Description
Technical Field
[0001] This invention relates to the field of drying equipment technology, and in particular to a special device for drying spark plugs and silica gel for internal combustion engines. Background Technology
[0002] During the operation of the gas-fired internal combustion engine unit, it was found that the service life of the spark plug is generally around 3000 hours. After 2000 hours of use, the ignition capability will drop significantly, making it difficult to start the unit when cold. At this time, the spark plug must be removed and dried to remove the moisture from the surface of the spark plug ignition head before starting. In addition, dehydrating silica gel should be installed in the pressure monitoring device of the gas intake active valve and other parts. After the silica gel absorbs water, it needs to be dried and regenerated regularly.
[0003] Currently, the drying methods used are mostly direct flame heating or electric furnace heating. These two methods are not very efficient and are time-consuming and labor-intensive. Silica gel drying also involves disassembling the gel and sending it to the laboratory for drying in an oven or electric furnace, which is quite troublesome to operate on-site.
[0004] Research revealed the absence of dedicated drying devices for spark plugs and silica gel for internal combustion engine units on the market. To reduce labor intensity and improve unit maintenance efficiency, a dedicated drying device for internal combustion engine spark plugs has been invented and manufactured. Therefore, those skilled in the art provide a dedicated device for drying internal combustion engine spark plugs and silica gel to solve the problems mentioned in the background section. Summary of the Invention
[0005] The purpose of this invention is to address the problems existing in the background art by proposing a special device for drying spark plugs and silica gel for internal combustion engines.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a special device for drying spark plugs and silica gel for internal combustion engines, comprising a housing, a top cover, a bottom box, and side cylinders. The bottom box is located at the lower end of the housing, and the top cover is located at the upper end of the housing. A heating chamber is located inside the lower end of the housing. A support plate connected to the inner wall of the housing is located at the upper end of the heating chamber. A placement plate connected to the inner wall of the housing is located above the support plate. The placement plate has equidistantly distributed placement holes, into which spark plugs are inserted. A reflector is located on the lower inner wall of the heating chamber, and an infrared lamp is located inside the heating chamber.

A first flow guide shroud is provided at one end of the partition, penetrating the first end of the housing. A discharge pipe is provided inside the first flow guide shroud, and a regulating valve is provided inside the discharge pipe.
[0007] Preferably, the shell is made of heat-resistant materials such as ceramics to ensure minimal deformation and maintain high mechanical strength under high temperature conditions.

The outer wall of the support shaft is sleeved with a side block one connected to the rear end of the top cover. A torsion spring is sleeved on the outer side of the support shaft, with its two ends connected to the side blocks one and two respectively. A connecting block is provided between the shell and the top cover and fixed by bolt thread insertion.
[0008] Preferably, the inner wall of the heating chamber is provided with a heat preservation device and a heating device. The heating chamber is a relatively closed space formed by the inner heat preservation layer of the shell, the heating device and the support plate. The steam generated in the heating chamber can be released through the conveying pipe.
[0009] Preferably, the insulation layer of the heat preservation device is composed of silicate cotton material with high thermal resistance and heat resistance coefficient, which is used to reduce the shell temperature, ensure safe use, isolate heat, and improve thermal efficiency. Slides are provided on both sides of the inner wall of the heating chamber, and guide grooves are opened inside the slides. A slider connected to the placement frame is installed inside the rear end of the guide groove.
[0010] Preferably, a temperature control rotating shaft is provided inside the housing, and the temperature control device consists of a sensor and a temperature control main board. The sensor is used to measure the temperature of the heating chamber and feed it back to the temperature control main board. The temperature control main board controls the working state of the heating device based on the set logic, thereby realizing constant or variable temperature control of the heating chamber.
[0011] Preferably, the housing side plate is provided with a magnetic suction device to help the housing hang on the side plate of the internal combustion engine container, preventing the device filled with spark plugs from tipping over during use. The front end of the housing has an opening for placing silicone, and the front end of the silicone placement opening is provided with a front cover.
