Description

Technical Field

[0001] This utility model relates to the field of pig farm manure fermentation technology, and in particular to a large-scale pig farm manure fermentation device. Background Technology

[0002] In existing large-scale pig farm manure fermentation, traditional equipment has significant limitations. Manual feeding is labor-intensive and inefficient, making it difficult to meet the needs of large-scale production. Fermentation temperature control is unstable, lacking efficient heating and insulation structures, leading to localized temperature differences and insufficient fermentation. Materials tend to stick to the tank walls, and uneven mixing affects fermentation quality. The discharge process is cumbersome, leaving a lot of residue. Furthermore, the equipment is inconvenient to maintain, further restricting fermentation efficiency and large-scale application, and bringing certain adverse effects to users. To address the shortcomings of existing technologies, we propose a large-scale pig farm manure fermentation device. Utility Model Content

[0003] The main purpose of this invention is to provide a large-scale pig farm manure drying and fermentation device, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A feeding channel is fixedly connected to the top of the fermentation tank, and a lifting channel is fixedly connected to the other end of the feeding channel. A feeding hopper is fixedly connected to the upper end of the lifting channel. A first servo motor is detachably connected to one end of the lifting channel. The output shaft of the first servo motor passes through the lifting channel and is detachably connected to a first rotating rod. A first spiral blade is fixedly connected to the outer surface of the first rotating rod.

[0006] A fixing box is fixedly connected to the outer surface of the fermentation tank, and an electric heating tube is wound between the fixing box and the fermentation tank. A support rod is fixedly connected to the bottom of the fermentation tank, and a fixing cylinder is fixedly connected to the upper end of the support rod. A second servo motor is detachably connected to the top of the fermentation tank. A second rotating rod is detachably connected to the output shaft of the second servo motor, and a fixing ring is fixedly connected to the outer surface of the second rotating rod. Fixing plates are fixedly connected to both sides of the fixing ring. A first scraper and a second scraper are fixedly connected to the lower end of the fixing plates. A second spiral blade is also fixedly connected to the outer surface of the second rotating rod. A discharge pipe is fixedly connected to the lower end of the fermentation tank, and a discharge valve is detachably connected to the middle of the discharge pipe. A support frame is installed on the outer surface of the fermentation tank.

[0007] Preferably, the lifting channel is inclined, the outer edge of the first helical blade is in contact with the inner wall of the lifting channel, and the helical direction of the first helical blade is adapted to the inclination angle of the lifting channel.

[0008] Preferably, the electric heating tube is spirally wound between the fermentation tank and the fixing box, and the fixing box is made of heat-insulating material.

[0010] Preferably, the second helical blade is located inside the fixed cylinder, and the outer edge of the second helical blade is in contact with the inner wall of the fixed cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This large-scale pig farm manure fermentation device automatically transports dried manure materials through an inclined lifting channel and a first spiral blade, solving the problems of low efficiency and high labor intensity of manual feeding. The design of the first spiral blade fitting snugly against the inner wall of the channel can prevent material residue from clogging. Combined with the precise introduction of the material into the fermentation tank through the feeding channel, it greatly improves the stability of feeding and provides a continuous feeding guarantee for large-scale fermentation.

[0013] This large-scale pig farm manure fermentation device, with its electric heating tubes and dual scraper and spiral blade structure, can maintain the optimal fermentation temperature through heating, and use the scraper to clean the tank wall and fixed cylinder surface residue, preventing local overheating or insufficient fermentation. The forward and reverse rotation of the second spiral blade realizes the dual functions of material turning and discharge, improving the uniformity of fermentation while simplifying the discharge process, ensuring efficient operation and convenient maintenance of the device.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a large-scale pig farm manure fermentation device includes a fermentation tank 1. A feeding channel 2 is welded to the top of the fermentation tank 1. The other end of the feeding channel 2 is welded to one side of a lifting channel 3. The lifting channel 3 is inclined, and a feeding hopper 4 is welded to its upper end. A first servo motor 5 is detachably connected to the high end of the lifting channel 3 via bolts. The output shaft of the first servo motor 5 passes through the lifting channel 3 and is detachably connected to a first rotating rod 6 via a coupling. A first spiral blade 7 is welded to the outer surface of the first rotating rod 6. The outer edge of the first spiral blade 7 fits against the inner wall of the lifting channel 3, and the spiral direction matches the inclination of the lifting channel 3. A fixing box 8 is fixedly connected to the outer surface of the fermentation tank 1. An electric heating tube 9 is wound around the annular cavity between the fixing box 8 and the fermentation tank 1. Four support rods 10 are welded to the bottom of the fermentation tank 1. A fixed cylinder 11 is welded and fixed at the upper end of the fermentation tank 1. A second servo motor 12 is detachably connected to the center of the top of the fermentation tank 1. The output shaft of the second servo motor 12 is connected to a second rotating rod 13 via a coupling. A fixed ring 14 is welded and fixed to the outer surface of the second rotating rod 13. Fixed plates 15 are welded to both sides of the fixed ring 14. A first scraper 16 and a second scraper 17 are fixedly connected to the lower end of the fixed plate 15 via bolts. The first scraper 16 is tightly fitted to the outer surface of the fixed cylinder 11. The second scraper 17 is tightly fitted to the inner wall of the fermentation tank 1. A second spiral blade 18 is welded and fixed to the outer surface of the second rotating rod 13. The outer edge of the second spiral blade 18 is fitted to the inner wall of the fixed cylinder 11. A discharge pipe 19 is welded and fixed to the center of the lower end of the fermentation tank 1. A discharge valve 20 is detachably connected to the middle of the discharge pipe 19 via a flange. A support frame 21 is welded and fixed to the lower side of the outer surface of the fermentation tank 1.

[0021] It should be noted that this utility model is a large-scale pig farm manure fermentation device. In use, the dried manure material is pushed into the feeding hopper 4, and then the first servo motor 5 is started. Driven by the first servo motor 5, the first spiral blade 7 begins to work, gradually pushing the material along the lifting channel 3 to the discharge channel 2. The material then naturally falls from the discharge channel 2 into the fermentation tank 1. Next, the electric heating tube 9 is started. Through the heating effect of the electric heating tube 9, the temperature inside the fermentation tank is raised and stabilized within a suitable fermentation range. Simultaneously, the second servo motor 12 is started to drive the second rotating rod 13 to rotate. As the second rotating rod 13 rotates, the material connected to its outer surface... The second spiral blade 18 will transport the dried manure material at the bottom of the fermentation tank 1 upwards and then fall freely, ensuring that the material is heated evenly and fermented fully. During this process, the first scraper 16 and the second scraper 17 also play a role simultaneously. They will clean the inner wall of the fermentation tank 1 and the outer surface of the fixed cylinder 11 to prevent material residue on the inner wall from affecting the fermentation effect. After sufficient fermentation, the electric heating tube 9 is turned off to stop heating, and the second servo motor 12 is turned off at the same time. Then the discharge valve 20 is opened, and the second servo motor 12 is restarted in reverse. Driven by the reverse rotation of the second servo motor 12, the second spiral blade 18 smoothly discharges the fermented product through the discharge pipe 19.
