Description

Technical Field

[0001] This invention relates to the field of thermal insulation performance testing technology, specifically to a novel device for testing the thermal insulation performance of energy-saving thermal insulation materials. Background Technology

[0002] Thermal insulation mortar is an energy-saving premixed dry powder mortar using various lightweight materials as aggregates. Due to process or equipment issues, the thermal insulation performance of the produced thermal insulation mortar may be inconsistent. Therefore, it is necessary to test the thermal insulation performance of the thermal insulation mortar. A performance testing device for energy-saving thermal insulation mortar is disclosed in utility model publication number CN223192861U, which includes an insulation box and a top cover that is fitted onto the insulation box, solving the problem of inconvenient material removal of thermal insulation mortar blocks in the prior art.

[0003] The above-mentioned device still has the following defects in actual use: 1) When the device retracts the material after testing, the mortar mold needs to move to the discharge port. This process is not only long but also time-consuming, resulting in low actual material retraction efficiency, which is not conducive to continuous testing of the thermal insulation performance of the thermal insulation mortar. 2) When the device is unloading material, the unloading plate needs to be manually pulled out, which is not only time-consuming and labor-intensive, but also has the problem of poor sealing when the thermal insulation mortar is added due to the movable setting of the unloading plate.

[0011] Preferably, a pneumatic unit is provided on the outside of the fan blade. The pneumatic unit includes air pumps arranged at equal intervals. The bottom of the air pump is fixedly connected to the inside of the heat preservation box. A magnetic plate is fixedly connected to the sliding end of the air pump. The outer surface of the magnetic plate abuts against the outer surface of the abutment bar. The exhaust end of the air pump is connected to a connecting pipe. A one-way valve is connected through the inside of the connecting pipe.

[0012] Preferably, the air pump is provided with an air box on its exterior, the outer surface of the air box is fixedly connected to the outer surface of the bracket and the interior of the insulation box, one end of the one-way valve is in through communication with the interior of the air box, an exhaust pipe is in through communication with the interior of the air box, and the interior of the exhaust pipe is rotatably connected to the outer surface of the fan blade.

[0014] Beneficial effects This invention provides a novel testing device for the thermal insulation performance of energy-saving insulation materials. Compared with existing technologies, it has the following advantages: (1) By setting up a material unloading mechanism, the mold shell descends and flips during material unloading, and the close proximity of the mold shell and the conveyor allows the conveyor to carry the fallen thermal insulation mortar, and then the conveyor to discharge the thermal insulation mortar, which shortens the movement stroke and time of the mold shell, thereby improving the overall material unloading efficiency and facilitating continuous testing.

[0015] (2) By setting up a vibrating assembly, the fan blades drive the toothed column to rotate through the airflow, thereby driving the turntable to rotate continuously. The connecting rod is eccentrically connected to the turntable, so that the slide rod moves back and forth along the lifting pipe. The vibration effect is generated by the collision of the lifting pipe and the abutment. Through the action of vibration and gravity, the thermal insulation mortar is facilitated to fall off quickly, thereby further improving the efficiency of material removal.

[0016] (3) By setting up a pneumatic unit, the air pump compresses air synchronously when the mold shell descends, and the high-pressure air is pumped into the air box for storage through the action of the connecting pipe and the one-way valve. When it is discharged through the exhaust pipe, the high-pressure air provides power for the movement of the slide rod through the contact between the high-pressure air and the fan blade. This not only realizes the cyclic use of power, but also improves the continuity of the overall material unloading.

