Description

Technical Field

[0001] The invention belongs to the technical field of dust removal for grain dryers, and in particular relates to a dust removal system for grain dryers. Background Art

[0002] When using granaries to store grain, it is necessary to dry it to reduce the moisture content in the grain to meet the storage standards. Otherwise, grain with too much moisture content is not conducive to storage and is prone to deterioration and damage, resulting in waste. However, grains will inevitably carry some impurities such as straw debris, husks, dust, sand and broken grains during harvesting, transportation, temporary storage or stacking. Hot air drying is currently the most widely used and most mature grain drying method. During the drying process, impurities in the grain will flow with the hot air until they are discharged from the dryer body and become dust gas. With the gradual expansion of the construction scale of drying centers, the amount of dust gas discharged has increased exponentially. If dust removal facilities and equipment are not constructed and installed in a standardized manner, the high-concentration dust environment will directly affect the production and life of operators and surrounding residents, and even cause safety accidents such as dust explosions. At present, many grain drying centers have failed to plan and design dust removal systems according to actual conditions during planning and construction, or the construction and installation of dust removal equipment and facilities are relatively backward, and the exhaust gas discharged from drying cannot meet local environmental protection requirements;

[0003] However, after the grains are dusted, water stains are often left in the dust removal chamber, so that after the dust removal is completed, the staff need to separately deal with the water stains in the chamber, which is quite troublesome.

[0049] like Figures 2 to 4 as well as Figure 6 As shown, further, semicircular grooves 2023 are opened between the two first stirring rods 2022 and the third stirring rod 2028, and the semicircular grooves 2023 are each provided with an annular mounting plate 2024, and circular slide grooves 2025 are respectively opened on the inner and outer side walls of the two annular mounting plates 2024, and two mutually symmetrical sliding balls 2026 are slidably installed in the inner cavity of the circular slide grooves 2025, and each sliding ball 2026 is respectively fixedly installed in the inner cavity of the semicircular groove 2023, and two mutually symmetrical positioning rods 2034 are respectively fixedly installed on the opposite side walls of the two annular mounting plates 2024, and a moving rod 2044 is fixedly connected above the upper annular mounting plate 2024.

Example

[0050] The difference between the above embodiment and this embodiment is that: Figures 1 to 3 and Figure 5 to Figure 6 as well as Figure 8As shown, a grain dryer dust removal system, two opposite side walls above the inner cavity of two rectangular slots 1025 are provided with bearings 3022, four bearings 3022 are symmetrical to each other, four bearings 3022 are provided with rotating rods 3021 between two of them, two rotating rods 3021 are respectively fixed with sealing plates 302, and two sealing plates 302 are symmetrical to each other. In this setting, it is ensured that when the guide sleeve 2043 moves vertically downward, the two cleaning plates 301 can be driven to move in opposite directions by the swing rod 3012, so that the stains that slide to the bottom of the protective shell 102 can be pushed by the cleaning plate 301, until when the cleaning plate 301 drives the stains to be squeezed onto the sealing plate 302, the sealing plate 302 can be squeezed open at this time, and the staff can collect the pushed water stains, etc., so it is convenient to deal with the stains after dust removal.

[0051] The implementation principle of a grain dryer dust removal system of this embodiment is as follows:

[0052] First, the staff puts the grains into the installation shell 101 through the feed port 1013. When the grains are placed, the staff controls the dual-axis motor 2012, the heating component, the air pump and the high-pressure pump through the controller to operate. Therefore, the air pump can blow air from the bottom of the installation shell 101, and the high-pressure pump can transport water into the water tank 103, and then the water is sprayed out through the high-pressure nozzle 1032 in the water tank 103 (all of which are prior art, and the heating component is also prior art in the inner cavity of the installation shell 101);

[0053] When the dual-axis motor 2012 is started, it can drive the rotating rod 2013 and the rotating rod 204 to rotate at the same time. When the rotating rod 2013 rotates, it can drive the fixed sleeve rod 2014 to rotate. When the fixed sleeve rod 2014 rotates, it can drive the first stirring rod 2022, the second stirring rod 2027, the third stirring rod 2028 and the fourth stirring rod 2029 to rotate. Therefore, the grains placed in the inner cavity of the installation shell 101 can be stirred by the first stirring rod 2022, the second stirring rod 2027, the third stirring rod 2028 and the fourth stirring rod 2029, so that the dust in the grains can be raised under the drying effect of the heating component.

