Description

Technical Field

[0001] The present invention belongs to the technical field of mixer detection, and particularly relates to a mixer airtightness detection device. Background Art

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

[0003] Firstly, during the airtightness detection process of mixers, there are extremely high requirements for the sealing performance of the device. Once the sealing is not tight, it will not only lead to inaccurate detection results but also may cause medium leakage during actual use, affecting production safety and environmental protection. Existing sealing means, such as rubber sealing rings, although can provide good sealing effects at normal temperatures, but in cold environments, the rubber material will harden due to temperature reduction, resulting in weakened sealing effects, increasing the difficulty and uncertainty of airtightness detection.

[0004] Secondly, the airtightness detection of traditional mixers usually adopts a single pressure test method, that is, by observing the change in the internal pressure of the mixer to determine whether it leaks. Although this method is simple and direct, it is difficult to meet complex and variable detection requirements.

[0005] Finally, with the increasing complexity and diversification of mixer designs, higher requirements are put forward for the flexibility of detection equipment. Especially for large or irregularly shaped mixers, traditional static detection methods often cannot comprehensively cover all potential leakage points, and most existing detection equipment lacks the ability of dynamic adjustment, restricting its application in the detection of complex mixers.

[0044] Embodiment 1

[0045] Please refer to the attached Figures 1 to 10As shown in the figure, this is the first embodiment of the present invention. This embodiment provides a mixer airtightness detection device, which is applied to the airtightness detection of a mixer. It includes a base 10. At both ends of the top of the base 10, a bracket 11 and a flange 12 are respectively fixed. Inside the bracket 11, a driving disc 13 is rotatably connected through a ball bearing. Inside the flange 12, a driven disc 14 is slidably connected. At one end of the flange 12 away from the bracket 11, an electric push cylinder 15 is fixed. The output end of the electric push cylinder 15 penetrates through the inside of the flange 12, and the output end of the electric push cylinder 15 is fixedly connected to the driven disc 14. It further includes:

[0046] Two extrusion components 20. The two extrusion components 20 are respectively assembled at one end of the driving disc 13 and the driven disc 14 close to each other. The extrusion component 20 includes a rubber pad 21, an airbag 22 and a nozzle 23. The rubber pad 21 in the extrusion component 20 connected to the driving disc 13 is fixed at one end of the driving disc 13 close to the driven disc 14. The rubber pad 21 in the extrusion component 20 connected to the driven disc 14 is rotatably connected through a ball bearing at one end of the driven disc 14 close to the driving disc 13. At one end of the rubber pads 21 of the two extrusion components 20 close to each other, a clamping groove is provided. An concave groove is provided on the inner wall of the clamping groove. The airbag 22 is fixed inside the concave groove. The nozzle 23 is fixed on the outside of the rubber pad 21, and the nozzle 23 is in communication with the airbag 22;

[0047] An oiling component 30, which is assembled inside the base 10;

[0048] A driving component 40, which is assembled on the top of the base 10, and the driving component 40 is connected to the extrusion component 20 assembled on the bracket 11;

[0049] Among them, the two extrusion components 20 can clamp the mixer and form seals at both ends of the mixer respectively. The oiling component 30 can apply maintenance grease on the surface of the clamping groove. The maintenance grease fills the fine cracks in the clamping groove and forms a sealing oil film.

[0050] 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 the fine cracks on the rubber surface and form an oil film. Preferably, in this embodiment, the maintenance grease is preferably silicone oil.

[0051] Here, an air source assembly and a control assembly are also used in conjunction with the device. An air inlet pipe is provided inside the active disk 13, and the air inlet pipe passes through the inside of the rubber pad 21. One end of the air inlet pipe away from the rubber pad 21 is rotatably connected to a pressure gauge. The input ends of the air source assembly and the pressure gauge, as well as between the air source assembly and the air nozzle 23, are connected by spiral hoses. After the air source assembly is started, it can input or extract gas into or from the air inlet pipe or / and the airbag 22 respectively. At the same time, when the two rubber pads 21 clamp and seal both ends of the mixer, the pressure change inside the mixer is checked by looking at the pressure gauge to determine whether there is a leakage. The control assembly is electrically connected to the electric push cylinder 15 and the control assembly and the drive assembly 40 through wires, and the control assembly can independently control the operation of the electric push cylinder 15 and the drive assembly 40 respectively.

