Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a biological fermentation device for industrial fertilizer production. Background Art

[0002] Fertilizer industry production refers to the process of manufacturing fertilizers used to improve soil fertility and promote plant growth through various chemical, physical or biological processes. The main function of fertilizers is to provide plants with essential nutrients such as nitrogen, phosphorus, potassium, etc.

[0003] The patent with publication number CN217052198U relates to a biological fermentation device for agricultural fertilizers, including a fermentation tank body and a support column. Support rods are fixedly connected to both sides of the upper surface of the fermentation tank body, and a cleaning component is connected between the two support rods. A fixed block is fixedly connected to one side of the cleaning component. The fixed block is internally threaded with a limit bolt, and one side of the outer surface of the limit bolt passes through the corresponding position inside the support rod. The inner surface of the sleeve block is slidably connected to the outer surface of the support rod, thereby facilitating the stability of the fixed rod during movement. The device controls the fixed rod to drive the outer surface of the scraper to move back and forth up and down on the inner wall of the fermentation tank body, thereby facilitating the scraping of fertilizer residues attached to the inner wall of the fermentation tank body, making it more effective for workers to clean the interior of the fermentation tank body. However, during the fertilizer fermentation process, the device is prone to problems such as insufficient oxygen obtained by the fertilizer during the fermentation process, resulting in uneven and incomplete fertilizer fermentation, and also causing the fertilizer fermentation time to be too long. Therefore, a biological fermentation device for fertilizer industrialization is proposed to solve the above-mentioned problems. Summary of the Invention

At the same time, more oxygen is provided to the microorganisms, promoting the growth and reproduction of aerobic microorganisms, and accelerating the fermentation process.

[0006] Preferably, the stirring device includes a fixing ring, the inner wall of the rotating shaft is rotatably connected to the rotating rod, the circumferential surface of the rotating rod is fixedly connected to the U-shaped rod, the circumferential surface of the U-shaped rod is fixedly connected to the hook-shaped plate, the circumferential surface of the rotating rod is fixedly connected to the transmission wheel, the circumferential surface of the rotating rod is rotatably connected to the sleeve, the circumferential surface of the sleeve is fixedly connected to the fixing block, the rear part of the fixing block is fixedly connected to the L-shaped plate, the circumferential surface of the sleeve is fixedly connected to the fixing rod, the circumferential surface of the fixing rod is fixedly connected to the scraper, the circumferential surface of the U-shaped rod is fixedly connected to the cutting plate, and the top of the fixing ring is fixedly connected to the U-shaped rod.

It can also exchange the fertilizer in the dead corner of the fermentation barrel with the fertilizer in other parts, making the entire fermentation more uniform and improving the overall fermentation effect. At the same time, it provides more oxygen for the microorganisms, promotes the growth and reproduction of aerobic microorganisms, and accelerates the fermentation process. When the stirring system stops, the fan assembly starts to continue the exchange of air inside the fermentation barrel.

[0009] 2.

[0010] 3. The bio-fermentation device for industrial fertilizer production cooperates with the arc plate, the first protrusion, the support rod, the sliding rod, the second protrusion, the fixed plate, the knocking rod, the knocking block, the rotating plate and the push plate. When a blockage occurs during fertilizer loading, the sliding rod drives the sliding rod downward through spring reset, so that the knocking block knocks on the feed port, causing the feed port to vibrate, and then transmits the vibration to the blocked fertilizer, thereby creating a gap inside the blocked fertilizer and loosening it, thereby causing the fertilizer to slowly fall. At the same time, the movement of the fixed plate drives the movement of the rotating plate, and the movement of the rotating plate drives the movement of the push plate, thereby further unblocking the fertilizer, increasing the falling speed of the fertilizer, and preventing residual fertilizer from clogging and adhering to the inner wall of the feed port.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] See also Figures 1-8 , One embodiment of the present invention is: a bio-fermentation device for industrial fertilizer production, comprising a bottom plate 1, a power bin 2 is fixedly connected to the top of the bottom plate 1, a fermentation barrel 3 is fixedly connected to the top of the power bin 2, a ventilation cover 4 is fixedly connected to the top of the fermentation barrel 3, a funnel cover 5 is fixedly connected to the top of the bottom plate 1, a motor 6 is fixedly connected to the output end of the motor 6, a rotating shaft 7 is fixedly connected to the circumferential surface of the rotating shaft 7, and a stirring blade 8 is fixedly connected to the circumferential surface of the rotating shaft 7.

