Abstract
Description
Technical Field
[0001] This invention relates to the field of fertilizer production technology, and specifically to an anti-condensation storage device for fertilizer production and processing. Background Technology
[0002] Fertilizer is a crucial basic material in agricultural production, and the stability of its physical properties directly affects fertilization effectiveness and the efficiency of mechanized operations. During fertilizer production and processing, storage is one of the key processes prone to quality problems. Due to the strong hygroscopicity of fertilizer granules, coupled with the potential for crystal bridge formation due to temperature changes, fertilizer is highly susceptible to clumping in storage silos. Clumped fertilizer not only exhibits reduced flowability but also severely impacts subsequent processes such as bagging and metering, leading to blocked metering valves, inaccurate packaging weights, and even forcing production line shutdowns for cleaning, significantly reducing production efficiency.
[0003] Existing technologies employ various methods to prevent caking. One method involves using chemical additives, such as adding anti-caking agents during fertilizer production to alter granule surface properties and inhibit caking. However, this not only increases raw material costs but also reduces fertilizer purity. Another example is Chinese patent CN216384931U, which discloses a fertilizer production storage device to prevent caking. This device uses vertical and inclined ventilation cylinders inside a storage tank, driven by a geared motor to agitate the fertilizer. However, agitation only delays caking formation; it cannot effectively break up larger clumps that have already formed. Furthermore, the agitation process causes unnecessary mechanical damage to qualified granules, increasing powder content and reducing the final fertilizer quality. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an anti-condensation storage device for fertilizer production and processing, which solves the problem that the quality of fertilizer is affected when storing it to prevent condensation.
[0005] According to an embodiment of the present invention, an anti-condensation storage device for fertilizer production and processing includes:
[0006] The storage bin is used to store fertilizer, and the storage bin has a feed inlet for feeding and a metering valve for discharging.
[0007] The transmission cylinder is coaxially arranged with the storage compartment and rotatably mounted in the storage compartment. Several interception bars are also provided on the outer periphery of the transmission cylinder, and the interception bars are distributed in an array on the outer periphery of the transmission cylinder with respect to the axis of the transmission cylinder.
[0008] The receiving cylinder is coaxially arranged with the storage bin and extends through one side of the storage bin. The receiving cylinder is also located inside the transmission cylinder and has an opening. The transmission cylinder has several guide ports corresponding to each interception bar. The other side of the storage bin is equipped with a transmission component to drive the transmission cylinder to rotate, so that the interception bar intercepts the clumped fertilizer and guides it to the guide port, and then enters the receiving cylinder through the opening.
[0009] Preferably, the transmission component is a first driver.
[0010] Preferably, a receiving bin is provided on the side of the storage bin away from the transmission component, and the receiving cylinder has a connection port that connects to the interior of the receiving bin.
[0011] Preferably, the receiving hopper is equipped with a disintegrating frame for internal rotation, and a third drive is provided on the outside of the receiving hopper, which is connected to the disintegrating frame for transmission.
[0012] Preferably, the bottom of the receiving hopper is equipped with a pipe.
[0013] Preferably, the pipeline connects to the inside of the metering valve.
[0014] Preferably, the receiving cylinder is equipped with a spiral conveyor plate inside, and a second driver is provided at the end of the receiving cylinder, which is connected to the spiral conveyor plate for transmission.
[0015] Preferably, each interception bar is equipped with a guide bar.
[0016] Preferably, the end of the intercepting bar is provided with a guide plate, which extends to the outer surface of the receiving cylinder.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this solution, by setting up a rotating transmission cylinder and its outer periphery with intercepting bars, the material can be actively screened during fertilizer storage. When the transmission cylinder rotates, it effectively intercepts larger clumps that have formed in the storage bin and guides them through the feed inlet into the receiving cylinder, avoiding the problem of clumps clogging the metering valve and affecting packaging accuracy, thus ensuring the stable operation of the production line. Moreover, the intercepting bars only intercept and guide clumped fertilizer, and loose particles that meet the size requirements can leak through the gaps in the intercepting bars without causing additional shearing and squeezing to qualified particles, thereby effectively protecting the integrity of the fertilizer particles. At the same time, the separated clumped fertilizer is collected uniformly in the receiving cylinder for centralized processing, realizing material recycling, reducing waste, and lowering production costs. This solution integrates storage, screening, and separation functions into one unit, reducing the equipment's footprint, achieving a high degree of automation, and low energy consumption.

