Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to an integrated drying device and a drying method for columnar porcelain insulator glaze. Background Art

[0002] The glaze on the surface of porcelain insulators is usually controlled at 0.2-0.3mm to ensure its performance and quality. After the glaze is applied, it needs to be dried. The common drying method is to blow hot air to dry. However, due to the complex shape of the outer surface of the porcelain insulator and the inconsistent outer surface shapes of insulators of different models, the hot air blown on the surface of the porcelain insulator is not uniform when using a drying device of uniform specifications. Usually, after the outer edge of the shed on the porcelain insulator is dried, the bottom of the shed and the connection position between the porcelain insulator column and the shed have not been dried, and the drying efficiency is low. In addition, since there is a sequence in which the glaze on the surface of the porcelain insulator is dried, it is easy to cause problems such as cracking and bulging inside the glaze structure, which reduces the service life of the glaze.

[0003] To this end, we provide a columnar porcelain insulator glaze integrated drying device and drying method to solve the above problems. Summary of the invention

[0032] The present invention also discloses a method for drying the glaze of a columnar porcelain insulator in an integrated manner, comprising the device for drying the glaze of a columnar porcelain insulator in an integrated manner as described in any one of the above, and further comprising the following steps:

[0033] S1: Construct a drying space and fix the porcelain insulator column in the drying space;

[0034] Wherein, a shaping block is arranged in the drying space, and the shaping block is made of viscoelastic material, and a guide surface is formed on the surface of the shaping block after the porcelain insulator column is pressed on the shaping block;

[0036] The hot air delivery system absorbs wind from the atmosphere to heat it and then forms hot air and delivers it to the drying space. The residual hot wind in the drying space is discharged into the inner circulation space and then continues to be absorbed and heated by the hot air delivery system and then circulated and delivered to the drying space.

[0037] S3: Build a monitoring module and install a temperature sensor in the drying space. The temperature sensor monitors the temperature in the drying space and shuts down the hot air delivery system when the temperature exceeds a set threshold.

[0038] The cylindrical porcelain insulator glaze integrated drying device and drying method of the present invention have the following beneficial effects:

[0039] The invention discloses an integrated drying device and drying method for columnar porcelain insulator glaze. The hot air discharged from the air outlet is guided by the guide surface to fully and evenly act on the outer surface of the porcelain insulator column and the shed, thereby ensuring that the outer surface of the porcelain insulator column and the shed is evenly heated. The drying efficiency is high and the drying effect is good. Based on the characteristics that the shaping block can be pressed but cannot immediately restore the shape, the shaping block can be used in the integrated drying device for columnar porcelain insulator glaze to temporarily generate a corresponding shape according to the shape of the porcelain insulator column and the shed. Guide surface: when the porcelain insulator column and the shed are pressed onto the surface of the shaping block, a guide surface of corresponding shape can be formed, and then the shaping block and the porcelain insulator column are separated, and the hot air conveying system is used to convey the hot air to the surface of the guide surface for guidance and then act on the surface of the porcelain insulator column and the shed, so that the hot air can flow evenly through the surface of the porcelain insulator column and the shed, so that the glaze on the surface of the porcelain insulator column and the shed can be dried at the same time, thus avoiding low drying efficiency and quality problems such as cracking and hollowing due to deviations in the drying time period.

[0040] When the inner cylinder is moved so that the shaping block contacts the porcelain insulator column and the umbrella skirt, the bellows will be pushed and retracted into the groove to avoid it. When the porcelain insulator column and the umbrella skirt are pressed on the surface of the shaping block to form a guide surface, the inner cylinder is reset. At this time, the porcelain insulator column is located in the middle of the inner cylinder, and the porcelain insulator column is separated from the shaping block. Since the bellows loses the squeezing force of the porcelain insulator column and the umbrella skirt, the bellows is reset by the elastic recovery action of the first spring. After the bellows is reset, the air outlet can be directly opposite to the guide surface, so that the hot air transported into the inner cylinder can be just transported to the guide surface. Based on the movable setting of the bellows, it neither affects the guide surfaces of different shapes pressed and formed, nor affects the air outlet position, and can just transport the hot air to the guide surface. It is easy to use and has a simple structure.

