Description

Technical Field

[0001] The invention relates to the technical field of production and processing of building materials, and in particular to a device for mixing slag micropowder and steel slag micropowder. Background Art

[0002] The composite powder produced by mixing slag powder and steel slag powder is particularly suitable for large-volume concrete components. It can increase the liquid alkalinity of concrete, reduce the corrosion of steel bars, and thus extend the service life of civil engineering structures.

[0003] In the prior art, when slag powder and steel slag powder are mixed, the two materials are usually poured directly into a mixing barrel (a barrel-shaped outer shell, a mixing shaft is rotatably installed inside the barrel-shaped outer shell, and a mixing rod is arranged on the outside of the mixing shaft) at one time, and the two materials are evenly mixed with the help of the mixing rod in the mixing barrel. This has the following disadvantages: firstly, the mixing time of the materials is long and the mixing efficiency is low; secondly, the mixing uniformity of the materials cannot be effectively guaranteed. In order to solve the problem of sufficient mixing of the materials, most scholars have proposed improvement plans that are generally aimed at the mixing rod in the mixing barrel (essentially a stirring structure). If improvements can be made from the perspective of the feeding method, for example, the two materials can be fed alternately and pre-mixed during the feeding process, which can also improve the mixing rate of the materials. In view of this, the present invention is proposed. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a device for mixing slag micropowder and steel slag micropowder, which solves the current problem of low mixing efficiency by changing the feeding method of the two materials.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

The upper and lower parts of the preliminary mixing box are both opened, and the lower part of the preliminary mixing box is connected to the interior of the mixing barrel.

[0009] Among them, two feeding ports are arranged below the feed hopper, and feeding trough bodies are slidably installed below the two feeding ports respectively.

[0010] Furthermore, a swing plate is slidably installed under the feed hopper, and a driving assembly is provided under the swing plate to drive the swing plate to swing left and right. Two feeding troughs of the swing plate are respectively fixedly installed on the swing plate. The feeding trough body includes a trough body, and sealing plates are provided on both sides of the trough body. The sealing plates are used to block the discharge port when the feeding trough body is misaligned with the discharge port under the feed hopper.

[0011] Furthermore, the driving assembly includes a driving motor, a first transmission shaft is arranged above the driving motor, a turntable is rotatably installed below the swing plate to drive the swing plate to slide left and right, and the first transmission shaft drives the turntable to rotate through a bevel gear set.

[0013] Furthermore, the knocking assembly includes a rotating shaft, a linkage gear is fixedly mounted on the rotating shaft, a gear row for driving the linkage gear to rotate is provided on the side of the swing plate facing the knocking assembly, both ends of the rotating shaft are provided with torsion springs for driving the rotating shaft to reset, the two ends of the torsion spring are respectively connected to the support platform and the rotating shaft, and a knocking plate is fixedly mounted on the rotating shaft.

[0014] Furthermore, a vibration plate is detachably installed inside the groove body, a linkage plate is arranged on the side of the vibration plate, one end of the linkage plate extends from the groove body toward one end of the knocking assembly, and the linkage plate is aligned with the knocking plate.

[0015] Furthermore, two arc plates are symmetrically arranged inside the preliminary mixing box, and a material discharge space is left between the two arc plates. A semicircular swing plate is rotatably installed above the arc plate, and a material discharge filter plate is arranged on the semicircular swing plate. The material discharge filter plate is arranged in the middle of the semicircular swing plate. When the material discharge filter plate coincides with the material discharge space, the material falls into the mixing barrel.

[0016] Furthermore, it also includes a second transmission shaft, which is linked to the first transmission shaft through a gear set, and a reciprocating rotating member is arranged below the second transmission shaft, and the reciprocating rotating member is used to drive the semicircular swing plate to swing.

[0020] The present invention provides a swinging plate, which drives the trough bodies of the two feeding troughs to align with the two discharge ports below the feed hopper respectively. When the swinging plate slides to the left, it drives the two feeding troughs to slide to the left, so that the lower part of the feeding trough body on the left side full of slag powder or steel slag powder is aligned with the upper part of the guide tube on the left side, so that the material inside the feeding trough body on the left side full of slag powder or steel slag powder enters the left guide tube from the feeding trough body, and enters the mixing barrel along the guide tube. Then, the swinging plate slides to the right, so that the feeding trough body on the right side drives another material to fall into the right guide tube and slide into the mixing barrel. The two materials enter the mixing barrel alternately in turn, so that the materials are easier to mix inside the mixing barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] An embodiment of the present invention provides a device for mixing slag micropowder and steel slag micropowder, the purpose of which is at least to provide a feeding trough 21, and the two feeding troughs 21 swing back and forth to alternately convey slag micropowder and steel slag micropowder to the inside of a mixing barrel 1, so that when the material is subsequently conveyed inside the mixing barrel 1, the slag micropowder and steel slag micropowder can be mixed more quickly and evenly.

