DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1 and Figure 2 As shown, an automatic sludge silo door comprises a silo body 1, with a first silo door 2 fixedly connected to one side of the silo body 1 and a second silo door 3 hingedly connected to the other side of the silo body 1; a hydraulic cylinder 6 is rotatably connected to both sides of the silo body 1, and a door pusher 12 is rotatably connected to the movable end of the hydraulic cylinder 6. The bottom of the door pusher 12 is fixedly connected to the second silo door 3, and the side of the door pusher 12 away from the hydraulic cylinder 6 is rotatably connected to the silo body 1; a sealing gasket 17 is connected to the front and rear sides of the second silo door 3, and the outer side of the sealing gasket 17 is in frictional contact with the inner wall of the silo body 1. The design of a semi-open silo door effectively reduces the height requirement when the silo door is fully opened, improves the applicability of the equipment in places with limited space, and expands its scope of application. The optimized sealing design significantly improves the sealing performance of the silo door, effectively preventing the leakage of odor from the sludge silo, improving the working environment, and protecting the environment and the health of workers.

[0029] like Figure 1 As shown, fixed seats 4 are fixedly connected to both sides of the warehouse body 1, and the fixed end of the hydraulic cylinder 6 is rotatably connected to the fixed seat 4 through a first rotating shaft 5. The fixed seat 4 provides a stable support for the fixed end of the hydraulic cylinder 6.

[0030] like Figure 1 and Figure 2As shown, the door pusher 12 is rotatably connected to the movable end of the hydraulic cylinder 6 via the third rotating shaft 13. Through the setting of the third rotating shaft 13, the door pusher 12 can be flexibly rotated under the drive of the movable end of the hydraulic cylinder 6 to realize the opening and closing of the second warehouse door 3.

[0031] like Figure 1 and Figure 2 As shown, hinge seats 7 are fixedly installed on both sides of the warehouse body 1, and support plates 10 are fixedly connected on both sides of the warehouse body 1; a second rotating shaft 9 is fixedly connected between the hinge seat 7 and the support plate 10, and a shaft sleeve 11 is rotatably connected to the outer wall of the second rotating shaft 9. The shaft sleeve 11 is fixedly connected to the side of the door pusher 12 away from the hydraulic cylinder 6, ensuring the stability of the second warehouse door 3 during the opening and closing process.

[0032] like Figure 1 and Figure 2 As shown, bolts 8 are movably inserted on both sides of the hinge seat 7, and the bottom of the bolts 8 is threadedly connected to the warehouse body 1. When the hinge seat 7 needs to be disassembled or replaced, it is only necessary to loosen the bolts 8, which is easy to operate.

[0033] like Figure 3 and Figure 4 As shown, the outer wall of the second door 3 is provided with anti-slip protrusions 20, and the outer wall of the sealing gasket 17 is in frictional contact with the anti-slip protrusions 20. The provision of the anti-slip protrusions 20 increases the friction between the sealing gasket 17 and the second door 3, and enables the sealing gasket 17 to fit more closely to the inner wall of the warehouse body 1, thereby improving the sealing performance.

[0034] like Figure 3 and Figure 4 As shown, a card slot 14 is provided on the outer wall of the second door 3, and a connecting portion 173 is provided on the sealing gasket 17. The connecting portion 173 is located inside the card slot 14. The cooperation between the card slot 14 and the connecting portion 173 facilitates the installation of the sealing gasket 17.

[0035] like Figure 3 and Figure 4 As shown, a plurality of second screw holes 16 are provided on the top of the second compartment door 3, and a first screw 18 is threadedly connected to the inner wall of the second screw hole 16. A first connecting hole 174 is provided on the top of the connecting portion 173, and the bottom of the first screw 18 passes through the second screw hole 16 and is threadedly connected to the first connecting hole 174. The connecting portion 173 of the sealing gasket 17 can be firmly fixed to the second compartment door 3 through the first screw 18, thereby enhancing the stability and reliability of the connection.

[0036] like Figure 3 and Figure 5As shown, the sealing gasket 17 includes a sealing portion 172, and the sealing portion 172 and the connecting portion 173 are an integrally formed structure. A second connecting hole 176 is provided on the outer wall of the sealing portion 172, and a first screw hole 15 is provided on the outer wall of the second compartment door 3. A second screw 19 is movably inserted into the interior of the second connecting hole 176, and the end of the second screw 19 is threadedly connected to the first screw hole 15, further strengthening the reliability of the connection between the sealing gasket 17 and the second compartment door 3.

[0037] like Figure 3 and Figure 5 As shown, the outer wall of sealing portion 172 is provided with an inclined surface 171. The provision of inclined surface 171 enables sealing gasket 17 to fit more closely against the inner wall of silo body 1 when under pressure, reducing the possibility of gaps and leakage. The outer wall of sealing portion 172 is provided with multiple protrusions 175, each of which has an arc-shaped structure. The arc-shaped structure of protrusions 175 increases the friction between sealing gasket 17 and the inner wall of silo body 1, further improving the sealing performance.

[0038] Working principle: The hydraulic cylinder 6 is in operation, and the movement of the hydraulic cylinder 6 drives the door pusher 12 to rotate around the second rotating shaft 9. At the same time, the fixed end of the hydraulic cylinder 6 rotates around the first rotating shaft 5, driving the second door 3 to rotate through the door pusher 12, so that the second door 3 is opened in a half-open position.

[0039] When the movable end of the hydraulic cylinder 6 contracts, it drives the second compartment door 3 to rotate in the opposite direction. At this time, the sealing gasket 17 of the second compartment door 3 is in contact with the inner wall of the compartment body 1. The sealing gasket 17 is squeezed by the compartment body 1 and the second compartment door 3, and can seal the gap between the compartment body 1 and the second compartment door 3. The sealing effect of the sealing gasket 17 can be further improved through the multiple protrusions 175 on the outer wall of the sealing gasket 17.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
