Description

Technical Field

[0001] The present invention relates to the technical field of catalyst precursor preparation, and in particular to an In2S3 catalyst precursor preparation device and preparation method. Background Art

[0002] The steps for preparing the In2S3 precursor are as follows: weigh 0.4952In(NOs)g'xH2O and 0.7345 potassium hydrogen terephthalate (PTA), mix in a 250mL beaker and add 100mLN,N-2 methyl formaldehyde (DMF), stir until completely dissolved, transfer to an oil bath at 120°C and heat for 30min. After the reaction is completed, cool to room temperature, centrifuge (7600r / min, 6min), add anhydrous ethanol and deionized water to continue centrifugation and washing three times, and then place in a vacuum drying oven and dry at 60°C for 12h to obtain the In2S3 precursor.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

The machine tool 1 is a device carrier. The oil bath pot 101 is installed on the left part of the machine tool 1 by bolts. The rotating component 2 is installed on the eccentric position of the machine tool 1 by bolts. Three first connecting rods 21 are evenly welded around the rotating component 2. The first connecting rods 21 are all provided with a collecting mechanism 3. The machine tool 1 is provided with a feeding mechanism 4. The feeding mechanism 4 includes a liquid storage tank 41, a piston tube 43, a sleeve 44, a piston rod 441, a second elastic member 442, a connecting plate 45, a second connecting rod 46, a blocking block 47 and a feeding hopper 48. The liquid storage tank 41 is installed on the machine tool 1 by bolts, and the interior of the liquid storage tank is divided into at least two spaces. The bottom of the liquid storage tank 41 is connected to at least two pistons by bolts. Tube 43, and the bottom of the liquid storage tank 41 is connected to the piston tube 43 through a hollow tube, a one-way valve is installed on the hollow tube, the diameters of the piston tube 43 are different, the tail end of the piston tube 43 is connected to a sleeve 44, a piston rod 441 is connected to the sleeve 44, a second elastic member 442 is connected between the sleeve 44 and the piston rod 441 through a spring seat, a connecting plate 45 is welded to the end surface of the piston rod 441, a second connecting rod 46 is welded to the side of the connecting plate 45 close to the sleeve 44, a blocking block 47 is provided on the piston tube 43 closest to the second connecting rod 46, and the position of the blocking block 47 is changeable, the blocking block 47 is located in the center below the second connecting rod 46, a lower hopper 48 is installed on the machine tool 1 by bolts, and the lower hopper 48 is located below the discharge ports of all piston tubes 43.

[0027] like Figure 1-Figure 8As shown, the collecting mechanism 3 includes a rotating rod 31, a mounting plate 33, a first elastic member 34 and a beaker 35. The other end of the first connecting rod 21 is rotatably provided with the rotating rod 31 through a slide rail, and the other end of the rotating rod 31 is installed with a mounting plate 33. The first elastic member 34 is connected between the rotating rod 31 and the mounting plate 33 through a spring seat, and the beaker 35 is installed on the side of the mounting plate 33 that is not in contact with the rotating rod 31 through bolts. The discharge port of the lower hopper 48 is located above the beaker 35, and the beaker 35 is located above the oil bath pot 101.

[0028] like Figure 1-Figure 4 and Figure 6-Figure 8 As shown, the liquid storage tank 41 further includes a torsion spring 32 and a tank cover 42 . The torsion spring 32 is connected between the first connecting rod 21 and the rotating rod 31 via a spring seat. The tank cover 42 is placed on the liquid storage tank 41 .

