Description

Technical Field

[0001] The utility model belongs to the technical field of condenser cleaning, and in particular relates to a ball blocking filter plug and a condensation system. Background Art

[0002] At present, most refrigeration cooling water systems are open. The cooling towers are exposed to sunlight, wind and rain outdoors, which causes dust and debris to enter the containers. Serious sediments and a large number of microorganisms will be produced in the cooling water system. The slime and dirt formed will be deposited and adsorbed on the water side surface of the heat exchange copper tube of the unit condenser, resulting in poor condensation effect during unit operation. The condensation pressure is higher than the design condition, causing the unit's refrigeration efficiency to decrease. In severe cases, it may even affect the normal operation of the unit.

[0003] For example, in Chinese patent CN202211231386.8, existing refrigerators often use condenser rubber ball automatic online cleaning devices to remove dirt on the copper tube surface. The cleaning rubber ball is sent from the ball injector to the condenser by using the system's own water pump to pressurize. The scale, dirt and microbial film on the inner wall of the heat exchange tube are scrubbed off by the flushing force generated by the water flow and the friction between the rubber ball and the inner wall of the heat exchange tube. At the cooling water outlet, the ball is recovered to the ball injector by the ball return device using the principle of hydraulic mechanics, thus completing a cleaning cycle.

[0004] During the regular maintenance of the automatic online cleaning device for the condenser rubber balls, the applicant found that the number of circulating rubber balls would decrease with the increase of operating time. When disassembling the refrigerator condenser, it was found that the lost rubber balls would be stuck in the heat exchange pipes. This phenomenon is mainly caused by the following reasons: 1. The refrigerator and the rubber balls are not compatible. Other structures of the refrigerator condenser, such as end covers and beams, may block part of the pipes, causing the rubber balls entering and exiting the pipes to get stuck; 2. Impurities in the cooling water clogged the copper pipes, causing the rubber balls to get stuck. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figure 1-4 Some embodiments of the present application provide a ball blocking filter plug 100 for filtering rubber balls 204 for cleaning pipelines, including a filter blocking portion 1 that can block the rubber balls 204; and also including a connecting portion 2 for detachably connecting to the pipeline, and liquid can enter the pipeline through the filter blocking portion 1 and the connecting portion 2.

[0030] The implementation of the filter blocking part 1 is not limited, as long as it can block the rubber ball 204 and allow the liquid to flow through. For example, it can be set as a cylinder with a plurality of filter holes 12 on one side, and the size of the filter holes 12 can prevent the rubber ball 204 from passing through.

[0031] The filter blocking part 1 of the ball blocking filter plug 100 can block the rubber ball 204 from entering the pipeline that is not suitable for cleaning with the rubber ball 204, while having little impact on the internal liquid, to prevent the rubber ball 204 from clogging and stagnating in the pipeline, resulting in system performance degradation or even production accidents. The connecting part 2 is used to connect to the pipeline, and the use of a detachable connection method can make the ball blocking filter plug 100 of the present application applicable to more systems, and is convenient for cleaning and maintenance.

[0032] The end of the filter block 1 away from the connection part 2 can be closed or open. In some embodiments, the end of the filter block 1 away from the connection part 2 is set to be open to increase the unit flow rate of the liquid entering the pipeline; a blocking bar 11 that can block the rubber ball is provided at the opening, and the setting of the blocking bar 11 can separate the end opening of the filter block 11 to prevent the rubber ball 204 from passing through. Preferably, the blocking bar 11 at the end is set to be a cross-shaped bar to give it better structural strength and reduce the probability of damage.

[0033] Considering that the pipe equipped with the ball-blocking filter plug 100 is no longer cleaned by the rubber ball 204, which may cause impurities to accumulate in the pipe, in some embodiments, a filter screen 4 is also included on the inner side of the filter block 1. The filter screen 4 is used to compensate for the cleaning effect of the rubber ball 204, that is, to filter impurities in the liquid to prevent hard impurities from entering the pipe and causing flow reduction, diameter reduction, and blockage. The filter screen 4 can adopt a barrel-shaped structure, with the barrel bottom filtering the end face and the barrel wall blocking and filtering the side face. It is also possible to adopt a plurality of annular structures arranged step by step along the axial direction, with a stage arranged behind each layer of filter holes.

