Description

Technical Field

[0001] This utility model relates to the field of multiple frequency sieve technology, specifically to a tool for cleaning the sieve holes of a two-stage multiple frequency sieve. Background Technology

[0002] The secondary frequency screen is installed in the coke storage tower and is used to screen mixed coke. Coke produced in the coke oven is transported to the coke storage tower by a conveyor belt. It first enters the primary frequency screen to separate coke particles larger than 25mm. Coke particles ≤25mm pass through the screen holes and enter the secondary frequency screen. The secondary frequency screen has 10mm screen holes to separate small coke particles from coke powder. Coke particles of different sizes are then stored in corresponding bins for ironmaking. However, during the separation of small coke particles and coke powder, the screen holes are easily clogged by coke powder due to the small screen holes (10mm) and the presence of water in the mixed coke. Workers need to enter the screen box to clear the screen holes and restore the frequency screen's function. However, the space inside the secondary frequency screen box is small, the screen plates are installed at a 20° angle, and there are many screen holes to clean—more than 4000 in total—making the cleaning process time-consuming, labor-intensive, and posing safety risks. Utility Model Content

[0003] The purpose of this utility model is to provide a tool for cleaning the screen holes of a two-stage multi-frequency screen, which makes it easier for employees to clean the screen holes of the two-stage multi-frequency screen, and speeds up the cleaning process while ensuring the safety of employees.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tool for cleaning the screen holes of a secondary frequency screen includes a handle rod, a conversion rod, and a cleaning head. The conversion rod is a threaded sleeve with threads on both its inner and outer surfaces. One end of the conversion rod is threadedly connected to the handle rod, and the other end is threadedly connected to the cleaning head. A limiting plate is also fitted on the cleaning head, which divides the cleaning head into a connecting section and a cleaning section, and the length ratio of the connecting section to the cleaning section is 4:1 to 2:1.

[0006] Furthermore, the handle rod is 1~1.5m long, the conversion rod is 20~30cm long, and the cleaning head is 10~15cm long.

[0007] This utility model has the following beneficial effects:

[0008] 1. The special tool for cleaning the screen holes of the two-stage multi-frequency screen provided by this utility model allows employees to stand outside the multi-frequency screen to clean and unclog the screen holes, which saves time and effort and ensures the safety of the cleaning personnel.

[0009] 2. The special tool for cleaning the screen holes of the two-stage multi-frequency screen provided by this utility model allows each component to be disassembled and replaced. When a component is damaged, only the damaged component needs to be replaced, without replacing the entire tool, which is both convenient and cost-effective.

[0010] 3. The special tool for cleaning the screen holes of the secondary frequency screen provided by this utility model has a cleaning head made of 310S stainless steel, which can extend the service life of the cleaning head due to its wear resistance; in addition, the handle is made of carbon steel pipe, which makes the tool easy to use. By using different materials according to the performance of different parts, the service life of the tool can be extended and its processing cost can be reduced. Attached Figure Description

[0012] In the diagram, 1-handle lever, 2-conversion lever, 3-limiting plate, 4-cleaning head. Detailed Implementation

[0013] The present invention will be further explained below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a tool for cleaning the screen holes of a two-stage multi-frequency sieve includes a handle rod 1, a conversion rod 2, and a cleaning head 4. The conversion rod 2 is a threaded sleeve with threads on both its inner and outer surfaces. One end of the conversion rod 2 is threadedly connected to the handle rod 1, and the other end is threadedly connected to the cleaning head 4. A limiting plate 3 is also fitted onto the cleaning head 4, dividing the cleaning head 4 into a connecting part and a cleaning part, with the length ratio of the connecting part to the cleaning part being 4:1 to 2:1. The handle rod 1 is 1 to 1.5 m long, the conversion rod 2 is 20 to 30 cm long, and the cleaning head 4 is 10 to 15 cm long.

[0015] In its specific manufacturing process, the handle rod 1 is 1.5m long, the conversion rod 2 is 25cm long, and the cleaning head 4 is 12cm long. The length ratio of the connecting part to the cleaning part on the cleaning head 4 is 3:1. The connecting part is cylindrical and has threads on its surface for connection with the conversion rod; the cleaning part is prismatic and has a pointed head for easy insertion into the screen holes to clean the coke powder clogging the screen. After assembling the cleaning tool in sequence, workers can hold the handle rod and stand outside the multi-frequency screen box to clean the coke powder inside the screen holes. The operation is time-saving, labor-saving, and ensures the safety of the cleaning personnel.
