Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a feed fermentation device convenient for temperature control. Background Technique

[0002] A temperature-controllable feed fermentation device is a device used for feed fermentation, usually used in animal husbandry and aquaculture. This device can control the fermentation temperature and humidity, thereby promoting the growth and reproduction of beneficial microorganisms in the feed, improving the nutritional value and taste of the feed, facilitating the digestion and absorption of nutrients by animals. Through various fermentation methods, including static fermentation, dynamic fermentation, and continuous fermentation, etc., fermentation selection can be carried out for different feed types and production requirements.

[0003] For example, in the utility model patent with the publication number CN218202841U, this scheme heats the fermentation tank uniformly by setting a heating wire and filling liquid water in the heating cavity, and the heated steam enters the spray head through the air guide port, annular groove, and annular part and is sprayed out to wet and heat the feed, avoiding the extension of the fermentation time caused by the feed being too dry; by setting a fixed ring and a limiting ring to cooperate with the upper cover to fix the annular part, the fixed ring and the annular part can be taken out for cleaning and replacement by removing the upper cover, improving the replacement efficiency.

[0004] During the fermentation process, microorganisms will release a large amount of gas and increase the internal temperature. Excessive internal temperature and pressure may cause damage to the device, posing a safety hazard. Moreover, excessive temperature and pressure may cause abnormalities in the feed during fermentation, such as excessive decay and deterioration, etc., thus affecting the quality and nutritional value of the feed. However, this scheme cannot adjust the internal temperature and pressure, cannot guarantee the fermentation effect of the feed, and results in a reduction in feed quality.

[0034] The present utility model provides a feed fermentation device convenient for temperature control, including:

[0035] Fermenter 1;

[0036] Sealing cover 2, arranged on the upper end face of the fermenter 1 for sealing the fermenter 1;

[0037] The sealing cover 2 is connected to the fermenter 1 by bolts, which can seal the fermenter 1. At the same time, when the staff removes the bolts, the sealing cover 2 can be separated from the fermenter 1, which is convenient for adding the feed to be fermented into the fermenter 1. At the same time, the lower wall of the fermenter 1 is fixedly communicated with a discharge pipe, through which the feed in the fermenter 1 can be discharged. At the same time, a valve is fixedly installed on the discharge pipe, which can close or open the discharge pipe;

[0038] Annular cavity 3, formed inside the side wall of the fermenter 1;

[0039] Electric heating wire 4, wound and installed in the annular cavity 3;

[0040] The electric heating wire 4 is electrically connected to an external power supply device, which can provide electric energy to the electric heating wire 4 to heat the electric heating wire 4 and heat the feed in the fermenter 1;

[0041] The temperature sensor 5 is arranged on the lower end face of the sealing cover 2;

[0042] The temperature sensor 5 is fixedly installed on the lower end face of the sealing cover 2, and can detect the temperature inside the fermentation tank 1;

[0043] The controller 6 is arranged on the upper end face of the sealing cover 2, and is electrically connected to the electric heating wire 4 and the temperature sensor 5 respectively;

[0044] The controller 6 is fixedly installed on the upper end face of the sealing cover 2. At the same time, it can adjust the heating temperature of the electric heating wire 4. At the same time, the temperature detected by the temperature sensor 5 will be transmitted to the controller 6 in the form of an electric signal for display, which is convenient for the staff to adjust the temperature inside the fermentation tank 1;

[0045] The rotating shaft 7 is rotatably installed on the lower end face of the sealing cover 2;

[0046] A motor is fixedly installed on the upper end face of the sealing cover 2, and the output end of the motor is fixedly connected to one end of the rotating shaft 7, which can drive it to rotate;

[0047] The stirring rod 8 is fixedly installed on the outer surface of the rotating shaft 7;

[0048] The number of the stirring rods 8 is multiple. When the rotating shaft 7 rotates, it can drive the multiple stirring rods 8 to rotate, and can stir the feed inside the fermentation tank 1 to improve the fermentation efficiency;

[0049] The pressure relief mechanism is arranged on the sealing cover 2 and is used for relieving the pressure inside the fermentation tank 1.

