Example Embodiment

[0027] The structure of the mechanical dust removal device for the thermal medium furnace of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] See Figure 1a , 1b , The figure shows the cleaning device of the present invention which is cleaning the inner wall of the heat medium furnace. 10 is the body of the ash cleaning device, 90 is the spiral coil on the inner wall of the heat medium furnace, the spiral coil 90 is welded by seamless carbon steel pipes, and the entire furnace body is a horizontal cylinder. As shown in the figure, the ash cleaning device body 10 is placed on the outside of the furnace mouth 80 of the heat medium furnace, and the telescopic arm system 30 carries the dust removal brush 20 from the furnace mouth 80 of the heat medium furnace into the furnace to clean the ash. In the process of extending into the furnace bottom and retracting, the dust removal brush 20 rubs against the furnace wall by rotati...

Abstract

The invention discloses a mechanical ash removing device for a heat medium furnace, which comprises a machine base, a telescopic arm supported by the machine base and capable of flexing forwards and backwards, a decelerating motor arranged at the front end of the telescopic arm, and an ash-removing descaling brush arranged on the output shaft of the decelerating motor and used for removing ash scales on the inner wall of the heat medium furnace. While working, the ash-removing descaling brush is contacted with the inner surface of the furnace wall of the heat medium furnace and performs rotary motions along the inner peripheral surface of the furnace wall. The mechanical ash removing device for the heat medium furnace can clear the cokes in the furnace wall of the heat medium furnace and the grime formed on the outer surface of a heat pipe, can greatly lighten the labor intensity for ash removing and reduce the damage caused by the ash removal work to the body of a worker, has higher ash removal efficiency than that of the worker, can solve the problem of periodical sweeping of the widely applied heat medium furnace and achieve the automation of sweeping, and can reduce environmental pollution.

Description

technical field [0001] The invention relates to a dust removal and scale removal device, in particular to a mechanical dust removal device for a heat medium furnace used in the crude oil transportation process. Background technique [0002] Crude oil pipelines are densely distributed all over the country. In order to solve the difficulty of transporting crude oil with high freezing point and high sodium content, it is necessary to provide kinetic energy and thermal energy to crude oil. For this reason, heat medium furnaces are widely used in the process of crude oil transport. At present, the main heating process is to use oil (gas) as fuel and heat transfer oil as heat carrier. The fuel burns in the furnace through the burner to generate heat, and the heat is transferred to the heat transfer oil through the heat transfer tube in the form of convection and radiation. Driven by the circulation pump, the heat is taken away through the outlet of the heat medium furnace, and aft...
