Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to a precise proportioning device for chemical material production. Background Art

[0002] Precise proportioning in the production of chemical materials is a key link to ensure product quality, improve production efficiency and reduce costs. Although the existing proportioning device can complete the proportioning of various raw materials and can proportion the input raw materials according to weight and volume, it is found in the actual feeding process that many chemical raw materials are in powder form. When the existing precise proportioning device is used for pipeline transportation, it will inevitably cause the raw materials to stick to the inner wall of the pipeline, causing the proportion of input raw materials to change, and the accurate input of chemical raw materials cannot be guaranteed. In particular, the existing automated proportioning device uses a large number of transfer and transmission structures to increase the contact area between chemical raw materials and objects, so that more raw materials are attached to the transfer and transmission structure and the inner wall of the pipeline, resulting in a large error between the output and input raw materials, and the proportioning error becomes larger, which is not conducive to accurate proportioning. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a precise proportioning device for producing chemical materials.

[0007] As a preferred technical solution of the utility model, the filter layer is coaxially arranged with the material collecting tube, and the filter layer includes a filter sleeve, an air filter cotton sleeve, and a moisture-proof sleeve.

[0023] Embodiment 1:

[0024] See also Figure 1-6 Structural schematic diagram, the utility model provides the following technical solutions:

[0025] Specifically, it refers to a precise proportioning device for chemical material production, including a batching box 1, a material collecting cylinder 3 and a plurality of storage boxes 2 installed on the top of the batching box 1, a cylinder cover 4 connected to the batching box 1 is fixed on the top of the material collecting cylinder 3 by bolts, a discharge pipe 5 with a valve and connected to the inner cavity of the material collecting cylinder 3 is installed at the bottom of the material collecting cylinder 3, an air outlet hole 6 is opened on the outer circular surface of the material collecting cylinder 3, and a filter layer 7 is installed in the material collecting cylinder 3; an inert gas input pipe 8 runs through the batching box 1, and the inert gas input pipe 8 is connected to the inner cavity of the batching box 1.

[0026] The batching box 1 is composed of a top cylindrical tube and a bottom conical tube. The inert gas input pipe 8 is fixed along the tangent direction of the outer surface of the top cylindrical tube of the batching box 1. The inert gas input pipe 8 is connected to the inner cavity of the batching box 1. There are two inert gas input pipes 8, which accelerate the cleaning of the inner wall of the batching box 1 from both sides at the same time.

[0027] The material storage box 2 is connected to the inner cavity of the material distribution box 1 through a conduit with a flow valve installed at the bottom, and a mounting hole matching the conduit is opened on the top of the material distribution box 1.

[0028] The working principle of the precise proportioning device for chemical material production provided by the utility model is as follows:

[0029] Working principle: the powder stored in the storage box 2 enters the mixing box through the batching box 1 and the material collecting tube 3. After the input of a single or multiple powdered chemical materials is completed, the inert gas is input through the inert gas input pipe 8. The inert gas blows the powder attached to the inner wall of the batching box 1, and the inert gas flows. The inert gas is discharged from the air outlet 6 on the material collecting tube 3. The powder is intercepted by the filter layer 7 and is retained in the material collecting tube 3. After the powder is collected, the valve on the discharge pipe 5 is opened, so that the residual powder is introduced into the chemical material mixing box again, avoiding the waste of chemical materials, reducing the error of chemical material input, and improving the proportioning accuracy of the precise proportioning device.

[0030] Embodiment 2:

[0031] Based on the specific embodiment 1, the difference of this embodiment is that:

[0032] like Figure 3 , 4 As shown in Figures 6 and 7, the filter layer 7 is coaxially arranged with the material collection tube 3. The filter layer 7 includes a filter sleeve 701, an air filter cotton sleeve 702, and a moisture-proof sleeve 703. The filter sleeve 701, the air filter cotton sleeve 702, and the moisture-proof sleeve 703 are coaxially arranged from the inside to the outside in sequence, and the filter sleeve 701 is provided with dense holes in the circumferential direction. A filter screen 9 matching with the air outlet 6 is installed on the outer circumferential surface of the material collection tube 3. The filter screen 9 is used to prevent pollutants in the outside air from polluting the air filter cotton sleeve 702 and the moisture-proof sleeve 703. The moisture-proof sleeve 703 can absorb moisture in the air to prevent moisture from entering the material collection tube 3, so that the inner wall of the material collection tube 3 remains dry, which is conducive to the powder falling from the pipeline and the material collection tube 3, and improves the accuracy of the precise proportioning device.

[0033] The filter layer 7 can filter the inert gas containing the powdered chemical material, so that the powdered chemical material remains in the material collecting cylinder 3 , and the inert gas is discharged after being filtered by the filter layer 7 .

[0034] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
