Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, in particular to a fermentation tank with temperature control performance for feed fermentation. Background Art

[0002] Feed fermentation is usually carried out by natural fermentation and fermentation by inoculating commercial lactic acid bacteria. The quality of feed produced by natural fermentation is generally unstable, and it is easily infected by miscellaneous bacteria, and the feeding effect of pigs varies greatly. The quality of feed produced by inoculating commercial lactic acid bacteria is easier to control, but the cost is relatively higher.

[0003] With the development of animal husbandry, feed fermentation agents are also sought after by farmers. People not only pursue pork with better meat quality, but farmers are also looking for feed that can produce high-quality pork. The feed must be low-cost and good for the growth of pigs. When using existing feed fermentation tanks, for some aerobic fermentations, they are simply placed in the tank and allowed to ferment on their own. The speed is slow, the fermentation uniformity is insufficient, and the controllability of the internal temperature is insufficient. Therefore, it is necessary to design a fermentation tank that can solve the above problems. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a fermentation tank with temperature control performance for feed fermentation, aiming to solve the problem of slow and uneven fermentation speed.

[0005] A fermentation tank with temperature control performance for feed fermentation, comprising an outer tank, an inner tank, and a temperature control cabinet; four sets of mounting plates are arranged at the four corners of the front and rear side walls of the inner tank, the inner tank is fixed to the inner middle part of the outer tank by the mounting plates, feeding ports are opened on both sides of the top of the inner tank, and the feed to be fermented is placed inside the inner tank for fermentation.

[0006] In order to ensure the constant temperature and automatic temperature control capability inside the outer tank, a set of temperature control cabinets are fixedly installed on the top of the outer tank, a set of PLC controllers are arranged inside the temperature control cabinets, a set of refrigerators and heaters are arranged on both sides of the temperature control cabinets, and a circle of flowing gas temperature control chambers are arranged on the outside of the outer tank, and the top two sides of the flowing gas temperature control chambers are connected to the corresponding refrigerators and heaters through external pipes;

[0007] A stirring mechanism is arranged inside the inner tank, and an air inlet and outlet pipe is opened outwardly at the top of one side wall of the outer tank, and an electromagnetic valve is arranged on the air inlet and outlet pipe. The gas inside the outer tank can enter and exit through the air inlet and outlet pipe, so as to facilitate aerobic fermentation. In order to facilitate the gas entering through the air inlet and outlet pipes to fully contact the feed inside the inner tank, and the gas to circulate inside the outer tank, a group of wind driving mechanisms are respectively arranged on one side of the top of the inner tank and the other side of the bottom. The wind driving mechanism includes a horizontal gas pushing plate, and the gas pushing plate is slidably connected to the side wall of the inner tank on the side close to the inner tank. A group of nuts are fixedly installed on the end of the gas pushing plate close to the side wall of the outer tank. The nuts are slidably connected to a group of vertical ball screws, and the ball screws are arranged in a lifting cavity opened inside the side wall of the outer tank. Retaining rings are fixedly installed on both ends of the ball screw, and the ends of the retaining rings are rotatably connected to the inner wall of the lifting cavity through a rotating rod. The rotation of the ball screw drives the nut to move up and down, thereby driving the gas pushing plate to move alternately on both sides of the inner tank, thereby making the gas inside the outer tank outside the inner tank flow.

[0008] As a further solution of the present invention: in order to reduce energy consumption, a set of driving gears is fixedly installed in the middle of the rotating shaft, and a set of height-adjustable transition gears are meshed on the side of the driving gear pointing to the corresponding ball screw, and a set of driven gears fixedly installed on the corresponding rotating rod are meshed on one side of the transition gear. When the servo motor is started to drive the stirring rod to run, the connection between the driving gear, the transition gear and the driven gear is used to control the rotation of the ball screw. A set of electric lifting rods with ends fixed on the inner wall of the outer tank are fixedly installed in the middle of the top of the transition gear. The height of the transition gear is adjusted by the electric lifting rod, so as to control its two sides to mesh with the driving gear and the driven gear, and then it is selected whether to use the gas push plate to work according to the needs.

[0009] As a further solution of the present invention: a heat-conducting layer is provided inside the side wall of the outer tank to facilitate the temperature transfer to the outer tank, and a heat-insulating layer is provided outside the flowing gas temperature control chamber. The inner top wall and bottom of the outer tank are respectively provided with a temperature detector for measuring the inner temperature of the outer tank at all times. The temperature detector is electrically connected to the PLC controller, and the temperature detected by the temperature detector is received by the PLC controller, and then the PLC controller analyzes and processes the received information, and then controls the corresponding refrigerator or heater to operate, so that the gas generated by it is input into the inner part of the flowing gas temperature control chamber.

[0010] As a further solution of the present invention: the stirring mechanism includes a stirring rod vertically passing through the middle of the inner tank, the two ends of the stirring rod movably passing through the inner tank and fixedly connected to a rotating shaft placed inside the outer tank, the end of the rotating shaft located at the lower side of the inner tank is rotatably connected to the inner wall of the outer tank through a bearing, and the outer wall of the stirring rod located inside the inner tank is evenly and evenly provided with multiple groups of stirring blades. The top end of the rotating shaft located at the top of the inner tank is rotatably connected to a group of servo motors fixed to the top of the outer tank, and the stirring rod is driven to rotate by starting the servo motor, and then the stirring blades inside the inner tank are driven to stir the fermenting feed, thereby increasing the uniformity of fermentation.

[0011] As a further solution of the present invention: in order to further increase the ability of the gas inside the outer tank to enter the inner tank, ventilation holes are evenly opened on the outer wall of the rotating shaft, and an inner tube is arranged inside the rotating shaft. The inner tube extends to the inside of the stirring rod and is interconnected with the stirring blades through multiple groups of branch pipes, and an air outlet is opened on the outside of the stirring blade. Through the arrangement of the ventilation holes, the inner tube and the air outlet, the gas inside the outer tank is easily input into the inner tank, thereby accelerating aerobic fermentation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: by arranging a temperature control cabinet on the top of the outer tank, and then electrically connecting the temperature control cabinet with a temperature detector to control the operation of the corresponding refrigerator and heater, and then adjusting the temperature inside the outer tank through a flowing gas temperature control chamber arranged outside the outer tank, the function of automatic temperature control is realized;

[0013] By arranging a stirring mechanism inside the inner tank, the feed and gas inside the inner tank are stirred by the stirring mechanism to facilitate full contact of the gas, thereby accelerating the aerobic fermentation of the feed;

[0014] By setting a servo motor on both sides of the inner tank to rotate, the gas push plate is driven to rise and fall under the connection of the driving gear, the transition gear and the driven gear, and then the gas outside the inner tank is driven to circulate and flow, and then enters the inner tube through the ventilation hole, and finally is released to the inside of the inner tank through the stirring blades, thereby increasing the force of the gas entering the inner tank and contacting the feed, thereby increasing the fermentation efficiency.
