Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a circulating water treatment device. Background Art

[0002] Circulating water is often required in the production of stainless steel pipes. For example, in the manufacturing process of stainless steel pipes, processes such as cold drawing and cold rolling will generate a lot of heat, which requires circulating water for cooling to prevent the material from overheating, deformation or damage. Circulating water is also used to clean the inner and outer walls of stainless steel pipes, removing impurities such as oil and rust to ensure the cleanliness of the pipe surface. After long-term use of circulating water, impurities will inevitably be generated in the water, so it needs to be treated.

[0003] The circulating water treatment device in the prior art often requires the use of an adjustment auxiliary agent during use. However, the supply amount of the auxiliary agent cannot be adjusted at any time during actual use, which may cause unnecessary waste. At the same time, the reaction between the auxiliary agent and the circulating water to be treated may not be sufficient, thereby reducing the use efficiency of the auxiliary agent. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a circulating water quality treatment device, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a circulating water quality treatment device, comprising a water tank, a water inlet pipe is fixedly installed at the rear of the water tank, a transmission device is provided at the rear of the water tank, the transmission device comprises a motor, a flow sensor, a vane wheel, an L-shaped mandrel and a protrusion, the motor is fixedly mounted on the circumferential surface of the water inlet pipe, the flow sensor is fixedly mounted on the top of the circumferential surface of the water inlet pipe, the vane wheel is fixedly mounted on the output end of the motor, the L-shaped mandrel is slidably mounted on the top of the water tank, the protrusion is fixedly mounted on the top of the L-shaped mandrel, a medicine cartridge is fixedly mounted on the top of the water tank, a medicine feeding device is provided on the top of the water tank, a U-shaped mandrel is slidably mounted on the circumferential surface of the medicine cartridge, a filter is fixedly mounted on the inner wall of the medicine cartridge, The inner wall of the cartridge is fixedly installed with an inner top cover, the top of the inner top cover is rotatably penetrated by a spiral groove rod, the bottom of the U-shaped top rod is rotatably installed with a clamping rod, the inside of the opening of the U-shaped top rod is rotatably installed with a tightening rod, the bottom of the inner top cover is slidably installed with a telescopic rod, and the bottom of the cartridge is rotatably installed with a spoon-shaped paddle. When the flow rate of the water inlet increases, the flow sensor sends a signal to increase the speed of the motor so that the rotary vane wheel provides more pressure to the L-shaped top rod under the action of centrifugal force, thereby increasing its displacement. The increase in displacement also increases the deflection angle of the spoon-shaped paddle, thereby increasing the supply amount of medicine when the water inlet flow rate increases, and reducing the supply amount of medicine when the water inlet flow rate decreases, thereby improving the use efficiency of the medicine and avoiding unnecessary waste in the medicine supply process.

[0006] The gear is rotated and mounted on the top of the water tank, and the conical rotor is rotatably mounted on the top of the inner wall of the water tank, the slotted rod is fixedly mounted on the bottom of the inner wall of the water tank, and the spiral is rotatably mounted on the top of the inner wall of the water tank, and the pressing plate is sleeved on the circumferential surface of the slotted rod, and the circumferential surface of the slotted rod is provided with a limiting groove, the upper part of the limiting groove is spiral, and the lower part of the limiting groove is linear. The movement of the L-shaped top rod drives the conical rotor and the spiral to rotate through the gear and the transmission belt, and the spiral drives it to move downward by contacting the pressing plate, thereby solving the problem that the medicine floats on the water surface and cannot fully react after supplying and the problem of uneven medicine supply. The medicine floating on the water surface is pressed into the water by the pressing plate, thereby accelerating the reaction speed.

[0007] According to the above technical solution, a medicine dispensing port is opened on the top of the water tank, and the front part of the L-shaped top rod contacts the side of the spoon-shaped paddle. This contact enables the back-and-forth reciprocating motion of the L-shaped top rod to drive the spoon-shaped paddle to deflect.

[0008] According to the above technical solution, a crushing rod is fixedly installed at the bottom of the spiral groove rod, and a transmission rod is fixedly installed on the side of the U-shaped top rod. The circumferential surface of the transmission rod at one end away from the U-shaped top rod contacts the inner wall of the spiral groove of the spiral groove rod. The up and down reciprocating motion of the U-shaped top rod drives the spiral groove rod to rotate through the transmission rod, thereby driving the crushing rod to rotate to crush the block medicine that cannot pass through the filter.

