Description

Technical Field

[0001] The utility model belongs to the technical field of compound fertilizer production, in particular to a high-tower granulation device for alginate compound fertilizer. Background Art

[0002] Alginate compound fertilizer is a fertilizer that adds alginate natural active synergist to the compound fertilizer production process. It contains a certain amount of alginic acid, which is usually extracted by advanced fermentation technology to maintain its biological activity. Compared with conventional compound fertilizers, alginate compound fertilizer has higher utilization rate, better environmental friendliness, and can reduce ammonia volatilization loss. This fertilizer has developed rapidly due to its unique properties. In the production process of seaweed compound fertilizer, it needs to be granulated through a high tower, but it still has the following disadvantages in actual use:

[0003] 1. When the high tower produces alginate compound fertilizer, the molten compound fertilizer is directly transported into it, granulated after being sprayed out, and blown into it by air to cool and solidify the sprayed molten alginate compound fertilizer. However, the temperature of the produced fertilizer particles is still relatively high and has not been completely cooled. Secondary cooling is required. The production process is relatively long during operation, which affects production efficiency.

[0004] 2. When the high tower produces alginate compound fertilizer, the fertilizer droplets need to be transported to the high tower, and the air passing through the high tower cools and solidifies. However, as the fertilizer falls through the high tower, the heat on the fertilizer evaporates quickly, causing the temperature of the high tower to rise rapidly, affecting the subsequent solidification efficiency of the fertilizer droplets. Utility Model Content

[0005] The utility model aims to provide a high-tower granulation equipment for alginate compound fertilizer. By arranging a high-tower main body, a top cover, an air outlet sleeve and a fan casing, the utility model solves the problems that when alginate compound fertilizer is produced by a high-tower, the cooling of fertilizer particles requires secondary cooling, which affects the production efficiency, and the heat release during the cooling of fertilizer droplets easily causes the temperature of the high-tower to rise, which affects the subsequent fertilizer granulation efficiency.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a high-tower granulating device for alginate compound fertilizer, comprising a high-tower main body, a top cover, an air outlet sleeve and a fan casing, wherein a fan casing is arranged on one side of the high-tower main body, a top cover is fixed on the top end of the high-tower main body, an air outlet sleeve is fixedly connected to the bottom end of the high-tower main body, spiral blades are fixed in an annular array on the inner wall of the air outlet sleeve, an inner fixed column is commonly fixed on one side of all the spiral blades close to the central axis of the air outlet sleeve, when working, after the molten alginate compound fertilizer droplets passing therethrough are cooled by the high-tower main body, the fertilizer particles are transported to the air outlet sleeve, transported to a concentration bucket by the spiral blades on the inner wall of the air outlet sleeve, and the inner fan is connected therein through the fan casing.

[0008] Furthermore, a plurality of heat dissipation fins are fixed on the outer peripheral surface of the high tower body. The heat dissipation fins are arranged horizontally, and the intervals between the heat dissipation fins are equal. The high tower body accelerates heat dissipation through the heat dissipation fins.

[0009] Furthermore, a feed pipe is fixedly passed through the center of the top cover, the bottom end of the feed pipe is fixedly connected to a nozzle, and the top end of the top cover on one side of the feed pipe is fixedly connected to an exhaust pipe. The top cover transports the molten alginate compound fertilizer particles to the nozzle through the feed pipe, and then transports them to the tower body through the nozzle.

[0010] Furthermore, the inner diameter of the air outlet sleeve is equal to the inner diameter of the tower body, the bottom end of the air outlet sleeve is fixedly connected to a discharge hopper, the inner diameter of the top of the discharge hopper is equal to the inner diameter of the air outlet sleeve, and the air outlet sleeve collects the fertilizer particles passing through the spiral blades through the discharge hopper and outputs them to the discharge port.

[0011] Furthermore, the lower portion of the outer circumferential surface of the discharge hopper is fixedly connected to an air inlet pipe in a circular array, and the bottom end of the discharge hopper is fixedly connected to a discharge port. The discharge hopper conveys high-pressure air to the discharge hopper through the air inlet pipe, and the high-pressure air is conveyed through the discharge hopper and rises to the air outlet sleeve.

[0012] Furthermore, an inner fixing frame is fixed to the inner wall of the fan housing at a side away from the tower body, an inner fan is fixed in the inner fixing frame, the fan housing fixes the inner fan through the inner fixing frame, and air is blown to the tower body through the inner fan.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that when the high tower produces alginate compound fertilizer, the cooling of fertilizer particles requires secondary cooling, which affects the production efficiency. After the fertilizer particles solidified in the high tower body fall into the air outlet sleeve, they pass through spiral blades, and the air entering therein is transported to the discharge hopper through the spiral blades. When the fertilizer particles pass through the air outlet sleeve, the flow speed is slowed down by the spiral blades and they are quickly cooled by the air, so that after the fertilizer particles are solidified, they do not need secondary cooling when they are output through the high tower, and the production efficiency is higher.

[0015] 2. The utility model solves the problem that heat release during cooling of fertilizer droplets easily causes the temperature of the tower to rise, thereby affecting the efficiency of subsequent fertilizer granulation, by arranging a high tower body and a fan casing. The internal fan is started, and air is sucked into the fan casing from the outside through the internal fan. The air is then transported to the outside of the high tower body through the internal fan in the fan casing to cool the heat on the heat dissipation fins on the outside of the high tower body, so that the air in the air outlet sleeve can cool and solidify the molten alginate compound fertilizer droplets faster when passing through the high tower body.

The bottom of the high-tower body 1 is fixedly connected to the fan casing 4. There is an air outlet sleeve 3, through which the cooling air transported from the hopper 303 through the air inlet pipe 304 is transferred to the high tower body 1. Spiral blades 301 are fixed in a circular array on the inner wall of the air outlet sleeve 3. The air entering therein is transported to the concentration bucket through the spiral blades 301. When the fertilizer particles pass through the air outlet sleeve 3, the flow speed is slowed down and they are quickly cooled by the air. An internal fixing column 302 is commonly fixed on one side of all the spiral blades 301 close to the central axis of the air outlet sleeve 3.
