Description

Technical Field

[0001] This invention relates to the field of MVR evaporator technology, specifically to a vibrating plate type anti-scaling MVR evaporator. Background Technology

[0002] Currently, MVR evaporators are a new type of high-efficiency and energy-saving evaporation equipment widely used in industries such as chemical, pharmaceutical and food processing. They are mainly used for evaporation, concentration and crystallization in production processes. This equipment uses low temperature and low pressure steam technology and clean energy to generate steam and separate water from the medium. It is an internationally advanced evaporation technology and an upgraded product to replace traditional evaporators. MVR evaporators are generally composed of heat exchangers, circulating pumps, separators, heaters and compressors.

[0003] In existing wastewater treatment processes, evaporators are typically used as the main downstream treatment equipment, responsible for concentrating wastewater and removing dissolved substances. However, many industrial wastewaters contain substances that are prone to scaling, such as salts, minerals, organic matter, and other solid particles. These substances easily deposit on the heat exchange surface during evaporation, forming structures. Scaling significantly reduces heat exchange efficiency. As the scale layer forms, the thermal resistance of the heat exchange surface increases, further reducing heat transfer efficiency. This means that to achieve the same evaporation effect, the equipment needs to consume more energy, leading to increased operating costs and a greater economic burden on enterprises.

[0015] Preferably, a stabilizing slide rod is fixedly installed on the side end face of the circular plate, the end of the stabilizing slide rod away from the circular plate extends into the interior of the cold side inlet pipe and is fixedly installed with an intercepting mesh frame, and a stirring shaft is fixedly installed on the end of the reciprocating screw away from the L-shaped fixed plate, and stirring blades are fixedly installed on the stirring shaft.

[0016] Preferably, the driving sprocket is driven by a chain and the driven sprocket, the stabilizing slide plate is slidably installed with the stabilizing groove, the end of the stirring shaft away from the reciprocating screw extends into the interior of the cold side inlet pipe, and the stirring blade is positioned inside the intercepting mesh frame.

[0017] This invention provides a vibrating plate type anti-fouling MVR evaporator. Compared with the prior art, it has the following advantages:

[0018] 1. This invention uses a drive motor to rotate a drive rod, which in turn drives a main bevel gear. The main bevel gear meshes with a driven bevel gear, and the driven bevel gear, when rotating, drives the mounting ring on the U-shaped fixed plate to rotate via an auxiliary shaft. The elastic plate on the mounting ring intermittently contacts the convex block assembly and the auxiliary ring through the conical head on the striking rod. Through the elasticity of the elastic plate, the circular head on the striking rod reciprocates to strike the vibration transmission plate. The vibration transmission plate then transmits the vibration force to the heat exchange plate in the heat exchanger, effectively knocking off the dirt in the heat exchanger, ensuring the operation of the heat exchanger, and effectively improving the performance of the MVR evaporator.

[0019] 2. In this invention, when the drive rod rotates, it will synchronously drive the main helical gear to rotate. Through the meshing of the main helical gear and the helical gear group on the auxiliary ring, the auxiliary ring will rotate in the annular groove by the limiting ring block and the limiting ring groove. Through the opposite rotation of the auxiliary ring and the mounting ring, the contact effect between the conical rod and the convex block group is better, which improves the striking effect of the conical head on the striking rod on the vibration transmission plate, making the entire evaporator more efficient when working.

[0020] 3. In this invention, when the drive rod rotates, it synchronously drives the active sprocket to rotate. The active sprocket drives the driven sprocket to rotate via a chain. When the driven sprocket rotates, it drives the reciprocating screw to rotate. The reciprocating block on the reciprocating screw is limited by the crescent pin and the stabilizing slide plate and stabilizing groove, thus being in a reciprocating horizontal movement state. The circular plate on the reciprocating block synchronously drives the intercepting mesh frame on the stabilizing slide rod to move synchronously in the cold side inlet pipe. Through the reciprocating movement of the intercepting mesh frame, impurities in the cold liquid are effectively intercepted, while also preventing impurities from clogging the intercepting mesh frame, ensuring that the entire evaporator can operate normally.

