Description

Technical Field

[0001] This utility model belongs to the field of filter bag technology, specifically relating to a ring-type filter bag that is easy to replace. Background Technology

[0002] As a filter element, the filter bag is a crucial part of the filtration process, and the quality of the filter bag largely determines the filtration effect for the user.

[0003] Chinese Patent Application No. 202320577975.5 discloses an easily replaceable ring-type filter bag, relating to the field of filter bag technology. This utility model includes: a placement ring with an installation groove; a sliding ring plate slidably mounted on the inner wall of the installation groove; a bag body fixedly mounted to the bottom of the sliding ring plate and extending through the placement ring to its exterior; and an elastic element installed between the bottom of the sliding ring plate and the bottom of the inner wall of the installation groove. This utility model, through the cooperation of the installation groove, sliding ring plate, elastic element, and damper, provides excellent cushioning and shock absorption when the bag body is impacted downwards by liquid, greatly reducing the impact force of the bag body pulling down on the placement ring and avoiding damage caused by the bag body frequently pulling the placement ring due to inertia.

[0004] In the aforementioned patent, when using a bag for filtration, the bag is subjected to the downward impact force of the liquid, which can easily cause tearing damage and affect the normal service life of the bag. In addition, the installation of the placement ring and the installation platform is achieved by using a limiting plate and a clamping plate. However, the limiting plate and the installation platform are connected by a damping shaft. During subsequent use, the limiting plate is prone to rotating and disengaging from the clamping plate under force, affecting the stability of the connection between the limiting plate and the clamping plate, and thus affecting the stability of the installation of the placement ring and the installation platform. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a replaceable ring-type filter bag that features support, protection, and plug-in fixation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped filter bag that is easy to replace, comprising a placement ring, a plurality of clamping plates fixedly connected to the outer side wall of the placement ring, a bag body fixedly connected below the placement ring, an installation platform sleeved around the bag body and below the placement ring, a limiting plate rotatably connected above the installation platform and at the position corresponding to the clamping plates, an insertion assembly provided between the clamping plates and the limiting plate, and a support assembly provided at one lower end of the installation platform.

[0007] Preferably, the support assembly includes a through hole, a support base plate, a connecting rod, a fixing sleeve, and a clamping member. The fixing sleeve is fixedly connected to the bottom of the installation platform. The connecting rod is slidably connected inside the fixing sleeve. A clamping member is provided between the connecting rod and the fixing sleeve. The end of the connecting rod away from the fixing sleeve is fixedly connected to the support base plate. Several through holes are provided on the support base plate.

[0008] Preferably, a limiting slider is fixedly connected to one end of the connecting rod near the fixed sleeve, and a limiting groove is formed on the inner side wall of the fixed sleeve at the position corresponding to the limiting slider.

[0009] Preferably, the clamping component includes a clamping screw, a threaded hole, a clamping disc, and a rubber pad. A threaded hole is provided on the side wall of the fixing sleeve, and the clamping screw is threadedly connected to the inside of the threaded hole. The clamping disc is fixedly connected to one end of the clamping screw near the connecting rod, and a rubber pad is fixedly connected to the side of the clamping disc near the connecting rod.

[0010] Preferably, the plug-in assembly includes a plug-in rod, a movable plate, a connecting spring, a movable groove, and a fixing member. The movable groove is provided inside the card plate, and the movable plate is slidably connected inside the movable groove. A connecting spring is connected between the movable plate and the movable groove. A fixing member is provided between the movable plate and the card plate, and the plug-in rod is fixedly connected to the bottom of the movable plate.

