Embodiment 1

[0033] This example provides a multi-stage centrifugal concentration treatment device for waste slurry water, such as Figure 1-4 As shown, it includes an inner barrel 1 and an outer barrel 2. The inner barrel 1 is located inside the outer barrel 2. The shape of the barrel of the inner barrel 1 is straight and the width is 0.35m; the upper part of the inner barrel 1 is provided with a connecting rod 4, which is connected to the rotating motor The transmission shaft 6 of one 7 is connected, and the top of the inner barrel 1 is provided with a feeding mechanism 3, and the feeding structure includes a direct current pipeline 31, a corner pipeline 32, a direct current pipeline 2 33 and a corner outlet 34, and the upper part of the inner barrel 1 is provided with an inner barrel swirl outlet 5 , the inner barrel body 8 is a mesh structure, specifically composed of multi-layer screens, the aperture of which is 0.01-0.05mm; the total height of the outer cylinder 2 is 1.7m, and the wid...

Embodiment 2

[0036] This example provides a multi-stage centrifugal concentration treatment device for waste slurry water and its use method. The difference from Example 1 is that the height ratio of the upper, middle and lower parts of the outer cylinder is 2:5:2, and the remaining steps and parameters are the same.

Embodiment 3

[0038]This example provides a multi-stage centrifugal concentration treatment device for waste slurry water and its use method. The difference from Example 1 is that the height ratio of the upper, middle and lower parts of the outer cylinder is 2:5:5, and the remaining steps and parameters are the same.

Abstract

The invention discloses a multi-stage centrifugal concentration treatment device for waste slurry and a use method thereof. The device comprises an inner barrel and an outer barrel, the inner barrel is located in the outer barrel, a connecting rod is arranged on the upper portion of the inner barrel, the connecting rod is connected with a transmission shaft of a first rotating motor, a feeding mechanism is arranged on the top of the inner barrel, an inner barrel rotational flow outlet is formed in the upper portion of the inner barrel, a barrel body of the inner barrel is of a mesh structure, the outer barrel comprises an outer barrel upper portion, an outer barrel middle portion and an outer barrel lower portion, the outer barrel upper portion is provided with a clear water outlet, the outer barrel middle portion is provided with a waste slurry outlet, the outer barrel lower portion is provided with a waste slurry residue outlet, and the outer barrel is connected with a second rotating motor through a transmission device. The device has the characteristics of small occupied area, low cost, low energy consumption, high solid-liquid separation efficiency and easy operation in a use process; and according to the device, multi-stage separation of the waste slurry can be realized, different waste slurry products are obtained, high-efficiency and high-quality separation of the waste slurry is realized, and the disposal level, the utilization rate and the added value of the waste slurry are improved.

Description

technical field [0001] The invention relates to the technical field of centrifugal concentration treatment of waste slurry water, in particular to a multi-stage centrifugal concentration treatment device for waste slurry water and a use method thereof. Background technique [0002] With the development of construction, the output of ready-mixed concrete in my country is increasing year by year, and every 1m produced 3 Concrete, mixing plants will produce an average of 0.04 tons of plastic waste, and the annual processing of waste in mixing plants will exceed 100 million tons nationwide. Due to the long-term lack of scientific supporting treatment facilities and disposal processes, the treatment of waste slurry water has always been a technical problem faced by concrete mixing plants for a long time. The current general methods are sedimentation filter press method, homogenization method, etc. The mud cake produced after the sedimentation and filtration method is directly tr...
