Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter technology, specifically a filter head clamping assembly tool for a rotary filter. Background Technology
[0002] Rotary filters are common industrial filtration devices widely used in petrochemical, pharmaceutical, and food processing industries. Their core function is to achieve efficient solid-liquid separation or media purification through the rotation of the filter cartridge. In the structure of a rotary filter, the assembly quality of the filter cartridge and filter head directly affects the sealing performance and service life of the equipment. In traditional assembly, the filter cartridge and filter head are usually connected by threaded tightening. However, due to the heavy weight of the filter cartridge and the high requirement for coaxiality, precise alignment of the two must be ensured during assembly; otherwise, it can easily lead to seal failure or component wear.
[0003] Currently, most filter cartridges are assembled by manually tightening the filter cover. Operators need to manually screw the filter head onto the filter cartridge, which makes it difficult to guarantee assembly accuracy. Problems such as misaligned threads and uneven pressure on the sealing ring often occur, which in turn affects the overall sealing performance of the filter. In addition, the consistency of manual operation is poor, which may cause some products to leak prematurely due to improper assembly. Utility Model Content
[0004] The purpose of this invention is to provide a filter head clamping assembly tool for a rotary filter, so as to solve at least one aspect of the problems and defects mentioned in the background art.
[0005] A clamping and assembly fixture for a rotary filter head is provided, including an installation platform, a bottom limiting mechanism slidably connected to the installation platform, a lifting frame provided on the installation platform, a rotating mechanism rotatably connected to the upper part of the lifting frame, and filter head limiting mechanisms provided on both sides of the rotating mechanism, the filter head limiting mechanisms being used to clamp and limit the filter head.
[0006] Furthermore, the bottom limiting mechanism includes a sliding platform slidably connected above the mounting platform. A limiting sleeve is detachably connected to the center of the sliding platform. During operation, the operator can push the sliding platform onto the mounting platform to adjust the position of the limiting sleeve according to the size of the filter cartridge or assembly requirements, aligning the center of the limiting sleeve with the axis of the rotating mechanism. After adjustment, the sliding platform is locked in place by tightening screws for secure positioning. It can then be removed after installation.
[0007] Furthermore, the limiting sleeve is provided with a positioning groove, which matches the shape and size of the bottom of the filter cylinder. It is used to lock and limit the filter cylinder. During the process of the rotating mechanism driving the filter head to screw in, the filter cylinder can remain stationary, thereby ensuring that the filter head is screwed in smoothly and achieves sealing and pressing.
[0008] Furthermore, the limiting sleeve is detachably connected to the sliding platform. Different models of rotary filters correspond to different sizes of filter cartridges, so the size of the limiting sleeve is also different. With the detachable structure, the limiting sleeve only needs to be replaced on the sliding platform.
[0009] Furthermore, the rotating mechanism includes a rotating connecting rod, which is rotatably connected to the center of the lifting frame. A rotating mounting plate is fixedly connected to the rotating connecting rod, and a filter head limiting mechanism is fixedly connected to the rotating mounting plate. By rotating the rotating connecting rod, the operator can drive the rotating mounting plate and the filter head limiting mechanism on it to rotate synchronously, thereby enabling the filter head to be screwed into the filter cartridge below. This structure can effectively avoid assembly deviations caused by manual tightening and improve assembly efficiency and coaxial accuracy.
[0010] Furthermore, the rotating connecting rod is provided with an internal hexagonal hole. The operator can insert an internal hexagonal wrench into the internal hexagonal hole of the rotating connecting rod and rotate the wrench to make the rotating connecting rod drive the filter head clamped in the filter head limiting mechanism to rotate, thereby driving the filter head to tighten or loosen. This facilitates operation, effectively improves the tightening accuracy and efficiency during assembly, and avoids axial deviation and overload damage caused by traditional hand-operated tightening.
[0011] Furthermore, the filter head limiting mechanism includes a connecting plate, which is fixedly connected to a rotating mounting plate. A limiting screw is provided on the rotating mounting plate, and a positioning pin is fixedly connected to the limiting screw. The positioning pin is engaged in the locking holes on both sides of the filter head. This ensures that the filter head does not slide axially or wobble radially during rotation, or fall off. After assembly, simply loosen the limiting screw to remove the positioning pin and release the filter head.
