Description

Technical Field

[0001] The invention relates to the technical field of screw conveyors, in particular to a powder screw conveyor for anti-sticking materials. Background Art

[0002] Screw conveyor is a machine that uses a motor to drive the screw to rotate and push the material to achieve the conveying function. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation. Therefore, in the field of powder conveying, the main method is to use screw conveyors to continuously convey powdered materials over long distances.

[0003] When the existing screw conveyor conveys powder materials, the powder materials are dusty and when the powder materials fall, the dust will be raised upward, so that the dust accumulated at the bottom of the conveying cylinder is raised and then floats out from the feed pipe. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a powder screw conveyor for anti-sticking materials, comprising a conveying cylinder, the conveying cylinder is used for guiding and conveying powder materials, support frames are fixedly installed on both sides of the bottom of the conveying cylinder, and a discharge pipe is opened at the bottom of the conveying cylinder;

[0005] A spiral stirring member, which is used for stirring and conveying sticky powder materials, a motor is fixedly mounted on the outer surface of the spiral stirring member, and a fixing frame is fixedly mounted on the bottom of the motor;

[0006] A feeding assembly, which is used for dust-proof feeding of powder materials;

[0007] The feeding assembly is fixedly installed in the middle of the top of the conveying cylinder near the motor side, the motor is fixedly installed on the outer surface of the conveying cylinder through a fixing frame, the output end of the motor is fixedly connected to the spiral stirring piece, the spiral stirring piece is rotatably installed inside the cavity of the conveying cylinder, and the spiral stirring piece is adapted to the conveying cylinder; the staff starts the motor so that the output end of the motor drives the spiral stirring piece to rotate in the conveying cylinder. At this time, the staff introduces the powder material into the conveying cylinder through the feeding assembly, and the powder material moves in the conveying cylinder along with the rotating spiral stirring piece, and the powder material has been transported to the discharge pipe and discharged from the conveying cylinder through the discharge pipe.

[0008] The spiral stirring member includes an output shaft, a spiral blade is fixedly mounted on the outer surface of the output shaft, an anti-stuck dispersion member is sleeved on the outer surface of the output shaft, and a material-diverting member is fixedly mounted inside the anti-stuck dispersion member. The staff starts the motor so that the output end of the motor drives the output shaft to rotate, so as to drive the spiral blade to rotate and transport the powder material. The spiral blade and the anti-stuck dispersion member are arranged in a segmented shape to prevent the spiral blade from being interfered by the anti-stuck dispersion member when rotating.

[0009] Preferably, the output shaft is fixedly mounted on the output end of the motor, and the output shaft extends through the conveying cylinder to the interior thereof, the spiral blade is a segmented structure, the anti-stuck dispersion component is arranged between the opposite surfaces of the spiral blade, and the anti-stuck dispersion component is adapted to the interior of the conveying cylinder.

[0010] Preferably, the feeding assembly includes a feeding pipe, a guide ball is fixedly installed on the top of the feeding pipe, a guide port is opened on the top of the guide ball, and a dust reduction material receiving piece is fixedly installed at the connection between the guide ball and the feeding pipe. The staff guides the powder material into the guide ball along the guide port, and the inner wall of the guide ball is set as a smooth arc surface. After the powder material is introduced, it slides along the inner wall of the guide ball toward the feeding pipe. Since the powder material is a dusty material, the dust will be lifted upward when the powder material falls, so that the dust accumulated at the bottom of the conveying tube is lifted and floats out of the feeding pipe. Therefore, a dust reduction material receiving piece is provided at the connection between the feeding pipe and the guide ball to cushion the falling powder material, so as to reduce the impact force of the powder material when it falls.

[0011] Preferably, the feed pipe is fixedly mounted on the top of the conveying cylinder, the feed pipe is connected to the cavity of the conveying cylinder, and the dust-reducing material receiving piece is extruded and fitted with the inner wall of the feed pipe. The guide ball and the feed pipe are both arranged in an inclined shape, and the powder material is conveyed into the conveying cylinder along the inclined angle of the feed pipe when introduced, so that the impact force caused by the powder on the dust-reducing material receiving piece when it contacts with the dust-reducing material receiving piece changes due to the influence of the inclined angle.

