Description

A vacuum feeder for granular materials that is easy to collect and clean. Technical Field

[0001] This utility model relates to a gas extraction system, specifically a vacuum feeder for particulate materials that is convenient for dust collection and cleaning. Background Technology

[0002] Plastic granules are formed into plastic products through processes such as foaming, injection molding, extrusion molding, and blow molding. Before forming the plastic products, the granules contain a significant amount of dust, which usually needs to be removed during material suction to improve the quality of the plastic products. Currently, patent CN220033343U discloses an automatic vacuum material suction machine for granular materials. Its structure includes a support frame, a power distribution cabinet, a control panel, and a main body. The power distribution cabinet is located on the top surface of the support frame, and the control panel is connected to the front surface of the power distribution cabinet. The main body is connected to the support frame. The support frame includes a frame, an air pump, a filter block, and an air pipe. The top of the frame is connected to the power distribution cabinet, the air pump is installed inside the bottom of the frame, the filter block is connected to the top of the air pump, one end of the air pipe is connected to the top surface of the filter block, and the other end of the air pipe is connected to the top of the main body. The main body includes a mounting base, support rods, and a suction device. Four support rods are located on the top of the mounting base and are arranged around the top side of the mounting base.

[0003] The aforementioned patent primarily relies on a filter screen in the suction device to filter dust that enters the vacuum hopper along with the particulate material. A secondary filter element inside the filter block at the top of the air pump further filters the fine dust in the airflow, preventing dust from entering the air pump itself. However, this patent relies solely on the filter screen and element for dust removal, and these elements lack the capacity to collect large amounts of dust. This necessitates frequent removal of the filter screen and element for cleaning; otherwise, if they accumulate too much dust, the dust in the particulate material cannot be properly removed. Summary of the Invention

[0004] This utility model discloses a vacuum feeder for granular materials that is convenient for dust collection and cleaning. Its main purpose is to overcome the problem that existing vacuum feeders do not have the function of collecting a large amount of dust, which causes the filter screen and filter element to be frequently removed for dust removal.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A vacuum feeder for granular materials, facilitating dust collection and cleaning, includes a support frame, an air pump, a dust collection device, and a hopper device. The air pump is located at the bottom of the support frame, which has a vacuum channel. The air pump's intake port is connected to the vacuum channel. The dust collection device includes a dust collection bin and a lid detachably connected to the top of the dust collection bin. The lid is connected to the top of the support frame. The lid has a spiral channel communicating with the dust collection bin. The lid also has a vertically penetrating intake channel communicating with the vacuum channel. A detachable filter cartridge is located at the bottom of the lid and inside the dust collection bin. The outlet end of the spiral channel is located outside the filter cartridge. The inlet end of the spiral channel is connected to the top interior of the hopper device. The top of the hopper device has a filter screen for dust to pass through. The hopper device is connected to a bin containing granular materials. A controller is located at one end of the top of the support frame, and the air pump is connected to the controller.

[0007] Furthermore, the support includes a base plate, a vertical tube, and a horizontal tube. The air pump is connected to the top surface of the base plate, the bottom of the vertical tube is connected to the top surface of the base plate, the horizontal tube is connected to one side of the top of the vertical tube, the interior of the horizontal tube and the interior of the vertical tube form the vacuum passage, the barrel lid is connected to the bottom of the horizontal tube, and the controller is connected to one end of the horizontal tube.

[0008] Furthermore, a connecting bracket is connected inside the air intake channel, and a connecting tube is provided at the top of the connecting bracket. The upper part of the connecting bracket is located inside the horizontal tube, and the top of the connecting tube extends out of the top surface of the horizontal tube. The connecting tube runs through the vertical direction and is fixedly connected to the horizontal tube. A top cover is provided on the top of the connecting tube.

[0009] Furthermore, the bottom of the connecting bracket is provided with a screw rod, which passes through the filter element cylinder, and the bottom surface of the filter element cylinder is provided with a tightening nut that is threaded with the screw rod.

[0010] Furthermore, the top of the dust collection bin and the bottom of the bin lid are connected by a hoop.

