Description

Technical Field

[0001] The invention relates to the field of cooling equipment, in particular to a cooling water circulation system. Background Art

[0002] Thermal power generation generally uses the heat energy generated by the combustion of combustibles to heat water, turning the water into high-temperature, high-pressure steam, and then the steam drives the generator to generate electricity. The main equipment systems of thermal power generation include: fuel supply system, water supply system, steam system, cooling system, electrical system and some other auxiliary processing equipment. In the cooling system, water resources are cooled and recycled, and in the long-term use of circulating cooling water, it is necessary to regularly add water quality stabilizing agents, bactericides, etc., in order to effectively control the scaling of the circulating cooling water system, control the corrosion of equipment and piping, and inhibit the growth of microorganisms in the water.

[0003] The current method of adding chemicals to cooling water is basically to add chemicals directly to the cooling water through the pipe dosing port. However, this method easily leads to a large amount of chemicals being added to the cooling water in the same area, resulting in different amounts of cooling water chemicals added in different areas. It is also easy for cooling water in areas with less added amounts to form scale and breed microorganisms. If the cooling water in different areas is supplemented with chemicals separately for multiple times, it will be difficult to determine the dividing criteria between areas, and the flow rate of the cooling water will also affect the location where the chemicals are added. Summary of the invention

[0004] The object of the present invention is to provide a cooling water circulation system which improves the convenience of cooling water agent replenishment and can premix agents to prevent a large amount of agents from being added to the cooling water in the same area, resulting in different amounts of cooling water agent replenishment in different areas.

[0006] A premixing ring is rotatably arranged on the inner circle of the dosing ring, a plurality of premixing rods are circumferentially spaced apart on one side of the premixing ring close to the premixing chamber, a plurality of water guide plates are circumferentially spaced apart on one side of the premixing ring away from the premixing chamber, and the water guide plates are inclined along the water inlet direction.

[0007] Furthermore, an inlet sleeve is extended and arranged at the side of the water inlet, and an outlet sleeve is extended and arranged at the side of the water outlet. Both ends of the adjusting rod are movably arranged in the inlet sleeve and the outlet sleeve respectively.

The inlet groove and the outlet groove are communicated through a waterway, and a plurality of through grooves communicated with the premixing chamber are circumferentially formed at the middle position of the waterway.

[0008] Furthermore, a first elastic member is connected between the inner side of the inlet sleeve and the end of the adjusting rod, and a second elastic member is connected between the inner side of the outlet sleeve and the end of the adjusting rod, so that when pressing one end of the adjusting rod located in the inlet sleeve, the outlet groove is communicated to the medicine delivery tube, and when pressing one end of the adjusting rod located in the outlet sleeve, the inlet groove is communicated to the medicine delivery tube.

[0009] Furthermore, an auxiliary ring is movably arranged inside the medicine delivery tube. The auxiliary ring and the medicine delivery ring are symmetrically arranged, and the moving directions of the auxiliary ring and the medicine delivery ring are opposite. A plurality of top blocks are circumferentially arranged at intervals on one side of the auxiliary ring close to the medicine delivery ring. The top blocks are matched with the end of the adjusting rod with the outlet groove.

[0010] Furthermore, a limiting groove is formed at the end of the medicine delivery tube, and the ejector rod is detachably installed in the limiting groove and is matched with the end of the adjusting rod with the inlet groove.

[0011] Furthermore, a rubber sleeve is sleeved at one end of the limiting groove inside the medicine delivery tube, and the end of the ejector rod abuts against the inner side of the rubber sleeve.

[0012] Furthermore, an air inlet communicated with the premixing chamber is formed at the side of the medicine delivery ring, and an air groove is formed at the side of the medicine delivery tube. An air pipe is connected between the air inlet and the air groove, so that the air groove supplies air to the premixing chamber through the air pipe and the air inlet.

Therefore, the above terms should not be construed as limiting the present invention.

[0025] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, and in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0026] As Figures 1-6 described, the present invention provides a cooling water circulation system, including a water inlet pipe 1, a water outlet pipe 2, and a medicine delivery pipe 3 for connecting the water inlet pipe 1 and the water outlet pipe 2. A medicine delivery ring 4 is movably arranged inside the medicine delivery pipe 3. A premixing chamber 5 is circumferentially opened inside the medicine delivery ring 4. An inlet 6 and an outlet 7 are respectively opened on both sides of the premixing chamber 5, so that water enters at the inlet 6 to premix the medicine in the premixing chamber 5, and the premixed liquid medicine is discharged into the medicine delivery pipe 3 at the outlet 7; a medicine delivery port 8 communicating with the premixing chamber 5 is opened on the side of the medicine delivery ring 4, and a medicine adding port 9 matching the medicine delivery port 8 is opened on the side of the medicine delivery pipe 3, so that when the medicine delivery port 8 is communicated with the medicine adding port 9, the medicine enters the premixing chamber 5 through the medicine adding port 9 and the medicine delivery port 8.

