Description

Technical Field

[0001] The invention belongs to the technical field of mixer detection, and in particular relates to a mixer air tightness detection device. Background Art

[0002] In modern industrial manufacturing, mixers, as a key fluid handling equipment, are widely used in chemical, food, medicine and other fields. Their performance stability and safety are directly related to production efficiency and product quality. The air tightness detection of mixers is an important link to ensure their normal operation and prevent medium leakage. However, existing mixers face many challenges when detecting air tightness.

[0003] First of all, the mixer has extremely high requirements for the sealing performance of the device during the air tightness test. Once the seal is not tight, it will not only lead to inaccurate test results, but also may cause medium leakage during actual use, affecting production safety and environmental protection. Existing sealing methods, such as rubber sealing rings, can provide good sealing effects at room temperature, but in cold environments, the rubber material will harden due to the decrease in temperature, resulting in a weakened sealing effect, which increases the difficulty and uncertainty of air tightness testing.

[0004] Secondly, the air tightness test of traditional mixers usually adopts a single pressure test method, that is, judging whether it is leaking by observing the changes in the internal pressure of the mixer. Although this method is simple and direct, it is difficult to cope with complex and changing testing needs.

[0005] Finally, as mixer designs become increasingly complex and diverse, higher requirements are placed on the flexibility of detection equipment. Especially for large or irregularly shaped mixers, traditional static detection methods often fail to fully cover all potential leak points, and most existing detection equipment lacks the ability to dynamically adjust, limiting its application in complex mixer detection.

[0024] Embodiment 1

[0025] Please see attached Figures 1 to 10 As shown, it is the first embodiment of the present invention, which provides a mixer air tightness detection device, which is applied to the air tightness detection of the mixer, including a base 10, a bracket 11 and a flange 12 are fixed at both ends of the top of the base 10, an active disk 13 is rotatably connected to the inside of the bracket 11 through a ball bearing, a driven disk 14 is slidably connected to the inside of the flange 12, an electric push cylinder 15 is fixed to the end of the flange 12 away from the bracket 11, and the output end of the electric push cylinder 15 passes through the inside of the flange 12, and the output end of the electric push cylinder 15 is fixedly connected to the driven disk 14, and also includes: Two extrusion assemblies 20, the two extrusion assemblies 20 are respectively assembled at the ends of the active disk 13 and the driven disk 14 close to each other, the extrusion assemblies 20 include a rubber pad 21, an air bag 22 and an air nozzle 23, the rubber pad 21 in the extrusion assembly 20 connected to the active disk 13 is fixed to the end of the active disk 13 close to the driven disk 14, the rubber pad 21 in the extrusion assembly 20 connected to the driven disk 14 is rotatably connected to the end of the driven disk 14 close to the active disk 13 through a ball bearing, the ends of the rubber pads 21 in the two extrusion assemblies 20 close to each other are provided with a clamping groove, the inner wall of the clamping groove is provided with a concave groove, the air bag 22 is fixed inside the concave groove, the air nozzle 23 is fixed to the outside of the rubber pad 21, and the air nozzle 23 and the air bag 22 are connected to each other; The oiling assembly 30 is assembled inside the base 10; A driving assembly 40, the driving assembly 40 is mounted on the top of the base 10, and the driving assembly 40 is connected to the extrusion assembly 20 mounted on the bracket 11; Among them, the two extrusion components 20 can clamp the mixer and seal the two ends of the mixer respectively, and the oiling component 30 can apply maintenance grease on the surface of the clamping groove, fill the small cracks in the clamping groove with the maintenance grease and form a sealing oil film.

[0026] Furthermore, the maintenance grease can be any one of the following items: silicone grease, fluorosilicone grease, lithium-based grease, silicone oil or other items that can fill small cracks on the rubber surface and form an oil film. Preferably, in this embodiment, the maintenance grease is preferably silicone oil.

