Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, specifically to a mixing device for processing heat insulation materials. Background Technology

[0002] Thermal insulation materials are materials that impede the transfer of heat; they are also known as heat-insulating materials. Traditional thermal insulation materials include fiberglass, asbestos, rock wool, and silicates, while newer thermal insulation materials include aerogel felt and vacuum panels. The production process of thermal insulation materials involves mixing various raw materials in a fixed proportion using a mixing device.

[0003] Existing mixing devices simply use a stirring rod for unidirectional stirring. The insulation material is located at the bottom and is difficult to turn over, resulting in poor stirring effect and difficulty in meeting the mixing requirements of insulation materials. Furthermore, the discharge of materials from the mixing device is also a major problem. Raw materials adhering to the inner wall and accumulating in the discharge pipe will affect the processing of insulation materials. There is an urgent need to design a mixing device for processing insulation materials to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for processing thermal insulation materials, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mixing device for processing thermal insulation materials includes a mixing tank, a feed inlet at the top of the mixing tank, a rotating cylinder rotatably fitted inside the mixing tank, a plurality of stirring blades arranged around the circumference of the rotating cylinder, a drive mechanism installed at the top of the mixing tank, and a first connecting rod rotatably fitted inside the top of the rotating cylinder. The drive mechanism cooperates with the rotating cylinder and the first connecting rod. The bottom end of the rotating cylinder is rotatably and slidably fitted with a second connecting rod. A connecting mechanism is provided between the first connecting rod and the second connecting rod. The bottom of the mixing tank is provided with a discharge port and a cylinder. The bottom of the second connecting rod is fixedly connected to a movable cover corresponding to the discharge port. The cylinder passes through the output end of the bottom of the mixing tank and is connected to the movable cover. The top of the movable cover is provided with multiple blades. Support rods are provided on both sides of the rotating cylinder, and a scraper is provided at one end of each of the two support rods.

[0006] Furthermore, the bottom of the mixing tank is provided with multiple support legs, the top of the feed inlet is provided with a feed hopper, the top of the feed hopper is provided with a cover plate, and the discharge port is provided with a valve.

[0007] Furthermore, the drive mechanism includes a drive box mounted on the top of the mixing tank, a drive motor mounted on one side of the drive box, a first bevel gear mounted on the output end of the drive motor, a second bevel gear sleeved on one end of the rotating cylinder, and a third bevel gear sleeved on one end of the first connecting rod. The first bevel gear meshes with the second and third bevel gears, and the first, second, and third bevel gears are located inside the drive box.

[0008] Furthermore, the connecting mechanism includes a square rod disposed at the top of the second connecting rod and a square groove formed at the bottom of the first connecting rod, wherein the square rod is slidably fitted within the square groove.

[0009] Furthermore, a conical slide is provided at the bottom of the inner wall of the mixing tank, the movable cover is conical, and a bearing is provided between the movable cover and the cylinder output end.

[0010] Furthermore, the scraper is arc-shaped, the scraper is inclined, and the bottom of the scraper is provided with an extension rod corresponding to the conical slide.

[0011] In the above technical solution, the mixing device for processing heat insulation materials provided by this utility model has the following beneficial effects: The connecting mechanism enables the drive mechanism to rotate the rotating cylinder and the first connecting rod. The first connecting rod, through the connecting mechanism, drives the second connecting rod to rotate, which in turn drives the moving cover to rotate. The moving cover then drives multiple blades to stir, and since the stirring direction is different from that of the stirring blades, it facilitates the turning over of the insulation material at the bottom of the mixing tank, thus improving the stirring effect of the device. The moving cover can also be activated by a cylinder to move the moving cover upward, causing it to move upward and separate from the discharge port, allowing the insulation material to be discharged from the discharge port. The obstruction of the moving cover reduces the accumulation of raw materials at the main discharge port during the processing, while the scraper can clean the raw materials adhering to the inner wall of the mixing tank.

[0022] Reference Figure 3 The drive mechanism 5 in this embodiment includes a drive box 18 installed on the top of the mixing tank 1, a drive motor 19 installed on one side of the drive box 18, a first bevel gear 20 installed at the output end of the drive motor 19, a second bevel gear 21 sleeved on one end of the rotating cylinder 3, and a third bevel gear 22 sleeved on one end of the first connecting rod 6. The first bevel gear 20 meshes with the second bevel gear 21 and the third bevel gear 22. The first bevel gear 20, the second bevel gear 21 and the third bevel gear 22 are located inside the drive box 18. The drive motor 19 drives the first bevel gear 20 to rotate, which in turn drives the second bevel gear 21 and the third bevel gear 22 to rotate. The second bevel gear 21 and the third bevel gear 22 then drive the rotating cylinder 3 and the first connecting rod 6 to rotate, which in turn drives the rotating cylinder 3 to rotate multiple stirring blades 4. The first connecting rod 6 drives the second connecting rod 7 to rotate through the connecting mechanism 8, which in turn drives the moving cover 11 to rotate. The moving cover 11 then drives multiple blades 12 to rotate. The stirring directions of the multiple stirring blades 4 and the multiple blades 12 are opposite. The drive box 18 can protect the gear meshing points.

[0023] Reference Figure 3 In this embodiment, the connecting mechanism 8 includes a square rod 23 disposed at the top of the second connecting rod 7 and a square groove 24 formed at the bottom of the first connecting rod 6. The square rod 23 is slidably fitted within the square groove 24.

The extension rod 27 can push the material in the conical slide 25 into the discharge port 9 for discharge.

[0026] Working principle: In use, the raw materials are first put into the mixing tank 1 through the feed inlet 2. After the raw materials are prepared, the drive mechanism 5 is started, which drives the rotating cylinder 3 and the first connecting rod 6 to rotate. The rotating cylinder 3 and the first connecting rod 6 rotate in opposite directions. The rotation of the rotating cylinder 3 will drive multiple stirring blades 4 to stir the raw materials in the mixing tank 1. At the same time, the first connecting rod 6 will drive the second connecting rod 7 to rotate through the connecting mechanism 8. The second connecting rod 7 will drive the moving cover 11 to rotate. The rotation of the moving cover 11 will drive multiple blades 12 to stir the raw materials. The stirring blades 4 and the blades 12 stir in opposite directions, making it easier for the raw materials to mix. After the stirring is completed, the cylinder 10 is started, which drives the moving cover 11 to move upward. At this time, the raw materials can be discharged from the discharge port 9 at the bottom of the mixing tank 1. At the same time as the material is discharged, the rotation of the rotating cylinder 3 will drive the support rod 13, which will drive the scraper 14 to clean the inner wall of the mixing tank 1.
