Description

Technical Field

[0001] This invention relates to a transfer device, and more particularly to a powder docking device. Background Technology

[0002] In the process of powder handling, powder transfer is a common process. There are various traditional powder docking methods. Among them, Chinese patent CN 219407825 U discloses a powder transfer hopper, which includes a support frame and a hopper body. The bottom of the support frame has space for insertion and lifting, and the hopper body can suppress the floating dust generated when filling powder.

[0003] However, due to the special nature of the dust, leakage always occurs at the connection point when filling the hopper with this powder transfer hopper, polluting the environment, creating a poor working environment for personnel, and posing a significant health hazard to workers. Furthermore, to ensure the suspended powder in the tank and pipelines settles, the tank is left to stand for a long time to allow the dust to settle naturally, greatly affecting the transfer efficiency and the production efficiency of related processes, resulting in poor economic benefits and causing problems for production enterprises. Summary of the Invention

[0004] Therefore, it is necessary to provide a powder docking device to address the shortcomings of existing technologies, such as dust pollution in the working environment and low transfer efficiency.

[0005] The technical solution of the present invention is as follows: a powder docking device, comprising a feeding device, a transfer cylinder, an adjusting component, a docking plate mounted on the adjusting component, a first connecting pipe connecting the transfer cylinder and the feeding device, a second connecting pipe connecting the transfer cylinder and the docking plate, a support base located below the docking plate, a transfer tank placed on the support base and removable from the support base, a pulse gas generator, and an air pump. The adjusting component drives the docking plate to adjust its position, allowing the docking plate to move to a position where it docks with the transfer tank. The transfer cylinder is equipped with a jet nozzle and a valve interface. The transfer tank includes a tank body and a breathing filter for internal pressure regulation of the tank body. During material receiving, the docking plate docks with the transfer tank. After material receiving is completed, before the docking plate detaches from the transfer tank, the external pulse gas generator injects high-pressure pulse gas into the transfer cylinder through the jet nozzle. After the pulse gas stops, the external air pump extracts the powder-containing gas from the transfer cylinder, the first connecting pipe, the second connecting pipe, and the space above the tank body through the valve interface.

[0006] In one embodiment, both the first connecting pipe and the second connecting pipe are telescopic pipes, which can be contracted or extended axially.

[0007] In one embodiment, the feeding device includes a conveyor for feeding and a first regulating valve, the first regulating valve being connected to the conveyor and a first connecting pipe. The powder receiving device also includes a second regulating valve, which is installed on a valve port and connected to an external air pump. When receiving material, the first regulating valve is open and the second regulating valve is closed. When an external pulse gas generator injects high-pressure pulse gas into the transfer cylinder through a jet nozzle, the first regulating valve is closed and the second regulating valve is closed. When the external air pump extracts gas containing powder through the valve port, the first regulating valve is closed and the second regulating valve is open.

[0008] In one embodiment, the support frame includes a base frame and a support plate mounted on the center of the base frame. The adjustment assembly includes a plurality of drive cylinders and a plurality of guide rods. The adapter cylinder and the drive cylinders are mounted on the support plate of the support frame. The piston rod on the drive cylinder passes through the support plate and is connected to the docking plate. The guide rod passes through the support plate and is connected to the docking plate.

[0009] In one embodiment, the docking plate is provided with a conduit for connecting to a second connecting pipe, and a sealing gasket is provided at the bottom of the docking plate.

[0010] In one embodiment, the transfer tank further includes an upper cover installed at the upper end of the tank body, the breathing filter is installed on the upper cover, and the upper cover is provided with a feed pipe with an opening. When the docking plate moves to the position of docking with the transfer tank, the sealing gasket fits against the edge of the opening of the feed pipe.

[0011] In one embodiment, the support base includes a base on which a plurality of guide feet are provided, the guide feet forming a positioning space for fixing the transfer tank.

