Description

Dust removing equipment of grain drying machine

Technical Field

The utility model belongs to the technical field of agricultural machine, a grain drying-machine is related to, especially, relate to a grain drying-machine dust collecting equipment.

Background

With the continuous development of agricultural production, the agricultural mechanization rate is improved, and the harvested grain rice is directly dried by a drying machine in a field, so that the drying machine also enters grain cooperative society and family farms. The particle dust generated in the drying operation of the existing grain dryer is basically not concentrated and dusted, but is discharged in the natural atmosphere, thus seriously influencing the current beautiful regional cities and beautiful villages. Nowadays, the continuous improvement of the environmental protection requirements of residents and cooperative farmers has certain requirements on the whole environment for drying rice. The rice drying not only needs to consider the self effect, but also needs to consider the subsequent environmental pollution problem.

At present, the harvesting mode of drying the paddy is mainly machine harvesting, and accordingly, the contents of stone impurities and dust on the surface of the paddy are much less. In the rice circulation drying process, surface particles (collectively called as dust) can be separated from the rice and washed out at the position where the machine has gaps, and certain influence is caused on the drying environment on site and the environment around the drying site.

As 2 kinds of dust are carried on the surface of the paddy, the dust with the particle size of more than 10um and the particle size of 0.25-1000 mu m is harmful to the environment and human body. Dust with the particle size of more than 10 mu m is easy to settle and separate due to the action of gravity, and dust with the particle size of 0.25-10.00 mu m is difficult to separate and is the main object of dust removal.

At present, the domestic common dust removal methods comprise a natural sedimentation method, a spraying method, a cloth bag dust removal method and the like; wherein, the bag-type dust removal comprises pulse dust removal and manual bag-type dust removal, and is industrially used at present.

1. Natural settling (also called inertial dust removal). The natural settling method is to collide a dusty gas flow with a baffle or to change the direction of the gas flow sharply, and to separate and trap particles by the inertial force of the dust particles therein. The dust removing equipment has simple structure, small resistance and low dust removing efficiency, and is generally used for primary dust removal. At present, natural sedimentation is used in areas with low requirements on dust removal environment and low-temperature circulating dryers.

The impurity that the former grain of rice was separated from it after drying is got rid of to the miscellaneous room through the fan including big miscellaneous and dust, and big miscellaneous can the free fall after touchhing the baffle, and the dust then continues to float until touchhing the baffle that hinders the motion. In order to avoid pressure loss and influence drying effect, a multi-section baffle mode is generally adopted, the distance of the baffle is particularly important in the 1 st section, generally (1.5-3.0) eD.D. is the diameter of the air pipe of the fan, and the larger the distance is, the smaller the pressure loss is.

2. Wet dust collection (also called gravity spray). The spray method is the simplest wet dust removal method, and is to wash dust-containing gas by using water droplets to make dust particles adhered and condensed and further separated from the gas flow. The dust removing equipment has high dust removing efficiency, simple structure and safe operation; the disadvantages are that the washed dust-containing sewage and sludge need to be treated, if corrosive gaseous pollutants are purified, pipelines and equipment are easy to corrode, and are easy to freeze in cold regions, and the operation cost is high. The efficiency of the device for purifying dust particles larger than 10 mu m can be more than 70 percent. The dedusting mode wastes labor and time, and is rarely adopted in the common rice drying and dedusting.

The first natural sedimentation method is particularly large in volume and is suitable for large-scale drying plants; the second wet dust collecting spraying method is one-to-one, but the equipment is still large, which is not suitable for the dust removing requirement of small monomer drying machinery, and the prices of the two methods are more than 20 ten thousand, which can not be borne by common users.

And the use of circulating water is equivalent to saving 24 cubic water sources every day.

And the power supply control device is controlled by connecting the water level controller, the water driving pump and a power supply control button by using a 220V power supply (under the condition of assembling the safety device). When the water level is lower than the water level water-driving position, the water level switch cuts off the power supply, when the water level is higher than a certain value, the water level switch is electrified, the power supply switch and the double limit switches of the water level switch are utilized to automatically (manually) control the driving water pump to work, the driving water pump drives the water pump to normally drive water to enter the spraying pipeline for spraying, and the circulating spraying operation is carried out.

And step S2, the passing wind flows through the space in the box body and rotates 360 degrees to flow towards the direction of the air outlet.

And step S3, the air current which flows into the air outlet and also has trace particle dust absorbs moisture and falls dust again under the spraying action of the air outlet again, so that the trace particle dust is settled at the bottom of the box body again.

And step S4, sinking through the secondary spraying effect, wherein the air flow basically reaches the environmental protection emission standard of the particle dust, and the air flow meeting the standard is exhausted to the atmosphere through the exhaust pipe under the effect of the exhaust pipe with the length of 4.5 meters.

Step S5, water saving function: when the water level of the reservoir is higher than the water level switch, the power supply is powered on, the driving pump works through the water pump of the power supply control device to pump out water in the reservoir, the water is led to the water pipe through a certain pressure to spray the water in the spraying pipeline, and meanwhile, the tap water switch (which can be manual or electric) is switched off manually. According to a calculation formula that the pressure of a urban main pipe with the minimum water flow PPR water pipe phi 15mm is not lower than 0.16MP, and the pressure of the pipe network tip is not lower than 0.14 MP: the hourly flow rate is calculated as the sectional area x the flow velocity x 3600 according to the formula: the sectional area is the square of the circle radius multiplied by 3.14, and the flow speed is generally 1-3 m/s when water is taken, namely calculated according to the pipe diameter of 15 mm: hourly flow rate is the cross-sectional area x flow velocity x 3600: 0.00752 × 3.14 × 1.5 × 3600 ≈ 0.954 ≈ 1 cubic water source, if tap water is used in the whole process for 24 hours a day, the water flow amount of the water pipe needs to be 24 cubic water source under a certain pressure. And the use of circulating water is equivalent to saving 24 cubic water sources every day.

S6, detecting the exhausted airflow at 1.5 m of the exhaust pipe according to the exhaust gas detection requirement by a professional detection mechanism to detect particles, wherein the method is based on the following steps: the method for measuring the particulate matters in the exhaust gas of the fixed pollution source and detecting the gaseous pollutants by the method (GB/T16157-1996) standard has the following detection results, wherein the particulate matter emission concentration standard is 20mg/m 3: the emission concentration of the particulate matter is less than 20mg/m 3. Namely, the particle emission of the grain drying machine dust removal equipment meets the relevant emission standard through physical collision and under the action of spraying, spraying and moisture absorption.
