Description

Technical Field

[0001] This utility model relates to the technical field of defoamer processing equipment, specifically a cooling tank for processing high-efficiency defoamers. Background Technology

[0002] In the production of defoamers, the materials after high-temperature reaction need to undergo rapid and uniform cooling to ensure stable product performance. Traditional cooling tanks mostly adopt a jacketed heat exchange structure, where condensate is directly introduced into the jacket layer for heat exchange.

[0003] However, this type of structure has the following technical drawbacks:

[0004] 1. Low heat exchange efficiency: The traditional jacketed flow channel design is simple, the condensate flow path is short and the flow velocity distribution is uneven, resulting in insufficient heat exchange time, insufficient heat transfer, and the cooling rate is difficult to meet the needs of high-efficiency production.

[0005] 2. Significant temperature gradient: Due to the lack of an effective fluid disturbance mechanism, condensate is prone to form a laminar flow state in the jacket, which increases the boundary layer thermal resistance. Furthermore, the defoamer is prone to local temperature unevenness in the tank due to insufficient stirring, which affects product quality.

[0006] Therefore, we propose a cooling tank for processing high-efficiency defoamers. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a cooling tank for processing high-efficiency defoamers, which has the following beneficial effects:

[0018] 1. This high-efficiency defoamer processing cooling tank extends the flow path of condensate through a spiral guide plate, increases the heat exchange time, and allows the low-temperature condensate to fully contact the outer wall of the cooling tank, thereby improving the heat exchange efficiency. The turbulence protrusions disrupt the laminar boundary layer of the condensate, enhance the turbulence effect, reduce thermal resistance, and further improve the heat transfer performance, enabling the defoamer to cool down rapidly.

[0019] 2. This cooling tank for processing high-efficiency defoamer features a spiral guide plate with a variable pitch design. The pitch at the inlet is smaller to increase the flow rate of condensate and prevent water accumulation at the bottom; the pitch at the outlet is larger to reduce flow resistance, prevent excessive back pressure in the system, ensure stable operation of the external water pump, and reduce energy consumption.

[0020] 3. This cooling tank for processing high-efficiency defoamer has a stirring structure driven by a motor to rotate the stirrer, which ensures that the defoamer in the cooling tank is fully mixed, avoids local temperature differences, ensures uniform cooling, and improves product consistency.

[0021] 4. This cooling tank for processing high-efficiency defoamer has a sealed outer shell with a combination structure of inner stainless steel plate and outer polyurethane foam insulation layer, which effectively reduces the heat exchange between condensate and the outside, improves energy utilization, and prevents condensation on the outer shell.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] This embodiment is a cooling tank for processing high-efficiency defoamers.

[0029] like Figure 1-4 As shown, the device includes a cooling tank 1. A stirring structure 4 is installed at the upper end of the cooling tank 1. The stirring structure 4 includes a motor 12, a rotating shaft 13, and a stirrer 14. A discharge port 5 is installed in the middle of the lower outer surface of the cooling tank 1. A feed port 3 is installed on one side of the upper outer surface of the cooling tank 1. A bracket 6 is fixedly installed on the lower outer surface of the cooling tank 1. A sealing shell 2 is fixedly installed on the outer wall of the cooling tank 1. The sealing shell 2 is composed of a sandwich shell 15, an inner stainless steel plate 16, and an outer polyurethane foam insulation layer 17. A condensate inlet 7 and a drain valve 9 are installed at the lower part of one side of the outer surface of the sealing shell 2. A condensate outlet 8 is installed at the upper part of the other side of the outer surface of the sealing shell 2. A heat exchange cavity is provided between the outer wall of the cooling tank 1 and the inner wall of the sealing shell 2. A spiral guide plate 10 is installed in the heat exchange cavity. A turbulence protrusion 11 is fixedly installed between the outer wall of the cooling tank 1 and the inner wall of the sealing shell 2.

[0030] The spiral guide plate 10 is fixed inside the heat exchange cavity, causing the condensate to spiral upward along the outer wall of the defoamer tank; the turbulence protrusion 11 is fixed on the outer wall of the cooling tank 1 and the inner wall of the inner stainless steel plate 16, used to disrupt the condensate flow boundary layer; the pitch of the spiral guide plate 10 gradually increases from the condensate inlet 7 to the condensate outlet 8, forming a variable diameter spiral flow channel; the motor 12 is fixedly installed in the middle of the upper outer surface of the cooling tank 1, the stirrer 14 is located inside the cooling tank 1, and the rotating shaft 13 is connected to... At the lower outer surface of the motor 12, the stirrer 14 is fixedly installed on the outer wall of the rotating shaft 13. A coupling is provided between the rotating shaft 13 and the motor 12. The upper outer surface of the rotating shaft 13 is fixedly connected to the lower outer surface of the output shaft in the motor 12 through the coupling. A bearing is provided between the rotating shaft 13 and the cooling tank 1. The rotating shaft 13 is rotatably connected to the cooling tank 1 through the bearing. The outer polyurethane foam insulation layer 17 is filled between the inner wall of the sandwich shell 15 and the outer wall of the inner stainless steel plate 16.

[0031] It should be noted that this utility model is a cooling tank for processing high-efficiency defoamer. The defoamer is added into the interior of the cooling tank 1 through the feed port 3. Low-temperature condensate is sent into the interlayer between the outer wall of the cooling tank 1 and the inner wall of the sealed outer shell 2 through the condensate inlet 7, thereby cooling the defoamer inside the cooling tank 1. The spiral guide plate extends the flow path of the condensate, increasing the heat exchange time. The turbulence protrusions break the boundary layer of the condensate flow, enhance turbulence, and improve the heat transfer efficiency. The spiral guide plate gradually increases in diameter from the condensate inlet to the condensate outlet, forming a variable diameter spiral flow channel. The small pitch at the inlet is to increase the initial velocity of the water flow and avoid water accumulation at the bottom due to gravity. The large pitch at the outlet is to reduce flow resistance and prevent excessive back pressure in the system from affecting the operation of the external water pump. The stirring structure is set up so that the rotating shaft is driven by the operation of the motor, which drives the stirrer to rotate, thereby stirring the interior of the cooling tank and making the liquid cool more evenly.
