Abstract

The chemical centrifuge machine is an instrument for a chemical laboratory that will rotate the test tubes many times, in one rotation movement, for each turn that will be rotated in another translation movement. To increase the number of turns of each of these two movements, a gear-cone train is added that will multiply the number of turns that the electric motor can rotate to its axis.

DESCRIPTION

Chemical centrifuge machine.

Object of the invention

The main objective of the present invention is to ensure that a chemical reaction precipitates more rapidly, which can be achieved by increasing the rotational movement that we apply to the test tube where the reagents are installed. In the present invention, we produce a double movement of translation and rotation to the circular box (4) where we place the test tubes.

Background of the invention

The main antecedent of the present invention are some of the machines used in chemical laboratories that apply a rotational movement, or a vibratory movement, on the test tubes. In the invention that is proposed today, there is a double movement, of translation and rotation, to these test tubes, in a machine that will consume little energy and that can make them rotate many turns in rotation for each turn they turn in translation.

Description of the invention

The chemical centrifuge machine, in its essential version, is formed by a small electric motor located vertically (1) at the end of which two rings (2, 18) are installed that are fixed horizontally at a point on its perimeter, to two others perpendicular axes (3) that hold, above and below, a circular box (4), which has teeth in its perimeter, inside which the chemical reagents will be placed. These teeth are to be engaged with the teeth of another cogwheel (5) around them. In this way, the machine will produce a double movement of translation and rotation, which will affect the result of the chemical reaction that is intended to be put into play, because the number of turns in rotation that will rotate the box (4) will be much greater than the one of its turn in translation. The test tubes will be placed inside this box (4), and, they can be placed and removed by the upper face. We must try to increase, now, the number of turns per second that this circular box (4) gives, with its test tubes. To achieve this, first of all, we will have to change the position of the electric motor (1), and add a sprocket (17) that we will put on the upper ring (2). In figure 2 almost all the elements of the chemical centrifuge machine are represented, with the exception of the outer ring (5), which I have not placed in this figure, just for greater visual comfort. The outer ring (5) is still present. What we are going to do now, is to add a gear train-cone (12-16), between the engine (1) and the wheel (17) that we have added on the upper ring (2). As always, we form a first gear-cone between the motor shaft (1) and its cogwheel (11). Next, we put two or more cone-gears (12-13) and (15-16), of which in figure 2 I have only represented two, placing an intermediate wheel (14) between the crown (13) of the first gear-cone (10, 12, 13) and pinon (15) of the second gear-cone (15-16). The last crown (16) of this last gear-cone (15-16), -or, the crown of the last gear-cone that we put on the train-, is engaged with the teeth of the wheel (17) added on the ring (2), so that when this wheel (17) turns, the rings (2, 18) will turn, and the circular box (4) that has the reagents in the test tubes will also rotate, because the teeth of the box (4) will be in permanent contact with

the teeth of the outer ring (5). With this gear train-cone, the box (4) can rotate many more turns per second. If we want to get the motor to reduce energy consumption, we will add a transformer generator (7-9) connected to the plug (6). The cables of the plug (6) form an inductor coil (7) of only one or two turns, which are wound on the core (8) of soft iron, while the motor cables (1) also form another induced coil (9 ) in that same core (8), which will have the same number of turns as the inductor coil (7). With this generator, the current consumed by the motor (1) will only be induced energy, while the energy that comes through the plug (6), will enter the inductor coil (7) and will leave it as if it were circulating through any straight section of the circuit, because, the current, runs through its single-spiral cable, without affecting any component of the circuit of the centrifuge machine that only connects to the induced coil (9).

Description of a preferred embodiment

The chemical centrifuge machine, is characterized by being an instrument for chemistry laboratory that produces two simultaneous movements, one of translation and another of rotation. Two rings (2, 18) that rotate, rotate a circular box (4) that carries the test tubes with the chemical reagents, so that the reaction will precipitate much earlier, and, it will do so much sooner the higher the number of turns in rotation that the box can rotate (4). The teeth of the box (4), are meshed with the teeth of the inner face of the toothed ring (5), so that when the rings (2, 18) turn, the box (4) will also rotate, and, it will take many more turns per second than the rings (2, 18), depending on the proportion existing between the respective diameters of this kind of "pinon" that is the box (4), and, this "crown" that are the rings (2, 18). If the diameter of the rings (2, 18) is about (30) cm, and, that of the box (4) is (5) cm, the box (4) will rotate about (6) turns for each lap that turn the rings (2, 18), so that if the motor (1) causes the rings (2, 18) to rotate (8) turns per second, the box (4) will turn (48) turns per second. Suppose that between the box (4) and the outer ring (5) the difference in diameter is tripled, and, in addition, instead of putting only two gear-cone, in the gear-cone train, we put four, or, five . With four cone-gears, for each turn the motor shaft rotates, - that is, its cogwheel (11) -, pinon (12) can rotate (3) turns. Thus, the next gear-cone rotate it (9) turns, and, the next, turn it (27) turns, so that if the wheel (11) turns (8) turns / second, the wheel (17) of the upper ring ( 2) turn (27 x 8 = 216) turns / second. And, as before, if for each turn the rings rotate (2, 18), the box (4) rotates six times, the total number of turns the box (4) now rotates, will be (216x 6 = 1,296) turns per second.