[0041] Multiple porcelain insulator columns are arranged on multiple support seats and dried uniformly. Multiple porcelain insulator columns can be dried at one time. Position sensors are used to monitor the positions of the porcelain insulator columns. If the positions of the porcelain insulator columns are abnormal, the corresponding electromagnets above the porcelain insulator columns can be closed to separate the stainless steel plate from the electromagnets. When the outer box is raised, defective products can be quickly selected. When all qualified products are collected, the corresponding inner cylinder is opened to take out the defective porcelain insulator columns. In addition, since the inner cylinder covers the defective products, it is avoided that the qualified products nearby are also broken due to the falling of the defective products during the opening of the inner cylinder. This is more practical.

[0042] Opening the inner tube alone can avoid abnormal position of the porcelain insulator column and possible damage to the porcelain insulator column due to tipping.

[0043] The hot air blower can suck external wind into the outer box and circulate hot air in the outer box, so the amount of air sucked into the outer box can be easily controlled, so that the porcelain insulator column can be dried under a certain pressure. The drying pressure and temperature can be controlled according to the actual material, which is convenient for rapid drying.

[0044] The hot air guided from the guide surface is transported to the outer surface of the porcelain insulator column and the shed, and then is blocked by the arc baffle and discharged upward after making a circle, so that the hot air that has passed through a circle of the porcelain insulator column and the shed is just blocked by the arc baffle and discharged from the air hole, thereby preventing the hot air from staying in the outer circle of the porcelain insulator column and the shed for a long time, causing the porcelain insulator column and the shed to be wetted twice.

[0045] With reference to the following description and drawings, a specific embodiment of the present invention is disclosed in detail, indicating the manner in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereby, and within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications and equivalents.

[0061] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention.

When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0064] Please refer to the instruction manual Figures 1 to 14 The present invention provides a technical solution: a columnar porcelain insulator glaze integrated drying device, comprising:

[0065] A lower support plate 1 is a plate-like structure and is used to serve as a base support. A fixing component for fixing a porcelain insulator column 19 is arranged above the lower support plate 1. The porcelain insulator columns 19 are arranged in an array on the lower support plate 1. The fixing component includes a support seat 17. The support seat 17 is fixedly arranged on the upper surface of the lower support plate 1. A plurality of support seats 17 are arranged corresponding to the porcelain insulator columns 19. An adsorption chamber 32 is arranged inside the support seat 17. A negative pressure suction hole 33 is arranged on the upper surface of the support seat 17. The plurality of adsorption chambers 32 are connected by a connecting channel 18. The negative pressure suction hole 33 is connected to the adsorption chamber 32. A negative pressure fan is fixedly installed on the bottom surface of the lower support plate 1, and the negative pressure fan is connected to the connecting channel 18.

[0066] When the negative pressure fan is started, the porcelain insulator column 19 is adsorbed and fixed on the negative pressure suction hole 33 on the upper surface of the support seat 17 .

[0067] It should be noted that the negative pressure fan is not shown in the figure; it is a common negative pressure fixing mechanism and will not be described in detail here; and other fixing methods can be selected according to actual needs, which will not be described in detail here.

[0068] Considering that the outer surface shape of porcelain insulators is complex and the outer surface shapes of insulators of different models are inconsistent, when using a drying device of uniform specifications, the hot air blowing on the surface of the porcelain insulator is not uniform. There are the following specific situations:

[0069] Usually, after the outer edge of the shed on the porcelain insulator is dried, the bottom of the shed and the connection between the porcelain insulator column and the shed have not been dried, and the drying efficiency is low;

[0070] And because the glaze on the surface of the porcelain insulator is dried in a certain order, when a part of the glaze is dried first and then hardened, it will produce a certain degree of deformation due to thermal expansion when it continues to be dried and heated. The degree of deformation is greater than that of the glaze that has not been dried yet. When all the glaze is dried, it is easy to cause cracking and bulging inside the glaze layer structure, thereby reducing the service life of the glaze layer.

