Description

Technical Field

[0001] This invention relates to the field of fertilizer conveying, and in particular to a conveying device for fertilizer production. Background Technology

[0002] Organic materials are mostly processed organic fertilizers (such as livestock and poultry manure, organic matter from urban waste, sludge, straw, sawdust, food processing waste, etc.) and substances containing organic matter (peat, weathered coal, lignite, humic acid, etc.). Some also contain added microbial agents and growth-stimulating substances, which are called organic active fertilizers or biological slow-release fertilizers.

[0003] A patent with publication number CN116412655A discloses a cooling and conveying device for organic fertilizer production and its usage method. The device includes a conveyor body with a circulation assembly on its outer wall. A blower assembly sends gas into the conveyor body cavity to heat and dry the organic fertilizer. A vacuum pump sends the gas from the conveyor body cavity into a heat exchange box, where coolant is injected. The vacuum pump then sends heated gas into the heat exchange box to heat the coolant, raising the temperature of the coolant in the heat exchange tubes. After heating, the coolant is pumped by a water pump to a blower box to heat the gas entering the blower box. The heated gas is then sent into the conveyor body cavity by a fan assembly for drying. This increases the initial temperature of the airflow used for drying the organic fertilizer, improving the drying effect and preventing the organic fertilizer from sticking due to excessive residual heat during packaging. It also improves the utilization rate of residual heat in the organic fertilizer.

[0004] Currently, there are the following problems when transporting newly produced organic fertilizer granules: During the production of organic fertilizer, most of it is produced in granular form. After granulation, the organic fertilizer needs to undergo cooling and drying. This is because fertilizer granules produced at excessively high temperatures have higher chemical activity, which can easily cause them to lose their fertilizer effectiveness. Rapid cooling cannot prioritize drying the organic fertilizer, causing the granules to stick together. Therefore, the organic fertilizer must be dried first. However, excessive accumulation of fertilizer granules can lead to slow drying and poor effect in the center of the granules. They are also prone to sticking together, which not only causes the bags to stick during packaging but also creates inconvenience for later use. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the fact that in the prior art, when drying organic fertilizer, the surface of the fertilizer particles piled together is dried first, but the fertilizer particles in the center of the fertilizer particles cannot be effectively dried. As time goes by, the moist organic fertilizer will stick together, which not only makes it easy to stick to the bag during packaging, but also causes inconvenience in later use. Therefore, the present invention provides a conveying device for fertilizer production.

[0006] To solve the above-mentioned technical problems, the present invention provides a conveying device for fertilizer production, including a stirring conveying cylinder and an arc-shaped fitting cylinder movably sleeved on the outer surface of the stirring conveying cylinder; the outer surface of the stirring conveying cylinder is evenly provided with a permeable mesh, the inner wall of the arc-shaped fitting cylinder is movably sleeved on the outer edge of the permeable mesh, and the two side surfaces of the arc-shaped fitting cylinder are symmetrically provided with supporting rollers that movably overlap the outer surface of the stirring conveying cylinder; an air inlet pipe and an air outlet pipe are respectively fixedly installed on the two side surfaces and the bottom surface of the arc-shaped fitting cylinder, and one end of the air outlet pipe is fixedly connected to...

[0007] In one embodiment of the present invention, multiple sets of chemical blocking strips are evenly distributed on the inner wall of the stirring conveyor cylinder, and multiple sets of limiting track strips are fixedly connected to the outer surface of the stirring conveyor cylinder.

[0008] In one embodiment of the present invention, an arc-shaped overlapping plate is provided on the outer surface of the stirring conveyor cylinder, a limiting track bar is fixedly connected to the inner wall of the arc-shaped overlapping plate, the outer surface of the limiting track bar is movably sleeved on the inner wall of the limiting track bar, and a groove is provided on the bottom surface of the arc-shaped overlapping plate.

[0009] In one embodiment of the present invention, a second motor is fixedly installed on the bottom surface of the arc-shaped overlapping plate, a transmission disk is fixedly connected to the output end of the second motor, the outer surface of the transmission disk is located inside the slot and movably overlaps the outer surface of the slot, and a support leg is fixedly installed on the bottom outer surface of the arc-shaped overlapping plate.

[0010] In one embodiment of the present invention, a flow guiding hose is fixedly connected to one end of the stirring conveying cylinder, a material collecting sleeve is fixedly connected to the other end of the flow guiding hose, a baffle is fixedly connected to the inner wall of the material collecting sleeve, a closing cover is provided on the top surface of the material collecting sleeve, and a motor is fixedly installed on the outer surface of the closing cover.

