Description

Technical Field

[0001] The invention belongs to the technical field of oil wastewater treatment, and specifically relates to a concentrated liquid barrel for low-temperature evaporation of nylon ATY oil wastewater and a storage method thereof. Background Art

[0002] Nylon ATY (Air Textured Yarn) is a synthetic fiber and also a common textile raw material. A large amount of oil-mixed wastewater is generated during its production and preparation. For the treatment of oil-mixed wastewater, low-temperature evaporation and concentration can be used, and the concentrated wastewater can be transferred to a concentrated liquid barrel, which is sealed and stored in the concentrated liquid barrel and waits for subsequent transfer and treatment.

[0003] In the prior art, the concentrated liquid barrel for low-temperature evaporation of nylon ATY oil wastewater has a general sealing effect during use, after the concentrated liquid is collected and stored in the concentrated liquid barrel, and there is a certain degree of leakage. On the one hand, environmental gas and moisture can easily penetrate into the interior, causing the concentration ratio of the concentrated liquid to change. On the other hand, the odor in the concentrated liquid will dissipate in the ambient air, thereby reducing the ambient air quality. The current sealing effect is general, and there is a certain degree of leakage. When strengthening the seal, a special strengthening process is usually required. In fact, a series of operations need to be carried out when strengthening the seal. Strengthening the seal is troublesome and inefficient, and the use effect is not good.

[0004] In addition, for high-concentration concentrates, when post-processing is required after storage, the concentrate inside needs to be opened and discharged at the processing site. However, concentrates of a certain concentration have considerable adhesion, and there is a phenomenon of hanging on the wall when emptying, so that a large amount of concentrate remains on the inner wall of the concentrate barrel, affecting the next round of use. The actual concentrate is not treated cleanly, and more troublesome special cleaning is required. The cleaning wastewater after special cleaning contains concentrated liquid, which increases the amount of wastewater and has poor environmental protection effect. In addition, the obtained wastewater changes the original concentration of the concentrated liquid, affecting the subsequent treatment effect, and the comprehensive use effect is not good.

[0017] A method for storing concentrated liquid barrels for low-temperature evaporation of nylon ATY oil wastewater, comprising the following storage steps:

[0018] Step 1: Release the seal of the concentrated liquid barrel: Start the control component to move the guide moving component upward, and drive the sealing seat to move upward inside the barrel body, so that the push rod in the opening and closing component contacts the stop rod, and the sealing plug moves downward relative to the sealing seat and opens the sealing port;

[0019] Step 2: Concentrate injection: The concentrate outlet pipeline is sleeved into the collecting pipe. As the concentrate is injected, the concentrate is filled into the barrel through the collecting pipe, the connecting port and the sealing port.

[0020] Step 3: Store gas for standby use: After filling, open the gas injection pipe and pressurize the air to fill the gas storage cavity through the gas injection pipe;

[0021] Step 4: Seal the concentrated liquid barrel and strengthen the seal for the second time: Start the control component again to move the guide moving component downward. As the sealing seat moves downward, the opening and closing component is elastically reset by the spring 1, so that the sealing plug re-seals the sealing port, and continues to drive the sealing seat downward with the guide moving component. As the sealing seat moves downward, the concentrated liquid inside the barrel body is compressed. The internal hydraulic pressure of the concentrated liquid rises and acts on the strengthened sealing component at the bottom of the sealing plug, so that the protective cover moves upward and compresses the elastic airbag, so that the gas is further compressed in the elastic air ring through the intermediate tube, and the elastic air ring expands to fully fill the gap between the sealing plug and the sealing port, completing the strengthened seal;

