Description

Technical Field

[0001] This utility model relates to the field of metallurgical auxiliary equipment technology, and more specifically, to a pre-exposed explosion-proof device for a vacuum melting furnace dust collector. Background Technology

[0002] Currently, before each batch of smelting furnaces is produced, the furnace interior needs to be cleaned. The dust inside the furnace contains powder of alloy products (mainly rare earth metal alloys). When industrial vacuum cleaners are used for collection, they are dry dust collectors. In some cases, the alloy powder spontaneously combusts inside the dust collector due to friction and other reasons, leading to an explosion.

[0003] Furthermore, due to the limitations of the smelting furnace's own structure, the dust collection head of the vacuum cleaner needs to be inserted deep into the furnace cavity, and it is not convenient to directly use a wet dust collector for dust collection. This means that the potential explosion hazard when cleaning the dust inside the smelting furnace has not been effectively eliminated. Utility Model Content

[0004] The main purpose of this utility model is to provide a pre-installed explosion-proof device for a vacuum melting furnace dust collector, which adds humidification to the air inlet of the existing industrial dust collector before it enters the dust collector, thereby preventing alloy powder from spontaneously combusting inside the dust collector.

[0005] To achieve the above objectives, this utility model provides a pre-installed explosion-proof device for a vacuum melting furnace dust collector, installed in the inlet pipe of an industrial dust collector, comprising:

[0006] A ventilation chamber, which is connected to an air inlet pipe and an air outlet pipe;

[0007] The water distribution and humidification section is connected to the air inlet pipe. A water storage container is installed above the air ventilation cavity to supply water to the water distribution and humidification section, or to connect a water supply pipeline to supply water to the water distribution and humidification section.

[0008] In a further improvement, the air inlet pipe is connected to the water inlet pipe, the water inlet pipe is connected to the water storage container, and at the connection between the air inlet pipe and the water inlet pipe, a water inlet is opened on the pipe wall of the air inlet pipe, with the lower part of the water inlet facing the water distribution and humidification part.

[0009] Under the suction of the industrial vacuum cleaner, the air quickly enters the ventilation chamber through the air inlet pipe, blowing away and atomizing the water distributed on the surface of the water distribution and humidification section. The water then enters the ventilation chamber along with the dust, mixing with it and humidifying the dust.

[0010] In a further improvement, the water inlet can be circular, square, or other shapes.

[0011] In a further improvement, the main body of the water distribution and humidification part is shaped like a blade, with one side surface gradually convex from all sides toward the central axis, and the top of this gradually convex side faces the water inlet.

[0012] In a further improvement, the water distribution and humidification section is provided with strip-shaped through holes, which allow airflow to pass through and carry some of the water from the water distribution and humidification section for dispersion and atomization.

[0013] In a further improvement, the vertical height of the water distribution and humidification section is greater than its horizontal width.

[0014] The blade-shaped water distribution and humidification part is vertical, with a raised surface and strip-shaped through holes, which improves the dispersion and atomization effect on the one hand, and increases the amount of dispersion and atomization on the other hand.

[0015] As a further improvement, a drain pipe is provided at the bottom of the ventilation cavity, which is connected to the interior of the ventilation cavity, to discharge water when there is water remaining in the ventilation cavity.

[0016] The application of the technical solution of this utility model has the following technical effects:

[0017] (1) The explosion-proof device in front of the vacuum melting furnace dust collector provided by this utility model is installed in front of the industrial vacuum cleaner to humidify the dust entering the furnace. When the alloy dust in the vacuum melting furnace is vacuumed and removed, the risk of explosion after entering the vacuum cleaner is reduced.

[0018] (2) This utility model uses the rapid airflow generated by the dust suction to disperse and atomize water to humidify dust, instead of relying on the traditional pressurization equipment, thus avoiding the need to set up air compression equipment or pump equipment. It achieves the humidification effect of dispersion and atomization with a simplified structure.

