Description

Technical Field

[0001] The invention relates to the technical field of storage containers, and in particular to an explosion-proof barrel suitable for environmentally friendly chemical industry. Background Art

[0002] Ton barrels are large storage and transportation containers, also known as intermediate bulk containers. Their standard capacity is about 1,000 liters. With their moderate capacity and convenient loading and unloading features, they are widely used in the field of environmental protection and chemical industry. Depending on the stored materials, ton barrels are divided into various models, such as insulated ton barrels, explosion-proof ton barrels and leak-proof ton barrels. In particular, explosion-proof ton barrels have significantly improved their safety and environmental performance through material optimization and structural innovation based on traditional designs.

[0003] In the application of environmental protection chemical industry, the external sealing cap of the ton barrel needs to be opened in advance before use so that the material can be injected into the interior through the filling machine. However, there is a time difference between opening the sealing cap and the actual start of filling. During this period, impurities in the outside air can easily enter the interior of the ton barrel, thereby affecting the purity of the subsequent filling material. This pollution risk will reduce 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 material. Summary of the invention

[0007] In addition, it is particularly preferred that the feed pipe is slidably connected to the storage cylinder, a plurality of circumferentially distributed second elastic members are provided between the feed pipe and the storage cylinder, and the feed pipe and the storage cylinder are fixedly connected and communicated with a flexible ring.

[0008] Furthermore, it is particularly preferred that the sliding sleeve is provided with an inclined annular surface.

[0009] In addition, it is particularly preferred that the feed pipe is fixedly connected with a locking ring, the storage cylinder is slidably connected with an extrusion frame, the extrusion frame is used to extrusion lock the locking ring, and the sealing cover is used to limit the extrusion frame.

[0010] Furthermore, it is particularly preferred that a third elastic member is provided between the storage cylinder and the extrusion frame.

[0011] In addition, it is particularly preferred that the sliding sleeve is fixedly connected to a sealing airbag, the sealing airbag is wrapped by the sealing cloth, and the sealing airbag fits the feeding tube.

[0012] In addition, it is particularly preferred that the feed pipe is fixedly connected to an annular shell, the sliding sleeve is fixedly connected to a push ring, the annular shell and the push ring are sealingly and slidingly connected, the sealing airbag is fixedly connected to the annular shell and is connected by a connecting hose, the connecting hose passes through the sliding sleeve, and the annular shell is provided with a plurality of pressure holes, which are used to reduce the sliding resistance of the push ring.

[0013] In addition, it is particularly preferred that the connecting hose is elastic and has a length margin so that the connecting hose is always in a loose state to adapt to the position change of the sliding sleeve.

[0014] Furthermore, it is particularly preferable that the elastic coefficient of the sealing cloth is greater than the elastic coefficient of the communication hose so that the communication hose can store gas.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention seals the feed pipe by means of a sealing cloth, and when the storage cylinder is filled, the liquid outlet pipe of the filling machine is butted against the feed pipe to form a sealed filling environment, and at the same time, the sealing cloth is released to seal the feed pipe, thereby reducing the probability of external impurities entering the storage cylinder during filling, thereby improving the purity of the liquid.

[0016] 2. The feed pipe is sealed by covering it on the outside, and then the sealing cloth is used to seal the inside of the feed pipe. At this time, the feed pipe is doubly sealed by the cover and the sealing cloth, which improves the sealing strength of the storage tube and reduces the probability of contamination caused by external water vapor entering the storage tube.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is 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 only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0022] When preparing to use ton barrels for material filling, it is usually necessary to remove the external sealing cap first. However, there is a time difference between removing the sealing cap and actually starting filling. During this time, dust, moisture and other impurities in the outside air may enter the ton barrel, thereby affecting the purity of the material after filling. This contamination risk may lead to a decline in product quality and even cause a series of problems in subsequent processing.

[0023] An explosion-proof barrel suitable for environmental protection chemical industry, such as Figure 1-Figure 7 As shown, it includes: a support frame 1; a storage cylinder 2, which is arranged in the support frame 1, the storage cylinder 2 is fixedly connected and connected with a discharge head 3, the storage cylinder 2 is provided with a feed pipe 4, the feed pipe 4 is connected with the storage cylinder 2, and the storage cylinder 2 is provided with a cover 5 for blocking the feed pipe 4; a sliding sleeve 6, which is rotatably and slidably connected to the feed pipe 4, and a sealing cloth 7 for blocking the feed pipe 4 is fixedly connected between the sliding sleeve 6 and the feed pipe 4, and the sealing cloth 7 is elastic; a driving component, which is arranged on the feed pipe 4, and is used to control the connection relationship between the feed pipe 4 and the outside.

