Description

Technical Field

[0001] The utility model relates to the field of modified starch production and processing equipment, in particular to a modified starch feeding tank discharge dust recovery device. Background Art

[0002] The production process for modified starch involves reconfiguring the produced starch into starch milk, which is then added to a reaction tank. Various chemical raw materials are then added to the reaction tank. After heating and stirring for a certain period of time, the finished product is produced through refining, dehydration, drying, and packaging. The drying process primarily utilizes airflow drying, where the starch is fed into a cyclone separator. After separation, it enters a vibrating screen, where the coarse starch particles are screened out to produce high-quality fine starch. Currently, the screened coarse starch is usually stored in a feed tank.

[0003] During the feeding and packaging process, the feeding tank is impacted and a large amount of dust will be generated and scattered. Currently, a negative pressure pipe is usually installed at the discharge port to suck away the dust and discharge it to the outside through the air duct in the workshop to avoid dust pollution in the workshop. Although this method controls dust pollution, the long-term direct discharge of starch dust will cause waste, which is not conducive to saving resources and controlling costs. Utility Model Content

DETAILED DESCRIPTION

[0021] Example 1, see attached Figure 1-6 A modified starch feeding tank discharge dust recovery device, the main body of the device is a cylindrical recovery tank body 11, the upper end of the recovery tank body is provided with a sealing cover 12, and a partition 13 is coaxially arranged at the upper end, a suction chamber 14 is formed between the partition and the sealing cover 12, a ventilation hole 131 is provided in the middle of the partition 13, a textile filter sleeve 15 is connected to the ventilation hole 131, and an inlet 15 is provided on the upper part of the sealing cover 12 to communicate with the suction chamber 14. The air duct 121 and the induced draft duct are connected to the induced draft fan 16. The induced draft fan 16 generates suction force in the induced draft duct 121, which then acts on the suction chamber 14 and acts on the recovery tank body 11 through the ventilation hole 131, thereby generating suction force in the suction pipe 17; a suction pipe 17 is radially provided on the upper part of the side wall of the recovery tank body 11, and a discharge pipe 18 is provided at the conical bottom of the lower part of the recovery tank body 11, and the discharge pipe is passed into the closed material box 20 through the recovery pipe 19.

[0022] A conical air guide hood 21 is coaxially arranged on the inner wall of the recovery tank body 11 below the partition 13. The outlet of the conical air guide hood 21 is directly opposite to the ventilation hole 131. The conical air guide hood 21 shell guides the starch dust into the textile filter sleeve 15 for centralized blocking filtration, which is conducive to improving the recovery efficiency.

[0023] The upper surface of the partition 13 is provided with a limiting sleeve 132 arranged concentrically with the ventilation hole 131. The size of the limiting sleeve 132 is larger than the size of the textile filter sleeve 15 in the inflated state. After the suction recovery operation is stopped, the textile filter sleeve 15 is no longer in the inflated state. Under the guiding and limiting action of the limiting sleeve 132, the dust attached to the inner surface of the fabric filter sleeve is automatically and completely separated to avoid blockage.

[0024] The side of the sealing cover 12 and the port of the recovery tank body 11 are connected by a hinge 221, and a number of buckles 222 are distributed on the outer side surface of the port of the recovery tank body 11. The buckles are fastened to the edge of the upper surface of the sealing cover 12. The buckle 222 connection structure facilitates opening the sealing cover 12 to maintain the internal textile filter sleeve 15.

[0025] When the recovery device of this embodiment is working: air is drawn into the recovery tank body 11 through the induced draft pipe 121, and the suction pipe 17 on the recovery tank body 11 generates suction force, sucking the starch dust generated during the feeding and packaging process of the feeding tank into the recovery tank body 11 and being blocked by the textile filter sleeve 15. The accumulated starch dust falls to the bottom of the recovery tank body 11 for recovery, avoiding the waste caused by direct discharge of starch dust, which is beneficial to saving resources and reducing costs.

[0026] Example 2, see attached Figure 2 、 4 This embodiment is basically the same as the first embodiment, except that: the inner port of the suction pipe 17 is hinged with a partition cover 171, the hinge point of the partition cover is located at the upper part of the suction pipe 17, the lower end of the discharge pipe 18 is provided with an oblique port, and the oblique port is hinged with a blanking baffle 181 that can cover the oblique port, and an extension plate 182 is provided at the upper edge of the blanking baffle, and an iron block 183 is provided on the upper surface of the extension plate.

[0027] When the induced draft pipe 121 draws air into the recovery tank body 11 to recover starch dust, the partition cover 171 will open outward under the action of the suction force inside the recovery tank body 11, and the starch dust will be sucked into the tank body. At the same time, the blanking baffle 181 is in a closed state under the action of the counterweight block, and the discharge pipe 18 is closed. The filtered starch dust falls to the discharge pipe 18 at the bottom of the tank. When it accumulates to a certain amount, the gravity of the starch will overcome the gravity of the counterweight block, the blanking baffle 181 opens, and the starch is discharged from the discharge pipe 18.

[0028] When the air duct 121 stops drawing air into the recovery tank 11 to recover starch dust, the partition cover 171 will not be affected by external forces and will automatically fall down by gravity, closing the suction pipe 17 to prevent dust from diffusing out of the suction pipe 17.

[0029] A folding plate is provided at the outer end of the extension plate 182, and a magnet 184 is provided on the outer side of the folding plate. An electromagnetic switch 185 corresponding to the position of the magnet 184 is provided on the outer side of the recovery tank body 11. When the blanking baffle 181 is in a closed state, the magnet 184 moves upward and approaches the electromagnetic switch 185. The electromagnetic switch 185 captures the signal of the closing of the blanking baffle 181, ensuring that the blanking baffle 181 is in a closed state for suction recovery operations, thereby avoiding insufficient suction force caused by air leakage in the tank body.
