Automatic ash removing device of concentration type curing-house radiator

Abstract

The invention relates to a device capable of automatically removing dust of radiating pipes in an intensive roasting room, belonging to the technical field of tobacco preparing equipment. The invention is composed of an actuating motor (1), a vertical screw rod (2), a parallel screw rod (3), a dust cleaner (4) and a controller, wherein, a, the dust cleaner (4) is formed by combining two cones from the underside direction, and one parallel screw rod (3) is fixed through the peak of one cone; b, the dust cleaner (4) is in a fire storeroom outside the radiating pipes and enters the radiating pipes to clean dust at certain interval; c, under the effect of the actuating motor (1),the vertical screw rod (2) drives the parallel screw rod (3) and the dust cleaner (4) to move left and right so as to clean dust; d, the controller uses a PI or a PID to control and shares the same chip with a controller of the roasting room; setting parameters of dust cleaning intervals are set in a display. The invention has advantages of a simple structure, a low construction cost, a convenient operation and an energy saving property, and can be widely applied to metal radiating pipes in an intensive roasting room.

Description

Technical field: [0001] The invention relates to a device capable of automatically cleaning the dust of heat-dissipating pipes of intensive barns, and belongs to the technical field of flue-cured tobacco preparation equipment. Background technique: [0002] The research and application of intensive barns in China has achieved rapid development since 2003. Practice has proved that intensive curing barns have incomparable advantages over ordinary barns, and can significantly or extremely significantly increase the quality and income of tobacco leaves during the curing process; it is a revolutionary change in the reform of barns; Production, professional baking, and promoting the transformation of traditional tobacco agriculture to modern tobacco agriculture have a huge role in promoting. [0003] During the popularization and application of intensive barns, a prominent problem of "dust accumulation affecting heat exchange" or "dust accumulation blocking" has emerged in recen...

AI Technical Summary

Problems solved by technology

[0004]①The diameter of the cooling pipe is small, such as 114mm in diameter, 121mm in diameter, 130mm in diameter, and 140mm in diameter. It is difficult to heat up when the door is full of smoke; when the door is opened, it can be seen that there is a lot of dust on the inner wall of the heat dissipation pipe, which seriously hinders the normal operation of the smoke flow and greatly reduces the heat dissipation efficiency

[0005]②The diameter of the cooling pipe is relatively large, such as 165mm in diameter and 219mm in diameter. During the curing process of tobacco leaves, the temperature in the tobacco chamber is above 45°C, and the fire is normal, but it is difficult to heat up. It costs more coal; when you open the dust removal door, you can see that there is a lot of dust on the inner wall of the heat dissipation pipe, and the flue gas flow can pass through normally, but the heat dissipation effect is not good

[0007] Overseas, the intensive drying room has been popularized and applied for more than 50 years, but the problem of "dust accumulation affecting heat exchange" or "dust accumulation blockage" still exists

[0008] Through literature search, there is no public report identical with the present invention
