Description

Technical Field

[0001] This invention relates to a device for monitoring the circulation of rubber balls, belonging to the field of rubber ball counting. Background Technology

[0002] The cleanliness of circulating water systems is crucial for ensuring the normal operation of industrial production. As an important component of circulating water systems, ball cleaning devices are used in power plant condenser circulating cooling water systems. They effectively remove scale from the inner walls of condenser cooling tubes without shutting down the unit or reducing load, extending the service life of the cooling tubes, reducing condenser terminal temperature difference, increasing condenser vacuum, and improving turbine thermal efficiency. The circulation of the balls is a vital part of the circulating water system. Statistical analysis of the number of these circulating balls, calculating the ball recovery rate over a single cycle or period, allows for better optimization of the overall layout of the ball cleaning device.

[0003] Chinese invention patent CN115077293A discloses a photoelectric detection ball counter. This counter has a counter pipe installed on the ball washing and return pipe, with a photoelectric switch on each side of the counter pipe. By counting the number of times the photoelectric switch is blocked and the duration of the blocking as the ball passes through, the number of balls recovered can be calculated, further estimating the ball recovery rate and monitoring the operating status of the ball washing system. However, in the prior art, the balls can only pass through the counting pipe in a single file, which not only affects the counting speed but also easily leads to ball congestion, reducing the ball circulation efficiency.

[0042] like Figure 1-10 As shown, a ball circulation monitoring device in this embodiment includes a housing 1, an input pipe 2 connected to the right side of the housing 1, an output pipe 3 connected to the left side of the housing 1, and a counting mechanism 4 provided on the housing 1.

[0043] The counting mechanism 4 includes a counting base 41, which is located inside the housing 1. The counting base 41 is provided with a first through hole 42, which extends to the left and right sides of the counting base 41. The axis of the first through hole 42 is parallel to the left and right direction. The cavity inside the input pipe 2, the cavity inside the first through hole 42, and the cavity inside the output pipe 3 form a transmission channel.

[0044] A valve 43 is provided on one side of the counting base 41, and the valve 43 is used to seal the first through hole 42;

[0045] The valve 43 includes a water cap 431, which covers the side of the counter seat 41 near the input pipe 2. An opening and closing assembly 432 is connected to the water cap 431, which is used to open and close the water cap 431.

[0046] The opening and closing assembly 432 includes a drive shaft 4321, which passes through the input pipe 2. The drive shaft 4321 is rotatably and sealedly connected to the input pipe 2. The water cap 431 is fixedly mounted on the drive shaft 4321. The drive shaft 4321 is driven by a first motor 4322.

[0047] The counting base 41 is provided with two sets of counting components 44, each set of counting components 44 is provided with three, and the three counting components 44 in the same set are evenly distributed circumferentially with the first through hole 42 as the center.

[0048] The counting component 44 includes a second through hole 441, which extends through to the left and right sides of the counting base 41. The axis of the second through hole 441 is parallel to the axis of the first through hole 42. The cavity inside the input tube 2, the cavity inside the second through hole 441, and the cavity inside the output tube 3 form a counting channel. A set of counting holes 442 is provided on the inner wall of the second through hole 441. The counting holes 442 extend to the outer wall of the counting base 41. A photoelectric sensor is installed in the counting holes 442.

[0049] The projections of each counting hole 442 on the counting base 41 along the left and right directions are arranged in a centrally symmetrical manner with respect to the first through hole 42.

[0050] In the two sets of counting components 44, the three second through holes 441 in one set of counting components 44 are arranged alternately with the three second through holes 441 in the other set of counting components 44, and the counting holes 442 in one set and the counting holes 442 in the other set are distributed from left to right.

[0051] The diameter of the first through hole 42 is larger than the diameter of the second through hole 441;

[0052] This rubber ball circulation monitoring device has two operating modes:

[0053] In the first state, valve 43 is in the closed state, and water cap 431 seals the first through hole 42.

[0054] In the second state, valve 43 is in the open state, and water cap 431 is separated from counter seat 41;

[0055] When transitioning between the first state and the second state, the first motor 4322 starts, causing the transmission shaft 4321 to drive the water cap 431 to rotate.

[0056] In the first state, which is the counting state, water and glue balls are transported from the input pipe 2 to the housing 1. The water and glue balls in the housing 1 are then discharged from the output pipe 3. The water and glue balls in the housing 1 can only pass through the second through hole 441. That is, the water and glue balls move in the counting channel. When the glue ball passes through the second through hole 441, it is detected and counted by the photoelectric sensor.

