Description

Technical Field

[0001] This utility model relates to a filtration system for heating pipelines, belonging to the field of heating technology. Background Technology

[0002] In heating systems, water or other heat transfer media circulate in pipes to transfer heat. However, these media may contain various impurities, such as particles, sediment, and rust. If these impurities are not filtered out, they can adversely affect the normal operation of the heating system. Therefore, installing a filtration device is essential to ensure the smooth operation of the heating system and extend its service life. The filtration device can intercept and remove impurities from the media, thereby protecting the various components of the heating system from damage.

[0003] There are various types of heating pipe filtration devices in the prior art, such as a heating pipe filtration device disclosed in patent number CN202021333782.8, a pipe filtration device for heating equipment disclosed in patent number CN202121403562.2, and a filtration device for heating pipes disclosed in patent number CN202322493265.7.

[0004] The technical solutions disclosed in the aforementioned patent documents still have the following technical problems in practice: the flow of heating water will be interrupted during the maintenance and replacement of the filter element, affecting normal delivery, and there is also the problem that the filter element is inconvenient to install, remove and fix.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A filtration system for heating pipelines includes two filter cylinders arranged side by side. Each filter cylinder has an inlet pipe and a drain pipe installed on its inner side facing each other. The inner ends of the inlet pipe between the two filter cylinders are connected to the left and right ports of an inlet three-way valve, and the side port of the inlet three-way valve is connected to an inlet pipe. The inner ends of the drain pipe between the two filter cylinders are connected to the left and right ports of a drain three-way valve, and the side port of the drain three-way valve is connected to a drain pipe.

[0009] A filter element is installed in the middle of the inner cavity of the filter cartridge, and the bottom of the filter element abuts against the support frame. A fixing rod is fixedly installed in the middle of the support frame, and the fixing rod passes through the filter element. The top of the fixing rod is engaged with the gland by a nut.

[0010] Furthermore, each filter cartridge is fitted with a cap on top.

[0011] Furthermore, the drain connection pipe is located directly above the inlet connection pipe.

[0012] Furthermore, both the inlet three-way valve and the drain three-way valve are electric three-way valves.

[0013] Furthermore, the support frame is arranged in a horizontal direction.

[0014] Furthermore, the support frame is fixed to the inner wall of the filter cylinder.

[0015] Furthermore, the top of the filter element is inserted through the bottom of the collecting hopper, which is in the shape of an inverted cone, and the top of the collecting hopper is fixed to the inner wall of the filter cylinder.

[0016] Furthermore, the side of the collecting hopper is fixedly connected to the drainage connecting pipe, and the inner cavities of the two are connected.

[0017] Furthermore, the bottom of the inner cavity of the filter cylinder is provided with an elliptical end cap, and a drain pipe is fixedly installed at the bottom of the elliptical end cap, with a drain valve installed on the drain pipe.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

Detailed Implementation

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a filtration system for heating pipelines, including two filter cylinders 1 arranged side by side, each of which is equipped with a cylinder cover 8 on its top.

[0027] Both filter cylinders 1 are equipped with an inlet pipe 2 and a drain pipe 5 on their opposing inner sides, with the drain pipe 5 located directly above the inlet pipe 2.

[0028] The inner ends of the water inlet connecting pipe 2 between the two filter cartridges 1 are connected to the left and right ports of the water inlet three-way valve 3, and the side port of the water inlet three-way valve 3 is connected to the water inlet pipe 4. The water inlet three-way valve 3 is an electric three-way valve used to control the direction of water flow.

[0029] The inner ends of the drain connecting pipe 5 between the two filter cartridges 1 are connected to the left and right ports of the drain three-way valve 6, and the side port of the drain three-way valve 6 is connected to the drain pipe 7. The drain three-way valve 6 is an electric three-way valve used to control the direction of water flow.

[0030] A filter element 9 is installed in the middle of the inner cavity of the filter cylinder 1, which is arranged vertically. The bottom of the filter element 9 abuts against the support frame 10 arranged horizontally, and the support frame 10 is fixed to the inner wall of the filter cylinder 1.

[0031] A fixing rod 11 is fixedly installed in the middle of the support frame 10 along the vertical direction. The fixing rod 11 passes through the filter element 9. The top of the fixing rod 11 is engaged with the pressure cap by a nut, which can press the filter element 9 on the support frame 10, making it convenient to install, remove and replace the filter element 9.

[0032] The top of the filter element 9 is inserted through the bottom of the collecting hopper 12, which is in the shape of an inverted cone. The top of the collecting hopper 12 is fixed to the inner wall of the filter cylinder 1.

[0033] The side of the collecting hopper 12 is fixedly connected to the drain connecting pipe 5, and the inner cavities of the two are connected. The collecting hopper 12 collects the filtered water and transports it into the drain connecting pipe 5.

[0034] The bottom of the inner cavity of the filter cylinder 1 is provided with an elliptical end cap, and a drain pipe 13 is fixedly installed at the bottom of the elliptical end cap. A drain valve is installed on the drain pipe 13.

[0035] The specific working principle of this utility model is as follows:

[0036] Heating water flows into the inner cavity of one of the filter cylinders 1 from the inlet pipe 4, the inlet three-way valve 3 and the inlet connecting pipe 2. After being filtered by the filter element 9, it enters the collecting hopper 12, the drain connecting pipe 5, the drain three-way valve 6 and the drain pipe 7 in sequence. The filtered impurities can be discharged through the sewage pipe 13.

[0037] This utility model features two filter cylinders 1 arranged side by side, each containing a filter element 9. When one filter element 9 needs maintenance and disassembly, the other filter element 9 is in operation, providing a backup function to prevent problems caused by the replacement of filter elements from affecting the normal delivery of heating water.

[0038] In this invention, the fixing rod 11 cooperates with the nut and the pressure cap to press the filter element 9 onto the support frame 10, which facilitates the installation, removal and replacement of the filter element 9.
