Description

Technical Field

[0001] The present invention relates to the technical field of powder recovery, and specifically relates to a filtering pipe for powder recovery with an anti-blocking structure. Background Technique

[0002] Powder recovery refers to the process of recycling and reusing powdered materials. Many powders are raw materials with certain value, such as metal powders, plastic powders, ceramic powders, etc. Through recovery, these powders can be re-introduced into production, reducing the demand for new raw materials, thereby saving resources. If powders are randomly discharged or discarded, it will not only cause waste of resources, but may also cause environmental pollution. For example, some chemical powders may pollute the soil, water source and air. Through recovery treatment, the harm of powders to the environment can be reduced. And the recovery of powders usually refers to the filtration and recovery treatment of powders suspended in gas or liquid. The fluid (gas or liquid) containing powders filters out the powders when passing through the pipeline from the production equipment and conducts recovery treatment;

[0003] When filtering the powders in the fluid, a filter plate with the same aperture as the filtering pipe is usually used for filtration. However, after the filter holes are opened on the filter plate with the same aperture as the filtering pipe, the flow area through which the fluid can pass is reduced, affecting the flow rate of the fluid and resulting in poor conveying efficiency. Therefore, we propose a filtering pipe for powder recovery with an anti-blocking structure. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a filtering pipe for powder recovery with an anti-blocking structure, including a conveying pipe. The feeding port of the conveying pipe is communicated with a filtering device. The bottom of the filtering device is fixedly connected with a discharging device, and the bottom of the discharging device is fixedly connected with a pressing device;

[0005] The filtering device includes a circular sleeve. The inner wall of the circular sleeve is fixedly connected with a circular concave shell. Filtering round holes are opened on the outer side of the circular concave shell. By opening filtering round holes on the side and circumferential surface of the circular concave shell, the flow rate of the fluid passing through is increased, preventing the flow rate of the fluid from being affected after the filtering round holes are opened on the circular concave shell with the same aperture as the conveying pipe and resulting in poor conveying efficiency. A circular through hole is opened on one side of the inner wall of the circular sleeve close to the circular concave shell. A circular electric slide rail is fixedly connected to one side of the circular sleeve close to the circular through hole;

[0006] One side of the circular sleeve is communicated with the feeding port of the conveying pipe, and the bottom of the circular sleeve is fixedly connected with the top of the discharging device;

[0007] A plurality of the filtering round holes are provided, and the plurality of filtering round holes are distributed on the outer side of the circular concave shell. The circular through hole is arranged at a position on the inner wall of the circular sleeve close to the circular concave shell that is aligned with the guiding groove of the circular electric slide rail;

[0008] An inner side of the annular electric slide rail is rotatably connected with an inner slide rod. An outer side of the inner slide rod is fixedly connected with an arc-shaped baffle. When the arc-shaped baffle rotates with the inner slide rod, it always covers and seals the circular through hole, preventing the powder filtered by the filtering round holes from seeping into the annular electric slide rail through the circular through hole and affecting the rotation effect of the inner slide rod. One end of the inner slide rod away from the annular electric slide rail is fixedly connected with an arc-shaped connecting rod. One end of the arc-shaped connecting rod away from the inner slide rod is fixedly connected with a concave-shaped scraping rod. When the concave-shaped scraping rod rotates with the arc-shaped connecting rod, it always scrapes and cleans the outer side surface of the circular concave shell, preventing the powder filtered out from adhering to the outer surface of the circular concave shell and gradually accumulating to block the filtering round holes and affecting the fluid passage. One side of the concave-shaped scraping rod is fixedly connected with an inclined scraping plate. The inclined scraping plate rotating with the concave-shaped scraping rod scrapes and cleans the inner wall of the circular sleeve, preventing some of the powder filtered by the filtering round holes from adhering to various parts of the inner wall of the circular sleeve and being difficult to handle during long-term use. A bottom opening arc hole is formed at the bottom of the circular sleeve;

[0009] There are two inner slide rods, and the two inner slide rods are distributed on the inner side of the annular electric slide rail. The outer side of the inner slide rod is rotatably connected with the inner wall of the circular through hole. The outer side of the arc-shaped baffle is rotatably connected with the inner wall of the circular through hole. There are two inclined scraping plates, and the two inclined scraping plates are respectively distributed on both sides of the concave-shaped scraping rod.

