Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer production, and particularly relates to a fermentation device for seaweed fertilizer. Background Art

[0002] Seaweed fertilizer is a kind of bio-organic fertilizer with large marine algae as the main raw material, which can be extracted or fermented by physical, chemical or biological methods, rich in a variety of bioactive substances and nutrient elements, and is used to promote plant growth, improve crop yield and quality, and enhance plant stress resistance.

[0003] The production of seaweed fertilizer is a complex and delicate process, in which the fermentation link is crucial. Usually, the crushed seaweed, fermentation broth and cultured microorganisms are introduced into the fermentation tank, and the stirring device of the fermentation tank is started to make the materials mix evenly to create a suitable environment for the growth of microorganisms. As the fermentation progresses, the microorganisms metabolize a large amount of nutrients and produce various metabolites, and at the same time release gases such as carbon dioxide. These gases form bubbles in the fermentation broth, and substances such as seaweed components, microbial metabolites and microbial cells in the fermentation broth have certain surface activity, and they adsorb on the surface of the bubbles to form a stable liquid film, so that the bubbles are not easy to break. Especially when the stirring intensity is too high or the ventilation volume is too high, a large number of foams gradually gather.

[0004] Due to the relatively high pressure inside the fermentation tank and the relatively low external pressure, this pressure difference will cause the gas to flow out of the tank, and will drive the foam on the surface of the fermentation broth to be discharged together. The foam may carry fragmented seaweed. As the gas is discharged, these seaweed-containing foams enter the outlet pipeline. When the foam breaks in the pipeline, the seaweed fragments will adhere to the inner wall of the pipeline and gradually accumulate and agglomerate, resulting in the blockage of the outlet pipeline. The air pressure in the fermentation tank will gradually increase, and over time, the original pressure balance will be broken, resulting in a decrease in the dissolved oxygen content in the fermentation broth and a reduction in the metabolic efficiency, thereby affecting the fermentation process of seaweed. Summary of the Invention

[0005] Technical Problems to be Solved Aiming at the above-mentioned disadvantages of the prior art, the present invention provides a fermentation device for seaweed fertilizer, which can effectively solve the problem that in the prior art, when the foam containing seaweed is discharged outward with the gas during the fermentation process of seaweed in the fermentation tank, the foam will break in the outlet pipeline, and the seaweed fragments gradually accumulated on the inner wall of the pipeline are likely to cause the blockage of the outlet pipeline, and the air pressure in the fermentation tank will gradually increase.

[0006] Technical Solutions To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a seaweed fertilizer fermentation device, including a fermentation tank. An air inlet pipe is provided on the fermentation tank. An air outlet pipe is detachably installed on the tank wall of the fermentation tank. An air outlet valve is installed at the air outlet end of the air outlet pipe. A cleaning component for self-cleaning seaweed residues is arranged in the inner cavity of the air outlet pipe. The cleaning component includes a horizontal shaft rod coinciding with the axis of the air outlet pipe. A number of elastic ropes are arranged on the horizontal shaft rod. A moving ring is arranged at one end of the horizontal shaft rod away from the fermentation tank. A scraping strip is connected to the outer wall of the moving ring.

[0007] Further, traveling wheels are arranged at both ends of the horizontal shaft rod. A number of traveling wheels are arranged in an array centered on the axis of the horizontal shaft rod. A connecting rod is arranged between the traveling wheel and the horizontal shaft rod.

[0008] Further, a positioning block is fixedly installed at one end of the horizontal shaft rod close to the fermentation tank. The elastic ropes are connected to the outer wall of the positioning block in an array. One end of the elastic rope away from the positioning block is detachably connected to the inner wall of the fermentation tank.

[0009] Further, the outer diameter of the moving ring is the same as the inner diameter of the air outlet pipe. The cross section of the scraping strip is triangular. The surface of the scraping strip close to the inner wall of the air outlet pipe is an inclined surface. A hemispherical block is fixedly sleeved on the outer side of the horizontal shaft rod. The hemispherical block is located inside the scraping strip. The outer wall of the hemispherical block is connected to the outer wall of the moving ring through a fixing rod.

