Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, an air filter that glass tempering furnace was used, including protecting crust 1, the upper and lower ends of protecting crust 1 communicate respectively has intake pipe 2 and outlet duct 3, and protecting crust 1 is equipped with purification filter core 8, it is equipped with sleeve 9 to inlay on the purification filter core 8, and sleeve 9 internal seal sliding connection has ejector pin 10, ejector pin 10 lower extreme fixedly connected with sealing plug 4, and the lateral wall of sealing plug 4 has seted up T type groove 5, install the pushing mechanism who promotes ejector pin 10 and remove in the protecting crust 1, recess 6 has been seted up on the inner wall of protecting crust 1, install communicating blast pipe 15 rather than inside on the protecting crust 1, fixedly connected with support 13 on the sealing plug 4, and support 13 keeps away from sealing plug 4 one end fixedly connected with closing plate 14. It should be noted that, a one-way stop valve is installed in the exhaust pipe 15, and the one-way stop valve enables air to flow only from the inside of the protective shell 1 to the exhaust pipe 15 in one way, so that when the device inhales air, the air is prevented from directly entering the device from the exhaust pipe 15 without being filtered by the purification filter element 8.

Pushing mechanism is including rotating the deep bead 12 of connection on 1 inner wall of protecting housing, and deep bead 12 is close to intake pipe 2 and sets up, and deep bead 12 rotates with ejector pin 10 through connecting rod 11 to be connected, and connecting rod 11 one end rotates with ejector pin 10 to be connected, and the connecting rod 11 other end rotates with deep bead 12 to be connected.

The wind deflector 12 is connected to the inner wall of the protective shell 1 by a spring 7. 1 upper end fixedly connected with storage water tank 16 of protecting crust, the water filling port has been seted up to the upper end of storage water tank 16, and the lateral wall of protecting crust 1 has seted up spout 21, and the sealed sliding connection has burette 20 in the spout 21, and the sealed on the burette 20 runs through the storage water tank 16 in the bottom and extends to in the storage water tank 16. The drip tube 20 is sealingly slidably disposed in the slide groove 21, so that the slide groove 21 can be sealed without air leakage. Furthermore, the diameter of the dropper 20 is small, so that water in the water storage tank 16 can drop downwards in a drop shape when flowing downwards through the dropper 20, the contact area between the water and the exhaust pipe 15 can be greatly increased, and when high-temperature flue gas is discharged by the exhaust pipe 15, the dropped water drops can be rapidly gasified and evaporated.

The inner wall of the protective shell 1 is provided with a driving groove 18, and the driving groove 18 is arranged at the upper side of the purification filter element 8. A gear 17 is rotationally connected in the driving groove 18, the gear 17 is fixedly connected with the wind deflector 12, a rack 19 meshed with the gear 17 is slidably connected in the driving groove 18, and a dropper 20 is fixedly connected to the side wall of the rack 19. It should be noted that, by providing the dropper 20, when the exhaust pipe 15 discharges high-temperature flue gas, water in the water storage tank 16 can drop to the outer wall of the exhaust pipe 15 to evaporate and absorb heat, so as to cool the air filtering device.

In the use process of the invention, under the initial state, the positions of all parts of the device are shown in the position of figure 3, and because the exhaust pipe 15 is internally provided with the one-way stop valve, when the induced draft fan in the glass tempering furnace is started, the induced draft fan continuously sucks air from the air outlet pipe 3 and cannot suck air from the exhaust pipe 15 inwards, so that the sealing plug 4 is moved downwards. And until the T-shaped groove 5 moves to the groove 6, and the upper part of the groove 6 is exposed above the sealing plug 4 (as shown in fig. 1), at this time, air can enter from the air inlet pipe 2, is filtered by the purifying filter element 8, and then flows to the air outlet pipe 3 through the groove 6 and the T-shaped groove 5 (the air flow direction is shown by a hollow arrow in fig. 1).

When air flows in from the air inlet pipe 2, the air flow pushes the wind shield 12 to rotate downwards, so that the ejector rod 10 can be pushed to move downwards through the connecting rod 11, the ejector rod 10 continues to push the sealing plug 4 to move downwards for a certain distance, the exposed area of the groove 6 is increased, and the air inlet efficiency is improved. In addition, when the push rod 10 pushes the sealing plug 4 to move downwards, the support 13 is also driven to move downwards, and the sealing plate 14 on the right side of the support 13 plugs the air inlet end of the exhaust pipe 15, so that air in the protective shell 1 is prevented from being discharged outwards through the exhaust pipe 15 to generate air leakage.

After the glass is calcined and the internal draught fan of the toughening furnace is closed, the negative pressure in the air outlet pipe 3 disappears, at the moment, the spring 7 pulls the wind shield 12 to rotate upwards for resetting, and the wind shield 12 pulls the ejector rod 10 to move upwards for resetting through the connecting rod 11. The push rod 10 will pull the sealing plug 4 to move upwards to restore to the initial state of fig. 4. At the moment, the T-shaped groove 5 is communicated with the exhaust pipe 15, and the high-pressure and high-temperature flue gas in the furnace can enter the protective shell 1 through the exhaust pipe 3, enter the exhaust pipe 15 from the T-shaped groove 5, and is discharged to the atmosphere after being sent into corresponding flue gas treatment equipment for treatment.

It should be noted that, by arranging the sealing plug 4, the T-shaped groove 5, the exhaust pipe 15, the pushing mechanism and other parts, the device can discharge high-temperature flue gas in the furnace from the exhaust pipe 15 after the internal draught fan in the glass tempering furnace is closed, compared with the technical means of directly preventing the flue gas from entering the air filtering device by arranging the one-way valve or similar structure, the device can actively send high-pressure and high-temperature flue gas in the furnace into corresponding flue gas processing equipment through the exhaust pipe 15 for processing, can effectively perform pressure reduction processing on the inside of the glass tempering furnace, and prevent dangerous accidents such as explosion.

It should be noted that, when the induced draft fan in the glass tempering furnace is turned on, as can be seen from the above, the structure of each component of the device is in the state shown in fig. 1, at this time, the wind shield 12 rotates downward, so as to drive the gear 17 to rotate counterclockwise, thereby pushing the rack 19 to move upward, the rack 19 will drive the dropper 20 to move upward, at this time, the upper end of the dropper 20 is located above the liquid level in the water storage tank 16, and then the water in the water storage tank 16 cannot drop downward through the dropper 20.

When the induced draft fan in the glass tempering furnace is started, it can be known from the above that the structures of the components of the device are in the states shown in fig. 3, the wind shield 12 rotates upwards at the moment, so the gear 17 can be driven to rotate clockwise, thereby the rack 19 is pushed to move downwards, the rack 19 drives the dropper 20 to move upwards, at the moment, the upper end of the dropper 20 is submerged into the bottom in the water storage tank 16 and is positioned below the liquid level in the water storage tank 16, then the water in the water storage tank 16 drops downwards through the dropper 20, the water drops dropping from the dropper 20 drop through the chute 21 fall on the outer wall of the exhaust pipe 15, because the contact area of the water drops and the outer wall of the exhaust pipe 15 is large, the heat of the smoke flowing in the exhaust pipe 15 can be rapidly absorbed and evaporated, thereby the smoke in the exhaust pipe 15 is pushed to be cooled, so the damage to the air filtering device caused by the high temperature of the smoke can also be avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