[0024] In the above scheme, the support frame 1 is made of stainless steel, which has strong corrosion resistance and high structural strength. The storage cylinder 2 is made of materials with excellent anti-static performance and impact resistance. For example, high-density polyethylene (HDPE) with conductive materials added 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 a faucet structure, which allows the material in the storage cylinder 2 to flow outward. The top of the storage cylinder 2 is provided with a groove, and the feed pipe 4 is located inside the groove. The sealing cloth 7 is made of silicone, which has good sealing and elasticity, and is chemically inert and not easy to react with other chemicals. In the initial state, the sliding sleeve 6 is located at the upper part of the feed pipe 4, so that the sealing cloth 7 maintains a torsional deformation state. The cross-section of the sealing cloth 7 is n-shaped. By fixing one end of the sealing cloth 7 and rotating the other end of the sealing cloth 7, the middle part of the sealing cloth 7 is twisted and entangled to a point (the existing structure is similar to a twist cup), so that the sealing cloth 7 is in a blocked state for the feed pipe 4. When the storage cylinder 2 is filled, the liquid outlet pipe of the filling machine is connected to the feed pipe 4 to form a sealed filling environment. At the same time, the sealing cloth 7 is released from the feed pipe 4 to prevent external impurities from entering the storage cylinder 2 when it is filled, affecting the purity of the subsequent liquid.

[0025] Specifically, Figure 5 and Figure 6 As shown, the driving assembly includes: a first elastic member 201, which is arranged between the feed pipe 4 and the sliding sleeve 6, and an inclined slide groove 202 is arranged outside the feed pipe 4; a clamping block 203, which is fixedly connected to the sliding sleeve 6, and the clamping block 203 is located in the inclined slide groove 202 and slides.

[0026] In the above scheme, the first elastic member 201 is a spring and is initially in a compressed state, and is used to apply a stable upward thrust to the sliding sleeve 6, that is, when not subject to external force, the sliding sleeve 6 is stabilized on the upper part of the feed pipe 4, thereby improving the stability of the sealing of the feed pipe 4 by the sealing cloth 7. The number of inclined grooves 202 can be freely set according to actual conditions, and are distributed on the outer wall of the feed pipe 4 at equal intervals in the circumferential direction. The number of blocks 203 is the same as the number of inclined grooves 202. The blocks 203 slide along adjacent inclined grooves 202, causing the sliding sleeve 6 to twist, thereby causing the sealing cloth 7 to twist and deform, thereby releasing the sealing of the feed pipe 4 by the sealing cloth 7.

[0027] Working principle: when it is necessary to fill liquid into the storage cylinder 2, it is necessary to unscrew the sealing cap 5 in advance to separate the sealing cap 5 from the storage cylinder 2, and then place the device in the filling position, and start the filling operation of the device through the filling machine. At this time, since the sealing cloth 7 is in a torsional deformation state, that is, the sealing cloth 7 is in a blocking state for the feed pipe 4, impurities in the outside air cannot enter the storage cylinder 2, and the liquid outlet pipe of the filling machine moves downward to contact 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, and the sliding sleeve 6 moves downward to drive a number of card blocks 203 uniformly distributed on it in the circumferential direction to move synchronously. The card blocks 203 slide along the adjacent inclined slide grooves 202, so that the sliding sleeve 6 moves downward along the feed pipe 4 and rotates at the same time, and the sliding sleeve 6 drives the sealing cloth 7 to twist synchronously, and the sealing cloth 7 is released from the twisted state, so that the liquid outlet pipe of the filling machine is connected with the feed pipe 4, and then the filling machine is turned on to start the filling operation, and so on until the filling is completed.

[0028] When 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 squeezing of the sliding sleeve 6. At this time, the first elastic member 201 drives the sliding sleeve 6 to move upward synchronously, and the block 203 resets and slides along the adjacent inclined slide groove 202, so that the sliding sleeve 6 resets and rotates, and so on until the sliding sleeve 6 is reset to the initial position, so that the sealing cloth 7 is twisted to form a seal against the feed pipe 4 again, and then the cover 5 is twisted onto the storage cylinder 2. When the device needs to be filled again, the above steps are repeated. Before the storage cylinder 2 is filled, the feeding pipe 4 is blocked by the sealing cloth 7, and when the storage cylinder 2 is filled, the liquid outlet pipe of the filling machine is connected and fitted with the feeding pipe 4 to form a sealed filling environment, and the sealing cloth 7 is released to block the feeding pipe 4, thereby reducing the probability of external impurities entering the storage cylinder 2 during filling, thereby improving the purity of the liquid.