[0010] Further, the blanking device includes a bottom-mounted through shell, and an arc-shaped sliding plate is penetrated and fixedly connected to one side of the bottom-mounted through shell. The arc-shaped hole is covered and blocked by moving the arc-shaped sliding plate inward, preventing the untreated powder and fluid in the circular sleeve from leaking downward when the blanking device presses and discharges the powder. A bottom-opening arc groove is formed at the bottom of the arc-shaped sliding plate, and a limit clamping plate is slidably connected to the inner wall of the bottom-opening arc groove. By arranging the limit clamping plate on one side of the bottom-mounted through shell, the arc-shaped sliding plate moving outward is slidably limited, preventing the arc-shaped sliding plate from moving outward to a position where it is separated from the bottom-mounted through shell under the influence of the thrust of the extension spring, resulting in the powder falling from the arc-shaped hole being easily leaked outward. A side-angle plate is fixedly connected to one side of the arc-shaped sliding plate, and an extension spring is fixedly connected to the side of the side-angle plate close to the arc-shaped sliding plate. The extension force of the extension spring pushes the arc-shaped push plate away from the side of the side-angle plate to align with the inner wall side of the circular sleeve for the powder to fall, preventing the arc-shaped sliding plate from moving inward to the area where the arc-shaped hole is located under the influence of external force and blocking the powder from falling. A T-shaped clamping block is rotatably connected to one side of the bottom-mounted through shell by a rotating bolt. By arranging the T-shaped clamping block on one side of the bottom-mounted through shell, the arc-shaped sliding plate moving to the inside is fixedly blocked, preventing the arc-shaped sliding plate connected to the extension spring from being affected by the thrust of the extension spring and requiring constant pressure on the arc-shaped plate, which affects the use effect. The bottom of the bottom-mounted through shell is fixedly connected to the top of the blanking device, and the top of the bottom-mounted through shell is fixedly connected to the bottom of the circular sleeve. The end of the extension spring away from the side-angle plate is fixedly connected to one side of the circular sleeve, and one side of the limit clamping plate is fixedly connected to one side of the bottom-mounted through shell. There are two T-shaped clamping blocks, and the two T-shaped clamping blocks are respectively distributed on both sides of the arc-shaped sliding plate on one side of the bottom-mounted through shell.

[0011] Further, the blanking device includes an inner inclined through-shell. Vertical sliding holes are formed on both sides of the inner wall of the inner inclined through-shell. Electric sliding rails are fixedly connected to the parts of both sides of the inner inclined through-shell close to the vertical sliding holes. A side sliding round rod is slidably connected to the inner side of the electric sliding rail. A bottom stop bar is fixedly connected to the bottom of the side sliding round rod. By arranging the bottom stop bar at the bottom of the side round rod, the guiding groove of the electric sliding rail is covered and protected, preventing the powder collected in the inner inclined through-shell from overflowing into the inner side of the electric sliding rail through the vertical sliding holes and affecting the sliding effect of the side sliding rod. One end of the side sliding round rod away from the electric sliding rail is fixedly connected to an inclined surface pressing plate. When the inclined surface pressing plate moves downward, the accumulated powder at the bottom can be compressed and pressed into a block, preventing the collected powder from accumulating loosely in one place and being prone to diffuse everywhere when discharging and recycling, which is inconvenient to use. An internal fixed rod is fixedly connected to the part of the inner wall of the inner inclined through-shell close to the bottom. A square sleeve plate is sleeved on the outer side of the internal fixed rod and rotatably connected through a bearing. A square long hole is formed in the top of the square sleeve plate. A top cover plate is fixedly connected to the part of the top of the square sleeve plate close to the square long hole. By arranging the top cover plate at the position of the square long hole on the top of the square sleeve plate, the square long hole is covered and protected, preventing the accumulated powder falling on the square sleeve plate from entering the square sleeve plate and being sandwiched between the tightening springs, which affects the use effect. A tightening spring is fixedly connected to the inner wall of the square long hole. The square sleeve plate is rotated to a vertical state by the turning force of the tightening spring, which is convenient for discharging the powder compressed into a block, preventing the need for workers to push the square sleeve plate to rotate every time discharging is required, which affects the discharging efficiency of material separation and recycling. One end of the tightening spring is fixedly connected to a middle connecting sleeve block. The bottom of the inner inclined through-shell is rotatably connected to a bottom clamping block through a rotating bolt. The top of the inner inclined through-shell is fixedly connected to the bottom of the bottom through-shell. The outer side of the side sliding round rod is fixedly connected to the inner wall of the vertical sliding hole. The inclined surface pressing plate is a square plate body with an inverted V-shaped inclined surface on the top surface. The middle connecting sleeve block is sleeved on the internal fixed rod and fixedly connected to the internal fixed rod. There are two bottom clamping blocks, and the two bottom clamping blocks are distributed at the bottom of the inner inclined through-shell.

