Description

Technical Field

[0001] The invention belongs to the technical field of antibiotic-free aquaculture and relates to a fermentation tank, in particular to a fermentation tank for antibiotic-free aquaculture feed. Background Art

[0002] Antibiotic-free farming is the abbreviation of antibiotic-free farming, which means that no antibiotics of any kind are used in the farming process, especially no antibiotics for humans and animals. Antibiotic-free fermented feed is a biological fermented feed that uses microorganisms and compound enzyme microbial feed fermentation agent strains to convert feed raw materials into microbial bacterial proteins, bioactive small peptide amino acids, microbial active probiotics, and compound enzyme preparations.

[0003] Antibiotic-free feed can not only make up for the amino acids that are easily lacking in conventional feed, but also quickly convert the nutritional components of other roughage raw materials, promote the reproduction of intestinal flora, and inhibit the growth of pathogenic microorganisms, thereby replacing the use of antibiotics in the diet and reducing the threats posed by antibiotics to the environment and food safety.

[0004] After searching, for example, Chinese patent documents disclose a fermentation tank for antibiotic-free feed [Application No.: CN202223056250.6; Publication No.: CN218596366U]. This fermentation tank puts the feed to be fermented into the conveying box through a feeding hopper, and then starts the motor to drive the conveyor belt to convey the feed through the conveying wheel.

[0005] Although the fermentation tank disclosed in the patent can improve the uniformity of additives and feed by means of a vibrator and a feeding hopper, due to the large internal structure of the tank, materials tend to accumulate at the bottom after entering the tank, resulting in different fermentation efficiencies of the feed and additives at the bottom and top during fermentation, affecting the overall fermentation cycle of the feed. When the internal bacterial flora is quite different, it may even affect the fermentation quality of the feed, increasing the production cost of the feed. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a fermentation tank for antibiotic-free livestock feed.

[0012] The top end of the vertical rod is fixedly connected with a worm wheel, and one side of the worm wheel is meshedly connected with a worm, and the worm is connected to the mounting frame through a sleeve shaft, and the other end of the worm is connected to a cross bar through a synchronous pulley unit, and the cross bar is rotatably arranged inside the feeding tube, and the worm is driven by a driving unit;

[0013] A fixing plate is fixedly connected to the lower inner wall of the fermentation tank, and a plurality of mixing rod units are arranged above the fixing plate, and the mixing rod units are rotatably arranged on the upper inner wall of the fermentation tank;

[0014] The inner wall of the temperature control tank forms two cavities arranged up and down through a fixedly connected partition, and a heat inlet pipe and an exhaust pipe are respectively arranged on both sides of the cavity;

[0015] The interior of the feeding pipe is connected with a cross bar via a rotating shaft, and a material spreading assembly is fixedly installed on the inner side of the cross bar.

[0016] The working principle of the present invention is: additives and feed are spread horizontally through the spreading component, and the fermenter is rotated outside the dividing component so that the materials are scattered and fall into the inside of the fermenter, and the mixing rod unit and the dividing component are set to make the materials dispersed inside the fermenter, thereby ensuring the uniformity of the materials inside the fermenter and realizing efficient pretreatment of the materials before fermentation. During fermentation, the fixed plate is set to achieve flexible stratification of the materials inside the fermenter according to the material amount, and the upper and lower layers are independently temperature controlled by the setting of the external temperature control tank, thereby avoiding the problem of uneven fermentation of the upper and lower layers and ensuring the fermentation quality of the feed.

[0017] The side wall of the material passage pipe is provided with a plurality of groups of material spreading openings at equal intervals in an annular manner.

[0018] By adopting the above structure, part of the material in the material passage pipe can be scattered out through the material spreading port during circulation, thereby ensuring the dispersion effect of the material.

[0019] The shrinking tube is arranged in a "V"-shaped structure, and a through material groove is opened in an annular manner at equal intervals on the side wall of the shrinking tube, and the aperture of the opening of the through material groove is smaller than the aperture of the opening of the material spreading port.

[0020] With the above structure, the setting of the constricted pipe at the bottom facilitates the discharge of materials and avoids material blockage. Moreover, the fermenter rotates outside the material distribution component, so that the material distribution component can evenly distribute the materials inside the fermenter.

