Description

TECHNICAL FIELD

[0001] The utility model relates to refrigerant pump technical field, especially a kind of anti-vortex device and liquid accumulator. BACKGROUND

[0002] The refrigerant pump can be widely applied in refrigeration system, heat pump system and air conditioning system and other fields. The rotor pump of the refrigerant pump includes motor, crankshaft, upper cylinder cover, blade, lower cylinder cover, cylinder, pump body bolt and shell and other components. When the refrigerant pump works, the crankshaft drives the piston and the blade to move, the movement of the piston makes the volume formed by the piston, the upper cylinder cover, the lower cylinder cover, the blade and the cylinder change, so as to compress the refrigerant, so that the refrigerant obtains certain pressure and discharges the refrigerant pump.

[0003] However, due to insufficient pressure of the liquid discharged from the liquid accumulator (i.e. insufficient outlet pressure of the liquid accumulator), or unreasonable setting angle of the liquid discharge pipeline of the liquid accumulator, the refrigerant discharged from the liquid accumulator may generate vortex after being discharged. Once vortex is formed, it will cause insufficient suction of the refrigerant pump, reduce the amount of refrigerant entering the compression chamber of the refrigerant pump, reduce the flow and lift of the refrigerant pump, and further reduce the efficiency of the refrigerant pump. In addition, the vortex of the refrigerant discharged from the liquid accumulator is too large, which will also cause vibration or noise of the refrigerant pump, threaten the stable operation of the equipment, and even cause accidents.

[0004] Therefore, for those skilled in the art, how to design a liquid accumulator that can avoid vortex of refrigerant after being discharged from the liquid accumulator is a technical problem to be solved at present. UTILITY MODEL CONTENTS

[0041] The utility model will be described in detail below in combination with the drawings and preferred embodiments. In the case of no conflict, the following embodiments and features in the embodiments can be supplemented or combined with each other.

[0042] Referring to Figure 1 As shown in the figure, the utility model provides a kind of anti-vortex device 1 for being fixed at the liquid outlet 21 of liquid reservoir 2, and liquid reservoir 2 is used to be connected with refrigerant pump 3, and provide refrigerant to refrigerant pump 3. Anti-vortex device 1 is arranged at the liquid outlet 21 of liquid reservoir 2, can prevent the liquid state refrigerant in liquid reservoir 2 from forming vortex at the liquid outlet 21 of liquid reservoir 2 to reduce the refrigerant flow entering refrigerant pump 3, avoid the efficiency of refrigerant pump to decline.

[0043] Referring to Figure 1 As shown in the figure, anti-vortex device 1 includes support frame 11, mounting seat 12 and spoiler 13, support frame 11 is used to be fixed in liquid reservoir 2, mounting seat 12 is arranged below support frame 11 or mounting seat 12 is placed above the bottom of support frame 11 via the opening on support frame 11, and is fixedly connected with support frame 11. Spoiler 13 is fixed below mounting seat 12, and is used to prevent liquid (i.e. liquid state refrigerant) from forming vortex below mounting seat 12.

[0044] Referring to Figure 1 As shown in the figure, the utility model provides a kind of liquid reservoir, including shell 22 and anti-vortex device 1, anti-vortex device 1 is used to be fixed at the liquid outlet 21 of liquid reservoir 2, and support frame 11 is used to be fixed on the shell 22 of liquid reservoir 2. Optionally, support frame 11 can be fixed by welding with the inner wall of the shell 22 of liquid reservoir 2 to realize the fixation of the position of support frame 11.

[0045] Specifically, referring to Figure 1As shown, when the mounting base 12 is arranged below the support frame 11, the lower surface of the support frame 11 and the outer shell 22 of the liquid reservoir 2 enclose a containing space 4 for accommodating the mounting base 12 and the spoiler 13; when the mounting base 12 is placed above the bottom of the support frame 11 via the opening on the support frame 11, the lower surface of the support frame 11 and the outer shell 22 of the liquid reservoir 2 enclose a containing space 4 for accommodating the spoiler 13.

