Description

Technical Field

[0001] The invention discloses a full-angle self-regulating cooling device suitable for steam treatment, belonging to the technical field of precise steam utilization. Background Art

[0002] Steam is a clean and safe power source. As an energy source for heating, cooling, extraction, drying, and disinfection equipment, it boasts high efficiency and harmlessness, making it the preferred energy source for applications in the pharmaceutical, food, chemical, and advanced materials industries. Existing heating equipment in these fields typically uses hot water or thermal oil to heat the target. This suffers from low heat exchange efficiency, large inlet and outlet temperature differences, and high heat loss. When saturated steam is used for heat exchange, the steam's latent heat is primarily utilized, which releases more heat in a shorter period of time, achieving high efficiency and precision. Steam releases a very high amount of heat per unit mass (up to 539 kcal / kg or 970 Btu / lb). Currently, the temperature of high-temperature superheated steam cannot be precisely controlled, making accurate heating impossible through steam. This does not meet national energy conservation, emission reduction, and consumption reduction requirements. Summary of the Invention

The bottom of the spring retaining housing 14 is connected to the dispensing barrel 2, and the top is provided with an inwardly facing flange. The lower end of the connecting rod 13 extends into the dispensing barrel 2, and the bottom of the connecting rod 13 is provided with a sealing plate 1301 for sealing the communication port. The upper end of the connecting rod 13 is connected to the cam transmission mechanism via a transmission rod 35. The transmission rod 35 drives the sealing plate 1301 upward or downward to close or open the communication port. The closing spring 16 is sleeved outside the connecting rod 13 and is located within the spring retaining housing 14. The closing spring 16 is in a stretched state. The bottom of the closing spring 16 is connected to the sealing plate 1301, and the top is connected to the inward flange of the spring retaining housing 14, thereby ensuring that the sealing plate 1301 maintains the sealing state of the communication port. The cooling water enters the spring fixing housing 14 through the communication port, and enters the housing through the gap between the upper end of the spring fixing housing 14 and the connecting rod 13 .

[0034] A locating pin 15 is provided at the bottom of the connecting rod 13. The locating pin 15 is arranged along the radial direction of the connecting rod 13. The locating pin 15 is arranged in the spring fixing housing 14. The inner wall of the spring fixing housing 14 is provided with an axial guide groove.

[0035] The housing comprises a lower housing 10 and an upper housing 11. The bottom of the lower housing 10 is sealed with the dispensing barrel 2. The top of the upper housing 11 is sealed and has a water outlet 12. The bottom of the upper housing 11 is detachably connected to the lower housing 10 via bolts, and the lower housing 10 and upper housing 11 are sealed together. A mounting plate 17 is disposed horizontally between the upper and lower housings 11 and 10.

[0036] The transmission rod 35 is mounted on the upper side of the mounting plate 17. The middle portion of the transmission rod 35 is rotatably mounted on the mounting plate 17 via a mounting shaft 18, forming a lever mechanism. Connections 3501 are provided at each end of the transmission rod 35. The mounting plate 17 has openings that face the two connection portions 3501 of the transmission rod 35. The cam transmission mechanism and connecting rod 13 are arranged sequentially from left to right. The top of the cam transmission mechanism passes through the corresponding openings and is hingedly connected to the corresponding connection portion 3501 of the transmission rod 35. The upper end of the connecting rod 13 passes through the corresponding openings and is hingedly connected to the corresponding connection portion 3501 of the transmission rod 35. Cooling water can also flow from the lower housing 10 into the upper housing 11 through the openings.

[0037] The cam transmission mechanism includes a cam 4 and a push rod 5. Cam 4 is coaxially mounted on linkage shaft 3 and rotates synchronously with linkage shaft 3. The upper end of push rod 5 passes through the corresponding opening on the side and is hingedly connected to the corresponding connection portion 3501 of transmission rod 35. The bottom of push rod 5 slidably extends into dispensing barrel 2 and is supported on the corresponding cam 4. Due to the elastic force of closing spring 16, the bottom of push rod 5 always presses against cam 4.