[0021] 4. In this invention, when the reciprocating screw rotates, it will synchronously drive the stirring shaft to rotate. The stirring blades on the stirring shaft will rotate inside the interception mesh frame. The rotational force generated by the stirring blades can improve the flowability of impurities inside the interception mesh frame, reduce the clogging of impurities, improve the working efficiency of the interception mesh frame, and enhance the performance of the evaporator.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8This invention relates to a vibrating plate type anti-fouling MVR evaporator, comprising a compressor, a heater, a separator, a circulating pump, and a heat exchanger 1 connected to each other. A cold-side inlet pipe 2 and a hot-side inlet pipe 3 are fixedly connected to the side end face of the heat exchanger 1, with the cold-side inlet pipe 2 positioned to the side of the hot-side inlet pipe 3. The side end face of the heat exchanger 1 has both a cold-side outlet and a hot-side outlet. The cold-side inlet pipe 2 is connected to the outlet of the circulating pump, which draws coolant from a storage tank or other source and delivers it to the heat exchanger 1. The working process is as follows: the coolant is pressurized by the circulating pump and flows into the cold-side inlet pipe 2 of the heat exchanger 1, where it exchanges heat with the steam in the hot-side inlet pipe 3. The hot-side inlet pipe 3 is connected to the steam supply port of the heater, which provides a heat source by introducing steam or other heat medium into the hot side. The working process is as follows: the hot fluid from the heater enters the hot-side inlet pipe 3 of the heat exchanger 1, transferring heat to the coolant through a heat exchange process. The cold-side outlet pipe is connected to the inlet of the separator. The coolant here flows out after heat exchange, and may have already begun to partially evaporate or cool down. The workflow is as follows: the coolant flows out of heat exchanger 1 through the cold side outlet and enters the separator for further processing or separation. The hot side outlet is connected to the compressor inlet. The steam that has undergone heat exchange flows out from the hot side outlet and enters the compressor for compression. The workflow is as follows: after the steam is compressed in the compressor, its temperature and pressure increase, and then it returns to the hot side inlet pipe 3 to continue participating in heat exchange. This principle, as well as the cold side outlet and hot side outlet on heat exchanger 1, are technologies well known to those skilled in the art and will not be described in detail here.

[0033] An L-shaped fixed plate 4 is fixedly installed on the side end face of heat exchanger 1, outside the cold side inlet pipe 2. An interception assembly is provided on the L-shaped fixed plate 4. A mounting plate 5 and a stabilizing horizontal plate 6 are fixedly installed on heat exchanger 1. An auxiliary assembly is provided on the mounting plate 5 and the stabilizing horizontal plate 6. A vibration transmission plate 7 is provided on the auxiliary assembly and is fixedly installed on heat exchanger 1, contacting the heat exchange plates in heat exchanger 1. The auxiliary assembly includes a drive motor 8 fixedly installed on the mounting plate 5. A drive rod 9 is fixedly installed at the output end of the drive motor 8. A main bevel gear 10 is fixedly installed on the drive rod 9. An auxiliary rotating shaft 11 is rotatably installed on the stabilizing horizontal plate 6. A driven bevel gear 12 is fixedly installed at one end of the auxiliary rotating shaft 11, and a U-shaped fixed plate 13 is fixedly installed at the other end of the auxiliary rotating shaft 11. A U-shaped fixed plate 13 is fixedly installed on the U-shaped fixed plate 13. A mounting ring 14 is fixedly installed, and an elastic plate 15 is fixedly installed on the inner side of the mounting ring 14. A striking rod 16 is fixedly installed on the elastic plate 15. A circular head 17 is fixedly installed at one end of the striking rod 16, and a conical head 18 is fixedly installed at the other end of the striking rod 16. An auxiliary ring 19 is provided on the inner side of the U-shaped fixed plate 13. A ring-shaped convex block assembly 20 is fixedly installed on the inner side of the auxiliary ring 19. The main bevel gear 10 meshes with the driven bevel gear 12. The driven bevel gear 12 is located outside the stabilizing horizontal plate 6. The conical head 18 slides in contact with the convex block assembly 20 and the auxiliary ring 19 in sequence. The circular head 17 makes intermittent contact with the vibration transmission plate 7. The connection relationship between the compressor, heater, separator, circulating pump and heat exchanger 1 is a technology well known to those skilled in the art and will not be described in detail here.

