Description

Technical Field

[0001] The utility model relates to the field of water ring vacuum pumps, in particular to a circulating softening water device of a water ring vacuum pump. Background Art

[0002] The water ring vacuum pump mainly uses the rotating impeller to throw water or other liquids into the pump casing to form a closed liquid ring, thereby realizing the suction, compression and discharge of gas.

[0003] During the operation of a water ring vacuum pump, the quality of the circulating water has a significant impact on the performance and life of the equipment. Calcium and magnesium ions in hard water can form scale layers inside the pump. Therefore, existing water ring vacuum pumps usually require softening water when circulating water to remove calcium and magnesium ions and prevent scale formation.

[0004] However, continuous and repeated water softening not only increases operating costs, but in actual operation, existing water ring vacuum pumps often cannot choose whether to perform water softening according to the water quality. This leads to unnecessary water softening in some cases, even if the water quality is already soft enough, thus wasting resources and costs. Utility Model Content

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example

[0030] Reference Figures 1-4 , a water ring vacuum pump circulating softening water device, comprising: a cooling box 1; the cooling box 1, as a key component of the entire circulation system, not only provides the necessary cooling medium for the water ring vacuum pump 2, but also plays the role of storing and preliminarily treating the circulating water; the water ring vacuum pump 2, is connected to the cooling box 1; a detector 3, installed on one side of the cooling box 1, is used to detect the water quality. The detector 3 can monitor the water quality status of the circulating water in real time, including multiple indicators such as hardness, pH value, turbidity, etc., to provide accurate data support for subsequent treatment measures; a circulating pump 4, connected to the detector 3, is used as the power to drive the circulating water flow. source, ensuring that the circulating water can circulate continuously and stably throughout the system; the three-way valve 6, the water inlet is connected to the circulating pump 4, one of the water outlets is connected to the water ring vacuum pump 2, and the other water outlet is connected to the water softener 5, and the water softener 5 is connected to the water ring vacuum pump 2. According to the water quality data provided by the detector 3, the three-way valve 6 can automatically switch the water outlet to guide the circulating water to the water softener 5 or directly return it to the water ring vacuum pump 2, which not only ensures that the water quality meets the standards, but also avoids unnecessary soft water treatment costs. The water softener 5, as the key processing equipment of this device, effectively prevents the formation of scale by removing hardness ions in the circulating water.

[0031] The water ring vacuum pump 2 includes an air inlet end and an air outlet end, the air outlet end is connected to a return pipe 202, one end of the return pipe 202 is connected to the cooling box 1; the liquid inlet pipe 201 has one end installed in the liquid inlet end of the water ring vacuum pump 2, and the other end is connected to a three-way pipe 7.

[0032] The three-way valve 6 includes: a second delivery pipe 601, one end of which is installed on one of the water outlets of the three-way valve 6 and the other end is connected to the three-way pipe 7; a connecting pipe 602, one end of which is installed on the other water outlet of the three-way valve 6 and the other end is connected to the water softener 5.

[0033] The water softener 5 includes a first delivery pipe 501 , one end of which is connected to the water softener 5 , and the other end of which is connected to the tee pipe 7 . The first delivery pipe 501 and the second delivery pipe 601 are symmetrically arranged.

[0034] The three-way pipe 7 includes two one-way valves 701. The first delivery pipe 501 and the second delivery pipe 601 are respectively connected to the two one-way valves 701. The design of the three-way pipe 7 realizes the flexible switching of circulating water between the water softener 5 and the direct return water ring vacuum pump 2. The addition of the two one-way valves 701 prevents the water from flowing in the opposite direction, ensuring the stable operation of the system.

[0035] The three-way valve 6 adopts an electric three-way valve 6 , and the detector 3 adopts a multi-parameter water quality detector 3 . Example

[0036] The difference between this embodiment and the first embodiment is that the three-way valve 6 is a manual three-way ball valve.

[0037] During use, the circulation pump 4 is started and starts working, driving the circulating water in the cooling box 1 to flow. The circulating water enters the water ring vacuum pump 2 through the liquid inlet pipe 201, passes through the working area of ​​the water ring vacuum pump 2, and returns to the cooling box 1 through the return pipe 202 at the air outlet end, forming a preliminary cycle. During this process, the detector 3 monitors the water quality of the circulating water in real time. The detector 3 feeds back the real-time monitored water quality data to the control system. The control system analyzes the water quality data according to the preset water quality standard. If the water quality meets the standard (that is, the hardness, pH value, turbidity and other indicators are within the allowable range), the electric three-way valve 6 maintains the current state, and the circulating water continues to return directly to the water ring vacuum pump 2 without passing through the water softener 5 Treatment. If the water quality does not meet the standard, the control system will issue a command, and the electric three-way valve 6 will automatically switch the water outlet to guide the circulating water to the water softener 5. After the circulating water enters the water softener 5, the water softener 5 removes the hardness ions (such as calcium and magnesium ions) in the water to prevent the formation of scale. The treated softened water returns to the three-way pipe 7 through the first delivery pipe 501, and then passes through one water outlet of the three-way valve 6 (which has been switched to the water softener 5 side at this time), and finally returns to the water ring vacuum pump 2. In this process, the two one-way valves 701 ensure that the water flow can only flow in the predetermined direction, preventing the system instability caused by the reverse flow of water. The detector 3 continuously monitors the quality of the treated water to ensure that the water quality always remains within the allowable range.

[0038] In summary, compared with the existing technology, it has the following beneficial effects:

[0039] The detector 3 monitors the water quality of the circulating water in real time, providing accurate data support for subsequent treatment measures. Based on the real-time monitored water quality data, the electric three-way valve 6 can automatically switch the water outlet. When the water quality meets the standards, the circulating water directly returns to the water ring vacuum pump 2 without being processed by the water softener 5, reducing the consumption of water softener and water resources.

[0040] By optimizing the operating logic of the circulating water system, the effective utilization and recycling of circulating water is achieved, the resource utilization efficiency is improved, and the reliability and stability of the equipment are enhanced.
