Description

Technical Field

[0001] The invention relates to the technical field of powder conveying, and in particular to raw material conveying equipment for producing silicon micropowder for dry-type transformers. Background Art

[0002] Silicon powder for dry-type transformers is an important material for dry-type transformers. In the manufacture of dry-type transformers, silicon powder is usually added as a filler to insulating materials such as epoxy resin to fill the gaps in epoxy resin cured products, increase the density and strength of the cured products, and improve the overall performance of the transformer. Silicon powder usually needs to be transported during production, usually by pneumatic transport; Since the particles of silicon micropowder are extremely small, they are prone to compaction and blockage during transportation. The tiny particle size will cause further compaction once blockage occurs, making the blockage more serious. In addition, the powder is prone to adhesion during transportation, which can easily cause waste of raw materials. The extremely small powder also means that dust is easily generated during transportation. Therefore, we proposed a raw material conveying equipment for the production of dry-type transformer silicon micropowder. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a raw material conveying equipment for producing dry-type transformer silicon powder, comprising: A bottom plate, and a bracket arranged on the top of the bottom plate; A conveying mechanism, which is a pneumatic conveying mechanism, for conveying powdered silicon micropowder; The top of the bottom plate is fixedly connected to the bottom of the bracket, the conveying mechanism is arranged on the top of the bottom plate, and the surface of the conveying mechanism is fixedly connected to the inner side surface of the bracket; Wherein, the conveying mechanism comprises: A pump body, the pump body is used to provide power for conveying, and a first connecting pipe is arranged on a side of the pump body close to the bottom plate, and a second connecting pipe is arranged on a side of the pump body away from the first connecting pipe; A conveying pipe, the inner and outer sides of which are both configured to be corrugated, for conveying powdered silicon micropowder; A feeding component, which has a conical structure and is used for feeding silicon micropowder; A material unloading component, which has a material blocking structure for preventing dust from being generated during unloading; The surface of the pump body is fixedly connected to the inner side of the bracket, the side of the pump body close to the bottom plate is fixedly connected to the end of the first connecting pipe, the outer side of the first connecting pipe away from the end of the pump body is fixedly connected to the inner side of the delivery pipe, the end of the delivery pipe away from the first connecting pipe is fixedly connected to the feeding assembly, the side of the pump body away from the first connecting pipe is fixedly connected to the end of the second connecting pipe, the end of the second connecting pipe away from the pump body is fixedly connected to the side of the feeding assembly close to the bottom plate, the pump body is started, and the feeding is carried out from the feeding assembly, and the silicon powder passes through the feeding assembly, the second connecting pipe and the feeding assembly in sequence. The connecting pipe, the pump body, the first connecting pipe, and the conveying pipe finally reach the predetermined conveying position through the unloading assembly to complete the conveying of the silicon micropowder. Since the inner and outer sides of the conveying pipe are both configured to be corrugated, the diameter of the conveying pipe changes continuously when the silicon micropowder is conveyed inside the conveying pipe, so that the speed during conveying changes intermittently, and the compactness of the silicon micropowder during conveying changes continuously, so that compaction blockage is not easy to occur, and blockage caused by conveying the silicon micropowder at the same speed is avoided. At the same time, the silicon micropowder continuously impacts during conveying, and even if a small blockage occurs, it can be cleared in the subsequent impact.

[0004] Furthermore, a dredging groove is provided inside the delivery pipe, and the cross-section of the dredging groove is configured to be corrugated, a fixing sleeve is provided outside the delivery pipe, and the outer side surface of the delivery pipe is fixedly connected to the inner side surface of the fixing sleeve, the surface of the fixing sleeve is fixedly connected to the top of the bottom plate, and the delivery pipe has a certain elasticity. When blockage occurs, the inner side surface of the delivery pipe can be deformed, and the space of the dredging groove is reduced, thereby increasing the inner diameter of the delivery pipe to complete the dredging when blocked. The dredging groove and the delivery pipe are both configured to be corrugated, so that when the delivery pipe is deformed, the deformation amplitude is larger, providing a better dredging effect, and the fixing sleeve fixes the outer side surface of the delivery pipe to avoid deformation of the outer side surface of the delivery pipe, maintain the shape of the dredging groove, and ensure the clearing effect.

