Technical Field

[0001] The present invention relates to a main body of an impregnating tank, and in particular to a main body of an impregnating tank with a heat preservation structure. The present invention also relates to a heat preservation process, and in particular to a heat preservation process for a main body of an impregnating tank with a heat preservation structure, belonging to the technical field of impregnating tanks. Background Art

[0002] An impregnating tank is a device used to immerse a glue solution into materials or workpieces, mainly for sealing, strengthening or manufacturing composite materials. Its working principle usually includes vacuum treatment, pressure control and temperature adjustment to ensure that the glue solution fully penetrates and fills pores or surfaces.

[0003] In the prior art, such as the vacuum impregnating tank and optical fiber ring preparation equipment disclosed in the application number 202320273457.4, in order to solve the problems that the air in the tank is heated slowly and the temperature in the tank area is stratified, and the poor temperature uniformity leads to poor heating effect of the glue raw material, reducing the impregnating efficiency and qualification rate, the heating mechanism is arranged on the outer side wall of the tank body of the vacuum impregnating tank and extends along the axial direction of the tank body, so that in the axial direction of the tank body, the heating mechanism can heat the whole vacuum impregnating tank, improving the heating synchronization in the axial direction, thereby avoiding temperature stratification in the impregnating cavity after heating, effectively improving the temperature uniformity in the axial direction of the impregnating cavity along the tank body, and improving the impregnating qualification rate.

[0004] The prior art similar to the above application still has deficiencies:

[0005] There is a lack of a heat preservation structure on the impregnating tank, which is easily affected by the external environment during use, increasing heat consumption and being energy - inefficient. Moreover, during the sealing process of the tank body, not only an electric telescopic rod is required to control the sealing cover to flip and close, but also a pressing and fixing operation is required, making it inconvenient to use.

[0006] Therefore, a main body of an impregnating tank with a heat preservation structure and a heat preservation process are designed to optimize the above problems. Summary of the Invention

[0007] The main object of the present invention is to provide a dipping tank body with a heat preservation structure. The dipping tank body composed of an inner tank body, an outer tank body, an outer connecting cylinder, an inner connecting cylinder, an inner cover plate, and an outer cover plate can have a double-layer structure after being sealed. Through the air suction pipe, it is communicated between the inside of the dipping tank body and the internal gap. During the process of vacuum pumping, a double-vacuum environment can be formed, effectively avoiding heat loss and having a better heat preservation effect. The capping mechanism composed of a fixed arm, a spline shaft, a shaft hole, a limiting block, a second spring, a bracket, an electric telescopic rod, a sleeve, a vertical guide groove, an arc guide groove, and a guide post between the outer tank body and the outer cover plate is used. During the process of opening the cover plate, through a single electric telescopic rod, not only can the vertical movement of the cover plate be controlled, but also the horizontal rotation of the cover plate can be controlled, so that the tank body can be completely opened for loading and unloading materials, and the control is more convenient and the practicability is higher. Through the uniformly arranged L-shaped positioning grooves on the outer side of the outer connecting cylinder, and then cooperating with the L-shaped hooks on the outer cover, as well as the positioning support rod, bevel gear, bevel gear ring, transmission gear, and rack composed of a rotating assembly, after the cover plate is attached to the top of the connecting cylinder, as the electric telescopic rod continues to move down, the rotation of the connecting cylinder can be controlled, and the L-shaped hook is stuck inside the L-shaped positioning groove to complete the sealing and fixing of the cover plate, which is simple and convenient to use.

[0018] The present invention also provides an impregnating tank body heat preservation process with a heat preservation structure, comprising the following steps:

[0019] Step 1: When the outer cover plate is fully opened, it is located on the side of the outer tank body. At this time, the guide post is located at the top end of the arc-shaped guide groove. When closing, start the electric telescopic rod to control the spline shaft to drive the outer cover plate to move downward. At the same time, the guide post slides downward inside the arc-shaped guide groove. The spline shaft will rotate to control the outer cover plate to move toward the top of the outer connecting cylinder. When the guide post enters the inside of the vertical guide groove, the outer cover plate is located directly above the outer connecting cylinder at this time. Continue to control the downward movement of the spline shaft until the bottoms of the outer cover plate and the inner cover plate are in contact with the tops of the outer connecting cylinder and the inner connecting cylinder.