[0027] Here, an air source component and a control component are used in conjunction with the device. An air intake pipe is provided inside the active disk 13, and the air intake pipe passes through the inside of the rubber pad 21. The end of the air intake pipe away from the rubber pad 21 is rotatably connected to a pressure gauge. The air source component and the input end of the pressure gauge as well as the air source component and the air nozzle 23 are connected by a spiral hose. After the air source component is started, gas can be input or extracted into the air intake pipe and / or the inside of the airbag 22 respectively. At the same time, when the two rubber pads 21 clamp and seal the two ends of the mixer, the air pressure change inside the mixer can be checked by checking the pressure gauge, and whether there is a leak can be determined in turn. The control component and the electric push cylinder 15 as well as the control component and the drive component 40 are electrically connected by wires, and the control component can independently control the operation of the electric push cylinder 15 and the drive component 40 respectively.

[0028] In this embodiment, before the test, the oiling assembly 30 is used to apply maintenance grease to the mutually adjacent sides of the two groups of rubber pads 21, and the maintenance grease is used to fill the fine cracks on the clamping grooves inside the rubber pads 21 and form a sealing oil film, and the mixer is placed between the two rubber pads 21, and then the electric push cylinder 15 is operated, and the electric push cylinder 15 pushes the driven disk 14 to move toward the mixer, and the two rubber pads 21 cooperate to clamp the mixer and block both ends of the mixer, so that a sealed space is formed inside the mixer, and the air source assembly is started, and the air is injected into the mixer and the air bag 22 through the air inlet pipe and the air nozzle 23 respectively. When gas is introduced, the airbag 22 expands, so that the two airbags 22 and the two ends of the outer side of the mixer are tightly fitted respectively. Through the cooperation of the two airbags 22, a secondary seal is formed on the mixer to improve the accuracy of the air tightness detection of the mixer. At the same time, after a proper amount of gas is injected into the mixer, the gas source component is closed, and the pressure inside the mixer is observed by the pressure gauge. If the mixer pressure remains unchanged, the mixer has good air tightness. If the mixer pressure drops, the mixer has air leakage. At the same time, the driving component 40 will drive the active disk 13 and the mixer to flip over, so that the staff can have an all-round view of the outer surface of the mixer to facilitate the inspection of whether there are leaks on the surface.

[0029] It should be noted that since a spiral hose is installed between the air source assembly and the air nozzle 23, in order to avoid pipeline winding, in this embodiment, when the drive assembly 40 drives the active disk 13 and the mixer to flip, the movement mode of the mixer is reciprocating rotation, and the angle range of a single rotation is 0 to 180°.

[0030] Next, please refer to Figure 4 The extrusion assembly 20 further includes a heat conducting plate 24 and a heating wire 25. The heat conducting plate 24 is fixed inside the rubber pad 21, the heating wire 25 is fixed inside the heat conducting plate 24, and the heat conducting wire and the control assembly are electrically connected via a rotary joint.

[0031] In this embodiment, when performing air tightness detection, if the ambient temperature is too low, causing the rubber on the surface of the rubber pad 21 to harden, the control component starts the heating wire 25 to generate heat, and transfers the heat to the entire rubber pad 21 through the heat conducting plate 24, so that the rubber part on the rubber pad 21 is heated and softened, eliminating the rubber hardening caused by the low temperature, and ensuring the fitting and sealing effect when clamping the mixer.

[0032] It should be noted that after the heating wire 25 is working, the temperature of the heating wire 25 can be regulated by the control module. In the present embodiment, the heating wire 25 can heat the rubber pad 21 to 20°C-30°C, so that the rubber pad 21 can maintain its elastic state in a low temperature environment. At the same time, it can also avoid the aging of the rubber pad 21 due to excessively high temperature.

