Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a quantitative feeding device for a reaction vessel used in the preparation of diisooctyl phosphate. Background Technology

[0002] Diisooctyl phosphate, also known as P204 phosphate, is an acidic phosphorus-based extractant primarily used for the extraction and separation of rare earth elements, non-ferrous metals (including cobalt, nickel, gold, copper, indium, etc.), and electrolytic metals. It can also be used in the pharmaceutical, printing and dyeing, and petrochemical wastewater treatment industries. It is also a widely used industrial extractant in nuclear fuel (uranium) extraction, rare earth element separation, and non-ferrous metal extraction. P204 phosphate is insoluble in water but soluble in organic solvents such as acetone and ethanol.

[0003] Diisooctyl phosphate is generally prepared by oxyphosphoric acid and octanol. The main process steps are esterification, alkali washing, acidification, water washing, alcohol evaporation, and de-alcoholization. Esterification and other reactions require a reaction vessel for chemical reaction. The feeding of the chemical reaction material needs to be quantitative to meet the reaction conditions. In Chinese utility model patent CN221906969U, entitled "A Quantitative Feeding Device for a Reaction Vessel for the Preparation of Diisooctyl Phosphate," the relative position between the electrode and the electrode plate is changed by rotating the locking screw to adjust the limiting ring. After adjustment, the telescopic rod extends to push the sleeve towards... The material moves downward, causing the movable rod, float, and scraper to move downward as well. The material enters the reactor body through the connecting pipe. As the float descends, the sliding rod moves accordingly. When the electrode and the electrode plate come into contact with each other, the control panel closes the telescopic rod and the solenoid valve, stopping the feeding and realizing the quantitative feeding of the resin raw material. The above application directly adds the material into the reactor during feeding, which is not suitable for conditions that require continuous and quantitative feeding. Furthermore, the preparation of diisooctyl phosphate requires the continuous addition of isooctanol into the reactor, making the above quantitative feeding device unsuitable for the preparation reaction of diisooctyl phosphate.

[0055] Connect the drive source 52, the electronically controlled valve 62, the transfer pump 72, and the control valve 76 to the switch and the power supply respectively;

[0056] Includes a reaction vessel body 1, which is used to prepare diisooctyl phosphate.

[0057] Support component 2, which is connected to the top of the reactor body 1;

[0058] The top of the support assembly 2 is connected to two symmetrically distributed metering cylinders 3;

[0059] The metering component 4 and the driving component 5 are provided in the inner cavity of the metering cylinder 3. The metering component 4 is connected to the driving component 5 in a transmission connection.

[0061] Liquid delivery component 7 is connected to the top of support component 2 and is connected to two metering cylinders 3 respectively. Liquid delivery component 7 is used to deliver material into the two metering cylinders 3 respectively.

[0062] In this technical solution, the liquid delivery component 7 can add materials into the metering cylinder 3. The metering component 4 in the metering cylinder 3 separates the materials. At the same time, the driving component 5 drives the metering component 4 to rotate. The metering component 4 can quantitatively separate and transfer the materials when they enter the metering cylinder 3 and add them into the reaction vessel body 1, so as to realize the continuous and quantitative addition of materials to facilitate the preparation of diisooctyl phosphate.

[0063] The support assembly 2 includes a support platform 21 and fixed side plates 22. The bottom of the support platform 21 is connected to two symmetrically distributed fixed side plates 22, and the bottom end of the fixed side plates 22 is connected to the top of the reactor body 1.

[0064] In this technical solution, the support component 2 can support the quantitative cylinder 3 and other structures.

[0065] The metering cylinder 3 has an inlet on its top surface and an outlet on its bottom surface;

[0066] The inlet and outlet are on the same vertical plane, but their center lines are not on the same vertical line.

[0067] In this technical solution, the center lines of the inlet and outlet are not on the same vertical line, which can prevent the material added to the metering cylinder 3 by the liquid delivery component 7 from directly entering the feeding component 6 and disrupting the metering operation.

[0068] The feeding assembly 6 includes a feeding pipe 61 and an electrically controlled valve 62. The two ends of the feeding pipe 61 are connected to the bottom of the support plate 21 and the top of the reactor body 1, respectively. The electrically controlled valve 62 is installed in the middle section of the feeding pipe 61.

[0069] In use, the on / off state of the feeding pipe 61 is controlled by the electric control valve 62.

[0070] The quantitative component 4 includes a rotating shaft 41, and a plurality of partition plates 42 are connected to the surface of the rotating shaft 41.

[0071] The partition plate 42 is connected to a side scraper 43, and the side of the side scraper 43 away from the partition plate 42 is in contact with the inner wall of the metering cylinder 3.

[0072] The upper and lower sides of the partition plate 42 are connected to upper and lower scraper strips 44, and the upper and lower scraper strips 44 on both sides are in contact with the inner wall of the top surface and the inner wall of the bottom surface of the metering cylinder 3, respectively.

