Description

Technical Field

[0001] The present invention relates to the technical field of storage containers, and in particular to an explosion-proof drum suitable for environmental protection chemical industry use. Background Art

[0002] A ton barrel is a large storage and transportation container, also known as an intermediate bulk container, with a standard capacity of approximately 1000 liters. Due to its moderate capacity and convenient loading and unloading characteristics, it is widely used in the environmental protection chemical industry. According to the different stored materials, ton barrels are divided into various models, such as insulated ton barrels, explosion-proof ton barrels, and leak-proof ton barrels. Especially the explosion-proof ton barrels have significantly improved safety and environmental protection performance through material optimization and structural innovation on the basis of traditional designs.

[0003] In the application in the environmental protection chemical industry, before using a ton barrel, the external sealing cover needs to be opened in advance so that materials can be injected into it through a filling machine. However, there is a time difference between opening the sealing cover and actual filling. During this period, impurities in the external air are likely to enter the interior of the ton barrel, thus affecting the purity of the subsequent filled materials. This pollution risk will reduce the product quality and even cause safety problems in chemical production. Therefore, special attention needs to be paid to controlling this process to ensure the high purity and environmental protection requirements of the materials. Summary of the Invention

[0020] In addition, particularly preferably, the elastic coefficient of the sealing cloth is greater than that of the communicating hose to store gas in the communicating hose.

[0021] Compared with the prior art, the present invention has the following advantages: 1. The present invention seals the feed pipe through the sealing cloth. When the storage cylinder is filled, the liquid outlet pipe of the filling machine is docked and fitted with the feed pipe to form a sealed filling environment, and at the same time, the sealing of the feed pipe by the sealing cloth is released, reducing the probability of external impurities entering the inside of the storage cylinder during filling and improving the purity of the liquid.

[0022] 2. A wrap-around seal is formed on the outside of the feed pipe through the cover, and then the sealing cloth seals the inside of the feed pipe. At this time, the feed pipe is double-sealed by the cover and the sealing cloth, improving the sealing strength of the storage cylinder and reducing the probability of external water vapor entering the storage cylinder and causing pollution.

[0023] 3. By automatically adjusting the position of the feed pipe to follow the liquid discharge pipe of the filling machine, the central axes of the two are made to coincide, ensuring smooth liquid flow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0034] When preparing to use a ton barrel for filling materials, it is usually necessary to first remove the external plugging cover. However, there is a time difference between removing the plugging cover and actually starting the filling. During this period, dust, moisture, and other impurities in the external air may enter the interior of the ton barrel, thereby affecting the purity of the materials after filling. This pollution risk may lead to a decline in product quality and even cause a series of problems in subsequent processing.

[0035] An explosion-proof material barrel suitable for environmental protection chemical industry, as Figures 1-7 shown, includes: a support frame 1; a storage cylinder 2, disposed within the support frame 1, the storage cylinder 2 being fixedly connected and communicating with a discharge head 3, the storage cylinder 2 being provided with a feed pipe 4, the feed pipe 4 communicating with the storage cylinder 2, the storage cylinder 2 being provided with a cover 5 for plugging the feed pipe 4; a sliding sleeve 6, rotatably and slidably connected to the feed pipe 4, a sealing cloth 7 for plugging the feed pipe 4 being fixedly connected between the sliding sleeve 6 and the feed pipe 4, the sealing cloth 7 being elastic; a driving assembly, disposed on the feed pipe 4, for controlling the communication relationship between the feed pipe 4 and the outside.

[0036] In the above solution, the support frame 1 is made of stainless steel, with strong corrosion resistance and high structural strength. The storage cylinder 2 is made of a material with excellent anti-static performance and impact resistance. For example, high-density polyethylene (HDPE) added with a conductive material can be used to reduce the risk of static electricity accumulation. The discharge head 3 is located at the bottom of the storage cylinder 2 and is in the structure of a faucet, which can enable the materials in the storage cylinder 2 to flow outwards. A groove is provided at the top of the storage cylinder 2, and the feed pipe 4 is located inside this groove. The sealing cloth 7 is made of silicone, with good sealing performance and elasticity, and has chemical inertness, being not easily reactive with other chemical substances. In the initial state, the sliding sleeve 6 is located at the upper part of the feed pipe 4, maintaining the sealing cloth 7 in a torsional deformation state. The cross-section of the sealing cloth 7 is in the shape of an 'n'. By fixing one end of the sealing cloth 7 and rotating the other end, the middle part of the sealing cloth 7 is twisted and entangled to a point (similar to the existing structure of a twist cup), thereby enabling the sealing cloth 7 to block the feed pipe 4. When the storage cylinder 2 is being filled, the liquid outlet pipe of the filling machine is docked and fitted with the feed pipe 4 to form a sealed filling environment, and at the same time, the blockage of the feed pipe 4 by the sealing cloth 7 is released, preventing external impurities from entering its interior during the filling of the storage cylinder 2 and affecting the purity of the subsequent liquid.

