Technical Field

[0001] The present application relates to the technical field of steam filtration, and specifically discloses a steam filtration device. Background Art

[0002] Steam filter is an indispensable device on the pipeline for conveying medium. Steam filtration is used in the fields of petroleum, chemical industry, medicine, environmental protection, water treatment, etc. Its principle is to filter the impurities contained in the steam in the pipeline through the filter element, so as to ensure the use requirements of the steam in the next process.

[0003] In the chemical production process, steam is often used as a medium for heating and heat transfer. However, steam contains impurities such as particles, debris and harmful substances, and needs to be filtered before it can be put into production. Therefore, a steam filter device is usually set in front of the steam input end of the production equipment to filter the steam. The existing steam filter device usually includes a filter tube and a filter screen arranged in the filter tube. However, as the steam filter works and operates, the impurities on the filter screen will gradually accumulate and form a blockage, affecting the normal supply of steam and the normal operation of chemical production. Therefore, in view of this, the inventor provides a steam filter device to solve the above problem. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a steam filtering device, including a filter tube detachably connected to a chemical production equipment, a filter screen arranged in the filter tube and a filter element detachably connected to one side of the filter tube, a guide tube is provided on one side of the filter tube inclined downward, an air guide tube is provided between the bottom of one end of the guide tube away from the filter tube and the side of the filter tube located below the filter screen, the filter element is detachably connected to the guide tube, the filter element includes a mounting head, a limit baffle and a core barrel fixed in sequence, the limit baffle is detachably connected to the end of the guide tube, the free end of the core barrel is connected to the interior of the filter tube, the bottom of the free end of the core barrel is connected to the filter screen, and a plurality of filter holes are evenly arranged on the circumference of the core barrel.

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the prior art, the utility model provides a connection between the filter element and the filter screen, so as to facilitate the filtering and guiding of impurities filtered on the filter screen into the filter element in the guide tube. By utilizing the connecting channel formed between the filter element, the air guide tube and the filter tube, not only the double filtration of steam is realized, and the quality of steam is improved, but also the accumulation of impurities on the filter screen is prevented, and the blockage inside the pipeline is avoided. The detachable sealing connection between the filter element and the guide tube is convenient for disassembly, and the impurities in the filter element are convenient for irregular unloading.

[0018] A steam filtering device, for example Figure 1 As shown: it includes a filter tube 1 with both ends sealed and detachably connected to the chemical production equipment, a filter screen 2 arranged in the filter tube 1 and used to filter steam, and a filter element 3 detachably connected to the right side of the filter tube 1. A guide tube 4 is arranged on the right side of the filter tube 1, and an air guide tube 5 is arranged between the bottom of the right end of the guide tube 4 and the side of the filter tube 1 below the filter screen 2. The filter element 3 is detachably connected to the guide tube 4. Figure 2 As shown, the filter element 3 includes a mounting head 6, a limit baffle 7 and a core tube 8 which are fixedly connected in sequence. The limit baffle 7 is sealed and detachably connected to the end of the guide tube 4, as shown in FIG. Figure 1 As shown, the left end of the core tube 8 is connected to the interior of the filter tube 1, and the bottom of the left end of the core tube 8 is connected to the filter screen 2. Figure 1 and Figure 2 As shown, a large number of filter holes 9 for filtering steam are evenly arranged on the circumference of the core cylinder 8.

[0019] Specifically, Figure 1 As shown, the filter screen 2 is tilted downward from left to right, and the filter screen 2 and the guide tube 4 are arranged in the same direction and in a colinear manner. Figure 2 As shown, the left end of the core cartridge 8 is an inclined arc-shaped structure adapted to the inner wall of the filter cartridge.

[0020] Specifically, Figure 1 and Figure 2 As shown, the outer circumferential side of the right end of the core barrel 8 is provided with an external thread structure 14, as shown in FIG. Figure 1 As shown, the inner wall of the right end of the guide cylinder is provided with an internal thread structure, the core cylinder 8 is detachably connected to the guide cylinder thread, and a limit plate 10 is provided on the outer side of the right end of the guide cylinder.

[0021] In the specific implementation process of the utility model, the two ends of the filter tube 1 are connected and installed with the chemical production equipment respectively, and then steam is input into the chemical production equipment to start production. When steam is passed into the filter tube 1, on the one hand, the steam directly passes through the filter screen 2, and the impurities in the steam are blocked on the filter screen 2, completing the filtration of the steam. At this time, the impurities roll down into the core barrel 8 along the inclined direction of the filter screen 2, and continue to roll and gather at the rightmost end of the core barrel 8 along the inclined direction of the core barrel 8 and gradually accumulate.

The impurities in the steam are directly blocked in the core tube 8, and the steam is passed back to the filter tube 1 through the air guide tube 5, which can also complete the steam filtering.

[0023] Compared with the prior art, the utility model provides a connection between the filter element 3 and the filter screen 2, so as to facilitate the filtering of impurities filtered on the filter screen 2 into the filter element 3 in the guide tube 4, and utilizes the connecting channel formed by the core tube 8, the air guide tube 5 and the filter tube 1, which not only realizes the double filtration of steam and improves the quality of steam, but also prevents the accumulation of impurities on the filter screen 2 and avoids the blockage inside the pipeline. Through the sealed connection between the limit baffle 7 and the limit plate 10, and the threaded connection between the external thread structure 14 of the core tube 8 and the internal thread structure of the guide tube, disassembly is convenient, and the irregular unloading of impurities in the filter element 3 is convenient, which solves the problem that in the traditional steam filtration process, the filter screen is easily accumulated with impurities and causes blockage, thereby affecting the steam supply and the operation of chemical production.