[0012] Preferably, the heating chamber has two modes: spark plug drying and silica gel drying. In spark plug drying mode, the spark plug is inserted through the placement hole inside the placement plate, and the energy of the heating device below is released onto the spark plug head. In silica gel drying mode, a thin stainless steel placement frame is inserted above the heating device, and the silica gel absorbs heat from the bottom in the drawer and then dehydrates.
[0013] Preferably, a mounting shaft is rotatably mounted inside the heating chamber, and a blade is rotatably mounted inside the heating chamber and located below the placement frame on the outer wall of the upper end of the mounting shaft.

An ultrasonic cleaning device is provided inside the lower end of the housing.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the silicone is placed on a frame and heated by a heating device. After the moisture is dried, it enters the side cylinder through a first conveying pipe and is then conveyed to the outside through a second conveying pipe, thus achieving the drying of the silicone. During spark plug drying, the valve inside the second delivery pipe is closed, and the first delivery pipe is opened. The heat inside the heating chamber is guided into the support plate through the second guide shroud and comes into contact with the spark plug head. The steam is gathered to the outside through the first guide shroud. The guide device ensures that the spark plug head is heated evenly. During the drying process, the first and second blades rotate to help the flow of hot air. At the same time, the first and second blades are driven by the same motor, reducing energy consumption. This device integrates the functions of internal combustion engine spark plug drying and silica gel drying, making it a convenient special drying device for use in internal combustion engine maintenance sites. It solves the problems of low efficiency and insufficient safety of current electric furnace drying. Attached Figure Description

[0019] 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.
[0020] Please see Figures 1 to 9 The present invention provides three embodiments: Example 1: A special device for drying spark plugs and silica gel for internal combustion engines includes a housing 1, a top cover 2, a bottom box 9, and a side cylinder 12. The bottom box 9 is located at the lower end of the housing 1, and the top cover 2 is located at the upper end of the housing 1. A heating chamber 22 is located inside the lower end of the housing 1. A support plate 8 connected to the inner wall of the housing 1 is located at the upper end of the heating chamber 22. A placement plate 3 connected to the inner wall of the housing 1 is located above the support plate 8. The placement plate 3 has equidistantly distributed placement holes 5, and spark plugs 4 are inserted into the placement holes 5. A reflector 27 is located on the inner wall of the lower end of the heating chamber 22. An infrared lamp 28 is located inside the heating chamber 22. A placement frame 39 is located inside the heating chamber 22. The placement frame 39 is filled with silicone and has equally spaced through holes 40. The heating chamber 22 is provided with a flow guide 26 at one end and a conveying pipe 25 at the other end. A side cylinder 12 is provided at the upper end of the conveying pipe 25 and a second conveying pipe 23 is connected to the upper end of the side cylinder 12. A second flow guide 19 is provided at one end of the conveying pipe 23, penetrating the upper interior of the housing 1. A partition 20 is provided on the inner wall of the second flow guide 19 to separate the spark plugs 4 in the same row. A first flow guide 13 is provided at one end of the partition 20, penetrating one end of the housing 1. A discharge pipe 21 is provided inside the first flow guide 13 and a regulating valve is provided inside the discharge pipe 21. In this embodiment, the spark plug 4 drying mode is as follows: the spark plug 4 to be dried is inserted into the placement plate 3 through the placement hole 5, and the top cover 2 is tightened to seal it; the infrared lamp 28 is turned on, the heating chamber 22 generates heat, the reflector 27 reflects and concentrates heat to improve thermal efficiency, the hot air flows upward through the support plate 8, and is evenly surrounded around the head of the spark plug 4 by the guidance of the second guide shroud 19 and the partition 20; the steam generated during drying is driven by the hot air flow, and is gathered by the partition 20 to the first guide shroud 13, and discharged through the discharge pipe 21. The flow rate is controlled by adjusting the regulating valve to achieve precise drying of the spark plug 4.