[0020] Step 2: When the outer cover plate moves vertically downward, the L-shaped hook vertically enters the inside of the L-shaped positioning groove. When the bottom end of the L-shaped hook is in contact with the top of the pressing plate and presses the pressing plate down by a distance equal to the thickness of the bottom end of the L-shaped hook, at this time, the bottoms of the outer cover plate and the inner cover plate are in contact with the tops of the outer connecting cylinder and the inner connecting cylinder, but the guide post does not enter the bottom end of the vertical guide groove. At the same time, the rack is engaged with the transmission gear at this time.

[0021] Step 3: When the electric telescopic rod continues to control the spline shaft and the rack to move downward, at this time, the limiting block will squeeze the fixed arm, and the second spring will be compressed, improving the fitting effect between the bottoms of the outer cover plate and the inner cover plate and the tops of the outer connecting cylinder and the inner connecting cylinder. At the same time, the rack will drive the transmission gear to rotate, the transmission gear controls the bevel gear to rotate, and the bevel gear controls the outer connecting cylinder to rotate, rotating the bottom end of the L-shaped hook to the bottom end of the L-shaped positioning groove to complete the fixation of the cover plate;

[0022] Step 4: When the bottom end of the L-shaped hook contacts the pressing plate and controls the pressing plate to move downward, at this time, the connecting rod drives the piston to move downward, injecting the gas inside the cavity into the inside of the annular air groove through the second air duct and discharging it through the spray holes to blow away the dust on the bottom surfaces of the inner cover plate and the outer cover plate. As the piston continues to move, the gas inside the cavity will be transported to the inside of the first hollow sealing ring and the second hollow sealing ring through the first air duct. The first hollow sealing ring and the second hollow sealing ring expand to complete the sealing of the upper and lower end faces of the outer connecting cylinder and the inner connecting cylinder, and the overall sealing of the dipping tank body is completed;

[0023] Step 5: Connect the top end of the suction pipe to the vacuum pump to evacuate the inside of the dipping tank body and the outer gap. After evacuation, the partition plate blocks the bottom end of the suction pipe to separate the inside of the dipping tank body from the vacuum gap. During use, the dipping tank body can be insulated by vacuum isolation.

[0024] The beneficial effects of the present invention are:

[0025] A dipping tank body with a heat preservation structure and a heat preservation process provided by the present invention. The dipping tank body composed of an inner tank body, an outer tank body, an outer connecting cylinder, an inner connecting cylinder, an inner cover plate, and an outer cover plate can have a double-layer structure after sealing. And through the suction pipe, it is communicated with the inside of the dipping tank body and the internal gap. During the evacuation process, a double-vacuum environment can be formed, effectively avoiding heat loss and having a better heat preservation effect;

[0026] The sealing mechanism composed of a fixed arm, a spline shaft, a shaft hole, a limiting block, a second spring, a bracket, an electric telescopic rod, a sleeve, a vertical guide groove, an arc guide groove, and a guide post between the outer tank body and the outer cover plate is used. During the process of opening the cover plate, through a single electric telescopic rod, not only can the vertical movement of the cover plate be controlled, but also the horizontal rotation of the cover plate can be controlled, so that the tank body can be completely opened for loading and unloading materials, and the control is more convenient and the practicability is higher;

[0027] By evenly arranging L-shaped positioning grooves on the outer side of the outer connecting cylinder, and then cooperating with the L-shaped hooks, positioning support rods, bevel gears, bevel gear rings, transmission gears, and racks on the outer cover to form a rotating assembly, after the cover plate is attached to the top of the connecting cylinder, as the electric telescopic rod continues to move downward, the rotation of the connecting cylinder can be controlled to engage the L-shaped hooks inside the L-shaped positioning grooves, completing the sealing and fixing of the cover plate, which is simple and convenient to use;

[0028] By arranging a cavity, a one-way intake valve, a piston, a connecting rod, a pressing plate, and a first spring inside the L-shaped positioning groove and cooperating with a sealing mechanism composed of a first hollow sealing ring, a second hollow sealing ring, a first air duct, a spray hole, an annular air groove, and a second air duct, not only can the bottom of the cover plate be cleaned during the closing process of the cover plate, but also the gaps between the connecting cylinder and the tank body and the cover plate can be sealed, improving the sealing effect during use.