[0037] Specifically, as Figure 5 and Figure 6As shown in the figure, the driving component includes: a first elastic member 201 disposed between the feed pipe 4 and the sliding sleeve 6, and an inclined chute 202 is provided on the outer part of the feed pipe 4; a clamping block 203 fixedly connected to the sliding sleeve 6, and the clamping block 203 slides within the inclined chute 202.

[0038] In the above solution, the first elastic member 201 is a spring and is initially in a compressed state, used to apply a stable upward thrust to the sliding sleeve 6, that is, in the state without external force, the sliding sleeve 6 is stably positioned at the upper part of the feed pipe 4, improving the sealing stability of the sealing cloth 7 to the feed pipe 4. The number of inclined chutes 202 can be freely set according to actual conditions and are circumferentially and equally spaced on the outer wall of the feed pipe 4. The number of clamping blocks 203 is the same as the number of inclined chutes 202, and the clamping blocks 203 slide along adjacent inclined chutes 202, causing the sliding sleeve 6 to twist, and then causing the sealing cloth 7 to undergo a torsional deformation, releasing the sealing of the sealing cloth 7 to the feed pipe 4.

[0039] Working principle: When it is necessary to fill the liquid into the storage cylinder 2, it is necessary to unscrew the cover 5 in advance to separate the cover 5 from the storage cylinder 2, and then place the device at the filling position. The filling machine starts to perform the filling operation on the device. At this time, since the sealing cloth 7 is in a torsional deformation state, that is, the sealing cloth 7 is in a sealing state for the feed pipe 4, impurities in the external air cannot enter the interior of the storage cylinder 2. The liquid outlet pipe of the filling machine moves downward and contacts the sliding sleeve 6, and pushes the sliding sleeve 6 to move downward synchronously. At the same time, the first elastic member 201 is compressed. The downward movement of the sliding sleeve 6 drives a number of clamping blocks 203 circumferentially and equally spaced thereon to move synchronously. The clamping blocks 203 slide along adjacent inclined chutes 202, causing the sliding sleeve 6 to rotate while moving downward along the feed pipe 4. The sliding sleeve 6 drives the sealing cloth 7 to twist synchronously, and the sealing cloth 7 releases the torsional state, enabling the liquid outlet pipe of the filling machine to communicate with the feed pipe 4. Then, the filling machine is started to perform the filling operation until the filling is completed.

[0040] After the storage cylinder 2 is filled, the filling machine drives the liquid outlet pipe to reset upward, and the liquid outlet pipe of the filling machine releases the extrusion of the sliding sleeve 6. At this time, the first elastic member 201 drives the sliding sleeve 6 to move upward synchronously. At the same time, the clamping blocks 203 slide back along the adjacent inclined chutes 202, causing the sliding sleeve 6 to rotate back until the sliding sleeve 6 resets to the initial position, causing the sealing cloth 7 to twist again to form a seal for the feed pipe 4. Then, the cover 5 is screwed onto the storage cylinder 2. When it is necessary to perform the filling operation on the device again, repeat the above steps. Before the storage cylinder 2 is filled, the present application seals the feed pipe 4 through the sealing cloth 7, and when the storage cylinder 2 is filled, the liquid outlet pipe of the filling machine is docked and fitted with the feed pipe 4 to form a sealed filling environment, and the sealing of the sealing cloth 7 to the feed pipe 4 is released, reducing the probability of external impurities entering the interior of the storage cylinder 2 during filling and improving the purity of the liquid.

[0041] After the filling of this application is completed, vehicle transfer operations are often required. During the vehicle transfer process, this device is inevitably jolted and vibrates, resulting in a weakened docking seal between the sealing cap 5 and the storage cylinder 2, reducing the sealing strength and allowing external water vapor to enter the storage cylinder 2. At this time, the docking of the sealing cap 5 and the storage cylinder 2 causes the grooves of the sealing cap 5 and the storage cylinder 2 to jointly form an enclosed seal around the feed pipe 4, and then the sealing cloth 7 seals the inside of the feed pipe 4. At this time, the feed pipe 4 is double-sealed by the sealing cap 5 and the sealing cloth 7, greatly improving the sealing strength of the storage cylinder 2 and reducing the probability of external water vapor entering the storage cylinder 2 and causing pollution.