[0046] The present application provides a vortex prevention device and a liquid reservoir. The vortex prevention device 1 is arranged in the liquid reservoir 2 near the liquid outlet 21. The vortex prevention device 1 has a spoiler 13 which is fixed in the liquid reservoir 2 by a support frame 11 and a mounting base 12. After the liquid refrigerant enters the containing space 4 below the support frame 11, the circumferential movement speed of the liquid refrigerant in the liquid reservoir 2 can be reduced due to the blocking of the spoiler 13, so that vortex is less likely or even not likely to occur when the liquid refrigerant flows from the liquid reservoir 2 into the housing of the refrigerant pump 3, thereby improving the flow rate and lift of the refrigerant pump 3, improving the working efficiency of the refrigerant pump 3, and improving the service life and performance of the refrigerant pump 3.

[0047] Referring to Figure 2a and Figure 2b As shown, the support frame 11 is provided with a through hole 111 (i.e. an opening). The liquid above the support frame 11 can flow into the lower part of the support frame 11 through the through hole 111, that is, the liquid refrigerant above the support frame 11 can pass through the through hole 111 and enter the containing space 4.

[0048] Continuing to refer to Figure 2a and Figure 2b , and Figure 3a In a preferred embodiment, the projection of the mounting base 12 on the cross section of the liquid reservoir 2 is located within the projection of the through hole 111 on the cross section of the liquid reservoir 2. It should be understood that the cross section of the liquid reservoir 2 is a cross section perpendicular to the axis of the liquid reservoir 2 itself. In this way, after the mounting base 12 is fixed with the support frame 11, it can only cover part of the area of the through hole 111. The liquid refrigerant above the support frame 11 can enter the containing space 4 through the area of the through hole 111 which is not covered by the mounting base 12, and flow out of the liquid reservoir 2 from the liquid outlet 21 under the action of the spoiler 13.

[0049] In an example, the shapes of the support frame 11 and the mounting base 12 are both circular, the center of the through hole 111 coincides with the center of the support frame 11, and the outer diameter of the mounting base 12 is smaller than the inner diameter of the through hole 111.

[0050] In another preferred embodiment, the through hole 111 can be arranged at any position on the support frame 11, that is, the center of the through hole 111 of the support frame 11 can also not coincide with the center of the support frame 11.

[0051] Preferably, the support frame 11 and / or the mounting base 12 are provided with a connecting part 112, which is used to fix the support frame 11 and the mounting base 12.

[0052] Reference Figure 2a and Figure 3a As shown, in one specific embodiment, the connecting part 112 is fixed to the inner wall of the through hole 111 of the support frame 11 and protrudes toward the interior of the through hole 111.

[0053] Preferably, the mounting base 12 can be bolted to the support frame 11. For example, the connecting part 112 can be provided with a first fixing hole 113, and the mounting base 12 can be provided with a second fixing hole 121. Bolts can be inserted into the first fixing hole 113 and the second fixing hole 121 in sequence to realize the connection between the mounting base 12 and the support frame 11.

[0054] In another specific embodiment, the connecting part 112 can also be fixed to the outer wall of the mounting base 12 and protrude outward. In this case, the connecting part 112 can be provided with a second fixing hole 121 that matches the first fixing hole 113 on the support frame 11.

[0055] In another specific embodiment, there are two connecting parts 112. One connecting part 112 is disposed on the inner wall of the through hole 111 of the support frame 11 and protrudes inward, while the other connecting part 112 is disposed on the outer wall of the mounting base 12 and protrudes outward. In this case, fixing holes can be opened at the relative positions of the two connecting parts 112 to achieve a fixed connection between the support frame 11 and the mounting base 12.

