Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a heat exchanger of a waste heat dryer. Background Art

[0002] Compressed air refers to a gas that meets the pressure and temperature required for production after air is compressed and cooled in multiple stages by air compressors, waste heat dryers and other equipment. It has a wide range of uses and is an indispensable power source in industrial production. The compressed air generated is stored in compressed air tanks and used for air flow transportation and as a power source for pneumatic devices and pneumatic instruments to supply other downstream work sections.

[0003] The existing waste heat dryer heat exchanger is not convenient for real-time monitoring of the sealing of the gas pipeline during heat exchange during actual use, which will result in the staff being unable to know in time when a leak occurs accidentally, thereby causing heat energy loss.

[0004] For this reason, we propose a waste heat dryer heat exchanger to solve the above technical problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a heat exchanger for a waste heat dryer, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat exchange row of a waste heat dryer comprises a base plate, a dryer body is fixedly installed on the top of the base plate, one end of a connecting pipe is fixedly connected to the inner wall of the dryer body, the other end of the connecting pipe is fixedly connected to the heat exchange row body, one end of a connecting pipe is fixedly connected to the side of the heat exchange row body away from the connecting pipe, the other end of the connecting pipe is fixedly connected to a heat exchange tank, a detection tube is fixedly connected to the outer edge of the connecting tube, a voice announcer is fixedly installed on the top of the detection tube, a support rod is fixedly connected to the inner top of the detection tube, a tympanic membrane 1 is fixedly connected to the bottom of the support rod, an electrode sheet 1 is fixedly installed on the bottom of the tympanic membrane 1, a tympanic membrane 2 is fixedly installed on the inner wall of the detection tube, an electrode sheet 2 is fixedly installed on the top of the tympanic membrane 2, and a fixing frame is fixedly installed on the bottom of the base plate.

[0007] As a preferred technical solution of the utility model, a motor is fixedly installed at the bottom of the base plate, a screw is fixedly installed on the power output shaft of the motor, a lifting plate is threadedly connected to the outer edge of the screw, and four rollers are symmetrically fixedly installed at the bottom of the lifting plate.

[0008] By adopting the above technical solution, the driving motor drives the screw rod to rotate, which can drive the lifting plate and the roller to move up and down, and then store the roller to ensure that the roller will not contact the ground, thereby ensuring that the roller will not contact the ground when it does not need to move, thereby reducing the pressure of the device itself on the roller.

[0009] As a preferred technical solution of the utility model, the eardrum 2 and the eardrum pair are arranged opposite to each other, the middle position of the eardrum 2 is elastic, and the positions of the electrode sheet 1 and the electrode sheet 2 correspond to each other.

[0010] By adopting the above technical solution, when the gas is discharged into the inner cavity of the detection tube without leakage, the eardrum 2 can be used to push the electrode piece 2 to move to contact the electrode piece 1, so as to detect the sealing of the inner cavity of the connecting tube in real time. When leakage occurs, the air pressure is insufficient to push the electrode piece 2 to contact the electrode piece 1.

[0011] As a preferred technical solution of the utility model, a fixing plate is fixedly assembled on the inner bottom of the fixing frame, a bearing is fixedly assembled on the top of the fixing plate, and the bottom end of the screw rod is fixedly connected to the inner wall position of the bearing.

[0012] By adopting the above technical solution, it is possible to limit the screw rod during rotation, thereby ensuring that the screw rod can rotate in a vertical state for a long time, thereby ensuring the stability of the screw rod during rotation.

[0013] As a preferred technical solution of the utility model, a controller is fixedly mounted on the outer edge of the dryer body, and the electrode sheet 1, the electrode sheet 2, the voice announcer and the controller are all electrically connected.

[0014] By adopting the above technical solution, when the gas in the inner cavity of the connecting pipe flows normally and the electrode sheet 2 is not in contact with the electrode sheet 1, a signal will be transmitted to the controller, and then the controller will control the voice announcer to broadcast a warning sound, thereby alerting the staff to the need to inspect and maintain the connecting pipe in time.

[0015] As a preferred technical solution of the utility model, a threaded hole is opened in the middle of the lifting plate, the screw rod is threadedly connected to the inner wall of the threaded hole, the lifting plate is arranged on the inner wall of the fixed frame, and the size of the lifting plate is matched with the inner wall size of the fixed frame.

[0016] By adopting the above technical solution, the rotation of the screw rod can drive the lifting plate and the roller to move up and down through the threaded hole, thereby adjusting the position of the roller.

[0017] Beneficial effects of the utility model:

[0018] 1. By discharging the gas in the inner cavity of the connecting tube to the inner cavity of the detection tube, the eardrum 2 can be used to push the electrode piece 2 to move to the contact with the electrode piece 1, so as to detect the sealing of the inner cavity of the connecting tube in real time. When a leak occurs, the air pressure is insufficient to push the electrode piece 2 to contact the electrode piece 1. At this time, the electrode piece 2 and the electrode piece 1 will transmit the signal to the controller, and then the controller will control the voice announcer to broadcast a warning sound, thereby alerting the staff to promptly inspect and maintain the connecting tube.

[0019] 2. The driving motor drives the screw rod to rotate, which can drive the lifting plate and the roller to move up and down, and then store the roller, thereby ensuring that the roller does not contact the ground when it does not need to move, reducing the pressure of the device itself on the roller and increasing the service life of the roller.

The outer edge of the screw 17 is threadedly connected to a lifting plate 18, and four rollers 19 are symmetrically fixedly installed at the bottom of the lifting plate 18, so that the driving motor 16 drives the screw 17 to rotate, which can drive the lifting plate 18 and the rollers 19 to move up and down, and then the rollers 19 are stored to ensure that the rollers 19 will not contact the ground, and then ensure that the rollers 19 will not contact the ground when they do not need to move, thereby reducing the pressure of the device itself on the rollers 19.

[0028] See also Figure 3 The eardrum 2 13 and the eardrum 1 11 are arranged opposite to each other, the middle position of the eardrum 2 13 is elastic, and the positions of the electrode piece 12 and the electrode piece 14 correspond to each other, so that when the gas is discharged into the inner cavity of the detection tube 8 without leakage in the inner cavity of the connecting tube 6, the eardrum 2 13 can be used to push the electrode piece 2 14 to move to contact the electrode piece 1 12, thereby detecting the sealing of the inner cavity of the connecting tube 6 in real time. When leakage occurs, the air pressure is insufficient to push the electrode piece 2 14 to contact the electrode piece 1 12.
