Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning water circulation system technology, and more specifically, to an energy-saving air conditioning refrigeration water circulation device. Background Technology
[0002] The water circulation system is a crucial component of refrigeration and air conditioning equipment, its function being to circulate cooling water to the equipment to lower its temperature. Over prolonged operation, impurities and scale accumulate in the water pipes, affecting water flow and potentially causing blockages. This can malfunction the system, leading to unnecessary maintenance and wear. To address these impurities and scale, existing air conditioning water circulation systems incorporate filtration devices along the water circulation path. The core components are a filter box and filter plates within it. The filter plates effectively filter impurities and scale from the pipes before re-entering the system with purified water. However, in traditional water circulation systems, with extended operation, trapped impurities and scale accumulate on the filter plate surface and within the filter pores, gradually clogging them and significantly increasing pressure loss during water flow. This not only reduces the overall circulation capacity of the system, affecting cooling performance, but also increases the load on the water pump, resulting in energy waste. When the filter plate is severely clogged, its filtration function is essentially lost, necessitating the shutdown of the water circulation system. The filter plate then needs to be disassembled, cleaned, or replaced. This maintenance process not only affects or even interrupts the operation of the water circulation system but also impacts the normal operation of the entire air conditioning system, affecting the user experience. Furthermore, it can have even more serious consequences in situations requiring continuous cooling. Overall, traditional air conditioning water circulation systems suffer from poor continuous operation and inconvenience in maintenance. Summary of the Invention
[0003] In view of this, this application provides an energy-saving air conditioning cooling water circulation device to solve the technical problems of poor continuous working capacity and poor maintenance convenience of the existing air conditioning water circulation system.
[0004] This application provides an energy-saving air conditioning cooling water circulation device, wherein the energy-saving air conditioning cooling water circulation device includes an outer chamber and an inner chamber rotatably installed in the outer chamber; The inner chamber is divided into two isolated filtration working chambers. A filter plate is provided in the filtration working chamber. The filter plate has multiple filter holes. The filter plate divides the corresponding filtration working chamber into an inlet chamber and an outlet chamber. The bottom of the inlet chamber is closed, and the bottom of the outlet chamber has an opening. The inner chamber has an inlet, which communicates with the inlet chamber and the outside of the inner chamber. The outer chamber has an inlet pipe and an outlet pipe. When the inner chamber rotates, either of the two filter working chambers can be kept in a first position. The inlet chamber of the filter working chamber kept in the first position is connected to the inlet pipe through a corresponding inlet, and the outlet chamber of the filter working chamber kept in the first position is connected to the outlet pipe through a corresponding opening.
[0005] Furthermore, the energy-saving air conditioning cooling water circulation device also includes an elastic resistance mechanism, and each of the filter working chambers is provided with a stop member. The stop member can cooperate with the elastic resistance mechanism to keep the corresponding filter working chamber in the first position. When the water flow thrust on the filter plate in the filter working chamber held in the first position is greater than the elastic force of the elastic resistance mechanism, the stop member overcomes the rotation of the elastic resistance mechanism and causes the inner chamber to rotate until another filter working chamber is held in the first position.
[0006] Furthermore, the stop is a protrusion disposed above the filter plate, and the elastic resistance mechanism includes a sliding block connected to the outer chamber via an elastic telescopic member. When the protrusion abuts against the sliding block and the water flow thrust on the filter plate corresponding to the lower part of the protrusion is less than or equal to the elastic force of the elastic telescopic member, the filter working chamber corresponding to the protrusion abutting against the sliding block remains in the first position. When the protrusion abuts against the sliding block and the water flow thrust on the filter plate corresponding to the lower part of the protrusion is greater than the elastic force of the elastic telescopic member, the protrusion abutting against the sliding block pushes the sliding block to rotate, causing the inner chamber to rotate, until another filter working chamber remains in the first position.