[0021] Silica gel drying mode: Remove spark plug 4, place the placement frame 39 containing the silica gel to be dried into the heating chamber 22, close the regulating valve of the discharge pipe 21, and open the control valves 24 of the first conveying pipe 25 and the second conveying pipe 23; the infrared lamp 28 heats the silica gel, which fully absorbs heat through the through hole 40 of the placement frame 39, and the moisture evaporates to form steam, which enters the side cylinder 12 through the guide hood 26 and the first conveying pipe 25, and then exits the device through the second conveying pipe 23 to complete the silica gel dehydration and drying; Traditional devices can only dry spark plugs 4 or silica gel individually, requiring two sets of equipment, which is space-consuming and costly. This device integrates dual modes, with one set of equipment meeting both needs, adapting to the diverse drying requirements of internal combustion engine maintenance sites. Traditional electric furnace drying lacks directional airflow, resulting in dispersed heat, uneven heating of the spark plug head, and prolonged drying time. This device uses reflector 27 to concentrate heat, guide hood 2 19, and baffle 20 to directionally guide the hot airflow precisely onto the spark plug head, improving drying uniformity and efficiency. Traditional silica gel drying lacks a dedicated placement structure, leading to uneven heating of the silica gel and incomplete dehydration. This device's placement frame 3... 9. With through holes 40, the silicone is ensured to come into full contact with heat for thorough drying. In traditional drying, steam diffuses randomly, polluting the environment and posing safety hazards. This device achieves orderly and controllable steam discharge through a complete flow guide and regulating valve, ensuring a clean and safe operating environment. In traditional drying, spark plug 4 is prone to tipping or poor contact. In this device, the placement hole 5 of the placement plate 3 is precisely inserted and positioned to prevent the spark plug 4 from shifting during the drying process, ensuring the drying effect. Traditional heating lacks heat preservation and heat concentration structures, making heat easy to dissipate. In this device, the heating chamber 22 is relatively sealed, and with the reflector 27, heat is concentrated, reducing heat waste and improving heat utilization efficiency. Integrating spark plug 4 drying and silica gel drying functions, this device eliminates the need for equipment replacement, significantly reducing maintenance costs and space requirements. It caters to the convenience needs of on-site maintenance of internal combustion engines. The reflector 27's heat-concentrating and directional flow structure ensures precise heat application to the drying object, allowing both the spark plug 4 head and silica gel to be heated from all directions, shortening drying time and improving drying quality. Switching between the two modes requires no complex disassembly; only the placement object and regulating valve need to be changed. The discharge pipe 21's regulating valve allows for flexible control of steam flow rate, adapting to different drying needs. The ceramic shell 1 is high-temperature resistant and has minimal deformation, while the placement hole 5 precisely positions the drying object. The overall structure is compact, suitable for installation and use in maintenance scenarios such as internal combustion engine containers. Orderly steam discharge avoids pollution and safety hazards, while the relatively enclosed heating chamber 22 reduces heat leakage, ensuring operator safety and meeting energy-saving requirements. Example 2:
