Description

Technical Field

[0001] This utility model relates to the technical field of polymer material processing equipment, and more specifically, to a sealing structure for a polymer material mixing tank. Background Technology

[0002] In coal mining, rock mass reinforcement is a crucial step in ensuring mining safety. Polymer materials for rock mass reinforcement in coal mines have been widely used in this field due to their excellent adhesion, rapid curing speed, and good mechanical properties. These polymer materials are typically composed of multiple components and require thorough mixing in a mixing tank before use to ensure their performance meets requirements. The mixing tank generally consists of a tank body and a stirring shaft. The stirring shaft rotates at high speed driven by a motor, thereby agitating the materials inside the tank. However, due to the unique properties of polymer materials for rock mass reinforcement in coal mines, such as their high viscosity which makes them prone to adhering to the stirring shaft during mixing and migrating towards sealing areas as the shaft rotates; and the fact that some materials also possess certain chemical corrosiveness, long-term contact can cause erosion of sealing components.

[0003] In the prior art, during the stirring of polymer materials using stirring equipment, the friction between the materials and the friction between the stirring shaft and the materials generates a lot of heat, which raises the internal temperature of the stirring tank. Under high temperature conditions, the seals between the stirring shaft and the stirring tank are prone to aging and failure, resulting in material leakage. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a sealing structure for a polymer material mixing tank, which solves the technical problem that in the prior art, friction between materials and friction between the stirring shaft and the material generates a lot of heat, causing the internal temperature of the mixing tank to rise. Under high temperature conditions, the seal between the stirring shaft and the mixing tank is prone to aging and failure, resulting in material leakage.

[0005] According to one aspect, at least one embodiment of the present invention provides a sealing structure for a polymer material mixing tank, comprising: The mixing tank body has a sealing component at its top and a cooling component at one of its upper ends. The sealing assembly includes a sealing flange, which is two sets of symmetrically separated semi-cylindrical structures. The surface of the sealing flange is provided with a bolt mounting groove. The two sets of sealing flanges are fixedly connected by bolts. The bottom end of the sealing flange is fixedly connected to the top end of the mixing tank body by bolts. The cooling assembly includes a cooling water tank and cooling pipes. The cooling water tank is fixedly installed at the upper end of the mixing tank body, and the cooling pipes are sleeved on the outside of the sealing flange.

[0006] For example, in a sealing structure for a polymer material mixing tank provided in at least one embodiment of the present invention, the following are further included: a water inlet is fixedly connected to the upper end of the cooling water tank, a second sealing cap is threadedly connected to the upper end of the water inlet, a water pump is fixedly connected to the top of the cooling water tank, a water pump is fixedly connected to the input end of the water pump, a water pump pipe is fixedly connected to the end of the water pump away from the water pump and extends to the bottom of the cooling water tank, a water inlet pipe is fixedly connected to the input end of the cooling pipe, and a return pipe is fixedly connected to the output end of the cooling pipe.

[0007] For example, in a sealing structure for a polymer material mixing tank provided in at least one embodiment of the present invention, the water inlet pipe is fixedly connected at one end away from the cooling pipe to the output end of the water pump, and the return pipe is fixedly installed at one end away from the cooling pipe at the top of the cooling water tank.

[0008] For example, in a sealing structure for a polymer material mixing tank provided in at least one embodiment of the present invention, the sealing assembly further includes a small fan and a mechanical seal shaft, wherein the small fan is disposed inside the sealing flange and its bottom end is fixedly connected to the mixing tank body.

[0009] For example, in a sealing structure for a polymer material mixing tank provided in at least one embodiment of the present invention, the sealing flange is further provided with a spiral groove on its inner wall, heat exchange fins are fixedly connected to the inner wall of the sealing flange, and a sealing gasket is fixedly connected to the connection surface of the sealing flange.

[0010] For example, in at least one embodiment of the present invention, a sealing structure for a polymer material mixing tank is provided, which further includes: the mixing tank body includes a stirring motor, the stirring motor is fixedly installed on the top of the sealing flange, the output shaft of the stirring motor is fixedly connected to a stirring shaft, and the stirring shaft passes through the top of the mixing tank body and is rotatably connected to the mixing tank body.

[0011] For example, in a sealing structure for a polymer material mixing tank provided in at least one embodiment of the present invention, the mechanical seal shaft is fixedly sleeved on the outside of the mixing shaft, and the bottom end of the mechanical seal shaft is fixedly connected to the top end of the mixing tank body.

[0013] The beneficial effects of the embodiments of this utility model are as follows: In this invention, a cooling assembly is installed, with cooling pipes fitted onto the surface of the sealing flange. A water pump injects cooling water into the cooling pipes to cool the surface of the sealing flange, thereby reducing the internal temperature of the sealing flange and preventing the mechanical seal shaft from being constantly at a high temperature, thus extending its service life. The addition of heat exchange fins further enhances the cooling effect of the cooling pipes by transferring heat from the air inside the sealing flange to the flange itself. A small fan circulates the air inside the sealing flange, enhancing the heat exchange effect and increasing the heat absorption capacity of the heat exchange fins. The spiral grooves allow air to flow directionally along the spiral channel, forming an orderly spiral airflow and preventing air stagnation in localized areas. This further enhances the transfer of heat from the air to the heat exchange fins, thereby further improving the cooling effect of the cooling pipes on the sealing flange, preventing the mechanical seal shaft from aging due to high temperatures, extending its service life, and reducing equipment maintenance costs.

