Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a pneumatic pumping device, in particular to a pneumatic pumping device using pulse air delivery. Background Art

[0002] Pumping device generally refers to pump, which is mainly used to transport fluid or pressurize fluid, transfer the mechanical energy of the prime mover or other external energy to the liquid, so as to increase the energy of the liquid. For example, liquids such as water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal can also be transported, of course, liquid and gas mixtures and liquids containing suspended solids.

[0003] The application of pumps is indispensable in industrial production. According to the needs of different fields and occasions, there are many types of pumps, generally water-type, rotary type, centrifugal type, volumetric or diaphragm type, etc. Most of the existing pumps still use stainless steel and carbon steel as the main pump body materials. Of course, there are also some pump structures made of new materials, such as inorganic non-metallic materials ceramics, fiberglass, graphite and carbon products, and synthetic organic polymer materials such as plastics, glass fiber or carbon fiber reinforced engineering plastics.

[0004] However, these pumps are actually mostly used in industrial production. They are relatively large in size, not suitable for carrying, and inconvenient to use in daily production and life. In addition, when conveying fluids and other media, the existing pump suction devices often convey continuously when in the open state, which cannot meet the requirements for short-term intermittent conveying in specific fields.

[0005] In summary, in order to solve the structural deficiencies of the existing pumping device, the present invention designs a pneumatic pumping device with a reasonable structure and convenient use. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a pneumatic pump suction device which has a reasonable structure and is convenient to use.

[0007] The purpose of the present invention can be achieved through the following technical solutions: A pneumatic pumping device, comprising:

[0008] The outer shell is rigidly arranged, and an air inlet pipe and an air outlet pipe for conveying pulse air are provided at the upper and lower ends of the outer shell;

[0009] The inner shell is flexibly arranged, the inner shell is located inside the outer shell and encloses the outer shell to form an air cavity, the air inlet pipe and the air outlet pipe are respectively connected to the air cavity, the upper and lower ends of the inner shell are penetrated by an input pipe and an output pipe for conveying the medium, and the input pipe and the output pipe are respectively arranged to penetrate the outer shell outward;

[0010] The viscous layer is provided with two viscous layers, which are located in the air cavity and arranged on both sides of the inner shell. When the pulse air enters the air cavity from the air inlet pipe and is further output from the air outlet pipe, the inner shell undergoes wave-like deformation under the action of the viscous layer. After the medium enters the inner shell from the input pipe, it flows intermittently and is further transported outward by the output pipe.

[0011] As a further improvement of the present case, the shell has two symmetrically arranged curved walls, the upper and lower ends of the two curved walls are sealed and connected through the top surface and the bottom surface respectively, and the above-mentioned air inlet pipe and air outlet pipe pass through the top surface and the bottom surface respectively.

[0012] As another improvement of the present case, the inner shell is formed by two curved surfaces fitting each other, and the two curved surfaces enclose a medium cavity. The above-mentioned input pipe and output pipe are respectively connected to the medium cavity, and the input pipe is arranged to pass through the top surface outwardly, and the output pipe is arranged to pass through the bottom surface outwardly.

[0013] As a further improvement of the present invention, the two curved walls are arranged corresponding to the two curved surfaces, and each curved wall is sealed and fitted with an edge on the same side of each curved surface.

[0014] As a further improvement of the present case, each adhesive layer is located between the corresponding curved surface and the curved wall, and the upper and lower ends of the adhesive layer are respectively fixedly connected to the top surface and the bottom surface.

[0015] As a further improvement of the present invention, the cross sections of the outer shell and the inner shell are both shuttle-shaped.

[0016] Compared with the prior art, the present invention has a reasonable structural arrangement. By coordinating the viscous layer and the flexible inner shell and introducing pulsed air into the air cavity, the flexible inner shell undergoes a wave-like deformation and the internal space of the inner shell undergoes regular changes, which is conducive to the intermittent flow and transportation of the medium in the inner shell and has a good use effect.

[0023] The technical solution of the present invention is further described below in conjunction with the embodiments and drawings.

