[0001] The present invention relates to the field of air conditioning separation technology, and more particularly to an air conditioning device for a laboratory. Background Art

[0002] The main purpose of using air conditioning equipment in laboratories is to control air quality and cleanliness and remove harmful substances. Air conditioning equipment is usually equipped with an air filtration system that can separate and filter dust and harmful substances in the external air to ensure the cleanliness of the air in the laboratory.

[0003] In the existing public documents, patent announcement number CN118320544A discloses a laboratory room ventilation and dust removal device and a dust removal method thereof. The device is provided with a plurality of positioning lugs fixed on the top surface of the top plate, and a positioning shaft is rotatably inserted into the top end of the positioning lug, and the outer end of the positioning shaft is connected to the corresponding rectangular slide bar through a crank connecting rod mechanism. The invention can adjust the size of the air inlet according to actual needs, has the function of improving indoor air quality, prevents dust from affecting the operation of the unit equipment, and prolongs its service life. However, the device still has the following problems.

[0004] When the air conditioning equipment adjusts the laboratory air quality, it can separate and filter the dust and impurities in the air. However, as the use time increases, a large amount of dust and impurities in the air will continue to clog the filter separation filter element of the air conditioning equipment, which will not only make it difficult to stably regulate the air, but also cause a lot of dust to accumulate in the filter separation filter element, making it easy for bacteria to breed, making it difficult to switch to a normal state of separating and filtering dust and impurities in time. For this reason, a laboratory air conditioning equipment is needed. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: an air conditioning equipment for a laboratory, comprising an air pipe, a first main valve and a guide pipe, wherein the first main valve is threadedly connected to one end of the air pipe, the guide pipe is threadedly connected to one end of the first main valve, and a separation switching detection mechanism is provided at the top of the guide pipe; the separation switching detection mechanism comprises a separation tank fixedly arranged at the top of the guide pipe, and a second main valve is fixedly connected to one side of the outer wall of the separation tank, and one end of the second main valve is fixedly connected to a laboratory butt joint pipe; a separation filter element is fixedly installed on the inner wall of the separation tank, a distance sensor is provided below the separation filter element, an electric cylinder is fixedly connected to one side of the distance sensor, a rotating shaft is fixedly installed at the bottom end of the electric cylinder, and a position shifting motor is fixedly connected to the bottom end of the rotating shaft; a switching recovery mechanism is provided on one side of the outer wall of the air pipe; a cut-off component is provided on the upper surface of the laboratory butt joint pipe.

[0006] Preferably, the guide tube is connected to the separation tank, and the inner walls of the guide tube and the separation tank are both smooth surfaces. A pillar is installed on one side of the position-shifting motor, and the guide tube and the position-shifting motor are fixedly connected to the pillar; a guide cone is fixedly installed on the bottom end of the position-shifting motor, and the bottom cross-sectional area of ​​the guide cone is smaller than the top cross-sectional area. The other end of the air duct is fixedly connected to a booster fan, and the input end of the booster fan is threadedly connected to an air intake pipe. A controller is fixedly installed on one side of the laboratory butt joint, a separation filter cartridge is fixedly installed on the inner wall of the separation tank, and a cover plate is threadedly connected to the top outer wall of the separation tank.

[0007] When this technology is used, long-term use will cause a large amount of dust and impurities to accumulate at the bottom of the separation filter. The displacement motor drives the shaft to rotate forward one circle and then reverse one circle. The electric cylinder drives the distance sensor to rotate forward one circle and then reverse one circle. The electric cylinder pushes the distance sensor to move right and then left. In this way, the distance sensor can sense the dust and impurities at the bottom of the separation filter. When the sensed distance value is the same as the distance value set by the controller that needs to be replaced, the separation filter needs maintenance and repair.

[0008] Preferably, the switching recovery mechanism includes a first switching valve fixedly arranged on one side of the outer wall of the air pipe; one end of the first switching valve is fixedly connected to a shunt pipe, and a connected filter tank body is fixedly installed on the top of the shunt pipe, and a second switching valve is threadedly connected to the top of the filter tank body, and the second switching valve is fixedly connected to the laboratory docking pipe; a switching filter element is fixedly installed on the inner wall of the filter tank body.

[0009] When the technology is in use, the first main valve and the second main valve are closed by the controller, and the first switching valve and the second switching valve are opened by the controller at the same time. The air is poured into the shunt pipe through the first switching valve, and then into the filter tank body through the shunt pipe, and then enters the second switching valve through the filter tank body, and the separated air is introduced into the laboratory docking pipe.

[0010] Preferably, the truncation component includes a micro-electric cylinder fixedly arranged on the upper surface of the laboratory butt joint pipe, the output end of the micro-electric cylinder is fixedly connected to a push rod, one end of the push rod is fixedly connected to a linkage block, and the bottom end of the linkage block is fixedly installed with a sealing block; a sealing plate is fixedly connected to one side of the sealing block, and the laboratory butt joint pipe and the sealing plate are slidably connected, the outer wall of the sealing plate is slidably connected to a guide groove frame, and the guide groove frame is fixedly connected to the laboratory butt joint pipe; the inner wall of the guide groove frame is provided with a groove body, and the sealing plate is slidably connected to the groove body.

