Abstract
The utility model provides a stable feeding device of air flow in fumed silica production be equipped with diverging device on the pipeline, diverging device includes shunt tubes, lower shunt tubes go up to be equipped with pneumatic little valve and mass flowmeter on the shunt tubes be equipped with pneumatic big valve and mass flowmeter on the shunt tubes down, the utility model discloses a numerical value of setting on two shunt tubes can learn gas flow's total amount, then just can constantly adjust two pneumatic valves up to suitable proportion according to the numerical value on the mass flowmeter, make gas flow's fluctuation steady, solved and conventionally used a valve can cause the more big problem of flow fluctuation.
Description
Technical Field
The utility model relates to a throw the material equipment field, in particular to gaseous white carbon black production air flow stably throws material device.
Background
In the production process of fumed silica, air is used as a main reaction raw material, and because the gas flow is large and the pressure is high, the control and adjustment of the flow become difficult, and if a valve is selected for adjustment, the fluctuation of the flow is large, the product quality is controlled disadvantageously, and the fluctuation of the specific surface area is large.
Disclosure of Invention
The utility model aims to provide a: the utility model provides a stable feeding device of air flow in fumed silica production, through setting up the numerical value on two shunt tubes, can learn air flow's total amount, then just can be according to the numerical value on the mass flow meter constantly adjust two pneumatic valves until suitable proportion, make air flow's fluctuation steady, solved and used a valve routinely and can cause the great problem of flow fluctuation.
The utility model adopts the technical scheme as follows:
the utility model provides a stable material device of throwing of air flow in fumed silica production be equipped with diverging device on the pipeline, diverging device includes shunt tubes, lower shunt tubes go up to be equipped with pneumatic little valve and mass flowmeter on the shunt tubes be equipped with pneumatic big valve and mass flowmeter down on the shunt tubes.
When the pneumatic flow control valve is used, the flow quantity which needs to be controlled respectively can be obtained by adding the numerical values displayed by the mass flow meters arranged on the two shunt pipes, then the pneumatic big valve and the pneumatic small valve are adjusted, the gas flow is distributed according to the proportion of 4:1, namely the pneumatic big valve controls 80% of the flow, and the pneumatic small valve controls 20% of the flow.
The utility model discloses a numerical value of setting on two shunt tubes can learn gas flow's total amount, then just can be according to the numerical value on the mass flow meter constantly adjust two pneumatic valves until suitable proportion, make gas flow's fluctuation steady, solved and used a valve can cause the undulant great problem of flow conventionally.
Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:
1. the utility model relates to a stable feeding device of air flow in fumed silica production through setting up the numerical value on two shunt tubes, can learn gas flow's total amount, then just can be according to the numerical value on the mass flow meter constantly adjust two pneumatic valves until suitable proportion, make gas flow's undulant steady, solved and used a valve routinely and can cause the more big problem of flow fluctuation.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
Reference numerals in the drawings indicate:
1-pneumatic small valve, 2-pneumatic big valve and 3-mass flow meter.
Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples, the exemplary embodiments of the present invention and the description thereof are only used for explaining the present invention, and are not intended as limitations of the present invention, and the connection in the specification is welding or riveting in the common knowledge, and the size ratio between each component in the specification does not represent the size ratio of each component in actual use.
The present invention will be described in detail with reference to fig. 1.
Example 1
The utility model provides a stable material device of throwing of air flow in fumed silica production be equipped with diverging device on the pipeline, diverging device includes shunt tubes, lower shunt tubes go up to be equipped with pneumatic little valve 1 and mass flowmeter 3 on the shunt tubes be equipped with pneumatic big valve 2 and mass flowmeter 3 on the shunt tubes down.
When the pneumatic flow control valve is used, the numerical values displayed by the mass flowmeters 3 arranged on the two shunt pipes are added to obtain the flow quantity which needs to be controlled respectively, then the pneumatic big valve 2 and the pneumatic small valve 1 are adjusted, the gas flow is distributed according to the proportion of 4:1, namely the pneumatic big valve 2 controls 80% of the flow, and the pneumatic small valve 1 controls 20% of the flow.
The utility model discloses a numerical value of setting on two shunt tubes can learn gas flow's total amount, then just can be according to the numerical value on the mass flow meter constantly adjust two pneumatic valves until suitable proportion, make gas flow's fluctuation steady, solved and used a valve can cause the undulant great problem of flow conventionally.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions conceived by the inventive work within the technical scope disclosed by the present invention.
