Description

Technical Field

[0001] The present invention relates to the technical field of chemical product production, and particularly relates to a metering device for chemical product production. Background Art

[0002] In the process of chemical product production, accurately measuring the mass or volume of raw materials, intermediates and finished products is a key link to ensure product quality, improve production efficiency and reduce energy consumption. Traditional metering methods mainly rely on manual operation, such as using simple equipment like platform scales. Among them, platform scales are prone to data fluctuations in measurement due to liquid surface bumps or liquid oscillations during canning, resulting in inaccurate measurement and low efficiency.

[0003] Early automated metering devices mostly used mechanical instruments, such as rotameters, turbine flowmeters, etc. Although the metering efficiency was improved to a certain extent, there were still problems such as insufficient accuracy and frequent maintenance. With the development of sensor technology and computer control technology, modern metering devices gradually adopt advanced equipment such as high-precision mass flowmeters, weighing modules, laser rangefinders, etc., and combine with PLC (Programmable Logic Controller) or DCS (Distributed Control System) to achieve real-time monitoring and automatic adjustment. However, these high-end devices have high costs and certain requirements for the installation environment (such as vibration, temperature, electromagnetic interference, etc.), which limit their popularization and application in small and medium-sized chemical enterprises.

[0025] Example 1: As shown in the attached drawings, a metering device for the production of chemical products includes a lid 1, and further includes a fastening assembly and a floating assembly. The fastening assembly is used to fix the lid 1, and the floating assembly is used to assist in metering the chemical raw materials being canned.

[0026] In this embodiment, specifically, the fastening assembly includes a movable clamping block 2, a first spring 3, and a rubber pad 4. The movable clamping block 2 is slidably connected to the side of the lid 1. The first spring 3 is connected between the movable clamping block 2 and the lid 1. The rubber pad 4 is adhesively connected to the inner side of the movable clamping block 2. When the lid 1 is placed on the mouth of the charging bucket, the movable clamping block 2 is pulled open, so that the movable clamping block 2 clamps the mouth of the charging bucket, thereby stabilizing the lid 1 and its upper components, and then charging is carried out. Among them, the floating assembly includes a floating rod 5, a floating block 6, a floating plate 7, a torsion spring 8, a limiting spring 81, and a limiting short rod 82. The floating rod 5 is slidably connected to the inside of the lid 1. The floating block 6 is fixedly connected to the bottom of the floating rod 5. The floating plate 7 is evenly rotatably connected to the floating block 6. The torsion spring 8 is connected between the floating plate 7 and the floating block 6. The limiting short rod 82 is slidably connected to the floating rod 5. The limiting spring 81 is connected between the limiting short rod 82 and the floating rod 5. The lid 1 is placed on the mouth of the charging bucket, and the lower end of the floating rod 5, the floating plate 7, and the floating block 6 are placed in the charging bucket. Under the action of the torsion spring 8, the floating plate 7 can easily enter and exit the charging bucket, thereby measuring the raw materials. Further, a measuring assembly is further included, and the measuring assembly is used to measure the chemical raw materials. Specifically, the measuring assembly includes a fixed frame 9, a measuring plate 10, a measuring groove 11, a measuring rod 12, a limiting rod 13, a limiting block 14, a second spring 15, and an unlocking assembly. The fixed frame 9 is fixedly connected to the top of the lid 1. The measuring plate 10 is fixedly connected to the fixed frame 9. The measuring groove 11 is opened on the measuring plate 10. The measuring rod 12 is slidably connected to the measuring plate 10. The limiting rod 13 is fixedly connected to the floating rod 5. The limiting block 14 is slidably connected to the measuring groove 11. The second spring 15 is connected between the limiting block 14 and the measuring plate. The unlocking assembly is used to drive the limiting block 14 to move and no longer limit the measuring rod 12. During measurement, the measuring rod 12 is moved according to the required amount of the barrel. The measuring rod 12 is placed in the corresponding horizontal groove of the measuring groove 11. The limiting block 14 limits the measuring rod 12. Subsequently, during barrel filling, the floating rod 5, the floating block 6, and the floating plate 7 will all rise as the liquid level rises, thereby driving the limiting rod 13 to move. When the limiting rod 13 moves to contact the measuring rod 12, it means that the required amount of the barrel is reached, and at this time, it can be stopped. Among them, the unlocking assembly includes a first connecting rod 16 and a second connecting rod 17. The first connecting rod 16 is connected to the side wall of the adjacent limiting block 14. The second connecting rod 17 is used to connect all the first connecting rods 16 on the same side.

[0027] It should be noted that the top of the floating rod 5 is conical to prevent raw materials from remaining on the top of the floating rod 5 during loading. The floating rod 5 is spline-shaped, enabling the floating rod 5 to move normally when the liquid level rises during the barrel loading of raw materials, thereby achieving the metering effect. The metering tank 11 is composed of a vertical groove and several horizontal grooves, and the capacity between each horizontal groove is 250 ml.

[0028] A trigger switch can be installed between the metering rod 12 and the limiting rod 13 to trigger an alarm or stop the barrel loading of raw materials.

The present invention is not limited to the above embodiments, and its specific structure allows for changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
