Automatic stirring and supplying device for ball press

Abstract

The invention discloses an automatic stirring and supplying device for a ball press, and belongs to an automatic loading device. The device is characterized by comprising a bin, a conveyer and a loading assembly; the bin comprises a feed opening, a bin middle shaft, a stirring motor, a turntable, a ratchet wheel, a spring fixing clamp, a travel switch, a driving gear, a pawl, an auger motor, an auger bracket, an auger, a baffle plate and a spring; the travel switch is in circuit connection with the stirring motor; the conveyer is driven by a transmission motor; the loading assembly comprises a loading rack, a motor rack, a loading motor, a driving shaft, a driven shaft, a chain wheel, a hinge, a scraper bucket, a hopper, a sensor and a power supply travel switch; and the power supply travel switch is connected with a master power supply circuit. Compared with the prior art, the device has the advantages that: stirring and feed conveying in the bin are synchronously performed, so that uniform mixing of coal dust and yellow mud is ensured, and agglomeration is prevented; manpower and cost are saved; and the material flow is good in stability and more uniform.

Description

technical field [0001] The invention relates to an automatic feeding device, in particular to an automatic device suitable for feeding a ball pressing machine. Background technique [0002] The production of existing briquettes mostly adopts stand-alone operation, and the pulverized coal that has been stirred is sent into the hopper of the briquetting machine, and the briquettes are produced by the briquetting machine. At present, the mixed ingredients of pulverized coal are mostly coal (80%), yellow mud (20%) and water. Among them, yellow mud is a bonding agent, which can make the coal keep warm longer and facilitate continuous heat release; while water Adding it makes the formed coal water-resistant and convenient for storage and transportation. [0003] At present, most of the pulverized coal transportation of the briquetting machine used by people relies on manual methods to directly pour the prepared mixed pulverized coal into the hopper for feeding, which has the foll...

Problems solved by technology

[0003] At present, most of the pulverized coal transportation of the briquetting machine used by people relies on manual methods to directly pour the prepared mixed pulverized coal into the hopper for feeding, which has the following deficiencies: ①The mixing effect of the mixed pulverized coal is not good, and the composition of the slime is not well distributed. Uneven; ②Manual feeding is time-consuming and laborious, with high labor costs; ③Manual feeding has different standards, poor uniformity, and inconsistent coal weight; ④Due to the characteristics of mixed coal powder containing mud and water, it has a certain viscosity. If it is too fast or uneven, it will easily cause the arching phenomenon of the hopper and blockage of the discharge port.

Some manufacturers use auger to transport raw materials, but due to the viscosity of coal powder, it is easy to produce mixed coal powder sticking to the auger to form agglomerates
