[ detailed description ] embodiments
The following examples are further to explain and supplement the present invention, and do not constitute any limitation to the present invention.
As shown in fig. 1, the automatic concrete slurry recycling system of the present invention includes a slurry tank 10, a sedimentation tank 20, a clean water tank 30, a sand-stone separator 40, a stirrer 50, a filter press 60, and a slurry pump 70.
The sand separator 40 is used for separating sand from sewage, and a known sand separator 40 can be used. The sewage generated by flushing is introduced into a sand-stone separator 40, which can separate large-particle sand-stone in the sewage, and the separated large-particle sand-stone can be used as a raw material for concrete production and can be continuously utilized. The liquid from which the sand and stone are separated is slurry-water slurry containing powder, and is introduced into the slurry tank 10 through the drainage ramp.
The slurry tank 10 is used for collecting slurry. The slurry tank 10 can be constructed according to the known art, and can be sized as desired.
Since the slurry contains concrete powder, a stirrer 50 is provided above the slurry tank 10 in order to prevent the concrete powder from being coagulated. The stirrer 50 is vertically arranged above the slurry tank 10. The stirrer 50 is selected and installed according to the known art. Under the stirring of the stirrer 50, the slurry in the slurry water can be uniformly dispersed, thereby preventing coagulation thereof.
The sedimentation tank 20 is used for performing sedimentation filtration on the slurry water in the slurry tank 10 so as to precipitate the particulate matters to obtain relatively clear water.
The sedimentation tank 20 is arranged between the slurry tank 10 and the clean water tank 30 and is respectively communicated with the sedimentation tank 20 and the clean water tank 30. In this embodiment, the sedimentation tank 20 includes an upper partition 21 and a lower partition 22. The upper partition 21 is disposed on the top of the settling tank 20, and the bottom of the upper partition 21 is spaced from the bottom of the lower partition 22. The lower partition plates 22 are arranged at two sides of the upper partition plate 21 at intervals, and the top of the lower partition plate 22 is spaced from the top of the upper partition plate 21 by a certain distance, so that the upper partition plate 21 and the lower partition plate 22 are arranged in a staggered manner to form a liquid flow channel. The number of the upper and lower partitions 21 and 22 may be set as desired.
Since the slurry tank 10 is communicated with the sedimentation tank 20, the slurry in the slurry tank 10 can enter the sedimentation tank 20. In this embodiment, the upper portion of the slurry tank 10 is communicated with the upper portion of the sedimentation tank 20, and in other embodiments, the bottom of the slurry tank 10 may be communicated with the bottom of the sedimentation tank 20. When thick liquid gets into sedimentation tank 20, the particulate matter in the thick liquid can subside along the baffle owing to the effect of blockking of dead weight and upper baffle 21, lower baffle 22, descends to sedimentation tank 20's bottom to it contains the particulate matter greatly reduced to make to flow to the liquid in clean water basin 30 from sedimentation tank 20, in order to obtain comparatively clear water and can be used to the vehicle and wash and the place washes.
In order to prevent the slurry in the slurry from condensing at the bottom of the sedimentation tank 20 and reduce the workload of manually cleaning the sedimentation tank 20, in the embodiment, the slurry pump 70 is adopted to automatically extract the slurry at the bottom of the sedimentation tank 20 for recycling. Specifically, a transverse electric control gate 23 is arranged between the lower partition plates 22. The electrically controlled sluice 23 is perpendicular to the lower partition 22 and divides the settling tank 20 into an upper flow zone 24 and a number of settling zones 25 at the bottom. When the electrically controlled gate 23 is closed, the flow zone 24 is isolated from the settling zone 25, and the slurry pump 70 is used to pump the slurry from the settling zone 25. When the electrically controlled gate 23 is opened, the flow area 24 and the settling area 25 are communicated, and the slurry in the settling area 25 can be settled to the settling area 25.
A slurry outlet is arranged at the bottom of the settling zone 25, and a control valve 26 is arranged at the slurry outlet. The slurry outlet is connected with a conveying pipeline 27. The transfer pipe 27 may be arranged with reference to the art for transferring slurry with a high concentration of particulate matter. The control valve 26 is used for controlling the opening and closing of the slurry outlet, so that the slurry can be prevented from flowing into the conveying pipeline 27 and being condensed when the slurry pump 70 is not operated, and the conveying pipeline 27 is prevented from being blocked. The control valve 26 may be a known electrically controlled valve.