[0057] In the second state, water and glue balls are transported from the input pipe 2 into the housing 1, and the water and glue balls in the housing 1 are discharged from the output pipe 3. The water and glue balls in the housing 1 pass through the first through hole 42 and the second through hole 441 respectively. That is, the water and glue balls move in the counting channel and the transmission channel. At this time, the photoelectric sensor stops counting. By setting multiple second through holes 441, glue ball congestion during the counting process is avoided, and the counting efficiency is improved.

[0058] A filter mechanism 5 is provided on the input pipe 2. The filter mechanism 5 includes a filter cylinder 51, which is frustoconical in shape. The filter cylinder 51 is coaxially arranged with the first through hole 42 and is located inside the input pipe 2. A gap is provided between the filter cylinder 51 and the inner wall of the input pipe 2. The filter cylinder 51 is fixedly connected to the input pipe 2. The filter cylinder 51 is provided with filter holes 52. The small diameter end of the filter cylinder 51 is arranged away from the counting seat 41. The large diameter end of the filter cylinder 51 is sealed and fixedly provided with a sealing plate 59. The sealing plate 59 is provided with a first circular hole 53. A sealing block 54 is inserted into the first circular hole 53. The sealing block 54 is provided with a second circular hole 55. A filter screen 56 is installed in the second circular hole 55. A rotating component 57 is provided on the sealing block 54. The rotating component 57 is used to drive the sealing block 54 to rotate.

[0059] The rotating assembly 57 includes a rotating shaft 571, which vertically passes through the outer wall of the input pipe 2. The rotating shaft 571 is rotatably and sealed to the input pipe 2. The rotating shaft 571 is driven by a second motor 572. One end of the rotating shaft 571 is fixedly mounted on the sealing block 54. The rotating shaft 571 is located on the side of the sealing plate 59 near the cover 1.

[0060] In the first state, the sealing block 54 is inserted into the first circular hole 53, and the sealing block 54 seals the inner wall of the first circular hole 53. The second circular hole 55 is connected to the inner cavity of the filter cylinder 51. When the water and rubber balls in the input pipe 2 flow from right to left to the outer wall of the filter cylinder 51, calculations show that the rubber balls cannot pass through the filter hole 52. This is because the rubber balls inevitably expand and deform during the cleaning process. The expanded rubber balls are easy to break. The broken rubber ball fragments pass through the filter hole 52 and enter the inner cavity of the filter cylinder 51. The rubber ball fragments in the inner cavity of the filter cylinder 51 then enter the second circular hole 55 and are intercepted by the filter screen 56. In this way, the rubber ball fragments are prevented from entering the second through hole 441 and affecting the accuracy of the counting.

[0061] In the second state, the sealing block 54 is separated from the sealing plate 59, and the sealing block 54 is located on the side of the sealing plate 59 closer to the cover 1. At this time, the rubber ball fragments in the inner cavity of the filter cartridge 51 are discharged from the first round hole 53 and enter the first through hole 42 and the second through hole 441, while the rubber ball fragments originally trapped on the first filter screen 56 enter the first through hole 42 and the second through hole 441 with the water flow.

[0062] The frustum-shaped filter cylinder 51 facilitates the movement of the rubber ball along a direction perpendicular to the axis of the first through hole 42 toward the direction of approaching the second through hole 441, thus allowing the rubber ball to enter the second through hole 441.

[0063] When switching between the first state and the second state, the second motor 572 starts, causing the rotating shaft 571 to drive the sealing block 54 to rotate;

[0064] An auxiliary tube 58 is provided inside the filter cartridge 51. The auxiliary tube 58 is frustoconical and coaxially arranged with the filter cartridge 51. The small-diameter end of the auxiliary tube 58 is arranged towards the housing 1. The inner diameter of the small-diameter end of the auxiliary tube 58 is larger than that of the first circular hole 53. The small-diameter end of the auxiliary tube 58 is sealed and fixedly disposed on the side of the sealing plate 59 away from the housing 1. The outer wall of the large-diameter end of the auxiliary tube 58 is sealed and fixedly disposed on the inner wall of the filter cartridge 51. The filter hole 52 is located on the side of the auxiliary tube 58 away from the housing 1. The auxiliary tube 58 facilitates the movement of the rubber ball fragments inside the filter cartridge 51 to the first through hole 42.

[0065] In summary, by setting multiple second through holes 441, the clogging of the rubber balls during the counting process is avoided, thus improving the counting efficiency. Moreover, during the counting process, rubber ball fragments can be filtered out, preventing them from entering the second through holes 441 and affecting the counting accuracy.

[0066] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
