Description

Technical Field

[0001] This utility model relates to the field of sealant installation technology for bolted storage tanks, and more specifically to an adaptive application device for sealant in bolted storage tanks. Background Technology

[0002] In landfill leachate treatment systems, cylindrical anaerobic digesters are key pieces of equipment, and their installation quality and sealing performance directly affect the stability and efficiency of the entire treatment system. During the installation of the anaerobic digester, the fastening bolts, as crucial components connecting various parts of the digester, are particularly important for their sealing. However, in practice, due to the large size of the anaerobic digester and the numerous, widely distributed fastening bolts, the application of sealant becomes extremely tedious and complex.

[0003] Traditional sealant application methods often involve manual application using a hand-held brush or spray gun. This approach is not only inefficient but also struggles to guarantee even application and a proper seal. The large application area and high requirement for uniformity present numerous challenges to traditional methods in practical applications. Firstly, manual application makes it difficult to ensure that every bolt is adequately covered with sealant, leading to missed areas or uneven application, thus affecting the sealing effect. Secondly, temperature control during the application process is also a significant challenge, as the viscosity and flowability of the sealant are greatly affected by temperature; excessively high or low temperatures will negatively impact the application results. Utility Model Content

[0004] The present invention aims to provide an adaptive application device for sealant in bolted storage tanks to solve the problem of uneven application of sealant in existing bolted storage tanks.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adaptive application device for sealant in a storage tank, comprising a shell, a sealant storage tank, a nozzle, and a drive assembly. The nozzle is connected to one end of the shell, the drive assembly is connected to the other end of the shell, and the bottom end of the shell is connected to the sealant storage tank. The drive assembly is used to extract and heat the sealant in the sealant storage tank and then spray it through the nozzle.

[0006] The working principle of this utility model is as follows: The sealant is stored in a sealant tank. The lifting device is controlled by a switch to push the partition and press the sealant into the outer shell. After the sealant enters the outer shell, the drive component heats the sealant according to the ambient temperature and the sealant enters the nozzle. The drive component drives the nozzle to apply the sealant to the fastening bolts under pressure.

[0007] The beneficial effects of this utility model are as follows: The adaptive application device for sealant in bolted storage tanks proposed in this utility model can adjust the sealant outlet temperature by using an adaptive heating device and can freely adjust the sealant outlet pressure by using a pressure balancing system, so that the sealant can be applied evenly.

[0008] Furthermore, the drive assembly includes a handle, a lifting device switch, a lifting device, a heating wire, and a pressure balancer. The lifting device is connected to the inner bottom of the sealant tank, and a baffle plate is connected to the top of the lifting device, with sealant attached to the baffle plate. The handle is connected to the bottom of the outer casing, located on the side away from the nozzle. The lifting device switch is connected to the middle of the handle and is electrically connected to the lifting device. The heating wire is connected to the inner wall of the middle section of the outer casing and is electrically connected to a power source. The pressure balancer is connected to the end of the outer casing away from the nozzle and is used to control the pressure of the sealant at the nozzle outlet. During operation, pressing the lifting device switch on the handle activates the lifting device, delivering the sealant from the sealant tank into the outer casing. The heating wire then heats the sealant, melting it. The pressure balancer is activated, causing the melted sealant inside the outer casing to be extruded from the nozzle under pressure and applied to the surface of the fastening bolts.

[0009] Furthermore, the lifting device is a hydraulic cylinder, which is connected to the inner bottom of the sealant storage tank. The output end of the hydraulic cylinder is connected to the partition plate, and the hydraulic cylinder is electrically connected to the lifting device switch. During operation, pressing the lifting device switch on the handle activates the hydraulic cylinder. The output shaft of the hydraulic cylinder drives the partition plate upward, simultaneously squeezing the sealant in the sealant storage tank upward into the outer shell.

[0010] Furthermore, the nozzle is fan-shaped, with baffles connected to the upper and lower ends of its outer side, and a brush connected to the outer wall of the nozzle, positioned between the baffles. The nozzle shape and the brush arrangement ensure that the sealant is evenly applied to the bolts during spraying, and the brush cleans the surface of the bolts before application.

[0011] Furthermore, the width of one end of the nozzle connected to the housing is greater than the width of the nozzle's outlet end. This inconsistent width at both ends of the nozzle allows the sealant to be extruded quickly from the nozzle.

[0012] Furthermore, the pressure balancer includes an adjusting bolt and a spring. The spring is connected inside the housing, and one end of the spring is connected to a pressure balancing block located on the other side of the connection between the sealant reservoir and the housing and nozzle. The adjusting bolt is threaded onto the end of the housing away from the nozzle, and passes through the housing to connect to the other end of the spring. During operation, after the sealant melts due to heating by the heating wire, rotating the adjusting bolt adjusts the pressure inside the housing, causing the spring to tighten. After the sealant melts, under the elastic force of the spring, the pressure balancing block squeezes the sealant into the nozzle. Attached Figure Description

The sealing adhesive storage tank 6 is threadedly connected to the bottom end of the housing 5 through an internal threaded interface 64. The housing 5 is threadedly connected to the right end of the nozzle 4 through an external threaded interface 52. The nozzle 4 is a vertical fan shape, and the width of the right end of the nozzle 4 is greater than the width of the left end of the nozzle 4. Horizontal baffles 42 are fixedly connected to the upper and lower ends of the left side of the nozzle 4. A brush 41 is fixedly connected to one side of the outer wall of the nozzle 4. The brush 41 is located between the baffles 42. The brush 41 is slidably connected to the surface of the fastening bolt 3. The fastening bolt 3 connects the lower layer 1 of the anaerobic tank body and the upper layer 2 of the anaerobic tank body.

[0020] The drive assembly includes a handle 7, a lifting device switch 8, a hydraulic cylinder 61, a heating wire 51, and a pressure balancer 9. The hydraulic cylinder 61 is fixedly connected to the inner bottom of the sealant storage tank 6. A partition 62 is fixedly connected to the output axis of the hydraulic cylinder 61, and sealant 63 is slidably connected to the partition 62. The handle 7 is fixedly connected to the bottom of the outer casing 5, and the handle 7 is located on the side away from the nozzle 4. The lifting device switch 8 is fixedly connected to the middle of the handle 7 and is electrically connected to the hydraulic cylinder 61. The heating wire 51 is fixedly connected to the inner wall of the middle part of the outer casing 5 and is electrically connected to a power source.

[0021] The specific implementation process is as follows: The sealant 63 is stored in the sealant storage tank 6. Press the lifting device switch 8 on the handle 7. At this time, the hydraulic cylinder 61 operates. The output shaft of the hydraulic cylinder 61 drives the partition 62 to move upward. At the same time, it squeezes the sealant 63 in the sealant storage tank 6 upward to the outer shell 5. At this time, the heating wire starts to heat up, so that the sealant 63 melts. Rotate the adjusting bolt 91 to adjust the pressure inside the outer shell 5, so that the melted sealant 63 inside the outer shell 5 is squeezed out from the nozzle 4 under the pressure of the spring 92. At this time, it drives the entire device to move horizontally. The brush 41 first cleans the surface of the fastening bolt 3. After cleaning, the sealant 63 sprayed from the nozzle 4 acts on the surface of the fastening bolt 3. The baffles 42 above and below the nozzle 4 prevent the sealant 63 from overflowing to the upper and lower ends.
