Efficient air cooling structure of breaking hammer

Abstract

The utility model provides an efficient air cooling structure of a breaking hammer, and belongs to the technical field of breaking hammers. The problems that when an existing breaking hammer is used for removing iron slag on a steel-making furnace, the temperature is too high, so that a piston rod is bent and pulled, and a sealing piece is melted and fails are solved. According to the efficient air cooling structure of the breaking hammer, the breaking hammer comprises a shell and a striking cavity, an air inlet and an air outlet are formed in the shell and located on the two sides of the striking cavity respectively, an air inlet channel communicated with the air inlet and an air outlet channel communicated with the air outlet are formed in the two sides of the striking cavity respectively, and a throttling valve is arranged at an outlet of the air inlet channel. The breaking hammer has the advantages of being efficient in heat dissipation and prolonging the service life of the breaking hammer.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of breaking hammer relates to a breaking hammer especially relates to a breaking hammer high -efficient air cooling structure. BACKGROUND

[0002] The iron slag produced after the work of the steel furnace is attached to the furnace wall, and the breaking hammer is used to remove the slag, but due to the high ambient temperature of the steel furnace, the heat generated will enter the middle cylinder through the front cylinder, and the internal parts of the middle cylinder are high-precision structures, so that the piston rod will be bent and strained after high heat enters, and the high temperature will also cause the sealing element to melt and fail, greatly reducing the overall service life of the breaking hammer.

[0010] The following is a specific embodiment of the utility model and is further described with the technical scheme of the utility model in conjunction with the drawings, but the utility model is not limited to these embodiments.

[0011] As Figure 1As shown, the high-efficiency air-cooling structure of the breaking hammer comprises a shell 1 and a striking cavity 2, an air inlet 3 and an air outlet 4 are respectively arranged on the shell 1 and at both sides of the striking cavity 2, the air inlet 3 and the air outlet 4 are arranged at any position communicated with the outside, and an air inlet channel 5 communicated with the air inlet 3 and an air outlet channel 6 communicated with the air outlet 4 are respectively arranged at both sides of the striking cavity 2, a throttle valve 7 is arranged at the outlet of the air inlet channel 5, compressed air is cooled to form low-temperature gas after passing through the throttle valve 7, and the piston is cooled.

[0012] Preferably, the air inlet 3 is in plurality and communicated with the air inlet channel 5.

[0013] Preferably, the air outlet 4 is in plurality and communicated with the air outlet channel 6.

[0014] An air-cooling circulation system is formed by the air inlet and the air outlet to take out the internal heat.

[0015] The specific embodiments described herein merely exemplify the spirit of the present application. Those skilled in the art to which the present application pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0016] Although the terms such as shell 1, striking cavity 2, air inlet 3, air outlet 4, air inlet channel 5, air outlet channel 6 and throttle valve 7 are used more frequently herein, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present application; any kind of additional limitation by interpreting them is contrary to the spirit of the present application.