[0012] Preferably, the dust reduction material receiving member comprises a segmented connecting ring, both ends of the segmented connecting ring are fixedly mounted with a clamping ring, and the outer surface of the segmented connecting ring is fixedly mounted with an inner extrusion sheet through the clamping ring. After the powder material is introduced into the material guide ball, it slides downward along the inner wall of the material guide ball and slides to the surface of the curved pad. At this time, the powder material sliding downward squeezes the curved pad, causing the curved sheet to sag downward and abut against the inner extrusion sheet, thereby providing preliminary buffering for the powder material through the curved sheet, preventing the powder material from directly sliding into the conveying tube during introduction, causing toxic dust to fly and causing harm to the staff.

[0013] Preferably, the inner extrusion sheet and the outer surface of the segmented connecting ring are sleeved with a bent pad, and a curved arc sheet is fixedly installed on the side of the bent pad close to the inner extrusion sheet, and the curved arc sheet is extruded and adapted with the inner extrusion sheet. After the dust material is buffered and limited by the bent pad, it continues to slide into the feed pipe. At this time, the powder material contacts the connecting sheet. There are four connecting sheets, which are evenly distributed in the feed pipe to separate the inner cavity of the feed pipe. When the powder material slides down, the powder material is dispersed, so that when the powder material falls to the bottom of the conveying tube, it is separated by the connecting sheet to form multiple falling points, thereby avoiding the raw materials from falling from the same position in the conveying tube and piling up too high, causing the feed pipe to be blocked, affecting the material guiding speed.

[0014] Preferably, a connecting piece is fixedly installed on the surface of the bending pad on one side away from the bending arc piece, and the connecting piece is fixedly installed at the connection between the guide ball and the feed pipe.

[0015] Preferably, the anti-stuck dispersion member includes a fixed set, the outer surface of the fixed set is fixedly mounted with support bars, the support bars are circumferentially distributed on the outer surface of the fixed set, and the outer surface of the support bars is fixedly mounted with positioning rings. During the powder raw material conveying process, the output shaft drives the fixed set to rotate, and drives the support bars, the material-dispensing member and the positioning ring to rotate through the fixed set, so that the material-dispensing member can break up the clumped materials when rotating, so as to prevent the powder raw materials from clumping and sticking to the conveying cylinder and the spiral blades.

[0016] Preferably, the fixing kit is rotatably mounted on the outer surface of the output shaft, the positioning ring is matched with the inner wall of the conveying cylinder, and the positioning ring is rotatably mounted on the inner wall of the conveying cylinder.

[0017] Preferably, the material-digging member comprises a clamping block, and rotating rods are fixedly installed on both sides of the outer surface of the clamping block, and the rotating rods are rotatably installed inside the support bar. A material-digging sheet is fixedly installed on the surface of the clamping block close to the feeding component, and a protruding block is provided on the surface of the clamping block away from the material-digging sheet. When the support bar drives the clamping block to rotate with the output shaft, the material-digging sheet contacts the powder material conveyed by the spiral blade and disperses and stirs the powder raw material. When encountering a hard material, the material-digging sheet and the material are moved and the clamping block is driven to rotate in the support bar through the rotating rod to avoid jamming when the material-digging sheet breaks up the material.

[0018] The present invention provides a powder screw conveyor for anti-sticking materials. It has the following beneficial effects:

[0019] 1. The powder screw conveyor of the anti-sticking material, after the powder material is introduced into the guide ball, slides downward along the inner wall of the guide ball and slides to the surface of the curved pad. At this time, the powder material sliding downward squeezes the curved pad, causing the curved sheet to sink downward and abut against the inner squeezing sheet, thereby providing preliminary buffering for the powder material through the curved sheet, preventing the powder material from directly sliding into the conveying barrel during introduction, causing toxic dust to fly and causing harm to the workers.

[0020] 2. The powder screw conveyor of the anti-sticking material, after the powder material is buffered and limited by the bending pad, continues to slide into the feed pipe. At this time, the powder material contacts the receiving piece. There are four receiving pieces, which are evenly distributed in the feed pipe to separate the inner cavity of the feed pipe. The powder material is dispersed when it slides down, so that the powder material is separated by the receiving pieces to form multiple falling points when it falls to the bottom of the conveying cylinder, thereby preventing the raw materials from falling from the same position in the conveying cylinder and piling up too high to cause the feed pipe to be blocked, affecting the material guiding speed.

