Description

Technical Field

[0001] This invention relates to a dispensing arm for filling ton containers of tricresyl phosphite and its usage method. Background Technology

[0002] Tricresol phosphite (TCP) is an important organophosphorus chemical product widely used in PVC stabilizers, flame retardant plasticizers, and lubricant additives. Due to its high viscosity at room temperature, tendency to crystallize at low temperatures, and sensitivity to moisture, the filling process of TCP requires nitrogen protection and constant temperature heating. Currently, the industry commonly uses a fixed bottom discharge pipe to directly connect a flexible hose from the bottom of the production tank for ton-bottle filling.

[0003] However, the height of the discharge pipe end (injection nozzle) of this filling method is not adjustable during filling. It can only be adapted to the height of the barrel opening by manually lifting the ton barrel or raising the platform, which is labor-intensive and inefficient. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a dispensing arm for filling tungsten phosphate phosphate in ton containers and its usage method. The main dispensing arm can swing in the vertical plane through the vertical swing joint, and the dispensing nozzle can be raised and lowered by one hand. There is no need to move the ton container or raise the platform. It can adapt to different ton container inlet heights, shorten the filling preparation time, eliminate the need for manual lifting of the hose, greatly reduce the labor intensity of the operator, and improve the overall work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a liquid dispensing arm for filling ton drums of tricresol phosphite, including a tricresol phosphite production tank; The main discharge arm is connected directly to the discharge port of the tricresol phosphite production tank. The main discharge arm includes an upstream riser, a midstream swing pipe and a downstream injection pipe connected in series. The downstream injection pipe is provided with an injection nozzle at the end for insertion into the ton tank inlet. A vertical swing joint is provided between the upstream riser, the midstream swing pipe and the downstream injection pipe, so that the midstream swing pipe, the downstream injection pipe and the injection nozzle can swing up and down in the vertical plane relative to the tricresol phosphite production tank to adjust the height of the injection nozzle. The follow-up support arm is hinged at both ends to the midstream swing tube and the external fulcrum, respectively, to provide continuous support for the liquid outlet main arm under any swing angle. The relative height between the injection nozzle and the tricrete phosphite production tank can be changed by manipulating the vertical swing connector, so that the injection nozzle is aligned with the inlet of the ton container at different heights, thus avoiding leakage during the filling of tricrete phosphite.

[0006] As a preferred embodiment of the present invention, a support plate is provided on the lower surface of the middle part of the midstream swing tube, and two first fixing plates are provided on the upper surface of the support plate, with a space reserved between the two first fixing plates for inserting one end of the follower support arm.

However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0018] Example: like Figure 1 - Figure 5As shown, this embodiment proposes a liquid dispensing arm for filling a 16-ton container of tricresyl phosphite, including a tricresyl phosphite production tank; a main dispensing arm, the inlet of which is directly connected to the outlet of the tricresyl phosphite production tank; an upstream riser 1, a midstream swing pipe 2, and a downstream injection pipe 3 connected in series on the main dispensing arm; and an injection nozzle 4 at the end of the downstream injection pipe 3 for insertion into the inlet of the 16-ton container; a vertical swing connector, which is located between the upstream riser 1, the midstream swing pipe 2, and the downstream injection pipe 3, allowing the midstream swing pipe 2, the downstream injection pipe 3, and the injection nozzle 4 to... The nozzle 4 can swing up and down in the vertical plane relative to the tricresyl phosphite production tank to adjust its height. A follow-up support arm 5, with its two ends hinged to the midstream swing pipe 2 and an external fulcrum respectively, provides continuous support to the main dispensing arm at any swing angle. The main dispensing arm can swing in the vertical plane via a vertical swing connector, allowing for single-handed operation to raise and lower the nozzle 4 without moving the ton 16 or raising a platform. This adapts to different ton 16 inlet heights, shortens filling preparation time, eliminates the need for manual lifting of the hose, significantly reduces operator workload, and improves overall work efficiency. Furthermore, by manipulating the vertical swing connector, the relative height of the nozzle 4 to the tricresyl phosphite production tank can be changed, aligning the nozzle 4 with the ton 16 inlet at different heights and preventing tricresyl phosphite filling leakage.

