Description

Technical Field

[0001] The utility model relates to the technical field of suspended liquid fertilizer processing, in particular to a stirring and mixing device for suspended liquid fertilizer processing. Background Art

[0002] Suspended liquid fertilizer is a highly concentrated liquid fertilizer. Compared with clear liquid fertilizer, its nutrient content is greatly improved. The total nutrient content can reach 35-45%, or even higher, which is similar to the nutrient content of general granular compound fertilizer. It greatly reduces the transportation cost of liquid fertilizer with the same amount of nutrients and makes it possible to transport liquid fertilizer over long distances. The emergence of suspended fertilizer has greatly promoted the development of the liquid fertilizer industry.

[0003] In the preparation process of suspended liquid fertilizer, the required raw materials need to be crushed first, and the crushed raw materials are added to water to form a solid-liquid mixture. Suspension aids and other additives are added under stirring to form a relatively stable solid-liquid mixed fluid fertilizer.

[0004] The existing stirring device for suspended liquid fertilizer processing gradually exposed its shortcomings during use, which are mainly manifested in the following aspects:

[0005] First, the preparation process of suspended liquid fertilizer is cumbersome, resulting in low production efficiency. Specifically, the crushing process and the stirring and mixing process are two independent processes. The staff first needs to crush the raw materials through the crushing equipment, and then transfer the crushed raw materials to the stirring device, mix them with water to form a solid-liquid mixture, and then add suspension aids and other additives for stirring and mixing. Therefore, the preparation process of suspended liquid fertilizer is cumbersome, resulting in low production efficiency.

[0006] Second, the period required for uniform mixing of the solid-liquid mixture and the additives is long, resulting in low mixing efficiency. Specifically, the solid-liquid mixture formed by adding the crushed raw materials to water is relatively viscous, and the additives have poor flow effect in the viscous solid-liquid mixture. In addition, the staff adds the additives to the device one by one, so it takes a long time to uniformly mix the raw materials and the additives, resulting in low mixing efficiency.

[0053] The working principle of this device is:

[0054] Before preparing the suspended liquid fertilizer, water is added to the mixing tank 2 through the water inlet pipe 5, raw materials are added to the crushing tank 16 through the feed port 15, and additives are added to the additive tank 30 through the additive adding pipe 31;

[0055] When preparing suspended liquid fertilizer, the control motor 39 drives the rotating shaft 17 to rotate, and then drives the crushing knife 18 to rotate, so as to crush the raw materials in the crushing tank 16, and at the same time, the vibration motor 40 can make the screen plate 20 vibrate, so that the crushed raw materials pass through the discharge hole 19 on the screen plate 20 into the mixing tank 2, and then mix with the water in the mixing tank 2 to form a solid-liquid mixture;

[0056] The telescopic end of the electric control telescopic cylinder 36 is extended, thereby driving the driven circular plate 32 to move upward. With the cooperation of the connecting rod 33, the lifting circular plate 37 and the driving shaft 28 slide upward, the internal air pressure of the fixed cylinder 35 is reduced, and the auxiliary agent in the auxiliary agent tank 30 flows into the fixed cylinder 35 in one direction through the liquid inlet pipe 24 and the liquid inlet one-way valve 25.

After the auxiliary agents are mixed, the telescopic end of the electric control telescopic cylinder 36 is shortened, thereby driving the driven circular plate 32 to move downward, thereby driving the lifting circular plate 37 and the driving shaft 28 to move downward. The descending circular plate 37 and the driving shaft 28 slide downward, the air pressure inside the fixed cylinder 35 increases, and the mixing aid in the fixed cylinder 35 flows into the annular pipe 9 in the mixing tank 2 in one direction through the liquid outlet pipe 21 and the liquid outlet one-way valve 22. The mixing aids in the annular pipes 9 are discharged to different positions in the mixing tank 2 through the discharge pipe 8. At the same time, the driving motor 41 drives the driving rod 7 to rotate, and then drives the stirring blade 11 to rotate, so that the solid-liquid mixture and the mixing aid in the mixing tank 2 are mixed and stirred, which greatly reduces the time required for uniform mixing of the solid-liquid mixture and the aid, and improves the mixing efficiency of the solid-liquid mixture and the aid.

[0057] The device has both crushing and stirring functions. The crushed raw materials directly enter the mixing tank 2 and mix with water to form a solid-liquid mixture. The solid-liquid mixture is stirred and mixed with a mixing aid to prepare a suspended liquid fertilizer, which simplifies the preparation process of the suspended liquid fertilizer and improves production efficiency.