[0029] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] This invention provides an anti-condensation storage device for fertilizer production and processing, comprising:
[0031] Storage bin 1 is used to store fertilizer, and storage bin 1 has a feed inlet 102 for feeding and a metering valve 101 for discharging.
[0032] The transmission cylinder 2 is coaxially arranged with the storage chamber 1 and rotatably mounted on the storage chamber 1. Several interception bars 202 are also provided on the outer periphery of the transmission cylinder 2. Each interception bar 202 is arranged in an array on the outer periphery of the transmission cylinder 2 with respect to the axis of the transmission cylinder 2.
[0033] The receiving cylinder 3 is coaxially arranged with the storage bin 1 and extends through one side of the storage bin 1. The receiving cylinder 3 is also located inside the transmission cylinder 2 and has an opening 304. The transmission cylinder 2 has several guide ports 205 corresponding to each interception bar 202. The other side of the storage bin 1 is provided with a transmission assembly to drive the transmission cylinder 2 to rotate, so that the interception bar 202 intercepts the clumped fertilizer and guides it to the guide port 205, and then enters the receiving cylinder 3 through the opening 304.
[0034] In this embodiment, as Figures 1 to 4 As shown, storage bin 1 is the main container for containing and storing fertilizer. Its top is equipped with a fertilizer inlet 102, and its bottom is equipped with a metering valve 101 for controlling the discharge flow. Under normal operating conditions, loose, qualified fertilizer is discharged from the metering valve 101 under gravity and enters the subsequent bagging or packaging process. The transmission cylinder 2 has a cylindrical structure, is coaxial with storage bin 1, and is rotatably installed inside storage bin 1. Multiple intercepting grids 202 are fixedly installed on the outer circumferential side wall of the transmission cylinder 2. The intercepting grids 202 extend along the axis of the transmission cylinder 2 and are radially and uniformly distributed around the axis of the transmission cylinder 2. A guide port 205 is provided on the cylinder wall of the transmission cylinder 2 corresponding to the position of each intercepting grid 202, serving as a channel for agglomerated fertilizer to enter the interior of the transmission cylinder 2. The receiving cylinder 3 is also coaxially arranged with the storage chamber 1. One end of it passes through and extends out of the side wall of the storage chamber 1, and the other end is located in the internal cavity of the transmission cylinder 2. An opening 304 is provided on the side wall of the receiving cylinder 3. At the same time, a transmission component is provided on the outside of the storage chamber 1, away from the protruding end of the receiving cylinder 3, for driving the transmission cylinder 2 to rotate around its axis.
[0035] In summary, during fertilizer storage, the transmission assembly is activated, driving the transmission cylinder 2 to rotate slowly inside the storage chamber 1. As the transmission cylinder 2 rotates, the intercepting bars 202 fixed to its outer side also move in a circular motion within the fertilizer material. The intercepting bars 202 have gaps between them, allowing loose, fine, qualified fertilizer particles to pass freely through and remain unobstructed within the storage chamber 1. However, when larger clumps of fertilizer, formed during storage due to moisture or pressure, encounter the intercepting bars 202, they cannot pass through the gaps and are effectively blocked by the intercepting bars 202. As the transmission cylinder 2 continues to rotate, the intercepted clump fertilizer moves along with the interception bar 202 under the thrust and guidance of the interception bar 202. When the interception bar 202 gradually tilts and corresponds to the opening 304, it falls into the receiving cylinder 3 by its own gravity. Since one end of the receiving cylinder 3 extends through the storage bin 1, the clump fertilizer falling into it can be collected and transported to the outside of the storage bin 1, thereby realizing the separation of clump fertilizer from loose fertilizer, ensuring the accuracy and stability of subsequent bagging and metering processes, and the separated clumps can be centrally processed.
[0036] Specifically, such as Figure 1 As shown, the transmission component is the first driver 201. The first driver 201 can be any one of a geared motor or a motor to achieve automated operation and save manpower.
