Description

Technical Field

[0001] The utility model relates to the technical field of wastewater filtration, in particular to a sampling device for electroplating wastewater. Background Technique

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the principle of electrolysis. It is a process of making the surface of metal or other material parts adhere to a metal film by electrolysis to prevent metal oxidation (such as rust). During electroplating, the coating metal or other insoluble materials are used as anodes, and the workpiece to be plated is used as a cathode. The cations of the coating metal are reduced on the surface of the workpiece to be plated to form a coating. To exclude the interference of other cations and make the coating uniform and firm, a solution containing cations of the coating metal is used as the electroplating solution to keep the concentration of the cations of the coating metal unchanged. The purpose of electroplating is to deposit a metal coating on the substrate to change the surface properties or dimensions of the substrate. Electroplating can enhance the corrosion resistance of metals (the coating metal is mostly made of corrosion-resistant metals), increase hardness, prevent wear, improve electrical conductivity, smoothness, heat resistance and surface beauty. Electroplating wastewater is various wastewater discharged during the electroplating production process. The sources of electroplating wastewater are generally cleaning water for plated parts, waste electroplating solution and other wastewater. According to the production section and plating type, electroplating wastewater can be divided into multiple categories. For the convenience of disposal, the wastewater must be discharged in a standardized manner according to the categories (separate discharge of different qualities).

[0003] When the existing technology samples wastewater, in order to measure the amount of water, it is necessary to quantify the sampled wastewater when quantitative detection is required, which is rather troublesome. Therefore, a sampling device for electroplating wastewater is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sampling device for electroplating wastewater, which solves the problems put forward in the background technique.

[0005] The embodiment of the present application provides a sampling device for electroplating wastewater, including a device main body, a knob is rotatably installed on the device main body, an annular plate is fixedly installed on the device main body, a sampling head is arranged at the lower end of the device main body, a pulling block is arranged on the annular plate, a display meter is arranged on the device main body, scales are arranged on the display meter, and a pointer is arranged on the display meter.

[0006] In this technical solution, the sampling head is inserted into the wastewater, and the knob is rotated. When the knob rotates, it drives the threaded rod to rotate, thereby driving the sleeve to move, and then driving the piston to move to sample the wastewater. When the piston moves, it drives the rack to move. When the rack moves, it drives the gear to rotate. When the gear rotates, it drives the rotating rod to rotate, thereby driving the rotating shaft to rotate, and then driving the pointer to rotate. The pointer can display the scale to show the volume of the sampled wastewater. When the sampling head needs to be replaced due to corrosion after long-term use, pressing the pull block will drive the clamping rod to move. When the thin rod aligns with the circular groove and the rectangular groove, it can be disassembled. When replacing the new sampling head, press the pull block and then remove the external force. The clamping rod will be driven to reset under the action of the spring to install the sampling head.

[0007] Optionally, an inner cavity is provided inside the device body. The lower end of the knob is fixedly installed with a threaded rod, and a sleeve is threadedly installed on the threaded rod. The other end of the sleeve is fixedly installed with a piston.

[0009] Optionally, a rack is fixedly installed on the piston.

[0010] By adopting the above technical solution, when the piston moves, it drives the rack to move.

[0011] Optionally, a rotating shaft is provided on the pointer. The rotating shaft passes through the device body and is fixedly installed with a rotating rod, and a gear is fixedly installed on the rotating rod.

[0012] By adopting the above technical solution, when the gear rotates, it drives the rotating rod to rotate, thereby driving the rotating shaft to rotate, and then driving the pointer to rotate.

[0013] Optionally, the gear and the rack mesh with each other.

[0014] By adopting the above technical solution, when the rack moves, it drives the gear to rotate.

[0015] Optionally, a connecting pipe is fixedly installed on the sampling head. An installation plate is fixedly installed on the sampling head, and a clamping plate is fixedly installed on the installation plate.

[0016] By adopting the above technical solution, the sampled wastewater can be transported to the device body through the sampling head via the connecting pipe.

[0017] Optionally, a clamping rod is provided at the other end of the pull block. The clamping rod includes a thick rod and a thin rod. A spring is fixedly installed on the thick rod, and the other end of the spring is fixedly installed on the annular plate.

[0018] By adopting the above technical solution, pressing the pulling block will drive the clamping rod to move, and when the external force is removed, the clamping rod will be driven to reset under the action of the spring.

[0019] Optionally, a rectangular groove and a circular groove are formed in the clamping plate. The width of the rectangular groove is greater than the diameter of the spring and less than the diameter of the thick rod, and the diameter of the circular groove is the same as the diameter of the thick rod.

[0020] By adopting the above technical solution, when the thick rod on the clamping rod corresponds to the circular groove, the sampling head will be fixed on the device main body.

[0021] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:

[0022] Through the setting of the display table in the technical solution of the present application, the sampled water volume can be observed. By setting a sampling head that is easy to replace, it is easier to replace the sampling head after it is corroded after multiple uses. The structures cooperate with each other, saving time and being more efficient. Description of the Drawings
