Technical Field
[0001] The utility model relates to the technical field of condensers, in particular to a quick cleaning device for heat exchange tubes of condensers. Background Art
[0002] The heat exchange tube is an important component in the condenser. The circulating water flowing through the heat exchange tube contains impurities such as silt, which will adhere to the heat exchange tube and form scale, thereby affecting the heat exchange efficiency of the heat exchange tube. If the silt on the heat exchange tube in the condenser is not cleaned for a long time, it will become hard scale that cannot be removed. The heat exchange tube cleaning methods in the prior art include the following: the first is to clean by adding chemical cleaning agents. The advantage of this method is that it can reduce labor costs and is easy to clean. The disadvantage is that during the cleaning process, due to the corrosive properties of chemical cleaning agents, it is easy to damage the inner wall of the heat exchange tube, resulting in unnecessary economic losses; the second is to perform physical cleaning. During physical cleaning, the condenser needs to be shut down first and then cleaned. After cleaning is completed, it cannot be guaranteed that the dirt on the inner wall of the heat exchange tube can be completely discharged from the heat exchange tube, which will greatly reduce the cleaning effect and affect production efficiency. Summary of the Invention
[0003] In order to solve the above problems, the utility model provides a quick cleaning device for heat exchange tubes of a condenser, which can reduce labor costs and improve cleaning effects.
[0004] The technical solution of the utility model is: a quick cleaning device for heat exchange tubes of a condenser, comprising an equipment shell, a heat exchange tube connected to the equipment shell, a cleaning component connected to the heat exchange tube, an auxiliary component connected to the equipment shell and a controller, the cleaning component comprising a rotating shaft movably connected to the heat exchange tube, a spiral cleaning element connected to the rotating shaft and a rotating motor for driving the rotating shaft to rotate, the auxiliary component comprising a sliding rod slidably connected to the equipment shell, a connecting base connected to the sliding rod, a contact plate connected to the connecting base, a vibration motor connected to the connecting base and a first hydraulic cylinder for driving the sliding rod to move along the axial direction of the heat exchange tube, the spiral cleaning element maintains contact with the inner wall of the heat exchange tube, the upper surface of the contact plate contacts with the bottom of the heat exchange tube, the heat exchange tube is provided with a drain outlet and an electromagnetic stop valve connected to the drain outlet, and the controller is electrically connected to the electromagnetic stop valve, the first hydraulic cylinder, the rotating motor and the vibration motor respectively.
[0005] By adopting the above technical solution, when the heat exchange tube needs to be cleaned, first, the controller controls the rotating motor to drive the rotating shaft to rotate, so that the spiral cleaning element continuously rubs against the inner wall of the heat exchange tube, thereby scraping off the dirt attached to the inner wall of the heat exchange tube. At the same time, the controller controls the first hydraulic cylinder to drive the sliding rod to move back and forth along the axial direction of the heat exchange tube, and controls the vibration motor to provide vibration force. Since the upper surface of the contact plate contacts the bottom of the heat exchange tube, the vibration force is transmitted to the contact plate through the connecting base and finally to the heat exchange tube, which can further separate the dirt from the inner wall of the heat exchange tube, thereby improving the cleaning efficiency and cleaning effect. In addition, this cleaning method does not require the heat exchanger to be shut down, nor does it require the staff to disassemble the condenser for cleaning, which can greatly reduce labor costs.
[0006] The present invention is further configured as follows: a rubber pad fixedly connected to the contact plate is provided on the upper surface of the contact plate, and the inner wall of the rubber pad is adapted to the shape and size of the outer surface of the heat exchange tube.
[0007] By adopting the above technical solution, since the upper surface of the contact plate is provided with a rubber pad fixedly connected to the contact plate, it can be avoided that when the contact plate transmits vibration force to the heat exchange tube, frequent friction between the contact plate and the heat exchange tube and wear of the heat exchange tube are caused.
[0008] A further configuration of the present invention is that a plurality of reinforcing ribs are provided at the connection between the contact plate and the connection base.
[0009] By adopting the above technical solution, since a plurality of reinforcing ribs are provided at the connection between the contact plate and the connection base, the connection strength between the contact plate and the connection base can be improved, thereby avoiding excessive vibration amplitude of the contact plate causing wear of the heat exchange tube.
[0010] The utility model is further configured as follows: a flushing port is further provided on the heat exchange tube, a reverse flushing solenoid valve is provided on the flushing port, and the reverse flushing solenoid valve is electrically connected to the controller.
[0011] By adopting the above technical solution, the reverse flushing solenoid valve can be controlled by a controller to open, so that water force enters the interior of the heat exchange tube in the opposite direction, further cleaning the dirt attached to the inner wall of the heat exchange tube. Ultimately, the dirt enters the drain port, and the solenoid shut-off valve is opened by the controller to complete the draining work. The utility model further has the following configuration: the number of the auxiliary components is two, and the two auxiliary components are arranged symmetrically about the center point of the heat exchange tube, one contact plate contacts the top of the heat exchange tube, and the other contact plate contacts the bottom of the heat exchange tube. The two auxiliary components move in opposite directions, and the flushing port and the drain port are both located in the middle of the heat exchange tube.
