Description

Technical Field

[0001] This utility model belongs to the field of liquid fertilizer degassing technology, specifically relating to a degassing device for liquid fertilizer production. Background Technology

[0002] Liquid fertilizer is a highly efficient compound fertilizer. It includes clear liquid, suspension, and paste types, and represents one of the current trends in the fertilizer industry. During the production process, liquid fertilizer typically requires mixing using agitation equipment. This mixing process introduces air bubbles, which, combined with the reactions of the raw materials, generate air bubbles. To prevent these bubbles from affecting the quality of the liquid fertilizer, they are removed during the production process.

[0003] In the prior art, deaerators are commonly used to remove air bubbles from liquid fertilizers. For example, utility model patent publication number CN221601308U discloses a deaerator for liquid fertilizer production. This device includes a supporting base plate, with symmetrical grooves on the upper side wall of the supporting base plate. A moving mechanism is provided inside both grooves. A collection box is fixedly installed at the left end of the upper side wall of the supporting base plate. A filter funnel is fixedly installed on the upper side wall of the collection box. A filter screen is fixedly installed inside the filter funnel. A pump body is fixedly installed inside the collection box, and a return pipe is fixedly installed at the upper end of the pump body.

[0004] The aforementioned device uses a rotating mechanism to drive the processing box to rotate, pouring the internal air bubbles into the air bubble container to achieve the effect of air bubble removal and improve the quality of liquid fertilizer production. However, this device can only be used after the liquid fertilizer has been stirred and mixed, and cannot be used during the liquid fertilizer stirring and mixing process, resulting in cumbersome and time-consuming liquid fertilizer production steps. Therefore, it is necessary to design a liquid fertilizer production deaerator that can simultaneously perform liquid fertilizer stirring and mixing and deaeration. Utility Model Content

[0009] As a further improvement to the technical solution, the shaft is located at the center of the top of the tank; the vibration rod is located at the edge of the tank.

[0010] As a further improvement to the technical solution, the stirring component includes a connecting rod and a first frame; one end of the connecting rod is connected to the shaft, and the other end is connected to the first frame; the slots of the first frame are vertically distributed.

[0026] Example 1:

[0027] like Figures 1 to 3As shown, a degassing device for liquid fertilizer production includes: a tank 1, a stirring assembly 2, and a degassing assembly 3; a liquid outlet pipe 11 is provided at the bottom of the tank 1; a valve 12 is provided on the liquid outlet pipe 11 to control its opening and closing; a feed inlet is provided at the top of the tank 1, and a cover is fitted to the feed inlet to cover it; optionally, a vent pipe is also provided at the top of the tank 1, which is connected to the tank 1 to discharge the gas inside the tank 1; the stirring assembly 2 is installed on the tank 1 to agitate the liquid inside the tank 1. The stirring and degassing assembly 3 includes an ultrasonic generator (not shown), a transducer 31, and a vibrating rod 32. The transducer 31 is disposed on the top surface of the tank body 1. The transducer 31 penetrates the pipe body 1 and extends into the interior of the tank body 1. One end of the vibrating rod 32 is connected to the transducer 31. The vibrating rod 32 is located inside the tank body 1. The ultrasonic generator is disposed outside the tank body 1 and is electrically connected to the transducer 31. The transducer 31 converts the electrical energy generated by the ultrasonic generator into mechanical energy, causing the vibrating rod 32 to generate ultrasonic vibrations. It should also be noted that the connection between the transducer and the ultrasonic generator is a conventional connection. The specific models of the transducer and the ultrasonic generator are not improvements of this application and will not be described in detail here.

[0028] like Figures 1 to 3 As shown, preferably, the stirring assembly 2 includes a motor 21, a shaft 22, and a stirring element 23; one end of the shaft 22 is vertically rotatably mounted on the top of the tank 1, and the other end extends towards the interior of the tank 1; the motor 21 is mounted on the top of the tank 1, and its output end is mechanically connected to the shaft 22 to drive the shaft 22 to rotate; preferably, the output end of the motor 21 is directly connected to the shaft 22; the stirring element 23 is mounted on the shaft 22 and rotates with the shaft 22; the stirring element 23 is located inside the tank 1. It should also be noted that the connection between the motor 21 and the shaft 22 is a conventional connection, and the specific model of the motor is not an improvement point of this application, and will not be elaborated here.