[0052] In this embodiment, before the detection, the lubricating oil application assembly 30 applies maintenance grease to the mutually approaching surfaces of the two rubber pads 21. The maintenance grease fills the fine cracks in the clamping grooves inside the rubber pads 21 and forms a sealing oil film. The mixer is placed between the two rubber pads 21. Subsequently, the electric push cylinder 15 operates, and the driven disk 14 is pushed by the electric push cylinder 15 to move towards the mixer. Through the cooperation of the two rubber pads 21, the mixer is clamped and both ends of the mixer are sealed, so that a sealed space is formed inside the mixer. The air source assembly is started, and gas is injected into the mixer and the airbag 22 through the air inlet pipe and the air nozzle 23 respectively. At this time, the airbag 22 expands, so that the two airbags 22 and the two ends outside the mixer are closely attached respectively. Through the cooperation of the two airbags 22, the mixer is secondarily sealed to improve the accuracy of the airtightness detection of the mixer. At the same time, after an appropriate amount of gas is injected into the mixer, the air source assembly is closed, and the pressure inside the mixer is observed through the pressure gauge. If the pressure of the mixer remains unchanged, the airtightness of the mixer is good. If the pressure of the mixer drops, there is a leakage phenomenon in the mixer. At the same time, the drive assembly 40 will drive the active disk 13 and the mixer to flip, so that the staff can view the outer surface of the mixer in all directions, which is convenient for checking whether there are any leaks or defects on the outer surface.

[0053] It should be noted that since a spiral hose is assembled 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 0-180°.

[0054] Secondly, please refer to again Figure 4 , the extrusion assembly 20 further includes a heat conducting disk 24 and a heating wire 25. The heat conducting disk 24 is fixed inside the rubber pad 21, the heating wire 25 is fixed inside the heat conducting disk 24, and the heating wire and the control assembly are electrically connected through a rotary joint.

[0055] In this embodiment, when performing the airtightness 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 operate and generate heat, and transfers it to the whole of the rubber pad 21 through the heat conduction 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.

[0056] It should be noted that after the heating wire 25 works, the temperature of the heating wire 25 can be regulated through the control module. In this embodiment, the heating wire 25 can heat the rubber pad 21 to 20°C - 30°C, so that the rubber pad 21 can maintain an elastic state in a low-temperature environment. At the same time, it can also prevent the rubber pad 21 from aging due to excessive temperature.

[0057] Secondly, please refer to Figures 8 to 10 , a liquid storage cavity 16 is formed inside the base 10. An injection port is formed at the upper end of the liquid storage cavity 16, and maintenance grease is injected into the liquid storage cavity 16. A dipping groove is formed inside the base 10 and at the upper end of the liquid storage cavity 16. The oiling assembly 30 includes a liquid absorption strip 31, a sponge pad 32, and a wiping plate 33. The liquid absorption strip 31 is fixed inside the liquid storage cavity 16, and the upper end of the liquid absorption strip 31 penetrates through the liquid storage cavity 16 and extends to the outside of the liquid storage cavity 16. The sponge pad 32 is fixed inside the dipping groove, and the sponge pad 32 is in contact with the liquid absorption strip 31. The wiping plate 33 is arranged on one side of the bracket 11 through an elastic cord, and the wiping plate 33 is adapted to the dipping groove and the sponge pad 32 respectively;

[0058] Here, an observation through groove is formed on one side of the liquid storage cavity 16. An observation plate is fixed inside the observation through groove, 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;

[0059] The material of the liquid absorption strip 31 is preferably a porous material, and the liquid absorption strip 31 contains a large number of tiny pores or capillaries inside. An oil absorption felt is fixed at the lower end of the wiping plate 33.

[0060] Furthermore, when the lower end of the liquid absorption strip 31 is immersed in the maintenance grease, due to the pores or capillaries inside the liquid absorption strip 31, a capillary phenomenon can be formed, enabling the maintenance grease (such as silicone oil) inside the liquid storage cavity 16 to spontaneously rise or fall in a narrow pipe or pore, and further enabling the maintenance grease inside the liquid storage cavity 16 to be transported into the sponge pad 32;

[0061] A handle is provided on the wiping board 33 for convenient taking of the wiping board 33. When the wiping board 33 is inserted into the dipping groove on the base 10, the wiping board 33 will squeeze the sponge pad 32, extrude the maintenance grease inside it, and the oil-absorbing felt will absorb the maintenance grease, and the wiping board 33 will coat the surface of the rubber pad 21 with the grease.

[0062] In this embodiment, before the extrusion sealing, hold the wiping board 33 to dip the maintenance grease on the sponge pad 32, and coat the grease on the surface of the opposite side of the two groups of rubber pads 21 to fill the small cracks on its surface and form an oil film, improving the sealing performance and avoiding the influence of air leakage in the clamping part on the accuracy of detection.

[0063] Secondly, please refer to Figures 5 to 7 again. The driving component 40 includes a motor 41, a gear 42, a toothed ring 43 and a chain 44. The motor 41 is fixed on the top of the base 10, and the motor 41 and the control component are electrically connected through a wire. The gear 42 is fixed on the output end of the motor 41. The toothed ring 43 is fixed on the outer edge of the active disk 13, and the chain 44 is assembled on the outer sides of the gear 42 and the toothed ring 43.

[0064] It should be noted that a protective shell is fixedly connected to the position of the bracket 11 outside 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 toothed ring 43 to rotate reciprocally, and the angle range of a single rotation of the toothed ring 43 is 0 to 180°.

