Description

Technical Field

[0001] The utility model belongs to the technical field of geological experiment testing, in particular to an acid adding device for geological experiment testing mineral samples. Background Art

[0002] Geological experimental testing is a series of chemical or physical measurement operations performed in the laboratory on representative samples obtained in geological surveys. It is a scientific testing process based on experiments. When the geological industry conducts geological mineral detection, chemical reagents are usually the most common means. Acidic reagents are required to pretreat the test samples. Therefore, a large amount of acidic reagents are needed in the detection process. Acidic reagents are highly volatile and irritating, so it is necessary to use an acid adding device to add acid during the experiment.

[0003] However, in the process of using the existing acid adding device for testing mineral samples in geological experiments, backflow is prone to occur when adding acid. When backflow occurs, the amount of acid will be inaccurate, which will affect the proportion and progress of the chemical reaction. Utility Model Content

[0004] The utility model aims to provide an acid adding device for testing mineral samples in geological experiments. By setting an anti-backflow mechanism, the problem of backflow easily occurring when adding acid is solved. When backflow occurs, the amount of acid liquid will be inaccurate, thereby affecting the proportion and progress of the chemical reaction.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an acid adding device for testing mineral samples in geological experiments, comprising a rectangular bottom plate, on which an anti-backflow mechanism and a stirring mechanism are arranged;

[0007] A reactor is arranged above the rectangular bottom plate, an acid storage bottle is fixedly connected to the top of the rectangular bottom plate, a connecting pipe 1 is arranged on the top of the acid storage bottle, a water pump is fixedly connected to the top of the rectangular bottom plate, an end of the connecting pipe 1 is communicated with the water pump, a connecting pipe 2 is arranged on the top of the water pump, an end of the connecting pipe 2 is communicated with the reactor, a cover plate is threadedly connected to the top of the rectangular bottom plate, the backflow prevention mechanism comprises a fixing component and a backflow prevention component, and the fixing component comprises a cross support frame fixedly connected to the inner wall of the connecting pipe 2.

[0008] Furthermore, an adapting ring is fixedly connected to the inner wall of the second connecting pipe, and a piston is slidably connected to the inner wall of the adapting ring.

[0009] Furthermore, a telescopic rod is fixedly connected to the left side of the cross support frame, the left side of the telescopic rod is fixedly connected to the piston, a spring is sleeved on the outer wall of the telescopic rod, the right side of the spring is fixedly connected to the cross support frame, and the left side of the spring is fixedly connected to the piston.

[0010] Furthermore, the stirring mechanism includes stirring component 1 and stirring component 2, the stirring component 1 includes a rotating shaft rotatably connected to the inner wall of the bottom of the reactor, the top of the rotating shaft rotates and extends into the reactor, and a circular support plate is fixedly connected to the outer wall of the rotating shaft.

[0011] Furthermore, a motor is fixedly connected to the bottom of the rotating shaft, and two sliding rods are fixedly connected to the top of the circular supporting plate.

[0012] Furthermore, a reciprocating screw is fixedly connected to the outer wall of the rotating shaft, a reciprocating screw support rod is fixedly connected to the inner wall of the reactor, and the reciprocating screw support rod is fixedly connected to the reciprocating screw on one side close to the rotating shaft.

[0013] Furthermore, the second stirring component comprises a moving block threadedly connected to the outer wall of the reciprocating screw, the two sliding rods slide through the moving block, and a plurality of connecting rods are fixedly connected to the outer wall of the moving block.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up an anti-backflow mechanism, when the liquid passes through the connecting pipe 2, the liquid will first push the piston to move to the right and compress the telescopic rod and the spring. At this time, a gap is formed between the adapter ring and the piston, and the liquid flows into the reactor from this gap. When the water pump is turned off, the hydraulic pressure in the connecting pipe 2 is not enough to push the piston. At this time, the telescopic rod and the spring will push the piston and the adapter ring to restore the seal, avoiding the backflow of the Sunaxing solution, so that the amount of acid added to the mineral sample can be ensured to meet the experimental design requirements and is not affected by the backflow, preventing the mixed liquid after the reaction from flowing back to the acid storage container, avoiding contamination of unused acid, and ensuring the accuracy and reliability of different batches of experiments;

[0017] 2. By setting up a stirring mechanism, when the liquid is pumped into the reactor, the motor can be started. The motor drives the moving block on the reciprocating screw to move up and down while rotating through the sliding rod on the rotating shaft, and the moving block drives the stirring block through the connecting rod to stir the solution in the reactor. While stirring, the inner wall cleaning block is also driven by the connecting rod to clean the inner wall of the reactor, avoiding the adhesion of foreign matter on the inner wall of the rectangular bottom plate, so that the acid and the mineral sample can be in more sufficient and uniform contact, accelerating the speed and efficiency of the chemical reaction, and exposing the components wrapped in the sample to fully react with the acid, so that the reaction can be carried out more thoroughly.
