Definitions
- a precise metering device A precise metering device
- the utility model relates to a precise metering device.
- the purpose of the present invention is to overcome the above-mentioned shortcomings and provide a precise metering device.
- a precise metering device includes a housing and a rotor; the housing is hollow to form a rotating drum, a feed inlet communicating with the rotating drum is provided above the housing, and a discharging material communicating with the rotating drum is provided below the housing
- the rotor is installed in the rotating drum, and the rotor and the rotating drum form a closed fit to prevent fluid leakage; the rotor is connected to the motor and driven by the motor to rotate in the rotating drum, characterized in that: the outer wall of the rotor corresponds to the inlet and outlet Three measuring grooves are formed; vertical partitions are respectively arranged between the three measuring grooves; horizontal partitions are respectively arranged between adjacent measuring grooves of each measuring groove; and the transverse partitions of the measuring grooves are mutually displaced in the radial direction .
- the upper end of the feed port is in the shape of a trapezoid with a narrow upper and a lower width.
- An acute angle opening is formed on the left side, and an acute angle opening is formed on the right side of the trapezoid and the diaphragm of the rotor and the right side of the diaphragm
- the discharge port is eccentrically set at the climbing position of the drum.
- FIG. 1 is an overall schematic view of the utility model.
- FIG. 2 is a side view of the utility model.
- FIG. 3 is a top view of the utility model.
- FIG. 4 is a bottom view of the utility model.
- FIG. 5 is a schematic diagram of the present invention.
- a precise metering device including a housing 1 and a rotor 2; the housing 1 is hollow to form a rotating drum 11, above the housing 1 is provided with the drum 11 communicating Feed port 12, a discharge port 13 communicating with the rotating drum 11 is provided under the housing 1; the rotor 2 is installed in the rotating drum 11, and the rotor 2 and the rotating drum 11 form an airtight fit to prevent fluid leakage; the rotor 2 is connected to the motor (Not shown in the figure), driven by the motor to rotate in the drum 11.
- the outer wall of the rotor 2 corresponds to the feed port 12 and the discharge port 13 to form three rounds of measuring grooves 21, 22, 23; between the measuring grooves 21 and 22, 22 and 23 are provided with vertical partitions 241, 242;
- the diaphragms 211, 221, 231 are provided between the adjacent metering grooves of each circle of the metering grooves 21, 22, 23; and the diaphragms 21, 221, of the metering grooves 21, 22, 23, 231 are mutually misaligned in the radial direction, so that the three-turn metering grooves 21, 22, and 23 are aligned with the inlet 12 and the outlet 13 respectively; the three-turn metering grooves are aligned with the inlet 12 so that the shear position of the wheel 2 is Staggered, effectively reducing the rotor 2 shear force.
- the upper end of the feed port 12 has a trapezoidal shape with a narrow upper width and a lower width.
- the left side of the partition plate 221 forms an acute-angle opening
- the right side of the trapezoid forms an acute-angle opening with the right side of the horizontal partition plate 231 and the horizontal partition plate 221 of the rotor 2; this causes the feed port 12 to rotate the rotor 2
- the horizontal partition plate 211, 221, 231 are single-point contacts when they meet the feed port 12, avoiding a line contact, which also greatly reduces the shear force of the rotor 2.
- the discharge port 13 is eccentrically set at the climbing position of the rotating drum, so that the metering grooves 21, 22, and 23 discharge during the climbing process, and the discharge speed can be controlled and adjusted according to the rotation speed of the rotor 2.
- the baffles 211, 221, and 231 are mutually misaligned in the radial direction, so that the materials in the metering grooves 21, 22, and 23 flow out of the discharge port 13 in order to achieve the effect of accurate metering.
- the side wall of the housing 1 on the discharge port 13 is provided with blowing holes 212, 222, 2 32 corresponding to the metering grooves 21, 22, and 23 for blowing the material from the metering groove to make the material flow out
- the material port 13 falls to prevent the material from accumulating in the measuring tank and affecting the subsequent accurate measurement.
- the beneficial effects of the present invention are: no need to evacuate while feeding, will not affect the measurement accuracy; with multi-turn measuring groove, and the radial displacement of the transverse diaphragm of the multi-turn measuring groove makes the multi-turn measuring groove
- the materials in the flow out from the discharge port in order to achieve the effect of accurate metering, and also reduce the shear force of the rotor at the feed port; in addition, the upper end of the inlet has a narrow and wide trapezoidal design, which further reduces the rotor
- the shear force makes the material continuously and more uniformly fall into the feed port, providing a prerequisite for the subsequent accurate measurement of the metering device; the design of the air blowing hole avoids the accumulation of material in the metering tank and affects the subsequent accurate measurement.
