Its function is to ensure that the ammonia pump is fully supplied with low-pressure ammonia liquid. It also plays the role of an ammonia liquid separator, so that the gaseous refrigerant flows into the suction chamber of the compressor. The compressor water ring vacuum pump currently has centralized pipeline water supply and pipeline return water. Since the system uses circulating water, the water quality is poor, and after a long time, the inlet and outlet pipes are prone to blockage, making maintenance difficult, and the centralized water supply consumes a lot of energy, which can easily cause large-scale shutdown of the compressor system.

[0003] In the prior art, the patent document with publication number CN108644118A proposes a water ring vacuum pump system with a circulating water tank, including a circulating water tank, a water ring vacuum pump and a press, a return water pipe and a water supply pipe are respectively arranged between the circulating water tank and the water ring vacuum pump, the return water pipe is higher than the water supply pipe, a forming mold is arranged in the press, and a water suction pipe is arranged between the forming mold and the water ring vacuum pump. The present invention is easy to maintain, reduces the use of centralized water pumps, and ensures the normal use of the press.

[0004] The existing technology has the following problems: the water quality of the water brush in the cleaning section is very important. The process requires manual drainage twice per shift. Due to manual drainage, there are large fluctuations in the drainage cycle and drainage volume, which have a certain impact on the cleaning quality. In particular, when draining, the operator is very likely to forget to close the drain valve, and the circulating tank is emptied, resulting in serious poor cleaning problems. Summary of the invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the manual drainage in the prior art, which has large fluctuations in drainage cycle and drainage volume, and has a certain impact on the cleaning quality. In particular, when draining, the operator is very likely to forget to close the drain valve, and the circulating tank is emptied, resulting in serious poor cleaning problems.

[0006] In order to solve the above technical problems, the present invention provides an automatic fixed-discharge circulating water tank, comprising:

[0007] A lap base movably sleeved on the outer surface of the bottom of the water circulation tank;

[0008] A water pipe ball valve fixedly connected to the outer surface of the top of the water circulation tank;

[0009] A water supply pipe fixedly connected to the outer surface of one end of the water pipe ball valve;

[0010] A waste valve fixedly connected to the bottom edge of the right side of the water pipe ball valve;

[0011] A quantitative drainage unit is fixedly connected to the right inner bottom wall of the water circulation tank, and the quantitative drainage unit includes a positioning drainage pipe, a sliding pipe, a floating head, a hard rubber strip and a seepage hole. A closed floating unit is fixedly connected to one end of the hard rubber strip, and the closed floating unit includes a closed sleeve and a counterweight block.

[0012] In one embodiment of the present invention, a downward pressure anti-floating unit is provided on the inner surface of the positioning drain pipe, and the downward pressure anti-floating unit includes a trumpet head, an L-shaped clamping arm, a lap top plate, a small motor, a swing rod and a swing extrusion plate.

[0013] In one embodiment of the present invention, the seepage hole is positioned at the bottom edge of the positioning drain pipe, a support frame is fixedly connected to the inner wall of the positioning drain pipe, the outer surface of the support frame is fixedly connected to the inner wall of the positioning drain pipe, and there are multiple support frames, the trumpet head is positioned at the top surface of the positioning drain pipe, and the outer surface of the sliding tube is movably sleeved on the inner wall of the support frame.

[0014] In one embodiment of the present invention, the top end of the sliding tube is fixedly connected to the bottom surface of the floating head. When the floating head floats up, it will drive the sliding tube to pull it. When the sliding tube moves upward, it cooperates with the support frame to limit the position of the sliding tube. When the sliding tube moves upward again, it will pull the hard rubber strip, and the bottom surface of the floating head is movably overlapped on the top outer surface of the bugle head. The water source slowly rises inside the water circulation tank. When the water source spreads over the bugle head and contacts the floating head, the buoyancy generated by the water source on the floating head is used to float it upward. A limiting block is fixedly connected to the outer surface of the floating head.

