Description

Technical Field

[0001] This utility model relates to the field of dual-outlet screw conveyors, and more particularly to a clog-resistant modified starch dual-outlet screw conveyor. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a rotating screw to push materials to achieve the purpose of conveying. It can convey horizontally, inclined, or vertically, and has advantages such as simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and suitability for enclosed transportation. Screw conveyors are divided into two types in terms of conveying form: shafted screw conveyors and shaftless screw conveyors; and in terms of shape, they are divided into U-shaped screw conveyors and tubular screw conveyors. Shafted screw conveyors are suitable for non-sticky dry powder materials and small granular materials, while shaftless screw conveyors are suitable for conveying sticky and easily entangled materials.

[0003] The modified starch dual-outlet screw conveyor is a device specifically designed for conveying modified starch materials. Its core feature is the presence of two discharge ports, enabling the material to be transported in a separate manner. Structurally, it mainly consists of screw blades, a conveying cylinder, a drive unit, and two discharge ports. During operation, the drive unit rotates the screw blades within the conveying cylinder. The modified starch, propelled by the screw blades, moves forward along the cylinder and, upon reaching its designated position, is discharged through the two outlets. This flexibly meets different conveying needs, such as transporting the material to two different subsequent processing or storage devices.

[0004] The existing modified starch double-outlet screw conveyor often clogs the discharge port of the conveyor when transporting starch due to its unique composition and poor flowability, thus affecting its normal operation. Therefore, a clog-resistant modified starch double-outlet screw conveyor is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clog-resistant modified starch double-outlet screw conveyor, which aims to improve the problem in the prior art where starch, due to its unique composition and poor flowability, often clogs the outlet of the double-outlet screw conveyor during the transport of large quantities of starch, thus affecting its normal operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clog-resistant modified starch double-outlet screw conveyor, comprising a screw conveyor body, wherein an anti-clogging device is provided inside the screw conveyor body; the anti-clogging device includes a machine body, a base fixedly connected to the side of the machine body, a feed inlet fixedly connected inside the machine body, a discharge outlet fixedly connected to the side of the machine body away from the feed inlet, a motor fixedly connected to the side of the machine body, an electric rotating rod fixedly connected to the front of the output shaft of the motor, a spiral blade fixedly connected to the side of the electric rotating rod, a main bevel gear passing through and fixedly connected inside the electric rotating rod, a rotating rod rotatably connected inside the machine body, rotating blades fixedly connected to the side of the rotating rod, a bevel gear passing through and fixedly connected inside the rotating rod, and a feeding device provided inside the machine body.

[0007] As a further description of the above technical solution: the feeding device includes a sliding frame, the sliding frame is elastically connected to a sliding rod by a spring, and a baffle is fixedly connected to the side of the sliding rod.

[0008] As a further description of the above technical solution: the teeth of the main bevel gear and the bevel gear are matched and they mesh perpendicularly to each other.

[0009] As a further description of the above technical solution: one side of the spring is fixedly connected to the inside of the sliding frame, and the other side of the spring is fixedly connected to the side of the sliding rod.

[0010] As a further description of the above technical solution: the inside of the machine body is provided with a sliding groove, and the sliding groove of the machine body matches the discharge port.

[0011] As a further description of the above technical solution: there are four rotating blades, and the four rotating blades are respectively fixedly connected to the side of the rotating rod.

[0012] As a further description of the above technical solution: the spring is in a relaxed state in its initial state.

[0013] As a further description of the above technical solution: the screw conveyor body is equipped with two anti-clogging devices inside.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when using a modified starch double-outlet screw conveyor to transport modified starch, the motor is first turned on, and the modified starch is poured in from the feed port at the same time, so that the rotating blades on the side of the rotating rod rotate and the transported modified starch is transported to the discharge port in sections. Thus, the screw blades and rotating blades work together to rotate and transport the starch, thereby avoiding the blockage caused by excessive starch accumulation inside the double-outlet screw conveyor.

