Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drainers, specifically relating to a zero-gas-consumption automatic drainer. Background Technology
[0002] In modern industrial production systems, compressed air, with its advantages of being clean, efficient, easy to transport and control, has become an indispensable power source and is widely used in various production processes in many industries such as machinery manufacturing, electronics, chemicals, and food processing.
[0003] Currently, during the compressed air supply process in factories, water vapor carried in the compressed air condenses and accumulates at several key locations due to temperature and pressure variations. Specifically, the air compressor, as the initial equipment for generating compressed air, becomes a primary area for water vapor condensation at its bottom due to temperature fluctuations during operation and the pressure difference created by air compression. Large amounts of water vapor condense and gradually settle and accumulate here. The air storage tank, as the core container for storing compressed air, also provides suitable conditions for water vapor condensation due to its relatively stable internal environment, leading to a continuous accumulation of moisture at the bottom. Furthermore, the lowest point of the compressed air pipeline, influenced by gravity, also becomes a convergence point for water vapor, where a continuous stream of water vapor condenses and accumulates. Moreover, if this accumulated moisture cannot be discharged in a timely and effective manner, it will have a severely adverse impact on the quality of the compressed air and the entire production process.
[0004] To address the issue of water carryover in compressed air, the market commonly employs the installation of automatic compressed air drain valves. However, existing automatic compressed air drain valves have the following drawbacks in practical applications: during the drainage process, they often inevitably cause gas loss, which not only wastes energy but also significantly increases production costs for enterprises. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing automatic compressed air drainage structures used in compressed air supply lines are prone to causing gas loss. This invention proposes and designs a zero-gas-consumption automatic drainer, which overcomes the defects of existing automatic compressed air drain valves and achieves zero-gas-consumption drainage function efficiently and stably, thereby effectively solving the problem of gas waste.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a zero-gas-consumption automatic drainer, comprising a drain tank body, an inlet at the upper part of the drain tank body, a drain outlet at the lower part of the drain tank body, and a drain control mechanism inside the drain tank body; an outer cooperating pipe is provided at the outer side of the drain outlet, and an inner cooperating pipe is provided at the inner side of the drain outlet, with a hinge seat above the end of the inner cooperating pipe away from the outer cooperating pipe; the drain control mechanism includes a lever, the middle part of which is hinged to the hinge seat, and a control spring connected between one end of the lever and the inner cooperating pipe; a float is provided at the other end of the lever, and a water-stop baffle is provided on the lower side of the lever, with the water-stop baffle and the float located on the same side of the hinge seat; when the water level inside the drain tank body is higher than that of the inner cooperating pipe, the water-stop baffle can fit against the end face of the inner cooperating pipe; when the water-stop baffle fits against the end face of the inner cooperating pipe, the control spring is in a stretched state. At this time, when this utility model is installed at the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, and the bottom of the compressed air pipeline, the condensate at the bottom of the air compressor exhaust pipe, the bottom of the air tank, and the bottom of the compressed air pipeline can enter the main body of the drain tank of this utility model through the reserved interface and the water inlet. Moreover, under the combined action of the elastic force of the control spring, the weight of the lever, the weight of the water-stop baffle, the weight of the float, and the buoyancy borne by the float, it is ensured that the water-stop baffle and the end face of the inner fitting pipe can only be separated when the water level inside the main body of the drain tank is significantly higher than the highest point of the inner fitting pipe. It is also ensured that when the drain outlet is sealed by the water-stop baffle, the water level inside the main body of the drain tank is slightly higher than the highest point of the inner fitting pipe, thereby ensuring that only water is discharged from the drain outlet and no compressed air is leaked out, achieving zero air consumption drainage.
[0007] Furthermore, the center of gravity of the lever and the water-stop baffle are located on the same side of the hinge seat, so as to fully ensure that the lever can control the water-stop baffle to fit against the end face of the inner mating pipe when the water level is low.
[0008] Furthermore, the water-stop baffle is perpendicular to the lever to further reduce the lever's rotation range and prevent the water level from being too low when the inner fitting pipe is closed.
