Description

Technical Field

[0001] The invention relates to the technical field of material screening, and in particular to a powder screening integrated machine. Background Art

[0002] With the continuous improvement of the degree of automation in industrial production, the application of integrated powder screening machines in various industries is becoming more and more extensive. After the existing integrated powder screening machines crush the materials, they usually directly put the crushed materials into stainless steel barrels for standby use. However, in actual application, this processing method has certain disadvantages.

[0003] On the one hand, some materials contain a certain amount of moisture. During the crushing process, the material itself will heat up due to friction and shearing. This kind of material is directly piled in a stainless steel barrel after being crushed, which is easy to cause agglomeration. On the other hand, the agglomerated material needs to be sucked into the oscillating screen by a vacuum feeder for screening during subsequent use. However, during the suction and oscillation screening process, some agglomerates cannot be sucked in or dispersed, resulting in production line interruption.

[0004] To solve this problem, enterprises usually need to manually open the equipment to crush the agglomerated materials, which not only increases production costs but also reduces production efficiency. Therefore, how to solve the agglomeration problem of the powder-screening machine in the process of crushing materials and improve material processing efficiency has become an urgent problem to be solved in the current field of powder-screening machines. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an integrated powder and screen machine, which solves the problem that the existing materials are prone to agglomeration when stored after being crushed.

[0011] Preferably, the material diverting plate comprises a plurality of material diverting panels and a plurality of material diverting mesh plates, and each of the material diverting panels and each of the material diverting mesh plates are equidistantly and spaced apart from each other in the circumferential direction of the rotating drum.

[0012] Preferably, a second fin is provided inside the drum at one end close to the inflow pipe, and the second fin is in plurality and is equidistant and spaced apart.

[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 in the discharge pipe, and the internal disperser includes a front disperser and a rear disperser, the rear disperser is provided close to the temporary storage tube, and the front disperser is provided close to the connecting hose.

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

[0019] Beneficial effects of the present invention: By using the powder screening machine provided by the present invention, compared with the prior art, before the material is crushed and enters the temporary storage tube, the rotating material-dividing mesh plate and the material-dividing panel disperse and push the material, and the material passes through the mesh holes of the material-dividing mesh plate, thereby realizing the loosening of the material, so that the material is shaped in a dispersed state, and effectively preventing the agglomeration phenomenon caused by continuous accumulation when the material is directly crushed and then enters the temporary storage tube for storage.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the implementation scheme.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0031] Reference Figure 1-7 A powder sieving integrated machine according to this embodiment is described.

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

[0033] like Figure 2 As shown, a screening drum 8 is provided in the processing box 3, a rotating drum 9 is rotatably connected in the screening drum 8, a second fin 17 is provided in the rotating drum 9 at one end close to the inflow pipe 2, and the second fins 17 are multiple and equidistant and spaced. The material crushed by the pulverizer 1 enters the rotating drum 9 in the processing box 3 through the inflow pipe 2, and during the entering process, the material is separated into multiple strands by the multiple second fins 17, and enters the rotating drum 9 in a dispersed state for screening and pre-dispersion treatment.

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

[0035] like Figure 2 As shown, the part of the drum 9 located inside the screening drum 8 is provided with a mesh drum 13, and a material-dispensing plate is provided outside the mesh drum 13. A circumferential gap is formed between the drum 9 and the screening drum 8, and the material-dispensing plate is located inside the circumferential gap. When the drum 9 is driven by the motor 15 and rotates forward, the material inside the drum 9 passes through the mesh drum 13 and falls into the circumferential gap in a dispersed state; at the same time, when the drum 9 rotates, the material-dispensing plate dispenses the material in the circumferential gap into the connecting pipe 12, and enters the temporary storage drum 7 through the connecting pipe 12.

[0036] like Figure 3 and Figure 4 As shown, the material-diverting plate includes a plurality of material-diverting panels 14 and a plurality of material-diverting mesh plates 16, each of which is equidistantly and spaced apart from the circumference of the drum 9. The material-diverting plate is designed in two forms: the material-diverting panel 14 and the material-diverting mesh plate 16, wherein the material-diverting panel 14 is a whole panel, used to push the material into the connecting pipe 12; the material-diverting mesh plate 16 is a metal mesh plate, and when the drum 9 rotates, the material-diverting mesh plate 16 contacts the material in the circumferential gap, and at this time, the material passes through the mesh of the material-diverting mesh plate 16 to loosen the material, and the loosened material is then pushed into the connecting pipe 12 through the material-diverting panel 14.

[0037] like Figure 2 As shown, a temporary storage cylinder 7 is also provided in the processing box 3 , and 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 when it falls into the rotating drum 9, and is dispersed and pushed by the rotating material-dispensing mesh plate 16 and the material-dispensing panel 14, which can effectively shape the material in a dispersed state, so that the material can enter the temporary storage tube 7 for storage after being dispersed and shaped, effectively preventing the agglomeration phenomenon caused by continuous accumulation when the material is directly crushed and then stored in the temporary storage tube 7.

[0039] like Figure 2 As shown, the connecting pipe 12 is tilted, one end is tangent to the bottom of the screening drum 8, and the other end is connected to the top of the temporary storage drum 7. The tilted setting allows the material to be pushed by the material panel 14 and then directly pushed out of the bottom of the screening drum 8 and fall into the temporary storage drum 7.

[0040] In one embodiment, Figure 2 and Figure 5 As shown, an internal disperser 11 is provided in the discharge pipe 10, and the internal disperser includes a front disperser 111 and a rear disperser 112, the rear disperser 112 is provided close to the temporary storage barrel 7, and the front disperser 111 is provided close to the connecting hose 6. When the vacuum suction pump 4 sucks the material in the temporary storage barrel 7 through the connecting hose 6, the material enters the connecting hose 6 through the internal disperser 11 in the discharge pipe 10, so that the material accumulated in the temporary storage barrel 7 is dispersed when being sucked, and the material is sucked into the vibrating screen 5 by the vacuum suction pump 4 in a dispersed state.

[0041] Specifically, the rear disperser 112 includes a central tube 112a, and a plurality of first fins 112b are distributed around the circumference of the central tube 112a, and a second gap 112c is formed between two adjacent first fins 112b. The cross section of each first fin 112b is a continuous wave shape. When the material flows into the discharge pipe 10, it first contacts the rear disperser 112, and the material is divided by the plurality of first fins 112b and then flows out into the second gap 112c, so that the material is divided longitudinally.

[0042] The front disperser 111 includes an alloy steel wire, which includes a first connection end 111a and a second connection end 111b. The alloy steel wire is coiled from the first connection end 111a as a base point toward the second connection end 111b to form a plurality of spiral turns, and each spiral turn gradually decreases from the first connection end 111a toward the second connection end 111b; a first gap 111c is formed between each spiral turn.

[0043] The first connection end 111a is a fixed end, fixed on the rear disperser 112, and the second connection end 111b is a free end, arranged toward the connecting hose 6. When the material passes through the front disperser 111, it flows out through the first gap 111c between each spiral circle during the process of entering from the first connection end 111a to the second connection end 111b, and the spiral alloy steel wire is stretched by the flow of the material, so that the spacing of the first gap 111c is continuously stretched and pulled back by its own elastic pullback force to form a continuous change, and the spiral alloy steel wire is vibrated, and when the material flows out of the first gap 111c, its cross-section circumferential direction is divided into a loose state by the spiral alloy steel wire and enters the connecting hose 6.

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