Description

Technical Field

[0001] This utility model relates to the field of external admixture devices, and in particular to an external admixture device for solid waste cement mill tailings powder. Background Technology

[0002] Solid waste cement mill tailings powder is the product of grinding solid waste remaining after mineral processing. It has resource utilization value, can replace part of cement raw materials or be used as an admixture, and helps to reduce production costs and reduce environmental pollution.

[0003] An existing solid waste cement grinding tailings powder external blending device (publication number CN222270770U) includes a box body, a bottom block, a rotating drum, a first spiral lifting drum, and a second spiral lifting drum. The box body is located on the upper part of the bottom block. The first spiral lifting drum, arranged in a linear array, is located at the lower end of the box body. The rotating drum is located in the middle of the box body, and the second spiral lifting drum is rotatably mounted in the middle of the rotating drum. This device can reduce agglomeration and prevent clogging by continuously stirring the materials, thus solving the problem of existing cement external blending devices lacking a large-scale stirring and conveying effect, which leads to clogging and moisture agglomeration when too much material is added, hindering smooth addition and affecting work progress.

[0004] Although the aforementioned patents can break up materials, the clumping of materials is usually caused by their own moisture. The broken-up materials are very easy to clump up again during transportation. Based on this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a solid waste cement mill tailings powder external mixing device that can overcome or at least partially solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for externally blending tailings powder from a solid waste cement mill includes a shell and further includes: a screening frame slidably connected inside the shell; a feeding pipe connected to the shell; multiple heating plates on the feeding pipe to heat the material; a storage cylinder for short-term storage of tailings powder at the bottom of the shell; a stirring rod rotatably connected inside the storage cylinder; and support legs on the shell; when the screening frame reciprocates horizontally inside the shell, one end of the screening frame moves up and down repeatedly to disperse the agglomerated tailings powder.

[0008] Preferably, the housing is provided with a limiting groove and a sliding groove, the bottom end of the screening frame is provided with a sliding plate, the inner wall of the housing is provided with a sliding groove, and the sliding plate is slidably connected in the sliding groove by rotation.

[0009] Furthermore, a servo motor is provided inside the housing, and the output end of the servo motor is connected to a first rotating disk and a driving synchronous pulley. A second rotating disk and a driven synchronous pulley are rotatably connected inside the housing, and a synchronous belt is connected between the driving synchronous pulley and the driven synchronous pulley.

[0010] Furthermore, an eccentric block is connected to the first rotating disk, a sliding rod is slidably connected in the limiting groove, the sliding rod is slidably connected to the eccentric block, a support groove is provided on the sliding plate, and the other end of the sliding plate is slidably connected in the support groove.

[0011] Furthermore, the second rotating disk is provided with an eccentric shaft, which is rotatably connected to the sliding plate.

[0012] Preferably, the screening frame has screening holes and crushing blocks inside.

[0013] Preferably, the housing is provided with a support plate, a feeding motor is installed on the support plate, the output end of the feeding motor is connected to a spiral auger, and a feeding hopper is provided on the feeding pipe.

[0014] Preferably, a transition cavity is connected between the shell and the storage cylinder, a stirring motor is installed at the bottom of the storage cylinder, and a discharge pipe is connected to the bottom of the storage cylinder.

[0015] Compared with the prior art, this utility model provides a device for externally blending solid waste cement mill tailings powder, which has the following beneficial effects:

[0016] 1. This solid waste cement mill tailings powder external mixing device heats the material by setting multiple heating plates in the feeding pipe. The reciprocating motion of the screening frame drives the material to slide, increasing the relative flow between the material and the air. Combined with the high temperature carried by the material itself, the moisture inside the material is quickly lost.

[0017] 2. In this solid waste cement mill tailings powder external mixing device, during the reciprocating motion of the screening frame, one end of the screening frame performs a small range of up-and-down reciprocating motion, which allows the screening frame to throw the internal material up, further and quickly volatilize the moisture inside the material, and more easily break up the clumps of material.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model can separate wet and dry materials and evaporate the moisture inside the wet material, thus preventing the material from clumping again after being broken up due to the large amount of moisture inside the material itself.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1: Refer to Figures 1-6A device for externally blending tailings powder from a solid waste cement mill includes a shell 1, and further includes: a screening frame 2 slidably connected inside the shell 1, a feeding pipe 13 connected to the shell 1, and multiple heating plates 132 on the feeding pipe 13 to heat the material; a storage cylinder 3 for short-term storage of tailings powder is provided below the shell 1, a stirring rod 32 is rotatably connected inside the storage cylinder 3, and a support leg 11 is provided on the shell 1; when the screening frame 2 moves horizontally reciprocating inside the shell 1, one end of the screening frame 2 moves up and down reciprocally to disperse the clumped tailings powder.