[0009] According to the above technical solution, the tightening rod is rotatably installed at the top of the fixed end of the telescopic rod at one end away from the U-shaped top rod, and the bottom of the telescopic rod is rotatably installed at the front of the clamping rod. The connection between the tightening rod and the telescopic rod enables the U-shaped top rod to reciprocate while driving the telescopic rod to reciprocate left and right, so as to realize the opening and closing movement of the clamping rod, thereby realizing the dredging of the medicine delivery port.

[0010] According to the above technical solution, a rack is provided on the front side of the L-shaped top rod, and the rack is meshed with a gear. A transmission rod is fixedly connected to the bottom of the gear, and the gear is fixedly connected to a pulley through the transmission rod. The transmission pulley and the conical rotor are connected by a transmission belt, and the transmission pulley and the spiral are connected by a transmission belt. The conical rotor is arranged below the medicine discharge port, and the rack on the side of the L-shaped top rod drives the conical rotor and the spiral blade to rotate through the gear meshed with it. The conical rotor can contact with the medicine released from the medicine discharge port and evenly spread the medicine to the center position inside the water tank, so that the medicine can react more fully with the circulating water.

[0011] According to the above technical solution, a large filter plate is fixedly installed inside the water tank, a water outlet pipe is provided at the front of the water tank, and a rotating shaft is provided on the branch of the vane wheel. The large filter plate can achieve a rough pre-treatment of the circulating water entering the water tank, so as to improve the efficiency of subsequent processing work and improve the overall water quality treatment quality.

[0012] According to the above technical solution, a spiral spring is arranged between the spoon-shaped paddle and the top of the water tank, and a return spring is arranged between the L-shaped top rod and the top of the water tank. The spiral spring and the return spring can reset the spoon-shaped paddle and the L-shaped top rod when the water flow decreases to reduce the supply amount of the medicine.

[0013] The present invention provides a circulating water quality treatment device. It has the following beneficial effects: (1) In this invention, when the flow rate at the water inlet increases, the flow sensor sends a signal to increase the speed of the motor, so that the vane wheel provides more pressure to the L-shaped push rod under the action of centrifugal force, thereby increasing its displacement. This increase in displacement also increases the deflection angle of the spoon-shaped paddle, thereby increasing the supply of medicine when the flow rate at the water inlet increases, and reducing the supply of medicine when the flow rate at the water inlet decreases, thereby improving the use efficiency of medicine and avoiding unnecessary waste in the medicine supply process.

[0014] (2) In this invention, the C-shaped top rod drives the spiral groove rod to rotate when it moves up and down. The spiral groove rod drives the crushing rod at its bottom to rotate to break up the agglomerated medicine that cannot pass through the filter screen. This avoids blockage in front of the medicine outlet when using block medicine, resulting in the medicine not being able to be supplied in time or the medicine agglomerating and being unusable, further improving the efficiency of the medicine use and optimizing the overall user experience of the device.

[0015] (3) In this invention, the movement of the L-shaped top rod drives the conical rotor and the spiral blade to rotate through the gears and the transmission belt. The spiral blade drives it to move downward by contacting the pressing plate, which solves the problem that the medicine floats on the water surface after feeding and cannot fully react, and the problem of uneven medicine feeding. The medicine floating on the water surface is pressed into the water by the pressing plate, thereby accelerating the reaction speed, improving the overall use efficiency of the device and improving the quality of the water after treatment.

The top of the U-shaped top rod 501 is rotatably mounted with a clamping rod 506, and the inside of the opening of the U-shaped top rod 501 is rotatably mounted with a tightening rod 507. The bottom of the inner top cover 504 is slidably mounted with a telescopic rod 505, and the bottom of the cartridge 4 is rotatably mounted with a spoon-shaped paddle 508. When the flow rate at the water inlet increases, the flow sensor 302 sends a signal to increase the speed of the motor 301, so that the vane wheel 303 provides more pressure to the L-shaped top rod 304 under the action of centrifugal force, thereby increasing its displacement. The increase in displacement also increases the deflection angle of the spoon-shaped paddle 508, thereby increasing the supply of medicine when the flow rate at the water inlet increases, and reducing the supply of medicine when the flow rate at the water inlet decreases, thereby improving the efficiency of the use of medicine and avoiding unnecessary waste in the medicine supply process.

