Separation screen module

Abstract

The invention provides a separation screen module. The separation screen module comprises a separation screen, and a conveying mechanism connected with the separation screen. The separation screen module is characterized in that a first end of the separation screen is connected with a feed spiral conveying mechanism; a second end of the separation screen is connected with a first discharge spiralconveying mechanism; a second discharge spiral conveying mechanism is connected under the separation screen; and the connected places of the separation screen with the feed spiral conveying mechanism,the first discharge spiral conveying mechanism and the second discharge spiral conveying mechanism are all of closed connecting structures. The separation screen module can achieve effective dust prevention and higher automation degree and production efficiency.

Description

technical field [0001] The invention relates to the technical field of material separation, in particular to a separation screen assembly. Background technique [0002] Separator is a common material separation equipment, widely used in many industries. For example, in the papermaking industry, straw and other forages are crushed by a pulverizer into a mixture of fibrous and non-fibrous materials. The fibrous material is used as a raw material in the papermaking process and should enter the next process instead of fiber. The material is waste and should not enter the next process. Therefore, in order to facilitate the transportation of fiber materials to the subsequent process, it is necessary to use a separating screen to separate the mixture of crushed materials. A sieve is arranged in the separation sieve, and the broken material can be separated from the fibrous material and the non-fibrous material through the screening of the sieve. However, since the pulverizer and...

Problems solved by technology

However, due to the continuous operation of the pulverizer and the separating screen, non-fibrous materials are constantly falling from the screen, and it is usually necessary to manually remove them regularly or continuously to prevent accumulation, which is very time-consuming and labor-intensive

At the same time, since the non-fibrous material is a powdery crushed material, after using the separating screen to separate the crushed material mixture, when the separated non-fibrous material falls from the screen, if it falls into an open space, it will be very easy in the process. The phenomenon of flying dust makes the environment of the production workshop worse, and there are even potential fire safety hazards. It is necessary to clean the workshop regularly, which is time-consuming and labor-intensive. At the same time, flying dust will also cause certain pollution to the atmospheric environment, which does not meet the requirements of environmental protection; Equally, because the fibrous material is also a broken material, when the separated fibrous material falls from the discharge port of the separating screen, if it falls in an open space, the above-mentioned problems also exist in the process of falling; in addition, the open space also has It is easy to cause the material to fall from the outlet to the ground, causing waste
