Powder screening machine

Abstract

This invention discloses an integrated powder screening machine, comprising a pulverizer and a vibrating screen. The outlet end of the pulverizer is connected to a processing box via an inflow pipe. A screening cylinder is installed inside the processing box, and a rotating cylinder is rotatably connected inside the screening cylinder. A mesh cylinder is installed on the inner part of the rotating cylinder, and a material-pushing plate is installed on the outer side of the mesh cylinder. This invention relates to the field of material screening technology. The rotating material-pushing mesh plate and material-pushing panel disperse and push the material. The material passes through the mesh holes of the material-pushing mesh plate, achieving loosening of the material. Simultaneously, when the vacuum feeder draws material from the temporary storage cylinder into the vibrating screen, multiple first fins longitudinally divide the material, allowing it to flow smoothly out in the second gap. At the same time, the spiral alloy steel wire generates a vibrating motion during the material flow, causing the cross-section of the material to be circumferentially divided into a loose state when flowing out of the first gap, further ensuring the looseness of the material.

Description

Technical Field

[0001] This invention relates to the field of material screening technology, specifically to an integrated powder screening machine. Background Technology

[0002] With the continuous improvement of industrial automation, integrated powder screening machines are being used more and more widely in various industries. Currently, after crushing materials, these machines typically directly load the crushed material into stainless steel drums for later use. However, this method has certain drawbacks in practical applications.

[0003] On the one hand, some materials contain a certain amount of moisture, which heats up during the crushing process due to friction and shearing. If this material is directly piled in stainless steel drums after crushing, it easily causes clumping. On the other hand, clumped material needs to be sucked into a vibrating screen for sieving via a vacuum feeder during subsequent use. However, during the suction and vibrating screening process, some clumps cannot be sucked in or dispersed, causing production line interruptions.

[0004] To address this issue, companies typically need to manually operate the equipment to crush the agglomerated materials, which not only increases production costs but also reduces production efficiency. Therefore, solving the agglomeration problem during the crushing process of integrated powder screening machines and improving material processing efficiency has become an urgent problem to be solved in the current powder screening machine industry. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated powder screening machine, which solves the problem of material clumping during storage after crushing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated powder screening machine, comprising a pulverizer and a vibrating screen, wherein the outlet end of the pulverizer is connected to a processing box via an inflow pipe; a vacuum suction pump is installed on the top of the vibrating screen, and the inlet end of the vacuum suction pump is connected to the processing box via a connecting hose.

[0007] The processing box is equipped with a screening cylinder, and a rotating cylinder is rotatably connected inside the screening cylinder. One end of the rotating cylinder is an open end, which is rotatably connected to the inflow pipe. The other end of the rotating cylinder is a closed end. A motor is fixed outside the processing box, and the output end of the motor passes through the outer wall of the processing box and is fixed to the closed end of the rotating cylinder.

[0008] The rotating drum is equipped with a screen cylinder inside the screening drum, and a material-pulling plate is provided on the outside of the screen cylinder;

[0009] The processing box is also equipped with a temporary storage cylinder, and one end of the screening cylinder is connected to the temporary storage cylinder through a connecting pipe; the bottom of the temporary storage cylinder is equipped with a discharge pipe, and the connecting hose is connected to the discharge pipe.

[0010] Preferably, a circumferential gap is formed between the rotating drum and the screening drum, and the material feeding plate is located within the circumferential gap.

[0011] Preferably, the feeding plate includes multiple feeding panels and multiple feeding mesh plates, with each feeding panel and each feeding mesh plate being equidistantly and spaced apart in the circumference of the rotating drum.

[0012] Preferably, a second fin is provided inside the rotating drum at one end close to the inflow pipe, and the second fin is multiple and equidistantly spaced.

[0013] Preferably, one end of the connecting pipe is tangent to the bottom of the screening cylinder, and the other end is connected to the top of the temporary storage cylinder.

[0014] Preferably, an internal disperser is provided inside the discharge pipe. The internal disperser includes a front disperser and a rear disperser. The rear disperser is disposed close to the temporary storage cylinder, and the front disperser is disposed close to the connecting hose.

