Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for industrial furnace equipment, and in particular to a multi-level safety protection device for vacuum sintering furnaces. Background Technology

[0002] Industrial furnace equipment safety protection refers to a series of technical and management measures taken during the design, manufacture, and use of industrial furnaces to ensure the safe operation of the equipment, prevent accidents, and protect the safety of operators and the surrounding environment. As a type of industrial furnace, vacuum sintering furnace is a device for sintering materials in a vacuum environment and is widely used in the processing and manufacturing of materials such as metals and ceramics. Its safety protection measures need to be more rigorous and meticulous.

[0003] Regarding existing related technologies, the inventors believe that they often have the following shortcomings: existing vacuum sintering furnaces often lack efficient isolation and cooling, and cannot effectively prevent the harm to personnel and equipment caused by high temperature and gas leakage. At the same time, the treatment methods for harmful gases and dust generated during the sintering process are simple and have limited effects, making it difficult to meet increasingly stringent environmental protection requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing vacuum sintering furnaces often lack efficient isolation and cooling measures, making it difficult to effectively resist the hazards to personnel and equipment caused by high temperature and gas leakage. In addition, the treatment methods for harmful gases and dust generated during sintering are limited and cannot meet environmental protection requirements. Therefore, we propose a multi-level safety protection device for vacuum sintering furnaces.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-stage safety protection device for a vacuum sintering furnace, comprising a protective box: a door is rotatably connected to one side of the protective box via a hinge, the protective box and the door are connected by a snap fastener, a water tank is fixed to the top of the protective box, a water pump is installed on one side of the water tank, a water supply pipe is fixed to one side of the water pump, the other end of the water supply pipe extends into the interior of the protective box, a nozzle is fixed to the other end of the water supply pipe, the sintering furnace body is arranged inside the protective box, a through groove is opened on one side of the protective box, a fan is installed inside the through groove, a fixing frame is fixed to one side of the protective box, a filter screen is slidably connected inside the fixing frame, an upper shell is fixed to one side of the filter screen, a lower shell is fixed inside the fixing frame, a lower protrusion is provided inside the lower shell, a pull rod is fixed to one end of the lower protrusion, an upper protrusion is slidably connected to one side of the lower protrusion, an elastic locking block is fixed to one side of the upper protrusion, and a T-shaped groove for cooperating with the elastic locking block is opened inside the upper shell.

[0006] Preferably, a first slider is fixed to one side of the lower protrusion, and a first groove is provided inside the lower housing to cooperate with the first slider.

[0007] Preferably, a spring is fixed to the other end of the lower protrusion, and the other end of the spring is fixed to the lower housing.

[0008] Preferably, a second slider is fixed at both ends of the upper protrusion, and a second groove is provided inside the lower housing to cooperate with the second slider.

[0009] Preferably, push rods are slidably connected to both ends inside the upper housing, and a push plate is fixed to one end of each push rod.

[0010] Preferably, sealing gaskets are fixed at both ends of the side of the box door that contacts the protective box, and sealing grooves that cooperate with the sealing gaskets are opened at both ends of one side of the protective box.

[0011] Preferably, a drain pipe is fixed to one side of the protective box, and a control valve is provided on the surface of the drain pipe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, pushing the pull rod outward causes the lower protrusion to move, which in turn pushes the upper protrusion to move the elastic block towards the upper housing. The two ends of the elastic block are first squeezed by the inclined surfaces inside the T-slot, allowing it to smoothly enter the interior of the T-slot, thus completing the connection between the fixing frame and the filter screen. Through the above setup, the isolation and water spray cooling functions of the protective box effectively prevent the hazards of high temperature and gas leakage to personnel and equipment. At the same time, the nozzle and fan, in conjunction with the air purification function of the filter screen, not only improve the air quality inside the protective box and reduce the corrosion of the equipment by dust and harmful gases, but also reduce environmental pollution and extend the service life of the equipment.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a multi-level safety protection device for a vacuum sintering furnace, including a protective box 1: a door 2 is rotatably connected to one side of the protective box 1 via a hinge, and the protective box 1 and the door 2 are connected by a snap fastener; a water tank 3 is fixed to the top of the protective box 1; a water pump 4 is installed on one side of the water tank 3; a water supply pipe 5 is fixed to one side of the water pump 4; the other end of the water supply pipe 5 extends into the interior of the protective box 1; a nozzle 6 is fixed to the other end of the water supply pipe 5; a sintering furnace body 7 is installed inside the protective box 1; a through groove 8 is opened on one side of the protective box 1; a fan 9 is installed inside the through groove 8; a fixing frame 10 is fixed to one side of the protective box 1; a filter screen 11 is slidably connected inside the fixing frame 10; an upper shell 12 is fixed to one side of the filter screen 11; a lower shell 13 is fixed inside the fixing frame 10; a lower protrusion 14 is provided inside the lower shell 13; a pull rod 15 is fixed to one end of the lower protrusion 14; the lower protrusion... One side of the upper protrusion 16 is slidably connected to the upper protrusion 16, and one side of the upper protrusion 16 is fixed with an elastic locking block 17. The interior of the upper housing 12 is provided with a T-shaped groove 18 that cooperates with the elastic locking block 17. By pushing the pull rod 15 outward, the lower protrusion 14 is moved, which in turn pushes the upper protrusion 16 to move the elastic locking block 17 towards the upper housing 12. The two ends of the elastic locking block 17 are first squeezed by the inclined surface inside the T-shaped groove 18, and smoothly enter the interior of the T-shaped groove 18, thereby completing the connection between the fixing frame 10 and the filter screen 11. Through the above settings, the isolation and water spray cooling functions of the protective box 1 effectively prevent the hazards of high temperature and gas leakage to personnel and equipment. At the same time, the nozzle 6 and the fan 9, together with the air purification function of the filter screen 11, not only improve the air quality inside the protective box 1 and reduce the corrosion of the equipment by dust and harmful gases, but also reduce environmental pollution and extend the service life of the equipment.