[0011] Furthermore, the hopper device includes a mounting base, a feed cylinder, a cylinder cover, and a vacuum hopper. The mounting base and the cylinder cover are connected by multiple connecting rods. The feed cylinder is connected between the mounting base and the cylinder cover. The vacuum hopper is connected to the top of the cylinder cover. The vacuum hopper, cylinder cover, feed cylinder, and mounting base are connected sequentially from top to bottom. The top of the vacuum hopper is provided with a detachable hopper cover. The filter screen is located inside the top of the vacuum hopper. The top of the cylinder cover is provided with an openable and closable sealing plate.

[0012] Furthermore, the top of the hopper cover is provided with a first suction pipe that communicates with the vacuum hopper, and a second suction pipe is connected between the first suction pipe and the inlet end of the spiral channel. The side of the vacuum hopper is provided with a suction pipe that communicates with the vacuum hopper and the material barrel.

[0013] Furthermore, the vacuum hopper has a support edge on its top inner circumference, the filter screen is placed on the support edge, and the hopper cover is connected to the vacuum hopper by multiple latches.

[0014] Furthermore, the side of the barrel cover is provided with an installation box, which contains a limit switch, an eccentric block, and a counterweight.

The limit switch is connected to the controller.

[0015] As described above, compared with the prior art, this utility model has the following advantages: When the air pump starts working to suck up material, the granular material in the hopper is sucked into the hopper device. As the granular material enters the hopper device, the dust is sucked into the dust collection bin after passing through the filter screen. Because the lid of the bin is provided with a spiral channel, when the dust passes through the spiral channel, it will rotate and collect at the bottom of the dust collection bin. The filter cartridge in the dust collection bin can prevent the dust in the dust collection bin from entering the air pump through the vacuum channel, thus avoiding damage to the air pump. In this utility model, the dust collection bin can collect a large amount of dust. When there is a lot of dust in the dust collection bin, the dust collection bin can be removed and the dust inside can be cleaned. Compared with the existing vacuum suction machine, this utility model can concentrate the dust, avoiding all the dust from being concentrated on the filter screen and filter cartridge, thereby reducing the number of times the filter screen and filter cartridge need to be removed for dust removal, and further improving production efficiency.

[0028] Referring to Figures 1, 4, and 5, the hopper device 4 includes a mounting base 42, a feed cylinder 43, a cylinder cover 44, and a vacuum hopper 45. The mounting base 42 and the cylinder cover 44 are connected by four connecting rods 46. The feed cylinder 43 is connected between the mounting base 42 and the cylinder cover 44. The vacuum hopper 45 is connected to the top of the cylinder cover 44. The vacuum hopper 45, cylinder cover 44, feed cylinder 43, and mounting base 42 are connected sequentially from top to bottom. The top of the vacuum hopper 45 is provided with a detachable hopper cover 47. The filter screen 41 is located inside the top of the vacuum hopper 45. The top of the cylinder cover 44 is provided with an openable and closable sealing plate 48.

[0029] Referring to Figures 1, 4, and 5, the top of the hopper cover 47 is provided with a first suction pipe 471 communicating with the vacuum hopper 45. A second suction pipe 7 is connected between the first suction pipe 471 and the inlet end of the spiral channel 33. The side of the vacuum hopper 45 is provided with a suction pipe 451 communicating with the vacuum hopper 45 and the material bucket 5. The inner circumference of the top of the vacuum hopper 45 is provided with a support edge 452, and the filter screen 41 is placed on the support edge 452. The hopper cover 47 is connected to the vacuum hopper 45 by four latches 49. The latches 49 are existing structures, and their specific structure will not be described in detail here. The latches 49 can be fastened and opened. When the latches 49 are fastened, the hopper cover 47 and the vacuum hopper 45 are connected. When the latches 49 are opened, the hopper cover 47 can be removed from the vacuum hopper 45. When the hopper cover 47 is removed, the filter screen 41 can be taken out for dust cleaning.