[0015] Preferably, the pre-dispersant includes an alloy steel wire, which has a first connecting end and a second connecting end. The alloy steel wire is coiled around the first connecting end as a base point toward the second connecting end to form a plurality of spiral coils, and each spiral coil gradually decreases in size from the first connecting end to the second connecting end. A first gap is formed between each spiral coil.

[0016] Preferably, the first connecting end is a fixed end, fixed on the rear diffuser, and the second connecting end is a free end, facing the connecting hose.

[0017] Preferably, the rear disperser includes a central cylinder, with a plurality of first fins distributed circumferentially around the central cylinder, and a second gap is formed between two adjacent first fins.

[0018] Preferably, the cross-section of each of the first fins is a continuous wavy shape.

[0019] The beneficial effects of this invention are as follows: By using the integrated powder screening machine provided by this invention, compared with the prior art, before the material enters the temporary storage cylinder after being crushed, the rotating feeding screen and feeding panel disperse and push the material. The material passes through the mesh of the feeding screen, achieving loosening treatment of the material and shaping it in a dispersed state. This effectively prevents the agglomeration phenomenon caused by continuous accumulation of material after it is directly crushed and stored in the temporary storage cylinder. At the same time, when the vacuum feeder sucks the material in the temporary storage cylinder into the vibrating screen, it longitudinally divides the material through multiple first fins, allowing the material to flow out smoothly in the second gap. Simultaneously, the spiral alloy steel wire generates a vibrating motion during the material flow, causing the cross-section of the material to be circumferentially divided into a loose state when it flows out of the first gap, further ensuring the looseness of the material.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation schemes as long as the effects of the present invention can be achieved.

[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0031] Reference Figure 1-7 This implementation plan describes one type of integrated powder screening machine.

[0032] like Figure 1 As shown, the integrated powder screening machine includes a crusher 1 and a vibrating screen 5. The outlet end of the crusher 1 is connected to a processing box 3 via an inflow pipe 2. A vacuum suction pump 4 is installed on the top of the vibrating screen 5, and the inlet end of the vacuum suction pump 4 is connected to the processing box 3 via a connecting hose 6. Before entering the vibrating screen 5, the material crushed by the crusher 1 first enters the processing box 3 for dispersion treatment. The dispersed material is then sucked into the vibrating screen 5 by the vacuum suction pump 4 for vibration screening.

[0033] like Figure 2 As shown, a screening cylinder 8 is installed inside the processing box 3, and a rotating cylinder 9 is rotatably connected inside the screening cylinder 8. Multiple second fins 17 are installed inside the rotating cylinder 9 near the end of the inflow pipe 2, and these second fins 17 are equidistant and spaced apart. The material pulverized by the crusher 1 enters the rotating cylinder 9 inside the processing box 3 through the inflow pipe 2. During the entry process, the material is separated into multiple streams by the multiple second fins 17, entering the rotating cylinder 9 in a dispersed manner for screening and pre-dispersion treatment.

[0034] like Figure 3 As shown, one end of the rotating drum 9 is an open end, which is rotatably connected to the inflow pipe 2; the other end of the rotating drum 9 is a closed end, and a motor 15 is fixed to the outside of the processing box 3. The output end of the motor 15 passes through the outer wall of the processing box 3 and is fixed to the closed end of the rotating drum 9. The motor 15 drives the rotating drum 9 to rotate on the inflow pipe 2 and the screening drum 8.

[0035] like Figure 2 As shown, the portion of the rotating drum 9 located inside the screening drum 8 is equipped with a screen cylinder 13, and a material-pushing plate is provided on the outer side of the screen cylinder 13. A circumferential gap is formed between the rotating drum 9 and the screening drum 8, and the material-pushing plate is located within the circumferential gap. When the rotating drum 9 is driven to rotate forward by the motor 15, the material inside the rotating drum 9 falls into the circumferential gap in a dispersed manner after passing through the screen cylinder 13; at the same time, as the rotating drum 9 rotates, the material-pushing plate pushes the material in the circumferential gap into the connecting pipe 12, and then into the temporary storage cylinder 7 through the connecting pipe 12.

