Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a structure that avoids the phenomenon of cavities inside the equipment. Background Technology

[0002] Graphite heat exchangers are heat exchangers whose heat transfer components are made of graphite. Graphite heat exchangers have good corrosion resistance, are not prone to scaling on the heat transfer surface, and have good heat transfer performance. However, graphite is brittle and has low bending and tensile strength, so it can only be used in low-pressure applications, even the block porous structure with the best pressure-bearing capacity.

[0003] After investigation, it was found that during the use of graphite heat exchangers, liquid enters from the inlet and exits from the outlet. There is a height difference between the outlet and the top of the graphite heat exchanger pipes. If the water pressure is insufficient or the water supply pipe is too long, resulting in insufficient pressure, a cavity will form at the top of the graphite heat exchanger pipes. The liquid cannot fill the graphite heat exchanger pipes, thus affecting the efficiency of the equipment.

[0004] There is an urgent need for a structure that avoids the phenomenon of cavities inside the equipment to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a structure that avoids the phenomenon of cavities inside equipment, so as to solve the problem of easy formation of cavities inside equipment mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structure to avoid the phenomenon of internal cavities in equipment, comprising a graphite tube array, an inlet pipe fixedly connected to the bottom left side of the graphite tube array, an outlet pipe fixedly connected to the top right side of the graphite tube array, a connecting pipe installed on the right side of the outlet pipe, a filter cylinder installed between the connecting pipe and the outlet pipe, a telescopic pipe installed at the top of the connecting pipe, a drain pipe installed at the top of the telescopic pipe, a first mounting flange fixedly connected to the bottom of the telescopic pipe, a second mounting flange fixedly connected to the top of the telescopic pipe, a filter screen plate installed inside the filter cylinder, a fixing plate fixedly connected to the left side of the first mounting flange, and an adjusting screw movably connected to the top of the fixing plate.

[0007] Preferably, mounting bolts are installed on the connecting pipe, the filter cylinder, and the drain pipe, with the drain pipe positioned above the connecting pipe.

[0008] Preferably, the drain pipe is at a higher horizontal level than the outlet pipe, and the drain pipe and the outlet pipe are parallel to each other.

[0009] Preferably, a threaded ring is fixedly connected to the left side of the second mounting flange, and the threaded ring is threaded around the outside of the adjusting screw.

[0010] Preferably, the adjusting screw is located on the left side of the telescopic tube, and a throttle is fixedly connected to the top of the adjusting screw.

[0011] Preferably, the filter screen is externally fixedly connected with splicing blocks, and the filter cylinder is internally provided with splicing slots.

[0012] Preferably, the splicing card blocks are provided in three sets, and the splicing card blocks are embedded inside the splicing card slots.

[0013] Preferably, the filter cartridge is installed at the outlet of the water outlet pipe by mounting bolts, and the connecting pipe is connected to the outlet of the filter cartridge.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the structure that avoids the phenomenon of cavity in the equipment not only realizes the function of avoiding cavity formation and makes it easy to adjust and use, but also realizes the function of easy filtration;

[0015] (1) By setting up a drain pipe, a telescopic pipe and a connecting pipe, during the use of the graphite heat exchanger, water can enter the inside of the pipe from the inlet pipe of the graphite tube. A connecting pipe and a drain pipe are installed at the outlet pipe. The height of the drain liquid level of the drain pipe is greater than the height of the graphite tube overall pipe. When the water is discharged from the inside of the graphite tube, it can fill the graphite tube due to the water pressure difference, thus avoiding the formation of a cavity at the top of the graphite tube. This solves the problem of cavity formation in the pipe. Even if the equipment water supply pressure is insufficient or the pipe is long, the cavity can still be avoided by increasing the outlet liquid level. This structure realizes the function of avoiding cavity formation.

[0016] (2) By setting a fixed plate, adjusting screw, throttle, telescopic pipe, first mounting flange, threaded ring and second mounting flange, the horizontal height of the drain pipe can be flexibly adjusted according to the size of the graphite tube. When adjusting, just hold the throttle and turn the adjusting screw. The threaded ring on the outside of the adjusting screw can drive the telescopic pipe to move up and down, thereby changing the horizontal height of the drain pipe. This structure realizes the function of easy and flexible adjustment.

