Description

Technical Field

[0001] The utility model relates to the technical field of online cleaning, in particular to an online cleaning device. Background Art

[0002] After the condenser has been working for a long time, a large amount of scale, dirt, and biological sludge accumulate on the inner wall of the tube, which reduces the heat transfer efficiency of the condenser. The traditional treatment methods for condenser tube dirt are chemical water treatment and periodic manual mechanical brushing. However, chemical water treatment cannot completely solve the problem of dirt, slime deposition, bacteria, algae, and rust, so regular mechanical brushing is required. Traditional treatment methods are time-consuming and labor-intensive. Nowadays, the condenser online cleaning device replaces the regular mechanical brushing to keep the condenser tube in a clean state.

[0003] The working principle of the condenser online cleaning device is: the ball collector and ball driver sends the cleaning rubber balls into the condenser, and the rubber balls rely on the high flow rate of cooling water to scrub the dirt on the inner wall of the condenser heat exchange copper tube, and the rubber balls are recovered through the ball-water separator at the cooling water outlet to form a cleaning cycle. To maintain the continuous cleaning of the condenser tube by the rubber balls, the rubber balls must be continuously sent into the cleaning system, and then the rubber balls that have cleaned the cooling tubes are promptly recovered and used again for cleaning. The ball-water separator is used to collect all the rubber balls dispersed in the cooling water for reuse, so the ball collection rate and the ball serving rate of the ball-water separator are very important. The existing pump-free online cleaning device has limited power for the cleaning rubber balls because it is not equipped with a water pump to suck the cleaning rubber balls, and the space design of the ball-water separator is large, and the cleaning rubber balls are easy to swirl or stay in it, affecting the serving rate, and thus affecting the cleaning effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments. Terms such as "upper", "inner", "middle", "left", "right" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present utility model. Changes or adjustments in their relative relationships shall also be regarded as the scope of implementation of the present utility model without substantial changes in technical content.

[0026] Such as Figures 1 to 3As shown in the figure, the on-line cleaning device of the present utility model is mainly applied to the device to be cleaned, especially for on-line cleaning of condensers, and mainly includes a water inlet pipe 1, a water outlet pipe 2, a ball collecting bin 3, a water inlet pipeline 4, a ball sending pipe 5, a ball collecting pipe 6 and a drainage pipeline 7. Among them, the water inlet pipe 1 is connected to the water inlet of the device to be cleaned, and the water outlet pipe 2 is connected to the water outlet of the device to be cleaned. The water inlet pipeline 4 is connected to the ball sending pipe 5 through the ball collecting bin 3. The water inlet of the water inlet pipeline 4 is communicated with the water inlet pipe 1, and the ball sending port of the ball sending pipe 5 is communicated with the water inlet pipe 1. Specifically, the water inlet of the water inlet pipeline 4 and the ball sending port of the ball sending pipe 5 can be arranged in the water inlet pipe 1. The ball collecting pipe 6 is connected to the drainage pipeline 7 through the ball collecting bin 3. The ball collecting port of the ball collecting pipe 6 is communicated with the water outlet pipe 2, and the drainage port of the drainage pipeline 7 is communicated with the water outlet pipe 2. Specifically, the ball collecting port of the ball collecting pipe 6 and the drainage port of the drainage pipeline 7 can be arranged in the water outlet pipe 2. Among them, the ball collecting bin 3 is designed as a long strip-shaped tubular structure, with a narrow and long straight space, and the cleaning rubber balls will not rotate or stay inside. When the cleaning is started, the cooling water rushes over, which is beneficial to ball sending and greatly improves the ball sending rate. Preferably, the diameter of the body of the ball collecting bin 3 is the same as that of the water inlet pipeline 4 and the drainage pipeline 7, or the diameter of the body of the ball collecting bin 3 is larger than that of the water inlet pipeline 4 and the drainage pipeline 7. The diameters of the water inlet pipeline 4 and the drainage pipeline 7 are the same.

[0027] As Figure 4 shown, the ball collecting pipe 6 mainly includes a ball collecting pipe body 62 and an assisting pipe 63 which are connected in sequence. The ball collecting pipe body 62 is in a horn-shaped structure. The wide mouth end of the ball collecting pipe body 62 is connected to the inlet of the water outlet pipe 2 (the cooling water and the cleaning rubber ball recovery port) so as to connect all the cleaning rubber balls and cooling water after cleaning into the ball collecting pipe 6. The narrow mouth end of the ball collecting pipe body 62 is connected to the assisting pipe 63. Filter holes are arranged on the pipe body of the ball collecting pipe body 62. Most of the cooling water entering the ball collecting pipe 6 flows into the water outlet pipe 2 through the filter holes of the ball collecting pipe body 62 and is discharged. The horn-shaped ball collecting pipe body 62 is beneficial to recovering the cleaning rubber balls. The pipe body of the assisting pipe 63 is linear, and filter holes are arranged on the pipe body of the assisting pipe 63. Since the flow rate of the cooling water becomes smaller after passing through the ball collecting pipe body 62, the power to push the cleaning rubber ball forward also becomes smaller. At this time, adding a section of assisting pipe 63 in the shape of a filter net can introduce a larger amount of water, which can increase the forward power for the cleaning rubber ball, and the entry of the cleaning rubber ball becomes smooth. Since the assisting pipe 36 is linear, the cleaning rubber ball will not adsorb and stay in the assisting pipe 63 after entering, and continues to move forward to the ball collecting bin 3, which is beneficial to improving the ball collecting rate. Preferably, the length of the assisting pipe 63 is about 3CM.