[0029] When the present invention is to be used, the required solution is first added to the liquid storage tank 41, and then the tank cover 42 is placed on the liquid storage tank 41, and the device is started. The operator pulls the connecting plate 45 to the left, and the connecting plate 45 will move the piston rod 441 to the left. When the piston rod 441 moves to the left, the second elastic member 442 will be compressed. When the piston rod 441 moves to the left, the solution will be drawn from the liquid storage tank 41 into the piston tube 43 through the hollow tube. When the first connecting rod 21 contacts the blocking block 47 and cannot continue to move to the left, it proves that the solution in the piston tube 43 is drawn. When the solution taken has reached the standard dosage of the required solution, the connecting plate 45 is released, and the second elastic member 442 will slowly rebound to reset the piston rod 441. When the piston rod 441 is reset to the right, the solution in the piston tube 43 will be squeezed out from the head end of the piston tube 43, and the solution squeezed out from the head end of the piston tube 43 will flow into the beaker 35 along the lower hopper 48, so that the required solution dosage can be quickly and accurately extracted, which saves a lot of time and improves the efficiency of preparing the precursor. The operator manually squeezes the solution in the beaker 35. After the liquid is fully mixed, the upper end of the mounting plate 33 is pressed to make the mounting plate 33 slide up and down on the rotating rod 31, and the first elastic member 34 will be stretched. At this time, the mounting plate 33 will slide down with the beaker 35 into the oil bath pot 101. After the heating is completed, stop pressing the mounting plate 33, the first elastic member 34 will rebound and reset, and will also reset with the beaker 35. At this time, the rotating component 2 will rotate counterclockwise with the beaker 35 through the first connecting rod 21. When the rotating component 2 rotates to the top of the collection container with the beaker 35, The operator rotates the mounting plate 33 clockwise, and the mounting plate 33 will rotate with the rotating rod 31 on the first connecting rod 21. At the same time, the torsion spring 32 will be twisted by the rotation force, thereby inverting the beaker 35. At this time, the solution in the beaker 35 after the reaction is completed will be poured into the collection container. When the solution in the beaker 35 is completely poured out, the mounting plate 33 is released, and the torsion spring 32 will reset with the rotating rod 31. At the same time, the rotating rod 31 will reset with the mounting plate 33 and the beaker 35. After the work is completed, the device is closed, and the preparation of the precursor is completed.

[0030] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes an electric push rod 5, an automatic extraction mechanism 6 and a stirring device 7. The electric push rod 5 is welded on the bracket of the machine tool 1, and the electric push rod 5 is located above the beaker 35; the tail end of the second connecting rod 46 is provided with an automatic extraction mechanism 6, and the automatic extraction mechanism 6 includes a third connecting rod 61, a baffle 62 and a third elastic member 63. The tail end of the second connecting rod 46 is clamped with the third connecting rod 61, and the baffle 62 is slidably provided on the third connecting rod 61. The baffle 62 and the third connecting rod 61 are connected by a spring seat. The third elastic member 63 is connected between the baffle 62 and the third connecting rod 61; the stirring device 7 is installed on the beaker 35 by bolts.

[0031] When the operator manually mixes the solution in the beaker 35 thoroughly, the electric push rod 5 will press the beaker 35 downward to make it enter the oil bath 101 for heating. When the rotating assembly 2 rotates counterclockwise with the beaker 35 to the bottom of the lower hopper 48, the beaker 35 will contact the baffle 62, and the baffle 62 will be squeezed by the beaker 35 moving under the lower hopper 48. The third elastic member 63 will also be squeezed, so that the third connecting rod 61 moves leftward, and the third connecting rod 61 will move leftward with the second connecting rod 46 and the connecting plate 45, and the connecting plate 45 will move leftward with the piston rod 441, so that the solution can be extracted into the piston tube 43. The second connecting rod 46 will not be able to move leftward after contacting the blocking block 47. When the beaker 35 loses contact with the baffle 62, the second elastic member 442 and the third elastic member 63 will rebound. The second elastic member 442 rebounds and resets to squeeze the solution out of the head end of the piston tube 43. At the same time, the beaker 35 also moves to the bottom of the lower hopper 48. The solution flows into the beaker 35 along the lower hopper 48. The stirring device 7 is started to stir the solution in the beaker fully. The third elastic member 63 rebounds and resets the baffle 62, thereby achieving the effect that the device can automatically discharge materials without manual intervention, thereby improving the degree of automation of the device.
