A heating furnace with a tempering control device

Abstract

This utility model discloses a heating furnace with a tempering control device, including a furnace body and an electric push rod. The electric push rod is fixedly installed on the surface of the furnace body, and a base is fixedly connected to one end of the electric push rod relative to the furnace body. A mounting platform is provided on the top surface of the base. In the above solution, when tempering occurs inside the furnace body, a temperature sensor installed on the surface of the mounting platform can detect the temperature abnormality and send a signal to a controller outside the electric push rod, causing it to retract and move the mounting platform as a whole. Simultaneously, a pump extracts the dry powder stored in the dry powder box. A motor drives a transmission roller to rotate, which, under the transmission belt, drives another transmission roller to rotate synchronously. The controller causes the connecting column to reciprocate, and finally, the nozzle evenly sprays the dry powder into the inner cavity of the furnace body. By immediately treating the tempering, high-temperature burns and mechanical damage are avoided, ensuring the safety of personnel and equipment and improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, and more specifically, to a heating furnace with a tempering control device. Background Technology

[0002] Castings usually need to be heat-treated before use. When a heating furnace heats multiple steel castings at once, the overhead crane needs to lift them multiple times to move them into the cooling pool. This takes a lot of time, affects the continuous operation of the heating furnace, and reduces production efficiency.

[0003] To address the aforementioned issues, patent document publication number CN222007907U describes a casting heating furnace, comprising a trolley furnace body. The trolley furnace body consists of a furnace body with a furnace door at the front end and a trolley. A cooling pool is located at the left front of the furnace body, and a pushing mechanism is located at the right front of the furnace body. The pushing mechanism is used to push the castings on the trolley from right to left into the cooling pool. The pushing mechanism includes a transverse moving seat, which is L-shaped. Two longitudinally distributed pushing cylinders are installed on the vertical side of the transverse moving seat. The pushing cylinders are arranged transversely, and the piston rod of each pushing cylinder extends to the left and is fixed with a pushing plate at its end.

[0004] However, it still has some drawbacks in actual use. For example, the heating furnace directly pushes the castings on the trolley into the cooling pool for cooling through the pushing mechanism, without the need for manual hoisting by the crane. This helps the trolley furnace to quickly carry out the next heat treatment. However, the heating furnace may experience tempering during use, and the furnace body itself does not have a corresponding control device, so it cannot deal with the tempering in time, which reduces the practicality of the device to a certain extent.

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heating furnace with a tempering control device to solve the problem that tempering in the prior art heating furnace cannot be dealt with in a timely manner.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heating furnace with a tempering control device, comprising a furnace body, and the heating furnace with the tempering control device further comprising...

[0007] An electric push rod is fixedly installed on the surface of the furnace body. A base is fixedly connected to one end of the electric push rod relative to the furnace body, and a mounting platform is provided on the top surface of the base.

[0008] A fixing frame is fixedly connected to one side of the mounting platform in the width direction;

[0009] Motor 1 is fixedly installed on the surface of the mounting platform near the fixed frame. The drive shaft of Motor 1 is fixedly connected to a transmission roller 1. A transmission belt is provided on the outside of the transmission roller 1. The transmission roller 1 is connected to a transmission roller 2 via the transmission belt. One side of the transmission roller 2 is rotatably connected to the surface of the fixed frame.

[0010] A connecting column, the side end of which is fixedly connected to one side of the transmission roller relative to the fixed frame, and a nozzle is provided on the surface of the connecting column;

[0011] The pump is fixedly installed on the surface of the mounting platform on the side opposite to the motor. The two ports of the pump are respectively fixedly connected to the connecting pipe one and the connecting pipe two. One end of the connecting pipe one is fixedly connected to the dry powder box, which is set on the surface of the mounting platform. One end of the connecting pipe two is fixedly connected to the end of the connecting column opposite to the transmission roller two.

[0012] It also includes a stabilizing frame, which is fixedly installed on the surface of the furnace body, and the top of the stabilizing frame is sleeved with the surface of the extension end of the electric push rod.

[0013] It also includes a sealing assembly, which is disposed at the top of the furnace body.