[0022] Step 5: Self-cleaning discharge: open the discharge port, start the control component again and drive the sealing seat to move downward by guiding the moving component. The sealing seat moves downward along the inner wall of the barrel body, and the concentrated liquid is discharged through the discharge port. The concentrated liquid attached to the inner wall of the barrel body is scraped downward. When the arc surface at the bottom of the sealing seat is about to fit the arc surface of the inner wall of the barrel body, the pulling rope in the pulling component is tightened and the sealing head and the sealing protrusion at its bottom are pulled out of the assembly hole. The stored gas in the gas storage cavity is quickly ejected through the assembly hole, and the concentrated liquid remaining at the bottom of the inner surface of the barrel body is blown out to complete the self-cleaning discharge.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention drives the upward and downward movement of the guiding moving assembly by utilizing the control assembly to realize the upward and downward movement of the sealing seat with a semi-spherical bottom, thereby cooperating with the relative extrusion of the blocking rod and the opening and closing assembly in the collecting pipe to realize the opening and closing control of the sealing port inside the barrel body, and utilizes the elastic air ring and the elastic air bag respectively arranged on the outer side and the bottom of the sealing plug, and utilizes the sealing seat that can be moved downward. When the concentrated liquid is filled and stored, the hydraulic pressure of the stored concentrated liquid is enhanced by relying on the further downward movement, and the enhanced hydraulic pressure is used to react on the bottom of the opening and closing assembly. On the one hand, the sealing plug in the opening and closing assembly is pushed upward to fit the matching groove tightly, thereby improving the stability of the sealing end, and on the other hand, the hydraulic reaction force is used to push the elastic air bag at the bottom of the sealing plug to compress the internal gas into the elastic air ring, thereby utilizing the expanded elastic air ring to further fill the gap between the sealing plug and the sealing port, thereby realizing the effect of autonomously strengthening the seal, and the strengthening seal relies on the hydraulic pressure of the stored concentrated liquid, thereby saving the procedures for strengthening the seal, and the actual sealing performance is greatly improved, thereby effectively avoiding the leakage of the concentrated liquid and the pollution of the concentrated liquid by the external environment, while avoiding the leakage of the peculiar smell of the concentrated liquid, thereby maintaining the environmental quality, and the strengthening seal operation is simple and fast, and the use effect is good.

[0025] 2. The present invention realizes the up and down movement of the sealing seat by utilizing the above-mentioned control component to control the up and down movement of the guiding movable component, thereby realizing different target working requirements at different positions of the sealing seat. After rising, the barrel seal is released to realize the collection of concentrated liquid, and it is automatically sealed after resetting. After resetting, it continues to descend to squeeze the concentrated liquid to realize enhanced sealing. For the collection, storage and sealing of the entire concentrated liquid, only one set of motors in the control component needs to be rotated forward and reversely. The collection, storage and sealing operations are continuous without other redundant operations. The implementation steps are simple and fast, the operation is convenient and efficient, the leakage of odors during the operation process is reduced, and the comprehensive use effect is good.

[0026] 3. The present invention utilizes the control component to control the movement of the sealing seat again. When the stored concentrated liquid needs to be discharged, the gas inside the gas storage chamber is injected into the storage during the storage period. After the discharge port is opened, the descending sealing seat is used to scrape the attached concentrated liquid downward along the inner wall of the barrel body, and when the bottom hemispherical sealing seat is about to completely descend and close, the pulling component is automatically straightened and opened by descending a certain distance, so that the stored gas in the gas storage chamber is quickly discharged, so that a large amount of gas is quickly blown into the limited space at the bottom of the barrel body cavity, and the last residual concentrated liquid is automatically blown out. On the one hand, the liquid discharge effect of the concentrated liquid is greatly improved, the residue is avoided, and the emptying is ensured to be complete. On the other hand, the concentrated liquid barrel is automatically cleaned while being emptied. The concentrated liquid barrel is completely emptied during the emptying process, and there is no residue after emptying. The actual emptying quality is good, and the cleaning process is saved at the same time. The concentrated liquid barrel can be quickly put into the next round of storage and use, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The opening and closing assembly 10 includes a push rod 101, a sealing plug 102, a positioning rod 103 and a spring 104. The outside of the sealing plug 102 is provided with a reinforced sealing assembly 11;

[0040] The reinforced sealing assembly 11 includes an elastic air ring 111, an elastic air bag 112, an intermediate tube 113 and a protective cover 114. The elastic air ring 111 is fixedly sleeved on the outer surface of the sealing plug 102, the elastic air bag 112 is fixedly connected to the bottom of the sealing plug 102, the intermediate tube 113 is fixedly connected between the elastic air ring 111 and the elastic air bag 112, and the protective cover 114 is fixedly sleeved on the bottom of the elastic air bag 112.

