Description

Technical Field

[0001] The utility model relates to the technical field of calcium oxide production, in particular to an automatic weighing and measuring bucket for coal materials. Background Art

[0002] The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are raw materials used in large quantities in building materials and industry. Limestone can be directly processed into stone and burned into quicklime, which is CaO. As an industrial raw material, it can be used to produce slaked lime, gypsum powder, cement and other industrial products. In the production of calcium oxide, it is generally necessary to mix limestone with coal blocks as fuel and pour them into the kiln together.

[0003] In order to ensure the production stability of calcium oxide, quantitative weighing is required before the limestone is fed in, which is convenient for the quantitative addition of coal and ensures the firing effect of the kiln. The general measuring bucket is generally a tipping bucket, which is usually poured out at one time after weighing, resulting in the coal being weighed once and then added manually, and a mixer is required to mix the stone and coal again. Only after the stone and coal are evenly mixed can they be put into the kiln for firing. The process is cumbersome and the processing efficiency is low. In the prior art, the stone measuring bucket can be changed to a funnel form and discharged through a stone conveyor belt. Manual addition of coal is more troublesome and not conducive to automated production. Therefore, a coal automatic weighing and measuring bucket that can cooperate with a funnel-shaped stone measuring bucket is needed. When using a conveyor belt, since the coal is wet material sprinkled with water, some smaller coal blocks will adhere to the belt body of the conveyor belt, and gradually squeeze the belt body through the extension plate after rotation, resulting in wear of the belt body or even jamming of the belt body. There is room for further improvement. Utility Model Content

Inside the upper part of the hopper support 1, a hopper body 2 is arranged. In the middle of the lower part of one end of the hopper body 2, a first support seat 5 is fixedly connected. In the middle of the lower part of the end of the hopper body 2 far from the first support seat 5, a second support seat 6 is fixedly connected. In the middle of the lower parts of both sides of the hopper body 2, side support seats 17 are fixedly connected. Pressure sensors 7 are arranged at the bottoms of the first support seat 5, the second support seat 6 and the two side support seats 17. Connecting seats are fixedly connected to the bottoms of the four pressure sensors 7. The four corners of the top of the hopper support 1 are fixedly connected to the corresponding pressure sensors 7 through the connecting seats. A plurality of pressure sensors 7 are electrically connected to a machine room controller. Above the hopper body 2, there is a coal block feeding conveyor belt. The coal block feeding conveyor belt and the driving motor 11 are both electrically connected to the machine room controller. The pressure of the hopper body 2 can be detected in real time by using the machine room controller, and then the coal material can be automatically weighed. Cooperating with the driving motor 11 connected to the machine room controller, subsequent automatic feeding can be carried out through the discharge conveyor belt 9 when the weighing threshold is reached;

[0027] Outside the top of the quadrangular pyramid bottom 3, a support hanger 8 is fixedly connected. At the bottom of the support hanger 8, a discharge conveyor belt 9 is fixedly connected. Above one end of the discharge conveyor belt 9 close to the second support seat 6, a motor support 10 is fixedly connected. At the top of the motor support 10, a driving motor 11 is fixedly connected. There is a transmission belt between the output end of the driving motor 11 and the discharge conveyor belt 9. And outside the transmission belt at the bottom of the support hanger 8, a belt protective cover 16 is fixedly connected, which can prevent broken slag from getting into the pulley;

[0028] Below the hopper body 2, there is a quadrangular pyramid bottom 3. A material dropping groove 4 is opened at the bottom of the quadrangular pyramid bottom 3, and the notch of the material dropping groove 4 is horizontally arranged. At one end of the bottom of the material dropping groove 4 close to the first support seat 5, an extension plate 14 is fixedly connected along the corresponding pyramid surface. On both sides of the bottom of the material dropping groove 4, lower side plates 15 are fixedly connected. On both sides above the discharge conveyor belt 9, conveyor belt side plates 12 are arranged. The outer sides of the two conveyor belt side plates 12 are respectively fixedly connected to the inner sides of both sides of the support hanger 8. At one end of the two conveyor belt side plates 12 close to the first support seat 5, a belt rear scraper 13 is fixedly connected.

The two lower side plates 15 are both parallelogram plates corresponding to the angle of the extension plate 14, and the two sides of the two lower side plates 15 close to the first support seat 5 are respectively fixedly connected to both sides of the extension plate 14. By arranging the belt rear scraper 13 behind the extension plate 14, coal blocks can be scraped in advance to prevent small coal blocks from rotating with the belt body and then gradually squeezing the belt body of the conveyor belt through the extension plate 14, resulting in wear of the belt body or even jamming of the belt body.

[0029] Working principle: In the utility model, by arranging a pressure sensor 7 between the hopper bracket 1 and the hopper body 2, the pressure of the hopper body 2 can be detected in real time by using the machine room controller, and then the coal material can be automatically weighed. Cooperating with the drive motor 11 connected to the machine room controller, when the weighing threshold is reached, subsequent automatic feeding can be carried out through the discharge conveyor belt 9. When the hopper body 2 discharges materials, the extension plate 14 and the lower side plate 15 arranged at the bottom of the blanking chute 4 can form a chute with a one-way opening, which is convenient for discharging materials in one direction. Since the extension plate is obliquely arranged and the coal material is wet material with sprinkled water, some smaller coal blocks will adhere to the belt body of the conveyor belt, and after rotation, gradually squeeze the belt body of the conveyor belt through the extension plate 14, resulting in wear of the belt body or even jamming of the belt body. Therefore, in the utility model, by arranging a belt rear scraper 13 behind the extension plate 14, the coal blocks can be scraped off in advance, avoiding the above problems.
