Description

Technical Field

[0001] This invention relates to the field of liquid extraction tools, and more specifically, to a liquid pouring device for storage tanks. Background Technology

[0002] In industrial installations, atmospheric pressure storage tanks are a common and widely used piece of equipment in both production and daily life. These tanks can store various liquid substances such as water, acids, liquid alkalis, liquid ammonia, oils, and organic solvents. During the actual storage of liquid substances in these tanks, prolonged use or storage of substances can lead to corrosion and perforation, requiring maintenance. To provide suitable conditions for maintenance, the solution in the tank must be emptied or pumped out beforehand. However, during long-term storage of liquid substances, some sediment may form at the bottom of the tank. If a small amount of air leaks into the tank, or if gas is introduced to maintain internal pressure as the material level decreases, carbon dioxide and calcium ions in the solution may combine to form precipitates. Therefore, even using a traditional pump to completely empty the solution from the tank's outlet may leave some sediment at the bottom, resulting in incomplete cleaning. Summary of the Invention

[0003] The purpose of this invention is to provide a liquid-removing device for atmospheric pressure storage tanks that can remove the solution and bottom impurities from the storage tank more thoroughly.

[0004] The embodiments of the present invention are achieved through the following technical solution: a liquid transfer device for an atmospheric pressure storage tank, comprising a storage tank body, a pneumatic diaphragm pump, and a transfer tank. The pneumatic diaphragm pump has a first connecting pipe at its front end and a second connecting pipe at its rear end for communicating with the transfer tank. The front end of the first connecting pipe is provided with a sleeve assembly and a connecting assembly in sequence. The sleeve assembly includes a slag suction pipe, a rotating cylinder, and multiple connecting sleeve links that are hinged end to end in sequence. The rotating cylinder is fixedly connected to the rear end of the connecting sleeve links. The surface of the slag suction pipe has multiple slag suction holes. The connecting sleeve links are hollow structures. The slag suction pipe passes through the rotating cylinder and the connecting sleeve links in sequence. The rear end of the slag suction pipe is connected to the first connecting pipe. The connecting assembly includes a docking flange. The docking flange is detachably connected to the bottom liquid outlet of the storage tank body, and the rotating cylinder is rotatably connected to the docking flange.

[0005] Furthermore, the connecting assembly also includes a bearing and a first seal. The bearing is sleeved on the outside of the rotating drum, and the outside of the bearing is engaged in the mating flange. The tail of the rotating drum is fitted with a toothed ring, which meshes with a drive gear driven by a motor, thereby driving the tube sleeve assembly to rotate.

[0006] Furthermore, the connecting assembly includes a support platform and a lifter, one end of which is connected to the support platform, and the support platform is used to support the rotating drum and the drive gear.

[0007] Furthermore, windows are provided on both sides of the connecting sleeve link, the windows are on the same side as the hinge point of the connecting sleeve link, and the slag suction hole faces the window and corresponds to it.

[0008] Furthermore, the outer surface of the connecting chain link is equipped with ball bearings that roll in contact with the inner wall of the tank body, and the ball bearings are positioned close to the window.

[0009] Furthermore, a filter is installed on the first connecting pipe, and the filter is located at the front end of the pneumatic diaphragm pump.

[0010] Furthermore, it also includes a trolley, on which the pneumatic diaphragm pump and the transfer tank are mounted, and a handrail is provided at the rear of the trolley.

[0011] Furthermore, the inner wall of the rotating drum is provided with a second sealing element, which is used to contact the rotating drum.

[0012] Furthermore, both the first connecting pipe and the second connecting pipe are made of steel wire reinforced flexible hose.

[0013] The technical solution of this invention has at least the following advantages and beneficial effects: Compared with the prior art, this invention extends the sleeve assembly from the bottom outlet of the storage tank body. The connecting sleeve chain and the sludge suction pipe extending into the storage tank body extend radially along the middle of the storage tank body. The motor drives the drive gear to rotate, and in turn drives the rotating drum and the sleeve assembly to rotate. The pneumatic diaphragm pump starts to suck the solution and impurities in the storage tank body into the transfer tank for temporary storage. Because the connecting sleeve chain and the sludge suction pipe sweep in a pointer-like manner at the bottom of the storage tank body with the outlet as the center, the sediment at the bottom can be fully drawn into the sludge suction hole for discharge, resulting in a better and more thorough cleaning effect and less sediment residue.