[0037] Embodiment: A device for mixing slag micropowder and steel slag micropowder, such as Figure 1-Figure 3 As shown, it includes a mixing barrel 1, which is used to mix slag micropowder and steel slag micropowder evenly;

[0038] A feed hopper 2 is installed above the mixing barrel 1 and is used to quantitatively transport slag powder and steel slag powder into the mixing barrel 1. Two guide pipes 3 are respectively arranged on both sides below the feed hopper 2. The upper ends of the two guide pipes 3 are respectively connected to the lower sides of the feed hopper 2.

[0039] The preliminary mixing box 5 is used to receive the materials conveyed by the two material guide pipes 3 and perform preliminary mixing on the materials. The upper and lower parts of the preliminary mixing box 5 are both opened, and the lower part of the preliminary mixing box 5 is connected to the interior of the mixing barrel 1;

[0040] There are two feeding ports below the feed hopper 2 , and feeding troughs 21 are slidably installed below the two feeding ports. The feeding troughs 21 are used to quantitatively transport slag powder and steel slag powder to the inside of the two guide pipes 3 .

[0041] In the present invention, slag powder and steel slag powder are conveyed to the inside of the mixing barrel 1 in sequence from the bottom of the feed hopper 2, so that the slag powder and steel slag powder can fall into the mixing barrel 1 alternately in sequence, so that the slag powder and steel slag powder can be mixed more quickly and evenly during the mixing process. At the same time, two feeding troughs 21 are used to convey the slag powder and steel slag powder respectively. When there is no need to weigh the slag powder and steel slag powder, the mixing ratio of the slag powder and the steel slag powder can also be controlled, so that the mixing process of the slag powder and the steel slag powder can be simpler to operate.

[0042] Among them, the internal volume size of the two feeding troughs 21 is adapted to the matching ratio of slag micropowder and steel slag micropowder, so that each time the two feeding troughs 21 transport materials into the mixing barrel 1, the ratio of slag micropowder and steel slag micropowder inside the mixing barrel 1 conforms to the matching ratio of slag micropowder and steel slag micropowder.

[0043] Furthermore, if Figure 4 As shown, a swing plate 4 is slidably installed below the feed hopper 2, and a driving component for driving the swing plate 4 to swing left and right is provided below the swing plate 4. Two feeding troughs 21 of the swing plate 4 are respectively fixedly installed on the swing plate 4, and the feeding trough 21 includes a trough body 211, and sealing plates 212 are provided on both sides of the trough body 211. The sealing plates 212 are used to block the discharge port when the feeding trough body 21 is misaligned with the discharge port below the feed hopper 2.

[0044] Among them, by setting a swing plate 4, the swing plate 4 drives the trough bodies 211 of the two feeding trough bodies 21 to align with the two discharge ports below the feed hopper 2, and when the swing plate 4 slides to the left, it will drive the two feeding trough bodies 21 to slide to the left, so that the lower part of the feeding trough body 21 on the left side full of slag powder or steel slag powder is aligned with the upper part of the guide pipe 3 on the left, so that the material inside the feeding trough body 21 on the left side full of slag powder or steel slag powder enters from the feeding trough body 21 into the left guide pipe 3, and enters into the mixing barrel 1 along the guide pipe 3, and then the swing plate 4 slides to the right, so that the feeding trough body 21 on the right side drives another material to fall into the right guide pipe 3, and slide into the mixing barrel 1, and the two materials enter the mixing barrel 1 alternately in turn, so that the materials are easier to mix inside the mixing barrel 1.

[0045] It should be noted that a partition is provided in the middle of the feed hopper 2, and the two sides of the feed hopper 2 are respectively used to transport slag powder and steel slag powder, and a support plate 22 is fixedly installed under the feed hopper 2, and the support plate 22 is used to fix the position of the feed hopper 2, and the support plate 22 is set at an opening corresponding to the discharge port position of the feed hopper 2.

[0046] Furthermore, if Figure 2 As shown, the driving assembly includes a driving motor 42, a first transmission shaft 43 is arranged above the driving motor 42, a turntable 41 is rotatably installed below the swing plate 4 to drive the swing plate 4 to slide left and right, and the first transmission shaft 43 drives the turntable 41 to rotate through a bevel gear set.

[0047] Furthermore, if Figure 4 , Figure 6 As shown, a support platform 23 is fixedly installed above the material guide tube 3, and a material discharge hole 2301 is arranged on the support platform 23. The top of the material guide tube 3 is connected with the material discharge hole 2301, and the swing plate 4 is slidably installed on the support platform 23. A knocking component 24 for knocking the side wall of the feeding trough 21 is arranged on the support platform 23.