[0029] After the filling is completed in this application, it is often necessary to carry out vehicle transportation operations. During the vehicle transportation process, the device will inevitably vibrate due to bumps, resulting in a weakened joint seal between the cover 5 and the storage cylinder 2, reducing the sealing strength, causing external water vapor to enter the storage cylinder 2. At this time, the cover 5 is docked with the storage cylinder 2, so that the cover 5 and the grooves of the storage cylinder 2 jointly form an enveloping seal for the feed pipe 4, and then the sealing cloth 7 forms a seal on the inside of the feed pipe 4. At this time, the feed pipe 4 is doubly sealed by the cover 5 and the sealing cloth 7, which greatly improves the sealing strength of the storage cylinder 2 and reduces the probability of external water vapor entering the storage cylinder 2 and causing contamination.

[0030] In a further embodiment, Figure 2-Figure 4 As shown, the feed pipe 4 is slidably connected to the storage barrel 2, a plurality of circumferentially distributed second elastic members 301 are arranged between the feed pipe 4 and the storage barrel 2, the feed pipe 4 and the storage barrel 2 are fixedly connected and connected with a flexible ring 302; the sliding sleeve 6 is provided with an inclined annular surface 303; the feed pipe 4 is fixedly connected with a locking ring 304, the storage barrel 2 is slidably connected with an extrusion frame 305, the extrusion frame 305 is used to extrude the limiting locking ring 304, and the cover 5 is used to limit the extrusion frame 305; a third elastic member 306 is arranged between the storage barrel 2 and the extrusion frame 305.

[0031] In the above scheme, the second elastic member 301 is a spring, the number of the second elastic members 301 can be freely set, and a plurality of second elastic members 301 are circumferentially evenly spaced and distributed between the feed tube 4 and the storage cylinder 2, and are used to drive the feed tube 4 to reset. The material of the flexible ring 302 is silicone, which can adapt to the position change of the feed tube 4. The inclined annular surface 303 on the sliding sleeve 6 faces the central axis of the feed tube 4. The injection pipe of the external filling machine contacts the inclined annular surface 303 on the sliding sleeve 6, so that the injection pipe of the filling machine drives the feed tube 4 to move through the sliding sleeve 6. The locking ring 304 is set There is an annular inclined surface, and the extrusion frame 305 is provided with an inclined surface that fits with the annular inclined surface on the locking ring 304. The extrusion frame 305 squeezes the locking ring 304 through the inclined surface to lock the position of the feeding tube 4. The third elastic member 306 is a spring, and is in a compressed state in the initial state. It is used to push the extrusion frame 305 to move upward and separate from the annular inclined surface of the locking ring 304, release the extrusion state of the locking ring 304, and make the position of the feeding tube 4 automatically follow the change of the liquid outlet pipe of the filling machine, so that the central axes of the two coincide, ensuring smooth flow of liquid.

[0032] When the device is performing a filling operation, the device is usually transported to the bottom of the filling machine through a conveyor belt. The vibration of the conveyor belt will change the position of the device, resulting in the central axis of the filling machine's liquid outlet pipe and the central axis of the filling port being unable to be aligned, causing the liquid flow of the device to be unsmooth during filling.

[0033] Working principle: During the filling process of the device, when the cover 5 is separated from the storage tube 2, the cover 5 releases the extrusion on the extrusion frame 305, the third elastic member 306 extends from the compressed state, and pushes the extrusion frame 305 to slide upward along the storage tube 2. At the same time, the extrusion frame 305 releases the extrusion limit on the locking ring 304, so that the feed tube 4 is converted into a free sliding state.

[0034] After the feed pipe 4 is converted into a 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 annular surface 303 on the sliding sleeve 6, and squeezes the sliding sleeve 6 through the inclined annular surface 303, so that the sliding sleeve 6 generates a horizontal movement force, and 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 until the central axis of the feed pipe 4 coincides with the central axis of the liquid outlet pipe of the filling machine. At this time, the feed pipe 4 stops horizontal movement, and the flexible ring 302 is deformed to adapt to the position change of the feed pipe 4 to ensure smooth injection of the liquid. By making the position of the feed pipe 4 automatically follow the change of the liquid outlet pipe of the filling machine, the central axes of the two coincide, ensuring smooth flow of the liquid.

[0035] When the filling of the device is completed, that is, when the filling machine drives the liquid outlet pipe to move upward, the extrusion on the sliding sleeve 6 is released. At this time, the deformed second elastic member 301 is reset to push the feed pipe 4 to reset to the initial state, and the flexible ring 302 is restored to the initial state, and then the cover 5 is twisted into the storage cylinder 2 again. At this time, the cover 5 presses down the extrusion frame 305, and at the same time the third elastic member 306 is compressed, so that the extrusion frame 305 squeezes the locking ring 304 and locks it. At this time, the cover 5 is twisted. When the above problem occurs again, repeat the above steps.

