A device for detecting leaching solutions

Abstract

This utility model discloses a leaching solution detection device for use in the field of metal recycling. By rotating a handle, the second bevel gear drives the first bevel gear, which in turn causes a screw to move a lifting column up and down, thus accommodating different sized measuring cups. This reduces operating costs and improves practicality and applicability. A weighing sensor detects the weight of the leaching solution, the measuring cup measures its volume, and a pH sensor detects the pH value—a three-in-one detection method that enhances usability. Rotating the rotating cylinder moves the connecting rod, causing the locking connector to disengage from the locking hole. The pH sensor is then removed and replaced. The new pH sensor is installed in the fixing head, where the locking connector, under spring pressure, engages with the locking hole, securing it in place. This facilitates pH sensor replacement, reduces workload, and improves replacement efficiency.

Description

Technical Field

[0001] This utility model relates to the field of metal recycling, and in particular to a device for detecting leaching solutions. Background Technology

[0002] Metal solution recovery is an important environmental protection and resource reuse process. It mainly involves the extraction and recovery of valuable metals from waste liquid containing metal ions. By adding an appropriate leaching solution to the metal solution, the metal ions are dissolved in the form of insoluble compounds and then precipitated, thereby achieving the separation of metal from solution. Before adding the leaching solution, the pH value, volume and weight of the leaching solution need to be tested to ensure the quality of metal recovery.

[0003] Existing detection devices are not suitable for measuring cups of different sizes. When testing leachate solutions, measuring cups are generally used to hold the solution. However, the size of the measuring cups used is sometimes different, and the height of the detection devices is generally different, making it difficult to adjust to the height of the measuring cups of different sizes. When testing the pH value of leachate solutions in different sized measuring cups, it is necessary to change the detection device or measuring cup, which is cumbersome, increases the cost of use, and reduces practicality and applicability. It is also inconvenient to replace the pH sensor, which is generally installed and fixed by threads. When replacing it, tools are required for disassembly and assembly, which is cumbersome, increases the workload, and reduces the efficiency of replacement. In order to solve the above problems, we propose a leachate detection device. Utility Model Content

[0004] The purpose of this invention is to provide a leaching solution detection device, which has the advantages of being applicable to measuring cups of different sizes and facilitating the replacement of pH sensors.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a leaching solution detection device includes a housing, a battery and a main board are bolted to the inner wall of the housing, a display screen and buttons are embedded in the surface of the housing, a weighing sensor is bolted to the top of the housing, a base plate is bolted to the top of the weighing sensor, a measuring cup is placed on the top of the base plate, a fixed column is bolted to the top of the housing, a lifting column is slidably sleeved on the inner wall of the fixed column, a screw is threadedly connected to the inner wall of the lifting column, and the bottom of the screw is rotatably connected to the inner wall of the fixed column, a first bevel gear is fixedly sleeved on the surface of the screw, a second bevel gear meshes with the surface of the first bevel gear, a crank handle is fixedly sleeved at the axis of the second bevel gear, and the crank handle is rotatably sleeved with the inner wall of the fixed column.

[0006] By adopting the above technical solution, the second bevel gear drives the first bevel gear by turning the handle. The rotation of the first bevel gear causes the screw to drive the lifting column to rise and fall, thereby achieving the purpose of adapting to different sized measuring cups, reducing the cost of use, and improving practicality and applicability. The weight of the leaching solution can be detected by the weighing sensor, the volume of the measuring cup can be measured, and the pH value can be detected by the pH sensor. The three-in-one detection improves practicality.

[0007] The present invention is further configured such that: a support plate is bolted to the surface of the lifting column, an electric lifting rod is bolted to the top of the support plate, a fixing head is bolted to the output end of the electric lifting rod, a pH sensor is slidably sleeved on the inner wall of the fixing head, a rotating cylinder is rotatably sleeved on the surface of the fixing head, a snap-fit ​​connector is hinged to the inner wall of the rotating cylinder, a spring is provided between the snap-fit ​​connector and the inner wall of the fixing head, and a snap-fit ​​hole is opened on the surface of the pH sensor, and the snap-fit ​​hole snaps into the snap-fit ​​connector.

[0008] By adopting the above technical solution, rotating the rotating cylinder causes the connecting rod to move the snap-fit ​​connector, disengaging the snap-fit ​​connector from the snap-fit ​​hole. Then, the pH sensor is removed and replaced. The new pH sensor is installed into the fixing head, and the snap-fit ​​connector engages with the snap-fit ​​hole under the action of the spring, thus fixing it in place. This achieves the purpose of facilitating the replacement of the pH sensor, reducing workload, and improving replacement efficiency.

[0009] The present invention is further configured such that: a slider is bolted to the surface of the lifting column, and a groove is slidably connected to the surface of the slider, and the groove is formed on the inner wall of the fixed column.

[0010] By adopting the above technical solution, and by setting sliders and grooves, the lifting column is prevented from shifting, thus ensuring stability.

[0011] The present invention is further configured such that: a fixing plate is rotatably sleeved on the surface of the screw, and the fixing plate is bolted to the inner wall of the fixing post.

[0012] By adopting the above technical solution, the screw is fixed by setting a fixing plate to ensure stability.

[0013] The present invention is further provided that: an anti-slip pad is adhered to the top of the base plate.

[0014] By adopting the above technical solution, the measuring cup is prevented from sliding by setting an anti-slip pad, thus improving stability.

[0015] The present invention is further provided that the surface of the rotating cylinder is provided with anti-slip texture.

[0016] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0017] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0018] By adopting the above technical solution, one end of the connector is wedge-shaped, which facilitates the installation of the pH sensor.

[0019] The present invention is further configured such that the surface of the lifting column is printed with scale lines.

[0020] By adopting the above technical solution and setting scale lines, the height can be easily adjusted.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model uses a crank handle to drive a second bevel gear to drive a first bevel gear. The rotation of the first bevel gear causes a screw to drive a lifting column to rise and fall, thereby achieving the purpose of adapting to different sized measuring cups, reducing the cost of use, and improving practicality and applicability. The weight of the leaching solution can be detected by a weighing sensor, the capacity of the measuring cup can be measured, and the pH value can be detected by a pH sensor. This three-in-one detection improves practicality.

[0023] 2. This utility model uses a rotating cylinder to move the connecting rod and the snap-fit ​​connector, causing the snap-fit ​​connector to disengage from the snap-fit ​​hole. Then, the pH sensor can be removed and replaced. The new pH sensor is then installed into the fixing head, and the snap-fit ​​connector engages with the snap-fit ​​hole under the action of the spring, thus fixing it in place. This facilitates the replacement of the pH sensor, reduces workload, and improves replacement efficiency. Attached Figure Description
