Abstract

The utility model relates to a hammer of a reversible counter-impact pulverizer. The whole hammer has a rectangular integral structure. One end of the hammer handle is the hammer head; the other end is semicircular, and a pin hole is concentric with the semicircle; the front and rear sides of the hammer handle are respectively provided with a stepped back iron near the pin hole. Because the hammer head and the hammer handle are integrated, the accident that the hammer head falls off and damages the belt is avoided. The front and rear sides of the hammer handle are equipped with protective irons, which prevents the rotor from being damaged when the hammer stops running. Compared with the split hammer, it adopts welding or forging molding, which is convenient for processing and production, improves the service life of the hammer, reduces the time and labor intensity of the operator to replace the hammer, and saves costs.

Description

A reversible impact crusher hammer

technical field

The utility model belongs to the field of coking equipment, in particular to a hammer of a reversible impact pulverizer used for pulverizing blended coal.

Background technique

The hammer on the reversible impact pulverizer used in the metallurgical coking plant is an important part of pulverization. Its main function is to pulverize the coal through the rotation and impact of multiple hammers. This hammer is composed of two parts: hammer head and hammer handle. The hammer head is half hollow and half solid, and the hollow part is set on the hammer handle, and the hammer head and the hammer handle are connected together by a short rod. The purpose of the original design of this split hammer is to replace only the hammer head after the hammer head is worn out without changing the hammer handle, which can save energy and reduce consumption. However, in actual production, it is found that because the hollow part of the hammer head is thin, when the pulverizer passes over metal or hard debris such as iron, the wall of the hammer head is easily broken by the debris and falls off. Higher, there are often problems that the hammer head falls off and smashes the belt or damages the rotor of the pulverizer, thereby increasing consumption and cost.

Contents of the invention

The purpose of this utility model is exactly to solve above-mentioned problem, provides a kind of simple in structure, easy to manufacture, use safe and reliable one-piece pulverizer hammer.

The technical solutions of the utility model are:

A reversible impact pulverizer hammer, including a hammer head and a hammer handle, is characterized in that the whole hammer is a rectangular integrated structure, one end of the hammer handle is a hammer head; the other end is a semicircle, concentric with the semicircle pin hole.

The front and rear sides of the hammer handle are respectively provided with a stepped back iron near the pin hole.

The one-piece hammer is welded or forged, and the hammer head is a square solid structure.

The beneficial effects of the utility model are:

Because the hammer head and the hammer handle of the utility model adopt an integral structure, there is no problem that the hammer head falls off, so the accident that the hammer head smashes the belt is avoided. The front and rear sides of the hammer handle are equipped with protective irons, which also prevents the problem of damaging the rotor when the hammer stops running. Since the hammer is welded or forged in one piece, it is easy to process and shape, and greatly improves the service life of the hammer and reduces operator replacement. The time and labor intensity of the hammer is reduced, the safety is increased, and the cost and expenses are saved.

Description of drawings

Figure 1 is a front view of the reversible impact crusher hammer.

Figure 2 is a top view of the hammer of the reversible impact crusher.

Among the figure: 1 is a hammer head, 2 is a hammer handle, 3 is a back iron, and 4 is a pin hole.

Detailed ways

The utility model will be further described in conjunction with the accompanying drawings.

As can be seen from Figure 1, the reversible impact crusher hammer is composed of a hammer head 1, a hammer handle 2, a back iron 3 and a pin hole 4. The whole hammer is a rectangular one-piece structure, that is, the hammer head 1 and the hammer handle 2 are integrated. One end of the hammer handle 2 is a hammer head 1; the head of the other end is semicircular to facilitate the installation of the hammer. There is a pin shaft hole 4 at the same center as the semicircle; the front and rear sides of the hammer handle 2 are close to the front and rear sides of the hammer handle 2 on the inner side of the pin shaft hole 4. A stepped back iron 3 is respectively arranged. The main functions of the back irons 3 on both sides are: When the hammer stops rotating and falls, it can be stuck on the guard plates on both sides of the rotor to prevent the hammer head from smashing the rotor.

The integrated hammer of the reversible impact pulverizer of the utility model is formed by welding (or forging). The hammer head 1, the hammer handle 2 and the back iron 3 are all solid bodies. After processing respectively, the three are welded according to requirements. together. In order to reflect the characteristics and functions of the hammer head 1, the thickness of the square hammer head 1 is thicker than that of the hammer handle 2, so its mass is also large, and the impact force and inertia after rotation are naturally much larger.

Claims (3)

1, a kind of reversible reaction type pulverizer hammer comprises tup and hammer handle, it is characterized in that whole hammer is the rectangle integral structure, and hammer handle one end is a tup; Other end head semicircular in shape is provided with pin shaft hole with this semi-circular concentric.

2, reversible reaction type pulverizer hammer according to claim 1 is characterized in that described tup is square solid construction.

3, reversible reaction type pulverizer hammer according to claim 1 is characterized in that, the two sides respectively is provided with a trapezoidal shape break iron near the pin shaft hole place before and after the hammer handle.