[0020] The water tank 1 is provided with a medicine-uniforming device, which includes a gear 701, a conical vane 702, a slotted vertical rod 703, a spiral piece 704, a pressing plate 705 and a limiting groove 706. The gear 701 is rotatably mounted on the top of the water tank 1, the conical vane 702 is rotatably mounted on the top of the inner wall of the water tank 1, the slotted vertical rod 703 is fixedly mounted on the bottom of the inner wall of the water tank 1, the spiral piece 704 is rotatably mounted on the top of the inner wall of the water tank 1, the pressing plate 705 is sleeved on the circumferential surface of the slotted vertical rod 703, and the circumferential surface of the slotted vertical rod 703 is A limiting groove 706 is provided, the upper portion of the limiting groove 706 is spiral, and the lower portion of the limiting groove 706 is linear. The movement of the L-shaped top rod 304 drives the conical rotary vane 702 and the spiral vane 704 to rotate through the gear 701 and the transmission belt. The spiral vane 704 drives it to move downward by contacting the pressing plate 705, thereby solving the problem that the medicine floats on the water surface after supplying and cannot fully react and the problem of uneven medicine supply. The medicine floating on the water surface is pressed into the water by the pressing plate 705, thereby accelerating the reaction speed.

[0021] A medicine dispensing port is provided on the top of the water tank 1 , and the front portion of the L-shaped top rod 304 contacts the side of the spoon-shaped paddle 508 . This contact enables the back-and-forth reciprocating motion of the L-shaped top rod 304 to drive the spoon-shaped paddle 508 to deflect.

[0022] A crushing rod is fixedly installed at the bottom of the spiral groove rod 502, and a transmission rod is fixedly installed on the side of the U-shaped top rod 501. The circumferential surface of the transmission rod at one end away from the U-shaped top rod 501 contacts the inner wall of the spiral groove of the spiral groove rod 502. The up and down reciprocating motion of the U-shaped top rod 501 drives the spiral groove rod 502 to rotate through the transmission rod, thereby driving the crushing rod to rotate to crush the block medicine that cannot pass through the filter screen 503.

[0023] The tightening rod 507 is rotatably mounted on the top of the fixed end of the telescopic rod 505 at one end away from the U-shaped top rod 501, and the bottom of the telescopic rod 505 is rotatably mounted on the front of the clamping rod 506. The connection between the tightening rod 507 and the telescopic rod 505 enables the U-shaped top rod 501 to reciprocate while driving the telescopic rod 505 to reciprocate left and right, so as to realize the opening and closing movement of the clamping rod 506, thereby achieving the dredging of the medicine delivery port.

[0024] A rack is provided on the front side of the L-shaped top rod 304, which meshes with the gear 701. A transmission rod is fixedly connected to the bottom of the gear 701, and the gear 701 is fixedly connected to a pulley through the transmission rod. The transmission pulley and the conical rotor 702 are connected by a transmission belt, and the transmission pulley and the spiral piece 704 are connected by a transmission belt. The conical rotor 702 is arranged below the medicine discharge port, and the rack on the side of the L-shaped top rod 304 drives the conical rotor 702 and the spiral piece 704 to rotate through the gear 701 meshed with it. The conical rotor 702 can contact with the medicine released from the medicine discharge port and evenly spread the medicine to the center position inside the water tank 1, so that the medicine can react more fully with the circulating water.

[0025] A large filter plate 6 is fixedly installed inside the water tank 1, a water outlet pipe is provided at the front of the water tank 1, and a rotating shaft is provided on the branch of the vane wheel 303. The large filter plate 6 can achieve a rough pre-treatment of the circulating water entering the water tank 1 to improve the efficiency of subsequent processing work while improving the overall water quality treatment quality.

[0026] A vortex spring is provided between the spoon-shaped paddle 508 and the top of the water tank 1, and a return spring is provided between the L-shaped top rod 304 and the top of the water tank 1. The vortex spring and the return spring can reset the spoon-shaped paddle 508 and the L-shaped top rod 304 when the water flow decreases to reduce the supply amount of the medicine.