[0012] Furthermore, the positioning pin is provided with a tapered guide. During the installation process, as the positioning pin is pushed, the tapered guide can guide it to quickly align and insert into the locking hole of the filter head. Even if there is a slight hole position deviation, it can be automatically corrected through the guide surface, thereby improving assembly efficiency and positioning accuracy.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] The filter cartridge is placed on the bottom limiting mechanism for accurate positioning. The filter head is clamped by the filter head limiting mechanism, and the lifting frame is adjusted to align the filter head with the filter cartridge. The rotating mechanism is then activated, causing the filter head to rotate around the central axis, achieving automatic screwing between the filter head and the filter cartridge. After screwing, the limiting mechanism is released, and the operator adjusts the sliding platform to move the assembled rotary filter out of the lower part of the rotating mechanism. The assembled rotary filter is then removed from inside the limiting sleeve. Compared to the traditional method of manually tightening the filter cover, where the filter head requires manual screwing with the filter cartridge, this method improves assembly efficiency, automatically limits alignment, effectively avoids problems such as misaligned threads and uneven pressure on the sealing ring, ensures assembly quality, and improves product consistency.

[0022] However, there may be instances where unnecessary detailed descriptions are omitted.

Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.
[0023] Please see Figure 1-3 As shown in the embodiment of this utility model, a filter head clamping assembly fixture for a rotary filter includes an installation platform 1. A bottom limiting mechanism 2 is slidably connected to the installation platform 1. A lifting frame 3 is provided on the installation platform 1. (The lifting frame 3 consists of a support column and a lifting slide. The lifting slide moves up and down on the column, thereby driving the upper rotating mechanism 4 to rise and fall accordingly. The operator can adjust the height of the entire lifting frame 3 according to the height of the filter cylinder 100 or the assembly position of the filter head to achieve axis alignment. The lifting frame 3 is then locked in a sliding position to ensure rigidity and accuracy during the assembly process.) A rotating mechanism 4 is rotatably connected to the upper part of the lifting frame 3. Filter head limiting mechanisms 5 are provided on both sides of the rotating mechanism 4. The filter head limiting mechanisms 5 are used to clamp and limit the filter head 6.
[0024] The filter cartridge 100 is placed on the bottom limiting mechanism 2 to position it. The filter head 6 is clamped by the filter head limiting mechanism 5. The sliding platform 21 slides and adjusts its position on the installation platform 1 until the filter cartridge 100 is below the filter head 6. The height of the lifting frame 3 is adjusted so that the filter head 6 clamped on the filter head limiting mechanism 5 is aligned with the filter cartridge 100. The rotating mechanism 4 is started to drive the filter head 6 to rotate around the central axis, achieving automatic engagement with the filter cartridge 100. After engagement, the filter head limiting mechanism 5 is released. The operator adjusts the sliding platform 21 again to move the assembled rotary filter out of the lower part of the rotating mechanism 4. The assembled rotary filter is then removed from the bottom limiting mechanism 2. Compared with the traditional method of manually tightening the filter cover, the filter head needs to be manually threaded onto the filter cartridge 100, which improves assembly efficiency, enables automatic positioning and alignment, effectively avoids problems such as misaligned threads and uneven pressure on the sealing ring, ensures assembly quality, and improves product consistency.
[0025] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The bottom limiting mechanism 2 includes a sliding platform 21. In specific implementation, the sliding platform 21 is slidably connected above the installation platform 1. A limiting sleeve 22 is set on the center of the sliding platform 21. (The installation platform 1 has slide rails on both sides, and sliders are set on the slide rails. The sliding platform 21 is fixedly connected to the sliders. After the sliders slide into place, the sliders can be fixed by passing the locking screws through the limiting holes on the sliders and the mounting holes on the slide rails, so as to adjust the specific position of the entire sliding platform 21, which is convenient for operators to install the filter head 6.) The limiting sleeve 22 is fixedly installed in the center of the sliding platform 21. The limiting sleeve 22 is a hollow cylindrical structure. Its inner diameter is adapted to the outer diameter of the assembled filter cartridge 100. When the filter cartridge 100 is placed, it can be inserted into the limiting sleeve 22, with the bottom fitting together to prevent position displacement during the screwing process. During operation, the operator can push the sliding platform 21 to slide on the installation platform 1 according to the size of the filter cartridge 100 or the assembly requirements, and adjust the position of the limiting sleeve 22 so that the center of the limiting sleeve 22 is aligned with the axis of the rotating mechanism 4. After adjustment, the sliding platform 21 is locked in place by tightening screws to achieve a stable limit. It can be removed after installation.
