Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a fermentation tank for preparing agricultural microbial fertilizer. Background Technology

[0002] Microbial fermentation refers to the process by which microorganisms, under suitable conditions, transform raw materials into products needed by humans through specific metabolic pathways. The production level of microbial fermentation mainly depends on the genetic characteristics of the microbial strain and the culture conditions, and it is a type of fertilizer used in agricultural production.

[0003] Microbial fertilizers require fermentation during production, typically using fermentation tanks. However, current fermentation tanks often fail to mix effectively, resulting in fertilizer adhering to the inner walls and hindering proper fermentation. Furthermore, waste accumulates at the bottom during mixing, making the process inconvenient. When discharging after fermentation, material adheres to the tank walls, wasting resources and promoting microbial growth, negatively impacting subsequent production. Temperature control is crucial during fermentation; excessively high temperatures kill bacteria and reduce product quality, while insufficient temperatures prevent complete fermentation. Therefore, to ensure product quality, we propose a fermentation tank for agricultural microbial fertilizer preparation. Utility Model Content

A feed pipe 3 is fixedly installed on the top of the tank cover 2. A temperature sensor 15 is installed inside the fermentation chamber 101.

[0019] The stirring assembly 5 includes a drive rod 51, which is rotatably mounted on the top wall of the tank cover 2. A U-shaped scraper 53 is fixedly installed at the bottom of the drive rod 51, and the outer wall of the U-shaped scraper 53 abuts against the inner wall of the fermentation chamber 101. Multiple stirring rods 52 are evenly fixedly installed on the outer surface of the drive rod 51 from top to bottom. The end of the stirring rod 52 away from the drive rod 51 is fixedly connected to the inner wall of the U-shaped scraper 53. The output end of the motor 4 passes through the tank cover 2 and is fixedly connected to the top of the drive rod 51. In use, the motor 4 drives the drive rod 51 to rotate, which in turn drives the stirring rods 52 to rotate.

[0020] The linkage component 17 includes an electric telescopic rod 171, which is fixedly installed at the bottom of the mounting cavity 61. A buffer block 172 is fixedly installed at the top of the electric telescopic rod 171. A movable cavity 1721 is opened inside the buffer block 1721.

[0021] In practical use, when it is necessary to adjust the temperature inside the fermentation chamber 101, the electric telescopic rod 171 is activated, which drives the buffer block 172 to move upward. The buffer block 172 drives the mounting plate 176 to move upward, and the mounting plate 176 drives the cross block 177 to move upward. When the cross block 177 is engaged with the cross groove 531, the cross block 177 enters the cross groove 531. At the same time as the U-shaped scraper 53 rotates, the cross block 177 is driven to rotate through the cross groove 531. The cross block 177 drives the mounting plate 176 to rotate. The mounting plate 176 will drive the linkage rod 6 to rotate through the limiting block 178. The linkage rod 6 drives the continuous water supply component 7 and the heating component 8 to work, thereby adjusting the material temperature inside the fermentation chamber 101.

[0022] The check valve assembly 9 includes a valve body 91, a sealing plug 96, and a fixing plate 94. The valve body 91 has a flow cavity 9101 inside, with a second inlet 92 at one end and a second outlet 93 at the other end. The fixing plate 94 is located in the middle of the flow cavity 9101, and multiple connecting rods 95 are evenly fixedly installed on its outer surface. The end of each connecting rod 95 away from the fixing plate 94 is fixedly connected to the inner wall of the flow cavity 9101. One end of the sealing plug 96 matches the second inlet 92, and the other end of the sealing plug 96 is fixedly installed in the middle. The device is equipped with a first slide rod 97. The end of the first slide rod 97 away from the sealing plug 96 slides through the fixing plate 94 and is fixedly installed with a second baffle 912. A first spring 98 is sleeved on the outer surface of the first slide rod 97. Two L-shaped plates 910 are symmetrically distributed and fixedly installed on the end of the fixing plate 94 near the sealing plug 96. Second slide rods 99 are fixedly installed on both the upper and lower sides of the end of the sealing plug 96 near the fixing plate 94. The end of the second slide rod 99 away from the sealing plug 96 slides through the L-shaped plate 910 and is fixedly installed with a first baffle 911. The double check valve assembly 9 ensures unidirectional water flow.

