Description

Technical Field

[0001] This invention relates to the technical field of powder hoppers. More specifically, this invention relates to a novel material hopper specifically for powders. Background Technology

[0002] During the powder production process, the produced powder is usually temporarily stored in finished product bins. To facilitate material retrieval from below or direct connection to the packaging station, the bins are suspended from the upper part of the factory building via several fixed suspension points on the top of the bins, with the lower part remaining suspended in the air.

[0003] To monitor the weight changes of the material inside the drum in real time, tension sensors are installed at these lifting points. However, this configuration concentrates the weight of the drum itself and the entire load of the stored powder on the limited number of lifting points and sensor connections at the top, resulting in highly concentrated stress points and poor structural stability. Under long-term load, vibration, or impacts caused by material entering or leaving the drum, the lifting points and sensor components are at risk of fatigue, deformation, or even breakage and detachment.

[0004] Meanwhile, when powder is discharged from the container, due to the characteristics of internal friction, adhesion, and flowability, "bridging" and "rat holes" are very likely to occur above the discharge port: the former refers to the powder arching to form a stable material arch, blocking the discharge channel; the latter is that the central material flows out preferentially, forming a tubular cavity, while the surrounding material remains stagnant. These poor flow conditions will cause some powder to remain in the dead zone inside the container for a long time, continuously exposed to air and moisture, leading to moisture absorption, clumping, and even deterioration, directly affecting the quality of the finished product. Summary of the Invention

[0005] In order to overcome the shortcomings of existing material buckets, such as low structural stability and the tendency to "bridge" and "rat holes", this invention provides a new type of material bucket for powder materials.

[0006] Technical solution: A novel material bucket for powder materials, comprising a connecting frame, a cylinder, and a cylindrical tube; the cylinder is fixedly connected to the connecting frame; the cylindrical tube is connected to the cylinder and fixedly connected to the cylinder; it also includes a connecting block, a telescopic cylinder, a connecting plate, a long rod, and a piston block; several connecting blocks are arranged above the cylinder; a telescopic cylinder is fixedly connected to each connecting block; the telescopic ends of all telescopic cylinders are fixedly connected to the connecting plate; a long rod is connected to the connecting plate and passes through the middle of the cylinder; the lower end of the long rod is connected to the piston block, which seals the cylinder.

[0007] More preferably, it also includes a conical block; the conical block is fixedly connected to the piston block, the conical block is fixedly connected to the long rod, and the conical block is in contact with the cylinder.

[0008] By employing the above-described structure, this invention achieves a flow guiding effect.

[0009] More preferably, the long rod has a hollow structure; the conical block has a channel one; the piston block has a channel two; the piston block has several channels three; the conical block has several inclined channels four; the long rod is connected to channel one; channel one is connected to channel two; each channel three is connected to channel two; each channel three is connected to the corresponding channel four.

[0010] More preferably, it also includes a second connecting block; the second connecting block is fixedly connected to the long rod.

[0011] More preferably, it also includes a stirring assembly, which includes stirring blades, a second circular tube, a ring, and a drive unit; several stirring blades are fixedly connected to the long rod; the second circular tube is rotatably connected to the long rod and communicates with the long rod; a ring is rotatably connected to the cylinder and is slidably connected to the long rod; and a drive unit is connected to the connecting plate, which is used to drive the long rod to rotate.

[0012] The present invention achieves a stirring effect by adopting the above structure.

[0013] More preferably, the drive unit includes a motor, gear one, and gear two; the motor is fixedly connected to the connecting plate; gear one is fixedly connected to the output shaft of the motor; gear two is fixedly connected to the long rod, and gear two meshes with gear one.

[0014] More preferably, the lower part of the cylinder is funnel-shaped.

[0015] By employing the above-described structure, this invention achieves a flow guiding effect.

[0016] More preferably, it also includes a measuring component, which includes a connecting block three, a tension sensor, and a connecting block four; several connecting blocks three are fixedly connected to the connecting frame; a tension sensor is fixedly connected to each connecting block three; and a connecting block four is fixedly connected to each tension sensor.

[0017] More preferably, it also includes a dust sensor; a dust sensor is installed on the outside of the cylinder.

