Further, in the above technical solution, one end of each sand baffle is fixedly disposed on the inner walls of the air inlet pipeline and the air outlet pipeline, and the other end of each sand baffle is obliquely disposed toward the lower portion in an inverted cone shape; the sand can be well resisted in the machine equipment through the sand baffle plate, and the leakage is avoided.
Further, in the above technical solution, the sand baffles on the inner walls of the air inlet pipeline and the air outlet pipeline are staggered up and down; the moving distance of the sand grains is prolonged by the staggered arrangement, the kinetic energy is reduced, and the sand grains can freely fall.
Further, in the above technical solution, the free ends of the sand baffles all extend to the central axis of the air inlet pipeline and the air outlet pipeline; avoid the sand grains to penetrate out from the sand baffle plates.
Further, in the above technical solution, a first air inlet is disposed at an upper end of the air inlet pipeline, and a first air outlet is disposed at one side of a lower end of the air inlet pipeline; the induced draft operation can be effectively carried out.
Further, in the above technical solution, the first air inlet is further provided with a filter screen in an embedded manner; prevent external dust, impurities and the like from entering the machine equipment.
Further, in the above technical solution, a second air outlet is fixedly disposed at the upper end of the air outlet pipe; a second air inlet is also formed in one side of the lower end of the air outlet pipeline; such a design may achieve its air extraction effect.
