[0002] Chemical production process refers to the production process of chemical processing of raw materials and finally obtaining valuable products. Due to the diversity of raw materials and products and the complexity of the production process, tens of thousands of chemical production processes are formed. Looking at the numerous chemical production processes, they are all composed of chemical (biological) reactions and physical operations. Among them, chemical reaction and reactor are the core of chemical production, and physical process plays the role of preparing suitable reaction conditions for chemical reaction and separating and purifying reactants to obtain the final product.

[0003] In some chemical production processes, the reactants need to be sampled and detected irregularly to monitor the progress of the reaction, and the rate of the chemical reaction can also be controlled through the sampling and detection results. Chemical wastewater is an important link in production detection. Chemical wastewater refers to the wastewater such as chemical wastewater, cooling water, waste gas washing water, equipment and site flushing water discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution to water bodies, thereby endangering human health and affecting industrial and agricultural production. Before the treatment of chemical wastewater, its water quality needs to be sampled and detected for targeted harmless treatment. However, at present, direct sampling is usually carried out by manual operation, and the operator directly contacts with the wastewater, and the harmful substances contained in the wastewater can cause damage to the human body.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0016] like Figure 1As shown, this utility model discloses a sampling device for chemical engineering testing, including a sampling pump 1, a transfer tank 2, a pump loader 3, and a sampling bottle 7. The inlet of the sampling pump 1 is connected to a sampling tube 4, and the right end of the outlet of the sampling pump 1 is connected to the upper part of the transfer tank 2 through a straight pipe 5. The bottom of the transfer tank 2 is connected to the pump loader 3 through a flexible hose 6. The pump loader 3 includes a base 31 and a top plate 32. The base 31 and the top plate 32 are fixedly connected by symmetrically arranged brackets 33. A spiral shaft 34 is provided between the symmetrically arranged brackets 33. The bottom of the spiral shaft 34 is rotatably connected to the base 31, and the top of the spiral shaft 34 penetrates the top plate 32. A positioning frame 35 is threadedly connected to the spiral shaft 34 between the base 31 and the top plate 32. A filling head 36 is provided on the positioning frame 35, and the flexible hose 6 is connected to the filling head 36. The two ends of the positioning frame 35 are in close contact with the symmetrically arranged brackets 33. The sampling bottle 7 is placed on the base 31.

[0017] The bottom of the spiral shaft 34 is rotatably connected to the base 31 via a bearing seat, and the top of the spiral shaft 34 is provided with a handle 37. Turning the handle 37 makes the rotation of the spiral shaft 34 more time-saving and labor-saving.

[0018] In use, the sampling tube 4 is inserted into the sampling pool, the sampling pump 1 operates, and the wastewater is pumped to the transfer tank 2. The sampling bottle 7 is placed on the base 31 on the pump maker 3. The screw shaft 34 is rotated, causing the positioning frame 35 to move downward, thereby precisely aligning the filling head 36 with the sampling bottle 7. The switch of the filling head 36 is turned on to perform sampling and filling. After completion, the switch of the filling head 36 is turned off, and the screw shaft 34 is rotated in the opposite direction to disengage the filling head 36 from the sampling bottle 7. After completion, the sampling bottle 7 is sealed to complete the sampling. The entire process ensures that the operator does not come into direct contact with the wastewater, improving sampling efficiency and reducing harm to the human body.
