Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mixing equipment, in particular to a mixing device and mixing method based on fertilizer production. BACKGROUND

[0002] The mixer is an important equipment for mixing liquid fertilizer and other fluids by stirring device. Its working principle mainly relies on the rotation of the stirring plate to break the static balance of the liquid by mechanical force, so as to promote the uniform mixing of different components and meet the production process requirements for material uniformity.

[0003] However, in the prior art, new liquid fertilizer raw materials need to be continuously added to the mixer or the mixed material needs to be discharged. When the material is added, the liquid level will rise, and when the material is discharged, the liquid level will drop. For example, in order to mix liquid fertilizer with different concentrations, water and fertilizer need to be added multiple times, and the liquid level in the mixer needs to be changed frequently. Most mixers use stirring plates with fixed positions. In the ideal state, that is, when the liquid level is stable, the stirring and mixing can be more efficient. However, when the liquid level changes, if the stirring structure is higher than the liquid level, part of the stirring plate will be separated from the liquid and exposed to the air. These idle stirring plates cannot apply effective stirring force to the liquid, resulting in a significant reduction in stirring efficiency. Conversely, when the stirring plate is excessively submerged, the resistance of the liquid to the stirring plate increases significantly, the stirring intensity is dispersed, and the stirring efficiency is insufficient, resulting in uneven mixing. At the same time, since the stirring plate is fixed in position, it cannot be evenly arranged in the liquid, so it can only stir the liquid at a specific height, making it difficult to fully mix the upper and lower layers of liquid. The upper and lower layers of liquid cannot be fully mixed, and when the liquid level is low, the stirring plate is idle and wastes energy. When the liquid level is high, additional energy is needed to drive a larger volume of liquid, resulting in an increase in equipment operating costs. To solve the above problems, the industry currently mainly uses two coping methods. One is manual adjustment by the operator, who adjusts the stirring plate position manually by observing the liquid level. However, this method relies on manual operation and has the problems of poor timeliness, high labor intensity, and human error. The other is an automatic adjustment scheme that automatically adjusts the stirring plate height by installing a liquid level sensor and an electric lifting device. However, this scheme also has obvious limitations. The accuracy of the liquid level sensor is easily affected by impurities, bubbles and other factors in the liquid fertilizer, leading to misjudgment. The electric lifting device has a complex structure and is prone to failure in the corrosive environment of liquid fertilizer, resulting in high maintenance costs and being unable to meet the mixing requirements.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0034] Example one, refer to Figures 1-9For the first embodiment of the present application, a mixing device based on fertilizer production is provided, comprising a mixing tank 1, further comprising a motor 2 fixedly connected to the top end of the mixing tank 1, a rotating shaft 3 fixedly connected to the output end of the motor 2, a guide sleeve 4 fixedly connected to the middle part of the rotating shaft 3, an inner tube 5 slidably connected to the inside of the top end of the mixing tank 1, a liquid float plate 6 slidably connected to the outside of the rotating shaft 3, a sliding rod 7 arranged in the inside of the rotating shaft 3, a plurality of stirring blades 8 rotatably connected to the inside of the sliding rod 7, a push-pull rod 9 hingedly connected to the top of the stirring blade 8, a sliding sleeve 10 slidably connected to the outside of the guide sleeve 4, and a connecting rod 11 hingedly connected between the sliding rod 7 and the sliding sleeve 10. The sliding rod 7 is arranged in two and symmetrical about the horizontal central axis of the guide sleeve 4, the upper sliding rod 7 is hingedly connected to the bottom of the liquid float plate 6, the middle part of the push-pull rod 9 is located in the inside of the rotating shaft 3, the number of the push-pull rod 9 is equal to that of the sliding rod 7 and is located above it, and the sliding sleeve 10 is arranged in two and symmetrical about the vertical central axis of the guide sleeve 4. When the liquid level changes, the liquid float plate 6 makes the sliding rod 7 uniformly distributed in the liquid, and the upper sliding rod 7 drives the plurality of stirring blades 8 to rotate.

[0035] Specifically, the mixing tank 1 is a basic container for carrying liquid fertilizer, the output end of the motor 2 outputs power to the rotating shaft 3, the sliding rod 7 and the stirring blade 8 constitute a stirring assembly, the liquid float plate 6 is slidably connected to the outside of the rotating shaft 3, and when the liquid level rises, the liquid float plate 6 slides upward along the rotating shaft 3 under the action of buoyancy, and when the liquid level falls, it moves downward accordingly, thereby bringing the entire stirring assembly and the liquid level to dynamically adapt. The two sliding rods 7 are located above and below the guide sleeve 4, and the upper sliding rod 7 is hingedly connected to the bottom of the liquid float plate 6, so that when the liquid float plate 6 moves, the sliding rod 7 moves in the liquid accordingly and always maintains uniform distribution. A plurality of stirring blades 8 are arranged on the sliding rod 7, so that the liquid fertilizer can be effectively mixed. In addition, when the sliding rod 7 moves up and down, it drives the push-pull rod 9 to adjust the angle of the stirring blade 8. When the liquid level is low, the push-pull rod 9 keeps the stirring blade 8 at an appropriate inclination angle to avoid idling and reduce energy waste. When the liquid level is high, the stirring blade 8 increases the force mixing surface and strengthens the mixing force.

