[0002] The shortage of forage resources has hampered the sustainable development of animal husbandry. my country, meanwhile, boasts a high straw production. Converting crop straw into high-quality feed not only effectively addresses the environmental pollution caused by open-air straw burning but also provides a rich feed resource for the livestock industry, achieving a win-win situation with both economic and ecological benefits. Steam explosion is a promising pre-treatment technology for converting straw into feed. Steam explosion heats and pressurizes the straw, releasing pressure suddenly, softening and enhancing its flavor, increasing palatability, boosting feed intake, improving digestibility, and ultimately increasing straw feed conversion efficiency.

DETAILED DESCRIPTION
[0018] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a quick-compression pressure-releasing quick-opening valve of the present invention in conjunction with the accompanying drawings.
[0019] like Figure 1 、 2 As shown, a fast-pressing pressure-releasing quick-opening valve includes a fixed flange 1, an equipment discharge port 2, a switch control mechanism 3, a bow-shaped rotating seat 4, and a pressing valve cover mechanism 5. The overall size of the valve can be changed according to the needs of the equipment used.
[0020] The bow-shaped rotating seat 4 is provided with a base 403, and a rotating arm 404 and a fixed arm 402 are provided at both ends of the base 403. The end of the rotating arm 404 is rotatably installed with a fixed flange 1 through a pin shaft 405. The fixed flange 1 is fixedly installed at the lower end of the equipment discharge port 2, and the upper end of the equipment discharge port 2 is connected to the use equipment. A switch pin shaft limiting groove 401 is provided at the end of the fixed arm 402, and a pin hole 101 is provided at the end of the fixed flange 1 close to the fixed arm 402. A motor support plate 301 is provided on one side of the fixed flange 1, and a motor support plate 2 302 is fixedly installed on one side of the motor support plate 1 301. The stepper motor 304 is fixedly installed on the motor support plate 2 302 by bolts. The output shaft of the stepper motor 304 is fixedly installed with a switch pin shaft 303, and the switch pin shaft 303 passes through the pin hole 101. The stepper motor 304 can be controlled to rotate the output shaft of the stepper motor 304, and the switch pin shaft 303 can be controlled to rotate in the pin hole 101 and the switch pin shaft limiting groove 401, so that the fixed arm 402 is hinged or separated from the fixed flange 1, thereby controlling the position of the valve cover mechanism 5 to realize the opening and closing of the valve.
[0021] A pair of clamping handle support ears 501 are provided at the bottom of the base 403, and an elliptical hole is provided in the middle of the base 403. The circular hole at one end of the clamping handle 504 is rotatably connected to the clamping handle support ear 501 through pin shaft three 505, and the other end of the clamping handle 501 is rotatably connected to one end of the clamping handle connecting plate 503 through pin shaft four 506, and the other end of the clamping handle connecting plate 503 is rotatably connected to the bottom of the clamping shaft 507 through pin shaft two 502, and the clamping shaft 507 passes through the elliptical hole of the base 403.
[0022] The compression force spring 508 is sleeved on the compression shaft 507, and the lower end of the compression force spring 508 is connected to the lower shoulder of the compression shaft 507. The compression shaft positioning sleeve 509 is sleeved on the upper part of the compression shaft 507, and the lower end of the compression shaft positioning sleeve 509 is connected to the upper end of the compression force spring 508.

[0023] The upper end of the compression shaft 507 is screwed to the compression shaft gland 512, the upper end of the compression shaft positioning sleeve 509 is bolted to the valve cover 510, and the upper end of the valve cover 510 is bolted to the high-temperature resistant sealing gasket 511. When the compression shaft 507 moves downward, the lower end surface of the compression shaft gland 512 presses against the upper end surface of the compression shaft positioning sleeve, driving the valve cover 510 to move downward. When the compression shaft 507 moves upward, the upper end surface of the compression shaft gland 512 presses against the lower end surface of the compression valve cover, driving the valve cover 510 to move upward.
[0024] How it works
[0025] During the steam explosion process, the quick opening valve is closed Figure 2 When the pressure is released, the output shaft of the stepping motor 304 rotates 90° clockwise through the external control power supply, driving the switch pin 303 to rotate 90° clockwise. Figure 4 As shown, the switch pin 303 is Figure 4 -①Hinged state, rotate to Figure 4 -② Separation state, at this time the switch pin 303 loses the limit control of the fixed arm 401. Figure 5 As shown, the internal pressure of the device pushes the valve cover 510 in the direction of the arrow, causing the valve cover mechanism 5 and the bow-shaped rotating seat 4 to rotate clockwise around the pin 405 driven by the rotating arm 404. The valve pops open instantly, completing the steam explosion.
[0026] When the quick opening valve is open Figure 5 State, when closing the quick-opening valve, push the bow-shaped rotating seat 4, so that the switch pin limit groove 401 is inserted into the switch pin 303, and the output shaft of the stepping motor 304 is controlled to rotate 90° clockwise, driving the switch control pin 303 to rotate 90° clockwise. At this time, the switch pin 303 is Figure 4 -② Separated state, turn to Figure 4 -①Hinged state, the bow-shaped rotating seat 4 is fixed. At this time, the quick opening valve is in Figure 3 In the state shown, the clamping handle 504 is pressed in the clockwise direction, and the clamping handle 504 is rotated to drive the clamping handle connecting piece 503 to move upward through the pin shaft 4 506. The clamping handle connecting piece 503 drives the clamping shaft 507 to move upward through the pin shaft 2 502. The clamping shaft pressure cover 512 presses the valve cover 510 to move upward, and the high-temperature resistant sealing gasket 6 fits with the bottom surface of the fixed flange 1. When the clamping shaft 507 moves upward, the clamping force spring 508 is compressed, and the valve is completely sealed and closed.
[0027] The above process is the opening and closing process of a fast-pressing pressure-releasing quick-opening valve of the present invention.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
