Referring to fig. 1, the present utility model provides an apparatus 100 for preventing a liquid containing solid powder from clogging a pipe, comprising: a primary settling vessel 110, a secondary settling vessel 120, a liquid inlet pipe 130, and a liquid outlet pipe 140.

Specifically, the liquid inlet pipe 130 is used for connecting with a machine for generating waste liquid, that is, the used cutting liquid, grinding liquid and other waste liquid containing solid powder can directly enter the liquid inlet pipe 130, the liquid outlet of the liquid inlet pipe 130 is corresponding to the liquid inlet of the first-stage precipitation container 110, so that the liquid to be treated of the liquid inlet pipe 130 can enter the first-stage precipitation container 110, in this embodiment, the first-stage precipitation container 110 is in a pool shape with an open top, the liquid outlet of the liquid inlet pipe 130 is arranged at the edge of the first-stage precipitation container 110, and the waste liquid of the liquid inlet pipe 130 flows into the first-stage precipitation container 110 as shown by an arrow in fig. 1.

The primary sedimentation container 110 mainly performs primary sedimentation on solid-containing waste liquid, the primary sedimentation container 110 can be made of stainless steel or other corrosion-resistant materials, and in order to meet the requirement of primary sedimentation, the primary sedimentation container 110 has the following dimensions: the width and length of the bottom is about 40cm and the height is about 20cm, although in other embodiments the dimensions may be increased if better mounting conditions are provided.

The liquid inlet of the first-stage precipitation container 110 is provided with a first slope extending to the bottom of the container along the liquid flow direction, the waste liquid of the liquid inlet pipe 130 falls into the first-stage precipitation container 110 from the liquid outlet, the movement direction of the waste liquid is inclined downwards under the action of gravity, the first slope can guide the flow direction of water flow to a certain extent, the water flow speed can be further reduced, the waste liquid can effectively stay in the first-stage precipitation container 110, most of solid powder is precipitated at the bottom of the first-stage precipitation container 110, the waste liquid is clearer closer to the top and clearer further from the liquid inlet pipe 130.

It should be noted that, the inclination degree of the first slope may affect the flow guiding effect to a certain extent, in this example, the inclination angle of the first slope with respect to the vertical direction is 30 ° to 60 °, for example, may be 45 °, and the angle may enable the waste liquid to sufficiently flow to the bottom of the first-stage precipitation container 110, which is beneficial to the effective deposition of the solid powder.

Referring again to fig. 1, the secondary sedimentation vessel 120 sediments the waste liquid after primary sedimentation again, and likewise, the material of the secondary sedimentation vessel 120 may be stainless steel or other corrosion-resistant materials, and in order to achieve the requirement of sufficient sedimentation, the size of the secondary sedimentation vessel 120 is as follows: the width and length of the bottom is about 40cm and the height is about 20cm, although in other embodiments the dimensions may be increased if better mounting conditions are provided.

The top of the primary settling vessel 110 is in communication with the top of the secondary settling vessel 120, through which the relatively clear liquid overflowed from the top of the primary settling vessel 110 may be caused to flow into the secondary settling vessel 120 for re-settling.

Specifically, in this embodiment, the primary settling vessel 110 and the secondary settling vessel 120 are adjacent through a sidewall, and the primary settling vessel 110 starts to have an overflow port 111 at the top of the adjacent sidewall, the overflow port 111 being in communication with the secondary settling vessel 120. That is, during processing and preparation, the primary sedimentation container 110 and the secondary sedimentation container 120 can be integrally processed and formed, the pool depth of the primary sedimentation container 110 is slightly higher than that of the secondary sedimentation container 120, and the height difference is just the opening of the overflow port in the vertical direction.

It should be noted that, in other embodiments, the primary sedimentation container 110 and the secondary sedimentation container 120 may be separately disposed, and the tops of the primary sedimentation container and the secondary sedimentation container 120 may be communicated through a shorter pipeline, or the top of the secondary sedimentation container 120 may be lower than the waste liquid outlet at the top of the primary sedimentation container 110, i.e. the middle pipeline for communicating is disposed obliquely downward.

The top of the secondary settling vessel 120, which is relatively far from the primary settling vessel 110, is in communication with a drain 140. After the waste liquid subjected to primary sedimentation enters the secondary sedimentation container 120, solid powder is sedimented again under the action of gravity on the bottom of the secondary sedimentation container 120 in the movement process, and the liquid is clearer when reaching the top of the secondary sedimentation container and is clearer when being far away from the primary sedimentation container 110.

Further, in the present embodiment, a second slope opposite to the first slope is provided on a side of the secondary sedimentation container 120 connected to the drain pipe 140.

