Description

Technical Field

[0001] The present invention relates to the technical field of feeding, and particularly relates to a feeding structure for raw materials of high-viscosity ore dressing agents. Background Art

[0002] Ore dressing agents mainly refer to collectors, frothers, inhibitors, flocculants, regulators, and extractants, matrix improvers for extraction, diluents, etc. used in hydrometallurgy. The synthesis process of ore dressing agents is to mix several liquid raw materials together, generate chemical reactions, and finally form a powdery composite.

[0003] Since the mixed products of some ore dressing agents have the characteristics of non-uniform phase turbid liquid, unstable properties, and high viscosity, most flocculant solutions have high viscosity and are prone to block the feeding pipeline during addition. The utility model patent with the publication number CN209348600U discloses a feeding structure for raw materials of high-viscosity ore dressing agents, which can prevent the high-viscosity liquid raw materials from condensing and blocking the pipeline in the second feeding pipe and the meter through heating. However, this patent still has the following problems: By continuously heating the raw materials, the patent can ensure the fluidity of the raw materials themselves. However, during the process of the raw materials entering the tank from the feeding pipe, the raw materials still have high viscosity, which will result in a small rate of the raw materials and adhesion, affecting the feeding efficiency, and easily causing blockage at the connection between the feeding pipe and the tank. Summary of the Invention

[0029] 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 creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment

[0031] Such as Figures 1 to 10As shown in the figure, the present invention provides a feeding structure for raw materials of high-viscosity ore dressing reagents, which includes a mixing tank 1 and a tank cover 2 arranged on the top of the mixing tank 1. A mixing device 3 extending into the interior of the mixing tank 1 is arranged on the tank cover 2; a plurality of feeding pipes 4 communicating with the bottom of the tank cover 2 are arranged on the top of the tank cover 2, and the feeding pipes 4 can heat the raw materials; a rotary extrusion structure 5 and a plurality of axial movement structures 6 respectively extending into the corresponding feeding pipes 4 are arranged at the bottom of the tank cover 2, and the rotary extrusion structure 5 synchronously extrudes the plurality of axial movement structures 6 to move axially along the feeding pipes 4; a circumferential feeding structure 7 is rotatably connected to each axial movement structure 6, and each circumferential feeding structure 7 rotates around the axis of the corresponding feeding pipe 4; a guiding structure 8 connected to the inner wall of the corresponding feeding pipe 4 is arranged on each circumferential feeding structure 7, and the guiding structure 8 is used to guide the circumferential feeding structure 7 to rotate when moving upward.

[0032] When the present invention is actually applied, the raw materials can be added into the mixing tank 1 through a plurality of feeding pipes 4, avoiding the problem that feeding cannot be carried out after one feeding pipe 4 is blocked; when the mixed raw materials are added through the feeding pipes 4, the feeding pipes 4 heat the raw materials to avoid the raw materials from condensing and blocking the feeding pipes 4. The method of heating the raw materials by the feeding pipes 4 is a prior art, such as directly arranging heating elements on the outer wall or inner wall of the feeding pipes 4, etc., which will not be elaborated here.

[0033] During the process of the raw materials entering the mixing tank 1 through the feeding pipes 4, the rotary extrusion structure 5 can drive the plurality of axial movement structures 6 to move up and down axially along the feeding pipes 4, thereby driving the plurality of circumferential feeding structures 7 to move up and down; at the same time, the guiding structure 8 can guide the circumferential feeding structure 7 to rotate around the axis of the corresponding feeding pipe 4 to a preset angle (the preset angle is set as needed, such as 30° or 45°, etc.) when the circumferential feeding structure 7 moves upward. When the circumferential feeding structure 7 moves downward, the raw materials in the feeding pipes 4 are extruded downward, so that the raw materials flow into the mixing tank 1 and provide an additional driving force for the flow of the raw materials, avoiding the problems that the raw materials adhere to the bottom of the feeding pipes 4, resulting in blockage of the feeding pipes 4 and affecting the feeding efficiency due to the adhesion of the raw materials. The position where the circumferential feeding structure 7 presses the raw materials will change multiple times during the rotation process, so that the raw materials in the feeding pipes 4 can all be pressed downward, further improving the pushing effect on the raw materials.

