Description

Technical Field

[0001] This utility model relates to the field of vacuum automatic feeding technology, and in particular to a vacuum automatic feeding device. Background Technology

[0002] In industrial material handling, vacuum automatic feeding devices are widely used due to their efficient and clean material transfer capabilities. Their core filtration system relies on filter elements within the dust collector to filter the conveyed gas, intercepting dust particles and ensuring stable feeding and equipment cleanliness. However, in actual operation and maintenance, disassembling and installing filter elements requires individual operation with tools, making the process cumbersome. Workers must tighten and loosen each filter element one by one, which is not only time-consuming but also prone to human error, leading to filter damage or improper installation. Utility Model Content

[0003] The purpose of this invention is to solve the problem mentioned in the background art: in actual operation and maintenance, the disassembly and installation of filter elements requires the use of tools to operate each filter element individually, which is a cumbersome process. Workers must tighten and loosen each filter element one by one, which not only consumes a lot of time, but is also prone to human error, leading to filter element damage or improper installation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vacuum automatic feeding device includes a dust collection box containing a filter device. The filter device includes a mounting plate with two rows of filter elements mounted on it. The mounting plate has through holes, and each filter element has a snap-fit ​​part that passes through the through holes. The snap-fit ​​part has a snap-fit ​​groove. A limiting device is mounted on the mounting plate, and the limiting device includes two movable main snap-fit ​​plates. The two main snap-fit ​​plates are snapped into the snap-fit ​​groove to maintain the stability of the filter elements.

[0006] Preferably, the card slot is annular, and the main card plate has an arc-shaped portion that engages with the annular card slot.

[0007] Preferably, the outer side of the arc-shaped portion has an auxiliary portion, which contacts the arc-shaped portion on the upper side of the slot.

[0008] Preferably, the snap-fit ​​portion has a stabilizing portion adapted to the through hole.

[0009] Preferably, a connecting strip is fixed on the main plate, one end of the connecting strip is threaded to a limit rod, and a protrusion is fixed on the mounting plate, with a limit groove formed on the protrusion.

[0010] Preferably, two auxiliary clamping plates are provided between the two rows of filter elements, and the auxiliary clamping plates have the same structure as the main clamping plates.

[0011] Preferably, both connecting strips are connected to auxiliary plates on another row of filter elements by extension, and a synchronization element is provided between the main plate and the auxiliary plate.

[0012] Preferably, the synchronizing element includes a toothed toothed strip fixed to the opposite sides of the two connecting strips, and a gear is rotatably connected to the mounting plate.

[0013] Preferably, the dust collection box is fixed to the frame, and a suction head and an air outlet pipe are connected to the dust collection box. The air outlet pipe is located above the suction head, and the filter device is located between the suction head and the air outlet pipe. A vacuum pump is installed on the frame, and one end of the air outlet pipe is connected to the air inlet of the vacuum pump. The vacuum pump is provided with an exhaust port, and an air storage tank is fixed on the dust collection box. The air storage tank is connected to the top of the dust collection box through a pipe.

[0014] Preferably, the frame is provided with a collection box for collecting dust particles.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By using a synchronizing component to achieve synchronized operation of the main and auxiliary card plates, multiple filter elements can be installed or removed simultaneously. Compared with the traditional method of disassembling and assembling one by one, this significantly shortens maintenance time, improves equipment operation and maintenance efficiency, and reduces production downtime.

[0017] Simply rotating the limit rod and moving the card plate are all it takes to fix and release the filter element, reducing the difficulty of operation for workers. No complicated tools or advanced skills are required, making it easy to maintain daily and reducing labor costs and the risk of operational errors.

[0018] The arc-shaped part and auxiliary part of the limiting device work together to enhance the longitudinal stability of the filter element; the design of the limiting rod and the limiting groove ensures the stability of the limiting device itself, making the filter element less prone to loosening after installation and improving the overall reliability of the device.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] Please see Figure 1 - Figure 8 The vacuum automatic feeding device includes a dust collection box 1, which is fixed to a frame 2. A suction head 3 and an exhaust pipe 4 are connected to the dust collection box 1, with the exhaust pipe 4 located above the suction head 3. A filter device 8 is installed inside the dust collection box 1, positioned between the suction head 3 and the exhaust pipe 4. A vacuum pump 5 is mounted on the frame 2, with one end of the exhaust pipe 4 connected to the inlet of the vacuum pump 5. The vacuum pump 5 has an exhaust port 51. An air storage tank 6 is fixed to the dust collection box 1, connected to the top of the dust collection box 1 via a pipe. A collection box 7 for collecting dust particles is installed on the frame 2. The dust collection box 1 has an outlet on its downward side. Dust enters the collection box 7 by opening and closing a valve. The dust cleaning process involves injecting high-pressure air into the dust collection box 1 through the air storage tank 6. The high-pressure air enters the dust collection box 1 and, through impact, causes the particles previously adsorbed on the filter element 82 to fall off. The use of the air storage tank 6 and the collection box 7 are existing technologies and will not be described in detail. The dust collection box 1 has a cover on top. After removing the cover, the filter device 8 can be taken out. This is existing technology.