A cover closing mechanism 9 for controlling the movement of the inner cover plate 5 and the outer cover plate 6 is arranged outside the outer tank body 2.

[0043] Overall working principle: When the outer cover plate 6 is fully opened, it is located on the side of the outer tank body 2. Before dipping in glue, the glue solution and the raw materials for dipping are injected into the interior of the inner tank body 1 together. When performing dipping and sealing, the capping mechanism 9 transfers the inner cover plate 5 and the outer cover plate 6 to the top of the inner connecting cylinder 4 and the outer connecting cylinder 3 and fits them thereto. Using the sealing mechanism 7, the connecting gaps at the upper and lower ends of the inner connecting cylinder 4 and the outer connecting cylinder 3 are sealed, and then the inner cover plate 5 and the outer cover plate 6 are fixed to complete the sealed installation of the dipping tank body. After sealing, the top end of the vacuum pump is connected to the suction pipe 8 to evacuate the interior of the dipping tank body and the outer gap, and then the glue is heated through the heating pipe on the side of the inner tank body 1 to accelerate the dipping process.

[0044] In this embodiment, through holes 801 communicating with the gaps between the inner cover plate 5 and the outer cover plate 6 are provided on the outer side of the suction pipe 8. A limiting ring 802 is fixed at the bottom end of the suction pipe 8, and a partition plate 803 is hingedly installed on the top of the limiting ring 802.

[0045] Local working principle: After evacuating the air, the partition plate 803 blocks the bottom end of the suction pipe 8, separating the interior of the dipping tank body from the vacuum gap.

[0046] In this embodiment, the capping mechanism 9 includes a fixed arm 901, a spline shaft 902, a shaft hole 903, a limiting block 904, a second spring 905, a bracket 906, an electric telescopic rod 907, a rack 918 and a steering assembly. The fixed arm 901 is fixed on the top of the inner cover plate 5. The spline shaft 902 is vertically slidably arranged at the end of the fixed arm 901. A shaft hole 903 matching with the spline shaft 902 is provided on the fixed arm 901. A limiting block 904 is fixed at the top end of the spline shaft 902. A second spring 905 is provided between the bottom of the limiting block 904 and the fixed arm 901. The spline shaft 902 passes through the second spring 905. A bracket 906 is fixedly installed on the side of the inner tank body 1. An electric telescopic rod 907 for controlling the vertical lifting of the spline shaft 902 is provided on the bracket 906.

A steering assembly for controlling the rotation of the inner cover plate 5 around the spline shaft 902 is provided on the bracket 906.

[0047] Local working principle: When capping, the electric telescopic rod 907 is started to control the rotation assembly to move the outer cover plate 6 to directly above the outer connecting cylinder 3, and then the electric telescopic rod 907 is used to control the spline shaft 902 to drive the outer cover plate 6 to move downward until the outer cover plate 6 fits with the top of the outer connecting cylinder 3.

[0048] In this embodiment, the steering assembly includes a sleeve 908, a vertical guide groove 909, an arc-shaped guide groove 910, and a guide post 911. The sleeve 908 is fixed to the top of the bracket 906. The spline shaft 902 passes through the inside of the sleeve 908. A vertical guide groove 909 is vertically formed on the outer side of the sleeve 908. An arc-shaped guide groove 910 is inclined at the top end of the vertical guide groove 909. A guide post 911 is slidably installed inside the vertical guide groove 909 and the arc-shaped guide groove 910. The guide post 911 is fixed to the bottom end on the outer side of the spline shaft 902. The bottom end of the rack 918 is fixedly connected to the output end of the electric telescopic rod 907. The top end of the rack 918 is rotatably connected to the bottom end of the spline shaft 902.

