Description

Technical Field

[0001] This application relates to the field of condensate recovery and utilization technology for temperature control equipment, and more specifically, to a device for condensate recovery and utilization for refrigeration equipment. Background Technology

[0002] In industrial production, the stability of temperature and humidity in the workshop environment, the normal operating status of production equipment, and the operational comfort of workers are key factors in ensuring factory production efficiency and product quality. To achieve these goals, factories typically install multiple high-power industrial air conditioning systems. During the cooling process, water vapor in the air condenses on the surface of the evaporator, forming a large amount of condensate. Directly discharging this condensate not only results in a serious waste of water resources but also increases the risk of slippery workshop floors and falls. Recycling and using this condensate for replenishing cooling equipment (such as industrial cooling towers and equipment cooling loops) effectively reduces the factory's fresh water consumption, aligning with the industrial development needs of energy conservation, emission reduction, cost reduction, and efficiency improvement. Therefore, it has become an important direction for water resource recycling in the industrial sector.

[0003] Currently, there are some simple technical solutions for the recycling of air conditioning condensate in factories. The core structure of such solutions usually includes: a water storage chamber (used to temporarily store condensate) connected to the air conditioning condensate outlet through a pipe, a water pump for transporting the condensate in the water storage chamber to the cooling equipment, and a water supply pipe connecting the water pump outlet to the cooling equipment water inlet.

[0004] However, existing solutions rely on staff to periodically inspect the water level in the storage chamber. When the water level reaches a certain height, the water pump is manually activated to drain the water, and when the water level is too low, the pump is manually shut off. This method not only consumes a lot of labor costs, but also makes it difficult to accurately control the inspection interval. If inspections are not timely, the water level in the storage chamber may become too high, causing condensate to overflow, resulting in water waste and ground safety hazards. Utility Model Content

[0005] The purpose of this application is to provide a condensate recovery and utilization device for refrigeration equipment, which can automatically start drainage.

[0006] To achieve the above objectives, this application provides a condensate recovery and utilization device for refrigeration equipment, comprising: A housing, wherein the housing has a cavity inside; A partition is fixedly disposed in the housing to divide the chamber of the housing into a water storage chamber and an installation chamber; A drainage assembly, wherein the drainage assembly is disposed in the mounting cavity and communicates with the water storage cavity; A water level monitoring component is installed on the partition to acquire water level information in the water storage chamber and send the acquired water level information to the drainage component. When the water level is greater than or equal to a preset height, the drainage component is activated to discharge water from the water storage chamber into the housing.

[0007] In an optional embodiment, the water level monitoring component includes a contact sensor, a first support plate, a lifting column, and a float. The first support plate is fixedly disposed on the partition plate near the side wall of the water storage chamber. An installation through hole is formed on the first support plate along a first direction. The lifting column is slidably installed in the installation through hole of the first support plate. The lifting column is fixedly connected to the float. The contact sensor is disposed on the lifting path of the lifting column. When the float comes into contact with the water, it rises with the water level, and at the same time, it also drives the lifting column to rise. During the rising process, the lifting column abuts against the contact sensor. The contact sensor sends the detected signal to the drainage component, and the drainage component is activated.

[0008] In an optional embodiment, the water level monitoring component further includes a contact plate, which is fixedly mounted on the lifting column at one end near the contact sensor. The lifting column moves up and down, causing the contact plate to move up and down and to abut against the contact sensor.

[0009] In an optional embodiment, the water level monitoring assembly further includes a support block, a second support plate, a sliding rod, an elastic element, a limiting rod, and a pull plate. The support block is fixedly disposed on the partition plate near the side wall of the mounting cavity. A sliding through hole is formed on the support block along a first direction. The sliding rod is slidably installed in the sliding through hole of the support block. The second support plate is fixedly installed on one end of the sliding rod. The contact sensor is fixedly disposed on the second support plate. The sliding rod slides on the support block to drive the second support plate and the contact sensor to move, thereby adjusting the position of the contact sensor. The pull plate is perpendicularly fixed to the limiting rod. A stepped hole is formed on the support block along a second direction. The elastic element and the limiting rod are installed in the stepped hole of the support block. A limiting hole is formed on the sliding rod along the second direction. The number of limiting holes is multiple and they are equidistantly distributed along the first direction. The elastic element drives the pull plate to move towards the sliding rod so that the limiting rod is inserted into one of the limiting holes.

[0010] In an optional embodiment, the water level monitoring component further includes a baffle plate, which is fixedly installed on the other end of the sliding rod. The baffle plate is located in the mounting cavity, and the second support plate is located outside the mounting cavity. In the direction perpendicular to the first direction, the cross-sectional area of ​​the baffle plate is larger than the cross-sectional area of ​​the sliding through hole.

