The movable dust removal equipment without the filter element comprises a base plate, a gas storage main pipe, a fan,a swirler set, an air inlet main pipe, a water supply device and a spraying device; a walking structure is arranged on the base plate; one end of the air inlet main pipe is connected with an air inlet of the fan; one end of the gas storage main pipe is connected with an air outlet of the fan, and the other end of the air storage main pipe is closed; the swirler set comprises a plurality of swirler, the inlet of each swirler is in communication with the gas storage main pipe through an extension pipe, and the lower outlet is downwards arranged; and the water supply device is connected with thespraying device through a pipeline with a water pump and is used for supplying water to the spraying device.

The invention discloses a fully automatic high-speed intelligent printing slotting die-cutting machine, which includes a paper feeding device, a printing device, a drying device, a slotting device and a collecting platform arranged in sequence from right to left, and the paper feeding device includes an input roller table device, lifting cylinder, blower and wind cover, the lifting cylinder is fixed at the left end of the frame of the input roller table device, a baffle is fixed on the piston rod of the lifting cylinder, the wind cover is arranged directly above the input roller table device, and the blower The air outlet of the air outlet is connected to the top port of the wind hood through the pipe; the drying device includes the second frame, the power unit, the air outlet pipe, the air heater and the induced draft fan, and the air outlet pipe is rotatably installed on the top of the second frame , one end of the air outlet pipe extends downwards in the second frame and a turntable is fixed on the extension end. The beneficial effects of the invention are: compact structure, improved printing quality, improved corrugated cardboard production efficiency, and the ability to change the distance between two grooves and the size of the groove width.

The invention discloses a ventilating device with a cleaning function and relates to the technical field of ventilating devices. The present invention includes shell one and shell two, and shell one and shell two are spliced ​​together to form a ventilation channel, wherein, the middle part of the formed ventilation channel is a columnar cavity, and the air outlet and air inlet provided in the ventilation channel are all along the columnar shape. The distribution of the tangential direction of the cavity; the side of the second shell is opened with the dust outlet 1 and the dust outlet 2, which are connected with the ventilation channel. There are several dust-collecting parts installed on the runner; a dust discharge groove is extended on the inner side of the second dust outlet, and the dust discharge groove is connected with the columnar cavity, and the second rotating part is installed in the dust discharge groove. The invention pushes the installed runner to rotate through air, and after part of the air enters the runner and the columnar cavity, the air is left still, and the sand and dust in the air fall on the flat plate of the runner under the action of gravity, and the sand and dust follow the rotation of the flat plate until it rotates to the exhaust. At the dust tank, dust removal is completed.

Disclosed is a deep-well high-stress coal rock stepped drum, comprising a rear cylinder hub (1), a front cylinder hub (2), a spiral blade (3), an end plate (4), nozzles (5) and pick-shaped cutters (6). The end plate (4) is arranged at the joint of the rear cylinder hub (1) and the front cylinder hub (2), the spiral blade (3) connected to the end plate (4) is arranged on the rear cylinder hub (1), a plurality of pick-shaped cutters (6) and nozzles (5) are distributed on the outer edge of the spiral blade (3) and the end plate (4) at intervals, and the pick-shaped cutters (6) in spiral arrangement are fixed on the front cylinder hub (2); and the end plate (4) is provided with an annular water delivery channel (4-5), and is provided with a nozzle water delivery channel (4-3), a wheel hub water delivery channel (4-4) and an end plate blade water delivery channel (4-6) which are in communication with the annular water delivery channel (4-5). With the drum, the mechanical mining problem of deep-well high-stress coal rock is solved, and deep-well high-stress coal rock cutting efficiency is increased in the case that explosion-proof motor power is not greatly increased. The structure uses an explosion-proof motor drive, such that underground explosion-proof requirements can be satisfied, and the shearer drum has a simple and compact structure.