[0034] In order to prevent the filter block 1 from being washed into the pipeline and causing the side of the filter block 1 to lose the effect of blocking rubber balls and filtering impurities, in some embodiments, a positioning portion 3 is included to prevent the filter block 1 from entering the pipeline.

[0035] The implementation of the positioning part 3 is not limited. In some implementations, the positioning part 3 is a positioning rib, which is arranged on the side of the filter-blocking part 1 and has the same length as the filter-blocking part 1, and can abut against the pipeline to prevent the filter-blocking part 1 from entering the pipeline. In this way, the positioning part 3 is arranged. In addition to the positioning function, the positioning rib can also strengthen the structural strength of the filter-blocking part 1 and reduce the probability of deformation and damage.

[0036] In some embodiments, the connection portion 2 includes a fastener 21 that can squeeze the pipe to generate elastic deformation to strengthen the connection when inserted into the pipe, such as a convex ring or a convex point.

[0037] In some embodiments, the filter blocking part 1 and the connecting part 2 are integrally injection molded. Since the filter blocking part 1 and the connecting part 2 of the present application have simple structures and can be directly connected, the integral injection molding can eliminate the assembly link, increase the overall strength, and eliminate potential failure points. The use of injection molding can better meet the use strength requirements of the ball blocking filter plug 100 and is in line with the use scenario of the ball blocking filter plug 100.

[0038] Please refer to Figure 5 The present application also provides an embodiment of a condensation system, including a condenser and a rubber ball cleaning device for providing rubber balls 204 to the condenser to clean the condenser. The condenser includes a heat exchange pipe, and the heat exchange pipe is provided with the above-mentioned ball blocking filter plug 100, which has all the beneficial effects of the above-mentioned ball blocking filter plug 100.

[0039] In some embodiments, the condenser includes a turning cavity 205 and a sewage outlet 206 communicating with the turning cavity 205, the heat exchange pipe includes an inlet pipe 201 and an outlet pipe 202, the liquid in the inlet pipe 201 flows into the outlet pipe 202 through the turning cavity 205, and the ball blocking filter plug 100 is arranged at the inlet of the outlet pipe 202. The ball blocking filter plug 100 is arranged at the inlet of the outlet pipe 202, so that the filtered rubber balls 204 or impurities are deposited in the turning cavity 205 and discharged through the sewage outlet 206.

[0040] Combine the following Figure 1-4 Example 1 of the present application is listed, a ball blocking filter plug 100, including a filter blocking part 1 and a connecting part 2, the filter blocking part 1 is cylindrical, with a cross-shaped blocking strip 11 at the end, and a plurality of filter holes 12 on the side; the connecting part 2 has a fastener 21 on the side, and the fastener 21 is specifically two convex rings, and the convex rings can be interference fit with the pipe that needs to block the rubber ball 204. This ball blocking filter plug 100 embodiment also includes four positioning ribs evenly arranged on the side of the filter blocking part 1. In this embodiment, there is a smooth transition between the filter blocking part 1 and the connecting part 2, and the filter blocking part 1, the connecting part 2 and the positioning ribs are integrally injection molded. This embodiment also includes a filter screen 4 arranged on the inner side of the filter blocking part 1, and the filter screen 4 is cylindrical and covers the inner side of the filter blocking part 1.

[0041] When in use, the connecting part 2 is inserted into the pipe that needs to block the rubber ball 204 from entering, and the filter blocking part 1 can block the rubber ball 204 from entering, so that the rubber ball 204 can be discharged through other pipes or through the sewage outlet 206. The filter screen in the filter blocking part 1 can filter hard impurities.
