Description

Technical Field

[0001] The utility model relates to a quick-install steel slag crushing device, belonging to the technical field of steelmaking slag processing. Background Art

[0002] The steelmaking process of steel mills produces a large amount of steel slag, which has the characteristics of high temperature, high density, high strength, rough surface and good stability. The steel slag is crushed by the crushing device on the roller press, but during the roller crushing process, the roller teeth are easy to break and fall off, which reduces the service life; the roller teeth are expensive and the maintenance cost is high; the roller teeth are difficult to replace, and it takes 8 days to replace a set of roller teeth for a single device, which seriously affects normal production. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a quick-install slag crushing device for the above-mentioned prior art, so as to increase the service life of roller teeth; the roller teeth can be quickly replaced, saving time and labor, and improving production efficiency.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a quick-installation slag crushing device, including a cylindrical mounting seat, the mounting seat is horizontally arranged, one end of the mounting seat is fixed to the outer surface of the roller, the other end of the mounting seat is provided with roller teeth, a horizontally arranged tooth seat is provided at the center of one end of the roller teeth, the tooth seat is inserted in the mounting seat, and the mounting seat and the tooth seat are fixedly connected by a pin shaft.

[0005] The tooth seat and the roller teeth are connected via a circular arc segment transition.

[0006] The outer periphery of the mounting seat is provided with a plurality of circumferentially evenly distributed reinforcing ribs, and the reinforcing ribs are fixedly connected to the mounting seat and the roller.

[0007] A groove is formed at one end of the mounting seat, and the groove matches the outer surface of the roller.

[0008] A stop block is arranged at the end of the pin shaft.

[0009] Compared with the prior art, the utility model has the following advantages: a quick-install slag crushing device, the mounting seat and the tooth seat are positioned and fixed by a pin shaft, which is convenient for quickly replacing the roller teeth, saving time and effort, and improving production efficiency. The roller teeth and the tooth seat are connected by a circular arc segment transition, which prevents the stress concentration in the crushing process from causing the roller teeth to break, saving production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a top view of a quick-install slag crushing device according to an embodiment of the utility model;

[0011] In the figure, 1 is a reinforcing rib, 2 is a mounting seat, 3 is a pin shaft, 4 is a roller tooth, 5 is an arc segment, 6 is a stop block, 7 is a tooth seat, and 8 is a roller. DETAILED DESCRIPTION

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 As shown, a quick-install slag crushing device in this embodiment includes a cylindrical mounting seat 2, which is arranged horizontally. An arc-shaped groove is provided at one end of the mounting seat 2, and the groove matches the outer surface of the roller 8. One end of the mounting seat 2 is fixed to the outer surface of the roller 8 by welding, and the mounting seat and the roller are seamlessly connected. A horizontally arranged roller tooth 4 is provided at the other end of the mounting seat 2, and a horizontally arranged tooth seat 7 is provided at the center of one end of the roller tooth 4. The tooth seat 7 is transitionally connected to the end surface of the roller tooth 4 through an arc segment 5. The tooth seat 7 is inserted into the mounting seat, and the mounting seat 2 and the tooth seat 7 are fixedly connected by a pin shaft 3.

[0014] Six circumferentially evenly distributed reinforcing ribs 1 are arranged on the periphery of the mounting seat 2. The reinforcing ribs are fixedly connected to the mounting seat and the roller, and play a reinforcing role in the connection of the mounting seat.

[0015] The mounting seat and the tooth seat are positioned and fixed by a pin shaft, which is convenient for quick replacement and improves production efficiency. A stop block 6 is set at the end of the pin shaft to prevent the pin shaft from falling out. When replacing, just remove the stop block plate, then the pin shaft can be taken out and the roller teeth can be replaced. The roller teeth and the tooth seat are connected by a circular arc segment transition to prevent stress concentration during the crushing process from causing the roller teeth to break, saving production costs. In addition, the roller teeth off the line can be welded and repaired and reused to achieve the purpose of reducing costs.

[0016] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