[0036] Among them, the mixing tank 1 is provided with an inlet and outlet.

[0037] Referring to Figures 1-8 The guide sleeve 4 includes a sleeve ring 41 fixedly connected to the middle part of the rotating shaft 3, two circular rods 42 symmetrically arranged and fixedly connected to the outside of the sleeve ring 41, a plurality of vertical plates 43 arranged on the upper and lower sides of the sleeve ring 41, and the sliding sleeve 10 slidably connected to the outside of the circular rod 42.

[0038] Specifically, the sleeve ring 41 is fixed outside the rotating shaft 3 by screws, so that the sleeve ring 41 is tightly attached to the outer surface of the rotating shaft 3, ensuring that the two will not displace relative to each other under high-speed rotating conditions. Two circular rods 42 are symmetrically arranged outside the sleeve ring 41, and a circular groove is formed in the inner wall of the sliding sleeve 10 to match the circular rod 42, so that the sliding sleeve 10 is slidingly connected outside the circular rod 42. When the liquid floating plate 6 drives the upper slide rod 7 to move, the upper slide rod 7 pushes the sliding sleeve 10 to slide smoothly on the circular rod 42 through the corresponding connecting rod 11. At this time, the sliding sleeve 10 will push the lower slide rod 7 to move synchronously through the connecting rod 11, so that the slide rods 7 are evenly arranged in the mixing tank 1, and the slide rods 7 drive the stirring blades 8 to be evenly arranged in the liquid fertilizer.

[0039] Referring to Figures 3-6 Two guide grooves 31 are formed in the rotating shaft 3, and the guide grooves 31 are symmetrically arranged about the horizontal central axis of the sleeve ring 41. The guide grooves 31 are divided into inclined sections 301 and vertical sections 302, and the bottom end of the rotating shaft 3 is provided with a bottom blade 32.

[0040] The top of the stirring blade 8 is fixedly connected with a shaft rod 81, and the push-pull rod 9 comprises a horizontal rod 91 fixedly connected with the shaft rod 81. The middle of the horizontal rod 91 is fixedly connected with a circular shaft 92, and the circular shaft 92 is located inside the guide groove 31.

[0041] Specifically, the vertical section 302 smoothly transitions to the inclined section 301, which limits the position of the circular shaft 92. When the liquid level changes, the liquid floating plate 6 moves to drive the slide rod 7 to move up and down. When the slide rod 7 moves, it will pull the horizontal rod 91 to move synchronously through the stirring blade 8 and the shaft rod 81. The connecting rod 11 pushes the sliding sleeve 10 to slide on the circular rod 42. At the same time, the circular shaft 92 will slide in the guide groove 31. Due to the guidance of the inclined section 301 of the guide groove 31, the circular shaft 92 will produce lateral displacement during sliding, and then push one end of the shaft rod 81 through the horizontal rod 91, so as to realize the automatic adjustment of the angle of the stirring blade 8. When the liquid level stabilizes at a certain height, the stirring blade 8 maintains a fixed angle at this time, ensuring stable stirring effect and improving mixing efficiency and uniformity.

[0042] Referring to Figures 2-7 A sleeve 101 is arranged at the top of the mixing tank 1, and a plurality of guide rods 102 are fixedly connected to the sleeve 101. An electric push rod 12 is arranged at the top end of the mixing tank 1, and the electric push rod 12 is used to fix the inner tube 5. The inner tube 5 is not attached to the sleeve 101, and the inner tube 5 is slidingly connected outside the guide rods 102. The inner tube 5 is attached to the guide rods 102, and an annular groove 51 is formed in the outer wall of the inner tube 5. The guide rods 102 guide the inner tube 5. When the electric push rod 12 is started to push the inner tube 5, the inner tube 5 will be pressed and tightly attached to the guide rods 102, so as to fix the inner tube 5.

[0043] Referring to Figures 2-6The liquid floating plate 6 includes a hollow floating plate 61 located at the bottom end of the inner tube 5, and a solid sleeve 62 and a connecting ring 63 fixedly connected to the top of the hollow floating plate 61, the solid sleeve 62 is located inside the inner tube 5, the top of the connecting ring 63 is located inside the annular groove 51, and gaps exist between the solid sleeve 62, the connecting ring 63 and the inner tube 5.