[0017] (3) By setting up a filter cylinder, splicing slot, filter screen plate and splicing block, the filter cylinder is installed between the water outlet pipe and the connecting pipe. The filter screen plate inside the filter cylinder can prevent scale and impurities that may exist in the graphite tube from entering the interior of the connecting pipe and causing blockage. The filter screen plate inside the filter cylinder can be disassembled for cleaning. When cleaning, first separate the filter cylinder from the water outlet pipe, and then take the filter screen plate out from the inside of the filter cylinder. The splicing block on the filter screen plate can be removed from the splicing slot. This structure realizes the function of easy filtration and cleaning. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-3 A structure to avoid the phenomenon of cavity inside the equipment includes a graphite tube 2, an inlet pipe 1 fixedly connected to the bottom left side of the graphite tube 2, an outlet pipe 3 fixedly connected to the top right side of the graphite tube 2, a connecting pipe 10 installed on the right side of the outlet pipe 3, a filter cylinder 11 installed between the connecting pipe 10 and the outlet pipe 3, a telescopic pipe 8 installed at the top of the connecting pipe 10, a drain pipe 7 installed at the top of the telescopic pipe 8, a first mounting flange 9 fixedly connected to the bottom of the telescopic pipe 8, a second mounting flange 13 fixedly connected to the top of the telescopic pipe 8, a filter screen plate 15 installed inside the filter cylinder 11, a fixing plate 4 fixedly connected to the left side of the first mounting flange 9, and an adjusting screw 5 movably connected to the top of the fixing plate 4.

[0024] Mounting bolts 17 are installed on the connecting pipe 10, the filter cylinder 11 and the drain pipe 7. The drain pipe 7 is located above the connecting pipe 10. The horizontal height of the drain pipe 7 is higher than that of the outlet pipe 3. The drain pipe 7 and the outlet pipe 3 are parallel.

[0025] Specifically, such as Figure 1 and Figure 2As shown, water can enter the pipeline from the inlet pipe 1 of the graphite tube 2. A connecting pipe 10 and a drain pipe 7 are installed at the outlet pipe 3. The liquid level of the drain pipe 7 is greater than the overall height of the graphite tube 2. When water is discharged from the inside of the graphite tube 2, it can fill the graphite tube 2 due to the water pressure difference, thus preventing the formation of cavities at the top of the graphite tube 2. This solves the problem of cavities in the pipeline. Even if the equipment has insufficient water supply pressure or the pipeline is long, the existence of cavities can still be avoided by increasing the outlet liquid level.

[0026] Example 2: A threaded ring 12 is fixedly connected to the left side of the second mounting flange 13. The threaded ring 12 is threaded around the outside of the adjusting screw 5. The adjusting screw 5 is located on the left side of the telescopic tube 8. A handle 6 is fixedly connected to the top of the adjusting screw 5. A splicing block 16 is fixedly connected to the outside of the filter screen plate 15. A splicing groove 14 is provided inside the filter cylinder 11.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, the horizontal height of the drain pipe 7 can be flexibly adjusted according to the size of the graphite tube 2. When adjusting, simply hold the handle 6 and turn the adjusting screw 5. The threaded ring 12 on the outside of the adjusting screw 5 can drive the telescopic pipe 8 to move up and down, thereby changing the horizontal height of the drain pipe 7.

[0028] Example 3: Three sets of splicing blocks 16 are provided. The splicing blocks 16 are embedded in the splicing slots 14. The filter cylinder 11 is installed at the outlet of the water outlet pipe 3 by mounting bolts 17. The connecting pipe 10 is connected to the outlet of the filter cylinder 11.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the filter screen 15 inside the filter cylinder 11 can prevent scale and impurities that may exist in the graphite tube 2 from entering the interior of the connecting pipe 10 and causing blockage. The filter screen 15 inside the filter cylinder 11 can be disassembled for cleaning. When cleaning, first disconnect the filter cylinder 11 from the water outlet pipe 3, and then remove the filter screen 15 from the inside of the filter cylinder 11. The splicing clip 16 on the filter screen 15 can be removed from the splicing slot 14.

[0030] Working principle: When using this utility model, the connecting pipe 10 needs to be installed on the outlet pipe 3 of the graphite tube 2 first. The filter cylinder 11 is installed between the outlet pipe 3 and the connecting pipe 10. The filter screen 15 inside the filter cylinder 11 can prevent scale and impurities that may exist in the graphite tube 2 from entering the interior of the connecting pipe 10 and causing blockage. The horizontal height of the drain pipe 7 can be flexibly adjusted according to the size of the graphite tube 2. When adjusting, simply hold the handle 6 and turn the adjusting screw 5. The threaded ring 12 on the outside of the adjusting screw 5 can drive the telescopic pipe 8 to move up and down, thereby changing the height of the drain pipe 7. At a certain height, water can enter the pipeline from the inlet pipe 1 of the graphite tube 2. A connecting pipe 10 and a drain pipe 7 are installed at the outlet pipe 3. The liquid level of the drain pipe 7 is greater than the overall height of the graphite tube 2. When water is discharged from the inside of the graphite tube 2, it can fill the graphite tube 2 due to the water pressure difference, thus preventing the formation of cavities at the top of the graphite tube 2. This solves the problem of cavities in the pipeline. Even if the water supply pressure of the equipment is insufficient or the pipeline is long, the existence of cavities can still be avoided by increasing the outlet liquid level. This structure achieves the function of preventing the formation of cavities.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
