Description

Technical Field

[0001] The utility model relates to the technical field of organic solvent transfer, in particular to a special barrel cover for novel organic solvent transfer. Background Technique

[0002] In chemical production, for the transfer of flammable, explosive and volatile liquid materials, first of all, the empty barrel should be airtight, and the empty barrel needs to be inerted in advance, and nitrogen should be continuously protected throughout the transfer process to prevent air and the like from entering the barrel, resulting in material insecurity or preventing the material from volatilizing into the environment and causing harm to the human body. The prior art usually uses a feeding cover (also known as a barrel cover) to achieve the airtightness and inerting of the barrel. The currently commonly used feeding cover drills three holes in the top of the original barrel cover, namely a material pipeline hole, a nitrogen pipeline hole and a tail gas absorption and discharge hole. The hole diameter is slightly larger than the outer diameter of the corresponding pipeline to facilitate the insertion of the corresponding pipeline. However, there are the following defects in actual operation: 1) When feeding, the material pipe is in a free state and shakes greatly, and the operator needs to hold the material pipe by hand all the time; 2) Since the hole diameter is slightly larger than the outer diameter of the pipeline, these three holes cannot be completely airtight during the feeding process, it is very difficult to ensure that there is no leakage of materials during the operation, and there is also a great risk in terms of safety. The gap is very easy to introduce air, and the material is very easy to leak from the drilled holes during nitrogen inerting, resulting in a dangerous operation environment and extremely easy to cause safety accidents; 3) There is no liquid level display function, and the operator cannot accurately judge whether the barrel is full of materials. Content of the Utility Model

[0003] The purpose of the utility model is to provide a special barrel cover for novel organic solvent transfer, so as to solve at least one of the problems put forward in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A special barrel cover for novel organic solvent transfer, including a barrel cover body. A material pipe seat, an observation hole seat and a liquid level gauge seat are fixedly arranged on the top of the barrel cover body. The observation hole seat is located at the center of the top of the barrel cover body, and the material pipe seat and the liquid level gauge seat are located on both sides of the observation hole seat. The material pipe seat is fixedly connected with a material pipe in a pluggable and sealed manner. The observation hole seat is fixedly connected with an observation sight glass, and the liquid level gauge seat is fixedly connected with a float type liquid level gauge. The side wall of the barrel cover body is fixedly connected with a tail gas absorption interface, a vacuum reserved interface and a nitrogen interface in sequence from top to bottom. The cover opening of the barrel cover body is provided with a connection thread matching the barrel.

[0006] Further, the material pipe seat is cylindrical. A groove is provided at the top of the material pipe seat, and a first sealing ring is installed in the groove. A groove is provided at the bottom of the material pipe seat, and an elastic ring is installed in the groove. The material pipe seat is threadedly connected with a screw cap. The material pipe passes through the screw cap, the elastic ring and the material pipe seat, and one end extends out of the screw cap, and the other end is inserted into the bottom of the material bucket. The screw cap is sealed with the material pipe seat through the first sealing ring. After the bottom end of the screw cap presses the elastic ring, the elastic ring squeezes inward and presses the material pipe.

[0007] Further, the material pipe seat is in a flange shape. A flange is fixedly connected to the material pipe near the top. The material pipe passes through the material pipe seat and is inserted into the bottom of the material bucket and is fixedly connected to the material pipe seat through the flange. A sealing gasket is installed between the flange and the material pipe seat.

[0008] Further, 1-2 spare hole seats are fixedly arranged at the top of the bucket cover body. The spare hole seats, the material pipe seat and the liquid level gauge seat are annularly distributed. A groove is provided at the top of the spare hole seat, and a second sealing ring is installed in the groove. The spare hole seat is threadedly connected with a plug cock. The plug cock is hermetically connected with the spare hole seat through the second sealing ring.

[0009] Further, side handles are symmetrically and fixedly connected to the side wall of the bucket cover body, and the side handles are provided with static clamp clamping points.