[0034] In this embodiment, the mixing device 3 is used to stir the raw materials inside the mixing tank 1, which is a prior art and will not be elaborated here.

[0035] 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. A rotary outer toothed plate 502 is rotatably connected to the inner side wall of the annular plate 501. A plurality of extrusion blocks 503 are uniformly arranged on the inner side wall of the rotary outer toothed plate 502. A transmission gear 504 is engaged with the outer wall of the rotary outer toothed plate 502. An installation plate 505 is arranged on the inner side wall of the box cover 2. The installation 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 installation plate 505.

[0036] A rotating groove for rotatably connecting with the rotary outer toothed plate 502 is formed on the inner side wall of the annular plate 501. A cover plate 507 connected to the inner side wall of the box cover 2 is arranged on the outer side wall of the annular plate 501, and the driving device, the transmission gear 504 and the installation plate 505 are all located inside the cover plate 507.

[0037] When the rotary 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 rotary outer toothed plate 502 to rotate, so that the plurality of extrusion blocks 503 on the rotary outer toothed plate 502 sequentially and cyclically extrude the axial movement structure 6, enabling the axial movement structure 6 to cyclically move up and down, thereby continuously driving the circumferential feeding structure 7 to move up and down.

[0038] In this embodiment, the driving device can be a motor or other devices capable of driving the rotating shaft to rotate. The driving device is a prior art and will not be elaborated here.

[0039] The cover plate 507 can prevent raw materials from splashing onto the transmission gear 504, and the rotating groove is used to prevent raw materials from falling onto the tooth surface of the rotary outer toothed plate 502, ensuring the normal operation of the rotary extrusion structure 5.

[0040] The axial movement structure 6 includes a connecting plate 601 connected to the bottom of the box cover 2. A straight pipe 602 coaxial with the corresponding feed pipe 4 is connected to the bottom of the connecting plate 601. A movable pipe 603 is slidably and sealingly sleeved on the top of the straight pipe 602, and the top of the movable pipe 603 is closed. A cross pipe 604 is communicated with the bottom of the movable pipe 603, and the cross pipe 604 is arranged along the radial direction of the annular plate 501. A sliding column 605 is slidably and sealingly sleeved in the cross pipe 604. A hemispherical plate 606 is arranged at one end of the sliding column 605 away from the cross pipe 604, and the spherical surface of the hemispherical plate 606 abuts against the inner side wall of the rotary outer toothed plate 502. A compression spring 607 is sleeved on the sliding column 605, and both ends of the compression spring 607 respectively abut against the end of the cross pipe 604 and one side of the hemispherical plate 606.

[0041] A baffle 608 is provided at the bottom of the connecting plate 601, and the baffle 608 is located directly above the horizontal pipe 604; the straight pipe 602 is fixedly installed on the baffle 608 and penetrates through the baffle 608; two guiding inclined surfaces 609 are symmetrically arranged at the top of the baffle 608, and the tops of the two guiding inclined surfaces 609 intersect.

[0042] When the axial movement 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 on the hemispherical plate 606 guides the squeezing block 503, so that the squeezing block 503 gradually squeezes the hemispherical plate 606, thereby causing the hemispherical plate 606 to drive the sliding column 605 to move into the horizontal pipe 604. At the same time, the compression spring 607 is further compressed. Since the sliding column 605 seals one end of the horizontal pipe 604, the other end of the horizontal pipe 604 is communicated with one end of the straight pipe 602, and the other end of the straight pipe 602 is sealed by the movable pipe 603. Therefore, during the process of the sliding column 605 moving into the interior of the horizontal pipe 604, the sliding column 605 will squeeze the internal gas of the horizontal pipe 604, thereby driving the movable pipe 603 to move upward, and the movable pipe 603 drives the circumferential feeding structure 7 to move upward.