[0005] Furthermore, a connecting rod is provided inside the dredging groove, and the connecting rod is fixedly connected to the inner side surface of the dredging groove at the larger diameter. An impact block is fixedly connected to one end of the connecting rod close to the axis of the conveying pipe, and the impact block is set to an elliptical shape. The impact block is set at a recessed position on the inner side of the dredging groove facing the axis of the conveying pipe. During transportation, the silicon micropowder continuously impacts the inner side surface of the conveying pipe, causing it to deform and impact the impact block, shaking off the adhered silicon micropowder, thereby stripping off the silicon micropowder adhered to the inner side surface of the conveying pipe to the greatest extent before the end of transportation, avoiding waste of silicon micropowder, and the elliptical impact block has smaller contact surfaces at both ends, which can provide better impact effect and strip off the silicon micropowder more thoroughly.

[0006] Furthermore, the connecting rods are arranged in several groups along the circumference of the conveying pipe, and each group of connecting rods is arranged in several groups along the axial direction of the conveying pipe. The impact blocks are arranged corresponding to the number of connecting rods. The circumferentially distributed impact blocks can evenly shake off the annular inner surface of the conveying pipe, and the axially arranged impact blocks can shake off the entire conveying pipe, thereby ensuring the maximum peeling of the silicon micropowder.

[0007] Furthermore, the feeding assembly includes a feeding barrel, which is arranged in a cone shape, and a side of the feeding barrel close to the bottom plate is fixedly connected to an end of the second connecting tube away from the pump body, and a cover plate is fixedly connected to the side of the feeding assembly away from the second connecting tube, a feeding tube is penetrated through the center of the cover plate, and the outer side surface of the feeding tube is fixedly connected to the inner side surface of the cover plate, and a column is fixedly connected to a side of the bracket close to the feeding barrel, and an end of the column away from the bracket is fixedly connected to a side of the feeding barrel close to the bracket. When feeding, the feeding pipeline is connected through the feeding tube, and then the silicon micropowder enters the inside of the feeding barrel through the feeding tube, and finally enters the second connecting tube. The cover plate can be provided to block the dust generated during feeding, so as to avoid waste of raw materials caused by dust. The conical feeding barrel can accommodate more raw materials at one time, thereby improving the feeding efficiency.

[0008] Furthermore, an inclined cone plate is provided inside the loading barrel, the inclined cone plate is recessed toward the side away from the cover plate, and there are several inclined cone plates, the outer side surface of the inclined cone plate away from the cover plate is fixedly connected to the inner side surface of the loading barrel, and the centers of several inclined cone plates are all provided with holes, and the openings of several inclined cone plates gradually decrease toward the side away from the cover plate, the silicon micropowder enters the loading barrel, and slides along the surface of the inclined cone plate to the opening, and several inclined cone plates block the descent of the silicon micropowder, making it fall multiple times to avoid direct falling and causing large dust, and the gradually decreasing inner diameter of the inclined cone plate can further slow down its falling speed, so that the silicon micropowder can descend at a nearly uniform speed inside the loading barrel, thereby ensuring smooth loading.

[0009] Furthermore, gaps are left between the outer side surfaces of several inclined cone plates close to the cover plate and the loading barrel, and connecting blocks are provided at the intervals of several inclined cone plates. The connecting blocks are set to an elliptical shape, and the two sides of the connecting blocks are respectively fixedly connected to the sides of two adjacent inclined cone plates close to each other. During loading, part of the raw materials falls along the openings of the inclined cone plates, and the other part of the raw materials falls along the gap between the inclined cone plates and the loading barrel. When one of the several openings is blocked, the raw materials falling from the gap drive the gas flow inside the loading barrel, thereby unblocking the openings. When the gap is blocked, the raw materials at the openings fall to unblock the gap, and the probability of several openings and gaps being blocked at the same time is extremely low, which can avoid blockage during loading, avoid downtime for maintenance, and ensure transportation efficiency. The connecting blocks are set to an elliptical shape, which can avoid the connecting blocks from forming steps at the intervals between the inclined cone plates, and the smooth connecting blocks can ensure that the raw materials will not remain on the surface of the connecting blocks.

[0010] Furthermore, the unloading assembly includes a frame, which is arranged at one end of the conveying pipe away from the first connecting pipe, the inner side surface of the frame is fixedly connected to the outer side surface of the conveying pipe, and the frame gradually expands outward toward the side away from the conveying pipe. The gradually outward expanding frame can prevent silicon micropowder from being blocked inside the frame.

[0011] Furthermore, an inclined baffle is provided on the side of the frame away from the conveying pipe, the side of the inclined baffle away from the bottom plate is fixedly connected to the inner side surface of the frame, and the side of the inclined baffle close to the bottom plate is inclined toward the conveying pipe, the inclined baffle is made of elastic material, the raw material enters the frame, and finally reaches the conveying position from the gap between the inclined baffle and the frame, the setting of the inclined baffle can block the dust generated during material unloading to prevent the dust from leaving the frame, the inclined baffle is inclined toward the inside of the frame, the raw material hits the inclined baffle, and finally slides along the inclined baffle, thereby ensuring that the raw material can completely leave the frame and avoiding waste of raw materials.