[0011] In one embodiment of the present invention, a transmission disc is fixedly connected to the output end of the motor and is movably attached to the top surface of the baffle. The transmission disc and the outer surface of the baffle are provided with material dropping holes.

[0012] In one embodiment of the present invention, a plurality of blocking strips are fixedly installed on the top surface of the transmission disc, and a support frame is fixedly installed on the outer surface of the collecting sleeve.

[0013] In one embodiment of the present invention, a support base plate is fixedly installed on the outer surface of the support frame, and a hydraulic rod is fixedly installed on the top surface of the support base plate and at one side edge. An arc-shaped lifting plate is fixedly connected to the output end of the hydraulic rod, and limit baffles are provided on both sides of the arc-shaped lifting plate.

[0014] In one embodiment of the present invention, a lifting plate is oscillatingly connected to the top surface of the supporting base plate, and an R-shaped rounded corner is provided on one side surface of the lifting plate. The outer surface of the R-shaped rounded corner is movably overlapped with the top surface of the hydraulic rod, and the inner wall of the limiting baffle is movably attached to the two side edges of the lifting plate.

[0015] In one embodiment of the present invention, the top surface of the lifting plate is fixedly installed on the bottom surface of the support leg and the heat preservation box, a support sleeve is fixedly installed on the other side surface of the support base plate, and a drainage sleeve that is movably sleeved on the outer surface of the tail end of the stirring conveyor is fixedly connected to the outer surface of the support sleeve.

[0016] Compared with the prior art, the above-described technical solution of the present invention has the following advantages:

[0017] The fertilizer production conveying equipment described in this invention uses an arc-shaped bonding plate that slides onto the outer surface of a stirring conveying cylinder, allowing the exhaust pipe to contact the permeable mesh on the surface of the stirring conveying cylinder. By using the arc-shaped bonding plate to reduce the permeable area of ​​the permeable mesh, the gas absorption of the exhaust pipe can directly absorb gas from the bottom and center of the fertilizer particles, thereby absorbing the moisture inside the fertilizer particles. After the gas inside the fertilizer particles is absorbed, the hot air on the outer surface of the fertilizer particles will quickly pass through the fertilizer particles. The rapid flow of hot air can accelerate the absorption of moisture on the surface of the fertilizer particles and achieve the effect of drying.

[0018] The fertilizer production conveying equipment of this invention involves the absorption of gas into a water vapor filter box, where the water vapor inside the hot gas is filtered. Then, fertilizer powder in the gas is filtered through a sieve plate. The hot gas is then pushed out through an exhaust port, impacting the outer surface of a push plate, which in turn drives a rotating rod to rotate on the inner surface of an insulation box. As the rod rotates, the heating rod on its outer surface comes into contact with the gas, thus reheating the filtered gas. Simultaneously, the oscillation of the push plate agitates the hot gas, mixing it with low-temperature gas. The dried gas then re-enters the agitating conveying cylinder through an inlet pipe, maintaining a dry environment inside the cylinder. With the intake of the exhaust pipe, the dried gas quickly passes through the fertilizer particles for further drying, achieving a secondary drying process for the absorbed gas.