[0025] Example

[0026] The following description, in conjunction with specific embodiments, provides further details. Figures 1-6As shown, this embodiment is a liquid transfer device for an atmospheric pressure storage tank, including a storage tank body 1, a pneumatic diaphragm pump 2, and a transfer tank 3. The pneumatic diaphragm pump 2 has a first connecting pipe 5 at its front end and a second connecting pipe 4 at its rear end for communication with the transfer tank 3. The front end of the first connecting pipe 5 is provided with a pipe sleeve assembly 7 and a connecting assembly 8 in sequence. The pipe sleeve assembly 7 includes a slag suction pipe 72, a rotating cylinder 73, and multiple connecting sleeve links 71 that are hinged end to end in sequence. The rotating cylinder 73 is fixedly connected to the rear end of the connecting sleeve links 71. The surface of the slag suction pipe 72 has multiple slag suction holes 721. The connecting sleeve links 71 are... The structure is hollow, with the suction pipe 72 passing through the rotating drum 73 and the connecting chain link 71 in sequence. The tail end of the suction pipe 72 is connected to the first connecting pipe 5. The connecting assembly 8 includes a docking flange 81, which is detachably connected to the bottom liquid outlet of the storage tank body 1, and the rotating drum 73 is rotatably connected to the docking flange 81. Specifically, the storage tank body 1 in this invention has a medium volume and a cylindrical structure with a diameter between 5 and 15 meters. The pneumatic diaphragm pump 2 uses compressed air as its power source, and the pressure requirement of the compressed air is 0.2-0.6 MPa. The rotating drum 73 can reach the docking flange 81. The axial direction of tank 1 moves back and forth to a certain extent. During use, the suction pipe 72 is inserted into the cavity formed by multiple connecting chain links 71. The suction pipe 72, along with the connecting chain links 71, extends from the liquid outlet at the bottom of the storage tank body 1. Due to gravity and the relatively soft material of the suction pipe 72, the suction pipe 72 and the connecting chain links 71 will adhere to the bottom of the storage tank body 1 and extend radially to contact the inner wall surface of the storage tank body 1. The docking flange 81 is connected to the liquid outlet at the bottom of the storage tank body 1 by screws. The motor is started to drive the drive gear 84 to rotate, thereby driving the rotating drum 7 in sequence. 3. The connecting chain link 71 and the slag suction pipe 72 rotate, and the slag suction pipe 72 sweeps at the bottom of the storage tank body 1 in a pointer manner. Then, the pneumatic diaphragm pump 2 is started to suck the mixture of solution and precipitate in the storage tank body 1 into the slag suction pipe 72, the first connecting pipe 5 and the second connecting pipe 4 through the slag suction hole 721 and put it into the transfer tank 3 for temporary storage. This can remove the precipitate at the bottom more cleanly and thoroughly. It is worth noting that the volume of the transfer tank 3 is usually smaller than that of the storage tank body 1. Therefore, it may not be possible to transfer the solution completely in one go. It is necessary to transfer the solution in the transfer tank 3 into another storage tank in several batches.

[0027] In this embodiment, the connecting assembly 8 further includes a bearing 83 and a first seal 82. The bearing 83 is sleeved on the outside of the rotating drum 73, and the outside of the bearing 83 is engaged in the docking flange 81. The tail of the rotating drum 73 is fitted with a toothed ring 731, which meshes with a drive gear 84 driven by a motor. The drive gear 84 drives the tube sleeve assembly 7 to rotate. Specifically, the first seal 82 improves the sealing between the rotating drum 73 and the docking flange 81 to prevent solution leakage during the pumping process. In addition, when the motor drives the toothed ring 731 and the rotating drum 73 to rotate via the drive gear 84, the motor can make the rotating drum 73 rotate one revolution clockwise and then one revolution counterclockwise, which can effectively prevent the slag suction pipe 72 from being kinked and damaged.

[0028] Reference Figure 1 and Figure 2 As shown, the connecting component 8 in this embodiment includes a support platform 85 and a lifter 86. One end of the lifter 86 is connected to the support platform 85. The support platform 85 is used to support the rotating drum 73 and the drive gear 84. Specifically, the motor is mounted on the support platform 85, and one end of the first connecting pipe 5 also passes through the support platform 85. The lifter 86 can easily lift the docking flange 81, the rotating drum 73, and the slag suction pipe 72. The lifter 86 gradually rises until the docking flange 81 abuts against the liquid outlet of the storage tank body 1 and the screws are tightened.

[0029] Reference Figure 4 and Figure 5 As shown, in this embodiment, windows 711 are provided on both sides of the connecting sleeve link 71. The windows 711 and the hinge point of the connecting sleeve link 71 are on the same side, and the slag suction hole 721 faces the window 711 and corresponds to it. Specifically, the connecting sleeve link 71 has a cuboid structure with windows 711 on both sides. The windows 711 facilitate the exposure of the slag suction hole 721. Thus, during the rotation of the connecting sleeve link 71 and the slag suction tube 72, the opening direction of the slag suction hole 721 is consistent with the tangential direction of the rotation, and the precipitate and solution can be more easily sucked into the slag suction hole 721.

[0030] Reference Figure 4 and Figure 5 As shown, in this embodiment, the outer surface of the connecting sleeve link 71 is equipped with a ball bearing 712 that rolls in contact with the inner wall of the tank body 1, and the ball bearing 712 is arranged close to the window 711; specifically, the ball bearing 712 contacts the bottom of the tank body 1, which can reduce the friction between the suction pipe 72 and the bottom of the tank body 1 during the pointer-type rotation.

[0031] Reference Figure 1 As shown, a filter 6 is installed on the first connecting pipe 5, and the filter 6 is located at the front end of the pneumatic diaphragm pump 2; specifically, by setting this filter 6, the precipitates and impurities in the solution extracted from the storage tank body 1 are removed, so that the solution with relatively higher purity enters the transfer tank 3 for storage.

[0032] This embodiment also includes a trolley 9, on which the pneumatic diaphragm pump 2 and the transfer tank 3 are mounted. A handle is provided at the rear of the trolley 9. Specifically, this mechanism is installed on the trolley 9 to facilitate transfer and movement and improve the flexibility of use.

[0033] In addition, the inner wall of the rotating drum 73 is provided with a second seal 732, which is used to contact the rotating drum 73; specifically, the slag suction pipe 72 passes through the rotating drum 73, and the second seal 732 is provided to improve the sealing between the two and prevent the solution from flowing out from the gap.

[0034] More preferably, in this embodiment, both the first connecting pipe 5 and the second connecting pipe 4 are made of steel wire reinforced hoses to ensure the strength of the inlet and outlet pipelines and improve their service life. The steel wire reinforced hoses have excellent acid and alkali resistance, oil resistance and elasticity, and are very suitable for use in pumping liquid from atmospheric pressure storage tanks.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