[0071] Therefore, the columnar porcelain insulator glaze integrated drying device provided in the present invention includes an inner cover part, an outer cover part and a hot air conveying system, the inner cover part can cover the porcelain insulator column 19 and form a drying space; the outer cover part can cover the inner cover part and the porcelain insulator column 19 together to form an internal circulation space, the hot air conveying system is arranged in the internal circulation space, and the hot air conveying system has two air inlet ends and one air outlet end, one of the air inlet ends is connected to the atmospheric environment, the other air inlet end is connected to the internal circulation space, the air outlet end is connected to the drying space, and the hot air discharged at the air outlet end is guided by the guide surface 42 to fully and evenly act on the outer surfaces of the porcelain insulator column 19 and the umbrella skirt 31, thereby ensuring that the outer surfaces of the porcelain insulator column 19 and the umbrella skirt 31 are evenly heated, and the drying efficiency is high and the drying effect is good.

[0072] Furthermore, a shaping block 27 is provided in the drying space. The shaping block 27 is made of a viscoelastic material. After the porcelain insulator column 19 is pressed onto the shaping block 27, a guide surface 42 is formed on the surface of the shaping block 27. Based on the characteristic that the shaping block 27 can be pressed but cannot immediately restore its shape, when the shaping block 27 is used in the columnar porcelain insulator glaze integrated drying device, a guide surface 42 of a corresponding shape can be temporarily generated according to the shape of the porcelain insulator column 19 and the shed 31. When the porcelain insulator column 19 and the shed 31 are pressed onto the shaping block, the guide surface 42 of a corresponding shape can be temporarily generated according to the shape of the porcelain insulator column 19 and the shed 31. 27 surface, a guide surface 42 of a corresponding shape can be formed, and then the shaping block 27 and the porcelain insulator column 19 are separated, and the hot air delivery system is used to deliver the hot air to the surface of the guide surface 42 for guidance and then act on the surfaces of the porcelain insulator column 19 and the umbrella skirt 31, so that the hot air can flow evenly through the surfaces of the porcelain insulator column 19 and the umbrella skirt 31, so that the glazes on the surfaces of the porcelain insulator column 19 and the umbrella skirt 31 are dried at the same time, thereby avoiding low drying efficiency and quality problems such as cracking and hollowing due to the front and rear deviations in the drying time period.

[0073] It should be noted that, while waiting for the glaze on the surface of the porcelain insulator column 19 and the shed 31 to be initially dried, the shaping block 27 will also slowly reset to facilitate recycling during the next drying.

[0074] The hot air delivery system absorbs wind from the atmosphere, heats it, and then transports it to the drying space. The waste heat in the drying space is discharged into the inner circulation space, where it is further absorbed and heated by the hot air delivery system before being circulated to the drying space, making full use of the waste heat and being more energy-efficient.

[0075] When in use, a temperature sensor 29 is also installed in the drying space. The temperature sensor 29 can monitor the temperature in the drying space. When the temperature exceeds the set threshold, the hot air delivery system is turned off to maintain a suitable temperature for drying the outer surface of the porcelain insulator column 19 and the umbrella skirt 31.

[0076] The specific implementation scheme of the present invention is as follows:

[0077] The inner cover part includes an inner cylinder 16 which is sleeved on the outside of the porcelain insulator column 19. The inner cylinder 16 is a cylindrical structure. A thermal insulation layer 30 is arranged in the wall structure layer of the inner cylinder 16, which has a certain thermal insulation effect, reduces the heat loss during drying, and can make the temperature in the inner cylinder 16 rise rapidly. The interior of the inner cylinder 16 is a drying space. A rubber sealing ring is fixedly arranged at the bottom of the inner cylinder 16, and the rubber sealing ring is movably fitted on the upper surface of the support seat 17 and sealed at the connection between the inner cylinder 16 and the support seat 17.

[0078] An air hole 21 is provided at the upper end of the inner cylinder 16, and the air hole 21 is used to discharge the hot air in the inner cylinder 16 into the inner circulation space to realize the circulation of the hot air.