[0023] The continuous water supply assembly 7 includes a first fixed cylinder 71, an elliptical disk 72, and a piston 73. The first fixed cylinder 71 is fixedly installed on the middle of the inner wall of the water chamber 102. A water supply pipe 77 is fixedly installed on the lower right side of the inner wall of the first fixed cylinder 71. The water supply pipe 77 is connected to the heating assembly 8. The piston 73 slides on the right side of the inner wall of the first fixed cylinder 71. The linkage rod 6 rotates through the first fixed cylinder 71 and is connected to the heating assembly 8. The elliptical disk 72 is fixedly installed on the outer surface of the linkage rod 6. Elliptical grooves 721 are provided at both the upper and lower ends of the elliptical disk 72. An elliptical groove 721 is fixedly installed on the left end of the piston 73. The connecting plates 74 are distributed vertically. Each of the two connecting plates 74 has a third slide rod 76 fixedly installed at one end close to each other. The ends of the two third slide rods 76 away from the connecting plates 74 on the same side slide in the elliptical slide groove 721 located on the same side. A slider 75 is fixedly installed in the middle of the left end of the piston 73. The outer surface of the slider 75 is in contact with the outer surface of the elliptical disk 72. The right end of the first fixed cylinder 71 has a first water inlet 78. The first water inlet 78 is connected to the second outlet 93 of the check valve assembly 9. The second inlet 92 of the check valve assembly 9, which is connected to the continuous water supply assembly 7, is in communication with the water chamber 102.

[0024] In practical use, when motor 4 drives drive rod 51 to rotate, drive rod 51 drives U-shaped scraper 53 to rotate. U-shaped scraper 53 drives linkage rod 6 to rotate via linkage assembly 17. Linkage rod 6 drives elliptical disk 72 to rotate. While elliptical disk 72 rotates, it drives slide rod to slide within elliptical groove 721. While sliding, third slide rod 76 drives piston 73 to move left and right reciprocally within first fixed cylinder 71 via connecting plate 74. When piston 73 moves to the left, negative pressure is formed in the cavity of first fixed cylinder 71 on the left side of piston 73, and water cavity 1... Water in chamber 102 enters the flow chamber 9101 through the second inlet 92 of the check valve assembly 9, squeezing the sealing plug 96. Then, it enters the first fixed cylinder 71 through the second outlet 93 from the first inlet 78. When the piston 73 moves to the right, it squeezes the water, and the water on the right side of the piston 73 is squeezed and transported to the heating chamber 83 through the water delivery pipe 77. In summary, the rotation of the elliptical disk 72 drives the piston 73 to move left and right, thereby continuously pumping water from the water chamber 102 into the first fixed cylinder 71, and then transporting the water to the heating chamber 83.

