Description

Technical Field

[0001] The utility model relates to the technical field of solvent storage devices, and specifically relates to a waste solvent storage device. Background Technique

[0002] The storage of waste solvents is an important link involving environmental protection, safety and health, and compliance. When storing, it is necessary to select a container with good sealing performance for storage to ensure that the solvent will not volatilize or leak. At the same time, the container material should be resistant to solvent corrosion to avoid accidents such as container rupture.

[0003] Existing waste solvent storage devices are usually a closed container, which can only play a simple storage role and cannot regulate the temperature of the solvents stored therein. As a result, some solvents will change in properties due to temperature changes, which will in turn affect subsequent recycling and treatment measures. At the same time, some waste solvents may generate waste gas during storage, increasing the air pressure in the container. If the exhaust pressure reduction treatment is not carried out in time, it may lead to the deformation or even rupture of the container. Therefore, in view of the above problems, a waste solvent storage device is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a waste solvent storage device. A liquid injection cavity is formed between the outer heat-insulating barrel shell and the inner barrel of the solvent storage device, in which a cold source medium or a heat source medium can be injected, so as to regulate the waste solvent stored in the inner barrel. Moreover, the heat conduction fins can improve the heat exchange efficiency, enabling the cold and heat sources to better regulate the temperature of the waste solvent and avoiding the change of solvent properties due to temperature changes. In addition, when the air pressure in the inner barrel is too high, the self-sealing exhaust mechanism will open to discharge the waste gas. When the air pressure in the inner barrel decreases, the self-sealing exhaust mechanism will automatically close to play a sealing role, solving the technical problems in the prior art that the storage device cannot play a role in temperature regulation, easily causing the change of waste solvent properties due to temperature changes, which in turn affects subsequent recycling and treatment, etc., and that some waste solvents may generate waste gas during storage, increasing the air pressure in the container and easily causing the deformation or even rupture of the container.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A waste solvent storage device includes a storage barrel, on which a sealing cover is provided, a self-sealing exhaust mechanism provided on the sealing cover for discharging waste gas, and a waste gas absorption box for absorbing the discharged waste gas. Among them, the storage barrel includes an outer heat-insulating barrel shell and an inner barrel. A liquid injection cavity is formed between the outer heat-insulating barrel shell and the inner barrel, and they are fixedly connected to each other through connecting edges. A plurality of groups of heat conduction fins arranged in a circumferential array are provided on the outer wall of the inner barrel.

[0007] Through the above structural form, a liquid injection cavity is formed between the outer heat-insulating barrel shell and the inner barrel, in which a cold source medium or a heat source medium can be filled, so as to adjust the waste solvent stored in the inner barrel. Moreover, the heat-conducting fins can improve the heat exchange efficiency, enabling the cold and heat sources to better adjust the temperature of the waste solvent and preventing its solvent properties from changing due to temperature changes. In addition, when the air pressure in the inner barrel is too high, the self-sealing exhaust mechanism will open to discharge the waste gas, and when the air pressure in the inner barrel decreases, the self-sealing exhaust mechanism will automatically close to play a sealing role.

[0008] In a possible implementation manner, the self-sealing exhaust mechanism includes an exhaust cylinder communicated with the sealing cover. A cross-shaped frame and a closing ring are fixedly arranged in the cylinder from bottom to top. At the same time, a sliding plug located above the closing ring is slidably arranged in the cylinder. A tension spring is fixedly connected to the cross-shaped frame, and the end of the tension spring away from the cross-shaped frame is fixedly connected to the sliding plug.

[0009] Through the above structural form, in the normal state, the sliding plug fits with the closing ring to isolate the space inside and outside the barrel and play a sealing role. When the air pressure is too high, it will push the sliding plug to slide upward, causing the closing ring to open and play a pressure relief role. After the air pressure decreases, the tension spring will pull the sliding plug back to its original position to continue playing a sealing role.

[0010] In a possible implementation manner, a circular through-hole is formed in the middle of the closing ring, and the diameter of the sliding plug is larger than the aperture of the circular through-hole.

[0011] Through the above structural form, it can be ensured that when the sliding plug covers the closing ring, it can completely cover the through-hole in the middle of the closing ring to play a sealing role.

[0012] In a possible implementation manner, a plurality of exhaust grooves are formed in the inner wall of the upper part of the exhaust cylinder and are distributed in a circumferential array, and the bottom of the exhaust groove is on the same horizontal plane as the upper end surface of the closing ring.

[0013] Through the above structural form, when the sliding plug is separated from the closing ring, the waste gas can flow out through the middle of the closing ring and then be discharged from the exhaust cylinder through the exhaust grooves on the side.

[0014] In a possible implementation manner, a plurality of groups of bottom support plates are fixedly arranged on the upper end surface of the bottom plate of the outer heat-insulating barrel shell for supporting the inner barrel. A liquid discharge port is formed at the bottom of the outer heat-insulating barrel shell. A slope inclined towards the liquid discharge port is arranged on the upper end surface of the bottom plate of the outer heat-insulating barrel shell, and a sealing plug is arranged in the liquid discharge port.

