Description

Technical Field

[0001] The invention relates to the technical field of vortex tubes, and in particular to an energy-saving double-sided high-efficiency vortex tube heater. Background Art

[0002] A vortex tube heater is a device that separates gas into cold and hot air streams through a specific structure and uses the hot air stream for heating. The working principle of a vortex tube heater is to use the vortex effect to separate compressed gas (usually air) into cold and hot air streams. The hot air stream is used to heat the target object or space, while the cold air stream is usually discharged or used for other purposes.

[0003] At present, the air inlet of the existing vortex tube heater is usually set to a normally open state. Even when there is no heating demand, gas may continue to enter the vortex tube heater and be separated into cold and hot air flows. This will not only lead to unnecessary energy consumption and fail to achieve energy-saving effects, but may also reduce the overall energy of the vortex tube heater. Secondly, the normally open setting of the air inlet may cause failures or risks due to external factors (such as dust, moisture, etc.). In view of this, the present invention is specially proposed.

Under the action of centrifugal force, it is divided into an outer cold air flow and an inner hot air flow. In the process of the outer cold air flow flowing along the tube wall to the exhaust pipe 2, its internal energy is gradually converted into kinetic energy, resulting in a drop in temperature; while the inner hot air flow flows toward the other end, and its temperature will rise.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Embodiment 1:

[0038] Reference Figure 1-Figure 10 An energy-saving double-sided high-efficiency vortex tube heater comprises a metal outer tube 1, and an exhaust pipe 101 and an exhaust pipe 2 102 arranged at both ends of the metal outer tube 1, and further comprises: a sleeve 103 sleeved on the metal outer tube 1, a fixing sleeve 104 is arranged on the sleeve 103, an air inlet pipe 2 is arranged on the metal outer tube 1, and the fixing sleeve 104 is sleeved on the outer wall of the air inlet pipe 2; a fixing ring 3 is also provided, and a connecting pipe 301 is provided between the fixing ring 3 and the inner wall of the metal outer tube 1; a baffle 303 is rotatably provided at the bottom of the fixing ring 3, and four baffles 303 are provided, and rubber pads 304 are respectively provided on the outer walls of the four baffles 303, and the rubber pads 304 on the four baffles 303 are fitted together; an inclined plate 4 is rotatably provided inside the metal outer tube 1.

[0039] In this embodiment, in the initial state, the rubber pads 304 on the four baffles 303 fit together, so that the four baffles 303 can block the intake pipe 2, so that the intake pipe 2 is in a closed state, which can avoid unnecessary flow of gas when there is no heating demand, thereby reducing energy waste, achieving efficient utilization of energy, and achieving energy saving effects. Secondly, the four baffles 303 block the intake pipe 2, which can prevent dust, moisture, etc. from entering the vortex tube, thereby causing damage to the vortex tube heater, thereby ensuring its service life. The vortex tube heater uses the high-speed rotation of the compressed gas to generate vortexes, so that heat is generated inside the heated object, and then the heated gas is discharged through the exhaust pipe 1 101, and the cold air can be discharged through the exhaust pipe 2 102. The heating method is highly efficient, reduces energy loss during heat conduction, and improves energy saving effects.

[0040] When in use, a pipeline for conveying gas is connected to the air inlet pipe 2, so as to drive the four baffles 303 to rotate, so that the gas can pass through the middle of the four baffles 303, and then the gas will pass through the inclined plate 4 and enter the interior of the metal outer tube 1, and then generate vortex through high-speed rotation. Under the action of centrifugal force, these gases are divided into an outer layer of cold air flow and an inner layer of hot air flow. In the process of the outer layer of cold air flow flowing along the pipe wall to the exhaust pipe 2 102, its internal energy is gradually converted into kinetic energy, causing the temperature to drop, and then it can be discharged from the exhaust pipe 2 102; while the inner layer of hot air flow flows toward the other end, its temperature will rise, and then it will be discharged from the exhaust pipe 1 101.

