Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a capsule filter for chemical filtration. Background Technology

[0002] In the field of chemical filtration, capsule filters are widely used in the purification of various liquids due to their high filtration efficiency and compact structural design. Currently, most commercially available capsule filters typically use threaded connections to assemble and fix the shell to other components. This connection method, to a certain extent, ensures the filter's sealing and structural stability.

[0003] However, in actual use, when the filter element inside the filter needs to be replaced or maintained, the operator must first rotate the housing to detach it from the connecting parts. But since the housing is usually connected to pipes for conveying the liquid to be filtered or the filtered liquid, these pipes are prone to tangling during the rotation of the housing, which not only affects the smooth operation but may also damage the pipes. Therefore, to avoid pipe tangling, the operator has to disconnect the pipes connected to the housing one by one, replace the filter element, and then reconnect the pipes. This undoubtedly increases the number of steps, making the filter element replacement process cumbersome, reducing maintenance efficiency, and causing many inconveniences in actual production. In view of this, this utility model proposes a capsule filter for chemical filtration. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that existing capsule filters use threaded connections, requiring the shell to be rotated when replacing the filter element, and the pipes on the shell are easily tangled, so the pipes need to be unplugged first, resulting in cumbersome operation and low efficiency. This invention proposes a capsule filter for chemical filtration.

[0005] The technical solution of this utility model is as follows: a capsule filter for chemical filtration, comprising a first housing, a second housing, and a filter element disposed between the first housing and the second housing, further comprising: a positioning mechanism disposed inside the first housing and the second housing, the positioning mechanism preventing relative rotation between the first housing and the second housing; and a sealing assembly located at the connection between the first housing and the second housing, the sealing assembly being used to connect the first housing and the second housing and achieve a seal.

[0006] Optionally, the positioning mechanism includes multiple sets of positioning plates fixedly connected to the inner side of the second housing. The multiple sets of positioning plates are arranged in a circular array. Positioning frames are slidably connected to the multiple sets of positioning plates. The positioning frames are arranged in a "U" shape. The multiple sets of positioning frames are all fixedly connected to the inner wall of the first housing.

[0007] Optionally, the sealing assembly includes a fixed cylinder fixedly connected to the outside of the second housing, a threaded cylinder threadedly connected to the outside of the fixed cylinder, a pressure cylinder fixedly connected to the outside of the threaded cylinder, the pressure cylinder having an L-shaped cross-section, a synchronizing ring provided on the inner side of the pressure cylinder, and the synchronizing ring fixedly connected to the outer ring of the first housing.

[0008] Optionally, a rubber ring is installed on the side of the second housing near the first housing.

[0009] Optionally, the outer ring of the pressure cylinder has multiple sets of grooves, which are distributed in a ring array.

[0010] Optionally, a locking mechanism may also be provided on the outside of the threaded cylinder, the locking mechanism being used to lock the position of the threaded cylinder.

[0011] Optionally, the locking mechanism includes a deformation slot on the side of the threaded cylinder, the deformation slot being Z-shaped, and a fixing block being fixedly connected to the outer ring of the threaded cylinder, the fixing block being located in the middle of the deformation slot.

[0012] Optionally, the fixing block has a tapered threaded hole, and a screw is threaded into the tapered threaded hole. The fixing block also has a separation seam corresponding to the deformation seam.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This utility model, through the cooperation of the positioning plate and the positioning frame in the positioning mechanism, ensures that the first housing and the second housing will not rotate relative to each other during separation or assembly, effectively avoiding the problem of the pipes connected to the housing getting tangled due to rotation. At the same time, the sealing assembly adopts a linkage structure of threaded cylinder, pressure cylinder and synchronous ring, so that the disassembly and assembly of the housing can be completed without removing the pipes, greatly reducing the operation steps and significantly improving the convenience of filter element replacement and maintenance efficiency.

[0015] Furthermore, the sealing assembly achieves a seal by compressing the rubber ring when the first and second housings are joined, and the positioning plate limits the rubber ring to prevent it from shifting position, ensuring a reliable sealing effect. The locking mechanism compresses the deformation joint with screws, making the threaded cylinder and the fixed cylinder tightly engaged, avoiding accidental loosening of the threaded connection during long-term use, and further ensuring the high sealing performance and structural stability of the filter during operation.

[0016] In summary, this invention allows for filter replacement without disconnecting the pipe, avoiding pipe tangling, simplifying the operation process, and improving maintenance efficiency. Attached Figure Description

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the present invention proposes a chemical filtration capsule filter, which includes a first housing 1, a second housing 2, and a filter element 3 disposed between the first housing 1 and the second housing 2. Both the first housing 1 and the second housing 2 are provided with connecting pipes on the side away from each other for connecting the input or output liquid. The above are all prior art and will not be described in detail here.

