Description

Technical Field

[0001] The utility model relates to a novel Ω - tube trough - type vibrating conveying device. Background Art

[0002] With the breakthrough of energy storage technology in the lithium - battery industry, new energy vehicle enterprises at home and abroad have risen rapidly. There is a huge gap in the demand for ternary cathode materials. As the key raw material for ternary materials, the performance of the precursor directly affects the quality of the product. The demand for precursor production capacity has driven a series of precursor equipment manufacturers, such as new rotary kilns, ultrasonic vibrating sieves, screw conveyors, vibrating conveyors, etc.

[0003] For the conveying process solutions of mainstream precursor equipment manufacturers, they are mainly divided into screw conveying and vibrating conveying. Although screw conveying has the characteristics of long - distance conveying and large conveying capacity, it has poor conveying effect for materials with high viscosity, high humidity, and easy to agglomerate. Secondly, the noise, construction cost, and maintenance cost of screw conveying are also relatively high; although vibrating conveying has gradually been recognized by the industry due to its advantages such as high conveying efficiency, stability, and low cost, further innovation is still needed for the problems of easy wear and easy adhesion of materials to the equipment.

[0004] Combined with the problems of high - viscosity, high - humidity, easy - to - agglomerate materials and dust encountered in the actual production of precursor materials, starting from the working principle of the equipment itself and the movement trajectory of the materials, this invention designs a novel Ω - tube embedded trough - type vibrating conveying device by introducing ideas such as breaking plate - formation and dehumidification. Summary of the Invention

[0005] The problem to be solved by the utility model is: to provide a novel Ω - tube embedded trough - type vibrating conveying device, which can break the plate - formation and sticking phenomena during the transportation of high - humidity materials, has an automatic cleaning function, and improves the production efficiency of the equipment.

[0006] The technical solution adopted by the utility model to solve the above problems is: a novel Ω - tube trough - type vibrating conveying device, which includes a trough body and an exciter connected to the trough body. The trough body includes a feed inlet, a discharge outlet, and a conveying surface. A storage bin is arranged above the feed inlet, and the storage bin conveys materials to the conveying surface through the feed inlet. A collection box for collecting materials is arranged below the discharge outlet. The exciter provides an exciting force to the trough body, and the exciting force is conducted to the conveying surface through the trough body, so that the materials on the conveying surface bounce upward and move towards the discharge outlet and finally fall into the collection box. An internal air - jet structure is also arranged on the trough body, and the internal air - jet structure is used to eject gas to cover the conveying surface and blow off the materials adhered to the conveying surface.

[0007] Compared with the prior art, materials are conveyed to the conveying surface through a silo, and an exciter provides an exciting force to the trough body. The exciting force is conducted to the conveying surface through the trough body, causing the materials located on the conveying surface to bounce upward and move towards the discharge port at the same time. The sticky agglomerated structure of the materials is broken up, and finally falls into the collection box, forming a complete closed-loop material handling process. An internal air jet structure is provided on the trough body, and the internal air jet structure sprays gas to cover the conveying surface, blowing off the materials sticking to the conveying surface from the conveying device, effectively solving the problems of sticking and caking during transportation, and blowing and cleaning the conveying surface reduces the cleaning time and improves production efficiency.

[0008] Preferably, the internal air jet structure includes an Ω-tube body fixed on the conveying surface along the material conveying direction and a gas source. The inside of the Ω-tube body is hollow to form a cavity communicated with the gas source. A plurality of jet pipes are arranged at intervals along the material conveying direction on its outer wall. The air outlet of the jet pipe faces the conveying surface, and the high-pressure gas provided by the gas source passes through the cavity and is discharged from the air outlet of the jet pipe.

[0009] Preferably, the Ω-tube body is generally circular in shape, and its outer surface includes an upper semi-circular arc surface and a lower semi-circular arc surface separated up and down with the maximum outer shape as the boundary. The air outlet of the jet pipe is arranged on the lower semi-circular arc surface.

[0010] Preferably, an installation surface is provided at the lower end of the lower semi-circular arc surface, and the installation surface is welded and fixed to the conveying surface through a connecting piece.