[0011] In an optional embodiment, the water level monitoring component includes an ultrasonic sensor, which is fixedly installed on the partition or the inner wall of the housing, for acquiring the liquid level height of the water storage chamber and sending it to the drainage component.

[0012] In an optional embodiment, a filter screen is also included, which is fixedly disposed in the water storage cavity of the housing and separates a filter chamber from the water storage cavity, and the drainage assembly draws water from the filter chamber.

[0013] In an optional embodiment, the device further includes mounting plates. A set of mounting plates is fixedly disposed on the partition, and another set of mounting plates is fixedly disposed on the inner wall of the housing. Two mounting plates are disposed at intervals in each set, and there is a fixed gap between the two mounting plates. The fixed gap formed by the set of mounting plates on the partition is used to fix one end of the filter screen, and the fixed gap formed by the set of mounting plates on the inner wall of the housing is used to fix the other end of the filter screen.

[0014] In an optional embodiment, the drainage assembly includes a pump pipe, a water pump, and a drain pipe. One end of the pump pipe is connected to the partition plate, the inlet of the pump pipe is located at the filter chamber, the other end of the pump pipe is connected to the pump inlet, and one end of the drain pipe is connected to the pump outlet.

[0015] In an optional embodiment, a water inlet pipe is also included, and a water inlet hole is provided on the housing, with the water inlet pipe passing through the water inlet hole of the housing.

[0016] This application obtains water level information from the storage chamber by setting a water level monitoring component and sends it to the drainage component. When the water level is greater than or equal to the preset height, the drainage component is automatically activated to drain water, eliminating the need for regular manual inspections and manual start / stop of the water pump, thus reducing labor costs and improving the accuracy and timeliness of operation.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Embodiments of this application provide a condensate recovery and utilization device for refrigeration equipment, including a housing 1, a partition 3, a drainage assembly, and a water level monitoring assembly.

[0025] like Figure 1 As shown, the housing 1 has a cavity inside.

[0026] The partition 3 is fixedly installed in the housing 1 to divide the cavity of the housing 1 into a water storage cavity and an installation cavity. The fixing method is, for example, welding, gluing, or integral molding. The water storage cavity is used to store condensate from the refrigeration equipment. The partition 3 provides a mounting base for the drainage components and water level monitoring components, and the installation cavity is used to accommodate the drainage components and water level monitoring components, etc.

[0027] The drainage assembly is installed in the mounting cavity and connected to the water storage cavity. The drainage assembly is used to drain the water in the water storage cavity.

[0028] The water level monitoring component is installed on the partition 3 to obtain the water level information in the water storage chamber and send the obtained water level information to the drainage component. When the water level is greater than or equal to the preset height, the drainage component starts for a preset time to discharge the water in the water storage chamber from the shell 1.

[0029] For example, the preset time can be set according to the actual needs of the project, such as thirty minutes, one hour or two hours.

[0030] Existing simplified technical solutions rely on manual inspection of water levels to start and stop water pump 4, which incurs significant labor costs and makes it difficult to accurately control inspection intervals. Delayed inspections can also lead to water waste and ground safety hazards. This application, however, uses a water level monitoring component to acquire water level information from the storage chamber and send it to the drainage component. When the water level is greater than or equal to a preset height, the drainage component automatically starts draining water, eliminating the need for regular manual inspections and manual start / stop of water pump 4. This reduces labor costs and improves the accuracy and timeliness of operation.

[0031] The water level monitoring component is installed on the partition 3 to obtain the water level information in the water storage chamber and send the obtained water level information to the drainage component. When the water level is greater than or equal to the preset height, the drainage component is activated to discharge the water in the water storage chamber from the shell 1, realizing automatic drainage according to the water level and improving the timeliness and accuracy of drainage.

[0032] By automatically recycling and utilizing air conditioning condensate for replenishing cooling equipment, the factory's fresh water consumption is effectively reduced, meeting the industrial development needs of energy conservation, emission reduction, cost reduction and efficiency improvement, and enhancing the efficiency of water resource utilization.

[0033] like Figures 1 to 3 As shown, in one embodiment, the water level monitoring assembly includes a contact sensor 14, a first support plate 9, a lifting column 10, and a float 11.

[0034] The first support plate 9 is fixedly installed on the side wall of the partition plate 3 near the water storage chamber. The fixing method is, for example, welding, snap-fitting, bolt connection or integral molding.

[0035] The first support plate 9 has a mounting through hole along a first direction. For example, the first direction is a vertical direction. Of course, the first direction can also be set to be slightly inclined to the vertical direction.

