Problems solved by technology

At present, the sand and gravel raw materials used to make concrete are often mixed with impurities, mostly wood chips, grass roots, and tree roots. Low and surface collection and scum appear during the sampling process
[0003] The current conventional solution to this problem is to manually pick up from the sand and gravel pile, which is very ineffective and time-consuming, and can only remove wood chips and impurities on the surface of the sand and gravel pile, and cannot fundamentally solve the problem , so the quality of concrete made of this kind of sand and gravel is not ideal, and it also brings negative impacts on production and quality to related enterprises

Embodiment 1

[0027] Such as figure 1 The shown device for separating impurities in sand and gravel includes: feed port 7 , conveyor belt 8 , impurity separator 5 , vibrating filter belt 2 , sand and gravel cleaning screen 4 , and gravel conveyor belt 1 . In this embodiment, the feeding port 7 is connected to the sand and gravel yard, and the feeding port 7 for conveying sand and gravel is connected to one end of the conveyor belt 8, and a large amount of sand and gravel without separated impurities in the sand and gravel yard are transported to the conveyor belt. On the belt 8, the other end of the conveyor belt 8 is connected with the entrance of the impurity separator 5, and the conveyor belt 8 sends sand and gravel from a lower place to a high place, and finally pours it from the entrance of the impurity separator 5.

[0028] The impurity separator 5 is equipped with an agitator 6, where the agitator 6 adopts a helical agitator 6, and the unseparated sandstone poured from the conveyor b...

Embodiment 2

[0035] Such as figure 2 A kind of device that is used to separate the impurity in sand and stone shown has the following characteristics compared with embodiment 1:

[0036] This embodiment includes: a mud stirring tank 10, a first mud tank 9 is provided under the vibrating filter belt 2, and the mud stirring tank 10 is connected with the first mud tank 9 and the impurity separator 5 respectively.

[0037] This embodiment also includes: a second mud pool 12 , a water receiving tray 13 is provided under the sand cleaning screen 4 , the water receiving tray 13 is connected to the second mud pool 12 , and the second mud pool 12 is connected to the mud mixing pool 10 .

[0038] This embodiment also includes a clear water pool 11 , which is connected to the mud mixing pool 10 .

[0039] In this embodiment, the spray water pipe 3 is connected to the clear water pool 11 .

[0040] In Example 1:

[0041] 1. The mud in the impurity separator 5 needs to be prepared and manually intr...

Abstract

The invention provides a device for separating impurities in dinas. The device comprises a feeding opening, a conveying belt, an impurity separating machine, a vibration filtering belt, a dinas cleaning sieve and a dinas conveying belt. The feeding opening for conveying dinas is connected with one end of the conveying belt, and the other end of the conveying belt is connected with an inlet of the impurity separating machine. An outlet of the impurity separating machine is connected with an inlet of the dinas cleaning sieve. An outlet of the dinas cleaning sieve is connected with the dinas conveying belt. The impurity separating machine is internally provided with a stirrer, contains separating media and is connected with one end of the vibration filtering belt. The other end of the vibration filtering belt is provided with an impurity discharging opening. The dinas processed through the device is free of impurities, the obtained concrete is good in quality and high in strength, and the situations of surface finishing and dross do not exist in the sampling process.

Description

technical field [0001] The invention relates to the application field of sand and gravel collection, in particular to a device for separating impurities in sand and gravel. Background technique [0002] The concrete commonly used in construction has an apparent density of 1950-2500Kg / m3, and is mainly prepared with sand and gravel as the main aggregate. It is the most commonly used material in civil engineering. Therefore, the quality of raw sand and gravel directly affects the quality of concrete. At present, the sand and gravel raw materials used to make concrete are often mixed with impurities, mostly wood chips, grass roots, and tree roots. Low and surface collection and scum appear during the sampling process. [0003] The current conventional solution to this problem is to manually pick up from the sand and gravel pile, which is very ineffective and time-consuming, and can only remove wood chips and impurities on the surface of the sand and gravel pile, and cannot fu...