The electronically controlled gate 23 is timed to open and close to facilitate slurry extraction from the settling zone 25 and to avoid slurry condensation. In order to automatically control the electric control gate 23 and the slurry pump 70, the system is also provided with a control device. The electric control gate 23, the control valve 26 and the slurry pump 70 are respectively electrically connected with the control device. Under the control of the control device, the electrically controlled gate 23 is closed at regular time. When the electrically controlled gate 23 is closed, the slurry pump 70 and the control valve 26 are automatically opened, and the slurry pump 70 can pump the slurry in the settling zone 25 to the filter press 60 through the conveying pipeline 27. When the electric control gate 23 is opened, the control valve 26 and the slurry pump 70 are automatically closed in a delayed time mode, and the slurry in the settling area 25 is stopped being extracted.
The delay time of the automatic delay closing of the control valve 26 and the slurry pump 70 can be set according to requirements.
The time interval for closing the electrically controlled shutter 23 at regular time can be set as required.
The linkage arrangement among the control device, the control valve 26, the electric control gate 23 and the slurry pump 70 can be designed by referring to the known technology.
Further, in order to prevent the slurry from accumulating on the electronically controlled gate 23 when the electronically controlled gate 23 is closed, and thus the opening and closing of the electronically controlled gate 23 are affected, a known vibration device may be disposed on the surface of the electronically controlled gate 23, which may prevent the slurry from condensing on the surface of the electronically controlled gate 23, and may facilitate shaking off the slurry accumulated on the electronically controlled gate 23. The vibration device may be provided by a known technique.
The slurry pump 70 may be a known slurry pump 70, and the connection between the slurry pump and the transfer pipe 27 may be made by referring to a known technique. The slurry pump 70 is connected at its input to the transfer pipe 27 and at its output to the filter press 60, so that it can pump the slurry water from the settling zone 25 into the filter press 60 for separation.
The filter press 60 may optionally employ known solid-liquid separation equipment that separates particulate matter from liquid in the slurry to yield a solid isolate and a filtered supernatant. The separated solid isolate, which is mainly a concrete raw material, can be recycled and used in the production and processing of concrete. The clear liquid separated therefrom, which is available for daily washing because the concrete material has been removed, can be introduced into the clear water tank 30 through a pipe.
The filter press 60 is generally provided with an overflow port, the overflow port is connected with an overflow pipe 61, and an outlet of the overflow pipe 61 is arranged above the slurry tank 10, so that the overflowed slurry can flow back to the slurry tank 10 for collection.
The clean water tank 30 is used to collect the clarified liquid for convenient use in flushing. The clean water tank 30 may be constructed in accordance with a known technique, and may be sized as needed.
The clean water tank 30 is communicated with the sedimentation tank 20, and after the sedimentation tank 20 sediments the slurry, the clarified liquid flows into the clean water tank 30 to be collected. Further, the clear liquid produced by the filter press 60 after processing the slurry-water slurry also flows into the clear water tank 30.
Therefore, just formed the utility model discloses an automatic recovery system of concrete thick liquid water, its theory of operation is:
the sewage from the flushing of the construction vehicle is first introduced into a sand separator 40 for sand filtration. The filtered sand and stone are recycled and used as concrete raw materials. The slurry water after the sand and stone separation is introduced into the slurry water pool 10 through the drainage ramp and collected.
The stirrer 50 in the slurry tank 10 intermittently stirs the slurry to prevent the slurry from being coagulated.
Because the slurry tank 10 is communicated with the sedimentation tank 20, the slurry uniformly dispersed in the slurry tank 10 flows into the sedimentation tank 20 for sedimentation. After the slurry flows into the sedimentation tank 20, particles such as slurry in the slurry settle to the sedimentation zone 25 due to the self-weight and the blocking effect of the partition plates, so that the liquid flowing from the sedimentation tank 20 to the clean water tank 30 is relatively clear.
The slurry settled in the settling zone 25 is pumped by the slurry pump 70 to the filter press 60 for treatment. Under the automatic control of the control device, the electrically controlled gate 23 is closed at regular time, so that the slurry pump 70 can extract the slurry in the settling zone 25 at regular time.
When the slurry water slurry with a high concentration is pumped to the filter press 60, the filter press 60 performs solid-liquid separation, the separated solid can be used for concrete production, and the separated liquid flows into the clean water tank 30.
The clean water collected in the clean water tank 30 is clear because it removes the substances such as sand, concrete slurry, etc., and thus, it can be used for washing the construction site and the construction vehicle. The water generated by flushing can flow into the slurry pool 10 to form a circulating system, so that the water in the slurry can be reused for flushing, and the separated solid slurry can be used as a raw material to be added into a corresponding project, thereby avoiding serious pollution to the environment caused by direct discharge and saving a large amount of water.
While the invention has been described with reference to the above embodiments, the scope of the invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the invention.
