Among the above-mentioned technical scheme, can follow the sand collector with new sand material and add, get into the jar of samming through the sand collector to carry to sand liquid proportional control ware under the effect of mortar pump, discharge most low pressure water in the sand liquid, and carry high proportion mortar to the spray gun, let in high pressure water to the spray gun through high pressure water pump simultaneously, high pressure water and high proportion mortar are erupted from the spray gun after mixing in the spray gun. The structural form of the spray gun can adopt Chinese patent application: 2019224259529, but may be other types of known structures. One of the spray guns sprays towards the inner wall of the steel pipe, the other spray gun sprays towards the outer wall of the steel pipe, and the spray guns axially move along the steel pipe under the action of the extension arms and the telescopic mechanisms due to the fact that the steel pipe rotates under the action of the roller set, so that all parts of the inner surface and the outer surface of the steel pipe can be sprayed. The steel pipe frame is arranged between the two rollers, at least one of the rollers is driven by a power mechanism to form a driving wheel, and the rotating directions of all the rollers are consistent and the speeds of all the rollers are consistent. The telescopic mechanism can be a guide rod arranged on the frame, and the guide rod is driven by a gear rack mechanism, an air cylinder, an oil cylinder and the like to move and stretch. The sand-liquid proportion regulating valve is used for discharging most of low-pressure water in the mortar entering the sand-liquid proportion regulator so as to improve the proportion of sand materials in the mortar.

The structure of sand collector is: including casing, delivery pipe, the casing is from top to bottom in proper order: the sand return pipe is connected to the upper barrel of the shell, and an included angle between the sand outlet direction of the sand return pipe in the upper barrel and the diameter of the upper barrel passing through the sand outlet is 45-90 degrees; the connecting pipeline is arranged on the lower cylinder and extends into the lower cylinder, and an included angle between the sand feeding direction of the connecting pipeline in the lower cylinder and the diameter of the lower cylinder passing through the sand feeding position is 45-90 degrees; the sand outlet direction of the sand return pipe in the upper cylinder body and the sand inlet direction of the connecting pipeline in the lower cylinder body are both clockwise or both anticlockwise; the bottom of barrel penetrates and extends to the upper portion of transition barrel under the delivery pipe, be provided with the end cover on the inside delivery pipe of transition barrel, the end cover can be connected on the inner wall of transition barrel or fix on the delivery pipe through the connecting piece, the end cover is the semi-closed structure of opening down, the end cover back-off is on the delivery pipe, all there is the clearance between the inside delivery pipe of opening and the inner wall of end cover and end cover.

The sand return pipe is vertical to the diameter of the upper cylinder passing through the sand outlet in the sand outlet direction in the upper cylinder; the connecting pipeline is vertical between the sand feeding direction in the lower cylinder and the diameter of the lower cylinder passing through the sand feeding position.

The sand outlet pipe is vertical to the diameter of the sand homogenizing tank passing through the sand inlet position in the sand homogenizing tank in the sand inlet direction.

Wherein the sand return pipe and the connecting pipeline are in a horizontal state in the shell.

Above-mentioned sand collector's technical scheme design, the sand return pipe carries the mortar in the sand return groove to sand collector, because the design of its sand outlet direction, the rational design of the sand direction of advancing of cooperation connecting tube simultaneously, can realize that the mortar in the sand collector produces the rotation of a direction, when the mortar pump outwards takes out the mortar in the samming jar simultaneously, make the mortar in the samming jar produce rotatoryly, the suction that produces simultaneously can make the connecting tube with the mortar suction in the sand collector, under the effect of initiative suction, the rotation rate of the mortar in the sand collector is faster, and is efficient. Because some parts of the sprayed sand are fine sand, the coarse sand can be positioned on the outer wall of the sand collector in the rotating process of the sand collector, and part of water and the fine sand are positioned in the middle and are discharged from the discharge pipe, so that the coarse sand and the fine sand can be separated, the filtering is not needed, an additional stirring mechanism is not needed, and the energy consumption is reduced. In addition, the diameter of the transition cylinder of the sand collector is smaller than that of the upper cylinder and that of the lower cylinder due to the structural design of the special sand collector, and meanwhile, the inner structure of the sand collector is a hollow cone frustum shape, and the diameter of the transition cylinder is gradually reduced, so that the flow speed of mortar is increased in the rotating process, the rotating strength is higher, the centrifugal force generated by coarse sand is larger, and the separation effect is better.

When the steel that is processed is the product beyond the steel pipe, can arrange the position and the quantity of spray gun at telescopic machanism's tip according to the demand of reality, can select suitable roller train simultaneously, realize the removal of flat steel or the rotation of cylindricality steel.

The sand liquid proportion regulator is structurally characterized in that: the accelerating device comprises a rotating shell and an accelerating shell, wherein the rotating shell is of a hollow cylinder structure, the accelerating shell is of a hollow cone structure, one end with a large diameter of the accelerating shell is connected with the lower surface of the rotating shell, the inner hollow structures are communicated with each other, the diameter of the largest position of the inner hollow structure of the accelerating shell is smaller than or equal to that of the inner hollow structure of the rotating shell, an output pipe is arranged at the position with the smallest diameter of the accelerating shell, an air inlet hole is formed in the output pipe, a drain pipe is arranged at the top of the rotating shell, the drain pipe penetrates through the rotating shell to extend into the rotating shell or the accelerating shell, the end part of the drain pipe is positioned at the central axis of the rotating shell; the pipe of the output of the mortar pump is connected to the rotating housing at an angle of 45-90 ° between the output direction in the rotating housing and the diameter of the rotating housing at the output position.

The output of the slurry pump is plumbed between the output direction within the rotating housing and the diameter of the rotating housing at the output location.

The acceleration casing be ceramic material or accelerate the lower half of casing for ceramic material or accelerate the inner wall of casing the lower half be ceramic material.

In the above scheme, the mortar conveyed to the mortar liquid proportion regulator by the mortar pump through the pipeline rotates under the action of self-rotation force after entering the rotary shell, and gradually flows downwards in the acceleration shell under the action of gravity and is finally output from the output pipe, because the acceleration shell is of a conical structure, the speed of the internal rotation of the mortar can be gradually accelerated along with the reduction of the diameter of the mortar, the mortar can be positioned on the outer walls of the acceleration shell and the rotary shell to walk under the action of centrifugal force when rotating sand, water and a small amount of fine sand can be in the middle, and simultaneously, under the action of pressure, part of water can be discharged from the water discharge pipe, and the valve controls the water discharge amount so as to form high-proportion mortar. In addition, the output pipe is connected to the spray gun through a pipeline, the spray gun can generate negative pressure in the output pipe, sand in the shell can be sucked out in an acceleration mode, in order to enable the sand to be conveyed more smoothly, the air inlet hole is formed in the conveying pipe, internal air pressure is supplemented, and smooth water discharge in the drainage pipe is also guaranteed.
