Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of moisture-proof storage, and more particularly to a moisture-proof storage device for dry powdered plaster. Background Art
[0002] Plaster is a mixed powder made of carbonate particles or biological debris. It can be mixed into aggregates to improve material strength, or mixed into pigments as a coloring material. It is widely used in the construction of building structures. Plaster is usually in a dry powder state and is prone to caking after being damp, affecting its use. Therefore, it needs to be stored in a suitable storage device.
[0003] Most common storage devices have a simple structure, which only provides a closed box body to load the dry mortar powder for storage and protection, and then puts a desiccant in the material to provide moisture-proof treatment. This storage device has a relatively simple structure. When storing and taking out materials, it is necessary to open the cover on the box body. After the cover is opened, the storage space will be in contact with the outside environment, allowing fresh air from the outside to flow into the storage space. In actual use, sometimes it is not necessary to use all the stored materials, and only part of them can be taken out. After the materials are taken out, the fresh air flowing into the interior contains moisture, which will affect the stored dry mortar powder. Moreover, the dry The drying effect of the desiccant is limited. If the humidity in the air is high, it is easy to cause the internal materials to get damp, affecting the storage quality. In addition, in order to ensure the moisture-proof effect, the desiccant needs to be replaced in time. In order to reduce the impact on the stored materials when replacing the desiccant, many storage structures will separate the desiccant placement space from the material storage space, and then ensure the desiccant's operation through a breathable structure. In order to facilitate replacement, the existing desiccant placement structure is mostly set around the storage space, so that the desiccant only contacts the material on the outside during operation, while the material on the inside is extended, and moisture is not easily absorbed. This type of structure has a poor moisture-proof effect. Utility Model Content

[0032] In this embodiment, the storage chamber 2 in the storage box 1 is used as a space to store dry plaster powder. When the plaster needs to be taken out, the first closing plate 5 is controlled to move to open the connecting port 4 and connect the storage chamber 2 with the discharge chamber 3. The dust dry powder in the storage chamber 2 will enter the discharge chamber 3 under gravity. After a certain amount of plaster dry powder is filled in the discharge chamber 3, the first closing plate 5 is controlled to move to block the connecting port 4 to separate the discharge chamber 3 from the storage chamber 2. Then, the second closing plate 7 is controlled to move to open the discharge port 6 and take out the plaster material in the discharge chamber 3. Then, the second closing plate 7 is controlled to block the discharge port 6.

Under the protection of the ventilation hood 20, the drying box 17 is connected to the interior of the storage chamber 2, and the moisture in the storage chamber 2 is absorbed by the desiccant. The desiccant in the first insertion box 18 absorbs moisture at the outer end of the storage chamber 2, while the desiccant in the second insertion box 19 absorbs moisture from the inner side of the storage chamber 2, thereby providing a drying effect at both the inner and outer ends of the plaster dry powder, thereby increasing the treatment effect of the internal moisture.

[0039] Specifically, when taking out the dry powder material of plaster from the discharge chamber 3, the push rod 24 is controlled to move, so that the push rod 24 slides along the air outlet box, and a thrust is applied to move the push plate 23 toward the discharge port 6, so that all the materials in the discharge chamber 3 are pushed out. After the materials are pushed out, the push plate 23 will block the discharge port 6 to prevent the outside air or foreign matter from pouring in. After closing the second closing plate 7, the push rod 24 is controlled to reset the push plate 23.
[0040] See also Figure 1-Figure 4 As a further embodiment of the storage box: a sealing ring 25 is provided at the connection between the first closing plate 5, the second closing plate 7 and the push rod 24 and the storage box 1.
[0041] Specifically, the sealing effect provided by the sealing ring 25 enables the moving structure of the first closing plate 5, the second closing plate 7 and the push rod 24 to ensure a sealing effect and avoid air leakage.

The sealing cover 26 is opened to load the plaster dry powder to be stored into the storage chamber 2, and then the sealing cover 26 is closed and matched with the storage box 1 by tightening the bolts 28. The tightening bolts 28 are rotated so that the tightening bolts 28 press the sealing cover 26 tightly, so that the sealing cover 26 is tightly attached to the storage box 1 through the sealing gasket 27 to maintain the sealing effect.