[0012] The present invention provides a filtering device for powder recovery with an anti-blocking structure. It has the following beneficial effects:

[0013] 1. The filtering pipe for powder recycling with an anti-blocking structure increases the flow rate of fluid by opening filtering round holes on the side and circumferential surface of the circular concave shell, preventing the flow rate of fluid from being affected after the filtering round holes are opened on the circular concave shell with the same aperture as the conveying pipe, resulting in poor conveying efficiency. The stretching force of the stretching spring pushes the arc-shaped push plate away from one side of the side angle plate to align with the inner side of the inner wall of the circular sleeve shell, facilitating the falling of the powder. It prevents the arc-shaped slide plate from moving inward to the area where the arc-shaped hole is located under the influence of external force, blocking the falling of the powder. When the inclined surface pressing plate moves downward, it compresses the accumulated powder at the bottom and presses it into a block, preventing the collected powder from accumulating loosely in one place, making it easy to diffuse everywhere when discharging and recycling the powder, which is inconvenient to use.

[0014] 2. The filtering pipe for powder recycling with an anti-blocking structure is provided with a filtering device. By opening filtering round holes on the side and circumferential surface of the circular concave shell, the flow rate of fluid is increased, preventing the flow rate of fluid from being affected after the filtering round holes are opened on the circular concave shell with the same aperture as the conveying pipe, resulting in poor conveying efficiency. When the arc-shaped baffle rotates with the built-in sliding rod, it always covers and blocks the circular through-hole, preventing the powder filtered by the filtering round holes from seeping into the internal ring-shaped electric slide rail and affecting the rotation effect of the built-in sliding rod. When the concave-shaped scraping rod rotates with the arc-shaped connecting rod, it always scrapes and cleans the outer side of the circular concave shell, preventing the powder filtered out from adhering to the outer surface of the circular concave shell and gradually accumulating to block the filtering round holes and affect the passage of fluid. The inclined scraper rotating with the concave-shaped scraping rod scrapes and cleans the inner wall of the circular sleeve shell, preventing some of the powder filtered by the filtering round holes from adhering to various parts of the inner wall of the circular sleeve shell and being difficult to handle during long-term use.

[0015] 3. The filtering pipe for powder recycling with an anti-blocking structure is provided with a discharging device. The stretching force of the stretching spring pushes the arc-shaped push plate away from one side of the side angle plate to align with the inner side of the inner wall of the circular sleeve shell, facilitating the falling of the powder. It prevents the arc-shaped slide plate from moving inward to the area where the arc-shaped hole is located under the influence of external force, blocking the falling of the powder. By setting a limit clamping plate on one side of the bottom-mounted through-shell, the arc-shaped slide plate moving outward is slidably limited, preventing the arc-shaped slide plate from moving outward under the influence of the thrust of the stretching spring to a position where it is separated from the contact with the bottom-mounted through-shell, resulting in the powder falling from the arc-shaped hole being easily leaked outward. By the inward movement of the arc-shaped slide plate, the arc-shaped hole is covered and blocked, preventing the unprocessed powder and fluid in the circular sleeve shell from leaking downward when the powder pressing device presses and discharges the powder. By setting a T-shaped block on one side of the bottom-mounted through-shell, the arc-shaped slide plate moving to the inner side is resisted and fixed, preventing the arc-shaped slide plate connected to the stretching spring from being affected by the thrust of the stretching spring and requiring constant pressure on the arc-shaped plate, affecting the use effect.

