This type of heat exchanger is usually used in industries such as power station boilers, iron and steel metallurgy, especially in occasions that require continuous operation and have high requirements for temperature control.

[0003] The rotary heat exchanger includes a rotary air preheater and a rotary flue gas heater. Its working principle is that after high-temperature flue gas enters the rotary heat exchanger, it heats the heat storage elements inside the rotor. As the rotor rotates, the heat carried is transferred to the air or flue gas that needs to be heated on the opposite side. The rotary heat exchanger can be divided into two compartments, three compartments, four compartments, etc. according to the bin form, and can be divided into vertical and horizontal forms according to the layout form.

[0004] Although there are many types of existing rotary heat exchangers, since they are all driven by a power device to drive the transmission component, and then drive the rotor to rotate. Although this method has a relatively simple structure, due to the relatively fixed internal structure of the transmission component, there are problems of difficult installation and maintenance during use.

[0026] Please refer to Figures 1 to 6 , in this embodiment, a transmission device that is convenient for installation includes a fixed chassis 1, a transmission assembly 2 arranged on the top of the fixed chassis 1, and a fixing component 3 arranged on the top of the fixed chassis 1.

[0027] A fixed component 3 is provided to limit the transmission component 2, and the transmission component 2 transmits power to the outside to achieve the purpose of power transmission.

[0028] In this embodiment, the transmission component 2 includes a transmission disc 21 movably connected to the top of the fixed chassis 1, a plurality of fixed frames 22 fixedly installed on the side of the fixed chassis 1, a fixed seat 23 movably connected inside the fixed frame 22, a driven disc 24 rotatably connected to the outside of the fixed seat 23, a bearing seat 25 fixedly installed on the top of the fixed chassis 1, a drive shaft 26 movably connected to the top of the bearing seat 25, and a fixed hole 27 opened on the top of the fixed chassis 1.

[0029] The transmission disc 21 is arranged on the top of the fixed chassis 1 to cooperate with the drive shaft 26 to transmit the power of the motor to the transmission disc 21, and the transmission disc 21 then transmits the power to the driven disc 24 on the outside, thereby realizing the transmission of power.

[0030] In this embodiment, a limit bearing 28 is fixedly installed on the top of the fixed chassis 1. A through groove 211 is opened in the middle of the transmission disc 21. The top of the limit bearing 28 is embedded inside the through groove 211 and is rotatably connected to the inner side wall of the through groove 211. The transmission disc 21 and the driven disc 24 are in meshing transmission connection through the external tooth patterns.

[0031] The limit bearing 28 is arranged on the top of the fixed chassis 1 to limit the transmission disc 21, so that the transmission disc 21 can rotate on the outside of the fixed chassis 1. The transmission connection between the transmission disc 21 and the driven disc 24 enables the power to be smoothly transmitted.

[0032] In this embodiment, a through hole is opened at the top of one end of the fixed frame 22 away from the fixed chassis 1. The top of the fixed seat 23 passes through the through hole and is rotatably connected to the fixed frame 22.

[0033] A through hole is arranged at one end of the fixed frame 22 to cooperate with the fixed seat 23 to limit the driven disc 24, so that the driven disc 24 can rotate stably.

[0034] In this embodiment, the bottom of the drive shaft 26 is embedded in the top of the bearing seat 25 and is rotatably connected to the bearing seat 25. A drive gear 29 is fixedly installed on the outside of the drive shaft 26. Tooth patterns are arranged on the inner wall top of the through groove 211 and are in meshing transmission connection with the drive gear 29.

[0035] The drive shaft 26 is embedded in the bearing seat 25 to limit the bottom of the drive shaft 26. At the same time, the drive gear 29 is arranged on the outside of the drive shaft 26 and is in meshing with the tooth patterns on the inner side wall of the through groove 211, so that the rotation of the drive shaft 26 can smoothly drive the transmission disc 21 to rotate.

[0036] In this embodiment, the fixing component 3 includes a connecting seat 31 movably connected to the top of the fixed chassis 1, a locking disc 32 movably connected to the outside of the connecting seat 31, a plurality of limiting frames 33 fixedly installed on the side of the locking disc 32, and a fixing rod 34 movably connected to the top of the connecting seat 31.