[0046] See also Figure 1-Figure 4 As a further embodiment of the storage box: sliding grooves 31 are opened at both ends of the storage box 1, and a sealing plate 32 is slidingly connected in the sliding groove 31, and the sealing plate 32 cooperates with the air inlet cavity 8 and the air outlet 12.
[0047] Specifically, when it is not necessary to introduce hot air into the storage chamber 2 for drying, the air inlet chamber 8 and the air outlet 12 are blocked from the outside.
[0048] In summary, when the overall device is in use (or running):
[0049] When the equipment is used to store dry powdered plaster, the upper sealing cover 26 is opened to expose the storage chamber 2, and the plaster dry powder is filled into the storage chamber 2, and then the sealing cover 26 is closed and matched with the storage box 1 by tightening the bolts 28. The tightening bolts 28 are rotated so that the tightening bolts 28 press the sealing cover 26 tightly, so that the sealing cover 26 is tightly attached to the storage box 1 through the sealing gasket 27 to maintain the sealing effect, and the storage chamber 2 in the storage box 1 is used as a space to store the plaster dry powder. When the plaster needs to be taken out, the first closing plate 5 is controlled to move to open the connecting port 4 to connect the storage chamber 2 with the discharge chamber 3. The dust dry powder in the storage chamber 2 will enter the discharge chamber 3 under gravity. After a certain amount of plaster dry powder is filled in the discharge chamber 3, the first closing plate 5 is controlled to move to block the connecting port 4 so that the discharge chamber 3 and the storage chamber 2 are connected. 2 is separated, and then the second closing plate 7 is controlled to move to open the discharge port 6. By controlling the movement of the push rod 24, the push rod 24 slides along the air outlet box, and a thrust is applied to move the push plate 23 toward the discharge port 6, pushing out all the materials in the discharge chamber 3, thereby taking out the plaster material. After the materials are pushed out, the push plate 23 will block the discharge port 6 to prevent the outside air or foreign matter from pouring in. Then the second closing plate 7 is controlled to block the discharge port 6, and the push rod 24 is controlled to reset the push plate 23. During the material taking process, the plaster material in the storage chamber 2 will not come into contact with the external environment, thereby preventing the space in the storage chamber 2 from being affected by the outside world. In addition, the sealing effect provided by the sealing ring 25 enables the moving structure of the first closing plate 5, the second closing plate 7 and the push rod 24 to ensure the sealing effect and avoid air leakage.
[0050] When storing the plaster dry powder, the content and state of the plaster dry powder in the storage chamber 2 can be observed through the sealing glass 30 and the observation port 29, which is convenient for adding new materials and judging the storage state. If it is necessary to dry the inside of the storage chamber 2, for example, when filling new materials and opening the sealing cover 26 to cause fresh air to flow in, the fan 9 and the heater 10 are started, and the fan 9 generates negative pressure to allow the external gas to flow into the air inlet chamber 8, and the heater 10 will play a drying and heating role, heating the incoming air to make the air dry, and then allowing the dry hot air flow to flow into the storage chamber 2 from the air inlet 11, drying the storage environment and keeping the storage environment dry, and then allowing the internal air flow to flow out from the air outlet 12. During this period, the filter 13 will protect the air inlet chamber 8, the air inlet 11 and the air outlet 12, on the one hand to prevent external dust from entering the storage chamber 2 with the air flow to contaminate the plaster material, and on the other hand to prevent the plaster dry powder in the storage chamber 2 from leaving the storage device, without the need to pass hot air into the storage chamber 2. During drying, the air inlet chamber 8 and the air outlet 12 are blocked from the outside. In addition, in addition to heating and drying, moisture in the storage chamber 2 is absorbed by the desiccant. A sufficient amount of desiccant is filled in the drying box 17. The first insertion box 18 of the drying box 17 is located in the first insertion slot 15, and the second insertion box 19 is located in the second insertion slot 16. It is located inside the drying column 14 and is protected by the ventilation hood 20. The drying box 17 is connected to the interior of the storage chamber 2 and absorbs moisture in the storage chamber 2 through the desiccant. The desiccant in the first insertion box 18 absorbs moisture at the outer end of the storage chamber 2, while the desiccant in the second insertion box 19 absorbs moisture from the inner side of the storage chamber 2, thereby providing a drying effect at both the inner and outer ends of the plaster dry powder, thereby increasing the treatment effect of internal moisture. In addition, when installing the drying box 17, the sealing ring 21 is inserted into the sealing groove 22, so that the sealing ring 21 cooperates with the sealing groove 22 to form a sealing effect, thereby ensuring the stable communication between the drying box 17 and the storage chamber 2.
