Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] It also includes a frame 7, a dust collection mechanism with a suction fan 8 is arranged on the frame 7, the dust collection mechanism includes a suction head 9 and two barrier covers 2, the suction head 9 is installed on the air inlet pipe of the suction fan 8, the dust filter screen 10 is installed on the air outlet pipe of the suction fan 8, support ears 21 are installed on both of the two barrier covers 2, in order to facilitate the disassembly of the two barrier covers 2 and then facilitate the maintenance of the vibrating screen, the support ears 21 are threadedly connected by bolts 3, and a dust outlet 20 is opened on one of the barrier covers 2; the barrier cover 2 is a transparent cover, and the operator can observe the working condition of the vibrating screen 1 through the transparent cover.

[0021] In this embodiment, the two barrier covers 2 are placed on the top of the vibrating screen 1. The vibrating screen 1 is a prior art, and the working principle will not be elaborated here. The vibrating screen 1 is installed on the foundation, and slots 22 are opened on the tops of the two barrier covers 2.

[0022] In this embodiment, the feed bin 40 is installed at the top of the vertical cylinder 42, the cover plate 41 is hinged on the feed bin 40, the vertical cylinder 42 is penetrated by a slot 420 on one side, and the plug board 6 is inserted into the slot 420.

[0023] In this embodiment, racks 7 are installed on both sides of the vertical cylinder 42 corresponding to each other, and the racks 7 are fixed to the foundation by expansion screws. A placement plate is installed on one of the racks 7, and a staircase is installed on the other rack 7. Figure 1 It is known that, however, in the attached drawings of the specification Figure 1 It is not marked in the figure, and the purpose of setting the stairs is mainly to facilitate the operator to load materials. A suction fan 8 is installed on the placement plate, and the suction head 9 is located above the dust outlet 20.

[0024] In this embodiment, the suction fan 8, cylinder 5 and vibrating screen 1 are all connected to an external power supply. In order to prevent the vibration of the vibrating screen 1 from driving the barrier cover 2 to vibrate, if the cavity formed by the slot 22 contacts the vertical cylinder 42, it is very likely to affect the vibration effect of the vibrating screen 1 moving left and right. The vertical cylinder 42 is located in the cavity formed by the two slots 22; the working stroke of the cylinder 5 is set by the controller.

[0025] The use method and advantages of the utility model: When the screening device for titanium dioxide production is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the operator pours titanium dioxide from the feed bin 40 to fill it up, and covers it with the cover plate 41. At this time, the cylinder 5 is in a retracted state, and the insert plate 6 is inserted into the cavity of the vertical cylinder 42, so that the titanium dioxide will not fall down;

[0027] When it is necessary to screen the titanium dioxide, the operator starts the cylinder 5, the suction fan 8 and the vibrating screen 1 simultaneously. The output end of the cylinder 5 extends from the input end, driving the plug plate 6 to move horizontally and leave the cavity of the vertical cylinder 42. At this time, the titanium dioxide in the feeding assembly 4 will be diverted from the vertical cylinder 42 and finally from the diverter cylinder 43 to the vibrating screen 1. At this time, the vibrating screen 1 works to screen the titanium dioxide.

[0028] The controller sets the working time of the cylinder 5, for example, it is extended for 2 seconds and then resets. At this time, the cylinder 5 retracts and resets, so that the plug plate 6 is inserted into the cavity of the vertical cylinder 42. The insertion of the plug plate 6 then blocks the titanium dioxide in the vertical cylinder 42 from continuing to fall. According to the above description, the set plug plate 6 plays an opening role, so that the titanium dioxide can be dumped at intervals. At the same time, the diversion cylinder 43 can make the titanium dioxide fall on the vibrating screen 1 in different directions, thereby replacing the hard work of manually pouring on the vibrating screen 1 with a spoon or other tools, and also greatly increasing the work efficiency;

[0029] Two barrier covers 2 provided on the vibrating screen 1 are also provided with a dust outlet 20 on one of the barrier covers 2. This is mainly to ensure that the dust generated during the pouring of titanium dioxide and the operation of the vibrating screen 1 can only be discharged through the dust outlet 20. At the same time, the operation of the suction fan 8 adsorbs the dust discharged from the dust outlet 20 through the suction head 9, and discharges the air from the dust filter net 10 to adsorb the dust. This not only avoids environmental pollution caused by dust, but also reduces the risk of surrounding operators inhaling dust and getting sick.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
