Description

Technical Field

[0001] This utility model relates to the field of vacuum feeder technology, and in particular to a vacuum feeder with a cleaning function. Background Technology

[0002] Vacuum conveyors, also known as vacuum feeders, are dust-free, closed-loop conveying equipment that uses vacuum suction to transport granular and powdery materials. They utilize the pressure difference between the vacuum and the ambient space to create gas flow within the pipe, which in turn moves the powdery materials, thus completing the conveying of the powder.

[0003] According to the authorization announcement number: CN221543300U, an automatic cleaning device for a vacuum feeder is disclosed, which relates to the field of vacuum feeder technology. Its beneficial effects are as follows: the cooperation between the hollow tube frame and the solenoid valve facilitates the rinsing of materials with high viscosity; the cooperation between the sleeve and the suction pipe allows the fixing block to be inserted into the fixing groove during suction to prevent the suction pipe from rotating and affecting the suction efficiency; during backflushing, the fixing block is disengaged from the fixing groove; and the design of the spiral blade drives the suction pipe to rotate, so that the sprayed gas can more thoroughly clean the filter pipe and the inside of the feeder body.

[0004] While the above technology facilitates the cleaning of residues on the inner wall of the feeding machine, it still has shortcomings: 1. The moisture after cleaning is easily absorbed by the inner wall of the feeder, causing the material to become damp and clump together, leading to material blockage and reducing conveying efficiency. In addition, the humid environment is prone to bacterial growth, which poses a certain risk to industries with high hygiene requirements (such as pharmaceuticals and food). Second: After cleaning, the vacuum feeder needs to be disassembled by staff for natural air drying or external drying, which prolongs downtime and reduces production efficiency.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1: Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a vacuum feeder with a cleaning function, including a feeder body 1, a sealing cover 2 on the top of the feeder body 1, a discharge chamber 3 on the bottom of the feeder body 1, a cleaning component 4 and a drying component 5 respectively on the inner wall of the feeder body 1, and a connecting component 6 on the outer side of the feeder body 1. The drying assembly 5 includes a hot air blower 51 fixed to one side of the feeder body 1 via a positioning plate. A connecting pipe 52 is connected to one side of the feeder body 1. The air outlet of the hot air blower 51 is connected to one end of the connecting pipe 52 via a flange. An annular groove 53 is provided on the inner wall of the feeder body 1. Multiple sets of air outlets 54 and drainage grooves 55 are respectively provided on the inner wall of the annular groove 53. One end of the connecting pipe 52 is connected to the inner wall of the annular groove 53.

[0027] The model number of the hot air blower 51 is SHD-9F.

[0028] Multiple sets of annular grooves 53, air outlets 54 and drainage grooves 55 are all connected, and multiple sets of drainage grooves 55 extend downward and are close to the bottom of the feeder body 1.

[0029] After the material is conveyed, the cleaning component 4 is started to rinse the inner wall of the feeder body 1. Then, the hot air blower 51 is started to deliver hot air to the annular groove 53 through the connecting pipe 52. The hot air flows into the feeder body 1 through multiple air outlets 54 through the annular groove 53 to dry the residual moisture on its inner wall. The water flowing into the annular groove 53 can be returned to the feeder body 1 through the drainage groove 55 to prevent it from entering the hot air blower 51.

[0030] The device includes a feeding machine body 1, a sealing cover 2 on the top of the feeding machine body 1, a discharge hopper 3 at the bottom of the feeding machine body 1, a cleaning component 4 and a drying component 5 on the inner wall of the feeding machine body 1, a connecting component 6 on the outer side of the feeding machine body 1, an exhaust pipe connected to one side of the top of the sealing cover 2, and a PLC controller on the other side of the top of the sealing cover 2. The PLC controller model is S7-200.

