Description

Technical Field

[0001] The utility model belongs to the technical field of waste material production devices, in particular to a slow-release compound fertilizer particle transmission and cooling integrated machine. Background Art

[0002] In the manufacturing process of slow-release compound fertilizer, in order to facilitate the use of slow-release compound fertilizer, the corresponding slow-release compound fertilizer is generally made into granules for fertilization during farming. The granules obtained by granulation must be dried and cooled before packaging. If the finished product is not completely cooled before packaging or the packaging temperature is too high, the finished granular fertilizer will be condensed during storage, affecting product quality.

[0003] In the prior art, the slow-release compound fertilizer after drying is usually transferred to a rotary drum cooler for air cooling, and the slow-release compound fertilizer after drying also needs to be transferred from the drying device to the rotary drum cooler, and the slow-release compound fertilizer particles after cooling need to be transferred to the packaging place for packaging, which is a cumbersome process and requires many devices. Therefore, a conveying device with a cooling effect can be used to solve the problem.

[0004] The Chinese utility model patent "A screw conveyor with cooling effect" with publication number CN217599579U discloses the following content: including a motor, a tank body, a feed port and a discharge port, the tank body is installed on the right side of the motor, the feed port is connected to the top left side of the tank body, the discharge port is connected to the bottom right side of the tank body, the outer wall of the tank body is installed with a cooling component, the cooling component includes a cooling box, a controller, a liquid box, a delivery pump, an extraction pipe and a delivery pipe, the cooling box is installed on the outer wall of the tank body, the controller is fixedly connected to the front of the cooling box, and the liquid box is fixedly connected to the back of the cooling box. When the screw conveyor with cooling effect is started, the coolant inside the liquid box is extracted through the extraction pipe by the delivery pump, and is delivered to the inside of the cooling box through the delivery pipe, thereby cooling the tank body.

[0005] However, the part of the screw conveyor in the above document that can be cooled well is the material near the inner wall of the tank body, and the material near the rotating shaft cannot be fully cooled, and the cooling efficiency is low.

[0006] Therefore, there is an urgent need for a slow-release compound fertilizer particle transmission and cooling integrated machine to solve the above technical problems. Utility Model Content

The connecting ring B and the connecting ring A are detachably connected, so the cover plate can be screwed to drive the connecting ring B to rotate, so that the screen cylinder can be removed and the screen cylinder can be cleaned.
