An adjustable tamping hammer and its usage method

Abstract

This invention belongs to the field of coking and relates to an adjustable tamping hammer and its usage method. It includes a tamping rod, an upper tamping hammer connected to the bottom of the tamping rod, and a lower tamping hammer positioned below the upper tamping hammer. The lower tamping hammer has a tamping rod lower hammer connection port installed on its surface facing the upper tamping hammer. The lower tamping hammer is connected to the bottom of the tamping rod passing through the upper tamping hammer via this connection port, thus connecting and fixing the upper and lower tamping hammers. The upper and lower tamping hammers have a hollow structure with outwardly extending tamping expansion plates in four directions. This adjustable tamping hammer and its usage method allow the tamping expansion plates to be operated after the tamping hammer enters the sample container, causing the hammer plate in the middle of the hammer to open outward, increasing the hammer area and thus solving the problem of deformation at the sample container inlet, preventing tamping.

Description

Technical Field

[0001] This invention belongs to the field of coking and relates to an adjustable tamping hammer and its usage method. Background Technology

[0002] Small coke ovens can be classified into side-loading, top-loading, and bottom-loading types based on their coal loading method. Different loading methods require different charging equipment. Currently, the main type of small coke oven used in major steel mills, coking plants, and research institutions in China is the 40kg small coke oven. Among these, 40kg top-loading and bottom-loading small coke ovens generally use iron drums for coal loading, while 40kg side-loading small coke ovens generally use cardboard boxes. For iron drum coal loading, the upper part of the drum is prone to deformation due to factors such as the drum material, heating temperature, and quenching method. Generally, after coal is loaded into the upper part of the iron drum, it needs to be tamped using tamping equipment to achieve different bulk densities of the coal cake. The more contact area between the hammer surface of the tamping equipment and the upper surface of the coal cake, the better the tamping effect; conversely, the less contact area, the worse the tamping effect. Normally, the tamping hammer head should match the inlet area of ​​the sample-filling iron drum. However, during the experiment, various factors can cause deformation at the outlet of the iron drum, preventing the tamping hammer head from entering the drum for effective tamping, which is detrimental to the control of the coal cake density in the iron drum. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an adjustable tamping hammer and its method of use, to solve the problem that the inlet of the sample container is deformed and cannot be tamped.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable tamping hammer head, comprising a tamping rod, an upper tamping hammer head connected to the bottom of the tamping rod, and a lower tamping hammer head disposed below the upper tamping hammer head. The lower tamping hammer head has a tamping rod lower hammer head connection port installed on its surface facing the upper tamping hammer head. The lower tamping hammer head is connected to the bottom of the tamping rod passing through the upper tamping hammer head through the tamping rod lower hammer head connection port, thereby connecting and fixing the upper tamping hammer head and the lower tamping hammer head. The upper tamping hammer head and the lower tamping hammer head are hollow, and tamping telescopic plates that can extend outward are respectively provided in four directions.

[0005] Optionally, there are four tamping hammer support columns at the four corners of the upper tamping hammer head, which are installed in conjunction with the lower tamping hammer head.

[0006] Optionally, a power unit is connected to the upper part of the tamping rod to provide tamping power to the tamping hammer head.

[0007] Optionally, a tamping expansion joint is fixedly installed on the tamping expansion joint, and a tamping expansion joint baffle is installed on the tamping expansion joint baffle to prevent the tamping expansion joint from falling off. The tamping hammer head has 4 tamping joint slots, and the tamping expansion joint baffle is correspondingly installed in the tamping joint slots. The expansion and contraction of the tamping expansion joint is controlled by moving it in the tamping joint slots.

[0008] Optionally, the tamping expansion joint baffle is set on the upper surface of the tamping hammer in its natural state, and in this state, the bottom of the tamping expansion joint does not contact the upper surface of the tamping hammer.

[0009] Optionally, the tamping expansion joint stop bar and the tamping expansion joint can be detachably connected.

[0010] Optionally, the tamping disc slot is provided with a serrated or comb-like shape, and the tamping expansion joint is set in the serrated or comb-like shape according to the usage requirements.

[0011] Optionally, the length of the tamping expansion joint is less than the distance between the corresponding four tamping hammer head support columns.

[0012] A method for using an adjustable tamping hammer, applicable to the adjustable tamping hammer as described above, includes the following steps:

[0013] S1, the tamping expansion joint stop bar is inserted downward from the tamping joint slot on the upper surface of the tamping hammer head, the tamping expansion joint moves to the lower surface of the tamping hammer head, the tamping expansion joint stop bar connects with the tamping expansion joint, after the connection is completed, the tamping expansion joint baffle contacts the tamping joint slot, the tamping joint slot prevents the tamping expansion joint from falling off.

[0014] S2, the tamping hammer head and the tamping rod are connected through the tamping rod hammer head connection port;

[0015] S3. After the coal sample is filled into the sample iron bucket, the tamping hammer head slowly enters the sample iron box and is positioned on the upper surface of the coal. Move the tamping telescopic plate stop rod so that the tamping telescopic plate extends out of the upper surface of the tamping hammer head. When the tamping telescopic plate contacts the wall of the iron bucket, stop moving the tamping telescopic plate stop rod and engage it with the tamping plate slot.

[0016] S4, the tamping hammer head tamps the coal with the power given by the tamping rod. During the tamping process, the tamping telescopic plate comes into contact with the lower surface of the tamping upper hammer head, thereby preventing the tamping telescopic plate from moving upward. The tamping telescopic plate and the tamping lower hammer head work together to tamp the coal in the iron bucket.

[0017] S5. After tamping is completed, move the tamping hammer head upward and move the tamping telescopic plate stop bar so that the tamping telescopic plate enters the tamping hammer head.

[0018] S6, the tamping hammer head moves upward and leaves the sample container, thus completing the tamping operation.

[0019] The beneficial effects of the present invention are as follows: The present invention provides an adjustable tamping hammer and its method of use. After the tamping hammer enters the sample container, the tamping telescopic plate is operated, that is, the hammer plate in the middle of the hammer opens outward, increasing the hammer area, thereby solving the problem that the inlet of the sample container is deformed and tamping cannot be performed.