[0024] like Figures 1 to 5 As shown, the pneumatic pumping device comprises:

[0025] The housing 10 is rigidly arranged, and an air inlet pipe 11 and an air outlet pipe 12 for conveying pulse air are provided at the upper and lower ends of the housing 10;

[0026] The inner shell 20 is flexibly arranged. The inner shell 20 is located inside the outer shell 10 and encloses the outer shell 10 to form an air cavity 40. The air inlet pipe 11 and the air outlet pipe 12 are respectively connected to the air cavity 40. The upper and lower ends of the inner shell 20 are provided with an input pipe 21 and an output pipe 22 for conveying the medium, and the input pipe 21 and the output pipe 22 are respectively arranged to penetrate the outer shell 10 outwards.

[0027] The viscous layer 30 is provided with two viscous layers 30, which are located in the air cavity 40 and arranged on both sides of the inner shell 20. When the pulse air enters the air cavity 40 from the air inlet pipe 11 and is further output from the air outlet pipe 12, the inner shell 20 undergoes wave-like deformation under the action of the viscous layer 30, and the medium enters the inner shell 20 from the input pipe 21 and flows intermittently, and is further transported outward by the output pipe 22.

[0028] Pumps are actually mostly used in industrial production. They are relatively large in size, not suitable for carrying, and inconvenient to use in daily production and life. In addition, when existing pump suction devices transport fluids and other media, they often transport continuously when in the open state, which cannot meet the requirements for short-term intermittent transportation in specific fields.

[0029] To this end, the present invention provides a pneumatic pumping device, which cooperates with the viscous layer 30 and the flexible inner shell 20, and simultaneously introduces pulsed air into the air cavity 40, so that the flexible inner shell 20 undergoes wave-like deformation, and the internal space of the inner shell 20 undergoes regular changes, which is conducive to the intermittent flow and transportation of the medium in the inner shell 20, and the use effect is good.

[0030] Specifically, in the present embodiment, a double-layer structure of an inner shell 20 and an outer shell 10 is preferably provided, wherein the outer shell 10 is a rigid structure and the inner shell 20 is a flexible structure, and the pressure in the air cavity 40 is changed by inputting pulse air into the air cavity 40 between the inner shell 20 and the outer shell 10, wherein the flexible inner shell 20 is deformed under the pressure change, thereby changing the volume of the internal space of the inner shell 20.

[0031] When the pulse air enters the air cavity 40, the positive pressure makes the inner shell 20 move away from the outer shell 10, and the negative pressure makes the inner shell 20 move closer to the outer shell 10. Due to the setting of the viscous layer 30, the inner shell 20 continuously repeats the process of approaching or moving away from the outer shell 10, showing a wave-like regular deformation. At this time, the internal space of the inner shell 20 continuously transports the medium in a "bubble" state, forming a form similar to "swallowing", thereby realizing intermittent transportation of the medium, facilitating better control of the flow and transportation of the medium, and having a good use effect.

[0032] like Figure 1 and Figure 2 As shown, preferably, the housing 10 has two symmetrically arranged curved walls 15, the upper and lower ends of the two curved walls 15 are sealedly connected through the top surface 13 and the bottom surface 14 respectively, and the above-mentioned inlet pipe 11 and outlet pipe 12 pass through the top surface 13 and the bottom surface 14 respectively.

[0033] In this embodiment, the housing 10 is preferably composed of a top surface 13, a bottom surface 14 and two curved walls 15. The top surface 13 is sealed and fitted with the top edges of the two curved walls 15, the bottom surface 14 is sealed and fitted with the bottom edges of the two curved walls 15, and the sides of the two curved walls 15 are sealed and fitted, and the entire housing 10 is arranged in a square bag shape. The air inlet pipe 11 is arranged through the top surface 13, and the air outlet pipe 12 is arranged through the bottom surface 14, and then communicates with the air cavity 40, which is convenient for the input and output of pulse air.

