Furthermore, a wear-resistant rubber layer is arranged on one side of the mechanical mud scraping rake, which is abutted against the inner wall of the concentration tank.

Through adopting above-mentioned technical scheme, the setting of wear-resisting rubber layer can avoid machinery mud scraping harrow and thickener inner wall to take place direct friction, avoids machinery mud scraping harrow damage and influences thickener work efficiency.

Furthermore, the mechanical mud scraper and one end of the concentrated pool inner wall which is connected with the mechanical mud scraper are obliquely arranged, and the higher end of the mechanical mud scraper faces to the movement direction of the mechanical mud scraper.

Through adopting above-mentioned technical scheme, be the slope setting with the one end of mechanical mud scraper and concentrated pond inner wall butt, promote the waste residue downwards when the mechanical mud scraper of can being convenient for scrapes mud to the thickener inner wall to the waste residue of being convenient for leaves the thickener and gets into in the filter-press.

Furthermore, a stirring device is arranged in the wastewater collecting tank.

Through adopting above-mentioned technical scheme, agitating unit's setting can avoid the useless thick liquid to take place to harden bottom the waste water collecting pit.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) through the arrangement of the thickener, the waste slurry precipitated in the waste water collecting tank enters the thickener through the slurry inlet pipe, the waste slurry is further precipitated in the thickener, and the water content in the waste slurry is reduced, so that the waste slurry amount treated by the filter press is reduced, and the working efficiency of the filter press is improved;

(2) through the arrangement of the bidirectional grouting pump, clear water is injected into the thickener through the bidirectional grouting pump, so that the thick slurry at the bottom of the pond is automatically beaten reversely to prevent the thick slurry from hardening;

(3) through agitating unit's setting, can avoid the useless thick liquid to take place to harden bottom the waste water collecting pit.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A concrete waste slurry treatment system is shown by referring to fig. 1 and 3 and comprises a waste water collecting pool 1 and a filter press 2, wherein a slurry inlet pipe 3 with one end positioned at the bottom of the waste water collecting pool 1 is installed in the filter press 2, the other end of the slurry inlet pipe 3 is communicated with a thickener 4, and a first slurry outlet pipe 5 is communicated between the bottom of the thickener 4 and the filter press 2.

Further, the thickener 4 includes a thickening tank 41 and a mechanical rake 42. The mechanical scraper 42 can prevent the waste slag from adhering to the inner wall of the concentration tank 41 for a long time, thereby reducing the working efficiency of the thickener.

Referring to fig. 2 and 3, a first pneumatic valve 6 is installed in the first slurry outlet pipe 5, a second slurry outlet pipe 7 is communicated with the side wall of the first slurry outlet pipe 5 and is positioned at the upper end of the pneumatic valve, and a slurry outlet water pump 8 is installed in the second slurry outlet pipe 7. When thick liquid that forms 4 bottoms of thickener flowed into pressure filter 2 through first play thick liquid pipe 5, closed first pneumatic valve 6 and started out thick liquid water pump 8, took thick liquid through second play thick liquid pipe 7 for moisten the pipe to the pump truck, thereby need not use pump truck moistening pipe agent alone to moisten the pipe to the pump truck, reduced the manufacturing cost of concrete.

Furthermore, the slurry outlet water pump 8 is a bidirectional grouting pump, when the thick slurry at the bottom of the concentration tank 41 is hardened, clear water is injected into the thickener 4 through the bidirectional grouting pump and the second slurry outlet pipe 7, so that the hardened thick slurry is broken, and the bottom of the concentration tank is prevented from being blocked.

It is worth mentioning that the upper end of the side wall of the first slurry outlet pipe 5 and the second slurry outlet pipe 7 is communicated with a clean water pipe 9, and a second pneumatic valve 10 is installed in the clean water pipe 9. When thick liquid silts up in first play thick liquid pipe 5, open second pneumatic valve 10, break away thick liquid through the clear water to avoid thick liquid to take place to harden in first play thick liquid pipe 5 and lead to taking place to block up in the first play thick liquid pipe 5.

Referring to fig. 3, in order to prolong the service life of the mechanical scraper 42, a wear-resistant rubber layer 11 is installed on the side of the mechanical scraper 42, which is in contact with the inner wall of the thickening tank 41.

Furthermore, the end of the mechanical scraper 42 abutting against the inner wall of the thickening tank 41 is inclined, and the higher end faces the movement direction of the mechanical scraper 42. The inclined arrangement of the mechanical mud scraper 42 and the abutting end of the inner wall of the concentration tank 41 can facilitate the downward pushing of the waste residue when the mechanical mud scraper 42 scrapes the mud on the inner wall of the thickener 4, thereby facilitating the waste residue to leave the thickener 4 and enter the filter press 2.

It is worth mentioning that, referring to fig. 1, a stirring device 12 is installed in the wastewater collection tank 1, and the stirring device 12 can prevent the waste slurry from hardening at the bottom of the wastewater collection tank 1.

The utility model discloses a working process and beneficial effect as follows: the waste slurry after precipitation in the waste water collecting pool 1 enters the thickener 4 through the slurry inlet pipe 3, and the waste slurry is further precipitated in the thickener 4, so that the water content in the waste slurry is reduced, the waste slurry amount treated by the filter press 2 is reduced, and the working efficiency of the filter press 2 is improved.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
