Description

Technical Field

[0001] This utility model relates to the storage field, specifically to a stirring device for a silicone sealant storage tank with anti-filler sedimentation function. Background Technology

[0002] In the production process of silicone sealant, fillers such as calcium carbonate and fumed silica are added to enhance the sealant's strength or reduce costs. During the storage of silicone sealant, these fillers may settle due to factors such as gravity, causing the fillers and other additives in the silicone sealant to form layers. This leads to a decrease in the sealing effect of the silicone sealant, failing to achieve the expected sealing effect. The stirring devices installed in existing silicone sealant storage tanks mostly use a single propeller or stirring rod for stirring, which is difficult to stir the silicone sealant adhering to the inner wall of the storage tank and cannot effectively deal with the local settlement of fillers and other additives on the inner wall of the storage tank. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a stirring device for silicone sealant storage tank with anti-filler sedimentation function, so as to solve the technical problem of filler sedimentation during silicone sealant storage.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stirring device for a silicone sealant storage tank with anti-filler sedimentation function, comprising a tank body and a support column. The tank body is composed of a conical structure at the lower end and a cylindrical structure at the upper end. An stirring component for preventing filler sedimentation is provided inside the tank body. A power component for providing power to the stirring device is fixedly connected to the top of the tank body.

[0005] The power assembly includes a first motor and a drive shaft, which is rotatably connected to the central axis of the tank.

[0006] The stirring assembly includes a first spiral ribbon, a second spiral ribbon, multiple first support plates, multiple second support plates, and multiple scrapers. The first spiral ribbon is fixedly connected to the side wall of the drive shaft by multiple first support plates. The central axis of the first spiral ribbon is on the same straight line as the central axis of the drive shaft. The side of the first spiral ribbon away from the drive shaft is in contact with the inner wall of the tank. The second spiral ribbon is fixedly connected to the drive shaft by multiple second supports. The maximum diameter of the second spiral ribbon is smaller than the maximum diameter of the first spiral ribbon. The second spiral ribbon and the first spiral ribbon have the same length. The central axis of the second spiral ribbon is on the same straight line as the central axis of the drive shaft. The scrapers are uniformly fixedly connected to the bottom end of the drive shaft, and the scrapers are in contact with the inner wall of the bottom end of the tank.

[0007] By adopting the above technical solution, the cylindrical space provides ample mixing space for the mixing component, ensuring that the material can be uniformly stirred within a larger space, and providing a larger storage space. The conical structure allows the material to naturally gather to the bottom under the action of gravity, facilitating discharge. The first spiral band in the mixing component adheres to the inner wall of the tank, effectively scraping off the material attached to the tank wall and preventing the filler from adhering to the tank wall and causing sedimentation. The second spiral band stirs the material in the middle of the tank, forming an internal and external cooperation with the first spiral band, improving the overall uniformity of mixing. The scraper at the bottom adheres to the inner wall of the tank bottom, which can scrape the material at the bottom of the tank in a timely manner, preventing the filler from settling at the bottom and ensuring the uniformity of the silicone sealant. The power component provides stable power for mixing, ensuring that the mixing component works continuously and efficiently, further enhancing the anti-settling effect.

[0008] Furthermore, the tank body has a discharge port at the bottom, and a discharge pipe is fixedly connected to the discharge port. A screw rod for discharging is rotatably connected inside the discharge pipe, and a second motor for controlling the rotation of the screw rod is provided at the discharge pipe.

[0009] By adopting the above technical solution, a discharge port is set at the bottom of the tank and connected to a discharge pipe with a screw rod. The material is conveyed by the rotation of the screw rod. Compared with the traditional direct discharge method, it can effectively avoid material blockage at the discharge port. Especially for silicone sealant with high viscosity, this structure can make the discharge process smoother. The second motor controls the rotation of the screw rod, which can flexibly adjust the discharge speed and discharge volume to meet the discharge needs in different scenarios.

[0010] Furthermore, a liquid level window for observing the liquid level is provided on the side wall of the tank, and a thermometer is fixedly connected to the outer wall of the tank.

[0011] By adopting the above technical solution, the liquid level window on the side wall of the tank allows the operator to intuitively observe the liquid level of the material in the tank, making it easy to keep track of the remaining material and prevent the agitator from running dry. The thermometer can monitor the temperature of the material in the tank in real time. Since the performance of silicone sealant is greatly affected by temperature, the ambient temperature or agitation speed can be adjusted to ensure that the material remains stable at a suitable temperature.

[0012] Furthermore, a sealing gasket is provided at the tank connection to prevent moisture from entering the tank.