[0019] The fertilizer production conveying equipment described in this invention involves a motor driving a transmission disc to rotate after fertilizer granules enter the tumbling conveyor cylinder. This transmission disc pushes a second limiting track on the inner wall of a first limiting track, causing the tumbling conveyor cylinder to rotate. Meanwhile, a separation blocking strip on the inner wall of the tumbling conveyor cylinder blocks the flow of fertilizer granules, reducing their speed. The blocking strip also allows the fertilizer granules to be easily tumbled, effectively dispersing granules at the bottom layer. The tumbling action gradually disperses any granules that are stuck together, increasing the contact area and range between the fertilizer granules and the drying hot air, thus ensuring effective drying of the fertilizer granules.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0029] Reference Figure 1 - Figure 2 and Figure 6As shown, a conveying device for fertilizer production according to the present invention includes a stirring conveying cylinder 15 and an arc-shaped fitting cylinder 1410 movably sleeved on the outer surface of the stirring conveying cylinder 15. A permeable mesh 152 is evenly distributed on the outer surface of the stirring conveying cylinder 15. The inner wall of the arc-shaped fitting cylinder 1410 is movably sleeved on the outer edge of the permeable mesh 152. Support rollers 1411, movably overlapping the outer surface of the stirring conveying cylinder 15, are symmetrically arranged on both sides of the arc-shaped fitting cylinder 1410. An air inlet pipe 149 and an exhaust pipe 147 are fixedly installed on the two sides and the bottom surface of the arc-shaped fitting cylinder 1410, respectively. One end of the exhaust pipe 147 is fixedly connected to a movably fitted cylinder 1410. An arc-shaped bonding plate 148 is fixedly connected to the bottom outer surface of the stirring conveyor cylinder 15. An insulated box 14 is fixedly connected to the bottom surface of the air inlet pipe 149 and the exhaust pipe 147. A water vapor filter box 141 is fixedly installed on the bottom inner wall of the insulated box 14 and is located at the other end of the exhaust pipe 147. A sieve plate 142 is fixedly connected to the inner wall of the water vapor filter box 141 and is located on the outer surface of the exhaust pipe 147. An exhaust hole 143 is provided on both sides of the water vapor filter box 141 and at the top edge. Rotating rods 144 are symmetrically arranged on both sides of the inner wall of the insulated box 14. Heating rods 146 and push plates 145 are evenly distributed on the outer surface of the rotating rods 144.

[0030] As the stirring conveyor cylinder 15 rotates, the supporting rollers 1411 on the outer surface of the arc-shaped bonding cylinder 1410 keep the stirring conveyor cylinder 15 at the center of the arc-shaped bonding cylinder 1410, reducing the friction between the stirring conveyor cylinder 15 and the arc-shaped bonding cylinder 1410. At this time, the arc-shaped bonding plate 148 slides and adheres to the outer surface of the stirring conveyor cylinder 15, so that the exhaust pipe 147 contacts the breathable net 152 on the surface of the stirring conveyor cylinder 15. The arc-shaped bonding plate 148 reduces the air permeability area of ​​the breathable net 152. At this time, the gas absorption of the exhaust pipe 147 can directly absorb the gas at the bottom and center of the fertilizer granules, thereby absorbing the water vapor inside the fertilizer granules. After the gas inside the fertilizer granules is absorbed, the hot air on the outer surface of the fertilizer granules will quickly pass through the fertilizer granules. The rapid flow of hot air can accelerate the absorption of water vapor on the surface of the fertilizer granules and the drying effect.

[0031] The absorbed gas enters the interior of the water vapor filter box 141, where the water vapor inside the hot gas is filtered. Then, some fertilizer powder in the gas is filtered through the sieve plate 142. At this point, the hot gas is pushed out through the exhaust port 143. The pushed-out hot gas impacts the outer surface of the push plate 145, thereby causing the rotating rod 144 to rotate on the inner surface of the insulation box 14. As the rotating rod 144 rotates, the heating rod 146 on its outer surface is activated. The gas comes into contact with the filtered water vapor and undergoes secondary heating. At the same time, the oscillation of the push plate 145 agitates the hot gas, mixing it with the low-temperature gas. The dried gas then re-enters the agitating conveyor cylinder 15 through the inlet pipe 149, maintaining a dry environment inside the cylinder. Under the suction of the exhaust pipe 147, the dried gas quickly passes through the fertilizer granules for further drying, achieving a secondary drying process for the absorbed gas.

[0032] Reference Figure 1 - Figure 2 As shown, a conveying device for fertilizer production according to the present invention includes a plurality of chemical blocking strips 151 evenly distributed on the inner wall of a stirring conveying cylinder 15. A plurality of limiting track strips 153 are fixedly connected to the outer surface of the stirring conveying cylinder 15. An arc-shaped overlapping plate 131 is provided on the outer surface of the stirring conveying cylinder 15. A limiting track strip 132 is fixedly connected to the inner wall of the arc-shaped overlapping plate 131. The outer surface of the limiting track strip 153 is movably sleeved on the inner wall of the limiting track strip 132. A slot 133 is opened on the bottom surface of the arc-shaped overlapping plate 131. A motor 134 is fixedly installed on the bottom surface of the arc-shaped overlapping plate 131. A transmission disc is fixedly connected to the output end of the motor 134. The outer surface of the transmission disc is located inside the slot 133 and movably overlaps the outer surface of the slot 133. A support leg 13 is fixedly installed on the bottom outer surface of the arc-shaped overlapping plate 131.

