Description

Technical Field

[0001] This utility model relates to the technical field of m-diethylbenzene production, and more specifically, to a m-diethylbenzene refining apparatus. Background Technology

[0002] In many fields, such as chemical production, m-diethylbenzene is an important material that often needs to be transferred between different devices, such as between main equipment and storage tanks. The sealing of the connections between these devices is crucial to the entire material transfer process.

[0003] In existing diethylbenzene (DEP) transfer devices, the connection between the main body and the storage tank often suffers from poor sealing. Traditional sealing methods may simply use conventional gaskets or basic sealing structures. However, with prolonged use, due to material erosion, equipment vibration, and environmental factors, gaps can easily appear at these seals, leading to leakage of DEP during transfer. This not only wastes materials and increases production costs but may also pollute the surrounding environment. Furthermore, due to the chemical properties of DEP, leakage poses certain safety hazards, such as the potential for fire or explosion, affecting the safety of the entire device's operation and the stability of material transfer. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a diethylbenzene refining apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diethylbenzene refining apparatus, comprising a main body, wherein a storage tank is connected to the outside of the main body via a conduit; further comprising a movable component for sealing the connection between the main body and the storage tank; and a positioning component for restricting the movable component during use; the movable component comprises: a fixing ring, the fixing ring being fixedly installed on the surface of the conduit, a turntable being rotatably connected inside the fixing ring, a sliding rod being slidably connected to the surface of the turntable, a moving rod being hinged to the outside of the sliding rod, a moving plate being mounted on the surface of the moving rod, a sealing block being fixedly installed at the bottom of the moving plate, and a sealing strip being slidably connected to the inner side of the sealing block.

[0006] Preferably, a movable spring is fixedly installed on the inner side of the sealing strip, the movable spring is fixedly installed inside the sealing block, and a control rod is fixedly installed on the outer side of the turntable, the control rod passing through the fixing ring.

[0007] Preferably, the positioning component includes: a connecting ring, which is fixedly installed on the top of the fixed ring, and a positioning block is fixedly installed inside the connecting ring.

[0008] Preferably, a sliding rod is slidably connected to the surface of the control rod, a fixing plate is fixedly installed on the top of the sliding rod, and an insert rod is fixedly installed on the bottom of the fixing plate, the insert rod being inserted into the inner side of the positioning block.

[0009] Preferably, a return spring is fixedly installed on the surface of the sliding rod, and the return spring is fixedly installed on the top of the control rod.

[0010] Preferably, the turntable surface has an arc-shaped groove, the outer side of the fixing ring has a groove, and the top of the connecting ring has an annular groove.

[0011] Preferably, there are three sealing blocks, and the three sealing blocks are arranged in a circular array with the center point of the turntable as the center.

[0012] The technical effects and advantages of this utility model are as follows: 1. Compared with existing technologies, this diethylbenzene refining unit, through the arrangement of movable components, allows the operator to rotate a control lever to drive the turntable to rotate within a fixed ring when sealing the connection between the main body and the storage tank. The sliding rod rotates with the turntable and, due to its hinged connection with the moving rod, drives the moving rod to move, causing the moving plate to move closer to the center point of the turntable. The sealing blocks, driven by the moving plate, move closer to the connection point, and the sealing strip, relying on the elasticity of the movable spring, tightly adheres to the surface of the connection point. Multiple sealing blocks and the sealing strip work together to fill the gaps and achieve a seal, preventing diethylbenzene leakage and ensuring safe operation of the unit and stable material transfer.

[0013] 2. Compared with the existing technology, this diethylbenzene refining device, through the setting of the fixing components, has a connecting ring at the top of the fixing ring, including a positioning block. Before rotating the control rod, the fixing plate is pulled up to move the insertion rod upward, thereby releasing the restriction of the insertion rod by the positioning block, and then the turntable can be rotated. After the turntable has rotated, the fixing plate is released, and the sliding rod is reset under the action of the reset spring. After the insertion rod is reset, it is inserted back into the inner side of the connecting ring. The positioning block restricts the insertion rod, preventing the turntable from rotating accidentally, thus improving the stability and fixing effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1 As attached Figures 1 to 4 The apparatus shown includes a main body 1, and a storage tank 3 is connected to the outside of the main body 1 via a conduit 2. It also includes a movable component 4 for sealing the connection between the main body 1 and the storage tank 3; Positioning component 5 is used to restrict the use of active component 4; The active component 4 includes: a fixing ring 41, which is fixedly installed on the surface of the conduit 2. A turntable 42 is rotatably connected inside the fixing ring 41. A slide rod 43 is slidably connected to the surface of the turntable 42. A moving rod 44 is hinged to the outside of the slide rod 43. A moving plate 45 is installed on the surface of the moving rod 44. A sealing block 46 is fixedly installed at the bottom of the moving plate 45. A sealing strip 47 is slidably connected to the inside of the sealing block 46.

[0022] A movable spring 48 is fixedly installed inside the sealing strip 47. The movable spring 48 is fixedly installed inside the sealing block 46. A control rod 49 is fixedly installed on the outside of the turntable 42. The control rod 49 passes through the fixing ring 41. When the sealing strip 47 is used for a long time and its surface is worn, the contact distance between the sealing strip 47 and the connection can be adjusted by rotating the turntable 42.

