AI Technical Summary
Traditional screw conveyor elevators fail to effectively remove large particles of impurities from materials, causing these impurities to be transported along with the materials, thus affecting equipment operation.
A screen pipe is installed at the inlet of the screw conveyor. The screen pipe has an annular groove, a screen frame, and a motor-driven rotating sleeve structure. Impurities are removed through the screen and reciprocating motion.
It effectively removes impurities from the material, ensuring that the material enters the elevator purely, thereby improving the equipment's operating efficiency and the quality of the material.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral feeding elevator technology, and in particular to a spiral feeding elevator with a screening structure. Background Technology
[0002] A screw conveyor is a mechanical device for continuous material conveying and lifting. It achieves continuous material conveying and vertical lifting through the rotation of screw blades and is widely used in the field of material conveying.
[0003] Traditional screw conveyor elevators directly feed materials through the material inlet. However, the materials may contain impurities larger than the material particles. If the materials are fed directly into the screw conveyor elevator without screening, the impurities will be transported along with the materials. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spiral feeding elevator with a screening structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A screw conveyor with a screening structure includes a screw conveyor body. A screening pipe is installed at the inlet of the screw conveyor body. An annular groove is formed inside the screening pipe. A fixing rod is fixedly installed at one end of the annular groove. A screen frame is set inside the screening pipe. The edge of the screen frame is located in the annular groove. A screen is set inside the screen frame. Springs are fixedly installed on both sides of the screen frame. The other end of the springs is connected to one side of the annular groove. A rotating sleeve is set on one side of the screen frame. The rotating sleeve is rotatably sleeved on the fixing rod. An extension block is set on one side of the screen frame. A groove is formed on one side of the extension block. Passive impact blocks are set on both sides of the inner wall of the groove.
[0007] A motor is fixedly installed on one side of the outer wall of the screening tube. The motor drives a rotating shaft, one end of which is located in a groove. An active impact block is provided on the rotating shaft.
[0008] In addition, a preferred structure is that arc-shaped grooves are provided at the top and bottom of both ends of the annular groove.
[0009] In addition, a preferred structure is that connectors are provided on both sides of the screen frame, and a sliding column is provided at one end of the connector.
[0010] Furthermore, in a preferred configuration, the top and bottom ends of the sliding column are respectively slidably located within two arc-shaped grooves.
[0011] In addition, a preferred structure is that the motor is provided with a protective shell, which is installed on the outer wall of the screen tube.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this invention, the motor drives the screen to reciprocate. After the material passes through the screen, it enters the main body of the screw conveyor elevator. Impurities in the material are intercepted by the screen, thus removing impurities from the material. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-7 A screw conveyor with a screening structure includes a screw conveyor body 1, a screening pipe 2 installed at the inlet of the screw conveyor body 1, an annular groove 21 inside the screening pipe 2, a fixing rod 8 fixedly installed at one end of the annular groove 21, a screen frame 4 inside the screening pipe 2, the edge of the screen frame 4 located inside the annular groove 21, a screen 3 inside the screen frame 4, springs 7 fixedly installed on both sides of the screen frame 4, the other end of the springs 7 connected to one side of the annular groove 21, a rotating sleeve 41 on one side of the screen frame 4, the rotating sleeve 41 rotatably sleeved on the fixing rod 8, an extension block 44 on one side of the screen frame 4, a groove 441 on one side of the extension block 44, and passive impact blocks 442 on both sides of the inner wall of the groove 441.
[0024] Among them, a motor 5 is fixedly installed on one side of the outer wall of the screening tube 2, and a rotating shaft 9 is installed on the motor 5. One end of the rotating shaft 9 is located in the groove 441, and an active impact block 91 is provided on the rotating shaft 9.
[0025] Meanwhile, arc-shaped grooves 22 are provided at the top and bottom of both ends of the annular groove 21.
[0026] Furthermore, both sides of the screen frame 4 are provided with connectors 42, and one end of the connector 42 is provided with a sliding column 43.
[0027] Meanwhile, the top and bottom of the sliding column 43 slide within the two arc-shaped grooves 22 respectively, making the reciprocating movement of the screen frame 4 more stable.
[0028] Furthermore, a protective shell 6 is provided outside the motor 5. The protective shell 6 is installed on the outer wall of the screen tube 2 and is used to protect the motor 5.
[0029] In this embodiment, the motor 5 is started, and the motor 5 drives the rotating shaft 9 to rotate at a constant speed. The active impact block 91 rotates and impacts the passive impact block 442, causing the screen frame 4 to rotate around the fixed rod 8, thereby compressing the spring 7. Then, the active impact block 91 rotates and impacts another passive impact block 442, causing the screen frame 4 to rotate in the opposite direction around the fixed rod 8, thereby compressing the spring 7. The screen frame 4 reciprocates under the action of the motor 5. Then, the material is poured into the screen tube 2. The material passes through the screen 3 under the reciprocating movement of the screen 3 and enters the main body 1 of the screw conveyor elevator. Impurities in the material are intercepted on the screen 3, and impurities in the material can be removed before the material is conveyed.
[0030] In this utility model, the motor 5 drives the screen 3 to reciprocate. After the material passes through the screen 3, it enters the main body 1 of the screw conveyor. The impurities in the material are intercepted by the screen 3, thus removing the impurities from the material.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
