Description

Sand collector

Technical Field

The utility model belongs to the technical field of steel surface treatment equipment technique and specifically relates to a sand collector.

Background

In the prior art, sand subjected to sand blasting is wet sand which is poor in flowability, some fine sand is generated in the sand blasting process, and the fine sand is required to be filtered and removed when the sand is not used for subsequent sand blasting. Therefore, the wet sand is dehydrated in a drying or air drying mode and then is reused in the current industry. A large amount of sand needs to be stockpiled and a large amount of space is occupied. In addition, the sand needs to be rapidly stirred by a stirring device in the process of preparing the mortar from the sand, and more energy is consumed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a sand collector, can collect the grit after will spouting and water and separate the screening under the effect of spin power, get rid of fine sand and unnecessary water.

In order to achieve the purpose, the utility model discloses a sand collector, which comprises a housin, the casing cross section on arbitrary horizontal plane is circular structure, the casing is inside hollow cylindric structure, and the terminal surface is the enclosed construction down at least, be provided with sand return pipe in the upper end of casing, be provided with sand outlet pipe at the lower extreme of casing, sand return pipe is 45-90 between the sand outlet direction in the casing and the diameter of the casing through this sand outlet, sand outlet pipe is 45-90 between the sand inlet direction in the casing and the diameter of the casing through this sand inlet, sand outlet direction of sand return pipe in the casing and sand inlet direction of sand outlet pipe in the casing are all along clockwise or all along anticlockwise; be provided with the delivery pipe in the bottom of casing, inside the delivery pipe penetrates the casing from the outside bottom through the casing of casing to upper portion in upwards extending to the casing, the tip opening of the delivery pipe in the casing up, set up the end cover at the inside delivery pipe end of casing, the end cover is opening semi-closed structure down, and inside the delivery pipe inserted the end cover, there was the clearance between the opening of end cover and the inner wall of end cover all and the inside delivery pipe of end cover.

Wherein the use of sand collector is connected to back the sand pipe to the sand groove, and the grit after the injection passes through back inside the casing that the sand pipe flows into sand collector with water, and goes out the sand pipe and be connected with the samming jar, and is connected with the mortar pump on the samming jar, and the mortar pump takes out the grit in the samming jar in-process can give out suction of sand pipe, ensures that the grit in the sand collector can export smoothly.

Above-mentioned 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 inlet direction of cooperation sand outlet pipe 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 sand equalizing tank simultaneously, make the mortar in the sand equalizing tank 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, high efficiency. 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.

The casing from top to bottom does in proper order: go up barrel, transition barrel, lower barrel, go up barrel and lower barrel and be hollow cylindric structure, and the lower extreme of lower barrel seals, goes up through transition barrel intercommunication between barrel and the lower barrel, and the diameter of transition barrel is dwindled by last barrel one side to lower barrel one side gradually, the sand return pipe set up on last barrel, the sand outlet pipe sets up on barrel down. The structural design of special sand collector, the diameter of the transition barrel of sand collector is less than barrel and lower barrel, and its inner structure is cavity circular cone platform type simultaneously, and the diameter dwindles gradually, so the mortar is at the increase of rotation in-process velocity of flow, and rotatory intensity is bigger, so is bigger to the centrifugal force that the grit produced, and the separation effect is better.

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 rotating speed of the sand in the sand collector can be improved as an optimal selection, and the loss of the self-rotating force is reduced.

The upper end of the shell is of an open structure, and a filter screen is arranged in the shell above the sand return pipe. The structure is used for adding new sand into the sand collector and filtering the new sand simultaneously.

The utility model provides a sand collector, it can collect the retrieval and utilization to spraying back wet sand through reasonable structural design to utilize to realize the rotation separation under the effect of rotation power, get rid of fine sand and unnecessary water, realize the instant continuous use of grit, can reduce the energy consumption, promote machining efficiency.
