Description

Technical Field

[0001] The invention relates to the technical field of mineral product production, and in particular to a mineral dressing dosing device with an encoder. Background Art

[0002] Ore dressing is the process of crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore, and then using gravity separation, flotation, magnetic separation, electrostatic separation and other methods to separate useful minerals from gangue minerals, and to separate various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, so as to obtain the raw materials needed for smelting or other industries.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention provides a medicine box, a connecting seat, a telescopic inner tube, a telescopic bottom tube, a retaining seat, a liquid spiral tube, a flow changing assembly, an inner tube, a rotating shaft ring and a spiral inner groove. The medicine flows in the inner ring, contacts with a plurality of rotating shaft rings and drives them to rotate. A spiral water flow is generated during the circulation process, which improves the circulation effect of the medicine and avoids air blockage caused by poor discharge of air originally existing in the pipeline during the circulation process, thereby affecting the subsequent medicine transportation. The flow changing assembly can be used to change the circulation state of the medicine in the inner tube to form a spiral airflow, thereby improving the circulation effect of the medicine after entering the inner tube and avoiding the formation of a counter-airflow when the medicine first enters the inner tube due to the inability to discharge the air existing inside in time, thereby ensuring the subsequent circulation speed of the medicine. The spiral inner groove can improve the contact effect between the medicine and the rotating shaft ring, thereby driving the rotating shaft ring to rotate and forming a rotating water flow.

[0017] 2. The present invention provides an upper connecting tube and a liquid inlet assembly. During the process of medicine entering through the liquid inlet assembly, due to the infusion of medicine, the liquid inlet seat slides in the upper connecting tube due to the force of the medicine circulating. During the downward sliding of the liquid inlet seat, the reset spring is squeezed and elastically deformed. Under the combined force of the reverse force of the reset spring and the infusion of medicine, the liquid inlet seat shakes up and down, thereby improving the entry effect of the medicine. The liquid inlet assembly can be used to cause the liquid inlet seat to be in a frequent vibration state during the infusion of medicine, thereby ensuring the smoothness of the medicine circulation process, avoiding the obstruction of the medicine entering the liquid inlet seat due to the tension of the medicine, affecting the flow rate of the medicine, and thus reducing the discharge speed of the medicine. The liquid inlet seat is an outward-expanding open shape, which can ensure that the pipeline is filled when the medicine enters, and prevent the small amount of liquid inlet at the liquid inlet from causing air blockage inside, thereby affecting subsequent transportation. The side protrusions can avoid the formation of a tension film at the expansion of the liquid inlet seat, thereby affecting the circulation effect of the medicine.

[0018] 3. The present invention provides a telescopic push rod motor and a telescopic rod. The travel code in the telescopic push rod motor with travel code is used to transmit the telescopic length of the push rod to a controller such as a PLC in real time, and to provide real-time feedback on the immersion level of the connecting seat.

[0019] 4. The present invention provides a transfer liquid storage barrel, a reflux pipe and an automatic liquid level valve. The automatic liquid level valve can automatically close the switch according to the height of the liquid level in the medicine box, thereby maintaining a constant medicine liquid level in the medicine box; the transfer liquid storage barrel can be used to temporarily store the medicine in the medicine adding tube. When the medicine in the barrel reaches a certain amount, it is pressurized by a pressure pump and then transported back to the medicine box for secondary use, thereby avoiding waste of medicine.
