Description

Technical Field

[0001] The present invention relates to the technical field of biological fertilizer preparation, and specifically provides a biological fertilizer preparation device and a usage method based on the resource utilization of cyanobacteria sludge. Background Art

[0002] Cyanobacteria are large single-celled prokaryotes that can perform oxygenic photosynthesis. They are rich in nutrients such as nitrogen, phosphorus, and potassium required by plants and are a good green fertilizer. Therefore, a biological fertilizer based on cyanobacteria sludge is commonly available on the market. When producing and preparing the biological fertilizer from cyanobacteria sludge, it generally needs to go through processes such as raw material pretreatment (ensuring impurity screening and dehydration, etc.) - fermentation - pulverization.

[0003] The existing Chinese patent application with the publication number CN113816781A discloses a device and method for preparing a selenium-rich liquid fertilizer for blueberries using cyanobacteria hydrothermal solution, including a fermentation tank having an exhaust port, a drain port, and an air inlet; an aeration pump whose pumping end is connected to the air inlet of the fermentation tank; a collection cylinder connected to the drain port of the fermentation tank through a collection pipe; and a fragmentation and feeding mechanism that can perform fragmentation and pulverization on the material for supplementation into the fermentation tank. In the preparation of this invention, the fragmentation and feeding mechanism can prepare cyanobacteria powder, straw powder, and reed powder. First, the cyanobacteria powder is prepared into cyanobacteria hydrothermal solution and then fermented together with the straw powder and reed powder, and finally, a composite selenium fertilizer solution is supplemented, with high preparation efficiency and quality.

[0004] However, the biological fertilizer preparation device has the following defects in specific use:

[0005] 1. When the existing biological fertilizer preparation device uses cyanobacteria sludge as the raw material to produce and prepare biological fertilizer, it needs to go through multiple steps such as raw material pretreatment - fermentation - pulverization to complete. However, when the traditional device pre-treats the cyanobacteria sludge raw material, it generally needs to use special devices for raw material screening and water content control (dehydration) operations respectively. The equipment cost is high and it is difficult to directly transport the treated cyanobacteria sludge to the next step, resulting in low efficiency in processing cyanobacteria sludge into biological fertilizer.

[0006] 2. When the existing biological fertilizer preparation device is in production and processing, it is necessary to ferment the cyanobacteria sludge raw material to make biological fertilizer. However, when the yeast for fermentation is transported into the fermentation tank for the fermentation operation of the raw material, the mixing efficiency of the yeast and the cyanobacteria sludge raw material is low, and it takes a long time for the stirring and mixing of the two, resulting in low efficiency in processing cyanobacteria sludge into biological fertilizer.

[0049] The present invention also provides a usage method of a biological fertilizer preparation device based on the resource utilization of cyanobacteria sludge, which includes a biological fertilizer preparation device based on the resource utilization of cyanobacteria sludge. It is characterized by including the following steps:

[0050] S1. When preparing biological fertilizer with cyanobacteria sludge as the raw material, first pour the collected and stored cyanobacteria sludge into the interior of the pretreatment tank, and perform pretreatment on the cyanobacteria sludge through the sludge pretreatment component. At this time, the sludge pretreatment component screens the excess impurities of the cyanobacteria sludge and adjusts the C / N ratio and moisture content inside the cyanobacteria sludge after screening;

[0051] S2. After the pretreatment of the cyanobacteria sludge is completed, the treated cyanobacteria sludge is transported to the interior of the fermentation chamber through the feeding component, and yeast is synchronously transported while the feeding component transports the cyanobacteria sludge, improving the efficiency of preparing the pretreated cyanobacteria sludge in the subsequent process;

[0052] S3. Among them, the yeast and the pretreated cyanobacteria sludge are fermented inside the fermentation chamber, and the fermented cyanobacteria sludge bio-sludge is transported to the interior of the crushing chamber through the feeding pipe. Then, the crushing chamber crushes the cyanobacteria sludge bio-sludge, and the crushed cyanobacteria sludge bio-sludge is stored in the interior of the recycling box;

[0053] S4. When fermenting and crushing the cyanobacteria sludge, the components inside the sludge fermentation and crushing component operate simultaneously. While the next group of cyanobacteria sludge is fermented, the crushing operation of the previous group of cyanobacteria sludge bio-sludge is carried out, improving the efficiency of preparing the cyanobacteria sludge.