[0021] The mixing rod unit comprises a rotating rod rotatably arranged above the fermentation tank, the rotating rod is located at the outer periphery of the shrinking tube, and a gear plate is fixedly connected to the top of the rotating rod, an inner gear plate is meshedly connected to the outer wall of the gear plate, and the inner gear plate is fixedly connected to the top of the temperature control tank;

[0022] The outer wall of the rotating rod is equidistantly provided with a plurality of groups of bulk rods, and the rotating rod is annularly equidistantly provided with a plurality of groups about the axis of the connecting tube.

[0023] With the above structure, under the action of the mixing rod unit, the mixing rod unit can rotate by the rotation of the fermenter, which is convenient for the mixing rod unit to disperse the material above the material distribution component, ensuring the dispersion effect of the material when it flows downward, which is beneficial to improve the uniformity of the material inside the fermenter.

[0024] The middle part of the fixed plate is a raised material guide plate, and a plurality of through holes are formed on the surface of the fixed plate;

[0025] The material guide plate is arranged in a conical structure.

[0026] With the above structure, under the action of the material guide plate, the material distributing assembly rotates through the mixing rod unit to discharge the material into the surface of the fixed plate and enters the bottom of the fermentation tank through the through hole, thereby ensuring the stratification effect of the material inside the fermentation tank.

[0027] The bottom end of the fermentation tank is connected with a discharge pipe, and the discharge pipe is opened and closed by a solenoid valve.

[0028] With the above structure, the fermented feed can be stably discharged through the setting of the discharge pipe, and under the action of the electromagnetic valve, the discharge of the fermentation tank is uniform, achieving stable discharge quality.

[0029] The central axis of the temperature-control tank coincides with the central axis of the fermentation tank, and the bottoms of the two cavities in the temperature-control tank are both connected with cooling liquid pipes.

[0030] By adopting the above structure, a temperature control tank is arranged outside the fermentation tank, so that the temperature control tank can control the fermentation tank at different temperatures through the upper and lower groups of cavities, thereby ensuring the uniformity of fermentation. Moreover, by setting the cooling liquid pipe, it is convenient to discharge the steam inside the temperature control tank, which facilitates the inspection and maintenance of the device and reduces the use cost.

[0031] The driving unit is a driving motor, and the driving motor is fixedly mounted on one side of the mounting frame, and the output end of the driving motor is fixedly connected with a worm.

[0032] With the above structure, the drive motor is arranged to enable the material spreading assembly and the fermentation tank to rotate stably, so that the internal mixing rod unit can mix materials efficiently, the structure is simple, and the driving cost is low.

[0033] The material spreading assembly comprises a barrel, and both ends of the barrel are fixedly connected with cross bars, and a plurality of groups of material passing holes are arranged at the bottom end of the barrel.

[0034] With the above structure, under the action of the cross bar, the driving motor can synchronously drive the cross bar to rotate through the transmission of the synchronous belt pulley unit. Through the rotation connection of the cross bar inside the feeding pipe, the cross bar drives the spreading assembly on both sides to rotate and spread the material, which is convenient for the additive and the feed to be effectively mixed and spread downwards. Moreover, under the action of the rotating spreading, the dispersion effect of the initial feeding of the material is ensured.

[0035] The barrel is a polyhedral structure with a feed port disposed on it. The feed port is arranged opposite to the material passage hole, and two closing plates are slidably connected inside the feed port. A handle is integrally connected to the surface of the closing plate, and the handles of the two closing plates are both made of magnetic material.

[0036] By adopting the above structure, the two sets of closing plates can close the barrel through magnetism, so that the barrel can be closed through the closing plates when rotating, and the material can be discharged alone through the through hole, ensuring the safety of the material inside the barrel, avoiding the material from being scattered through the feed port when rotating, and improving the flexibility of the barrel.

[0037] Compared with the prior art, the dry electrode material detection device of the present invention has the following advantages:

[0038] 1. In the present invention, a fermentation tank is rotatably arranged inside a temperature-controlled tank. Under the effect of the temperature-controlled tank forming two upper and lower chambers, a fixed plate is arranged at the bottom of the fermentation tank, so that the interior of the fermentation tank is divided into upper and lower parts, which is convenient for isolating the interior of the fermentation tank and circulating the materials through the through holes, thereby facilitating the circulation of materials inside the fermentation tank. Under the effect of the temperature-controlled tank, the problem of excessive fermentation of materials at the bottom of the fermentation tank is avoided, the problem of large differences in the bacterial flora inside the fermentation tank can be prevented, and it is beneficial to improve the fermentation efficiency of the feed and shorten the production cycle.

