Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer equipment, and more specifically to a drum type compound fertilizer cooler. Background Art

[0002] Compound fertilizer is a kind of fertilizer composed of multiple nutrients, usually including nitrogen, phosphorus, potassium and other elements. Compound fertilizer can provide multiple nutrients required for crop growth, help to increase crop yields and improve soil fertility. Due to its combination of multiple nutrients, compound fertilizer has been widely used in agricultural production.

[0003] The drum type compound fertilizer cooler is a kind of equipment used in the compound fertilizer production process. In the compound fertilizer production, it is usually necessary to cool the compound fertilizer particles after heat treatment in order to reduce the temperature. The drum type compound fertilizer cooler is the equipment used to complete this cooling process.

[0004] The existing drum-type compound fertilizer cooler still has the following problems: the cooling effect of the existing drum-type compound fertilizer cooler is not ideal during cooling, and a longer drum or a longer time is required to achieve a better cooling effect, which undoubtedly reduces the cooling efficiency of the compound fertilizer and increases the cooling cost;

[0005] Moreover, when compound fertilizer is cooled, it may clump due to the stickiness of the particle surface and temperature unevenness. The problem of clumping or compound fertilizer plate formation during cooling can easily lead to uneven cooling effect, thus affecting the quality of the compound fertilizer after cooling and causing great trouble to its use.

[0006] In view of this, we propose a drum type compound fertilizer cooler. Utility Model Content

[0036] In some embodiments: The working principle of the air cooler 410 is based on a refrigeration cycle. The commonly used refrigeration cycle includes four processes of evaporation, compression, condensation and expansion. Through these processes, heat can be transferred from one place to another, thereby generating cold air. The structure generally includes a compressor, a condenser, an expansion valve, an evaporator, a fan and a control system, which belongs to conventional existing technology and is convenient for better cooling of compound fertilizer.

[0037] Specifically, a guide ring 431 is provided on the outer circumferential wall of the rotating ring 430 , and a guide groove matching the guide ring 431 is provided on the inner wall of the drum 200 , so as to ensure that the cold air is not transported in a manner that is convenient for the rotation of the drum 200 .

[0038] Furthermore, a cavity is opened inside the rotating ring 430, and a blowing port 432 is opened on the side wall of the rotating ring 430, so as to more evenly cover the inside of the refrigeration cavity 230 with cold air, thereby reducing the temperature of the inner wall of the drum 200 and achieving the effect of cooling the compound fertilizer.

Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0046] Working principle: First, when cooling compound fertilizer, the compound fertilizer to be cooled can be put into the feed hopper 210 and sealed with a sealing cover plate. At this time, multiple gear motors 120 cooperate with gears 130 to drive the drum 200 to rotate. During the rotation, the air cooler 410 generates cold air and introduces it into the refrigeration cavity 230 through the air duct 420, so that the cold air can be used to more evenly cover the refrigeration cavity 230 of the drum 200, accelerate the dissipation of heat, and thus better reduce the drum temperature. At the same time, multiple connecting rods 320 cooperate with multiple material diverting plates 340 to better turn the compound fertilizer over and cool it down. Then It is then transported to the outside through the spiral feeding rod 350. During the transportation process, the compound fertilizer will be continuously and evenly fed and will have more complete contact with the inner wall of the drum, thereby achieving a better cooling effect. During the stirring and turning process of the compound fertilizer, the vibrator will cooperate with the ultrasonic generator 110 to generate ultrasonic vibrations, so that the stirred and turned compound fertilizer can be broken up to avoid agglomeration and thus affect the cooling effect. In addition, during the stirring, turning and feeding process, the scraper 1 330 and the scraper 2 360 will be driven to clean the inner wall of the drum 200 at the same time, thereby avoiding the compound fertilizer sticking to the plate and affecting the cooling efficiency.