[0021] 3. The anti-sticking powder screw conveyor drives the fixed kit to rotate through the output shaft during the powder raw material conveying process, and drives the support bar, the material shifting piece and the positioning ring to rotate through the fixed kit, so that the material that is stuck together can be broken up when the material shifting piece rotates, so as to prevent the powder raw materials from clumping and sticking to the conveying cylinder and the spiral blades.

[0022] Fourth, the powder screw conveyor of the anti-sticking material is arranged in an inclined shape by setting the guide ball and the feed pipe. When the powder material is introduced, it is conveyed into the conveying cylinder along the inclined angle of the feed pipe, so that the impact force caused by the powder on the dust reduction receiving part when it contacts the dust reduction receiving part is affected by the inclined angle.

[0023] 5. The powder screw conveyor of the anti-sticking material drives the clamping block through the support bar to rotate with the output shaft, and the material-pickling piece contacts the powder material conveyed by the spiral blade and disperses and stirs the powder raw material. When encountering harder materials, the material-pickling piece and the material are moved and the clamping block is driven to rotate in the support bar through the rotating rod to avoid jamming when the material-pickling piece breaks up the material.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0034] The first embodiment, as Figures 1 to 3 As shown, the present invention provides a technical solution: a powder screw conveyor for anti-sticking materials, comprising a conveying cylinder 1, the conveying cylinder 1 is used for guiding and conveying powder materials, support frames 6 are fixedly installed on both sides of the bottom of the conveying cylinder 1, and a discharge pipe 7 is opened at the bottom of the conveying cylinder 1;

[0035] A spiral stirring member 3, which is used for stirring and conveying sticky powder materials. A motor 4 is fixedly mounted on the outer surface of the spiral stirring member 3, and a fixing frame 5 is fixedly mounted on the bottom of the motor 4;

[0036] A feeding assembly 2, which is used for dust-proof feeding of powder materials;

[0037] The feeding assembly 2 is fixedly mounted at the middle of the top of the conveying cylinder 1 near the motor 4, and the motor 4 is fixedly mounted on the outer surface of the conveying cylinder 1 through a fixing frame 5. The output end of the motor 4 is fixedly connected to the spiral stirring piece 3, and the spiral stirring piece 3 is rotatably mounted inside the cavity of the conveying cylinder 1, and the spiral stirring piece 3 is adapted to the conveying cylinder 1; the staff starts the motor 4 so that the output end of the motor 4 drives the spiral stirring piece 3 to rotate in the conveying cylinder 1. At this time, the staff introduces the powder material into the conveying cylinder 1 through the feeding assembly 2, and the powder material moves in the conveying cylinder 1 along with the rotating spiral stirring piece 3, and the powder material has been transported to the discharge pipe 7 and discharged from the conveying cylinder 1 through the discharge pipe 7.

[0038] The spiral stirring member 3 includes an output shaft 33, a spiral blade 31 is fixedly mounted on the outer surface of the output shaft 33, an anti-stuck dispersion member 32 is sleeved on the outer surface of the output shaft 33, and a material-dispensing member 34 is fixedly mounted inside the anti-stuck dispersion member 32. The staff starts the motor 4 so that the output end of the motor 4 drives the output shaft 33 to rotate, so as to drive the spiral blade 31 to rotate and convey the powder material. The spiral blade 31 and the anti-stuck dispersion member 32 are arranged in a segmented shape to prevent the spiral blade 31 from being interfered by the anti-stuck dispersion member 32 when rotating.

[0039] The output shaft 33 is fixedly mounted on the output end of the motor 4 , and the output shaft 33 passes through the conveying cylinder 1 and extends into the interior thereof. The spiral blade 31 is a segmented structure, and the anti-stuck dispersion component 32 is arranged between the opposite surfaces of the spiral blade 31 , and the anti-stuck dispersion component 32 is adapted to the interior of the conveying cylinder 1 .

[0040] The second embodiment is based on the first embodiment. Figures 4 to 5 As shown, preferably, the anti-stuck dispersion member 32 includes a fixing kit 323, and a support bar 322 is fixedly installed on the outer surface of the fixing kit 323. The support bars 322 are distributed in a circumferential shape on the outer surface of the fixing kit 323, and a positioning ring 321 is fixedly installed on the outer surface of the support bars 322. During the conveying of the powder raw material, the output shaft 33 drives the fixing kit 323 to rotate, and drives the support bar 322, the material-dispensing member 34 and the positioning ring 321 to rotate through the fixing kit 323, so that the material-dispensing member 34 can break up the clumped materials when rotating, so as to prevent the powder raw materials from clumping and sticking to the conveying cylinder 1 and the spiral blade 31.