[0023] Specifically: With the movable component 4 in place, when sealing the connection between the main body 1 and the storage tank 3, the operator rotates the control lever 49 to drive the turntable 42 to rotate within the fixed ring 41. The slide rod 43 rotates with the turntable 42, and is hinged to the moving rod 44, causing the moving rod 44 to move, thus moving the moving plate 45 closer to the center point of the turntable 42. The sealing block 46, driven by the moving plate 45, approaches the connection point, and the sealing strip 47, relying on the elasticity of the movable spring 48, tightly adheres to the surface of the connection point. Multiple sealing blocks 46 and sealing strip 47 work together to fill the gaps and achieve a seal.

[0024] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figure 5 As shown below, see details: In a preferred embodiment, the positioning component 5 includes: a connecting ring 51, which is fixedly installed on the top of the fixed ring 41; a positioning block 52 is fixedly installed inside the connecting ring 51; a sliding rod 53 is slidably connected to the surface of the control rod 49; a fixing plate 54 is fixedly installed on the top of the sliding rod 53; an insert rod 55 is fixedly installed on the bottom of the fixing plate 54; the insert rod 55 is inserted into the inner side of the positioning block 52; and a return spring 56 is fixedly installed on the surface of the sliding rod 53, which is fixedly installed on the top of the control rod 49. The return spring 56 can help the sliding rod 53 quickly return to its initial position, making it convenient to adjust the sealing state again by rotating the turntable 42 through the control rod 49.

[0025] In a preferred embodiment, the surface of the turntable 42 is provided with an arc-shaped groove 420, which allows the turntable 42 to slide against the slide rod 43 when it rotates. The outer side of the fixing ring 41 is provided with a groove 410, which facilitates the connection between the turntable 42 and the control rod 49. The top of the connecting ring 51 is provided with an annular groove 510, which facilitates the placement of the positioning block 52.

[0026] In a preferred embodiment, three sealing blocks 46 are provided, and the three sealing blocks 46 are arranged in a circular array with the center point of the turntable 42 as the center. The circular array distribution of the three sealing blocks 46 can achieve relatively comprehensive and uniform coverage of the connection between the main body 1 and the storage tank 3. When the sealing blocks 46 are moved towards the connection and perform the sealing operation by the moving plate 45, they can seal the gaps at the connection from different angles and directions, leaving no dead corners in the seal.

[0027] The working process of this utility model is as follows: First, when it is necessary to seal the connection between the main body 1 and the storage tank 3, the operator can drive the turntable 42 to rotate inside the fixed ring 41 by rotating the control rod 49 that passes through the fixed ring 41 on the outside of the turntable 42. The fixed ring 41 plays the role of supporting and positioning the turntable 42, ensuring that it can rotate stably around the center. When the turntable 42 rotates, the sliding rod 43 that is slidably connected to its surface will move with the rotation of the turntable 42. Since the outer side of the sliding rod 43 is hinged to the moving rod 44, the movement of the sliding rod 43 will drive the moving rod 44 to perform corresponding movements. The moving rod 44 changes angle with the hinge point between itself and the sliding rod 43 as the axis, thereby driving the moving plate 45 mounted on the surface to move closer to the turntable. The center point of the disc 42 moves. When the moving plate 45 moves, the sealing block 46 fixed at the bottom of the moving plate 45 will change position under the action of the moving rod 44. The three sealing blocks 46 arranged in a circular array move synchronously and gradually move closer to the connection between the main body 1 and the storage tank 3. The sealing strip 47 slidably connected to the inner side of the sealing block 46 maintains an outward elastic force under the action of the moving spring 48, so that the sealing strip 47 can fit tightly against the surface of the connection. Through the coordinated cooperation of multiple sealing blocks 46 and sealing strip 47, the gap at the connection is filled, thereby achieving a good sealing effect, preventing diethylbenzene from leaking from the connection during the transmission process, and improving the safety of the device operation and the stability of material transmission.

[0028] The connecting ring 51 is fixedly installed on the top of the fixed ring 41, and a positioning block 52 is fixedly installed inside it. When the control lever 49 needs to rotate to drive the turntable 42 to rotate, the fixed plate 54 needs to be pulled upward first, so that the fixed plate 54 drives the insertion rod 55 to move upward. When the insertion rod 55 moves upward, the positioning block 52 will release the restriction on the insertion rod 55, so that the turntable 42 can be driven to rotate by operating the control lever 49. After the turntable 42 has finished rotating, the pull on the fixed plate 54 can be manually released, so that the sliding rod 53 at the bottom of the fixed plate 54 is reset under the action of the return spring 56, and drives the insertion rod 55 to reset. After the insertion rod 55 is reset, it will be re-inserted into the inner side of the connecting ring 51. The positioning block 52 restricts the insertion rod 55 to prevent the turntable 42 from rotating and deviating due to accidental force, thereby improving the stability and fixing effect of the movable component 4.

[0029] The above describes the working principle of the diethylbenzene refining unit.
