[0027] Reference Figure 1 to Figure 2 According to a first aspect of an embodiment of the utility model, a pipeline filtering device includes a tube body 100, a filter cartridge 210 and a sealing plate 300. The tube body 100 has a first channel 110. The two ends of the tube body 100 are respectively provided with a first open end 120 and a second open end 130 connected to the first channel 110. The side wall of the tube body 100 is provided with an outlet 140. The filter cartridge 210 is arranged in the first channel 110 along the length direction of the tube body 100. The filter cartridge 210 divides the first channel 110 into a second channel 111 directly connected to the first open end 120 and a third channel 112 directly connected to the second open end 130. The sealing plate 300 is detachably arranged at the first open end 120, wherein the outlet 140 is connected to the second channel 111, and the filter cartridge 210 can be taken out through the first open end 120. When in use, the fluid to be filtered enters the third channel 112 from the second opening end 130. Due to the cylindrical structure of the filter cartridge 210, its filtering area is large and not easy to be blocked. The fluid flows into the second channel 111 through the filter cartridge 210 and then flows out from the outlet 140. The filtered particles and impurities are accumulated in the filter cartridge 210. The accumulation space is large and the frequency of cleaning is low. When cleaning is needed, the sealing plate 300 can be removed to remove the filter cartridge 210 from the first opening end 120 for cleaning, which is convenient to disassemble.

[0028] Specifically, the tube body 100 can be a straight circular tube, the first channel 110 is a channel of the circular tube, the first open end 120 and the second open end 130 are directly connected, the side wall of the tube body 100 can be provided with an outlet 140, and a pipeline can be set at the outlet 140, and the whole is roughly in a three-way shape, the filter cartridge 210 can be a cylindrical filter screen, the filter cartridge 210 is inserted into the first channel 110 along the length direction of the tube body 100, the filter cartridge 210 divides the first channel 110 into a second channel 111 and a third channel 112, and the depth direction of the filter cartridge 210 is consistent with the flow direction of the fluid in the tube body 100, the second open end 130 can be connected to the module furnace, and water flows from the second open end 130 into the third channel 1 12, and then flows into the filter cartridge 210. Since the depth direction of the filter cartridge is consistent with the flow direction of the fluid in the tube body 100, impurities and particulate matter in the water can be accumulated in the filter cartridge 210, and the accumulation amount is large. The filtration area of ​​the filter cartridge 210 is much larger than that of the flat filter screen, so it is not easy to be blocked. After filtration, the water flows from the second channel 111 to the outlet 140. The outlet 140 can be connected to the module furnace. The second opening end 130 and the outlet 140 are arranged in the circulating water circuit to realize the filtration function, and the first opening end 120 can be used as an inspection port. The first opening end 120 can be opened by disassembling the sealing plate 300 to take out the filter cartridge 210 along the tube body 100, and the pipeline can be cleaned and maintained, and the operation is simple.

[0029] Reference Figure 2 In some embodiments of the present invention, one end of the filter cartridge 210 is connected to the inner wall of the tube body 100, and the other end is connected to the sealing plate 300. This makes it easy for operators to take out the filter cartridge 210.

[0030] Specifically, one end of the filter cartridge 210 can be fixedly connected to the tube body 100, and one end of the filter cartridge 210 and the inner wall of the tube body 100 can be provided with threads, so that the filter cartridge 210 can be threadedly connected to the inner wall of the tube body 100, and the other end of the filter cartridge 210 can be fixedly connected to the sealing plate 300, and welding, clamping and other connection methods can be adopted, which are not described in detail. The filter cartridge 210 can be taken out by operating the external sealing plate 300, and there is no need to take the filter cartridge 210 in the pipeline, which is convenient to operate.

[0031] In some embodiments of the present invention, the filter cartridge 210 is cone-shaped, and the large end of the filter cartridge 210 is connected to the inner wall of the tube body 100. When water flows through, the cone-shaped structure can guide the water flow to flush impurities on the tube wall and reduce the occurrence of blockage.

[0032] Specifically, the filter cartridge 210 can be made into a cone shape using a filter mesh, and its diameter can gradually decrease in the direction approaching the blind plate. The filtering surface of the cartridge wall has an inclination, which can change the direction of the water flow. When water flows through, the cartridge wall of the filter cartridge 210 guides the fluid to flow along the cartridge wall, which can flush out impurities on the cartridge wall and further reduce the occurrence of blockage.

[0033] It should be noted that the shape of the filter cartridge 210 is not limited to the above embodiment, and other embodiments may also be adopted. For example, the filter cartridge 210 may also be in other shapes such as a triangle, as long as it has an inclined surface.

[0034] In some embodiments of the utility model, the pipe body 100 is provided with a first pipe section 150 and a second pipe section 160 connected to each other, the end of the first pipe section 150 away from the second pipe section 160 is a first open end 120, the end of the second pipe section 160 away from the first pipe section 150 is a second open end 130, the minimum inner diameter of the first pipe section 150 is greater than the minimum inner diameter of the second pipe section 160, and the filter cartridge 210 is located in the first pipe section 150. It can increase the storage volume of filtered impurities, reduce the frequency of disassembly and cleaning, and facilitate the disassembly of the filter cartridge 210.

