Description

Technical Field

[0001] The invention relates to the technical field of nutrient solution fermentation, in particular to horizontal type continuous production liquid nutrient solution fermentation equipment. Background Art

[0002] Plant organic nutrient solution is a liquid fertilizer formed by fermentation and decomposition of natural and organic materials. It is rich in various organic matter and trace elements, such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, etc., as well as some organic substances, etc. These ingredients play an important role in promoting the growth and development of plants. At present, the amount of vegetable leaf garbage in my country's vegetable markets every day is huge. From the perspective of its composition, more than 95% are leaves, stems, roots, etc. that are easy to ferment and rot. Its water content is relatively high, and its main nutrients are in its liquid, which is a good fertilizer resource. However, its easy corruption problem makes it impossible to store it for a long time and reuse it. Fermenting it into plant organic nutrient solution can effectively avoid the above problems.

[0003] A horizontal fermentation tank is disclosed in Chinese invention patent CN112725151B. Although it has advantages over the prior art in terms of shock absorption, enhanced stirring strength, and the ability to scrape dirt off the inner wall, solid materials take up a large amount of space after entering the fermentation tank, reducing the production efficiency of the liquid nutrient solution. In addition, the fermented materials are not easily completely discharged from the inside of the fermentation tank, making it difficult to clean the inside of the fermentation tank. The residual materials will also affect the subsequent fermentation process. Summary of the invention

[0015] Compared with the prior art, the present invention provides a horizontal continuous production liquid nutrient solution fermentation equipment, which has the following beneficial effects: 1. The horizontal continuous production liquid nutrient solution fermentation equipment can continuously provide vegetable juice to the inside of the fermentation box by setting a spiral extrusion dehydration component, so that the liquid inside the fermentation box can be continuously fermented, which is convenient for the continuous production of nutrient solution. At the same time, after filtering through the filter net, impurities in the liquid can be screened out in advance to prevent solids from entering the fermentation box and causing precipitation accumulation.

[0016] 2. The horizontal continuous production liquid nutrient solution fermentation equipment is equipped with a spiral extrusion dehydration component and a bulk material component. After the vegetable leaves are dehydrated, the dehydrated solids can be discharged through a transport cylinder.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For an embodiment of the present invention, please refer to Figures 1 to 12 , including a liquid collecting box 1, a material collecting box 2 and a fermentation box 6, the fermentation box 6 is divided into a heating box on the left and a low-temperature box on the right, the heating box and the low-temperature box are both provided with a cover door 603 on the top, and an exhaust valve 604 is provided on the cover door 603, the liquid collecting box 1 and the heating box, as well as the heating box and the low-temperature box are connected through a one-way valve 601 to ensure that the liquid collected in the liquid collecting box 1 continuously enters the fermentation box 6, and a drain port 7 is provided in the middle of the right side of the fermentation box 6; When the juice collected in the liquid collecting box 1 gradually enters the fermentation box 6, the fermented nutrient solution in the fermentation box 6 will also be gradually discharged from the drain port 7, thereby achieving the purpose of continuous production of nutrient solution.

[0024] like Figure 1As shown, a spiral extrusion dehydration component 4 is arranged on the top of the liquid collecting box 1, and a bulk material component 3 is arranged on the top of the material receiving box 2. The bulk material component 3 and the spiral extrusion dehydration component 4 are driven together by a motor 5 on the right side of the spiral extrusion dehydration component 4. A reduction component 9 is arranged on the left side of the bulk material component 3. The output shaft of the reduction component 9 drives the material receiving component inside the material receiving box 2 to circulate and collect materials. like Figure 10-12 As shown, the spiral extrusion dehydration assembly 4 includes a dehydration cylinder 401 and a variable pitch screw 407, the diameter of one end of the variable pitch screw 407 close to the motor 5 is larger than the diameter of the other end, the pitch of the variable pitch screw 407 close to the motor 5 is larger than the pitch of the other end, the inner cavity of the dehydration cylinder 401 is truncated cone-shaped, and the inner wall of the dehydration cylinder 401 is matched with the outer contour of the variable pitch screw 407; like Fig.10 and Fig.11 As shown, the side wall array of the dehydration cylinder 401 is provided with drainage holes 403 for facilitating the discharge of the internal liquid, the top of the dehydration cylinder 401 near the motor 5 is provided with a feed port 402, and the end of the dehydration cylinder 401 away from the motor 5 is provided with an annular cutting hole 408 through cutting knives distributed in an annular array; The working principle of the spiral extrusion dehydration component 4 is the same as that of the spiral extrusion dehydrator. The moisture in the material is squeezed out by reducing the space. At the same time, the dehydrated solid material is squeezed out and falls evenly under the action of the bulk material component 3. Finally, the falling material is collected by the collecting component inside the collecting box 2.