[0012] In one embodiment, the inner side of the guide foot is provided with a guide groove that gradually narrows from top to bottom toward the positioning space, and the transfer tank also includes a fixing frame connected to the outer side of the tank body. The fixing frame of the transfer tank is engaged into the positioning space through the guide groove.

[0013] In one embodiment, the load-bearing base further includes a weighing module, a metering frame, and a shock absorber. The metering frame is mounted on the weighing module, the base is located above the metering frame, and the shock absorber is located between the base and the metering frame.

[0014] In one embodiment, a vibrating motor is also included, which contacts the tank directly or indirectly and drives the tank to vibrate.

[0015] The beneficial effects of the powder docking device of the present invention are as follows: By using a first connecting pipe to connect the transfer cylinder and the feeding device, and a second connecting pipe to connect the transfer cylinder and the docking plate, and setting a sealing gasket on the docking plate to cooperate with the transfer tank, the entire channel between the transfer tank and the feeding device is isolated from the outside during the material receiving process. Furthermore, an air nozzle and a valve interface are set on the transfer cylinder. Before the docking plate is separated from the transfer tank, an external pulse gas generator injects high-pressure pulse gas into the transfer cylinder through the air nozzle. After the pulse gas stops, an external air pump extracts the powder-containing gas from the transfer cylinder, the first connecting pipe, the second connecting pipe, and the space above the tank through the valve interface. This prevents the powder-containing gas and the powder attached to the inner walls of the transfer cylinder, the first connecting pipe, and the second connecting pipe from entering the external working space after the docking plate is separated from the transfer tank. The powder docking device of the present invention effectively improves the working environment, reduces the physical harm to workers during the powder transfer process, and improves the transfer efficiency, thereby increasing the economic efficiency of enterprises. It is highly practical and has strong promotional significance. Attached Figure Description

[0030] Please see Figures 1 to 3 The present invention provides a powder docking device, including a feeding device 10, a support frame 60, an adapter cylinder 30 and an adjustment component 70 mounted on the support frame 60, a docking plate 50 mounted on the adjustment component 70, a first connecting pipe 20 connecting the adapter cylinder 30 and the feeding device 10, a second connecting pipe 40 connecting the adapter cylinder 30 and the docking plate 50, a support seat 90 located below the docking plate 50, and a transfer tank 80 placed on the support seat 90 and removable from the support seat 90. The adjustment component 70 drives the docking plate 50 to adjust its position, so that the docking plate 50 can be moved to a position to dock with the transfer tank 80, or moved upward away from the transfer tank 80.

[0031] In this embodiment, both the first connecting pipe 20 and the second connecting pipe 40 are telescopic pipes, which contract through pleats, allowing them to contract or extend axially. In other embodiments, the telescopic pipes can also be in the form of a pipe arrangement, as long as a flexible connection and vibration isolation are achieved. By setting the first connecting pipe 20 and the second connecting pipe 40, vibration can be effectively isolated, preventing the transmission of vibration between the feeding device 10, the adapter cylinder 30, and the transfer tank 80. Furthermore, the docking plate 50 connected to the second connecting pipe 40 can be adjusted vertically.

[0032] Please continue reading. Figures 4 to 7 The feeding device 10 includes a conveyor 11 for feeding and a first regulating valve 12. The first regulating valve 12 connects the conveyor 11 and a first connecting pipe 20. The conveyor 11 is connected to an external silo. In this embodiment, the first regulating valve 12 is a butterfly valve, and the conveyor 11 is a screw conveyor. The screw conveyor uses helical blades to deliver the powder forward. In other embodiments, the first regulating valve 12 can also be other types of valve switches, as long as it can control the opening and closing of the pipeline between the conveyor 11 and the first connecting pipe 20. In addition, the feeding device 10 can also use other forms to deliver the powder, as long as it can transfer the powder to the inlet of the first regulating valve 12.

[0033] The support frame 60 includes a base frame 61, a connecting rod 62 vertically installed at a corner of the base frame 61, and a support plate 63 installed at a center of the base frame 61. The adapter cylinder 30 is installed on the support plate 63, and the connecting rod 62 is connected to an external machine frame or factory building.

