Description

Technical Field

[0001] This utility model belongs to the field of filtration technology, and in particular relates to a ton bag clamping device for a filter machine. Background Technology

[0002] A filter is a device that filters materials using a built-in filter element. Filters can be used in various industries such as chemical, petroleum, pharmaceutical, light industry, food, mineral processing, coal, and water treatment. Different applications have different requirements for filters. However, regardless of the type of filter, it is usually equipped with a slag discharge port for discharging the filtered residue. Currently, ton bags are placed directly below the slag discharge port to collect the residue, leading to the exposure of gas and dust during the discharge process. This not only negatively impacts the environment and is detrimental to environmental protection, but also easily causes workshop pollution and harms personnel health. Utility Model Content

[0003] In view of the defects of the prior art, the purpose of this utility model is to propose a ton bag clamp for a filter machine, which can ensure that the environment is not polluted during the slag discharge process of the filter machine.

[0004] The objective of this utility model will be achieved through the following technical solution:

[0005] A ton bag clamping device for a filter includes a detachable cylinder connected to the bottom of the filter's discharge port. A cylinder is connected to one side of the cylinder, and a ton bag connecting ring is connected to the cylinder shaft. The ton bag connecting ring is positioned below the cylinder, and an air bladder is provided around the inner side of the ton bag connecting ring. When the cylinder operates, it drives the ton bag connecting ring to move up and down along the axial direction of the cylinder. When the air bladder operates, it expands or contracts around the center of the ton bag connecting ring.

[0006] Preferably, a locking rod is connected to the cylinder, the middle part of the locking rod is connected to the cylinder pivot, and the locking rod can rotate around the pivot.

[0007] Preferably, the inner diameter of the ton bag connecting ring is larger than the outer diameter of the cylinder.

[0008] Preferably, in any of the above-described filter press ton bag clamps, a gas filtration assembly is connected to one side of the cylinder.

[0009] Preferably, the gas filtration assembly includes a housing connected to one side of the cylinder, a filter element is disposed inside the housing, a vacuum extraction port is provided at the upper end of the housing, and a backflush port is provided on one side of the vacuum extraction port.

[0010] The outstanding effect of this utility model is that it can effectively isolate the filter residue from the outside world when it is discharged, and at the same time extract irritating gases, which is beneficial to environmental protection.

[0011] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Attached Figure Description

[0019] This utility model discloses a ton bag clamping device for a filter press, combined with... Figure 1-7 As shown, the clamping device is detachably connected at the slag discharge port 3 of the filter, and includes a hollow cylinder 41 and a ton bag connecting ring 44 located below the cylinder 41. One side of the ton bag connecting ring 44 is connected to a cylinder 43 located on one side of the cylinder 41. When the cylinder 43 operates, it drives the ton bag connecting ring 44 to move up and down along the axial direction of the cylinder 41 via the cylinder shaft. In this embodiment, the cylinder 41 is connected to the filter via a connecting flange 42 at the top.

[0020] Specifically, a cylinder 43 is connected to one side of the cylinder 41 via a connecting plate. The cylinder shaft of the cylinder 43 is arranged downward along the axial direction of the cylinder and is connected to the ton bag connecting ring 44. The inner diameter of the ton bag connecting ring 44 is larger than the outer diameter of the cylinder 41.

[0021] The ton bag connecting ring 44 includes a connecting outer ring 441 and an airbag ring 442 disposed inside the connecting outer ring 441. When the airbag ring 442 is in operation, it will expand or contract in the radial direction of the connecting outer ring 441. In use, the upper opening of the ton bag is first placed inside the ton bag connecting ring 44, and then connected to the ton bag connecting ring via a connector or similar means. The connector can be wire or rope, and is not limited thereto.

[0022] When cylinder 43 operates, it drives the ton bag connecting ring 44 to rise via the cylinder shaft. At this time, the ton bag will rise along with the connecting ring 44 until it surrounds the cylinder body 41, and the opening of the ton bag will also cover the cylinder body 41. The airbag ring 442 then inflates, tightly wrapping the ton bag around the cylinder body 41. The filter begins to discharge slag, which falls into the ton bag, preventing dust dispersion and making it more environmentally friendly. After slag discharge, the airbag ring 442 retracts, and cylinder 43 drives the ton bag downwards, detaching it from the cylinder body 41.

[0023] At this point, the operator can disconnect the ton bag from the ton bag connecting ring 44. As another embodiment, to prevent accidental operation of the cylinder 43 during operation, a locking rod 45 is connected to the side of the cylinder 43. The middle part of the locking rod 45 is connected to the cylinder pivot, and the locking rod 45 can rotate around the pivot. When the locking rod 45 is in a vertical position, its bottom will abut against the ton bag connecting ring 44, thus preventing accidental upward movement of the cylinder shaft and further ensuring the operator's safety.

[0024] This utility model also discloses a ton bag clamping device for a filter machine based on any of the above-described embodiments, wherein a gas filter assembly 5 is connected to one side of the cylinder 41. The gas filter assembly 5 can filter and remove some odors during slag discharge, further ensuring the safety of personnel and the environment.

[0025] The gas filtration assembly is arranged at an angle to the cylinder 41, and includes a housing 51 connected to one side of the cylinder 41 and communicating with the cylinder. A filter element 52 is disposed inside the housing 51. A vacuum extraction port 53 is provided at the upper end of the housing 51, and a backflush port 54 is provided on one side of the vacuum extraction port 53. To avoid odors after slag discharge, a vacuum extraction port 53 can be used to remove odors. After the gas filtration assembly 5 has been used for a period of time, nitrogen can be used for backflush through the backflush port 54 to clean the filter element inside the assembly.

[0026] It should be noted that the filter described in this utility model is of a conventional form, including a filter body 1, and conventional components such as a filter element group 2 are provided inside the filter body, which will not be described in detail here.
