Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment maintenance technology, specifically a special wrench suitable for densely arranged joints in fermentation tanks. Background Technology

[0002] Fermentation tanks are widely used in many industries such as food, pharmaceuticals, and biochemicals. Small tanks often have many non-standard threaded joints on their top covers. These joints vary in size and shape, and there are no universal wrenches available on the market. Currently, pump wrenches are mostly used when operating fermentation tank joints. However, due to the dense arrangement of joints on the fermentation tank top cover, the space between adjacent joints is very limited. Pump wrenches are large and difficult to rotate flexibly in this confined space. They often interfere with surrounding joints or other components, limiting the convenience and accuracy of operation and increasing the time and cost of maintenance.

[0003] To address this issue, we designed a special wrench suitable for densely arranged joints in fermentation tanks. Utility Model Content

[0004] The purpose of this invention is to provide a special wrench suitable for densely arranged joints in fermentation tanks, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a special wrench suitable for densely arranged joints in fermentation tanks, including a handle. A main operating head and a spare operating head are fixedly connected to both ends of the handle. The inner surfaces of the main operating head and the spare operating head are designed with non-standard geometric shapes to adapt to the thread type of the joint. The main operating head and the spare operating head are different in size and can be adapted to different joints.

[0006] Furthermore, the outer surface of the handle is integrally formed with anti-slip ridges.

[0007] Furthermore, rubber gaskets are bonded to the inner sides of the main operating head and the backup operating head.

[0008] Furthermore, the handle, main operating head, and backup operating head are all open-type designs.

[0009] Furthermore, a certain angle is formed between the outer wall of the main operating head and the outer side of the handle.

[0010] Furthermore, the handle is made of lightweight aluminum alloy, and both the main operating head and the backup operating head are made of 316 stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By fixing the main operating head and the spare operating head to both ends of the handle, the main operating head and the spare operating head are different in size, and the inner surface of both are designed with non-standard geometric shapes to adapt to the tooth shape of the connector, which can adapt to different connectors and improve the versatility of the wrench. In addition, the handle is designed to be longer. According to the lever principle, when disassembling or installing the fermenter connector, the operator can apply torque more effortlessly to complete the disassembly and installation of the connector.

[0013] 2. The handle's outer surface is integrally molded with anti-slip ridges, enhancing operational stability and safety, and reducing operational errors caused by slippage. The rubber pads bonded to the inner sides of the main and backup operating heads are soft and elastic, cushioning the impact during operation when the wrench contacts the connector, preventing scratches on the connector surface due to rigid contact, and increasing the friction between the wrench and the connector to assist torque transmission and further prevent slippage. A certain angle is formed between the outer wall of the main operating head and the outer side of the handle. When the operator turns the handle, the main operating head contacts the target connector at a suitable angle and will not collide or interfere with adjacent connectors during operation. The handle, main operating head, and backup operating head are all open-type designs, making it easy to quickly slip the wrench onto the fermenter connector and saving operation time.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a special wrench suitable for densely arranged joints in fermentation tanks, including a handle 2. The handle 2 is designed to be extended. When operating the fermentation tank joints, due to the leverage effect, the extended handle 2 allows the operator to apply torque more effortlessly. The two ends of the handle 2 are respectively fixedly connected to a main operating head 1 and a spare operating head 4. The handle 2, the main operating head 1, and the spare operating head 4 are precision machined by CNC to improve the accuracy of the wrench's dimensions. Their surfaces are electrolytically polished to increase the wrench's durability. The inner surfaces of the main operating head 1 and the spare operating head 4 are designed with non-standard geometric shapes to adapt to the joint tooth type. The main operating head 1 and the spare operating head 4 have different sizes to adapt to different joints.

[0021] In practice, first observe the size and tooth profile of the fermenter connector. When the main operating head 1 is selected, the operator holds the handle 2 and aligns the opening of the main operating head 1 with the connector on the top cover of the fermenter, so that the inner side of the main operating head 1 contacts the surface of the connector. The operator holds and rotates the handle 2. During the rotation, the non-standard geometric protrusions on the inner side of the main operating head 1 fit tightly with the connector tooth profile, effectively transmitting torque and enabling the disassembly or installation of the connector. When the spare operating head 4 is required, the same principle applies as when using the main operating head 1. Align the opening of the spare operating head 4 with the corresponding fermenter connector, then hold and rotate the handle 2. The operation of the connector is completed by the fit between the non-standard geometric shape on the inner side of the spare operating head 4 and the connector tooth profile.

[0022] See Figure 1 As shown, the outer surface of the handle 2 is integrally formed with anti-slip ridges 3, which are honeycomb-shaped and used to increase the friction between the handle 2 and the hand, reduce operational errors caused by slippage, and enhance the stability and safety of operation.

[0023] See Figure 3 The main operating head 1 and the spare operating head 4 are bonded with rubber pads 5, which are soft and have a certain degree of elasticity. When the wrench comes into contact with the connector, it can buffer the impact force during the operation, prevent the connector surface from being scratched due to rigid contact, increase the friction between the wrench and the connector, assist in torque transmission, and further prevent slippage.

[0024] See Figure 4 The handle 2, main operating head 1 and spare operating head 4 are all open-type designs, which makes it easy to quickly put the wrench on the fermenter connector and saves operation time.

[0025] See Figure 2 The outer side wall of the main operating head 1 and the outer side of the handle 2 form a certain angle. When the operator turns the handle 2, the main operating head 1 contacts the target connector at a suitable angle and will not collide or interfere with adjacent connectors during operation.

[0026] See Figure 1 The handle 2 is made of lightweight aluminum alloy, which reduces operator fatigue during long-term operation and improves work efficiency and operation accuracy. The main operating head 1 and the backup operating head 4 are both made of 316 stainless steel, which is corrosion resistant and chemical resistant, and can adapt to various corrosive media that may exist around the fermenter.

[0027] Working principle: When using, first observe the size and tooth profile of the fermenter connector. When determining to use the main operating head 1, the operator holds the handle 2 and aligns the opening of the main operating head 1 with the connector on the top cover of the fermenter, so that the rubber gasket 5 on the inner side of the main operating head 1 makes light contact with the connector surface. The rubber gasket 5 not only protects the connector surface from scratches, but also increases friction to a certain extent to prevent slippage during operation. Since the outer surface of the handle 2 is integrally formed with anti-slip ridges 3, it is convenient for the operator to grip and rotate the handle 2. During rotation, the non-standard geometric protrusions on the inner side of the main operating head 1 fit tightly with the connector tooth profile, effectively transmitting torque to achieve the disassembly or installation of the connector. Since the handle 2 is an extended design, and a certain angle is formed between the outer wall of the main operating head 1 and the outer side of the handle 2, interference with adjacent connectors is avoided during operation, allowing the wrench to adapt to the tightly arranged connectors and complete the operation smoothly.

[0028] When the spare operating head 4 is needed, the same principle applies as when using the main operating head 1. Align the opening of the spare operating head 4 with the corresponding fermenter connector, so that the rubber gasket 5 contacts the connector surface. Then, hold the handle 2, using the anti-slip ridge 3 to increase the stability of the grip, and rotate the handle 2. The non-standard geometry inside the spare operating head 4 and the connector tooth shape are matched to complete the connector operation task.
