Description

TECHNICAL FIELD

[0001] The utility model relates to concrete production technical field, especially a kind of concrete waste residue recycling system after concrete tank truck washes tank. BACKGROUND

[0002] After concrete production, it needs to use concrete mixer truck to transport, and the concrete tank truck after use needs to be washed in time to prevent concrete from condensing in tank, and remove a small part of concrete that has condensed into block. High-pressure water gun is needed in the process of washing tank to clean the tank, and waste water and residue are discharged at discharge port. This process needs to consume a lot of water, and the mixture of water and concrete is not easy to handle, which can easily cause environmental pollution and is difficult to recycle. SUMMARY

[0003] The utility model provides a kind of concrete waste residue recycling system after concrete tank truck washes tank, and the residue of concrete and water generated after washing tank is recycled.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a kind of concrete waste residue recycling system after concrete tank truck washes tank, including the collecting hopper for collecting waste, the lower end of collecting hopper is inserted into overflow bucket, the upper end of overflow bucket is opened, for discharging water in waste material;The lower end of overflow bucket is connected with the feed end of screw conveying device, for discharging concrete block and stone in waste material, and the screw conveying device is inclined upward.

[0005] Preferably, a belt conveyor is arranged below the discharge port of the screw conveying device, for conveying solid waste to a waste collection tank.

[0006] Preferably, a scraper is arranged below the discharge end of the belt conveyor.

[0007] Preferably, a sedimentation tank is arranged below the overflow bucket and below the discharge port of the screw conveying device, for collecting waste liquid.

[0008] Preferably, a discharge port is arranged at the lower end of the overflow bucket.

[0009] Preferably, the belt conveyor is inclined upward along the conveying direction.

[0010] The utility model provides a kind of concrete waste residue recycling system after concrete tank truck washes tank, which can quickly separate waste liquid and waste residue while washing tank, meet the characteristics of large water flow in the process of washing tank, and after recycling waste liquid and waste residue, they are treated and reused. The ecological environment is protected, and the production cost is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0011] The utility model will be further described below in connection with the drawings and examples:

[0012] Figure 1 It is structural diagram of the utility model. PREFERRED EMBODIMENT

[0013] As Figure 1 shown, a kind of concrete tank truck washes concrete waste residue recycling system after tank, including the aggregate hopper 1 for collecting waste, the lower end of aggregate hopper 1 is inserted into overflow bucket 2, the upper end of overflow bucket 2 is opened, for discharging water in waste;The lower end of overflow bucket 2 is connected with the feed end of screw conveyor 3, for discharging concrete block and stone in waste, the screw conveyor 3 is inclined upwardly arranged.

[0014] Preferably, the lower of the discharge port of screw conveyor 3 is equipped with belt conveyor 4, and the belt conveyor 4 is used for conveying solid waste to waste collection tank 5.

[0015] Preferably, the lower of the discharge end of belt conveyor 4 is equipped with scraper 6.

[0016] Preferably, the lower of overflow bucket 2 and the lower of the discharge port of screw conveyor 3 are equipped with sedimentation tank 7 for collecting waste liquid.

[0017] Preferably, the lower end of overflow bucket 2 is equipped with discharge port 8. Finally, overflow bucket 2 can no longer overflow after washing is completed, at this time, open the discharge port 8, and discharge the waste in overflow bucket 2.

[0018] Preferably, the belt conveyor 4 is inclined upwardly arranged along the transmission direction. Make the waste liquid remaining in the discharge port of screw conveyor 3 and the belt conveyor 4 can flow back to the sedimentation tank 7.

[0019] When using, the waste generated in the tank washing process is collected into the aggregate hopper 1, and solid-liquid separation is realized through the overflow bucket 2, the waste liquid overflows into the sedimentation tank 7, and after sedimentation, subsequent flocculation, filtration and other treatments are carried out. The waste residue enters the belt conveyor 4 after screw conveying, and finally enters the waste collection tank 5, and realizes recycling after subsequent drying treatment.

[0020] The above examples are only preferred technical solutions of the utility model, and should not be regarded as limitation of the utility model. The protection scope of the utility model should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features recorded in the claims. That is, the equivalent replacement improvement within this range is also within the protection scope of the utility model.
