Description

Technical Field

[0001] This utility model relates to the field of low-temperature fermentation technology, and more specifically to a low-temperature fermentation device for straw feed. Background Technology

[0002] Straw is an important by-product of agricultural production, with abundant sources and broad application prospects. Traditional straw disposal methods mostly involve burning or discarding, which not only wastes resources but also causes serious environmental pollution. Therefore, after processing, straw feed can serve as a major feed source for ruminants (such as cattle and sheep). Compared with traditional feed, straw feed has advantages such as low cost, wide availability, and rich nutrition. At the same time, the utilization of straw feed can reduce dependence on traditional feed, lower livestock production costs, and improve economic efficiency.

[0003] The shortcomings of existing technology: Since a large amount of gas is produced during the fermentation of straw feed, it is necessary to release the gas to avoid affecting the pressure and temperature balance inside the fermentation tank. Existing fermentation devices usually release the gas directly through pipes. However, if the gas release pipes are not vented, it is easy for external air to enter the fermentation device, affecting the fermentation process. The fermentation device has insufficient sealing performance, which is also not conducive to maintaining the temperature and humidity inside the tank. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a low-temperature fermentation device for straw feed, which solves the problems of insufficient sealing of the existing fermentation device in the background art, which easily leads to the entry of external air into the fermentation device without venting, affecting the fermentation process, and the unstable temperature and humidity inside the tank.

[0005] This utility model provides the following technical solution: a low-temperature fermentation device for straw forage, including a temperature-controlled fermentation tank, one end of which is fixedly connected to a feeding channel, a densification block is fixedly connected to the top center of the temperature-controlled fermentation tank, a mixing component for stirring straw forage is provided in the middle of the inner cavity of the temperature-controlled fermentation tank, a check valve component for preventing air from entering the temperature-controlled fermentation tank is provided in the middle of the densification block, and a sealing cover is provided at the top of the feeding channel;

[0006] The anti-reverse assembly includes an exhaust pipe fixedly connected to the middle of the top of the encryption block. The lower part of the inner cavity of the exhaust pipe is rotatably connected to an anti-reverse plate for preventing external air from entering. An exhaust hole is opened in the middle of the inner cavity of the encryption block, and a limit ring is fixedly connected to the inner cavity of the exhaust hole.

[0007] Preferably, the vent is connected to the inner cavity of the temperature-controlled fermenter, and the vent pipe is connected to the vent.

[0008] Preferably, a sealing ring is fixedly connected to the top end of the limiting ring, and the check plate is located at the top end of the sealing ring.

[0009] Preferably, the mixing assembly includes a rotating rod located at the central axis of the inner cavity of the temperature-controlled fermenter, a U-shaped stirring rod fixedly connected to the outer surface of the rotating rod, and a spiral stirring rod fixedly connected to the top end of the rotating rod.

[0010] Preferably, a motor is fixedly installed at the bottom center of the temperature-controlled fermentation tank, and the output end of the motor passes through the bottom of the temperature-controlled fermentation tank and is fixedly connected to the bottom of the rotating rod.

[0011] Preferably, the other end of the temperature-controlled fermentation tank is provided with a discharge port, one end of which is provided with an electrically controlled flat gate valve for controlling the discharge of the device, and a temperature monitoring instrument for monitoring the temperature during the fermentation process is provided on one side of the inner cavity of the temperature-controlled fermentation tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model prevents external air from entering the inner cavity of the temperature-controlled fermentation tank through the exhaust pipe by incorporating a backflow preventer. Gases generated during straw fermentation in the tank's inner cavity gather at the exhaust port through the arc-shaped top of the fermentation tank and are then discharged through the exhaust pipe. Since the gas flows upwards, the force generated by this flow pushes the backflow preventer plate upwards, allowing the gas to be concentrated and discharged through the exhaust pipe. After discharge, the backflow preventer plate rotates downwards to the position of the limiting ring, which limits its position. A sealing ring is also added to ensure the seal between the backflow preventer plate and the inner cavity of the exhaust pipe, preventing external air from entering the inner cavity of the temperature-controlled fermentation tank through the exhaust pipe during operation and affecting fermentation. This ensures the stability of temperature and humidity within the temperature-controlled fermentation tank.

