Description

Technical Field

[0001] This invention belongs to the field of refrigeration system technology, and in particular relates to a vertical siphon liquid receiver. Background Technology

[0002] A typical refrigeration system consists of two separate units: a liquid receiver and a siphon tank. The liquid receiver stores the condensed liquid, while the siphon tank, in addition to storing condensed liquid and supplying liquid to the oil cooler, also receives gas from the evaporator. Unevaporated liquid falls back down, and the gas re-enters the condenser. To supply liquid to the oil cooler, the siphon tank is usually placed at a high position, utilizing gravity to continuously supply liquid to the oil cooler and ensure its normal operation. A vertical siphon liquid receiver integrates the functions of both a liquid receiver and a siphon tank, essentially combining the functions of both into one unit.

[0003] Chinese utility model patent application number CN202321912747.5 discloses a vertical liquid receiver for a thermosiphon screw refrigeration unit, comprising a receiver cylinder divided into an upper auxiliary liquid receiver chamber and a lower main liquid receiver chamber by a horizontal partition. The upper auxiliary liquid receiver chamber has an inlet pipe on its side wall for receiving refrigerant liquid output from the evaporative condenser. The upper auxiliary liquid receiver chamber has an outlet on one side of its top to maintain pressure balance between the evaporative condenser and the upper auxiliary liquid receiver chamber. The upper auxiliary liquid receiver chamber has a return outlet on the other side of its top to receive refrigerant gas returned from the thermosiphon oil cooler. A lower liquid cylinder is provided on one side of the horizontal partition to guide the refrigerant liquid into the lower main liquid receiver chamber. Although the aforementioned vertical siphon liquid receivers are equipped with drain pipes at the bottom of the upper main liquid storage chamber, the lack of isolation or buffer between the inlet pipe and the drain pipe causes the flow of liquid entering through the inlet pipe to cause the debris, impurities, and other foreign matter deposited on the partition plate to spread again. Some of the spread debris, impurities, and other foreign matter will continue to be suspended in the upper auxiliary liquid storage chamber with the liquid flow and enter the external oil cooler with the liquid, thereby affecting the stable operation of the oil cooler and refrigeration system. Summary of the Invention

[0004] In view of this, the present invention aims to propose a vertical siphon liquid receiver to solve the problem that the lack of isolation or buffer between the inlet pipe and the drain pipe on the upper auxiliary liquid storage chamber of the existing vertical siphon liquid receiver makes it easy for debris, impurities and other foreign objects to spread due to liquid impact, which affects the stable operation of the oil cooler and refrigeration system.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A vertical siphon liquid storage device includes a tank and a partition plate disposed inside the tank, the partition plate dividing the tank into an upper siphon chamber and a lower liquid storage chamber; a return gas pipe and an outlet gas pipe communicating with the siphon chamber are provided above the tank, and a lower drain pipe and a lower sewage pipe communicating with the liquid storage chamber are provided below the tank, the lower drain pipe being disposed above the lower sewage pipe;

[0007] The partition member has a lower liquid pipe in the middle for connecting the siphon chamber and the storage chamber, and an annular groove for collecting sludge is provided on the edge of the partition member. The tank body has an upper drain pipe connected to the annular groove at the position below the partition member. The partition member has a receiving cavity inside, and a blocking ring is provided above the partition member. The blocking ring is coaxially arranged with the lower liquid pipe. The outer side of the blocking ring has a beveled part, and the beveled part has a plurality of filter holes for connecting the siphon chamber and the receiving cavity. The tank body has an upper drain pipe connected to the receiving cavity at the position below the partition member.

[0008] The tank body is provided with an inlet pipe at the position corresponding to the liquid inlet pipe, which communicates with the siphon chamber. A buffer component is provided on the tank body at the position corresponding to the liquid inlet pipe and the partition. The buffer component has a buffer ring that cooperates with the blocking ring on one side facing the partition, and a flow divider is provided on the other side corresponding to the position of the liquid inlet pipe. The buffer ring and the blocking ring are coaxially arranged, and the buffer ring is sleeved on the outside of the blocking ring. The buffer component has several liquid passage holes at the positions corresponding to the buffer ring around its perimeter. There are liquid passage gaps between the buffer ring and the inner wall of the tank, the partition, and the blocking ring. The liquid inlet pipe and the filter hole are connected to the liquid passage holes through the liquid passage gaps.

