Description

Technical Field

[0001] This utility model relates to the field of fermentation tank equipment, specifically to a sealing device for fermentation tanks. Background Technology

[0002] Livestock and poultry manure fermentation tanks mix livestock and poultry manure with biological fermentation bacteria. The activity of these microorganisms decomposes the organic matter in the waste, transforming it into organic fertilizer for the soil. After the materials are placed in the fermentation tank, it needs to be sealed to facilitate microbial fermentation. Existing sealing devices typically use simple lids, allowing air to easily enter through the gap between the lid and the main body. This can lead to surface spoilage of the food, uneven fermentation, and poor fermentation results. Utility Model Content

[0003] In view of this, the present invention provides a sealing device for a fermenter, which can be connected to the cover via a hinged seat. When the cover is in close contact with the inner wall of the fermenter, the drive motor is started. The drive motor drives the extrusion rod to push the sealing plate into the sealing cavity, thereby sealing the gap between the cover and the inner wall of the fermenter and preventing gas from entering the interior of the fermenter through the gap between the cover and the inner wall of the fermenter.

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing device for a fermentation tank, including a fermentation tank for fermenting materials. The fermentation tank has a feed inlet at the top for pouring materials into the fermentation tank. A cover is provided at the feed inlet and fits against the inner wall of the feed inlet to seal the feed inlet. A sealing plate is provided inside the cover for sealing the cover around its perimeter. A sealing cavity is provided inside the fermentation tank for cooperating with the cover. The sealing cavity cooperates with the sealing plate to prevent air from entering the fermentation tank through the gap where the sealing plate fits against the inner wall of the fermentation tank. The sealing plate is movably disposed within the sealing cavity.

[0005] The cap has grooves around its perimeter to accommodate the sealing plate, allowing it to fit snugly against the inner wall of the fermenter and preventing the sealing plate from obstructing the opening and closing of the cap. The sealing plate is movably positioned within the grooves. A through hole is located on one side of the groove to limit the movement of the connecting rod. The connecting rod, which connects to the sealing plate, is located within the through hole and is used to connect the sealing plate and the baffle.

[0006] A square hole is provided at the center of the base surface of the cap. The square hole is used to rotate the extrusion rod. A baffle is provided inside the square hole and connected to the other end of the connecting rod. The baffle is used to drive the connecting rod to move. The baffle increases the contact area with the connecting rod, so that the extrusion rod can drive the connecting rod to move better. A return spring is sleeved on the side of the connecting rod near the baffle. The return spring is used to pull the sealing plate out of the sealing cavity to prevent the cap from being unable to be opened.

[0007] A pressing rod is provided inside the square hole. The pressing rod is used to press the baffle, causing the baffle to move the connecting rod to one side of the sealing cavity and push the sealing plate to the middle position of the sealing strip inside the sealing cavity. A drive motor is connected above the pressing rod. The drive motor is used to drive the pressing rod to rotate. A bracket is connected to the cover. The bracket is used to connect the cover and support the drive motor. The drive motor is connected and set on the bracket.

[0008] The sealed cavity is symmetrically equipped with sealing strips at the top and bottom. The sealing strips are used to prevent air from entering the fermenter, and the sealing plate is movably arranged between the sealing strips.

[0009] The fermenter and the cap are connected by a hinged seat that facilitates the cap's flipping, and the sealing plate is arc-shaped.

[0010] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0011] 1. Pour the material to be fermented into the fermentation tank through the feed inlet. Flip the cap using the hinged seat to seal the feed inlet. Then start the drive motor. The output of the drive motor drives the extrusion rod to rotate. The initial position of the extrusion rod is located at the diagonal of the square hole. The extrusion rod extrudes the baffle. After extrusion, the baffle moves the connecting rod. The connecting rod moves the sealing plate to one side of the sealing cavity, so that the sealing plate is located in the middle of the sealing strip. This blocks the gap between the cap and the inner wall of the fermentation tank, preventing air from entering the fermentation tank through the gap where the cap and the inner wall of the fermentation tank meet.

[0012] 2. The sealing plate can improve the sealing performance of the cap and reduce the formation of gaps. When the extrusion rod moves away from the baffle, the return spring pushes the baffle in the opposite direction. The baffle drives the connecting rod, causing the sealing plate to be pulled out of the sealing cavity, thus opening the cap.