[0025] like Figure 3-Figure 7 As shown, the bulk material assembly 3 includes a transport cylinder 301 and an auger 302. The bottom of the transport cylinder 301 is provided with equally spaced material leakage inclined holes 303. The material receiving assembly includes an axle 905 arranged on the inner wall of the material receiving box 2 through a bearing. Two driving wheels 203 are symmetrically arranged on the axle 905. The outside of the driving wheel 203 drives the equally spaced rotating blocks 204 to rotate through the transmission member 202. The inside of the rotating block 204 is movably connected with a bearing shaft 213 through a bearing block 212. The inner end of the bearing shaft 213 is detachably installed with a receiving shell 201 for receiving the dry material after dehydration. When the material is transported by the auger 302 inside the transport cylinder 301, the material moves inside the transport cylinder 301. Since the leakage inclined hole 303 is inclined, part of the material will be discharged from the leakage inclined hole 303 when passing through the leakage inclined hole 303, so that the solid material is evenly dispersed after passing through the bulk material component 3, and the fallen material can be collected by the collecting shell 201.

[0026] like Figure 4-Figure 7As shown, a material control box 211 is provided at the bottom of the transport cylinder 301, and a downward pressure rod 208 is movably inserted inside the material control box 211, and a downward pressure portion cooperating with the load-bearing shaft 213 is provided on the bottom side of the downward pressure rod 208, and a spring frame 205 is provided on the side wall of the material receiving box 2, and the interior of the spring frame 205 is connected to the bottom of the downward pressure rod 208 through a compression spring 207, and an insertion rod 206 inserted downward into the spring frame 205 is provided at the bottom of the downward pressure rod 208, and an elastic sheet 209 is provided on the inner wall of the material receiving box 2 at the middle part of the downward pressure rod 208, and a toggle portion 210 cooperating with the elastic sheet 209 is provided on the outer side of the middle part of the downward pressure rod 208.

[0027] When the material falling from the bulk material assembly 3 is collected by the material collecting shell 201, as the weight of the material collecting shell 201 gradually increases, the load-bearing shaft 213 gradually applies gravity to the pressing rod 208. After the pressing force of the pressing rod 208 is able to compress the compression spring 207, the toggle portion 210 can be used to apply pressure to the elastic sheet 209 until the elastic sheet 209 is deformed and no longer blocks the toggle portion 210. At this time, the force applied to the elastic sheet 209 suddenly acts on the compression spring 207, causing the elastic sheet 209 to be suddenly compressed again.

[0028] like Fig.10 As shown, the left and right side walls of the top of the liquid collecting box 1 are both provided with arc rails 406, and a screen frame 405 is slidably provided inside the arc rails 406. The middle part of the screen frame 405 is provided with a filter screen 404, and the filter screen 404 is provided directly below the spiral extrusion dehydration component 4.

[0029] After the spiral extrusion dehydration assembly 4 discharges the juice, the juice is filtered by the spiral extrusion dehydration assembly 4. When the filter screen 404 is to be cleaned or replaced, the screen frame 405 can be pulled out.

[0030] like Figure 2 As shown, the inner bottom wall of the liquid collecting tank 1 is provided with a controller 101 and an electric furnace 102, a maintenance door for protecting the internal equipment is provided in the middle of the front side of the liquid collecting tank 1, a heating rod 103 is provided on the inner bottom wall of the heating box, a monitor for feedback of water temperature is provided inside the heating box, the operation of the heating rod 103 is controlled to keep the inside of the heating box at a constant temperature, the right side of the electric furnace 102 is connected to the heating rod 103 through a heating pipe, and the top of the liquid collecting tank 1 is provided with an inclined surface for facilitating liquid convergence, so that the collected liquid can enter the heating box from the one-way valve 601.