[0010] Further, a receiving component for collecting seaweed residues is arranged outside the cleaning component. The receiving component includes a receiving bottle that can be threadedly installed at the bottom of the air outlet pipe. A rotating cylinder is rotatably installed on the outer side of the horizontal shaft rod through a bearing. The rotating cylinder is located between the positioning block and the hemispherical block. A connecting ring is fixedly installed on the outer wall of the rotating cylinder. A number of fan blades are arranged on the outer wall of the connecting ring in an array centered on its axis.

[0011] Further, the side wall of the rotating cylinder is rotatably connected to the outer wall of the hemispherical block. An arc-shaped scraping piece is integrally formed and connected to the outer wall of the rotating cylinder. The inner wall of the arc-shaped scraping piece is attached to the outer wall of the hemispherical block.

[0012] Further, through holes for seaweed residues to pass through are penetrated in the wall body of the air outlet pipe. A friction piece is placed in the receiving bottle. The friction piece is a sponge piece impregnated with moisture. The friction piece is attached to the inner wall of the receiving bottle.

[0013] Further, an auxiliary component is provided on one side of the horizontal shaft rod close to the fermentation tank.

[0014] Further, a moving rod is arranged inside the driving cylinder, and the diameter of the moving rod is the same as the inner diameter of the driving cylinder. An inclined groove is formed on the outer wall of the moving rod, and the overall length of the inclined groove is half of the circumference of the circumferential surface of the moving rod. A convex rod is integrally formed and connected to the inner wall of the driving cylinder, and one end of the convex rod is located inside the inclined groove.

[0015] Further, one end of the moving rod away from the driving cylinder is connected with a limiting disc. A resetting member is connected between the limiting disc and the outer wall of the filter screen, and the resetting member is sleeved outside the moving rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, when the air outlet valve is opened, an air pressure difference is generated inside and outside the fermentation tank. The air flow pushes the horizontal shaft rod to move towards the air outlet valve side. The thrust of the air flow is greater than the elasticity of the elastic rope, causing it to stretch. When the exhaust pressure is constant, under the resetting action of the elastic rope, the moving ring is driven to quickly move back towards the fermentation tank side, scraping off the residual seaweed fragments on the inner wall of the air outlet pipe. The seaweed fragments scraped by the top of the moving ring slide to the bottom of the scraping bar under the action of gravity, facilitating subsequent collection. No additional power source is required, avoiding blockage of the air outlet pipe and reducing the number of times of disassembling the air outlet pipe for manual cleaning.

Specific embodiments

[0020] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Embodiment 1, refer to Figures 1-5, which is the first embodiment of the present invention, provides a seaweed fertilizer fermentation device, including a fermentation tank 1 with a stirring mechanism, an air inlet pipe 2 is arranged on the fermentation tank 1, an air outlet pipe 3 is detachably installed on the tank wall of the fermentation tank 1 through a sealing flange, an air outlet valve 4 is installed at the air outlet end of the air outlet pipe 3, and a cleaning component 5 for self-cleaning seaweed debris is installed in the inner cavity of the air outlet pipe 3; a receiving component 6 for collecting seaweed debris is installed on the outer side of the cleaning component 5, and the receiving component 6 can use a water jet to flush the seaweed debris out of the air outlet pipe 3, and collect these debris through a water collecting tank, and the water can be recycled, but long-term use of the water jet may lead to The auxiliary component 7 is installed on the side of the horizontal shaft 51 close to the fermenter 1. The auxiliary component 7 can be a rotating cutting blade group installed on the inner side of the exhaust port of the fermenter 1. Under the action of the gas flow in the outlet pipe 3, the blade group rotates. When the seaweed fragments approach with the gas flow, the rotating blades can cut the large pieces of seaweed fragments into pieces, making them smaller in size and easier to be discharged from the outlet pipe 3 with the air flow, which greatly reduces the possibility of the seaweed fragments accumulating and agglomerating in the pipeline, thereby ensuring the smooth flow of the outlet pipe 3 and ensuring that the gas in the fermenter 1 can be discharged normally.