[0044] Specifically, the outer surface of the inner tube 5 is a metal structure, and the inside is plastic. The liquid floating plate 6 is integrally formed in a split combination structure, and is composed of the hollow floating plate 61, the solid sleeve 62 and the connecting ring 63. The hollow structure of the hollow floating plate 61 inside effectively increases the liquid discharge volume, generates sufficient buoyancy to support the entire liquid floating plate 6 to float with the liquid surface, the solid sleeve 62 is in the form of a cylinder and is inserted into the inner tube 5 in a gap fit manner, and there is a gap between the two without contact. The gap can ensure that the solid sleeve 62 rotates freely in the inner tube 5, and the connecting ring 63 is located outside the solid sleeve 62, the outer diameter of the connecting ring 63 is slightly smaller than the inner diameter of the annular groove 51, so that the inner tube 5 limits the up-down position of the entire liquid floating plate 6. When the inner tube 5 is fixed, the entire liquid floating plate 6 can only rotate and cannot move up and down. When the liquid level in the mixing tank 1 rises, the hollow floating plate 61 is affected by the liquid buoyancy, driving the solid sleeve 62 and the connecting ring 63 to slide upward along the inner tube 5 synchronously, and the inner tube 5 and the entire liquid floating plate 6 move downward under their own gravity when the liquid level falls.

[0045] Referring to Figures 1-8 When the circular shaft 92 is located at the end point of the upper inclined section 301, it is a high liquid level, the angle between the stirring blade 8 and the central axis of the slide rod 7 is forty-five degrees, which can push the fluid to flow upward from the bottom and then fall from all around, forming a complete circulation path, thereby promoting the fluid to circulate up and down and lifting the stagnant fluid at the bottom to the upper layer to avoid stratification. When the circular shaft 92 is located at the end point of the upper vertical section 302, it is a lower liquid level, the angle between the stirring blade 8 and the central axis of the slide rod 7 is thirty degrees, which reduces the axial flow and avoids excessive fluctuation of the liquid surface, while effectively reducing the energy consumption of rotation.

[0046] Referring to Figures 1-9 The two sides of the hollow floating plate 61 are provided with extension plates 611, the extension plates 611 are fixedly connected with connecting sleeves 601, the connecting sleeves 601 are hinged to the upper slide rod 7, and the hollow floating plate 61 is provided with a through hole 602.

[0047] Specifically, the connecting sleeve 601 is made of high-strength stainless steel and inlaid with a wear-resistant copper sleeve inside, the inner diameter of the connecting sleeve 601 is matched with the hinge shaft at the end of the upper slide rod 7, so that the slide rod 7 can rotate flexibly in the vertical plane, and the wear of the hinge part is reduced through the antifriction property of the copper sleeve, thereby ensuring smooth transmission between the liquid floating plate 6 and the slide rod 7. The edge of the through hole 602 is treated by rounding, so that the liquid fertilizer can pass through the through hole 602.

[0048] Referring toFigures 1-9 The number of the connecting rods 11 is twice that of the sliding sleeves 10, and the connecting rods 11 are fixedly connected with the side blades 13, and the sliding sleeves 10 are not in contact with the vertical plates 43, so that the collision damage is avoided.

[0049] The working principle of the present application is as follows: when the liquid fertilizer raw materials enter, the hollow floating plate 61 will move up and down accordingly, so that the whole liquid floating plate 6 floats on the surface of the liquid fertilizer, and when the hollow floating plate 61 moves, the extension plates 611 on both sides of the hollow floating plate 61 drive the upper sliding rods 7 to move synchronously through the connecting sleeve 601, and because the two sliding rods 7 are connected with the sliding sleeve 10 through the connecting rods 11, the movement of the upper sliding rods 7 will push the sliding sleeve 10 to slide on the round rod 42 through the connecting rods 11, thereby driving the lower sliding rods 7 to move synchronously, so that the two sliding rods 7 are always evenly distributed in the liquid, avoiding the occurrence of stirring blind area, and at the same time, in the process of the sliding rods 7 moving up and down with the whole liquid floating plate 6, the movement of the sliding rods 7 will pull the cross rod 91 through the stirring blades 8 and the shaft rod 81, and because the round shaft 92 in the middle of the cross rod 91 is placed in the guide groove 31 of the rotating shaft 3, the round shaft 92 slides in the guide groove 31, so that the round shaft 92 generates lateral displacement when sliding, and pushes the shaft rod 81, so that the angle adjustment of the stirring blades 8 is synchronized, realizing the automatic adjustment of the angle of the stirring blades 8, and after stopping feeding, because the position of the electric push rod 12 is fixed, the lifting of the liquid floating plate 6 is stable, and then the motor 2 outputs power to the rotating shaft 3, driving the whole stirring system to operate.

[0050] Embodiment two, referring to Figures 1-9 As a second embodiment of the present application, a mixing method based on fertilizer production is adopted, and a mixing device based on fertilizer production is used, which comprises the following steps:

[0051] Step one: according to the requirements, the raw materials are proportioned and weighed, and at the same time, the raw materials are fed into the mixing tank 1 in order.

[0052] Step two: after the raw materials are poured into the mixing tank 1, the liquid floating plate 6 is adjusted with the liquid level, and the raw materials are stirred uniformly through the stirring blades 8.

[0053] Step three: after the mixed liquid fertilizer is transported through the pipeline, the filling treatment is carried out.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