[0007] Furthermore, the inner chamber includes a central rotating column and an inner annular sidewall arranged around the central rotating column. The central rotating column is rotatably connected to the outer chamber via a vertical rotating shaft. Baffles are provided on both sides of the same diameter of the central rotating column. The baffles extend radially along the inner annular sidewall to the inner side of the inner annular sidewall. The central rotating column and the baffles on both sides divide the inner chamber into two filter working chambers. The water inlet is formed on the inner annular sidewall. An inner chamber bottom plate is provided between the bottom of the central rotating column and the bottom of the inner annular sidewall. The inner chamber bottom plate closes the bottom of the water inlet chamber. The outer compartment includes an outer annular sidewall, an outer compartment bottom plate connected to the bottom end of the outer annular sidewall, and an outer compartment cover plate connected to the top end of the outer annular sidewall. The upper end face of the inner annular sidewall is in sealed contact with the lower surface of the outer compartment cover plate. The upper end face of the partition is in sealed contact with the lower surface of the outer compartment cover plate. The lower end face of the inner annular sidewall is in sealed contact with the upper surface of the outer compartment bottom plate. The outer side face of the inner annular sidewall is in sealed contact with the inner side face of the outer annular sidewall. The water inlet pipe is connected to the outside of the outer annular sidewall. The water outlet pipe is connected to the bottom of the outer compartment bottom plate. The upper end of the central rotating column is rotatably connected to the outer compartment cover plate, and the lower end of the central rotating column is rotatably connected to the outer compartment bottom plate.
[0008] Furthermore, the lower surface of the outer compartment cover is provided with an annular groove, and the protrusion extends into the annular groove and can rotate along the annular groove.
[0009] Furthermore, the outer compartment cover has a sliding cavity, the length direction of which is tangent to the annular groove, and the sliding cavity extends through the annular groove along its length direction. The sliding block is slidably installed in the sliding cavity along its length direction. The elastic telescopic member is located in the sliding cavity, one end of which is connected to the bottom end of the sliding cavity, and the other end of which is connected to the sliding block.
[0010] Furthermore, the outer compartment cover includes a cover body and a movable door. An inspection port is formed on the cover body. The movable door is closable and installed at the inspection port. When one of the two filter working chambers is held in the first position, the other filter working chamber is held in the second position. The inspection port leads to the filter working chamber held in the second position.
[0011] Furthermore, a sealing strip is provided above the filter plate, and the protrusion is provided at the upper end of the sealing strip. The upper end surface of the sealing strip is in sealing contact with the lower surface of the outer chamber cover.
[0012] Furthermore, a first slot is provided on the outer periphery of the central rotating column, and a second slot is provided on the inner side of the inner annular sidewall. One end of the filter plate is fitted into the first slot, and the other end of the filter plate is fitted into the second slot. One end of the sealing strip is fitted into the first slot, and the other end of the sealing strip is fitted into the second slot.
[0013] Furthermore, the lower end of the outer warehouse floor is connected to multiple supporting columns.
[0014] The beneficial effects of the energy-saving air conditioning cooling water circulation device provided by this invention are as follows: Compared to existing technologies, the energy-saving air conditioning cooling water circulation device provided by this invention has an inner chamber rotatably installed in the outer chamber, and the inner chamber has two filter working chambers. Therefore, when one of the filter working chambers is in the first position, the filter plate in that filter working chamber can filter the water in the entire water circulation path of the energy-saving air conditioning cooling water circulation system. Once the filter plate accumulates excessive impurities and scale or becomes clogged, the inner chamber can be rotated to the other filter working chamber in the first position, so that the filter plate in the other filter working chamber can perform the filtration operation. At this time, there is no need to stop the energy-saving air conditioning cooling water circulation system. The filter plate that has accumulated excessive impurities and scale or become clogged can be cleaned or replaced simultaneously, which greatly improves the continuous working capacity and maintenance convenience of the air conditioning water circulation system.