[0036] The lifting column 10 is slidably installed in the mounting through hole of the first support plate 9.

[0037] The lifting column 10 is fixedly connected to the float 11, so that the float 11 can drive the lifting column 10 to move. The fixing method is, for example, threaded connection, snap-fit ​​or adhesive.

[0038] The contact sensor 14 is installed on the lifting path of the lifting column 10. When the float 11 comes into contact with the water, it rises with the water level and also drives the lifting column 10 to rise. During the rising process, the lifting column 10 comes into contact with the contact sensor 14. The contact sensor 14 sends the detected signal to the drainage assembly, and the drainage assembly is activated.

[0039] For example, the first support plate 9 has a certain thickness in the first direction, so that the inner wall of the mounting through hole can guide the lifting column 10 to slide along the first direction and accurately touch the contact sensor 14.

[0040] The overall density of the float 11 is less than that of water. The float 11 is made of materials such as foam or plastic so that when the water level rises, the buoyancy of the float 11 can drive the lifting column 10 and the contact plate 12 described below to rise synchronously.

[0041] If the storage chamber does not initially contain water, the length of the lifting column 10 can be extended so that the initial position of the float 11 can abut against the bottom of the housing 1, thereby preventing the lifting column 10 from falling off the first support plate 9.

[0042] To further improve reliability and save materials, such as Figure 3 As shown, in one embodiment, the water level monitoring component further includes a contact plate 12, which is fixedly disposed on the lifting column 10 at one end near the contact sensor 14. The fixing method is, for example, welding, snap-fitting, threaded connection or adhesive bonding.

[0043] The lifting column 10 lifts and lowers, causing the contact plate 12 to lift and lower, and the contact plate 12 abuts against the contact sensor 14.

[0044] The contact plate 12 can increase the contact area with the contact sensor 14, and can also prevent the lifting column 10 from falling off the first support plate 9 when the water level in the water storage chamber drops.

[0045] In order to adjust the position of the contact sensor 14 to adjust the water level threshold when the drainage component starts, thereby adapting to the condensate generation or cooling equipment water replenishment requirements in different industrial scenarios, such as... Figure 2 and Figure 3 As shown, in one embodiment, the water level monitoring assembly further includes a support block 15, a second support plate 13, a sliding rod 16, an elastic element 19, a limiting rod 21, and a pull plate 20.

[0046] The support block 15 is fixedly installed on the partition plate 3 near the side wall of the mounting cavity.

[0047] The support block 15 has a sliding through hole along the first direction, and the sliding rod 16 is slidably installed in the sliding through hole of the support block 15. The sliding rod 16 can slide back and forth along the first direction.

[0048] The second support plate 13 is fixedly installed on one end of the sliding rod 16, and the contact sensor 14 is fixedly installed on the second support plate 13.

[0049] The sliding rod 16 slides on the support block 15 to move the second support plate 13 and the contact sensor 14 to adjust the position of the contact sensor 14.

[0050] The pull plate 20 is vertically fixed to the limiting rod 21. The support block 15 has a stepped hole along the second direction. The elastic element 19 and the limiting rod 21 are installed in the stepped hole of the support block 15. The sliding rod 16 has a limiting hole 18 along the second direction. There are multiple limiting holes 18, which are equidistantly distributed along the first direction. The elastic element 19 drives the pull plate 20 to move towards the sliding rod 16 so that the limiting rod 21 is inserted into one of the limiting holes 18 to lock the sliding rod 16 and keep the contact sensor 14 at a specific height. When it is necessary to adjust the height of the contact sensor 14, the pull plate 20 can be pulled to pull the limiting rod 21 out of the limiting hole 18 so that the sliding rod 16 can slide.

[0051] The specific operating steps are as follows: When it is necessary to raise the starting water level (preset height) of the drainage component, pull the pull plate 20 outward. The pull plate 20 stretches the elastic element 19 and drives the limiting rod 21 to move outward from the stepped hole until the limiting rod 21 is completely disengaged from the limiting hole 18 on the sliding rod 16. Push the sliding rod 16 upward. The sliding rod 16 drives the second support plate 13 and the contact sensor 14 to rise synchronously. When the contact sensor 14 moves to the target height, which is the height corresponding to the required starting water level of the drainage component, stop pushing the sliding rod 16. Release the pull plate 20. Under the action of the elastic restoring force, the elastic element 19 pushes the pull plate 20 to reset. The pull plate 20 drives the limiting rod 21 to pass through the stepped hole and insert into the limiting hole 18 at the corresponding height of the sliding rod 16, thus completing the height fixation of the second support plate 13 and the contact sensor 14.