[0037] The connecting seat 31 is arranged on the top of the fixed chassis 1 to limit the locking disc 32, so that the limiting frame 33 and the fixing frame 22 can cooperate to fix the driven disc 24 by the fixing seat 23.

[0038] In this embodiment, the connecting seat 31 has an upper, middle and lower three-layer structure with gradually decreasing sizes. The lowermost layer of the connecting seat 31 is embedded inside the limiting bearing 28 and has a groove 311 on the side. A transmission slot hole 312 penetrating through the middle and upper layers is opened at the top of the groove 311. The driving shaft 26 vertically penetrates through the transmission slot hole 312 and is rotatably connected to the connecting seat 31.

[0039] The three-layer structure of the connecting seat 31 is embedded inside the limiting bearing 28, so that the middle layer of the connecting seat 31 can cooperate with the top layer to fix the locking disc 32 on the top of the transmission disc 21, thus forming a stable structure.

[0040] It should be noted that the bottom of the locking disc 32 is slidably connected to the top of the transmission disc 21, and the top of the driven disc 24 is slidably connected to the bottom of the limiting frame 33.

[0041] In this embodiment, the middle layer of the connecting seat 31 is embedded inside the locking disc 32 and is slidably connected to the inner side wall of the locking disc 32. A positioning through hole 313 is opened at the bottom of the connecting seat 31 above the fixing hole 27. The fixing rod 34 vertically penetrates through the positioning through hole 313 into the fixing hole 27 and is fixedly installed with the fixing hole 27 by threads.

[0042] The middle layer of the connecting seat 31 is embedded inside the locking disc 32, so that the upper layer of the connecting seat 31 can limit the top of the locking disc 32 to prevent the locking disc 32 from rising and falling.

[0043] In this embodiment, a through hole for cooperating with the fixing seat 23 is opened at one end of the limiting frame 33 away from the locking disc 32. A locking nut 35 for fixing the limiting frame 33 is arranged on the top of the fixing seat 23.

[0044] The fixing seat 23 passes through the limiting frame 33 and the fixing frame 22 respectively, so that the limiting frame 33 and the fixing frame 22 can limit the driven disc 24 outside the fixing seat 23 to prevent the driven disc 24 from moving up and down.

[0045] It should be noted that the bottom size of the fixing seat 23 is larger than the middle size, and the size of the locking nut 35 is larger than the size of the through hole.

[0046] The working principle of the above embodiments is as follows:

[0047] By embedding the fixed seat 23 into the perforation of the fixed frame 22, then fixedly installing the fixed chassis 1 on the inner bottom wall of the heat exchanger device, and then nesting the driving disc 21 outside the limiting bearing 28. Since the inner side wall of the through groove 211 of the limiting bearing 28 is provided with tooth threads, the driving disc 21 can be stably placed on the outer side of the top of the limiting bearing 28. While meshing the tooth threads of the driving gear 29 with the tooth threads on the inner wall of the through groove 211, insert the driving shaft 26 into the top of the bearing seat 25, and then mesh the driven disc 24 with the driving disc 21 and nest them on the outside of the fixed seat 23 in sequence, thus completing the meshing of the tooth threads between the driving disc 21, the driven disc 24 and the driving gear 29.

[0048] In addition, by placing the limiting frame 33 and the locking disc 32 on the top of the driven disc 24 and the driving disc 21, then sleeving the connecting seat 31 on the outside of the driving shaft 26 along the driving groove hole 312, passing the fixing rod 34 through the positioning perforation 313 and the fixing hole 27 for threaded fixation, and screwing the locking nut 35 onto the top of the fixed seat 23, the fixing of the connecting seat 31 to the driving shaft 26 and the fixing of the locking disc 32 to the driving disc 21 are realized. At the same time, the limiting frame 33, the fixed frame 22 and the fixed seat 23 cooperate with each other to limit the driven disc 24, thus solving the problem that the installation, disassembly and maintenance of the internal transmission device of the transmission rotary heat exchanger are very inconvenient.

[0049] All the electrical components mentioned in the text are electrically connected to the main controller and the power supply.