[0011] Preferably, both the trough body and the connecting piece are made of carbon steel substrate lined with polytetrafluoroethylene material. This material has excellent chemical stability, is durable, and has a very low friction coefficient, which is beneficial for conveying.

[0012] Preferably, the cross-section of the cavity is an ellipse with the long axis perpendicular to the installation surface. The elliptical cavity can generate a greater wind speed compared to a circular cavity with the same cross-sectional area. Description of the Drawings

[0020] The embodiments of the present invention will be further described below with reference to the drawings.

[0021] Please refer to Figures 1 to 3, this new type of Ω-tube trough type vibrating conveyor device includes a trough body 1 and an exciter 2 connected to the trough body 1.

[0022] The trough body 1 is provided with a feed inlet 1.1, a discharge outlet 1.2, and a conveying surface 1.3. A storage bin 3 is arranged above the feed inlet 1.1, and materials are conveyed to the conveying surface 1.3 through the feed inlet 1.1, while a collection box 4 for collecting materials is arranged below the discharge outlet 1.2.

[0023] The exciter 2 provides an exciting force to the trough body 1, and the exciting force is conducted to the conveying surface 1.3 through the trough body 1, causing the materials on the conveying surface 1.3 to bounce upward and move towards the discharge outlet 1.2, and finally fall into the collection box 4.

[0024] In order to prevent materials from adhering to the conveying surface 1.3, an internal air jet structure 5 is also provided on the trough body 1.

[0025] This structure includes an Ω-tube body 5.1 fixed on the conveying surface 1.3 along the material conveying direction and an air source 5.2.

[0026] The inside of the Ω-tube body 5.1 is hollow and is connected to the air source 5.2. A plurality of jet pipes 5.1.2 are arranged on its outer wall at intervals along the material conveying direction, and the air outlet of the jet pipe 5.1.2 faces the conveying surface 1.3. The high-pressure gas provided by the air source 5.2 is discharged through the cavity 5.1.1 and sprayed onto the conveying surface 1.3 to blow off the adhered materials. The Ω-tube body 5.1 is in a circular tube shape, and its outer surface is divided into an upper semi-circular arc surface 5.1.4 and a lower semi-circular arc surface 5.1.5 with the maximum outer shape as the boundary. The air outlet of the jet pipe 5.1.2 is arranged on the lower semi-circular arc surface 5.1.5. The lower end of the lower semi-circular arc surface 5.1.5 is provided with a mounting surface 5.1.3, and the mounting surface 5.1.3 is welded and fixed to the conveying surface 1.3 through a connecting piece 5.3.

[0027] Both the trough body 1 and the connecting piece 5.3 are made of carbon steel base material lined with polytetrafluoroethylene material, and the cross-section of the cavity 5.1.1 is an ellipse with the long axis perpendicular to the mounting surface 5.1.3.

[0028] The working principle is as follows:

[0029] When the vibrating conveyor is started, materials fall from the upper storage bin 3 onto the trough body 1. The trough body 1 makes a directional movement through the exciter 2. When the trough body 1 vibrates forward, the movement energy is transmitted to the materials by relying on the friction force between the materials and the conveying surface 1.3 on the trough body 1, causing the materials to accelerate; when the conveying surface 1.3 vibrates backward, due to the inertia of the materials, they will still continue to move forward, and the conveying surface 1.3 moves backward from below the materials. Due to the resistance during the movement, the materials cross the previous conveying surface 1.3 and fall back onto the subsequent conveying surface 1.3, repeating this cycle to achieve the conveying of materials.

[0030] After being transported for a period of time, due to the characteristics of the ternary precursor material containing a certain amount of moisture, the material will adhere to the bottom or form caking at the bottom after long-term vibration. Intermittently control the air blowing of the air source 5.2, and the gas regularly enters the cavity 5.1.1 and blows from the air jet pipe 5.1.2 to the conveying surface 1.3 to blow off the material sticking to the conveying surface 1.3.

[0031] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation on the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