[0073] In this technical solution, the quantitative component 4 can be used to quantitatively separate the material when it enters the quantitative cylinder 3.

[0074] The distance between two adjacent separator plates 42 located directly below the inlet on the top surface of the metering cylinder 3 is greater than the diameter of the inlet.

A preset hole is opened on the top surface of the metering cylinder 3. The top end of the rotating shaft 41 is rotatably connected to the top surface of the metering cylinder 3 through the preset hole.

[0076] The top end of the rotating shaft 41 is connected to the drive assembly 5 for transmission.

[0077] In use, the liquid delivery component 7 adds material to the two metering cylinders 3 respectively. At the same time, the drive component 5 drives the rotating shaft 41 to rotate, thereby driving the partition plate 42 to rotate. At this time, the material entering the metering cylinder 3 enters the compartments formed by multiple adjacent partition plates 42 in sequence. The material is quantitatively distributed by the compartments formed by two adjacent partition plates 42. Then the partition plate 42 continues to rotate, which drives the side scraper 43 and the upper and lower scraper 44 to rotate synchronously, thereby driving the material in the compartment to move. When the material moves to the discharge port, the material enters the feeding pipe 61 and then enters the reactor body 1, realizing continuous and quantitative feeding of the material.

[0078] It should be noted that the side scraper 43 and the upper and lower scraper 44 can not only transfer and pick up materials, but also prevent materials from adhering to the inner wall of the metering cylinder 3.

[0079] The drive assembly 5 includes a protective housing 51, which is connected to the top of the metering cylinder 3;

[0080] The inner wall of the protective housing 51 is connected to a drive source 52. The output end of the drive source 52 is connected to a main gear 53. A secondary gear 54 is meshed with the side of the main gear 53. The bottom of the secondary gear 54 is connected to the top of the rotating shaft 41.

[0081] In this technical solution, the driving component 5 drives the metering component 4 to operate and realize the feeding of the reaction vessel.

[0082] The bottom surface of the protective housing 51 is provided with a rotating hole, and the top end of the rotating shaft 41 is rotatably connected to the bottom surface of the protective housing 51 through the rotating hole.

[0083] In use, the drive source 52 drives the main gear 53 to rotate, which in turn drives the secondary gear 54 to rotate, and in turn drives the rotating shaft 41 to rotate.

[0084] By controlling the rotation speed of the drive source 52, the capacity entering the two adjacent partition plates 42 at a time can be controlled, thus achieving continuous and quantitative addition.

[0085] The liquid delivery assembly 7 includes a liquid storage tank 71, which is connected to the top of the support platform 21, and a transfer pump 72 is connected to the top of the liquid storage tank 71.

[0086] The inlet end of the transfer pump 72 is connected to an inlet pipe 73, which extends to the inner cavity of the liquid storage tank 71. The outlet end of the liquid storage tank 71 is connected to a three-way pipe 74, and transfer pipes 75 are connected to both sides of the three-way pipe 74.

[0087] The end of the transfer tube 75 away from the three-way tube 74 is connected to the top surface of the metering cylinder 3, and the transfer tube 75 is connected to the inner cavity of the metering cylinder 3 through the inlet.

[0088] In this technical solution, the liquid delivery component 7 can be used to deliver materials into the metering cylinder 3.

[0089] A control valve 76 is installed at one end of the transfer pipe 75 near the tee pipe 74.

[0090] In this technical solution, the on / off state of the transfer pipe 75 can be controlled by the control valve 76.

[0091] In use, the material stored in the storage tank 71 is pumped into the three-way pipe 74 by the transfer pump 72 and the inlet pipe 73, and then enters the transfer pipes 75 on both sides through the three-way pipe 74, and then enters the metering cylinder 3 through the inlet.

[0092] According to the feeding requirements, the control valve 76 is used to control the opening and closing of the corresponding transfer pipe 75, so as to control the usage status of the two metering cylinders 3 respectively.

[0093] The support plate 21 and the top surface of the reactor body 1 each have two symmetrically distributed connecting holes. The outlet on the bottom surface of the metering cylinder 3, the connecting hole on the support plate 21, the connecting hole on the reactor body 1, and the feeding pipe 61 are all on the same vertical line.

[0094] The upper end of the feeding pipe 61 is connected to the bottom of the metering cylinder 3, and the lower end is connected to the top surface of the reactor body 1. The metering cylinder 3 and the reactor body 1 are interconnected through the connecting hole, the feeding pipe 61 and the discharge port.

[0095] Control valve 76 and solenoid valve 62 can respectively control the opening and closing of the corresponding transfer pipe 75 and feeding pipe 61, thereby controlling the use or closure of the metering cylinder 3. When in use, one metering cylinder 3 can be opened for use, and the other metering cylinder 3 can be closed for prohibition of use, or both metering cylinders 3 can be opened and used together.
