Description

Technical Field

[0001] This utility model relates to the field of auxiliary material tank equipment, and in particular to an auxiliary material tank with an interlocking device and the interlocking device. Background Technology

[0002] In beer production, when adding adjuncts to the mashing tank, gelatinizing tank, and boiling tank, the adjunct tanks are under high pressure. If employees open the adjunct tanks without depressurizing, the steam inside can harm them. However, employees cannot effectively check for steam pressure before opening the tanks, increasing their workload (as they need to accurately confirm the presence of steam pressure). Employee misoperation or incorrect judgment of the tank pressure (such as inaccurate pressure gauge readings) can put employees in danger.

[0003] Therefore, the problem of employees accidentally opening pressurized auxiliary material tanks and injuring themselves during the addition of auxiliary materials should be addressed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an auxiliary material tank with an interlocking device and the interlocking device itself, which can prevent employee misoperation and ensure that the auxiliary material tank is opened only after the pressure relief valve is opened to release the pressure inside, thus avoiding injury to personnel.

[0005] This utility model provides an auxiliary material container with an interlocking device, including a container body. The container lid is locked and fixed by multiple locking handles, one of which is a misoperation handle. A pressure relief valve connected to the container body is provided below the misoperation handle. An interlocking device for preventing the misoperation handle from being opened is fixed on the pressure relief handle of the pressure relief valve. The interlocking device includes a blocking mechanism. When the pressure relief handle is closed, the blocking mechanism blocks the operating space where the misoperation handle is opened. When the pressure relief handle is rotated to open, the blocking mechanism rotates with the pressure relief handle away from the operating space opened by the misoperation handle.

[0006] In one alternative embodiment, the interlocking device further includes a connector, the lower part of which is fixedly connected to the upper end face of the pressure relief handle, and the upper part of which is fixedly connected to the blocking mechanism.

[0007] In one alternative embodiment, the shielding mechanism includes a surrounding plate and a shielding plate, wherein the shielding plate is fixedly connected to the upper edge of the surrounding plate.

[0008] In one alternative embodiment, the surrounding plate is semi-circular, and the inner diameter of the surrounding plate is larger than the outer diameter of the misoperation handle, wherein the misoperation handle is a cloverleaf handle.

[0009] In one alternative embodiment, the shield extends a portion from the upper edge of the surrounding plate toward the opening of the surrounding plate.

[0010] In one alternative embodiment, the blocking area of ​​the shielding plate is greater than half of the planar area of ​​the operating space opened by the erroneous handle, and the surrounding area of ​​the surrounding plate is not less than half of the erroneous handle.

[0011] In one alternative embodiment, the connector is plate-shaped or column-shaped.

[0012] In one alternative embodiment, the can body and the can lid are connected by a hinge structure, and the misoperation handle is located on the opposite side of the hinge structure.

[0013] This utility model also provides an interlocking device for an auxiliary material tank, including a shielding mechanism and a connector. The connector is used to support the shielding mechanism. The shielding mechanism includes a surrounding plate and a shielding plate. The shielding plate is fixedly connected to the upper edge of the surrounding plate. The connector is connected to at least one of the surrounding plate or the shielding plate.

[0014] In one alternative embodiment, the surrounding plate and the shielding plate are connected by welding, and the connector is connected to the surrounding plate or the shielding plate by welding.

[0015] This invention locks the operating space of the misoperation handle of the auxiliary material tank by setting up an interlocking device. The misoperation handle can only be operated after the pressure relief handle is operated first, thereby ensuring that employees can operate the auxiliary material tank in an orderly manner and avoiding personnel injury.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model. It should be noted that the following embodiments can be combined in the absence of conflict.

[0022] Please see Figure 1 The auxiliary material container with interlocking device provided by this utility model includes a container body 7, and a container lid 9 is provided on the container body 7. The container lid 9 of the container body 7 is locked and fixed by multiple locking handles 12. Figure 1 The embodiment includes three locking handles 12 for greater stability. The rightmost locking handle 12 serves as a misoperation handle 10 to prevent accidental operation by employees. The can body 7 and the can lid 9 are connected by a hinge structure 8 (such as a hinge), with the misoperation handle 10 located on the opposite side of the hinge structure 8. If the misoperation handle 10 is not opened, the can lid 9 cannot be opened.