[0039] 2. In the present invention, by setting a material distribution component inside the fermentation tank, the material can enter the fermentation tank evenly, and by setting a mixing rod unit, the material can be dispersed for a second time, thereby ensuring the dispersion effect of the material inside the fermentation tank and facilitating efficient fermentation of the material.

[0040] 3. In the present invention, under the action of the spreading component, the material is rotated and spread before entering the fermentation tank, which is convenient for the material to enter the feeding pipe in a dispersed manner, and is convenient for the feed and additive to be mixed and fed, ensuring the uniformity of the material mixing, which is beneficial to accelerate the fermentation efficiency of the feed. In addition, it is driven by a synchronous pulley unit, has a simple structure, saves driving costs, has high synchronization, and realizes uniform and synchronous feeding.

[0041] 4. In the present invention, the fermenter can be rotated through the outer gear ring through the meshing connection with the driving gear, so that the fermenter can be rotated outside the material distribution assembly through the bearing, and the fermenter can be rotated to receive materials, and the mixing rod unit is connected to the inside of the fermenter through the meshing action of the gear plate and the inner gear plate. When the fermenter drives the mixing rod unit to rotate, the mixing rod unit rotates synchronously through the inner gear plate, so that the mixing rod unit can be dispersed for the second time above the bottom plate, further improving the dispersion effect of the material inside the fermenter, and realizing the efficient pretreatment of the material before fermentation.

[0042] 5. In the present invention, by arranging a partition inside the temperature-controlling tank and installing the temperature-controlling tank outside the fermentation tank, the temperature-controlling tank can adjust the heating temperature of the fermentation tank through the exhaust pipe and the heat inlet pipe arranged up and down, which is conducive to achieving the uniformity of the fermentation environment at the upper and lower parts of the fermentation tank, avoiding the problem of excessive fermentation caused by the accumulation of materials at the bottom of the fermentation tank, and improving the fermentation quality of the feed.

Specifically, a temperature-control tank 2 is sleeved and installed on the outer wall of the fermentation tank 3, and the central axis of the temperature-control tank 2 coincides with the central axis of the fermentation tank 3. In addition, in consideration of graded temperature control of the fermentation tank 3, upper and lower cavities are formed on the inner wall of the temperature-control tank 2 by a fixedly connected partition 20, and heat inlet pipes 21 and exhaust pipes 22 are respectively arranged on both sides of the upper and lower cavities, and cooling liquid pipes 24 are connected to the bottoms of the two groups of cavities in the temperature-control tank 2, so as to facilitate independent temperature control of the fermentation tank 3. At the same time, a discharge pipe is connected to the bottom end of the fermentation tank 3, and the discharge pipe is opened and closed by an electromagnetic valve 23, so that the fermented feed can be discharged stably, and under the action of the electromagnetic valve 23, the discharge of the fermentation tank 3 is uniform, so as to achieve stable discharge quality, and a driving component 4 is fixedly connected to the top of the temperature-control tank 2 to drive the fermentation tank 3 to rotate;

[0056] Further, the driving assembly 4 includes a mounting frame 401, and the mounting frame 401 is fixedly installed on the top of the temperature-controlled tank 2. At the same time, a side plate 402 is fixedly connected to the inner side of the mounting frame 401, and the inside of the side plate 402 is rotatably connected to a vertical rod 403 through a connecting shaft, and the bottom end of the vertical rod 403 is connected to a driving gear 405, and the driving gear 405 is meshed and connected to one side of the outer gear ring 7, and the outer gear ring 7 is fixedly sleeved on the outer wall of the connecting pipe 6, and the connecting pipe 6 is fixedly installed on the top of the fermentation tank 3. Through such an arrangement, the driving assembly 4 can stably drive the fermentation tank 3 through the outer gear ring 7, so that the fermentation tank 3 can rotate inside the temperature-controlled tank 2.