After the fertilizer is poured into the fermentation barrel 3, the motor 6 is started, the motor 6 starts to drive the rotating shaft 7 to rotate, and the rotating shaft 7 drives the stirring blade 8 to rotate, so that the organic matter in the fertilizer can fully contact with the microorganisms, avoiding the uneven fermentation of some fertilizers, and can also exchange the fertilizer in the dead corner of the fermentation barrel 3 with the fertilizer in other parts, so that the whole fermentation is more uniform, thereby improving the overall fermentation effect. The tripod 9 has a fan assembly 10 on its inner wall. The top of the funnel cover 5 is fixedly connected to an air outlet pipe 11. The circumferential surface of the rotating shaft 7 is fixedly connected to an exhaust blade 12. The inner wall of the fermentation barrel 3 is fixedly connected to a feed port 13. The inner wall of the fermentation barrel 3 is provided with a stirring device 14 for improving the fertilizer mixing effect. The inner wall of the feed port 13 is provided with a dredging device 15 for avoiding fertilizer residue. The circumferential surface of the rotating shaft 7 is rotatably connected to the inner wall of the power compartment 2. The circumferential surface of the rotating shaft 7 is rotatably connected to the inner wall of the fermentation barrel 3. At the same time, during the fermentation process, the rotating shaft 7 rotates to drive the exhaust blades 12 to rotate, so that the exhaust blades 12 will contact the inner wall of the breathable cover 4. The frequency of air exchange inside the fermentation barrel 3 can be controlled by the forward and reverse rotation of the motor 6, so that the gas generated during the fermentation process can be discharged regularly and the external oxygen can be inhaled, thereby providing more oxygen for the microorganisms, promoting the growth and reproduction of aerobic microorganisms, and accelerating the fermentation process. When the stirring system stops, the fan assembly 10 starts to continue the exchange of air inside the fermentation barrel 3.

[0015] The stirring device 14 includes a fixed ring 141, the inner wall of the rotating shaft 7 is rotatably connected to a rotating rod 142, the circumferential surface of the rotating rod 142 is fixedly connected to a U-shaped rod 143, and the circumferential surface of the U-shaped rod 143 is fixedly connected to a hook-shaped plate 144. When stirring, the rotating shaft 7 rotates to drive the rotating rod 142 to rotate, the rotating rod 142 rotates to drive the U-shaped rod 143 to rotate, and the rotating rod 142 rotates to drive the transmission wheel 145 to rotate. During the rotation process, the transmission wheel 145 contacts the fixed ring 141 and generates friction, causing the transmission wheel 145 to rotate. The rotation of 145 drives the rotating rod 142 to rotate, and the rotation of the rotating rod 142 drives the U-shaped rod 143 to rotate, and the rotation of the U-shaped rod 143 drives the hook plate 144 to rotate, so that the fertilizer at the bottom and the top of the fermentation barrel 3 can be exchanged, so that the fluidity of the fertilizer inside the fermentation barrel 3 can be increased, and the fermentation speed and fermentation effect of the fertilizer can be further improved. The circumferential surface of the rotating rod 142 is fixedly connected to the transmission wheel 145, and the circumferential surface of the rotating rod 142 is rotatably connected to the sleeve 146. The circumferential surface of the sleeve 146 is fixedly connected to the fixed block 147. The fixed block The rear part of 147 is fixedly connected to an L-shaped plate 148, the circumferential surface of the sleeve 146 is fixedly connected to a fixing rod 149, the circumferential surface of the fixing rod 149 is fixedly connected to a scraper 1410, the circumferential surface of the U-shaped rod 143 is fixedly connected to a cutting plate 1411, the top of the fixing ring 141 is in contact with the transmission wheel 145, the inner wall of the fixing ring 141 is in contact with the surface of the L-shaped plate 148, the rear part of the scraper 1410 is in contact with the inner wall of the fermentation barrel 3, and when the fermented fertilizer is discharged, the rotating rod 142 rotates to drive the sleeve 146 to rotate. The rotation of the sleeve 146 drives the fixed block 147 to rotate, and the rotation of the fixed block 147 drives the L-shaped plate 148 to rotate, thereby limiting the sleeve 146 so that the sleeve 146 itself will not rotate with the rotation of the rotating rod 142. The rotation of the sleeve 146 drives the fixed rod 149 to rotate, and the rotation of the fixed rod 149 drives the scraper 1410 to rotate. The rotation of the scraper 1410 will contact the inner wall of the fermentation barrel 3, so that the fertilizer attached to the inner wall of the fermentation barrel 3 can be scraped off during the discharge of the fertilizer, avoiding the fertilizer hanging on the wall, resulting in incomplete discharge.