[0009] Furthermore, the main body of the drainage tank is equipped with a one-button drainage button, which can be manually operated to achieve rapid drainage in emergency or maintenance situations.
[0010] Furthermore, the one-button drainage button includes an operating hole on the outer wall of the drainage tank body. A control lever is vertically slidably mounted inside the operating hole. The upper end of the control lever extends out of the drainage tank body, and the lower end of the control lever extends out of the operating hole and is fitted with a retaining bracket. The lower end of the retaining bracket can contact the end of the lever on which a control spring is located. A return spring is provided between the upper end of the retaining bracket and the inner wall of the drainage tank body. At this time, if it is necessary to operate the one-button drainage button to achieve rapid drainage, simply press the control lever down, so that the retaining bracket at the lower end of the control lever presses against the lever, thereby controlling the lever to rotate counterclockwise to open the inner fitting tube and achieve rapid drainage. Moreover, after the rapid drainage action is completed, under the action of the return spring, the control lever can be moved upward to ensure that the lever can rotate clockwise and continue to close the inner fitting tube.
[0011] Furthermore, a heating device is provided on the outside of the main body of the drainage tank, and the heating device can be detachably installed on the outside of the main body of the drainage tank using fasteners such as clips, so that workers can remove it when it is not winter; and the arrangement of the heating device is preferably a ring arrangement.
[0012] Furthermore, a drain outlet is provided at the lower part of the main body of the drainage tank, and an end cap can be detachably installed at the drain outlet to seal it.
[0013] Furthermore, a pressure relief port is provided at the upper part of the drain tank body, and a pressure relief device is installed at the pressure relief port. The air inside the drain tank body can be discharged by operating the pressure relief device, so as to ensure that the condensate at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline can flow smoothly into the drain tank body from the inlet after the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline is connected to this utility model. Moreover, the pressure relief device can be directly constructed by threading a copper knob at the pressure relief port, and the pressure relief port can be opened or closed by turning the copper knob.
[0014] Furthermore, the inner or outer wall of the water inlet is provided with a threaded section, which can be connected to the corresponding water pipe or fitting in the compressed air supply pipeline through the threaded section, so as to connect to the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, the bottom of the compressed air pipeline, etc. Moreover, valves, dirt removers, etc. can be added to the connected pipeline for easy use and maintenance.
[0015] Furthermore, the inner or outer wall of the outer fitting pipe of the drain outlet is provided with a threaded section, which can be connected to the corresponding water pipe or fitting in the compressed air supply line through the threaded section to connect to the corresponding water receiving component.
[0016] As can be seen from the above technical solutions, this utility model has the following advantages:
[0017] 1. When this utility model is installed at the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline, this utility model can ensure that the end face of the water-stop baffle and the inner fitting pipe can only be separated when the water level inside the main body of the drain tank is significantly higher than the highest point of the inner fitting pipe, under the combined action of the control spring force, the weight of the lever, the weight of the water-stop baffle, the weight of the float, and the buoyancy borne by the float; and ensure that when the drain outlet is sealed by the water-stop baffle, the water level inside the main body of the drain tank needs to be slightly higher than the highest point of the inner fitting pipe, so as to ensure that only water is discharged from the drain outlet and no compressed air is leaked out, achieving zero air consumption drainage;
[0018] 2. This utility model enables rapid drainage by manually operating the one-button drainage function in emergency or maintenance situations. During the drainage process, a large water flow flushes the drain outlet, thereby cleaning it to a certain extent.
[0019] 3. This utility model has a heating device installed on the outside of the main body of the drainage tank, which can heat the main body of the drainage tank in cold seasons to prevent it from freezing; it can be removed in non-winter seasons.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0026] like Figure 1 As shown, this utility model provides a zero-air-consumption automatic drainer, which includes a drain tank body 1, preferably made of aluminum alloy. The upper part of the drain tank body 1 is provided with a water inlet 5 and a pressure relief port 3. The inner or outer wall of the water inlet 5 is provided with a threaded section, which can be connected to a corresponding water pipe or fitting in the compressed air supply pipeline to a reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline. Furthermore, valves and dirt removers can be added to the connected pipeline for easy use and maintenance. A pressure relief device 2 is installed at the pressure relief port 3. During initial use or in abnormal situations, the air inside the drain tank body 1 can be discharged by operating the pressure relief device 2, ensuring that condensate from the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline can flow smoothly from the water inlet 5 into the drain tank body 1 after the device is connected to the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline. Furthermore, the pressure relief device 2 can directly adopt a structure in which a copper knob is threadedly connected to the pressure relief port 3, and the pressure relief port 3 can be opened or closed by turning the copper knob.