[0012] Furthermore, a spring rod is fixedly connected to a side of the inclined baffle away from the conveying pipe, one end of the spring rod away from the inclined baffle is fixedly connected to a side of the frame away from the conveying pipe, and the spring rod is arranged on a side of the frame away from the bottom plate. When a gap between the inclined baffle and the frame is blocked, the elastically arranged inclined baffle is deformed to clear the blockage, thereby driving the spring rod to bend. After the blockage is cleared, the spring rod and the inclined baffle are reset. The arrangement of the spring rod can limit the deformation of the inclined baffle, avoid the arbitrary deformation of the inclined baffle, and thus avoid the swing of the inclined baffle to generate dust.

[0013] The present invention has the beneficial effects: 1. The present invention provides a conveying mechanism. Since the inner and outer sides of the conveying pipe are both configured to be corrugated, when the silicon micropowder is conveyed inside the conveying pipe, the diameter of the conveying pipe changes continuously, so that the speed of the conveying pipe changes intermittently, and the compactness of the silicon micropowder changes continuously during the conveying, so that compaction blockage is not easy to occur, and blockage caused by conveying the silicon micropowder at the same speed is avoided. At the same time, the silicon micropowder continuously impacts during the conveying, and even if a small blockage occurs, it can be unblocked in the subsequent impact.

[0014] 2. The present invention provides a dredging groove, and both the dredging groove and the conveying pipe are configured to be corrugated, so that when the conveying pipe is deformed, the deformation amplitude is larger, and a better dredging effect is provided. The fixed sleeve fixes the outer side surface of the conveying pipe to avoid deformation of the outer side surface of the conveying pipe, maintains the shape of the dredging groove, and ensures the clearing effect. During transportation, the silicon micropowder continuously impacts the inner side surface of the conveying pipe, causing it to deform, and collides with the impact block to shake off the adhered silicon micropowder, so that before the end of transportation, the silicon micropowder adhered to the inner side surface of the conveying pipe is stripped to the greatest extent, avoiding waste of silicon micropowder. The elliptical impact block has smaller contact surfaces at both ends, which can provide a better impact effect and strip the silicon micropowder more thoroughly. The circumferentially distributed impact blocks can shake off the annular inner side surface of the conveying pipe evenly, and the axially arranged impact blocks can shake off the entire conveying pipe to ensure maximum stripping of the silicon micropowder.

[0015] 3. The present invention sets a feeding component, and several inclined cone plates block the descent of silicon micropowder, so that it falls multiple times to avoid direct falling and causing large dust. The gradually decreasing inner diameter of the inclined cone plate can further slow down its falling speed, so that the silicon micropowder can descend at a uniform speed inside the feeding barrel, thereby ensuring smooth feeding. When one of the several openings is blocked, the raw material falling from the gap drives the gas flow inside the feeding barrel, thereby unblocking the opening. When the gap is blocked, the raw material at the opening falls to unblock the gap, and the probability of several openings and gaps being blocked at the same time is extremely low, which can avoid blockage during feeding, avoid shutdown for maintenance, and ensure transportation efficiency. The connecting block is set to an elliptical shape, which can avoid the connecting block from forming steps at the interval of the inclined cone plates, and the smooth connecting block can ensure that the raw material will not remain on the surface of the connecting block.

[0016] 4. The present invention provides a material discharging component and a frame that gradually expands outward, thereby preventing silicon micropowder from being blocked inside the frame. The inclined baffle can shield the dust generated during material discharging and prevent the dust from leaving the frame. The inclined baffle is inclined toward the inside of the frame, and the raw materials hit the inclined baffle and finally slide down along the inclined baffle, thereby ensuring that the raw materials can completely leave the frame and avoiding waste of raw materials. The elastic rod can limit the deformation of the inclined baffle to avoid arbitrary deformation of the inclined baffle, thereby preventing the inclined baffle from swinging and generating dust.

[0024] Example 2, please refer to Figure 1-Figure 9The feeding assembly 36 includes a feeding barrel 361, which is set in a conical shape. The side of the feeding barrel 361 close to the bottom plate 1 is fixedly connected to the end of the second connecting pipe 35 away from the pump body 31. The side of the feeding assembly 36 away from the second connecting pipe 35 is fixedly connected to a cover plate 362. A feeding pipe 363 is provided through the center of the cover plate 362, and the outer side of the feeding pipe 363 is fixedly connected to the inner side of the cover plate 362. The side of the bracket 2 close to the feeding barrel 361 is fixedly connected to a column. 366, one end of the column 366 away from the bracket 2 is fixedly connected to the side of the loading barrel 361 close to the bracket 2. When loading, the loading pipe is connected through the loading pipe 363, and then the silicon micropowder enters the loading barrel 361 through the loading pipe 363, and finally enters the second connecting pipe 35. The cover plate 362 is set to block the dust generated during loading to avoid waste of raw materials caused by dust. The conical loading barrel 361 can accommodate more raw materials at one time, thereby improving the loading efficiency.