[0009] Furthermore, the buffer ring includes a vertical part, an inclined part, and a horizontal part connected in sequence. One end of the vertical part is connected to the buffer member, and the other end is connected to the inclined part. The inclined part is arranged corresponding to the inclined surface on the blocking ring, and the inclined part is arranged parallel to the inclined surface. The horizontal part is arranged parallel to the partition member. One end of the horizontal part is connected to the inclined part, and the other end is arranged above the annular groove.

[0010] Furthermore, the annular groove is coaxially arranged with the buffer ring.

[0011] Furthermore, the upper surface of the horizontal part is flush with the upper surface of the partition.

[0012] Furthermore, multiple liquid passage holes are arranged radially around the flow divider.

[0013] Furthermore, the liquid passage is inclinedly disposed on the buffer member, with the downward-sloping end of the liquid passage facing the buffer ring.

[0014] Furthermore, the flow divider is a conical structure, and the flow divider is coaxially arranged with the inlet pipe, with the conical end of the flow divider facing the inlet pipe.

[0015] Furthermore, the inner side of the blocking ring is provided with a recess that communicates with the lower liquid pipe.

[0016] Furthermore, the partition is also provided with a balance tube for connecting the siphon chamber and the liquid storage chamber. One end of the balance tube passes through the partition and the other end passes through the buffer. Vents are provided on the balance tube at the positions corresponding to the blocking ring and the buffer, and between the buffer and the liquid inlet pipe.

[0017] Compared with existing technologies, the vertical siphon liquid receiver of the present invention has the following advantages:

[0018] (1) The vertical siphon liquid receiver described in this invention has the advantages of stability and reliability. It integrates the functions of a liquid receiver and a siphon tank, making it more convenient to use and install. It reduces the installation space, making the refrigeration system more compact and beautiful, and is conducive to improving the stability and reliability of the refrigeration system operation.

[0019] (2) The vertical siphon liquid receiver of the present invention has a receiving cavity inside the partition and an upper drain pipe communicating with the receiving cavity on the partition. The receiving cavity can be used to collect liquid above the upper surface of the partition. After the liquid settles in the annular groove and the impurities are separated, it can also be filtered through the filter holes on the inclined part of the baffle ring, reducing the possibility of foreign objects entering the receiving cavity, thereby helping to prevent foreign objects from affecting the stability of the operation of the external oil cooler. In addition, by setting the filter holes on the inclined part of the baffle ring, the filter holes are less likely to be blocked, so that the filter holes can continuously and stably filter the liquid entering the receiving cavity, reducing the difficulty of using and maintaining this liquid receiver and improving the reliability of this liquid receiver in actual use.

[0020] (3) The vertical siphon liquid storage device of the present invention, by setting the inlet pipe to correspond to the outlet pipe, allows the liquid entering the siphon chamber through the inlet pipe to be fully dispersed by the diverter. The dispersed liquid can be further decelerated and dispersed by the buffer component. Then the liquid can continue to flow downward through the liquid hole. At this time, the buffer ring can separate the flowing liquid from the blocking ring, preventing liquid that may contain foreign matter from flowing directly to the blocking ring. At the same time, the buffer ring can also play a secondary blocking role on the flowing liquid, further reducing the flow velocity of the liquid, so that the liquid is more evenly dispersed on the surface of the partition component, thereby helping to improve the settling velocity of foreign matter in the liquid.

[0021] (4) The vertical siphon liquid storage device of the present invention, by sleeved a buffer ring on the outside of the blocking ring, not only provides a good shielding effect for the blocking ring, preventing liquid with foreign matter from flowing directly to the blocking ring, but also the curved liquid passage gap between the buffer ring and the blocking ring can further extend the liquid flow distance, which is conducive to the deposition of foreign matter.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] This invention provides a vertical siphon liquid receiver, such as... Figures 1 to 5As shown, the device includes a tank body 1 and a horizontally arranged partition 9 inside the tank body 1. The partition 9 divides the tank body 1 into an upper siphon chamber 10 and a lower liquid storage chamber 11. A return gas pipe 4 and an outlet gas pipe 5 communicating with the siphon chamber 10 are provided above the tank body 1. A lower drain pipe 2 and a lower sewage pipe 3 communicating with the liquid storage chamber 11 are provided below the tank body 1. The lower drain pipe 2 is arranged above the lower sewage pipe 3.

[0032] The aforementioned baffle 9, return pipe 4, outlet pipe 5, lower drain pipe 2, and lower drain pipe 3 can all be fixed to the tank body 1. The outlet pipe 5 allows gaseous refrigerant to flow out, mix with compressor exhaust, and then be liquefied again after passing through the condenser. The return pipe 4 can be used to recover the gas-liquid mixture from the oil cooler, achieving circulation. The lower drain pipe 2 can be used to discharge liquid refrigerant from the liquid storage chamber 11. The lower drain pipe 3 can be used to discharge debris, impurities, and other foreign matter from the bottom of the liquid storage chamber 11.

