Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of heating pipeline filtering and decontamination device. BACKGROUND

[0002] Heating pipeline is used to provide heating for users, and a filter is installed on the heating pipeline to filter water. After long-term use of the filter, impurities may accumulate and gradually block the filter screen. Currently, the filter needs to be disassembled for cleaning, and then reassembled after cleaning. This cleaning method is inefficient and seriously affects the heating. SUMMARY

[0003] The utility model aims at solving the above-mentioned technical problems, and provides a kind of heating pipeline filtering and decontamination device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A kind of heating pipeline filtering and decontamination device, its composition includes water inlet pipe, water outlet pipe and filter, the filter is externally fixed with support, the support is fixed with speed reducer motor, the output end of the speed reducer motor is fixed with reciprocating screw rod, the reciprocating screw rod is sleeved with sliding sleeve, the sliding sleeve is fixed with water inlet cavity pipe, the bottom of the water inlet cavity pipe is fixed with crescent cleaner through the shell of the filter.

[0006] The crescent cleaner includes a crescent water cavity, and two groups of brushes are fixed at the arc segments of the crescent water cavity.

[0007] The water inlet cavity pipe is an L-shaped pipe, the vertical end of which is a hollow pipe, and the horizontal end is a solid pipe.

[0008] The support is fixed with a limiting rod, and the limiting rod passes through the through hole of the water inlet cavity pipe. Advantages

[0009] 1. The utility model discloses a crescent cleaner, which is driven to move up and down by the reciprocating screw rod. The brushes of the crescent cleaner can brush off the impurities on the filter screen. The water sprayed from the water spray nozzles during the brushing process can flush away the brushed-off impurities. The flushed-away impurities are discharged through the drain pipe. The filter can be cleaned without disassembly, improving the cleaning efficiency. BRIEF DESCRIPTION OF DRAWINGS

Specific implementation

[0017] Referring to Figures 1-6 As shown in the figure, a heat supply pipeline filtering and decontamination device, its composition includes water inlet pipe 1, water outlet pipe 5 and filter 3, the filter is externally fixed with support 12, the support is fixed with speed reducer 17, the output end of the speed reducer is fixed with reciprocating screw 10, the reciprocating screw is connected with support through bearing, the reciprocating screw is sleeved with sliding sleeve 9, the sliding sleeve is fixed with water inlet cavity pipe 11, the bottom of the water inlet cavity pipe is fixed with crescent cleaner 13 through the shell 19 of the filter.

[0018] By starting the speed reducer, the speed reducer drives the reciprocating screw to rotate, the reciprocating screw cooperates with the sliding sleeve to drive the sliding sleeve to move up and down, the water inlet cavity pipe is L-shaped pipe, the vertical end is hollow pipe, and the horizontal end is solid pipe, the support is fixed with limit rod 8, the limit rod passes through the through hole of the water inlet cavity pipe, the bottom of the water inlet cavity pipe is fixed with crescent cleaner through the shell of the filter, the movement of the sliding sleeve makes the crescent cleaner move up and down, so that the filter screen 16 in the cleaner is brushed and washed.

[0019] The crescent cleaner includes crescent water cavity 20, two groups of brushes 14 are fixed at the arc segment of the crescent water cavity, and a plurality of water jets 15 are arranged between the two groups of brushes.

[0020] Working principle: close the water inlet valve 2 on the water inlet pipe 1, close the water outlet valve 4 on the water outlet pipe 5, open the sewage valve 7 on the two sewage pipes 6, start the speed reducer, the speed reducer drives the reciprocating screw rod to rotate, the reciprocating screw rod cooperates with the sliding sleeve to drive the sliding sleeve to move up and down, the water inlet cavity pipe is L-shaped pipe, the bottom of the water inlet cavity pipe passes through the shell of the filter and is fixed with the crescent cleaner, the movement of the sliding sleeve makes the crescent cleaner move up and down, water is supplied in the water inlet cavity pipe, the water is pressure water, the water enters the crescent water cavity, is sprayed out through the water outlet of the crescent water cavity, the sprayed water washes the sundries on the filter screen, at the same time, two groups of brushes are fixed on the crescent cleaner, the brushes brush and wash the filter screen, the sundries washed away are discharged through the sewage pipe, at the same time, part of the water sprayed out through the water outlet will pass through the filter screen, the sewage passing through the filter screen will be discharged through the sewage pipe on the other side, realizing the complete discharge of the sewage.
