Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to an automatic cleaning device for hydrogen conductivity meter resin. Background Art

[0002] The online hydrogen conductivity meter is an instrument used in power plants to monitor the quality of water vapor such as boiler feed water, condensate, steam, and polishing. Hydrogen conductivity is an important indicator of water vapor quality. Hydrogen conductivity is the conductivity value obtained by measuring the water sample through the ion exchange resin. The resin needs to be regenerated after working for a period of time, otherwise it will seriously affect the detection value of water quality hydrogen conductivity.

[0003] The existing hydrogen conductivity meter resin regeneration and flushing device (Announcement No.: CN217189630U) has at least the following disadvantages: When the above patent is in use, acid is flushed into the resin container through two hoses and a flushing pipe to flush the resin in the resin container. After the resin is flushed, the used acid is discharged back into the acid tank through a curved pipe. The acid flows along the inner wall of the cone into the filter and is filtered through the filter. The filtered acid can be reused. Since dirt will adhere to the surface of the resin when it is in use, the above patent cannot flush the dirt on the surface of the resin only by flushing, which affects the subsequent detection value of hydrogen conductivity.

The base 1 is provided with a belt The driving mechanism for moving the U-shaped slide 5 includes two support plates 13 symmetrically fixedly mounted on the upper surface of the base 1, a crankshaft 14 is rotatably mounted between the two support plates 13, a curved neck 15 is provided on the outer surface of the crankshaft 14, a connecting rod 16 is rotatably mounted between the inner walls of the curved neck 15, and the other end of the connecting rod 16 is rotatably mounted on the lower surface of the U-shaped slide 5, a driving motor 17 is fixedly mounted on the outer surface of one of the support plates 13, and the output end of the driving motor 17 passes through the outer surface of the support plate 13 and is fixedly mounted on the rotation center of the crankshaft 14.

[0020] The crankshaft 14 is driven to rotate by the driving motor 17, so that the crankshaft 14 drives the curved neck 15 to rotate eccentrically, and the curved neck 15 drives the U-shaped slide plate 5 to move back and forth through the connecting rod 16. The reciprocating movement of the U-shaped slide plate 5 causes the U-shaped slide plate 5 to move relative to the washboard 27. The hydrogen conductivity meter resin between the U-shaped slide plate 5 and the washboard 27 can be rubbed by this device, and the dirt on the surface of the hydrogen conductivity meter resin can be quickly removed, thereby ensuring the stability of the subsequent hydrogen conductivity detection value.

[0021] In this embodiment, a feed hopper 6 is fixedly installed at one end of the U-shaped slide 5, and the feed hopper 6 is arranged at the raised end of the U-shaped slide 5.

A driving groove 10 is penetrated through the outer surface of the driving plate 9 near the bottom, and the driving column 12 is slidably installed with the inner wall of the driving groove 10.

[0022] The reciprocating movement of the U-shaped slide plate 5 causes the driving plate 9 to move, and the driving plate 9 drives the rotating rod 7 to rotate reciprocally through the cooperation of the driving groove 10 and the driving column 12, so that the rotating rod 7 drives the paddle 8 to swing reciprocally, and the paddle 8 will intermittently make the hydrogen conductivity meter resin inside the feed hopper 6 fall into the inside of the U-shaped groove. The device is convenient for intermittently controlling the falling amount of the hydrogen conductivity meter resin, which is convenient for subsequent cleaning.

[0023] In this embodiment, two T-shaped slide rails 29 are symmetrically fixedly installed on the top wall of the shield 2, and two connecting plates 30 are symmetrically slidably installed on the outer surfaces of the two T-shaped slide rails 29. A two-way screw rod 28 is symmetrically rotatably installed between the inner walls on opposite sides of the shield 2. The two-way screw rod 28 passes through the outer surfaces of the two connecting plates 30 and is threadedly connected thereto. One end of the two-way screw rod 28 passes through the outer surface of the shield 2 and is fixedly installed with a knob 32. Two support rods 31 are symmetrically rotatably installed on the outer surfaces of the two connecting plates 30. The two support rods 31 are rotatably installed on the upper surface of the washboard 27. Two T-shaped grooves are symmetrically provided on the lower surfaces of the two connecting plates 30, and the two T-shaped slide rails 29 are slidably installed on the inner walls of the T-shaped grooves.