[0016] 4. The filtering device for powder recycling with an anti-blocking structure is provided with a material pressing device. When the inclined pressing plate moves downward, it compresses the accumulated powder at the bottom and presses it into a block, which can prevent the collected powder from accumulating loosely in one place and being prone to spreading everywhere when discharging and recycling it, making it inconvenient to use. By arranging a bottom stop bar at the bottom of the side circular rod to cover and protect the guiding groove of the electric slide rail, it can prevent the powder collected in the inner inclined through shell from overflowing into the inner side of the electric slide rail through the vertical sliding hole and affecting the sliding effect of the side sliding rod. Through the rotational force of the tightening spring, the square sleeve plate is driven to rotate to a vertical state, which is convenient for discharging the powder compressed into a block, and can prevent the need for workers to push the square sleeve plate to rotate every time discharging is required, affecting the discharging efficiency of material separation and recycling. By arranging a top cover plate at the position of the square sleeve plate near the square long hole at the top to cover and protect the square long hole, it can prevent the accumulated powder falling on the square sleeve plate from entering the square sleeve plate and getting stuck between the tightening springs, affecting the use effect.

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 4 , the present invention provides a filtering pipe for powder recovery with an anti-blocking structure, including a conveying pipe 1. The feeding port of the conveying pipe 1 is communicated with a filtering device 2. The bottom of the filtering device 2 is fixedly connected with a discharging device 3. The bottom of the discharging device 3 is fixedly connected with a pressing device 4;

[0028] The filtering device 2 includes a circular housing 201. The inner wall of the circular housing 201 is fixedly connected with a circular concave housing 202. The outer side of the circular concave housing 202 is provided with filtering round holes 203. The inner wall of the circular housing 201 near the circular concave housing 202 is provided with a circular through hole 204. The circular housing 201 near the circular through hole 204 is fixedly connected with an annular electric slide rail 205;

[0029] One side of the circular housing 201 is communicated with the feeding port of the conveying pipe 1. The bottom of the circular housing 201 is fixedly connected with the top of the discharging device 3;

[0030] A plurality of filtering round holes 203 are provided, and the plurality of filtering round holes 203 are distributed on the outer side of the circular concave housing 202. The circular through hole 204 is arranged at a position on the inner wall of the circular housing 201 near the circular concave housing 202 and aligned with the guiding groove of the annular electric slide rail 205;

[0031] An inner side of the annular electric slide rail 205 is rotatably connected with an inner slide rod 206. An outer side of the inner slide rod 206 is fixedly connected with an arc-shaped baffle 207. One end of the inner slide rod 206 away from the annular electric slide rail 205 is fixedly connected with an arc-shaped connecting rod 208. One end of the arc-shaped connecting rod 208 away from the inner slide rod 206 is fixedly connected with a concave-shaped scraping rod 209. One side of the concave-shaped scraping rod 209 is fixedly connected with an inclined scraper 210. A bottom arc-shaped hole 211 is formed in a bottom of the circular housing 201.

[0032] There are two inner slide rods 206, and the two inner slide rods 206 are distributed on an inner side of the annular electric slide rail 205. An outer side of the inner slide rod 206 is rotatably connected with an inner wall of the circular through hole 204. An outer side of the arc-shaped baffle 207 is rotatably connected with the inner wall of the circular through hole 204. There are two inclined scrapers 210, and the two inclined scrapers 210 are respectively distributed on two sides of the concave-shaped scraping rod 209. During use, a fluid containing powder enters the filtering device 2 from a production device. The filtering device 2 filters and separates the powder from the fluid. The fluid from which the powder has been filtered will enter the conveying pipe 1. The filtered and separated powder will fall downward through the discharging device 3 and accumulate in the pressing device 4. When a certain amount of powder accumulates in the pressing device 4, the discharging device 3 is used to block the filtering device 2. At this time, the pressing device 4 can be used to press and level the accumulated powder and then the powder will fall out as a whole from the bottom of the pressing device 4.