[0029] In this invention, to prevent materials from clumping due to moisture during storage, multiple heating plates 132 are installed in the feeding pipe 13 to heat the material during conveying, thereby increasing the temperature of the material itself. When the heated material falls into the screening frame 2, the screening frame 2 drives the material to slide through reciprocating motion, thereby increasing the relative flow between the material and the air. Combined with the high temperature carried by the material itself, the moisture inside the material can be quickly lost. When the moisture is lost to a certain extent, the material loosens and falls into the storage cylinder 3 below.

[0030] During the reciprocating motion of the screening frame 2, one end of the screening frame 2 moves up and down within a small range, which allows the screening frame 2 to throw the material inside into the air. This action further increases the contact area between the material and the air, as well as the relative flow between the air and the material, so that the clumps of material can quickly evaporate the internal moisture. At the same time, when the material falls back into the screening frame 2, it contacts the bottom plate of the screening frame 2, and the impact of the material further breaks up the clumps of material.

[0031] Example 2: Refer to Figures 1-6The embodiment is basically the same as that in Example 1, but with a further improvement: the housing 1 is provided with a limiting groove 15 and a sliding groove 16, the bottom end of the screening frame 2 is provided with a sliding plate 21, the inner wall of the housing 1 is provided with a sliding groove 16, the sliding plate 21 is rotatably and slidably connected in the sliding groove 16, the housing 1 is provided with a servo motor 4, the output end of the servo motor 4 is connected to a first rotating disk 42 and a driving synchronous wheel 41, the housing 1 is rotatably connected with a second rotating disk 44 and a driven synchronous wheel 43, a synchronous belt 45 is connected between the driving synchronous wheel 41 and the driven synchronous wheel 43, an eccentric block 46 is connected on the first rotating disk 42, a sliding rod 47 is slidably connected in the limiting groove 15, and the sliding rod 47 is connected to the eccentric block. 46. ​​A sliding connection is provided. A support groove 211 is provided on the sliding plate 21. The other end of the sliding plate 21 is slidably connected in the support groove 211. An eccentric shaft 441 is provided on the second rotating disk 44. The eccentric shaft 441 is rotatably connected to the sliding plate 21. A screening hole 22 is opened in the screening frame 2. A crushed block 23 is provided in the screening frame 2. A support plate 12 is provided on the shell 1. A feeding motor 14 is installed on the support plate 12. The output end of the feeding motor 14 is connected to a spiral auger 141. A hopper 131 is provided on the feeding pipe 13. A transition cavity 33 is connected between the shell 1 and the storage cylinder 3. A stirring motor 31 is installed at the bottom end of the storage cylinder 3. A discharge pipe 34 is connected to the bottom end of the storage cylinder 3.

[0032] In this utility model, the screening frame 2 is installed and fixed on the sliding plate 21. When one end of the sliding plate 21 is slidably connected to the sliding groove 16 through the rotating shaft, it can ensure that the sliding plate 21 can slide on the sliding groove 16 while rotating around the rotating shaft. The sliding rod 47 is slidably connected in the limiting groove 15 and slidably connected in the supporting groove 211 through the rotating shaft, so that the sliding rod 47 can drive the other end of the screening frame 2 to reciprocate by sliding up and down, thereby achieving the effect of scattering materials.

[0033] Screening frame 2 has screening holes 22 at its bottom, allowing non-lumpy materials to fall into the storage cylinder 3 below. Multiple crushing blocks are fixed at the bottom of screening frame 2. When the material moves in screening frame 2, large lumps will collide with the crushing blocks 23, thus breaking the large lumps into smaller pieces and accelerating the crushing and screening of the material.

[0034] The servo motor 4 drives the active synchronous wheel 41 to rotate, which in turn drives the driven synchronous wheel 43 to rotate. Thus, one motor can drive the first rotating disk 42 and the second rotating disk 44 to rotate simultaneously. An eccentric block 46 is fixedly connected to the first rotating disk 42. When the first rotating disk 42 rotates, it drives the eccentric block 46 to move up and down. The eccentric block 46 drives the sliding plate 21 to move up and down. One end of the sliding plate 21 slides in the sliding groove 16 through the rotating shaft, so that the sliding plate 21 can rotate up and down slightly around the rotating shaft. At the same time, when the second rotating disk 44 rotates, it drives the sliding plate 21 to move back and forth in the horizontal direction through the eccentric shaft 441.

[0035] By installing a rotatable stirring rod 32 inside the storage cylinder 3, the material inside the storage cylinder 3 can be stirred, thus preventing the material from clumping during accumulation.

[0036] By setting the spiral auger 141 to convey the material to the screening frame 2, the material can be continuously transported, avoiding the reduction of the load on the screening frame 2 by pouring in too much material at one time.

[0037] The discharge pipe 34 is equipped with a solenoid valve, which can open the discharge pipe 34 when needed to allow the material to flow out from the discharge pipe 34;

[0038] Preferably, vents can be provided on the housing 1 to allow air exchange between the inside of the housing 1 and the outside air, thus preventing excessive humidity inside the housing 1.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
