Description

Technical Field

[0001] This utility model relates to the technical field of gypsum board processing equipment, and in particular to a mixer for a gypsum board production line. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. It is one of the new lightweight building materials that is currently being developed. Gypsum board is widely used in interior partitions, wall cladding (replacing wall plaster), ceilings, sound-absorbing panels, floor baseboards, and various decorative panels in various buildings such as residences, office buildings, shops, hotels, and industrial plants. However, it is not suitable for installation in bathrooms or kitchens when used indoors.

[0003] The production process of gypsum board mainly includes several stages such as batching, molding, drying, edge cutting, and stacking. Between the batching and molding steps, a raw material mixing and stirring process is required to fully mix the prepared raw materials so that they are in a liquid or fluid state. Then, the mixed raw materials are shaped by a shaping equipment to obtain the preliminary gypsum board.

[0004] However, in the existing technology, some materials adhere to the inner wall of the mixing equipment during the processing of gypsum board, which leads to contamination of the mixing equipment and waste of raw materials. At the same time, the unidirectional rotation mixing results in uneven mixing of raw materials and slow mixing efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is that during the processing of gypsum board, some material adheres to the inner wall of the mixing equipment, causing contamination of the equipment and waste of raw materials. At the same time, the unidirectional rotational mixing results in uneven mixing of raw materials and slow mixing efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A mixer for a gypsum board production line includes a mixing drum with a discharge port at the bottom. A mixing and stirring shaft is rotatably inserted through the middle of the mixing drum. A transmission gear is fixed to the outer side of the bottom end of the mixing and stirring shaft. A mixing motor is located below the mixing drum and is fixed to the ground. A mixing gear is fixed to the outer side of the output shaft of the mixing motor. The mixing gear meshes with the transmission gear. Multiple centrifugal guide plates are installed in a circular array on the outer side of the top end of the mixing and stirring shaft. A mixing guide plate is fixed to the top end of the centrifugal guide plates.

[0008] Preferably, the centrifugal guide plate is spiral-shaped and its outer edge slides in contact with the inner wall of the mixing tank, and the bottom of the centrifugal guide plate fits seamlessly with the inner floor of the mixing tank.

[0009] Preferably, the mixing guide plate includes a return material guide section and a curved connecting section, the curved connecting section being located between the return material guide section and the top of the centrifugal guide plate, the curved connecting section being C-shaped with a bending angle of half a circle.

[0010] Preferably, the end of the return material guide near the inner wall of the mixing barrel is arc-shaped and fits the inner wall of the mixing barrel, and the center of the arc at the end of the return material guide coincides with the axis of the mixing barrel.

[0011] Preferably, the return material guide is a flat plate and is parallel to the bottom surface of the mixing tank.

[0012] Preferably, the return material guide is a flat plate with one side inclined upwards, and the inclination angle of the return material guide is less than 15 degrees.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. As the spiral centrifugal guide plate rotates with the mixing shaft, the centrifugal force generated by the rotation of the centrifugal guide plate causes the raw material mixture to move upward from the bottom of the centrifugal guide plate, thus exchanging the positions of the bottom and upper layers of the raw material mixture in the mixing tank. This causes the raw material mixture to tumble up and down between adjacent centrifugal guide plates, ensuring thorough mixing, shortening the mixing time, and improving the mixing efficiency.

[0015] 2. A spiral-shaped centrifugal guide plate with its outer edge attached to the inner wall of the mixing tank is used. At the same time, the bottom of the centrifugal guide plate is attached to the inner floor of the mixing tank. During the rotation of the centrifugal guide plate, the raw materials attached to the inner wall and deposited at the bottom of the mixing tank are separated from the inner wall and bottom of the mixing tank, avoiding waste of raw materials and reducing the difficulty of cleaning the inside of the mixing tank after stirring.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1 and Figure 2 As shown, the bottom of the mixing tank 1 is provided with a discharge port, and a mixing and stirring shaft 4 is inserted through the middle of the mixing tank 1. A transmission gear 6 is fixed on the outer side of the bottom end of the mixing and stirring shaft 4. A mixing motor 2 is provided below the mixing tank 1 and is fixed on the ground. A mixing gear 3 is fixed on the outer side of the output shaft of the mixing motor 2. The mixing gear 3 and the transmission gear 6 mesh with each other. Multiple centrifugal guide plates 7 are installed in a circular array on the outer side of the top of the mixing and stirring shaft 4. A mixing guide plate 5 is fixed on the top of the centrifugal guide plate 7. The mixing motor 2 drives the mixing gear 3 and the transmission gear 6 to rotate at high speed, so that the mixing and stirring shaft 4 drives the centrifugal guide plates 7 and the mixing guide plates 5 to rotate at high speed inside the mixing tank 1, centrifugally stirring the raw material mixture liquid inside the mixing tank 1 and promoting the full mixing of the raw materials.

