Summary of the invention

[0003] The purpose of the present invention is to provide a flexible oil supply bag storage and transportation system. The present invention utilizes the product's double bag structure to simultaneously store two different liquids within a limited storage space, and simultaneously realizes two oil delivery methods: one is oil pump delivery, and the other is oil delivery by squeezing the inner bag.

[0004] The objective of the present invention is achieved through the following technical solutions: A flexible oil supply bladder storage and transportation system comprises a pressure-bearing device, an oil pipeline, an inflation pipeline, a porous groove infusion pipe, a grooved rubber part, a connector and a rubber bladder body. The pressure-bearing device of the system is installed with the rubber bladder body inside the pressure-bearing device by welding or screws; the oil pipeline is connected to a blind plate by threading; the inflation pipeline is connected to the pressure-bearing device and the outer bladder of the rubber bladder by threading; the porous groove infusion pipe is connected to the blind plates at the head and tail ends of the rubber bladder body by threading; the grooved rubber part is bonded to the bottom surface of the rubber bladder body; its inner connector and outer connector are connected to the outer bladder; the oil pipeline is connected to the blind plate by threading, and a switch valve is installed at one end of the oil pipeline; the inflation pipeline is connected to the pressure-bearing device and the outer bladder of the rubber bladder by threading; the porous groove infusion pipe is connected to the blind plates at the head and tail ends of the rubber bladder body by threading; the rubber bladder body is composed of an outer bladder and an inner bladder, and the inner bladder is connected to the head and tail of the outer bladder respectively with the head and tail of the inner bladder by a rubber flange inside the outer bladder.

[0005] The flexible oil supply bag storage and delivery system, the pressure bearing device is a sealing structure, and the head section is provided with a mounting hole.

[0008] The advantages and effects of the present invention are: 1. In the limited space of the present invention, as the fuel in the inner bag decreases, another medium can be stored in the space between the outer bag and the inner bag, thereby improving the space utilization rate. The porous groove infusion pipe and the grooved rubber parts in the system can ensure the smooth output of the fuel in the inner bag on the one hand; on the other hand, it can improve the output rate of the fuel in the inner bag and improve its utilization rate. The fuel in the inner bag can be output in two ways. One is to use the inflation extrusion method, in which the space between the outer bag and the inner bag is inflated through the inflation pipeline to generate a certain pressure to squeeze the inner bag, so as to output the fuel in the inner bag; the other is to use the oil pump method, connect the oil pump at the end of the oil pipeline, and output the fuel in the inner bag through the oil pump.

The double-bladder structure of the present invention can store two different liquid media at the same time; the system has two oil delivery methods, and the appropriate oil delivery method can be selected according to the use environment. The outer bladder in the system plays a sealing role, which can reduce the technical requirements for the sealing of the pressure-bearing device and reduce costs.

[0010] 3. The present invention adopts inflation extrusion oil delivery, which can be divided into two usage modes. One is when there are index requirements for the output flow rate, the space between the outer bag and the inner bag needs to be filled with high-pressure gas, and this system mode needs to be adopted. The other is when there is no requirement for the output flow rate, the pressure-bearing device is not required, and the outer bag plays a role of pressure bearing and sealing.

[0013] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings.

[0015] The present invention discloses a flexible oil supply bladder storage and transportation system, comprising a pressure-bearing device, an oil pipeline, an air-charging pipeline, a porous groove infusion pipe, a grooved rubber part and a rubber bladder body. The pressure-bearing device is a hard steel structure system, which is installed on the outside of the rubber bladder body. The oil pipeline is connected to the rubber bladder body through screws and a blind plate, and the other end is connected to the oil pump, and a switch valve is installed on the oil pipeline. The air-charging pipeline is connected to the rubber bladder body through screws, and the other end is connected to the inflation gas source, and an opening valve is installed on the air-charging pipeline. The porous groove infusion pipe is connected to the blind plate through threads and fixed inside the rubber bladder body. The grooved rubber part is adhered to the bottom surface of the rubber bladder body by means of adhesive bonding. The rubber bladder body is divided into an outer bladder and an inner bladder, and the outer bladder and the inner bladder are fixed together at both ends by a rubber flange.

[0016] The pressure-bearing device 13 is a sealing structure, and a mounting hole 14 is reserved in the head section. The oil pipeline 6 is connected to the blind plate 4 by means of threads, and the switch valve 12 is installed at one end of the oil pipeline. The inflation pipeline 5 is connected to the pressure-bearing device 13 and the outer bladder 1 of the rubber bladder by means of threads. The porous groove infusion tube 7 is connected to the blind plates 4 at the head and tail ends of the rubber bladder body by means of threads. The grooved rubber part 8 is pasted on the bottom of the inner surface of the inner bladder 2. The inner connecting part 9 and the outer connecting part 10 are connected to the outer surface of the outer bladder 1, and then connected to the inner surface of the pressure-bearing device 13. The rubber bladder body is composed of an outer bladder 1 and an inner bladder 2. The inner bladder 2 is inside the outer bladder 1, and the head and tail of the outer bladder 1 are respectively connected to the head and tail of the inner bladder 2 by means of a rubber flange 3.

[0017] The outer bag is used as a sealing structure for storing gas. The rubber-coated fabric with a two-rubber-one-cloth structure is used. The vulcanized rubber-coated fabric is cut into samples of certain specifications, the bonding part is hemp-beaten, and the sealing structure of a certain shape is formed by glue bonding, and then vulcanized and formed by tank-type or press-pressing method.

