Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] In the present application, the terms "mount", "set", "provided with", "connect", "connected" should be understood broadly. For example, it can be fixed connection, detachable connection, or integral configuration; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate media, or the internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and configurations may be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "a plurality of" is two or more.

[0038] The technical solutions of the present application will be further described below in combination with specific embodiments and drawings.

[0039] Please refer to Figure 1 The embodiment of the present application provides a liquid sulfur pump 1, which comprises a base 11, a liquid subassembly 12 and a filter screen cylinder 13. The base 11 has a bottom surface 111, and the base 11 is configured to be capable of being mounted to an opening of a work tank. The liquid subassembly 12 comprises a machine pump and an impeller, the machine pump is connected to the bottom surface 111, and the impeller is connected to the machine pump and located at an end of the machine pump away from the base 11. The filter screen cylinder 13 is connected to the base 11, and the filter screen cylinder 13 has a containing cavity 131 for containing the liquid subassembly 12. When the base 11 is mounted to the opening of the work tank, the liquid subassembly 12 and the filter screen cylinder 13 are located in the work tank.

[0040] In some embodiments, the filter screen cylinder 13 is connected to the bottom surface 111.

[0041] In the embodiment, when the liquid sulfur pump 1 is assembled to the opening of the work tank, the base 11 is mounted to the opening of the work tank, and the liquid subassembly 12 and the filter screen cylinder 13 extend into the work tank through the opening. Since the liquid subassembly 12 is entirely located in the containing cavity 131 of the filter screen cylinder 13, even if the liquid level in the work tank rises, the solid impurity particles on the liquid surface are blocked outside the containing cavity 131 by the filter screen cylinder 13, so that the solid impurity particles on the liquid surface can be prevented from entering the machine pump, thereby preventing the pump body from being worn or blocked and even causing the machine pump to be stuck, so that the effect of protecting the machine pump is achieved, the frequency of maintenance or replacement of the machine pump is reduced, and the continuous and stable operation of the machine pump is ensured.

[0042] It should be noted that the work tank has a side wall surrounding the opening, and the work tank also has an upper surface connected to the side wall, and in addition, the base 11 also has a side surface connected to the bottom surface 111. When the base 11 is mounted to the opening of the work tank, the side surface of the base 11 can be matched with the side wall surrounding the opening of the work tank, or the bottom surface 111 of the base 11 can be matched with the upper surface of the work tank.

[0043] Please continue to refer to Figure 1 In some embodiments, the filter screen cylinder 13 is connected to the bottom surface 111.

[0044] Connecting the filter screen cylinder 13 to the bottom surface 111 can enhance the stability of the filter screen cylinder 13. This connection mode forms a relatively stable whole between the filter screen cylinder 13 and the base 11, so as to avoid the movement or inclination of the filter screen cylinder 13 caused by the vibration of the liquid sulfur pump 1 or external force during the work process.

[0045] In other embodiments, the filter screen cylinder 13 can be connected to the side surface of the base 11.

[0046] Please refer to Figure 2In some embodiments, the liquid sulfur pump 1 further comprises a connecting member 14, and the filter screen cylinder 13 is provided with a hanging ear 15, and the connecting member 14 is arranged through the base 11 and connected to the hanging ear 15 when the base 11 is installed in the opening of the working pool.

[0047] The connecting member 14 tightly connects the hanging ear 15 of the filter screen cylinder 13 and the base 11, which can ensure the stability of the filter screen cylinder 13 during the operation of the liquid sulfur pump 1, and helps to prevent the filter screen cylinder 13 from being displaced or falling off due to liquid flow impact or vibration, thereby ensuring the normal operation and filtering effect of the liquid sulfur pump 1.

[0048] In other embodiments, the hanging ear 15 can also be clamped to the base 11.

[0049] Please refer to Figure 2 and Figure 3 In some embodiments, the connecting member 14 is a bolt, the base 11 is provided with a first hole 112, and the hanging ear 15 is provided with a second hole 151, and the bolt is arranged through the first hole 112 and the second hole 151 when the base 11 is installed in the opening of the working pool.

[0050] The bolt arranged through the first hole 112 and the second hole 151 can reduce the difficulty of fixing the filter screen cylinder 13 and the base 11, and does not need to be operated complicatedly, thereby greatly improving the installation efficiency. In addition, the bolt arranged through the first hole 112 and the second hole 151 tightly connects the filter screen cylinder 13 and the base 11 together to form a stable overall structure, which can withstand a large liquid flow impact and vibration, and ensure that the filter screen cylinder 13 will not be loose or fall off during the operation.

[0051] It can be understood that when the bolt is arranged through the first hole 112 and the second hole 151, the bolt can be threadedly connected with only the first hole 112, or only the second hole 151, or both the first hole 112 and the second hole 151, which is not limited herein.

[0052] In other embodiments, the connecting member 14 can also be a buckle, and the hanging ear 15 is clamped to the base 11 through the buckle.

[0053] Please refer to Figure 4 and Figure 5 In some embodiments, the first hole 112 has a smaller diameter than the second hole 151. The base 11 and the opening of the working pool are both circular structures, and the diameter of the base 11 is greater than that of the opening of the working pool. When the base 11 is installed in the opening of the working pool, the first hole 112 is threadedly connected with the bolt, and the hanging ear 15 is clamped between the bottom surface 111 of the base 11 and the upper surface of the opening of the working pool.