[0054] When the rotating rod 204 rotates, it can make the guide sleeve 2043 move vertically up and down with the assistance of the guide slot 2042, the guide slider and the guide rod 2045. When the guide sleeve 2043 moves, it can drive the moving rod 2044 to move vertically up and down, because the bottom of the moving rod 2044 is fixedly installed with a circular mounting plate 2024, and the circular mounting plate 2024 and the first stirring rod 2022 are slidably connected (because the first stirring rod 2022 is provided with a semicircular notch 2023, and the inner cavity of the semicircular notch 2023 is fixedly installed with a sliding ball 2026, and the inner and outer sides of the circular mounting plate 2024 are both opened A circular slide groove 2025 is provided, and a sliding ball 2026 is slidably provided in the inner cavity of the circular slide groove 2025), thereby ensuring that the moving rod 2044 can push the circular mounting plate 2024 to move vertically up and down, and at the same time drive the first stirring rod 2022 to move vertically downward under the cooperation of the slide groove 202 and the slider 2021 in the sliding mechanism provided on the fixed sleeve rod 2014, and the fixed sleeve rod 2014 itself can be rotated with the assistance of the rotating rod 2013, so that the sliding mechanism can be rotated, thereby driving the first stirring rod 2022 to rotate, so that the first stirring rod 2022 can move vertically up and down and can rotate at this time;

[0055] When the first stirring rod 2022 moves vertically downward and is in a rotating state, the second stirring rod 2027 is fixedly connected to the fixed sleeve rod 2014, so the first stirring rod 2022 and the second stirring rod 2027 rotate simultaneously, so that when the first stirring rod 2022 moves vertically downward, the first mounting block 203 can be driven to expand outward through the first movable rod 2031;

[0056] At the same time, because the connection structure between the third stirring rod 2028 and the first stirring rod 2022 is similar, and the circular mounting plate 2024 slidably arranged on the third stirring rod 2028 and the circular mounting plate 2024 slidably arranged on the first stirring rod 2022 are connected by the positioning rod 2034, the third stirring rod 2028 can also move vertically up and down when rotating. Therefore, when the third stirring rod 2028 moves vertically downward, the second movable rod 2033 arranged between the third stirring rod 2028 and the second stirring rod 2027 will be able to drive the second mounting block 2032 to retract inwardly; wherein the working principle of the third stirring rod 2028 and the fourth stirring rod 2029 is similar to the working principle between the first stirring rod 2022 and the second stirring rod 2027. Therefore, through the mutual expansion and contraction between the first movable rod 2031 and the second movable rod 2033, etc., the grains can be stirred more evenly and fully, so that the dust can be raised faster;

[0057] When the raised dust enters the inner cavity of the protective shell 102 from the connecting pipe 105 under the blowing of the air pump, the raised dust can be reduced by the water sprayed from the high-pressure nozzle 1032 (because the raised dust can move to both sides under the guidance of the guide cover 1026 when entering the protective shell 102, thus avoiding the high-pressure nozzle 1032 from spraying water into the inner cavity of the protective shell 102, and also avoiding the raised dust from being blown out directly from the air outlet 1022), so that the dust in the gas can fall onto the cleaning plate 301 under the action of the water, and because the cleaning plate 301 is inclined, the water containing stains can slide along the inclined surface of the cleaning plate 301 to the bottom of the inner cavity of the protective shell 102;

[0058] When the guide sleeve 2043 moves vertically downward, the two cleaning plates 301 can be driven to move in opposite directions through the rocker rod 3012. Therefore, the stains that have slipped to the bottom of the protective shell 102 can be pushed through the cleaning plates 301 until the cleaning plates 301 drive the stains to be squeezed onto the sealing plates 302. At this time, the sealing plates 302 can be squeezed open, and the staff can collect the pushed-out water stains, etc., so it is convenient to deal with the stains after dust removal.
