Description

Technical Field

[0001] This application relates to the technical field of sludge drying equipment, and more particularly to a filter fixing structure and a sludge dryer. Background Technology

[0002] In recent years, with the development of sludge drying technology, low-temperature sludge drying technology has gradually become one of the mainstream technologies for sludge treatment and disposal in my country. Low-temperature sludge drying technology is a treatment technology that uses hot, dry air generated by a low-temperature drying system to circulate within the system and dry strips of sludge evenly distributed on a mesh belt. As an important component of a sludge dryer, the installation stability of the filter is crucial to the overall machine. However, existing fixing structures generally use vertical clamps to fix the filter, that is, clamps are used to press the filter from the bottom edge above. This fixing method uses a large number of clamps, and because of the large number and difficulty in disassembly and assembly, maintenance is inconvenient. Utility Model Content

[0003] The purpose of this application is to provide a filter fixing structure and a sludge dryer, wherein the locking member is locked by a hinge to secure the fixing member, thereby effectively fixing the filter, and is easy to assemble and disassemble.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On the one hand, a filter fixing structure and a sludge dryer are provided, including:

[0006] A fixed frame is used to mount the filter;

[0007] A fastener is provided above the bottom edge of the filter and clamps the filter with the fixing frame. Both ends of the fastener are provided with locking grooves that extend vertically.

[0008] The locking assembly includes a support mounted on the fixed frame, a movable rod hinged to the support, and a locking member movably mounted on the movable rod. The movable rod is movable relative to the support between a first position and a second position. In the first position, the movable rod is located within the locking groove and at least partially above the fixed member. The locking member is movable relative to the movable rod in a first direction, thereby contacting and locking the fixed member with the upper surface of the fixed member. In the second position, the movable rod disengages from the locking groove.

[0009] Furthermore, at least two fasteners are provided, and the two fasteners are spaced apart along the second direction above the bottom edge of the filter.

[0010] Furthermore, at least four locking components are provided, with each pair of locking components disposed at both ends of the same fixing member along a third direction, wherein the second direction and the third direction are perpendicular to each other.

[0011] Furthermore, the support is provided with a U-shaped mounting groove, and one end of the movable rod is hinged to the mounting groove.

[0012] Furthermore, the movable rod and the support are rotatably connected via a rotating shaft.

[0013] Furthermore, the locking element includes a sleeve movably fitted onto the upper part of the movable rod, and a ring disposed on the sleeve.

[0014] Furthermore, the sleeve and the movable rod are threaded together so that the sleeve can be moved axially relative to the movable rod by rotating the ring, thereby making the sleeve contact and lock with the upper surface of the fixing member.

[0015] Furthermore, it also includes a limiting plate and a vibration damper, the limiting plate being disposed above the filter along the second direction, and the vibration damper being disposed on the limiting plate.

[0016] Furthermore, it also includes multiple buffers, which are disposed at the four corners of the bottom of the fixed frame.

[0017] On the other hand, a sludge dryer is also provided, including a filter and a filter fixing structure as described in any of the above.

[0018] The beneficial effects of this application are as follows: The design of the locking assembly is the core of this application. It includes a support mounted on a fixed frame, a movable rod hinged to the support, and a locking element movably mounted on the movable rod. The movable rod can move flexibly between a first position and a second position relative to the support. When the movable rod is in the first position, it is precisely inserted into the locking groove of the fixed element. At this time, the locking element can move freely along the axial direction of the movable rod until it comes into close contact with the upper surface of the fixed element, thereby firmly locking the fixed element and achieving stable fixation of the filter. When it is necessary to disassemble the filter, simply move the movable rod to the second position to disengage it from the locking groove, and then the locking element can be easily released to complete the filter disassembly. This design not only simplifies the filter installation and disassembly process and improves maintenance efficiency, but also reduces manufacturing costs by reducing the number of clips and optimizes the overall structure. At the same time, because the disassembly and assembly process is simple and quick, users can perform equipment inspection and maintenance more frequently, promptly identify and deal with potential safety hazards, thereby improving the safety and reliability of the sludge dryer. In summary, the filter fixing structure and sludge dryer of this application, through innovative locking component design, achieve efficient, stable, and convenient fixing of the filter, bringing significant technological progress and practical application value to the sludge treatment industry.

