一种用于碾米机的凉米装置

Abstract

本实用新型涉及一种用于碾米机的凉米装置，包括凉米仓、通风仓、吸风管和调风阀；凉米仓的顶部开设有进料口和进气口；凉米仓的底部开设有与下一级设备密封连接的出料口；通风仓设置在凉米仓的内部，通风仓的底部设置有与凉米仓的下部连通的通风口，通风仓的顶部连通设置吸风管；吸风管用于与风道管网连通，以对通风仓和凉米仓形成负压抽吸，形成从进料口进入、从上向下经过凉米仓、最后经通风仓和吸风管输出至风道管网的冷却风路；吸风管上设置有调风阀，以对冷却风路的风量进行调节。可根据不同凉米装置的冷却需求，独立调节每个凉米仓的冷却风量，从而在统一风道系统供风的前提下，实现各个凉米装置的风量独立控制。

Claims

1. A rice cooling device for a rice mill, characterized by: This includes a rice cooling bin, a ventilation bin, an air intake pipe, and an air regulating valve; The top of the rice cooling bin is equipped with a feed inlet and an air inlet; The bottom of the rice cooling silo has a discharge port that is sealed and connected to the next stage of equipment; The ventilation chamber is located inside the rice cooling chamber. The bottom of the ventilation chamber is provided with a ventilation opening that communicates with the lower part of the rice cooling chamber, and the top of the ventilation chamber is provided with an air suction pipe. The suction pipe is used to connect with the air duct network to create negative pressure suction in the ventilation chamber and the rice cooling chamber, forming a cooling air path that enters from the feed inlet, passes through the rice cooling chamber from top to bottom, and is finally output to the air duct network through the ventilation chamber and the suction pipe. The air intake pipe is equipped with an air regulating valve to adjust the airflow of the cooling air path.

2. A rice cooling device for a rice mill as claimed in claim 1 wherein: The rice cooling silo is equipped with a temperature and humidity sensor at its discharge port, and both the temperature and humidity sensor and the air regulating valve are connected to the controller.

3. A rice cooling device for a rice mill as claimed in claim 1 or 2, wherein: The side wall of the rice storage bin has multiple air inlets, and each air inlet is equipped with an air inlet door.

4. A rice cooling device for a rice mill as claimed in claim 3 wherein: Both sides of the air supply door are horizontally fixedly connected to telescopic rods, and the other end of the telescopic rods is fixedly connected to the inner wall of the rice cooling bin.

5. A rice cooling device for a rice mill as claimed in claim 1 or 2, wherein: The rice cooling bin is equipped with multiple fabric strips, with multiple layers of fabric spaced vertically. The fabric strips in each layer are arranged horizontally and vertically, and the fabric strips of two adjacent layers are arranged alternately to disperse the material flow.

6. A rice cooling device for a rice mill as claimed in claim 1 or 2, wherein: The cooling rice bin is equipped with a flow plate, which is located above the discharge port and is inclined downwards towards the ventilation opening.

7. A rice cooling device for a rice mill as claimed in claim 6 wherein: The flow plate is rotatably installed in the rice cooling bin via an angle adjustment mechanism.

8. A rice cooling device for a rice mill as claimed in claim 7 wherein: The angle adjustment mechanism includes a rotating shaft, a rotating handle, a limiting ring, and a limiting pin; the rotating shaft is rotatably installed in the rice cooling bin, the rotating shaft is fixedly connected to the flow plate, and one end of the rotating shaft passes through the rice cooling bin and is fixedly connected to the rotating handle. The limiting ring is fixed on the outer wall of the rice cooling bin and is coaxial with the rotating shaft. Multiple limiting holes are arranged circumferentially on the limiting ring. The rotating handle is detachably limited to the limiting ring through the limiting pin and the limiting holes.