[0010] Further, a bevel head interface is fixedly arranged at the top of the material pipe. The tail gas absorption interface, the vacuum reserved interface and the nitrogen interface are bevel head interfaces.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model is convenient and practical, and has a low manufacturing cost. It is applicable to the turnover and transfer of various organic solvent liquids in the production of the chemical industry and the fine chemical industry. During the transfer process, it provides inerting for the materials, operates in a closed manner, can prevent leakage and moisture absorption, and can meet the safety use requirements of the existing chemical industry for flammable, explosive and volatile liquid materials.

[0013] 1) By arranging the material pipe seat and the material pipe, the material pipe and the material pipe seat can be detachably and hermetically fixedly connected. During the feeding process of the material bucket, the shaking of the material pipe is avoided, and there is no need for the operator to always hold the material pipe by hand, thus releasing the operator's hands and reducing the labor burden of the operator.

[0014] 2) Sealing rings or sealing gaskets are provided for the material pipe, the float type liquid level gauge and the spare hole seat. The tail gas absorption interface, the vacuum reserved interface and the nitrogen interface are bevel head interfaces for convenient sealing connection. During the feeding process of the material bucket, the material pipe, the float type liquid level gauge, the spare hole seat, the tail gas absorption interface, the vacuum reserved interface and the nitrogen interface can all be effectively sealed, ensuring that the materials do not leak and reducing the safety risk.

[0015] 3) The utility model is provided with a float type liquid level gauge, which is connected to the integrated service platform. When the liquid material fills the barrel, after the integrated service desk receives the signal from the float type liquid level gauge, it automatically closes the peristaltic pump, stops feeding, and gives an alarm to prompt the operator that the material has been filled up.

The barrel cover body 1 is in the shape of a cylindrical barrel. A material pipe seat 6, an observation hole seat 11 and a liquid level gauge seat 13 are welded on the top of the barrel cover body 1. The materials of the material pipe seat 6, the observation hole seat 11 and the liquid level gauge seat 13 are all stainless steel. The observation hole seat 11 is located at the center of the top of the barrel cover body 1. The material pipe seat 6 and the liquid level gauge seat 13 are located on both sides of the observation hole seat 11. The material pipe seat 6 is detachably and fixedly sealed and connected with a material pipe 10. The observation hole seat 11 is fixedly connected with an observation sight glass 12, which is convenient for observing the actual situation inside the material barrel. The observation sight glass 12 and the observation hole seat 11 are of a flange connection structure and a gasket is arranged between them. The liquid level gauge seat 13 is fixedly connected with a float type liquid level gauge 14. The float type liquid level gauge 14 and the liquid level gauge seat 13 are of a flange connection structure and a gasket is arranged between them. The side wall of the barrel cover body 1 is welded with a tail gas absorption interface 3, a vacuum reserved interface 4 and a nitrogen interface 5 from top to bottom in sequence, which are convenient for connecting with a tail gas absorption device 22, a vacuum pump 24 and a nitrogen source 23 located on the comprehensive service desk 18 through pipelines respectively. A connection thread matching the material barrel is arranged on the cover opening 101 of the barrel cover body 1, and it can be thread-sealed and connected with the material barrel.

[0023] Among them, the material pipe seat 6 is in the shape of a cylinder. A groove is opened at the top of the material pipe seat 6 and a first sealing ring 8 is installed in the groove. A groove is opened at the bottom of the material pipe seat 6 and an elastic ring 9 is installed in the groove. The material pipe seat 6 is thread-connected with a screw cap 7. The screw cap 7 is made of tetrafluoro material. The material pipe 10 passes through the screw cap 7, the elastic ring 9 and the material pipe seat 6 and one end extends out of the screw cap 7, and the other end is inserted into the bottom of the material barrel (not shown in the figure). The screw cap 7 is sealed with the material pipe seat 6 through the first sealing ring 8. After the bottom end of the screw cap 7 presses the elastic ring 9, the elastic ring 9 is squeezed inward and presses the material pipe 10, playing a dual role of fixing the material pipe 10 and sealing.

