Embodiment Construction

[0036] This embodiment is an automatic weighing device for mucus, which includes a support platform 1, an annular support 2, three sensor components 3, a mucus hopper 4, a fast discharge valve 5 and a slow discharge valve 6, and the data is processed by an industrial control computer And management, and control the fast loading valve, slow loading valve, fast unloading valve 5, and slow unloading valve to complete the weighing of each material.

[0037] Such as Figure 1 ~ Figure 3 As shown, the support platform 1 is the support carrier of this embodiment. The panel of the annular support 2 is set on the circumference of the upper end of the mucus hopper 4 with a distance of 50 mm from the mucus hopper 4 . The three poles of the annular support 2 are placed on the supporting platform 1 . Three sensor assemblies are evenly distributed on the periphery of the mucus hopper 4 . The upper ends of the three sensor assemblies are respectively fixedly connected with the ring support...

Abstract

The invention relates to a device for weighing liquid with viscosity being 4mPa.S, which comprises a supporting platform, a ring support, three sensor modules, a viscose liquid hopper, a quick release valve and a slow release valve. A panel of the ring support is sleeved on the circumference of an upper end of the viscose liquid hopper, and a clearance is formed between the panel of the ring support and the viscose liquid hopper. Three support rods of the ring support are placed on the supporting platform. The three sensor modules are uniformly distributed on the periphery of the viscose liquid hopper. Upper ends of the three sensor modules are respectively and fixedly connected with the panel of the ring support; and lower ends of the three sensor modules are respectively and fixedly connected with clamping edges of the hopper. The quick release valve and the slow release valve are respectively arranged on a flange plate of a discharge hole of the viscose liquid hopper through pipelines, and are communicated with an inner cavity of the viscose liquid hopper. According to the device, loading of different release valves is controlled through an industrial control computer, the weight of materials is controlled through a manner of weighting by adopting a reduction method, the labor cost is effectively saved, the labor intensity is reduced, the automatic degree of viscose liquid weighing is greatly improved, and the problem of harming occupational health of operating personnel is solved.

Description

technical field [0001] The invention relates to the field of solid rocket motor charge, in particular to an automatic weighing device for an energetic high-viscosity liquid material with a viscosity of 4mPa·S. Background technique [0002] For decades, in the production of domestic solid rocket motor charges, the energetic high-viscosity liquid binder, one of the main components of the propellant, has been weighed by hand, which has low work efficiency and high labor intensity; in addition, the high-viscosity liquid is extremely It is easy to pollute the working environment and is not easy to clean up, resulting in a bad working environment; most importantly, during the weighing process, the toxic gas volatilized by the adhesive seriously threatens the health of operators. Therefore, the successful development of mucus automatic scales to realize the automatic weighing of energetic high-viscosity liquid materials has always been the ideal goal of the domestic propellant indu...
