Description

Technical Field

[0001] This utility model relates to the field of furnace body sealing and locking technology, and to an automatic high-pressure resistant toothed locking ring mechanism. Background Technology

[0002] In industrial production, especially in industrial furnace applications involving high pressure and high temperature environments, the sealing and locking mechanisms of the furnace body are crucial. Traditional locking mechanisms typically use mechanical fixing methods such as bolts or clasps. These methods are prone to problems such as poor sealing and component wear under high pressure environments, leading to unstable equipment operation and even safety hazards. In addition, the operation of traditional mechanisms is relatively cumbersome, requiring frequent manual adjustments and maintenance, which increases operating costs and time. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solution: An automatic high-pressure resistant toothed locking ring mechanism, comprising: an upper furnace body and a lower furnace body, a locking ring rotatably disposed between the upper furnace body and the lower furnace body, an upper locking tooth 1 disposed at the opening of the upper furnace body, a lower locking tooth 1 disposed at the opening of the lower furnace body, an upper locking tooth 2 and a lower locking tooth 2 disposed on the inner side of the locking ring, the upper locking tooth 2 disposed above the upper locking tooth 1, the lower locking tooth 2 disposed below the lower locking tooth 1, and both lower tooth surfaces are inclined, a pushing module and a positioning module are disposed on the outer side of the upper furnace body, the working end of the pushing module is disposed on the outer side of the locking ring, and the positioning module includes a guide seat fixedly disposed on the upper furnace body and a centering wheel assembly rotatably disposed on the outer side of the guide seat, the centering wheel assembly abutting against the outer side of the locking ring.

[0005] In a further improvement, the pushing module includes a cylinder mounting base, a cylinder, and a pushing base. The cylinder mounting base is fixedly disposed on the outside of the upper furnace body. The end of the cylinder is rotatably disposed on the cylinder mounting base and a push rod is disposed at the end of its piston rod. The pushing base is disposed on the upper side of the locking ring, and the push rod is rotatably disposed inside the pushing base.

[0006] In a further improvement, the centering wheel assembly includes a locking ring centering wheel shaft, a guide roller, and a pressure cap seat. The locking ring centering wheel shaft is located on the side of the guide seat away from the upper furnace body. The guide roller is rotatably sleeved on the outside of the locking ring centering wheel shaft. The pressure cap seat is located on the lower side of the guide seat.

[0007] In a further improvement, a bearing is provided between the locking ring centering wheel shaft and the guide roller, and two sets of the bearing are provided, with an inner bushing provided between the two sets of the bearing.

[0008] In a further improvement, a limiting module is provided between the upper furnace body and the locking ring. The limiting module includes a limiting plate disposed on the outside of the upper furnace body, a limiting block disposed on the locking ring, and a limiting bolt. The threaded portion of the limiting bolt is threadedly connected to the limiting plate, and its front end abuts against the limiting block.

[0009] In a further improvement, the angle between the lower tooth surface of the second and first lower locking teeth and the horizontal plane is 3°.

[0010] Compared with the prior art, this utility model has the following beneficial effects: This utility model uses a pushing module to drive the locking ring to rotate, thereby realizing the engagement and disengagement of the upper locking tooth 2 with the upper locking tooth 1 and the lower locking tooth 2 with the lower locking tooth 1. When locking is required, the pushing module drives the locking ring to rotate in the forward direction, so that each locking tooth is tightly engaged, thereby firmly connecting the upper furnace body and the lower furnace body together. When unlocking, the pushing module only needs to drive the locking ring to rotate in the reverse direction, so that the locking teeth can quickly disengage from the engagement state, realizing the separation of the upper and lower furnace bodies, significantly reducing the opening and closing time of the equipment and effectively improving production efficiency.

[0019] The following is a description of the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] An automatic high-pressure resistant toothed locking ring mechanism includes: an upper furnace body 1 and a lower furnace body 2. A locking ring 3 is rotatably disposed between the upper furnace body 1 and the lower furnace body 2. An upper locking tooth 11 is disposed at the opening of the upper furnace body 1, and a lower locking tooth 21 is disposed at the opening of the lower furnace body 2. An upper locking tooth 31 and a lower locking tooth 32 are disposed on the inner side of the locking ring 3. The upper locking tooth 31 is disposed on the upper side of the upper locking tooth 11, and the lower locking tooth 32 is disposed on the lower side of the lower locking tooth 21, with both lower tooth surfaces being inclined. A pushing module 4 and a positioning module 5 are disposed on the outer side of the upper furnace body 1. The working end of the pushing module 4 is disposed on the outer side of the locking ring 3 and connected. The positioning module 5 includes a guide seat 51 fixedly disposed on the upper furnace body 1 and a centering wheel assembly 52 rotatably disposed on the outer side of the guide seat 51. The centering wheel assembly 52 abuts against the outer side of the locking ring 3.

