Description

Technical Field

[0001] The utility model relates to a filter box before a lubrication pump applied to a lubrication system of a single-cylinder cone crushing station, belonging to the technical field of single-cylinder cone crushing stations. Background Art

[0002] The single-cylinder cone crusher is a medium-fine crusher and an indispensable part of the crushing production line. It is widely used in metal mining, sand and gravel aggregate and other industries. The lubrication system of the crushing station supports the normal use and maintenance of the crusher. However, due to the harsh working environment and the large amount of dust inside the main machine, the lubricating oil has a low cleanliness after being used for a certain period of time, which will cause wear and even damage to the lubrication pump and the internal components of the main machine. At this time, the lubricating oil needs to be filtered.

[0003] The filter units in the existing single-cylinder cone crushing station lubrication system are generally return oil screen filtration (coarse filtration) and lubrication pump post-filter filtration to protect the internal components of the main engine.

[0004] However, the existing single-cylinder cone crushing station lubrication system has the following shortcomings:

[0005] The return oil screen filtration in the lubrication system is only a coarse filtration, which can only filter out larger particles of foreign matter (iron filings, dust, etc.) brought out from the inside of the main engine. However, smaller particles of impurities will enter the oil tank and enter the oil pump through the oil pump suction port. In the long run, it will cause wear and tear on the internal structure of the pump, resulting in insufficient flow in the lubrication system, and in severe cases, it will damage the main engine. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a pre-filter box for a lubrication pump, which is installed at the oil suction port on the inner side of the lubrication oil tank. It performs two-pass filtering before the lubrication pump to filter out impurities with smaller particle sizes. A strong magnet is installed inside to absorb iron filings with smaller particles, thereby protecting the lubrication pump and extending the life of the pump. In addition, the filter box has a small spatial size and is convenient for disassembly and cleaning.

[0007] The utility model is implemented according to the following technical solutions:

[0008] In the first aspect, the utility model provides a pre-filter box for a lubrication pump, which is mainly used in a lubrication system of a single-cylinder cone crushing station. The pre-filter box for the lubrication pump is installed at the oil suction port on the inner side of the lubrication oil tank, and comprises:

[0012] In some embodiments, the first filter plate and the second filter plate are first spliced ​​together by snapping, and then the first and second filter plates are fixed together by detachable fasteners.

[0013] In some embodiments, the first filter plate and the second filter plate after splicing are a hollow rectangular structure as a whole, which are spliced ​​together at the top of the rectangular structure in the length direction by a first clamping structure and at the bottom of the rectangular structure in the length direction by a second clamping structure.

[0014] In some embodiments, the first filter screen plate is composed of a bottom plate and three side plates extending vertically upward around the periphery of the bottom plate; the second filter screen is a bent plate used to form the top plate and the fourth side plate of the filter box.

[0015] In some embodiments, the side plate of the second filter is embedded between two opposite side plates of the first filter plate, and the top of the second filter is located on the top surface of the three side plates of the first filter plate; the tops of the two corresponding side plates of the first filter plate are each provided with a corresponding groove, and first protrusions are provided on both sides of the corners of the bent plate of the second filter, and the two first protrusions are respectively inserted into the corresponding grooves, thereby forming a first clamping structure.

[0016] In some embodiments, at least one second protrusion is provided on the bottom surface of the side plate of the second filter screen, and a positioning slot corresponding to the second protrusion is provided on the bottom plate of the first filter screen plate, and the second protrusion is inserted into the positioning slot to form a second snap-fit ​​structure.

[0018] In some embodiments, the strong magnetic component includes:

[0019] Cylindrical magnet;

[0020] A threaded rod, which passes through the first filter plate, and the cylindrical magnet is sleeved in the threaded rod;

[0021] Two nuts are respectively screwed on the two ends of the threaded rod located outside the first filter plate.

[0024] Beneficial effects of the utility model:

[0025] The utility model performs two filtrations in front of the lubricating oil tank. The first filter plate filters out smaller impurities. When the oil enters the filter box, the iron filings that are most harmful to various components of the system are attracted by the strong magnet, and the second filter plate filters impurities with smaller particle sizes, thereby cleaning the oil source at the source, thereby protecting the lubricating pump and extending the life of the pump. Since the filter box can be drawn out and disassembled conveniently, the impurities left in the filter box are easy to clean, thereby extending the life of the lubricating pump and the internal components of the host at a lower cost.

Of course, the first and second filter plates are not limited to the above specifications and can be modified accordingly according to actual needs.

[0037] For further solutions, please refer to Figure 1 , Figure 2 As shown, the first filter plate 1 and the second filter plate 2 are firstly spliced ​​together by means of snap connection, and then the first and second filter plates are fixed together by means of detachable fasteners.

[0038] The preferred solution is to continue to refer to Figure 1 , Figure 2 As shown, the first filter plate 1 and the second filter plate 2 after splicing are a hollow rectangular structure as a whole, which are spliced ​​together at the top of the rectangular structure in the length direction by a first clamping structure and at the bottom of the rectangular structure in the length direction by a second clamping structure.

[0040] Embodiment 1: The side plate of the second filter 2 is embedded between the two opposite side plates of the first filter plate 1, and the top of the second filter 2 is located on the top surface of the three side plates of the first filter plate 1; the tops of the two corresponding side plates of the first filter plate 1 are each provided with a corresponding groove 15, and first protrusions 10 are provided on both sides of the curved plate corners of the second filter 2, and the two first protrusions 10 are respectively inserted into the corresponding grooves 15, thereby forming a first clamping structure.