[0031] The drying assembly 5 includes a hot air blower 51 fixed to one side of the feeder body 1 via a positioning plate. A connecting pipe 52 is connected to one side of the feeder body 1. The air outlet of the hot air blower 51 is connected to one end of the connecting pipe 52 via a flange. An annular groove 53 is provided on the inner wall of the feeder body 1. An air guide pipe 54 is provided on the inner wall of the annular groove 53. A pneumatic rotary joint 55 is provided on the outer side of the air guide pipe 54. A guide plate 56 is fixedly connected to the inner wall of the air guide pipe 54. One end of the pneumatic rotary joint 55 is connected to a jet pipe 57. A humidity sensor 58 is provided on the inner wall of the feeder body 1. Multiple sets of jet holes are provided on the outer side of the jet pipe 57.

[0032] The jet pipe 57 is arranged vertically. The bottom of the jet pipe 57, which is located below the air guide pipe 54, has a drain hole. The rinsing water of the cleaning component 4 enters the air guide pipe 54 through part of the jet hole and is finally discharged through the drain hole.

[0033] The hot air blower model 51 is: SHD-9F.

[0034] The humidity sensor model 58 is DHT11.

[0035] The hot air blower 51 and the humidity sensor 58 are electrically connected to the PLC controller.

[0036] The guide plate 56 is positioned directly opposite the connecting pipe 52, and both sides of the guide plate 56 are arc-shaped.

[0037] The hot air blower 51 is fixed to the side of the feeding machine body 1 by a positioning plate, and its air outlet is sealed and connected to the connecting pipe 52 through a flange. During operation, the hot air blower 51 starts, delivering heated air (hot air) through the connecting pipe 52 to a pre-set annular groove 53 inside the loading machine body 1. An air guide pipe 54 is installed on one side of the annular groove 53, and a guide plate 56 is fixed inside the air guide pipe 54. Its function is to guide the airflow direction, ensuring that the hot air can flow efficiently and stably to the jet pipe 57. When the air passes through the pneumatic rotary joint 55, the air pressure from the air source acts on the pneumatic components inside the pneumatic rotary joint 55. The pneumatic components generate thrust, which is transmitted to the internal spiral mechanism, converting the thrust into rotational torque, thereby driving the jet pipe 57 to rotate. This evenly blows the hot air into the loading machine body 1, achieving all-round, dead-angle-free drying. During the drying process, the humidity sensor 58 monitors the humidity environment parameters inside the feeding machine body 1 in real time. When the humidity inside the feeding machine body 1 reaches the preset value (usually around 40%), the signal is transmitted to the PLC controller. The PLC controller controls the hot air fan 51 to automatically shut down according to the preset humidity threshold, so as to avoid over-drying, reduce operating costs, and save energy.

[0038] The feeding machine body 1 includes a feed pipe 101, a filter screen 102, a discharge hopper 103 and a solenoid valve 104. The feed pipe 101 is connected to one side of the feeding machine body 1, and the filter screen 102 is provided on the inner wall of the feeding machine body 1.

[0039] The feed pipe 101 is connected to an external storage device, and the filter screen 102 is used to intercept the material.

[0040] The bottom of the feeding machine body 1 is connected to the feeding hopper 103. A solenoid valve 104 is provided on the outside of the feeding hopper 103. Opening the solenoid valve 104 allows the material in the feeding machine body 1 to enter the discharge bin 3 from the feeding hopper 103.

[0041] The sealing cover 2 includes a vacuum pump 21 and a suction pipe 22. The top of the sealing cover 2 is fixedly connected to the vacuum pump 21 by screws. The suction end of the vacuum pump 21 is connected to the suction pipe 22. The bottom end of the suction pipe 22 extends to the bottom of the sealing cover 2.

[0042] Start the vacuum pump 21 to draw air into the feeder body 1 through the air extraction pipe 22, so that a negative pressure is formed inside the feeder body 1. At this time, the material enters the feeder body 1 through the feed pipe 101.

[0043] The discharge bin 3 includes a connecting plate 31, a connecting shaft 32, and a diverter plate 33. The connecting plate 31 is fixedly connected to the inner wall of the discharge bin 3.

