Description

Technical Field

[0001] This utility model belongs to the field of filter bag support technology, specifically relating to an arc-shaped outward-turning structure at the top of a bag filter support basket and its processing device. Background Technology

[0002] Liquid bag filters are found in industries such as chemical, steel, metal processing, food, automotive, and electronics. Among the components of liquid bag filters, whether single-bag or multi-bag filters, the built-in support basket is essential. It plays a key role in supporting the filter bags during operation. The support basket is a tool that can withstand filtration pressure differential, protect the filter bags for normal filtration, and extend the life of the filter bags.

[0003] In the processing of the support basket, its overall shape determines the sealing performance of the filter bag in the bag filter. However, the inner diameter of the support basket in the existing technology is circular, which requires a high degree of precision in fitting the filter bag and the support basket when the filter bag is pressed and fixed inside the support basket by the mounting screws to ensure the sealing performance between the filter bag and the support basket. The excessively high processing requirements for the filter bag and the support basket affect the production of the filter bag and the support basket. If the processing precision of the support basket and the filter bag does not meet the requirements, gaps will appear at the connection between the filter bag and the support basket. The liquid to be filtered will flow through the gaps between the support basket and the filter bag, affecting the filtration effect of the bag filter. To address this problem, how to design a top arc-shaped outward-turning structure and processing device for the support basket of a bag filter has become a problem that we need to solve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bag filter support basket with an arc-shaped outward-turning top structure and processing device.

[0005] To achieve the above objectives, this utility model provides a bag filter support basket with an arc-shaped outward-folding top structure, including a support basket, the support basket including a cylindrical body, the bottom of the cylindrical body being fixedly connected to an arc-shaped round bottom, the top of the cylindrical body being fixedly connected to an outward-folding cylinder, and the outer wall of the outward-folding cylinder away from the cylindrical body having an annular edge.

[0006] In the above technical solution, the end of the outward-turning cylinder away from the cylinder body gradually turns outward to form an outward-turning conical profile, and the outward-turning cylinder and the annular edge are integrally formed.

[0007] A processing device for a bag filter support basket with an arc-shaped outward-turning top structure includes a processing unit. The processing unit includes a worktable, a driving component fixedly installed on the top of the worktable, an upper mold fixedly connected to the end of the driving shaft of the driving component, a lower mold fixedly installed inside the worktable, the lower mold being located at the bottom of the upper mold, a demolding sleeve slidably connected to the outer wall of the lower mold, the demolding sleeve slidably connected inside the worktable, a return spring fixedly connected to the bottom of the demolding sleeve, the return spring being fixedly installed inside the worktable, and the return spring being sleeved on the outer wall of the lower mold. The upper and lower molds are used to process and shape the outward-turning cylinder and the annular edge. A feeding assembly is used to assist the operator in automatically feeding the material, and the feeding assembly is connected to the worktable and the demolding sleeve.

[0008] In the above technical solution, the feeding assembly further includes a pressure rod fixedly connected to the outer wall of the demolding sleeve. The end of the pressure rod away from the demolding sleeve passes through the worktable and abuts against a telescopic rod. The telescopic rod is hinged inside the worktable. The outer wall of the telescopic rod has two air holes of different sizes, and a valve is slidably connected inside the larger air hole.

[0009] In the above technical solution, the end of the inner rod of the telescopic rod is fixedly connected to a connecting rod, and the outer wall of the connecting rod is rotatably connected to a sliding member, which is slidably connected inside the worktable.

[0010] In the above technical solution, the top of the sliding member is fixedly connected to a pushing member, the bottom of the pushing member is flush with the top of the demolding sleeve, the outer wall of the pushing member is slidably connected to a material box, the material box is fixedly installed on the top of the worktable, and a baffle is fixedly connected to the side of the material box near the demolding sleeve by bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a feeding component, the processing unit can automatically push the completed and demolded arc-shaped flange structure away from the demolding sleeve during the continuous processing of the arc-shaped flange structure through the upper and lower molds, and push the metal disc to coincide with the demolding sleeve, so as to achieve the effect of automatically feeding and unloading the metal disc, improving the processing efficiency of the arc-shaped flange structure and reducing the probability of workers being crushed. The arc-shaped outward-turning structure formed by the outward-turning cylinder and the annular edge guides the filter bag as it is placed into the support basket, making it easier for workers to put the filter bag into the support basket. The support basket's slightly outward-turning edge creates a conical overall profile, providing a certain degree of elastic sealing. After the filter bag is pressed into the outward-turning cylinder by the installation screw, the support basket, through the outward-turning cylinder with its outward-turning edge, can provide a certain degree of sealing elasticity. This allows for precise adjustment of the strength of the support basket, filter bag, and locking bolts on the installation screw, ensuring the complete sealing integrity of the filter bag installation.

