Abstract
The utility model relates to an exhaust pipe fixing structure for oil fume exhausters, which comprises an air outlet hood for installing the exhaust pipe. A connecting plate is arranged on the air outlet hood and an air outlet of a host machine and is fixed on the air outlet, and the air outlet hood and the connecting plate are connected in a drawable plug-in mode and are fixed with each other in a detachable mode. The utility model has the advantages that the defect of oil leakage caused by the poor combination of a plastic air outlet hood and the air outlet of the air outlet can be overcome, and the drawable plug-in connection bring convenience to the installation and the detachment of the air outlet hood.
Description
The utility model is a kind of exhaust duct fixed structure that is used for lampblack absorber.
The lampblack absorber exhaust duct is to be installed on the air outlet of host shell by outlet housing, and it is the not most toxic emission passage of oil smoke, oil gas and fuel combustion of blower fan suction, requires discharging unobstructed and prevent leakage of oil.The exhaust duct of all kinds of lampblack absorbers connection in the market all is to use the screw in compression structure around adopting the plastics outlet housing, because plastics outlet housing poor rigidity, for preventing leakage of oil, must around outlet housing, use a plurality of screw in compressions, all make troubles for installation and removal, also keep away unavoidable oil leakage phenomenon, make the greasy dirt that is adsorbed on the exhaust duct inwall of deposition dirty, flow and amass at the complete machine top through the gap of outlet housing and air outlet contact-making surface along tube wall.
The purpose of this utility model is to avoid the defective of prior art and provides a kind of installation, the oil tight exhaust duct fixed structure of convenient disassembly to society.
The purpose of this utility model realizes by following scheme: comprise the outlet housing with installation exhaust duct cannelure, outlet housing is fixed on the main frame air outlet, its improvements are that described host shell air outlet is provided with and are fixedly coupled plate, but outlet housing is connected and removable fixing with the plug-in type of connecting plate for pull.
Advantage of the present utility model has been to overcome the oil leakage phenomenon that the plastics outlet housing causes because of poor rigidity, and has reduced mounting screw, has brought convenience to installation and removal.
Description of drawings.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B place enlarged drawing of Fig. 2.
By above-mentioned accompanying drawing embodiment of the present utility model is remake and to elaborate.
Exhaust duct fixed structure (referring to Fig. 1-3) comprises the outlet housing (4) with installation exhaust duct cannelure (7), the bottom land of cannelure is provided with outage (8), plastic outlet housing is connected with host shell (1) by connecting plate (2), connecting plate is fixed on the air outlet (3) of host shell with spot welding or rivet or screw with steel plate or aluminium sheet, the utility model adopts steel plate spot welding to fix, but outlet housing is connected and removable fixing with the plug-in type of connecting plate for pull.
Connecting plate (2) three is worn fluted structure, this groove can match slotting with three limit activities of outlet housing (4), after outlet housing inserts the connecting plate groove, its three besieged, be fastenedly connected with 2 screws (6) in its another side indentation, there (5), when needing dismounting as long as remove 2 screws earlier, but outlet housing just pull come out, easy accessibility has avoided the plastics outlet housing because of combine the bad leakage of oil disadvantage that causes with the main frame air outlet again.
Claims (3)
1. exhaust duct fixed structure that is used for lampblack absorber, comprise and have the outlet housing (4) that exhaust duct cannelure (7) is installed, outlet housing is fixed on host shell (1) air outlet (3), it is characterized in that described main frame air outlet (3) is provided with is fixedly coupled plate (2), but outlet housing is connected and removable fixing with the plug-in type of connecting plate for pull.
2. exhaust duct fixed structure as claimed in claim 1 is characterized in that described connecting plate (2) is three to wear fluted structure, and this groove can match slotting with three limit activities of outlet housing.