[0036] In a further embodiment, Figure 4-Figure 7 As shown, the sliding sleeve 6 is fixedly connected with a sealing airbag 401, which is wrapped by a sealing cloth 7 and fits the feeding pipe 4; the feeding pipe 4 is fixedly connected with an annular shell 402, the sliding sleeve 6 is fixedly connected with a pushing ring 403, the annular shell 402 and the pushing ring 403 are sealingly and slidingly connected, the sealing airbag 401 and the annular shell 402 are fixedly connected and connected with a connecting hose 404, the connecting hose 404 passes through the sliding sleeve 6, and the annular shell 402 is provided with a plurality of pressure holes 405, and the pressure holes 405 are used to reduce the sliding resistance of the pushing ring 403; the connecting hose 404 is elastic, and the connecting hose 404 has a length margin, so that it is always in a loose state to adapt to the position change of the sliding sleeve 6; the elastic coefficient of the sealing cloth 7 is greater than the elastic coefficient of the connecting hose 404, so that the connecting hose 404 can store gas.

[0037] In the above scheme, the sealing airbag 401 is made of polyethylene, which is easy to customize and process, and has good sealing performance, durability and chemical corrosion resistance. The sealing airbag 401 is located on the upper side of the sliding sleeve 6, and the push ring 403 is located on the lower side of the sliding sleeve 6. The material of the connecting hose 404 is silicone. The number of pressure holes 405 on the annular shell 402 can be freely set, and they are evenly spaced and distributed on the upper side of the annular shell 402 to reduce the sliding resistance of the push ring 403. The connecting hose 404 has enough length to adapt to the position change of the sliding sleeve 6 to avoid unnecessary stretching of the connecting hose 404 and reduce the connecting hose. The service life of 404 is extended by driving the sealing cloth 7 to fit the bottom of the liquid injection tube of the filling machine through the sealing airbag 401, thereby reducing the probability of liquid leakage and further straightening the sealing cloth 7 so that the sealing cloth 7 fits the inner wall of the feed tube 4 to ensure the smoothness of liquid injection. The elastic coefficient of the sealing cloth 7 is greater than the elastic coefficient of the connecting hose 404, that is, after the sealing cloth 7 is stretched to the limit state, it cannot continue to be stretched by the expansion force of the sealing airbag 401, and the remaining gas will be stored in a number of connecting hoses 404 for subsequent filling of the sealing airbag 401, ensuring that the sealing airbag 401 is always in close contact with the sealing cloth 7 to keep the sealing cloth 7 in a straightened state.

[0038] When the device is performing the filling operation, the lower side of the filling pipe of the filling machine becomes uneven due to corrosion and aging after long-term use, resulting in a gap between the filling pipe of the filling machine and the filling port after they are connected, causing liquid leakage during the filling process.

[0039] 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 push ring 403 at the bottom to move synchronously, so that the push ring 403 slides downward along the annular shell 402, and the gas in the annular shell 402 enters the sealing airbag 401 along the connecting hose 404 distributed at equal intervals in the circumferential direction, and 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 be gradually tightened, so that the sealing cloth 7 fits the inner wall of the feeding pipe 4, until the sliding sleeve 6 stops moving downward, and the push ring 403 is driven downward by the sliding sleeve 6, 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, thereby reducing the probability of liquid leakage, and at the same time further straightens the sealing cloth 7, so that the sealing cloth 7 fits the inner wall of the feeding pipe 4, to ensure the smoothness of liquid injection.

[0040] After long-term use, the sealing cloth 7 will be stretched due to continuous twisting and release, which makes it impossible for the sealing cloth 7 to fit tightly against the inner wall of the feed tube 4, thereby affecting the smooth injection of the 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 along the several connecting hoses 404, the sealing airbag 401 is limited by the sealing cloth 7 and cannot continue to expand. At this time, the remaining gas will be stored in the several connecting hoses 404 and cause the connecting hoses 404 to expand. If the sealing cloth 7 is stretched, the sealing cloth 7 releases the limitation 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 further expand, so that the sealing airbag 401 will straighten the sealing cloth 7 again, thereby improving the fluidity of the liquid.

[0041] When the filling of the device is completed, that is, the sliding sleeve 6 moves upward to return to the initial state, the sliding sleeve 6 drives the push ring 403 to return upward synchronously, so that the gas in the sealing airbag 401 and the connecting hose 404 returns to flow into the annular shell 402. When the device needs to be filled again, the above steps are repeated.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
