Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to the technical field of concrete slurry separation devices. Background Art

[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand, stone as aggregates and water in a certain proportion, which are mixed and obtained by mixing. It is also called ordinary concrete.

[0003] In the actual production process of a concrete mixing plant, each time a concrete mixer truck transporting concrete to a construction site comes back, the remaining concrete in the tank needs to be cleaned out by washing with water to prevent it from condensing into lumps in the tank. Most of the concrete slurry that has been cleaned out currently uses the method of graded sedimentation to separate the water and sand and gravel in the concrete slurry. However, when using the multi-stage sedimentation method to separate water and sand and gravel, not only does the multi-stage sedimentation tank occupy a large area, but the slurry separation efficiency is also low, which has a certain impact on normal production. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a concrete slurry separation device, which realizes the real-time and rapid separation of concrete slurry, occupies a small area, has a high separation efficiency, and is more adaptable to actual production needs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The concrete mud separation device comprises a shell, a pillar, and a spiral conveying rod, wherein the shell is fixedly mounted on the pillar, an inflatable belt is fixedly mounted on the top plate inside the shell, an air pipe connected to the inflatable belt is fixedly mounted on the top plate of the shell, a first electric gate valve is fixedly mounted on the air pipe, a double-layer filter plate is fixedly mounted on the lower end of the shell, the double-layer filter plate is filled with filter particles, a through slot is provided on the side plate of the shell above the double-layer filter plate, a row of brackets are arranged on the shell at the through slot, one end of the row of spiral conveying rods is rotatably mounted on the bracket, and the other end of the spiral conveying rod is rotatably mounted on the side plate on the other side of the shell, a transfer case is fixedly mounted on the outside of the shell, the output shafts of the transfer case are respectively connected to the rows of spiral conveying rods in transmission, a motor is fixedly mounted on the transfer case, the output shaft of the motor is connected to the input shaft of the transfer case in transmission, a discharge slide is also fixedly mounted on the outside of the shell, and the discharge slide is correspondingly connected to the through slot,

[0008] Preferably, the inflatable belt is provided with a telescopic expansion joint.

[0009] Preferably, the filter particles are coarse sand or stone particles with a diameter of 1-2 cm.

[0010] Preferably, the discharge chute is arranged in a U shape.

[0011] The beneficial effects that can be achieved by the utility model using the above technical solution are:

[0012] 1. A double-layer filter plate is fixedly installed at the lower end of the shell, and the double-layer filter plate is filled with filter particles. When the concrete slurry enters the shell from the feed pipe, the water will be filtered from the double-layer filter plate into reusable water, and the silt will be discharged from the discharge chute under the action of the spiral conveying rod, thus realizing the separation of slurry and water of the concrete slurry;

When the shell is filled with mud, the inflatable belt will be compressed, the second electric gate valve and the third electric gate valve will be closed, and the first electric gate valve will be opened to inflate the inflatable belt and squeeze the mud, which can accelerate the separation speed of mud and water;

[0014] 3. By setting the discharge slideway to a U-shaped material sealing mechanism, the mortar in the U-shaped material sealing mechanism will form a relatively sealed space inside the shell, which is conducive to completing the squeezing of the mud by the air belt inflation.
