Description

New pneumatic device

technical field

The utility model relates to a novel pneumatic device, which mainly converts a compressed air source into a vibration device.

Background technique

The outlet of the linear fluidized bed dryer is equipped with an electric vibrating screen. Due to the high power consumption of the motor, the production line has sufficient compressed air source, so that the original materials cannot be effectively used and energy is wasted. .

Contents of the invention

In order to overcome the defects of the prior art, the utility model provides a novel pneumatic device which saves energy and transforms pneumatic into vibration. The technical solution of the utility model is: a new type of pneumatic device, which is characterized in that it includes a bracket, an air motor, a screen box, a rubber shock absorber and a vibrating screen. On the horizontal plate, the periphery of the screen box is provided with a rubber shock absorber, and the screen box is installed on the support through the rubber shock absorber, and the upper and lower ends of the screen box are provided with a feed inlet and an outlet The feed port, the feed port is matched with the annular outer ring of the vibrating screen.

The vibrating screen includes an annular outer ring, the bottom of the annular outer ring is sealed with a screen, the inner wall of the bottom end of the annular outer ring is provided with an annular protrusion, and a bottom ring matched with the annular protrusion is also included. , the periphery of the screen is installed between the annular protrusion and the bottom ring, and is fastened by screws. A well-shaped bracket is installed at the bottom of the screen, and each end of the bracket is placed on the bottom. on the inner wall of the circle.

The outside of the annular outer ring communicates with one end of a conveying pipeline, and the other end of the conveying pipeline communicates with a coarse material outlet.

There are three rubber shock absorbers, which are evenly distributed on the periphery of the screen box.

The utility model has the advantages of converting pneumatic into vibration, making full use of resources and saving energy.

Detailed ways

A new type of pneumatic device, which is characterized in that it includes a bracket 4, an air motor 2, a screen box 1, a rubber shock absorber 5 and a vibrating screen 3, and the air motor 2 is installed on a raised horizontal wall on one side of the periphery of the screen box 1. On the plate 13, the periphery of the screen box 1 is provided with a rubber shock absorber 5, and the screen box 1 is installed on the support 4 through the rubber shock absorber 5, and the upper and lower ends of the screen box 1 are provided with There is a feed port 11 and a discharge port 12, and the feed port 11 is matched with the annular outer ring 31 of the vibrating screen 3.

The vibrating screen includes the annular outer ring 31, the bottom of the annular outer ring 31 is sealed with a screen 32, the inner wall of the bottom end of the annular outer ring 31 is provided with an annular protrusion 311, and also includes an annular The bottom ring 36 matched with the protrusion 311, the periphery of the screen 32 is installed between the annular protrusion 311 and the bottom ring 36, and is fastened by screws 37, so that the screen 32 is fixed more firmly. When vibrating, it is not easy to loosen. A well-shaped support 35 is installed at the bottom of the screen 32, so that the screen itself is loaded and supports the screen 32. Each end of the support 35 is placed on the bottom of the screen. On the inner wall of circle 36.

The outer side of the annular outer ring 31 communicates with one end of a conveying pipe 33, and the other end of the conveying pipe 33 communicates with a coarse material outlet 34. The fine material filtered by the screen 32 falls directly, and the coarse material that cannot be filtered is During the vibration process, it enters the coarse material outlet 34 through the conveying pipe 33 and is finally discharged through the coarse material outlet 34.

There are three rubber shock absorbers 5, which are evenly distributed on the periphery of the screen box.

The working principle of the utility model: After the air motor is connected to the steam, it shakes, and then drives the screen box and the vibrating screen on the screen box to vibrate. Since the periphery of the screen box is equipped with a rubber shock absorber, the screen box will not If too much vibration occurs, the fine material will fall directly from the discharge port after being vibrated, and the coarse material will be discharged from the coarse material outlet through the conveying pipeline.