[0018] By adopting the above structure, the present invention achieves dust monitoring effect.

[0019] More preferably, it also includes a vision sensor; the vision sensor is installed on the inside of the cylinder.

[0020] Compared with the prior art, the present invention has the following advantages: First, by using a long rod to frequently agitate the powder inside the cylinder, the "bridging" and "rat hole" phenomena of the powder are broken, allowing the powder to be discharged smoothly. At the same time, the long rod also works with the piston block to limit the cylinder that tends to fall, preventing it from falling to the ground, thus ensuring high safety. In addition, the long rod and the piston block are also used to open and close the lower opening of the cylinder, eliminating the need for other valve components, resulting in an ingenious structure.

[0021] Second, the residual powder is guided downwards at an angle by the cone block to prevent powder accumulation. After the cone block contacts the cylinder, only a small amount of powder will remain in the gap between the cylinder and the cone block, which greatly reduces the impact of residual powder on the sealing performance.

[0022] Third, by using a long rod, channel one, channel two, channel three and channel four in combination, an inert gas is first sprayed obliquely upward into the gap between the cylinder and the cone block, and then the cone block is controlled to fit against the cylinder, which completely avoids the problem of residual powder between the cylinder and the cone block. At the same time, after the inert gas flows into the inside of the cylinder, it can increase the fluidity of the powder in the cylinder, further reducing the problems of powder "bridging" and "rat hole".

[0023] Fourth, by supporting the powder through connecting block two, the gravity of the powder pile acting on the lower part of the cylinder is reduced, making it easier for the inert gas to blow out the powder in the gap between the cylinder and the cone block, and making it easier to form an air wall to intercept the powder. At the same time, during the material handling process, connecting block two can also improve the agitation effect on the powder, making the powder flow out more smoothly.

Detailed Implementation

[0032] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0033] Example 1: A novel material bucket for powder materials, such as... Figures 1-6 As shown, it includes a connecting frame 1, a cylinder 2, and a cylindrical tube 3; the cylinder 2 is fixedly connected to the connecting frame 1; the cylindrical tube 3 is connected and fixedly connected to the cylinder 2; it also includes a connecting block 4, a telescopic cylinder 5, a connecting plate 6, a long rod 7, and a piston block 8; several connecting blocks 4 are arranged above the cylinder 2; a telescopic cylinder 5 is fixedly connected to each connecting block 4; the telescopic ends of all the telescopic cylinders 5 are fixedly connected to the connecting plate 6; a long rod 7 is connected to the connecting plate 6, and the long rod 7 passes through the middle of the cylinder 2; the lower end of the long rod 7 is connected to the piston block 8, which seals the cylinder 2.

[0034] Working Principle: First, the connecting frame 1 is fixed to the crossbeam at the top of the factory building. The external feed pipe is connected to the circular pipe 3, and the powder is conveyed into the cylinder 2 through the external feed pipe. The cylinder 2 stores the finished powder. When material needs to be retrieved, the external container is placed directly below the cylinder 2. Then, the telescopic cylinder 5 drives the connecting plate 6 downward, which in turn drives the long rod 7 downward. The long rod 7 drives the piston block 8 downward, causing the piston block 8 to stop blocking the lower opening of the cylinder 2, allowing the powder in the cylinder 2 to flow from its lower opening into the external container. Then, the telescopic cylinder 5 controls the long rod 7 to perform high-frequency up-and-down reciprocating motion, causing the long rod 7 to frequently agitate the powder in the cylinder 2, breaking the "bridging" and "rat hole" phenomena of the powder, allowing the powder to be smoothly discharged into the external container. After material retrieval is completed, the telescopic cylinder 5 controls the long rod 7 to move upward, which in turn drives the piston block 8 upward, causing the piston block 8 to re-seal the lower opening of the cylinder 2. After a period of use, when the connection point between the connecting frame 1 and the crossbeam on the top of the factory building becomes loose, the cylinder 2 will tend to fall. At this time, the long rod 7 and the piston block 8 work together to limit the cylinder 2 and prevent it from falling to the ground, ensuring high safety. At the same time, as long as the cylinder 2 has a slight tendency to fall, the cylinder 2 can generate downward pressure on the piston block 8. The downward pressure is transmitted to the long rod 7, the connecting plate 6 and the telescopic cylinder 5 in sequence. At this time, the sensor in the telescopic cylinder 5 can detect the sudden change in tension, thereby reminding the staff to go for maintenance and avoid safety accidents. During use, the powder in the cylinder 2 is agitated by the long rod 7 at high frequency, breaking the "bridging" and "rat hole" phenomenon of the powder, so that the powder can be discharged smoothly. At the same time, the long rod 7 also works with the piston block 8 to limit the cylinder 2 when it tends to fall, preventing it from falling to the ground, ensuring high safety. In addition, the long rod 7 and the piston block 8 are also used to open and close the lower opening of the cylinder 2, eliminating the need for other valve components, making the structure ingenious.