[0023] Specifically, during the stirring or fermentation process, the vigorous metabolism of microorganisms will continue to produce gases such as carbon dioxide. As the fermentation time progresses, the gas in the tank continues to accumulate. When the pressure reaches the upper limit of the pressure set by the fermentation tank 1 for safety (for example, 1.1-1.2 times higher than the normal working pressure), high-pressure exhaust is required to maintain the pressure in the tank stable and ensure a suitable fermentation environment. In this case, exhaust is usually performed multiple times at intervals, because the gas production of microbial metabolism is relatively stable within a certain range, and exhaust is performed once every period of time when the upper limit of the pressure is reached. Each time the outlet valve 4 is opened, the pressure difference will cause the gas to flow out of the tank, and will drive the foam on the surface of the fermentation liquid to be discharged together. The foam may contain broken seaweed. As the gas is discharged, these foams with seaweed enter the outlet pipe 3. When the foam breaks in the pipe, the seaweed fragments will adhere to the inner wall of the pipe, gradually accumulate and agglomerate, causing the outlet pipe 3 to be blocked. The air pressure in the fermentation tank 1 will gradually increase. As time accumulates, the original pressure balance will be broken, resulting in a decrease in the dissolved oxygen content in the fermentation liquid and a decrease in metabolic efficiency, thereby affecting the fermentation process of the seaweed.

[0024] Reference Figure 2 and Figure 3, the cleaning component 5 includes a horizontal shaft rod 51 that coincides with the axis of the air outlet pipe 3. At both ends of the horizontal shaft rod 51, traveling wheels 52 are provided. A number of traveling wheels 52 are arranged in an array centered on the axis of the horizontal shaft rod 51. And a connecting rod 57 is provided between the traveling wheel 52 and the horizontal shaft rod 51. The traveling wheel 52 is rotatably connected to the end of the connecting rod 57 through a rotating shaft. A number of elastic ropes 54 are provided on the horizontal shaft rod 51. A moving ring 55 is provided at one end of the horizontal shaft rod 51 away from the fermentation tank 1.

[0025] Refer to Figure 5 , the outer diameter of the moving ring 55 is the same as the inner diameter of the air outlet pipe 3. A scraping strip 56 is welded on the outer wall of the moving ring 55. The cross section of the scraping strip 56 is triangular. The side of the scraping strip 56 close to the inner wall of the air outlet pipe 3 is set as an inclined surface, which is convenient for guiding the scraped seaweed fragments.

[0026] Specifically, when the air outlet valve 4 is opened, there is a pressure difference inside and outside the fermentation tank 1 of the fermentation tank 1, and the air flow surges into the air outlet pipe 3. Thus, under the guiding action of the traveling wheel 52, the air flow pushes the horizontal shaft rod 51 to move towards the air outlet valve 4 side. And the moving ring 55 moves synchronously with the horizontal shaft rod 51. The thrust of the air flow is greater than the elasticity of the elastic rope 54 to stretch it. When the constant pressure exhaust of this time ends, under the reset action of the elastic rope 54, it drives the moving ring 55 to quickly move back towards the fermentation tank 1 side, scraping off the residual seaweed fragments on the wall of the air outlet pipe 3. Under the guidance of the inclined surface of the scraping strip 56, the seaweed fragments scraped by the top of the moving ring 55 slide to the bottom of the scraping strip 56 under the action of gravity. When the moving ring 55 moves directly above the receiving bottle 61, the accumulated seaweed fragments fall into the receiving bottle 61 for self-cleaning, without the need for an extra power source, avoiding blockage of the air outlet pipe 3 and reducing the number of times of manual cleaning by disassembling the air outlet pipe 3.

[0027] Since the fermentation tank 1 exhausts air once every certain period of time when reaching the pressure limit during use, the thrust of the air flow can be used to clean the air outlet pipe 3 during each exhaust process, increasing the self-cleaning times of the wall of the air outlet pipe 3. It only needs to regularly rotate and disassemble the receiving bottle 61 for cleaning, and the operation is simple.

[0028] Specifically, when the air flow surges into the air outlet pipe 3 to push the horizontal shaft rod 51 to move, the traveling wheel 52 can roll along the inner wall of the air outlet pipe 3. This rolling method provides stable guidance for the horizontal shaft rod 51, enabling it to only move linearly along the axial direction of the air outlet pipe 3, avoiding deviation, shaking or rotation of the horizontal shaft rod 51 during the movement, and ensuring the stability and accuracy of the overall movement of the cleaning component 5.

[0029] Refer to Figure 2, a positioning block 53 is fixedly installed at one end of the horizontal shaft rod 51 close to the fermentation tank 1, elastic ropes 54 are connected to the outer wall of the positioning block 53 in an array, and the ends of the elastic ropes 54 away from the positioning block 53 are detachably connected to the inner wall of the fermentation tank 1.

