Description

Technical Field

[0001] This utility model relates to the field of laser cladding sealing technology, specifically a laser cladding sealing device for the PTFE lining joint of a chemical storage tank. Background Technology

[0002] Chemical storage tanks are a type of storage tank, categorized into metal tanks, non-metal tanks, and metal-non-metal composite tanks. The seams of the PTFE lining in chemical storage tanks require sealing. Laser cladding, also known as laser bonding or laser coating, is a novel surface modification technology. It involves adding cladding material to the surface of a substrate and using a high-energy-density laser beam to fuse it together with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer on the base layer. Laser cladding refers to a process where external materials are added to the molten pool formed after laser irradiation of the substrate, either synchronously or pre-placed, and both materials are rapidly solidified to form a coating layer.

[0003] In response, Chinese patent application number CN215668210U discloses a laser cladding nozzle and laser cladding equipment, relating to the field of laser cladding technology, aimed at saving the operating temperature of the laser cladding nozzle while reducing the operating cost of the nozzle and laser cladding process. The laser cladding nozzle includes an outer cylinder, an end cap, and an inner cylinder. The outer cylinder has a through-hole first cavity, and at least two powder feeding holes and at least two water passage holes are provided on the outer cylinder. The end cap is sealed and fitted onto the end of the outer cylinder near the outlet of the laser cladding nozzle, and a receiving cavity is formed between the end cap and the outer cylinder, with the water passage holes communicating with the receiving cavity. The inner cylinder has a first end and a second end, extending from the first end to the second end, with the first end housed within the first cavity. A powder passage cavity is formed between the first end and the outer cylinder, communicating with the powder feeding holes. This utility model also provides a laser cladding equipment including a powder feeder, a laser cladding nozzle, and the laser cladding nozzle described in the above technical solution.

[0004] However, in actual use, the nozzles do not have a guiding mechanism when conveying materials. If too much material is conveyed or there is a large accumulation in one place, it is easy to flow down, resulting in poor overall collection and guiding effect. At the same time, when performing laser cladding sealing operations on chemical storage tanks, it is necessary to move around the chemical storage tank, which makes the overall operation quite cumbersome. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a laser cladding sealing device for the PTFE lining seam of a chemical storage tank, in order to solve the problems mentioned in the background art, where the nozzle does not have a guiding mechanism when conveying materials, and the material is prone to flow down when too much is conveyed or a large amount is accumulated in one place, resulting in poor overall collection and guiding effect. At the same time, the laser cladding sealing operation of the chemical storage tank requires moving around the chemical storage tank, which makes the overall operation cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cladding sealing device for the PTFE lining joint of a chemical storage tank, comprising a base plate, a control panel fixedly connected to the right side of the base plate, a cladding box installed on the top surface of the base plate, a conveying box provided on the upper surface of the cladding box, a connecting pipe installed at the front end of the conveying box, and a conveying nozzle body provided at the front end of the connecting pipe.

[0007] A stabilizing ring is installed on the outer surface of the conveying nozzle body. A connecting frame is fixedly connected to the lower end of the stabilizing ring. A heat-resistant electric telescopic rod is installed on the top surface of the connecting frame. A top frame is installed on the top surface of the heat-resistant electric telescopic rod. A guide ring is provided at the front end of the top frame. A limit half ring is installed on the top surface of the guide ring.

[0008] Preferably, a groove is provided inside the right side of the cladding box, and a heating box is arranged inside the groove.

[0009] Preferably, a placement tray is mounted on the surface of the base plate, and a drive motor is provided at the lower end of the placement tray.

[0010] Preferably, the drive motor is installed inside the base plate, and the output end of the drive motor is fixedly connected to the lower surface of the placement tray.

[0011] Preferably, a limiting ring is installed on the top surface of the placement tray, and a pushing column is inserted inside the limiting ring.

[0012] Preferably, a fastening ring is installed on the outer surface of the push column, and four sets of both the push column and the fastening ring are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The laser cladding sealing device for the PTFE lining seam of this chemical storage tank, consisting of a connecting pipe, a conveying nozzle body, a stabilizing ring, a connecting frame, a heat-resistant electric telescopic rod, a top frame, a guide ring, and a limiting half-ring, works as follows: During operation, material is drawn from the cladding box via a conveying box and sprayed onto the outer surface of the PTFE lining seam through the connecting pipe and the conveying nozzle body. This forms a metallurgically bonded cladding layer on the outer surface of the PTFE lining seam. Simultaneously, before spraying, the heat-resistant electric telescopic rod moves the top frame to a suitable height until the guide ring adheres to the outer side of the PTFE lining seam. The design of the guide ring and limiting half-ring effectively guides excess material, preventing it from flowing down the outer surface of the chemical storage tank. The overall performance is good, effectively guiding and limiting the material, demonstrating the practicality of the design.

