[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] As Figs. 1-5 The utility model discloses a vertical high temperature sulfuric acid pump's mounting structure, including sulfuric acid pump base 1 and bolt 2, sulfuric acid pump base 1 is rectangle, four corners of sulfuric acid pump base 1 are equipped with a bolt hole 11, and the bolt body of bolt 2 can pass through bolt hole 11, still including mounting component 12 and mounting seat 5, mounting component 12 sets up under sulfuric acid pump base 1, the position of mounting component 12 is matched with the position of bolt hole 11, and is fixedly connected with sulfuric acid pump base 1, and the recess 51 that is matched with mounting component 12 in quantity and size is equipped on mounting seat 5, the outer wall of mounting component 12 is equipped with buckle assembly groove 121, the inner wall of recess 51 is equipped with buckle base body piece 53 that is matched with buckle assembly groove 121, and mounting component 12 and mounting seat 5 are connected through buckle. The bottom of recess 51 is equipped with spring 52, the lower end of spring 52 is fixedly connected with recess 51, and the upper end of spring 52 is contacted with the lower surface of buckle base body piece 53 under the action of elastic force. Spring 52 can effectively slow down the vibration of vertical high temperature sulfuric acid pump when working, avoid the influence of vibration on fastening bolt, make the phenomenon that bolt loosens and falls off. The vertical movable slot 122 of mounting component 12 is set up in the vertical direction middle position, ensures that the two side walls of mounting component 12 are stressed when installing, and is contracted to vertical movable slot 122. When using, the mounting component 12 of sulfuric acid pump base 1 is aligned with the recess 51 on mounting seat 5, then is inserted into recess 51, until buckle assembly groove 121 and buckle base body piece 53 are connected together, and are preliminarily fixed, wherein the vertical movable slot 122 on mounting component 12 can make mounting component 12 have the space that can be deformed, is helpful to buckle assembly groove 121 and buckle base body piece 53 successful buckle connection.

[0022] As Figs. 3-5As shown, in this embodiment, after the mounting component 12 and the mounting base 5 are connected by a snap-fit ​​mechanism, a gap 6 exists between the side wall of the mounting component 12 and the inner wall of the recess 51. When the vertical high-temperature sulfuric acid pump is turned on, the high temperature of the sulfuric acid medium causes the pump body components to heat up rapidly through heat conduction. At this time, the mounting and fixing components expand horizontally due to the heat. The gap 6 provides a certain space for the horizontal thermal expansion of the bolts 2 and the mounting component 12, preventing damage caused by mutual compression between the thermally expanding components, thereby affecting the service life of the vertical high-temperature sulfuric acid pump.

[0023] like Figs. 1-4 As shown, in this embodiment, the inner wall of the mounting component 12 is provided with threads that match the bolt 2, and the bottom inner wall of the recess 51 is also provided with threads that match the bolt 2. The bolt 2 can be screwed out of the mounting component 12 and subsequently threadedly connected to the recess 51. A spring washer 3 and a flat washer 4 are provided between the bolt 2 and the mounting base 5. The flat washer 4 is in contact with the mounting surface 13 of the sulfuric acid pump base 1, and the spring washer 3 is located between the bolt 2 and the flat washer 4. In use, after the snap-fit ​​assembly groove 121 is snapped into the snap-fit ​​base 53, the bolt 2 is screwed into the mounting component 12 along the threads in its bolt hole 11, and then screwed into the threads of the recess 51 for secondary reinforcement. The flat washer 4 can increase the contact area to distribute the preload of the fastener, reduce the pressure on the connecting parts, avoid damage caused by excessive local stress, and also reduce the noise generated by vibration when the vertical high-temperature sulfuric acid pump is working. The spring washer 3 can generate a continuous elastic force through its own elastic deformation. This elastic force increases the friction between the threads, thereby preventing the bolt from loosening. Through the cooperation of the spring washer 3 and the flat washer 4, shocks and vibrations can be absorbed, the clamping force at the connection can be maintained, and the stability of the threaded connection can be enhanced.

[0024] The gap formed by the snap-fit ​​connection between the mounting component and the mounting base provides a certain space for the bolt and the mounting component during thermal expansion and contraction, preventing the bolt and the mounting component from being squeezed and damaged, thus affecting the service life of the vertical high-temperature sulfuric acid pump. The flat washer and spring washer located below the bolt can absorb impact and vibration while maintaining the clamping force at the connection. In addition, the spring at the bottom of the recess can also play a certain role in vibration reduction when the vertical high-temperature sulfuric acid pump is working.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
