Description

Technical Field

[0001] The utility model belongs to the technical field of powder material conveying equipment, and more specifically, relates to a screw conveying mechanism and a screw conveying system. Background Art

[0002] In the chemical, food, agricultural and sideline products industries, conveying equipment is usually used to facilitate the transportation and transfer of powdered or granular raw materials or products. Commonly used conveying equipment includes belt conveying equipment, pipeline conveying equipment also known as pneumatic conveying, and screw conveying equipment. These three conveying equipment have their own advantages. However, for powdered materials, belt conveying equipment cannot perform good closed conveying and will cause dust to fly. Pneumatic conveying and screw conveying can achieve better sealing, so they are often used in powder material transportation.

[0003] For example, in the patent CN212126779U, a powder feeding, crushing and packaging system is disclosed. The application includes a silo, a discharger, a grinder, a pumping box and an air ring pump. The discharge port of the silo is connected to the feed port of the discharger, the discharge port of the discharger is connected to the feed port of the grinder, and the discharge port of the pumping box is connected to the feed port of the silo; the air inlet of the air ring pump is connected to the air outlet of the silo. The application adopts pneumatic conveying, which has good sealing and can ensure the working environment of the workshop. However, the application has the disadvantages of long conveying pipelines, inconvenient cleaning inside the pipelines, and difficult maintenance. For another example, in the patent CN203372400U, a comprehensive conveying and packaging machine for chemical raw materials is disclosed. The application adopts spiral conveying, which has the advantages of low manufacturing cost and low maintenance difficulty compared with pneumatic conveying.

[0004] However, the existing screw conveyor system is generally only suitable for material conveying in relatively fixed places, and cannot be adjusted according to the actual conveying height. When the conveying height or angle changes, a different conveying system needs to be replaced, which limits its application range. Utility Model Content

[0005] 1. Problems to be solved

[0006] In view of the problem that the existing screw conveying system cannot adjust the height and angle according to actual needs, thus limiting its scope of use, the utility model provides a screw conveying system.

[0031] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0032] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] The utility model is further described below in conjunction with specific embodiments.

[0034] refer to Figure 1 , Figure 2 As shown, a screw conveying system of this embodiment includes a material bin 1, a screw conveying mechanism and a storage bin 2 connected in sequence. The screw conveying mechanism is used to convey and transfer the material in the material bin 1 to the storage bin 2. The screw conveying mechanism includes a screw conveyor 3 and a support frame 4. A telescopic component 5 is provided on the support frame 4, and the telescopic end of the telescopic component 5 is connected to the screw conveyor 3.

[0035] The telescopic component 5 can drive the screw conveyor 3 to move in the vertical direction to achieve the height adjustment of the screw conveyor 3. At the same time, the screw conveyor 3 can swing along the connection point with the telescopic component 5 to adjust the inclination angle of the screw conveyor 3, so as to be suitable for the transfer operation of materials under different working conditions.

[0036] As a preferred mode, a plurality of telescopic components 5 can be provided along the axial direction of the screw conveyor 3 to ensure the stability of the screw conveyor 3 in different states. The telescopic components 5 are rotatably connected to the screw conveyor 3 near the middle part.

[0037] The material bin 1 may use a spiral belt dryer to dry the material before transportation. At the same time, in order to facilitate the control of the opening and closing state of the material bin 1 discharge port, a ball valve 7 is provided at the material bin 1 discharge port.

[0038] In addition, universal wheels are provided at the bottom of the storage bin 2 and the support frame 4, which facilitates the movement of the storage bin 2 and the screw conveying mechanism, so as to form a set of conveying system with the material bins 1 in different use areas, so as to achieve the purpose of multi-purpose, and also help to expand its application range.

[0039] Specifically in this embodiment, two telescopic parts 5 are provided, and the telescopic parts 5 are electric telescopic rods. Of course, the telescopic parts 5 can also be formed by other structures driven by oil cylinders, air cylinders or screws. In short, all mechanisms in the prior art that can realize the lifting and moving of the screw conveyor 3 are applicable, and they are not described one by one here.

[0040] Meanwhile, it should be noted that the screw conveyor 3 and the spiral belt dryer in this embodiment are both existing technologies, and the driving source of the screw conveyor 3 is a variable frequency motor to facilitate the adjustment of the conveying speed of the material.

[0041] In this embodiment, the use state of the screw conveyor 3 can be roughly divided into two states. When the telescopic ends of the two telescopic parts 5 are at the same height, the screw conveyor 3 is in a horizontal state as a whole. When the telescopic ends of the telescopic parts 5 are one high and one low, the screw conveyor 3 is in an inclined state. Of course, the inclined state of the screw conveyor 3 can be divided into two states according to the height of its feed end and discharge end. Among them, the specific state of the screw conveyor 3 can be determined according to the actual needs.

[0042] As another implementation of a screw conveying system of this embodiment, the discharge port of the material bin 1 and the feed port of the screw conveyor 3, and the discharge port of the screw conveyor 3 and the feed port of the storage bin 2 are both softly connected through a connecting component 6. This soft connection docking method not only facilitates the docking between the material ports, but also compensates for the displacement and stress caused by the vibration of the equipment or pipeline. Among them, the connecting component 6 can be any one of rubber, canvas, soft plastic or bellows.

[0043] In addition, in order to facilitate the cleaning operation of each component, the two ends of the connecting component 6 can be detachably connected to the corresponding material opening through a buckle or a clamp. The buckle or the clamp is preferably made of stainless steel.

[0044] The screw conveying system of this embodiment can adjust the height and inclination angle of the screw conveyor in both directions by setting the telescopic component 5, so that it can be applied to material transfer operations under different working conditions, which is conducive to improving its application range. At the same time, the components are detachably connected to facilitate later cleaning and maintenance operations.

[0045] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