[0016] Working principle: When the fertilizer begins to ferment, the fertilizer is poured into the fermentation barrel 3 through the feed port 13, so that the fertilizer is fermented in the fermentation barrel 3. After the fertilizer is poured into the fermentation barrel 3, the motor 6 is started, and the motor 6 starts to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the stirring blade 8 to rotate, so that the organic matter in the fertilizer can fully contact with the microorganisms, avoiding the uneven fermentation of some fertilizers. It can also exchange the fertilizer in the dead corner of the fermentation barrel 3 with the fertilizer in other parts, making the entire fermentation more uniform and improving the overall fermentation effect. At the same time, during the fermentation process, the rotating shaft 7 rotates and drives the exhaust blade 12 to rotate, so that the exhaust blade 12 will contact the inner wall of the air permeable cover 4. The frequency of air exchange inside the fermentation barrel 3 can be controlled by the forward and reverse rotation of the motor 6, so that the gas generated during the fermentation process can be discharged regularly and the external oxygen can be inhaled, thereby providing more oxygen for the microorganisms, promoting the growth and reproduction of aerobic microorganisms, and accelerating the fermentation process. When the stirring system stops, the fan assembly 10 starts to continue the exchange of air inside the fermentation barrel 3.

[0017] During stirring, the rotation of the rotating shaft 7 drives the rotating rod 142 to rotate, the rotation of the rotating rod 142 drives the U-shaped rod 143 to rotate, and the rotation of the rotating rod 142 drives the transmission wheel 145 to rotate. During the rotation, the transmission wheel 145 contacts the fixed ring 141 and generates friction, so that the transmission wheel 145 rotates, and the rotation of the transmission wheel 145 drives the rotating rod 142 to rotate. The rotation of the rotating rod 142 drives the U-shaped rod 143 to rotate, and the rotation of the U-shaped rod 143 drives the hook plate 144 to rotate, so that the fertilizer at the bottom and the top of the fermentation barrel 3 can be exchanged, so that the fluidity of the fertilizer inside the fermentation barrel 3 can be increased, thereby further improving the fermentation speed and fermentation efficiency of the fertilizer. At the same time, when the fermented fertilizer is discharged, the rotating rod 142 rotates to drive the sleeve 146 to rotate, the rotation of the sleeve 146 drives the fixed block 147 to rotate, and the rotation of the fixed block 147 drives the L-shaped plate 148 to rotate, thereby limiting the sleeve 146 so that the sleeve 146 itself does not rotate with the rotation of the rotating rod 142, and the rotation of the sleeve 146 drives the fixed rod 149 to rotate, and the rotation of the fixed rod 149 drives the scraper 1410 to rotate. The scraper 1410 rotates and contacts the inner wall of the fermentation barrel 3, so that the fertilizer attached to the inner wall of the fermentation barrel 3 can be scraped off during the discharge of the fertilizer, thereby avoiding the fertilizer hanging on the wall, resulting in incomplete discharge.

