Description

Technical Field

[0001] The utility model relates to a foam-liquid separator which is used for eliminating foam components in liquid. Background Art

[0002] At present, in many process occasions involving the preparation of liquid products or reactions involving liquids, foam will inevitably occur in the liquid due to process reasons. The presence of these foams will affect the product quality or subsequent processes, so they must be eliminated. Our company has developed and applied for Chinese patent ZL2023202389625 "degassing mechanism" and Chinese patent ZL202320238995X "degassing system" to eliminate foam. However, the above-mentioned specialized equipment is expensive and is an independent equipment. During use, the original production line layout needs to be improved, which is not conducive to upgrading the existing production line. Therefore, there is an urgent need for a simple structure and low-cost device to achieve bubble-liquid separation. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a bubble-liquid separator with simple structure and low cost.

[0004] The purpose of the utility model is achieved in this way:

[0005] A bubble-liquid separator comprises a cylinder, a vacuum port is arranged on the cylinder, a liquid discharge port is arranged at the bottom of the cylinder, a rotor is installed at the upper part of the cylinder, an upper baffle is arranged between the upper part of the rotor and the vacuum port, a liquid inlet pipe is inserted into the cylinder from the bottom of the cylinder upward, and a lower baffle is mounted on the top of the liquid inlet pipe located in the cylinder, and the lower baffle is located at the lower part of the rotor.

[0006] Preferably, a motor is installed on the top outer wall of the cylinder, and the driving shaft of the motor is inserted downward into the cylinder and passes through the upper baffle to drive the rotor to rotate.

[0007] Preferably, there is an annular slit between the outer edge of the upper baffle and the inner wall of the cylinder.

[0008] Preferably, the rotor is an impeller structure, which includes a central shaft connected by a motor drive shaft, and a plurality of impellers are arranged on the central shaft.

[0009] Preferably, the open end of the liquid inlet pipe is located directly below the central axis of the rotor.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model can conveniently install the cylinder body on a device such as a reaction tank where foam elimination is required, and then, under the action of negative pressure, insert a liquid inlet pipe into the tank body to extract liquid with foam, and the foam is eliminated in the process of throwing the liquid toward the cylinder wall through the rotor in the form of an impeller structure, and the foam will be accumulated in the cylinder body and can be discharged regularly. The overall structure is simple, the operation is convenient, and there is no need to change the original production line layout, which is conducive to the market promotion of this product. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a structural schematic diagram of a novel bubble-liquid separator.

[0013] in:

[0014] Cylinder 1, motor 2, rotor 3, lower baffle 4, upper baffle 5, liquid inlet pipe 6;

[0015] Vacuum port 1.1, drain port 1.2. DETAILED DESCRIPTION

[0016] See also Figure 1 The utility model relates to a bubble-liquid separator, which comprises a barrel 1 which can be installed on a reaction tank, a vacuum port 1.1 is arranged on the top of the barrel 1 for performing vacuum treatment so as to form a negative pressure environment in the barrel 1, a liquid discharge port 1.2 is arranged on the bottom of the barrel 1, a motor 2 is installed on the top outer wall of the barrel 1, a driving shaft of the motor 2 is inserted downward into the barrel 1 to drive a rotor 3 to rotate, the rotor 3 is located at the upper part of the barrel 1, and the rotor 3 is an impeller structure, and the rotor 3 is located at the upper part of the barrel 1.

[0017] An upper baffle 5 is provided on the upper part of the rotor 3, and the upper baffle 5 is located between the rotor 3 and the vacuum port 1.1. The upper baffle 5 prevents the liquid broken by the rotor 3 during operation from being directly drawn out through the vacuum port 1.1. Therefore, the upper baffle 5 is a disc-shaped structure, and its outer diameter matches the inner diameter of the cylinder 1, so that only an annular slit is left between the upper baffle 5 and the inner wall of the cylinder 1 to ensure the air path is connected.

[0018] The lower part of the rotor 3 is provided with a lower baffle 4, which is used to prevent the liquid discharged from the liquid inlet pipe 6 from directly flowing back downward, and the outer diameter of the lower baffle 4 of the disc structure is consistent with the outer diameter of the rotor 3. Preferably, the rotor 3 is installed in a volute of a tubular structure (the tubular structure can be a round tube or a square tube structure), and the volute of the tubular structure is arranged horizontally. At this time, the volute actually plays the role of the lower baffle 4, and the upper baffle 5 is located above the volute to cover the entire volute range; the motor 2 passes through the upper baffle 5 and the volute and is inserted into the volute to drive the rotor 3 to rotate.

[0019] The liquid inlet pipe 6 is inserted upward from the top of the cylinder 1, and the top open end of the liquid inlet pipe 6 is connected to the lower baffle 4 (when the rotor 3 is located in the volute, the liquid inlet pipe 6 penetrates the shell wall of the volute located at the lower part), so that the liquid with foam is introduced into the rotor 3 of the impeller structure above the lower baffle 4 through the liquid inlet pipe 6, and then is thrown outward by the rotating rotor 3 to be broken and separated, and flows down to the bottom of the cylinder 1 under the blocking effect of the inner wall of the cylinder 1. When the accumulated liquid in the cylinder 1 reaches a certain level, the discharge port 1.2 is opened to discharge the liquid.

[0020] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