[0034] In this embodiment, the drive motor 8 drives the drive rod 9 to rotate, which in turn drives the main bevel gear 10 to rotate. The main bevel gear 10 meshes with the driven bevel gear 12. When the driven bevel gear 12 rotates, it drives the mounting ring 14 on the U-shaped fixed plate 13 to rotate via the auxiliary rotating shaft 11. The elastic plate 15 on the mounting ring 14 intermittently contacts the convex block group 20 and the auxiliary ring 19 through the conical head 18 on the striking rod 16. Through the elastic action of the elastic plate 15, the circular head 17 on the striking rod 16 reciprocates to strike the vibration transmission plate 7. The vibration transmission plate 7 transmits the vibration force to the heat exchange plate in the heat exchanger 1, effectively knocking off the dirt in the heat exchanger 1, ensuring the operation of the heat exchanger 1, and effectively improving the performance of the MVR evaporator.

[0035] A main helical gear 21 is fixedly installed at the end of the drive rod 9 away from the drive motor 8. An annular groove 22 is opened on the inner side of the U-shaped fixed plate 13. A limiting annular groove 23 is opened inside the annular groove 22. A driven helical gear set 24 is fixedly installed on the front surface of the auxiliary ring 19. A limiting annular block 25 is fixedly installed on the outer side of the auxiliary ring 19. A first stabilizing plate 38 and a second stabilizing plate 39 are fixedly installed on the stabilizing plate 6. The drive rod 9 is rotatably installed with the first stabilizing plate 38 and the second stabilizing plate 39. The main helical gear 21 meshes with the driven helical gear set 24. The limiting annular block 25 is slidably installed with the limiting annular groove 23. The auxiliary ring 19 is slidably installed with the annular groove 22. The limiting annular block 25 slides within the limiting annular groove 23 to ensure that the auxiliary ring 19 will not disengage when rotating within the annular groove 22, and to ensure the stability of the auxiliary ring 19 during rotation.

[0036] In this embodiment, when the drive rod 9 rotates, it will synchronously drive the main helical gear 21 to rotate. Through the meshing of the main helical gear 21 with the helical gear group 24 on the auxiliary ring 19, the auxiliary ring 19 will rotate in the annular groove 22 by the limiting ring block 25 and the limiting ring groove 23. Through the opposite rotation of the auxiliary ring 19 and the mounting ring 14, the contact effect between the tapered rod and the convex block group 20 is better, which improves the striking effect of the tapered head 18 on the striking rod 16 on the vibration transmission plate 7, making the entire evaporator more efficient when working.

[0037] The interception assembly includes a reciprocating screw 26 rotatably mounted on an L-shaped fixed plate 4, a driven sprocket 27 fixedly mounted on the reciprocating screw 26, a driving sprocket 28 fixedly mounted on a drive rod 9, a reciprocating block 29 movably mounted on the reciprocating screw 26, a crescent pin 30 movably mounted on the reciprocating block 29, a circular plate 31 fixedly mounted on the side end face of the reciprocating block 29, a stabilizing slide plate 32 fixedly mounted on the circular plate 31, a stabilizing groove 33 formed on the L-shaped fixed plate 4, a stabilizing slide rod 34 fixedly mounted on the side end face of the circular plate 31, and the end of the stabilizing slide rod 34 away from the circular plate 31 extending into the interior of the cold side inlet pipe 2 and fixedly mounted with a barrier. The intercepting frame 35 has a stirring shaft 36 fixedly installed at the end of the reciprocating screw 26 away from the L-shaped fixed plate 4. The stirring shaft 36 is fixedly installed with stirring blades 37. The driving sprocket 28 is driven by the driven sprocket 27 through a chain. The stabilizing slide plate 32 and the stabilizing slide groove 33 are slidably installed. The end of the stirring shaft 36 away from the reciprocating screw 26 extends into the interior of the cold side inlet pipe 2. The stirring blades 37 are located inside the intercepting frame 35. The cold side inlet pipe 2 is equipped with a detachable mounting sleeve. The mounting sleeve and the cold side inlet pipe 2 are detachably installed. The stabilizing slide bar 34 is slidably installed with the mounting sleeve. The reciprocating screw 26 is located on one side of the mounting sleeve.