[0057] The top of the vertical rod 403 is fixedly connected with a worm wheel 404, and one side of the worm wheel 404 is meshedly connected with a worm 406, and the other end of the worm 406 is connected to the cross bar 13 through the synchronous pulley unit 12, and the cross bar 13 is rotatably arranged inside the feeding tube 5, and the worm 406 is driven by a driving unit, and the driving unit is a driving motor 25, and the driving motor 25 is fixedly installed on one side of the mounting frame 401. Through the setting of the driving motor 25, the material spreading assembly 14 and the fermentation tank 3 can rotate stably, which is convenient for the internal mixing rod unit to mix efficiently, and the structure is simple and the driving cost is low;

[0058] like Figure 1-Figure 10 As shown, a connecting pipe 6 is fixedly connected to the top of the fermentation tank 3, and the inner wall of the connecting pipe 6 is rotatably connected to the material distribution component 16 through a bearing 15, and a feeding pipe 5 is fixedly connected to the top of the material distribution component 16, and the feeding pipe 5 is fixedly installed on the surface of the driving component 4;

[0059] Specifically, the material distribution component 16 includes a feed pipe 1601, and the feed pipe 1601 is rotatably installed on the inner wall of the connecting pipe 6 through a bearing 15. The side wall of the feed pipe 1601 is annularly and equidistantly provided with a plurality of groups of material spreading ports 1605. When the material inside the feed pipe 1601 is circumferentially distributed, part of the material can be spread out through the material spreading ports 1605, thereby ensuring the dispersion effect of the material. The bottom end of the feed pipe 1601 is fixedly connected to a constriction pipe 1602, and the bottom end of the constriction pipe 1602 is fixedly installed with a bottom plate 1603, and A plurality of feeding ports 1604 are formed inside the bottom plate 1603, and a through material slot is formed in an annular manner at equal intervals on the side wall of the necking tube 1602. A plurality of mixing rod units are formed outside the necking tube 1602, and the mixing rod units are rotatably disposed inside the fermentation tank 3. The arrangement of the necking tube 1602 at the bottom facilitates the discharge of materials and avoids material blockage. Furthermore, the fermentation tank 3 rotates outside the material distribution component 16, so that the material distribution component 16 evenly distributes the materials inside the fermentation tank 3.

[0060] The mixing rod unit is rotatably arranged on the upper inner wall of the fermentation tank 3. The mixing rod unit includes a rotating rod 10 rotatably arranged above the fermentation tank 3. A plurality of groups of bulk material rods 11 are equidistantly arranged on the outer wall of the rotating rod 10, and a plurality of groups of bulk material rods 11 are equidistantly arranged in a circular manner about the axis of the connecting pipe 6. Under the action of the mixing rod unit, the mixing rod unit can rotate by the rotation of the fermentation tank 3, so that the mixing rod unit can disperse the materials above the material distribution component 16, thereby ensuring the dispersion effect of the materials when flowing downward, and facilitating improving the uniformity of the materials inside the fermentation tank 3. At the same time, a gear plate 9 is fixedly connected to the top of the rotating rod 10, and an inner gear plate 8 is meshedly connected to the outer wall of the gear plate 9, and the inner gear plate 8 is fixedly connected to the top of the temperature control tank 2. Through the meshing connection between the inner gear plate 8 and the gear plate 9, when the fermentation tank 3 rotates inside the temperature control tank 2, the gear plate 9 drives the rotating rod 10 to rotate inside the fermentation tank 3, thereby ensuring the dispersion effect of the internal materials.

[0061] A fixed plate 17 is fixedly connected to the inner wall below the fermentation tank 3, and a plurality of mixing rod units are arranged above the fixed plate 17. A convex guide plate 18 is arranged in the middle of the fixed plate 17. The guide plate 18 is arranged in a conical structure. Under the action of the guide plate 18, the material feeding component 16 is rotated to discharge the material through the mixing rod unit and enter the surface of the fixed plate 17. A plurality of through holes 19 are formed on the surface of the fixed plate 17, and the aperture of the through hole 19 is smaller than the material spreading port 1605, so that the material passes through the through hole 19 into the bottom of the fermentation tank 3, thereby ensuring the stratification effect of the material inside the fermentation tank 3.