[0015] 2. The laser cladding sealing device at the PTFE lining joint of the chemical storage tank, through the setting of a heating box, placement plate, limiting ring, drive motor, push column, and fastening ring, allows for the heating of the material inside the cladding box during use. During the sealing operation, the chemical storage tank is first placed on the top surface of the placement plate, and the limiting ring limits its position. Then, by pushing the push column on the outer surface of the limiting ring, the fastening ring is made to fit against the outer surface of the chemical storage tank, thus sealing the tank. The drive motor rotates the placement plate, allowing it to rotate during subsequent laser cladding sealing. Therefore, the entire connecting pipe and conveying nozzle body do not need to be moved. The overall operation offers good sealing performance and is convenient, demonstrating the functionality of the design. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A laser cladding sealing device for the PTFE lining joint of a chemical storage tank. The control panel 2, cladding box 3, conveying nozzle body 6, heat-resistant electric telescopic rod 9, heating box 14, and drive motor 17 used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be elaborated further here. The device includes a base plate 1, with the control panel 2 fixedly connected to the right side of the base plate 1. The cladding box 3 is installed on the top surface of the base plate 1. A conveying box 4 is provided on the upper surface of the cladding box 3. A connecting pipe 5 is installed at the front end of the conveying box 4, and a conveying nozzle body 6 is installed at the front end of the connecting pipe 5. A groove is formed inside the right side of the cladding box 3, and the heating box 14 is installed inside the groove. A placement plate 15 is installed on the surface of the base plate 1, and a drive motor 17 is installed at the lower end of the placement plate 15. The drive motor 17 is installed inside the base plate 1, and its output end is fixedly connected to the lower surface of the placement plate 15. The top surface of the placement plate 15 is... A limiting ring 16 is installed, and a push column 18 is inserted inside the limiting ring 16. A fastening ring 19 is installed on the outer surface of the push column 18. There are four sets of push columns 18 and fastening rings 19. The heating box 14 is equipped with multiple sets of electric heating rods to assist in heating the water inside the heating box 14. The design of the heating box 14 can heat up the material inside the cladding box 3. During the sealing operation, the chemical storage tank is first placed on the top surface of the placement plate 15 and limited by the design of the limiting ring 16. Then, the push column 18 is pushed by the outer surface of the limiting ring 16, so that the fastening ring 19 can fit against the outer surface of the chemical storage tank, thereby sealing the position of the chemical storage tank. Then, the placement plate 15 can be rotated by the design of the drive motor 17, so that it can be rotated during the subsequent laser cladding sealing. Thus, the entire connecting pipe 5 and the conveying nozzle body 6 do not need to be moved. The overall operation has good sealing performance and is relatively convenient.

[0024] A stabilizing ring 7 is installed on the outer surface of the conveying nozzle body 6. A connecting frame 8 is fixedly connected to the lower end of the stabilizing ring 7. A heat-resistant electric telescopic rod 9 is installed on the top surface of the connecting frame 8. A top frame 10 is installed on the top surface of the heat-resistant electric telescopic rod 9. A guide ring 11 is set at the front end of the top frame 10. A limiting half-ring 12 is installed on the top surface of the guide ring 11. The material inside the cladding box 3 is extracted through the conveying box 4 and sprayed onto the outer surface of the PTFE lining joint of the chemical storage tank through the connecting pipe 5 and the conveying nozzle body 6. This forms a metallurgically bonded cladding layer on the outer surface of the PTFE lining joint of the chemical storage tank. At the same time, before spraying, the top frame 10 is moved to a suitable height by the heat-resistant electric telescopic rod 9 until the guide ring 11 is attached to the outside of the PTFE lining joint of the chemical storage tank. The design of the guide ring 11 and the limiting half-ring 12 can guide excess material and prevent it from flowing down the outer surface of the chemical storage tank. The overall effect is good and the material can be guided and limited.

[0025] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical support. Material is then extracted from the cladding box 3 via the conveyor box 4 and sprayed onto the outer surface of the PTFE lining seam of the chemical storage tank via the connecting pipe 5 and the conveying nozzle body 6. This forms a metallurgically bonded cladding layer on the outer surface of the PTFE lining seam. Simultaneously, before spraying, the top frame 10 is moved to a suitable height using the heat-resistant electric telescopic rod 9 until the guide ring 11 is fitted against the outer side of the PTFE lining seam of the chemical storage tank. The design of the guide ring 11 and the limiting semi-ring 12 guides excess material, preventing it from being carried away by the outer surface of the chemical storage tank. The material flows down the surface. The heating box 14 is designed to heat the material inside the cladding box 3. During the sealing operation, the chemical storage tank is first placed on the top surface of the placement plate 15 and limited by the design of the limiting ring 16. Then, by pushing the pushing column 18 on the outer surface of the limiting ring 16, the fastening ring 19 can fit against the outer surface of the chemical storage tank, thereby sealing the position of the chemical storage tank. Then, the placement plate 15 can be rotated by the design of the drive motor 17, so that it can be rotated during the subsequent laser cladding sealing. Thus, the entire connecting pipe 5 and the conveying nozzle body 6 do not need to be moved. The above is the working principle of this utility model.
