Gypsum mixing and pulping machine

Abstract

This utility model discloses a gypsum mixing and pulping machine, belonging to the field of gypsum production technology. It includes: a pulping tank; and a lifting assembly, which is disposed on the inner wall of the bottom surface of the pulping tank. In this utility model, by providing a lifting assembly and a mixing assembly, a rotating column drives a fixed plate to rotate, and the rotating plate drives a rotating rod to circle inside the pulping tank. Under the action of a transmission gear and an internal gear ring, the rotating rod, limited by a limiting strip and a limiting groove, drives the rotating cylinder to rotate. The rotating cylinder drives the stirring rod to agitate the gypsum, achieving simultaneous circular stirring and rotational stirring of the pulping machine, thus increasing the stirring range of the pulping machine. When the connecting plate rotates, it drives a pulley to rotate on a cylindrical cam. At this time, the connecting plate drives the rotating cylinder to move up and down on the outer surface of the rotating column, thereby driving the stirring rod to move up and down as well. This achieves simultaneous rotational stirring and vertical stirring of the pulping machine, ensuring the stirring effect of the pulping machine and further improving the stirring efficiency of the pulping machine.

Description

Technical Field

[0001] This utility model belongs to the field of gypsum production technology, and in particular relates to a gypsum mixing and pulping machine. Background Technology

[0002] Gypsum is a widely distributed mineral with the chemical composition of calcium sulfate dihydrate. Its naturally formed crystals are white in a pure state, but due to impurities, they may also appear yellow, red, brown, or other colors. Calcium sulfate is the main component of gypsum, but it also exists in anhydrous or hemihydrated forms.

[0003] Gypsum is mostly used for interior partitions, interior wall cladding, ceilings, and sound-absorbing panels. Before use, gypsum needs to be made into a slurry, which requires mixing the gypsum with the liquid. This necessitates the use of a slurry mixer. However, most current slurry mixers rotate while fixed in the center of the mixing tank, which limits the mixing range and reduces the mixing efficiency. Therefore, a gypsum mixing and slurry mixing machine has been developed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of limited mixing range and low mixing efficiency of current pulping machines, and to propose a gypsum mixing pulping machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gypsum mixing and pulping machine, comprising: a pulping tank, a feeding hopper connected to the side wall of the pulping tank, a discharge pipe connected to the outer surface of the pulping tank, and a protective cylinder fixedly installed on the inner wall of the bottom surface of the pulping tank;

[0006] A support plate, the lower surface of which is fixedly connected to the upper surface of the pulping tank;

[0007] A lifting assembly is disposed on the inner wall of the bottom surface of the pulping tank;

[0008] A hybrid assembly disposed on the upper surface of a support plate;

[0009] The lifting assembly includes a support column and a connecting plate; the lower surface of the support column is fixedly connected to the inner wall of the bottom of the pulping tank, and a cylindrical cam is fixedly installed on the outer surface of the support column. The outer surface of the cylindrical cam 62 is provided with a sliding groove, which is an annular groove with different heights.

[0010] As a further description of the above technical solution:

[0011] A positioning plate is fixedly installed on the lower surface of the connecting plate. A pulley is rotatably installed on the side wall of the positioning plate via a rotating shaft. The outer surface of the pulley is in contact with the inner wall of the groove of the cylindrical cam. The support column, the cylindrical cam, and the pulley are all located inside the protective cylinder. The cylindrical cam can drive the rotating cylinder to move up and down, thereby driving the stirring rod to move up and down. This allows the rotating cylinder to drive the stirring rod to rotate while moving up and down. The protective cylinder is used to protect the support column and other structures to prevent the gypsum from obstructing the stroke between the cylindrical cam and the pulley during the stirring process.

[0012] As a further description of the above technical solution:

[0013] The other end of the support column passes through the interior of the connecting plate. The upper surface of the connecting plate is provided with a groove, and a rotating cylinder is rotatably installed on the inner wall of the groove.

[0014] As a further description of the above technical solution:

[0015] One end of the rotating cylinder is located inside the pulping tank. A stirring rod is fixedly installed on the outer surface of the rotating cylinder, and a limit strip is fixedly installed on the inner surface of the rotating cylinder.

