Description

Technical Field

[0001] This utility model relates to the field of chemical cleaning agent dissolution technology, specifically a chemical cleaning agent dissolution tank based on secondary steam recycling. Background Technology

[0002] A chemical cleaning agent dissolving tank is a device used to store and dissolve chemical cleaning agents. It is commonly used in industrial, manufacturing, or repair fields. Its main function is to dissolve solid or concentrated chemical cleaning agents into liquids to facilitate subsequent cleaning or treatment processes.

[0003] In existing technologies, traditional chemical cleaning agent dissolving tanks rely on electrically driven stirrers and independent electric heating devices, which result in high energy consumption and high operating costs.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN211988244U) discloses a stirring and dissolving device for producing reverse osmosis cleaning agents with anti-splash effect. The device includes a base, a stirring tank located at the upper middle of the base, a horizontal plate above the stirring tank, a first support plate and a second support plate fixedly connected to the top two sides of the base respectively, and grooves on opposite sides of the first and second support plates. A motor is located at the top of the horizontal plate, and a cover plate is located at the bottom of the horizontal plate. A rotating rod is fixedly connected to the output end of the motor, and the end of the rotating rod away from the motor passes through the horizontal plate and the cover plate sequentially and extends downwards. Multiple sets of stirring rods are fixedly connected to the outer wall of the extended end of the rotating rod. A second motor is located at the top of the first support plate. This fixing mechanism improves the stability of the stirring tank, preventing shaking during stirring, and completely seals the stirring tank during stirring, preventing raw material splashing and waste.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, the secondary steam generated by flash tanks in industrial production is often directly discharged as a waste heat source, resulting in energy waste. Existing dissolving tanks lack effective design for utilizing secondary energy, which increases production costs and does not conform to the trend of green and energy-saving industrial development. Utility Model Content

[0009] Furthermore, a pneumatic regulating valve is provided at the upper end of the steam conveying pipe, and a pressure sensor is provided on the surface of the steam conveying pipe, and a temperature sensor is installed at the right end of the tank.

[0010] Furthermore, the lower end of the steam conveying pipe is connected to an annular injection pipe, which is arranged in two layers, with three injection pipes in each layer.

The injection holes of adjacent layers of annular injection pipes are staggered at 45°. The injection angle of the upper annular injection pipe is 30° with the horizontal plane, and the lower annular injection pipe is at 45°, forming a three-dimensional spiral steam impact flow.

[0011] Furthermore, the inner wall of the tank is provided with a flow guiding groove, which is distributed in an Archimedean spiral pattern and is aligned with the steam injection direction.

[0012] Furthermore, the inner wall of the feed inlet is provided with two guide plates, and the left and right guide plates are staggered vertically, and the guide plates are inclined.

[0013] Furthermore, the insulation component is provided with an insulation layer, and the insulation layer is wrapped around the outside of the tank.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figures 1-4The technical solution shown is a chemical cleaning agent dissolving tank based on secondary steam recycling. To address the problem of energy waste, it discloses: a tank body 1 with an inlet 2 at the upper end and a pump outlet 3 at the lower end; a flash tank 4 at the right end of the tank body 1; a secondary steam recycling mechanism between the flash tank 4 and the tank body 1; a steam delivery pipe 6 connected at the lower end of the steam delivery pipe 6 to the interior of the tank body 1; and an upper end of the steam delivery pipe 6 connected to the outlet of the flash tank 4 via a connecting pipe 5. The upper end of the tank body 1 and the bottom of the flash tank 4 are connected via a condensate recovery pipe 8. A pneumatic regulating valve 9 is installed at the upper end of the steam delivery pipe 6, and a pressure sensor is installed on the surface of the steam delivery pipe 6. 10. A temperature sensor 11 is installed at the right end of the tank body 1. The lower end of the steam conveying pipe 6 is connected to an annular injection pipe 7. The annular injection pipe 7 is arranged in two layers, with three in each layer. The surface of each layer of the annular injection pipe 7 is evenly distributed with downward-sloping injection holes. The injection holes of adjacent layers of the annular injection pipe 7 are staggered at 45°. The injection angle of the upper annular injection pipe 7 is 30° with the horizontal plane, and the lower annular injection pipe 7 is 45° with the horizontal plane, forming a three-dimensional spiral steam impact flow. The annular injection pipe 7 adopts a variable diameter design, with a larger diameter near the end of the steam conveying pipe 6 and gradually narrowing towards the end. The inner wall of the tank body 1 is provided with a flow guiding groove 12, which is distributed in an Archimedean spiral pattern and is matched with the steam injection direction.

[0027] When chemical cleaning agent is added into tank 1 through inlet 2, the flash tank 4 is activated, allowing heated steam to pass through connecting pipe 5 and be transported into the steam delivery pipe. Steam is then ejected through annular jet pipe 7 at the end of the steam delivery pipe. This impact-driven steam heats and sprays the chemical cleaning solution, generating a vortex that rotates and stirs the solution. This improves the dissolution rate and uniformity of the chemical cleaning agent, and ensures more even heating, solving the problems of low dissolution efficiency and uneven dissolution in existing dissolution tanks. Simultaneously, it makes heating more uniform and efficient, improving the cleaning efficiency of the chemical cleaning agent. Furthermore, as... Figure 3As shown, each layer of annular jet pipe 7 has downwardly sloping jet holes evenly distributed on its surface. The jet holes of adjacent layers are staggered at 45°. The upper layer of annular jet pipe 7 has a jet angle of 30° with the horizontal plane, while the lower layer has a 45° angle, forming a three-dimensional spiral steam impact flow. The annular jet pipe 7 adopts a variable diameter design, with a larger diameter at the end near the steam delivery pipe 6 and gradually narrowing at the end to maintain uniform steam jet pressure. The inner wall of the tank 1 is provided with flow guide grooves 12, which are distributed in an Archimedean spiral pattern and are matched with the steam jet direction to enhance the vortex effect. The pneumatic regulating valve 9 is used to regulate the pressure of the secondary steam. At the same time, it works with the pressure sensor 10 and the temperature sensor 11 to accurately sense the pressure and temperature inside the tank 1. The condensate recovery pipe 8 is also provided to recover the condensate, which is then discharged into the tank 1 through the pump outlet 3 after the chemical cleaning agent treatment is completed.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of easy heat loss: an insulation component is provided on the outer side of the tank 1, two guide plates 13 are provided on the inner wall of the feed inlet 2, and the left and right guide plates 13 are staggered vertically and inclined, and the insulation component is provided with an insulation layer 14, which wraps around the outer side of the tank 1.

[0029] An insulation layer 14 is wrapped around the outside of the tank body 1. The adhesion of the insulation layer 14 can reduce heat loss and improve the insulation effect of the tank body 1, which can further improve the thermal energy utilization rate of steam. At the same time, two inclined guide plates 13 are provided on the inside of the feed inlet 2, which can play a guiding role when adding chemical cleaning agents and avoid splashing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
