Abstract

The utility model discloses a horizontal directional drilling rig mud device. The top side of a mud tank is provided with a vibrating sieve which is composed of a sieve body, a sieve, and a public known vibrator. The sieve is fixed at the lower part of the sieve body. The vibrator is fixed at the side of the sieve body. An elastic air cushion is arranged between the sieve body of the vibrating sieve and the mud tank. A mud pump for conveying mud adopts a piston pump which can bear high foreign matters. The utility model reduces the times for stopping the pump to exchange a plug, improves drilling speed, saves mud raw materials, and solves environmental pollution problem.

Description

The horizontal directional drilling machine mud device

The utility model discloses a kind of horizontal drill mud device.

Use plunger displacement pump to carry high-pressure work mud in the tubing operation at present, but it is low that plunger displacement pump bears the impurity ability, in drilling process, need often to change plunger, for example, in pan soil matter is crept into, just needed to change plunger in about one hour, seriously restricting the progress of creeping into, in addition in drilling process, some residue mud are overflowed by pilot hole, the environment around having polluted.

The purpose of this utility model is to design a kind of horizontal directional drilling machine mud device that uses the piston pump slurry conveyed and set up recovery mud mechanism for overcoming above-mentioned weak point, has improved rate of penetration and has improved surrounding environment.

The utility model content, on slurry tank, establish vibrosieve, vibrosieve is made up of sieve nest, screen cloth and known vibrator, screen cloth is fixed on the bottom of sieve nest, vibrator is fixed on the side of sieve nest, be provided with the rubber-like air cushion between vibrosieve sieve nest and the slurry tank, the slush pump of slurry conveyed adopts and bears the high known piston pump of impurity ability.

The utility model advantage because piston pump has the higher impurity ability of bearing, is compared with the plunger displacement pump of former usefulness, and the number of times that plug is changed in termination of pumping significantly reduces, thereby has improved the progress of creeping into.Mud veclamation mechanism is handling through vibrosieve with the residue mud of crossing, and gets rid of foreign material and mud is sent into slurry tank for usefulness again, saved raw material, also solved problem of environmental pollution.

Description of drawings:

Fig. 1 is the utility model schematic diagram.

Fig. 2 is a vibrosieve cross-sectional structure schematic diagram.

Further specify the utility model embodiment below in conjunction with accompanying drawing, the utility model is to now using the improvement of mud device, on slurry tank 3, there is not vibrosieve 11, vibrosieve is by sieve nest 13, screen cloth 15 and vibrator 12 are formed, screen cloth is fixed on the bottom of sieve nest, vibrator is two, can on market, purchase, two vibrators are separately fixed on the two sides of sieve nest, be provided with four air cushions 14 between vibrosieve sieve nest and the slurry tank, after vibrator starts, vibrosieve just begins vibration, by electric submersible pump 10 with the residue slurry transportation of use in the mud pit in vibrosieve, after vibrosieve sieves foreign material by vibrosieve from and be used as garbage disposal from right-hand member discharge, mud by vibrosieve enters slurry tank for reusing, not only save raw material but also solved problem of environmental pollution, slurry conveyed adopts piston pump, because that piston pump bears the impurity ability is higher, reduce termination of pumping relatively and changed the number of times of plug, improved the speed in the tubing process; Swell soil is sent into by charging hopper 1, and water is added by water pipe 2, and both mix in slurry tank and are stirred by centrifugal pump 6.Centrifugal pump is driven by motor 5, and this motor is by generator 4 power supplies, and the mud that stirs is extracted out by piston pump 8 and is sent to rig through its outlet 9 and pipe, and diesel engine 7 is the power source of piston pump.

Claims

1, a kind of horizontal directional drilling machine mud device, comprise loading hopper, water pipe, agitator and conveying mechanism, it is characterized in that: be provided with vibrosieve above the slurry tank, vibrosieve is made up of sieve nest, screen cloth and known vibrator, screen cloth is fixed on the bottom of sieve nest, vibrator is fixed on the side of sieve nest, and the rubber-like air cushion is set between vibrosieve sieve nest and the slurry tank, and the slush pump of slurry conveyed adopts and bears the high known piston pump of impurity ability.