[0031] The discharged juice falls directly after being filtered by the filter net 404, and is collected on the side close to the fermentation box 6 after being collected on the inclined surface. After the liquid level of the juice inside the collecting box 1 is greater than the liquid level inside the fermentation box 6, the juice will flow into the interior of the fermentation box 6, and the raw materials required for fermentation are added by opening the cover door 603. Then, the internal solution is heated by the heating rod 103 to reach the most suitable temperature for fermentation. At the same time, the feedback water temperature monitor set inside the heating box feeds back the temperature to the controller 101, and then controls the operation of the heating rod 103 to keep the inside of the heating box at a constant temperature. While the liquid inside the fermentation box 6 is fermenting, due to the continuous addition of juice, the liquid level gradually rises to above the discharge port 7, and the fermented nutrient solution inside the fermentation box 6 is automatically discharged, thereby achieving the purpose of continuous production of nutrient solution.

[0032] like Figure 6 and Figure 7 As shown, a return elastic member 215 is arranged inside the rotating block 204, and the end of the return elastic member 215 pushes the bearing block 212 toward the end away from the conveying member 202. The inner end of the load-bearing shaft 213 is provided with an arc-shaped mounting plate 214 through a connecting portion, and both ends of the material receiving shell 201 are provided with mounting shafts 217 installed inside the mounting plate 214.

[0033] Since there is a connection part between the load-bearing shaft 213 and the placement plate 214, and a bearing is provided between the load-bearing shaft 213 and the bearing block 212, it can be ensured that the opening of the material receiving shell 201 is always upward when it moves with the bearing block 212, which is convenient for receiving and storing materials.

[0034] like Figure 5 and Fig. 9 As shown, the bottom wall of the transport cylinder 301 is symmetrically provided with two arc-shaped grooves 305, and the interior of the arc-shaped grooves 305 is provided with arc-shaped plates 306. The bottoms of the two arc-shaped plates 306 are respectively connected with inner arc plates 307 and outer arc plates 308. The two arc-shaped plates 306 are hinged to the top of the lower pressure rod 208 through a pull rod 304. The middle part of the lower pressure rod 208 is provided with a limiting portion 216 for preventing the lower pressure rod 208 from being excessively inserted into the material control box 211.

[0035] As the pressing rod 208 is gradually pressed downward, since the top of the pressing rod 208 is connected to the arc plate 306 through the pull rod 304, the arc plate 306 will gradually converge the inner arc plate 307 and the outer arc plate 308. When the elastic sheet 209 is deformed and no longer blocks the toggle portion 210, the arc plate 306 will also be suddenly pulled down to the lowest point. At this time, the inner arc plate 307 and the outer arc plate 308 overlap inside the arc groove 305 and close the inclined hole 303 for material leakage, to prevent the material from continuing to fall when the collecting shell 201 is replaced.

[0036] like Fig. 9As shown, a cylinder 801 is disposed in the side wall of the material control box 211, a counterweight block 802 is disposed at the end of the piston rod extending downwardly of the cylinder 801, and a one-way air inlet valve 803 and a flow-limiting air outlet valve 804 are respectively connected to the top of the cylinder 801 through two air pipes; When the lower pressure rod 208 falls to close the leakage inclined hole 303, the counterweight block 802 can pull out the piston rod, and air enters the cylinder 801 through the one-way air intake valve 803. In the final stage when the lower pressure rod 208 is pushed upward by the compression spring 207, the limiting part 216 presses the counterweight block 802 upward to allow the gas inside the cylinder 801 to be slowly discharged from the flow limiting air outlet valve 804, preventing the leakage inclined hole 303 from opening when the material receiving shell 201 is not in place, thereby avoiding the problem of material leakage.

[0037] After the material receiving shell 201 filled with materials moves, the pressing rod 208 will move upward under the action of the compression spring 207. However, since the gas inside the cylinder 801 cannot be discharged suddenly, the material leakage inclined hole 303 will not open suddenly, preventing the material leakage inclined hole 303 from opening when the material receiving shell 201 is not in place.

[0038] like Figure 7 and Figure 8 As shown, the reduction assembly 9 includes a gear box 901 and a reduction gear set 902 therein. The last gear of the reduction gear set 902 is meshed with a gear ring 903. The interior of the gear ring 903 is mounted on the left outer wall of the material receiving box 2 through a bearing. The inner wall of the gear ring 903 is provided with an inner clamping plate 912 in a ring array. A coil spring 904 is provided at the end of the wheel axle 905. The outer end of the coil spring 904 is provided with an end clamping plate 911 that cooperates with the inner clamping plate 912.

