Problems solved by technology

[0002] Now the papermaking industry generally uses grass such as wheat straw and rice straw as raw materials for papermaking. The first step of the process is to crush the grass, and then transport the crushed grass to the next process for processing; in order to make the subsequent process go smoothly, It is necessary to remove the heavy impurities mixed in the grass slices so as not to damage the mechanical equipment; in the prior art, only the principle of magnetic adsorption is used to remove the magnetophilic impurities, such as iron nails, iron sheets, etc., during the transportation process, while sand, etc. Impurities are not easy to remove, and such grass flakes containing impurities will also damage mechanical equipment and reduce the quality of papermaking

Embodiment 1

[0017] Embodiment one: if figure 1 As shown, a kind of grass chip remover includes a tank body 1 filled with water inside, a separation device 2 that separates water and grass chips at the rear of the tank body 1, and a water collection device 4 located below the separation device 2. The collection device 3 for collecting the grass pieces separated by the separation device 2, the water collection device 4 and the tank body 1 are connected by a pipeline 6, and the water collection device 4 is provided on the pipeline to transport the water in the water collection device 4 to The circulating water pump 5 in the tank body 1; the present embodiment utilizes the principle of buoyancy to suspend the grass slices on the surface of the water, while the heavy impurities sink to the bottom of the water. The grass flakes are brought into the separation device, and the grass flakes after removing impurities go to the next process, and the outflowing water flows back to the flotation tank ...

Embodiment 2

[0021] Embodiment two: if figure 2 As shown, the technical solution of this embodiment is basically the same as that of Embodiment 1, except that a feeding device 14 that promotes the movement of forage to the separation device 2 is added above the tank body 1 filled with water. The material shifting device 14 includes a power unit (not shown in the figure), two pulleys 14a, a belt 14b installed on the two pulleys 14a, and a material shifting claw 14c is installed on the belt 14b. The power unit preferably adopts an electric motor.

[0022] Certainly, the described material shifting device 14 can also adopt a power device, two sprockets 14a, a chain 14b installed on the two sprockets 14a, and a material shifting claw 14c is installed on the described chain 14b.

Embodiment 3

[0023] Embodiment three: as image 3 As shown, the technical solution of the present embodiment is basically the same as that of the second embodiment, the difference is that the shifting device 14 includes a power device and a shifting wheel 14d, and the shifting claw 14e is installed on the shifting wheel 14d . There can be multiple setting devices.

Abstract

The invention discloses a de-burring machine used to process weed, which is characterized in water tank containing water in it, debonding unit locating at the rear of water tank to separate water with weed, capitation locating under the debonding unit, weed gathering device collecting weed from debonding unit, said capitation connecting with water tank via pipes, and circulating pump being equipped on said pipes to transport water in capitation to water tank. The invention makes use of buoyant force of water and gravity to separate weed and impurity. The invention has the advantages of simple structure, saving water and improving purity of the forage fodder.

Description

technical field [0001] The invention relates to a papermaking machine, in particular to a machine for removing heavy impurities in crushed grass slices. Background technique [0002] Now the papermaking industry generally uses grass such as wheat straw and rice straw as raw materials for papermaking.
