Dust falling mechanism for clean production of commercial concrete

Abstract

The utility model relates to the technical field of dust falling mechanisms, and discloses a dust falling mechanism for clean production of commercial concrete, which comprises a dust falling suppression fence detachably fixed on a concrete feeding hopper, and an atomizing nozzle is arranged in the dust falling suppression fence and used for vibrating water into atomized water mist particles to form a water mist barrier. The dust suppression fence is combined with the dust suppression fence, so that normal feeding can be guaranteed, and dust raising of materials is effectively suppressed at the same time. Flying dust is effectively restrained under the action of a water mist barrier formed by the fence body of the dust fall restraining fence and the atomization nozzles, the weight of the flying dust is increased through atomized water vapor, at the moment, the negative pressure exhaust fan exhausts air outwards so that negative pressure can be formed in the dust fall restraining fence, and the dust fall is restrained. And as the weight of the raised dust is increased by the water vapor, the raised dust is greatly influenced by the negative pressure, the raised dust dives downwards along with inertia under the action of the negative pressure wind, and the phenomenon of dust flying is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction mechanisms, in particular to a dust reduction mechanism for clean production of commercial concrete. Background Art

[0002] Concrete mixing station is mainly composed of five systems including mixing host, material weighing system, material conveying system, material storage system and control system and other ancillary facilities. Compared with the aggregate measurement of the station, the aggregate measurement of the floor reduces four intermediate links, and the material measurement is vertical, which saves the measurement time and greatly improves the production efficiency.

[0003] A mixing station unloading hopper device and a concrete mixing station are provided with the publication number CN103286858B. The mixing station unloading hopper device comprises: a unloading platform; a bracket, a first end of which is hinged on the first column of the unloading platform to form a first hinge point, and a second end is detachably connected to the second column of the unloading platform; a unloading hopper device, one side of the bucket body of which is detachably hinged on the bracket, and the other side is hinged on the bracket to form a second hinge point; and a push-pull device, one end of which is hinged on the bracket, and the other end is hinged on the bucket body and can drive the bucket body to rotate around the second hinge point. When the unloading hopper device of the concrete mixing station needs to repair the bucket body, the bucket body is lowered from a higher height to a lower position from the ground through two rotations of the bracket and the bucket body, and is rotated to an angle that is convenient for maintenance personnel to repair the bucket body, which not only facilitates the transportation of the bucket body from a high place to the ground, but also facilitates the maintenance of the bucket body at a low place, reducing the danger of maintenance personnel's operation.

[0004] The above-mentioned mixing station unloading hopper device and concrete mixing station are convenient for maintenance personnel to repair the hopper body. It is not only convenient for the transportation of the hopper body from a high place to the ground, but also for maintenance of the hopper body at a low place, thereby reducing the danger of maintenance personnel's operations. However, the current traditional concrete mixing station has limited dust reduction effect during use, causing air pollution. Workers are prone to breathing discomfort when loading, unloading and repairing. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to overcome the above-mentioned problems, a dust reduction mechanism for clean production of commercial concrete is provided, which solves the above-mentioned problems.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] The dust reduction mechanism for clean production of commercial concrete includes a dust suppression enclosure detachably fixed on the concrete feeding hopper, wherein an atomizing nozzle is arranged in the dust suppression enclosure for vibrating water into atomized water mist particles to form a water mist barrier, which effectively suppresses the rising of dust. When combined with the enclosure of the dust suppression enclosure, normal feeding can be ensured while effectively suppressing the dust of the material.

[0008] Preferably, in order to further suppress dust, a negative pressure exhaust fan is fixedly installed in the dust suppression enclosure. The negative pressure exhaust fan exhausts air outwards to quickly reduce the air pressure in the dust suppression enclosure, making it difficult for dust to rise under the action of negative pressure.

[0009] Preferably, the negative pressure exhaust fan is located below the atomizing nozzle.

[0010] Preferably, a series of water pipes are fixedly provided on the inner wall of the dust reduction suppression enclosure, and the atomizing nozzles are fixed on the series of water pipes at intervals. The series of water pipes are connected to an external water tank with a water pump, and the water pump supplies water into the series of water pipes and quickly atomizes water through the atomizing nozzles.

[0011] Preferably, a dust filter core is fixedly provided at the inner air inlet of the negative pressure exhaust fan, and the dust filter core is used to block dust.

[0012] Preferably, a clamping block is welded and fixed on the lower end face of the dust suppression enclosure, the clamping block has a slot for clamping on the feeding hopper of the concrete mixing station, and a transverse clamping bolt is fixed on the clamping block for clamping the dust suppression enclosure on the feeding hopper of the concrete mixing station.

[0013] The advantages and positive effects of the utility model are: the water mist barrier formed by the dust reduction suppression enclosure and the atomizing nozzle effectively suppresses the dust, and the weight of the dust is increased by atomizing water vapor. At this time, the negative pressure exhaust fan is used to exhaust the dust to the outside so that a negative pressure is formed in the dust reduction suppression enclosure. Since the dust is heavier due to the water vapor, it is more affected by the negative pressure. Under the action of the negative pressure wind, the dust dives downward by inertia, thereby avoiding the phenomenon of dust flying. BRIEF DESCRIPTION OF THE DRAWINGS
