Description

Technical Field

[0001] This utility model relates to the field of slurry pump technology, and in particular to a mechanical seal water tank installation device for slurry pumps. Background Technology

[0002] A slurry pump is an industrial centrifugal pump. It is mainly suitable for conveying coarse-particle, high-concentration slurries. It is widely used in industries such as metallurgy, mining, coal, power, building materials, and environmental protection.

[0003] When slurry pumps operate under harsh conditions and have difficulty supplying water, low-pressure self-circulating mechanical seals are used. This type of mechanical seal is equipped with a water tank and installed on the rear pump casing. Although the installation method is convenient, it affects maintenance, disassembly, and hoisting. Furthermore, when the water tank is damaged or needs to be replaced, the traditional water tank fixing method is inconvenient to disassemble and assemble. Therefore, a mechanical seal water tank installation device for slurry pumps that can solve the above problems is provided. Utility Model Content

[0004] The technical problem this invention aims to solve is to address the aforementioned technical deficiencies by providing a mechanical seal water tank installation device for slurry pumps. This structure facilitates maintenance and pump body lifting, allows for quick and easy disassembly and assembly of the water tank, and makes it more convenient to use.

[0005] The technical solution adopted by this utility model is as follows: a mechanical seal water tank installation device for a slurry pump is provided, including a base and a pump body installed on the base. The device is characterized in that: a bracket that cooperates with the base is provided on one side of the pump body, a water tank is provided on the bracket, and connecting devices are provided at both the front and rear ends of the bracket; the front connecting device includes a connecting plate fixed to the upper end of the bracket, a limiting plate corresponding to the connecting plate is provided on the lower side of the front end of the water tank, and a connecting groove is provided on both the connecting plate and the limiting plate; a slider is slidably connected to the lower end of the connecting plate along the direction of the connecting groove, and a nut is slidably connected to the slider; the rear connecting device and the front connecting device are symmetrical and have the same structure.

[0006] To further optimize this technical solution, a mechanical seal water tank installation device for a slurry pump also includes bolts, the threaded end of which passes through two connecting grooves and is threadedly connected to a nut.

[0007] To further optimize this technical solution, an "L"-shaped slide rail is fixedly connected to the connecting plate of a mechanical seal water tank installation device for a slurry pump, and the slider is slidably connected to the slide rail.

[0008] To further optimize this technical solution, an "L"-shaped limiting rod is fixedly connected to the connecting plate of a mechanical seal water tank installation device for a slurry pump. The limiting rod is located below the nut, and a gap is left between the upper end of the slider and the lower end of the connecting plate.

[0009] To further optimize this technical solution, the upper end of the bolt of the mechanical seal water tank installation device for a slurry pump is circular, and the connecting plate has a groove that mates with the bolt; at the groove, the connecting plate has a rounded corner corresponding to the bolt.

[0010] To further optimize this technical solution, a mechanical seal water tank installation device for a slurry pump is provided with interlocking anti-slip teeth between the connecting plate and the limiting plate.

[0011] To further optimize this technical solution, a connection hole is provided at both the bracket and the base of the mechanical seal water tank installation device for a slurry pump.

[0012] Compared with traditional mechanical seal water tank installation devices, the advantages of this utility model are as follows:

[0013] 1. The fit between the bracket, connecting hole, base, connecting plate, limit plate, connecting groove, water tank, and pump body is such that neither the water tank nor the bracket obstructs the pump body, thus not affecting the maintenance and disassembly of the pump body, nor affecting the lifting of the pump body by the hoisting rope, making it convenient for maintenance and lifting of the pump body;

[0014] 2. The combination of water tank, limit plate, bracket, connecting plate, connecting groove, bolt, nut, limit plate, slider, and slide rail facilitates quick fixing and disassembly of the water tank. During installation, one hand is not needed to hold the nut, making it more convenient to use.