[0015] In one embodiment of the present invention, the top end of the hard rubber strip is fixedly connected to the bottom surface of the sliding tube, the other end of the hard rubber strip is fixedly connected to the top surface of the closed sleeve, and the inner wall of the closed sleeve is fixedly connected to a limiting strip. As the water source is continuously discharged, the buoyancy of the floating head will gradually decrease and thus descend. After the water source drops to 1.6 meters, the buoyancy of the floating head will be completely eliminated, and the sliding tube will be used to squeeze and descend the hard rubber strip, and the closed sleeve will be completely fitted to the inner bottom edge of the positioning drain pipe again to block the water hole of the seepage hole. The outer surface of the counterweight block is arranged on the inner wall of the closed sleeve, and the outer surface of the closed sleeve is movably overlapped on the inner bottom wall of the positioning drain pipe.

[0016] In one embodiment of the present invention, the bottom end of the L-shaped clamping arm is fixedly connected to the top outer surface of the horn head, the outer surface of the limit block is movably overlapped on the outer surface of the L-shaped clamping arm, and the bottom surface of the overlapping top plate is fixedly connected to the top surface of the L-shaped clamping arm, thereby reducing the water source inside the water circulation tank. When the floating head floats up and down, the position of the floating head is limited by the limit block and the L-shaped clamping arm, so that it moves vertically up and down, and the outer surface of the swing rod is movably sleeved on the top outer surface of the overlapping top plate.

[0017] In one embodiment of the present invention, the outer surface of the small motor is fixedly mounted on the top surface of the overlapping top plate, and the output end of the small motor is fixedly connected to the two ends of the swing rod, and the water supply pipe ball valve is adjusted to adjust the water supply flow rate, and the water supply is controlled to be automatically discharged once every 30 minutes to reduce the number of poor cleaning times. After two discharges a day, the small motor is controlled in conjunction with the electromagnetic liquid level meter, and the swing rod is rotated in conjunction with the small motor. The outer surface of the swinging extrusion plate is fixedly connected to the outer surface of the swing rod, so that the swinging extrusion plate on the outer surface of the swing rod is vertically erected downward, and one end of the swinging extrusion plate is overlapped on the top surface of the floating head. After the subsequent water pipe ball valve infuses water into the water circulation tank, the water source spreads through the floating head, and the floating head will not float up, thereby causing the internal water source to be continuously discharged, and one end of the swinging extrusion plate is movably overlapped on the top outer surface of the floating head.

[0018] In one embodiment of the present invention, an electromagnetic level gauge is provided on the left edge of the front side of the water circulation tank, a closed top cover is movably overlapped on the top surface of the water circulation tank, a water guide chute is provided on the inner wall of the bottom of the water circulation tank, a water guide groove is provided inside the lower right corner of the water circulation tank, and the bottom end of the positioning drain pipe is fixedly connected to the top surface of the water guide chute. When the water source inside the water circulation tank rises to 1.7 meters, the water pipe ball valve is closed, and the buoyancy of the floating head will pull up one end of the closed sleeve from the inner bottom wall of the positioning drain pipe. At this time, the external water source will enter the interior of the positioning drain pipe through the seepage hole, and the water source entering the interior of the positioning drain pipe will pass through the water guide groove and then be discharged through the waste valve. The water source is used to fill the interior of the water circulation tank with water in conjunction with the water pipe ball valve, and the water source inside is diverted and accumulated to one side in conjunction with the water guide chute.

[0019] In one embodiment of the present invention, a deformable soft block is fixedly connected to the top surface of the overlapping base, a C-shaped docking strip is fixedly connected to the top surface of the deformable soft block, and the inner surface of the C-shaped docking strip is movably overlapped on the outer surface of the corner of the water circulation tank.

[0020] In one embodiment of the present invention, a snap-fit ​​lock buckle is fixedly connected to the top surface of the C-shaped docking strip, and the inner surface of the snap-fit ​​lock buckle is movably overlapped on the top surface of the closed top cover.

[0021] The above technical solution of the present invention has the following advantages compared with the prior art:

[0022] The automatic fixed-discharge circulating water tank described in the present invention cooperates with a water pipe ball valve to infuse water into the water circulating tank, and cooperates with a water guiding chute to divert and accumulate the internal water to one side, and the water source slowly rises inside the water circulating tank. When the water source spreads over the horn head and contacts with the floating head, the buoyancy generated by the water source on the floating head is used to float the floating head upward. When the floating head floats up, it drives the sliding pipe to pull it, and when the sliding pipe moves upward, it cooperates with the support frame to limit the position of the sliding pipe, and when the sliding pipe moves upward again, it pulls the hard rubber strip. When the water source inside the water circulating tank rises to 1.7 meters, the water pipe ball valve is closed, and the buoyancy of the floating head will pull one end of the closed sleeve from the inner bottom wall of the positioning drain pipe. At this time, the external water source will enter the interior of the positioning drain pipe through the seepage hole, and the water source entering the interior of the positioning drain pipe will pass through the water guiding groove and then be discharged through the waste valve.

