Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Depend on Figures 1 to 4 This invention discloses a filtration device for negative pressure conveying of silica powder, comprising a filter body 1 connected in series with a feed pipe 2 of a negative pressure conveying device. The filter body 1 consists of an outer shell 3, a flow-diverting component 4, a coarse filter component 5, and a fine filter component 6. The flow-diverting component 4, the coarse filter component 5, and the fine filter component 6 are all fixedly connected inside the outer shell 3. The coarse filter component 5 is located on top of the flow-diverting component 4, and the fine filter component 6 is located on top of the coarse filter component 5. Both the coarse filter component 5 and the fine filter component 6 consist of a rubber ring 7 and a filter screen. 8. The vibrating motor 9 and the wiring harness 10 are combined. The rubber ring 7 is fixedly connected to the inner surface of the outer shell 3. The filter screen 8 is fixedly connected to the inside of the rubber ring 7. The vibrating motor 9 passes through the center of the filter screen 8 and is fixedly connected to the filter screen 8. The wiring harness 10 passes through the outer shell 3 and is connected between the vibrating motor 9 and the control system of the negative pressure conveying device. A rubber edge 11 is fixedly provided on the side of the top of the rubber ring 7. The rubber edge 11 and the rubber ring 7 are integrally formed. The rubber edge 11 and the rubber ring 7 are connected to the outer shell 3 by adhesive. When the negative pressure conveying device conveys silica powder, the silica powder is conveyed through the feeding pipe 2. At this time, the silica powder is dispersed by the diversion component 4, so that the silica powder passes evenly through the coarse filter component 5 and the fine filter component 6. The coarse filter component 5 and the fine filter component 6 achieve two filtrations, which improves the filtration effect. When the coarse filter component 5 and the fine filter component 6 are working, the vibrating motor 9 drives the filter screen plate 8 to vibrate. The rubber ring 7 can flexibly support the filter screen plate 8, improve the freedom of the filter screen plate 8. The vibration can effectively prevent the filter screen plate 8 from clogging. The wiring harness 10 connects the vibrating motor 9 and the control system of the negative pressure conveying device. When the negative pressure conveying device is started, the vibrating motor 9 is started synchronously. A flexible metal sleeve 12 is fitted on the outer surface of the wire harness 10. The flexible metal sleeve 12 penetrates the outer shell 3 and can protect the wire harness 10. The diversion assembly 4 consists of a diversion cone 13 and several connecting plates 14. The diversion cone 13 is located at the center inside the outer shell 3. The connecting plates 14 are welded between the diversion cone 13 and the outer shell 3. When the silica powder is conveyed, it is diffused and diverted through the diversion cone 13, so that the silica powder passes through the filter screen plate 8 evenly, avoiding the silica powder from being too concentrated and affecting the filtration efficiency. The outer shell 3 is composed of an upper shell 15 and a lower shell 16. A flange ring 17 is welded to the bottom of the outer surface of the upper shell 15, and a flange ring 2 18 is welded to the top of the outer surface of the lower shell 16. The flange ring 17 and the flange ring 2 18 are connected by several bolts, which can realize separate assembly and enable the coarse filter assembly 5 and the fine filter assembly 6 to be inspected and maintained later. The feed pipe 2 is equipped with a discharge pipe 19 located at the bottom of the filter device body 1. The discharge pipe 19 is equipped with a valve 20. After the conveying is completed, opening the valve 20 allows impurities to be discharged through the discharge pipe 19.

[0015] In operation, by setting up coarse and fine filtration components consisting of rubber rings, filter screens, vibration motors, and wiring harnesses, silica gel powder can be filtered from both sides, effectively removing impurities. Vibration effectively prevents the filter screens from clogging, thereby improving filtration efficiency. A flexible metal sleeve protects the wiring harness. A flow-dividing component consisting of a flow-dividing cone and several connecting plates disperses the silica gel powder, allowing it to pass evenly through the filter screens. A separate assembly consisting of an upper and lower shell, along with flange rings one and two, enables modular assembly, facilitating maintenance and repair. A discharge pipe and valves allow for the periodic discharge of filtered impurities.