[0039] The gears inside the gear box 901 rotate to store energy in the coil spring 904, and the rotation of the variable pitch screw rod 407 drives the gears inside the gear box 901 to rotate, so that the gear ring 903 rotates. The coil spring 904 stores elastic potential energy, and with the cooperation of the end clamping plate 911 and the inner clamping plate 912, when the energy stored in the coil spring 904 is gradually reduced, Figure 8 As shown, the end clamping plate 911 will detach from the inner clamping plate 912, jump to the next inner clamping plate 912 and then clamp again, so as to prevent too much force on the coil spring 904 and ensure that the coil spring 904 provides torque for the axle 905 when the axle 905 rotates.

[0040] like Figure 7 As shown, a movable groove 908 is opened in the middle of the inner wall of the material receiving box 2, and a rotating rod 909 is movably arranged inside the movable groove 908 through a pin shaft. The outer end of the rotating rod 909 cooperates with the insertion rod 206, and the inner end of the rotating rod 909 is provided with a braking part 910.

[0041] like Figure 7 and Figure 8 As shown, the part of the wheel axle 905 located in the side wall of the material receiving box 2 is provided with a brake disc 906, the top of the brake disc 906 is located in the middle of the movable groove 908, and the outer side of the brake disc 906 is provided with a brake block 907 that cooperates with the brake part 910.

[0042] When the rotating rod 909 is pressed down by the insertion rod 206 to move the braking part 910 upward, the braking part 910 will release the braking block 907, allowing the braking disc 906 to rotate freely. Since there is material inside the material receiving shell 201 in a row on the inner side of the material receiving box 2, when the braking disc 906 can rotate, the material receiving shell 201 on the top will definitely rotate toward the inside of the material receiving box 2, so that the material receiving shell 201 without material on the outside will rotate to the top. When the material receiving shell 201 rotates, since the pressing rod 208 is no longer affected by the gravity of the material receiving shell 201, it will rebound under the action of the compression spring 207, causing the braking part 910 to fall again, and when the next material receiving shell 201 rotates to the top, it will just block the braking block 907, so that the material receiving shell 201 stays directly below the bulk material assembly 3.

