Abstract

The utility model discloses a dust removing structure for an industrial heat treatment furnace, which comprises a draft fan, an air flue and a filtering chamber. An exhaust pipe is arranged at the top of the filtering chamber, and an ash dropping bucket is arranged at the bottom of the filtering chamber. More than one pulse filtering bag is arranged in the filtering chamber, more than one pulse valve is arranged outside the filtering chamber, and one pulse valve is communicated with one pulse filtering bag. The upper portion of each pulse filtering bag is communicated with the exhaust pipe, the lower portion of each pulse filtering bag is communicated with the ash dropping bucket, one end of the air flue is communicated with the ash dropping bucket, and the other end of the air flue is used for being connected with the top of a material outlet of an annealing furnace. The draft fan is located in the air flue and blows air into the filtering chamber at the upper portion of the ash dropping bucket through the air flue. The dust removing structure for the industrial heat treatment furnace has good dust cleaning effect, high purifying efficiency, large processed air quantity, small maintenance workload, safe and reliable operation, compact structure, small occupied area, tight entirety and attractive appearance. In addition, the filtering bag has long service life.

Description

Industry heat treatment furnace dedusting structure
Technical field
The utility model relates to a kind of continous way foundry goods lehre dust removal installation.
Background technology
Domestic existing continous way foundry goods annealing does not have dust removal installation, and is very big to factory's surrounding enviroment pollution, seriously influenced workman's physical and mental health, and enterprise has been caused certain economy of energy loss, caused the serious environmental pollution socially yet.
Summary of the invention
The technical problem that the utility model will solve is that existing industrial heat treatment furnace equipment does not have dust removal installation, contaminate environment, is detrimental to health.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: continous way foundry goods lehre dedusting structure, comprise vacuum fan, air channel and filtration chamber, and said filter chamber top is provided with exhaust duct, and the bottom is provided with ash dropping hopper; Establish more than one pulse filter bag in the filtration chamber, the more than one pulse valve of peripheral hardware, and a pulse valve is communicated with a pulse filter bag; Said pulse filter bag top is communicated with exhaust duct, and the bottom is communicated with ash dropping hopper; Said air channel one end is communicated with ash dropping hopper, and the other end is used to connect the top of lehre discharge port, and vacuum fan is positioned at the air channel, and through the air channel wind is blown in the filtration chamber on ash dropping hopper top.
The utility model is installed in the top of continous way foundry goods lehre discharge port; Dusty gas in the stove is being sent in the process of filtration chamber through vacuum fan; Thicker particle directly falls in the ash dropping hopper; Lighter dusty gas filters through the pulse filter bag, and the dust detention is on the pulse filter bag, and pure qi (oxygen) enters atmosphere through exhaust duct; Pulse valve is used for jetting deashing in the pulse filter bag, makes attached to the dust on the filter bag to drop in the ash dropping hopper rapidly.
As a kind of improvement project of the utility model, the ash discharge passage is established in said ash dropping hopper bottom, and the ash discharge passage is provided with ash-valve.The ash-valve time opening is discharged the dust stratification in the ash dropping hopper.
The utility model ash-removal effect is good, purification efficiency is high, it is big to handle air quantity; Life-span of the filter bag is long; Maintenance load is little, safe and reliable to operation, compact construction, floor space is little, integral body is tight, and is handsome in appearance, receives good effect to improving the environment air conservation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model comprises vacuum fan 1, air channel 2 and filtration chamber 3, and 3 tops, said filtration chamber are provided with exhaust duct 6, and the bottom is provided with ash dropping hopper 4; Establish more than one pulse filter bag in the filtration chamber 3,5, one pulse valves of the more than one pulse valve of peripheral hardware 5 are communicated with a pulse filter bag; Said pulse filter bag top is communicated with exhaust duct 6, and the bottom is communicated with ash dropping hopper 4; Said air channel 2 one ends are communicated with ash dropping hopper 4, and the other end is used to be communicated with the top of lehre discharge port, and vacuum fan 1 is positioned at air channel 2, and wind is blown in the filtration chamber 3 on ash dropping hopper 4 tops through air channel 2; Ash discharge passage 9 is established in said ash dropping hopper 4 bottoms, and ash discharge passage 9 is provided with ash-valve 10.
During use, the discharge port top of lehre 8 is communicated with air channel 2, and the dusty gas that vacuum fan 1 will be placed with in the lehre 8 that contains husky workpiece 7 is blown into filtration chamber 3 from bottom to top; In this process; Thicker particle directly falls into 4 li of ash dropping hoppers when the top of process ash dropping hopper 4, thinner dusty gas continues upwards to filter through the pulse filter bag; The dust detention is on the pulse filter bag, and pure qi (oxygen) enters atmosphere through exhaust duct 6.
Operator make program control instrument setting pulse valve 5 open pulse valve 5 one by one through setting-up time rly. output signal; Jetting deashing in the pulse filter bag that is attached thereto; Filter bag is expanded suddenly, under the effect of back draught, invest dust on the cloth bag and hightail filter bag and fall into ash dropping hopper 4.Ash-valve 10 timing opens are discharged the dust stratification in the ash dropping hopper 4 from ash discharge passage 9.

Claims (2)

1. industrial heat treatment furnace dedusting structure is characterized in that: comprise vacuum fan, air channel and filtration chamber, said filter chamber top is provided with exhaust duct, and the bottom is provided with ash dropping hopper; Establish more than one pulse filter bag in the filtration chamber, the more than one pulse valve of peripheral hardware, and a pulse valve is communicated with a pulse filter bag; Said pulse filter bag top is communicated with exhaust duct, and the bottom is communicated with ash dropping hopper; Said air channel one end is communicated with ash dropping hopper, and the other end is used to connect the top of lehre discharge port, and vacuum fan is positioned at the air channel, and through the air channel wind is blown in the filtration chamber on ash dropping hopper top.
