Description

A kind of surface sand screening equipment for permeable brick

technical field

The utility model relates to the field of surface sand screening equipment, in particular to a surface sand screening device for permeable bricks.

Background technique

The permeable brick originated in the Netherlands. During the process of building the city by the Dutch people, it was found that the ground after draining the sea water would cause continuous ground subsidence due to the long-term lack of water contact. Once the dykes on the coastline are washed away, the sea water will quickly rush to cities much lower than sea level and completely submerge the entire coastal city. In order to prevent the ground from sinking, the Dutch made a small pavement brick with a length of 200 mm, a width of 100 mm and a height of 50 or 60 mm, which was laid on the street pavement, and a gap of 2 mm was reserved between the bricks. In this way, when it rains, the rainwater will seep into the ground through the gaps between the bricks. This is the later famous Dutch brick.

In the prior art, raw materials with a certain particle size are usually mixed and stirred until they are pressed and formed. The utility model found that the size of the raw material particles directly affects the water permeability and aesthetics, and the size of the raw material particles also affects the ratio.

Preferably, a second conveyor belt is connected to the outlet end of the hopper.

Preferably, the lower surface of the outlet of the hopper is provided with a secondary filter screen for screening.

Preferably, directly below the hopper outlet is connected with a third conveyor belt located directly below the hopper outlet through an inclined trough-shaped groove.

Preferably, the rotation directions of the motor I and the motor II are opposite.

Preferably, a protective cover connected to the hopper is provided outside the cylindrical mixing barrel.

The beneficial effects obtained by the utility model are as follows: the cylindrical mixing bucket can be set to screen and classify while stirring; the set rotating blade can make the raw materials run from one direction to the first conveying belt; the set hopper can make the fine raw materials It is screened from the cylindrical mixing tank, and the screen is screened multiple times to obtain products with different particle sizes and uniformity. During the screening process, the raw materials will not be mixed in the filter screen to cause clogging and affect product quality.