[0027] The lower ends of the drainage tank body 1 are respectively provided with a drain outlet 8 and a drain outlet 13. The drain outlet 8 is used to discharge impurities from inside the drainage tank body 1 and to facilitate regular cleaning of the interior of the drainage tank body 1 by operators to prevent blockages. An end cap 7 is detachably installed at the drain outlet 8 to seal it. The drain outlet 13 has an external mating pipe section 12 located on the outer side of the drainage tank body 1. The inner or outer wall of the external mating pipe section 12 of the drain outlet 13 is provided with a threaded section, which can be connected to a corresponding water pipe or fitting in the compressed air supply line to connect to the corresponding water receiving component. The drain outlet 13 is provided with an inner mating pipe 11 on the inner side of the drain tank body 1. A hinge seat 16 is provided above the end of the inner mating pipe 11 away from the outer mating pipe 12. The hinge seat 16 can be directly fixed to the inner mating pipe 11, or fixed to the inner wall of the drain tank body 1 by means of a connecting rod or other structure. A drainage control mechanism is installed at the hinge seat 16.
[0028] Specifically, the drainage control mechanism includes a lever 15, the middle of which is hinged to a hinge seat 16, and a control spring 14 is connected between the end of the lever 15 near the drain outlet 13 and the inner fitting tube 11; a float ball 6 is provided at the end of the lever 15 away from the drain outlet 13, and a water-stop baffle 10 is provided on the lower side of the lever 15, so that the center of gravity of the water-stop baffle 10, the float ball 6, and the lever 15 are located on the same side of the hinge seat 16. Meanwhile, this utility model can also control the center of gravity position of lever 15, as well as the elastic force of spring 14 and the weight of float 6, so that when the water level inside the main body 1 of the drainage tank is significantly higher than the highest point of the inner fitting pipe 11, the lever 15 can rotate counterclockwise under the combined action of the elastic force of spring 14, the weight of lever 15, the weight of water-stop baffle 10, the weight of float 6, and the buoyancy borne by float 6, so as to separate the water-stop baffle 10 from the end face of the inner fitting pipe 11 and realize timely drainage; and when the water level inside the main body 1 of the drainage tank is slightly higher than the highest point of the inner fitting pipe 11, the lever 15 can rotate clockwise under the combined action of the elastic force of spring 14, the weight of lever 15, the weight of water-stop baffle 10, the weight of float 6, and the buoyancy borne by float 6, so as to fit the water-stop baffle 10 with the end face of the inner fitting pipe 11 and realize timely closure of the drain outlet 13. Since the water level inside the main body 1 of the drainage tank is always higher than the top of the drain outlet 13 throughout the entire process, only water is discharged from the drain outlet 13, and no compressed air leaks out, thus achieving zero-air-consumption drainage. In addition, as a preferred embodiment, the water-stop baffle 10 can be perpendicular to the lever 15 to further reduce the rotation range of the lever 15 and prevent the water level from being too low when the inner fitting pipe 11 is closed.