[0013] By adopting the above technical solution, the sealing gasket set at the tank connection can effectively prevent external moisture from entering the tank. Silicone sealant is relatively sensitive to moisture, and moisture may cause the sealant to undergo a chemical reaction, affecting its performance and quality. Good sealing performance can also prevent the materials in the tank from deteriorating due to excessive contact with the outside air, thus extending the storage time of the materials.

[0014] Furthermore, the drive shaft is connected to the first motor via a speed reducer.

[0015] By adopting the above technical solution, the drive shaft and the first motor are connected by a reducer. The reducer can convert the high-speed rotation output by the motor into the appropriate speed required by the drive shaft, so as to avoid excessive shearing of the material by the stirring component due to excessive speed, which would affect the performance of the silicone sealant.

[0016] Furthermore, the drive shaft, the first spiral belt, the second spiral belt, the first support plate, the scraper, and the second support plate are all made of 316 stainless steel.

[0017] By adopting the above technical solutions, 316 stainless steel has excellent corrosion resistance, which can resist the corrosion of components by chemicals that may be contained in silicone sealant, extend the service life of these key components, reduce downtime and maintenance caused by component corrosion damage, and lower maintenance costs.

[0018] Furthermore, the tank body connection is rigidly connected by bolts.

[0019] By adopting the above technical solution, the tank body is rigidly connected by bolts. This connection method can ensure that the connection between the various parts of the tank is firm. When the stirring component vibrates at high speed, the tank body will not loosen or shift, thus ensuring the stability of the overall structure of the device.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention utilizes a first spiral belt to scrape off adhering materials from the tank wall and push the materials upwards, thus agitating materials prone to localized settling and preventing such settling. A second spiral belt, working in conjunction with the first spiral belt in the middle of the tank, allows for the exchange and agitation of materials adhering to the tank wall with those in the middle, resulting in better mixing. A bottom scraper further agitates the materials at the bottom of the tank, preventing localized settling. The combined effect of these three components comprehensively prevents localized settling of the packing material on the tank wall and bottom. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In this example:

[0028] A stirring device for a silicone sealant storage tank with anti-filler sedimentation function, such as Figure 1-3 As shown, the device includes a tank body 1 and support columns 2. The support columns 2 are symmetrically distributed around the bottom of the tank body 1, providing stable support for the entire device and ensuring that the tank body 1 will not shake or tip over during the stirring process. The tank body 1 consists of a conical structure at the lower end and a cylindrical structure at the upper end. The cylindrical part occupies most of the height of the tank body 1, and the internal space is spacious, which facilitates the stirring components to carry out large-scale stirring. The conical part smoothly transitions from the bottom of the cylindrical part, and the tapered design is reasonable, which can guide the material to gather at the bottom. The tank body 1 is equipped with a stirring component to prevent the filler from settling. The top of the tank body 1 is fixedly connected to a power component to provide power to the stirring device.

[0029] The power assembly includes a first motor 3 and a drive shaft 4. The first motor 3 is selected with an appropriate power. One end of the drive shaft 4 is connected to the first motor 3, and the other end extends into the tank body 1. The drive shaft 4 is rotatably connected to the central axis of the tank body 1. The drive shaft 4 is rotatably connected to the tank body 1 through bearings and other connecting parts. During rotation, the friction is small and the stability is high. The central axis coincides with the central axis of the tank body 1, so that the stirring assembly can evenly stir the material around the center of the tank body 1, avoid the stirring from being biased, and ensure the uniformity of the stirring of materials in each area of ​​the tank.

[0030] The stirring assembly includes a first spiral belt 5, a second spiral belt 6, multiple first support plates 7, multiple second support plates 8, and multiple scrapers 9. The first spiral belt 5 is fixedly connected to the side wall of the drive shaft 4 via multiple first support plates 7. One end of each first support plate 7 is firmly welded or bolted to the drive shaft 4, and the other end is tightly fixed to the inner side of the first spiral belt 5. The support plates are evenly spaced, and the central axis of the first spiral belt 5 is on the same straight line as the central axis of the drive shaft 4, with their central axes completely overlapping. This ensures that the first spiral belt 5 is subjected to uniform force and the stirring action is stable when rotating. The side of the first spiral belt 5 away from the drive shaft 4 is in close contact with the inner wall of the tank 1. The degree of contact is moderate, neither too tight, which would cause excessive friction and affect rotation, nor too loose, which would leave a stirring dead corner. This allows the material adhering to the tank wall to be scraped off and stirred, preventing the material from settling and accumulating on the tank wall, and ensuring the uniformity of the filling in the tank wall area. The second spiral belt 6 is fixedly connected to the drive shaft 4 by multiple second supports 8, so that the second spiral belt 6 is stably installed on the drive shaft 4, ensuring that it can continuously and effectively stir the material in the middle of the tank 1. The maximum diameter of the second spiral belt 6 is smaller than the maximum diameter of the first spiral belt 5. The second spiral 6 and the first spiral belt 5 have the same length, forming an inner and outer layer of stirring range, which complements the first spiral belt 5 and acts on the middle and edge areas of the tank 1 respectively, improving the overall stirring comprehensiveness. The central axis of the second spiral belt 6 is on the same straight line as the central axis of the drive shaft 4, ensuring that the material in the middle of the tank 1 is stirred evenly. The scraper 9 is evenly fixedly connected to the bottom end of the drive shaft 4. The scraper 9 is in contact with the inner wall of the bottom end of the tank 1 and is firmly connected to the drive shaft 4. It can rotate synchronously with the drive shaft 4, and can thoroughly scrape up the filler remaining at the bottom of the tank and mix it into the overall material, ensuring that the filler will not settle in the bottom area of ​​the tank.