[0017] (4) By setting up a self-driving unit, when the power of compressed air is insufficient to completely remove the thermal insulation mortar, the drive motor drives the drive gear to rotate. Then, through the meshing of the drive gear and the tooth column, the slide bar can be automatically driven to vibrate. The ratchet set up allows the drive gear to rotate independently in the opposite direction when the fan blade is driven, thereby avoiding the problem of damaging the output shaft of the drive motor.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 This invention provides a technical solution: a novel energy-saving thermal insulation material thermal insulation performance testing device. Example 1: Includes an insulation box 1. Stability sensors are installed at the top and bottom inside the insulation box 1, and an existing heating component is installed at the top inside. The insulation box 1 has a material ejection mechanism inside, which includes a mold shell 2. The mold shell 2 is used for bearing and shaping the insulation mortar. The outer surface of the mold shell 2 is fixedly connected to the interior of the insulation box 1. Fixed strips 3 are movably connected to both sides of the outer surface of the mold shell 2, providing support. Rotating shafts 4 are fixedly connected to both sides of the outer surface of the mold shell 2, allowing the mold shell 2 to rotate to adjust the opening direction. This is a preferred embodiment. To reduce the travel of the mold shell 2 and the longitudinal height of the insulation box 1, the rotation radius of the mold shell 2 can be reduced. The mold shell 2 rotates around the rotating shaft 4 so that the opening faces downward for unloading. One end of each rotating shaft 4 is rotatably connected to the interior of the fixed strip 3. A base 6 is provided below the mold shell 2. A piston cylinder 7 is provided between the base 6 and the outer surface of the fixed strip 3. The air passage of the piston cylinder 7 is connected to an external cylinder. The outer surface of the piston cylinder 7 is fixedly connected to the interior of the insulation box 1 through the fixed rod 8. Piston rods 9 are slidably connected to both sides of the interior of the piston cylinder 7. One end of each piston rod 9 is connected to the fixed strip 3. 3 and the outer surface of the base 6 are fixedly connected. The top of the base 6 is fixedly connected to the conveyor 11 via the spring rod 10. The conveyor 11 is driven by an external drive motor and carries and transports the fallen thermal insulation mortar via a belt. The output end of the spring rod 10 has a sliding damping function to buffer the kinetic energy when the thermal insulation mortar falls. The frame of the conveyor 11 is fixedly connected to an inclined connecting plate 12. The connecting plate 12 can guide the conveyed thermal insulation mortar, and its lower side is flush with the lower part of the discharge port of the insulation box 1 to facilitate the discharge of the thermal insulation mortar. One side of the outer surface of the connecting plate 12 is connected to At the discharge port of the insulation box 1, one end of the rotating shaft 4 is fixedly connected to a worm gear 13. The outer surface of the worm gear 13 is rotatably connected to the inside of the fixed bar 3. The outer surface of the worm gear 13 is meshed with a worm 14. The meshing transmission between the worm 14 and the worm gear 13 not only facilitates the flipping of the mold shell 2, but also improves the stability of the mold shell 2 through the self-locking function. One end of the worm 14 is rotatably connected to the body of the fixed bar 3 and extends to the outside of the fixed bar 3. One end of the worm 14 is fixedly connected to an adjusting gear 15. The outer surface of the adjusting gear 15 is meshed with a rack 16. The outer surface of the rack 16 is fixedly connected to the outer surface of the fixed bar 8.

[0022] In this embodiment, after the test is completed, the external cylinder extracts the air from the piston cylinder 7, using negative pressure to bring one end of the two piston rods 9 closer together. This causes the fixing bar 3 and the base 6 to move the mold shell 2 and the conveyor 11 closer together. After the mold shell 2 descends a certain distance, the adjusting gear 15 contacts the rack 16. As the mold shell 2 continues to descend, the adjusting gear 15 rotates the worm gear 14. Through the meshing transmission of the worm gear 14 and the worm wheel 13, the rotating shaft 4 drives the mold shell 2 to rotate, thereby opening the mold shell 2. The mortar is placed above the downward-facing conveyor 11, and then gravity causes the insulating mortar to fall onto the conveyor 11. At the same time, the output end of the spring rod 10 buffers the kinetic energy of the insulating mortar falling by extending and retracting. Then, the cylinder inflates the piston cylinder 7, causing the mold shell 2 and the conveyor 11 to reset, and aligning the connecting plate 12 with the lower part of the discharge port. Then, the insulating mortar is conveyed by the conveyor 11 and falls onto the inclined connecting plate 12, and then slides down by gravity, thus being discharged to the outside of the insulation box 1 through the discharge port.

[0023] Example 2: A vibration assembly 5 is provided on the outside of the mold shell 2. The vibration assembly 5 includes a lifting pipe 51, which is formed by welding a rectangular tube and a straight plate. A bracket 510 is fixedly connected to the outer surface of the lifting pipe 51, providing fixed support for the lifting pipe 51. A sliding rod 52 is slidably connected inside the lifting pipe 51. A turntable 53 is rotatably connected to the outer surface of the lifting pipe 51. The outer arc surface of the turntable 53 is provided with teeth, or a gear can be used directly instead. A connecting rod 54 is rotatably connected to the outer surface of the turntable 53. The connecting rod 54 is connected by a pin, and one end is eccentrically set on the surface of the turntable 53. One end of the connecting rod 54 rotates with one end of the sliding rod 52. The sliding rod 52 is movably connected to a stop bar 55 at the other end. The stop bar 55 acts as a spacer to prevent the sliding rod 52 from directly contacting the mold shell 2, thus avoiding damage to the mold shell 2. When the mold shell 2 is open upwards, the stop bar 55 is located on the side of the mold shell 2 away from the sliding rod 52. The outer surface of the stop bar 55 is fixedly connected to the outer surface of the mold shell 2. The turntable 53 is provided with a fan blade 56 on its outside. The fan blade 56 obtains the power to drive the sliding rod 52 by contacting the flowing air. The shaft end of the fan blade 56 is rotatably connected to the outer surface of the lifting tube 51. The shaft end of the fan blade 56 is fixedly connected to a toothed column 58, and the outer surface of the toothed column 58 meshes with the outer surface of the turntable 53.