[0049] Local working principle: When the electric telescopic rod 907 controls the spline shaft 902 to drive the outer cover plate 6 to move downward, the guide post 911 slides downward on the inner top of the arc-shaped guide groove 910, and the spline shaft 902 will rotate to control the outer cover plate 6 to move toward the top of the outer connecting cylinder 3. When the guide post 911 enters the inside of the vertical guide groove 909, at this time, the outer cover plate 6 is located directly above the outer connecting cylinder 3.

[0050] In this embodiment, L-shaped hooks 912 are uniformly fixed to the bottom of the outer cover plate 6.

A rotating assembly for controlling the rotation of the outer connecting cylinder 3 is provided on the bracket 906.

[0051] Local working principle: When the outer cover plate 6 moves vertically downward, the L-shaped hooks 912 vertically enter the inside of the L-shaped positioning grooves 913. When the bottom end of the L-shaped hook 912 fits against the top of the pressing plate 705 and presses the pressing plate 705 down by a distance equal to the thickness of the bottom end of the L-shaped hook 912, at this time, the bottoms of the outer cover plate 6 and the inner cover plate 5 are in contact with the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4. The rotation of the outer connecting cylinder 3 is controlled by the rotating assembly to move the end of the L-shaped hook 912 to the inner end of the L-shaped positioning groove 913, completing the fixation of the cover plate.

[0052] In this embodiment, four groups of L-shaped hooks 912 are provided, and the angle between adjacent L-shaped hooks 912 is ninety degrees.

[0054] In this embodiment, the rotating assembly includes a positioning support rod 914, a bevel gear 915, a bevel gear ring 916, and a transmission gear 917. The positioning support rod 914 is fixed to the inner tank body 1. A bevel gear 915 is rotatably installed on the positioning support rod 914. A bevel gear ring 916 is provided at the bottom end of the outer connecting cylinder 3. The bevel gear ring 916 meshes with the bevel gear 915. A transmission gear 917 is installed on the side of the bevel gear 915 through a shaft rod, and the transmission gear 917 meshes with the rack 918.

At the same time, the rack 918 is engaged with the transmission gear 917. When the electric telescopic rod 907 continues to control the spline shaft 902 and the rack 918 to move downward, the limit block 904 will squeeze the fixed arm 901, and the second spring 905 will be compressed, improving the fitting effect between the bottoms of the outer cover 6 and the inner cover 5 and the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4. At the same time, the rack 918 will drive the transmission gear 917 to rotate, and the transmission gear 917 controls the bevel gear 915 to rotate, and the bevel gear 915 controls the outer connecting cylinder 3 to rotate.

A dust removal component is provided at the top of the outer connecting cylinder 3 and the inner connecting cylinder 4.

[0057] Local working principle: When the bottom end of the L-shaped hook 912 contacts the pressing plate 705, first use the dust removal component to remove dust from the bottom surfaces of the inner cover 5 and the outer cover 6, and then the L-shaped hook 912 controls the pressing plate 705 to move downward. At this time, the connecting rod 704 drives the piston 703 to move downward, and the gas inside the cavity 701 is transported to the inside of the first hollow sealing ring 707 and the second hollow sealing ring 708 through the first air duct 709. The first hollow sealing ring 707 and the second hollow sealing ring 708 expand, completing the sealing of the upper and lower end faces of the outer connecting cylinder 3 and the inner connecting cylinder 4, and the overall sealing of the dipping tank body is completed.

[0058] In this embodiment, the dust removal assembly includes a spray hole 710, an annular air groove 711, and a second air duct 712. The annular air groove 711 is opened at the inner top of the outer connecting cylinder 3 and the inner connecting cylinder 4. Spray holes 710 communicating with the inside of the annular air groove 711 are uniformly opened along the circumferences at the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4. A second air duct 712 communicating with the inside of the cavity 701 is provided at the bottom of the annular air groove 711. The opening of the second air duct 712 and the cavity 701 is located above the opening of the first air duct 709 and the cavity 701.