[0043] The specific steps and principles of using this device are as follows: First, the controller 101 inside the liquid collecting box 1 controls the motor 5 to work, and the collected vegetable leaves are put into the feed port 402. The vegetable leaves are transported by the variable pitch screw 407 and the water in the vegetable leaves is squeezed out by space compression, so that the water is discharged through the drainage hole 403 on the side wall of the dehydration cylinder 401; like Figure 2 As shown, the discharged juice falls directly after being filtered by the filter screen 404, and is collected on the side close to the fermentation box 6 after being collected on the inclined surface. After the liquid level of the juice inside the liquid collecting box 1 is greater than the liquid level inside the fermentation box 6, the juice will flow into the inside of the fermentation box 6, and the raw materials required for fermentation are added by opening the cover door 603. Then, the internal solution is heated by the heating rod 103 to reach the most suitable temperature for fermentation. At the same time, the feedback water temperature monitor set inside the heating box feeds back the temperature to the controller 101, and then the heating rod 103 is controlled to keep the temperature inside the heating box constant. While the liquid inside the fermentation box 6 is fermenting, due to the continuous addition of juice, the liquid level gradually rises to above the drain port 7, and the fermented nutrient solution inside the fermentation box 6 is automatically discharged, thereby achieving the purpose of continuous production of nutrient solution. While the vegetable leaves inside the dehydration cylinder 401 are being dehydrated, Fig.11 As shown, due to the continuous transportation of the variable pitch screw 407, the vegetable leaves are gradually pressed against the cutting hole 408, and after strong squeezing, the dehydrated vegetable leaves are squeezed out, and the discharged solid materials become muddy; After the muddy material enters the transport cylinder 301, Figure 5As shown, the muddy material gradually approaches the auger 302. After being transported by the auger 302, the muddy material moves inside the transport cylinder 301. Since the material leakage inclined hole 303 is inclined, part of the material will be discharged from the material leakage inclined hole 303 when passing through the material leakage inclined hole 303, so that the solid material is evenly dispersed after passing through the bulk material assembly 3. The scattered muddy materials will be directly collected by the collecting shell 201. For the vegetable leaves that have been dehydrated once, some clean water can be added to the inside of the collecting shell 201 in advance, and the materials can be soaked in the clean water to make them mixed into a muddy state inside the collecting shell 201. The nutrients inside can also be extracted again by soaking, and then the materials soaked into a muddy state are poured into the feed port 402 again for dehydration. After the materials that have been dehydrated twice or multiple times fall into the collecting shell 201, they can be transported to other places to be made into solid fertilizers. When the material collecting shell 201 is used to collect the materials falling from the bulk material assembly 3, as the weight of the material collecting shell 201 gradually increases, the return elastic member 215 will also be gradually compressed, so that the load-bearing shaft 213 applies gravity to the lower pressing rod 208. After the downward pressure of the lower pressing rod 208 can compress the compression spring 207, the toggle portion 210 can be used to apply pressure to the elastic sheet 209 until the elastic sheet 209 is deformed and no longer blocks the toggle portion 210. At this time, the force applied to the elastic sheet 209 suddenly acts on the compression spring 207, causing the elastic sheet 209 to suddenly compress again, which will cause the bottom of the insertion rod 206 to suddenly press the end of the rotating rod 909, causing the braking portion 910 to tilt upward and no longer block the brake block 907, so that the brake disc 906 can rotate freely. At the same time, since there are materials inside the material receiving shells 201 in a row inside the material receiving box 2, when the brake disc 906 can rotate, the material receiving shell 201 at the top will definitely rotate toward the inside of the material receiving box 2, so that the material receiving shell 201 without materials on the outside rotates to the top. When the material receiving shell 201 rotates, since the lower pressing rod 208 is no longer subjected to the gravity of the material receiving shell 201, it will rebound under the action of the compression spring 207, causing the braking part 910 to fall again, and when the next material receiving shell 201 rotates to the top, it will just block the brake block 907, so that the material receiving shell 201 stays just below the bulk material assembly 3; When the pressing rod 208 is gradually pressed down, since the top of the pressing rod 208 is connected to the arc plate 306 through the pull rod 304, the arc plate 306 will gradually converge the inner arc plate 307 and the outer arc plate 308. When the elastic sheet 209 is deformed and no longer blocks the toggle portion 210, the arc plate 306 will also be suddenly pulled down to the lowest point. At this time, the inner arc plate 307 and the outer arc plate 308 overlap inside the arc groove 305 and close the material leakage inclined hole 303 to prevent the material from continuing to fall when the material receiving shell 201 is replaced. After the material receiving shell 201 filled with materials moves, the pressing rod 208 will move upward under the action of the compression spring 207, but because the gas inside the cylinder 801 cannot be suddenly discharged, the material leakage inclined hole 303 will not suddenly open, preventing the material leakage inclined hole 303 from opening when the material receiving shell 201 is not in place. like Fig. 9 As shown, when the lower pressure rod 208 falls to close the material leakage inclined hole 303, the counterweight block 802 can pull out the piston rod, and air enters the cylinder 801 through the one-way air inlet valve 803. In the final stage when the lower pressure rod 208 is pushed upward by the compression spring 207, the limiting part 216 presses the counterweight block 802 upward to allow the gas in the cylinder 801 to be slowly discharged from the flow-limiting air outlet valve 804, thereby preventing the material leakage inclined hole 303 from opening when the material receiving shell 201 is not in place, thereby avoiding the problem of material leakage. In another embodiment, the gears inside the gear box 901 rotate to store energy in the coil spring 904, and the rotation of the variable pitch screw rod 407 drives the gears inside the gear box 901 to rotate, so that the gear ring 903 rotates. The coil spring 904 stores elastic potential energy, and with the cooperation of the end clamping plate 911 and the inner clamping plate 912, when the energy stored in the coil spring 904 is gradually reduced, Figure 8 As shown, the end clamping plate 911 will detach from the inner clamping plate 912, jump to the next inner clamping plate 912 and then clamp again, so as to prevent too much force on the coil spring 904 and ensure that the coil spring 904 provides torque for the axle 905 when the axle 905 rotates.