[0019] (3) The blade-shaped water distribution and humidification part of this utility model improves the dispersion and atomization effect and the amount of dispersion and atomization through structural design. Attached Figure Description

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] like Figure 1-5 As shown, the pre-exposed explosion-proof device for the vacuum melting furnace dust collector includes a housing 1. A ventilation chamber 2 is installed inside the housing 1. The ventilation chamber 2 is connected to an inlet pipe 3 and an outlet pipe 4, both extending out of the housing 1. The inlet pipe 3 is used to connect to the flexible hose of the dust collection head, and the outlet pipe 4 is used to connect to an industrial vacuum cleaner. A water storage tank 5 is installed on the top of the housing 1. The water storage tank 5 is connected to a water distribution and humidification unit 6 via a pipe with a valve. Where water connection is convenient, the water storage tank 5 can be omitted, and a water supply pipe can be directly connected.

[0040] The air inlet pipe 3 is connected to the water inlet pipe 7, which in turn is connected to the water storage tank 5 and equipped with a valve. The water inlet pipe 7 can be smaller than the air inlet pipe 3. The connection between the air inlet pipe 3 and the water inlet pipe 7 is not a standard T-junction; instead, a water inlet 31 is opened in the wall of the air inlet pipe at the connection point, with the lower part of the water inlet facing the water distribution and humidification section. The water inlet is designed to ensure that most of the water flows onto the surface of the water distribution and humidification section 6, which helps to disperse the water flow left after atomization. The water inlet 31 can be circular, square, or other shapes.

[0041] Under the suction of the industrial vacuum cleaner, the air quickly enters the ventilation chamber 2 through the air inlet pipe 3, blowing away and atomizing the water distributed on the surface of the water distribution and humidification section 6, and mixing with the dust in the ventilation chamber to humidify the dust.

[0042] The main body of the water distribution and humidification section 6 is blade-shaped, with one side surface gradually convex from all sides towards the central axis, and the upper part of this gradually convex side faces the water inlet 31. This shape is conducive to the dispersion and atomization of water.

[0043] The water distribution and humidification unit 6 is installed at the connection between the air inlet pipe 3 and the ventilation cavity 2. The upper and lower ends of the water distribution and humidification unit 6 are fixedly connected to the wall of the air inlet pipe 3. This section of the air inlet pipe, together with the connection part to the air inlet pipe, can be made into a special T-joint for connection and installation during use.

[0044] The water distribution and humidification section 6 is processed with strip-shaped through holes 61. The strip-shaped through holes 61 allow airflow to pass through and carry some of the water from the water distribution and humidification section for dispersion and atomization, which can increase the amount of dispersed and atomized water.

[0045] A drain pipe 8 can also be added at the bottom of the ventilation cavity 2, communicating with the interior of the ventilation cavity 2, to discharge water if it remains inside the ventilation cavity. Figure 6 As shown in the figure, the valve of the drain pipe is not shown.

[0046] The explosion-proof device for the front of the dust collector of the air smelting furnace provided in this embodiment can be mounted on a trolley, or wheels can be added to the bottom for easy movement with an industrial vacuum cleaner. It can also be integrated with an industrial vacuum cleaner to share a mobile frame.

[0047] Usage process:

[0048] Cut off the connecting pipe of the existing industrial vacuum cleaner's suction head. Connect the section with the suction head to the air inlet pipe 3, and connect the other end to the air outlet pipe 4. Fill the water tank 5 with water. Turn on the industrial vacuum cleaner and open the valve on the water inlet pipe 7 to supply water. This allows for the humidification of alloy dust before it enters the industrial vacuum cleaner when vacuuming and removing it from the vacuum melting furnace, reducing the risk of explosion after entering the vacuum cleaner.

[0049] In this embodiment, the rapid airflow generated by the suction gas is used to disperse and atomize the water to humidify the dust, instead of relying on the traditional pressurization equipment. This avoids the need for air compression equipment or pump equipment, and achieves the humidification effect of dispersion and atomization with a simplified structure.

[0050] In this embodiment, the structural design of the water distribution and humidification section can both satisfy the effect of water dispersion and atomization and increase the amount of dispersion and atomization.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