[0043] After the hemispherical plate 606 is separated from the contact with the squeezing block 503, the hemispherical plate 606 is reset to abut against the inner side wall of the annular external tooth plate 502 under the elastic force of the compression spring 607. At this time, the sliding column 605 is also reset synchronously. At the same time, by sucking the gas in the straight pipe 602 and the horizontal pipe 604, a negative pressure can be formed, and due to the self-weight of the circumferential feeding structure 7, the formed negative pressure and the self-weight of the circumferential feeding structure 7 can jointly drive the movable pipe 603 to move downward, and the movable pipe 603 drives the circumferential feeding structure 7 to move downward, so that the circumferential feeding structure 7 presses down on the raw material.

[0044] The baffle 608 can prevent the raw material from dripping onto the horizontal pipe 604, the sliding column 605, the compression spring 607 and the hemispherical plate 606, and ensure the normal movement of the axial movement structure 6. The two guiding inclined surfaces 609 can guide the raw material to flow to both sides of the horizontal pipe 604, accelerate the falling of the raw material, and prevent the raw material from condensing on the baffle 608.

[0045] As an embodiment of the present invention, the circumferential feeding structure 7 includes a connecting shaft 701 rotatably connected to the top of the movable pipe 603. 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 with a fan blade 703 through a first torsion spring, and a limiting plate 704 is arranged on each fan blade seat 702. 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.

[0046] When the movable pipe 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, preventing the feed pipe 4 from being blocked.

[0047] When the connecting shaft 701 moves downward, due to the limitation of the limiting plate 704, the fan blade 703 can rotate upward under the elastic force of the first torsion spring and the extrusion force of the raw material until it abuts against the limiting plate 704. After that, the fan blade 703 stops rotating, so that the fan blade 703 can press down the raw material to flow.

[0048] In this embodiment, the lowest position where the lowermost fan blade 703 can move is below the feed pipe 4, so as to ensure that the raw material is pressed into the mixing box 1.

[0049] The guiding structure 8 includes a guiding rod 801 fixedly connected to the connecting shaft 701. An annular baffle 802 fixedly connected to the guiding rod 801 is in sliding and sealing contact with the inner wall of the feed pipe 4. A guiding groove 803 is formed in the inner wall of the feed pipe 4, and the end of the guiding rod 801 is slidably connected in the guiding groove 803. When the straight pipe 602 moves upward, the guiding rod 801 moves obliquely upward along the guiding groove 803; when the straight pipe 602 moves downward, the guiding rod 801 moves downward along the guiding groove 803.

[0050] The guiding groove 803 includes a plurality of vertical grooves 804 and a plurality of inclined grooves 805. The plurality of vertical grooves 804 and the plurality of inclined grooves 805 are arranged alternately, 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. When the one-way rotating plate 806 is not in contact with the guiding rod 801, the one-way rotating plate 806 abuts against the inner top wall of the inclined groove 805.

[0051] When the connecting shaft 701 moves upward, the guiding rod 801 moves upward synchronously. At the same time, the end of the guiding rod 801 moves obliquely 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 guiding rod 801 moves downward synchronously. At the same time, the end of the guiding rod 801 moves downward along the vertical groove 804 and restricts the connecting shaft 701 from rotating, so that the fan blade 703 presses down the raw material.

[0052] 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 presses against the one-way rotating plate 806 and causes the one-way rotating plate 806 to rotate until the guide rod 801 moves downward and disengages 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 under 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 into contact with 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 into the inclined groove 805, thereby causing the connecting shaft 701 to rotate. The annular baffle 802 is slidably fitted to the inner wall of the feed pipe 4 and can restrict the raw material from entering the inside of the guide groove 803.

[0053] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.

When the one-way rotating plate (806) is not in contact with the guiding rod (801), the one-way rotating plate (806) abuts against the inner top wall of the inclined groove (805).
