Description

Technical Field:

[0001] The utility model relates to the field of machinery, and particularly relates to an angle adjusting device for a spray pipe of a drum dryer. Background Art:

[0002] Many industrial wastewaters are high-salt wastewaters, and desalination of the high-salt wastewaters is required before discharging. In the wastewater treatment process, a drum scraper dryer can be used. High-temperature steam is introduced into the drum to increase the temperature of the drum surface. Then, wastewater is introduced into a water tank. When the drum rotates, its surface is immersed in the wastewater. While evaporating the wastewater, salt crystals are formed on the drum surface, and finally, the salt crystals are removed by a scraper (knife). Currently, since the method of immersing the drum surface in wastewater has low efficiency and few salt crystals are formed on the drum surface, most of them sink to the bottom, resulting in poor desalination effect. Therefore, a spray pipe is used to directly spray the wastewater on the drum surface. When the wastewater evaporates, more salt crystals will be formed on the drum surface.

[0003] However, since the distance from the spray nozzle of the spray pipe to the drum surface is fixed, when the amount of wastewater decreases, it is difficult to spray the wastewater more effectively on the drum, reducing the desalination amount. Secondly, when the amount of wastewater increases, the wastewater impacts the drum surface, and more wastewater splashes and falls off without adhering to the drum surface, also reducing the desalination amount.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model

[0024] Embodiment 1:

[0025] As Figures 1 - 5 shown, an angle adjustment device for the spray pipe of a drum dryer includes a drum dryer body 1 and a spray pipe 2 rotatably penetrating the drum dryer body 1. It also includes a storage tank 3, a water pump 4, a water inlet pipe 5, a water outlet pipe 6, a rotary joint 7, and a manual rotation device 8. The circulating water outlet of the storage tank 3 is connected to the inlet of the water pump 4, the outlet of the water pump 4 is connected to one end of the water inlet pipe 5, the other end of the water inlet pipe 5 is connected to the water inlet end of the spray pipe 2 through the rotary joint 7, the water outlet end of the spray pipe 2 is connected to one end of the water outlet pipe 6 through the rotary joint 7, and the other end of the water outlet pipe 6 is connected to the circulating water inlet of the storage tank 3

[0026] The water pump 4 pumps out the salt-containing wastewater in the storage tank 3, passes through the water inlet pipe 5 and the rotary joint 7 to the spray pipe 2, and sprays out from the spray nozzle of the spray pipe 2 onto the drum surface. Part of the wastewater that has not been sprayed out returns to the storage tank 3 through the rotary joint 7 and the water outlet pipe 6 on the other side of the spray pipe 2

[0027] A valve 9 is provided on the water outlet pipe 6. By controlling the opening degree of the valve 9, the flow rate of the wastewater in the spray pipe 2 can be adjusted

[0028] The manual rotation device 8 includes a turbine 8.1, a worm 8.2, a crank 8.3, and a U-shaped frame 8.4. The turbine 8.1 is sleeved and fixed on the water inlet end of the spray pipe 2. The U-shaped frame 8.4 is placed outside the turbine 8.1. Both ends of the worm 8.2 rotatably penetrate through the side walls of the U-shaped frame 8.4, and the worm 8.2 meshes with the turbine 8.1. One end of the worm 8.2 is fixed to the crank 8.3, and the U-shaped frame 8.4 is fixed to the bracket of the drum dryer body 1; by rotating the worm 8.2 on the U-shaped frame 8.4 through the crank 8.3, the turbine 8.1 is driven to rotate, further driving the circumferential rotation of the spray pipe 2, so that the nozzle of the spray pipe 2 approaches or moves away from the drum surface, achieving the purpose of adjusting the distance between the nozzle of the spray pipe 2 and the drum surface.

[0029] The storage tank 3 is provided with a water inlet, and the high-salt wastewater input by the external system is replenished into the storage tank 3 from the water inlet.

