The utility model has simple structure, is filtered by the sediment of the filtering area, the first filter screen and the second filter screen, flows through the water outlet area, is precipitated again in the water outlet area due to the arrangement height of the water outlet, and is discharged finally, so that impurities are prevented from entering the sewer pipe, and the sewer pipe is not blocked.
Description
Technical Field
The utility model relates to the field of buildings, in particular to a filtering device for building material waste pulp.
Background
The building material waste slurry filtering device is a device for filtering building material waste slurry, and can be used for filtering cement mortar residues generated after experiments. At present, construction material laboratories are arranged in universities and colleges in China, waste slurry generated in the laboratories needs sedimentation treatment to be discharged into a sewer, or the sewer is easily blocked or water quality is polluted. Although some simple treatment devices exist at present, the sedimentation and filtration effects of the building material waste slurry device are not obvious, the cement residues after sedimentation and filtration are difficult to clean, the general waste slurry filtration device only has two-stage filtration, most of water is extremely difficult to flow out from a water outlet, and the difficulty of final cleaning is increased.
The simple treatment device used in most schools at present is a secondary filtration; the water tank is divided into a first filtering area and a second filtering area through the partition plate, a water inlet is formed in one side opening of the first filtering area, a water outlet is formed in the second filtering area, waste pulp enters the first filtering area from the water inlet, waste pulp is precipitated in the first filtering area, when the water level in the first filtering area exceeds the partition plate, water in the first filtering area flows into the second filtering area to continue precipitation, and when the water level reaches the water outlet, water is discharged. However, when the waste pulp is used, the effect is good when the flow rate of the waste pulp is very slow and the waste pulp amount is not large; however, sometimes when the experiment is performed, the waste slurry is poured in once, at this time, the waste slurry has a certain flow velocity and a relatively large amount, the sediment in the first filtering area is often washed out and brought into the second filtering area, and the sediment in the second filtering area is not yet precipitated and is discharged, so that the water outlet is often blocked, and the sediment is often cleaned. Furthermore, the division board is welded in the water tank, and the precipitate in first filtration district and the second filtration district is to separately clear up, and the division board is fixed in the centre, often can not clear up, has the dead angle.
Like the patent number 201610847414.7 which is disclosed at present, the name is a concrete mixing plant waste slurry recovery device, the name is 20202257182.0, and the name is a concrete waste water waste slurry rapid separation treatment device, which is aimed at the back discharge after separation, and the device is complex and is not applicable to places where the recovery and the direct discharge are not needed.
Disclosure of Invention
Based on the problems, the utility model provides a waste slurry sedimentation and filtration device, and building waste slurry flows through the device, and can be directly discharged only by waiting for the waste slurry to stand and then pumping out a baffle plate.
The technical scheme adopted by the utility model is as follows:
the waste slurry sedimentation and filtration device is a water tank without a cover, one side of the water tank is provided with a water outlet, and the other side of the water tank is connected with a water inlet pipe; a plurality of grooves which are parallel are formed on the inner walls of the two sides of the water tank; the baffle is inserted into the groove to divide the water tank into a filtering area and a water outlet area; a filter screen is arranged in the filter area; the filter screen is inserted into the groove.
The filter screen comprises a first filter screen and a second filter screen; the first filter screen and the second filter screen are respectively inserted into the grooves and are parallel; the first filter screen is positioned at the water inlet pipe; the pores of the first filter screen are larger than those of the second filter screen.
The first filter screen and the second filter screen are the same in height and the water tank;
the height of the baffle is lower than that of the water tank.
An outlet filter screen is arranged at the water outlet.
Further, the width of the filtering area is three times that of the water outlet area.
Further, the pore diameter of the first filter screen is 1mm; the pore diameter of the second filter screen is 0.03mm.
Further, the outlet filter screen pore diameter is 0.01mm.
Further, the water outlet is at least at the middle of the height of the water tank.
The utility model has simple structure, the construction waste slurry mainly comprises sand and cement, and the basic grain size of the sand is between 0.015 and 4.75 mm. Building waste pulp reaches the filtering area through the water inlet pipe, along with continuous addition of the building waste pulp, the building waste pulp also simultaneously passes through the first filter screen and the second filter screen when standing and precipitating, when the water level exceeds the baffle, the building waste pulp flowing into the water outlet area at the moment is precipitated and secondarily filtered, only a small amount of cement and sand stone are contained, the particle size is small, the optimal water outlet position is at least the middle position of the height of the water tank, the building waste pulp in the water outlet area is precipitated again in the water outlet area, discharged water can be directly discharged when the water level reaches the water outlet position, meanwhile, the filter screen is also installed at the water outlet, the secondary filtration is carried out, impurities are prevented from entering the sewer pipe, and the sewer pipe cannot be blocked.
The first filter screen, the second filter screen and the baffle adopt plug-in type, so that the water tank can be conveniently detached and cleaned.