[0022] The shell 1 is made of heat-resistant materials such as ceramics to ensure that the deformation is small and the mechanical strength is maintained under high temperature conditions. The top cover 2 has a symmetrically distributed side block 2 17 at one end. A support shaft 15 is rotatably installed inside the side block 2 17. The outer wall of the support shaft 15 is sleeved with a side block 14 connected to the rear end of the top cover 2. A torsion spring 16 is sleeved on the outside of the support shaft 15, with its two ends connected to the side block 14 and the side block 2 17 respectively. A connecting block 43 is provided between the shell 1 and the top cover 2 by bolt thread insertion. The inner wall of the heating chamber 22 is provided with a heat preservation device 18 and a heating device. The heating chamber 22 is a relatively closed space formed by the heat preservation layer inside the shell 1, the heating device and the support plate 8. The steam generated in the heating chamber 22 can be released through the conveying pipe 25. The insulation layer of the heat preservation device 18 is composed of silicate cotton material with high thermal resistance and heat resistance coefficient. It is used to reduce the temperature of the shell 1, ensure safe use, isolate heat, and improve thermal efficiency. The inner walls on both sides of the heating chamber 22 are provided with slides 38. The slides 38 are provided with guide grooves 41. The rear end of the guide grooves 41 is equipped with sliders 42 connected to the placement frame 39. The housing 1 is equipped with a temperature control rotating shaft 11. The temperature control device consists of a sensor and a temperature control main board. The sensor is used to measure the temperature of the heating chamber 22 and feed it back to the temperature control main board. The temperature control main board controls the working state of the heating device based on the set logic, thereby realizing constant or variable temperature control of the heating chamber 22. The side panel of the housing 1 is equipped with a magnetic suction device to help the housing 1 hang on the side panel of the internal combustion engine container to prevent the device filled with spark plug 4 from tipping over during use. The front end of the housing 1 has a silicone placement port 7, and the front end of the silicone placement port 7 is equipped with a front cover 6. The heating chamber 22 has two modes: spark plug 4 drying and silica gel drying. In the spark plug 4 drying mode, the spark plug 4 is inserted through the placement hole 5 inside the placement plate 3, and the energy of the heating device below is released to the spark plug 4 head. In the silica gel drying mode, the thin stainless steel placement frame 39 is inserted above the heating device, and the silica gel absorbs the heat from the bottom in the drawer and then dehydrates. In this embodiment, the spark plug 4 drying mode is as follows: the housing 1 is hung on the side plate of the internal combustion engine container by a magnetic suction device to prevent tipping; the top cover 2 is opened, and the torsion spring 16 assists in opening it with ease, and the spark plug 4 is inserted into the placement hole 5 of the placement plate 3, and the bolt fixing docking block 43 seals the top cover 2; the heating device is started, and the temperature control sensor monitors the temperature of the heating chamber 22 in real time and feeds it back to the temperature control main board to accurately control the working status of the infrared lamp 28 to maintain a constant temperature; the heat insulation layer reduces heat loss, the reflector 27 concentrates heat, and the hot air flows around the head of the spark plug 4 through the second guide shroud 19 and the partition 20, and the steam is discharged through the first guide shroud 13 and the exhaust pipe 21 to achieve efficient and uniform drying.
[0023] Silica gel drying mode: Open the front cover 6, pull out the placement frame 39 through the guide groove 41 of the slide 38, the slider 42 slides smoothly, put in the silica gel to be dried and push it back into the heating chamber 22; close the regulating valve of the discharge pipe 21 and open the control valve 24 of the conveying pipe 25; the temperature control device controls the heating intensity, the silica gel fully absorbs heat and dehydrates through the through hole 40 of the placement frame 39, and the steam is discharged through the guide hood 26 and the conveying pipe 25; after drying is completed, pull out the placement frame 39 to take out the silica gel, without disassembling other parts.
