Description

New type sediment separation device

technical field

The utility model relates to the technical field of construction engineering equipment, and is a special novel sediment separation device.

Background technique

The sediment separator uses a cyclone to classify the sediment mixture. The sand in the mixture enters the vibrating screen through the cyclone, and is dehydrated by the vibrating screen. The mud and water in the mixture are directly discharged. The mud content of the sand released by the vibrating screen is too high to meet the requirements of construction sand, so it can only be discarded, causing environmental pollution and waste of resources; Direct transportation; the discharged mud-water mixture still contains sand, and the sediment separation effect is not good.

Utility model content

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a new type of sediment separation device, which effectively solves the problem of high water content in sand and high water content in muddy water caused by poor sand separation effect of current sediment separators. Sand and other issues.

The technical solution is that the utility model includes a base, which is characterized in that a water tank is installed on the base, a dewatering screen is connected above the water tank, a plurality of feeding pipes are connected on the dewatering screen, and the bottom of the water tank is connected to the slag through the slurry pump inlet pipe. The slurry pump and the slurry pump are connected to the cyclone through the outlet pipe, and the sand outlet and mud outlet of the cyclone are respectively connected to the dewatering screen and the return water tank, and the lower end of the reverse water tank is provided with an outlet pipe.

Compared with the prior art, the utility model has the beneficial effects as follows: 1) The cyclone and the slurry pump are improved, so that the cyclone and the slurry pump are more matched. The mud content of the sand discharged through the cyclone is lower, which can fully meet the national requirements for construction sand, so that resources can be utilized to the maximum extent, and the sand content of the discharged tail water is lower; 2) For this fine For sand with higher density, we have designed a special dewatering screen. The water content of the sand treated by the dewatering screen is lower, which is convenient for direct transportation by vehicle.

The structure of the utility model is simple and reasonable, and the technical scheme is put into production and used, so that the mud produced by piling and shield tunneling can be well treated, which not only reduces the waste of resources, but also reduces the pollution of the environment.

detailed description

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

Shown by Fig. 1 to Fig. 3, the utility model comprises a base 1, is characterized in that, a water tank 2 is installed on the base 1, the dehydration screen 3 is connected above the water tank 2, and a plurality of feeding pipes 4 are connected on the dehydration screen 3, and the water tank 2 The bottom is connected to the slurry pump 6 through the slurry pump inlet pipe 7, the slurry pump 6 is connected to the cyclone 9 through the upper water pipe 10, and the sand outlet and mud outlet of the cyclone 9 are respectively connected to the dewatering screen 3 and the return water tank 11 , The lower end of the water return tank 11 is provided with an outlet pipe 5 .

The dewatering screen 3 is a double-layer dewatering screen, and the dewatering screen includes a bottom dewatering screen 13 and an upper dewatering screen 12 .

The dewatering screen 3 is a linear vibrating screen.

The feed pipe 4 is connected to the bottom dewatering screen 13 .

The sand outlet of the cyclone 9 is connected to the upper dewatering screen 12 .

The slurry pump 6 is controlled by a motor 8 fixed on the base 1 .

The mesh of the upper dewatering screen 12 is smaller than the mesh of the bottom dewatering screen 13 .

When the utility model is in use,

The building materials are pumped into the feed pipe 4, and the feed pipe 4 evenly distributes the raw materials to the screen surface of the bottom dewatering screen 13 of the double-layer dewatering screen 3, and the bottom dewatering screen 13 removes the sieve holes larger than the bottom dewatering screen 13 from the raw materials. The particles are filtered out, and the remaining materials leak into the water tank 2. The slurry pump 6 pumps the material in the water tank 2 into the cyclone 9 through the outlet pipe 10 through the slurry pump inlet pipe 7, and the sediment is discharged through the cyclone 9. Separation is carried out, and the sand after separation enters on the upper dewatering screen 12 of the double-layer dewatering screen 3 by the sand outlet, and the muddy water mixture enters in the return water tank 11 from the water outlet, and is discharged by the outlet pipe 5 again.

The dewatering sieve 3 adopted in the utility model, through many tests, carries out the corresponding design according to the physical characteristics of building materials, the material of the selected vibrating screen, the size of the sieve hole of the screen surface, the diameter of the steel wire of the screen and the size of the vibrating screen. Vibration frequency conducts a large number of tests to obtain the parameters of the vibrating screen required for the corresponding building materials. When separating sediment, the corresponding vibrating screen can be selected according to the site conditions, so that the sand dehydration can be more thorough.

Due to the redesign of the dewatering screen 3, when selecting the slurry pump 6 and the cyclone 9, it should be selected according to the parameters of the on-site construction materials and the dewatering screen 3, so that the slurry pump 6 and the cyclone 9 are the same as the dewatering screen 3 Cooperate with each other to realize the complete separation of sediment.

Compared with the traditional sediment separator, the utility model has the following beneficial effects: 1) The cyclone and the slurry pump are improved, and after a large number of experiments, the cyclone and the slurry pump are more matched. The sand discharged through the cyclone has a lower mud content, which can fully meet the national requirements for construction sand, so that resources can be utilized to the maximum extent, and the sand content of the discharged tail water is lower; 2) For this fineness For higher sand, we have designed a special dewatering screen, and the sand treated by the dewatering screen has a lower moisture content, which is convenient for direct transportation by vehicle.