[0079] An arc groove 26 is provided inside the inner cylinder 16, and a shaping block 27 is fixed in the arc groove 26. The shaping block 27 is a viscoelastic material, such as a polymer material with viscoelasticity, a composite material made of asphalt, water-soluble substances, latex and epoxy resin, etc. The material with suitable viscoelasticity can be adjusted according to actual needs. This is an existing mature technology and will not be elaborated here.

[0080] Considering that the hot air needs to be guided through the guide surface 42, a groove 34 is provided on one side of the shaping block 27, a bellows 35 is provided in the groove 34, and an air outlet 36 is provided on a side of the bellows 35 close to the middle of the shaping block 27. An air pipe 22 is fixedly provided on the outer surface of the inner cylinder 16, and the bellows 35 is communicated with the end of the air pipe 22. A first spring 28 is fixedly connected between the bottom surface of the bellows 35 and the bottom surface of the groove 34. When the inner cylinder 16 is moved so that the shaping block 27 contacts the porcelain insulator column 19 and the umbrella skirt 31, the bellows 35 will be pushed and retracted into the groove 34 to avoid it. When the porcelain insulator column 19 and the umbrella skirt 31 are pressed together on the surface of the shaping block 27 to form the guide surface 42, the bellows 35 will be pushed and retracted into the groove 34 to avoid it. , so that the inner tube 16 is reset, at this time the porcelain insulator column 19 is located in the middle of the inner tube 16, the porcelain insulator column 19 is separated from the shaping block 27, and because the bellows 35 loses the extrusion force of the porcelain insulator column 19 and the umbrella skirt 31, the bellows 35 is reset by the elastic recovery effect of the first spring 28 at this time, and when the bellows 35 is reset, the air outlet 36 can be just opposite the guide surface 42, so that the hot air transported into the inner tube 16 can be just transported to the surface of the guide surface 42; based on the movable setting of the bellows 35, it does not affect the guide surface 42 of different shapes pressed and formed, and does not affect the air outlet position, and can just transport the hot air to the surface of the guide surface 42, which is easy to use and has a simple structure.

[0081] The temperature sensor 29 is mounted on the inner wall of the inner tube 16 to facilitate real-time monitoring of the temperature in the inner tube 16 .

[0082] The outer cover part includes an outer box 2, which is simultaneously covered on the outside of multiple porcelain insulator columns 19. The inner circulation space is between the inside of the outer box 2 and the outside of the porcelain insulator columns 19. An outer box sealing ring 3 is fixedly arranged at the bottom of the outer box 2. The outer box sealing ring 3 is movably fitted on the upper surface of the lower support plate 1 and keeps the contact between the lower support plate 1 and the outer box 2 sealed.

[0083] A stainless steel plate 20 is fixedly arranged on the top surface of the inner part of the outer box 2, a connecting frame 15 is fixedly arranged on the upper surface of the inner cylinder 16, and an electromagnet 14 is connected to the upper end of the connecting frame 15, and the electromagnet 14 is adsorbed and fixed in the stainless steel plate 20; the outer box 2 can be raised and lowered and moved horizontally; when the outer box 2 moves horizontally, it drives multiple inner cylinders 16 to move simultaneously and fits the shaping block 27 inside the inner cylinder 16 onto the umbrella skirt 31 of the outer ring of the porcelain insulator column 19, and the umbrella skirt 31 presses the shaping block 27 to form a guide surface 42 on the surface of the shaping block 27; when the outer box 2 descends, it drives the inner cylinder 16 to be conveniently covered on the outside of the porcelain insulator column 19 to construct a drying space and an internal circulation space, and when the outer box 2 rises, it drives the inner cylinder 16 to rise, and the porcelain insulator column 19 can be exposed to the surface of the lower support plate 1, which is convenient for taking and placing.

[0084] During actual processing, multiple porcelain insulator columns 19 are arranged on multiple support seats 17 and dried uniformly. Multiple porcelain insulator columns 19 can be dried at one time. Multiple porcelain insulator columns 19 are adsorbed and fixed on the upper surface of the support seat 17 by the same negative pressure fan, which is convenient for fixation. However, during the drying process, the porcelain insulator columns 19 are blown by hot air, and sometimes there is a risk of accidental tipping over due to unstable fixation. When the porcelain insulator columns 19 tip over, the undried glaze is easily deformed, and the drying quality is difficult to guarantee. The products are defective and need to be discarded.