[0014] The sealing assembly includes a mounting frame, a connecting plate, a rack, a sealing plate, a mounting plate, a second motor, and a gear. The mounting frame is fixedly installed on the top surface of the furnace body. The connecting plate is movably installed on the inner wall of the mounting frame. The rack is disposed on the surface of the connecting plate. The sealing plate is fixedly installed on the bottom of the connecting plate, and the surface of the sealing plate is in contact with the inner wall of the furnace body. The mounting plate is disposed on the surface of the sealing plate. The second motor is fixedly installed on the surface of the mounting frame. One side of the gear is fixedly connected to the drive shaft of the second motor, and the outer edge of the gear meshes with the outer edge of the rack.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, when backfire occurs inside the furnace, the temperature sensor on the surface of the mounting plate can detect the abnormal temperature and send a signal to the controller outside the electric push rod, causing it to retract and move the entire mounting platform. The extraction pump extracts the dry powder stored in the dry powder box and transmits it to the connecting column through the second connecting pipe. As the mounting platform moves gradually and the connecting column enters the furnace through the side opening of the furnace, the first motor drives the first transmission roller to rotate, and under the transmission belt, it drives the second transmission roller to rotate synchronously. The controller causes the connecting column to reciprocate and rotate. Finally, the nozzle evenly sprays the dry powder into the inner cavity of the furnace to treat the backfire in time. By treating the backfire in time, high temperature burns and mechanical damage are avoided, ensuring the safety of personnel and equipment and improving the practicality of the device.

[0017] The set motor drives the gear to rotate. When the rack is engaged with the gear, the sealing plate can move down and abut against the inner wall of the furnace to seal the opening used for immediate tempering treatment, ensuring the negative pressure balance in the furnace cavity and further improving the practicality of the device.

[0029] The pump 12 is fixedly installed on the surface of the mounting platform 4 on the side opposite to the motor 6. The two ports of the pump 12 are respectively fixedly connected to the connecting pipe 14 and the connecting pipe 15.

One end of the connecting pipe 15 is fixedly connected to the end of the connecting column 10 opposite to the transmission roller 9.

[0030] It also includes a stabilizing frame 16, which is fixedly installed on the surface of the furnace body 1. The top of the stabilizing frame 16 is sleeved with the extended end surface of the electric push rod 2. The stabilizing frame 16 can stabilize the electric push rod 2 when it extends and retracts, so as to avoid excessive pressure from the mounting platform 4 and corresponding components, which would affect the normal extension and retraction of the electric push rod 2.

[0031] It also includes a sealing assembly 17, which is disposed on the top of the furnace body 1.

[0032] The sealing assembly 17 includes a mounting frame 171, a connecting plate 172, a rack 173, a sealing plate 174, a mounting plate 175, a second motor 176, and a gear 177. The mounting frame 171 is fixedly installed on the top surface of the furnace body 1. The connecting plate 172 is movably installed on the inner wall of the mounting frame 171. The rack 173 is disposed on the surface of the connecting plate 172.

[0033] The electric push rod 2, motor 6, extraction pump 12, and motor 176 are all equipped with external control terminals, namely PLC controllers, which can receive signals from the temperature sensor located on the side of the mounting plate 175 near the inner cavity of the furnace body 1, so as to control the corresponding components connected to them and achieve the effect of automatic tempering.

[0034] The working process of this utility model is as follows: When backfire occurs inside the furnace body 1, the temperature sensor set on the surface of the mounting plate 175 can sense the abnormal temperature and send a signal to the controller outside the electric push rod 2, causing it to retract and drive the mounting platform 4 to move as a whole. The extraction pump 12 extracts the dry powder stored in the dry powder box 13 and transmits it to the connecting column 10 through the connecting pipe 15. When the mounting platform 4 moves gradually and the connecting column 10 enters the furnace body 1 through the side opening of the furnace body 1, the motor 6 drives the transmission roller 7 to rotate, and under the transmission of the transmission belt 8, it drives the transmission roller 9 to rotate synchronously. The controller causes the connecting column 10 to reciprocate and flip. Finally, the nozzle 11 sprays the dry powder evenly into the inner cavity of the furnace body 1 to treat the backfire in time.