[0012] By adopting the above technical solution, since the two auxiliary components are symmetrically arranged around the center point of the heat exchange tube, and one of the contact plates contacts the top of the heat exchange tube and the other contact plate contacts the bottom of the heat exchange tube, it can further ensure that the heat exchange tube can be subjected to vibration force in all directions, thereby improving the cleaning effect. In addition, the two first hydraulic cylinders of the controller can be controlled at the same time to drive the two sliding rods to move toward each other, which can greatly reduce the movement stroke of a single sliding rod, thereby increasing the reciprocating motion frequency of the auxiliary component and further improving the cleaning effect.

DETAILED DESCRIPTION
[0015] like Figure 1 As shown, a quick cleaning device for heat exchange tubes of a condenser comprises an equipment housing 1, a heat exchange tube 2 connected to the equipment housing 1, a cleaning assembly 3 connected to the heat exchange tube 2, an auxiliary assembly 4 connected to the equipment housing 1, and a controller 5. The cleaning assembly 3 comprises a rotating shaft 6 movably connected to the heat exchange tube 2, a spiral cleaning element 7 connected to the rotating shaft 6, and a rotating motor 8 for driving the rotating shaft 6 to rotate. The auxiliary assembly 4 comprises a sliding rod 9 slidably connected to the equipment housing 1, a connecting base 10 connected to the sliding rod 9, and a connecting base 11 connected to the connecting rod 12. A contact plate 11 connected to the connection base 10, a vibration motor 12 connected to the connection base 10 and a first hydraulic cylinder 13 for driving the sliding rod 9 to move along the axial direction of the heat exchange tube 2, the spiral cleaning element 7 maintains contact with the inner wall of the heat exchange tube 2, the upper surface of the contact plate 11 contacts the bottom of the heat exchange tube 2, the heat exchange tube 2 is provided with a drain port 14 and an electromagnetic stop valve 15 connected to the drain port 14, and the controller 5 is electrically connected to the electromagnetic stop valve 15, the first hydraulic cylinder 13, the rotating motor 8 and the vibration motor 12 respectively.
[0016] When the heat exchange tube 2 needs to be cleaned, first, the controller 5 controls the rotating motor 8 to drive the rotating shaft 6 to rotate, so that the spiral cleaning element 7 continuously rubs against the inner wall of the heat exchange tube 2, thereby scraping off the dirt attached to the inner wall of the heat exchange tube 2. At the same time, the controller 5 controls the first hydraulic cylinder 13 to drive the sliding rod 9 to move back and forth along the axial direction of the heat exchange tube 2, and controls the vibration motor 12 to provide vibration force. Since the upper surface of the contact plate 11 contacts the bottom of the heat exchange tube 2, the vibration force is transmitted to the contact plate 11 through the connecting base 10 and finally to the heat exchange tube 2. This can further separate the dirt from the inner wall of the heat exchange tube 2, thereby improving the cleaning efficiency and cleaning effect. In addition, this cleaning method does not require the heat exchanger to be shut down, nor does it require the staff to disassemble the condenser for cleaning, which can greatly reduce labor costs.
[0017] A rubber pad 16 fixedly connected to the contact plate 11 is provided on the upper surface of the contact plate 11 , and the inner wall of the rubber pad 16 is adapted to the shape and size of the outer surface of the heat exchange tube 2 .
[0018] Since the upper surface of the contact plate 11 is provided with a rubber pad 16 fixedly connected to the contact plate 11, it can prevent the contact plate 11 from transmitting vibration force to the heat exchange tube 2, causing frequent friction between the contact plate 11 and the heat exchange tube 2 and wear of the heat exchange tube 2.
[0019] A plurality of reinforcing ribs 17 are provided at the connection between the contact plate 11 and the connection base 10 .
[0020] Since the connection between the contact plate 11 and the connection base 10 is provided with a plurality of reinforcing ribs 17, the connection strength between the contact plate 11 and the connection base 10 can be improved, thereby preventing the heat exchange tube 2 from being worn due to excessive vibration amplitude of the contact plate 11.
[0021] The heat exchange tube 2 is further provided with a flushing port 18 , and a reverse flushing solenoid valve 19 is provided on the flushing port 18 . The reverse flushing solenoid valve 19 is electrically connected to the controller 5 .
[0022] The controller 5 can be used to control the backwash solenoid valve 19 to open, allowing water to flow in the opposite direction into the heat exchange tube 2, further cleaning the dirt attached to the inner wall of the heat exchange tube 2. Ultimately, the dirt enters the drain port 14, and the controller 5 opens the solenoid shut-off valve 15 to complete the draining process. There are two auxiliary assemblies 4, which are centrally symmetrically arranged about the center of the heat exchange tube 2. One contact plate 11 contacts the top of the heat exchange tube 2, and the other contact plate 11 contacts the bottom of the heat exchange tube 2. The two auxiliary assemblies 4 move in opposite directions. The flush port 18 and the drain port 14 are both located in the middle of the heat exchange tube 2.
[0023] Since the two auxiliary components 4 are symmetrically arranged around the center point of the heat exchange tube 2, and one of the contact plates 11 contacts the top of the heat exchange tube 2, and the other contact plate 11 contacts the bottom of the heat exchange tube 2, it can further ensure that the heat exchange tube 2 can be subjected to vibration force in all directions, thereby improving the cleaning effect. In addition, the two first hydraulic cylinders 13 of the controller 5 can be simultaneously controlled to drive the two sliding rods 9 to move toward each other, which can greatly reduce the movement stroke of a single sliding rod 9, thereby increasing the reciprocating motion frequency of the auxiliary component 4 and further improving the cleaning effect.
