A throttling pipe for acid distribution

Abstract

This utility model discloses a throttling and flow-reducing pipe for acid separation, relating to the technical field of acid separation equipment. Specifically, it is a throttling and flow-reducing pipe for acid separation, comprising a pipe body. A flow regulating component is fixedly connected to the surface of the pipe body. A control component is fixedly installed at the middle of the upper surface of the flow regulating component. A visualization component is fixedly connected to the upper surface of the flow regulating component. In use, the device is installed onto the acid separation equipment with bolts. When controlling the flow rate of concentrated sulfuric acid, rotating the control wheel causes the nut to rotate and drive the screw downward, thereby moving the flow regulating box downward and compressing the space inside the pipe body. This reduces the flow rate of concentrated sulfuric acid, preventing excessive flow of concentrated sulfuric acid in the pipe body and subsequent delivery pipelines, which could lead to increased pressure. This avoids affecting the delivery of concentrated sulfuric acid during separation and also prevents uneven acid separation, thus improving the throttling and flow-reducing effect.

Description

Technical Field

[0001] This utility model relates to the field of acid separation equipment technology, specifically to a throttling and flow-reducing pipe for acid separation. Background Technology

[0002] Concentrated sulfuric acid refers to a solution containing a high concentration of sulfuric acid. Generally speaking, concentrated sulfuric acid refers to a sulfuric acid solution with a concentration higher than a certain threshold, usually referring to sulfuric acid with a concentration of 95% or higher. Concentrated sulfuric acid has a wide range of applications in laboratories and industrial production.

[0003] The existing pipelines used for acid separation have poor flow control for concentrated sulfuric acid, which can easily lead to an excessive amount of concentrated sulfuric acid in the pipeline during the transportation of concentrated sulfuric acid, causing the pressure to exceed the preset value, affecting the transportation effect of concentrated sulfuric acid during acid separation, and resulting in uneven acid separation. Utility Model Content

[0004] The purpose of this utility model is to provide a throttling and flow-reducing pipe for acid separation. By setting up a pipe body, flow regulation component, control component and visualization component, it solves the problem that the existing pipelines used for acid separation have poor flow control effect on concentrated sulfuric acid, which can easily lead to excessive pressure in the pipeline during the transportation of concentrated sulfuric acid, resulting in accidents, affecting the transportation effect of concentrated sulfuric acid separation and causing uneven acid separation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flow-limiting and flow-reducing pipe for acid separation, comprising a pipe body, a flow regulating component fixedly connected to the surface of the pipe body, a control component fixedly installed at the middle of the upper surface of the flow regulating component, and a visualization component fixedly connected to the upper surface of the flow regulating component.

[0006] The flow regulating assembly includes an regulating frame fixedly connected to the upper surface of the pipe body, a sealing gasket fixedly connected around the inner wall of the regulating frame, a flow regulating box inserted into the inside of the regulating frame, and a screw fixedly connected to the upper surface of the flow regulating box.

[0007] Preferably, the control component includes a mounting base fixedly connected to the middle of the upper surface of the adjustment frame, a bearing is fixedly installed inside the mounting base, and a nut is rotatably connected to the mounting base through the bearing.

[0008] Preferably, the visualization component includes a support rod fixedly connected to the upper surface of the adjustment frame, a connecting seat fixedly connected to the top of the support rod, and a scale plate fixedly connected to the lower surface of the connecting seat.

[0009] Preferably, a control wheel is fixedly connected to the surface of the nut, and a hole is opened on the upper surface of the screw, with the scale plate inserted into the hole.

[0010] Preferably, flanges are fixedly connected to both ends of the pipe body, and a circular arc groove is provided on one side of the flange, with a sealing ring snapped into the inside of the circular arc groove.

[0011] Preferably, a rectangular groove is formed on the surface of the tube body, and the rectangular groove is adapted to the adjustment frame.