[0035] Specifically, the tube body 100 can be machined, the inner diameter of the first tube segment 150 can be processed to be larger, and the inner diameter of the second tube segment 160 can be processed to be smaller. A filter cartridge 210 is arranged in the first tube segment 150. Since the cavity of the first tube segment 150 is larger, the size of the filter cartridge 210 can be set larger, and the accumulated filtered impurities can be increased. At the same time, the filtering area is increased, and it is not easy to be blocked, which further reduces the frequency of disassembly and cleaning. In addition, the first tube segment 150 with a larger inner diameter can also facilitate the disassembly of the filter cartridge 210.

[0036] It is understandable that the tube body 100 can also be formed into the first tube section 150 and the second tube section 160 by stamping.

[0037] Reference Figure 2 In some embodiments of the present invention, a reducer 151 is provided at one end of the first pipe section 150 away from the sealing plate 300, and the reducer 151 is connected to the second pipe section 160. One end of the filter cartridge 210 abuts against the inner wall of the reducer 151, and the other end abuts against the sealing plate 300. This can further facilitate the assembly and disassembly of the filter cartridge 210.

[0038] Specifically, the two ends of the reducer 151 match the pipe diameters of the first pipe section 150 and the second pipe section 160, and can be connected by welding. By setting the reducer 151, a smooth transition can be achieved from the first pipe section 150 to the second pipe section 160, which can reduce dead angles and reduce the accumulation of impurities. At the same time, the two ends of the filter cartridge 210 can be set as flat cross-sections, one end directly abuts against the inner wall of the reducer 151, and the other end abuts against the inner wall of the sealing plate 300. The sealing plate 300 and the tube body 100 can be connected by fasteners. During installation, the filter cartridge 210 is inserted into the first pipe section 150, and then the filter cartridge 210 is pressed against the inner wall of the reducer 151 when connected using the sealing plate 300. The operation is simple, and it can further facilitate the disassembly and assembly of the filter cartridge 210.

[0039] It is understandable that the filter cartridge 210 may have a certain elasticity, and the filter cartridge 210 pushed by the sealing plate 300 during connection may produce a certain amount of deformation to seal the variable diameter inner wall and the sealing plate 300 .

[0040] Reference Figure 2 In some embodiments of the present invention, the filter cartridge 210 includes a straight tube portion 211 and a conical portion 212. The conical portion 212 is disposed at one end of the straight tube portion 211 close to the sealing plate 300, and the diameter of the conical portion 212 decreases in the direction close to the sealing plate 300. This can increase the amount of impurities stored and also play a flushing role to reduce the occurrence of blockage.

[0041] Specifically, the filter cartridge 210 can be spliced ​​with a straight filter screen and a conical filter screen to form a straight portion 211 and a conical portion 212. The two components can be connected by welding or directly stamped. The straight portion 211 can increase the amount of impurities accumulated, while the conical portion 212 can form an inclined surface to guide the fluid to flush the wall of the conical portion 212. The combination of the straight portion 211 and the conical portion 212 can not only increase the amount of impurities accumulated, but also play a guiding and flushing role to reduce the occurrence of blockage.

[0042] It is understandable that the cone portion 212 may also be manufactured into other shapes as long as it has an inclined surface capable of guiding water flow.

[0043] Reference Figure 2 In some embodiments of the present invention, the filter cartridge 210 further includes an elastic member 220, and an elastic member 220 is disposed between the cone portion 212 and the sealing plate 300. The sealing effect can be improved, and a buffering and protective effect can be provided to the filter cartridge 210.

[0044] Specifically, the elastic member 220 can be a member made of elastic material, such as rubber, silicone, etc. When the sealing plate 300 is connected to the tube body 100, the elastic member 220 is pressed against the end of the cone portion 212. The elastic force generated by the elastic deformation drives the straight tube portion 211 to be pressed against the inner wall of the variable diameter, making the contact tighter, thereby improving the sealing effect. In addition, since the filter cartridge 210 is made of a filter screen, its structural strength is relatively low. Through the buffering of the elastic member 220, the damage to the filter cartridge 210 can also be reduced.

[0045] Reference Figure 2 In some embodiments of the present invention, the elastic member 220 is a spring, one end of which abuts against the sealing plate 300, and the other end abuts against the end surface of the cone portion 212. Specifically, the elastic member 220 can be a spring, which is a standard part, easy to produce and purchase, easy to replace and use, and can reduce the cost of use.

[0046] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the sealing plate 300 is provided with a first flange 310, the first opening end 120 is provided with a second flange 121, the first flange 310 and the second flange 121 are connected by fasteners, and the second opening end 130 is provided with a third flange 131. Specifically, the sealing plate 300 can be connected with the first opening end 120 by a flange and bolts, so that it is connected and sealed with the first opening end 120, and a gasket can be provided between the sealing plate 300 and the first opening end 120 to improve the sealing effect. The modular furnace can be provided with a flange corresponding to the third flange 131. By providing a flange connection, the filter device can be easily disassembled and assembled.

[0047] It should be noted that the first flange 310 , the second flange 121 and the third flange 131 are not limited to the above embodiments, and other embodiments may also be adopted. For example, they may be connected by fasteners such as clamps or threaded fasteners.

[0048] According to the second aspect of the present invention, a modular furnace includes a modular furnace using the above-mentioned pipeline filtering device. By using the above-mentioned pipeline filtering device, the circulating water of the modular furnace can be filtered, and the filtering device occupies a small space, the structure of the modular furnace is more compact, and the circulating water pipeline is not easy to be blocked during filtering, and the frequency of disassembly and cleaning is low, which is convenient for the use and maintenance of the modular furnace.