[0056] Reference Figure 2a and Figure 3a As shown, in a specific example, there are two first fixing holes 113, which are arranged opposite each other on the support frame 11; there are also two second fixing holes 121, which are arranged opposite each other on the mounting base 12. In order to facilitate the installation of the support frame 11 and the mounting base 12, the distance D1 between the centers of the two first fixing holes 113 is equal to the distance D2 between the centers of the two second fixing holes 121, that is, D1 = D2.

[0057] In an optional example, during actual installation, the axis of the mounting base 12 can be aligned with the axis of the support frame 11, and the mounting base 12 can be placed against the lower surface of the support frame 11. Then, after aligning the first fixing hole 113 with the second fixing hole 121, the bolts are passed through the two fixing holes in sequence and tightened with nuts to complete the installation of the support frame 11 and the mounting base 12.

[0058] Of course, the mounting seat 12 can be fixed at any position on the support frame 11 when the mounting seat 12 and the support frame 11 are installed, and the axis of the mounting seat 12 can not coincide with the axis of the support frame 11 after the mounting seat 12 is fixed. It can be understood that the through hole 111 of the mounting seat 12 and the support frame 11 can also be irregularly shaped.

[0059] The application does not limit the connection mode of the support frame 11 and the mounting seat 12, and the support frame 11 and the mounting seat 12 can also be fixed by clamping, bonding, welding or other suitable modes.

[0060] Referring to Figures 3a to 3c , and combining Figure 6a , in an example, the spoiler 13 is fixed perpendicularly and detachably on the bottom surface of the mounting seat 12, that is, the spoiler 13 is perpendicular to the bottom surface of the mounting seat 12. The number of the spoiler 13 is at least two, and all the spoilers 13 are arranged at an angle and intersect with each other so as to prevent vortex of the liquid refrigerant below the mounting seat 12.

[0061] Preferably, all the spoilers 13 are arranged along the radial direction of the mounting seat 12, which can effectively prevent vortex of the liquid refrigerant in the circumferential direction of the mounting seat 12.

[0062] Optionally, all the spoilers 13 can also be arranged on the mounting seat 12 as required, that is, the spoiler 13 can be arranged at any position below the mounting seat 12.

[0063] Referring to Figures 4a to 4c , and combining Figure 3a , in a specific example, the mounting seat 12 is provided with a first recess 122 penetrating through the bottom horizontal surface. The first recess 122 is composed of a head end portion 1221 and a tail end portion 1222, one side of the tail end portion 1222 is communicated with the head end portion 1221, and the other side is communicated with the outside. The head end portion 1221 covers and is larger than the tail end portion 1222 at both ends of the recess of the mounting seat 12, and the slot width W3 of the head end portion 1221 in the radial direction of the mounting seat 12 covers and is larger than the slot width W4 of the tail end portion 1222 in the radial direction of the mounting seat 12, that is, W3> W4, at this time, the first recess 122 is a stepped groove.

[0064] Preferably, one side of the spoiler 13 is provided with a head end mounting portion 1311 matched with the shape of the first recess 122, and the head end mounting portion 1311 is used for inserting and limiting in the first recess 122, so as to make the spoiler 13 and the mounting seat 12 slide connection. In this way, after the spoiler 13 is inserted into the first recess 122, it can be positioned below the mounting seat 12, at this time, the spoiler 13 can only move along the slotting direction of the first recess 122 relative to the mounting seat 12, and cannot move in other directions.

[0065] Further, the first groove 122 can be arranged in a radial direction or a non-radial direction of the mounting base 12, and can be arranged at any position on the mounting base 12 as required, as long as the mounting base 12 can meet the structural strength requirement after the first groove 122 is arranged.

[0066] Preferably, the first groove 122 is arranged in a radial direction of the mounting base 12, so that if the liquid refrigerant forms a vortex, the spoiler 13 can be perpendicular to the flow direction of the liquid refrigerant, thereby better preventing the liquid refrigerant from forming a vortex.