[0023] A pressure relief valve 6, connected to the tank 7, is located below the malfunction handle 10. The pressure relief valve 6 is connected to the tank 7 via a pipe. Opening the pressure relief valve 6 releases the steam pressure inside the tank 7, thus relieving pressure. The pressure relief valve 6 includes a pressure relief handle 4. This invention incorporates an interlocking device 5 on the pressure relief handle 4 that prevents the malfunction handle 10 from being opened. When the pressure relief handle 4 is opened, the interlocking device 5 disengages as the pressure relief handle 4 rotates. In embodiments of this invention, the interlocking device 5 displaces as the pressure relief handle 4 rotates.

[0024] like Figure 1 and Figure 2 As shown, the pressure relief valve 6 has a locking device 5 fixed to its pressure relief handle 4 to prevent the accidental opening of the handle 10. The locking device 5 includes a blocking mechanism 11. When the pressure relief handle 4 is closed, the blocking mechanism 11 blocks the operating space where the accidental handle 10 is opened, preventing employees from operating the handle 10 from above. When the pressure relief handle 4 is turned clockwise to open, the blocking mechanism 11 follows the clockwise rotation of the pressure relief handle 4, moving away from the operating space where the accidental handle 10 is opened, allowing the handle 10 to be opened normally once there is no obstruction.

[0025] In some embodiments, the pressure relief handle 4 is a butterfly valve handle. Utilizing the principle of the butterfly valve handle rotation switch, the blocking mechanism 11, which rotates with the butterfly valve switch, blocks the erroneous handle 10 when the pressure relief valve 6 is closed, and conversely, opens the erroneous handle 10 when the pressure relief valve 6 is opened.

[0026] Please continue reading. Figure 2 As shown, the interlocking device 5 also includes a connector 3, the lower part of which is fixedly connected to the upper end face of the pressure relief handle 4, and the upper part of which is fixedly connected to the blocking mechanism 11. The blocking mechanism 11 includes a surrounding plate 2 and a blocking plate 1. The surrounding plate 2 is semi-circular, and the blocking plate 1 is fixedly connected to the upper edge of the surrounding plate 2.

[0027] In some embodiments, the connector 3 is plate-shaped or column-shaped; a plate-shaped structure of the connector 3 provides better shielding. The connector 3, the surrounding plate 2, and the shielding plate 1 are connected by welding, which ensures a firm connection and better shielding effect. The connector 3 can be fixedly connected to the surrounding plate 2 or the shielding plate 1, or simultaneously to both, serving a supporting and fixing function. In other embodiments, the three components can also be fixedly connected by screws.

[0028] Please see Figure 3 As shown, the inner diameter of the surrounding plate 2 is larger than the outer diameter of the erroneous handle 10, which can better shield the erroneous handle 10 and prevent scratches to the erroneous handle 10. Figure 3 The misoperation handle 10 mentioned above is a cloverleaf handle. The cloverleaf handle requires employees to operate and rotate it from above. The shielding mechanism 11 can effectively shield the cloverleaf handle.

[0029] Furthermore, the baffle 1 extends a portion from the upper edge of the surrounding plate 2 toward the opening of the surrounding plate 2, which can better provide tension space and reduce the operating space of the handle 10 in case of accidental operation. In some embodiments, the shape of the baffle 1 can be adapted to the shape of the upper edge of the surrounding plate 2.

[0030] exist Figure 3 In this embodiment, the blocking area of ​​the shielding plate 1 is greater than half the planar area of ​​the operating space opened by the erroneous handle 10, and the enclosure range of the surrounding plate 2 is not less than half of the erroneous handle 10. Figure 3 It can be seen that the shield 1 can effectively prevent employees from operating the handle 10 by mistake.

[0031] This utility model also provides an interlocking device 5 for auxiliary material tanks, which can be referred to in the following section. Figure 2As shown, the interlocking device 5 includes a blocking mechanism 11 and a connecting member 3. The connecting member 3 supports the blocking mechanism 11. The blocking mechanism 11 includes a surrounding plate 2 and a blocking plate 1. The blocking plate 1 is fixedly connected to the upper edge of the surrounding plate 2. The connecting member 3 is connected to at least one of the surrounding plate 2 or the blocking plate 1. The surrounding plate 2 and the blocking plate 1 are connected by welding, and the connecting member 3 is connected to the surrounding plate 2 or the blocking plate 1 by welding.

[0032] This invention features a pressure relief valve on an auxiliary material addition tank. An interlocking device is connected to the pressure relief valve's handle. When the pressure relief valve is opened, the blocking mechanism of this device cancels the blocking of the locking handle of the auxiliary material tank. Conversely, when the pressure relief valve is closed, the blocking mechanism blocks the locking handle, thus achieving an interlock between the pressure relief valve and the locking handle. The auxiliary material tank cannot be opened before the pressure relief valve is opened, thereby preventing employee misoperation.
