Description

Technical Field

[0001] The present application relates to the technical field of aerobic fermentation equipment, and in particular to a novel four-axis stirring transmission device. Background Art

[0002] In the field of aerobic fermentation equipment technology, the organic solid waste and auxiliary materials in the aerobic fermentation chamber need to be fully stirred using a stirring system before fermentation to adjust the carbon-nitrogen ratio, porosity and moisture content of the mixed materials to create more suitable conditions for aerobic fermentation. Commonly used aerobic fermentation equipment stirring systems mostly use dual-axis drive, and the mixing volume per unit time is small. When the space size of the fermentation chamber is large, uneven mixing is prone to occur, resulting in anaerobic fermentation of the materials, resulting in incomplete fermentation of the materials, and thus affecting the fermentation quality. At the same time, it takes a long time to mix the materials evenly, resulting in increased energy consumption and increased equipment operating costs. Utility Model Content

[0025] Example

[0026] See also Figure 1 - Figure 3 The present application provides a technical solution: a novel four-axis stirring transmission device, comprising a reduction motor 1, a sprocket 3, a chain 4, a driven shaft 7, a blade 8, a driving shaft 9 and a frame 11, wherein the reduction motor 1 is fixed on the frame 11, and the driven shaft 7 and the driving shaft 9 are both rotatably arranged on the frame 11, and further comprising a bearing seat 5, the bearing seat 5 being fixed on the frame 11, and the driven shaft 7 and the driving shaft 9 rotatingly passing through different bearing seats 5, and the arrangement of the bearing seat 5 enables the driven shaft 7 and the driving shaft 9 to rotate more smoothly, and different sprockets 3 are respectively fixed on the outer walls of the driven shaft 7 and the driving shaft 9, and the upper and lower sprockets 3 are connected together through the chain 4 transmission;

[0027] The reduction motor 1 drives the rotation of the driving shaft 9 through the coupling 2, and drives the rotation of the driven shaft 7 through the sprocket 3 and the chain 4. There are two driven shafts 7 and driving shafts 9. The chain 4 is a double-row chain. Different blades 8 are installed on the driven shaft 7 and the driving shaft 9. The blade 8 is made of wear-resistant material. The blade 8 is detachably installed on the driven shaft 7 and the driving shaft 9. The angle of the blade 8 can be adjusted according to the situation of the stirred material. It also includes a sealing structure 6. Different sealing structures 6 are respectively installed on the driven shaft 7 and the driving shaft 9. The sealing structure 6 is composed of two dynamic seals and one stuffing box seal. When the shaft passes through the fermentation tank, the sealing structure 6 plays a double-sealing role, with good sealing effect, avoiding the leakage of toxic and harmful gases during the aerobic fermentation process. It also includes shaft-end scrapers 10. Different shaft-end scrapers 10 are respectively fixedly installed on the driven shaft 7 and the driving shaft 9. The shaft-end scrapers 10 rotate with the shaft, which can effectively scrape off the material adhered to the cabin walls at both ends of the shaft. The two ends of the driven shaft 7 and the driving shaft 9 are solid shafts, and the middle long shaft is a hollow shaft, reducing the self-weight.

[0028] Specifically, the working principle of this new type of four-shaft stirring transmission device: During use, according to the type of material, adjust the angle of the blade 8 on the driven shaft 7 and the driving shaft 9. After adjustment, inject the material into the aerobic fermentation tank. Then the reduction motor 1 works. The rotation of the output shaft of the reduction motor 1 drives the sprocket 3 and the driving shaft 9 to rotate. Under the action of the chain 4, the driven shaft 7 and the driving shaft 9 rotate synchronously. The driven shaft 7 and the driving shaft 9 drive the blade 8 and the shaft-end scraper 10 to rotate. The blade 8 realizes the stirring of the material, and the shaft-end scraper 10 scrapes off the material adhered to the cabin walls at both ends of the shaft. This new type of four-shaft stirring transmission device uses two vertical reduction motors 1 to drive the rotation of two shafts respectively through the chain 4. The blades 8 on the shafts can rotate synchronously or reversely, which can make the material stirring more uniform. The chain 4 is a double-row chain, with large transmission power, strong load-bearing capacity, reliable work, high efficiency, higher safety, long service life, stable structure. When the shaft passes through the fermentation tank, a combination of two dynamic seals and one stuffing box seal is adopted, which plays a double-sealing role, with good sealing effect, avoiding the leakage of toxic and harmful gases during the aerobic fermentation process. The stirring blade 8 is made of wear-resistant material, with good wear resistance and corrosion resistance, and long service life. The stirring blade 8 is detachable. It can not only adjust the angle to change the stirring effect, but also facilitate the replacement and maintenance of the blade 8. The stirring blades 8 are arranged relatively with a fixed included angle. During the stirring process, while the material makes a circular motion along the stirring shaft, the material can make a relative axial motion, making the material stirring more sufficient, with high mixing efficiency, energy saving and consumption reduction. Shaft-end scrapers 10 are installed at both ends of the rotating shaft. The shaft-end scrapers 10 rotate with the shaft, which can scrape off the adhered material on the cabin walls at both ends of the fermentation tank shaft, avoiding anaerobic fermentation, ensuring the fermentation quality, and at the same time reducing the equipment operation cost.