[0033] The fluid containing powder enters the circular housing 201 from the production device and contacts the circular concave housing 202. At this time, the fluid passes through the filtering circular holes 203 formed in the circular concave housing 202 and enters the conveying pipe 1. The powder in the fluid is filtered by the filtering circular holes 203 and falls downward in the circular housing 201 and sequentially passes through the arc-shaped holes and the discharging device 3 and accumulates in the pressing device 4. By forming the filtering circular holes 203 on the side surface and the circumferential surface of the circular concave housing 202, the flow rate of the fluid passing through is increased. At the same time, the annular electric slide rail 205 drives the inner slide rod 206 to rotate, driving the outer arc-shaped baffle 207 and the arc-shaped connecting rod 208 at one end to rotate together. When the arc-shaped baffle 207 rotates with the inner slide rod 206, it always covers and blocks the circular through hole 204. When the arc-shaped connecting rod 208 rotates with the inner slide rod 206, it drives the concave-shaped scraping rod 209 at one end to rotate. When the concave-shaped scraping rod 209 rotates with the arc-shaped connecting rod 208, it always scrapes and cleans the outer side surface of the circular concave housing 202. When the concave-shaped scraping rod 209 rotates, it drives the inclined scrapers 210 on both sides to rotate. The inclined scrapers 210 rotating with the concave-shaped scraping rod 209 scrape and clean the inner wall of the circular housing 201.

[0034] Please refer to Figures 1 - 8, the present invention provides a filtering device for powder recovery with an anti-blocking structure: The discharging device 3 includes a bottom-mounted through shell 301. One side of the bottom-mounted through shell 301 penetrates and is fixedly connected to an arc-shaped sliding plate 302. A bottom-opening arc groove 303 is formed at the bottom of the arc-shaped sliding plate 302. A limiting clamping plate 304 is slidably connected to the inner wall of the bottom-opening arc groove 303. One side of the arc-shaped sliding plate 302 is fixedly connected to a side-angle plate 305. A stretching spring 306 is fixedly connected to the side of the side-angle plate 305 close to the arc-shaped sliding plate 302. One side of the bottom-mounted through shell 301 is rotatably connected to a T-shaped clamping block 307 through a rotating bolt. The bottom of the bottom-mounted through shell 301 is fixedly connected to the top of the pressing device 4. The top of the bottom-mounted through shell 301 is fixedly connected to the bottom of the circular sleeve 201. One end of the stretching spring 306 away from the side-angle plate 305 is fixedly connected to one side of the circular sleeve 201. One side of the limiting clamping plate 304 is fixedly connected to one side of the bottom-mounted through shell 301. There are two T-shaped clamping blocks 307, and the two T-shaped clamping blocks 307 are respectively distributed at positions on one side of the bottom-mounted through shell 301 on both sides of the arc-shaped sliding plate 302;

