Long-lasting separating device for mortar cleaning in concrete mixer truck

Abstract

The invention discloses a long-lasting separating device for mortar cleaning in a concrete mixer truck. The structure of the long-lasting separating device for mortar cleaning in the concrete mixer truck comprises a material receiving box, a feeding opening, a plate frame, a separating cavity and a filter disk, wherein the material receiving box and the plate frame are integrated; the feeding opening is fixedly welded to one end of the material receiving box, and the feeding opening communicates with the interior of the material receiving box; the filter disk is installed in the separating cavity; and the material receiving box is internally provided with a feeding cavity, a fixing disk, a filter screen, a discharging cavity, a driver and a swing type mechanism, wherein the feeding cavity,the discharging cavity and the filter disk are integrated and matched in a communication mode. According to the long-lasting separating device for mortar cleaning in the concrete mixer truck, the swing type mechanism is used for forming a bottom protecting system of the filter screen, swing shafts of the swing type mechanism form a bowl-shaped structure and are matched with the filter screen, andthus the condition that the deformation of the filter screen is too large is restricted; and the conditions that the filter screen is separated from the fixing of the fixing disk due to the fact thatthe deformation of the filter screen is too large under the long-term pressure of mortar and gravel, and as a result, the filter effect is affected by too large gaps between iron wires are prevented,and the applicable deadline of the filter screen is prolonged effectively.

Description

technical field [0001] The invention relates to the field of separation of concrete mixer trucks, in particular to a long-term separation device for cleaning mortar in concrete mixer trucks. Background technique [0002] Concrete mixer truck (commercial concrete truck) is also often called snail truck because of its shape. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete, and it will always keep stirring during transportation. The cylinder rotates to ensure that the carried concrete will not solidify. However, this type of mixing tank often needs to be cleaned after the work is finished, and the mortar and pebbles produced after washing are precipitated and then filtered and separated. When filtering with a filter, the filter is mainly composed of fine iron wires to form a hollow structure. , while the mortar and pebbles are under heavy pressure for a long time, and the filter screen is easily detached and deformed, and needs to be r...

However, this type of mixing tank often needs to be cleaned after the work is finished, and the mortar and pebbles produced after washing are precipitated and then filtered and separated. When filtering with a filter, the filter is mainly composed of fine iron wires to form a hollow structure. , while the mortar and pebbles are under heavy pressure for a long time, and the filter screen is easily detached and deformed, and needs to be replaced frequently. In this way, the filter screen is not conducive to long-term use
