Description

Technical Field

[0001] The utility model relates to the technical field of casting material production, in particular to a feeding device for non-stick aluminum casting material. Background Art

[0002] In the aluminum industry, non-stick aluminum castable is an important refractory material, widely used in aluminum smelting, aluminum casting and other processes. Non-stick aluminum castable is generally made of alumina, calcium oxide, magnesium silicate, Roman powder, bauxite and other raw materials, and has excellent high temperature resistance and corrosion resistance after casting. In the production process of non-stick aluminum castable, a series of processing steps are required, including material bagging.

[0003] The traditional unloading process of non-stick aluminum castables usually includes the following steps: first, the castables are transported from the storage bin to the unloading device after batching by manual or mechanical means; then, the castables are packaged by the bagging machine at the bottom. However, due to the strong adhesion of the particles themselves and possible humidity changes, non-stick aluminum castables are very prone to agglomeration. Small pieces of castables will fall into the packaging bag in blocks, affecting the bagging effect. Large agglomerates will cause blockages during the unloading process and even cause equipment failures. Whenever a blockage occurs, the production line needs to be stopped for cleaning, causing production interruptions, affecting the overall production rhythm and product delivery time. Therefore, in response to the above problems, we proposed a unloading device for non-stick aluminum castables. Utility Model Content

[0004] The utility model aims to provide a feeding device for non-stick aluminum casting material, so as to solve the problems that the existing feeding device may cause the casting material to agglomerate, resulting in poor bagging effect, equipment blockage and the like.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0028] The utility model provides a feeding device for non-stick aluminum casting material, please refer to Figures 1 to 3, including a blanking cylinder 1; a screening assembly 2, the screening assembly 2 includes a screening plate 201 and a material dialing impeller 202 arranged below the screening plate 201; a driving motor 3; a transmission mechanism 4, the transmission mechanism 4 is arranged between the screening assembly 2 and the driving motor 3.

[0029] The blanking cylinder 1 includes a feeding hopper 101 arranged at its top, a discharge port 102 arranged at the bottom of the blanking cylinder 1, and a pair of fixed seats 103 arranged inside the blanking cylinder 1; the screening plate 201 is elastically connected to the bottom of the fixed seat 103 through a plurality of springs 201a; the material dialing impeller 202 is supported by a transmission shaft 202a and a bearing inside the blanking cylinder 1.

[0030] The transmission mechanism 4 includes a driving rod 401, a connecting rod 402 arranged at one end of the driving rod 401, and a transmission belt 403 arranged on one side of the driving rod 401; the driving rod 401 is fixed and driven by the driving motor 3; the driving rod 401 includes a cam 401a and a dialing rod 401b; the length of the dialing rod 401b is greater than that of the cam 401a, and is used to dial the screening plate 201 to vibrate up and down; one end of the connecting rod 402 is a single rod, connected to the cam 401a, and the other end is a double rod, connected to the two side surfaces of the screening plate 201, and the driving rod 401 drives the connecting rod 402 to drive the screening plate 201 to vibrate left and right; one end of the transmission belt 403 is connected to the driving rod 401, and the other end is connected to the transmission shaft 202a, and the driving rod 401 can drive the material dialing impeller 202 to rotate.

[0031] It should be noted that the feeding hopper 101 is an inverted conical frustum with an open top, which is used to convey the casting material from the storage bin to the blanking device manually or mechanically after batching. The discharge port 102 has a smaller diameter for aligning with the packaging bag. An opening and closing valve is arranged in the discharge port 102 to control the opening and closing of the discharge port 102 during bagging. The aperture diameter and quantity of the screening holes of the screening plate 201 can be adjusted according to actual needs. The four corners above the screening plate 201 are fixed on the fixed seats 103 through springs 201a. There are a pair of fixed seats 103, which are respectively fixedly installed on the inner wall of the blanking cylinder 1. Using elastic connection with springs 201a can absorb vibration and reduce the impact force during the blanking process, thereby protecting the screening plate and other equipment components. At the same time, the elasticity of the springs can keep the screening plate flexible during vibration, promote the smooth passage of particles, and improve the screening efficiency.

[0032] Preferably, the drive motor 3 is fixedly installed outside the wall of the blanking cylinder 1. The drive motor 3 transmits the drive to the transmission mechanism 4 through the drive rod 401. There is a limit slot in the drive rod 401 inserted into the drive motor 3. A cam 401a is fixed at the end of the drive rod 401. The side of the cam 401a facing away from the drive rod 401 is hinged to the single rod end of the connecting rod 402. The other double rod end of the connecting rod 402 is hinged to both sides of the screening plate 201, as Figure 2 shown; there are two dial rods 401b, which are arranged in a decentralized manner with respect to the cam 401a, as Figure 3 shown, and the length of the dial rod 401b is greater than that of the cam 401a.

[0033] Preferably, pulley wheels are installed outside the drive rod 401 and outside the transmission shaft 202a. The transmission belt 403 is installed on the surfaces of the two pulley wheels. The material dialing impeller 202 is fixedly installed on the transmission shaft 202a, and it is located above the discharge port 102 and directly below the screening plate 201. The material dialing impeller 202 is composed of a plurality of arc-shaped fan blades installed on its surface. When the material dialing impeller 202 rotates, it can effectively dredge the discharge port 102, prevent the pouring material from accumulating and blocking during the discharging process, and ensure the smooth progress of the blanking process.

[0034] During use, when the drive motor 3 drives the drive rod 401 to rotate, the following three motions will occur:

[0035] 1. The cam 401a drives the screening plate 201 through the connecting rod 402. The screening plate 201 will perform horizontal reciprocating motion from left to right. At the same time, due to the fixing method of the spring 201a, the screening plate 201 will also generate some vibrations;

[0036] 2. When the drive rod 401 rotates, the dial rod 401b will touch the bottom of the screening plate 201. When the drive rod 401 rotates at a high speed, the two dial rods 401b will continuously contact the bottom of the screening plate 201, causing the screening plate 201 to vibrate up and down. Here, the rotation direction of the drive rod 401 should be counterclockwise, so that the dial rod 401b moves from the bottom of the screening plate 201 to the edge, which can provide a better vibration effect;

[0037] 3. When the drive rod 401 rotates, it will simultaneously drive the material dialing impeller 202 to rotate through the pulley wheels and the transmission belt 403. By designing the size ratio of the pulley wheels, the rotation speed of the material dialing impeller 202 can be adjusted to control the material dialing effect and effectively dredge the discharge port 102.

[0038] In summary, the feeding device of the non-stick aluminum castable of the present utility model effectively separates small pieces of castable through the screening function of the screening component, reduces the influence of castable caking on the feeding effect. The design of the dial rod and the connecting rod driving the vibrating screen plate to vibrate elastically enables the castable to fall through the screen holes more evenly and quickly, improving the overall feeding speed and ensuring a smoother feeding process. And through the linkage design of the feeding impeller and the screening plate, the discharge port can be dredged in time to prevent equipment blockage caused by large pieces of castable, ensuring the continuity of the production process. In addition, through effective screening and feeding control, the appearance of lumpy castable in the packaging bag is reduced, improving the consistency and quality of the final product.

[0039] The above description is only a description of the preferred embodiments of the present utility model, and does not limit the scope of the present utility model in any way. Any changes and modifications made by those of ordinary skill in the art of the present utility model according to the above disclosure shall fall within the protection scope of the claims.