[0023] like Figures 1-3 As shown, it illustrates a sealing structure for a polymer material mixing tank according to one embodiment of the present invention, comprising: The mixing tank body 1 has a sealing component 2 at its top and a cooling component 3 at one of its upper ends. The sealing assembly 2 includes a sealing flange 21, which is a set of two symmetrically separated semi-cylindrical structures. The surface of the sealing flange 21 is provided with a bolt mounting groove 22. The two sets of sealing flanges 21 are fixedly connected by bolts. The bottom end of the sealing flange 21 is fixedly connected to the top end of the mixing tank body 1 by bolts. The cooling assembly 3 includes a cooling water tank 31 and a cooling pipe 36. The cooling water tank 31 is fixedly installed at the upper end of the mixing tank body 1, and the cooling pipe 36 is sleeved on the outside of the sealing flange 21.

[0024] A water inlet 32 ​​is fixedly connected to the upper end of the cooling water tank 31. A second sealing cap 33 is threadedly connected to the upper end of the water inlet 32. A water pump 34 is fixedly connected to the top of the cooling water tank 31. A water pump pipe 35 is fixedly connected to the input end of the water pump 34. The end of the water pump pipe 35 away from the water pump 34 is fixedly connected to the cooling water tank 31 and extends to the bottom of the interior of the cooling water tank 31. A water inlet pipe 37 is fixedly connected to the input end of the cooling pipe 36. A return pipe 38 is fixedly connected to the output end of the cooling pipe 36.

[0025] The end of the water inlet pipe 37 away from the cooling pipe 36 is fixedly connected to the output end of the water pump 34, and the end of the return pipe 38 away from the cooling pipe 36 is fixedly installed at the top of the cooling water tank 31.

[0026] In some examples, the surface of the sealing flange 21 is cooled by the cooling assembly 3 to prevent the mechanical seal shaft 26 from being in a high-temperature state and thus prolonging its service life. Cooling water is stored in the cooling water tank 31, and cooling water can be added to the interior of the cooling water tank 31 through the water inlet 32. The cooling water is drawn from the interior of the cooling water tank 31 by the water pump 34 and injected into the water inlet pipe 37. After entering the interior of the cooling pipe 36 through the water inlet pipe 37, the cooling water absorbs the heat from the surface of the sealing flange 21 to reduce its internal temperature. The cooling water that has absorbed the heat flows back to the interior of the cooling water tank 31 through the return pipe 38 for recycling.

[0027] For example, such as Figures 3-4 As shown, the sealing assembly 2 also includes a small fan 25 and a mechanical seal shaft 26. The small fan 25 is located inside the sealing flange 21 and its bottom end is fixedly connected to the mixing tank body 1.

[0028] The inner wall of the sealing flange 21 is provided with a spiral groove 23, and heat exchange fins 24 are fixedly connected to the inner wall of the sealing flange 21. A sealing gasket 27 is fixedly connected to the surface of the connection of the sealing flange 21.

[0029] The mixing tank body 1 includes a stirring motor 12, which is fixedly installed on the top of the sealing flange 21. The output shaft of the stirring motor 12 is fixedly connected to a stirring shaft 13, which passes through the top of the mixing tank body 1 and is rotatably connected to the mixing tank body 1.

[0030] The mechanical seal shaft 26 is fixedly sleeved on the outside of the stirring shaft 13, and the bottom end of the mechanical seal shaft 26 is fixedly connected to the top end of the mixing tank body 1.

[0031] An observation glass 11 is fixedly connected to one side of the surface of the mixing tank body 1. An inlet 14 is fixedly connected to one side of the upper end of the mixing tank body 1. A sealing ring 15 is fixedly connected to the top of the inlet 14. A first sealing cap 16 is threadedly connected to the top of the inlet 14.

[0032] In some examples, by setting a sealing component 2, the connection between the stirring shaft 13 and the top of the mixing tank body 1 is sealed to prevent leakage of polymer materials, reduce waste and pollution, and ensure the safety of coal mining. The sealing flange 21 consists of two sets of semi-cylindrical structures, which are connected by bolts and fixed to the mixing tank body 1 at the bottom by bolts. The bolt fixing method not only facilitates the installation and disassembly of the sealing flange 21, but also facilitates the maintenance and replacement of its internal mechanical seal shaft 26. In addition, a sealing gasket 27 is set at the connection of the sealing flange 21, which increases the sealing performance of the sealing flange 21 during use and further increases the sealing performance of the device. By creating spiral grooves 23 on the inner wall of the sealing flange 21 and installing heat exchange fins 24, and using a small fan 25 to circulate the air inside the sealing flange 21, the air inside the flange can fully contact the heat exchange fins 24, allowing the air to fully absorb the heat emitted by the stirring shaft 13 and the mechanical seal shaft 26. This facilitates the transfer of heat from the sealing flange 21 to the cooling pipe 36, thereby enhancing the cooling effect of the cooling pipe 36. The spiral grooves 23 also allow the air to flow directionally along the spiral channel, forming an orderly spiral airflow and preventing air from stagnating in local areas, further enhancing the effect of the air transferring heat to the heat exchange fins 24. The observation glass 11 allows staff to easily observe the internal condition of the mixing tank body 1, and the sealing ring 15 and the first sealing cover 16 can seal the feed inlet 14.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
