Description

Technical Field

[0001] This utility model relates to the field of pH meter cleaning technology, and in particular to a pH meter cleaning and lifting device for a flow cell. Background Technology

[0002] In fields such as wastewater treatment, chemical production, and biomedicine, flow-through cells are core equipment for fluid reaction and monitoring. They often require pH meters to detect the acidity and alkalinity of fluids in real time to ensure the stability of production processes and product quality. Among these, the pH electrode, as the core sensing component of the pH meter, needs to be inserted into the flow-through cell in contact with the fluid to be tested for extended periods. Currently, most pH electrodes are fixed in place, making it impossible to flexibly adjust the insertion depth according to changes in the fluid level in the flow-through cell, testing requirements, or cleaning needs. When there are sediments or suspended impurities in the flow-through cell, the electrode at a fixed depth is easily covered by these impurities, leading to data drift. Furthermore, after long-term use, fluid residues, microbial films, or scale can easily adhere to the surface of the pH electrode, requiring manual disassembly and cleaning. This not only interrupts the testing process and reduces work efficiency but may also damage the electrode due to improper manual operation, increasing maintenance costs.

[0003] Therefore, it is necessary to provide a new pH meter cleaning and lifting device for flow-through tanks to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pH meter cleaning and lifting device for a flow-through tank.

[0008] The mounting plate is fixedly mounted with mounting brackets symmetrically distributed on both sides of the threaded rod, and the mounting brackets are fixedly mounted with servo motors for driving the threaded rod to rotate.

[0009] The mounting bracket is equipped with a rinsing component, which is located near the mounting plate. The mounting plate includes an open ring tube, and the inner wall of the open ring tube is fitted with a plurality of annularly distributed nozzles.

[0010] Preferably, a limiting rod is also fixedly installed on the mounting plate, and the limiting rod passes through the through hole of the threaded sleeve seat and is slidably connected to the through hole.

[0011] Preferably, symmetrically distributed liquid guide tubes and fixing rods are fixedly installed on the open ring tube, and the liquid guide tubes are equipped with liquid inlet ports. The ends of the liquid guide tubes and fixing rods are all fixedly installed with sleeve rings, and the sleeve rings are fixedly sleeved on the mounting frame.

[0024] 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.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 This utility model provides a flow cell pH meter cleaning and lifting device, which includes a mounting plate 1, a lifting component 3, and a rinsing component 4.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5 The mounting plate 1 is equipped with a snap ring 2 and a lifting component 3 for adjusting the height of the snap ring 2, and a threaded fastening screw 21 is inserted into the threaded through hole of the snap ring 2.

[0028] The lifting component 3 includes a threaded rod 31, which is rotatably mounted on the mounting plate 1. A threaded socket 33 with a threaded connection is fitted on the threaded rod 31. A limit rod 32 is also fixedly mounted on the mounting plate 1. The limit rod 32 passes through a through hole opened in the threaded socket 33 and is slidably connected to the through hole. A central connecting plate 34 is fixedly mounted on the threaded socket 33 and is fixedly connected to the snap ring 2. Mounting brackets 11 symmetrically distributed on both sides of the threaded rod 31 are fixedly mounted on the mounting plate 1. A servo motor 35 for driving the threaded rod 31 to rotate is fixedly mounted on the mounting brackets 11. A pH electrode 7 is inserted into the snap ring 2.

[0029] It should be noted that: after fixing the mounting plate 1 next to the flow tank, inserting the pH electrode 7 on the pH meter into the retaining ring 2, and tightening the fastening screw 21, the pH electrode 7 can be fixed in the retaining ring 2. Turn on the servo motor 35 to drive the threaded rod 31 to rotate, so that the threaded socket 33 descends along the threaded rod 31. Therefore, the pH electrode 7 can be inserted into the flow tank to detect the pH of the sewage. It can also achieve precise adjustment of the insertion depth of the pH electrode 7 to meet the depth requirements under different liquid levels and different detection scenarios.

[0030] After each detection period, the servo motor 35 is turned on to drive the threaded rod 31 to reverse, thereby driving the pH electrode 7 to rise and slide out of the flow cell. Then, the rinsing component 4 is used to rinse the pH electrode 7, thus eliminating the hidden danger of inaccurate pH detection caused by a lot of impurities adhering to the pH electrode 7.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 5 The mounting frame 11 is equipped with a rinsing component 4, which is close to the mounting plate 1. The mounting plate 1 includes an open ring pipe 41, and multiple annularly distributed nozzles 42 are installed on the inner wall of the open ring pipe 41. Symmetrically distributed liquid guide pipes 43 and fixing rods 44 are fixedly installed on the open ring pipe 41, and liquid inlet ports 431 are installed on the liquid guide pipes 43. The liquid inlet ports 431 are connected to the output pump of the clear water tank. The ends of the liquid guide pipes 43 and the fixing rods 44 are fixedly installed with sleeve rings 45, and the sleeve rings 45 are fixedly sleeved on the mounting frame 11.

[0032] A conical open ring 5 is fixedly installed on the open ring tube 41, and a conical sponge sleeve 6 is fitted on the conical open ring 5. A cut 6a is opened on the conical sponge sleeve 6, and an outward-turned ring 62 is fixedly installed on the top of the conical sponge sleeve 6 and inserted into the conical open ring 5.

[0033] It should be noted that when the pH electrode 7 rises and slides out of the flow cell, the nozzle 42 is opened, so that the nozzle 42 on the mouth ring tube 41 can thoroughly rinse the pH electrode 7, which can more thoroughly remove impurities, residues and microbial films attached to the surface of the pH electrode 7, avoid the hidden danger of inaccurate pH detection due to dirt attached to the pH electrode 7, and clean the pH electrode 7 without disassembling the pH electrode 7, which greatly shortens the maintenance time.

[0034] When the pH electrode 7 slides into the conical open ring 5, the conical sponge sleeve 6 can dehumidify the surface of the pH electrode 7. The conical cavity 61 of the conical sponge sleeve 6 can fit against the electrode surface, efficiently absorb residual moisture, and avoid the distortion of detection data caused by moisture. At the same time, the conical sponge sleeve 6 is soft and can form a buffer protection for the pH electrode 7 during the lifting and lowering process, preventing wear caused by hard contact between the electrode and the device.

[0035] In this embodiment, the design of the outward-folding ring 62 facilitates the disassembly and replacement of the conical sponge sleeve 6, reducing maintenance costs. The conical sponge sleeve 6 uses antibacterial sponge (such as polyurethane sponge with added silver ion antibacterial agent) to inhibit bacterial growth, extend the service life of the conical sponge sleeve 6, and reduce the replacement frequency. At the same time, matching Velcro can be fixed to the inner wall of the outward-folding ring 62 and the outer wall of the conical open ring 5, thereby improving the stability of the installation of the conical sponge sleeve 6.

[0036] Furthermore, a conical cavity 61 is provided inside the conical sponge sleeve 6, and the open ring tube 41, the conical open ring 5, the cut 6a of the conical sponge sleeve 6 and the connecting plate 34 are arranged on the same plane, so that when the pH electrode 7 rises, the connecting plate 34 is not restricted by the open ring tube 41, the conical open ring 5 and the conical sponge sleeve 6.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does 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.
