Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1, a system for recycling cleaning waste liquid in a tank of a cement tank truck comprises a waste liquid pool 1, a liquid collecting tank 2, a sand-stone separator 3, a parking platform 16, a multistage sedimentation tank 13 and a drainage ditch 5; the liquid collecting tank 2 is arranged on one side of the parking platform 16; the multistage sedimentation tank 13 is arranged on the other side of the parking platform 16, and the upper surface of the parking platform 16 inclines towards the multistage sedimentation tank 13;
the liquid collecting tank 2 is provided with a liquid adding pipe 4 used for injecting cleaning liquid into a tank body of the cement tank truck, a liquid flow channel 21 is arranged in the liquid collecting tank 2, the liquid flow channel 21 is connected to an inlet of the sand-stone separator 3, a stirring device 6 and a submersible pump 7 are arranged in the waste liquid pool 1, an outlet of the submersible pump 7 is connected to the liquid adding pipe 4 through a first pipeline 8, and an outlet of the submersible pump 7 is connected to concrete water utilization equipment in a plant area through a second pipeline 9; the drainage ditch 5 is arranged between the water outlet of the sand-stone separator 3 and the waste liquid pool 1; the waste liquid pool 1 is also connected with a water replenishing pipe 10 for replenishing clear water to the waste liquid pool 1; a clear liquid overflow port 14 is arranged on the multistage sedimentation tank 13; the clear liquid overflow port 14 is connected to a waste liquid tank and a drainage system in a plant area.
The parking platform 16 can typically park two cars side by side, which also means that there should be two filler pipes 4.
In practical application, the tank body of the cement tank truck is not necessarily cleaned by clear water, generally, the impurities in the cement tank truck can be cleaned by only muddy water with not particularly high concentration, and the purpose of cleaning the tank body of the cement tank truck is to remove residual cement slurry on the inner wall of the tank body and prevent the cement slurry from being hardened to the thickness of the tank body to be increased.
Based on the principle, the recycling mode of the in-tank cleaning waste liquid of the system is as follows: the liquid adding pipe 4 extracts waste liquid from the waste liquid pool 1 and injects the waste liquid into a tank body of the cement tank truck, the tank body cleaning waste liquid of the cement tank truck is injected into the liquid collecting tank 2 and enters the sand-stone separator 3 through the liquid flow passage 21 for sand-stone separation, the separated muddy water enters the waste liquid pool 1, and the waste liquid of the waste liquid pool 1 is supplied to concrete water-consuming equipment in a plant area besides the liquid adding pipe 4; since the concentration of muddy water increases as the washing operation of the car proceeds, it is very necessary to provide the second pipe 9. If the slurry concentration in the waste liquid tank 1 exceeds the preset concentration in a specific time, the waste liquid is firstly diluted through the clear liquid overflow port 14 of the multistage sedimentation tank 13, and the dilution of the waste liquid can be considered through the water replenishing pipe 10 if the water quantity of the multistage sedimentation tank 13 is insufficient in summer or other times. Through the design, the water resource can be repeatedly recycled, the water is saved, and the environment is protected.
The recycling mode of the vehicle surface cleaning waste liquid of the system is as follows: the multistage sedimentation tank 13 performs multistage sedimentation treatment on the vehicle surface cleaning waste liquid, generally speaking, the multistage sedimentation tank can be a three-stage sedimentation tank, an overflow port is arranged between every two stages of sedimentation tanks, clear liquid is obtained after sedimentation, and the clear liquid can be continuously or intermittently replenished into the waste liquid tank at different flow rates. This determines the slurry concentration of the tank wash effluent in the effluent tank, which is closely related to the vehicle wash volume.
Sometimes, too many vehicles are cleaned, which means that the concentration is increased quickly, and at this time, besides the water supplement of the multistage sedimentation tank 13, the water supplement pipe 10 is needed for water supplement, and meanwhile, a production control workshop in a factory is informed, waste liquid in the waste liquid tank is pumped to concrete water utilization equipment, and the concrete water utilization equipment is forbidden to drain the waste liquid tank.
In this embodiment, the liquid channel 21 is further connected with a flushing pipe 22, the liquid channel 21 is inclined downwards towards the direction of the sand-stone separator 3, and one end of the flushing pipe 22 is connected to an outlet of the submersible pump 7; the other end of the flushing pipe 22 is connected to the end of the liquid flow channel 21 remote from the sand separator 3. The function of the flushing pipe 22 is to ensure the smooth flow of the liquid flow path 21, and the water used for the flushing pipe is also from the waste liquid tank 1.
In this embodiment, the sand-stone separator 3 is provided with a sand outlet 31 and a stone outlet 32; in addition, the system also comprises a liquid discharge pipe 11, an outlet of the liquid discharge pipe 11 is connected to the waste liquid pool 1, an inlet of the liquid discharge pipe 11 is connected to concrete water utilization equipment in the plant area, and filter screens 12 are respectively arranged between the drainage ditch 5 and the waste liquid pool 1, between the clear liquid overflow port 14 and the waste liquid pool 1, and between the clear liquid overflow port 14 and the drainage system 15.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