[0015] 2. In this utility model, when the electric rotary rod drives the spiral cutter to transport the modified starch, its rotating blades will rotate and drive the side baffle to slide, thereby causing the sliding rod to drive the side outlet to slide. The outlet slides up and down in small amplitudes continuously, thereby achieving the auxiliary anti-blocking device to transport and discharge a large amount of accumulated modified starch and enhance the overall anti-blocking effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a modified starch dual-outlet screw conveyor with anti-clogging features, comprising a screw conveyor body 1, with an anti-clogging device 2 installed inside the screw conveyor body 1; two anti-clogging devices 2 are installed inside the screw conveyor body 1, corresponding to the dual outlets inside the dual-outlet screw conveyor. Each anti-clogging device 2 includes a body 21, with a base 22 fixedly connected to the side of the body 21, an inlet 23 fixedly connected inside the body 21, and an outlet 24 fixedly connected to the side of the body 21 away from the inlet 23. A sliding groove is provided inside the body 21, and the sliding groove matches the outlet 24. This design allows the outlet 24 to slide slightly within the body 21 via the sliding groove. A motor 25 is fixedly connected to the side of the machine body 21. An electric rotating rod 26 is fixedly connected to the front of the output shaft of the motor 25. A spiral cutter 27 is fixedly connected to the side of the electric rotating rod 26. A main bevel gear 28 is fixedly connected through the electric rotating rod 26. A rotating rod 29 is rotatably connected inside the machine body 21. Rotating blades 210 are fixedly connected to the side of the rotating rod 29. There are four rotating blades 210, and each of the four rotating blades 210 is fixedly connected to the side of the rotating rod 29. A bevel gear 211 is fixedly connected through the rotating rod 29. The teeth of the main bevel gear 28 and the bevel gear 211 are matched and they mesh perpendicularly to each other. The design of the perpendicular meshing allows the main bevel gear 28 to drive the bevel gear 211 to rotate when it rotates. A feeding device 3 is provided inside the machine body 21.

[0020] Reference Figure 3 - Figure 5 The feeding device 3 includes a sliding frame 31, which is elastically connected to a sliding rod 33 via a spring 32. In its initial state, the spring 32 is in a relaxed state. One side of the spring 32 is fixedly connected to the inside of the sliding frame 31, and the other side of the spring 32 is fixedly connected to the side of the sliding rod 33. This design allows the sliding rod 33 to slide inside the sliding frame 31 via the spring 32. A baffle 34 is fixedly connected to the side of the sliding rod 33.

[0021] Working principle: When using a modified starch double-outlet screw conveyor to transport modified starch, the motor 25 is first turned on, and the modified starch is simultaneously poured in from the feed port 23. The motor 25 turns the electric rotor 26, which, through the spiral blades 27 fixedly connected to its side, agitates and conveys the modified starch to the discharge port 24. The rotation of the electric rotor 26 causes the main bevel gear 28 on its front to rotate, which in turn drives the bevel gear 211, which in turn drives the rotor 29 to rotate. This causes the rotating blades 210 on the side of the rotor 29 to rotate, thus segmenting the transported modified starch and conveying it to the discharge port 24. The coordinated rotation and transport by the spiral blades 27 and the rotating blades 210 prevent blockage caused by excessive starch accumulation inside the double-outlet screw conveyor.

[0022] When the electric rotary rod 26 drives the spiral cutter 27 to transport the modified starch, its rotating blade 210 will rotate and drive the side baffle 34 to slide. The sliding of the baffle 34 will cause the sliding rod 33 fixed on the side of the baffle 34 to slide to the outside of the sliding frame 31 and stretch the side spring 32. When the first rotating blade 210 loses its connection with the baffle 34, its spring 32 will pull the sliding rod 33 back to the initial position inside the sliding frame 31, so that the sliding rod 33 drives the side discharge port 24 to slide. The discharge port 24 slides up and down in small amplitudes continuously, thereby achieving the auxiliary anti-blocking device 2 to transport and discharge a large amount of accumulated modified starch and enhance the overall anti-blocking effect.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
