Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to a microbial fertilizer fermentation device. Background Technology

[0002] In the industrial production of microbial fertilizers, fermentation equipment is the core equipment for ensuring the metabolism of microbial communities and improving product quality. Its uniformity of mixing and ease of cleaning directly affect fermentation efficiency and product qualification rate.

[0003] In the existing technology, the disassembly and cleaning process of the device is cumbersome and inefficient. The top cover and tank of the existing fermentation device are often fastened with multiple sets of bolts. The stirring shaft and drive motor often adopt an integrated rigid connection or a complex coupling structure. During disassembly, multiple components such as bearings and seals need to be disassembled in sequence. This design makes it impossible to remove the stirring device as a whole. The dead corners of the inner wall of the tank and the residual materials at the root of the stirring blades are difficult to clean thoroughly, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a microbial fertilizer fermentation device, comprising: a tank body, a top cover threadedly connected to the top of the tank body, a pressure relief device fixedly connected to the inner wall of the top cover, a servo motor fixedly connected to the outer wall of the top cover, a stirring device disposed inside the tank body, and a positioning groove formed on the inner wall of the tank body; the stirring device includes a stirring shaft, a spiral stirring blade fixedly connected to the outer wall of the stirring shaft, a scraper fixedly connected to the outer wall of the stirring shaft, a limit ring rotatably connected to the top outer wall of the stirring shaft, and a positioning block fixedly connected to the outer wall of the limit ring. The spiral stirring blade on the outer wall of the stirring shaft rotates with the shaft, spirally agitating the microbial fertilizer inside the tank to achieve thorough mixing of the material from top to bottom and inside to outside; the scraper on the outer wall of the stirring shaft is slidably connected to the inner wall of the tank, and can scrape off the fertilizer adhering to the inner wall of the tank during rotation, avoiding material residue that affects the fermentation effect and subsequent cleaning.

[0005] Preferably, the outer wall of the limiting ring is slidably connected to the inner wall of the tank, the outer wall of the positioning block is slidably connected to the inner wall of the positioning groove, and the outer wall of the scraper is slidably connected to the inner wall of the tank. The limiting ring on the outer wall of the top of the stirring shaft is slidably connected to the inner wall of the tank, and the positioning block on the outer wall of the limiting ring is embedded in the positioning groove on the inner wall of the tank, which can limit the radial displacement of the stirring shaft when it rotates and ensure stable stirring.

[0006] Preferably, an installation cylinder is fixedly connected to the top end of the stirring shaft, an installation groove is provided in the wall of the installation cylinder, an installation rod is slidably connected to the inner wall of the installation cylinder, and a connecting rod is fixedly connected to the outer wall of the installation rod.

[0007] Preferably, the outer wall of the mounting rod is rotatably connected to the inner wall of the top cover, the outer wall of the mounting rod is fixedly connected to the output end of the servo motor, and the outer wall of the connecting rod is slidably connected to the inner wall of the mounting groove. When the servo motor is started, it drives the mounting rod to rotate. The mounting rod, through the connecting rod on its outer wall, engages with the mounting groove of the mounting cylinder, transmitting torque to the mounting cylinder. Through the fixing of the mounting cylinder to the stirring shaft, the stirring shaft is ultimately driven to rotate synchronously, providing power for stirring the fermentation material.

[0008] Preferably, the pressure relief device includes a pressure relief cylinder, a plug rod slidably connected to the inner wall of the pressure relief cylinder, a plug plate fixedly connected to the outer wall of the plug rod, a vent hole in the wall of the plug plate, and an exhaust hole in the wall of the pressure relief cylinder. When the gas pressure inside the tank increases, the gas pushes the plug rod upward, compressing the push spring. When the plug rod slides from the bottom to the top of the pressure relief cylinder, the vent hole on the plug plate connects with the exhaust hole, and the gas inside the tank is discharged through the vent hole to the exhaust hole, thus achieving pressure relief.

[0009] Preferably, the outer wall of the pressure relief cylinder is fixedly connected to the inner wall of the top cover, and an adjusting block is threadedly connected to the inner wall of the top of the pressure relief cylinder. A push spring is fixedly connected to the bottom end of the adjusting block, and the end of the push spring away from the adjusting block is fixedly connected to the top of the plug rod. Rotating the adjusting block at the top of the pressure relief cylinder can change the initial compression of the push spring, thereby adjusting the pressure relief threshold to adapt to the pressure requirements of different fermentation stages.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model features a stirring device with spiral stirring blades rotating with the shaft to spirally agitate the microbial fertilizer inside the tank, achieving thorough mixing of the material from top to bottom and inside to outside. The scraper on the outer wall of the stirring shaft is slidably connected to the inner wall of the tank, and can scrape off the fertilizer adhering to the inner wall of the tank during rotation, avoiding material residue that may affect the fermentation effect and subsequent cleaning. Through the quick-connect structure of the mounting rod, connecting rod, mounting cylinder, and mounting groove, combined with the stirring device that can be removed as a whole, the top cover and the tank can be quickly separated without disassembling complex parts, thus allowing for cleaning of the entire device.

