Description

Technical Field

[0002] Suspension liquid fertilizers are widely used in agricultural production due to their advantages such as balanced nutrition, high absorption efficiency, and convenient application. These fertilizers are composed of multiple components, including macro-elements, micro-elements, and synergists.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0029] Example 1

[0030] like Figure 1 , Figure 3 and Figure 5As shown, a device for refining and mixing suspended liquid fertilizer includes a mixing tank 1. A discharge port 2 is located at the lower end of the mixing tank 1, and the discharge port 2 includes a control valve 201. The discharge port 2 at the lower end of the mixing tank 1 can be used to discharge suspended liquid fertilizer. A tank cover 3 is located at the upper end, and the tank cover 3 includes a sealing ring 301. The sealing ring 301 is disposed within the tank cover 3, and the tank cover 3 is sealed and installed on the mixing tank 1 by the sealing ring 301. The sealing ring 301 is made of rubber. It also includes a refining device 5 and a circulating pump 6; the refining device 5 is provided with a refining tube 501 installed on the tank cover 3, and a refining nozzle 502 is provided at one end of the refining tube 501 extending into the mixing tank 1. The refining nozzle 502 has several refining holes 503, and the diameter of the refining holes 503 is selected according to the requirements. When the suspended liquid fertilizer passes through the refining holes 503, the particles in the suspended liquid fertilizer can be refined to the optimal particle size. A scraper 506 is rotatably provided on the upper end surface inside the refining nozzle 502; the refining device 5 also includes a first motor 504; the first motor 504 is provided at the upper end of the refining tube 501, and the output shaft of the first motor 504 extends through the tube of the refining tube 501 to the interior and is provided with a rotating rod 505. The lower end of the rotating rod 505 is provided with a scraper 506 that abuts against the upper end surface inside the refining nozzle 502. By setting the refining device 5, the suspended liquid fertilizer can be refined through the refining tube 501. When the suspended liquid fertilizer passes through the refining nozzle 502, it can refine larger particles in the suspended liquid fertilizer through the refining hole 503. At the same time, when larger particles are blocked in the refining hole 503, they can be sheared by the rotating scraper 506. This not only prevents the refining hole 503 from being blocked, but also enhances the refining effect of the suspended liquid fertilizer.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the refining tube 501 has an inlet pipe 507 on its side above the barrel cover 3; the inlet of the circulation pump 6 is connected to the discharge port 2, and the outlet is connected to the inlet pipe 507; the circulation pump 6 includes a feed hose 601 and a discharge hose 602, with the feed hose 601 at the inlet and the discharge hose 602 at the outlet; a branch pipe 202 is provided on the side of the discharge port 2, with the feed hose 601 connected to the branch pipe 202 and the discharge hose 602 connected to the inlet pipe 507. The circulation pump 6 can transport the suspended liquid fertilizer through the branch pipe on the side of the discharge port 2 to the refining device 5. The circulation pump 6 is a high-pressure circulation pump, which can use high pressure to drive the suspended liquid fertilizer through the refining hole 503, and shear the particles in the suspended liquid fertilizer through the refining hole 503.

[0032] like Figure 2 , Figure 4 and Figures 6-8As shown, the lid 3 is equipped with an ultrasonic vibration device 4 and a stirring device extending into the mixing tank 1. The ultrasonic vibration device 4 is an ultrasonic vibrating rod of model JM-1024; the ultrasonic vibration device 4 includes a vibrating rod 401 and an ultrasonic controller 402. The vibrating rod 401 and the ultrasonic controller 402 are the structure of this model of product. The vibrating rod 401 is inserted into the lid 3, with the ultrasonic controller 402 connected to the upper end and the lower end extending into the mixing tank 1. After multiple tests, the effective frequency for eliminating foam can be determined, and then the foam in the mixing tank 1 can be eliminated by the vibrating rod 401. When ultrasound propagates in liquid, the impact force generated by the cavitation effect can destroy the liquid film of foam, causing the foam to break, thereby achieving the defoaming effect. Secondly, the vibration of ultrasound can cause liquid molecules to move violently, increasing the friction and collision frequency between liquid molecules. This accelerates the liquid flow on the foam surface, thins the liquid film, thereby reducing the stability of the foam and promoting its breakage. The mixing device includes a main mixing shaft 8 and a secondary mixing shaft 9. The main mixing shaft 8 is rotatably mounted on the tank cover 3. The upper end of the main mixing shaft 8 extends to the upper end of the tank cover 3 and is connected to a second motor 7. A spiral blade 801 is spirally arranged on the lower end of the shaft. The main mixing shaft 8 can drive the suspended liquid fertilizer in the mixing tank 1 to be stirred up and down along the spiral blade. The second motor 7 includes a fixing ring 701. The fixing ring 701 is arranged on the side of the second motor 7, and the second motor 7 is mounted on the upper end face of the tank cover 3 through the fixing ring 701. A hexagonal plug 702 is arranged on the output shaft of the second motor 7, and a hexagonal slot 802 is arranged on the upper end of the main mixing shaft 8. The hexagonal plug 702 is inserted into the hexagonal slot 802. The secondary mixing shaft 9 is detachably mounted on the shaft of the main mixing shaft 8. The auxiliary stirring shaft 9 includes a mounting ring frame 901, on which mounting bolts 902 are provided. The mounting ring frame 901 is detachably mounted on the main stirring shaft 8 via the mounting bolts 902. Multiple stirring blades 903 are sequentially arranged along the circumference of the lower end face of the mounting ring frame 901. By setting up the auxiliary stirring shaft, the multiple stirring blades 903 can horizontally agitate the suspended liquid fertilizer. Thus, the main stirring shaft 8 and the auxiliary stirring shaft 9 work together to fully agitate the suspended liquid fertilizer. Simultaneously, after the mixing tank 1 completes its agitation, water can be added to the mixing tank 1, and then the ultrasonic vibration device 4 can be adjusted to a higher frequency to perform ultrasonic cleaning inside the mixing tank 1.

The lower end of the rotating rod 505 is provided with a scraper 506 that abuts against the upper end surface inside the refining nozzle 502.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the thinner tube body 501 has an inlet pipe 507 on its side above the barrel cover 3; the inlet of the circulating pump 6 is connected to the discharge port 2, and the outlet is connected to the inlet pipe 507; the circulating pump 6 includes a feed hose 601 and a discharge hose 602, the inlet of the circulating pump 6 is provided with a feed hose 601, and the outlet is provided with a discharge hose 602; a branch pipe port 202 is provided on the side of the discharge port 2, the feed hose 601 is connected to the branch pipe port 202, and the discharge hose 602 is connected to the inlet pipe 507.

The ultrasonic vibration device 4 includes a vibration rod 401 and an ultrasonic controller 402. The vibration rod 401 is inserted into the bucket lid 3, with the upper end connected to the ultrasonic controller 402 and the lower end extending into the mixing bucket 1.

The second motor 7 includes a retaining ring 701. The retaining ring 701 is arranged on the side of the second motor 7, and the second motor 7 is mounted on the upper end face of the bucket lid 3 through the retaining ring 701. A hexagonal plug 702 is provided on the output shaft of the second motor 7, and a hexagonal slot 802 is provided on the upper end of the main stirring shaft 8.

[0037] The working principle of this utility model is as follows: During use, the main stirring shaft 8 and the auxiliary stirring shaft 9 can thoroughly stir the suspended liquid fertilizer inside the mixing tank 1.
