A liquid pipe 2 is provided inside the metering cabinet 1, and a flow meter 3 is installed at the upper end of the liquid pipe 2 through a metering tube 10. Cabinet doors 4 are installed on both sides of the front end of the metering cabinet 1 through hinges. The cabinet doors 4 are used for opening and closing the metering cabinet 1, and the side walls of the metering cabinet 1 are provided with ventilation holes 7. The ventilation holes 7 cooperate with the heat dissipation component 8 for ventilation and heat dissipation inside the metering cabinet 1. The inner wall of the metering cabinet 1 is provided with a wall mounting strip 5, and a mounting bracket 6 is installed on the surface of the wall mounting strip 5 by bolts. The mounting bracket 6 cooperates with the wall mounting strip 5 for installing components such as the liquid pipe 2. A bottom box 9 is provided at the bottom of the metering cabinet 1. The bottom box 9 allows the metering cabinet 1 to be raised to prevent the moisture on the ground from affecting the components inside the cabinet, and the metering cabinet 1 and the bottom box 9 are an integrated structure.

[0023] like Figure 2 As shown, the heat dissipation component 8 for heat dissipation inside the cabinet is arranged at the bottom of the metering cabinet 1, and the heat dissipation component 8 includes a heat dissipation box 801, a ventilation pipe 802, a mounting plate 803, a one-way pipe 804, a filter 805 and a movable plate 806. Ventilation pipes 802 are arranged on both sides of the heat dissipation box 801. The ventilation pipes 802 on both sides of the heat dissipation box 801 are connected to the exhaust fan to draw the outflow of the internal gas of the metering cabinet 1, so that the internal temperature of the metering cabinet 1 is brought outside the cabinet, which plays a role in cooling and removing dust in the cabinet, and the heat dissipation A mounting plate 803 is provided on the top of the heat box 801, and a one-way tube 804 is provided inside the mounting plate 803. The lower end of the one-way tube 804 made of rubber will be closed when the gas flows back to prevent the dust-containing gas from entering the metering cabinet 1, and a filter 805 is provided under the one-way tube 804. The filter 805 plays the role of filtering dust. A movable plate 806 is provided at the front end of the heat dissipation box 801. The movable plate 806 can be removed at the front end of the heat dissipation box 801 for cleaning or replacing the filter 805.

[0024] like Figure 3 As shown, the top of the metering cabinet 1 is provided with an auxiliary component 11 for auxiliary limiting, and the number of auxiliary components 11 is set in two groups. The auxiliary component 11 includes a connecting plate 1101 and an auxiliary ring 1102, and the side of the connecting plate 1101 is installed with an auxiliary ring 1102. The connecting plate 1101 and the auxiliary ring 1102 play an auxiliary limiting role on the rear side of the metering tube 10 passing through the top of the metering cabinet 1. The auxiliary rings 1102 are linearly and equidistantly distributed about the connecting plate 1101, and the shape of the auxiliary rings 1102 is a semicircular ring.

When the metering tube 10 is installed, the connecting plate 1101 and the auxiliary ring 1102 cooperate with the auxiliary splint 1104 to limit the metering tube 10 to avoid the metering tube 10 and the opening on the cabinet from shaking and colliding. During subsequent adjustments, the electric push rod 1103 controls the movement of the auxiliary splint 1104 by telescoping to facilitate the maintenance of the metering tube 10. For protection or replacement, when in use, turn on the exhaust fan connected to the end of the ventilation pipe 802, so that the hot gas inside the metering cabinet 1 is transported from the one-way pipe 804 to the outside of the cabinet through the heat dissipation box 801, so that the internal temperature of the metering cabinet 1 is brought outside the cabinet, which has the effect of cooling and dust removal inside the cabinet. At the same time, the filter 805 plays the role of filtering dust. When the gas flows back, the lower end of the rubber one-way pipe 804 will close to prevent the dust-containing gas from entering the interior of the metering cabinet 1. When cleaning, the movable plate 806 can be removed at the front end of the heat dissipation box 801, and the filter 805 can be pulled out for cleaning or replacement.
