Description

Technical Field

[0001] The invention relates to the field of powder containers, in particular to a powder quantitative discharging tank. Background Art

[0002] Existing tanks only have a single storage function. In daily life, people usually grab some materials by hand or dump the tank to take out materials. The traditional material taking process cannot well control the amount of materials used each time. For users, they hope to ensure that the amount of materials taken each time is constant to improve the user experience. However, existing storage tanks either do not have the function of quantitative material taking or have too complex structures, which brings troubles to users. Summary of the invention

[0003] The purpose of the present invention is to overcome the above disadvantages and provide a powder quantitative discharging tank, which not only has the function of quantitative discharging, but also has a simple structure, reasonable and compact design, and is easy to use.

[0004] The present invention is implemented through the following technical scheme: a powder quantitative discharging tank, characterized in that it comprises a hollow tank body, a partition and a quantitative bin;

[0005] The partition is fixedly arranged in the tank body and divides the inner cavity of the tank body into an upper chamber and a lower chamber, and at least two through holes penetrating the upper chamber and the lower chamber are opened on the partition;

[0006] A discharge pipe is also fixedly arranged in the upper chamber of the tank body, the lower end of the discharge pipe is connected to the upper end of at least one through hole, the discharge pipe extends upward from the lower end and the upper end extends to communicate with the outside of the tank body;

[0007] The through hole connected to the lower end of the discharge pipe is the discharge through hole, and the remaining through holes are the feed through holes;

[0008] The quantitative bin is arranged in the lower chamber of the tank body, and one or more U-shaped channels are arranged inside the quantitative bin, and the two ports of each U-shaped channel can be respectively connected with the lower port of a feed through hole and the lower port of a discharge through hole.

[0009] Its working principle and process are as follows:

[0010] The powder quantitative discharging tank is mainly used to store powdered solid particles, such as shell powder, etc. During use, the discharging tank is placed vertically. When the two ports of the U-shaped channel are in a corresponding communication state with the lower ports of each through hole, the material enters the U-shaped channel through the feed through hole on the partition. Due to the fluidity and gravity of the powdered solid particles, a certain amount of material is retained in the U-shaped channel each time. When the material is reduced, the tank body can be slightly shaken so that the material remains quantitatively in the U-shaped channel. During the dumping of the tank body, the quantitative material retained in the U-shaped channel is poured out through the discharging pipe. The material in the upper chamber moves away from the through hole due to the dumping of the tank body and is separated from the through hole. The powder quantitative discharging tank has the function of quantitative discharging, and the error of the discharge amount each time can be controlled between ±0.2 grams, which meets most usage requirements.

[0011] In order to better implement this plan, the following optimization solutions are also provided:

[0012] In order to facilitate opening and closing of the through holes, the quantitative bin is slidably connected in the lower chamber, and during the movement of the quantitative bin relative to the lower chamber, the two ports of each U-shaped channel of the quantitative bin can be in different states of being simultaneously connected or disconnected with the corresponding feed through holes and discharge through holes.

[0014] The slide plate is slidably connected to the partition through a slide groove arranged at the bottom of the partition plate, so that the slide plate can be in two states during the sliding process: the two ports of the U-shaped channel are connected to the feed through hole and the discharge through hole, or the slide plate blocks the feed through hole and the discharge through hole at the same time.

[0015] In order to facilitate the displacement of the quantitative bin, the quantitative bin further comprises a knob connected to the slide plate or the U-shaped portion and extending out of the lower chamber for facilitating the displacement of the quantitative bin relative to the slide groove.

[0016] Preferably, the bottom of the tank body is provided with a slot extending in the same direction as the slide slot, the knob is arranged at the bottom of the U-shaped portion, and the knob is slidably installed in the slot and can move relative to the slot.

When the two ports of the U-shaped channel 34 are in a corresponding communication state with the lower ports of each through hole, the material c enters the U-shaped channel 34 through the feed through hole 22 on the partition 2. Due to the fluidity and gravity of the powder solid particles, it is determined that the material c is retained in the U-shaped channel 34 each time. A certain amount of material c is retained in the U-shaped channel 34 each time. When the material is reduced, the tank body 1 can be slightly shaken so that the material is quantitatively retained in the U-shaped channel 34. During the dumping of the tank body, the quantitative material d retained in the U-shaped channel is poured out through the discharging pipe 4. The material c in the upper chamber a moves away from the through hole due to the dumping of the tank body 1 and is separated from the through hole. The powder quantitative discharging tank has the function of quantitative discharging, and the error of each discharging amount can be controlled between ±0.2 grams, which meets most of the usage requirements.