[0035] The blanking device 4 includes an inner inclined through-shell 401. Vertical sliding holes 402 are opened on both sides of the inner wall of the inner inclined through-shell 401. Electric slide rails 403 are fixedly connected to both sides of the inner inclined through-shell 401 near the vertical sliding holes 402. A side-sliding round rod 404 is slidably connected to the inner side of the electric slide rail 403. A bottom stop bar 405 is fixedly connected to the bottom of the side-sliding round rod 404. An inclined surface pressing plate 406 is fixedly connected to one end of the side-sliding round rod 404 away from the electric slide rail 403. An inner fixed rod 407 is fixedly connected to a position near the bottom of the inner wall of the inner inclined through-shell 401. A square sleeve plate 408 is sleeved on the outer side of the inner fixed rod 407 and is rotatably connected through a bearing. A square long hole 409 is opened at the top of the square sleeve plate 408. A top cover plate 410 is fixedly connected to a position near the square long hole 409 at the top of the square sleeve plate 408. A return spring 411 is fixedly connected to the inner wall of the square long hole 409. One end of the return spring 411 is fixedly connected to a middle connecting sleeve block 412. The bottom of the inner inclined through-shell 401 is rotatably connected to a bottom clamping block 413 through a rotating bolt. The top of the inner inclined through-shell 401 is fixedly connected to the bottom of the bottom through-shell 301. The outer side of the side-sliding round rod 404 is fixedly connected to the inner wall of the vertical sliding hole 402. The inclined surface pressing plate 406 is set as a square plate body with an inverted V-shaped inclined surface on the top surface. The middle connecting sleeve block 412 is sleeved on the inner fixed rod 407 and is fixedly connected to the inner fixed rod 407. There are two bottom clamping blocks 413, and the two bottom clamping blocks 413 are distributed at the bottom of the inner inclined through-shell 401. During use, the powder filtered by the filtering round holes 203 falls downward through the arc-shaped holes and passes through the bottom through-shell 301 and accumulates in the blanking device 4. The extension spring 306 on one side of the circular sleeve 201 pushes the side angle plate 305 to move away from the circular sleeve 201 through the extension force. The movement of the side angle plate 305 drives the arc-shaped sliding plate 302 on one side to move together. The extension force of the extension spring 306 pushes the arc-shaped push plate to align the side away from the side angle plate 305 with the inner wall of the circular sleeve 201 to facilitate the powder to fall. The arc-shaped sliding plate 302 moves outward until the inner wall of the bottom opening arc groove 303 abuts against the limit clamping plate 304 and then stops. The limit clamping plate 304 is arranged on one side of the bottom through-shell 301 to perform sliding limit on the outward moving arc-shaped sliding plate 302. When a certain amount of powder accumulates in the blanking device 4 and needs to be blanked, the side angle plate 305 is pushed to compress the extension spring 306 so that the arc-shaped sliding plate 302 moves inward and covers and seals the arc-shaped holes. The arc-shaped sliding plate 302 moves inward to cover and seal the arc-shaped holes. When the arc-shaped sliding plate 302 moves to completely cover and seal the arc-shaped holes, the T-shaped clamping block 307 is rotated to resist and fix the arc-shaped sliding plate 302. The T-shaped clamping block 307 is arranged on one side of the bottom through-shell 301 to resist and fix the inward moving arc-shaped sliding plate 302. After the powder falls from the bottom through-shell 301 to the square sleeve plate 408 of the inner inclined through-shell 401 and accumulates to a certain height, the arc-shaped sliding plate 302 can be used to seal the arc-shaped holes.At this time, the electric slide rail 403 drives the side slide bar to drive the arc-shaped bar at the bottom and the inclined surface pressing plate 406 at one end to move downward together. When the inclined surface pressing plate 406 moves downward, it compresses the accumulated powder at the bottom and presses it into a block. The bottom bar 405 is arranged at the bottom of the side circular rod to cover and protect the guide groove of the electric slide rail 403. After the powder on the square sleeve plate 408 is pressed and finished, the bottom block 413 can be rotated outward to release the resistance limit on the bottom of the square sleeve plate 408. At this time, the return spring 411 drives the square sleeve plate 408 to rotate around the built-in fixed rod 407 to the vertical state through the rotational force. When the square sleeve plate 408 rotates to the vertical state, the powder blocks pressed on the top will fall from the bottom of the inner inclined through shell 401. The rotational force of the return spring 411 drives the square sleeve plate 408 to rotate to the vertical state, which is convenient for discharging the compressed powder blocks. The top cover plate 410 is arranged at the top of the square sleeve plate 408 near the square long hole 409 to cover and protect the square long hole 409.,

[0036] When the present invention is operated and used, the fluid containing powder enters the filtering device 2 from the production equipment. The filtering device 2 filters and separates the powder from the fluid. The fluid from which the powder has been filtered will enter the conveying pipe 1. The filtered and separated powder will fall downward through the discharging device 3 and accumulate in the pressing device 4. When a certain amount of powder accumulates in the pressing device 4, the discharging device 3 is used to block the filtering device 2. At this time, the accumulated powder can be pressed and processed by the pressing device 4 and then fall out as a whole from the bottom of the pressing device 4;

