Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde solution production, in particular to a rotary liquid discharge device for a formaldehyde solution production tank. Background Art

[0002] Formaldehyde solution is a solution of formaldehyde dissolved in water, commonly found in industry and laboratories. Formaldehyde is a colorless gas with a strong, pungent odor and is widely used in the manufacture of resins, disinfectants, and preservatives. The rotary tapping device used in formaldehyde solution production is a device used to remove formaldehyde solution from storage tanks.

[0003] Existing formaldehyde solution is usually placed inside a formaldehyde solution tank for storage and processing during production, and is discharged through a drain pipe when needed. However, the outlet pipe of the formaldehyde solution tank is usually an external design. When the formaldehyde tank is placed or transported, dust and impurities can easily enter and adhere to the inside of the outlet pipe. As a result, when the formaldehyde solution is used, the collected formaldehyde solution will be mixed with a certain amount of dust and impurities, affecting the use effect of the formaldehyde solution. Utility Model Content

[0004] The purpose of the utility model is to provide a rotary liquid discharge device for a formaldehyde solution production tank, so as to solve the problem in the prior art that the liquid discharge pipe of the formaldehyde solution tank is usually designed to be external, and dust and impurities are easily entered and adhered to the inner side of the liquid discharge pipe when the formaldehyde tank is placed or transported, resulting in the collected formaldehyde solution being mixed with a certain amount of dust and impurities during use, thereby affecting the use effect of the formaldehyde solution.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotary liquid discharge device for a formaldehyde solution production tank, comprising a formaldehyde solution tank, a base fixedly installed at the bottom of the formaldehyde solution tank, a liquid storage pipe fixedly installed at the top of the formaldehyde solution tank, a liquid discharge pipe fixedly installed on one side of the formaldehyde solution tank, a fixed ring fixedly installed at the middle position of the liquid discharge pipe, a rotating shaft rotatably installed on the inner side of the fixed ring, a circular plate fixedly installed on the outer side of the rotating shaft, a dustproof structure is provided on the outer side of the liquid discharge pipe, the dustproof structure includes a second U-shaped seat, the second U-shaped seat is fixedly installed on the outer side of the liquid discharge pipe, one end of the rotating shaft passes through the fixing ring and the second U-shaped seat and is rotatably connected to the fixing ring and the second U-shaped seat, and one end of the rotating shaft is fixedly installed with a No. 1 bevel gear.

[0006] Preferably, two No. 2 fixing seats are fixedly installed on the top of the second U-shaped seat, and a No. 1 connecting shaft is rotatably installed between the two No. 2 fixing seats. A No. 2 bevel gear is fixedly installed on the outer side of the No. 1 connecting shaft, and the No. 1 bevel gear and the No. 2 bevel gear are meshed and connected.

[0007] Preferably, a No. 2 connecting shaft is rotatably installed between the two No. 2 fixing seats, an L-shaped plate is fixedly installed on the outer side of the No. 2 connecting shaft, a dust cover is fixedly installed on one side of the L-shaped plate, and the size of the dust cover is adaptable to the liquid outlet pipe.

[0008] Preferably, both ends of the No. 1 connecting shaft pass through two No. 2 fixing seats and are fixedly installed with a No. 1 gear, and both ends of the No. 2 connecting shaft pass through two No. 2 fixing seats and are fixedly installed with a No. 2 gear, and the two No. 1 gears are respectively meshed and connected with the two No. 2 gears.

[0009] Preferably, a limit plate is fixedly installed between the two No. 2 fixing seats, and the limit plate is arranged at the rear position of the L-shaped plate. The limit plate can limit the rotation angle of the dust cover and the circular plate.

At this time, the opening of the circular plate is the largest and the liquid output is also the largest. When the dust cover covers the liquid outlet pipe, it will not be able to continue to move. At this time, the circular plate will block the liquid outlet pipe, thereby sealing the liquid outlet pipe.

[0010] Preferably, a first U-shaped seat is fixedly installed on the outer side of the liquid outlet pipe, the other end of the rotating shaft passes through the fixing ring and the first U-shaped seat and is rotatably connected to the fixing ring and the first U-shaped seat, and a worm gear is fixedly installed on the other end of the rotating shaft.