[0059] Local working principle: When the connecting rod 704 drives the piston 703 to move downward, the gas inside the cavity 701 is first injected into the inside of the annular air groove 711 through the second air duct 712 and discharged through the spray holes 710 to blow away the dust on the bottom surfaces of the inner cover plate 5 and the outer cover plate 6.

[0060] As Figures 1 - 8 shown, this embodiment provides a dipping tank body heat preservation process with a heat preservation structure as follows:

[0061] Step 1: When the outer cover plate 6 is fully opened, it is located on the side of the outer tank body 2. At this time, the guide post 911 is located at the top of the arc-shaped guide groove 910. When closing, start the electric telescopic rod 907 to control the spline shaft 902 to drive the outer cover plate 6 to move downward. At the same time, the guide post 911 slides downward inside the arc-shaped guide groove 910, and the spline shaft 902 will rotate to control the outer cover plate 6 to move toward the top of the outer connecting cylinder 3. When the guide post 911 enters the inside of the vertical guide groove 909, at this time, the outer cover plate 6 is located directly above the outer connecting cylinder 3. Continue to control the downward movement of the spline shaft 902 until the bottoms of the outer cover plate 6 and the inner cover plate 5 are in contact with the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4;

[0062] Step 2: When the outer cover plate 6 moves vertically downward, the L-shaped hook 912 vertically enters the inside of the L-shaped positioning groove 913. When the bottom end of the L-shaped hook 912 is in contact with the top of the pressure plate 705 and presses the pressure plate 705 downward by a distance equal to the thickness of the bottom end of the L-shaped hook 912, at this time, the bottoms of the outer cover plate 6 and the inner cover plate 5 are in contact with the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4, but the guide post 911 does not enter the bottom end of the vertical guide groove 909. At the same time, at this time, the rack 918 is engaged with the transmission gear 917;

[0063] Step 3: When the electric telescopic rod 907 continues to control the spline shaft 902 and the rack 918 to move downward, at this time, the limit block 904 will squeeze the fixed arm 901, and the second spring 905 will be compressed, improving the fitting effect between the bottoms of the outer cover plate 6 and the inner cover plate 5 and the tops of the outer connecting cylinder 3 and the inner connecting cylinder 4. At the same time, the rack 918 will drive the transmission gear 917 to rotate, the transmission gear 917 will control the bevel gear 915 to rotate, and the bevel gear 915 will control the outer connecting cylinder 3 to rotate, rotating the bottom end of the L-shaped hook 912 to the bottom end of the L-shaped positioning groove 913 to complete the fixation of the cover plate;

[0064] Step 4: When the bottom end of the L-shaped hook 912 contacts the pressure plate 705 and controls the pressure plate 705 to move downward, at this time, the connecting rod 704 drives the piston 703 to move downward, injecting the gas inside the cavity 701 into the inside of the annular air groove 711 through the second air duct 712 and discharging it through the spray holes 710 to blow away the dust on the bottom surfaces of the inner cover plate 5 and the outer cover plate 6. As the piston 703 continues to move, the gas inside the cavity 701 will be conveyed to the inside of the first hollow sealing ring 707 and the second hollow sealing ring 708 through the first air duct 709. The first hollow sealing ring 707 and the second hollow sealing ring 708 expand to complete the sealing of the upper and lower end faces of the outer connecting cylinder 3 and the inner connecting cylinder 4, and the overall sealing of the dipping tank body is completed;

[0065] Step 5: Connect the top end of the suction pipe 8 to a vacuum pump to evacuate the inside of the dipping tank body and the outer gap. After evacuation, the partition plate 803 blocks the bottom end of the suction pipe 8 to isolate the inside of the dipping tank body from the vacuum gap, and during use, the dipping tank body can be insulated by vacuum isolation.

[0066] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