[0034] The adjustment assembly 70 includes several drive cylinders 71 and several guide rods 72. The drive cylinders 71 are mounted on the support plate 63 of the support frame 60. The piston rods of the drive cylinders 71 pass through the support plate 63 and are connected to the docking plate 50. The guide rods 72 also pass through the support plate 63 and are connected to the docking plate 50. The docking plate 50 is provided with a conduit 51 for connecting to the second connecting pipe 40. A sealing gasket 52 is provided at the bottom of the docking plate 50, and the sealing gasket 52 surrounds the outside of the bottom outlet of the conduit 51.

[0035] The adapter cylinder 30 has a hollow structure and is equipped with several jet nozzles 31 and a valve interface 32. Both the jet nozzles 31 and the valve interface 32 are connected to the hollow structure inside the adapter cylinder 30. The jet nozzles 31 are evenly spaced along the circumferential direction of the outer surface of the adapter cylinder 30. The invention also includes a pulse gas generator and an air pump. The jet nozzles 31 are connected to an external pulse gas generator, which delivers pulsed gas (i.e., intermittent compressed gas) into the adapter cylinder 30 through the jet nozzles 31. Furthermore, the invention includes a second regulating valve 33. In this embodiment, the second regulating valve 33 is a butterfly valve, installed on the valve interface 32 and connected to an external air pump. The air pump can extract powder floating in the first connecting pipe 20, the adapter cylinder 30, the second connecting pipe 40, and the transfer tank 80 through the second regulating valve 33.

[0036] Please continue reading. Figure 8 The transfer tank 80 includes a tank body 81, an upper cover 83 mounted on the upper part of the tank body 81, a breather filter 84 mounted on the upper cover 83, a fixing bracket 82 connected to the outer side of the tank body 81, a discharge pipe 85 located below the tank body 81, and a third regulating valve 86 connecting the discharge pipe 85 and the tank body 81. The upper cover 83 has an inlet pipe 831 with an opening. The tank body 81 has a hollow structure, and the breather filter 84 is connected to the hollow structure inside the tank body 81. The breather filter 84 is used to regulate the air pressure inside the tank body 81. When the air pressure inside the tank body 81 is less than a threshold, the breather filter 84 is in the air intake state, and fresh air from the outside enters the tank body 81. Conversely, when the air pressure inside the tank body 81 is greater than the threshold, the breather filter 84 is in the depressurization state, and the breather filter filters the exhaled air to prevent powder from flowing out with the air.

[0037] The present invention also includes a vibrating motor 100, which contacts the tank 81 directly or indirectly. The vibrating motor 100 drives the tank 81 to vibrate, compacting the powder falling into the tank 81, improving the powder density, and effectively utilizing the internal space of the tank 81. In this embodiment, the vibrating motor 100 is mounted on a support base 90.

[0038] The load-bearing base 90 includes a weighing module 91, a metering frame 92 mounted on the weighing module 91, a base 93 vertically positioned above the metering frame 92, and a shock absorber 94 positioned between the base 93 and the metering frame 92. The base 93 is provided with a plurality of guide feet 931, which together form a positioning space for fixing the transfer tank 80. The inner side of the guide feet 931 is provided with a guide groove 932 that gradually narrows from top to bottom toward the positioning space. The fixing frame 82 of the transfer tank 80 is inserted into the positioning space through the guide groove 932.

[0039] In this embodiment, the vibrating motor 100 is mounted on the base 93, and the vibrating motor 100 transmits vibrations to the transfer tank 80 mounted on the base 93 through the base 93. The shock absorber 94 is used to absorb vibrations, reduce the impact of the base 93 vibration on the weighing module 91 during weighing operations, and at the same time reduce the impact force on the weighing module 91 when the transfer tank 80 is installed, thereby improving the service life of the weighing module 91.

