Description
Technical Field
The invention relates to the field of oil well cementing, in particular to a filter arranged at a water inlet at the bottom of a water tank of a cement truck.
Background
The cement truck dust remover removes dust by adopting an atomized liquid dust removal mechanism, has the advantages of irreplaceable dust removal of atomized liquid drops compared with other dust removal technologies, and is low in energy consumption, high in efficiency, safe and reliable in atomized dust removal. The effect of the atomized liquid droplets determines the quality of the dust removal effect. The dust remover adopts the atomizing nozzle to construct internal high-speed rotation in the rotational flow by liquid flow, so that the liquid flow has high angular momentum while flowing at high speed, and then the liquid drop is mixed with the pressure difference of air to realize the liquid drop breakage at the nozzle outlet, thereby achieving good atomizing effect.
However, the atomizing nozzles often become clogged during use. The main reason of analysis is due to the impurities in the cement truck water tank and the water tank of the drilling team. In construction, the water in the water tank is supplied to the water tank of the cement truck by using a submersible pump, and then the water in the water tank is pressurized by using a jet pump and is supplied to a nozzle of a dust remover, so that the water tank and the water tank of the cement truck are open, and various falling objects inevitably exist. In daily use, the manifold is usually required to be backwashed for better cleaning the manifold of the cement truck, so that residual cement slag in the manifold backflushs to the backwater tank to store the cement slag in the water tank, and the diameter of a nozzle of the dust remover is only 3mm, so that blockage in the using process cannot be avoided.

The invention aims to solve the technical problem of providing a filter arranged at the water inlet at the bottom of a water tank of a cement truck,
in order to solve the technical problems, the invention adopts the technical scheme that: a filter arranged at the water inlet at the bottom of a cement truck water tank comprises a flat plate with a round hole in the middle and a conical single flow cylinder inserted into a water inlet pipeline, wherein the conical single flow cylinder is wide at the upper part and narrow at the lower part, the outer diameter of the upper part of the conical single flow cylinder is slightly larger than the inner diameter of the water inlet pipeline, a check valve is arranged at the small-diameter end at the bottom of the conical single-flow cylinder, the large-diameter end at the top of the conical single-flow cylinder is fixed below the circular hole of the flat plate, the circular hole is matched with the conical single-flow cylinder, a three-stage filter screen is arranged on the upper surface of the flat plate, wherein the inner filter screen is tightly attached to the circular hole of the flat plate to cover the inlet of the conical single-flow barrel, the middle filter screen is tightly sleeved outside the inner filter screen in a cap shape, the outer filter screen is tightly sleeved outside the middle filter screen in a cap shape, the bottom surfaces of the middle filter screen and the outer filter screen are tightly attached to the upper surface of the flat plate, and the sieve pores of the inner filter screen, the middle filter screen and the outer filter screen are sequentially enlarged.
The outer filter screen is used for filtering impurities more than 10mm, the middle filter screen is used for filtering impurities more than 5mm, and the inner filter screen is used for filtering impurities more than 2 mm.
The length of the conical single-flow cylinder is at least three times of the cylinder diameter of the large diameter at the top, so that the conical single-flow cylinder cannot be completely ejected out during backflushing), and at the same time, the conical single-flow cylinder is reinserted into the water inlet pipeline under the action of gravity when the backflushing is finished.
The outer diameter of the upper part of the conical single flow cylinder is slightly larger than the inner diameter of the water inlet pipeline, so that a gap of 3-5 mm exists between the bottom surface of the flat plate and the bottom surface of the cement truck water tank.
The outer wall of the conical single-flow cylinder is coated with an elastic rubber material, so that the sealing effect with a water inlet pipeline is improved.
The invention has the beneficial effects that: on the one hand, the spraying pump can be prevented from supplying impurities above 2mm to the dust remover, the blockage is not easy to occur, and meanwhile, the filter can be effectively prevented from being blocked reversely when the reverse flushing is carried out, and the problem of nozzle blockage of the dust remover can be effectively solved.
