Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic dust cleaning systems, in particular to a double-track device for a hydraulic dust cleaning system. Background Art

[0002] Waste incineration waste heat boiler flue gas contains high chloride ion content and has a low ash melting point. At flue gas temperatures between 850°C and 500°C, coking easily forms on the boiler's water-cooled walls, reducing their heat absorption capacity. This causes flue gas temperatures entering the superheater or evaporator in the horizontal flue to reach over 650°C, leading to coking and clogging in the superheater or evaporator area. This, in turn, causes high-temperature corrosion in the superheater or evaporator, impacting the boiler's safety and economic efficiency. Conventional steam or shock wave cleaning methods are difficult to remove. To address this problem, hydraulic cleaning has emerged, specifically for online cleaning of slagging and coking in the water-cooled walls of the secondary and tertiary flues of waste incineration boilers. It is highly effective in removing coke. The boiler's vertical flue has a rectangular horizontal cross-section, with several cleaning guide holes in the furnace roof. The cleaning equipment nozzle enters the flue through the guide holes, spraying an umbrella-shaped spray (circular when viewed from above). The nozzles sequentially enter and exit the holes, ensuring that the resulting umbrella-shaped spray pattern covers the entire water-cooled wall. The hydraulic cleaning system is located between the furnace's top beam and the roof. The hydraulic cleaning unit must be moved between the various cleaning guide holes, allowing the water nozzles to enter and exit the furnace through the guide tubes. Therefore, equipment that can move the hydraulic cleaning unit longitudinally and transversely is required. Currently, dual-track equipment is the mainstream method for arranging multiple rows of hydraulic cleaning points for waste heat incineration boilers.

[0003] However: In the existing technology, the upper traveling motor is usually located at the end, and the connecting shaft between the traveling box A and the traveling box B of the upper two traveling tracks is long and easy to deform. Originally, the gears of the two traveling boxes are meshed with the racks on the tracks synchronously. If the connecting shaft is deformed, the two traveling boxes will not be able to run synchronously, affecting the use of the equipment. Therefore, a double-track device of the hydraulic cleaning system is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a double-track device for a hydraulic dust cleaning system in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The dual-track device of the hydraulic dust cleaning system includes three primary and secondary support beams.

The upper running motor is a double-headed motor, with its front and rear output ends fixedly connected to opposite ends of the two first transmission shafts via couplings. An upper positioning encoder is installed at the end of the connecting shaft of the running box A. The upper running rails and rollers limit the left and right movement of the two running boxes A.

[0009] Preferably, a mounting bracket is fixedly connected to the bottom of the traveling box B, and the mounting bracket is arranged at the bottom of the first track support beam. The hydraulic dust cleaning host is installed by arranging the mounting bracket.

[0010] Preferably, the left and right ends of the first track support beam are fixedly connected to second track support beams, the number of the second track support beams is two, and the first track support beam and the second track support beam are arranged perpendicularly. The first track support beam and the second track support beam provide support force for the movement of the hydraulic dust cleaning main unit.

[0011] Preferably, the bottom ends of the two second track support beams are respectively fixedly connected with two support legs, and the two support legs are respectively arranged at the lower left corner and the lower right corner of the second track support beam.

[0012] Working principle: Install the hydraulic dust cleaning host to the bottom of the travel box B through the mounting bracket, turn on the upper travel motor to drive the first transmission shaft to rotate, the rotation of the first transmission shaft drives the first gear to rotate, the rotation of the first gear drives the lower travel track, travel box B, mounting bracket, and hydraulic dust cleaning host to move left and right through the first rack and roller, turn on the lower travel motor to drive the second transmission shaft to rotate, the rotation of the second transmission shaft drives the second gear to rotate, the rotation of the second gear drives the travel box B, mounting bracket, and hydraulic dust cleaning host to move forward and backward through the second rack and roller, thereby freely controlling the moving position of the hydraulic dust cleaning host in the horizontal direction.

[0013] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. The upper travel motor is located between the two track beams, which shortens the length of the connecting shaft between the two travel boxes and reduces the probability of deformation of the connecting shaft.

Even if the motor gear box slips, it will not affect the normal counting of the encoder and the position positioning of the hydraulic dust cleaning host will not be affected.
