The upper bearing 9 is formed by the upper bearing positioning flange 5 and the large gear ring 8. Positioning together, the lower bearing 12 is jointly positioned by the lower bearing locating flange 10 and the lower bearing locating sleeve 11. The spiral belt 16 is located on the inner wall of the drum 14 and rotates synchronously with the drum 14.

The screw 13 is located between the upper bearing locating flange 5 and the lower bearing locating flange 10, the number is ≥2, and its function is mainly to ensure the rigidity and operational stability of the rotating drum screw feeder 03.

[0030] The material is conveyed by the rotating drum screw feeder 03, enters the longitudinal screw feeder 04, and is fed into the anaerobic reactor 06 by the screw 010. The feed port 05 at the lower end of the longitudinal screw feeder 04 is set below the fermentation liquid surface of the anaerobic reactor 06. During the process of conveying the material downward to the feed port 05 by the screw 010, the raw materials are forced into the fermentation by mechanical force The liquid is soaked in the liquid, and then discharged into the anaerobic reactor 06 through the feed port 05 to mix with the fermentation liquid; at the same time, the feed port 05 is set under the surface of the fermentation liquid, which effectively utilizes the liquid sealing effect to connect the inside of the reactor with the feed The feeding device is isolated, while ensuring the anaerobic environment inside the reactor, the contact time between the raw material and the fermentation broth is increased, and the sealing cost between the feeding device and the outside is reduced.

[0031] See Figure 4 As shown, the operation mode of the fully mechanically driven sampling device in this embodiment is "mechanically driven to sample as a whole by part", and its shape is a slender cylindrical cylinder, which mainly includes: a piston cylinder 17, a sampling port 18. Sample port 19, transmission gear 20, rocker 21, transmission rack 22, first piston 23, second piston 24, piston positioning sleeve 25, sampling chamber 26, plastic plate 27, rubber seal 28, piston rod 29, sampling The device fixes the flange 30, the sampling positioner 31, the sampling positioner 32 and the air hole 33. The operation mode of this sampling device is "mechanical drive to sample as a whole by part", which completely avoids the use of hydraulic pressure and gravity to sample high solid concentration anaerobic fermentation materials, such as more liquid and less solid, difficult to control sampling volume, and blockage. There are many problems such as unsuitable opening and closing of pipelines and valves after corrosion.

[0032] A sampling device fixing flange 30 is set on the outer wall of the reactor 06 where sampling is required, and the piston cylinder 17 is installed on the sampling device fixing flange 30 according to the normal direction of the curved surface. About 1/2 is located inside the reactor 06, and the rest It is located outside the reactor 06 and serves as the sampling transport channel of the fully mechanically driven sampling device. The sampling port 18 is an opening located on the side wall of the piston cylinder 17 to connect the inside of the piston cylinder 17 with the inside of the reactor 06, and is used to extract samples of the materials inside the reactor 06; The opening inside the cylinder 17 communicating with the outside of the reactor 06 is used to discharge the sample taken. The first piston 23 and the second piston 24 are fixed on the piston rod 29, and are mainly composed of a plastic plate 27 and a rubber gasket 28 arranged at intervals. The rubber gasket 28 is in interference fit with the inner wall of the piston cylinder 17, thereby acting as a seal. The spaced plastic plates 27 function to increase the rigidity of the piston and reduce the overall thickness of the rubber gasket 28 to reduce friction and energy consumption. The first piston 23 and the second piston 24 are positioned by the piston positioning sleeve 25, and the space between the first piston 23 and the second piston 24 and the inner wall of the piston cylinder 17 forms a sampling chamber 26. The "driving system" of this fully mechanically driven sampling device mainly includes transmission gears 20, rocker arms 21, transmission racks 22, etc., and can also be driven by electric motors, hydraulics, etc. This embodiment only introduces the simplest and easy manual drive A form of

[0033] Drive the transmission gear 20 to rotate by rotating the rocker arm 21, the transmission rack 22 meshes with the transmission gear 20, and the transmission gear 20 is arranged on the end of the transmission rack 22 outside the piston cylinder 17, changing the circular motion of the gear into a linear motion; The transmission rack 22 passes through the piston cylinder 17 and is connected to the piston rod 29, and moves linearly with the transmission rack 22, and at the same time drives the first piston 23 and the second piston 24 to move in the piston cylinder 17, thereby causing the sampling chamber 26 to move back and forth , Realize the sampling and sampling process.

[0034] When sampling is required, the driving system drives the sampling chamber 26 to move to the inside of the reactor 06, so that the sampling chamber 26 communicates with the inside of the reactor 06 through the sampling port 18, and the inner wall surface of the end of the piston cylinder 17 in the anaerobic reactor 06 There is a sampling positioner 31 for resisting the second piston 24. The sampling positioner 31 performs sampling and positioning of the sampling cavity 26. When the second piston 24 is blocked by the sampling positioner 31, it means that the sampling cavity 26 has reached the sampling point. In the best position, the material in the sampling layer is pressurized and poured into the sampling cavity 26 from the sampling port 18. During the sampling process, the connected sampling cavity 26 has become a part of the internal space of the reactor 06, thereby ensuring that the sampling cavity 26 The consistency of the material liquid sample and the sampling layer as a whole;

[0035] After sampling, it enters the sampling process. The driving system drives the sampling chamber 26 to move to the outside of the reactor 06. The liquid sample in the sampling chamber 26 is pushed forward by the second piston 24, and the whole moves to the sample outlet 19 along with the sampling chamber 26. A sampling positioner 32 is provided on the inner wall surface of the end of the piston cylinder 17 outside the anaerobic reactor 06, and the sampling cavity 26 is positioned by the sampling positioner 32. When the first piston 23 is blocked by the sampling When the positioner 32 is positioned, it indicates that the sampling cavity 26 has reached the best position for sampling. At this time, the sealing plate of the sampling port 19 is opened to take out the sample. An air hole 33 is provided on the side wall of the piston cylinder 17 between the first piston 23 and the closed end of the piston cylinder 17 outside the anaerobic reactor 06. Its main function is to avoid the formation between the first piston 23 and the closed end of the piston cylinder 17 The confined space (the confined space will form high pressure and negative pressure resistance) to ensure the continuous and smooth operation of the fully mechanically driven sampling device.

[0036] The fully mechanically driven sampling device and the reactor 06 are sealed by double pistons. The sampling stage is sealed by the first piston 23 and the sampling stage is sealed by the second piston 24. The structure is simple and the reliability is strong, ensuring the reactor 06 The internal environment is not affected by the outside world.