[0030] Referring to Figures 1, 4, and 5, a mounting box 8 is provided on the side of the material cylinder cover 44. The mounting box 8 contains a limit switch 81, an eccentric block 82, and a counterweight 83. A rotating shaft 9 is connected to one side of the sealing plate 48. The rotating shaft 9 is located inside the material cylinder cover 44 and is rotatably connected to the material cylinder cover 44. One end of the rotating shaft 9 passes through the mounting box 8 and is eccentrically connected to the eccentric block 82. A connecting block 91 is connected to the other end of the rotating shaft 9. The connecting block 91 is connected to the counterweight 83 through a connecting rod 92. The eccentric block 82 is located between the limit switch 81 and the counterweight 83. The limit switch 81 is connected to the controller 6. When the weight of the granular material in the vacuum hopper 45 is less than the weight of the counterweight 83, the counterweight 83 is in a downward pressing state, causing the sealing plate 48 to block the bottom of the vacuum hopper 45, preventing the vacuum hopper 45 from discharging material. When the weight of the granular material in the vacuum hopper 45 is greater than the weight of the counterweight 83, the granular material in the vacuum hopper 45 will drive the sealing plate 48 and the rotating shaft 9 to rotate, causing the counterweight 83 to tilt upward. At the same time, the eccentric block 82 rotates and abuts against the limit switch 81, causing the switch contacts of the limit switch 81 to close. A signal is sent to the controller 6, which then controls the air pump 2 to stop working. After the sealing plate 48 rotates and opens, the vacuum hopper 45 begins to discharge material. After the vacuum hopper 45 finishes discharging material, under the action of the counterweight 83, the counterweight 83 is back in a downward pressing state, the sealing plate 48 blocks the bottom of the vacuum hopper 45 again, and at the same time, the eccentric block 82 rotates and resets, releasing its contact with the limit switch 81. If the controller 6 does not receive a signal from the limit switch 81, it restarts the air pump 2 to suck up material.

[0031] Referring to Figures 1 to 4, the design principle of this utility model is as follows: When the controller 6 controls the air pump 2 to start working and suck up materials, the granular material in the material bucket 5 is sucked into the vacuum hopper 45. Blocked by the filter screen 41, the granular material can only remain in the vacuum hopper 45. As the granular material enters the vacuum hopper 45, the dust is sucked into the dust collection bucket 31 after passing through the filter screen 41. Since the bucket lid 32 has a spiral channel 33, when the dust passes through the spiral channel 33, it will rotate and collect at the bottom of the dust collection bucket 31. The filter cartridge 35 inside the dust collection bucket 31 can prevent the dust in the dust collection bucket 31 from entering the air pump 2 through the vacuum passage 10, thus avoiding damage to the air pump 2. The dust collection bucket 31 can collect a large amount of dust. When a large amount of dust accumulates in the dust collection bucket 31, the dust collection bucket 31 can be removed for cleaning. When the filter cartridge 35 accumulates a large amount of dust, the top cover 38 can be opened, and an air gun can be inserted through the connecting pipe 37 to spray air onto the filter cartridge 35, thereby spraying the dust on the filter cartridge 35 into the dust collection bin 31. When the filter cartridge 35 needs to be replaced or cleaned, it can also be removed after the dust collection bin 31 is removed for replacement or cleaning. When the filter screen 41 accumulates a lot of dust, the latch 49 can be opened, and then the hopper cover 47 can be removed from the vacuum hopper 45. At this time, the filter screen 41 can be taken out for dust removal and cleaning. In this embodiment, the dust collection bin 31 is made of transparent material, which facilitates observation of the dust accumulation inside the dust collection bin 31.

[0032] Referring to Figures 1, 2, and 4, the dust collection bin 31 of this invention can collect a large amount of dust. When there is a lot of dust in the dust collection bin 31, the dust collection bin 31 can be removed and the dust inside can be cleaned. Compared with the existing vacuum suction machine, this invention can concentrate the dust, avoiding the dust from being concentrated on the filter screen 41 and filter cartridge 35, thereby reducing the number of times the filter screen 41 and filter cartridge 35 need to be removed for dust removal, and further improving production efficiency.

[0033] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