[0027] like Figure 1-Figure 3 As shown, this embodiment provides a filter fixing structure, including: a fixing frame 1, a fixing member 2, and a locking assembly 3. The fixing frame 1 is used to install a filter 110; the fixing member 2 is disposed above the bottom edge of the filter 110 and clamps the filter 110 with the fixing frame 1. Both ends of the fixing member 2 are provided with locking grooves 201 that extend vertically through the filter; the locking assembly 3 includes a support 301 mounted on the fixing frame 1, a movable rod 302 hinged to the support 301, and a locking member 303 movably mounted on the movable rod 302. The movable rod 302 can move relative to the support 301 between a first position and a second position. When in the first position, the movable rod 302 is located in the locking groove 201 and at least partially above the fixing member 2. The locking member 303 can move relative to the movable rod 302 in a first direction, thereby contacting and locking the fixing member 2 with the upper surface of the fixing member 2; when in the second position, the movable rod 302 disengages from the locking groove 201.

[0028] Based on the above scheme, the fixed frame 1 serves as the foundation for installing the filter 110, providing a stable support platform for the filter 110. The fixing member 2 is positioned above the bottom edge of the filter 110, working together with the fixed frame 1 to clamp and secure the filter 110. The fixing member 2 has vertically penetrating locking grooves 201 at both ends, designed to cooperate with the movable rod 302 in the locking assembly 3 to achieve a locking function. The support 301 is mounted on the fixed frame 1, serving as a support point for the movable rod 302. The movable rod 302 is hinged to the support 301, allowing it to move between a first position and a second position relative to the support 301. In the first position, the movable rod 302 is located within the locking groove 201, ensuring that the locking member 303 can lock the fixing member 2. In the second position, the movable rod 302 disengages from the locking groove 201, facilitating unlocking and disassembly. The locking member 303 is movably mounted on the movable rod 302, allowing it to move along a first direction. When the movable rod 302 is in the first position, the locking member 303 can move downwards to contact and lock the fixing member 2, thereby fixing the filter 110. The installation process based on this structure is as follows: First, place the filter 110 in the fixing frame 1 and initially clamp it using the fixing member 2. Then, move the movable rod 302 to the first position, allowing it to enter the locking groove 201 of the fixing member 2. Next, move the locking member 303 axially along the movable rod 302, making it contact and lock with the upper surface of the fixing member 2, thus completing the fixing of the filter 110. Disassembly process: When it is necessary to disassemble the filter 110, first move the locking member 303 axially along the movable rod 302, separating it from the fixing member 2. Then, move the movable rod 302 out of the locking groove 201 to the second position, at which point the filter 110 can be easily disassembled.

[0029] Overall, the hinged movable rod 302 and the movable locking element 303 design make the installation and disassembly of the filter 110 simple and quick, greatly improving maintenance efficiency. Due to the ease of installation and disassembly, inspections and maintenance can be performed more frequently, allowing for the timely detection and handling of potential safety hazards, thus improving the safety and reliability of the equipment. The clamping design between the fixing element 2 and the fixing frame 1, and the locking effect of the locking element 303 on the fixing element 2, together ensure the stability of the filter 110 during installation, preventing loosening due to vibration or external force. Compared to traditional vertical snap-fit ​​fixing methods, the design of this application significantly reduces the number of snaps, lowers manufacturing costs, and simplifies the structure.

[0030] It should be noted that the locking member 303 contacting and locking the upper surface of the fixing member 2 specifically means that when the locking member 303 moves along the first direction to contact the upper surface of the fixing member 2, the bottom of the locking member 303 presses against the upper surface of the fixing member 2, that is, the locking member 303 presses the fixing member 2 from above, thereby locking the fixing member 2.

[0031] Furthermore, to enhance the fixing effect and stability of the filter 110, the fixing member 2 in this application is designed to include at least two members, and these two fixing members 2 are spaced apart above the bottom edge of the filter 110 along a second direction (which can be the length direction of the filter 110 or other directions determined according to specific installation requirements). This layout ensures that the filter 110 is evenly supported and clamped at multiple points, effectively preventing loosening or deformation caused by uneven force or vibration at a single point. Each fixing member 2 is equipped with a vertically penetrating locking groove 201 at both ends, which cooperates with the movable rod 302 in the locking assembly 3. When the two movable rods 302 are in the locked position, they can be inserted into the locking grooves 201 of the two fixing members 2 respectively, and make close contact with the upper surface of the fixing member 2 through the locking member 303, achieving a double locking effect. This double locking mechanism not only enhances the fixing stability of the filter 110, but also improves the redundancy and reliability of the entire fixing structure.