[0011] Preferably, the fixing component includes a fixing screw, a fixing nut, a pushing block, an end plate, and a pushing groove. One end of the moving plate is fixedly connected to the pushing block. A pushing groove is provided on the side wall of the clamping plate at the position corresponding to the pushing block. An end plate is fixedly connected to the side wall of the clamping plate at one end of the pushing groove. A fixing screw is fixedly connected above the end plate. A through hole is provided on the pushing block at the position corresponding to the fixing screw. A fixing nut is threaded onto the outer side wall of the fixing screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a support assembly. The positional relationship between the connecting rod and the fixing sleeve is adjusted according to the size of the bag. The movement of the connecting rod drives the movement of the support base plate. When the support base plate moves to fit against the lower surface of the bag, the clamping screw is rotated, causing it to rotate and move along the threaded hole. The rotation and movement of the clamping screw drives the clamping plate to rotate and move. After the clamping plate moves and fits against the side wall of the connecting rod, the rotation of the clamping screw is stopped. The clamping plate can be used to clamp and fix the connecting rod, and the support base plate can be used to support the bag. After the bag is used to filter the liquid, the filtered liquid is discharged through the through hole, avoiding the support base plate from affecting the liquid discharge operation.

[0014] 2. This utility model is equipped with an insertion assembly. After the limiting plate is rotated and snapped into the inside of the card plate, the pushing block moves along the pushing groove. The movement of the pushing block causes the moving plate to move inside the moving groove. The movement of the moving plate causes the insertion rod to move and the connecting spring to stretch. When the pushing block moves and fits against the side wall of the end plate, the insertion rod is inserted into the inside of the limiting plate. Then, the fixing nut is rotated and screwed onto the fixing screw, so that it fits against the side wall of the pushing block. By using the cooperation of the fixing screw and the fixing nut, the pushing block can be limited, thereby limiting and fixing the moving plate. This ensures the insertion and fixing effect of the insertion rod on the limiting plate, improves the snapping stability between the limiting plate and the card plate, and thus ensures the stability of the placement ring and the installation platform, and improves the stability of the bag installation.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a ring-type filter bag that is easy to replace, including a placement ring 1, a plurality of clamping plates 2 are fixedly connected to the outer side wall of the placement ring 1, a bag body 5 is fixedly connected to the bottom of the placement ring 1, an installation platform 4 is sleeved around the bag body 5 and located below the placement ring 1, a limiting plate 3 is rotatably connected above the installation platform 4 and at the position corresponding to the clamping plates 2, an insertion component 7 is provided between the clamping plates 2 and the limiting plate 3, and a support component 6 is provided at the lower end of the installation platform 4.

[0024] Specifically, the support assembly 6 includes a through hole 61, a support base plate 62, a connecting rod 63, a fixing sleeve 64, and a clamping member 65. The fixing sleeve 64 is fixedly connected to the bottom of the mounting platform 4. The connecting rod 63 is slidably connected inside the fixing sleeve 64. A clamping member 65 is provided between the connecting rod 63 and the fixing sleeve 64. The end of the connecting rod 63 away from the fixing sleeve 64 is fixedly connected to the support base plate 62. The support base plate 62 has several through holes 61.

[0025] By adopting the above technical solution, the positional relationship between the connecting rod 63 and the fixing sleeve 64 is adjusted according to the size of the installed bag body 5. The movement of the connecting rod 63 drives the support base plate 62 to move. When the support base plate 62 moves to fit against the lower surface of the bag body 5, the connecting rod 63 and the fixing sleeve 64 are pressed and fixed by the clamping member 65. The support base plate 62 can support the bag body 5. After the bag body 5 filters the liquid, the filtered liquid is discharged through the through hole 61, avoiding the support base plate 62 from affecting the liquid discharge operation.

[0026] Specifically, a limiting slider is fixedly connected to one end of the connecting rod 63 near the fixed sleeve 64, and a limiting groove is formed on the inner side wall of the fixed sleeve 64 at the position corresponding to the limiting slider.

