Description

Technical Field

[0001] The invention relates to the technical field of air conditioner heat exchange core production, and in particular to an intelligent air conditioner heat exchange core blockage detection instrument. Background Art

[0002] As the core component of the air conditioning system, the importance of the air conditioning heat exchange core is self-evident. It uses metal plates or other heat exchange media to achieve energy exchange between indoor exhaust air and fresh air, thereby effectively regulating indoor temperature and humidity and providing a comfortable living environment for residents.

[0003] In the production process of air-conditioning heat exchange core, quality inspection is an indispensable link, among which blockage detection and damage detection are two key indicators. The traditional blockage detection method usually involves injecting gas into one end of the air-conditioning heat exchange core and relying on manual observation to see whether gas is discharged from the other end. If no gas is observed to be discharged, it is judged to be blocked. The traditional damage detection method mostly uses the method of blocking both ends and immersing them in a water pool to judge whether there is damage by observing whether bubbles are generated.

[0004] However, these traditional detection methods have exposed many shortcomings in practical applications:

[0005] First of all, the traditional blockage detection can only determine whether the air-conditioning heat exchange core is completely blocked. When the air-conditioning heat exchange core is in a partially blocked state, some gas can still pass through, so this method cannot accurately identify it. This limitation leads to misjudgment of partial blockage conditions, which in turn affects the overall performance of the air-conditioning system.

[0006] Secondly, traditional blockage detection and damage detection require the use of different equipment, which not only increases the detection cost but also reduces the detection efficiency. At the same time, the operation and maintenance of multiple devices also brings additional burdens.

[0007] In addition, traditional detection methods rely heavily on manual operation and subjective judgment, which leads to instability and unreliability of the detection results. Human factors such as improper operation and careless observation may have a negative impact on the detection results.

[0008] Therefore, it is very necessary to invent an intelligent air-conditioning heat exchange core blockage detection instrument. Summary of the invention

[0009] The purpose of the present invention is to provide an intelligent air-conditioning heat exchange core blockage detection instrument to solve the problem that the existing air-conditioning heat exchange core blockage detection device can only detect whether the air-conditioning heat exchange core is completely blocked during use, but cannot detect whether the air-conditioning heat exchange core is partially blocked. Secondly, the detection efficiency is low. In addition, the traditional detection method relies heavily on manual operation and subjective judgment, which leads to instability and unreliability of the detection results.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: it includes a box body, an air storage tank, a fixing frame, an exhaust mechanism, an air intake mechanism, a box door, an air supply pipe, a touch panel and a switch group, wherein the inside of the box body is fixed with an air storage tank through a fixing frame; the output end of the air storage tank is connected with the air supply pipe and the input end of the exhaust mechanism, wherein the exhaust mechanism is fixed inside the box body; the input end of the air storage tank is respectively connected with the air intake mechanism and the air supply pipe, wherein the air intake mechanism is fixed inside the box body; a first solenoid valve is fixed to the middle part of the air supply pipe, and a sealing cover is fixed to the other end of the air supply pipe, wherein an end of the air supply pipe close to the sealing cover is arranged on the outside of the box body; box doors are arranged on the outsides of the output ends of the exhaust mechanism and the air intake mechanism, wherein the box doors are rotatably connected to the box body through hinges; the outer side surfaces of the box body are respectively fixed with a touch panel and a switch group by bolts.

[0012] Furthermore, the exhaust pipe includes a tube body, a reinforcement strip and an anti-bending wire, one end of the tube body is connected to the first Roots flowmeter, and the other end of the tube body is fixed with a first joint; a reinforcement strip is fixed on the outer side of the tube body, wherein an anti-bending wire is fixed inside the reinforcement strip, and the reinforcement strip is made of a rope body woven from steel wire. Such a setting can avoid the influence of the bending of the exhaust pipe on the measurement accuracy.

[0013] Furthermore, the first joint includes a shell, a sealing rubber ring, an inner cavity, a piston and a stud, one end of the shell is connected to the exhaust pipe, wherein a sealing rubber ring is fixed inside the shell; an inner cavity is opened inside the sealing rubber ring, wherein a piston is slidably installed inside the inner cavity; a stud is fixed at one end of the piston, wherein the stud is connected to the shell by threaded engagement. Such an arrangement can connect the exhaust pipe to the air conditioner heat exchange core.