[0085] Therefore, a position sensor is also installed on the inner wall of the inner cylinder 16, and the position sensor is used to monitor the position of the porcelain insulator column 19. If the position of the porcelain insulator column 19 is abnormal, such as tipping over, the corresponding electromagnet 14 above the porcelain insulator column 19 can be closed to separate the stainless steel plate 20 from the electromagnet 14. When the outer box 2 is raised, the defective products can be quickly selected. When all the qualified products are collected, the corresponding inner cylinder 16 is opened and the defective porcelain insulator column 19 can be taken out. Since the inner cylinder 16 covers the defective products, it is avoided that the qualified products nearby are also tipped over and broken due to the tipping over of the defective products during the opening of the inner cylinder 16, which is more practical.

[0086] When in use, as long as the position sensor monitors the position of the porcelain insulator column 19 and finds an abnormality, it will feed back this information data to the controller, and the controller controls the electromagnet 14 to close, and the magnetism on the electromagnet 14 disappears. When the outer box 2 rises, the corresponding inner cylinder 16 is still covered on the outside of the porcelain insulator column 19; when the inner cylinder 16 is subsequently opened, the porcelain insulator column 19 can also be taken out separately. Some porcelain insulator columns 19 with position displacement are also qualified products. At this time, the staff can prevent the porcelain insulator column 19 from tipping over in time. Therefore, opening the inner cylinder 16 alone can avoid abnormal position of the porcelain insulator column 19 and possible damage to the porcelain insulator column 19 due to tipping over.

[0087] It should be noted that the controller is a common existing technology and will not be described in detail here.

[0088] The hot air delivery system is connected to the air pipe 22 and delivers the hot air to the surface of the guide surface 42 through the air pipe 22, the bellows 35, and the air outlet 36 in sequence. The hot air is guided by the guide surface 42 and acts evenly on the outer surface of the porcelain insulator column 19 and the umbrella skirt 31.

[0089] The hot air delivery system includes a hot air blower 23, which is fixedly mounted on the top of the outer box 2. The hot air blower 23 is provided with a first pipe 11, a second pipe 24 and a third pipe 25. The first pipe 11 is connected to the outside of the outer box 2, the second pipe 24 and the third pipe 25 are both arranged inside the outer box 2, and the third pipe 25 is connected to the air pipe 22 through a hose. When the hot air blower 23 is started during the initial drying process, the external air is sucked into the hot air blower 23 and discharged into the third pipe 25 after being heated. The hot air passes through the third pipe 25, the air pipe 22, the third pipe 25, the arc groove 26 and the guide surface 42 in sequence and then acts on the outer surface of the porcelain insulator column 19 and the umbrella skirt 31. When there is a certain pressure inside the outer box 2, the second pipe 24 is allowed to inlet air and the third pipe 25 is allowed to outlet air, so that the hot air internal circulation operation is completed, and the waste heat is fully saved.

[0090] Furthermore, solenoid valves are provided in the first pipe 11, the second pipe 24 and the third pipe 25 to facilitate the on-off control of the first pipe 11, the second pipe 24 and the third pipe 25. The hot air blower 23 can suck external wind into the outer box 2, and the hot air can circulate in the outer box 2, so that the amount of air sucked into the outer box 2 can be conveniently controlled, so that the porcelain insulator column 19 can be dried under a certain pressure. The drying pressure and temperature are controlled according to the actual material, which is convenient for rapid drying.

