Description

Technical Field

[0001] This utility model relates to the field of cast iron enamel processing technology, and in particular to an early warning device for abnormal temperature in a cast iron enamel processing furnace. Background Technology

[0002] In the production process of cast iron enamel, firing is a crucial step. It involves melting the enamel powder sprayed onto the surface of the cast iron blank at high temperatures to form a smooth, dense, and robust enamel layer. The temperature profile of this process (including heating rate, peak temperature, holding time, and cooling rate) directly determines the quality of the final product.

[0003] In the existing technology, the shape of the furnace wall varies, mainly divided into flat and curved surfaces. However, when inspecting the furnace wall, the inspection equipment is usually a fixed assembly, which cannot be adapted to the shape of the wall, thus limiting its use.

[0004] Therefore, we propose an early warning device for abnormal temperature in cast iron enamel processing furnaces. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an early warning device for abnormal temperature in cast iron enamel processing furnaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A temperature anomaly early warning device for a cast iron enamel processing furnace, comprising:

[0008] A base plate, on the surface of which are fixedly mounted an audible and visual alarm, a battery compartment, and a handrail frame, with a control panel fixedly mounted at the top of the handrail frame;

[0009] Two guide rods are fixed to the surface of the base plate, and a lifting frame is slidably sleeved between the two guide rods. Multiple adjustable temperature detection mechanisms are fixed on one side of the lifting frame.

[0011] The lifting mechanism, located at the bottom of the lifting frame, is used to adjust the height of the lifting frame.

[0012] In one possible design, the temperature detection mechanism further includes a fixed cylinder, which is fixed to one side of the lifting frame. A slide rod is slidably connected inside the fixed cylinder, and a second screw is rotatably passed through one side of the fixed cylinder. The second screw and the slide rod are threadedly connected.

[0013] In one possible design, the lifting mechanism includes an adjusting sleeve and a first screw. The adjusting sleeve is rotatably connected to the bottom of the lifting frame, and the first screw is fixed to the surface of the base plate. The adjusting sleeve and the first screw are threadedly connected.

[0014] In one possible design, a handwheel is fixed to the outer wall of the adjusting sleeve, and a rocker arm is fixed to one end of the second screw.

[0015] In one possible design, the bottom of the base plate is fixed with brakeable casters.

[0016] In one possible design, the outer wall of the handrail is fitted with a rubber sleeve.

[0017] Beneficial effects: In this utility model, the abnormal temperature early warning device for cast iron enamel processing furnace, through the setting of structures such as slide rod, second screw and fixing sleeve, can adjust the position of multiple temperature sensors according to the shape of the outer wall of the furnace, so that multiple temperature sensors can be attached to the wall at the same time for temperature detection, which improves the flexibility of use.

[0018] In this utility model, the temperature abnormality early warning device for a cast iron enamel processing furnace, through the setting of temperature sensors, lifting frames and first screws, can simultaneously detect the temperature at multiple points on the wall, ensuring the accuracy of the detection;

[0019] In this utility model, the abnormal temperature early warning device for cast iron enamel processing furnace, through the setting of a fixed sleeve, temperature sensor and other structures, facilitates the disassembly and assembly of the temperature sensor by the staff, and provides convenience for later maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In one embodiment: Refer to Figures 1-3 An early warning device includes: a base plate 1, which serves as the basic load-bearing component of the device and is made of metal to ensure the stability of the overall structure.

[0026] The bottom of the base plate 1 is fixedly equipped with four brakeable casters 7, which are distributed at the four corners of the bottom of the base plate 1. The equipment can be easily moved to any testing position near the furnace by using the casters 7. After moving into position, the equipment can be fixed by operating the braking device on the casters 7 to prevent slippage during the testing process.

[0027] A sound and light alarm 2, a battery compartment 3, and a handrail 4 are fixedly mounted on the upper surface of the base plate 1. The battery compartment 3 houses a battery to power the various electrical components of the equipment. A door on the outside of the battery compartment 3 facilitates battery replacement. The handrail 4 is made of stainless steel and is bent into shape, vertically fixed to one edge of the base plate 1. A rubber sleeve 6 is fitted over the outer wall of the handrail 4. The surface of the rubber sleeve 6 has anti-slip textures, increasing friction and improving grip comfort when the operator pushes the equipment, while also preventing hand slippage. A control panel 5 is horizontally fixed at the top of the handrail 4. The control panel 5 integrates a control module and has a display screen and operation buttons. The operation buttons can be used to set temperature warning thresholds, and the display screen shows the detected temperature data in real time.