[0016] As a further description of the above technical solution:

[0017] The hybrid assembly includes a dust cover, the lower surface of which is fixedly connected to the upper surface of the support plate. A servo motor is fixedly installed on the inner wall of the dust cover, and a rotating column is fixedly installed at the output end of the servo motor. The dust cover can block the dust generated by the plaster and protect the servo motor from dust.

[0018] As a further description of the above technical solution:

[0019] One end of the rotating column passes through the interior of the support plate and extends to the lower surface of the connecting plate. One end of the rotating column is rotatably connected to the other end of the support column. A fixing plate is fixedly installed on the outer surface of the rotating column. A rotating rod is rotatably installed on the inner wall of the fixing plate. The rotating column drives the rotating rod to rotate around the pulping tank through the fixing plate.

[0020] As a further description of the above technical solution:

[0021] A transmission gear is fixedly installed on the outer surface of the rotating column, and an internal gear ring is fixedly installed on the inner surface of the pulping tank. The internal gear ring meshes with the transmission gear.

[0022] As a further description of the above technical solution:

[0023] The outer surface of the rotating rod is provided with a limiting groove, one end of the rotating rod extends into the interior of the rotating cylinder, and the outer surface of the limiting strip is slidably connected to the inner wall of the limiting groove. The limiting groove and the limiting strip cooperate to limit the rotating cylinder, ensuring that the rotating cylinder rotates around the pulping tank while rotating on its own axis.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] In this invention, a lifting assembly and a mixing assembly are provided. The rotating column drives the fixed plate to rotate, and the rotating plate drives the rotating rod to circle inside the pulping tank. Under the action of the transmission gear and the internal gear ring, the rotating rod drives the rotating cylinder to rotate under the limitation of the limiting strip and the limiting groove. The rotating cylinder drives the stirring rod to stir the gypsum, realizing that the pulping machine can stir in a circle while rotating, thus improving the stirring range of the pulping machine. When the connecting plate rotates, it drives the pulley to rotate on the cylindrical cam. At this time, the connecting plate drives the rotating cylinder to move up and down on the outer surface of the rotating column, thereby driving the stirring rod to move up and down as well. This realizes that the pulping machine can stir in a circle while stirring in a circle, ensuring the stirring effect of the pulping machine and further improving the stirring efficiency of the pulping machine.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] In specific implementation, such as Figures 1-6 As shown, this utility model provides a technical solution: a gypsum mixing and pulping machine, including a pulping tank 1, a feeding hopper 2 connected to the side wall of the pulping tank 1, a discharge pipe connected to the outer surface of the pulping tank 1, and a protective cylinder 7 fixedly installed on the inner wall of the bottom surface of the pulping tank 1; a support plate 3, the lower surface of which is fixedly connected to the upper surface of the pulping tank 1; a lifting assembly 6, which is disposed on the inner wall of the bottom surface of the pulping tank 1; and a mixing assembly 5, which is disposed on the upper surface of the support plate 3; wherein, the lifting assembly 6 includes a support column 61 and a connecting plate 63; the lower surface of the support column 61 is fixedly connected to the inner wall of the bottom surface of the pulping tank 1, and a cylindrical cam 62 is fixedly installed on the outer surface of the support column 61. The outer surface of the cylindrical cam 62 is provided with a sliding groove, which is an annular groove of different heights. A positioning plate 64 is fixedly installed on the lower surface of the connecting plate 63. A pulley 65 is rotatably installed on the side wall of the positioning plate 64 via a rotating shaft. The outer surface of the pulley 65 is in contact with the inner wall of the sliding groove of the cylindrical cam 62. The support column 61, the cylindrical cam 62 and the pulley 65 are all located inside the protective cylinder 7. The other end of the support column 61 passes through the interior of the connecting plate 63. The upper surface of the connecting plate 63 is provided with a slot. A rotating cylinder 66 is rotatably installed on the inner wall of the slot. One end of the rotating cylinder 66 is located inside the pulping tank 1. A stirring rod 67 is fixedly installed on the outer surface of the rotating cylinder 66. A limit strip 68 is fixedly installed on the inner surface of the rotating cylinder 66.