[0048] Among them, by setting a feed discharge hole 2301 on the support platform 23, the feeding trough 21 can be easily slid horizontally. Only when the opening below the feeding trough 21 is connected with the feed discharge hole 2301, the material can fall downward from the inside of the feeding trough 21 to the inside of the material guide tube 3. When it is not aligned, the bottom of the feeding trough 21 is blocked.

[0049] Furthermore, if Figure 5As shown, the knocking assembly 24 includes a rotating shaft 241, on which a linkage gear 242 is fixedly mounted, and a gear row 45 for driving the linkage gear 242 to rotate is provided on the side of the swing plate 4 facing the knocking assembly 24, and both ends of the rotating shaft 241 are provided with torsion springs 243 for driving the rotating shaft 241 to reset, and the torsion spring 243 is used to drive the rotating shaft 241 to rotate in a direction away from the swing plate 4, and both ends of the torsion spring 243 are respectively connected to the support platform 23 and the rotating shaft 241, and a knocking plate 25 is fixedly mounted on the rotating shaft 241.

[0050] Among them, by setting a knocking assembly 24 on the support platform 23, when the feeding trough 21 moves to the left or right under the drive of the swing plate 4, the tooth row 45 on the swing plate 4 will engage with the linkage gear 242 of the knocking assembly 24, so that the linkage gear 242 drives the rotating shaft 241 to rotate, and the rotating shaft 241 drives the knocking plate 25 to knock the side of the feeding trough 21, ensuring that all the materials inside the feeding trough 21 fall from the discharge through hole 2301 to the inside of the guide tube 3.

[0051] In addition, a baffle 244 is provided on the side of the support platform 23 , and the baffle 244 is used to prevent the rotating shaft 241 from moving in a direction away from the swing plate 4 , so that the knocking plate 25 on the rotating shaft 241 is in a vertical state under normal conditions.

[0052] Furthermore, if Figure 6 , Figure 7 As shown, a vibration plate 214 is detachably installed inside the groove body 211 , and a linkage plate 213 is provided on the side of the vibration plate 214 , one end of the linkage plate 213 extends from the groove body 211 toward one end of the knocking assembly 24 , and the linkage plate 213 is aligned with the knocking plate 25 .

[0053] Among them, by setting a vibration plate 214 inside the trough body 211 and setting a linkage plate 213 on the side of the vibration plate 214, one end of the linkage plate 213 can directly contact the knocking plate 25 when the knocking plate 25 rotates, thereby avoiding the knocking plate 25 from knocking on the trough body 211 for a long time to cause deformation of the side of the trough body 211 and avoid affecting the mixing ratio of slag micropowder and steel slag micropowder.

[0054] Furthermore, if Figure 8 As shown, two arc plates 51 are symmetrically arranged inside the preliminary mixing box 5, and a material discharge space is left between the two arc plates 51. A semicircular swing plate 52 is rotatably installed above the arc plate 51, and a material discharge filter plate 53 is arranged on the semicircular swing plate 52. The material discharge filter plate 53 is arranged in the middle of the semicircular swing plate 52. When the material discharge filter plate 53 coincides with the material discharge space, the material falls into the mixing barrel 1.

[0055] Among them, by arranging a semicircular swing plate 52 inside the preliminary mixing box 5 and arranging a material discharge filter plate 53 on the semicircular swing plate 52, not only can the material be filtered, but also the material can be briefly stayed inside the preliminary mixing box 5, so that the two materials can be preliminarily mixed in the preliminary mixing box 5, which can further improve the mixing efficiency of slag micropowder and steel slag micropowder.

[0056] Furthermore, if Figure 2 , Figure 4 As shown, it also includes a second transmission shaft 44, which is linked to the first transmission shaft 43 through a gear set. A reciprocating rotating member 54 is arranged below the second transmission shaft 44, and the reciprocating rotating member 54 is used to drive the semicircular swing plate 52 to swing.

[0057] Furthermore, if Figure 8 As shown, the reciprocating rotating member 54 includes an inner semicircular gear, an outer semicircular gear is arranged at the center of the inner semicircular gear, a reciprocating gear 541 is arranged between the inner semicircular gear and the outer semicircular gear, a linkage shaft 521 is arranged on the semicircular swing plate 52, and the reciprocating gear 541 is fixedly mounted on the linkage shaft 521 of the semicircular swing plate 52.

[0058] Among them, by setting the inner semicircular gear and the outer semicircular gear, the unidirectional rotation of the second transmission shaft 44 can be converted into the reciprocating rotation of the reciprocating gear 541, which can conveniently drive the semicircular swing plate 52 to swing back and forth inside the preliminary mixing box 5, so that the slag powder and the steel slag powder can be preliminarily mixed inside the preliminary mixing box 5.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
