Abstract
Description
Technical Field
[0001] This utility model relates to the field of material feeding and filtration technology, specifically a centralized material feeding system. Background Technology
[0002] During feeding, the centralized feeding system uses a vacuum feeder to extract air from the equipment, creating a negative pressure environment. This pressure difference draws material into the suction nozzle, where it is then transported to the target location via a sealed conveying pipe. Throughout this process, a filtration device separates air from material, ensuring that material does not enter the vacuum pump. When the material reaches the target location, a weighing system monitors its weight in real time. Once the preset weight is reached, the control system sends a signal to stop the vacuum pump, thus completing the material conveying and weighing process.
[0003] The existing patent publication number CN221796228U discloses a powder vacuum feeding device, which includes an outer pipe and a feeding pipe. When feeding is required, the power is turned on, and the vacuum pump or vacuum source is activated. At this time, the inside of the receiving equipment gradually becomes negative pressure, and the material enters the receiving hopper through the material pipeline from the feeding pipe. Gas and the generated feeding dust enter the vacuum tube through the gap between the outer pipe and the feeding pipe. After the dust is filtered by the filter element, the gas is finally discharged through the dust removal pipeline of the fan or vacuum source. After feeding is completed, this device needs to be removed from the receiving equipment and placed in the designated position. The receiving pipe of the receiving equipment should be sealed tightly with a quick-release blind flange. During this period, the filter element needs to be cleaned and washed regularly according to the material conditions on site to prevent pipeline blockage.
[0004] During gas filtration, although the vacuum pump feeding system performs backflushing on the filter plates, blockages can still occur. To maintain normal gas flow, the vacuum pump needs to increase its power to overcome the resistance caused by the blockage, which significantly increases the equipment's energy consumption. Therefore, regular cleaning is necessary. However, the aforementioned devices suffer from inconvenience in cleaning or replacing the filter elements. To address these issues, a centralized feeding system is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a centralized material supply system to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A centralized feeding system includes a tank, a cover plate, and a filter box installed on one side of the tank. A cavity is opened on one side of the filter box, and a plurality of filter elements are slidably connected in the cavity. Guide plates are fixedly connected to both sides of the filter elements, and a positioning component for limiting the guide plates is provided in the cavity.
[0008] The positioning component includes a limiting groove and a positioning block. The two sets of limiting grooves are respectively opened on opposite sides of the two sets of guide plates. The positioning block is slidably connected in the limiting groove. Guide grooves for sliding with the guide plates are opened on both sides of the inner wall of the cavity. The guide grooves are connected to the outside. A positioning groove for the positioning block to be engaged is opened on one side of the inner wall of the guide groove. A spring is connected to the side of the positioning block away from the positioning groove. The end of the spring away from the positioning block is connected to one side of the inner wall of the limiting groove. An adjustment element is provided on one side of the positioning block.
[0009] The cavity is provided with a snap-fit assembly for limiting the position of the filter element, and a cover plate is hinged to one side of the filter box.
[0010] In one alternative: the adjusting component includes a slide groove, which is formed on one side of the inner wall of the limiting groove, and a slider is slidably connected in the slide groove, with one side of the slider being fixedly connected to one side of the positioning block.
[0011] In one alternative embodiment: the snap-fit assembly includes a limiting plate and a limiting strip, the limiting plate being located within the cavity, the limiting strip being located between two sets of filter elements, the limiting strip being fixedly connected to one side of the limiting plate, and the limiting plate being snapped between several sets of opposing sliders.
[0012] In one alternative: both sides of the limiting plate are fixedly connected with locking blocks, and both sides of the inner wall of the cavity are provided with locking grooves for engaging the locking blocks, and the locking grooves are connected to the outside.
[0013] In one alternative: a second mounting plate is fixedly connected to the bottom of the cover plate, a first mounting plate is fixedly connected to the bottom of the filter box, the second mounting plate and the first mounting plate are connected by bolts, and a handle is provided on one side of the cover plate.
[0014] In one alternative: an air outlet duct is installed on the side of the filter box away from the tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention features a filter box, cavity, filter element, guide plate, and positioning assembly. By pressing two sets of sliders on one side of a filter element with both hands, the two sets of sliders slide within a groove, causing a positioning block to disengage from the positioning groove and compress a spring. Once the positioning block disengages from the positioning groove, it pulls the filter element outward. The filter element then causes the two sets of guide plates to slide outward within the guide groove, facilitating cleaning and replacement of the filter element. This reduces the likelihood of filter element blockage, which would otherwise require the vacuum pump to increase power to overcome resistance and thus increase energy consumption.
[0017] This utility model uses a snap-fit assembly to move the limiting plate outward. The limiting plate drives two sets of snap-fit blocks to slide outward in the slot and disengage from the slot. At the same time, it drives the limiting strip to move outward. The limiting strip can reduce the gap between the two sets of filter elements. The limiting plate is snapped between several sets of opposing sliders to limit the sliders. Attached Figure Description

[0025] 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.
[0026] Please see Figures 1-5 In this embodiment, a centralized feeding system includes a tank 11, a cover plate 13, and a filter box 12 installed on one side of the tank 11. A cavity 14 is opened on one side of the filter box 12. A plurality of filter elements 15 are slidably connected in the cavity 14. Guide plates 16 are fixedly connected to both sides of the filter elements 15. A positioning component for limiting the guide plates 16 is provided in the cavity 14.