[0023] The automatic fixed-discharge circulating water tank described in the present invention will gradually reduce the buoyancy of the floating head as the water source is continuously discharged and the water source drops, thereby dropping. After the water source drops to 1.6 meters, the buoyancy of the floating head will be completely eliminated, and the sliding pipe will be used to squeeze the hard rubber strip and drop it, and the closed sleeve will be fully fitted to the inner bottom edge of the positioning drain pipe again to block the water hole of the seepage hole, thereby reducing the water source inside the water circulation tank. When the floating head floats up and down, the limit block and the L-shaped clamping arm are used to limit the position of the floating head so that it can move vertically up and down.

[0024] The automatic fixed-discharge circulating water tank described in the present invention adjusts the water replenishment flow rate by adjusting the water replenishment pipe ball valve, and controls the automatic fixed-discharge to be performed once every 30 minutes, thereby reducing the number of poor cleaning times. After two discharges a day, the small motor is controlled in conjunction with the electromagnetic liquid level meter, and the swing rod is rotated in conjunction with the small motor, so that the swing extrusion disk on the outer surface of the swing rod is vertically erected downward, and one end of the swing extrusion disk is overlapped on the top surface of the floating head. After the subsequent water pipe ball valve infuses water source into the water circulation tank, the floating head will not float up after the water source spreads through the floating head, thereby causing the internal water source to be continuously discharged.

[0043] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0045] A lap base 12 movably sleeved on the outer surface of the bottom of the water circulation tank 11;

[0046] A water pipe ball valve 13 fixedly connected to the outer surface of the top of the water circulation tank 11;

[0047] A water supply pipe 14 fixedly connected to the outer surface of one end of the water pipe ball valve 13;

[0048] A waste valve 15 fixedly connected to the bottom edge of the right side of the water pipe ball valve 13;

[0049] A quantitative drainage unit is fixedly connected to the right inner bottom wall of the water circulation tank 11, and the quantitative drainage unit includes a positioning drainage pipe 115, a sliding pipe a3, a floating head a4, a hard rubber strip a5 and a seepage hole a6. A closed floating unit is fixedly connected to one end of the hard rubber strip a5, and the closed floating unit includes a closed sleeve a51 and a counterweight block a52.

[0050] When the quantitative drainage unit provided by the present invention is in use, the water source is infused into the water circulation tank 11 in cooperation with the water pipe ball valve 13, and the internal water source is diverted and accumulated to one side in cooperation with the water guide chute 113. When the water source slowly rises inside the water circulation tank 11, when the water source contacts the surface of the floating head a4, the buoyancy generated by the water source on the floating head a4 is used to float it upward. When the floating head a4 floats, it will drive the slide pipe a3 to pull it, and when the slide pipe a3 moves upward, the hard rubber strip a5 will be pulled when the slide pipe a3 moves upward again. When the water source inside the water circulation tank 11 rises to 1.7 meters, the water pipe ball valve 13 is closed, and the buoyancy of the floating head a4 will pull one end of the closed sleeve a51 from the inner bottom wall of the positioning drain pipe 115. At this time, the external water source will enter the interior of the positioning drain pipe 115 through the seepage hole a6, and then be discharged through the waste valve 15.

[0051] Furthermore, if Figure 7 - Fig. 9 As shown, a downward pressure anti-floating unit is arranged on the inner surface of the positioning drain pipe 115, and the downward pressure anti-floating unit includes a trumpet head a2, an L-shaped clamping arm a21, an overlapping top plate a22, a small motor a23, a swing rod a24 and a swing squeezing plate a25.

