Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an ultrasonic scale prevention type plate heat exchanger. Background Technique

[0002] A plate heat exchanger is a device used to achieve heat transfer between two materials in industrial production or civil use. During the production operation process, the circulating water is prone to scale formation on the heat exchange plates when heated. Since the thermal conductivity of the scale is much lower than that of the heat exchange plates, the attachment of the scale greatly reduces the heat exchange efficiency of the heat exchanger. At the same time, it increases the water flow resistance of the cooling circulating water system and increases the energy consumption of the circulating water pump; the scale is prone to cause under-scale corrosion on the heat exchange plates and even perforate or rupture the heat exchange plates, seriously affecting the operation of the equipment.

[0003] In the prior art, in order to prevent scale from adhering to the surface of the internal structure of the heat exchanger, an ultrasonic structure is installed in the heat exchanger to detach the scale on the surface of the internal structure of the heat exchanger. However, the detached scale will flow out together with the water flow and is likely to block the subsequent structure. For this reason, an ultrasonic scale prevention type plate heat exchanger is proposed. Summary of the Utility Model

[0013] 1.

[0024] A drain cylinder 8 is in contact with the lower side of the filter ring 7. The drain cylinder 8 is coaxially arranged with the water outlet cylinder 5. The drain cylinder 8 and the bottom surface of the heat exchange box 1 are fixed by a bent rod 9. An air cylinder 10 is arranged below the filter ring 7. A jet pump 12 is fixedly communicated with the lower end of the air cylinder 10. A scale removal pipe 11 is arranged above the air cylinder 10. The bottom surface of the scale removal pipe 11 is in sliding contact with the upper surface of the rotating ring 6. The ends of the water outlet cylinder 5 and the drain cylinder 8 close to each other and the ends of the air cylinder 10 and the scale removal pipe 11 close to each other are both arc-shaped. The arc-shaped structures of the water outlet cylinder 5, the drain cylinder 8, the air cylinder 10 and the scale removal pipe 11 are all coaxially arranged with the rotating ring 6.

[0025] The upper surface of the swivel ring 6 is provided with a plurality of scale storage holes 13 that penetrate up and down. The axis of the scale storage hole 13 is arranged parallel to the axis of the swivel ring 6. The plurality of scale storage holes 13 are circumferentially and arrayed around the axis of the swivel ring 6. The scale storage holes 13 store the scale blocked by the filter ring 7.

[0026] The drainage cylinder 8 and the air cylinder 10 are fixed by a flat plate 14. A vertical shaft 18 is coaxially arranged on the inner ring side of the swivel ring 6. The inner ring surface of the swivel ring 6 and the circumferential side surface of the vertical shaft 18 are fixed by a plurality of flat plates 16.

[0029] Working principle: Under the drive of water flow, the scale removed by ultrasonic waves passes through the scale storage holes 13 communicated with the water outlet cylinder 5 and the drainage cylinder 8. The filter ring 7 below the scale storage holes 13 blocks the scale in the scale storage holes 13. The motor 17 intermittently drives the swivel ring 6 to rotate through the vertical shaft 18. Then, during the rotation of the swivel ring 6, the scale storage hole 13 containing scale rotates to communicate with the air cylinder 10. The air jet pump 12 blows air into the communicated scale storage hole 13 through the air cylinder 10, and the air flow drives the scale in the scale storage hole 13 to be discharged through the scale discharge pipe 11. The air flow drives the scale to be ejected from one end located in the storage cylinder 19, so that the storage cylinder 19 stores the scale.
