Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum feeders, and in particular relates to an anti-blocking vacuum feeder. Background Art

[0002] A vacuum loader, also known as a vacuum conveyor, is a dust-free, enclosed pipeline conveying device that uses vacuum suction to transport granular and powdered materials. The pressure difference between the vacuum and the surrounding air creates air flow within the pipeline, driving the movement of the powdered material and thus completing the powder conveying process. Vacuum loaders are widely used in light and heavy industries such as the chemical, pharmaceutical, food, metallurgy, building materials, and agricultural by-products industries. They are primarily used to convey powdered and granular materials, such as API powders, chemical powders, metal oxide powders, capsules, tablets, pills, and small food granules. They are not suitable for conveying overly wet, sticky, or heavy materials.

[0003] Problems with existing technologies:

[0004] During the use of the vacuum loader in the prior art, the filter plate separating the internal vacuum equipment and the suction channel is prone to blockage when conveying powder or powdered materials, requiring shutdown for cleaning or replacement, which seriously affects production efficiency. The main reason for the blockage of the respirator of the vacuum loader is that the loading time of the vacuum loader is set too long, and the discharge time and backflush time are set unreasonably, which makes blockage easy to occur.

Two rubber beating plates for beating the filter plates are arranged between the two filter plates. The two rubber beating plates are symmetrically arranged on the swinging shaft.

[0010] The above-mentioned anti-blocking vacuum loader is adopted, and the controller controls the electric push rod on the replacement mechanism to extend or retract, so that the electric push rod drives the linkage plate to move synchronously, and at the same time drives the upper sleeve slide plate to move synchronously, thereby driving the upper push-pull shaft and the sliding sleeve to slide along the rotating shaft, so that the sliding sleeve can drive the rotating shaft to rotate by relying on the rotating shaft, so that the rotating shaft drives the sliding sleeve and the sleeve slide plate on the lower side to move in the opposite direction of the upper sleeve slide plate, so that the two oppositely moving sleeve slide plates drive the two filter plates to move synchronously, so that the filter plate corresponding to the conveying pipe can slide to one side along the dividing plate, and at the same time the other filter plate slides to the corresponding conveying pipe and is squeezed into contact with the rubber back plate, thereby completing the replacement operation of the two filter plates;

[0011] Then the controller controls the driving click on the beating mechanism to start, and the driving motor drives the connecting shaft and the active bevel gear to rotate, and the active bevel gear engages to drive the driven bevel gear and the swing shaft to rotate, and the rotating swing shaft drives the two rubber beating plates to rotate to beat the replaced filter plate, so that the impurities filtered and intercepted on the filter plate are shaken off and then collected through the collection frame.

[0017] Preferably, the vacuum loader body and the buffer tank are both arranged on a base, and universal wheels are provided at the four corners of the bottom surface of the base.

[0018] The beneficial effects are:

[0019] The utility model drives the linkage plate and the sliding plate to move through the electric push rod on the replacement mechanism, and drives the rotation shaft to rotate, thereby driving the two filter frames to move relative to each other, so that the two filter plates are replaced. In this way, the swinging shaft on the flapping mechanism can be driven by the driving motor to rotate the two rubber flapping plates to flap the filter plates, so that the filter plates are flapped to produce vibrations, and the filtered and intercepted impurities fall off into the collection frame. In this way, the vacuum loader body can replace the filter plates during the suction time, thereby ensuring that the suction is maintained normally when the suction time is too long, which can improve the suction efficiency and the use effect.

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, a vacuum feeder for preventing blocking materials includes a filter frame 1 and a replacement mechanism 2 and a flapping mechanism 3 provided on the filter frame 1. The flapping mechanism 3 is connected to the replacement mechanism 2 via two rubber flapping plates 302. The filter frame 1 is provided on the upper side of the vacuum feeder body 4. The filter frame 1 is interconnected with a buffer tank 8 via a conveying pipe 9 provided therebetween.

[0028] The replacement mechanism 2 includes two filter plates 201, both of which are arranged in the filter frame 1. A partition plate is provided in the filter frame 1. The two filter frames 1 are staggered and sleeved on the partition plate 12 on both sides thereof. Two sets of slide grooves 11 are provided in the filter frame 1 for limiting the sliding direction of the filter frame 1. Two sets of rubber extrusion sealing plates 202 are provided on both sides of the partition plate 12. When the filter plates 201 come into contact with the partition plate 12, a sealing effect is formed by squeezing the sealing plates 202. The two sets of extrusion sealing plates 202 are provided on both sides of the filter frame 1.

[0029] The beating mechanism 3 includes a swinging shaft 301, which is rotatably set on the filter frame 1 and the dividing plate 12. The swinging shaft 301 is located between the filter plates 201. Two rubber beating plates 302 are provided between the two filter plates 201 to beat the filter plates 201. The two rubber beating plates 302 are symmetrically set on the swinging shaft 301.