[0024] By manually rotating the knob 32, the knob 32 drives the bidirectional screw rod 28 to rotate, and the bidirectional screw rod 28 drives the two connecting plates 30 to move closer to each other. The connecting plate 30 drives the rubbing plate 27 to move closer to the U-shaped slide plate 5 through the support rod 31, so that the gap between the rubbing plate 27 and the U-shaped groove becomes smaller. The device can adjust the pressure of the hydrogen conductivity meter resin being rubbed so that the dirt on its surface can be fully removed.

[0025] In this embodiment, a sieve plate 24 is fixedly installed at one end of the base 1 away from the feed hopper 6. The sieve plate 24 is inclined and is arranged directly below the U-shaped slide plate 5. A limiting slide bar 22 is fixedly installed between the inner walls on opposite sides of the shield 2. A scraper 23 is slidably installed on the outer surface of the limiting slide bar 22. The lower surface of the scraper 23 is against the upper surface of the sieve plate 24. A reciprocating screw 21 is rotatably installed between the inner walls on opposite sides of the shield 2. The reciprocating screw 21 passes through the outer surface of the scraper 23 and is threadedly connected to it. A second pulley 20 is fixedly installed on the outer surface of one end of the reciprocating screw 21, and a first pulley 18 is fixedly installed on the outer surface of one end of the crankshaft 14. A belt 19 is sleeved on the outer surfaces of the first pulley 18 and the second pulley 20.

[0026] The crankshaft 14 drives the first pulley 18 to rotate, so that the first pulley 18 drives the second pulley 20 to rotate through the belt 19, and the second pulley 20 drives the reciprocating screw 21 to rotate, and the reciprocating screw 21 drives the scraper 23 to slide back and forth along the limiting slide bar 22. Through this device, the hydrogen conductivity table resin that falls onto the surface of the sieve plate 24 after cleaning can be scraped into the collection boxes on both sides of the sieve plate 24 for subsequent use.

[0027] In this embodiment, a water pipe 25 is fixedly installed on the upper surface of the rubbing board 27 near one end of the feed hopper 6, and a plurality of nozzles are fixedly installed at equal intervals on the outer surface of the water pipe 25. The nozzles are arranged above the discharge end of the feed hopper 6. A water pipe joint 26 is fixedly installed on the upper surface of one end of the water pipe 25, and the water pipe joint 26 is connected to the nozzle through the water pipe 25.

[0028] The water pipe 25 is connected to the external cleaning water through a hose and a water pipe joint 26. The cleaning water adopts a solution of about 4% industrial hydrochloric acid. The solution is sprayed into the U-shaped groove of the U-shaped slide plate 5 through a nozzle to wash the hydrogen conductivity meter resin.

[0029] In this embodiment, a square tube 33 is slidably inserted into the upper surface of the shield 2, and a trapezoidal block is fixedly installed on the bottom end of the square tube 33 through the lower surface of the washboard 27, and the trapezoidal block is connected to the interior of the square tube 33. Elastic diaphragms 34 are provided on the outer surfaces of the opposite sides of the trapezoidal block, and a piston 37 is slidably installed on the inner wall of the square tube 33. An indicator column is fixedly installed on the upper surface of the piston 37, and the indicator column passes through the top end of the square tube 33 and is slidably installed therewith, and the lower surface of the trapezoidal block abuts against the bottom wall of the U-shaped groove.