[0033] When fertilizer granules enter the mixing and conveying cylinder 15, the motor 134 rotates the transmission disc, which in turn pushes the limiting track 153 on the inner wall of the limiting track 132, causing the mixing and conveying cylinder 15 to rotate. At this time, the separation blocking strip 151 on the inner wall of the mixing and conveying cylinder 15 blocks the fertilizer granules inside, thereby reducing the flow speed of the fertilizer granules. Moreover, the blocking strip 151 allows the fertilizer granules to be simply tumbled up and down, so that the fertilizer granules at the bottom can be effectively tumbled out. The tumbling fertilizer granules can gradually disperse the fertilizer granules that are stuck together under impact, thereby increasing the contact area and range between the fertilizer granules and the drying hot air, so that the fertilizer granules can be effectively dried.

[0034] Reference Figure 3 As shown, a conveying device for fertilizer production according to the present invention includes a diversion hose 118 fixedly connected to one end of a stirring conveying cylinder 15, a collecting sleeve 111 fixedly connected to the other end of the diversion hose 118, a baffle 116 fixedly connected to the inner wall of the collecting sleeve 111, a closing cover 112 provided on the top surface of the collecting sleeve 111, a motor 113 fixedly installed on the outer surface of the closing cover 112, a transmission disc 114 movably overlapping the top surface of the baffle 116 fixedly connected to the output end of the motor 113, a material drop hole 117 opened on the outer surface of the transmission disc 114 and the baffle 116, multiple sets of blocking strips 115 fixedly installed on the top surface of the transmission disc 114, and a support frame 11 fixedly installed on the outer surface of the collecting sleeve 111.

[0035] The freshly processed fertilizer granules are guided into the collection sleeve 111, causing them to accumulate on the top surface of the transmission disc 114. Simultaneously, the motor 113 rotates the transmission disc 114. Each time the discharge hole 117 on the outer surface of the transmission disc 114 aligns with the discharge hole 117 on the outer surface of the baffle 116, the fertilizer granules on the top surface of the transmission disc 114 pass through the discharge hole 117 and enter the agitating conveyor cylinder 15 via the guide hose 118. As the transmission disc 114 rotates, the baffle bar 115 on the top surface blocks the fertilizer granules accumulated on its surface. The granules are agitated and gradually and evenly pass through the discharge hole 117 into the drainage hose 118. When the discharge hole 117 on the outer surface of the transmission disc 114 coincides with the discharge hole 117 on the surface of the baffle 116, the fertilizer granules can be quantitatively discharged and fall. The transmission disc 114 continuously agitates the fertilizer granules at the bottom layer, keeping the fertilizer granules in a flowing state. This effectively prevents the fertilizer granules from becoming clogged after misalignment in the discharge hole 117, and avoids the accumulation of fertilizer granules caused by excessive discharge at one time.

[0036] Reference Figure 1 - Figure 2 and Figure 4 As shown, in a conveying device for fertilizer production according to the present invention, a support base plate 12 is fixedly installed on the outer surface of a support frame 11. A hydraulic rod 123 is fixedly installed on the top surface of the support base plate 12 and at one edge position. An arc-shaped lifting plate 124 is fixedly connected to the output end of the hydraulic rod 123. Limiting baffles 125 are provided on both sides of the arc-shaped lifting plate 124. A lifting plate 121 is oscillatingly connected to the top surface of the support base plate 12. An R-shaped rounded corner is provided on one side surface of the lifting plate 121. 122, the outer surface of the R-shaped rounded corner 122 is movably overlapped with the top surface of the hydraulic rod 123, the inner wall of the limiting baffle 125 is movably attached to the two side edges of the lifting plate 121, the top surface of the lifting plate 121 is fixedly installed on the bottom surface of the support leg 13 and the heat preservation box 14, the other side surface of the support base plate 12 is fixedly installed with the support sleeve 126, and the outer surface of the support sleeve 126 is fixedly connected with the drainage sleeve 127 which is movably sleeved on the outer surface of the tail end of the stirring conveying cylinder 15.

[0037] Based on the size and moisture content of the fertilizer particles, the hydraulic rod 123 pushes the arc-shaped lifting plate 124, causing the surface of the arc-shaped lifting plate 124 to adhere to and lift the surface of the R-shaped rounded corner 122. As the arc-shaped lifting plate 124 slides continuously, the lifting plate 121 is lifted, thereby changing the tilt angle of the stirring conveyor cylinder 15 and altering the flow speed of the fertilizer particles inside the stirring conveyor cylinder 15. This achieves the effect of adjusting the angle of the lifting plate 121 using the arc-shaped lifting plate 124, allowing the swing angle of the stirring conveyor cylinder 15 to be adjusted according to the moisture content of the fertilizer particles, thus changing the flow speed of the fertilizer particles.