[0030] As an optional embodiment, two sleeve slides 203 are provided on the filter frame 1, and two sliding sleeves 208 are provided on the side of the filter frame 1. The two sliding sleeves 208 are respectively rotatably cooperated with the two push-pull shafts 204. The two push-pull shafts 204 are respectively fixedly connected to one side of the two sleeve slides 203, and the other sides of the two sleeve slides 203 are respectively fixedly connected to the side surfaces of the two filter frames 1. With such an arrangement, the sleeve 208 can slide on the rotating shaft 207, so that the rotating shaft 207 can be rotated by relying on the drive of the electric push rod 210, so that the two sleeves 208 can be driven to rotate and slide, thereby driving the two sleeve slides 203 to move in opposite directions.

[0031] Refer to the attached Figure 3 A fixed plate 205 and a rotating shaft 207 are fixed to the side of the filter frame 1. A rotating shaft 206 is rotatably provided on the fixed plate 205 away from the filter frame 1. The free end of the rotating shaft 206 is fixedly connected to the middle of the rotating shaft 207. Two sliding sleeves 208 are respectively sleeved on both sides of the rotating shaft 207. Such a setting allows the rotating shaft 207 to rely on the rotation support of the rotating shaft 206, so that the two sliding sleeves 208 on the rotating shaft 207 rotate and slide at the same time, thereby driving the sleeve slide plate 203 to move.

[0032] Furthermore, an electric push rod 210 is installed on the side of the filter frame 1, and the protruding end of the electric push rod 210 is fixedly connected to one side of the linkage plate 209, and the other side of the linkage plate 209 is fixedly connected to the upper sliding plate 203. With this arrangement, the two filter plates 201 can be driven to move and replace each other by relying on the telescopic adjustment of the electric push rod 210, thereby improving the level of automation.

[0033] Refer to the attached Figure 4 The filter frame 1 is provided with a driven bevel gear 303 and a connecting shaft 305 on the side surface of the filter frame 1. The driven bevel gear 303 is arranged on the free end of the swing shaft 301, and one end of the connecting shaft 305 is provided with a driving bevel gear 304. The driving bevel gear 304 is meshed with the driven bevel gear 303. A driving motor 306 is installed on the side of the filter frame 1, and the output shaft of the driving motor 306 is connected to the other end of the connecting shaft 305. A stable shaft plate 307 is fixed on the side of the filter frame 1, and the stable shaft plate 307 rotates in coordination with the connecting shaft 305. With such an arrangement, the swing shaft 301 can be indirectly driven to rotate by the driving motor 306, thereby driving the rubber flapping plate 302 to rotate cyclically to flap the filter plate 201, thereby improving the flapping and shaking effect on the filter plate 201.

[0034] Furthermore, a rubber back plate 10 is provided on the side opposite to the two filter plates 201 inside the filter frame 1, and a collecting frame 7 is provided on the filter frame 1. The collecting frame 7 corresponds to the rubber slapping plate 302 up and down, which can facilitate the collection of impurities shaken off the filter plates 201. The rotation radius of the rubber slapping plate 302 is greater than the distance between the swing shaft 301 and the filter plate 201, so that the swing shaft 301 can drive the rubber slapping plate 302 to slap and contact the filter plate 201 when it rotates.

[0035] Furthermore, the vacuum loader body 4 and the buffer tank 8 are both arranged on the base 5, and universal wheels are provided at the four corners of the bottom surface of the base 5 to facilitate the movement of the device. A controller 6 is installed on the side of the vacuum loader body 4, and the output end of the controller 6 is electrically connected to the input end of the electric push rod 210 and the drive motor 306.

[0036] By adopting the above structure, the controller 6 controls the electric push rod 210 on the replacement mechanism 2 to extend or retract, so that the electric push rod 210 drives the linkage plate 209 to move synchronously, and at the same time drives the upper sleeve slide plate 203 to move synchronously, thereby driving the upper push-pull shaft 204 and the sliding sleeve 208 to slide along the rotating shaft 207, so that the sliding sleeve 208 can drive the rotating shaft 207 to rotate by relying on the rotating shaft 206, so that the rotating shaft 207 drives the sliding sleeve 208 and the sleeve slide plate 203 on the lower side to move in the opposite direction to the upper sleeve slide plate 203, so that the two oppositely moving sleeve slide plates 203 drive the two filter plates 201 to move synchronously, so that the filter plate 201 corresponding to the conveying pipe 9 can slide to one side along the dividing plate 12, and at the same time, the other filter plate 201 slides to the corresponding conveying pipe 9 and is squeezed into contact with the rubber backing plate 10, thereby completing the replacement operation of the two filter plates 201;

[0037] Then, the controller 6 controls the driving click on the beating mechanism 3 to start, and the driving motor 306 drives the connecting shaft 305 and the active bevel gear 304 to rotate. The active bevel gear 304 engages to drive the driven bevel gear 303 and the swing shaft 301 to rotate. The rotating swing shaft 301 drives the two rubber beating plates 302 to rotate and beat the replaced filter plate 201, so that the impurities filtered and intercepted on the filter plate 201 are shaken off and then collected by the collection frame 7.

[0038] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