[0025] The heating assembly 8 includes a second fixed cylinder 81, a driving bevel gear 84, and a rotating rod 86. The second fixed cylinder 81 is internally divided into a left-right distributed equipment cavity 82 and a heating cavity 83. The water supply pipe 77 is connected to the left side of the top wall of the heating cavity 83. The bottom of the linkage rod 6 rotatably extends through the equipment cavity 82 and is fixedly connected to the driving bevel gear 84. The rotating rod 86 is rotatably installed in the middle of the left and right side walls of the heating cavity 83. The left end of the rotating rod 86 extends through the equipment cavity 82 and is fixedly installed with a driven bevel gear 85. The driving bevel gear 84 and the driven bevel gear 85 mesh. A spiral plate 87 is fixedly installed on the outer surface of the rotating rod 86. The outer edge of the spiral plate 87 is tangent to the inner wall of the heating cavity 83. A ring centered on the rotating rod 86 is fixedly installed on the spiral plate 87. Multiple metal rods 88 are arranged in a ring array, with each metal rod 88 passing through a spiral plate 87. The metal rods 88 are parallel to the rotating rod 86. A heating coil 89 is sleeved on the outer surface of the second fixed cylinder 81, and a protective cover 810 is fixedly installed on the outer surface of the second fixed cylinder 81, covering the heating coil 89. A first outlet 811 is opened at the right end of the second fixed cylinder 81, and the first outlet 811 is connected to the second inlet 92 of the check valve assembly 9. The water inlet pipe 10 is connected to the second outlet 93 of the corresponding check valve assembly 9. The spiral plate 87 and the metal rods 88 are both made of carbon steel, and the heating coil 89 is made of pure copper to reduce the heat generated by the heating coil 89 itself. The input end of the heating coil 89 is electrically connected to an external power supply.

[0026] In operation, the linkage rod 6 drives the active bevel gear 84 to rotate, which in turn drives the driven bevel gear 85 to rotate. The driven bevel gear 85 then drives the rotating rod 86 to rotate, which in turn drives the spiral plate 87 to rotate. As the spiral plate 87 rotates, it pushes the water from the first fixed cylinder 71 to the right. Simultaneously, the rotation of the spiral plate 87 drives the metal rod 88 to rotate. When it is necessary to heat the material in the fermentation chamber 101, current is passed into the heating coil 89, causing it to generate a rapidly changing alternating magnetic field. This alternating magnetic field is cut by the internal spiral plate 87 and metal rod 88, generating alternating currents (eddy currents) within them. These eddy currents cause the charge carriers within the spiral plate 87 and metal rod 88 to move rapidly and randomly. The charge carriers collide and rub against each other, generating heat energy, thus rapidly heating the water in the heating chamber 83. The hot water is then transported to the inlet pipe 10 through the check valve assembly 9. Hot water is then delivered to the spiral temperature regulating channel 104. Its spiral flow channel design increases the heat exchange area, enabling rapid and uniform heating. The hot water transfers heat to the material in the fermentation chamber 101, raising the temperature of the material and greatly improving the heating efficiency. Similarly, when it is necessary to cool down the material in the fermentation chamber 101, simply disconnect the heating coil 89. Then, the continuous water supply assembly 7 delivers cold water from the water chamber 102 to the heating assembly 8, then through the check valve assembly 9 to the inlet pipe 10. The cold water is then delivered to the spiral temperature regulating channel 104. As the cold water flows in the spiral temperature regulating channel 104, it absorbs the temperature of the material in the fermentation chamber 101, thereby lowering the temperature of the material in the fermentation chamber 101. Then, the hot water is delivered to the return pipe 12. The heat sink 16 on the return pipe 12 dissipates heat from the hot water in the return pipe 12, causing the hot water temperature to drop rapidly. The hot water in the return inlet chamber 102 returns to a cold water state.

[0027] A current regulating module 14 is fixedly installed at the bottom of the fermentation tank body 1. The current regulating module 14 is electrically connected to the heating coil 89. The current regulating module 14 regulates the current of the heating coil 89, thereby regulating the magnetic field strength, which in turn regulates the heat of the spiral plate 87 and the metal rod 88, and thus regulates the temperature of the hot water.

[0028] The fermenter body 1 is fixedly equipped with multiple self-locking casters 11 at its bottom, which facilitates the movement of the entire fermenter.