[0042] In a further embodiment, as Figures 2-4 shown, the feed pipe 4 is slidably connected to the storage cylinder 2. A number of second elastic members 301 are circumferentially distributed between the feed pipe 4 and the storage cylinder 2. A flexible ring 302 is fixedly connected and communicated between the feed pipe 4 and the storage cylinder 2; the sliding sleeve 6 is provided with an inclined ring surface 303; the feed pipe 4 is fixedly connected with a locking ring 304, and the storage cylinder 2 is slidably connected with a pressing frame 305. The pressing frame 305 is used to press and limit the locking ring 304, and the sealing cap 5 is used to limit the pressing frame 305; a third elastic member 306 is provided between the storage cylinder 2 and the pressing frame 305.

[0043] In the above solution, the second elastic member 301 is a spring. The number of the second elastic members 301 can be freely set, and several second elastic members 301 are circumferentially equidistantly distributed between the feed pipe 4 and the storage cylinder 2 for driving the feed pipe 4 to reset. The flexible ring 302 is made of silica gel and can adapt to the position change of the feed pipe 4. The inclined ring surface 303 on the sliding sleeve 6 faces the central axis of the feed pipe 4. The liquid injection pipe of the external filling machine contacts the inclined ring surface 303 on the sliding sleeve 6, so that the liquid injection pipe of the filling machine drives the feed pipe 4 to move through the sliding sleeve 6. The locking ring 304 is provided with an annular inclined surface, and the pressing frame 305 is provided with an inclined surface that fits the annular inclined surface on the locking ring 304. The pressing frame 305 presses the locking ring 304 through the fitting of the inclined surfaces to lock the position of the feed pipe 4. The third elastic member 306 is a spring and is in a compressed state in the initial state, and is used to push the pressing frame 305 upward to separate from the annular inclined surface of the locking ring 304 and release the pressing state of the locking ring 304. By automatically following the change of the liquid outlet pipe of the filling machine for the position of the feed pipe 4, the central axes of the two are made to coincide to ensure smooth liquid flow.

[0044] When this device performs filling operations, this device is usually conveyed to the lower part of the filling machine through a conveyor belt. The vibration of the conveyor belt will change the position of this device, resulting in the inability to ensure the alignment of the central axis of the liquid outlet pipe of the filling machine and the central axis of the filling port, resulting in an unsmooth liquid flow phenomenon when this device is filling.

[0045] Working principle: During the filling process of this device, when the capping 5 is separated from the storage cylinder 2, the extrusion of the extrusion frame 305 by the capping 5 is released. The third elastic member 306 elongates from the compressed state and pushes the extrusion frame 305 to slide upward along the storage cylinder 2. At the same time, the extrusion limit of the locking ring 304 by the extrusion frame 305 is released, and the feed pipe 4 is converted into a free sliding state.

[0046] After the feed pipe 4 is converted to the free state, the liquid outlet pipe of the filling machine starts to move downward for filling. When the central axis of the liquid outlet pipe of the filling machine is misaligned with the central axis of the feed pipe 4, the liquid outlet pipe of the filling machine first contacts the inclined ring surface 303 on the sliding sleeve 6 and squeezes the sliding sleeve 6 through the inclined ring surface 303, causing the sliding sleeve 6 to generate a horizontal movement force. The sliding sleeve 6 drives the feed pipe 4 to move along the storage cylinder 2. At the same time, the second elastic member 301 located in the moving direction of the feed pipe 4 is compressed. This continues until the central axes of the feed pipe 4 and the liquid outlet pipe of the filling machine coincide. At this time, the feed pipe 4 stops horizontal movement, and the flexible ring 302 deforms to adapt to the position change of the feed pipe 4, ensuring the smooth injection of liquid. By automatically following the change of the liquid outlet pipe of the filling machine in the position of the feed pipe 4, the central axes of the two coincide, ensuring the smooth flow of liquid.

[0047] When the filling of this device is completed, that is, when the filling machine drives the liquid outlet pipe to move upward, the extrusion of the sliding sleeve 6 is released. At this time, the deformed second elastic member 301 resets and pushes the feed pipe 4 back to the initial state, and the flexible ring 302 returns to the initial state. Then the capping 5 is screwed into the storage cylinder 2 again. At this time, the capping 5 presses down on the extrusion frame 305, and at the same time, the third elastic member 306 is compressed, causing the extrusion frame 305 to squeeze the locking ring 304 and lock it. At this time, the screwing of the capping 5 is completed. When the above problems occur again, repeat the above steps.