[0033] The partition 9 has a lower liquid pipe 13 in the middle for connecting the siphon chamber 10 and the storage chamber 11. The edge of the partition 9 has an annular groove 17 for collecting sludge. The tank body 1 has an upper drain pipe 8 connected to the annular groove 17 at a position corresponding to the lower part of the partition 9. The partition 9 has a receiving cavity 21 inside. The partition 9 has a blocking ring 12 above it. The blocking ring 12 is coaxially arranged with the lower liquid pipe 13. The outer side of the blocking ring 12 has a beveled part 19. The beveled part 19 has a plurality of filter holes 29 for connecting the siphon chamber 10 and the receiving cavity 21. The tank body 1 has an upper drain pipe 7 connected to the receiving cavity 21 at a position corresponding to the lower part of the partition 9.

[0034] For example, one end of the upper drain pipe 8 is fixed to the partition 9 and communicates with the annular groove 17, while the other end extends out of the tank 1 to discharge foreign objects from the siphon chamber 10. By providing the annular groove 17 on the partition 9, the annular groove 17 can effectively collect foreign objects in the refrigerant entering the siphon chamber 10, which helps to reduce the possibility of foreign object diffusion caused by liquid flow.

[0035] In practical applications, the baffle ring 12, the lower liquid pipe 13, and the upper liquid drain pipe 7 are all fixed on the partition plate, with the lower liquid pipe 13 vertically mounted on the partition plate 9. The upper liquid drain pipe 7 can be connected to an external oil cooler to absorb heat from the counter-flowing lubricating oil, causing a portion of the refrigerant liquid to vaporize after absorbing heat, thus cooling the lubricating oil. By providing a receiving cavity 21 inside the partition plate 9 and installing the upper liquid drain pipe 7 on the partition plate 9 that communicates with the receiving cavity 21, the receiving cavity 21 can collect liquid above the upper surface of the partition plate 9. The liquid settles in the annular groove 17, achieving impurity separation. Afterward, the liquid can be filtered through the filter holes 29 on the inclined surface 19 of the baffle ring 12, further reducing the possibility of foreign matter entering the receiving cavity 21, thereby helping to prevent foreign matter from affecting the stability of the external oil cooler's operation.

[0036] Furthermore, by setting the filter hole 29 on the inclined surface 19 of the blocking ring 12, the filter hole 29 is less prone to clogging, enabling the filter hole 29 to continuously and stably filter the liquid entering the receiving cavity 21, reducing the difficulty of using and maintaining this liquid reservoir, and improving the reliability of this liquid reservoir in actual use.

[0037] Above the tank body 1, corresponding to the position of the lower liquid pipe 13, there is an inlet pipe 6 communicating with the siphon chamber 10. The inlet pipe 6 and the lower liquid pipe 13 are coaxially arranged. A buffer member 22 is provided on the tank body 1 at the position between the inlet pipe 6 and the partition 9. A buffer ring 15 cooperating with the blocking ring 12 is provided on one side of the buffer member 22 facing the partition 9, and a diverter hood 16 is provided on the other side corresponding to the position of the inlet pipe 6. The buffer ring 15 and the blocking ring 12 are coaxially arranged, and the buffer ring 15 is sleeved on the outside of the blocking ring 12. Several liquid passage holes 14 are provided on the buffer member 22 at the position corresponding to the position of the buffer ring 15. There are liquid passage gaps 18 between the buffer ring 15 and the inner wall of the tank body 1, the partition 9, and the blocking ring 12. The lower liquid pipe 13 and the filter hole 29 are both connected to the liquid passage holes 14 through the liquid passage gaps 18.

[0038] For example, the inlet pipe 6 and the buffer element 22 are both fixedly mounted on the tank body 1, and the buffer ring 15 and the flow divider 16 are both fixedly mounted on the buffer element 22. By setting the inlet pipe 6 to correspond to the outlet pipe 13, the liquid entering the siphon chamber 10 through the inlet pipe 6 can be fully dispersed by the flow divider 16. The dispersed liquid can be further decelerated and dispersed by the buffer element 22. Then, the liquid can continue to flow downward through the liquid hole 14. At this time, the buffer ring 15 can separate the flowing liquid from the blocking ring 12, preventing liquid that may contain foreign objects from flowing directly to the blocking ring 12. At the same time, the buffer ring 15 can also play a secondary blocking role on the flowing liquid, further reducing the flow velocity of the liquid, so that the liquid is more evenly dispersed on the surface of the baffle 9, thereby helping to improve the settling velocity of foreign objects in the liquid.

