Description

A conveyor belt type grain drying device

technical field

The utility model relates to a grain drying device, in particular to a conveyor belt type grain drying device.

Background technique

At present, most of the equipment in the market that uses gravity to directly let grain drop randomly on the hot air pipe and exhaust pipe for drying has the disadvantages of small production capacity, low thermal efficiency, large energy consumption, and easy blockage. The use of spiral drying equipment is easy to cause problems such as blockage of the spiral drying equipment because the material is too wet and sticks to the spiral blade or the wall of the pipe.

Utility model content

Based on the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a conveyor belt type grain drying device, which has fast progress, high efficiency and is not suitable for clogging.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a conveyor belt type grain drying device, including a feed hopper, a square cylinder, and a discharge hopper. The feed hopper is installed above the square cylinder, and the discharge hopper is arranged at the lower end of the square cylinder. Parallel screens and side-by-side parallel dense mesh conveyor belts are arranged in the square cylinder, and parallel hot air pipe layers or moisture exhaust ventilation pipe layers are arranged between each layer of conveyor belt rollers. The hot air pipes and moisture exhaust ventilation pipes are circular tubes , and they all only have through holes on the upper side, one end of the hot air pipe is closed, the other end communicates with the hot air source outside the square cylinder, and the openings at both ends of the dehumidification ventilation pipe communicate with the outside of the square cylinder.

Preferably, the screen is provided with a gravity sensing probe device, which is convenient for controlling the vibration frequency and intensity of the screen.

Preferably, the outlet of the hopper is equipped with a thermometer and humidity probe device, which is convenient for controlling the rate of hot air from the hot air source and the conveying speed of the conveyor belt.

In the utility model, a hot air tube layer is set between the upper and lower conveyor belt rollers, and a moisture exhaust ventilation tube layer is set between the middle conveyor belt rollers. In this way, the hot air must pass through the entire grain transportation channel of the layer before it can reach the moisture exhaust ventilator and be discharged to avoid The hot air only dries the grain in the contact part of the conveyor belt, and each layer of hot air pipes can only blow hot air upwards, and only the upper side of the dehumidification ventilation pipe has through holes, so that the upper layer of hot air pipes and the dehumidification ventilation pipe can As well as the hot air circulation between the lower hot air pipe and the dehumidification ventilation pipe at the same time, the lower hot air pipe also avoids the waste of heat energy caused by blowing hot air downwards in this layer, and maximizes the efficiency of hot air.

The beneficial effect of the conveyor belt type grain drying device of the utility model is that the drying time of the grain is improved to the greatest extent through layers of parallel conveyor belts, and the layers of hot air pipes that can only blow hot air upwards are arranged alternately in parallel in the conveyor belts. The moisture exhaust ventilation pipe not only avoids the pipe blockage caused by the direct contact between the grain and the hot air pipe and the moisture exhaust ventilation pipe, but also greatly improves the air heat efficiency, reduces energy consumption, and increases the drying capacity several times compared with the existing technology.

The above description is only an overview of the technical solutions of the present utility model. In order to better understand the technical means of the present utility model, it can be implemented according to the contents of the description, and in order to make the above-mentioned and other purposes, features and advantages of the present utility model better It is obvious and easy to understand. The following describes in detail in combination with preferred embodiments and accompanying drawings.

As a part of this description, the principle of the utility model will be described through embodiments. Other aspects, features and advantages of the utility model will become clear at a glance through the detailed description. In the referenced drawings, the same reference numerals are used for the same or similar components in different drawings.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, a conveyor belt type grain drying device of the present invention includes a feed hopper 1, a square cylinder 2, and a discharge hopper 5. The feed hopper 1 is installed above the square cylinder 2, and the discharge hopper 5 is arranged on the square cylinder. 2 lower end, wherein, the square cylinder 2 is provided with parallel screens 9 and side-by-side parallel dense mesh conveyor belts 3, and at the same time, parallel hot air pipe layers and moisture exhaust ventilation pipe layers are alternately arranged between the conveyor belt rollers, and the hot air pipes 6 and exhaust air pipe layers Wet air pipe 7 is circular pipe, and they all only have through hole 8 on the upper side, and one end of hot air pipe 6 is closed, and the other end is communicated with the hot air source outside square cylinder 2, and the opening at both ends of dehumidifying air pipe 7 is connected with The square cylinder 2 communicates with the outside world. When grain, such as rice, enters the square drying cylinder 2 from the entrance of the feeding hopper 1, and falls on the first layer of conveyor belt after being sieved on the parallel screen 9, the upper layer of conveyor belt transfers the grain to the lower layer of conveyor belt. During the process, the hot air pipe 6 feeds hot air from the hot air source, and the hot air enters the square cylinder 2 through the through hole 8 to dry the rice in the square cylinder 2, and the moisture enters through the through hole 8 on the dehumidification ventilation pipe 7 Dehumidification ventilation pipe 7, and discharge square tube 2. Grain is delivered to discharge hopper 5 by bottom conveyer belt at last and discharges.
