Description

Technical Field

[0001] The invention relates to the technical field of liquid fertilizer production, and in particular to a device and method for producing biological liquid fertilizer by utilizing vinegar dregs. Background Art

[0002] Liquid fertilizer is also called liquid fertilizer. It includes fertilizer in solution state and fertilizer containing suspension of solid particles.

[0003] Vinegar dregs, the residue left after making vinegar from rice, wheat, sorghum, and other crops, are rich in trace elements such as iron, zinc, selenium, and manganese. Therefore, using vinegar dregs to make liquid fertilizer can be a waste-recycling process. Fermentation tanks are used in the production process.

[0004] The fermentation process of existing liquid fertilizer production is often completed in a fermentation tank. After adding materials to the fermentation tank, they are stirred evenly for fermentation. The fermentation tank containing the materials is equipped with a heating device and a temperature control device. The temperature control device controls the heating device to adjust the temperature through the temperature signal sensed by the temperature sensor in the fermentation tank.

[0005] However, existing heating devices are generally installed on the walls of the fermentation tank. This heating method transfers heat gradually inward from the outer layer of the material in contact with the tank wall, resulting in an uneven temperature decrease from the outside to the inside of the material. This leads to uneven fermentation of the material, requiring frequent stirring to adjust the fermentation uniformity, which in turn increases the fermentation time. Therefore, the applicant has developed a new technical solution in actual production to solve the above technical problems. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: A device for producing bio-liquid fertilizer using vinegar dregs, such as Figure 1 and Figure 2 , including a fermentation tank 1 with an upward opening and a cover plate 11 detachably connected to the fermentation tank 1 and closing the fermentation tank 1, and also including a heating device, the fermentation tank 1 is a hollow cylinder, the heating device includes a heating rod 12 arranged on the cover plate 11 and a heater arranged on the side wall of the fermentation tank 1, the heater adopts an existing structure, so it is not drawn in the figure, and reference can be made to the heater in the organic fertilizer fermentation tank 1 with uniform temperature in CN201420603677.X;

[0036] like Figure 1 and Figure 2 and Figure 3The cover 11 is rotatably connected with a swivel 13. The swivel 13 is provided with a baffle 14 on the side facing away from the cover 11 and extending into the fermentation tank 1. One side of the baffle 14 extends out of the side wall of the swivel 13 and is fixedly connected to the lower end face of the cover 11. One end of the heating rod 12 is fixedly arranged on the annular surface of the swivel 13, and the heating rod 12 gradually extends downward from the annular surface of the swivel 13. At this time, the end of the heating rod 12 fixed to the annular surface of the swivel 13 is distributed close to the side wall of the swivel 13, so that the heating rod 12 is in the fermentation tank. 1 is obliquely distributed, the baffle 14 is provided with an arc groove 141 for the heating rod 12 to pass through, and the cover plate 11 is provided with a power member for driving the rotating ring 13 to rotate. At this time, the power member drives the rotating ring 13 to rotate, so that the rotating ring 13 drives the inclined heating rod 12 to move, so that the heating position of the heating rod 12 on the material in the fermentation tank 1 is changed, reducing the occurrence of uneven temperature of the material in the fermentation tank 1 from the outside to the inside, improving the uniformity of heating of the material in the fermentation tank 1, and improving the fermentation efficiency.

[0037] The temperature rise control of the heating device can be controlled by a temperature control system. At this time, the temperature control system is electrically connected to the temperature sensor 182 and the heating device. The temperature control device controls the heating device to adjust the temperature through the temperature signal sensed by the temperature sensor 182 in the fermentation tank 1.

[0038] like Figure 1 and Figure 2 and Figure 3 When the fermentation tank 1 needs to be heated, the heating device heats the side wall of the fermentation tank 1 through the heater, and heats the material in the fermentation tank 1 through the heating rod 12. The heating rod 12 is tilted and, driven by the power component, moves in the fermentation tank 1 as the rotating ring 13 rotates. That is, when the heating rod 12 rotates with the rotating ring 13, the lower end of the heating rod 12 first approaches the arc groove 141, and then the lower end of the heating rod 12 first passes through the lower part of the arc groove 141, and then the upper end of the heating rod 12 passes through the upper part of the arc groove 141. At this time, the temperature of the material in the fermentation tank 1 not only starts to extend from the inner wall of the fermentation tank 1 to the center, but also gradually heats up from the inside of the material toward the inner wall of the fermentation tank 1 (such as Figure 2 The heating area in the fermentation tank 1 is heated evenly to improve the fermentation efficiency. The battery pack that provides power to the heating rod 12 is a battery pack without wires and is directly installed on the rotating ring 13, which facilitates the heating rod 12 to rotate and heat.

