Description

Technical Field

[0001] This utility model relates to the field of biological enzyme production technology, specifically a pulping device for preparing enzyme fertilizer from agricultural perishable waste. Background Technology

[0002] Bioenzymes are a class of biological macromolecules, typically a type of protein. The production of bioenzymes usually involves a microbial fermentation process, a method of large-scale enzyme production utilizing the ability of microorganisms to synthesize and secrete enzymes. Bioenzymes can be produced from agricultural waste (such as kitchen waste, discarded fruit and vegetable peels, and rotten fruits and vegetables). The production process mainly involves pulping the agricultural waste into a slurry, then adding the slurry, microbial strains, and a nutrient-rich culture medium into a fermenter for fermentation. Commonly used microbial strains include bacteria (such as Pasteurella), fungi (such as Aspergillus and Mucor), and yeast. Commonly used culture media include carbon sources (such as glucose), nitrogen sources (such as amino acids and urea), minerals, vitamins, and growth factors. Batch or continuous fermentation is then carried out by controlling the conditions of the fermenter (such as temperature, pH, oxygen supply, and stirring speed).

[0003] Before existing bio-enzyme fermentation, agricultural waste (raw material) needs to be pulped into a slurry using a bio-enzyme pulping device. This significantly increases the surface area of ​​the waste, making it easier for microorganisms to utilize. The finer particles mean that microorganisms can contact and decompose the substrate more quickly, thus improving enzyme production efficiency. The pulped waste can be mixed more evenly with the fermentation medium. This uniform mixing helps ensure that microorganisms have equal access to all nutrients during cultivation, avoiding inconsistent growth caused by uneven nutrient distribution. During microbial fermentation, the material, after being crushed and pulped, undergoes more rapid metabolic processes due to the disruption of its material structure and the increased surface area. This not only shortens fermentation time but also improves the efficiency of the entire production process.

[0004] When whole or large pieces of fruit are directly placed into the pulping machine, their size and hardness can cause blockages and damage to internal mechanical components such as blades and motors. Rounder fruits may also be bounced off the blades, preventing pulping. Therefore, existing bio-enzyme pulping devices require large fruits to be cut into pieces before being added to the pulping tank. However, this requires additional manpower and time for cutting the fruits, increasing production time, operational complexity, and labor costs. To address these issues, a pulping device for preparing enzyme fertilizer from agricultural waste is provided. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a pulping device for preparing enzyme fertilizer from agricultural perishable waste, including a pump 1, such as... Figure 1 As shown, pump 1 is installed inside the pulping tank. Pump 1 is preferably a 0.5kW to 100kW water pump, specifically a cutting pump of model WQK65-25. Pump 1 includes a turbine housing, an impeller, and a motor. The turbine housing is fixedly connected to one end of the motor, and the impeller is rotatably installed inside the turbine housing. The output shaft of the motor passes through the turbine housing and is fixedly connected to the impeller. Starting the motor drives the impeller to rotate inside the turbine housing. When pump 1 is installed inside the pulping tank, pump 1 is placed vertically with the turbine housing at the top, and the feed inlet of the turbine housing facing upwards, while the discharge outlet is located on the side of the turbine housing.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a combined cutter head 3 is installed above the turbine housing of pump 1. The combined cutter head 3 includes a crushing cutter 31 and a cutting cutter 32. Both the crushing cutter 31 and the cutting cutter 32 are rotatably mounted on the upper end of the turbine housing of pump 1, with the crushing cutter 31 located above the cutting cutter 32. Both the crushing cutter 31 and the cutting cutter 32 are coaxially connected to the impeller of pump 1. After the motor of pump 1 is started, it can drive the impeller, the crushing cutter 31 and the cutting cutter 32 to rotate synchronously.

[0024] like Figure 3 As shown, the crushing blade 31 consists of four blades with sharp, upturned tips. The angle between the blades and the cutting blade 32 is between 30° and 45°. The cutting blade 32 has an S-shaped structure and can cut the material it contacts.