[0018] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the dredging device 15 includes a curved plate 151, which is fixedly connected to the inner wall of the scraper 1410. The top of the curved plate 151 is fixedly connected to a protrusion 152, and the bottom of the curved plate 151 is fixedly connected to a support rod 153. The inner wall of the feed port 13 is slidably connected to a sliding rod 154 through a spring, and the bottom of the sliding rod 154 is fixedly connected to a protrusion 2 155. When a blockage occurs during fertilizer loading, the motor 6 is started to make the fixed rod 149 perform a turnover motion to drive the curved plate 151 to rotate. The rotation of the arc plate 151 drives the protrusion 152 to rotate. The protrusion 152 contacts the protrusion 2 155 during the rotation and generates an extrusion force on the protrusion 2 155, forcing the protrusion 2 155 to move upward. The upward movement of the protrusion 2 155 drives the sliding rod 154 to move. The movement of the sliding rod 154 drives the spring to stretch. The movement of the sliding rod 154 drives the fixed plate 156 to move upward. The upward movement of the fixed plate 156 drives the knocking rod 157 to move upward. The upward movement of the knocking rod 157 drives the knocking block 158 to move upward. When the protrusion 152 and the protrusion 2 155 are not in contact with each other, The sliding rod 154 is driven to move downward by the spring return, so that the knocking block 158 can knock the feed port 13, causing the feed port 13 to vibrate, and then transmit the vibration to the blocked fertilizer, so that a gap can be generated inside the blocked fertilizer and loosen it, so that the fertilizer slowly falls down, and it vibrates multiple times through multiple protrusions 152. The circumferential surface of the sliding rod 154 is fixedly connected to the fixed plate 156, and the inner wall of the fixed plate 156 is fixedly connected to the knocking rod 157. The bottom of the knocking rod 157 is fixedly connected to the knocking block 158, and the fixed plate 15 6 is rotatably connected to a rotating plate 159 at the front, and a push plate 1510 is rotatably connected to the inner wall of the rotating plate 159. The right side of the support rod 153 is fixedly connected to the circumferential surface of the fixed rod 149. The bottom of the knocking block 158 contacts the inner wall of the feed port 13, and the bottom of the push plate 1510 is slidably connected to the inner wall of the feed port 13. At the same time, the movement of the fixed plate 156 drives the rotating plate 159 to move, and the movement of the rotating plate 159 drives the push plate 1510 to move, thereby further dredging the fertilizer, increasing the falling speed of the fertilizer, and preventing the residual fertilizer from clogging and adhering to the inner wall of the feed port 13.

[0019] Working principle: When a blockage occurs during fertilizer loading, the motor 6 is started to make the fixed rod 149 rotate to drive the arc plate 151 to rotate. The rotation of the arc plate 151 drives the protrusion 152 to rotate. The protrusion 152 contacts the protrusion 2 155 during the rotation and generates an extrusion force on the protrusion 2 155, forcing the protrusion 2 155 to move upward. The upward movement of the protrusion 2 155 drives the sliding rod 154 to move. The movement of the sliding rod 154 drives the spring to stretch. The movement of the sliding rod 154 drives the fixed plate 156 to move upward. The upward movement of the fixed plate 156 drives the knocking rod 157 to move upward. The upward movement of the knocking rod 157 drives the knocking block 158 to move upward. When the first 152 and the second protrusion 155 are not in contact with each other, the sliding rod 154 is driven to move downward by the spring reset, so that the knocking block 158 can knock on the feed port 13, causing the feed port 13 to vibrate, and then transmit the vibration to the blocked fertilizer, so that a gap can be generated inside the blocked fertilizer, thereby loosening it, and allowing the fertilizer to slowly fall. It is vibrated multiple times through multiple protrusions 152, and at the same time, the fixed plate 156 moves to drive the rotating plate 159 to move, and the rotating plate 159 moves to drive the push plate 1510 to move, so as to further clear the fertilizer, increase the falling speed of the fertilizer, and prevent residual fertilizer from clogging and adhering to the inner wall of the feed port 13.
