Patent name: A manufacturing method of gravimetric blender machine
Technical field:
The utility model belongs to the technical field of construction machinery, and is specifically a gravimetric blender machine.
Background technique:
The batching machine is a kind of auxiliary concrete machinery widely used in construction sites, roads, bridges and other projects to transport a series of raw materials such as stones, sand, and stones and transport them to the host through a belt installed by itself to set the concrete mix ratio and automatically batch A device for mixing into concrete. When used in the calcination process, in order to control and calculate petroleum coke, each production line uses a batching machine for feeding control before calcination. Because the feeding range is determined, the feeding speed can be The accuracy of the feed is high, and the material particles are not uniform. Therefore, the fluctuation range of weighing and adjustment with the original batching machine is too large, the feed is unstable, and the furnace temperature fluctuates, which affects the output of petroleum coke calcining production. , Quality and energy consumption, and the batching machine often jams and damages the belt. In order to control the furnace temperature, the operator needs to constantly adjust the gas and the air door to achieve precise control.
SUMMARY OF THE INVENTION The purpose of the present utility model is to provide a gravimetric blender machine to solve the problem that the original batching machine used in the calcination process has too large a range of weighing and adjustment fluctuations, and the feed is unstable, which causes fluctuations in the furnace temperature and affects The output, quality and energy consumption of petroleum coke calcining production and the problem of frequent jamming of the batching machine and damage to the belt, which is difficult to achieve precise control. The utility model is a gravimetric blender machine consisting of an inlet 1, a roller support 2, a belt 3, an adjusting screw 4, a tail pulley 5, a support frame 6, a shearing door 7, a weighing sensor 8, a side wall 9, an outlet 10. The main pulley 11 and the scraper 12 are composed of the support frame 6 supporting the entire device from the bottom end. The tail pulley 5 and the main pulley 11 are located on the left and right sides of the entire device. A belt 3 is installed around it, and the main pulley A scraper 12 is installed on the belt 3 below 11, and an adjusting screw 4 is fixed in the middle of the entire device, that is, at the central axis of the tail pulley 5. The roller holder 2 is also installed on the inner side of the entire device, at the tail of the upper side wall 9. A shearing door 7 is provided at the end, an entrance 1 is opened above the end, an exit 10 is opened on the front side, and a load cell 8 is installed in the middle of the whole device, that is, at the center of the belt 3. The beneficial effect of a gravimetric blender machine of the utility model simplifies the weighing structure of the original batching machine, reduces the ineffective load of the weighing system, provides a suitable range and sensitivity, can realize precise control, is convenient for maintenance and replacement of spare parts, and It can ensure the normal temperature of the furnace temperature, so that it will not affect the output, quality and energy consumption of petroleum coke calcining production.
The picture is a structural schematic diagram of a gravimetric blender machine. In the picture, the entrance 1, the roller support 2, the belt 3, the adjusting screw 4, the tail pulley 5, the support frame 6, the shear door 7, the weighing sensor 8, the side wall 9, and the outlet 10. Main pulley 11, scraper 1 specific implementation
Example 1. This utility model belongs to the technical field of construction machinery, specifically a gravimetric blender machine, consisting of inlet 1, roller support 2, belt 3, adjusting screw 4, tail pulley 5, support frame 6, shearing door 7, weighing The heavy sensor 8, the side wall 9, the outlet 10, the main pulley 11, and the scraper 12. When in use, first ensure that the weighing hopper is empty, and reset the button on the control system. When the power is turned on, weigh the ingredients The weight of the material that is about to pass through the belt 3 on the machine is detected by the weighing sensor 8 under the weighing frame to determine the weight of the material on the belt 3. The digital speed sensor installed on the tail drum or rotating equipment continuously measures the feed Speed, the pulse output of the speed sensor is proportional to the speed of the belt 3. The speed signal and the weight signal are sent to the belt 3 feeding control system to generate and display the cumulative amount. The batching controller compares the flow rate with the set flow rate and is controlled by The output signal of the inverter controls the speed regulation of the frequency converter to realize the requirement of quantitative feeding.
Claim 1. A gravimetric blender machine is composed of an inlet (1), a roller support O), a belt (3), an adjusting screw 0), a tail pulley (5), a support frame (6), and a shear door (7) , Weighing sensor (8), side wall (9), outlet (10), main pulley (11), scraper (12), characterized in that the support frame (6) supports the entire device from the bottom end, and the tail pulley (And the main pulley (11) are located on the left and right sides of the whole device. Belts (3) are installed around it, and a scraper (12) is installed on the belt (3) below the main pulley (11). The middle part of the tail pulley (5) is fixed with an adjusting screw, the roller support (2) is also installed on the inside of the entire device, and a shear door (7) is provided at the end of the upper side wall (9), An inlet (1) is opened above the tail end, an outlet (10) is opened on the front end side, and a load cell (8) is installed in the middle of the whole device, that is, at the center of the belt (3).
Patent summary This utility model belongs to the technical field of construction machinery, specifically a gravimetric blender machine. When using it, you should first ensure that the weighing hopper is empty, and reset the button on the control system.