[0032] For further details, please refer to Figure 4 The filter further includes a positioning mechanism 4 disposed inside the first housing 1 and the second housing 2. The positioning mechanism 4 prevents relative rotation between the first housing 1 and the second housing 2. The positioning mechanism 4 includes multiple sets of positioning plates 41 fixedly connected to the inner side of the second housing 2. The multiple sets of positioning plates 41 are arranged in a circular array, and positioning frames 42 are slidably connected to each of the multiple sets of positioning plates 41. The positioning frames 42 are arranged in a "U" shape, and the multiple sets of positioning frames 42 are all fixedly connected to the inner wall of the first housing 1. With the setting of the positioning mechanism 4, when the first housing 1 is close to the second housing 2, the positioning frames 42 slide on the positioning plates 41. Through their guiding effect, relative rotation between the first housing 1 and the second housing 2 is prevented, thereby preventing the pipes connected to the first housing 1 and the second housing 2 from getting tangled.

[0033] Furthermore, such as Figure 3 and Figure 4As shown, the filter also includes a sealing assembly 5 located at the connection between the first housing 1 and the second housing 2. The sealing assembly 5 connects the first housing 1 and the second housing 2 and achieves a seal. The sealing assembly 5 includes a fixed cylinder 51 fixedly connected to the outside of the second housing 2, and the position of the fixed cylinder 51 is fixed. A threaded cylinder 52 is threadedly connected to the outside of the fixed cylinder 51, and the threaded cylinder 52 moves along its own length direction when rotating. A pressure cylinder 53 is fixedly connected to the outside of the threaded cylinder 52, and the pressure cylinder 53 moves synchronously with the threaded cylinder 52. The outer ring of the pressure cylinder 53 has multiple sets of grooves, which are arranged in a ring array to facilitate the rotation of the pressure cylinder 53. The pressure cylinder 53 has an L-shaped cross-section, and a synchronizing ring 54 is provided on the inner side of the pressure cylinder 53. The synchronizing ring 54 is fixedly connected to the outer ring of the first housing 1. When the threaded cylinder 52 moves away from the first housing 1, it drives the synchronizing ring 54 to move closer to the second housing 2 through the pressure cylinder 53, thereby driving the first housing 1 to move closer to the second housing 2, realizing the connection between the first housing 1 and the second housing 2. A rubber ring 55 is installed on the side of the second housing 2 near the first housing 1. The first housing 1 presses against the rubber ring 55 when it is close to the second housing 2 to achieve a seal. At the same time, multiple sets of positioning plates 41 limit the position of the rubber ring 55 to prevent it from shifting.

[0034] Specifically, the filter also includes a locking mechanism 6 located on the outside of the threaded cylinder 52, which locks the position of the threaded cylinder 52. The locking mechanism 6 includes a deformation slot 61 on the side of the threaded cylinder 52, which is Z-shaped. A fixing block 62 is fixedly connected to the outer ring of the threaded cylinder 52, located in the middle of the deformation slot 61. A tapered threaded hole 63 is provided in the fixing block 62, and a screw 64 is threaded into the tapered threaded hole 63. A separation slot 65 corresponding to the deformation slot 61 is provided on the fixing block 62. After the screw 64 is threaded into the tapered threaded hole 63, the fixing block 62 is separated from the separation slot 65, and at the same time, the deformation slot 61 on the threaded cylinder 52 is deformed, causing the internal thread of the threaded cylinder 52 to press against the external thread of the fixing cylinder 51, thereby preventing the threaded cylinder 52 from loosening accidentally and ensuring the high sealing performance between the first housing 1 and the second housing 2.

[0035] In this embodiment, when the first housing 1 is connected to the second housing 2, the positioning frame 42 on the inner wall of the first housing 1 slides along the positioning plate 41 on the inner side of the second housing 2. Since multiple sets of positioning plates 41 are arranged in a ring array and the positioning frame 42 is in the shape of a "U", the cooperation between the two effectively prevents the first housing 1 and the second housing 2 from rotating relative to each other, thus avoiding the entanglement of the pipes connected to them. Since the fixed cylinder 51 is fixed to the outside of the second housing 2 and the threaded cylinder 52 is threadedly connected to the fixed cylinder 51, when the threaded cylinder 52 rotates towards the first housing 1, it will drive the pressure cylinder 53 to move synchronously. The pressure cylinder 53 then pushes the synchronous ring 54 fixed on the outer ring of the first housing 1, so that the first housing 1 gradually moves closer to the second housing 2. During this process, the positioning mechanism 4 plays a guiding and anti-rotation role. When the first housing 1 and the second housing 2 get close to a certain extent, the first housing 1 squeezes the rubber ring 55 on one side of the second housing 2. The rubber ring 55 deforms, achieving a seal between the two housings. At the same time, multiple sets of positioning plates 41 limit the rubber ring 55 to prevent it from shifting in position during the squeezing process and affecting the sealing performance.

[0036] After the threaded cylinder 52 is adjusted to the appropriate position, screw 64 is screwed into the tapered threaded hole 63 of the fixing block 62. Since the fixing block 62 has a separation slot 65 corresponding to the deformation slot 61, the screwing in of screw 64 will cause the fixing block 62 to separate from the separation slot 65, thereby causing the deformation slot 61 on the threaded cylinder 52 to deform. This causes the internal thread of the threaded cylinder 52 to tightly press against the external thread of the fixing cylinder 51, thereby locking the position of the threaded cylinder 52 and preventing it from loosening accidentally during the operation of the filter, ensuring that the first housing 1 and the second housing 2 always maintain a high level of sealing.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
