[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a special sealing device for a zinc-containing waste hydrochloric acid regeneration furnace, which solves the problem that the existing sealing device is difficult to replace after being worn.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical scheme: a special sealing device for a zinc-containing waste hydrochloric acid regeneration furnace, comprising a roasting furnace body, a feed hood fixedly connected to the left side of the roasting furnace body, a connecting plate fixedly connected to the right side of the feed hood and the connecting plate is fixedly connected on the outer diameter of the roasting furnace body, a uniformly distributed baffle fixedly connected to the right side of the connecting plate and the baffle is fixedly connected on the outer diameter of the roasting furnace body, a tensioning ear fixedly connected to the top of the left side of the baffle, a welding retaining ring slidably connected to the outer diameter of the roasting furnace body, a clamping plate fixedly connected to the outer diameter of the welding retaining ring, a pressure plate fixedly connected to the left side of the pressure plate and the bottom of the right side of the pressure plate is fixedly connected to the welding retaining ring, a follower roller fixedly connected to the top of the right side of the pressure plate, a uniformly distributed roller seat rotatably connected to the top of the follower roller, and two fixing bolts penetrate and are slidably connected to the roller seat.

[0008] Preferably, a graphite packing is slidably connected to the outer diameter of the roasting furnace body and the graphite packing is located between the baffle and the pressure plate.

[0009] Preferably, the fixing bolts are all threadedly connected with fixing nuts, and the fixing nuts are located on the left side of the tensioning lug.

[0010] Preferably, a spring is provided on the outer diameter of the fixing bolt, and both ends of the spring are in contact with the support leg and the tensioning lug respectively.

[0011] Preferably, one end of the fixing bolt is threadedly connected to the tensioning lug respectively.

[0012] Preferably, one end of the fixing bolt is threadedly connected to the tensioning lug respectively.

[0013] Preferably, the connecting plate, graphite packing and welding retaining ring are all in the shape of hollow rings.

[0014] Preferably, a sealing device dedicated to a zinc-containing waste hydrochloric acid regeneration furnace, the method for using the sealing device comprises the following steps:

[0015] Slide the graphite packing onto the outer diameter of the roasting furnace body, then slide the welding retaining ring onto the outer diameter of the roasting furnace body, and make the pressure plate contact with the graphite packing, then slide the fixing bolt onto the roller seat and turn the fixing bolt to make it threadedly fixed with the tensioning lug, then slide the spring onto the outer diameter of the fixing bolt and the spring is located on the left side of the tensioning lug, then screw the fixing nut onto the fixing bolt to fix the spring;

[0016] When the tension needs to be adjusted, just turn the fixing nut to adjust the tightness of the spring;

[0017] When the graphite packing needs to be replaced, turn the fixing bolts to remove it, then remove the welding retaining ring from the outer diameter of the roasting furnace body and replace it with a new graphite packing.

[0018] Working principle: The baffle and the pressure plate can be pressed against the outer diameter of the roasting furnace body by a tensioning and fastening mechanism composed of two fixing bolts, two fixing nuts and a follower roller, so that the graphite packing fits tightly against the roasting furnace body, thereby ensuring the sealing effect. When the tension needs to be adjusted, the fixing nut can be turned to adjust the tightness of the spring. When the graphite packing needs to be replaced, the fixing bolts can be turned to remove it, and then the welding retaining ring can be removed from the outer diameter of the roasting furnace body, and a new graphite packing can be quickly replaced. The sealing degree can be adjusted and the worn graphite packing can be quickly replaced. In addition, the follower roller can not only press the graphite packing, but also the friction is smaller because the follower roller is a linear contact rolling. Due to the use of the spring tensioning and fastening mechanism, when the roasting furnace body rotates and there is a swing or eccentricity, the sealing device can still fit tightly against the outer diameter of the roasting furnace body.

When the tension needs to be adjusted, the fixing nut can be turned to adjust the tightness of the spring. When the graphite packing needs to be replaced, the fixing bolt is rotated to remove it, and then the welding retaining ring is removed from the outer diameter of the roasting furnace body, so that a new graphite packing can be quickly replaced, and the sealing degree can be adjusted and the worn graphite packing can be quickly replaced. In addition, the follower roller can not only press the graphite packing, but also the friction force is smaller because the follower roller is a line contact rolling. Due to the use of the spring tensioning and fastening mechanism, when the roasting furnace body rotates and there is a swing or eccentricity, the sealing device can still be tightly fitted with the outer diameter of the roasting furnace body. The invention is specially used for the sealing of the waste hydrochloric acid regeneration furnace equipment generated by the galvanizing production line, improves the sealing and adaptability of the regeneration furnace equipment, reduces the leakage of toxic gases generated by roasting, and is worthy of vigorous promotion.
