Mute air exhaust port of a roller type sand making machine

Abstract

The invention discloses a mute air exhaust port of a roller type sand making machine, and relates to the technical field of sand making machines. The mute air exhaust port of the roller type sand making machine comprises a base, the top of the base is fixedly provided with a crushing box through a support, a dust removal box is further fixedly arranged at the top of the base, an upper air suctionpipe and a lower air suction pipe are fixedly connected to the right wall of the dust removal box, and the upper air suction pipe and the lower air suction pipe correspondingly penetrate through the left wall of the crushing box and extend to the upper side and the lower side of a screen; an air outlet is formed in the top wall of the dust removal box, and a grid plate is fixedly clamped at the air outlet, the inner top of the dust removal box is fixedly connected with a fan through a support, the dust removal box is provided with a first drawer, the first drawer is located below the fan, andsliding grooves matched with the first drawer are formed in the front left side wall and the rear left side wall of the dust removal box correspondingly; and a rectangular port is formed in the bottomof the first drawer, and a filter screen is fixedly connected in the rectangular port. According to the mute air exhaust port, dust generated in the sand making process is collected and filtered, sothat the air pollution is reduced, and the human health of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of sand making machines, in particular to a silent air exhaust port of a roller sand making machine. Background technique [0002] The sand making machine is an adjustable fine crushing equipment without sieve bars, which can be widely used in the fine crushing of raw materials and clinker in cement plants. It is especially suitable for the processing and crushing of hard limestone, dolomite, granite, basalt and other artificial sand or highway pavement stone. [0003] When the sand making machine is working, a large amount of dust will be generated, and the dust is easily inhaled by the human body, which will have an adverse effect on the health of the staff. In order to create a suitable working environment, it is necessary to set up a dust removal device to collect and filter the dust; the existing dust removal device is in When filtering dust, etc., the service life of the filter screen is low, and the ...