[0029] like Figure 2 and Figure 3 As shown, the preferred shaft 22 is located at the top center of the tank 1; the vibrating rod 32 is located at the edge of the tank 1 to avoid collision between the vibrating rod 32 and the stirring component 23.

[0030] Work style:

[0031] During use, the raw materials are injected into the tank 1 through the feed inlet. Then, the motor 21 and the ultrasonic generator are started. The motor 21 drives the shaft 22 to rotate, which in turn drives the agitator 23 set on the shaft 22 to stir. The agitator 21 uses mechanical shearing force and eddy current to fully mix the components of the liquid fertilizer. At the same time, the transducer 31 converts the electrical energy of the ultrasonic generator into mechanical vibration energy. The mechanical vibration energy is transmitted to the liquid fertilizer through the vibrating rod 32. The cavitation effect of the ultrasonic vibration causes a large number of tiny bubbles to be generated in the liquid fertilizer. The bubbles vibrate violently and break under the sound pressure of the sound waves, causing the gas in the liquid fertilizer to escape. At the same time, the liquid fertilizer is stirred and degassed, which effectively simplifies the production process of liquid fertilizer and shortens the production cycle.

[0032] like Figure 3 As shown, preferably, the degassing assembly 3 further includes an amplitude transformer 33; the vibrating rod 32 is connected to the transducer 31 through the amplitude transformer 33; one end of the amplitude transformer 33 is connected to the transducer 31, and the other end is connected to the vibrating rod 32. The amplitude transformer 33 transmits the ultrasonic energy vibration of the transducer 31 to the vibrating rod 32, and amplifies the amplitude of the vibrating rod 32 through the amplitude transformer 33.

[0033] Example 2:

[0034] like Figures 3 to 5 As shown, the difference from Embodiment 1 is that: a structural form of the stirring component 23 is given; the stirring components 23 are distributed in parallel and at equal intervals along the circumferential direction of the axis of the shaft 22; the stirring component 23 is located at the end of the shaft 22 away from the motor 21; the stirring component 23 includes a connecting rod 231 and a first frame 232; one end of the connecting rod 231 is connected to the shaft 22, and the other end is connected to the first frame 232; the connecting rod 231 is horizontally arranged; the slots of the first frame 232 are vertically distributed; the first frame 232 is linked to the shaft 22 through the connecting rod 231 and rotates around the central axis of the shaft 22 with the connecting rod 232. During the rotation, the first wide body 232 cuts the liquid, forming high-speed shear, breaking the viscous resistance between the liquid fertilizers, and breaking up the raw materials and bubbles. The vertically distributed first frame 232 pushes the liquid to generate radial flow (diffusion to the outer periphery) and axial flow (circulation up and down along the vertical direction of the tank 1) when rotating, so as to promote the full mixing of liquids at different depths in the tank 1.

[0035] like Figures 3 to 5As shown, preferably, the mixing component 23 further includes a connecting plate 233 and a second frame 234; the first frame 232 is connected to the connecting rod 231 via the connecting plate 233; the plate surface of the connecting plate 233 is connected to one end of the connecting rod 231 away from the shaft 22, and its other plate surface is connected to the first frame 232 and the second frame 234; the first frame 232 and the second frame 234 are on the same horizontal plane, and the size of the second frame 234 is smaller than the size of the first frame 232. When the shaft 22 rotates, the liquid fertilizer passes through the first frame 232 and the second frame 234 in sequence; the second frame 234 further disperses the bubbles and raw materials after they have been dispersed by the first frame 232, refines the remaining tiny bubbles and raw materials, and at the same time enhances the turbulence in the area of ​​the shaft 22, supplements the mixing intensity in the central area, and eliminates the mixing blind zone.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