[0052] If it is necessary to lower the starting water level of the drainage component, repeat the above steps by simply pulling down the sliding rod 16. The baffle 17 at the bottom of the sliding rod 16 can prevent the sliding rod 16 from completely coming out of the sliding hole of the support block 15, ensuring the structural safety of the adjustment process.

[0053] The contact sensor 14 is a conventional position detection sensor. There is a certain distance between the contact plate 12 and the contact sensor 14 in the initial state. This distance corresponds to the preset water level when the drainage component is activated. The contact sensor 14 is electrically connected to the controller (not shown in the figure, the controller can be integrated into the mounting cavity) through a wire. The controller is then electrically connected to the drainage component (the water pump 4 below), forming a control loop of "sensor-controller-drainage component (water pump 4)".

[0054] As the water level in the storage chamber gradually rises with the injection of condensate, the float 11 moves upward under the action of buoyancy, thereby driving the lifting column 10 and the contact plate 12 at the top to float up synchronously. When the contact plate 12 floats up to fully contact the contact sensor 14, the contact sensor 14 sends an electrical signal to the controller, and the controller controls the drainage component to open after receiving the signal.

[0055] like Figure 3 As shown, in one embodiment, the water level monitoring component further includes a baffle 17, which is fixedly installed on the other end of the sliding rod 16. The baffle 17 is located in the mounting cavity, and the second support plate 13 is located outside the mounting cavity. In the direction perpendicular to the first direction, the cross-sectional area of ​​the baffle 17 is larger than the cross-sectional area of ​​the sliding through hole. The baffle 17 can prevent the sliding rod 16 from falling off the support block 15.

[0056] Unlike the technical solution of the water level monitoring component in the above embodiments, in one embodiment, the water level monitoring component includes an ultrasonic sensor. The ultrasonic sensor is fixedly installed on the partition 3 or the inner wall of the housing 1, and is used to obtain the liquid level height of the water storage chamber and send it to the drainage component. If it is necessary to adjust the water level threshold when the drainage component is started, it can be directly input from the ultrasonic sensor side. Of course, the same position adjustment structure as the contact sensor 14 can also be set (e.g., second support plate 13, support block 15, sliding rod 16, baffle 17, pull plate 20 and limit rod 21, etc.).

[0057] like Figure 1 and Figure 4 As shown, in one embodiment, the refrigeration equipment condensate recovery and utilization device further includes a filter screen 8, which is fixedly installed in the water storage cavity of the housing 1 and separates a filter chamber from the water storage cavity. The drainage component draws water from the filter chamber.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment, the refrigeration equipment condensate recovery and utilization device further includes mounting plates 7. A set of mounting plates 7 are fixedly installed on the partition plate 3 and a set of mounting plates 7 are fixedly installed on the inner wall of the housing 1. The fixing method is, for example, welding, snap-fitting or bolt connection.

[0059] Each set is provided with two mounting plates 7, and there is a fixed gap between the two mounting plates 7. The fixed gap formed by the set of mounting plates 7 on the partition plate 3 is used to fix one end of the filter screen 8, and the fixed gap formed by the mounting plates 7 on the inner wall of the housing 1 is used to fix the other end of the filter screen 8.

[0060] For example, the fixed gap is set along the first direction.

[0061] For example, the filter 8 is configured as an L-shaped right-angle plate.

[0062] The two sides of the filter screen 8 can slide along the length direction (first direction) of the fixed gap, which not only achieves stable installation of the filter screen 8, but also facilitates subsequent periodic disassembly and cleaning. The filter screen 8 can intercept solid impurities in the condensate, prevent the subsequent water pump 4 and water pipe 5 from becoming blocked, and ensure the long-term stable operation of the device.

[0063] like Figure 5 As shown, in one embodiment, the drainage assembly includes a pump pipe 5, a water pump 4, and a drain pipe 6. One end of the pump pipe 5 is connected to the partition 3, the inlet of the pump pipe 5 is located at the filter chamber, the other end of the pump pipe 5 is connected to the pump inlet of the water pump 4, and one end of the drain pipe 6 is connected to the pump outlet of the water pump 4.

[0064] For example, the water pump 4 can be electrically connected to a contact sensor, enabling the contact sensor to control the start and stop of the water pump.

[0065] like Figure 1 and Figure 5 As shown, in one embodiment, the condensate recovery and utilization device for refrigeration equipment further includes a water inlet pipe 2, and a water inlet hole is provided on the housing 1, with the water inlet pipe 2 passing through the water inlet hole of the housing 1.

[0066] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