[0067] The shape of the first groove 122 is not limited in the present application. In the present embodiment, the shape of the first groove 122 is T-shaped (positive T-shaped). In other embodiments, the shape of the first groove 122 can also be cross-shaped or rivet-shaped or other shapes, as long as the shape of the first groove 122 can meet the requirement that the first spoiler 131 can be movably connected with the mounting base 12 after the first spoiler 131 is inserted.

[0068] In a preferred example, the vortex prevention device 1 further comprises a positioning block 14 (refer to Figure 6a , Figure 6b and Figure 7a , Figure 7b ), and the number of the positioning block 14 is at least two. Specifically, each spoiler 13 needs to be equipped with two positioning blocks 14. After the spoiler 13 is inserted into the first groove 122, the positioning block 14 is used to be inserted into the first groove 122 at one end of the spoiler 13 and is in interference fit with the first groove 122, so that the positioning block 14 is fixed in the mounting base 12 and cannot move relative to the mounting base 12. In this way, when the left and right ends of the spoiler 13 are inserted into the positioning blocks 14, the spoiler 13 and the positioning blocks 14 can jointly limit the movement of the spoiler 13 relative to the mounting base 12, so as to limit the spoiler 13 in the first groove 122 of the mounting base 12.

[0069] Refer to Figures 4a to 4c , Figures 5a to 5c , and combine with Figure 6a and Figure 6b , as a preferred embodiment, the number of the spoiler 13 is two, specifically, the spoiler 13 comprises a first spoiler 131 and a second spoiler 132, and the top of the first spoiler 131 is provided with a first mounting slot 133 penetrating in the width direction of the first spoiler 131, and the second spoiler 132 is used to be inserted into the first mounting slot 133, so as to connect the first spoiler 131 and the second spoiler 132 with each other.

[0070] In a preferred example, the bottom of the second spoiler 132 is provided with a second mounting slot 134 (refer to Figure 5a ) penetrating in the width direction of the second spoiler 132, and the slot width of the second mounting slot 134 matches the slot width of the first mounting slot 133, and the second mounting slot 134 is used to be clamped and limited with the first mounting slot 133.

[0071] It should be appreciated that the first mounting slot 133 and the second mounting slot 134 are engaged and limited to each other, that is, the first spoiler 131 is inserted and limited in the second mounting slot 134, and the second spoiler 132 is inserted and limited in the first mounting slot 133, so that the first spoiler 131 and the second spoiler 132 are fixedly connected.

[0072] With reference to Figure 3a , Figure 4a and Figure 5a , as a preferred embodiment, the first spoiler 131 and the second spoiler 132 are both axisymmetric structures, and the length L1 of the first spoiler 131 and the length L2 of the second spoiler 132 are both matched with the outer diameter D3 of the mounting seat 12, at this time, the length L1 of the first spoiler 131 and the length L2 of the second spoiler 132 are both slightly smaller than the outer diameter D3 of the mounting seat 12, that is, L1 < D3 and L2 < D3. In this way, after the first spoiler 131 and the second spoiler 132 are installed, the symmetry axis of the first spoiler 131 and the symmetry axis of the second spoiler 132 are both coincided with the axis of the mounting seat 12, and can cover the entire bottom surface of the mounting seat 12, so as to effectively prevent the liquid refrigerant from forming vortex below the mounting seat 12.

[0073] Preferably, the first mounting slot 133 is symmetrically arranged about the symmetry axis of the first spoiler 131, and the second mounting slot 134 is symmetrically arranged about the symmetry axis of the second spoiler 132, at this time, after the first spoiler 131 and the second spoiler 132 are fixedly connected through the first mounting slot 133 and the second mounting slot 134, the first spoiler 131 and the second spoiler 132 are crossed and perpendicular to each other, and the first spoiler 131 is symmetrically arranged on both sides of the second spoiler 132, and the second spoiler 132 is symmetrically arranged on both sides of the first spoiler 131, so that the first spoiler 131 and the second spoiler 132 can be evenly distributed on the entire circumference of the mounting seat 12.