[0014] 2. This utility model ensures the airtightness of the feeding channel by providing a sealing cover. After the straw to be fermented is added to the inner cavity of the temperature-controlled fermentation tank through the feeding channel, the inlet is sealed by the sealing cover. At the same time, the output of the outlet is controlled by an electrically controlled flat gate valve, which effectively improves the sealing performance of the device. After the straw is added, it is stirred by the mixing component. The combined use of the U-shaped stirring rod and the spiral stirring rod ensures that the straw can be fully mixed with the chemical reagents required for fermentation, ensuring that the straw can be fully fermented.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The low-temperature fermentation device for straw fodder involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a low-temperature fermentation device for straw forage, such as... Figure 1 - Figure 4 As shown, the device includes a temperature-controlled fermentation tank 1. One end of the temperature-controlled fermentation tank 1 is fixedly connected to a feeding channel 3. A density block 2 is fixedly connected to the top center of the temperature-controlled fermentation tank 1. A mixing component 5 for stirring straw and forage is provided in the middle of the inner cavity of the temperature-controlled fermentation tank 1. A check valve component 6 for preventing air from entering the temperature-controlled fermentation tank 1 is provided in the middle of the density block 2. A sealing cover 7 is provided at the top of the feeding channel 3. When the device is in use, the straw to be fermented is added to the inner cavity of the temperature-controlled fermentation tank 1 through the feeding channel 3. After the addition is completed, the inlet is sealed by the sealing cover 7 to ensure the sealing performance of the device. At the same time, the fermentation temperature is adjusted by the temperature control system in the temperature-controlled fermentation tank 1 according to the specific situation of straw fermentation.

[0022] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the anti-reverse component 6 includes an exhaust pipe 61 fixedly connected to the middle of the top of the encryption block 2. The lower part of the inner cavity of the exhaust pipe 61 is rotatably connected to an anti-reverse plate 62 for preventing external air from entering. An exhaust hole 63 is opened in the middle of the inner cavity of the encryption block 2. A limit ring 64 is fixedly connected to the inner cavity of the exhaust hole 63.

[0023] Furthermore, such as Figure 2 and Figure 3As shown, the vent 63 is connected to the inner cavity of the temperature-controlled fermentation tank 1, and the vent pipe 61 is connected to the vent 63. The top of the temperature-controlled fermentation tank 1 is set in an arc shape. The tightness of the connection between the vent pipe 61 and the inner cavity of the temperature-controlled fermentation tank 1 is effectively increased by the encryption block 2.

[0024] Furthermore, such as Figure 3 As shown, a sealing ring 65 is fixedly connected to the top of the limiting ring 64, and a check plate 62 is located at the top of the sealing ring 65. During straw fermentation, a large amount of gas is generated. After the gas is generated, it gathers at the exhaust port 63 through the arc-shaped top of the temperature-controlled fermentation tank 1, then flows upward and is discharged through the exhaust pipe 61. Simultaneously, since the gas flows upward, the force generated by the upward flow pushes the check plate 62 upward, causing the gas to be discharged through the exhaust pipe 61. After fermentation, no more gas is generated, and the check plate 62 rotates downward to the top of the limiting ring 64. The limiting ring 64 limits the position of the check plate 62, and the sealing ring 65 ensures the seal between the check plate 62 and the inner cavity of the exhaust pipe 61, preventing external air from entering the inner cavity of the temperature-controlled fermentation tank 1 through the exhaust pipe 61 during operation and affecting the fermentation process.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the mixing component 5 includes a rotating rod 51 located at the central axis of the inner cavity of the temperature-controlled fermenter 1, a U-shaped stirring rod 52 fixedly connected to the outer surface of the rotating rod 51, and a spiral stirring rod 53 fixedly connected to the top end of the rotating rod 51.

