Description

Technical Field

[0001] The utility model relates to the technical field of zinc liquid component detection, in particular to a precise sampling device for a zinc pot of a galvanizing line. Background Art

[0002] During the production process of galvanized home appliance sheets, it is necessary to timely control the composition of the zinc pot of the galvanizing line. This composition plays a vital role in the quality of galvanized home appliance sheets. Therefore, reliable monitoring of the zinc pot composition is a decisive factor in the quality control of home appliance galvanized sheets, which determines the surface quality of the steel coils after galvanizing.

[0003] Specifically, during the production of the galvanizing line, the composition of the zinc pot will always be brought into the zinc pot with the iron powder of the cold-rolled sheet and the aluminum and iron elements in the zinc pot will be taken out of the zinc pot with the output of the galvanized sheet. Therefore, the overall composition of the zinc pot has been in a dynamic balance. If the quality of the home appliance plate needs to be guaranteed at a good level, the content of elements such as Al needs to be controlled to be within a very narrow range to ensure the stability of the surface quality of the home appliance plate. However, since the sampling process of our daily practical sampling bucket in the zinc pot will be affected by factors such as the zinc slag on the surface, the sampled samples have been fluctuating after multiple measurements, which has a great impact on our on-site technicians' control of the zinc slag in the zinc pot, making it difficult to ensure the stability of the zinc pot composition and timely adjustment to ensure the best surface quality of galvanized home appliance plates. In extreme cases, there have been cases where the composition is controlled in the opposite direction of the target. Therefore, how to efficiently and accurately measure the composition of the zinc pot has become one of the key factors for quality personnel to control the surface quality of galvanized plates.

[0004] For example, Chinese patent CN215677677U discloses a galvanized zinc pot sampling device, which includes a sampling rod, a cover slide rod, a cover and a sampling spoon, and a sliding ring and a slide rod that keep the cover and the sampling spoon in cooperation.

[0005] However, when sampling in the zinc pot, it is difficult to judge the depth of the sampling spoon into the zinc liquid in the zinc pot, and it is difficult to sample the zinc liquid at a specified position; at the same time, the tilt of the sampling rod during sampling will affect the judgment of the sampling depth, and when taking out the zinc liquid, it is easy to cause the zinc liquid to spill.

[0006] Based on this, the utility model designs a precise sampling device for the zinc pot of a galvanizing line to solve the above problems. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the prior art, the utility model provides a precise sampling device for the zinc pot of a galvanizing line.

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] The side of the sampling cylinder is fixedly connected to the lower end of the sampling rod, the lower side of the sampling rod is hinged to the lower side of the connecting rod, and the lower end of the connecting rod is fixedly installed with a rotating cover for closing the upper end opening of the sampling cylinder;

[0011] A positioning node is fixedly installed on the upper side of the sampling rod for observing the depth of the sampling tube entering the zinc pot; a stabilizing component is also installed on the upper end of the sampling rod for keeping the sampling tube vertical.

[0012] Furthermore, a reinforcing rod for increasing the connection strength is provided on the lower side of the sampling rod, one end of the reinforcing rod is fixedly connected to the sampling rod, and the other end of the reinforcing rod is fixedly connected to the sampling tube.

[0014] Furthermore, the sampling rod and the reinforcing rod are made of SUS316 stainless steel.

[0015] Furthermore, the sampling tube, rotating cover and positioning node are made of SUS321 stainless steel.

[0016] Furthermore, a circular hole is opened on the side of the sampling rod, and a circular ring is fixedly installed on the side of the connecting rod; the circular hole on the side of the sampling rod is rotatably connected to the circular ring on the side of the connecting rod.

[0017] The invention has the following advantages over the prior art: 1. the sampling rod and the connecting rod are kept parallel, and the rotary cover is sealed at the opening of the sampling tube, and the sampling tube and the rotary cover are extended into the zinc pot through the sampling rod and the connecting rod, and the depth of the sampling tube and the rotary cover is observed by the positioning node. After reaching a certain depth, the connecting rod is operated to drive the rotary cover to rotate, so that the rotary cover no longer blocks the opening of the sampling tube, and the zinc liquid in the zinc pot flows into the sampling tube for sampling. After the sampling is completed, the connecting rod is operated to drive the rotary cover to rotate, so that the rotary cover blocks the opening of the sampling tube; thereby, the upper zinc liquid is prevented from entering the sampling tube, and the zinc liquid at the specified position in the sampling tube is collected, thereby ensuring the accuracy of the sampling composition; ensuring that the sampled sample is not contaminated, and ensuring the quality of the sampling; the invention realizes precise depth position sampling, and at the same time has a simple structure, low actual use cost, and is easy to operate. It is suitable for sampling of household appliance plate production in a galvanizing line, and greatly reduces the probability of abnormal component analysis caused by abnormal sampling in the zinc pot;

[0018] 2. At the same time, the sampling rod and sampling tube are kept moving vertically through the stabilizing assembly to avoid spillage of zinc liquid. At the same time, the sampling depth can be accurately determined through the cooperation of the positioning nodes. BRIEF DESCRIPTION OF THE DRAWINGS