[0074] As a first mounting mode, the second mounting slot 134 of the second spoiler 132 is inserted into the position of the first mounting slot 133 of the first spoiler 131, at this time, the second spoiler 132 is inserted into the first mounting slot 133, and the first spoiler 131 is inserted into the second mounting slot 134, so as to realize the fixed connection of the first spoiler 131 and the second spoiler 132 through the mutual engagement of the second mounting slot 134 and the first mounting slot 133.

[0075] As the second installation mode, the head end mounting portion 1311 of the first spoiler 131 is inserted into the first recess 122 of the mounting seat 12 first, and then the second spoiler 132 is inserted into the first mounting slot 133 of the first spoiler 131 and moved relative to the first spoiler 131. When the second spoiler 132 is moved to the position where the second mounting slot 134 corresponds to the first mounting slot 133 in the first mounting slot 133, the second spoiler 132 can be moved downward so that the second mounting slot 134 and the first mounting slot 133 are clamped and limited to each other.

[0076] Referring to Figure 3a As shown, the mounting seat 12 is preferably provided with a second recess 123 penetrating along the radial direction of the mounting seat 12 at the bottom, and the first recess 122 and the second recess 123 form a predetermined included angle. The first recess 122 and the second recess 123 are preferably perpendicular to each other at the bottom of the mounting seat 12. The second recess 123 can be communicated with the first mounting slot 133 after the first spoiler 131 is inserted into the first recess 122, and the through slot formed by the communication of the second recess 123 and the first mounting slot 133 is used to place the second spoiler 132.

[0077] It should be noted that the predetermined included angle between the first recess 122 and the second recess 123 on the mounting seat 12 should match the included angle formed by the first spoiler 131 and the second spoiler 132 after installation.

[0078] In more detail, in the second installation mode, after the first spoiler 131 is inserted into the first recess 122 and moved to the position where the first mounting slot 133 corresponds to the second recess 123, the second spoiler 132 can be inserted into the through slot formed by the second recess 123 and the first mounting slot 133 until the position of the second mounting slot 134 corresponds to the position of the first mounting slot 133.

[0079] Referring to Figures 4a to 4c 、 Figures 5a to 5b In a preferred embodiment, the first spoiler 131 further includes a main body structure 1312 connected to the head end mounting portion 1311, wherein the head end mounting portion 1311 covers and is larger than the main body structure 1312 at both ends, and the width W1 of the head end mounting portion 1311 is greater than the width W2 of the main body structure 1312, i.e. W1>W2.

[0080] To facilitate the smooth insertion of the first spoiler 131 into the first groove 122, the width W1 of the head end mounting portion 1311 of the first spoiler 131 is less than the width W3 of the head end portion 1221 of the first groove 122, i.e., W1 < W3. The width W2 of the main body structure 1312 of the first spoiler 131 is less than the width W4 of the tail end portion 1222 of the first groove 122, i.e., W2 < W4. The height H1 of the head end mounting portion 1311 of the first spoiler 131 is less than the height H2 of the head end portion 1221 of the first groove 122, i.e., H1 < H2.

[0081] To facilitate the smooth insertion of the second spoiler 132 into the second groove 123, the width W5 of the second spoiler 132 is less than the width W6 of the second groove 123, i.e., W5 < W6. Furthermore, to facilitate the smooth insertion of the second spoiler 132 into the first spoiler 131, the width W5 of the second spoiler 132 is less than the width W8 of the first mounting groove 133 of the first spoiler 131, i.e., W5 < W8.

[0082] To facilitate the smooth installation of the first spoiler 131 and the second spoiler 132, the width W2 of the main structure 1312 of the first spoiler 131 is smaller than the width W7 of the second mounting groove 134 of the second spoiler 132, i.e., W2 < W7. The height H3 of the second spoiler 132 is smaller than the height H4 of the first mounting groove 133 of the first spoiler 132, i.e., H3 < H4.