The setting of the second slope can enable the liquid to stay for a longer time in the second-stage sedimentation container 120, so that sedimentation is more sufficient, and further, a more clarification effect is achieved. The waste liquid treated by the secondary precipitation can not easily block the pipeline in the subsequent transportation process.

Further, in order to further monitor the liquid level of the primary sedimentation container 110 and the secondary sedimentation container 120, a liquid level monitor 160 is provided on each of the primary sedimentation container 110 and the secondary sedimentation container 120. In this embodiment, the level monitor 160 may be disposed at the top of the sidewall. The liquid level detector can monitor the liquid level, and an ultrasonic measuring device, a laser measuring device or other measuring devices can be selected. It should be noted that, in other embodiments, only the primary sedimentation container 110 or only the secondary sedimentation container 120 may be provided with the liquid level monitor 160.

The redundancy of primary settling vessel 110 and secondary settling vessel 120 can also be checked in real time by real-time level monitor 160.

In the first-stage precipitation vessel 110 and the second-stage precipitation vessel 120, the solid powder is deposited continuously at the bottom, and when the solid powder is deposited to a certain extent, the flow of the water flow will disturb the deposited solid powder, and the residence time of the water flow will be reduced, so that the effect of removing the solid powder will be poor, therefore, in this embodiment, the grating 150 is disposed at the middle lower part and the bottom of the first slope of the first-stage precipitation vessel 110 and the middle lower part and the bottom of the second slope of the second-stage precipitation vessel 120. Since the grating 150 generates bright light, the deposited solid powder can be deposited by covering the grating 150 to block the bright light emitted from the grating 150, so that the thickness of the deposited solid powder can be determined by the bright light condition of the grating 150. When the solid powder is deposited to a certain degree, the solid powder is cleaned in time, so that the better solid powder removing effect of the device is kept for a long time.

In this embodiment, since the primary sedimentation container 110 and the secondary sedimentation container 120 are both pool-shaped, it can be directly observed whether the grating is blocked through the top. In other embodiments, if the primary sedimentation vessel 110 and the secondary sedimentation vessel 120 are closed vessels, a viewing window for easy observation needs to be provided at the top. Or the top wall is directly made of transparent materials.

It should be noted that, in other embodiments, the grating 150 may be disposed only in the primary sedimentation container 110 or the grating 150 may be disposed only in the secondary sedimentation container 120, and when the reaction needs to be cleaned, both sedimentation containers may be cleaned at the same time.

In other embodiments, when the primary sedimentation container 110 and the secondary sedimentation container 120 are both sealed containers, the primary sedimentation container 110 and the secondary sedimentation container 120 are both provided with a venting device to control the pressure inside the container, and the venting device is further connected with the waste gas treatment device, so that the treatment process is cleaner, and no pollution is caused by the leakage of the generated volatile gas into the air.

In this embodiment, the bottom of the primary settling vessel 110 and the bottom of the secondary settling vessel 120 are provided with weighing devices 170. The weighing device is disposed at the common bottom of the first-stage precipitation container 110 and the second-stage precipitation container 120, so that the total weight can be detected by the weighing device, and theoretically, the weight can be continuously increased due to continuous deposition of the solid powder, and the amount of the sediment can be monitored by weight detection, so that the weighing device can be matched with the grating 150 for monitoring, and the sediment can be cleaned in time, so that a better treatment effect can be maintained.

It should be noted that, in other embodiments, a weighing device may be disposed at the bottom of the first sedimentation container 110 and the second sedimentation container 120, and a water-proof isolation may be made to monitor the sedimentation weights in the two sedimentation containers, and separate the time periods for cleaning.

Still other embodiments of the present utility model provide a waste liquid treatment system including the apparatus 100 for preventing a pipe from being clogged with a liquid containing solid powder as described above, the apparatus 100 for preventing a pipe from being clogged with a liquid containing solid powder being directly connected to a machine tool that generates waste liquid through a liquid inlet pipe 130, and a liquid outlet pipe 140 being connected to other purifying apparatuses.

In summary, the solid-containing waste liquid directly discharged from the machine stage reduces the water flow speed under the action of the first slope of the first-stage precipitation container 110, the waste liquid can stay in the first-stage precipitation container 110 for a short time, most of the solid powder is precipitated at the bottom of the first-stage precipitation container 110, and the waste liquid enters the second-stage precipitation container 120 for reprecipitation after preliminary clarification. The solid content of the waste liquid after the twice precipitation is obviously reduced, the further transportation and treatment of the waste liquid are facilitated, and meanwhile, the precipitated solid waste residue is easy to clean in time.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