[0015] Through the above structural form, the inner barrel can be suspended by the bottom support plates, enabling the cold and heat sources to contact the bottom of the inner barrel to achieve heat exchange. The liquid discharge port is used to discharge the cold and heat source media, facilitating the replacement of the cold and heat source media. The slope formed on the bottom plate of the outer heat-insulating barrel shell can prevent the cold and heat source media from not being discharged completely.

[0016] In a possible implementation, a liquid injection port communicating with the liquid injection cavity is provided on the upper end surface of the outer heat preservation barrel shell. At the same time, a plurality of connecting screws arranged in a circumferential array are fixedly provided on the upper end surface of the outer heat preservation barrel shell, which are used to cooperate with nuts to realize the airtight connection between the storage barrel and the sealing cover.

[0017] Through the above structural form, the provided liquid injection port provides a necessary structural basis for the injection of the cold and heat source medium, while the connecting screws provide a necessary structural basis for the airtight connection between the storage barrel and the sealing cover.

[0018] In a possible implementation, an air hood hermetically connected with an exhaust pipe is covered on the top of the exhaust pipe. At the same time, an absorption liquid is contained in the waste gas absorption box. The end of the exhaust pipe passes through the waste gas absorption box and is inserted into the absorption liquid, and an exhaust port is provided on the waste gas absorption box.

[0019] Through the above structural form, when the waste gas is discharged, it will enter the waste gas absorption box along the exhaust pipe to react with the absorption liquid, thereby playing a role in waste gas treatment and avoiding direct overflow of waste gas to pollute the environment.

[0020] In a possible implementation, a plurality of communicating notches arranged in an array are provided on the connecting edge, and the outer ends of the heat conducting fins do not contact the inner wall of the outer heat preservation barrel shell.

[0021] Through the above structural form, it can be ensured that neither the connecting edge nor the heat conducting fins will produce a blocking effect, and the cold and heat source medium is allowed to flow freely in the entire liquid injection cavity.

[0022] In summary, the present utility model includes the following beneficial technical effects:

[0023] A liquid injection cavity is formed between the outer heat preservation barrel shell and the inner barrel, in which a cold source medium or a heat source medium can be poured, thereby playing a role in adjusting the waste solvent stored in the inner barrel. Moreover, the heat conducting fins can improve the heat exchange efficiency, enabling the cold and heat sources to better adjust the temperature of the waste solvent, avoiding changes in the solvent properties due to temperature changes, and being beneficial to subsequent recycling and treatment processes.

[0024] In addition, when the air pressure in the inner barrel is too high, the self-sealing exhaust mechanism will open to discharge the waste gas.

[0031] The technical solutions in the embodiments of this application are to solve the problems in the above - mentioned background technology, and the general idea is as follows:

[0032] As Figure 1 - Figure 2 shown, a waste solvent storage device provided in this embodiment includes a storage barrel 1, on which a sealing cover 2 is provided, a self - sealing exhaust mechanism 3, which is provided on the sealing cover 2 for discharging waste gas, and a waste gas absorption box 4 for absorbing the discharged waste gas. Among them, the storage barrel 1 includes an outer thermal insulation barrel shell 11 and an inner barrel 12. A liquid injection cavity is formed by enclosing the outer thermal insulation barrel shell 11 and the inner barrel 12, and they are fixedly connected to each other through a connecting rib 13. A plurality of groups of heat - conducting fins 14 arranged in a circumferential array are provided on the outer wall of the inner barrel 12. Through the above - mentioned structural form, a liquid injection cavity is formed by enclosing the outer thermal insulation barrel shell 11 and the inner barrel 12, in which a cold - source medium or a heat - source medium can be filled, so as to adjust the waste solvent stored in the inner barrel 12. Moreover, the heat - conducting fins 14 can improve the heat - exchange efficiency, enabling the cold and heat sources to better adjust the temperature of the waste solvent and preventing its solvent properties from changing due to temperature changes. In addition, when the air pressure in the inner barrel 12 is too high, the self - sealing exhaust mechanism 3 will open to discharge the waste gas, and when the air pressure in the inner barrel 12 decreases, the self - sealing exhaust mechanism 3 will automatically close to play a sealing role.

[0033] As Figure 4As shown in the figure, the self - closing exhaust mechanism 3 includes an exhaust cylinder 31 communicating with the sealing cover 2. Inside the cylinder, a cross - shaped frame 32 and a closing ring 33 are fixedly arranged from bottom to top. At the same time, a sliding plug 34 is slidably arranged inside the cylinder above the closing ring 33. A tension spring 35 is fixedly connected to the cross - shaped frame 32, and the end of the tension spring 35 away from the cross - shaped frame 32 is fixedly connected to the sliding plug 34. Through the above - mentioned structural form, in the normal state, the sliding plug 34 fits with the closing ring 33, isolating the space inside and outside the barrel to play a sealing role. When the air pressure is too high, it will push the sliding plug 34 to slide upward, opening the closing ring 33 to play a pressure - relief role. After the air pressure decreases, the tension spring 35 will pull the sliding plug 34 back to its original position to continue playing a sealing role.