[0030] Specifically, the elastic ropes 54 are high-temperature resistant rubber ropes, and the maximum stretching length of the elastic ropes 54 depends on the actual length of the exhaust pipe; as the service time increases, the elastic ropes 54 will experience elastic fatigue, and the new elastic ropes 54 can be replaced by disassembling the positioning block 53.

[0031] Refer to Figure 4 and Figure 5 , a hemispherical block 58 is fixedly sleeved on the outside of the horizontal shaft rod 51, and the hemispherical block 58 is located inside the scraping strip 56. The outer wall of the hemispherical block 58 is connected to the outer wall of the moving ring 55 through a fixing rod 59.

[0032] Specifically, the curved surface of the hemispherical block 58 can evenly disperse the air flow to the surroundings, forming a relatively stable low-pressure area behind the hemispherical block 58, thereby generating a force to push the hemispherical block 58 to move backward. When the air outlet valve 4 is opened, the hemispherical block 58 drives the horizontal shaft rod 51 to move away from the fermentation tank 1.

[0033] Embodiment 2, refer to Figures 1-7 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the receiving assembly 6 includes a receiving bottle 61 that can be threadedly installed at the bottom of the air outlet pipe 3. A rotating cylinder 62 is rotatably installed on the outside of the horizontal shaft rod 51 through a bearing, and the rotating cylinder 62 is located between the positioning block 53 and the hemispherical block 58. A connecting ring 63 is fixedly installed on the outer wall of the rotating cylinder 62, and a plurality of fan blades 64 are connected to the outer wall of the connecting ring 63 in an array with its axis as the center.

[0034] Refer to Figure 4 and Figure 6 , the side wall of the rotating cylinder 62 is rotatably connected to the outer wall of the hemispherical block 58. An arc-shaped scraping blade 65 is integrally formed on the outer wall of the rotating cylinder 62, and the inner wall of the arc-shaped scraping blade 65 is attached to the outer wall of the hemispherical block 58.

[0035] Specifically, under the action of gravity, the seaweed residues on the inclined surface of part of the scraping strip 56 (top) fall onto the surface of the hemispherical block 58. When the air flow passes through the air outlet pipe 3, it drives a plurality of driving fan blades 64 to rotate, so that the rotating cylinder 62 rotates along its own axis. The surface of the hemispherical block 58 is scraped off by the arc-shaped scraping blade 65, so that the seaweed residues originally accumulated on the surface of the hemispherical block 58 can smoothly fall into the receiving bottle 61, greatly improving the collection efficiency of the seaweed residues.

[0036] Refer to Figure 2 andFigure 7 A through hole 66 is formed on the wall of the air outlet pipe 3 for the seaweed debris to pass through. A friction sheet 67 is placed in the receiving bottle 61. The friction sheet 67 is a sponge sheet impregnated with water, and the friction sheet 67 is in contact with the inner wall of the receiving bottle 61.

[0037] Specifically, the friction plate 67 is preferably a sponge plate. The sponge itself has a porous structure. After being immersed in water, these pores are filled with water. When the seaweed fragments come into contact with the sponge plate, water molecules will form an adsorption force between the seaweed fragments and the sponge plate. This adsorption force is similar to the "bridge" formed by water molecules on the surfaces of two objects, which "pull" the seaweed fragments tightly on the sponge plate, making it difficult for the seaweed fragments to easily break away from the surface of the sponge plate under the action of airflow; and because the surface of the friction plate 67 is not absolutely smooth, the friction between the seaweed fragments and the surface of the friction plate 67 will increase significantly. During the exhaust process, most of the airflow flows along the axis of the horizontal shaft 51. The force generated by the airflow that moves partly into the receiving bottle 61 is not enough to overcome the adsorption force and friction force, so the seaweed fragments will remain on the friction plate 67 and will not be carried away by the airflow, which is convenient for collecting the seaweed fragments. The rest of the structure is the same as that of Example 1.

[0038] Example 3, reference Figures 1-11 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the auxiliary component 7 includes a filter screen 71 fixedly installed on the inner side of the exhaust port of the fermentation tank 1, and the filter screen 71 is annular as a whole. A driving cylinder 72 is rotatably installed on the inner side of the filter screen 71 through a bearing. A brush strip 73 is fixedly installed on the outer wall of the driving cylinder 72, and the brush surface of the brush strip 73 is in contact with the surface of the filter screen 71.