[0041] Preferably, the fixing kit 323 is rotatably mounted on the outer surface of the output shaft 33 , the positioning ring 321 is matched with the inner wall of the conveying cylinder 1 , and the positioning ring 321 is rotatably mounted on the inner wall of the conveying cylinder 1 .

[0042] Preferably, the material-digging member 34 comprises a clamping block 342, and rotating rods 344 are fixedly installed on both sides of the outer surface of the clamping block 342, and the rotating rods 344 are rotatably installed inside the support bar 322. A material-digging piece 343 is fixedly installed on the surface of the clamping block 342 close to the feeding assembly 2, and a protruding block 341 is provided on the surface of the clamping block 342 away from the material-digging piece 343. When the support bar 322 drives the clamping block 342 to rotate along with the output shaft 33, the material-digging piece 343 contacts the powder material conveyed by the spiral blade 31, and disperses and stirs the powder raw material. When encountering a hard material with agglomeration, the material-digging piece 343 and the material are moved, and the clamping block 342 is driven to rotate in the support bar 322 through the rotating rod 344, so as to avoid the jamming phenomenon when the material-digging piece 343 breaks up the material.

[0043] The third embodiment is based on the first and second embodiments. Figures 6 to 8 As shown, the feeding assembly 2 includes a feed pipe 23, a guide ball 21 is fixedly installed on the top of the feed pipe 23, a guide port 24 is opened on the top of the guide ball 21, and a dust-reducing material receiving piece 22 is fixedly installed at the connection between the guide ball 21 and the feed pipe 23. The staff introduces the powder material into the guide ball 21 along the guide port 24, and the inner wall of the guide ball 21 is set as a smooth arc surface. After the powder material is introduced, it slides along the inner wall of the guide ball 21 toward the feed pipe 23. Since the powder material is a dusty material, the dust will be lifted upward when the powder material falls, so that the dust accumulated at the bottom of the conveying cylinder 1 is lifted and floats out from the feed pipe 23. Therefore, a dust-reducing material receiving piece 22 is provided at the connection between the feed pipe 23 and the guide ball 21 to cushion the falling powder material, so as to reduce the impact force of the powder material when it falls.

[0044] Preferably, the feed pipe 23 is fixedly mounted on the top of the conveying cylinder 1, the feed pipe 23 is connected to the cavity of the conveying cylinder 1, and the dust-reducing material receiving piece 22 is extruded and adapted to the inner wall of the feed pipe 23. The guide ball 21 and the feed pipe 23 are both arranged to be inclined, and the powder material is conveyed into the conveying cylinder 1 along the inclined angle of the feed pipe 23 when introduced, so that the impact force caused by the powder on the dust-reducing material receiving piece 22 when it contacts with the dust-reducing material receiving piece 22 is affected by the inclined angle and changes.

[0045] Preferably, the dust-reducing material receiving member 22 comprises a segmented connecting ring 221, and both ends of the segmented connecting ring 221 are fixedly mounted with a clamping ring 222, and the outer surface of the segmented connecting ring 221 is fixedly mounted with an inner extrusion sheet 224 through the clamping ring 222. After the powder material is introduced into the guide ball 21, it slides downward along the inner wall of the guide ball 21 and slides to the surface of the curved pad 226. At this time, the powder material sliding downward squeezes the curved pad 226, so that the curved sheet 225 is concave downward and abuts against the inner extrusion sheet 224, so that the powder material is initially buffered by the curved sheet 225, so as to prevent the powder material from directly sliding into the conveying tube 1 when being introduced, causing toxic dust to fly and causing harm to the staff.

[0046] Preferably, the inner extrusion sheet 224 and the outer surface of the segmented connecting ring 221 are sleeved with a bent pad 226, and a curved arc sheet 225 is fixedly installed on the side of the curved pad 226 close to the inner extrusion sheet 224, and the curved arc sheet 225 is extruded and adapted with the inner extrusion sheet 224. After being buffered and limited by the bent pad 226, the dust material continues to slide into the feed pipe 23. At this time, the powder material contacts the material receiving sheet 223. There are four material receiving sheets 223, which are evenly distributed in the feed pipe 23 to separate the inner cavity of the feed pipe 23, and disperse the powder material when it slides down, so that when the powder material falls to the bottom of the conveying tube 1, it is separated by the material receiving sheet 223 to form multiple falling points, thereby preventing the raw materials from falling from the same position in the conveying tube 1 and piling up too high to cause the feed pipe 23 to be blocked, affecting the material guiding speed.