[0032] Furthermore, the spacing between the two fasteners 2 facilitates adjustment of the filter 110's position or partial maintenance when needed. Users can selectively loosen the locking assembly 3 on one fastener 2 to fine-tune or inspect the filter 110, without having to completely disassemble the entire filter 110. This flexibility further improves equipment maintenance efficiency and user experience.

[0033] Furthermore, at least four locking components 3 are provided, with each pair of locking components 3 positioned at both ends of the same fixing member 2 along a third direction. This layout design ensures that each fixing member 2 is effectively locked at its two key endpoints, thus forming a more stable fixing structure. Specifically, each fixing member 2 has locking grooves 201 at both ends for engaging with the corresponding locking component 3. Each pair of locking components 3 is mounted on the fixing frame 1 via their respective supports 301, and the movable rods 302 are hinged to the supports 301 and can move between a first position and a second position. When the movable rods 302 are in the first position, they simultaneously insert into the locking grooves 201 at both ends of the fixing member 2, and then the locking components 303 move axially along the movable rods 302, making tight contact with the upper surface of the fixing member 2 to achieve a secure locking effect. Since the second direction and the third direction are perpendicular, this layout not only enhances the stability of the filter 110 in the second direction but also ensures its stability in the third direction. Even under harsh operating conditions such as vibration or impact, the filter 110 maintains a stable and fixed position, avoiding safety hazards caused by loosening or detachment. Furthermore, the redundant design of the four locking components 3 enhances the reliability and durability of the entire fixing structure. Even if one or more locking components 3 fail, the others can continue to operate, ensuring the secure fixing of the filter 110. This design provides users with enhanced safety and reduces the risk of downtime due to single-point failures.

[0034] In some embodiments, to further optimize the structure and installation convenience of the locking assembly 3, the support 301 is designed to include a U-shaped mounting groove. This U-shaped mounting groove provides a precise hinge point for one end of the movable rod 302, allowing the movable rod 302 to rotate and move stably and flexibly relative to the support 301. One end of the movable rod 302 is fixed to the bottom or side wall of the U-shaped mounting groove by a hinge (such as a pin, hinge, etc.), ensuring that the movable rod 302 can swing freely within a certain range. When it is necessary to adjust the position of the movable rod 302, the user can push or pull the movable rod 302 to rotate it around the hinge point, thereby changing the relative position of the movable rod 302 and the locking groove 201 of the fixing member 2. The design of the U-shaped mounting groove not only simplifies the structure of the support 301 but also improves the accuracy and stability of the installation of the movable rod 302. Since the shape of the mounting groove matches one end of the movable rod 302, it can be ensured that the movable rod 302 will not deviate from the predetermined trajectory during rotation, thereby ensuring the reliability and durability of the locking assembly 3.

[0035] Specifically, the movable rod 302 and the support 301 are rotatably connected via a rotating shaft 304. The rotating shaft 304 is precisely installed inside the support 301, typically passing through a hole or groove in the support 301, and mates with one end of the movable rod 302. This end of the movable rod 302 is designed with a hole or groove that matches the rotating shaft 304, so that when the movable rod 302 is assembled with the support 301, the rotating shaft 304 can be inserted into the hole or groove of the movable rod 302, thereby achieving a tight connection between the two. The rotating shaft 304 not only provides the axis of rotation for the movable rod 302 but also ensures the stability and smoothness of the movable rod 302 during rotation. Because the rotating shaft 304 typically has high precision and wear resistance, it can maintain low friction and wear during long-term use, extending the service life of the locking assembly 3.

[0036] Generally, the locking element 303 includes a sleeve 3031 movably fitted onto the upper part of the movable rod 302, and a ring 3032 disposed on the sleeve 3031. The sleeve 3031 is designed to slide freely along the axial direction of the movable rod 302, which is the basis for realizing the locking and unlocking functions. When the movable rod 302 is in the locked position (i.e., the first position), the sleeve 3031 moves downward along the movable rod 302 until its lower end contacts the upper surface of the fixing element 2. At this time, the friction or pressure generated between the sleeve 3031 and the fixing element 2 will prevent the filter 110 from moving, thereby achieving the locking effect. The ring 3032 is disposed on the outer surface of the sleeve 3031, and its main function is to increase the contact area between the locking element 303 and the operator, making it easier for the user to operate. For example, the user can control the movement of the locking element 303 by grasping the ring 3032 and applying appropriate force to push or pull the sleeve 3031. In addition, the ring 3032 can also serve as a visual marker to help users determine whether the locking element 303 is in the correct position.