[0027] When working: start the motor 301 to put the device into working state, the circulating water to be treated flows into the water tank 1 through the water inlet pipe 2. When the amount of circulating water to be treated increases, that is, the flow rate and flow velocity of the circulating water flowing through the water inlet pipe 2 increase, the flow sensor 302 detects the increase in water flow rate, and the flow sensor 302 sends a signal to make the motor 301 increase the rotation speed of the output end. The rotation of the output end of the motor 301 drives the vane wheel 303 to rotate. The increase in the speed of the output end of the motor 301 also drives the speed of the vane wheel 303 to increase. When the speed of the vane wheel 303 increases, its branch on the outer side of the rotating shaft is separated from Under the action of centripetal force, it will swing outward, so that the top end of its branch contacts the rear part of the L-shaped top rod 304 and pushes the L-shaped top rod 304 to slide forward. The sliding of the L-shaped top rod 304 pushes the spoon-shaped paddle 508 in contact with its front part to rotate. After the spoon-shaped paddle 508 rotates, the medicine discharge port that was originally completely closed by it gradually opens and the greater the rotation amplitude, the greater the corresponding opening degree of the medicine discharge port. The greater the opening degree of the medicine discharge port, the more medicine passes through the medicine discharge port per unit time, thereby realizing an increase in the supply of medicine when the flow rate of circulating water increases, realizing the rational use of medicine, and improving the efficiency of medicine use. On the contrary, when the flow of circulating water flowing through the water inlet pipe 2 decreases, the flow sensor 302 sends a signal to make the motor 301 reduce the rotation speed of the output end, so that the vane wheel 303 is out of contact with the rear part of the L-shaped top rod 304. At the same time, the L-shaped top rod 304 moves backward under the action of the return spring. The L-shaped top rod 304 moves backward so that it is out of contact with the spoon-shaped paddle 508. At the same time, the spoon-shaped paddle 508 rotates in the opposite direction to the previous direction under the action of the spiral spring. The rotation of the spoon-shaped paddle 508 reduces the opening degree of the medicine outlet, thereby reducing the supply amount of medicine, avoiding unnecessary waste of medicine when the water volume is small.

[0028] When the L-shaped push rod 304 slides forward, it drives the protrusion 305 fixed on its top to move forward together. When the protrusion 305 moves forward, its convex arc surface contacts the bottom of the U-shaped push rod 501 and drives the U-shaped push rod 501 to move upward. When the U-shaped push rod 501 moves upward, it drives the transmission rod to move together. When the transmission rod moves upward, one end of the transmission rod away from the U-shaped push rod 501 contacts the inner wall of the spiral groove of the spiral groove rod 502, so that the transmission rod moves along the spiral groove. However, since the transmission rod is fixedly connected to the U-shaped push rod 501, the movement of the transmission rod drives the spiral groove rod 502 to rotate, and the rotation of the spiral groove rod 502 drives the crushing rod at its bottom to rotate. The rotation of the crushing rod achieves the purpose of breaking up the agglomerated medicine that cannot pass through the filter screen 503, thereby preventing the situation that the medicine in the cartridge 4 is blocked due to excessive medicine and the agglomeration of some medicines, which leads to a decrease in the use effect.

[0029] When the U-shaped top rod 501 moves upward, it drives the clamping rod 506 at its bottom to move upward together, and at the same time drives the tightening rod 507 connected to one end of the U-shaped top rod 501 to move upward. When the tightening rod 507 moves, the distance between the one end connected to the U-shaped top rod 501 and the inner top cover 504 is reduced. Since the other end of the tightening rod 507 is rotatably mounted on the top of the telescopic rod 505 and the top of the telescopic rod 505 is slidably mounted on the bottom of the inner top cover 504, when the tightening rod 507 is connected to one end of the U-shaped top rod 501 and moves upward, the other end of the tightening rod 507 drives the telescopic rod 505 to slide horizontally and increases the distance between the telescopic rods 505. The movement of the telescopic rod 505 drives the clamping rod 506 to move and increases the distance between them. When the U-shaped top rod 501 moves downward, the tightening rod 507 drives the distance between the telescopic rods 505 to decrease and at the same time drives the distance between the clamping rods 506 to decrease, thereby realizing the opening and closing movement of the clamping rod 506 through the up and down reciprocating movement of the U-shaped top rod 501, avoiding the blockage of the medicine that partially passes through the filter 503 when the opening of the medicine outlet is small, thereby ensuring the smoothness of the medicine supply.

[0030] When the L-shaped push rod 304 moves, it drives the rack to move along with it, and the movement of the rack drives the gear 701 to rotate. The rotation of the gear 701 drives the pulley through the transmission rod, and the rotation of the pulley drives the conical vane 702 through the transmission belt. The rotation of the conical vane 702 causes the medicine released from the medicine dispensing port to be released to the center of the water tank 1 through contact, achieving more uniform medicine dispensing. At the same time, the pulley drives the spiral vane 704 through the transmission belt. The rotation of the spiral vane 704 drives the pressing plate 705 downward along the limiting groove 706 by contacting it. Because the limiting groove 706 has a spiral front portion and a straight rear portion, the pressing plate 705 rotates a certain angle before moving downward along the limiting groove 706. This achieves the purpose of pressing the medicine floating on the water surface into the water, while preventing the medicine from scattering on the top of the pressing plate 705 during the dispensing process, resulting in insufficient use. This speeds up the reaction speed and improves the quality of the treated water.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