[0024] Example 1 does not specify the material of the shell 1, which is prone to deformation at high temperatures, affecting the seal. The ceramic shell 1 is resistant to high temperatures and has high mechanical strength, making it suitable for the high-temperature environment during drying and ensuring that it will not deform during long-term use. Example 1 lacks a heat insulation structure, which makes it easy for heat to leak out. The silicate cotton insulation layer isolates heat, which not only improves thermal efficiency and shortens drying time, but also reduces the temperature of the outer wall of the shell 1, ensuring operational safety. Example 1 does not have a temperature control function, and excessive temperature can easily damage the spark plug 4 or the silicone. The temperature control device achieves constant temperature through sensor monitoring and mainboard regulation. Temperature control prevents over-drying or incomplete drying. In Implementation 1, the placement frame 39 is cumbersome to install and disassemble. The sliding cooperation between the slide block 38 and the slider 42 allows the placement frame 39 to be pulled out smoothly. With the silicone placement port 7 and the front cover 6, the silicone can be replaced without disassembling the whole device, making operation convenient. Implementation 1 lacks a stable structure and is prone to tipping over when moved during operation and maintenance. The magnetic suction device can be hung on the side panel of the container to improve the stability of the device and adapt to the use scenario of narrow site and frequent movement. The sealing and opening and closing of the top cover 2 in Implementation 1 is not convenient enough. The torsion spring 16 assists in opening with less effort. The bolt fixing of the connecting block 43 ensures the seal, prevents heat leakage and the entry of external impurities, and improves the cleanliness of the drying environment. The ceramic shell 1 is high-temperature resistant, the insulation layer is heat-resistant and energy-saving, and the magnetic suction device prevents tipping. Multiple protections adapt to the complex environment of internal combustion engine maintenance sites, eliminating safety hazards such as high-temperature deformation and tipping. The temperature control device achieves precise temperature regulation, avoiding over-drying or incomplete drying, ensuring that the spark plug 4 performance is not damaged and that the silica gel adsorption effect is stable after drying, improving the reliability of experiments and maintenance. The torsion spring 16 assists in opening and closing the top cover 2, the sliding placement frame 39, and the dedicated placement port, simplifying the process of picking up, placing, and replacing. The bolt fixing docking block 43 ensures sealing and facilitates disassembly and maintenance, reducing the labor intensity of maintenance personnel. The insulation layer reduces heat waste, and together with the reflector 27, it concentrates heat, significantly improving thermal efficiency. The magnetic hanging design adapts to on-site installation requirements. The combination of the ceramic shell 1 and the insulation layer allows the device to work stably in different temperature environments. The ceramic material, silicate cotton insulation layer, and sliding structure are all wear-resistant and corrosion-resistant. The torsion spring 16 and bolt connection are stable and not prone to failure after long-term high-frequency use, adapting to the high-frequency drying requirements of internal combustion engine maintenance sites. Example 3:
[0025] The heating chamber 22 is rotatably mounted with a mounting shaft 32. The upper outer wall of the mounting shaft 32 is provided with a blade 33 rotatably mounted inside the heating chamber 22 and located below the placement frame 39. The conveying pipe 25 and the conveying pipe 23 are both provided with control valves 24. The bottom box 9 is equipped with a motor 10. The output end of the motor 10 is equipped with a rotating shaft 11. The outer wall of the rotating shaft 11 is fitted with a bevel gear 30 and a bevel gear 34. The lower end of the mounting shaft 32 is rotatably mounted inside the bottom box 9 and the outer wall is fitted with a bevel gear 31 that meshes with the bevel gear 30. Both the base box 9 and the side cylinder 12 have mounting shafts 36 rotatably installed inside. One end of the mounting shaft 36 inside the side cylinder 12 has blades 37 arranged in a circular array. The outer wall of the rotating shaft 11 inside the base box 9 is fitted with a bevel gear 35 that meshes with a bevel gear 34. An ultrasonic cleaning device 29 is installed inside the lower end of the housing 1. In this embodiment, the ultrasonic cleaning device 29 is first activated to clean and descale the dirty spark plug 4. After cleaning, the spark plug 4 is inserted into the placement hole 5 of the placement plate 3, the top cover 2 is closed, and the housing 1 is fixed by the magnetic suction device. The spark plug 4 drying mode is switched, the control valve 24 of the second conveying pipe 23 is closed, the control valve 24 of the first conveying pipe 25 is opened, the motor 10 and the infrared lamp 28 are started, the motor 10 drives the bevel gear set through the rotating shaft 11, and synchronously drives the first blade 33 and the second blade 37 to rotate. The first blade 33 stirs the hot airflow in the heating chamber 22, and with the reflector 27, the guide hood 2 19 and the partition 20, the heat is evenly wrapped around the head of the spark plug 4 to accelerate the evaporation of residual moisture. The second blade 37 accelerates the airflow in the side cylinder 12, so that the steam generated by drying is quickly discharged through the guide hood 26 and the first conveying pipe 25 to achieve drying without residue after cleaning.