[0024] As a preferred technical solution in this embodiment, such as Figure 3 As shown, the centrifugal guide plate 7 is spiral-shaped and its outer edge slides in contact with the inner wall of the mixing tank 1. The bottom of the centrifugal guide plate 7 is seamlessly attached to the inner ground of the mixing tank 1. When the spiral centrifugal guide plate 7 rotates with the mixing shaft 4, the centrifugal force generated by the rotation of the centrifugal guide plate 7 causes the raw material mixture liquid to move upward from the bottom of the centrifugal guide plate 7, thereby exchanging the positions of the bottom layer and the top layer of the raw material mixture liquid filled in the mixing tank 1.

[0025] In the first embodiment, such as Figure 4As shown, the mixing guide plate 5 includes a return material guide section 51 and a curved connecting section 52. The curved connecting section 52 is located between the return material guide section 51 and the top of the centrifugal guide plate 7. The curved connecting section 52 is C-shaped with a bending angle of half a circle. The end of the return material guide section 51 near the inner wall of the mixing tank 1 is arc-shaped and fits the inner wall of the mixing tank 1. The center of the arc at the end of the return material guide section 51 coincides with the axis of the mixing tank 1. The return material guide section 51 is a flat plate and is parallel to the bottom surface of the mixing tank 1. The return material guide section 51 is used to shield the raw material mixed liquid flowing upward along the surface of the centrifugal guide plate 7, preventing the raw material mixed liquid from splashing out of the mixing tank 1 from the top, thus avoiding raw material waste and pollution of the equipment workshop.

[0026] In the first embodiment, such as Figure 5 As shown, the mixing guide plate 5 includes a return material guide section 51 and a curved connecting section 52. The curved connecting section 52 is located between the return material guide section 51 and the top of the centrifugal guide plate 7. The curved connecting section 52 is C-shaped with a bending angle of half a circle. The end of the return material guide section 51 near the inner wall of the mixing tank 1 is arc-shaped and fits the inner wall of the mixing tank 1. The center of the arc at the end of the return material guide section 51 coincides with the axis of the mixing tank 1. The return material guide section 51 is a flat plate with one side tilted upward. The tilt angle of the return material guide section 51 is less than 15 degrees. The return material guide section 51 is used to block the raw material mixed liquid flowing upward along the surface of the centrifugal guide plate 7, preventing the raw material mixed liquid from splashing out of the mixing tank 1 from the top, thus avoiding raw material waste and pollution of the equipment workshop.

[0027] Working principle: First, the raw materials to be mixed after proportioning are added into the mixing tank 1. Then, sufficient mixed liquid is added to the mixing tank 1. Subsequently, the power supply of the device is turned on and started. The mixing motor 2 is powered on and drives the mixing gear 3 and the transmission gear 6 to rotate at high speed. At this time, the transmission gear 6 drives the mixing and stirring shaft 4, the centrifugal guide plate 7 and the mixing guide plate 5 to rotate. The centrifugal guide plate 7, which is rotating at high speed, separates the raw materials attached to the inner wall of the mixing tank 1 and the raw materials deposited at the bottom of the mixing tank 1 from the mixing tank 1. At the same time, the centrifugal force generated by the rotation of the centrifugal guide plate 7 causes the raw material mixed liquid to adhere to the centrifugal guide plate 7 and move upward from the bottom of the centrifugal guide plate 7. When the raw material mixed liquid reaches the top of the centrifugal guide plate 7, it is restricted by the return guide part 51. The raw material mixed liquid falls back into the mixing tank 1 from the top of the centrifugal guide plate 7, so that the bottom layer of the raw material mixed liquid in the mixing tank 1 exchanges with the upper layer of liquid. This causes the raw material mixed liquid to roll up and down between the adjacent centrifugal guide plates 7, so that the raw materials are fully mixed, shortening the mixing time and improving the mixing efficiency.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