[0038] In this embodiment, when the drive rod 9 rotates, it synchronously drives the drive sprocket 28 to rotate. The drive sprocket 28 drives the driven sprocket 27 to rotate via a chain. When the driven sprocket 27 rotates, it drives the reciprocating screw 26 to rotate. The reciprocating block 29 on the reciprocating screw 26 is limited by the crescent pin 30, the stabilizing slide plate 32, and the stabilizing groove 33, thus being in a reciprocating horizontal movement state. The circular plate 31 on the reciprocating block 29 synchronously drives the intercepting mesh frame 35 on the stabilizing slide rod 34 to move synchronously in the cold side inlet pipe 2, thereby intercepting... The reciprocating motion of the screen frame 35 effectively intercepts impurities in the coolant, while also preventing impurities from clogging the screen frame 35, ensuring the normal operation of the entire evaporator. When the reciprocating screw 26 rotates, it synchronously drives the stirring shaft 36 to rotate. The stirring blades 37 on the stirring shaft 36 rotate inside the screen frame 35. The rotational force generated by the stirring blades 37 can improve the flowability of impurities inside the screen frame 35, reduce the clogging phenomenon, improve the working efficiency of the screen frame 35, and enhance the performance of the evaporator.

[0039] Working principle: During use, the coolant is pressurized by the circulating pump and flows into the cold side inlet pipe 2 of the heat exchanger 1, where it exchanges heat with the steam in the hot side inlet pipe 3. The hot fluid from the heater enters the hot side inlet pipe 3 of the heat exchanger 1 and transfers heat to the coolant through the heat exchange process. The cold side outlet pipe is connected to the inlet of the separator. The coolant flows out of the heat exchanger 1 through the cold side outlet and enters the separator for further processing or separation. The hot side outlet is connected to the inlet of the compressor. After the steam is compressed in the compressor, its temperature and pressure increase, and then it returns to the hot side inlet pipe 3 to continue to participate in heat exchange.

[0040] When the coolant enters the cooling inlet pipe, the drive motor 8 drives the drive rod 9 to rotate, which in turn drives the main bevel gear 10 to rotate. The main bevel gear 10 meshes with the driven bevel gear 12. When the driven bevel gear 12 rotates, it drives the mounting ring 14 on the U-shaped fixed plate 13 to rotate via the auxiliary rotating shaft 11. The elastic plate 15 on the mounting ring 14 intermittently contacts the convex block group 20 and the auxiliary ring 19 through the conical head 18 on the striking rod 16. Through the elastic action of the elastic plate 15, the circular head 17 on the striking rod 16 reciprocates to strike the vibration transmission plate 7, utilizing the vibration... The moving transmission plate 7 transmits the vibration force to the heat exchange plates in the heat exchanger 1, effectively knocking off the dirt in the heat exchanger 1 and ensuring the operation of the heat exchanger 1. When the drive rod 9 rotates, it synchronously drives the main helical gear 21 to rotate. Through the meshing of the main helical gear 21 with the helical gear group 24 on the auxiliary ring 19, the auxiliary ring 19 will rotate in the annular groove 22 by the limiting ring block 25 and the limiting ring groove 23. Through the opposite rotation of the auxiliary ring 19 and the mounting ring 14, the contact effect between the conical rod and the convex block group 20 is better, improving the contact between the conical head 18 on the striking rod 16 and the convex block group 20. The impact effect of the vibration transmission plate 7 makes the entire evaporator more efficient during operation. When the drive rod 9 rotates, it synchronously drives the drive sprocket 28 to rotate. The drive sprocket 28 drives the driven sprocket 27 to rotate via a chain. When the driven sprocket 27 rotates, it drives the reciprocating screw 26 to rotate. The reciprocating block 29 on the reciprocating screw 26 is limited by the crescent pin 30 and the stabilizing slide plate 32 and stabilizing groove 33, thus being in a reciprocating horizontal movement state. The circular plate 31 on the reciprocating block 29 synchronously drives the intercepting mesh frame 35 on the stabilizing slide rod 34 to enter the cold side pipe. The synchronous motion in step 2, through the reciprocating motion of the intercepting mesh frame 35, effectively intercepts impurities in the coolant, while also preventing impurities from clogging the intercepting mesh frame 35, ensuring the normal operation of the entire evaporator. When the reciprocating screw 26 rotates, it synchronously drives the stirring shaft 36 to rotate. The stirring blades 37 on the stirring shaft 36 rotate within the intercepting mesh frame 35. The rotational force generated by the stirring blades 37 can improve the fluidity of impurities within the intercepting mesh frame 35, reduce the clogging phenomenon, improve the working efficiency of the intercepting mesh frame 35, and enhance the performance of the evaporator.