[0027] By moving the medicine delivery ring to the position of the medicine adding port, the medicine adding port is made to match the medicine delivery port. At this time, the premixing chamber is replenished with medicine through the medicine adding port. After the replenishment is completed, the medicine adding port is closed, and the cooling water in the medicine delivery pipe is guided into the premixing chamber through the inlet, so that a small part of the cooling water is premixed with the cooling water in the premixing chamber. After premixing to a certain extent, the outlet is opened, and the premixed medicine together with the cooling water is discharged into the medicine delivery pipe at a certain discharge speed. Since the medicine has been premixed at this time, it is more easily incorporated into the cooling water in the medicine delivery pipe, and the discharge method at a certain speed can ensure that the cooling water in each position area has the same supplementary medicine dosage during the discharge process.

[0028] Among them, the water inlet pipe and the water outlet pipe are connected to the cooling water circulation system, and the drug delivery tube can be installed in multiple areas of the cooling water circulation system; the drug is a water quality stabilizer, a bactericide, etc.

[0029] Preferably, a premixing ring 10 is rotatably arranged on the inner circle of the dosing ring 4, and a plurality of premixing rods 11 are circumferentially spaced apart on the side of the premixing ring 10 close to the premixing chamber 5, and a plurality of water guide plates 12 are circumferentially spaced apart on the side of the premixing ring 10 away from the premixing chamber 5, and the water guide plates 12 are inclined along the water inlet direction.

[0030] Specifically, after the medicine enters the premixing chamber and the cooling water in the dosing tube enters the premixing chamber from the water inlet, the water inlet pipe continues to supply water to the dosing tube. When the cooling water in the dosing tube passes through the inner circle of the dosing ring, the circulating cooling water will contact the water guide plate and be guided by the inclined direction of the water guide plate. At this time, the water guide plate will drive the premixing ring to rotate under the impact of the water flow, thereby allowing the several premixing rods in the premixing chamber to premix and stir the medicine and cooling water in the premixing chamber, thereby improving the effect of premixing of the medicine in the premixing chamber. This does not require additional power drive and can be accomplished only by the self-flow of cooling water.

[0031] Preferably, a water inlet sleeve 13 is extended on the side of the water inlet 6, and a water outlet sleeve 14 is extended on the side of the water outlet 7. Both ends of the adjusting rod 15 are movably arranged in the water inlet sleeve 13 and the water outlet sleeve 14 respectively, and a water inlet groove 16 is provided at the end of the adjusting rod 15 close to the water inlet sleeve 13, and a water outlet groove 17 is provided at the end of the adjusting rod 15 close to the water outlet sleeve 14. The water inlet groove 16 and the water outlet groove 17 are connected through a water channel 18, and a plurality of through grooves 19 connected to the premixing chamber 5 are circumferentially provided in the middle of the water channel 18.

[0032] Specifically, when it is necessary to replenish water in the premixing chamber, the push-up adjusting rod has one end of the water outlet groove, so that the adjusting rod is moved toward one end of the water inlet groove, and the water inlet groove is moved to the outside of the water inlet sleeve, so that the cooling water in the dosing tube can be connected to the adjusting rod along the water path through the water inlet groove, and the cooling water is discharged to the premixing chamber through each through groove to ensure sufficient premixing of the medicine and the cooling water. After the premixing is completed, the adjusting rod is pushed in the opposite direction to move the adjusting rod to one end of the water outlet groove, so that the water outlet groove is moved to the outside of the water outlet sleeve, and the premixed medicine is discharged to the dosing tube along the through groove, the water path, and the water outlet groove in conjunction with the injection of compressed air into the premixing chamber, so as to achieve the purpose of fully and evenly discharging the medicine into the cooling water circulation system.

[0033] Preferably, a first elastic member 20 is connected between the inner side of the water inlet sleeve 13 and the end of the adjusting rod 15, and a second elastic member 21 is connected between the inner side of the water outlet sleeve 14 and the end of the adjusting rod 15, so that when pressing one end of the adjusting rod 15 located in the water inlet sleeve 13, the water outlet groove 17 communicates with the medicine delivery tube 3, and when pressing one end of the adjusting rod 15 located in the water outlet sleeve 14, the water inlet groove 16 communicates with the medicine delivery tube 3.

[0034] Specifically, after pressing the end of the adjusting rod, the first elastic member and the second elastic member assist in pushing the adjusting rod to reset subsequently, so that both ends of the adjusting rod are held at the position between the water outlet sleeve and the water inlet sleeve under the propping of the first elastic member and the second elastic member, thereby ensuring the closure of the water inlet groove and the water outlet groove under normal conditions.

[0035] In an embodiment of this solution, the first elastic member and the second elastic member can adopt a spring structure.

