Utility Model Content

[0003] The utility model aims to provide a grinding and feeding device for processing wear-resistant castables, which is used to solve the problem that when the grinding device of the existing small workshop performs grinding work, the material supply efficiency easily affects the grinding effect of the castables, causing the castables to be ground intermittently at irregular intervals, resulting in differences in the finished ground products and affecting the grinding effect.

[0011] The utility model has the following beneficial effects: The structure of the utility model is reasonably designed and simple. The lifting material is quantitatively separated by the rotatable discharge disk with a material distribution bin. After a certain amount of casting material accumulates, it is conveyed to the subsequent grinding device, ensuring that the material entering the grinding device is constant each time. When the feeding frequency is uncertain, the material entering the grinding device is kept constant, forming a stable grinding frequency and ensuring the stable discharge of the ground product; by setting counterweights and the spaced-apart material distribution bins, a non-powered tipping device is formed.

Detailed implementation mode

[0015] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0016] As Figures 1 to 2 In an embodiment of the grinding and feeding device for wear-resistant castable processing of the present utility model shown in the figure, it includes a hoist 1 for lifting the castable. The hoist 1 is provided with a feed inlet 11 and a discharge outlet 12, and includes a quantitative aggregate device 2 for quantitatively receiving the material flowing out of the discharge outlet 12; the quantitative aggregate device 2 includes a material inlet 21 for the material to enter, an aggregate bin 22 for temporarily aggregating the material, a guide bin 23 for guiding the material into the subsequent grinding device, and a discharge plate 3 for isolating the aggregate bin 22 from the guide bin 23; the discharge plate 3 includes a hinge shaft 31 hinged on the side wall of the aggregate bin 22 and a distribution bin 33 that rotates around the hinge shaft 31 to communicate with or isolate from the aggregate bin 22. The lifting material is quantitatively separated by the rotatable discharge plate with a distribution bin. After a certain amount of castable is aggregated, the castable is conveyed to the subsequent grinding device, ensuring that the material entering the grinding device is constant each time. Under the condition of an uncertain feeding frequency, the material entering the grinding device is ensured to be constant, forming a stable grinding frequency and ensuring the stable discharge of the ground product.

[0017] Specifically, a sector-shaped counterweight 32 is fixed on the hinge shaft 31 and is arranged at an interval from the distribution bin 33; in the natural state, the distribution bin 33 communicates with the aggregate bin 22, and the distribution bin 33 and the guide bin 23 are both in an isolated state. By setting the counterweight and the spaced distribution bin, a non-powered tipping device is formed. When the distribution bin is full, it just drives the discharge plate to flip, so that the distribution bin faces the guide bin for rapid pouring of the castable. After the pouring is completed, the discharge plate is quickly reset under the action of the counterweight, and the material in the distribution bin is loaded again.

[0018] Specifically, the distribution bin 33 includes two distribution plates 331 that are perpendicular to each other and the ends of which are fixed on the hinge shaft 31; the top surface of the distribution plate 331 in the natural state is lower than the top surface of the other distribution plate 331. The distribution bin is composed of two distribution plates that are perpendicular to each other and asymmetric about the vertical plane of the hinge axis in the natural state, which is convenient for realizing the center of gravity offset of the full distribution bin 33 and realizing the rapid flipping of the discharge plate.

[0019] Specifically, the included angle between the distribution plate 331 and the horizontal plane is 35° to 40°.

[0020] Specifically, two arc-shaped plates 34 are provided on the discharge plate 3 to connect the ends of the two distribution bins 33 far from the hinge shaft 31 and the ends of the sector-shaped counterweight 32.

[0021] Specifically, the elevator 1 includes a vertical lifting cylinder 13, a spiral lifting blade 14 disposed within the vertical lifting cylinder 13, and a drive motor 15 for driving the rotation of the spiral lifting blade 14; a feed inlet 11 is provided at the lower part of the side wall of the vertical lifting cylinder 13; a discharge outlet 12 is provided at the upper part of the side wall of the vertical lifting cylinder 13.

[0022] Working principle: The staff pours the material into the feed inlet 11. Under the action of the elevator 1, the material is lifted to the discharge outlet 12, enters the aggregate bin 22 from the material gathering port 21, and is retained in the distribution bin 33 communicating with the aggregate bin 22. The casting material gradually accumulates. When the distribution bin 33 is about full, the self-weight of the casting material in the distribution bin 33 can just drive the discharge tray 3 to rotate downward around the hinge shaft 31 until the distribution bin 33 communicates with the material guiding bin 23. The inertia drives the discharge tray 3 to continue swinging until the distribution bin 33 approaches the vertical plane where the hinge shaft 31 is located. The casting material quickly separates from the distribution bin 33, enters the subsequent grinding device through the material guiding bin 23 for grinding. When the distribution bin 33 faces downward, the arc-shaped plate 34 isolates and seals the aggregate bin 22. The lifted casting material is temporarily stored in the aggregate bin 22. The casting material in the distribution bin 33 quickly separates in its inclined downward state and, under the action of the sector-shaped counterweight 32, the distribution bin 33 deflects upward again. After the distribution bin 33 communicates with the aggregate bin 22 again, the casting material is refilled in the distribution bin 33. During the filling process, the subsequent grinding device continues to grind. After filling to full load, the above operations are continued. The distribution bin 33 separates the casting material quantitatively for grinding, ensuring that the casting material entering the subsequent grinding device remains stable, ensuring a stable feeding frequency to the grinding device, forming a stable grinding process, and ensuring stable grinding products.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
