Abstract
The utility model relates to an oil smoke collecting device of a pit type tempering furnace. The oil smoke collecting device comprises a pit type furnace body, a furnace cover and a lifting mechanism which is used for driving the furnace cover to move up and down. The oil smoke collecting device is characterized in that a smoke gathering ring, a flue connecting pipe which is penetrated in a flue mounting hole formed in the ring wall of the smoke gathering ring, and a smoke discharging pipeline which is combined with the flue connecting pipe through a transition connecting pipe and a connecting flange are arranged between the furnace mouth of the pit type furnace and the furnace cover.
Description
Technical field
The utility model relates to the collection technique of the oil smoke that distributes in a kind of tempering heat treatment technology, relates to a kind of cooking fume-collecting device of well formula tempering stove specifically.
Background technology
Workpiece will pass through temper after quenching oil quenches, continue to produce a large amount of oil smoke in the tempered process, causes environmental pollution, the harm health of human body.Generally adopt smoke purifier to purify for the processing of oil smoke, reach satisfied effect and also must carry out effective collection oil smoke.
Cooking fume-collecting at tempering stove adopted dual mode in the past mostly in the prior art:
A kind ofly see shown in Figure 1ly, annular be set receive petticoat pipe that after bell covered, the receipts petticoat pipe that the oil smoke that overflows from the bell edge will be under the negative pressure sucked, and delivered in the clearing machine by pipeline to purify again on bell.This mode has 2 weak points: the one, and the not sealing of circular cowling below, oil smoke leaks more; The 2nd, to move toward top and side when bell is opened, between movement pipeline and the restrained line engage and there is certain problem in sealing.
Another kind is seen shown in Figure 2, opens an osculum near the bell outside, adopt joint and flexible pipe and fixedly hard tube link.The weak point of this mode: the one, opening must be located between Muffle pot and the bell thermal insulation layer, and because the space is narrow and small, opening is less, causes centrifugal blower suction to weaken, and exhaust smoke level is subjected to certain influence, and bell edge oil smoke leaks more; The 2nd, when opening bell, flexible pipe need pull out at every turn, brings inconvenience, and influences the sealing of interface.
Summary of the invention
The purpose of this utility model provides a kind of cooking fume-collecting device of well formula tempering stove just at existing weak point in the above-mentioned prior art.
The purpose of this utility model can realize by following technique measures:
Cooking fume-collecting device of the present utility model comprises pit furnace body of heater, bell and is used to drive the hoisting appliance that bell is made the upper and lower shifting movement; Between pit furnace fire door and bell, be provided with smoke-accumulating ring, be installed on the flue pipe connecting in the flue open holes that processes on the smoke-accumulating ring circle wall, the smoke discharging pipe that combines with the flue pipe connecting by transition adapter and joint flange.
Smoke-accumulating ring upper/lower terminal described in the utility model is a flange arrangement, the upper surface of upper flange is processed with sealing groove, adopt asbestos packing and bell to seal, packing_seal circle on lower flange and the lower end fire door seals, and is filled with the asbestos plate that is used for heat-insulation and heat-preservation in the annular groove between upper and lower flange.
The beneficial effects of the utility model are as follows:
The utility model is because all members have all adopted and have been fixedly connected, and compact construction does not have movement pipeline, need not dismantle and movement pipeline when opening at bell, thereby realized good sealing effectiveness, reduced the leakage of oil smoke, and do not influenced workpiece dress, the lifting of coming out of the stove.
Description of drawings

Sequence number among Fig. 1: the 1st, the pit furnace body of heater, the 2nd, smoke discharging pipe, the 3rd, portable smoke discharging pipe, the 4th, annular is received petticoat pipe, the 5th, bell.
Fig. 2 is available technology adopting joint and flexible pipe and the fixing joining synoptic diagram of hard tube.
Sequence number among Fig. 2: the 1st, the pit furnace body of heater, the 2nd, smoke discharging pipe, 3-1 are detachable smoke discharging pipes, 4-1 is a hose nipple, the 5th, bell.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is that the master of smoke-accumulating ring cuts open figure among Fig. 3.
Fig. 5 is the vertical view of Fig. 4.
Sequence number among Fig. 3,4,5: the 1st, the pit furnace body of heater, the 2nd, smoke discharging pipe, 3-2 are adapter bonnets, 4-2 is the flue pipe connecting, the 5th, bell, the 6th, smoke-accumulating ring, the 7th, upper flange, the 8th, lower flange, the 9th, the annular groove between the upper and lower flange.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 3, cooking fume-collecting device of the present utility model comprises pit furnace body of heater 1, bell 5 and is used to drive the hoisting appliance that bell 5 is done the upper and lower displacement campaign; Between pit furnace fire door and bell, be provided with smoke-accumulating ring 6, be installed on the flue pipe connecting 4-2 in the flue open holes that processes on the smoke-accumulating ring circle wall, take over the smoke discharging pipe 2 that 3-2 and joint flange combine with the flue pipe connecting by transition.
Shown in Fig. 4,5, smoke-accumulating ring upper/lower terminal described in the utility model is a flange arrangement, the upper surface of upper flange 7 is processed with sealing groove, adopt asbestos packing and bell 5 to seal, packing_seal circle on lower flange 8 and the lower end fire door seals, and is filled with the asbestos plate that is used for heat-insulation and heat-preservation in the annular groove 9 between upper and lower flange.
Because the utility model has adopted smoke-accumulating ring 6 has been set between pit furnace fire door and bell, and the mode that is connected with adapter bonnet 3-2, smoke discharging pipe 2 by the flue pipe connecting 4-2 that installs on the smoke-accumulating ring feeds the smoke purifier inlet with oil smoke, this also just makes all collection cigarette members be and is fixedly connected, in the furnace cover lifting process, need not move, dismantle, and reach by the sealing material that interface adds and to prevent the effect of leaking gas.
