441.

[0035] The working principle of the acid-soluble phosphorus recovery and waste liquid discharge monitoring device provided by this utility model is as follows:

[0036] When using this device, first connect the inlet pipe 1 in the device to the discharge pipe in the acid-soluble phosphorus recovery treatment device, and connect the return pipe 5 to the recovery treatment device.

[0037] Then the control valve 12 on one side can be opened, so that when the waste liquid generated by the recycling and treatment device is discharged, the outflowing waste liquid will flow into the transfer pipe 11 and the detection cylinder 3 connected to it through the water inlet pipe 1, and then flow into the drain pipe 2 through the detection cylinder 3 until it is discharged out through the drain pipe 2.

[0038] When wastewater enters the detection cylinder 3, the water quality detector 42 monitors the flowing waste liquid in real time through the detection head 421 located inside the detection cylinder 3, and transmits the detected data to the terminal controller in real time. At this time, the terminal controller can monitor the data. When the detected data is unqualified, the drain valve 21 can be closed, and the return valve 51 on the corresponding return pipe 5 can be opened, so that the wastewater can be returned to the acid-soluble phosphorus recovery treatment device through the return pipe 5 for further treatment.

[0039] Furthermore, during use, one cylinder 422 in the detection assembly 4 can be controlled to retract, and another cylinder 422 can be controlled to extend. The working cylinder 422 will drive the detection head 421 to slide inside the guide hole 432 and the cleaning frame 44. At this time, the cleaning hole 441 inside the cleaning frame 44 will scrape and clean the impurities on the outer wall of the detection head 421 by abutting against it, thereby avoiding the adhesion of impurities on the detection head 421 and the impact on the subsequent detection effect of the detection head 421.

[0040] When the detection component 4 needs to be inspected and maintained later, the control valve 12 corresponding to the working detection component 4 can be closed, and the control valve 12 on the other side can be opened at the same time. This allows the waste liquid to be guided to flow to the outside of the detection head 421 in the other detection component 4, so that the other detection component 4 can perform detection work without stopping the operation of the acid-soluble phosphorus recovery treatment device, thus achieving non-stop operation.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
