Description

Technical Field

[0001] This invention belongs to the technical field of dust removal equipment, specifically a bottom-mounted bag cage and its installation method. Background Technology

[0002] With industrial development, industrial production generates large amounts of harmful fumes, which seriously endanger human health and damage the ecological environment. Currently, baghouse dust collection is the main method for treating waste gas in large-scale industries, and filter bags are a key component in the operation of dust collectors. Filter bags are required to be able to efficiently filter dust, be easy to replace, and be easy to clean. However, with existing bag cages, dust accumulates inside, requiring the filter bags to be removed for cleaning. This repeated installation and removal is inconvenient. While bag cages are typically installed from top to bottom, some factory buildings are not tall enough, with the top of the baghouse dust collector approaching the building's ceiling. Furthermore, installing bag cages from top to bottom requires workers to climb to the top of the baghouse dust collector to transport the bag cage and filter bags for installation, which is difficult and dangerous due to the height of the work. Therefore, we propose a bottom-loading bag cage and its installation method to improve operational safety and installation feasibility. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a technical solution: see Figure 1 , 2 The bottom-mounted bag cage has a cage frame structure to support the filter bag. The cage frame is a circular cage-like structure formed by multiple supporting ribs 2. Several reinforcing rings 3 are provided inside the cage frame. The reinforcing rings 3 are ring-shaped structures, and each reinforcing ring 3 is connected to each supporting rib 2. In this embodiment, there are 12 supporting ribs 2, which are vertical, parallel, and evenly arranged in a ring.

[0029] The upper part of the cage frame is provided with several clamping ribs 1, and the bottom of the clamping ribs 1 is fixedly connected to the inside of the cage frame. The upper part of the clamping rib 1 is provided with an outwardly bent guide hook 11, and the upper part of the clamping rib 1 extends out of the cage frame. The middle part of the clamping rib 1 is provided with an elastic bend 13 to give the clamping rib 1 an outward elastic force. The upper part of the elastic bend 13 is provided with a positioning groove 12, which engages with the inner side of the reinforcing ring 3 provided on the upper part of the cage frame, so that the clamping rib 1 can move inward after being subjected to inward compressive force, and has an outward elastic restoring force. In this embodiment, there are 3 clamping ribs 1.

[0030] See Figure 2The bottom of the clamp 1 is fixedly connected to two reinforcing rings 3 to ensure its installation stability.

[0031] See Figure 2 The elastic bend 13 has a triangular structure and bends towards the center of the cage. In other embodiments, the elastic bend 13 may have an arc-shaped structure.

[0032] In this embodiment, the supporting ribs 2, reinforcing rings 3, and clamping ribs 1 in the cage are welded together and fixed. All weld points are uniformly welded, and the outer surface of the cage is smooth and clean.

[0033] See Figure 1 The bottom of the cage has a base 4, which is a platform structure.

[0034] The bag cage and filter bag are used together. The filter bag is an external filter type, which blocks dust on the outside of the filter bag during filtration. The inside of the filter bag is supported by the bag cage. The filter bag includes a bag body 6, and an expansion ring 5 is fixedly connected to the upper end of the bag body 6. The expansion ring 5 is sewn inside the bag body 6. The bag body 6 is a dust collector bag.

[0035] The cage frame is made of stainless steel, making it easy to manufacture, weld, and assemble.

[0036] The installation method for bottom-loading bag cages includes the following steps:

[0037] S1: Manufacture the cage and filter bag according to the design requirements;

[0038] S2: Insert the filter bag into the cage from bottom to top, ensuring that at least one clamping rod 1 does not protrude through the expansion ring 5;

[0039] S3: The cage is raised from bottom to top and installed into the housing of the bag filter, with the upper part of the cage protruding through the perforated plate 7 at the top of the bag filter.

[0040] S4: Pull the filter bag down so that the clamping rib 1 passes through the expansion ring 5 and the expansion ring 5 is secured to the periphery of the orifice plate 7;

[0041] S5: Move the cage frame downwards so that the guide hook 11 of the clamp rib 1 hooks onto the outer edge of the expansion ring 5, completing the fixing and installation. See also Figure 3 , 4 5.

[0042] Furthermore, in step S1, after the drawings are designed, the cages and filter bags are processed and manufactured according to the data drawn in the drawings. The cages are made of high-strength and wear-resistant materials, and their number is the same as the number of perforated plates 7.

[0043] The steps for drawing design are as follows:

[0044] A1: Understand the plan, comprehend the design intent, and the direction of the design;

[0045] A2: Implement the overall plan in CAD, that is, draw the draft, and then adjust and standardize the dimensions in the overall plan according to the specifications and your own experience;

[0046] A3: Check the vertical alignment and slope contour lines of the CAD master plan according to the plan;

[0047] A4: Frame the overall plan, divide it into partial plans, and then index out the detailed plans of each node and component;

[0048] A5: Start drawing detailed drawings and transfer the completed detailed drawings to the CAD master plan;

[0049] A6: Check for errors in the drawing data.

[0050] Furthermore, in step S2, in the combination of filter bag and cage, at least one clamping bar 1 does not protrude through the expansion ring 5, and at least one clamping bar 1 protrudes through the expansion ring 5, so that the expansion ring 5 enters the perforated plate 7 at an angle, can be squeezed and contracted, and smoothly protrude through the perforated plate 7.

[0051] Furthermore, in step S3, inside the bag filter housing, the top of the cage and filter bag assembly is raised and passes through the perforated plate 7. The clamping ribs 1 at the top of the cage are elastic and contract inward, and the outer edge of the guide barb 11 at the top of the clamping rib 1 is a smooth bending structure, which can smoothly pass through the perforated plate 7.

[0052] Furthermore, a groove 51 is provided on the outer periphery of the expansion ring 5. After the expansion ring 5 expands and resets, the groove 51 engages with the edge of the hole in the perforated plate 7. The inner layer of the expansion ring 5 is made of a steel ring strip. After determining the size of the expansion ring according to the diameter of the hole in different plates, the outer layer is a rubber sleeve. The steel ring expands the rubber sleeve to achieve a tight fit between them, making them a single unit, and allowing the groove 51 to engage with the perforated plate 7 for fixed installation.