[0030] It further includes an automatic rotation device 10. The automatic rotation device 10 includes a cylinder 11. The cylinder body of the cylinder 11 is rotatably connected to the bracket of the drum dryer body 1. The telescopic rod of the cylinder 11 is rotatably connected to two side plates 13 through a rotating shaft 12, and the side plates 13 are fixed to the water inlet end of the spray pipe 2. When the telescopic rod of the cylinder 11 extends and retracts, the spray pipe 2 is driven to rotate through the rotating shaft 12 and the two side plates 13, and the distance between the nozzle of the spray pipe 2 and the drum surface can also be adjusted. And by removing the rotating shaft 12, the telescopic rod of the cylinder 11 is separated from the two side plates 13, so that the manual rotation device 8 can be used without interfering with the automatic rotation device 10 for switching use.

[0031] Working principle: When this Embodiment 1 is in use, the cylinder 11 of the automatic rotation device 10 is utilized. Its telescopic rod extends and retracts, driving the spray pipe 2 to rotate through the rotating shaft 12 and the two side plates 13 to adjust the distance between the nozzle of the spray pipe 2 and the drum surface. Or the rotating shaft 12 is removed to separate the telescopic rod of the cylinder 11 from the two side plates 13, and the manual rotation device 8 is switched. The worm 8.2 is rotated through the crank 8.3 to drive the circumferential rotation of the turbine 8.1 and the spray pipe 2, so that the nozzle of the spray pipe 2 approaches or moves away from the drum surface, achieving the purpose of adjusting the distance between the nozzle of the spray pipe 2 and the drum surface.

[0032] When the amount of wastewater increases, the spray pipe 2 is rotated to lift its nozzle, increasing the distance to the drum surface to reduce the splashing amount. The wastewater effectively drips on the drum surface, and the valve 9 cooperates to increase the opening degree to accelerate the flow, avoiding the wastewater being trapped in the spray pipe 2 and the large water spraying pressure at the nozzle; when the amount of wastewater decreases, the spray pipe 2 is rotated to make its nozzle approach the drum surface, shortening the distance to the drum surface, so that the wastewater can still effectively drip on the drum surface. The valve 9 cooperates to reduce the opening degree to reduce the flow, so that the wastewater stays in the spray pipe 2 for a longer time and more goes out from the nozzle.

[0033] Embodiment 2:

[0034] As Figures 6 - 8 shown, an angle adjusting device for a spray pipe 2 of a drum dryer has the same overall structure as that of Embodiment 1. The difference is that it further includes an automatic rotation device 10. The automatic rotation device 10 includes a stepper motor 14 and a sleeve 15. The stepper motor 14 is fixed to the bracket of the drum dryer body 1. The output shaft of the stepper motor 14 is coaxially arranged with the other end of the worm 8.2. A sleeve 15 is movably sleeved between the output shaft of the stepper motor 14 and the end of the worm 8.2. A keyway 16 is provided on the inner wall of the sleeve 15. Key blocks 17 matching the keyway 16 are fixed on both the output shaft of the stepper motor 14 and the end of the worm 8.2. A bolt 18 is screwed on the sleeve 15 and movably penetrates through the keyway 16, the key block 17, and the end of the worm 8.2.

[0035] Working principle: When this Embodiment 2 is in use, by using the stepper motor 14 of the automatic rotation device 10, its output shaft rotates. Through the key block 17 placed in the keyway 16, the sleeve 15 is driven to rotate, and then the worm 8.2 is driven to rotate. The worm 8.2 drives the spray pipe 2 to rotate circumferentially through the turbine 8.1 to adjust the distance between the spray nozzle of the spray pipe 2 and the drum surface. Or remove the bolt 18, and use the keyway 16 to retract the sleeve 15 along the key block 17 to the output shaft of the stepper motor 14, so that the output shaft of the stepper motor 14 is separated from the worm 8.2, and switch to the manual rotation device 8 to make the spray nozzle of the spray pipe 2 close to or away from the drum surface, so as to achieve the purpose of adjusting the distance between the spray nozzle of the spray pipe 2 and the drum surface.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
