Description

Technical Field

[0001] This utility model relates to the technical field of tank lining fixing devices, and more specifically to a device for improving the adhesion of polytetrafluoroethylene (PTFE) tank linings. Background Technology

[0002] A polytetrafluoroethylene (PTFE) storage tank is a storage container with PTFE as the lining or main material. In the conventional manufacturing process, glue is first applied to the inner wall of the tank made of steel or other rigid materials, then PTFE sheets are attached to the inner wall of the tank, and finally the seams of the PTFE sheets are welded to complete the manufacturing of the entire PTFE storage tank.

[0003] The above-mentioned manufacturing method requires high-quality adhesive, as well as a high level of cleanliness in the manufacturing workshop and skilled workers. Otherwise, if the adhesive is contaminated with dust after application or if the adhesive cures too early due to slow worker operation, the adhesion between the PTFE liner and the inner wall of the tank will be insufficient, resulting in the liner detaching during use.

[0004] In order to improve the adhesion between the polytetrafluoroethylene (PTFE) lining and the inner wall of the tank, this utility model proposes a device for improving the adhesion of PTFE storage tank lining. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for improving the adhesion of polytetrafluoroethylene (PTFE) tank linings, so as to solve the problem that the adhesion of existing PTFE tank linings is easily detached due to poor processing.

[0006] This utility model provides the following technical solution: a device for improving the adhesion of polytetrafluoroethylene (PTFE) storage tank linings, comprising: a support cage and an adjustment assembly that can be installed inside a PTFE-lined storage tank, wherein the support cage includes a plurality of clamping rods arranged in a circular pattern, and the plurality of clamping rods simultaneously support the PTFE lining to fit tightly against the inner wall of the storage tank.

[0007] The adjusting component is connected between several clamping rods, and the spacing between adjacent clamping rods can be adjusted evenly through the adjusting component.

[0008] Furthermore, the adjusting assembly includes a lead screw, an adjusting rod, and a threaded sleeve. The lead screw is located among several clamping rods, and the threaded sleeve is threaded onto the surface of the lead screw. One end of the adjusting rod is rotatably connected to the surface of the threaded sleeve, and the other end of the adjusting rod is rotatably connected to the surface of the clamping rod.

[0009] Furthermore, the lead screw has two symmetrically arranged threaded grooves, and there are two sets of threaded sleeves, which are symmetrically arranged on the two sections of the lead screw. The two sets of threaded sleeves are threadedly connected to the two threaded grooves respectively, and each set of threaded sleeves has several adjusting rods.

[0010] Furthermore, the adjustment assembly also includes a foldable protective sleeve, which is fitted onto the threaded groove of the lead screw. A first connecting ring is fixedly installed on the surface of the lead screw, and a second connecting ring is fixedly installed at the end of the threaded sleeve. One end of the protective sleeve is sealed to the first connecting ring, and the other end of the protective sleeve is sealed to the second connecting ring.

[0011] Furthermore, the support cage also includes an auxiliary rod and a drive assembly. The auxiliary rod is rotatably mounted on the side of the clamping rod, and can only rotate in the direction of both ends of the clamping rod. The auxiliary rod can also synchronously tighten the polytetrafluoroethylene lining inside the storage tank along with the clamping rod. The drive assembly is connected between the auxiliary rod and the adjustment assembly, and when the adjustment assembly drives the support cage to open, it can synchronously drive the auxiliary rod to rotate through the drive assembly.

[0012] Furthermore, the drive assembly includes a sliding sleeve, a drive rod, and a push-pull rod. The sliding sleeve is slidably fitted onto the abutment rod. One end of the drive rod is rotatably connected to the surface of the sliding sleeve, and the other end is rotatably connected to the surface of the adjusting rod. One end of the push-pull rod is rotatably connected to the sliding sleeve, and the other end is rotatably connected to the surface of the auxiliary rod.

[0013] Furthermore, the auxiliary rod is arc-shaped, and the curvature is consistent with the curvature of the inner wall of the storage tank.

[0014] Furthermore, the auxiliary rod is a flexible rod and has elasticity.

