Description

Technical Field

[0001] This utility model belongs to the field of filter bag technology, and specifically provides a flat dust collector cage and filter bag. Background Technology

[0002] In the application of traditional flat dust collector filter bags, the cage serves as the core support component, and its structural design directly affects the filter bag's lifespan and dust collection efficiency. Traditional flat filter bag cages typically have annular support rings welded internally, with multiple short rods welded inside the support rings for reinforcement. This design relies on resistance welding to connect the short rods to the support rings, but it has significant drawbacks: First, the strength of the resistance welds cannot be guaranteed; under long-term vibration or high-load conditions, the weld points are prone to loosening or breaking, leading to structural instability. Second, the weld points of the short rods protrude from the support ring surface, easily rubbing against the inner wall of the filter bag, wearing down the filter bag material, shortening its lifespan, and even causing leakage problems. Furthermore, the traditional structure lacks uniform support, potentially causing localized stress concentration in the filter bag, affecting airflow distribution and dust collection efficiency. Therefore, there is an urgent need in this field for an improved flat dust collector cage to address the issues of weld strength and wear. Utility Model Content

[0003] To solve the above problems, this utility model provides a flat dust collector cage and filter bag.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flat dust collector cage, comprising a frame, a fixed seat fixedly installed at one end of the frame, and a base fixedly installed at the other end of the frame. The frame includes a support rod and a support ring. The two ends of the support rod are respectively welded to the outer wall of the fixed seat and the inner wall of the base. The support ring is welded to the inner side of the support rod. The support ring is recessed to form a support recess, and the outer end of the support recess is welded to it.

[0005] Furthermore, the surface of the fixing base has an opening, and reinforcing plates are uniformly fixedly installed on the inner wall of the fixing base.

[0006] Furthermore, the number of the support recesses is no less than two.

[0007] Furthermore, a slot is provided in the middle of the support recess, a reinforcing plate is inserted into the slot, a limiting block is fitted on the side wall of the reinforcing plate, and the limiting block is located in the recess of the support recess.

[0008] A flat dust collector filter bag includes the aforementioned flat dust collector cage and a filter bag, wherein the filter bag is fitted on the outside of the cage and the open end of the filter bag is fitted on the outside of the fixing seat.

[0009] Furthermore, an annular support plate is fixedly installed on the outer wall of the fixing base, and an installation cover is fixedly installed on the surface of the annular support plate, with the opening end of the filter bag located between the annular support plate and the installation cover.

[0010] The beneficial effects of using this utility model are: This invention features support recesses machined on the support ring and corresponding support recesses welded together. The integrated design enhances the overall rigidity of the frame, reduces the risk of welding point loosening, and is suitable for high-vibration environments.

[0011] The design of the support recess in this utility model makes the surface of the support ring smooth and without protruding welding points, thereby reducing friction with the inner wall of the filter bag. After the filter bag is fitted on the outside of the frame, the support recess provides uniform support, prevents local stress concentration, and effectively reduces wear and damage.

[0012] This invention inserts a reinforcing plate into the support recess and fixes it with a limiting block, which significantly improves the local rigidity and deformation resistance without increasing external protrusion. The reinforcing plate is firmly positioned and not easy to loosen, so that the cage can withstand higher vibration and impact loads, while maintaining low friction characteristics and extending the filter bag life.

[0018] 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.

[0019] Example 1

[0020] Reference Figure 1 and Figure 2 A flat dust collector cage includes a frame 1, with a fixed base 2 fixedly installed at one end of the frame 1 and a base 3 fixedly installed at the other end of the frame 1. The frame 1 includes a support rod 11 and a support ring 12. The two ends of the support rod 11 are respectively welded to the outer wall of the fixed base 2 and the inner wall of the base 3. The support ring 12 is welded to the inner side of the support rod 11. The support ring 12 is recessed to form a support recess 121, and the outer end of the support recess 121 is welded to the support rod 11.

[0021] The support ring 12 is stamped with support recesses 121 by a stamping equipment, so that the inner support structure and the support ring 12 are integrated into one, which improves the overall stability and enhances the overall rigidity. At the same time, it makes the surface of the support ring 12 smooth and without protruding welding points, reducing friction with the inner wall of the filter bag 4 and effectively avoiding wear and damage to the filter bag 4.

[0022] The two ends of the support recess 121 are perpendicular to the support ring 12, effectively providing support force.

[0023] Specifically, the surface of the fixing base 2 has an opening, and the inner wall of the fixing base 2 is uniformly fixed with reinforcing plates 21 to support the opening of the fixing base 2.

[0024] Specifically, the number of support recesses 121 is no less than two.

[0025] The number of support recesses 121 can be adjusted according to the actual application scenario or the size of the flat dust collector cage to achieve an effective support effect.

[0026] Example 2

[0027] Reference Figure 3 The difference from Example 1 is that: A slot is provided in the middle of the support recess 121, and a reinforcing plate 122 is inserted into the slot. A limiting block 123 is installed on the side wall of the reinforcing plate 122, and the limiting block 123 is located in the recess of the support recess 121.

[0028] In certain industrial dust removal scenarios with high load and high frequency vibration, the support recess 121 itself may still be at risk of excessive local stress and fatigue deformation. In severe cases, the weld of the support recess 121 in Embodiment 1 may break, affecting the support effect of the support ring 12.

[0029] By setting a reinforcing plate 122 at the support recess 121, the structural strength of this key stress-bearing part is further enhanced. At the same time, the setting of the limiting block 123 realizes the precise positioning and reliable locking of the reinforcing plate 122, avoiding the movement or failure of the reinforcing plate 122 in the working state. The overall strength of the support ring 12 is enhanced, providing better impact resistance and improving the durability of the application.

[0030] Example 3

[0031] Reference Figure 4 A flat dust collector filter bag includes a flat dust collector cage as described in Embodiment 1 or Embodiment 2, and also includes a filter bag 4. The filter bag 4 is sleeved on the outside of the cage 1, and the open end of the filter bag 4 is assembled on the outside of the fixing seat 2.

[0032] Specifically, an annular support plate 22 is fixedly installed on the outer wall of the fixing base 2, and an installation cover 5 is fixedly installed on the surface of the annular support plate 22. The opening end of the filter bag 4 is located between the annular support plate 22 and the installation cover 5.

[0033] The installation of the cover 5 and the filter bag 4 facilitates the installation and replacement of the filter bag 4, simplifying the installation and maintenance process and reducing maintenance costs.

[0034] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