[0034] Among them, a circular through - hole is opened in the middle of the closing ring 33, and the diameter of the sliding plug 34 is larger than the aperture of the circular through - hole. Through the above - mentioned structural form, it can be ensured that when the sliding plug 34 covers the closing ring 33, it can completely cover the through - hole in the middle of the closing ring 33 to play a sealing role.

[0035] In addition, a number of exhaust grooves 36 are arranged in a circumferential array on the upper inner wall of the exhaust cylinder 31, and the bottom of the exhaust groove 36 is at the same horizontal plane as the upper end face of the closing ring 33. Through the above - mentioned structural form, when the sliding plug 34 is separated from the closing ring 33, the waste gas can flow out through the middle of the closing ring 33 and then be discharged from the exhaust cylinder 31 through the exhaust grooves 36 on the side.

[0036] As Figure 3 shown, a number of groups of bottom support plates 16 are fixedly arranged on the upper end face of the bottom plate of the outer heat - insulating barrel shell 11, which are used to support the inner barrel 12. A liquid discharge port 18 is opened at the bottom of the outer heat - insulating barrel shell 11. A slope inclined towards the liquid discharge port 18 is provided on the upper end face of the bottom plate of the outer heat - insulating barrel shell 11, and a sealing plug 19 is arranged in the liquid discharge port 18. Through the above - mentioned structural form, the inner barrel 12 can be suspended by the bottom support plates 16, enabling the cold and heat sources to contact the bottom of the inner barrel 12 to achieve heat exchange. The liquid discharge port 18 is used to discharge the cold and heat source medium, facilitating the replacement of the cold and heat source medium. The slope provided on the bottom plate of the outer heat - insulating barrel shell 11 can prevent the situation that the cold and heat source medium cannot be completely discharged.

[0037] As Figure 1 shown, a liquid injection port 15 communicating with the injection cavity is opened on the upper end face of the outer heat - insulating barrel shell 11. At the same time, a number of connecting screw rods 17 are fixedly arranged on the upper end face of the outer heat - insulating barrel shell 11 in a circumferential array, which are used to cooperate with nuts to realize the airtight connection between the storage barrel 1 and the sealing cover 2. Through the above - mentioned structural form, the opened liquid injection port 15 provides a necessary structural basis for the injection of the cold and heat source medium, while the connecting screw rods 17 provide a necessary structural basis for the airtight connection between the storage barrel 1 and the sealing cover 2.

[0038] As Figure 1 、 Figure 4As shown in the figure, a gas hood 37 is provided at the top of the exhaust stack 31, and a exhaust pipe 38 is hermetically connected thereto. At the same time, an absorption liquid is contained in the waste gas absorption box 4. The end of the exhaust pipe 38 passes through the waste gas absorption box 4 and is inserted into the absorption liquid. An exhaust port 41 is provided on the waste gas absorption box 4. With this structural form, when the waste gas is discharged, it will enter the waste gas absorption box 4 along the exhaust pipe 38 and react with the absorption liquid, thereby playing a role in waste gas treatment and preventing the waste gas from directly overflowing and polluting the environment.

[0039] As Figure 2 shown, a number of communication notches 131 distributed in an array are provided on the connecting edge 13, and the outer end of the heat-conducting fin 14 does not contact the inner wall of the outer heat-insulating barrel shell 11. With this structural form, it can be ensured that neither the connecting edge 13 nor the heat-conducting fin 14 will produce a blocking effect, and it is allowed for the cold and heat source media to freely flow in the entire liquid injection cavity.

[0040] The working principle and process of the present utility model are as follows:

[0041] A liquid injection cavity is formed by enclosing between the outer heat-insulating barrel shell 11 and the inner barrel 12, in which a cold source medium or a heat source medium can be filled, thereby playing a role in adjusting the waste solvent stored in the inner barrel 12. Moreover, the heat-conducting fin 14 can improve the heat exchange efficiency, enabling the cold and heat sources to better adjust the temperature of the waste solvent and preventing its solvent properties from changing due to temperature changes.

[0042] In addition, when the air pressure inside the inner barrel 12 is too high, the self-sealing exhaust mechanism 3 will open to discharge the waste gas. When the air pressure inside the inner barrel 12 decreases, the self-sealing exhaust mechanism 3 will automatically close to play a sealing role. Specifically, in the normal state, the sliding plug 34 fits with the sealing ring 33 to isolate the space inside and outside the barrel to play a sealing role. When the air pressure is too high, it will push the sliding plug 34 to slide upward, causing the sealing ring 33 to be opened to play a pressure relief role. And after the air pressure decreases, the tension spring 35 will pull the sliding plug 34 back to its original position to continue playing a sealing role. During the above process, the waste gas flowing out through the middle of the sealing ring 33 can be discharged through the exhaust groove 36 on the side to the exhaust stack 31.

[0043] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
