DETAILED DESCRIPTION

[0017] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example like Figures 1 to 10 As shown, the present invention provides a feeding structure for high-viscosity mineral processing agent raw materials, comprising a mixing box 1 and a box cover 2 arranged on the top of the mixing box 1, the box cover 2 is provided with a mixing device 3 extending into the interior of the mixing box 1; a plurality of feeding pipes 4 connected with the bottom of the box cover 2 are provided on the top of the box cover 2, and the feeding pipes 4 can heat the raw materials; a rotating extrusion structure 5 and a plurality of axial movement structures 6 respectively extending into the corresponding feeding pipes 4 are provided at the bottom of the box cover 2, and the rotating extrusion structure 5 synchronously extrude the plurality of axial movement structures 6 along the axial movement of the feeding pipe 4; each axial movement structure 6 is rotatably connected to a circumferential downward feeding structure 7, and each circumferential downward feeding structure 7 rotates around the axis of the corresponding feeding pipe 4; each circumferential downward feeding structure 7 is provided with a guide structure 8 connected to the inner wall of the corresponding feeding pipe 4, and the guide structure 8 is used to guide the circumferential downward feeding structure 7 to rotate when moving upward.

[0019] In actual application of the present invention, raw materials can be added to the mixing box 1 through multiple feed pipes 4, avoiding the problem of being unable to add materials after one feed pipe 4 is blocked; when the mixed raw materials are added through the feed pipe 4, the feed pipe 4 heats the raw materials to avoid the raw materials condensing and blocking the feed pipe 4. The way in which the feed pipe 4 heats the raw materials is the existing technology, such as directly setting a heating element on the outer wall or inner wall of the feed pipe 4, etc., which will not be described in detail.

[0020] In the process of raw materials passing through the feed pipe 4 and entering the mixing box 1, the rotating extrusion structure 5 can drive multiple axial motion structures 6 to move up and down along the axial direction of the feed pipe 4, thereby driving multiple circumferential downward feeding structures 7 to move up and down; at the same time, the guide structure 8 can guide the circumferential downward feeding structure 7 to rotate around the axis of the corresponding feed pipe 4 to a preset angle (the preset angle is set as needed, such as 30° or 45°, etc.) when the circumferential downward feeding structure 7 moves upward. When the circumferential downward feeding structure 7 moves downward, the raw materials in the feed pipe 4 are squeezed downward, so that the raw materials flow into the mixing box 1 and provide an additional driving force for the flow of the raw materials, thereby avoiding the problem that the raw materials adhere to the bottom of the feed pipe 4, causing the feed pipe 4 to be blocked, and the feeding efficiency is affected by the adhesion of the raw materials. The position of the circumferential downward feeding structure 7 pressing the raw materials will change many times during the rotation process, so that the raw materials in the feed pipe 4 can all be pressed downward, further improving the pushing effect on the raw materials.

[0021] In this embodiment, the mixing device 3 is used to stir the raw materials in the mixing box 1, which is a prior art and will not be elaborated in detail here.

[0022] As an embodiment of the present invention, the rotary extrusion structure 5 includes an annular plate 501 fixedly connected to the bottom of the box cover 2, an annular outer tooth plate 502 is rotatably connected to the inner wall of the annular plate 501, a plurality of extrusion blocks 503 are evenly arranged on the inner wall of the annular outer tooth plate 502, a transmission gear 504 is meshed on the outer wall of the annular outer tooth plate 502, a mounting plate 505 is arranged on the inner wall of the box cover 2, the mounting plate 505 is located above the transmission gear 504, the center of the transmission gear 504 is connected to a driving device through a rotating shaft, and the driving device is installed on the top of the mounting plate 505.

[0023] A rotating groove rotatably connected to the annular outer tooth plate 502 is provided on the inner wall of the annular plate 501, a cover plate 507 connected to the inner wall of the box cover 2 is provided on the outer wall of the annular plate 501, and the driving device, transmission gear 504 and mounting plate 505 are all located inside the cover plate 507.

