Description

Technical Field

[0001] The utility model relates to the field of deformed starch production equipment, in particular to a dust-free feeding device for a transfer trolley. Background Art

[0002] Modified starch is a type of starch product that has undergone physical, chemical or enzymatic treatment to change the physical or chemical properties of native starch to adapt it to specific industrial applications.

[0003] The production process of modified starch usually includes steps such as pre-gelatinization reaction, washing, dehydration, drying and packaging. Pre-gelatinization reaction is the key process, which involves mixing refined starch with chemicals and heating to the appropriate temperature to initiate the reaction. The washing step is used to remove unreacted chemicals and harmful impurities. After dehydration, the modified starch is dried in an air flow dryer and crushed and packaged as needed.

[0004] During the production process of modified starch, starch materials need to be transported to the production workshop by a transfer cart for feeding operations. Currently, the transfer cart is usually pushed directly to the bottom of the storage tank, and the valve is opened to discharge the starch material into the cart. This operation step will generate a large amount of starch dust, polluting the workshop production environment and causing waste of raw materials, which needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] Example 1, see attached Figure 1-6 A dust-free feeding device for a transfer trolley includes a starch storage tank 12 mounted on a bracket 11. The dust-free feeding device is arranged directly below the starch storage tank 12. The feeding device includes a frame consisting of legs 21 and a square frame 22. A support plate 221 connected vertically and horizontally is provided between the inner side surfaces of the square frame 22. An electric push rod 23 is vertically installed on the surface of the support plate. A lifting cover plate 24 is arranged parallel to the lower side of the square frame 22. The support plate 221 provides support for the electric push rod 23, thereby providing lifting support for the lifting cover plate. A discharge pipe 241 is provided in the middle of the lifting cover plate 24. The discharge pipe and A soft connecting pipe A 25 is provided between the outlets of the starch storage tank 12. During the process of the lifting cover 24 being lifted up and down, the soft connecting pipe A is flexibly deformed to keep the discharge pipe 241 and the starch storage tank 12 in a connected state. The telescopic rod 231 of the electric push rod 23 is vertically fixedly connected to the lifting cover 24. A platform plate 26 is provided between the lower ends of the support legs 21, and a ramp plate 261 is provided on the side edge of the platform plate. The upper port size of the transfer trolley 28 matches the size of the lifting cover 24, and a handle is provided on the upper outer surface of the transfer trolley 28. The transfer trolley enters the platform plate 26 along the ramp plate 261.

[0025] An exhaust branch pipe 291 is vertically provided on one side of the lifting cover 24, and the upper end of the exhaust branch pipe is horizontally connected to the exhaust main pipe 292. A soft connecting pipe B 293 is provided between the exhaust branch pipe 291 and the exhaust main pipe 292. The soft connecting pipe B can flexibly expand and contract with the lifting and lowering of the lifting cover 24, keeping the exhaust main pipe 292 and the lifting cover in a connected state. A soft connecting pipe C 294 is connected to the exhaust main pipe 292, and the exhaust main pipe is connected to the vacuum suction hopper.

[0026] At least three electric push rods 23 are evenly spaced between the support plates 221. These electric push rods 23 ensure the stability of the lifting cover 24 during the lifting process, enabling it to move horizontally up and down, ensuring a good seal against the upper port of the transfer cart 28. An annular sealing ring is provided on the bottom surface of the lifting cover 24. The size of this annular sealing ring is the same as the size of the upper port of the transfer cart 28. The sealing ring is also used to enhance the airtightness between the lifting cover 24 and the transfer cart 28.

[0027] When the device is in use, the operator pushes the transfer cart 28 along the ramp plate 261 into the platform plate 26, moves it to the bottom of the lifting cover plate 24, starts the electric push rod 23 to push the lifting cover plate 24 downward. During this process, the flexible connecting pipe A 25 keeps the discharge pipe 241 and the starch storage tank 12 in a connected state, and the lifting cover plate 24 is tightly covered on the upper port of the transfer cart 28. Then the discharge valve of the starch storage tank 12 is opened, and the starch material is discharged from the discharge pipe 241 into the transfer cart 28. At the same time, the dust generated in the cart is promptly extracted and recovered through the exhaust main pipe 292 and the exhaust branch pipe 291. After opening the lifting cover plate 24, there will be no material dust inside the transfer cart 28, ensuring that the workshop is in a clean production environment.

[0028] Example 2, see attached Figure 2-5 This embodiment is basically the same as the first embodiment, except that: a track groove 271 composed of long strips is provided in the middle of the platform plate 26, and four rollers are arranged in a diamond shape on the bottom surface of the transfer trolley 28. The two rollers in the middle are guide rollers 281, and the two rollers on the sides are side support rollers 282. The size of the guide rollers 281 matches the size of the track groove 271; a V-shaped guide plate 273 is provided on the surface of the ramp plate 261, and the inner port of the V-shaped guide plate 273 is docked with the port of the track groove 271.

[0029] When the transfer trolley 28 of this embodiment moves toward the platform plate 26, the V-shaped guide plates 273 on both sides provide guidance for the guide rollers 281 of the transfer trolley 28, so that it can quickly and accurately enter the track groove 271. Then, under the guidance of the track groove, the transfer trolley 28 can move forward from the middle of the platform plate 26, which is conducive to its accurate movement to the bottom of the lifting cover plate 24.

[0030] A limit baffle 272 is provided at the end of the track groove 271, and a triangular reinforcement plate is provided between the outer side surface of the limit baffle and the bottom surface of the track groove 271. The limit baffle 272 is used to provide limiting support for the guide roller 281 at the front end of the transfer trolley 28, so that it can move along the track groove 271 to directly below the lifting cover 24.
