Description

Technical Field

[0001] This utility model relates to the technical field of phosphate ester production equipment, specifically a sight glass device for a phosphate ester washing material storage tank. Background Technology

[0002] The water washing process in phosphate ester production is a crucial purification step, its fundamental purpose being to remove residual impurities from the synthesis process and ensure that the product meets industrial or electronic grade purity requirements. During the production of phosphate ester chemical products, the washed material needs to be allowed to settle and separate into layers in a storage tank due to density differences, so that the lower layer of water can be removed promptly.

[0003] To maximize the discharge of lower-layer water in a single operation, sight glasses are typically installed on the side of the storage tank to observe the stratification interface. The traditional method involves installing a connecting-tube sight glass (a transparent glass tube connecting the upper and lower parts of the tank) on the side wall to observe the liquid level interface. However, the mixture of phosphate ester and water is highly emulsifiable and viscous, and narrow-diameter sight glasses are easily adhered to by viscous materials. This viscous material can obstruct the view, making observation unclear. Furthermore, since the transparent tube connects to both ends of the tank, it cannot be cleaned. Additionally, under conditions of unclear observation, phosphate ester material can easily be discharged during the lower-layer water discharge, resulting in material loss. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a sight glass device for a phosphate ester washing material storage tank, including a vertical pipe 1, with several horizontal pipes 2 connected to the storage tank on the side of the vertical pipe 1, and a movable cleaning component inside the vertical pipe 1. The cleaning component includes a threaded post 5, with two threaded rings 51 threadedly connected to the outer periphery of the threaded post 5, and an annular pad 52 for cleaning the inner wall of the vertical pipe 1 on the outer periphery of the threaded rings 51. The top of the vertical pipe 1 is provided with a driver to drive the cleaning component to move up and down, and the bottom of the vertical pipe 1 is provided with a discharge assembly. The driver can drive the threaded post 5, the threaded rings 51 and the annular pad 52 to move down. During the downward movement of the annular pad 52, the viscous material attached to the inner wall of the vertical pipe 1 is cleaned, and the material is discharged through the bottom of the vertical pipe 1.

[0015] After the wiping effect of the annular pad 52 is reduced, the servo motor 3 is controlled to move the lower threaded ring 51 to the outside of the vertical tube 1. Then, the lower threaded ring 51 and the annular pad 52 can be removed and replaced. The upper threaded ring 51 and the annular pad 52 are always located inside the vertical tube 1, which plays a positioning role for the threaded column 5.

[0016] Furthermore, the driver includes a servo motor 3 mounted on the top of the vertical tube 1. The output shaft of the servo motor 3 is mounted with a screw 4 via a coupling. The threaded column 5 is threadedly connected to the screw 4, and there is a coaxiality deviation between the axis of the threaded column 5 and the axis of the screw 4. The coaxiality deviation installation method can prevent the threaded column 5 from rotating when it moves up and down, thus controlling the servo motor 3 to work. The servo motor 3 drives the threaded column 5 to move via the screw 4.

[0017] Furthermore, a valve 21 is provided on the horizontal pipe 2.

[0018] Furthermore, the discharge assembly includes a threaded plug 7, a threaded hole 6 at the bottom of the vertical pipe 1, and the threaded plug 7 is threadedly connected to the threaded hole 6. A vertically arranged discharge hole is provided in the middle of the threaded plug 7, and a discharge pipe 72 communicating with the discharge hole is provided at the bottom of the threaded plug 7. A discharge valve 73 is provided on the discharge pipe 72. A sealing post 71 is provided on the upper surface of the threaded plug 7. A through hole communicating with the discharge hole is provided on the sealing post 71. When it is necessary to clean the inner wall of the vertical pipe 1, the valve 21 is closed first, and then the discharge valve 73 is opened to drain the water. The remaining phosphate ester mixture solution in the vertical pipe 1 is recovered by the recycling equipment. The threaded plug 7 is rotated and removed, and the threaded plug 7 drives the sealing post 71 to move out from the bottom of the vertical pipe 1.

[0019] The servo motor 3 used in this utility model is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies and will not be described in detail here.

[0020] When using: During observation, valve 21 is opened, and vertical pipe 1 forms a communication device with storage tank through horizontal pipe 2. When the solution in storage tank separates into layers, the lower layer water can enter vertical pipe 1 through horizontal pipe 2 located below the water level, while the mixed solution in horizontal pipe 2 can flow into storage tank through the upper horizontal pipe 2. This ensures that the layering interface observed in vertical pipe 1 is closer to the layering interface in storage tank. When it is necessary to clean the inner wall of the vertical pipe 1, first close valve 21, then open discharge valve 73 to drain the water, and recover the remaining phosphate ester mixture solution in the vertical pipe 1 through the recycling equipment; Rotate and remove the threaded plug 7, which causes the sealing column 71 to move out from the bottom of the vertical tube 1. Then, the servo motor 3 is controlled to work. The servo motor 3 drives the threaded column 5, threaded ring 51 and annular pad 52 to move down through the screw 4. During the downward movement of the annular pad 52, the viscous material attached to the inner wall of the vertical pipe 1 is cleaned, and the material is discharged through the bottom of the vertical pipe 1. When the wiping effect of the annular pad 52 decreases, the lower threaded ring 51 and annular pad 52 can be removed and replaced. The upper threaded ring 51 and annular pad 52 are always located inside the vertical tube 1, which plays a positioning role for the threaded column 5.

[0021] This invention employs a sight glass tube with multiple transverse channels, which allows for timely exchange of solutions between the vertical tube 1 and the storage tank. It also enables the cleaning of viscous materials from the inner wall of the vertical tube 1, improving the observation effect and facilitating the precise discharge of the lower layer of water. This prevents the loss of phosphate ester materials and makes the product convenient to use.

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