Description

Technical Field

[0001] The utility model belongs to the technical field of crystallization kettles, and particularly relates to a discharging fixing device for an organic acid crystallization kettle. Background Art

[0002] During the crystallization process of succinic acid, the material in the kettle is usually a crystal-containing suspension with certain viscosity and fluidity. During discharging, the material is conveyed from the crystallization kettle to the next process (such as a centrifuge, drying equipment, etc.) through a discharging pipeline (or hose). Since the existing crystallization kettle pipeline lacks fixation, the pipeline will shake during discharging, which causes the connection part to loosen, leading to material leakage, polluting the equipment surface and the ground, and increasing the risk of personnel slipping. For this reason, we propose a discharging fixing device for an organic acid crystallization kettle. Contents of the Utility Model

[0004] As a preference of the above technical solution, the fixing member comprises a threaded rod, the threaded rod is in threaded connection with a fastening nut, the fastening nut abuts against the second fixing plate, the threaded rod is located in the second groove, and one end of the threaded rod is provided with an adapter member, and the adapter member is connected with the first fixing plate.

[0005] As a preference of the above technical solution, the adapter member comprises a rotating shaft rotatably connected with the threaded rod, the first fixing plate is provided with first grooves with the same number as the second grooves, and the rotating shaft is fixed in the first grooves.

[0006] As a preference of the above technical solution, a sealing ring is arranged between the discharging pipe and the adapter.

[0007] The beneficial effects of the utility model are as follows: 1. Through the cooperation of the first fixing plate and the second fixing plate, the utility model forms preliminary limit by the snap connection of the "zhong"-shaped fixing member and the second groove, and then applies axial pressure through the linear adjustment of the threaded rod and the fastening nut, so as to firmly fix the connecting part of the discharging pipe and the material conveying pipe, structurally eliminate the shaking space of the pipeline caused by the impact of material flow, and avoid the loosening of the connecting part caused by long-term shaking; 2. The fixing structure of the utility model ensures the connection stability between the discharge pipe and the adapter, and cooperates with the sealing ring between the two to form a dual guarantee of "mechanical fixing + sealing enhancement". The mechanical fixing prevents the connection part from generating gaps due to shaking, and the sealing ring further fills the possible tiny gaps, fundamentally reducing material leakage, avoiding material contamination of the equipment surface and the ground, lowering the risk of personnel slipping caused by material residue, and improving the safety and neatness of the production environment.

[0010] In order to make the purposes, technical solutions and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below with reference to the embodiments.

[0011] Embodiment As shown in Figure 1 and Figure 2 , the discharging fixing device for the organic acid crystallization kettle comprises a kettle body 10 and a material conveying pipe 20. A discharge pipe 11 is fixedly installed at the bottom of the kettle body 10, one end of the material conveying pipe 20 is fixedly connected with an adapter 21, the adapter 21 is communicated with the discharge pipe 11, the outer rings of the discharge pipe 11 and the adapter 21 are respectively fixedly sleeved with a first fixing plate 12 and a second fixing plate 22, the outer side of the first fixing plate 12 is fixedly connected with a plurality of linearly adjustable fixing members, the fixing members are in a shape of the Chinese character "zhong", the outer side of the second fixing plate 22 is provided with second grooves 23 with the same number as the fixing members, and the second grooves 23 are in snap fit with the fixing members.

[0012] Specifically, by arranging the first fixing plate 12 and the second fixing plate 22 at the adapter 21 on the sides of the discharge pipe 11 and the material conveying pipe 20 respectively, and utilizing the adjustable fixing members on the first fixing plate 12 to snap into the second grooves 23 of the second fixing plate 22, a preliminary fixing relationship is formed, which solves the problem that the existing pipeline lacks fixation. The "zhong" shape design can enhance the snap-fit stability with the second groove 23, and the linear adjustment function provides a basis for subsequent precise fixation.

[0013] As shown in Figure 1 and Figure 2As shown, the fastener includes a threaded rod 30, which is threadedly connected to a fastening nut 32. The fastening nut 32 abuts against the second fixing plate 22. The threaded rod 30 is located in the second groove 23, and an adapter is installed at one end of the threaded rod 30. The adapter is connected to the first fixing plate 12.

[0014] Specifically, the linear adjustment function is achieved through the threaded engagement of the threaded rod 30 and the fastening nut 32. The fastening nut 32 abuts against the second fixing plate 22. By tightening the fastening nut 32, axial pressure can be applied to tightly fix the first fixing plate 12 and the second fixing plate 22, further eliminating the gap of pipe shaking. The threaded rod 30 is located in the second groove 23, which not only ensures the accuracy of the installation position of the fastener, but also connects to the first fixing plate 12 through the adapter to form a complete force transmission path.

[0015] like Figure 2 As shown, the adapter includes a rotating shaft 31 that is rotatably connected to the threaded rod 30. The fixing plate 12 has the same number of grooves 13 as the grooves 23, and the rotating shaft 31 is fixed in the groove 13.

[0016] Specifically, the threaded rod 30 is connected to the fixing plate 12 via the rotating shaft 31, and the rotating shaft 31 can rotate relative to the threaded rod 30, so that the angle of the threaded rod 30 can be flexibly adjusted during the adjustment process, which is convenient for precise alignment and engagement with the groove 23. The same number of grooves 13 as groove 23 are provided to provide installation space for the rotating shaft 31, while enhancing the structural stability of the fixing plate 12 and preventing deformation of the fixing plate due to the force of the fixing parts.

[0017] like Figure 2 As shown, a sealing ring is provided between the discharge pipe 11 and the adapter 21.

[0018] It should be noted that a sealing ring is installed between the discharge pipe 11 and the adapter 21 to fill any gaps and prevent material leakage due to loose connections or poor sealing.

[0019] Working in conjunction with the aforementioned fixing structure, the fixing structure prevents the connection from loosening due to pipe vibration, while the sealing ring further blocks the leakage path at the physical contact level, providing double protection to reduce pollution and safety risks. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