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 The bag filter support basket shown has an arc-shaped outward-turning structure at the top, including a support basket 1. The support basket 1 includes a cylindrical body 101. An arc-shaped round bottom 102 is fixedly connected to the bottom of the cylindrical body 101, and an outward-turning cylinder 103 is fixedly connected to the top of the cylindrical body 101. The cylindrical body 101 is fixedly connected to the arc-shaped round bottom 102 and the outward-turning cylinder 103 by welding to form an integral support basket. The outer wall of the end of the outward-turning cylinder 103 away from the cylindrical body 101 is provided with an annular edge 104. The end of the outward-turning cylinder 103 away from the cylindrical body 101 gradually turns outward to form an outward-turning conical profile. The outward-turning cylinder 103 and the annular edge 104 are integrally set to form an arc-shaped outward-turning structure at the top of the support basket 1. The support basket 1 is used to place the filter bag, providing support for the filter bag to filter inside the bag filter, preventing damage to the filter bag due to excessive pressure (pressure difference), and ensuring normal filtration. The annular edge 104 can form an installation interface on the support basket 1, used to position the support basket 1 inside the bag filter, allowing the support basket 1 to be safely and flatly built into the bag filter, making it convenient for workers to install the support basket 1. The outward-turning cylinder 103 can guide the filter bag when it is placed inside the support basket 1, making it convenient for workers to place the filter bag inside the support basket 1. The outward-turning edge of the support basket 1 forms an overall conical profile, giving it a certain degree of elastic sealing. After the filter bag is pressed into the outward-turning cylinder 103 by the installation screw, the support basket 1 can achieve a certain degree of sealing elasticity through the outward-turning cylinder 103, which is treated by the outward-turning edge. This allows for fine-tuning of the strength of the locking bolts on the support basket 1, filter bag, and installation screw, ensuring the sealing integrity of the filter bag installation, and reducing the processing precision of the filter bag and support basket 1, thus facilitating processing and production.

[0016] like Figures 2 to 4 As shown, a processing device for a bag filter support basket with an arc-shaped outward-folding structure is also disclosed, including a processing unit 2. The processing unit 2 includes a workbench 201. A driving component 202 is fixedly installed on the top of the workbench 201. An upper mold 203 is fixedly connected to the end of the driving shaft of the driving component 202. A lower mold 204 is fixedly installed inside the workbench 201. The lower mold 204 is located at the bottom of the upper mold 203. A demolding sleeve 205 is slidably connected to the outer wall of the lower mold 204. The demolding sleeve 205 is slidably connected inside the workbench 201. A return spring 206 is fixedly connected to the bottom of the demolding sleeve 205. The return spring 206 is fixedly installed inside the workbench 201 and sleeved on the outer wall of the lower mold 204. The upper mold 203 and the lower mold 204 are used to process and shape the outward-folding cylinder 103 and the annular edge 104. A feeding component is used to assist the operator in automatic feeding. The feeding component is connected to the workbench 201 and the demolding sleeve 205. like Figures 3 to 4As shown, the feeding assembly includes a pressure rod 207 fixedly connected to the outer wall of the demolding sleeve 205. One end of the pressure rod 207, away from the demolding sleeve 205, passes through the worktable 201 and abuts against a telescopic rod 208. The telescopic rod 208 is a spring-loaded piston telescopic rod, a commonly used component in the prior art, and therefore will not be described in detail. The telescopic rod 208 is hinged inside the worktable 201. Two air holes 209 of different sizes are opened on the outer wall of the telescopic rod 208. A valve 210 is slidably connected inside the larger air hole 209. A connecting rod 211 is fixedly connected to the end of the inner rod of the telescopic rod 208. A sliding member 212 is rotatably connected to the outer wall of the connecting rod 211. The sliding member 212 is slidably connected inside the worktable 201. A pushing member 213 is fixedly connected to the top of the sliding member 212. The bottom of the pushing member 213 is flush with the top of the demolding sleeve 205. A material box 214 is slidably connected to the wall and is fixedly installed on the top of the workbench 201. A pusher 213 is slidably connected to the bottom of the inner wall of the material box 214. The overall height of the pusher 213 is less than the height of the metal disc, so that the pusher 213 can only push one metal disc at a time. A baffle 215 is fixedly connected to the side of the material box 214 near the demolding sleeve 205 by bolts. The operator can adjust the opening height of the baffle 215 and the material box 214 by bolts, so that the pusher 213 can only push one metal disc out of the material box 214 at a time. Excess metal discs will be blocked by the baffle 215, so that when the pusher 213 pushes one metal disc, the metal discs will be pushed together due to friction. The arc contour of the pusher 213 near the demolding sleeve 205 is adapted to the contour of the demolding sleeve 205.