[0038] A push rod sealing ring 8 is provided between the push rod 5 and the distribution barrel 2. The push rod sealing ring 8 is a cone with a diameter gradually increasing in the direction away from the distribution barrel 2. The push rod sealing ring 8 is sleeved on the outside of the push rod 5, and the push rod sealing ring 8 is located on the upper side of the distribution barrel 2. A clamping nut 9 is threadedly connected to the push rod 5, and the clamping nut 9 compresses the push rod sealing ring 8, thereby ensuring a reliable seal between the push rod 5 and the distribution barrel 2.

[0039] like Figure 5 As shown, the input port of the delivery tube is connected to the corresponding water outlet 12, and the output port is equipped with a nozzle 23. The output port of the delivery tube is equipped with a connector 21 and a connecting cover 22. One end of the connecting cover 22 extends into the corresponding nozzle 23 and is threadedly connected to the nozzle 23. The connecting cover 22 and the nozzle 23 are sealed together. The other end of the connecting cover 22 is provided with a spherical connecting cavity 2201. One end of the connector 21 extends into the output port of the delivery tube and is sealed therewith. The other end of the connector 21 is provided with a spherical ball head 2101. The ball head 2101 can be rotatably inserted into the connecting cavity 2201, and an O-ring 24 is provided between the ball head 2101 and the connecting cavity 2201. Both the connector 21 and the connecting cover 22 are provided with channels for cooling water to flow through. The ball head 2101 and the connecting cavity 2201 can rotate relative to each other to adjust the position of the nozzle 23.

[0040] The conveyor drum includes an adjustment motor 20 and a rotating drum 19. The rotating drum 19 is configured into several sections, each with a beveled end. The drums 19 are connected end to end, and adjacent drums 19 are rotatably connected. Each drum 19 is provided with a flow channel 1901 for cooling water. An adjustment motor 20 is installed between each adjacent section of the rotating drum 19. The adjustment motor 20 is mounted on any one of the rotating drums 19. The output shaft of the adjustment motor 20 is connected to the other rotating drum 19, driving the rotating drum 19 to rotate, thereby adjusting the spray angle of the nozzle 23 within a wide adjustment range.

[0041] A gear ring is provided around the end of the rotating cylinder 19 and is provided along the groove on the corresponding side of the rotating cylinder 19. A gear is installed on the output shaft of the adjusting motor 20. The gear is engaged with the gear ring on the corresponding side, thereby causing relative rotation between adjacent rotating cylinders 19.

[0042] like Figures 6-8As shown, each adjacent rotating cylinder 19 is connected by a connecting cylinder 25. The diameter of the end of each rotating cylinder 19 is larger than the diameter of the middle portion. A mounting cavity 1903 is formed at the end of the rotating cylinder 19. A groove 1902 is provided around the inner wall of the mounting cavity 1903, and two grooves 1902 are provided on the inner wall of each mounting cavity 1903 at intervals. A protruding portion 2501 is provided around the outer wall of each connecting cylinder 25, and two protruding portions 2501 are provided at intervals on each end of the connecting cylinder 25. The end of the connecting cylinder 25 extends into the mounting cavity 1903 on the corresponding side, and each protruding portion 2501 can slide into the groove 1903 on the corresponding side, thereby achieving the connection between the two adjacent rotating cylinders 19.

[0043] A seal 26 is provided between each rotating cylinder 19 and the corresponding connecting cylinder 25. The seal 26 is sleeved outside the connecting cylinder 25 and is located between the two grooves 1902 on the corresponding sides, thereby ensuring reliable sealing between the two adjacent rotating cylinders 19 to avoid leakage.

[0044] A dovetail boss 2601 is provided around the inner wall of seal 26, and a dovetail groove is provided around the outer wall of connecting tube 25 to mate with dovetail boss 2601. Dovetail boss 2601 fits into the groove to ensure relative fixation between seal 26 and connecting tube 25, ensuring secure installation of seal 26. Outwardly projecting sealing bosses 2602 are provided at both ends of seal 26. These bosses, along the inner and outer walls of both ends of seal 26, ensure a secure seal between seal 26 and connecting tube 25, as well as between seal 26 and the corresponding rotating tube 19.