[0041] An annular plate 111 is provided on the inner wall of the metal outer cylinder 1 . A frustum 109 is also provided on the inner wall of the metal outer cylinder 1 . A plurality of oblique holes 110 distributed in a circumference are provided on the frustum 109 .

[0042] In this embodiment, after the gas enters the annular plate 111, it will enter the exhaust pipe 101 through the inclined hole 110 on the cone 109. The gas can rotate at high speed through the action of the cone 109 and the inclined hole 110 to achieve a heating effect. It should be noted that the working principle of the vortex tube heater in this application is the same as that in the prior art, so its specific working process will not be described in detail here.

[0043] Embodiment 2:

[0044] Reference Figure 1-Figure 10 An energy-saving double-sided high-efficiency vortex tube heater comprises a metal outer tube 1, and an exhaust pipe 101 and an exhaust pipe 2 102 arranged at both ends of the metal outer tube 1, and further comprises: a sleeve 103 sleeved on the metal outer tube 1, a fixing sleeve 104 is arranged on the sleeve 103, an air inlet pipe 2 is arranged on the metal outer tube 1, and the fixing sleeve 104 is sleeved on the outer wall of the air inlet pipe 2; a fixing ring 3 is also provided, and a connecting pipe 301 is provided between the fixing ring 3 and the inner wall of the metal outer tube 1; a baffle 303 is rotatably provided at the bottom of the fixing ring 3, and four baffles 303 are provided, and rubber pads 304 are respectively provided on the outer walls of the four baffles 303, and the rubber pads 304 on the four baffles 303 are fitted together; an inclined plate 4 is rotatably provided inside the metal outer tube 1.

[0045] In the initial state, the rubber pads 304 on the four baffles 303 fit together, so that the intake pipe 2 is in a closed state, which can avoid unnecessary flow of gas when there is no heating demand, thereby reducing energy waste, achieving efficient use of energy, and achieving energy saving. The four baffles 303 block the intake pipe 2, which can prevent dust, moisture, etc. from entering the vortex tube, thereby causing damage to the vortex tube heater and ensuring its service life. The vortex tube heater uses the high-speed rotation of the compressed gas to generate vortexes, so that heat is generated inside the heated object, and then the heated gas is discharged through the exhaust pipe 1 101, and the cold air can be discharged through the exhaust pipe 2 102. The heating method is highly efficient, reduces energy loss in the heat conduction process, and improves energy saving effects.

[0046] Reference Figure 5 , Figure 8 and Fig.10 A sliding ring 201 is slidably arranged between the air inlet pipe 2 and the fixed tube 104, and a push rod 203 is fixedly connected to the bottom of the sliding ring 201. Slide grooves are arranged on the metal outer tube 1, the sleeve 103, the connecting tube 301 and the fixed ring 3, and the push rod 203 is slidably connected in the slide groove. When the push rod 203 moves downward, it will push the baffle 303 to rotate.

A support plate 302 is provided on the bottom outer wall of the fixed ring 3, and the baffle 303 is rotatably arranged on the support plate 302. A first torsion spring 305 is provided between the outer wall of the baffle 303 and the support plate 302, and the bottom outer wall of the fixed ring 3 is fixedly connected to a limiting plate 306.

[0048] In this embodiment, a pipeline for conveying gas is connected to the air intake pipe 2. Specifically, a threaded groove is provided on the air intake pipe 2, which can enable the air intake pipe 2 to be threadedly connected to the pipeline for conveying gas, so that the connection is tighter. Then the pipeline for conveying gas will push the sliding ring 201 to slide between the air intake pipe 2 and the fixed cylinder 104, thereby driving the push rod 203 fixedly connected to the bottom of the sliding ring 201 to move, so that it pushes the baffle 303, so that the baffle 303 rotates between the two support plates 302. At this time, the four baffles 303 will all rotate synchronously. Therefore, the rubber pads 304 on the four baffles 303 will no longer fit each other. At this time, the gas can enter through the four baffles 303, and because the four baffles 303 are all inclined, they can also guide the gas to a certain extent, thereby ensuring the flow rate of the gas and facilitating the heating operation.