[0065] In this embodiment, during the detection process, when it is necessary to inspect the surface of the mixer, start the motor 41, drive the gear 42 to rotate through the motor 41, and then drive the chain 44 and the toothed ring 43 to rotate reciprocally. Drive the active disk 13 and the mixer to rotate through the toothed ring 43, and then drive the rubber pad 21 connected to the driven disk 14 and the driven disk 14 to rotate together, realizing the reciprocating rotation of the mixer so that the staff can inspect the surface of the mixer.

[0066] Embodiment Two

[0067] Please refer to Figures 10 to 13 again. This embodiment is a further optimization based on Embodiment One. Specifically:

[0068] It further includes a spray assembly 50. The spray assembly 50 includes a processing table 51. A collection tank 17 is provided inside the base 10. The processing table 51 is fixedly connected to the bottom of the base 10. An installation frame 52 is fixed to the upper end of the processing table 51. An electric guide rail 53 is assembled at the top of the installation frame 52. A spray nozzle 54 is assembled at 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. An infusion tube 57 is assembled between the liquid outlet and the input end of the water pump 56, between the output end of the water pump 56 and the spray nozzle 54.

[0069] A return port is provided at the upper end of the liquid storage tank 55, and the return port is adapted to the collection tank 17.

[0070] With the setting of the return port, the liquid sprayed on the surface of the mixer can flow back into the interior of the liquid storage tank 55 through the return port for recycling.

[0071] A filter screen is fixed inside the return port. With the setting of the filter screen, the returned liquid can be filtered so that the liquid can be recycled, improving the utilization rate of resources.

[0072] The infusion tube 57 is a spiral flexible hose.

[0073] Furthermore, the spiral flexible hose can expand and contract when the electric guide rail 53 drives the spray nozzle 54 to move, so that the infusion tube 57 can still convey liquid during the movement of the spray nozzle 54.

[0074] It should be noted that a liquid level sensor is provided inside the liquid storage tank 55, aiming to detect the water level change in the liquid storage tank 55 through the liquid level sensor, facilitating the timely addition of liquid for detection.

[0075] In this embodiment, before the airtightness detection, the mixer airtightness detection device 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 detection method of adding spray liquid is added to the airtightness detection. At this time, liquid needs to be added to the liquid storage tank 55. Subsequently, the water pump 56 operates 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 on the surface of the mixer. If there are small holes in the mixer, the liquid will be blown to form small bubbles or the liquid will be blown away, so as to visually check whether there are holes in the mixer and the positions of the holes. The sprayed liquid will flow back into the liquid storage tank 55 through the collection tank 17 on the base 10 for secondary detection, avoiding waste of resources.

[0076] It should be noted that in this embodiment, the liquid injected into the liquid storage tank 55 is soapy water. If there are gaps on the surface of the mixer and the gas inside the mixer leaks, it can cause the soapy water to form bubbles, facilitating the observation by the staff.

[0077] The working principle of the present invention is as follows: Before extrusion sealing, hold the wiping plate 33 to dip the maintenance grease on the sponge pad 32, and apply the grease on the surface of the opposite side of the two groups of rubber pads 21 to fill the small cracks on its surface and form an oil film to improve the sealing performance. Subsequently, the electric push cylinder 15 operates to push the driven disk 14 to move, and clamp the mixer between the two groups of rubber pads 21. At this time, the air nozzle 23 is externally connected to a gas source and communicated with the airbag 22, so that the airbag 22 expands and fits on the outside of the mixer to further improve the sealing effect. Subsequently, the main disk 13 is externally connected to an air pump, and gas is injected into or withdrawn from the mixer through the air inlet pipe to change the air pressure inside the mixer. By checking the change of the air pressure, it can be judged whether there is an air leakage phenomenon in the mixer. When it is necessary to perform a spray detection on the mixer, the airtightness detection device of the mixer can be installed on the processing table 51, and the collection tank 17 of the base 10 is communicated with the liquid storage tank 55 to make the airtightness detection add the detection method of spraying liquid. At this time, liquid needs to be added to the liquid storage tank 55. Subsequently, the water pump 56 operates to extract the liquid in the liquid storage tank 55 and input it into the infusion pipe 57, so that the infusion pipe 57 connected to the spray nozzle 54 sprays the liquid on the surface of the mixer. If there are small holes in the mixer, the liquid will be blown to form small bubbles or the liquid will be blown away, so as to visually check whether there are holes in the mixer and the positions of the holes. The sprayed liquid will flow back into the liquid storage tank 55 through the collection tank 17 on the base 10 for secondary detection to avoid waste of resources. At the same time, the motor 41 will drive the gear 42 to rotate, and then drive the chain 44 and the toothed ring 43 to rotate. The toothed ring 43 drives the main disk 13 and the mixer to rotate to realize the flipping of the mixer, and then the outer surface of the mixer can be completely viewed to improve the accuracy and rigor of the detection.

[0078] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