[0025] When performing pulping operations, the pulping tank must first be filled with water, with the water level 300mm to 1000mm above the tip of the crusher blade 31. During use, start pump 1, then add agricultural waste into the pulping tank. Because the impeller of pump 1 generates vortices upon rotation, the agricultural waste moves in the following direction: Figure 5 As indicated by the inner arrow F1, the material moves towards the feed inlet of the turbine housing. After moving downwards, the agricultural waste first contacts the rotating crushing blade 31. The blade tip of crushing blade 31 breaks up whole or large pieces of material, forming small lumps or powder. Then, it contacts the cutting blade 32 to further pulverize the material. The pulverized material mixes with water in the pulping tank to form a slurry. After pump 1 starts, the water flow inside pump 1... Figure 5 The circulation proceeds as indicated by the inner arrow F2, meaning the slurry formed by mixing the crushed agricultural waste with water is also circulated... Figure 5 The inner arrow F2 direction is the same for the circulation. The agricultural waste circulation process is as follows: it is cut by the combined cutter head 3, mixed with water to form a slurry, passes through the turbine housing of the pump 1, and is moved upward by the circulating water flow. After repeated circulation, the slurry becomes finer after being cut and stirred multiple times by the combined cutter head 3. By starting the pump, the liquid flow in the pulping tank is stirred and the combined cutter head is rotated. The agricultural waste that needs to be pulped is limited by the tank body. The crushing blade breaks the whole or large pieces of agricultural waste into blocks or granules. Then, the cutting blade breaks the agricultural waste into a slurry.

[0026] However, in actual operation, it was found that when agricultural waste comes into contact with the crushing blades 31, large, round or hard pieces of fruit and vegetables are thrown off by the rotating blades 31 and then fall to the bottom of the pulping tank after contacting the inner edge of the pulping tank. However, the circulating water flow does not easily move the large pieces of fruit and vegetables, causing them to accumulate in the pulping tank and not be pulped. Therefore, to prevent large, round or hard pieces of fruit and vegetables from being thrown off by the rotating crushing blades 31, a tank 2 is fixedly connected to the upper end of the pump 1. Figure 1 and Figure 5 As shown, the combined cutter head 3 is located inside the tank body 2. After the agricultural waste is put into the pulping tank, the vortex will carry the agricultural waste into the tank body 2. The tank body 2 limits the agricultural waste to prevent large pieces of melons and fruits from being blown away by the rotating crushing blade 31.

[0027] The pulping tanks are available in capacities ranging from 0.05t to 5t, with a significant size difference, allowing for the selection of different tank sizes based on the amount of agricultural waste to be processed. Meanwhile, the height of tank 2 is set between 50mm and 500mm, allowing for the selection of the appropriate tank size based on the chosen pulping tank.

[0028] like Figure 1 and Figure 2 As shown, in order to stabilize the installation of pump 1, a fixing frame 4 is fixedly installed on the outer wall of the motor of pump 1. The fixing frame 4 connects pump 1 and slurry tank, thereby stabilizing pump 1 and preventing the pump 1 from tilting due to vibration generated after pump 1 starts.

[0029] When pump 1 drives the slurry to circulate, the slurry at the bottom of the mixing tank is difficult to move. In order to further agitate the slurry at the bottom of the mixing tank and enable better circulation, multiple blades 51 are rotatably installed inside the mixing tank. Figure 4 As shown, the fixing frame 4 includes a ring track and multiple supports. The supports are evenly distributed in a ring around the pump 1 as its axis. One end of each support is fixedly connected to the outer wall of the pump 1, and the other end is fixedly connected to the inner wall of the pulping tank. The ring track is fixedly connected to the supports. A rotating ring 5 is rotatably mounted on the ring track of the fixing frame 4, and multiple blades 51 are evenly distributed in a ring array on the rotating ring 5. A discharge pipe 11 is fixedly connected to the discharge port of the turbine housing of the pump 1. The blades 51 are inclined, as shown... Figure 5 As shown, the angle between the blade 51 and the rotating ring 5 is between 45° and 60°. After the slurry is discharged through the discharge port, it is discharged through the lower end of the discharge pipe 11. The discharged slurry will impact the end face of the blade 51, thereby driving the rotating ring 5 to rotate on the annular track of the fixed frame 4. At the same time, the rotation of multiple blades 51 will agitate the slurry in the pulping tank, and further agitate the slurry at the bottom of the pulping tank, so that the slurry can be better circulated through the pump 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