[0028] In order to further accelerate the flow rate of the cleaning rubber balls, an accelerating pipe 64 is also arranged between the ball collecting pipe body 62 and the assisting pipe 63. The pipe body of the accelerating pipe 64 is linear, and the pipe body of the accelerating pipe 64 is made of a sealing plate, that is, the accelerating pipe 64 is solid. Preferably, the length of the accelerating pipe 64 is 2-3CM.

[0029] In order to smoothly recycle the cleaning rubber balls into the ball collecting bin 3, a transition pipe 65 is further provided between the boosting pipe 63 and the ball collecting bin 3. The pipe body of the transition pipe 65 is made of a sealing plate, that is, the transition pipe 65 is a solid. One end of the transition pipe 65 connected to the boosting pipe 63 can be provided with a straight section, and the straight section can make it easier for the cleaning rubber balls to enter the ball collecting bin 3.

[0030] The ball collecting bin 3 includes a ball collecting bin body 31 and a filtering structure arranged inside the ball collecting bin body 31. The filtering structure is provided to prevent excessive water accumulation in the ball collecting bin 3, so that the cleaning rubber balls are blocked in the ball collecting bin 3 and cannot move forward.

[0031] When the diameter of the ball collecting bin body 31 is consistent with the diameters of the water inlet pipe 4 and the drain pipe 7, the filtering structure specifically includes a first filter screen 32 and a second filter screen 33 which are connected to each other. As Figure 5 shown, since the diameter of the ball collecting bin body 31 is not large, the first filter screen 32 is a sheet structure and is only laid at the bottom inside the ball collecting bin body 31, allowing the excess cooling water to pass through the first filter screen 32 and drain out, separating from the cleaning rubber balls to avoid congestion. The second filter screen 33 is horizontally arranged at the tail of the ball collecting bin body 31 and is sized to fit the tail of the ball collecting bin body 31. The second filter screen 33 is used to prevent the cleaning rubber balls from flowing out of the ball collecting bin 3.

[0032] When the diameter of the ball collecting bin body 31 is larger than the diameters of the water inlet pipe 4 and the drain pipe 7, the filtering structure includes a third filter screen 34 and a fourth filter screen 35 which are connected to each other. As Figure 6 shown, due to the relatively large diameter of the ball collecting bin body 31, the third filter screen 34 can be set as a cylindrical structure and directly inserted into the inside of the ball collecting bin body 31, allowing the excess cooling water to pass through the third filter screen 34 and drain out, separating from the cleaning rubber balls to avoid congestion. The fourth filter screen 35 is horizontally arranged at the tail of the ball collecting bin body 31 and is sized to fit the tail of the ball collecting bin body 31. The fourth filter screen 35 is used to prevent the cleaning rubber balls from flowing out of the ball collecting bin 3.

[0033] For the convenience of automatic control, the on-line cleaning device further includes a controller 9, a first three-way electric valve 10 and a second three-way electric valve 11. The water inlet pipe 4, one end of the ball collecting bin 3 and the drain pipe 7 are connected through the first three-way electric valve 10, and the ball sending pipe 5, the other end of the ball collecting bin 3 and the ball receiving pipe 6 are connected through the second three-way electric valve 11. The controller 9 is electrically connected to the first three-way electric valve 10 and the second three-way electric valve 11 respectively. The upper connection of the first three-way electric valve 10 and the second three-way electric valve 11 is the ball receiving state, and the lower connection of the first three-way electric valve 10 and the second three-way electric valve 11 is the ball sending state. Using two three-way electric valves can further simplify the electrical components and reduce the failure rate.

[0034] The working process of the present utility model:

[0035] When online cleaning of the condenser is required, cooling water enters from the water inlet pipe 1. The controller 9 controls the upper connections of the first three-way electric valve 10 and the second three-way electric valve 11. At this time, the cooling water enters the water inlet pipeline 4 simultaneously. The cooling water passes through the ball collection bin 3, flushing the clean rubber balls in the ball collection bin 3 to the ball sending pipe 5. The balls fall into the water inlet pipe 1 through the ball sending pipe 5 and then enter the condenser for cleaning. After the cleaning is completed, the cooling water and the clean rubber balls flow out together to the water outlet pipe 2 and flow into the ball collection bin 3 through the ball collection pipe 6. A large amount of cooling water flows out through the filter holes of the ball collection pipe 6 to the water outlet pipe 2 for drainage. After a small amount of cooling water enters the ball collection bin 3 along with the clean rubber balls, it is discharged to the water outlet pipe 2 through the drainage pipeline 7. Thus, a cleaning cycle is completed.

[0036] The utility model has a simple structure and is convenient to use, which can greatly improve the ball sending rate and the ball collection rate, and ensure the cleaning effect.

[0037] The implementation mode of the utility model is not limited to this. According to the above content of the utility model, by using the ordinary technical knowledge and conventional means in the field, without departing from the above basic technical idea of the utility model, the utility model can also be modified, replaced or combined in many other forms, all of which fall within the scope of the protection of the utility model rights.