[0014] Furthermore, the air intake mechanism includes a gas filter, a second buffer box, a second Roots flowmeter, an air intake pipe, a second joint and a second limit frame, and the gas filter is fixed to the inside of the box by bolts; a third solenoid valve is fixed to the output end of the gas filter, wherein the third solenoid valve is connected to the gas storage tank; the input end of the gas filter is connected to the second buffer box through an air supply pipe, wherein the second buffer box is fixed to the inside of the box by bolts; a plurality of air intake pipes are fixed to the outer side of the second buffer box, wherein the air intake pipes are respectively adapted to air-conditioning heat exchange cores of different specifications; a second joint is fixed to the other end of the air intake pipe, and the air intake pipes are fixed to the second limit frame by buckling, wherein the second limit frame is fixed to the box by bolts, and such a setting can receive the gas discharged from the air-conditioning heat exchange core and return it to the inside of the gas storage tank, and can detect the flow rate of the gas discharged from the air-conditioning heat exchange core.

The fourth solenoid valve is fixed in the middle of the gas pipe between the gas filter and the second buffer box; the air pressure sensor is fixed to the inside of the second buffer box by bolts. Such a setting can detect whether the air conditioner heat exchange core is damaged.

[0016] Furthermore, the internal structure of the air intake pipe is the same as that of the exhaust pipe, and the internal structure of the second joint is the same as that of the first joint. With this arrangement, the air intake pipe and the exhaust pipe and the second joint and the first joint have the same function.

At this time, the touch panel can respectively compare the values ​​of the first Roots flowmeter and the second Roots flowmeter to receive and display them, and the staff can compare the two values. If the difference between the values ​​is large, it means that there is a possibility of blockage inside the air conditioner heat exchange core;

[0020] Secondly, there is no valve body or other structure between the first Roots flowmeter and the second Roots flowmeter. The exhaust pipe and the intake pipe are both adapted to the air conditioner heat exchange core, and the exhaust pipe and the intake pipe will not be excessively bent, so that the measurement accuracy is high; in addition, the setting of the first joint and the second joint ensures the tight connection between the exhaust pipe and the intake pipe and the air conditioner heat exchange core. This design not only improves the stability of the connection, but also effectively prevents gas leakage at the connection position;

[0021] Finally, after the detection of whether the air-conditioning heat exchange core is blocked is completed, the fourth solenoid valve, the air pump and the second solenoid valve can be closed. At this time, the air pressure inside the second buffer box is the same as the air pressure inside the air-conditioning heat exchange core. Therefore, the air pressure sensor can detect the air pressure inside the second buffer box and transmit the detection value to the touch panel. The staff can observe the air pressure value. If the air pressure continues to decrease, it means that the air-conditioning heat exchange core is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As attached Figure 1 and Figure 2 As shown, the present invention provides an intelligent air-conditioning heat exchange core blockage detector, comprising a box body 1, an air storage tank 2, a fixing frame 3, an exhaust mechanism 4, an air intake mechanism 5, a box door 6, an air supply pipe 7, a touch panel 8 and a switch group 9, wherein the air storage tank 2 is fixed to the inside of the box body 1 through the fixing frame 3; the output end of the air storage tank 2 is connected to the air supply pipe and the input end of the exhaust mechanism 4, wherein the exhaust mechanism 4 is fixed to the inside of the box body 1; the input end of the air storage tank 2 is respectively connected to the air intake mechanism 5 and the air supply pipe 7, wherein the air intake mechanism 5 is fixed to the inside of the box body 1; a first solenoid valve is fixed to the middle of the air supply pipe 7, and a sealing cover is fixed to the other end of the air supply pipe 7, wherein the end of the air supply pipe 7 close to the sealing cover is arranged on the outside of the box body 1; box doors 6 are arranged on the outside of the output ends of the exhaust mechanism 4 and the air intake mechanism 5, wherein the box doors 6 are rotatably connected to the box body 1 through hinges; the outer side of the box body 1 is respectively fixed with a touch panel 8 and a switch group 9 by bolts.

[0032] like Figure 3As shown, the exhaust mechanism 4 includes an air pump 41, a first buffer box 42, a first Roots flowmeter 43, an exhaust pipe 44, a first joint 45 and a first limit frame 46, the air pump 41 is fixed to the inside of the box body 1 by bolts; the input end of the air pump 41 is connected to the air storage tank 2 through an air delivery pipe, and the output end of the air pump 41 is connected to the first buffer box 42 through an air delivery pipe, wherein the first buffer box 42 is fixed to the inside of the box body 1 by bolts; the outer side of the first buffer box 42 is connected to a plurality of exhaust pipes 44 through corresponding second solenoid valves, wherein the exhaust pipes 44 are respectively adapted to air conditioner heat exchange cores of different specifications, and the other end of the exhaust pipes 44 is fixed with a first joint 45; the exhaust pipe 44 are fixed to the first limit frame 46 by snapping, wherein the first limit frame 46 is fixed to the box body 1 by bolts.