[0045] like Figures 9-10 As shown, nozzle 23 includes a nozzle body, a spiral disk 28 disposed within the nozzle body, and a disturbance device. Spiral disk 28 is arranged to rotate relative to the nozzle body and perpendicular to the direction of water flow. The disturbance device is mounted on spiral disk 28 and rotates synchronously with spiral disk 28. Spiral disk 28 rotates under the influence of the water flow, driving the disturbance device to rotate, thereby disturbing the cooling water within the nozzle body, preventing scale from forming within the nozzle body. This fundamentally solves the problem of scale clogging the nozzle body's water outlet and ensures stable operation of the nozzle.

[0046] The nozzle body includes a nozzle cover 27 . The upper portion of the nozzle cover 27 is cylindrical, and the lower portion is conical with a diameter gradually decreasing from top to bottom. A water spray port 2701 is provided at the bottom of the nozzle cover 27 .

[0047] A stirring shaft 31 is coaxially mounted within the nozzle housing 27 and is fixed relative to the nozzle housing 27. The lower end of the stirring shaft 31 extends to the upper side of the water spout 2701. The upper portion of the stirring shaft 31 is mounted within the nozzle housing 27 via a connecting plate (not shown). One end of the connecting plate is connected to the upper portion of the stirring shaft 31, and the other end is connected to the inner wall of the nozzle housing 27. Several connecting plates are spaced around the stirring shaft 31. In this embodiment, three connecting plates are spaced around the stirring shaft 31, which ensures that the stirring shaft 31 is securely mounted while avoiding obstruction to the water flow.

[0048] The spiral disk 28 includes an inner mounting ring 2803, an outer mounting ring 2801 and blades 2802. The outer mounting ring 2801 is coaxially sleeved on the outside of the inner mounting ring 2803, and the outer mounting ring 2801 and the inner mounting ring 2803 are spaced apart. The blades 2802 are arranged between the inner mounting ring 2803 and the outer mounting ring 2801. The inner end of the blade 2802 is connected to the inner mounting ring 2803, and the outer end is connected to the outer mounting ring 2801. Several blades 2802 are spaced apart around the inner mounting ring 2803.

[0049] The inner mounting ring 2803 is coaxially sleeved on the outer side of the middle portion of the stirring shaft 31 . The inner mounting ring 2803 is rotatably mounted on the stirring shaft 31 through a bearing 32 , so that the spiral disk 28 can rotate around the stirring shaft 31 .

[0050] The inner wall of the nozzle outer cover 27 is provided with guide wings. In this embodiment, the guide wings include upper guide wings 29 arranged on the upper side of the spiral disk 28 and lower guide wings 30 arranged on the lower side of the spiral disk 28. The upper guide wings 29 and the lower guide wings 30 are both installed on the inner wall of the nozzle outer cover 27. Several upper guide wings 29 and lower guide wings 30 are arranged around the nozzle outer cover 27, and the upper guide wings 29 and the lower guide wings 30 are both spiral.

[0051] The agitation device includes an agitation sleeve 33 and a cleaning spike 34. The agitation sleeve 33 is coaxially mounted on the agitation shaft 31 and is positioned below the spiral disk 28. The upper end of the agitation sleeve 33 is fixedly connected to the inner mounting ring 2803 and rotates synchronously with the inner mounting ring 2803. The cleaning spike 34 is mounted on the lower end of the agitation sleeve 33 and is located above the water spray port 2701.

[0052] The cooling water enters the nozzle outer cover 27 from the top of the nozzle outer cover 27, and rotates around the nozzle outer cover 27 under the action of the upper guide wing 29 and the lower guide wing 30. The water flow pushes the spiral disk 28 to rotate through the blades 2802, and then drives the stirring sleeve 33 to rotate. The stirring sleeve 33 cleans the water outlet 2701 through the cleaning thorns 34 to prevent the water outlet 2701 from being blocked due to scaling.

[0053] When the full-angle self-adjusting cooling device suitable for steam treatment is working, the distribution motor 6 drives the linkage shaft 3 to rotate, and the cam 4 rotates synchronously with the linkage shaft 3, and then pushes the connecting rod 13 to move through the push rod 5 and the transmission rod 35, so that the sealing plate 1301 opens or closes the connecting port, thereby realizing the on and off of the cooling water.

[0054] The regulating motor 20 drives the two adjacent rotating cylinders 19 to rotate, thereby adjusting the angle of the nozzle 23 to achieve the spraying of cooling water in all directions, making it convenient to control the spraying direction.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
