Abstract
The utility model relates to a graphite lubrication sheet steel sealing device which uses for the connection point between the combustion furnace and the dryer. The utility model comprises a circle of the sheet steels group connected with a sealing fixing container and a rotation container, in particular to a graphite lubrication device is arranged on a circle of the sheet steels group at least. The device is provided with a machine base, the machine base is fixed with the sheet steel, the machine base is designed with a graphite chamber to place a graphite block, a through hole is provided with the sheet steel over against the graphite, and the machine base is also provided with a spring which presses the graphite block downwards to seal and lubricate. The utility model has the advantages of simple structure, low cost, and good sealing effect, can decrease the heat dissipation, and can improve the heat efficiency of the system. The graphite lubrication sheet steel sealing device can widely used for the burning and drying system in the industry.
Description
(1) technical field: the utility model relates to the seal arrangement in the industrial combustion drying system, especially for a kind of graphite lubrication steel disc seal arrangement of combustion furnace and dryer joint.
㈡ background technique: in the industrial combustion drying system, for stoping cool air to enter the reduction thermal efficiency, increase the air inducing power consumption that gathers dust, or stop hot gas to overflow the minimizing thermal loss, joint at combustion furnace and dryer, all to adopt various forms of sealings, as maze type, steel disc formula, also can adopt super heated rubber formula etc. below 300 ℃, more several forms, wherein better with the steel disc formula: (1) selects different material manufacturings, and it is fragile to bear 100～1000 ℃ of medium temperatures, can keep sealing effect; (2) can compensate the kiln system and make the swing that error causes, keep sealing effect; (3) air leak rate of air curtain is low; (4) in light weight, cost is low, is convenient to make.But this structure must add pretightening force when installing or around last steel cable, and keeping and the contacting of cylindrical shell, the lubricated anti-attrition under high temperature condition between seal steel plate and the cylindrical shell like this becomes major issue.As not good lubricated anti-attrition device, the wearing and tearing of steel disc are big, and sealing effect is poor.
The ㈢ summary of the invention: the purpose of this utility model is to solve the problem that existing steel disc formula sealing configuration exists, and a kind of graphite lubrication steel disc seal arrangement of lubricated anti-attrition is provided.
The utility model is to improve at existing steel disc formula sealing configuration to form, it includes the steel disc group that a circle connects sealing and fixing tube and rotary drum equally, its improvement is: on a circle steel disc group graphite lubrication device is housed at least, this device has support, support and steel disc fixed installation, design has the graphite chamber to place graphite block on the support, and steel disc has through hole over against the graphite place, spring also is housed on support presses the downward seal lubrication of graphite block.
The spring of adorning on support described in the utility model is time power back-pressure spring that adopts, and it adopts bearing pin to be connected with support.
For the better protect rotary drum, the high-temperature flue gas entry end of the utility model on the rotary drum steel seal ring that has been welded is connected with steel disc again.
The utility model is simple in structure, and cost is low, and good sealing effect can significantly reduce thermal loss, improves system thermal efficiency.
The ㈣ description of drawings:
Fig. 1 is a general structure schematic representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: the 1-stationary magazine creel, 2-steel disc group, 3-graphite lubrication device, the 4-rotary drum, 5-support, 6-bearing pin, 7-return power back-pressure spring, 8-graphite chamber, 9-graphite block, 10-seal ring.
The ㈤ embodiment:
Referring to Fig. 1, Fig. 2, the utility model is for better protect rotary drum 4, and the steel seal ring 10 that at first is welded on rotary drum 4 is installed a circle steel disc group 2 then between stationary magazine creel 1 and seal ring 10.(have the polylith arc steel plate around arrangement, overlapping pre-pressing structure or the ring dress steel cable of adding in steel disc joint forms in twos).On the steel disc therein a graphite lubrication device 3 is housed, this device includes a support 3 and fixedlys connected installation with steel disc 2, and the right-hand member design of support 3 has graphite chamber 8, and graphite block 9 is housed, have through hole over against graphite block 9 places on the steel disc 2, allow graphite block 9 pass and contact with seal ring 10.On support 3, adopt bearing pin 6 to install back power back-pressure spring 7, return power back-pressure spring 7 and press graphite block 9 downward seal lubrications.
Graphite lubrication device 3 in the utility model can also be made so simpler structural type, promptly makes a tubular support, and the graphite block of packing in the tube is installed stage clip on the graphite block, add gland again and get final product.
Claims (3)
1. graphite lubrication steel disc seal arrangement, it includes the steel disc group that a circle connects sealing and fixing tube and rotary drum, it is characterized in that: on a circle steel disc group, a graphite lubrication device is housed at least, this device has support, support and steel disc fixed installation, design has the graphite chamber to place graphite block on the support, and steel disc has through hole over against the graphite place, spring also is housed on support presses the downward seal lubrication of graphite block.
2. graphite lubrication steel disc seal arrangement according to claim 1 is characterized in that: the spring at the support dress is time power back-pressure spring that adopts, and it adopts bearing pin to be connected with support.
