Abstract

The utility model discloses a visible flame path manhead for a tank calcinator. The visible flame path manhead for the tank calcinator is characterized in that a flame path manhead (3) capable of rotating in a certain angle range is mounted on a flame path hole seat (1) by a pin shaft (2); temperature resistant glass (4) is fixed on the flame path manhead (3) by a fastener (5); the gap between the flame path manhead (3) and the temperature-resistant glass (4) is sealed by a first sealing part (6); the gap between the flame path manhead (3) and the flame path hole seat (1) is sealed by a second sealing part (7). By adopting the structure, an operator can directly monitor the temperature, negative pressure and the burning condition of volatile components in a flame path on a polling passage, so the workload of the operator is reduced, the damage to a negative pressure system of the calcinator in the uncovering process is reduced, and the calcinator in normal production can be positioned in a better sealing state.

Description

The visual quirk port lid of can-type calcine furnace

Technical field

The utility model belongs to carbon product production field, and especially the can-type calcine furnace of calcination process, need to carry out the artificial quirk peep hole monitoring to temperature, negative pressure, fugitive constituent combustion case etc. in can-type calcine furnace quirk.

Background technology

Fast development along with aluminium industry, improve year by year with demand and the quality of anode of the closely-related prebaked anode of aluminium industry, and prebaked anode is produced the quality of required main raw material petroleum coke in decline year by year, it due to petroleum coke, is particularly the byproduct of crude oil refinery, crude oil refinery industry is mainly pursued the value of high oil refining major product and is adopted new technique, the powder coke content of the byproduct raw petroleum coke of oil refining is constantly increased, add the minimizing due to sweet crude, the sulfur content that makes raw petroleum coke is cumulative year after year also.In order to make the production technology of pre-baked anode for aluminum adapt to the deteriorated needs of raw petroleum coke as far as possible, first important procedure calcination process in prebaked anode production process is used can-type calcine furnace can solve preferably the problem that powder coke content content is high, and therefore can-type calcine furnace is subject to special attention on prebaked anode production line at present.Adopt in addition can-type calcine furnace also can make the carbonaceous of raw petroleum coke in calcination process reduce, be applicable to the requirement of current low-carbon economy.But use can-type calcine furnace because it is comprised of the very many little production units " tank " of quantity, each tank production capacity hourly only has 80-120kg, and in each production unit tank, to carry out the monitoring such as temperature, negative pressure, fugitive constituent burning, if all adopt the control system of automation, the expense of control system is unaffordable.Therefore the peep hole that each factory is all mainly arranged on pot type burner by manual type utilization at present carries out artificial monitoring and Artificial Control to the process system in quirk.Original peep hole must be by manually port lid being opened just and can be seen situation in stove, and the process of opening bell is also the temperature to stove, the process that negative pressure system is destroyed, so should not observe continually operation in operating process.In addition owing to adopting ironcasting between handhole cover and peep hole seat, can not seal well between the two, and peep hole quantity on each production unit " tank " is more, it is the principal element that causes stove to leak out, add leaking out of other places, be very easy to cause the vicious circle of the stove process system that the negative pressure deficiency of stove causes.The process of uncapping also may cause the outer spray of high-temperature flue gas in the original quirk in barotropic state and hurt sb.'s feelings.

Summary of the invention

The technical problems to be solved in the utility model is: for above-mentioned pot type burner, because the stove negative pressure system that manual operation causes is destroyed and reduces manually-operated labour intensity, original can-type calcine furnace quirk port lid is improved.

Technology contents of the present utility model: a kind of visual quirk port lid structure of can-type calcine furnace, on the seat of quirk hole, by bearing pin, installing can be at the quirk port lid of certain angle scope rotation, on quirk port lid, by fixture, heatproof glass is fixed, and by a seal by the gap sealing between quirk port lid and heatproof glass, by No. two seals by the gap sealing between quirk port lid and quirk hole seat.

The beneficial effects of the utility model:

Because various peep holes on can-type calcine furnace are more, adopt after this visible observation port lid, can make originally often need to take off lid and poorly sealed port lid all in good sealing state, make temperature, the negative pressure system of stove maintain good state, can make the total negative pressure of flue reduce, and the power consumption of smoke evacuation system is reduced, the flue-gas temperature that can make in addition stove exit improves and is more conducive to the utilization of waste heat.

Accompanying drawing explanation

Fig. 1 structural representation of the present utility model;

Fig. 2 side view of the present utility model.

The specific embodiment

Structure after improvement is shown in Fig. 1 and Fig. 2, on the seat of quirk hole, 1 installs the quirk port lid 3 that can rotate in certain angle scope by bearing pin 2, by fixture 5, heatproof glass 4 is fixing on quirk port lid 3, and by a seal 6 by the gap sealing between quirk port lid 3 and heatproof glass 4, by No. two seals 7 by the gap sealing between quirk port lid 3 and quirk hole seat 1.Under normal circumstances, can directly by heatproof glass 4, complete the supervision to temperature, negative pressure and volatile combustion situation in quirk, without opening quirk port lid 3, now each peep hole of stove, all in good sealing state, can maintain temperature, the negative pressure system of stove preferably.When needs the operation such as clear up to quirk, still can carry out conventional operation by opening quirk port lid 3.

Can change the handhole cover of each layer of quirk crucial on can-type calcine furnace into this novel visual structure, as the peep hole of one, two, four, eight layer of quirk etc.The port lid of some industry control drillings also can change this new structure into, as volatile matter is controlled arm-tie, air arm-tie, negative pressure control arm-tie etc.

Claims

1. the visual quirk port lid structure of a can-type calcine furnace, it is characterized in that: can be at the quirk port lid (3) of certain angle scope rotation upper the installation by bearing pin (2) of quirk hole seat (1), upper by fixture (5), heatproof glass (4) is fixing at quirk port lid (3), and by a seal (6) by the gap sealing between quirk port lid (3) and heatproof glass (4), by No. two seals (7) by the gap sealing between quirk port lid (3) and quirk hole seat (1).