[0033] Next, please refer to Figures 8 to 10 A liquid storage chamber 16 is provided inside the base 10, an injection port is provided at the upper end of the liquid storage chamber 16, and maintenance grease is injected into the liquid storage chamber 16. A dipping groove is provided inside the base 10 and at the upper end of the liquid storage chamber 16. The oiling assembly 30 includes a liquid absorbing strip 31, a sponge pad 32 and a wiping plate 33. The liquid absorbing strip 31 is fixed inside the liquid storage chamber 16, and the upper end of the liquid absorbing strip 31 passes through the liquid storage chamber 16 and extends to the outside of the liquid storage chamber 16. The sponge pad 32 is fixed inside the dipping groove, and the sponge pad 32 and the liquid absorbing strip 31 are in contact with each other. The wiping plate 33 is arranged on one side of the bracket 11 through an elastic rope, and the wiping plate 33 and the dipping groove as well as the wiping plate 33 and the sponge pad 32 are adapted to each other. Here, an observation slot is provided on one side of the liquid storage chamber 16, and an observation plate is fixed inside the observation slot, and the material of the observation plate is a transparent material. The material of the observation plate can be one of the following materials: PVC, tempered glass or other transparent materials. Specifically, in this embodiment, the material of the observation plate is preferably tempered glass; The material of the liquid absorbent strip 31 is preferably a porous material, and the liquid absorbent strip 31 contains a large number of tiny pores or capillaries. The lower end of the wiping plate 33 is fixed with oil-absorbing felt.

[0034] Furthermore, when the lower end of the liquid-absorbing strip 31 is immersed in the maintenance grease, the pores or capillaries inside the liquid-absorbing strip 31 can form a capillary phenomenon, so that the maintenance grease (such as silicone oil) inside the liquid storage chamber 16 can spontaneously rise or fall in the narrow pipe or pore, thereby allowing the maintenance grease inside the liquid storage chamber 16 to be transported to the sponge pad 32; A handle is provided on the wiping plate 33 for easy picking up of the wiping plate 33. When the wiping plate 33 is inserted into the dipping groove on the base 10, the wiping plate 33 will squeeze the sponge pad 32 to squeeze out the maintenance grease inside it, and absorb the maintenance grease through the oil-absorbing felt, and coat the surface of the rubber pad 21 with grease through the wiping plate 33.

[0035] In this embodiment, before extrusion sealing, the wiping plate 33 is held and dipped into the maintenance grease on the sponge pad 32, and the grease is applied to the surfaces of the opposite sides of the two groups of rubber pads 21 to fill the small cracks on the surface and form an oil film to improve the sealing performance and avoid affecting the accuracy of detection due to air leakage in the clamping part.

[0036] Next, please refer to Figures 5 to 7The driving assembly 40 includes a motor 41, a gear 42, a gear ring 43 and a chain 44. The motor 41 is fixed to the top of the base 10, and the motor 41 and the control assembly are electrically connected through a wire. The gear 42 is fixed to the output end of the motor 41, the gear ring 43 is fixed to the outer edge of the active disk 13, and the chain 44 is assembled on the outside of the gear 42 and the gear ring 43.

[0037] It should be noted that the bracket 11 is fixedly connected to a protective shell at the outer side of the chain 44, and the output shaft of the motor 41 passes through the protective shell and is connected to the gear 42. The motor 41 is preferably a servo motor. In this embodiment, the motor 41 drives the gear ring 43 to rotate reciprocatingly, and the angle range of a single rotation of the gear ring 43 is 0 to 180°.

[0038] In this embodiment, during the detection process, when the mixer surface needs to be inspected, the motor 41 is started, and the motor 41 drives the gear 42 to rotate, thereby driving the chain 44 and the gear ring 43 to reciprocate, and the gear ring 43 drives the active disk 13 and the mixer to rotate, thereby driving the rubber pad 21 connected to the driven disk 14, and the driven disk 14 to rotate together, so as to realize the reciprocating rotation of the mixer, so that the staff can inspect the surface of the mixer.

[0039] Embodiment 2

[0040] Please refer again Figures 10 to 13 This embodiment is a further optimization based on the first embodiment, specifically: The spray assembly 50 includes a processing table 51. A collecting tank 17 is provided inside the base 10. The processing table 51 is fixedly connected to the bottom of the base 10. A mounting frame 52 is fixedly provided on the upper end of the processing table 51. An electric guide rail 53 is installed on the top of the mounting frame 52. A spray nozzle 54 is installed on the lower end of the electric guide rail 53. A liquid storage tank 55 and a water pump 56 are fixedly connected to the lower end of the processing table 51. A liquid outlet is provided on the outer side of the liquid storage tank 55. A liquid infusion tube 57 is installed between the liquid outlet and the input end of the water pump 56 and between the output end of the water pump 56 and the spray nozzle 54. A reflux port is provided at the upper end of the liquid storage tank 55 , and the reflux port is matched with the collecting tank 17 .