[0015] Furthermore, the side of the sliding sleeve has a notch facing the inner wall of the storage tank, and the surface of the clamping rod can pass through the notch to contact the polytetrafluoroethylene lining inside the storage tank.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model can adjust the spacing between adjacent clamping rods by adjusting the component to expand it, thereby opening the support cage until the clamping rods are tightened with the polytetrafluoroethylene (PTFE) lining, thus completing the auxiliary fixation of the PTFE lining and improving the adhesion of the PTFE lining.

[0018] 2. In the process of using this utility model, when the adjusting rod rotates, it will synchronously drive the driving rod to move. The driving rod will drive the sliding sleeve to slide on the surface of the pressing rod. The sliding of the sliding sleeve will drive the auxiliary rod to rotate through the push-pull rod, thus forming a cross shape with the pressing rod. At this time, the pressure on the pressing rod will be further dispersed through the auxiliary rod, thereby pressing more parts of the polytetrafluoroethylene lining, and further improving the adhesion of the polytetrafluoroethylene lining.

[0019] 3. In the process of use, the distance between the clamping rods can be freely adjusted by flexibly rotating the screw, thus realizing the adjustment of the size of the entire support cage. This makes the entire device applicable to storage tanks of various sizes, effectively improving its applicability. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The device for improving the adhesion of polytetrafluoroethylene storage tank lining involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figure 1-5 This utility model provides a device for improving the adhesion of polytetrafluoroethylene (PTFE) storage tank linings, comprising: a support cage and an adjustment assembly that can be installed inside a PTFE-lined storage tank 13. The support cage includes a plurality of clamping rods 1 arranged in a circular pattern, which simultaneously support the PTFE lining 13 to fit tightly against the inner wall of the storage tank body 12. The adjustment assembly is connected between the clamping rods 1 and can uniformly adjust the spacing between adjacent clamping rods 1.

[0028] In use, simply place the entire device into the storage tank with the PTFE liner 13 attached, and then adjust the spacing between adjacent clamping rods 1 by adjusting the components to expand it, thereby opening the support cage until the clamping rods 1 are tightly supported by the PTFE liner 13, thus completing the installation of the entire device. At the same time, the entire device will also assist in fixing the PTFE liner 13, thereby improving the adhesion of the PTFE liner 13.

[0029] The adjustment assembly includes a lead screw 2, an adjusting rod 3, and a threaded sleeve 4. The lead screw 2 is located among several clamping rods 1. The threaded sleeve 4 is threadedly installed on the surface of the lead screw 2. One end of the adjusting rod 3 is rotatably connected to the surface of the threaded sleeve 4, and the other end is rotatably connected to the surface of the clamping rod 1.

[0030] Thus, simply rotating the lead screw 2 will drive the threaded sleeve 4 to move. The movement of the threaded sleeve 4 will simultaneously drive the end of the adjusting rod 3 to move. The adjusting rod 3 will then drive the clamping rod 1 away from the lead screw 2, thereby opening the support cage until the clamping rod 1 is pressed against the surface of the polytetrafluoroethylene lining 13 on the inner wall of the storage tank. At this point, the entire support cage will be completely fixed inside the storage tank, thereby achieving auxiliary fixation of the polytetrafluoroethylene lining 13.

[0031] The lead screw 2 has two symmetrically arranged threaded grooves, and there are two sets of threaded sleeves 4, which are symmetrically arranged on the two sections of the lead screw 2. The two sets of threaded sleeves 4 are threadedly connected to the two threaded grooves respectively. At the same time, each set of threaded sleeves 4 has several adjusting rods 3, so that the structure of the whole device can be made more stable.

[0032] The adjustment assembly also includes a foldable protective sleeve 5, which is fitted onto the threaded groove of the lead screw 2. A first connecting ring 6 is fixedly installed on the surface of the lead screw 2, and a second connecting ring 14 is fixedly installed at the end of the threaded sleeve 4. One end of the protective sleeve 5 is sealed to the first connecting ring 6, and the other end of the protective sleeve 5 is sealed to the second connecting ring 14. In this way, contamination of the threaded groove on the lead screw 2 can be prevented, and the threaded sleeve 4 can always move smoothly.

