Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors and their related equipment, and particularly relates to an air compression system with automatic drainage. Background Technique

[0002] An air compressor is the main body in the air source device. It is a device that converts the mechanical energy of an electric motor into gas pressure energy and is a pneumatic pressure generating device for compressed air. As an important form of energy generation, air compressors are widely used in various links of life and production. In particular, twin-screw air compressors are widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textile industry, etc.

[0003] During the use of an air compressor, it needs to cooperate with components such as pipelines, gas storage tanks, oil-water separators, and filters to form an air compression system. During the use of the existing air compression system, generally, a solenoid valve is required to drain the water in the air compression system. For example, the automatic drainage device for an air compressor with the patent publication number CN216896792U discloses an automatic drainage device for a mine air compressor.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. Most of the existing air compression systems with automatic drainage use solenoid valves for drainage operations. Currently, most solenoid valves are installed using threaded connections or the cooperation of flange plates and fixing bolts during installation. These methods are cumbersome and time-consuming when staff disassemble, install, and replace solenoid valves, resulting in low work efficiency.

[0006] 2. Most of the existing air compression systems with automatic drainage use solenoid valves to achieve automatic drainage operations. Due to the lack of drainage monitoring and valve body fault monitoring measures, in the case of poor drainage or valve body failure, it will affect the drainage efficiency, safety, and reliability of the air compression system. Therefore, we provide an air compression system with automatic drainage to solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide an air compression system with automatic drainage. By setting a docking component, it is convenient for staff to quickly disassemble, install, and replace the intelligent automatic drainage valve body, which saves time and effort and has high work efficiency. And by using the liquid level sensor in the intelligent automatic drainage valve body, the water level of the condensate in the air compression system can be monitored in real time, realizing efficient, intelligent, and automated drainage functions. And by using two groups of flow sensors and a fault display alarm to judge whether there is poor drainage or a fault in the intelligent automatic drainage valve body and give an alarm, thereby improving the operation efficiency, safety, and reliability of the air compression system.

[0008] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0009] The utility model relates to an air compressor system with automatic drainage, which comprises an air compressor body and a gas storage tank, a separator, a dryer and a filter which are arranged in sequence along the horizontal direction on one side of the air compressor body. The air compressor body, the gas storage tank, the separator, the dryer and the filter are connected by a main pipe adjacent to each other. Inner drain pipes are arranged at the bottoms of the air compressor body, the gas storage tank, the separator, the dryer and the filter. The outer ends of the inner drain pipes are butt-jointed and installed with an outer drain pipe through an intelligent automatic drain valve body. Flange plates are arranged on the opposite end faces of the inner drain pipe and the outer drain pipe. Docking components are sleeved on the outer sides of both ends of the intelligent automatic drain valve body;

[0010] The docking component comprises a fixing ring and a convex ring fixedly connected to the middle of the outer wall thereof. A sliding ring is slidably connected to the outer side of the outer wall of the convex ring.

[0011] The utility model is further arranged that a fault display alarm is arranged on one side of the outer wall of the intelligent automatic drain valve body, and sealing rings are bonded to both ends of the intelligent automatic drain valve body.

[0012] The utility model is further arranged that a liquid level sensor is arranged at the inner bottom end of the middle part of the water channel of the intelligent automatic drain valve body, and flow sensors are arranged at the water outlet ends and the water inlet ends on both sides of the water channel of the intelligent automatic drain valve body.

[0013] The utility model is further arranged that the output end of the fault display alarm is electrically connected to the input end of an intelligent controller, and the output end of the intelligent controller is electrically connected to the input ends of the two flow sensors and the liquid level sensor.

[0014] The utility model is further arranged that telescopic rods are uniformly and spacedly installed along the circumferential direction on the inner wall of the sliding ring. Springs are sleeved on the outer sides of the outer walls of the telescopic rods, and the other ends of the telescopic rods are installed on the outer wall of the fixing ring.

[0015] The utility model is further arranged that the spring is located between the outer wall of the fixing ring and the inner wall of the sliding ring, and an arc opening is arranged on the outer side of the inner wall of the sliding ring.

[0016] The utility model is further arranged that rotating shafts are uniformly and spacedly installed along the circumferential direction on the outer wall of the convex ring. Torsion springs are sleeved on the central positions of the outer walls of the rotating shafts, and clamping plates are uniformly and spacedly arranged along the circumferential direction on the outer side of the convex ring.