[0039] like Figure 1 and Figure 2 The cover plate 11 is placed at the opening of the fermentation tank 1, that is, the periphery of the cover plate 11 extends out of the outer wall of the fermentation tank 1, and the cover plate 11 is pushed up or down by a cylinder arranged on the outer wall of the fermentation tank 1 or on the ground, thereby opening or closing the fermentation tank 1.

[0040] like Figure 3 and Figure 4 The inner and outer walls of the rotating ring 13 are coaxially connected to a turntable 15 and a drive ring 151. The turntable 15 and the drive ring 151 are respectively provided with a primary stirring member and a secondary stirring member extending into the fermentation tank 1. The power member drives the primary stirring member and the secondary stirring member to stir when the primary stirring member and the secondary stirring member need to stir. At this time, the stirring arrangement of the primary stirring member and the secondary stirring member facilitates stirring the material in the fermentation tank 1 when stirring is required; when stirring is not required, the primary stirring member and the secondary stirring member stop stirring, while the rotating ring 13 continues to rotate, driving the heating rod 12 to heat the material to meet the fermentation temperature of the material.

[0041] like Figure 3 and Figure 4 The main stirring member includes a rotating rod 152 coaxially fixed on the turntable 15, and the two ends of the arc groove 141 extend out of the end surface of the baffle 14 respectively, that is, completely penetrate the baffle 14. At this time, the baffle 14 is divided into two parts. The part completely on the rotating ring 13 is used as the main stirring blade 142, and one side of the main stirring blade 142 is fixed to the outer wall of the rotating rod 152. The other part of the baffle 14 is the secondary stirring blade 143. At this time, the baffle 14 is not fixedly connected to the lower end surface of the cover plate 11. The main stirring blade 142 is distributed along the circumference of the outer wall of the rotating rod 152. Figure 4 FIG. 1 shows the distribution of two adjacent main stirring blades 142 when four main stirring blades 142 are arrayed;

[0042] like Figure 3 and Figure 4 The secondary stirring member includes a plurality of driving rods 153 distributed along the annular surface of the driving ring 151, and the secondary stirring blades 143 are fixed on the driving rods 153. Each driving rod 153 is provided with a secondary stirring blade 143, and each secondary stirring blade 143 is arranged circumferentially along the center line of the driving ring 151. The purpose of this is to facilitate that each driving rod 153 has a secondary stirring blade 143, and one side wall of each secondary stirring blade 143 is in contact with the wall of the fermentation tank 1, so that the secondary stirring blade 143 can stir the material near the wall of the fermentation tank 1 when the driving ring 151 rotates, thereby accelerating the temperature transfer and facilitating the mixing and fermentation of the material.

[0043] like Figure 3 and Figure 4 The main stirring blade 142 and the secondary stirring blade 143 set above will not interfere with the movement of the heating rod 12 when they rotate with the turntable 15 and the driving ring 151 respectively. Figure 5 In addition, the main stirring blades 142 can also be a plurality of stirring rods 144 arranged on the outer wall of the rotating rod 152. At this time, the length direction of the stirring rods 144 distributed from bottom to top shall not extend to the position where the arc grooves 141 are distributed, so as not to interfere with the movement of the heating rod 12.

[0044] like Figure 1 and Figure 2 The cover plate 11 is provided with a driving port 16 for the driving ring 151 to rotate. The outer wall of the driving ring 151 is rotatably connected to the mouth wall of the driving port 16. The outer ring wall of the rotating ring 13 is rotatably connected to the inner ring wall of the driving ring 151. The outer wall of the turntable 15 is rotatably connected to the inner ring wall of the rotating ring 13. The driving ring 151, the rotating ring 13, and the turntable 15 jointly close the driving port 16. The power part includes a motor 17 arranged on the upper end surface of the cover plate 11. A pad block can be provided on the cover plate 11 to install the power supply 17. The motor 17 is located on one side of the driving port 16. The upper end surfaces of the driving ring 151, the rotating ring 13 and the turntable 15 all extend from the upper end of the driving port 16, and the height of the rotating ring 13 is lower than the height of the driving ring 151 and the turntable 15. 13, a ring-shaped active bevel gear 171 is coaxially fixed on the upper end ring surface of the turntable 13. At this time, the ring-shaped active bevel gear 171 means that a hole is opened in the center, and the diameter of the hole is larger than the diameter of the turntable 15, that is, the inner wall of the hole extends to the ring surface of the rotating ring 13, and the outer wall of the turntable 15 and the driving ring 151 are coaxially fixed with a ring-shaped driven bevel gear 172. The ring-shaped driven bevel gear 172 means that it is to be sleeved on the outer wall of the turntable 15 or the driving ring 151. A power rod 173 is coaxially fixed on the rotating shaft of the motor 17. The power rod 173 extends to the drive ring 151, the rotating ring 13 and the upper end of the turntable 15. The power rod 173 is provided with a driving member for driving the active bevel gear 171 and the driven bevel gear 172 to rotate.

