Description

A heat recovery and utilization device for quenching support rollers Technical Field

[0001] This utility model relates to the field of support roller quenching technology, and in particular to a heat recovery and utilization device for support roller quenching. Background Technology

[0002] Chinese patent document CN217479509U discloses a heat recovery device for a quenching furnace, including a heat recovery unit body and a water tank. An air inlet pipe is fixedly connected to one side of the heat recovery unit body. A filter mechanism is provided on the outer wall of the air inlet pipe. The filter mechanism includes a filter box and a movable plate. A dustproof component is provided on the front of the movable plate. The dustproof component includes two filter plates and two fixing slots. The two filter plates are respectively set in the inner cavity of the two fixing slots through two snap-fit ​​mechanisms. By using the arrangement of the filter box, the movable plate, the two filter plates, and the two fixing slots, when the filter plates in the filter box need to be cleaned, only the movable plate needs to be pulled. The movable plate moves the upper filter plate and simultaneously moves the filter plate that was originally in the lower position into the filter box for timely replacement. This allows the filter plates to be cleaned without affecting heat recovery, avoiding clogging and thus improving the efficiency of heat recovery.

[0003] However, the above-mentioned device does not have a heat diversion operation, and the heat is difficult to enter the device actively and at a constant speed. This results in slow and unstable heat exchange between the heat source and the heating tube, which easily leads to more heat loss after the water source absorbs heat, resulting in low heat recovery efficiency. Therefore, we propose a heat recovery and utilization device for quenching support rollers. Summary of the Invention

[0004] The purpose of this invention is to provide a heat recovery and utilization device for quenching support rollers, which can solve the problem of unstable heat recovery in some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat recovery and utilization device for quenching support rollers, comprising:

[0006] A heat exchange box, on which heat exchange tubes are fixedly installed;

[0007] The filtration mechanism, which is installed on the heat exchange tube, is used to filter the heat coming out of the quenching furnace.

[0008] The heat exchange tube has a flow-guiding mechanism located at one end. The flow-guiding mechanism includes an installation cylinder, a fixing plate, a servo motor, and a fan. The fixing plate is fixedly installed on the inner wall of the installation cylinder. The servo motor is fixedly installed at the bottom of the fixing plate. The fan is rotatably installed on the top of the fixing plate. The shaft of the servo motor is connected to the fan drive.

[0009] Preferably, the diversion mechanism further includes a protective railing. One end of the heat exchange tube communicates with the interior of the mounting cylinder. At least two sets of protective railings are fixedly installed on the inner wall of the mounting cylinder. With the cooperation of the heat exchange tube and the diversion mechanism, a negative pressure can be generated in the heat exchange tube, allowing heat to flow uniformly within the heat exchange tube. Efficient and stable heat exchange is achieved through the heat exchange tube, which is in direct contact with the water source. This solves the problem that some existing devices do not have a heat diversion operation, making it difficult for heat to actively and uniformly enter the device, resulting in slow and unstable heat exchange between the heat source and the heating tube. This can easily cause more heat loss after the water source absorbs heat, resulting in low heat recovery efficiency. This improves the practicality of the device.

[0010] Preferably, the filtration mechanism includes a filter box, a mesh frame, and a filter screen. The filter box is fixedly installed on the top of the heat exchange box and is also fixedly mounted on the heat exchange tube. The heat exchange tube is disconnected from the inside of the filter box. A slot is provided through the front side of the filter box, and a mesh frame is inserted into the slot. A filter screen is fixedly installed on the inner wall of the mesh frame. Under the action of the filtration mechanism, impurities contained in the heat from the quenching furnace can be filtered to avoid direct discharge to the outside environment and pollution, thus ensuring the effectiveness of the device and facilitating its promotion and use.

[0011] Preferably, a water inlet pipe communicating with the interior of the heat exchange box is fixedly installed on the top of the heat exchange box.

[0012] Preferably, a water outlet pipe communicating with the interior is fixedly installed on one side of the outer surface of the heat exchange box, and a solenoid valve is fixedly installed on the water outlet pipe.

[0013] Preferably, a flange is fixedly installed at the other end of the heat exchange tube, and a sealing gasket is fixedly installed on one side of the outer surface of the flange.