[0023] Reference Figure 4 As shown in this embodiment: a first slider 19 is fixed on one side of the lower protrusion 14, and a first groove 20 that cooperates with the first slider 19 is provided inside the lower housing 13. By setting the structure of the first slider 19 and the first groove 20, the movement path of the lower protrusion 14 is effectively restricted, and shaking is avoided.

[0024] Reference Figure 4As shown in this embodiment: a spring 21 is fixed to the other end of the lower protrusion 14, and the other end of the spring 21 is fixed to the lower housing 13. Push rods 24 are slidably connected to both ends inside the upper housing 12. A push plate 25 is fixed to one end of the push rod 24. By setting the structure of the spring 21, when the filter screen 11 needs to be maintained, the push plate 25 is pushed to drive the push rod 24 to squeeze the elastic block 17. At the same time, the rebound force of the spring 21 is used to push the lower protrusion 14 back to the initial position. The lower protrusion 14 drives the upper protrusion 16 to move, so that it drives the elastic block 17 away from the interior of the T-slot 18, thereby releasing the connection between the fixing frame 10 and the filter screen 11, which facilitates the maintenance and cleaning of the filter screen 11.

[0025] Reference Figure 4 As shown in this embodiment: both ends of the upper protrusion 16 are fixed with second sliders 22, and the interior of the lower housing 13 is provided with a second sliding groove 23 that cooperates with the second sliders 22. By setting the structure of the second sliders 22 and the second sliding groove 23, it is ensured that the upper protrusion 16 moves along a predetermined route to prevent deviation.

[0026] Reference Figure 2 As shown in this embodiment: sealing gaskets 26 are fixed at both ends of the side of the door 2 that contacts the protective box 1, and sealing grooves 27 that cooperate with the sealing gaskets 26 are opened at both ends of one side of the protective box 1. By setting the sealing gaskets 26 and the sealing grooves 27, it is ensured that the sealing gaskets 26 can be tightly embedded in the sealing grooves 27, forming a good sealing effect, enhancing the sealing performance of the protective box 1, preventing gas leakage, dust entry and heat loss, and improving the safety and reliability of the equipment.

[0027] Reference Figure 1 and Figure 5 As shown in this embodiment: a drain pipe 28 is fixed on one side of the protective box 1, and a control valve 29 is provided on the surface of the drain pipe 28. By setting the structure of the drain pipe 28 and the control valve 29, the water accumulated in the protective box 1 can be effectively discharged, preventing damage to the device due to excessive water spraying by the nozzle 6, and extending the service life of the device. The control valve 29 can flexibly control the opening and closing of the drain pipe 28 and drain water as needed.

[0028] Working principle: The user pushes the pull rod 15 outward to move the lower protrusion 14, which in turn pushes the upper protrusion 16 to move the elastic block 17 towards the upper housing 12. The two ends of the elastic block 17 are first squeezed by the inclined surface inside the T-slot 18, and smoothly enter the interior of the T-slot 18, thus completing the connection between the fixing frame 10 and the filter screen 11. Through the above settings, the isolation and water spray cooling functions of the protective box 1 effectively prevent the hazards of high temperature and gas leakage to personnel and equipment. At the same time, the nozzle 6 and the fan 9, together with the air purification function of the filter screen 11, not only improve the air quality inside the protective box 1 and reduce the corrosion of the equipment by dust and harmful gases, but also reduce environmental pollution and extend the service life of the equipment. By setting the structure of the first slider 19 and the first slide groove 20, the movement path of the lower protrusion 14 is effectively restricted to avoid shaking. By setting the structure of the spring 21, when the filter screen 11 needs maintenance, the push plate 25 is pushed to drive the push rod 24 to move the elastic block 17. The compression, combined with the rebound force of spring 21, pushes the lower protrusion 14 back to its initial position. The lower protrusion 14 then moves the upper protrusion 16, causing the elastic locking block 17 to leave the interior of the T-slot 18, thereby releasing the connection between the fixing frame 10 and the filter screen 11. This facilitates the maintenance and cleaning of the filter screen 11. The structure of the second slider 22 and the second sliding groove 23 ensures that the upper protrusion 16 moves along a predetermined path, preventing deviation. The sealing gasket 26 and the sealing groove 27 ensure that the sealing gasket 26 can be tightly embedded in the sealing groove 27, forming a good sealing effect. This enhances the sealing performance of the protective box 1, preventing gas leakage, dust entry, and heat loss, thus improving the safety and reliability of the equipment. The structure of the drain pipe 28 and the control valve 29 effectively drains the water accumulated in the protective box 1, preventing damage to the device due to excessive water spraying from the nozzle 6 and extending the service life of the device. The control valve 29 can flexibly control the opening and closing of the drain pipe 28, draining water as needed.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