[0026] Remove spark plug 4, push the silicone rubber container 39 into the heating chamber 22, close the control valve 24 of the first delivery pipe 25, and open the control valve 24 of the second delivery pipe 23; the motor 10 drives the first blade 33 to rotate, enhancing the hot air circulation in the heating chamber 22. The silicone rubber fully absorbs heat and dehydrates through the through hole 40 of the container 39. The second blade 37 drives the airflow in the side cylinder 12, and the steam is quickly discharged through the second delivery pipe 23, improving the drying efficiency of the silicone rubber. The temperature control device adjusts the temperature in real time to prevent the silicone rubber from overheating and failing. Example 2 addresses the problem of passive hot airflow and limited drying efficiency. Example 2 relies on natural convection, resulting in insufficient hot airflow circulation and local temperature differences. The first blade 33 actively stirs the airflow in the heating chamber 22, and the second blade 37 accelerates steam discharge, allowing for more complete heat exchange and significantly improving drying efficiency. Traditionally, spark plug 4 needs to be cleaned separately before being transferred for drying, which is prone to secondary contamination and cumbersome. This device integrates ultrasonic cleaning and drying. The device features a dry function, forming a closed loop of cleaning and drying. It eliminates the need for transfer, avoids contamination, and saves time. In Example 2, the airflow is controlled by a single regulating valve, which can easily cause airflow turbulence when switching modes. The addition of a delivery pipe control valve 24, which is linked with the blades, enables precise switching of the airflow path between the two modes, preventing crossflow from affecting the drying effect. Example 2 lacks a linkage drive structure, and the independent operation of multiple components consumes a lot of energy. This device uses a bevel gear set to enable the same motor 10 to synchronously drive the two blades, reducing the number of power sources and energy consumption, and adapting to the energy-saving requirements on site. After traditional cleaning, the spark plug 4 surface is prone to residual moisture, and natural drying takes a long time. Ultrasonic cleaning and active airflow drying linkage quickly remove residual moisture, preventing moisture from causing spark plug 4 to rust or ignition failure. In Example 2, when the silica gel is drying, the steam emission depends on the thermal pressure difference and is slow. Blade 2 37 accelerates the airflow of the side cylinder 12, shortens the steam residence time, and makes the silica gel dehydrate more thoroughly. Integrating ultrasonic cleaning, spark plug drying, and silica gel drying, this device forms a closed-loop cleaning and drying system, requiring no additional equipment. It is suitable for one-stop maintenance needs in internal combustion engine operation and maintenance sites. The active airflow circulation structure ensures more thorough heat exchange, leaving no residue after cleaning and drying. Silica gel is dehydrated more completely, and spark plugs are heated more evenly, significantly shortening drying time and ensuring component performance after drying. The same motor 10 drives dual blades, reducing energy consumption. Magnetic fixation and convenient mode switching make it suitable for confined spaces and high-frequency use in internal combustion engine containers, offering efficient and worry-free operation. The control valve 24, linked with the blades, enables precise airflow path switching. A temperature control device prevents overheating damage, and steam is quickly and orderly discharged, ensuring both drying effectiveness and eliminating safety hazards. The ultrasonic cleaning device 29 is suitable for the maintenance needs of dirty spark plugs. The bevel gear transmission structure is stable and wear-resistant. The ceramic shell 1 and silicate cotton insulation layer are high-temperature resistant, have high thermal efficiency, and are not prone to failure with long-term use.
