A pressure filter system for concrete truck cleaning fluid

technical field

The utility model relates to the field of concrete processing, in particular to a pressure filter system for cleaning fluid of concrete vehicles.

Background technique

Concrete mixer trucks are special trucks used to transport concrete for construction. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum will always be kept rotating to ensure that the carried concrete will not solidify.

Concrete mixer truck is composed of automobile chassis, mixing drum, transmission system, water supply device, full power power take-off, front and rear brackets of mixing drum, reducer, hydraulic transmission system, feeding and discharging system, operating mechanism and other parts. After the concrete has been transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space, so that the volume of the mixing drum becomes smaller and smaller. So there are some cleaning devices for cleaning concrete trucks now.

For example, the patent with the application number CN201720199753.9 discloses a cleaning device for cleaning concrete mixer trucks. There are multiple water outlets on the support frame, the bottom of the cavity is connected to the waste liquid pool, and multiple water spray pipes are arranged in the flushing platform. The support frame includes a frame body and a reinforcement plate at the bottom of the frame body. The outer side is inserted with a limit plate that abuts against the frame; flushing pipes are symmetrically arranged on both sides of the flushing platform, and the flushing pipes include a fixed pipe and a movable pipe that moves back and forth in the vertical direction; there are multiple flushing holes on the fixed pipe , the movable pipe includes a hard pipe and a hose flange connected to both ends of the hard pipe. There are multiple cleaning holes on the hard pipe. The two ends of the hard pipe are symmetrically equipped with a driving mechanism that drives the movable pipe to move, which can automatically clean the concrete mixer truck. The outer wall of the machine is cleaned, and the waste obtained by cleaning can be cleaned at the same time.

However, the waste water after cleaning is often directly discharged everywhere, causing greater pollution and waste of water resources.

The conveyor belt 18 is arranged obliquely upward towards the waste residue pool 5 . The frame 19 is provided with baffles 20 along both sides of the conveyor belt 18 for preventing materials from falling off the conveyor belt 18 from both sides of the conveyor belt 18 . The first driving motor 17 is fixedly installed on the frame 19 , and the output shaft of the first driving motor 17 is connected to one of the driving rollers 16 . The first driving motor 17 drives the transmission roller 16 to rotate, thereby driving the transmission belt 18 to rotate, and then transports the waste residue into the waste residue pool 5 .

As shown in Figures 1 and 5, in order to allow more concrete to enter the plate-and-frame filter press 3 for pressure filtration, the collection tank 2 is provided with a stirring mechanism 21 for stirring the waste water.

Therefore, the particles in the waste water in the collection pool 2 are distributed more evenly, so that as much concrete as possible can enter the plate and frame filter press 3 to separate waste residue and water, and then fully recycle the concrete.

The working principle of the filter pressure system is as follows:

1. The waste water enters the collection pool 2 from the concrete truck, and the stirring mechanism 21 in the collection pool 2 stirs the waste water to make it as uniform and turbid as possible;

2. The waste water is pumped into the plate and frame filter press 3 through the pump 10, and the plate and frame filter press 3 squeezes out the water in the waste water and discharges it into the reuse pool 4. This part of the water can continue to be used for concrete make;

3. The concrete block that has been pressed out of water is discharged from the slag outlet of the filter press and falls onto the conveyer belt 18. With the movement of the conveyer belt 18, the waste slag is driven to move towards the waste slag pool 5 until it falls to the In the waste slag pool 5, the collection of concrete is completed, and this part of waste slag can be dried and crushed to continue to be used as aggregate