[0026] Furthermore, such as Figure 4 As shown, a motor 54 is fixedly installed at the bottom center of the temperature-controlled fermentation tank 1. The output end of the motor 54 passes through the bottom of the temperature-controlled fermentation tank 1 and is fixedly connected to the bottom of the rotating rod 51. After the straw to be fermented is added into the inner cavity of the temperature-controlled fermentation tank 1, the chemical reagents required for fermentation are added. Then, the motor 54 is started, which drives the rotating rod 51 to rotate, thereby driving the U-shaped stirring rod 52 and the spiral stirring rod 53 to rotate, stirring and mixing the straw and chemical reagents. Through the combined use of the U-shaped stirring rod 52 and the spiral stirring rod 53, the straw can be fully mixed, effectively improving the production efficiency of the device.

[0027] Furthermore, such as Figure 1 and Figure 4As shown, the other end of the temperature-controlled fermentation tank 1 is provided with a discharge port 4. One end of the discharge port 4 is equipped with an electrically controlled flat gate valve 8 for controlling the discharge of the device. Both the input and output ports of the device are equipped with a sealed structure to prevent external air from entering the device and affecting the fermentation process, thus effectively improving the sealing performance of the device. A temperature monitoring instrument 9 is provided on one side of the inner cavity of the temperature-controlled fermentation tank 1 to monitor the temperature during the fermentation process. The temperature monitoring instrument 9 detects the temperature of the inner cavity of the temperature-controlled fermentation tank 1 during the fermentation process. According to the temperature change, the temperature is adjusted by the temperature control system in the temperature-controlled fermentation tank 1 to ensure the stability of the temperature and humidity inside the temperature-controlled fermentation tank 1.

[0028] The working principle of this invention is as follows: First, the straw to be fermented is added into the inner cavity of the temperature-controlled fermentation tank 1 through the feeding channel 3. Then, the corresponding chemical reagents are added according to the fermentation requirements. After the addition is completed, the inlet of the feeding channel 3 is sealed by the sealing cover 7. At the same time, the check plate 62 is located at the top of the limiting ring 64 when there is no gas flow, so that the inner cavity of the exhaust pipe 61 is sealed. Then, the motor 54 is started, which drives the rotating rod 51 to rotate, thereby driving the U-shaped stirring rod 52 and the spiral stirring rod 53 to rotate, stirring and mixing the straw and chemical reagents, ensuring that the straw and chemical reagents are fully mixed and fermentation reaction occurs, effectively improving the production efficiency of the device. Then, the fermentation temperature is adjusted by the temperature control system inside the temperature-controlled fermentation tank 1, so that the straw and chemical reagents undergo low-temperature fermentation in the inner cavity of the temperature-controlled fermentation tank 1. At the same time, the temperature monitoring instrument 9 detects the temperature of the inner cavity of the temperature-controlled fermentation tank 1 during the fermentation process, and adjusts the temperature accordingly. The temperature changes are adjusted by the temperature control system in the temperature-controlled fermentation tank 1 to ensure the stability of the temperature and humidity inside the fermentation tank 1. During fermentation, a large amount of gas is continuously generated. After the gas is generated, it flows upward and gathers at the exhaust port 63 through the arc-shaped top of the temperature-controlled fermentation tank 1. The force generated by the gas flow pushes the check plate 62 to rotate upward, so that the gas is discharged in a concentrated manner through the exhaust pipe 61. After fermentation is completed, no more gas is generated, and the check plate 62 loses its thrust and rotates downward to the top of the limiting ring 64. The limiting ring 64 limits the position of the check plate 62. At the same time, a sealing ring 65 is added to ensure the sealing between the check plate 62 and the inner cavity of the exhaust pipe 61, so as to prevent external air from entering the inner cavity of the temperature-controlled fermentation tank 1 through the exhaust pipe 61 during the use of the device, which would affect the fermentation process. After fermentation, the straw is discharged in a concentrated manner through the discharge port 4. The discharge port 4 is controlled by the electric flat gate valve 8 to ensure the sealing performance of the device.
