Description

Technical Field

[0001] This utility model relates to the field of areca nut processing technology, and in particular to a gas-exploded areca nut puffing machine that facilitates unloading. Background Technology

[0002] Chinese Patent CN 221449844 U discloses a steam-exploded betel nut puffing machine. Although it solves the problems of uneven steam input and unsmooth high-pressure steam discharge during depressurization in the past design, the entire inner barrel needs to be removed from the tank and the betel nuts in the inner barrel need to be poured out during unloading. Therefore, the problem of inconvenient unloading still exists. Utility Model Content

[0003] The purpose of this invention is to provide a gas-exploded areca nut extruder that facilitates unloading, thereby solving the problem of inconvenient unloading.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a steam-exploded areca nut puffing machine for easy unloading, comprising a steam explosion tank and a steam generator. The steam explosion tank includes an upper tank and a lower tank. The bottom of the upper tank is provided with a pressure relief hole connecting to the lower tank. A hydraulic cylinder is provided inside the lower tank. A pressure relief plate is connected to the top of the piston rod of the hydraulic cylinder. The pressure relief plate can block or open the pressure relief hole under the action of the piston rod of the hydraulic cylinder. The lower tank is connected to the external atmosphere. The top of the upper tank is provided with... The upper tank has an inlet and an outlet at an angle to the bottom of its side wall. An explosion chamber is located inside the upper tank, with its bottom angled and connected to the outlet. Both the inlet and outlet are equipped with sealing caps. A gap exists between the wall of the explosion chamber and the inner wall of the upper tank. Ventilation holes are evenly distributed on the wall and bottom of the explosion chamber. A steam input pipe is located at the bottom of the upper tank, connected to a steam generator for inputting high-pressure steam into the upper tank.

[0005] Preferably, a horizontal pipe is fixed horizontally inside the gas explosion chamber, and a vertical pipe is fixed vertically on the horizontal pipe. Ventilation holes are evenly distributed on the walls of both the horizontal and vertical pipes.

[0006] More preferably, a main exhaust pipe is connected to the left side of the lower tank, and a butterfly valve is provided on the main exhaust pipe and a muffler is provided at the end of the main exhaust pipe.

[0007] More preferably, a manhole for maintenance is provided on the front side of the lower tank.

[0008] More preferably, the lower tank is placed horizontally on the ground, and the upper tank is fixedly installed on top of the lower tank and supported by the lower tank.

[0009] More preferably, the upper tank is also equipped with a safety valve and a pressure gauge.

[0010] Compared with existing technologies, the advantages of this invention are as follows: By setting an inlet at the top of the upper tank and an outlet at an angle at the bottom of the side wall of the upper tank, and by making the bottom of the internal steam explosion chamber inclined and directly connected to the outlet, the areca nuts can be quickly unloaded directly through the outlet after steam explosion without removing the inner tank, greatly simplifying the unloading operation and improving production efficiency. Furthermore, the walls and bottom of the steam explosion chamber are evenly covered with vents, and a steam input pipe is installed at the bottom of the upper tank, allowing high-pressure steam to permeate evenly into the steam explosion chamber, ensuring uniform heating and consistent puffing of the areca nuts. This solves the problem of inconvenient unloading while maintaining good steam explosion quality. Attached Figure Description

[0015] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0016] It should be noted in advance that, in this utility model, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, in this utility model, unless otherwise explicitly specified and limited, "on" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0017] like Figure 1 and Figure 2As shown, the steam-exploded areca nut puffing machine, which facilitates unloading, includes a steam explosion tank and a steam generator. The steam explosion tank includes an upper tank 1 and a lower tank 2. The bottom of the upper tank 1 is provided with a pressure relief hole 3 that connects to the lower tank 2. A hydraulic cylinder 4 is provided inside the lower tank 2. The top of the piston rod of the hydraulic cylinder 4 is connected to a pressure relief plate 5. The pressure relief plate 5 can block or open the pressure relief hole 3 under the action of the piston rod of the hydraulic cylinder 4. The lower tank 2 is connected to the external atmosphere. Wherein:

[0018] The upper tank 1 is provided with a feed inlet 6 at the top and a discharge outlet 7 at the bottom of the side wall of the upper tank 1. The upper tank 1 is provided with a gas explosion chamber 8 inside. The bottom of the gas explosion chamber 8 is inclined and connected to the discharge outlet 7. Both the feed inlet 6 and the discharge outlet 7 are provided with sealing caps 13.

[0019] A gap is provided between the wall of the steam explosion chamber 8 and the inner wall of the upper tank 1. Ventilation holes are evenly distributed on the wall and bottom of the steam explosion chamber 8. A steam input pipe 9 is provided at the bottom of the upper tank 1. The steam input pipe 9 is connected to a steam generator to input high-pressure steam into the upper tank 1.