[0013] 3. A sealing cavity is set on the inner wall of the fermenter, and a sealing strip is installed in the sealing cavity. The sealing strip wraps and seals the sealing plate to prevent gas from entering the fermenter through the gap between the sealing plate and the sealing cavity. Attached Figure Description

[0021] like Figure 1-4 As shown:

[0022] This embodiment provides a sealing device for a fermentation tank, including a fermentation tank 100. The fermentation tank 100 is used to ferment materials. A feed inlet 101 is provided at the top of the fermentation tank 100 for pouring materials into the fermentation tank 100. A cover 102 is provided at the feed inlet 101 and is fitted to the inner wall of the feed inlet 101 to seal the feed inlet 101. A sealing plate 103 is provided inside the cover 102 to seal the surrounding area of ​​the cover 102. A sealing cavity 104 is provided inside the fermentation tank 104 to cooperate with the cover 102. The sealing cavity 104 is used to cooperate with the sealing plate 103 to prevent air from entering the fermentation tank 100 through the gap where the sealing plate 103 is fitted to the inner wall of the fermentation tank. The sealing plate 103 is movably disposed in the sealing cavity 104.

[0023] The cover 102 has a groove 105 around its perimeter. The groove 105 is used to place the sealing plate 103, so that the cover 102 can fit against the inner wall of the fermentation tank 100. This prevents the sealing plate 103 from obstructing the opening and closing of the cover 102. The sealing plate 103 is movably disposed in the groove 105. A through hole 106 is provided on one side of the groove 105. The through hole 106 is used to limit the connecting rod 107. The connecting rod 107, which is connected to the sealing plate 103, is disposed in the through hole 106. One end of the connecting rod 107 is fixedly connected to the sealing plate 103, and the other end of the connecting rod 107 is fixedly connected to the baffle 109. The connecting rod 107 is used to connect the sealing plate 103 and the baffle 109.

[0024] A square hole 108 is provided at the center of the base surface of the cover 102. The square hole 108 is used to rotate the extrusion rod 111. A baffle 109 is provided inside the square hole 108 and connected to the other end of the connecting rod 107. The baffle 109 is used to drive the connecting rod 107 to move. The baffle 109 increases the contact area with the connecting rod 107, so that the extrusion rod 111 can drive the connecting rod 107 to move better. A return spring 110 is sleeved on the side of the connecting rod 107 near the baffle 109. The return spring 110 is used to pull the sealing plate 103 out of the sealing cavity 104 to prevent the cover 102 from not being able to open.

[0025] A pressing rod 111 is provided inside the square hole 108. A roller can be set at one end of the pressing rod 111 near the baffle 109. The pressing rod 111 can reduce the friction when pressing the baffle 109. The pressing rod 111 is used to press the baffle 109, causing the baffle 109 to drive the connecting rod 107 to move towards the sealing cavity 104 and push the sealing plate 103 to the middle position of the sealing strip 114 in the sealing cavity 104. A drive motor 112 is connected above the pressing rod 111. The drive motor 112 is used to drive the pressing rod 111 to rotate. A bracket 113 is connected to the cover 102. The bracket 113 is used to connect the cover 102 and support the drive motor 112. The drive motor 112 is connected to the bracket 113.

[0026] A sealing strip 114 is symmetrically arranged in the upper and lower parts of the sealed cavity 104. The sealing strip 114 is adhered to the upper and lower base surfaces in the sealed cavity 104. The sealing strip 114 is used to prevent air from entering the fermenter 100. The sealing plate 103 is movably arranged between the sealing strips 114.

[0027] A hinge seat 115 is provided between the fermenter 100 and the cover 102 to facilitate the flipping of the cover 102. One end of the hinge seat 115 is connected to the fermenter 100 by bolts, and the other end of the hinge seat 115 is connected to the cover 102 by bolts. The sealing plate 103 is arc-shaped.

[0028] Working principle: During use, the material to be fermented is poured into the fermentation tank 100 through the feed inlet 101. The cap 102 is flipped by the hinge seat 115, sealing the feed inlet 101. Then, the drive motor 112 is started, and the output end of the drive motor 112 drives the extrusion rod 111 to rotate. The initial position of the extrusion rod 111 is located at the diagonal of the square hole 108. The extrusion rod 111 extrudes the baffle 109. After extrusion, the baffle 109 drives the connecting rod 107, and the connecting rod 107 drives the sealing plate 103 to move towards the sealing cavity 104. The sealing plate 103 is positioned in the middle of the sealing strip 114, blocking the gap between the cover 102 and the inner wall of the fermentation tank 100. This prevents air from entering the fermentation tank 100 through the gap where the cover 102 and the inner wall of the fermentation tank 100 meet. The sealing plate 103 improves the sealing performance of the cover 102 and reduces the formation of gaps. When the squeezing rod 111 moves away from the baffle 109, the return spring 110 pushes the baffle 109 in the opposite direction. The baffle 109 drives the connecting rod 107, causing the sealing plate 103 to be pulled out of the sealing cavity 104, thus opening the cover 102.
