Description

Technical Field

[0001] The utility model relates to the technical field of automatic adding valves, in particular to an automatic adding valve for flotation MB reagent. Background Art

[0002] Flotation reagents are chemicals used in the mineral flotation process to adjust the surface properties of the mineral, increasing or decreasing its floatability. Flotation reagent molecules typically contain hydrophilic and hydrophobic groups, which allow them to adsorb at the water-air interface and reduce the surface tension of the aqueous solution. Flotation reagents are widely used in the flotation of various minerals, such as coal, graphite, sulfur, talc, molybdenite, and other naturally floatable minerals, as well as sulfide minerals such as copper, lead, zinc, and iron. Flotation reagents must be used in conjunction with an addition valve.

[0003] For example, the Chinese patent "A fully automatic flotation reagent quantitative addition system" with announcement number CN221157158U includes a first drug barrel, a second drug barrel and a flotation barrel, the inner walls of the first drug barrel and the second drug barrel are both provided with liquid level detectors; a first liquid extraction pipe is provided inside the first drug barrel, a second liquid extraction pipe is provided inside the second drug barrel, a first three-way valve is fixed on the top of the first liquid extraction pipe and the second liquid extraction pipe, a liquid extraction pump is fixed on the top of the first three-way valve, an electromagnetic flowmeter is connected to the top of the liquid extraction pump, a second three-way valve is provided on the other end of the electromagnetic flowmeter, and the second three-way valve is provided on the other end. A micro-flow regulating valve is provided at the other end of the valve, and a reflux three-way valve is fixed to the bottom of the second three-way valve. The two outlet positions of the reflux three-way valve are respectively fixed with a first discharge pipe and a second discharge pipe. One end of the first discharge pipe extends to the interior of the first medicine barrel, and the other end of the second discharge pipe extends to the interior of the second medicine barrel. A connecting pipe is fixed to the end of the micro-flow regulating valve away from the second three-way valve, and a one-way valve is fixed to the other end of the connecting pipe. The one-way valve is fixed to the side of the flotation barrel. The liquid level detector, the first three-way valve, the liquid pump, the second three-way valve, the reflux three-way valve and the micro-flow regulating valve are all connected to the controller through wires.

[0004] Although the above-mentioned existing technology can realize the use of automatic adding valve, in actual use, on the one hand, when the valve body is used, the reagent is easy to flow into the cylinder. After the reagent contacts the sealing ring on the cylinder, the sealing ring will corrode and fail, causing the reagent to enter the cylinder through the cylinder piston rod, thereby shortening the service life of the cylinder. On the other hand, the valve body is difficult to replace modularly. Usually, when the valve body is partially damaged, the entire valve body structure needs to be replaced, and it is difficult to replace the damaged part alone, which increases the maintenance cost of the valve body. Therefore, it does not meet the existing needs. In this regard, we propose a flotation MB reagent automatic adding valve. Utility Model Content

[0008] Preferably, a first flange is provided at the upper end of the valve body, and the first flange and the valve body are an integrated structure. A second flange is provided at the upper end of the first flange, and second threaded holes are provided at the four corners inside the first flange and the second flange, and the second threaded holes are a through-type structure.

[0009] Preferably, an installation cavity is provided at the center position inside the first flange and the second flange, the installation cavity on the first flange corresponds to the opening position of the installation cavity on the second flange, a sealing ring is fixed inside the installation cavity, and the blocking rod passes through the sealing ring inside the first flange and the second flange.

[0010] Preferably, first threaded holes are provided at the four corners inside the cylinder.

[0011] Preferably, a partition is provided below the interior of the valve body, and a through hole is provided at the center position inside the partition. The through hole is a through-type structure, and the through hole corresponds to the position of the blocking rod.

[0012] Preferably, a medicine main pipe interface is provided at the lower end of the valve body, and a medicine discharge pipe is fixedly provided on the outside of one side of the valve body, and the medicine discharge pipe is communicated with the valve body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can install the cylinder and the valve body in a split manner through the nut and the first thread structure. When assembling the valve body and the cylinder, first align the nut with the upper end of the blocking rod and rotate the nut. The nut moves downward on the blocking rod through the cooperation of the thread and the second thread structure until the upper end of the nut is flush with the upper end of the blocking rod. Then align the telescopic end of the cylinder with the blocking rod and place it on the upper end of the blocking rod. At this time, rotate the nut to move the nut upward until the nut moves between the telescopic end of the cylinder and the blocking rod. At this time, the cylinder and the valve body are fixedly connected by the nut, the first thread structure, and the second thread structure, so as to avoid direct contact between the medicine and the cylinder, thereby extending the service life of the cylinder.

[0015] 2. The utility model uses the first flange and the second flange to enable the valve body to be modularly replaced with a damaged structure. When installing the valve body, the blocking rod is first inserted and fixed on the first flange and the valve body. At this time, the second flange is aligned with the blocking rod and sleeved on the outside of the blocking rod. The second flange is moved downward until the second flange is moved to a suitable position. At the same time, the second threaded hole on the second flange corresponds to the first threaded hole on the first flange. Bolts are then inserted into the second threaded hole and the first threaded hole for fixed installation. The modular installation of the valve body and the flange reduces the maintenance cost of the valve body.

[0016] 3. The utility model can reduce the gap at the connection between the blocking rod and the flange through the installation cavity and the sealing ring. After the first flange and the second flange are installed, the sealing rings at the center of the first flange and the second flange stick to and squeeze each other, thereby reducing the gap at the connection between the first flange and the second flange. At the same time, the sealing ring can reduce the gap at the connection between the blocking rod and the first flange and the second flange, thereby improving the sealing performance of the connection between the blocking rod and the first flange and the second flange.
