Description

Technical Field

A reinforcing cover plate is fixed to one side of the sealing cover plate by hot melt adhesive.

[0010] Preferably, the interval heating assembly includes a plurality of groups of interval linkage blocks arranged between the serpentine heating tube and the vibration impurity removal heat conduction plate, and the number of each group of interval linkage blocks is set to three, and an interval linkage spring is connected to the bottom end of each interval linkage block, and the bottom end of the interval linkage spring is connected to the linkage support block fixedly connected to the serpentine heating tube, and a linkage support plate is welded at the position between two adjacent interval linkage blocks, and a linkage support bar is fixed at the position between two adjacent linkage support blocks, and the interval linkage spring is respectively welded and fixed to the interval linkage block and the linkage support block, and the interval linkage spring is made of copper.

[0011] A method for using a corn seed impurity removal device with a drying effect, the specific steps of use are as follows:

[0012] Step 1: During vibration cleaning, start the vibration motor, which drives the cleaning box to vibrate, and the cleaning box drives four T-shaped vibration brackets to vibrate, and the T-shaped vibration bracket drives the vibration ring block to achieve rotational vibration, and the vibration spring vibrates up and down, and the vibration spring acts as a limit vibration, and the entire cleaning box drives the vibration cleaning heat conduction plate to vibrate;

[0013] Step 2: During energy-saving drying, squeeze the sealing cover plate, rotate the sealing cover plate toward the ignition stove body, open the opening position of the combustion box, insert your hand into the combustion box to ignite the ignition stove body, put the corn into the gap between the inside of the corn feed hopper and the guide inclined block, and move the corn down along the gap to the upper inclined surface of the vibrating impurity removal heat conduction plate. The vibrating impurity removal heat conduction plate vibrates to separate the lighter impurities from the corn, and then start the fan to generate suction in the suction bucket. The suction bucket sucks corn impurities including shrunken corn and broken corn cobs into the suction bucket, and the corn impurities flow down along the gap. The suction bucket enters into the connecting injection pipe, and is poured into the interior of the matching combustion box through the connecting injection pipe. After the ignition stove body is ventilated and ignited, the corn impurities are collected in the combustion box for ignition and combustion. The hot air after combustion is poured into the heat-conducting connecting pipe along the combustion box, and the hot air is poured into the serpentine heating pipe along the heat-conducting connecting pipe. The serpentine heating pipe circulates the air to the interior of the serpentine heating pipe to realize the serpentine circulation heating operation. In this way, the heat is transferred to the lower surface of the vibration impurity removal heat conduction plate through the serpentine heating pipe, so that the heat conduction operation of the vibration impurity removal heat conduction plate is realized, and the impurity-removing corn is vibrated and dried;

[0014] Step 3: When a large amount of hot air is generated inside the combustion box during the sealing interval, the air pressure inside the combustion box increases, and the pressure squeezes the reinforcement cover plate, and the reinforcement cover plate drives the sealing cover plate to be squeezed, and at the same time, the sealing cover plate rotates on the first limit sleeve shaft block and the second limit sleeve shaft block to squeeze the inner wall of the combustion box, and the inner wall of the combustion box is squeezed and fitted to increase the sealing of the combustion box and achieve heat preservation of the combustion box;

[0015] Step 4. During interval drying, when the serpentine heating tube is vibrating vertically, the serpentine heating tube drives multiple linkage support blocks to pull downward, and the linkage support blocks drive the interval linkage springs to stretch downward. The interval linkage blocks provide vertical support for the interval linkage springs, and the linkage support plates provide horizontal support for the two interval linkage blocks, as well as the linkage support bars provide horizontal support for the two linkage support blocks. The serpentine heating tube and the vibration impurity removal heat transfer plate are pulled vertically, so that there is a certain floating gap between the serpentine heating tube and the vibration impurity removal heat transfer plate for heating.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention adopts a heat-conducting energy-saving mechanism to make the vibration impurity removal heat-conducting plate vibrate to separate the lighter impurities from the corn, start the fan to make the suction bucket generate suction, and pour it into the interior of the matching combustion box through the connecting injection pipe. After the ignition stove body is ventilated and ignited, the corn impurities are collected in the combustion box for ignition and combustion. The hot air is then circulated to the interior of the serpentine heating tube by the serpentine heating tube to realize serpentine circulation heating of the corn to achieve drying operation. In this way, the corn impurities are used for heating, which has the function of effectively saving power loss, being more energy-saving and environmentally friendly, and making full use of the corn impurities.

[0018] 2. The present invention uses a packaging extrusion component to increase the air pressure inside the combustion box, and then presses and reinforces the cover plate. The sealing cover plate rotates and extrude the inner wall of the combustion box on the first limit sleeve shaft block and the second limit sleeve shaft block. The sealing cover plate performs an extrusion and bonding operation on the inner wall of the combustion box, thereby increasing the sealing of the combustion box, improving the thermal insulation of the entire combustion box, avoiding rapid heat loss, and improving the conservation of thermal energy;

[0019] 3. The present invention adopts an interval heating assembly to make the serpentine heating tube vibrate and drive multiple linkage blocks to pull downward at the same time, the interval linkage spring is stretched downward, and the interval linkage block plays a role of vertical support for the interval linkage spring. The serpentine heating tube and the vibration impurity removal heat conduction plate are vertically arranged. There is a certain floating gap between the serpentine heating tube and the vibration impurity removal heat conduction plate for heating, which will not cause the heating temperature of the vibration impurity removal heat conduction plate to be too high. The temperature can reach the specified temperature range for heating operation without overheating, thereby ensuring the corn drying temperature to avoid overheating damage;

[0020] In summary, through the mutual influence of the above-mentioned multiple effects, corn impurities are used for heating, which can improve the thermal insulation of the entire combustion box, avoid rapid heat loss, and improve the conservation of thermal energy. It will not cause the heating temperature of the vibrating impurity removal heat transfer plate to be too high. The temperature can reach the specified temperature range for heating operation without overheating. In summary, the full utilization rate of corn impurities is effectively improved, and the temperature loss is reduced, thereby improving the energy saving of the overall equipment.
