Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw material batching, and in particular to a precise automatic batching device. Background Art

[0002] Graphite is a widely used non-metallic material with excellent electrical and thermal conductivity, lubricity, and chemical stability. Finely ground graphite powder is mixed with other additives to improve its processing properties and the performance of the final product. The mixing process requires precise control of the proportions of the various raw materials, and mixing of the various raw materials using mixing equipment to ensure uniform distribution of the various components. Traditional batching systems use screw conveyors to transport raw materials from a silo to a weighing device for weighing, followed by mixing. This batching system's screw conveyor punching and dry material scale zero-point drift negatively impact batching accuracy, leading to distorted proportions and compromising the quality of graphite products. Utility Model Content

[0003] The purpose of the present utility model is to provide a precise automatic batching device to solve the problem that the traditional batching device proposed in the above background technology uses a screw conveyor to transport the raw materials in the silo to the weighing equipment for weighing and then mixes the raw materials. In this way, the punching of the screw conveyor of the batching system and the zero point drift of the dry material scale have an adverse effect on the accuracy of the batching, resulting in a disorder of the batching ratio and affecting the quality of the graphite product.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a precise automatic batching device, comprising a horizontal mixer, wherein feed ports are provided at the left and right ends and the middle position of the upper end of the horizontal mixer, and a No. 1 batching bin, a No. 2 batching bin and a No. 3 batching bin are respectively provided on the upper surface of the horizontal mixer and in front of the three feed ports, and the lower ends of the No. 1 batching bin, the No. 2 batching bin and the No. 3 batching bin are connected to one end of a screw conveyor, and support columns are provided at the four corners of the lower ends of the No. 1 batching bin, the No. 2 batching bin and the No. 3 batching bin, and a weighing sensor is provided between the lower end of the support column and the upper surface of the horizontal mixer.

[0005] Preferably, a discharge pipe is provided at the lower end of the other end of the screw conveyor corresponding to the feed port, and the lower end of the discharge pipe extends into the interior of the feed port. The upper ends of the No. 1 feeding bin, the No. 2 feeding bin and the No. 3 feeding bin are all penetrated by a feeding port, and a feeding pipe is provided inside the feeding port. A sealing cover is provided between the interior of the feed port and the discharge pipe and between the interior of the feeding port and the feeding pipe.

[0006] Preferably, a gearbox is provided on one side of the horizontal mixer, a power output end of the gearbox is connected to the main shaft of the horizontal mixer through a coupling, and a power input end of the gearbox is connected to a mixing motor through a coupling.

[0007] Preferably, a servo motor is provided at the front end of the screw conveyor, and a power output end of the servo motor is connected to the main shaft of the screw conveyor through a coupling.

[0008] Preferably, a reinforcement pad is provided on the upper surface of the horizontal mixer at a position corresponding to the weighing sensor.

[0009] Compared with the prior art, the beneficial effects of the present invention are: instead of the traditional batching device which uses a screw conveyor to transport the raw materials in the silo to the weighing equipment for weighing, a weighing sensor is set at the lower end of the silo to detect the weight of the silo in real time, and the weight of the output raw materials is calculated by measuring the weight reduction of the silo, thereby avoiding the adverse effects of the punching of the screw conveyor of the batching system and the zero drift of the dry material scale on the batching accuracy, ensuring the batching ratio, and reducing the impact on the quality of the graphite product.