[0054] The first hole 112 has a smaller diameter than the second hole 151. The bolt is threadedly connected to the first hole 112, and when the bolt is arranged in the second hole 151, a gap is formed between the outer surface of the bolt and the inner wall of the second hole 151.

[0055] The work tank has a side wall surrounding the opening. The upper surface of the work tank surrounding the opening refers to the upper surface of the side wall of the work tank.

[0056] In the installation process of the liquid sulfur pump 1, the filter screen cylinder 13 is first arranged in the work tank through the opening of the work tank until the lower surface of the lug 15 abuts against the upper surface of the work tank. Then, the liquid lower part 12 is arranged in the work tank through the opening of the work tank until the bottom surface 111 of the base 11 abuts against the upper surface of the lug 15, so that the lug 15 is clamped between the bottom surface 111 of the base 11 and the upper surface of the work tank. Then, the bolt is arranged in the first hole 112 and threadedly connected to the first hole 112, and the bolt is arranged in the second hole 151. The bolt applies a clamping force to the lug 15 through the base 11, so as to fix the filter screen cylinder 13.

[0057] It can be understood that the bolt is threadedly connected to the first hole 112 to form a stable mechanical locking, so that the connection between the filter screen cylinder 13 and the base 11 is more reliable and can withstand greater tension and shear force, thereby ensuring the stable connection between the filter screen cylinder 13 and the base 11.

[0058] In other embodiments, the diameter of the first hole 112 can be equal to the diameter of the second hole 151, and the bolt can be threadedly connected to both the first hole 112 and the second hole 151.

[0059] In some embodiments, the diameter of the second hole 151 is 30 mm.

[0060] In the embodiment, the diameter of the first hole 112 is less than 30 mm.

[0061] In other embodiments, the diameter of the second hole 151 can be greater than 30 mm.

[0062] Please refer to Figure 3 and Figure 5 In some embodiments, the lug 15 includes a first plate body 152 and a second plate body 153 connected to each other. The first plate body 152 extends in parallel with the axial direction of the filter screen cylinder 13, and the second plate body 153 extends in parallel with the radial direction of the filter screen cylinder 13. The first plate body 152 is connected to the inner wall of the filter screen cylinder 13, and the second plate body 153 is away from the first plate body 152 and away from the central axis of the filter screen cylinder 13.

[0063] The first plate body 152 is axially parallel to the filter screen cylinder 13 and is connected to the inner wall of the filter screen cylinder 13, thereby providing stable axial support for the filter screen cylinder 13, which helps to reduce the vibration and deformation of the filter screen cylinder 13 during the flow of liquid sulfur, thereby ensuring the stability and durability of the filtering efficiency. The second plate body 153 is radially parallel to the filter screen cylinder 13 and extends away from the central axis of the filter screen cylinder 13, thereby providing effective radial fixation for the filter screen cylinder 13, which helps to prevent displacement or rotation of the filter screen cylinder 13 during the flow of liquid sulfur, thereby ensuring correct alignment and close connection with the pump body or other components.

[0064] In other embodiments, the first plate body 152 can also be connected to the outer wall of the filter screen cylinder 13.

[0065] In some embodiments, the number of hanging ears 15 is eight.

[0066] In some embodiments, the eight hanging ears 15 can be evenly distributed, which can ensure more uniform support and fixation of the filter screen cylinder 13, thereby reducing local stress concentration of the filter screen cylinder 13 and improving the stability and durability of the overall structure.

[0067] In other embodiments, the number of hanging ears 15 can be four or six, which is not limited herein.

[0068] In some embodiments, the filter screen cylinder is provided with a plurality of mesh holes, and the pore size of the plurality of mesh holes is 1mm.

[0069] The 1mm pore size mesh hole can effectively block most solid impurity particles, thereby preventing solid impurity particles from passing through the mesh hole and avoiding pump jamming caused by solid impurity particles, which helps to improve the operation stability and reliability of the liquid sulfur pump 1.

[0070] In other embodiments, the pore size of the mesh hole can be less than 1mm.

[0071] In some embodiments, the height of the filter screen cylinder 13 is 6100mm, the outer diameter of the filter screen cylinder 13 is 820mm, and the inner diameter of the filter screen cylinder 13 is 818mm.

[0072] The height of the filter screen cylinder 13 is 6100mm, and the inner diameter of the filter screen cylinder 13 is 818mm, so that the filter screen cylinder 13 has a large filtering area to filter more solid impurity particles, thereby improving the filtering efficiency.

[0073] The outer diameter of the filter screen cylinder 13 is 820mm, and the inner diameter of the filter screen cylinder 13 is 818mm, i.e. the thickness of the filter screen cylinder 13 is 2mm, which can make the filter screen cylinder 13 not easy to deform.

[0074] In some other embodiments, the outer diameter of the filter screen cylinder 13 can be greater than 820 mm.

[0075] Although the present application has been described with reference to the preferred embodiments, various modifications and changes can be made thereto without departing from the scope of the present application. In particular, the technical features mentioned in each of the embodiments can be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