[0030] When the dirt on the surface of the hydrogen conductivity meter resin is washed away, the gaps between the resins will become larger. At this time, the elastic diaphragm 34 will not be subjected to the squeezing force. When the gap between the U-shaped slide plate 5 and the washboard 27 is larger, the hydrogen conductivity meter resin cannot be fully rubbed, so that the dirt is not fully removed, thereby making the gaps between the resins smaller, squeezing the elastic diaphragm 34. The elastic diaphragm 34 compresses the air inside the square cylinder 33, causing the piston 37 to move up and drive the indicator column to move up. The operator can intuitively see whether the hydrogen conductivity meter resin has been cleaned.

[0031] It should be noted that, before use, the present invention connects the water pipe 25 with external cleaning water through a hose and a water pipe joint 26. The cleaning water is a solution of about 4% industrial hydrochloric acid, which is sprayed into the U-shaped groove of the U-shaped slide 5 through a nozzle to rinse the hydrogen conductivity meter resin. When in use, the operator adds the hydrogen conductivity meter resin to be cleaned into the inside of the feed hopper 6, drives the crankshaft 14 to rotate through the drive motor 17, and drives the crankshaft 14 to drive the curved neck 15 to rotate eccentrically. The curved neck 15 drives the U-shaped slide 5 to reciprocate through the connecting rod 16. The reciprocating movement of the U-shaped slide 5 causes the driving plate 9 to move. The driving plate 9 drives the rotating rod 7 to reciprocate through the cooperation of the driving groove 10 and the driving column 12. The rotating rod 7 drives the paddle 8 to swing back and forth, and the paddle 8 will intermittently make the hydrogen conductivity meter resin inside the feed hopper 6 fall into the inside of the U-shaped groove. Through this device, it is convenient to intermittently control the falling amount of the hydrogen conductivity meter resin, which is convenient for subsequent cleaning; the reciprocating movement of the U-shaped slide plate 5 makes it move relative to the washboard 27. Through this device, the hydrogen conductivity meter resin between the U-shaped slide plate 5 and the washboard 27 can be rubbed, and the dirt on the surface of the hydrogen conductivity meter resin can be quickly removed, ensuring the stability of the subsequent hydrogen conductivity detection value; the first pulley 18 is driven to rotate by the crankshaft 14, so that the first pulley 18 drives the second pulley 20 to rotate through the belt 19, and the second pulley 20 drives the reciprocating screw rod 21 to rotate, The reciprocating screw rod 21 drives the scraper plate 23 to slide back and forth along the limiting slide bar 22. Through this device, the hydrogen conductivity table resin that falls on the surface of the sieve plate 24 after cleaning can be scraped into the collection boxes on both sides of the sieve plate 24 for subsequent use. The hydrogen conductivity table resin that falls on the surface of the sieve plate 24 is filtered by the sieve plate 24, so that its internal cleaning is easy to fall into the recovery box for subsequent reuse. When the dirt on the surface of the hydrogen conductivity table resin is washed clean, the gap between the resins will become larger. At this time, the elastic diaphragm 34 will not be squeezed. When the gap between the U-shaped slide plate 5 and the rubbing board 27 is large, the hydrogen conductivity table resin cannot be fully rubbed at this time, so that the dirt on the surface is not fully removed, thereby The gap between the resins is smaller, which will squeeze the elastic diaphragm 34. The elastic diaphragm 34 compresses the air inside the square cylinder 33, so that the piston 37 moves up and drives the indicator column to move up. The operator can intuitively see whether the hydrogen conductivity meter resin is cleaned. When the hydrogen conductivity meter resin is not cleaned, the knob 32 is manually turned to make the knob 32 drive the bidirectional screw rod 28 to rotate, and the bidirectional screw rod 28 drives the two connecting plates 30 to move closer to each other. The connecting plate 30 drives the rubbing plate 27 to move closer to the U-shaped slide plate 5 through the support rod 31, so that the gap between the rubbing plate 27 and the U-shaped groove becomes smaller. The device can adjust the pressure of the hydrogen conductivity meter resin being rubbed so that the dirt on its surface can be fully removed.