[0037] The fluid containing powder enters the circular casing 201 from the production equipment and contacts the circular concave shell 202. At this time, the fluid passes through the filtering circular hole 203 opened on the circular concave shell 202 and enters the conveying pipe 1, and the powder in the fluid is filtered by the filtering circular hole 203 and falls downward in the circular casing 201, passes through the arc hole and the discharge device 3 in turn, and accumulates in the pressing device 4. The flow rate of the fluid passing through is increased by opening the filtering circular hole 203 on the side and the circumferential surface of the circular concave shell 202. At the same time, the annular electric slide rail 205 drives the built-in slide rod 206 to rotate, driving the outer arc baffle 207 and the arc connecting rod 208 at one end to rotate together. The arc baffle 207 is constantly aligned with the circular through hole as the built-in slide rod 206 rotates. 204 is covered and blocked, and the arc-shaped connecting rod 208 drives the concave scraper rod 209 at one end to rotate as the built-in sliding rod 206 rotates. The concave scraper rod 209 scrapes and cleans the outer side of the circular concave shell 202 at all times as the arc-shaped connecting rod 208 rotates. When the concave scraper rod 209 rotates, it drives the inclined scrapers 210 on both sides to rotate. As the concave scraper rod 209 rotates, the inclined scrapers 210 scrape and clean the inner wall of the circular sleeve 201. The powder filtered by the filtering circular hole 203 falls downward from the arc-shaped hole through the bottom shell 301 and accumulates in the pressing device 4. The extension spring 306 on one side of the circular sleeve 201 pushes the side angle plate 305 to move away from the circular sleeve 201 through the extension force. The arc slide 302 on one side is driven to move together, and the extension force of the extension spring 306 pushes the arc push plate away from the side angle plate 305 and aligns with the inner wall of the circular sleeve shell 201 to facilitate the falling of the powder. The arc slide 302 moves outward to the inner wall of the bottom arc groove 303 and stops when it conflicts with the limiting card plate 304. The limiting card plate 304 is set on the side of the bottom through shell 301 to slide and limit the arc slide 302 moving outward. When a certain amount of powder is accumulated in the pressing device 4 and needs to be pressed, the side angle plate 305 is pushed to compress the extension spring 306, so that the arc slide 302 moves inward and covers the arc hole. The arc-shaped slide 302 is moved to cover and block the arc-shaped hole. When the arc-shaped slide plate 302 moves to completely cover and block the arc-shaped hole, the T-shaped block 307 is rotated to fix the arc-shaped slide plate 302 in a blocking manner. A T-shaped block 307 is set on one side of the bottom through shell 301 to fix the arc-shaped slide plate 302 moved to the inside in a blocking manner. After the powder falls from the bottom through shell 301 to the square sleeve plate 408 of the inner oblique through shell 401 and accumulates to a certain height, the arc-shaped hole can be blocked by the arc-shaped slide plate 302. At this time, the electric slide rail 403 drives the side slide rod to drive the arc-shaped baffle bar at the bottom and the inclined pressure plate 406 at one end to move downward together. When the inclined pressure plate 406 moves downward, it compresses the accumulated powder at the bottom and presses it into a block.The guiding groove of the electric slide rail 403 is covered and protected by arranging a bottom stop strip 405 at the bottom of the side-mounted round rod. After the powder on the square sleeve plate 408 is pressed and finished, the bottom clamping block 413 can be rotated outward to release the resistance limit on the bottom of the square sleeve plate 408. At this time, the tightening spring 411 drives the square sleeve plate 408 to rotate around the built-in fixed rod 407 to the vertical state through the turning force. When the square sleeve plate 408 rotates to the vertical state, the formed powder pressed on the top will fall from the bottom of the inner inclined through shell 401. Driving the square sleeve plate 408 to rotate to the vertical state through the turning force of the tightening spring 411 is convenient for discharging the compressed and formed powder. The top cover plate 410 is arranged at the position of the square sleeve plate 408 close to the square long hole 409 at the top to cover and protect the square long hole 409.,
