[0006] A plurality of filter tubes are installed with holes on the composite filter plate at the discharge port side, and the filter tubes are connected to an automatic liquid drain tank through pipelines, and the automatic liquid drain tank is connected to a vacuum pump;

[0007] The vacuum pump controls the formation of negative pressure in the automatic liquid drain tank, and the water in the cone part is filtered and discharged through the filter tube.

[0008] As an improvement, the filter tube comprises a cylindrical tube body, a filter cloth is installed on the top of the tube body, and filter holes are opened on the side wall of the tube body.

[0009] As an improvement, the filter tube is vertically installed on the composite filter plate.

[0010] As an improvement, the composite filter plate includes a perforated steel plate, a filter screen and a plastic perforated plate from the outside to the inside, the filter screen is laid on the perforated steel plate, and the plastic perforated plate is placed on the filter screen and fixed to the perforated steel plate.

[0011] As an improvement, the plastic orifice plate adopts PP plate or PE plate.

[0012] As an improvement, every two or four dehydration bins form a group, and each group of dehydration bins is connected to a belt conveyor.

[0013] Compared with the prior art, the suction filtration and dehydration silo of the present invention can completely isolate quartz sand from contact with iron, and also avoid contamination from the bucket and tire, silo concrete, etc. when the material is transported by a forklift after entering the warehouse, and adheres to the principle of "materials not falling to the ground". The suction filtration and dehydration silo is easy to operate and occupies a small area, which can greatly reduce the area occupied by the production line, improve production efficiency, and reduce production costs.

[0018] The following embodiments are further descriptions of the content of the present invention as an explanation of the technical content of the present invention, but the essential content of the present invention is not limited to the following embodiments. Ordinary technicians in this field can and should know that any simple changes or replacements based on the essential spirit of the present invention should fall within the scope of protection required by the present invention.

[0019] like Figure 1 , Figure 2 As shown, a quartz sand suction filtration dehydration silo includes a dehydration silo 1, wherein a cone portion 2 is provided at the lower end of the dehydration silo;

[0020] The bottom center of the cone part 2 is provided with a discharge port 5, which is controlled by an electric valve; the bin wall of the cone part 2 adopts a composite filter plate 3, which includes a perforated steel plate, a filter screen and a plastic perforated plate from the outside to the inside, the filter screen is laid on the perforated steel plate, and the plastic perforated plate is placed on the filter screen and fixed to the perforated steel plate, so as to effectively prevent material contamination;

[0021] A plurality of filter tubes 4 are installed on the composite filter plate 3 at the side of the discharge port 5. Preferably, a hole-shaped cavity is provided on the composite filter plate 3, and the filter tubes 4 are placed in the hole-shaped cavity and fastened to the composite filter plate 3 by bolts; the filter tubes 4 are connected to the automatic liquid drain tank 7 through the pipeline 6, and the automatic liquid drain tank 7 is connected to the vacuum pump 8;

[0022] The vacuum pump 8 controls the formation of negative pressure in the automatic drain tank 7 , and the water in the cone part 2 is filtered and discharged through the filter tube 4 .

[0023] As an improvement of the embodiment, Figure 2 As shown, the filter tube 4 includes a cylindrical tube body 41, which is made of porous iron-free materials such as PP or PE. A filter cloth 42 is installed on the upper end of the tube body 41, and the lower end is connected to the pipeline 6.

[0024] As an improvement of the embodiment, the filter tube 4 is vertically installed on the composite filter plate 3, which is more convenient to install and use.

[0025] As an improvement of the embodiment, the dehydration bins 1 are grouped in two or four units, and a belt conveyor 9 is installed below the discharge port 5 at the bottom of each group of dehydration bins 1 so that the belt conveyor 9 can receive and transport the products of each dehydration bin 1 .

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention can use two or four dehydration bins 1 as a group according to the output, and use the filter holes of the composite filter plate 3 on the cone part 2 at the lower end of the dehydration bin 1 to filter out water. The dehydration time is about 12 hours, and the quartz sand with a water content of 25% can be dehydrated to about 8% (depending on the temperature, particle size, and storage capacity).

[0027] If dehydration needs to be accelerated, the vacuum pump 8 is turned on, and the filter tube 4 is used in conjunction with the automatic drain tank 7 to discharge the water through negative pressure filtration, thereby greatly reducing the dehydration time and dehydration effect. The dehydration time is about 5 hours and the quartz sand with a water content of 25% can be dehydrated to about 8% (depending on the temperature, particle size, and storage capacity).

[0028] The suction filtration and dehydration silo of the present invention can adopt different dehydration methods according to production needs, so as to achieve a rapid dehydration effect, thereby shortening the production cycle, reducing the production cost of the lower production process (drying), and also increasing the drying output.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
