Description

Technical Field

[0001] This utility model relates to the field of vacuum degassing machine technology, specifically a circulating water vacuum degassing machine. Background Technology

[0002] A circulating water vacuum deaerator is a device used to remove dissolved gases from water, and is commonly used in industrial cooling systems, heating, ventilation, and air conditioning (HVAC) systems, and boiler feedwater treatment. This device works by reducing the pressure below the solubility of gases in water, causing the gases to precipitate and thus purifying the water.

[0003] In the operation of a circulating water vacuum degasser, heating is typically used to effectively accelerate gas movement, thereby facilitating degassing. For example, Chinese Patent (CN218794035U) discloses a circulating water vacuum degasser, including a base, a degassing tank fixedly installed on one side of the upper end of the base, a degassing pump fixedly installed on the upper end of the base and on one side of the degassing tank, and a control box located on the other side of the upper end of the base. Several heating rods are embedded inside the upper edge of the degassing tank to enable rapid degassing of gas from the water inside the degassing tank, thus facilitating the operation of the vacuum degasser. To increase efficiency, several heating rods are embedded inside the upper edge of the degassing tank. These heating rods heat the inner wall of the degassing tank, thereby increasing the ambient temperature inside and accelerating the rate of gas removal from the water. As can be seen from the above, adding heating rods does indeed increase the gas removal rate. However, in such a circulating water treatment process, if there are a large number of impurities in the circulating water, these impurities can easily affect the normal operation of the entire device and reduce its efficiency. Therefore, we propose a circulating water vacuum degassing machine. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a circulating water vacuum degasser, including a mounting plate 1. A control box 6 is fixedly mounted on the top of the mounting plate 1 by two sets of support frames 5. A degassing mechanism 2 is fixedly mounted on the top of the mounting plate 1. A degassing pump 3 is fixedly mounted on the top of the mounting plate 1 and on one side of the degassing mechanism 2. The degassing mechanism 2 and the degassing pump 3 are fixedly connected by a connecting pipe 4. A filter mechanism 7 for removing large impurities from the circulating water is fixedly connected to one side of the degassing mechanism 2.

[0018] The degassing mechanism 2 can increase the treatment temperature of the circulating water. This configuration can accelerate the removal rate of gas from the water in the degassing mechanism 2 by utilizing the higher internal ambient temperature of the degassing mechanism 2. The degassing pump 3 can create a low-pressure or even vacuum environment, which facilitates the rapid removal of gas from the circulating water by the degassing mechanism 2. Before degassing, the circulating water to be treated can be preliminarily filtered by the filtration mechanism 7, thereby preventing impurities in the circulating water from entering the entire device and affecting its normal operation.

[0019] Please see Figure 1 The degassing mechanism 2 includes support legs 8, a degassing tank 9, and heating rods 10. The degassing tank 9 is fixedly installed on the top of the mounting plate 1 by multiple sets of support legs 8, and multiple sets of heating rods 10 are arranged through the degassing tank 9.

[0020] The degassing tank 9 has multiple sets of heating rods 10 running through its interior. The heating rods 10 can increase the temperature of the inner wall of the degassing tank 9. This setting can increase the processing temperature when circulating water enters, and can accelerate the rate of gas removal from the water in the degassing mechanism.

[0021] Please see Figure 1 outdoor Figure 2The filtration mechanism 7 includes a filter tank 11, a sealing cover 12, locking bolts 13, a filter screen 14, an inlet pipe 17, and an outlet pipe 18. The inlet pipe 17 and the outlet pipe 18 are fixedly connected to both sides of the filter tank 11, respectively. One side of the outlet pipe 18 is connected to the degassing tank 9. The sealing cover 12 is fixedly installed on the top of the filter tank 11 by multiple sets of locking bolts 13. The filter screen 14 is fixedly installed inside the filter tank 11. The top of the filter screen 14 is inclined. A sealing plate 15 that fits against the inner wall of the filter tank 11 is fixedly connected to the top of the filter screen 14.

[0022] The circulating water to be treated enters the interior of the filter tank 11 through the inlet pipe 17. Then, the circulating water passes through the filter tank 11 and the sealing plate 15 on one side of the lower sealing plate to filter impurities. The treated circulating water can then be discharged into the dehydration tank 9 through the outlet pipe 18. The top of the outlet pipe 18 is lower than the bottom of the outlet pipe 18, which prevents untreated impurities from entering the dehydration tank 9 through the outlet pipe 18.

[0023] Please see Figure 1 , Figure 2 and Figure 3 A fixing plate 19 is fixedly connected to the bottom of the inner wall of the filter tank 11, and a locking plate 20 is fixedly connected to the top of the fixing plate 19. A fixing groove 21 is provided on the locking plate 20, and a fixing block 22 inserted into the fixing groove 21 is fixedly connected to the bottom of the filter screen 14.

[0024] When placing the filter screen 14, the fixing block 22 at the bottom of the filter screen 14 is inserted into the fixing groove 21 on the locking plate 20. This setting can prevent the filter screen 14 from rotating when the circulating water enters and generates pressure, thus affecting the filtration efficiency.

[0025] Please see Figure 1 , Figure 2 and Figure 3 A pull ring 16 is fixedly connected to the top of the sealing plate 15, and a sealing gasket that fits against the inner wall of the filter tank 11 is fixedly connected to the outer wall of the sealing plate 15. A sealing gasket that fits against the top of the filter tank 11 is fixedly connected to the bottom of the sealing cover 12. The sealing gasket is made of rubber.

[0026] When too many impurities accumulate inside the filter screen 14, opening the sealing cover 12 and pulling the pull ring 16 will allow the filter screen 14 to be removed from the filter tank 11, making it convenient to clean the impurities in the filter screen 14.

[0027] In operation, the degassing mechanism 2 increases the processing temperature of the circulating water. This design utilizes the higher internal temperature of the degassing mechanism 2 to accelerate the removal rate of gas from the water. The degassing pump 3 creates a low-pressure or even vacuum environment, facilitating the rapid removal of gas from the circulating water using the degassing mechanism 2. Before degassing, the circulating water to be treated is preliminarily filtered by the filtration mechanism 7 to prevent impurities from entering the entire device and affecting its normal operation. Multiple heating rods 10 are installed throughout the degassing tank 9. These heating rods 10 increase the internal wall temperature of the degassing tank 9, thus increasing the processing temperature when the circulating water enters. The gas removal rate in the water within the rapid degassing mechanism is such that the circulating water to be treated enters the filter tank 11 through the inlet pipe 17. Subsequently, the circulating water passes through the filter tank 11 and the sealing plate 15 on one side of the lower-height sealing plate 15 for impurity filtration. The treated circulating water then flows through the outlet pipe 18 into the dehydration tank 9. The top of the outlet pipe 18 is lower than the bottom of the outlet pipe 18, which prevents untreated impurities from entering the dehydration tank 9 through the outlet pipe 18. When the filter screen 14 is placed, the fixing block 22 at the bottom of the filter screen 14 is inserted into the fixing groove 21 on the locking plate 20. This arrangement prevents the filter screen 14 from rotating when the circulating water enters and generates pressure, thus affecting the filtration efficiency.

[0028] 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.