[0091] Among them, a moving groove 38 is provided on the inner wall of the inner cylinder 16, a sliding plate 40 is slidably provided in the moving groove 38, a second spring 41 is fixedly connected to one side of the sliding plate 40, and an arc plate 39 is fixedly connected to the other side, the end of the second spring 41 away from the sliding plate 40 is fixedly connected to the inner wall of the side of the moving groove 38, the arc plate 39 is movably fitted on the inner wall of the inner cylinder 16, and an arc baffle 37 is integrally provided at the end of the arc plate 39 away from the sliding plate 40, and the arc baffle 37 is a round shell structure with an opening facing the sliding plate 40; the hot air guided from the surface of the guide surface 42 is transported to the porcelain insulator column 19 and the outer surface of the umbrella skirt 31 After going around the surface once, it is blocked by the arc baffle 37 and discharged upward, so that the hot air passing through the porcelain insulator column 19 and the umbrella skirt 31 once can be discharged from the air hole 21 just after passing through the obstruction of the arc baffle 37, so as to avoid the hot air staying in the outer circle of the porcelain insulator column 19 and the umbrella skirt 31 for a long time so that the porcelain insulator column 19 and the umbrella skirt 31 are wetted for a second time. When the hot air is discharged from the air hole 21 for reuse, a dehumidification filtering mechanism for filtering and removing dust and water vapor in the air, such as a sponge block, can be provided at the outlet to ensure that the hot air flowing through the outer circle of the porcelain insulator column 19 and the umbrella skirt 31 always remains dry and clean.

[0092] Furthermore, a dehumidification filter mechanism may be connected to the end of the first pipe 11, and the dehumidification filter mechanism is used to filter and remove dust and water vapor in the air, and can be set according to actual needs.

[0093] Since the sliding plate 40 at the end of the arc plate 39 is connected to the moving groove 38 through the second spring 41, when the hot air blows to the arc baffle 37, it can be blocked by the arc baffle 37 and the arc plate 39 can move along the inner wall of the inner cylinder 16 to achieve buffering and unloading, avoiding excessive wind force and directly merging with the fresh air at the air outlet 36;

[0094] The arc plate 39 and the shaping block 27 are arranged adjacent to each other, and one end of the arc plate 39 having the arc baffle 37 is close to the shaping block 27; when the arc plate 39 moves along the inner wall of the inner tube 16 to the middle of the shaping block 27, an air outlet gap 44 is formed between the end of the arc plate 39 away from the sliding plate 40 and the edge of the guide surface 42, and an air guide gap 43 is formed between the arc plate 39 and the inner wall of the guide surface 42, which fully avoids the fresh air at the air outlet 36 from merging with the exhausted air that has blown over the surface of the porcelain insulator column 19 and the umbrella skirt 31. The air guide gap 43 can further form a guiding space for the fresh air, and the air outlet gap 44 reduces the outlet area, making it convenient for the hot air to act more concentratedly on the outer surface of the porcelain insulator column 19 and the umbrella skirt 31.

[0095] In the present invention, the lifting and horizontal movement of the outer box 2 is achieved by setting a driving component, which includes: a first electric cylinder 8 for driving the outer box 2 to lift and a second electric cylinder 13 for driving the outer box 2 to move horizontally.

[0096] The first electric cylinder 8 is distributed vertically, and the upper end of the first electric cylinder 8 is fixedly connected with a top support plate 9, and the top support plate 9 is fixed to the top support by bolts; wherein, a rectangular frame 4 is arranged above the outer box 2, and two sliding beams 5 are fixedly arranged in the rectangular frame 4, and a middle connecting plate 10 is fixedly connected in the middle position between the two sliding beams 5, and the lower end of the first electric cylinder 8 is fixedly installed on the upper surface of the middle connecting plate 10; when the first electric cylinder 8 is started, the outer box 2 and the rectangular frame 4 can be driven to rise and fall.

[0097] One end of the second electric cylinder 13 is fixedly connected to the inner wall of one side of the rectangular frame 4, and the other end of the second electric cylinder 13 is fixedly connected to the connecting rod 12; a plurality of brackets 6 are fixedly arranged on the upper surface of the outer box 2, and a sliding sleeve 7 is fixedly connected to the upper end of the bracket 6, and the sliding sleeve 7 is slidingly arranged on the sliding beam 5, and the connecting rod 12 is fixedly connected between the corresponding two sliding sleeves 7; when the second electric cylinder 13 is started, it can push the connecting rod 12 and the outer box 2 to move along the length direction of the sliding beam 5.