[0037] Specifically, such as Figure 2As shown, a receiving bin 4 is provided on the side of the storage bin 1 away from the transmission component. The receiving cylinder 3 has a connection port 303, which connects to the interior of the receiving bin 4. The receiving bin 4 serves as an independent container for receiving and temporarily storing the separated clump fertilizer. The receiving cylinder 3 has a connection port 303 at one end that penetrates the side wall of the storage bin 1. The connection port 303 is connected to the interior of the receiving bin 4. The clump fertilizer that is intercepted and introduced into the receiving cylinder 3 can enter the receiving bin 4 through the connection port 303 for centralized collection.
[0038] Secondly, a crushing frame 401 is rotatably installed inside the receiving hopper 4, and a third drive 402 is installed on the outside of the receiving hopper 4. The third drive 402 is connected to the crushing frame 401 in a transmission manner. The crushing frame 401 is located inside the receiving hopper 4 and is used to crush the agglomerated fertilizer entering the receiving hopper 4. The third drive 402 can be any type of geared motor or motor. The specific structure of the crushing frame 401 can be a paddle type, hammer type, or toothed roller type, etc. When the agglomerated fertilizer enters the receiving hopper 4, the third drive 402 is activated to drive the crushing frame 401 to rotate inside the receiving hopper 4. The rotating crushing frame 401 applies impact and shearing action to the agglomerated fertilizer, crushing it into loose powder.
[0039] Furthermore, a pipe 5 is provided at the bottom of the receiving hopper 4. The crushed loose fertilizer falls to the bottom of the receiving hopper 4 under gravity and flows out of the receiving hopper 4 through the pipe 5 at the bottom. The pipe 5 can guide the material to a designated collection container or return it to the production system for reuse. Preferably, the pipe 5 is connected to the inside of the metering valve 101. The loose fertilizer crushed by the crushing rack 401 gathers at the bottom of the receiving hopper 4 under gravity and is directly transported back to the metering valve 101 through the pipe 5. After merging with the qualified fertilizer flowing out from the bottom of the storage hopper 1, they enter the subsequent bagging process together.
[0040] Specifically, such as Figure 2 and Figure 4 As shown, the receiving cylinder 3 is equipped with a spiral conveyor plate 301 inside, and a second driver 302 is provided at the end of the receiving cylinder 3. The second driver 302 is connected to the spiral conveyor plate 301 for transmission.
[0041] To achieve forced conveying of agglomerated fertilizer inside the receiving cylinder 3, a spiral conveyor blade 301 is provided inside the receiving cylinder 3 along its axial direction. The spiral conveyor blade 301 can adopt a continuous spiral blade structure, and its outer edge cooperates with the inner wall of the receiving cylinder 3. A second driver 302 is fixedly provided at the end of the receiving cylinder 3. The output end of the second driver 302 is connected to the spiral conveyor blade 301 for driving the spiral conveyor blade 301 to rotate inside the receiving cylinder 3. The second driver 302 can be any one of a geared motor or a motor.
[0042] By activating the second driver 302, the spiral conveyor 301 is driven to rotate inside the receiving cylinder 3. The rotating spiral conveyor 301 generates an axial thrust on the clumped fertilizer falling into the receiving cylinder 3, forcibly conveying it along the inner cavity of the receiving cylinder 3 to the end that passes through the storage bin 1, and finally entering the interior of the receiving bin 4 through the connection port 303. This ensures that the clumped fertilizer can be smoothly and continuously conveyed to the receiving bin 4, avoiding the accumulation and blockage of materials in the receiving cylinder 3.
[0043] Specifically, such as Figure 3 As shown, each interception grid 202 is equipped with a guide bar 204. As the transmission cylinder 2 rotates, the intercepted agglomerated fertilizer begins to move under the thrust and guidance of the interception grid 202. Under the action of the guide bar 204, the intercepted agglomerated fertilizer can be effectively limited and guided, preventing it from rolling laterally on the interception grid 202 or deviating from the predetermined path, ensuring that the agglomerated fertilizer can move stably along the surface of the interception grid 202 towards the transmission cylinder 2. When the agglomerated fertilizer moves to the guide port 205 corresponding to the interception grid 202, under the guidance of the guide bar 204, the agglomerated fertilizer accurately enters the guide port 205.
[0044] Specifically, such as Figure 3 As shown, the end of the interception grid 202 is provided with a guide plate 203, which extends to the outer surface of the receiving cylinder 3. Under the action of the guide plate 203, the intercepted agglomerated fertilizer can be smoothly guided from the interception grid 202 to the outer surface of the receiving cylinder 3, and finally guided to the opening 304.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