[0029] The working principle of this utility model is as follows: During use, the fermentation material is added into the fermentation chamber 101 through the feed pipe 3. During fermentation, the motor 4 drives the drive rod 51 to rotate, which in turn drives the stirring rod 52 to rotate, thereby agitating the material in the fermentation chamber 101 and accelerating the fermentation speed. When the temperature sensor 15 senses that the temperature in the fermentation chamber 101 needs adjustment, the electric telescopic rod 171 is activated, causing the buffer block 172 to move upwards. The buffer block 172 then drives the mounting plate 176 to move upwards, which in turn drives the cross block 177 to move upwards. When the cross block 177 engages with the cross groove 531, it enters the cross groove 531. Simultaneously with the rotation of the U-shaped scraper 53... At the same time, the cross block 177 rotates through the cross groove 531, which in turn rotates the mounting plate 176. The mounting plate 176 then rotates the linkage rod 6 through the limiting block 178. The linkage rod 6 drives the continuous water supply assembly 7 and the heating assembly 8 to work. The linkage rod 6 also drives the elliptical disk 72 to rotate. As the elliptical disk 72 rotates, it drives the third slide rod 76 to slide within the elliptical groove 721. While sliding, the third slide rod 76 drives the piston 73 to move back and forth within the first fixed cylinder 71 through the connecting plate 74. When the piston 73 moves to the left, a negative pressure is formed in the cavity of the first fixed cylinder 71 on the left side of the piston 73. Water in the water cavity 102 enters the flow cavity 9101 through the inlet squeeze sealing plug 96 of the check valve assembly 9, and then flows through the second outlet. Water enters the first fixed cylinder 71 through the first inlet 78. As the piston 73 moves to the right, it compresses the water, pushing the water to the right of the piston 73 through the water supply pipe 77 into the heating chamber 83. The rotation of the elliptical disk 72 drives the piston 73 to move left and right, thereby continuously pumping water from the water chamber 102 into the first fixed cylinder 71 and then into the heating chamber 83. The linkage rod 6 drives the driving bevel gear 84 to rotate, which in turn drives the driven bevel gear 85 to rotate. The driven bevel gear 85 drives the rotating rod 86 to rotate, which in turn drives the spiral plate 87 to rotate. As the spiral plate 87 rotates, it pushes the water from the first fixed cylinder 71 to the right, and simultaneously drives the metal rod 88 to rotate. When it is necessary to heat the material in the fermentation chamber 101, current is passed into the heating coil 89 to generate a high-speed alternating magnetic field. The alternating magnetic field lines are cut by the internal spiral plate 87 and metal rod 88, generating an alternating current (i.e., eddy current) in the spiral plate 87 and metal rod 88. The eddy current causes the charge carriers in the spiral plate 87 and metal rod 88 to move at high speed and randomly. The charge carriers collide and rub against each other to generate heat energy, thereby achieving the effect of rapidly heating the water flow. The hot water is then transported to the water inlet pipe 10 through the check valve assembly 9, and then to the spiral temperature regulating channel 104. The hot water transfers heat to the material in the fermentation chamber 101, increasing the temperature of the material in the fermentation chamber 101 and greatly improving the material heating efficiency.Similarly, when it is necessary to cool the material in the fermentation chamber 101, simply disconnect the heating coil 89, then the continuous water supply assembly 7 delivers cold water from the water chamber 102 to the heating assembly 8, then through the check valve assembly 9 to the inlet pipe 10, and then to the spiral temperature regulating channel 104. As the cold water flows through the spiral temperature regulating channel 104, it absorbs the temperature of the material in the fermentation chamber 101, thereby lowering the temperature of the material. Then, hot water is delivered to the return pipe 12, where the heat sink 16 dissipates heat from the hot water, causing its temperature to drop rapidly, and the hot water returning to the inlet water chamber 102 returns to a cold state. In summary, this invention, through the linkage assembly 17, linkage rod 6, continuous water supply assembly 7, heating assembly 8, and spiral temperature regulating channel 104, regulates the temperature within the fermentation chamber 101, thereby controlling the temperature of microbial fermentation, increasing fermentation efficiency, and facilitating later use.