[0049] When the sliding ring 201 moves downward, the elastic member 204 is also compressed. When the gas conveying pipeline is removed, the sliding ring 201 can be automatically reset through the elastic member 204, which is convenient for repeated use. The elastic member 204 can specifically be a spring. The limiting plate 306 is provided to limit the baffle 303 to prevent it from rotating too much.

[0053] Reference Figure 3-Figure 5 and Figure 7 A piston plate 501 is slidably connected in the cylinder 5, a hollow rod 502 is fixedly connected to the piston plate 501, the hollow rod 502 is connected to the cylinder 5, a fine hole 503 is provided on the sliding ring 201, and the two ends of the fine hole 503 are respectively connected to the annular airbag 202 and the hollow rod 502.

[0054] Reference Figure 3-Figure 5 The cylinder 5 is provided with a plurality of cylinders, each of which is connected to two annular airbags 202. When the piston plate 501 in the cylinder 5 moves downward, the annular airbags 202 can be expanded.

[0055] In this embodiment, on the basis of the above-mentioned embodiment 2, after the gas delivery pipe is connected to the intake pipe 2, the sliding ring 201 will be driven to move. At this time, the sliding ring 201 will not only drive the push rod 203 to move, thereby driving the baffle 303 to rotate, so that the gas passes through, but also drive the hollow rod 502 to move, so that the hollow rod 502 drives the piston plate 501 slidably connected in the cylinder 5 to slide, thereby compressing the gas in the cylinder 5, so that the gas between the piston plate 501 and the bottom inner wall of the cylinder 5 enters the hollow rod 502, and then enters the annular airbag 2 through the fine hole 503. 02, thereby expanding the annular airbag 202. It should be noted that when the gas conveying pipeline is connected to the air inlet pipe 2, its bottom will be connected between the two annular airbags 202, and the two annular airbags 202 are connected to the cylinder 5 through the hollow rod 502. Therefore, when the hollow rod 502 drives the piston plate 501 to move, it can inflate the two annular airbags 202 at the same time, so that the two annular airbags 202 are expanded and respectively wrap the bottom sides of the gas conveying pipeline, so that it is sealed with the sliding ring 201 to avoid gas leakage and ensure the use effect.

A blocking rod 108 is fixedly connected to the inner wall of the metal outer cylinder 1, and the blocking rod 108 is arranged on the side of the inclined plate 4 away from the limiting strip 402.

[0057] In the above-mentioned second embodiment, it is mentioned that when the sliding ring 201 moves, the sliding ring 201 will drive the push rod 203 to move, thereby driving the baffle 303 to rotate. In this process, when the baffle 303 rotates, it will also push the inclined plate 4 to rotate, thereby making the inclined plate 4 more inclined. At this time, the gas passing through the four baffles 303 can be more conveniently discharged to the inclined plate 4, and then enter the inclined hole 110 on the cone 109 through the inclined inclined plate 4, thereby realizing high-speed rotation and performing heating operation. Secondly, on the inclined plate 4 A rubber plate 401 is provided to prevent wear of one of the baffles 303 when it contacts the inclined plate 4, making it easier to use. Secondly, when the baffle 303 is working, it will drive the first torsion spring 305 to work, and when the inclined plate 4 rotates, it will drive the second torsion spring 405 to work. When resetting, the first torsion spring 305 and the second torsion spring 405 can reset the baffle 303 and the inclined plate 4, and when the inclined plate 4 is reset, it will also push one of the baffles 303 in reverse, thereby driving the other baffles 303 to move, and assisting multiple baffles 303 to achieve a resetting effect.

[0058] In actual use, the limit strip 402 can further limit the gas so that it can flow better along the inclined plate 4. The blocking rod 108 is provided to prevent the inclined plate 4 from rotating too far and being unable to reset.