[0035] It also includes a conical block 201; the conical block 201 is welded to the piston block 8, the conical block 201 is welded to the long rod 7, the conical block 201 is in contact with the cylinder 2, and the powder falling onto the conical block 201 can slide down its inclined surface.

[0036] The long rod 7 has a hollow structure; the conical block 201 has a channel 191; the piston block 8 has a channel 292; the piston block 8 has six channels 393; the conical block 201 has six inclined channels 494; the long rod 7 is connected to channel 191; channel 191 is connected to channel 292; each channel 393 is connected to channel 292; each channel 393 is connected to the corresponding channel 494.

[0037] Working principle: During the material handling process, some powder remains on the upper side of the piston block 8. After material handling is completed, when the piston block 8 seals the lower opening of the cylinder 2, the powder remaining on the upper side of the piston block 8 will be compacted on the lower side of the cylinder 2, resulting in low sealing between the cylinder 2 and the piston block 8, which affects the storage of powder. Therefore, a conical block 201 is set on the upper side of the piston block 8. During the process of sealing the lower opening of the cylinder 2 by the upward movement of the conical block 201 and the piston block 8 driven by the long rod 7, even if the powder in the cylinder 2 flows to the upper side of the conical block 201, the powder can flow out obliquely downward along the conical surface of the conical block 201, without overflowing. To address the powder accumulation issue, the smaller the gap between the cylinder 2 and the conical block 201, the smaller the powder flow rate. After the conical block 201 contacts the cylinder 2, only a small amount of powder remains in the gap between the cylinder 2 and the conical block 201, significantly reducing the impact of residual powder on sealing performance. During use, the conical block 201 guides the residual powder obliquely downwards to prevent powder accumulation. After the conical block 201 contacts the cylinder 2, only a small amount of powder remains in the gap between the cylinder 2 and the conical block 201, significantly reducing the impact of residual powder on sealing performance.

[0038] After material collection is completed, when the conical block 201 is about to contact the cylinder 2, a small amount of powder will still flow out from the gap between the cylinder 2 and the conical block 201. This means that even after the conical block 201 contacts the cylinder 2, a small amount of powder will remain in the gap between the cylinder 2 and the conical block 201. Therefore, an external air pump is manually connected to the second circular pipe 207. When the conical block 201 is about to contact the cylinder 2, inert gas is supplied to the second circular pipe 207 through the external air pump. The inert gas flows through the second circular pipe 207 into the long rod 7, then from the long rod 7 into the first channel 191, then from the first channel 191 into the second channel 192, then from the second channel 192 into the third channel 193, then from the third channel 193 into the fourth channel 194, and then from the fourth channel 194 it is sprayed obliquely upwards into the gap between the cylinder 2 and the conical block 201. In the gap, the powder in the gap is blown away, and an inert gas wall is formed at the gap to prevent the powder from continuing to flow into the gap between the cylinder 2 and the cone block 201. Then, the cone block 201 is controlled to move upward to fit against the cylinder 2, completely avoiding the problem of powder residue between the cylinder 2 and the cone block 201, and the sealing performance is strong. In use, by cooperating with the long rod 7, channel one 191, channel two 192, channel three 193 and channel four 194, inert gas is first sprayed obliquely upward into the gap between the cylinder 2 and the cone block 201, and then the cone block 201 is controlled to fit against the cylinder 2, completely avoiding the problem of powder residue between the cylinder 2 and the cone block 201. At the same time, after the inert gas flows into the inside of the cylinder 2, it can increase the fluidity of the powder in the cylinder 2, further reducing the problems of powder "bridging" and "rat hole".

