Technical Field

[0001] This utility model relates to the field of waste oil filtration technology, specifically a waste oil filtration device for an oil testing mechanism in mining equipment. Background Technology

[0002] Mining equipment refers to various mechanical equipment and tools used in the mining production process. It is mainly used for operations such as mining, transportation, crushing, screening, and flotation. It also includes special equipment and auxiliary mechanical equipment used for underground or open-pit mining. Mining equipment is widely used in the production process of coal, ferrous metals, non-ferrous metals and other mines, and is an indispensable and important part of mining operations.

[0003] Mining equipment requires the use of lubricating oil and hydraulic oil, which need to be cleaned over long-term use. The oil tanks become heavily contaminated, and direct oil changes are wasteful. Therefore, based on the oil testing mechanism of the mining equipment, waste oil is filtered to reduce contamination and allow for continued use. This requires a corresponding filtration device, typically using a filter screen. However, if the filter screen is difficult to install and remove, it can affect the subsequent filtration effect and cause inconvenience to the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a waste oil filtration device for a mining equipment oil testing mechanism, in order to solve the problem mentioned in the background art that the filter screen is generally used for filtration, but if the filter screen is inconvenient to install and disassemble, it will easily affect the subsequent filtration effect and cause inconvenience to the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste oil filtration device for a mining equipment oil testing mechanism, comprising equipment pipes and a filter cylinder. Internal threaded grooves are fixed on both sides of the inner wall of the filter cylinder, and threaded joints are threadedly connected to the internal threaded grooves. A connecting pipe is fixed to the side of the threaded joint. Hollow annular plates are fixed on both sides of the inner wall of the filter cylinder, and positioning pins are fixed to the sides of the annular plates. Filter plates are assembled on the sides of the annular plates, and a third mounting hole is opened in the filter plates. A second locking nut is installed on the side of the positioning pin. A filling area for filling is formed between the left and right filter plates, and a discharge port is connected to the middle position of the bottom of the filter cylinder.

[0006] As a further technical solution of this utility model, the positioning posts are distributed in a ring about the center of the ring plate, and the third mounting holes are distributed in a ring in the filter plate.

[0007] As a further technical solution of this utility model, the third mounting hole corresponds one-to-one with the position of the positioning post, and the positioning post and the second locking nut form a threaded connection.

[0008] As a further technical solution of this utility model, the discharge port is equipped with a valve, and the internal thread groove and the threaded joint form a threaded assembly.

[0009] As a further technical solution of this utility model, the ring plates are symmetrically distributed about the central axis of the filter cylinder, and the connecting pipes are symmetrically distributed on both sides of the filter cylinder.

[0010] As a further technical solution of this utility model, a second mounting hole is provided in the connecting pipe, a connecting pipe is provided between the equipment pipeline and the connecting pipe, and limit plates are fixed on both sides of the connecting pipe.

[0014] By installing and fixing the ring plate on both sides of the inner wall of the filter cartridge, the ring plate is hollow and the positioning post is fixed on the side of the ring plate. When assembling the filter plate, the positioning post can be positioned to pass through the inside of the third mounting hole, and then the position is locked with the second locking nut. This facilitates the installation and assembly of the filter plate. At the same time, there is a filling area between the left and right filter plates, so one filter plate can be assembled first, and then filled with, for example, activated carbon in the filling area, and then the other filter plate can be assembled. This improves the filtration capacity during operation and facilitates the replacement of the filter plates.

[0015] By fixing internal thread grooves on both sides of the inner wall of the filter cylinder, the threaded joint can be threaded at the position of the internal thread groove, thus completing the connection and assembly of the connecting pipe. Therefore, it is convenient to assemble the connecting pipes at both ends during operation and to connect and assemble with the equipment pipeline in the future. In addition, a discharge port is installed at the bottom of the filter cylinder, so the packing in the packing area can be discharged at the discharge port, thereby improving the overall convenience.

A discharge port 8 is connected to the middle position of the bottom of the filter cylinder 4.

[0024] The positioning posts 18 are distributed in a ring around the center of the ring plate 15, and the third mounting holes 17 are distributed in a ring in the filter plate 16.

[0025] The third mounting hole 17 corresponds to the position of the positioning post 18, and the positioning post 18 and the second locking nut 19 form a threaded connection.
