[0027] Example 1
[0028] A steam recovery device, such as Figures 1 to 4As shown, the device includes a cooling cylinder 1, a water inlet pipe 3 on one side of the top outer wall of the cooling cylinder 1, a filter cylinder 4 connected to the bottom side wall of the cooling cylinder 1, a steam inlet pipe 2 on the top outer wall of the cooling cylinder 1, a separation box 5 fixedly connected to the bottom outer wall of the cooling cylinder 1, a cooling coil 7 on the inner wall of the cooling cylinder 1, the upper and lower ends of the cooling coil 7 being connected to the steam inlet pipe 2 and the separation box 5 respectively, one end of the filter cylinder 4 being connected to the cooling cylinder 1, a filter plate 14 fixed to the inner wall of the filter cylinder 4, a rotating shaft 8 and a rotating ring 9 rotatably connected to the inner wall of the cooling cylinder 1, the rotating shaft 8 and the rotating ring 9 being located on the inner and outer sides of the cooling coil 7 respectively, and a connecting rod 19 connected to the side of the rotating shaft 8 and the rotating ring 9 near the cooling coil 7, and a cleaning brush 10 fixed to the side wall of the connecting rod 19 by a limiting component, the bristles of the cleaning brush 10 contacting and engaging with the outer wall of the cooling coil 7.
[0029] A gear ring 11 is fixed to the bottom side wall of the rotating ring 9, and a drive gear 12 is fixed to the bottom side wall of the rotating shaft 8. The drive gear 12 and the gear ring 11 are meshed through a transmission gear 13. A motor that drives the rotating shaft 8 to rotate is connected to the bottom end of the rotating shaft 8. Another filter plate 14 is fixed to the inner wall of the separation box 5. An air outlet pipe 6 is connected to one side of the top of the separation box 5. A reflux pump is installed on the side wall of the separation box 5. The output end of the reflux pump is connected to the top of the cooling cylinder 1.
[0030] The limiting component includes a slot 20 and a limiting ball head 21. One end of the connecting rod 19 has a slot 20. The cleaning brush 10 slides in contact with the inner wall of the slot 20. The limiting ball head 21 slides in contact with the side wall of the slot 20. One end of the limiting ball head 21 is limited in contact with the side wall of the cleaning brush 10. The other end of the limiting ball head 21 is connected to the connecting rod 19 by a spring.
[0031] During recovery, steam enters the cooling coil 7 through steam inlet pipe 2, and cooling water enters the cooling cylinder 1 through water inlet pipe 3. As the steam flows along the cooling coil 7, it exchanges heat with the cooling water, recovering the heat from the steam. The cooling water temperature rises and is output through filter cylinder 4. Filter plate 14 filters the cooling water flowing through filter cylinder 4, removing scale and other impurities. Then, the steam enters the separation box 5. The condensate, after being filtered by filter plate 14, gathers in the separation box 5, and the gas flows out through the gas outlet pipe 6. The return pump returns the condensate in the separation box 5 to the cooling cylinder 1. During operation... After a period of time, the motor drives the rotating shaft 8 to rotate, which in turn drives the rotating ring 9 to rotate synchronously through the drive gear 12, transmission gear 13 and gear ring 11. This causes the cleaning brush 10 to clean the outer wall of the cooling coil 7, removing the scale attached to the outside of the cooling coil 7 and preventing the scale from affecting the heat exchange between the steam and the cooling water. When the cleaning brush 10 is worn and needs to be replaced, the cover at the top of the cooling cylinder 1 is opened, and the cleaning brush 10 is pulled upward. The limiting ball head 21 is squeezed and compressed into the connecting rod 19, and the spring is compressed and deformed. Then, the new cleaning brush 10 is inserted into the slot 20, and the limiting ball head 21 limits the cleaning brush 10.
[0032] The filter cylinder 4, rotating shaft 8, rotating ring 9, cleaning brush 10, and filter plate 14 are configured to clean the outer wall of the cooling coil 7, remove the scale attached to the outside of the cooling coil 7, prevent the scale from affecting the heat exchange between steam and cooling water, and filter the cooling water flowing through the filter cylinder 4 to intercept scale and other impurities mixed in the cooling water, preventing scale from entering subsequent equipment.
[0033] By setting a limit component, the cleaning brush 10 can be quickly replaced when it is worn out and needs to be replaced, making the operation convenient.
[0034] Example 2
[0035] A steam recovery device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 2 As shown, a collection chamber 16 is provided at the end of the filter cylinder 4 away from the cooling cylinder 1. A drive shaft 18 is rotatably connected to the inner wall of the collection chamber 16 via a support frame. An impeller 17 is connected to the end of the drive shaft 18 away from the filter plate 14, and a cleaning brush 15 is connected to the other end of the drive shaft 18. The cleaning brush 15 contacts and engages with the side wall of the filter plate 14.
[0036] When cooling water flows out of the filter cartridge 4, the collecting chamber 16 collects the cooling water, speeding up the flow of cooling water. The cooling water impacts the impeller 17, causing the drive shaft 18 to rotate, which drives the cleaning brush 15 to clean the side wall of the filter plate 14, preventing scale from clogging the filter plate 14.
[0037] With a cleaning brush 15, a collecting chamber 16, an impeller 17, and a drive shaft 18, when cooling water flows out of the filter cartridge 4, the collecting chamber 16 collects the cooling water, accelerating the flow of cooling water. The cooling water impacts the impeller 17, causing the drive shaft 18 to rotate, which drives the cleaning brush 15 to clean the side wall of the filter plate 14, preventing scale from clogging the filter plate 14.
[0038] Working principle: During recovery, steam enters the cooling coil 7 through the steam inlet pipe 2, and cooling water enters the cooling cylinder 1 through the water inlet pipe 3. As the steam flows along the cooling coil 7, it exchanges heat with the cooling water, recovering the heat from the steam. The cooling water temperature rises and is output through the filter cylinder 4. The filter plate 14 filters the cooling water flowing through the filter cylinder 4, trapping scale and other impurities. Then, the steam enters the separation box 5. The condensate, after being filtered by the filter plate 14, gathers in the separation box 5, and the gas flows out from the gas outlet pipe 6. The return pump returns the condensate in the separation box 5 to the cooling cylinder 1. After working for a period of time, the motor drives the rotating shaft 8 to rotate, which in turn drives the rotating shaft through the drive gear 12, transmission gear 13, and gear ring 11. The rotating ring 9 rotates synchronously, causing the cleaning brush 10 to clean the outer wall of the cooling coil 7, removing the scale attached to the outside of the cooling coil 7 and preventing the scale from affecting the heat exchange between steam and cooling water. When the cooling water flows out of the filter cylinder 4, the collecting chamber 16 collects the cooling water, accelerating the flow of the cooling water. The cooling water impacts the impeller 17, causing the drive shaft 18 to rotate, which drives the cleaning brush 15 to clean the side wall of the filter plate 14, preventing scale from clogging the filter plate 14. When the cleaning brush 10 is worn and needs to be replaced, open the cover at the top of the cooling cylinder 1, pull the cleaning brush 10 upward, and the limiting ball head 21 is squeezed and compressed into the connecting rod 19. The spring is compressed and deformed. Then, the new cleaning brush 10 is inserted into the slot 20, and the limiting ball head 21 limits the cleaning brush 10.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