[0045] like Figure 1 and Figure 2The power rod 173 is a prismatic rod, and the driving member includes a movable sleeve 174 coaxially sleeved on the outer wall of the power rod 173. The inner wall of the movable sleeve 174 is a prismatic through hole for the prismatic rod to pass through. The purpose of this design is to facilitate the movable sleeve 174 to move back and forth along the length direction of the power rod 173, and when the power rod 173 rotates, it drives the movable sleeve 174 to rotate. Both ends of the movable sleeve 174 are coaxially fixed with a transmission bevel gear 175 meshing with the two driven bevel gears 172. The movable sleeve 174 is a prismatic column, and the outer wall of the movable sleeve 174 is sleeved with a fixed sleeve 176. The inner wall of the fixed sleeve 176 is a prismatic movable hole that cooperates with the prismatic column. The purpose of this design is to move the sleeve 1 74 can move back and forth in the fixed sleeve 176, and the rotation of the movable sleeve 174 can drive the fixed sleeve 176 to rotate together. The upper end surface of the cover plate 11 is fixedly connected to an L-shaped fixing rod 177. The fixing rod 177 extends to the fixed sleeve 176 at one end away from the cover plate 11 and is fixed with a positioning ring 178 that is rotatably connected to the outer wall of the rotating sleeve. At this time, the positioning ring 178 fixes the position of the fixed sleeve 176 so that the fixed sleeve 176 can only rotate. The outer wall of the fixed sleeve 176 is fixedly sleeved with an intermediate bevel gear 179, which is engaged with the active bevel gear 171. The cover plate 11 is provided with an electric component that drives the movable sleeve 174 to move back and forth on the outer wall of the power rod 173.

[0046] like Figure 1 and Figure 2 The electric part includes an electric push rod 19 arranged on the upper end surface of the cover plate 11. A push plate 191 is fixed to one end of the electric push rod 19. The push plate 191 is passed through the outer wall of the power rod 173 and is located on one side of the movable sleeve 174. The push plate 191 is rotatably connected to the side of the movable sleeve 174 toward the side of the movable sleeve 174.

[0047] like Figure 1 and Figure 2 , the working principle of the power part: when only the material in the fermentation tank 1 needs to be heated, the rod part of the electric push rod 19 drives the push plate 191 to move on the power rod 173, and then the push plate 191 drives the movable sleeve 174 to move on the power rod 173, and the movement of the movable sleeve 174 causes the two transmission bevel gears 175 to separate from the two driven bevel gears 172 respectively. At this time, the intermediate bevel gear 179 is engaged with the active bevel gear 171, thereby causing the rotating ring 13 to rotate. The rotation of the rotating ring 13 causes the position of the heating rod 12 in the fermentation tank 1 to change, thereby increasing the uniformity of the temperature heating in the fermentation tank 1;

[0048] like Figure 1 and Figure 2After the fermentation tank 1 has fermented at a certain temperature for a period of time, the material in the fermentation tank 1 needs to be stirred. At this time, the electric push rod 19 drives the push plate 191 to move in the opposite direction, thereby causing the movable sleeve 174 to move in the opposite direction, so that the two transmission bevel gears 175 are respectively engaged with the two driven bevel gears 172, thereby causing the turntable 15 and the drive ring 151 to rotate. At this time, the main stirring member and the secondary stirring member in the fermentation tank 1 begin to stir, and the heating rod 12 is still moving, meeting the use requirements.

