Description

Technical Field

[0001] This utility model relates to the field of forage processing, and in particular to a steam explosion device for processing rice straw to produce roughage, which is suitable for straw resource utilization and feed processing production scenarios. Background Technology

[0002] In the process of converting straw into forage, steam explosion treatment technology plays a crucial role. High-intensity explosion treatment breaks down the dense structure of plant fibers, effectively improving the nutritional value, digestibility, and palatability of straw. However, existing steam explosion treatment equipment, especially steam explosion devices used to uniformly introduce steam and ensure uniform material temperature, has many problems. Traditional rice straw treatment devices often suffer from uneven heating due to material accumulation, resulting in poor fiber degradation. This not only affects the quality of straw converted into high-quality roughage but also reduces production efficiency and wastes resources. Therefore, the development of a steam explosion device that ensures stable and uniform steam introduction and uniform material heating is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a steam explosion device for processing rice straw to produce roughage, which effectively solves the problems of uneven heating of materials and poor fiber degradation in traditional devices, and achieves full contact between steam and straw, so that the straw is heated evenly, thereby improving straw processing efficiency and roughage quality.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A steam explosion device for processing rice straw into roughage includes a vertically arranged explosion tank. The explosion tank has a feed inlet at the top with a feed valve, and a discharge outlet at the bottom with a discharge valve. Multiple air inlets are located at the bottom of the explosion tank. Multiple circumferentially distributed spiral guide plates are fixed to the inner wall of the explosion tank, extending from the top to the bottom. Crushed straw is fed into the explosion tank through the feed inlet. The straw slides down the spiral guide plates; some straw slides down to the middle of the spiral guide plates, while some slides to the bottom. The spiral guide plates ensure that the straw is dispersed and piled up with sufficient gaps for steam to pass through, allowing for full contact between the steam and the straw. After feeding, the feed valve is closed, and steam is introduced through the air inlets. Once a certain pressure is reached, the pressure is maintained. After a period of pressure maintenance, the discharge valve is quickly opened to release pressure instantaneously, thereby crushing the straw.

[0006] Preferably, each air inlet is located between two adjacent spiral guide plates.

[0007] Preferably, the number of spiral guide plates is 3-6.

[0008] Preferably, a distributor is provided below the feed inlet, and the distributor is fixedly connected to the blasting tank through multiple connecting rods;

[0009] The distributor is conical in shape.

[0010] Preferably, a steam feed pipe is fixed inside the air inlet, and the steam feed pipe extends into the protruding end of the rupture tank and is formed with multiple radially distributed air outlet holes along the axial direction. An air inlet valve is provided on the steam feed pipe.

[0011] Preferably, the inner end of the steam feed pipe is sealed, which ensures that some gas is ejected from the radial outlet.

[0012] The steam feed pipe is provided with an axial vent hole at the sealing point.

[0013] The outstanding effect of this utility model is:

[0014] Compared with existing technologies, the spiral guide plate design allows straw to slide into the bottom of the tank through the guide plate when it is added, forming sufficient gaps to facilitate the passage of steam and create conditions for full contact between steam and straw.

[0015] The air inlet is located between adjacent spiral guide plates, allowing steam to rise slowly and evenly along the guide plates, ensuring uniform heating of the straw and effectively solving the problem of uneven heating of materials in traditional devices, thus improving the fiber degradation effect.

[0016] The distributor disperses the incoming straw material from the center outwards, allowing the straw to be more evenly distributed and allocated through the spiral guide plate, further enhancing the straw dispersion and accumulation effect and improving the uniformity of steam-straw contact.

[0017] The steam feed pipe and its radial and axial air outlets enable multi-point steam intake and allow the straw to be heated by steam from different directions, thereby improving the uniformity of straw heating, optimizing straw processing, and enhancing the quality of roughage.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] The following is for reference Figures 1 to 3 The present invention will be described as follows: Example

[0027] A steam explosion device for processing rice straw to produce roughage, such as Figure 1 As shown, it includes a vertically arranged blasting tank 10. The blasting tank 10 has an inlet 11 at the top and is equipped with an inlet valve to control the input of straw; an outlet 12 at the bottom and is equipped with an outlet valve to handle instantaneous pressure relief and material discharge after processing; and multiple air inlets 13 at the bottom to provide channels for steam to enter.

[0028] Multiple circumferentially distributed spiral guide plates 20 are fixed to the inner wall of the blasting tank 10, extending from the upper part to the lower part. There are 3 to 6 spiral guide plates 20. Their unique design allows the crushed straw to slide down along the guide plates after being fed into the inlet. Some of the straw slides down in the middle of the guide plates, while some slides to the bottom, thus dispersing and accumulating the straw and creating sufficient gaps for steam to pass through, ensuring full contact between the steam and the straw.

[0029] Each air inlet 13 is located between two adjacent spiral guide plates 20. The high-temperature steam entering can rise and flow along the spiral guide plates to achieve slow and uniform air intake and ensure that the straw is heated evenly. Example

[0030] like Figure 2 , Figure 3 As shown, based on Example 1, a distributor 30 is provided below the feed inlet 11. The distributor 30 is fixedly connected to the blasting tank 10 through multiple connecting rods 31. The distributor 30 is conical in shape, which can disperse the straw material entering from the feed inlet from the center to the outside, so that the straw is dispersed and distributed through the spiral guide plate, further optimizing the dispersion and accumulation effect of the straw.

[0031] A steam feed pipe 40 is fixed inside the air inlet 13. The steam feed pipe 40 extends into the protruding end of the blasting tank 10 and forms multiple radially distributed air outlets 41 along the axial direction, and is equipped with an air inlet valve. After the air inlet valve is opened, steam is dispersed to different positions inside the blasting tank through the multiple radial air outlets, realizing multi-point air intake and significantly improving the heating uniformity of straw in different areas.

[0032] The inner end of the steam feed pipe 40 is sealed to ensure that some gas is ejected from the radial vent. The sealed part is provided with an axial vent 42 so that the straw is heated by steam from different directions, further improving the heating effect.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