[0027] By adopting the above technical solution, the connecting rod 63 moves and drives the limiting slider to move inside the limiting groove. Under the sliding cooperation of the limiting slider and the limiting groove, the movement of the connecting rod 63 can be guided. When the limiting slider moves and fits against the side wall of the limiting groove, the limiting slider is blocked and stops moving, thereby preventing the connecting rod 63 from continuing to move and avoiding the connecting rod 63 from detaching from the fixing sleeve 64.

[0028] Specifically, the clamping component 65 includes a clamping screw 651, a threaded hole 652, a clamping disc 653, and a rubber pad 654. The side wall of the fixing sleeve 64 has a threaded hole 652, and the clamping screw 651 is threadedly connected to the inside of the threaded hole 652. The clamping disc 653 is fixedly connected to one end of the clamping screw 651 near the connecting rod 63, and the rubber pad 654 is fixedly connected to the side of the clamping disc 653 near the connecting rod 63.

[0029] By adopting the above technical solution, after the positions of the connecting rod 63 and the fixing sleeve 64 are adjusted, the clamping screw 651 is rotated so that it rotates and moves along the threaded hole 652. The rotation and movement of the clamping screw 651 drives the clamping plate 653 to rotate and move. After the clamping plate 653 moves and fits against the side wall of the connecting rod 63, the rotation of the clamping screw 651 is stopped. The clamping plate 653 can be used to clamp and fix the connecting rod 63. Under the action of the rubber pad 654, the friction between the clamping plate 653 and the connecting rod 63 can be increased, thereby improving the clamping effect of the clamping plate 653 on the connecting rod 63.

[0030] In this embodiment, the bag body 5 is moved through the interior of the mounting platform 4, causing the placement ring 1 to move and fit against the top of the mounting platform 4. Then, the limiting plate 3 is rotated to engage with the inside of the clamping plate 2, facilitating the installation of the placement ring 1 and the mounting platform 4, and thus facilitating the replacement of the bag body 5. The positional relationship between the connecting rod 63 and the fixing sleeve 64 is adjusted according to the size of the bag body 5. The movement of the connecting rod 63 drives the support base plate 62 to move. When the support base plate 62 moves to fit against the lower surface of the bag body 5, the tightening screw 651 is rotated, causing it to rotate along the threaded hole 652. The rotating movement drives the clamping plate 653 to rotate and move. After the clamping plate 653 moves and fits against the side wall of the connecting rod 63, the rotation of the clamping screw 651 stops. The clamping plate 653 can be used to clamp and fix the connecting rod 63. Under the action of the rubber pad 654, the friction between the clamping plate 653 and the connecting rod 63 can be increased, improving the clamping effect of the clamping plate 653 on the connecting rod 63. The supporting base plate 62 can be used to support the bag body 5. After the bag body 5 filters the liquid, the filtered liquid is discharged through the through hole 61, avoiding the supporting base plate 62 from affecting the liquid discharge operation.

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that the plug-in assembly 7 includes a plug-in rod 71, a movable plate 72, a connecting spring 73, a movable groove 74, and a fixing member 75. The movable groove 74 is provided inside the locking plate 2, and the movable plate 72 is slidably connected inside the movable groove 74. A connecting spring 73 connects the movable plate 72 and the movable groove 74. A fixing member 75 is provided between the movable plate 72 and the locking plate 2. The plug-in rod 71 is fixedly connected to the lower part of the movable plate 72.

[0033] Specifically, the fixing component 75 includes a fixing screw 751, a fixing nut 752, a pushing block 753, an end plate 754, and a pushing groove 755. One end of the moving plate 72 is fixedly connected to the pushing block 753. A pushing groove 755 is formed on the side wall of the clamping plate 2 at the position corresponding to the pushing block 753. An end plate 754 is fixedly connected to the side wall of the clamping plate 2 at one end of the pushing groove 755. A fixing screw 751 is fixedly connected above the end plate 754. A through hole is formed on the pushing block 753 at the position corresponding to the fixing screw 751. A fixing nut 752 is threaded onto the outer side wall of the fixing screw 751.

