Description

Technical Field

[0001] This utility model relates to the field of safe grain storage, and in particular to a special sealing device for grain warehouses. Background Technology

[0002] With the continuous development of agricultural technology, grain production is also constantly increasing. To store grain for unforeseen circumstances, most existing grain storage methods involve directly piling it up in grain silos. However, during storage, excessively high temperatures and humidity can cause grain to spoil and become damp, rendering it inedible and resulting in waste. Therefore, in the grain storage industry, airtightness is a core indicator for ensuring food security. Especially in nitrogen-controlled atmosphere storage, the nitrogen concentration inside the silo must be stably maintained above 98% to effectively control pests, sterilize, and delay grain deterioration.

[0003] Existing grain storage sealing devices include sealing grooves and hose strips. A sealing membrane is placed between the sealing groove and the strip. The sealing groove is an arc-shaped structure, and the hose strip is a hollow hose. Installing the hose strip requires specialized tools, making the operation quite difficult. The effectiveness of the hose strip in pressing the membrane is greatly affected by the material of the hose strip. If the hose ages or the hose strip softens due to heat in summer, the membrane may detach from the sealing groove and the strip. Alternatively, if the pressure roller of the specialized tool used during installation derails, it may scratch the sealing membrane, creating a leak and directly compromising the airtight environment inside the grain silo. Utility Model Content

[0004] To address the shortcomings of the existing technology, this application provides a special sealing device for grain silos with good sealing performance, which can elastically and securely fix the sealing film to achieve a closed storage environment for grain silos.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special sealing device for grain storage, comprising a sealing groove tube, wherein the sealing groove tube is provided with at least two concave trapezoidal grooves with openings smaller than the bottom, a planar elastic body is snapped into the concave trapezoidal groove, and a sealing membrane is detachably snapped between the concave trapezoidal groove and the planar elastic body.

[0006] The grain silo-specific sealing device of this invention features at least two concave trapezoidal grooves with openings smaller than the bottom on the sealing tube. A planar elastic body is fitted within each concave trapezoidal groove. This allows the sealing membrane, positioned between the concave trapezoidal groove and the planar elastic body, to adhere tightly to the sealing tube through surface contact. This ensures uniform force on the pressure strip, preventing slippage and misalignment of the sealing membrane, simplifying installation and disassembly, and preventing detachment. The absence of gaps between the sealing membrane and the concave trapezoidal grooves prevents air leakage and ensures excellent sealing. The planar spring applies uniform pressure to the sealing membrane, preventing pressure damage and rupture, thus effectively maintaining an airtight environment in the grain silo. This grain silo-specific sealing device of this invention has a simple structure, is easy to operate, and provides reliable sealing, effectively improving the efficiency and stability of grain silo moisture-proof sealing operations.

[0007] Preferably, the tops of adjacent concave trapezoidal grooves are provided with rubber gaskets. Providing rubber gaskets at the tops of adjacent concave trapezoidal grooves further improves sealing performance, preventing the sealing membrane from shifting or becoming misaligned.

[0008] Preferably, the opening of the concave trapezoidal groove is provided with an arc-shaped chamfer. The arc-shaped chamfer at the opening of the concave trapezoidal groove provides a smooth transition and prevents the sealing film from being torn.

[0009] Preferably, the planar elastic body is a planar spring, which includes multiple elastic walls with connecting parts between adjacent elastic walls. Using a planar spring ensures that the sealing membrane is stably fixed to the inner surface of the concave trapezoidal groove in a surface-to-surface contact manner, increasing the contact area between the sealing membrane and the concave trapezoidal groove and avoiding the risk of pressure damage to the sealing membrane caused by single-point contact. There are no gaps between the sealing membrane and the concave trapezoidal groove, preventing air leakage and ensuring good sealing performance. The pressure exerted on the sealing membrane by the elastic walls and connecting parts is uniform, preventing pressure damage and rupture of the sealing membrane, thus effectively ensuring the airtight environment of the grain silo.

[0010] Preferably, both the elastic wall and the connecting part are straight. Using a straight elastic wall can tightly fit the concave trapezoidal groove, and using a straight connecting part can maintain the elasticity of the elastic wall and prevent the elastic wall from failing to fit into the concave trapezoidal groove due to bending or deformation of the connecting part.