[0039] Optionally, the buffer ring 15 includes a vertical portion 25, an inclined portion 26, and a horizontal portion 27 connected in sequence. One end of the vertical portion 25 is connected to the buffer member 22, and the other end is connected to the inclined portion 26. The inclined portion 26 is disposed corresponding to the inclined portion 19 on the blocking ring 12, and the inclined portion 26 is parallel to the inclined portion 19. One end of the horizontal portion 27 is connected to the inclined portion 26, and the other end is disposed above the annular groove 17. The annular groove 17 is coaxially disposed with the buffer ring 15.

[0040] For example, the annular groove 17 and the buffer ring 15 are coaxially arranged. By coaxially arranging the annular groove 17 and the buffer ring 15, the liquid falling onto the buffer ring 15 through the liquid hole 14 can flow into the annular groove 17 along the horizontal part 27 of the buffer ring 15. The position of flowing into the annular groove 17 will also be far away from the blocking member. This allows sufficient length and space for the sedimentation of foreign objects in the liquid, relatively increasing the distance of liquid flow and further reducing the possibility of foreign objects flowing with the liquid to the filter hole 29 of the blocking ring 12. This reduces the filtration pressure at the filter hole 29, prevents the filter hole 29 from becoming clogged after long-term use, and ensures that the liquid reservoir can work continuously and stably.

[0041] In practical applications, when the liquid level on the baffle 9 is higher than the upper surface of the baffle ring 12, the liquid can submerge the baffle ring 12 and flow into the storage chamber 11 through the lower liquid pipe 13. By sleeved the buffer ring 15 on the outside of the baffle ring 12, the buffer ring 15 not only provides a good shielding effect for the baffle ring 12, preventing liquid containing foreign matter from flowing directly to the baffle ring 12, but also the curved liquid passage gap 18 between the buffer ring 15 and the baffle ring 12 can further extend the liquid flow distance, which is beneficial for the deposition of foreign matter.

[0042] Optionally, the upper surface of the horizontal section 27 is flush with the upper surface of the partition member 9. By aligning the upper surface of the horizontal section 27 with the upper surface of the partition member 9, liquid can only enter the receiving cavity 21 within the partition member 9 through the filter hole 29 on the blocking ring 12 when the liquid level on the partition member 9 is higher than the upper surface of the horizontal section 27. Therefore, during the use of this liquid reservoir, a liquid film easily forms on the horizontal section 27. When liquid falls onto the horizontal section 27 through the liquid hole 14, the liquid film provides a good buffering effect, which not only helps to reduce the liquid flow rate but also helps to prevent further splashing, thus making it easier for foreign objects in the liquid to settle.

[0043] In practical applications, due to the blocking effect of the buffer ring 15, the liquid entering the siphon chamber 10 through the inlet pipe 6 easily forms a height difference between the inner and outer sides of the buffer ring 15. Under the action of pressure difference, it is beneficial to increase the flow rate of the liquid at the filter hole 29 on the inclined surface 19, thereby preventing the filter hole 29 from becoming clogged.

[0044] Specifically, by placing the inclined portion 26 on the buffer ring 15 close to the inclined portion 19 of the blocking ring 12 and making them parallel, the gap between the inclined portion 26 and the inclined portion 19 can be reduced, so that the liquid passage gap 18 forms a structure similar to a Venturi tube, that is, the width of the vertical portion 25 and the horizontal portion 27 is greater than the width of the inclined portion 26. In this way, when the liquid flows down the liquid pipe 13 through the liquid passage gap 18 at the horizontal portion 27, the liquid flow velocity at the inclined portion 26 will be accelerated, thereby playing a certain cleaning role on the filter holes 29 on the inclined portion 19, driving foreign objects on the surface of the filter holes 29 to flow down the liquid pipe 13, and finally flowing out of the tank 1 through the lower drain pipe 3, further reducing the possibility of the filter holes 29 becoming blocked during use.