[0034] By adopting the above technical solution, the push block 753 is moved along the push groove 755. After the push block 753 moves to fit the side wall of the end plate 754, the fixing nut 752 is rotated and screwed onto the fixing screw 751, so that it fits against the side wall of the push block 753. By using the cooperation of the fixing screw 751 and the fixing nut 752, the push block 753 can be limited, thereby limiting and fixing the moving plate 72, ensuring the insertion and fixing effect of the plug rod 71 on the limiting plate 3.

[0035] In this embodiment, after the limiting plate 3 is rotated and snapped into the inside of the clamping plate 2, the pushing block 753 is moved along the pushing groove 755. The movement of the pushing block 753 causes the moving plate 72 to move inside the moving groove 74. The movement of the moving plate 72 causes the insertion rod 71 to move and the connecting spring 73 to stretch. When the pushing block 753 moves and fits against the side wall of the end plate 754, the insertion rod 71 is inserted into the inside of the limiting plate 3. Then, the fixing nut 752 is rotated and screwed onto the fixing screw 751, and it is made to fit against the side wall of the pushing block 753. By using the cooperation of the fixing screw 751 and the fixing nut 752, the pushing block 753 can be limited, and the moving plate 72 can be limited and fixed, ensuring the insertion and fixing effect of the insertion rod 71 on the limiting plate 3, improving the snapping stability of the limiting plate 3 and the clamping plate 2, and thus ensuring the stability of the installation of the placement ring 1 and the installation platform 4, and improving the stability of the bag body 5 installation.

[0036] The working principle and usage process of this utility model are as follows: The bag body 5 is moved through the interior of the mounting platform 4, causing the placement ring 1 to move and fit against the top of the mounting platform 4. Then, the limiting plate 3 is rotated to engage with the inside of the clamping plate 2. Next, the pushing block 753 moves along the pushing groove 755. The movement of the pushing block 753 causes the moving plate 72 to move within the moving groove 74. The movement of the moving plate 72 causes the insertion rod 71 to move and the connecting spring 73 to stretch. When the pushing block 753 moves and fits against the side wall of the end plate 754, the insertion rod 71... 1. Then, insert it into the inside of the limiting plate 3, and then rotate the fixing nut 752 onto the fixing screw 751, so that it fits against the side wall of the pushing block 753. By using the cooperation of the fixing screw 751 and the fixing nut 752, the pushing block 753 can be limited, thereby limiting and fixing the moving plate 72, ensuring the insertion and fixing effect of the insertion rod 71 on the limiting plate 3, improving the clamping stability between the limiting plate 3 and the clamping plate 2, and thus ensuring the stability of the installation of the placement ring 1 and the installation platform 4, and improving the safety of the bag body 5. The stability of the installation facilitates the installation of the placement ring 1 and the installation platform 4, thereby facilitating the replacement of the bag body 5. The positional relationship between the connecting rod 63 and the fixing sleeve 64 is adjusted according to the size of the bag body 5. The movement of the connecting rod 63 causes the supporting base plate 62 to move. When the supporting base plate 62 moves to fit against the lower surface of the bag body 5, the tightening screw 651 is rotated, causing it to rotate along the threaded hole 652. The rotation of the tightening screw 651 causes the tightening disc 653 to rotate, and the tightening disc 653 moves to fit against the connecting... After the side wall of rod 63 is closed, the rotating clamping screw 651 is stopped. The clamping plate 653 can be used to clamp and fix the connecting rod 63. Under the action of rubber pad 654, the friction between clamping plate 653 and connecting rod 63 can be increased, improving the clamping effect of clamping plate 653 on connecting rod 63. The supporting base plate 62 can be used to support bag body 5. After the bag body 5 filters the liquid, the filtered liquid is discharged through through hole 61, avoiding the supporting base plate 62 from affecting the liquid discharge operation.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