[0015] 3. The slot design facilitates better fixation and limiting; the anti-slip teeth increase friction to prevent water tank displacement. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-9 As shown, a mechanical seal water tank installation device for a slurry pump includes a base 1 and a pump body 2 mounted on the base 1. The device is characterized by: a bracket 3 cooperating with the base 1 is provided on one side of the pump body 2; a water tank 4 is mounted on the bracket 3; and connecting devices are provided at both the front and rear ends of the bracket 3. The front connecting device includes a connecting plate 5 fixed to the upper end of the bracket 3; a limiting plate 6 corresponding to the connecting plate 5 is provided on the lower side of the front end of the water tank 4; both the connecting plate 5 and the limiting plate 6 have connecting grooves 7; a slider 8 is slidably connected to the lower end of the connecting plate 5 along the direction of the connecting groove 7; and a nut 9 is slidably connected to the slider 8. The rear connecting device and the front connecting device are symmetrical and have the same structure. It also includes screws. Bolt 10 has its threaded end passing through two connecting grooves 7 and then threadedly connected to nut 9; an "L"-shaped slide rail 11 is fixedly connected to the connecting plate 5, and slider 8 is slidably connected to the slide rail 11; an "L"-shaped limiting rod 12 is fixedly connected to the connecting plate 5, and the limiting rod 12 is located below nut 9, with a gap between the upper end of slider 8 and the lower end of connecting plate 5; the upper end of bolt 10 is round, and a groove 13 is opened on the connecting plate 5 to mate with bolt 10; at the connecting groove 7, the connecting plate 5 has a rounded corner 14 corresponding to bolt 10; anti-slip teeth 15 that mesh with each other are provided between connecting plate 5 and limiting plate 6; connecting holes 16 are provided at both bracket 3 and base 1.

[0028] The specific structural positions of connecting plate 5 and limiting plate 6 are as follows: Figure 4 As shown;

[0029] In use, bracket 3 is connected to base 1 through connecting hole 16, bracket 3 is connected to water tank 4 through connecting groove 7 on connecting plate 5 and limiting plate 6, and water tank 4 is connected to pump body 2 through hose. Neither water tank 4 nor bracket 3 obstructs pump body 2, so it does not affect maintenance and disassembly of pump body 2. When pump body 2 needs to be lifted, the position of water tank 4 will not affect the lifting rope to lift pump body 2, which is convenient for maintenance and lifting of pump body 2.

[0030] The connection device is set up by placing the water tank 4 and the limiting plate 6 on the bracket 3 and the connecting plate 5, aligning the connecting grooves 7, and then connecting them to the nut 9 via bolt 10 threaded connection. Rotating bolt 10 connects the nut 9 and bolt 10, at which point it will... Figure 6 As shown, the connecting plate 5 and the limiting plate 6 are fixed together by bolt 10 and connecting groove 7, thereby fixing the water tank 4 to the bracket 3. The sliding limit of nut 9 and slider 8 allows for easy rotation without manually holding nut 9; simply rotating bolt 10 connects them, making it more convenient. When replacing or disassembling the water tank 4, rotating bolt 10 in the opposite direction releases the bolt 10 and nut 9 from clamping the connecting plate 5 and limiting plate 6, thus moving bolt 10 and nut 9 and causing slider 8 to slide, moving it to the desired position. Figure 7 As shown, bolt 10 no longer limits the limiting plate 6 on water tank 4, so water tank 4 can be removed without unscrewing the entire bolt 10 from nut 9, making it more convenient to use. Moreover, slider 8 will not detach due to the limiting of "L"-shaped slide rail 11, making it easy to fix water tank 4 again. This facilitates quick fixing and quick disassembly of water tank 4, and installation does not require holding nut 9 with one hand, making it more convenient to use.

[0031] The slot 13 is designed for better fixation and limiting; the anti-slip teeth 15 are designed to increase friction and prevent the water tank 4 from shifting.

[0032] In this utility model, the pump body 2 is a horizontal slurry pump.
