Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1, in oil drilling of the invention disclosed by the invention drilling fluid reclamation level-one solid-liquid separating equipment
Including cabinet 1, cabinet side is equipped with push plate 3, push rod 4 is connected with after push plate, and push rod can connect the driving equipments such as motor or cylinder,
In the left side of push plate, it is equipped with sprue 2 above cabinet, on the left of sprue, sieve 10 is equipped with below cabinet, is equipped on the left of sieve
Partition group is rotated, which includes four orthogonal rotation partitions 5, and connect by shaft 6, under each partition
It holds close to the bottom of box, can just block the intracorporal space of case, partition left side is equipped with block 8 and fixed block 7 in the bottom of box,
Block and fixed block are connected by reset spring 9, on the downside of block contact rotation partition, and apply certain pressure to partition.Sieve
Side off the net is equipped with separation chamber 11, is equipped with baffle 12 below separation chamber.
When carrying out drilling fluid reclamation, push plate is retreated into the cabinet rightmost side first, is then added by sprue with coarse
The drilling fluid slurries of particle silt push push rod followed by driving equipments such as motor or cylinders, and driving push plate is moved toward left side,
As shown in the arrow of the rightmost side Fig. 1, slurries are squeezed, and squeeze rotation partition simultaneously, are entreated shown in arrow as shown in figure 1, this
Partition is rotated when a, closed state is kept due to the pressure by block from reset spring, therefore slurries are by two sides
Extruding force, under the action of extruding force, the drilling fluid in slurries is extruded, and is separated under the effect of gravity by sieve
Room, when push plate continues past left movement, slurries are pressed further by, and the pressure that partition is subject to incrementally increases, when the pressure is big
When the pressure of reset spring, partition starts to push block open, and is rotated clockwise along the arrow direction of the leftmost side Fig. 1,
It separates with block, is further processed as shown in Fig. 2, the silt for being removed drilling fluid at this time is pushed into partition rear space,
Partition continues to be rotated by 90 °, and second piece of partition is contacted with block, and cabinet space is closed under the action of reset spring, and push plate pushes away
Dynamic slurries continue to repeat the above process, and until the separation of solid and liquid of all slurries is completed, opening baffle is to the drilling well after separation at this time
Liquid carries out next step separation of solid and liquid.
Three pieces of partitions can be set into embodiment as one preferred, rotation partition group, and the angle of partition room is
120 °, it is bigger that one-pass quantity of sand and mud is rotated in this way.Larger suitable for certain silt contents, drilling well liquid hold-up is not high, and needs
The slurries processing quickly handled.
As another preferred embodiment, Gu can be arranged according to the sediment content of slurries the blocks of different groups of numbers/
Determine block/return spring mechanism, to apply power of different sizes to partition, the different maximum extrusion pressures for being subject to slurries are fitted
The separation of solid and liquid requirement for the slurries for answering quantity of sand and mud different implements very simple and very flexible.
As another preferred embodiment, sieve connecting vibration motor can be increased into the sieving of drilling fluid
Amount, but vibration frequency is excessive that silt is easy to cause to fall the part mesh for blocking sieve, will affect separating effect instead.By reality
Border the study found that this process and reset spring restoring force, i.e. the maximum extrusion pressure that is subject to of slurries is related, if extruding force compared with
Greatly, then silt is compacted to a certain degree, is then turned on vibrating motor on this basis, is just not easy to block mesh.Therefore conduct
It is preferred that 5 ~ 10 groups of block/fixed block/return spring mechanisms of setting, the maximum extrusion pressure for being subject to slurries are higher than 2000Pa, simultaneously
Make the vibration frequency of sieve not higher than 500Hz.The separative efficiency of drilling fluid can be significantly improved, and makes clogging situation significantly
Mitigate.
The above is only presently preferred embodiments of the present invention, is not intended to limit the invention in any way, it is all according to the present invention
Technical spirit any simple modification to the above embodiments, change and equivalent structural changes, still fall within skill of the present invention
In the protection scope of art scheme.
