Description

Oil field sewage treatment dosing device Technical Field The invention relates to the technical field of sewage treatment, in particular to an oilfield sewage treatment dosing device. Background The oilfield waste liquid becomes an industry problem because of complex and changeable components and severe treatment standards. The treatment sites are often located in mountain hilly areas with complicated remote places, face the practical constraints of narrow road roundabout and bumpy road conditions, and are difficult to provide the wide working space required by large-scale hoisting equipment, so that the traditional large-scale waste liquid treatment equipment encounters significant obstacles in transportation and field installation. In order to adapt to the special working environment, a skid-mounted design scheme is generally adopted in the chemical agent adding link in oilfield waste liquid treatment, the core preparation mode is mainly divided into a single skid single tank type mode and a double tank type combined mode, the device is a complete set of equipment integrating functions of chemical agent adding, stirring and mixing, liquid conveying, automatic control and the like, the aim of optimizing the water quality regulation and purification effect in the sewage treatment process is achieved, and the main function is to accurately add various chemical agents such as flocculating agents, disinfectants, pH adjusting agents and the like into sewage so as to achieve water quality improvement, harmful substance removal and water resource utilization rate improvement. The Chinese patent application CN120364824B discloses a dosing sewage treatment device for sewage treatment, which is characterized in that a cavity and a dosing mechanism are equipped with liquid medicine, so that clear water for preparing the liquid medicine is injected into a preparation cavity before sewage treatment, a ball is rotated, a medicament flowing into a ball groove is led out of the drug injection cavity under the rotation of the ball and falls into the clear water under the action of gravity, the high-concentration medicament and the clear water are premixed in the preparation cavity to prepare the low-concentration liquid medicine, the condition that the medicament is contacted with the sewage in advance to generate floccules is avoided due to the fact that the clear water is stored in the preparation cavity, the density difference between the medicament and the sewage can be reduced due to the fact that the concentration of the liquid medicine is lower than that of the medicament, and further the possibility that the floccules are generated before stirring is further reduced due to the fact that the dispersion and the uneven mixing caused by the concentration difference is avoided. However, when the structure is used, the medicine adding process depends on the water flow to impact the spherical impeller to drive the ball to rotate so as to realize medicine dripping, medicine injection points are relatively fixed and concentrated, and the fixed point adding mode ensures that the initial diffusion range of the diluted medicine is still limited when the diluted medicine enters the main body of the huge sewage treatment tank, the concentration gradient still exists, the contact and initial mixing effect of the medicine and sewage cannot be optimized from the source, and therefore homogenization still needs to be realized by depending on subsequent strong mechanical stirring, and the risk of secondary shearing on formed floccules exists. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an oilfield sewage treatment dosing device, which solves the problems proposed by the background technology. The invention aims at realizing the technical scheme that the oilfield sewage treatment dosing device comprises a placing frame, a mixing barrel arranged on the placing frame, and further comprises: The barrel cover is arranged at the upper end of the placing rack, and a medicine storage groove is arranged in the barrel cover; The hollow shaft is rotationally connected to the inner middle part of the rack, an L-shaped pipe is arranged on the outer side of the hollow shaft, a linear groove is formed in the outer side of the vertical part of the L-shaped pipe, a sleeve is rotationally connected to the outer side of the L-shaped pipe corresponding to the position of the linear groove, and a spiral groove is formed in the sleeve; The lower end of the hollow shaft is communicated with the output end of the medicine storage groove through a quantitative siphon component, and the sleeve rotates to change the intersection point of the spiral groove and the linear groove. Further, the quantitative siphon assembly includes: the quantitative tank is fixed at the upper end of the outer side of the mixing barrel, a pipe cover is fixed in the quantitative tank, the lower end of the pipe cover is of an opening structu
