Description

Technical Field

[0001] This utility model relates to a disassembly tool, specifically a device for separating the lining and steel sleeve of a hydrothermal reactor. Background Technology

[0002] In the fields of materials science and chemical engineering, hydrothermal reactors are the core equipment for realizing hydrothermal reactions. They are mainly composed of a steel sleeve and an inner liner. After being sealed, chemical reactions are carried out in a high-temperature and high-pressure environment. However, with the increase of the number of times the hydrothermal reactor is used, the inner wall of the steel sleeve will gradually rust under the corrosive effect of the chemical substances inside the reactor. Moreover, under long-term high temperature and high pressure, the inner liner will deform over time. Both the rusting of the inner wall of the steel sleeve and the deformation of the inner liner will change the fit between the inner liner and the steel sleeve, making it difficult to separate.

[0003] Currently, in practical operation, when the steel sleeve and inner lining of a hydrothermal reactor are difficult to separate, manual labor is usually relied upon to forcibly separate them using simple tools. This has several drawbacks: 1) The lack of a precise pressure and angle control structure means that the force applied during separation cannot be precisely applied to the adhered parts. In other words, the magnitude and direction of the applied force are difficult to stabilize, and each separation operation requires a lot of time and manpower, resulting in low efficiency; 2) Hydrothermal reactors of different sizes have different structures, and commonly used tools lack height and position adjustment and adaptive components. It is difficult to adjust the separation operation according to the characteristics of hydrothermal reactors of different sizes, resulting in the inability to achieve universal adaptation for hydrothermal reactors of various sizes and limiting the flexibility of experimental operations; 3) The lack of a buffer device means that during the forced separation process, the instantaneous impact force directly acts on the inner lining and steel sleeve of the hydrothermal reactor, which can easily cause damage to the inner lining and steel sleeve of the hydrothermal reactor, shorten their service life, and increase the cost of use. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for separating the inner lining and steel sleeve of a hydrothermal reactor, which improves the efficiency of separating the inner lining and steel sleeve of the hydrothermal reactor and has strong applicability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for separating the lining and steel sleeve of a hydrothermal reactor includes a base and a pressing rod. A vertical fixing rod is fixedly installed on the base, and the surface of the fixing rod is uniformly provided with slots.

[0007] One end of the pressure sleeve rod is fixedly connected to a retaining ring, and the opposite side of the retaining ring is slidably connected to a pressure rod. The end of the pressure rod is fixedly installed with a pressure plate for clamping the steel shell of the hydrothermal reactor, and the pressure rod is sleeved with a first spring. The two ends of the first spring are fixedly connected to the retaining ring and the pressure plate, respectively.

[0008] The retaining ring is fixedly connected to a connecting rod, and the connecting rod is connected to a connecting ring via a ball bearing. The inner surface of the connecting ring is fixed with a buckle that matches the retaining groove.

[0009] The base is provided with a lifting block for supporting the inner lining of the hydrothermal reactor. The lifting block is located directly below the retaining ring.

[0010] Furthermore, a handle is fixedly installed at one end of the pressure rod, and the surface of the handle has a texture.

[0011] Furthermore, the base surface has a groove for placing the hydrothermal reactor, and a slide rail is provided on one side of the groove. The slide rail is slidably connected to a slider for abutting the bottom of the hydrothermal reactor.

[0012] Furthermore, the tablet is arc-shaped.

[0013] Furthermore, the ball bearing has a hole at its tail end, and a pusher is slidably connected inside the hole. A second spring is fixedly connected to one end of the pusher. The second spring is located inside the hole, and one end of the second spring is fixedly connected to the inner wall of the hole.

[0014] The connecting ring has a through hole on one side that corresponds to the position of the hole, and the other end of the pusher head is slidably connected to the inside of the through hole.

[0015] Furthermore, the base is provided with a rubber seat, and the lifting block is placed on the rubber seat.

[0016] Furthermore, the surface of the rubber seat has a regular texture.

[0017] Furthermore, the rubber seat is a block structure made of elastic rubber.