And by using two flow sensors, the flow difference between the water inlet end and the water outlet end during the drainage process can be detected, and then it can be judged whether there is poor drainage or a fault in the intelligent automatic drain valve body. If the above problems occur, the fault is displayed by the fault display alarm and a remote alarm is issued, thus improving the reliability of the operation of the air compressor system. It solves the problem that most of the existing automatic drainage air compressor systems use solenoid valves to realize automatic drainage operations, and due to the lack of drainage monitoring and valve body fault monitoring measures, when there is poor drainage or a fault, it will affect the drainage efficiency, safety and reliability of the air compressor system.

[0021] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 , the present invention is an air compressor system for automatic drainage, including an air compressor body 1 and an air storage tank 101, a separator 102, a dryer 103, and a filter 104 sequentially arranged on one side of it in the horizontal direction. The air compressor body 1, the air storage tank 101, the separator 102, the dryer 103, and the filter 104 are connected by a main pipe 105 adjacent to each other. Inner drain pipes 106 are provided at the bottoms of the air compressor body 1, the air storage tank 101, the separator 102, the dryer 103, and the filter 104. The outer ends of the inner drain pipes 106 are butt - installed with an outer drain pipe 107 through an intelligent automatic drain valve body 2. Flange plates 106a are provided on the opposite end faces of the inner drain pipe 106 and the outer drain pipe 107.

[0035] Specifically, a fault display alarm 201 is provided on one side of the outer wall of the intelligent automatic drain valve body 2, sealing rings 202 are bonded to both ends of the intelligent automatic drain valve body 2, a liquid level sensor 203 is provided at the bottom end of the inner side of the middle part of the water channel of the intelligent automatic drain valve body 2, and flow sensors 204 are provided at the water outlet and water inlet on both sides of the water channel of the intelligent automatic drain valve body 2. The output end of the fault display alarm 201 is electrically connected to the input end of the intelligent controller 205, and the output end of the intelligent controller 205 is electrically connected to the input ends of the two flow sensors 204 and the liquid level sensor 203.

[0036] Furthermore, the air compressor body 1, the air storage tank 101, the separator 102, the dryer 103 and the filter 104 are all existing technologies, so they will not be described in detail here. The water outlet port of the intelligent automatic drain valve body 2 is relatively large, and a grille is arranged inside, which is insensitive to impurities and ensures the high efficiency of drainage. The sealing ring 202 can increase the sealing of the pipe connection. The structure and working principle of the liquid level sensor 203 and the flow sensor 204 are all existing technologies, so they will not be described in detail here. Among them, the liquid level sensor 203 can reliably sense various condensates and discharge them in time. The fault display alarm 201 can display the fault and issue a remote alarm when the drainage is not smooth or a fault occurs, so as to improve the reliability of operation. The two sets of flow sensors 204 respectively monitor the water flow at the water inlet and outlet ends of the intelligent automatic drain valve body 2 to determine whether there is a problem of poor drainage or a fault.

[0037] The operation process of this embodiment is as follows: the air compression system includes an air compressor body 1, an air storage tank 101, a separator 102, a dryer 103, a filter 104 and a main pipe 105, etc. During the use of the air compression system, condensed water will be generated in the above-mentioned multiple components and pipelines. At this time, the water level of the condensed water in the air compression system can be monitored in real time through the liquid level sensor 203 in the intelligent automatic drainage valve body 2. When the water level reaches the preset threshold, the sensing device will send a signal to the external intelligent controller 205, and the intelligent automatic drainage valve body 2 will be driven by the intelligent controller 205 to perform drainage. At the same time, flow sensors 204 are provided at the water inlet and outlet on both sides of the intelligent automatic drainage valve body 2. The two sets of flow sensors 204 can be used to detect the flow difference between the water inlet and the water outlet during the drainage process, and then it can be determined whether the intelligent automatic drainage valve body 2 has poor drainage or a fault. If the above problem occurs, the fault display alarm 201 will display the fault and issue a remote alarm, thereby improving the reliability of the operation of the air compression system.