[0036] like Figure 3 and Figure 4 As shown, the feeding plate includes multiple feeding panels 14 and multiple feeding mesh plates 16. Each feeding panel 14 and each feeding mesh plate 16 are equidistantly and spaced apart in the circumference of the rotating drum 9. The feeding plate is designed in two forms: feeding panels 14 and feeding mesh plates 16. The feeding panel 14 is a single panel used to push the material into the connecting pipe 12. The feeding mesh plate 16 is a metal mesh plate. When the rotating drum 9 rotates, the feeding mesh plate 16 contacts the material in the circumferential gap. At this time, the material passes through the mesh of the feeding mesh plate 16, which loosens the material. The loosened material is then pushed into the connecting pipe 12 through the feeding panel 14.

[0037] like Figure 2 As shown, a temporary storage cylinder 7 is also provided inside the processing box 3. One end of the screening cylinder 8 is connected to the temporary storage cylinder 7 through a connecting pipe 12. A discharge pipe 10 is provided at the bottom of the temporary storage cylinder 7, and a connecting hose 6 is connected to the discharge pipe 10.

[0038] In this embodiment, since the material after being crushed by the crusher 1 has heat on its surface, it is rotated and dispersed in the rotating drum 9. When the material is dispersed and pushed by the rotating feed screen 16 and feed panel 14, the material can be effectively shaped in a dispersed state. The material is then stored in the temporary storage cylinder 7 after being dispersed and shaped, which effectively prevents the agglomeration phenomenon caused by continuous accumulation of the material after it is directly crushed and stored in the temporary storage cylinder 7.

[0039] like Figure 2 As shown, the connecting pipe 12 is inclined, with one end tangent to the bottom of the screening cylinder 8 and the other end connected to the top of the temporary storage cylinder 7. By adopting the inclined setting, the material can be pushed out directly into the temporary storage cylinder 7 after being pushed by the feeding panel 14.

[0040] In one implementation, such as Figure 2 and Figure 5 As shown, an internal disperser 11 is installed inside the discharge pipe 10. The internal disperser includes a front disperser 111 and a rear disperser 112. The rear disperser 112 is located close to the temporary storage cylinder 7, and the front disperser 111 is located close to the connecting hose 6. When the vacuum suction pump 4 draws material from the temporary storage cylinder 7 through the connecting hose 6, the material enters the connecting hose 6 through the internal disperser 11 inside the discharge pipe 10, thus dispersing the material accumulated in the temporary storage cylinder 7 during suction. This dispersed material is then drawn into the vibrating screen 5 by the vacuum suction pump 4.

[0041] Specifically, the post-disperser 112 includes a central cylinder 112a, with multiple first fins 112b distributed circumferentially around the central cylinder 112a, and a second gap 112c formed between adjacent first fins 112b. The cross-section of each first fin 112b is a continuous wavy shape. When the material flows into the discharge pipe 10, it first contacts the post-disperser 112, and after being divided by the multiple first fins 112b, the material enters the second gap 112c and flows out, thus longitudinally dividing the material.

[0042] The pre-dispersant 111 includes an alloy steel wire, which includes a first connecting end 111a and a second connecting end 111b. The alloy steel wire is coiled around the first connecting end 111a as a base point toward the second connecting end 111b to form several spiral coils, and each spiral coil gradually decreases in size from the first connecting end 111a toward the second connecting end 111b. A first gap 111c is formed between each spiral coil.

[0043] The first connecting end 111a is a fixed end, fixed to the rear disperser 112, and the second connecting end 111b is a free end, facing the connecting hose 6. When the material passes through the front disperser 111, it flows from the first connecting end 111a to the second connecting end 111b and then flows out through the first gap 111c between each spiral coil. The spiral alloy steel wire is stretched by the flow of the material, causing the spacing of the first gap 111c to be continuously stretched and pulled back by its own elastic rebound force, resulting in continuous changes. This causes the spiral alloy steel wire to vibrate. When the material flows out of the first gap 111c, its cross-section is divided into loose pieces by the spiral alloy steel wire and enters the connecting hose 6.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
