Description

Technical Field

[0001] The invention relates to the technical field of earthworm organic water-soluble fertilizer preparation, in particular to an enzymatic hydrolysis device for preparing earthworm organic water-soluble fertilizer. Background Art

[0002] Live earthworms are cleaned and beaten, then mixed with water to form a uniform slurry, which is then fermented and enzymatically hydrolyzed to prepare earthworm organic water-soluble fertilizer; fermentation and enzymatic hydrolysis are aimed at maximizing the retention of active substances (such as enzymes, microbial flora) and nutrients in the earthworms.

[0003] During the enzymatic hydrolysis process of earthworm organic water-soluble fertilizer, Bacillus natto needs to be added. This bacterium is a facultative anaerobic bacterium. A low oxygen environment (DO 0.2–0.5 mg / L) can promote its proliferation and enzyme secretion. Excessive oxygen will cause the active peptides in earthworm protein to oxidize, reducing the biological activity of the fertilizer. Therefore, during the enzymatic hydrolysis process of earthworm organic water-soluble fertilizer, the DO value in the enzymatic hydrolysis tank needs to be strictly controlled.

[0004] During the enzymatic hydrolysis process, the water-soluble fertilizer in the enzymatic hydrolysis tank needs to be sampled and the hydrolysis degree measured every 20-30 minutes. During the existing sampling operation, it is difficult to completely expel the air in the sampling tube, and a small amount of air will remain in the sampling tube. It usually takes 10-15 minutes from the completion of sampling to the sample delivery for inspection. The dissolved oxygen content of the sample will increase, and the sample hydrolysis degree detection will produce errors, which is not conducive to the monitoring of the enzymatic hydrolysis process.

[0020] refer to Figures 1-6 , add earthworm slurry and water into the enzymolysis tank 1 from the feeding port on the top of the enzymolysis tank 1, with the volume ratio of earthworm slurry to water being 1:5; taking 10kg of earthworm slurry as an example, 50kg of water needs to be added; start the stirring mechanism in the enzymolysis tank 1 for stirring (200rpm); keep the enzymolysis tank 1 at a constant temperature of 50°C, and then inject the neutral protease solution; introduce nitrogen into the top of the enzymolysis tank 1 to disperse the air, reduce the gas phase oxygen concentration in the enzymolysis tank 1, and maintain a positive pressure in the enzymolysis tank 1; introduce nitrogen into the bottom of the enzymolysis tank 1 through a microporous aeration pipe to form a gas circulation, homogenize the material and control oxygen; when sampling and testing are required, such as Figure 7 As shown, the sampler 6 is inserted into the sampling head 4 and docked with the sampling head 4. At this time, the left side wall of the sealing ring 8 fits with the right side wall of the sampling head 4, and the pre-tightening force applied by the spring 1 can make the sealing ring 8 fit tightly with the sampling head 4 to ensure the sealing between the sampling head 4 and the sampler 6, and the sampler 6 is relatively fixed to the sampling head 4, and the feed port 7 is aligned with the bottom end of the channel 1 5; then the driving mechanism drives the sampling head 4 and the sampler 6 to move synchronously toward the inside of the enzymolysis tank 1; after the sampling head 4 moves a short distance, the top of the channel 1 5 is connected to the gas injection mechanism; the gas injection mechanism injects the protective gas nitrogen at the top of the enzymolysis tank 1 into the sampler 6 through the channel 1 5 and the feed port 7, and the air in the sampler 6 is squeezed out from the exhaust mechanism; at this time, the gas environment in the channel 1 5, the feed port 7 and the sampler 6 is in the same state as the gas environment in the enzymolysis tank 1; then the driving mechanism drives the sampling head 4 and the sampler 6 to continue to move toward the inside of the enzymolysis tank 1, as shown Figure 9As shown, until the top of channel 1 5 moves into the enzymolysis tank 1, and then the sample slurry enters the sampler 6 from channel 1 5 through the feed port 7; after the sampling is completed, the driving mechanism drives the sampling head 4 and the sampler 6 to move outward to Figure 7 Then remove the sampler 6 from the sampling head 4, seal the feed port 7 again with the sealing ring 8, and then send the sample in the sampler 6 for inspection; Figure 4 As shown, the middle section of channel 1-5 is set to be inclined. After the sampler 6 is separated from the sampling head 4, the slurry remaining in channel 1-5 will flow out of channel 1-5, avoiding the slurry remaining in channel 1-5 and affecting the next sampling. After each sampling, channel 1-5 can be rinsed with clean water to keep channel 1-5 better clean. The present invention is provided with the sampling head 4, sampler 6, sealing ring 8, exhaust mechanism, gas injection mechanism and driving mechanism. After the sampling head 4 and the sampler 6 are docked, the sealing ring 8 can ensure the seal between the sampling head 4 and the sampler 6. During the process of the driving mechanism driving the sampling head 4 to move into the enzymolysis tank 1, the gas injection mechanism injects the protective gas on the top of the enzymolysis tank 1 into the sampler 6 and squeezes out the air in the sampler 6 through the exhaust mechanism, so that the gas environment in the sampler 6 is in the same state as the gas environment in the enzymolysis tank 1, avoiding the increase of dissolved oxygen content after the sample sent for inspection enters the sampler 6, thereby ensuring the accuracy of sample detection.

