4results about How to "Reduce dust removal efficiency" patented technology

The utility model provides a kind of mine ash removal device, it relates to mine dust removal technical field, including: casing, air inlet, air outlet, air cylinder, cyclone dust collector, support frame, hopper and electromagnetic pulse valve;The inside of casing is provided with filter dust board and filter dust bag;Electromagnetic pulse valve is set to the left side outside casing, and air pocket is fixedly connected on the lower side, and left side is fixedly connected with spout pipe.Filter dust board and filter dust bag, can carry out efficient filtration to working area dust, ensure optimum filtration effect, fixed plate right end is provided with rotary groove, rotary groove is provided with snap ring inside, snap ring can rotate, can realize filter dust bag rotation, avoid partial stress to cause filter dust bag cleaning uneven, spout pipe is provided with baffle, baffle can be moved according to the position of filter dust board and filter dust bag, design is more reasonable, can be targeted automatic flushing, reduce the risk of blockage, prolong equipment service life.

The utility model discloses a concrete raw material storing and discharging device, and mainly relates to the technical field of concrete. Comprising a discharging channel arranged at the bottom of a storage bin and a belt conveying mechanism used in cooperation with the discharging channel, the discharging channel is provided with a first valve and a second valve, the first valve and the second valve divide the discharging channel into a dust removal cavity and a discharging opening, and the outer side of the discharging channel is sleeved with a dust removal channel; the top of the dust removal channel communicates with an air inlet, a plurality of through holes communicating with the dust removal channel and the dust removal cavity are formed in the side face of the discharging channel, and a plurality of first shaking plates are slidably connected into the dust removal cavity in the radial direction. The concrete mixing device has the beneficial effects that the problem of dust doped in concrete raw materials is solved, the dust is prevented from diffusing everywhere, and the body health of workers is ensured.

The utility model discloses an environment-friendly pulse bag-type dust collector which comprises a shell and a motor, the motor is fixedly connected to the inner side wall of the shell, a cleaning assembly is arranged in the shell, and the cleaning assembly comprises a separation barrel, a dust storage box, a sliding plate, a collision plate, a reset spring and a treatment box. The separation barrel is rotationally connected to the lower end face of the shell, the dust storage box is fixedly connected to the lower end face of the shell, a sliding groove is formed in the side wall of the dust storage box, and the sliding plate is slidably connected into the sliding groove. The dust remover has the advantages that the cam is driven by the rotating shaft to rotate to drive the collision plate to slide, so that the sliding plate is opened and closed in a reciprocating manner, dust enters the dust storage box in a reciprocating manner, when the dust in the dust storage box needs to be cleaned, the motor is closed, the cleaning device stops but the dust remover can still work, dust removal operation does not need to be stopped, and the dust removal efficiency cannot be reduced.

The invention discloses an environmentally friendly dust removal process for cable tunnel construction, wherein the dust extracted from the tunnel is removed by a dust removal and demisting unit and then the gas is discharged; the upper and lower ends of each third baffle plate are respectively connected to the upper inner wall and the lower inner wall of the second muffler box, and the rear end of each third baffle plate is connected to the rear end inner wall of the second muffler box; a fourth baffle plate is arranged between each two adjacent third baffle plates, and the upper and lower ends of each fourth baffle plate are respectively connected to the upper inner wall and the lower inner wall of the second muffler box, and the front end of each fourth baffle plate is connected to the front end inner wall of the second muffler box; the two ends of the dust removal and demisting box are respectively provided with an air inlet end and an air outlet end, and the liquid generated in the dust removal and demisting unit is recycled through a circulation connection unit. The invention has the advantages of improving the dust removal effect, improving the construction environment, and avoiding the situation that the dust removal effect is reduced due to blockage and the shutdown is caused to affect the construction efficiency.