[0033] The support cage also includes an auxiliary rod 7 and a drive assembly. The auxiliary rod 7 is rotatably mounted on the side of the clamping rod 1. The auxiliary rod 7 can only rotate in the direction of both ends of the clamping rod 1. The auxiliary rod 7 can also synchronously tighten the polytetrafluoroethylene lining 13 inside the tank body 12 along with the clamping rod 1. The drive assembly is connected between the auxiliary rod 7 and the adjustment assembly. When the adjustment assembly drives the support cage to open, it can synchronously drive the auxiliary rod 7 to rotate through the drive assembly.

[0034] Thus, during the rotation of the adjusting rod 3, the driving component will be driven to operate synchronously, thereby causing the auxiliary rod 7 to rotate and form a cross with the clamping rod 1. At this time, the pressure on the clamping rod 1 will be further dispersed through the auxiliary rod 7, thereby pressing more parts of the polytetrafluoroethylene lining 13, and further improving the adhesion of the polytetrafluoroethylene lining 13.

[0035] The drive assembly includes a sliding sleeve 8, a drive rod 9, and a push-pull rod 10. The sliding sleeve 8 is slidably sleeved on the abutting rod 1. One end of the drive rod 9 is rotatably connected to the surface of the sliding sleeve 8, and the other end is rotatably connected to the surface of the adjusting rod 3. One end of the push-pull rod 10 is rotatably connected to the sliding sleeve 8, and the other end is rotatably connected to the surface of the auxiliary rod 7.

[0036] Thus, during the rotation of the adjusting rod 3, the driving rod 9 will move synchronously, and the driving rod 9 will cause the sliding sleeve 8 to slide on the surface of the pressing rod 1. The sliding of the sliding sleeve 8 will drive the auxiliary rod 7 to rotate through the push-pull rod 10.

[0037] The auxiliary rod 7 is arc-shaped, and the curvature is consistent with the curvature of the inner wall of the storage tank. This ensures that the auxiliary rod 7 fits more closely to the inner wall of the storage tank.

[0038] The auxiliary rod 7 is a flexible rod with elasticity, so that the auxiliary rod 7 can be elastically deformed to meet the needs of storage tanks of various sizes.

[0039] The side of the sliding sleeve 8 has a notch 11 facing the inner wall of the tank body 12. At the same time, the surface of the clamping rod 1 can pass through the notch 11 and contact the polytetrafluoroethylene lining 13 inside the tank body 12.

[0040] This ensures smooth contact between the clamping rod 1 and the PTFE lining 13, avoids stress concentration caused by poor contact due to the protrusion of the sliding sleeve 8, and further guarantees adhesion.

[0041] It should be noted that all components of this device are made of corrosion-resistant materials or have a corrosion-resistant coating on their surface.

[0042] Therefore, the complete usage process is as follows: First, place the entire device into the storage tank. If the volume is large, it can be hoisted using a crane. Then, limit the adjustment rod 3. The adjustment rod 3 can be tightened using ropes or temporarily limited using other rods. At this time, rotate the lead screw 2, which will drive the threaded sleeve 4 to move. The movement of the threaded sleeve 4 will simultaneously drive the end of the adjustment rod 3 to move. The adjustment rod 3 will then drive the clamping rod 1 away from the lead screw 2, thereby opening the support cage until the clamping rod 1 is pressed against the surface of the polytetrafluoroethylene lining 13 on the inner wall of the storage tank. At this time, the entire support cage will be completely fixed inside the storage tank, thereby achieving auxiliary fixation of the polytetrafluoroethylene lining 13. This will effectively improve the adhesion between the polytetrafluoroethylene lining 13 and the inner wall of the storage tank.

[0043] Meanwhile, during use, as the adjusting rod 3 rotates, it will simultaneously drive the driving rod 9 to move. The driving rod 9 will cause the sliding sleeve 8 to slide on the surface of the pressing rod 1. The sliding of the sliding sleeve 8 will drive the auxiliary rod 7 to rotate through the push-pull rod 10, thus forming a cross shape with the pressing rod 1. At this time, the pressure on the pressing rod 1 will be further dispersed through the auxiliary rod 7, thereby pressing more parts of the polytetrafluoroethylene lining 13, and further improving the adhesion of the polytetrafluoroethylene lining 13.

[0044] In addition, during use, the distance between the clamping rods 1 can be freely adjusted by flexibly rotating the lead screw 2. In this way, the size of the entire support cage can be adjusted, so that the entire device can be used for storage tanks of various sizes, effectively improving its applicability.

[0045] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