[0024] Among them, two spare hole seats 15 are welded on the top of the barrel cover body 1. The spare hole seats 15 are made of stainless steel. The spare hole seats 15 and the material pipe seat 6 and the liquid level gauge seat 13 are distributed in a ring shape. A groove is opened at the top of the spare hole seat 15 and a second sealing ring 17 is installed in the groove. The spare hole seat 15 is thread-connected with a plug 16. The plug 16 is made of tetrafluoro material. The plug 16 is sealed and connected with the spare hole seat 15 through the second sealing ring 17. The spare hole seat 15 can be used for installing a feed pipe or a discharge pipe to meet the requirements of two-way or multi-way operation of simultaneous feeding and discharging. When not in use, the spare hole seat 15 can be blocked with the plug 16.

[0025] Among them, side handles 2 are symmetrically welded on the side wall of the barrel cover body 1, which serve as a barrel opener and a fixed handle, facilitating the tightening or loosening of the barrel cover body 1 on the material barrel, being convenient and practical. The side handles 2 are provided with static clamp fixing points, which are convenient for clamping static clamps.

[0026] Among them, a reducing socket interface is fixedly arranged at the top of the material pipe 10, which is convenient for connecting with a peristaltic pump 21 through a hose. The tail gas absorption interface 3, the vacuum reserved interface 4, and the nitrogen interface 5 are reducing socket interfaces, which are convenient for connecting corresponding devices through hoses.

[0027] The working principle of the present utility model:

[0028] First, loosen and remove the original barrel cover of the empty barrel, and then tighten the barrel cover body 1 on the empty barrel. The silicone tube 19 is sleeved on the tail gas absorption interface 3 and the nitrogen interface 5 and connected to the tail gas absorption device 22 and the nitrogen source 23 of the integrated service desk 18 respectively. The silicone tube 19 is clamped by a clamp at the sleeve to prevent the silicone tube 19 from falling off and play a sealing role. The open end of a silicone tube with one end closed is sleeved on the vacuum reserved interface 4 and clamped by a clamp to seal the vacuum reserved interface 4 (when necessary, the vacuum reserved interface 4 can be connected to a vacuum pump 24 through a silicone tube to extract the vacuum of the barrel, and the vacuum pump 24 is located at the integrated service desk 18). Each silicone tube is marked clearly to prevent confusion and avoid danger. The side handle 2 clamps an electrostatic clamp, and the material pipe 10 is inserted into the barrel through the material pipe seat 6. Adjust the position of the material pipe 10, tighten the screw cap 7 to seal the pipe seat 6 and press the elastic ring 9 to squeeze inward to fix and seal the material pipe 10. The reducing socket interface at the top of the material pipe 10 is connected to the peristaltic pump 21 of the integrated service desk 18 through a silicone tube. The float type liquid level gauge 14 is electrically connected to the integrated service desk 18. Various pipelines are integrated into a bundle through the cable bundle 20 to improve the 6S management of the operation site. Turn on the tail gas absorption device 22, and then turn on the nitrogen source 23 to perform nitrogen inerting treatment on the barrel. After the inerting is completed, the peristaltic pump 21 can be started to start the barrel filling operation. During the barrel filling operation, slightly open the nitrogen and continuously carry out inerting protection until the barrel filling operation ends. During the barrel filling process, the situation inside the barrel can be observed at any time through the sight glass 12. When the liquid material fills the barrel, after the integrated service desk 18 receives the signal from the float type liquid level gauge 14, the peristaltic pump 21 is automatically turned off, the feeding is stopped, and an alarm is given to prompt the operator that the material has been filled. After the barrel is filled, remove the electrostatic clamp, turn off the tail gas absorption device 22 and the nitrogen source 23, and disconnect the barrel cover body 1 from each pipeline. Loosen and remove the barrel cover body 1, and quickly cover the original barrel cover. Replace another barrel and repeat the above barrel filling operation until all barrels are filled, and then clean up the site. After the present utility model is used up, wash it with alcohol and dry it naturally or blow it dry with nitrogen to avoid cross contamination. The whole is bagged and a "cleaned" label is pasted and hung up. The cleaning and maintenance are simple and fast. Embodiment