[0040] The working process of the powder docking device of the present invention is described in detail below:

[0041] like Figure 9 As shown, during material receiving, the transfer tank 80 is transported to the receiving point by the trolley 200 and placed on the designated base 93. The drive cylinder 71 on the adjustment assembly 70 operates, and the piston rod of the drive cylinder 71 drives the docking plate 50 to begin descending. Under the limit of the guide rod 72, when the sealing gasket 52 of the docking plate 50 reaches the position of the upper cover 83 of the transfer tank 80, the sealing gasket 52 is in contact with the opening edge of the feed pipe 831 and is pressed tightly under the action of the drive cylinder 71 to ensure no air leakage. At the same time, after sending a position arrival signal, the material transfer device performs a status self-check to ensure that the first regulating valve 12 is open and the second regulating valve 33 is closed. At this time, the screw conveyor is started to receive the material. The powder material reaches the inside of the tank 81 along the first connecting pipe 20, the transfer cylinder 30, and the second connecting pipe 40. After the powder material is added, the pressure of the gas inside the tank 81 increases, causing expansion, and overflowing along the breather filter 84 of the transfer tank 80.

[0042] The vibrating motor 100 starts to vibrate, and the vibration is transmitted to the transfer tank 80 placed on the base 93 through the base 93, which compacts the powder, increases the space inside the tank, and at the same time prevents the powder from accumulating in the feed pipe 831, which would hinder the powder from falling and affect the feeding speed.

[0043] During the material receiving process, the weighing module 91 initially determines the weight of the powder in the tank 81 and determines whether to stop feeding based on the weighing information. After the powder is received, the first regulating valve 12 is closed, and the external pulse gas generator injects high-pressure pulse gas into the adapter cylinder 30 through the jet nozzle 31, blowing off the powder adhering to the inner wall of the adapter cylinder 30. At the same time, it shakes off the powder adhering to the inner walls of the first connecting pipe 20 and the second connecting pipe 40. After the pulse gas stops, the second regulating valve 33 is opened, and the air pump extracts the powder-containing gas from the adapter cylinder 30, the first connecting pipe 20, the second connecting pipe 40, and the space above the tank 81 and puts it into the factory's own dust collector to ensure clean air in the working environment. Clean air from outside enters through the breathing filter 84. Then, the drive cylinder 71 drives the docking plate 50 to move away from the tank 81, so that the docking plate 50 disengages from the feed pipe 831 of the upper cover 83 and returns to its original position.

[0044] Weighing module 91 begins to recheck the weight of the powder in tank 81, verifying whether the weight of the powder received this time is within the deviation range from the planned weight. Then, the transfer tank 80 is lifted off the base 93 by trolley 200 and transferred to the feeding point of the next process.

[0045] The beneficial effects of the powder receiving device of the present invention are as follows: by using a first connecting pipe 20 to connect the transfer cylinder 30 and the feeding device 10, and a second connecting pipe 40 to connect the transfer cylinder 30 and the receiving plate 50, and by setting a sealing gasket 52 on the receiving plate 50 to cooperate with the intermediate tank 80, the entire channel between the intermediate tank 80 and the feeding device 10 is isolated from the outside during the receiving process. Furthermore, by setting a jet nozzle 31 and a valve interface 32 on the transfer cylinder 30, before the receiving plate 50 is separated from the intermediate tank 80, an external pulse gas generator injects high-pressure pulse gas into the transfer cylinder 30 through the jet nozzle 31. After the gas pulse stops, the external air pump extracts the powder-containing gas from the upper space of the transfer cylinder 30, the first connecting pipe 20, the second connecting pipe 40, and the tank 81 through the valve interface 32. This prevents the powder-containing gas and the powder adhering to the inner walls of the transfer cylinder 30, the first connecting pipe 20, and the second connecting pipe 40 from entering the external working space after the docking plate 50 separates from the transfer tank 80. The powder docking device of this invention effectively improves the working environment, reduces the physical harm to workers during the powder transfer process, and improves transfer efficiency, thereby increasing the economic efficiency of enterprises. It is highly practical and has strong promotional significance.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
