[0002] During the process of oil extraction, it is inevitable to mix in sewage. However, when the existing oil sewage treatment device opens the oil outlet pipe at the moment of oil output, it will cause oil to gush out, resulting in oil spillage, causing oil pollution.

[0022] As Figure 1An apparatus for precisely controlling the process of treating oil sewage, comprising a housing body, a separation cavity 8, a sealed lower end head 9, a discharge seat body 10 and a buffer seat body 11.

A support block 4 integrally connected with the outer wall of the lower housing is provided on the outer wall of the lower housing. A support leg 5 is vertically connected to the bottom of the support block. The lower housing is suspended by the support legs at the bottom.

The lower end of the hollow connecting rod is communicated with the discharge seat body through a first electromagnetic valve. The buffer seat body is installed at one end of the discharge seat body and a petroleum spraying buffer mechanism is arranged therein. The discharge seat body is communicated with an oil outlet pipe 12 through the buffer seat body. A pressure valve 14 is installed at the other end of the discharge seat body. A drain pipe is arranged at the bottom of the discharge seat body. A second electromagnetic valve 13 is installed on the drain pipe. The separation cavity is rotatably connected in the lower housing under the action of a rotation driving mechanism. An electric cylinder 7 is installed at the bottom of the lower housing. The output shaft end of the electric cylinder extends into the lower housing and is connected with the sealed lower end head. The sealed lower end head is driven by the electric cylinder to extend into the lower end of the separation cavity and seal it. The sealed lower end head is rotatably connected with the output shaft end of the electric cylinder. An oil-water inlet 3 is arranged at the top of the upper housing. A filtering and guiding structure is installed in the upper housing. The discharge port at the lower end of the filtering and guiding structure is directly above the upper end of the separation cavity. During operation, first, the oil with sewage is sent into the housing body through the oil-water inlet. The oil with sewage first passes through the filtering and guiding structure to remove large impurities and then enters the separation cavity. The rotation driving mechanism drives the separation cavity to rotate, and the centrifugal force is used to accelerate the stratification of the oil and the sewage. The electric cylinder is started to separate the sealed lower end head from the lower end of the separation cavity. First, the stratified sewage is sent into the discharge seat body and discharged through the drain pipe. When the water is discharged completely, the second electromagnetic valve is closed to make the oil fall into the discharge seat body. The first electromagnetic valve is closed and the pressure valve is opened. The discharge seat body is pressurized through a pressure pipeline. The oil enters the buffer seat body under the action of the pressure and is conveyed out through the oil outlet pipe. In the utility model, a petroleum spraying buffer mechanism is arranged in the buffer seat body. When the pressure is too high, the petroleum spraying buffer mechanism automatically seals the oil outlet pipe to prevent oil pollution caused by oil jetting.

[0023] As Figure 3The filtering and guiding structure shown includes a horn-shaped guiding cover 23, a mounting cylinder 24, and a filter plate 22. The filter plate is disc-shaped and is evenly provided with a number of filter holes thereon. The outer diameter of the filter plate matches the outer diameter of the mounting cylinder. The filter plate is detachably mounted on the upper end of the mounting cylinder. The horn-shaped guiding cover is wider at the top and narrower at the bottom. The mounting cylinder is fixed to the inner wall of the upper housing by bolts. The upper end of the horn-shaped guiding cover is fixed to the inner wall of the upper end of the mounting cylinder. The oil-water inlet is located directly above the filter plate. The lower end of the horn-shaped guiding cover extends into the lower housing and is located directly above the upper end of the separation cavity. The utility model automatically removes large impurities in petroleum and sewage during the feeding process through the filter plate.

[0024] As Figure 1 and Figure 2 shown, a mounting seat 19 for mounting a bearing 20 is fixed to the inner wall of the lower housing. The bearing is sleeved on the outer wall of the separation cavity. The separation cavity is rotatably connected in the mounting seat through the bearing. The upper end of the mounting seat is also detachably connected with an annular limiting cover 21. The bearing is restricted in the mounting seat by the annular limiting cover. The rotation driving mechanism includes a rotation motor 17, a driving gear 16, and a transmission gear 15. The transmission gear is sleeved and fixed on the outer wall of the separation cavity. The separation cavity rotates together with the transmission gear. The rotation motor is fixed to the inner wall of the lower housing. The driving gear is sleeved on the output shaft of the rotation motor and meshes with the transmission gear. The utility model quickly separates petroleum and water by centrifugal force, and discharges them one by one after stratification, thereby removing sewage in petroleum and playing a role in increasing the practical performance.

[0025] As Figure 1 shown, a lifting ring 18 for hoisting is detachably mounted on each of the left and right outer walls at the upper end of the separation cavity. The utility model adopts the above structure to play a role in facilitating the hoisting of the separation cavity.

[0026] As Figure 4 shown, a first guiding channel 10-1 is provided in the discharge seat body. The pressure valve and the first electromagnetic valve are both communicated with the first guiding channel. The bottom surface in the first guiding channel is inclined to the left. An outlet communicating with the drain pipe is provided at the bottom of the left end of the discharge seat body. An oil outlet is provided in the discharge seat body at the upper right end of the first guiding channel. The first guiding channel is communicated with the oil outlet.

[0027] As Figure 4 and Figure 5A second diversion channel 11-1 is provided in the shown buffer seat body. One end of the second diversion channel faces the oil outlet directly and is connected to it. An oil outlet channel 11-4 is provided in the buffer seat body below the second diversion channel. One end of the oil outlet channel is connected to the second diversion channel, and the other end of the oil outlet channel is connected to an oil outlet pipe. The petroleum spraying buffer mechanism includes a valve core 11-2 and a spring 11-3. The upper end face in the second diversion channel is inclined and is provided with a trapezoidal guiding strip 11-5. The upper end face of the valve core is parallel to the upper end face in the second diversion channel. A chute matching the trapezoidal guiding strip is also provided on the upper end face of the valve core. The valve core slides along the trapezoidal guiding strip through the chute. One end of the valve core away from the oil outlet is connected to the other end of the second diversion channel through a spring. The lower end face of the valve core is flat. The lower end face in the second diversion channel is also flat and parallel to the lower end face of the valve core. The valve core contacts the lower end face in the second diversion channel through its lower end face to seal the oil outlet channel. When the pressure in the discharge seat body increases, the increased pressure will push the valve core to compress the spring, causing the valve core to move along the trapezoidal guiding strip. When the pressure exceeds the expected range, the lower end face of the valve core will contact the lower end face in the second diversion channel, thereby sealing the oil outlet channel and closing the oil outlet pipe. In the utility model, a petroleum spraying buffer mechanism is provided in the buffer seat body. When the pressure is too high, the petroleum spraying buffer mechanism automatically seals the oil outlet pipe to prevent petroleum pollution caused by petroleum jetting.

All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should be regarded as within the protection scope of the present utility model.