[0049] like Figure 6 , an insertion rod 181 is inserted through the opening 18 in the rotating rod 152. The opening 18 is distributed along the length of the rotating rod 152 and passes through the upper and lower ends of the rotating rod 152. The lower end of the insertion rod 181 extends out of the lower end of the rotating rod 152, and a temperature sensor 182 is fixed to the lower end of the insertion rod 181, which facilitates the temperature sensor 182 to enter the material and measure the temperature of the material. The upper end of the insertion rod 181 is provided with a ring handle 183 whose size is larger than the diameter of the rotating rod 152. At this time, the ring handle contacts the upper end of the rotating rod 152, thereby fixing the insertion rod 181 in the insertion hole 18, making it easier for the temperature sensor 182 to detect the temperature. At this time, the fermentation tank 1 can be used in the state where only the rotating ring 13 rotates;

[0050] like Figure 7 Alternatively, the rod 181 in the socket 18 is replaced by a vent tube 184, one end of which is inserted into the rotating rod 152 and the other end is connected to the air pump 185. In this case, the fermentation tank 1 can be used in a state where the primary and secondary stirring members are stirring, which facilitates the introduction of gas into the material to meet the fermentation requirements. At this time, the rod 181 is replaced by the vent tube 184. When the ventilation is completed, the rod 181 can be replaced.

[0051] like Figure 1 and Figure 8When only the rotating ring 13 rotates, in order to limit the rotation of the turntable 15 and the driving ring 151, the movable sleeve 174 is provided with a telescopic rod 192 that contacts the upper end surface of the turntable 15 and the driving ring 151. The upper end surfaces of the turntable 15 and the driving ring 151 are both provided with an entry hole 193 for the lower end of the telescopic rod 192 to enter. The lower end of the telescopic rod 192 is provided with two opposite inclined surfaces 194. The two inclined surfaces 194 are distributed on both sides of the direction in which the telescopic rod 192 moves back and forth with the movable sleeve 174, so that the telescopic rod 192 can be moved out of or into the entry hole 193. When the sleeve 174 drives the two transmission bevel gears 175 to separate from the two driven bevel gears 172 respectively, the lower end of the telescopic rod 192 moves into the entry hole 193, and the inclined surface 194 partially moves into the entry hole 193. When the movable sleeve 174 drives the two transmission bevel gears 175 to engage with the two driven bevel gears 172 respectively, since the inclined surface 194 partially moves into the entry hole 193, the inclined surface 194 gradually compresses and shortens the telescopic rod 192 under the drive of the movement of the movable sleeve 174, thereby facilitating the lower end of the telescopic rod 192 to move out of the entry hole 193.

[0052] like Figure 1 and Figure 8 The structure of the telescopic rod 192 can include a first rod and a second rod, the upper end of the first rod is fixedly connected to the outer wall of the movable sleeve 174, and the lower end is provided with a placement hole for the upper end of the second rod to enter, the bottom of the placement hole is provided with a compression spring and the end of the compression spring away from the bottom of the placement hole is fixedly connected to the upper end of the second rod, the inclined surface 194 is provided at the lower end of the second rod and when the lower end of the second rod moves into the entry hole 193, the compression spring is in a natural state; when the inclined surface 194 at the lower end of the second rod gradually moves out of the entry hole 193 along the hole wall of the entry hole 193, the compression spring is compressed and has an elastic recovery force, which facilitates pushing the lower end of the second rod into the entry hole 193 again.

[0053] Example 2: A production process using the above-mentioned Example 1, the process comprising the following steps:

[0054] S1: Weigh corresponding parts by weight of 30-40 parts of soybean meal, 5-10 parts of vinegar dregs, 10-15 parts of sweet potato starch, 25-35 parts of urea, 4-8 parts of ferrous sulfate, 5-10 parts of zinc sulfate, 20-30 parts of potassium sulfate, and 3-5 parts of sodium selenite, and mix them together to obtain a mixed solution;

[0055] S2: The mixed liquid is placed in the fermentation tank 1 of Example 1, 120-150 parts of water is added, and a fermentation agent is inoculated. After thorough mixing, the mixture is sealed and fermented continuously at 30-40°C for 5 days, with ventilation and stirring every other day during the fermentation process. After the fermentation is completed, the supernatant liquid is obtained, which is the biological liquid fertilizer. Liquid fertilizer made from vinegar dregs provides nutrition for plants, increases and renews soil organic matter content, promotes microbial growth, improves soil permeability, and enhances soil moisture retention, heat preservation, and fertilizer retention.

[0056] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