[0028] Two guide rods 8 are fixedly installed on the upper surface of the base plate 1. The two guide rods 8 are parallel to each other, perpendicular to the base plate 1, and located on the side of the upper surface of the base plate 1 away from the handrail frame 4. A lifting frame 9 is slidably sleeved between the two guide rods 8. The lifting frame 9 has a frame structure, and sliding holes adapted to the guide rods 8 are opened on both sides. The guide rods 8 pass through the sliding holes, so that the lifting frame 9 can slide up and down along the length of the guide rods 8.

[0029] The bottom of the lifting frame 9 is equipped with a lifting mechanism for adjusting its height. The lifting mechanism includes an adjusting sleeve 10 and a first screw 11. The first screw 11 is vertically fixed to the upper surface of the base plate 1 and located in the middle between the two guide rods 8. The adjusting sleeve 10 is a cylindrical structure with internal threads. Its top end is rotatably connected to the center of the bottom of the lifting frame 9 via a bearing. The inner wall of the adjusting sleeve 10 is threadedly connected to the outer wall of the first screw 11. A handwheel is fixed to the outer wall of the adjusting sleeve 10 for easy gripping by the operator. When the handwheel is turned, the adjusting sleeve 10 rotates along with it. Since the first screw 11 remains stationary, the adjusting sleeve 10, under the action of the threads, drives the lifting frame 9 to move up and down along the guide rods 8, thereby adjusting the height of the lifting frame 9 to accommodate furnace inspection points at different heights.

[0030] This application can be used in the field of cast iron enamel processing, as well as in other fields applicable to this application.

[0031] In another embodiment: a temperature abnormality early warning device for a cast iron enamel processing furnace, which is applied to the field of cast iron enamel processing.

[0032] In another aspect of this embodiment, a plurality of adjustable temperature detection mechanisms are fixedly provided on one side of the lifting frame 9. The number of temperature detection mechanisms can be set according to actual detection needs and are evenly distributed along the side of the lifting frame 9. Each temperature detection mechanism includes a fixed cylinder 15, a slide rod 12, a fixed sleeve 13, a temperature sensor 14, and a second screw 16. The fixed cylinder 15 is a hollow cylindrical structure with open ends, horizontally fixed to one side wall of the lifting frame 9. The slide rod 12 is slidably connected inside the fixed cylinder 15 and can slide horizontally along the length of the fixed cylinder 15. The second screw 16 is rotatably inserted through the side wall of the fixed cylinder 15 away from the lifting frame 9. One end of the second screw 16 extends into the interior of the fixed cylinder 15 and is threadedly connected to the end of the slide rod 12 away from the fixed sleeve 13. The other end of the second screw 16 is located outside the fixed cylinder 15 and is fixedly provided with a rocker arm 17. The rocker arm 17 is perpendicular to the second screw 16 for easy rotation by the operator. One end of the slide rod 12 away from the second screw 16 extends out of the fixed cylinder 15 and is fixedly fitted with a fixed sleeve 13. The fixed sleeve 13 is a sleeve with internal threads. The tail of the temperature sensor 14 has external threads. The temperature sensor 14 is threaded through the fixed sleeve 13. By rotating the temperature sensor 14, its length extending out of the fixed sleeve 13 can be adjusted. The temperature sensor 14 is electrically connected to the control module inside the control panel 5 and is used to transmit the detected temperature signal to the control module.

[0033] In use, the operator holds the rubber sleeve 6 on the handrail frame 4 and pushes the equipment to the detection position next to the furnace via the casters 7. The operator then activates the brake on the casters 7 to secure the equipment. Depending on the height of the furnace wall, the operator rotates the handwheel on the adjusting sleeve 10 to raise or lower the lifting frame 9 along the guide rod 8, adjusting the temperature detection mechanism to approximately the height corresponding to the detection position. Depending on the shape of the furnace wall (flat or curved), for each temperature detection mechanism, the operator rotates the rocker arm 17 to drive the second screw 16 to rotate. Under the action of the screw, the slide rod 12 slides along the fixed cylinder 15, adjusting the horizontal distance between the temperature sensor 14 and the furnace wall. This ensures that multiple temperature sensors 14 are aligned with different detection points on the wall, guaranteeing that each sensor can accurately detect the temperature at its corresponding location.

[0034] Temperature warning thresholds are set via the operation buttons on control panel 5. Temperature sensor 14 transmits real-time detected temperature data to the control module on control panel 5. After processing the data, the control module displays the real-time temperature on the screen. When the detected temperature exceeds the preset threshold, the control module triggers audible and visual alarm 2, which emits an audible alarm and flashes a light to promptly alert the operator that the furnace temperature is abnormal, allowing for quick adjustment measures to prevent the firing quality of cast iron enamel from being affected by temperature anomalies.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of the audible and visual alarm 2, battery compartment 3, control panel 5 and temperature sensor 14 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