[0025] An inclined cone plate 364 is provided inside the loading barrel 361. The inclined cone plate 364 is recessed toward the side away from the cover plate 362, and there are several inclined cone plates 364. The outer side surface of the inclined cone plate 364 away from the cover plate 362 is fixedly connected to the inner side surface of the loading barrel 361, and the centers of several inclined cone plates 364 are all provided with holes, and the openings of several inclined cone plates 364 gradually decrease toward the side away from the cover plate 362. Silicon micropowder enters the loading barrel 361 and slides along the surface of the inclined cone plate 364 to the opening. Several inclined cone plates 364 block the descent of the silicon micropowder, causing it to fall multiple times to avoid direct falling and causing large amounts of dust. The gradually decreasing inner diameter of the inclined cone plate 364 can further slow down its falling speed, so that the silicon micropowder can descend at a nearly uniform speed inside the loading barrel 361, thereby ensuring smooth loading.

[0026] There is a gap between the outer side of several inclined cone plates 364 near the cover plate 362 and the loading barrel 361. A connecting block 365 is provided at the intervals between the several inclined cone plates 364. The connecting block 365 is set to be elliptical, and the two sides of the connecting block 365 are respectively fixedly connected to the sides of two adjacent inclined cone plates 364 close to each other. When loading, part of the raw material falls along the opening of the inclined cone plate 364, and the other part of the raw material falls along the gap between the inclined cone plate 364 and the loading barrel 361. When one of the several openings is blocked, the gap The falling raw materials drive the gas flow inside the loading barrel 361, thereby clearing the openings. When the gaps are blocked, the raw materials at the openings fall to clear the gaps. The probability of several openings and gaps being blocked at the same time is extremely low, which can avoid blockage during loading and maintenance, thereby ensuring the conveying efficiency. The connecting block 365 is set to an elliptical shape, which can avoid the connecting block 365 from forming a step at the interval of the inclined cone plate 364. The smooth connecting block 365 can ensure that the raw material will not remain on the surface of the connecting block 365.

[0027] The unloading assembly 37 includes a frame 371, which is arranged at one end of the conveying pipe 33 away from the first connecting pipe 32. The inner side of the frame 371 is fixedly connected to the outer side of the conveying pipe 33, and the frame 371 gradually expands outward toward the side away from the conveying pipe 33.

When the gap between the inclined baffle 372 and the frame 371 is blocked, the elastically arranged inclined baffle 372 is deformed to clear the blockage, and at the same time drives the spring rod 373 to bend. After the blockage is cleared, the spring rod 373 and the inclined baffle 372 are reset. The setting of the spring rod 373 can limit the deformation of the inclined baffle 372, avoid the arbitrary deformation of the inclined baffle 372, and thus avoid the swing of the inclined baffle 372 to generate dust.

When feeding, part of the raw materials fall along the opening of the inclined cone plate 364, and the other part of the raw materials fall along the gap between the inclined cone plate 364 and the feeding barrel 361, and finally enter the second connecting pipe 35. When one of the openings is blocked, the raw materials falling from the gap drive the gas flow inside the feeding barrel 361, thereby unblocking the opening. When the gap is blocked, the raw materials at the opening fall to unblock the gap, and the pump body 31 is started. The silicon powder passes through the feeding assembly 36, the second connecting pipe 35, the pump body 31, the first connecting pipe 32, and the conveying pipe in sequence. 33, the silicon micropowder continuously impacts the inner side of the conveying pipe 33, causing it to deform, and impacts the impact block 310, shaking off the adhered silicon micropowder. When blockage occurs, the inner side of the conveying pipe 33 can be deformed, and the space of the dredging groove 38 is reduced, thereby increasing the inner diameter of the conveying pipe 33, completing the dredging when blocked, and the raw material enters the frame 371, and finally reaches the conveying position from the gap between the inclined baffle 372 and the frame 371. When the gap between the inclined baffle 372 and the frame 371 is blocked, the elastically arranged inclined baffle 372 is deformed, thereby clearing the blockage and driving the elastic rod 373 to bend. After the blockage is cleared, the elastic rod 373 and the inclined baffle 372 are reset.