[0036] When the connecting plate 63 is driven to rotate by the rotating cylinder 66, the connecting plate 63 will drive the positioning plate 64 to rotate synchronously. The positioning plate 64 drives the pulley 65 to rotate in the groove of the cylindrical cam 62. Since the groove of the cylindrical cam 62 is an annular groove of different heights, the pulley 65 moves up and down in the groove when the cylindrical cam 62 rotates. The positioning plate 64 drives the connecting plate 63 to move up and down, thereby causing the connecting plate 63 to move up and down on the outer surface of the rotating column 52. In turn, the rotating cylinder 66 moves up and down, thereby driving the stirring rod 67 to move up and down synchronously, thus realizing up and down stirring. The connecting plate 63 does not contact the rotating column 52. When the rotating rod 54 drives the rotating cylinder 66 to rotate, it drives the connecting plate 63 to rotate.

[0037] like Figure 2 As shown, the mixing component 5 includes a dust cover 51, the lower surface of which is fixedly connected to the upper surface of the support plate 3. A servo motor is fixedly installed on the inner wall of the dust cover 51, and a rotating column 52 is fixedly installed at the output end of the servo motor. One end of the rotating column 52 passes through the interior of the support plate 3 and extends to the lower surface of the connecting plate 63. One end of the rotating column 52 is rotatably connected to the other end of the support column 61. A fixing plate 53 is fixedly installed on the outer surface of the rotating column 52. A rotating rod 54 is rotatably installed on the inner wall of the fixing plate 53. A transmission gear 55 is fixedly installed on the outer surface of the rotating column 52. An internal gear ring 4 is fixedly installed on the inner surface of the pulping tank 1. The internal gear ring 4 meshes with the transmission gear 55. A limit groove 56 is provided on the outer surface of the rotating rod 54. One end of the rotating rod 54 extends into the interior of the rotating cylinder 66. The outer surface of the limit strip 68 is slidably connected to the inner wall of the limit groove 56.

[0038] Gypsum and water are injected into the pulping tank 1 through the feed hopper 2. Then, the servo motor in the dust cover 51 drives the rotating column 52 to rotate. As the rotating column 52 rotates, it drives the fixed plate 53 to rotate synchronously, thereby driving the rotating rod 54 to circle inside the pulping tank 1. The rotating rod 54 drives the transmission gear 55 to circle synchronously. Under the action of the internal gear ring 4, the transmission gear 55 drives the rotating rod 54 to rotate. Under the limit of the limit bar 68 and the limit groove 56, the rotating cylinder 66 rotates synchronously, thereby driving the stirring rod 67 to rotate, thus mixing the gypsum and water in the pulping tank 1. During the mixing process, the liquid level of the gypsum should be lower than the upper surface of the protective cylinder 7.

[0039] Working principle: Gypsum and water are injected into the pulping tank 1 through the feed hopper 2. Then, the servo motor inside the dust cover 51 drives the rotating column 52 to rotate. As the rotating column 52 rotates, it drives the fixed plate 53 to rotate synchronously, thereby driving the rotating rod 54 to circle inside the pulping tank 1. The rotating rod 54 drives the transmission gear 55 to circle synchronously. Under the action of the internal gear ring 4, the transmission gear 55 drives the rotating rod 54 to rotate. Under the limitation of the limiting strip 68 and the limiting groove 56, the rotating cylinder 66 rotates synchronously, thereby driving the stirring rod 67 to rotate, thus stirring the gypsum and water in the pulping tank 1. When mixing occurs, the connecting plate 63 is rotated by the rotating cylinder 66, which in turn drives the positioning plate 64 to rotate synchronously. The positioning plate 64 drives the pulley 65 to rotate in the groove of the cylindrical cam 62. Since the groove of the cylindrical cam 62 is an annular groove of different heights, the pulley 65 moves up and down in the groove when the cylindrical cam 62 rotates. This causes the positioning plate 64 to drive the connecting plate 63 to move up and down, thereby causing the connecting plate 63 to move up and down on the outer surface of the rotating column 52. This, in turn, drives the rotating cylinder 66 to move up and down, which in turn drives the stirring rod 67 to move up and down synchronously, thus achieving up and down stirring.

[0040] 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.