[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The limiting sleeve 22 is provided with a positioning groove 221, which matches the shape and size of the bottom of the filter cylinder 100. It is used to lock and limit the filter cylinder 100, realize the directional positioning and anti-rotation restriction of the filter cylinder 100. During the process of the rotating mechanism 4 driving the filter head to screw in, the filter cylinder 100 can remain stationary, thereby ensuring that the filter head 6 can be screwed in smoothly and achieve sealing and pressing.
[0027] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The limiting sleeve 22 is detachably connected to the sliding platform 21. Different models of rotary filters correspond to different sizes of filter cartridges 100, so the size of the limiting sleeve 22 is also different. With the detachable structure, the limiting sleeve 22 can be replaced simply by replacing it on the sliding platform 21.
[0028] Further, please refer to Figure 1 , Figure 2 and Figure 3 The rotating mechanism 4 includes a rotating connecting rod 41, which is rotatably connected to the upper center of the lifting frame 3. A rotating mounting plate 42 is fixedly connected to the rotating connecting rod 41, and a filter head limiting mechanism 5 is fixedly connected to the rotating mounting plate 42 for clamping the filter head 6 during rotation. In actual operation, the operator can rotate the rotating connecting rod 41 to drive the rotating mounting plate 42 and the filter head limiting mechanism 5 on it to rotate synchronously, thereby enabling the filter head 6 to be screwed into the filter cylinder 100 below. This structure can effectively avoid assembly deviations caused by manual tightening and improve assembly efficiency and coaxial accuracy.
[0029] Please see Figure 1 , Figure 2 and Figure 3 The rotating connecting rod 41 is provided with an internal hexagonal hole 411. Through the internal hexagonal hole 411, the operator can insert an internal hexagonal wrench into the internal hexagonal hole 411 of the rotating connecting rod 41. By rotating the wrench, the rotating connecting rod 41 drives the filter head 6 clamped in the filter head limiting mechanism 5 to rotate, thereby driving the filter head 6 to tighten or loosen. This facilitates operation and can effectively improve the tightening accuracy and efficiency during assembly, avoiding axial deviation and overload damage caused by traditional hand-operated tightening.
[0030] Further, please refer to Figure 1 and Figure 2 As shown, the filter head limiting mechanism 5 includes a connecting plate 51, which is fixedly connected to the rotating mounting plate 42 and equipped with a limiting screw 52. A positioning pin 53 is fixedly connected to the limiting screw 52. The positioning pin 53 is engaged in the locking holes on both sides of the filter head 6. The locking holes are preset mounting holes or threaded holes on the filter head 6 body. During installation, the operator aligns the filter head 6 with the rotating mounting plate 42; the limiting screw 52 pushes the positioning pin 53 to gradually extend by rotation; the positioning pin 53 engages in the locking holes on both sides of the filter head 6; this ensures that the filter head 6 does not slide axially or wobble radially or fall off during rotation. After assembly, simply loosen the limiting screw 52 to remove the positioning pin 53 and release the filter head 6.
[0031] Further, please refer to Figure 1 and Figure 3 As shown, the positioning pin 53 is provided with a tapered guide portion 531. The tapered guide portion 531 has a tapered structure with a tapered angle of 15° to 30°, preferably 20°. The positioning pin 53 is made of hardened steel to improve its strength and wear resistance. The outer surface can be coated with a polyurethane layer to prevent damage to the filter head locking hole. During installation, as the positioning pin 53 is pushed, the tapered guide portion 531 can guide it to quickly align and insert into the locking hole of the filter head. Even if there is a slight hole position deviation, it can be automatically corrected through the guide surface, improving assembly efficiency and positioning accuracy.
[0032] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