[0012] 2. This utility model achieves material mixing by setting a servo motor to drive the spiral stirring blades, thereby improving the contact efficiency between microorganisms and substrates and shortening the fermentation cycle; the scraper removes residue from the tank wall, reducing waste and pollution; the pressure relief device automatically adjusts the pressure inside the tank, automatically venting when the pressure is too high and automatically sealing when the pressure drops, without the need for manual intervention, ensuring fermentation safety.

[0019] Example:

[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a microbial fertilizer fermentation device, comprising: a tank 1, a top cover 2 threadedly connected to the top of the tank 1, a pressure relief device 3 fixedly connected to the inner wall of the top cover 2, a servo motor 4 fixedly connected to the outer wall of the top cover 2, a stirring device 5 disposed inside the tank 1, and a positioning groove 6 formed on the inner wall of the tank 1; the stirring device 5 includes a stirring shaft 53, a spiral stirring blade 56 fixedly connected to the outer wall of the stirring shaft 53, a scraper 57 fixedly connected to the outer wall of the stirring shaft 53, a limit ring 51 rotatably connected to the top outer wall of the stirring shaft 53, and a positioning block 52 fixedly connected to the outer wall of the limit ring 51.

[0021] The outer wall of the limiting ring 51 is slidably connected to the inner wall of the tank 1, the outer wall of the positioning block 52 is slidably connected to the inner wall of the positioning groove 6, and the outer wall of the scraper 57 is slidably connected to the inner wall of the tank 1.

[0022] An installation cylinder 54 is fixedly connected to the top end of the stirring shaft 53. An installation groove 55 is provided in the wall of the installation cylinder 54. An installation rod 58 is slidably connected to the inner wall of the installation cylinder 54. A connecting rod 59 is fixedly connected to the outer wall of the installation rod 58.

[0023] The outer wall of the mounting rod 58 is rotatably connected to the inner wall of the top cover 2, the outer wall of the mounting rod 58 is fixedly connected to the output end of the servo motor 4, and the outer wall of the connecting rod 59 is slidably connected to the inner wall of the mounting groove 55.

[0024] The pressure relief device 3 includes a pressure relief cylinder 31, a plug rod 35 is slidably connected to the inner wall of the pressure relief cylinder 31, a plug plate 36 is fixedly connected to the outer wall of the plug rod 35, a vent hole 37 is provided in the wall of the plug plate 36, and an exhaust hole 33 is provided in the wall of the pressure relief cylinder 31.

[0025] The outer wall of the pressure relief cylinder 31 is fixedly connected to the inner wall of the top cover 2. An adjusting block 32 is threadedly connected to the inner wall of the top of the pressure relief cylinder 31. A pushing spring 34 is fixedly connected to the bottom of the adjusting block 32. The end of the pushing spring 34 away from the adjusting block 32 is fixedly connected to the top of the plug rod 35.

[0026] Working principle:

[0027] When in use, the servo motor 4 is started, which drives the mounting rod 58 to rotate. The mounting rod 58 engages with the mounting groove 55 of the mounting cylinder 54 through the connecting rod 59 on the outer wall, transmitting torque to the mounting cylinder 54. Through the fixing of the mounting cylinder 54 and the stirring shaft 53, the stirring shaft 53 is finally driven to rotate synchronously, providing power for stirring the fermentation material. The spiral stirring blades 56 on the outer wall of the stirring shaft 53 rotate with the shaft, spirally turning the microbial fertilizer in the tank, realizing full mixing of the material from top to bottom and inside to outside. The scraper 57 on the outer wall of the stirring shaft 53 is slidably connected to the inner wall of the tank 1. When rotating, it can scrape off the fertilizer adhering to the inner wall of the tank 1, avoiding material residue from affecting the fermentation effect and subsequent cleaning.

[0028] When the gas pressure inside the tank increases, the gas pushes the plug rod 35 upward, compressing the push spring 34. When the plug rod 35 slides from the bottom to the top of the pressure relief cylinder 31, the vent hole 37 on the plug plate 36 connects with the exhaust hole 33, allowing the gas inside the tank to escape through the vent hole 37 to the exhaust hole 33, thus releasing pressure. After pressure relief, the pressure inside the tank decreases, pushing the spring 34 back to its original position, causing the plug rod 35 to fall back and re-seal the bottom of the pressure relief cylinder 31. Rotating the adjusting block 32 at the top of the pressure relief cylinder 31 changes the initial compression of the push spring 34, thereby adjusting the pressure relief threshold to adapt to the pressure requirements of different fermentation stages.

[0029] During assembly, cover the tank body 1 with the top cover 2, insert the mounting rod 58 into the mounting cylinder 54, and simultaneously slide the connecting rod 59 into the mounting groove 55 to complete the connection of the power transmission structure. Then tighten the threads of the top cover 2. During disassembly and cleaning, unscrew the top cover 2 in the opposite direction. The mounting rod 58 and the mounting cylinder 54 can quickly separate as the top cover separates from the tank body 1. Then, by pulling the limiting ring 51 upward, it drives the stirring shaft 53 to move upward until the positioning block 52 disengages from the positioning groove 6, thereby cleaning the entire device without disassembling complex parts, achieving convenient cleaning of the tank body, top cover, and stirring device.

[0030] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