[0014] Preferably, a temperature sensor is fixedly installed on one inner wall of the heat exchange box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The heat recovery and utilization device for quenching support rollers can generate negative pressure in the heat exchange tube through the cooperation of heat exchange tube and flow diversion mechanism, so that heat flows uniformly in the heat exchange tube. The heat exchange tube that is in direct contact with the water source can carry out efficient and stable heat exchange. This solves the problem that some existing devices do not have heat diversion operation, and heat is difficult to enter the device actively and uniformly, resulting in slow and unstable heat exchange between heat and heating tube, which easily causes more heat loss after the water source absorbs heat, resulting in low heat recovery efficiency. This improves the practicality of the device.

[0017] (2) The heat recovery and utilization device for quenching of support rollers can filter the impurities contained in the heat coming out of the quenching furnace through the filtration mechanism, so as to avoid direct discharge to the outside world and cause pollution, thus ensuring the effectiveness of the device and facilitating its promotion and use.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please refer to Figures 1-4. This utility model provides a technical solution: a heat recovery and utilization device for quenching support rollers, including a heat exchange box 1, a filter mechanism 4 and a diversion mechanism 3. A heat exchange tube 2 is fixedly installed on the heat exchange box 1. The filter mechanism 4 is installed on the heat exchange tube 2 and is used to filter the heat from the quenching furnace. A water inlet pipe 5 communicating with the interior is fixedly installed on the top of the heat exchange box 1. A water outlet pipe 6 communicating with the interior is fixedly installed on the outer surface of one side of the heat exchange box 1. A solenoid valve 7 is fixedly installed on the water outlet pipe 6. A flange 8 is fixedly installed at the other end of the heat exchange tube 2. A sealing gasket 9 is fixedly installed on the outer surface of one side of the flange 8. A temperature sensor 10 is fixedly installed on the inner wall of one side of the heat exchange box 1.

[0026] The flow guiding mechanism 3 is located at one end of the heat exchange tube 2. The flow guiding mechanism 3 includes an installation cylinder 31, a fixing plate 32, a servo motor 33 and a fan 34. The fixing plate 32 is fixedly installed on the inner wall of the installation cylinder 31. The servo motor 33 is fixedly installed at the bottom of the fixing plate 32. The fan 34 is rotatably installed on the top of the fixing plate 32. The rotating shaft of the servo motor 33 is connected to the fan 34 for transmission.

[0027] The diversion mechanism 3 also includes a protective railing 35. One end of the heat exchange tube 2 is connected to the interior of the mounting cylinder 31. At least two sets of protective railings 35 are fixedly installed on the inner wall of the mounting cylinder 31. Through the cooperation of the heat exchange tube 2 and the diversion mechanism 3, a negative pressure can be generated in the heat exchange tube 2, so that the heat flows uniformly in the heat exchange tube 2. The heat exchange tube 2, which is in direct contact with the water source, can carry out efficient and stable heat exchange. This solves the problem that some existing devices do not have a heat diversion operation, and the heat is difficult to enter the device actively and uniformly, resulting in slow and unstable heat exchange between the heat and the heating tube. This can easily cause more heat loss after the water source absorbs heat, resulting in low heat recovery efficiency. This improves the practicality of the device.

[0028] The filtration mechanism 4 includes a filter box 41, a mesh frame 42, and a filter screen 43. The filter box 41 is fixedly installed on the top of the heat exchange box 1. The filter box 41 is also fixedly installed on the heat exchange tube 2. The heat exchange tube 2 is disconnected from the inside of the filter box 41. A slot is provided through the front side of the filter box 41. The mesh frame 42 is inserted into the slot. The filter screen 43 is fixedly installed on the inner wall of the mesh frame 42. Through the filtration mechanism 4, impurities contained in the heat from the quenching furnace can be filtered to avoid direct discharge to the outside environment and pollution. This ensures the effectiveness of the device and is conducive to its promotion and use.

[0029] Working principle: Water is quantitatively injected into the heat exchange box 1 through the inlet pipe 5. The heat exchange tube 2 is connected to the quenching furnace through the flange 8, so that the heat exchange tube 2 is connected to the inside of the quenching furnace. The servo motor 33 is started and drives the fan 34 to rotate, introducing the heat of the quenching furnace into the heat exchange tube 2. It first passes through the filter screen 43 and then enters the heat exchange tube 2 inside the water source in the heat exchange box 1. After exchanging heat with the water source, it is finally discharged through the installation cylinder 31. When the temperature sensor 10 detects that the water source has reached the required temperature, the solenoid valve 7 opens and the water source is discharged through the outlet pipe 6 for storage or use. The screen frame 42 is replaced and the filter screen 43 is cleaned regularly.