[0052] When in use, the horn head a2, L-shaped clamping arm a21, overlapping top plate a22, small motor a23, swing rod a24 and swing extrusion plate a25 provided by the present invention cooperate with the electromagnetic liquid level meter 111 to control the small motor a23, and cooperate with the small motor a23 to rotate the swing rod a24, so that the swing extrusion plate a25 on the outer surface of the swing rod a24 is vertically erected downward, and one end of the swing extrusion plate a25 is overlapped on the top surface of the floating head a4. After the water pipe ball valve 13 subsequently infuses water source into the water circulation tank 11, the water source spreads through the floating head a4, and the floating head a4 will not float up, thereby causing the internal water source to be continuously discharged.

[0053] Furthermore, if Figure 7 - Fig. 9 As shown, the position of the seepage hole a6 is set at the bottom edge of the positioning drain pipe 115, and the inner wall of the positioning drain pipe 115 is fixedly connected to the support frame a1, the outer surface of the support frame a1 is fixedly connected to the inner wall of the positioning drain pipe 115, and the number of support frames a1 is set in plurality, the position of the trumpet head a2 is set on the top surface of the positioning drain pipe 115, and the outer surface of the sliding pipe a3 is movably sleeved on the inner wall of the support frame a1.

[0054] When the support frame a1, the bugle head a2 and the slide tube a3 provided by the present invention are in use, the bugle head a2 cooperates to limit the position of the bottom surface of the floating head a4, and the floating head a4 floats up under the drive of the water source, and cooperates with the slide tube a3 to slide on the inner wall surface of the support frame a1, and the support frame a1 is used to limit the position of the slide tube a3.

[0056] When the floating head a4 and the limit block a41 provided by the present invention are in use, when the floating head a4 floats up from the inside of the horn head a2, the limit block a41 on the outer surface of the floating head a4 is used to limit its position by the L-shaped clamping arm a21 when it rises, so as to avoid position deviation of the floating head a4 when it rises.

[0057] Furthermore, if Figure 6As shown, the top end of the hard rubber strip a5 is fixedly connected to the bottom surface of the sliding tube a3, the other end of the hard rubber strip a5 is fixedly connected to the top surface of the closed sleeve a51, the inner wall of the closed sleeve a51 is fixedly connected to the limiting strip a53, the outer surface of the counterweight block a52 is arranged on the inner wall of the closed sleeve a51, and the outer surface of the closed sleeve a51 is movably overlapped on the inner bottom wall of the positioning drain pipe 115.

[0058] When the closed sleeve a51 and the positioning drain pipe 115 provided by the present invention are in use, the buoyancy of the floating head a4 will pull one end of the closed sleeve a51 up from the inner bottom wall of the positioning drain pipe 115, so that the blockage of the inner wall of the seepage hole a6 is removed, thereby allowing the external water source to enter the interior of the positioning drain pipe 115 and discharge the water source.

[0059] Furthermore, if Figure 6 - Fig. 9 As shown, the bottom end of the L-shaped clamping arm a21 is fixedly connected to the top outer surface of the horn head a2, the outer surface of the limit block a41 is movably overlapped on the outer surface of the L-shaped clamping arm a21, the bottom surface of the overlapping top plate a22 is fixedly connected to the top surface of the L-shaped clamping arm a21, the outer surface of the swing rod a24 is movably sleeved on the top outer surface of the overlapping top plate a22, the outer surface of the small motor a23 is fixedly installed on the top surface of the overlapping top plate a22, and the output end of the small motor a23 is fixedly connected to the two ends of the swing rod a24, the outer surface of the swing extrusion disk a25 is fixedly connected to the outer surface of the swing rod a24, and one end of the swing extrusion disk a25 is movably overlapped on the top outer surface of the floating head a4.

[0060] When the L-shaped clamping arm a21, overlapping top plate a22 and swing rod a24 provided by the present invention are in use, after two discharges a day, the small motor a23 is controlled in conjunction with the electromagnetic liquid level meter 111, and the swing rod a24 is rotated in conjunction with the small motor a23, so that the swing extrusion plate a25 on the outer surface of the swing rod a24 is vertically erected downward.