[0020] In the above structure, a horizontal pipe 8a is fixed horizontally inside the steam explosion chamber 8, and a vertical pipe 8b is fixed vertically on the horizontal pipe 8a. Ventilation holes are evenly distributed on the walls of both the horizontal pipe 8a and the vertical pipe 8b. The horizontal pipe 8a and the vertical pipe 8b form a three-dimensional steam permeation network within the steam explosion chamber 8, allowing high-pressure steam to penetrate the areca nut material more evenly from multiple directions from the middle and bottom of the chamber, effectively eliminating steam dead zones and significantly improving the uniformity and efficiency of puffing.

[0021] A main exhaust pipe 10 is connected to the left side of the lower tank 2. A butterfly valve 11 is installed on the main exhaust pipe 10, and a silencer 12 is also installed at the end of the main exhaust pipe 10. By setting the main exhaust pipe 10 with the butterfly valve 11, the depressurization steam discharge process can be actively and controllably managed. It can also work with the silencer 12 to ensure that the high-pressure steam is quickly and smoothly discharged from the lower tank while effectively reducing the huge noise generated by depressurization and improving the working environment.

[0022] In this embodiment, a manhole 14 for maintenance is also provided on the front side of the lower tank 2. When not under maintenance, the manhole 14 is sealed by a cover.

[0023] In addition, the lower tank 2 is placed horizontally on the ground, and the upper tank 1 is fixedly installed on top of the lower tank 2 and supported by the lower tank 2, forming a stable integrated support structure. This significantly reduces the overall center of gravity and height of the equipment, enhances the stability and safety of the equipment operation, and saves installation space.

[0024] In addition, the upper tank 1 is also equipped with a safety valve and a pressure gauge (not shown in the attached diagram).

[0025] For the specific structure of the sealing cover 13 of the discharge port 7 in this embodiment, the opening mechanism in CN 221449844 U can be referenced, and the existing structure can be directly adopted. Those skilled in the art can adjust the installation angle of the opening mechanism according to the angle of the discharge port 7. As for the specific structure of the sealing cover 13 of the inlet 6 in this embodiment, a simple conventional sealing cover structure can be directly adopted. Alternatively, both sealing covers 13 can adopt the aforementioned opening mechanism or conventional sealing cover structure. Since the improvement point of this application is not in the structure of the sealing cover 13, it will not be described in detail. Those skilled in the art can use any form of sealing cover 13 without affecting the effect of this application in facilitating material unloading.

[0026] The working process of the gas-exploded areca nut extruder provided by the above-described embodiment, which facilitates unloading, is as follows:

[0027] First, feeding is performed: Open the sealing cover 13 of the feed inlet 6, and add the areca nut raw material to be expanded into the gas explosion chamber 8 inside the upper tank 1 through the feed inlet 6, then close the sealing cover 13 of the feed inlet 6. It should be noted that after feeding, some areca nuts will accumulate at the discharge outlet 7, but this does not affect the expansion process of these areca nuts, because they are still within the interior of the upper tank 1, and the pressure inside the upper tank 1 is uniform.

[0028] Next, the steam explosion process is performed: the steam generator is started, and high-pressure steam enters the upper tank 1 through the steam input pipe 9. The steam passes through the vents on the walls and bottom of the steam explosion chamber 8, evenly filling the entire chamber and heating and pressurizing the areca nuts. During this process, the piston rod of the hydraulic cylinder 4 is in the raised position, driving the pressure relief plate 5 to tightly seal and block the pressure relief hole 3, thus maintaining the high-pressure environment inside the steam explosion chamber 8. When the pressure reaches the set value and is maintained for a certain period of time, the softening process of the areca nuts is completed.

[0029] Then, instantaneous pressure relief is performed: After the steam explosion treatment is completed, the piston rod of the control cylinder 4 retracts rapidly, causing the pressure relief plate 5 to move downwards quickly, instantly opening the pressure relief hole 3. The high-pressure steam in the steam explosion chamber 8 rushes into the lower tank 2 through the pressure relief hole 3. Due to the sudden drop in pressure, the internal structure of the areca nut "explodes" and expands. The steam rushing into the lower tank 2 is finally discharged into the atmosphere through the main exhaust pipe 10.

[0030] Finally, unloading is performed: After the internal pressure of the equipment is completely released, open the sealing cover 13 of the discharge port 7. Because the bottom of the explosion chamber 8 is designed to be inclined and directly connected to the discharge port 7, the expanded areca nuts can automatically and smoothly slide out of the discharge port 7 along the inclined surface under the action of gravity, completing the unloading. The entire process does not require removing any inner liner or basket, making the operation simple and convenient, and effectively solving the problem of inconvenient unloading in the existing technology.

[0031] To facilitate understanding by those skilled in the art of the improvements of this utility model compared to the prior art, some of the accompanying drawings and descriptions of this utility model have been simplified. The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
