A feeding station screen structure

Abstract

This utility model discloses a screen structure for a feeding station, comprising one or more screen layers. Each screen layer has several sets of sawtooth blades fixed on it. The top edges of the sawtooth blades are inclined, and the sawtooth edges of the two blades in each set are arranged in a scissor-like pattern. Advantages: Through the scissor-like arrangement of the sawtooth blades on the double-layer screen structure, lumpy materials falling into the hopper are crushed while larger fibrous foreign objects are intercepted. This effectively intercepts more than 80% of large fibrous foreign objects in the material falling during the feeding process, thereby improving product quality and competitiveness.

Description

Technical Field

[0001] This utility model relates to the technical field of negative electrode material production equipment, specifically a feeding station screen structure. Background Technology

[0002] In the production of artificial graphite powder for lithium battery anodes, two types of graphite materials with different particle sizes need to be mixed before packaging, according to process requirements. Before mixing, the artificial graphite powder needs to be treated by removing iron, crushing, and screening. In the early stages of production, a lot of fibrous foreign matter will be mixed into the feeding station. The main sources are: strips of cloth, gloves and other debris mixed in with the raw materials, strips of cloth, gloves, and accessories from ton bags accidentally dropped by the feeding personnel, as well as fine fibers that are worn out after these larger fibrous foreign matter are transferred into the subsequent turning equipment. If these are not removed, they will seriously affect the quality of the anode material, causing the anode of the battery made from this material to easily have quality problems such as bulging.

[0003] Fiber foreign matter is also one of the important indicators for measuring the quality of negative electrode materials. At present, it is only controlled by strengthening management, but there are no corresponding technical measures to control fiber foreign matter. Therefore, it is still impossible to completely and effectively solve the quality problems of negative electrode materials caused by fiber foreign matter, which poses a risk of customer complaints about product quality and loss of customers for the company.

The top edge of the saw teeth is inclined, and the saw teeth edges of the two saw teeth in each set are arranged in a scissor shape.

[0006] Furthermore, the screen includes a frame and several support rods that overlap and are fixed to the frame, with several sets of saw teeth fixed at intervals on each support rod.

[0007] Furthermore, the support rods are arranged in parallel to each other, and the two serrated blades in each group are arranged in parallel to each other.

[0008] Furthermore, it includes two layers of screens, the frames of the two layers of screens are coaxial circular structures, the diameter of the upper screen is larger than the diameter of the lower screen, and several connecting rods are fixed circumferentially between the frames of the two layers of screens.

[0009] Furthermore, the support rods of the upper screen and the lower screen are arranged in parallel and staggered arrangement. Each set of saw teeth of the upper screen is vertically sleeved and fixed on the corresponding support rod, and each set of saw teeth of the lower screen is parallel and fixed on the corresponding support rod.

[0011] Furthermore, a handle is fixed to the screen.

[0012] This utility model has the following beneficial effects: through the scissor-shaped saw blades arranged in each group on the double-layer structure screen, the blocky material falling into the hopper is crushed while larger fibrous foreign objects are intercepted. It effectively intercepts more than 80% of the large fibrous foreign objects in the material falling during the feeding process, thereby improving product quality and product competitiveness.

[0013] The addition of reinforcing rods enhances the impact resistance of the saw blades, extending their service life. A handle is fixed to the support rod of the upper screen for easy removal and placement; removing the screen structure facilitates the cleaning of intercepted fibrous debris.

[0021] 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.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "front", "rear", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 5 As shown, this embodiment provides a feeding station screen structure, which includes two layers of screens 1. Each layer of screen 1 includes a frame 1.1 and several support rods 1.2 that overlap and are fixed to the frame 1.1. The frames 1.1 of the two layers of screens 1 are coaxial circular structures. The diameter of the upper screen 1 is larger than that of the lower screen 1. Several connecting rods 2 are fixed circumferentially between the frames 1.1 of the two layers of screens 1. Each connecting rod 2 forms a conical surface, which is convenient to fit the conical bottom of the material bin during use.

[0024] Each support rod 1.2 is arranged parallel to each other, and the support rods 1.2 of the upper screen 1 and the support rods 1.2 of the lower screen 1 are arranged in a parallel and staggered manner. Several sets of saw blades 1.3 are fixed at intervals on each support rod 1.2. The top edge of the saw blade 1.3 with serrations is inclined. The two saw blades 1.3 in each set are parallel to each other and their saw blade edges are arranged in a scissor shape. This can crush the blocky material falling into the hopper while intercepting larger fibrous foreign objects, preventing them from flowing into subsequent equipment and being worn into fine fibers that are more difficult to remove. The material falling from the bottom of the hopper will be further processed by iron removal, crushing and screening in sequence before being mixed.

[0025] In this design, each set of saw teeth 1.3 of the upper screen 1 is vertically sleeved and fixed on the corresponding support rod 1.2, and each set of saw teeth 1.3 of the lower screen 1 is parallel and fixed on the corresponding support rod 1.2. Through the double-layer structure screen 1, more than 80% of large fiber foreign objects in the material falling during the feeding process can be conveniently and effectively intercepted, thereby improving product quality and product competitiveness.

[0026] Several reinforcing rods 3, perpendicularly arranged to the support rods 1.2, are fixedly attached to the frame 1.1 of the upper screen 1. Each set of saw teeth 1.3 is fitted and fixed to the corresponding reinforcing rod 3. The reinforcing rods 3 help to enhance the impact resistance of the saw teeth 1.3 and extend their service life. A handle 4 is fixed to the support rods 1.2 of the upper screen 1 for easy handling. Removing the screen 1 structure makes it easy to clean the fibrous foreign objects it has intercepted.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