[0041] The reflux port is provided so that the liquid sprayed on the mixer surface can flow back to the liquid storage tank 55 through the reflux port for recycling; A filter is fixed inside the reflux port. The filter can filter the refluxed liquid so that the liquid can be recycled and the utilization rate of resources can be improved. The infusion tube 57 is a spiral hose.

[0042] Furthermore, the spiral hose can be extended and retracted when the electric guide rail 53 drives the spray nozzle 54 to move, so that the infusion tube 57 can still transport liquid during the movement of the spray nozzle 54.

[0043] It should be noted that the inner cavity of the liquid storage tank 55 is provided with a liquid level sensor, which is intended to detect the water level change in the liquid storage tank 55 through the liquid level sensor, so as to facilitate timely addition of liquid for detection.

[0044] In this embodiment, before performing the air tightness test, the mixer air tightness test equipment can be installed on the processing table 51, and the collection tank 17 of the base 10 is connected to the liquid storage tank 55, so that the air tightness test is additionally performed by a spraying liquid test method. At this time, liquid needs to be added to the liquid storage tank 55, and then the water pump 56 is operated to extract the liquid in the liquid storage tank 55 and input it into the infusion tube 57, so that the infusion tube 57 connected to the spray nozzle 54 sprays liquid onto the surface of the mixer. If there are tiny holes in the mixer, the liquid will be blown to form tiny bubbles or blow the liquid away, so that it can be intuitively checked whether there are holes in the mixer and the location of the holes, and the sprayed liquid will flow back to the liquid storage tank 55 through the collection tank 17 on the base 10 for secondary testing to avoid waste of resources.

[0045] It should be noted that, in the present embodiment, the liquid injected into the liquid storage tank 55 is soapy water. If there are gaps on the surface of the mixer, the gas inside the mixer will leak out, which can cause the soapy water to form bubbles, making it easier for staff to observe.

[0046] The working principle of the present invention is as follows: before performing extrusion sealing, hold the wiping plate 33 and dip the maintenance grease on the sponge pad 32, and apply the grease to the surface of the opposite side of the two groups of rubber pads 21, fill the small cracks on the surface, and form an oil film to improve the sealing performance. Then the electric push cylinder 15 is operated to push the driven disk 14 to move, clamping the mixer between the two groups of rubber pads 21. At this time, the air nozzle 23 is connected to the external air source and connected to the airbag 22, so that the airbag 22 expands and fits the outside of the mixer, further improving the sealing effect. Then the active disk 13 is externally connected to the air pump, and the gas is injected or extracted into the mixer through the air inlet pipe, so that the air pressure inside the mixer changes, and the change in air pressure is checked to determine whether there is a leak in the mixer. When the mixer needs to be sprayed for inspection, the air tightness inspection equipment of the mixer can be installed on the processing table 51, and the collecting tank 17 of the base 10 is connected to the liquid storage tank 55, so that the air tightness inspection is additionally conducted by spraying liquid. At this time, liquid needs to be added to the liquid storage tank 55, and then the water pump 56 is operated to extract the liquid in the liquid storage tank 55 and input it into the infusion tube 57, so that the infusion tube 57 connected to the spray nozzle 54 sprays liquid onto the surface of the mixer. If there are tiny holes in the mixer, the liquid will be blown to form tiny bubbles or blow the liquid away, so that it can be intuitively checked whether there are holes in the mixer and the location of the holes, and the sprayed liquid will flow back to the liquid storage tank 55 through the collecting tank 17 on the base 10 for secondary inspection to avoid waste of resources. At the same time, the motor 41 drives the gear 42 to rotate, thereby driving the chain 44 and the gear ring 43 to rotate, and the gear ring 43 drives the active disk 13 and the mixer to rotate, thereby realizing the flipping of the mixer, and then the outer surface of the mixer can be completely viewed, thereby improving the accuracy and rigor of the detection.

[0047] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
