Description

Technical Field

[0001] This application relates to the field of metal surface treatment equipment technology, and in particular to an integrated temperature control device inside a pressure blackening treatment autoclave. Background Technology

[0002] Metal surface blackening is a process that generates a dense oxide film on the metal surface through a chemical reaction. It is mainly used to improve rust resistance, wear resistance, and appearance. During the pressure blackening process of metal workpieces, temperature is one of the key factors affecting the blackening effect. A suitable and stable temperature can promote a full chemical reaction between the blackening solution and the workpiece, forming a uniform and dense blackening film layer, thereby effectively improving the corrosion resistance and aesthetics of the workpiece.

[0003] The existing temperature control devices for pressurized blackening treatment kettles have many shortcomings. Traditional temperature control devices mostly use external heating and temperature measurement methods. The heat transfer efficiency between the heating element and the inside of the treatment kettle is low, and the heat loss during the transfer process is large, resulting in slow heating speed and high energy consumption. In addition, the existing temperature control devices are relatively decentralized in structure, with heating, temperature measurement and temperature control modules being independent of each other, resulting in poor coordination between the modules.

[0004] Therefore, this application proposes an integrated temperature control device inside a pressurized blackening treatment autoclave. Utility Model Content

[0005] This application proposes an integrated temperature control device for a pressurized blackening treatment autoclave to solve the problems mentioned in the background art. This integrated temperature control device, by incorporating a heating control component, a control center, adjustment buttons, a display screen, conduit, fixing pipe, electric heating wire, and temperature sensor, enables rapid and easily controlled internal temperature rise during operation. The mechanism, by installing the electric heating wire inside the device, reduces heat loss during heat transfer. Furthermore, the intelligent control of the control center integrates various modules, improving collaborative efficiency and allowing for timely temperature adjustment within the device, significantly enhancing its practicality.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An integrated temperature control device for a pressurized blackening treatment vessel includes a reaction cylinder. The reaction cylinder has an external support structure and a feeding structure at its top. A stirring mechanism is located at the top and inside the reaction cylinder. A heating control assembly is located at the top and inside the reaction cylinder, including a control center mounted on the top of the reaction cylinder. An adjustment button and a display screen are mounted on the top surface of the control center. A conduit is fixedly connected to one side of the control center, and a fixed pipe is fixedly connected to the bottom of the conduit, communicating with it. The fixed pipe extends into the interior of the reaction cylinder, and its bottom is fixedly connected to the bottom surface of the interior of the reaction cylinder. An electric heating wire is installed inside the fixed pipe and is electrically connected to the control center via an electric wire passing through the conduit. A temperature sensor is installed externally on the stirring mechanism and electrically connected to the control center. A cooling structure is located externally on the reaction cylinder. An exhaust mechanism is located on one side of the reaction cylinder, and a discharge structure is located at the bottom of the reaction cylinder.

[0008] In a preferred embodiment, the support structure includes a support rod, which is fixedly connected to the outside of the reaction cylinder, and a contact block is fixedly connected to the bottom of the support rod;

[0009] The device can be supported by support rods, and contact blocks can be used to increase the contact area between the support rods and the ground, thereby improving the stability of the device and enhancing its practicality.

[0010] In a preferred embodiment, the feeding structure includes a feeding pipe, which is fixedly connected to the top of the reaction cylinder. The feeding pipe communicates with the interior of the reaction cylinder, and a sealing cap is threaded onto the top of the feeding pipe.

[0011] After opening the sealing cap, the blackening treatment liquid and workpiece can be added into the reaction cylinder through the feeding pipe. After adding, tighten the sealing cap to keep the device airtight, thereby improving the practicality of the device.

[0012] In a preferred embodiment, the stirring mechanism includes a motor, which is fixedly connected to the top of the reaction cylinder. A drive rod is fixedly connected to the output end of the motor, and a drive gear is fixedly connected to the outside of the drive rod. A driven rod is rotatably connected to the bottom of the inside of the reaction cylinder, and the driven rod extends to the top of the reaction cylinder. A driven gear is fixedly connected to the outside of the driven rod, and the driven gear meshes with the drive gear. Multiple stirring rods are fixedly connected to the outside of the driven rod located in the inner region of the reaction cylinder.

[0013] The motor drives the drive rod and drive gear to rotate, and the drive gear then drives the driven rod and driven gear to rotate. As the driven gear rotates, the stirring rod also rotates along with the driven gear, thereby stirring the inside of the device, improving working efficiency, and thus enhancing the practicality of the device.

[0014] In a preferred embodiment, the cooling structure includes a water tank, which is fixedly connected to the outside of the reaction cylinder. An inlet plug is slidably connected to the top of the water tank, and an outlet plug is slidably connected to the bottom of the water tank.

[0015] By opening the inlet plug, cooling water can be added to the water tank, which can cool the inside of the reaction cylinder. After cooling is complete, the outlet plug can be opened to discharge the cooling water. This structure can assist the heating control components in controlling the internal temperature of the device, thereby improving the practicality of the device.

[0016] In a preferred embodiment, the exhaust mechanism includes an exhaust pipe, which is fixedly connected to one side of the reaction cylinder. The exhaust pipe communicates with the reaction cylinder. An installation plate is fixedly connected inside the exhaust pipe. A spring is fixedly connected to the outside of the installation plate. A top plate is fixedly connected to the outside of the spring. The top plate contacts the outlet end of the exhaust pipe. An L-shaped rod is fixedly connected to the inside of the top plate. An annular groove is formed on the outer surface of the exhaust pipe, and the L-shaped rod is slidably connected to the annular groove.