[0018] The inner bladder is used as a sealing structure for storing liquid oil. The rubber-coated fabric with a two-rubber-one-cloth structure is used. The rubber layer in contact with the medium oil is made of oil-resistant rubber-plastic alloy as the main body. The vulcanized rubber-coated fabric is cut into samples of certain specifications, the bonding part is hemp-beaten, and the sealing structure of a certain shape is formed by glue bonding, and then vulcanized and formed by tank vulcanization or laminating machine laminating.

[0019] The rubber flange is used as a transition structure between the rubber bladder and the blind plate. It adopts a rubber-metal structure and is formed by compression molding. When bonding with the rubber bladder, the bonding position of the rubber flange and the bonding position of the rubber bladder need to be hemped, and the bladder is connected by glue bonding, and then vulcanized by tank or press pressing.

[0020] The blind plate is used as a sealing structure at both ends of the rubber bladder. The blind plate is made of stainless steel and connected to the rubber flange by bolts.

[0021] The inflation pipeline is made of stainless steel, connected to the pressure-bearing device and the rubber bladder with a flange clamping structure, and the end is connected to the inflation valve.

[0022] The oil pipeline is made of stainless steel, one end of which is connected to the blind plate of the rubber bladder through a thread, and the other end is connected to the oil delivery valve.

[0023] The porous groove infusion tube is made of stainless steel, with a hollow tube structure, internal threads at both ends, longitudinal infusion grooves and circumferential infusion grooves on the outside of the tube body, and the infusion holes penetrate the tube wall from outside to inside. The internal threads at both ends of the tube body are connected and fixed with blind plates, and the porous groove liquid delivery tube penetrates the inside of the rubber bladder. The liquid flows into the cavity of the tube body through the infusion groove and the infusion hole, and then is discharged through the infusion tube.

[0024] The grooved rubber part is made of rubber and is molded. One side has longitudinal and transverse grooves, which are oriented toward the inside of the rubber bladder; the other side is a flat structure, which is bonded to the bottom of the inner bladder by glue after being hemped. As the amount of oil inside the bladder decreases, the bladder becomes concave, causing the bladder tape to fit together, which causes the oil to not flow smoothly inside the bladder; when the bladder tape fits together, the grooved molded part will leave space between the fitting tapes, and the oil will flow into the bottom of the bladder through the grooves of the grooved molded part, and then flow into the porous groove oil pipeline, and flow out through the oil pipeline.

[0025] The connector is a composite structure of a rubber-coated fabric wrapped with a rubber stick of 13-16mm in diameter, which is used to fix the bladder and the pressure-bearing device. The inflatable switch valve is a stainless steel ball valve structure. The oil pipeline switch valve is a stainless steel ball valve structure. The pressure-bearing device is made of stainless steel or other hard materials and has a certain rigidity. Due to the limitation of the ultimate pressure of the rubber-coated fabric used in the rubber bladder, a pressure-bearing device is added to the outside of the entire rubber bladder to ensure that the rubber bladder can ensure the normal operation of the system in the overpressure condition.

[0026] The mounting hole is a circular hole with a diameter of 600-700. The rubber bladder is transported to the inside of the pressure-bearing device through the hole. After the rubber bladder is installed and connected with the pressure-bearing device, the mounting hole is sealed. The air source is a compressed air device, which can be a gas cylinder or an air compressor.

[0027] The oil delivery pump is an output device for the fuel in the inner bladder. The oil delivery pipe is made of stainless steel and is connected to the oil delivery pump.

[0028] When the invention is working, the pressure bearing device is first fixed at a designated position, and then the rubber bladder and other supporting equipment are installed through the installation hole. When in use, the air in the bladder is first evacuated to a vacuum state, and then fuel oil is injected into the inner bladder through the oil delivery port for standby use.

[0029] There are two ways to use the fuel oil in the inner bladder: one is to output the fuel oil through the oil pump. The other is to inject gas into the space between the outer bladder and the inner bladder through the inflation pipeline. When the stored gas reaches a certain pressure, the inner bladder can be squeezed to discharge the fuel oil.

[0030] The present invention realizes the storage of multiple media in a limited storage space. For example, the outer capsule is made of a hard material or a soft material, and the inner capsule is made of a soft material. The inner capsule stores liquid fuel to provide fuel for the equipment. As the liquid fuel in the inner capsule decreases, there is surplus space in the limited storage space, and the space between the outer capsule and the inner capsule can store another liquid. The double-layer structure of the outer capsule and the inner capsule is used to fill the space between the outer capsule and the inner capsule with water through the inflation pipeline of the outer capsule, and the liquid output is achieved by squeezing the inner capsule.

[0031] When the soft product storing liquid deteriorates with the decrease of internal liquid, the outer wall of the soft product will be deformed inward to form a "gourd" shape, and a sealed space will be formed. Due to the presence of the porous groove liquid infusion pipe, the sealed space is connected by the porous groove liquid infusion pipe, and the liquid can flow to the product oil infusion port through the porous groove liquid infusion pipe. Even if the outer wall of the product wraps around the porous groove liquid infusion pipe, due to the infusion groove on the tube wall, the liquid will flow into the infusion hole through the infusion groove, and then flow into the tube body cavity through the infusion hole, thereby discharging the liquid.