[0019] A support plate 6 is provided on the lower surface of the middle part of the midstream oscillating tube 2. Two first fixing plates 7 are provided on the upper surface of the support plate 6. A space is reserved between the two first fixing plates 7 for inserting one end of the follower support arm 5, providing a lower fulcrum for the follower support arm 5 on the pipeline. The fulcrum is made into a U-shaped lug. A first rotating shaft 8 is inserted into the side of the two first fixing plates 7 that is close to each other. The two first rotating shafts 8 are respectively connected to one end of the follower support arm 5. The follower support arm 5 is hinged in the lug by the two first rotating shafts 8 to form a rotatable joint, realizing the hinge rather than the fixed connection, allowing the support arm to freely change the angle as the oscillating tube rises and falls. A support frame 9 is provided on the outside of the tricresol phosphite production tank. An mounting plate 10 is provided on the support frame 9. Two second fixing plates 11 are provided on the upper surface of the mounting plate 10. A space is reserved between the two second fixing plates 11 for inserting the other end of the follower support arm 5. An upper fulcrum lug is also provided at the other end of the follower support arm 5. A second rotating shaft 12 is provided on the opposite side of the two second fixing plates 11. The two second rotating shafts 12 are respectively connected to the other end of the follower support arm 5. Similarly, the lower end of the follower support arm 5 is hinged in the other lug by the two second rotating shafts 12 to achieve the hinge. In conjunction with the rotation of the follower support arm 5, a detachable conical guide cap is fitted on the outer periphery of the injection nozzle 4. An elastic sealing ring is provided at the lower end of the guide cap for automatic centering and sealing when inserted into the inlet of the ton tank 16.

[0020] The vertical swing joint includes a first rotary joint 13 and a second rotary joint 14. The first rotary joint 13 is located between the upstream riser 1 and the midstream swing pipe 2, splitting the height adjustment function into two stages. The first rotary joint 13 is responsible for the vertical swing between the upstream riser 1 and the midstream swing pipe 2. The second rotary joint 14 is located between the midstream swing pipe 2 and the downstream injection pipe 3. The addition of the second rotary joint 14 forms a second-stage swing, which coordinates with the vertical swing between the midstream swing pipe 2 and the downstream injection pipe 3. Both the first rotary joint 13 and the second rotary joint 14 are equipped with angle lockers, which can quickly lock the injection nozzle 4 at the required height. A control valve 15 is installed on the downstream injection pipe 3, with the valve directly integrated at the end of the rigid pipe, eliminating the need for a bottom valve or an additional hose valve.

[0021] A method for using the dispensing arm of a 16-ton filling tank for tricresyl phosphite is described below: S1. First, hold the midstream swing pipe 2 with both hands and slowly turn the first rotary joint 13 and the second rotary joint 14 to lift the midstream swing pipe 2 and the downstream injection pipe 3, and drive the injection nozzle 4 to follow and lift upward in the vertical plane, leaving a clearance greater than the height of the ton barrel 16. S2. As the midstream swing pipe 2, the downstream injection pipe 3 and the injection nozzle 4 are lifted, the first rotating shaft 8 and the second rotating shaft 12 rotate together with the follow-up support arm 5 to lift up, always supporting the midstream swing pipe 2 and preventing it from falling. S3. Move the empty ton container 16 directly below the injection nozzle 4 so that the center of the inlet of the container mouth coincides with the axis of the injection nozzle 4. S4. Reverse the first rotary joint 13 and the second rotary joint 14 to allow the midstream swing pipe 2, the downstream injection pipe 3 and the injection nozzle 4 to descend, so that the injection nozzle 4 is inserted into the inlet of the empty ton 16. S5. After confirming that the height of the injection nozzle 4 is appropriate, tighten the angle lock on the first rotary joint 13 to prevent swinging during the filling process; at this time, the follow-up support arm 5 still maintains slight pressure support to eliminate pipeline vibration. S6. Open the control valve 15 on the downstream injection pipe 3 to start filling.
