Description

An oilfield production wastewater filter equipped with a self-cleaning structure

Technical field

The utility model relates to the technical field of oil field oil production sewage filters, specifically an oil field oil production sewage filter equipped with a self-cleaning structure.

Background technique

Most of the sewage generated during the water injection oil well cleaning process is directly discharged, causing great pollution to the environment and wasting water resources. Furthermore, because the sewage contains solid particles such as sediment, it is easy to re-enter the oil pipeline. Causes pipeline blockage, which will affect the production of the oil transportation system after entering the main line. Therefore, the sewage needs to be filtered and then used for well cleaning, so the oil field oil production sewage filter will be used for treatment;

Publication No. CN201001993Y discloses a filtering device for oilfield water injection and well cleaning water. When in use, the water inlet pipe is connected to the water injection well vent valve, and the water outlet pipe is connected to the oil well pipeline. Sewage enters the filter through the water inlet pipe and is sprayed from its outlet port onto the inclined plate. Under the action of gravity, solid particles such as sand and dirt blocks slide down the inclined plate and fall into the lower storage bin. The sewage carrying part is smaller. The particles move upward in the cylinder, and are blocked by the filter, fall to the inclined plate, and then slide down to the lower storage bin. The sewage with solid particles removed passes through the filter and enters the oil pipeline through the outlet pipe to complete the well cleaning. Under the blocking effect, there is a relatively stable environment under the inclined plate, and solid particles will not be flushed upward after entering;

However, the above scheme still has the following problems during use: when in use, the filter is set at the upper end of the water inlet and at the lower end of the water outlet. The sewage needs to reach a certain height to achieve filtration. It is difficult to filter and the sewage is easy to filter. It flows out directly from the water inlet and is filtered through a single filter. The filtration efficiency is low, and the filter is prone to clogging after being used for a long time, thus affecting the sewage filtration work.

Therefore, we propose an oilfield production wastewater filter with a self-cleaning structure to solve the above-mentioned problems.

The details are as follows:

1. The large impurity particles in the sewage can be intercepted through the set filter, thereby preliminary treatment of the sewage. A small amount of dirt will come into contact with the filter material at the bottom, neutralize the dirt, and then treat the sewage. Purification is carried out, and finally it is filtered from the filter plate and discharged from the outlet pipe. After the motor drives the shaft to rotate, the shaft will drive the cleaning rod to rotate. After the cleaning rod rotates, it will self-clean the filter and remove the intercepted impurities. It is discharged from the waste port. When the shaft rotates, it will drive the hemisphere to rotate synchronously. After the hemisphere rotates, it will intermittently squeeze and conflict with the knocking rod, thereby pushing the knocking rod to collide with the bottom of the filter, thereby compressing the spring. It causes the filter to vibrate, further improving the efficiency of impurity cleaning, thereby completing the self-cleaning process;

2. The rotation of the set shaft will drive the stirring rod to rotate, thereby stirring the filter material laterally. When the shaft rotates, it will also drive the triangular block to rotate synchronously. After the triangular block rotates, it will intermittently squeeze with the flipping rod. The friction causes the flipping rod to rotate, and then reverses the torsion spring, thereby flipping the filter material vertically, so that the filter material can more fully neutralize and purify the sewage, and at the same time, it can also prevent the filter material from becoming hardened. .