[0034] Vacuum pump 5 provides power, suction head 3 can be connected to suction pipe, suction pipe is connected to vacuum hopper, high pressure gas enters dust collection box 1 from suction head 3. Gas enters dust collection box 1 from suction head 3, then enters vacuum pump 5 from exhaust pipe 4, and gas is discharged from exhaust port 51.

[0035] The filter device 8 includes a mounting plate 81, which is fixed inside the dust collection box 1. This is the prior art. Two rows of filter elements 82 are installed on the mounting plate 81. Gas can only enter the upper side of the mounting plate 81 after passing through the filter elements 82, and then enter the outlet pipe 4. The mounting plate 81 has a through hole 811, which is circular. The filter element 82 is connected to a snap-fit ​​part 84 that passes through the through hole 811. The snap-fit ​​part 84 is a round rod and has a stabilizing part 841 that is adapted to the through hole 811. The snap-fit ​​part 84 has a snap-fit ​​groove 842, which is annular.

[0036] The limiting device 9 is mounted on the mounting plate 81. The limiting device 9 includes two movable main clamping plates 91, which maintain the stability of the filter element 82 by clamping onto the clamping groove 842. The main clamping plates 91 have arc-shaped portions 92 that clamp onto the annular clamping groove 842. The arc-shaped portions 92 clamp onto the clamping groove 842 to fix the filter element 82 longitudinally. The outer side of the arc-shaped portions 92 has auxiliary portions 93, which contact the arc-shaped portions 92 on the upper side of the clamping groove 842, further maintaining the stability of the filter element 82.

[0037] A connecting strip 94 is fixed on the main clamping plate 91. One end of the connecting strip 94 is threaded to a limit rod 95. A protrusion is fixed on the mounting plate 81. A limit groove 83 is opened on the protrusion. The filter element 82 can be quickly fixed through the main clamping plate 91, which facilitates the installation and removal of the filter element 82.

[0038] Two auxiliary clamping plates 96 are arranged between the two rows of filter elements 82. These two auxiliary clamping plates 96 are located between the two main clamping plates 91, and their structures are identical to those of the main clamping plates 91. Each auxiliary clamping plate 96 forms a pair with its corresponding main clamping plate 91. The two rows of filter elements 82 each have an auxiliary clamping plate 96 and a main clamping plate 91 on both sides. One main clamping plate 91 and one auxiliary clamping plate 96 form a clamping mechanism to fix the two rows of filter elements 82 in place. A slide rail 98 is fixed to the mounting plate 81, and both the main clamping plates 91 and the auxiliary clamping plates 96 are slidably connected to the slide rail 98.

[0039] like Figure 5 As shown, both connecting strips 94 are extended to auxiliary clamping plates 96 on another row of filter elements 82. A synchronizing element 97 is provided between the main clamping plate 91 and the auxiliary clamping plate 96. The synchronizing element 97 includes toothed teeth 971 fixed to the opposite sides of the two connecting strips 94. A gear 972 is rotatably connected to the mounting plate 81. The gear 972 meshes with the two toothed teeth 971. The synchronizing element 97 enables the two main clamping plates 91 and the auxiliary clamping plate 96 to move simultaneously, making it easier to install and remove the filter elements 82. Traditional filter element 82 installation and removal may require individual operation and the use of complex tools, which is time-consuming and labor-intensive. This device, through the synchronizing element 97 and other structures, can achieve simultaneous installation and removal of multiple filter elements 82, significantly shortening maintenance time.

[0040] When disassembling filter element 82, first remove the filter device 8 from the dust collection box 1. First, rotate the limiting rod 95 to separate it from the limiting groove 83. Then, move it away from the center of the mounting plate 81. The limiting rod 95 moves along with the connecting strip 94, which in turn moves the main clamping plate 91 and the auxiliary clamping plate 96. Simultaneously, the toothed rack 971 and gear 972 move the other main clamping plate 91 and auxiliary clamping plate 96, causing all the arc-shaped parts 92 to simultaneously leave the slot 842. Finally, move the mounting plate 81 upwards to complete the simultaneous disassembly of filter element 82. During installation, pass the clamping part 84 of filter element 82 through the through hole 811 until the filter element 82 contacts the bottom of the mounting plate 81. By operating the limiting rod 95 or the connecting strip 94, the synchronizing element 97 moves the main and auxiliary clamping plates synchronously, causing the arc-shaped parts 92 to engage in the slot 842, thus achieving longitudinal fixation of the filter element 82. Finally, rotate the limiting rod 95 to move it down into the limiting groove 83, keeping the limiting device 9 stable, and the installation is complete.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