[0018] Compared with the prior art, this utility model has the following technical effects:

[0019] This invention utilizes a combination of slots and buckles to adjust the height of the pressure sleeve rod and retaining ring, facilitating precise vertical positioning of hydrothermal reactors of different sizes. By pressing the pressure sleeve rod, the angle of the retaining ring is adjusted under the action of the ball bearing. The retaining ring applies a downward force to the steel shell, coordinating the lifting force exerted by the lifting block on the inner lining. This gradually overcomes the adhesion between the inner lining and the steel sleeve caused by rust and deformation, gradually separating the inner lining from the steel shell. Simultaneously, the elastic restoring force of the first spring causes the pressure plate to grip the steel shell, evenly distributing the clamping force and reducing pressure damage to the steel shell surface. In short, this invention improves the accuracy and flexibility of force transmission, solving the problem of unstable force magnitude and direction in existing technologies. It not only shortens the time of a single separation operation by 60%–80%, significantly improving separation efficiency and saving manpower, but also reduces damage to the reactor and has good applicability.

[0020] The use of slide rails and sliders allows for flexible horizontal positioning of the hydrothermal reactor, facilitating the opening of the reactor's steel cover with a pry bar, thus improving the device's versatility.

[0021] By setting a second spring and a pusher, the elastic restoring force of the second spring presses the pusher against the surface of the fixed rod, which makes it easy to securely fasten the buckle inside the slot, facilitates the application of a downward force to the steel shell, and makes it easier to further control the magnitude and direction of the pressure and transmit the pressure evenly.

[0022] By setting up a rubber seat, the lifting block can provide lifting force for separation, and it can also buffer external force, reducing the force applied to the lining of the hydrothermal reactor at the moment of application, and effectively preventing damage to the lining.

[0027] The specific content of this utility model will be further explained in detail below with reference to the embodiments.

[0028] like Figures 1-3 As shown, a device for separating the lining and steel sleeve of a hydrothermal reactor includes a basic support assembly, a pressure regulation assembly, an auxiliary separation assembly, and a transmission and positioning assembly.

[0029] The basic support assembly includes a base 5, with a vertical fixing rod 1 fixedly installed at one end of the base 5. The base 5 is flat and provides a stable support platform for the entire device. The surface of the base 5 has a groove for placing the hydrothermal reactor. A slide rail 6 is provided on one side of the groove. A slider 7 is slidably connected to the slide rail 6. When the bottom of the hydrothermal reactor is placed inside the groove, the slider 7 is pushed in from one side of the groove. The slider 7 is inserted into the slide rail 6 and abuts against the bottom of the hydrothermal reactor. Since the side of the hydrothermal reactor is a flat surface, the slider 7 is pressed against the flat surface, making it easy to open the steel cover of the hydrothermal reactor with a pry bar.

[0030] The pressure regulating component includes a long rod-shaped pressure sleeve rod 2. A handle is fixedly installed at one end of the pressure sleeve rod 2. The handle has a textured surface for easy manual gripping. A retaining ring 12 is fixedly installed at the other end of the pressure sleeve rod 2. A pressure rod 16 is slidably connected to the opposite surface of the retaining ring 12. An arc-shaped pressure plate 14 is fixedly installed at the end of the pressure rod 16. A first spring 17 is sleeved at one end of the pressure rod 16. The first spring 17 is located between the pressure plate 14 and the retaining ring 12. Both ends of the first spring 17 are fixedly connected to the retaining ring 12 and the pressure plate 14, respectively. When the upper end of the steel shell extends into the retaining ring 12 and is located between the two pressure plates 14, the first spring 17 is squeezed and compressed. Under the action of the elastic restoring force of the first spring 17, the two pressure plates 14 are pressed tightly against the surface of the steel shell, thereby holding the steel shell tightly.