[0037] It should be noted that the specific structure of the locking element 303 may be adjusted and optimized according to the actual application requirements. For example, the materials, dimensions, and shapes of the sleeve 3031 and the ring 3032 can be selected and designed according to factors such as the weight, size, and working environment of the filter 110. At the same time, in order to ensure the stability and durability of the locking element 303, its manufacturing process and assembly precision need to be strictly controlled.

[0038] Furthermore, to further improve the ease of operation and locking effect of the locking element 303, a threaded engagement is adopted between the sleeve 3031 and the movable rod 302. This design allows the user to drive the sleeve 3031 to move axially relative to the movable rod 302 by rotating the ring 3032, thereby achieving tight contact and locking between the sleeve 3031 and the upper surface of the fixing element 2. Specifically, the inner wall of the sleeve 3031 is provided with a threaded groove that matches the external thread of the movable rod 302. When the user rotates the ring 3032, the rotational force of the ring 3032 is transmitted to the sleeve 3031. Due to the threaded engagement between the sleeve 3031 and the movable rod 302, this rotational force is converted into linear motion of the sleeve 3031 along the axial direction of the movable rod 302. As the sleeve 3031 moves downward, its lower end gradually approaches and eventually contacts the upper surface of the fixing element 2, generating sufficient friction or pressure to prevent the filter 110 from moving, thereby achieving the locking effect. This threaded fit design not only improves the ease of operation of the locking element 303, but also makes the locking process smoother and more reliable. Users can rotate the ring 3032 as needed to precisely control the movement distance of the sleeve 3031, thereby achieving fine-tuning of the locking degree of the filter 110. Furthermore, due to the self-locking characteristic of the threaded fit, once the sleeve 3031 contacts and locks with the fixing element 2, the locking element 303 can maintain a stable locking state even without external force.

[0039] In some embodiments, the system further includes a limiting plate 4 and a vibration damper 5. The limiting plate 4 is disposed above the filter 110 along a second direction, and the vibration damper 5 is disposed on the limiting plate 4. The main function of the limiting plate 4 is to limit and fix the filter 110 from above. The size and shape of the limiting plate 4 can be designed according to the specific size and layout of the filter 110 to ensure that it can fully cover and stably define the filter 110. The vibration damper 5 is installed on the limiting plate 4 to reduce the impact of vibration on the filter 110 and the entire device. The vibration damper 5 typically has elastic or damping characteristics, which can absorb some energy when vibration occurs and convert it into heat or other forms of energy dissipation. This not only reduces the vibration amplitude and frequency of the filter 110, but also extends its service life and reduces noise pollution. During installation, the vibration damper 5 can be adjusted as needed to ensure that it can provide appropriate damping effect. At the same time, the combined design of the limiting plate 4 and the vibration damper 5 can also improve the installation accuracy and stability of the filter 110, making it more adaptable to various complex working environments.

[0040] Simultaneously, it also includes multiple buffer elements 6, which are disposed at the four corners of the bottom of the fixed frame 1. These buffer elements 6 are typically made of materials with high elasticity and good shock absorption properties, such as rubber, springs, or polyurethane. Their main function is to absorb and disperse the energy when the filter 110 is subjected to external vibration or impact, thereby protecting the filter 110 and its fixing structure from damage. The placement of the buffer elements 6 at the four corners of the bottom of the fixed frame 1 is based on mechanical principles. These four locations are key points of contact between the fixed frame 1 and the supporting structure (such as the frame of a sludge dryer), and are also the easiest paths for vibration and impact to be transmitted. By installing buffer elements 6 at these locations, the propagation path of vibration and impact can be effectively blocked, reducing its impact on the filter 110 and other parts of the equipment.

[0041] Furthermore, the number and layout of the buffer components 6 can be adjusted according to actual needs. For example, in working environments with high vibration, the number of buffer components 6 can be increased or more efficient buffering materials can be used to improve the shock absorption effect. At the same time, the installation of the buffer components 6 should be ensured to be firm and reliable to avoid loosening or falling off during long-term use.

[0042] On the other hand, a sludge dryer is also provided, including a filter 110 and a filter fixing structure as described in any of the above.
