Description

Technical Field

[0001] This utility model relates to an end cap mounting structure for a basket filter, belonging to the technical field of basket filters. Background Technology

[0002] Basket filters are used in oil or other liquid pipelines to filter out debris. The filter pore area is 2-3 times larger than the pipe diameter area, far exceeding the filter area of ​​Y-type and T-type filters. The filter precision is among the best of all filters. The filter screen structure is different from other filter screens. It is named basket filter because its shape resembles a basket.

[0003] Chinese Patent (Announcement No.: CN 216878225 U) discloses a basket filter end cap mounting structure, which includes: a through pipe and a flange fixedly connected to the upper end of the through pipe, the flange having through holes arranged in a ring; a top cover having circular holes arranged in a ring matching the through holes, the top cover being fixedly connected to the flange by screws; and a sealing component, the sealing component including a mounting groove, an air bladder, and a gasket, the mounting groove being formed on the flange, the lower side wall of the air bladder being fixedly connected to the mounting groove, and the gasket being fixedly connected to the upper surface of the air bladder. The sealing component is used for sealing between the flange and the top cover. In this invention, the air bladder in the through pipe expands due to the increase of gas, pushing the gasket upward, so that the gasket, under the push of the air bladder, comes into contact with the lower side wall of the top cover, thereby achieving the effect of sealing the connection between the flange and the top cover and avoiding oil leakage.

[0004] The aforementioned patent uses a traditional threaded bolt installation method, but this method is relatively complex and requires ensuring that multiple bolts are tightened to the same degree. Otherwise, it can easily lead to uneven stress on the top cover, affecting its sealing performance, and the installation process is also relatively time-consuming.

[0005] To address this, a basket filter end cap mounting structure is proposed. Utility Model Content

Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model embodiment provides a basket filter end cap mounting structure, including a basket filter body 1, with connecting pipes 2 connected to both the left and right sides of the basket filter body 1, a collar 3 fixedly connected to the outer surface of the basket filter body 1, first connecting ears 4 fixedly connected to both the left and right sides of the collar 3, a top cover 5 provided on the top of the basket filter body 1, second connecting ears 6 fixedly connected to both the left and right sides of the top cover 5, and an installation mechanism 7 provided on the outer side of each of the first connecting ears 4, and the first connecting ears 4 and the second connecting ears 6 are detachably connected through the installation mechanism 7. The installation mechanism 7 includes two slots 701, which are respectively opened on the front and rear sides of the inner surface of the first connecting ears 4. A connecting post 702 is fixedly connected to the outer side of each slot 701, and a pressure spring 703 is wound around the outer surface of each connecting post 702. A moving block 704 is fixedly connected to the other end of the pressure spring 703, and a first insert rod 705 is fixedly connected to the inner side of each moving block 704.

[0031] By setting the installation mechanism 7, the second connecting lug 6 and the top cover 5 can be easily installed, avoiding the use of traditional threaded bolts. This can prevent uneven stress on the top cover 5 during installation, which would affect the sealing performance of the top cover 5. Furthermore, it saves time and effort during installation and is easy to disassemble.

[0032] Example 2

[0033] like Figure 5 As shown, in one embodiment, a sealing device 8 is provided at the bottom of the top cover 5. The sealing device 8 includes a fixing ring 801. An annular airbag 802 is fixedly connected to the outer surface of the fixing ring 801. An air supply pipe 803 is connected to the top of the annular airbag 802. The air supply pipe 803 passes through the top of the top cover 5 and extends to the outside. The other end of the air supply pipe 803 is connected to an air pump 804. The air pump 804 is fixedly connected to the top of the top cover 5.

[0034] By setting the sealing device 8, the sealing performance of the top cover 5 can be further improved, preventing leakage and the outflow of filtered media.

[0035] In operation, the present invention works as follows: First, the filter screen 16 is snapped into the inner side of the slot 18 to complete the installation of the filter screen 16. At this time, the top cover 5 is placed on the top of the basket filter body 1, and the actuating rod 13 is pulled outwards. The actuating rod 13 drives the moving block 704 to move outwards at the same time. As the moving block 704 moves, it will compress the pressure spring 703, causing the pressure spring 703 to deform. At this time, the second insert rod 9 is inserted into the inner side of the first slot 10. Then, the actuating rod 13 is released. At this time, since the pressure spring 703 is not under force, it will... The movable block 704 moves inward, driving the first insertion rod 705 to move inward until the first insertion rod 705 is inserted into the inner side of the second slot 11, thus completing the limiting of the second insertion rod 9 and completing the installation of the top cover 5. At this time, the gas is delivered to the gas pipe 803 and the annular air bag 802 through the output end of the air pump 804, causing the annular air bag 802 to inflate until the outer side of the annular air bag 802 is tightly fitted with the inner cavity of the basket filter body 1 to prevent leakage. When it is necessary to remove the top cover 5, the lever 13 can be pulled again.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