[0031] The retaining ring 12 is fixedly connected to a connecting rod, the axis of which is on the same straight line as the axis of the pressure sleeve rod 2. One end of the connecting rod is connected to a connecting ring 15 through a ball bearing 10. A buckle 8 is fixedly provided on the inner surface of the connecting ring 15. The surface of the fixing rod 1 is evenly provided with slots 13 that match the buckles 8. The fixing rod 1 passes through the connecting ring 15. By cooperating with the buckles 8 and the slots 13, the vertical position of the pressure sleeve rod 2 relative to the base 5 can be adjusted. At the same time, by holding the handle and rotating it, the angle of the retaining ring 12 can be adjusted, thereby accurately adjusting the pressure direction and the point of application.

[0032] The ball bearing 10 has an opening at its tail end and a pusher 9 is slidably connected thereto. A second spring 11 is fixedly installed at one end of the pusher 9. The second spring 11 is located inside the opening at the tail end of the ball bearing 10, and both ends of the second spring 11 are fixedly connected to the pusher 9 and the ball bearing 10, respectively. A through hole is opened on one side of the connecting ring. One end of the pusher 9 is slidably inserted into the through hole, pushing the pressure sleeve rod 2. The fixing rod 1 squeezes the pusher 9, so that the second spring 11 is in a compressed state. The buckle 8 is disengaged from the slot 13, thereby adjusting the up and down position of the buckle 8 and inserting it into the slot 13 at the required height. When the buckle 8 is inserted into the slot 13, the elastic restoring force of the second spring 11 pushes the pusher 9 toward the fixing rod 1 until it abuts against the surface of the fixing rod 1, so that the buckle 8 is firmly inserted into the slot 13, making the pressure sleeve rod 2 more stable during the application of force.

[0033] The auxiliary separation component includes a rubber seat 4 set on the base 5, a lifting block 3 placed at the center of the rubber seat 4, the lifting block 3 being located directly below the retaining ring 12, the shape of the lifting block 3 being designed according to the bottom shape of the hydrothermal reactor, its upper surface being flat, and placed on the rubber seat 4, the rubber seat 4 being a block made of elastic rubber with irregular texture on the surface, the rubber seat 4 being used to buffer external force and uniformly transmit force.

[0034] The transmission positioning assembly includes a slider 7, a pusher 9, a ball bearing 10, and a second spring 11. The slider 7 and the slide rail 6 are used to fix the hydrothermal reactor and facilitate the removal of the steel cover. The pusher 9 and the second spring 11 are used to securely lock the buckle 8 into the slot 13. The ball bearing 10 is used to apply a downward force to the steel shell.

[0035] The working principle of this utility model is as follows:

[0036] 1) Preliminary preparation: According to the size of the hydrothermal reactor, use the slide rail 6 and slider 7 on the base 5 to fix the hydrothermal reactor in the groove opened on the base 5. Then use a pry bar to unscrew the steel cover of the hydrothermal reactor. According to the height of the steel shell, select a suitable height of the slot 13 and put the buckle 8 into the slot 13. Under the elastic restoring force of the second spring 11, push the push head 9 to press against the surface of the fixing rod 1, so that the buckle 8 is locked in the slot 13, thereby adjusting the retaining ring 12 of the pressure sleeve rod 2 to a suitable height.

[0037] 2) Pressure application: Place the reactor on the lifting block 4, and fit the upper end of the reactor into the retaining ring 12. Under the elastic restoring force of the first spring, a set of pressure plates 14 clamp the steel shell surface of the reactor. The operator holds the handle, presses the pressure sleeve rod 2, and adjusts the angle of the retaining ring 12 through the ball bearing 10 to apply a downward force to the steel sleeve.

[0038] 3) Synergistic separation: The lifting block 4 applies an upward lifting force to the inner lining, which works synergistically with the force applied to the steel shell surface by the pressure rod 2. This gradually overcomes the adhesion between the inner lining and the steel shell caused by rust and deformation, allowing the inner lining to gradually separate from the steel shell. During this process, the elasticity of the rubber seat 4 buffers the instantaneous impact force, preventing damage to the hydrothermal reactor lining caused by rigid contact. At the same time, the surface texture of the rubber seat 4 increases the friction, making the force transmission more stable.