[0038] This invention discloses a conveying device for fertilizer production. Freshly processed fertilizer granules are guided into the interior of a collecting sleeve 111, causing them to accumulate on the top surface of a transmission disc 114. Simultaneously, a motor 113 rotates the transmission disc 114. Each time the discharge hole 117 on the outer surface of the transmission disc 114 coincides with the discharge hole 117 on the outer surface of the baffle 116, the fertilizer granules on the top surface of the transmission disc 114 pass through the discharge hole 117 and enter the agitation conveying cylinder 15 through a guiding hose 118. As the transmission disc 114 rotates, the blocking strip 115 on its top surface... The fertilizer granules piled on the surface are agitated so that they can gradually and evenly pass through the discharge hole 117 and enter the drainage hose 118. When the discharge hole 117 on the outer surface of the transmission disc 114 coincides with the discharge hole 117 on the surface of the baffle 116, the fertilizer granules can be quantitatively discharged and fall. Moreover, the transmission disc 114 continuously agitates the bottom layer of fertilizer granules, keeping the fertilizer granules in a flowing state. This effectively prevents the fertilizer granules from becoming blocked after misalignment in the discharge hole 117, and avoids the accumulation of fertilizer granules caused by excessive discharge at one time.

[0039] When fertilizer granules enter the mixing and conveying cylinder 15, the motor 134 rotates the transmission disc, which pushes the limit track 153 on the inner wall of the limit track 132, causing the mixing and conveying cylinder 15 to rotate. At this time, the separation blocking strip 151 on the inner wall of the mixing and conveying cylinder 15 blocks the fertilizer granules inside, thereby reducing the flow speed of the fertilizer granules. Moreover, the blocking strip 151 allows the fertilizer granules to be simply tumbled up and down, so that the fertilizer granules at the bottom can be effectively tumbled out. The tumbling fertilizer granules can gradually disperse the fertilizer granules that are stuck together under impact, thereby increasing the contact area and range between the fertilizer granules and the drying hot air, so that the fertilizer granules can be effectively dried.

[0040] As the stirring conveyor cylinder 15 rotates, the supporting rollers 1411 on the outer surface of the arc-shaped bonding cylinder 1410 keep the stirring conveyor cylinder 15 at the center of the arc-shaped bonding cylinder 1410, reducing the friction between the stirring conveyor cylinder 15 and the arc-shaped bonding cylinder 1410. At this time, the arc-shaped bonding plate 148 slides and adheres to the outer surface of the stirring conveyor cylinder 15, so that the exhaust pipe 147 contacts the breathable net 152 on the surface of the stirring conveyor cylinder 15. The arc-shaped bonding plate 148 reduces the air permeability area of ​​the breathable net 152. At this time, the gas absorption of the exhaust pipe 147 can directly absorb the gas at the bottom and center of the fertilizer granules, thereby absorbing the water vapor inside the fertilizer granules. After the gas inside the fertilizer granules is absorbed, the hot air on the outer surface of the fertilizer granules will quickly pass through the fertilizer granules. The rapid flow of hot air can accelerate the absorption of water vapor on the surface of the fertilizer granules and the drying effect.

[0041] The absorbed gas enters the interior of the sieve plate 142, where the sieve plate 142 filters out water vapor and some fertilizer powder. The hot gas is then pushed out through the exhaust port 143. This pushed-out hot gas impacts the outer surface of the push plate 145, causing the rotating rod 144 to rotate on the inner surface of the insulation box 14. As the rotating rod 144 rotates, the heating rod 146 on its outer surface comes into contact with the gas, further filtering out water vapor. The hot gas undergoes secondary heating treatment, and the oscillation of the push plate 145 agitates the hot gas, mixing it with the low-temperature gas. The dried gas then re-enters the agitation conveyor cylinder 15 through the inlet pipe 149, maintaining a dry environment inside the cylinder. Under the suction of the exhaust pipe 147, the dried gas quickly passes through the fertilizer granules for drying, achieving secondary drying of the absorbed gas. The dried fertilizer granules are then discharged through the guide sleeve 127.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