[0061] Furthermore, if Figure 1 - Figure 3 As shown, an electromagnetic liquid level gauge 111 is arranged on the left edge of the front side of the water circulation tank 11, a closed top cover 112 is movably overlapped on the top surface of the water circulation tank 11, a water guide chute 113 is arranged on the bottom inner wall of the water circulation tank 11, a water guide groove 114 is arranged inside the lower right corner of the water circulation tank 11, and the bottom end of the positioning drain pipe 115 is fixedly connected to the top surface of the water guide chute 113.

[0062] When in use, the electromagnetic liquid level meter 111, the closed top cover 112, the water guiding chute 113 and the water guiding groove 114 provided by the present invention cooperate with the electromagnetic liquid level meter 111 to check the water level inside the water circulation tank 11, and at the same time cooperate with the water guiding chute 113 to guide the water source to one side so that the water source accumulates together, and then the accumulated water source is collected and discharged through the water guiding groove 114.

[0063] Furthermore, if Figure 2 As shown, a deformable soft block 121 is fixedly connected to the top surface of the overlapping base 12, a C-shaped docking strip 122 is fixedly connected to the top surface of the deformable soft block 121, and the inner surface of the C-shaped docking strip 122 is movably overlapped on the outer surface of the corner of the water circulation tank 11, a snap-on lock 123 is fixedly connected to the top surface of the C-shaped docking strip 122, and the inner surface of the snap-on lock 123 is movably overlapped on the top surface of the closed top cover 112.

[0064] When the deformable soft block 121, C-shaped docking strip 122 and snap-on lock buckle 123 provided by the present invention are in use, when the closed top cover 112 is sleeved on the top surface of the water circulation tank 11, the C-shaped docking strip 122 is swung in cooperation with the deformable soft block 121 to be sleeved on the corner position of the water circulation tank 11, and at the same time, the snap-on lock buckle 123 on the top end of the C-shaped docking strip 122 is snapped on the top surface of the closed top cover 112 to limit its position.

[0065] The working principle of the auxiliary loading and unloading device is described in detail below.

[0066] Cooperate with the water pipe ball valve 13 to inject water into the water circulation tank 11, cooperate with the water guide chute 113 to divert the internal water to one side for accumulation, when the water source slowly rises inside the water circulation tank 11, when the water source spreads over the horn head a2, when the water source contacts the floating head a4, the buoyancy generated by the water source on the floating head a4 is used to float it upward, when the floating head a4 floats, it will drive the slide pipe a3 to pull it, and when the slide pipe a3 moves upward, cooperate with the support frame a1 to slide the slide pipe a3 The position is limited, and when the sliding pipe a3 moves up again, it will pull the hard rubber strip a5. When the water source inside the water circulation tank 11 rises to 1.7 meters, the water pipe ball valve 13 is closed, and the buoyancy of the floating head a4 will pull up one end of the closed sleeve a51 from the inner bottom wall of the positioning drain pipe 115. At this time, the external water source will enter the interior of the positioning drain pipe 115 through the seepage hole a6. The water source entering the interior of the positioning drain pipe 115 will pass through the water guide groove 114 and then be discharged through the waste valve 15.

[0067] As the water source is continuously discharged, the buoyancy of the floating head a4 will gradually decrease and it will drop as the water source drops. When the water source drops to 1.6 meters, the buoyancy of the floating head a4 will be completely eliminated, and the sliding tube a3 will be used to squeeze and lower the hard rubber strip a5, and the closed sleeve a51 will be fully fitted to the inner bottom edge of the positioning drain pipe 115 again to block the water hole a6 and reduce the water source inside the water circulation tank 11. When the floating head a4 floats up and down, the limit block a41 and the L-shaped clamping arm a21 are used to limit the position of the floating head a4 so that it can move vertically up and down.

[0068] Adjust the water supply pipe ball valve to adjust the water supply flow rate, control it to automatically discharge once every 30 minutes, and reduce the number of poor cleaning times. After two discharges a day, cooperate with the electromagnetic liquid level meter 111 to control the small motor a23, and cooperate with the small motor a23 to rotate the swing rod a24, so that the swing squeeze disk a25 on the outer surface of the swing rod a24 is vertically erected downward, and one end of the swing squeeze disk a25 is overlapped on the top surface of the floating head a4. After the subsequent water pipe ball valve 13 infuses water into the water circulation tank 11, the water source spreads through the floating head a4, and the floating head a4 will not float up, resulting in the continuous discharge of the internal water source.

[0069] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