[0031] See Figure 1 , Figure 2 The tank body 1 has a discharge port 10 at the bottom, which is located at the lowest point of the conical tank body 1 to facilitate the concentrated flow of materials. The discharge port 10 is fixedly connected to a discharge pipe, and a screw rod 12 for discharging is rotatably connected inside the discharge pipe. The screw rod 12 has a small gap with the inner wall of the discharge pipe, and can push the material along the pipe when it rotates. A second motor 11 is provided at the discharge pipe to control the rotation of the screw rod 12. The discharge state can be adjusted by controlling the start and stop of the motor and the speed.

[0032] See Figure 1 The tank body 1 has a liquid level window 14 on its side wall for observing the liquid level. The liquid level window 14 is made of transparent and corrosion-resistant material. The installation position is convenient for operators to observe, and the scale is clear. A thermometer 13 is fixedly connected to the outer wall of the tank body 1 to monitor the material temperature in real time. If the temperature is too high, the packing will easily settle. The thermometer 13 can make it easy to observe the temperature inside the tank and make it convenient for staff to adjust it in time.

[0033] See Figure 3 The tank body 1 is provided with a sealing gasket 15 at the connection to prevent moisture from entering the tank body 1, to prevent material leakage inside the storage tank, and to prevent outside air and moisture from entering, and to prevent the silicone sealant from curing prematurely when it comes into contact with water.

[0034] See Figure 1 The drive shaft 4 is connected to the first motor 3 through a reducer, which can adjust the speed and torque as needed to adapt to the stirring work requirements.

[0035] See Figure 2 The drive shaft 4, the first spiral belt 5, the second spiral belt 6, the first support plate 7, the scraper 9, and the second support plate 8 are all made of 316 stainless steel. 316 stainless steel has excellent corrosion resistance and strength, and can adapt to the material environment inside the tank and the intensity of stirring work.

[0036] See Figure 1 , Figure 3 The tank body 1 is rigidly connected by bolts at the connection points. After tightening, the various parts of the tank body 1 are tightly connected, with high connection strength, ensuring that the structure of the tank body 1 is stable and will not loosen during the stirring process.

[0037] The implementation principle of this embodiment is as follows: After the silicone sealant material is injected into the tank 1, the support column 2 stably supports the entire device. In the power assembly at the top, the first motor 3 drives the transmission shaft 4 to rotate stably on the central axis of the tank 1 through the reducer. The transmission shaft 4 drives the stirring assembly to operate fully. The first spiral belt 5 is fixed by the first support plate 7 and begins to rotate around the transmission axis. Because it is in contact with the inner wall of the tank 1 and its central axis is consistent with the transmission shaft 4, it scrapes the material near the tank wall and pushes it upward when rotating. The second spiral belt 6 is fixed to the transmission shaft 4 through the second support plate 8. The second spiral belt 6 rotates around the axis of the transmission shaft 4. Its diameter is smaller than that of the first spiral belt 5 and its central axis coincides with the axis of the transmission shaft 4. It pushes the material in the middle of the tank 1. During stirring, the first spiral belt 5 and the second spiral belt 6 are of the same length and form a stirring zone with internal and external cooperation within the same height range. The scraper 9 at the bottom of the drive shaft 4 is in contact with the inner wall of the tank bottom and scrapes the material at the bottom of the tank as the drive shaft 4 rotates. The three work together to prevent the packing from settling on the tank wall, middle and bottom, and to ensure that the material is uniform. During the stirring process, the operator observes the liquid level through the liquid level window 14 and monitors the temperature through the thermometer 13 to keep track of the material status in a timely manner. The sealing gasket 15 at the connection of the tank body 1 prevents water vapor from entering, and the bolt rigid connection ensures the stability of the tank body 1. When discharging, the second motor 11 drives the spiral rod 12 in the discharge pipe to rotate, so that the material gathered at the discharge port 10 at the bottom of the tank can be smoothly discharged.