[0041] First embodiment: When in use, first start the control component 4, so that the motor 42 rotates forward and drives the threaded shaft 43 to rotate, so that the cross plate 52 in the guide moving component 5 cooperates with the sliding rod 51 to move up along the threaded shaft 43, and drives the sealing seat 7 to move up inside the barrel body 1, so that the push rod 101 in the opening and closing component 10 moves upward to the collecting tube 3 and contacts the blocking rod 6, so that the blocking rod 6 squeezes the push rod 101, and the sealing plug 102 moves downward relative to the sealing seat 7 and opens the sealing port 9. At this time, the spring 104 is stretched to sleeve the concentrated liquid outlet pipeline in the collecting tube 3. As the concentrated liquid is injected, the concentrated liquid is filled into the barrel body 1 through the collecting tube 3, the connecting port 8, and the sealing port 9. After the filling is completed, the gas injection pipe 13 is opened, and the air is pressurized and filled into the gas storage chamber 1 through the gas injection pipe 13. 2, the control component 4 is started again, so that the motor 42 is reversed, and the guiding moving component 5 is moved down and reset. As the sealing seat 7 moves downward, the opening and closing component 10 is elastically reset by the spring 104, so that the sealing plug 102 re-seals the sealing port 9, and the guiding moving component 5 continues to drive the sealing seat 7 to move downward. As the sealing seat 7 moves downward, the concentrated liquid inside the barrel body 1 is compressed, and the internal hydraulic pressure of the concentrated liquid increases and acts on the reinforced sealing component 11 at the bottom of the sealing plug 102, and the hydraulic pressure pushes the protective cover 114, so that the protective cover 114 moves up and compresses the elastic airbag 112 on the top, so that the gas is further compressed in the elastic air ring 111 through the intermediate tube 113, and the elastic air ring 111 expands to fully fill the gap between the sealing plug 102 and the sealing port 9, thereby completing the reinforced seal.

[0042] First, by utilizing the control component 4 to drive the upward and downward movement of the guiding moving component 5, the upward and downward movement of the sealing seat 7 with a semi-spherical bottom is realized, thereby cooperating with the relative extrusion of the blocking rod 6 and the opening and closing component 10 in the collecting pipe 3 to realize the opening and closing control of the sealing port 9 inside the barrel body 1, and utilizing the elastic air ring 111 and the elastic air bag 112 respectively arranged on the outer side and the bottom of the sealing plug 102, and utilizing the sealing seat 7 that can move downward, when the concentrated liquid is filled and stored, the hydraulic pressure of the stored concentrated liquid is enhanced by further downward movement, and the enhanced hydraulic pressure is used to react on the bottom of the opening and closing component 10, so as to push the sealing plug 102 in the opening and closing component 10 on the one hand. It fits tightly upwards to the matching groove 16 to improve the stability of the sealing end. On the other hand, the hydraulic reaction force is used to push the elastic air bag 112 at the bottom of the sealing plug 102 to compress the internal gas into the elastic air ring 111, so that the expanded elastic air ring 111 is used to further fill the gap between the sealing plug 102 and the sealing port 9, thereby achieving the effect of self-enhanced sealing. The enhanced sealing relies on the liquid pressure of the stored concentrated liquid, which saves the enhanced sealing procedures and greatly improves the actual sealing performance, effectively avoiding the leakage of the concentrated liquid and the contamination of the concentrated liquid by the external environment. At the same time, the leakage of the odor of the concentrated liquid is avoided, and the environmental quality is maintained. The enhanced sealing operation is simple and fast, and the use effect is good.

[0043] In addition, by utilizing the above-mentioned control component 4 to control the up and down movement of the guiding movable component 5, the up and down movement of the sealing seat 7 is realized, thereby achieving different target working requirements at different positions of the sealing seat 7, and the seal of the barrel body 1 is released after rising to realize the collection of the concentrated liquid, and it is automatically sealed after resetting, and the seal is enhanced when the concentrated liquid is squeezed downward after resetting. For the collection, storage and sealing of the entire concentrated liquid, only one set of motors 42 in the control component 14 need to be rotated forward and reversely to realize it. The collection, storage and sealing operations are continuous without other redundant operations. The implementation steps are simple and fast, the operation is convenient and efficient, the leakage of odors during the operation and processing is reduced, and the comprehensive use effect is good.