[0047] Preferably, a connecting piece 223 is fixedly installed on the surface of the bending pad 226 away from the curved piece 225 , and the connecting piece 223 is fixedly installed at the connection between the guide ball 21 and the feed pipe 23 .

[0048] When in use, the staff starts the motor 4 so that the output end of the motor 4 drives the spiral stirring element 3 to rotate in the conveying barrel 1. At this time, the staff introduces the powder material into the conveying barrel 1 through the feeding assembly 2. The powder material moves in the conveying barrel 1 along with the rotating spiral stirring element 3. The powder material is transported to the discharge pipe 7 and discharged from the conveying barrel 1 through the discharge pipe 7.

[0049] The staff starts the motor 4 so that the output end of the motor 4 drives the output shaft 33 to rotate, thereby driving the spiral blade 31 to rotate to convey the powder material. The spiral blade 31 and the anti-stuck dispersion member 32 are configured in a segmented shape to prevent the spiral blade 31 from being interfered by the anti-stuck dispersion member 32 when rotating.

[0050] The staff guides the powder material into the guide ball 21 along the guide port 24. The inner wall of the guide ball 21 is set to a smooth arc surface. After the powder material is introduced, it slides along the inner wall of the guide ball 21 toward the feed pipe 23. Since the powder material is dusty, the dust will be lifted upward when the powder material falls, so that the dust accumulated at the bottom of the conveying cylinder 1 will float out from the feed pipe 23. Therefore, a dust reduction receiving piece 22 is provided at the connection between the feed pipe 23 and the guide ball 21 to cushion the falling powder material, so as to reduce the impact force of the powder material when it falls.

[0051] The guide ball 21 and the feed pipe 23 are both arranged to be inclined. When the powder material is introduced, it is conveyed into the conveying cylinder 1 along the inclined angle of the feed pipe 23, so that the impact force caused by the powder on the dust reduction receiving piece 22 when it contacts the dust reduction receiving piece 22 is affected by the inclined angle and changes.

[0052] After the powder material is introduced into the guide ball 21, it slides downward along the inner wall of the guide ball 21 and slides to the surface of the curved pad 226. At this time, the powder material sliding downward squeezes the curved pad 226, causing the curved sheet 225 to be concave downward and abut against the inner squeezing sheet 224, thereby providing preliminary buffering for the powder material through the curved sheet 225, thereby preventing the powder material from directly sliding into the conveying tube 1 during introduction, causing toxic dust to fly and causing harm to the staff.

[0053] After the dust material is buffered and limited by the bending pad 226, it continues to slide into the feed pipe 23. At this time, the powder material contacts the receiving piece 223. There are four receiving pieces 223, which are evenly distributed on the feed pipe 23 to separate the inner cavity of the feed pipe 23. When the powder material slides down, the powder material is dispersed so that when the powder material falls to the bottom of the conveying cylinder 1, it is separated by the receiving piece 223 to form multiple falling points, thereby preventing the raw materials from falling from the same position in the conveying cylinder 1 and piling up too high, causing the feed pipe 23 to be blocked, affecting the material guiding speed.

[0054] During the powder raw material conveying process, the output shaft 33 will drive the fixing kit 323 to rotate, and through the fixing kit 323, the support bar 322, the material shifting member 34 and the positioning ring 321 will rotate, so that when the material shifting member 34 rotates, the sticky materials are broken up to prevent the powder raw materials from clumping and sticking to the conveying cylinder 1 and the spiral blades 31.

[0055] When the support bar 322 drives the clamping block 342 to rotate with the output shaft 33, the material-prying piece 343 comes into contact with the powder material conveyed by the spiral blade 31 and disperses and stirs the powder raw material. When encountering harder agglomerated materials, the material-prying piece 343 and the material are moved to drive the clamping block 342 to rotate in the support bar 322 through the rotating rod 344 to avoid jamming when the material-prying piece 343 breaks up the material.

[0056] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