[0083] It should be noted that in other examples, the second groove 123 may not be provided on the mounting base 12. In this case, the first spoiler 131 and the second spoiler 132 can be snapped together and connected, and the head end mounting part 1311 of the first spoiler 131 can be inserted into the first groove 122 of the mounting base 12 to fix the first spoiler 131 and the second spoiler 132 on the mounting base 12.

[0084] Reference Figure 7a and Figure 7b As shown, in a preferred embodiment, the baffle 13 is provided with a plurality of through holes 15 for the passage of liquid (i.e., liquid refrigerant). The through holes 15 further reduce the circumferential speed of the liquid refrigerant in the receiver 2. Since the kinetic energy generated by the circumferential movement of the liquid refrigerant is consumed, it better avoids the generation of eddies in the liquid refrigerant at the drain port 21 of the receiver 2, so no vortices are generated to enter the refrigerant pump 3. This further improves the flow rate and head of the refrigerant pump 3 and increases the efficiency of the refrigerant pump 3.

[0085] Preferably, the number of through-slot holes 135 is multiple, and all the through-slot holes 135 are arranged on the spoiler 13 at intervals, and the multiple through-slot holes 135 arranged at intervals can all be used for the liquid refrigerant to pass through, so as to further reduce the kinetic energy of the liquid refrigerant, reduce the flow speed of the liquid refrigerant, and further avoid the generation of vortex.

[0086] With reference to the foregoing Figure 7a and Figure 7b In a specific example, the spoiler 13 is symmetrically arranged on both sides of the self-symmetry axis with n through-slot holes 135. The arrangement of the through-slot holes 135 on the spoiler 13 needs to meet the following conditions: the length L3 of the through-slot hole 135 in the extension direction is less than twice a predetermined length, and the predetermined length is the length L1 of the first spoiler 131 minus the width W8 of the first mounting groove 133 and then minus 10 mm, that is, 2L3 < L1-W8-10. The interval H5 between the adjacent two through-slot holes 135 is less than or equal to the height H6 of each through-slot hole 135, that is, H5 ≤ H6. The n times of the sum of the height H6 of each through-slot hole 135 and the interval H5 between the adjacent two through-slot holes 135 is set as a second predetermined value, and the difference between the height H7 of the first spoiler 131 and the height H1 of the head end mounting portion 1311 of the first spoiler 131 is set as a third predetermined value, and the second predetermined value is less than or equal to the third predetermined value, that is, n(H6+H5) ≤ H7-H1.

[0087] The application does not limit the arrangement direction of the through-slot hole 135 on the spoiler 13. In an example, the extension direction of the through-slot hole 135 is perpendicular to the extension direction of the symmetry axis of the spoiler 13, so that the liquid refrigerant is more easily passed through the through-slot hole 135 in the flow process.

[0088] In other examples, the extension direction of the through-slot hole 135 can also be parallel to the extension direction of the symmetry axis of the spoiler 13, or the extension direction of the through-slot hole 135 forms a certain angle with the extension direction of the symmetry axis of the spoiler 13. The application does not limit the arrangement direction of the through-slot hole 135 on the spoiler 13.

[0089] The application also does not limit the shape of the through-slot hole 135 on the spoiler 13.

[0090] In summary, the application provides a vortex prevention device and a liquid storage device. The vortex prevention device 1 is installed in the liquid storage device 2 close to the liquid outlet 21. The vortex prevention device 1 has a spoiler 13, and the spoiler 13 is fixed in the liquid storage device 2 through a support frame 11 and a mounting seat 12. After the liquid refrigerant enters the containing space 4 below the support frame 11, the circumferential movement speed of the liquid refrigerant in the liquid storage device 2 can be reduced due to the blocking of the spoiler 13, so that the liquid refrigerant flowing from the liquid storage device 2 into the refrigerant pump 3 housing generates less or even no vortex, thereby improving the flow and lift of the refrigerant pump 3, improving the working efficiency of the refrigerant pump 3, and improving the service life and performance of the refrigerant pump 3.

Any modification or modification made by a person skilled in the art according to the above disclosure is within the protection scope of the present application.