[0023] See Figures 1 to 8This application provides an energy-saving air conditioning cooling water circulation device, wherein the energy-saving air conditioning cooling water circulation device includes an outer chamber and an inner chamber rotatably installed in the outer chamber; The inner chamber is divided into two isolated filter working chambers 100. A filter plate 1 is provided in the filter working chamber 100. The filter plate 1 has multiple filter holes. The filter plate 1 divides the corresponding filter working chamber 100 into an inlet chamber 101 and an outlet chamber 102. The bottom of the inlet chamber 101 is closed. The bottom of the outlet chamber 102 has an opening 103. The inner chamber has an inlet 104. The inlet 104 communicates with the inlet chamber 101 and the outside of the inner chamber. The outer chamber has an inlet pipe 2 and an outlet pipe 3. When the inner chamber rotates, either of the two filter working chambers 100 can be kept in the first position. The inlet chamber 101 of the filter working chamber 100 kept in the first position is connected to the inlet pipe 2 through the corresponding inlet port 104. The outlet chamber 102 of the filter working chamber 100 kept in the first position is connected to the outlet pipe 3 through the corresponding opening 103. The inlet pipe 2 and the outlet pipe 3 can be connected to the energy-saving air conditioning cooling water circulation system, so that the entire energy-saving air conditioning cooling water circulation device is part of the water circulation path of the entire energy-saving air conditioning cooling water circulation system. The water in this water circulation path enters the inlet chamber 101 of the filter working chamber 100 in the first position from the inlet pipe 2 and passes through the filter plate 1 in the filter working chamber 100 to obtain water that has been filtered of impurities, scale and other substances. This part of the water then flows back into the water circulation path through the outlet chamber 102 and the outlet pipe 3, thereby ensuring the cleanliness of the water in the water circulation path of the entire energy-saving air conditioning cooling water circulation system.
[0024] Because the energy-saving air conditioning cooling water circulation device provided by the present invention has an inner chamber rotatably installed in an outer chamber, and the inner chamber has two filter working chambers 100, when one of the filter working chambers 100 is in the first position, the filter plate 1 in the filter working chamber 100 can filter the water in the water circulation path of the entire energy-saving air conditioning cooling water circulation system. Once the filter plate 1 has excessive accumulation of impurities and scale or blockage, the inner chamber can be rotated to the other filter working chamber 100 in the first position, so that the filter plate 1 in the other filter working chamber 100 can be used for filtration. At this time, there is no need to stop the energy-saving air conditioning cooling water circulation system, and the filter plate 1 with excessive accumulation of impurities and scale or blockage can be cleaned or replaced simultaneously, which greatly improves the continuous working capacity and maintenance convenience of the air conditioning water circulation system.
[0025] According to a preferred embodiment of this application, the energy-saving air conditioning cooling water circulation device further includes an elastic resistance mechanism. Each filter working chamber 100 is provided with a stop member. The stop member can cooperate with the stop of the elastic resistance mechanism to keep the corresponding filter working chamber 100 in a first position. When the water flow thrust on the filter plate 1 in the filter working chamber 100 kept in the first position is greater than the elastic force of the elastic resistance mechanism, the stop member overcomes the rotation of the elastic resistance mechanism and causes the inner chamber to rotate until the other filter working chamber 100 is kept in the first position. The advantage of this embodiment is that when the filter plate 1 has excessive accumulation of impurities and scale or blockage, the resistance of the filter plate 1 to the passing water flow increases, and the water flow thrust on the filter plate 1 gradually increases. When it increases to a level greater than the elastic force of the elastic resistance mechanism, the other filter working chamber 100 can be kept in the first position to perform filtration work, thereby realizing the automatic switching of the two filter working chambers 100 in the first position.
