Automatic feeding device for drilling fluid circulating tank

Abstract

The invention discloses an automatic feeding device for a drilling fluid circulating tank, and belongs to the technical field of drilling engineering circulating system machinery. The device is characterized by comprising a gantry crane, a charging bin, a discharging bin door which is used for discharging and is arranged at the bottom of the charging bin, and a slurry preparation funnel, wherein the charging bin is connected to the gantry crane; the slurry distribution hopper for communicating the drilling fluid circulating tank is arranged on the hoisting path of the gantry crane; the slurrydistribution hopper is positioned at the bottom of the gantry crane; and the discharging bin door is over against the receiving port of the slurry distribution hopper when the gantry crane hoists theloading bin to the position above the slurry distribution hopper. According to the device, a treating agent can be automatically added into the slurry preparation hopper, so that the labor capacity isreduced, and the potential safety hazard of feeding is eliminated. The feeding speed is controllable in a certain range, and the fine maintenance of the performance of the drilling fluid can be realized. The time can be reserved, the charging door bin can be opened for automatically charging materials while time is reached, so that the manpower is saved.

Description

technical field [0001] The invention belongs to the technical field of drilling engineering circulation system machinery, and in particular relates to an automatic feeding device for a drilling fluid circulation tank. Background technique [0002] Drilling fluid treatment agent is an important chemical additive in drilling production. The drilling fluid prepared with it can stabilize the well wall, reduce friction and drag, and carry cuttings. It is necessary to add a large amount of drilling fluid treatment agent during the drilling process. At present, it is manually added to the slurry mixing funnel, which has problems such as heavy labor, uneven feeding speed, and great impact on the performance of existing drilling fluids. In addition, there is a safety hazard of splashing treatment agent and hurting people.