[0029] In addition, this utility model also provides a one-button drainage button at the upper end of the drainage tank body 1, which can be manually operated to achieve rapid drainage in emergency or maintenance situations. Specifically, the one-button drainage button includes an operating hole 19 on the outer wall of the drainage tank body 1. An operating lever 20 is vertically slidably installed in the operating hole 19. The upper end of the operating lever 20 extends out of the drainage tank body 1, and the lower end of the operating lever 20 extends out of the operating hole 19 and is fitted with an abutment bracket 18. The lower end of the abutment bracket 18 can contact one end of the lever 15 on which a control spring 14 is provided. A return spring 17 is provided between the upper end of the abutment bracket 18 and the inner wall of the drainage tank body 1, and the two ends of the return spring 17 are fixedly connected to the abutment bracket 18 and the upper wall of the drainage tank body 1, respectively. At this time, if it is necessary to operate the one-button drainage to achieve rapid drainage, simply press down on the operating lever 20, so that the abutment bracket 18 at the lower end of the operating lever 20 presses against the lever 15, thereby controlling the lever 15 to rotate counterclockwise to open the inner fitting tube 11 and achieve rapid drainage. Moreover, after the rapid drainage action is completed, under the action of the return spring 17, the operating lever 20 can be controlled to move upward to ensure that the lever 15 can rotate clockwise and continue to close the inner fitting tube 11. Furthermore, as a preferred embodiment, this utility model can, on the one hand, design the shape of the abutment bracket 18 as L-shaped, and connect the horizontal section of the abutment bracket 18 to the lower end of the operating lever 20. The upper end of the vertical section of the abutment bracket 18 can abut against the top of the drainage tank body 1 after the horizontal section of the abutment bracket 18 separates from the lever 15, thereby preventing the operating lever 20 from detaching from the drainage tank body 1. On the other hand, a nut with a size larger than the operating hole 19 can be threaded to the upper end of the operating lever 20, and the nut can prevent the operating lever 20 from falling into the drainage tank body 1.
[0030] Meanwhile, this utility model can also provide multiple heating devices 4 on the outside of the drainage tank body 1, and the heating devices 4 can be detachably installed on the outside of the drainage tank body 1 using fasteners such as clips; moreover, the arrangement of the heating devices 4 is preferably a ring-wound arrangement, and the female end of a 12V power adapter 9 can be connected to the male end of the heating device 4, and the male end of the power adapter 9 can be plugged into a 220V socket. Furthermore, if the ambient temperature is above 0 degrees Celsius, installation is not required; if the installation environment is indoors, the heating devices 4 do not need to be repeatedly disassembled, avoiding unnecessary labor.
[0031] Based on this, when this utility model is installed at the reserved interface at the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline, and is used for condensate collection and discharge, it is necessary to first unscrew the pressure relief device 2 on the top of the drain tank body 1 during initial use to ensure that the air in the drain tank body 1 can flow out naturally with the condensate from the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline flowing in from the water inlet 5. After water flows out from the drain outlet 13 of the drain tank body 1, the pressure relief device 2 should be closed in time.
[0032] Next, condensate from the bottom of the air compressor exhaust pipe, the bottom of the air tank, or the bottom of the compressed air pipeline flows into the cavity of the drain tank body 1 through the inlet 5 and accumulates inside. When the water volume accumulates to the point that the buoyancy of the stainless steel float 6 is greater than the weight of the float 6 itself, the force exerted by the lever 15 on the float 6, and the air pressure inside the drain tank body 1, the float 6 will rise and, through the lever 15, lift the water-stop baffle 10, causing the water in the cavity to be discharged through the drain outlet 13. When the water level in the cavity decreases, the float 6 falls, and the water-stop baffle 10 returns to its original position under the combined action of the lever 15 and the control spring 14, stopping the drainage from the drain outlet 13. Throughout this process, the water level in the cavity remains higher than the top of the drain outlet 13, so only water is discharged from the drain outlet 13, with no compressed air leakage, achieving zero-air-consumption drainage.
[0033] Meanwhile, in case of maintenance or other emergencies, the one-button drain can be pressed, which will lift the water-stop baffle 10 for rapid drainage. Simultaneously, the one-button drain process will also use a large water flow to scrape away mud, sand, and other foreign objects adhering between the drain outlet 13 and the water-stop baffle 10, facilitating the cleaning of the drain outlet 13 and preventing blockages or leaks caused by foreign objects. For cleaning and maintenance, manual cleaning can be performed by opening the drain port 8 at the bottom of the drain tank body 1 to remove mud, rust, and other debris from the cavity of the drain tank body 1.
[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