[0039] Specifically, when the gas in the fermentation tank 1 is discharged with seaweed fragments, the filter screen 71 can intercept larger seaweed fragments to prevent them from entering the inner cavity of the air outlet pipe 3 in large quantities, thereby reducing the risk of blockage of the air outlet pipe 3. The brush bar 73 is driven to rotate by the driving cylinder 72, so that the brush bar 73 cleans the seaweed fragments on the surface of the filter screen 71 and makes them fall back into the inner cavity of the fermentation tank 1.

[0040] Reference Figure 9 , Figure 10 and Figure 11 The inner cavity of the driving cylinder 72 is slidably connected with a moving rod 74, and the diameter of the moving rod 74 is the same as the inner diameter of the driving cylinder 72. The outer wall of the moving rod 74 is provided with an oblique groove 75, and the overall length of the oblique groove 75 is half the circumference of the circumference of the moving rod 74. The inner wall of the driving cylinder 72 is integrally formed with a protruding rod 76, and one end of the protruding rod 76 is located in the oblique groove 75; the end of the moving rod 74 away from the driving cylinder 72 is connected to a limit plate ( Figure 9(not labeled) shown in the figure, a reset member 77 is connected between the outer wall of the limit disk and the filter net 71, and the reset member 77 is sleeved on the outside of the moving rod 74.

[0041] Specifically, the reset member 77 is preferably a compression spring that can withstand axial compressive force, and the elastic force of the reset member 77 is less than the total elastic force of several elastic ropes 54; in the initial state (when the air outlet valve 4 is not opened), one end of the horizontal shaft rod 51 pushes the moving rod 74 into the driving cylinder 72, and at this time, the reset member 77 is in a compressed state and stores elastic potential energy.

[0042] Specifically, during constant-pressure exhaust, the horizontal shaft rod 51 moves away from the moving rod 74 under the movement of the hemispherical block 58. Under the elastic action of the reset member 77, the reset member 77 drives the moving rod 74 to be withdrawn from the driving cylinder 72, and the inclined groove 75 moves horizontally synchronously with the moving rod 74. In this way, under the guidance of the inclined groove 75, the convex rod 76 drives the driving cylinder 72 to rotate 180 degrees, so that the brush strip 73 cleans the surface of the filter net 71; when the constant-pressure exhaust ends, the horizontal shaft rod 51 resets under the pulling force of the elastic rope 54, and one end of the horizontal shaft rod 51 pushes the moving rod 74 into the driving cylinder 72, so that the convex rod 76 drives the driving cylinder 72 to rotate 180 degrees in the reverse direction, so that the brush strip 73 cleans the surface of the filter net 71 again, brushing off the attached seaweed fragments to prevent blockage.

[0043] The remaining structure is the same as that of Embodiment 2.

[0044] Combining Embodiments 1-3, the working principle of the present invention is as follows: During the fermentation process of seaweed fertilizer, the gas generated by the metabolism of microorganisms in the fermentation tank 1 accumulates continuously. When the pressure reaches the upper limit of the safety setting, the air outlet valve 4 is opened. The air pressure difference inside and outside the tank causes the air flow to rush towards the air outlet pipe 3. The filter net 71 intercepts larger seaweed fragments. At this time, the air flow pushes the horizontal shaft rod 51 and the moving ring 55 towards the air outlet valve 4 side, while stretching the elastic rope 54. The air flow drives the fan blade 64 to rotate the rotating cylinder 62 self-rotationally, and the arc-shaped scraping blade 65 scrapes off the seaweed fragments on the surface of the hemispherical block 58. After the exhaust ends, the elastic rope 54 resets and drives the moving ring 55 to move in the reverse direction. The scraping strip 56 scrapes off the seaweed fragments on the wall of the air outlet pipe 3 and makes them fall into the receiving bottle 61. The friction sheet 67 in the receiving bottle 61 adsorbs the seaweed fragments to improve the collection efficiency. During each reciprocating movement of the horizontal shaft rod 51, the brush strip 73 cleans the filter net 71 to ensure the stable operation of the entire fermentation tank 1 and ensure the normal discharge of gas in the fermentation tank 1 and the smooth progress of seaweed fermentation.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
