Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a masterbatch storage tank. Background Art

[0002] Masterbatch refers to the pelletized material obtained by first mixing and kneading various required additives, fillers and a small amount of carrier resin for the convenience of operation during the plastic processing and forming process, and then passing through processing processes such as metering, mixing, melting, extrusion, and pelletizing by equipment such as an extruder.

[0003] During the storage process of masterbatch, it is easy to get damp, which will cause the performance of the masterbatch to deteriorate and is not convenient for subsequent processing. In the prior art, the storage tank is generally ventilated by a blower, but due to the relatively large size of the storage tank, the ventilation effect of the blower is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the storage tank is generally ventilated by a blower, but due to the relatively large size of the storage tank, the ventilation effect of the blower is poor, and a masterbatch storage tank is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A masterbatch storage tank includes an inner box body. A discharge port is arranged at the bottom of the inner box body, and the upper part is sealed by a first upper cover. The first upper cover is provided with a feeding port. The periphery of the inner box body is provided with uniformly distributed second air holes. The periphery of the inner box body has at least two independent exhaust cavities respectively communicated with the inside of the inner box body. Each exhaust cavity can exhaust independently, and a blower is connected and installed to the inner box body.

[0007] An outer box body is sleeved outside the inner box body. There is a chamber between the outer box body and the inner box body. The upper part of the chamber is sealed by a second upper cover, and the lower part of the chamber is sealed by a lower cover. A plurality of partition plates are arranged in the chamber. The partition plates are arranged along the axis direction of the inner box body. The plurality of partition plates can divide the chamber into a plurality of exhaust cavities, and the lower cover has an exhaust structure.

[0008] The lower cover is rotatably connected to the inner box body. The lower cover is provided with a first exhaust port, and the exhaust port of the lower cover is sealed by a switch door.

[0009] The lower cover is fixedly connected to the inner box body. The lower cover is provided with second exhaust ports corresponding to and communicated with the exhaust cavities. Each second exhaust port is sealed by a door body that can be opened and closed.

[0010] A wind pipe is installed at the axis position inside the inner box body. The wind pipe has an air flow channel, and a first air hole is formed on the circumferential side of the wind pipe. The top end of the wind pipe penetrates through one end of the first upper cover and is communicated with the fan.

[0011] The air inlet end of the fan is communicated with an air flow heating device, and the air outlet end points to the air flow channel.

[0012] The beneficial effect of a masterbatch storage tank proposed by the present utility model is that the device can not only conduct directional ventilation on the air flow flowing inside the inner box body, but also, since only a certain exhaust cavity is opened each time, compared with the traditional method of ventilating the entire large storage tank at one time, under the condition of the same power of the fan, the device can make the air flow velocity in the masterbatch faster, and the faster flow velocity is more conducive to carrying away the moisture of the masterbatch.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figures 1 - 4 , a masterbatch storage tank includes an inner box body 12. A discharging port 7 is provided at the bottom of the inner box body 12, and the upper part is sealed by a first upper cover 1. The first upper cover 1 is provided with a feeding port 4. Among them, the feeding port 4 and the discharging port 7 are both installed with openable and closable covers or valves. The circumferential side of the inner box body 12 is provided with uniformly distributed second air holes 15. The circumferential side of the inner box body 12 has at least two independent exhaust cavities 11 that are respectively communicated with the inside of the inner box body 12, and each exhaust cavity 11 can exhaust independently. The inner box body 12 is connected and installed with a fan 3.

[0020] When ventilation is required during the process of the device storing masterbatch, air is sent into the inner box body 12 through the fan 3, and the exhaust cavities 11 at different positions are opened respectively for exhaust. Refer to Figure 4 , when a certain exhaust cavity 11 is opened, air flow will be discharged from that exhaust cavity 11. In this way, not only can the air flow passing through the inner box body 12 be directionally ventilated, but also because only one exhaust cavity 11 is opened each time, compared with the traditional way of ventilating the entire large storage tank at one time, under the condition of the same fan power, the device can make the air flow velocity in the masterbatch faster, and the faster flow velocity is more conducive to carrying away the moisture of the masterbatch.

[0021] Refer to Figure 3 , Figure 4 , an outer box body 6 is sleeved outside the inner box body 12, there is a chamber 16 between the outer box body 6 and the inner box body 12, the upper part of the chamber 16 is sealed by a second upper cover 5, the lower part of the chamber 16 is covered by a lower cover 8, and a number of partition plates 13 are arranged in the chamber 16. The partition plates 13 are arranged along the axis direction of the inner box body 12. The multiple partition plates 13 can divide the chamber 16 into multiple exhaust cavities 11. The lower cover 8 has an exhaust structure. By sleeving an outer box body 6 outside the inner box body 12 at intervals, a chamber 16 is formed between the two, and then the chamber 16 is divided into multiple independent exhaust cavities 11 by the partition plates 13. Different exhaust cavities 11 are opened for exhaust through the exhaust structure of the lower cover 8. The structure is simple and convenient for manufacturing.

[0022] As an implementation manner of the exhaust structure, refer to Figure 2 , the lower cover 8 is rotatably connected to the inner box body 12. The lower cover 8 is provided with a first exhaust port, and the exhaust port of the lower cover 8 is sealed by a switch door 9. When exhausting, the switch door 9 is opened, and then the lower cover 8 is rotated. Whichever exhaust cavity 11 the switch door 9 is aligned with, that exhaust cavity 11 will exhaust.

[0023] As another implementation manner of the exhaust structure, the lower cover 8 is fixedly connected to the inner box body 12. The lower cover 8 is provided with second exhaust ports corresponding to and communicating with the exhaust cavities 11 in number, and each second exhaust port is sealed by a door body that can be opened and closed. Opening the door bodies at different positions will open different exhaust cavities 11.

[0024] In order to facilitate better cross-flow of air flow, an air duct 2 is installed at the axis position inside the inner box body 12. The air duct 2 has an air flow channel 10. The first air holes 14 are opened on the circumferential side of the air duct 2. The top end of the air duct 2 penetrates through one end of the first upper cover 1 and is connected to the fan 3. The air flow generated by the fan 3 is led to a deeper part of the inner box body 12 through the air flow channel 10.

[0025] The air inlet end of the fan 3 is connected to an air flow heating device, and the air outlet end points to the air flow channel 10 to increase the temperature of the air flow entering the inner box body 12.

[0026] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes to obtain technical solutions, concepts, and designs, which should all be covered within the protection scope of the present utility model.