[0021] Specifically, such as Figure 2-Figure 4 As shown, a piston 9 is slidably installed in the sampler 6, and the piston 9 is fixedly connected to a return spring 26, and the return spring 26 is fixedly connected to the sampler 6 at one end away from the piston 9; a limiting mechanism is provided on the side of the piston 9, and the limiting mechanism is used to limit the piston 9, and can cancel the limitation of the piston 9 when the sampling head 4 moves into the enzymatic hydrolysis tank 1; the limiting mechanism includes a clamping block 15, and the clamping block 15 is rotatably connected to the sampler 6; a traction rope 17 is fixedly connected to the clamping block 15, and the traction rope 17 is fixedly connected to a slide rod 16 at one end away from the clamping block 15, and the slide rod 16 is slidably connected to the sampler 6.

[0022] refer to Figure 2 and Figure 4 In the initial state, the left side wall of the piston 9 is in contact with the inner wall of the sampler 6, which can reduce the amount of air in the sampler 6; the return spring 26 is in a stretched state, and the block 15 limits the piston 9, so that the piston 9 remains in the Figure 4 When the sampling head 4 and the sampler 6 move to the position shown; Figure 8When in the position shown, the left end of the slide bar 16 is close to the right side wall of the cylindrical cam 18; when the sampling head 4 and the sampler 6 continue to move toward the inside of the enzymolysis tank 1, the slide bar 16 moves to contact with the cylindrical cam 18, and then the slide bar 16 moves to the right relative to the sampler 6. The slide bar 16 drives the block 15 to rotate upward through the traction rope 17, and the block 15 cancels the limit on the piston 9; the elastic potential energy of the reset spring 26 is released, driving the piston 9 to move to the right, and a negative pressure is formed in the left chamber of the piston 9 in the sampler 6. When the sampling head 4 drives the top of the channel 1 5 to move into the enzymolysis tank 1, the slurry quickly enters the sampler 6 under the action of the negative pressure, thereby improving the sampling efficiency.

[0023] Specifically, such as Figure 3-Figure 5 As shown, the exhaust mechanism includes a channel 2 10, which is opened on the inner side of the piston 9. A block 11 is elastically and slidably connected to the channel 2 10. A push rod 12 for driving the block 11 to move is provided on the side of the block 11, and the push rod 12 is fixedly connected to the sampler 6; the block 11 is set to a frustum shape, and the channel 2 10 is set to a frustum shape matching the block 11 at one end close to the block 11.

[0024] refer to Figure 5 When the left side wall of the piston 9 is in contact with the inner wall of the sampler 6, the push rod 12 acts on the block 11, and the channel 2 10 is in an open state. When the gas injection mechanism injects the protective gas in the enzymolysis tank 1 into the channel 1 5 and the sampler 6, the air in the channel 1 5 and the sampler 6 is discharged from the channel 2 10; before the sampling head 4 enters the enzymolysis tank 1, the block 15 cancels the limit on the piston 9. After the piston 9 moves to the right, the block 11 moves to the left under the elastic force of the spring 2 connected thereto to block the left end of the channel 2 10; the left ends of the block 11 and the channel 2 10 are both set to a frustum shape, and the left end is small and the right end is large. The elastic force of the spring 2 combined with the air pressure can make the block 11 tightly block the channel 2 10, preventing air from entering the sampler 6 and contaminating the sample.

[0025] Specifically, such as Figure 3 and Figure 4 As shown, a slot 13 is provided on the sampling head 4, and an insert block 14 that can be plugged into the slot 13 is fixedly connected to the sampler 6; the insert block 14 and the slot 13 are both set to be rectangular, and the positioning of the sampler 6 can be achieved by plugging the insert block 14 into the slot 13. A magnetic part (such as a magnet) can be provided at the docking end of the sampling head 4 and the sampler 6, and the relative fixation of the sampling head 4 and the sampler 6 is achieved by the mutual attraction of the magnetic poles and the limitation of the insert block 14.

[0026] Specifically, such as Figure 2-Figure 4 and Figure 6As shown, the driving mechanism includes a cylindrical cam 18, which is coaxially arranged with the sampling head 4 and rotatably mounted on the inner side of the sampling port 2; a slide groove 19 is provided on the inner side wall of the cylindrical cam 18, and a slide post 20 that can slide with the slide groove 19 is fixedly connected to the side wall of the sampling head 4; a gear 1 23 is fixedly connected to the outer side wall of the cylindrical cam 18, and the gear 1 23 is meshed with the gear 2 24, and a motor 25 for driving the gear 2 24 to rotate is provided on the side; the motor 25 drives the gear 1 23 to rotate through the gear 2 24, and the gear 1 23 drives the cylindrical cam 18 to rotate, and the cylindrical cam 18 drives the sampling head 4 to reciprocate in the horizontal direction through the cooperation of the slide groove 19 and the slide post 20.

[0027] Specifically, such as Figure 3 and Figure 4 As shown, the gas injection mechanism includes an air pipe 21; one end of the air pipe 21 is connected to the top of the enzymolysis tank 1, and the other end is located in the sampling port 2 and can be connected to the channel 1-5; a pump body 22 is provided in the middle of the air pipe 21; when the sampling head 4 moves toward the inside of the enzymolysis tank 1 until the channel 1-5 is aligned with the bottom end of the air pipe 21, the pump body 22 slowly pumps the protective gas on the top of the enzymolysis tank 1 into the channel 1-5, so that the channel 1-5 and the sampler 6 are filled with protective gas, so that the gas environment in the sampler 6 is in the same state as the gas environment in the enzymolysis tank 1.