[0024] When the rotating extrusion structure 5 is working, the driving device drives the rotating shaft and drives the transmission gear 504 to rotate. The transmission gear 504 drives the annular outer tooth plate 502 to rotate, so that the multiple extrusion blocks 503 on the annular outer tooth plate 502 sequentially and cyclically extrude the axial motion structure 6, so that the axial motion structure 6 can cyclically move up and down, thereby continuously driving the circumferential feeding structure 7 to move up and down.

[0025] In this embodiment, the driving device may be a motor or other device capable of driving the rotating shaft to rotate. The driving device is a prior art and will not be elaborated in detail here.

[0026] The cover plate 507 can prevent the raw material from splashing onto the transmission gear 504 , and the rotating groove is used to prevent the raw material from falling onto the tooth surface of the annular outer tooth plate 502 , thereby ensuring the normal operation of the rotary extrusion structure 5 .

[0027] The axial motion structure 6 includes a connecting plate 601 connected to the bottom of the box cover 2, and the bottom of the connecting plate 601 is connected to a straight tube 602 coaxial with the corresponding feed tube 4, and the top of the straight tube 602 is slidably and sealedly sleeved with a movable tube 603, and the top of the movable tube 603 is closed; the bottom of the movable tube 603 is connected to a transverse tube 604, and the transverse tube 604 is arranged along the radial direction of the annular plate 501; a sliding column 605 is slidably and sealedly sleeved inside the transverse tube 604, and a hemispherical plate 606 is arranged at the end of the sliding column 605 away from the transverse tube 604, and the spherical surface of the hemispherical plate 606 abuts against the inner wall of the annular outer tooth plate 502; a compression spring 607 is sleeved on the sliding column 605, and the two ends of the compression spring 607 abut against the end of the transverse tube 604 and one side of the hemispherical plate 606 respectively.

[0028] A shield plate 608 is provided at the bottom of the connecting plate 601, and the shield plate 608 is located directly above the transverse tube 604; the straight tube 602 is fixedly mounted on the shield plate 608 and passes through the shield plate 608; two guiding slopes 609 are symmetrically provided on the top of the shield plate 608, and the tops of the two guiding slopes 609 intersect.

[0029] When the axial motion structure 6 is squeezed by the squeezing block 503, the spherical surface of the hemispherical plate 606 contacts the squeezing block 503, and the spherical surface of the hemispherical plate 606 guides the squeezing block 503, so that the squeezing block 503 gradually squeezes the hemispherical plate 606, so that the hemispherical plate 606 drives the sliding column 605 to move into the transverse tube 604. At the same time, the compression spring 607 is further compressed. Since the sliding column 605 seals one end of the transverse tube 604, the other end of the transverse tube 604 is connected to one end of the straight tube 602, and the other end of the straight tube 602 is sealed by the movable tube 603, therefore, in the process of the sliding column 605 moving into the transverse tube 604, the sliding column 605 squeezes the internal gas of the transverse tube 604, thereby driving the movable tube 603 to move upward, and the movable tube 603 drives the circumferential downward material structure 7 to move upward.

[0030] After the hemispherical plate 606 is out of contact with the extrusion block 503, the hemispherical plate 606 is reset to abut against the inner wall of the annular outer tooth plate 502 under the elastic force of the compression spring 607, and the sliding column 605 is also reset synchronously. At the same time, the gas in the straight tube 602 and the horizontal tube 604 can be sucked to form a negative pressure, and the negative pressure and the self-weight of the circumferential downward material structure 7 can jointly drive the movable tube 603 to move downward, and the movable tube 603 drives the circumferential downward material structure 7 to move downward, so that the circumferential downward material structure 7 presses the raw material downward.

[0031] The shield plate 608 can prevent the raw material from dripping onto the transverse tube 604, the sliding column 605, the compression spring 607 and the hemispherical plate 606, thereby ensuring the normal movement of the axial motion structure 6. The two guiding inclined surfaces 609 can guide the raw material to flow to both sides of the transverse tube 604, accelerate the falling of the raw material, and prevent the raw material from condensing on the shield plate 608.