[0036] Preferably, an auxiliary ring 22 is movably arranged inside the medicine delivery tube 3. The auxiliary ring 22 and the medicine delivery ring 4 are symmetrically arranged, and the moving directions of the auxiliary ring 22 and the medicine delivery ring 4 are opposite. A plurality of top blocks 23 are circumferentially spaced on the side of the auxiliary ring 22 close to the medicine delivery ring 4, and the top blocks 23 match the end of the adjusting rod 15 with the water outlet groove 17.

[0037] Specifically, when water needs to be supplied to the premixing chamber, the medicine delivery ring and the auxiliary ring move closer to each other, so that the top blocks contact the end of the adjusting rod, and the adjusting rod is pushed towards the end of the water inlet groove by the top blocks to ensure the stable water supply of the premixing chamber. At the same time, during the relative movement or the opposite movement of the medicine delivery ring and the auxiliary ring, the inner wall of the medicine delivery tube can also be scaled by the two ring structures to prevent the situation that the medicine cannot smoothly enter the cooling water circulation system due to the scaling of the inner wall of the medicine delivery tube.

[0038] Preferably, a limiting groove 24 is opened at the end of the medicine delivery tube 3, and the ejector rod 25 is detachably installed in the limiting groove 24, and the ejector rod 25 matches the end of the adjusting rod 15 with the water inlet groove 16.

[0039] Specifically, through the arrangement of the ejector rod, when the medicine delivery ring moves to the position of the ejector rod, the ejector rod pushes the end of the adjusting rod, so that the end of the adjusting rod with the water outlet groove moves outwards to ensure the stable discharge of the premixed medicine.

[0040] Preferably, a rubber sleeve 26 is sleeved at the end of the limiting groove 24 inside the medicine delivery tube 3, and the end of the ejector rod 25 props against the inner side of the rubber sleeve 26.

[0041] Specifically, the opening position of the limit groove is sealed by a rubber sleeve to prevent water leakage when the ejector rod is replaced. Moreover, due to the rubber sleeve being subjected to the propping action of the ejector rod, when replacing ejector rods of different length specifications, the ejection depth of the adjusting rod can be adjusted, and thus the exposed length of the water outlet groove can be adjusted, so as to conveniently control the discharge speed, discharge volume, etc. of the premixed medicament, enabling the user to select the discharge of the premixed medicament according to the current flow rate of the cooling water circulation system to adapt to the current flow rate.

[0042] In an embodiment of this solution, the ejector rod and the limit groove are in a threaded fit, enabling the position of the end of the ejector rod to be adjusted by rotation, and thus adjusting the propping depth of the adjusting rod.

[0043] Preferably, an air inlet 27 communicating with the premixing chamber 5 is provided on the side of the dosing ring 4, an air groove 28 is provided on the side of the dosing tube 3, and an air tube 29 is connected between the air inlet 27 and the air groove 28, so that the air groove 28 supplies air to the premixing chamber 5 via the air tube 29 and the air inlet 27.

[0044] Specifically, when the premixed medicament needs to be discharged into the dosing tube, the air groove supplies compressed air to the premixing chamber through the air tube and the air inlet, and then discharges the premixed medicament into the dosing tube through the compressed air to ensure the stable discharge of the premixed medicament.

[0045] In an embodiment of this solution, the dosing tube is usually placed in a vertical state, and one end of the adjusting rod with a water outlet groove is oriented downward to facilitate the discharge of the premixed medicament.

[0046] It is worth mentioning that the air tube adopts a corrugated tube or a hose structure to ensure that the air tube can move with the dosing ring; a valve is provided at the air inlet to ensure that the medicament does not leak out from the air tube; the outside of the air groove is communicated with an external air supply device.

[0047] Preferably, a moving groove 30 is provided on the inner side of the dosing tube 3, both the dosing ring 4 and the auxiliary ring 22 have sliders 31 on their sides, the sliders 31 are in a moving fit with the moving groove 30, and a lead screw 32 is rotatably arranged in the moving groove 30. The lead screw 32 passes through the slider 31 and is in a threaded fit with the slider 31.

[0048] Specifically, through the cooperation of the slider and the moving groove, the path of the dosing ring and the auxiliary ring moving along the inner wall of the dosing tube is made more accurate. At the same time, the stability during the movement of the two is improved by the lead screw, and the effect during the scraping movement of the two against the inner wall of the dosing tube is increased.

[0049] Among them, the lead screw can be rotated by being controlled by a motor.

[0050] Preferably, a plug 33 is provided at the chemical addition port 9 so that when the chemical addition port is not in use, the chemical addition port can be blocked by the plug to prevent the cooling water from leaking out from the chemical addition port.

[0051] The present invention is not limited to the above-mentioned optimal implementation manner. Any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as the present application, it falls within the protection scope of the present invention.