[0027] The positioning component includes a limiting groove 20 and a positioning block 19. Two sets of limiting grooves 20 are respectively opened on opposite sides of two sets of guide plates 16. The positioning block 19 is slidably connected within the limiting groove 20. Guide grooves 17 for sliding with the guide plates 16 are opened on both sides of the inner wall of the cavity 14. The guide grooves 17 are connected to the outside. A positioning groove 18 for engaging with the positioning block 19 is opened on one side of the inner wall of the guide groove 17. A spring 22 is connected to the side of the positioning block 19 away from the positioning groove 18. One end away from the positioning block 19 is connected to one side of the inner wall of the limiting groove 20. An adjusting component is provided on one side of the positioning block 19. The adjusting component drives the positioning block 19 to disengage from the positioning groove 18 and squeezes the spring 22. After the positioning block 19 disengages from the positioning groove 18, it pulls the filter element 15 outward. The filter element 15 drives the two sets of guide plates 16 to slide outward in the guide groove 17, which makes it easier for the staff to clean and replace the filter element 15 and reduces the phenomenon of increased energy consumption caused by the vacuum pump increasing power to overcome resistance due to the clogging of the filter element 15.
[0028] The cavity 14 is provided with a snap-fit assembly for limiting the position of the filter element 15, and a cover plate 13 is hinged to one side of the filter box 12.
[0029] The adjusting component includes a slide groove 21, which is formed on one side of the inner wall of the limiting groove 20. A slider 23 is slidably connected in the slide groove 21. One side of the slider 23 is fixedly connected to one side of the positioning block 19. When two sets of sliders 23 are squeezed on one side of a filter element 15 by both hands, the two sets of sliders 23 slide in the slide groove 21, which facilitates the positioning block 19 to slide in the limiting groove 20, disengage from the positioning groove 18, and squeeze the spring 22.
[0030] The snap-fit assembly includes a limiting plate 24 and a limiting strip 25. The limiting plate 24 is located inside the cavity 14, and the limiting strip 25 is located between two sets of filter elements 15. The limiting strip 25 is fixedly connected to one side of the limiting plate 24. The limiting plate 24 is snapped between several sets of opposing sliders 23. Moving the limiting plate 24 outward causes the limiting strip 25 to move outward. The limiting strip 25 can reduce the gap between the two sets of filter elements 15. The limiting plate 24 is snapped between several sets of opposing sliders 23 to limit the sliders 23.
[0031] Both sides of the limiting plate 24 are fixedly connected with locking blocks 26. Both sides of the inner wall of the cavity 14 are provided with locking grooves 27 for engaging the locking blocks 26. The locking grooves 27 are connected to the outside. When the limiting plate 24 moves outward, the limiting plate 24 drives the two sets of locking blocks 26 to slide outward in the locking grooves 27 and disengage from the locking grooves 27, which facilitates the positioning and guidance of the movement of the limiting plate 24.
[0032] The bottom of the cover plate 13 is fixedly connected to a second mounting plate 28, and the bottom of the filter box 12 is fixedly connected to a first mounting plate 29. The second mounting plate 28 and the first mounting plate 29 are connected by bolts. A handle is provided on one side of the cover plate 13. By holding the handle and flipping the cover plate 13, the second mounting plate 28 and the first mounting plate 29 are brought close together and connected by bolts, which makes it convenient for the staff to open the filter box 12 and clean and replace the filter element 15.
[0033] The filter box 12 is equipped with an air outlet pipe on the side away from the tank 11. The air outlet pipe can be connected to a vacuum pump to facilitate the discharge of filtered air.
[0034] The working principle of this invention is as follows: After the tank 11 is started, the vacuum pump or vacuum generator begins to work, extracting the air inside the tank 11 to create a negative pressure environment. This negative pressure causes the air pressure at the suction nozzle to be lower than the surrounding environment, thereby generating a pressure difference that draws the material into the suction nozzle. After being drawn in, the material is transported to the target location through a sealed conveying pipe. During this process, the filter box 12 separates the air and the material, ensuring that the material does not enter the vacuum pump, while also ensuring that the discharged air meets environmental protection standards.
[0035] When cleaning the inside of the filter box 12, first use external tools to remove the bolts, hold the handle and flip the cover plate 13 to open the filter box 12. Move the limiting plate 24 outward. The limiting plate 24 drives the two sets of locking blocks 26 to slide outward in the locking groove 27 and disengage from the locking groove 27. At the same time, it drives the limiting strip 25 to move outward. Press the two sets of sliders 23 on one side of a filter element 15 with both hands. The two sets of sliders 23 slide in the sliding groove 21, driving the positioning block 19 to disengage from the positioning groove 18 and press the spring 22. After the positioning block 19 disengages from the positioning groove 18, it pulls the filter element 15 outward. The filter element 15 drives the two sets of guide plates 16 to slide outward in the guide groove 17, which makes it easier for the staff to clean and replace the filter element 15 and reduces the phenomenon of filter element 15 clogging, which causes the vacuum pump to increase power to overcome resistance and increase energy consumption.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