[0044] Second embodiment: When it is necessary to discharge the concentrated liquid for waste liquid treatment, open the discharge port 2, start the control component 4 again and drive the sealing seat 7 to move downward along the inside of the barrel body 1 by guiding the moving component 5.

The rapidly purged airflow sweeps out the concentrated liquid remaining at the bottom of the inner surface of the barrel body 1, completing the self-cleaning discharge.

[0045] Firstly, by utilizing the control component 4 to control the movement of the sealing seat 7 again, when the stored concentrated liquid needs to be discharged, the gas inside the gas storage chamber 12 is injected and stored during the storage period.

On the one hand, the liquid discharge effect of the concentrated liquid is greatly improved, residue is avoided, and complete emptying is ensured. On the other hand, automatic cleaning is realized while the concentrated liquid barrel is emptied. The concentrated liquid barrel is completely emptied during the emptying process, and there is no residue after emptying.

[0053] By utilizing the pulling assembly 14 to maintain the internal sealing of the air storage chamber 12 when it is not straightened, the rigid rope is sealed more effectively by a sealing sleeve arranged on the outside, and the pulling rope 141 of the rigid rope itself avoids elastic deformation and leakage, while ensuring that it will not elastically extend during subsequent tightening, thereby ensuring that the sealing head 142 and the sealing protrusion at the bottom of the sealing head 142 are pulled out to achieve air release, thereby blowing and cleaning the residual concentrated liquid in the local cavity, and the sealing protrusion further improves the sealing effect, and the total length of the pulling rope 141 is less than the upper and lower distances of the inner cavity of the barrel body 1.

[0054] A method for storing concentrated liquid barrels for low-temperature evaporation of nylon ATY oil wastewater, comprising the following storage steps:

[0055] Step 1: Unsealing the concentrated liquid barrel: Start the control assembly 4, so that the guide moving assembly 5 moves upward, and drives the sealing seat 7 to move upward inside the barrel body 1, so that the push rod 101 in the opening and closing assembly 10 contacts the stop rod 6, and the sealing plug 102 moves downward relative to the sealing seat 7 and opens the sealing port 9;

[0056] Step 2: Concentrate injection: The concentrate outlet pipeline is sleeved in the collecting pipe 3. As the concentrate is injected, the concentrate is filled into the barrel 1 through the collecting pipe 3, the connecting port 8 and the sealing port 9;

[0057] Step 3: Storing gas for standby use: After filling, open the gas injection pipe 13, and pressurize the air to fill the gas storage chamber 12 through the gas injection pipe 13;

[0058] Step 4: Seal the concentrated liquid barrel and strengthen the seal for the second time: start the control component 4 again, so that the guide moving component 5 moves downward, and as the sealing seat 7 moves downward, the opening and closing component 10 is elastically reset by the spring 104, so that the sealing plug 102 re-seals the sealing port 9, and continues to drive the sealing seat 7 to move downward. As the sealing seat 7 moves downward, the concentrated liquid inside the barrel body 1 is compressed, and the internal hydraulic pressure of the concentrated liquid rises and acts on the strengthening sealing component 11 at the bottom of the sealing plug 102, so that the protective cover 114 moves upward and compresses the elastic airbag 112, so that the gas is further compressed in the elastic air ring 111 through the intermediate tube 113, and the elastic air ring 111 expands to fully fill the gap between the sealing plug 102 and the sealing port 9, completing the strengthening seal;

[0059] Step 5: Self-cleaning discharge: open the discharge port 2, start the control component 4 again and drive the sealing seat 7 to move downward by guiding the moving component 5, the sealing seat 7 moves downward along the inner wall of the barrel body 1, and the concentrated liquid is discharged through the discharge port 2, and the concentrated liquid attached to the inner wall of the barrel body 1 is scraped downward. When the arc surface at the bottom of the sealing seat 7 is about to fit the arc surface of the inner wall of the barrel body 1, the pulling rope 141 in the pulling component 14 is tightened and the sealing head 142 and the sealing protrusion at the bottom thereof are pulled out from the assembly hole 17, and the stored gas in the gas storage chamber 12 is quickly ejected through the assembly hole 17, and the concentrated liquid remaining at the bottom of the inner surface of the barrel body 1 is blown out to complete the self-cleaning discharge.
