In practice, with the second compression spring 2005, when excessive air pressure is vented, the stopper 2004 may be pulled to move downward to block the sealed reservoir 1. It can be understood that the danger of frying the cans caused by overlarge pressure in the material storage tank 1 can be effectively prevented through pressure relief.

Referring to fig. 5, the sealing mechanism 21 includes a second bearing 2101 fixedly connected to the top end of the material storage tank 1. An L-shaped plate 2102 is rotatably connected to the tip of the second bearing 2101, and a second hydraulic telescopic rod 2103 is fitted to the tip of the L-shaped plate 2102.

Referring to fig. 5, the latex plate 2106 is movably connected to the top end of the feed port 4. The latex plate 2106 forms an elastic telescopic structure with the push plate 2104 through the third compression spring 2105, and the push plate 2104 forms a lifting structure with the L-shaped plate 2102 through the second hydraulic telescopic rod 2103. In this embodiment, the L-shaped plate 2102 forms a rotating structure with the material storage tank 1 through the second bearing 2101, and the second hydraulic telescopic rod 2103 can drive the push plate 2104 to move up and down. Push plate 2104 can drive latex board 2106 and go up and down to remove, extrudes latex board 2106 at the open end of feed inlet 4, can plug up the open end of feed inlet 4 sealedly. It can be understood that the pressing force of the latex sheet 2106 against the feed port 4 can be relieved by the elastic property of the third compression spring 2105 to prevent the latex sheet 2106 or the feed port 4 from being damaged due to the pressing too hard.

The working principle is as follows:

when the device is used, granular materials are fed through the feeding hole 4, then enter the material storage tank 1 through the feeding pipe 3, so that the granular materials are stored in the material storage tank 1, the L-shaped plate 2102 is manually rotated, the L-shaped plate 2102 rotates through the second bearing 2101, the L-shaped plate 2102 drives the second hydraulic telescopic rod 2103 to move, the latex plate 2106 arranged at the lower end of the second hydraulic telescopic rod 2103 is moved to the upper end of the feeding hole 4, and then the second hydraulic telescopic rod 2103 drives the push plate 2104 to move downwards;

the push plate 2104 drives the latex plate 2106 to move downward, so that the latex plate 2106 extrudes the open end of the feed port 4 to plug and seal the open end of the feed port 4. Meanwhile, the extrusion force of the latex plate 2106 on the feed port 4 is relieved by the elastic characteristic of the third compression spring 2105, so that the latex plate 2106 or the feed port 4 is prevented from being damaged due to too-violent extrusion. Then, one end of the third conduit 17 is inserted into the air inlet tube 1901, and the sealing rubber ring 1903 is pulled manually to move the sealing rubber ring 1903 on the surface of the third conduit 17.

Slide sealing rubber ring 1903 and get into in intake pipe 1901 in order to laminate the one end at connecting plate 1902, again manual rotation hand screw bolt 1904, hand screw bolt 1904 rotates in intake pipe 1901 and removes, drives arc clamp plate 1906 and removes, makes arc clamp plate 1906 extrude the surface of sealing rubber ring 1903, will seal rubber ring 1903 extrusion and fix.

The sealing rubber ring 1903 is attached and fixed to the connecting gap between the air inlet pipe 1901 and the third conduit 17, so that the connecting gap between the air inlet pipe 1901 and the third conduit 17 is blocked and sealed, and the air leakage is prevented. In addition, the particulate material in the material storage tank 1 is pumped from the first discharge pipe 6 to the first conduit 7 by the pneumatic pump 8. The material enters the second guide pipe 12 through the pneumatic pump 8, then enters the material collecting tank 13 through the second guide pipe 12, and finally is discharged through a second discharge pipe 14 at the bottom end of the material collecting tank 13.

Meanwhile, the filter screen 16 installed on the inner wall of the material collecting tank 13 filters the particulate materials in the air, and the filtered air enters the material storage tank 1 through the third conduit 17 to form air circulation, so that the material conveying speed is increased, and the energy consumption of the pneumatic pump 8 during operation is reduced. Meanwhile, drive layer board 1803 through first hydraulic telescoping rod 1802 and stretch out and draw back and move in collection material jar 13, layer board 1803 drives the cleaning brush 1805 on top and makes a round trip to scrape in filter screen 16's bottom, cleaning brush 1805 cleans its filter screen 16's bottom, in order to clear up the granule material that filter screen 16 bottom bonded, the messenger drops to collection material jar 13's bottom, thereby prevent that filter screen 16 bottom from bonding too much particulate matter and causing the jam, make gaseous unable filter screen 16 that passes through, guarantee device's normal operating.

Meanwhile, the cleaning brush 1805 is pressed to move upwards by the elastic characteristic of the first compression spring 1804, so that the cleaning brush 1805 is tightly attached to the bottom end of the filter screen 16, and the cleaning effect is improved. When the air pressure in the storage tank 1 gradually increases during operation, the sleeve 2002 is pressed by the excessive air pressure, the sleeve 2002 is pressed and moves upwards in the pressure release valve 2001, the baffle 2004 is driven to move upwards, and the sleeve 2002 is partially moved out of the pressure release valve 2001, so that different numbers of pressure release holes 2003 are exposed. The pressure relief operation is performed on the material storage tank 1 through the pressure relief hole 2003 to prevent the danger of tank explosion caused by the high pressure inside the material storage tank 1.