[0062] The interior of the feeding tube 5 is connected with a cross bar 13 through a rotating shaft, and the cross bar 13 is fixedly installed at both ends of the spreading assembly 14. Under the action of the cross bar 13, through the transmission of the synchronous pulley unit 12, the driving motor 25 can synchronously drive the cross bar 13 to rotate. Through the rotation connection of the cross bar 13 inside the feeding tube 5, the cross bar 13 drives the spreading assembly 14 on both sides to rotate and spread the material, which is convenient for the additives and feed to be evenly spread downward, ensuring the dispersion effect of the initial feeding of the material. Specifically, the spreading assembly 14 includes a barrel 1401, and the barrel 1 Both ends of 401 are fixedly connected with cross bars 13, and a plurality of material passing holes 1402 are provided at the bottom end of the barrel 1401. The barrel 1401 is a polyhedron structure, and two groups of closing plates 1403 are slidably connected to the surface of the barrel 1401. The closing plates 1403 are arranged in an "L"-shaped structure, and the two groups of closing plates 1403 are connected magnetically. The two groups of closing plates 1403 can close the barrel 1401 by magnetism, so that the barrel 1401 can stably discharge materials through the material passing holes 1402 when rotating, thereby improving the flexibility of using the barrel 1401.

[0063] The working principle of the present invention is as follows: when in use, feed and additives are added into the interior of the barrel 1401, and the barrel 1401 is closed by the closing plate 1403, and a through hole 1402 is opened at the bottom of the barrel 1401 to enter the feeding tube 5. When the driving motor 25 is powered on and rotated, under the action of the synchronous pulley unit 12, the cross bar 13 drives the barrel 1401 to rotate, so that the barrel 1401 drives the material to rotate through the through hole 1402 and enter the feeding tube 5, thereby ensuring the material spreading and feeding effect. Furthermore, by connecting the material distribution component 16 at the bottom of the feeding pipe 5, the material enters the feeding pipe 1601 after being spread. Under the action of the material spreading port 1605 provided on the peripheral side of the feeding pipe 1601, the worm gear 404 and the worm 406 are meshed and connected, so that the fermentation tank 3 rotates outside the material distribution component 16, so that the material is dispersed in the fermentation tank 3 through the material spreading port 1605. Furthermore, by connecting the bottom plate 1603 at the bottom end of the feeding pipe 1601 and arranging the mixing rod unit above the bottom plate 1603, the fermentation tank 3 rotates outside the material distribution component 16, so that the material is dispersed in the fermentation tank 3 through the material spreading port 1605. When the tank 3 rotates, the mixing rod unit rotates by meshing connection between the gear plate 9 and the inner gear plate 8, so that the mixing rod unit can carry out secondary material dispersing inside the fermentation tank 3, and disperse the material downward through the discharge port 1604. At the same time, by fixing the fixing plate 17 inside the fermentation tank 3, the fixing plate 17 drives the material to rotate. At the same time, under the action of the through hole 19, part of the material enters the bottom of the fermentation tank 3, so that the material can be fermented synchronously above and below the fixing plate 17 and circulate through the through hole 19. During fermentation, heat is introduced into the interior of the temperature control tank 2 through two groups of heat inlet pipes 21, so that the fermentation tank 3 is heated. Since the accumulation of materials at the bottom easily leads to a high temperature at the bottom of the fermentation tank 3, the temperature can be reduced by the lower chamber of the temperature control tank 2, and the surrounding side can be evenly heated by the rotation of the fermentation tank 3 inside the temperature control tank 2. Through such a setting, the material can be stably and evenly fermented inside the fermentation tank 3, avoiding large differences in fermentation of the upper and lower flora, thereby ensuring the fermentation quality of the feed.

[0064] In summary, additives and feed are spread laterally through the spreading component 14, and the fermenter 3 is rotated outside the dividing component 16 so that the materials are scattered and fall into the fermenter 3, and the mixing rod unit and the dividing component 16 are set, so that the materials are dispersed for the second time inside the fermenter 3, thereby ensuring the uniformity of the materials inside the fermenter 3 and realizing efficient pretreatment of the materials before fermentation. During fermentation, the fixed plate 17 is set, so that the materials inside the fermenter 3 can be flexibly stratified according to the material amount, and the upper and lower temperatures are independently controlled by the setting of the external temperature control tank 2, thereby avoiding the problem of uneven fermentation in the upper and lower layers, ensuring the fermentation quality of the feed, and solving the problem that the existing fermentation tank cannot ferment in layers, resulting in uneven fermentation in the tank, large differences in bacterial growth, and affecting the fermentation quality of the feed.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
