Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically to a spray water filtration device for a roadheader. Background Technology

[0002] Due to repeated use, water supply pipes in coal mines often accumulate large amounts of coal sludge inside. During pipe connection and transport, coal dust and sludge can also enter the pipe walls. Since the water supply pipes are the source of the roadheader's spray system, this frequently leads to nozzle blockage, resulting in poor atomization and significant coal dust at the tunneling face, impacting production. Existing filters also eventually become clogged, and replacing them is inconvenient, requiring disassembly of multiple structures for maintenance, making the process cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a spray water filtration device for a roadheader, in order to solve the problems mentioned in the background art, such as the existing filter screen still clogging the spray after a certain period of time, and the inconvenience of replacing the filter screen, which requires disassembling many structures before the filter screen can be disassembled and maintained, making disassembly quite troublesome.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spray water filtration device for a roadheader, comprising:

[0005] Connect the straight pipe;

[0006] The inner fixing ring is located below the connecting straight pipe;

[0007] Connecting pipe No. 2 is located inside the inner fixing ring;

[0008] Water passage holes are equidistantly located inside the No. 2 connecting pipe;

[0009] A filter screen sleeve is installed on the outside of the second connecting pipe, and a closed base is fixed to the bottom of the filter screen sleeve.

[0010] As a preferred embodiment of this utility model, it further includes a fixing sleeve, which is fixedly connected to the bottom of the inner fixing ring. The outer side of the fixing sleeve is provided with an external threaded surface, and the outer side of the filter screen sleeve is provided with an internal threaded sleeve that mates with the external threaded surface.

[0011] As a preferred embodiment of this utility model: the inner side of the fixed sleeve is provided with a plurality of limiting inner grooves at equal intervals, and the outer side of the filter screen sleeve is fixed with a plurality of limiting outer blocks that cooperate with the limiting inner grooves at equal intervals.

[0012] As a preferred embodiment of this utility model: a top pressure ring that cooperates with multiple limiting outer blocks is fixedly connected to one side of the internal threaded sleeve, and multiple auxiliary rotating blocks are fixedly connected at equal intervals to the outer sides of the internal threaded sleeve and the top pressure ring.

[0013] As a preferred embodiment of this utility model, a No. 1 connecting pipe is fixedly connected to the top end of the connecting straight pipe.

[0014] As a preferred embodiment of this utility model: a No. 1 flange is fixedly connected to the bottom of the connecting straight pipe, and a No. 2 flange that mates with the No. 1 flange is fixedly connected to the outer side of the inner fixing ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a limiting outer block and limiting inner groove, realizes the positioning of the limiting outer block on the outside of the filter screen sleeve and each limiting inner groove on the inside of the fixed sleeve, and limits the installation of the filter screen sleeve on the outside of the No. 2 connecting pipe. The filter screen sleeve filters impurities in the water entering the water passage and the No. 2 connecting pipe. By setting an internal threaded sleeve and a top pressure ring, the internal threaded sleeve is threadedly installed on the external thread surface of the fixed sleeve. The top pressure ring at the bottom of the internal threaded sleeve presses down on the limiting outer block in each limiting inner groove, fixing the position of the filter screen sleeve and the closed chassis. It is also convenient to disassemble the filter screen sleeve when needed. Attached Figure Description