[0039] It also includes connecting block 202; connecting block 202 is welded onto the long rod 7.

[0040] Working principle: When inert gas is sprayed to prevent powder from flowing into the gap between cylinder 2 and cone block 201, the amount of powder inside cylinder 2 is large, and the weight of the powder pile acting on the lower part of cylinder 2 is large, making powder blowing and interception difficult. Therefore, a connecting block 202 is set at the lower part of the long rod 7. Most of the weight of the powder pile acts on the connecting block 202, making it easier for the inert gas to blow out the powder in the gap between cylinder 2 and cone block 201, and easier to form an air wall to intercept the powder. During the material picking process, the long rod 7 drives the connecting block 202. 02 reciprocates up and down, and the connecting block 202 moves the powder in the lower inner part of the cylinder 2, thereby improving the powder moving effect and making the powder flow out more smoothly. In use, the connecting block 202 supports the powder, reducing the gravity of the powder pile acting on the lower part of the cylinder 2, making it easier for the inert gas to blow out the powder in the gap between the cylinder 2 and the cone block 201, and making it easier to form an air wall to intercept the powder. At the same time, during the material picking process, the connecting block 202 can also improve the powder moving effect, making the powder flow out more smoothly.

[0041] It also includes a stirring assembly, which includes stirring blades 203, a second round tube 207, a ring 2013 and a drive unit; two stirring blades 203 are bolted to the long rod 7; the second round tube 207 is connected to and rotatably connected to the long rod 7; the ring 2013 is rotatably connected to the cylinder 2 and is slidably connected to the long rod 7; the drive unit is connected to the connecting plate 6.

[0042] The drive unit includes a motor 204, a first gear 205, and a second gear 206; the motor 204 is bolted to the connecting plate 6; the output shaft of the motor 204 is fixedly connected to the first gear 205, which is made of alloy material; the second gear 206 is fixedly connected to the long rod 7, and the second gear 206 meshes with the first gear 205. The motor 204 drives the first gear 205 to rotate, the first gear 205 drives the second gear 206 to rotate, and the second gear 206 drives the long rod 7 to rotate.

[0043] The lower part of cylinder 2 is funnel-shaped, which makes it easier for the powder inside cylinder 2 to be discharged downwards.

[0044] Working principle: During the material handling process, the motor 204 is started, which drives the gear 1 205 to rotate. The gear 1 205 drives the gear 2 206 to rotate, which drives the long rod 7 to rotate. The long rod 7 drives the ring 2013 to rotate, and the long rod 7 drives the stirring blade 203 to rotate. The stirring blade 203 stirs the powder in the cylinder 2, further eliminating the "bridging" and "rat hole" phenomena of the powder.

[0045] Example 2, based on Example 1, such as Figure 7 As shown, it also includes a measuring component, which includes a connecting block 3 208, a tension sensor 209, and a connecting block 4 2010; three connecting blocks 3 208 are bolted to the connecting frame 1; a tension sensor 209 is bolted to each connecting block 3 208; and a connecting block 4 2010 is bolted to each tension sensor 209.

[0046] It also includes a dust sensor 2011; a dust sensor 2011 is installed on the outside of the cylinder 2 for monitoring the dust concentration in the surrounding environment.

[0047] It also includes a vision sensor 2012; the vision sensor 2012 is installed inside the cylinder 2 to monitor the state of the powder inside the cylinder 2.

[0048] Working principle: During installation, the connecting block 4 2010 is fixed to the crossbeam on the top of the factory building. The gravity of the cylinder 2 acts on the connecting frame 1, and then through the connecting frame 1 it acts on the connecting block 3 208, and then through the connecting block 3 208 it acts on the tension sensor 209. During the material taking process, as the powder content in the cylinder 2 decreases, the gravity detected by the tension sensor 209 decreases, thereby determining the amount of powder taken out.