[0017] During operation, the reaction chamber generates heat and gas. When the internal pressure is too high, the gas pushes up the top plate, causing the L-shaped rod to slide inside the annular groove and the spring to stretch. After the gas is discharged, the internal pressure decreases, and the spring's restoring force pulls the top plate back to the position where it contacts the exhaust pipe opening. This mechanism can automatically discharge the gas generated inside the device, ensuring stable internal pressure and thus improving the device's practicality.

[0018] In a preferred embodiment, the discharge structure includes a discharge pipe, which is fixedly connected to the bottom of the reaction cylinder. The discharge pipe communicates with the reaction cylinder, and a screw cap is externally threaded to the bottom end of the discharge pipe.

[0019] After the work is completed, the blackening treatment liquid and the workpiece can be taken out together through the discharge pipe by unscrewing the cap, and then the two can be separated, thus improving the practicality of the device.

[0020] In one preferred embodiment, multiple fixing tubes are installed, and each fixing tube is equipped with an electric heating wire inside;

[0021] By installing multiple fixed tubes, the number of electric heating wires can be increased, allowing the internal temperature to rise rapidly during operation, thus improving the device's efficiency and practicality.

[0022] The beneficial effects of this application are:

[0023] 1. This integrated temperature control device for a pressurized blackening treatment vessel, by setting up heating control components, a control center, adjustment buttons, a display screen, conduits, fixing pipes, electric heating wires, and temperature sensors, enables the internal temperature of the device to rise rapidly and be easily controlled during operation. Installing the electric heating wire inside the reaction vessel reduces heat loss during transfer. The temperature sensor monitors the internal temperature in real time; when the temperature deviates from the set value, the sensor transmits a signal to the control center, which then controls the electric heating wire to adjust its intensity. The adjustment buttons allow for parameter adjustment before operation, and the display screen shows the device's operating time. This mechanism, by installing the electric heating wire inside the device, reduces heat loss during transfer. Furthermore, the intelligent control of the control center integrates various modules, improving efficiency and enabling timely temperature adjustment, significantly enhancing the device's practicality.

[0024] 2. This integrated temperature control device inside a pressurized blackening treatment vessel, by setting up an exhaust mechanism, exhaust pipe, mounting plate, spring, top plate, L-shaped rod, and annular groove, can automatically discharge the gas generated inside the device. During operation, heat and gas are generated inside the reaction vessel. When the internal pressure is too high, the gas pushes up the top plate, causing the L-shaped rod to slide inside the annular groove and the spring to stretch. After the gas is discharged, the internal pressure decreases, and under the restoring force of the spring, the top plate is pulled back to the position contacting the opening end of the exhaust pipe. This mechanism can automatically discharge the gas generated inside the device, ensuring stable internal pressure and greatly improving the practicality of the device. Attached Figure Description

The exhaust mechanism 7 includes an exhaust pipe 71, which is fixedly connected to one side of the reaction cylinder 1 and communicates with the reaction cylinder 1.

The L-shaped groove 76 is slidably connected. When the device is working, heat and gas are generated inside the reaction cylinder 1. When the internal pressure of the device is too high, the gas will push up the top plate 74, causing the L-shaped rod 75 to slide inside the annular groove 76 and causing the spring 73 to stretch. After the gas is discharged, the internal pressure of the device decreases. Under the action of the spring 73's own restoring force, the top plate 74 will be pulled back to the position in contact with the opening end of the exhaust pipe 71. This mechanism can automatically discharge the gas generated inside the device, ensuring the stability of the internal pressure of the device, thereby improving the practicality of the device.

[0040] Working Principle: When the device is in operation, the sealing cover 32 is opened, and the blackening treatment liquid and workpiece are added into the reaction cylinder 1 through the feeding pipe 31. After adding, the sealing cover 32 is tightened to keep the device airtight. The motor 41 drives the drive rod 42 and drive gear 43 to rotate, and the drive gear 43 drives the driven rod 44 and driven gear 45 to rotate. At the same time as the driven gear 45 rotates, the stirring rod 46 also rotates with the driven gear 45, thereby stirring the inside of the device. The electric heating wire 56 is installed inside the reaction cylinder 1 to reduce heat loss during the transfer process. The temperature sensor 57 monitors the temperature inside the device in real time. When the temperature deviates from the set value, the temperature sensor 57 will transmit the signal to the control center 51, which will then control the electric heating wire 56 to adjust the intensity of the heating wire 56 in a timely manner. The adjustment button 52 can adjust the parameters as needed before the device starts working. The display screen 53 can display the working status of the device. By installing multiple fixed pipes 55, the number of electric heating wires 56 can be increased, allowing the internal temperature to rise rapidly during operation and improving the efficiency of the device. Opening the inlet plug 62 allows cooling water to be added to the water tank 61, which can cool the inside of the reaction cylinder 1. After cooling, opening the outlet plug 63 allows the cooling water to be discharged. This structure can assist the heating control component 5 in controlling the internal temperature of the device. During operation, heat and gas are generated inside the reaction cylinder 1. When the internal pressure of the device is too high, the gas will push up the top plate 74, causing the L-shaped rod 75 to slide inside the annular groove 76 and causing the spring 73 to stretch. After the gas is discharged, the internal pressure of the device decreases. Under the action of the spring 73's own restoring force, the top plate 74 will be pulled back to the position in contact with the opening end of the exhaust pipe 71. After the work is completed, by unscrewing the cap 82, the blackening treatment liquid and the workpiece can be taken out together through the discharge pipe 81 and then separated.