[0012] This utility model provides a throttling and downflow tube for acid separation, which has the following beneficial effects:

[0013] In use, this equipment is installed onto the acid separation equipment using bolts. When controlling the concentrated sulfuric acid flow rate, rotating the control wheel causes the nut to rotate and drive the screw downwards, thus moving the flow regulating box downwards. This compresses the space inside the pipe, reducing the concentrated sulfuric acid flow rate and preventing excessive flow in the pipe and subsequent delivery pipelines, which could lead to increased pressure. This avoids affecting the delivery of concentrated sulfuric acid during separation and prevents uneven separation, improving the throttling and flow reduction effect. Furthermore, personnel can determine the movement distance of the flow regulating box by observing the screw displacement distance on the scale plate as the screw moves downwards, thus assessing the concentration of sulfuric acid flow limits and facilitating adjustments based on actual usage.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a flow-limiting and flow-reducing pipe for acid separation, including a pipe body 1. A flow regulating component is fixedly connected to the surface of the pipe body 1. A control component is fixedly installed at the middle of the upper surface of the flow regulating component. A visualization component is fixedly connected to the upper surface of the flow regulating component.

[0024] The flow regulating component includes an regulating frame 2 fixedly connected to the upper surface of the tube body 1. Sealing gaskets 3 are fixedly connected around the inner wall of the regulating frame 2. A flow regulating box 4 is inserted into the inside of the regulating frame 2. A screw 5 is fixedly connected to the upper surface of the flow regulating box 4. The flow rate of concentrated sulfuric acid in the tube body 1 is controlled by the up and down movement of the flow regulating box 4. The sealing gaskets 3 are in contact with the flow regulating box 4 to prevent the concentrated sulfuric acid from flowing upward and affecting the flow control.

[0025] The control component includes a mounting base 6 fixedly connected to the middle of the upper surface of the regulating frame 2. A bearing 7 is fixedly installed inside the mounting base 6. A nut 8 is rotatably connected to the mounting base 6 through the bearing 7. In use, by rotating the nut 8, the screw 5 moves up and down, thereby driving the flow regulating box 4 to move up and down, controlling the space inside the pipe body 1, thereby achieving the purpose of controlling the flow. Since the flow regulating box 4 cannot rotate, the screw 5 moves up and down when the nut 8 rotates.

[0026] The visualization component includes a support rod 9 fixedly connected to the upper surface of the adjustment frame 2. A connecting seat 10 is fixedly connected to the top of the support rod 9, and a scale plate 11 is fixedly connected to the lower surface of the connecting seat 10. The position of the scale plate 11 is fixed by the support rod 9. When the screw 5 descends, the scale plate 11 is exposed, and the operator can observe the scale on the scale plate 11 to understand the descending distance of the screw 5, so as to facilitate the operator to control the descending distance of the screw 5 accordingly.

[0027] A control wheel 12 is fixedly connected to the surface of the nut 8. A hole is opened on the upper surface of the screw 5, and a scale plate 11 is inserted into the hole. The control wheel 12 is used to facilitate the rotation of the nut 8 by the operator, thus making it easy for the operator to operate.

[0028] Both ends of the pipe body 1 are fixedly connected to flanges 13. A circular arc groove is opened on one side of the flange 13. A sealing ring 14 is snapped into the inside of the circular arc groove. After the flange 13 is installed by the sealing ring 14, a sealing effect is achieved to prevent concentrated sulfuric acid from leaking out.

[0029] A rectangular groove is provided on the surface of the tube body 1, and the rectangular groove is adapted to the adjustment frame 2.

[0030] All components in this solution are made of corrosion-resistant materials, such as 316 stainless steel and polytetrafluoroethylene. Among them, the sealing gasket 3 and the sealing ring 14 are made of neoprene rubber, which has good corrosion resistance to avoid damage to the equipment during use.

[0031] The component was damaged by concentrated sulfuric acid, affecting the flow control effect.

[0032] Specifically, when this acid-dispensing throttling and depressurizing pipe is in operation / use: During use, the device is installed onto the acid-dispensing equipment using bolts. When controlling the concentrated sulfuric acid flow rate, rotating the control wheel 12 causes the nut 8 to rotate and drive the screw 5 downwards, thus moving the flow regulating box 4 downwards. This compresses the space within the pipe body 1, reducing the concentrated sulfuric acid flow rate and preventing excessive pressure increases in the pipe body 1 and subsequent delivery pipelines. This avoids affecting the delivery of concentrated sulfuric acid during dispensing and prevents uneven dispensing. Furthermore, personnel can determine the movement distance of the flow regulating box 4 by observing the downward movement of the screw 5, which exposes the scale plate 11. This allows for easy adjustment based on actual usage.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
