Description

Technical Field

[0001] The utility model relates to the field of sewage treatment devices, in particular to a regulating type oilfield sewage treatment device. Background Art

[0002] In the process of oil field exploitation, for high permeability, loosely cemented sandstone reservoirs, due to their shallow burial depth, sand is easily produced from the strata. Due to the scouring effect, the sand particles in the sandstone reservoir strata intensify their shedding, resulting in a continuous increase in the amount of sand carried in the produced fluid.

[0003] Among them, the "regulating oilfield sewage treatment device" disclosed in the application number "CN202121194203.0" is also an increasingly mature technology, which "includes a sewage treatment device and a sewage recovery tank, a water inlet pipe is fixedly installed on the side wall of the sewage treatment device, a mixing box is fixedly installed at one end of the water inlet pipe, a stirring mechanism for adjusting sewage concentration and viscosity is fixedly installed on the inner side wall of the mixing box, a water pipe is fixedly installed on one side of the mixing box, and a first flow regulating valve is fixedly installed on the side wall of the water pipe". However, the treatment device still has the following defects during use:

[0004] When the treatment device stirs the sewage, the sewage is stirred unidirectionally by the stirring blades. Although the sewage and the reactants can be stirred evenly, the time required is relatively long, thereby reducing the working efficiency. In addition, the filter plate is installed inside the treatment device, and the effect of filtering the sewage by a single filtering method is not ideal. Utility Model Content

[0005] The purpose of the utility model is to provide a regulating oilfield sewage treatment device to solve the problems raised in the above background technology.

[0013] As a preferred solution of the utility model, the cast aluminum heating plate is electrically connected to an external power supply.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can accelerate the mixing speed of sewage and reactants through bidirectional stirring, thereby improving work efficiency. When in use, sewage is first injected into the treatment box, and then the reactants are injected into the sewage, the rotating rod and the screw are connected counterclockwise, and then the servo motor is started and the cast aluminum heating plate is electrically connected to the external power supply.

[0016] 2. The utility model can also filter solid particles in sewage through double filtration. When sewage reacts with reactants, the centrifugal force generated by stirring causes the oil in the sewage to approach the oil-absorbing sponge and be absorbed by the oil-absorbing sponge. Then the valve is opened to allow the sewage to flow out through the outlet pipe. In the process of sewage passing through the outlet pipe, the particles in the sewage are blocked and filtered by the activated carbon plate and the filter net. The double filtration of the activated carbon plate and the filter net can improve the quality of sewage filtration. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The transmission assembly 2 comprises a servo motor 21 mounted on the upper end of the processing box 1 , and a screw rod 22 is mounted on the output end of the servo motor 21 .

[0025] Specifically, the treatment box 1 is used for sewage and reactants to react therein, thereby purifying the sewage. The oil-absorbing sponge 7 can absorb the oil mixed in the sewage to reduce the pressure of the reactants on purifying the sewage. The cast aluminum heating plate 8 can heat the sewage, thereby accelerating the reaction speed between the reactants and the sewage and improving work efficiency. The servo motor 21 can drive the screw 22 to rotate and thus drive the stirring component 3 to rotate to stir the sewage.

[0026] In this embodiment: the stirring assembly 3 includes a rotating rod 31 installed on the side surface of the screw 22, a first screw hole 32 is opened at the upper end of the rotating rod 31, the rotating rod 31 is threadedly connected to the screw 22 through the first screw hole 32, a plurality of stirring rods 33 are staggeredly installed on the side surface of the rotating rod 31, and a plurality of stirring blades 34 are rotatably connected to the surfaces of the plurality of stirring rods 33, a mounting opening 35 is opened at the upper end of the processing box 1, and the servo motor 21 is movably installed inside the mounting opening 35.

[0027] Specifically, the first screw hole 32 and the screw rod 22 are threadedly connected, so that the rotating rod 31 can be connected to the servo motor 21. When the sewage is stirred, the servo motor 21 is started to rotate the rotating rod 31, and then the rotating rod 31 rotates the stirring rod 33 to stir the sewage. The power generated by the stirring of the sewage in turn rotates the stirring blades 34, so that the sewage can be stirred in both directions, thereby accelerating the fusion speed of the sewage and the reactants and improving work efficiency.

[0028] In this embodiment: the limiting assembly 4 includes a limiting ring 41 installed on the side surface of the servo motor 21, and the upper ends of the limiting ring 41 and the processing box 1 are both provided with a plurality of second screw holes 42, and the interiors of the plurality of second screw holes 42 are all threadedly connected with second bolts 43.

[0029] Specifically, the second bolt 43 is threadedly connected inside the second screw hole 42 so that the limiting ring 41 can fix the servo motor 21 , so that the servo motor 21 can be dropped into the processing box 1 .

[0030] In this embodiment, the water outlet assembly 5 includes a water outlet pipe 51 installed at the lower end of the processing box 1 , a valve 52 is fixedly installed on the side surface of the water outlet pipe 51 , and a threaded section 53 is provided on the lower side surface of the water outlet pipe 51 .

[0031] Specifically, the valve 52 can be used to control whether the water outlet pipe 51 is discharging water, and the threaded section 53 is used to enable the water outlet pipe 51 and the filter assembly 6 to be threadedly connected.

[0032] In this embodiment, the filter assembly 6 includes a screw ring 61 threadedly connected to the lower end of the water outlet pipe 51 , a filter screen 62 is fixedly installed at the lower end of the screw ring 61 , and an activated carbon plate 63 is fixedly installed inside the water outlet pipe 51 .

[0033] Specifically, the threaded connection between the screw ring 61 and the threaded section 53 enables the filter screen 62 and the activated carbon plate 63 to perform double filtration on particulate matter in the sewage, thereby improving the quality of sewage filtration.

[0034] In this embodiment, the material of the oil-absorbing sponge 7 is organic silicon polymer material.

[0035] Specifically, the oil-absorbing sponge 7 made of organic silicon polymer material can absorb the oil in the sewage without absorbing the sewage, thereby reducing the pressure of the reactants on the sewage purification.

[0036] In this embodiment: the cast aluminum heating plate 8 is electrically connected to an external power source.

[0037] Specifically, the electrical connection between the cast aluminum heating plate 8 and the external power supply enables the external power supply to transmit electrical energy to the cast aluminum heating plate 8, thereby heating the sewage, accelerating the reaction speed between the sewage and the reactants, and improving work efficiency.

[0038] Working principle: When in use, when filtering sewage, the utility model first injects sewage and reactants into the treatment box 1, and the rotating rod 31 is threadedly connected to the screw 22 counterclockwise, and then the cast aluminum heating plate 8 and the servo motor 21 are started at the same time. The servo motor 21 rotates clockwise and drives the stirring rod 33 to rotate. The stirring rod 33 drives the sewage and reactants to rotate, and drives the stirring blade 34 to rotate while the sewage is being stirred, thereby accelerating the speed of fusion of the reactants and sewage. At the same time, the cast aluminum heating plate 8 heats the sewage, which can also accelerate the speed of fusion of the reactants and sewage. In addition, the sewage throws the oil to the side wall of the treatment box 1 under the action of the centrifugal force generated by stirring, and contacts with the oil-absorbing sponge 7 so that the oil is absorbed by the oil-absorbing sponge 7. Finally, the valve 52 is opened to allow the sewage to flow out through the outlet pipe 51. In the process of the sewage passing through the outlet pipe 51, the particulate matter in the sewage is blocked and filtered by the activated carbon plate 63 and the filter net 62, thereby completing the treatment and purification of the sewage.