[0034] like Figures 3 to 5 As shown, further, the inner shell 20 is formed by two curved surfaces 23 fitting together, and the two curved surfaces 23 enclose a medium cavity 50. The input pipe 21 and the output pipe 22 are respectively connected to the medium cavity 50, and the input pipe 21 is arranged to pass through the top surface 13 outwardly, and the output pipe 22 is arranged to pass through the bottom surface 14 outwardly.

[0035] In this embodiment, the inner shell 20 is preferably formed by sealing and laminating the edges of the two curved surfaces 23, forming a medium cavity 50 inside, and the edges of the upper and lower ends of the curved surface 23 bypass the input tube 21 and the output tube 22 for sealing and laminating, and at the same time, the edges of the curved surface 23 are sealed and connected with the corresponding input tube 21 or output tube 22 to ensure that the medium cavity 50 is completely isolated from the air cavity 40. Here, the input tube 21 and the output tube 22 pass through the corresponding top surface 13 and the bottom surface 14 outward to facilitate the input of the medium.

[0036] Preferably, the two curved walls 15 are disposed correspondingly to the two curved surfaces 23 , and each curved wall 15 is sealed and fitted with an edge on the same side of each curved surface 23 .

[0037] The two curved surfaces 23 are located between the two curved walls 15, and the sides of the curved surfaces 23 are arranged corresponding to the sides of the curved walls 15. In this embodiment, the curved surfaces 23 are preferably arranged to be sealed and fitted with the edges of the corresponding sides on the curved walls 15, and the outer shell 10 and the inner shell 20 are connected together on both sides to ensure the stability of the overall structure. In addition, the cross-sections of the outer shell 10 and the inner shell 20 are both arranged in a shuttle shape, and the outer shell 10 visually presents a square bag-like structure from the outside, and the overall structure is compact, small in size, and easy to carry.

[0038] Furthermore, each adhesive layer 30 is located between the corresponding curved surface 23 and the curved wall 15 , and the upper and lower ends of the adhesive layer 30 are respectively fixedly connected to the top surface 13 and the bottom surface 14 .

[0039] The viscous layer 30 is actually located between the curved surface 23 and the curved wall 15. The upper and lower ends of the viscous layer 30 are fixedly connected to the top surface 13 and the bottom surface 14. Under the action of the viscous layer 30, when the pulse air enters the air cavity 40, the deformation of the inner shell 20 is actually manifested as a symmetrical wave-like deformation formed by the two curved surfaces 23, and then a row of "bubble" structures are formed between the two curved surfaces 23, which is convenient for intermittent transmission of the medium. Under the interaction of forces, the viscous layer 30 will also deform accordingly.

[0040] It is worth mentioning that in actual operation, the viscous layer 30 can also be a coating applied on the inner wall of the outer shell 10 or the outer wall of the inner shell 20, and of course, it can also be applied on the opposite sides of the inner shell 20 and the outer shell 10, so that the inner shell 20 and the outer shell 10 are mutually adhered. The viscosity of the viscous layer 30 does not need to be too high. When the pulse air is introduced, it can drive the inner shell 20 to deform, and a kind of almost non-existent viscosity between the inner shell 20 and the outer shell 10 is sufficient.

[0041] In this embodiment, the inner shell 20 and the outer shell 10 are sealed and attached by using adhesive and heat sealing technology, which is convenient for manufacturing. The pumping device can be used as an air pumping supply device, which can provide low pressure and low flow rate, and can be used in cooling vests, or replace electric liquid pumps, air pumps, etc. in certain fields or occasions; in addition, it can also be used for mixing and dispensing beverages, or for measuring the liquid discharge rate of patients in hospitals.

[0042] The pneumatic pump suction device has a reasonable structure. Through the coordinated arrangement of the viscous layer 30 and the flexible inner shell 20, pulsed air is introduced into the air cavity 40 at the same time, so that the flexible inner shell 20 undergoes wave-like deformation, and the internal space of the inner shell 20 undergoes regular changes, which is conducive to the intermittent flow and transportation of the medium in the inner shell 20, and the use effect is good.

[0043] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto. Any modification or supplement or replacement of the specific embodiments described by those skilled in the art shall be included in the protection scope of the present invention.