One side of the sealing plate is arranged parallel to one side of the inner wall of the guide groove frame, and the sealing plate is made of carbon fiber material.

[0011] When this technology is in use, the controller starts the micro-electric cylinder to drive the push rod to move right, and the linkage block drives the sealing block to move right. The sealing plate can be guided to move right along the inner wall of the guide groove frame, and the inner wall of the groove body can guide the sealing plate to achieve a plug-in operation.

The distance sensor can realize distance sensing of dust and impurities at the bottom end of the separation filter element. If the sensed distance value is the same as the distance value set by the controller that needs to be replaced, the separation filter element needs maintenance and repair. In this way, it can be timely known that a large amount of dust and impurities are accumulated at the bottom of the separation filter element, so as to timely switch to another channel for air conditioning operation, and can timely switch to the normal separation and filtration state of dust and impurities.

[0013] 2. The present invention adopts a switching recovery mechanism. The first main valve and the second main valve are closed by the controller. The controller opens the first switching valve and the second switching valve. The pressurized air is delivered to the first switching valve through the air pipe, and enters the second switching valve through the filter tank.

[0014] 3. The present invention utilizes a cut-off assembly, and the controller starts the micro-electric cylinder to drive the push rod to move right, and the linkage block drives the sealing block to realize the right movement operation, and the sealing block causes the sealing plate to move right, and the inner wall of the groove body can realize the guiding plug-in operation of the sealing plate, and the sealing plate and the guide groove frame are sealed to prevent dirty air from entering the laboratory docking pipe, and another channel is switched in time for air conditioning operation, and it can be switched in time to the normal separation and filtration state of dust and impurities.

[0031] The working principle of the laboratory air conditioning equipment of the present invention is as follows: Step 1. When the laboratory air is adjusted, firstly, the top end of the laboratory docking tube 6 is docked on the laboratory air intake channel, and sealant is applied at the connection of the laboratory docking tube 6, so that the controller 15 turns off and starts the micro-electric cylinder 21, and the micro-electric cylinder 21 pushes the push rod 26 to move left, and the push rod 26 drives the linkage block 22 to move left, and the linkage block 22 makes the sealing block 23 move left, and the sealing block 23 drives the sealing plate 24 to move left, and the sealing plate 24 moves left along the groove body 27, and the sealing plate 24 is separated from the guide groove frame 25.

[0032] Open the passage of the laboratory docking pipe 6, so that the controller 15 starts the booster fan 14, and the booster fan 14 allows the external air to enter the air pipe 1 along the air inlet pipe 28, and enter the first main valve 2 from the air pipe 1, open the first main valve 2 and the second main valve 5, and close the first switching valve 16 and the second switching valve 19 at the same time. In this way, the external air enters the guide pipe 3 along the first main valve 2, and is poured into the separation tank 4 from the guide pipe 3, and the dust and impurities are separated and filtered through the separation filter element 7 and the separation filter cartridge 29, and the cover plate 30 is pressed on the top of the separation tank 4 to increase the sealing of the top of the separation tank 4. The clean air is adjusted to enter the laboratory docking pipe 6 along the second main valve 5, and enter the laboratory along the laboratory docking pipe 6.

[0033] Step 2: During the separation switching test, long-term use will cause a large amount of dust and impurities to accumulate at the bottom of the separation filter element 7. The controller 15 starts the displacement motor 11, and the support 12 supports the displacement motor 11. The guide cone 13 guides the air laterally, so that the displacement motor 11 drives the shaft 10 to rotate forward one circle and then reverse one circle, and the shaft 10 drives the electric cylinder 9 to rotate forward one circle and then reverse one circle, and the electric cylinder 9 drives the distance sensor 8 to rotate forward one circle and then reverse one circle, so that the distance sensor 8 can reciprocate along the bottom of the separation filter element 7. At the same time, the electric cylinder 9 pushes the distance sensor 8 to move right and then left, so that the distance sensor 8 can sense the distance of the dust and impurities at the bottom of the separation filter element 7. When the sensed distance value is the same as the distance value set by the controller 15 and needs to be replaced, the separation filter element 7 needs maintenance and repair, and the separation filter element 7 cannot be used normally.

[0035] Step 4, when switching and separating, the first main valve 2 and the second main valve 5 are closed by the controller 15, and at the same time, the controller 15 opens the first switching valve 16 and the second switching valve 19, and the pressurized air is delivered to the first switching valve 16 through the air pipe 1, and is poured into the diverter pipe 17 by the first switching valve 16, and is poured into the filter tank body 18 by the diverter pipe 17, and enters the second switching valve 19 through the filter tank body 18, and passes through the switching filter element 20 inside the filter tank body 18 to realize the dust separation operation, so that the separated clean air is introduced into the laboratory docking pipe 6, and the clean air is continued to be transported.