[0045] Optionally, multiple liquid passage holes 14 are arranged radially around the flow divider 16. Specifically, the diameter of the liquid passage holes 14 closer to the flow divider 16 can be set smaller. By arranging multiple liquid passage holes 14 radially, the liquid can fall more evenly through the multiple liquid passage holes 14 during the process of liquid flow and diffusion along the surface of the buffer 22. The multiple liquid passage holes 14 can not only play a good role in slowing down and buffering the flowing liquid, but also make the liquid fall more dispersedly onto the lower baffle 9 or buffer ring 15, reducing the possibility of liquid splashing and ensuring that foreign objects in the liquid can be deposited quickly.

[0046] In practical applications, the liquid passage holes 14 are inclinedly arranged on the buffer member 22, with the downward-sloping end of the liquid passage holes 14 facing the buffer ring 15. By using inclined liquid passage holes 14, multiple liquid passage holes 14 can form several deceleration barbed groove structures on the surface of the buffer member 22, thereby better decelerating the liquid flowing along the surface of the buffer member 22 and reducing the liquid flow velocity. At the same time, by setting the downward-sloping end of the liquid passage holes 14 towards the buffer ring 15, the liquid flowing downward through the liquid passage holes 14 can also better contact the buffer ring 15, achieving secondary deceleration.

[0047] Optionally, the flow divider 16 is a conical structure, coaxially arranged with the inlet pipe 6, and the conical end of the flow divider 16 facing the inlet pipe 6. By adopting a conical structure, the flow divider 16 can better disperse the liquid flowing in through the inlet pipe 6, allowing the liquid to flow more evenly onto the surface of the buffer 22.

[0048] Optionally, the inner side of the baffle ring 12 is provided with a recess 20 that communicates with the drain pipe 13. By providing the recess 20 on the inner side of the baffle ring 12, the recess 20 can form a funnel-shaped opening, which expands the inlet area of ​​the drain pipe 13, which is beneficial for guiding the liquid into the drain pipe 13 and preventing the liquid from stagnating at the inlet of the drain pipe 13 and affecting the liquid flow rate. At the same time, the recess 20 can also form a transition with the inclined surface 19 on the outer side of the baffle ring 12, forming a smooth transition height difference between the baffle ring 12 and the drain pipe 13, which facilitates the rapid flow of liquid into the drain pipe 13 and avoids the decrease in liquid flow rate between the inclined surface 19 and the inclined portion 26, ensuring that the liquid flow can clean the filter holes 29 on the inclined surface 19.

[0049] Optionally, the partition 9 is further provided with a balance pipe 23 for connecting the siphon chamber 10 and the liquid storage chamber 11. One end of the balance pipe 23 passes through the partition 9, and the other end passes through the buffer member 22. The partition 9 is provided with a through hole 28 to facilitate the passage of the balance pipe 23. The balance pipe 23 is provided with vents 24 at positions corresponding to the positions between the blocking ring 12 and the buffer member 22, and between the buffer member 22 and the liquid inlet pipe 6. For example, the balance pipe 23 is fixed on the partition 9, with its lower end connected to the liquid storage chamber 11 and its upper end connected to the siphon chamber 10, to balance the pressure of the upper and lower chambers, which is more conducive to the flow of liquid refrigerant from the upper chamber into the lower chamber.

[0050] In practical applications, by setting vents 24 on the balance pipe 23 at the positions corresponding to the blocking ring 12 and the buffer 22, and between the buffer 22 and the inlet pipe 6, the balance pipe 23 can also balance the pressure of the upper and lower chambers of the buffer 22, so that the diameter of the buffer 22 can be designed to be the inner diameter of the tank 1 and fixed on the tank 1, thereby increasing the area of ​​the buffer 22, which is beneficial to improving the buffering and dispersion effect of the buffer 22 on the liquid entering through the inlet pipe 6.

[0051] This invention provides a vertical siphon liquid receiver, which offers advantages of stability and reliability. It integrates the functions of a liquid receiver and a siphon tank, making it more convenient to use and install, reducing installation space, and resulting in a more compact and aesthetically pleasing refrigeration system. It also improves the stability and reliability of the refrigeration system. By setting a receiving cavity inside the partition and installing an upper drain pipe communicating with the receiving cavity on the partition, the receiving cavity can collect liquid above the upper surface of the partition. After sedimentation in the annular groove, impurities are separated, and the liquid can be filtered through filter holes on the inclined surface of the baffle ring, reducing the possibility of foreign objects entering the receiving cavity. This helps prevent foreign objects from affecting the stability of the external oil cooler. Furthermore, by placing the filter holes on the inclined surface of the baffle ring, the filter holes are less prone to clogging, allowing them to continuously and stably filter the liquid entering the receiving cavity. This reduces the difficulty of using and maintaining this liquid receiver, and improves its reliability in actual use.