[0050] Specifically, the pressure relief mechanism includes;

[0051] The housing 9 is fixedly installed on the upper end face of the sealing cover 2;

[0052] The through hole 10 is formed in the sealing cover 2 and is communicated with the housing 9;

[0053] The through port 11 is formed in the side wall of the housing 9;

[0054] The rubber sleeve 12 is arranged on the upper end face of the sealing cover 2 and is communicated with the through hole 10;

[0055] The driving plate 13 is arranged inside the housing 9;

[0056] The sphere 14 is fixedly installed on the lower end face of the driving plate 13, and the outer surface is in contact with one end of the rubber sleeve 12;

[0057] One end of the compression spring 15 is fixedly connected to the upper inner end face of the housing 9, and the other end is fixedly connected to the upper end face of the driving plate 13;

[0058] When the pressure in the fermentation tank 1 is too high, the gas inside it can enter the through hole 10 and exert an upward force on the sphere 14, causing the drive plate 13 to move upward and compressing the compression spring 15 at the same time. At this time, the gas flowing out of the through hole 10 can be discharged to the outside through the port 11 for pressure relief. After the pressure relief is completed, the compression spring 15 can exert a downward force on the drive plate 13, making the surface of the sphere 14 contact the upper end of the small rubber sleeve 12 for sealing, which can prevent the temperature loss in the fermentation tank 1.

[0059] Specifically, a slide bar 16 is fixedly installed on the upper end surface of the drive plate 13, and the end of the slide bar 16 away from the drive plate 13 penetrates the upper wall of the housing 9;

[0060] The number of the slide bars 16 is two pairs. Under the action of the slide bars 16, the drive plate 13 can move more stably in the housing 9.

[0061] Specifically, a dust-proof net 17 is fixedly installed in the port 11;

[0062] The dust-proof net 17 can block foreign impurities from the outside, prevent them from entering the housing 9 and then entering the fermentation tank 1 through the through hole 10, causing the feed inside to deteriorate and affecting the fermentation quality.

[0063] Specifically, a heat preservation shell 18 is fixedly installed on the outer surface of the fermentation tank 1, and heat preservation cotton 19 is arranged inside the heat preservation shell 18;

[0064] The heat preservation shell 18 and the heat preservation cotton 19 can keep the temperature heated by the electric heating wire 4 warm, prevent the temperature from losing and cause waste of electric energy.

[0065] Specifically, a scraper 20 is arranged inside the fermentation tank 1. One end of the scraper 20 is in sliding contact with the inner wall surface of the fermentation tank 1, and the other end surface is fixedly connected with one end of the stirring rod 8;

[0066] The rotation of the rotating shaft 7 can drive the stirring rod 8 and the scraper 20 to rotate at the same time, so that the scraper 20 can scrape the inner wall surface of the fermentation tank 1 to prevent the feed from adhering to the inner wall of the fermentation tank 1.

[0067] Working principle: First, the staff rotates the bolt to separate the sealing cover 2 from the fermentation tank 1. At this time, the staff adds the feed to be fermented into the fermentation tank 1, and then uses the bolt again to fix the sealing cover 2 to the fermentation tank 1 to seal the fermentation tank 1. At this time, the staff starts the motor and operates the controller 6 to supply power to the electric heating wire 4 by an external power supply device, so that the electric heating wire 4 heats the side wall of the fermentation tank 1 to increase the temperature inside the fermentation tank 1. At this time, the rotation of the output end of the motor can drive the rotating shaft 7 and the stirring rod 8 to rotate. The rotation of the stirring rod 8 can stir the feed, making the feed evenly heated and improving the fermentation efficiency. At the same time, the rotation of the stirring rod 8 can drive the scraper 20 to scrape off the feed attached to the inner wall surface of the fermentation tank 1, so that the stirring rod 8 can stir it, improving the fermentation quality of the feed. At the same time, the temperature sensor 5 can detect the temperature inside the fermentation tank 1, facilitating the staff to control the heating power of the electric heating wire 4 by the controller 6 to adjust the temperature. Meanwhile, when the temperature inside the fermentation tank 1 rises and causes the pressure inside to be too high, the gas inside can enter the through hole 10 and exert an upward force on the sphere 14, causing the driving plate 13 to move upward and compressing the compression spring 15 at the same time. At this time, the gas flowing out of the through hole 10 can be discharged to the outside through the through port 11 for pressure relief. When the pressure relief is completed, the compression spring 15 can exert a downward force on the driving plate 13, making the surface of the sphere 14 contact the upper end of the small rubber sleeve 12 for sealing, preventing the temperature inside the fermentation tank 1 from escaping. After fermentation is completed, the staff opens the valve to open the discharge pipe, and the fermented feed can be discharged, bringing convenience to people.