[0044] A connecting shaft 32 is fixedly connected to the top of the connecting plate 31, and a diverter plate 33 is rotatably connected to the top of the connecting shaft 32. Multiple diverter grooves are formed on the inner wall of the diverter plate 33.

[0045] Material enters the discharge bin 3 and impacts the distribution plate 33, causing the distribution plate 33 to rotate via the connecting shaft 32, thus dispersing the material.

[0046] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, the cleaning component 4 includes an annular diversion pipe 41 set on the inner wall of the feeder body 1 via a connecting block. Six sets of nozzles 42 are connected to the outer side of the annular diversion pipe 41, and a water inlet pipe 43 is connected to the top of the annular diversion pipe 41. Three sets of nozzles 42 are set vertically, and the other three sets of nozzles 42 are set at an angle. One end of the water inlet pipe 43 extends to the outer side of the feeder body 1, and the water inlet pipe 43 is connected to an external water pump.

[0048] The external water pump is started to bring water into the annular diversion pipe 41 through the inlet pipe 43, and sprays it from the six sets of nozzles 42 onto the side walls of the filter screen 102 and the feeder body 1, thereby rinsing them.

[0049] Specifically, the cleaning assembly 4 also includes a fixing plate fixed to the inner wall of the feeding machine body 1, and a fixing shaft 44 is rotatably connected to the inner wall of the fixing plate. A fan blade 45 and a brush 46 are fixedly connected to the top and bottom of the fixing shaft 44, respectively.

[0050] When the vacuum pump 21 is running, the negative pressure generated inside the feeder body 1 will drive the fan blade 45 to rotate, thereby causing the fixed shaft 44 to drive the brush 46 to rotate synchronously. The brush 46 can clean the material adsorbed on the filter screen 102.

[0051] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, the connecting assembly 6 includes a first fixing plate 61 fixed to the bottom of the sealing cover 2 and the hopper 103, and a second fixing plate 62 fixedly connected to the top of the feeding machine body 1 and the discharge bin 3. A first retaining ring 63 and a second retaining ring 64 are respectively provided on the outer sides of the two sets of first fixing plates 61 and second fixing plates 62. The first retaining ring 63 and the second retaining ring 64 are hinged together by a hinge. A connecting seat 65 is fixedly connected to the outer sides of the first retaining ring 63 and the second retaining ring 64. A bolt 66 is threadedly connected to the inner wall of the connecting seat 65.

[0053] First, move the feeding machine body 1 so that the first fixing plate 61 at the bottom of the hopper 103 fits against the second fixing plate 62 at the top of the discharge bin 3. Then, move the sealing cover 2 so that the first fixing plate 61 at its bottom fits against the second fixing plate 62 at the top of the feeding machine body 1. Finally, move the first retaining ring 63 and the second retaining ring 64 to fit on the outside of the first fixing plate 61 and the second fixing plate 62, and screw the bolt 66 into the connecting seat 65. This allows the feeding machine body 1 to be connected to the sealing cover 2 and the discharge bin 3, while also facilitating disassembly for internal maintenance.

[0054] During use, the vacuum pump 21 is started to draw air into the feeder body 1 through the suction pipe 22, creating a negative pressure inside the feeder body 1. At this time, the material enters the feeder body 1 through the feed pipe 101 and is intercepted by the filter screen 102. Under the action of negative pressure, the fan blade 45 drives the brush 46 to rotate, cleaning the material adsorbed on the filter screen 102. Then, the solenoid valve 104 is started to allow the material to enter the discharge bin 3 through the discharge hopper 103 for dispersion. Then, the external water pump is started to deliver water to the annular diversion pipe 41 and spray it from the six sets of nozzles 42 onto the filter screen 102 and the side wall of the feeder body 1 to wash away the residue. Finally, the hot air blower 51 is started to deliver hot air to the annular groove 53 through the connecting pipe 52. The hot air flows into the feeder body 1 through the annular groove 53 from multiple air outlets 54 to dry the moisture remaining on its inner wall.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
