Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment, and in particular relates to a PIR tube raw material stirring equipment. Background Art

[0002] Traditional mixing equipment has problems of dead corners and uneven mixing during the mixing process. Due to the gaps between the paddle and the barrel wall, and between the paddle and the barrel bottom, dead corners are caused, and the materials cannot be fully mixed, affecting product quality. At the same time, due to the speed gradient when the mixing blades perform circular motion, the mixing speed near the center of the cylinder is low, while the speed near the barrel wall is higher, resulting in obvious differences in the uniformity of materials in different circumferential zones in the mixing barrel.

[0003] At the same time, when materials accumulate in the corners, they will form a blocking wall, causing the materials to accumulate more and more, and the mixing equipment will be time-consuming and labor-intensive to clean, affecting production efficiency.

[0004] Therefore, it is urgent to develop a new PIR tube raw material mixing equipment to solve the technical problems of how to overcome the dead corners and uneven mixing of traditional mixing equipment.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

On the other hand, even if the inner rotating cylinder 3 and the outer fixed cylinder 2 are worn, it can solve the problem of material leakage, thereby improving the service life of the equipment.

[0042] In at least one embodiment, see Figures 1 to 2 The feeding assembly 4 includes: a fixed frame 41, a feeding funnel 42 and a feeding plate 43; the fixed frame 41 is longitudinally fixed on the mounting platform 1, the feeding funnel 42 is fixedly installed on the fixed frame 41, the feeding plate 43 is connected to the fixed frame 41 and the feeding funnel 42, and the feeding funnel 42 is located above the feeding plate 43.

[0052] Specifically, the stirring drive members 51 are arranged and distributed in the circumferential direction and the axial direction on the inner rotating cylinder 3, so that the stirring blades 52 can stir the PIR tube raw material both horizontally and vertically in the stirring tank 21. At the same time, when the inner rotating cylinder 3 rotates relative to the outer fixed cylinder 2, the stirring blades 52 are also driven to rotate, thereby enhancing the horizontal stirring effect of the stirring blades 52 in the stirring tank 21, achieving all-round and non-dead-angle stirring of the PIR tube raw material in the stirring tank 21, and meeting the requirement of uniform stirring of the PIR tube raw material.

[0053] In at least one embodiment, see Figure 4 The collecting component 6 includes: a collecting container; the collecting container is located below the material drop port.

[0054] Specifically, the collecting container is used to collect the PIR tube raw material after stirring in the stirring tank 21 .

[0056] Specifically, the collecting container is arranged in a ring shape, which can facilitate the installation of the rotating device.

[0057] In at least one embodiment, the collection port of the collection container covers the connection between the outer fixed cylinder 2 and the inner rotating cylinder 3 .

[0058] Specifically, the outer fixed cylinder 2 and the inner rotating cylinder 3 may wear out after long-term relative rotation, but the range of the collection port of the collection container covers the connection between the outer fixed cylinder 2 and the inner rotating cylinder 3. Even if wear occurs, the leakage problem can be solved and the service life of the equipment can be improved.

[0059] In at least one embodiment, a discharge port 61 is provided at the bottom of the collecting container to facilitate discharge.

At the same time, the collecting assembly is located below the outer fixed cylinder and the inner rotating cylinder. On the one hand, it can play the role of receiving raw materials. On the other hand, even if the inner rotating cylinder and the outer fixed cylinder are worn, it can solve the problem of material leakage, thereby improving the service life of the equipment.