[0022] like Figures 1-5As shown, in actual use, the upper locking tooth 11, lower locking tooth 21, upper locking tooth 21, and lower locking tooth 22 are all arranged in a circular array, totaling 18 sets. The width of the upper locking tooth 11 is 15mm smaller than that of the lower locking tooth 21, so that when the locking ring 3 is in the open state, the upper furnace body 1 and the locking ring 3 partially overlap. The upper tooth surface of the upper locking tooth 11 fits against the upper tooth surface of the locking ring 3 during rotation and is coated with grease to reduce friction. In the open state, the lower furnace body 2 can move downward through the gap between the teeth and disengage from the locking ring 3. When closed, the locking ring 3 is rotated so that the lower tooth surface of the lower locking tooth 21 fits against the lower tooth surface of the lower locking tooth 22, and locking is achieved by the inclined tooth surface. During operation, the push module 4 drives the locking ring 3 to rotate, causing the upper locking tooth 31 and the lower locking tooth 32 to engage with the upper locking tooth 11 and the lower locking tooth 21 respectively, achieving a tight connection between the upper furnace body 1 and the lower furnace body 2. At this time, the centering wheel group 52 of the positioning module 5 ensures that the locking ring 3 is precisely aligned and prevents misalignment. During unlocking, the push module 4 drives the locking ring 3 to rotate in the opposite direction, causing the locking teeth to separate. In addition, a sealing ring is provided at the opening of the lower furnace body 2. After the locking ring 3 is locked, a seal is achieved through pre-pressurization of the sealing ring, enhancing the reliability of the equipment.

[0023] As a further preferred embodiment, the pushing module 4 includes a cylinder fixing seat 41, a cylinder 42, and a pushing seat 43. The cylinder fixing seat 41 is fixedly disposed on the outside of the upper furnace body 1. The end of the cylinder 42 is rotatably disposed on the cylinder fixing seat 41, and a push rod 421 is disposed at the end of its piston rod. The pushing seat 43 is disposed on the upper side of the locking ring 3, and the push rod 421 is rotatably disposed inside the pushing seat 43.

[0024] Specifically, when the furnace body needs to be closed, the cylinder 42 of the push module 4 is activated, and its piston rod extends to drive the push rod 421 to push the push seat 43, thereby driving the locking ring 3 to rotate. As the locking ring 3 rotates, the upper locking tooth 31 and the lower locking tooth 32 gradually engage with the upper locking tooth 11 and the lower locking tooth 21, ultimately achieving a tight connection between the upper furnace body 1 and the lower furnace body 2.

[0025] When the furnace body is opened, the piston rod of cylinder 42 extends, driving push rod 421 to push push seat 43. Push seat 43 transmits thrust to locking ring 3, causing it to begin rotating. As locking ring 3 rotates, upper locking tooth 31 gradually separates from upper locking tooth 11, while lower locking tooth 32 gradually separates from lower locking tooth 21. This process gradually weakens the locking force between upper furnace body 1 and lower furnace body 2, ultimately achieving complete opening of the furnace body.

[0026] This invention achieves automatic opening and closing of the furnace body by means of a cylinder, thereby improving efficiency.

[0027] As a further preferred embodiment, the centering wheel assembly 52 includes a locking ring centering wheel shaft 521, a guide roller 522, and a pressure cap seat 523. The locking ring centering wheel shaft 521 is disposed on the side of the guide seat 51 away from the upper furnace body 1. The guide roller 522 is rotatably sleeved on the outside of the locking ring centering wheel shaft 521. The pressure cap seat 523 is disposed on the lower side of the guide seat 51. A bearing 524 is disposed between the locking ring centering wheel shaft 521 and the guide roller 522. Two sets of bearings 524 are provided, and an inner bushing 525 is disposed between the two sets of bearings 524.

[0028] Specifically, during the rotation of the lock ring, it is guided by the guide roller 522 to prevent the lock ring from shifting during rotation and to ensure that the lock ring and the furnace body remain in the center position. Furthermore, the outer layer of the guide roller 411 is coated with an 8mm rigid polyurethane layer to improve wear resistance and extend the service life of the equipment.

[0029] As a further preferred embodiment, a limiting module 6 is provided between the upper furnace body 1 and the locking ring 3. The limiting module 6 includes a limiting plate 61 disposed on the outside of the upper furnace body 1, a limiting block 62 disposed on the locking ring 3, and a limiting bolt 63. The threaded portion of the limiting bolt 63 is threadedly connected to the limiting plate 61, and its front end abuts against the limiting block 62.

[0030] Specifically, by adjusting the screw-in depth of the limit bolt 63, the rotation angle of the locking ring 3 can be precisely controlled, ensuring that the locking ring 3 will not rotate excessively during the closing or opening process, thereby improving the stability and safety of operation.

[0031] As a further preferred embodiment, the angle between the lower tooth surface of the second lower locking tooth 32 and the first lower locking tooth 21 and the horizontal plane is 3°, which improves the locking effect and sealing performance, while facilitating the rotation operation of the locking ring 3 and enhancing the reliability and durability of the equipment.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