[0026] According to one embodiment of this application, the stop is a protrusion 4 disposed above the filter plate 1. The elastic resistance mechanism includes a sliding block 6 connected to the outer chamber via an elastic telescopic member 5. When the protrusion 4 abuts against the sliding block 6 and the water flow thrust on the filter plate 1 corresponding to the lower part of the protrusion 4 is less than or equal to the elastic force of the elastic telescopic member 5, the filter working chamber 100 corresponding to the protrusion 4 abutting against the sliding block 6 remains in the first position. When the protrusion 4 abuts against the sliding block 6 and the water flow thrust on the filter plate 1 corresponding to the lower part of the protrusion 4 is greater than the elastic force of the elastic telescopic member 5, the protrusion 4 abutting against the sliding block 6 pushes the sliding block 6 to rotate, causing the inner chamber to rotate until another filter working chamber 100 remains in the first position. When the protrusion 4 abutting against the sliding block 6 pushes the sliding block 6 to rotate, under the continued pushing of the water flow on the filter plate 1 during the initial stage of the inner chamber rotation and under the rotational inertia of the inner chamber, it can... To ensure that the inner chamber remains in the first position as it rotates to another working chamber, the opening 103 at the bottom of the outlet chamber 102 should preferably be large enough. Preferably, the opening 103 at the bottom of the outlet chamber 102 is aligned with the projected area of the outlet chamber 102 along the rotation axis of the inner chamber. This ensures that water still flows from the outlet chamber 102 into the outlet pipe 3 during the longer rotational stroke at the start of the inner chamber's rotation. Moreover, the inlet 104 preferably has a relatively long arc-shaped extension along the circumferential direction of the inner annular sidewall 300. Preferably, the inlet 104 extends from one end of the inlet chamber 101 to the other end along the circumferential direction of the inner annular sidewall 300. For example, when the angle between the inlet chamber 101 and the outlet chamber 102 in the circumferential direction of the inner annular sidewall 300 is 90°, the central angle of the trajectories corresponding to the extension of the inlet 104 is also 90°.

The central rotating column 200 is rotatably connected to the outer chamber via a vertical rotating shaft 201. Partitions 7 are provided on both sides of the same diameter of the central rotating column 200. The partitions 7 extend radially along the inner annular sidewall 300 to the inner side of the inner annular sidewall 300. The central rotating column 200 and the partitions 7 on both sides divide the inner chamber into two filter working chambers 100. An inlet 104 is formed on the inner annular sidewall 300. An inner chamber bottom plate 8 is provided between the bottom of the central rotating column 200 and the bottom of the inner annular sidewall 300. The inner chamber bottom plate 8 closes the bottom of the inlet chamber 101. The outer compartment includes an outer annular sidewall 9, an outer compartment bottom plate 10 connected to the bottom of the outer annular sidewall 9, and an outer compartment cover plate 400 connected to the top of the outer annular sidewall 9. The upper end face of the inner annular sidewall 300 is in sealed contact with the lower surface of the outer compartment cover plate 400. The upper end face of the partition 7 is in sealed contact with the lower surface of the outer compartment cover plate 400.

The water inlet pipe 2 is connected to the outer side of the outer annular sidewall 9. The water outlet pipe 3 is connected to the bottom of the outer compartment bottom plate 10. The upper end of the central rotating column 200 is rotatably connected to the outer compartment cover plate 400. The lower end of the central rotating column 200 is rotatably connected to the outer compartment bottom plate 10.

[0028] According to one embodiment of this application, the lower surface of the outer compartment cover 400 is provided with an annular groove 403, and the protrusion 4 extends into the annular groove 403 and can rotate along the annular groove 403. The protrusion 4 can rotate in the annular groove 403, thereby enabling the inner compartment to continuously switch the filter working chamber 100 at the first position.
[0029] According to one embodiment of this application, the outer compartment cover 400 has a sliding cavity 404, the length direction of the sliding cavity 404 is tangent to the annular groove 403, and the sliding cavity 404 extends through the annular groove 403 along its length direction. The sliding block 6 is slidably installed in the sliding cavity 404 along the length direction of the sliding cavity 404. The elastic telescopic member 5 is located in the sliding cavity 404, one end of the elastic telescopic member 5 is connected to the bottom end of the sliding cavity 404, and the other end of the elastic telescopic member 5 is connected to the sliding block 6.
[0030] According to one embodiment of this application, the outer compartment cover 400 includes a cover body 401 and a movable door 402. An inspection port is formed on the cover body 401, and the movable door 402 is closably installed at the inspection port. When one of the two filter working chambers 100 is held in a first position, the other filter working chamber 100 is held in a second position. The inspection port leads to the filter working chamber 100 held in the second position. This allows for convenient cleaning or maintenance of the filter plate 1 in the filter working chamber 100 in the second position, or replacement, after the movable door 402 is opened. In addition, it is understood that the lower surfaces of the cover body 401 and the movable door 402 together form an annular groove 403, and a sliding cavity 404 is formed on the cover body 401.
