Detailed Description

Fig. 1 is a schematic structural view of the present invention; FIG. 2 is a schematic structural view of the dosing cock and the transmission assembly of the present invention; fig. 3 is a schematic cross-sectional view of the junction between the dosing hole and the dosing cock of the present invention. As shown in fig. 1-3, the quantitative adding mechanism for water treatment agent in the present embodiment comprises a plug seat 1, a dosing plug 2 and a transmission assembly; the plug seat 1 is provided with a dosing hole 11; the dosing faucet 2 is intersected with the dosing hole 11 and blocks the dosing hole 11 to be divided into a dosing hole and a dosing hole, the dosing faucet 2 is arranged in the faucet seat 1 in a rotating mode by taking the axis of the dosing faucet as a rotating center, and a concave part 21 for containing medicine is arranged at the position, corresponding to the dosing hole 11, of the dosing faucet 2; the power input end of the transmission assembly is in transmission connection with an external driving device, and the power output end of the transmission assembly is in transmission connection with the dosing cock 2. The external driving device drives the dosing cock 2 to rotate through the transmission assembly, the dosing hole 11 is blocked by the dosing cock 2 and is divided into a dosing hole and a dosing hole which are not communicated, the dosing hole is communicated with the outside and is used for supplementing medicaments, the dosing hole is communicated with the water treatment equipment and is used for adding medicaments for the water treatment equipment, when the concave part 21 faces upwards, the medicaments enter the concave part 21 through the dosing hole, then the concave part 21 faces downwards along with the rotation of the dosing cock 2, the medicaments enter the water treatment equipment through the dosing hole, because the medicament containing amount of the concave part 21 is fixed, the medicament adding amount of the dosing cock 2 which is rotated every time is fixed, therefore, the medicament adding amount can be directly controlled through controlling the output rotating speed of the external driving device, the medicaments are accurately and quantitatively added, and the condition of medicament waste or water treatment is avoided.

In the embodiment, the transmission assembly comprises an intermediate shaft 3 and an output shaft 4 which are in transmission connection; the output shaft 4 is coaxially fixed with the dosing cock 2; the intermediate shaft 3 is provided with a reduction gear 31, and the reduction gear 31 is engaged with a driving gear of an external driving device. The number of teeth of the reduction gear 31 is greater than that of the driving gear, and the specific numerical value is determined according to the output rotating speed of the external driving device, the medicament containing amount of the concave portion 21 and the theoretical adding amount of the water treatment medicament. The type of external driving device can be selected according to practical situations, such as a motor, an impeller mechanism arranged at the water inlet and used for converting the energy of water flowing into the kinetic energy of the rotor shaft, and the like. The transmission of gear rotation is more accurate, and is efficient, compact structure, reliable operation. The axes of the intermediate shaft 3 and the output shaft 4 are fixed in the prior art (such as a bearing seat).

In this embodiment, the intermediate shaft 3 is provided with a driving dial 32 having a cylindrical pin 32a, and the output shaft 4 is provided with a sheave 41 engaged with the driving dial 32. The driving gear of the external driving device drives the reduction gear 31 to rotate, so as to drive the intermediate shaft 3 to rotate, the intermediate shaft 3 drives the driving dial 32 to rotate, the cylindrical pin 32a on the driving dial 32 intermittently provides kinetic energy for the grooved pulley 41, the intermittent rotation of the grooved pulley 41 is realized, and finally the output shaft 4 and the dosing cock 2 also intermittently rotate, so as to provide sufficient time for the medicament to enter the concave part 21 and to be poured out from the concave part 21.

In this embodiment, the recess 21 is a cone; the dosing cock 2 is a cylinder. The cone facilitates the entry of the medicament and the pouring of the medicament out of the recess 21.

In the embodiment, the diameter and the length of the bottom surface of the cone are smaller than the side length of a square inscribed on the bottom surface of the dosing faucet 2. Since only one cylindrical pin 32a is provided on the driving dial 32, the driving dial 32 rotates four times the grooved wheel 41 to rotate one time, so the orientation of the medicine-adding rotating recess 21 is: the medicine is circulated towards the medicine inlet hole → towards the inner wall of the plug seat 1 → towards the medicine outlet hole → towards the inner wall of the plug seat 1. If the diameter length of the bottom surface of the cone is larger than the side length of the square inscribed on the bottom surface of the dosing cock 2, when the concave part 21 faces the inner wall of the cock seat 1, a gap is formed between the concave part 21 and the dosing hole 11, and if the medicament is not large particles (such as liquid or powder), the medicament will leak out to affect the accuracy of quantitative dosing of the medicament. Meanwhile, in order to ensure that the concave part 21 is not communicated with the outside when the concave part 21 faces the inner wall of the plug seat 1, a certain margin is left, and the diameter length of the bottom surface of the cone is smaller than the side length of a square inscribed on the bottom surface of the dosing plug 2.

In this embodiment, the axis of the medicine feeding hole 11 is vertical, and the medicine feeding cock 2 is vertically intersected with the medicine feeding hole 11, so that the medicine enters the concave part 21 from the medicine feeding hole and moves to the medicine discharging hole from the concave part 21 more quickly and smoothly.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
