In general, a storage tank for storing polymer fine powder in various granular forms, such as ceramic raw materials, refractory raw materials, skim milk powder, wood powder, iron oxide, grains, and pigments, has a main body 10 as shown in FIG. It is generally provided in a cylindrical shape having a certain height, the upper portion thereof is provided with a supply port 12 for supplying the contents into the storage compartment 11 and at the same time the lower portion to easily guide the contents down by its own weight The guide part 13 of the ordinary light lower narrow was provided, and the discharge port 14 which discharges the content was provided in the lower end of the guide part 13.

Therefore, when the discharge port 14 of the storage tank 10 is opened, the contents stored in the storage chamber 11 are configured to be discharged downwards by the weight of the contents at the same time. In the case of the strong powder, there is a problem in that the vertical hole H is generated as a bridge phenomenon in which only the contents positioned in a vertical line with the outlet 14 are discharged as shown in the drawing.

Such a problem was that the inner periphery of the storage chamber 11, that is, the contents located on the inner circumferential wall side of the storage chamber was not easily discharged to form a residual layer of the granular material, and also the storage chamber 11 There was a problem in that the discharge efficiency is lowered because the contents are not evenly discharged, such as the powders supplied in the inside are not discharged in order.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a powder discharging device capable of continuously discharging any type of powder stored in a storage tank in a constant state.

Another object of the present invention is to provide a powder discharging device capable of preventing the powder from sticking to the inner wall of the storage tank, and has an excellent effect, particularly in the case of a strong powder powder.

This object of the present invention is achieved by providing a discharge structure of the storage tank for temporarily storing and discharging the various granules in the form of granules for a predetermined process, the granule discharge structure is conical guide member, And lowering means and vibration means. The conical guide member allows the powder to be uniformly dispersed in the hopper portion of the storage tank when the powder stored in the storage tank moves downward by its own load. The elevating means is connected to the guide member to elevate the guide member, so that the powders in the storage tank exert mutual force by the elevating movement. Therefore, the granular material can be discharged continuously in a constant state in addition to the downward movement due to its own load, and it can be discharged continuously in a predetermined state, and also prevents the adhesion of the granular material to the inner wall of the storage tank and directly at the discharge part. The bridge phenomenon that occurs can be completely prevented.

In addition, since the vibration means transmits vibrations to the lifting means and the guide member and the storage tank, the vibration means prevents adhesion between the powder particles and the entanglement and the inner wall of the storage tank.

Next, embodiments of the present invention will be described in detail with reference to the drawings. 2 and 3 is a partial cutaway view showing a powder discharging device of the storage tank according to an embodiment of the present invention. 2 shows a case where the elevating device is lifted, and FIG. 3 shows a case where it is lowered. The storage tank 30 is manufactured in various forms, and various granular particles 32 in a granular form are stored in the storage tank. Although not shown, the granular material 32 is supplied by a constant supply port which is connected to the upper proper position of the storage tank 30. The hopper 34 forming the bottom of the storage tank is tapered so that the powder 32 can be easily moved to the outlet 36 by its own load.

The guide member 38 is positioned in the hopper 34. The guide member 38 is moved up and down by a predetermined distance by the elevating means from the upper end and the lower end of the hopper 34. The guide member 38 is formed in a conical shape with a narrow upper portion and a wider lower portion, and the maximum outer diameter of the guide member can be smoothly discharged in a relationship between the inner diameter of the hopper 34 and the inner diameter of the discharge port 36. It is determined to have a furnace.

The lifting means is shown in the drawing is composed of a cylinder 40 and a piston 42 and a compressor (not shown) for driving the lifting means, and the like. There will be. The vibrator 46 is shown to be formed below the cylinder 40 and may be configured by conventional methods. In order to prevent the cylinder 40 and the piston 42 from being damaged by contact with the granular material, a protective member 44 is provided around the elevating means. The protective member 44 is made of a flexible and elastic material, such as synthetic resin or synthetic rubber. In this embodiment, the synthetic rubber is used to form a bellows tube type.

The support 41 supports the cylinder 40 and the protection member 44. Reference numeral 48 denotes a discharge station. The container 47 is for receiving the granules discharged from the discharge port 36 and sending them to another device or storage tank.

Referring to the effect of the present invention is configured as described as follows.

2 and 3, the granular material stored in the storage tank 30 is located in the discharge station 48 is discharged through the discharge port 36, it is discharged to the desired supply side, such as other storage tank connected thereto. . Since the granular material 32 has its own load, it is moved downward toward the discharge port 36 by the load. Although the properties vary depending on the granules, particularly in the case of the granules having strong adhesive force, fine granules, and various chemical substances, the granules adhere to the inner wall of the storage tank 30. The first moves downward. When a certain amount of the granular material is moved downward by its own load, the guide member evenly distributes the granular material into the hopper inner circumference so as to pass through the flow path formed in the relationship between the guide member 40 and the hopper inner diameter and the outlet diameter. Since the granules gathered around the inner wall of the storage tank are heavier in load than those of the central part, they move downward faster than the other parts by the load, and now the amount of the granules in the storage tank is discharged as a whole. Done.

In addition, the guide member 40 is moved up and down by the elevating means, thereby affecting the powder in the storage tank 30 in all directions. In addition, since the guide member is moved up and down by the elevating means, the granules are agitated with each other, and the granules in the storage tank are discharged at a constant speed and quantity because the particles and the particles interact with each other dynamically. Furthermore, the powder adhering to the inner wall of the storage tank can be easily discharged. In addition, the vibrator transmits vibration to the storage tank through the cylinder 40, the protection member 44, the guide member 38, and the like, thereby preventing adhesion between the powders and entanglement and adhesion of the powder to the inner wall of the storage tank. do.

As described above, the powder discharging device according to the present invention is capable of discharging the powder at a constant and uniform speed and amount by synergistically combining the structure of the guide member, the elevating means, and the vibrator.

According to the present invention, the granular material in the storage tank is moved downward at a uniform speed and quantity despite the variety of types and characteristics, so that the discharge amount is improved and the discharge efficiency is improved.

Since the powder is discharged uniformly, there is an advantage of accurately matching the mixing ratio in the next process.

Furthermore, it is possible to fundamentally prevent the phenomenon of the powder adhering to the inner wall of the storage tank.
