Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a linear screen 100 includes a screen frame 110 and a screen 120 disposed on the screen frame 110. The linear sieve 100 further includes a distributor 130 and a plurality of guide plates 140, the plurality of guide plates 140 are spaced along the length direction or the width direction of the screen 120 to partition the screen 120 into a plurality of sub-screens, the distributor 130 includes a distribution inlet 131, a distribution body 132, and a plurality of distribution outlets 133, and each of the plurality of distribution outlets 133 corresponds to at least one sub-screen.

Illustratively, as shown in fig. 1, the linear sieve 100 includes 3 baffles 140, and the 3 baffles 140 are spaced along the width direction of the screen 120, so that the screen 120 can be divided into 4 sub-screens, of course, a person skilled in the art may also have a greater number or a smaller number of baffles 140 according to actual needs, and specifically, the number may be determined according to actual needs, and the embodiment is not particularly limited. Illustratively, as shown in fig. 2, the distributor 130 includes 4 distribution outlets 133, and each distribution outlet 133 corresponds to one sub-screen, besides, those skilled in the art can design a greater or lesser number of distribution outlets 133 according to actual needs, and as some alternative options, the distribution outlets 133 may correspond to a plurality of sub-screens, or one sub-screen corresponds to a plurality of distribution outlets 133, or a part of the distribution outlets correspond to one sub-screen, another part of the distribution outlets correspond to a plurality of sub-screens, and so on, which is not particularly limited by the embodiment.

The operation of the exemplary linear screen 100 will now be described with reference to fig. 1 and 2.

When the material is screened, the material firstly enters the distributor 130 from a bin (not shown in the figure), and after being uniformly distributed by the distributor 130, the material respectively enters the corresponding sub-screens from the distribution outlets 133, so that the material can move forwards in the sub-screens, and the material can be screened in the sub-screens.

The rectilinear sieve of this embodiment, with the help of tripper and the guide plate that sets up, can be even to the preliminary distribution of material through the tripper, the material after the distribution is even gets into and sieves in each sub-screen cloth to can the greatly increased effective usable floor area of screen cloth, improve the screening efficiency of screen cloth, can effectively reduce simultaneously and tear and warp, reduce the change frequency of screen cloth, reduce rectilinear sieve's cost.

Illustratively, as shown in fig. 1, the plurality of baffles 140 are disposed at equal intervals along the width direction of the screen 120, so that the size of the screening channels formed by the sub-screens is consistent, the material entering the screen 120 can be further uniformly distributed, and the screening efficiency is improved. Besides, the plurality of baffles 140 may also be disposed at equal intervals along the length direction of the screen 120, and at this time, the sieving direction (moving direction) of the material is along the width direction of the screen 120, in this example, the number of the formed sub-screens may be effectively increased, but it is slightly insufficient that the sieving moving path of the material in each sub-screen is reduced, and therefore, a person skilled in the art may make a specific choice according to actual needs, and the embodiment is not limited in particular.

Illustratively, as shown in fig. 1, one end of the baffle 140 is connected to a corresponding side wall of the screen frame 110. Preferably, both ends of the baffle 140 are connected to the corresponding sidewalls of the screen frame 110. Like this, can set up guide plate 140 on reel 110 firmly to the situation that guide plate 140 was toppled over appears receiving the effort of the material that flows takes place, and then can improve screen cloth 120's screening efficiency, and can effectively reduce rectilinear sieve 100's maintenance cost.

Illustratively, as shown in fig. 1 and 2, the width dimension of the plurality of feed outlets 133 matches the length dimension or the width dimension of the screen 120. Specifically, when the baffles 140 are spaced along the length of the screen 120, i.e., the material screening channel is along the width of the screen 120, the width of the plurality of distribution outlets 133 matches the length of the screen 120. Accordingly, when the flow guide plates 140 are spaced apart in the width direction of the screen 120, that is, the material sieving channel is along the length direction of the screen 120, the width dimension of the plurality of material distributing outlets 133 matches the width dimension of the screen. In this way, it may be convenient to set the correspondence between the divided outlets 133 and the sub-screens, for example, it may be effectively ensured that the divided outlets 133 correspond to one sub-screen.

Illustratively, as shown in fig. 2, the material distributing body 132 has a material distributing cavity therein, and the distributor 130 further includes a plurality of partition plates 134, wherein the plurality of partition plates 134 are disposed in the material distributing cavity to divide the material distributing cavity into a plurality of sub-material distributing cavities; wherein, the inlet of each sub-distribution cavity in the plurality of sub-distribution cavities is communicated with the distribution inlet 131, and the outlet of each sub-distribution cavity in the plurality of sub-distribution cavities is communicated with the corresponding distribution outlet 133. Illustratively, as shown in fig. 2, the distributor 130 may include 3 partition plates 134, and the three partition plates 134 may divide the distribution chamber into 4 sub-distribution chambers, each sub-distribution chamber corresponding to one distribution outlet 133, so that the material may flow to the corresponding sub-screen through the corresponding distribution outlet 133 after being uniformly distributed through each sub-distribution chamber, thereby further effectively improving the screening efficiency.

Illustratively, as shown in fig. 2, the distributor 130 further includes a flow regulator 135, and the flow regulator 135 is disposed in the distribution cavity to regulate the flow of the material into each sub-distribution cavity, so as to further improve the screening efficiency.

It should be noted that, the specific structure of the flow regulating member 135 is not limited, for example, the flow regulating member 135 may include a plurality of flow regulating valves, and each of the plurality of flow regulating valves is disposed in the corresponding sub-distributing cavity. Of course, besides, those skilled in the art may select other flow rate adjusting structures according to actual needs, and the embodiment is not limited to this.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