[0054] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0055] 1. In the bio-fertilizer preparation equipment and its usage method based on the resource utilization of cyanobacteria sludge, when pre-treating the cyanobacteria sludge, the central control port drives the first motor to operate, enabling the first rotating shaft, third gear, fourth gear, cutting fan blades, and slicing blades connected to the output end of the first motor to operate, performing rotary cutting on the imported cyanobacteria sludge, and improving the effect of impurity screening of the cyanobacteria sludge through the screening mesh subsequently. At the same time, when the first rotating shaft rotates, it will synchronously drive the first gear, second gear, and stirring roller installed on its outer side to rotate, accelerating the stirring and mixing effect of the screened cyanobacteria sludge and the dehydrating agent. Moreover, while the first rotating shaft rotates, it will drive the spiral raceway installed on its outer side to rotate spirally, causing the cyanobacteria sludge and the dehydrating agent at the bottom to move to the top, forming an internal circulation inside the pre-treatment tank, making the stirring and mixing of the cyanobacteria sludge and the dehydrating agent more thorough, ensuring the efficiency of pre-treating the cyanobacteria sludge, and with low cost;

[0056] 2. In the bio-fertilizer preparation equipment and its usage method based on the resource utilization of cyanobacteria sludge, when fermenting and pulverizing the pre-treated cyanobacteria sludge, the second motor can drive the output end to engage with the gear set, transmission belt, movable shaft, sixth gear, fifth gear, second rotating shaft, and stirring fan blades to operate, accelerating the fermentation efficiency of the yeast and the cyanobacteria sludge inside the fermentation chamber. At the same time, while fermenting the cyanobacteria sludge inside the fermentation chamber, the operation of the engaging gear set can synchronously drive the pulverizing wheels connected to the internal gears thereof to rotate (the two pulverizing wheels rotate in opposite directions), pulverizing the algal sludge bio-fertilizer after the previous fermentation, and improving the efficiency of fermenting and pulverizing the cyanobacteria sludge. Moreover, the pulverized bio-fertilizer can be stored inside the recycling bin, facilitating the subsequent utilization of the pulverized bio-fertilizer;

[0057] 3. In the bio-fertilizer preparation equipment and its usage method based on the resource utilization of cyanobacteria sludge, when transporting the pre-treated cyanobacteria sludge to the inside of the fermentation chamber for fermentation, the cyanobacteria sludge located inside the feeding pipe and the shunt pipe can be simultaneously transported to the inside of the fermentation chamber for fermentation in cooperation with the yeast transported through the yeast conveying pipe by the yeast storage tank. At this time, during the transportation process, the yeast has already been mixed with the transported cyanobacteria sludge, and in cooperation with the subsequent stirring operation during the fermentation of the cyanobacteria sludge, it can improve the fermentation efficiency of the cyanobacteria sludge. At the same time, the yeast and the cyanobacteria sludge input into the fermentation chamber will flow through the circulation port and the frustum protrusion provided at the bottom, and will not conflict with or interfere with the cross positioning frame part supporting the second rotating shaft;

[0058] 4. In the biological fertilizer preparation equipment and its usage method based on the resource utilization of cyanobacteria sludge, the pretreatment, fermentation of cyanobacteria sludge, and the pulverization operation of the finished biological fertilizer can be carried out independently and cooperate with each other. That is, when a group of cyanobacteria sludge is being pretreated, the pretreated cyanobacteria sludge can be fermented; when the cyanobacteria sludge is being fermented, the pulverization of the biological fertilizer after fermentation can be carried out, maximizing the efficiency of preparing biological fertilizer from cyanobacteria sludge.

[0083] Please refer to Figures 1-13 , a biological fertilizer preparation device based on the resource utilization of cyanobacteria sludge, including a device bottom plate 10, a pretreatment tank 20, a preparation box body 30, and a biological fertilizer integrated preparation mechanism 40. On one side of the top of the device bottom plate 10, a pretreatment tank 20 is installed. A preparation box body 30 is arranged on the side of the pretreatment tank 20.

The preparation box body 30 is composed of a fermentation chamber 301 at the top and a crushing chamber 302 at the bottom. The fermentation chamber 301 and the crushing chamber 302 are connected by two sets of feeding pipes 303. Among them, the biological fertilizer integrated preparation mechanism 40 includes a sludge pretreatment component 50, which is arranged inside the pretreatment tank 20 and performs pretreatment operations on the cyanobacteria sludge poured into the pretreatment tank 20.

[0084] In the present invention, a reagent pipeline 201 is connected to the pretreatment tank 20 and conveys a dehydrating agent into the pretreatment tank 20.

[0085] The above working principle: When preparing biological fertilizer from cyanobacteria sludge as raw material, the collected cyanobacteria sludge is poured into the interior of the pretreatment tank 20 through the feed inlet at the top of the pretreatment tank 20, and through the operation of the sludge pretreatment component 50, the cyanobacteria sludge is automatically screened, enabling the impurities inside the cyanobacteria sludge to be separated from the sludge. Subsequently, the sludge pretreatment component 50 can simultaneously mix the screened sludge with the added dehydrating agent to control and remove the excess moisture inside it. At the same time, the dehydrated cyanobacteria sludge can be transported to the interior of the fermentation chamber 301 through the feeding component 60, and the operation of the sludge fermentation and crushing component 70 can accelerate the fermentation efficiency of the cyanobacteria sludge. Moreover, the method of mixing the cyanobacteria sludge with yeast is carried out simultaneously when the cyanobacteria sludge is input, which can effectively improve the fermentation effect of the cyanobacteria sludge. And when fermenting the next batch of cyanobacteria sludge, the sludge fermentation and crushing component 70 can simultaneously perform the crushing operation on the sludge bio-sludge after the previous batch of fermentation, so that the crushed bio-sludge can fall into the interior of the recycling bin 700 for storage.