Then the gas will pass through the corresponding exhaust pipe 44 into the interior of the air-conditioning heat exchange core, wherein the first Roots flowmeter 43 can detect the gas flow entering the air-conditioning heat exchange core.

[0033] like Figure 4 As shown, the exhaust pipe 44 includes a tube body 441, a reinforcement strip 442 and an anti-bending wire 443.

When in use, the air inlet pipe 56 of the corresponding specification can be removed from the second limit frame 58, and the air inlet pipe 56 is connected to the output end of the air-conditioning heat exchange core through the second joint 57, and then the third solenoid valve is opened. At this time, the gas inside the air-conditioning heat exchange core can enter the second buffer box 53 through the corresponding air inlet pipe 56, and then pass through the gas filter 51 and flow back to the gas storage tank 2. In the above process, the second Roots flowmeter 55 can detect the flow rate of the exhaust gas from the air-conditioning heat exchange core.

[0036] like Figure 6 As shown, the air intake mechanism 5 also includes a fourth solenoid valve 52 and an air pressure sensor 54. The fourth solenoid valve 52 is fixed in the middle of the gas pipe between the gas filter 51 and the second buffer box 53. The air pressure sensor 54 is fixed to the inside of the second buffer box 53 by bolts. When in use, after the detection of whether the air-conditioning heat exchange core is blocked is completed, the fourth solenoid valve 52 can be closed. At this time, the air pressure sensor 54 can detect the air pressure inside the second buffer box 53, thereby detecting whether the air-conditioning heat exchange core is damaged.

[0037] Specifically, the touch panel 8 is connected to the air pump 41, the first Roots flowmeter 43, the second Roots flowmeter 55, the air pressure sensor 54, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve 52 through data lines; the touch panel 8, the switch group 9, the air pump 41, the first Roots flowmeter 43, the second Roots flowmeter 55, the air pressure sensor 54, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve 52 are connected to the switch group through power lines, wherein the other end of the switch group 9 is electrically connected to an external power supply through a power line; the model of the touch panel 8 is Autoface VT6100-WST20, the model of the air pump 41 is PCD01 small silent air pump, the model of the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve 52 are all DMF-Y-50S, the model of the first Roots flowmeter 43 and the second Roots flowmeter 55 are all LGZ-40, and when in use, the working state of the device can be controlled by the touch panel 8.

[0038] The method of using this embodiment includes the following steps:

[0039] 1) In the preparation stage, the exhaust mechanism 4 and the air intake mechanism 5 are first connected to the two ends of the air conditioner heat exchange core through the first joint 45 and the second joint 57 respectively.

[0040] 2) Blockage detection: The gas inside the gas storage tank 2 is transported to the inside of the air-conditioning heat exchange core through the exhaust mechanism 4, and then the gas discharged from the air-conditioning heat exchange core is received by the air intake mechanism 5, and the gas is returned to the inside of the gas storage tank 2. At this time, the touch panel 8 can respectively compare the values ​​of the first Roots flowmeter 43 and the second Roots flowmeter 55 to receive and display them. The staff can compare the two values. If the difference between the values ​​is large, it means that there is a possibility of blockage inside the air-conditioning heat exchange core.

[0041] 3) Damage detection: close the fourth solenoid valve 52, the air pump 41 and the second solenoid valve. At this time, the air pressure inside the second buffer box 53 is the same as the air pressure inside the air-conditioning heat exchange core. Therefore, the air pressure sensor 54 can detect the air pressure inside the second buffer box 53 and transmit the detected value to the touch panel 8. The staff can observe the value of the air pressure. If the air pressure continues to decrease, it means that the air-conditioning heat exchange core is damaged.

[0042] All kinds of components used in this application document are standard parts, and the specific connection methods of each part adopt mature conventional means such as sewing and gluing in the prior art. Each structure adopts conventional materials in the prior art, and no specific description is given here.

[0043] To sum up: the intelligent air-conditioning heat exchange core blockage detector solves the problem of existing air-conditioning heat exchange core blockage detection devices. When in use, it can only detect whether the air-conditioning heat exchange core is completely blocked, but cannot detect whether the air-conditioning heat exchange core is partially blocked. Secondly, the detection efficiency is low. In addition, traditional detection methods rely heavily on manual operation and subjective judgment, which leads to instability and unreliability of detection results.