[0032] As an embodiment of the present invention, the circumferential downward feeding structure 7 includes a connecting shaft 701 rotatably connected to the top of the movable tube 603, and a plurality of fan blade seats 702 are arranged on the circumferential side of the connecting shaft 701, and the plurality of fan blade seats 702 are spirally arranged around the axis of the connecting shaft 701; each fan blade seat 702 is rotatably connected to a fan blade 703 through a first torsion spring, and a limiting plate 704 is arranged on each fan blade seat 702, and the limiting plate 704 is located above the fan blade 703. When the fan blade 703 is in a horizontal state, the top of the fan blade 703 abuts against the limiting plate 704.

[0033] When the movable tube 603 moves up and down, the connecting shaft 701 moves up and down synchronously. Specifically, when the connecting shaft 701 moves upward, the fan blade seat 702 drives the fan blade 703 to move upward. At this time, the fan blade 703 can rotate downward under the extrusion of the raw material to avoid the feed pipe 4 from being blocked.

[0034] When the connecting shaft 701 moves downward, due to the limitation of the limit plate 704, the fan blade 703 can rotate upward until it abuts against the limit plate 704 through the elastic force of the first torsion spring and the extrusion force of the raw material. Thereafter, the fan blade 703 no longer rotates, so that the fan blade 703 can press the raw material downward to flow.

[0035] In this embodiment, the lowest point where the lowest blade 703 can move is located below the feed pipe 4 , thereby ensuring that the raw materials are pressed into the mixing box 1 .

[0036] The guide structure 8 includes a guide rod 801 fixedly connected to the connecting shaft 701, and an annular baffle 802 is fixedly connected to the guide rod 801 and is in sliding and sealing contact with the inner wall of the feed pipe 4. A guide groove 803 is provided on the inner wall of the feed pipe 4, and the end of the guide rod 801 is slidably connected in the guide groove 803. When the straight tube 602 moves upward, the guide rod 801 moves upward along the guide groove 803; when the straight tube 602 moves downward, the guide rod 801 moves downward along the guide groove 803.

[0037] The guide groove 803 includes a plurality of vertical grooves 804 and a plurality of inclined grooves 805, and the plurality of vertical grooves 804 and the plurality of inclined grooves 805 are alternately arranged, and each vertical groove 804 is connected to two adjacent inclined grooves 805; the bottom of the inner top wall of each inclined groove 805 is rotatably connected to a one-way rotating plate 806 through a second torsion spring, and when the one-way rotating plate 806 is not in contact with the guide rod 801, the one-way rotating plate 806 abuts against the inner top wall of the inclined groove 805.

[0038] When the connecting shaft 701 moves upward, the guide rod 801 moves upward synchronously, and at the same time, the end of the guide rod 801 moves upward along the inclined groove 805, thereby driving the connecting shaft 701 to rotate and driving the annular baffle 802 to move; when the connecting shaft 701 moves downward, the guide rod 801 moves downward synchronously, and at the same time, the end of the guide rod 801 moves downward along the vertical groove 804 and limits the rotation of the connecting shaft 701, so that the fan blades 703 press the raw material downward.

[0039] When the guide rod 801 moves to the position where the bottom of the vertical groove 804 is connected to the inclined groove 805, the guide rod 801 squeezes the one-way rotating plate 806 and rotates the one-way rotating plate 806 until the guide rod 801 moves downward to disengage from the one-way rotating plate 806. At this time, the one-way rotating plate 806 is reset to abut against the inner top wall of the inclined groove 805 by the elastic force of the second torsion spring. When the connecting shaft 701 moves upward and drives the guide rod 801 to move, the guide rod 801 moves to contact the one-way rotating plate 806. The one-way rotating plate 806 restricts the guide rod 801 from moving upward along the vertical groove 804, so that the guide rod 801 can only move along the surface of the one-way rotating plate 806 to the inclined groove 805, thereby causing the connecting shaft 701 to rotate. The annular baffle 802 slides and fits with the inner wall of the feed pipe 4, which can restrict the raw materials from entering the guide groove 803.

[0040] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