[0017] Working principle: When the operator needs to process the arc-shaped outward-turned structure on the support basket 1, the metal disc to be stretched (the metal disc matches the top contour of the lower die 204) is first placed into the material box 214. Then, the processing unit 2 is controlled by the control panel, which causes the drive component 202 on the processing unit 2 to control the upper die 203 to descend. The upper die 203 descends and cooperates with the lower die 204 to stretch and form (initially under air pressure). The upper die 203 then pushes the demolding sleeve 205 to slide down along the outer wall of the lower die 204 and compresses the return spring 206 to retract. The demolding sleeve 205 drives the pressure rod 207 to descend and push the telescopic rod 208 to rotate. The rotation of the telescopic rod 208 will drive the sliding part 21 through the connecting rod 211. 2. Sliding along the inside of the worktable 201, the spring inside the telescopic rod 208 unfolds, allowing the telescopic rod 208 to draw in external gas through the two air holes 209. At this time, the valves 210 on the air holes 209 are opened by the negative pressure generated by the unfolding telescopic rod 208, allowing air to enter. The sliding component 212 slides, causing the pushing component 213 to gradually move away from the demolding sleeve 205 until the upper mold 203 and lower mold 204 are fully engaged. The upper mold 203 stops pressing the demolding sleeve 205 and stops descending. At this time, the demolding sleeve 205 stops pressing the telescopic rod 208 to rotate through the pressure rod 207, and the telescopic rod 208 stops driving the sliding component 212 to slide through the connecting rod 211. The sliding component 212 drives the pushing component 213 to move to a position far enough away from the demolding sleeve 205, so that the pushing component... The moving part 213 disengages from the bottom of the metal disc inside the material box 214, allowing the metal disc placed inside the material box 214 to fall into the arc of the pushing part 213 near the demolding sleeve 205. Then, the driving part 202 drives the upper mold 203 to reset, so that the demolding sleeve 205 is no longer squeezed by the upper mold 203 and can be pushed back to its original position by the reset spring 206. The reset of the demolding sleeve 205 will drive the pressure rod 207 to stop the pressure on the telescopic rod 208. At this time, the spring inside the telescopic rod 208 drives the telescopic rod 208 to retract and reset, so that the inner rod of the telescopic rod 208 pulls the sliding part 212 to reset through the connecting rod 211. In turn, the sliding part 212 drives the pushing part 213 to push the metal disc towards the demolding sleeve 205 until the pushing part 213 pushes the metal disc. The movement stops after aligning with the top of the demolding sleeve 205. As the upper mold 203 continues to descend, the metal discs inside the material box 214 are continuously pushed and positioned at the top of the demolding sleeve 205. This pushes the demolding sleeve 205 off the lower mold 204, removing the completed arc-shaped outward-facing structure from the top of the demolding sleeve 205. This achieves automatic loading and unloading of the metal discs, improving the processing efficiency of the arc-shaped outward-facing structure and reducing the probability of workers being injured. It should be noted that when the telescopic rod 208 is reset by the internal spring, the gas inside the telescopic rod 208 will be discharged through the two air holes 209. At this time, the valve 210 is pushed by the gas to close the corresponding 109, allowing the telescopic rod 208 to exhaust gas only through one air hole 209.This reduces the reset speed of the telescopic rod 208, allowing the demolding sleeve 205 to demold and reset the arc-shaped outward-facing structure stretched and formed on the lower mold 204. Only then will the pushing component 213 push the metal disc to push the demolded arc-shaped outward-facing structure away from the demolding sleeve 205, aligning the metal disc with the top of the demolding sleeve 205 and preventing jamming.