[0038] Example 2

[0039] See also Figure 3 , Figure 5 andFigure 6 , on the basis of Embodiment 1, different from the first embodiment: a docking component 3 is provided. The docking component 3 includes a fixing ring 301 and a convex ring 302 fixedly connected to the middle of its outer wall. A sliding ring 305 is slidably connected to the outer side of the outer wall of the convex ring 302, which solves the problem that most of the existing automatic drainage air compressor systems use solenoid valves for drainage operations, and now most of the solenoid valves are installed by means of threaded connection or the cooperation of a flange and a fixing bolt during installation. These methods are cumbersome and time-consuming when the staff disassembles, installs, and replaces the solenoid valve, resulting in low work efficiency.

[0040] Specifically, telescopic rods 303 are evenly spaced along the circumferential direction on the inner wall of the sliding ring 305. A spring 304 is sleeved on the outer side of the outer wall of the telescopic rod 303. The other end of the telescopic rod 303 is installed on the outer wall of the fixing ring 301. The spring 304 is located between the outer wall of the fixing ring 301 and the inner wall of the sliding ring 305. An arc opening 305a is provided on the outer side of the inner wall of the sliding ring 305. Rotating shafts 306 are evenly spaced along the circumferential direction on the outer wall of the convex ring 302. A torsion spring 307 is sleeved at the central position of the outer wall of the rotating shaft 306. Clamping plates 308 are evenly spaced along the circumferential direction on the outer side of the convex ring 302. Both the front and rear ends of the inner wall of the clamping plate 308 are fixedly connected with side plates 308a, and the inner wall of the side plate 308a is fixed to the end of the rotating shaft 306.

[0041] Furthermore, the sliding ring 305 can slide along the outer wall of the convex ring 302 under force. The inner wall of the fixing ring 301 is fixed to the outer walls of the inlet and outlet ports of the intelligent automatic drainage valve body 2. The telescopic rod 303 plays a role in limiting the spring 304. Under the elastic performance of the spring 304, it can drive the sliding ring 305 to move. Through the arc opening 305a provided on the outer side of the inner wall of the sliding ring 305, it is convenient for the sliding ring 305 to apply force to the clamping plates 308 around the outer side when it rebounds. There are four groups of clamping plates 308, and the cross-section is L-shaped, mainly used to clamp the inner flange 106a. The clamping plate 308 will rotate around the rotating shaft 306 when it is stressed, and the torsion spring 307 can drive the clamping plate 308 to rotate under its elastic performance.

[0042] The operation process of this embodiment is as follows: when the intelligent automatic drain valve body 2 is damaged and needs to be repaired or replaced, first push the sliding ring 305 on one side inward. Since the inner wall of the sliding ring 305 is slidably connected to the outer wall of the convex ring 302, the sliding ring 305 will move along the outer wall of the convex ring 302 toward the intelligent automatic drain valve body 2 under the force, and will squeeze the telescopic rod 303 and the spring 304. After the sliding ring 305 completely moves to the outside of the outer wall of the convex ring 302, the limiting effect of the sliding ring 305 on the surrounding clamping plates 308 on the outside disappears. At this time, under the elastic performance of the torsion spring 307, the corresponding clamping plate 308 can be driven to rotate outward around the rotating shaft 306, so that the four clamping plates 308 rotate outward to open, and the limiting effect of the clamping plate 308 on the flange 106a on the outer drain pipe 107 can be cancelled. Then, the outer drain pipe 107 can be removed. By repeating the above operation, the inner drain pipe 106 can be removed from the connection of the intelligent automatic drain valve body 2 to complete the disassembly. During installation, similarly, the flange 106a on the outer drain pipe 107 or the inner drain pipe 106 is closely docked with the sealing ring 202 at the end of the intelligent automatic drain valve body 2, and then the force on the sliding ring 305 is stopped. At this time, under the elastic performance of the spring 304, the sliding ring 305 can be ejected along the outer wall of the convex ring 302. Among them, during the ejection process of the sliding ring 305, under the action of the arc opening 305a, the surrounding clamping plates 308 can be smoothly and continuously pushed to rotate and close around the rotating shaft 306 until the four clamping plates 308 are stuck outside the adjacent flange 106a (during this process, the torsion spring 307 is compressed by force), so as to complete the installation of the inner drain pipe 106 or the outer drain pipe 107, thereby facilitating the staff to quickly disassemble, install and replace the intelligent automatic drain valve body 2, saving time and effort and having high work efficiency.