[0011] More preferably, the included angle between the elastic wall and the connecting part is 100-145°. With this range of angles, the planar spring is easy to install and easy to remove from the sealing groove.

[0012] More preferably, the length of the elastic wall is 2-5 cm. Elastic walls within this length range exhibit good elasticity.

[0013] A further preferred embodiment is a planar spring formed by coating a carbon spring steel wire substrate with an anti-corrosion coating. Planar springs manufactured using this coating treatment achieve anti-corrosion and anti-fumigation effects.

[0014] Further preferably, the diameter of the carbon spring steel wire is 1.5-2mm. Using carbon spring steel wire of this size results in low cost and good elasticity.

[0015] Preferably, the concave trapezoidal groove is formed by integral stamping of aluminum alloy or PVC. The manufacturing process using aluminum alloy or PVC is simple.

[0016] Preferably, the wall thickness of the concave trapezoidal groove is 1.5-2.5 mm. Using a concave trapezoidal groove with this wall thickness results in low cost. Attached Figure Description

[0027] An embodiment of this utility model provides a sealing device specifically for grain warehouses. Example 1:

[0028] A special sealing device for grain storage includes a sealing groove tube with two concave trapezoidal grooves 1 with openings smaller than the bottom. A planar elastic body 2 is snapped into the concave trapezoidal groove 1, and a sealing membrane 3 is detachably snapped between the concave trapezoidal groove 1 and the planar elastic body 2.

[0029] The planar elastic body 2 is a planar spring, which includes multiple elastic walls 5, with connecting parts 6 between adjacent elastic walls 5. Both the elastic walls 5 and the connecting parts 6 are straight. When the planar spring is bent, the elastic walls 5 and the connecting parts 6 will form a bending arc, which is beneficial for the installation and disassembly of the planar spring, maintaining good elasticity, and maintaining the integrity and sealing performance of the sealing membrane 3.

[0030] The sealing film 3 is a plastic film.

[0031] The top of each adjacent concave trapezoidal groove 1 is provided with a rubber pad 4, which is an arc-shaped rubber pad. Since the top ends of the adjacent concave trapezoidal groove 1 are sharp corners formed by straight lines, this can easily cut the sealing membrane 3. Adding an arc-shaped rubber pad can better transition and fit the sealing membrane 3, thereby protecting the integrity of the sealing membrane 3 and extending its service life.

[0032] The included angle between the elastic wall 5 and the connecting part 6 is 100°, 110°, 120°, 130° or 145°.

[0033] The length of the elastic wall 5 is 2cm, 3cm, 4cm or 5cm.

[0034] The opening of the concave trapezoidal groove 1 is provided with an arc-shaped chamfer 7.

[0035] Planar springs are formed by coating a carbon spring steel wire substrate with an anti-corrosion coating. The diameter of the carbon spring steel wire is 1.5mm, 1.8mm, or 2mm.

[0036] The concave trapezoidal groove 1 is formed by integral stamping of aluminum alloy or PVC.

[0037] The wall thickness of the concave trapezoidal groove 1 is 1.5mm, 1.8mm, 2.0mm, 2.3mm or 2.5mm.

[0038] The installation process of the grain silo-specific sealing device involves placing the sealing film 3 on the concave trapezoidal groove 1, placing the flat spring on the surface of the sealing film 3, and having the elastic wall 5 of the flat spring engage with the side of the groove in the concave trapezoidal groove 1. The connecting part 6 of the flat spring engages with the bottom of the groove in the concave trapezoidal groove 1, thus fixing the sealing film between the concave trapezoidal groove 1 and the flat spring, preventing it from moving. This grain silo-specific sealing device is used for wall-mounted films in grain silos or on the doors and windows of grain silos to prevent them from falling off after installation.

[0039] The disassembly process of the special sealing device for grain warehouses is as follows: press the elastic wall 5 on the side of the groove of the concave trapezoidal groove 1 with the flat spring in the direction of the opening of the concave trapezoidal groove 1, so that the elastic wall 5 bounces up and the sealing film 3 loosens. In this way, the flat spring can be taken out from the opening of the concave trapezoidal groove 1, and the disassembly is quick and simple.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