[0048] In a further embodiment, as Figures 4-7 shown, a sealing airbag 401 is fixedly connected to the sliding sleeve 6. The sealing airbag 401 is wrapped by a sealing cloth 7 and fits the feed pipe 4. An annular shell 402 is fixedly connected to the feed pipe 4, and a pushing ring 403 is fixedly connected to the sliding sleeve 6. The annular shell 402 is in sealing sliding connection with the pushing ring 403. A communication hose 404 is fixedly connected and communicated between the sealing airbag 401 and the annular shell 402. The communication hose 404 penetrates the sliding sleeve 6. The annular shell 402 is provided with a plurality of pressure holes 405 for reducing the sliding resistance of the pushing ring 403. The communication hose 404 is elastic and has a length allowance to keep itself in a loose state at all times for adapting to the position change of the sliding sleeve 6. The elastic coefficient of the sealing cloth 7 is greater than that of the communication hose 404 for storing gas in the communication hose 404.

[0049] In the above solution, the material of the sealing airbag 401 is polyethylene, which is convenient for customization and processing, and at the same time has good sealing performance, durability and chemical corrosion resistance. The sealing airbag 401 is located on the upper side of the sliding sleeve 6, the pushing ring 403 is located on the lower side of the sliding sleeve 6, the material of the connecting hose 404 is silica gel, the number of the air pressure holes 405 on the annular shell 402 can be freely set, and they are equally spaced on the upper side of the annular shell 402 to reduce the downward sliding resistance of the pushing ring 403. The connecting hose 404 has enough length to adapt to the position change of the sliding sleeve 6, avoiding unnecessary stretching of the connecting hose 404 and reducing the service life of the connecting hose 404. The sealing airbag 401 drives the sealing cloth 7 to fit and block the bottom of the liquid injection pipe of the filling machine, reducing the probability of liquid leakage. At the same time, the sealing cloth 7 is further straightened to make the sealing cloth 7 fit the inner wall of the feed pipe 4, ensuring the smoothness of liquid injection. The elastic coefficient of the sealing cloth 7 is greater than that of the connecting hose 404, that is, after the sealing cloth 7 is stretched to the limit state, it cannot be further stretched by the expansion force of the sealing airbag 401, and the remaining gas will be stored in several connecting hoses 404 for subsequent filling of the sealing airbag 401 to ensure that the sealing airbag 401 always closely adheres to the sealing cloth 7 and maintains the straightened state of the sealing cloth 7.

[0050] When the filling operation is carried out on this device, due to the long-term use of the liquid injection pipe of the filling machine, the lower side will be uneven due to corrosion and aging, resulting in a gap between the liquid injection pipe of the filling machine and the filling port after docking, causing liquid leakage during the filling process.

[0051] Working principle: When the liquid injection pipe of the filling machine drives the sliding sleeve 6 to move downward, the sliding sleeve 6 drives the pushing ring 403 at the bottom to move synchronously, so that the pushing ring 403 slides downward along the annular shell 402. The gas in the annular shell 402 enters the sealing airbag 401 through the connecting hoses 404 that are equally spaced in the circumferential direction. The sealing airbag 401 begins to expand and drives the sealing cloth 7 to fit the inner wall of the liquid outlet pipe of the filling machine. And the expansion force of the sealing airbag 401 drives the sealing cloth 7 to gradually tighten, so that the sealing cloth 7 fits the inner wall of the feed pipe 4. In this way, until the sliding sleeve 6 stops moving downward, the pushing ring 403 is driven by the sliding sleeve 6 to move downward, and gas is gradually injected into the sealing airbag 401, so that the sealing airbag 401 drives the sealing cloth 7 to fit and block the bottom of the liquid injection pipe of the filling machine, reducing the probability of liquid leakage. At the same time, the sealing cloth 7 is further straightened to make the sealing cloth 7 fit the inner wall of the feed pipe 4, ensuring the smoothness of liquid injection.

[0052] After the sealing cloth 7 has been used for a long time, it will be stretched after continuous twisting and releasing, resulting in the sealing cloth 7 being unable to fit tightly against the inner wall of the feed pipe 4, thereby affecting the smooth injection of liquid. After the pushing ring 403 slides along the annular shell 402 and pushes the gas in the annular shell 402 into the sealing airbag 401 through a number of connecting hoses 404, the sealing airbag 401 is restricted by the sealing cloth 7 and cannot continue to expand. At this time, the remaining gas will be stored in a number of connecting hoses 404 and cause the connecting hoses 404 to expand. If the sealing cloth 7 is stretched, the sealing cloth 7 will release the restriction on the sealing airbag 401. At this time, the excess gas stored in the connecting hoses 404 will enter the sealing airbag 401, causing the sealing airbag 401 to expand further, straightening the sealing cloth 7 again by the sealing airbag 401, and improving the flow degree of the liquid.

[0053] When the filling of the device is completed, that is, when the sliding sleeve 6 moves upward to reset to the initial state, the sliding sleeve 6 drives the pushing ring 403 to reset upward synchronously, so that the gas in the sealing airbag 401 and the connecting hoses 404 resets and flows into the annular shell 402. When the device needs to be filled again, the above steps are repeated.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