[0024] In this embodiment, the abutment strip 55 follows the flipping of the mold shell 2 to be located on the side close to the slide rod 52, and continues to descend with the mold shell 2. Then, when the abutment strip 55 and the slide rod 52 are aligned left and right, the mold shell 2 and the conveyor 11 stop moving. Then, the fan blade 56 drives the toothed column 58 to rotate by contacting the flowing air. Through the meshing of the teeth of the toothed column 58 and the turntable 53, the turntable 53 rotates. Then, through the eccentric connection between the connecting rod 54 and the turntable 53, the slide rod 52 is driven to slide back and forth along the lifting pipe 51. During the sliding, through contact with the abutment strip 55, the mold shell 2 vibrates to achieve the shedding of the thermal insulation mortar.

[0025] Example 3: A pneumatic unit 57 is provided on the outside of the fan blade 56. The pneumatic unit 57 includes air pumps 571 arranged at equal intervals. Multiple air pumps 571 are arranged to ensure air pressure and flow. The bottom of the air pump 571 is fixedly connected to the inside of the insulation box 1. A magnetic plate 572 is fixedly connected to the sliding end of the air pump 571. There is a contact and magnetic attraction between the magnetic plate 572 and the abutment bar 55. The magnetic force is greater than the air pressure force when the piston of the air pump 571 returns to its original position. The outer surface of the magnetic plate 572 abuts against the outer surface of the abutment bar 55. The exhaust end of the air pump 571 is connected to a connecting pipe 573. An internal one-way valve 574 is connected, which allows compressed air to flow in one direction. An air box 575 is provided on the outside of the air pump 571. The air box 575 is made of a material with good airtightness and pressure resistance. The outer surface of the air box 575 is fixedly connected to the outer surface of the bracket 510 and the inside of the insulation box 1. One end of the one-way valve 574 is connected to the inside of the air box 575. An exhaust pipe 576 is connected to the inside of the air box 575. A solenoid valve (not shown in the figure) is provided on the exhaust pipe 576 and is electrically connected to the external control circuit. The inside of the exhaust pipe 576 is rotatably connected to the outer surface of the fan blade 56.

[0026] In this embodiment, when the abutment bar 55 continues to descend with the mold shell 2 after flipping, it abuts against the magnetic plate 572, thereby pressing down the piston of the air pump 571, so that the air pump 571 compresses the air. The compressed air is combined and transported through the connecting pipe 573 and the one-way valve 574, and then enters the air box 575 for storage. When vibration is needed for material removal, the solenoid valve on the exhaust pipe 576 opens, and the air in the air box 575 is discharged through the exhaust pipe 576. During the discharge process, the air pump 56 is driven to rotate by contact with the fan blade 56. At the same time, when the mold shell 2 rises and resets, the magnetic attraction between the magnetic plate 572 and the abutment bar 55 causes the magnetic plate 572 to drive the piston of the air pump 571 to reset.

[0027] Example 4: A self-drive unit 59 is provided on the outside of the gear column 58. The self-drive unit 59 includes a drive motor 591. The drive motor 591 is electrically connected to an external control circuit. The outer surface of the drive motor 591 is fixedly connected to the inside of the insulation box 1. A ratchet 592 is fixedly connected to the output end of the drive motor 591. The unidirectional driving action of the ratchet 592 can protect the output shaft of the drive motor 591. A drive gear 593 is fixedly connected through the outer surface of the ratchet 592. The outer surface of the drive gear 593 meshes with the outer surface of the gear column 58.

[0028] In this embodiment, when the air inside the air box 575 is completely discharged, but the thermal insulation mortar inside the mold shell 2 has not completely fallen off, the drive motor 591 drives the drive gear 593 to rotate through the ratchet 592. Through the meshing of the drive gear 593 and the tooth column 58, the slide bar 52 is driven to continue vibrating. When the fan blade 56 rotates, the drive gear 593 idles through the ratchet 592, thereby avoiding damage to the output shaft of the drive motor 591.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
