Description

t

The invention relates to equipment for the separation of effluents and can be used in sewage treatment plants of livestock farms and complexes for trapping solid particles contained in manure drains.

A device for separating wastewaters is known, consisting of a receiving chamber, a distribution pipe, a liquid fraction collector and a fixed curved sieve consisting of a series of horizontal metal rods of special cross-section arranged perpendicular to the flow direction tn.

The disadvantage of the device is the absence of Me; There is an anism for cleaning a curved screen, as a result of which the space between the rods is clogged with debris, as well as the absence of a mechanism for adjusting the angle of the screen, which affects the performance and efficiency of the screen.

It is also known to include a device including a curved sieve placed in a body and means for changing its curvature G2.

A disadvantage of the known device is a significant energy cost due to the need to use an electric motor and a vacuum pump to create a vacuum and maintain continuous rotation of the sieve.

The closest in technical essence and the achieved result is a device containing a receiving chamber, a housing with slots and a curvilinear filtering element TOM, consisting of sections with means for changing the angle of inclination to the horizon, collections of solid and liquid fractions.

The disadvantage of this device is the inability to use it for the separation of livestock farms, due to

that the filter element is quickly clogged, and there is no reliable means for its regeneration. The availability of means for changing the curvature of the filter element is necessary when using the device in wastewater treatment plants for livestock farms and complexes, since the qualitative composition of animal waste drains, unlike industrial and household, varies considerably depending on the age and sex characteristics of animals and the technology of their maintenance and feeding.

The purpose of the invention is to increase productivity by preventing clogging of the filter element.

The goal is achieved by the fact that in a device containing a receiving chamber, a housing with slots and a curvilinear filtering element placed inside it, consisting of sections with means for changing the angle of inclination to the horizon, collections of solid and liquid fractions, means for changing the angle of inclination of sections to the horizon, located at the point of their articulation, is made in the form of a round rod with locking nuts at the ends, installed with the possibility of movement in the slots of the body, while the filter element is made of fabric, placed on drums with the possibility of rewinding.

It is advisable to make the filtering elements of nylon fabric, the receiving chamber, the body and the collections made of wood covered with plastic wrap, and the body should be supplied with a hose for washing the fabric located in the lower part of it.

FIG. 1 shows the device, a general VIEW} in FIG. 2 is a section A-L in FIG.

The device includes a receiving chamber 1, a collection of liquid fraction 2, an outlet for the liquid fraction 3, body C, nylon cloth 5 frame 6, drums for pulling and rewinding cloth 7 and 8, supporting rollers 9 hose for washing cloth 10, tool 11 for changing the angle of inclination of the filter element to the horizon, consisting of nuts 12 at the ends of round rods 13 and slots W, a tray for solid fraction 15, a handle for

rewinding the fabric 16 and the corners 17 to fasten the device to the floor.

The device works as follows.

During operation of the device, the effluent through the pipe is fed from above into the receiving chamber 1, the liquid fraction under the action of its own weight leaks through the holes of the nylon fabric 5 into the collection of liquid fraction 2 and is removed through the outlet 3. The solid particles, which are larger than the dimensions of the filter holes

5, roll down its inclined plane into the tray for removal of the solid fraction 15. The resulting precipitate is transported to the floor by mobile transport. Kapron fabric is fixed and only in the case of clogging holes (1 time per shift) is rotated by hand with (by the power of the drums 7 and 8 and the handle 16.

5 Therefore, this device does not need the means of energy supply.

A change in the curvature of the filter element increases the separation efficiency and the productivity of the device for varying degrees of sewage pollution.

At low contamination of the effluent, up to 15,000 mg / l, the bolts and round rods 13 of the means 11 for changing the angle of inclination of the filter element to the horizon are lowered all the way down the notch 14.

0 With an average pollution of drains up to 25000 mg / l, bolts and round rods 13 occupy a middle position in the slot x 1A. .

. At contamination above 50,000 mg / l j, the bolts and round rods 13 are fixed in the upper position in the slot X It. In this case, the effectiveness of removing contaminants reaches from 25 to 5, respectively.

 To eliminate corrosion of the metal and increase the durability of the device, the receiving chamber, housing and collections are made of wood coated with polyethylene film.

5 The effectiveness of the introduction of the device, compared with the current arc screens, is up to 1000 rubles per year per device.
